Description

TECHNICAL FIELD

[0001] The utility model relates to face paper feeding device. BACKGROUND

[0002] In the production of leather shell, paper box and the like, face paper is needed for production. Generally, the face paper is stacked on a lifting platform for feeding, and then a paper feeding device (such as a flying paper feeder) arranged at the top is used for conveying and outputting. The lifting platform is lowered to stack the face paper on it for feeding. For example, in the production of a frame box, the frame box is enclosed in a horizontal mold. In addition, a separate piece of face paper can be pasted on the upper side of the outer wall of the frame box in the horizontal state, and the frame box is formed and produced in cooperation (after the face paper is pasted, an oven lamp (such as an infrared lamp or a heating lamp) can be arranged on the front of the horizontal mold at a position corresponding to the upper edge of the box bottom to make the glue of the face paper work quickly, so as to avoid the problem of unstable folding and bottom connecting due to insufficient time, and to ensure efficiency). The size of the paper box body is relatively large, so the height of the corresponding mold is also relatively high, and the height of the face paper feeding and outputting is also relatively high, which is relatively matched and helps to improve the production efficiency. The face paper needs to be stacked and fed after the lifting platform is lowered, which is low in efficiency and causes the subsequent equipment to wait for the face paper. In addition, in the case of high face paper feeding and outputting, the height (the number of face papers) of the stacked face paper is also relatively high to increase the feeding capacity, which also causes time occupation and affects the production efficiency. SUMMARY

[0003] In view of the technical problems in the background art, the utility model aims to provide a face paper feeding device which reduces waiting time and is more efficient.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a face paper feeding device, comprising a lifting feeding frame, and a lifting driving component connected to the lifting feeding frame, characterized in that: the lifting feeding frame comprises left and right separate supports, and a telescopic lifting plate component for holding a stacked loading tray is arranged on each of the left and right separate supports, and the left and right separate supports leave a containing space between them for the stacked loading tray to be placed, and a feeding table is arranged below the lifting feeding frame, and the feeding table has a supporting part for placing the stacked loading tray.

[0005] The above technical solutions can be further optimized or supplemented as follows.

[0006] For example, the telescopic lifting plate component comprises a swing telescopic hook, the telescopic hook body is hinged to the support, and the telescopic lifting plate component has an extended lifting plate state and a retracted state.

[0007] It is further stated that the telescopic hook swings from top to bottom towards the containing space inside the support to be in the extended lifting plate state, and the telescopic hook swings back to be in the retracted state and exits the containing space.

[0008] In addition, a limiting structure is provided between the telescopic hook and the bracket to allow it to swing out into place.

[0009] For example, the limiting structure uses a blocking and limiting part set on the bracket.

[0010] Further optimization involves extending the telescopic hook by its own weight or by a spring swing.

[0011] The upper part of the lifting feeding rack is equipped with a paper feeding device.

[0012] It can also be optimized by setting an inverted vertical paper guide bar above the lifting feeding rack, and providing a clearance hole on the stacked material tray for the vertical paper guide bar to pass through; the left and right positions of the vertical paper guide bar can be adjusted.

[0013] The front of the lifting feeding rack is also equipped with a front guard; the front guard includes left and right corner gauges, and the left and right positions of the corner gauges are adjustable; the left or right side of the material preparation table is also equipped with a vertical paper gauge; the vertical paper gauge is set on the paper gauge rack, and the left and right positions of the paper gauge rack are adjustable.

[0014] In addition, at least two stacking trays are provided. The stacking trays have a stacking surface for stacking the face paper. The stacking trays placed on the support of the preparation table also have mating parts on the left and right sides for the telescopic lifting mechanism to support and lift them.

