Description

Technical Field

[0001] This utility model relates to the field of plastic core cutting technology, and in particular to a modular plastic core cutting machine. Background Technology

[0002] Plastic roll cores are mainly used for winding lithium battery separators, PE protective films, automotive films, industrial tapes, aluminum foil, copper foil, etc., and are widely used in many industries. During the production and processing of plastic roll cores, in order to meet different usage requirements, a cutting machine is used to cut the plastic roll cores to obtain plastic roll cores that meet specific usage length requirements.

[0003] In current technology, the most commonly used cutting machines for cutting plastic cores involve placing the plastic core to be cut on a processing table and fixing it, then driving the blade to rotate and perform the cutting operation. However, a large amount of debris is generated during the cutting process of plastic cores, and some of the debris adheres to the blade surface. As the amount of debris adhering to the blade surface gradually increases, it will cause the blade to produce uneven cuts during cutting, thus affecting the cutting quality of the plastic core. Utility Model Content

[0004] Therefore, it is necessary to provide a modular plastic core cutting machine to address the problem that as the amount of debris attached to the blade surface gradually increases, it will cause uneven cuts during cutting, thus affecting the cutting quality of plastic cores.

[0005] Includes: a workbench, a fixing mechanism and a fixing frame installed on the top of the workbench, an installation groove opened on one side of the top of the workbench, a moving rod slidably connected to the bottom of the fixing frame, and a cutting machine body installed at the bottom of the moving rod; The cleaning mechanism includes a rectangular frame fixedly connected to the inner wall of the mounting slot. A through slot is provided on one side of the rectangular frame. Brush bristles are installed on both sides of the inner wall of the rectangular frame. Three dust collection frames are fixedly connected to the surface of the rectangular frame. A collection box is fixedly connected to the front end of the workbench. A fan is installed on one side of the collection box. A four-way pipe is connected to the other side of the collection box. The other three ends of the four-way pipe are respectively connected to the three dust collection frames.

[0006] In one embodiment, the cleaning mechanism further includes a squeezing rod fixedly connected to one side of the movable rod. A movable block is slidably connected to the inner top wall of the rectangular frame. A rectangular rod is fixedly connected to the bottom end of the movable block. A spring is fixedly connected between one side of the movable block and the inner wall of the rectangular frame. The end of the squeezing rod away from the movable rod is located on the same axis as the movable block. Under the action of the squeezing rod, the movable block, and the rectangular rod, the brush bristles are easily agitated after cleaning the debris attached to the cutting blade. This causes the debris attached to the brush bristles to fall off and be absorbed by the dust collection frame, preventing residual debris from adhering to the surface of the cutting blade again when the cutting blade performs another cutting operation. This ensures that the brush bristles remain clean when they first come into contact with the cutting blade.

[0007] In one embodiment, a second filter plate is fixedly connected to the inner wall of the collection box, and the second filter plate is inclined. This facilitates the interception of debris entering the collection box, preventing debris from entering the blower and ensuring the normal operation of the device.

[0008] In one embodiment, one side of the suction frame forms an angle with the vertical plane, and a first filter plate is fixedly connected to one side of the suction frame. This facilitates the interception of larger debris during the suction process, preventing larger debris from entering the four-way pipe and causing blockage, thereby ensuring the normal operation of the device.

[0009] In one embodiment, the rectangular rod is located on one side of the brush bristles, and a through groove is formed on one side of the rectangular rod. The through groove in the rectangular rod helps to ensure that the cutting machine body can pass through the rectangular rod normally.

[0010] In one embodiment, protective plates are fixedly connected to both sides of the movable block, and the top of the protective plates is flush with the inner top wall of the rectangular frame. This prevents debris from entering the movable groove and helps protect the spring.

[0011] In one embodiment, the inner walls of the rectangular rod form an angle with the vertical plane on both sides, and the inclined surface of the rectangular rod contacts the surface of the bristles. The inclined surfaces on both sides of the inner walls of the rectangular rod help reduce the resistance when the rectangular rod moves, and facilitate better agitation of the bristles by the rectangular rod.

[0012] In one embodiment, the inclined surface of the dust collection frame faces the brush bristles. This facilitates better entry of debris cleaned by the brush bristles into the dust collection frame. Beneficial effects

[0013] 1. In this solution, while the cutting machine body moves horizontally after cutting, the cleaning mechanism, with the action of the rectangular frame and the brushes on both sides of the inner wall of the rectangular frame, facilitates the simultaneous cleaning of the cutting blade. The interaction of the fan, four-way pipe, and dust collection frame further facilitates the simultaneous adsorption of debris from the cutting blade surface and the debris cleaned by the brushes, improving the cleaning effect of the brushes on the cutting blade. Furthermore, the action of the extrusion rod, moving block, and rectangular rod helps to agitate the brushes after cleaning the debris on the cutting blade, causing the debris attached to the brushes to fall off and be adsorbed by the dust collection frame. This prevents residual debris from re-attaching to the cutting blade surface during subsequent cutting operations, ensuring the cleaning effect of the brushes on the cutting blade and thus guaranteeing the cutting effect of the cutting blade and improving the cutting quality of the plastic core. 2. The first filter plate helps the dust collection frame intercept larger debris during the adsorption process, preventing larger debris from entering the four-way pipe and causing blockage, thus ensuring the normal operation of the device.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-6 This invention describes a modular plastic core cutting machine.

