Description

Technical Field

[0001] This utility model relates to the field of PE cooling mat production technology, specifically a polyethylene rattan flattening and cooling device. Background Technology

[0002] Polyethylene rattan mats are very tough, do not dissolve in water, are soft and cool, and have excellent moisture absorption and perspiration wicking properties. After washing, they are disinfected at high temperatures to effectively prevent mold growth. They are a new type of material that can replace traditional mats. To ensure the comfort of using polyethylene mats, the flatness and cooling effect of polyethylene rattan are particularly important.

[0003] Existing polyethylene rattan leveling and cooling devices use multiple sets of guide rollers (such as the first guide roller, the second guide roller, and the receiving roller) to form a serpentine path, causing the rattan to be arranged in an "S" or "Z" shape within the cooling water tank. The rattan is in contact with the cooling water, and cooling is performed simultaneously with leveling. However, there is no additional guiding and limiting mechanism. The pulling of the rattan during the conveying process can easily cause lateral displacement of the rattan, affecting the leveling effect of the polyethylene rattan and ultimately impacting the quality of the finished polyethylene rattan product. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a polyethylene rattan leveling and cooling device. With the rapid adjustment and position locking of the limiting cylinder, it can meet the limiting requirements of different quantities of polyethylene rattan during the conveying process, ensure the smooth progress of the polyethylene rattan leveling work, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyethylene rattan flattening and cooling device, including a flattening table, a cooling chamber in the middle of the flattening table, two conveying rollers rotatably connected in the middle of the flattening table, and a limiting mechanism.

[0006] The limiting mechanism includes a limiting cylinder, a sliding groove, a sliding block, and a locking port. The limiting cylinders are slidably connected to the outer surfaces of adjacent conveyor rollers. The interior of each limiting cylinder is provided with a uniformly distributed sliding groove, and a sliding block is slidably connected inside each sliding groove. A locking post is fixedly connected to one end of each sliding block near the center of the adjacent conveyor roller. The outer surfaces of each conveyor roller are provided with uniformly distributed locking ports, and the locking posts are inserted into radially adjacent locking ports. The left end of the outer surface of each limiting cylinder is provided with a guide groove. An observation port is provided between each sliding block and the limiting cylinder. The outer surfaces of each conveyor roller are provided with uniformly distributed scale strips. The limiting cylinder allows for rapid adjustment and position locking, meeting the limiting requirements of different quantities of polyethylene rattan during the conveying process and ensuring the smooth operation of the polyethylene rattan leveling work.

[0007] Furthermore, the limiting mechanism also includes an Archimedean spiral groove, a drive disk, an Archimedean spiral rib, a rotating ring, and a rotating groove. The Archimedean spiral grooves are all located at the right end of the sliding block. A rotating groove is provided in the middle of the outer arc surface of the drive disk. A rotating ring is fixedly connected to the right end of the inner arc surface of the limiting cylinder. The rotating rings are rotatably connected to the adjacent rotating grooves. An Archimedean spiral rib is fixedly connected to the left end of the drive disk. The Archimedean spiral grooves located in the same vertical plane are all engaged with the same Archimedean spiral rib, providing driving force for locking the position of the limiting cylinder and the conveying roller.

[0008] Furthermore, the outer surface of the conveying roller is provided with uniformly distributed rib grooves, and the inner wall of the limiting cylinder is fixedly connected with uniformly distributed sliding ribs. The sliding ribs are slidably connected to the adjacent rib grooves to provide guidance and limitation for the lateral movement of the limiting cylinder.

[0009] Furthermore, the upper end of the cooling chamber is rotatably connected to a symmetrically distributed leveling roller one, the lower end of the cooling chamber is rotatably connected to a symmetrically distributed leveling roller three, and the middle part of the cooling chamber is rotatably connected to a leveling roller two. The two leveling rollers one, two leveling rollers three, and leveling roller two are distributed in an M-shape. The front and rear ends of the surface of the leveling platform are rotatably connected to auxiliary rollers to realize the transmission of polyethylene rattan. At the same time, the M-shaped distribution of leveling rollers realizes the pulling of polyethylene rattan, thereby achieving a leveling effect.

