Description

Technical Field

[0001] This application relates to the field of leather production technology, and in particular to a feeding roller support for a base fabric laminating machine for artificial leather production. Background Technology

[0002] Artificial leather base fabric is the basic material used to make synthetic leather through processes such as latex impregnation, coating, and finishing. Synthetic leather produced from this material has advantages such as ease of processing, isotropic properties, resistance to cracks, stain resistance, water resistance, oil resistance, chemical resistance, light weight, and good uniformity and resilience. During the processing and production of the base fabric, it needs to be laminated using a base fabric laminating machine.

[0003] The published patent document CN210339709U discloses a feeding roller bracket for a base fabric bonding machine used in artificial leather production. The bracket includes a housing, a platform at the top of the housing, and a U-shaped fixing plate at the top of the platform. The bottom of the U-shaped fixing plate is fitted to the top of the platform. A feeding roller is located on the inner side of the U-shape of the U-shaped fixing plate. A second rotating rod is inserted into the inner cavity of the feeding roller and is fixedly connected to the feeding roller. Both ends of the second rotating rod are fixedly connected to the inner side of the U-shape of the U-shaped fixing plate. In this device, the feeding roller is rigidly connected to the U-shaped fixing plate via the second rotating rod. Changing the fabric roll requires disassembling the rotating rod and other components, making the operation complex. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a feeding roller support for a base fabric laminating machine for artificial leather production, which overcomes the deficiencies of existing technologies and aims to solve the problem of the cumbersome process of changing fabric rolls in existing devices.

[0005] To achieve the above objectives, this application provides the following technical solution: a feeding roller bracket for a base fabric bonding machine for artificial leather production, comprising a platform, a support frame fixedly installed on the upper surface of the platform, a placement groove opened at the top of the support frame, a feeding roller placed at the top of the placement groove, a roll of base fabric on the feeding roller, a fixed frame fixedly installed on one side of the upper surface of the platform located on the support frame, a rotating shaft arranged inside the fixed frame, a motor for driving the rotating shaft to rotate fixedly installed on the outer wall of the fixed frame, a movable groove opened at the end of the rotating shaft away from the motor, a fixed rod fixedly connected inside the movable groove, a movable block rotatably sleeved on the outer wall of the fixed rod located inside the movable groove, leveling seats symmetrically arranged on both outer walls of the rotating shaft, a limit block slidably inserted inside the leveling seat, the movable block fixedly connected to the rotating shaft through the limit block, and the end of the movable block away from the rotating shaft fixedly connected to the feeding roller.

[0006] By adopting the above technical solution, a slot is opened on the top of the support frame to place the feeding roller. The sliding insertion design of the limiting block and the leveling seat forms a mechanical interlock. The movable block is fixedly connected to the rotating shaft through the limiting block. The rotating shaft is driven by a motor to rotate synchronously, thereby realizing the feeding of the base fabric roll. When the base fabric roll needs to be replaced, the operator can manually slide and remove the limiting block, so that the feeding roller can rotate around the fixed rod through the movable block. The operator only needs to lift the feeding roller vertically to complete the loading and unloading, avoiding the cumbersome operation of traditional bolt fixing or bushing disassembly, and realizing the rapid replacement of the base fabric roll.

[0007] As a preferred technical solution of this application, a positioning ring is fixedly sleeved on one side of the outer surface of the feeding roller, and an abutment ring is slidably sleeved on the other side of the outer surface of the feeding roller. The base fabric roll is slidably sleeved on the outer surface of the feeding roller and located between the positioning ring and the abutment ring. A fixing ring is threadedly connected to the outer surface of the feeding roller outside the abutment ring.

[0008] By adopting the above technical solution, the positioning ring is fixedly sleeved on one side of the feeding roller to form a rigid barrier, which limits the initial installation position of the base fabric roll. Rotating the fixing ring can push the abutment ring to move towards the positioning ring, forming an axial clamping force on the base fabric roll, thus clamping and fixing the base fabric roll on the feeding roller.

[0009] As a preferred technical solution of this application, the positioning ring is provided with a plurality of connecting blocks on the side near the base fabric roll, and the side wall of the base fabric roll is provided with connecting grooves for the connecting blocks to be inserted.

[0010] By adopting the above technical solution, the connecting block is inserted into the connecting groove on the side wall of the base fabric roll to form a mechanical fit, so that the rotational torque of the feeding roller is directly transmitted to the base fabric roll and acts on the base fabric inside it, avoiding relative sliding between the base fabric roll and the feeding roller during high-speed feeding, and ensuring feeding synchronization.

