Description

Multifunctional suction equipment and its usage Technical Field

[0001] This application relates to the field of paper-plastic parts manufacturing technology, and more specifically, to a multifunctional suction device and its usage. Background Technology

[0002] The paper and plastic industry is developing rapidly, with production capacity and output constantly increasing. With the advancement of the "plastic ban" and the improvement of environmental awareness, the market space for paper and plastic parts is huge. Due to their environmental characteristics, such as recyclability and biodegradability, paper and plastic products are gradually replacing traditional plastic products.

[0003] Paper-plastic parts are mainly made from raw materials such as waste paper and plant fibers. After a series of processes such as crushing and grinding, the pulp is made into slurry. Through the slurry suction process, the fibers in the slurry are deposited on the forming screen. Then, the pulp is filtered and dehydrated to make wet preforms. Excess water is removed through processes such as pressing and drying. Finally, the preforms are shaped, inspected and packaged.

[0004] In related technologies, pulp suction equipment typically includes an upper mold and a lower mold. The upper mold is a wet preform transfer and extrusion mold, or a hot pressing mold. The lower mold is usually a pulp suction mold. The lower mold can move up and down or rotate independently. During pulp suction, the lower mold moves downward or rotates to sink into the pulp tank for pulp suction, and then moves upward or rotates to perform vacuum suction and dewatering, or moves upward to close with the upper mold to squeeze and absorb the wet pulp preform or perform hot pressing and dewatering, etc. In these devices, the upper mold is usually fixed or can be moved horizontally independently. Some equipment used to make paper-plastic bottle-shaped containers designs the upper and lower molds to be able to move synchronously.

[0005] In actual operation, it was found that although these devices can all achieve slurry suction, some paper-plastic bottle-shaped containers can only be fixed horizontally by the upper and lower molds and can only be suctioned through the slurry inlet side; and the vacuum and drainage holes of the mold fixing plate can only perform suction and drainage with a single strength and pressure; moreover, suctioning through the slurry inlet alone will cause the problem of excessive water flow in some areas, which will lead to uneven slurry suction and thinning of the slurry in some parts of the product. Each device can only manufacture a single type of product, and its application has certain limitations.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] The multifunctional suction device 1000 according to an embodiment of this application is described below with reference to Figures 1-9.

[0046] As shown in Figures 1-9, a multifunctional suction device 1000 according to an embodiment of this application includes a base 100 and a mold mechanism 200. The mold mechanism 200 is disposed on the base 100 and includes a rotary drive device 40 and a mold device 30. The mold device 30 includes a first mold 31 and a second mold 32.

[0047] The mold device 30 has a first state in which the first mold 31 and the second mold 32 cooperate with each other and can form the required cavity (not shown in the figure) after cooperation. The cavity has one or more slurry inlets 301 through which slurry can enter the cavity.

[0048] The rotary drive device 40 can at least drive the mold device 30 to rotate in the first state. That is, after the two molds are engaged, the rotary drive device 40 can drive the two molds to rotate simultaneously. Thus, when the two molds are simultaneously sucking or injecting slurry, the position and angle of the slurry inlet 301 can be adjusted by driving the rotation of the rotary drive device 40. For example, the mold device 30 can be tilted or side-entered at various angles, such as horizontal, with the slurry inlet 301 on top or bottom, so that the slurry injection is more uniform and the slurry can be locally reduced or increased. After the slurry injection is completed, the rotary drive device 40 can also drive the two molds to rotate, so that the slurry in the cavity is more uniform and can be locally thickened or thinned. At the same time, drainage can be more controllable, improving the molding effect of the wet preform and increasing production capacity. In addition, when manufacturing some products, such as bottle-shaped containers, rotating the mold device 30 is also beneficial for the demolding of the wet preform.

[0049] According to the embodiments of this application, the multifunctional slurry suction device 1000, by setting a rotary drive device 40, drives the mold device 30 in the first state to rotate, thereby adjusting the position of the two molds, and thus adjusting the position and angle of the slurry inlet 301, making the slurry feeding more uniform and controllable, making the slurry arrangement in the cavity more controllable, improving the molding effect of the wet preform, meeting the manufacturing needs of different paper and plastic products, and solving the problems of single product manufacturing and limited application of traditional slurry suction equipment.

