Description

Technical Field

[0001] The present application relates to the technical field of paper feeding mechanisms, and in particular to a paper feeding mechanism with an efficient waste paper cleaning function. Background Art

[0002] During the printing production process, printing paper needs to be fed out using a paper feeding mechanism. The outer surface of the printing paper is more or less covered with certain paper scraps, which will stick to the conveyor belt. During continuous work, the paper scraps will accumulate, which will easily affect the subsequent paper feeding work. The conveyor belt needs to be cleaned regularly.

[0003] In the prior art, paper scraps on the conveyor belt are generally handled by manual cleaning or vacuuming. The former requires shutdown during the cleaning process, and the actual efficiency is relatively low. The latter is due to the limited suction force, and large or heavy paper scraps cannot be effectively absorbed, resulting in incomplete cleaning of the adhered waste paper. Both methods have certain limitations. In this regard, the present application provides a paper feeding mechanism with an efficient waste paper cleaning function to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a paper feeding mechanism with an efficient waste paper cleaning function, comprising a main frame, a conveying assembly mounted on the inner side of the main frame, and a cleaning assembly for cleaning the conveying assembly mounted on the inner side of the main frame;

[0010] Furthermore, the conveying assembly includes two transmission shafts rotatably connected to the inner side of the main frame through bearings, a transmission roller fixed to the outer side of the transmission shaft, a transmission belt connected to the outer sides of the two transmission rollers, and a first servo motor fixedly installed on the front side of the main frame.

[0011] By adopting the above technical solution, printing paper can be transported.

[0012] Furthermore, the output shaft of the first servo motor passes through the front of the main frame and is fixedly connected to the front end of the right transmission shaft. The left and right sides and the top of the main frame are open, and the top of the transmission belt is located above the main frame.

[0014] Furthermore, the first limiting block is located between opposite sides of the two first positioning blocks, and the second positioning block is located between opposite sides of the two second limiting blocks.

[0015] By adopting the above technical solution, the first limiting block can be limited by the two first positioning blocks, and the second positioning block can be limited by the two second limiting blocks.

[0016] Furthermore, the connecting piece consists of a bolt and a nut, the end of the bolt passes through the first positioning block and the left side of the first limit block or between the two second limit blocks and the top of the second positioning block, and the nut is threadedly connected to the outside of the bolt.

[0017] By adopting the above technical solution, the connecting piece can connect and position the first limit block and the two first positioning blocks as well as the second positioning block and the two second limit blocks, thereby facilitating limiting the position of the collection box.

[0018] Furthermore, nylon bristles are bonded to the outer side of the cleaning roller, and the nylon bristles are in contact with the left side of the conveyor belt. The cleaning roller is located directly above the collection box.

[0030] See also Figures 1 to 4 The present application provides a technical solution: a paper feeding mechanism with an efficient waste paper cleaning function, comprising a main frame 1, a conveying assembly 200 installed on the inner side of the main frame 1, and a cleaning assembly 300 for cleaning the conveying assembly 200 installed on the inner side of the main frame 1; through the coordinated use of the conveying assembly 200 and the cleaning assembly 300 inside the main frame 1, continuous and effective waste paper cleaning can be performed during the paper feeding process, so that both large and small pieces of waste paper can be processed in a corresponding manner without affecting the continuous progress of the paper feeding work, and at the same time, it is convenient to process the collected waste paper, which greatly facilitates the operation of the staff and saves a certain amount of labor, so that the staff's labor can be used for more valuable work, thereby effectively improving the practicality of the paper feeding mechanism with an efficient waste paper cleaning function.

[0031] In this embodiment, the cleaning component 300 is a structure for cleaning and collecting paper scraps.

[0032] like Figure 1 、 Figure 3 and Figure 4As shown, the cleaning assembly 300 includes a cleaning rod 301 rotatably connected to the inner side of the main frame 1 through a bearing, a cleaning roller 302 fixedly mounted on the outer side of the cleaning rod 301, a second servo motor 303 fixedly mounted on the front side of the main frame 1, a collecting box 304 slidably connected to the inner bottom wall of the main frame 1, a dust collecting fan 305 fixedly mounted on the inner bottom wall of the main frame 1, an absorption pipe 306 fixedly mounted on the input end of the dust collecting fan 305, a trapezoidal air nozzle 307 fixedly mounted on the top of the absorption pipe 306, an exhaust pipe 308 fixedly mounted on the output end of the dust collecting fan 305, a fixing plate 309 fixed to the bottom of the main frame 1, a mounting frame 310 detachably connected to the bottom of the fixing plate 309, and a mounting plate 310 fixed to the mounting plate 310. A dust bag 311 is provided at the bottom of the frame 310; the cleaning assembly 300 also includes a support block 312 fixed to the inner bottom wall of the main frame 1 and fixedly connected to the outer side of the absorption tube 306, a connecting hole 313 is provided on the front of the main frame 1 and can be used for the collection box 304 to move, a first limit block 314 fixed to the front of the collection box 304, two first positioning blocks 315 fixed to the front of the main frame 1, two second limit blocks 316 fixed to the front of the collection box 304, a second positioning block 317 fixed to the front of the main frame 1, and two connecting pieces 318 passing between the two first positioning blocks 315 and the left side of the first limit block 314 and between the two second limit blocks 316 and the top of the second positioning block 317.

