Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for manufacturing plastic products. Background Technology

[0002] In the field of plastic product manufacturing, cutting equipment is a specialized device used to precisely separate plastic raw materials (such as sheets, pipes, profiles, and molded parts) or intermediate / finished parts according to preset dimensions and shapes. Its core function is to ensure the final dimensional accuracy and edge quality of plastic products, adapting them to subsequent assembly or finished product requirements. Its design needs to take into account the characteristics of plastic materials (such as hardness, toughness, and melting point; for example, PVC is hard and brittle, PE is soft and tough, and ABS is of medium hardness), product form (sheets / pipes / films), and cutting precision requirements.

[0003] In existing technologies, a large amount of irregularly shaped waste is inevitably generated during the cutting of plastic products. If this waste is scattered randomly on the workbench, it will not only occupy the limited operating space and cause the work area to become messy and crowded, but also directly interfere with the normal cutting process and seriously reduce the overall work efficiency. However, when collecting waste, it is difficult to effectively classify it due to the large differences in the size of the waste. It is impossible to distinguish and collect large block waste from small powdery waste, which increases the difficulty of subsequent waste treatment and is not conducive to resource recycling. When collecting powdery waste with a fan, the matching filter plate is usually fixed. Over time, powdery waste is easily adsorbed on the surface of the filter plate and causes blockage. This will not only lead to a significant decrease in the exhaust efficiency of the fan, but also cause equipment overload due to poor airflow, eventually damaging the fan and increasing production and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for manufacturing plastic products, in order to solve the problems mentioned in the background art, which are that a large amount of irregular waste is generated during the cutting of plastic products. The waste is scattered randomly on the workbench, which will occupy space, disrupt the cutting process, and significantly reduce the efficiency of operation. During collection, due to the large difference in the size of the waste, it is difficult to distinguish between blocky and powdery waste, which increases the difficulty of subsequent processing and is not conducive to resource recycling. Even if a fan is used to collect powdery waste, the matching fixed filter plate is easily blocked by powder adsorption, which not only reduces the ventilation efficiency, but also causes equipment overload, ultimately leading to damage to the fan and increased maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for manufacturing plastic products, including a workbench, a cutting component mounted on the workbench, a dust collection component mounted on the workbench, a cleaning component mounted on the dust collection component, a first waste collection frame detachably mounted on the workbench, and a discharge chute opened on the workbench, the discharge chute being located above the first waste collection frame. A first drive unit is mounted on the workbench, and two sets of cleaning modules are slidably connected to the workbench. The cleaning modules are mounted on the output end of the first drive unit, which is used to drive the cleaning modules to move closer or further apart from each other.

[0006] According to the preferred embodiment of this technical solution, the first drive unit includes a first motor fixedly connected to one side of the workbench and a bidirectional threaded rod rotatably connected to the workbench. The bidirectional threaded rod is fixedly connected to the output end of the first motor, and the first cleaning frame is threadedly connected to the bidirectional threaded rod.

[0007] According to the preferred embodiment of this technical solution, the second drive unit includes a second motor fixedly connected to the first sweeping frame, the second sweeping frame fixedly connected to the output end of the second motor, and the second motor being disposed inside the protective frame.

[0008] Based on the preferred embodiment of this technical solution, the dust collection assembly includes a support frame fixedly connected to the workbench, a fan body fixedly connected to one end of the support frame, a collection chamber fixedly connected to the other end of the support frame, a second waste collection frame detachably installed on the collection chamber, a universal adjusting pipe fixedly connected to the collection chamber at one end, a suction nozzle fixedly connected to the other end of the universal adjusting pipe, an exhaust pipe fixedly connected to the fan body, an intake pipe fixedly connected between the fan body and the collection chamber, a sealing ring fixedly connected to the intake pipe, and a filter plate slidably connected to the inner side of the sealing ring. The fan body is used to suck up dust through the universal adjusting pipes on both sides and the suction nozzle, so that the dust is collected on the second waste collection frame in the collection chamber.

[0009] In this preferred embodiment of the technical solution, both the intake pipe and the sealing ring have through grooves at corresponding positions on the filter plate, and the filter plate is slidably connected to the through grooves of the intake pipe and the sealing ring.

[0010] Based on the preferred embodiment of this technical solution, the cleaning component includes a fixed rod fixedly connected to the inner wall of the suction pipe, a second brush fixedly connected to the fixed rod on the same side as the filter plate, a semi-circular frame fixedly connected to one end of the filter plate, a third motor fixedly connected to the collection chamber, a rotating disk fixedly connected to the output end of the third motor, a light rod fixedly connected to the rotating disk, and a movable bracket rotatably connected at one end to the light rod. The other end of the movable bracket is rotatably connected to the semi-circular frame, and the third motor is used to drive the rotating disk to rotate.

