Description

Technical Field

[0001] This utility model relates to the field of garment processing, and in particular, to a bag opening adjustment mechanism for a bag opening machine. Background Technology

[0002] In garment processing, pocket opening machines are essential auxiliary processing equipment. They are used to create slits in the garment and sew pockets onto it. To enable the equipment to process pockets of different sizes, the size of the pocket opening needs to be designed to be adjustable or replaceable.

[0003] For example, CN117306125A discloses a garment pocket-opening machine, including a first upper clamping plate and a second upper clamping plate. The first and second upper clamping plates can be docked or separated under the drive of a drive mechanism. Each of the first and second upper clamping plates corresponds to a drive mechanism, and docking or separation is achieved by simultaneously controlling their respective drive mechanisms. The docking points of the first and second upper clamping plates are provided with mutually adaptable notches. When the first and second upper clamping plates are docked, the two notches can close to form a rectangular material-fixing window. By simply driving the first and second upper clamping plates to move relative to each other, the four sides of the rectangular material-fixing window can be easily opened and closed. Through the continuous opening and closing of the rectangular material-fixing window, it can better cooperate with the folding mechanism for folding. Although the above structure can also achieve space size adjustment, setting four drive sources will increase the equipment cost, as more drive sources require more installation space. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a bag opening adjustment mechanism for a bag opening machine, which controls the size of the material setting window through two drive components.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a bag opening adjustment mechanism for a bag opening machine, including a base and a first seat. An opening fixing plate is provided on the first seat, and a sewing groove is provided on the opening fixing plate. A front push plate, a left push plate, a rear push plate, and a right push plate are arranged in sequence around the sewing groove. The front push plate, the left push plate, the rear push plate, and the right push plate form a material fixing window. A drive component one and a drive component two are provided on the first seat. A first linkage mechanism is provided at the output end of the drive component one. The drive component one drives the first linkage mechanism to control the front push plate and the rear push plate to move back and forth. A second linkage mechanism is provided at the output end of the drive component two. The drive component two drives the second linkage mechanism to control the left push plate and the right push plate to move left and right.

[0006] By employing the aforementioned technical means, the first linkage mechanism connects the drive assembly one to the front push plate and the rear push plate, and the second linkage mechanism connects the drive assembly two to the left push plate and the right push plate, thereby enabling the two drive sources to drive the front push plate and the rear push plate, the left push plate and the right push plate to move respectively. This reduces the number of drive sources required, reduces the space needed to install the drive sources, makes the equipment structure more compact, and reduces the production cost of the equipment.

[0007] Preferably, the drive assembly includes a lead screw motor, the first linkage mechanism includes a driven component, the front push plate is disposed at the output end of the lead screw motor, the driven component is disposed between the rear push plate and the front push plate, and the driven component drives the rear push plate and the front push plate to approach or move away from each other.

[0008] By using the above-mentioned technical means, by setting the front push plate at the output end of the first lead screw motor and setting a driven component between the rear push plate and the front push plate, the first lead screw motor drives the front push plate to move, thereby causing the rear push plate to move together.

[0009] Preferably, the driven component includes a driven frame and a hinge block. The driven frame is slidably disposed on the first seat, and the hinge block is rotatably disposed on the first seat. One end of the hinge block is hinged to the driven frame, and the other end is hinged to the tail of the front push plate.

[0010] By using the above-mentioned technical means, the movement of the front push plate drives the hinge block to rotate, which in turn pushes the driven frame to move, thereby causing the driven frame to move closer to or further away from the front push plate, achieving the purpose of one driving source simultaneously driving the front push plate and the rear push plate to move.

[0011] Preferably, a connecting plate 1 and a connecting plate 2 are provided between the front push plate and the lead screw motor 1. The connecting plate 1 is fixed at the output end of the lead screw motor 1, and the connecting plate 2 is fixedly provided between the connecting plate 1 and the front push plate. U-shaped openings are provided on both the driven frame and the connecting plate 2. Round-headed sliders are provided at both ends of the hinge block and rotate and slide with the two U-shaped openings.

[0012] Through the aforementioned technical means, and by cooperating between the U-shaped opening and the round-headed slider, it is ensured that the hinge plate only drives the driven frame to move in the Y-axis direction during rotation.

