Description

Technical Field

[0001] The utility model relates to the technical field of leather unwinding, in particular to a leather dyeing feeding system. Background Art

[0002] PU synthetic leather is also called polyurethane synthetic leather. For the sake of convenience, it is collectively referred to as synthetic leather below. Its surface is made of polyurethane and its back is made of cloth. It is now widely used in the decoration of bags, clothing, shoes, vehicles and furniture.

[0003] In the production process of synthetic leather, lamination is an important step. After lamination, a transparent protective film or a coating of various patterns and colors will be applied to the surface of the synthetic leather, thereby enhancing the performance and appearance of the final product.

[0004] Before the synthetic leather lamination process, workers need to unwind the synthetic leather wound on the roller shaft. For the sake of convenience, the leather winding roller is referred to as the leather winding roller below. When unwinding the synthetic leather, the leather winding roller needs to be placed on the unwinding rack lifted by the crane. The existing unwinding rack includes a bottom plate and vertical plates arranged vertically on both sides of the bottom plate. The top surfaces of the two vertical plates are provided with two sets of rolling parts arranged at intervals and capable of assisting the unwinding of the synthetic leather. When the two ends of the leather winding roller are respectively placed on the rolling parts at the feeding end of the unwinding rack, the roller shaft at the discharging end and other subsequent production equipment are pulled to slowly rotate to realize passive unwinding. When the synthetic leather wound on the leather winding roller at the feeding end of the unwinding rack is about to be unwound, two workers are required to lift the two ends of the leather winding roller respectively, and then move it to the rolling parts at the discharging end of the unwinding roller, and then place the new leather winding roller on the rolling parts at the feeding end of the unwinding rack. Then the workers sew the synthetic leather on the two winding rollers together by needle and thread, so that the synthetic leather can be unwound continuously.

[0005] However, in actual production, since the entire production line is in continuous processing, in the process of moving the leather winding roller that is about to be unwound to the rolling piece at the discharge end, the leather winding roller cannot rotate due to manual operation and is in a state where it cannot be unwound. The subsequent production equipment has been constantly pulling the synthetic leather to move, causing the unwound leather to be in a state of excessive tension, which will not only cause fatigue damage to the leather and affect the appearance quality of the leather, but may also cause the leather to break in severe cases.

[0006] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0007] The utility model provides a leather dyeing feeding system, aiming to solve the problems that the existing leather unwinding roller cannot unwind when moving, causing the leather to be in an over-tensioned state, and is prone to fatigue damage or breakage.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A leather dyeing feeding system comprises a base plate, with the length direction of the base plate as the left-right direction, first vertical plates perpendicular to the base plate are respectively provided on the left and right sides of the front portion of the top surface of the base plate, and second vertical plates perpendicular to the base plate are respectively provided on the left and right sides of the rear portion of the top surface of the base plate, the top surfaces of the first vertical plate and the second vertical plate are both concavely provided with accommodating grooves, each of the accommodating grooves is provided with a rolling assembly for supporting a leather unwinding roller, linear driving mechanisms are respectively provided on the left and right sides of the base plate and are arranged horizontally along the front-back direction, and the two linear driving mechanisms are respectively installed with supporting rolling assemblies which can translate synchronously and move the leather unwinding roller placed on the rolling assembly of the first vertical plate to the rolling assembly of the second vertical plate.

[0011] Furthermore, the above-mentioned supporting rolling assembly includes a movable block installed on the above-mentioned linear driving mechanism, a mounting plate is uprightly provided on the top surface of the above-mentioned movable block, a vertically arranged cylinder is fixedly installed on the side of the above-mentioned mounting plate facing away from the bottom plate, the output shaft of the above-mentioned cylinder is fixedly connected to a V-shaped supporting seat, and rolling elements are respectively installed at both ends of the top of the above-mentioned V-shaped supporting seat, and there is a gap between the two rolling elements.

