Description

Technical Field

[0001] This utility model belongs to the field of packaging paper cutting technology, and specifically relates to a pre-compression structure for fixed-distance cutting of food packaging paper. Background Technology

[0002] The existing food packaging paper fixed-distance cutting machine is a device used to precisely cut food packaging paper according to a set length. It can cut rolls of packaging paper into sheets or strips of uniform size to meet different food packaging needs.

[0003] The current food packaging paper cutting pre-compression structure is a device that pre-compresses the paper before it is cut by the cutting machine. Its purpose is to ensure that the packaging paper remains flat and stable during the cutting process, avoiding deviation, wrinkles, etc., thereby improving the cutting accuracy and quality of the packaging paper when it is cut by the cutting machine.

[0004] However, in existing food packaging paper cutting and pre-compression structures, the spring-loaded plate type pre-compression structure generally requires multiple springs to compress the packaging paper when it is necessary to compress the packaging paper with a large width. If one of the springs fails during long-term use, it will directly cause the compression of the packaging paper by the structure to deviate, affecting the cutting of the packaging paper by the device. Maintenance requires the replacement of the entire device, which increases the maintenance cost. Utility Model Content

[0005] The purpose of this utility model is to address the pre-compression structure for spaced cutting of food packaging paper. Its advantage is that when the elastic coefficient of the internal compression spring decreases and the deformation becomes irreversible after long-term use, the problematic compression spring area can be quickly disassembled.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pre-compression structure for cutting food packaging paper at a fixed distance, including a positioning frame, wherein the top of the positioning frame is provided with twenty-five positioning slots from left to right, and a compression component is slidably connected to the inner cavity of the positioning slots; positioning plates are fixedly installed on both sides of the positioning frame; a positioning rod is fixedly installed between the opposite sides of the two positioning plates; an mounting plate is snapped between the surfaces of the two positioning rods; and the bottom of the mounting plate is snapped with the compression component and slidably connected to the positioning frame.

[0007] Using the above technical solution: When springs that have experienced problems such as decreased elasticity coefficient and irreversible deformation need to be disassembled after long-term use, the positioning shell and limiting shell in the clamping assembly can be used together to detach the structure connecting the three internally fixed clamping springs from the positioning frame, thus completing the disassembly of springs that have experienced problems such as decreased elasticity coefficient and irreversible deformation after long-term use; and when it is necessary to quickly disassemble and assemble the clamping assembly and the positioning frame, the user can remove the bolts on both sides and pull the mounting plate upwards to quickly disassemble the clamping assembly when problems occur.

[0008] The present invention is further configured such that threaded sleeves are fixedly installed on both sides of the positioning frame, and the two threaded sleeves are fixedly installed to the mounting plate by bolts on the opposite sides.

[0009] The above technical solution is adopted: the mounting plate is firmly fixed to both sides of the positioning frame by the cooperation of the threaded sleeve and the bolt, ensuring the longitudinal limit stability of the mounting plate on the pressing component and preventing the pressing component from shifting upward due to vibration or paper tension during the pre-pressing operation. The detachability of the connection by the two bolts facilitates the subsequent disassembly of the mounting plate.

[0010] The present invention is further configured such that L-shaped fixing plates are fixedly installed on both sides of the opposite side of the two positioning plates, and the surface of the L-shaped fixing plates is slidably connected to the mounting plate.

[0011] The above technical solution is adopted: the sliding trajectory of the mounting plate is laterally constrained by the L-shaped fixing plate, ensuring that the mounting plate always moves in a direction parallel to the positioning frame when it is disassembled or adjusted, and avoiding misalignment of the mounting plate with the clamping component due to offset.

[0012] The present invention is further configured such that the clamping assembly includes a positioning shell, the surface of the positioning shell is slidably connected to the inner cavity of the positioning frame, three clamping springs are fixedly installed on the top of the inner cavity of the positioning shell, a connecting rod is fixedly installed on the bottom of the clamping springs, a pressure block is fixedly installed on the bottom of the connecting rod, and a limit shell is engaged with the right side of the positioning shell.

[0013] The above technical solution provides installation space for the compression springs and connecting rods through the combined use of the positioning shell and the limiting shell. The three equidistantly distributed compression springs can evenly transmit elastic force, which drives the pressure block through the connecting rod to form a stable pre-compression force on the food packaging paper, preventing the paper from shifting during the cutting process. At the same time, the snap-fit ​​between the limiting shell and the positioning shell facilitates quick disassembly. When the compression springs experience a decrease in elasticity or deformation, the internal components can be removed for inspection and replacement by opening the limiting shell, without the need to completely disassemble the compression components, thus improving maintenance efficiency.