[0050] In some embodiments, the mold device 30 has a second state in which the first mold 31 and the second mold 32 are separated. The rotation drive device 40 can drive the first mold 31 to rotate, drive the second mold 32 to rotate, or drive the first mold 31 and the second mold 32 to rotate simultaneously.

[0051] Traditional slurry suction equipment cannot address the issues of cavity division, time-based, and intensity-based vacuum, air pressure, and drainage for cavity-divided molds. However, the slurry suction equipment of this application allows for independent slurry intake and drainage of the first mold 31 and the second mold 32 when they are separated. The rotary drive device 40 drives the first mold 31 and / or the second mold 32 to rotate, thereby enabling slurry suction of a single mold. Simultaneously, it can perform cavity division, time-based, and intensity-based vacuum, air pressure, and drainage on a single mold. This also makes the slurry intake of the mold more uniform, the drainage more controllable, and improves the forming effect of the wet blank on the mold, meeting the manufacturing needs of different products.

[0052] As shown in Figure 6, in some examples, the first mold 31 is located on one side of the second mold 32. Both the first mold 31 and the second mold 32 are connected to the rotary drive device 40. When the first mold 31 and the second mold 32 are engaged, or when the first mold 31 and the second mold 32 are separated, the rotary drive device 40 can drive the two molds to rotate simultaneously, so that the mold device 30 in different states can achieve better slurry inlet and outlet.

[0053] In other words, the mold device 30 has two states, which can correspond to the mold closed state and the mold open state. In any state, the mold can independently suck slurry, drain water, etc. For example, the two molds can be vacuumed and sucked slurry independently, compressed air supplied independently, and drained independently when the two molds are separated. They can also suck slurry and drain water from a single mold. They can also suck slurry simultaneously or at different times when the two molds are in the same state. They can also switch states multiple times and suck slurry and drain water repeatedly at different times in different states. They can also squeeze and dehydrate when the two molds are in the same state.

[0054] In other examples, the first mold 31 is disposed on one side of the second mold 32, and the rotary drive device 40 includes two, one for driving the first mold 31 and the other for driving the second mold 32. Thus, when the first mold 31 and the second mold 32 are engaged, the two rotary drive devices 40 can simultaneously drive the corresponding molds to rotate. When the first mold 31 and the second mold 32 are separated, each rotary drive device 40 can simultaneously drive the corresponding mold to rotate, or one rotary drive device 40 can drive the corresponding mold to rotate while the other rotary drive device 40 does not work and the other mold remains stationary.

[0055] In some other examples, the first mold 31 is disposed on one side of the second mold 32, and the rotary drive device 40 is connected to a mold to drive the mold to rotate. When the first mold 31 and the second mold 32 are engaged, the first mold 31 and the second mold 32 are connected to each other, and the rotary drive device 40 can drive the two molds to rotate simultaneously. When the first mold 31 and the second mold 32 are separated, the rotary drive device 40 can drive the corresponding mold to rotate, while the other mold remains stationary.

[0056] As shown in Figure 6, in some embodiments, the mold device 30 further includes a first fixing plate 33 and a second fixing plate 34. The first mold 31 and the second mold 32 are installed between the first fixing plate 33 and the second fixing plate 34. The first mold 31 is detachably connected to the first fixing plate 33, and the second mold 32 is detachably connected to the second fixing plate 34. The rotary drive device 40 can be connected to the fixing plate to drive the mold to rotate by driving the fixing plate to rotate. This facilitates the disassembly of the first mold 31 and the second mold 32, making disassembly and maintenance easier, and facilitating the replacement of molds of different models or sizes. This expands the types of products that the suction equipment can manufacture, allowing the mold device 30 to be used as an extrusion molding mold, as a paper-plastic bottle container, or as a thermoforming mold, etc., to meet different manufacturing needs.

[0057] As shown in Figure 6, in some embodiments, the mold device 30 further includes an opening and closing drive device 35 and a mounting member 36. The opening and closing drive device 35 is disposed on the mounting member 36, and the mounting member 36 is fixedly connected to the first fixed plate 33. The output end of the opening and closing drive device 35 is fixedly connected to the second fixed plate 34. Of course, the mounting member 36 can also be fixedly connected to the second fixed plate 34, and the output end of the opening and closing drive device 35 can be fixedly connected to the first fixed plate 33. Thus, the opening and closing drive device 35 drives one fixed plate to move relative to the other fixed plate, thereby causing the mold on the fixed plate to move, so that the mold device 30 switches between the first state and the second state.

