[0033] The embodiment of the present application provides an automatic waste collection and recycling device for a plastic product stamping machine tool. The schematic diagram of the automatic waste collection and recycling device for the plastic product stamping machine tool is asFigure 1-6 As shown in the figure. The automatic waste collection and recycling device for plastic product stamping machine tools includes a stamping table 10. Connecting columns 20 are connected to multiple top corners of the upper surface of the stamping table 10. The top ends of the multiple connecting columns 20 are connected to a support plate 30. An upper die mechanism 40 is connected to the plate body of the support plate 30. A lower die mechanism 50 is provided at the bottom end of the upper die mechanism 40;

[0034] The lower die mechanism 50 includes a lower die 51 connected to the upper surface of the stamping table 10. A waste hopper 52 is inserted at the bottom end of the lower die 51. A waste treatment component 53 is connected inside the waste hopper 52;

[0035] The waste treatment component 53 includes a rotating rod 531 inside the waste hopper 52, and a pushing member 532 and an ejecting member 533 connected to the outside of the rotating rod 531.

[0036] It should be noted that in this embodiment, the stamping table 10 serves as the basic support part of the entire device, providing an installation plane for other components. One end of the connecting column 20 is fixed at multiple top corners of the upper surface of the stamping table 10, and the other end is connected to the support plate 30, building a stable three-dimensional structure. The upper die mechanism 40 is installed on the support plate 30 and can move downward during operation to stamp plastic products placed on the lower die mechanism 50. The lower die mechanism 50 is fixed to the stamping table 10 and is used to carry plastic products to be stamped. After stamping, the waste will fall into the waste hopper 52 inserted at the bottom end of the lower die 51. The waste treatment component 53 in the waste hopper 52 preliminarily sorts the waste for subsequent recycling.

[0037] Optionally, please refer to the appendix Figure 2 and 3 The upper die mechanism 40 includes a cylinder 41 connected to the upper surface of the support plate 30, and an upper die 42 connected to the output end of the cylinder 41. The upper die 42 is located directly above the lower die 51 vertically.

[0038] In this embodiment, the cylinder 41 is fixed to the upper surface of the support plate 30, and its output end is connected to the upper die 42. When the cylinder 41 is started, according to the preset program, the output shaft makes an extending or retracting movement, driving the upper die 42 to make a reciprocating movement in the vertical direction. When the upper die 42 moves downward, it cooperates with the lower die 51 to perform stamping processing on the plastic products therebetween.

[0039] Optionally, please refer to the appendix Figure 3 and 5 The bottom end of the lower die 51 is provided with a sliding groove 511. The groove body of the sliding groove 511 is used for the waste hopper 52 to slide. One end of the waste hopper 52 is provided with an opening 521.

[0040] In this embodiment, a sliding groove 511 is provided at the bottom end of the lower die 51, and the waste hopper 52 can slide along the sliding groove 511. During the stamping process, the generated waste will fall into the waste hopper 52 through the lower die 51. When the waste hopper 52 is full or needs to be cleaned, the operator can pull out the waste hopper 52 along the sliding groove 511. The opening 521 at one end of the waste hopper 52 facilitates the collection of waste and subsequent cleaning. The cooperative design of the sliding groove 511 and the waste hopper 52 greatly simplifies the installation, disassembly, and cleaning processes of the waste hopper 52, reduces the labor intensity of the operator, and significantly improves the convenience of waste collection and treatment.

[0041] Optionally, please refer to the appendix Figure 3 and 4 , the outer surfaces of both ends of the rotating rod 531 are connected with rotating shaft seats 5311 through bearings, and the rotating shaft seats 5311 are connected to the inner surface of the groove body of the sliding groove 511.

