Description

Blowing and sucking integrated desktop-level plastic sucking machine

Priority application

The present application claims priority to chinese patent application No. CN2023108972890, entitled blow-suction integrated table top vacuum cleaner, filed in 7 months 20 of 2023, which is incorporated by reference in its entirety.

Technical Field

The utility model relates to the technical field of desktop-level plastic uptake, in particular to a blowing-sucking integrated desktop-level plastic uptake machine.

Background

The desktop-level Vacuum molding machine is a small Vacuum molding machine (Vacuum Former) suitable for manual operation,

it can be used for preparing various plastic products, such as chocolate boxes, plastic outer packages, artificial limbs and the like. The conventional table-top plastic suction machine generally heats a plastic sheet to a variable shape state, then moves the plastic sheet above a mold, and sucks air through an air suction pump so as to enable the plastic sheet to be attached to the mold for molding.

See, for example, patent application CN202121464860.2, which discloses a tabletop-level vacuum forming machine. The plastic uptake machine firstly heats the plastic sheet through the nanometer infrared electrothermal plate, and then descends the moving platform in a manual rotation mode after the heating is finished, so as to descend the plastic packaging material to the mould, and then carries out plastic uptake molding. For another example, see patent application CN202121349674, which discloses a tabletop vacuum reverse suction forming suction molding machine, which comprises a frame, a suction mold placing table, a control module, and an electric heating device and a vacuum pumping device electrically connected with the control module. The plastic sucking machine is also operated manually, and the heated plastic sheet is moved downwards to be close to the mold, and then the plastic sheet is sucked by a vacuum device to be attached to the outer surface of the mold under the air pressure for cooling and molding.

On the one hand, the prior tabletop-level plastic uptake machine has relatively limited success rate or molding quality of sheet material, and particularly when the prior tabletop-level plastic uptake machine is applied to a die with a complicated external structure, the molding success rate or quality of the prior tabletop-level plastic uptake machine can be obviously reduced. For example, during the deformation of the plastic bonding mold, breakage is likely to occur, resulting in processing failure. On the other hand, the working performance of the desktop-level plastic sucking machine is relatively low (such as low heating efficiency and poor sealing performance).

The desktop-level plastic sucking machine can be widely applied to industrialized or non-industrialized preparation and utilization. For example, for 3D printing or DIY lovers, desktop grade suction molding machines are typically selected to make various types of small products or product accessories in a home environment, such as masks, toy vehicles, building models, mountain models, automotive accessories, and the like. However, current tabletop-grade vacuum cleaners have a low success rate of product preparation or product quality deviation on the one hand, and a relatively high application cost (e.g., relatively high power consumption) for household scenes on the other hand. In order to better meet the application requirements of the technical field of desktop-level plastic suction, the utility model provides the desktop-level plastic suction machine with better molding efficiency and better molding quality.

Example 1

As shown in fig. 1-16, the present utility model provides a tabletop-level plastic uptake machine with blowing and sucking integrated,

comprising the following steps:

a case 1 and a cover 2 matched with the case; wherein,

a mounting component 10 is arranged at the opening of the box body and is used for mounting the target material 3;

a lifting space I and an equipment space II are sequentially arranged in the box body 1; wherein, the lifting space I is internally provided with a lifting platform 12 for bearing a mould (such as a building model, an automobile model and the like and at least one moving guide component 11 for the lifting platform to move up and down in the lifting space; a positive pressure component 13, a negative pressure component 14 and a power component 15 are arranged in the equipment space;

the positive pressure component is used for pumping positive pressure air (namely blowing) into the box body after the target material is heated to a corresponding state, so that the target material is uniformly deformed under the action of the corresponding positive pressure (wherein, uniform deformation can refer to a state that the deformation degree or the stress of the target material at each site are equal or approximately equal), and the target material is converted into a bulge state; and the positive pressure assembly comprises: a positive pressure interface 131, and an air pump (such as an air pump) connected with the positive pressure interface 131;

The negative pressure component is used for making the upper surface of the lifting platform 12 and the lower surface of the target material 3 mutually contact and enclose a sealed space IV by sucking air when the target material approaches or contacts the die, and the target material is attached to the die under the action of negative pressure along with the gradual increase of the negative pressure in the sealed space IV; and the negative pressure assembly comprises: a negative pressure interface, an air pump (such as a peristaltic pump) connected with the negative pressure interface;

the power component is connected with the moving guide component so as to control the moving guide component to drive the lifting platform to move up and down.

