Description
Technical Field
[0001] The invention relates to the technical field of strip material winding, in particular to a high-flexibility leather winding device for sofa processing. Background Art
[0002] High-flexibility leather rolling equipment is a kind of equipment specially designed for processing highly flexible, easy-to-bend and deform leather materials (such as synthetic leather, leather, etc.) into rolls. Its main function is to roll the leather materials into rolls in a uniform and wrinkle-free manner during the processing process for easy storage and transportation while maintaining the quality and performance of the material. In the processing of sofas, high-flexibility leather is usually used to cover the surface or corners of the sofa to achieve better wrapping, and the leather in strip form is convenient for sewing, splicing or other processing operations on the sofa, which is suitable for various design and application requirements.
[0003] During the process of winding the leather, the leather will pass through fixed rollers, conveying rollers and winding rollers after processing to achieve transmission. In order to maintain the stability of transportation, squeezing rollers or fixed rollers will be added to the conveying rollers. During the winding process, the leather on the winding roller is increasing. At this time, the diameter of the leather on the winding roller is increasing, so the angle of the leather transferred from the conveying roller to the winding roller is also changing. However, due to the initial positions of the conveying roller and the squeezing roller, the angle of the leather coming out of the conveying roller cannot change; as the entry point of the leather at the winding roller rises, the direction of the section between the leather and the winding roller also changes;
[0004] Since the conveying roller still transports the leather along the original cross section, as the diameter of the leather roll gradually increases, the cross section between the leather and the conveying roller gradually changes. At this time, the leather between the conveying roller and the winding roller cannot be smoothly transported, and a bend will be formed near the conveying roller, which will lead to uneven winding of the leather, causing problems such as uneven surface or uneven tension of the leather, affecting the conveying and winding of the leather.
[0005] There are many solutions to the above problems in the prior art, most of which use a cylinder to adjust the position of the squeezing roller at the conveying roller, thereby changing the cross-section of the leather at the conveying roller. However, after the winding process, as the diameter of the leather roll increases, the angle of the leather entering the leather roll changes all the time. At this time, it is necessary to continuously adjust the squeezing roller as the leather roll is wound, thereby ensuring that the cross-section of the leather at the conveying roller is always maintained. However, the squeezing roller driven by the cylinder is difficult to adjust in real time during the winding process, and thus it is difficult to ensure the quality of the leather winding.
[0006] Based on this, in order to solve the problem that during the winding process, as the diameter of the leather on the winding roller increases, the leather between the conveying roller and the winding roller cannot be transmitted along the cross-section of the conveying roller and the winding roller, thereby affecting the quality of the leather winding, the present invention designs a high-flexibility leather winding equipment for sofa processing. Summary of the invention

The push rod maintains the transmission of the strip leather along the section between the guide plate and the conveying roller through the adjustment mechanism, and then the angle of the strip leather transmitted from the conveying roller will change due to the change of the section, thereby improving the adaptability of winding, and improving the quality and efficiency of winding.

[0012] Preferably, a card plate is installed in the middle of the guide plate, and when the connecting rod rotates to the uppermost position around the center of the conveying roller, the movable end of the card plate squeezes the strip of leather, which can initially limit the thickness of the strip of leather and enable the uniformity of the thickness to be detected before it enters between the conveying roller and the guide plate.
[0013] Preferably, a pulley is installed at the center of the cardboard to prevent the cardboard from being squeezed so that the belt-shaped leather cannot be transmitted.
[0014] Preferably, a rubber ring is installed on the push rod, and a twill block is installed on the rubber ring to reduce the friction resistance of winding.
[0015] Preferably, the diagonal block is arrow-shaped, and the tip of the arrow of the diagonal block is away from the rotation direction of the winding roller, so as to avoid rolling on both sides during winding and improve the winding quality.
[0016] The beneficial effects of the present invention are as follows:
[0017] 1. The high-flexibility leather winding device for sofa processing of the present invention can improve the conveying efficiency of the strip leather by setting a guide plate; and can cooperate with the conveying roller to limit the thickness of the strip leather winding, thereby improving the winding quality; at the same time, the guide plate can change the angle of the strip leather when it is transmitted from the conveying roller, so that the strip leather between the conveying roller and the winding roller is always transmitted along the cross section; at the same time, with the assistance of the stop rod and the adjustment mechanism, it can limit the transmission position of the strip leather and adjust the tension of the strip leather transmission; it can also use itself to block excess foreign matter on the surface, and at the same time, it can prevent the strip leather from rolling up in the transverse section, thereby affecting the winding quality.
