Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a mixing tank for processing TPE plastic granules. Background Technology

[0002] In the processing and production of plastic products, it is often necessary to mix colloidal particles of various materials according to the process requirements of the product. Before the plastic extrusion process, different plastic particles need to be stirred to make them uniformly mixed and improve the performance of the plastic material after production.

[0003] Publication number CN215396179U discloses a mixing tank for processing TPE plastic granules, including a cylindrical body. A feed pipe is fixedly provided on the side surface of the cylindrical body, a stirring motor is fixedly provided in the middle of the upper surface of the cylindrical body, a guide plate is fixedly provided on the inner wall of the cylindrical body, and a rotating shaft is fixedly provided on the output shaft of the stirring motor.

[0004] Although this device uses a stirring motor to drive a spiral mixing disc, and different plastic granules are added through the feed pipe, the plastic granules slide down through the guide plate to the inner ring opening. The rotating spiral mixing disc disrupts and mixes the falling plastic granules. The mixed plastic granules fall to the bottom of the inner wall of the cylinder. The rotating shaft drives the stirring rod and stirring plow to rotate clockwise. The stirring rod and connecting rod stir the raw materials, and multiple stirring plows rotate clockwise to plow and tumble the raw materials, making the raw materials more uniform and the stirring effect more ideal. However, the plastic granules pushed to the bottom of the device are not fully stirred. At the same time, during the stirring process, especially at high speed, the stirring tank may vibrate to a certain extent. The structural vibration will accelerate the wear of the stirring structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mixing tank for processing TPE plastic granules.

[0006] This utility model is achieved using the following technical solution: a mixing tank for processing TPE plastic granules, comprising a mixing tank, a feeding port fixedly connected to the top of the mixing tank, a sealing cover hinged to the top of the feeding port, a mounting frame hinged to the top of the mixing tank, a mixing mechanism provided on the inner wall of the mixing tank, a buffer mechanism provided on the surface of the mixing tank, a discharge port fixedly connected to the bottom of the mixing tank, and a valve rotatably connected to the inner wall of the discharge port;

[0007] The stirring mechanism includes a motor, an output end of which is fixedly connected to a stirring shaft, a material extraction fan blade is fixedly connected to the surface of the stirring shaft, a rudder-shaped blade is fixedly connected to the bottom of the stirring shaft, a fixing rod is fixedly connected to the inner wall of the stirring tank, a material extraction cylinder is fixedly connected to the end of the fixing rod away from the stirring tank, and a plow-shaped block is fixedly connected to the surface of the rudder-shaped blade.

[0008] As a further improvement to the above solution, the top of the motor is fixedly connected to the inner wall of the mounting bracket, and the surface of the stirring shaft is rotatably connected to the inner wall of the stirring tank.

[0009] As a further improvement to the above scheme, the number of the material extraction fan blades is set to three, which are evenly distributed on the surface of the stirring shaft, and the surface of the material extraction fan blades is rotatably connected to the inner wall of the material extraction cylinder.

[0010] The above technical solution involves setting up a material extraction fan blade and a material extraction cylinder. The motor drives the stirring shaft to rotate, which in turn drives the material extraction fan blade to rotate. This process rolls the plastic granules at the bottom of the mixing tank into the material extraction cylinder, conveys them upwards, and then throws them out. This completes the replacement of the plastic granules in the upper and lower layers of the mixing tank, ensuring that the device mixes the plastic granules evenly.

[0011] As a further improvement to the above scheme, the number of plow-shaped blocks is set to two, and the plow-shaped blocks are set on the surface of the rudder-shaped blades according to the rotation direction of the stirring shaft.

[0012] The above technical solution, by setting up plow-shaped blocks, pushes the plastic particles near the inner wall of the mixing tank towards the center of the device when the rudder-shaped blades rotate, ensuring the mixing effect of the plastic particles and improving the practicality of the device.

[0013] As a further improvement to the above solution, the buffer mechanism includes a support ring, a support leg fixedly connected to the bottom of the support ring, a support seat slidably connected to the surface of the support leg, a buffer spring fixedly connected to the inner wall of the support seat, and a limit rod fixedly connected to the inner wall of the support seat.

[0014] As a further improvement to the above solution, the surface of the support ring is fixedly connected to the surface of the mixing tank, the end of the buffer spring away from the support seat is fixedly connected to the inner wall of the support leg, and the surface of the limiting rod is slidably connected to the inner wall of the support leg.

[0015] By using the above technical solution, and by setting a buffer spring and a limiting rod, when the device is running, the mechanical vibration is transmitted to the support leg. Then the buffer spring absorbs the vibration and drives the support leg to slide on the inner wall of the support seat and the surface of the limiting rod through the double limiting of the support seat and the limiting rod, thereby offsetting the mechanical vibration of the device, slowing down the wear rate of the device structure, extending the service life of the device, and improving the practicality of the device.

[0016] As a further improvement to the above solution, the number of the support leg, support seat, buffer spring and limiting rod are all set to four, and they are evenly distributed at the bottom of the support ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a mixing mechanism, specifically a suction fan and a suction cylinder. A motor drives the mixing shaft to rotate, which in turn drives the suction fan to rotate, drawing plastic granules from the bottom of the mixing drum into the suction cylinder, conveying them upwards, and then throwing them out. This process replaces the plastic granules in the upper and lower layers of the mixing drum, ensuring uniform mixing. Furthermore, a plow-shaped block, when the rudder-shaped blades rotate, pushes the plastic granules near the inner wall of the mixing drum towards the center of the device, ensuring effective mixing and improving the device's practicality.

