[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a feeding device for plastic film production, including a melting device 1, a first mounting frame 2 fixedly installed on the upper part of the melting device 1, a second mounting frame 4 fixedly installed on the upper part of the first mounting frame 2, a bottom material cylinder 5 disposed on the upper part of the melting device 1, a connecting cylinder 6 sleeved inside the bottom material cylinder 5, and a connecting assembly 3 disposed on the upper part of the melting device 1. The connecting assembly 3 includes a disassembly and assembly mechanism 31 disposed on the upper part of the melting device 1. A stirring mechanism 32 is disposed on the upper part of the melting device 1. The connecting cylinder 6 is fixedly installed with the second mounting frame 4. A material hole is opened at the bottom of the melting device 1. The disassembly and assembly mechanism 31 includes a positioning groove 311 opened at the bottom of the bottom material cylinder 5. A positioning block 312 is snapped into the inner wall of the bottom material cylinder 5. A telescopic connecting pipe 313 is snapped into the bottom of the bottom material cylinder 5 through the material hole. An installation ring 314 is fixedly connected to the outer wall of the telescopic connecting pipe 313. A snap-fit ​​hole 315 is opened at the lower part of the installation ring 314. A sliding groove 316 is opened at the bottom of the bottom material cylinder 5. A sliding rod 317 is fixedly connected to the inner wall of the sliding groove 316. A slider 318 is slidably connected to the outer wall of the sliding rod 317. A first spring 319 is fixedly connected to the inner wall of the sliding groove 316. A connecting rod 3110 is fixedly connected to the bottom of the slider 318. A snap-fit ​​rod 3111 is movably connected to one end of the connecting rod 3110. A limit block is fixedly connected to the bottom end of the snap-fit ​​rod 3111. A second spring 3112 is fixedly connected to the bottom of the connecting rod 3110.

[0030] In this embodiment, the positioning block 312 is fixedly connected to the mounting ring 314, the snap-fit ​​rod 3111 is snapped into the snap-fit ​​hole 315, and the inner side of the connecting rod 3110 is fitted to the bottom of the mounting ring 314. Through the cooperation of the positioning groove 311, positioning block 312, telescopic connecting tube 313, mounting ring 314, snap-fit ​​hole 315, sliding groove 316, sliding rod 317, sliding block 318, first spring 319, connecting rod 3110, snap-fit ​​rod 3111, and second spring 3112, the top end of the telescopic connecting tube 313 can be removed from the bottom of the bottom material cylinder 5, thereby facilitating manual cleaning of the blocked material and facilitating subsequent use of the device.

[0031] Furthermore, one end of the first spring 319 is fixedly connected to the slider 318, the bottom end of the second spring 3112 is fixedly connected to the limiting block, and the bottom end of the telescopic connecting pipe 313 is connected to the melting equipment 1.

[0032] When the telescopic connecting pipe 313 needs to be disassembled, the locking rod 3111 is manually pulled downwards to separate it from the locking hole 315. Then, under the elastic force of the first spring 319, the slider 318 slides outwards in the slide groove 316 via the slide rod 317. This allows the connecting rod 3110, fixedly connected to the lower part of the slider 318, to move the locking rod 3111 away from the bottom of the mounting ring 314. The telescopic connecting pipe 313 can then be manually moved downwards, facilitating the manual cleaning of material blocking the bottom material hole of the bottom material cylinder 5. After cleaning, the material is removed... The top end of the telescopic connecting pipe 313 is manually aligned with the material hole at the bottom of the bottom material cylinder 5, and the positioning block 312 fixedly connected to the upper part of the mounting ring 314 is engaged with the positioning groove 311. Then, the engaging rod 3111 is pulled to drive the connecting rod 3110 to move synchronously, so that the connecting rod 3110 is limited to the bottom of the mounting ring 314. The engaging rod 3111 is then aligned with the engaging hole 315. Under the action of the second spring 3112, the engaging rod 3111 is engaged with the engaging hole 315, thereby fixing the top end of the telescopic connecting pipe 313 to the bottom of the bottom material cylinder 5, thus completing the installation operation.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the feeding device for plastic film production provided by this utility model is, for example... Figures 1 to 5 As shown: The stirring mechanism 32 includes a motor 321 fixedly mounted on the upper part of the second mounting frame 4 via a fixed bracket. A rotating shaft 322 is fixedly connected to the output end of the motor 321. A stirring rod 323 is fixedly connected to the outer wall of the rotating shaft 322. A pressing rod 324 is fixedly connected to the outer wall of the rotating shaft 322 via a rotating rod. A ball bearing 325 is movably connected to the bottom end of the pressing rod 324. An inclined pressing ring 326 is fixedly connected to the bottom of the inner wall of the bottom material cylinder 5. A spiral blade 3210 is fixedly connected to the outer wall of the bottom end of the rotating shaft 322. A solid column 328 is fixedly connected to the bottom of the bottom material cylinder 5. A hollow column 327 is sleeved at the bottom of the solid column 328. A third spring 329 is fixedly connected to the bottom of the bottom material cylinder 5.

[0035] In this embodiment, the rotating shaft 322 is rotatably connected to the second mounting bracket 4 via a bearing, and the ball bearing 325 is in contact with the inclined pressure ring 326. Through the cooperation of the motor 321, rotating shaft 322, stirring rod 323, pressure rod 324, ball bearing 325, inclined pressure ring 326, hollow column 327, solid column 328, third spring 329, and spiral blade 3210, the material can be stirred and conveyed, thereby preventing the material from clogging in the telescopic connecting pipe 313 and affecting the normal use of the device.

[0036] Furthermore, the bottom end of the hollow column 327 is fixedly connected to the upper part of the melting device 1, and the bottom end of the third spring 329 is fixedly connected to the upper part of the melting device 1.

[0037] When feeding, the motor 321 drives the rotating shaft 322 to rotate, which causes the stirring rod 323, which is fixedly connected to the outer wall of the rotating shaft 322, to rotate synchronously. This stirs the material in the bottom material cylinder 5 and the connecting cylinder 6, keeping the material in motion and preventing blockage. The rotation of the rotating shaft 322 also causes the spiral blades 3210 to rotate synchronously, conveying the material downwards and preventing blockage in the telescopic connecting pipe 313, which would affect the normal operation of the device. When the rotating shaft 322 rotates, the pressure rod 324 drives the ball bearings 325 to rotate synchronously. Then, under the action of the hollow column 327, the solid column 328, and the third spring 329, the pressure rod 324 and the inclined pressure ring 326 slide relative to each other, causing the bottom material cylinder 5 and the connecting cylinder 6 to slide relative to each other. This vibrates the material in the bottom material cylinder 5 and further prevents blockage.