[0019] In one embodiment, a modular plastic core cutting machine includes: a workbench 100, a fixing mechanism 200 and a fixing frame 300 installed on the top of the workbench 100, an installation groove 110 opened on one side of the top of the workbench 100, a moving rod 400 slidably connected to the bottom of the fixing frame 300, and a cutting machine body 500 installed at the bottom of the moving rod 400. The cleaning mechanism 600 includes a rectangular frame 610 fixedly connected to the inner wall of the mounting groove 110. A through groove is provided on one side of the rectangular frame 610. Brush bristles 611 are installed on both sides of the inner wall of the rectangular frame 610. Three dust collection frames 620 are fixedly connected to the surface of the rectangular frame 610. A collection box 630 is fixedly connected to the front end of the workbench 100. A fan 640 is installed on one side of the collection box 630. A four-way pipe 631 is connected to the other side of the collection box 630. The other three ends of the four-way pipe 631 are respectively connected to the three dust collection frames 620.

[0020] It should be noted that the cutting machine body 500 includes a motor and a cutting blade. The motor is fixedly connected to the bottom end of the moving rod 400, and one end of the cutting blade is fixedly connected to the output shaft of the motor. The motor is started by the controller, and the output shaft of the motor will drive the cutting blade to rotate to perform the cutting operation. The fixing mechanism 200 includes a limiting plate, an electric push rod, and a fixing plate. The limiting plate and the electric push rod are installed on the top of the worktable 100 by bolts. The fixing plate is fixedly connected to the telescopic end of the electric push rod. When cutting the plastic core, the plastic core is placed between the fixing plate and the limiting plate, and the electric push rod is started by the controller. The telescopic end of the electric push rod will push the fixing plate to move and press the plastic core against it, thereby fixing the plastic core between the limiting plate and the fixing plate. The limiting plate has a scale line on one side and a baffle is slidably connected to the limiting plate on the other side. When cutting the plastic core, the baffle is moved according to the required cutting length of the plastic core so that the baffle is aligned with the corresponding scale line and one end of the plastic core is pressed against the baffle. At this time, the cutting position of the plastic core and the cutting blade are on the same axis.

[0021] A placement rack is bolted to one side of the workbench 100. When cutting the plastic core, the plastic core can be placed on the placement rack and supported by the placement rack. A motor is fixedly connected to one side of the fixed frame 300, and a lead screw is rotatably connected to the inner wall of the fixed frame 300. A slider is threaded onto the surface of the lead screw, and one end of the lead screw is fixedly connected to the output shaft of the motor. The top end of the moving rod 400 is fixedly connected to the bottom end of the slider. When the motor is started by the controller, the output shaft of the motor will drive the lead screw to rotate, thereby driving the slider to move the moving rod 400 synchronously. A limit rod is fixedly connected to the inner wall of the fixed frame 300, and the inner wall of the moving rod 400 is slidably connected to the surface of the limit rod. The limit rod will limit the movement path of the moving rod 400. In this embodiment, the cutting blade is located on the central axis of the mounting groove 110 and the rectangular frame 610, and the lower end of the surface of the cutting blade extends through the inner side of the mounting groove 110. The distance between the inner top wall and the inner bottom wall of the rectangular frame 610 is greater than the diameter of the cutting blade. The motor in the cutting machine body 500 and the through groove opened in the rectangular frame 610 are located on the same axis. When the cutting machine body 500 moves horizontally, the cutting blade will pass through the rectangular frame 610, and the motor can pass through the through groove, thereby ensuring that the cutting machine body 500 can move normally through the rectangular frame 610. When the cutting blade passes through the rectangular frame 610, the bristles 611 on both sides of the inner wall of the rectangular frame 610 will contact the two ends of the cutting blade. The bristles 611 can be deformed. When the moving rod 400 drives the cutting machine body 500 through the rectangular frame 610, the moving rod 400 and the rectangular frame 610 do not affect each other.

[0022] One of the three dust collection frames 620 and the other two dust collection frames 620 are located on both sides of the surface of the rectangular frame 610, respectively. The other two dust collection frames 620 are installed on the surface of the rectangular frame 610 with through slots to ensure that the cutting machine body 500 can pass smoothly through the dust collection frames 620.