[0012] Furthermore, the rolling element is a second bearing.

[0013] Furthermore, the linear drive mechanism includes a fixed plate fixedly connected to the base plate, a motor and a mounting seat are provided on a side of the fixed plate facing away from the base plate, a screw rod is provided between the motor and the mounting seat, guide rails are provided on both sides of the screw rod, and one end of the screw rod is connected to the motor, and the other end is connected to the mounting seat, a slider is provided on the screw rod, the slider is fixedly connected to the movable block, and a sliding groove for mounting on the guide rail is recessed on a side of the movable block facing the fixed plate.

[0014] Furthermore, there is a distance between the first vertical plate and the second vertical plate located on the same side.

[0015] Furthermore, a protrusion is provided at the rear end of the top surface of the second vertical plate.

[0016] Furthermore, the height of the first vertical plate is higher than that of the second vertical plate.

[0017] From the above description of the structure of the utility model, it can be seen that the utility model has the following advantages:

[0018] Firstly, the utility model provides a linear transmission mechanism and a supporting rolling assembly that can be translated back and forth under the drive of the linear transmission mechanism on both sides of the bottom plate, so that the leather unwinding roller can be moved from the rolling assembly of the first vertical plate to the rolling assembly of the second vertical plate while maintaining the unwinding state, so that the leather can be unwound continuously, avoiding the situation where the leather is in an over-tensioned state due to the inability of the leather unwinding roller to unwind when moving, and then causing the leather fatigue to damage the appearance quality or breakage, thereby ensuring the appearance quality of the finished leather. In addition, since the linear transmission mechanism and the supporting rolling assembly are used to move the leather unwinding roller, the efficiency is improved compared with manual labor.

[0019] Secondly, the utility model has a spacing between the first vertical plate and the second vertical plate on the same side, so that after the leather unwinding roller is unwinding, the roller can be easily moved out from between the first vertical plate and the second vertical plate to avoid affecting the movement of the leather.

[0020] Thirdly, a raised portion is provided at the rear end of the top surface of the second vertical plate of the utility model, which can limit the movement of the leather unwinding roller, thereby avoiding the situation where the leather unwinding roller is light in weight when the unwinding is about to be completed and is easily displaced by the traction force generated by other production equipment.

DETAILED DESCRIPTION

[0025] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Reference Figures 1 to 3A leather dyeing feeding system comprises a bottom plate 10, with the length direction of the bottom plate 10 as the left-right direction, and first vertical plates 20 perpendicular to the bottom plate 10 are respectively arranged on the left and right sides of the front of the top surface of the bottom plate 10, and second vertical plates 30 perpendicular to the bottom plate are respectively arranged on the left and right sides of the rear of the top surface of the bottom plate 10, and the top surfaces of the first vertical plate 20 and the second vertical plate 30 are both concavely provided with accommodating grooves 40, and the accommodating grooves 40 are approximately located in the middle of the top surfaces of the first vertical plate 20 and the second vertical plate 30, and each accommodating groove 40 is provided with a rolling component for supporting a leather unwinding roller 101. In this embodiment, the rolling component is two first bearings 41 arranged at intervals and rotatable in the front-to-back direction, and linear drive mechanisms arranged horizontally in the front-to-back direction are respectively provided on the left and right sides of the bottom plate 10, and the two linear drive mechanisms are respectively arranged horizontally in the front-to-back direction. The driving mechanism is respectively installed with supporting rolling components that can synchronously translate and move the leather unwinding roller 101 placed on the rolling component of the first vertical plate 20 to the rolling component of the second vertical plate 30. The supporting rolling component includes a movable block 51 installed on the linear driving mechanism, and a mounting plate 511 is erected on the top surface of the movable block 51. A vertically arranged cylinder 52 is fixedly installed on the side of the mounting plate 511 facing away from the base plate 10, and the output shaft of the cylinder 52 is fixedly connected to a V-shaped support seat 53. Rolling elements are respectively installed at both ends of the top of the V-shaped support seat 53. In the present embodiment, the rolling element is a second bearing 54. There is a gap between the two second bearings 54, and a guide shaft 55 is passed through each second bearing 54. The two ends of the guide shaft 55 are respectively connected to the V-shaped support seat 53.

