Description

Technical Field

[0001] This utility model relates to the field of Oxford cloth processing technology, and in particular to a calendering device for Oxford cloth processing. Background Technology

[0002] In the calendering process of Oxford cloth, the Oxford cloth is first released by the unwinding mechanism. After being preheated by the heating mechanism, the cloth enters the calendering mechanism. In the calendering mechanism, the Oxford cloth is subjected to the squeezing and stretching action of the calendering rollers. Simultaneously, the heating softens the fabric, making it easier to deform according to the shape and pressure requirements of the calendering rollers, thereby adjusting the thickness, density, and improving surface smoothness. After calendering, the cooling mechanism cools and sets the Oxford cloth, maintaining its post-calendering shape and properties. Finally, the winding mechanism winds the processed Oxford cloth into a roll.

[0003] When it is necessary to frequently change sleeves with different textures or functions to produce a variety of Oxford cloth products, the sleeves in the calendering mechanism need to be replaced. In the existing technology, changing the sleeve requires disassembling multiple parts and using special tools for complex operations, which will lead to a significant increase in production changeover time. Utility Model Content

[0004] To reduce production changeover time, this application provides a calendering apparatus for processing Oxford cloth.

[0005] The calendering apparatus for processing Oxford cloth provided in this application adopts the following technical solution:

[0006] A calendering apparatus for processing Oxford cloth includes a frame and a calendering mechanism. The calendering mechanism includes a plurality of calendering rolls and a plurality of sleeves. The plurality of calendering rolls are rotatably connected to the frame. Each of the plurality of calendering rolls is provided with a guide groove, and a plug-in block is slidably connected in each of the plurality of guide grooves. The plurality of sleeves correspond to the plurality of calendering rolls and can be sleeved on the corresponding calendering rolls. Each of the plurality of sleeves has a guide block slidably connected in the guide groove on its inner wall. The guide block is provided with a plug-in groove that can engage with the plug-in block. When the sleeve is sleeved on the calendering roll, the guide block is located in the guide groove, and the plug-in block engages with the plug-in groove.

[0007] By adopting the above technical solution, the sleeve can be sleeved on the calendering roll and fixed by the cooperation of the guide block and the guide groove and the snap-fit ​​of the plug block and the plug groove; the guide block slides in the guide groove, and the snap-fit ​​of the plug block and the plug groove reduces the possibility of axial or circumferential displacement of the sleeve during the calendering process, which facilitates sleeve replacement, precise positioning and reduces production changeover time.

[0008] Preferably, the plug block is tapered from both ends to the middle along its length.

[0009] By adopting the above technical solution, when installing the sleeve onto the calender roll, the end of the insert block is easier to align and insert into the insert slot in the guide groove, reducing the difficulty of alignment and insertion. Similarly, when the sleeve needs to be disassembled, it is easier to pull the insert block out of the insert slot, improving the efficiency of sleeve replacement.

[0010] Preferably, the end of the calender roll near the insertion block is provided with a first abutting plate, and when the sleeve is sleeved on the calender roll, one end of the sleeve in the length direction abuts against the first abutting plate.

[0011] By adopting the above technical solution, the first abutment plate provides a clear axial positioning reference for the sleeve. The sleeve abuts against the first abutment plate, accurately determining the sleeve's installation position on the calendering roll, ensuring that the sleeve does not move arbitrarily in the axial direction. This ensures the relative positional accuracy between the sleeve and the calendering roll during the calendering process, which is beneficial for improving the stability and consistency of the calendering process and ensuring the stability of the Oxford cloth processing quality.

[0012] Preferably, it also includes a second abutment plate, which is provided with a mating groove. The end of the calender roll away from the first abutment plate in the axial direction is provided with a mating block that can mate with the mating groove. When the second abutment plate is installed on the calender roll, the second abutment plate abuts against the end face of the sleeve away from the first abutment plate.

