Technical Field

[0001] This utility model relates to a paper box edge rolling machine, and more particularly to a paper box edge rolling machine with rotary feeding. Background Technology

[0002] In existing paper box edge rolling machines, the turntable drives the forming bottom mold through each station in sequence to perform edge folding and rolling. The paper box is formed at the same time as the edge folding. Since each process shares a forming bottom mold and the forming is carried out on the turntable, the setting of the forming bottom mold and the forming pressure of the paper box are both limited. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a rotary feeding paper box edge rolling machine with an independently designed pre-forming station, which first forms the paper box, increases the forming pressure, and improves the forming effect.

The material transfer seat is rotatably arranged, and the material transfer nozzle is raised and lowered.

[0005] In this solution, an independent pre-forming station increases the pressure of cardboard box forming. While one set of material transfer nozzles picks up material at the pre-forming station, another set of material transfer nozzles releases material at the loading station, resulting in fast loading speed.

[0015] In this scheme, the motor drives the lifting seat to move down through the lead screw, the support arm swings down, the first pressure arm unfolds to both sides, and the second pressure arm is pulled up, so that the force of the support arm on the upper mold support plate tends to be vertical, the mold closing pressure is sufficient, and the connecting column guides the lifting and lowering of the upper mold support plate.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0026] See appendix Figure 1-2 In this embodiment, a rotary feeding paper box edge rolling machine includes a pre-forming station, a feeding station, and a final forming station. The feeding station and the final forming station are connected by a turntable 1. A lower forming mold 28 is disposed on the turntable 1 and distributed circumferentially along the turntable 1. The final forming station is equipped with a final forming upper mold.

[0027] The preforming station is equipped with a preforming upper mold 2 and a preforming bottom mold 3. A transfer assembly 4 is connected between the preforming station and the loading station. The transfer assembly 4 includes a transfer seat 5 and a transfer nozzle 6. The transfer nozzle 6 is distributed circumferentially along the transfer seat 5 and there are at least two sets. The transfer seat 5 is rotatably set. The transfer nozzle 6 is set at one end of a fixed plate 13. The other end of the fixed plate 13 is connected to the output shaft of a cylinder 14. The cylinder 14 is set on the transfer seat 5. The fixed plate 13 is connected to a guide post 15. The transfer seat 5 is provided with a guide sleeve 16 corresponding to the guide post 15. The transfer seat 5 has a transfer state and a waiting state. The transfer seat 5 rotates to switch between the transfer state and the waiting state. When the transfer seat 5 is in the waiting state, the transfer nozzle 6 avoids the preforming upper mold 2.

[0028] In this embodiment, the feeding method at the preforming station can be a push-feed method. The paper to be formed is pushed out from the hopper and pushed along the feeding guide to the top of the preforming bottom mold 3. This feeding method is a mature technology. The preforming upper mold 2 presses down to complete the preforming. The transfer seat 5 rotates from the waiting state to the transfer state. The two sets of transfer nozzles 6 move to the top of the preforming bottom mold 3 and the forming lower mold 28 at the feeding station, respectively. The cylinder 14 drives the fixing plate 13 to move the transfer nozzles 6 down to pick up and put down the paper box. The transfer seat 5 rotates again from the transfer state. Switching to the waiting state, the turntable 1 drives the forming lower mold 28 to rotate in each station. The preforming upper mold 2 presses down and cooperates with the preforming bottom mold 3 to preform the paper sheet that is fed in again. This cycle repeats. The transfer seat 5 is connected to the transfer motor, which is mounted on the motor mounting base. With one less preforming station, the size of the forming lower mold 28 can be increased to accommodate the production of larger paper boxes while keeping the area of ​​the turntable 1 unchanged. The folding and rolling processes are mature technologies, and the corresponding upper mold structure is also a mature technology.

[0029] In other alternative implementations, the motor mounting base can be raised and lowered, allowing the cardboard box to be moved after preforming for the transfer nozzle 6 to pick up, thus eliminating the need for the transfer nozzle 6 to avoid the preforming upper mold 2.

[0030] See appendix Figure 2-4The preformed bottom mold 3 is equipped with a corner block 7 and a baffle 8. The forming lower mold 28 includes a curling plate 9 and a positioning lower mold 10. The curling plate 9 is connected to the positioning lower mold 10 by bolts 11. A spring 12 is sleeved on the bolt 11, and the spring 12 abuts against the curling plate 9 and the positioning lower mold 10 respectively. The preformed upper mold 2 is located below the upper mold support plate 17. The upper mold support plate 17 is sleeved on the connecting column 18. The upper mold support plate 17 is connected to the lifting seat 19. The lifting seat 19 is threadedly engaged with the lead screw 20. The lead screw 20 is connected to the preforming motor 21. The first pressure arm 22, the second pressure arm 23, and the support arm 24 are hinged to the same axis. The other end of the first pressure arm 22 is hinged to the pressure arm connecting plate 25, which is located below the lifting seat 19. The other end of the second pressure arm 23 is hinged to the upper mold support plate 17. The other end of the support arm 24 is hinged to the pressure arm hanging plate 26, which is located on the fixed seat 27. The preforming motor 21 is located on the fixed seat 27. The connecting column 18 is connected to the fixed seat 27.

[0031] In this embodiment, when the mold is closed, the motor drives the lead screw 20 to rotate, the lifting seat 19 moves down, the support arm 24 swings down, the first pressure arm 22 unfolds to both sides, and the second pressure arm 23 is pulled up. Ideally, the first pressure arm 22 is flush with the lifting seat 19, and the support arm 24 and the second pressure arm 23 are in a vertical state. The vertical force on the lifting seat 19 can be transmitted to the pre-forming upper mold 2 through the second pressure arm 23, resulting in minimal force loss. The motor and the lead screw 20 are driven by a synchronous belt and a synchronous pulley. The paper sheet is attached to the baffle plate. 8. To push the paper into place, the top surfaces of the two corner blocks 7 can support the paper. The two corner blocks 7, together with the pre-forming upper mold 2, first fold out the four corners of the paper box and stand up the sides. The edge rolling plate 9, together with the corresponding upper mold, presses down the outer edge or outer rolled edge of the paper box. The edge rolling plate 9 is provided with through holes for the rod of the bolt 11 to pass through. The rod is threadedly connected to the positioning lower mold 10. The spring 12 makes the edge rolling plate 9 and the head of the bolt 11 press against each other. The pressure arm connecting plate 25 connects the four first pressure arms 22, the upper mold support plate 17 connects the four second pressure arms 23, and there are two support arms 24.

[0032] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