[0018] 2. The high-flexibility leather winding device for sofa processing of the present invention, during the transmission process of the conveying roller, is restricted by the guide plate, and the strip leather will always be transmitted from between the conveying roller and the guide plate with a set thickness, thereby improving the uniformity of conveying and winding of the strip leather; at the same time, the clamping of the strip leather between the guide plate and the conveying roller can improve the contact and extrusion of the strip leather and the conveying roller, thereby improving the conveying efficiency of the conveying roller for the strip leather, and avoiding the conveying roller and the strip leather The leather cannot be transmitted to the winding roller for winding due to the lack of contact between the conveying roller and the strip leather. The rotating ring, the rotating rod, the fixed ring, the connecting rod, the guide plate and the driving rod are all in a fixed state, and can synchronously change their positions when the position of the abutting rod changes, and can adaptively adjust the transmission state of the strip leather through the winding state, thereby maintaining the strip leather Can be smoothly wound along the cross-section of the conveying roller and the winding roller, thereby improving the winding efficiency and quality.
[0019] 3. The high-flexibility leather winding device for sofa processing of the present invention has a card plate that can scrape and smooth the surface of the strip leather, which, on the one hand, realizes the removal of surface debris and improves the quality of winding, and on the other hand, can make a preliminary limit on the thickness of the strip leather, so that the uniformity of the thickness can be detected before it enters between the conveying roller and the guide plate. If the thickness difference is too large, the card plate will cause the strip leather to undergo a certain deformation, which will increase the tension, thereby stretching the thick strip leather.

DETAILED DESCRIPTION
[0029] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] like Figure 1 As shown, the present invention provides a high-flexibility leather winding device for sofa processing, comprising a frame 1, a motor 2, a fixed roller 3, a conveying roller 4, a winding roller 5, a mounting groove 6, a connecting rod 7, a guide plate 8, an adjustment mechanism 9 and a stop rod 10. The motor 2 is installed on one side of the frame 1, and the fixed roller 3 is located above the frame 1. In fact, a plurality of fixed rollers 3 can be provided, which play a role in supporting a strip of leather 11 and can transfer the processed strip of leather 11 to the conveying roller 4, so its specific position can be determined according to actual transmission requirements and processing requirements.
[0031] The conveying roller 4 is located in the middle of the frame 1 and is connected to the output end of the motor 2. The conveying roller 4 rotates under the action of the motor 2. Figure 1 When it is in the positive direction, looking from left to right, the conveying roller 4 rotates clockwise under the drive of the motor 2, and the winding roller 5 is installed under the frame 1. The rotation of the conveying roller 4 drives the belt-shaped surface leather 11 to rotate clockwise on the winding roller 5.
[0032] The mounting groove 6 is provided on the frame 1 and is located at the conveying roller 4. The mounting groove 6 is arc-shaped. The connecting rod 7 is installed in the mounting groove 6. The guide plate 8 is installed on the connecting rod 7. The mounting groove 6 is located at the conveying roller 4. Naturally, the connecting rod 7 and the guide plate 8 installed therewith are also located at the conveying roller 4. During the rotation and transmission of the conveying roller 4, the distance between the guide plate 8 and the conveying roller 4 has been limited. The distance between the cross section of the guide plate 8 and the cross section of the conveying roller 4 is set to a fixed value. The fixed value is the standard thickness of the required transmission belt leather 11. Therefore, during the transmission of the conveying roller 4, the belt leather 11 is restricted by the guide plate 8. The belt leather 11 will always be transmitted from between the conveying roller 4 and the guide plate 8 with the set thickness, thereby improving the uniformity of the conveying and winding of the belt leather 11. At the same time, the clamping of the belt leather 11 between the guide plate 8 and the conveying roller 4 can improve the contact and extrusion of the belt leather 11 and the conveying roller 4, thereby improving the conveying of the belt leather 11 by the conveying roller 4. The belt-shaped leather 11 is not in contact with the conveying roller 4, so the belt-shaped leather 11 cannot be transmitted to the winding roller 5 for winding. The arc of the installation groove 6 is concentric with the center of the axis of the conveying roller 4, and the movement trajectory of the connecting rod 7 is also to rotate around the center of the axis of the conveying roller 4, thereby driving the guide plate 8 to have the same movement trajectory. At this time, the guide plate 8 is tangent to the conveying roller 4 through the belt-shaped leather 11 (that is, the distance between the centers of the two is the radius of the two plus the thickness of the belt-shaped leather 11). Therefore, during the rotation of the guide plate 8 around the installation groove 6 through the connecting rod 7, the distance between the center of the guide plate 8 and the center of the conveying roller 4 remains unchanged. Therefore, the rotation of the guide plate 8 will not affect the normal conveying of the conveying roller 4. However, after the guide plate 8 rotates, the position of the line connecting the guide plate 8 and the center of the conveying roller 4 changes, and then the angle of the belt-shaped leather 11 transmitted from the conveying roller 4 will change due to the change of the cross section, thereby improving the adaptability of winding, and improving the quality and efficiency of winding.
