Description
Technical Field
[0001] The utility model relates to the technical field of polarizer production, and in particular to a polarizer intermediate product production system. Background Art
[0002] Traditional polarizer production lines are usually set up in single-story workshops, with low space utilization, and different production processes are set up in different workshops. When semi-finished products are transported between different workshops, they need to be temporarily protected by PE film to prevent them from being scratched or damaged during transportation. After being transported to the next process, the PE film needs to be torn off before the next process can be carried out. Therefore, the attachment of PE film not only increases the transportation cost, but also greatly reduces the production efficiency.
[0003] With the upgrading of industries and the expansion of enterprise scale, the demand for space utilization and process optimization is increasing. Especially after moving to a new factory, due to the efficient use of land resources and changes in building structure, workshops need to be distributed on different floors. The traditional single-story workshop layout is no longer suitable for today's multi-story factories. And between floors, due to the short transfer distance, the method of applying PE film for temporary protection of semi-finished products, on the one hand, increases unnecessary production costs, and on the other hand, each process needs to install PE film attachment devices and PE film removal devices, which takes up too much factory space. Utility Model Content

[0012] A dust-proof conveying channel is set between each floor for the film material to be transported between different floors.

The dust-proof conveying channel is also provided with an air purification system to ensure that the film material is not polluted by dust in the external environment in the dust-proof conveying channel, thereby ensuring the cleanliness of the production environment.
[0013] The utility model solves the problem of low space utilization rate of single-story workshop by arranging different production processes in multi-story workshops; through scientific and reasonable space configuration, dust-proof conveying channels are opened between floors to realize the transfer of semi-finished products between different processes, and there is no need to temporarily protect the semi-finished products during the transfer process by attaching PE film on the semi-finished products, thereby maximizing the production efficiency inside the multi-story workshop and optimizing the process flow.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0037] In the production process of polarizer intermediate products, the traditional single-story workshop is divided into different production workshops according to different production processes. In order to better protect the semi-finished products during transportation to the next production workshop and avoid scratches on the semi-finished products during transportation, a layer of PE film needs to be laminated on the semi-finished products. However, this PE film cannot be reused, and when it reaches the next production line, it needs to be uncovered and torn off before the next process can be carried out.
[0038] In summary, the attachment of PE film, in addition to wasting materials and increasing production costs, also adds unnecessary processes and equipment, making the production process more complicated.
[0039] Therefore, our company has improved the intermediate product production process and provided a production line layout plan for a multi-floor factory, which enables the transfer of semi-finished products between different processes by opening dust-proof conveying channels between floors.
[0040] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.
[0041] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.
[0042] Embodiment 1:
[0043] A polarizer intermediate product production system, comprising: a PVA film stretching line 1 and an attaching device 9 arranged on the a layer of the production workshop, a TAC2 film saponification line 3, a laminating device 5 and a protective film device 8 arranged on the b layer, and a TAC1 film saponification line 2 arranged on the c layer;
[0044] A dust-proof conveying channel penetrating the floor partition is set between the a, b and c floors for the membrane materials to be transported between different floors;
[0045] The PVA film is processed by the PVA film stretching line 1 and then dried, and is compounded with the two layers of TAC film processed by the TAC2 film saponification line 3 and the TAC1 film saponification line 2 at the laminating device 5 to form a polarizer intermediate film; the polarizer intermediate film is conveyed to the attaching device 9 and compounded with the protective film of the protective film device 8 to form an intermediate product.
[0046] The utility model solves the problem of low space utilization rate of single-story workshop by arranging different production processes in multi-story workshops; through scientific and reasonable space configuration, dust-proof conveying channels are opened between floors to realize the transfer of semi-finished products between different processes, and there is no need to temporarily protect the semi-finished products during the transfer process by attaching PE film on the semi-finished products, thereby maximizing the production efficiency inside the multi-story workshop and optimizing the process flow.
[0047] The utility model adds a protective film device 8 on the b layer of the production workshop, and replaces the original PE film and intermediate film attachment by attaching the protective film to the intermediate film, thereby reducing the attachment and tearing steps of the PE film in the production process, making the process simpler, and no longer needing to waste PE film for transport protection of the intermediate film, because the protective film can replace this function, and the protective film does not need to be torn off in subsequent processes.
