Description

Technical Field

[0001] This invention relates to the field of injection molding processing technology, specifically to a device for processing and recycling waste material with burrs on the edges of injection molded parts. Background Technology

[0002] Deburring of injection molded parts is a common post-processing step. When processing injection molded parts of a specific shape, it is necessary to process the various edges and corners of the injection molded parts, including the front and back sides. Therefore, it is necessary to flip the injection molded parts. The process usually involves first placing the injection molded parts on a platform to remove burrs, and then flipping the injection molded parts to another station to remove burrs using another deburring device.

[0003] In the existing technology, when removing burrs from injection molded parts of a specific shape, multiple stations and multiple burr removal devices are usually required. The burr removal speed is slow, and it is difficult to collect burr waste from multiple stations. Multiple platforms need to be used for burr collection and processing, which leads to low processing efficiency of the processing platform. Summary of the Invention

[0004] The purpose of this invention is to provide a device for processing and recycling waste material from the edge of injection molded parts.

[0005] The technical problem solved by this invention is to address the difficulty in burr collection caused by the use of multiple processing platforms for flipping workpieces in the prior art.

[0006] The present invention can be achieved by the following technical solution: a device for processing and recycling waste burrs on the edge of injection molded parts, including a floating support platform for stacking the parts to be processed, and the floating support platform is located inside the processing equipment. The processing equipment is also provided with a grinding end, which is installed at the output end of a grinding motor. The position of the grinding motor is adjustable. The processing equipment is provided with a transfer mechanism for transferring the parts to be processed and rotating them to ninety degrees.

[0007] A further technical improvement of the present invention is that: a support base plate is fixed inside the processing equipment, a hydraulic cylinder is fixed on the support base plate, and a floating support platform is installed at the output end of the hydraulic cylinder.

[0008] A further technical improvement of the present invention is that: the grinding motor is installed at the output end of the grinding telescopic rod, the grinding telescopic rod is installed at the output end of the transverse screw assembly, the transverse screw assembly is installed at the output end of the longitudinal screw assembly, the fixed end of the longitudinal screw assembly is installed on the top rotating seat, and the top rotating seat is installed at the output end of the processing motor.

[0009] A further technical improvement of the present invention is that the transfer mechanism includes a half gear, which is rotatably mounted on a fixed base via a connecting frame. The fixed base is fixedly mounted inside the processing equipment. A drive motor is rotatably mounted on the fixed base. The drive motor and the half gear are meshed and connected. An adsorption end for negative pressure adsorption of the workpiece is fixed at the end of the half gear.

[0010] A further technical improvement of the present invention is that: a connecting rod is fixedly installed on the fixed base, a fixed limiting base plate is fixed on the connecting rod, a supporting base plate for limiting the workpiece to be processed is provided on the fixed limiting base plate, and a supporting mating groove for cooperating with the workpiece to be processed is provided on the supporting base plate.

[0011] A further technical improvement of the present invention is that: a first limiting plate is fixed on the fixed limiting base plate, a first cylinder is fixed on the side of the fixed limiting base plate, and a clamping plate for supporting and limiting the other end of the supporting base plate is fixed at the output end of the first cylinder.

[0012] A further technical improvement of the present invention is that: a second cylinder is fixed on the support base plate, a limit plate is fixed on the output end of the second cylinder, a mounting top plate is fixed on the connecting rod, and a matching slider for limiting the support base plate is provided on the mounting top plate.

[0013] A further technical improvement of the present invention is that a top base is fixed on the mounting plate, and a top groove is provided on the top base. The slider is slidably installed inside the top groove by means of a top spring, and the top spring is a tension spring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This application combines an innovative transfer mechanism (half-gear, adsorption end) with a multi-axis movable grinding end, enabling the removal of burrs from both sides of a workpiece within a single machine. It eliminates the need to transfer workpieces between multiple stations or use multiple machines, completely solving the problems of long production cycles and low efficiency caused by workpiece flipping in traditional methods. This significantly improves processing efficiency. Therefore, all grinding processes in this application are completed inside a sealed processing device, and all generated burr waste naturally falls off and collects at the bottom of the device. This design achieves unified and automatic waste collection, avoiding the cumbersome cleaning of multiple platforms, greatly improving the working environment, reducing dust pollution, and providing significant convenience for centralized waste recycling and disposal, thus reducing overall costs.

[0015] 2. The device in this application is designed with a precision support base plate, a limiting system (first limiting plate, clamping plate, limiting plate, matching slider, etc.) and a negative pressure adsorption end, which can provide stable and adaptive support and clamping during workpiece transfer and flipping. This effectively prevents deformation or vibration of thin-walled or complex parts due to suspension during processing, ensuring the accuracy of burr removal and the consistency of workpiece quality after processing.

