Description

Technical Field

[0001] This utility model relates to the field of bag production technology, and in particular to a pressing machine for bag production. Background Technology

[0002] A bag is a container used to carry items, typically made of leather, fabric, plastic, or other materials, and comes in various styles and functions. In existing technologies, the bag manufacturing process requires pressing the fabric. By applying pressure to the fabric, it can be shaped according to molds or design requirements, such as the corners and curves of the bag, helping to shape the overall appearance of the bag, making it more regular and aesthetically pleasing. Pressing equipment can enhance the fit, smooth the surface, and strengthen the texture.

[0003] Chinese patent document CN216832709U discloses a pressing device for bag production. By setting a connecting rod, the hinge seat can be fixed. When the pressing plate descends, the connecting frame drives the roller brush to flatten the fabric, increasing the flatness during pressing and reducing manual operation. When the support plate rises, it also drives the hinge seat to rise, so that the roller brush at the bottom of the hinge seat returns to its initial position under the influence of gravity, making it easy to use for the next time. This solves the problem that in the past, bag fabric had to be manually flattened before pressing.

[0004] The existing technology has the following problems:

[0005] The aforementioned equipment uses roller brushes at the bottom of two hinged seats to flatten the fabric. However, the roller brushes rotate as the pressing plate moves downwards. When the pressing plate contacts the fabric surface, the two roller brushes rotate to their maximum range, only able to flatten the fabric, but unable to hold fabrics of different sizes in place. Furthermore, for some stiff fabrics with uneven surfaces, even if the roller brushes roll over them, the lack of a structure to hold the fabric in place will affect subsequent pressing operations.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5As shown, a pressing machine for bag production includes a base 1, a worktable 4 is fixedly installed in the middle of the upper end of the base 1, a fixed adjustment component 2 is fixedly installed at the four corners of the upper end of the base 1, a buffer squeezing component 3 is fixedly installed in front and behind the fixed adjustment component 2, and a pressing component 5 is fixedly installed in the rear of the upper end of the base 1.

[0028] The fixed adjustment assembly 2 includes a movable frame 21 located above the workbench 4. Connecting frames 22 are fixedly installed on the front and rear parts of the left and right sides of the movable frame 21. Hydraulic rods 23 are fixedly installed at the four corners of the upper end of the base 1. The output ends of the four hydraulic rods 23 are fixedly connected to the bottom of the four connecting frames 22. Slide plates 24 are movably connected to the left and right parts of the front and rear sides of the movable frame 21. Rotating plates 25 are rotatably connected to the four adjacent slide plates 24 on the side away from each other. Rollers 26 with a surface of pile are rotatably connected to the opposite sides of the bottom of the four adjacent rotating plates 25.

[0029] The buffer compression assembly 3 includes four adjusting rods 31. The bottom of the four adjacent adjusting rods 31 on opposite sides is rotatably connected to the middle of the four rotating plates 25 on opposite sides. The top of the four adjacent adjusting rods 31 on opposite sides is movably connected to the four sliding plates 24 on opposite sides, away from the four rotating plates 25.

[0030] The fixed adjustment component 2 allows for flexible adjustment of the height and position of the roller 26 according to the different sizes, shapes, and pressing requirements of the bag fabric, adapting to various types of bag production and improving the equipment's versatility. The buffer extrusion component 3 ensures that the roller 26 applies uniform and moderate pressure to the bag fabric, allowing for better bonding of different parts of the fabric during the pressing process, thus improving the quality and stability of the pressing.

[0031] like Figure 4 and Figure 5 As shown, a mounting frame 27 is fixedly installed on the front side of the movable frame 21. A bidirectional lead screw 28 is rotatably connected to the inner wall of the mounting frame 27. A motor 29 is fixedly installed on the right side of the mounting frame 27. The output end of the motor 29 passes through the right side of the mounting frame 27 and is fixedly connected to the right end of the bidirectional lead screw 28. Slider 210s are threadedly connected to the left and right sides of the outer wall of the bidirectional lead screw 28. The front sides of the two sliders 210s are fixedly connected to the middle of the rear side of the two front slide plates 24.

