Description

Technical Field

[0001] The utility model relates to the technical field of emery cloth seaming machines, in particular to a guide device for emery cloth seaming machines. Background Art

[0002] In the textile and manufacturing industries, abrasive cloth is a common material widely used in various grinding and polishing operations. In the production process of abrasive cloth, a sewing machine is an indispensable equipment used to sew the two ends or the middle part of the abrasive cloth to form a continuous abrasive cloth roll or abrasive cloth sheet of a specific shape. However, due to its special material and characteristics, abrasive cloth often faces some technical challenges in the sewing process.

[0003] During sewing, the existing device clamps the emery cloth by means of structures such as a splint, but the sewing portion at the end of the emery cloth is not clamped. Since the emery cloth is relatively soft, the end of the emery cloth is easily deformed during the sewing process. Sewing after deformation will not only affect the appearance quality of the emery cloth, but more seriously, it may cause the position of the sewing line to shift, and even cause sewing failure.

[0004] Therefore, a kind of emery cloth seam machine guiding device is needed to overcome the generation of the above problems. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the utility model provides a guide device for an abrasive cloth seam end machine, which achieves the purpose of solving the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a guiding device for an abrasive cloth sewing machine, comprising a frame, a clamping assembly for clamping the abrasive cloth is arranged on the frame, a sewing machine body for sewing the abrasive cloth is arranged on the frame, a driving assembly for driving the sewing machine body to move is arranged on the frame, and a guide plate for guiding the sewing of the abrasive cloth is arranged on the clamping assembly; a through groove is opened on the guide plate, and a fixing assembly for fixing the end of the abrasive cloth is arranged on the guide plate, and the fixing assembly includes a pressure plate hingedly arranged on one side of the guide plate and a magnet fixedly connected to the guide plate.

[0007] As a further improvement of the above technical solution:

[0008] The clamping assembly comprises a lower clamping plate fixedly connected to the frame, an upper clamping plate arranged above the lower clamping plate through an electric push rod, and an anti-skid pad fixedly connected to the bottom of the upper clamping plate.

[0009] The upper clamping plate is provided with a pre-tightening component;

[0010] The pre-tightening assembly comprises an elastic member which is elastically and telescopically arranged inside the upper clamping plate, and a pressure roller which is rotatably arranged on the elastic member.

[0011] The elastic member comprises a fixed column fixedly connected to the interior of the upper clamping plate, and a movable column elastically slidably arranged inside the fixed column through a spring; and the pressure roller is rotatably arranged on the movable column.

[0012] The driving assembly comprises a slide bar fixedly connected to a frame, a screw rod rotatably arranged on the frame, and a slider threadedly connected to the outside of the screw rod and slidably arranged outside the slide bar; the main body of the seaming machine is arranged on the slider.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] In actual use, after moving the end of the abrasive cloth to the guide plate, rotate the pressure plate so that the pressure plate is fixed on the guide plate through magnet adsorption, so that the end of the abrasive cloth can be clamped by the pressure plate and the guide plate to complete the fixation of the end of the abrasive cloth. When sewing, the deformation of the abrasive cloth end can be prevented to affect the sewing effect. BRIEF DESCRIPTION OF THE DRAWINGS
