Description

TECHNICAL FIELD

[0001] The utility model relates to a feeding device, especially a feeding device of a polaroid edge grinding machine. BACKGROUND

[0002] With the increasing competition pressure of the polaroid industry and the decreasing market profit, cost reduction and efficiency increase have become the top priority of each polaroid manufacturer. In the edge grinding process of the polaroid, the conventional edge grinding steps are: feeding → edge knocking → equipment edge grinding → discharging → re-feeding. Since the polaroid is soft and easy to be damaged, and the polaroids are attached to each other, the polaroid edge grinding machine can only adopt the mode of multiple small polaroid feeding, because too much feeding at one time will make the polaroid products difficult to be knocked, thereby leading to poor grinding of the polaroid. The multiple small feeding mode makes the polaroid edge grinding machine have a long downtime for feeding, and the production efficiency is low. The existing feeding trolley has problems of being unable to reserve the polaroid grinding amount and being unable to be lifted, and is inconvenient to use. SUMMARY

[0003] In view of the above technical problems, the utility model discloses a feeding device of a polaroid edge grinding machine, which can complete the feeding preparation in advance during the grinding of the polaroid edge grinding machine.

[0004] Therefore, the technical scheme of the utility model is as follows:

[0005] A feeding device of a polaroid edge grinding machine comprises a workbench, two adjacent sides of the workbench are provided with vertical baffles, the inner side of the vertical baffle is provided with a micrometer at the lower part for controlling the gap between the object carrying base and the vertical baffle;

[0006] A bull's eye mounting plate is arranged below the workbench, the bull's eye mounting plate is connected with the workbench through a guide member; the bull's eye mounting plate is provided with a plurality of rotatable bull's eyes, the workbench is provided with a plurality of exposure holes for the bull's eyes to extend out, the bottom of the bull's eye mounting plate is connected with a lifting driving mechanism; the workbench is provided with a plurality of base fixing members for fixing the object carrying base. The length of the extension of the micrometer is used for controlling the grinding amount.

[0007] By adopting the technical scheme, the extension length of the micrometer is set, then the object carrying base is placed on the side of the workbench close to the vertical baffle, and the polaroid to be ground is placed on the object carrying base. The edge of the polaroid product can be knocked by using the limiting action of the vertical baffle. The feeding can be repeated multiple times, and the polaroid product can be repeatedly knocked until the required feeding amount is reached. The micrometer can control the distance between the object carrying base and the vertical baffle, and the distance corresponds to the grinding amount. The bull's eye mounting plate is connected with the workbench through the guide member, so that the position of the bull's eye mounting hole of the bull's eye mounting plate can be accurately aligned with the position of the bull's eye exposure hole of the workbench, and the bull's eye mounting plate does not tilt when being lifted.

[0008] After the edge grinding machine finishes grinding and unloading, align the worktable with the edge grinding machine table. Drive the bullseye mounting plate upward through the lifting drive mechanism, so that the bullseye extends out of the protrusion hole and contacts the base. Loosen the base fixing parts, and the base and polarizer on it can be moved freely under the rolling action of the bullseye. Push the base and polarizer on it into the edge grinding machine to start the next grinding cycle, which greatly saves the time of stopping the edge grinding machine for loading.

[0009] As a further improvement of this utility model, the bullseye mounting plate is provided with a boss, and the bullseye is provided on the boss.

[0010] As a further improvement of this utility model, the base fixing component includes a fixing frame, and a column is provided inside the fixing frame. The column includes an upright column body and a downwardly inclined arc-shaped portion. The column body is connected to the bottom of the fixing frame via a return spring, and the arc-shaped portion is rotatably connected to the side wall of the fixing frame. The arc-shaped portion is located above the bullseye mounting plate. In the natural state (i.e., without activating the lifting drive mechanism), the column body extends out of the surface of the fixing frame to limit the side of the load base and prevent displacement of the load base when aligning the polarizer. Pushing the arc-shaped portion upward causes it to rotate relative to the fixing frame, driving the column body to compress the spring and extend into the fixing frame. The fixing frame is fixedly connected to the worktable.

