TECHNICAL FIELD

[0001] The application relates to the technical field of stone paper production, in particular to a screen changer structure for a stone paper production line. BACKGROUND

[0002] Traditional paper production is generally wasteful of trees and produces more pollutants during the production process, while stone paper is a relatively environmentally friendly paper, the main raw material of which is stone, which is ground into particles or powder and then mixed with some plastic, resin and the like, and the entire production involves many processes and equipment, such as granulating equipment and internal mixing equipment.

[0003] In the papermaking process, the mixed raw materials in a molten state are generally formed into the required paper through a mold. Considering that the mixed raw materials contain some impurities or large particles, a filter plate is generally arranged on the raw material inlet and outlet channel.

[0004] At present, the filter plate is generally installed on the raw material inlet and outlet channel of the mold through screws, and needs to be disassembled and cleaned every time, and then reinstalled, which is relatively time-consuming and laborious. CONTENT OF THE INVENTION

[0021] Optionally, the filter plate can pass through the mold along both sides of the sliding direction of the filter plate.

[0022] By adopting the technical scheme, the flexibility of disassembly and assembly of the filter plate is further improved.

[0023] Optionally, the filter plate pushing assembly comprises a connecting rod, a connecting plate and a telescopic driving piece, one end of the connecting rod is connected with the mold, the other end of the connecting rod is fixedly connected with the connecting plate, the telescopic driving piece is installed on the connecting plate, and the output end of the telescopic driving piece is connected with the filter plate.

[0024] By adopting the above technical scheme, the filter plate can accurately slide in the mold, thereby achieving the purpose of quickly replacing the filter element, and further improving production efficiency and operation convenience.

[0025] Optionally, the output end of the telescopic driving member is provided with a connecting head, and the connecting head is detachably connected with the filter plate.

[0026] By adopting the above technical scheme, the replacement of the filter plate is more convenient and fast, the downtime is reduced, and the production efficiency is improved. At the same time, this design is also convenient for maintenance and repair, and reduces the maintenance cost.

[0027] Optionally, the telescopic driving member is one of a pneumatic cylinder, a hydraulic cylinder and a pneumatic push rod.

[0028] By adopting the above technical scheme, not only the response speed and action accuracy of the system are improved, but also the reliability and stability of the equipment are enhanced, thereby ensuring the continuity and efficiency in the production process. In addition, the selection of these driving members can be flexibly adjusted according to the needs of specific application scenarios, further optimizing the system performance.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] Referring to Figure 1 and Figure 2 In the related art, a mold 10 is provided with a feeding port 11 and a discharging port 12 from top to bottom, a raw material feeding and discharging passage 13 is formed between the feeding port 11 and the discharging port 12, and mixed raw materials in a molten state pass through the raw material feeding and discharging passage 13.

[0042] The present application provides a screen changer structure for a stone paper production line, referring to Figure 3 and Figure 4 which comprises a filter plate 20, a filter element 30, and a filter plate pushing assembly 40. The filter element 30 is detachably installed in the filter plate 20, can be aligned with the raw material feeding and discharging passage 13 of the mold 10, and is in sliding connection with the mold 10. The filter plate pushing assembly 40 is used to drive the filter plate 20 to move, so that the filter plate 20 can slide into or out of the mold 10. This structure design makes the screen changing operation more convenient and efficient, reduces downtime, and improves production efficiency.

[0043] In an embodiment, only one filter element 30 is installed on a filter plate 20. When the filter element 30 needs to be maintained, the filter element 30 is moved out of the mold 10 by using the filter plate pushing assembly 40, and then the filter element 30 is maintained.

[0044] Referring to Figure 5 In another preferred embodiment, at least two filter elements 30 are arranged at intervals along the sliding direction of the filter plate 20. When one filter element 30 needs to be maintained, the other filter element 30 can be normally used, so that maintenance can be carried out without stopping.

[0045] Optionally, the filter 30 is composed of a filter screen, which is made of a multi-layer composite material including an outer layer of polyester fiber and an inner layer of stainless steel mesh, and can effectively filter impurities to ensure the purity of raw materials. The filter 30 can also be composed of a filter block, which is provided with a plurality of uniformly distributed filter holes for filtering impurities. The filter 30 and the filter plate 20 can be connected by clamping or other connection methods, allowing the filter 30 to be quickly disassembled and assembled on the filter plate 20.

[0046] Referring to Figure 4 In a preferred embodiment, the filter surface of the filter plate 20 and the filter surface of the filter 30 form a concave filter hole 31, and the filtered impurities can be placed in the concave filter hole 31, which is beneficial for subsequent unified collection of the filtered impurities. Further, the pore size of the concave filter hole 31 away from the filter 30 is smaller than the pore size close to the filter 30, forming a gradually changing pore size distribution, so that the impurities can be trapped in the concave filter hole 31, further enhancing the effect of concentrated treatment of impurities.

[0047] Referring to Figure 3 In a preferred embodiment, the filter plate 20 is provided with a heating assembly 50, which includes a heating rod. The heating rod is installed in the filter plate 20 along the sliding direction of the filter plate 20, and at least two heating rods are provided and located on both sides of the filter 30. The heating rod is made of an electric heating wire, which can quickly heat up to a set temperature to ensure the flowability of the material during the filtering process.

[0049] Optionally, the connecting rod 41 is made of high-strength carbon steel material, which has good tensile strength and toughness and can withstand a large pushing force. The connecting plate 42 is made of cast iron material, which has high rigidity and stability and can effectively transmit driving force. The telescopic drive 43 can be selected from a pneumatic cylinder, a hydraulic cylinder, or a pneumatic push rod, and the specific selection depends on the actual production environment and cost budget. For example, if there is a stable compressed air supply in the production site, a pneumatic cylinder can be selected as the telescopic drive 43 because of its simple structure, easy maintenance, and low cost.

[0050] In the embodiment, the connector 44 is an open-ended U-shaped connector 44, which is inserted into the upper and lower surfaces of the filter plate 20, and then locked by using a latch, and the subsequent disassembly and assembly are convenient; in another embodiment, the connector 44 is a quick connector, and the locking part of the quick connector is designed by using a spring buckle, which can be automatically locked when inserted, and only needs to be unlocked by pressing the button when pulled out.

[0051] The detachable connection between the connector 44 and the filter plate 20 is also conducive to the subsequent direct replacement of the filter plate 20, and at the same time, the filter plate 20 can be penetrated into the mold 10 along the sliding direction of the filter plate 20. This design can realize the bidirectional sliding of the filter plate 20, improve the flexibility, and facilitate the subsequent disassembly and assembly.

[0052] The implementation principle of the embodiment is that the embodiment provides a screen changer structure of a stone paper production line, which realizes the function of quickly replacing the filter element 30 by setting the detachable filter element 30 and the filter plate pushing assembly 40. The introduction of the heating assembly 50 solves the problem of poor material flowability in a low-temperature environment, and the selection of the telescopic driving element 43 and the design of the connector 44 improve the reliability and maintenance convenience of the system. The whole structure design is simple and compact, the operation is simple, the production efficiency can be significantly improved, the downtime can be reduced, the production cost can be reduced, and the market competitiveness of the enterprise can be improved.
