Description

Technical Field

[0001] The utility model relates to the technical field of base cloth production, and more specifically, to a tentering and shaping device for base cloth production. Background Art

[0002] A stenter is a pneumatically controlled, lift-and-hold insulated door panel setting machine widely used in the finishing of various textiles, including woven and knitted fabrics. Stentering is a process in fabric production designed to relax stress in stretched fibers, improving their crystallinity and the stability of various properties while reducing their boiling water shrinkage. This process involves subjecting the fibers to heat for a certain period of time, allowing the macromolecules that make up the fibers to gain sufficient energy for mobility and adjust the "positions" of their chain segments, minimizing the energy content of the fiber structure. A stenter is a device used to complete these processes. The effective width of the fabric after stentering is generally referred to as the width.

[0003] Patent document CN202120345221.8 discloses a stenter setting machine, which includes an operating table and a stenter assembly. Two stenter assemblies are symmetrically arranged along the length of the operating table. The stenter assembly includes a bidirectional screw rod, a limit rod, a support seat, and a slide. The limit rod and the bidirectional screw rod are both extended along the width of the operating table. The limit rod is parallel to the bidirectional screw rod. The support seat is provided at both ends of the limit rod. One end of the bidirectional screw rod is connected to a drive motor. Two slides are passed through the limit rod. The two slides are equidistant from the center of the length of the limit rod. The end of the slide away from the limit rod is screwed to the bidirectional screw rod. One end of the bidirectional screw rod is a positive thread and the other end is a negative thread. The positive and negative threads respectively cooperate with the corresponding slides. The slide is connected to a clamping assembly for clamping the fabric. This application has the advantage of facilitating the control of the width of the fabric after stentering.

[0004] However, during the use of the above-mentioned document, when processing leather base fabrics of different colors, the staff is required to clean the guide rollers to avoid color mixing, but the cleaning efficiency is low and the work intensity of the staff is high.

[0005] In response to the above problems, a stretching and shaping device for leather-based fabric production with the existing publication number CN220942027U is provided, which includes a mounting seat, a support frame provided on the mounting seat, the support frame being rotatably connected to a first guide roller and a second guide roller, a first cleaning block being slidably connected above the first guide roller in the support frame, and the first cleaning block being detachably connected to a first cleaning sponge; a second cleaning block being slidably connected below the second guide roller in the support frame, and the second cleaning block being detachably connected to a second cleaning sponge.

[0006] The first guide roller and the second guide roller of the shaping device of the above solution can convey the leather base cloth, the first cleaning sponge can quickly clean the first guide roller, and the second cleaning sponge can quickly clean the second guide roller.

[0007] The first cleaning sponge and the second cleaning sponge in the above scheme can clean the first guide roller and the second guide roller in time, and the first cleaning sponge and the second cleaning sponge can slide out of the support frame, but in the process of cleaning the first guide roller and the second guide roller, water and alcohol still need to be absorbed to clean the first guide roller and the second guide roller, and the water will be squeezed out when the first cleaning sponge and the second cleaning sponge come into contact with the first guide roller and the second guide roller, which will cause the first guide roller and the second guide roller to be contaminated with sewage generated by the outflowing water, thereby still reducing the cleaning efficiency of the first guide roller and the second guide roller, and at the same time affecting the efficiency of the base fabric shaping. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a tentering and shaping device for base cloth production, which can facilitate the cleaning of the guide roller to improve the efficiency of base cloth transmission and tentering and shaping.

[0009] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: A stretching and shaping device for base cloth production, comprising a base, a first support frame and a second support frame symmetrically arranged at both ends of the base, and a fixed rod arranged between the first support frame and the second support frame, a plurality of guide rollers are arranged between the first support frame and the second support frame, a motor for driving the guide rollers to rotate is provided on the first support frame, and a gap for the base cloth to pass through is opened between adjacent guide rollers, the guide roller is rotatably connected to the second support frame at one end away from the motor, a first fixed shaft and a second fixed shaft are respectively provided at both ends of the guide roller, the first rotating shaft is fixedly connected to the output shaft of the motor, and the second rotating shaft is rotatably connected to the second support frame, the first fixed shaft and the second fixed shaft are respectively detachably connected to the first rotating shaft and the second rotating shaft, and the fixed rod is provided with a driving component for driving the second support frame away from the first support frame.

