Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] When the existing equipment uses a feeding pipe to suck the raw materials in the aggregate bucket into the feeding bucket, some raw materials will adhere to the inner wall of the aggregate barrel and are difficult to be sucked into the feeding bucket, resulting in the raw materials not being fully used, increasing the production cost and the consumption of raw materials.

[0023] To solve the defects existing in the above-mentioned material suction mechanism during the process of sucking raw materials, please refer to Figures 1 - 5 , a material suction mechanism of a high-pressure blown film machine provided by the present invention can scrape off the raw materials adhering to the inner wall of the aggregate bucket 1, facilitating the material pipe to fully absorb the raw materials and reducing the consumption of raw materials. This material suction mechanism is based on an aggregate bucket 1. A bucket cover 2 is installed at the top of the aggregate bucket 1. A material guiding pipe fitting 3 is installed inside the bucket cover 2. A rotating rod 12 is installed outside the material guiding pipe fitting 3. A scraping disc 5 is slidably connected to the end of the rotating rod 12. The diameter of the scraping disc 5 is adapted to the inner diameter of the aggregate bucket 1. The up and down sliding of the scraping disc 5 can scrape off the raw materials adhering to the inner side wall of the aggregate bucket 1. Electric push rods 6 are fixedly installed on both sides of the top of the rotating rod 12. The output end of the electric push rod 6 is fixedly connected with a scraping plate 7. The scraping plate 7 is slidably sleeved outside the rotating rod 12. When the rotating rod 12 slides downward until the scraping plate 7 contacts the inner bottom wall of the aggregate bucket 1, driving the electric push rod 6 can drive the scraping plate 7 to slide reciprocally. The reciprocal sliding of the scraping plate 7 can continuously push the raw materials on the inner bottom wall of the aggregate bucket 1 towards the edge and the center of the aggregate bucket 1. Driving the rotation of the rotating rod 12 can drive the two scraping plates 7 to rotate along the axis of the aggregate bucket 1, so as to comprehensively push the raw materials adhering to the inner bottom wall of the aggregate bucket 1, concentrate the raw materials on the inner bottom wall of the aggregate bucket 1 at the edge and the center of the aggregate bucket 1. Furthermore, the material guiding pipe fitting 3 can suck the remaining raw materials in the aggregate bucket 1, improving the utilization rate of the raw materials.

[0024] In order to enable the scraping disc 5 to slide downward to scrape off the raw materials on the inner side wall of the aggregate bucket 1, refer to Figure 2As shown in the figure, pressing rods 8 are fixedly connected to both sides of the top of the scraping disc 5. The upper ends of the two pressing rods 8 are jointly installed with a connecting rod 10. The connecting rod 10 is arranged in an arc shape. A positioning block 11 is fixedly installed on one side of the top of the bucket lid 2. A telescopic spring 9 is sleeved outside the pressing rod 8. The telescopic spring 9 is arranged between the bucket lid 2 and the connecting rod 10. Pressing the connecting rod 10 can drive the two pressing rods 8 to slide downward. At this time, the telescopic spring 9 deforms. The pressing rod 8 slides downward to push the scraping disc 5 downward, so that the raw materials on the inner wall of the aggregate bucket 1 can be scraped off. The positioning block 11 is used to determine the sliding distance of the scraping disc 5. When the connecting rod 10 fits with the positioning block 11, the scraping plate 7 contacts the inner bottom wall of the aggregate bucket 1, and then drives the rotating rod 12 to rotate. After the scraping plate 7 finishes pushing the raw materials, release the connecting rod 10. The connecting rod 10 can slide upward and reset by the elastic force of the telescopic spring 9. When collecting the raw materials attached to the inner wall of the aggregate bucket 1 next time, repeat the above steps.

[0025] Since the material guiding pipe fitting 3 is arranged at the central position of the aggregate bucket 1, it is difficult to suck the raw materials at the inner edge of the aggregate bucket 1. To solve this technical problem, refer to Figure 3 As shown in the figure, the connecting ring 31 is rotatably installed inside the bucket lid 2, and a feeding pipe 32 is fixedly installed at the lower end of the connecting ring 31. A side suction port 33 is arranged at the lower end of the feeding pipe 32. The side suction port 33 is arranged obliquely, and the rotating rod 12 slides up and down and is sleeved on the feeding pipe 32. The upper end of the connecting ring 31 is rotatably connected with a conduit 34. The conduit 34 is communicated with the feeding pipe 32. A suction pump (not shown in the figure) is installed on the conduit 34. Driving the suction pump, the feeding pipe 32 can suck the raw materials at the central position of the aggregate bucket 1. The bottom of the feeding pipe 32 is arranged in a horn shape, which can expand the suction range of the feeding pipe 32. The side suction port 33 can suck the raw materials at the edge of the aggregate bucket 1.

[0026] In order to realize the rotation of the rotating rod 12 and enable the scraping plate 7 to comprehensively push the raw materials on the inner bottom wall of the aggregate bucket 1, a driving mechanism 4 is arranged on the bucket lid 2. The driving mechanism 4 includes a servo motor 41. The servo motor 41 is fixedly installed on the top of the bucket lid 2. The servo motor 41 is arranged on one side of the connecting ring 31. The output end of the servo motor 41 is fixedly connected with a first gear 42. A second gear 43 is fixedly sleeved outside the connecting ring 31. The first gear 42 meshes with the second gear 43. Driving the servo motor 41 can drive the first gear 42. The rotation of the first gear 42 can drive the feeding pipe 32 to rotate through the second gear 43. The rotation of the feeding pipe 32 can drive the rotating rod 12 and the scraping plate 7 on the rotating rod 12 to rotate. At the same time, it can also drive the side suction port 33 to rotate, so that the side suction port 33 comprehensively sucks the raw materials at the inner edge of the aggregate bucket 1.

[0027] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common general knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and circuit connection of the present utility model will not be explained in detail herein.

[0028] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
