Description

[0001] Priority application

[0002] This application claims priority to the Chinese invention patent application numbered CN2023108977767, filed on July 20, 2023, entitled "A desktop blister machine based on reflective mirror heating", which is incorporated herein by reference in its entirety. Technical Field

[0003] The utility model relates to the technical field of desktop-level blistering, in particular to a cover body and a blistering machine based on reflective mirror heating. Background Art

[0004] The desktop vacuum forming machine is a small vacuum forming machine (Vacuum Former) suitable for manual operation.

[0005] It can be applied to the preparation of various plastic products, such as chocolate boxes, plastic packaging, prostheses, etc. Existing desktop blister machines usually heat the plastic sheet to a deformable state, then move the plastic sheet to the top of the mold, and then use a vacuum pump to suck air to make the plastic sheet fit the mold.

[0006] For example, see the patent application with application number CN202121464860.2, which discloses a desktop-level blister machine. The blister machine first heats the plastic sheet by a nano-infrared electric heating plate, and then manually rotates the mobile platform to lower the plastic sealing material to the mold after heating, and then blister molding. For another example, see the patent application with application number CN202121349674, which discloses a desktop-level vacuum reverse suction molding blister machine, which includes a frame, a blister mold placement table, a control module, and an electric heating device and a vacuum pumping device electrically connected to the control module. The blister machine also manually operates to move the heated plastic sheet downward to close to the mold, and then uses a vacuum pumping device to evacuate air so that the plastic sheet is attached to the outer surface of the mold under air pressure and cooled and molded.

[0007] The above-mentioned existing desktop blister machines have a relatively limited success rate or quality of sheet molding, especially when applied to molds with complex external structures, the success rate or quality of molding will be significantly reduced. For example, during the deformation of the plastic fitting mold, it is easy to break, resulting in processing failure. On the other hand, the working performance of this type of desktop blister machine is also relatively low (such as low heating efficiency and poor sealing). Utility Model Content

[0008] The purpose of the utility model is to provide a cover body and a blister machine based on reflective mirror heating, which can partially solve or alleviate the above-mentioned shortcomings in the prior art and improve the quality of plastic products to a certain extent.

[0009] In order to solve the above-mentioned technical problems, this application specifically adopts the following technical solutions:

[0010] In a first aspect of the present application, a cover body is provided, wherein a heating component is disposed inside the cover body, and the heating component comprises:

[0011] a first specular reflector disposed on the top plate inside the cover; a second specular reflector disposed on at least one side wall inside the cover; the first specular reflector and the second specular reflector on at least one side wall enclose a heat collecting space;

[0012] at least one heating element, the heating element being arranged in the heat collecting space and configured to emit at least one radiation line;

[0013] Among them, when the cover is closed and the heating element is in a heating state, at least one of the radiation lines will be reflected at least once on the first mirror reflection plate and the second mirror reflection plate, and then move to the lower bottom surface of the heat collection space; among them, after multiple radiation lines are reflected at least twice, they are evenly dispersed and reflected in the lower bottom surface of the heat collection space.

[0014] In some embodiments, the first mirror reflection plate and four second mirror reflection plates adjacently arranged along the side edges of the first mirror reflection plate together enclose the heat collecting space in a rectangular table structure.

[0015] In some embodiments, the heating element is an infrared heating tube, and the corresponding radiation is infrared radiation.

[0016] In some embodiments, the lower bottom surface of the heat collecting space is open to reserve installation space for the target material to be formed.

[0017] The present application also provides a blister machine, comprising:

[0018] A box body, wherein the opening of the box body is used to place the target material to be formed;

[0019] and a cover body matched with the box body, wherein a heating component is arranged inside the cover body, and the heating component comprises:

[0020] a first specular reflector disposed on the top plate inside the cover; a second specular reflector disposed on at least one side wall inside the cover; the first specular reflector and the second specular reflector on at least one side wall enclose a heat collecting space;

[0021] at least one heating element, the heating element being arranged in the heat collecting space and configured to emit at least one radiation line;

[0022] Among them, when the cover is closed and the heating element is in a heating state, at least one of the radiation lines will be reflected at least once on the first mirror reflection plate and the second mirror reflection plate, and then contact the target material; wherein multiple radiation lines are evenly dispersed and reflected on the target material after at least two reflections.

