[0002] With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing, as are the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions.

[0003] With the diversification of production demands, cutting equipment needs to frequently switch between different specifications of cutting tools to adapt to different processing tasks. Currently, most cutting equipment on the market has a fixed tool holder structure, requiring disassembly and reinstallation of the tool holder when switching tools. This operation is cumbersome and time-consuming, seriously affecting production efficiency. Utility Model Content

Each quick-release component includes a semi-circular ring, one of which has its outer wall slidably connected to the outer wall of a fixed block, and another of which has its inner wall fixedly connected to a fixed block. A pull rod is slidably connected to the inner wall of the fixed block, a first spring is sleeved on the outer wall of the pull rod, a connecting block is fixedly connected to one end of the pull rod, a rotating shaft is rotatably connected to the inner wall of the connecting block, connecting rods are slidably connected to the outer walls of multiple rotating shafts, and sliders are slidably connected to the outer walls of the connecting rods.

[0006] The above technical solution involves storing spare blades, different types of blades, and damaged blades in multiple storage boxes. After the blades have finished cutting the workpiece, the cutting fragments are collected in a collection pool.

A lead screw is fixedly connected to the output end of the second motor. A plurality of limit blocks are slidably connected to the outer wall of the lead screw.

The outer wall of the lead screw is rotatably connected to the inner wall of the base.

[0008] The above technical solution involves limiting the motor and lead screw via the base, starting the second motor to provide power to the lead screw, then the lead screw drives multiple limit blocks to slide, then the multiple limit blocks limit the workpiece to be cut, and finally the electric pressure plate presses down and fixes the workpiece to be cut.

[0010] The above technical solution involves starting the first motor to provide power to the output shaft, which then drives the first pulley to rotate. The base limits the transmission shaft, and the transmission shaft limits the second pulley.

[0011] As a further description of the above technical solution: Preferably, one end of the drive shaft is fixedly connected to a roller, and the outer wall of the roller is rotatably connected to the surface of the base.

[0012] The above technical solution involves using a drive shaft to rotate a roller on the surface of a base, at which point the base restricts the position of the roller.

[0013] As a further description of the above technical solution: Preferably, the outer walls of the first and second pulleys are fitted with belts, the outer wall of the output shaft rotates on the inner wall of the base, and one end of the output shaft is fixedly connected to one side of the roller.

[0014] The above technical solution connects the first pulley and the second pulley via a belt. When the first pulley rotates, it drives the second pulley. The base limits the output shaft, and when the output shaft rotates, it drives the roller to rotate.

[0016] The above technical solution involves limiting the slider using a semicircular ring and a fixed block, then limiting the connecting block and connecting rod using the fixed block, and finally using a rotating shaft to drive the slider to slide along the inner wall of the semicircular ring and the fixed block.

[0017] As a further description of the above technical solution: Preferably, the plurality of quick-change components include a blade holder, the outer wall of the plurality of blade holders is slidably connected to the inner wall of the semicircular ring, the surface of the plurality of semicircular rings is provided with a slot, the inner wall of the plurality of blade holders is slidably connected to a button, one end of the plurality of buttons is fixedly connected to a shaped block, the inner wall of the plurality of blade holders is provided with a second spring, and the outer wall of the plurality of blade holders is fixedly connected to a blade.

[0018] The above technical solution uses a groove on the surface of a semi-circular ring to limit the tool holder, which facilitates later installation and reduces installation difficulty. The tool holder limits the button, and then the button drives the irregular block to slide. Next, the tool holder limits the second spring and the blade.

[0019] As a further description of the above technical solution: Preferably, a plurality of the second springs are disposed on one side of the irregularly shaped block, and the outer walls of the plurality of irregularly shaped blocks are slidably connected to the inner walls of the semicircular ring and the tool holder.

[0020] The above technical solution involves limiting the irregular block using a semi-circular ring and a tool holder, allowing the irregular block to slide on the inner wall of the tool holder and the semi-circular ring, thus causing the irregular block to compress the second spring.

[0021] This utility model has the following beneficial effects: 1. In this utility model, by pulling the pull rod, the connecting block is slid and squeezes the first spring. Then, the rotating shaft and connecting rod drive the slider to slide from the inner wall of the semi-circular ring to the inner wall of the fixed block, thereby separating the two semi-circular rings and achieving the function of quick disassembly, which is convenient for maintenance and replacement. By pressing the button, the irregular block is squeezed by the second spring, allowing the irregular block to disengage from the slot, thereby realizing the quick replacement of the tool holder and the blade.

