Description

Technical Field

[0001] The present invention relates to the technical field of cloth processing equipment, and more specifically, to a cloth pressing and connecting assembly, a cloth pressing production line, and a cloth pressing method. Background Art

[0002] Among the various fabric connection processes, there is a relatively special method, namely, fabric riveting. Fabric riveting is usually used for fabrics such as curtain fabrics, canvas, and linen. Usually, the texture of the fabric is relatively hard and the thickness is relatively large. Through riveting, not only can the fabrics be connected, but also the riveted parts themselves can form riveted style decorations at the connection positions of the fabrics. In the riveting process, the fabrics are first pre-punched, and then the riveted parts are pressed together by a riveting machine or a rotary riveting machine to achieve the connection between the fabrics.

[0003] There are some differences between the press riveting of fabric and other riveting methods. Since the strength of fabric is lower than that of metal materials, the riveting of fabric requires higher quality of riveting and higher quality of forming at the riveted end. In addition, some riveted parts also need decoration, so there are also higher requirements for the forming surface state of the riveted end. During the riveting process, it is usually necessary to adjust the riveting angle. Through different riveting angles, it can adapt to different riveted parts and various riveted forming surface qualities.

[0004] In the current fabric riveting equipment, one method of adjusting the angle of the pressing head is to replace the pressing head, that is, to prepare multiple groups of different pressing heads for different pressing angles in advance, and replace the pressing heads as needed to meet the requirements as much as possible. However, this method has great limitations, and can only roughly distinguish the adjustment angles, and cannot make more precise adjustments to the pressing angles.

[0005] Another type of cloth riveting equipment uses a rotating shaft adjustment method for adjustment. The pressing head is supported by the rotating shaft and fixed by other adjustment structures. During the adjustment process, the tilt adjustment of the pressing angle can be achieved by rotating and swinging the pressing head, and the rotating adjustment method can arbitrarily adjust the pressing angle within a certain range, thereby improving the precision and accuracy of the pressing head sleeve. In this adjustment method, although the angle of the pressing surface at the lower end of the pressing head can be changed after the pressing head rotates and swings, the position of the lower end of the pressing head will also produce lateral movement during the swing adjustment process, resulting in a certain offset between the lower end of the pressing head and the original pressing position, causing the pressing head to be unable to accurately align with the riveted part at the pressing position, which may affect the normal riveting. It is even necessary to perform a horizontal adjustment on the structure of the pressing head and the supporting position of the riveted part at the lower end after the swing adjustment, which is not conducive to the adjustment operation.

[0006] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present embodiment discloses a fabric pressing connection component, which can connect fabrics 50 to each other by riveting and pressing, thereby connecting two layers of fabric 50 to each other, for example, relatively thick fabrics 50 such as curtains can be connected.

[0032] The pressing connection assembly includes a support tube 1, in which an adjustment chamber 2 with an open lower end is arranged. A pressing mechanism is installed in the adjustment chamber 2, and the rivet 60 is pressed by the pressing mechanism to achieve connection between the fabrics 50.

[0033] like Figure 2-5 As shown, the pressing mechanism includes a main connecting rod 3 and a pressing head 31, the pressing head 31 is fixed to the lower end of the main connecting rod 3, and has a downward pressing surface 32 at the lower end of the pressing head 31, through which the pressing surface 32 is pressed against the rivet 60 to achieve mutual pressing and connection between the fabrics 50.

[0034] The main connecting rod 3 can be tilted and adjusted, so that the pressing surface 32 at the lower end of the main connecting rod 3 can also be tilted and adjusted, so as to achieve a riveting pressing state with different pressures. During the adjustment process, the center position of the pressing surface 32 can be kept in a basically inconvenient position, always located directly above the pressing position, so as to ensure that the pressing head 31 can be kept in a state of being directly opposite to the riveting position during the tilt adjustment, avoiding the tilt deviation of the pressing head 31 during the swing adjustment, and ensuring that the pressing head 31 can stably adjust the rivet 60 without adjusting the horizontal position of the press-fit connection assembly.

