Technical Field
[0001] This utility model relates to the technical field of plastic parts processing equipment, and more specifically, to a transition and diversion device for plastic parts processing. Background Technology
[0002] In the field of plastic parts processing, with the continuous improvement of automation, the desprue removal operation after injection molding is mostly completed by robotic arms instead of manual labor, and usually works in conjunction with pick-up devices. When the injection molded part is taken out of the injection molding machine, the robotic arm simultaneously removes the sprue. The injection molded part is then placed on a belt conveyor on one side of the injection molding machine, while the cut sprue material, due to the cutting position and the design of the shielding structure, also falls onto the belt conveyor. The belt conveyor then transports the injection molded part and sprue material forward together. Workers need to remove the injection molded part at the end of the conveyor and place it on another workbench for subsequent inspection, deflashing, collection, and stacking. The sprue material falls freely from the end of the belt into the collection trough below. This traditional design has obvious drawbacks. Workers must constantly monitor the conveying of the injection molded part and remove it in time; otherwise, the injection molded part will fall from the end of the conveyor belt along with the sprue material. This not only increases the labor intensity of workers but also easily leads to product damage due to negligence, affecting production efficiency and product quality.
[0003] Patent application number 202410378192.3 discloses a desprue device for injection molding, which mainly focuses on the operation process of desprueing injection molded parts and realizes the desprue function through a specific structural design; however, it does not provide corresponding solutions for the separation of injection molded parts and sprue material in the subsequent conveying process and how to more efficiently transfer injection molded parts to subsequent processing stages. Utility Model Content
[0004] The purpose of this utility model is to provide a transition diversion device for plastic parts processing, in order to solve the problem mentioned in the background art that when the belt conveyor transports injection molded parts and sprue material forward together, workers need to remove the injection molded parts at the tail end of the conveyor in advance and place them on another workbench for subsequent inspection, deflashing, collection and stacking, while the sprue material falls freely from the end of the belt conveyor into the collection trough below.
[0005] To achieve the above objectives, this utility model provides a plastic parts processing transition and diversion device, including a conveyor belt. An inclined discharge ramp is installed at the discharge end of the conveyor belt. A worktable is provided on the outer side of the lower end of the discharge ramp. Qualified finished products can slide down the discharge ramp onto the worktable. A waste collection trough is provided below the discharge ramp and the worktable. A waste blocking component is provided above the waste collection trough. A weighing plate is provided at the top of the discharge ramp. A weighing sensor is installed at the bottom of the weighing plate. The weighing sensor is used to detect the weight of the material passing on the weighing plate. When the material weight is outside the qualified weight range, the waste blocking component descends, blocking the waste material from falling into the waste collection trough.
[0006] This system uses a conveyor belt to transport plastic parts to the discharge end. The parts pass over a weighing plate at the top of the discharge ramp. A load cell at the bottom of the weighing plate continuously monitors the material's weight and transmits the data to the control system. When the weight of the material is detected to be outside the pre-set acceptable weight range, the control system issues a command to lower the waste blocking component at the top of the waste collection trough, intercepting the substandard material and causing it to fall into the waste collection trough. Material with the acceptable weight continues to slide down the discharge ramp to the worktable.
[0007] Preferably, a support is installed at the bottom of the conveyor belt.
[0008] This support bracket is installed at the bottom of the conveyor belt, providing a stable support structure. Through reasonable mechanical design, the weight of the conveyor belt and the materials it carries is evenly distributed to the ground, ensuring that the conveyor belt remains stable during operation and will not tilt or shake due to uneven force.
[0009] Preferably, a support plate is installed at the top of one end of the conveyor belt near the discharge ramp, and the waste blocking component is fixed on the top side of the support plate.
[0010] This feature involves installing a support plate at the top of the end of the conveyor belt near the discharge ramp, fixing the waste blocking component to the support plate, and creating a reasonable spatial arrangement between the waste blocking component and the conveyor belt and discharge ramp. When the weighing sensor detects non-conforming material, the waste blocking component, supported by the support plate, can accurately block the non-conforming material.
[0011] Preferably, the bottom center of the support plate is provided with a limiting opening for materials to pass through one by one.
[0012] This feature includes a limiting port at the bottom center of the support plate that constrains the passing materials. Its size is designed to allow only a single material to pass through. As the materials move towards the discharge ramp under the drive of the conveyor belt, the limiting port controls the materials to pass through one by one in an orderly manner, preventing multiple materials from rushing into the discharge ramp at the same time and causing blockage.
