Description

Technical Field

[0001] The invention relates to the technical field of cloth production and processing, and in particular to a bag fabric punching and cutting device and a use method thereof. Background Art

[0002] Fabric plays a significant role in decorative display and is often the main force that cannot be ignored in the entire sales space. A large amount of fabric is used for wall decoration, partitions, and background processing, which can also form a good commercial space display style. According to the raw materials, it can be divided into cotton, chemical fiber, linen, wool, silk, and blended fabrics;

[0003] Chinese patent CN113684669B proposes a cloth cutting device. In the initial state, the abutting convex part of the abutting roller rotates upward, the cloth to be cut is placed on the cutting table and the two sides of the cloth are respectively located under the abutting roller. The abutting roller is driven to rotate by rotating the rotating shaft so that the abutting convex part is pressed against the two sides of the cloth to be cut, thereby realizing the pressing and fixing of the cloth to be cut, thereby effectively reducing the possibility of the cloth being deviated during the cutting process, thereby improving the accuracy and aesthetics of cutting. By adjusting the length of the telescopic adjustment member, the angle of the connecting strip is adjusted. When the rotating shaft is fixed, the tip of the abutting block abuts against the upper surface of the cloth. By reducing the length of the telescopic adjustment member, the free end of the connecting strip is driven to rotate toward the direction close to the cloth, thereby making the tip of the abutting block penetrate into the cloth to be cut. At the same time, a pulling force is applied to the cloth to be cut, so that the cloth to be cut is in a stretched and flattened state, effectively reducing the possibility of the cloth being deviated during the cutting process.

[0004] However, I have discovered that the fixing mechanism in the above-mentioned device is rigidly connected to the cloth when it is in contact with the cloth. When cutting cloth of different thicknesses, it is necessary to constantly adjust the telescopic adjustment member so that the pressing block can be pressed against the cloth surface. However, constantly adjusting the telescopic adjustment member is too inconvenient. In addition, the fixing mechanism is provided on both sides of the device. When adjusting the cloth, the fixing mechanisms on both sides need to be adjusted at the same time before the cloth can be adjusted. However, if only one fixing mechanism is provided, the cloth cannot be made taut. Summary of the invention

DETAILED DESCRIPTION Embodiment 1

[0029] like Figure 1-3 As shown, a bag fabric punching and cutting device comprises a frame 1, on which a processing platform 11 for placing processed fabrics is provided, and on which a fixing device 2, a cutting device 3, a pushing device 4, and a tightening device 5 are provided from left to right, respectively. The cutting device 3 and the pushing device 4 are driven to move by a driving device respectively. When in use, the fabric is placed on the processing platform 11, the front end and the middle end of the fabric are fixed by the fixing device 2 and the pushing device 4, and the fabric is cut by the cutting device 3. When the fabric between the fixing device 2 and the cutting device 3 is cut, the fabric is pushed forward by the pushing device 4, and the pushed fabric is adsorbed and fixed by the tightening device 5, so that the fabric is flat and tight as a whole and will not be accumulated between the pushing device 4 and the tightening device 5.

[0030] Furthermore, the fixing device 2 includes a swing plate 21 and a stop plate 22, wherein the stop plate 22 is movably arranged in the swing plate 21, and the stop plate 22 protrudes from the lower end surface of the swing plate 21. The middle parts of both sides of the swing plate 21 are swingably arranged on the frame 1 through a rotating shaft 211, and a rocker 212 is also arranged on the upper parts of both sides of the swing plate 21, so that the swing plate 21 can be pushed to swing with the rotating shaft 211 as a fulcrum. When the fabric is fixed by the swing plate 21, the rocker 212 can be pushed downward, and the swing plate 21 can be driven to swing by the rocker 212 until the stop plate 22 is pressed against the surface of the fabric, thereby fixing one end of the fabric and as shown in FIG. Figure 2 , 3 As shown, the swing plate 21 is hollow inside, but solid near the axis of the rocker 212, so that the swing plate 21 is top-heavy, so that after the rocker 212 is gently pushed to break the balance of the swing plate 21, the upper part of the swing plate 21 moves downward with gravity, and the abutment plate 22 is pressed against the surface of the fabric;

[0031] In addition, the fixing device 2 further comprises a first slide groove 23 arranged on both sides of the frame body 1, the first slide groove 23 and the rotating shaft 211 are coaxially arranged and the first slide groove 23 coincides with the swing path of the rocker 212, the rocker 212 passes through the first slide groove 23, a second spring 231 is arranged in the first slide groove 23, and two ends of the second spring 231 respectively abut against the inner side of the first slide groove 23 and the outer side of the rocker 212, the purpose of providing the first slide groove 23 and the second spring 231 is to enable the user to more intuitively observe the swing arc and the swing angle of the swing plate 21, and the second spring 231 forms a soft connection and elastic support for the rocker 212 and the inner side of the first slide groove 23;

[0032] Furthermore, in order to enable the abutment plate 22 to fix fabrics of different heights and thicknesses, a soft connection is provided on the abutment plate 22. The inner lower part of the swing plate 21 has a cavity, and the abutment plate 22 is movably arranged in the cavity. The abutment plate 22 and the inner upper end surface of the cavity are supported by a plurality of first springs 221, so that a soft connection is formed for the abutment plate 22 by the plurality of first springs 221, so that the abutment plate 22 is supported by the first springs 221.