[0011] This technical solution involves placing the base on the worktable, with the column of the base holder extending out of the worktable and contacting the side of the base to limit its movement. As the bullseye mounting plate rises under the drive of the lifting mechanism, it contacts the arc-shaped part of the base holder, applying an upward force to the arc-shaped part and causing it to rotate relative to the holder. This causes the column to compress the spring downwards, retracting it into the holder and releasing the base. The bullseye mounting plate then contacts the worktable, and the bullseye extends out from the worktable and contacts the base. At this point, the base and its polarizer can be moved together to the edge grinding machine.

[0012] As a further improvement of this utility model, the position of the base fixing member corresponds to the position of the recessed part of the bullseye mounting plate. This technical solution can prevent the base fixing member from obstructing the bullseye when its curved portion rises, thus improving reliability.

[0013] As a further improvement of this utility model, in its natural state, the arc-shaped portion extends downwards from the bottom of the fixing frame.

[0014] As a further improvement of this utility model, the workbench is provided with a concave groove, and the fixing frame is provided with a straight groove, the straight groove being fixedly connected to the concave groove. Furthermore, the straight groove is fixed to the concave groove pre-reserved in the workbench by screws. In this technical solution, because the straight groove has a certain length, the base fixing component can move back and forth within a certain range, making installation and use convenient.

[0015] As a further improvement of this utility model, the bullseye mounting plate is provided with a reserved groove for the movement of the base fixing component, and the fixing frame is located within the reserved groove for the movement of the base fixing component. This technical solution prevents the arc-shaped part of the base fixing component from hitting the protrusion of the bullseye mounting plate and hindering its movement when it moves back and forth within the recessed groove reserved in the worktable.

[0016] As a further improvement of this utility model, at least two vertical baffles are provided on one side of the upper part of the workbench.

[0017] As a further improvement of this utility model, the vertical baffle is provided with a micrometer mounting hole, and the head of the micrometer is provided with a baffle for increasing the contact area between the micrometer head and the base.

[0018] As a further improvement of this utility model, the guiding component is a guide sleeve or a guide hole, and the bottom of the worktable is provided with a guide post. The guide post cooperates with the guide sleeve or guide hole so that the position of the bullseye can be accurately aligned with the position of the exposed hole of the worktable.

[0019] As a further improvement of this utility model, the lifting drive mechanism includes a piston rod and a hydraulic mechanism, and the bullseye mounting plate is provided with a piston rod fixing hole.

[0020] As a further improvement of this utility model, the hydraulic mechanism includes a hydraulic cylinder and a cylinder pump, wherein the cylinder pump is connected to the hydraulic cylinder and the hydraulic cylinder is connected to the piston rod.

[0021] As a further improvement of this utility model, the feeding device of the polarizer edge grinding machine includes a support frame, and the worktable is located on the support frame; the bottom of the support frame is equipped with casters. This technical solution facilitates movement.

[0022] As a further improvement of this utility model, the bracket is provided with a linear bearing for connecting to the bottom of the worktable, and a return spring is provided at the bottom of the linear bearing. This technical solution can control the baffle worktable from tilting during lifting and lowering. Simultaneously, when the hydraulic cylinder is depressurized and falls back, the return spring at the bottom of the linear bearing rebounds, giving the linear bearing a downward pulling force, thereby accelerating the falling speed of the worktable.

[0023] As a further improvement of this utility model, the bullseye mounting plate is provided with a plurality of bullseye mounting holes for mounting bullseyes.

[0024] As a further improvement of this utility model, the base is made of bakelite.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] The technical solution of this utility model includes a baffle and a micrometer on the table, which meets the requirements for pre-reserved grinding allowance and trimming when feeding polarizing film. At the same time, a base fixing component and a bullseye mounting plate are set up to solve the problem of matching the bullseye exposure and the extension and retraction of the base fixing component, so that polarizing film can be prepared outside the grinding machine. Furthermore, the bullseye mounting plate and the worktable can be raised and lowered to meet the feeding requirements of different table heights of the grinding machine. This device does not require the use of complicated gear transmission and motor, has a simple structure, low cost, wide environmental adaptability, and improves production efficiency.

