Description

Technical Field

[0001] This utility model relates to the field of putty powder production technology, specifically to a feeding device for putty powder production. Background Technology

[0002] Putty powder is a building material used to fill gaps in walls, smooth the wall surface, and enhance the adhesion of the wall surface. The raw materials of putty powder include gypsum, calcium carbonate, talc, mica, whitening agent, adhesive, etc. These raw materials are processed through multiple steps to finally produce putty powder.

[0003] According to a high-efficiency, non-destructive feeding device for putty powder production with application number 202323231802.7, a motor is added to facilitate the rotation of the stirring rod, which in turn drives the stirring blades to rotate. The rotation of the stirring blades breaks up the putty powder that has clumped due to moisture, making the subsequent mixing process easier and avoiding the impact of clumping on mixing efficiency and unnecessary damage to the user.

[0004] However, the aforementioned feeding device for putty powder production still has certain shortcomings. Although the device can break up damp, clump-forming putty powder, the putty powder itself still has a high moisture content, which affects the drying speed of the putty, keeping it in a damp state for a long time and increasing the risk of deterioration. The device cannot dry the putty powder after breaking it up, thus still having certain deficiencies. Therefore, we propose a feeding device for putty powder production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for putty powder production, which solves the problems mentioned in the background section.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a feeding device for putty powder production, including a box body 1. Two sets of conveying rollers 4 are rotatably installed inside the box body 1, with two conveying rollers 4 forming a set. A Teflon conveyor belt 5 is installed on the outside of the conveying rollers 4. Two first stepper motors 6 are fixedly installed on the outside of the box body 1. The output ends of the two first stepper motors 6 extend into the inside of the box body 1 and are fixedly connected to one end of the conveying rollers 4. Heating plates 7 are fixedly installed inside the box body 1 and on the inside of the two Teflon conveyor belts 5. Heating wires 8 are provided inside the heating plates 7. Several sleeves 9 are fixedly installed on the top inside the box body 1. Sliding rods 10 are slidably installed inside the bottom of the sleeves 9. An installation plate 11 is fixedly installed on one end of the sliding rod 10. Several rake rods 12 are fixedly installed on the bottom of the installation plate 11. The rake rods 12 cooperate with the Teflon conveyor belts 5. When the first step motor 6 drives one conveyor roller 4 to rotate, the Teflon conveyor belt 5 drives the other conveyor roller 4 to rotate simultaneously, thereby conveying the crushed putty powder. After the putty powder is crushed and fed onto the Teflon conveyor belt 5, it will accumulate and spread unevenly. Therefore, when the Teflon conveyor belt 5 is conveying the putty powder, the rake rod 12 can be used to rake and spread the accumulated putty powder evenly, thereby improving its subsequent drying efficiency and drying effect.

[0023] A feeding port 3 is provided on one side of the top of the box body 1. A feeding hopper 2 is fixedly installed on the top of the box body 1, above the feeding port 3. Two mounting shafts 15 are rotatably mounted inside the feeding hopper 2. Crushing rollers 16 are fixedly installed on the outer side of each of the two mounting shafts 15. The two crushing rollers 16 cooperate with each other. One end of each mounting shaft 15 extends to the outer side of the feeding hopper 2 and is fixedly mounted with a gear 18. The two gears 18 mesh with each other. A second stepper motor 19 is fixedly installed on the top of the outer side of the box body 1. The output end of the second stepper motor 19 is fixedly connected to one end of the mounting shaft 15. After the putty powder to be fed is added into the feeding hopper 2, the second stepper motor 19 is turned on, which drives one mounting shaft 15 and the gear 18 to rotate. When one gear 18 meshes with the other gear 18, it drives the other mounting shaft 15 to rotate, so that the two crushing rollers 16 rotate in opposite directions. This crushes the added putty powder from clumping, preventing lumps from being added into the box body 1.

[0024] A first guide block 17 is fixedly installed on both sides inside the feeding hopper 2 and above the two crushing rollers 16. The first guide block 17 guides the putty powder added to the feeding hopper 2, so that the putty powder can be conveyed to the middle of the two crushing rollers 16 for crushing.

[0025] A slide plate 13 is fixedly installed at the other end of the slide rod 10 and inside the sleeve 9. A spring 14 is installed inside the sleeve 9, and the slide plate 13 cooperates with the spring 14. The spring 14 presses down on the slide plate 13, thereby pushing the slide rod 10 and the rake rod 12 to always be pressed down and in contact with the top of the Teflon conveyor belt 5, ensuring that the rake rod 12 disperses the putty powder.

[0026] The inner walls on both sides of the box 1 are fixedly equipped with second guide blocks 20. The second guide blocks 20 can guide the putty powder added into the box 1 and guide the putty powder conveyed by the Teflon conveyor belt 5 to the Teflon conveyor belt 5 below for conveying.

[0027] Scrapers 22 are fixedly installed on the bottom of both sides inside the feeding hopper 2, and the scrapers 22 cooperate with the crushing roller 16. With the setting of the scrapers 22, when the crushing roller 16 rotates to squeeze and crush the damp and clumped putty powder, some putty powder will stick to the outside of the crushing roller 16. Thus, when the crushing roller 16 rotates, the scrapers 22 can scrape off the putty powder remaining on the outside of the crushing roller 16, ensuring that no putty powder sticks to the outside of the crushing roller 16.

[0028] The bottom of the box 1 is equipped with a discharge hopper 21. The pulverized and dried putty powder can be fed into the production process through the discharge hopper 21. Both sides of the box 1 are equipped with support legs, and the top of the support legs is equipped with a control box.

[0029] In summary, the feeding device for putty powder production operates by first activating the first stepper motor 6 and the second stepper motor 19 via the control box, and then energizing the heating wire 8. Once the second stepper motor 19 is activated, it drives a mounting shaft 15 and a gear 18 to rotate. The meshing of one gear 18 with the other gear 18 drives the other mounting shaft 15 to rotate, causing the two crushing rollers 16 to rotate in opposite directions. The putty powder to be processed is then added to the feeding hopper 2, and guided by the first guide block 17, it falls into the middle of the two crushing rollers 16, thus crushing any clumps. The putty powder is compressed and broken. The broken putty powder is added into the box 1 through the feeding port 3 and guided by the second guide block 20 so that it can fall accurately onto the Teflon conveyor belt 5. At the same time, the first step motor 6 is turned on and drives the conveyor roller 4 to rotate the Teflon conveyor belt 5. The added putty powder is conveyed through the Teflon conveyor belt 5. When it is conveyed to the bottom of the rake 12, the rake 12 will rake it and spread it evenly, so that it can be dried evenly by the heat generated by the heating wire 8. The dried putty powder is discharged through the discharge port at the bottom of the discharge hopper 21.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
