Description

Technical Field

[0001] This utility model relates to a three-dimensional packaging machine, and more particularly to a three-dimensional paper packaging machine for soap. Background Technology

[0002] Existing three-dimensional soap packaging machines wrap soap in film and use heat sealing to seal the middle and sides. The proposed solution is to wrap the soap in ordinary paper and seal the middle and sides with adhesive to save costs. However, ordinary paper does not have heat shrink properties, resulting in a large gap between the packaging paper and the soap, and the packaging is not tight enough. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a three-dimensional paper packaging machine for soap, which is designed to have the first pressure roller press the outer packaging paper along the outer contour of the soap after the folding ear, so that the fold line is close to the soap.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This three-dimensional paper packaging machine for soap includes a first pusher and a paper wrapping platform. The paper wrapping platform has a first opening for the first pusher to pass through and move longitudinally. The paper wrapping platform is provided with a first paper wrapping mechanism and a first folding ear assembly in sequence along the longitudinal direction. The first folding ear assembly includes a first upper insert plate, a first side insert plate, and a first pressure roller. The first upper insert plate and the first pressure roller are sequentially arranged above the first side insert plate. Gap gaps for accommodating the ear are provided between the upper end of the first upper insert plate and the first side insert plate, and between the paper wrapping platform and the lower end of the first side insert plate.

[0005] In this design, the soap is pushed by the first pusher and goes through the wrapping paper and folding ears in sequence. After the ears are folded, the outer packaging paper comes into contact with the first pressure roller and is pressed to adhere to the surface of the soap, and the fold line is shaped.

[0006] Preferably, the feeding end of the paper wrapping platform is equipped with a feeding mechanism, which includes a feeding conveyor belt and a feeding pusher. The feeding conveyor belt is in a longitudinal direction, and a laterally movable feeding pusher is provided above the feeding conveyor belt. The paper wrapping platform is equipped with a second paper wrapping mechanism. Both the first paper wrapping mechanism and the second paper wrapping mechanism include a traction roller group and a cutting component. The traction roller group and the cutting component are arranged sequentially in a vertical direction. The traction roller group pulls to form a paper strip, and the first opening extends to both sides with transverse openings for the paper strip to pass through.

[0007] In this scheme, the feeding pusher pushes the soap delivered by the feeding conveyor belt onto the wrapping platform. The first wrapping mechanism and the second wrapping mechanism wrap the soap with two layers of paper, and the inner layer of paper is responsible for absorbing water and drying.

[0008] Preferably, a support plate for supporting the first push head is provided below the first opening, an installation shaft is provided between the two sets of first chains, the first push head is oscillatingly mounted on the installation shaft, and notches are provided on both sides of the first push head for the paper wrapping platform to pass through. The first opening is connected to a push head passage, and the push head passage is equipped with a top block, which drives the first push head to oscillate.

[0009] In this design, the top block drives the first pusher to swing, causing the first pusher to separate from the soap, thus avoiding excessive pushing.

[0010] Preferably, it also includes a discharge platform, and a turret is connected between the discharge platform and the wrapping platform. The turret includes a main body and a clamping assembly. The main body is rotatably arranged and the rotation center line extends laterally. The clamping assembly is distributed circumferentially along the main body. An intermediate glue spraying assembly is provided circumferentially on the turret. The intermediate glue spraying assembly includes an intermediate glue spraying head, a backing plate and an air nozzle. The air nozzle faces the backing plate and the intermediate glue spraying head is laterally movable.

[0011] In this design, a backing plate is used to abut the long side, and a central spray nozzle sprays adhesive onto the bonding area of ​​the long side. The turret rotates, causing the long side to bend under the action of the backing plate. An air nozzle sprays air onto the backing plate, creating pressure on the long side, causing the long side to bend under tension.

[0012] Preferably, the clamp assembly includes a left clamp and a right clamp, each of which includes a top plate, a bottom plate, and a side plate, with gaps formed between the upper ends of the top plate and the side plate, and between the bottom plate and the lower ends of the side plate, for accommodating an ear.

[0013] In this design, the top plate, bottom plate, and side plates are fixed with folded ears.

[0014] Preferably, the discharge platform has a second opening for the second pusher to pass through and move longitudinally, and the main body includes a first mounting frame and a second mounting frame, with a pushing gap formed between the first mounting frame and the second mounting frame for the second pusher to pass through.