[0033] It should be noted that the first limit block 314 is located between the opposite sides of the two first positioning blocks 315, and the second positioning block 317 is located between the opposite sides of the two second limit blocks 316, so that the first limit block 314 can be limited by the two first positioning blocks 315, and the second positioning block 317 can be limited by the two second limit blocks 316. The connecting piece 318 is composed of a bolt and a nut. The end of the bolt passes through between the first positioning block 315 and the left side of the first limit block 314 or between the two second limit blocks 316 and the top of the second positioning block 317. The nut is threadedly connected to the outside of the bolt, so that the connecting piece 318 can connect and position the first limit block 314 and the two first positioning blocks 315 as well as the second positioning block 317 and the two second limit blocks 316, so as to facilitate limiting the position of the collection box 304.

[0034] In addition, the cleaning roller 302 is located directly above the collection box 304, so that the cleaned paper scraps can fall into the inside of the collection box 304 for collection. The output shaft of the second servo motor 303 passes through the front of the main frame 1 and is fixedly connected to the front end of the cleaning rod 301, so that the second servo motor 303 can drive the cleaning rod 301 to rotate.

[0035] At the same time, the end of the exhaust pipe 308 passes through the bottom of the main frame 1 and the top of the fixed plate 309 in sequence and extends to the interior of the dust bag 311. The mounting frame 310 is detachably connected to the bottom of the fixed plate 309 by screws, so that the paper scraps discharged from the exhaust pipe 308 can enter the interior of the dust bag 311 for collection. The dust bag 311 is easily disassembled and cleaned through the screw connection.

[0036] In this embodiment, the conveying assembly 200 is a structure for conveying printing paper.

[0037] like Figure 1 and Figure 2 As shown, the conveying assembly 200 includes two transmission shafts 201 rotatably connected to the inner side of the main frame 1 through bearings, a transmission roller 202 fixed to the outer side of the transmission shaft 201, a transmission belt 203 connected to the outer sides of the two transmission rollers 202, and a first servo motor 204 fixedly installed on the front side of the main frame 1.

[0038] It should be noted that the output shaft of the first servo motor 204 passes through the front of the main frame 1 and is fixedly connected to the front end of the right transmission shaft 201, so that the first servo motor 204 can drive the right transmission shaft 201 to rotate. The left and right sides and the top of the main frame 1 are all open, and the top of the conveyor belt 203 is located above the main frame 1, so that the printed paper can be transported on the top of the conveyor belt 203, wherein the opposite sides of two adjacent main frames 1 can abut each other, and the collection box 304 is located at the tail end of a section of the conveyor belt 203 for collection.

[0039] In addition, nylon bristles are bonded to the outside of the cleaning roller 302, and the nylon bristles are in contact with the left side of the conveyor belt 203, so that the cleaning roller 302 can clean the left side of the conveyor belt 203 through the nylon bristles. The trapezoidal air nozzle 307 is located at the bottom of the conveyor belt 203, so that the trapezoidal air nozzle 307 can absorb paper scraps at the bottom of the conveyor belt 203.

[0040] The working principle of the above embodiment is:

[0041] When feeding paper, the printed paper is placed on the conveyor belt 203, and the first servo motor 204 is started to drive the corresponding transmission shaft 201 to rotate, so that the two transmission rollers 202 rotate under the transmission action of the conveyor belt 203, thereby allowing the printed paper on the conveyor belt 203 to be transported. During the transportation process, the second servo motor 303 is started to drive the cleaning rod 301 to rotate, so that the cleaning roller 302 rotates and cleans the surface of the conveyor belt 203, allowing large pieces of heavy paper scraps to fall into the collection box 304 for collection. Start the dust collecting fan 305, and the small paper scraps that have not been swept off the bottom of the conveyor belt 203 can be absorbed through the absorption tube 306 and the trapezoidal air nozzle 307, so that they enter the dust bag 311 through the discharge pipe 308 for collection, thereby completing the paper scrap cleaning and collection work during the conveying process. When the collected paper scraps need to be taken out, remove the connecting piece 318 and move the collection box 304 out from the inner side of the connecting hole 313 to facilitate pouring out the paper scraps inside. By removing the mounting frame 310, the dust bag 311 can be disassembled for easy cleaning.

[0042] Compared with the prior art, the paper feeding mechanism with an efficient waste paper cleaning function can perform continuous and effective waste paper cleaning during the paper feeding process through the coordinated use of the conveying component 200 and the cleaning component 300 on the inner side of the main frame 1, so that both large and small pieces of waste paper can be treated in a corresponding manner without affecting the continuous progress of the paper feeding work. At the same time, it is also convenient for processing the collected waste paper, which greatly facilitates the operation of the staff and saves a certain amount of labor, so that the labor of the staff can be applied to more valuable work, thereby effectively improving the practicality of the paper feeding mechanism with an efficient waste paper cleaning function, and solving the problem that the existing paper feeding mechanism has large limitations in cleaning waste paper during the paper feeding process, resulting in insufficient cleaning of waste paper.

[0043] The electrical components appearing in this article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in this field. The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field. These are all existing publicly available power connection technologies and will not be described in detail in this article.
