Description

Technical Field

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

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics, including products manufactured using all processes such as injection molding and thermoforming. Specifically, plastics are materials made primarily of natural or synthetic resins with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and maintain their shape at room temperature. During the production of cylindrical plastic products, burrs are inevitable on the surface, requiring polishing to smooth the outer surface.

[0003] Chinese patent application CN202120004052.1 discloses a grinding device for plastic products, including a base plate. A guide groove is formed on the upper surface of the base plate, and a first sliding plate and a second sliding plate are movably connected to the base plate via the guide groove. A first telescopic rod is provided on the upper surface of the first sliding plate. This utility model, by providing a replaceable grinding disc, can adapt to different types of plastic products, improving the utilization rate of a single device and reducing equipment investment costs. By providing clamping rings with adjustable spacing, it can fix plastic products of different sizes, improving the versatility of the grinding process. By mounting the clamping disc on a motor, the object being ground can rotate to adjust the grinding angle. Combined with a lifting mechanism, it can achieve grinding of complex irregular surfaces. Through optimized structural design, it reduces equipment setup costs, improves grinding efficiency, and is suitable for various complex grinding surfaces.

[0004] However, when the grinding device in this patent grinds the burrs on the surface of plastic products, the friction generates a high temperature, and a lot of plastic waste is produced during the grinding process. If it is not cleaned, the high temperature will melt the waste during the grinding process and stick to the surface of the plastic products, thereby further affecting the grinding effect.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 13 As shown, the present invention provides a grinding device for processing plastic products, comprising: a machine base 1; a mounting cover 2 fixedly installed on the machine base 1; a grinding mechanism for grinding plastic products; and a cooling mechanism for cooling down the plastic products during grinding.

[0023] The polishing mechanism includes: a power source 3 fixedly mounted on the mounting cover 2; a mounting plate 4 fixedly mounted on the movable end of the power source 3; a movable module 6 fixedly mounted on the mounting plate 4; a mounting frame 7 fixedly mounted on the movable module 6; a polishing machine 8 fixedly mounted on the mounting frame 7; a limiting rod 5 for limiting the mounting plate 4, the bottom end of the limiting rod 5 being fixedly connected to the mounting plate 4, and the limiting rod 5 being slidably mounted on the mounting cover 2; and a fixing component for fixing plastic products.

[0024] Before grinding the plastic product, the plastic product is first fixed. The fixing components include: a support plate 9 set inside the fixing cover 14; a positioning seat 10 fixedly installed on the support plate 9; a mounting groove opened on the positioning seat 10, and the multiple mounting grooves are evenly distributed in a ring around the circumference of the positioning seat 10; a power source 12 fixedly installed in the mounting groove; and a clamping plate 13 fixedly installed on the movable end of the power source 12, the clamping side of the clamping plate 13 being arc-shaped and closely attached to the inner wall of the plastic product.

[0025] Specifically, the plastic product is placed on the positioning seat 10, and the positioning seat 10 matches the inner cavity structure of the plastic product, so that the bottom of the plastic product abuts against the support plate 9. Through the setting of the positioning seat 10, the plastic product can be quickly positioned, which is convenient for subsequent clamping and fixing.

[0026] At this time, the second power source 12 is activated to move the clamping plate 13, so that multiple clamping plates 13 press against the inner wall of the plastic product, thereby clamping and fixing the plastic product and preventing the plastic product from moving during the polishing process and affecting the polishing effect.

[0027] Since the power source 12 and the clamping plate 13 are provided in multiple sets, the inner wall of the plastic product can be clamped from different directions, which greatly improves the fixing effect of the plastic product.

[0028] Once the plastic product is fixed in place, the power source 3 is activated to move the mounting plate 4 downwards to the set position and then stops. That is, the mounting plate 4 moves from the initial position to the grinding position. At this time, the moving module 6 is activated to move the mounting plate 4, and the mounting frame 7 moves the grinding machine 8, so that the outer side of the plastic product can be ground.