[0013] Preferably, the second drive assembly includes a second lead screw motor, and the second linkage mechanism includes a first rocker arm, a second rocker arm, and a power push plate. The left push plate and the right push plate are respectively disposed at the tail ends of the first rocker arm and the second rocker arm. The heads of the first rocker arm and the second rocker arm are respectively fixed to the two sides of the power push plate. The power push plate is disposed at the output end of the second lead screw motor. When the second lead screw motor drives the power push plate to move, the first rocker arm and the second rocker arm drive the left push plate and the right push plate to move closer to or further away from each other.

[0014] Through the above-mentioned technical means, and through the cooperation between the power push plate and the first and second swing rods, the second screw motor drives the power push plate to move, while the first and second swing rods drive the left and right push plates to move respectively, so as to realize that one drive source drives the left and right push plates to move simultaneously.

[0015] Preferably, the first and second swing arms have the same structure and are symmetrically arranged. The first and second swing arms are both hinged to the first seat. Both ends of the power push plate are provided with an elongated hole. The head of the first and second swing arms is provided with a sliding rod. The sliding rod slides in the elongated hole. The tail of the first and second swing arms is provided with an elongated hole. The tail of the left and right push plates is provided with a sliding rod. The sliding rod slides in the elongated hole. When the second lead screw motor drives the power push plate to move, the power push plate drives the first and second swing arms to swing around the hinge point and drives the left and right push plates to move.

[0016] Through the above-mentioned technical means, the first and second swing rods are hinged on the first seat, and the first slide rod cooperates with the first long waist hole, so that when the power push plate moves in the Y-axis direction, the first and second swing rods swing, thereby driving the left push plate and the right push plate to move in the X-axis direction.

[0017] Preferably, it further includes a second seat, a third seat, a first pressure plate, and a second pressure plate. The first seat is slidably connected to the base in a vertical direction, and the first seat is provided with a first driving member for driving the first seat to slide.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0028] A bag opening adjustment mechanism for a bag opening machine includes a base and a first seat 31. An opening fixing plate 311 is provided on the first seat 31. A sewing groove 312 is formed on the opening fixing plate 311. A front push plate 313, a left push plate 315, a rear push plate 314, and a right push plate 316 are arranged sequentially around the sewing groove 312. The front push plate 313, left push plate 315, rear push plate 314, and right push plate 316 form a material fixing window 318. A drive assembly 3 is provided on the first seat 31. 2. Drive component 2 33. The output end of drive component 1 32 is provided with a first linkage mechanism 34. Drive component 1 32 drives the first linkage mechanism 34 to control the movement of the front push plate 313 and the rear push plate 314, and controls the width of the material setting window 318. The output end of drive component 2 33 is provided with a second linkage mechanism 35. Drive component 2 33 drives the second linkage mechanism 35 to control the movement of the left push plate 315 and the right push plate 316, and controls the length of the material setting window 318.

[0029] The first linkage mechanism 34 connects the drive assembly 32 to the front push plate 313 and the rear push plate 314, and the second linkage mechanism 35 connects the drive assembly 33 to the left push plate 315 and the right push plate 316. This allows the two drive sources to drive the front push plate 313 and the rear push plate 314, the left push plate 315 and the right push plate 316 to move respectively. This reduces the number of drive sources required, reduces the space needed to install the drive sources, makes the equipment structure more compact, and reduces the production cost of the equipment.

[0030] The drive assembly 32 includes a lead screw motor 321, which includes a motor, a lead screw with a motor output end, and a slider. The first linkage mechanism 34 includes a driven assembly 341. The front push plate 313 is fixed to the slider at the output end of the lead screw motor 321. The driven assembly 341 is disposed between the rear push plate 314 and the front push plate 313. The driven assembly 341 drives the rear push plate 314 and the front push plate 313 to approach or move away from each other.

One end of the hinge block 343 is hinged to the driven frame 342. The end is hinged to the side end of the connecting plate 345. Both the driven frame 342 and the connecting plate 345 have U-shaped openings 346. Both ends of the hinge block 343 are provided with round-headed sliders 347, which rotate and slide in cooperation with the two U-shaped openings 346. The movement of the front push plate 313 drives the hinge block 343 to rotate, which in turn pushes the driven frame 342 to move. This causes the driven frame 342 to move closer to or further away from the front push plate 313, achieving the purpose of one driving source simultaneously driving the front push plate 313 and the rear push plate 314 to move.

[0032] Drive assembly 2 33 includes lead screw motor 2 331, which has the same structure as lead screw motor 1 321.

