Description

Technical Field

[0001] This utility model belongs to the field of polarizer processing technology, specifically relating to an edge material discharge device for large polarizer processing. Background Technology

[0002] A polarizer, also known as a light polarizer, is an important optical element widely used in various display technologies. The basic structure of a polarizer typically consists of multiple layers of polymer materials, the core of which is a polyvinyl alcohol (PVA) layer, which performs the polarization function. To protect the physical properties of the PVA layer, a layer of triacetate cellulose (TAC) film, which has high light transmittance, good water resistance, and a certain degree of mechanical strength, is usually laminated on both sides. The main function of a polarizer is to selectively filter light and control its propagation direction, thereby enabling image display.

[0003] In the processing of large polarizing films, excess edge material is cut off and transported to a designated waste bin. However, because the edge material of polarizing films is relatively thin, it is easy to stick to the conveyor belt during the discharge process and be synchronously guided into the equipment by the conveyor belt. This not only makes it impossible to effectively recycle the edge material, resulting in waste, but may also damage the machine. Therefore, it has significant limitations in practical use and has room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide an edge material discharge device for processing large polarizers, so as to solve the problem mentioned in the background art that the edge material of existing polarizers is easy to stick to the conveyor belt and is difficult to discharge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large polarizer edge material discharge device, comprising a symmetrically arranged body, a conveyor belt inside the body for discharging polarizer edge material; an inclined feeding plate is provided below the discharge direction of the conveyor belt, and a blowing assembly is provided between the feeding plate and the conveyor belt. The blowing assembly includes: a blowing element with an air outlet at the top and an air inlet at the bottom, wherein the top of the blowing element is inclined towards the discharge direction of the conveyor belt; and a supply element connected to the bottom of the blowing element, one end of which is embedded inside the body and the other end extends through to the outside of the body, thereby achieving installation of the supply element and the body, and also enabling communication with an external air supply device to discharge gas through the blowing element, thereby separating the edge material attached to the conveyor belt and enabling automatic discharge under gravity.

[0006] As a preferred technical solution of this utility model, the blowing component includes multiple duckbill nozzles, each duckbill nozzle having an end pipe symmetrically connected to both sides, and a connecting pipe sleeved on the outside of the end pipe. The connecting pipe is connected to the supply component, and the gas is transmitted to the connecting pipe and the end pipe through the supply component, and finally sprayed out through the duckbill nozzle. The top of the duckbill nozzle is inclined towards the discharge direction of the conveyor belt, thereby realizing the separation of the edge material from the conveyor belt.

[0007] As a preferred technical solution of this utility model, a rubber ring is bonded to the end of the end tube. The rubber ring abuts against the inner wall of the connecting tube. Through the tight connection between the rubber ring and the connecting tube, the two can be stably connected under the condition of no external force. At the same time, when subjected to external force to rotate, as long as the rotation force is greater than the squeezing force between the rubber ring and the connecting tube, the angle of the duckbill nozzle can be rotated, thereby making corresponding adjustments according to the discharge direction of the conveyor belt, and improving the speed and quality of separation of the edge material from the conveyor belt.

[0008] As a preferred technical solution of this utility model, the supply component includes multiple transmission tubes, each of which is movably sleeved on a single connecting tube. When it is necessary to adjust the horizontal position of the duckbill nozzle, the duckbill nozzle is directly moved, causing the connecting tube to move inside the transmission tube. This not only achieves the adjustment of the horizontal position but also ensures that the normal transmission of gas is not affected. The end of one of the outermost duckbill nozzles is inserted into one end of the machine body, while the other outermost duckbill nozzle extends through to the other end of the machine body. An air supply pipe is also connected to the end of the other duckbill nozzle, through which gas is transmitted. Therefore, the air supply pipe is connected to an external gas supply device.

[0009] As a preferred technical solution of this utility model, the end of the connecting pipe is provided with an annular groove, and a magnetic ring is installed in the annular groove. The magnetic ring is magnetically connected to the inner wall of the transmission pipe. Through the magnetic connection, the connecting pipe can be limited when it is not moving. When the connecting pipe at one end of the duckbill nozzle moves to the maximum distance, that is, when one end of the duckbill nozzle abuts against the transmission pipe, the connecting pipe at the other end of the duckbill nozzle is still inside the transmission pipe, thus avoiding separation.

[0010] As a preferred technical solution of this utility model, a partition ring is also provided in the middle of the inside of the transmission pipe. The partition ring can improve the strength of the transmission pipe itself. The inner diameter of the partition ring is equal to the inner diameter of the connecting pipe to ensure normal air passage.

