Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic cutting technology, specifically a plastic product processing and cutting device. Background Technology
[0002] Plastic rods, as a common profile material, are widely used in the manufacture of parts, models, fixtures, and various daily necessities. During the production process, it is often necessary to cut long extruded plastic rods into segments of specific lengths for subsequent processing or direct use.
[0003] An existing patent (authorization announcement number: CN222819061U) discloses a cutting device for processing plastic products. The key technical points of the solution are: when using the equipment, the operator places the plastic product to be processed at the bottom of the turntable, and starts the pneumatic telescopic rod to move the clamping plate down to clamp and stabilize the plastic product. Then, the servo motor is started to rotate, driving the turntable and thus rotating the plastic product. The operator cuts the plastic product by moving the moving seat and operating the telescopic rod one and the cutting blade. In addition, after the rotation stops, the operator drills holes in the plastic product by moving the moving seat and operating the telescopic rod two and the drilling head. When it is necessary to fix the moving seat, the clamping bolt can be rotated to penetrate into the middle of the moving seat and the clamping part is clamped in the fixing groove and the top of the gantry, which facilitates fixing the position of the moving seat and facilitates auxiliary operation.
[0004] However, the above-mentioned technical solutions still have certain drawbacks. During the cutting process, the plastic rods soften after being heated and tend to adhere to the surface of the cutting disc, causing the cutting edge to become dull and clogged. This not only makes the cut surface rough, produces burrs, or even stringing, affecting product quality, but also requires operators to frequently stop the machine to clean or replace the cutting disc, severely reducing production efficiency and increasing consumable costs. Therefore, a plastic product processing and cutting device is proposed. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0019] In one embodiment, such as Figures 1-5As shown, a plastic product processing and cutting device includes a frame 1, a controller 2 is fixedly installed on the top of the frame 1, a clamping component 3 for clamping plastic rods is also provided on the top of the frame 1, and a cutting component 4 for cutting plastic rods is provided directly above the clamping component 3. A cleaning component 5 for cleaning the cut rods is installed on the side of the cutting component 4. In this embodiment, the clamping component 3 provides clamping force to prevent the rod from vibrating or rotating during the cutting process. At the same time, the cutting component 4 is activated to perform rotary cutting on the plastic rod. The cleaning component 5 immediately sprays water to clean the workpiece after cutting to prevent flying chips and cool the cutting blade.
[0020] In one embodiment, such as Figure 2 As shown, the clamping assembly 3 includes a first electric push rod 31 fixedly mounted on the frame 1. The output end of the first electric push rod 31 is provided with a movable push block. The top of the frame 1 is also equipped with a first cylinder 33, a push block driven by the first cylinder 33 for pushing plastic rods, a sensor 32 for detecting whether the rod is in position, a second cylinder 34 for tightening the rod, and a clamping plate 35 corresponding to the second cylinder 34. The output end of the second cylinder 34 is provided with a movable push block, which is made of rubber. When the operator places the rod, the first electric push rod 31 is activated, and its output end pushes the movable push block... The block moves forward, pushing the rod forward. When its front end reaches the preset cutting length position, it triggers the photoelectric sensor 32. The sensor 32 sends a signal to the controller 2, informing that the rod has been delivered to the designated position. After receiving the signal from the sensor 32, the controller 2 immediately sends a command to the second cylinder 34. The output end of the second cylinder 34 extends rapidly, driving the movable push block at its front end to move forward. The movable push block works in conjunction with the fixed clamping plate 35 on the opposite side to firmly clamp the plastic rod from both sides, preventing it from moving during the cutting process. The rubber movable push block prevents the rod from slipping and prevents metal indentations from being left on the rod.
