Description

Technical Field

[0001] This invention relates to the field of rubber roller technology, and in particular to a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and a method for disassembling and assembling it. Background Technology

[0002] Currently, pelletizers are widely used to cut various thermoplastics, capable of cutting sheets of a certain width and thickness into pellets. The rubber roller is one of the core components of the pelletizer; its function is to cut the material into pellets of the required size by rotating and contacting the blades. Chinese patent application number CN202021517971.0 proposes a rubber roller for a pelletizer that does not experience jamming or delamination. However, it still has the following drawbacks during use:

[0003] 1. Inconvenient to disassemble and assemble: Because the pelletizer operates at high speed for a long time, the rubber rollers often wear out, become damaged, or require maintenance. Traditional pelletizers require disassembling the entire pelletizing structure to replace or repair the rubber rollers, resulting in excessive downtime and affecting production efficiency.

[0004] 2. The length is not easy to adjust. The length of traditional rubber rollers is usually fixed, which makes it impossible to assemble with different models of pelletizing equipment. It is easy to have incompatible situations such as the rubber roller being too long or too short, which has certain limitations.

[0005] 3. Inability to cool and clean in a timely manner: Under prolonged high-intensity operation, the various parts of the pelletizer are prone to heat generation due to friction, and the rubber rollers are the place with relatively large heat generation. Traditional pelletizers lack a mechanism for cooling and cleaning the rubber rollers, which affects their service life. Summary of the Invention

[0006] The purpose of this invention is to provide a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and a method for doing so. The disassembly and assembly components allow for the assembly of two adjacent rubber rollers to adjust their length, improving the adaptability of the rollers to different pelletizer equipment. The detachable connection between the rubber rollers, connecting sleeves, and mounting shaft facilitates disassembly and assembly, improving the convenience of roller replacement. Through the combined action of the water inlet, first water guide, second water guide, and third water guide, cold water can be introduced into the cooling chamber inside the roller body to cool the heated rollers. The cooling water, after absorbing heat, can be discharged through a nozzle to clean the roller surface, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high-quality pelletizer rubber roller that can be quickly disassembled and assembled includes a rubber roller, a disassembly and assembly assembly, a cooling assembly, and an mounting shaft. The rubber roller is composed of a roller body and a roller ring. The roller body and the roller ring are slidably connected. Both ends of the roller surface of the roller body are provided with sliding grooves. The roller ring is welded with a slider that matches the sliding groove. The roller body is provided with a cooling chamber. A first shaft hole is opened at the center of the roller body.

[0009] The disassembly and assembly assembly includes a connecting sleeve, through which the rubber roller is disassembled and connected. The connecting sleeve has a water storage chamber inside, and a second shaft hole is opened at the center of the connecting sleeve.

[0010] The cooling assembly includes a fixed sleeve, which is hollow inside and filled with cooling water. A bushing is fixedly connected to the inner end of the fixed sleeve, and a water inlet is movably connected to the outer end of the fixed sleeve through a bearing. The water inlet is in liquid communication with the inside of the fixed sleeve.

[0011] The mounting shaft is compatible with both the first shaft hole and the second shaft hole. The mounting shaft has keyways symmetrically arranged about the center. Fixed shafts are welded to both ends of the mounting shaft. The fixed shafts are connected to the bushings by bolts.

[0012] Furthermore, both ends of the roller body are provided with a first water guide in a circular array, the first water guide is in communication with the inside of the cooling chamber, and the end of the first water guide is fixedly connected to a first flange. Both ends of the connecting sleeve are provided with a second water guide in a circular array, the second water guide is in communication with the inside of the water storage chamber, and the end of the second water guide is fixedly connected to a second flange. The positions of the first water guide and the second water guide correspond to each other, and the first flange and the second flange are connected by bolts.

[0013] Furthermore, the inner ring of the roller ring is provided with an annular array of insertion holes, and both ends of the connecting sleeve are provided with an annular array of first guide rods adapted to the insertion holes. The first guide rods and the insertion holes are slidably connected, and the ends of the first guide rods are threaded with nuts.

