Description

Technical Field

[0001] This utility model belongs to the technical field of garment processing equipment, and more specifically, relates to a bag opening component. Background Technology

[0002] In the garment manufacturing process, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The processing of the pocket opening requires cutting, folding, shaping, and sewing the pocket opening area of ​​the garment. Folding involves folding the cut pocket opening inward to form a folded edge, shaping the pocket edge involves placing the pocket edge on the folded edge, and finally sewing.

[0003] Currently, in the folding pocket process after laser cutting, the first step is to extend the fixed material cutter to form a fixed material opening (pocket shape), and then the pull plate extends into the fixed material opening. The bottom plate below the pull plate moves downward, and the insert cutter inserts the fabric into the fixed material opening of the pull plate. Then, the pull plate pulls the fabric to the side, so that the fabric is between the pull plate and the bottom plate, forming a pocket shape. Finally, the fixed material cutter is retracted to complete the folding pocket process. During this process, the end of the bottom plate away from the pull plate is fixedly connected, and the other end of the bottom plate is installed and connected to the drive assembly, which controls its up and down movement.

[0004] As the base plate moves downwards, it tilts relative to the pull plate, causing an inconsistency in the vertical distance between the pull plate and the base plate on both sides. One side has a larger distance, while the other side has a smaller distance. As a result, fabric at the smaller distance cannot be folded properly when bagging, while fabric at the larger distance can be folded properly. Consequently, fabric at the smaller distance is prone to misalignment, wrinkles, or incomplete folding, leading to an increased defect rate. Therefore, increasing the vertical distance between the pull plate and the base plate to improve production yield is crucial. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bag opening component, which can reduce the inclination of the bottom plate relative to the bag opening groove of the bottom plate component, increase the vertical distance between the bottom plate and the pull plate, so that the folding of the fabric can be completed smoothly and the production yield can be improved.

[0006] This utility model provides a bag opening assembly, including a support plate, a bottom plate, and a support component. The bottom plate is installed at the bottom of the support plate, with its front end fixedly connected to the bottom of the support plate and its rear end movably disposed relative to the support plate. The rear end is connected to the output end of an external driver and can move and bend vertically. The support component is rotatably disposed between the support plate and the bottom plate assembly.

[0007] The bottom of the support plate is recessed and has a rolling groove; the rolling groove is shallower at the front end of the support plate and deeper at the rear end, with the groove depth changing linearly to form an inclined step layer; the top of the support component is rolled in the rolling groove and abuts against the inclined step layer, and the bottom of the support component abuts against the top of the base plate, so as to drive the front of the base plate to move vertically and bend.

[0008] As a further improvement of this utility model, the support assembly includes several top rings and top plate tie rods; the top plate tie rods are mounted above the base plate; the top rings are respectively rotatably sleeved on the top plate tie rods above the base plate and abut against the top of the base plate.

[0009] The top of the top ring is rolled in the corresponding rolling groove and abuts against the inclined step layer. The bottom of the top ring abuts against the top of the base plate. The top ring is fixed near the base plate and the support plate.

[0010] The top plate pull rod is connected to the output of the peripheral driver so that it can reciprocate along the opening direction of the rolling groove.

[0011] As a further improvement of this utility model, the number of rolling grooves is the same as that of the top ring.

[0012] As a further improvement of this utility model, a number of mounting holes are provided through the top plate tie rod; a connecting bridge is fixedly installed in the mounting hole, and the two ends of the connecting bridge are respectively fixedly connected to the inner side wall of the mounting hole; the top ring is rotatably sleeved on the outer circumference of the connecting bridge and is rotatably installed in the mounting hole through the connecting bridge.

[0013] As a further improvement to this utility model, the top ring is set at equal intervals.

[0014] As a further improvement of this utility model, it also includes a fixing block and a base plate tie rod; one end of the base plate is fixedly connected to the support plate through the fixing block to form a fixed end;

[0015] The end of the base plate furthest from the fixed block is directly or indirectly connected to the base plate tie rod; the end of the base plate tie rod furthest from the base plate is directly or indirectly connected to the output end of the corresponding driver to drive the base plate tie rod to reciprocate in the vertical direction, thereby causing the base plate to move synchronously with the base plate tie rod.