[0013] Preferably, a buffer pad is installed at the top of the end of the workbench near the discharge ramp, the top of the buffer pad is provided with a ramp, and a support leg is installed at the bottom of the workbench.
[0014] This feature includes a buffer pad at the top of the worktable near the discharge ramp. When a qualified finished product slides onto the worktable, the pad absorbs the impact through its elastic deformation, thus cushioning the fall. The ramp at the top of the buffer pad guides the finished product to slide in a specific direction, allowing it to slide more smoothly into the designated position on the worktable. Support legs at the bottom of the worktable provide stable support, ensuring the worktable remains stable when receiving finished products.
[0015] Preferably, the waste blocking component includes a mounting frame, the inner end of which is fixedly mounted on the top side of the support plate (13), and the outer end of which is equipped with a lifting cylinder, and the bottom output shaft of the lifting cylinder is vertically equipped with a baffle plate.
[0016] The mounting bracket in this waste blocking component provides a mounting platform for the lifting cylinder and the baffle plate. The lifting cylinder controls the vertical extension and retraction of the bottom output shaft, causing the baffle plate to rise or fall. When the weighing sensor detects non-conforming material, the lifting cylinder receives a command from the control system and drives the baffle plate to descend to the appropriate position to intercept the non-conforming material.
[0017] Preferably, a camera is mounted on the bottom of the mounting bracket.
[0018] This device features a camera at the bottom of the mounting frame that captures real-time images of the working area of the waste blocking component. The captured images are then transmitted to the monitoring system or operators, allowing relevant personnel to visually observe the lifting and lowering status of the baffle, the waste blocking situation, and the material transfer status.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In this plastic parts processing transition diversion device, the device uses a weighing sensor at the bottom of the weighing plate to detect the weight of the passing material in real time. When the weight of the material is outside the acceptable range, the waste blocking component descends, which can automatically and accurately block the unqualified waste in the waste collection trough, while qualified finished products slide down to the worktable. Compared with traditional manual sorting, this structural design greatly improves sorting efficiency, reduces labor costs, avoids sorting errors caused by human negligence, and ensures the consistency of finished product quality.
[0021] The support plate installed at the top of the conveyor belt near the discharge ramp has a limiting port at the bottom center that allows materials to pass through one by one, effectively preventing material accumulation and blockage during transmission. This ensures that plastic parts can pass through the discharge ramp in an orderly and stable manner, thus smoothly separating finished products from waste materials and guaranteeing the smooth operation of the entire processing flow.
[0022] The buffer pad installed on the top of the workbench near the discharge ramp not only cushions the falling finished products and reduces surface damage caused by collision, but also helps the finished products slide more smoothly into the designated position on the workbench, facilitating subsequent inspection, deflashing and other operations, and further improving the quality of the finished products.
[0023] The lifting cylinder-driven baffle plate in the waste blocking component features a rapid response and reliable operation. It descends quickly after receiving a signal from the weighing sensor, effectively blocking substandard waste and preventing it from mixing with the finished product. Simultaneously, a camera at the bottom of the mounting frame monitors the waste blocking situation in real time, allowing staff to promptly detect anomalies and further improving the reliability and stability of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] This utility model provides a transition and diversion device for processing plastic parts, such as... Figure 1, Figure 2 As shown, the device includes a conveyor belt 1, with an inclined discharge ramp 12 installed at the discharge end of the conveyor belt 1. A worktable 3 is provided on the outer side of the lower end of the discharge ramp 12. Qualified finished products can slide down the discharge ramp 12 onto the worktable 3. A waste collection trough 4 is provided below the discharge ramp 12 and the worktable 3. A waste blocking component 2 is provided above the waste collection trough 4. A weighing plate 121 is provided at the top of the discharge ramp 12, and a weighing sensor 122 is installed at the bottom of the weighing plate 121. The weighing sensor 122 is used to detect the weight of the material passing on the weighing plate 121. When the weight of the material is not within the qualified weight range, the waste blocking component 2 descends, blocking the waste into the waste collection trough 4. The device also includes a control system. The data from the weighing sensor 122 is transmitted to the control system for analysis. The control system determines whether the waste blocking component 2 should block or open based on the data.
