Description

Technical Field

[0001] This utility model relates to a lunch box forming machine, and more particularly to a lunch box forming machine with a push-out feeding mechanism. Background Technology

[0002] Existing lunchbox forming machines use a paper feeding mechanism to feed paper sheets to a forming mechanism. The upper and lower molds close to complete the lunchbox forming. The tray rises to detach the lunchbox from the forming groove of the lower mold. An air blowing pipe blows air off the lunchbox to complete the discharge. This process consumes a large amount of air during high-speed production. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a lunch box forming machine with push-out, which is designed to drive the push rod to move longitudinally to realize push-out.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This type of push-out lunch box forming machine includes a paper feeding mechanism, a forming mechanism, and a box dispensing mechanism. The paper feeding mechanism forms a paper feeding path, and the forming mechanism is arranged on the paper feeding path. The forming mechanism includes an upper mold and a lower mold. The upper mold is raised and lowered, and the lower mold includes a raised and lowered support plate. The support plate cooperates with the box dispensing mechanism. The box dispensing mechanism includes a push rod, which is arranged above the paper feeding path. The push rod is connected to a movable seat, which is longitudinally movable. The movable seat is hinged to one end of a drive rod, and a rotating block is rotatably arranged. The other end of the drive rod is hinged to the rotating block, and the hinge point is offset from the rotation center line. The rotating block is driven by a drive motor.

[0005] In this scheme, the drive motor drives the rotating block to rotate once, and the moving seat drives the push rod to move once. By controlling the motor speed, the forming speed of the lunch box can be matched. The hinge point rotates around the rotation center line, causing the drive rod to push and pull the moving seat.

[0006] Preferably, the movable seat is connected to a slider, which is slidably mounted on a longitudinal guide rail.

[0007] In this design, the slider works in conjunction with the longitudinal guide rail to guide the longitudinal movement of the moving seat, ensuring uniform material pushing action.

[0008] Preferably, the longitudinal guide rail is mounted on the mounting plate, the drive motor is mounted on the mounting plate, and the longitudinal movement adjustment of the mounting plate is set on the frame.

[0009] In this design, the longitudinally movable adjustment mounting plate can adjust the length of the push rod extending into the forming mechanism, thereby controlling the material pushing effect.

[0010] Preferably, the pallet is driven by the output shaft of the drive cylinder.

[0011] In this design, the drive cylinder drives the pallet to rise and fall, resulting in stable operation.

[0012] Preferably, the push rod has a pushing position and a avoidance position. The rotating block drives the push rod to reciprocate between the pushing position and the avoidance position. When the push rod is in the avoidance position, the push rod avoids the upper mold. When the push rod is in the pushing position, the push rod is above the pallet.

[0013] In this scheme, when the push rod is in the avoidance position, it avoids the upper mold; when the push rod is in the material pushing position, it extends into the upper part of the tray to push the material.

[0014] Preferably, the push rod is detachably connected to the movable seat.

[0015] In this solution, the feeding effect can also be controlled by changing the length of the push rod.

[0016] Preferably, it also includes a box collection mechanism, which includes a box guide slide and a box stacking compartment. The box guide slide connects the forming mechanism and the box stacking compartment. The box stacking compartment includes a rear baffle and a side baffle. The rear baffle is longitudinally adjustable.

[0017] In this design, the guide rails guide the food containers pushed by the push rods into the stacking compartment for stacking. Adjusting the rear baffle and side baffles can accommodate the stacking of food containers of different sizes.

[0018] The beneficial effects of this utility model are as follows: for every revolution of the rotating block driven by the drive motor, the moving seat drives the push rod to move once; controlling the motor speed can match the forming speed of the lunch box; the slider and the longitudinal guide rail cooperate to guide the longitudinal movement of the moving seat, ensuring uniform material pushing action. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0028] See appendix Figure 1-4 This embodiment of the invention provides a push-out food box forming machine, which includes a paper feeding mechanism, a forming mechanism 1, a box ejection mechanism 2, and a box collection mechanism 14. The paper feeding mechanism forms a paper feeding path, and the forming mechanism 1 is disposed on the paper feeding path. The forming mechanism 1 includes an upper mold 3 and a lower mold 4. The upper mold 3 is raised and lowered, and the lower mold 4 includes a raised and lowered support plate 5. The support plate 5 is driven by a drive cylinder output shaft. The support plate 5 cooperates with the box ejection mechanism 2. The box collection mechanism 14 includes a guide slide 15 and a stacking bin 16. The guide slide 15 connects the forming mechanism 1 and the stacking bin 16. The stacking bin 16 includes a rear baffle 17 and a side baffle 18. The rear baffle 17 is longitudinally adjustable.

[0029] The ejector mechanism 2 includes a push rod 6, which is positioned above the paper feed path. The push rod 6 is connected to a movable seat 7, which is connected to a slider 11. The slider 11 is slidably mounted on a longitudinal guide rail 12. The movable seat 7 is hinged to one end of a drive rod 8. A rotating block 9 is rotatably mounted. The other end of the drive rod 8 is hinged to the rotating block 9, and the hinge point is offset from the rotation center line. The rotating block 9 is connected to a drive motor 10. The longitudinal guide rail 12 is mounted on a mounting plate 13, and the drive motor 10 is mounted on the mounting plate 13. The mounting plate 13 is longitudinally adjustable on the frame. The push rod 6 has a pushing position and a retraction position. The rotating block 9 drives the push rod 6 to reciprocate between the pushing position and the retraction position. When the push rod 6 is in the retraction position, it avoids the upper mold 3. When the push rod 6 is in the pushing position, it is positioned above the tray 5. The push rod 6 is detachably connected to the movable seat 7.

[0030] In this embodiment, the paper feeding mechanism (not shown in the figure) specifically consists of a pusher block and a paper support guide rail. The pusher block pushes the paper sheet along the paper support guide rail to the pallet 5. The upper mold 3 descends and clamps the paper sheet with the pallet 5, closing with the lower mold 4 to press the paper sheet into a paper box. The upper mold 3 resets, and the drive cylinder drives the pallet 5 to rise, taking the paper box away from the lower mold 4. The drive motor 10 drives the rotating block 9 to rotate into position, and the moving seat 7 drives the push rod 6 to push the paper box on the pallet 5 into the guide box slide 15. The paper boxes move in a queue along the guide box slide 15 and fall into the stacking bin 16 for stacking. The paper feeding method can also be clamping, and the paper feeding direction can be horizontal or vertical. The paper sheet can be fed by a suction nozzle from the bin and then pushed by the pusher block. The forming mechanism 1 is a mature technology. The motor rotates continuously, with low energy consumption and convenient speed adjustment. The hinge point is wound. The adjustment method can be that the fastener passes through the long slot and is threadedly connected to the threaded hole. Adjustment can be achieved by adjusting the position of the fastener in the long slot.

[0031] In other alternative implementations, the tray 5 can also be raised and lowered using the elastic force of the elastic element.

[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.
