Description

Technical Field

[0001] The invention belongs to the technical field related to bags, and specifically refers to a cutting device for bag production. Background Art

[0002] Before producing bags, the material rolls need to be cut. When cutting, it is necessary to equip the corresponding cutting dies according to the design style of the bag, such as size, structure, internal compartments, zippers, buckles and other details, for use in cutting. A bag must require multiple cutting dies. The cutting machine applies pressure to the cutting dies through the punch to cut the material rolls into fabrics of different sizes and shapes, which are then sewn by the sewing equipment.

[0003] Due to the different sizes of fabrics, the length of some cutting dies is quite different from that of regular cutting dies. The punch of the cutting machine cannot cover the longer cutting dies at one time. During the first punching, one end of the cutting die often lifts up, making it impossible to completely punch out the fabric. Therefore, it is necessary to pull out the fabric and perform the second punching with the cutting die, which is very inconvenient.

[0004] At the same time, after the punch is pressed down to cut, the die cutter needs to be taken out and positioned at the next cutting position before the next cutting operation can be performed. This operation method has two defects. First, frequent positioning of the die cutter has a great impact on the operation efficiency; second, the same die cutter can only be repeatedly operated during the operation. Due to the limitation of the shape of some die cutters, the utilization rate of the fabric may be insufficient, and the residual gap between the die cutters is large, resulting in low utilization rate of the fabric. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a cutting device for bag production, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a cutting device for bag production, which includes a punching table, the middle part of which is a cavity, and a knife die is installed in the cavity for punching and cutting cloth.

[0007] Furthermore, a conveying roller assembly is horizontally passed through the punching table cavity, and the conveying roller assembly is used to convey the cloth, move the cloth to the punching position in the punching table, and convey the cut cloth to the receiving end. The type of the conveying roller can be adaptively adjusted according to the existing working conditions.

[0008] Furthermore, a feeding roller is provided at the end of the conveying roller assembly, one end of which is connected to a feeding motor, the feeding motor drives the feeding roller to rotate, and the feeding roller can vibrate the cloth; Furthermore, in order to improve the separation effect of the fabric after cutting, a roller brush array is provided on the unloading roller, and the unloading roller drives the roller brush to rotate back and forth and exerts downward pressure on the fabric.

[0009] Furthermore, a material box is provided below the unloading roller for recycling the cut fabrics, and the number and size of the material boxes are set according to the number and size of the cutting dies installed during the current punching and cutting operation.

[0010] Furthermore, a control box is provided on the side wall of the punching table for controlling the feeding, punching, loading and unloading actions during the punching operation.

[0011] Furthermore, a punching head is vertically slidable on the upper end of the punching table, and a punching cylinder is provided on the upper wall of the punching table. The extending rod of the punching cylinder passes through the punching table and is connected to the punching head. When the punching cylinder is telescopically moved, it can drive the punching head to move up and down, thereby cutting the cloth.

[0012] Furthermore, a self-separating knife die set is provided in the cavity of the punching table for sliding up and down. The self-separating knife die set is arranged below the punching head. When the punching head moves downward under the action of the punching cylinder, the self-separating knife die set is driven to move toward the cloth, thereby punching and cutting the cloth.

[0013] Furthermore, in order to simplify the operation steps, the cutting die embedded in the cloth can automatically separate from the cloth to the initial state without moving the cutting die a second time, the self-separating cutting die group includes a slide, a spring, a flange plate and a cutting die disc, the slide is symmetrically arranged at the bottom of the punching table cavity, the flange plate slides symmetrically on the side wall of the punching table cavity, the spring is connected between the slide and the flange plate, the cutting die disc is fixed between the two groups of flange plates, and a variety of different types of cutting dies can be fixed in the cutting die disc, when the cutting die disc is subjected to pressure, the cutting die disc drives the flange plate to compress the spring and move downward, when the cutting die disc is no longer subjected to pressure, the spring pushes the flange plate upward and restores the cutting die disc to its initial position; Furthermore, in order to facilitate the replacement of the cutting die on the cutting die disc, the slide can slide horizontally along the punching table cavity, so that the slide drives the upper cutting die disc to move outside the punching table cavity. In order to facilitate the movement of the slide, a handle is provided at the side end of the slide; Furthermore, in order to protect the die cutter disc and prevent the spring from being compressed to the limit and damaged when the stamping cylinder extends abnormally, an anti-collision plate is provided at the lower end of the flange plate. When the anti-collision plate contacts the slide, the flange plate stops moving and the die cutter disc no longer moves down.

[0014] Furthermore, the array inside the cutting die plate is provided with cutting die grooves, and the side frames of the cutting die grooves can slide, thereby changing the width of the cutting die grooves to meet the installation requirements of cutting dies of different widths. The cutting die grooves can combine and configure different types of cutting dies; Furthermore, a fixing rod is provided in the cutting die groove, and the fixing rod can slide following the change of the width of the cutting die groove. A fastening nut is provided at the end of the fixing rod. After sliding, the fixing rod is locked in a fixed position in the cutting die groove by the fastening nut. The fixing rod can fix the angle of the cutting die.

