Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a quick-change cutting tool and a book cutting mechanism. Background Technology

[0002] Paper cutters are key equipment in the printing industry used to cut paper. They are mainly used for the post-processing of printed materials such as books, magazines, and brochures to ensure that the finished product is sized accurately and has neat edges. The paper cutter blade is the core component of the paper cutter and is mostly made of alloy materials such as high-speed steel and alloy steel.

[0003] When installing the paper cutter on the paper cutter, the main process is to connect the cutter to the mounting plate inside the cutter holder. There are several threaded pins on one side of the mounting plate. The threaded pins are inserted into the inner wall of the cutter and fixed with nuts. This installation method requires disassembling each nut separately when changing the cutter, which involves many steps and results in low efficiency in changing the cutter. Utility Model Content

[0004] This utility model addresses the problem that the installation method of fixing the cutter to the mounting plate using multiple threaded pins and nuts requires disassembling each nut individually when changing the cutter, resulting in numerous operation steps and low efficiency in changing the cutter. Therefore, this invention proposes a quick-change cutter and a book cutting mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-change cutting tool, comprising a fixing plate and a cutting edge plate, wherein the fixing plate is fixedly installed on one side of a mounting plate by a plurality of threaded pins and a plurality of nuts, the cutting edge plate is disposed at the bottom of the fixing plate, and a mounting device is provided between the mounting plate and the cutting edge plate, wherein the mounting device is configured to engage the cutting edge plate and the fixing plate by means of a locking strip.

[0006] The effect achieved by the above components is as follows: by dividing the complete knife into two parts, a fixed plate and a cutting edge plate, the fixed plate is responsible for fixing it to the mounting plate, and the cutting edge plate is responsible for cutting paper. The cutting edge plate and the fixed plate are connected by a locking strip. When the knife needs to be replaced, only the cutting edge plate needs to be disassembled and installed. This can effectively reduce the operation steps and improve the efficiency of knife replacement.

[0007] Preferably, the mounting device includes a retaining strip welded to one side of the blade plate, the outer surface of the retaining strip being inserted into the inner wall of the fixing plate, auxiliary blocks being installed at both ends of the fixing plate, and an L-shaped plate being slidably installed on the inner wall of the auxiliary block, with one side of the L-shaped plate abutting against one side of the blade plate.

[0008] The effect achieved by the above components is as follows: when the locking strip is inserted into the inner wall of the fixing plate and the L-shaped plate is pushed to slide on the inner wall of the auxiliary block, one side of the L-shaped plate abuts against one side of the blade plate. Then the two L-shaped plates can limit the two ends of the blade plate respectively, thereby fixing the blade plate to the fixing plate. At the same time, when the blade plate needs to be replaced, it is only necessary to push the blade plate to make the locking strip on the blade plate disengage from the fixing plate.

[0009] Preferably, the inner wall of the L-shaped plate is threaded with bolts, and an auxiliary groove is provided on one side of the inner wall of the auxiliary block, with the bolts forming the inner wall of the auxiliary groove.

[0010] The effect achieved by the above components is as follows: by setting the bolts and rotating the bolts so that one end of the bolt abuts against one side of the blade plate, the L-shaped plate can be fixed and the L-shaped plate can be prevented from shifting. At the same time, the two bolts can play an auxiliary role in fixing the blade plate.

[0011] Preferably, a spring is fixedly installed on one side of the L-shaped plate, and one end of the spring is fixedly installed on the top of the auxiliary block.

[0012] The effect achieved by the above components is that, by setting a spring, when the spring is not subjected to other external forces, that is, when the threaded pin is far away from the blade plate, the spring will stretch the L-shaped plate, so that the L-shaped plate will automatically move away from the blade plate, reducing the number of operation steps.

[0013] Preferably, the spring has a round rod inside, one end of which is fixedly mounted on the top of the auxiliary block, and the L-shaped plate is slidably disposed on the outer surface of the round rod.

[0014] The effect achieved by the above-mentioned components is that by setting the round rod, the round rod can limit and guide the spring, thereby preventing the spring from being damaged during deformation.