[0019] This invention incorporates a buffer mechanism, specifically a buffer spring and a limiting rod. When the device is running, mechanical vibrations are transmitted to the support leg. The buffer spring absorbs the vibrations and causes the support leg to slide on the inner wall of the support seat and the surface of the limiting rod, thus offsetting the mechanical vibrations, slowing down the wear and tear on the device structure, extending its service life, and improving its practicality.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of a mixing tank for processing TPE plastic granules includes a mixing tank 1, a feeding port 2 fixedly connected to the top of the mixing tank 1, a sealing cover 3 hinged to the top of the feeding port 2, a mounting bracket 4 hinged to the top of the mixing tank 1, a mixing mechanism 5 provided on the inner wall of the mixing tank 1, a buffer mechanism 6 provided on the surface of the mixing tank 1, a discharge port 7 fixedly connected to the bottom of the mixing tank 1, and a valve 8 rotatably connected to the inner wall of the discharge port 7.

[0030] The stirring mechanism 5 includes a motor 501, a stirring shaft 502 fixedly connected to the output end of the motor 501, a material extraction fan blade 503 fixedly connected to the surface of the stirring shaft 502, a rudder-shaped blade 504 fixedly connected to the bottom of the stirring shaft 502, a fixing rod 505 fixedly connected to the inner wall of the stirring tank 1, a material extraction cylinder 506 fixedly connected to the end of the fixing rod 505 away from the stirring tank 1, and a plow-shaped block 507 fixedly connected to the surface of the rudder-shaped blade 504.

[0031] The top of the motor 501 is fixedly connected to the inner wall of the mounting bracket 4, and the surface of the stirring shaft 502 is rotatably connected to the inner wall of the stirring tank 1.

[0032] There are three suction fan blades 503, which are evenly distributed on the surface of the stirring shaft 502. The surface of the suction fan blades 503 is rotatably connected to the inner wall of the suction cylinder 506. The motor 501 drives the stirring shaft 502 to rotate, which in turn drives the suction fan blades 503 to rotate. The plastic granules at the bottom of the mixing tank 1 are rolled into the suction cylinder 506, conveyed upward and then thrown out, thus completing the replacement of the upper and lower layers of plastic granules inside the mixing tank 1 and ensuring that the device mixes the plastic granules evenly.

[0033] There are two plow-shaped blocks 507. The plow-shaped blocks 507 are set on the surface of the rudder-shaped blade 504 according to the rotation direction of the stirring shaft 502. When the rudder-shaped blade 504 rotates, the plow-shaped blocks 507 push the plastic particles near the inner wall of the mixing tank 1 towards the center of the device to ensure the mixing effect of the plastic particles.

[0034] The buffer mechanism 6 includes a support ring 601, a support leg 602 fixedly connected to the bottom of the support ring 601, a support seat 603 slidably connected to the surface of the support leg 602, a buffer spring 604 fixedly connected to the inner wall of the support seat 603, and a limit rod 605 fixedly connected to the inner wall of the support seat 603.

[0035] The surface of the support ring 601 is fixedly connected to the surface of the mixing tank 1. The end of the buffer spring 604 away from the support base 603 is fixedly connected to the inner wall of the support leg 602. The surface of the limiting rod 605 is slidably connected to the inner wall of the support leg 602. When the device is running, mechanical vibration is transmitted to the support leg 602. Then the buffer spring 604 absorbs the vibration and drives the support leg 602 to slide on the inner wall of the support base 603 and the surface of the limiting rod 605 through the double limiting of the support base 603 and the limiting rod 605, thereby offsetting the mechanical vibration of the device, slowing down the wear rate of the device structure, and extending the service life of the device.

[0036] The number of support legs 602, support base 603, buffer spring 604 and limit rod 605 are all four, and they are evenly distributed at the bottom of support ring 601.

[0037] The implementation principle of a mixing tank for processing TPE plastic granules in this embodiment is as follows: When in use, the sealing cover 3 is opened and the plastic granules are put into the mixing tank 1 through the feeding port 2. Then, the motor 501 is started. The motor 501 drives the mixing shaft 502 to rotate, which drives the suction fan blade 503 to rotate. The plastic granules at the bottom of the mixing tank 1 are rolled into the suction cylinder 506, conveyed upward and then thrown out, completing the replacement of the plastic granules in the upper and lower layers inside the mixing tank 1. At the same time, when the rudder-shaped paddle 504 rotates, the plow-shaped block 507 pushes the plastic granules near the inner wall of the mixing tank 1 towards the center of the device, ensuring the mixing effect of the plastic granules. When the device is running, the mechanical vibration is transmitted to the support leg 602. Then, the buffer spring 604 absorbs the vibration and drives the support leg 602 to be doubly limited by the support seat 603 and the limiting rod 605. It slides on the inner wall of the support seat 603 and the surface of the limiting rod 605 to offset the mechanical vibration of the device, slow down the wear rate of the device structure, and extend the service life of the device. After the mixing is completed, the valve 8 is opened and the mixed plastic granules flow out of the device from the discharge port 7.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