[0015] In this scheme, the second pusher passes through the pushing gap and pushes the material at the clamp assembly onto the discharge platform.

[0016] Preferably, the discharge platform is provided with a middle sealing mechanism and a side sealing mechanism in sequence. The middle sealing mechanism includes a second upper insert plate, a second side insert plate, and a second pressure roller. The second upper insert plate and the second pressure roller are sequentially arranged above the second side insert plate. Gap gaps for accommodating ears are provided between the upper end of the second upper insert plate and the second side insert plate, and between the discharge platform and the lower end of the second side insert plate. The side sealing mechanism includes a guide ear plate, a folded upper ear plate, a folded lower ear plate, a side glue spray head, and a pressing plate. An upper ear channel is formed between the plate and the upper ear plate, and a lower ear channel is formed between the upper ear plate and the lower ear plate. The upper ear channel and the lower ear channel are V-shaped and inclined relative to the material conveying direction. The upper ear of the outer packaging is guided into the upper ear channel along the guide ear edge of the guide ear plate. A guide ear channel communicating with the lower ear channel is formed between the lower end of the guide ear plate and the lower end of the upper ear plate and the discharge platform. The upper ear plate has a through hole in the middle for the side glue spray head to be exposed. The pressing plate is laterally movable.

[0017] In this scheme, under the push of the second pusher, the material goes through the folding and sealing in sequence. After the folding, the outer packaging paper comes into contact with the second pressure roller and is pressed against the surface of the soap, and the upper and lower layers are fully bonded together, and the crease line is shaped.

[0018] Preferably, the through hole is connected to the folded-down ear channel.

[0019] In this design, the adhesive sprayed on the bent upper ear section will not come into contact with the folded upper ear plate.

[0020] Preferably, the folded ear plate is equipped with a pressure strip.

[0021] In this solution, the pressure strip keeps the material stable during the side sealing process, preventing it from shifting and affecting the folding effect.

[0022] Preferably, the feeding end of the second upper insert plate is connected to a folding board, which is inclined.

[0023] 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.

[0024] The beneficial effects of this utility model are that the first and second pressure rollers are designed to press the outer packaging paper after the folding ears; the air nozzle sprays air onto the backing plate, creating pressure at the long side, causing the long side to bend under tension. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0043] See appendix Figure 1-13In this embodiment, a three-dimensional paper packaging machine for soap includes a first pusher head 1, a wrapping platform 2, and a discharge platform 21. The wrapping platform 2 has a first opening 3 for the first pusher head 1 to pass through and move longitudinally. Below the first opening 3, there is a support plate 16 for supporting the first pusher head 1. An installation shaft is provided between two sets of first chains. The first pusher head 1 is oscillatingly mounted on the installation shaft. The first pusher head 1 has notches 18 on both sides for the wrapping platform 2 to pass through. The first opening 3 is connected to a pusher head passage 19. The pusher head passage 19 is equipped with a top block 20, and the top block 20 drives the first pusher head 1 to oscillate.

[0044] A turret 22 connects the discharge platform 21 and the wrapping platform 2. The turret 22 includes a main body 23 and a clamping assembly 24. The main body 23 is rotatably mounted with its rotation center line extending laterally. The clamping assembly 24 is distributed circumferentially along the main body 23 and includes a left clamp 29 and a right clamp 30. Both the left clamp 29 and the right clamp 30 include a top plate 31, a bottom plate 32, and a side plate 33. The top plate 31 and the upper ends of the side plate 33 are connected by a turret 22. A gap is formed between the 2 and the lower end of the side plate 33 for accommodating the ear. The turret 22 is equipped with a middle adhesive spraying assembly 25 around its circumference. The discharge platform 21 is provided with a second opening 34 for the second pusher to pass through and move longitudinally. The main body 23 includes a first mounting frame 35 and a second mounting frame 36. A pushing gap is formed between the first mounting frame 35 and the second mounting frame 36 for the second pusher to pass through. The discharge platform 21 is provided with a middle sealing mechanism 37 and a side sealing mechanism 41 in sequence.

[0045] The paper-wrapping platform 2 is provided with a first paper-wrapping mechanism 4 and a first folding ear assembly 5 in a longitudinal direction. The first folding ear assembly 5 includes a first upper insert plate 6, a first side insert plate 7 and a first pressure roller 8. The first upper insert plate 6 and the first pressure roller 8 are arranged above the first side insert plate 7 in a sequential manner. There are gaps for accommodating the ear between the upper end of the first upper insert plate 6 and the first side insert plate 7 and between the paper-wrapping platform 2 and the lower end of the first side insert plate 7.