[0016] 3. The entire process of this application (workpiece stacking and loading, automatic part removal, 90-degree flipping, double-sided grinding, and unloading) is automatically completed through the coordinated control of hydraulic cylinders, multiple motors, and pneumatic cylinders. This significantly reduces the labor intensity and skill requirements of operators, minimizes quality fluctuations caused by human factors, and achieves automation and intelligence in production. Furthermore, this application highly integrates functions such as loading, flipping, front and back processing, and waste collection into a single equipment unit. Compared to traditional production lines with multiple devices connected in series, the structure is more compact, saving valuable production space. Attached Figure Description

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figure 1-6As shown, a device for processing and recycling waste burrs on the edges of injection molded parts includes a support base plate 1, on which a hydraulic cylinder 2 is fixed. A floating support platform 3 is provided at the output end of the hydraulic cylinder 2. Parts 15 of a specific shape to be processed are stacked on the floating support platform 3. The height of the floating support platform 3 is controlled by the hydraulic cylinder 2. A processing motor is mounted on the frame, and a top rotating seat 8 is provided at the output end of the processing motor. A longitudinal screw assembly 9 is fixedly mounted on the top rotating seat 8. A transverse screw assembly 10 is provided at the output end of the longitudinal screw assembly 9. A grinding base 7 is fixed at the output end of the transverse screw assembly 10. A grinding telescopic rod 6 is fixedly mounted on the grinding base 7. A grinding machine housing 5 is fixed at the output end of the grinding telescopic rod 6. The grinding end 4 is provided at the end. In this application, both the longitudinal screw assembly 9 and the transverse screw assembly 10 are composed of a screw base, a screw, and a screw motor. That is, a screw motor is fixed on the screw base, and a screw is rotatably mounted on the screw base. The screw is driven by the screw motor, and a sliding sleeve is threaded on the screw. The sliding sleeve is slidably connected to the screw base. The sliding sleeve moves as an output end. In use, the position of the grinding telescopic rod 6 can be controlled by the cooperation of the longitudinal screw assembly 9 and the transverse screw assembly 10, so that the grinding telescopic rod 6 can move to the corresponding grinding position. At this time, the grinding end 4 is driven to rotate by the grinding motor inside the grinding machine housing 5, so that the grinding end 4 grinds and removes the burrs on the workpiece 15 to be processed on the floating support platform 3. The burrs obtained fall directly into the interior of the processing equipment.

[0022] As a further embodiment of this application, the processing equipment is equipped with a transfer mechanism that can transfer the workpiece 15 located on the floating support platform 3, so that the workpiece 15 is moved to a vertical position and the back of the workpiece 15 comes into contact with the transfer mechanism. At this time, the processing motor drives the top rotating seat 8 so that the grinding end 4 can act on the inner surface of the workpiece 15 to remove burrs from the back of the workpiece 15. Since the workpiece 15 is in a vertical suspended state, the burrs removed during this process fall directly into the inside of the equipment. When the transfer equipment transfers the workpiece 15, the burrs that adhere to the workpiece 15 during the transfer process also fall into the inside of the processing equipment, which facilitates the unified collection and recycling of the removed burrs.

[0023] Furthermore, the transfer mechanism includes an adsorption end 14, which is installed at the output end of the half gear 19. The half gear 19 rotates around the fixed base 12, which is fixedly installed inside the processing equipment. The half gear 19 is rotatably connected to the fixed base 12 via a connecting frame 11. A drive base 21 is fixed at the end of the fixed base 12, and a drive motor 35 is fixed on the drive base 21. The drive motor 35 drives a drive gear 20, which meshes with the half gear 19. In this process, the drive motor 35 drives the drive gear 20, causing the half gear 19 to rotate around the center of the fixed base 12 due to the meshing action of the drive gear 20 and the half gear 19. This, in turn, causes the adsorption end 14 fixed at the end of the half gear 19 to rotate, thereby enabling the adsorption and transfer of the workpiece 15.

[0024] Since the workpiece 15 is prone to deformation when suspended, affecting the accuracy of burr removal, this application also includes a support base 13. A support groove 24 is provided on the support base 13, through which the half gear 19 passes. In use, when the half gear 19 moves the workpiece 15 to a new position, the workpiece 15 enters the support base 13. The support base 13 supports the bottom of the workpiece 15, facilitating burr removal and maintaining the positional stability of the workpiece 15.

[0025] To achieve the positional engagement between the workpiece 15 and the support base 13, a connecting base 33 is fixed on the half gear 19, and a third cylinder 34 is fixed on the connecting base 33. A limiting hole is provided on the support base 13, wherein the output end of the third cylinder 34 is slidably connected to the limiting hole. In use, when the connecting base 33 moves to the corresponding position under the action of the half gear 19, the third cylinder 34 is activated, causing the sliding block at the end of the third cylinder 34 to enter the interior of the limiting hole, thereby fixing the relative positions of the half gear 19 and the support base 13. At this time, the rotation of the half gear 19 can move the support base 13 to the corresponding unloading position. The support base 13 can achieve stable transfer of the workpiece 15, ensuring stability during the transfer process and ensuring stable unloading of the workpiece 15.

