Description

Technical Field

[0001] This utility model relates to the technical field of film slitting machines, and in particular to a slitting blade assembly for film bodies. Background Technology

[0002] The film slitting machine consists of an unwinding mechanism, a cutting mechanism, a winding mechanism, various functional rollers, and tension control, correction, and detection devices. Its working principle is as follows: the metallized film raw material released from the unwinding mechanism passes through the flattening roller, tension detection roller, energizing roller, and correction system before entering the cutting mechanism. After being slit, the raw material is wound into standard film rolls by the winding mechanism.

[0003] When cutting film using a film slitting machine, the cutting blade needs to be cleaned or replaced after long-term use. The cutting blades of existing film slitting machines are generally fixed with bolts, and replacement requires disassembly and installation using wrenches and screwdrivers, which is quite troublesome.

[0021] 1. Equipped with a mounting bracket, scraping mechanism, scraping frame, blade holder, connecting mechanism, cutting blade, and mounting platform, the device allows for blade replacement by activating the cylinder. The piston rod of the cylinder moves the mounting block upwards, which in turn moves the connecting block and the cutting blade upwards. As the cutting blade moves upwards, any residual film on its surface is scraped off, squeezing the two L-shaped locking blocks. This causes the L-shaped locking blocks to retract into the connecting groove, and the protruding L-shaped locking blocks disengage from the groove. Pulling the cutting blade downwards separates the mounting block and the connecting block, allowing the cutting blade to be detached for replacement with other cutting blades. This convenient feature makes blade replacement easier and more convenient to use.

[0022] 2. Equipped with an adjustment mechanism and a lifting mechanism, starting the motor causes the output end of the motor to drive the bidirectional lead screw to rotate, the mounting platform moves on the surface of the bidirectional lead screw, and the mounting platform drives the cutting blade to move. The position of the cutting blade can be adjusted according to the required film width for cutting. Starting the hydraulic cylinder can drive the moving block to move up and down, so that the cutting blade can be adjusted in height for cutting. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0030] Reference Figure 1-5 This utility model discloses a slitting blade assembly for a membrane, including a mounting frame 1. A blade holder 2 is slidably disposed between the side walls of the mounting frame 1. Two mounting platforms 4 are slidably disposed at the lower end of the blade holder 2. A cutting blade 3 is disposed below each of the two mounting platforms 4, and the two cutting blades 3 respectively movably pass through the upper ends of the two mounting platforms 4. A connecting mechanism 7 is disposed above each of the two cutting blades 3. Each connecting mechanism 7 includes a connecting block 701, a connecting groove 702, two slots 703, a mounting block 704, two springs 705, two L-shaped locking blocks 706, and two mounting grooves 707. The connecting block 701 is fixedly connected to the upper end of the cutting blade 3. The connecting groove 702 is opened at the upper end of the connecting block 701. The two slots 703 are respectively opened on the two side walls of the connecting groove 702. The mounting block 704 is disposed above the connecting block 701. The two mounting grooves 707 are both opened at the lower end of the mounting block 704. The two springs 705 and 706 are respectively opened at the two side walls of the connecting groove 702. Two L-shaped blocks 705 are fixedly connected to one side wall of two mounting slots 707, and two L-shaped blocks 706 are fixedly connected to the other side of two springs 705. The two L-shaped blocks 706 are slidably connected in two slots 703. When the cutting blade 3 needs to be replaced, the cylinder 501 is activated. The piston rod of the cylinder 501 drives the mounting block 704 to move upward. The mounting block 704 drives the connecting block 701 and the cutting blade 3 to move upward. During the upward movement of the cutting blade 3, the residual film on the surface is scraped off, squeezing the two L-shaped blocks 706, so that the L-shaped blocks 706 can retract into the connecting slot 702. The protrusion of the L-shaped blocks 706 leaves the slot 703, and the cutting blade 3 is pulled downward, so that the mounting block 704 and the connecting block 701 are separated, thereby allowing the cutting blade 3 to be disassembled and replaced with other cutting blades 3. This makes it easier to replace the cutting blade 3 and makes it more convenient to use.

[0031] A round rod 708 is fixedly connected between the side walls of the two mounting slots 707. Two L-shaped blocks 706 are slidably connected to the circumferential side of the round rod 708. The sliding cooperation between the L-shaped blocks 706 and the round rod 708 can improve the movement stability of the L-shaped blocks 706.