[0010] Furthermore, a control box is provided on the right side of the flattening platform. Inside the control box is a controller, the input terminal of which is electrically connected to an external power source to control various electrical appliances.

[0011] Furthermore, a cooling cover is connected to the middle of the upper surface of the flat platform by evenly distributed bolts. A water inlet pipe is fixedly connected to the middle of the cooling cover. A cooling pipe is provided at the lower end of the water inlet pipe. A nozzle is provided at the lower end of the cooling pipe. The upper end of the water inlet pipe is connected to the outlet of an external water pump. The input end of the external water pump is electrically connected to the output end of the controller to realize the spray cooling of the polyethylene rattan.

[0012] Furthermore, a water outlet pipe is provided at the lower end of the right side surface of the cooling chamber, and an electric valve is provided in the middle of the water outlet pipe. The input end of the electric valve is electrically connected to the output end of the controller to control the discharge of water.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This polyethylene rattan flattening and cooling device has the following advantages:

[0014] The drive disc, through the meshing connection of Archimedes spiral ribs and Archimedes spiral grooves, enables the sliding block to move in a centered manner, thereby achieving stable insertion and separation of the locking pin and the corresponding locking port. It also has self-locking properties, improving the stability of the position locking of the limiting cylinder and the conveying roller. Finally, the rapid adjustment and position locking of the limiting cylinder meet the limiting requirements of different quantities of polyethylene rattan during the conveying process, ensuring the smooth progress of the polyethylene rattan leveling work.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: a polyethylene rattan flattening and cooling device, including a flattening table 1, a cooling chamber 2 in the middle of the flattening table 1, two conveying rollers 3 rotatably connected in the middle of the flattening table 1, a control box 13 on the right side of the flattening table 1, a controller 14 inside the control box 13, the input end of the controller 14 being electrically connected to an external power supply, and also including a limiting mechanism 4.

