Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a cutting machine with easily replaceable blades. Background Technology

[0002] A cutting machine is a device that can cut objects. It is widely used in the textile industry, mainly for cutting materials such as cotton, wool, linen, silk, chemical fibers, and leather.

[0003] According to a cutting machine with easily replaceable cutting blades (Announcement No.: CN218404819U) published in the above application, the installation can be completed by inserting the positioning block into the positioning hole and rotating the bolt. The positioning block and the slot can play a guiding role, thereby facilitating the installation and removal of the cutting blade and making it easier to maintain it later.

[0004] However, in actual use, when the blade is damaged, the blade needs to be aligned with the positioning hole. This process requires the user to hold the blade continuously, which poses a risk of cut to the user. In order to ensure user safety, the speed of blade replacement is reduced, thus reducing the efficiency of the cutting machine. Therefore, we propose a cutting machine that facilitates blade replacement. Utility Model Content

[0005] The purpose of this invention is to provide a cutting machine with easily replaceable blades, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting machine with convenient blade replacement, comprising a base, a cutting groove formed on the outer wall of the base, a vertical plate fixedly connected to the outer wall of the base, a pressing rod fixedly connected to the outer wall of the vertical plate, a fixed housing fixedly connected to the output end of the pressing rod, a blade slidably connected to the lower outer wall of the fixed housing, and a replacement assembly provided inside the fixed housing, the replacement assembly comprising: The slot is located on the upper outer wall of the fixed shell. A push block is slidably connected through the inner wall of the fixed shell. A return spring is fixedly connected to the outer wall of the push block. A push plate is fixedly connected to the upper outer wall of the push block. A connecting plate is fixedly connected to the outer wall of the push block. A pressure block is fixedly connected to the end of the connecting plate away from the push block. A fixing plate is fixedly connected to the upper outer wall of the blade. A locking block is slidably connected to the inner wall of the base.

[0007] Preferably, the interior of the fixed shell is provided with an unlocking component, which includes a pull plate that is slidably connected to the outer wall of the fixed shell. A transmission plate is fixedly connected to the outer wall of the pull plate, and hinge plates are hinged to both ends of the transmission plate. A locking block is hinged to the end of the hinge plate away from the transmission plate. A compression spring is fixedly connected to the outer wall of the pull plate, so that after the pull plate is pulled, the locking block can be moved away from the blade, thereby disengaging the locking block from the blade.

[0008] Preferably, the end of the compression spring away from the pull plate is fixedly connected to the inner wall of the fixed shell, the end of the pull plate near the outer wall of the fixed shell is provided with a compression groove, the outer wall of the locking block is provided with a locking groove, and the cutting end of the blade is locked with the locking block. When the pull plate is pulled, the pull plate drives the transmission plate to move and causes the hinge plate to rotate. The rotation of the hinge plate drives the locking block to move and causes the locking block to disengage from the fixed plate, so that there is no obstruction below the fixed plate.

[0009] Preferably, the size of the slot is the same as the size of the blade, and the end of the return spring away from the push block is fixedly connected to the inner wall of the fixed shell, so that when the blade is undamaged, a spare blade can be placed in the slot, and when the currently used blade is damaged, the damaged blade can be taken out, and then the push plate can be pulled to immediately replace the intact blade in the slot with the designated position, without the user needing to contact the blade during the replacement process.

[0010] Preferably, the lower outer wall of the fixed shell is provided with a cutting groove, the blade passes through the cutting groove and is slidably connected to the inner wall of the cutting groove, and the locking block passes through the inner wall of the cutting groove and is slidably connected to the inner wall of the cutting groove, so that the tip of the blade can extend out of the fixed shell, and when the fixed shell is moved down by the pressing rod, the blade can cut the material.

[0011] Preferably, a limiting plate is fixedly connected to the lower outer wall of the pull plate, one end of the compression spring is fixedly connected to the limiting plate, and the other end of the compression spring is fixedly connected to the inner wall of the fixed shell. When the pull plate loses its tension, the compression spring causes the pull plate to drive the transmission plate to reset, thereby causing the hinge plate to drive the locking block to reset. At this time, the fixing plate of the blade presses on the outer wall of the locking block, and the locking block blocks the fixing plate so that the blade cannot move down, so that the blade can be fixed in the fixed shell.

