Description

Technical Field

[0001] This utility model relates to the technical field of belt coupling equipment, specifically to a water-cooled heat dissipation mechanism for a belt coupling machine. Background Technology

[0002] Belt splicing machines, also known as belt jointing machines, hot presses, or hot melt machines, are devices that heat-press two belts together to create a seamless connection between two independent belt segments. Common types include PU polyurethane industrial belt splicers, water-cooled fixed industrial belt splicing machines with supports, and PVC conveyor belt splicing machines. They primarily utilize high temperature, pressure, and cooling technology to melt and join lightweight plastic belt joints such as PVC, PU, ​​and PE. Pneumatic hot presses also employ two heating plates simultaneously, utilizing automatic temperature control, pressurized airbags, and an automatic rapid cooling system to meet the physical characteristics and process requirements of various belt materials. Their unique heating design ensures that the processed products have smooth, flexible, and durable joints. Air-cooled belt splicing machines, on the other hand, are compact, small in size, stable in operation, and easy to use, producing smooth and aesthetically pleasing belts with no obvious traces at the joints, improving both appearance and strength. The price of belt splicing machines varies depending on the specifications and type, ranging from several hundred yuan to tens of thousands of yuan.

[0003] Publication number CN209504944U discloses a water-cooled belt conveyor. The upper mold machine has an upper pressure plate pushed by an upper airbag, and the lower mold machine has a fixed lower pressure plate. The upper pressure plate is connected to the bottom of an upper aluminum plate, which contacts an upper heating element; the lower pressure plate is connected to the top of a lower aluminum plate, which contacts a lower heating element; circulating cooling water channels are provided in both the upper and lower aluminum plates; lower pressure strips are provided on the left and right sides of the lower mold machine, and are fixedly connected to the lower mold machine. First locking screws are connected to the front and rear sides of the lower pressure strips. The system includes an upper pressure bar with first locking grooves on its front and rear sides, and a first locking nut threaded onto the first locking screw. A second locking screw is connected to the front and rear sides of the lower mold machine, and a second locking groove is located on the front and rear sides of the top of the upper mold machine. A second locking nut is threaded onto the second locking screw. Water cooling is used to achieve rapid cooling after belt connection. However, this technology only has cooling water channels inside the upper and lower aluminum plates, resulting in uneven belt cooling. This causes color differences between the belt center and outer perimeter due to temperature variations, thus requiring further modification of the technology. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a water-cooled heat dissipation mechanism for a belt conveyor, addressing the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled heat dissipation mechanism for a belt conveyor, comprising a frame and an upper mold machine and a lower mold machine connected to the frame. The upper mold machine is provided with an upper pressure plate pushed by an airbag assembly, and the lower mold machine is provided with a fixed lower pressure plate. Both the upper and lower pressure plates are provided with water-cooling plates for the installation of a first water-cooling channel. The feature is that water-cooling pipes are provided on both sides of the upper and lower pressure plates located on the cold water plate, and a second cold water channel is provided in the water-cooling pipes. One end of the water-cooling pipe is connected to the other end, which is provided with a water inlet pipe.

[0006] Using the above technical solution, the upper and lower pressure plates are not only equipped with water-cooled plates for the installation of the first water-cooling channel, but also with water-cooling pipes on both sides of the water-cooling plates. The water-cooling pipes contain a second cold water channel, with one end connected and the other end connected to a water inlet pipe. The second cold water channel in the water-cooling pipe further enhances cooling and can better cover all parts of the belt, including the center and the outer perimeter, avoiding temperature differences caused by uneven cooling, and thus effectively preventing color difference problems in the belt.

[0007] The water-cooled heat dissipation mechanism of the belt conveyor mentioned above can be further configured as follows: the upper mold machine includes an upper hanging cover, the upper hanging cover is fixedly connected to the upper pressure plate, a first mounting cavity for installing water-cooled pipes is formed between the upper hanging cover and the upper pressure plate, the water-cooled pipes include a first water pipe fixedly installed on both sides of the upper pressure plate and a second water pipe fixedly installed on both sides of the lower pressure plate, and a buffer mechanism is provided between the first water pipe and the upper hanging cover to buffer when the upper hanging cover is pressed down.