[0016] As a further improvement of this utility model, a second opening groove is provided through the bottom plate, and a top ring is provided between the fixed end of the bottom plate and the support plate and the second opening groove.

[0017] As a further improvement of this utility model, the top plate tie rod is U-shaped; the bottom of the U-shape of the top plate tie rod is mounted on the bottom plate, and the top ring is rotatably sleeved on the bottom of the U-shape of the top plate tie rod.

[0018] As a further improvement of this utility model, it also includes a pull plate assembly, which is installed on the top of the base plate;

[0019] The pull plate assembly includes a first pull plate and a second pull plate; the first pull plate and the second pull plate are slidably disposed on the top of the base plate; the first pull plate and the second pull plate are matched and disposed together, and grooves are provided on opposite sides of the first pull plate and the second pull plate, and the two grooves are matched and disposed together to form a first opening groove; the first opening groove is disposed on the top of the second opening groove and is centrally symmetrical with the second opening groove in the vertical direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The solution of this utility model sets a support component between the support plate and the base plate assembly. When the base plate assembly moves downward, the support component assists in pressing the pressure plate assembly. This makes the tilt angle of the front and rear ends of the base plate set by the pressure plate assembly smaller than that of the existing design. This ensures that at the folding opening, the gap between the front side and the base plate and the gap between the rear side and the base plate are not much different, which allows the fabric to be folded smoothly.

[0021] The top ring of the support component works in conjunction with the rolling groove of the support plate. When the top ring rolls, the inclined rolling groove applies pressure to the bottom plate, thereby pressing the bottom plate and increasing the gap between the vertical pull plate and the bottom plate. This ensures that even if the rear end of the bottom plate is pressed down a short distance, the distance between the front side of the bottom plate and the folding opening can still be increased to a level that allows for folding. This avoids the problem that the front opening of the bag after the fabric is opened is blocked by the bottom plate in front of the folding opening, preventing the fabric from being folded smoothly on that side.

Figure 2 One end of the fourth drive component 10 is defined as the rear end of the bag opening component; Figure 2 The left side of the fixing block 53 is defined as the left end of the bag opening assembly, and the right side of the fixing block 53 is defined as the right end of the bag opening assembly; the above-mentioned orientation or positional relationship is based on the attached... Figure 2 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Please see Figure 1-8 A bag opening assembly for folding material in a bag opening machine includes a support plate 1, a cover plate 2, a pressure plate assembly 3, a pull plate assembly 4, a bottom plate assembly 5, a support assembly 6, a first drive assembly 7, two second drive assemblies 8, two third drive assemblies 9, two fourth drive assemblies 10, and a standing plate assembly.

[0035] The base plate assembly 5 includes a base plate 51, a fixing block 53, a base plate bracket 52, and a base plate tie rod 55; the bottom of the fixing block 53 is fixedly connected to the top of the front end of the base plate 51, and the top of the fixing block 53 is fixedly connected to the bottom of the front end of the support plate 1; the base plate 51 is fixedly connected to the support plate 1 through the fixing block 53; the rear end of the base plate 51 is movably set relative to the support plate 1.

[0036] The rear end of the base plate 51 is fixedly connected to the base plate bracket 52, and the end of the base plate bracket 52 away from the base plate 51 is installed and connected to the base plate tie rod 55. The top of the rear end of the base plate tie rod 55 passes through the support plate 1 to form a back plate, and the back plate is slidably disposed relative to the support plate 1. A linkage plate 56 is installed on the side wall of the back plate. The lower end of the linkage plate 56 is installed and connected to the back plate. The top of the linkage plate 56 is bent or folded to form a bend. The output end of the first drive assembly 7 is set upward and installed and connected to the bend to drive the linkage plate 56 to reciprocate in the vertical direction. The linkage plate 56 drives the back plate of the base plate tie rod 55 to reciprocate in the vertical direction, thereby driving the rear end of the base plate 51 to move along with the base plate tie rod 55.