[0033] The adjusting mechanism 9 is installed on the guide plate 8, and the push rod 10 is installed above the winding roller 5. The fixed roller 3, the conveying roller 4, the guide plate 8 and the winding roller 5 are sequentially wound with a strip of leather 11 in a serpentine shape. The conveying roller 4 drives the strip of leather 11 to be transmitted under the drive of the motor 2. The guide plate 8 presses the strip of leather 11 to enter the winding roller 5. The push rod 10 moves upward under the pressure of the strip of leather 11 on the winding roller 5, and the push rod 10 maintains the transmission of the strip of leather 11 along the cross section between the guide plate 8 and the conveying roller 4 through the adjusting mechanism 9; the push rod 10 will change its position under the influence of the strip of leather 11 on the winding roller 5. As the diameter of the strip of leather 11 gradually increases after winding, the push rod The height of 10 gradually rises, and then the position of the guide plate 8 and the connecting rod 7 is driven to change through the adjusting mechanism 9. Due to the rotation around the center of the conveying roller 4, the lateral position of the push rod 10 will also change. Therefore, the initial contact position of the push rod 10 with the wound belt-shaped leather 11 is in front of the circle where the wound belt-shaped leather 11 is located (the position of the winding roller 5 relative to the conveying roller 4 is the front, and the conveying roller 4 is the back). Then, when the push rod 10 rotates around the center of the conveying roller 4 under the synchronous action of the adjusting mechanism 9, it can move from the front part of the wound belt-shaped leather 11 to the middle part and finally to the back part. In this process, it is always in contact with the belt-shaped leather 11 and will not be separated.
[0034] As the diameter of the strip leather 11 on the winding roller 5 gradually increases, the angle between the strip leather 11 transmitted between the conveying roller 4 and the winding roller 5 and the horizontal plane gradually decreases. At this time, if the angle at which the conveying roller 4 sends out the strip leather 11 is not adjusted, the strip leather 11 will not be transmitted in a cross-section due to the squeezing of the guide plate 8, thereby affecting the quality of the winding; the guide plate 8 provided here is equivalent to the squeezing roller in the prior art, and has multiple functions. First, it can improve the conveying efficiency of the strip leather 11; second, it can limit the thickness of the winding of the strip leather 11 and improve the winding quality; third, it can limit the transmission position of the strip leather 11, so that the angle of the strip leather 11 when it is transmitted from the conveying roller 4 changes, so that the strip leather 11 between the conveying roller 4 and the winding roller 5 is always transmitted along the cross-section; fourth, it can block excess foreign matter on the surface, and at the same time prevent the strip leather 11 from rolling up in the transverse section, thereby affecting the quality of the winding, etc., so the guide plate 8 is indispensable here.
[0035] like Figure 2As shown, the guide plate 8 is arc-shaped. On the one hand, it can change position synchronously after rotating under the action of the adjusting mechanism 9, and still maintain the cross-section with the belt-shaped leather 11 after the position change, thereby not affecting the transmission of the belt-shaped leather 11; on the other hand, it reduces the overall mass of the guide plate 8 to avoid the guide plate 8 being too heavy to change position (i.e., rotating around the center of the conveying roller 4) under the action of the support rod 10. A contact portion 81 is provided on the guide plate 8. The contact portion 81 is tangent to the conveying roller 4 with respect to the belt-shaped leather 11. The contact portion 81 is in contact with the belt-shaped leather 11. During the rotation of the guide plate 8, the contact portion 81 is always in contact with the belt-shaped leather 11, thereby being able to keep the belt-shaped leather 11 always transmitted outward along the cross-section direction of the guide plate 8 and the conveying roller 4, thereby improving the flatness of the belt-shaped leather 11 before winding, thereby improving the winding quality.