[0008] Using the above technical solution, the upper cover is connected to the upper pressure plate, and the two form a first installation cavity for the water-cooled pipe. The water-cooled pipe is divided into a first water pipe fixedly installed on both sides of the upper pressure plate and a second water pipe fixedly installed on both sides of the lower pressure plate. The buffer mechanism set between the first water pipe and the upper cover can effectively buffer the impact force generated by the downward pressure when the upper cover is pressed down during equipment operation, reduce damage to components such as the upper pressure plate and the first water pipe, extend the service life of key components of the equipment, and reduce the maintenance cost and failure rate of the equipment.

[0009] The water-cooled heat dissipation mechanism of the belt conveyor described above can be further configured as follows: the buffer mechanism includes several connecting columns disposed above the first water pipe, the bottom of the upper cover is provided with a movable shaft, the connecting columns are sleeved on the movable shaft to enable the movable shaft to move axially within the connecting columns, and a first elastic element is sleeved on the outer periphery of the connecting columns.

[0010] By adopting the above technical solution, the movable shaft at the bottom of the upper cover cooperates with the connecting column sleeved on it, so that the movable shaft can move axially within the connecting column. When the equipment is running and the upper cover is pressed down, the first elastic element will be compressed and deformed, converting the impact force generated by the downward pressure into elastic potential energy and storing it. This avoids the impact force from directly acting on the first water pipe and the upper pressure plate and other components, thereby effectively reducing the damage to these components and extending the service life of the equipment.

[0011] The water-cooled heat dissipation mechanism of the belt conveyor mentioned above can be further configured as follows: the lower mold machine includes a lower base plate, the lower pressure plate is disposed above the lower base plate, a second mounting cavity for the second water pipe is formed between the lower pressure plate and the lower base plate, the bottom of the second water pipe is provided with a fixing column, one end of the fixing column is fixedly connected to the second water pipe and the other end is fixedly connected to the lower base plate.

[0012] By adopting the above technical solution, a second mounting cavity is formed between the lower pressure plate and the lower base plate of the lower mold machine. The fixing column at the bottom of the second water pipe is fixedly connected to the second water pipe at one end and to the lower base plate at the other end, which ensures the stability of the second water pipe during operation.

[0013] The water-cooled heat dissipation mechanism of the belt conveyor mentioned above can be further configured as follows: the upper mold machine also includes an upper mold body, the top of the upper mold body is fixedly installed with an mounting plate for mounting a second elastic element, the second elastic element is disposed on both sides of the upper mold body, the upper hanging cover is provided with a suspension plate connected to the other end of the second elastic element on both sides, the upper hanging cover is suspended at the bottom of the upper mold body, a third mounting cavity is formed between the upper mold body and the upper hanging cover, and the airbag assembly is disposed in the third mounting cavity.

[0014] Using the above technical solution, the second elastic element is set on both sides of the upper mold body and connected to the suspension plates on both sides of the upper cover, so that the upper cover can be suspended at the bottom of the upper mold body. At the same time, when the airbag assembly is activated, the impact force generated during the downward or reset process of the upper cover can be effectively absorbed and buffered by the second elastic element. The third mounting cavity formed between the upper mold body and the upper cover is used to install the airbag assembly, so that it can push the upper pressure plate downward.

[0015] The water-cooled heat dissipation mechanism of the belt coupling machine described above can be further configured as follows: the airbag assembly includes an airbag fixing cover disposed in the third mounting cavity, the airbag fixing cover is provided with an airbag that presses down on the upper pressure plate after being inflated, and airbag pressure plates are provided between the airbag and the upper cover and between the airbag and the airbag fixing cover.