[0037] The support assembly 6 includes several top rings 61 and top plate tie rods 62; the top rings 61 are rotatably disposed between the support plate 1 and the base plate 51, and are disposed near the fixed ends of the base plate 51 and the support plate 1; the top plate tie rods 62 are mounted above the base plate 51.

[0038] A number of mounting holes 621 are provided through the top plate tie rod 62; a connecting bridge 622 is fixedly installed in the mounting hole 621, and the two ends of the connecting bridge 622 are respectively fixedly connected to the inner side wall of the mounting hole 621; the top ring 61 is rotatably sleeved on the outer circumference of the connecting bridge 622; the top ring 61 is rotatably sleeved in the mounting hole 621 of the top plate tie rod 62 through the connecting bridge 622, and the bottom of the top ring 61 abuts against the top of the base plate 51.

[0039] The bottom of the support plate 1 is recessed and has several rolling grooves 101. The rolling grooves 101 are inclined relative to the horizontal direction of the top of the support plate 1 to form an inclined stepped layer, that is, the groove is deeper at the back and shallower at the front, and the groove depth changes linearly. The top of the top ring 61 is rolled in the corresponding rolling groove 101 and abuts against the inclined stepped layer. When the top ring 61 rolls between the bottom plate 51 and the support plate 1, due to the inclined setting of the rolling grooves 101, the top ring 61 rolls back and forth relative to the bottom plate 51. Due to the different distances between the inclined stepped layer and the bottom plate 51, pressure is applied to the front end of the bottom plate 51 by the top ring 61, thereby pressing the front end of the bottom plate 51. This makes the inclination angle of the front and rear ends of the bottom plate 51 smaller than that of the existing design when folding the material. This ensures that the gap between the front and rear sides of the bottom plate 51 at the folding opening is not much different, so that the fabric can be folded smoothly.

[0040] Preferably, each rolling groove 101 is set at equal intervals.

[0041] Preferably, each top ring 61 is set at equal intervals.

[0042] Preferably, the number of rolling grooves 101 is the same as the number of top rings 61.

[0043] A second opening groove is provided through the bottom plate 51, and the top ring 61 is located between the fixing block 53 and the second opening groove.

[0044] Preferably, the top ring 61 rolls relative to the second opening groove, that is, it rolls away from or close to the second opening groove.

[0045] A first tie rod bracket is installed at the output end of the second drive assembly 8. An extension rod is installed at the end of the first tie rod bracket away from the second drive assembly 8. The end of the extension rod away from the first tie rod bracket is connected to the end of the corresponding top plate tie rod 62 away from the top ring 61. The second drive assembly 8 drives the top plate tie rod 62 to reciprocate relative to the base plate 51 through the first tie rod bracket and the extension rod, thereby causing the top ring 61 to reciprocate on the base plate 51.

[0046] The top plate tie rod 62 is U-shaped; the bottom of the U-shape of the top plate tie rod 62 is mounted above the base plate 51, and the top ring 61 is rotatably sleeved on the bottom of the U-shape of the top plate tie rod 62.

[0047] The pull plate assembly 4 is installed on the top of the base plate 51; the pull plate assembly 4 includes a first pull plate 41 and a second pull plate 42; the first pull plate 41 and the second pull plate 42 are slidably disposed on the top of the base plate 51; the first pull plate 41 and the second pull plate 42 are matched and disposed together, and grooves are provided on opposite sides of the first pull plate 41 and the second pull plate 42, and the two grooves are matched and disposed together to form a first bag opening groove; the first bag opening groove is disposed on the top of the second bag opening groove and is symmetrically disposed with the second bag opening groove in the vertical direction.

[0048] A third bag opening groove is provided through the support plate 1. The third bag opening groove is symmetrically arranged with the first bag opening groove and the second bag opening groove in the vertical direction.