In some embodiments, the cover 2 is rotatably coupled to the housing 1. Wherein a heating assembly for heating the target material is provided in the cover 2, the cover 2 is closed when the case is in a heating state, and the cover 2 is preferably rotated to be opened when the case is in a blowing or sucking state.

In some embodiments, at least one vent is provided on the mold (e.g., the concave portion of the mold) to avoid trapped air in the concave portion of the target material.

Different from the existing vacuum back suction molding scheme, in this embodiment, a technical route of blowing before suction is adopted, that is, a positive pressure component is firstly utilized to convert a target material from an initial state to a raised state which is adaptive to a mold structure (such as a mold height and the like), then a mold is made to be close to or attached to the raised target material, and then the raised target material is attached and molded on the mold by utilizing a negative pressure effect formed by a negative pressure component, so that molding preparation of the target material is completed. The scheme of blowing before sucking can effectively improve the product quality of the desktop-level plastic sucking machine or improve the preparation success rate.

Particularly, when the product (mold) to be prepared is a complex model, such as a building model, a building group model, a mountain model and the like, the height difference is large or the complex model has a plurality of protruding points, the suction-blowing integrated plastic suction machine in the embodiment can effectively avoid or relieve the damage condition of the target material.

The table top grade suction machine in this embodiment can expand the maximum molding height of the plastic sheet (i.e., the maximum height of the mold) to at least 200mm.

The suction and blowing integrated design in this embodiment can also alleviate the problem of trapped air to a certain extent, so that the setting amount or setting size of the exhaust hole on the mold can be reduced appropriately. Therefore, on one hand, the preparation difficulty of the die can be reduced, and meanwhile, the influence of the vent hole on the molding of the target material (such as avoiding hole printing on the target material) can be reduced.

In some embodiments, the target material is a plastic sheet, for example, the target material is one or more of the following: HIPS, ABS, PETG, PVC, PC.

In some embodiments, positive interface 131 and negative interface 141 may be the same interface.

Alternatively, in other embodiments, as shown in fig. 7, the positive pressure interface and the negative pressure interface may be two or more interfaces provided separately.

In some embodiments, a bonding region 103 is provided at the edge of the opening for bonding with the target material; and the mounting assembly 10 includes: the first pressing component 101 is used for pressing the target material in the lamination area, and when the first pressing component is installed at the opening of the box body, the lamination area formed below the first pressing component corresponds to the lamination area, so that the upper surface and the lower surface of the target material are respectively fixed. The mounting assembly in this embodiment can be used for fixedly mounting the plastic sheet on one hand, and can be used for forming a sealing space IV (avoiding or reducing the occurrence of air leakage) between the plastic sheet and the lifting platform in the air suction process on the other hand.

In some embodiments, the first press-fit 101 may be made of plastic.

In some embodiments, the first press-fit piece is a frame with an edge adapted to the shape of the opening of the box body,

and a pressing area corresponding to the attaching area is arranged below the frame.

In some embodiments, the bonding area 103 and/or the pressing area are made of rubber materials, so as to improve the tightness of the box space and more firmly mount the plastic sheet.

In some embodiments, the bonding area 103 and/or the bonding area is further provided with an anti-slip structure, such as an anti-slip texture on the surface of the bonding area or the bonding area.

In some embodiments, as shown in fig. 4, a third pressing member 104 is further disposed at the opening of the case.

Specifically, the third pressing member is a frame (or, a pressing plate) disposed along an edge of the opening of the box, and the frame is used for fixing and limiting the rubber material of the attaching region and the first pressing member 101 respectively.

In some embodiments, the upper and lower surfaces of the edges of the opening of the case are provided as an upper bonding region (e.g., bonding region 103) for contacting the target material, and a lower bonding region for mating with the lift platform, respectively. When the lifting platform ascends to the opening of the box body, the edge of the lifting platform is contacted with the lower attaching area, so that a negative pressure environment can be formed between the lifting platform and the target material rapidly.