[0014] Furthermore, the inner end of the fixed sleeve is provided with a second guide rod and a third water inlet in an annular array. The second guide rod is slidably connected to the insertion hole. The third water inlet is kept in liquid communication with the inside of the fixed sleeve. The end of the third water inlet is fixedly connected to a fourth flange. The fourth flange is connected to the first flange by bolts.

[0015] Furthermore, a first water guide pipe is fixed to the outer end of the water inlet. The first water guide pipe is in liquid communication with the inside of the water inlet. A nozzle and a shut-off valve are installed on the first water guide pipe, and the nozzle nozzle faces the surface of the rubber roller.

[0016] Furthermore, the first water guide pipe is sealed to a second water guide pipe via a third flange, and a nozzle is installed on the second water guide pipe.

[0017] Furthermore, a threaded hole is provided inside the mounting shaft, and a bolt is threaded into the threaded hole. A fixing plate is welded onto the connecting sleeve, and the fixing plate is connected to the mounting shaft by bolts.

[0018] This invention provides a technical solution: a method for quickly disassembling and assembling a high-quality pelletizer rubber roller, comprising the following steps:

[0019] Step 1: Fix the connecting sleeve onto the mounting shaft: First, put the connecting sleeve onto the mounting shaft, then find the position of the threaded hole, and fix the fixing plate to the threaded hole with bolts to realize the installation of the connecting sleeve on the mounting shaft;

[0020] Step 2: Fix the roller body to both sides of the connecting sleeve: First, put the rubber roller on the mounting shaft, then move the roller body until the first water guide port and the second water guide port are tightly attached. Fix the first flange and the second flange together with bolts to achieve a sealed connection between the first water guide port and the second water guide port.

[0021] Step 3: Fix the roller ring to the roller body: First, pull the roller ring in the groove. At this time, the first guide rod is inserted into the insertion hole until the roller ring and the connecting sleeve are tightly attached. Connect the nut to the first guide rod to limit the movement of the roller ring, so that the roller ring can protect the first and second water inlets.

[0022] Step 4: Fix the fixing sleeve to both ends of the mounting shaft: First, put the sleeve on the fixing shaft so that the third water guide is aligned with the first water guide. Then, fix the fourth flange to the first flange with bolts to achieve a sealed connection between the third water guide and the first water guide. Finally, fix the sleeve to the fixing shaft with bolts.

[0023] Step 5: Seal the connection between the second water guide pipe and the first water guide pipe: Select a certain number of second water guide pipes according to the length of the assembled rubber roller. After fixing multiple second water guide pipes together with the third flange, fix them to the first water guide pipe with the third flange to achieve a sealed connection between the first water guide pipe and the second water guide pipe.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention proposes a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and its disassembly and assembly method. Two rubber rollers can be assembled and spliced ​​through the disassembly and assembly components to achieve the adjustment of the length of the rubber roller, thereby improving the compatibility between the rubber roller and different models of pelletizer equipment. The connecting sleeve is put on the mounting shaft and fixed with bolts. Then, the two roller bodies are put on the mounting shaft at the left and right ends of the connecting sleeve. The first water guide port and the second water guide port are aligned and pressed tightly together. The first water guide port and the second water guide port are sealed and connected by the first flange and the second flange. Then, the first guide rod is aligned with the insertion hole and the roller ring is moved until the end face of the roller ring is pressed tightly against the end face of the connecting sleeve. The roller ring is limited by the nut, which can protect the first water guide port and the second water guide port and facilitate the assembly of rubber rollers of different lengths according to the requirements.

[0026] 2. This invention proposes a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and its disassembly and assembly method. Through the detachable connection of the rubber roller, connecting sleeve, fixing sleeve and mounting shaft, the rubber roller can be easily disassembled (at this time, there is no cooling water inside the rubber roller, and the cooling water inside the rubber roller can be pumped out from the water inlet end beforehand). When the rubber roller is worn due to the long service time of the pelletizer, the nuts near the roller rings at both ends can be removed first, and the roller rings at both ends can be moved to expose the third water guide port and the first water guide port at both ends. The bolts on the fourth flange and the first flange, as well as the bolts on the bushing and the fixing shaft, can be removed so that the fixing sleeve can be removed from the mounting shaft. The worn rubber roller can be located, and the connecting sleeve connected to it can be removed. Then the worn rubber roller can be removed from the mounting shaft for replacement. Finally, the newly installed rubber roller can be reinstalled.

