Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to an automatic garment bag opening machine and its bottom mold clamping and positioning mechanism. Background Technology

[0002] In fully automatic garment pocket-opening machines, the bottom mold clamping mechanism is a key component for achieving accurate and stable conveying of the bottom mold tray. Traditional bottom mold clamping mechanisms typically employ a planar contact positioning structure, where the clamping component and the tray assembly achieve positioning through planar contact. However, in actual operation, when the mechanism is subjected to external forces such as material impact or equipment vibration, the bottom mold tray assembly is prone to lateral sliding, causing the clamping position to shift, which in turn leads to misalignment of the cut pieces and affects the accuracy of subsequent sewing positions.

[0003] To address the positioning deviation problem, existing technologies have attempted to optimize the process by increasing clamping force and adding guide blocks. However, increasing clamping force can lead to increased wear on parts, while adding guide blocks increases the complexity of the mechanism and the difficulty of assembly. Neither approach can fundamentally solve the problem of sliding offset of the bottom mold support plate assembly. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic garment bag opening machine and its bottom mold clamping and positioning mechanism, which has the advantage of preventing the bottom mold from sliding.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution: According to the embodiments disclosed in this utility model, a first aspect provides a bottom mold clamping and positioning mechanism for an automatic garment bag opening machine, comprising: Mounting brackets for assembly with the frame of a bag-opening machine; A clamping assembly for holding a bottom mold support plate is slidably mounted on the mounting bracket. One side of the bottom mold support plate is provided with a limiting clamping strip. The upper surface of the limiting clamping strip has a first clamping contact surface that is either upwardly protruding or downwardly recessed. The clamping assembly includes a chuck for clamping the limiting clamping strip, and the chuck has a second clamping contact surface that abuts against the first clamping contact surface. A transfer drive assembly supported on the mounting bracket for driving the clamping assembly to reciprocate.

[0006] To achieve the above technical solution, when transferring the bottom mold tray, the transfer drive assembly drives the clamping assembly to move to the predetermined clamping position. After the bottom mold tray is in place, the clamping assembly controls the clamping head to clamp the limiting clamping strip. At this time, the first clamping contact surface and the second clamping contact surface are in contact, achieving a stable clamping and positioning effect. Then, the transfer drive assembly drives the clamping assembly to move, transferring the bottom mold tray to the bag opening position. Then, the clamping assembly is released, completing one transfer process and waiting for the next clamping requirement. Since the first clamping contact surface and the second clamping contact surface are in a concave-convex fit, the left and right sliding of the bottom mold tray can be effectively restricted, improving the subsequent clamping accuracy. Moreover, there is no need to add complex guide components. Positioning optimization is achieved only by optimizing the shape of the contact surface. The structure is simpler and easier to process, reducing the number of parts, reducing assembly difficulty and equipment failure rate.

[0007] In one embodiment of the present invention, the clamping assembly includes: A sliding base is used for sliding assembly with the mounting bracket, and a clamping and fixing surface is formed on the sliding base; A clamping cylinder is fixed to the sliding base. The chuck is fixed to the power output end of the clamping cylinder and corresponds to the clamping fixing surface. The second clamping contact surface is located on the side of the chuck that corresponds to the clamping fixing surface.

[0008] To achieve the above technical solution, the sliding base serves as the installation foundation to enable the overall sliding of the clamping assembly. The clamping cylinder drives the chuck to clamp or release the bottom mold plate. The clamping fixing surface supports the bottom of the bottom mold plate, and the chuck clamps the upper part of the bottom mold plate to achieve the clamping and positioning of the bottom mold plate.

[0009] In one embodiment of the present invention, the first clamping contact surface is upwardly convex, and the second clamping contact surface is correspondingly inwardly concave.

[0010] To achieve the above technical solution, since the size of the limiting clamping bar is limited, it is easier to process the first clamping contact surface by adopting an upward convex shape, and it can ensure sufficient structural strength.

[0011] In one embodiment of this utility model, the first clamping contact surface is arc-shaped, triangular, or polygonal.

[0012] In one embodiment of this utility model, the first clamping contact surface is arc-shaped.

[0013] To achieve the above technical solution, the arc-shaped fitting structure can effectively resist the influence of external forces such as material impact and vibration on positioning, which is conducive to improving the stability of the mechanism operation, extending the service life of parts, and avoiding adverse situations such as wear caused by excessive clamping.

