Description

Technical Field

[0001] This utility model relates to a polarizer conveying and feeding buffer device, belonging to the technical field of polarizer production equipment. Background Technology

[0002] Currently, the cut polarizing film needs to be conveyed to the receiving box via a conveyor belt. However, there is a gap between the end of the conveyor belt and the receiving box. During the receiving process, personnel need to be stationed on both sides of the receiving table to collect the material (cut polarizing film) and place it into the receiving box. This is labor-intensive. Furthermore, if there is residual adhesive on the end face of the material sheet, the adhesive will rub onto the surface of the material sheet when personnel pull it. This adhesive cannot be wiped off, resulting in defective material sheets and an increased loss rate. At the same time, since there are support corners at the four corners of the receiving box, and the height of the support corners is usually greater than the height of the receiving box, the material sheet is prone to collision and friction with the support corners when personnel pull it, causing scratches, abrasions, and wear on the material sheet, resulting in a high loss rate. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a polarizer conveying and feeding buffer device to reduce labor costs and reduce the loss rate.

[0004] The technical solution of this utility model is as follows: A polarizing film conveying and feeding buffer device includes an elastic buffer member disposed between the end of the conveyor belt and the receiving box. The elastic buffer member extends along the width direction of the conveyor belt. The elastic buffer member is a tubular structure formed by bending and joining the two edges of a sheet of plastic. The tubular elastic buffer member has elastic deformation capability. The top of the tubular elastic buffer member is higher than the support angle of the receiving box and lower than the end of the conveyor belt.

[0005] As a preferred embodiment of this invention, the cross-sectional shape of the tubular elastic buffer is fan-shaped, with the tip of the fan-shaped section pointing downwards to form the bottom of the tubular elastic buffer and the arc surface of the fan-shaped section pointing upwards to form the top of the tubular elastic buffer.

[0006] As a preferred embodiment of this invention, it also includes a triangular prism, wherein the two side edges of the sheet plastic are bent and fixedly connected to two of the sides of the triangular prism.

[0007] As a preferred embodiment of the present invention, it further includes a height adjustment component, which is used to adjust the height of the elastic buffer.

[0008] As a preferred embodiment of this utility model, the height adjustment assembly includes two symmetrically arranged adjustment plates, which are located on the outer sides of both ends of the elastic buffer. Each adjustment plate is provided with multiple adjustment holes, which are arranged at equal intervals along the vertical direction. The adjustment holes on the two adjustment plates correspond one-to-one. Threaded holes are formed on the end faces of the two ends of the triangular prism, and the two ends of the triangular prism are connected to the two adjustment plates by screws.

[0009] As a preferred embodiment of this invention, the bottom end of the adjusting plate is fixedly connected to the receiving table where the receiving box is located.

[0010] As a preferred embodiment of this invention, the distance between two adjacent adjustment holes on each adjustment plate is 5-7 mm.

[0011] As a preferred embodiment of this utility model, a rubber pad is provided between the end face of the triangular prism and the adjusting plate, the rubber pad is glued to the end face of the triangular prism, and the rubber pad is provided with a hole corresponding to the threaded hole.

[0012] The advantages of this utility model are: By setting up elastic buffers in the gap between the conveyor belt and the receiving box to create an elastic transition channel, the original manual collection process is replaced.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] The existing process for collecting cut polarizing films has some shortcomings, specifically including: High reliance on manual labor: After the cut polarizing film is conveyed to the end by the conveyor belt, there is a gap between the end of the conveyor belt and the receiving box. Staff members need to be arranged on the left and right sides of the receiving table where the receiving box is located to manually collect the material and guide it into the receiving box, which consumes a lot of labor.

[0017] High material loss rate: On the one hand, if there is residual adhesive on the end face of the material sheet, when the staff manually pulls the material, the residual adhesive is easy to rub onto the surface of the material sheet, and the adhesive cannot be removed by wiping, which directly leads to defective material sheets; on the other hand, the support corners set at the four corners of the receiving box are usually higher than the height of the receiving box body. During the manual pulling of the material, the material sheet is easy to collide and rub against the support corners, which will cause scratches, marks and wear problems, ultimately resulting in a high material loss rate.

[0018] Therefore, this embodiment is designed to solve the defects in the existing process of collecting cut polarizing films.

[0019] like Figure 1 and Figure 2 As shown, this embodiment is a polarizing film conveying and feeding buffer device, including an elastic buffer 3 disposed between the end of the conveyor belt 1 and the receiving box 2. The elastic buffer 3 extends along the width direction of the conveyor belt 1. The elastic buffer 3 is a tubular structure formed by bending and joining the two edges of a sheet of plastic. The tubular elastic buffer 3 has elastic deformation capability. The top of the tubular elastic buffer 3 is higher than the support angle 21 of the receiving box 2 and lower than the end of the conveyor belt 1.

[0020] In this embodiment, the cross-sectional shape of the tubular elastic buffer 3 is fan-shaped, with the tip of the fan pointing downwards forming the bottom of the tubular elastic buffer 3, and the arc surface of the fan pointing upwards forming the top of the tubular elastic buffer 3. Figure 3 As shown, the cross-sectional shape of the tubular elastic buffer 3 is designed as a fan shape, which can reduce the space occupied by the elastic buffer 3 between the end of the conveyor belt 1 and the receiving box 2, without the need for major modifications to the production line.