[0023] In some embodiments, the heat collecting space is in the form of a rectangular table structure; and / or the radiation is infrared.

[0024] In some embodiments, the target material is a plastic sheet.

[0025] In some embodiments, a fitting area for fitting with the target material is provided at the edge of the opening, and the blister machine further includes: a first pressing member for pressing the target material to the fitting area, and when the first pressing member is installed at the opening, the pressing area formed under the first pressing member corresponds to the fitting area, thereby fixing the upper and lower surfaces of the target material respectively.

[0026] In some embodiments, the contact area and / or the pressing area is also provided with an anti-slip structure.

[0027] In some embodiments, the heating element is an infrared heating tube, and both ends of the infrared heating tube are respectively fixed to the second mirror reflection plate.

[0028] Beneficial technical effects:

[0029] The utility model provides a desktop-level technical solution that uses a suction-blowing integrated design and a new lifting mode (i.e., fixing the target material at the opening of the box body and moving the mold to fit the material) to cooperate with each other. On the one hand, the uniformity of the film thickness of the plastic sheet during the entire molding process is improved to improve the success rate and quality of product preparation. At the same time, the cooperation between the new lifting mode and the sealing installation component effectively improves the suction-blowing efficiency of the positive pressure component or the negative pressure component (such as improving the formation efficiency of the sealed space III).

[0030] The utility model also provides a low-power uniform heating solution, in which a first mirror reflector, a second mirror reflector and a plurality of arranged heating tubes are used to cooperate with each other. On the one hand, the reflector is used to collect heat to improve the heating efficiency, and on the other hand, the reflector is used to cooperate with the regularly arranged heating tubes to improve the uniformity of the material being heated. The uniform heating of the target material can further improve the quality of the formed product.

[0031] Moreover, in the plastic forming process (such as plastic forming and blow molding) of the blister machine in this embodiment, the cover can be opened directly without causing too much influence on the suction and blowing process of the forming process, and the plastic sheet can be arranged at the opening of the box body during the whole process. Therefore, when the operator uses the blister machine for forming, he can visually observe the deformation degree of the plastic sheet (such as the degree of bulge, the degree of fit with the mold, etc.), which is conducive to the operator to automatically adjust the suction force or blowing force according to actual needs (such as plastic deformation ability, mold height, etc.). And this open forming environment is also conducive to improving the demoulding success rate of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0058] Herein, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings by themselves. Therefore, "module", "component" or "unit" can be used mixedly.

[0059] In this document, the terms "upper", "lower", "inner", "outer", "front", "back", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0060] In this document, unless otherwise expressly specified or limited, the terms "installed", "provided with", "connected" and "connected" shall mean

[0061] The term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field,

[0062] The specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] Herein "and / or" includes any and all combinations of one or more of the associated listed items.

[0064] Herein, "plurality" means two or more than two, ie, it includes two, three, four, five, etc.

[0065] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0066] As used in this specification, the term "about" typically means + / - 5% of the stated value.

[0067] More typically, + / - 4% of the stated values, more typically, + / - 3% of the stated values, more typically, + / - 2% of the stated values, even more typically, + / - 1% of the stated values, even more typically,

[0068] + / - 0.5%.

[0069] In this specification, certain embodiments may be disclosed in a format of being in a certain range. It should be understood that such description of "being in a certain range" is merely for convenience and brevity, and should not be interpreted as a rigid limitation on the disclosed range. Therefore, the description of the range should be considered to have specifically disclosed all possible sub-ranges and independent numerical values ​​within this range. For example, the description of the range 1 to 6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as individual numbers within this range, such as 1, 2, 3, 4, 5 and 6. Regardless of the breadth of the range, the above rules apply.