[0033] The swing plate 21 is bent. The purpose of such arrangement is that when the upper part of the swing plate 21 is perpendicular to the processing platform 11, the lower part of the swing plate 21 is inclined and does not contact the fabric. When the lower part of the swing plate 21 gradually tilts or is about to tilt, it will contact the fabric and break the balance of the swing plate 21, so that the heavier upper part of the swing plate 21 drives the swing plate 21 to swing as a whole, so that the contact plate 22 can be tightly contacted with the surface of the fabric. Embodiment 2

[0034] In this embodiment, the pushing device 4 includes a roller 41, a support plate 42, a motor 43, and a slider 44. The support plates 42 are arranged on both sides of the roller 41, and the motor 43 is installed on one of the support plates 42. The output shaft of the motor 43 passes through the support plate 42 and is connected to the axis of the roller 41. The two support plates 42 are respectively clamped on the frame 1 through the slider 44; the roller 41 protrudes from the lower end surface of the support plate 42, the roller 41 is against the fabric and the roller 41 rotates in the direction of fabric movement, so as to abut the fabric through the roller 41, and when the motor 43 drives the roller 41 to rotate in the opposite direction of the fixing device 2, that is, the fabric movement direction, the two ends of the fabric will be fixed and tightened by the fixing device 2 and the pushing device 4 respectively, so that the surface of the fabric remains taut and will not bend or folded, resulting in a decrease in accuracy when the cutting device 3 cuts the fabric, and as Figure 4As shown, there is a threaded hole on the slider 44, and the push device 4 is driven to move by a screw transmission mechanism. The screw in the screw transmission mechanism passes through the threaded hole and is threadedly connected to the slider 44, or the slider 44 can also be understood as a screw slider, that is, the movement of the slider 44 can be controlled by rotating the screw in the screw transmission mechanism, thereby driving the overall push device 4 to move. Embodiment 3

[0035] like Figure 5 , Figure 6 As shown, the tightening device 5 in this embodiment includes a mounting shell 51, negative pressure rollers 52 and 53. The mounting shell 51 is fixed on the frame 1, and the negative pressure roller 52 is rotatably mounted in the mounting shell 51. The negative pressure roller 53 is clamped on the side of the mounting shell 51. The mounting shell 51 has a second slide groove 511 on both sides, and the negative pressure roller 52 has a support shaft 521 passing through the second slide groove 511 on both sides. One of the support shafts 521 is connected to an external air pump through a connecting pipe 522 to exhaust air. The other supporting shaft 521 is connected to the output shaft of a driving motor. The upper end of the 532 has a plurality of rubber beads, and the mounting shell 51 has a corresponding clamping hole 514. When 53 is mounted on the side of the mounting shell 51, the rubber beads are embedded in the clamping hole 514. A guide plate 513 is also provided on the side of the mounting shell 51 away from 53. The guide plate 513 is arranged on the side of the mounting shell 51 away from the pushing device 4. The inner side of the guide plate 513 is against the outer side of the negative pressure roller 52, and The outer side of the guide plate 513 is curved. When the fabric between the fixing device 2 and the pushing device 4 is cut by the cutting device 3 and the fabric is pushed forward by the cutting device 3, the fabric can be manually passed under the negative pressure roller 52, and the negative pressure roller 52 is driven to rotate by the driving motor installed on the supporting shaft 521. At the same time, the air in the negative pressure roller 52 is evacuated through the air pump connected to the connecting pipe 522. As shown in the figure, the surface of the negative pressure roller 52 has a plurality of air holes. Therefore, when the negative pressure roller 52 is negative, the negative pressure roller 52 is evacuated. When pressure is applied, the air holes of the negative pressure roller 52 will absorb the fabrics. Since the negative pressure roller 52 is rotating, the fabrics are simultaneously lifted up during the rotation, thereby pushing the fabrics forward. Moreover, since the guide plate 513 is in contact with the surface of the negative pressure roller 52 and the surface of the guide plate 513 is curved, the fabrics moving upward can be effectively guided. Moreover, the guide plate 513 does not have an adsorption effect. When the fabrics move to the guide plate 513, they will fall into a pile due to their own gravity, making it easy for the operator to collect them.

[0036] In addition, the second slide groove 511 has a movable gap for the support shaft 521 to move up and down, and a third spring 512 is provided in the movable gap. The linkage rod of the support shaft 521 is respectively abutted against the inner upper end of the second slide groove 511 and the upper end of the support shaft 521. The purpose of such a setting is to form a soft connection with the support shaft 521 through the third spring 512, so that when fabrics of different thicknesses pass under the negative pressure roller 52, they can be abutted against by the negative pressure roller 52. Embodiment 4

[0037] This embodiment provides a method for using a bag fabric punching and cutting device, and the method includes the following steps:

[0038] S1: placing the fabric on the processing platform 11, allowing the fabric to pass through the fixing device 2, the cutting device 3, and the pushing device 4 in sequence, and the fixing device 2 and the pushing device 4 abut against the fabric;

[0039] S2: The fabric is pressed down and fixed by the fixing device 2, and the motor 43 is controlled to drive the roller 41 to rotate in the opposite direction, so that the roller 41 drives the fabric in contact with it to move forward during the rolling, so that the fabric passes through the fixing device 2 and the pushing device 4 to form a taut state;

[0040] S3: Cut the fixed fabric by the cutting device 3, and let the operator take the cut finished product;
