Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a paper feeding device. Background Art

[0002] When using thin sheet papers such as Tyvek paper, the conventional method is to place a stack of papers on a platform and then manually pick them one by one for subsequent use. However, manual picking is not only inefficient but also prone to the problem of picking multiple papers at once, and it is easy to scatter the whole stack of papers, which affects subsequent work.

[0003] There are also automated devices developed on the market that suck papers one by one through suction nozzles for subsequent use. However, due to the lack of an effective feeding method for the whole stack of papers, the above problems existing in manual paper picking still exist, and the cost investment of the whole set of automated equipment is relatively large, which is not conducive to small-scale production. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a paper feeding device, including a bottom plate. L-shaped angle plates are arranged at the four corners of the bottom plate. Between two L-shaped angle plates on the same side, an L-shaped pressing plate located above the L-shaped angle plates is installed through a rotating shaft to press the four sides of the whole stack of papers from the upper side.

[0005] A sliding sleeve is arranged in the middle of the bottom plate. A guide post is slidably arranged in the sliding sleeve. The top of the guide post is horizontally provided with a jacking plate, and the jacking plate is located between the four L-shaped angle plates. A spring is arranged between the jacking plate and the sliding sleeve.

[0006] Further: The L-shaped angle plates are made of metal, and magnets are arranged on the L-shaped pressing plates. When the L-shaped pressing plates press the papers, the magnets are used to suck the L-shaped angle plates to prevent the L-shaped pressing plates from automatically opening and being unable to press the papers when an external suction nozzle sucks the papers.

[0007] Further: Locking blocks are further arranged at the tops of the L-shaped angle plates. Pins corresponding to the upper side of the papers are installed on the locking blocks through locking screws to prevent the papers below from being taken out when an external suction nozzle sucks the upper papers.

[0008] Further: Limiting buckles are further arranged on the lower side surface of the jacking plate. Elastic locking buckles corresponding to the limiting buckles are arranged on the side part of the bottom plate to limit the jacking plate in the compressed state of the spring to facilitate the placement of the whole stack of papers.

[0009] Among them: Two limiting buckles are symmetrically arranged on the lower side surface of the jacking plate, and elastic locking buckles corresponding to the two limiting buckles are respectively arranged on the side parts of the bottom plate to achieve symmetrical and balanced locking.

[0010] Wherein, two same-direction limiting buckles are arranged on the lower side of the jacking plate, and elastic locking buckles corresponding to the two limiting buckles respectively are arranged on the side of the bottom plate, and the elastic ropes of the two elastic locking buckles are linked, so as to realize the simultaneous separation or locking with the two limiting buckles through the linkage mode by pressing or resetting one of the elastic locking buckles.

[0011] Compared with the prior art, the utility model is different from the film and paper feeding mechanisms on the market. By acting on the paper with a pressing plate to prevent material carrying during material taking and using the elasticity of a spring to realize the jacking of the paper, the structure is more delicate, effectively solves the feeding problem of papers such as Tyvek paper, reduces the equipment cost and space, and has the advantages of stable design and stable feeding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0016] Embodiment 1:

[0017] Please refer to Figure 1-2 , this Embodiment 1 provides a paper feeding device, including a bottom plate 10, L-shaped angle plates 11 made of metal are arranged at the four corners of the bottom plate 10, and an L-shaped pressing plate 22 located above the L-shaped angle plates 11 is installed between two L-shaped angle plates 11 on the same side through a rotating shaft 21 to press the four sides of the whole stack of papers from the upper side; a sliding sleeve 41 is arranged in the middle of the bottom plate 10, a guide post 42 is slidably arranged in the sliding sleeve 41, the top of the guide post 42 is horizontally provided with a jacking plate 43 and the jacking plate 43 is located between the four L-shaped angle plates 11, and a spring 44 is arranged between the jacking plate 43 and the sliding sleeve 41.

[0018] Wherein: The L-shaped angle plate 11 is made of metal, and a magnet 23 is provided on the L-shaped pressing plate 22. When the L-shaped pressing plate 22 presses the paper, the magnet 23 is used to suck the L-shaped angle plate 11, so as to prevent the L-shaped pressing plate 22 from automatically opening when the external suction nozzle sucks the paper, resulting in the inability to press the paper 50.

[0019] Wherein: A locking block 31 is further provided at the top of the L-shaped angle plate 11, and a pin 33 corresponding to the upper side of the paper is installed on the locking block 31 through a locking screw 32, so as to prevent the lower paper 50 from being carried out when the external suction nozzle sucks the upper paper.

[0020] Wherein: Two limiting buckles 45 are symmetrically arranged on the lower side surface of the lifting plate 43, and elastic locking buckles 46 corresponding to the two limiting buckles 45 are respectively arranged on the side parts of the bottom plate 10, so as to achieve symmetric balance locking and limit the lifting plate 43 in the compressed state of the spring 44, which is convenient for placing the whole stack of papers 50.

[0021] Working principle of Embodiment 1:

[0022] First, when placing the paper 50, the L-shaped pressing plates 22 on the four sides are opened outwards;

[0023] Then, the lifting plate 43 is pressed down to compress the spring 44 to reset the lifting plate 43, and the limiting buckles 45 are buckled by the elastic locking buckles 46 on both sides to prevent the lifting plate 43 from rising and affecting the placement of the paper 50;

[0024] Then, the whole stack of papers 50 is placed on the lifting plate 43. After the papers 50 are placed, the L-shaped pressing plates 22 are reset and the L-shaped angle plates 11 are tightly sucked by the magnets 23;

[0025] Finally, by pressing both hands and simultaneously releasing the limiting buckles 45 on both sides, at this time the spring 44 resets and the lifting plate 43 rises, so as to press the whole stack of papers on the lifting plate 43 in cooperation with the L-shaped pressing plates 22. At this time, the topmost paper 50 can be sucked one by one through the external suction mechanism; during this process, the setting of the pin 33 can prevent the lower paper 50 from being carried out when the external suction nozzle sucks the upper paper.

[0026] Embodiment 2:

[0027] The difference between this Embodiment 2 and Embodiment 1 is that two same-direction limiting buckles 45 are arranged on the lower side surface of the lifting plate 43, and elastic locking buckles 46 corresponding to the two limiting buckles 45 are respectively arranged on the side parts of the bottom plate 10, and the elastic ropes of the two elastic locking buckles 46 are linked, so as to realize that by pressing or resetting one elastic locking buckle 46, the simultaneous separation or locking with the two limiting buckles 45 can be realized through the linkage mode. This kind of linkage mode can realize unlocking the buckle by pressing with one hand.

[0028] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