[0070] While an object emits radiation energy outward, it also continuously absorbs radiation energy emitted by other objects around it and converts it back into heat energy. This heat transfer process of mutual emission and absorption of radiation energy between objects is called radiation heat transfer.

[0071] Among them, radiation energy is transmitted through radiation lines, which are also called electromagnetic waves.

[0072] For example, an infrared heating tube is a device that uses the principle of infrared radiation to achieve heating. Its working principle is to generate heat in the heating tube through electric current, and then convert the heat into infrared radiation, and then transfer the heat energy to the heated object. Correspondingly, when the heating element is an infrared heating tube, the radiation refers to infrared rays.

[0073] Desktop blister machines can be widely used in industrial or non-industrial preparation and utilization. For example, for 3D printing or DIY enthusiasts, desktop blister machines are usually selected to prepare various small products or product accessories in a home environment, such as masks, toy cars, architectural models, mountain models, auto parts, etc. However, the current desktop blister machines have a low success rate in preparing products or product quality deviations on the one hand, and a relatively high application cost for home scenes on the other hand (such as relatively high power consumption). In order to better meet the application needs in the field of desktop blister technology, the utility model provides a desktop blister machine with better molding efficiency and better molding quality.

[0074] Embodiment 1

[0075] like Figure 1-Figure 16 As shown, the utility model provides a desktop blister machine with blowing and suction integration.

[0076] include:

[0077] A box body 1, and a cover body 2 matched with the box body; wherein,

[0078] An installation component 10 is provided at the opening of the box body, and the installation component is used to install the target material 3;

[0079] The box 1 is provided with a lifting space I and an equipment space II in sequence; wherein the lifting space I is provided with a lifting platform 12 for carrying a mold (such as a plastic mold such as a building model or a car model), and at least one moving guide assembly 11 for allowing the lifting platform to move up and down in the lifting space;

[0080] The equipment space is provided with an air bleed assembly and a power assembly 15;

[0081] The air bleed assembly is used to pump positive pressure gas into the box after the target material is heated to a corresponding state, so that the target material is deformed under the corresponding positive pressure and transformed into a bulging state; and the air bleed assembly includes: a first air bleed interface, an air pump connected to the first air bleed interface;

[0082] The air induced component is also used to, when the target material is close to or in contact with the mold, suction air so that the upper surface of the lifting platform 12 and the target material 3 are in contact with each other and enclose a sealed space; wherein, as the negative pressure in the sealed space gradually increases, the gas between the target material and the mold will be discharged through at least one exhaust hole on the mold, and the target material will also be bonded to the mold under the action of the negative pressure.

[0083] In some embodiments, blowing and suction can share the same air inlet interface and air pump.

[0084] Alternatively, in other embodiments, blowing and suction may also be performed using independent air inlet interfaces or air pumps.

[0085] For example, in some embodiments, the bleed air component includes: a positive pressure component 13 and a negative pressure component 14 .

[0086] The equipment space is provided with a positive pressure component 13, a negative pressure component 14, and a power component 15;

[0087] The positive pressure component is used to pump positive pressure air (i.e., blow air) into the box after the target material is heated to a corresponding state, so that the target material is uniformly deformed under the corresponding positive pressure (wherein, uniform deformation may refer to a state in which the deformation degree or stress magnitude at each site of the target material is equal or approximately equal), and is transformed into a bulging state; and the positive pressure component includes: a positive pressure interface 131 (equivalent to a first air inlet interface), and an air pump (such as an air pump) connected to the positive pressure interface 131;

[0088] The negative pressure component is used to make the upper surface of the lifting platform 12 and the lower surface of the target material 3 contact each other and enclose a sealed space IV by suction when the target material approaches or contacts the mold. As the negative pressure in the sealed space IV gradually increases, the target material will also be bonded to the mold under the action of the negative pressure. The negative pressure component includes: a negative pressure interface (equivalent to a second air inlet interface), and an air pump (such as a peristaltic pump) connected to the negative pressure interface;

[0089] The power assembly is connected to the moving guide assembly to control the moving guide assembly to drive the lifting platform to move up and down.

