Description

Technical Field

[0001] This utility model relates to the field of paper conveying technology, and specifically to a paper feeding mechanism that prevents moisture. Background Technology

[0002] A paper conveying mechanism is a device or system used to accurately, smoothly, and continuously transport paper from a starting position to a target position. It is commonly used in printing, packaging, office equipment and other fields. Through mechanical transmission, pneumatic adsorption and other methods, in conjunction with paper guiding and positioning components, it ensures that the paper moves along a predetermined path and speed to meet the needs of subsequent processing or use.

[0003] In existing technology, operators first arrange the paper to make it flat and undamaged, with the edges aligned, and then neatly stack it on the paper feeding tray in the paper feeding area. The paper feeding tray can provide stable support and does not hinder subsequent operations. Next is the critical separation, which is usually achieved by a paper separating knife to cut precisely or by suction nozzles to absorb negative pressure, ensuring single-sheet separation and preventing multiple sheets from being fed incorrectly or jammed. The separated paper is clamped by a conveyor roller (driven by a motor) or by a conveyor belt, and moves smoothly along a set path without deviation. Finally, it is processed by printing, cutting and other processes according to production needs.

[0004] However, in the actual operation of the existing paper feeding mechanism, the following three problems will occur: First, the paper may become damp due to the humid environment during the paper feeding process, affecting the paper quality; second, the paper may become wrinkled during the paper feeding process, affecting subsequent use; and third, the paper is easily contaminated by dust during the paper feeding process of the existing paper feeding mechanism. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a paper feeding mechanism that prevents moisture. By connecting and conveying hot air generated by an external heating device to the drying roller assembly, the drying roller assembly is rotated by the paper conveying structure to dry and heat the surface of the paper. The four drying roller assemblies prevent the paper from getting wet. The semi-enclosed structure on the upper part of the processing chamber can reduce dust on the surface of the processing chamber. The paper can be stretched by the adjustment component to reduce wrinkles.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A paper feeding mechanism for preventing moisture includes a processing chamber; it also includes a drying roller assembly and an adjusting assembly. The upper end of the processing chamber has a paper inlet / outlet slot for feeding and discharging paper. Four drying roller assemblies are provided on the processing chamber, two of which are mounted on two sets of mounting frames on the processing chamber, and the other two are set on adjusting assemblies at the front and rear ends of the processing chamber. Two limiting slide grooves are provided at the front and rear ends of the processing chamber. The adjusting assembly includes a cylinder mounted at the front and rear ends of the processing chamber, a connecting rod connected to the output shaft of the cylinder, a slide rod connected to the left and right ends of the connecting rod, and a connecting frame connected to the lower end of the slide rod. The drying roller assembly includes a bearing mounted on the connecting frame, a vent pipe rotatably mounted on the bearing, and a vent roller fixed to the vent pipe. The front and rear ends of the vent pipe are in a through state.

[0008] Preferably, the front and rear ends of the processing chamber are equipped with drying roller assemblies on corresponding mounting frames, and the outer wall of the bearing ring and the inner wall of the mounting frame are fixedly connected to each other.

[0009] Preferably, the front and rear ends of the processing chamber are provided with mounting slots, and connecting pipes are installed in the mounting slots. The ends of the two connecting pipes that are close to each other are connected to the drying box. The drying box is provided with air vents facing the direction of the paper.

[0010] Preferably, the paper is tensioned in a zigzag pattern on the outer wall of the four air-permeable rollers, and the front and rear ends of the air-permeable tube are connected to the bearings and screw rings. The screw rings are threaded with screw sleeves, which are conical in shape and used to install heat source interfaces.

[0011] Preferably, two limiting blocks are fixed to the front and rear ends of the processing chamber, and the sliding rod is slidably set within the limiting blocks.

[0012] Preferably, two magnetic strips are recessed at the front and rear ends of the processing chamber, next to the limiting slide groove, and a shielding mesh is provided in front of the magnetic strips.

[0013] Preferably, the upper end of the shielding mesh is fixed to the outer wall of the processing chamber, and multiple magnets are arranged on the shielding mesh near the magnetic strip. The magnets and the magnetic strip correspond to each other and attract each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By connecting and conveying the hot air generated by the external heating equipment to the drying roller assembly, the drying roller assembly is rotated by the paper conveying structure, and the surface of the paper is dried and heated. The four drying roller assemblies prevent the paper from getting wet, and the semi-enclosed structure on the upper part of the processing chamber can reduce dust on the surface of the processing chamber. The paper can be stretched by adjusting the assembly to reduce wrinkles.

[0016] 2. The heat source can dry the paper not only through the air pipe and air roller, but also through the drying box set in the processing chamber, or through the connecting pipe connected to the heat source, so that the paper can be dried over a large area through the drying box.

[0017] 3. When the connecting frame moves up and down by opening the cylinder to adjust the tension of the paper, the shielding mesh and the magnetic strip surface are used to prevent the limiting slide from being fully open, thus blocking some dust from entering. The shielding mesh on the connecting frame can also be set to two, distributed at the upper and lower ends of the connecting frame, and both connected to the processing chamber, thereby further improving the protective function. Through the above methods of reducing wrinkles, preventing moisture and dust, the number of defective paper packaging products is reduced, paper waste is reduced, and energy consumption is saved.

