[0002] Thermoplastic resin products refer to products that can be processed into various shapes after the thermoplastic resin is softened by heating. Thermoplastic resin is a type of polymer with thermoplastic properties, that is, it softens and flows when heated, and resolidifies after cooling. This characteristic allows thermoplastic resins to be processed into various shapes by processes such as heating molding, extrusion, and injection molding, and has a high degree of plasticity and reprocessability. Thermoplastic resin products are widely used in various fields, including the automotive industry, electronic appliances, etc. Thermoplastic resin products have the advantages of good processability, light weight, and good chemical resistance. The molding of thermoplastic resin products usually uses special processing equipment.

[0008] The rotation of the inner motor drives the motor wheel to rotate, thereby driving the upper wheel to rotate, thereby driving the intermediate shaft and the half-tooth gear to rotate, the rotation of the half-tooth gear drives the transmission gear and the transmission column to rotate, thereby driving the driving wheel to rotate, when the half-tooth gear is engaged with the transmission gear, the half-tooth gear just disengages from the pinion gear, when the half-tooth gear is engaged with the pinion gear, the half-tooth gear disengages from the transmission gear, the driving wheel rotates to drive the chain to move, and the half-tooth gear drives the transmission gear to rotate each time, so that the connecting frame on the chain moves forward one station, so that the connecting frame moves from the front of the feed hopper to the mold temperature controller, or from the mold temperature controller to the center position of the lower pressing frame, or Move from the center position of the lower press frame to the end of the lower press frame, or from the end of the lower press frame to the upper frame, or from the upper frame to the front of the feed hopper. When the half-tooth gear meshes with the small gear, the rotation of the half-tooth gear drives the small gear to rotate, thereby driving the left transmission wheel to rotate, thereby driving the right transmission wheel and the vertical shaft to rotate through the lower transmission belt, thereby driving the upper gear to rotate, thereby driving the feed gear and the feed turntable to rotate, thereby moving the arc slot block through the convex column. The internal motor will pause for a period of time each time it rotates one circle, so that the molding device located in the mold temperature controller can be fully heated and melted, and the molded product can be cooled between the upper mold and the lower mold.
[0009] Furthermore, the feeding device includes a bracket fixedly mounted on the feed hopper, a feed transfer block is slidably mounted on the bracket, an arc groove block is fixedly mounted on the feed transfer block, the arc groove block and the boss are slidably mounted, a lower switch plate is slidably mounted in the feed transfer block, a switch spring is arranged between the lower switch plate and the feed transfer block, a slope is arranged in the feed transfer block, a discharge trough is arranged in the feed hopper, the discharge trough is located above the slope of the feed transfer block, and in the initial state, the lower switch plate blocks the discharge port of the feed transfer block.

The feed transfer block slides outward and slides the lower switch plate outward together. At this time, the lower mold is located in front of the feed transfer block. During the sliding process, the raw material is always in the feed transfer block. After the lower switch plate contacts the side column, the feed transfer block continues to move forward. Due to the action of the side column, the lower switch plate no longer moves forward, and the switch spring is compressed. At this time, the lower switch plate no longer blocks the discharge port of the feed transfer block. The raw material in the feed transfer block falls from the discharge port into the lower mold, and then the feed turntable continues to rotate, driving the feed transfer block and the arc groove block to slide back to the initial position through the convex column. When the feed transfer block moves forward, the non-inner empty part of the feed transfer block will block the discharge slot of the feed hopper. When the feed transfer block is reset, the material will enter the feed transfer block.

[0013] The raw material enters the lower mold through the feed transfer block. When the chain transports the lower mold and the raw material to the mold temperature controller, the raw material in the lower mold is melted by the mold temperature controller. Then the chain continues to move forward with the connecting frame and the lower mold. Under the action of the lower pressure frame, the upper roller and the descending plate are pressed downward, so that the side column descends along the lower mold, the side column spring is compressed, and pressed into the lower mold through the upper mold, so that the material is formed into a molded product. Then the upper mold temporarily stays in the lower mold to cool the molded product. When the upper roller leaves the bottom of the lower pressure frame, the side column spring rebounds, driving the descending plate and the upper mold to reset, and the molded product stays in the lower mold.
[0014] When the chain drives the connecting frame to the upper ejector frame, the lower ejector block and the ejector plate are lifted up by the upper ejector frame, the ejector spring is compressed, and the ejector plate ejects the molded product in the lower mold, so that the molded product is separated from the lower mold. At this time, the molded product can be taken out.