[0023] like Figure 3 and Figure 6 As shown, the cleaning mechanism 600 also includes a pressing rod 650 fixedly connected to one side of the moving rod 400. A moving block 612 is slidably connected to the inner top wall of the rectangular frame 610. A rectangular rod 613 is fixedly connected to the bottom end of the moving block 612. A spring 614 is fixedly connected between one side of the moving block 612 and the inner wall of the rectangular frame 610. The end of the pressing rod 650 away from the moving rod 400 is located on the same axis as the moving block 612. The rectangular rod 613 is located on one side of the bristles 611, and a through groove is provided on one side of the rectangular rod 613. The two sides of the inner wall of the rectangular rod 613 form an angle with the vertical plane, and the inclined surface of the rectangular rod 613 contacts the surface of the bristles 611.

[0024] In this embodiment, when the cutting machine body 500 passes through the rectangular frame 610, the motor in the cutting machine body 500 will pass through the through slot of the rectangular rod 613, and the cutting blade and the rectangular rod 613 will not affect each other. In the initial state, the rectangular rod 613 is close to the dust collection frame 620, and the spring 614 is in the released state. The pressing rod 650 and the moving block 612 are on the same horizontal plane. When the cutting machine body 500 moves and performs cutting, the pressing rod 650 will move away from the moving block 612. When the cutting machine body 500 finishes cutting and moves towards the rectangular frame 610, and the cutting blade completely penetrates the rectangular frame 610, the end of the pressing rod 650 away from the moving rod 400 will contact one side of the moving block 612 and drive the moving rod 400 to drive the cutting machine body 500 to continue moving. At this time, the pressing rod 650 will push the moving block 612 to drive the rectangular rod 613 to move away from the dust collection frame 620, and the spring 614 will be compressed. When the cutting machine body 500 moves again to perform cutting operations, the pressing rod 650 will release the pressure on the moving block 612, and the spring 614 will lose its pressing force, which will drive the moving block 612 and the rectangular rod 613 to reset.

[0025] like Figure 3 As shown, a second filter plate 632 is fixedly connected to the inner wall of the collection box 630, and the second filter plate 632 is inclined.

[0026] In this embodiment, during operation, the second filter plate 632 intercepts debris entering the collection box 630. A removable cover is bolted to one side of the collection box 630. When it is necessary to clean the debris in the collection box 630, the cover can be opened for cleaning.

[0027] like Figure 5 As shown, one side of the dust collection frame 620 forms an angle with the vertical plane, and a first filter plate 621 is fixedly connected to one side of the dust collection frame 620.

[0028] In this embodiment, during the process of the dust collection frame 620 adsorbing the debris cleaned by the brush bristles 611 by starting the fan 640 through the controller, larger debris will be intercepted by the first filter plate 621. When the fan 640 is turned off, the debris intercepted by the first filter plate 621 will fall off.

[0029] like Figure 6 As shown, protective plates 615 are fixedly connected to both sides of the movable block 612, and the top of the protective plate 615 is attached to the inner top wall of the rectangular frame 610.

[0030] In this embodiment, the inner top wall of the rectangular frame 610 is provided with a moving groove that matches the moving block 612, the spring 614 is disposed in the moving groove, and the protective plate 615 protects the moving groove.

[0031] like Figure 4 As shown, the inclined surface of the dust collection frame 620 faces the bristles 611. This allows the debris cleaned by the bristles 611 to enter the dust collection frame 620 more effectively during the suction process.

[0032] Working principle: Place the plastic core to be cut on the worktable 100 and fix it with the fixing mechanism 200 so that the cutting point of the plastic core and the cutting blade are on the same axis. After fixing, drive the cutting blade in the cutting machine body 500 to rotate, and at the same time drive the cutting machine body 500 to move towards the plastic core through the moving rod 400. During the movement, the cutting machine body 500 will complete the cutting operation of the plastic core.

[0033] After the cutting machine body 500 finishes cutting the plastic roll core, the cutting blade stops rotating, and the cutting machine body 500 is moved towards the rectangular frame 610 by the moving rod 400. During the movement, the cutting blade enters the rectangular frame 610. At this time, the bristles 611 will contact both ends of the cutting blade, and as the cutting blade continues to move, the debris attached to the cutting blade will be cleaned by the bristles 611. At the same time, the controller starts the fan 640 to run, and the fan 640 discharges the air in the collection box 630, creating a negative pressure in the collection box 630. At this time, the four-way pipe 631... The other three ends draw in external air, so that the three suction frames 620 simultaneously absorb the debris cleaned by the bristles 611 while the bristles 611 are cleaning. When the cutting blade completely penetrates the rectangular frame 610 and continues to move, the squeezing rod 650 pushes the moving block 612 to move the rectangular rod 613 away from the suction frame 620. During the movement, the rectangular rod 613 causes the bristles 611 to deform and vibrate, causing the debris attached to the bristles 611 to fall off and be sucked up by the suction frame 620. The absorbed debris enters the collection box 630 through the four-way pipe 631 for collection.

[0034] It should be noted that the motors and electric linear actuators mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the motors and electric linear actuators can be powered by built-in power supplies or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