[0022] 2. In this utility model, the second motor drives the lead screw to rotate, thereby causing multiple limiting blocks to slide on the outer wall of the lead screw. After adjusting to a suitable position according to the width of the object to be cut, the electric pressure plate is activated to fix the object to be cut, which prevents deviation and avoids affecting the subsequent cutting effect. The first motor is activated to drive the first pulley to rotate through the output shaft, and then the belt drives the second pulley to rotate, thereby driving the roller to rotate and conveying the object to be cut. Then, the output shaft drives the roller and the semi-circular ring to rotate together, thereby driving multiple blades to cut the object to be cut. Attached Figure Description

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a cutting device that facilitates quick blade switching, comprising a base 1, a storage box 2 and a collection pool 3 fixedly connected to the outer wall of the base 1, a roller 5 rotatably connected to the outer wall of the base 1, a guide groove formed on the surface of the outer wall of the roller 5, and multiple quick-release components 6 slidably connected to the inner wall of the roller 5 through the guide groove. Each quick-release component 6 includes a semi-circular ring 601, the outer wall of one semi-circular ring 601 slidably connected to the outer wall of a fixing block 602, and the inner wall of one semi-circular ring 601 fixedly connected to the fixing block 602. A pull rod 603 is slidably connected to the inner wall of the fixing block 602, and a first spring 604 is sleeved on the outer wall of the pull rod 603. One end of the base 3 is fixedly connected to a connecting block 605. The inner wall of the connecting block 605 is rotatably connected to a rotating shaft 607. The outer walls of multiple rotating shafts 607 are slidably connected to connecting rods 606. The outer walls of the connecting rods 606 are slidably connected to sliders 608. The inner wall of the semi-circular ring 601 is provided with a quick-change component 7. The inner wall of the base 1 is provided with a transmission component 8 and an adjustment component 9. The outer wall of the connecting block 605 is slidably connected to the inner wall of the fixed block 602. The outer wall of the connecting rod 606 is slidably connected to the inner wall of the fixed block 602. The outer wall of one of the rotating shafts 607 is rotatably connected to the inner wall of the slider 608. The outer wall of the slider 608 is slidably connected to the inner walls of the semi-circular ring 601 and the fixed block 602. Specifically, firstly, pull the lever 603 of the quick-release assembly 6. The lever 603 will cause the connecting block 605 to slide against the inner wall of the fixing block 602. At this time, the connecting block 605 will compress the first spring 604. When the connecting block 605 slides, it will drive the rotating shaft 607 to rotate. Then, the rotating shaft 607 will drive the connecting rod 606 to slide against the inner wall of the fixing block 602. In this way, the connecting rod 606 will drive the slider 608 to slide from the inner wall of one of the semicircular rings 601 to the inner wall of the fixing block 602 through one of the rotating shafts 607, thereby unlocking one of the semicircular rings 601 from the fixing block 602, achieving the effect of quick disassembly, which is convenient for maintenance and replacement. Then, pull the lever 603 to slide the slider 608 to the inner wall of the fixed block 602. According to the guide groove on the surface of the roller 5, multiple semicircular rings 601 are fastened to the roller 5. Then, release the lever 603. Under the rebound force of the first spring 604, the slider 608 is driven to slide from the inner wall of the fixed block 602 to the inner wall of the semicircular ring 601 and is locked in the inner wall of the semicircular ring 601, thereby realizing the function of quick installation. The first motor 801 drives the roller 4 and the roller 5 to rotate on the surface of the base 1. The roller 4 conveys and limits the object to be cut, and the roller 5 drives multiple blades 702 to cut the object to be cut. Then, the collection pool 3 collects the cutting fragments.

[0027] Reference Figure 6 , Figure 7 and Figure 8 The adjustment component 9 includes a second motor 901, which is fixedly connected to the inner wall of the base 1. The output end of the second motor 901 is fixedly connected to a lead screw 902. Multiple limit blocks 903 are slidably connected to the outer wall of the lead screw 902. An electric pressure plate 904 is provided on the inner wall of the limit block 903. The outer wall of the electric pressure plate 904 is slidably connected to the inner wall of the limit block 903. The outer wall of the lead screw 902 is rotatably connected to the inner wall of the base 1. Specifically, the second motor 901 of the start adjustment component 9 drives the lead screw 902 to rotate. When the lead screw 902 rotates, it will drive multiple limit blocks 903 to slide on the outer wall of the lead screw 902. The appropriate position can be adjusted according to the width of the object to be cut. Then, the electric pressure plate 904 is started to fix the object to be cut, preventing the position of the object to be cut from shifting and affecting the subsequent cutting effect.