[0032] According to the size of the fabric laid flat on the worktable 4, the output end of the motor 29 can drive the bidirectional lead screw 28 to rotate. The two sliders 210 are connected to the bidirectional lead screw 28 by threads, which drives the two front slide plates 24 to move closer or further apart. The four slide plates 24 move synchronously because of the connection of the two rollers 26, so that the two rollers 26 can fix fabrics of different sizes.

[0033] like Figure 4As shown, a moving groove 211 for two matching sliders 210 is provided through the center of the front side of the mounting frame 27.

[0034] like Figure 4 As shown, a guide post 212 is fixedly installed in the middle of the rear side of the movable frame 21. A connecting block 213 is slidably connected to the left and right sides of the outer side of the guide post 212. The rear side of the two connecting blocks 213 is fixedly connected to the middle of the front side of the two rear sliding plates 24.

[0035] The guide post 212 guides the movement of the two rollers 26.

[0036] like Figure 5 As shown, positioning frames 32 are fixedly installed on the four sliding plates 24 at positions away from each other and away from the four rotating plates 25. Slide grooves 33 are opened through the middle of the upper and lower ends of the four positioning frames 32. Limiting blocks 34 are slidably connected to the inner walls of the eight adjacent slide grooves 33. The tops of the opposite sides of the four adjacent adjusting rods 31 are rotatably connected to the sides of the four limiting blocks 34 away from each other.

[0037] When the four hydraulic rods 23 move the moving frame 21 downward, the four rollers 26 contact the fabric on the surface of the worktable 4. The four rotating plates 25 drive the four rollers 26 to rotate, thereby causing the four adjusting rods 31 to rotate. The four adjusting rods 31 drive the four limiting blocks 34 to slide in the corresponding positioning frames 32. When the spring 35 is under force, it will play a buffering role, which can ensure that the rollers 26 apply uniform and moderate pressure to the bag fabric.

[0038] like Figure 5 As shown, springs 35 are fixedly connected to the opposite sides of the four adjacent left and right limiting blocks 34, and the opposite ends of the four adjacent left and right springs 35 are fixedly connected to the sides of the inner walls of the four adjacent left and right positioning frames 32 that are close to each other.

[0039] The elastic force of spring 35 acts as a buffer to fix roller 26, preventing the fabric from being crushed.

[0040] like Figure 3 As shown, the pressing assembly 5 includes a mounting frame 51. The lower end of the mounting frame 51 is fixedly connected to the upper rear part of the base 1. A pressing machine body 52 is fixedly installed on the top of the mounting frame 51. A pressing plate 53 is fixedly installed on the bottom of the pressing machine body 52. ​​The pressing plate 53 is located in the middle of the moving frame 21.

[0041] The pressing body 52 is existing technology, capable of driving the pressing plate 53 downward to contact the fabric. The pressing body 52 is the power source for the entire pressing action. The pressing body 52 typically contains a hydraulic system with a drive mechanism that generates downward pressure. When pressing the bag is required, the pressing body 52 converts the power into downward movement of the pressing plate 53 through its internal drive mechanism, allowing the pressing plate 53 to apply pressure to the bag material below it, thereby achieving the pressing function.

[0042] The working principle of this utility model is as follows: In use, the fabric is laid flat on the worktable 4. The motor 29 is started according to its size. The output of the motor 29 drives the bidirectional lead screw 28 to rotate. Two sliders 210, through threaded connection with the bidirectional lead screw 28, drive the two front sliding plates 24 to move closer or further apart. The four sliding plates 24 move synchronously due to the connection of the two rollers 26, allowing the two rollers 26 to fix fabrics of different sizes. Subsequently, four hydraulic rods 23 are activated. When the four hydraulic rods 23 drive the moving frame 21 downwards, causing the four rollers 26 to contact the fabric on the surface of the worktable 4, the four rotating plates 25 drive the four rollers 26 to rotate, thereby causing the four adjusting rods 31 to rotate. The four adjusting rods 31 drive the four limiting blocks 34 to slide within the corresponding positioning frames 32. The springs 35, when under force, act as a buffer, ensuring that the rollers 26 apply uniform and moderate pressure to the fabric. After the fabric is fixed, the pressing machine body 52 (existing technology) drives the pressing plate 53 to move downwards and contact the fabric. Because the fabric pressing process in bag production involves pressing a piece or a whole piece of fabric together, it is necessary to cut this piece of fabric in subsequent processing to obtain the pressed area.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