[0011] As a preferred technical solution of this application, the limiting block is designed as a T-shaped structure, with a mounting hole through the end of its upper surface away from the T-head. A bolt is slidably inserted into the mounting hole, and a nut is threaded onto the lower end of the bolt.

[0012] By adopting the above technical solution, when the limiting block extends to the outside through the leveling seat, the bolt and threaded nut are slidably inserted into the mounting hole to form a blocking structure, ensuring that the limiting block will not accidentally come out of the leveling seat.

[0013] As a preferred technical solution of this application, the movable block has a through square hole for the limiting block to pass through, and the two outer walls of the movable block abut against the two inner walls of the movable groove.

[0014] By adopting the above technical solution, the square hole and the limiting block form a rigid connection, ensuring that the rotational torque of the motor-driven rotating shaft can be transmitted to the moving block without loss, thereby driving the feeding roller to rotate.

[0015] As a preferred technical solution of this application, a bearing is rotatably sleeved on the outer wall of the rotating shaft near the motor. The bearing is fixedly installed inside the fixed frame, and the rotating shaft extends through the fixed frame through the bearing to the outside and is fixedly connected to the output end of the motor.

[0016] By adopting the above technical solution and setting bearings, the rotating shaft can rotate flexibly inside the fixed frame under the drive of the motor.

[0017] As a preferred technical solution of this application, the two outer walls of the fixing frame are fixedly connected with support feet near the bottom, and the support feet are designed with a triangular structure.

[0018] By adopting the above technical solutions, the overall stability and anti-tipping ability of the fixing frame are improved.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, a slot is opened on the top of the support frame to place the feeding roller. The sliding insertion design of the limiting block and the leveling seat forms a mechanical interlock. The movable block is fixedly connected to the rotating shaft through the limiting block. The rotating shaft is driven by a motor to rotate synchronously, thereby realizing the feeding of the base fabric roll. When the base fabric roll needs to be replaced, the operator can manually slide and remove the limiting block, so that the feeding roller can rotate around the fixed rod through the movable block. The operator only needs to lift the feeding roller vertically to complete the loading and unloading, avoiding the cumbersome operation of traditional bolt fixing or bushing disassembly, and realizing the quick replacement of the base fabric roll.

[0021] 2. In this utility model, the positioning ring is fixedly sleeved on one side of the feeding roller to form a rigid barrier, which limits the initial installation position of the base fabric roll. Rotating the fixing ring can push the abutment ring to move towards the positioning ring, forming an axial clamping force on the base fabric roll, clamping and fixing the base fabric roll on the feeding roller. The connecting block on the positioning ring is inserted into the connecting groove on the side wall of the base fabric roll to form a mechanical fit, so that the rotational torque of the feeding roller is directly transmitted to the base fabric roll and acts on the base fabric inside it, avoiding relative sliding between the base fabric roll and the feeding roller during high-speed feeding, and ensuring feeding synchronization.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 4As shown, this embodiment provides a feeding roller bracket for a base fabric bonding machine for artificial leather production, including a platform 1. A support frame 21 is fixedly installed on the upper surface of the platform 1. A placement groove 22 is opened on the top of the support frame 21, and a feeding roller 9 is placed on the top of the placement groove 22. A base fabric roll 11 is arranged on the feeding roller 9. A fixed frame 2 is fixedly installed on one side of the upper surface of the platform 1, located on the support frame 21. A rotating shaft 4 is arranged inside the fixed frame 2. A motor 5 for driving the rotating shaft 4 to rotate is fixedly installed on the outer wall of the fixed frame 2. A movable groove 6 is opened at the end of the rotating shaft 4 away from the motor 5. A fixed rod 7 is fixedly connected inside the movable groove 6. A movable block 8 is rotatably sleeved on the outer wall of the fixed rod 7 inside the movable groove 6. Leveling seats 14 are symmetrically arranged on both outer walls of the rotating shaft 4. The inner surface of the leveling seat 14... The movable block 8 is fixedly connected to the rotating shaft 4 via the limit block 15. The end of the movable block 8 away from the rotating shaft 4 is fixedly connected to the feeding roller 9. In use, the feeding roller 9 is placed in the placement groove 22. The sliding insertion design of the limit block 15 and the leveling seat 14 forms a mechanical interlock. The movable block 8 is fixedly connected to the rotating shaft 4 via the limit block 15. The rotating shaft 4 is driven to rotate by the motor 5, which drives the feeding roller 9 to rotate synchronously, thereby realizing the feeding of the base fabric roll 11. When the base fabric roll 11 needs to be replaced, the operator can manually slide and remove the limit block 15, so that the feeding roller 9 can rotate around the fixed rod 7 via the movable block 8. The operator only needs to lift the feeding roller 9 vertically to complete the loading and unloading, realizing the quick replacement of the base fabric roll 11.

