Abstract
Description
Technical Field
[0001] This utility model relates to the field of pocket processing technology, and in particular to a clamping structure for a pocket opening machine clip. Background Technology
[0002] In garment manufacturing, 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 process involves first processing the pocket opening and the pocket lip separately, then sewing the lip onto the opening to complete the pocket opening. The processing of the pocket opening requires cutting, folding, shaping, and sewing the pocket opening area. Cutting involves creating "H" or "Y" shaped slits on the pocket opening; folding involves folding the cut pocket opening inwards to form a folded edge; shaping involves placing the lip on the folded edge; and finally, sewing is performed. For example, utility model patent application number CN202010348853.X discloses a pocket opening machine for processing garment pocket openings; utility model patent application number CN202011214831.0 discloses a continuous production garment pocket opening machine.
[0003] However, when cutting and folding the bag opening, it is necessary to use a folding knife to fold the bag opening inward into the window of the outer frame to form a folded edge, and use clips to hold and fix the folded edge of the bag opening to prevent the folding knife from bringing the folded edge of the bag opening back during the retraction process.
[0004] Currently, the installation of clips on the market is generally divided into three categories: 1. The rear end of the clip is connected to an external drive source, and the front end is suspended; 2. The rear end of the clip is connected to an external drive source, and the front end is fixed; 3. The rear end of the clip is connected to an external drive source, and the front end is suspended, with an external pressure structure pressing against the front end when the clip needs to clamp the flange. However, the above three common installation methods have certain drawbacks, such as: 1. The clamping force at the front end of the clip is small, which cannot guarantee effective clamping of the bag opening flange; 2. Although the clamping force at the front end of the clip is large, the clip deforms significantly during lifting and lowering, easily causing deformation and damage; 3. The clips are costly to use and their operation is complex. Improvements are urgently needed to address these issues. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a clamping structure for the clamping plate of a bag opening machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clamping structure for a bag opener includes an outer pressure frame, a clamping piece is ellipsably disposed below the outer pressure frame, and an elastic abutment is mounted on the clamping piece, one end of which extends onto the outer pressure frame. The elastic abutment has a pressing end that can deform and press against the upper end of the outer pressure frame and drive the clamping piece to press against the outer pressure frame upward.
[0008] Preferably, the elastic abutment has a bending section capable of bending and deforming, and the pressing end abuts against the outer pressure frame through the bending section.
[0009] Preferably, the elastic abutment is disposed at the front end of the clamping piece, and the outer pressure frame has a notch for avoiding the installation of the elastic abutment.
[0010] Preferably, the number of elastic tabs is multiple and they are installed at intervals on the clips.
[0011] Preferably, the outer pressure frame has a window, and the clamping piece includes a front clamping piece and a rear clamping piece arranged opposite each other below the window. The rear clamping piece is connected to a driving component for driving its lifting and lowering. The front clamping piece is connected to the rear clamping piece via a reinforcing piece, and the elastic abutment is fixedly installed on the front clamping piece.
[0012] Preferably, a drive plate is connected to the drive end of the drive component, and the fixing plate and reinforcing plate of the rear clamp are both fixed to the drive plate.
[0013] Preferably, the rear clamp is equipped with an adjustment plate, and the rear clamp is adjusted by the front and rear displacement of the adjustment plate and fixed to the fixing plate.
[0014] Preferably, the outer pressure frame is fixed with a mounting plate for mounting the drive component.
[0015] The beneficial effects of this utility model are:
[0016] 1. An elastic abutment is provided on the clamping piece. When the clamping piece is driven to move downward, the front end of the clamping piece abuts against the outer pressure frame through the elastic deformation of the elastic abutment. When the clamping piece moves upward, the front end of the clamping piece is subjected to the upward force of the elastic abutment, so that the front end of the clamping piece can clamp the bag opening flange more stably and reliably, thereby ensuring the clamping effect of the bag opening flange. At the same time, the structure of this utility model is simple, the clamping is reliable, and it is suitable for widespread promotion and application.
[0017] 2. A reinforcing piece is connected between the front and rear clamping pieces of the clamping piece to enhance the structural strength of the front clamping piece, making it less prone to deformation and damage during clamping, thereby improving the quality and lifespan of the clamping piece.