[0010] By adopting the above technical solution, the base fabric is transmitted under the action of the guide roller, and the rotation of the first rotating shaft is driven by the action of the motor to drive the first fixed rod and the guide roller to rotate. At the same time, the second fixed shaft and the second rotating shaft at the other end of the guide roller will rotate with the rotation of the first rotating shaft to realize the transmission of the base fabric that needs to be stretched and shaped. The first rotating shaft and the second rotating shaft rotate on the first support frame and the second support frame respectively. The base fabric is coated with pigments of various colors, which will remain on the surface of the guide roller during the contact with the guide roller. In order to prevent the base fabric of another color from being mixed with the color when being transmitted, the staff needs to remove the guide roller from the first support frame and the second support frame for cleaning or replacement. Therefore, the staff first needs to use the action of the driving component to move the second support frame away from The second support frame is moved closer to the first support frame through the action of the driving assembly, and finally, the guide roller is driven to rotate under the action of the motor, so that the staff can clean and replace the guide roller in time to ensure the working efficiency of the guide roller, thereby ensuring the efficiency of the base cloth forming.

[0011] The utility model is further configured as follows: a first slot for the first fixed shaft to be inserted into is provided on the first rotating shaft, elastic bodies are provided at both ends of the first fixed shaft, a first slot for the elastic body to be inserted into is provided on the inner wall of the first slot, and the first slot is communicated with the outside.

[0012] By adopting the above technical solution, when the second support frame moves away from the first support frame, the second rotating shaft is also separated from the second fixed shaft. Then the staff needs to retract the protruding elastic body into the first slot through the first slot and then pull the guide roller so that the elastic body is in contact with the inner wall of the first slot and slides along the inner wall of the first slot until the first fixed shaft is completely separated from the first slot. The first fixed shaft and the first rotating shaft are separated. At this time, the staff can clean, repair or replace the guide roller. After the processing is completed, the first fixed shaft of the guide roller is inserted into the first slot again, and the elastic body is squeezed by the first rotating shaft and the inner wall of the first slot and shrinks. When the elastic body is continuously inserted with the first fixed shaft and slides to the position corresponding to the first slot, the elastic body is clamped into the first slot under the action of its own elastic force to be fixed, thereby achieving the fixation of the first fixed shaft and the guide roller. The structure is simple and convenient for the staff to operate, and it also improves the efficiency of the guide roller processing, improves the working efficiency of the guide roller, and improves the efficiency of the base cloth width setting.

[0013] The utility model is further configured as follows: the elastic body includes a first spring arranged on the first fixed shaft and a fixed block arranged on the first spring.

[0014] By adopting the above technical solution, when the guide roller is cleaned and contacted and the first fixed shaft and the first rotating shaft are installed and the elastomer is inserted into the first slot, the fixed block will be squeezed by the inner wall of the first slot and squeeze the first spring and cause the first spring to contract. The first fixed shaft continues to slide until the position of the elastomer moves to a position corresponding to the first slot, and the first spring will push the fixed block into the first slot under the action of its own elastic force. At this time, the first fixed shaft and the first rotating shaft are fixed, and the guide roller is fixed. Then, the second fixed shaft and the second rotating shaft at the other end of the guide roller are fixed together to realize the reinstallation of the guide roller. The simple structure is convenient for the operation of the staff and also convenient for cleaning the guide roller, thereby improving the service life and work efficiency of the guide roller.

[0015] The utility model is further configured as follows: an arc surface is provided on one end of the fixing block away from the first spring.

[0016] By adopting the above technical solution, the arrangement of the arc surface ensures that the interior of the first rotating shaft will not be worn when the fixing block contacts the inner wall of the first slot.

