Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a novel silk fabric cutting device. Background Technology

[0002] New silk is a new type of synthetic fiber fabric. Due to its use of new production processes and raw materials, it has the following characteristics: New silk has a light and soft feel and good breathability, making it comfortable to wear. It is not prone to static electricity, has good wrinkle resistance, and is easy to care for. New silk has high tensile strength and abrasion resistance, good tensile performance, strong scratch resistance, and is not easily deformed.

[0003] In the existing technology, when cutting new silk fabrics with cutting blades, the surface of the new silk fabric is smooth and the tensile strength is weak. The cutting blades directly contact the fabric, which can easily cause the fabric to shift and lead to deviations in the cutting size. At the same time, the direct impact of the cutting blades may also cause the fabric edges to fray and the fibers to break, damaging the appearance and physical properties of the fabric. Therefore, we propose a new silk fabric cutting device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel silk fabric cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel silk fabric cutting device includes a housing, an arc-shaped cutting seat fixedly connected inside the housing, a guide plate fixedly connected to the outer wall of the housing, a cylinder fixedly connected inside the housing, a U-shaped frame fixedly connected to the bottom of the cylinder's output end, two cylinders fixedly connected inside the housing, a knife holder fixedly connected to the bottom of the U-shaped frame, a cutting blade fixedly connected to the bottom of the knife holder, an L-shaped plate fixedly connected to the outer wall of the knife holder, a hollow rubber seat fixedly fitted to the bottom of the L-shaped plate, and a conveying assembly inside the housing.

[0007] Preferably, the conveying assembly includes a guide plate, and four conveying rubber rollers and two guide rollers are rotatably connected inside the housing. The guide plate is located between the two guide rollers, and both ends of the guide plate are fixedly connected to the inner wall of the housing. The conveying assembly drives the new silk fabric body to move.

[0008] Preferably, the outer wall of the housing is rotatably connected to an unwinding roller, and the outer wall of the unwinding roller is fitted with a novel silk fabric body, which supports the rolled novel silk fabric body.

[0009] Preferably, both ends of the conveying rubber roller and the guide roller are fixedly fitted with roller bearings, the outer ring of the roller bearings is fixedly connected to the inner wall of the machine housing, and the roller bearings assist the conveying rubber roller and the guide roller to rotate stably.

[0010] Preferably, the outer wall of the U-shaped frame has two sliding grooves, the inner walls of the two sliding grooves are slidably connected to the outer walls of the two cylinders respectively, and the two sliding grooves cooperate with the two cylinders to assist the U-shaped frame in moving up and down.

[0011] Preferably, the cutting blade is located above the arc-shaped cutting seat.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses an arc-shaped cutting seat to stably support the new silk fabric body from below. The cylinder-driven U-shaped frame, through the sliding limit of the cylinder and the slide groove, ensures that the cutting blade always moves vertically and aligns with the arc-shaped cutting seat. Combined with the compression limit of the rubber seat, it can effectively prevent the new silk fabric body from shifting during cutting, preventing edge fuzzing or fiber breakage. Both the conveying rubber roller and the rubber seat are made of rubber, which reduces scratch damage to the new silk fabric body through elastic contact. The rubber seat has the functions of pre-compression limit, cutting buffer and automatic reset, and works with the guide plate to guide the cut fabric in time to avoid accumulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-5 As shown, a novel silk fabric cutting device is disclosed, comprising a housing 1, with an unwinding roller 2 rotatably connected to the outer wall of the housing 1. A novel silk fabric body is sleeved on the outer wall of the unwinding roller 2, and the unwinding roller 2 can smoothly release the wound novel silk fabric body to realize continuous fabric feeding.

[0023] An arc-shaped cutting seat 6 is fixedly connected inside the chassis 1. The arc-shaped cutting seat 6 adopts an arc-shaped structure design and cooperates with the cutting blade 13. During the cutting process, it can provide stable support for the new silk fabric body from below, and prevent the fabric from denting or shifting due to uneven force at the moment of cutting.

[0024] A guide plate 7 is fixedly connected to the outer wall of the casing 1. The guide plate 7 is located downstream of the cutting area and can guide and convey the cut fabric.