[0011] Based on the preferred embodiment of this technical solution, four sets of fixing rods and two brushes are provided, and the four sets of fixing rods and two brushes are symmetrically distributed on the inner wall of the air intake pipe.

[0012] According to the preferred embodiment of this technical solution, the cutting assembly includes a fourth motor fixedly connected to the worktable and a cutting blade fixedly connected to the output end of the fourth motor.

The position of the nozzle can be flexibly adjusted by the universal adjustment pipe to adapt to the dust collection needs of different cutting positions. The filter plate can prevent powdery waste from entering the exhaust fan and causing damage, while the sealing ring enhances the sealing of the exhaust pipe and reduces dust leakage. The detachable second waste collection frame makes it easy to clean the collected dust regularly, reducing the difficulty of subsequent maintenance and making the dust collection component more convenient to use.

[0015] 3. The third motor drives the rotating disk to rotate, and the smooth rod on the rotating disk pulls the movable bracket, which in turn drives the semi-circular frame and filter plate to slide back and forth in the through groove.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-7This utility model provides an embodiment of a cutting device for manufacturing plastic products, including a workbench 1, a cutting component mounted on the workbench 1, a dust collection component mounted on the workbench 1, a cleaning component mounted on the dust collection component, a first waste collection frame 22 detachably mounted on the workbench 1, a discharge chute 21 located on the workbench 1 corresponding to the position of the first waste collection frame 22, a first cleaning frame 25 slidably connected to the workbench 1 at one end, a second cleaning frame 26 rotatably connected to the other end of the first cleaning frame 25, a first brush 27 fixedly connected to the first cleaning frame 25 and the second cleaning frame 26, and a brush fixedly connected to the outside of the first cleaning frame 25. The baffle 28 and the drive assembly set on the workbench 1 and the first cleaning frame 25 are used to drive the first cleaning frame 25 and the second cleaning frame 26 on both sides to move closer and further apart, and to rotate the second cleaning frame 26 on both sides relative to the first cleaning frame 25. After the plastic product is cut, the drive assembly can drive the first cleaning frame 25 and the second cleaning frame 26 on both sides to move closer together, and then drive the second cleaning frame 26 on both sides to rotate inward. With the help of the first brush 27, larger pieces of waste can be accurately guided into the first waste collection box 22 through the discharge chute 21. After the components are reset, the large pieces of waste can be cleaned up quickly, effectively preventing waste from occupying the operating space of the workbench 1 and interfering with the cutting. The streamlined workflow significantly improves overall operational efficiency, reduces equipment interference and maintenance costs caused by messy waste, and enhances operational efficiency. The exhaust fan 32 starts working, precisely absorbing powdery waste generated during cutting through the suction pipe 38, universal adjustment pipe 35, and suction nozzle 36. The position of the suction nozzle 36 can be flexibly adjusted via the universal adjustment pipe 35 to adapt to the dust collection needs of different cutting positions. The filter plate 310 prevents powdery waste from entering the exhaust fan 32 and causing damage, while the sealing ring 39 enhances the sealing of the suction pipe 38, reducing dust leakage. The detachable second waste collection frame 34 facilitates regular cleaning of the collected dust, reducing subsequent maintenance difficulty. To make the dust collection component more convenient to use, the third motor 44 drives the rotating disk 45 to rotate. The smooth rod 46 on the rotating disk 45 pulls the movable bracket 47, which in turn drives the semi-circular frame 43 and the filter plate 310 to slide back and forth in the through groove. During the sliding of the filter plate 310, the second brush 42 connected to the fixed rod 41 on the inner wall of the suction pipe 38 will wipe the surface of the filter plate 310, which can remove the dust attached to the filter plate 310 in time, and prevent the filter plate 310 from being blocked and affecting the suction efficiency. The entire cleaning process does not require manual operation, realizing the automatic cleaning of the filter plate 310, reducing the cost of manual maintenance, and ensuring the continuous and stable operation of the dust collection component.

