Detailed Description of the Preferred Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: Embodiment

[0028] A high-speed folding machine for quickly aligning paper includes support legs 1. A folding structure is installed at the top of the support legs 1. An adjustment structure is installed on the right side of the folding structure, and a paper output structure is arranged on the right side of the adjustment structure.

[0029] The adjustment structure includes an adjustment unit and an installation and measurement unit. The installation and measurement unit is arranged on the top of the adjustment unit. The adjustment unit includes a transfer rack 201. Transfer rollers 202 are installed on one side of the two transfer racks 201 close to each other. A guide plate 203 is arranged on the top of the transfer rollers 202. An adjustment block 204 is installed on the top of the left end of the guide plate 203. A bidirectional threaded rod 205 is connected inside the adjustment block 204. A knob 206 is installed on the front of the bidirectional threaded rod 205. The installation and measurement unit includes an installation block 207. A scale 208 is arranged on the top of the installation block 207. A sliding sleeve 209 is connected to the outer surface of the scale 208.

[0030] The inside of the installation block 207 is connected to the non-threaded parts at one end of the outer surface of the bidirectional threaded rod 205 close to the front and the back. The scale 208 is installed in the middle of the top surface of the back adjustment block 204. The bottom surface of the sliding sleeve 209 is fixedly connected to the middle of the top surface of the front adjustment block 204. The outer surface of the scale 208 is slidably connected to the inside of the sliding sleeve 209. The guide plate 203 is installed on the top of one side of the two transfer racks 201 close to each other.

[0031] The folding structure includes a workbench 101. A folding machine 102 is installed in the middle of the top surface of the workbench 101. An installation plate 103 is installed in the middle of the left side of the folding machine 102. A damping rod 104 is installed in the middle of the bottom surface of the installation plate 103. A pressing wheel 105 is installed at the bottom end of the damping rod 104. The bottom surface of the workbench 101 is fixedly connected to the top end of the support legs 1. The bottom surface of the transfer rack 201 is fixedly connected to the right end of the top surface of the workbench 101.

[0032] Through the setting of the adjustment structure and the folding structure, when the paper is conveyed by the transfer rollers 202, by rotating the knob 206 to drive the rotation of the bidirectional threaded rod 205, the two adjustment blocks 204 and the left ends of the two guide plates 203 are driven to approach each other, so as to adjust the distance between the guide plates 203 and the guiding angle. At the same time, the scale 208 and the sliding sleeve 209 are used for sliding, and the scale 208 is used to accurately measure the distance, so as to quickly guide and align the paper.

[0033] When the paper is conveyed by the conveying roller 202, the bidirectional threaded rod 205 is rotated by turning the knob 206. By means of the opposite threads provided at both ends of the outer surface of the bidirectional threaded rod 205 and the threaded connection between the outer surface of the bidirectional threaded rod 205 and the two adjusting blocks 204, the two adjusting blocks 204 are made to approach or move away from each other, so as to adjust the distance between the left ends of the guide plates 203, and thus adjust the guiding angle of the guide plates 203. By virtue of the sliding connection between the scale 208 and the sliding sleeve 209, the distance between the guide plates 203 can be accurately measured, and thus the distance through which the paper passes can be accurately measured, so as to ensure that the paper conveyed into the folding machine 102 for folding can be accurately and quickly aligned. After the paper is folded by the folding machine 102, by means of the stress of the damping rod 104, the bottom surface of the pressing wheel 105 is made to press and convey the paper, so as to ensure the stability of the paper discharging. Embodiment

[0034] On the basis of Embodiment 1, the paper discharging structure includes a storage box 301. A spring 302 is installed on the inner bottom surface of the storage box 301. A lifting plate 303 is installed at the top end of the spring 302. Sliders 304 are installed in the middle of the front and back of the lifting plate 303. The outer surface of the slider 304 is connected with a slide rail 305. A mounting frame 306 is installed in the middle of the top surface of the storage box 301. An electric push rod 307 is installed in the middle of the top surface of the mounting frame 306. A friction wheel 308 is installed at the output end of the electric push rod 307. The middle part of the left side of the storage box 301 abuts against the right end of the workbench 101. The slide rails 305 are fixedly installed in the middle of the front and back inner walls of the storage box 301. The outer surface of the slider 304 is slidably connected with the inner walls of the convex-shaped sliding grooves opened in the middle of the mutually approaching sides of the two slide rails 305. One end of the spring 302 away from the lifting plate 303 is fixedly connected with the bottom surface of the storage box 301.

[0035] Through the setting of the paper discharging structure, by means of the setting of the spring 302 and the lifting plate 303, and the sliding of the sliders 304 installed in the middle of the front and back of the lifting plate 303 inside the convex-shaped sliding grooves opened in the slide rails 305, the spring 302 stress drives the lifting plate 303 to rise with the weight of the paper, facilitating paper discharging.

[0036] By placing the paper into the interior of the storage box 301, the lifting plate 303 is pressed by the weight of the paper, thereby pressing the spring 302, causing the spring 302 to be pressed and contracted. As a result, the lifting plate 303 drives the paper to descend by sliding the slider 304 within the convex chute formed in the slide rail 305, and stores it inside the storage box 301. When the spring 302 is contracted to the shortest state, only the topmost paper is higher than the top surface of the storage box 301. Thus, the electric push rod 307 can be extended to drive the friction wheel 308 to abut against the paper, and the friction ring installed on the outer surface of the friction wheel 308 is used to friction the paper, thereby conveying the paper from the interior of the storage box 301 to the top of the conveyor roller 202 for conveyance. As the paper decreases and the weight lightens, the restoring deformation force of the spring 302 drives the lifting plate 303 to rise, thus facilitating paper output.
