Description

Technical Field

[0001] This utility model relates to a three-dimensional packaging machine, and more particularly to a three-dimensional packaging machine suitable for irregularly shaped materials. Background Technology

[0002] Existing 3D packaging machines use coated paper to wrap materials and heat-seal the middle and sides. The proposed method is to use ordinary paper to wrap materials and seal the middle and sides with adhesive. After applying the adhesive, a pressure plate is used for sealing and bubble compression. However, when the material is irregularly shaped, the upper surface of the material cannot be effectively supported, and bubble compression is inadequate. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a three-dimensional packaging machine suitable for irregularly shaped materials, wherein the intermediate sealing is completed by line contact of the pressure roller to compress the bubble, and the bubble is compressed in place.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This three-dimensional packaging machine suitable for irregularly shaped materials includes a first pusher, a feeding platform, a discharging platform, and a turret. The first pusher is spaced apart on a first chain, and the first chain drives the first pusher to move longitudinally. The discharging platform has a first longitudinal opening for the first pusher to pass through and move longitudinally. The turret connects the feeding platform and the discharging platform. The turret includes a main body and a clamping assembly. The main body is rotatably arranged, and the rotation center line of the main body extends horizontally. The main body includes a first mounting frame and a second mounting frame. A pushing gap is formed between the first mounting frame and the second mounting frame for the first pusher to pass through. The clamping assembly is distributed circumferentially along the main body. The turret has a central glue spraying assembly circumferentially. The central glue spraying assembly includes a cooperating central glue spraying head and a backing plate. The feeding side of the discharging platform has a side baffle and a pressure roller. The discharging platform has a material supporting surface. There is a gap between the material supporting surface and the lower edge of the side baffle for the ear to pass through. The pressure roller is arranged above the side baffle.

[0005] In this scheme, the paper-covered material is placed in the clamping assembly. When the turret carries the material to the middle glue spraying assembly, the paper surface to be bent is pressed against the backing plate. The middle glue spraying head applies glue to the bonding area. The first pusher pushes the material out of the clamping assembly. The pressure roller flattens the glued paper surface and presses it against another paper surface that has been bent into place.

[0006] Preferably, the intermediate spray nozzle is configured to move laterally.

[0007] In this design, the middle spray nozzle moves laterally to avoid the paper surface to be sprayed with glue.

[0008] Preferably, the material feeding side of the discharge platform is also provided with a pressure plate, which is lifted and positioned above the side baffle to define the material conveying direction as from front to back, and the pressure plate is located in front of the pressure roller.

[0009] In this scheme, the pressure plate presses down to initially bond the glued paper surface with another bent paper surface, and then the pressure roller completes the bubble pressing.

[0010] Preferably, the feed end of the pressure plate is connected to a folding board, which is inclined.

[0011] In this scheme, the folding of the cardboard causes the paper surface after spraying glue to be folded over and face another paper surface that has been bent into place.

[0012] Preferably, the clamping assembly includes a left clamp and a right clamp, each of which includes a top plate, a bottom plate, and a side plate. A gap for accommodating the folding lug is formed between the upper ends of the top plate and the side plate, and between the lower ends of the bottom plate and the side plate.

[0013] In this design, the bottom plate, side plates, and top plate work together to maintain the folded ear effect.

[0014] Preferably, the discharge platform is further provided with a first folding plate and a second folding plate in sequence. The first folding plate has a first folding edge line, and the second folding plate has a second folding edge line. Both the first folding edge line and the second folding edge line are inclined relative to the material conveying direction. The first folding edge line and the second folding edge line are V-shaped. The first folding plate is provided with a through hole for the side spray nozzle to be exposed.

[0015] In this scheme, the upper and lower ears of the packaging paper are bent along the first fold line and the second fold line, respectively. The side spray nozzle applies glue to the bent ears, so that the two ears are glued together after the other ear is folded into place.