[0015] Furthermore, the punching head includes a longitudinal pressing plate, which is arranged on the telescopic rod of the punching cylinder. The longitudinal pressing plate moves up and down under the action of the punching cylinder, and the die plate is arranged below the longitudinal pressing plate; Furthermore, the lower end array of the longitudinal pressing plate is provided with a transverse pressing plate, and the number of the transverse pressing plates is set according to the number of the cutting dies; Furthermore, in order to cover a longer-sized cutting die at one time and avoid one end of the cutting die from tilting during the stamping process, the transverse pressing plate is provided with spaced-apart slitting heads that can be slidably adjusted to different positions of the transverse pressing plate.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The punching head can cover the longer size of the die, and evenly distribute the cutting heads to the front, middle and back three points of the die, so that the die is more evenly stressed. The cutting operation can be completed in one punching, and the die head will not be lifted, which improves the operation efficiency. 2. The self-separating knife die set can combine different types of knife dies to reduce the gap between knife dies, improve the utilization rate of fabrics and reduce waste; 3. The self-separating knife die set can automatically separate from the fabric after punching, without taking it out, thus improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] like Figure 1 As shown, the present invention provides a cutting device for bag production, comprising a punching table 1, the middle part of the punching table 1 is a cavity, and a cutting die is installed in the cavity for punching and cutting cloth.

[0023] A conveying roller assembly 2 runs horizontally through the cavity of the punching table 1. The conveying roller assembly 2 is used to convey the cloth, move the cloth to the punching position in the punching table 1, and convey the cut cloth to the receiving end. The type of the conveying roller can be adaptively adjusted according to the existing working conditions.

[0024] A feed roller 4 is provided at the end of the conveying roller assembly 2, and one end of the feed roller 4 is connected to a feed motor 5. The feed motor 5 drives the feed roller 4 to rotate, and the feed roller 4 can vibrate the cloth to facilitate the separation of the cut cloth from the raw material roll.

[0025] In order to improve the separation effect of the cut fabric, a roller brush 41 is arranged on the unloading roller 4. The unloading roller 4 drives the roller brush 41 to reciprocate and exert downward pressure on the fabric to separate the fabric from the original fabric without damaging the fabric.

[0026] A material box 6 is provided below the unloading roller 4 for recovering the cut fabrics. The number and size of the material boxes 6 are set according to the number and size of the cutting dies installed when the punching station 1 is currently operating.

[0027] A control box 7 is provided on the side wall of the punching table 1 for controlling the feeding, punching, unloading and discharging actions during the punching operation.

[0028] Combination Figure 2-Figure 4 As shown, a punching head 8 is vertically slidable in the punching table 1, and a punching cylinder 3 is provided on the upper wall of the punching table 1. The extending rod of the punching cylinder 3 passes through the punching table 1 and is connected to the punching head 8. When the punching cylinder 3 moves in a telescopic manner, it can drive the punching head 8 to move up and down, thereby cutting the cloth.

[0029] A self-separating knife die set 9 is provided in the cavity of the punching table 1 and slides up and down. The self-separating knife die set 9 is arranged below the punching head 8. When the punching head 8 moves downward under the action of the punching cylinder 3, the self-separating knife die set 9 will be driven to move toward the cloth, thereby punching and cutting the cloth.

[0030] In order to simplify the operation steps, the cutting die embedded in the cloth can automatically separate from the cloth to the initial state without moving the cutting die a second time. The self-separating cutting die group 9 includes a slide 10, a spring 11, a flange plate 12 and a cutting die disc 13. The slide 10 is symmetrically arranged at the bottom of the cavity of the punching table 1, and the flange plate 12 slides symmetrically on the side wall of the cavity of the punching table 1. The spring 11 is connected between the slide 10 and the flange plate 12, and the cutting die disc 13 is fixed between the two groups of flange plates 12. A variety of different types of cutting dies can be fixed in the cutting die disc 13. When the cutting die disc 13 is subjected to pressure, the cutting die disc 13 drives the flange plate 12 to compress the spring 11 and move downward. When the cutting die disc 13 is no longer subjected to pressure, the spring 11 pushes the flange plate 12 upward and restores the cutting die disc 13 to its initial position.

[0031] In order to facilitate the replacement of the cutting die on the cutting die disc 13, the slide 10 can slide horizontally along the cavity of the punching table 1, so that the slide 10 drives the upper cutting die disc 13 to move outside the cavity of the punching table 1. In order to facilitate the movement of the slide 10, a handle 15 is provided on the side end of the slide 10.