[0029] After the plastic product is polished, start the power source 3 to drive the mounting plate 4 to reset upward, that is, move the mounting plate 4 from the polishing position to the initial position.

[0030] It should be noted that the power source 1 3 is preferably a hydraulic cylinder; the power source 2 12 is preferably a dual-axis cylinder; and the moving module 6 is preferably a three-axis moving module 6, which can drive the grinding machine 8 to move horizontally, vertically, and longitudinally, thereby enabling comprehensive grinding of the outer side of the plastic product.

[0031] Furthermore, the plastic articles in this application are preferably cylindrical plastic articles.

[0032] The cooling mechanism includes: a collection box 17, a pump body 19, and a collection pipe 22 fixedly installed inside the machine base 1; a filter screen 24 slidably installed inside the collection box 17; an air inlet pipe 18 connecting the air inlet end of the pump body 19 and the collection box 17, with the air inlet pipe 18 located above the filter screen 24; a fixed cover 14 fixedly installed on the machine base 1; an annular pipe 15 fixedly installed on the fixed cover 14; and multiple nozzles 16 fixedly installed on the annular pipe 15. 16 are evenly distributed in a ring along the circumference of the annular pipe 15, and multiple nozzles 16 are connected to the annular pipe 15; the air outlet end of the pump body 19 is connected to the air outlet pipe 20 of the annular pipe 15; the guide pipe 23 is connected to the collection pipe 22 and the collection box 17, and the bottom end of the guide pipe 23 is located below the filter screen 24; multiple through holes 21 are opened on the machine base 1, and the multiple through holes 21 are evenly distributed in a ring along the circumference of the annular pipe 15, and the multiple through holes 21 are connected to the collection pipe 22.

[0033] When polishing plastic products, the pump body 19 is started. The pump body 19 can draw out the gas in the collection box 17 through the air inlet pipe 18 and deliver it to the annular pipe 15 through the air outlet pipe 20. The gas is then sprayed onto the outside of the plastic product through multiple nozzles 16. On the one hand, the plastic waste generated during polishing can be blown away, and on the other hand, the outside of the plastic product can be cooled to prevent the waste from melting and adhering to the surface of the plastic product due to high temperature, which would affect the polishing effect.

[0034] With multiple nozzles (16), the outer surface of plastic products can be thoroughly cleaned by blowing air, improving the cleaning effect.

[0035] At the same time, the gas inside the collection box 17 is extracted, creating a negative pressure inside the collection box 17. This causes the collection pipe 22 to produce a suction effect. At this time, the external airflow carries the waste debris through the through hole 21, the collection pipe 22, and the guide pipe 23 into the collection box 17, thereby achieving rapid collection of waste debris and preventing the waste debris cleaned by blowing from re-adhering to the outside of the plastic product and affecting the polishing effect.

[0036] By setting up the filter screen 24, the waste particles in the gas can be filtered out, so that the waste particles are retained at the bottom of the filter screen 24. The filtered gas is then drawn out again through the air inlet pipe 18, so that the gas sprayed out by the nozzle 16 is clean gas.

[0037] As can be seen from the above, this application uses an upward blowing and downward suction method to clean up waste debris and cool the outer side of the plastic product during the polishing process, which significantly improves the polishing effect.

[0038] It should be added that the fixed cover 14 can be used to shield the waste generated during the polishing process and prevent the waste from flying.

[0039] In addition, the collection box 17 is connected to a cold source, which can cool the gas inside the collection box 17, so that the nozzle 16 sprays out cold air, thereby further improving the cooling effect.

