Description

Technical Field

[0001] This utility model relates to the field of grey board paper processing technology, and in particular to a grey board paper single-sided printing machine. Background Technology

[0002] Grey board is a type of paperboard made from recycled waste paper. It is a type of packaging material and is widely used in packaging boxes, advertising boards, folders, photo frame backboards, bags, hardcover books, storage boxes, samples, linings, puzzles and other fields due to its good physical properties and environmental friendliness. In the process of grey board processing, it is printed on by a single-sided printing machine.

[0003] In order to ensure the printing quality of gray board paper, some existing single-sided printing machines usually set up two pressure plates to hold the gray board paper during the conveying process. However, the position of the pressure plates is fixed by bolts. When the position of the pressure plates needs to be adjusted according to the actual situation, the bolts need to be loosened and tightened separately, which is time-consuming and makes the adjustment of the position of the pressure plates inconvenient. Therefore, a single-sided printing machine for gray board paper is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a single-sided printing machine for grey board paper, which can solve the problem that some existing single-sided printing machines for grey board paper usually have two pressure plates to hold the grey board paper during the printing process. However, the position of the pressure plates is fixed by bolts. When the position of the pressure plates needs to be adjusted according to the actual situation, the bolts need to be loosened and tightened respectively, which is time-consuming and makes it inconvenient to adjust the position of the pressure plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-sided printing machine for grey board paper, including a conveyor belt, and further comprising:

[0006] A support plate is disposed on the upper surface of the conveyor belt;

[0010] Preferably, the limiting mechanism includes a motor disposed on the outer surface of the support plate, two reciprocating lead screws are rotatably connected to the inner surface of the support plate, the two reciprocating lead screws are fixedly connected and their screw grooves are arranged in opposite directions, the output end of the motor is fixedly connected to one of the reciprocating lead screws, a limiting plate is threadedly connected to the outer surface of the reciprocating lead screw, and both limiting plates are slidably connected to the support plate.

[0011] Preferably, the pitch of the reciprocating lead screw is 3mm.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application achieves the functions of limiting and holding grey board paper by setting up a limiting mechanism, a pressing mechanism, and a transmission mechanism. In use, the motor in the limiting mechanism reverses, causing the one-way bevel gear in the transmission mechanism to rotate, which in turn moves the pressure plate in the pressing mechanism up and down to the appropriate position. Then, the motor rotates forward, causing the limiting plate in the limiting mechanism and the pressure plate in the pressing mechanism, which have moved up and down to the appropriate position, to move horizontally to the appropriate position. During this process, when the motor rotates forward, the one-way bevel gear in the transmission mechanism is not rotating. This design not only simplifies the adjustment process of the pressure plate and the limiting plate and improves the operating efficiency, but also ensures the stability and printing quality of the grey board paper during the printing process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution:

[0027] A single-sided printing machine for grey board paper includes a conveyor belt 1, and also includes:

[0028] Support plate 2 is disposed on the upper surface of conveyor belt 1;

[0029] Printing module 3 is disposed on the inner surface of support plate 2;

[0030] Limiting mechanism 4 is disposed on the outer surface of support plate 2;

[0031] The pressing mechanism 5 is slidably disposed on the outer surface of the support plate 2, and the pressing mechanism 5 is slidably connected to the limiting mechanism 4.

[0032] Printing module 3 is a digital printing device capable of printing on greyboard paper, which is existing technology.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting mechanism 4 includes a motor 41 disposed on the outer surface of the support plate 2. Two reciprocating lead screws 42 are rotatably connected to the inner surface of the support plate 2. The two reciprocating lead screws 42 are fixedly connected and their screw grooves are arranged in opposite directions. The output end of the motor 41 is fixedly connected to one of the reciprocating lead screws 42. A limiting plate 43 is threadedly connected to the outer surface of the reciprocating lead screw 42. Both limiting plates 43 are slidably connected to the support plate 2.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, the pitch of the reciprocating lead screw 42 is 3mm, which can provide good transmission efficiency and stability.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pressing mechanism 5 includes a slide plate 51 that is slidably disposed on the outer surface of the support plate 2. Two pressure plates 52 are symmetrically slidably disposed on the outer surface of the slide plate 51. The pressure plates 52 are slidably connected to the limiting plate 43. Two reciprocating screws 53 are symmetrically threadedly connected to the inner surface of the slide plate 51. The two reciprocating screws 53 are rotatably connected to the support plate 2. The reciprocating screws 53 and the reciprocating screw 42 are connected by transmission mechanism 6.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission mechanism 6 includes a drive bevel gear 61 disposed on the outer surface of the reciprocating lead screw 42, and a one-way bevel gear 62 disposed on the outer surface of the drive bevel gear 61, which meshes with the drive bevel gear 61.

[0037] The unidirectional bevel gear 62 has a ratchet and pawl structure inside, which enables unidirectional rotation and is a current technology.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, the limiting plate 43, the sliding plate 51 and the pressure plate 52 are all made of polypropylene plastic, which has the characteristics of being lightweight, having high hardness and being corrosion resistant.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the outer surface of the limiting plate 43 near the printing module 3 and the lower surface of the pressure plate 52 are both provided with a lubricating coating, which can reduce the contact friction between the limiting plate 43 and the gray board paper, thereby facilitating the printing operation of the gray board paper.

[0040] Working principle: During use, motor 41 is started according to the actual situation. The output end of motor 41 reverses, driving reciprocating screw 42 to reverse. Then, the reciprocating screw 42 reverses, driving the drive bevel gear 61 to reverse, which in turn drives the one-way bevel gear 62 to rotate. Then, the rotation of the one-way bevel gear 62 drives the reciprocating screw 53 to rotate, which in turn drives the slide plate 51 to move up and down. Then, the up and down movement of the slide plate 51 drives the pressure plate 52 to move up and down to the appropriate position. Afterward, the output end of motor 41 rotates forward, driving the reciprocating screw 42 to rotate forward, which in turn drives the drive bevel gear 61 to rotate forward. When the one-way bevel gear 62 is not rotating, the forward rotation of the reciprocating screw 42 will drive the limiting plate 43 to move back and forth, which in turn will drive the pressure plate 52, which moves up and down to the appropriate position, to move back and forth. After the limiting plate 43 and the pressure plate 52, which moves up and down to the appropriate position, have moved back and forth to the appropriate position, the motor 41 can be stopped. Then, the gray board paper is placed on the conveyor belt 1 for conveying, and then the gray board paper is printed by the printing module 3. During this process, the limiting plate 43, which moves to the appropriate position, limits the gray board paper, and the pressure plate 52, which moves to the appropriate position, presses the gray board paper.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
