Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixing device for processing raw materials of TPE thermoplastic elastomer material. Background Technology

[0002] Thermoplastic elastomer (TPE) is a polymer material that combines the processability of thermoplastics with the high elasticity of traditional vulcanized rubber. TPE is composed of a mixture of various raw materials.

[0003] Existing mixing equipment uses a motor to drive the mixing components to rotate, thereby mixing the internal raw materials. The mixing components are designed to be in a fixed position, and the mixing components and the inner wall of the mixing tank are spaced apart. After mixing, the TPE processing raw materials tend to adhere to the inner wall of the mixing tank. The residual raw materials not only cause material waste, but also require operators to manually clean the tank wall, increasing the labor burden on personnel. Summary of the Invention

[0004] This utility model provides a mixing device for processing TPE thermoplastic elastomer materials. After the raw materials are mixed, the axial movement of the inner moving shaft causes the outer stirring rod and the tail radial scraper to move and adhere to the inner wall of the main mixing tank. The outer stirring rod and the tail radial scraper accelerate the discharge of the raw materials and clean the raw materials adhering to the inner wall of the main mixing tank, thereby reducing the residue of raw materials and reducing the cleaning burden on personnel.

[0005] This utility model provides a mixing device for processing raw materials of TPE thermoplastic elastomer material, specifically including a main mixing tank, an inner mixing shaft and an inner moving shaft. The inner mixing shaft is rotatably connected to the inner side of the main mixing tank, and the inner moving shaft is axially slidably connected to the inner side of the inner mixing shaft and sealed with a rubber ring. The outer side of the inner mixing shaft is provided with radially sliding outer mixing rods arranged in an annular array and sealed with rubber rings at the sliding positions. The middle part of the inner mixing shaft is provided with a central sliding groove arranged in an annular array. The tail end of the inner mixing shaft is axially slidably connected to a tail radial scraper, and the tail radial scraper and the tail end of the central synchronous connecting rod are fixedly connected.

[0006] Furthermore, the upper part of the main mixing tank is hinged with an upper cover plate, and a drive motor and a side telescopic cylinder are fixedly connected to both sides of the main mixing tank respectively. The bottom of the main mixing tank is connected to a lower discharge port, and the outer mixing rod and the tail radial scraper are both provided with rubber layers and elastically fit against the inner wall of the main mixing tank.

[0007] Furthermore, the outer stirring rod and the tail radial scraper are both located inside the main mixing tank, and the outer stirring rod and the tail radial scraper are fitted with rubber to fit the inner wall of the main mixing tank. The main shaft of the drive motor and the inner stirring shaft are fixedly connected.

[0008] An outer connecting block is fixed to the outer ring array of the inner moving shaft. The outer connecting block and the first end of the outer support rod are rotatably connected. The first end of the inner moving shaft is circumferentially rotatably connected to the first connecting frame.

[0009] Furthermore, the telescopic rod of the side telescopic cylinder is fixedly connected to the first connecting rotating frame, and the tail end of the outer support rod is rotatably connected to the outer stirring rod. The outer support rod supports the outer stirring rod to move radially, so that the outer stirring rod is away from the inner wall of the main stirring tank.

[0010] Furthermore, the outer connecting block is disposed inside the middle sliding groove, and the outer connecting block and the first end of the middle synchronous connecting rod are fixedly connected. The inner moving shaft drives the tail radial scraper to move synchronously axially through the middle synchronous connecting rod.

[0011] Furthermore, when the outer connecting block moves axially along the central chute, the outer stirring rod moves radially and the tail radial scraper moves axially. The outer stirring rod and the tail radial scraper simultaneously adhere to the inner wall of the main mixing tank to accelerate the discharge of the main mixing tank. At the same time, the TPE thermoplastic elastomer processing raw materials attached to the inner wall of the main mixing tank are scraped off simultaneously to reduce the amount of raw materials adhering to the tank wall of the main mixing tank.

[0012] This utility model provides a mixing device for processing raw materials of TPE thermoplastic elastomer materials, which has the following beneficial effects:

[0013] After the raw materials are mixed, the axial movement of the inner moving shaft causes the outer stirring rod and the tail radial scraper to move and adhere to the inner wall of the main mixing tank. The outer stirring rod and the tail radial scraper accelerate the discharge of the raw materials and clean the processed raw materials adhering to the inner wall of the main mixing tank, reducing the raw material residue on the inner wall of the main mixing tank and reducing the cleaning burden on personnel.

