Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cardboard processing, in particular to a cardboard pulling mechanism. Background Art
[0002] Before packaging products with cardboard, each piece needs to be printed with specific images or text. During the cardboard printing process, the sheets are laid flat on the printing table for printing. Since the sheets are typically stacked, transferring them to the printing table is typically done manually. This manual transfer process not only increases the workload but also is inefficient, significantly impacting production schedules when handling large quantities of cardboard. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a cardboard pulling mechanism to solve the problem of low efficiency in the current cardboard transfer process.
[0004] The technical solutions adopted in this utility model are as follows:
[0005] The cardboard pulling mechanism includes a frame, a placement table for stacking cardboards is provided on the frame, a first channel is provided in the middle of the placement table, and a pulling component for pulling cardboards is also provided on the frame. The pulling component includes an adsorption plate that can be extended into the first channel, a cavity is provided in the adsorption plate, and the cavity is connected to a negative pressure device. An adsorption hole connected to the cavity is opened on the top of the adsorption plate, and the adsorption plate can use the adsorption hole to adsorb the bottom of the cardboard. A connecting rod is fixed to the lower side of the adsorption plate, and a driving component is connected to the connecting rod. The driving component drives the connecting rod and the adsorption plate to move back and forth horizontally.
[0006] Compared with the existing technology, the principle and beneficial effects of this utility model are:
[0007] In this solution, the sheets are stacked on the table. When the suction plate extends into the first channel, it lies beneath the bottom sheet. The negative pressure device activates, gripping the sheet with the suction plate. The drive assembly then pulls the sheet and the sheet to the appropriate position on the printing table. The negative pressure device stops, and the process repeats for the next sheet. This pull assembly replaces manual sheet handling, reducing the workload and improving transfer efficiency. This helps speed up production, especially when handling large quantities of sheets.
[0008] As a preferred embodiment of the present invention, the drive assembly includes a pull rope and a winding roller. One end of the pull rope is fixed to a connecting rod, and the other end is wound on the winding roller. The rotating shaft of the winding roller is connected to a servo motor. A spring is fixed to the side of the connecting rod away from the pull rope, and the spring is used to drive the connecting rod to reset when the pull rope is released. The connecting rod is also provided with a guide assembly for guiding the adsorption plate. In this solution, when the servo motor drives the winding roller to rotate forward, the pull rope is tightened and begins to reel. At this time, the pull rope pulls the connecting rod and the adsorption plate to one side horizontally, and the spring stretches. Conversely, when the servo motor drives the winding roller to reverse, the pull rope begins to release. At this time, the connecting rod moves in the opposite direction under the action of the spring elastic force, and the spring resets. The drive structure adopted in this solution is simple, which helps to save equipment costs.
[0009] As a preferred embodiment of the present invention, the guide assembly includes a T-shaped slider disposed at the lower end of the connecting rod, and a T-shaped chute is provided on the frame to cooperate with the T-shaped slider. In this solution, the cooperation between the T-shaped slider and the T-shaped chute can guide the connecting rod, thereby guiding the suction plate and the cardboard, making the cardboard pulling process smoother.
[0010] As a preferred embodiment of the present invention, the negative pressure device is a vacuum machine.
[0011] As a preferred embodiment of the present invention, the upper end surface of the suction plate is flush with the upper end surface of the placement table. By setting the upper end surface of the suction plate flush with the upper end surface of the placement table, this solution allows the suction plate to precisely contact the underside of the cardboard, ensuring that the cardboard will not deform during the suction process. If the suction plate is lower than the placement table, the downward suction force generated during the suction process will cause the middle of the cardboard to sag, thereby causing the cardboard to deform. Therefore, this arrangement can prevent the cardboard from deforming during the pulling process.
[0012] As a preferred embodiment of the present invention, the four corners of the placement table are provided with L-shaped horizontal cross-section columns, which are used to limit the circumferential displacement of the stacked cardboards. The columns in this solution have a simple structure and can effectively limit the displacement of the upper cardboard when the bottom cardboard is pulled.
[0013] As a preferred embodiment of the present invention, a printing platform is provided on one side of the placement platform. A second channel for the reciprocating motion of the suction plate is provided in the middle of the printing platform. The upper end surface of the printing platform is flush with the upper end surface of the placement platform. The lower portions of the two uprights near the printing platform each have an escape slot for the bottom layer of cardboard to pass through. The escape slot provided in this solution not only facilitates the passage of cardboard, but also serves as a guide for the pulled cardboard, preventing it from shifting left or right during the pulling process.