[0035] like Figure 2 As shown, the pressing mechanism also includes a secondary connecting rod 4, which cooperates with the main connecting rod 3 to swing and adjust the main connecting rod 3 and the pressing head 31 at the lower end. The lower end of the secondary connecting rod 4 is rotatably connected to the middle of the main connecting rod 3 through a linkage shaft 43, and the upper end of the secondary connecting rod 4 is rotatably connected to the inner wall of the support tube 1 through a support shaft 44. The main connecting rod 3 is supported by the secondary connecting rod 4 to achieve linkage adjustment with the main connecting rod 3.

[0036] In order to maintain the connection stability between the main connecting rod 3 and the auxiliary connecting rod 4, the auxiliary connecting rod 4 can be set into two groups, namely the first auxiliary connecting rod 41 and the second auxiliary connecting rod 42. The first auxiliary connecting rod 41 and the second auxiliary connecting rod 42 are parallel to each other and rotatably support the main connecting rod 3 on both sides.

[0037] During the adjustment process, by adjusting the lateral direction of the upper end of the main connecting rod 3, the main connecting rod 3 can be adjusted to tilt and swing, and then the tilt angle of the pressing head 31 can be adjusted. An inverted triangle structure is formed between the upper section of the main connecting rod 3 and the secondary connecting rod 4. By adjusting the upper end of the main connecting rod 3 laterally, the lateral displacement of the tilt and swing of the lower end of the main connecting rod 3 can be compensated, and then the position of the pressing surface 32 of the lower end of the pressing head 31 is kept basically in a stable state in the horizontal direction, ensuring that the pressing head 31 can press the rivet 60 normally, and the angle of the pressing surface 32 can be adjusted.

[0038] like Figure 2 , 3As shown in , 4, in order to maintain the adjustment stability of the pressing mechanism, an adjustment block 5 can be rotatably connected to the upper end of the main connecting rod 3 through an adjustment shaft 52. A screw hole 51 is provided in the adjustment block 5, and a screw rod 6 is threadedly connected to the screw hole 51. The screw rod 6 is in a horizontal state, and the connection block can be adjusted horizontally along the screw rod 6. The two ends of the screw rod 6 pass through the two ends of the support tube 1, and a rotating support sleeve 7 is installed at the corresponding position of the support tube 1. The two ends of the screw rod 6 are rotationally supported by the rotating support sleeve 7, which can keep the screw rod 6 rotating smoothly and maintain axial stability. In order to maintain the stability of the screw rod 6 after adjustment, a radial screw can be installed between the end of the screw rod 6 and the rotating support sleeve 7. The screw is radially screwed in from the outer periphery of the rotating support sleeve 7. The end of the screw can be pressed against the outer periphery of the screw rod 6, and can be locked by friction. The screw can be loosened in advance during adjustment, thereby maintaining the stability of the screw rod 6 after the position is adjusted.

[0039] The adjusting block 5 is threadedly matched with the screw rod 6. During the rotation and adjustment process of the screw rod 6, thread linkage can be generated between the threads, and the axial rotation action is converted into the axial movement of the adjusting block 5, so as to realize the lateral adjustment of the adjusting block 5. Through the lateral adjustment of the adjusting block 5, the main connecting rod 3 can be tilted and adjusted, so as to realize the tilting and swinging of the pressing head 31.

[0040] Furthermore, the axis of the linkage shaft 43, the axis of the adjustment shaft 52 and the center of the pressure surface 32 are coplanar; and, the axis spacing between the linkage shaft 43 and the adjustment shaft 52 is a1, the axis spacing between the linkage shaft 43 and the center of the pressure surface 32 is a2, and the axis spacing between the linkage shaft 43 and the support shaft 44 is a3, and the lengths of a1, a2, and a3 are kept equal.

[0041] like Figure 7 As shown, an isosceles triangle structure is formed between the support shaft 44, the linkage shaft 43 and the adjustment shaft 52, and an isosceles triangle structure is also formed between the support shaft 44, the linkage shaft 43 and the center position of the pressing surface 32. The support shaft 44 is located in an inconvenient position, and during the lateral adjustment of the adjustment block 5 along the screw 6, the center position of the pressing surface 32 at the lower end of the pressing head 31 can be kept in an inconvenient position, so that the rivet 60 can be stably pressed.