[0090] In some embodiments, the cover 2 is rotatably connected to the box 1. A heating component for heating the target material is disposed in the cover 2. When the box is in a heating state, the cover 2 is closed, and when the box is in a blowing or suction state, the cover 2 is preferably rotated to open.

[0091] In some embodiments, at least one vent hole is provided on the mold (such as the concave portion of the mold).

[0092] This is to avoid the target material from forming trapped air in the concave area.

[0093] Different from the existing vacuum reverse suction molding scheme, this embodiment adopts the technical route of blowing first and then sucking, that is, first using the positive pressure component to convert the target material from the initial state to a raised state that is compatible with the mold structure (such as mold height, etc.), then making the mold close to or fit to the raised target material, and then using the negative pressure formed by the negative pressure component to fit the raised target material on the mold to form, thereby completing the molding preparation of the target material. This scheme of blowing first and then sucking can effectively improve the product quality of desktop-level blister machines or improve the preparation success rate.

[0094] Especially when the product (mold) to be prepared is a complex model, such as a building model, a building complex model, a mountain model, or other complex models with large height differences or multiple protrusions, the integrated suction and blowing blister machine in this embodiment can effectively avoid or alleviate the damage of the target material.

[0095] The desktop blister machine in this embodiment can expand the maximum molding height of the plastic sheet (ie the maximum height of the mold) to at least 200 mm.

[0096] The integrated suction and blowing design in this embodiment can also alleviate the problem of trapped air to a certain extent, so that the number or size of the exhaust holes on the mold can be appropriately reduced. Thus, on the one hand, the difficulty of preparing the mold can be reduced, and on the other hand, the influence of the exhaust holes on the molding of the target material can be reduced (such as avoiding hole marks on the target material).

[0097] 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.

[0098] In some embodiments, the positive pressure interface 131 and the negative pressure interface 141 may be the same interface.

[0099] Or, in other embodiments, Figure 7 As shown, the positive pressure interface and the negative pressure interface can be two or more interfaces that are respectively set.

[0100] In some embodiments, a fitting area 103 for fitting with the target material is provided at the edge of the opening; and the installation assembly 10 includes: a first pressing member 101 for pressing the target material to the fitting area, and when the first pressing member is installed at the opening of the box, the pressing area formed below the first pressing member corresponds to the fitting area, thereby fixing the upper and lower surfaces of the target material respectively. The installation assembly in this embodiment can fix the plastic sheet on the one hand, and on the other hand, can quickly form a sealed space IV between the plastic sheet and the lifting platform during the suction process (avoiding or reducing the occurrence of air leakage).

[0101] In some embodiments, the first pressing piece 101 may be made of plastic.

[0102] In some embodiments, the first pressing piece is a frame whose edge is adapted to the shape of the box opening.

[0103] A pressing area corresponding to the laminating area is arranged below the frame.

[0104] In some embodiments, the fitting area 103 and / or the pressing area is made of rubber material to improve the sealing of the box space and to more firmly install the plastic sheet.

[0105] In some embodiments, the bonding area 103 and / or the pressing area is further provided with an anti-slip structure, such as anti-slip lines are provided on the surface of the bonding area or the pressing area.

[0106] In some embodiments, Figure 4 As shown, a third pressing piece 104 is also provided at the opening of the box body.

[0107] Specifically, the third pressing piece is a frame (or a pressing plate) arranged along the edge of the box opening, and the frame is used to fix and limit the rubber material in the fitting area and the first pressing piece 101 respectively.

