Description

Technical Field

[0001] This invention relates to the field of mechanical drilling technology, and more specifically to a drilling device for plastic products. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with malleability, and drilling is necessary when processing plastic products.

[0003] During the processing of plastic pipes, it is sometimes necessary to drill holes in them. During the drilling process, strip-shaped debris is generated and blown out by the drill bit, which can easily cause injury to nearby workers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is as follows: A punching device for plastic products according to this invention includes: a machine base, a drive box fixedly connected to the bottom of the machine base, and a frame fixedly connected to the top of the machine base;

[0005] The punching equipment for this plastic product also includes:

[0006] A collection mechanism, wherein the outer wall of the collection mechanism is fixedly connected to the inner wall of the machine base;

[0007] The collection mechanism includes a water collection tank, the outer wall of which is fixedly connected to the inner wall of the machine, and cleaning components are evenly arranged on the inner wall of the water collection tank, with the outer wall of the cleaning components fixedly connected to the inner wall of the water collection tank.

[0008] The punching mechanism, wherein the outer surface of the punching mechanism is fixedly connected to the outer wall of the frame;

[0009] The drilling mechanism includes a cylinder, a drive seat is fixedly connected to the bottom of the cylinder, protective components are evenly arranged on the bottom of the drive seat, grinding components are evenly arranged on the bottom of the drive seat, sliders are symmetrically arranged at both ends of the drive seat, and a fixing component is fixedly connected to the bottom of the slider.

[0010] Furthermore, the top of the protective assembly is rotatably connected to the bottom of the drive seat, the top of the grinding assembly is rotatably connected to the bottom of the drive seat, and the outer wall of the slider is slidably connected to the inner wall of the drive seat.

[0011] Furthermore, the collection mechanism also includes a baffle, the bottom of which is fixedly connected to the top of the water collection tank. A collection box is fixedly connected to the outer wall of the water collection tank, and a filter cloth is fixedly connected to the inner wall of the water collection tank. Cards are evenly arranged on the top of the water collection tank, and the bottom of the cards is fixedly connected to the top of the machine. This reduces the use of external water sources. The cleaning component cleans the plastic debris on the filter cloth into the collection box for recycling, allowing the debris and water to be recycled and reused separately. This enhances the cleanliness of the machine surface, improves the recycling rate of plastic debris, and reduces the cleaning difficulty for workers.

[0012] Furthermore, the drilling mechanism also includes a water pipe, the outer wall of which is fixedly connected to the outer surface of the drive seat, and the outer wall of the drive seat is slidably connected to the outer wall of the frame. Spray nozzles are evenly distributed at the bottom of the water pipe, and the top of each spray nozzle is fixedly connected to the bottom of the water pipe. After drilling the plastic pipe, the grinding component performs small-scale grinding on the inner wall of the hole to keep the hole diameter unchanged while ensuring a smooth inner wall. The fixing component facilitates the flow of water from the plastic pipe being blocked by a baffle. After cleaning the debris from the pipe, the worker removes the plastic pipe and places a new plastic pipe to continue drilling. After drilling the plastic pipe, the inner wall of the hole is ground to make it smooth, cleaning up burrs and rough edges that appear during the drilling process, preventing debris from flying out and causing injury to workers, and improving product quality.

[0013] Furthermore, the cleaning assembly includes a first motor, the outer wall of which is fixedly connected to the inner wall of the water collection tank. A bent rod is fixedly connected to the outer wall of the first motor, and a fixed plate is fixedly connected to the outer wall of the bent rod. Support rods are symmetrically arranged at the bottom of the fixed plate, the top of the support rods is fixedly connected to the outer surface of the fixed plate, and a scraper is fixedly connected to the bottom of the support rods. This reduces the workload of the workers cleaning the machine surface, filters the cooling water, and allows both plastic debris and water to be recycled and reused, saving resources and reducing production costs.

