Description

Technical Field

[0001] The utility model relates to the technical field of feeding components, in particular to a feeding structure of a cutting machine. Background Art

[0002] As is known to all, in the process of making bags, it is often necessary to cut and trim some leather, cloth, film, etc., so a cutting machine is often used. The cutting machine needs to be fed or loaded during use. For example, the prior art CN212316529U discloses an auxiliary feeding device for a cutting machine, including a frame and a cutting machine body located on the frame. A feeding conveyor is provided on the feeding side of the cutting machine body. The feeding conveyor includes an active roller and a driven roller. A conveyor belt capable of transporting materials is wound around the active roller and the driven roller. Through the cooperation of the feeding conveyor and the rotating roller, the step-by-step feeding of the material is realized, so that the material is transported progressively for the same distance each time, thereby improving the cutting accuracy of the material.

[0003] However, the existing cutting machines lack good transmission buffering performance during the feeding and transmission process. The cloth used in bag making is often pulled too hard due to the excessively fast material transmission speed, which makes the quality of subsequent cutting unable to be guaranteed. In view of this, the utility model provides a feeding structure for a cutting machine. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a feeding structure for a cutting machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A feeding structure of a cutting machine comprises a cutting machine body, a feeding conveyor frame arranged on the right side of the cutting machine body, and a receiving frame arranged on the left side of the cutting machine body, on which a winding roller is rotatably mounted; a driving roller is rotatably mounted on the right end of the feeding conveyor frame, a feeding motor is fixedly mounted on the rear side of the feeding conveyor frame, and the output end of the feeding motor is fixedly connected to the driving roller; a driven roller is rotatably mounted on the left end of the feeding conveyor frame, and a conveyor belt for conveying bag fabrics is transmission-connected between the driving roller and the driven roller;

[0007] Two support frames are fixedly installed at the right end of the bottom of the loading conveyor frame, a vertical slot is provided on the right side of the support frame, a vertical block is slidably installed in the vertical slot, a rotating bracket is fixedly installed on the right side of the vertical block, and a feeding roller for feeding the bag fabric is also rotatably installed on the rotating bracket;

[0008] A guide slide bar is fixedly installed in the vertical groove, and the vertical block is movably mounted on the guide slide bar, and a first spring mounted on the guide slide bar is fixedly connected between the vertical block and the top inner wall of the vertical groove; a movable ring is also movably mounted on the guide slide bar located below the vertical block, and a second spring mounted on the guide slide bar is fixedly connected between the movable ring and the vertical block.

[0009] By adopting the above technical solution, both ends of the movable ring are rotatably connected with inclined rotating connecting rods, sliding grooves are provided on the inner walls on both sides of the vertical groove, sliding blocks are slidably installed in the sliding grooves, and a third spring is fixedly connected between the sliding block and the bottom inner wall of the sliding groove.

[0010] By adopting the above technical solution, the two rotating connecting rods are in an "eight"-shaped structure as a whole, and the top end of the rotating connecting rod is rotatably connected to the movable ring through a rotating pin.

[0011] By adopting the above technical solution, the vertical block is provided with a sliding hole, and the vertical block is slidably sleeved on the guide slide rod along the vertical direction through the sliding hole.

[0012] By adopting the above technical solution, sliders are provided on both sides of the vertical block, sliding grooves are provided on both inner walls of the vertical groove, and the sliders are slidably installed in the sliding grooves along the vertical direction.

[0013] By adopting the above technical solution, a material receiving motor is also installed on the front side of the material receiving rack, and the output end of the material receiving motor is fixedly connected to the front end of the winding roller.

[0014] By adopting the above structure, the utility model has the following beneficial effects:

[0015] In the utility model, when the feeding and conveying speed is too fast and the bag fabric is pulled too hard, the bag fabric on the unloading roller will move upward as a whole to buffer. When the unloading roller buffers upward, the vertical block is driven to move upward in the vertical groove by the rotating bracket, and the first spring is compressed. At the same time, the vertical block moves upward and stretches the second spring. In this way, the deformation of the first spring and the second spring can greatly consume a part of the excessive conveying pulling force on the bag fabric during the conveying process.

