Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to a fabric cutting machine that facilitates material feeding. Background Technology

[0002] The fabric cutting machine uses a crank-slider mechanism. The crank wheel drives the slider to move up and down through a connecting rod. The blade is fixed on the slider to achieve vertical movement. The machine chassis is equipped with rollers, which can move the machine horizontally. This allows the blade to form a combined vertical reciprocating motion and a horizontal advancing motion to cut the fabric. After the machine is started, the operator pushes the machine, which moves along the cutting pattern on the cutting table by relying on four small rollers mounted under the base. The vertical reciprocating motion and horizontal advancing motion of the blade combine to cut the fabric. The presser foot on the machine presses down on the fabric by its own weight to prevent the fabric from shaking due to the reciprocating cutting of the straight blade.

[0003] In the current fabric cutting industry, many cutting machines lack effective guiding devices for the fabric during the feeding process, which easily leads to deviation. This causes the fabric to not be accurately aligned with the cutting tools when entering the cutting area, affecting the cutting accuracy. Insufficient tension during feeding can also cause wrinkles, affecting the cutting quality. Utility Model Content

[0004] The purpose of this invention is to provide a fabric cutting machine that facilitates material feeding, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric cutting machine that facilitates material feeding, comprising a processing box.

[0008] And cutting components disposed on the left and right sides of the processing box; characterized in that:

[0009] The cutting assembly includes a feeding mechanism located on the left side of the processing box and auxiliary mechanisms located on the left and right sides of the processing box. The feeding mechanism includes a guide roller, side plates, and a hydraulic cylinder. The two side plates are arranged in parallel, with one end fixedly installed on the left side wall of the processing box. A rotating rod is rotatably mounted on the inner side of the two side plates via bearings. A guide roller is fixedly installed on the outer side wall of the rotating rod. The hydraulic cylinder is fixedly installed on the left side of the processing box. An adjusting plate is fixedly mounted on the hydraulic cylinder via a hydraulic rod at its output end. One end of a connecting rod is hinged to both ends of the adjusting plate. A displacement block is hinged to the other end of the connecting rod. A limit baffle is fixedly installed on the top of the displacement block. The inner wall of the limit baffle is slidably connected to the outer side wall of the guide roller.

[0010] Preferably, the outer wall diameter of the guide roller matches the inner wall diameter of the limiting baffle.

[0011] Preferably, there are two limiting baffles, and the two limiting baffles are of equal shape and size.

[0012] Preferably, the auxiliary mechanism includes a feeding auxiliary component disposed on the left side of the processing box and a receiving auxiliary component disposed on the right side of the processing box. The feeding auxiliary component includes a mounting roller, an auxiliary roller, and an electric push rod. A pad is fixedly connected to the outer wall of the side plate. An electric push rod is fixedly installed on the top of the pad. A moving block is fixedly installed on the top of the electric push rod. The auxiliary roller is rotatably mounted on the moving block via a bearing. A vertical plate is slidably mounted on the moving block. The bottom of the vertical plate is fixedly connected to the top of the side plate.

[0013] Preferably, there are two upright plates, and the inner walls of the two upright plates are provided with rectangular grooves that are slidably connected to the movable block.

[0014] Preferably, there are two electric actuators, which are arranged opposite each other at both ends of the auxiliary roller.

[0015] Preferably, the two ends of the mounting roller are rotatably connected to the inner wall of the side plate via bearings, and the mounting roller is located to the left of the auxiliary roller.

[0016] Preferably, the receiving auxiliary component includes a take-up roller, a motor, and two oppositely arranged mounting plates. The mounting plates are fixedly installed on the right side wall of the processing box. A motor is fixedly installed on the outer side of one of the mounting plates. The motor passes through the inner wall of the mounting plate via a rotating shaft at its output end and has a take-up roller fixedly installed thereon.

[0017] Preferably, there are four support legs, all of which are of the same shape and size. The four support legs are fixedly installed at the four bottom corners of the processing box, and the support legs can support the position of the entire device.

[0018] This invention provides a fabric cutting machine that facilitates material feeding. It offers the following advantages:

[0019] (1) In this utility model, the operator passes one end of the fabric through the top of the auxiliary roller, then through the bottom of the mounting roller, then contacts the top of the guide roller, then through the bottom of the cutting machine body, and finally connects to the side wall of the take-up roller. When the operator feeds the fabric, the position of the limiting baffle can be adjusted according to the width of the fabric. The operator directly opens the hydraulic cylinder, and the hydraulic cylinder drives the position of the adjusting plate to move through the hydraulic rod at the output end. Under the action of the connecting rod, the adjusting plate drives the position of the limiting baffle to move, causing the limiting baffle to slide on the side wall of the guide roller. This allows the limiting baffle to limit and guide the position of the fabric, preventing the fabric from deviating during cutting and feeding. This solves the problem in the existing fabric cutting industry where many cutting machines lack an effective guiding device during the feeding process, which easily causes the fabric to deviate, resulting in the fabric not being accurately aligned with the cutting tools when entering the cutting area, thus affecting the cutting accuracy.