[0014] Furthermore, the fixing component includes a first telescopic column, the top of which is fixedly connected to the bottom of the slider. An arc-shaped shell is fixedly connected to the bottom of the first telescopic column. An electric actuator is fixedly connected to the top of the inner wall of the arc-shaped shell, and a pad is fixedly connected to the bottom of the electric actuator. Clamping plates are symmetrically arranged on the inner wall of the arc-shaped shell. The outer wall of the clamping plates is rotatably connected to the inner wall of the arc-shaped shell. The top of the clamping plates is engaged with the inner wall of the pad to enhance the stability of drilling. After drilling, one side of the plastic tube is raised to facilitate the cleaning and discharge of debris inside the plastic tube, reducing debris residue inside the plastic tube after drilling and keeping the product clean.

[0015] Furthermore, the protective assembly includes a protective shell, two of which are symmetrically arranged. The top of the protective shell is rotatably connected to the bottom of the drive seat. A second telescopic column is fixedly connected to the outer wall of the protective shell. A telescopic rod is rotatably connected to one end of the second telescopic column near the protective shell. A square hole is opened at the bottom of the protective shell. A scraper is rotatably connected to the bottom of the telescopic rod to prevent debris generated during drilling from flying outwards and easily causing injury to workers. After drilling is completed, the second telescopic column extends, driving the scraper to move back and forth along the top of the plastic tube, so that the scraper can scrape off the excess residue on the surface of the plastic tube after drilling, keeping the surface of the plastic tube smooth.

[0016] Furthermore, the grinding assembly includes a rotating shaft, the top of which is rotatably connected to the bottom of the drive seat. A drill bit is fixedly connected to the bottom of the rotating shaft. A limit block is provided on the outer surface of the rotating shaft. The top of the limit block is rotatably connected to the bottom of the drive seat. Limit grooves are evenly formed on the bottom of the limit block. A connecting rod is slidably connected to the top of the inner wall of the limit groove. A scraper is fixedly connected to the bottom of the connecting rod. The bottom of the scraper is slidably connected to the top of the drill bit. A second spring is fixedly connected to the top of the inner wall of the drill bit. A push plate is fixedly connected to the bottom of the second spring. This ensures that the drill bit can trim and clean the inner wall of the hole without enlarging the hole diameter, making the inner wall of the hole smooth and improving product quality.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. During the drilling process of plastic pipes, strip-shaped debris is generated and flies out, which can easily cause injury to nearby workers. This invention sets up a drilling mechanism to grind the inner wall of the hole after drilling the plastic pipe, making the hole wall smooth. At the same time, it cleans the burrs and rough edges that appear on the surface of the plastic pipe during the drilling process. The protective component shields the drilling position to prevent debris from flying out and causing injury to workers, thereby improving product quality.

[0019] 2. After drilling, debris and discs fall inside the plastic tube, resulting in a large amount of debris inside. This invention addresses this by setting up cleaning and fixing components to raise one side of the plastic tube after drilling, facilitating the removal of debris from inside the tube. This reduces debris residue inside the plastic tube after drilling, keeps the product clean, reduces the workload of workers cleaning the machine surface, and filters the cooling water, allowing both plastic debris and water to be recycled and reused, saving resources and reducing production costs.

[0020] 3. Since drilling produces a lot of burrs, which is not conducive to handling by workers, this invention sets up a protective component to prevent the debris generated during drilling from flying outwards and easily causing injury to workers. The scraper bar scrapes off the excess residue and burrs on the surface of the plastic tube after drilling, keeping the surface of the plastic tube smooth and facilitating manual transportation and handling.

[0021] 4. When drilling large-diameter holes, drilling with a drill bit will cause strip-shaped debris to appear on the plastic tube, and drill marks and burrs will appear on the inner wall of the hole. This invention, by setting up a grinding component, can trim and clean the inner wall of the hole without enlarging the hole diameter, making the inner wall of the hole smooth, improving product quality, reducing burrs and rough edges on the surface of the plastic tube, and making it easier for workers to handle.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] Example 1, using Figures 1-5 The following describes a punching device for a plastic product according to one embodiment of the present invention.

[0034] like Figures 1-5 As shown, the punching device for plastic products of the present invention includes: a machine base 1, a drive box 2 fixedly connected to the bottom of the machine base 1, and a frame 4 fixedly connected to the top of the machine base 1.

[0035] The punching equipment for this plastic product also includes:

[0036] The outer wall of the collection mechanism 3 is fixedly connected to the inner wall of the machine base 1;

[0037] The collection mechanism 3 includes a water collection tank 301, the outer wall of which is fixedly connected to the inner wall of the machine base 1, and cleaning components 306 are evenly arranged on the inner wall of the water collection tank 301, with the outer wall of the cleaning components 306 fixedly connected to the inner wall of the water collection tank 301.