[0016] At the same time, when the second spring is stretched, it also drives the movable ring to move upward, and drives the sliding block to move upward by rotating the connecting rod, thereby stretching the third spring. In this way, the deformation of the third spring can further offset a part of the excessive transmission pulling force.

[0017] Finally, the entire cutting machine can have good buffering performance during the material feeding and conveying process; avoiding the disadvantage that the cloth used for bag making is often pulled too hard due to the excessively fast material conveying speed during the material feeding and conveying process of the existing cutting machine, thereby making the quality of the cut cloth unable to be guaranteed, thereby greatly meeting the existing usage needs.

[0025] Two support frames 4 are fixedly installed at the right end of the bottom of the feeding conveyor frame 2. A vertical groove 401 is provided on the right side of the support frame 4. A vertical block 5 is slidably installed in the vertical groove 401. A rotating bracket 6 is fixedly installed on the right side of the vertical block 5. A feeding roller 7 for feeding the bag fabric 8 is also rotatably installed on the rotating bracket 6.

[0026] A guide slide bar 408 is fixedly installed in the vertical groove 401, and the vertical block 5 is movably mounted on the guide slide bar 408, and a first spring 402 mounted on the guide slide bar 408 is fixedly connected between the vertical block 5 and the top inner wall of the vertical groove 401; a movable ring 404 is also movably mounted on the guide slide bar 408 located below the vertical block 5, and a second spring 403 mounted on the guide slide bar 408 is fixedly connected between the movable ring 404 and the vertical block 5.

[0027] In this example, both ends of the movable ring 404 are rotatably connected with an inclined rotating connecting rod 405, and sliding grooves 409 are provided on the inner walls on both sides of the vertical groove 401. A sliding block 406 is slidably installed in the sliding groove 409, and a third spring 407 is fixedly connected between the sliding block 406 and the bottom inner wall of the sliding groove 409.

[0028] In this example, the two rotating connecting rods 405 are overall in an "eight"-shaped structure, and the top end of the rotating connecting rod 405 is rotatably connected to the movable ring 404 through a rotating pin; a sliding hole 501 is provided on the vertical block 5, and the vertical block 5 is slidably mounted on the guide slide rod 408 along the vertical direction through the sliding hole 501.

[0029] Among them, sliders are provided on both sides of the vertical block 5, and slide grooves are provided on the inner walls on both sides of the vertical groove 401, and the sliders are slidably installed in the slide grooves along the vertical direction; a material receiving motor is also installed on the front side of the material receiving rack 3, and the output end of the material receiving motor is fixedly connected to the front end of the winding roller 301.

[0030] like Figure 1-4The feeding structure of the cutting machine shown in the figure, when cutting the cloth used for making bags, a part of the bag cloth 8 is pulled out from the unwinding roller 7 and first laid flat on the conveyor belt 203 between the active roller 202 and the driven roller 204, and the active roller 202 is driven by the feeding motor 201 to rotate, and the active roller 202 drives the conveyor belt 203 to move and transfer the bag cloth 8 on the conveyor belt 203 to the lower side of the cutting machine body 1, and then the cutting machine body 1 is used to cut the bag cloth 8, and after the cutting is completed, the feeding motor 201 continues to The bag fabric 8 is continuously fed from the feeding roller 7 during the feeding process of the bag fabric 8.

At the same time, the vertical block 5 moves upward and stretches the second spring 403. In this way, the deformation of the first spring 402 and the second spring 403 can greatly consume a part of the excessive transmission pulling force on the bag fabric 8 during the transmission process; at the same time, when the second spring 403 is stretched, it also drives the movable ring 405 to move upward, and drives the sliding block 406 to move upward by rotating the connecting rod 405, thereby stretching the third spring 407. In this way, the deformation of the third spring 407 can further offset a part of the excessive transmission pulling force, so that the entire cutting machine has good buffering performance during the feeding and transmission process, avoiding the existing cutting machine during the feeding and transmission process, often due to the excessively fast transmission speed of the material, resulting in the excessive pulling force of the fabric used in the bag making, and then the quality of the cut fabric cannot be guaranteed, thereby greatly meeting the existing use needs.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
