Description

Technical Field

[0001] This utility model belongs to the field of glass substrate product packaging technology, and relates to a paper cutter for packaging glass substrate products. Background Technology

[0002] In the glass substrate production process, product packaging is crucial, and the paper cutter is a key piece of equipment for cutting spacer paper to ensure proper packaging of the glass substrate. Currently, the paper cutters used for glass substrate packaging have certain operational characteristics, and also reveal some problems that urgently need to be addressed.

[0003] In existing paper cutters, during automatic operation, the blade holder moves back and forth along the guide rail to complete each cut of the spacer paper. Regarding blade usage, when the currently used blade reaches the end of its service life, the operator needs to manually disassemble the blade and install a blade in the opposite direction onto the blade holder to continue subsequent cutting operations.

[0004] Based on current usage of paper cutters, the equipment must be stopped once the cutter head reaches the end of its service life. At this point, operators need to use specialized tools and spend approximately 10 minutes disassembling and installing the cutter. This downtime significantly impacts the uptime of automated production lines. Uptime is a crucial indicator of production line efficiency; frequent downtime for cutter replacement disrupts the continuous and stable operation of the production line, reducing overall production efficiency. Furthermore, the frequent disassembly and installation of cutters by personnel poses significant safety hazards.

[0005] Existing paper cutters cut spacer paper by the reciprocating motion of the blade holder. This motion results in a relatively fixed point of friction between the spacer paper and the cutting blade. Over extended periods of cutting, this fixed friction point leads to accelerated wear on the blade tip, reducing its lifespan. This shortened blade lifespan not only increases the frequency of blade replacement and raises production costs but also further impacts the continuity and stability of the production line.

[0006] In summary, existing paper cutters for glass substrate packaging require frequent cutter head replacements, have short cutter head lifespans, and negatively impact production efficiency. Therefore, improvements and innovations are necessary to increase production efficiency, reduce costs, and ensure production safety. Utility Model Content

[0007] The purpose of this utility model is to provide a paper cutter for packaging glass substrate products, so as to solve the technical problem that the cutter head of the existing paper cutter has a short service life and requires frequent replacement, which affects the production efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a paper cutter for packaging glass substrate products, including a paper cutter mounted on a knife holder; the knife holder is connected to a telescopic cylinder; the telescopic cylinder is connected to one end of a connecting rod, and the other end of the connecting rod is connected to a transmission device; the middle part of the connecting rod is connected to the bottom of an interval paper output platform through a guide mechanism, and an opening is provided on the interval paper output platform for the paper cutter head to extend and cut.

[0009] Furthermore, the paper cutter has a cross-shaped structure, with a blade head installed at each of the four ends of the cross-shaped structure.

[0010] Furthermore, the blade holder has a square structure and a cross-shaped groove is provided on the blade holder for mounting the paper cutter.

[0011] Furthermore, the tool holder is also connected to a drive assembly, which can drive the tool head on the tool holder to rotate.

[0012] Furthermore, the driving component is a servo motor.

[0013] Furthermore, the connecting rod is arranged parallel to the paper output platform; one end of the connecting rod has a protrusion in its vertical direction; the protrusion is connected to a telescopic cylinder, which can drive the knife holder to move in the vertical direction.

[0014] Furthermore, the guiding mechanism is a guide rail; a slider is mounted on the guide rail; the slider is connected to the middle of the connecting rod.

[0015] Furthermore, the connection between the slider and the middle part of the connecting rod is either a snap-fit ​​or a threaded connection.

[0016] Furthermore, the transmission device is a belt.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a paper cutter for packaging glass substrate products. The transmission device and guiding mechanism drive the paper cutter to move left and right through a connecting rod for cutting. The paper cutter is moved vertically through a telescopic cylinder, which can adjust the contact point between the cutter head and the spacer paper, so that the cutting point is varied, reducing friction at a single point. This avoids the problem of the friction point between the cutter head and the spacer paper being fixed during long-term cutting, which leads to accelerated wear of the cutter head. This improves the service life of the paper cutter, reduces the number of cutter head replacements, achieves the purpose of cost reduction and efficiency improvement, saves working time, increases production line utilization, and avoids safety hazards caused by the operation.

[0018] Furthermore, the paper cutter of this invention has a symmetrical cross-shaped blade head structure, and the blade holder is connected to a servo motor, which can rotate 90° to replace the blade head, reducing the number of times the blade head needs to be replaced, thereby improving production efficiency.