[0023] Limiting mechanism 4: It includes limiting cylinder 41, sliding groove 42, sliding block 43, and locking port 48. The limiting cylinder 41 is slidably connected to the outer surface of the adjacent conveyor roller 3. The interior of the limiting cylinder 41 is provided with evenly distributed sliding grooves 42. The sliding block 43 is slidably connected inside the sliding groove 42. (The sliding block 43 is slidably connected to the guide rail on the inner wall of the sliding groove 42 through a sliding rib groove, ensuring that the sliding block 43 can only slide radially). The center of the circle of the sliding block 43 located inside the same limiting cylinder 41 is located on the central axis of the limiting cylinder 41. The end of the sliding block 43 closest to the center of the adjacent conveyor roller 3 is fixedly connected to a locking post. The outer surface of the conveyor roller 3 is provided with evenly distributed locking ports 48. The locking posts are inserted into the radially adjacent locking ports 48. The outer surface of the conveyor roller 3 is provided with a guide groove 15 on the left end. An observation port is provided between the sliding block 43 and the limiting cylinder 41. The outer surface of the conveyor roller 3 is provided with evenly distributed scale bars 18. The scales of the scale bars 18 are all in the same vertical plane as the central axis of the adjacent locking port 48. The central axis of the observation port is parallel to and in the same vertical plane as the central axis of the adjacent locking pin. Personnel can observe the scales of the scale bars 18 through the observation ports. When the observation port coincides with the scale of the scale bar 18, the locking pin coincides with the central axis of the corresponding locking port 48. Only then can the sliding block 43 be driven to accurately insert the locking pin into the locking port 48. The limiting mechanism 4 also includes an Archimedes spiral groove 44, a drive disc 45, and an Archimedes spiral rib 46. Rotary rings 47 and grooves 49, and Archimedes spiral grooves 44 are all located at the right end of the sliding block 43. Rotary grooves 49 are located in the middle of the outer arc surface of the drive disc 45. Rotary rings 47 are fixedly connected to the right end of the inner arc surface of the limiting cylinder 41. Each rotating ring 47 is rotatably connected to an adjacent groove 49. (The drive disc 45 is also movably sleeved outside the conveyor roller 3, and the rotation of each rotating ring 47 with an adjacent groove 49 provides support for the drive disc 45 to rotate within the limiting cylinder 41.) Archimedes spiral ribs 46 are fixedly connected to the left end of each drive disc 45. Archimedes spiral grooves 44 located in the same vertical plane are engaged with the same Archimedes spiral rib 46. (The connection method between Archimedes spiral grooves 44 and Archimedes spiral ribs 46 is the existing three-jaw chuck.) (The middle chuck is connected to the flat thread). The outer surface of the conveyor roller 3 is provided with uniformly distributed rib grooves 17. The inner wall of the limiting cylinder 41 is fixedly connected with uniformly distributed sliding ribs 16. The sliding ribs 16 are slidably connected to the adjacent rib grooves 17. Due to the sliding guidance of the sliding ribs 16 and rib grooves 17, the locking post is always aligned with the locking opening 48 located on the same conveyor roller 3 and in a straight line. This ensures that after the sliding position is determined, the locking post and 48 will not be angularly misaligned and can be perfectly matched and inserted. According to the guiding and limiting requirements of the polyethylene rattan to be conveyed, the limiting cylinder 41 is first slid laterally. The sliding ribs 16 inside the limiting cylinder 41 slide laterally inside the corresponding rib grooves 17, providing sliding support and guiding and limiting functions for the limiting cylinder 41.When the guide groove 15 on the outer surface of the limiting cylinder 41 reaches the desired position, the lateral movement of the limiting cylinder 41 stops. Then, one hand presses down on the limiting cylinder 41 to limit its position, while the other hand rotates the drive disc 45 on the right side of the limiting cylinder 41. The rotation of the drive disc 45 drives the adjacent Archimedes spiral ribs 46 to rotate. Under the meshing action of the Archimedes spiral groove 44 and the Archimedes spiral ribs 46, the sliding blocks 43 inside the limiting cylinder 41 all move towards the center of the conveyor roller 3 within their corresponding sliding grooves 42. The movement of the sliding blocks 43 drives the adjacent locking pins to move towards the center of the conveyor roller 3. When the locking pins are all inserted into the corresponding locking ports 48, the rotation of the drive disc 45 stops. At this time, the insertion of the locking pins into the adjacent locking ports 48 locks the lateral position of the limiting cylinder 41. This principle is used to adjust the position of each limiting cylinder 41.

[0024] Among them: the upper end of the cooling chamber 2 is rotatably connected to a symmetrically distributed leveling roller 5, the lower end of the cooling chamber 2 is rotatably connected to a symmetrically distributed leveling roller 7, the middle part of the cooling chamber 2 is rotatably connected to a leveling roller 6, the two leveling rollers 5, the two leveling rollers 7 and the leveling roller 6 are distributed in an M-shape, and the front and rear ends of the upper surface of the leveling table 1 are rotatably connected to auxiliary rollers 8.

[0025] The cooling shroud 9 is connected to the center of the upper surface of the leveling platform 1 by evenly distributed bolts. A water inlet pipe 10 is fixedly connected to the center of the cooling shroud 9. A cooling pipe 11 is installed at the lower end of the water inlet pipe 10, and evenly distributed nozzles are installed at the lower end of the cooling pipe 11. The upper end of the water inlet pipe 10 is connected to the outlet of an external water pump. The input end of the external water pump is electrically connected to the output end of the controller 14. A water outlet pipe is installed at the lower end of the right side surface of the cooling chamber 2, and a nozzle is installed in the middle of the water outlet pipe. Electric valve 12, the input end of electric valve 12 is electrically connected to the output end of controller 14. The polyethylene rattan passes sequentially through the upper end of the front auxiliary roller 8, the upper end of the front conveyor roller 3, the upper end of the front leveling roller 5, the front end of the front leveling roller 7, the upper end of the leveling roller 6, the rear end of the rear leveling roller 7, the upper end of the rear leveling roller 5, the upper end of the rear conveyor roller 3, and the upper end of the rear auxiliary roller 8. The polyethylene rattan passes through the conveyor roller 3... At the same time, all are located inside the guide groove 15 on the outer arc surface of the limiting cylinder 41. When the polyethylene rattan passes through the leveling roller, it forms a serpentine path inside the cooling chamber 2, so that the polyethylene rattan is arranged in an M-shape inside the cooling chamber 2, which improves the actual cooling path of the polyethylene rattan inside the cooling chamber 2. The relative pulling of the leveling roller on the polyethylene rattan improves the flatness of the polyethylene rattan. At the same time, the controller 14 realizes the operation of the external water pump, which pumps cooling water into the water inlet pipe 10. The cooling water enters the interior of the cooling pipe 11 and is then sprayed out through evenly distributed nozzles. The cooling water sprays onto the surface of the polyethylene rattan. Meanwhile, cooling water accumulates inside the cooling chamber 2, and the polyethylene rattan inside the cooling chamber 2 is submerged in the cooling water, thereby realizing the cooling of the polyethylene rattan. When the cooling water inside the cooling chamber 2 accumulates to a certain level, the controller 14 realizes the operation of the electric valve 12. The electric valve 12 opens, and the cooling water is discharged through the water outlet pipe.

