Description

Technical Field

[0001] This utility model relates to the field of sewing machines, and more particularly to a sewing conveying device. Background Technology

[0002] In the automated sewing process of textiles, a conveying device is often used to transport the fabric to be sewn to the presser feet of the sewing machine.

[0003] In the prior art, to obtain greater driving force, one improvement is to design the first conveying mechanism as a symmetrical clamping structure, with one located above the worktable and the other below, conveying the fabric by clamping it from above and below. However, this structure has obvious drawbacks.

[0004] The mechanical structure of the first conveyor mechanism located below the worktable interferes with the sewing machine base, preventing it from extending into the sewing area. As a result, the front end of the fabric loses its grip and drive from the drive mechanism after entering the presser foot. This causes an imbalance in the driving force on the front and rear ends of the fabric during the critical initial sewing stage, easily leading to fabric skewing, curling, or wrinkling, affecting sewing quality and product yield. Utility Model Content

[0005] The purpose of this invention is to provide a sewing conveying device to solve the problem of unbalanced driving forces on both sides of the fabric during sewing in the prior art.

[0006] The technical solution of this utility model is: a sewing conveying device, including a worktable, a sewing machine and a first conveying mechanism are arranged on one side of the worktable, and a second conveying mechanism is arranged on the other side; the two sides of the workpiece being sewn are driven towards the sewing machine by the first conveying mechanism and the second conveying mechanism respectively; The first conveying mechanism is symmetrically arranged relative to the upper surface of the worktable, and one of the first conveying mechanisms is connected to a lifting mechanism, so that a pair of first conveying mechanisms can clamp the sewn work and move it toward the sewing machine. One of the first conveying mechanisms is connected to a material-setting mechanism, which is located between the second conveying mechanism and the sewing machine. The material-setting mechanism is able to abut against the upper surface of the workpiece being sewn.

[0007] Preferably, the first conveying mechanism is connected to the material sizing mechanism via a connecting rod, and the connecting rod is connected to a conveying drive mechanism, which drives the connecting rod to rotate so that the first conveying mechanism and the material sizing mechanism run in the same direction; A lifting mechanism is provided, which is connected to the material preparation mechanism and the first conveying mechanism connected to the material preparation mechanism via a conveying base.

[0008] Preferably, the conveying base includes a mounting plate arranged parallel to the worktable. The mounting plate is arranged in a zigzag structure corresponding to the first conveying mechanism and the material balancing mechanism. A top mounting frame and a bottom mounting frame are vertically fixed on the mounting plate. The conveying drive mechanism is arranged on the top mounting frame, and the first conveying mechanism and the material balancing mechanism are arranged on the bottom mounting frame.

[0009] Preferably, the first conveying mechanism and the material balancing mechanism each include a conveying wheel and a material balancing pressure roller, and at least two of each are provided. A conveyor belt and a material balancing pressure belt are respectively fitted on the two conveying wheels and the two material balancing pressure rollers; the two ends of the connecting rod are respectively coaxially fixed to one conveying wheel and one material balancing pressure roller.

[0010] Preferably, the conveying drive mechanism includes a driver, a first drive wheel is coaxially disposed at the actuating end of the driver, a second drive wheel is coaxially disposed at the middle section of the connecting rod, and a drive belt is sleeved on the first drive wheel and the second drive wheel.

[0011] Preferably, the lifting mechanism includes a lifting driver and a guide; the two ends of the lifting driver are respectively connected to the worktable and the mounting plate, and the guide includes a slide rail and a slider respectively fixed to the mounting plate and the worktable.

[0012] Preferably, a tensioning mechanism is included, which is provided corresponding to the first conveying mechanism, the material straightening mechanism and the conveying drive mechanism. The tensioning mechanism includes adjustment holes respectively opened on the top mounting frame and the bottom mounting frame. Each adjustment hole has a length direction facing the conveyor belt or drive belt. A tensioning wheel is fitted in each adjustment hole, and the rim of the tensioning wheel abuts against the corresponding conveyor belt or drive belt.

[0013] Compared with the prior art, the advantages of this utility model are: This application ensures that the fabric receives continuous and uniform driving force throughout the entire sewing path, especially in the critical front area, by installing a material-aligning mechanism above the worktable that does not interfere with the sewing machine. This effectively avoids fabric skewing, curling, or wrinkling caused by uneven driving force, significantly improving the straightness of the stitches and the sewing quality of the product.

[0015] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and Figure 2 As shown, a sewing conveying device includes a worktable 1. A sewing machine 2 and a first conveying mechanism 3 are arranged on one side of the worktable 1, and a second conveying mechanism 4 is arranged on the other side. The two sides of the workpiece being sewn are driven towards the sewing machine 2 by the first conveying mechanism 3 and the second conveying mechanism 4, respectively.

