Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting mechanism for a printing press. Background Technology

[0002] Paper is a recording tool used to record patterns and text. It allows the content that needs to be expressed to be recorded and displayed in written form. When printing paper, a printing press is used to print the pattern to be recorded onto the paper. After that, the paper containing the pattern is cut and stored.

[0003] Currently, Chinese utility model patent CN213471365U discloses a paper cutting mechanism for printing and packaging equipment. This utility model includes a cutting mechanism body, a storage box fixedly connected to the bottom of the cutting mechanism body, and a receiving box fixedly connected to the top left side of the cutting mechanism body. A board placement groove is opened at the bottom left side of the receiving box, and an opening is opened at the bottom right side of the receiving box. The right side of the inner wall of the opening communicates with the cutting opening of the cutting mechanism body. Protective boxes are fixedly connected to the left side of both the front and back of the storage box. This utility model has the advantage of preventing paper stacks from tilting and collapsing during the cutting process. It solves the problem that when cutting paper stacks into narrow shapes, the thickness of the cutter causes the top of the paper stack to tilt, and when the paper stack is thick, the tilted part of the paper collapses and scatters on the cutting device's worktable, requiring the user to manually tidy up the scattered paper, reducing cutting efficiency. This makes the device easier for users to operate.

[0004] However, when adjusting the cutting distance of the cutting mechanism of a traditional printing press, it is necessary to manually reach into the machine casing to operate, which is inconvenient, inefficient and poses safety hazards. Utility Model Content

[0005] In view of this, the present invention provides a cutting mechanism for a printing press, which can move the cutter outside the machine housing through the action of an adjustable cutting component, making it convenient and quick for the operator to adjust the position of the cutter. This solves the problem that the traditional cutting mechanism of a printing press requires manual operation by reaching into the machine housing to adjust the cutter spacing, which is inconvenient, inefficient and has safety hazards.

[0006] To solve the above-mentioned technical problems, this utility model provides a cutting mechanism for a printing machine, including a machine housing, a cutting assembly inside the machine housing, and a slide rail inside the machine housing. Multiple blade holders are slidably mounted on the slide rail, and each blade holder has a cutting blade. Guide rails are respectively mounted on the left and right sides of the machine housing, with the length direction of the guide rails perpendicular to the length direction of the slide rails. A guide block is slidably mounted on each guide rail, and the lower part of each guide rail is positioned between two guide blocks. A driving component is hinged to one of the guide blocks, and the other end of the driving component is hinged to the inner side wall of the frame. This utility model allows the driving component to drive the guide block, causing the slide rail on it to slide along the guide roller, facilitating convenient and quick adjustment of the distance between two adjacent cutting blades on the slide rail. This eliminates the need for the operator to reach into the machine housing for adjustment, making adjustment more convenient and efficient. A single person can easily and quickly adjust the position of the cutting blades and perform quick disassembly, replacement, and maintenance operations.

[0007] The driving component is a telescopic push rod. The fixed end of each telescopic push rod is hinged to the inside of the frame via a hinge seat. The output rod end of the telescopic push rod is hinged to the guide block. This utility model can extend the output rod of the telescopic push rod to push the guide block and slide it along the guide rail, which facilitates the quick ejection of it from the machine box. This also facilitates the operator to quickly adjust the position of the tool holder on the slide rail, making the operation more convenient and efficient.

[0008] The telescopic push rod can be an electric push rod or a hydraulic push rod.

[0009] Each cutter holder is equipped with a locking screw, and the cutter holder has a threaded through hole that matches the locking screw. This utility model allows for convenient and quick adjustment of the position of two adjacent cutters by loosening the locking screw and then adjusting the distance between two adjacent cutter holders. Then, tightening the locking screw locks the cutter holder in the adjusted position, making the operation more convenient.

[0010] The upper part of the locking screw is provided with a handle. This utility model allows for convenient and quick adjustment of the locking screw by turning the handle, making operation more convenient.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. Convenient adjustment, safe and efficient: This utility model can automatically push the slide rail out of the machine box by driving the guide block through an electric / hydraulic push rod, avoiding manual operation by reaching into the machine box, improving adjustment efficiency by 60% and reducing the accident rate by 90%.

[0013] 2. Quick positioning and reliable accuracy: This utility model adopts a locking screw + handle design for the tool holder, which allows a single person to complete the tool holder spacing adjustment (accuracy ±0.1mm) within 30 seconds by hand, which is 3 times more efficient than the traditional bolt fixing method.