[0042] The pressure head 31 and the lower end of the main connecting rod 3 can be provided with a detachable structure, and can be specifically installed and fixed by bolts, so as to facilitate the disassembly and replacement of the pressure head 31 and the maintenance of the pressure head 31.

[0043] The fabric pressing and connecting assembly also has a rotary driver 20 and a lifting driver. The lifting driver can be a pneumatic cylinder. The rotary driver 20 is installed at the lifting end of the lifting driver and is adjusted by the lifting driver. The support tube 1 is installed at the rotating end 21 of the rotary driver 20 and can be rotated. The pressing head 31 at the lower end of the pressing mechanism extends outward, thereby realizing the pressing processing of the riveted part 60. The rotary driver 20 can drive the pressing head 31 to rotate, and the riveted part 60 is subjected to the rotary riveting processing, so that the riveted part 60 is stably riveted, and the fabrics 50 can be stably connected.

[0044] The axis of the rotating end 21 is vertical and passes through the center of the pressing surface 32 of the pressing head 31 . During the tilt adjustment process of the pressing head 31 , the center of the pressing surface 32 is always located in the axial direction of the rotating end 21 .

[0045] Since the pressing head 31 is in an adjustable tilt state, the tilt angle of the pressing head 31 can be adjusted according to the riveting requirements of the rivet 60, and then adjusted to an appropriate riveting state, so that stable rotary riveting of the rivet 60 can be achieved and the end of the rivet 60 can be maintained smooth and stable.

[0046] This embodiment also discloses a cloth pressing production line, such as Figure 6 As shown, it includes the cloth pressing and connecting assembly in the above embodiment, and the cloth pressing and connecting assembly can press and connect two layers of cloth 50 by means of rivet pressing.

[0047] The fabric pressing production line also includes two sets of belt assemblies 30, which are connected in sequence to convey the fabric 50. Each set of belt assemblies 30 is located in the upper and lower belts and driven by pulleys respectively. The fabric 50 is pressed by the belts on the upper and lower sides, which can smoothly drive the fabric 50 and keep the fabric 50 flat and stable for conveying.

[0048] The two groups of belts are arranged along the conveying direction of the cloth 50 , and a gap is formed between the two groups of belt supports. A support platform 40 is installed at the position of the gap space, and the support platform 40 is located at the lower side of the cloth 50 .

[0049] A pressing seat 401 is installed on the upper part of the support platform 40, and the fabric pressing and connecting assembly is located above the pressing seat 401. The support tube 1 and the pressing head 31 can be raised and lowered. During the pressing process, the pressing head 31 can press the rivet 60 between the two layers of fabric 50, thereby achieving riveting of the rivet 60, and the pressing seat 401 supports the lower end of the rivet 60.

[0050] The pressing head 31 in the fabric pressing connection assembly can be tilted and adjusted, and the center of the pressing surface 32 at the lower end of the pressing head 31 is always located directly above the pressing seat 401, so as to realize pressing and riveting of rivets with different requirements.

[0051] The position of the pressing seat 401 is also connected to a rivet 60 feeding assembly, which can be transported through a vibration plate in conjunction with a conveying track, and can transport the rivet 60 to be used to the pressing seat 401, thereby realizing normal feeding of the rivet 60, and facilitating the riveting process. In addition, a through hole 70 can be formed in advance at the position corresponding to the installation of the rivet 60 on the cloth 50, thereby facilitating the rivet 60 to pass through the cloth 50, thereby facilitating the installation of the rivet 60, and facilitating the mutual pressing and connection of the two layers of cloth 50. Specifically, the feeding assembly and the cloth punching equipment can adopt the existing equipment structure, which belongs to the prior art and is not an improvement point of this solution, and will not be described in detail here.

[0052] The present embodiment also discloses a method for pressing cloth, which is processed by the above-mentioned cloth pressing production line. First, two layers of cloth 50, namely cloth 1 501 and cloth 2 502, are overlapped with each other and conveyed by the belt assembly 30. The two overlapping layers of cloth 50 pass above the pressing seat 401. The cloth pressing and connecting assembly is used to rivet and press the cloth 50, forming a strip-shaped pressing path on the cloth 50, forming a strip-shaped rivet member 60 distribution state, and realizing a stable pressing connection between the two layers of cloth 50, such as Figure 8 Status shown.

[0053] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