[0058] As shown in Figure 6, the mounting component 36 includes multiple mounting posts and a mounting plate. One end of the multiple mounting posts is connected to the second fixing plate 34. The multiple mounting posts pass through mounting holes on the first fixing plate 33. The mounting plate is connected to the other end of the multiple mounting posts. The opening and closing drive device 35 is fixed on the mounting plate. The output end of the opening and closing drive device 35 is fixedly connected to the first fixing plate 33 to drive the first fixing plate 33 and the first mold 31 to move, so that the first mold 31 and the second mold 32 can be engaged or disengaged.

[0059] Of course, the mold device 30 can also be connected to a multi-axis robotic arm. The end of the robotic arm is loaded with an opening and closing mechanism such as a motor or cylinder. The opening and closing mechanism is connected to the first fixed plate 33 or the second fixed plate 34. The opening and closing mechanism can also be connected to the first mold 31 or the second mold 32. The connection can be a direct connection or a connection through locking, bolts, fixing pins, etc. Then, the state of the mold device 30 is switched by the up and down movement of the robotic arm, the rotation of the end shaft, and the opening and closing of the opening and closing mechanism.

[0060] As shown in Figure 6, in some embodiments, the first fixing plate 33 and the second fixing plate 34 are respectively provided with a plurality of openings 331. At least a portion of the plurality of openings 331 are adapted to communicate with the cavity to form a positive or negative pressure in the cavity. That is, an external air source can be connected through the openings 331 to form a certain pressure in the cavity, thereby allowing gas and / or liquid to flow out or enter the cavity.

[0061] In some more specific embodiments, at least a portion of the multiple openings 331 are connected to the cavity, creating a negative pressure inside the cavity. This allows for air extraction and water filtration inside the cavity, thereby drawing out liquids and gases through the fine mesh inside the cavity, leaving the slurry inside the cavity to obtain a wet blank. In other more specific embodiments, at least a portion of the multiple openings 331 are connected to the cavity, creating a positive pressure inside the cavity. This allows for air intake to break the vacuum, facilitating the smooth demolding of the formed wet blank and preventing it from sticking to the mold. Furthermore, in some applications that run parallel to or intersperse with the aforementioned embodiments, it is necessary to perform intermittent air extraction and intake within the cavity, i.e., extracting air for a certain period followed by air intake for a certain period, to make the wet blank more dense and delicate.

[0062] The first fixing plate 33 has multiple openings 331, and the second fixing plate 34 has multiple openings 331. The multiple openings 331 can be arranged in an array. According to manufacturing requirements, the first mold 31 and the second mold 32 are installed between the first fixing plate 33 and the second fixing plate 34. According to the mold and the hole positions covered by the mold cavity, the pipes are connected to the required openings 331. Different pipes can be equipped with independent control air valves. Other openings 331 can be sealed with screw holes or sealing plugs. When suctioning the slurry, if a certain cavity needs to be suctioned independently, the valves of other air passages are closed, and the valves of the corresponding holes of a certain cavity are opened or closed at regular intervals to provide positive and negative pressure.

[0063] This allows for the use of molds of different sizes and types to control the vacuum, air pressure, and drainage of the molds by cavity, time, and intensity, thereby enabling the simultaneous production of different processes and types of products.

[0064] As shown in Figure 5, in some embodiments, the multifunctional suction device 1000 further includes at least one fixing pipe 51, which is located on one side of the mold device 30 and has an inlet and an outlet.

[0065] It should be noted that the fixing tube 51 can be fixed on the mold device 30 or installed on other structures. The fixing tube 51 can be located on one side of the mold device 30, so that it can extend into the cavity of the mold device 30 through the slurry inlet 301 of the mold device 30.

[0066] In some examples, the inlet of the fixed tube 51 can be connected to a slurry tube, and the portion of the fixed tube 51 with an outlet can be moved into the cavity to allow the slurry to flow into the cavity. For example, by inserting the fixed tube 51 into the cavity, pressure is applied, quantitative slurry is injected, and slurry is replenished, thereby improving the molding effect of the wet preform.