The heads of rocker arm 1 351 and rocker arm 2 352 are respectively fixed to both sides of the power push plate 353. The power push plate 353 is located at the output end of lead screw motor 2 331. When the drive plate 353 moves, the first rocker arm 351 and the second rocker arm 352 drive the left push plate 315 and the right push plate 316 to move closer or further apart. Through the cooperation between the drive plate 353 and the first rocker arm 351 and the second rocker arm 352, the second lead screw motor 331 drives the left push plate 315 and the right push plate 316 to move respectively when the drive plate 353 moves, so as to achieve the purpose of one drive source driving the left push plate 315 and the right push plate 316 to move simultaneously.

[0033] The first swing arm 351 and the second swing arm 352 have the same structure and are symmetrically arranged. Both swing arms 351 and 352 are hinged to the first seat 31.

The tails of both swing arms 351 and 352 are provided with elongated slots 356. The tails of the left push plate 315 and the right push plate 316 are provided with sliding rods 357, which slide within the elongated slots 356. Inside 356, when the second lead screw motor 331 drives the power push plate 353 to move, the power push plate 353 drives the first swing rod 351 and the second swing rod 352 to swing around the hinge point and drive the left push plate 315 and the right push plate 316 to move. The first swing rod 351 and the second swing rod 352 are hinged on the first seat 31, and through the cooperation of the first slide rod 355 and the first long waist hole 354, when the power push plate 353 moves in the Y-axis direction, the first swing rod 351 and the second swing rod 352 swing, thereby driving the left push plate 315 and the right push plate 316 to move in the X-axis direction.

[0034] By using two driven methods, the front push plate 313 and the rear push plate 314, and the left push plate 315 and the right push plate 316 can move relative to each other, so that the first lead screw motor 321 and the second lead screw motor 331 can be set on the same side, and the electrical components can be set in the same position to ensure more convenient circuit connection. Two lead screw motors are used when bending materials.

[0035] It also includes a first seat 31, a second seat 36, a third seat 37, a first pressure plate 371, and a second pressure plate 372. The first seat 31 is slidably connected to the base in the vertical direction. The first seat 31 is provided with a first driving member 317 for driving the first seat 31 to slide. The second seat 36 is slidably connected to the first seat 31 in the vertical direction. The second seat 36 is provided with a second driving member 361 for driving the second seat 36 to slide. The third seat 37 is slidably connected to the second seat 36 in the vertical direction. The second seat 36 is provided with a third driving member 362 for driving the third seat 37 to slide. The first pressure plate 371 is disposed on the second seat 36, and the second pressure plate 372 is disposed on the third seat 37. The second pressure plate 372 is located inside the first pressure plate 371 and is used to press the two ends of the fabric in the length direction within the working area.

The second seat 36 is slidably connected to the first seat 31 in a vertical direction. The second seat 36 is provided with a second driving member 361 for driving the second seat 36 to slide. The third seat 37 is slidably connected to the second seat 36 in a vertical direction. The second seat 36 is provided with a third driving member 362 for driving the third seat 37 to slide.

[0037] The first driving member 317, the second driving member 361, and the third driving member 362 are all driven by cylinders or oil cylinders.

[0038] The first pressing plate 371 is arranged in a hollow frame shape and is used to press the fabric. The inside of the first pressing plate 371 is the working area of the fabric. The folding mechanism is arranged on the first base 31 and is used to fold the folded edges after cutting the fabric in the working area. The first pressing plate 371 is arranged on the second base 36, and the second pressing plate 372 is arranged on the third base 37. The second pressing plate 372 is located inside the first pressing plate 371 and is used to press both ends of the fabric in the length direction in the working area.

[0039] The first pressing plate 371 can initially limit the position of the fabric. Since there are only two long folded edges after laser cutting, the fabric without folded edges in the length direction has no additional position limitation and is prone to displacement and deformation. The second pressing plate 372 can press both ends of the fabric in the length direction in the working area, so that the fabric is not prone to displacement and deformation during sewing, and the flatness of the fabric after sewing can be improved.

[0040] The second pressing plate 372 is arranged in a "C" shape and presses one end of the fabric in the width direction and both ends of the fabric in the length direction in the working area respectively. The "C"-shaped second pressing plate 372 has good stability and can also re-limit the position of one of the folded edges in the width direction that has been folded.

[0041] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
