Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard printing equipment, in particular to a paper conveying device with adjustable channels. Background Art

[0002] For some special cardboard materials, after being oiled by a high-speed oiling calender, there will be some burrs on the end surface, which is relatively rough and not smooth enough, and needs to be polished by a grinding wheel. Under the existing production conditions, different processing equipment is required for the oiling and polishing processes. One way is to set up the two devices independently, but this occupies a large area. And the sheet can only be oiled first, and then moved to the polishing equipment for polishing. It is necessary to go through multiple processes such as collection and transfer to complete a batch of printing, which not only has high labor costs, but also low production efficiency. The second is to directly connect the oiling and polishing equipment through a transmission belt. Although this does not require transfer, it is not conducive to the direct collection of smooth cardboard after oiling, and it will affect the efficiency of printing another type of cardboard. Therefore, the existing equipment cannot meet the production needs of frequent switching of printing of different cardboards. Utility Model Content

[0014] Figure 2 It is a structural schematic diagram of one embodiment of a paper conveying device with adjustable channel of the utility model. DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1-2 : A paper conveying device with an adjustable channel includes a base frame 1, the base frame 1 is provided with a polishing mechanism 2, the polishing mechanism 2 is arranged above the base frame 1, and the base frame 1 is also movably connected with a transmission mechanism 3, for example, by fixing a hydraulic rod 33 at the bottom of the base frame 1, connecting the rod part of the hydraulic rod 33 with the transmission mechanism 3, and the hydraulic rod can support the transmission mechanism 3. When the transmission mechanism 3 is pulled, it can move up and down. In this way, the base frame 1 is movably connected to the transmission mechanism 3 through the hydraulic rod 33. The transmission mechanism 3 is arranged on one side of the polishing mechanism 2, wherein the transmission mechanism 3 includes a bracket 31 and a conveyor belt 32, one end of the conveyor belt 32 is fixed on the bracket 31, and the positions of the conveyor belt 32 and the polishing mechanism 2 correspond, that is, the conveying port of the conveyor belt 32 is below the polishing mechanism 2, and the other end of the conveyor belt 32 is provided with a lifting device 4, and the lifting device 4 is connected to the base frame 1.

[0017] During installation, connect the discharging device of the high-speed oiling calender to the base frame 1, such as Figure 1As shown, the conveyor belt 11 of the discharge device is arranged below the polishing mechanism 2. The printed or oiled sheet material passes through the conveyor belt 11 of the discharge device. The polishing mechanism 2 is located between the conveyor belt 11 and the conveyor belt 32 on the other side. When the lifting device 4 and the polishing mechanism 2 cooperate, the lifting device 4 is lifted, driving one end of the transmission device to rise. Through the operation of their respective motors, the conveyor belt 32 and the polishing mechanism 2 work. The printed sheet material is driven by the conveyor belt 11 of the discharge device and extends into the gap between the polishing mechanism 2 and the conveyor belt 32, so that the polishing mechanism 2 polishes and grinds the sheet material. When the lifting device 4 shrinks downward, the conveyor belt 32 of the transmission device is arranged horizontally relative to the conveyor belt 11. After the paperboard is oiled, it can be directly transported and collected through the transmission mechanism 3 without passing through the polishing mechanism 2, and the switching is convenient. Therefore, the rough board material can be polished, and the moving distance of the rough board between the polishing and oiling mechanisms is saved, thereby saving the space occupied by the two mechanisms of polishing and printing. The entire device is simple and convenient to operate, greatly simplifies the entire process, and effectively improves the printing efficiency of switching different devices for different paperboards.

[0018] The lifting device 4 is a cylinder 41, which is vertically arranged and arranged at one end of the transmission mechanism 3 close to the polishing mechanism 2. This enables precise control of the lifting height of the conveyor belt 32. Specifically, one end of the cylinder 41 is fixed to the base frame 1, and the piston rod of the cylinder 41 is connected to one side of the transmission mechanism 3. The cylinder 41 can lift one side of the conveyor belt 32 by pushing the piston rod. By adjusting the extension degree of the cylinder 41, one end of the conveyor belt 32 can be lifted or lowered to a desired height to meet different cardboard printing requirements.