[0013] By adopting the above technical solution, the second abutting plate is installed by mating with the mating block on the calendering roll through the mating groove, and abuts against the end face of the sleeve away from the first abutting plate. Together with the first abutting plate, it fixes the sleeve from both ends, effectively preventing the sleeve from moving axially during the calendering process, further improving the stability and reliability of the sleeve installation, and ensuring the accuracy and quality of the calendering process.

[0014] Preferably, it also includes a number of bolts, one end of which can be threaded through a second abutment plate and threaded onto the calendering roll.

[0015] By adopting the above technical solution, the bolt connection facilitates installation and disassembly operations for workers and provides strong fastening force to firmly fix the second abutment plate onto the calendering roll. This connection method ensures that the second abutment plate will not loosen or fall off due to external forces during the calendering process, thereby guaranteeing the stability and reliability of the entire device and improving the precision of the calendering process and product quality.

[0016] Preferably, the mating blocks are polygonal in shape.

[0017] By adopting the above technical solution, the polygonal mating block and the mating groove are matched, which can reduce the possibility of the second abutment plate rotating in the circumferential direction relative to the calendering roll.

[0018] Preferably, the outer wall of the sleeve is provided with an anti-slip groove for easy gripping.

[0019] By adopting the above technical solution, the anti-slip groove provides operators with a clear point of force application. When changing the sleeve, the operator can directly grip the groove with their fingers to avoid unstable grip due to the smooth surface of the sleeve. Especially in scenarios where the sleeve needs to be quickly disassembled and assembled to reduce production changeover time, it can greatly improve operating efficiency and reduce the time loss caused by repeatedly adjusting the grip position.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. This utility model, by setting guide blocks and guide grooves, allows the sleeve to be fitted onto the calendering roll, and is fixed by the cooperation of the guide block and the guide groove, as well as the snap-fit ​​of the plug block and the plug groove; the guide block slides in the guide groove, and the snap-fit ​​of the plug block and the plug groove reduces the possibility of axial or circumferential displacement of the sleeve during calendering, which facilitates sleeve replacement, precise positioning, and reduces production changeover time;

[0022] 2. This utility model provides a clear axial positioning reference for the sleeve by setting a first abutting plate. The sleeve abuts against the first abutting plate, accurately determining the sleeve's installation position on the calendering roll, ensuring that the sleeve does not move arbitrarily in the axial direction. This ensures the relative positional accuracy between the sleeve and the calendering roll during the calendering process, which is beneficial for improving the stability and consistency of the calendering process and ensuring the stability of the Oxford cloth processing quality.

[0023] 3. This utility model provides a second abutting plate, which is installed by fitting a groove with a fitting block on the calendering roll. The second abutting plate abuts against the end face of the sleeve away from the first abutting plate and works together with the first abutting plate to fix the sleeve from both ends. This effectively prevents the sleeve from moving axially during the calendering process, further improving the stability and reliability of the sleeve installation and ensuring the accuracy and quality of the calendering process.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0032] This application discloses a calendering apparatus for processing Oxford cloth.

[0033] Reference Figure 5 and Figure 6 This embodiment of a calendering apparatus for processing Oxford cloth includes a frame 1 and a calendering mechanism 2. The calendering mechanism 2 includes a plurality of calendering rollers 3 and a plurality of sleeves 4. The plurality of calendering rollers 3 are rotatably connected to the frame 1. A plurality of guide grooves 5 are formed on the plurality of calendering rollers. The plurality of guide grooves 5 are evenly distributed along the circumference of the calendering rollers 3. Insertion blocks 6 are slidably connected in the plurality of guide grooves 5 along the depth direction of the guide grooves 5. The two ends of the insertion blocks 6 are tapered towards the middle in the length direction. Springs 7 are installed on the insertion blocks 6. The ends respectively abut against the bottom surface of the insertion block 6 and the guide groove 5. The spring 7 always drives the insertion block 6 to slide away from the bottom surface of the guide groove 5. Several sleeves 4 correspond to several calendering rollers 3 respectively. Several sleeves 4 can be sleeved on the corresponding calendering rollers 3. Several sleeves 4 are fixedly connected to the inner walls of several sleeves 4 and can be slidably connected in the guide groove 5. The guide block 8 has an insertion groove 9 that can be engaged with the insertion block 6. When the sleeve 4 is sleeved on the calendering roller 3, the guide block 8 is located in the guide groove 5, and the insertion block 6 is engaged with the insertion groove 9.

