Description

Technical Field

[0001] The utility model belongs to the technical field of sheet production and winding, in particular to an automatic winding edge trimming device. Background Art

[0002] In the sheet production process, the winder's function is to collect the sheets neatly and uniformly into coils. However, due to uncontrollable factors (such as the winding rollers not being aligned, the machines not being aligned, and rough roller surfaces), the sheets may deviate during the winding process. Manual edge trimming relies on individual proficiency, and new operators are often unskilled and prone to sheet breakage, resulting in waste and loss. Utility Model Content

[0003] The purpose of the embodiment of the utility model is to provide an automatic edge trimming device for winding, which can accurately trim the edge by controlling the cylinder to prevent the sheet from breaking due to excessive cutting.

[0004] The utility model embodiment is achieved as follows:

[0005] An automatic trimming device for winding, comprising: a blade, a rotary cylinder, a double-axis cylinder, an air pressure regulating valve, a pneumatic mechanical valve manual switch 1, a pneumatic mechanical valve manual switch 2, a three-way switch and an air source regulating valve;

[0006] The air source regulating valve is connected to an external air source, and the air source regulating valve is connected to the pneumatic mechanical valve manual switch 1 and the pneumatic mechanical valve manual switch 2 through a three-way connection respectively. The pneumatic mechanical valve manual switch 1 is connected to the rotary cylinder through the air pressure regulating valve, and the pneumatic mechanical valve manual switch 2 is connected to the dual-axis cylinder. The blade is arranged as a whole on the rotary cylinder and rotates with the rotary cylinder. The bottom end of the blade abuts against the dual-axis cylinder to limit the blade.

[0007] Among them, the manual switch of the pneumatic mechanical valve is connected to the rotary cylinder through the air pressure regulating valve of the two-way air path.

[0008] Among them, the pneumatic mechanical valve manual switch 2 is connected to the double-axis cylinder through two air paths.

[0009] In order to avoid the production personnel failing to control the cutting amount during manual trimming operations, which may lead to sheet breakage and waste, the embodiment of the utility model utilizes a rotary cylinder to simulate the manual operation of the cutter to cut into the sheet, and utilizes a dual-axis cylinder to control the cutter braking and retracting action, thereby improving the control aspect. The cylinder can accurately control the cutting amount to prevent the sheet from breaking due to excessive cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a control principle diagram of the automatic edge trimming device for winding of the utility model. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] The following describes the specific implementation of the present invention in detail with reference to specific embodiments:

[0013] like Figure 1 As shown, an automatic trimming device for winding includes: a blade, a rotary cylinder, a double-axis cylinder, an air pressure regulating valve, a pneumatic mechanical valve manual switch 1, a pneumatic mechanical valve manual switch 2, a three-way valve and an air source regulating valve;

[0014] The air source regulating valve is connected to an external air source, and the air source regulating valve is connected to the pneumatic mechanical valve manual switch 1 and the pneumatic mechanical valve manual switch 2 through a three-way connection respectively. The pneumatic mechanical valve manual switch 1 is connected to the rotary cylinder through the air pressure regulating valve, and the pneumatic mechanical valve manual switch 2 is connected to the dual-axis cylinder. The blade is arranged as a whole on the rotary cylinder and rotates with the rotary cylinder. The bottom end of the blade abuts against the dual-axis cylinder to limit the blade.

[0015] In the figure, the manual switch of the pneumatic mechanical valve is connected to the rotary cylinder through the air pressure regulating valve of the two-way air circuit.

[0016] In the figure, the manual switch 2 of the pneumatic mechanical valve is connected to the dual-axis cylinder through two air paths.

[0017] Due to production needs, an automatic trimming device was installed on both sides of the winder. Position the device appropriately. Turn pneumatic valve switch 1 to position NO1. Air flows through the pressure regulating valve to the rotary cylinder, causing the blades to begin rotating counterclockwise. Turn pneumatic valve switch 2 to position NO1, causing air to flow to the dual-axis cylinders, which begin to retract. The stopper mechanism activates the blades, which now rotate 90°. Turn pneumatic valve switch 2 further to position NO2, causing air to flow to the dual-axis cylinders, which begin to extend. The stopper mechanism then becomes inoperative, causing the blades to continue rotating counterclockwise until they reach the limit position on the rotary cylinder, resulting in a 180° rotation. Position the automatic trimming device away from the sheet material. Turn pneumatic valve switch 1 to position NO2, causing air to flow through the pressure regulating valve to the rotary cylinder, causing the blades to begin rotating clockwise, returning from 180° to their initial 0° position. Turn the knobs on pneumatic mechanical valve manual switches 1 and 2 to OFF to deactivate the automatic trimming device. The air pressure regulating valve controls the air pressure, thereby controlling the rotation speed of the rotary cylinder blade, while the air source regulating valve regulates and monitors the total air pressure. The rotary cylinder adjusts the blade's rotation angle, and the dual-axis cylinder provides a limit function, allowing the blade's cutting depth and angle to be controlled, eliminating the arbitrariness of manual cutting and ensuring high-quality trimming.

[0018] In the embodiment of the present invention, the function of the automatic trimming machine is to trim the sheet in the direction of the deviated sheet, so that the force area of ​​the subsequent sheet becomes smaller, the sheet moves in the opposite direction, and the sheet returns to the center position. The automatic trimming device is not affected by the proficiency of the personnel skills, thereby reducing the loss in this area.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