[0021] Please see Figure 2-3A further solution based on this embodiment is as follows: The first drive unit includes a first motor fixedly connected to one side of the workbench and a bidirectional threaded rod rotatably connected to the workbench. The bidirectional threaded rod is fixedly connected to the output end of the first motor, and the first cleaning frame is threadedly connected to the bidirectional threaded rod. By adopting the structure of the first motor driving the bidirectional threaded rod, the movement direction and distance of the two sets of cleaning modules can be precisely controlled. The design of the bidirectional threaded rod allows the two sets of cleaning modules to simultaneously move closer or further away from each other, ensuring that the cleaning range covers the entire workbench surface. Compared with the traditional single-direction drive method, this improves cleaning efficiency and synchronization.

[0022] Please see Figure 2-3 A further solution based on this embodiment is as follows: The second drive unit includes a second motor fixedly connected to the first sweeping frame, the second sweeping frame is fixedly connected to the output end of the second motor, and the second motor is set inside the protective frame. The second motor directly drives the second sweeping frame to rotate, which can flexibly adjust the angle between the second sweeping frame and the first sweeping frame to adapt to the cleaning needs of waste materials of different shapes and positions. The setting of the protective frame can effectively protect the second motor from the influence of cutting dust and waste materials, extend the service life of the motor, and ensure the stable operation of the angle adjustment function.

[0023] Please see Figure 4-6 A further embodiment of this solution is as follows: the dust collection assembly includes a support frame fixedly connected to the workbench, a fan body fixedly connected to one end of the support frame, a collection chamber fixedly connected to the other end of the support frame, a second waste collection frame detachably installed on the collection chamber, a universal adjusting pipe fixedly connected to the collection chamber at one end, a suction nozzle fixedly connected to the other end of the universal adjusting pipe, an exhaust pipe fixedly connected to the fan body, an intake pipe fixedly connected between the fan body and the collection chamber, a sealing ring fixedly connected to the intake pipe, and a filter plate slidably connected to the inner side of the sealing ring. The exhaust fan body is used to suck up dust through the universal adjustable pipes on both sides and the suction nozzle, collecting it into the second waste collection frame in the collection chamber. The suction provided by the exhaust fan body can suck up the dust and fine waste generated during the cutting process through the suction nozzle, transport it to the collection chamber through the universal adjustable pipe and the air intake pipe, and fall into the second waste collection frame, thus achieving effective control of air pollutants. The universal adjustable pipe can flexibly adjust the position of the suction nozzle to ensure that the dust suction range covers the cutting area. The filter plate can prevent dust from entering the exhaust fan body and causing damage, and the sealing ring enhances the sealing of the air intake pipe and improves dust suction efficiency.

[0024] Please see Figure 6A further solution based on this embodiment is as follows: both the suction pipe and the sealing ring have through grooves at corresponding positions on the filter plate. The filter plate is slidably connected to the through grooves of the suction pipe and the sealing ring. By opening through grooves on the suction pipe and the sealing ring and slidably connecting the filter plate therein, the filter plate can be easily disassembled and replaced. When a lot of dust accumulates on the filter plate and affects the ventilation effect, it can be quickly pulled out for cleaning or replacement. The through groove structure also ensures the stability and sealing of the filter plate after installation, avoiding a decrease in dust collection efficiency due to the filter plate loosening.

[0025] Please see Figure 6 A further solution based on this embodiment is as follows: The cleaning component includes a fixed rod fixedly connected to the inner wall of the suction pipe, a second brush fixedly connected to the fixed rod on the same side as the filter plate, a semi-circular frame fixedly connected to one end of the filter plate, a third motor fixedly connected to the collection chamber, a rotating disk fixedly connected to the output end of the third motor, a smooth rod fixedly connected to the rotating disk, and a movable bracket rotatably connected to the smooth rod at one end. The other end of the movable bracket is rotatably connected to the semi-circular frame. The third motor is used to drive the rotating disk to rotate. Through the rotation of the rotating disk driven by the third motor, and the transmission through the smooth rod and the movable bracket, the filter plate can slide back and forth in the through groove. With the help of the second brush on the fixed rod, the surface of the filter plate can be automatically cleaned, and the attached dust can be shaken off into the collection chamber, avoiding the filter plate from clogging and affecting the dust collection effect. Frequent manual cleaning is not required, reducing maintenance costs and ensuring the continuous and stable operation of the dust collection component.

[0026] Please see Figure 6 A further solution based on this embodiment is as follows: four sets of fixing rods and two brushes are provided. The four sets of fixing rods and two brushes are symmetrically distributed on the inner wall of the air intake pipe. By setting four sets of symmetrically distributed fixing rods and two brushes, the filter plate can be cleaned from multiple directions, ensuring that all areas of the filter plate surface can be thoroughly cleaned. Compared with a single set of brushes, the cleaning effect and efficiency are improved. The symmetrical distribution structure also makes the filter plate more evenly stressed during reciprocating motion, reducing component wear.