[0028] Reference Figure 7 and Figure 8The transmission assembly 8 includes a first motor 801, which is fixedly connected to the inner wall of the base 1. The output end of the first motor 801 is fixedly connected to an output shaft 802, and the outer wall of the output shaft 802 is fixedly connected to a first pulley 803. The inner wall of the base 1 is rotatably connected to a transmission shaft 805, and the outer wall of the transmission shaft 805 is fixedly connected to a second pulley 804. One end of the transmission shaft 805 is fixedly connected to a roller 4, and the outer wall of the roller 4 is rotatably connected to the surface of the base 1. Belts are fitted on the outer walls of the first pulley 803 and the second pulley 804. The outer wall of the output shaft 802 rotates on the inner wall of the base 1, and one end of the output shaft 802 is fixedly connected to one side of the roller 5. Specifically, the first motor 801 of the transmission assembly 8 is started, which drives the output shaft 802 to rotate. When the output shaft 802 rotates, it drives the first pulley 803 to rotate. At the same time, the output shaft 802 also drives the roller 5 to rotate on the surface of the base 1, thereby driving the blade 702 to cut the object to be cut. The outer walls of the first pulley 803 and the second pulley 804 are fitted with belts. Through the belt, the first pulley 803 drives the second pulley 804 to rotate together. When the second pulley 804 rotates, it drives the transmission shaft 805 to rotate on the inner wall of the base 1, thereby driving the roller 4 to rotate on the surface of the base 1, and then the roller 4 pushes the object to be cut.

[0029] Reference Figure 1 , Figure 4 and Figure 5 The quick-change assembly 7 includes a tool holder 701. The outer walls of multiple tool holders 701 are slidably connected to the inner wall of a semi-circular ring 601. The surfaces of the multiple semi-circular rings 601 are provided with slots. Buttons 703 are slidably connected to the inner walls of the multiple tool holders 701. One end of the multiple buttons 703 is fixedly connected to a shaped block 704. Second springs 705 are provided on the inner walls of the multiple tool holders 701. Blades 702 are fixedly connected to the outer walls of the multiple tool holders 701. Multiple second springs 705 are provided on one side of the shaped block 704. The outer walls of the multiple shaped blocks 704 are slidably connected to the semi-circular ring 601 and the inner walls of the tool holders 701. Specifically, pressing button 703 of quick-change component 7 causes button 703 to slide on the inner wall of tool holder 701, and simultaneously causes the shaped block 704 to slide on the inner walls of tool holder 701 and semi-circular ring 601. Then, the shaped block 704 will compress the second spring 705, thus unlocking the connection between tool holder 701 and semi-circular ring 601, quickly separating tool holder 701 and blade 702 from semi-circular ring 601. This allows for quick replacement of worn blade 702 and different types of blade 702. After opening storage box 2 and selecting the appropriate blade 702, press multiple buttons 703, align tool holder 701 with the slot on semi-circular ring 601, and release button 703. Under the rebound force of the second spring 705, the shaped block 704 slides and engages in the slot of semi-circular ring 601, realizing the function of quick blade replacement 702.

[0030] Working principle: When using this utility model, the second motor 901 is first started to drive the lead screw 902 to rotate. When multiple lead screws 902 rotate, they will drive multiple limit blocks 903 to slide on the outer wall of the lead screw 902. After adjusting to the width suitable for the object to be cut, the electric pressure plate 904 is started to fix the object to be cut and limit the object to be cut to prevent it from deviating and affecting the cutting effect. Then, the first motor 801 is started to drive the first pulley 803 to rotate through the output shaft 802. The outer walls of the first pulley 803 and the second pulley 804 are fitted with belts. The first pulley 803 drives the second pulley 804 to rotate together through the belt. The second pulley 804 is limited by the transmission shaft 805. When the second pulley 804 rotates, it will drive the roller 4 to rotate together, pushing the object to be cut forward.

[0031] When the object to be cut is conveyed to the quick-release assembly 6, multiple blades 702 cut the object. The cut fragments are then collected by the collection pool 3. Pulling the lever 603 of the quick-release assembly 6 causes the connecting block 605 to slide and compress the first spring 604. When the connecting block 605 slides, it drives the rotating shaft 607 to rotate. Then, the rotating shaft 607 drives the connecting rod 606 to rotate. When the connecting rod 606 rotates, one of the rotating shafts 607 drives the slider 608 to slide from the inner wall of the semicircular ring 601 to the inner wall of the fixing block 602, unlocking the semicircular ring 601 from the fixing block 602. This allows the multiple semicircular rings 601 to separate, realizing the quick-release function and facilitating replacement and maintenance.

[0032] This invention utilizes multiple buttons 703 of the quick-change component 7 to slide the irregularly shaped block 704 against the inner wall of the semi-circular ring 601 and the blade holder 701, thereby compressing the second spring 705. This unlocks the semi-circular ring 601, achieving a quick separation effect. This facilitates the individual replacement of worn blades 702 and different types of blades 702. After opening the storage box 2 and selecting the appropriate blade 702, pressing multiple buttons 703 aligns the blade holder 701 with the slot on the semi-circular ring 601. Releasing the buttons 703 causes the irregularly shaped block 704 to slide and engage in the slot of the semi-circular ring 601 under the rebound force of the second spring 705, thus achieving the function of quick blade replacement 702.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