[0012] Preferably, the upper outer wall of the fixing plate is flush with the upper outer wall of the blade groove, and the lower outer wall of the pressure block is in contact with the upper outer wall of the fixing plate. The return spring causes the push block to drive the pressure block to return to its original position through the connecting plate, so that the pressure block and the locking block cooperate to clamp the fixing plate and fix the blade more firmly in the fixing shell.

[0013] Compared with the prior art, this utility model provides a cutting machine with convenient blade replacement, which has the following beneficial effects: 1. This easy-to-change cutting machine allows for blade replacement. By placing a spare blade in the slot, after the damaged blade is removed, the push plate can be pushed, causing the push block to move the intact blade. Simultaneously, the connecting plate can drive the pressure block to move, allowing the intact blade to be moved above the blade slot for replacement. At this point, the push plate can be released, and the pressure block is reset by the return spring, fixing the blade in the fixed housing. This eliminates the need for the user to contact the blade during replacement, resulting in faster blade replacement and higher efficiency.

[0014] 2. This cutting machine with easy blade replacement allows the blade to be easily removed from the fixed housing when the blade is damaged during use. Pulling the pull plate moves the transmission plate, causing the hinge plate to rotate. The rotation of the hinge plate moves the locking block, causing it to disengage from the fixed plate.

Detailed Implementation

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a cutting machine with convenient blade replacement, including a base 1, a cutting groove 2 on the outer wall of the base 1, a vertical plate 3 fixedly connected to the outer wall of the base 1, a pressing rod 4 fixedly connected to the outer wall of the vertical plate 3, a fixed housing 5 fixedly connected to the output end of the pressing rod 4, a blade 6 slidably connected to the lower outer wall of the fixed housing 5, and a replacement component 7 provided inside the fixed housing 5. The replacement component 7 includes a slot 71, a push block 72, a return spring 73, a push plate 74, a connecting plate 75, a pressure block 76, a fixing plate 77, and a locking block 78.

[0018] In one embodiment of the present invention, the slot 71 is formed on the upper outer wall of the fixed shell 5, the inner wall of the fixed shell 5 is slidably connected to the push block 72, the outer wall of the push block 72 is fixedly connected to the return spring 73, and the upper outer wall of the push block 72 is fixedly connected to the push plate 74.

[0019] In one embodiment of the present invention, a connecting plate 75 is fixedly connected to the outer wall of a push block 72, a pressure block 76 is fixedly connected to the end of the connecting plate 75 away from the push block 72, a fixing plate 77 is fixedly connected to the upper outer wall of the blade 6, and a locking block 78 is slidably connected to the inner wall of the base 1.

[0020] In addition, an unlocking component 8 is provided inside the fixed housing 5. The unlocking component 8 includes a pull plate 81, which is slidably connected to the outer wall of the fixed housing 5. A transmission plate 82 is fixedly connected to the outer wall of the pull plate 81. Both ends of the transmission plate 82 are hinged to hinge plates 83. A locking block 78 is hinged to the end of the hinge plate 83 away from the transmission plate 82. A compression spring 84 is fixedly connected to the outer wall of the pull plate 81. When the pull plate 81 is pulled, the locking block 78 can be moved away from the blade 6, so that the locking block 78 is disengaged from the blade 6, thereby allowing the blade 6 to be disengaged from the fixed housing 5 for easy replacement.

[0021] In an embodiment of this utility model, the end of the compression spring 84 away from the pull plate 81 is fixedly connected to the inner wall of the fixed shell 5. The end of the pull plate 81 near the outer wall of the fixed shell 5 is provided with a compression groove. The outer wall of the locking block 78 is provided with a locking groove. The cutting end of the blade 6 is locked with the locking block 78. When the pull plate 81 is pulled, the pull plate 81 drives the transmission plate 82 to move and the hinge plate 83 to rotate. The rotation of the hinge plate 83 drives the locking block 78 to move and disengage the locking block 78 from the fixed plate 77, so that there is no obstruction below the fixed plate 77, thereby allowing the blade 6 to be removed from the fixed shell 5.

