Description

Technical Field

[0001] This utility model relates to the field of Velcro sewing technology, specifically to a four-sided sewing structure of a Velcro sewing device. Background Technology

[0002] Velcro is a common connecting accessory used in clothing, bags, toys and other products. It is fixed by bonding the male and female sides. In order to improve the rigidity of Velcro products and the ease of use, a base layer needs to be sewn on its working side (male or female side).

[0003] Currently, hook and loop fastener sewing is mostly done manually. Workers take raw materials from a basket, align the working surface with the base surface, stack them together, and then sew them together using a sewing device to complete the production of the hook and loop fastener product. With the continuous increase in labor costs, production costs are constantly rising. Furthermore, due to differences in worker skills and proficiency, the consistency of hook and loop fastener products is easily affected. Manual sewing is costly, labor-intensive, inefficient, and results in inconsistent product quality. Therefore, there is a need to design automated hook and loop fastener sewing equipment.

[0004] Some existing automatic Velcro sewing devices require a pressure strip to hold the material in place during sewing, which prevents the stitching from running at the joint of the pressure strip. The stitching can only be done around the pressure strip on three sides, which makes the sewing fixation unreliable. Therefore, its structure needs further improvement. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a four-side sewing structure of a hook and loop fastener sewing device with a reasonable structure, which can realize the sewing of the four sides of hook and loop fastener products, thereby improving the reliability of hook and loop fastener products.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A four-sided sewing structure for a Velcro sewing device includes a frame, a sewing machine mounted on the frame, a movable frame mounted on the frame, a material conveying channel mounted on the movable frame, material conveying grippers mounted beside the material conveying channel, and a sewing pressure strip mechanism and a sewing pressure block mechanism also mounted beside the material conveying channel. The sewing pressure strip mechanism includes a base connected to a lifting device, a horizontal push cylinder mounted on the base, and a long pressure strip connected to the horizontal push cylinder. The sewing pressure block mechanism is located at the end of the material conveying channel and includes a lifting pressure block.

[0008] Further optimization measures for this technical solution are as follows:

[0009] As an improvement, the stitching block mechanism further includes an inclined base, on which a driving cylinder is fixed, and the pressing block is connected to the driving cylinder.

[0010] As an improvement, a connecting block is connected to the drive cylinder, and the pressure block is fixed to the connecting block.

[0011] As an improvement, the connecting block has an L-shaped structure.

[0012] As an improvement, a guide strip is provided on the side of the drive cylinder, and the connecting block slides in cooperation with the guide strip. The cooperation between the guide strip and the connecting block improves the stability and reliability of the connecting block's movement.

[0013] The movement and lifting of the pressure block are controlled by tilting the drive cylinder, resulting in a compact structure that occupies little space.

[0014] As an improvement, the flat-push cylinder is connected to the long pressure bar via a sliding block, and a slide rail is provided on the base, with the sliding block and the slide rail slidingly engaged.

[0015] As an improvement, the material conveying gripper includes a conveying guide rail fixed to the frame, a slider slidably fitted on the conveying guide rail, a first lifting cylinder fixed on the slider, a mounting base connected to the first lifting cylinder, a fixed head and a second lifting cylinder provided on the mounting base, and a movable head that cooperates with the fixed head connected to the second lifting cylinder.

[0016] As an improvement, a connecting plate is connected to the slider, the connecting plate is connected to the conveyor belt, and the conveyor belt is wound around two rotating wheels, one of which is connected to a drive motor.

[0017] The advantages of this utility model compared with the prior art are:

[0018] This utility model discloses a four-sided sewing structure for a Velcro sewing device. The structure is rationally designed, featuring a sewing pressure strip mechanism and a sewing pressure block mechanism installed beside the material conveying channel. The sewing pressure strip mechanism can be raised and lowered as a whole under the control of a lifting device, thereby driving the raising and lowering of the long pressure strip. The sewing pressure block mechanism includes a liftable pressure block. When sewing materials (working surface and base surface), the long pressure strip of the sewing pressure strip mechanism first holds the material down. As the moving frame moves, the sewing machine sews three sides of the material around the long pressure strip. Then, the pressure block of the sewing pressure block mechanism holds down the tail of the material. The sewing pressure strip mechanism then moves, the moving frame moves, and the sewing machine sews the fourth side of the material, thus achieving four-sided sewing of the material and effectively improving the reliability of Velcro products.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings:

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] like Figures 1 to 6 As shown, a four-sided sewing structure of a Velcro sewing device includes a frame 1, a sewing machine 5 mounted on the frame 1, a movable frame 11 mounted on the frame 1, a material conveying channel 12 mounted on the movable frame 11, a material conveying gripper 2 mounted beside the material conveying channel 12, and a sewing pressure strip mechanism 3 and a sewing pressure block mechanism 4 mounted beside the material conveying channel 12. The sewing pressure strip mechanism 3 includes a base 31 connected to a lifting device, a flat-push cylinder 32 mounted on the base 31, and a long pressure strip 33 connected to the flat-push cylinder 32. The sewing pressure block mechanism 4 is located at the tail end of the material conveying channel 12 and includes a lifting pressure block 41.