[0034] Reference Figure 1 and Figure 2The sleeve 4 can be fitted onto the calendering roll 3 and is fixed by the cooperation of the guide block 8 and the guide groove 5, and the snap-fit ​​of the insertion block 6 and the insertion groove 9. The guide block 8 slides in the guide groove 5, and the snap-fit ​​of the insertion block 6 and the insertion groove 9 reduces the possibility of axial or circumferential displacement of the sleeve 4 during calendering, facilitating the replacement of the sleeve 4, precise positioning, and reducing production changeover time. When installing the sleeve 4 onto the calendering roll 3, the end of the insertion block 6 is easier to align and insert into the insertion groove 9 in the guide groove 5, reducing the difficulty of alignment and insertion. Similarly, when it is necessary to disassemble the sleeve 4, it is easier to pull the insertion block 6 out of the insertion groove 9, improving the efficiency of sleeve 4 replacement.

[0035] Reference Figure 3 and Figure 5 A first abutment plate 10 is fixedly connected to one end of the calender roll 3 near the insertion block 6. When the sleeve 4 is fitted onto the calender roll 3, one end of the sleeve 4 in the length direction abuts against the first abutment plate 10. The first abutment plate 10 provides a clear axial positioning reference for the sleeve 4. The abutment of the sleeve 4 against the first abutment plate 10 can accurately determine the installation position of the sleeve 4 on the calender roll 3, ensuring that the sleeve 4 will not move arbitrarily in the axial direction. This ensures the relative positional accuracy between the sleeve 4 and the calender roll 3 during the calendering process, which is beneficial to improving the stability and consistency of the calendering process and ensuring the stability of the Oxford cloth processing quality.

[0036] Reference Figure 3 and Figure 4 The system also includes a second abutment plate 11, which has a mating groove 12. A mating block 13, polygonal in shape, is located at the end of the calender roll 3 furthest from the first abutment plate 10, and engages with the mating groove 12. When the second abutment plate 11 is installed on the calender roll 3, it abuts against the end face of the sleeve 4 furthest from the first abutment plate 10. The second abutment plate 11, through the mating groove 12, engages with the mating block 13 on the calender roll 3, abutting against the end face of the sleeve 4 furthest from the first abutment plate 10. Together with the first abutment plate 10, it fixes the sleeve 4 from both ends, effectively preventing axial movement of the sleeve 4 during calendering, further improving the stability and reliability of the sleeve 4 installation, and ensuring the precision and quality of the calendering process. The polygonal mating block 13, engaging with the mating groove 12, reduces the possibility of the second abutment plate 11 rotating relative to the calender roll 3 in the circumferential direction.

[0037] Reference Figure 3 and Figure 4It also includes several bolts 14, one end of which can be threaded through a second abutment plate 11 and connected to the calendering roll 3. Using bolts 14 facilitates installation and disassembly by workers and provides strong clamping force to firmly fix the second abutment plate 11 to the calendering roll 3. This connection method ensures that the second abutment plate 11 will not loosen or fall off due to external force during the calendering process, thus guaranteeing the stability and reliability of the entire device and improving the precision of the calendering process and product quality.

[0038] Reference Figure 3 and Figure 6 The outer wall of the sleeve 4 is provided with an anti-slip groove 15 for easy gripping. The anti-slip groove 15 provides the operator with a clear point of force application. When changing the sleeve 4, the operator can directly grip the anti-slip groove 15 with their fingers to avoid unstable grip due to the smooth surface of the sleeve 4. Especially in scenarios where the sleeve 4 needs to be quickly disassembled and assembled to reduce production changeover time, it can greatly improve operating efficiency and reduce the time loss caused by repeatedly adjusting the grip position.

[0039] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
