Description

Technical Field

[0001] This utility model relates to the technical field of fabric processing equipment, and more specifically, it relates to a trimming device for processing polyester fabric. Background Technology

[0002] Polyester grey fabric is a fabric made from polyester fiber as the main raw material through weaving process without dyeing and finishing. During the production and processing of polyester grey fabric, there may be problems such as rough edges and unevenness at the edges, which will affect subsequent processing steps and the quality of finished products. Therefore, it is necessary to use trimming devices to trim the edges of the grey fabric to make them neat and accurate in size.

[0003] Existing trimming devices for polyester fabric processing typically guide the trimmed waste into a waste bin when handling waste. However, due to a lack of effective sorting, there are many gaps between the waste materials after they are introduced into the waste bin. This prevents the waste collection bin from fully utilizing its internal space to accommodate more waste, resulting in low utilization of the waste collection space. This not only increases the frequency of waste cleaning and production costs but also affects production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a trimming device for processing polyester fabric. Through the setting of a guide unit and a winding unit, the drive mechanism drives the guide ring to move back and forth, uniformly covering the waste generated during trimming along the length of the roll. This fully utilizes the winding space of the roll, reducing the frequency of waste cleaning and lowering production costs compared to existing collection methods.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a trimming device for processing polyester fabric, comprising a machine body, a conveying roller for conveying fabric, a cutting assembly for cutting fabric, and a winding assembly for winding fabric. A recycling device for collecting waste material after cutting is provided on one side of the cutting assembly. The recycling device includes a support frame, a guiding unit, and a winding unit. The guiding unit includes a crossbar provided on the support frame. A sliding block is slidably sleeved on the crossbar. A guide ring for waste material to pass through is provided on the sliding block. A driving mechanism for driving the sliding block to slide back and forth is provided on the support frame.

[0006] The winding unit includes a first motor mounted on a support frame, a rotating frame mounted on the output shaft of the first motor, and second motors symmetrically mounted at both ends of the rotating frame. A shaft is mounted on the output shaft of the second motor, and the shaft is used to fix a roll for winding up waste material.

[0007] The present invention is further configured such that: the driving mechanism includes a reciprocating lead screw rotatably connected to a support frame, a third motor is provided on the support frame, and the output shaft of the third motor is fixedly connected to one end of the reciprocating lead screw.

[0008] The present invention is further configured such that the shaft is an air-expanding shaft structure.

[0009] The present invention is further configured such that: the recycling device also includes waste guide wheels symmetrically arranged on the machine body, and the two waste guide wheels are arranged between the cutting component and the guide ring.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. Through the set guide unit and winding unit, the drive mechanism drives the guide ring to move back and forth, so that the waste generated by trimming is evenly covered along the length of the roll, making full use of the winding space of the roll.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] Reference Figures 1-2 A trimming device for processing polyester fabric includes a machine body 1, a conveying roller 2 for conveying the fabric, a cutting component 3 for cutting the fabric, and a winding component for winding the fabric. A recycling device 4 for collecting waste material after cutting is provided on one side of the cutting component 3. The above are all mature existing technologies and will not be described in detail here.

[0021] The recycling device 4 includes a support frame 41, a guide unit 42, and a winding unit 43. The guide unit 42 includes a crossbar 411 fixed on the support frame 41. A sliding block 412 is slidably sleeved on the crossbar 411. A guide ring 413 for waste material to pass through is fixed on the sliding block 412. The support frame 41 is provided with a drive mechanism for driving the sliding block 412 to slide back and forth.

[0022] The winding unit 43 includes a first motor fixedly mounted on a support frame 41. A rotating frame 421 is fixedly mounted on the output shaft of the first motor. A second motor is symmetrically mounted on both ends of the rotating frame 421. A shaft body 422 is fixedly mounted on the output shaft of the second motor. The shaft body 422 is used to fix the roll 423 for winding up the waste material.

[0023] The driving mechanism includes a reciprocating screw 414 rotatably connected to a support frame 41. A third motor is fixedly mounted on the support frame 41. The output shaft of the third motor is fixedly connected to one end of the reciprocating screw 414. When it is necessary to drive the sliding block 412 to slide back and forth, the third motor is started. The output shaft of the third motor drives the reciprocating screw 414 to rotate. The sliding block 412 will move along the reciprocating screw 414 under the action of the thread. Since the sliding block 412 is slidably sleeved on the crossbar 411 and cooperates with the reciprocating screw 414, the rotation of the reciprocating screw 414 causes the sliding block 412 to reciprocate linearly along the crossbar 411, thereby ensuring that the guide ring 413 moves according to the predetermined trajectory and speed, and realizing the uniform guidance of waste material in the length direction of the drum 423.

[0024] The shaft 422 is an air-expanding shaft structure. When installing the drum 423, compressed air is filled into the air-expanding shaft, and the surface of the shaft 422 expands, thereby tightly fixing the drum 423. When it is necessary to remove the drum 423, the compressed air is released, the surface of the shaft 422 returns to its original shape, and the drum 423 can be easily removed, saving the waiting time when replacing the drum 423 and improving production efficiency.

[0025] The recycling device 4 also includes waste guide wheels 44 symmetrically rotated and mounted on the machine body 1. The two waste guide wheels 44 are located between the cutting assembly 3 and the guide ring 413. After the waste comes out of the conveying roller 2, it is first guided by the two waste guide wheels 44, and then passes through the guide ring 413 for subsequent winding operations. The waste guide wheels 44 can adjust the direction of the waste so that it can enter the guide ring 413 more smoothly.

[0026] Working principle: When using this trimming device, the waste edges cut by the cutting component 3 are first introduced into the recycling device 4 for orderly collection. Specifically, the waste material is passed through the guide ring 413, and then wound onto the drum 423 of the winding unit 43. The second motor in the winding unit 43 is started, and the second motor drives the shaft 422 on its output shaft to rotate. Since the drum 423 is fixedly sleeved on the shaft 422, it is driven to rotate, thereby realizing the winding of the waste material. During the winding process, the drive mechanism of the guide unit 42 is started at the same time. The drive mechanism drives the sliding block 412 to slide back and forth along the slide rod. The guide ring 413 moves accordingly, and the waste material is evenly covered along the length of the roll 423 as the guide ring 413 moves, avoiding excessive accumulation of waste material at a certain position on the roll 423. When the roll 423 is fully wound, the first motor in the winding unit 43 is started. The first motor drives the rotating frame 421 to rotate, so that the positions of the two rolls 423 at both ends of the rotating frame 421 are swapped, and the waste material can continue to be wound on the new roll 423. During the operation of the new roll 423, the operator can remove the fully wound roll 423 and replace it with a new roll 423 to ensure the continuity of waste material collection.

[0027] This invention, through the setting of the guide unit 42 and the winding unit 43, drives the guide ring 413 to move back and forth via the drive mechanism, so that the waste generated by trimming is evenly covered along the length of the roll 423, making full use of the winding space of the roll 423, reducing the frequency of waste cleaning, and lowering production costs; at the same time, the design of two rolls 423 with interchangeable positions allows the waste to be quickly transferred to the new roll 423 for continued winding after one roll 423 is full, improving the continuity of waste collection and thus improving production efficiency.

[0028] The first, second, and third motors of this invention are all electrically connected to the controller to achieve coordinated operation. The controller's control circuit can be easily programmed by those skilled in the art, and the power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
