Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and in particular to a thermoplastic elastomer mixing device that is easy to clean. Background Technology

[0002] Thermoplastic elastomers (TPEs), as polymer materials that combine the elasticity of rubber with the processing properties of plastics, are widely used in automotive manufacturing, electronics, medical devices, and other fields. In the TPE production process, mixing is a key step to ensure uniform material mixing and improve product quality.

[0003] A search revealed a discharge plate for the production of thermoplastic elastomers (publication number CN212636204U) that is easy to clean. The plate includes a mixing tank, with a discharge pipe fixedly installed on the left side of the top of the mixing tank. An active rod is rotatably connected inside the mixing tank, with its top penetrating and rotatably connected to the top of the mixing tank. An electric motor is installed on the top of the mixing tank. This invention utilizes the electric motor to drive the active rod, causing the discharge pipe to rotate in the opposite direction. This, in turn, causes the mixing blades on both sides of the active rod to work in conjunction with the driven blades on both sides of the discharge pipe, resulting in better mixing. The discharge pipe can also drive cleaning scrapers, preventing residue buildup on the inner wall of the mixing tank after mixing and discharge. The active rod can also drive an anti-blocking rod, preventing material residue from remaining in the discharge pipe and reducing the likelihood of blockage during discharge. Furthermore, anti-residue scrapers are installed on both sides of the anti-blocking rod to scrape away any remaining material on the inner wall of the discharge pipe, minimizing residue buildup within the device.

[0004] Based on the aforementioned patents, the inside of the mixing tank is cleaned by a scraper. However, when cleaning the inner wall of the tank by a scraper, the cleaning effect is poor, and the above devices are not convenient for cleaning the drive rod and stirring blades. In view of this technical problem, this application proposes a thermoplastic elastomer mixing device that is easy to clean. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of using scrapers to clean the inner wall of a tank, which result in poor cleaning efficiency and make it inconvenient to clean the drive rod and stirring blades. This invention proposes a thermoplastic elastomer stirring device that facilitates cleaning. By moving the stirring plate up and down while stirring, the material is more thoroughly mixed, improving the uniformity and quality of the mixing. Furthermore, the hydraulic rod moves the top cover upwards, facilitating the cleaning of the inside of the mixing tank and the stirring plate, thus improving cleaning efficiency and shortening cleaning time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermoplastic elastomer mixing device that is easy to clean, comprising a mixing tank, a top cover provided at the top of the mixing tank, a support wall fixedly connected to the top of the top cover, a rotating shaft rotatably connected to the inner wall of the support wall, the rotating shaft being connected to a moving block via a reciprocating assembly, the outer wall of the moving block being slidably connected to the inner wall of the support wall, a connecting shaft rotatably connected to the inner wall of the moving block, the connecting shaft being connected to a mixing plate via a rotating assembly, and support blocks fixedly connected to both sides of the outer wall of the mixing tank, the support blocks being connected to the top cover via a lifting assembly.

[0007] Furthermore, the reciprocating assembly includes a half gear fixedly connected to the rear end of the rotating shaft, the outer wall of the half gear being meshed with an internal gear plate, and the outer wall of the internal gear plate being fixedly connected to the inner wall of the moving block.

[0008] Furthermore, a motor is fixedly connected to the front end of the support wall, and the front end of the rotating shaft is fixedly connected to the motor drive end.

[0009] Furthermore, the rotating assembly includes a first bevel gear fixedly connected to the outer wall of the connecting shaft, a second bevel gear meshing with the outer wall of the first bevel gear, a rotating shaft fixedly connected to the bottom end of the second bevel gear, the outer wall of the rotating shaft rotatably connected to the inner wall of the moving block, and the inner sides of the stirring plates fixedly connected to the outer wall of the rotating shaft.

[0010] Furthermore, a drive gear is fixedly connected to the outer wall of the connecting shaft, and a drive gear plate is meshed with the outer wall of the drive gear. The right end of the drive gear plate is fixedly connected to the inner wall of the support wall.

[0011] Furthermore, the lifting assembly includes a hydraulic rod fixedly connected to the top of the support block, a connecting block fixedly connected to the top of the hydraulic rod, and the other end of the connecting block fixedly connected to the outer wall of the top cover.

[0012] Furthermore, a connecting ring is fixedly connected to the bottom end of the top cover, and a slot is provided at the top of the mixing tank, with the connecting ring located on the inner wall of the slot.

[0013] Furthermore, a feed pipe is fixedly connected to the top of the top cover, and a discharge pipe is fixedly connected to the bottom of the mixing tank.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the motor drives the half gear to rotate, thereby causing the inner gear plate to move up and down, which in turn drives the moving block to move up and down. When the moving block moves, the internal drive gear moves on the drive gear plate, thereby causing the rotating shaft to move and rotate at the same time. This, in turn, drives the stirring plate to move up and down while stirring, so that the material can be more fully stirred and mixed, improving the uniformity and quality of stirring.