[0033] In operation, conveyor belt 1 transports plastic parts (i.e., injection molded parts and sprue material) to the discharge end. The plastic parts pass over the weighing plate 121 at the top of the discharge ramp 12. The weighing sensor 122 at the bottom of the weighing plate 121 detects the weight of the material in real time and transmits the data to the control system. When the weight of the material is detected to be outside the preset acceptable weight range, the control system issues a command to lower the waste blocking component 2 above the waste collection trough 4 to intercept the unqualified material and make it fall into the waste collection trough 4. The material with the acceptable weight continues to slide down the discharge ramp 12 to the workbench 3, thereby realizing automatic weighing, screening and diversion of plastic parts without the need for manual sorting. This improves sorting efficiency and accuracy, avoids errors and omissions in manual sorting, and ensures that the workbench 3 receives only qualified finished products, thus improving product quality and production efficiency.
[0034] In this embodiment, as Figure 1 As shown, a support frame 11 is installed at the bottom of the conveyor belt 1. The support frame 11 provides a stable support structure for the conveyor belt 1. Through reasonable mechanical design, the weight of the conveyor belt 1 and the materials it carries is evenly distributed to the ground, ensuring that the conveyor belt 1 remains stable during operation and will not tilt or shake due to uneven force. This enhances the stability of the conveyor belt 1, reduces problems such as material falling and poor transmission caused by the shaking of the conveyor belt 1, extends the service life of the conveyor belt 1, and also provides a basic guarantee for the stable operation of the entire diversion device, reducing the frequency and cost of equipment maintenance.
[0035] Specifically, such as Figure 1As shown, a support plate 13 is installed at the top of one end of the conveyor belt 1 near the discharge ramp 12, and a waste blocking component 2 is fixed to the top side of the support plate 13. By fixing the waste blocking component 2 to the support plate 13, the waste blocking component 2 forms a reasonable spatial arrangement with the conveyor belt 1 and the discharge ramp 12. When the weighing sensor 122 detects non-conforming material, the waste blocking component 2, supported by the support plate 13, can accurately block the non-conforming material. This clarifies the installation position of the waste blocking component 2, ensuring its stability and accuracy, enabling it to stably and reliably perform the blocking action, effectively intercepting non-conforming material, and improving the reliability and stability of the diversion device.
[0036] Furthermore, such as Figure 3 As shown, a limiting port 131 for materials to pass through one by one is provided at the bottom center of the support plate 13. In use, the limiting port 131 at the bottom center of the support plate 13 constrains the passing materials, and its size design allows only one material to pass through at a time. When the materials move towards the discharge ramp 12 under the drive of the conveyor belt 1, the limiting port 131 controls the materials to pass through one by one in an orderly manner, avoiding multiple materials from rushing into the discharge ramp 12 at the same time and causing blockage. This structural design realizes the orderly transmission of materials, ensuring that each material can pass through the weighing plate 121 in sequence for weight detection, avoiding problems such as inaccurate weighing and obstruction caused by material accumulation, and ensuring the smoothness and efficiency of the diversion process.
[0037] Furthermore, such as Figure 5 As shown, a buffer pad 31 is installed on the top of the end of the workbench 3 near the discharge ramp 12. The top of the buffer pad 31 is provided with a ramp, and a support leg 32 is installed on the bottom of the workbench 3.
[0038] In use, when a qualified finished product slides onto the worktable 3, its own elastic deformation absorbs the impact force, acting as a buffer. The inclined surface at the top of the buffer pad 31 guides the finished product to slide along a specific direction, allowing it to slide more smoothly into the designated position on the worktable 3. The support legs 32 at the bottom of the worktable 3 provide stable support, ensuring that the worktable 3 remains stable when receiving finished products. This structural design effectively reduces surface damage to finished products caused by collisions during the sliding process, protecting the quality of the finished products; the inclined surface design facilitates finished product positioning and subsequent processing operations; the support legs 32 ensure the stability of the worktable 3, preventing the worktable 3 from shaking and affecting the receiving and subsequent processing of finished products.
[0039] Furthermore, such as Figure 4 As shown, the waste blocking component 2 includes a mounting frame 21. The inner end of the mounting frame 21 is fixedly mounted on the top side of the support plate 13. A lifting cylinder 22 is mounted on the outer end of the mounting frame 21. A baffle plate 23 is vertically mounted on the bottom output shaft of the lifting cylinder 22.
