[0020] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0021] Embodiment 1, in combination with Figures 1-2 4, a feeding device for intermediate film production, comprising a bracket 1, a conical barrel 2 and a feed pipe 3; the top of the conical barrel 2 is open, and the outside of the conical barrel 2 is provided with a bracket 1, that is, the conical barrel 2 can be supported by the bracket 1, so that the conical barrel 2 can be set up vertically; the bottom of the conical barrel 2 is provided with a feed pipe 3 for connecting to a negative pressure pipeline, that is, when in use, it can be connected to the suction pipeline of a powder vacuum suction machine through the feed pipe 3; the feed pipe 3 is provided with a vertical pipe 4 vertically passing through the bottom of the conical barrel 2, and the top of the vertical pipe 4 is an inclined The incision structure is that the vertical tube 4 is arranged with a plurality of through holes 5 in an array, that is, when the material ton bag is placed in the conical barrel 2, the material ton bag automatically adapts to the structure of the conical barrel 2 under the action of its own gravity, and at the same time, the oblique incision structure of the vertical tube 4 can pierce the material ton bag, so that the vertical tube 4 can be inserted into the material ton bag, and the powder in the material ton bag can enter the vertical tube 4 along the oblique incision and the through holes 5 at the top of the vertical tube 4, and enter the feeding pipe 3 along the vertical tube 4, and turn on the powder vacuum suction machine to generate negative pressure in the feeding pipe 3, so that the negative pressure feeding operation can be carried out;

[0022] It should be noted that the tip of the oblique cut structure of the vertical tube 4 is provided with a cutting edge, and the rest of the structure is smooth, so as to avoid directly cutting off the bag wall at the opening of the material bag, causing the material bag fragments to be sucked away with the powder;

[0023] The body of the feed pipe 3 is provided with an air inlet 6 opening upward, and a regulating valve is installed at the air inlet 6. If the outside air cannot enter the feed pipe 3, the load on the powder vacuum suction machine will increase, and the powder will accumulate in the pipe, eventually leading to pipe blockage. In this embodiment, the outside air can enter the feed pipe 3 from the air inlet 6, thereby effectively preventing the vertical pipe 4 or the feed pipe 3 from being blocked. At the same time, the operator can control the opening of the air inlet 6 through the regulating valve to prevent the air inlet 6 from being too large, resulting in too low a negative pressure in the feed pipe 3, and affecting the efficiency of negative pressure delivery.

[0024] It should be noted that the powder vacuum suction machine is a mature product on the market, so its specific structure does not need to be described in detail in this embodiment;

[0025] It should be noted that the inlet of the regulating valve is provided with a filter 8 to prevent foreign matter on the outer wall from entering the feed pipe 3 along the air inlet 6;

[0026] During use, the operator can drop the ton bag of materials into the conical barrel 2 through a forklift or lifting equipment. The ton bag of materials automatically adapts to the structure of the conical barrel 2 under the action of its own gravity, thereby forming a conical shape. At the same time, the oblique cut structure of the vertical tube 4 can pierce the ton bag of materials, so that the vertical tube 4 can be inserted into the ton bag of materials. The powder in the ton bag of materials can enter the vertical tube 4 along the oblique cut and the through hole 5 at the top of the vertical tube 4, and enter the feed pipe 3 along the vertical tube 4. The powder vacuum suction machine is turned on to generate negative pressure in the feed pipe 3, and negative pressure feeding operation can be carried out.

[0027] Embodiment 2: Although the above embodiment can perform dust-free negative pressure feeding operation, it is found during use that, because the breach of the material ton bag just fits the body of the vertical tube 4, when there is less material remaining in the material ton bag, the bag wall of the material ton bag directly covers the vertical tube 4 under the action of negative pressure, causing the material ton bag to be firmly adsorbed and difficult to remove. The powder vacuum suction machine needs to be turned off to successfully remove the bag of the material ton bag. In order to solve this technical problem, this embodiment is further improved;

[0028] Combined with Figures 1 to 4 , a feeding device for intermediate film production, which is different from Example 1 in that on the basis of Example 1, as shown in the attached Figure 3 As shown, the vertical tube 4 is provided with a plurality of wedge-shaped expansion plates 7 at intervals along the circumferential direction, that is, when the vertical tube 4 is inserted into the material ton bag, the expansion plates 7 can expand the opening of the material ton bag, and when there is less material remaining in the material ton bag, the outside air can enter the vertical tube 4 from the gap between two adjacent expansion plates 7, thereby preventing the bag of the material ton bag from being firmly adsorbed, and the bag of the material ton bag can be smoothly taken out without shutting down the powder vacuum suction machine;

[0029] The bottom of the conical barrel 2 is provided with a neck portion, that is, when a small amount of material remains in the material bag, the bag of material can be taken out, and the remaining small amount of material can fall into the neck portion of the conical barrel 2 along the broken opening of the material bag, and then be sucked away.

[0030] Embodiment 3, in combination with Figures 1 to 4 , a feeding device for intermediate film production, based on embodiment 1 or 2, the top of the conical barrel 2 is a trumpet-shaped structure, which can facilitate the operator to quickly align the material bag with the open top of the conical barrel 2, so as to smoothly put the material bag into the conical barrel 2;

[0031] In addition, the body of the conical barrel 2 is a thin-walled structure, and a vibration motor can be provided on one side of the body. The vibration motor can vibrate the body of the conical barrel 2, thereby vibrating the powder in the material bag, thereby accelerating the falling of the powder and further improving the efficiency of negative pressure feeding.

[0032] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
