Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a release agent uniform coating device. Background Technology

[0002] In many industrial production processes, the application of release agents is an important step. For example, in the production of plastic and rubber products, the uniform application of release agents can effectively prevent the products from sticking to the mold, thereby improving product quality and production efficiency.

[0003] In existing release agent coating equipment, most devices use traditional single-shaft stirring in the release agent mixing stage. This structure makes it difficult to fully mix the different components in the release agent, easily leading to uneven dispersion of additives and stratification of solvent and solute, thus affecting the performance stability of the release agent. At the same time, due to the lack of an effective internal wall cleaning mechanism, high-viscosity release agent is prone to residue accumulation on the inner wall of the mixing tank, which not only wastes materials but also contaminates subsequent batches of release agent, resulting in inconsistent product quality between different batches and failing to meet the strict requirements of high-precision production for release agent consistency. Therefore, we propose a release agent uniform coating device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a release agent uniform coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A release agent uniform coating device includes: a base plate; a frame, a coating tank, and a support frame are fixedly mounted on the top of the base plate; a mixing tank is fixedly mounted inside the support frame; a feeding valve pipe is connected to the bottom of the mixing tank; the outlet of the feeding valve pipe is connected to one side of the coating tank; a top cover is detachably mounted on the top of the mixing tank; two sets of feed pipes are connected to the top of the top cover; a frame is fixedly mounted on the top of the top cover; a motor is fixedly mounted on one side of the frame; a drive bevel gear is fixedly mounted on the output end of the motor; and a mixing sleeve shaft and a mixing shaft are rotatably mounted inside the top cover. A driven bevel gear one is fixedly installed on the top of the stirring shaft, and a driven bevel gear two is fixedly installed on the outer side of the top of the stirring sleeve shaft. Multiple sets of L-shaped scrapers are fixedly installed on the outer side of the bottom of the stirring shaft sleeve. Stirring blades are provided on the inner side of the multiple sets of L-shaped scrapers and the outer side of the stirring shaft. Two sets of screws are rotatably installed on the top of the frame. Threaded sleeves are threadedly connected to the outer side of the two sets of screws. Roller frames are fixedly installed at the bottom of the two sets of threaded sleeves. Pressure rollers are hinged inside the roller frames. A rubber layer is provided on the outer side of the pressure rollers. A paint roller is rotatably installed inside the frame. The outer side of the bottom of the paint roller is located inside the paint tank.

[0006] Preferably, two sets of brackets are fixedly installed on the top of the frame, and a rotating shaft is rotatably installed inside the two sets of brackets. Two sets of worm gears are fixedly installed on the outer side of each rotating shaft, and a worm wheel is fixedly installed on the top of each set of screws. A motor three is fixedly installed on one side of one set of brackets, and one end of the rotating shaft is fixedly installed on the output end of the motor three. A motor two is fixedly installed on one side of the frame, and one end of the paint roller is fixedly installed on the output end of the motor two.

[0007] Preferably, two sets of limiting rods are slidably mounted on the top of the frame, and the bottom of the two sets of limiting rods are fixedly mounted on the top of the roller frame.

[0008] Preferably, the stirring sleeve shaft is rotatably mounted on the outside of the stirring shaft, and multiple sets of L-shaped scrapers abut against the inner wall of the stirring tank.

[0009] Preferably, the driving bevel gear meshes with driven bevel gear one and driven bevel gear two, the driven bevel gear one is rotatably mounted on the top inner wall of the frame, and the driving bevel gear, driven bevel gear one and driven bevel gear two are all disposed within the frame.

[0010] Preferably, the two sets of worm gears mesh with the corresponding worm wheels.

[0011] In this invention, a release agent uniform coating device is described. It utilizes a three-drive motor shaft and worm gear rotation. The meshing of the worm wheel and worm gear drives two sets of worm wheels to synchronously rotate the screw. This causes the threaded sleeve to move the roller frame up and down under the constraint of a limit rod. This movement moves the roller frame, pressure roller, and rubber layer closer to or away from the coating roller. The rubber layer on the outer side of the pressure roller provides elastic contact and increases friction. This, in turn, activates a second-drive motor to rotate the coating roller, whose bottom is immersed in the coating tank to pick up the release agent. The workpiece to be coated passes between the coating roller and the pressure roller. The coating roller uniformly coats the workpiece surface with the release agent, meeting the high-precision requirements for release agent thickness for different products, improving product quality consistency, greatly expanding the scope of application, reducing the cost of replacing equipment due to changes in product specifications, and improving the equipment's versatility and utilization rate. This utility model features a reasonable structural design. A motor drives a primary bevel gear to rotate. This primary bevel gear meshes with two driven bevel gears, causing them to rotate in opposite directions. Driven bevel gear one drives the stirring shaft, while driven bevel gear two drives the stirring sleeve shaft and L-shaped scraper. The L-shaped scraper sweeps away material from the edges of the mixing tank to prevent residue. The stirring blades on the outside of the stirring shaft and the inner wall of the L-shaped scraper rotate alternately, providing bidirectional stirring of the release agent raw materials. This results in a more uniform mixture, preventing sedimentation. The uniformly mixed release agent flows into the coating tank through a feeding valve, quickly and thoroughly breaking up any agglomeration or stratification of the components, ensuring complete integration and significantly improving mixing uniformity. This guarantees stable release agent quality and prevents material residue from contaminating subsequent batches, ensuring the purity of each batch. The stable mixing effect ensures consistent release agent quality, providing a reliable guarantee for subsequent coating processes. This design is particularly suitable for continuous and automated production lines. Attached Figure Description