[0046] The intermediate glue spraying assembly 25 includes an intermediate glue spraying head 26, a backing plate 27, and an air nozzle 28. The air nozzle 28 faces the backing plate 27, and the intermediate glue spraying head 26 is laterally movable.

[0047] The intermediate sealing mechanism 37 includes a second upper insert plate 38, a second side insert plate 39, and a second pressure roller 40. The second upper insert plate 38 and the second pressure roller 40 are sequentially arranged above the second side insert plate 39. There are gaps for accommodating the ears between the upper ends of the second upper insert plate 38 and the second side insert plate 39, and between the discharge platform 21 and the lower end of the second side insert plate 39. The feeding end of the second upper insert plate 38 is connected to a folding paperboard 52, which is inclined.

[0048] The side sealing mechanism 41 includes a guide ear plate 42, an upper folding ear plate 43, a lower folding ear plate 44, a side glue spray head 45, and a pressing plate 46. An upper folding ear channel 47 is formed between the guide ear plate 42 and the upper folding ear plate 43, and a lower folding ear channel 48 is formed between the upper folding ear plate 43 and the lower folding ear plate 44. The upper folding ear channel 47 and the lower folding ear channel 48 are V-shaped and inclined relative to the material conveying direction. The upper ear of the outer packaging is guided into the upper folding ear channel 47 along the guide ear edge 50 of the guide ear plate 42. A guide ear channel 49 communicating with the lower folding ear channel 48 is formed between the lower end of the guide ear plate 42 and the lower end of the upper folding ear plate 43 and the discharge platform 21. The upper folding ear plate 43 is provided with a through hole 51 in the middle for the side glue spray head 45 to be exposed. The through hole 51 communicates with the lower folding ear channel 48. The upper folding ear plate 43 is equipped with a pressure box strip. The pressing plate 46 is laterally movable.

[0049] In this embodiment, the conveying direction is from front to back (longitudinal). The first chain drives the first pusher 1 to move longitudinally and pass through the first paper wrapping mechanism 4 and the first folding ear assembly 5 in sequence. The paper strip covers the four sides of the soap and defines them as sides A, B, C, and D. At the first paper wrapping mechanism 4, side B of the soap is covered by the paper strip and the end of the paper strip is pulled away from the first transverse opening 15, and part of side A presses down on the end of the paper strip to form a short side.

[0050] At the first folding ear assembly 5, the first upper insert plate 6 will fold the long side forward to cover the C surface to form a crease line. The first side insert plate 7 will bend the two sides of the B bread paper forward to form a corner of the ear for sealing. The first pressure roller 8 will press the long side along the outer contour of the soap to shape the crease line. The first side insert plate 7 can be extended to guide the pushing of the soap. At the first wrapping mechanism 4, the first side insert plate 7 is disconnected or a notch 18 is set.

[0051] The first pusher 1 pushes the soap into the turret 22 and into place. The top block 20 drives the first pusher 1 to swing. The first pusher 1 passes through the pusher passage 19 under the drive of the first chain. At this time, the first pusher 1 has both backward and downward displacement. The specific driving principle is that the first pusher 1 is set with a driving surface, and the top block 20 is in line contact with the driving surface, so that the first pusher 1 swings forward.

[0052] The clamping assembly 24 receives the soap pushed by the first pusher head 1. The gap of the clamping assembly 24 maintains the folded ear state of the paper packaging. The soap is conveyed longitudinally on both the discharge platform 21 and the wrapping platform 2. Therefore, the soap rotates 180 degrees under the drive of the turret 22 to complete the flipping. At the middle glue spraying assembly 25, the long side is attached to the backing plate 27, and the glue spraying position on the long side is exposed. After the middle glue spraying head 26 moves laterally into place, it sprays glue on the long side and then resets. The turret 22 continues to flip, and the lower end of the backing plate 27 bends the long side to cover the C-side and form a crease line. At the same time, the air nozzle 28 sprays glue onto the backing plate 27. Air is blown to apply pressure to the long side, causing it to bend as much as possible along the angle between surface C and surface A. After flipping, surface A of the soap faces upward, the short side is exposed, and surface D faces backward. The second pusher (not shown in the figure) pushes the soap from the clamp assembly 24 onto the discharge platform 21 through the pusher gap. The long side bends and covers surface A under the action of the front end of the second upper insert plate 38, forming a crease line. The side baffle will cause the two sides of the D-side wrapper to bend forward, forming another area on the side for sealing. After the second folding of the ear, the pressure roller presses surface A along the outer contour of the soap, shaping the crease line and making the short side and long side fit together.

