Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, in particular to a paper loading structure for printing. Background Art

[0002] In the prior art, the paper loading structure used for printing is a paper feeder, which feeds the papers into the printing press one by one for printing, especially in large printing presses, such as drum printing presses, etc. Large printing presses print large papers, and the paper loading structure separates the large papers so that they can gradually enter the printing press to achieve the purpose of printing. Therefore, the paper loading structure is particularly widely used in large printing presses.

[0003] There are various types of paper feeding structures in the prior art. For example, the Chinese utility model patent CN220596430U applied for by the applicant Ningbo Jinlan Paper Products Co., Ltd. discloses a printing paper feeding device, which includes a conveying mechanism, which includes a paper feeding assembly and a paper feeding assembly. The outer periphery of the paper feeding assembly and the paper feeding assembly is provided with a synchronous belt 1, and the paper feeding assembly includes a rotating shaft 2 and a rotating shaft 3. The rotating shaft 2 and the rotating shaft 3 are both connected to the upper part of the main device. One end of the rotating shaft 2 and the rotating shaft 3 is fixedly connected to a pulley 1, and the outer periphery of the two pulleys 1 is provided with a synchronous belt 3. A roller is fixed around the outer periphery of the rotating shaft 2, and a rubber pad is fixedly connected to the top of the main body. The roller is arranged on the top of the rubber pad. The rubber pad can separate the overlapping paper under the roller, and the uppermost paper is moved by rotating the roller. Although the device can realize the transmission of paper into the main body for printing, the above-mentioned device still has the following defects during use.

[0004] In the field of large-scale printing, the size of the paper is large, so the friction between the papers is large. Although the upper layer of paper can be conveyed into the printing machine by the rotation of the roller after the upper layer of paper is pressed against it, due to the large friction between the papers, the adjacent papers are likely to enter the printing machine together with the upper layer of paper. Therefore, the paper loading structure of the printing machine in the prior art is difficult to separate the papers one by one, and it is easy for multiple layers of paper to enter the printing machine simultaneously, causing certain inconveniences to printing. For this reason, we propose a printing paper loading structure to solve this problem. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] (1) In the paper loading structure of the present invention, the paper separator is assembled on the support frame on the fixed rod, and the paper separator is symmetrically arranged. The paper separator can absorb and lift the top layer of paper stack through the cooperation between the driver and the suction cup, so that the top layer of paper is separated from other papers and a cavity is generated, so that the top layer of paper can enter the printing press when the printing press feeds paper, thereby avoiding the problem of other papers entering the printing press along with the top layer of paper, resulting in reduced printing quality.

[0019] (2) The position of the paper separator in the present invention is adjustable. By adjusting the position between the paper separators, the distance between the paper separators is increased.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0037] like Figures 1 to 3 As shown, it is a structural schematic diagram of the paper loading structure for printing in this embodiment. The paper loading structure in this embodiment is used in a large printing machine to separate large papers so that the papers can enter the printing machine one by one for printing.

[0038] The paper loading structure in the present embodiment includes a supporting platform, and a paper separation mechanism 100 is arranged on the surface of the supporting platform. In the present embodiment, the paper separation mechanism 100 includes a fixed cylinder 101, and the fixed cylinder 101 is fixedly assembled on the surface of the supporting platform. A sliding rod 102 is slidably assembled in the fixed cylinder 101, and the top of the sliding rod 102 is connected to a fixed rod 103, and a supporting frame 104 is symmetrically arranged on the fixed rod 103, and a paper separator 106 is arranged on the supporting frame 104. In the present embodiment, the paper is placed on the supporting platform, and the paper separator 106 on the supporting frame 104 works to absorb and lift the top layer of paper, so as to separate the top layer of paper from other papers, so that the friction between the top layer of paper and other papers is reduced, and the top layer of paper can be transmitted into the printing press by using the paper feed roller in the printing press to avoid the problem that other papers follow the top layer of paper and enter the printing press synchronously. In addition, in the present embodiment, the sliding rod 102 is slidably assembled on the fixed cylinder 101, and the sliding rod 102 can slide relative to the fixed cylinder 101 to adjust the height of the fixed rod 103 and the supporting bracket 104, thereby facilitating the adjustment of the height of the paper separator 106, so as to facilitate the adjustment of the height of the paper separator 106 according to the stacking thickness of the printed paper. Moreover, in the present embodiment, a telescopic button is assembled on the sliding rod 102, and a matching hole is opened on the fixed cylinder 101. The mutual cooperation between the telescopic button and the matching hole can make the sliding rod 102 and the fixed cylinder 101 fixed to each other, so as to improve the stability of the fixed rod 103 and its paper separator 106 to facilitate the paper separation operation.