[0038] The outer surface of the punching mechanism 5 is fixedly connected to the outer wall of the frame 4;

[0039] The drilling mechanism 5 includes a cylinder 501, a drive seat 502 fixedly connected to the bottom of the cylinder 501, protective components 505 evenly arranged on the bottom of the drive seat 502, grinding components 506 evenly arranged on the bottom of the drive seat 502, sliders 507 symmetrically arranged at both ends of the drive seat 502, and a fixing component 504 fixedly connected to the bottom of the sliders 507.

[0040] The top of the protective component 505 is rotatably connected to the bottom of the drive seat 502, the top of the grinding component 506 is rotatably connected to the bottom of the drive seat 502, and the outer wall of the slider 507 is slidably connected to the inner wall of the drive seat 502.

[0041] During operation, the worker places the plastic tube on top of the collection mechanism 3, then opens the drive box 2, causing the cylinder 501 to push the drive seat 502 downward along the frame 4. The fixing component 504 presses and fixes the plastic tube, and then the grinding component 506 drills holes. At the same time, an external water source sprays water to cool the plastic tube. The protective component 505 shields the plastic debris generated during drilling, causing it to be concentrated inside the water collection tank 301. The cleaning component 306 cleans the debris inside the water collection tank 301. After drilling, the drive seat 502 tilts the plastic tube, and the water source continues to flow, cleaning out the plastic discs that have fallen inside the plastic tube. Finally, they are collected in the collection tank 303. After drilling is completed, the plastic tube is removed.

[0042] The collection mechanism 3 also includes a baffle 302, the bottom of which is fixedly connected to the top of the water collection tank 301. A collection box 303 is fixedly connected to the outer wall of the water collection tank 301, and a filter cloth 304 is fixedly connected to the inner wall of the water collection tank 301. Card plates 305 are evenly arranged on the top of the water collection tank 301, and the bottom of the card plates 305 is fixedly connected to the top of the machine base 1.

[0043] Before drilling, the worker places the plastic tube on the clamping plate 305, securing it at the angle of the clamping plate 305. During drilling, an external water source cools the plastic tube. The cooled water flows into the collection tank 303, is filtered through the filter cloth 304, and then flows back to the water pipe 503 to mix with the external water source for further cooling, reducing the use of the external water source. The cleaning component 306 cleans the plastic debris on the filter cloth 304 into the collection tank 303 for recycling, allowing the debris and water to be recycled and reused separately. This enhances the cleanliness of the machine surface 1, improves the recycling rate of plastic debris, and reduces the cleaning difficulty for the workers.

[0044] The drilling mechanism 5 also includes a water pipe 503. The outer wall of the water pipe 503 is fixedly connected to the outer surface of the drive seat 502. The outer wall of the drive seat 502 is slidably connected to the outer wall of the frame 4. Spray nozzles 508 are evenly arranged at the bottom of the water pipe 503. The top of the spray nozzles 508 is fixedly connected to the bottom of the water pipe 503.

[0045] During operation, cylinder 501 drives drive seat 502 downward, bringing its two end fixing components 504 into contact with the plastic tube and pressing them firmly, thus securing the plastic tube within the fixing components 504. Then, cylinder 501 drives drive seat 502 further downward, causing grinding component 506 to drill a hole in the plastic tube. Water pipe 503 is connected to both the water source and return water, and water is sprayed onto the drilled area through nozzle 508 to cool it down. After drilling the plastic tube, grinding component 506 performs small-scale grinding on the inner wall of the hole, making the hole diameter remain the same but the hole wall smoother. During the drilling process, protective component 505 shields the drilled area. The nozzle 508 acts as a shield to prevent debris from flying out and injuring workers. It also scrapes the surface of the plastic tube to remove burrs generated during the drilling process. After drilling is completed, the drive seat 502 drives the fixing component 504 near the end of the baffle 302 to lift the plastic tube. The fixing components 504 on both sides are at different heights. The nozzle 508 continuously sprays water to flush the debris inside the plastic tube outward. The end of the plastic tube near the baffle 302 is lower, so that the water inside the plastic tube is blocked by the baffle 302 when it flows out. After the debris inside the tube is cleaned, the workers remove the plastic tube and place a new plastic tube to continue drilling.