[0014] The present invention is further configured such that limiting plates are fixedly installed on both sides of the positioning shell, and a locking plate is slidably connected to the inner cavity of the limiting plate, and the two locking plates are slidably connected to the mounting plate on opposite sides.

[0015] The above technical solution is adopted: the installation position of the mounting plate is positioned by the snap-fit ​​between the locking plate and the positioning frame, so as to prevent it from falling off the positioning groove during use and ensure that the pressure block is always aligned with the pre-pressing position.

[0016] The present invention is further configured such that mounting shells are fixedly installed on both sides of the top right side of the positioning shell, and mounting rods are snapped into the inner cavity of the mounting shells, with the right side of the mounting rods fixedly installed to the limiting shells.

[0017] The above technical solution achieves quick docking and fixation of the limiting shell and the positioning shell by snapping the mounting rod with the mounting shell, which facilitates the user's installation of the limiting shell and the positioning shell and avoids deviations during the installation process.

[0018] In summary, this utility model has the following beneficial effects: 1. When springs that have experienced a decrease in elasticity coefficient or irreversible deformation after long-term use need to be disassembled, the positioning shell and limiting shell in the clamping assembly can be used together to detach the structure connecting the three internally fixed clamping springs from the positioning frame, thus completing the disassembly of springs that have experienced a decrease in elasticity coefficient or irreversible deformation after long-term use. 2. When it is necessary to quickly disassemble and assemble the clamping assembly and the positioning frame, the user can remove the bolts on both sides and pull the mounting plate upwards to quickly disassemble the clamping assembly if there is a problem.

[0025] Brief description of usage: When springs exhibiting problems such as decreased elasticity or irreversible deformation after prolonged use need to be disassembled, the positioning shell 301 and limiting shell 305 in the clamping assembly 3 can be used together to detach the structure connecting the three internally fixed clamping springs 302 from the positioning frame 1. This allows for the disassembly of springs exhibiting problems such as decreased elasticity or irreversible deformation after prolonged use. After detachment, the positioning shell 301 and limiting shell 305 can be directly disassembled to inspect the problematic springs inside, further facilitating the user's identification of issues. The spring of the problem is tested; the mounting plate 6 is firmly fixed to both sides of the positioning frame 1 by the cooperation of the threaded sleeve 7 and the bolt 8, so as to ensure the longitudinal limit stability of the mounting plate 6 on the pressing component 3 and prevent the pressing component 3 from shifting upward due to vibration or paper tension during the pre-pressing operation. The detachability of the connection by the two bolts 8 facilitates the subsequent disassembly of the mounting plate 6; the L-shaped fixing plate 9 forms a lateral constraint on the sliding trajectory of the mounting plate 6, ensuring that the mounting plate 6 always moves in a direction parallel to the positioning frame 1 when it is disassembled or adjusted, and avoids the mounting plate 6 shifting and causing misalignment with the pressing component 3.

[0030] Brief description of usage: When quick disassembly and assembly of the clamping assembly 3 and the positioning frame 1 are required, the user can remove the bolts 8 on both sides and pull the mounting plate 6 upwards to quickly disassemble the clamping assembly 3 if a problem occurs. The positioning shell 301 and the limiting shell 305 work together to provide installation space for the clamping springs 302 and the connecting rod 303. The three equidistantly distributed clamping springs 302 can evenly transmit elastic force, which, through the connecting rod 303, drives the pressure block 304 to form a stable pre-clamping force on the food packaging paper, preventing the paper from shifting during cutting. Simultaneously, the locking mechanism between the limiting shell 305 and the positioning shell 301 facilitates quick... Quick disassembly: When the compression spring 302 experiences a decrease in elasticity or deformation, the internal components can be removed for inspection and replacement by opening the limiting shell 305, without the need for complete disassembly of the compression assembly 3, thus improving maintenance efficiency; the mounting plate 6 is positioned by engaging with the positioning frame 1 through the locking plate 307, preventing it from disengaging from the positioning groove 2 during use and ensuring that the pressure block 304 is always aligned with the pre-compression position; the limiting shell 305 and the positioning shell 301 are quickly connected and fixed by engaging with the mounting shell 308 through the mounting rod 309, facilitating the user's installation of the limiting shell 305 and the positioning shell 301 and avoiding deviations during installation.
