Description

Technical Field

[0001] This application relates to the field of release paper production, and in particular to a cooling roller replacement structure. Background Technology

[0002] After the release paper has undergone high-temperature drying or coating processes, its surface temperature is relatively high. Cooling rollers are mainly used to cool down the coated release paper to prevent problems such as release paper deformation or resin extrusion caused by high temperature.

[0003] The two ends of the cooling roller are usually mounted on positioning seats. The positioning seats are usually designed according to the size and shape of the cooling roller to ensure that they can firmly support the cooling roller. The cooling roller is usually connected to the positioning seat through bearings to realize the rotation function and ensure that the cooling roller can rotate smoothly. This connection method can not only fix the position of the cooling roller, but also reduce friction during rotation.

[0004] In the prior art, since the positioning seat is usually customized for cooling rollers of specific size and shape to achieve firm support and smooth rotation, when changing cooling rollers of different sizes or types, the positioning seat must be disassembled and replaced first, and then the new cooling roller is installed. This will affect the replacement efficiency of the cooling roller and reduce the practicality of the structure. Utility Model Content

[0005] To reduce the time and physical labor required for replacing cooling rollers, this application provides a cooling roller replacement structure.

[0006] The cooling roller replacement structure provided in this application adopts the following technical solution:

[0007] A cooling roller replacement structure includes two bases, positioning seats respectively mounted on the upper sides of the two bases, and a cooling roller mounted between the two positioning seats. The cooling roller includes a roller and a transmission rod. The transmission rod is fixedly connected to both ends of the roller. Each positioning seat has a positioning component for mounting the transmission rod at its upper end. Two insertion rods are fixedly connected to the lower side of each positioning component. Each positioning seat has a slot for inserting the insertion rods. Each positioning seat has a locking component for locking the insertion rods. Each base has an adjusting component installed on its inner side. One end of each adjusting component is connected to an infusion tube connected to one end of the transmission rod.

[0008] By adopting the above technical solution, firstly, the insertion and locking mechanism of the rod and slot can quickly fix the positioning component, and quickly complete the installation and disassembly of the positioning component without completely removing the positioning seat, reducing the complexity of operation and thus improving the replacement efficiency of the cooling roller; secondly, the adjustment mechanism can quickly connect the infusion tube to the cooling roller, enabling the coolant to circulate inside the cooling roller, improving the practicality and flexibility of the structure.

[0009] Optionally, the positioning component includes a positioning plate and a cover plate. One end of the cover plate is hinged to one end of the upper surface of the positioning plate. The end of the cover plate away from the hinge point is connected to a fastener that is threadedly connected to the positioning plate. A positioning groove is provided between the positioning plate and the cover plate. The inner wall of the positioning groove is rotatably connected to a bearing that is fixedly connected to the outer wall of the transmission rod. The lower surface of the positioning plate is fixedly connected to the upper end of the insertion rod.

[0010] By adopting the above technical solution, the operation steps can be simplified by quickly loading and unloading the bearing and transmission rod through opening and closing the cover plate. The positioning groove and bearing cooperate to ensure the rotational stability of the cooling roller and avoid recalibration during replacement, thereby improving the replacement efficiency of the cooling roller.

[0011] Optionally, the locking component includes a rotating rod, a transmission gear, and two insert plates. The rotating rod is rotatably connected to the inner wall of the positioning seat. The inner wall of the positioning seat has a limiting groove for sliding of the two insert plates, and the limiting groove communicates with two slots. The transmission gear is disposed on the inner wall of the limiting groove and is fixedly connected to the outer wall of the rotating rod. Each of the two insert plates has a toothed groove on an adjacent side that meshes with the outer wall of the transmission gear. Each insert rod has a positioning hole for inserting one end of the insert plate.

[0012] By adopting the above technical solution, the locking component drives two insert plates to be inserted into the positioning holes of two insert rods respectively through the transmission gear and tooth groove, thereby realizing multi-point locking of the structure, improving the stability of the connection between the insert rod and the positioning seat, and the locking or unlocking of the structure can be completed by rotating the rotating rod with one hand, improving the convenience of operation.

[0013] Optionally, the inner wall of the limiting groove is fixedly connected to two limiting blocks, and each limiting block has a limiting plate fixedly connected to the insert plate on one side.