[0015] Preferably, an auxiliary component is provided on one side of the fixing plate. The auxiliary component includes an extension plate, which is welded to one side of the blade plate. Pins are symmetrically inserted into the inner wall of the extension plate, and one end of each of the two pins is symmetrically fixed to the bottom of the mounting plate.

[0016] The effect achieved by the above components is as follows: by setting an extension plate and inserting two pins into the inner wall of the extension plate, the pins can limit the extension plate and connect the blade plate and the mounting plate. This helps to prevent the blade plate from separating from the fixing plate from the side away from the locking strip, thereby improving the stability of the connection between the blade plate and the fixing plate.

[0017] Preferably, a rubber block is fixedly installed at one end of the pin, and one side of the rubber block abuts against one side of the extension plate.

[0018] The effect achieved by the above components is as follows: by setting the rubber block, after the pin is inserted into the inner wall of the extension plate, the extension plate will squeeze the rubber block, which can use the good deformation of the rubber block to assist in fixing the pin and the extension plate.

[0019] Preferably, the book cutting mechanism includes a paper cutter body, a blade holder, and a mounting plate. The blade holder is slidably disposed on the top of the paper cutter body, and the mounting plate is slidably disposed inside the blade holder.

[0020] The effect achieved by the above components is as follows: the inside of the blade holder is equipped with an electric telescopic rod (specifically referring to an electric paper cutter; if it is a hydraulic paper cutter, it should be a hydraulic rod). The electric telescopic rod can drive the blade connected to the mounting plate to move downward, thereby driving the blade to cut the paper.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the complete tool is divided into two parts: a fixing plate and a cutting edge plate. The fixing plate is responsible for fixing the tool to the mounting plate, and the cutting edge plate is responsible for cutting paper. The cutting edge plate and the fixing plate are connected by a locking strip. When the tool needs to be replaced, only the cutting edge plate needs to be disassembled and installed. This can effectively reduce the operation steps and thus improve the efficiency of tool replacement. Attached Figure Description

[0028] Example 1, referring to Figures 2-3As shown, this embodiment discloses a quick-changeable cutting tool and a paper-cutting mechanism for printing, including a fixed plate 1 and a cutting edge 2. The fixed plate 1 is fixedly installed on one side of a mounting plate 7 by several threaded pins and several nuts. The cutting edge 2 is located at the bottom of the fixed plate 1. An installation device 3 is provided between the mounting plate 7 and the cutting edge 2. The installation device 3 uses a locking strip 31 to engage the cutting edge 2 and the fixed plate 1. By dividing the complete cutting tool into two parts, the fixed plate 1 and the cutting edge 2, the fixed plate 1 is responsible for fixing to the mounting plate 7, and the cutting edge 2 is responsible for cutting paper. The cutting edge 2 and the fixed plate 1 are engaged by the locking strip 31. When the cutting tool needs to be replaced, only the cutting edge 2 needs to be easily disassembled and installed, which can effectively reduce the operation steps and improve the efficiency of cutting tool replacement.

[0029] Reference Figures 2-4 As shown, the mounting device 3 includes a retaining strip 31, which is welded to one side of the blade plate 2. The outer surface of the retaining strip 31 is inserted into the inner wall of the fixing plate 1. Auxiliary blocks 32 are installed at both ends of the fixing plate 1. L-shaped plates 33 are slidably mounted on the inner wall of the auxiliary blocks 32, with one side of the L-shaped plates 33 abutting against one side of the blade plate 2. When the retaining strip 31 is inserted into the inner wall of the fixing plate 1, and the L-shaped plates 33 are pushed to slide along the inner wall of the auxiliary blocks 32, one side of the L-shaped plates 33 abuts against one side of the blade plate 2. Thus, the two L-shaped plates 33 can respectively limit the two ends of the blade plate 2, thereby enabling the blade plate 2 to be positioned relative to the fixing plate 1. The fixed plates 1 are fixed together. When the blade plate 2 needs to be replaced, simply push the blade plate 2 so that the retaining strip 31 on the blade plate 2 is disengaged from the fixed plate 1. The inner wall of the L-shaped plate 33 is threaded with bolts 34. One side of the inner wall of the auxiliary block 32 is provided with an auxiliary groove 35. The bolts 34 are set in the inner wall of the auxiliary groove 35. By setting the bolts 34, rotating the bolts 34 so that one end of the bolts 34 abuts against one side of the blade plate 2, the L-shaped plate 33 can be fixed and prevented from shifting. At the same time, the two bolts 34 can play an auxiliary role in fixing the blade plate 2.