[0020] (2) The electric push rod can be opened by the operator. The electric push rod can adjust the position of the moving block. The moving block can further adjust the position of the auxiliary roller. When the position of the auxiliary roller is moved, the tension of the fabric will be effectively adjusted to prevent wrinkles from appearing when the fabric is fed, which will affect the cutting.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the fabric cutting machine with easy feeding provided by this utility model is as follows: Figures 1 to 4 As shown: A fabric cutting machine for easy feeding, including a processing box 1,

[0028] The support legs 2 are fixedly installed at the bottom of the processing box 1. There are four support legs 2, and the four support legs 2 are all the same in shape and size. The four support legs 2 are fixedly installed at the four corners of the bottom of the processing box 1, and the position of the whole device can be supported by the support legs 2.

[0029] The cutting machine body 3 is installed on top of the processing box 1;

[0030] And the cutting components 4 are set on the left and right sides of the processing box 1;

[0031] The cutting assembly 4 includes a feeding mechanism 41 located on the left side of the processing box 1 and auxiliary mechanisms 42 located on the left and right sides of the processing box 1.

[0032] The feeding mechanism 41 includes a guide roller 416, side plates 418, and a hydraulic cylinder 411. The two side plates 418 are arranged in parallel, and one end of one of them is fixedly installed on the left side wall of the processing box 1. A rotating rod 417 is rotatably installed on the inner side of the two side plates 418 through bearings. The guide roller 416 is fixedly installed on the outer side wall of the rotating rod 417. The hydraulic cylinder 411 is fixedly installed on the left side of the processing box 1. An adjusting plate 412 is fixedly installed on the hydraulic cylinder 411 through the hydraulic rod at the output end. One end of a connecting rod 413 is hinged to both ends of the adjusting plate 412. A displacement block 414 is hinged to the other end of the connecting rod 413. A limit baffle 415 is fixedly installed on the top of the displacement block 414. The inner wall of the limiting baffle 415 is slidably connected to the outer wall of the guide roller 416. The diameter of the outer wall of the guide roller 416 matches the diameter of the inner wall of the limiting baffle 415. There are two limiting baffles 415, and the two limiting baffles 415 are of equal shape and size and are arranged opposite to each other on the outer wall of the guide roller 416.

[0033] In the specific implementation process, when the operator uses the device, the support leg 2 at the bottom of the device first supports the overall position of the device. When the operator feeds the fabric, the position of the limiting baffle 415 can be adjusted according to the width of the fabric. The operator directly opens the hydraulic cylinder 411. The hydraulic cylinder 411 drives the position of the adjusting plate 412 to move through the hydraulic rod at the output end. Under the action of the connecting rod 413, the adjusting plate 412 drives the position of the limiting baffle 415 to move, causing the limiting baffle 415 to slide on the side wall of the guide roller 416. This allows the limiting baffle 415 to limit and guide the position of the fabric, preventing the fabric from shifting during cutting and feeding due to the lack of effective limiting on both sides.

[0034] Example 2: Based on Example 1, a preferred embodiment of the fabric cutting machine for easy feeding provided by this utility model is as follows: Figures 1 to 4 As shown: The auxiliary mechanism 42 includes a feeding auxiliary component disposed on the left side of the processing box 1 and a receiving auxiliary component disposed on the right side of the processing box 1. The feeding auxiliary component includes a mounting roller 424, an auxiliary roller 425 and an electric push rod 428. A pad 427 is fixedly connected to the outer wall of the side plate 418. The electric push rod 428 is fixedly installed on the top of the pad 427. A moving block 426 is fixedly installed on the top of the electric push rod 428. The moving block 426 rotates to mount the auxiliary roller 425 through a bearing. A vertical plate 429 is slidably mounted on the moving block 426. The bottom of the vertical plate 429 is fixedly connected to the top of the side plate 418.

[0035] In this embodiment, there are two upright plates 429, and the inner walls of the two upright plates 429 are provided with rectangular grooves that are slidably connected to the side walls of the movable block 426. There are two electric actuators 428, which are arranged opposite to each other at both ends of the auxiliary roller 425. The two ends of the mounting roller 424 are rotatably connected to the inner walls of the side plate 418 through bearings, and the mounting roller 424 is located on the left side of the auxiliary roller 425.

[0036] The material taking-up auxiliary assembly includes a take-up roller 422, a motor 423, and two oppositely arranged mounting plates 421. The mounting plates 421 are fixedly installed on the right side wall of the processing box 1. The motor 423 is fixedly installed on the outer side of one of the mounting plates 421. The motor 423 passes through the inner wall of the mounting plate 421 via a rotating shaft at its output end and is fixedly installed with the take-up roller 422. The other end of the take-up roller 422 is rotatably connected to the inner wall of the other mounting plate 421 via a bearing.

[0037] In practice, the operator passes one end of the fabric through the top of the auxiliary roller 425, then through the bottom of the mounting roller 424, and then to the top of the guide roller 416. The fabric then passes through the bottom of the cutting machine body 3 and is finally wound up by the take-up roller 422. The operator can activate the electric push rod 428, which adjusts the position of the moving block 426. The moving block 426 further adjusts the position of the auxiliary roller 425. When the auxiliary roller 425 moves, it squeezes the lower side of the fabric, effectively adjusting the fabric tension and preventing wrinkles during feeding, thus facilitating better operation of the device.

[0038] (The cutting machine body 3 is existing publicly available technology, therefore its internal structure has not been fully described).

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
