Technical Field
[0001] This utility model relates to the field of cardboard box manufacturing equipment, and more specifically, to a paper forming plate folding device for a bottom gluing machine. Background Technology
[0002] Cardboard boxes are made from trees, a renewable resource that is biodegradable and recyclable, naturally giving them an eco-friendly label. Bottom-gluing machines primarily fold and glue die-cut cardboard boxes into finished boxes. Current market bottom-gluing machines have simple mechanical structures and are easy to operate and adjust. They can automatically feed paper and apply glue to the overlapping tongues of semi-finished cardboard boxes. Most cardboard boxes are currently made from a single sheet glued together. After the bottom-gluing machine, the bottom usually still needs to be folded and glued manually. The production speed depends on the operator's skill level, and the machine requires a large workforce; typically three to six people are needed for a single row of paper receiving and gluing, which is very inefficient. Therefore, a device needs to be designed to allow the bottom-gluing machine to automatically fold the paper into a board.
[0003] This invention can automatically fold paper forming plates and reduce the need for automatic paper forming plates to recover after folding, as well as the function of step-by-step folding. Summary of the Invention
[0004] The present invention aims to solve the technical problems mentioned in the background art and provide a paper forming plate folding device for a paste-making machine, which achieves automatic folding of the paper forming plate and reduces the automatic recovery of the folded paper forming plate and the effect of step-by-step folding.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a paper forming plate folding device for a paper pasting machine, comprising: a conveying device, wherein a vertical guide plate is fixedly installed on the upper and lower sides of the front center of the conveying device, a lower folding plate is fixedly installed at the bottom of the front end of the conveying device, and an upper folding plate is fixedly installed at the top of the front end of the conveying device; a horizontal guide plate is fixedly installed at the top of the lower folding plate and the bottom of the upper folding plate.
[0006] The lower folding plate includes: a first horizontal plate, a first long curved plate, a first inclined plate, a first short curved plate, and a vertical plate; the first horizontal plate is fixedly installed at the bottom of the front end of the transmission device, the first long curved plate is fixedly connected to the right end of the first horizontal plate, the first inclined plate is fixedly connected to the right end of the first long curved plate, the first short curved plate is fixedly connected to the right end of the first inclined plate, and the vertical plate is fixedly connected to the right end of the first short curved plate.
[0007] The upper folding plate includes: a second horizontal plate, a second long curved plate, a second inclined plate, and a second short curved plate; the second horizontal plate is fixedly installed at the top end of the front end of the transmission device; the second long curved plate is fixedly connected to the right end of the second horizontal plate, and the second inclined plate is fixedly connected to the right end of the second long curved plate; the second short curved plate is fixedly connected to the right end of the second inclined plate.
[0008] A further preferred embodiment: a first guide rod is fixedly connected to the left end of the lower folding plate; a second guide rod is fixedly connected to the left end of the upper folding plate.
[0009] A further preferred embodiment: the left ends of the first guide rod and the second guide rod are provided with guide ramps.
[0010] A further preferred embodiment: the first long curved plate is 40 centimeters longer than the second long curved plate.
[0011] A further preferred embodiment: a plurality of first support rods are fixedly connected to the bottom end of the lower folding plate; a plurality of second support rods are fixedly connected to the top end of the upper folding plate.
[0012] A further preferred embodiment: an inclined guide plate is fixedly connected to the left end of the vertical guide plate.
[0013] A further preferred embodiment: the vertical guide plate and the horizontal guide plate are provided with support devices. Beneficial effects
[0014] 1. By setting up a multi-segment folding plate, the automatic recovery of the paper forming plate after folding is reduced. The paper forming plate is folded three times, through a horizontal plate, a long curved plate, and a short curved plate, to complete the entire folding process. If it is folded only once, the paper forming plate will have a large rebound. Multiple folds can greatly reduce the rebound of the paper forming plate and ensure product quality.
[0015] 2. By setting horizontal plates of different lengths, the step-by-step folding effect is achieved; the first long curved plate is longer than the second long curved plate, so that the second paper forming plate enters the first long curved plate later, thus making the second paper forming plate complete the folding more slowly. This enables the device to achieve step-by-step folding, so that the device can fold more paper forming plates, such as when the second paper forming plate is longer and needs to be covered on the first paper forming plate.
[0016] 3. In summary, this paper forming plate folding device for the paste-making machine, by setting up a structure with multiple folding plates and horizontal plates of different lengths, can automatically fold the paper forming plate and reduce the automatic recovery of the paper forming plate after folding and the step-by-step folding function.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0025] Please see Figure 1-6 In this embodiment of the present invention, a paper forming plate folding device for a bottom pasting machine includes: a conveying device 1, a vertical guide plate 2 fixedly installed on the upper and lower sides of the front center of the conveying device 1, a lower folding plate 4 fixedly installed at the bottom of the front end of the conveying device 1, and an upper folding plate 5 fixedly installed at the top of the front end of the conveying device 1; a horizontal guide plate 3 fixedly installed at the top of the lower folding plate 4 and the bottom of the upper folding plate 5.
[0026] The lower folding plate 4 includes: a first horizontal plate 402, a first long curved plate 404, a first inclined plate 405, a first short curved plate 406, and a vertical plate 407; the first horizontal plate 402 is fixedly installed at the bottom of the front end of the transmission device 1, the first long curved plate 404 is fixedly connected to the right end of the first horizontal plate 402, the first inclined plate 405 is fixedly connected to the right end of the first long curved plate 404, the first short curved plate 406 is fixedly connected to the right end of the first inclined plate 405, and the vertical plate 407 is fixedly connected to the right end of the first short curved plate 406.
