Description

Technical Field

[0001] The present application relates to the technical field of thermoplastic elastomer material processing, and in particular to a pelletizer auxiliary device. Background Art

[0002] Thermoplastic elastomer (TPE) materials, also known as artificial rubber or synthetic rubber materials, have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, and are also easy to process and have a wide range of processing methods like ordinary plastics. Therefore, they are widely used in industry. In the process of processing thermoplastic elastomer (TPE) materials, they are generally extruded through a pelletizer.

[0003] Regarding the above-mentioned related technologies, since the existing horizontal pelletizer generally needs to cool the cut particles through a cooling pool after cutting the thermoplastic elastomer material, the staff in the prior art often need to manually transport the cut particles to the cooling pool in a centralized manner in order to cool the particles, which increases the workload of the staff and needs to be improved. Summary of the invention

[0004] In order to facilitate the workers to transport the pellets after cutting, the present application provides a pelletizer auxiliary device.

[0005] The present application provides a pelletizer auxiliary device, which adopts the following technical solution: A pelletizer auxiliary device comprises a transport mechanism, wherein the transport mechanism is used to be located between a pelletizer body and a cooling pool, the transport mechanism comprises a transport rail, one end of the transport rail is located directly below the discharge end of the pelletizer body, and the other end of the transport rail is inclined and extends to directly above the cooling pool.

[0006] By adopting the above technical solution, compared with the prior art, the staff needs to manually transport the cut particles to the cooling pool in a centralized manner in order to cool the particles, which increases the workload of the staff. The present application sets a transport rail so that the particles passing through the pelletizer can automatically fall into the cooling pool along the inclined direction of the transport rail, thereby eliminating the need for the staff to manually transport the particles to the cooling pool, effectively facilitating the staff to transport the extruded and cut particles, thereby reducing the workload of relevant personnel and improving the overall cutting efficiency of the material.

[0007] Preferably, the transport mechanism further includes a transport mesh frame and a lifting assembly. The bottom of the transport mesh frame is located in the coolant of the cooling tank. The top of the transport mesh frame is open and is located directly below the transport guide rail. The lifting assembly is used to lift the transport mesh frame, so that the transport mesh frame is separated from the liquid level in the cooling tank.

[0008] By adopting the above technical solution, the arrangement of the transport mesh frame and the lifting assembly enables the particles that roll to directly above the cooling tank via the transport guide rail to fall into the transport mesh frame and come into contact with the coolant when reaching the bottom of the transport mesh frame, thereby realizing the cooling of the cut particles. And it enables the staff to lift the transport mesh frame by controlling the lifting assembly, so that the cooled particles are separated from the coolant, which is convenient for subsequent drying or baking of the particles, effectively replacing the manual extraction operation of the staff, improving the extraction efficiency and facilitating the operation of the staff.

[0009] Preferably, the transport mesh frame includes a frame body and a mesh body. The lifting assembly is used to lift the frame body. The end of the mesh body is rotatably connected to the frame body. A rotating mechanism is also arranged on the frame body, and the rotating mechanism is used to drive the mesh body to rotate.

[0010] By adopting the above technical solution, the specific arrangement of the transport mesh frame enables the rotating mechanism to drive the mesh body to rotate after the lifting assembly lifts the frame body, so that the mesh body is tilted, and thus the particles in the mesh body can roll to one end of the mesh body along the tilted direction of the mesh body, which is convenient for discharging the particles in the mesh body, thereby replacing the manual extraction by relevant personnel and improving the discharging efficiency of the particles.

[0011] Preferably, the rotating mechanism includes a sliding frame, a driving frame and a linkage assembly. The sliding frame is slidably connected to the mesh body, and the sliding direction is perpendicular to the rotation axis direction of the mesh body itself. The driving frame is rotatably connected to the sliding frame. The driving frame is slidably connected to the mesh body, and the sliding direction is perpendicular to the rotation axis direction of the mesh body itself. The linkage assembly is used to drive the driving frame to slide.

[0012] By adopting the above technical solution, the arrangement of the rotating mechanism enables the linkage assembly to drive the driving frame to slide, so that the driving frame drives the sliding frame to slide together, and then the sliding frame drives the end of the mesh body away from its rotatable connection to move upward, thereby realizing the driving of the rotation of the mesh body, effectively facilitating the control by relevant personnel.