[0026] Furthermore, a connecting rod 18 is fixedly installed on the fixed base 12. A fixed limiting base plate 22 and a mounting top plate are fixed on the connecting rod 18 respectively. A first limiting plate 23 is fixed on the fixed limiting base plate 22. A first cylinder 32 is fixed on the side of the fixed limiting base plate 22. A clamping connecting bracket 27 is fixed to the output end of the first cylinder 32. A clamping plate 28 is fixed to the output end of the clamping connecting bracket 27. The clamping plate 28 and the first limiting plate 23 act on the support base 13 respectively. Under the action of the clamping plate 28 and the first limiting plate 23, the initial limiting function of the support base 13 is realized. That is, when the adsorption end 14 is not in contact with the support base 13, the clamping plate 28 and the first limiting plate 23 realize the initial limiting function of the support base 13.

[0027] To further limit the positioning of the support base 13, a top base 37 is fixed to the mounting plate. The top base 37 has a top groove 36, and a top spring 38 is fixed inside the top groove 36. A mating slider 39 is fixed to the top spring 38, and the mating slider 39 is slidably connected to the top groove 36. Simultaneously, a cylinder base 31 is fixed to the support base 13, and a second cylinder 30 is fixed to the cylinder base 31. A mounting plate 29 is fixed to the output end of the second cylinder 30, and a limit plate 25 is fixed to the mounting plate 29. The limit plate 25 engages with the mating slider 39; that is, during use, the limit plate 25 presses tightly against the mating slider 39, and the mating slider 39, under the action of the top spring 38, compresses the support base 13. When the support base 13 tilts slightly, the bottom of the support base 13 will press against the first limiting plate 23, with the clamping plate 28 as the support point. When the half gear 19 and the support base 13 are released from their respective restrictions, the half gear 19 continues to rotate until the adsorption end 14 at the end of the half gear 19 acts on the workpiece 15 to be processed, transferring the workpiece 15 to the position of the support base 13. At this time, the half gear 19 and the support base 13 are connected and limited. During this process, by placing the support base 13 on the fixed limiting base plate 22, the interference caused by the support base 13 to the workpiece 15 can be avoided. During the transfer of the workpiece 15, the burrs adhering to the workpiece 15 can be shaken off into the interior of the processing equipment, which facilitates the full collection of burrs.

[0028] In use, the present invention utilizes a drive motor 35 to drive a drive gear 20, which, due to the meshing of the drive gear 20 and the half gear 19, causes the half gear 19 to rotate around the center of the fixed base 12, thereby causing the adsorption end 14 fixed at the end of the half gear 19 to rotate, thus enabling the adsorption and transfer of the workpiece 15 to be processed. When the workpiece 15 is transferred to the back processing position, that is, when the connecting base 33 moves to the corresponding position under the action of the half gear 19, the third cylinder 34 is activated, causing the sliding block at the end of the third cylinder 34 to enter the interior of the limiting through hole, thereby fixing the relative positions of the half gear 19 and the support base 13. At this time, the rotation of the half gear 19 can move the support base 13 to the corresponding unloading position. At this time, the support base 13 can achieve the stable transfer of the workpiece 15, ensuring the stability of the transfer process and ensuring that the workpiece 15 can be unloaded stably. The polished workpiece 15 is then unloaded, and the half gear 19 drives the support base 13 to return to its original position. During this process, the second cylinder 30 pushes the limiting plate 25 to gradually adjust the position of the limiting plate 25, so that the limiting plate 25 and the mating slider 39 come into contact, allowing the mating slider 39 to slide inside the top groove 36 until the support base 13 returns to its original position. At this time, the first cylinder 32 controls the longitudinal movement of the clamping plate 28, so that the clamping plate 28 and the first limiting plate 23 initially limit the support base 13. The limiting plate 25 presses tightly against the mating slider 39. At this time, the mating slider 39 is squeezed against the support base 13 under the action of the top spring 38. At this time, the support base 13 will tilt slightly. The bottom of the support base 13 will press against the first limiting plate 23, with the clamping plate 28 as the support point. When the half gear 19 and the support base 13 are released from the corresponding restriction, the half gear 19 continues to rotate until the suction end 14 at the end of the half gear 19 acts on the workpiece 15 to be processed, transferring the workpiece 15 to the position of the support base 13. At this time, the half gear 19 and the support base 13 are connected and limited. During this process, by placing the support base 13 on the fixed limiting base plate 22, the interference caused by the support base 13 to the workpiece 15 can be avoided. During the transfer of the workpiece 15, the burrs adhering to the workpiece 15 can be shaken off into the interior of the processing equipment, which facilitates the full collection of burrs.