[0027] The upper folding plate 5 includes: a second horizontal plate 502, a second long curved plate 504, a second inclined plate 505, and a second short curved plate 506; the second horizontal plate 502 is fixedly installed at the top end of the front end of the transmission device 1; the second long curved plate 504 is fixedly connected to the right end of the second horizontal plate 502, the second inclined plate 505 is fixedly connected to the right end of the second long curved plate 504, and the second short curved plate 506 is fixedly connected to the right end of the second inclined plate 505.
[0028] In use, the upper and lower paper forming plates fold in a similar manner, differing only in the folding time. Taking the lower paper forming plate as an example, the upper end of the lower paper forming plate is clamped on the conveyor 1 and moved to the right by the conveyor 1. When the upper end of the lower paper forming plate contacts the vertical guide plate 2, the paper forming plate is clamped between the conveyor 1 and the vertical guide plate 2. As the paper forming plate continues to move to the right, the lower end of the paper forming plate contacts the first guide rod 401 of the lower folding plate 4. At this time, the paper forming plate will gradually rise. Then, the paper forming plate contacts the horizontal guide plate 3, allowing the paper forming plate to maintain a horizontal state after being raised to a horizontal state. Then, the paper forming plate... The paper forming plate is lifted again by the first long bending plate 404, and then reaches the first inclined plate 405, which keeps the paper forming plate in an inclined state. Then the paper forming plate enters the second bending plate, and the lower end of the paper forming plate is folded upward again, finally folding the lower end of the paper forming plate into a vertical state. Finally, it enters the vertical plate 407 and is sent to the next processing step. The paper forming plate is folded three times by the horizontal plate, the long bending plate and the short bending plate to complete the entire folding process. If it is folded only once, the paper forming plate will have a large rebound. Multiple folds can greatly reduce the rebound of the paper forming plate and ensure product quality.
[0029] In addition, the transmission device 1 is existing technology and is a common device on the paste machine, which can achieve the effect of transmitting paper to form a board.
[0030] In this embodiment of the utility model, a first guide rod 401 is fixedly connected to the left end of the lower folding plate 4; a second guide rod 501 is fixedly connected to the left end of the upper folding plate 5, so as to achieve the effect of bending and folding the paper forming plate and avoiding the lower folding plate 4 or the upper folding plate 5 from scratching the paper forming plate.
[0031] In this embodiment of the present invention, the left end of the first guide rod 401 and the second guide rod 501 is provided with a guide slope 408, which facilitates the movement of the paper forming plate along the first guide rod 401 or the second guide rod 501 and avoids the paper forming plate from colliding with the first guide rod 401 or the second guide rod 501 and thus damaging the paper forming plate.
[0032] In this embodiment of the invention, the first long curved plate 404 is 40 centimeters longer than the second long curved plate 504, achieving the effect of step-by-step folding. The first long curved plate 404 is longer than the second long curved plate 504, so that the second paper forming plate 7 enters the first long curved plate 404 later, thereby making the second paper forming plate 7 complete the folding more slowly. This enables the device to achieve step-by-step folding, thereby allowing the device to fold more paper forming plates, such as when the second paper forming plate 7 is long and needs to be covered on the first paper forming plate 6.
[0033] In this embodiment of the utility model, a plurality of first support rods 403 are fixedly connected to the bottom end of the lower folding plate 4; a plurality of second support rods 503 are fixedly connected to the top end of the upper folding plate 5, so as to facilitate the installation of the lower folding plate 4 and the upper folding plate 5; the first support rods 403 and the second support rods 503 can be easily installed on other structures of the paste-making machine.
[0034] In this embodiment of the invention, an inclined guide plate 201 is fixedly connected to the left end of the vertical guide plate 2; this facilitates the paper forming plate entering the rear end of the vertical guide plate 2.
[0035] In this embodiment of the utility model, a support device is provided on the vertical guide plate 2 and the horizontal guide plate 3; to achieve the effect of fixing the vertical guide plate 2 and the horizontal guide plate 3 on the paste-making machine, the vertical guide plate 2 and the horizontal guide plate 3 can be fixedly installed on the paste-making machine by setting screws, connecting plates and support plates or other devices on the vertical guide plate 2 and the horizontal guide plate 3. Due to the variety of installation styles, they are not shown in the figure.
[0036] Working principle: When the upper end of the paper forming plate is clamped on the conveying device 1, it is driven to move to the right by the conveying device 1. When the upper end of the paper forming plate contacts the vertical guide plate 2, the paper forming plate is clamped between the conveying device 1 and the vertical guide plate 2. As the paper forming plate continues to move to the right, the lower end of the paper forming plate contacts the first guide rod 401 of the lower folding plate 4. At this time, the paper forming plate will gradually rise. Then the paper forming plate contacts the horizontal guide plate 3, so that the paper forming plate can maintain a horizontal state after being raised to a horizontal state. Then the paper forming plate enters the first long curved plate 404, so that the lower end of the paper forming plate is raised again, and then reaches the first inclined plate 405, so that the paper forming plate can maintain an inclined state. Then the paper forming plate enters the second bending plate, and the lower end of the paper forming plate is folded upwards again, so that the lower end of the paper forming plate is folded into a vertical state. Finally, it enters the vertical plate 407 and is sent to the next processing step. The folding method of the paper forming plate is similar, only the folding time is different. Because the first long bending plate 404 is 40 centimeters longer than the second long bending plate 504, the second paper forming plate 7 enters the first long bending plate 404 later, so the second paper forming plate 7 completes the folding more slowly. This allows the device to achieve step folding, so that the device can fold more paper forming plates, such as when the second paper forming plate 7 is long and needs to be covered on the first paper forming plate 6.