[0014] By adopting the above technical solution, the limiting block and the limiting plate can limit the displacement range of the insert plate, which can not only prevent the insert plate from over-locking or dislodging, but also avoid interference between the limiting plate and the transmission gear, improve the service life of the structure, and ensure locking accuracy and safety.

[0015] Optionally, a knob is fixedly connected to one end of the rotating rod, and a ratchet is fixedly connected to the outer wall of the rotating rod on one side of the knob. A pawl is connected to the outer side of the ratchet, and the end of the pawl facing away from the ratchet is rotatably connected to the positioning seat.

[0016] By adopting the above technical solution, rotating the knob can quickly drive the rotating rod to rotate, providing a convenient manual operation interface. The ratchet and pawl form a one-way locking mechanism to prevent the rotating rod from accidentally reversing and causing the two insert plates to loosen, thereby enhancing the stability of the locking between the structures.

[0017] Optionally, a return spring is fixedly connected to one side of the pawl, and a fixing block fixedly connected to the other end of the return spring is fixedly connected to the positioning seat.

[0018] By adopting the above technical solution, the return spring automatically returns the pawl to the locked position, preventing the pawl from disengaging from the ratchet due to vibration, reducing manual intervention, and improving the practicality of the structure.

[0019] Optionally, the adjusting component includes an electric push rod, a connecting block, and a limiting rod. The electric push rod is fixedly connected to the inner wall of the base. One end of the piston rod of the electric push rod is fixedly connected to one side of the connecting block. The infusion tube is fixedly connected to the inner wall of the connecting block. The limiting rod is fixedly connected to one side of the connecting block, and the connecting rod passes through the inner wall of the base.

[0020] By adopting the above technical solution, the electric push rod drives the connecting block to adjust the position of the infusion tube, which can be adapted to transmission rods of different lengths to achieve automatic adjustment. The limit rod can prevent the connecting block from deviating during the movement, ensuring the accuracy of the connection between the infusion tube and the cooling roller.

[0021] Optionally, each of the infusion tubes is fixedly connected to a rotary joint at its upper end, which is connected to one end of a transmission rod, and each of the infusion tubes is fixedly connected to a fixed joint at its lower end for connecting to a water pipe.

[0022] By adopting the above technical solution, the rotary joint allows the transmission rod to maintain a tight seal with the infusion tube when rotating, and the rotary joint supports quick replacement and can be adapted to different sizes or types of cooling rollers. The fixed joint has a standardized water pipe interface, which can be compatible with different cooling systems and ensures that the coolant circulates without leakage.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. This application enables the rapid installation and disassembly of positioning components and cooling rollers, reducing manual operation time and physical labor consumption, thereby improving the replacement efficiency of cooling rollers and enhancing the practicality of the overall structure.

[0025] 2. This application can automatically adjust the position of the infusion tube, adapt to transmission rods of different lengths, and combine with rotary joints and fixed joints. It can not only ensure the sealing of coolant circulation, but also be compatible with various cooling roller specifications and external water pipe interfaces, achieving quick docking and reducing manual adjustment steps and leakage risks.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a cooling roller replacement structure.

[0034] Reference Figure 1 The cooling roller replacement structure includes two bases 1, which ensure the overall stability of the structure. A positioning seat 2 is fixedly installed on the upper side of each base 1, and a positioning component 3 for fixing the cooling roller 4 is fixedly installed on the upper end of each positioning seat 2. The positioning component 3 is used to fix the cooling roller 4 to the upper ends of the two positioning seats 2. A locking component 6 is provided on the inner side of the positioning seat 2 to fix the positioning component 3, ensuring the stability of the connection between the positioning component 3 and the positioning seat 2. An adjusting component 7 is fixedly connected to the inner wall of each base 1. One end of the adjusting component 7 is equipped with a liquid inlet pipe 8 connected to the cooling roller 4, allowing the coolant to circulate within the inner wall of the cooling roller 4 through the two liquid inlet pipes 8.