[0025] A cylinder 8 is fixedly connected inside the casing 1. A U-shaped frame 9 is fixedly connected to the bottom of the output end of the cylinder 8. Two cylinders 10 are fixedly connected inside the casing 1. Two sliding grooves 11 are opened on the outer wall of the U-shaped frame 9. The inner walls of the two sliding grooves 11 are slidably connected to the outer walls of the two cylinders 10 respectively. When the U-shaped frame 9 moves up and down with the cylinder 8, the movement direction of the U-shaped frame 9 is constrained by the sliding grooves 11 along the sliding trajectory of the cylinders 10, ensuring that the U-shaped frame 9 always moves in the vertical direction, and avoiding the offset of the tool holder 12 and the cutting blade 13 due to the deviation of the power output of the cylinder 8.

[0026] The bottom of the U-shaped frame 9 is fixedly connected to a knife holder 12, and the bottom of the knife holder 12 is fixedly connected to a cutting blade 13. The cutting blade 13 can quickly cut the new silk fabric body through its sharp blade design. The cutting blade 13 is located above the arc-shaped cutting seat 6.

[0027] An L-shaped plate 14 is fixedly connected to the outer wall of the blade holder 12. A hollow rubber seat 15 is fixedly fitted at the bottom of the L-shaped plate 14. The rubber seat 15 is long and has good elasticity and cushioning performance. During the cutting action, because its position is lower than the cutting blade 13, it can preferentially squeeze the top of the new silk fabric body, form a stable limit on it, and prevent the fabric from shifting at the moment of cutting.

[0028] The machine housing 1 is equipped with a conveying assembly, which includes a guide plate 5. Four conveying rubber rollers 3 and two guide rollers 4 are rotatably connected inside the machine housing 1. The conveying rubber rollers 3 are made of rubber and have good elasticity and friction. When they come into contact with the new silk fabric body, they can provide sufficient driving force to drive the fabric conveying, while avoiding damage to the fabric surface due to rigid contact, and reducing problems such as fabric pilling and scratching.

[0029] The guide roller 4 can guide the new silk fabric body during conveying, ensuring that the fabric always moves along the preset path. Both ends of the conveying rubber roller 3 and the guide roller 4 are fixedly fitted with roller bearings, and the outer ring of the roller bearings is fixedly connected to the inner wall of the machine box 1.

[0030] The guide plate 5 is located between the two guide rollers 4. Both ends of the guide plate 5 are fixedly connected to the inner wall of the machine box 1. The guide plate 5 provides auxiliary support to the fabric being conveyed through the planar support structure, so as to prevent the fabric from sagging due to its own weight or from developing local wrinkles during the conveying process.

[0031] Working principle: In use, each of the four conveying rubber rollers 3 is equipped with an existing drive device (such as a stepper motor or servo motor) at one end. The drive device drives the rollers to rotate. The four conveying rubber rollers 3 are arranged in pairs, with adjacent conveying rubber rollers 3 rotating in opposite directions. The new silk fabric body is rolled up on the unwinding roller 2, with one end passing between the two sets of conveying rubber rollers 3 and located at the top of the two guide rollers 4 and the guide plate 5. As the drive device drives the two sets of conveying rubber rollers 3 to rotate, the two sets of conveying rubber rollers 3 rotate and transport the new silk fabric body to the position of the cutting blade 13, with one end extending onto the guide plate 7. The cylinder 8 rotates, causing the U-shaped frame 9 to move downwards. The downward movement of the U-shaped frame 9 causes the knife holder 12 to move downwards. The downward movement of the knife holder 12 causes the cutting blade 13 and the L-shaped plate 14 to move downwards, thereby causing the rubber seat 15 to move downwards. The position of the rubber seat 15 is lower than that of the cutting blade 13, and it is squeezed to the top of the new silk fabric body first, limiting it. At this time, the two sets of conveying rubber rollers 3 stop rotating. The cutting blade 13 continues to move downwards and cooperates with the arc-shaped cutting seat 6 to cut the new silk fabric body. The rubber seat 15 deforms. When the cylinder 8 drives the U-shaped frame 9 to reset upwards, the rubber seat 15 resets itself through its own rubber material.

[0032] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the cylinder 8 and the drive equipment to facilitate the control of the overall operation.

The machinery, parts and equipment adopt conventional models in the prior art.