[0027] In this way, when it is used, when the leather unwinding roller 101 located on the first vertical plate 20 is about to complete unwinding, under the drive of the linear drive mechanism, the supporting rolling components on both sides of the bottom plate 10 move to the bottom of the two ends of the leather unwinding roller 101, and then the cylinder 52 lifts and drives the V-shaped support seat 53 to move upward and abut against the two ends of the leather unwinding roller 101, so that the two ends of the leather unwinding roller 101 are placed in the gap between the two rolling elements. Under the action of the rolling elements, the leather unwinding roller 101 can maintain the unwinding state, and then the linear drive mechanism drives the supporting rolling component to move toward the second vertical plate 30. When the supporting rolling component moves to the position corresponding to the rolling component of the second vertical plate 30, the cylinder 52 retracts so that the leather unwinding roller 101 abuts against the rolling component of the second vertical plate 30, thereby realizing continuous unwinding, avoiding the leather being in an over-tensioned state due to the inability to maintain the unwinding state when replacing the leather unwinding roller 101, and then causing leather fatigue damage affecting the appearance quality or leather breakage.

[0028] Reference Figures 1 to 3The linear drive mechanism includes a fixed plate 61 fixedly connected to the base plate 10, and a motor 62 and a mounting seat 63 are provided on the side of the fixed plate 61 facing away from the base plate 10, a screw rod 64 is provided between the motor 62 and the mounting seat 63, guide rails 65 are provided on both sides of the screw rod 64, and one end of the screw rod 64 is connected to the motor 62 through a coupling (not shown in the figure), and the other end is connected to the mounting seat 63, a slider 641 is provided on the screw rod 64, and the slider 641 is fixedly connected to the above-mentioned movable block 51, and a groove (not shown in the figure) for mounting on the guide rail 65 is recessed on the side of the movable block 51 facing the fixed plate 61, so that when used, starting the motor 62 can drive the supporting rolling assembly to translate back and forth on the screw rod 64.

[0029] Reference Figures 1 to 3 There is a distance between the first vertical plate 20 and the second vertical plate 30 located on the same side, so that after the leather unwinding roller 101 has finished unwinding, the roller shaft can be easily moved out from between the first vertical plate 20 and the second vertical plate 30 to avoid affecting the movement of the leather; in order to avoid the situation that the leather unwinding roller 101 is light in weight when it is about to be unwound and is easily displaced by the traction force generated by other production equipment, a protrusion 31 is provided at the rear end of the top surface of the second vertical plate 30, and the protrusion 31 can play a role in limiting the movement of the leather unwinding roller 101; in this embodiment, the height of the first vertical plate 20 is higher than that of the second vertical plate 30. Through such a setting, when it is necessary to sew the leather on the two leather unwinding rollers 101, it is more convenient for workers to operate.

[0030] The utility model arranges linear transmission mechanisms and supporting rolling assemblies that can be translated back and forth under the drive of the linear transmission mechanisms on both sides of the bottom plate 10, so that the leather unwinding roller 101 can be moved from the rolling assembly of the first vertical plate 20 to the rolling assembly of the second vertical plate 30 while maintaining the unwinding state, so that the leather can be unwound continuously, avoiding the situation where the leather is in an over-tensioned state due to the inability of the leather unwinding roller 101 to unwind when moving, and then causing the leather fatigue to damage the appearance quality or breakage, thereby ensuring the appearance quality of the finished leather. In addition, since the linear transmission mechanism and the supporting rolling assembly are used to move the leather unwinding roller 101, the efficiency is improved compared with manual labor.

[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
