Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to a feeding system for casting film production. Background Technology

[0002] Cast film uses a variety of raw materials, such as linear particles, high-pressure particles, low-pressure particles, metallocene particles, fillers, white masterbatches, and desiccants. The production process of cast film requires the mixing of various raw material particles.

[0003] To ensure feeding accuracy, each raw material needs to be weighed individually, then poured into a feeding hopper, mixed, and fed into the casting film equipment for casting film production. Since there are many types of casting film raw materials, weighing and feeding each one individually is cumbersome and time-consuming, requiring improvement. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a feeding system for cast film production, which can simultaneously weigh and feed multiple raw materials, thereby improving feeding efficiency and automation level.

[0005] To solve the above-mentioned technical problems, the present invention provides a feeding system for casting film production, comprising: a substrate, a transfer cylinder, an electronic scale, a receiving box, an electric valve, and a feeding hopper. The feeding hopper is located below the substrate, the electronic scales are spaced around the feeding hopper, the receiving box is located on the electronic scale, and a guide plate extending obliquely downward to the opening of the feeding hopper is provided in the receiving box. A fixed valve plate is provided on the side of the receiving box adjacent to the feeding hopper, and a valve hole is provided at the bottom of the fixed valve plate above the guide plate. A movable valve plate for blocking the valve hole is provided inside the receiving box. The electric valve is located on the substrate and corresponds to the receiving box. The transfer cylinder is located on the electric valve.

[0006] In a preferred embodiment of the present invention, a support bracket for supporting the feeding box and the electronic platform scale is provided below the substrate.

[0007] In a preferred embodiment of this utility model, the receiving box is provided with a lifting drive device connected to the top of the movable valve plate.

[0008] In a preferred embodiment of this utility model, the lifting drive device is a pneumatic cylinder or a hydraulic cylinder.

[0009] In a preferred embodiment of the present invention, a controller is further included, which is connected to the lifting drive device to perform lifting control.

[0010] In a preferred embodiment of this utility model, the electronic platform scale is connected to a controller for signal transmission, and the controller is connected to an electric valve for opening and closing control.

[0011] In a preferred embodiment of this utility model, the bottom of the electric valve is provided with a material pipe pointing downwards toward the receiving box.

[0012] The beneficial effects of this utility model are as follows: The feeding system for casting film production disclosed in this utility model opens the electric valve and simultaneously transfers the raw materials from multiple intermediate transfer cylinders to the receiving box below for weighing. After reaching the set weight, the electric valve is closed and the moving valve plate is opened, so that the raw materials in the receiving box are transferred to the feeding box through the guide plate, thus automatically completing the feeding and improving production efficiency.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-2 The embodiments of this utility model include:

[0018] like Figure 1The casting film production feeding system shown includes: a substrate 1, a transfer cylinder 5, an electronic scale 4, a receiving box 6, an electric valve 3, a feeding box 9, and a controller 14. The feeding box 9 is located below the substrate 1, and the electronic scales 4 are spaced around the feeding box 9. In this embodiment, a support 7 is provided below the substrate 1 to support the feeding box 9 and the electronic scales 4, ensuring structural stability. By using a circular array of 7-8 electronic scales 4 around the feeding box 9, the weighing of 7-8 types of casting film raw material particles can be performed simultaneously.

[0019] The receiving box 6 is placed on the electronic scale 4, and the electronic scale 4 is used to weigh the receiving box 6 and the cast film raw material particles in the receiving box 6. In this embodiment, the electronic scale 4 is connected to the controller 14 for signal transmission. The controller 14 can be a PLC with a built-in touch screen, which is beneficial to improving the level of automation.

[0020] like Figure 1 As shown, the electric valve 3 is mounted on the substrate 1 and corresponds one-to-one with the receiving box 6. The transfer cylinder 5 is mounted on the electric valve 3 and stores the cast film raw material. A material pipe 2 pointing downwards towards the receiving box 6 is provided at the bottom of the electric valve 3. The controller 14 is connected to the electric valve 3 to control its opening and closing. During feeding, the electric valve 3 is opened, and the raw material in multiple transfer cylinders 5 is transferred to the receiving box 6 below for weighing. Once the predetermined weight is reached, the electric valve 3 is closed to ensure feeding accuracy.

[0021] A guide plate 8 extending obliquely downwards to the opening of the feeding box 9 is provided in the receiving box 6, which facilitates the transfer of cast film raw material particles in the receiving box 6 to the feeding box 9. Figure 2 As shown, guard plates 10 are provided on both sides of the guide plate 8 to prevent raw materials from slipping off from both sides.

[0022] In this embodiment, a fixed valve plate 15 is provided on the side of the receiving box 6 adjacent to the feeding box 9. The bottom of the fixed valve plate 15 is provided with a valve hole 13 located above the guide plate 8. A movable valve plate 12 that blocks the valve hole 13 is provided on the inner side of the receiving box 6 to control the weighing process of the raw materials.

[0023] To improve automation, a lifting drive device 11 connected to the top of the movable valve plate 12 is provided on the receiving box 6. In this embodiment, the lifting drive device 11 is a pneumatic cylinder or a hydraulic cylinder, such as... Figure 2 As shown, the controller 14 is connected to the lifting drive device 11. After weighing is completed, the electric valve 3 is closed, and the lifting drive device 11 drives the moving valve plate 12 to rise, opening the valve hole 13, so that the raw material in the receiving box 6 is transferred to the feeding box through the guide plate, and the feeding is automatically completed.

[0024] In summary, the feeding system for cast film production disclosed in this utility model can automatically weigh multiple cast film raw materials simultaneously, thereby improving feeding efficiency and automation level.