[0042] In this embodiment, the outer surfaces of both ends of the rotating rod 531 are connected to the rotating shaft seats 5311 through bearings, and the rotating shaft seats 5311 are fixed on the inner surface of the sliding groove 511. This connection method allows the rotating rod 531 to stably rotate around its own axis within the sliding groove 511, providing rotational support for the pusher 532 and the ejector 533 to ensure their normal operation. The cooperation between the rotating shaft seats 5311 and the bearings effectively guarantees the stability and smoothness of the rotation of the rotating rod 531, reduces the jamming and wear during the rotation process, and further ensures the stable operation of the waste treatment component 53 and improves the waste treatment efficiency.

[0043] Optionally, please refer to the appendix Figure 1 , the lower die 51 is provided with a pushing hole 512 and an ejecting hole 513, the position of the pushing hole 512 corresponds to the position of the pusher 532, and the position of the ejecting hole 513 corresponds to the position of the ejector 533.

[0044] In this embodiment, the lower die 51 is provided with a pushing hole 512 and an ejecting hole 513, which respectively correspond to the positions of the pusher 532 and the ejector 533. When the pusher 532 moves driven by the rotating rod 531, the slag pushing plate 5324 moves to below the pushing hole 512 to prevent waste from accumulating at the bottom of the pushing hole 512. After stamping is completed, the ejector 533 drives the ejecting pin 5334 to eject the processed plastic product through the ejecting hole 513, facilitating the operator to take it. The cooperative design of the pushing hole 512 and the ejecting hole 513 with the waste treatment component 53 accurately completes the actions of preventing waste accumulation and ejecting the product, avoids waste blocking the pushing hole 512, and improves the convenience of production operation.

[0045] Optionally, please refer to the appendix Figure 3, the pusher 532 includes a rotating cylinder 5321 connected to the outer part of the rod body of the rotating rod 531. A guiding groove 5322 is provided on the outer surface of the cylinder body of the rotating cylinder 5321. The top end of the rotating cylinder 5321 is connected with a translation block 5323 through the guiding groove 5322. A slag pushing plate 5324 is connected to the block body of the translation block 5323.

[0046] In this embodiment, when the rotating rod 531 rotates, it drives the rotating cylinder 5321 connected to the outer part of its rod body to rotate synchronously. The guiding groove 5322 on the outer surface of the cylinder body of the rotating cylinder 5321 guides the translation block 5323 to move in the horizontal direction, and the translation block 5323 then drives the slag pushing plate 5324 to move. The slag pushing plate 5324 moves to the lower part of the pushing hole 512 to prevent waste materials from accumulating at the bottom end of the pushing hole 512. Through the coordinated work of the rotating cylinder 5321, the guiding groove 5322, the translation block 5323 and the slag pushing plate 5324, the circular motion of the rotating rod 531 is converted into the linear motion of the slag pushing plate 5324, effectively preventing waste materials from accumulating at the bottom end of the pushing hole 512 and ensuring the smoothness of waste material collection.

[0047] Optionally, please refer to the appendix Figure 3 , the upper surface of the translation block 5323 is slidably connected to the top end of the sliding groove 511. A through hole for the rotating rod 531 to penetrate is provided on the plate body of the slag pushing plate 5324.

[0048] In this embodiment, the upper surface of the translation block 5323 is slidably connected to the top end of the sliding groove 511, providing a stable sliding track for the translation block 5323 and restricting its movement direction. A through hole for the rotating rod 531 to penetrate is provided on the plate body of the slag pushing plate 5324, so that the slag pushing plate 5324 will not be blocked by the rotating rod 531 during translation and can smoothly move to the lower part of the pushing hole 512. The design of the sliding track and the through hole on the flat slag pushing plate 5324 ensures the stability and smoothness of the translation movement of the slag pushing plate 5324, reduces the deviation and jamming during the movement process, and improves the reliability of the function of preventing waste material accumulation.