[0017] The utility model is further configured as follows: a groove is provided inside the first fixed shaft for the first spring and the fixed block to move.

[0018] By adopting the above technical solution, when the first fixed shaft is inserted into the first rotating shaft, the first spring and the fixed block on the first fixed shaft will be retracted into the groove, thereby ensuring that the gap between the first fixed shaft and the first rotating shaft becomes smaller, ensuring that the first fixed shaft is more stable when inserted into the first rotating shaft, reducing the shaking of the first fixed shaft in the first rotating shaft when the first fixed shaft and the first rotating shaft are fixed together, ensuring the tightness of the connection between the two, and also playing a certain protective role for the first spring, preventing the first spring from being greatly bent during the extension and contraction process, thereby affecting the service life of the first spring and the guide roller.

[0019] The utility model is further configured as follows: a second slot for the second fixed shaft to be inserted into is provided on the second rotating shaft, both ends of the second fixed shaft are rotatably connected with hooks, and the hooks are arranged on the second fixed shaft at an angle, a second slot for the hook to be inserted into is provided on the inner wall of the second slot, and a push spring is abutted between the hook and the second fixed shaft.

[0020] When the guide roller needs to be disassembled, the driving assembly pushes the second support frame away from the first support frame. During this process, the second rotating shaft on the second support frame will gradually move away from the second fixed shaft, and the hook located in the second rotating shaft will be squeezed by the second clamping groove and the inner wall of the second slot to squeeze the push spring. When the hook is completely disengaged from the second rotating shaft, the second fixed shaft and the second rotating shaft are separated. Then the staff separates the first fixed shaft at the other end of the guide roller from the first rotating shaft to realize the disassembly of the guide roller. After the cleaning is completed, The first fixed axis of the guide roller and the first rotating axis are fixed together, and then the second rotating axis is gradually moved close to the second fixed axis of the guide roller through the action of the driving component, so that the second slot of the second rotating axis will be aligned with the second fixed axis, so that the hook will be inserted into the second slot and rotated on the second fixed axis by being squeezed by external force, and the pushing spring between the two hooks will shrink by being squeezed by external force, and when the hook moves to the position of the second slot, the hook will gradually be stuck in the second slot under the action of the pushing spring to be fixed, thereby achieving fixation of the second fixed axis, and the structure is simple and convenient for the staff to operate.

[0021] The utility model is further configured as follows: the driving assembly includes a cylinder arranged on the first support frame, and the protruding end of the cylinder is fixedly connected to the second support frame.

[0022] By adopting the above technical solution, when the guide roller needs to be disassembled, repaired, replaced or cleaned, the staff first needs to drive the cylinder to extend, so that the second support frame will gradually move away from the first support frame and the guide roller under the action of the cylinder, thereby realizing the separation of the second fixed axis and the second rotating axis of the guide roller. After the guide roller is cleaned, the guide roller is installed together with the first support frame and the second support frame, which is convenient for the staff to handle.

[0023] The present invention is further configured as follows: a T-shaped block is provided at one end of the second support frame close to the base, and a sliding groove for the T-shaped block to slide is provided on the base.

[0024] By adopting the above technical solution, the T-block will not be separated from the slide groove when sliding in the slide groove, and the second support frame will not be separated from the base during the sliding process, thereby improving the stability of the second support frame when it is driven to move by the cylinder, ensuring that the second support frame can be quickly moved out under the action of the cylinder and can also be quickly moved back to the initial position.

[0025] In summary, the utility model has the following beneficial effects: the staff can conveniently clean the guide roller in time to improve the efficiency of base cloth transmission and stretching and shaping, and the guide roller can be disassembled from the first support frame and the second support frame for timely replacement, maintenance and cleaning, which will not affect the efficiency of guide roller cleaning and normal working efficiency.

[0037] A first slot 12 is provided on the first rotating shaft 8 for the first fixed shaft 14 to be inserted into, and an elastomer is provided at both ends of the first fixed shaft 14. A first card slot 13 is provided on the inner wall of the first slot 12 for the elastomer to be inserted into, and the first card slot 13 is communicated with the outside world. The elastomer includes a first spring 16 provided on the first fixed shaft 14 and a fixed block 15 provided on the first spring 16.