[0026] The working principle of the polyethylene rattan leveling and cooling device provided by this utility model is as follows: During operation, the operator first places the leveling platform 1, cooling chamber 2, and other mechanisms stably in the horizontal working area. After stable placement, according to the guiding and limiting requirements of the polyethylene rattan to be conveyed, the operator first slides the limiting cylinder 41 laterally. The sliding ribs 16 inside the limiting cylinder 41 slide laterally within the corresponding rib grooves 17, providing sliding support and guiding and limiting functions for the limiting cylinder 41. When the guide groove 15 on the outer surface of the limiting cylinder 41 reaches the required position, the operator stops moving the limiting cylinder 41 laterally, and then the operator presses the limiting cylinder 41 with one hand. 1. While limiting the position of the limiting cylinder 41, use the other hand to rotate the drive disc 45 on the right side of the limiting cylinder 41. The rotation of the drive disc 45 drives the adjacent Archimedes spiral ribs 46 to rotate. Under the meshing action of the Archimedes spiral grooves 44 and the Archimedes spiral ribs 46, the sliding blocks 43 inside the limiting cylinder 41 all move towards the center of the conveyor roller 3 within their corresponding grooves 42. The movement of the sliding blocks 43 drives the adjacent locking pins to move towards the center of the conveyor roller 3. When the locking pins are all inserted into the corresponding locking holes 48, stop rotating the drive disc 45. At this time, the locking pins are inserted into the adjacent locking holes 48. The lateral position of the limiting cylinder 41 is locked, and the position of each limiting cylinder 41 is adjusted based on this principle. Then, the polyethylene rattan passes sequentially through the upper end of the front auxiliary roller 8, the upper end of the front conveyor roller 3, the upper end of the front leveling roller 5, the front end of the front leveling roller 7, the upper end of the leveling roller 6, the rear end of the rear leveling roller 7, the upper end of the rear leveling roller 5, the upper end of the rear conveyor roller 3, and the upper end of the rear auxiliary roller 8. When the polyethylene rattan passes the conveyor roller 3, it is located inside the guide groove 15 on the outer arc surface of the limiting cylinder 41. When the polyethylene rattan passes the leveling roller, it forms a shape inside the cooling chamber 2. The serpentine path allows the polyethylene rattan to be arranged in an M-shape within the cooling chamber 2, improving the actual cooling path of the polyethylene rattan inside the cooling chamber 2. The relative pulling of the flattening rollers on the polyethylene rattan improves its flatness. Simultaneously, the controller 14 activates the external water pump, which pumps cooling water into the inlet pipe 10. The cooling water enters the cooling pipe 11 and is then sprayed out through evenly distributed nozzles, spraying onto the surface of the polyethylene rattan. Meanwhile, cooling water accumulates inside the cooling chamber 2, immersing the polyethylene rattan within it, thus achieving cooling of the polyethylene rattan.

[0027] It is worth noting that the controller 14 disclosed in the above embodiments controls the operation of the external water pump and the electric valve 12 using methods commonly used in the prior art.