[0016] Using the above technical solution, the airbag can press down on the upper pressure plate after inflation, and generate pressure through the elastic deformation of the airbag. Compared with the traditional rigid structure pressure, this pressure application method is more uniform and gentle, which can effectively avoid damage caused by excessive pressure on the upper pressure plate and extend the service life of the upper pressure plate. Airbag pressure plates are provided between the airbag and the upper cover and between the airbag and the airbag fixing cover, which further enhances the connection stability between the airbag and the surrounding components.

[0017] The water-cooled heat dissipation mechanism of the belt conveyor mentioned above can be further configured as follows: heat-insulating density board and felt board are provided between the water-cooled plate and the upper shroud and between the water-cooled plate and the lower base plate; a heating mechanism for heating the upper pressure plate and the lower pressure plate is provided between the felt board and the water-cooled plate; the lower mold also includes a lower mold body fixedly installed on the upper end of the frame; the base plate is set on the upper end of the lower mold body; and the upper mold body and the lower mold body are respectively provided with a first locking structure and a second locking structure for locking the upper mold body and the lower mold body during processing.

[0018] Using the above technical solution, the heat insulation density board and felt board set between the water-cooled plate and the upper cover and lower base plate can effectively block heat transfer, prevent the heat generated by the heating mechanism from being lost to other parts of the equipment, and reduce energy loss. The heating mechanism set between the felt board and the water-cooled plate can specifically heat the upper pressure plate and the lower pressure plate. The first locking structure and the second locking structure set at both ends of the upper mold body and the lower mold body can firmly lock the two during processing, avoiding displacement of the upper and lower mold bodies due to vibration or external force during processing.

[0019] The water-cooled heat dissipation mechanism of the belt conveyor mentioned above can be further configured as follows: the first locking structure includes a first connecting shaft fixedly installed in the lower machine mold body, the first connecting shaft passing through the upper machine mold body to enable the upper machine mold body to move vertically back and forth along the first connecting shaft, the top of the upper machine mold body is provided with a sliding groove for the first locking block to slide through, the first connecting shaft is provided with a first abutting block at the end away from the lower machine mold body, the first connecting shaft is provided with a first annular groove at the bottom of the first abutting block, the first locking block is provided with a first engaging groove that engages with the first annular groove when the upper and lower machine mold bodies are locked, and the upper and lower ends of the upper machine mold body are provided with through holes for the first abutting block to pass through so that the first abutting block can pass through the through holes when the upper and lower machine mold bodies are unlocked.

[0020] Using the above technical solution, the first connecting shaft, which is fixedly installed in the lower mold body, passes through the upper mold body, allowing the upper mold body to move vertically back and forth along the first connecting shaft. The sliding groove at the top of the upper mold body is slidably connected to the first locking block. When locking the upper and lower mold bodies, the first locking block is slid to allow the first snap-fit ​​groove to snap into the first annular snap-fit ​​groove on the first connecting shaft, thereby achieving a firm lock between the upper and lower mold bodies. When it is necessary to release the lock, the through holes opened at both ends of the upper mold body allow the first abutment block to pass through the through holes, facilitating the smooth separation of the upper and lower mold bodies.

[0021] The water-cooled heat dissipation mechanism of the belt conveyor described above can be further configured as follows: the second locking structure includes a second connecting shaft disposed at the end of the lower mold body away from the first connecting shaft, the end of the second connecting shaft being hinged to the lower mold body, the second connecting shaft passing through the upper mold body, a second abutting block disposed at the end of the second connecting shaft away from the lower mold body, a second locking block being detachably connected to the top of the upper mold body, the second locking block having a second snap-fit ​​groove, a second annular snap-fit ​​groove being formed between the second abutting block and the upper mold body for snap-fitting of the second snap-fit ​​groove, and an opening for the second connecting shaft to rotate being provided on one side of both the upper and lower mold bodies.

[0022] Using the above technical solution, the end of the second connecting shaft is hinged to the lower mold body and passes through the upper mold body. When the equipment is performing belt splicing processing, the second annular groove formed between the upper mold bodies engages with the second locking groove on the second locking block. When the locking state is released, the second locking block is disassembled, and the second connecting shaft is rotated toward the opening direction to release the locking state of the upper mold body and the lower mold body.

