Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, and in particular relates to a deburring device for plastic processing. Background Technology

[0002] Plastic deburring refers to the process of removing burrs generated during the molding, cutting, or processing of plastic products through physical, chemical, or mechanical methods to improve the surface quality and precision of the products. Burrs are irregular protrusions on the edges or surfaces of plastic parts, which can affect the appearance and function of the parts. Common burr removal methods include manual grinding, vibratory grinding, sandblasting, heat treatment, and chemical treatment. Deburring not only ensures that parts can be assembled smoothly, but also extends their service life to a certain extent. Therefore, it is widely used in the production of automobiles, electronics, medical devices, and other fields. Plastics are typically deburred using a grinding process, where the item to be ground is placed under the grinding assembly. However, this method has limited positioning effectiveness, making the item prone to slipping during grinding. This requires redeployment before subsequent processing, resulting in wasted time and impacting the efficiency of deburring plastic products. To address this, we propose a deburring device for plastic processing. Utility Model Content

[0003] The purpose of this invention is to provide a deburring device for plastic processing. Specifically, by setting a positioning component, a motor is started to drive a geared disc to rotate counterclockwise. This causes the geared disc to move four sliders through an arc groove, bringing four L-shaped clamps closer together. Then, a push rod is activated to push a cross-shaped protrusion upwards. This positioning of the item to be deburred at the top center of the cross-shaped protrusion by the proximity of the four L-shaped clamps prevents displacement and redeployment during grinding, reducing wasted time and ensuring efficient deburring of plastic products. This invention solves the problem that existing plastic deburring processes typically use grinding, placing the item below the grinding component. However, this method has limited positioning effectiveness, making the item prone to slipping during grinding and requiring redeployment for subsequent processing, thus affecting the efficiency of deburring plastic products.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a deburring device for plastic processing, including a deburring mechanism. The deburring mechanism is used to grind the outer wall of the plastic to remove burrs on the outer wall of the plastic. The deburring mechanism includes a horizontal plate and a storage box. A bottom cover is installed at the bottom of the horizontal plate, a top cover is installed at the top of the horizontal plate, and a grinding wheel is installed at the center of the top of the top cover. The storage box is located at the bottom of the bottom cover. Square slots are provided on the left and right sides of the rear side of the top outer wall of the storage box. A conduit is installed on the inner wall of the square slot of the storage box. The top of the conduit passes through the bottom cover and the horizontal plate and extends upward into the interior of the top cover. The bottom of the grinding wheel extends downward into the interior of the top cover. Four hollow protrusions are provided on the outer side of the top of the grinding wheel.

[0005] Furthermore, the deburring mechanism includes a positioning component, which is used to fix the item to be deburred in the center inside the positioning component. A splitting component is disposed at the bottom of the positioning component, and the splitting component is used to collect burrs and debris generated when the positioning component is working. The bottom of the positioning component abuts against the top of the splitting component.

[0006] Furthermore, the positioning component includes a toothed disc, which is disposed at the top center of the bottom cover. The top outer wall of the toothed disc contacts the bottom outer wall of the horizontal plate. A gear is meshed with the right side of the front outer wall of the toothed disc. Four support blocks are provided at the bottom of the toothed disc. The four support blocks are arranged in a circumferential array with the toothed disc as the center, and the sides of the four toothed discs that are far apart from each other are all installed on the inner wall of the bottom cover.

[0007] Furthermore, a support plate is installed at the bottom of the gear, the support plate is installed on the inner wall of the bottom cover, and the outer wall of the support plate is installed on the outer walls of two adjacent support blocks. Four arc grooves are opened at the center of the gear, and the four arc grooves of the gear are arranged in a circumferential array with the horizontal plate as the center. Four sliders are provided on the top of the gear. The hatch is hollowed out, and the hollowed-out part of the hatch is made of glass. By making the hollowed-out part of the hatch glass, it is easy for the user to see through the plastic product in the polished state. The bottom of the slider is equipped with a cylindrical protrusion, which extends into the arc groove of the gear plate and is slidably connected. The front of the top cover is rotatably connected to a hatch.

[0008] Furthermore, the top of the top cover has four straight slots, which are X-shaped. An L-shaped clamp is slidably connected to the inner wall of the straight slot. The bottom outer wall of the L-shaped clamp is installed on the top outer wall of the slider. A slide rail is installed inside each of the four hollow protrusions. The top of the L-shaped clamp extends into the hollow protrusion and is slidably connected to the slide rail. The horizontal plate has a circular hole at its center, and a push rod is located at the center of the circular hole.

[0009] Furthermore, the bottom outer wall of the push rod is installed on the center of the bottom of the bottom cover, the top of the push rod extends upward to the inside of the top cover, and a cross protrusion is installed on the top of the output end of the push rod; by setting a fan, it can output airflow to the rearward side, so that the airflow blows the burr debris backward and finally enters the duct. The outer diameter of the cross-shaped protrusion is larger than the inner diameter of the circular hole in the horizontal plate. Fans are installed on the inner walls of the left and right sides of the top cover.

