The blowing pipeline 302 consists of a vertical pipeline 302a and a plurality of horizontal pipelines 302b. The vertical pipeline 302a and the plurality of horizontal pipelines 302b are respectively connected, and a plurality of rows of blowing holes 302c are evenly spaced on the horizontal pipeline 302b.

[0051] The end of the vertical pipe 302a is clamped in the U-shaped clamping groove 304 of the pulp barrel upper cover 303 and is detachably fixed on the pulp barrel upper cover 303; a float liquid level switch 305 is also provided in the pulp barrel body 301. The float liquid level switch 305 is mainly provided to facilitate the control of the liquid level in the barrel. In this patent, liquid level switches are provided on the raw pulp barrel, pulp storage barrel, and water pool barrel, which can facilitate the monitoring of the liquid level.

[0052] In this patent, a blowing pipe 302 is provided in the raw pulp barrel 3, and a blowing hole 302c is provided on the blowing pipe 302 for blowing and stirring the slurry in the raw pulp barrel 3, replacing the traditional stirring device, and the blowing pipe 302 is simple, compact and convenient. It is provided in the raw pulp barrel 3 and can be disassembled together with the raw pulp barrel 3, and the tank is changed, which is relatively convenient. The blowing pipe 302 is used to keep blowing the slurry, which can ensure that the paper pieces in the raw pulp barrel are uniform and will not settle in a certain place.

[0053] A blowing pipeline 302 is also provided inside the slurry storage tank 5, and the angle between each two adjacent rows of blowing holes 302c (because the blowing holes are relatively small, the blowing holes are partially enlarged in the figure for illustration, which is not the actual setting state) is 30°~45°.

[0058] In this patent, a liquid level sensor 501 is provided on the slurry storage tank 5. When the liquid level in the slurry storage tank reaches the warning line, the liquid level sensor 501 alarms and the slurry pump 7 stops pumping slurry. This patent arranges the slurry pumping pipeline and the water pumping pipeline reasonably, making the layout of the whole equipment more reasonable and neat.

[0059] It also includes a high-pressure gas tank 9 and a low-pressure gas tank 10. The high-pressure gas tank 9 is connected to the blowing pipeline 302 and is used to blow and stir the slurry in the raw pulp barrel 3; the pipeline of the slurry scooping device 4 is connected to the high-pressure gas tank 9 and the low-pressure gas tank 10 through a conversion joint, respectively, to provide working air pressure to the slurry scooping device 4.

[0060] In this patent, the high-pressure gas storage tank 9 is connected to the blowing pipeline 302 through a pipeline (the pipeline is not shown in the figure), which is used to provide air flow to the blowing pipeline 302 to stir the slurry and ensure the uniformity of the pulp in the raw pulp barrel 3 at all times to ensure the uniformity of the pulp.

[0061] The slurry scooping device 4 is connected to the high-pressure gas storage tank 9 and the low-pressure gas storage tank 10 respectively through a conversion joint (the conversion joint is commercially available and not shown in the figure) to provide working air pressure to the slurry scooping device 4. When in a positive pressure working state, a blowing force is provided to the slurry scooping device, and when in a negative pressure working state, a suction force is provided to the slurry scooping device.

[0062] The slurry scooping device 4 includes a slurry scooping module 11 and an upper die forming module 12, which are slidably arranged on a support frame 13, and the slurry scooping module 11 and the upper die forming module 12 are fixedly connected, the support frame 13 is fixedly arranged on the frame body 1, and a push-pull cylinder 14 is also arranged on the frame body 1, one end of the push-pull cylinder 14 is fixed on the frame body 1, and the movable end of the push-pull cylinder 14 is connected to the side of the slurry scooping module 11, and the push-pull cylinder 14 pushes the slurry scooping module 11 and the upper die forming module 12 to slide back and forth on the support frame 13. A plurality of buffers 17 are arranged on the frame body 1 to provide buffering for the slurry scooping device 4 to slide back and forth.

[0063] In this patent, the slurry scooping module 11 and the upper pressure mold forming module 12 are double-station linkage modules. The slurry scooping module is used to absorb the slurry and demould, and the upper pressure mold forming module and the lower mold forming module complete heating molding, shaping and other actions together.

[0064] In this patent, the pulp scooping device 4 is connected to the high-pressure gas tank 9 and the low-pressure gas tank 10 through a conversion joint, providing suction and blowing force to the pulp scooping module, the suction force is used to suck the pulp, and the blowing force is used to demold the pulp scooping module. At the same time, the upper die molding module is connected to the high-pressure gas tank and the low-pressure gas tank through a conversion joint to achieve the function of transportation, that is, sucking the paper mold product and then putting down the paper film product.

[0065] Preferably, the pulping module 11 includes a downward pressure cylinder 1101, a push-pull plate 1102 and a lower suction plate 1103, the downward pressure cylinder 1101 is fixed to the frame body 1 through an upper mounting plate 1104, and the movable end of the downward pressure cylinder 1101 is fixed to the push-pull plate 1102, the push-pull plate 1102 is fixedly connected to the top of the side plate 1105, and the bottom of the side plate 1105 is fixedly connected or movably connected to the lower suction plate 1103.