[0053] At this point, the upper ear is defined as the upper ear and the lower ear as the lower ear. The upper ear enters the upper ear folding channel 47 along the ear guide plate 42 and the lower ear folding channel 47 along the lower edge of the ear guide plate 43. The upper ear folds down and exits the ear folding channel 47, reaching the middle of the ear guide plate 43. The side spray nozzle 45 sprays glue onto the upper ear at the glue-to-be-sprayed position. The lower ear enters the lower ear folding channel 48 through the ear guide channel 49. The lower ear folds up and exits the lower ear folding channel 48 along the upper edge of the ear folding channel 44. The pressing plate 46 moves laterally to make the upper and lower ears fit together.

[0054] The first chain and the second chain are both wound around the sprocket, and the motor drives the sprocket to rotate; the notch 18 cooperates with the paper wrapping platform 2 to limit the left and right displacement of the first push head 1, and the first push head 1 has an arc-shaped part corresponding to the support plate 16 to reduce friction.

[0055] The cutting assembly 14 includes a cutter and a cutter holder mounted on the cutter roller. The cutter and the cutter holder work together to cut the first paper strip to form a long side. The traction roller group 13 is equipped with an unwinding assembly. The paper wrapping mechanism as a whole is a mature technology.

[0056] The first longitudinal opening is narrower than the first transverse opening 15 and the second transverse opening 15 in the horizontal direction, so that the contact area between the paper wrapping platform 2 and the soap is large and it can stably support the soap.

[0057] The first pressure roller 8 and the air nozzle 28 are mounted on the same mounting base. A spring is also provided between the first pressure roller 8 and the mounting shaft, which provides high rigidity.

[0058] The upper ear channel 47 and the lower ear channel 48 form a channel with at least one section of the edge line being inclined, so that the ear gradually bends along the edge line during the conveying process; the through hole 51 is connected to the lower ear channel 48, so that the glue will not come into contact with the upper ear plate 43; the glue spray head is a mature technology.

[0059] In other embodiments, the lower ear can be folded down first, glue can be sprayed on, and then the upper ear can be folded up; the middle glue spray head 26 can also adopt other movement trajectories, as long as it can avoid the long side.

[0060] See appendix Figure 7 The paper wrapping platform 2 is equipped with a feeding mechanism 9 at its feeding end. The feeding mechanism 9 includes a feeding conveyor belt 10 and a feeding pusher 11. The feeding conveyor belt 10 is in the longitudinal direction. The feeding pusher 11, which moves laterally, is provided above the feeding conveyor belt 10. The paper wrapping platform 2 is equipped with a second paper wrapping mechanism 12. Both the first paper wrapping mechanism 4 and the second paper wrapping mechanism 12 include a traction roller group 13 and a cutting component 14. The traction roller group 13 and the cutting component 14 are arranged in sequence along the vertical direction. The traction roller group 13 pulls to form a paper strip. The first opening 3 extends to both sides with transverse openings 15 for the paper strip to pass through.

[0061] In this embodiment, the feeding conveyor belt 10 is connected to the soap production equipment. The feeding pusher 11 pushes the soap on the feeding conveyor belt 10 onto the wrapping platform 2. The first wrapping mechanism 4 and the second wrapping mechanism 12 wrap the soap with two layers of paper. The inner layer absorbs water and dries, and the outer layer forms the outer packaging. The inner layer of paper is narrower than the outer layer of paper. The feeding pusher 11 is set on the synchronous belt, and the zero point position of the synchronous belt is set for easy debugging. Specifically, a sensor is set to sense the position of the feeding pusher 11. After the synchronous belt drives the feeding pusher 11 to the position, the sensor sends a position signal to the controller. The controller stops the feeding motor based on the position signal. The interval between the feeding pushers 11 is large enough to accommodate soaps of different specifications. The first side plate 7 on one side can be extended to block the soap when the feeding pusher 11 is pushed to the position.

[0062] 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.