[0108] In some embodiments, the upper and lower surfaces of the edge of the opening of the box are respectively configured as an upper bonding area (such as bonding area 103) for contacting the target material and a lower bonding area for cooperating with the lifting platform. When the lifting platform rises to the opening of the box, the edge of the lifting platform contacts the lower bonding area, so that a negative pressure environment can be quickly formed between the lifting platform and the target material.

[0109] In some embodiments, Figure 11-13 The installation assembly further includes: a second pressing member 102,

[0110] The second pressing member is used to control the pressing degree of the first pressing member 101; wherein the second pressing member 102 comprises: a first rotating member 1021, a connecting member 1022, a fixing seat 1023 and a second rotating member 1024 connected in sequence; the first rotating member 1021 comprises: a rotating connecting portion 1021a and a rotating rod 1021b for controlling the rotation of the rotating connecting portion, and the second rotating member is used to press the first pressing member;

[0111] The first rotating member is rotatably connected to the first end of the connecting member and the first end of the second rotating member through the first rotating shaft 1025a and the second rotating shaft 1025b respectively; the second end of the connecting member is rotatably connected to the fixing seat through the third rotating shaft 1025c, and the fixing seat is rotatably connected to the second end of the second rotating member through the fourth rotating shaft 1025d; when the rotating rod of the first rotating member rotates along the preset direction, the first, second, third and fourth rotating shafts will rotate correspondingly, so that the second rotating member rotates correspondingly under the action of the second rotating shaft and the fourth rotating shaft, thereby gradually increasing the pressure applied by the second rotating member to the first pressing member. The first pressing member in this embodiment can conveniently realize the installation and fixation of the target material and the sealing of the internal space of the box.

[0112] For example, in some embodiments, Figure 11-13 As shown, a second pressing piece 102 is respectively arranged on both sides of the box opening, and the second pressing piece 102 includes: a first rotating piece 1021, a connecting piece 1022, a fixing seat 1023 and a second rotating piece 1024 connected in sequence; wherein, the first rotating piece 1021 includes: a rotating connecting part 1021a, and a rotating rod 1021b for controlling the rotation of the rotating connecting part, and the operator can operate the rotating rotating rod 1021b to control the rotation of the second rotating piece, and then directly or indirectly press the first pressing piece through the second rotating piece.

[0113] 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 through the first rotating shaft 1025a and the second rotating shaft 1025b respectively;

[0114] The second end of the connecting member is rotatably connected to the fixing seat 1023 via the third rotating shaft 1025c, and the fixing seat is rotatably connected to the second end of the second rotating member via the fourth rotating shaft 1025d. That is, the first rotating member, the connecting member, the fixing seat, and the second rotating member are connected to each other in pairs via 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 can be conveniently and stably controlled within a limited adjustment range (i.e., the pressing distance of the second pressing member is relatively small).

[0115] For example, in some embodiments, the rotating shaft includes but is not limited to the following types: an intermittent stop rotating shaft, a spring-open rotating shaft, a damping rotating shaft, a gasket rotating shaft, a rolled rotating shaft, and a sleeve rotating shaft.

[0116] For example, in some embodiments, when the rotating rod of the first rotating member rotates along a preset direction,

[0117] The first, second, third, and fourth rotating shafts will rotate correspondingly, so that the second rotating member rotates correspondingly under the action of the second rotating shaft and the fourth rotating shaft, thereby gradually increasing the pressure applied by the second rotating member to the first pressing member. On the contrary, 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 formed target material.

[0118] For example, in some embodiments, Figure 11-13 As shown, the second rotating member 1024 includes: a rotating plate 10241, and two openings are respectively provided on one side of the rotating plate 10241, and the two openings of the rotating plate are respectively connected to the first rotating member 1021 and the fixing seat 1023 through the first rotating shaft and the second rotating shaft;

[0119] An opening 10241 is provided on the other side of the rotating plate 10241, and the rotating plate 10241 is sleeved on a fixing rod 10244 fixed to the opening of the box body through the opening. Further, the fixing rod 10244 is respectively provided with fixing plates 10243 above and below, which can be used to limit the rotation angle of the rotating plate 10241, and the fixing rod 10244 is also provided with nuts 10242 above and below for fixing the fixing plate 10243. Among them, a pressing plate 10245 is also provided on the fixing rod (specifically, the pressing plate can be provided between one of the fixing plates and the nut), and the pressing plate 10245 can be correspondingly reciprocated up and down (or rotated) during the reciprocating rotation of the rotating plate 10241, so as to adjust the pressing force of the second pressing member on the first pressing member 101.