[0023] The water-cooled heat dissipation mechanism of the aforementioned belt conveyor can be further configured as follows: the frame is provided with a workbench fixedly installed with the lower mold body and a truss connected to the upper mold body. The truss is provided with a chain capable of vertical reciprocating movement. The chain is fixedly connected to the top of the upper mold body through a connecting block. A guide block is provided on the side of the upper mold body away from the second connecting shaft. A guide shaft is provided between the workbench and the truss. The guide block is sleeved on the guide shaft. A control box capable of controlling the lifting and lowering of the chain is also provided on one side of the frame.

[0024] Using the above technical solution, a workbench fixedly installed on the lower mold body and a truss connected to the upper mold body are provided on the frame. A chain on the truss that can move vertically back and forth is fixedly connected to the top of the upper mold body through a connecting block, so that the upper mold body can move back and forth vertically under the drive of the chain. A guide block set on the side of the upper mold body away from the second connecting shaft is sleeved on the guide shaft between the workbench and the truss, which plays a guiding and limiting role, ensuring the straightness and stability of the upper mold body during vertical movement. A control box set on one side of the frame can control the lifting and lowering of the chain, and the operator can flexibly adjust the position of the upper mold body according to actual needs.

[0025] The beneficial effects of this utility model are as follows: water cooling pipes are set on both sides of the water cooling plate, and the second cold water channel in the water cooling pipe further enhances the cooling and increases the cooling area, avoiding temperature differences caused by uneven cooling, and thus effectively preventing color difference problems in the belt.