[0015] The beneficial effects of this utility model are that, during the normal feeding process of the lifting feeding frame, the lower part of the feeding device can be prepared. When the paper on the lifting feeding frame is used up, it can be lowered directly to lift the stacked material tray of paper on the preparation platform and raise it to feed normally. This can reduce the subsequent downtime and waiting time and is relatively more efficient. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Referring to the accompanying drawings, in this embodiment, the paper feeding device includes a lifting feeding frame 1, which is connected to a lifting drive component 2. The lifting feeding frame 1 includes left and right supports 10 (i.e., a left support 10 and a right support 10). For example, the lifting drive component 2 includes a drive motor (such as a servo motor) that drives the supports 10 to rise and fall through a chain and sprocket transmission structure 20, a belt and pulley transmission structure, or a lead screw and nut structure. The supports 10 can be configured on a vertical guide rail for stable lifting and falling. The technology of the lifting drive component 2 driving the lifting feeding frame 1 to rise and fall is relatively mature and will not be described in detail.

[0034] In this embodiment, the left and right supports 10 are each equipped with a telescopic lifting plate component 11. The telescopic lifting plate component 11 is used to support the stacked material trays 4. The left and right sides of the stacked material trays 4 can be supported and lifted by the telescopic lifting plate component 11 (which can extend and retract), so that the stacked material trays 4 can be lifted and lowered by the supports 10. The left and right supports 10 have a space between them to accommodate the stacked material trays 4, which can be located between the left and right supports 10.

[0035] The lifting feeding frame 1 is equipped with a material preparation platform 3 below it. The material preparation platform 3 has a support part 30, which is used to place the stacked material trays 4. The support part 30 supports and places the stacked material trays 4 for material preparation. During material preparation, the stacked material trays 4 are placed on the material preparation platform 3, and then paper materials are stacked on the stacked material trays 4. The paper can be stacked to the required height as needed. Generally, material preparation can begin when the paper on the stacked material trays 4 on the lifting feeding frame 1 (its support 10) is almost used up when it has risen to the highest position. At this time, there is sufficient space below the lifting feeding frame 1 for stacking material preparation. After the material preparation is completed, wait for the paper sheets on the stacked trays 4 on the lifting feeder 1 (its support 10) to be used up. At this time, the lifting feeder 1 can be lowered. During the descent of the lifting feeder 1, the stacked trays 4 on the lifting feeder 1 (its support 10) will also be lowered and land on top of the stacked prepared paper sheets below (they can be manually removed and placed on the preparation platform 3 for use when preparing materials again). The lifting feeder 1 can continue to descend, and the telescopic lifting plate component 11 can be retracted so that after descending through the stacked trays 4 located on the preparation platform 3, the telescopic lifting plate component 11 will extend again, and then the lifting feeder 1 can rise. The telescopic lifting plate component 11 will lift the stacked trays 4 with the replenished paper sheets from the preparation platform 3 to raise them for normal material supply. The preparation platform 3 can then place the stacked trays 4 back in to wait for the next material preparation.

[0036] During the normal feeding process of the lifting feeding frame 1, the paper feeding device can prepare materials below. When the paper on the lifting feeding frame 1 is used up, it can be lowered directly to support the stacked material tray 4 of the paper on the preparation platform 3 and lift it up to feed materials normally. This can reduce the subsequent downtime and waiting time and is relatively more efficient.

[0037] Based on the above embodiments, the following optimizations or further explanations can be made.

[0038] For example, the telescopic lifting plate component 11 can be driven by a power source (such as a motor or cylinder).

[0039] For example, the telescopic lifting plate component 11 includes a swing-type telescopic hook 12. The telescopic hook 12 is hinged to the bracket 10. The telescopic hook 12 can swing back and forth around the hinge axis 13 to form a telescopic structure. By swinging, the telescopic lifting plate component 11 has an extended lifting plate state and a retracted state.