[0120] For example, in some embodiments, the first pressing member is provided with a protrusion corresponding to the pressing plate, and when the first pressing member is installed at the opening of the box body, the lower surface of the pressing plate contacts the protrusion. Thus, when the pressing plate gradually moves downward under the action of an external force, the first pressing member also presses the target material under the action of the pressing plate. Conversely, when the degree of compression of the pressing plate decreases, the operator can also manually lift the first pressing member to remove the target material.

[0121] In this embodiment, the operator can manually control the tightness of the pressing of the plastic sheet through the second pressing piece. For example, for plastic sheets of different thicknesses and materials, or for production scenarios with different degrees of deformation (such as different mold heights), the operator can use the second pressing piece to flexibly adjust the pressing degree of the plastic sheet to meet the needs of the actual production scenario.

[0122] In this embodiment, the plastic sheet is directly installed at the opening of the box body, and the installation assembly is used to seal and fix it, so that the sealing performance of the box body space below the plastic sheet is improved. Therefore, on the one hand, the entire molding process can be completed directly at the opening, providing the operator with a more intuitive observation space (facilitating the operator's manual adjustment and intervention during the molding process); on the other hand, the method of fixing the plastic sheet and moving the mold can ensure the sealing performance inside the box body, thereby ensuring the blowing efficiency or the suction molding efficiency of the blow molding and suction molding process (that is, avoiding or reducing the problem of air leakage).

[0123] In addition, during the blow molding and blister molding process, the cover 2 of the blister molding machine can be in an open state (such as Figure 8 As shown). This can also increase the demoulding efficiency or demoulding success rate of the plastic sheet to a certain extent, such as avoiding demoulding failure due to overheating of the material.

[0124] In some embodiments, Figure 14-17 As shown, the movable guide assembly 11 includes: a guide rod 111; a transmission component 112, the transmission component includes: a first driving wheel 112-1, a first driven wheel 112-2, and a first transmission belt 112-3 arranged on the first driving wheel and the first driven wheel, the first driving wheel is connected to the output end of the power assembly; a support member 113, the support member is used to support and fix the lifting platform, and the support member 113 is respectively connected to the guide rod 111 and the first transmission belt 112-3 through a sliding member 114, so that the lifting platform can be driven to move up and down under the guidance of the guide rod and the first transmission belt.

[0125] In some embodiments, the box body 1 is surrounded by four side walls, wherein a lifting guide assembly (for example, a transmission belt driven by a pulley) is arranged along the height direction on at least one side wall, and the lifting platform is connected to the lifting guide assembly, thereby realizing up and down movement in the lifting mechanism.

[0126] In some embodiments, when at least two said movement guide assemblies are provided, said movement guide assemblies are provided on both sides of the interior of said box body, and a bottom plate 16 is provided in said equipment space;

[0127] Accordingly, the power assembly 15 comprises:

[0128] A motor 151, a transmission rod 152, wherein the transmission rod is connected to the first output end of the motor through a second transmission belt, and the two output ends of the transmission rod are respectively connected to the first driving wheels on both sides; a fixed plate 153, wherein the fixed plate 153 is respectively provided with a first hole and a second hole, and the first output end 151a of the motor and the transmission rod 152 respectively pass through the first hole and the second hole, and the fixed plate 153 is fixed to the base plate.

[0129] Preferably, in this embodiment, by correspondingly setting two groups of movable guide components and synchronously controlling the two groups of guide components by the power component, the lifting platform can drive the mold to maintain good stability during the rapid lifting process of electric control.