[0037] The rotation of the inner motor 201 drives the motor wheel 202 to rotate, thereby driving the upper wheel 204 to rotate, thereby driving the intermediate shaft 208 and the half-toothed gear 209 to rotate, and the rotation of the half-toothed gear 209 drives the transmission gear 205 and the transmission column 206 to rotate, thereby driving the driving wheel 207 to rotate.

When the half-toothed gear 209 is engaged with the pinion 210, the half-toothed gear 209 is disengaged from the transmission gear 205. The driving wheel 207 rotates to drive the chain 108 to move.

[0038] like Figure 6-Figure 9 As shown, the feeding device includes a bracket 304 fixedly mounted on the feed hopper 301, a feed transfer block 302 is slidably mounted on the bracket 304, an arc groove block 303 is fixedly mounted on the feed transfer block 302, the arc groove block 303 is slidably mounted with the boss 218, a lower switch plate 305 is slidably mounted in the feed transfer block 302, a switch spring 306 is arranged between the lower switch plate 305 and the feed transfer block 302, a slope is arranged in the feed transfer block 302, a discharge trough is arranged in the feed hopper 301, and the discharge trough is located above the slope of the feed transfer block 302, and in the initial state, the lower switch plate 305 blocks the discharge port of the feed transfer block 302.
[0039] The raw material is put into the feed hopper 301, falls into the feed transfer block 302, and fills the feed transfer block 302. When the feed turntable 217 rotates with the protruding column 218, it will drive the feed transfer block 302 to slide in the bracket 304 through the arc groove block 303. The feed transfer block 302 slides outward and slides outward with the lower switch plate 305. At this time, the lower mold 402 is located in front of the feed transfer block 302. During the sliding process, the raw material is always in the feed transfer block 302. After the lower switch plate 305 contacts the side column 403, the feed transfer block 302 continues to move forward. Due to the effect of the side column 403, the lower open The closing plate 305 no longer moves forward, and the switch spring 306 is compressed. At this time, the lower switch plate 305 no longer blocks the discharge port of the feed transfer block 302. The raw material in the feed transfer block 302 falls from the discharge port into the lower mold 402. Then the feed turntable 217 continues to rotate, driving the feed transfer block 302 and the arc groove block 303 to slide back to the initial position through the convex column 218.