[0016] To achieve greater driving force on the sewn material, combine Figure 3 As shown, the first conveying mechanism 3 is symmetrically arranged relative to the upper surface of the worktable 1. One of the first conveying mechanisms 3 is located above the worktable 1, and the other first conveying mechanism 3 is located below the worktable 1. The sewn material (fabric) is clamped and conveyed by the two first conveying mechanisms 3.

[0017] Because the first conveying mechanism 3, located below the workbench 1, interferes with the sewing machine 2 when it extends to it, the front end of the fabric (the object being sewn) loses its drive during sewing. This causes uneven driving force on the front end of the fabric during sewing, making it prone to skewing or curling.

[0018] To solve this problem, this application connects a material straightening mechanism 5 to the first conveying mechanism 3 located above the workbench 1. The material straightening mechanism 5 is located between the second conveying mechanism 4 and the sewing machine 2. The material straightening mechanism 5 can abut against the upper surface of the fabric, keep the fabric in contact with the workbench 1 and give the fabric a driving force on the side away from the second conveying mechanism 4.

[0019] Combination Figure 4As shown, in this embodiment, the first conveying mechanism 3 is connected to the material-forming mechanism 5 via a connecting rod 6. The connecting rod 6 is connected to a conveying drive mechanism 7, which drives the connecting rod 6 to rotate, causing the first conveying mechanism 3 and the material-forming mechanism 5 to run in the same direction. Furthermore, a lifting mechanism 8 is provided, which is connected to the material-forming mechanism 5 and the first conveying mechanism 3 connected to the material-forming mechanism 5 via a conveying base 9. The lifting mechanism 8 drives the first conveying mechanism 3 and the connected material-forming mechanism 5 to move up and down, allowing the fabric to enter more easily below it.

[0020] Specifically, the conveying base 9 includes a mounting plate 91 arranged parallel to the worktable 1. The mounting plate 91 is arranged in a zigzag structure corresponding to the first conveying mechanism 3 and the material straightening mechanism 5. A top mounting frame 92 and a bottom mounting frame 93 are vertically fixed on the mounting plate 91. The conveying drive mechanism 7 is arranged on the top mounting frame 92, and the first conveying mechanism 3 and the material straightening mechanism 5 are arranged on the bottom mounting frame 93.

[0021] The first conveying mechanism 3 and the material balancing mechanism 5 each include a conveying wheel 31 and a material balancing pressure wheel 51. Multiple conveying wheels 31 and material balancing pressure wheels 51 are provided. Conveyor belts 32 and material balancing pressure belts 52 are respectively fitted onto the conveying wheels 31 and material balancing pressure wheels 51 located at both ends. The two ends of the connecting rod 6 are coaxially fixed to one conveying wheel 31 and one material balancing pressure wheel 51, respectively.

[0022] The conveying drive mechanism 7 includes a driver 71, and a first drive wheel 72 is coaxially mounted on the actuating end of the driver 71. A second drive wheel 73 is coaxially mounted on the middle section of the connecting rod 6, and a drive belt 74 is sleeved on the first drive wheel 72 and the second drive wheel 73.

[0023] The lifting mechanism 8 includes a lifting driver 81 and a guide 82. In this embodiment, the lifting driver 81 is a cylinder, and its two ends are connected to the worktable 1 and the mounting plate 91, respectively. Through its telescopic movement, the mounting plate 91 is raised and lowered. The guide 82 includes a slide rail and a slider that are fixed to the mounting plate 91 and the worktable 1, respectively. During the lifting process, the slider slides along the slide rail.

[0024] In addition, a tensioning mechanism 100 is provided, which is provided in accordance with the first conveying mechanism 3, the material straightening mechanism 5 and the conveying drive mechanism 7. The tensioning mechanism 100 includes adjustment holes respectively opened on the top mounting frame 92 and the bottom mounting frame 93. Each adjustment hole has a length direction facing the conveyor belt 32 or the drive belt 74. A tensioning wheel is provided in each adjustment hole, and the rim of the tensioning wheel abuts against the corresponding conveyor belt 32 or the drive belt 74.

[0025] During work: The lifting mechanism 8 drives the mounting plate 91 to rise, and the operator places the fabric into a pair of first conveying mechanisms 3.

[0026] The conveying drive mechanism 7 is started, driving the first conveying mechanism 3 and the material handling mechanism 5 to operate. At the same time, the second conveying mechanism 4 operates synchronously, feeding the fabric from the far end into the corresponding sewing area of ​​the sewing machine 2, and finally transferring it to the presser feet of the sewing machine 2.

[0027] Once the front end of the fabric enters the presser foot of sewing machine 2, sewing machine 2 begins sewing. During this process, while the fabric is being sewn by sewing machine 2, the fabric straightening mechanism 5 continuously drives the fabric and keeps it in contact with the worktable 1.