[0029] Please refer to Figures 1-6This utility model provides an embodiment of a paper feeding mechanism to prevent moisture, including a processing chamber 1; it also includes a drying roller assembly and an adjusting assembly. The upper end of the processing chamber 1 has an inlet / outlet slot 101 for feeding and discharging paper 2. Four drying roller assemblies are provided on the processing chamber 1, two of which are mounted on two sets of mounting brackets 104 on the processing chamber 1, and the remaining two are mounted on adjusting assemblies at the front and rear ends of the processing chamber 1. Two limiting grooves 102 are provided at the front and rear ends of the processing chamber 1. The adjusting assembly includes cylinders 404 mounted at the front and rear ends of the processing chamber 1, a connecting rod 402 connected to the output shaft of the cylinders 404, and connecting rods 402 to the left and right ends of the connecting rods 402. The slide bar 401 and the connecting frame 4 connected to the lower end of the slide bar 401 are included. The drying roller assembly includes a bearing 302 mounted on the connecting frame 4, a vent pipe 3 rotatably mounted on the bearing 302, and a vent roller 301 fixed on the vent pipe 3. The front and rear ends of the vent pipe 3 are in a through state. By connecting and conveying the hot air generated by the external heating equipment to the drying roller assembly, the drying roller assembly is subjected to the work of drying and heating the surface of the paper 2 after being transported and rotated by the transmission structure. The four drying roller assemblies prevent the paper from getting wet. The semi-enclosed structure on the upper part of the processing chamber 1 can reduce the dust on the surface of the processing chamber 1. The paper 2 can be stretched by adjusting the assembly to reduce wrinkles.

[0030] Please refer to Figures 1-6 In a preferred embodiment of this utility model, drying roller assemblies are jointly provided on the corresponding mounting brackets 104 at the front and rear ends of the processing chamber 1. The outer wall of the outer ring of the bearing 302 and the inner wall of the mounting bracket 104 are fixedly connected to each other. The front and rear ends of the processing chamber 1 are provided with mounting grooves 105. A connecting pipe 108 is provided in the mounting groove 105. The two connecting pipes 108 are connected to a drying box 106 through one end. The drying box 106 is provided with an air outlet 107 facing the paper 2. The heat source not only dries the paper 2 through the air pipe 3 and the air roller 301, but also through the drying box 106 provided in the processing chamber 1 and the heat source through the connecting pipe 108, so that the paper 2 can be dried over a large area through the drying box 106.

[0031] Please refer to Figure 4 and Figure 5In a preferred embodiment of this utility model, the paper 2 is tensioned in a zigzag pattern on the outer wall of the four air-permeable rollers 301. The front and rear ends of the air-permeable pipe 3 pass through the bearing 302 and are connected to a screw ring 303. A screw sleeve 304 is threaded onto the screw ring 303. The screw sleeve 304 is conical and used to install a heat source interface. Two limiting blocks 403 are fixedly connected to the front and rear ends of the processing chamber 1. The slide rod 401 is slidably disposed within the limiting blocks 403. Two magnetic strips 103 are recessed at the front and rear ends of the processing chamber 1 next to the limiting slide groove 102. A shielding mesh 5 is disposed in front of the magnetic strips 103. The upper end of the shielding mesh 5 is fixedly connected to the processing... On the outer wall of the chamber 1, multiple magnets 501 are arranged on the shielding mesh 5 near the magnetic strip 103. The magnets 501 and the magnetic strip 103 correspond to each other and attract each other. When the connecting frame 4 moves up and down by opening the cylinder 404 to adjust the tension of the paper 2, the shielding mesh 5 and the attraction of the magnets 501 to the surface of the magnetic strip 103 prevent the limiting slide 102 from being completely open, thus blocking some dust from entering. The shielding mesh 5 on the connecting frame 4 can also be set to two, distributed at the upper and lower ends of the connecting frame 4, and both are connected to the processing chamber 1, thereby further improving the protection function.

[0032] First, the heat source is connected to the heating and air-generating equipment. A perforated ball can be inserted into the screw sleeve 304 at the heat source input end of the pipe. Then, the screw sleeve 304 is threaded into the screw ring 303 so that the air pipe 3 does not affect the pipe inside the screw sleeve 304 during rotation. Next, the pipe connected to the heat source is connected to the connecting pipe 108. After the air pipe 3 is fed into the drying roller through the heat source, the paper 2 placed on its surface is dried and heated by the air roller 301.

[0033] During the drying process, the cylinder 404 can also be activated, causing the telescopic end of the cylinder 404 to move the connecting rod 402 up and down, thereby changing the position of the drying rollers on the two connecting frames 4 in the processing chamber 1, thus adjusting the tension of the paper 2 to cooperate with the drying rollers in preventing wrinkles.

[0034] The paper enters and exits through two paper inlet / outlet slots 101 on the processing chamber 1. To facilitate the adjustment of the tension of the limiting slide 102, a magnetic strip 103 and a foldable shielding mesh 5 are provided on it. When the connecting frame 4 moves up and down, the magnet 501 is always magnetically attracted to the magnetic strip 103, thereby reducing the exposed size of the limiting slide 102 and significantly reducing the problem of dust contamination on the paper 2.

[0035] Through the above steps, the hot air generated by the external heating equipment is connected and transported to the drying roller assembly. After the paper 2 is transported and rotated by the transmission structure, the drying roller assembly dries and heats the surface of the paper 2. The four drying roller assemblies prevent the paper from getting wet. The semi-enclosed structure on the upper part of the processing chamber 1 can reduce dust on the surface of the processing chamber 1. The paper 2 can be stretched by adjusting the assembly to reduce wrinkles.

[0036] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