[0010] Furthermore, the splitting assembly includes four cover plates, which are divided into two groups of cover plate assemblies, left and right. The two groups of cover plate assemblies are horizontally mirrored with respect to the storage box as the center. Each group of cover plate assemblies includes two cover plates, which are arranged one in front of the other. The outer side walls of the two cover plates are installed on the outer wall of the storage box. By setting the insertion relationship between the insert rod and the square plate, the insert rod can hook onto the square plate when inserted, and fix the square plate inside the block. Each of the two cover plates has a block underneath it, and the block is installed on the outer side wall of the storage box.

[0011] Furthermore, the interior of the cube is hollow, and a square plate is installed at the bottom of the cover plate, extending downward into the interior of the cube. Slide plates are installed on the opposite sides of the two square plates, and two insert rods are installed at the center of each slide plate. The front and back of each insert rod extend outward through the front and back of the cube and are slidably connected. Springs are fitted around the outer sides of each insert rod. A C-shaped handle allows the user to simultaneously pull both insert rods outward, thereby simultaneously compressing the two springs via the slide plates. The spring is flexibly connected to the inner wall of the block and the slide plate, and a C-shaped handle is installed at the end of the plug rod.

[0012] This utility model has the following beneficial effects: This invention utilizes a positioning component. Specifically, a motor is activated to drive a geared disc to rotate counterclockwise. This causes the geared disc to move four sliders through an arc groove, bringing the four L-shaped clamps closer together. Then, a push rod is activated to push the cross-shaped protrusion upwards. In this way, the four L-shaped clamps are brought closer together, positioning the item to be deburred at the top center of the cross-shaped protrusion. This prevents the item from shifting during grinding and requiring redeployment, reducing wasted time and ensuring high efficiency in deburring plastic products.

[0013] This utility model incorporates a splitting component. Specifically, pulling outwards with a C-shaped handle causes the insertion rod to move outwards, which in turn pulls the slide plate outwards and compresses the spring, thus pulling the insertion rod out of the square plate. This allows the locking relationship between the square plate and the insertion rod to be released by pulling outwards with the C-shaped handle, making it convenient for staff to quickly and promptly handle the burrs and debris collected inside the storage box.