[0013] Preferably, the linkage assembly includes a linkage gear and two linkage racks. The linkage gear is rotatably connected to the frame body. One of the linkage racks is connected to the cooling pool, and the other linkage rack is slidably connected to the frame body and is used to drive the driving frame to slide. The two linkage racks are respectively located on opposite sides of the linkage gear and are both meshed with the linkage gear.

[0014] By adopting the above technical solution, the setting of the linkage assembly enables the linkage gear to displace relative to the linkage rack on the cooling pool while being meshed during the sliding process of the frame relative to the cooling pool, so that the linkage gear rotates, and further enables the linkage gear to drive the other linkage rack to displace, thereby effectively realizing the linkage between the driving frame and the frame, saving the active device for driving the driving frame to slide, and facilitating the operation of relevant personnel.

[0015] Preferably, the sliding direction of the linkage rack slidably connected to the frame body is the same as the sliding direction of the driving frame, and the driving frame is located on the displacement path of the linkage rack slidably connected to the frame body. An insertion slot for inserting the linkage rack is further provided at the bottom of the driving frame.

[0016] By adopting the above technical solution, the setting of the insertion slot enables the linkage rack to drive the driving frame to slide smoothly by inserting into the insertion slot at the bottom of the driving frame during the sliding process of the linkage rack on the frame, effectively ensuring the stability of the driving frame during sliding.

[0017] Preferably, the number of the linkage assemblies is set to several, and the several linkage assemblies are respectively located on opposite sides of the frame body.

[0018] By adopting the above technical solution, the setting of several linkage assemblies enables several linkage assemblies to drive the rotation of the frame body simultaneously, thereby effectively ensuring the stability of the driving of the frame body and ensuring the smooth rotation of the frame body.

[0019] Preferably, an opening is further provided on the side wall of one end of the frame body rotatably connected to the frame. A closing frame is provided on the opening of the frame body. The closing frame is rotatably connected to the frame body and is used to close the opening of the frame body. A linkage member is further provided on the frame body, and the linkage member is used to drive the closing frame to rotate.

[0020] By adopting the above technical solution, the setting of the closing frame and the linkage frame enables the linkage member to drive the closing frame to rotate when the frame body rotates relative to the frame, so as to open the opening at the downwardly inclined end of the frame body, enabling the particles in the frame body to smoothly pass out through the opening, effectively ensuring the smooth passage of the particles, and at the same time reducing the probability of the particles accidentally detaching from the frame body.

[0021] Preferably, the linkage member includes a linkage frame. One end of the linkage frame is rotatably connected to the closing frame, and the other end is rotatably connected to the sliding frame.

[0022] By adopting the above technical solution, the arrangement of the linkage frame enables one end of the linkage frame to be displaced when the frame rotates, and then the other end of the linkage frame drives the closing frame to rotate, realizing the drive of the closing frame, effectively realizing the linkage between the closing frame and the frame, thereby saving the active device for driving the rotation of the closing frame and facilitating the operation of the staff.

[0023] Preferably, an opening is also formed through the inner side wall of the cooling pool close to the closing frame. A discharge guide rail is provided on the side wall of the cooling pool. One end of the discharge guide rail is located directly below the opening of the cooling pool, and a conveyor belt is provided below the discharge guide rail.