[0031] In this embodiment, as Figure 1 and 4 As shown, a positioning ring 10 is fixedly sleeved on one side of the outer surface of the feeding roller 9, and an abutment ring 12 is slidably sleeved on the other side of the outer surface of the feeding roller 9. The base fabric roll 11 is slidably sleeved on the outer surface of the feeding roller 9 and located between the positioning ring 10 and the abutment ring 12. A fixing ring 13 is threadedly connected to the outer side of the abutment ring 12 on the outer surface of the feeding roller 9. In use, the positioning ring 10 is fixedly sleeved on one side of the feeding roller 9 to form a rigid barrier, which limits the initial installation position of the base fabric roll 11. Rotating the fixing ring 13 can push the abutment ring 12 to move towards the positioning ring 10, forming an axial clamping force on the base fabric roll 11, thus clamping and fixing the base fabric roll 11 on the feeding roller 9.

[0032] In this embodiment, as Figure 1 and 4As shown, the positioning ring 10 has several connecting blocks 19 on one side near the base fabric roll 11. The side wall of the base fabric roll 11 has a connecting groove 20 for the connecting blocks 19 to be inserted. In use, the connecting blocks 19 are inserted into the connecting groove 20 on the side wall of the base fabric roll 11 to form a mechanical fit, so that the rotational torque of the feeding roller 9 is directly transmitted to the base fabric roll 11 and acts on the base fabric inside it, avoiding relative sliding between the base fabric roll 11 and the feeding roller 9 during high-speed feeding, and ensuring feeding synchronization.

[0033] In this embodiment, as Figure 2 and 3 As shown, the limiting block 15 is designed with a T-shaped structure. A mounting hole 1501 is provided at the end of its upper surface away from the T-head. A bolt 16 is slidably inserted into the mounting hole 1501. A nut 17 is threaded onto the lower end of the bolt 16. In use, when the limiting block 15 extends to the outside through the leveling seat 14, the bolt 16 slidably inserted into the mounting hole 1501 and the threaded nut 17 form a blocking structure to ensure that the limiting block 15 will not accidentally come out of the leveling seat 14.

[0034] In this embodiment, as Figure 3 and 4 As shown, the interior of the movable block 8 has a square hole 801 through which the limiting block 15 passes. The outer walls on both sides of the movable block 8 abut against the inner walls on both sides of the movable groove 6. In use, the square hole 801 and the limiting block 15 form a rigid connection, ensuring that the rotational torque of the rotating shaft 4 driven by the motor 5 can be transmitted to the movable block 8 without loss, thereby driving the feeding roller 9 to rotate.

[0035] In this embodiment, as Figure 2 and 3 As shown, a bearing 3 is rotatably sleeved on the outer wall of the rotating shaft 4 near the motor 5. The bearing 3 is fixedly installed inside the fixed frame 2. The rotating shaft 4 extends through the fixed frame 2 through the bearing 3 to the outside and is fixedly connected to the output end of the motor 5. In use, by setting the bearing 3, the rotating shaft 4 can rotate flexibly inside the fixed frame 2 under the driving action of the motor 5.

[0036] In this embodiment, as Figure 1 As shown, support feet 18 are fixedly connected to the outer walls of both sides of the fixed frame 2 near the bottom. The support feet 18 are designed with a triangular structure, which improves the overall stability and anti-tipping ability of the fixed frame 2 during use.

[0037] The working principle of this utility model is as follows: When using the feeding roller bracket of the base fabric bonding machine for artificial leather production according to this application, when the fabric needs to be changed, the operator first loosens the nut 17 and pulls the bolt 16 out of the limit block 15, and then manually removes the limit block 15. At this time, the operator can vertically lift the feeding roller 9 and loosen the fixing ring to disassemble and replace the old base fabric roll 11. After the feeding roller 9 is replaced with the new base fabric roll 11, the fixing ring 13 is rotated to push the abutment ring 12 to move towards the positioning ring 10, clamping and fixing the base fabric roll 11 on the feeding roller 9. At this time, the operator can slowly lower the feeding roller 9 and place it on the support frame 21. Then, the limit block 15 is re-inserted into the leveling seat 14 to form a mechanical interlock, fixing the movable block 8 and the rotating shaft 4 together. Finally, the motor 5 is started to drive the rotating shaft 4 to rotate and drive the feeding roller 9 to rotate synchronously, thereby realizing the feeding of the base fabric roll 11.