[0067] When the slurry pipe is connected for slurry injection, the mold device 30 can be in the first state, and the rotary drive device 40 can drive the mold device 30 to rotate so that the slurry inlet 301 faces a specific position, such as the upper part. At this time, the slurry is replenished in the cavity through the fixed pipe 51, and the slurry in the cavity can be made uniform by blowing air. The slurry inlet 301 can also face the side. At this time, the pressure in the cavity can be controlled to make different positions of the cavity suck slurry, meet the molding requirements of different wet blanks, and improve the molding effect of the wet blanks. Of course, the mold device 30 can also be switched to the second state.

[0068] In related technologies, when the molded product is a paper bottle container with an integrated inner and outer structure, existing equipment cannot perform pre-shaping and dewatering through upper and lower die extrusion; it can only perform slurry suction. However, in some other examples of this application, an elastic airbag is provided outside the fixed tube 51, covering the outlet, and at least a portion of the elastic airbag can extend into the mold cavity. The elastic airbag extending into the mold cavity can be inflated to form a specific shape, thereby squeezing the wet preform within the mold cavity to dewater or pre-shape it. The elastic airbag can be made of silicone, rubber, or other materials.

[0069] In other words, the multi-functional slurry suction equipment 1000 is equipped with a fixed pipe 51. This fixed pipe 51 can be a multi-purpose pipe. For example, when making paper-plastic bottle-shaped containers, an elastic airbag can be installed on the fixed pipe 51. By drawing a vacuum, the elastic airbag is compressed. The fixed pipe 51 is moved to insert the elastic airbag into the bottle-shaped container. Then, the elastic airbag is inflated. Through the combined pressure of the mold and the elastic airbag, the wet preform of the bottle-shaped container is squeezed to achieve dehydration, pre-shaping, etc. Alternatively, the fixed pipe 51 can be connected to the slurry pipe for replenishing slurry. By inserting the fixed pipe 51 into the mold, pressure is applied and slurry is replenished in a quantitative manner, thereby avoiding local thinning or collapse due to water flow impact and achieving a uniform wall thickness of the wet preform.

[0070] As shown in Figures 5 and 8, in some embodiments, the multifunctional suction device 1000 further includes a telescopic drive motor 5241 and a connecting seat 53. The telescopic drive motor 5241 is fixed on the mold device 30, and a plurality of fixed tubes 51 are installed on the connecting seat 53. The telescopic drive motor 5241 is connected to the connecting seat 53 to drive the plurality of fixed tubes 51 to move. The plurality of fixed tubes 51 are arranged at intervals along the extension direction of the connecting seat 53. The inlet of each fixed tube 51 is located on one side of the connecting seat 53, and the outlet of each fixed tube 51 is located on the other side of the connecting seat 53.

[0071] It should be noted that the multiple fixed pipes 51 here can be connected to the slurry pipe at the same time, or they can be installed with elastic airbags at the same time, or some can be connected to the slurry pipe and some can be installed with elastic airbags, in order to meet different manufacturing needs.

[0072] In some specific examples, the telescopic drive motor 5241 is fixed to the bottom of the second fixed plate 34, and the output end of the telescopic drive motor 5241 extends to the slurry inlet side of the mold device 30. Multiple fixed pipes 51 are connected to the connecting seat 53. The inlet of the fixed pipe 51 has a valve and is located on the slurry inlet 301 side of the mold device 30. The telescopic drive motor 5241 is a linear drive motor 41, which can drive the connecting seat 53 to move along a straight line. The telescopic drive motor 5241 can be connected to an external control system. The motor's action can be controlled by the program of the control system. At the same time, the valve can be opened or closed to perform slurry injection or air blowing and suction.

[0073] As shown in Figure 9, in some embodiments, the base 100 includes a base body 10 and a lifting mechanism 20. The base body 10 is provided with a slurry pool 11, and the lifting mechanism 20 is provided on the base body 10. The lifting mechanism 20 includes a lifting drive device 21 and a first crossbeam 22. The first crossbeam 22 is connected to one of the slurry pool 11 and the mold mechanism 200. The lifting drive device 21 is used to drive the first crossbeam 22 to move up and down, so that the slurry pool 11 and the mold mechanism 200 can move relative to each other, thereby allowing the first mold 31 and / or the second mold 32 to enter the slurry pool 11 for slurry suction, or to remove the first mold 31 and / or the second mold 32 from the slurry pool 11.

[0074] The slurry tank 11 can be made of sheet metal or stainless steel to improve its stability. The slurry tank 11 can also be equipped with an overflow trough, and the slurry tank 11 is also equipped with pipes such as a drain pipe, a vacuum pipe, and a waste liquid discharge pipe.

