Description

TECHNICAL FIELD

[0001] The application relates to the field of plastic cup production equipment, in particular to an extruded sheet material ingredient distribution device. BACKGROUND

[0002] In the production process of disposable plastic cups, first, granular main materials are processed through a series of processes to prepare sheet materials, and then the sheet materials are further processed to prepare disposable plastic cups.

[0003] Before the main materials are prepared into sheet materials, the main materials and auxiliary materials need to be drawn into a material tank for processing. In the prior art, the main materials and auxiliary materials are usually used at the same time. Generally, the main materials or auxiliary materials are transported from the material bin to the corresponding material tank by a vacuum suction material feeding mode. The material tank is connected to the feeding inlet of the extruder. According to the preset main material and auxiliary material ratio, the discharge amount of different material tanks is controlled by an automatic feeding system. The use amount of auxiliary materials is much lower than that of main materials. Therefore, the vacuum pump for feeding main materials is used frequently and is often in an overload state. The vacuum pump for feeding auxiliary materials is idle for a long time due to the small amount of auxiliary materials used. Not only the corresponding feeding efficiency is low, but also the production cost is wasted. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the application provides an extruded sheet material ingredient distribution device, which solves the problem of cost waste in the prior art and improves the feeding rate and the utilization rate of vacuum material drawing.

[0005] The application provides an extruded sheet material ingredient distribution device, which adopts the following technical scheme:

[0006] An extruded sheet material ingredient distribution device comprises a material bin assembly, a hopper assembly, a material tank assembly and a material drawing assembly, wherein,

[0007] The material bin assembly comprises a main material bin and an auxiliary material bin, and the main material bin and the auxiliary material bin are arranged adjacently.

[0008] The material tank assembly comprises a main material tank and an auxiliary material tank, and the main material tank and the auxiliary material tank are arranged correspondingly on one side of the main material bin and one side of the auxiliary material bin.

[0009] The hopper assembly comprises a main hopper one, a main hopper two and an auxiliary hopper, the main hopper one and the main hopper two are symmetrically arranged on the top of the main material tank, the main hopper one and the main hopper two are respectively communicated with the main material bin, the auxiliary hopper is communicated with the auxiliary material bin, and the main hopper two is communicated with the auxiliary hopper.

[0010] The material drawing assembly comprises a material drawing part one and a material drawing part two, the material drawing part one is arranged at the communication outlet of the main hopper one and the main material bin, the material drawing part two is arranged at the communication outlet of the main hopper two and the auxiliary hopper, and valves are arranged at both ends of the material drawing part two.

[0011] By adopting the technical scheme, in the process of feeding the material tank, the valve between the second material extracting part and the second main hopper is closed, and the first material extracting part and the second material extracting part are opened to extract material into the first main hopper and the auxiliary hopper. Because the auxiliary material is used slowly and the main material is used quickly, when the auxiliary material tank is full, the main material tank still needs to continue extracting material. At this time, the valve between the second material extracting part and the auxiliary hopper is closed, and the valve between the second main hopper and the second material extracting part is opened to extract material from the main material bin into the second main hopper through the second material extracting part, thereby improving the utilization rate of the second material extracting part, and greatly shortening the whole material extracting process and saving the material extracting time.

[0012] Optionally, the first material extracting part and the second material extracting part are vacuum pumps.

[0013] By adopting the technical scheme, the first main hopper and the main material tank, the second main hopper and the main material tank, and the auxiliary hopper and the auxiliary material tank are closed, and then the vacuum pump is used to extract material from the material bin into the hopper, thereby saving manpower and time.

[0014] Optionally, the first main hopper, the second main hopper and the auxiliary hopper are each provided with a visual window.

[0015] By adopting the technical scheme, the operator can check the main material accumulation in the hopper according to the visual window. When the material in the hopper is enough, the material extracting part is closed, and the material in the hopper is poured into the material tank. The visual window can clearly allow the operator to observe the situation in the hopper, thereby effectively avoiding the occurrence of material blocking and the like.

[0016] Optionally, the communication part between the first main hopper and the main material tank is provided with a sealing part, and the communication part between the auxiliary hopper and the auxiliary material tank is also provided with a sealing part.

[0017] By adopting the technical scheme, the sealing part is used to seal and separate the hopper and the material tank, thereby ensuring that the material extracting part can normally work.

[0018] Optionally, the sealing part includes a push-up air cylinder and a sealing plate. The push-up air cylinder is horizontally arranged on the top of the main material tank and the auxiliary material tank, and the sealing plate is fixedly connected with the push-up end of the push-up air cylinder.

[0019] By adopting the technical scheme, the push-up air cylinder controls the sealing and opening of the sealing plate on the connection part between the material tank and the hopper, thereby having the advantages of convenience and rapidity.

[0020] Optionally, a photoelectric sensor is arranged in the main material tank and the auxiliary material tank, and the photoelectric sensor is electrically connected with the first material extracting part and the second material extracting part.

[0021] Through the above technical scheme, when the material in the material tank accumulates to a certain degree, the material in the material tank will contact the photoelectric sensor installed in the material tank, and the photoelectric sensor transmits a signal to the material extracting member, so as to drive the material extracting member to close, thereby avoiding excessive discharging, ensuring stable operation of the machine, and preventing blockage and other situations.

[0022] Optionally, a material pushing device is arranged in the main material bin and the auxiliary material bin, and the material pushing device comprises a material pushing cylinder and a material pushing plate.

[0023] Through the above technical scheme, when the material in the material tank accumulates to a certain degree, the material in the material tank will contact the photoelectric sensor installed in the material tank, and the photoelectric sensor transmits a signal to the material extracting member, so as to drive the material extracting member to close, thereby avoiding excessive discharging, ensuring stable operation of the machine, and preventing blockage and other situations.

[0024] In summary, the present application has the following beneficial technical effects:

[0025] 1. During the process of charging the material tank, first, close the valve between the second material extracting member and the second main hopper, and open the first material extracting member and the second material extracting member to extract material from the first main hopper and the auxiliary hopper. Since the amount of auxiliary material is small, the main material tank still needs to continue extracting material after the auxiliary material tank is extracted. At this time, close the valve between the second material extracting member and the auxiliary hopper, and open the valve between the second material extracting member and the second main hopper, so as to extract material from the main material bin to the second main hopper through the second material extracting member, thereby improving the utilization rate of the second material extracting member, and greatly shortening the entire extraction process and saving the extraction time.

[0026] 2. When the material in the material tank accumulates to a certain degree, the material in the material tank will contact the photoelectric sensor installed in the material tank, and the photoelectric sensor transmits a signal to the material extracting member, so as to drive the material extracting member to close, thereby avoiding excessive discharging, ensuring stable operation of the machine, and preventing blockage and other situations.

[0027] 3. When the material in the material tank accumulates to a certain degree, the material in the material tank will contact the photoelectric sensor installed in the material tank, and the photoelectric sensor transmits a signal to the material extracting member, so as to drive the material extracting member to close, thereby avoiding excessive discharging, ensuring stable operation of the machine, and preventing blockage and other situations.