[0039] In this embodiment, the paper separator 106 includes a driver 106a and a suction cup 106b mounted on the driving end of the driver 106a. The driver 106a in this embodiment can drive the suction cup 106b to move downward until the suction cup 106b abuts against the surface of the topmost paper. In this embodiment, the suction cup 106b is also provided with an air pipe interface 106c, such as Figure 4 As shown, the air pipe interface 106c is connected to an external suction structure. When the suction cup 106b is in contact with the surface of the uppermost paper, the suction structure works to suck gas, so that the suction cup 106b adsorbs the uppermost paper. The driver 106a works in the reverse direction to lift the suction cup 106b. The suction cup 106b drives the uppermost paper upward to separate the uppermost paper from the adjacent paper, thereby reducing the friction between the uppermost paper and the adjacent paper. When the paper feed roller in the printing press works to convey the uppermost paper into the printing press, the suction mechanism works to inject gas into the suction cup 106b, so that the uppermost paper is separated from the suction cup 106b and enters the printing press for printing.

[0040] In this embodiment, the paper separator 106 can be used to lift the top layer of paper and separate it from the adjacent paper. Therefore, when the top layer of paper enters the printing press, other paper is prevented from entering the printing press synchronously, thereby improving the printing effect. In this embodiment, the paper separator 106 can be used to lift the top layer of paper so as to form a cavity between the top layer of paper and the adjacent paper. In order to further change the size of the cavity to reduce the friction between the paper, the support frame 104 in this embodiment is movably arranged on the fixed rod 103. The support frame 104 moves along the fixed rod 103 to drive the paper separator 106 to move, so that the distance between the paper separators 106 can be adjusted. When the distance between the paper separators 106 increases, the paper separator 106 lifts the top layer of paper so that the cavity between the top layer of paper and the adjacent paper increases, further reducing the friction between the paper and improving the paper separation effect.

[0041] like Figures 4 to 6 As shown, in this embodiment, the fixing rod 103 is provided with a fixing groove 103a along its length direction, and the supporting bracket 104 is sleeved on the fixing rod 103, and a fixing ear 104a is fixedly connected to the inner wall of the supporting bracket 104, and the fixing ear 104a is slidably assembled in the fixing groove 103a so that the supporting bracket 104 is slidably assembled on the fixing rod 103, and the supporting bracket 104 can only move along the length direction of the fixing rod 103 to avoid the problem of the supporting bracket 104 rotating relative to the fixing rod 103. In this embodiment, in order to further ensure the stability of the support bracket 104 relative to the fixed rod 103, threads are provided on the surfaces of both ends of the fixed rod 103, and the driving cylinders 105 are threadedly assembled on both ends of the fixed rod 103. The driving cylinder 105 is threadedly assembled with the fixed rod 103. The driving cylinder 105 can be rotated to move along the length direction of the fixed rod 103. The driving cylinder 105 abuts against the end of the support bracket 104. When the driving cylinder 105 moves, the support bracket 104 can be driven to move along the length direction of the fixed rod 103, thereby facilitating the adjustment of the support bracket 104. 04 and the position of the paper separator 106, so that the distance between the paper separator 106 is adjustable. In order to further improve the stability of the paper separator 106, a telescopic spring 107 is also sleeved on the fixed rod 103. The telescopic spring 107 is sleeved on the fixed rod 103 and both ends abut against the ends of the supporting brackets 104 on both sides thereof. The thrust of the telescopic spring 107 on the supporting bracket 104 and the thrust of the driving cylinder 105 on the supporting bracket 104 cooperate with each other to improve the stability of the supporting bracket 104, thereby making the stability of the paper separator 106 better, so as to facilitate the paper separation operation.

