Description

Technical Field

[0001] This invention relates to the field of heat insulation film processing, and in particular to a cutting device for heat insulation film production. Background Technology

[0002] The field of heat insulation film cutting technology encompasses various cutting-related technologies in the heat insulation film production process. Its core content lies in the precise and efficient division of heat insulation film into required sizes and shapes, covering everything from basic manual cutting methods to the use of various automated and semi-automated cutting equipment and supporting technologies to meet the diverse cutting needs of heat insulation film in different application scenarios.

[0003] One type of cutting device for heat insulation film production refers to cutting equipment specifically designed for use in the heat insulation film production process. This device addresses various cutting tasks related to heat insulation film, including fixed-length cutting of roll heat insulation film and shape cutting of sheet heat insulation film. It typically employs a mechanical transmission structure, such as a motor driving a screw and nut mechanism to move the cutting blade; a clamping assembly uses a cylinder to push a pressure plate to fix the heat insulation film on the cutting table, preventing displacement during cutting; and it is also equipped with cutting blades, such as high-speed rotating circular blades or reciprocating straight blades, to complete the cutting action of the heat insulation film.

[0004] Existing technologies use a motor to drive a screw and nut mechanism to move the cutting tool. When cutting to a fixed length, parameters need to be adjusted frequently, resulting in cumbersome operation and low efficiency. Using a cylinder to push a pressure plate to fix the heat insulation film can easily cause wrinkles or burrs on the cut surface due to uneven pressure, affecting product quality. Relying on manual handling of the cut heat insulation film makes continuous operation impossible, increases labor costs, and limits production efficiency. Summary of the Invention

[0044] Under the driving action of the cutting drive assembly 53, the upper sliding block 523 and the lower sliding block 521 are driven to move closer to each other, the air cushions 522 arranged on the lower sliding block 521 clamp the thermal insulation film together with the lower end of the upper sliding block 523, so that the thermal insulation film is taut between the lower sliding block 521 and the straight sliding groove 525, and the cable three 524 is driven to slide in the straight sliding groove 525 by the motor, at this time, the cutting knife 526 slides in the straight sliding groove 525 from left to right or from right to left under the action of the cable three 524, and then cuts the taut thermal insulation film;

[0048] Further, when the hydraulic driver 55 extracts the hydraulic oil in the relay cavity 536 through the communication pipe four 535, the trapezoidal block two 533 moves away from the lower slide block 521 and the upper slide block 523, at this time, under the action of the spring rod 531, the lower slide block 521 and the upper slide block 523 move away from each other, at this time, the receiving structure 4 can pull out the heat insulation film clamped between the lower slide block 521 and the upper slide block 523, and at the same time, the hydraulic driver 55 retransports the heat insulation film forward to make it pass the range of the lower slide block 521 and the upper slide block 523, facilitating the subsequent receiving structure 4 to clamp and pull the heat insulation film.

[0049] In example three, based on example two, the power disc 424 in the receiving drive assembly 42 drives the cable one 422 to drive the sliding block 45 to slide in the T-shaped sliding groove 421, cooperate with the arc-shaped protrusions 4231 and the trapezoidal block 4232 on the limiting plate 423, act on the linkage wheel 434 of the U-shaped plate 43, make the thimble 432 move in the hydraulic groove 433, control the driving slide block 443 and the clamping arm 442 of the clamping assembly 44 through the communication pipe one 431 and the communication pipe two 446, realize the clamping and pulling of the heat insulation film; at the same time, the U-shaped plate 43 drives the clamping assembly 44 to send the cut heat insulation film into the receiving groove 41, cooperate with the cutting structure 5 to realize continuous cutting operation and automatic collection.

[0050] Further, referring to Figure 6 , the receiving structure 4 includes the receiving groove 41 movably installed on the upper end of the bottom plate 2, the receiving drive assembly 42 is symmetrically arranged on the upper end of the bottom plate 2 along the receiving groove 41, the inner surfaces of the two receiving drive assemblies 42 are slidably connected with the sliding blocks 45, the upper ends of the two sliding blocks 45 are commonly provided with the U-shaped plate 43, and the rear end of the U-shaped plate 43 is fixedly connected with a plurality of clamping assemblies 44 in array.

[0053] Through the action of the power disc 424 on the cable I 422, when the cable I 422 is rotated under the action of the motor, the cable I 422 will displace, thereby pulling the sliding block 45 to slide in the T-shaped sliding groove 421.

[0054] Further, when the sliding block 45 slides in the receiving material groove 41, the U-shaped plate 43 will be synchronously moved after a certain time delay, thereby driving the clamping assembly 44 to clamp or release the heat insulation film through the action of the limiting plate 423 on the U-shaped plate 43.

[0055] Further, refer to Figure 8 and Figure 9 The upper end of the sliding block 45 is slidably connected with the inner surface of the U-shaped plate 43, a trapezoidal block I 451 is fixedly connected to the upper end of the sliding block 45, and a return groove 452 is arranged at the front end of the upper end of the trapezoidal block I 451.

[0057] When the sliding block 45 is pulled backward by the cable 422, the trapezoidal block 451 will push the U-shaped plate 43 backward at the same time, and the linkage wheel 434 will slide on the limiting plate 423, and when the linkage wheel 434 moves to the position of the arc-shaped protrusion 4231, it will move upward temporarily due to the action of the arc-shaped protrusion 4231, at this time, the bottom end of the thimble 432 will pass the rear end of the trapezoidal block 451, and then reach the inclined surface part of the trapezoidal block 451, at this time, the U-shaped plate 43 reaches the last side of the path and is attached to the front end of the mounting seat 51, and the clamping assembly 44 is in front of the lower sliding block 521 and the upper sliding block 523, the sliding block 45 continues to move with the cable 422, and the thimble 432 is gradually pushed upward along the hydraulic groove 433 through the inclined surface of the trapezoidal block 451, and finally falls into the return groove 452, at this time, the clamping assembly 44 has clamped the heat insulation film;

[0061] During the upward movement of the ejector pin 432, the hydraulic oil in the hydraulic groove 433 is pushed and enters each hydraulic chamber 444 through the communication pipe I 431 and the communication pipe II 446. During this process, the hydraulic oil pushes the piston rod 445 to move in the direction of the communication pipe I 431, that is, the clamping arms 442 are pushed to move closer to each other, at this time, the torsion rod 448 is rotated under the action of the cable II 447, thereby driving the clamping arms 442 to change from the vertical state to the horizontal state, until the heat insulation film is completely clamped between the two clamping arms 442;

[0062] When the linkage wheel 434 reaches the position of the trapezoidal block 4232, the ejector pin 432 is gradually reset under the action of the spring and the trapezoidal block I 451, at this time, the piston rod 445 and the drive sliding block 443 are reset under the action of the change of the hydraulic oil, and simultaneously drive the clamping arm 442 to reset, at this time, the torsion rod 448 drives the clamping arm 442 to change to the vertical state under the action of the torsional spring, further, the cable II 447 will be re-wound on the outer surface of the torsion rod 448, and during the opening process of the clamping arm 442, the heat insulation film will fall into the receiving groove 41 under the action of gravity and be temporarily stored, in the actual production process, the distance between the hydraulic chamber 444 and the receiving groove 41 can be adjusted by changing the height of the vertical part of the U-shaped plate 43, or an isolation cover can be installed above the bottom plate 2 to prevent the heat insulation film from deviating, but in the conventional production, due to the electrostatic effect, the heat insulation film will automatically adsorb and overlap together without additional operation.
