Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to an anti - adhesion structure for paper of a jump - knife cutting machine. Background Art

[0002] As an indispensable high - efficiency cutting device in modern manufacturing, the jump - knife cutting machine occupies an important position in the processing fields of paper, film, fabric and even more extensive materials by virtue of its unique jump - knife design. This cutting machine combines a precise mechanical structure with an advanced control system to achieve high - speed and accurate cutting of materials, greatly improving production efficiency and product quality.

[0003] Existing cutting machines, especially when dealing with papers with glue or sticky coatings, often face a significant problem: after cutting, the blade is prone to adhering to the gum residues on the paper. These gum residues may stem from the sticky coating of the paper itself, the use of glue in the printing process, or special treatments on the paper surface. During the cutting process, the contact and friction between the blade and the paper cause these gums to be adsorbed onto the blade surface, forming a difficult - to - remove adhesion layer.

[0004] Therefore, aiming at the problem of the above - mentioned gum residues adhering to the blade surface, an anti - adhesion structure for paper of a jump - knife cutting machine can be designed to prevent the paper from adhering to the blade surface by cleaning the sundries adhered to the blade surface during cutting. Content of the Utility Model

[0005] In order to overcome the problem of paper adhering to the blade surface.

[0006] The technical solution of the utility model is: an anti - adhesion structure for paper of a jump - knife cutting machine, including a workbench, and also including a guide rail. First support plates are installed at the upper ends of the left and right sides of the workbench. A machine case is fixedly connected to the upper ends of the first support plates. A telescopic cylinder is installed at the upper end of the machine case. A tool holder is installed at the lower end of the machine case. A blade is fixedly connected to the lower end of the tool holder. First fixing blocks are fixedly connected to the front and rear sides of the lower end of the tool holder. Anti - adhesion clamping blocks are connected to the lower ends of the first fixing blocks through springs. Second fixing blocks are fixedly connected to both sides of the front end of the anti - adhesion clamping blocks. The second fixing blocks are connected to an opening fixing block through second springs. A slide rail is fixedly connected to the rear end of the opening fixing block. Small motors are fixedly connected to the ends of the second fixing blocks far away from the anti - adhesion clamping blocks. Drive shafts are fixedly connected to the output ends of the small motors. A belt is installed on the surface of the drive shaft. One end of an anti - adhesion scraping plate is fixedly connected to the surface of the belt. The other end of the anti - adhesion scraping plate is fixedly connected to a sliding rod;

[0007] Both the left and right ends of the guide rail are fixedly connected with second support plates. A slider is installed at the lower end of the guide rail. A support rod is fixedly connected to the lower end of the slider. A motor is fixedly connected to the front end face of the support rod. The output end of the motor is fixedly connected with a gear.

A blower box is fixedly connected to the surface of the left end of the second support plate. A first air guide box is installed on the front end face of the blower box.

[0008] Preferably, a connecting rod is fixedly connected to the upper end of the anti-adhesion clamping block. A spring is sleeved outside the connecting rod. A sliding hole is formed inside the first fixing block. The connecting rod passes through the sliding hole and is slidably connected to the first fixing block. A nut is threadedly connected to the upper end of the connecting rod, which facilitates the up and down movement of the anti-adhesion clamping block and its reset after the blade is lifted, and is convenient for cleaning the adhered objects.

[0009] As a preference, the bottom surfaces of the anti-adhesion scraping plate and the anti-adhesion clamping block are mutually adapted. The sliding rod is slidably connected to the sliding rail, which is beneficial to cleaning the garbage adhered to the surface.

[0010] As a preference, a convex rod is fixedly connected to the rear end of the second fixing block. A second nut is fixedly connected to the rear end of the convex rod. The convex rod is sleeved with a second spring. The sliding connection between the convex rod and the opening fixing block makes the cleaning of the anti-adhesion clamping block cleaner.

[0014] The beneficial effects of the present utility model:

[0015] 1. After the cutting operation is completed, when the blade is lifted, the two anti-adhesion clamping blocks configured on both sides thereof use the elastic force characteristics of the spring to automatically move closer to the blade, forming an effective cleaning action. This action can effectively squeeze and remove debris such as paper scraps and gum residues on the blade, thereby significantly reducing or avoiding the paper adhesion problem during subsequent cutting, improving the cutting quality and efficiency. Considering that during long-term operation or when processing highly sticky paper, paper scraps, gum, and other debris may accumulate at the bottom of the anti-adhesion clamping blocks, affecting the cleaning effect of the clamping blocks and the overall performance of the equipment, this device starts a small motor, uses the power output by the motor to drive the transmission shaft to rotate, and then drives the belt to rotate in a cycle. An anti-adhesion scraper is fixed on the belt. As the belt rotates, its edge part can closely fit the bottom of the anti-adhesion clamping block and scrape off the gum and garbage accumulated here, keeping the bottom of the anti-adhesion clamping block clean and ensuring the smooth progress of subsequent cutting operations.

[0016] 2. For the paper anti-adhesion structure of this jump knife cutting machine, during use, start the motor to drive the slider to move to the right along the guide rail, so that the dust collection box slides to the right. At the same time, start the blower box to generate suction force, and make the suction port generate suction force through the air duct, which is convenient for cleaning the dust on the tabletop. After the cleaning is completed, the dust collection box can be pulled out from the clamping seat, which is convenient for cleaning the inhaled garbage. BRIEF DESCRIPTION OF THE DRAWINGS