In some embodiments, the mounting assembly as described in fig. 11-13 further comprises: the second press-fit piece 102 is provided with a second press-fit piece,

the second pressing member is used for controlling the pressing degree of the first pressing member 101; wherein the second press-fit piece 102 includes: the first rotating member 1021, the connecting member 1022, the fixing base 1023, and the second rotating member 1024 are sequentially connected; the first rotation member 1021 includes: a rotation connection part 1021a, and a rotation lever 1021b for controlling rotation of the rotation connection part, the second rotation member for pressing the first pressing member;

The first rotating member is rotatably connected with the first end of the connecting member and the first end of the second rotating member through a first rotating shaft 1025a and a second rotating shaft 1025b respectively; the second end of the connecting piece is rotationally connected with the fixed seat through a third rotating shaft 1025c, and the fixed seat is rotationally connected with the second end of the second rotating piece through a fourth rotating shaft 1025 d; when the rotating rod of the first rotating member rotates along the preset direction, the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft correspondingly rotate, so that the second rotating member correspondingly rotates under the action of the second rotating shaft and the fourth rotating shaft, and the pressure applied by the second rotating member to the first pressing member is gradually increased. The first pressing piece in the embodiment can conveniently realize the installation and fixation of the target material and the sealing of the inner space of the box body.

For example, in some embodiments, as shown in fig. 11-13, a second pressing member 102 is disposed on two sides of the opening of the case, where the second pressing member 102 includes: the first rotating member 1021, the connecting member 1022, the fixing base 1023, and the second rotating member 1024 are sequentially connected; wherein the first rotating member 1021 includes: a rotation connection portion 1021a, and a rotation lever 1021b for controlling rotation of the rotation connection portion, and an operator can operate the rotation lever 1021b to control rotation of the second rotation member, thereby directly or indirectly pressing the first pressing member through the second rotation member.

For example, in some embodiments, the first rotating member is rotatably connected to the first end of the connecting member and the first end of the second rotating member by a first shaft 1025a and a second shaft 1025b, respectively;

the second end of the connecting piece is rotatably connected with the fixing seat 1023 through a third rotating shaft 1025c, and the fixing seat is rotatably connected with the second end of the second rotating piece through a fourth rotating shaft 1025 d. That is, the first rotating member, the connecting member, the fixing seat and the second rotating member are connected with each other by the first rotating shaft, the third rotating shaft, the fourth rotating shaft and the second rotating shaft in sequence, so that the pressing distance of the second pressing member is controlled conveniently and stably in a limited adjustment interval (that is, the pressing distance of the second pressing member is relatively smaller).

For example, in some embodiments, the shaft includes, but is not limited to, the following types: intermittent stop shaft, flick shaft, damping shaft, gasket type shaft, rolling type shaft and sleeve shaft type shaft.

In some embodiments, for example, when the rotating lever of the first rotating member is rotated in a predetermined direction,

the first rotating member, the second rotating member, the third rotating member and the fourth rotating member rotate correspondingly, so that the second rotating member rotates correspondingly under the action of the second rotating member and the fourth rotating member, and the pressure applied by the second rotating member to the first pressing member is gradually increased. Conversely, when the first rotating member rotates in a direction opposite to the preset direction, the pressure applied by the second rotating member to the first pressing member gradually decreases, so that the operator can take out the molded target material.

For example, in some embodiments, as shown in fig. 11-13, the second rotating member 1024 includes: the rotating plate 10241, one side of the rotating plate 10241 is respectively provided with two openings, and the two openings of the rotating plate are respectively connected with the first rotating member 1021 and the fixed seat 1023 through the first rotating shaft and the second rotating shaft;

the other side of the rotation plate 10241 is provided with an opening 10241, and the rotation plate 10241 is sleeved on a fixing rod 10244 fixed to the opening of the case through the opening. Further, fixing bars 10244 are provided with fixing plates 10243, which can be used to limit the rotation angle of the rotation plate 10241, respectively, and nuts 10242 are provided on the fixing bars 10244 for fixing the fixing plates 10243. Wherein, the fixing rod is further provided with a pressing plate 10245 (specifically, the pressing plate may be disposed between one of the fixing plates and the nut), and the pressing plate 10245 may correspondingly reciprocate (or rotate) up and down in the process of reciprocating rotation of the rotating plate 10241, so as to adjust the pressing force of the pressing plate on the first pressing member 101.