[0027] 3. The present invention proposes a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and the disassembly and assembly method thereof. The cooling component can cool down the rubber roller that has been used for a long time, which can extend the service life of the rubber roller. Sufficient cooling water is introduced into the fixed sleeve from the water inlet end by an external water pump. At this time, the cooling water enters the cooling chamber of the rubber roller at both ends through the third water guide port and the first water guide port, then flows into the water storage chamber in the connecting sleeve through the first water guide port and the second water guide port, and then enters the cooling chamber of the middle rubber roller through the second water guide port and the first water guide port, until the cooling chamber of all rubber rollers is filled with cooling water. The rubber roller can be cooled down while the rubber roller is rotating at high speed.

[0028] 4. The present invention proposes a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, and its disassembly and assembly method. When the cooling water absorbs a certain amount of heat, it needs to be replaced. At this time, the shut-off valve is opened, and new cooling water is introduced from the water inlet. The cooling water enters the fixed sleeve, and then gradually flows to the rubber roller and the connecting sleeve, pushing the original cooling water into the first water guide pipe and the second water guide pipe, and finally spraying it out from the nozzle. At this time, the rubber roller is still rotating, while the water inlet can be kept stationary by the bearing, driving the nozzle to remain stationary, and cleaning the surface of the rubber roller.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To address the technical challenge of achieving rapid assembly and disassembly of rubber rollers, please refer to [link / reference]. Figure 1 and Figures 3-7 This embodiment provides the following technical solution:

[0039] A high-quality pelletizer rubber roller that can be quickly disassembled and assembled includes a rubber roller 1, a disassembly and assembly assembly 2, a cooling assembly 3, and an mounting shaft 4. The rubber roller 1 is composed of a roller body 11 and a roller ring 12. The roller body 11 and the roller ring 12 are slidably connected. Both ends of the roller surface of the roller body 11 are provided with sliding grooves 111. The roller ring 12 is welded with a slider 122 that matches the sliding grooves 111. The roller body 11 is provided with a cooling chamber 112. A first shaft hole 113 is opened at the center of the roller body 11.

[0040] The disassembly and assembly assembly 2 includes a connecting sleeve 21. The rubber roller 1 is disassembled and connected through the connecting sleeve 21. The connecting sleeve 21 is provided with a water storage chamber 25, and a second shaft hole 26 is opened at the center of the connecting sleeve 21.

[0041] The mounting shaft 4 is compatible with both the first shaft hole 113 and the second shaft hole 26. The mounting shaft 4 has keyways 41 symmetrically opened about the center. Both ends of the mounting shaft 4 are welded with fixing shafts 42, and the fixing shafts 42 are connected to the bushings 36 by bolts.

[0042] Both ends of the roller body 11 are provided with a first water guide port 114 arranged in a ring. The first water guide port 114 is kept in liquid communication with the interior of the cooling chamber 112. The end of the first water guide port 114 is fixedly connected to a first flange 115. Both ends of the connecting sleeve 21 are provided with a second water guide port 23 arranged in a ring. The second water guide port 23 is kept in liquid communication with the interior of the water storage chamber 25. The end of the second water guide port 23 is fixedly connected to a second flange 24. The positions of the first water guide port 114 and the second water guide port 23 correspond to each other. The first flange 115 and the second flange 24 are connected by bolts.

[0043] The inner ring 12 has a ring array of insertion holes 121. Both ends of the connecting sleeve 21 are provided with a ring array of first guide rods 22 that are adapted to the insertion holes 121. The first guide rods 22 and the insertion holes 121 are slidably connected. The end of the first guide rods 22 is threaded with a nut.

[0044] The mounting shaft 4 has a threaded hole 43, and a bolt is threaded into the threaded hole 43. A fixing plate 27 is welded onto the connecting sleeve 21, and the fixing plate 27 is connected to the mounting shaft 4 by bolts.

