[0012] Preferably, the use method of the positioning and cutting device for the production of silica gel heating sheet comprises the following steps.

[0013] S1: first, wind the silica gel heating sheet to be cut on the winding machine, then stretch one end of the silica gel heating sheet and attach it to the conveying belt, when the conveying belt moves the silica gel heating sheet to the bottom of the cutting frame through the driving shaft, control the driving motor to work, thereby driving the driving member to rotate, the driving column drives the sliding member to slide up and down on the sliding column through the driving sliding groove, and then drives the cutting frame to reciprocatingly move up and down in the cutting box;

[0014] S2: when the cutting frame moves towards the silica gel heating sheet on the conveying belt, the cutting knife moves towards the silica gel heating sheet, when the cutting frame descends, the moving column is arranged to drive the cutting knife to slide in the horizontal moving groove along the direction in which the hook groove is formed, and the reset spring is arranged to return the cutting knife to the original position when the cutting knife moves away from the silica gel heating sheet, and the pressing members arranged on both sides of the cutting knife limit the silica gel heating sheet from above when the cutting knife cuts, and the extrusion spring is arranged to drive the pressing members on both sides to move in the opposite direction when the cutting knife moves upwards, thereby cleaning the surface of the cutting knife with the cleaning sponge;

[0016] S4: before the silica gel heating sheet is cut, the electric push rod is controlled to work, thereby driving the slope-shaped block to move in the adjusting box, thereby driving the control plate to move to the bottom of the T-shaped box along the direction of the limiting column and the limiting sleeve through the cooperation of the locking and the oblique through groove, thereby driving the T-shaped box and the adjusting frame to move along the slide column, and thereby adjusting the distance between the cutting knife and the conveying belt.

[0017] Compared with the prior art, the beneficial effects of the present application are:

[0018] In the present application, when the device is used, the staff first winds the silica gel heating sheet to be cut on the winding machine, then stretches one end of the silica gel heating sheet and attaches it to the conveying assembly, controls the driving cutting assembly to work, thereby driving the cutting knife to reciprocate on the surface of the conveying assembly, and when the cutting knife works, the conveying assembly is synchronously driven to work through the linkage device, thereby conveying the silica gel heating sheet to the driving cutting assembly, and when the silica gel heating sheet moves below the cutting knife, the silica gel heating sheet is synchronously cut. Since the power of the conveying assembly comes from the driving cutting assembly, the conveying distance of the silica gel heating sheet by the conveying assembly is consistent when the cutting knife moves to the conveying assembly each time, so that the length of the cut silica gel heating sheet is consistent, thereby improving the cutting precision. The spacing adjustment assembly can adjust the spacing between the cutting knife and the conveying belt before cutting, so that the cutting length can be accurately positioned. At the same time, during the cutting of the silica gel heating sheet by the cutting knife, the cutting limiting assembly is arranged, so that the cutting knife can move horizontally during cutting, better completing the cutting work of the silica gel heating sheet. When the cutting knife finishes cutting, the pressing and cleaning assembly is arranged on both sides of the cutting knife to fix the silica gel heating sheet from top to bottom, facilitating the cutting process, preventing the cutting knife from detaching and causing the silica gel heating sheet to deviate in position due to the stickiness of the surface of the silica gel heating sheet, and cleaning the surface of the cutting knife when it is detached to avoid the surface of the cutting knife being attached with glue, improve the cutting efficiency, and make the cutting process stable, thereby realizing accurate positioning during cutting and further limiting the silica gel heating sheet when the cutting knife is detached to avoid insufficient cutting precision and low cutting efficiency.

[0019] In the present application, first, the silica gel heating sheet to be cut is wound on the winding machine, then one end of the silica gel heating sheet is stretched out and attached to the conveying belt, when the conveying belt moves the silica gel heating sheet to the bottom of the cutting frame through the driving shaft, the driving motor is controlled to work, thereby driving the driving part to rotate, the driving column drives the sliding part to slide up and down on the sliding column through the driving sliding groove, thereby driving the cutting frame to reciprocate up and down in the cutting box, thereby facilitating uninterrupted cutting work of the silica gel heating sheet on the conveying belt, and improving the convenience during cutting.

[0020] When the cutting frame moves towards the silica gel heating sheet on the conveying belt, the cutting knife is driven to move towards the silica gel heating sheet. When the cutting frame is lowered, the moving column is arranged to drive the cutting knife to slide in the horizontal moving groove along the direction in which the hook groove is opened. Therefore, the cutting knife can complete the cutting action more quickly when cutting the silica gel heating sheet. When the cutting knife moves away from the silica gel heating sheet, the reset spring is arranged to quickly return the cutting knife to the original position and separate the cutting knife from the silica gel heating sheet by using the reaction force. Therefore, the cutting process is accelerated, and the cutting work on the silica gel heating sheet is better completed. When the cutting knife is cutting, the abutting members arranged on both sides of the cutting knife are used to limit the silica gel heating sheet from above, so that the cutting process is facilitated, and the possibility of position deviation of the silica gel heating sheet caused by the adhesion of the silica gel heating sheet is prevented. When the cutting knife is separated, the extrusion spring is arranged. Therefore, when the cutting knife moves upward, the abutting members on both sides move in the opposite direction, so that the surface of the cutting knife is cleaned by the cleaning sponge, thereby avoiding the adhesion of the cutting knife surface to the glue, improving the cutting efficiency, and making the cutting process stable.

[0021] In the present application, the cutting frame moves up and down in the cutting box, thereby driving the sliding members on both sides to move up and down in the T-shaped box. When one of the sliding members moves downward, the activation block moves up and down in the sliding rail, and the driving rod drives the rotating member in the synchronization box to swing up and down with the end of the driving rod away from the rotating member as the reference point. In the process of swinging of the rotating member, the crank connected with the center of the rotating member rotates around the center of the rotating shaft, thereby driving the rotating shaft to rotate. The first transmission member is arranged to drive the second transmission member to rotate synchronously under the action of the transmission belt, thereby driving the driving shaft to rotate and making the conveying belt work. Therefore, the silica gel heating sheet can be conveyed by the conveying belt synchronously when the cutting knife works, and the conveying distance of the conveying belt remains consistent when the cutting knife completes the cutting each time, so that the length of the silica gel heating sheet after each cutting is consistent, thereby improving the cutting precision.

[0022] In the present application, before the silica gel heating sheet is cut, the electric push rod is controlled to work, thereby driving the slope-shaped block to move in the adjustment box. The control plate is driven to move towards the bottom of the T-shaped box along the direction of the limiting column and the limiting sleeve under the cooperation of the locking and the oblique through groove, thereby driving the T-shaped box and the adjusting frame to move along the sliding column, so that the distance between the cutting knife and the conveying belt is adjusted, and the length of the cutting is accurately positioned, thereby controlling the length of the cut silica gel heating sheet.