[0035] When installing the cooling roller 4, the two positioning parts 3 are fixed to the two positioning seats 2 by the locking part 6, and then the cooling roller 4 is installed between the two positioning parts 3 to complete the installation of the cooling roller 4. When disassembling the cooling roller 4, the positioning parts 3 are unlocked first and then the cooling roller 4 is taken out and replaced. When the positioning parts 3 need to be replaced, the locking part 6 is unlocked so that the positioning parts 3 can be replaced quickly.

[0036] refer to Figure 2 , Figure 3 The positioning component 3 includes a positioning plate 31 and a cover plate 32. One end of the cover plate 32 is hinged to one end of the positioning plate 31, and the other end of the cover plate 32 is threadedly connected to a fastener 34 that is threadedly connected to the positioning plate 31. The fastener 34 is used to lock the cover plate 32 to the upper side of the positioning plate 31. Two insert rods 5 are fixedly connected to the lower end of the positioning plate 31, and the upper end of the positioning seat 2 is provided with slots 21 for inserting two insert plates 63. The connection between the insert rods 5 and the slots 21 is used to improve the stability and convenience of the connection between the top positioning component 3 and the positioning seat 2.

[0037] refer to Figure 2 , Figure 3 The cooling roller 4 includes a roller 41 and two drive rods 42, which are fixed at both ends of the roller 41. The inner walls of both the roller 41 and the two drive rods 42 have channels for the flow of coolant, and these channels are connected to the infusion pipe 8. The drive rods 42 ensure the stability of the roller 41, which contacts the release paper to cool it. A positioning groove 33 is provided between the cover plate 32 and the positioning plate 31 for mounting the drive rods 42. An arc-shaped groove is formed in the middle of the positioning groove 33, and a bearing 43, fixedly connected to the outer wall of the drive rod 42, is rotatably connected to the inner wall of the arc-shaped groove. The connection between the bearing 43 and the positioning groove 33 ensures the stability of the drive rod 42 as it rotates between the positioning plate 31 and the cover plate 32.

[0038] refer to Figure 2 , Figure 3The inner wall of the positioning seat 2 has a limiting groove 22 communicating with two slots 21. The limiting groove 22 is used for the installation of the locking component 6. The locking component 6 includes a rotating rod 61 rotatably connected to the inner wall of the positioning seat 2 and a transmission gear 62 fixedly connected to the outer wall of the rotating rod 61 and disposed in the inner wall of the limiting groove 22. One end of the rotating rod 61 is fixedly connected to a knob 611, which is used to rotate the rotating rod 61 to drive the transmission gear 62 to rotate in the inner wall of the limiting groove 22. Insert plates 63 are installed on both the upper and lower sides of the transmission gear 62 and are slidably connected to the inner wall of the limiting groove 22. The adjacent side of the two insert plates 63 is provided with tooth grooves 631 for meshing with the outer wall of the transmission gear 62. When the transmission gear 62 rotates, it can simultaneously drive the two insert plates 63 to slide in the inner wall of the limiting groove 22. Each insertion rod 5 has two positioning holes 51 for insertion of the insertion plate 63. The connection between the insertion plate 63 and the inner wall of the positioning hole 51 is used to fix the insertion rod 5 to the inner wall of the slot 21, thereby locking the positioning member 3.

[0039] refer to Figure 2 , Figure 3 Each transmission gear 62 has a limiting block 23 fixedly connected to the inner wall of the limiting block on both sides. Each limiting block 23 has a limiting plate 632 fixedly connected to the insert plate 63 on one side. The limiting block 23 is U-shaped and the limiting plate 632 slides in the groove of the limiting block 23 to limit the movement range of the insert plate 63 and prevent the limiting plate 632 from contacting the transmission gear 62.

[0040] refer to Figure 3 , Figure 4 The adjusting component 7 includes an electric push rod 71 fixedly connected to the base 1 and a connecting block 72 fixedly connected to the piston rod of the electric push rod 71. The inner wall of the connecting block 72 is fixedly connected to the lower outer wall of the infusion tube 8. The extension and retraction of the electric push rod 71 can drive the connecting plate to move, thereby quickly adjusting the position of the infusion tube 8. A limiting rod 73, fixedly connected to one side of the connecting block 72, is slidably connected to the inner walls of both ends of each base 1. The limiting rod 73 is used to prevent misalignment of the connecting block 72 during movement. A quick-change rotating joint 81 is installed at the upper end of the infusion tube 8. The rotating joint 81 can be fitted onto one end of the transmission rod 42, ensuring a stable connection between the infusion tube 8 and the transmission rod 42 without affecting the rotation of the transmission rod 42, thus preventing leakage. A fixed joint 82 for connecting the liquid supply pipeline is fixedly connected to the lower end of the infusion tube 8. The fixed joint 82 ensures the stability of the connection between various liquid supply pipelines and the structure, ensuring leak-free circulation of coolant.