[0022] In this embodiment of the invention, the size of the slot 71 is the same as the size of the blade 6. The end of the return spring 73 away from the push block 72 is fixedly connected to the inner wall of the fixed shell 5, so that when the blade 6 is undamaged, a spare blade 6 can be placed in the slot 71. When the currently used blade 6 is damaged, the damaged blade 6 can be taken out, and then the push plate 74 is pulled to immediately replace the intact blade 6 in the slot 71 with the designated position. During the replacement, the user does not need to contact the blade 6, so the replacement speed is faster and the cutting machine is more efficient.

[0023] In an embodiment of this utility model, a cutting groove is provided on the lower outer wall of the fixed shell 5. The blade 6 passes through the cutting groove and is slidably connected to the inner wall of the cutting groove. The locking block 78 passes through the inner wall of the cutting groove and is slidably connected to the inner wall of the cutting groove, so that the tip of the blade 6 can extend out of the fixed shell 5. When the fixed shell 5 is moved down by the pressing rod 4, the blade 6 can fit with the cutting groove 2 and the material can be completely cut.

[0024] In this embodiment of the utility model, a limiting plate is fixedly connected to the lower outer wall of the pull plate 81, one end of the compression spring 84 is fixedly connected to the limiting plate, and the other end of the compression spring 84 is fixedly connected to the inner wall of the fixed shell 5. When the pull plate 81 loses its tension, the compression spring 84 causes the pull plate 81 to drive the transmission plate 82 to reset, thereby causing the hinge plate 83 to drive the locking block 78 to reset. At this time, the fixing plate 77 of the blade 6 presses on the outer wall of the locking block 78, and the locking block 78 blocks the fixing plate 77 so that the blade 6 cannot move down, so that the blade 6 can be fixed in the fixed shell 5, thereby enabling the blade 6 to stably cut the material.

[0025] In this embodiment of the utility model, the upper outer wall of the fixing plate 77 is flush with the upper outer wall of the blade groove, the lower outer wall of the pressure block 76 is in contact with the upper outer wall of the fixing plate 77, and the reset spring 73 causes the push block 72 to drive the pressure block 76 to reset through the connecting plate 75, so that the pressure block 76 and the locking block 78 cooperate to clamp the fixing plate 77, making the blade 6 more firmly fixed in the fixing shell 5, thereby improving the cutting effect of the blade 6.

[0026] In this invention, during use, the material is placed on the base 1, and the pressing rod 4 drives the blade 6 downward, allowing the blade 6 to fit against the cutting groove 2 while completely cutting the material. When the blade 6 is undamaged, a spare blade 6 can be placed in the slot 71. When the blade 6 in use is damaged, the pull plate 81 can be pulled, causing the pull plate 81 to move the transmission plate 82, which in turn rotates the hinge plate 83. The rotation of the hinge plate 83 causes the locking block 78 to move, disengaging the locking block 78 from the fixing plate 77, thus removing any obstruction below the fixing plate 77 and allowing the blade 6 to be easily removed from the fixing shell 5. After the damaged blade 6 is removed... Afterwards, release the pull plate 81 to allow the locking block 78 to reset via the compression spring 84. At this time, the push plate 74 can be pushed to allow the push block 72 to move the intact blade 6. Simultaneously, the connecting plate 75 can drive the pressure block 76 to move, allowing the intact blade 6 to move above the blade groove and fall below the blade groove, exposing the blade 6 to the fixing shell 5. Then, release the push plate 74, and the pressure block 76 will reset via the reset spring 73, allowing the locking block 78 to clamp the fixing plate 77, making the blade 6 more securely fixed within the fixing shell 5. During the replacement process, the user does not need to contact the blade 6, making the cutting machine replacement faster and thus increasing the efficiency of the cutting machine.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
