Description

Technical Field

[0001] This utility model relates to the field of paper product manufacturing and slitting technology, specifically to a slitting device for paper product manufacturing. Background Technology

[0002] Slitting equipment for paper manufacturing is a specialized device used to cut paper or paperboard according to specific requirements. It plays a key role in the paper product manufacturing process, cutting large-sized paper raw materials into smaller-sized sheets that meet the needs of subsequent processing, thus ensuring the dimensional accuracy and quality of the paper.

[0003] When existing slitting equipment performs downward cutting, the paper itself has a certain layer thickness, which can easily cause the other end to curl up, resulting in the paper cutting surface being tilted, affecting the accuracy of slitting. In addition, when the slitting blade is lifted, it does not have an anti-fall limit structure, which can easily lead to safety hazards.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a slitting device for paper product manufacturing, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a slitting device for paper product manufacturing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slitting device for paper product manufacturing, comprising a top pressure plate, a crossbar, and a connecting plate. The top pressure plate has a top arc plate along its upper edge and a pad is installed at the bottom of the top pressure plate. A second lifting rod assembly is installed on both sides of the surface of the pad, and a top frame is installed on the top of the second lifting rod assembly. A first lifting rod assembly is symmetrically installed on the outer side of the top frame, and a clamping plate is connected to the bottom of the first lifting rod assembly. Slitting blades are installed on the inner sides of the two clamping plates.

[0007] The outer walls of the top pressure plate are connected to side plates, and a connecting plate is provided at the horizontal end of the top pressure plate away from the first lifting rod assembly.

[0008] The connecting plate has fitting grooves embedded in both sides, and a horizontal plate is provided at the top of the fitting groove. The bottom of the horizontal plate is connected to a rear upright plate via a connecting rod. Spring compression rods are symmetrically embedded inside the rear upright plate, and the bottom of the spring compression rods is connected to a rear pressure plate.

[0009] The inner wall of the side plate has a horizontal bar, and a fitting plate is sleeved on the outer side of the horizontal bar. A V-shaped scraper is installed on the horizontal side of the fitting plate. The V-shaped scraper and the cutting blade are matched in size. A first horizontal push rod is provided at the horizontal connection end of the fitting plate and the side plate.

[0010] A detection sensor is provided on the top of the interlocking plate, and a sensor sensing contact is provided on the outer wall of the card plate.

[0011] Furthermore, the rear upright plate is elastically connected to the rear pressure plate via a spring compression rod, and the rear upright plate is horizontally positioned.

[0012] Furthermore, an electrical connection is formed between the detection sensor and the sensor sensing contact.

[0013] Furthermore, a second horizontal push rod is provided at the vertical end connection between the horizontal plate and the connecting plate, and the horizontal plate and the connecting plate are connected by the second horizontal push rod to form a transmission connection.

[0014] Furthermore, the rear upright plate can be adjusted in horizontal position via a second horizontal push rod.

[0015] Furthermore, a gap is provided between the slitting blade and the side plate, the gap being greater than the minimum retraction length of the interlocking plate.

[0016] This utility model provides a slitting device for paper product manufacturing, which has the following advantages:

[0017] 1. In this utility model, the slitting device uses a top pressure plate on the front to press down and fix the slitting point of the paper product, reducing the shaking and offset of the slitting surface. The rear pressure plate is connected by a spring compression rod on the rear side, which uses elastic pressing to prevent the other end of the paper product to be slit from tilting up, thus maintaining the stability of the paper product during slitting.

[0018] The upper surface of the top pressure plate is provided with a top arc plate, which can guide the cutting blade to press down more smoothly.

[0019] The rear pressure plate is adjusted horizontally via a horizontal plate driven by a second horizontal push rod at the top. This allows for adjustment based on the length of the paper product, accommodating different specifications and better meeting processing needs.

[0020] 2. In this utility model, the slitting blade is suspended and detachably fixed by a top-side clamping plate. There is a gap between the two sides of the slitting blade and the side plate, which is used to accommodate the V-shaped scraper.

[0021] Guided by the crossbar and the first horizontal push rod, the V-shaped scrapers on both sides can move to the sides, so that the V-shaped scrapers are removed from under the slitting blade, thereby ensuring the normal slitting operation of the slitting blade.

[0022] The V-shaped scrapers on both sides can move below the slitting blade after it is lifted, thereby preventing the slitting blade from falling and reducing safety impact.

[0023] 3. In this utility model, the moving distance of the V-shaped scraper can be sensed by the detection sensor on the V-shaped scraper and the fixed sensor sensing contact. When the detection sensor reaches the horizontal position of the sensor sensing contact, the first horizontal push rod is controlled to move. This control is efficient and convenient, greatly improving the ease of use for the operator.

[0024] The V-shaped scraper can also move laterally along a longer trajectory under control to scrape and clean the surface of the slitting blade, removing the residue that adheres to the blade during slitting and ensuring high efficiency during the slitting process. Attached Figure Description