Detailed Implementation

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] like Figure 1-6The present invention provides the following technical solution: a water-cooled heat dissipation mechanism for a belt conveyor, comprising a frame 1 and an upper mold machine 2 and a lower mold machine 3 connected to the frame 1. The upper mold machine 2 contains an upper pressure plate 4 pushed by an airbag assembly, and the lower mold machine 3 contains a fixed lower pressure plate 5. Both the upper and lower pressure plates 4 and 5 are equipped with water-cooled plates 7 for mounting a first water-cooling channel 6. Water-cooling pipes are located on both sides of the upper and lower pressure plates 4 and 5, and each water-cooling pipe contains a second cold water channel 9. One end of each water-cooling pipe is connected to the other end, which has a water inlet pipe 10. In addition to the water-cooled plates 7 for mounting the first water-cooling channel 6, the upper and lower pressure plates 4 and 5 also have water-cooling pipes on both sides of the water-cooling plates 7. Each water-cooling pipe contains a second cold water channel 9, with one end connected to the other end, which has a water inlet pipe 10. The second cold water channel 9 in the water-cooling pipe further enhances cooling and can better cover all parts of the belt, including the center and outer perimeter, avoiding temperature differences due to uneven cooling and effectively preventing color differences in the belt. The upper mold machine 2 includes an upper hanging cover 11, which is fixedly connected to an upper pressure plate 4. A first mounting cavity 12 for installing water-cooled pipes is formed between the upper hanging cover 11 and the upper pressure plate 4. The water-cooled pipes include first water pipes 13 fixedly installed on both sides of the upper pressure plate 4 and second water pipes 14 fixedly installed on both sides of the lower pressure plate 5. A buffer mechanism is provided between the first water pipes 13 and the upper hanging cover 11 to buffer the downward pressure of the upper hanging cover 11. The upper hanging cover 11 is connected to the upper pressure plate 4, and the first mounting cavity 12 for installing water-cooled pipes is formed between them. The water-cooled pipes are divided into first water pipes 13 fixedly installed on both sides of the upper pressure plate 4 and second water pipes 14 fixedly installed on both sides of the lower pressure plate 5. The buffer mechanism provided between the first water pipes 13 and the upper hanging cover 11 can effectively buffer the impact force generated by the downward pressure when the upper hanging cover 11 is pressed down during equipment operation, reducing damage to components such as the upper pressure plate 4 and the first water pipes 13, extending the service life of key components, and reducing equipment maintenance costs and failure rates. The buffer mechanism includes several connecting columns 15 positioned above the first water pipe 13. A movable shaft 16 is located at the bottom of the upper cover 11. The connecting columns 15 are sleeved on the movable shaft 16, allowing the movable shaft 16 to move axially within the connecting columns 15. A first elastic element 17 is sleeved on the outer periphery of the connecting columns 15. The movable shaft 16 at the bottom of the upper cover 11 cooperates with the connecting columns 15 sleeved on it, enabling the movable shaft 16 to move axially within the connecting columns 15. When the equipment operates and the upper cover 11 presses down, the first elastic element 17 is compressed and deformed, converting the impact force generated by the downward pressure into elastic potential energy for storage. This prevents the impact force from directly acting on components such as the first water pipe 13 and the upper pressure plate 4, thereby effectively reducing damage to these components and extending the service life of the equipment.The lower mold machine 3 includes a lower base plate 18, and a lower pressure plate 5 is disposed above the lower base plate 18. A second mounting cavity 19 for the second water pipe 14 is formed between the lower pressure plate 5 and the lower base plate 18. A fixing post 20 is provided at the bottom of the second water pipe 14. One end of the fixing post 20 is fixedly connected to the second water pipe 14, and the other end is fixedly connected to the lower base plate 18. The lower pressure plate 5 and the lower base plate 18 of the lower mold machine 3 form the second mounting cavity 19. The fixing post 20 at the bottom of the second water pipe 14 is fixedly connected at one end to the second water pipe 14 and at the other end to the lower base plate 18, ensuring the stability of the second water pipe 14 during operation. The upper mold machine 2 also includes an upper mold body 21. A mounting plate 23 for mounting the second elastic element 22 is fixedly installed on the top of the upper mold body 21. The second elastic element 22 is located on both sides of the upper mold body 21. Suspension plates 24 connected to the other ends of the second elastic elements 22 are provided on both sides of the upper hanging cover 11. The upper hanging cover 11 is suspended at the bottom of the upper mold body 21. A third mounting cavity 25 is formed between the upper mold body 21 and the upper hanging cover 11. The airbag assembly is located within the third mounting cavity 25. The second elastic element 22 is located on both sides of the upper mold body 21 and connected to the suspension plates 24 on both sides of the upper hanging cover 11, allowing the upper hanging cover 11 to be suspended at the bottom of the upper mold body 21. Simultaneously, when the airbag assembly moves, the impact force generated during the downward or resetting process of the upper hanging cover 11 can be effectively absorbed and buffered by the second elastic element 22. The third mounting cavity 25 formed between the upper mold body 21 and the upper hanging cover 11 is used to install the airbag assembly, enabling it to push the upper pressure plate 4 downward. The airbag assembly includes an airbag fixing cover 26 disposed within the third mounting cavity 25. An airbag 27, when inflated, presses down on the upper pressure plate 4 within the airbag fixing cover 26. Airbag pressure plates 28 are provided between the airbag 27 and the upper cover 11, and between the airbag 27 and the airbag fixing cover 26. After inflation, the airbag 27 can press down on the upper pressure plate 4, generating pressure through the elastic deformation of the airbag 27. Compared to traditional rigid structure pressure application, this pressure application method is more uniform and gentle, effectively avoiding damage caused by excessive local pressure on the upper pressure plate 4, thus extending the service life of the upper pressure plate 4. The presence of airbag pressure plates 28 between the airbag 27 and the upper cover 11, and between the airbag 27 and the airbag fixing cover 26, further enhances the connection stability between the airbag 27 and surrounding components.

When the equipment is performing belt splicing processing, the second annular groove 43 formed between the upper mold bodies 21 engages with the second locking groove 42 on the second locking block 41. To release the lock, the second locking block 41 is removed, and the second connecting shaft 39 is rotated toward the opening 44 to release the lock of the upper mold body 21 and the lower mold body 31. The frame 1 is equipped with a worktable 45 fixedly installed on the lower mold body 31 and a truss 46 connected to the upper mold body 21.
