Description

Technical Field

[0001] This application relates to the field of surface treatment equipment technology, and more specifically, it relates to a burr removal device for plastic products. Background Technology

[0002] In the production process of plastic bottle caps, deburring is an important step to ensure product quality, appearance and functionality. Burrs may be generated at mold seams, injection ports, demolding edges, trimming cuts and connecting bridges, etc. If not handled properly, they may affect the normal use of the bottle caps. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a burr removal device for plastic products, including a frame, a clamping mechanism for clamping bottle caps, and a lifting mechanism for moving the clamping mechanism and the bottle caps up and down within the frame. The clamping mechanism includes pneumatic grippers, with a first clamping member and a second clamping member respectively disposed on both sides of the pneumatic grippers. The pneumatic grippers drive the first and second clamping members to clamp the bottle caps. A first anti-slip pad is detachably connected to the other end of the first clamping member, and the first anti-slip pad is flush with the bottle cap. The second clamping member has a side contact, and the other end of the second clamping member is detachably connected to a second anti-slip pad, which contacts the other side of the bottle cap. The bottom of the machine frame is formed with a storage groove for placing the bottle cap, and a sanding belt that contacts the end face of the bottle cap is pasted on one side of the inner wall of the storage groove. The bottom of the machine frame is also provided with a fixed seat, and the fixed seat is provided with a roller that drives the bottle cap to rotate in the storage groove. When the bottle cap rotates in the storage groove, it will synchronously drive the first anti-slip pad and the second anti-slip pad to rotate on the side of the first clamping member and the second clamping member.

[0004] Preferably, the clamping mechanism further includes a first connector and a second connector that are driven to the pneumatic gripper finger, and the first connector and the second connector are respectively located on both sides of the pneumatic gripper finger, and the first clamping member and the second clamping member are respectively tenoned to the other end of the first connector and the second connector.

[0005] Preferably, a first bolt is inserted into the side of the first clamping member, and one end of the first bolt passes through the first clamping member and is threadedly connected to the first anti-slip pad, and the first anti-slip pad causes the first bolt to rotate inside the first clamping member; a second bolt is inserted into the side of the second clamping member, and one end of the second bolt passes through the second clamping member and is threadedly connected to the second anti-slip pad, and the second anti-slip pad causes the second bolt to rotate inside the second clamping member.

[0006] Preferably, the fixed base has an internal clearance groove, and the roller moves within the clearance groove and passes through the clearance groove to contact the bottle cap; the fixed base is provided with a drive motor that drives the roller and its internal rotation, and the drive motor is installed on the side of the fixed base.

[0007] Preferably, the lifting mechanism includes a lifting plate connected to the pneumatic gripper, the lifting plate is located inside the frame, and the top of the frame is provided with a cylinder that drives the lifting plate and the pneumatic gripper to move up and down inside it, and the inner wall of the frame is provided with a slide rail that makes the movement of the lifting plate and the pneumatic gripper more stable.

[0008] In summary, the beneficial effects of this application are as follows:

[0009] 1. Position the bottle cap horizontally between the first and second anti-slip pads, with the cap opening facing the sanding belt. Then, the pneumatic gripper can drive the first and second grippers to move towards the bottle cap simultaneously. The first and second anti-slip pads will move towards the bottle cap synchronously under the action of the first and second grippers until the end faces of the first and second anti-slip pads contact the inner wall and outer surface of the bottle cap, respectively, thus clamping the bottle cap.

[0010] 2. The lifting mechanism drives the pneumatic gripper fingers, along with the bottle cap, to move towards the sanding belt until the bottle cap is located in the storage slot and its cap opening face is in contact with the working surface of the sanding belt. At this point, the roller and the bottle cap are in contact. Finally, the roller is driven to rotate, which will drive the bottle cap to rotate inside the storage slot, causing the cap opening face to continuously rub against the working surface of the sanding belt. This achieves circumferential grinding of the cap opening face, thereby removing the burrs generated by demolding and preventing them from affecting the normal use of the bottle cap. This effectively solves the technical problem that deburring is an important step in ensuring product quality, appearance, and functionality during the production of plastic bottle caps. Burrs may be generated at mold seams, injection ports, demolding edges, trimming cuts, and connecting bridges. If not handled properly, they may affect the normal use of the bottle cap.