[0045] The specific steps are as follows: First, fit the connecting sleeve 21 onto the mounting shaft 4 through the second shaft hole 26, locate the threaded hole 43, and then fix the fixing plate 27 to the mounting shaft 4 through bolts and the threaded hole 43 to achieve a detachable connection between the connecting sleeve 21 and the mounting shaft 4. Then, fit the roller body 11 onto the mounting shaft 4 through the first shaft hole 113 at the positions on both sides of the connecting sleeve 21, and push the roller body 11 until the side end of the roller body 11 is in contact with the side end of the connecting sleeve 21. At this time, the first water guide port 114 is aligned with the second water guide port 23. Use bolts to connect the first flange 115 and the second... The flange 24 is fixed, so that the first water guide port 114 and the second water guide port 23 are sealed together. Then, the roller ring 12 is moved until it slides on the surface of the roller body 11 until its side end is in contact with the side end of the connecting sleeve 21. At this time, the first water guide port 114 and the second water guide port 23 are both protected inside the roller ring 12. Then, the first guide rod 22 is inserted into the insertion hole 121, and a nut is threaded onto the end of the first guide rod 22 to limit the movement of the roller ring 12. At this time, the detachable connection between the connecting sleeve 21 and the roller body 11 is realized, which can improve the convenience of disassembling the roller body 11.

[0046] It should be noted that, depending on the actual required length of the rubber roller, a certain number of roller bodies 11 and connecting sleeves 21 can be added for assembly and splicing to adjust the length of the rubber roller and increase the applicability of the rubber roller 1. When the length of the rubber roller becomes longer, a certain number of second water guide pipes 311 can be added to supplement the length of the first water guide pipe 32, so that each rubber roller surface is equipped with a nozzle 33 for easy cleaning later.

[0047] To address the technical challenges of cooling and cleaning rubber rollers, please refer to [link / reference]. Figures 2-3 This embodiment provides the following technical solution:

[0048] The cooling assembly 3 includes a fixed sleeve 31, which is hollow inside and filled with cooling water. A bushing 36 is fixedly connected to the inner end of the fixed sleeve 31, and a water inlet 37 is movably connected to the outer end of the fixed sleeve 31 through a bearing. The water inlet 37 is in liquid communication with the inside of the fixed sleeve 31.

[0049] The inner end of the fixed sleeve 31 is provided with a second guide rod 38 and a third water inlet 39 in an annular array. The second guide rod 38 is slidably connected to the insertion hole 121. The third water inlet 39 is kept in liquid communication with the inside of the fixed sleeve 31. The end of the third water inlet 39 is fixedly connected to a fourth flange 310. The fourth flange 310 is connected to the first flange 115 by bolts.

[0050] A first water guide pipe 32 is fixed to the outer end of the water inlet 37. The first water guide pipe 32 is in liquid communication with the inside of the water inlet 37. A nozzle 33 and a shut-off valve 35 are installed on the first water guide pipe 32. The nozzle of the nozzle 33 is facing the surface of the rubber roller 1.

[0051] The first water pipe 32 is sealed to the second water pipe 311 via the third flange 34, and a nozzle 33 is installed on the second water pipe 311.

[0052] Specifically, when the rubber roller 1 generates heat and needs to be cooled after long-term operation, sufficient cooling water is introduced into the fixed sleeve 31 from the water inlet 37 through an external water pump. At this time, the shut-off valve 35 is closed, and the cooling water enters the cooling chamber 112 inside the two end roller bodies 11 through the third water guide port 39 and the first water guide port 114, then enters the water storage chamber 25 inside the connecting sleeve 21 through the first water guide port 114 and the second water guide port 23, and then enters the cooling chamber 112 inside the middle roller body 11 through the second water guide port 23 and the first water guide port 114, until all the cooling chambers 112 inside the roller bodies 11 are filled with cooling water. When the rubber roller 1 generates high temperature due to long-term rotation, the cooling water can cool it down, improve the service life of the rubber roller, and prevent the rubber roller from deforming due to long-term high temperature, which would affect its performance.