[0014] In one embodiment of the present invention, the sliding base includes: a sliding seat for sliding assembly with the mounting bracket, and a power seat fixed to the sliding seat, the power seat being used for assembly with the moving part of the transfer drive assembly.

[0015] To achieve the above technical solution, the sliding seat is designed to facilitate sliding connection with the mounting bracket, and the power seat is designed to facilitate connection with the transfer drive assembly to achieve power transmission.

[0016] In one embodiment of the present invention, the transfer drive assembly is selected individually or in combination from the following structures: belt assembly, lead screw assembly, or sprocket assembly.

[0017] In one embodiment of the present invention, the transfer drive assembly is a belt assembly, which includes: a transmission belt assembly, a drive motor fixed to the mounting bracket, and a power transmission component connected to the power output end of the transmission belt assembly and the drive motor, wherein the power base is fixed to the transmission belt assembly.

[0018] The above technical solution is lower in cost and easier to install.

[0019] In one embodiment of this utility model, the power transmission component is selected individually or in combination from the following structures: belt assembly, gear assembly, or sprocket and chain assembly.

[0020] According to the embodiments disclosed in this utility model, a second aspect provides an automatic garment bag opening machine, including the bottom mold clamping and positioning mechanism as described in the first aspect.

[0021] As described above, the present invention has the following beneficial effects: This invention provides an automatic garment bag opening machine and its bottom mold clamping and positioning mechanism. The bottom mold clamping and positioning mechanism includes: a mounting bracket for assembly with the frame of the bag opening machine; a clamping assembly slidably mounted on the mounting bracket for clamping a bottom mold support plate, wherein a limiting clamping strip is provided on one side of the bottom mold support plate, and the upper surface of the limiting clamping strip is provided with a first clamping contact surface that is raised upward or recessed downward; the clamping assembly includes a clamping head for clamping the limiting clamping strip, and the clamping head is provided with a second clamping contact surface that fits against the first clamping contact surface; and a transfer drive assembly supported on the mounting bracket for driving the clamping assembly to reciprocate. When transferring the bottom mold tray, the transfer drive assembly drives the clamping assembly to move to the predetermined clamping position. After the bottom mold tray is in place, the clamping assembly controls the clamping head to clamp the limiting clamping strip. At this time, the first clamping contact surface and the second clamping contact surface are in contact, achieving a stable clamping and positioning effect. Then, the transfer drive assembly drives the clamping assembly to move, transferring the bottom mold tray to the bag opening position. Then, the clamping assembly is released, completing one transfer process and waiting for the next clamping requirement. Since the first clamping contact surface and the second clamping contact surface are in a concave-convex fit, the left and right sliding of the bottom mold tray can be effectively restricted, improving the subsequent clamping accuracy. Moreover, there is no need to add complex guide components. Positioning optimization is achieved only by optimizing the shape of the contact surface. The structure is simpler and easier to process, reducing the number of parts, reducing assembly difficulty and equipment failure rate. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figures 1 to 4 The first aspect of this utility model provides a bottom mold clamping and positioning mechanism for an automatic garment bag opening machine, comprising: a mounting bracket 10 for assembly with the frame of the bag opening machine; a clamping assembly 20 slidably mounted on the mounting bracket 10 for clamping a bottom mold support plate 40, wherein a limiting clamping strip 41 is provided on one side of the bottom mold support plate 40, and the upper surface of the limiting clamping strip 41 is provided with a first clamping contact surface 42 that is raised upward or recessed downward; the clamping assembly 20 includes a clamping head 23 for clamping the limiting clamping strip 41, and the clamping head 23 is provided with a second clamping contact surface 231 that fits against the first clamping contact surface 42; and a transfer driving assembly 30 supported on the mounting bracket 10 for driving the clamping assembly 20 to reciprocate.

[0029] Specifically, the mounting bracket 10 provides a mounting base for the clamping assembly 20 and the transfer drive assembly 30. The clamping assembly 20 includes: a sliding base 21 for sliding assembly with the mounting bracket 10, and a clamping fixing surface 211 formed on the sliding base 21; a clamping cylinder 22 fixed to the sliding base 21; a chuck 23 fixed to the power output end of the clamping cylinder 22 and corresponding to the clamping fixing surface 211; and a second clamping contact surface 231 located on the side of the chuck 23 corresponding to the clamping fixing surface 211.