[0040] For example, the telescopic hook 12 swings downwards towards the inner accommodating space of the bracket 10, reaching the extended, raised state; the telescopic hook 12 swings back and retracts out of the accommodating space, reaching the retracted state. Furthermore, a limiting structure 14 is provided between the telescopic hook 12 and the bracket 10 to ensure proper extension and stability, allowing the limiting structure 14 to restrain the telescopic hook 12 when it reaches its extended position. For example, the limiting structure 14 may be a blocking and limiting part 15 (such as a limiting step, limiting block, limiting groove, or limiting surface) provided on the bracket 10. Further optimization involves extending the telescopic hook 12 by its own weight (e.g., the telescopic hook 12 is biased to allow it to swing in the extension direction) or by the spring 16 (e.g., a torsion spring), requiring no additional power operation. This makes it more practical, stable, and efficient. When swinging back, no power operation is required. The stacked material tray 4 is used to push open the telescopic hook 12 to overcome its own weight and the effect of the spring 16, resulting in more stable operation. For example, the spring 16 can be set between the telescopic hook 12 and the bracket 10, and a hook seat 101 can be set on the bracket 10. The telescopic hook 12, the blocking and limiting part 15, the hinge shaft 13, and the spring 16 are all set on the hook seat 101 to form a combined structure for easy overall installation.

[0041] The upper part of the lifting feeder 1 is equipped with a paper feeding device (such as a feeder or a robotic arm with an air nozzle).

[0042] In addition, to ensure the relatively accurate positioning of the face paper, an inverted vertical paper guide rod 5 can be installed above the lifting feeder 1. The stacking tray 4 has clearance holes 40 (which can be elongated horizontal holes) through which the vertical paper guide rod 5 passes. During the upward movement of the lifting feeder 1, the inverted vertical paper guide rod 5 helps to constrain the position of the face paper, preventing it from shifting outwards. The vertical paper guide rod 5 can be adjusted left and right to limit the position on both sides of the face paper, and its position can be adjusted to meet different face paper specifications. For example, the vertical paper guide rod 5 (inverted) can be installed on an adjusting seat above the lifting feeder 1, with the adjusting seat positioned on a horizontal track, and the adjusting seat can be adjusted left and right by a screw and nut structure.

[0043] Of course, a front stop 6 can also be configured on the front side of the lifting feeder 1 to limit the position of the face paper at the front. The front stop 6 includes left and right corner gauges, which can limit the position of the face paper at the left and right corners of the front side. In addition, the left and right positions of the corner gauges can be adjusted, such as by setting them on the horizontal guide rod and adjusting their left and right positions by a screw and nut mechanism to meet the requirements of different face paper specifications. In addition, the left or right side of the preparation table 3 is also equipped with a vertical paper gauge 7. The vertical paper gauge 7 is set on the paper gauge frame 70 (a vertical paper gauge 7 that can be removed by inserting holes on the paper gauge frame 70) and the left and right positions of the paper gauge frame 70 can be adjusted. The vertical paper gauge 7 can also be used to limit the position during the preparation process. It is more practical and can meet the requirements of different face paper specifications by adjusting the left and right positions. There are many ways to adjust the left and right positions, such as setting the paper gauge frame 70 on the horizontal rail and adjusting it by a screw and nut mechanism. The stacking tray 4 can be provided with a side opening slot to avoid the vertical paper gauge 7, so as to put the stacking tray 4 into and take it away. Positioning pins 31 can also be set on the material preparation table 3, and positioning holes can be set on the stacked material trays 4 so that the relative position of the stacked material trays 4 is accurate when placed on the material preparation table 3.

[0044] Among them, at least two stacking material trays 4 are configured (which can be used alternately, one can be placed on the lifting feeding frame 1 and the other can be placed on the preparation platform 3). The stacking material trays 4 have a stacking plane for stacking face paper. The stacking material trays 4 placed on the support part 30 of the preparation platform 3 also have a cooperating part on the left and right sides for the telescopic lifting plate part 11 to support and lift them, so that the telescopic lifting plate part 11 can smoothly support and lift the stacking material trays 4 after it descends.