[0016] Preferably, a gap is formed between the lower edge of the first folding ear plate and the material support surface to allow the ear to pass through, and the lower edge of the second folding ear plate is lower than the lower edge of the first folding ear plate.

[0017] In this design, the lower ear can contact and fold over the edge of the second folded ear through the gap.

[0018] Preferably, the discharge platform is further provided with a guide plate to define the material conveying direction as from front to back. The guide plate is located in front of the first folding plate, the upper edge of the guide plate is lower than the upper edge of the first folding plate, and a gap is formed between the lower edge of the guide plate and the material support surface to allow the ear to pass through.

[0019] In this design, the upper ear contacts and folds along the upper edge of the guide ear with the first folded ear edge, while the lower ear can contact and fold through the gap with the second folded ear edge.

[0020] Preferably, the first folding plate has a limiting edge line, the limiting edge line and the second folding edge line form a folding channel, and the through hole communicates with the folding channel.

[0021] In this design, the glue applied to the bent ear section will not come into contact with the first folding ear plate.

[0022] Preferably, the discharge platform is further provided with a bubble pressing plate, which is configured to move laterally.

[0023] In this design, the laterally moving pressing plate presses the upper and lower ears together, eliminating air bubbles and ensuring a good bonding effect.

[0024] The beneficial effects of this utility model are as follows: the paper-covering material is placed in the clamping assembly; when the turret carries the material to the intermediate glue spraying assembly, the paper surface to be bent rests against the backing plate; the intermediate glue spraying head applies glue to the area to be bonded; the first pusher pushes the material out of the clamping assembly; and the pressure roller flattens the glued paper surface and bonds it to the other bent paper surface, thus pressing the bubble into place. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0037] See appendix Figure 1-26. In an embodiment of this invention, a three-dimensional packaging machine suitable for irregularly shaped materials includes a first pusher head, a feeding platform 1, a discharging platform 36, and a turret 13. The first pusher head is spaced along a first chain, which drives the first pusher head to move longitudinally. The discharging platform 36 has a first longitudinal opening 37 for the first pusher head to pass through and move longitudinally. The turret 13 connects the feeding platform 1 and the discharging platform 36. The turret 13 includes a main body 23 and a clamping assembly 24. The main body 23 is rotatably disposed, and the rotation center line of the main body 23 is along... Extending horizontally, the main body 23 includes a first mounting bracket 34 and a second mounting bracket 35. A pushing gap is formed between the first mounting bracket 34 and the second mounting bracket 35 for the first pusher head to pass through. The clamping assembly 24 is distributed circumferentially along the main body 23. The clamping assembly 24 includes a left clamp 25 and a right clamp 26. Both the left clamp 25 and the right clamp 26 include a top plate 27, a bottom plate 28, and a side plate 29. Gap for accommodating folding ears is formed between the top plate 27 and the upper end of the side plate 29, and between the bottom plate 28 and the lower end of the side plate 29.

[0038] The turret 13 is provided with an intermediate glue spraying assembly 30 around its circumference. The intermediate glue spraying assembly 30 includes an intermediate glue spraying head 32 and a backing plate 33 that cooperate with each other. The intermediate glue spraying head 32 is arranged to move laterally. The discharge platform 36 is provided with a side baffle 40, a pressure plate 39 and a pressure roller 2 on the feeding side. The discharge platform 36 has a material support surface 3. There is a gap between the material support surface 3 and the lower edge of the side baffle 40 for the ear to pass through. The pressure roller 2 is arranged above the side baffle 40. The pressure plate 39 is raised and lowered above the side baffle 40, defining the material conveying direction as from front to back. The pressure plate 39 is located in front of the pressure roller 2. The feeding end of the pressure plate 39 is connected to a folding paper 4, which is inclined.