[0032] Both mounting platforms 4 are equipped with scraping mechanisms 5 at their upper ends. Each scraping mechanism 5 includes a cylinder 501 and an L-shaped plate 502. The L-shaped plate 502 is fixedly connected to the upper end of the mounting platform 4, and the cylinder 501 is fixedly connected to the upper end of the L-shaped plate 502. The piston rod of the cylinder 501 moves through the lower end of the L-shaped plate 502 and is fixed to the mounting block 704. Both mounting platforms 4 are fixedly connected with scraping frames 9 at their lower ends. Two cutting blades 3 are respectively set in the two scraping frames 9. When the cutting blades 3 are cutting, some film that does not contain heat will remain on the surface of the cutting blades 3. While the scraping mechanism 5 drives the cutting blades 3 to move upward, the scraping frames 9 can scrape the surface of the cutting blades 3. It is not necessary to disassemble them before scraping. The surface of the cutting blades 3 can be scraped and cleaned when they leave the bottom of the mounting platform 4.

[0033] An adjustment mechanism 8 is provided below the blade holder 2. The adjustment mechanism 8 includes a motor 801, a bidirectional lead screw 802, and a rectangular groove 804. The rectangular groove 804 is located at the lower end of the blade holder 2. The motor 801 is fixedly connected to one side wall of the rectangular groove 804. The bidirectional lead screw 802 is fixedly connected to the output end of the motor 801 and rotatably connected to the other side wall of the rectangular groove 804. Both mounting platforms 4 are threadedly connected to the circumferential side of the bidirectional lead screw 802 through lead screw nuts. When the motor 801 is started, the output end of the motor 801 drives the bidirectional lead screw 802 to rotate. The mounting platform 4 moves on the surface of the bidirectional lead screw 802, and the mounting platform 4 drives the cutting blade 3 to move. The position of the cutting blade 3 can be adjusted according to the required film width for cutting.

[0034] Two limiting rods 803 are fixedly connected between the side walls of the rectangular groove 804. The mounting platform 4 is slidably connected to the circumferential side of the two limiting rods 803. The sliding cooperation between the mounting platform 4 and the limiting rods 803 can improve the movement stability of the mounting platform 4.

[0035] Lifting mechanisms 6 are provided on both sides of the tool holder 2. Each lifting mechanism 6 includes a lifting groove 601, a moving block 602, and a hydraulic cylinder 603. The lifting groove 601 is opened on one side wall of the mounting frame 1. The hydraulic cylinder 603 is fixedly connected to the inner top wall of the lifting groove 601. The moving block 602 is fixedly connected to the lower end of the output end of the hydraulic cylinder 603. The lifting mechanism 6 can drive the tool holder 2 to move up and down to adjust the height for cutting. When the hydraulic cylinder 603 is activated, the hydraulic cylinder 603 can drive the moving block 602 to move up and down, so that the cutting blade 3 can adjust the height for cutting.

[0036] Two slide rods 604 are fixedly connected between the inner top wall and the inner bottom wall of the lifting groove 601. The moving block 602 is slidably connected to the circumferential side of the two slide rods 604. The sliding cooperation between the moving block 602 and the slide rods 604 can improve the movement stability of the moving block 602.

[0037] The implementation principle of the above embodiment is as follows: When the cutting blade 3 needs to be replaced, the cylinder 501 is activated. The piston rod of the cylinder 501 drives the mounting block 704 to move upward. The mounting block 704 drives the connecting block 701 and the cutting blade 3 to move upward. During the upward movement of the cutting blade 3, the residual film on the surface is scraped off, squeezing the two L-shaped locking blocks 706, so that the L-shaped locking blocks 706 can retract into the connecting groove 702. The protrusion of the L-shaped locking blocks 706 leaves the locking groove 703, pulling the cutting blade 3 downward. The mounting block 704 and the connecting block 701 are respectively installed. Similarly, when installation is required, the two L-shaped locking blocks 706 are inserted into the connecting groove 702. The spring 705 is compressed when the L-shaped locking blocks 706 enter the connecting groove 702. When the protrusion of the L-shaped locking blocks 706 reaches the locking groove 703, the spring 705 returns due to its own elasticity and locks into the locking groove 703, thereby allowing the cutting blade 3 to be disassembled and installed. Other cutting blades 3 can be replaced, making the replacement of the cutting blade 3 more convenient and simple.