[0053] When the cooling water absorbs heat and becomes hot and needs to be replaced, open one inlet end 37 and two shut-off valves 35 to introduce new cooling water into the fixed sleeve 31 from the inlet end 37. This pushes the original cooling water into the first guide pipe 32 and the second guide pipe 311, and finally sprays it out from the nozzle 33. At this time, the mounting shaft 4 is driven to rotate by external force, while the inlet end 37 remains stationary through the bearing. This keeps the first guide pipe 32, the second guide pipe 311 and the nozzle 33 fixed to it stationary. The surface of the roller is sprayed with water to clean it under the rotation of the rubber roller until all the cooling water in the cooling chamber 112 is replaced.

[0054] To better demonstrate the disassembly and assembly process of a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, this embodiment proposes a method for disassembling and assembling a high-quality pelletizer rubber roller that can be quickly disassembled and assembled, including the following steps:

[0055] Step 1: Fix the connecting sleeve 21 onto the mounting shaft 4: First, put the connecting sleeve 21 onto the mounting shaft 4, then find the position of the threaded hole 43, and fix the fixing plate 27 to the threaded hole 43 with bolts to realize the installation of the connecting sleeve 21 on the mounting shaft 4;

[0056] Step 2: Fix the roller body 11 to both sides of the connecting sleeve 21: First, put the rubber roller 1 on the mounting shaft 4, then move the roller body 11 until the first water guide port 114 and the second water guide port 23 are tightly attached. Fix the first flange 115 and the second flange 24 together with bolts to achieve a sealed connection between the first water guide port 114 and the second water guide port 23.

[0057] Step 3: Fix the roller ring 12 to the roller body 11: First, pull the roller ring 12 in the groove 111. At this time, the first guide rod 22 is inserted into the insertion hole 121 until the roller ring 12 is tightly attached to the connecting sleeve 21. Thread the nut onto the first guide rod 22 to limit the movement of the roller ring 12, so that the roller ring 12 can protect the first water guide port 114 and the second water guide port 23.

[0058] Step 4: Fix the fixing sleeve 31 to both ends of the mounting shaft 4: First, put the bushing 36 on the fixing shaft 42 so that the third water guide 39 is aligned with the first water guide 114. Fix the fourth flange 310 to the first flange 115 with bolts to achieve a sealed connection between the third water guide 39 and the first water guide 114. Then fix the bushing 36 to the fixing shaft 42 with bolts.

[0059] Step 5: Seal and connect the second water guide pipe 311 and the first water guide pipe 32: Select a certain number of second water guide pipes 311 according to the length of the assembled rubber roller 1, fix multiple second water guide pipes 311 together through the third flange 34, and then fix them to the first water guide pipe 32 through the third flange 34 to achieve a sealed connection between the first water guide pipe 32 and the second water guide pipe 311.

Step 3: Fix the roller ring (12) onto the roller body (11): First, pull the roller ring (12) in the groove (111). At this time, the first guide rod (22) is inserted into the insertion hole (121) until the roller ring (12) is tightly attached to the connecting sleeve (21). Thread the nut onto the first guide rod (22) to limit the movement of the roller ring (12), so that the roller ring (12) can protect the first water inlet (114) and the second water inlet (23). Step 4: Fix the fixing sleeve (31) to both ends of the mounting shaft (4): First, put the bushing (36) on the fixing shaft (42) so that the third water guide (39) is aligned with the first water guide (114). Fix the fourth flange (310) to the first flange (115) with bolts to achieve a sealed connection between the third water guide (39) and the first water guide (114). Then fix the bushing (36) to the fixing shaft (42) with bolts. Step 5: Seal and connect the second water guide pipe (311) and the first water guide pipe (32): Select a certain number of second water guide pipes (311) according to the length of the assembled rubber roller (1), fix multiple second water guide pipes (311) together through the third flange (34), and then fix them together with the first water guide pipe (32) through the third flange (34) to achieve a sealed connection between the first water guide pipe (32) and the second water guide pipe (311).