[0042] In this embodiment, the paper separator 106 lifts the top layer of paper so that the top layer of paper is separated from the paper below, thereby avoiding the problem that the paper below follows the top layer of paper into the printing machine synchronously. In addition, the distance between the paper separators 106 is adjustable, thereby adjusting the size of the cavity between the top layer of paper and the paper below after it is lifted, further reducing the friction between the top layer of paper and the paper below, further improving the paper separation effect, and improving the paper loading efficiency.

[0043] like Figure 1 as well as Figure 7 , Figure 8 As shown, in the paper loading structure of the present embodiment, the paper stopper 200 is symmetrically arranged on the surface of the supporting platform, and the paper stopper 200 blocks the paper, thereby ensuring the stability of the paper stack, so that the paper separation mechanism 100 can perform paper separation operation. In the present embodiment, the paper stopper 200 includes a paper stopper 201, and the end of the paper stopper 201 close to the paper loading structure is integrally formed with a stopper head 201d, and the paper stopper 201 is symmetrically arranged, and the stopper heads 201d are arranged opposite to each other. The paper stopper 201 and the stopper head 201d together constitute a space for holding the paper stack. The printed paper stack is placed on the surface of the supporting platform, and the paper stopper 201 is attached to the side of the paper stack, and the stopper head 201d is attached to the side of the end of the paper to limit the paper. In addition, the side of the paper stopper 201 close to the paper stack is further provided with a convex rib 201c. When the paper separator 106 separates the paper, the friction between the convex rib 201c and the paper further prevents the lower paper from being attached to the upper paper surface, thereby further improving the paper separation effect.

[0044] In this embodiment, in order to match the size of the paper, the paper blocking paper 201 in this embodiment is slidably assembled on the surface of the supporting platform. In this embodiment, the lower surface of the paper blocking paper 201 is fixedly connected with a sliding block 201b, and the surface of the supporting platform is provided with a slide groove 201a, and the sliding block 201b is slidably assembled in the slide groove 201a, so that the paper blocking paper 201 can slide on the surface of the supporting platform so that the paper blocking paper 201 is suitable for limiting the position of papers of different sizes. In this embodiment, fixing holes are provided on the paper blocking paper 201 and the supporting platform, and the paper blocking paper 201 can be fixed on the surface of the supporting platform by cooperating with the pin shaft and the fixing hole to limit the paper.

[0045] In this embodiment, after the paper stack is placed on the surface of the supporting platform, the paper blocking paper 201 slides and abuts against the side wall of the paper stack, and the stop head 201d abuts against the side wall of the end of the paper stack. The paper blocking paper 201 is fixed on the supporting platform through the cooperation of the pin shaft and the fixing hole, thereby realizing the limiting of the paper stack by the paper blocking paper 201. After the paper separation mechanism 100 works to separate the top layer of paper from the adjacent paper, the paper feed roller of the printing press works to transfer the top layer of paper into the printing press for printing. The paper loading structure in this embodiment can efficiently separate the paper, avoiding the problem of multiple layers of paper entering the printing press at the same time and causing printing inconvenience. In addition, the distance between the paper separators 106 in the paper separation mechanism 100 is adjustable, thereby further reducing the friction between the top layer of paper and the adjacent paper, further improving the paper separation effect.

[0046] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