[0019] The polishing mechanism 2 includes a fixed roll 22 and a polishing wheel 21. The fixed roll 22 is fixed on the base frame 1, and the polishing wheel 21 is sleeved on the fixed roll 22. The polishing wheel 21 is cylindrical. When the motor of the polishing wheel 21 is started, the motor will drive the polishing wheel 21 to rotate around its axis. When the polishing wheel 21 rotates, the material to be polished is brought into contact with the polishing wheel 21, and a certain pressure is applied, so that the polishing plate rotates to polish the surface of the paper; thus, when the polishing wheel 21 contacts the rough cardboard, the surface of the polishing wheel 21 rubs against the surface of the cardboard, so that the surface of the rough cardboard is ground and polished. In order to improve the polishing effect, appropriate parameters such as the material of the polishing wheel 21, the polishing agent, and the rotation speed can be selected. For example, according to the desired grinding effect, an appropriate grinding paper particle size is selected, and a grinding paper board 23 or a frosting cloth can be sleeved on the outer surface of the polishing wheel 21. In addition, a polishing agent can be evenly and directly applied, as long as the polishing effect can be improved.

[0020] In order to prevent the conveyor belt 32 from getting too close to the polishing wheel 21, a blocking block 12 is provided on the side of the polishing wheel 21 close to the transmission mechanism 3, and the blocking block 12 is connected to the base frame 1. The blocking block 12 is arranged along the length direction of the polishing wheel 21, and the upper and lower positions of the blocking block 12 can be flexibly arranged according to actual needs, that is, as long as a certain gap is arranged between the blocking block 12 and the polishing wheel 21, the rotation of the polishing wheel 21 is not affected, and the height of the conveyor belt 32 is limited. In this way, when the conveyor belt 32 rises to a certain height, it will contact the blocking block 12, and will not directly contact the polishing wheel 21, thereby increasing safety. It can also help operators maintain an appropriate working position and distance, prevent their hands from approaching the polishing wheel 21, and reduce the risk of accidental contact.

[0021] The polishing mechanism 2 can be set as at least one group, that is, the corresponding polishing wheel 21 and the fixed roller 22 are each set to at least one, and the number of mechanisms can be set according to the polishing requirements in actual use. In some embodiments, when in use, the cylinder 41 is controlled to move so that the piston rod of the cylinder 41 pushes one end of the conveyor belt 32 to rise, that is, the end of the transmission mechanism 3 close to the base frame 1 rises, so that the transmission mechanism 3 gradually approaches the polishing mechanism 2. After the conveyor belt 32 approaches the predetermined position, the cylinder 41 is stopped, so that a certain angle is formed between the conveyor belt 32 and the conveyor belt 11 of the horizontal feeding device, and a gap is formed between the end of the conveyor belt 32 and the polishing mechanism 2 so that the cardboard can pass through. The motor of the polishing mechanism 2 is started, the polishing wheel 21 rotates, and the rough cardboard passes through the oil high-speed oiling calender, and then moves along the transmission mechanism 3 under the transmission of the conveyor belt 11, passes through the connection between the conveyor belt 11 and the conveyor belt 32, and is driven by the conveyor belt 32 to continue to move, so that the cardboard enters along the gap between the polishing wheel 21 and the conveyor belt 32, and is continuously polished by the polishing wheel 21 on the side facing the polishing wheel 21. After the polishing of a group of rough cardboards is completed, the feeding is stopped, the cylinder 41 is controlled to move, and the piston rod of the cylinder 41 is contracted, so that the conveyor belt 32 falls close to the base frame 1 and gradually moves away from the polishing mechanism 2 until the transmission mechanism 3 and the feeding device are kept relatively horizontal, and the feeding is continued. After a group of smooth cardboards are fed and oiled, they can be moved successively along the conveyor belt 11 and the conveyor belt 32 without passing through the polishing mechanism 2. Thus, the printed cardboards are directly collected. Therefore, the entire device has a simple structure, and the printing switching of different board materials is convenient and fast, and the working efficiency of the entire device is greatly improved.

[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