[0020] See also Figure 1 and Figure 2 As shown, this embodiment discloses a cardboard pulling mechanism, comprising a frame 1, mounted with a printing table 5 and a placement table 2 for stacking cardboards 16. The printing table 5 is located on one side of the placement table 2 and is flush with the upper end surface of the placement table 2. The placement table 2 has four corners integrally formed with upright posts 3 having an L-shaped horizontal cross-section. Each upright post 3 has its right angle facing inward and mates with the four corners of the cardboard 16. The provision of these four upright posts 3 restricts the circumference of the stacked cardboards 16, preventing them from falling.
[0021] The middle of the placement table 2 and the printing table 5 are respectively provided with a first channel 6 and a second channel 7. The first channel 6 and the second channel 7 are provided with a pulling component for pulling the cardboard 16 on the placement table 2 to the printing table 5. Specifically, the pulling component includes an adsorption plate 8. The upper end surface of the adsorption plate 8 is flush with the upper end surface of the printing table 5 and the placement table 2. A cavity is provided inside the adsorption plate 8, and the cavity is connected to a negative pressure device. In this solution, the negative pressure device is a vacuum machine, and the vacuum machine is connected to the cavity through a pipe. An adsorption hole is provided on the top of the adsorption plate 8, and the adsorption hole is connected to the cavity. When in use, the adsorption plate 8 can use the negative pressure to adsorb the cardboard 16 and then pull it. Among them, the lower parts of the two columns 3 close to the printing table 5 are respectively provided with an avoidance groove 4. When the adsorption plate 8 pulls the cardboard 16, the avoidance groove 4 can ensure that the bottom cardboard 16 can pass through the column 3 smoothly and be pulled to the printing table 5.
[0022] A connecting rod 9 is fixed to the lower side of the adsorption plate 8, and a driving assembly and a guide assembly are connected to the connecting rod 9. The driving assembly is used to drive the connecting rod 9 and the adsorption plate 8 to reciprocate horizontally, and the guide assembly is used to guide the adsorption plate 8. Specifically, the driving assembly includes a pull rope 11, a winding roller 10 and a servo motor 12. The winding roller 10 is installed on the frame 1 and is located on the side of the printing table 5 away from the placement table 2. The rotating shaft of the winding roller 10 is connected to the servo motor 12. One end of the pull rope 11 is fixed to the connecting rod 9, and the other end is wound on the winding roller 10. A spring 14 is installed on the side of the connecting rod 9 away from the pull rope 11. A mounting plate 15 is installed in the first channel 6, and the other end of the spring 14 is fixed to the mounting plate 15. During use, the servo motor 12 drives the winding roller 10 to rotate forward, the pull rope 11 is tightened and starts to rewind, at this time the pull rope 11 pulls the connecting rod 9 and the adsorption plate 8 to move toward the side of the printing table 5, and the spring 14 is stretched. Conversely, when the servo motor 12 drives the winding roller 10 to reverse, the pull rope 11 starts to release, at this time the connecting rod 9 moves in the opposite direction under the action of the elastic force of the spring 14, and the spring 14 is reset.
[0023] The guide assembly includes a T-shaped slider installed at the lower end of the connecting rod 9, and a T-shaped slide 13 that cooperates with the T-shaped slider is installed on the frame 1. Through the cooperation of the T-shaped slider and the T-shaped slide 13, the connecting rod 9 and the adsorption plate 8 can be guided, making the pulling process smoother.
[0024] Specific implementation process:
[0025] When using this solution, the cardboard 16 is stacked on the placement table 2, and the servo motor 12 first drives the winding roller 10 to reverse and release the pull rope 11. At this time, the adsorption plate 8 moves to the side of the placement table 2 under the action of the spring 14 until the adsorption plate 8 extends to the bottom of the bottom cardboard 16. Then the vacuum machine is started, and the adsorption plate 8 uses negative pressure to adsorb the bottom cardboard 16. Then the winding roller 10 is driven to rotate forward and the pull rope 11 is reeled in. At this time, the pull rope 11 pulls the adsorption plate 8 and the bottom cardboard 16 toward the printing table 5 until the cardboard 16 reaches the appropriate position on the printing table 5. The vacuum machine stops and the cardboard 16 is placed on the printing table 5. Then the above steps are repeated to continue to pull the next cardboard 16.
[0026] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