[0049] Optionally, please refer to the appendix Figure 3 and 4 , the ejector 533 includes a cam 5331 connected to the outer part of the rod body of the rotating rod 531. A guiding groove 5332 is provided on one side surface of the cam 5331 along the edge of the wheel body. A lifting block 5333 is slidably connected in the groove body of the guiding groove 5332. A top pin 5334 is connected to the upper surface of the lifting block 5333, and the top pin 5334 is inserted into the hole body of the ejecting hole 513.

[0050] In this embodiment, when the rotating rod 531 rotates, it drives the cam 5331 connected to the outer surface of its rod body to rotate. The guiding groove 5332 on one side surface of the cam 5331 guides the lifting block 5333 to move up and down in the vertical direction, and the lifting block 5333 then drives the ejector pin 5334 to move up and down. When the ejector pin 5334 moves upward, the waste material in the lower mold 51 is ejected through the ejection hole 513 and falls into the waste hopper 52. Through the coordinated operation of the cam 5331, the guiding groove 5332, the lifting block 5333 and the ejector pin 5334, the circular motion of the rotating rod 531 is converted into the up and down motion of the ejector pin 5334, accurately ejecting the waste material in the lower mold 51 to ensure the comprehensiveness of waste material collection.

[0051] Optionally, please refer to the appendix Figure 3 and 4 One end of the rotating rod 531 extends to the outside and is connected with a worm gear 534, and the top end of the worm gear 534 is meshed and connected with a worm 535.

[0052] In this embodiment, one end of the rotating rod 531 extends to the outside and is connected with a worm gear 534, and the top end of the worm gear 534 meshes with the worm 535. When the worm 535 rotates, through the meshing transmission of the worm gear and worm, it drives the rotating rod 531 to rotate. The worm gear and worm mechanism has a large transmission ratio, which can accurately control the rotation speed of the rotating rod 531. At the same time, its self-locking function can prevent the rotating rod 531 from rotating by itself due to external force after the driving stops, ensuring the stability of the waste material processing component 53.

[0053] Optionally, please refer to the appendix Figure 4 Both ends of the rod body of the worm 535 are connected to the outer surface of the lower mold 51 through bearing seats, and one side surface of the bearing seat is connected with a motor 536, and the output shaft of the motor 536 is connected to the rod body of the worm 535.

[0054] In this embodiment, the motor 536 is fixed on the bearing seat, and its output shaft is connected to the rod body of the worm 535. After the motor 536 is started, the output shaft drives the worm 535 to rotate, providing power for the waste material processing component 53, so that the rotating rod 531 and the pushing member 532 and the ejecting member 533 connected thereto start to work. The motor 536, as a stable power source, realizes the automatic operation of the waste material processing component 53, reduces manual intervention, improves production efficiency and reduces labor costs.

[0055] The specific operation method of the present invention is as follows:

[0056] The cylinder 41 is started, and the output end of the cylinder 41 pushes the upper mold 42 downward to punch the plastic product between the upper mold 42 and the lower mold 51. During the punching process, the waste material falls into the waste hopper 52 through the push hole 512 of the lower mold 51 under the force of gravity and the push of the upper mold 42. After the punching is completed, the cylinder 41 drives the upper mold 42 to reset upward.

[0057] The motor 536 is started, and the motor 536 drives the worm 535 to rotate, and the worm 535 drives the rotating rod 531 to rotate through the worm gear 534. The rotating rod 531 drives the cam 5331 of the ejector 533 to rotate, and the cam 5331 drives the lifting block 5333 to drive the ejector pin 5334 through the guide groove 5332 to eject the processed plastic product in the lower mold 51 through the ejection hole 513, so that the operator can take it out conveniently. At the same time, the rotating rod 531 drives the rotating cylinder 5321 of the pusher 532 through the guide groove 5322 to drive the translation block 5323 to drive the slag pusher plate 5324 to move to the bottom of the push hole 512 to prevent waste from accumulating at the bottom of the push hole 512.

[0058] When the waste hopper 52 is full or needs to be cleaned, the operator can draw out the waste hopper 52 along the sliding slot 511 for processing.

[0059] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