[0066] In this patent, there are two ways of connecting the bottom of the side panel 1105 with the lower suction plate 1103, namely a fixed connection and a movable connection. When it is a fixed connection, there is no need to filter the water. When it is a movable connection, the lower suction plate can be tilted to filter the water, which is convenient for subsequent mold closing.

[0067] When the bottom of the side plate 1105 is movably connected to the lower suction plate 1103 , one end of the side plate 1105 is movably connected to the lower suction plate through a bearing, and the other end is a free end, and the angle of the lower suction plate 1103 is tilted by turning the cylinder 1106 .

[0069] In this patent, the inclination angle of the lower suction plate 1103 can be set according to actual production needs. When the lower suction plate is tilted, the water in the upper template can be filtered out, which is energy-saving and environmentally friendly. The inclination angle can be set according to actual use needs. This patent does not limit the inclination angle of the lower suction plate.

[0070] The sides of the frame body 1 are detachably provided with blocking crossbeams 15. When the blocking crossbeams 15 are removed, the raw pulp barrel 3 and the water pool barrel 6 can be drawn out from the frame body for replacement.

[0071] In traditional forming machines, the pulp barrel cannot be disassembled. When the pulp color changes, it takes a lot of effort and time to clean it, wasting manpower and material resources. In addition, the pulper is operated as an independent device. It is very troublesome to pump the pulp into the pulp barrel after the pulp is crushed. The coordination of the equipment is poor. This patent highly concentrates the equipment and innovates the structure, which not only reduces the space occupied by the equipment, but also has high coordination performance.

[0072] like Figure 11-13 , which is a schematic diagram of the structure of a pulper 2 of the present invention, comprising a paper shredding barrel body 201, wherein the paper shredding barrel body 201 is a barrel body with a half-open cover, and a plurality of locking blocks 202 are arranged at the bottom of the paper shredding barrel body 201, and the paper shredding barrel body 201 is locked on the frame body 1 through the locking blocks 202, and a motor reducer module 203 is arranged above the paper shredding barrel body 201, and the motor reducer module 203 is arranged on the frame body 1 through a mounting frame 204;

[0074] The bottom of the shredding barrel body 201 is conical, and a raw pulp valve 207 is arranged at the bottom thereof. A filter plate 208 is arranged at the bottom of the inner cavity of the shredding barrel body 201 . The water pumping pipe 801 is arranged on the shredding barrel body 201 to supply water thereto.

[0075] Embodiment 2

[0076] In this patent, the process flow of the slurry scooping device 4 is as follows:

[0077] (1) The push-pull cylinder 14 moves the slurry scooping module 11 to the top of the slurry storage tank 5;

[0078] (2) The downward pressure cylinder 1101 pushes the push-pull plate 1102 to move downward;

[0079] (3) When the push-pull plate 1102 drops below the liquid level of the slurry storage tank 5, the upper template 1107 located under the lower suction plate 1103 absorbs the slurry, and the power for the upper template 1107 to absorb the slurry is provided by the low-pressure gas storage tank 10;

[0080] (4) After the slurry is sucked, the lower pressure cylinder 1101 contracts, driving the upper template 1107 to return to its original position;

[0081] (5) Then the push-pull cylinder 14 pushes the pulp scooping device 4 to continue moving forward;

[0082] (6) When the slurry scooping module 11 moves to the position above the lower mold forming module 18, it stops moving;

[0083] (7) The downward pressure cylinder 1101 pushes the push-pull plate 1102 to move downward. When it moves to the lower mold-clamping molding module 18, the high-pressure gas storage tank 9 blows air to the upper mold plate 1107 to demould, and the upper mold plate (the upper mold plate is a schematic diagram, and the specific mold plate structure is determined by the structure of the specific product) 1107 falls on the lower mold-clamping molding module 18;

[0084] (8) The push-pull cylinder 14 contracts, and the slurry scooping module 11 moves back. At this time, the upper pressing mold forming module 12 happens to be above the station of the lower closing mold forming module 18;

[0085] (9) The upper die forming module 12 moves downward under the drive of the hydraulic booster cylinder 19 to shape the paper-plastic product. After the shaping is completed, it returns to its original position and enters the next cycle.

[0086] In this patent, the pipeline of the pulp scooping device is connected to the high-pressure gas tank and the low-pressure gas tank through a conversion joint, providing suction and blowing force to the pulp scooping module, the suction force is used to suck the pulp, and the blowing force is used to demold the pulp scooping module. At the same time, the upper pressure mold forming module is connected to the high-pressure gas tank and the low-pressure gas tank through a conversion joint to achieve the function of transportation, that is, sucking the paper mold product and then putting down the paper film product.

[0087] In paper-molding machines, the replacement of the pulp pool is a difficult problem currently faced, because the pulp pool is large and difficult to clean. At the same time, there will be some liquid residue and color residue in the pulp pool. If the color is not cleaned, it will directly affect the appearance quality of the product. The original pulp pool of this patent is designed to be easy to disassemble, which easily solves the above problems. An electric control box 16 is arranged next to the water tank 6, and the overall structure is compact, which greatly reduces the size of the device.

[0088] The described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
