Description

Technical Field

[0001] This invention relates to the field of paper splicing technology, specifically a high-precision white paper splicer. Background Technology

[0002] Paper, also known as felt paper, is made from raw materials containing plant fibers through processes such as pulping, conditioning, papermaking, and processing. It can be used for writing, drawing, printing books and newspapers, packaging, etc. It is a sheet-like material that can be folded at will for writing. Paper is a medium for writing and printing, and can also be used for packaging, hygiene, and other purposes, such as printing paper, carbon paper, toilet paper, facial tissue, etc.

[0003] In the production process of white paper, multiple processing steps are usually required, and some paper often needs to be transported individually during the production process. Therefore, paper feeding and splicing machines for white paper have been designed to transport individual sheets of paper.

[0004] However, most existing white paper splicing machines require manual separation of the placed paper stacks. Furthermore, existing splicing devices typically place the paper feeding mechanism above the paper stack. During use, the paper feeding mechanism pushes the top of the paper stack to achieve the splicing effect. However, in actual use, it has been found that because the paper stack is not restrained, it is easy for the paper stack to shift and scatter during the paper feeding process, which greatly reduces the splicing accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision white paper connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-precision white paper connector, comprising a base plate and a pressure plate, wherein a through groove is formed in the middle of the base plate, a first support is provided on the front of the base plate, a second support is provided above the first support, and a support base is provided on the side of the base plate; a support plate is provided below the support base, and a connecting cylinder is provided below the support plate, through which a sliding rod passes, and a connecting plate and a connecting arm are respectively provided at both ends of the sliding rod; a second electric push rod is provided on the connecting plate, the end of the second electric push rod is fixed to the support plate, and a push roller frame is fixed to the end of the connecting arm. The frame is located inside the through groove, and multiple support rollers are installed inside the through groove. A push roller is installed inside the push roller frame. A telescopic rod is installed above the support base, a lifting plate is installed at the top of the telescopic rod, a pressure plate is installed below the lifting plate, and a spring is sleeved on the outside of the telescopic rod. The two ends of the spring are connected to the lifting plate and the support base, respectively. By placing the white paper stack on the base plate and pressing it down with the pressure plate, the white paper stack is restricted. Then, the sliding rod is pushed by the second electric push rod, so that the sliding rod drives the push roller frame to move through the connecting arm. The push roller of the push roller frame pushes the paper at the bottom of the white paper stack.

[0007] Preferably, the push roller is connected to the push roller frame via a one-way bearing. The one-way bearing can prevent the push roller from rotating when pushing the paper, and also prevent the push roller from pushing the paper when moving back, thus affecting normal use.

[0008] Preferably, a conveying roller is provided on the inner side of the first bracket, and a drive motor is provided on the side of the first bracket. The drive shaft of the drive motor is connected to the conveying roller. After the paper is pushed to the conveying roller, it is conveyed by the conveying roller.

[0009] Preferably, a movable roller frame is provided inside the second support, a pressure roller is provided inside the movable roller frame, and a first electric push rod is provided above the movable roller frame. The end of the first electric push rod is fixed on the second support. The movable roller frame is pushed downward by the first electric push rod, and then the pressure roller on the movable roller frame is used to press the paper, thereby improving the stability of the paper during feeding.

[0010] Preferably, a positioning rod is symmetrically provided above the movable roller frame on the side of the first electric push rod. The positioning rod passes through the first bracket and is connected to a positioning block. The positioning rod is provided to improve stability.

[0011] Preferably, the plurality of support rollers are arranged in a rectangular row.

[0012] Preferably, the connecting arm is L-shaped, and a reinforcing rib is provided on the inner side of the connecting arm to improve the supporting strength of the connecting arm.

[0013] Preferably, a rubber pad is provided below the pressure plate to increase friction.

[0014] Preferably, the connecting arm and the pressure plate are fixed to the sliding rod and the lifting plate respectively by bolts, thereby achieving detachable installation.

