摘要： Labor-saving paint mixing cover comprises a paint outlet mechanism used to control outflow of a paint material, two or more pressing mechanisms pressing together a paint container and a cover. Each of the pressing mechanisms comprises: a through hole on the cover; a pressing rod passing through the through hole; a sealing sleeve sleeved over the pressing rod, and comprising a sealing sleeve folded edge pressing on the cover; a compression spring sleeved over the pressing rod between the sealing sleeve folded edge of the sealing sleeve and a handle at the upper end of the pressing rod; and a pressing foot located at the lower end of the pressing rod. The handle at the upper end of the pressing rod is a cam lifting handle comprising the upper end of the pressing rod and a cam hinged thereto. A cam surface of the cam lifting handle is in contact with an upper surface of a cam base. The cam base is a movable sleeve sleeved around the pressing rod. A movable sleeve folded edge is provided on the movable sleeve. An upper end of the compression spring presses against said folded edge of the movable sleeve.

摘要： A control valve includes a valve body and a valve element disposed in the valve body. The valve body is provided with a large pump inlet-outlet opening, a small pump inlet-outlet opening, a colorant bucket inlet-outlet opening and a colorant dispensing outlet. The valve core, which is provided with a passage, is rotated to allow connection of the large pump inlet-outlet opening and the small pump inlet-outlet opening with a colorant bucket or dispensing thereof, with at least three connecting structures being involved. The control valve is compact in structure and ingenious in design, and may fully achieve the objective of dispensing of large amount colorant or a small amount colorant by rotating the valve core; moreover, the objectives of cleaning the pump and preventing colorant drying and hardening in a colorant circulating pipe and a colorant outlet may be achieved.

摘要： In order to solve the problem of great abrasion of pistons and cylinder bores of a high-efficiency color-paste color-mixing pump, the invention provides a high-efficiency color-paste color-mixing pump with little abrasion of plunger pistons and cylinder bores, comprising cylinder bodies arranged around the circumference of a shaft and the plunger pistons matched with the cylinder bodies, wherein the cylinder bodies and the plunger pistons are sealed in a swelling, hard and fitted manner, that is, sealing elements between the cylinder bodies and the plunger pistons are sealing elements swelling towards the plunger pistons, and contact parts between the plunger pistons and the sealing elements are made of a hard material. Because in the high-efficiency color-paste color-mixing pump, a rolling friction pair of a roller and a swash-plate is used which is an improvement over a sliding friction pair of a slipper and a swash-plate of a swash-plate axial plunger piston pump, the friction force is greatly reduced, and thus the rolling friction force of the roller and the swash-plate of the high-efficiency color-paste color-mixing pump has very little impact on stress of the plunger pistons; and in addition, the roller and the swash-plate adopt the rolling friction pair, the stress of the plunger pistons is relatively simple, and the abradability of the contact parts between the plunger pistons and the sealing elements can be increased by increasing the hardness.
