Description

Technical Field

[0001] This utility model relates to thermoplastic elastomers, and in particular to a pretreatment device for thermoplastic elastomers before drying. Background Technology

[0002] Thermoplastic elastomers are a class of polymeric materials that combine the elasticity of rubber with the processing characteristics of thermoplastic plastics. At room temperature, they exhibit physical and mechanical properties similar to vulcanized rubber (such as high elasticity and flexibility), while at high temperatures they can be repeatedly molded and processed like plastics through melting and plasticization.

[0003] During the production process, thermoplastic elastomers need to be cleaned to remove dust. After cleaning, they need to be dried. However, moisture will remain on the surface of the cleaned thermoplastic elastomers. If the excess moisture is not removed, the energy consumption of the drying equipment will increase during the drying process, thereby increasing production costs.

[0004] In response, we propose a pretreatment device for thermoplastic elastomers before drying. Utility Model Content

[0005] This invention proposes a pretreatment device for thermoplastic elastomers before drying, which solves the above-mentioned problems existing in the use of existing technologies.

[0006] The technical solution of this utility model is as follows: a pretreatment device for thermoplastic elastomer before drying includes a treatment cylinder, a treatment chamber is opened inside the treatment cylinder, a feed pipe is fixed inside the upper side wall of the treatment chamber, a vibrating plate that can move up and down is installed inside the treatment chamber, and a number of water leakage holes that penetrate from top to bottom are opened inside the vibrating plate.

[0007] A discharge port is provided in the curved sidewall at the rear of the processing chamber, and a movable door is installed on the processing cylinder to block the discharge port. A discharge mechanism is installed inside the processing chamber.

[0008] A drain pipe is connected to the bottom wall of the processing chamber.

[0009] A further feature of this invention is that: a limiting rod capable of sliding up and down is symmetrically installed on the lower side of the vibrating plate, and a striking plate is fixedly provided on the lower side of the two limiting rods together;

[0010] An electromagnet ring is installed on the lower side of the vibrating plate, and a permanent magnet ring is installed on the upper side of the impact plate. The permanent magnet ring is attracted to the lower side of the electromagnet ring by magnetic force.

[0011] A further feature of this invention is that a plurality of inserts capable of being inserted into the drainage holes are fixed on the upper side of the impact plate.

[0012] A further feature of this invention is that three rotating shafts are rotatably connected to the rear side wall of the lower side of the processing cavity, and a rotating wheel is fixedly connected to each of the rotating shafts. A drive rod is eccentrically hinged to the front side of each of the rotating wheels, and the upper side of each drive rod is hinged to the lower side of the impact plate.

[0013] The processing cylinder is equipped with a power source assembly for driving the rotating shaft.

[0014] A further feature of this invention is that the power source assembly includes a primary motor for driving one of the rotating shafts to rotate, and the primary motor is mounted on the front side wall of the processing cylinder.

[0015] Each of the rotating shafts is fixed with a synchronous pulley, and all the synchronous pulleys are connected by a synchronous belt.

[0016] A further feature of this invention is that a plurality of tensioning rollers are symmetrically rotatably connected inside the processing cavity, and the curved sidewalls of each tensioning roller are pressed against the synchronous belt.

[0017] A further feature of this invention is that: a mounting box is fixedly provided on the upper side of the processing cylinder, a mounting frame is fixedly provided inside the mounting box, and a No. 3 motor is mounted on the mounting frame;

[0018] The piston rod of the No. 3 motor is fixedly provided with a swing rod connected to the limiting rod at its end, and the curved side wall of the mounting box is provided with a swing groove for the swing rod to swing.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] After the thermoplastic elastomer falls onto the vibrating plate in the processing chamber, the up-and-down vibration of the vibrating plate removes the moisture from the surface of the thermoplastic elastomer, so as to effectively reduce the energy consumption of the drying equipment and improve economic efficiency in the subsequent drying process.

[0021] During vibration, the vibrating plate and the impact plate are separated, and the insert is not inserted into the drain hole. This allows the water on the surface of the thermoplastic elastomer to be shaken off and fall into the bottom of the processing chamber through the drain hole. After the water removal process is completed, the insert is inserted into the drain hole under the magnetic force of the electromagnet ring and the permanent magnet ring, thereby pushing out the thermoplastic elastomer stuck in the drain hole, preventing a reduction in its output and affecting the amount of water leakage from the drain hole.