[0021] In one embodiment, such as Figure 3 and Figure 4As shown, the cutting assembly 4 includes a mounting bracket 41 fixedly mounted on the top of the frame 1. A second electric push rod 42 is rotatably mounted on the side of the mounting bracket 41. A mounting handle 43 is rotatably mounted on the output end of the second electric push rod 42, and a moving handle 44 is fixedly provided at the bottom of the mounting handle 43. A protective shell 46 is provided at the bottom of the moving handle 44, and a drive motor 45 is fixedly mounted on the side of the protective shell 46. The drive motor 45 drives the cutting disc 47. The protective shell 46 is rotatably mounted on the top of the mounting bracket 41. A mounting shell 48 is also fixedly mounted on the bottom side of the mounting bracket 41. The top of the mounting shell 48 has a groove to facilitate the entry of the cutting disc 47, and a grinder 49 for grinding the cutting disc 47 is also provided inside the mounting shell 48. The grinder 49 is V-shaped, and the middle groove is made of abrasive material. The cutting disc 47 is started by the drive motor 45. The high-speed rotation of the cutting blade 47 causes the second electric push rod 42 to extend. Since its cylinder and push rod end are rotatably mounted, it pushes the entire linkage mechanism (mounting handle 43, moving handle 44, protective shell 46, motor and cutting blade 47) to swing downwards around the rotational connection point between the protective shell 46 and the mounting bracket 41. The rotating cutting blade 47 moves downwards, contacts and cuts the clamped and fixed plastic rod. After cutting, when the cutting blade 47 reaches its lowest point, it continues to descend a short distance through the groove at the top of the mounting shell 48 and enters the interior of the mounting shell 48. When the two sides of the cutting blade 47 contact this V-shaped abrasive groove, the high-speed rotating cutting blade 47 is automatically polished. Regular automatic polishing can effectively remove the adhered plastic, prevent the clogging phenomenon from aggravating the damage to the cutting blade 47 substrate and diamond, thereby extending its service life and reducing the frequency and cost of replacing the saw blade.
[0022] In one embodiment, such as Figure 5As shown, the cleaning assembly 5 includes a mounting column 51 fixedly installed on the top of the frame 1. A water tank is integrated within the mounting column 51, and the water tank is connected to a water spray pipe 52. A flexible hose 53 is fixedly installed on the side of the water spray pipe 52. A water pump is installed inside the water tank. A collection box 54 is slidably installed on the top of the mounting housing 48. The top of the collection box 54 has multiple drainage holes, and a baffle 55 is provided on the periphery of the top of the collection box 54. The collection box 54 is detachably connected to the mounting housing 48. When the water pump is activated, water from the water tank is pumped into the water spray pipe 52 through the flexible hose 53. The water spray pipe 52 sprays water in a directional direction onto the cut surface of the plastic rod, reducing the heat generated during cutting, preventing the plastic cut surface from melting due to overheating, and washing away plastic debris and dust adhering to the cut surface. Simultaneously, the splashed debris is flushed away from the work area and cleans the cutting disc 47. The collection box 54, due to its sliding installation and location on top of the mounting shell 48 directly below the cutting assembly 4, is situated below the cutting and rinsing area, naturally catching the wastewater and plastic debris washed down. The waste liquid mixed with debris falls into the collection box 54. Multiple holes on the top of the box act as a filter, allowing the liquid to leak down while intercepting larger plastic debris within the collection box 54. Baffles 55 on the periphery of the collection box 54 prevent wastewater from splashing outwards under impact, ensuring that all waste liquid and debris are effectively confined within the collection box 54, maintaining a clean working environment. After processing for a period of time, the operator can pull out the entire collection box 54, empty and clean the accumulated plastic debris for recycling.
[0023] In one embodiment, such as Figure 1 As shown, the water pump of the cleaning component 5 is electrically connected to the controller 2, and the controller 2 is configured to: delay starting the water pump after receiving a signal that the cutting blade 47 has started to move downwards; and delay shutting off the water pump after receiving a signal that the cutting blade 47 has risen and reset; the water pump only operates during the critical cutting period, rather than continuously spraying water throughout the entire processing cycle. This avoids unnecessary waste of water resources during loading and unloading, and when the equipment is running idle. The delayed start ensures that the water flow is precisely applied to the cutting surface and high-temperature area, resulting in the best rinsing effect. The delayed shutdown ensures that the cut surface and the cutting blade 47 are sufficiently cooled, preventing the plastic from melting and adhering due to residual heat.
[0024] The above embodiment discloses a plastic product processing and cutting device, wherein a long rod is manually placed in the machine, a first electric push rod 31 pushes the rod, a sensor 32 detects that the rod is in place, a second cylinder 34 drives a rubber block to clamp it, at which time the cutting blade 47 swings downward to complete the cutting, the cutting blade 47 penetrates into the mounting shell 48 V-shaped grinding stone for automatic grinding, the controller 2 controls the water pump to start, spray water to clean the plastic cross-section to prevent heat melting, and at the same time clean the cutting blade 47, wastewater and debris flow into the collection box 54, and are prevented from splashing by the baffle 55.