[0039] In this embodiment, a paper-wrapping mechanism is provided on the feeding platform 1. The material is pushed along the feeding platform 1 by the second pusher, and after being folded out by the folding ear assembly, it enters the clamping assembly 24 of the turret 13. This is a mature technology. The material is defined as having six sides: A, B, C, D, E, and F, where E and F are the sides. The feeding direction is from front to back (longitudinal). At the paper-wrapping mechanism, side B of the material is covered by the paper tape, and part of side A presses down on the end of the paper tape to form a paper surface to be sealed. The clamping assembly 24 receives the material pushed by the second pusher. The gap of the clamping assembly 24 maintains the folded state of the ear. The material is conveyed longitudinally on both the discharge platform 36 and the feeding platform 1. Therefore, the material rotates 180 degrees under the drive of the turret 13 to complete the flipping. At the middle glue spraying assembly 30, the paper surface to be sprayed is attached to the backing plate 33, and the glue spraying position is exposed. The middle glue spraying head 32 moves laterally into position to spray the paper surface. The adhesive is sprayed onto the paper surface. The turret 13 continues to rotate. The lower end of the plate 33 or the folding board 4 causes the sprayed paper surface to bend and cover the C side, forming a crease line. The material A side faces up and the D side faces back. The first pusher pushes the material from the clamp assembly 24 into the discharge platform 36 through the pushing gap. The sprayed paper surface is bent under the action of the front end of the pressure plate 39 and faces the paper surface to be sealed, which has already covered the A side. The side baffle 40 causes the D side of the paper to bend forward and form a crease line, forming another corner of the ear for sealing. The pressure plate 39 presses down to make the two paper surfaces stick together. The middle spray head 32 can also use other movement trajectories, as long as it can avoid the paper surface to be sprayed. The pressure plate 39 and the pressing plate can be controlled to heat the pressing plate to act as a heat sealing plate, which can complete the heat sealing and is compatible with the packaging of coated paper. Alternatively, the pressure plate 39 and the pressing plate can be replaced with a heat sealing plate. The pressure roller 2 can be raised and lowered for easy installation.

[0040] See appendix Figure 3-5 7. The discharge platform 36 is further provided with a guide plate 42, a first folding plate 44, a second folding plate 47, and a foam pressing plate 49 in sequence. The first folding plate 44 has a first folding edge line 6, and the second folding plate 47 has a second folding edge line 7. Both the first folding edge line 6 and the second folding edge line 7 are inclined relative to the material conveying direction and are V-shaped. The first folding plate 44 has a through hole 46 exposed by the side spray nozzle 52. The lower edge of the first folding plate 44... A gap is formed between the second ear plate 47 and the material support surface 3 to allow the ear to pass through. The lower edge of the second ear plate 47 is lower than the lower edge of the first ear plate 44, and the upper edge of the guide plate 42 is lower than the upper edge of the first ear plate 44. A gap is formed between the lower edge of the guide plate 42 and the material support surface 3 to allow the ear to pass through. The first ear plate 44 has a limiting edge line 5. The limiting edge line 5 and the second ear edge line 7 form an ear folding channel. The through hole 46 communicates with the ear folding channel. The bubble pressing plate 49 is laterally movable.

[0041] In this embodiment, the upper ear on the side of the packaging paper is defined as the upper ear, and the lower ear as the lower ear. The upper ear can be folded first, or the lower ear can be folded first, by adjusting the tilt angle of the corresponding ear edge. The first pusher pushes the material with the packaging paper to move longitudinally. The upper ear on the side of the paper packaging contacts the first ear edge 6 along the upper edge of the guide plate 42 and gradually bends. The side glue spray head 52 sprays glue on the part of the upper ear to be glued after bending. The lower ear enters the ear channel 48 along the gap and gradually bends along the second ear edge 7 to fit with the upper ear after bending. The bubble depressing plate 49 moves laterally to press the upper and lower ears together and eliminate air bubbles. The through hole 46 is connected to the ear channel so that the glue does not come into contact with the first ear plate 44. The glue spray head is a mature technology. The gap keeps the lower ear to be bent in a bent state to avoid affecting the bending of the upper ear.

[0042] 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.