[0048] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] like Figures 1-14As shown, a feeding device for a polarizing film edging machine includes a support 1, on which a worktable 2 is mounted. The bottom of the support 1 is equipped with casters 11 for easy movement. Vertical baffles 21 are located on adjacent sides of the worktable 2. A micrometer 22 is located on the lower inner side of the vertical baffles 21 to control the gap between the load base 6 and the vertical baffles 21. A bullseye mounting plate 3 is located below the worktable 2 and is connected to the worktable 2 via a guide member. The bullseye mounting plate 3 has a boss 31 with several rotatable bullseyes 32. The worktable 2 has several protrusion holes 24 for the bullseyes 32 to extend. The bottom of the bullseye mounting plate 3 is connected to a lifting drive mechanism 4. The worktable 2 has multiple base fixing members 5 for fixing the load base 6.

[0050] Specifically, the base fixing component 5 includes a fixing frame 51, within which a column 52 is provided. The column 52 includes an upright column 53 and a downwardly inclined arc-shaped portion 54. The column 53 is connected to the bottom of the fixing frame 51 via a spring 56. The portion of the arc-shaped portion 54 near the column 53 is rotatably connected to the side wall of the fixing frame 51 via a pivot 55. The arc-shaped portion 54 is located above the bullseye mounting plate 3. In its natural state, the column 53 extends beyond the surface of the fixing frame 51 to limit the side of the load base 6. Pushing the arc-shaped portion 54 upward causes it to rotate relative to the fixing frame 51, causing the column 53 to compress the spring 56 and extend into the fixing frame 51. The position of the base fixing component 5 corresponds to the position of the recessed portion of the bullseye mounting plate 3. In its natural state, the arc-shaped portion 54 extends downwardly from the bottom of the fixing frame 51. When the bullseye mounting plate 3 is not in contact with the curved portion 54, the head of the column 53 is extended under the action of the spring 56, allowing it to press against the base 6 and prevent displacement of the base 6 when aligning the polarizer 7. When the bullseye mounting plate 3 rises and begins to press against the curved portion 54, the column 53 will rotate and retract. Once the head of the column 53 is fully retracted, the base 6 can be moved. As the bullseye mounting plate 3 descends and gradually disengages from pressing against the curved portion 54, the spring 56 slowly returns to its extended state, allowing the head of the column 53 to slowly extend until it remains fully extended.

[0051] The vertical baffle 21 is provided with a micrometer mounting hole 27, and the head of the micrometer 22 is provided with a baffle 23. The micrometer 22 is installed into the micrometer mounting hole 27 of the vertical baffle 21, with the side with the baffle 23 facing inward and the side with the graduations facing outward. The micrometer 22 can be used to accurately control the reserved gap between the base 6 and the vertical baffle 21 (i.e., control the edge grinding allowance). Too much edge grinding allowance will result in poor grinding dimensions of the polarizer 7, while too little edge grinding allowance will cause the edge grinding machine to grind the base 6. The baffle can increase the contact area between the head of the micrometer 22 and the base 6, and together with the base fixing component 5, it can more firmly fix the base 6.

[0052] like Figure 9 As shown, the workbench 2 is provided with a concave groove 25, and the top of both sides of the concave groove 25 is provided with a plurality of screw holes 28. The fixing frame 51 is provided with a straight groove 57, and the straight groove 57 is fixed to the concave groove 25 by screws 58. And because the straight groove 57 has a certain length, the base fixing part 5 can move back and forth within a certain range.

[0053] The lifting drive mechanism 4 includes a piston rod 41 and a hydraulic mechanism. The hydraulic mechanism includes a hydraulic cylinder 42 and a cylinder pump 43. The cylinder pump 43 is connected to the hydraulic cylinder 42, and the hydraulic cylinder 42 is connected to the piston rod 41. The hydraulic cylinder 42 controls the lifting and lowering of the bullseye mounting plate 3. The cylinder pump 43 controls the lifting and lowering of the hydraulic cylinder 42.