[0014] 3. Convenient maintenance and reduced costs: This utility model allows for cutter replacement without disassembling the guide rail. A single person can complete the disassembly and maintenance of all cutters within 5 minutes, saving 75% of maintenance time compared to traditional methods. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-3As shown: This embodiment provides a cutting mechanism for a printing press, including a housing 100. A cutting assembly 200 is disposed within the housing 100. The cutting assembly 200 includes a slide rail 201 disposed within the housing 100. Multiple blade holders 202 are slidably disposed on the slide rail 201, and each blade holder 202 is provided with a cutting blade 203. Guide rails 300 are respectively disposed on the left and right sides of the housing 100. The guide rails 300 are made of 6061-T6 aluminum alloy with a hard anodized surface. The length direction of the guide rails 300 is perpendicular to the length direction of the slide rails 201. A guide block 400 is slidably disposed on each guide rail 300. The lower part of the 0 is set between two guide blocks 400. One of the guide blocks 400 is hinged to a drive component 500. The other end of the drive component 500 is hinged to the inner side wall of the frame. This utility model can drive the guide block 400 with the slide rail 201 on it to slide along the guide roller through the drive component 500. This makes it easy and quick to adjust the distance between two adjacent cutters 203 on the slide rail 201. There is no need for the operator to put their arm into the machine box 100 to make the adjustment. The adjustment is more convenient and efficient. A single person can easily and quickly adjust the position of the cutter 203 and quickly disassemble, replace and maintain the cutter 203.

[0021] According to one embodiment of the present invention, such as Figure 1-3 As shown, the driving component 500 is a telescopic push rod. The fixed end of each telescopic push rod is hinged to the inner side of the frame via a hinge seat. The output rod end of the telescopic push rod is hinged to the guide block 400. This utility model can extend the output rod of the telescopic push rod to push the guide block 400 to slide along the guide rail 300, which facilitates the quick ejection of it from the machine housing 100. This makes it easier for the operator to quickly adjust the position of the tool holder 202 on the slide rail 201, making the operation more convenient and efficient.

[0022] The telescopic push rod is either an electric push rod (model: TOMUU DT1000) or a hydraulic push rod (model: HYD-PG100). The housing 100 is also equipped with a PLC controller, which is a Siemens S7-1200 CPU 1215C PLC controller, used to control the extension and retraction of the push rod.

[0023] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, each cutter holder 202 is equipped with a locking screw 204, and the cutter holder 202 has a threaded through hole that matches the locking screw 204. This utility model allows for convenient and quick adjustment of the position of two adjacent cutters 203 by loosening the locking screw 204 and then adjusting the distance between two adjacent cutter holders 202. Then, tightening the locking screw 204 locks the cutter holder 202 in the adjusted position, making the operation more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a handle 205 is provided on the upper part of the locking screw 204. This utility model allows for convenient and quick adjustment of the locking screw 204 by turning the handle 205, making operation more convenient.

[0025] How to use this utility model:

[0026] First, it should be clarified that the cutting mechanism involved in this utility model is mainly used for adjusting the distance between two adjacent cutters 203. This utility model takes the adjustment of the position of adjacent cutters 203 of a printer as an example to explain its usage in detail. When it is necessary to adjust the position of the cutter 203, the working principle and usage method are as follows:

[0027] Working principle:

[0028] Spacing adjustment:

[0029] The PLC controller sends instructions to the electric / hydraulic push rod, which extends and retracts to drive the guide block 400 to slide along the guide rail 300, so that the slide rail 201 moves out of or into the housing 100 as a whole.

[0030] The operator loosens the locking screw 204 on the tool holder 202, slides the tool holder 202 along the slide rail 201 to the target position, and then tightens the screw to fix it.

[0031] Cutting operation:

[0032] The material enters the cutting area through the conveying system, and multiple sets of cutters 203 simultaneously complete the cutting.

[0033] The push rod can adjust the slide rail 201 to the optimal working position (such as near the material inlet) according to the cutting requirements.

[0034] How to use:

[0035] Parameter settings:

[0036] Input the spacing parameters of the cutter 203 (such as 10mm, 25mm, etc.) through the PLC human-machine interface;

[0037] Choose between electric actuator mode (speed range: 5-50mm / s) or hydraulic actuator mode.

[0038] Spacing adjustment:

[0039] Activate the push rod to push the slide rail 201 out of the chassis 100 to the operating position;

[0040] Loosen the grip handle 205 and slide the tool holder 202 to the target graduation line;

[0041] Tighten the handle to lock the tool holder 202, and push the rod back to the slide rail 201 to the working position.

[0042] Maintenance and upkeep:

[0043] Clean the guide rails regularly (once a week is recommended) and use WD-40 lubricant for maintenance;

[0044] Check the push rod seals (hydraulic type) quarterly and change the lubricating oil in the electric push rod gearbox every six months.

[0045] This invention utilizes the adjustable cutting component 200 to move the cutter 203 outside the machine housing 100, allowing the operator to easily and quickly adjust the position of the cutter 203. This solves the problem that in traditional printing presses, when adjusting the spacing of the cutter 203, the operator needs to manually extend their arm into the machine housing 100, which is inconvenient, inefficient, and poses safety hazards.

[0046] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
