Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, and more specifically, to a device for extruding powder coatings. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, powder coatings use air as the dispersion medium and have the characteristics of no solvent pollution and low energy consumption. During the processing of powder coatings, various raw materials are mixed and melted, and then extruded through extrusion equipment into collection and storage equipment or extruded onto a finishing platform.

[0003] Based on the above, the inventors have discovered that existing extrusion equipment suffers from poor mixing and melting effects due to the different specifications of raw materials and the potential clumping caused by humidity, temperature, static electricity, etc., which affects the quality of subsequent coatings. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a powder coating extrusion device with greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a device for extruding powder coatings. This solution is equipped with a grinding component, which can crush and grind the coating raw materials, reduce the problem of raw material agglomeration or uneven size, and improve the effect of subsequent hot melt extrusion of the raw materials. In addition, an adjustment component is provided to adjust the position of the feeding component, ensuring uniform feeding and improving the effect of raw material grinding and crushing.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

A material equalization mechanism is provided above the opposite surfaces of the two material gathering plates, and a toothed ring is fixedly connected to one end of each grinding roller.

[0009] The material feeding mechanism includes a drive motor, the output end of which is fixedly connected to a reciprocating lead screw, a ball bearing slider is sleeved on the outside of the reciprocating lead screw, and a feeding pipe is fixedly connected to one side of the ball bearing slider.

[0010] Furthermore, the bottom of the processing tank is provided with a discharge port, which is connected to the rear end of the screw extruder near the top.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution sets up two transmission rings in conjunction with toothed belts, so that the rotation of the reciprocating screw drives the corresponding grinding roller to rotate. At the same time, with the cooperation of the two meshing toothed rings, the other grinding roller rotates in the opposite direction to crush the raw material. Compared with the existing technology, the grinding component can crush and grind the coating raw material, reduce the problem of raw material agglomeration or uneven size, and improve the effect of subsequent hot melt extrusion of the raw material.

[0019] (2) By setting up a material equalization mechanism, the raw material is conveyed by the feeding pipe and the material gathering plate is used to gather the raw material, so that it can enter the two grinding rollers better. During the feeding process, the reciprocating screw rotates, causing the ball slider to drive the feeding pipe to move back and forth, ensuring the uniformity of feeding. Compared with the existing technology, the setting of the adjustment component can adjust the position of the feeding component, ensure the uniformity of feeding, and improve the effect of raw material grinding and crushing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A powder coating extrusion device includes a base 1, a screw extruder 2 fixedly connected to the front end of the top of the base 1, a processing tank 3 fixedly connected to the upper rear end of the screw extruder 2, a feed inlet 4 opened at the top of the processing tank 3, a pair of material gathering plates 5 fixedly connected in the center of the interior of the processing tank 3, and a pair of grinding rollers 7 movably connected to the lower interior of the processing tank 3, a material equalization mechanism 6 is provided on the upper side of the opposite surface of the two material gathering plates 5, and a toothed ring 8 is fixedly connected to one end of each grinding roller 7;

[0028] The material equalization mechanism 6 includes a drive motor 11, and a reciprocating screw 12 is fixedly connected to the output end of the drive motor 11. A ball bearing slider 13 is sleeved on the outside of the reciprocating screw 12, and a feeding pipe 14 is fixedly connected to one side of the ball bearing slider 13. The material equalization mechanism 6 is provided in order to ensure the uniformity of feeding and improve the crushing effect.

[0029] See Figure 1 The bottom of the processing tank 3 is provided with a discharge port, which is connected to the rear end of the screw extruder 2 near the top. The crushed raw material is fed into the screw extruder 2 through the discharge port for hot melting processing, and then extruded from the output end of the screw extruder 2.

[0030] See Figure 2 The material gathering plate 5 is set at an angle, and the gap between the two material gathering plates 5 is located directly above the two grinding rollers 7. The two toothed rings 8 are meshed and connected. The material gathering plate 5 can gather the raw material and make it better enter the space between the two grinding rollers 7.

[0031] See Figure 2The drive motor 11 is fixedly connected to the outside of the processing tank 3, and the reciprocating screw 12 is movably connected to the top of the processing tank 3. The reciprocating screw 12 is located directly above one of the grinding rollers 7. The drive motor 11 is started to drive the reciprocating screw 12 to rotate, so that the ball slider 13 drives the feed tube 14 to move back and forth to ensure the uniformity of feeding.

[0032] See Figure 3 One end of the reciprocating screw 12 and the other end of the corresponding grinding roller 7 are fixedly connected to a transmission ring 9. A toothed belt 10 is sleeved on the outer side of the opposite face of the two transmission rings 9. The two transmission rings 9 cooperate with the toothed belt 10 to make the rotation of the reciprocating screw 12 drive the corresponding grinding roller 7 to rotate. At the same time, with the cooperation of the two meshing toothed rings 8, the other grinding roller 7 rotates in the opposite direction.

[0033] See Figure 4 A guide rod is provided through the top of the ball slider 13. The guide rod is fixedly connected to the processing tank 3, and the movement stability of the ball slider 13 is ensured by the guide rod.

[0034] See Figure 4 The feed pipe 14 is corrugated and the top of the feed pipe 14 is fixedly connected to the bottom of the feed inlet 4 to feed the raw material into the feed inlet 4 and then drop it into the processing tank 3 through the feed pipe 14.

[0035] In use: The raw material is fed into the feed inlet 4 and then falls into the processing tank 3 through the discharge pipe 14. The material gathering plate 5 gathers the raw material, allowing it to enter the space between the two grinding rollers 7 more effectively. During the feeding process, the drive motor 11 is started to drive the reciprocating screw 12 to rotate, causing the ball block slider 13 to drive the discharge pipe 14 to move back and forth, ensuring the uniformity of the feeding. The two transmission rings 9 cooperate with the toothed belt 10 to make the rotation of the reciprocating screw 12 drive the corresponding grinding roller 7 to rotate. At the same time, with the cooperation of the two meshing toothed rings 8, the other grinding roller 7 rotates in the opposite direction to crush the raw material. Then, the crushed raw material is fed into the screw extruder 2 through the discharge port for heat melting treatment, and finally extruded from the output end of the screw extruder 2.