When the chain 108 transports the lower mold 402 and the raw material to the mold temperature controller 105, the raw material in the lower mold 402 is melted by the mold temperature controller 105. Then the chain 108 continues to move forward with the connecting frame 401 and the lower mold 402. Under the action of the lower pressing frame 109, the upper roller 406 and the descending plate 405 are pressed downward, so that the side column 403 descends along the lower mold 402, and the side column spring 404 is compressed and pressed into the lower mold 402 through the upper mold 407, so that the material is formed into a molded product 411. Then the upper mold 407 temporarily stays in the lower mold 402, so that the molded product 411 is cooled. When the upper roller 406 leaves the bottom of the lower pressing frame 109, the side column spring 404 rebounds, driving the descending plate 405 and the upper mold 407 to reset, and the molded product 411 stays in the lower mold 402.
[0043] When the chain 108 drives the connecting frame 401 to the upper ejector frame 110, the lower ejector block 409 and the ejector plate 408 are lifted up by the upper ejector frame 110, the ejector spring 410 is compressed, and the ejector plate 408 ejects the molded product 411 in the lower mold 402, so that the molded product 411 is separated from the lower mold 402, and the molded product 411 can be taken out at this time.
[0044] The working principle of this embodiment is as follows: the rotation of the inner motor 201 drives the motor wheel 202 to rotate, thereby driving the upper wheel 204 to rotate, thereby driving the intermediate shaft 208 and the half-toothed gear 209 to rotate, and the half-toothed gear 209 rotates to drive the transmission gear 205 and the transmission column 206 to rotate, thereby driving the driving wheel 207 to rotate. When the half-toothed gear 209 is engaged with the transmission gear 205, the half-toothed gear 209 just disengages from the pinion 210. When the half-toothed gear 209 is engaged with the pinion 210, the half-toothed gear 209 disengages from the transmission gear 205. The driving wheel 207 rotates to drive the chain 108 to move, and the half-toothed gear 209 drives the transmission gear 205 to rotate each time. , so that the connecting frame 401 on the chain 108 moves forward one station, so that the connecting frame 401 moves from the front of the feed hopper 301 to the mold temperature controller 105, or moves from the mold temperature controller 105 to the center of the lower pressing frame 109, or moves from the center of the lower pressing frame 109 to the end of the lower pressing frame 109, or moves from the end of the lower pressing frame 109 to the upper frame 110, or moves from the upper frame 110 to the front of the feed hopper 301. When the half-toothed gear 209 is meshed with the pinion 210, the half-toothed gear 209 rotates to drive the pinion 210 to rotate, thereby driving the left transmission wheel 211 to rotate, thereby driving the right transmission wheel 213 and the vertical shaft 214 to rotate through the lower conveyor belt 212, thereby driving The upper gear 215 rotates, thereby driving the feed gear 216 and the feed turntable 217 to rotate, thereby moving the arc groove block 303 through the boss 218, and the raw material is put into the feed hopper 301, falls into the feed transfer block 302, and fills the feed transfer block 302. When the feed turntable 217 rotates with the boss 218, it will drive the feed transfer block 302 to slide in the bracket 304 through the arc groove block 303, and the feed transfer block 302 slides outward and slides outward together with the lower switch plate 305. At this time, the lower mold 402 is located in front of the feed transfer block 302. During the sliding process, the raw material is always in the feed transfer block 302. After the lower switch plate 305 contacts the side column 403, The feed transfer block 302 continues to move forward. Due to the action of the side column 403, the lower switch plate 305 no longer moves forward, and the switch spring 306 is compressed. At this time, the lower switch plate 305 no longer blocks the discharge port of the feed transfer block 302. The raw material in the feed transfer block 302 falls from the discharge port into the lower mold 402. Then the feed turntable 217 continues to rotate, driving the feed transfer block 302 and the arc groove block 303 to slide back to the initial position through the convex column 218. When the feed transfer block 302 moves forward, the non-inner hollow part of the feed transfer block 302 will block the discharge slot of the feed hopper 301. When the feed transfer block 302 is reset, the material will enter the feed transfer block 302.The raw material enters the lower mold 402 through the feed transfer block 302. When the chain 108 transports the lower mold 402 and the raw material to the mold temperature controller 105, the raw material in the lower mold 402 is melted by the mold temperature controller 105. The internal motor 201 pauses for a period of time each time it rotates one circle, so that the molding device located in the mold temperature controller 105 can be fully heated and melted, and the molded product 411 can be cooled between the upper mold 407 and the lower mold 402. Then the chain 108 continues to move forward with the connecting frame 401 and the lower mold 402, and under the action of the lower pressure frame 109, the upper roller 406 and the descending plate 405 are pressed downward, so that the side column 403 descends along the lower mold 402, and the side column spring 404 is compressed and pressed into the lower mold 402 through the upper mold 407, so that the material is formed into a molded product 411, and then the upper mold 407 temporarily stays in the lower mold 402, so that the molded product 411 is cooled, and when the upper roller 406 leaves the bottom of the lower pressure frame 109, the side column spring 404 rebounds, driving the descending plate 405 and the upper mold 407 to reset, and the molded product 411 stays in the lower mold 402. When the chain 108 drives the connecting frame 401 to the upper ejector frame 110, the lower ejector block 409 and the ejector plate 408 are lifted up by the upper ejector frame 110, the ejector spring 410 is compressed, and the ejector plate 408 ejects the molded product 411 in the lower mold 402, so that the molded product 411 is separated from the lower mold 402, and the molded product 411 can be taken out at this time.