Square slots are opened on the left and right sides of the rear side of the top outer wall of the storage box 121. A guide tube 122 is installed on the inner wall of the square slot of the storage box 121. The top of the guide tube 122 passes through the bottom cover 1121 and the horizontal plate 111 and extends upward to the top cover 112. Inside the 2-section, the bottom of the grinding wheel 1123 extends downward to the interior of the top cover 1122. Four hollow protrusions 1124 are provided on the outer side of the top of the grinding wheel 1123. The deburring mechanism 1 includes a positioning component 11, which is used to fix the item to be ground and deburred in the center of the positioning component 11. A splitting component 12 is provided at the bottom of the positioning component 11 and is used to collect the burr debris generated when the positioning component 11 is working. The bottom of the positioning component 11 and the top of the splitting component 12 abut against each other. The positioning component 11 includes a toothed disc 1131, which is provided at the top center of the bottom cover 1121. The top outer wall of the toothed disc 1131 is flush with the bottom of the horizontal plate 111. The gear 1132 is meshed with the outer wall of the toothed disc 1131 on the right side of the front outer wall. Four support blocks 1141 are provided at the bottom of the toothed disc 1131. The four support blocks 1141 are arranged in a circumferential array around the toothed disc 1131. The sides of the four toothed discs 1131 that are far apart from each other are mounted on the inner wall of the bottom cover 1121. A support plate 1142 is installed at the bottom of the gear 1132 and is mounted on the inner wall of the bottom cover 1121. The outer wall of the support plate 1142 is mounted on the outer walls of two adjacent support blocks 1141. Four arc grooves are formed at the center of the toothed disc 1131, arranged in a circumferential array around the horizontal plate 111. Four sliders 1151 are provided at the top of the toothed disc 1131. A cylindrical protrusion is installed at the bottom of block 1151. The cylindrical protrusion of slider 1151 extends into the arc groove of gear 1131 and is slidably connected. A hatch is rotatably connected to the front of top cover 1122. Four straight slots are opened on the top of top cover 1122. The four straight slots of top cover 1122 are X-shaped. An L-shaped clamp 1152 is slidably connected to the inner wall of the straight slot of top cover 1122. The bottom outer wall of L-shaped clamp 1152 is installed on the top outer wall of slider 1151. Slide rails are installed inside the four hollow protrusions 1124. The top of L-shaped clamp 1152 extends into the hollow protrusions 1124 and is slidably connected to the slide rails. A round hole is opened at the center of horizontal plate 111. A push rod 1161 is set at the center of the round hole of horizontal plate 111.The bottom outer wall of push rod 1161 is mounted on the center of the bottom of bottom cover 1121. The top of push rod 1161 extends upward into the interior of top cover 1122. A cross-shaped protrusion 1162 is mounted on the top output end of push rod 1161. The motor 1143 is started to drive the gear disc 1131 to rotate counterclockwise via gear 1132. This causes the gear disc 1131 to move four sliders 1151 through the arc groove, bringing the four L-shaped clamps 1152 closer together. Then, push rod 1161 is started to push the cross-shaped protrusion 1162 upward. This allows the four L-shaped clamps 1152 to move closer together, thus removing the material that needs to be removed. The burr-laden item is positioned at the top center of the cross-shaped protrusion 1162 to prevent displacement and redeployment during sanding, reducing time waste and ensuring efficient deburring of plastic products. The outer diameter of the cross-shaped protrusion 1162 is larger than the inner diameter of the circular hole in the horizontal plate 111. Fans 1163 are installed on the inner walls of the left and right sides of the top cover 1122. The disassembly assembly 12 includes four cover plates 1231, divided into two groups of cover plates, left and right, horizontally mirrored with respect to the storage box 121. Each group of cover plates includes two cover plates 1231. 31. Two covers 1231 are arranged one in front of the other, and the outer side walls of the two covers 1231 are installed on the outer wall of the storage box 121. A block 1232 is provided below each of the two covers 1231, and the block 1232 is installed on the outer side wall of the storage box 121. The interior of the block 1232 is hollow. A square plate 124 is installed at the bottom of the cover 1231, extending downwards into the interior of the block 1232. A sliding plate is provided on the side of each square plate 124 that is far apart from each other. Two insert rods 125 are installed at the center of the sliding plate, and the front and back of the insert rods 125 penetrate the front and back of the block 1232. Extending outwards and slidingly connected, the outer side of the insertion rod 125 is fitted with a spring 126. Pulling the C-shaped handle 127 outwards causes the insertion rod 125 to move outwards, and the insertion rod 125 pulls the slide plate outwards, compressing the spring 126 and pulling the insertion rod 125 out of the square plate 124. This allows the locking relationship between the square plate 124 and the insertion rod 125 to be released by pulling the C-shaped handle 127 outwards, facilitating the quick and timely handling of burrs and debris collected inside the storage box 121. The spring 126 is flexibly connected to the inner wall of the square block 1232 and the slide plate, and the end of the insertion rod 125 is fitted with a C-shaped handle 127.

[0020] A specific application of this embodiment is as follows: In use, first open the hatch on the front of the top cover 1122, then place the plastic product that needs to be polished and deburred at the top center of the cross protrusion 1162, then start the motor 1143 so that its output end drives the gear 1132 to rotate, and then the gear 1131 rotates through the meshing connection between the gear 1132 and the gear plate 1131. When the gear plate 1131 rotates counterclockwise, it will drive the four sliders 1151 to move closer to each other through the arc groove. When the four sliders 1151 move, they will move along the X-shaped straight groove in the horizontal plate 111, and when the sliders 1151 move, they will drive the L-shaped clamping plate 1152 installed on the top to move, so that the four L-shaped clamping plates 1152 move closer to each other along the slide rail in the hollow protrusion 1124. In this way, the plastic product can be positioned and clamped from the corner, ensuring that the plastic product is at the top center of the cross protrusion 1162. Next, the grinding wheel 1123 is started to enter the working state. Then, the push rod 1161 and the fan 1163 are started. The push rod 1161 pushes the cross-shaped protrusion 1162 to slide upward through the top output end. In turn, the cross-shaped protrusion 1162 pushes the plastic product upward, so that the outer wall of the plastic product that needs to be ground and deburred is released from the grinding wheel 1123. The grinding wheel 1123 will remove the burrs on the outer wall of the plastic product through grinding. These burrs will fall onto the horizontal plate 111, and then flow backward under the action of the rearward wind force of the fan 1163. Finally, they flow into the storage box 121 from the duct 122. Alternatively, cleaning fluid can be placed inside the storage box 121 so that the burrs flowing into the storage box 121 are mixed with the cleaning fluid, so as to prevent the burr debris from flowing back and interfering with the operation of the grinding wheel 1123. Finally, after polishing is complete, turn off the equipment, remove the plastic product and reset the parts, then pull the C-shaped handle 127 outwards, causing the C-shaped handle 127 to pull the two insert rods 125 outwards. As the insert rods 125 move, they will also move the slide plate outwards, squeezing the spring 126. This will pull the insert rods 125 out of the square plate 124, allowing the bottom cover 1121 to be pulled upwards. The bottom cover 1121 will then move the square plate 124 upwards through the cover plate 1231, separating the storage box 121. Then, remove the burrs and debris collected inside the storage box 121 in a timely manner.