[0041] refer to Figure 4 , Figure 5Each rotating rod 61 has a ratchet 9 fixedly connected to one end of its outer wall. Each ratchet 9 is rotatably connected to one side of the positioning seat 2 via the rotating rod 61. Each positioning seat 2 has a pawl 10 rotatably connected to one side to prevent the ratchet 9 from reversing. A return spring 11 is fixedly connected to one side of each pawl 10. A fixing block 12, which is fixedly connected to the positioning seat 2, is fixedly connected to the other end of each return spring 11. The fixing block 12 is used to ensure the stability of the return spring 11, and the return spring 11 is used to ensure the stability of the connection between the pawl 10 and the ratchet 9. When the knob 611 is turned in the forward direction, it drives the rotating rod 61 and the transmission gear 62 to rotate, causing the insert plate 63 to be inserted into the positioning hole 51 of the insert rod 5. The ratchet 9 rotates normally. After the rotation ends, one end of the pawl 10 presses against the teeth of the ratchet 9 to prevent the ratchet 9 from reversing. When it is necessary to remove the insert plate 63 from the insert rod 5, the pawl 10 is pushed upward, causing the return spring 11 to extend until the front end of the pawl 10 disengages from the ratchet 9. Finally, turning the knob 611 in the reverse direction will drive the rotating rod 61 and the transmission gear 62 to rotate in the opposite direction until one end of the insert plate 63 is pushed away from the positioning hole 51, thus unlocking the positioning plate 31.

[0042] The implementation principle of the cooling roller replacement structure in this application embodiment is as follows: When installing the cooling roller 4, firstly, the positioning seat 2 is installed on the base 1, and the base 1 is installed on one side of the release paper coating equipment; secondly, the two insert rods 5 on the lower side of the positioning member 3 are aligned with the slots 21 on the positioning seat 2 and inserted until the lower surface of the positioning plate 31 is in contact with the upper surface of the positioning seat 2; thirdly, the knob 611 is rotated to drive the rotating rod 61 and the transmission gear 62 to rotate, causing the insert plate 63 to slide on the inner wall of the limiting groove 22 until one end of the two insert plates 63 is simultaneously inserted into the slot. The inner wall of the positioning hole 51 of rod 5 is used to fix the positioning part 3, and the meshing state of ratchet 9 and pawl 10 is checked to prevent loosening; the fourth step is to loosen the fastener 34 and open the cover plate 32, put the transmission rods 42 at both ends of the cooling roller 4 into the positioning groove 33, ensure that the bearing 43 is in sync with the arc groove, close the cover plate 32 and tighten the fastener 34; the fifth step is to start the electric push rod 71 to drive the connecting block 72 to move until the rotating joint 81 at the upper end of the infusion tube 8 is connected to one end of the transmission rod 42, completing the connection between the cooling roller 4 and the infusion tube 8, and completing the installation of the cooling roller 4. When replacing the cooling roller 4, the first step is to disconnect the coolant supply and evacuate the coolant from the cooling roller 4; the second step is to control the electric push rod 71 to push the connecting block 72 to move until the rotating joint 81 disengages from the transmission rod 42; the third step is to loosen the fastener 34 and open the cover plate 32 to remove the old cooling roller 4; the fourth step is to replace the positioning part 3 if it is necessary to move the pawl 10 to disengage from the ratchet 9, and then rotate the knob 611 in the opposite direction until the insert plate 63 exits the positioning hole 51, and finally pull the positioning part 3 upward until the insert rod 5 disengages from the slot 21 to complete the removal of the positioning part 3; finally, repeat the above steps to complete the installation of the new positioning part 3 and the new cooling roller 4.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