[0024] By adopting the above technical solution, the arrangement of the discharge guide rail enables the particles discharged from the frame to fall onto the discharge guide rail through the opening on the cooling pool and fall downward onto the conveyor belt along the inclined direction of the discharge guide rail, transporting the particles to the next process, effectively facilitating the operation of the staff and replacing the manual transportation of the staff.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The arrangement of the transport guide rail enables the particles discharged from the granulator to automatically fall into the cooling pool along the inclined direction of the transport guide rail, so that there is no need for the staff to manually transport the particles into the cooling pool, effectively facilitating the staff to transport the particles after extrusion and cutting, reducing the workload of relevant personnel, and improving the cutting efficiency of the material as a whole. 2. The arrangement of the transport mesh frame and the lifting assembly enables the particles that roll to directly above the cooling pool via the transport guide rail to fall into the transport mesh frame and come into contact with the cooling liquid when reaching the bottom of the transport mesh frame, thereby realizing the cooling of the cut particles, and enabling the staff to lift the transport mesh frame by controlling the lifting assembly, so that the cooled particles are separated from the coolant, facilitating the subsequent drying or baking of the particles, effectively replacing the manual removal operation of the staff, improving the removal efficiency and facilitating the operation of the staff; 3. The specific arrangement of the transport mesh frame enables the rotation mechanism to drive the frame to rotate after the lifting assembly lifts the frame body, causing the frame to tilt, so that the particles in the frame can roll to one end of the frame along the inclined direction of the frame, facilitating the discharge of the particles in the frame, thereby replacing the manual removal by relevant personnel and improving the discharge efficiency of the particles.

Detailed implementation manners

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0033] Embodiment 1: Embodiment 1 of the present application discloses a granulator auxiliary device. Referring to Figure 1 , the granulator auxiliary device includes a transportation mechanism 1, and the transportation mechanism 1 is used to be located between the granulator main body 2 and the cooling pool 3. The transportation mechanism 1 includes a transportation guide rail 11, one end of the transportation guide rail 11 is located directly below the discharge end of the granulator main body 2, and the other end of the transportation guide rail 11 is inclined and extends above the cooling pool 3.

[0034] Referring to Figure 1 , in the embodiment of the present application, the above-mentioned granulator main body 2 is set as a horizontal granulator, which is placed on the ground and internally provided with an extrusion device and a cutting device to extrude and cut materials. The cutting device can be a combined mechanism of a cutting knife and a cylinder, and the cylinder is installed on the top of the granulator main body 2. The piston rod of the cylinder is vertically downward and fixedly connected to the top of the cutting knife to drive the cutting knife to slide downward, so as to cut the extruded materials. The cutting device in the granulator main body 2 is prior art, so it will not be elaborated too much here.

[0035] Reference Figure 1 In the embodiment of the present application, a control device is also provided in the pelletizer body 2, which can detect the discharge speed of the particles and control the extrusion speed of the material by the extrusion device according to the discharge speed, thereby achieving the regulation of the discharge speed and ensuring the pelletizing effect of the pelletizer body 2.

[0036] Reference Figure 1 One end of the transport guide rail 11 is fixedly connected to the discharge end of the pelletizer body 2, and the other end is extended obliquely downward in the direction away from the pelletizer body 2, and extends to just above the top opening of the cooling pool 3. In the embodiment of the present application, a coolant is provided in the cooling pool 3, and a cooling device is provided in the cooling pool 3 for cooling the coolant. The cooling pool 3 is a prior art, so it is not described here.

[0037] The implementation principle of a pelletizer auxiliary device in Example 1 of the present application is as follows: the particles passing through the pelletizer body 2 can automatically fall into the cooling pool 3 along the inclined direction of the transport guide rail 11, thereby eliminating the need for staff to manually transport the particles to the cooling pool 3, effectively facilitating the staff to transport the particles after extrusion and cutting, thereby reducing the workload of relevant personnel and improving the overall pelletizing efficiency of the material.

[0038] Embodiment 2: The difference between the second embodiment of the present application and the first embodiment is that: Figure 2 and Figure 3 The top of the side wall of the cooling pool 3 away from the pelletizer body 2 is also provided with an opening. The transport mechanism 1 further comprises a transport net frame 12 and a lifting assembly 13. In the embodiment of the present application, the lifting assembly 13 is configured as a plurality of cylinders, each of which is fixedly mounted on the outer wall of the cooling pool 3 by bolts, and the piston rods are all arranged vertically upward (i.e., arranged upward along the height direction of the cooling pool 3).

[0039] Reference Figure 2 and Figure 3 The transport net frame 12 includes a frame 121 and a frame 122. The frame 121 is located directly below the corresponding end of the transport guide rail 11. The top of the frame 121 is close to one side of the pelletizer body 2 along its length direction, and both sides along its width direction are extended outward, so that the frame 121 can be placed on the cooling pool 3 by abutment, and the top of the frame 121 is located in the chamber of the cooling pool 3. The top piston rod of the above-mentioned cylinder in the lifting assembly 13 is fixedly connected to the top and bottom walls of the frame 121.