[0038] An arc surface is provided on one end of the fixing block 15 away from the first spring 16 .

[0039] The first fixed shaft 14 is provided with a groove 17 for the first spring 16 and the fixing block 15 to move. When the first fixed shaft 14 is inserted into the first rotating shaft 8, the first spring 16 and the fixing block 15 on the first fixed shaft 14 will be retracted into the groove 17, which can ensure that the gap between the first fixed shaft 14 and the first rotating shaft 8 becomes smaller, ensuring that the first fixed shaft 14 is more stable when inserted into the first rotating shaft 8, reducing the shaking of the first fixed shaft 14 in the first rotating shaft 8 when the first fixed shaft 14 and the first rotating shaft 8 are fixed together, ensuring the tightness of the connection between the two, and also playing a certain protective role for the first spring 16, preventing the first spring 16 from generating a large bending during the extension and contraction process, thereby affecting the service life of the first spring 16 and the guide roller 6.

[0040] The second rotating shaft 9 is provided with a second slot 21 for the second fixed shaft 18 to be inserted into. Both ends of the second fixed shaft 18 are rotatably connected with hooks 19, and the hooks 19 are arranged on the second fixed shaft 18 at an angle. A second groove 22 for the hook 19 to be inserted into is provided on the inner wall of the second slot 21, and a push spring 20 is abutted between the hook 19 and the second fixed shaft 18.

[0041] Working principle: the base cloth is transmitted under the action of the guide roller 6, and the rotation of the first rotating shaft 8 is driven by the action of the motor 7 to drive the first fixed rod 4 and the guide roller 6 to rotate. At the same time, the second fixed shaft 18 and the second rotating shaft 9 at the other end of the guide roller 6 will rotate with the rotation of the first rotating shaft 8 to realize the transmission of the base cloth that needs to be stretched and shaped. The first rotating shaft 8 and the second rotating shaft 9 rotate on the first support frame 2 and the second support frame 3 respectively. The base cloth is coated with pigments of various colors, which will remain on the surface of the guide roller 6 during the contact with the guide roller 6. In order to prevent the base cloth of another color from being mixed with the color when being transmitted, the staff needs to remove the guide roller 6 from the first support frame 2 and the second support frame 3 for cleaning or replacement. Therefore, the staff first needs to use the action of the driving component to move the second support frame 3 away from the first support frame Frame 2, during the process, the second rotating shaft 9 will gradually separate from the second fixed shaft 18, realizing the disassembly of the second fixed shaft 18, and then the staff will manually separate the first fixed shaft 14 and the first rotating shaft 8 at the other end of the guide roller 6 to realize the disassembly of the guide roller 6. At this time, the guide roller 6 can be cleaned or replaced to prevent the guide roller 6 from mixing with the base cloth and affecting the efficiency of the base cloth width setting. Then, the staff will fix the first fixed shaft 14 and the second fixed shaft 18 to the first rotating shaft 8 and the second rotating shaft 9 respectively, and then use the action of the driving component to move the second support frame 3 close to the first support frame 2. Finally, under the action of the motor 7, the guide roller 6 is driven to rotate. The staff can clean and replace the guide roller 6 in time to ensure the working efficiency of the guide roller 6, thereby also ensuring the efficiency of the base cloth width setting.

