Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a feeding rack for an automatic cutting machine. Background Art

[0002] Cutting machine, also known as cutting bed, molding machine, die-cutting machine, cutting machine, etc., is a processing equipment widely used in industrial production. It uses different transmission methods and control mechanisms to achieve punching and cutting of materials.

[0003] Hydraulic transmission cutting machine is a more common type in modern times. It uses hydraulic oil as the working medium, generates huge pressure through the hydraulic pump, and then controls the cutting angle and accuracy through on-off or logic hydraulic control elements. Finally, with the help of the oil cylinder or motor, the pressure energy of the hydraulic oil is converted into mechanical energy, thereby driving the blade on the load to perform linear or rotary motion to complete the cutting work.

[0004] Cutting machines play a vital role in garment factories. They are an indispensable part of the garment production process. They are mainly used to cut flexible materials such as cloth, leather, and artificial leather according to preset patterns, providing accurate cut pieces for subsequent sewing, processing and other processes.

[0005] However, the traditional cutting machine feeder is fixed and cannot be adjusted in length according to the length of the material. This results in a long working time of the feeding mechanism when cutting some small areas of cloth, affecting the cutting efficiency. In addition, the feeder whose width cannot be adjusted is not convenient for the staff to load and unload the material. Therefore, an automatic cutting machine feeder is proposed to address the above problems. Utility Model Content

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-5 As shown, an automatic cutting machine feed frame includes a body 1, a feed plate 3 is slidably connected to the body 1, and a hydraulic head 2 is slidably connected to the surface of the body 1;

[0032] A feeding bracket 4 is fixedly connected to one side of the body 1. The feeding bracket 4 is "L"-shaped. There are two feeding brackets 4, and a pair of feeding brackets 4 are symmetrically distributed around the central axis of the feeding plate 3.

[0033] A guide rail groove 11 is provided on the surface of the feeding bracket 4, and a plurality of equidistant blocks 14 are slidably connected in the guide rail groove 11;

[0034] Each equidistant block 14 is provided with a cross mechanism on its surface for equidistant sliding of the equidistant block 14 , and a rotating wheel 7 is provided on the surface of the equidistant block 14 ;

[0035] The equidistant block 14 is provided with a positioning mechanism for fixing the equidistant block 14;

[0036] The positioning mechanism includes a slider 10, which is fixed on an equidistant block 14 farthest from the body 1. A top shaft 8 is slidably connected to the slider 10. The surface of the top shaft 8 is connected to the rotating shaft 5 through a thread. The end of the top shaft 8 is fixedly connected to an anti-slip pad.

[0037] During operation, the feeding bracket 4 is set up on one side of the body 1, and then the feeding plate 3 is placed above the feeder. The fabric on the surface of the feeding plate 3 is cut by the hydraulic head 2. When fabrics of different widths need to be cut, the rotating shaft 5 is rotated first. By rotating the rotating shaft 5, the top shafts 8 on both sides are driven to retract inward, so that the top shafts 8 release the positioning of the slider 10. At this time, the rotating shaft 5 can be pulled so that the top shaft 8 drives the slider 10 to slide on the surface of the guide shaft 12. At the same time, the slider 10 drives the equidistant blocks 14 to slide on the surface of the guide shaft 12, and at the same time, the cross mechanism is cooperated to make the distance between each equidistant block 14 equal. The distance is increased or decreased, and the feeding bracket 4 can cooperate to support wider or narrower fabrics, which is more convenient for staff to load and unload materials and effectively improve cutting efficiency. After the equidistant block 14 is moved to the appropriate distance, the rotating shaft 5 is rotated so that the threads in the rotating shaft 5 drive the top shafts 8 on both sides to slide away from each other, so that the two top shafts 8 are pressed against the side walls of the guide groove 11, and the equidistant block 14 is fixed to avoid sliding arbitrarily with the feeding plate 3. The rotating wheel 7 can reduce the friction between the feeding plate 3 and the feeding bracket 4, effectively reduce wear and tear, and increase the service life of the feeding bracket 4 and the feeding plate 3.

[0038] The equidistant block 14 closest to the body 1 is fixedly connected to the guide rail groove 11, and the positioning mechanism is fixed to the equidistant block 14 farthest from the body 1. The guide rail groove 11 is fixedly connected to the guide shaft 12. All slidable equidistant blocks 14 are slidably connected to the surface of the guide shaft 12 through the through hole 15. The cross mechanism includes a number of main rods 17 and auxiliary rods 19. The main rods 17 and auxiliary rods 19 are rotatably connected by hinges. A slide groove 18 is provided on the surface of each equidistant block 14. The main rod 17 and auxiliary rod 19 are rotatably connected end to end, and the positions where the main rod 17 and auxiliary rod 19 are connected end to end are movably connected in the slide groove 18 through a limit shaft 20.

[0039] During operation, when the equidistant block 14 farthest from the main body 1 slides, because the equidistant block 14 on the side closest to the main body 1 is in a fixed state, when the equidistant block 14 farthest from the main body 1 slides, it will drive the main rod 17 and the auxiliary rod 19 in the cross mechanism on its surface to slide in the slide groove 18, and a chain reaction will occur at the same time, driving all the cross mechanisms to rotate at the same time, thereby making all the equidistant blocks 14 slide synchronously, realizing equidistant sliding between the equidistant blocks 14, so that the equidistant blocks 14 drive the runner 7 to be evenly distributed under the feed plate 3, avoiding uneven force on the feed plate 3, causing the feed plate 3 to bend, affecting the cutting of the cutting machine, and the equidistant blocks 14 can be guided by the guide shaft 12 to limit the sliding direction of the equidistant blocks 14 to avoid offset.

[0040] An oil storage chamber 21 is provided in the slider 10, and an oil filling hole is provided on the surface of the oil storage chamber 21. A fixing frame 29 is fixedly connected to the oil storage chamber 21, and a sliding rod 28 is slidably connected to the surface of the fixing frame 29 through a spring. One end of the sliding rod 28 is fixedly connected to a plug block 30, and the other end is fixedly connected to a secondary magnetic block 27. The surface of the top shaft 8 is fixedly connected to the main magnetic block 26. A lower oil hole 31 is opened on the oil storage chamber 21, and an oil distribution ring 25 is opened in the slider 10. The lower oil hole 31 is communicated with the oil distribution ring 25. A sponge ring 22 is fixedly connected to the through hole 15, and the sponge ring 22 passes through the oil distribution ring 25 and is connected. An oil guide groove 16 is provided on the surface of the equidistant block 14, and an oil storage groove 24 is provided on the surface of the guide rail groove 11;

[0041] Finally, excess oil will flow through the oil guide groove 16 into the oil storage tank 24 on the surface of the guide rail groove 11 for storage, so that it can be recycled and reused by the staff.