[0036] like Figure 4 , 6 As shown in , 7, the adjustment mechanism 9 includes a swivel 91, a swivel rod 92, a fixed ring 93, a return spring 94 and a driving rod 95. The swivel 91 is installed at the end of the conveying roller 4, and the swivel 91 is rotatably connected to the conveying roller 4. The swivel rod 92 is installed on the swivel 91, the fixed ring 93 is installed on the connecting rod 7, the swivel rod 92 is connected to the fixed ring 93, the return spring 94 is installed in the installation groove 6, one end of the return spring 94 is connected to the connecting rod 7, and the other end of the return spring 94 is connected to the inner wall of the installation groove 6. The driving rod 95 is installed on the connecting rod 7, and the other end of the driving rod 95 is connected to the push rod 10;
[0037] The swivel 91 is connected to the conveying roller 4 for relative rotation, and the swivel 91 will not rotate when the conveying roller 4 rotates with the output shaft of the motor 2. The swivel 91 is also connected to the frame 1 for rotation. When the swivel 91 rotates with the stop rod 10, it can rotate relative to the frame 1. Therefore, a bearing can be provided in the swivel 91 to achieve good drive. The rotating rod 92 is fixedly installed with the swivel 91, and it can be installed in the swivel 91 by plugging. The fixing ring 93 is installed at the end of the connecting rod 7. The connecting rod 7 is fixedly connected to the guide plate 8. Then the fixing ring 93 can synchronously drive the guide plate 8 to move. The fixing ring 93 is connected to the other end of the swivel 92 Then, the driving rod 95 is installed on the connecting rod 7 and is connected to the push rod 10, so that the rotating ring 91, the rotating rod 92, the fixed ring 93, the connecting rod 7, the guide plate 8 and the driving rod 95 are all in a fixed state, and can synchronously change position when the push rod 10 changes position, and then can adaptively adjust the transmission state of the belt leather 11 according to the winding state, so as to keep the belt leather 11 able to be wound smoothly, thereby improving the winding efficiency. The reset spring 94 is installed between the connecting rod 7 and the frame 1 and is located in the mounting groove 6. The reset spring 94 can make the connecting rod 7 always at the lowest end in the absence of external force, thereby ensuring recycling.
[0038] like Figure 5 As shown, a card plate 12 is installed in the middle of the guide plate 8. When the connecting rod 7 rotates around the center of the conveying roller 4 to the uppermost position, the movable end of the card plate 12 squeezes the strip-shaped surface leather 11. In the initial state, the card plate 12 can scrape and smooth the surface of the strip-shaped surface leather 11. On the one hand, it can remove surface debris and improve the quality of winding. On the other hand, it can make a preliminary restriction on the thickness of the strip-shaped surface leather 11 so that the uniformity of the thickness can be detected before entering between the conveying roller 4 and the guide plate 8. If the thickness difference is too large, the card plate 12 will cause a certain deformation of the strip-shaped surface leather 11, which will increase the tension, thereby causing the thick strip-shaped surface leather 11 to be stretched during the conveying. Under the extrusion and transmission of the conveying roller 4 and the guide plate 8, a strip of leather 11 with a thickness that meets the requirements can be formed, thereby improving the winding quality; when the connecting rod 7 rotates around the conveying roller 4 to the other end of the mounting groove 6, the return spring 94 is squeezed and compressed, and the clamping plate 12 will squeeze the strip of leather 11 downward, and the angle of the strip of leather 11 when entering the conveying roller changes, so that in the process of gradually adjusting the cross-section of the strip of leather 11 output from the front end of the conveying roller 4, the strip of leather 11 at the rear end can be synchronously adjusted to a suitable transmission angle under the action of the clamping plate 12, so that the strip of leather 11 can be smoothly transmitted along the cross-section of the conveying roller 4 to the winding roller 5, thereby improving the winding quality.
[0039] A pulley 13 is installed at the center of the cardboard 12. The pulley 13 is used to improve the smoothness of the transmission of the belt-shaped leather 11, to avoid the cardboard 12 being squeezed so that the belt-shaped leather 11 cannot be transmitted, thereby affecting the winding efficiency; at the same time, the pulley 13 here can adhere to impurities, thereby improving the cleanliness of the surface of the belt-shaped leather 11.