[0075] As shown in Figures 2 and 4, in some embodiments, the slurry pool 11 is fixed on the base 10, the mold device 30 is disposed between the first crossbeam 22 and the slurry pool 11, and the mold mechanism 200 includes a mounting bracket 60. The mold device 30 is rotatably disposed on the mounting bracket 60, and the mounting bracket 60 is fixedly connected to the first crossbeam 22. Thus, the lifting drive device 21 can drive the first crossbeam 22 to rise and fall, thereby driving the mounting bracket 60 to rise and fall. When the mounting bracket 60 rises and falls, the mold device 30 can move relative to the slurry pool 11, so that the mold can be inserted into or removed from the slurry pool 11.

[0076] It should be noted that when the mold device 30 extends into the slurry pool 11, the rotary drive device 40 can drive the mold device 30 to rotate within the slurry pool 11, or it can drive the mold device 30 to rotate at a specific angle before extending into the slurry pool 11.

[0077] As shown in Figure 9, in some embodiments, the lifting drive device 21 includes a lifting motor 211 and a lead screw 212. The first crossbeam 22 has a sliding block, which is threadedly engaged with the lead screw 212. The lifting motor 211 is connected to the lead screw 212 and is used to drive the lead screw 212 to rotate, so that the first crossbeam 22 moves along the axial direction of the lead screw 212. The lifting motor 211 can be set at one end of the lead screw 212, thereby directly driving the lead screw 212 to rotate. Alternatively, the lifting motor 211 can be set on one side of the lead screw 212 and can drive the lead screw 212 to rotate through a transmission structure, such as through a turbine structure transmission.

[0078] As shown in Figure 9, the base 10 is provided with four columns 12. The first crossbeam 22 is slidably engaged with the four columns 12, thereby improving the stability of the first crossbeam 22 during movement. In addition, a second crossbeam 13 can be connected to the four columns 12. The second crossbeam 13 is parallel to the first crossbeam 22 and is located above the first crossbeam 22, thereby improving the stability of the four columns 12.

[0079] As shown in Figures 5-7, in some embodiments, the mold mechanism 200 further includes: a mounting bracket 60, which is mounted on the base 100. The mounting bracket 60 has two cantilever arms 61 arranged opposite to each other. Each cantilever arm 61 is provided with a rotatable rotating shaft 62. The mold device 30 is located between the two cantilever arms 61, and both sides of the mold device 30 (the left and right sides as shown in Figure 5) are connected to the two rotating shafts 62. The rotation drive device 40 includes at least one drive motor 41, which can drive the two rotating shafts 62 to rotate, thereby driving the mold device 30 to rotate.

[0080] As shown in Figure 7, in some embodiments, the rotary drive device 40 includes a drive motor 41 and two transmission components 42. The drive motor 41 is mounted on the mounting bracket 60, and the two transmission components 42 are symmetrically arranged on both sides of the drive motor 41. Each transmission component 42 is connected to the drive motor 41, and the two transmission components 42 are correspondingly engaged with two rotating shafts 62. This allows the drive motor 41 to drive the two rotating shafts 62 to rotate simultaneously, making the rotation of the mold device 30 more stable and facilitating the control of the rotation of the mold device 30.

[0081] Of course, the rotary drive device 40 may also include two drive motors 41, which drive the two sides of the mold device 30 respectively, or one drive motor 41 drives the mold device 30 to rotate, and the other drive motor 41 serves as a backup motor.

[0082] As shown in Figure 7, in some embodiments, the transmission assembly 42 includes a drive sprocket 421 and a driven sprocket 422 on the outer periphery of the rotating shaft 62. The drive sprocket 421 and the driven sprocket 422 are connected by a chain. The drive motor 41 drives the drive sprocket 421 to rotate, thereby driving the chain to move. The driven sprocket 422 rotates accordingly, causing the rotating shaft 62 to rotate, thereby driving the rotation of the mold device 30.

[0083] In other embodiments, the transmission assembly 42 includes transmission teeth, and the outer periphery of the rotating shaft 62 is provided with mating teeth. The transmission teeth mesh with the mating teeth, and the drive motor 41 drives the transmission teeth to rotate, thereby enabling the drive motor 41 to drive the rotating shaft 62 to rotate, thereby realizing the drive of the mold device 30 to rotate.