[0040] Reference Figure 2 and Figure 3, the bottom end of the frame 122 on the side away from the granulator body 2 is rotatably connected to the end of the frame body 121 through a pin shaft, and the bottom of the frame 122 is abutted against the top of the frame body 121, so that the frame body 121 supports the frame 122. A rotating mechanism 4 is also provided on the frame body 121. In the embodiment of the present application, the number of the rotating mechanisms 4 is set to two, and they are respectively located at both ends of the frame body 121 along its width direction to ensure the stability of the rotational drive of the frame 122.

[0041] Refer to Figure 3 , each rotating mechanism 4 includes a sliding frame 41, a driving frame 42 and a linkage assembly 43, and each linkage assembly 43 includes a linkage gear 431 and two linkage racks 432. The two linkage racks 432 in each linkage assembly 43 are respectively located on opposite sides of the corresponding linkage gear 431, are arranged in parallel, and are both engaged with the corresponding linkage gear 431.

[0042] Refer to Figure 2 and Figure 3 , one of the linkage racks 432 in each linkage assembly 43 is fixedly installed on the inner side wall of the cooling pool 3, the linkage gears 431 in each linkage assembly 43 are arranged on the corresponding side walls of the frame body 121, and are all rotatably connected to the frame body 121 through a pin shaft. The other linkage rack 432 in each linkage assembly 43 is slidably connected to the side wall of the frame body 121 through a slide rail, and the sliding direction is the same as the sliding direction of the frame body 121. An insertion portion 5 extends upward from the top of the linkage rack 432, and the insertion portion 5 is integrally formed with the corresponding linkage rack 432.

[0043] Refer to Figure 3 and Figure 4 , each sliding frame 41 is located inside the frame body 121, and the two sliding frames 41 are respectively located on opposite sides of the frame 122 along its width direction. Each sliding frame 41 is slidably connected to the bottom of the frame 122 through a slide rail, and the sliding direction is the length direction of the frame 122. Each driving frame 42 is located on the side of the corresponding sliding frame 41 away from the frame 122, and is rotatably connected to the corresponding sliding frame 41 through a pin shaft, and the extending direction of the rotation axis is the width direction of the frame 122.

[0044] Refer to Figure 4 and Figure 5, each driving frame 42 is slidably connected to the inner side wall of the frame body 121 through a slide rail, and the sliding direction is the sliding direction of the frame body 121 itself, so that the sliding direction of the driving frame 42 is the same as that of the corresponding linkage rack 432. An insertion groove 6 for inserting the top insertion part 5 of the corresponding linkage rack 432 is formed at the bottom of each driving frame 42, so that the insertion part 5 can be inserted into the insertion groove 6 at the bottom of the corresponding driving frame 42, thereby ensuring the stability of the linkage rack 432 driving the driving frame 42 to slide.

[0045] Referring to Figure 2 , Figure 3 and Figure 4 , in the initial state, that is, when the frame body 121 does not move upward under the drive of the lifting assembly 13, at this time the driving frame 42 is located at the bottom of its own sliding path, and at this time the driving frame 42 does not abut against the corresponding linkage rack 432. When the lifting assembly 13 drives the frame body 121 to move upward, the frame body 121 slides relative to the cooling pool 3, and then the linkage gear 431 slides relative to the linkage rack 432 fixed in the cooling pool 3, and then the linkage gear 431 rotates.

[0046] Referring to Figure 2 , Figure 4 and Figure 5 , when the linkage gear 431 rotates, the linkage gear 431 drives the linkage rack 432 arranged on the frame body 121 to move, and makes the linkage rack 432 slide upward relative to the frame body 121, so as to gradually approach the corresponding driving frame 42. When the bottom of the frame 122 reaches the opening height at the end of the cooling pool 3, the insertion frame at the top of the linkage gear 431 on the frame body 121 is inserted into the insertion groove 5 at the bottom of the corresponding driving frame 42, and after abutting against the inner top wall of the insertion groove 5, it drives the driving frame 42 to slide upward.

