Description

Technical Field

[0001] This utility model relates to the field of cardboard box equipment technology, specifically a semi-automatic paper feeding machine with central positioning. Background Technology

[0002] Semi-automatic paper feeding machines are cardboard feeding devices that require manual paperboard addition and automatically feed paper. They are widely used in cardboard box production and packaging. Existing semi-automatic paper feeding machines can only perform the paper feeding action and lack the function of centering the cardboard. Since cardboard boxes need to move along the center line of the production line during processing, the position of the cardboard needs to be manually adjusted in advance when adding cardboard. Current technology uses forklifts to add cardboard, and centering the cardboard is cumbersome, time-consuming, and labor-intensive, hindering efficient production. These shortcomings urgently require improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a semi-automatic paper feeder with a centered positioning function, which solves the problem that existing semi-automatic paper feeders lack the function of adjusting and centering the paperboard position, thus hindering efficient production.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A semi-automatic paper feeder with centered positioning includes a fixed frame and a flipping frame connected to the fixed frame via a transmission shaft. An overhead guide rail is fixedly installed on the front of the fixed frame. A support frame for supporting paperboard is installed on the flipping frame. There are two overhead guide rails arranged symmetrically on the left and right. A transverse limiting guide rail is fixedly installed below each of the two overhead guide rails via a connecting frame. An L-shaped centered positioning plate is slidably connected within each of the two limiting guide rails. The paperboard is located between the vertical plates of the two centered positioning plates. A drive push rod is provided at the bottom of the front of the fixed frame. A connecting seat is fixedly installed at the piston rod end of the drive push rod. A transmission connecting rod is movably hinged between the connecting seat and each of the two centered positioning plates.

[0006] Preferably, the support frame is mounted on the transmission chain on the tilting frame, and there are three sets of support frames and transmission chains, with the support frame and the overhead guide rail spaced apart.

[0007] Preferably, the distance between the opposing surfaces of the two overhead guide rails is less than the distance between the two forks of the forklift transporting the cardboard, and the vertical distance between the opposing surfaces of the two overhead guide rails and the opposing support frame is greater than the width of a single fork of the forklift transporting the cardboard.

[0008] Preferably, the limiting guide rail is a roller limiting guide rail with a rotating roller set at the position corresponding to the center positioning plate.

[0009] Preferably, a first support roller is installed on the bottom of the opposite side of both of the central positioning plates.

[0010] Preferably, a second support roller is installed at the bottom of the connecting seat.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention, through the setting of a limiting guide rail, a centering positioning plate, a drive push rod, a connecting seat, and a transmission link, allows the cardboard to be transported onto the support frame. The drive push rod pushes the connecting seat, which, through the transmission link, simultaneously pulls the two centering positioning plates towards the center under the guidance and limiting action of the limiting guide rail. The centering positioning plates move closer to each other, thereby centering the cardboard. The operation is simple and convenient, saving time and effort, and improving efficiency. It solves the problem that the existing semi-automatic paper feeding machine does not have a cardboard position adjustment and centering function, which is not conducive to efficient production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a semi-automatic paper feeding machine with central positioning, including a fixed frame 1 and a flipping frame 3 connected to the fixed frame 1 by a transmission shaft 2. An overhead guide rail 4 is fixedly installed on the front of the fixed frame 1. A support frame 6 for supporting paperboard 5 is installed on the flipping frame 3. There are two overhead guide rails 4, which are symmetrically arranged on the left and right. The support frame 6 is installed on the transmission chain 13 on the flipping frame 3. There are three sets of support frames 6 and transmission chains 13. The support frame 6 is spaced apart from the overhead guide rail 4 for stable support and lifting of paperboard 5.

[0021] The distance between the opposing surfaces of the two overhead guide rails 4 is less than the distance between the two forks of the forklift that transports the cardboard 5. The vertical distance between the opposing surfaces of the two overhead guide rails 4 and the opposite support frame 6 is greater than the width of a single fork of the forklift that transports the cardboard 5, making it easier for the forklift to transport the cardboard 5 onto the overhead guide rails 4.

[0022] Below each of the two overhead guide rails 4, a horizontal limiting guide rail 8 is fixedly installed via a connecting frame 7. Each of the two limiting guide rails 8 has an L-shaped centering positioning plate 9 slidably connected inside. The limiting guide rail 8 is a roller limiting guide rail with a rotating roller set at the position of the corresponding centering positioning plate 9, which facilitates the movement of the centering positioning plate 9 and guides and limits it. The cardboard 5 is located between the vertical plates of the two centering positioning plates 9.

[0023] A drive push rod 10 is provided on the bottom front of the fixed frame 1. A connecting seat 11 is fixedly installed at the piston rod end of the drive push rod 10. A transmission connecting rod 12 is movably hinged between the connecting seat 11 and the two center positioning plates 9. A first support roller 14 is installed on the bottom of the opposite side of the two center positioning plates 9. A second support roller 15 is installed on the bottom of the connecting seat 11.

[0024] Working principle:

[0025] The cardboard 5 is moved onto the overhead guide rail 4 by a forklift. The cardboard 5 is pushed backward on the overhead guide rail 4 to move above the support frame 6. The drive rod 10 pushes the connecting seat 11 forward. The connecting seat 11 pulls the two centering positioning plates 9 simultaneously through two left and right symmetrical transmission links 12. Under the guidance and limiting action of the limiting guide rail 8, the centering positioning plates 9 move towards each other and push the cardboard 5 towards the center, thereby adjusting the position of the cardboard 5 to make it center. The operation is simple and convenient.
