Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a conveyor belt device for injection molding boxes and injection molding production equipment. Background Technology

[0002] In the material output process of injection molding machines, existing technologies simply place a single receiving box fixed below the end of the discharge conveyor belt to receive and collect the material. There is no dedicated box transfer device adapted to the material output of injection molding machines. Therefore, after the receiving box is full, it must be manually replaced promptly. Full boxes of molded material are usually heavy, and manual handling is labor-intensive and inconvenient. Under single-person operation, it is difficult to simultaneously manage the receiving and box changing of multiple injection molding machines. Failure to replace a full box in time forces the injection molding machine to stop, hindering continuous production and directly impacting overall production efficiency. Furthermore, manual box changing is prone to material spillage due to operational errors and delayed reception, resulting in waste. The entire process requires manual monitoring of the receiving status, indicating low equipment intelligence. This increases labor costs and fails to meet the demands of efficient, continuous, and low-labor-input injection molding production.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Example 1: See Figure 1 and Figure 3 As shown, Embodiment 1 of this application provides a conveyor belt device for injection molding boxes, including: a conveyor belt body 1, a drive component 2, a conveyor belt control box 3, two position sensors 4, and an alarm device (not shown). The conveyor belt body 1 includes two rails 11 and multiple rollers 12. The two rails 11 are spaced apart and arranged parallel to each other. Each roller 12 is located between the two rails 11 and is rotatably connected to the rails 11. The rollers 12 are arranged sequentially at intervals along the length direction of the rails 11. The conveyor belt body 1 sequentially forms an empty box position 13, a receiving position 14, and a full box position 15 along its length direction. The empty box position 13, the receiving position 14, and the full box position 15 can all accommodate a box 8. The drive component 2 is disposed at the end of one of the rails 11 and is in transmission cooperation with each of the rollers 12. The conveyor belt control box 3 is disposed at the end of one of the rails 11 and is located on the side of the rail 11 away from the rollers 12. The drive component 2 is electrically connected to the conveyor belt control box 3. Both position sensors 4 are connected to the conveyor belt body 1, and the two conveyor belt control boxes 3 are located at the empty box position 13 and the full box position 15, respectively. Both position sensors 4 are electrically connected to the conveyor belt control box 3. The alarm device is electrically connected to the conveyor belt control box 3. The injection molding box conveyor belt device of this application can be set below the discharge end of the injection molding machine 7. In the initial state, one material box 8 is placed at the empty box position 13 and the receiving position 14. The material box 8 at the receiving position 14 is directly facing the discharge port of the injection molding machine 7, and the material can fall directly into the material box 8 at the receiving position 14. When the injection molding machine 7 detects that the output amount has reached the set value, it sends a signal to the conveyor belt control box 3. The conveyor belt control box 3 then drives the roller 12 to rotate, moving the material box 8 along the rail 11 and transferring the material box 8 from the receiving position 14 to the full position 15. During this process, the position sensor 4 located at the full position 15 determines whether the material box 8 is accurately positioned by checking if it is blocked by the material box 8. After the receiving position 14 is vacated, the material box 8 from the empty position 13 will be simultaneously moved to the receiving position 14 and confirmed to be in place by the position sensor 4 at the receiving position 14 to continue receiving materials. After the empty position 13 is vacated, a new empty box needs to be manually replenished in a timely manner. If the position sensor 4 of the empty position 13 detects a new empty box, the alarm device will not be triggered; if no empty box is detected for a long time, the conveyor belt control box 3 will activate the alarm device to prompt for replenishment. Meanwhile, the full bin 8 at the full bin position 15 also needs to be removed manually in a timely manner. If the position sensor 4 at the full bin position 15 detects that the bin 8 has not been moved for a long time, the conveyor belt control box 3 will also trigger the alarm device to remind the staff to handle it.

[0053] The conveyor belt of the injection molding box 8 in this application, through the linkage of the conveyor belt body 1 with empty box position 13, material receiving position 14 and full box position 15, and the drive component 2, conveyor belt control box 3, position sensor 4 and alarm device, realizes automatic displacement, replenishment and status monitoring of the box 8. It eliminates the need for full-time manual supervision and handling of full box materials, effectively avoids the problem of injection molding machine 7 downtime caused by untimely box changing, reduces material waste during manual box changing, significantly reduces manual labor intensity, improves production efficiency and equipment intelligence level, reduces production labor costs, and solves the defects of existing technology such as high labor consumption, poor production continuity and easy material waste.

[0054] In one possible implementation, the conveyor belt body 1 includes a connecting beam 16 located between and connected to the two rails 11. Two position sensors 4 are respectively mounted on the corresponding connecting beams 16. The connecting beam 16 enhances the overall structural rigidity of the conveyor belt body 1, preventing deformation or spacing shift of the rails 11 due to the rotation of the roller 12 and the load on the hopper 8, thus ensuring the stability of the hopper 8 during conveying. Simultaneously, mounting the position sensors 4 on the connecting beam 16 avoids the rotation area of ​​the roller 12, preventing detection failure or component damage due to interference with the roller 12. This ensures more accurate and stable detection of the empty hopper position 13 and the full hopper position 15 by the position sensors 4, providing a guarantee for the reliable operation of automatic shifting and replenishment of the hopper 8.