[0015] Preferably, a baffle is provided on the back of the base plate to limit the position of the white paper stack.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses a pressure plate to hold down the stack of white paper, restricting it. Then, a second electric push rod pushes a sliding rod, causing the sliding rod to move the push roller frame via a connecting arm. The push roller frame pushes the bottom paper of the stack of white paper, thereby improving the accuracy of paper feeding and splicing. The pressure roller presses the paper onto the conveyor roller, which then transports it. This effectively improves stability and the practicality of the device. Attached Figure Description

Inside, multiple support rollers 102 are provided on the inner side of the through groove 101, and push rollers 602 are provided on the inner side of the push roller frame 601; a telescopic rod 7 is provided above the support base 4, a lifting plate 701 is provided at the top of the telescopic rod 7, a pressure plate 702 is provided below the lifting plate 701, and a spring 703 is sleeved on the outer side of the telescopic rod 7, with the two ends of the spring 703 connected to the lifting plate 701 and the support base 4 respectively; by placing the white paper stack on the base plate 1, pressing the white paper stack with the pressure plate 702 to restrict it, and then using the second electric push rod 504 to push the sliding rod 502, so that the sliding rod 502 drives the push roller frame 601 to move through the connecting arm 6, and using the push roller 602 of the push roller frame 601 to push the paper at the bottom of the white paper stack.

[0027] Furthermore, the push roller 602 is connected to the push roller frame 601 via a one-way bearing. The one-way bearing can prevent the push roller 602 from rotating when pushing the paper, and at the same time prevent the push roller 602 from pushing the paper when moving back, thus affecting normal use.

[0028] Furthermore, a conveying roller 201 is provided on the inner side of the first bracket 2, and a drive motor 202 is provided on the side of the first bracket 2. The drive shaft of the drive motor 202 is connected to the conveying roller 201. After the paper is pushed to the conveying roller 201, it is conveyed by the conveying roller 201.

[0029] Furthermore, a movable roller frame 301 is provided on the inner side of the second support 3, and a pressure roller 302 is provided on the inner side of the movable roller frame 301. A first electric push rod 303 is provided above the movable roller frame 301. The end of the first electric push rod 303 is fixed on the second support 3. The movable roller frame 301 is pushed downward by the first electric push rod 303, and then the pressure roller 302 on the movable roller frame 301 is used to press the paper, thereby improving the stability of the paper during transport.

[0030] Furthermore, a positioning rod 304 is symmetrically provided above the movable roller frame 301 on the side of the first electric push rod 303. The positioning rod 304 passes through the first bracket 2 and is connected to a positioning block. The positioning rod 304 is provided to improve stability.

[0031] Furthermore, the plurality of support rollers 102 are arranged in a rectangular array.

[0032] Furthermore, the connecting arm 6 is L-shaped, and a reinforcing rib 603 is provided on the inner side of the connecting arm 6. The reinforcing rib 603 is used to improve the support strength of the connecting arm 6.

[0034] Furthermore, the connecting arm 6 and the pressure plate 702 are respectively fixed to the sliding rod 502 and the lifting plate 701 by bolts, thereby achieving detachable installation.

[0035] Furthermore, a baffle 103 is provided on the back of the base plate 1, which is used to limit the position of the white paper stack.

[0036] In summary, when using this invention, pulling the pressure plate 702 causes the lifting plate 701 to pull the spring 703 and the telescopic rod 7, causing the spring 703 and the telescopic rod 7 to extend. The stack of white paper is then placed on the support roller 102 on the base plate 1, simultaneously contacting the push roller 602. Then, releasing the pressure plate 702 causes the spring 703 to rebound, pulling the lifting plate 701 back. This causes the lifting plate 701 to drive the pressure plate 702 to press down on the stack of white paper, thus restricting it. Then, the second electric push rod 504 pushes the connecting plate 503, causing the connecting plate... 503 drives the sliding rod 502 to slide in the connecting cylinder 501, so that the sliding rod 502 drives the push roller frame 601 to move through the connecting arm 6. The push roller 602 of the push roller frame 601 pushes the paper at the bottom of the white paper stack. After the paper is pushed onto the conveying roller 201, the first electric push rod 303 is activated, so that the first electric push rod 303 pushes the movable roller frame 301 to move downward. The pressure roller 302 on the movable roller frame 301 presses down the paper. Then the drive motor 202 can be started to drive the conveying roller 201 to rotate for paper feeding and connection.

[0037] It is worth noting that the entire device is controlled by a master control button.
