Description

Technical Field

[0001] This utility model belongs to the technical field of coating processing equipment, and more specifically, it relates to a coating raw material grinding and feeding structure. Background Technology

[0002] In some paint coating production processes, sanders are used to grind large particles of solute, making the coating finer. Sanders use high-speed shearing to grind the coating through stirring. For example, utility model patent CN219942959U discloses an art paint sander, which includes a support shell, a collection tank, a horizontal grinding cylinder, and a two-stage grinding roller. The horizontal grinding cylinder makes the raw material move slowly and does not generate eddy currents, allowing the paint raw material to be fully ground. However, the paint raw material needs to be continuously added to the feed inlet, which requires manual control of the addition of raw material. This is not conducive to continuous production when processing large amounts of raw material.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a coating raw material grinding and feeding structure in order to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a coating raw material grinding and feeding structure to solve the problem of inconvenient continuous feeding of raw materials during coating grinding.

[0005] The purpose and effect of this utility model's coating raw material grinding and feeding structure are achieved by the following specific technical means:

[0006] A coating raw material grinding and feeding structure includes a grinding cylinder, which is divided into a feeding chamber and a grinding chamber by a partition. The feeding chamber of the grinding cylinder is provided with a feeding port that communicates with the grinding chamber. A feeding funnel is provided on the feeding port. A plug is slidably disposed in the feeding funnel. The plug is rhomboid in shape and is controlled by a reciprocating lifting mechanism to block the feeding port.

[0007] Furthermore, the reciprocating lifting mechanism includes a mounting cover provided on one side of the feeding funnel, a transmission rod passing through the mounting cover, a turntable provided at one end of the transmission rod, a telescopic rod sleeved on the eccentric shaft of the turntable, a guide shaft provided on one side of the plug, and the other end of the telescopic rod sleeved on the guide shaft. The transmission rod is connected to the grinding shaft inside the grinding cylinder through a linkage mechanism.

[0008] Furthermore, the inner rod of the telescopic rod is connected to the rod sleeve by a spring.

[0009] Furthermore, the linkage mechanism includes a driven wheel mounted on the transmission rod, and one end of the grinding shaft extends out of the grinding cylinder and is connected to a driving wheel. The driving wheel and the driven wheel are connected by a belt.

[0010] Furthermore, the mounting cover has an opening at the bottom, and the grinding cylinder has a movable groove corresponding to the feed chamber area, through which the telescopic rod passes and connects to the guide shaft.

[0011] Furthermore, the feed hopper has movable grooves on both sides, and the plug has sliders on both sides that are engaged in the corresponding movable grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using the plug, all the raw materials to be processed can be put into the feed funnel, which can widen the feeding area. The diamond-shaped design of the plug can guide the raw materials to slide down to both sides. During the reciprocating lifting and lowering of the plug, the feed port opens and closes regularly, so that the raw materials can enter the grinding cylinder continuously and evenly.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a coating raw material grinding and feeding structure, including a grinding cylinder 1. The grinding cylinder 1 is divided into a feeding chamber and a grinding chamber by a partition 102. A grinding shaft 3 is inserted into the grinding cylinder 1. A grinding roller is installed on the grinding shaft 3 in the grinding chamber. When the grinding roller rotates, it performs high-speed stirring, shearing and grinding on the raw material in the grinding chamber.

[0026] The grinding cylinder 1 has a feed inlet 101 communicating with the grinding chamber, and a feed funnel 2 is provided on the feed inlet 101. Figure 4 As shown, the feed inlet 101 is inclined internally, which guides the raw material into the grinding chamber, such as... Figure 3 As shown, a blocker 7 is slidably installed inside the feed hopper 2. The blocker 7 is rhomboid in shape. When the blocker 7 moves upward, the feed inlet 101 opens. The rhomboid shape allows the blocker 7 to guide the raw material to slide down to both sides and into the feed inlet 101, thereby entering the grinding chamber.

[0027] like Figure 2 As shown, the feed hopper 2 has movable grooves 703 on both sides, and the plug 7 has sliders 702 on both sides that are locked in the corresponding movable grooves 703. The plug 7 can slide up and down by following the movable grooves 703 through the sliders 702.

[0028] The blocking body 7 is controlled by a reciprocating lifting mechanism to block the feed inlet 101. During the continuous reciprocating lifting of the blocking body 7, the raw material can continuously and evenly enter the grinding cylinder 1. Figure 2 As shown, the reciprocating lifting mechanism includes a mounting cover 202 provided on one side of the feeding hopper 2, a transmission rod 201 passing through the mounting cover 202, a turntable 203 provided at one end of the transmission rod 201, a telescopic rod 204 sleeved on the eccentric shaft of the turntable 203, a guide shaft 701 provided on one side of the plug body 7, and the other end of the telescopic rod 204 sleeved on the guide shaft 701. When the transmission rod 201 rotates, it drives the turntable 203 to rotate, and the eccentric shaft on the turntable 203 causes the telescopic rod 204 to drive the plug body 7 to perform reciprocating lifting motion, thereby realizing the continuous opening and closing of the feeding port 101.

[0029] The telescopic rod 204 ensures that the plug 7 remains closed as the eccentric shaft on the turntable 203 enters the lower semicircular area from the middle position. Only after the eccentric shaft enters the upper semicircular area and the telescopic rod 204 extends to a certain length will the plug 7 move upward, allowing intermittent and uniform feeding at the feed inlet 101. In this embodiment, the inner rod and the sleeve of the telescopic rod 204 are connected by a spring, increasing the rebound speed of the telescopic rod 204 after compression and extension. This also prevents the plug 7 from failing to seal the feed inlet 101 when the eccentric shaft just enters the lower semicircular area due to its small weight.

[0030] The mounting cover 202 has an opening at the bottom, and the grinding cylinder 1 has a movable groove 704 in the area corresponding to the feeding chamber. The telescopic rod 204 passes through the movable groove 704 and is connected to the guide shaft 701. The movable groove 704 is a reserved space for the swing of the telescopic rod 204.

[0031] In addition, the transmission rod 201 is connected to the grinding shaft 3 inside the grinding cylinder 1 through a linkage mechanism. The linkage mechanism includes a driven wheel 6 set on the transmission rod 201. One end of the grinding shaft 3 passes through the grinding cylinder 1 and is connected to the driving wheel 4. The driving wheel 4 and the driven wheel 6 are connected by a belt 5, so that feeding and grinding are carried out at the same time, saving the transmission source and making grinding and feeding work together, which is suitable for grinding and processing of paint in assembly line production.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