[0014] When the raw materials are being mixed, the outer stirring rod and the tail radial scraper are kept away from the inner wall of the main mixing tank. This reduces the wear and tear caused by the contact between the outer stirring rod, the tail radial scraper and the inner wall of the main mixing tank, and avoids deformation and scratch damage of the parts due to long-term contact friction, thus extending their service life.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a mixing device for processing TPE thermoplastic elastomer materials, including a main mixing tank 1, an inner mixing shaft 2, and an inner moving shaft 3. An upper cover plate 101 is hinged to the upper part of the main mixing tank 1. A drive motor 102 and a side telescopic cylinder 104 are fixedly connected to both sides of the main mixing tank 1, respectively. A lower discharge port 103 is connected to the bottom of the main mixing tank 1. Both the outer mixing rod 201 and the tail radial scraper 203 are provided with rubber layers and elastically fit against the inner wall of the main mixing tank 1. The inner mixing shaft 2 is rotatably connected to the inner side of the main mixing tank 1. Radial sliding outer mixing rods 201 are arranged in a circular array on the outer side of the inner mixing shaft 2, and rubber rings are provided at the sliding positions. The inner stirring shaft 2 has a central sliding groove 202 arranged in a ring array in the middle. A tail radial scraper 203 is axially slidably connected to the tail end of the inner stirring shaft 2. The tail radial scraper 203 is fixedly connected to the tail end of the central synchronous connecting rod 204. Both the outer stirring rod 201 and the tail radial scraper 203 are located inside the main stirring tank 1. The outer stirring rod 201 and the tail radial scraper 203 are rubber-fitted against the inner wall of the main stirring tank 1. The outer stirring rod 201 and the tail radial scraper 203 move away from the inner wall of the main stirring tank 1 synchronously, avoiding continuous contact and friction between the outer stirring rod 201 and the tail radial scraper 203 and the inner wall of the main stirring tank 1 during the stirring process, thus reducing the friction caused by the outer stirring rod 201 and the tail radial scraper 203. Friction loss of plate 203 and inner wall of main mixing tank 1; the main shaft of drive motor 102 and inner mixing shaft 2 are fixedly connected; inner moving shaft 3 is axially slidably connected to the inner side of inner mixing shaft 2 and sealed with rubber ring; outer connecting block 301 is fixed in an annular array on the outer side of inner moving shaft 3; outer connecting block 301 and the first end of outer support rod 302 are rotatably connected; the first end of inner moving shaft 3 is circumferentially rotatably connected to first connecting frame 303; the telescopic rod of side telescopic cylinder 104 supports the first connecting frame 303 and inner moving shaft 3 to move axially synchronously, realizing the position adjustment of inner moving shaft 3 and outer support rod 302, realizing the connection between outer mixing rod 201 and tail radial scraper 20 The position of 3 changes, the telescopic rod of the first connecting frame 303 and the side telescopic cylinder 104 is rotatably connected, the tail end of the outer support rod 302 is rotatably connected to the outer stirring rod 201, the outer support rod 302 supports the outer stirring rod 201 to move radially, so that the outer stirring rod 201 is away from the inner wall of the main mixing tank 1, the outer connecting block 301 is set inside the middle sliding groove 202, and the inner sliding groove 202 is provided with a sealing rubber ring to fit the inner moving shaft 3, so as to achieve the sealing work between the middle sliding groove 202 and the inner moving shaft 3. The outer connecting block 301 and the first end of the middle synchronous connecting rod 204 are fixedly connected, and the inner moving shaft 3 drives the tail radial scraper 203 to move synchronously axially through the middle synchronous connecting rod 204.

[0031] In this embodiment, when the outer connecting block 301 moves axially along the middle sliding groove 202, the outer stirring rod 201 moves radially and the tail radial scraper 203 moves axially. The outer stirring rod 201 and the tail radial scraper 203 simultaneously adhere to the inner wall of the main mixing tank 1 to accelerate the discharge of the main mixing tank 1. At the same time, the TPE thermoplastic elastomer processing raw material attached to the inner wall of the main mixing tank 1 is simultaneously scraped off to reduce the amount of raw material adhering to the tank wall of the main mixing tank 1.

[0032] In this second embodiment, based on the first embodiment, both the inner stirring shaft 2 and the inner moving shaft 3 in the vertical mixing device are changed to be vertical, so as to meet the compatibility of use in the vertical mixing device and realize the compatibility of vertical mixing and horizontal mixing.

[0033] The working principle of this embodiment is as follows: When the upper cover plate 101 is opened, the main mixing tank 1 is filled with raw materials. When the upper cover plate 101 is closed, the main mixing tank 1 is sealed. The drive motor 102 drives the inner stirring shaft 2 to rotate. The inner stirring shaft 2, the outer stirring rod 201, and the inner moving shaft 3 all rotate synchronously. The outer stirring rod 201 stirs and mixes the raw materials inside the main mixing tank 1. The lower discharge port 103 discharges the material after stirring. Before the stirring operation, when the outer connecting block 301 moves axially along the middle sliding groove 202, the outer support rod 302 drives the outer stirring rod 201 synchronously. The outer stirring rod 201 moves radially and drives the tail radial scraper 203 to move axially synchronously through the middle synchronous connecting rod 204, so that the outer stirring rod 201 and the tail radial scraper 203 move away from the inner wall of the main stirring tank 1 synchronously. This avoids the outer stirring rod 201 and the tail radial scraper 203 from continuously contacting and rubbing against the inner wall of the main stirring tank 1 during the stirring process, reduces the friction loss and component wear of the outer stirring rod 201, the tail radial scraper 203 and the inner wall of the main stirring tank 1, reduces component deformation and scratch damage caused by long-term contact and friction, significantly extends the overall service life of the stirring device, and reduces equipment maintenance and replacement costs.

[0034] The inner moving shaft 3 slides axially along the inner stirring shaft 2, causing the outer stirring rod 201 to extend radially synchronously, and the tail radial scraper 203 to slide axially synchronously. This allows the outer stirring rod 201 and the tail radial scraper 203 to simultaneously adhere to the inner wall of the main mixing tank 1, thereby simultaneously scraping and cleaning the TPE thermoplastic elastomer processing raw materials adhering to the inner wall of the main mixing tank 1. This reduces material residue caused by the material adhering to the tank wall of the main mixing tank 1, while also accelerating the discharge of materials from the main mixing tank 1, improving discharge efficiency, reducing subsequent manual cleaning work, and reducing the labor load of operators cleaning the inner wall of the main mixing tank 1.