[0033] The lifting device described above is preferably a cylinder.

[0034] In this embodiment, the stitching pressure block mechanism 4 further includes an inclined base 42, on which a driving cylinder 43 is fixed, and the pressure block 41 is connected to the driving cylinder 43.

[0035] A connecting block 44 is connected to the drive cylinder 43, and the pressure block 41 is fixed to the connecting block 44.

[0036] The connecting block 44 has an L-shaped structure.

[0037] The drive cylinder 43 has a guide strip 43a on its side, and the connecting block 44 slides in cooperation with the guide strip 43a. By having the long side of the L-shaped structure of the connecting block 44 cooperate with the guide strip 43a, the movement of the connecting block 44 can be made more stable, thereby making the movement of the pressure block 41 more stable.

[0038] The stitching pressure block mechanism 4 uses an inclined drive cylinder 43 to drive the lifting and lowering of the pressure block 41. The pressure block 41 moves obliquely, has a compact structure, and occupies little space.

[0039] The flat-push cylinder 32 is connected to the long pressure bar 33 through the slide block 34, and the base 31 is provided with a slide rail 35, and the slide block 34 and the slide rail 35 are in sliding cooperation.

[0040] The function of the material conveying gripper 2 is to convey the working surfaces and base surfaces of the previous processes together into the material conveying channel 12 of the moving frame 11, that is, to convey the materials (working surfaces and base surfaces) to the sewing process for sewing.

[0041] The material conveying gripper 2 includes a conveying guide rail 21 fixed on the frame 1, a slider 22 slidably fitted on the conveying guide rail 21, a first lifting cylinder 23 fixed on the slider 22, a mounting base 24 connected to the first lifting cylinder 23, a fixed head 25 and a second lifting cylinder 26 provided on the mounting base 24, and a movable head 27 that cooperates with the fixed head 25 connected to the second lifting cylinder 26.

[0042] A connecting plate 22a is connected to the slider 22, and the connecting plate 22a is connected to the conveyor belt 22b. The conveyor belt 22b is wound around two rotating wheels 22c, one of which is connected to a drive motor 22d. The drive motor 22d drives the rotating wheel 22c to rotate, thereby driving the conveyor belt 22b to move, which in turn drives the slider 22 to move along the conveyor guide rail 21 via the connecting plate 22a.

[0043] Working principle:

[0044] The material is conveyed by the material conveying gripper 2 to the material conveying channel 12 of the moving frame 11. During this conveying process, after the sewing pressing strip mechanism 3 is raised as a whole, the flat push cylinder 32 moves the long pressing strip 33 out of the material conveying channel 12 to avoid it. At the same time, the pressing block 41 of the sewing pressing block mechanism 4 is in the raised state.

[0045] When the material conveying gripper 2 clamps the material, the movable head 27 is raised and lowered by the second lifting cylinder 26. The clamping function is achieved by the cooperation of the movable head 27 and the fixed head 25. After the gripper clamps the working surface and the base surface, the drive motor 22d is started to drive the slider 22 to move along the conveying guide rail 21 to achieve conveying.

[0046] Then, the seam sealing mechanism 3 operates, and the flat-push cylinder 32 moves the long sealing strip 33 above the material. The entire seam sealing mechanism 3 descends, using the long sealing strip 33 to fix the material in place. The moving frame 11, along with its various mechanisms (seam sealing mechanism 3, seam sealing block mechanism 4), moves under the sewing machine 5, causing the sewing thread to run around the long sealing strip 33, completing the seam of the three sides of the Velcro. The movement of the moving frame 11 is a conventional structure of automatic sewing equipment and is existing technology; its specific structure will not be described in detail here.

[0047] After the three sides are sewn, the sewing pressure block mechanism 4 operates, driving the cylinder 43 to lower the pressure block 41 to press down on the tail end of the Velcro. Then, the sewing strip mechanism 3 operates, causing the long pressure strip 33 to move out of the material conveying channel 12. The moving frame 11 moves again to complete the sewing of the fourth side, forming a closed rectangle with the four-sided sewing line. Since the three sides have already been sewn when the fourth side is sewn, the working surface and the base surface are now fixed together as a whole. Therefore, pressing down only the tail end of the Velcro when sewing the fourth side will not affect the sewing operation. The stitching L of the Velcro sewn using this four-sided sewing structure is as follows: Figure 7 As shown.

[0048] This utility model has a four-sided stitching structure, which can stitch the four sides of the hook and loop fastener, effectively improving the reliability of hook and loop fastener products.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