[0055] The connecting beam 16 includes a strip 161 and a transition frame 162. The strip 161 is located directly below a roller 12, and its two ends are respectively connected to corresponding rails 11. One end of the transition frame 162 is connected to the strip 161, and the other end of the transition frame 162 extends into the gap between adjacent rollers 12. The position sensor 4 is disposed at the end of the transition frame 162 opposite to the strip 161. The strip 161 enhances the connection strength and structural stability of the conveyor belt body 1, preventing the rails 11 from deforming or shifting due to load or rotation of the rollers 12. The transition frame extends into the gap between adjacent rollers 12 and installs the position sensor 4, thus accurately avoiding the rotation area of ​​the rollers 12, preventing the position sensor 4 from interfering with the rollers 12 and causing damage, while ensuring the accuracy of detecting the position status of the material box 8.

[0056] The adapter frame 162 includes a horizontal plate 1621 and a vertical plate 1622. The horizontal plate 1621 is attached to the strip 161 and is perpendicular to the strip 161. The vertical plate 1622 is perpendicular to the horizontal plate 1621 and extends to the gap between the two rollers 12. The position sensor 4 is mounted on the vertical plate 1622. The vertical structure of the horizontal plate 1621 and the vertical plate 1622 allows the position of the position sensor 4 to be more in line with the detection requirements of the material box 8. The extended layout of the vertical plate 1622 also avoids the rotation area of ​​the rollers 12, preventing interference and damage between the position sensor 4 and the rollers 12.

[0057] In one possible implementation, the conveyor belt body 1 includes multiple support legs 17 connected to the rails 11. A horizontal plate 1621 is located at the bottom of the rails 11 and connected to their lower edge. The roller 12 is located above the horizontal plate 1621. Each support leg 17 provides stable support for the conveyor belt body 1, ensuring the overall structure's stability when carrying the material box 8. The horizontal plate 1621, located at the bottom of the rails 11, strengthens the connection between the rails 11 and the support legs 17 and is arranged in a layered manner with the roller 12, preventing interference from the rotation of the roller 12. The vertical plate 1622 carries the position sensor 4 and extends to the gap of the roller 12, precisely avoiding the rotation area of ​​the roller 12, ensuring the accuracy and stability of the position sensor 4's detection of the material box 8's status.

[0058] In one possible implementation, the drive component 2 has a rotating shaft 21. Adjacent rollers 12 are driven by a chain 5, causing them to rotate synchronously and in the same direction. This ensures the smooth transport of the material box 8 on the conveyor belt body 1, preventing jamming or displacement. The rotating shaft 21 of the drive component 2 is connected to a sprocket 6. The sprocket 6 and the rollers 12 at the ends are driven by the chain 5, achieving efficient power transmission and ensuring the stability of the conveyor belt operation. The rotating shaft 21 of the drive component 2 is perpendicular to the rail 11, optimizing the installation space layout of the drive component 2, avoiding interference with other structures of the conveyor belt body 1, and precisely matching the power transmission direction with the conveying direction of the material box 8, thus improving overall transmission efficiency.

[0059] In one possible implementation, the conveyor belt control box 3 is supported on the rail 11 on which the drive component 2 is mounted. A baffle plate 31 is connected to the conveyor belt control box 3, extending to the side of the sprocket 6 opposite to the drive component 2. The baffle plate 31 effectively protects the operating chain 5, preventing external debris from getting caught in the chain 5 and affecting transmission stability, and preventing accidental contact with the rotating chain 5 by personnel, thus improving the safety and reliability of the injection molding box conveyor belt device of this application.

[0060] The bottom of the conveyor belt control box 3 is provided with support legs 17. The support legs 17 and the drive component 2 are staggered to avoid installation space conflicts and ensure that the layout of each component is compact and that they do not interfere with each other during operation. The support legs 17 on the conveyor belt control box 3 and the support legs 17 on the rail 11 are located in the same plane. This allows for more uniform force distribution and improves the structural stability of the injection molding box conveyor belt device of this application during placement and operation.

[0061] In one possible implementation, the thickness direction of the conveyor belt control box 3 is parallel to the rail 11, which can effectively reduce the space occupied by the control box in the direction perpendicular to the rail 11, reduce the obstruction of the injection molding machine 7, facilitate the daily operation, inspection and maintenance of the injection molding machine 7 and the injection box conveyor belt device of this application, and make the overall equipment layout more compact and reasonable.

[0062] Example 2: Figure 2 As shown, Embodiment 2 of this application also provides an injection molding production device, including: an injection molding machine 7 and an injection molding box conveyor belt device as described above. The injection molding machine 7 includes a main unit 71 and a discharge conveyor belt 72 disposed on the main unit 71. The conveyor belt body 1 of the injection molding box conveyor belt device is perpendicular to the discharge conveyor belt 72 and located below the discharge conveyor belt 72. The conveyor belt control box 3 is located on one side of the injection molding machine 7 perpendicular to the discharge conveyor belt 72. This layout is compact and reasonable, and can effectively avoid operational interference between the material box 8 and the discharge conveyor belt 72. The conveyor belt control box 3 and the injection molding machine 7 are connected via cable communication. When the injection molding machine 7 detects that the material output of the discharge conveyor belt 72 has reached the set value, it sends a signal to the conveyor belt control box 3. The conveyor belt control box 3 then drives the roller 12 to rotate, moving the full box 8 of the receiving position 14 to the full box position 15, and simultaneously filling the empty box of the empty box position 13 to the receiving position 14. After the empty box is accurately in place, the conveyor belt control box 3 will send a signal to the injection molding machine 7. After receiving the signal, the injection molding machine 7 can start the next round of material discharge operation, realizing the automated linkage operation of injection discharge and box 8 movement, and improving production efficiency.
