Description

Technical Field

[0001] This application relates to the field of clamping mechanism technology, and in particular to a clamping mechanism for a high-speed plastic flexible packaging slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide strips of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape production, and printing and packaging machinery. Slitting machines are mainly used for cutting non-woven fabrics, mica tape, paper, insulating materials, and various film materials, and are particularly suitable for cutting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, film, etc.).

[0003] When using a slitting machine, the raw material roll needs to be installed onto the equipment. However, the existing slitting machine's raw material roll limiting mechanism cannot adjust its height. Therefore, the raw material roll needs to be manually lifted to the installation height to complete the installation, which is inconvenient and labor-intensive. Therefore, in order to correct the above defects, we propose a clamping mechanism for a high-speed plastic flexible packaging slitting machine. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and drawings of this application are intended to cover without excluding other terms. The words "a" or "an" do not exclude the presence of multiples. Unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple sets" means two or more (including two sets).

[0021] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative.

For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application provides a clamping mechanism for a high-speed plastic flexible packaging slitting machine, including a positioning block 1. A pair of housings 2 are fixedly connected to the side wall of the positioning block 1. A first motor 3 is fixedly connected to the top of the housing 2. The output shaft of the first motor 3 passes through the top of the housing 2. A transmission block 4 is provided inside the housing 2. A threaded hole is opened on the transmission block 4, and a lead screw 5 is threadedly connected to the threaded hole. The top end of the lead screw 5 is fixedly connected to the output shaft of the first motor 3, and the bottom end of the lead screw 5 is movably connected to the inner wall of the housing 2. The side wall of the transmission block 4 is fixedly connected to the first motor 3. A connecting block 6 is fixedly connected to the housing 2. A movable opening 7 is provided on the side wall of the housing 2. The other side of the connecting block 6 passes through the movable opening 7 and is fixedly connected to the positioning chamber 8. The raw material roll can be positioned by the first clamping roller 11 and the second clamping roller 12. A second motor 9 and a hydraulic cylinder 10 are fixedly connected to the inner walls of the pair of positioning chambers 8 respectively. The output shaft of the second motor 9 passes through the side wall of the positioning chamber 8 and is fixedly connected to the first clamping roller 11. The output shaft of the hydraulic cylinder 10 passes through the side wall of the positioning chamber 8 and is movably connected to the second clamping roller 12.

[0026] In the technical solution of this application embodiment, the device can be easily installed and disassembled by the second snap-fit ​​roller 12 and bolts 14. A fixing plate 13 is fixedly connected to the side walls of a pair of housings 2 that are far apart. A pair of bolts 14 passes through each fixing plate 13, and each pair of bolts 14 is symmetrically arranged about the central axis of the fixing plate 13.

[0027] In the technical solution of this application embodiment, to prevent the transmission block 4 from shaking and improve the stability of the transmission block 4, the width of each transmission block 4 is equal to the width of the inner cavity of the housing 2, and the width of each transmission block 4 is equal to the width of the movable opening 7.

[0028] Working principle: In use, the device is installed on the slitting machine housing using bolts 14. When the raw material roll needs to be installed, the first motor 3 is started. The first motor 3 drives the lead screw 5 to rotate. Through the threaded engagement between the lead screw 5 and the transmission block 4, the transmission block 4 moves up and down. The transmission block 4 drives the positioning chamber 8 to move up and down through the connecting block 6, thereby changing the height of the first clamping roller 11 and the second clamping roller 12 until the first clamping roller 11 and the second clamping roller 12 move to the center of the raw material roll and clamp the center of the raw material roll onto the first clamping roller 11. Then, the hydraulic cylinder 10 is started, and the hydraulic cylinder 10 pushes the second clamping roller 12 into the center of the raw material roll, thereby completing the installation of the raw material roll. Then, the first motor 3 is started, and the first motor 3 drives the transmission block 4 to move upward through the lead screw 5. The transmission block 4 drives the positioning chamber 8 to move upward through the connecting block 6, thereby lifting the raw material roll. When it is necessary to rotate the raw material roll, the second motor 9 is started, and the second motor 9 drives the raw material roll to rotate.