For example, in some embodiments, the first pressing member is correspondingly provided with a protrusion corresponding to the pressing plate, and when the first pressing member is mounted at the opening of the case, the lower surface of the pressing plate contacts with the protrusion. Thus, when the pressing plate is gradually moved downward by the external force, the first pressing member presses the target material also by the pressing plate. Conversely, when the degree of compression of the compression plate is reduced, the operator may also manually lift the first compression member, thereby removing the target material.

In this embodiment, the operator can manually control the tightness degree of the lamination of the plastic sheets through the second lamination part, for example, for plastic sheets with different thicknesses and materials, or for production scenes with different deformation degrees (such as when the heights of the dies are different), and the operator can flexibly adjust the lamination degree of the plastic sheets by means of the second lamination part so as to meet the requirements of actual production scenes.

In this embodiment, the plastic sheet is directly mounted to the opening of the box, and is sealed and fixed by using the mounting component, so that the sealing performance of the box space below the plastic sheet is improved. Therefore, on one hand, the whole forming process can be directly finished at the opening, and a more visual observation space is improved for an operator (the operator can conveniently and manually regulate and control and intervene in the forming process); on the other hand, the mode of fixing the plastic sheet and moving the mold is adopted, so that the sealing performance of the inside of the box body can be ensured, and the blowing efficiency or the sucking efficiency (namely, the problem of air leakage is avoided or reduced) in the blowing and sucking processes is ensured.

In addition, the cover 2 of the vacuum molding machine may be in an open state (as shown in fig. 8) during the blow molding and vacuum molding processes.

In some embodiments, the case 1 is enclosed by four side walls, wherein a lifting guide assembly (e.g., a driving belt driven by a pulley) is disposed on at least one side wall along the height direction, and the lifting platform is connected with the lifting guide assembly, so as to implement up-and-down operation on the lifting mechanism.

In some embodiments, when at least two of the movement guide assemblies are provided, the movement guide assemblies are provided on both sides of the inside of the case, and a floor 16 is provided in the equipment space;

Accordingly, the power assembly 15 includes:

In some embodiments, as shown in fig. 1, a visible window 17 is provided on the case corresponding to the lifting space. Wherein the visual window may be used for observing the internal environment of the box, such as for observing the lifting state of the lifting platform.

In some embodiments, a control screen 18 is provided on the housing corresponding to the equipment space,

so that a user can control the operational state of at least one component in the device space through the control screen.

In some embodiments, the lifting platform is provided with a plurality of air holes for realizing up-down circulation of the air. Wherein, one side opening of the air hole is arranged on the upper surface of the lifting platform, and the other side opening of the air hole is connected with at least one air pump (such as a suction pump or an air blowing pump) through a pipeline.

Thereafter, as the target material is gradually attracted to the upper surface of the elevating platform by the negative pressure, the edge area of the target material can be rapidly fitted to each other with the elevating platform, thereby forming a sealed space IV between the lower surface of the target material and the upper surface of the elevating platform.

The air hole arrangement in the embodiment can further improve the forming efficiency on the basis of guaranteeing the forming quality.

s2, after the plastic sheet is heated and softened, blowing air by using a positive pressure assembly, and sealing the plastic sheet through a positive pressure interface 131

Positive pressure air is pumped into the closed box body 1 to positively blow and stretch the sheet;

s3, the lifting platform 12 for bearing the die moves upwards to the upper dead point, the negative pressure pump of the negative pressure assembly works, and air in the box body (such as a sealing space IV and the lifting platform) is discharged through the negative pressure interface 141 to form a negative pressure environment, so that the sheet is attached to the die, and the whole manufacturing process is completed.

In some embodiments, before the plastic sheet material secured at the opening of the case is softened by heating,

the plastic sheet can be sucked or blown by a blowing pump or a suction pump (or a negative pressure pump) to judge whether the plastic sheet is damaged or not.

The suction and blowing integrated process of the desktop-level plastic sucking machine is particularly suitable for preparing models with higher heights, such as building models and the like. Compared with the existing unidirectional negative pressure molding technology, the plastic sucking machine can prestretch the heated plastic sheet to a certain height, greatly improve the uniformity of the wall thickness of a model with higher height, and furthest reduce the manufacturing failure caused by the fact that the thin sheet with the wall thickness is broken.