[0040] In use, the mounting bracket 21 in the waste blocking component 2 provides a mounting carrier for the lifting cylinder 22 and the baffle plate 23. The lifting cylinder 22 drives the baffle plate 23 to rise or fall by controlling the vertical extension and retraction of the bottom output shaft. When the weighing sensor 122 detects non-conforming material, the lifting cylinder 22 receives a command from the control system and drives the baffle plate 23 to fall to the appropriate position to intercept the non-conforming material. This structural design utilizes the rapid response and precise control characteristics of the lifting cylinder 22 to achieve rapid lifting and lowering of the baffle plate 23, which can timely and accurately block non-conforming material, ensure effective separation of waste and finished product, and improve the reliability and efficiency of the blocking operation.
[0041] Furthermore, such as Figure 4 As shown, a camera 24 is installed at the bottom of the mounting frame 21. The camera 24 captures real-time images of the working area of the waste blocking component 2 and transmits the images to the monitoring system or operators, allowing relevant personnel to visually observe the lifting and lowering status of the baffle 23, the waste blocking situation, and the material conveying status. This structural design facilitates real-time monitoring of the working status of the waste blocking component 2, enabling timely detection of abnormalities such as baffle 23 malfunction or material blockage, and prompt implementation of appropriate measures to improve the safety and stability of equipment operation, ensuring the continuous and efficient operation of the diversion device.
[0042] In use, the plastic part processing transition diversion device of this utility model first places the plastic part on the conveyor belt 1 after injection molding and the sprue operation completed by the robot. The conveyor belt 1, supported by the bracket 11, transports the plastic part to the discharge end. When the plastic part passes the weighing plate 121 at the top of the discharge ramp 12, the weighing sensor 122 at the bottom of the weighing plate 121 detects the weight of the plastic part in real time and transmits the detection data to the control system.
[0043] The control system is pre-set with a weight range for acceptable plastic parts. When the data transmitted by the weighing sensor 122 shows that the material weight is outside the acceptable range, the control system will immediately issue a command. At this time, the waste blocking component 2 fixed on the support plate 13 receives the command, and its internal lifting cylinder 22 controls the bottom output shaft to drive the baffle plate 23 to descend rapidly, forming a barrier between the discharge ramp 12 and the worktable 3, intercepting the unacceptable material and causing it to fall into the waste collection trough 4 below; if the material weight is within the acceptable range, the baffle plate 23 remains in the rising state, and the acceptable plastic parts continue to slide down the discharge ramp 12 to the worktable 3.
[0044] During the movement of the plastic parts from the conveyor belt 1 to the discharge ramp 12, the limiting port 131 in the middle of the support plate 13 plays a crucial role. The size of the limiting port 131 allows only a single material to pass through, thereby controlling the materials to pass through this position one by one in an orderly manner, avoiding multiple materials from rushing into the discharge ramp 12 at the same time and causing blockage, ensuring that each material can pass through the weighing plate 121 in sequence to receive accurate weight detection, and ensuring the smooth progress of the diversion process.
[0045] When a qualified plastic part slides onto the workbench 3, the buffer pad 31 at the top of the end of the workbench 3 near the discharge ramp 12 absorbs the impact force of the plastic part through its own elastic deformation, thus cushioning the impact and reducing surface damage caused by the collision. At the same time, the ramp at the top of the buffer pad 31 guides the plastic part to slide along a specific direction, allowing it to slide more smoothly into the designated position on the workbench 3. The support legs 32 at the bottom of the workbench 3 provide stable support for the workbench 3, ensuring that the workbench 3 remains stable when receiving finished products, facilitating subsequent operations such as inspection, deflashing, collection, and stacking of the plastic parts.
[0046] The camera 24 at the bottom of the mounting frame 21 captures real-time images of the working area of the waste blocking component 2, transmitting the images of the lifting status of the baffle 23, the waste blocking situation, and the material conveying status to the monitoring system or operators. In the event of a malfunction of the baffle 23 or material blockage, staff can promptly detect and take appropriate measures to address the issue, ensuring the continuous, efficient, and stable operation of the entire diversion device.
[0047] Finally, it should be noted that the electronic components in the camera 24 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between the electrical components in the above working principle to complete the electrical connection. All of these are technologies known in the art.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