[0011] As a preferred technical solution of this utility model, a support column is also provided on the outside of the transmission pipe. The bottom of the support column is installed on the feed plate. After the transmission pipe and the duckbill nozzle are installed, the position of the transmission pipe is fixed by the support column to prevent the transmission pipe in the middle position from moving when the duckbill nozzle is pushed. The support column can be fixed to the feed plate by spot welding or bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The designed blowing assembly can blow the edge material attached to the conveyor belt from bottom to top, thereby separating the edge material from the conveyor belt and ensuring normal subsequent feeding. It also prevents the edge material from moving into the equipment along with the conveyor belt. At the same time, the blowing assembly can adjust its position and angle according to actual usage requirements, greatly improving its overall flexibility and overcoming the shortcomings of the existing structure in use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a device for removing edge material during the processing of large polarizing films, comprising...

[0025] The machine body 100 is symmetrically arranged, and a conveyor belt 101 is provided inside the machine body 100 to discharge the edge material of the polarizer.

[0026] An inclined discharge plate 102 is provided below the discharge direction of the conveyor belt 101, and a blowing assembly is also provided between the discharge plate 102 and the conveyor belt 101. The blowing assembly includes:

[0027] The blowing component has an air outlet at the top and an air inlet at the bottom, with the top of the blowing component inclined toward the discharge direction of the conveyor belt 101.

[0028] The supply component is connected to the bottom of the blowing component. One end of the supply component is embedded inside the machine body 100, and the other end extends through the outside of the machine body 100, thereby realizing the installation of the supply component and the machine body 100. At the same time, it can also be connected to the external air supply equipment to discharge gas through the blowing component, thereby separating the edge material attached to the conveyor belt 101, so that the material can be automatically discharged under the action of gravity.

[0029] In this embodiment, preferably, the blowing component includes multiple duckbill nozzles 300. Each duckbill nozzle 300 has an end pipe 302 symmetrically connected to both sides. A connecting pipe 301 is sleeved on the outside of the end pipe 302. The connecting pipe 301 is connected to the supply component. The supply component transmits gas to the connecting pipe 301 and the end pipe 302, and finally sprays it out through the duckbill nozzle 300. The top of the duckbill nozzle 300 is inclined towards the discharge direction of the conveyor belt 101, thereby realizing the separation of the edge material from the conveyor belt 101.

[0030] In this embodiment, preferably, a rubber ring 303 is bonded to the end of the end tube 302. The rubber ring 303 abuts against the inner wall of the connecting tube 301. Through the tight connection between the rubber ring 303 and the connecting tube 301, the two can be stably connected when no external force is applied. At the same time, when subjected to external force, as long as the rotational force is greater than the squeezing force between the rubber ring 303 and the connecting tube 301, the duckbill nozzle 300-degree angle can be rotated. This allows for corresponding adjustments based on the discharge direction of the conveyor belt 101, thereby improving the speed and quality of separation between the edge material and the conveyor belt 101.

[0031] In this embodiment, preferably, the supply component includes multiple transmission pipes 200, each transmission pipe 200 being movably sleeved on a single connecting pipe 301. When the horizontal position of the duckbill nozzle 300 needs to be adjusted, the duckbill nozzle 300 is directly moved, causing the connecting pipe 301 to move inside the transmission pipe 200. This not only achieves horizontal position adjustment but also ensures that the normal transmission of gas is not affected. The end of one of the outermost duckbill nozzles 300 is inserted into one end of the body 100, while the other outermost duckbill nozzle 300 extends to the outside of the other end of the body 100. An air supply pipe 203 is also connected to the end of the other duckbill nozzle 300, through which gas is transmitted. Therefore, the air supply pipe 203 is connected to an external gas supply device.

[0032] In this embodiment, preferably, an annular groove is provided at the end of the connecting pipe 301, and a magnetic ring 304 is installed in the annular groove. The magnetic ring 304 is magnetically connected to the inner wall of the transmission pipe 200. Through the magnetic connection, the connecting pipe 301 can be limited when it is not moving. When the connecting pipe 301 at one end of the duckbill nozzle 300 moves to the maximum distance, that is, when one end of the duckbill nozzle 300 abuts against the transmission pipe 200, the connecting pipe 301 at the other end of the duckbill nozzle 300 is still inside the transmission pipe 200, thus avoiding separation.

[0033] In this embodiment, preferably, a partition ring 202 is also provided in the middle of the inside of the transmission pipe 200. The partition ring 202 can improve the strength of the transmission pipe 200 itself. The inner diameter of the partition ring 202 is equal to the inner diameter of the connecting pipe 301 to ensure normal air passage.

[0034] In this embodiment, preferably, a support column 201 is also provided on the outside of the transmission pipe 200. The bottom of the support column 201 is installed on the feed plate 102. After the transmission pipe 200 and the duckbill nozzle 300 are installed, the position of the transmission pipe 200 is fixed by the support column 201 to prevent the transmission pipe 200 in the middle position from moving when the duckbill nozzle 300 is pushed. The support column 201 can be fixed to the feed plate 102 by spot welding or bolts. The diameter of the support column 201 is 2mm, which does not affect the normal material discharge.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
