DETAILED DESCRIPTION
[0046] The technical scheme in the embodiments of the utility model will be described below in a clear and complete manner in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the utility model.
[0047] As Figures 1-4 shown, the embodiment provides a film blowing machine capable of preventing blocking, which comprises a feed hopper 1, an operating box 2, a stirring rod 3, stirring blocks 4, a lifting mechanism and a rotating mechanism. Two stabilizing rods 23 are fixedly connected in the feed hopper 1. The operating box 2 is fixedly connected between the two stabilizing rods 23. The operating box 2 is fixedly connected in the feed hopper 1. A sliding hole is formed in the bottom end of the operating box 2. The stirring rod 3 is rotatably and slidably connected in the sliding hole. The stirring blocks 4 are provided in plurality. The plurality of stirring blocks 4 are fixedly connected to the circumferential surface of the stirring rod 3. Through the cooperation between the feed hopper 1, the operating box 2, the stirring rod 3, the stirring blocks 4, the lifting mechanism and the rotating mechanism, the plastic particles that are pressed together in the feed hopper 1 can be dredged, the blocking phenomenon in the feed hopper 1 can be effectively prevented, the feeding efficiency is improved, and the production effect of the plastic film is improved.
[0048] The lifting mechanism is arranged in the operation box 2 and is used for driving the stirring rod 3 to move up and down. The lifting mechanism comprises a rotating plate 5, a connecting seat 6, a driving rod 7, a transmission assembly and a driving assembly. The bottom end of the driving rod 7 is fixedly connected with a rotating seat 20. The connecting seat 6 is rotatably connected in the rotating seat 20. The rotating plate 5 is rotatably connected at the top end of the stirring rod 3. The connecting seat 6 is rotatably connected at the top end of the rotating plate 5. The bottom end of the driving rod 7 is rotatably connected with the connecting seat 6. The transmission assembly is arranged in the operation box 2 and is used for driving the driving rod 7 to swing. The driving assembly is arranged in the operation box 2 and is used for driving the transmission assembly to move. The transmission assembly comprises a supporting shaft 8, a driving plate 9, a rotating shaft 10 and a rotating ring 11. The supporting shaft 8 is rotatably connected in the operation box 2. The driving plate 9 is rotatably connected on the supporting shaft 8. The rotating shaft 10 is fixedly connected on one side of the driving plate 9. The rotating ring 11 is fixedly connected at the top end of the driving rod 7. The rotating shaft 10 is rotatably connected on the circumferential surface of the rotating shaft 10. The driving assembly comprises a driving wheel 12, a transmission belt 13 and a first motor 14. The driving wheel 12 is provided with two. One of the driving wheels 12 is fixedly connected on the supporting shaft 8. The transmission belt 13 is drivingly connected between the two driving wheels 12. The first motor 14 is installed in the operation box 2. The output end of the first motor 14 is fixedly connected with the other driving wheel 12. Specifically, the first motor 14 drives the driving wheel 12 to rotate. The other transmission wheel is driven to rotate through the transmission of the transmission belt 13. In turn, the supporting shaft 8 and the driving plate 9 are driven to rotate. When the driving plate 9 rotates, the rotating shaft 10 revolves around the center point of the driving plate 9, so as to drive the driving plate 9 to swing while driving the stirring rod 3 and the stirring block 4 to move up and down in a cycle.
[0049] The rotating mechanism is arranged in the operation box 2 and is used for driving the stirring rod 3 to rotate, and the rotating mechanism comprises a rotating gear 15, limiting blocks 16 and a power assembly. The rotating gear 15 is rotationally connected at the sliding hole, and a through hole is formed in the rotating gear 15. The stirring rod 3 is slidingly and rotationally connected in the through hole. The limiting blocks 16 are two in number and are fixedly connected in the through hole. Two sliding grooves matched with the limiting blocks 16 are formed in the circumferential surface of the stirring rod 3. The limiting blocks 16 are slidingly connected in the sliding grooves, respectively. The power assembly is arranged in the operation box 2 and is used for driving the rotating gear 15 to rotate. The power assembly comprises a power rod 17, a power gear 18 and a second motor 19. Two supporting plates 22 are fixedly connected in the operation box 2. The first motor 14 and the second motor 19 are mounted on the supporting plates 22, respectively. Two fixed blocks 21 are fixedly connected in the operation box 2. Rotating holes are formed in the fixed blocks 21, respectively. The power rod 17 is rotationally connected in the rotating holes. The power rod 17 is rotationally connected in the operation box 2. The power gear 18 is fixedly connected at the bottom end of the power rod 17. The power gear 18 is engaged with the rotating gear 15. The second motor 19 is mounted in the operation box 2. The output end of the second motor 19 is fixedly connected with the top end of the power rod 17. Specifically, the second motor 19 drives the power rod 17 to rotate. When the power rod 17 rotates, the power gear 18 is driven to rotate. When the power gear 18 rotates, the rotating gear 15 is driven to rotate. When the rotating gear 15 rotates, the limiting blocks 16 slide in the sliding grooves. Therefore, the stirring rod 3 and the stirring block 4 are also driven to rotate synchronously, so as to drive the plastic particles to be stirred.
[0050] When it is needed to pour the plastic particles into the feeding hopper 1 to prepare for the feeding process, the plastic particles are often pressed by each other due to self-accumulation during the feeding process, and once the pressing is serious, the feeding hopper 1 is likely to be blocked, and the whole production process is affected. Therefore, at this time, the first motor 14 and the second motor 19 are started first. When the first motor 14 is started, it starts to drive the driving wheel 12 to rotate at high speed. Under the tight transmission of the transmission belt 13, the other transmission wheel connected with the driving wheel 12 through the transmission belt 13 is also driven to rotate synchronously. The rotation of the transmission wheel further drives the support shaft 8 connected therewith to rotate, and the rotation of the support shaft 8 promotes the driving plate 9 to rotate. When the driving plate 9 rotates, the rotating shaft 10 connected therewith performs a revolution motion around the center point of the driving plate 9. In the revolution process, the driving plate 9 not only swings regularly with the rotating shaft 10, but also drives the stirring rod 3 and the stirring block 4 connected therewith to perform a cyclic reciprocating lifting motion. At the same time when the first motor 14 drives the above components to move, the second motor 19 also starts to work, and drives the power rod 17 to rotate rapidly. When the power rod 17 rotates, the power gear 18 engaged therewith also rotates. The rotation of the power gear 18 drives the rotating gear 15 engaged therewith to rotate. Since the rotating gear 15 has a special structure, i.e. it has the limiting block 16 sliding in the sliding groove, when the rotating gear 15 rotates, the limiting block 16 cooperates with the sliding groove to drive the stirring rod 3 and the stirring block 4 to rotate synchronously. In this way, the stirring rod 3 and the stirring block 4 are lifted and rotated synchronously, and the plastic particles in the feeding hopper 1 are fully stirred, so that the feeding hopper 1 is prevented from being blocked by the pressing of the plastic particles, and the feeding process can be continuously and smoothly carried out, laying a good foundation for the subsequent production process.
[0051] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