[0046] Example 2, using Figures 1-9 The following describes a punching device for a plastic product according to one embodiment of the present invention.

[0047] like Figures 1-9 As shown, the punching device for plastic products of the present invention, based on Embodiment 1, includes a cleaning component 306 comprising a first motor 3061, the outer wall of the first motor 3061 being fixedly connected to the inner wall of the water collection tank 301, a bent rod 3062 being fixedly connected to the outer wall of the first motor 3061, a fixed plate 3063 being fixedly connected to the outer wall of the bent rod 3062, support rods 3064 being symmetrically arranged at the bottom of the fixed plate 3063, the top of the support rods 3064 being fixedly connected to the outer surface of the fixed plate 3063, and a scraper 3065 being fixedly connected to the bottom of the support rods 3064.

[0048] After the cooling water washes the debris and plastic discs generated during the perforation of the plastic pipe onto the filter cloth 304, the first motor 3061 is activated, driving the bent rod 3062 to rotate. This allows the fixing disc 3063 on the bent rod 3062 to contact the filter cloth 304 and press it downwards. The filter cloth 304 is then tilted within the water collection tank 301. The five sets of first motors 3061 are activated sequentially, each driving the fixing disc 3063 to rotate and contact the filter cloth 304 in turn. With the help of 63, the surface of the filter cloth 304 vibrates, causing large pieces of plastic debris to move along the filter cloth 304 into the collection box 303. Smaller debris adheres to the filter cloth 304 and is then scraped by the scraper 3065. The five sets of scrapers 3065 pass through in sequence, causing the smaller debris to accumulate and be cleaned into the collection box 303. This reduces the workload of the staff cleaning the surface of the machine 1, filters the cooling water, and allows both plastic debris and water to be recycled and reused, saving resources and reducing production costs.

[0049] The fixing component 504 includes a first telescopic column 5041, the top of which is fixedly connected to the bottom of the slider 507. An arc-shaped shell 5042 is fixedly connected to the bottom of the first telescopic column 5041. An electric push rod 5043 is fixedly connected to the top of the inner wall of the arc-shaped shell 5042. A pad 5044 is fixedly connected to the bottom of the electric push rod 5043. Clamping plates 5045 are symmetrically arranged on the inner wall of the arc-shaped shell 5042. The outer wall of the clamping plate 5045 is rotatably connected to the inner wall of the arc-shaped shell 5042. The top of the clamping plate 5045 is engaged with the inner wall of the pad 5044.

[0050] Before drilling, the drive seat 502 gradually approaches the plastic tube. Driven by the first telescopic column 5041, the arc-shaped shell 5042 and the pad 5044 first contact the surface of the plastic tube. The distance between the clamping plates 5045 is less than the diameter of the plastic tube, so that when approaching the plastic tube downwards, downward pressure is maintained. The electric actuator 5043 extends, causing the pad 5044 to press against the clamping plates 5045, keeping the clamping plates 5045 in an open state. After drilling is completed, the first telescopic column 5041 on the side near the baffle 302 remains stationary, while the first telescopic column 5041 on the other side retracts. As the first telescopic column 5041 drives the arc-shaped shell 5042 to rise, the electric actuator 5043 drives the pad 5044 to move upward, causing the clamping plate 5045 to close and clamp the plastic tube. The contact points between the arc-shaped shell 5042 and the plastic tube, as well as the clamping plate 5045, are made of rubber. During drilling, the arc-shaped shell 5042 keeps the plastic tube stationary, enhancing the stability of the drilling. After drilling, one side of the plastic tube is raised to facilitate the cleaning and discharge of debris inside the plastic tube, reducing debris residue inside the plastic tube after drilling and keeping the product clean.

[0051] The protective assembly 505 includes a protective shell 5051, two of which are symmetrically arranged. The top of the protective shell 5051 is rotatably connected to the bottom of the drive seat 502. A second telescopic column 5052 is fixedly connected to the outer wall of the protective shell 5051. A telescopic rod 5054 is rotatably connected to one end of the second telescopic column 5052 near the protective shell 5051. A square hole 5053 is opened at the bottom of the protective shell 5051. A scraper 5055 is rotatably connected to the bottom of the telescopic rod 5054.