[0032] In order to protect the die cutter disc 13 and prevent the spring 11 from being compressed to the limit and damaged when the stamping cylinder 3 extends abnormally, an anti-collision plate 14 is provided at the lower end of the flange plate 12. When the anti-collision plate 14 contacts the slide 10, the flange plate 12 stops moving and the die cutter disc 13 no longer moves down.

[0033] like Figure 5As shown, the array inside the cutting die plate 13 is provided with a cutting die groove 16, and the side frame of the cutting die groove 16 can slide (the specific structure is not shown in the drawings), so as to change the width of the cutting die groove 16 to adapt to the installation requirements of cutting dies of different widths. The cutting die groove 16 can combine and configure different types of cutting dies. By changing the angle between each cutting die and configuring different cutting dies, the gap between the cutting dies can be reduced, thereby improving the utilization rate of the cloth and reducing waste.

[0034] A fixing rod 17 is provided in the cutting die groove 16. The fixing rod 17 can slide along with the width change of the cutting die groove 16. A fastening nut 18 is provided at the end of the fixing rod 17. After sliding, the fixing rod 17 is locked in a fixed position in the cutting die groove 16 by the fastening nut 18. The fixing rod 17 can fix the angle of the cutting die. During installation, the side of the cutting die needs to be provided with corresponding earrings (not shown in the drawings), and the angle of the earrings can penetrate into the fixing rod 17. There are threads on the fixing rod 17. After penetration, the cutting die can be fixed by fixing it with a nut.

[0035] like Figure 6 As shown, the punching head 8 includes a longitudinal pressing plate 19 , which is arranged on the telescopic rod of the punching cylinder 3 . The longitudinal pressing plate 19 moves up and down under the action of the punching cylinder 3 .

[0036] A transverse pressing plate 20 is arranged in an array at the lower end of the longitudinal pressing plate 19 , and the number of the transverse pressing plate 20 is set according to the number of the cutting dies.

[0037] In order to cover a longer size of cutting die at one time and prevent one end of the cutting die from tilting during the stamping process, a slitting press head 21 is slidingly provided on the transverse pressing plate 20 with intervals. The slitting press head 21 can be slidably adjusted to different positions of the transverse pressing plate 20 to adapt to cutting dies of different lengths, so that the front, middle and rear points of the cutting die are all subjected to pressure, so that the cutting die is evenly stressed and one end will not tilt.

[0038] During the specific work, the appropriate cutting die is selected according to the width of the cloth and the style of the bag to be processed. The number of cutting dies and the appearance of the cutting dies should be adapted to the cutting die plate 13 so that the gap between each group of cutting dies is small, the cloth can be fully cut, and the output of waste is reduced.

[0039] After selecting the cutting die, pull out the slide 10 through the handle 15 to move the cutting die plate 13 to the outside of the punching table 1, and then adjust the width of the cutting die groove 16 so that the width of each cutting die groove 16 is adapted to the cutting die to be installed. At the same time, adjust the position of the fixing rod 17 so that the position of the fixing rod 17 in each cutting die groove 16 is adapted to the earring on the cutting die to be installed, and then lock the fixing rod 17 by tightening the nut 18.

[0040] Then, the earrings on the cutting die are passed through the fixing rod 17, and nuts are added from the fixing rod 17 to fix the cutting die. After all the cutting dies are fixed, the clearances between the cutting dies are optimally matched.

[0041] When adjusting the cutting die plate 13, it is also necessary to adjust the position of the slitting head 21 according to the size of the cutting die, and slide each slitting head 21 so that the slitting head 21 on each horizontal pressing plate 20 is evenly distributed to the front, middle and back points of the cutting die.

[0042] Then the slide 10 is flushed and pushed into the punching table 1, the pneumatic conveying roller assembly 2, when the cloth moves to the lower end of the self-separating knife die group 9, the punching cylinder 3 extends downward, and drives the longitudinal pressing plate 19 to move downward through the telescopic rod, and the longitudinal pressing plate 19 drives the slitting head 21 to move downward through the transverse pressing plate 20, and the slitting head 21 drives the knife die on the knife die disk 13 to move downward, so that the knife die punches the cloth, and the contour of the punched cloth is the same as the contour of each knife die.

[0043] After the punching is completed, the punching cylinder 3 retracts, the die plate 13 and the die are no longer under pressure, and under the action of the spring 11, the flange plate 12 drives the die plate 13 to move upward, so that the die is automatically separated from the cloth.

[0044] The conveying roller assembly 2 continues to convey the cloth to the rear end. When the cloth moves to the unloading roller 4, the unloading roller 4 rotates back and forth under the action of the unloading motor 5, and the roller brush 41 continuously impacts the cloth to separate the cut cloth from the raw material. The separated cloth falls into the material box 6 below, thereby completing the cloth cutting operation.

[0045] Repeat the above steps later.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