[0054] The bullseye mounting plate 3 has several bullseye 32 mounting holes for mounting the bullseye 32. The bullseye mounting plate 3 also has piston rod 41 fixing holes 34 for connecting the piston rod 41 of the hydraulic cylinder 42, allowing the bullseye mounting plate 3 to rise and fall together with the hydraulic cylinder 42. The bullseye mounting plate 3 has a pre-reserved groove for the movement of the base fixing member 5. The fixing bracket 51 extends into the pre-reserved groove to prevent the arc-shaped part 54 of the base fixing member 5 from hitting the boss 31 of the bullseye mounting plate 3 when the base fixing member 5 moves back and forth in the pre-reserved concave groove 25 of the worktable 2, thus hindering its movement. The boss 31 of the bullseye mounting plate 3 controls the fit between the bullseye 32 and the base fixing member 5, ensuring that when the bullseye 32 protrudes from the worktable 2 at a specified height, the head of the column 53 of the base fixing member 5 is fully retracted. This allows the load base 6 to be released from its jamming state while smoothly sliding through the bullseye 32.

[0055] The guiding component is a guide hole 35 set on the bullseye mounting plate 3. The bottom of the workbench 2 is provided with a guide post 26. The guide post 26 cooperates with the guide hole 35 so that the position of the bullseye 32 on the bullseye mounting plate 3 can be accurately aligned with the position of the bullseye 32 exposed hole 24 on the workbench 2.

[0056] The support 1 is equipped with a linear bearing 12 for connecting to the bottom of the worktable 2, and a return spring 13 is provided at the bottom of the linear bearing 12. The bottom of the worktable 2 is equipped with a guide rod round head for connecting the linear bearing 12, which controls the baffle worktable 2 to prevent tilting during lifting and lowering. At the same time, when the hydraulic cylinder 42 is depressurized and falls back, the return spring 13 installed at the bottom of the linear bearing 12 rebounds, giving the linear bearing 12 a downward pulling force, thereby accelerating the falling speed of the baffle worktable 2.

[0057] Furthermore, the carrier base 6 is made of bakelite.

[0058] like Figures 11-14 As shown, this embodiment can be operated according to the following steps:

[0059] Step 1: Adjust the extension length of the micrometer 22 baffle according to the required edge grinding allowance, and at the same time loosen the pressure relief valve of the hydraulic cylinder pump 43 and lower the bullseye mounting plate 3.

[0060] Step 2: Place the base 6 on the workbench 2 and press it against the micrometer 22 baffles on both sides. At the same time, use the base fixing parts 5 to clamp the other two sides of the base 6 so that it cannot move.

[0061] Step 3: Place a certain number of polarizer 7 products on the carrier base 6, and align the edges of the polarizer 7 products. Repeat the loading and aligning process multiple times until the required quantity is reached.

[0062] Step 4: After the edge grinding machine finishes unloading the material, move the loading device of the prepared polarizing film edge grinding machine to connect with the edge grinding machine. Step on the hydraulic cylinder pump 43 to slowly lift the bullseye mounting plate 3 using the hydraulic cylinder 42. Eventually, the top of the bullseye 32 will be slightly higher than the table surface of the worktable 2, and the head of the column 53 of the base fixing part 5 will be completely retracted. Figure 12 As shown, if the foot pump 43 is pressed, the boss 31 of the bullseye mounting plate 3 will push against the worktable 2, thus raising the worktable 2 together. This can solve the problem of different table heights of different edge grinding machines. After the table height of the worktable 2 is determined and the edge grinding machine is connected, the base 6 and the polarizer 7 can be pushed onto the edge grinding machine table through the bullseye 32 for edge grinding.

[0063] Before using the technical solution of this embodiment, the average feeding time of a single stop of the edge grinding machine was 6 minutes. After using the technical solution of this embodiment, the average feeding time of a single stop of the edge grinding machine was reduced to 2 minutes, which improved production efficiency. The average uptime of a single edge grinding machine was increased by about 25%, and the daily output of the polarizer edge grinding machine was greatly increased, bringing considerable benefits to the enterprise.