Detailed Implementation

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 3As shown, a pretreatment device for thermoplastic elastomers before drying includes a treatment cylinder 11, a treatment chamber 12 inside the treatment cylinder 11, a feed pipe 13 fixedly installed inside the upper side wall of the treatment chamber 12, through which the thermoplastic elastomer (hereinafter referred to as "the product") enters the treatment chamber 12. A drain pipe 38 is fixedly installed inside the bottom wall of the treatment chamber 12, and moisture from the surface of the product drips to the bottom of the treatment chamber 12 and is discharged through the drain pipe 38. Three rotating shafts 20 are rotatably connected to the rear side wall of the side. A power source assembly for driving each of the rotating shafts 20 is installed on the processing cylinder 11 so that the three rotating shafts 20 can rotate synchronously. A rotating wheel 21 is fixedly connected to each of the rotating shafts 20. A drive rod 22 is eccentrically hinged to the front side of each of the rotating wheels 21. A collision plate 16 that can move up and down is installed in the processing cavity 12. The upper side of each drive rod 22 is hinged to the lower side of the collision plate 16.

[0030] Furthermore, a vibrating plate 14 capable of moving up and down is installed inside the processing chamber 12. Several vertically penetrating drainage holes 15 are opened inside the vibrating plate 14. Several inserts 19 capable of being inserted into the drainage holes 15 are fixed on the upper side of the impact plate 16. Furthermore, limiting rods 36 are symmetrically fixed on the upper side of the impact plate 16. Both limiting rods 36 are slidably connected to the lower side of the vibrating plate 14. An electromagnet ring 17 is installed on the lower side of the vibrating plate 14, and a permanent magnet ring 18 is installed on the upper side of the impact plate 16.

[0031] The cleaned product enters the processing chamber 12 through the feed pipe 13 and falls onto the vibrating plate 14. Subsequently, the three rotating shafts 20 rotate synchronously under the drive of the power source assembly, thereby driving the three rotating wheels 21 to rotate synchronously, so that the rotating wheels 21 can drive the drive rods 22 to swing eccentrically, thereby enabling the three drive rods 22 to drive the vibrating plate 14 and the impact plate 16 to vibrate up and down.

[0032] During vibration, the opposing magnetic poles of the electromagnet ring 17 and the permanent magnet ring 18 are the same. Based on the principle of like poles repelling each other, the vibrating plate 14 and the impact plate 16 are separated, and the insert 19 is not inserted into the drain hole 15. This allows water thrown off the product during vibration to fall through the drain hole 15 to the bottom of the processing chamber 12 and be discharged through the drain pipe 38. Furthermore, to prevent water from accumulating at the bottom of the processing chamber 12, the bottom wall of the processing chamber 12 is sloped, and the drain pipe 38 is located at the lowest point of the bottom wall of the processing chamber 12, so that water falling at the bottom of the processing chamber 12 can flow into the drain pipe 38 and be discharged.

[0033] The specific structure of the power source assembly is as follows: the power source assembly includes a primary motor 23 for driving one of the rotating shafts 20 to rotate. The primary motor 23 is mounted on the front side wall of the processing cylinder 11, and each of the rotating shafts 20 is fixed with a synchronous pulley 24. The synchronous pulleys 24 are connected to each other by a synchronous belt 25. When the primary motor 23 drives one of the rotating shafts 20 to rotate, the synchronous pulleys 24 on the rotating shaft 20 drive the other two synchronous pulleys 24 to rotate through the synchronous belt 25, so that the three rotating shafts 20 can rotate synchronously.

[0034] Furthermore, several tension rollers 26 are symmetrically rotatably connected inside the processing cavity 12. The curved sidewalls of each tension roller 26 press against the synchronous belt 25 to ensure that the synchronous belt 25 can maintain a taut state and prevent the three rotating shafts 20 from failing to rotate synchronously.

[0035] In addition, a mounting box 31 is fixedly provided on the upper side of the processing cylinder 11, and a mounting frame 32 is fixedly provided inside the mounting box 31. A No. 3 motor 33 is mounted on the mounting frame 32. A swing rod 34 is fixedly provided at the end of the piston rod of the No. 3 motor 33. A swing groove 35 is provided in the curved side wall of the mounting box 31 for the swing rod 34 to swing. A movable door 39 is fixedly provided on the side of the swing rod 34 away from the No. 3 motor 33, which blocks the discharge port 37.

[0036] After the product has been spun dry, the electromagnet ring 17 changes its magnetic poles so that the magnetic poles of the electromagnet ring 17 and the permanent magnet ring 18 are opposite. Through the principle of attraction between opposite magnetic poles, the permanent magnet ring 18 is brought close to and attracted to the lower side of the electromagnet ring 17, thereby driving the impact plate 16 to move upward and causing the insertion post 19 to be inserted into the corresponding drain hole 15, thereby pushing out the product stuck in the drain hole 15 and preventing the product from remaining in the vibrating plate 14.

[0037] Subsequently, the No. 3 motor 33 drives the swing rod 34 to rotate, thereby causing the movable door 39 to rotate and no longer block the discharge port 37, so that technicians can take out the product from the processing chamber 12.

[0038] After the product in the processing chamber 12 has been discharged, the impact plate 16 separates from the vibrating plate 14, the insertion post 19 is no longer inserted into the drain hole 15, and the movable door 39 is once again covered on the outside of the discharge port 37 to facilitate the next operation.

[0039] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