[0040] The fixed assembly also includes: a threaded rod 43 rotatably mounted on the collection box 17; a transmission bevel gear 42 fixedly mounted on the end of the threaded rod 43; a threaded tube 44 threadedly connected to the threaded rod 43, the threaded tube 44 passing through and mounted on the machine base 1, and the top end of the threaded tube 44 fixedly connected to the support plate 9; a connecting rod 25 fixedly mounted on the mounting plate 4, the connecting rod 25 passing through and mounted on the machine base 1; a rotating tube 33 rotatably mounted on the machine base 1, the rotating tube 33 being sleeved on the connecting rod 25; a driving bevel gear 34 fixedly sleeved on the rotating tube 33; a driven bevel gear 35 meshing with the driving bevel gear 34, the driven bevel gear 35 rotatably mounted on the collection box 17; a connecting bevel gear 41 coaxially connected with the driven gear; and the connecting bevel gear 41 meshing with the transmission bevel gear 42.

[0041] The linkage 25 has a groove 11, which is spiral in shape. A slider 50 is fixedly installed inside the rotating tube 33 and slides inside the groove 11.

[0042] A fixed pipe 45 is fixedly installed on the collection box 17. A connecting rod 47 is installed through the fixed pipe 45. The connecting rod 47 is installed through the machine base 1. A piston 46 is fixedly installed at one end of the connecting rod 47. The piston 46 is slidably installed inside the fixed pipe 45. The other end of the connecting rod 47 is fixedly connected to the support plate 9.

[0043] When the mounting plate 4 is in the initial position, the support plate 9 is located outside the fixing cover 14. At this time, the positioning seat 10 is located outside the fixing cover 14, which makes it convenient for workers to put the plastic products to be processed on the positioning seat 10 or to remove the polished plastic products.

[0044] As the mounting plate 4 moves from the initial position to the grinding position, the mounting plate 4 drives the connecting rod 25 to move downward. At this time, the slider 50 moves along the path of the slide groove 11, thereby driving the rotating tube 33 to rotate. The rotating tube 33 drives the driving bevel gear 34 to rotate, the driving bevel gear 34 drives the driven bevel gear 35 to rotate, the driven bevel gear 35 drives the connecting bevel gear 41 to rotate, and the connecting bevel gear 41 drives the transmission bevel gear 42 to rotate, thereby driving the threaded rod 43 to rotate. The threaded rod 43 drives the threaded tube 44 to move, and the threaded tube 44 drives the support plate 9 to move. Through the setting of the fixed rod, connecting rod 47, and piston 46, the support plate 9 can be limited, thereby causing the support plate 9 to move downward along the axial direction of the threaded rod 43. The support plate 9 drives the positioning seat 10 to move downward, thereby driving the plastic product to be processed to move downward into the fixed cover 14.

[0045] When the mounting plate 4 moves from the initial position to the grinding position, the bottom of the support plate 9 abuts against the machine base 1.

[0046] After the plastic product is polished, the mounting plate 4 moves upward from the polishing position to reset, and drives the connecting rod 25 to move upward, which in turn drives the rotating tube 33 to rotate in the opposite direction, and then drives the threaded rod 43 to rotate in the opposite direction, so that the polished plastic product moves upward to the outside of the fixed cover 14, making it easier for the staff to remove the polished plastic product and replace it with the plastic product to be processed.

[0047] The cooling mechanism also includes: an annular groove formed on the positioning seat 10; a capsule 49 fixedly installed in the annular groove; and a liquid guide tube 48 connecting the capsule 49 and the fixed tube 45.

[0048] The space below piston 46 in the fixed tube 45 stores coolant. When the support plate 9 moves downward, that is, when the plastic product moves into the fixed cover 14, the support plate 9 drives the connecting rod 47 to move downward. The connecting rod 47 drives piston 46 to move downward. Piston 46 squeezes the coolant downward, so that the coolant is delivered to the bladder 49 through the liquid guide tube 48, thereby causing the bladder 49 to expand.

[0049] When the plastic product is moved into the fixed cover 14, the bladder 49 expands so that its outer wall is pressed tightly against the inner wall of the plastic product. The coolant can cool the inside of the plastic product, effectively absorbing the heat generated during the polishing process, preventing the plastic product from deforming or being damaged due to overheating, and improving the polishing quality.