[0027] Please see Figure 7 A further solution based on this embodiment is as follows: the cutting assembly includes a fourth motor fixedly connected to the worktable and a cutting blade fixedly connected to the output end of the fourth motor. The cutting blade is directly driven to rotate by the fourth motor, which can provide stable power output for cutting plastic products, ensuring a smooth and efficient cutting process. The structure is simple and compact, easy to install and maintain. At the same time, the motor speed can be adjusted to adapt to plastic products of different materials and thicknesses according to different cutting needs, thereby improving the versatility of the device.

[0028] The dual-cylinder drive structure replaces the first motor 23 + bidirectional threaded rod 24, resulting in faster cylinder drive response, shorter movement time of the first sweeping frame 25, and improved waste cleaning efficiency; the servo motor is smaller and has higher control precision, eliminating the need for a complex threaded rod transmission structure and reducing mechanical wear.

[0029] A rolling guide rail is used instead of the groove opened on the worktable 1 for the first cleaning frame 25. Ball bearings are embedded in the guide rail, and the bottom of the first cleaning frame 25 slides in cooperation with the guide rail. The rolling guide rail reduces the frictional resistance between the first cleaning frame 25 and the worktable 1 through the ball bearings, making the first cleaning frame 25 move more smoothly, reducing the load on the first motor 23 and extending the service life of the motor. At the same time, the guide rail structure has higher positioning accuracy, avoiding the wear and displacement problem that occurs after long-term use of the original straight groove, ensuring that the first cleaning frame 25 always moves along the preset path and improving the accuracy of waste collection.

[0030] Working principle: First, the position of the suction nozzle 36 in the dust collection assembly is adjusted using the universal adjustment tube 35 to align it with the area where powdery waste may be generated during subsequent cutting operations. Simultaneously, the detachable first waste collection frame 22 is installed below the corresponding discharge chute 21 on the workbench 1, completing the pre-operation preparation. Then, the fourth motor 51 in the cutting assembly is started, driving the cutting blade 52 at the output end to rotate at high speed. The operator uses the rotating cutting blade 52 to cut the plastic product. During the cutting process, the exhaust fan body 32 of the dust collection assembly is simultaneously activated, drawing out the dust through the suction nozzle. Negative pressure is generated in the air duct 38, and the powdery waste generated during cutting enters the collection chamber 33 through the suction nozzle 36 and the universal adjustment pipe 35, and is collected in the second waste collection frame 34. The filter plate 310 on the suction duct 38 can prevent the powdery waste from entering the exhaust fan body 32 and causing damage, while the sealing ring 39 ensures the airtightness of the suction duct 38 and avoids dust leakage. After the cutting operation is completed, the drive assembly is started, and the first motor 23 drives the bidirectional threaded rod 24 to rotate, so that the two sets of first cleaning frames 25 threaded on the bidirectional threaded rod 24 move closer to each other along the slide groove of the worktable 1. When the first cleaning frame 25 moves to the appropriate position, the second cleaning frame 25 moves closer to the first cleaning frame 25. The second motor 29 drives the second sweeping frame 26 to rotate inward. The first brushes 27 on the first sweeping frame 25 and the second sweeping frame 26 gather larger pieces of waste on the workbench 1 towards the discharge chute 21. Finally, the waste falls into the first waste collection box 22 through the discharge chute 21. Then, the first sweeping frame 25 and the second sweeping frame 26 on both sides reset, waiting for the next cleaning. The baffles 28 on both sides limit the rotation direction of the second sweeping frame 26, so that it can only rotate inward. During the continuous operation of the device, the cleaning components will be activated periodically. The third motor 44 drives the rotating disk 45 to rotate. The polished rod 46 on the rotating disk 45 passes through... The movable bracket 47 pulls the semi-circular frame 43, causing the filter plate 310 connected to the semi-circular frame 43 to slide back and forth in the through groove of the suction pipe 38 and the sealing ring 39. The four sets of symmetrically distributed fixed rods 41 and the second brush 42 on the inner wall of the suction pipe 38 will wipe the surface of the filter plate 310 when it slides, and remove the dust attached to the filter plate 310 in time to avoid clogging of the filter plate 310 and affecting the exhaust efficiency. When the waste in the first waste collection frame 22 and the second waste collection frame 34 reaches a certain amount, they can be removed from the workbench 1 and the collection chamber 33 respectively for cleaning. After cleaning, they can be reinstalled for continued use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