[0016] 2. In this utility model, the top cover is moved upward by a hydraulic rod to open the top cover, which in turn moves the mixing plate out, thereby facilitating the cleaning of the inside of the mixing tank and the mixing plate, improving cleaning efficiency and shortening cleaning time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3This utility model provides an embodiment of a thermoplastic elastomer mixing device that is easy to clean. It includes a mixing tank 1, a top cover 2 at the top of the mixing tank 1, a support wall 3 fixedly connected to the top of the top cover 2, a rotating shaft 5 rotatably connected to the inner wall of the support wall 3, a half gear 6 fixedly connected to the rear end of the rotating shaft 5, an internal gear plate 7 meshing with the outer wall of the half gear 6, and the outer wall of the internal gear plate 7 fixedly connected to the inner wall of a moving block 8. A motor 4 is fixedly connected to the front end of the support wall 3, and the front end of the rotating shaft 5 is fixedly connected to the drive end of the motor 4. The outer wall of the moving block 8 is slidably connected to the inner wall of the support wall 3, and a connecting shaft 11 rotatably connects to the inner wall of the moving block 8. A first bevel gear 12 is fixedly connected to the outer wall of the connecting shaft 11, a second bevel gear 13 meshing with the outer wall of the first bevel gear 12, a rotating shaft 14 fixedly connected to the bottom end of the second bevel gear 13, and the outer wall of the rotating shaft 14 rotatably connected to the inner wall of the moving block 8. The inner sides of the mixing plates 15 are all fixedly connected to the outer wall of the rotating shaft 14. (See reference...) Figure 4 A drive gear 10 is fixedly connected to the outer wall of the connecting shaft 11, and a drive gear plate 9 is meshed with the outer wall of the drive gear 10. The right end of the drive gear plate 9 is fixedly connected to the inner wall of the support wall 3.

[0026] Specifically, when the half gear 6 rotates on the inner wall of the inner gear plate 7, it can cause the inner gear plate 7 to move up and down. The inner gear plate 7 can then drive the moving block 8 to move up and down. When the moving block 8 causes the drive gear 10 to move one stroke on the drive gear plate 9, it will cause the rotating shaft 14 to rotate multiple times in one direction before rotating in the opposite direction.

[0027] Reference Figure 5 Support blocks 16 are fixedly connected to both sides of the outer wall of the mixing tank 1. A hydraulic rod 17 is fixedly connected to the top of the support block 16. A connecting block 18 is fixedly connected to the top of the hydraulic rod 17. The other end of the connecting block 18 is fixedly connected to the outer wall of the top cover 2. A connecting ring 19 is fixedly connected to the bottom of the top cover 2. A slot 20 is opened at the top of the mixing tank 1. The connecting ring 19 is located on the inner wall of the slot 20. A feed pipe 21 is fixedly connected to the top of the top cover 2. A discharge pipe 22 is fixedly connected to the bottom of the mixing tank 1.

[0028] Specifically, when the top cover 2 is placed on top of the mixing tank 1, the connecting ring 19 at the bottom of the top cover 2 will enter the slot 20, making the connection between the top cover 2 and the mixing tank 1 more stable, so that the top cover 2 will not shake when the mixing plate 15 rotates. The bottom of the mixing tank 1 is conical to facilitate the flow of materials, and a control valve is installed on the discharge pipe 22.

[0029] Working principle: During use, materials are added into the mixing tank 1 through the feed pipe 21. The motor 4 is started, driving the rotating shaft 5 to rotate. The rotating shaft 5 then drives the half gear 6 to rotate, causing the internal gear plate 7 to move up and down. The internal gear plate 7 causes the moving block 8 to move up and down, which in turn drives the rotating shaft 14 to move up and down, thus causing the mixing plate 15 to move up and down. Simultaneously, the movement of the moving block 8 causes the internal drive gear 10 to move on the drive gear plate 9, causing the drive gear 10 to rotate and drive the connecting shaft 11 to rotate. The connecting shaft 11 then drives the first bevel gear 13 to rotate. The second bevel gear 13 rotates, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 then drives the mixing plate 15 to rotate, thus mixing the internal material. After mixing, the material exits through the discharge pipe 22 at the bottom. When cleaning the inside of the mixing tank 1, the hydraulic rods 17 on both sides can be activated. The hydraulic rods 17 drive the connecting block 18 to move upward, which in turn drives the top cover 2 to move upward. The top cover 2 then drives the rotating shaft 14 and the mixing plate 15 to move out of the mixing tank 1, making it easier for workers to clean the inside of the mixing tank 1 and to clean the mixing plate 15.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