[0030] The clamping cylinders 22 can be set in several groups. It is understood that the longer the size of the configured clamping head 23, the more clamping cylinders 22 need to be set. Preferably, in this embodiment, two sets of clamping cylinders 22 are set. The clamping fixing surface 211 is formed on the top of the sliding base 21. The sliding base 21 serves as the installation base to realize the overall sliding of the clamping assembly 20. The clamping cylinders 22 drive the clamping head 23 to achieve the clamping or loosening of the bottom mold support plate 40. The clamping fixing surface 211 supports the bottom of the bottom mold support plate 40, and the clamping head 23 clamps the upper part of the bottom mold support plate 40 to achieve the clamping and positioning of the bottom mold support plate 40.

[0031] The sliding base 21 includes: a sliding seat 212 for sliding assembly with the mounting bracket 10, and a power seat 213 fixed to the sliding seat 212. The power seat 213 is used to assemble with the moving parts of the transfer drive assembly 30. One side of the sliding seat 212 is connected to a mounting side plate by means of bolt connection, integral molding, etc. The clamping cylinder 22 is fixed to the mounting side plate. The sliding seat is designed to facilitate sliding connection with the mounting bracket 10, and the power seat 213 is designed to facilitate connection with the transfer drive assembly 30 to realize power transmission.

[0032] The limiting clamping strip 41 is fixed to one side edge of the bottom mold support plate 40. Similar to the prior art, a bottom mold fixing plate 43 is also fixed on the bottom mold support plate 40 for the gripping device on the bag opening machine to grip and fix the bottom mold support plate 40. The first clamping contact surface 42 is convex upward and the second clamping contact surface 231 is concave inward. Since the size of the limiting clamping strip 41 is limited, it is easier to process the first clamping contact surface 42 by adopting an upward convex shape, and it can ensure sufficient structural strength.

[0033] The first clamping contact surface 42 is arc-shaped, triangular, or polygonal. Preferably, the first clamping contact surface 42 is arc-shaped, and correspondingly, the second clamping contact surface 231 is concave arc-shaped. The arc-shaped fitting structure can effectively resist the influence of external forces such as material impact and vibration on positioning, which is conducive to improving the stability of the mechanism operation, extending the service life of parts, and avoiding adverse conditions such as wear caused by excessive clamping.

[0034] The transfer drive assembly 30 can be selected individually or in combination from the following structures: belt assembly, lead screw assembly, or sprocket assembly. In this embodiment, the transfer drive assembly 30 preferably uses a belt assembly, which includes: a drive belt assembly 31, a drive motor 32 fixed to the mounting bracket 10, and a power transmission component 33 connected to the power output end of the drive belt assembly 31 and the drive motor 32. The power seat 213 is fixed to the drive belt assembly 31, resulting in lower cost and easier installation. The power transmission component 33 can be selected individually or in combination from the following structures: belt assembly, gear assembly, or sprocket and chain assembly. The power transmission component 33 preferably uses a belt assembly.

[0035] When transferring the bottom mold tray 40, the transfer drive assembly 30 drives the clamping assembly 20 to move to the predetermined clamping position. After the bottom mold tray 40 is in place, the clamping assembly 20 controls the clamping head 23 to clamp the limiting clamping strip 41. At this time, the first clamping contact surface 42 and the second clamping contact surface 231 are in contact, achieving stable clamping and positioning. Then, the transfer drive assembly drives the clamping assembly 20 to move and transfer the bottom mold tray 40 to the bag opening position. Then, the clamping assembly 20 is released, thus completing one transfer process and waiting for the next clamping requirement. Since the first clamping contact surface 42 and the second clamping contact surface 231 are in a concave-convex fit, the left and right sliding of the bottom mold tray 40 can be effectively restricted, improving the subsequent clamping accuracy. Moreover, there is no need to add complex guide components. Positioning optimization is achieved only by optimizing the shape of the contact surface. The structure is simpler and easier to process, reducing the number of parts, reducing assembly difficulty and equipment failure rate.

[0036] The second aspect of this utility model provides an automatic garment bag opening machine, including a bottom mold clamping and positioning mechanism as described in the first aspect. It is understood that the mounting bracket 10 is fixed to the frame of the automatic garment bag opening machine.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
