Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machines, specifically a fabric lifting mechanism for fabric spreading machines. Background Technology

[0002] A fabric spreading machine uses a beak to spread cylindrical fabric into widths. It is suitable for spreading knitted fabrics. The beak width is adjustable to accommodate fabrics of different diameters. Because the beak of existing vertical spreading machines is located at the highest point of the machine, it is necessary to manually lift one end of the fabric from a low position to a high position and thread it through the beak during spreading. As the fabric is gradually lifted, the amount of fabric suspended in the air gradually increases, resulting in a gradual increase in the weight of the suspended fabric. This not only makes it easy for the fabric to slip out of the hand or for the fabric to be difficult to thread through the beak, but also increases the danger of workers working at heights. Utility Model Content

[0003] The purpose of this utility model is to provide a fabric lifting mechanism for a fabric sizing machine, which overcomes the above-mentioned defects in the prior art.

[0004] According to the present invention, a fabric lifting mechanism for a fabric opening machine includes a first fixed plate, and second fixed plates perpendicular to the first fixed plate are fixed at the upper and lower ends of the first fixed plate. A clamping mechanism for clamping fabric is slidably arranged between the upper and lower second fixed plates.

[0005] The clamping mechanism includes a clamping sleeve, a lifting block, and a clamping wheel. The clamping sleeve has a U-shaped cross-section. The lifting block is fixed on the outer side of the curved part of the clamping sleeve. The lifting block is internally threaded with a screw. The upper and lower ends of the screw are rotatably connected to the upper and lower second fixing plates, respectively. The clamping wheel is slidably connected between the two side walls of the clamping sleeve. When the clamping wheel slides downward, it moves closer to the curved part of the clamping sleeve.

[0006] Preferably, the clamping sleeve has limit grooves on both side walls, the limit grooves gradually move from top to bottom towards the lifting block, the upper end of the limit grooves is open, the clamping wheel has a wheel axle fixed inside, and the two ends of the wheel axle slide in the two limit grooves.

[0007] Preferably, both ends of the axle are fixed with limiting gears, and the outer surfaces of the two side walls of the clamping sleeve are fixed with limiting racks located below the limiting groove and parallel to the limiting groove, and the limiting gears and limiting racks mesh with each other.

[0008] Preferably, a pad is fixed to the inner side of the bent portion of the clamping sleeve, and the pad is made of rubber.

[0009] Preferably, each of the lifting blocks has a slider fixed on one side parallel to the two side walls of the clamping sleeve, and a guide plate located on both sides of the lifting block is fixed between the second fixing plates on the upper and lower sides. The guide plate has vertically distributed guide grooves, and the two sliders are slidably connected to the two guide grooves respectively.

[0010] Preferably, a motor is fixed to the upper surface of the second fixing plate on the upper side, and the upper end of the screw is fixed to the output shaft of the motor.

[0011] The beneficial effects of this utility model are as follows: This utility model is fixed on a vertical fabric spreading machine and located on the lower side of the eagle's beak. It uses clamping wheels and pads to clamp the cylindrical fabric. The motor drives the screw to rotate, causing the clamping mechanism to rise, thereby clamping one end of the cylindrical fabric and lifting it upward to the lower side of the eagle's beak. This makes it easier for workers to thread the fabric into the eagle's beak and reduces the risk of workers working at height. Attached Figure Description

Figure 1 The orientations or positional relationships shown are merely simplified descriptions for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of the fabric lifting mechanism for a fabric spreading machine are described in detail below:

[0019] One embodiment of this utility model:

[0020] Reference Figures 1-3 This utility model provides a fabric lifting mechanism for a fabric opening machine, including a first fixed plate 10, with second fixed plates 11 perpendicular to the first fixed plate 10 fixed at both the upper and lower ends, and a clamping mechanism for clamping the fabric slidably arranged between the upper and lower second fixed plates 11.

[0021] The clamping mechanism includes a clamping sleeve 21, a lifting block 20, and a clamping wheel 23. The clamping wheel 23 is made of rubber. The clamping sleeve 21 has a U-shaped cross-section. The lifting block 20 is fixed on the outer side of the curved part of the clamping sleeve 21. The lifting block 20 is internally threaded with a screw 29. The upper and lower ends of the screw 29 are rotatably connected to the upper and lower second fixing plates 11 respectively. The clamping wheel 23 is slidably connected between the two side walls of the clamping sleeve 21. When the clamping wheel 23 slides downward, it moves closer to the curved part of the clamping sleeve 21.

[0022] Reference Figure 2 , Figure 3 The clamping sleeve 21 has limit grooves 24 on both side walls, which gradually move towards the lifting block 20 from top to bottom. The upper end of the limit grooves 24 is open. A wheel axle 26 is fixed inside the clamping wheel 23. The two ends of the wheel axle 26 slide within the two limit grooves 24. Limit gears 27 are fixed at both ends of the wheel axle 26. Limit racks 25 located below and parallel to the limit grooves 24 are fixed on the outer surfaces of both side walls of the clamping sleeve 21. 7 engages with the limiting rack 25. The inner side of the curved part of the clamping sleeve 21 is fixed with a pad 28, which is made of rubber. When the cylindrical fabric slides downward between the clamping wheel 23 and the pad 28, the friction between the fabric and the clamping wheel 23 causes the clamping wheel 23 to roll downward along the limiting rack 25. This causes the clamping wheel 23 to gradually move closer to the pad 28, thereby clamping the fabric tighter and preventing the fabric from coming off the clamping mechanism.

[0023] Reference Figure 1 , Figure 2The lifting block 20 has a slider 22 fixed on one side of each side wall parallel to the clamping sleeve 21. The guide plate 12 located on both sides of the lifting block 20 is fixed between the second fixing plates 11 on the upper and lower sides. The guide plate 12 has vertically distributed guide grooves 13. The two sliders 22 are slidably connected to the two guide grooves 13 respectively. The upper end of the second fixing plate 11 on the upper side is fixed with a motor 14. The upper end of the screw 29 is fixed to the output shaft of the motor 14.

[0024] When in use, the clamping mechanism is located at the lowest point of the first fixed plate 10. First, the clamping wheel 23 is taken out from the clamping sleeve 21, and the cylindrical fabric is inserted into the pad 28. Then, the clamping wheel 23 is put into the clamping sleeve 21, and the two ends of the wheel axle 26 are inserted into the limiting groove 24. The limiting gear 27 meshes with the limiting rack 25, and the clamping wheel 23 rolls along the limiting rack 25 so that the clamping wheel 23 cooperates with the pad 28 to clamp the fabric.

[0025] Then, the motor 14 is started, causing the screw 29 to rotate, which in turn drives the lifting block 20 to move upward, thereby causing the clamping mechanism to move upward and lift the fabric upward until the fabric moves to the lower side of the eagle beak. Then, the motor 14 is turned off, and the operator takes the fabric out of the clamping sleeve 21 and puts it into the eagle beak.

[0026] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