[0049] A first fixed frame is fixedly installed on the top of the first pull plate 41, and corresponding first pull rods 43 are respectively installed at both ends of the first fixed frame; a third pull rod bracket is installed at the end of the first pull rod 43 away from the first fixed frame; the output end of the third drive assembly 9 is connected to the end of the corresponding third pull rod bracket away from the first pull rod 43; the third drive assembly 9 ultimately drives the first pull plate 41 to reciprocate relative to the base plate 51.

[0050] A second fixed frame is fixedly installed on the top of the second pull plate 42, and corresponding second pull rods 44 are respectively installed at both ends of the second fixed frame; a fourth pull rod bracket is installed at the end of the second pull rod 44 away from the second fixed frame; the output end of the fourth drive assembly 10 is connected to the end of the corresponding fourth pull rod bracket away from the second pull rod 44; the fourth drive assembly 10 ultimately drives the second pull plate 42 to reciprocate relative to the base plate 51.

[0051] The third drive assembly 9 and the fourth drive assembly 10 respectively control the first pull plate 41 and the second pull plate 42 to move synchronously relative to each other, thereby controlling the two grooves to abut or move away from each other.

[0052] The support plate 1 has several through slots running from top to bottom. Each tie rod bracket passes through the through slot from the bottom of the support plate 1 and is installed and connected to the output end of the corresponding drive component. Each drive component is fixedly installed on the top of the support plate 1. The installation configuration of the above drive components is a common structure known to those skilled in the art, and will not be described in detail here.

[0053] The cover plate 2 is placed on the third bag opening groove and is fixedly connected to the support plate 1; a fourth bag opening groove is opened through the cover plate 2. The fourth bag opening groove is symmetrically arranged with the first, second and third bag opening grooves in the vertical direction to form a groove for opening the bag.

[0054] The upright plate assembly is fixedly mounted on the top of the support plate 1, and the pressure plate assembly 3 is slidably mounted on the upright plate assembly; the pressure plate of the pressure plate assembly 3 is mounted above the fourth bag opening groove; the pressure plate assembly 3 is common knowledge known to those skilled in the art, and will not be described in detail here.

[0055] Working principle:

[0056] When the first drive component 7 is powered on, its output drives the linkage plate 56 to move downward in the vertical direction; the lower end of the linkage plate 56 drives the bottom plate tie rod 55 to move downward synchronously, thereby driving the rear end of the bottom plate 51 to bend downward; since the front end of the bottom plate 51 is fixedly connected to the support plate 1, the rear end of the bottom plate 51 causes the front and rear connection distances between the bottom plate 51 and the tie plate to be inconsistent in the vertical direction during the downward movement, with a larger distance on one side and a smaller distance on the other side.

[0057] During the downward movement of the base plate 51, the top ring 61 in the support assembly 6 is driven by the top plate pull rod 62 driven by the second drive assembly 8 to make the top ring 61 roll above the base plate 51 and roll towards the first pocket groove. The top ring 61 of the support assembly cooperates with the rolling groove 101 of the support plate 1. When the top ring 61 rolls, due to the inclined setting of the rolling groove 101, the top ring 61 applies pressure to the front end of the base plate 51 when it rolls relative to the base plate 51, thereby pressing the base plate 51 and increasing the distance between the first pull plate 41 and the base plate 51 in the vertical direction.

[0058] Ultimately, this design results in a smaller tilt angle between the front and rear ends of the base plate 51 during folding compared to existing designs. This ensures that the gap between the front and rear sides of the base plate 51 at the folding point is not significantly different, allowing the fabric to be folded smoothly.

[0059] After the base plate 51 is pressed down, the opening of the bag after the fabric is opened is pressed by the folding mechanism and folded to the underside of the first pull plate 41 and the second pull plate 42 respectively. Then the first drive component 7 drives the base plate 51 to rise and press down the folded opening of the bag, thus realizing the folding step.

[0060] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