[0084] As shown in Figure 5, in some embodiments, the multifunctional suction device 1000 further includes a rinsing mechanism 70, which is mounted on the base 100 or the mold mechanism 200. The rinsing mechanism 70 includes at least one spray pipe. As shown in Figure 5, the rinsing mechanism 70 is mounted on the mounting bracket 60. Spray pipes are respectively provided on opposite sides of the mounting bracket 60 (the front and rear sides as shown in Figure 5). Multiple spray pipes are provided on the cantilever 61 of the mounting bracket 60. The spray pipes are suitable for spraying water onto the mold device 30. For example, after the mold device 30 has completed one or more molding processes, the mold device 30 is placed in a second state, and the first mold 31 and the second mold 32 are sprayed through the spray pipes to complete the cleaning operation, which facilitates the subsequent use of the mold.

[0085] The above structural arrangement makes the entire multi-functional slurry suction equipment 1000 compact, while also enabling the lifting and rotation of the mold device 30, making the slurry feeding more uniform and controllable, making the slurry distribution in the cavity more controllable, improving the molding effect of the wet preform, and meeting the manufacturing needs of different paper-plastic products.

[0090] The multifunctional suction device according to the embodiments of this application also includes the following usage methods:

[0091] The mold assembly switches to the second state, and the first mold separates from the second mold;

At this time, slurry is injected into the cavity through the fixed pipe, and the slurry in the cavity can be made uniform by blowing air. The slurry inlet can also face the side. At this time, the pressure in the cavity can be controlled to make different positions of the cavity suck up slurry, meet the molding requirements of different wet blanks, and improve the molding effect of wet blanks.

[0099] Furthermore, when the inlet of the fixed pipe is connected to the outlet of the slurry pipe, the slurry pipe is connected to the metering equipment, which can control the amount of slurry introduced into the mold cavity.

[0100] Therefore, under the control of the metering equipment, the dosage of slurry entering the mold cavity is controlled, realizing the quantitative slurry feeding of the multifunctional slurry suction equipment.

[0103] The mold device in the first state is driven to rotate;

[0104] The inlet of the fixed tube is connected to the air pump tube. An elastic air bladder is installed outside the fixed tube.

[0105] Therefore, when the mold device is in the first state, the fixed tube can be connected to the air pump tube, and an elastic air bladder can be installed on the fixed tube. The elastic air bladder is compressed by drawing a vacuum, the fixed tube is moved to insert the elastic air bladder into the bottle-shaped container, and then the elastic air bladder is inflated. Through the combined pressure of the mold and the elastic air bladder, the wet preform of the bottle-shaped container is squeezed to achieve dehydration, pre-shaping, etc.

At this time, slurry is injected into the cavity through the fixed pipe, and the slurry in the cavity can be made uniform by blowing air. The slurry inlet can also face the side. At this time, the pressure in the cavity can be controlled to make different positions of the cavity suck up slurry, meet the molding requirements of different wet blanks, and improve the molding effect of wet blanks.

[0111] Furthermore, when the inlet of the fixed pipe is connected to the outlet of the slurry pipe, the slurry pipe is connected to the metering equipment, which can control the amount of slurry introduced into the mold cavity.

[0112] Therefore, under the control of the metering equipment, the dosage of slurry entering the mold cavity is controlled, realizing the quantitative slurry feeding of the multifunctional slurry suction equipment.

[0116] The inlet of the fixed tube is connected to the air pump tube. An elastic air bladder is installed outside the fixed tube. At least a part of the elastic air bladder extends into the mold cavity. Air is blown into the fixed tube through the air pump tube, causing the elastic air bladder to expand and shape the wet preform in the mold cavity.

[0117] Therefore, when the mold device is in the second state, the fixed tube can be connected to the air pump tube, and an elastic air bladder can be installed on the fixed tube. The elastic air bladder is compressed by drawing a vacuum, and the fixed tube is moved to insert the elastic air bladder into the bottle-shaped container. The elastic air bladder is then inflated. Through the combined pressure of the mold and the elastic air bladder, the wet preform of the bottle-shaped container is squeezed to achieve dehydration, pre-shaping, etc.

[0121] The openings on the first and second fixing plates are aligned with the air pipes for installation.

[0122] The lifting motor and drive motor start, controlling the mold device to descend and rotate to the set required position;

[0123] After the mold device descends to the set position, it sinks into the slurry tank and starts the vacuum operation to suck up the slurry.