[0042] When the second support frame 3 is away from the first support frame 2, the second rotating shaft 9 is also separated from the second fixed shaft 18. Then the staff needs to retract the protruding elastic body into the first slot 12 through the first card slot 13 and then pull the guide roller 6, so that the elastic body fits the inner wall of the first slot 12 and slides along the inner wall of the first slot 12 until the first fixed shaft 14 is completely separated from the first slot 12, thereby realizing the separation of the first fixed shaft 14 and the first rotating shaft 8. At this time, the staff can clean, repair or replace the guide roller 6, and then replace the guide roller 6 with the first fixed shaft 14 after the processing is completed. A fixed shaft 14 is inserted into the first slot 12, and the elastomer is squeezed and contracted by the first rotating shaft 8 and the inner wall of the first slot 12. When the elastomer is continuously inserted along with the first fixed shaft 14 and slides to a position corresponding to the first card slot 13, the elastomer will be stuck in the first card slot 13 under the action of its own elastic force to be fixed, thereby achieving the fixation of the first fixed shaft 14 and the guide roller 6. The structure is simple and convenient for the staff to operate, and it also improves the efficiency of the guide roller 6 processing, improves the working efficiency of the guide roller 6, and improves the efficiency of the base cloth width shaping.

[0043] When the guide roller 6 is cleaned and in contact, the first fixed shaft 14 and the first rotating shaft 8 are installed and the elastomer is inserted into the first slot 12, the fixed block 15 will be squeezed by the inner wall of the first slot 12 and squeeze the first spring 16 and cause the first spring 16 to contract. When the first fixed shaft 14 continues to slide until the position of the elastomer moves to the position corresponding to the first slot 13, the first spring 16 will push the fixed block 15 into the first slot 13 under the action of its own elastic force. At this time, the first fixed shaft 14 and the first rotating shaft 8 are fixed, and the guide roller 6 is fixed. Then the second fixed shaft 18 and the second rotating shaft 9 at the other end of the guide roller 6 are fixed together to achieve the reinstallation of the guide roller 6. The simple structure is convenient for the operation of the staff and also convenient for cleaning the guide roller 6, thereby improving the service life and work efficiency of the guide roller 6.

[0044] When it is necessary to disassemble the guide roller 6, the driving assembly pushes the second support frame 3 away from the first support frame 2. During this process, the second rotating shaft 9 on the second supporting frame 3 will gradually move away from the second fixed shaft 18, and the hook 19 located in the second rotating shaft 9 will be squeezed by the second card slot 22 and the inner wall of the second slot 21 to squeeze the push spring 20. When the hook 19 is completely disengaged from the second rotating shaft 9, the second fixed shaft 18 and the second rotating shaft 9 are separated. Then the staff separates the first fixed shaft 14 at the other end of the guide roller 6 from the first rotating shaft 8 to realize the disassembly of the guide roller 6. After the cleaning is completed, the first fixed shaft 14 of the guide roller 6 is removed. The shaft 14 is fixed together with the first rotating shaft 8, and then the second rotating shaft 9 is gradually approached to the second fixed shaft 18 of the guide roller 6 through the action of the driving component, and the second slot 21 of the second rotating shaft 9 will be aligned with the second fixed shaft 18, so that the hook 19 will be inserted into the second slot 21 and squeezed by external force and rotate on the second fixed shaft 18, and the pushing spring 20 between the two hooks 19 will be squeezed by external force and shrink. When the hook 19 moves to the position of the second slot 22, the hook 19 will gradually be stuck in the second slot 22 under the action of the pushing spring 20 to be fixed, thereby realizing the fixation of the second fixed shaft 18, and the structure is simple and convenient for the staff to operate.

[0045] When the guide roller 6 needs to be disassembled, repaired, replaced or cleaned, the staff first needs to drive the cylinder 5 to extend, so that the second support frame 3 will gradually move away from the first support frame 2 and the guide roller 6 under the action of the cylinder 5, thereby realizing the separation of the second fixed axis 18 of the guide roller 6 from the second rotating axis 9. After the guide roller 6 is cleaned, the guide roller 6 is installed together with the first support frame 2 and the second support frame 3, which is convenient for the staff to handle. At the same time, the T-block 10 will not separate from the slide groove 11 when sliding in the slide groove 11, and the second support frame 3 will not separate from the base 1 during the sliding process, thereby improving the stability of the second support frame 3 when it is driven to move by the cylinder 5, ensuring that the second support frame 3 can be quickly moved out under the action of the cylinder 5, and can also be quickly moved back to the initial position.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