[0019] A burr removal device for plastic products, see [link to relevant documentation] Figs. 1 to 3The system includes a frame 1, a clamping mechanism 2 for clamping a bottle cap 11, and a lifting mechanism 3 for moving the clamping mechanism 2 and the bottle cap 11 up and down within the frame 1. The clamping mechanism 2 includes pneumatic grippers 201, and a first gripper 202 and a second gripper 203 are respectively provided on both sides of the pneumatic gripper 201. The pneumatic gripper 201 drives the first gripper 202 and the second gripper 203 to clamp the bottle cap 11. The other end of the second clamping member 203 is detachably connected to a first anti-slip pad 204, which contacts one side of the bottle cap 11. The other end of the second clamping member 203 is detachably connected to a second anti-slip pad 205, which contacts the other side of the bottle cap 11. A storage groove 4 for placing the bottle cap 11 is formed at the bottom of the machine frame 1. A sanding belt 5 that contacts the end face of the bottle cap 11 is pasted on one side of the inner wall of the storage groove 4. A fixing seat 6 is also provided, and the fixing seat 6 is provided with a roller 7 that drives the bottle cap 11 to rotate in the storage groove 4. When the bottle cap 11 rotates in the storage groove 4, it will synchronously drive the first anti-slip pad 204 and the second anti-slip pad 205 to rotate on the side of the first clamping member 202 and the second clamping member 203. As long as the bottle cap 11 is axially horizontally positioned between the first anti-slip pad 204 and the second anti-slip pad 205, so that the opening of the bottle cap 11 faces the sanding belt 5, the pneumatic clamping finger 201 can drive the first clamping member 202 and the second clamping member 203 to move towards the bottle cap 11 at the same time. At this time, the first anti-slip pad 204 and the second anti-slip pad 205 will move towards the bottle cap 11 at the same time under the drive of the first clamping member 202 and the second clamping member 203 until the end face of the first anti-slip pad 204 and the end face of the second anti-slip pad 205 contact the inner wall and the outer surface of the bottle cap 11 respectively, thereby achieving the clamping of the bottle cap 11.Next, the lifting mechanism 3 drives the pneumatic gripper 201, along with the bottle cap 11, to move towards the sanding belt 5 until the bottle cap 11 is located in the storage groove 4 and its cap opening end face is in contact with the working surface of the sanding belt 5. At this time, the roller 7 and the bottle cap 11 are in contact with each other. Finally, the roller 7 is driven to rotate. When the roller 7 rotates, it will drive the bottle cap 11 to rotate inside the storage groove 4, so that the cap opening end face of the bottle cap 11 continues to rub against the working surface of the sanding belt 5, thereby achieving circumferential grinding of the cap opening end face, and thus completing the removal of the burrs generated by demolding on the cap opening end face of the bottle cap 11, avoiding affecting the normal use of the bottle cap 11. This effectively solves the problem of deburring in the production process of plastic bottle caps 11, which is essential to ensure product quality and appearance. Burrs are a crucial aspect of both appearance and functionality. They can occur at mold seams, injection ports, demolding edges, trimming cuts, and connecting bridges. Improper handling can lead to technical problems affecting the normal use of the bottle cap 11. In this embodiment, the first anti-slip pad 204, the second anti-slip pad 205, and the roller 7 are all made of silicone. The outer surface of the roller 7 is formed with anti-slip texture 8. Silicone has good friction, which not only increases the friction between the first anti-slip pad 204, the second anti-slip pad 205, and the bottle cap 11, preventing the bottle cap 11 from shifting position during rotation, but also increases the friction between the roller 7 and the bottle cap 11, preventing the roller 7 from slipping while driving the bottle cap 11 to rotate. This effectively improves the stability of this embodiment.

[0020] The clamping mechanism 2 further includes a first connecting member 206 and a second connecting member 207 that are drivenly connected to the pneumatic gripper finger 201. The first connecting member 206 and the second connecting member 207 are located on both sides of the pneumatic gripper finger 201, and the first clamping member 202 and the second clamping member 203 are tenoned to the other ends of the first connecting member 206 and the second connecting member 207, respectively. A first bolt 208 is inserted into the side of the first clamping member 202, and one end of the first bolt 208 passes through the first clamping member 202 and is threadedly connected to the first anti-slip pad 204. The first anti-slip pad 204 drives the first bolt 208 to rotate inside the first clamping member 202. A second bolt 209 is inserted into the side of the second clamping member 203, and one end of the second bolt 209 passes through the second clamping member 203. The second anti-slip pad 205 is threadedly connected to the second anti-slip pad 205, and the second anti-slip pad 205 drives the second bolt 209 to rotate inside the second clamping member 203. In this embodiment, when the roller 7 drives the bottle cap 11 to rotate inside the storage groove 4, the bottle cap 11 will synchronously drive the first anti-slip pad 204 and the second anti-slip pad 205 to rotate on the sides of the first clamping member 202 and the second clamping member 203, respectively. At this time, the first bolt 208 and the second bolt 209 will synchronously rotate inside the first clamping member 202 and the second clamping member 203 under the drive of the first anti-slip pad 204 and the second anti-slip pad 205. Through the cooperation between the above structures, this embodiment can perform deburring work on different parts of the cap opening end face of the bottle cap 11, effectively improving the practicality of this embodiment.

[0021] The fixed base 6 has a clearance groove 9 formed inside, and the roller 7 moves within the clearance groove 9 and passes through the clearance groove 9 to contact the bottle cap 11; the fixed base 6 is provided with a drive motor 10 that drives the roller 7 and its interior to rotate, and the drive motor 10 is installed on the side of the fixed base 6; the lifting mechanism 3 includes a lifting plate 301 that is driven and connected to the pneumatic gripper 201, and the lifting plate 301 is located inside the frame 1, and the top of the frame 1 is provided with a cylinder 302 that drives the lifting plate 301 and the pneumatic gripper 201 to move up and down inside it, and the inner wall of the frame 1 is provided with a slide rail 303 that makes the movement of the lifting plate 301 and the pneumatic gripper 201 more stable.