[0018] 3. A drive unit is provided on the rear clamping piece to drive the clamping piece to rise and fall, and it cooperates with the elastic abutment on the front clamping piece so that when the clamping piece clamps the bag opening flange, an upward clamping force can be applied to the clamping piece from the front and rear sides, so that the clamping piece can more evenly flatten and clamp the bag opening flange, thereby improving the clamping effect.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] like Figures 1-5 As shown, a clamping structure for a bag opening machine clamp includes an outer pressure frame 1. A clamp is vertically mounted below the outer pressure frame 1. The clamp can be driven to move upward and fit against the lower end of the outer pressure frame 1 to clamp the flange of the bag opening. An elastic abutment 22 is mounted on the clamp, with one end extending from the outer pressure frame 1. The elastic abutment 22 is located at the front end of the clamp. One end of the elastic abutment 22 is detachably fixed to the clamp by a bolt, and the other end of the elastic abutment 22 abuts against the upper end of the outer pressure frame 1.
[0028] Specifically, the elastic abutment 22 has an abutment end 221 that can deform and press against the upper end of the outer pressure frame 1 and drive the clamping piece to press against the outer pressure frame 1 upward, and a bending section 222 that can be bent and deformed. The abutment end 221 abuts against the outer pressure frame 1 through the bending section 222. When the clamping piece moves downward, the elastic abutment 22 bends and deforms through the bending section 222 so that the abutment end 221 can always press against the outer pressure frame 1. That is, the front end of the clamping piece is elastically deformed by the elastic abutment 22 and always abuts against the outer pressure frame 1.
[0029] When the clip moves upward, the front end of the clip is subjected to the upward force of the elastic abutment 22, which enables the front end of the clip to clamp the bag opening more stably and reliably, so as to ensure the clamping effect of the bag opening. At the same time, the structure of this embodiment is simple, the clamping is reliable, and it is suitable for widespread application.
[0030] To further enhance the effect of the elastic tabs 22 in clamping the bag opening and turning the edge, multiple elastic tabs 22 are installed on the clamp at intervals. The multiple elastic tabs 22 are arranged at intervals on the front side of the clamp, so that the multiple elastic tabs 22 cooperate to apply a more uniform clamping force to the front end of the clamp. The outer pressure frame 1 has a notch 12 to avoid the installation of the elastic tabs 22. The notch 12 is distributed one-to-one with the elastic tabs 22. The pressing end 221 abuts against the upper surface of the outer pressure frame 1 through the notch 12.
[0031] The outer pressure frame 1 has a window 11. The clamping piece includes a front clamping piece 2 and a rear clamping piece 3 arranged opposite each other below the window 11. The rear clamping piece 3 is connected to a driving component 4 for driving it to rise and fall. The driving component 4 can be a driving cylinder. The outer pressure frame 1 is fixed with a mounting plate 13 for mounting the driving component 4.
[0032] The front clamping piece 2 is connected to the rear clamping piece 3 via the reinforcing piece 21. The driving end of the driving component 4 is connected to the driving plate 41. The fixing plate 31 and the reinforcing piece 21 of the rear clamping piece 3 are both fixed on the driving plate 41. That is, the front clamping piece 2 and the rear clamping piece 3 maintain synchronous driving lifting and lowering action through the reinforcing piece 21 and the rear clamping piece 3.
[0033] Furthermore, by connecting a reinforcing piece 21 between the front clamping piece 2 and the rear clamping piece 3, the structural strength of the front clamping piece 2 is enhanced by the reinforcing piece 21, making the front clamping piece 2 less prone to damage due to deformation during clamping, thereby improving the quality and lifespan of the clamping piece.
[0034] The elastic abutment 22 is fixedly installed on the front clamping piece 2, and the elastic abutment 22 is distributed on the front side of the front clamping piece 2. When the driving member 4 drives the rear clamping piece 3 to move up and down, it can cooperate with the elastic abutment 22 on the front clamping piece 2 so that when the clamping piece holds the bag opening flange, it can apply an upward clamping force to the clamping piece from the front and rear sides (the driving member 4 on the rear clamping piece 3 applies an upward clamping force to the rear side of the clamping piece, and the elastic abutment 22 on the front clamping piece 2 applies an upward elastic clamping force to the front side of the clamping piece), so that the clamping piece can more evenly flatten and clamp the bag opening flange, thereby improving the clamping effect.
[0035] An adjusting piece 32 is installed on the rear clamp 3. The rear clamp 3 is adjusted back and forth by the adjusting piece 32 and fixed on the fixing plate 31 so that the relative position of the rear clamp 3 with the front clamp 2 can be adjusted back and forth by the adjusting piece 32.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