[0052] During drilling, the drive seat 502 drives the grinding mechanism to approach the plastic tube. During this approach, the protective shell 5051 remains extended. During drilling, the protective shell 5051 is engaged with the outer wall of the clamping plate 305. The telescopic rod 5054 adjusts the position of the scraper 5055 so that the scraper 5055 contacts the top of the plastic tube. The bottom of the scraper 5055 is a thin metal sheet, which is easy to deform and fits against the outer wall of the plastic tube, preventing the debris generated during drilling from flying outward and potentially injuring the workers. After drilling is completed, the second telescopic column 5052 extends, driving the scraper 5055 to move back and forth along the top of the plastic tube, scraping off any excess residue on the surface of the plastic tube after drilling, keeping the surface of the plastic tube smooth.

[0053] The grinding assembly 506 includes a rotating shaft 5061, the top of which is rotatably connected to the bottom of the drive seat 502. A drill bit 5062 is fixedly connected to the bottom of the rotating shaft 5061. A limit block 5063 is provided on the outer surface of the rotating shaft 5061. The top of the limit block 5063 is rotatably connected to the bottom of the drive seat 502. Limit grooves 5064 are evenly opened on the bottom of the limit block 5063. A connecting rod 5065 is slidably connected to the top of the inner wall of the limit groove 5064. A scraper 5066 is fixedly connected to the bottom of the connecting rod 5065. The bottom of the scraper 5066 is slidably connected to the top of the drill bit 5062. A second spring 5067 is fixedly connected to the top of the inner wall of the drill bit 5062. A push plate 5068 is fixedly connected to the bottom of the second spring 5067.

[0054] Before drilling, the connecting rod 5065 slides within the limiting groove 5064 of the limiting block 5063 by rotating the limiting block 5063, so that the unfolded length of the six sets of scraper blades 5066 is the same as the diameter of the drill bit 5062. The surface of the scraper blades 5066 is covered with a layer of sandpaper. During drilling, the drive seat 502 drives the rotating shaft 5061 to rotate, so that the drill bit 5062 drills into the plastic tube. After the drill bit 5062 drills into the plastic tube, it continues to rotate. At this time, the sandpaper on the surface of the scraper blades 5066 contacts the inner wall of the hole, polishing and cleaning the protruding debris and residue on the hole wall. During drilling, the push plate 5068 gradually approaches the plastic tube, and after drilling is completed, it pushes the cut plastic piece down into the inside of the plastic tube for cleaning and recycling. This allows for the trimming and cleaning of the inner wall of the hole without enlarging the hole diameter, making the inner wall of the hole smooth and improving product quality.

[0055] The specific workflow is as follows:

[0056] During operation, the worker places the plastic tube on the clamping plate 305, then opens the drive box 2. The cylinder 501 drives the drive seat 502 downwards, bringing its two end fixing components 504 into contact with the plastic tube and pressing them firmly, thus securing the plastic tube within the fixing components 504. The cylinder 501 then drives the drive seat 502 further downwards, causing the grinding component 506 to drill a hole in the plastic tube. A water pipe 503 is connected to both the external water source and the return water supply. Water is sprayed onto the drilled area through the nozzle 508 to cool it. After drilling the hole, the grinding component 506 performs small-scale grinding on the inner wall of the hole, ensuring the hole diameter remains unchanged while maintaining a smooth inner wall. After drilling is complete, the drive seat... 502 drives the fixing component 504 near the baffle 302 to lift the plastic tube. The fixing components 504 on both sides are at different heights. The nozzle 508 continuously sprays water to flush the debris inside the plastic tube outward. The end of the plastic tube near the baffle 302 is lower, so that the water inside the plastic tube is blocked by the baffle 302 when it flows out. The cooled water flows into the collection box 303, is filtered by the filter cloth 304, and then flows back to the water pipe 503 to mix with the external water source for continued cooling and use, reducing the use of the external water source. The cleaning component 306 cleans the plastic debris on the filter cloth 304 into the collection box 303 for recycling. After the perforation is completed, the plastic tube is removed.