[0030] Reference Figure 3 and Figure 4 As shown, a spring 36 is fixedly installed on one side of the L-shaped plate 33, and one end of the spring 36 is fixedly installed on the top of the auxiliary block 32. By setting the spring 36, when there is no other external force, that is, when the threaded pin is away from the blade plate 2, the spring 36 will stretch the L-shaped plate 33, so that the L-shaped plate 33 will automatically move away from the blade plate 2, reducing the operation steps. A round rod 37 is set inside the spring 36, and one end of the round rod 37 is fixedly installed on the top of the auxiliary block 32. The L-shaped plate 33 is slidably set on the outer surface of the round rod 37. By setting the round rod 37, the round rod 37 can limit and guide the spring 36, thereby preventing the spring 36 from being damaged during deformation.

[0031] Reference Figure 3 and Figure 4 As shown, an auxiliary component 4 is provided on one side of the fixed plate 1. The auxiliary component 4 includes an extension plate 41, which is welded to one side of the blade plate 2. Pins 42 are symmetrically inserted into the inner wall of the extension plate 41. One end of the two pins 42 is symmetrically fixedly installed at the bottom of the mounting plate 7. By setting the extension plate 41, the two pins 42 are inserted into the inner wall of the extension plate 41, which can limit the extension plate 41 and connect the blade plate 2 and the mounting plate 7. This helps to prevent the blade plate 2 from separating from the fixed plate 1 from the side away from the retaining strip 31, thereby improving the stability of the connection between the blade plate 2 and the fixed plate 1. A rubber block 43 is fixedly installed at one end of the pin 42. One side of the rubber block 43 abuts against one side of the extension plate 41. By setting the rubber block 43, after the pin 42 is inserted into the inner wall of the extension plate 41, the extension plate 41 will squeeze the rubber block 43. The good deformation of the rubber block 43 can be used to assist in fixing the pin 42 and the extension plate 41.

[0032] Reference Figure 1 and Figure 2 As shown, the paper cutting mechanism includes a paper cutter body 5, a blade holder 6, and a mounting plate 7. The blade is located on one side of the mounting plate 7. The blade holder 6 is slidably located on the top of the paper cutter body 5. The mounting plate 7 is slidably installed inside the blade holder 6. An electric telescopic rod is installed inside the blade holder 6 (this specifically refers to an electric paper cutter; if it were a hydraulic paper cutter, it would be a hydraulic rod). The electric telescopic rod can drive the blade connected to the mounting plate 7 to move downward, thereby driving the blade to cut the paper.

[0033] Working principle: Insert the retaining strip 31 into the inner wall of the fixing plate 1, and let the two pins 42 insert into the inner wall of the extension plate 41. The rubber block 43 squeezes the extension plate 41, and pulls the L-shaped plate 33 downward. The L-shaped plate 33 will pull the spring 36, causing the spring 36 to deform until one side of the L-shaped plate 33 abuts against one side of the blade plate 2. Then rotate the bolt 34 so that one end of the bolt 34 abuts against one side of the blade plate 2, which can fix the L-shaped plate 33 and prevent the L-shaped plate 33 from shifting. At the same time, the two bolts 34 can also assist the blade plate 2. The fixing function allows the two L-shaped plates 33 to limit the two ends of the blade plate 2, which helps prevent the blade plate 2 from detaching from the fixing plate 1. When the blade plate 2 needs to be replaced, first rotate the bolt 34 so that the bolt 34 is away from the blade plate 2. Then the spring 36 loses the external force restriction and will reset, which will drive the L-shaped plate 33 to reset, so that the L-shaped plate 33 is away from the blade plate 2. This pushes the blade plate 2, causing the locking strip 31 to disengage from the inner wall of the fixing plate 1 and the pin 42 to disengage from the inner wall of the extension plate 41, thus completing the quick disassembly of the blade plate 2.