[0050] In addition, after the bladder 49 expands and its outer wall is pressed tightly against the inner wall of the plastic product, there is a large frictional force between the bladder 49 and the inner wall of the plastic product, which can prevent the plastic product from rotating and further improve the stability of the plastic product during polishing.

[0051] In this application, by setting up a cooling mechanism, the inner and outer sides of the plastic product can be cooled, and the heat generated during the polishing process can be absorbed and carried away in a timely manner to prevent the plastic product from deforming or being damaged due to overheating, thereby improving the polishing quality.

[0052] It should be noted that a cold source is connected to the fixed pipe 45, which can cool the coolant inside the fixed pipe 45.

[0053] The cooling mechanism also includes: a gas collecting pipe 27 fixedly installed in the machine base 1; a piston 26 slidably installed in the gas collecting pipe 27, with the bottom end of the connecting rod 25 passing through the top end of the gas collecting pipe 27 and fixedly connected to the piston 26; a gas distribution pipe 29 symmetrically rotated and installed in the collection box 17; a nozzle 30 fixedly installed on the gas distribution pipe 29, with multiple nozzles 30 arranged linearly and evenly along the axial direction of the gas distribution pipe 29, and all nozzles 30 communicating with the gas distribution pipe 29; and a guide pipe 28 connecting the gas collecting pipe 27 and the gas distribution pipe 29, with the bottom end of the guide pipe 28 rotatably connected to the end of the gas distribution pipe 29.

[0054] The cooling mechanism also includes: a rotating plate 36 coaxially connected to the driven bevel gear 35; a guide groove 37 formed on the rotating plate 36, the guide groove 37 being a uniformly wavy annular groove; a slide rod 38 slidably installed in the guide groove 37; a linkage rack 39 fixedly installed between the slide rod 38 and the filter screen 24; a linkage gear 40 fixedly sleeved on the air distribution pipe 29, the linkage gear 40 meshing with the linkage rack 39; a fixing strip fixedly installed in the collection box 17; a movable rod 31 installed through the fixing strip, the bottom end of the movable rod 31 being fixedly connected to the filter screen 24; and a linkage spring 32 that drives the filter screen 24 to reset, one end of the linkage spring 32 being fixedly connected to the filter screen 24, and the other end of the linkage spring 32 being fixedly connected to the fixing strip.

[0055] When the connecting rod 25 drives the piston 26 to move downward, it can compress the gas in the gas collecting pipe 27, so that the gas is transported to the gas distribution pipe 29 through the air guide pipe 28, and sprayed onto the filter screen 24 through the nozzle 30. Since the air jet direction is from the top to the bottom of the filter screen 24, the waste debris attached to the bottom of the filter screen 24 can be blown away to prevent the filter screen 24 from being blocked and affecting the filtration effect.

[0056] At the same time, the driven bevel gear 35 drives the rotating plate 36 to rotate, causing the slide rod 38 to move along the path of the guide groove 37, and driving the connecting rack 39 to move. The connecting rack 39 drives the filter screen 24 to move. Under the limiting action of the movable rod 31, the fixed bar, and the connecting spring 32, when the slide rod 38 moves along the path of the guide groove 37, it drives the connecting rack 39 and the filter screen 24 to move up and down reciprocally, thereby causing the filter screen 24 to vibrate. This can shake off the waste attached to the bottom of the filter screen 24, thereby achieving further cleaning of the filter screen 24 and improving the cleaning effect.

[0057] In addition, when the linkage rack 39 moves up and down, it can drive the linkage gear 40 to rotate back and forth, which in turn drives the air distribution pipe 29 to rotate back and forth, which in turn drives the nozzle 2 30 to swing back and forth, expanding the air blowing cleaning range of the nozzle 2 30, realizing comprehensive cleaning of the filter screen 24, and greatly improving the cleaning effect.