[0040] like Figure 3 As shown, a rubber ring 14 is installed on the push rod 10, and rolling can be achieved through the rubber ring 14, thereby ensuring normal winding of the strip leather 11 at the winding roller 5, and the rubber ring 14 can play a squeezing role to avoid the rear corner from curling up during the winding process, which affects the winding quality; a twill block 141 is installed on the rubber ring 14; the twill block 141 is arrow-shaped, and the tip of the arrow of the twill block 141 is away from the rotation direction of the winding roller 5. The arrow-shaped twill block 141 can be opposite to the winding direction, and then in the winding process, the tip of the arrow of the twill block 141 contacts the front end of the strip leather 11, and then gradually extends backwards, thereby ensuring that the two lateral sides of the strip leather 11 will not roll over, and no thickness difference will occur, thereby improving the winding quality.
[0041] During the operation, on the one hand, the terminal end of the film is always tightened by the gravity of the push rod 10. On the other hand, as the push rod 10 gradually rises, it drives the driving rod 95 to flip, gradually changing the section angle between the film input and the output to the winding roller 5, thereby improving the smoothness of the winding. This is a spontaneous winding process without an additional power source. It can spontaneously tighten the strip of leather 11 at the front end of the winding roller 5 according to the thickness of the strip of leather 11 at the winding roller 5. Obviously, this adaptability is not achievable by the spring in the prior art. The spring will not increase the extrusion pressure on the film during the relaxation process, so the extrusion pressure of the film will gradually decrease during the winding process. The tensioning force of the film of the present application will always tighten the strip of leather 11 under the influence of the push rod 10 and the clamping plate 12. At the same time, changing the winding section angle can also ensure that the length of the winding at the front end of the winding roller 5 does not change. At this time, during the gradual increase in the diameter of the strip of leather 11 at the winding roller 5, relaxation will not be achieved.
[0042] Assume that the distance from the center of the guide plate 8 to the tangent point at the input end is x, the distance from the tangent point at the input end to the bottom end of the push rod 10 is y, and the distance from the center of the guide plate 8 to the bottom end of the push rod 10 is z. x is always the radius of the guide plate 8 and is constant. z is affected by the length of the driving rod 95 and is also a fixed value. It can be seen that y is a fixed value, that is, the distance from the tangent point at the input end to the bottom end of the push rod 10 is always constant. Then, as the diameter of the belt-shaped leather 11 at the winding roller 5 increases, the problem of gradual relaxation due to the increase in the winding diameter is reduced.
[0043] From the overall perspective of the guide plate 8, the drive rod 95 and the push rod 10, in addition to being able to achieve the effect of adjusting the tension relaxation when the film is wound, it can also achieve the effects of blocking excess foreign matter on the surface of the strip leather 11, preventing the strip leather 11 from rolling up in the transverse section, and limiting the distance from the intersection point of the front input end of the winding roller 5 to the bottom end of the push rod 10 to remain unchanged.
[0044] When it is necessary to wind the strip leather 11, the motor 2 is started to wind the strip leather 11 around the fixed roller 3, the conveying roller 4, the guide plate 8 and the winding roller 5 in a serpentine shape in sequence, and then the strip leather 11 moves along the winding direction and is finally wound on the surface of the winding roller 5. As the diameter of the strip leather 11 on the winding roller 5 gradually increases, the upper support rod 10 is driven to rotate around the center of the axis of the conveying roller 4, and the driving rod 95 fixed thereto is driven to rotate synchronously, and then the rotating ring 91, the rotating rod 92, the fixed ring 93, the connecting rod 7 and the guide plate 8 are driven to rotate synchronously, and the connecting rod 7 gradually squeezes the reset spring 94; during the rotation of the guide plate 8, the center distance between the guide plate 8 and the conveying roller 4 remains unchanged, but the center distance of the center The straight line position changes, thereby driving the change in the cross-sectional direction of the strip leather 11 tangent to the two, thereby improving the smoothness of entering the winding roller 5 and improving the winding quality. The rotating guide plate 8 drives the clamping plate 12 to squeeze the strip leather 11 and cause it to deform, thereby changing the angle at which the strip leather 11 enters between the conveying roller 4 and the guide plate 8; after the winding is completed, the strip leather 11 is cut off, the wound strip leather 11 is taken off, and the cut-off strip leather 11 is rewound onto the winding roller 5, and the push rod 10, the driving rod 95, the guide plate 8 and the connecting rod 7 are reset by the reset spring 94 and return to the initial position again, thereby realizing the circular winding.
[0045] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements. These changes and improvements all fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