[0047] Referring to Figure 3 and Figure 4 , during this process, the driving frame 42 drives the corresponding sliding frame 41 to slide upward together, and then the sliding frame 41 drives the end of the frame 122 away from its hinge end to move upward, and then the frame 122 rotates. During this process, the sliding frame 41 slides relative to the frame 122, and the sliding frame 41 rotates relative to the corresponding driving frame 42 to adapt to the rotation of the frame 122.

[0048] Referring to Figure 2 , Figure 4 and Figure 5, an opening is also provided on the side wall at one end of the frame body 122 away from the pelletizer body 2. A closing frame 123 is arranged in the opening of the frame body 122. The top of the closing frame 123 is rotatably connected to the frame body 122 through a pin shaft. When the closing frame 123 abuts against the frame body 122, the opening on the frame body 122 is closed. A linkage member 7 is also arranged on the frame body 122. In the embodiment of the present application, the number of the linkage members 7 is set to two and are respectively located on both sides of the frame body 122 along its width direction.

[0049] Referring to Figure 4 and Figure 5 , one end of each sliding frame 41 extends into the opening of the frame body 122, and a through groove for the extended part of the sliding frame 41 to slide is provided on the frame body 122. The width of the through groove is smaller than the length and width of the cut particles.

[0050] Referring to Figure 4 and Figure 5 , each linkage member 7 includes a linkage frame 71. The top end of each linkage frame 71 is rotatably connected to the middle part of the closing frame 123 along its height direction through a pin shaft. The other end of each linkage member 7 is rotatably connected to the part of the corresponding sliding frame 41 extending into the frame body 122 through a pin shaft.

[0051] Referring to Figure 2 , Figure 4 and Figure 5 , in the initial state, that is, when the frame body 122 does not rotate, the closing frame 123 abuts against the frame body 122 to close the opening on the frame body 122. When the sliding frame 41 slides relative to the frame body 122, that is, when the bottom height of the frame body 122 is greater than the opening on the cooling pool 3, the sliding frame 41 drives one end of the corresponding linkage frame 71 to displace, and further makes the other end of the linkage frame 71 drive the closing frame 123 to rotate, and makes the bottom of the closing frame 123 rotate into the frame body 122, so as to open the opening on the frame body 122, enabling the particles in the frame body 122 to roll along the inclined direction of the frame body 122 and pass out of the opening of the opened frame body 122 to the outside of the cooling pool 3.

[0052] Referring to Figure 2 , a discharge guide rail 8 is further arranged at one end of the cooling pool 3 away from the cutting machine body 2. One end of the discharge guide rail 8 is located directly below the opening on the cooling pool 3 and is fixedly connected to the outer side wall of the cooling pool 3. The other end of the discharge guide rail 8 extends obliquely downward. A conveyor belt 9 is further arranged directly below the other end of the discharge guide rail 8 away from the cooling pool 3 for transporting the passed-out particles, so that the particles enter the next process step.

[0053] The implementation principle of the auxiliary device of the granulator in Embodiment 2 of the present application is as follows: When the lifting assembly 13 drives the frame 121 to move upward, the frame 121 slides relative to the cooling pool 3, so that the linkage gear 431 moves relative to the linkage rack 432 fixed in the cooling pool 3, and then the linkage gear 431 rotates. At this time, the linkage gear 431 drives another linkage rack 432 to slide upward relative to the frame 121, so as to gradually approach the corresponding driving frame 42.

[0054] When the bottom of the frame 122 reaches the opening height at the end of the cooling pool 3, the insertion frame at the top of the linkage gear 431 on the frame 121 is inserted into the insertion slot 5 at the bottom of the corresponding driving frame 42 and drives the driving frame 42 to slide upward. During this process, the driving frame 42 drives the frame 122 to rotate through the sliding frame 41.

[0055] During this process, the sliding frame 41 slides relative to the frame 122, and the sliding frame 41 rotates relative to the corresponding driving frame 42 to adapt to the rotation of the frame 122. At this time, the sliding frame 41 drives one end of the corresponding linkage frame 71 to move, so that the other end of the linkage frame 71 drives the closing frame 123 to rotate, thereby realizing the opening of the opening on the frame 122.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