[0048] Embodiment 2:
[0049] The main difference between it and Example 1 is:
[0050] In this embodiment, if Figure 1 As shown, a polarizer intermediate product production system includes a PVA film stretching line 1, an attaching device 9, and a finished product winding device 10 arranged on the a layer of the production workshop, a TAC2 film saponification line 3, a laminating device 5, a second drying device 6, an inspection device 7, and a protective film device 8 arranged on the b layer, and a first drying device 4 and a TAC1 film saponification line 2 arranged on the c layer; during production, the PVA film is processed by the PVA film stretching line 1 and then extended to the first drying device 4 on the c layer for drying, and then the PVA film and the two layers of TAC film processed by the b layer TAC2 film saponification line 3 and the c layer TAC1 film saponification line 2 are compounded at the laminating device 5 to form a polarizer intermediate film. After the polarizer intermediate film is dried by the second drying device 6 and then inspected and qualified by the inspection device 7, the intermediate film is extended to the attaching device 9 on the a layer, and is compounded with the protective film of the protective film device 8, and then the finished product is rolled up by the finished product winding device 10.
[0051] The PVA film stretching line 1 comprises a washing treatment tank, a swelling treatment tank, a dyeing treatment tank, a cleaning treatment tank, a stretching treatment tank, a cleaning treatment tank, and a color-replenishing treatment tank, each of which is provided with a plurality of driving rollers for conveying the PVA film.
[0052] Dust-proof conveying channels are set between each floor for the membrane materials to be transported between different floors. The dust-proof conveying channel is set in a vertical or inclined pipeline style, and the inner wall of the pipeline is made of wear-resistant and smooth materials to reduce the dust generated by friction during the transportation of the membrane materials. Exits or entrances are set at both ends of the dust-proof conveying channel for the membrane materials to pass through. Multiple guide rollers are set in the dust-proof conveying channel to convey the membrane materials. The dust-proof conveying channel is also equipped with an air purification system to ensure that the membrane materials in the dust-proof conveying channel are not polluted by dust from the external environment, ensuring the cleanliness of the production environment.
[0053] like Figure 2As shown, the protective film device 8 includes a feed roller pair 81 and a conveying roller 82. The feed roller pair 81 includes a winding roller and a driven roller. The winding roller is wound with a protective film roll. The protective film is wound into a roll to form a protective film roll. The protective film roll and the outer cylindrical surface of the driven roller are in conflict with each other. This arrangement reduces the deformation probability of the protective film material and maintains the initial state of the film material. The protective film rolled out from the protective film roll is conveyed to the clamping roller 12 along the conveying path formed by the conveying roller 82.
[0054] The second drying device 6 is provided with a feed port and a discharge port, which are arranged opposite to each other, and a heating assembly 61 is arranged on one side of the second drying device 6 close to the feed port. A guide roller is arranged outside the feed port to convey the film material to the feed port. A plurality of conveying rollers 82 are arranged inside the second drying device 6. After the intermediate film material is conveyed by the conveying rollers 82, a zigzag reciprocating curved motion trajectory is formed inside the second drying device 6, which drives the air flow inside the second drying device 6, accelerates the air flow speed, accelerates the film material cooling speed, and accelerates the film material drying speed in the heating assembly 61. The film material comes out of the discharge port and enters the inspection device 7 for film material qualification inspection. The qualified film material comes out of the inspection device 7 and is conveyed to the clamping roller 12. In this embodiment, the curved motion trajectory is in the shape of "2". In other embodiments, the curved motion trajectory can also be other shapes, such as "S" shape, "N" shape, "bow" shape, etc.
[0055] The clamping roller 12 is arranged between the protective film device 8 and the inspection device 7. The clamping roller 12 includes a first roller and a second roller. The outer cylindrical surfaces of the first roller and the second roller are arranged to contact each other on the left and right. The protective film transported from the conveying roller 82 of the protective film device 8 and the intermediate film sent from the inspection device 7 are clamped by the clamping roller 12 on the left and right to be bonded and transported. After bonding, the film material is continuously transported by the conveying roller to the a-layer attaching device 9 for compounding.
[0056] In other embodiments, the outer cylindrical surfaces of the first roller and the second roller are arranged to contact each other up and down, and the film material passing through the clamping roller 12 is clamped up and down to be attached.
[0057] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "inside", "outside", "up", "down", "left", "right", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.
[0058] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