[0021] In order to maintain the fan-shaped cross-sectional shape of the tubular elastic buffer 3, such as Figure 3 and Figure 4 As shown, this embodiment also includes a triangular prism 4. The two sides of the sheet plastic constituting the elastic buffer 3 are bent and fixedly connected to two of the sides of the triangular prism 4. The edges of the sheet plastic and the sides of the triangular prism 4 are fixedly connected by adhesive. In practical applications, the edges of the sheet plastic and the sides of the triangular prism 4 can also be fixedly connected by multiple screws and washers.

[0022] like Figure 1 and2 As shown, this embodiment also includes a height adjustment component, which is used to adjust the height of the elastic buffer 3; thereby enabling the elastic buffer 3 to adapt to receiving boxes 2 of different heights; the height adjustment component includes two symmetrically arranged adjustment plates 5, which are located on the outer sides of both ends of the elastic buffer 3. Specifically, the adjustment plates 5 are vertically arranged, and the bottom end of the adjustment plate 5 is fixedly connected to the receiving table 6 where the receiving box 2 is located. Each adjustment plate 5 is provided with multiple adjustment holes 7, which are arranged at equal intervals along the vertical direction. The adjustment holes 7 on the two adjustment plates 5 correspond one-to-one. The two end faces of the triangular prism 4 are respectively formed with threaded holes 8. The two ends of the triangular prism 4 are respectively connected to the two adjustment plates 5 by screws. The screw rod passes through the adjustment hole 7 on the adjustment plate 5 and is threaded into the threaded hole 8 on the end face of the triangular prism 4.

[0023] like Figure 4 As shown, in this embodiment, a rubber pad 9 is provided between the end face of the triangular prism 4 and the adjusting plate 5. The rubber pad 9 is glued to the end face of the triangular prism 4 to fix the rubber pad 9. The rubber pad 9 is provided with a hole 10 corresponding to the threaded hole 8 for the screw to pass through. When the elastic buffer 3 is installed, the rubber pad 9 contacts the adjusting plate 5. The rubber pad 9 can increase the friction between the end face of the triangular prism 4 and the adjusting plate 5. After the screw is tightened, the triangular prism 4 is not easy to rotate freely.

[0024] In this embodiment, the interval between two adjacent adjustment holes 7 on each adjustment plate 5 is 5mm. In practical applications, the interval between two adjacent adjustment holes 7 on each adjustment plate 5 can also be designed to be 6mm or 7mm as required.

[0025] This embodiment establishes an elastic transition channel by setting an elastic buffer 3 in the gap between the conveyor belt 1 and the receiving box 2, so as to realize the automatic and smooth feeding of materials (cut polarizing film). The specific working process is as follows: The elastic buffer 3 is installed at a preset position between the end of the conveyor belt 1 and the receiving box 2, ensuring that the elastic buffer 3 extends along the width direction of the conveyor belt 1 and that its top height meets the requirement of "higher than the support angle 21 of the receiving box 2 and lower than the end of the conveyor belt 1", forming a smooth transition path from the conveyor belt 1 to the receiving box 2. After the cut polarizing film is normally conveyed to the end of the conveyor belt 1, it no longer relies on manual intervention, but naturally slides into the receiving box 2 through the elastic buffer 3 under its own inertia and gravity, avoiding the impact of direct fall. At the same time, The top of the elastic buffer 3 is higher than the support angle 21 of the receiving box 2. When the polarizer slides over the top of the elastic buffer 3, it will not come into contact with the support angle 21 of the receiving box 2. When the polarizer comes into contact with the elastic buffer 3, because the elastic buffer 3 is a tubular structure with elastic deformation capability, it can absorb the impact force of the polarizer sliding down through elastic deformation and slow down the movement speed of the polarizer. Subsequently, under the guidance of the elastic buffer 3 and its own gravity, the polarizer slowly slides along the top arc surface of the elastic buffer 3 and finally falls smoothly into the receiving box 2, completing the entire conveying and unloading process.

[0026] The principle of this embodiment is mainly: The elastic buffer 3 is a tubular structure formed by bending and joining the two edges of a sheet of plastic. Compared with the planar structure, the tubular structure has a certain elastic deformation capacity and impact absorption capacity, which can effectively buffer the impact force when the material slides down and prevent the material from being damaged by the impact. At the same time, the arc surface at the top of the tubular elastic buffer 3 can reduce the frictional resistance between the material and the elastic buffer 3, ensuring that the material can slide smoothly.

[0027] The top height of the elastic buffer 3 is strictly controlled to be lower than the end of the conveyor belt 1, so that the material can smoothly contact the elastic buffer 3 when it slides down from the end of the conveyor belt 1. The design of being higher than the support angle 21 of the receiving box 2 isolates the material from contact with the support angle 21 in space, eliminating the risk of scratches and wear caused by collision and friction between the material and the support angle 21, and reducing the loss rate.

[0028] The elastic buffer 3 extends along the width of the conveyor belt 1, and its coverage width matches the width of the conveyor belt 1. It can ensure that all materials that slide off the conveyor belt 1 (regardless of their position in the width direction of the conveyor belt) can be caught by the elastic buffer 3, avoiding material leakage or offset, and ensuring the comprehensiveness and stability of the falling material.

[0029] This invention creates an elastic transition channel by setting an elastic buffer in the gap between the conveyor belt and the receiving box, replacing the original manual collection process. It utilizes the material's own inertia, gravity, and the guiding effect of the elastic buffer to achieve automatic material delivery, reducing manpower input and avoiding material defects caused by residual adhesive during manual operation, thus balancing efficiency improvement and quality assurance.
