An edge trimming device for a jet loom

Abstract

This utility model relates to the field of fabric trimming technology and discloses a trimming device for an air-jet loom. It includes a mounting frame, with a cutting mechanism and a clamping mechanism fixedly mounted on the inner wall of the frame. The cutting mechanism includes a fixing frame, the side of which is fixedly connected to the inner wall of the mounting frame. A dual-axis motor is turned on, driving a first threaded rod to rotate, which in turn moves a first slider along the threaded rod. This, in turn, pushes a mounting component and a drive motor to move, thereby adjusting the position of the cutting disc. After adjustment, the dual-axis motor is turned off, and the drive motor is turned on, causing the cutting disc mounted on the end face of the drive motor's transmission rod to rotate. Simultaneously, a servo motor is turned on, further driving a second threaded rod to rotate. This second threaded rod, in turn, cooperates with a threaded sleeve to move a second slider along a guide rail, thereby causing the cutting disc to cut the fabric, completing the fabric cutting operation and improving cutting accuracy and efficiency.

Description

Technical Field

[0001] This utility model relates to the field of fabric trimming technology, specifically to a trimming device for an air-jet loom. Background Technology

[0002] Air-jet looms are widely used in factories due to their simple mechanical structure, high product quality, easy availability of working medium, and lack of pollution. However, the fabric produced by air-jet looms often has uneven edges and is prone to defects such as frayed edges, which usually require edge trimming.

[0003] During the fabric transport process, edge trimming devices are typically used to cut both sides of the fabric. Cutting is done with a cutting blade. However, due to the cutting force generated during the cutting process, the fabric is prone to wrinkles and deviations in the edge position, affecting the quality of the trimming. Traditional edge trimming devices require handheld fabric cutters to cut the fabric scraps, but manual cutting has low precision, and the fabric is prone to curling due to lack of clamping during cutting, which in turn affects the cutting quality.

[0004] Therefore, there is a need to provide a cutting device for air-jet looms. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for an air-jet loom to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for an air-jet loom, comprising a mounting frame, a cutting mechanism fixedly mounted on the inner wall of the mounting frame, and a clamping mechanism fixedly mounted on the inner wall of the mounting frame; the cutting mechanism comprises a fixing frame, the side of the fixing frame being fixedly connected to the inner wall of the mounting frame, a dual-axis motor fixedly mounted on the inner wall of the fixing frame, a first threaded rod fixedly mounted on the end face of the transmission rod of the dual-axis motor, the end face of the first threaded rod being fixedly connected to the inner wall of the mounting frame through a bearing seat, a first slider threadedly mounted on the side of the first threaded rod, a servo motor fixedly mounted on the side of the first slider, the transmission rod of the servo motor passing through the first slider and extending to the outside of the first slider, and a second threaded rod fixedly mounted on the end face of the transmission rod of the servo motor.

[0007] Preferably, a threaded sleeve is threadedly installed on the side of the second threaded rod, and a second slider is fixedly installed on the side of the threaded sleeve. A through hole is fixedly opened on the side of the second slider, and a guide rail is slidably installed on the inner wall of the through hole. The end face of the guide rail is fixedly connected to the side of the first slider.

[0008] Preferably, a fixing block is fixedly installed on the bottom end face of the second slider, a cylinder is fixedly installed on the side of the fixing block, an mounting component is fixedly installed on the end face of the cylinder push rod, a drive motor is fixedly installed on the side of the mounting component through a fixing plate, and a cutting disc is fixedly installed on the end face of the drive motor transmission rod.

[0009] Preferably, the clamping mechanism includes a mounting plate, the side of which is fixedly connected to the inner wall of the mounting frame, a lower clamping block is fixedly mounted on the top surface of the mounting plate, a lower rubber pad is fixedly mounted on the top surface of the lower clamping block, and a fixing member is fixedly mounted on the side of the lower clamping block.

[0010] Preferably, a servo motor is fixedly mounted on the side of the fixing member, an upper clamping block is engaged with the side of the lower clamping block, an upper rubber pad is fixedly mounted on the bottom end face of the upper clamping block, the bottom end face of the upper rubber pad corresponds to the top face of the lower rubber pad, and the side of the upper clamping block is fixedly connected to the end face of the servo motor output rod through a connecting rod.

[0011] Preferably, a support leg is fixedly installed on the side of the mounting frame, an anti-slip pad is fixedly installed on the bottom end face of the support leg, and a base plate is snapped onto the bottom end face of the mounting frame.

[0012] Preferably, a top plate is fixedly installed on the top surface of the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The edge-cutting device for this air-jet loom operates by turning on a dual-axis motor to rotate a first threaded rod, which in turn moves a first slider along the first threaded rod. This, in turn, pushes a mounting component and a drive motor to move via a cylinder, thereby adjusting the position of the cutting disc. After adjustment, the dual-axis motor is turned off, and the drive motor is turned on to rotate the cutting disc mounted on the end face of the drive motor transmission rod. Simultaneously, the servo motor is turned on to rotate, further rotating a second threaded rod. This second threaded rod, in turn, cooperates with a threaded sleeve to move a second slider along a guide rail, thereby driving the cutting disc to cut the fabric, completing the fabric cutting operation and improving cutting accuracy and efficiency.

[0014] 2) When using this jet loom edge trimming device, the servo motor is first rotated, which in turn drives the upper clamping block to deflect around the servo motor transmission rod. The upper clamping block is then placed on the lower rubber pad. The servo motor is then turned to deflect the upper clamping block, closing the upper and lower rubber pads and clamping the fabric. The fabric is then cut by the cutting mechanism. This enhances the friction during clamping, thereby improving the clamping stability, cutting accuracy, and cutting efficiency.