[0130] In some embodiments, the positive pressure component and the negative pressure component are respectively arranged on both sides of the power component in the equipment space.

[0131] For example, in some embodiments, the vacuum pump and the peristaltic pump are respectively arranged on both sides of the motor, so that the center of gravity of the blister machine is located in the bottom middle area of ​​the box body, thereby ensuring the stability of the blister machine.

[0132] Alternatively, in other embodiments, the positive pressure component and the negative pressure component may share an interface and an air pump, that is, the positive pressure interface and the negative pressure interface are one interface, and the positive pressure component and the negative pressure component may also share an air pump with suction and blowing functions.

[0133] In some embodiments, Figure 1 As shown, a visual window 17 is provided on the box body corresponding to the lifting space. The visual window can be used to observe the internal environment of the box body, such as to observe the lifting state of the lifting platform.

[0134] In some embodiments, a control panel 18 is provided on the box body corresponding to the equipment space.

[0135] So that the user can control the operating status of at least one component in the device space through the control screen.

[0136] For example, in some embodiments, the user can control the heating temperature of the heating component, the blowing data of the positive pressure component (such as controlling the bulge height H of the target material), etc. through the control screen.

[0137] In some embodiments, the lifting platform is provided with a plurality of air holes for realizing the upward and downward circulation of gas, wherein one opening of the air hole is provided on the upper surface of the lifting platform, and the other opening of the air hole is connected to at least one air pump (such as a suction pump or a blowing pump) through a pipeline.

[0138] In some embodiments, in order to improve the stability and uniformity of the deformation of the plastic material during the blow molding process (i.e., the blowing process), the multiple air holes of the lifting platform are evenly arranged, and the aperture r of the openings of the air holes on the upper surface of the lifting platform is approximately 0.3mm-0.8mm, and the spacing between adjacent air holes is less than or equal to 10r.

[0139] In some embodiments, before the lifting platform contacts the target material, the negative pressure assembly can be used to pre-evacuate (or pre-inhale) each air hole in the lifting platform to form a preliminary negative pressure environment inside the lifting platform (such as inside the air hole). Thereafter, when the target material is gradually attracted to the upper surface of the lifting platform by the negative pressure, the edge area of ​​the target material can quickly fit with the lifting platform, thereby forming a sealed space IV between the lower surface of the target material and the upper surface of the lifting platform.

[0140] The pore arrangement in this embodiment can further improve the molding efficiency while ensuring the molding quality.

[0141] In some embodiments, at least one pipe interface is connected to the lifting platform, and at least one of the pipe interfaces can be connected to a negative pressure interface and a positive pressure interface through a pipe.

[0142] For example, in some embodiments, two pipeline interfaces may be provided to be connected to the negative pressure interface and the positive pressure interface one by one.

[0143] In some embodiments, the target material has a thickness of approximately 0.5-4 mm.

[0144] In some embodiments, the bulge height H of the target material is greater than or equal to one third of the height of the mold, so that the target material is effectively pre-stretched.

[0145] In some embodiments, the negative pressure air provided by the suction pump is generally at a pressure of tens of KPa.

[0146] Specifically, in some embodiments, the working process of the blow molding machine in the present application is as follows:

[0147] S1, firstly, the plastic sheet is heated and softened by using the heating component of the cover body 2;

[0148] S2, the plastic sheet is heated and softened, and then air is blown into the sealant through the positive pressure interface 131.

[0149] Positive pressure air is pumped into the closed box 1 to positively blow and stretch the sheet;

[0150] S3, the lifting platform 12 used to support the mold then moves upward to the upper dead point, the negative pressure pump of the negative pressure component starts to work, and the air inside the box (such as the sealed space IV, the lifting platform) is discharged through the negative pressure interface 141 to form a negative pressure environment, so that the sheet fits the mold, thereby completing the entire manufacturing process.

[0151] In some embodiments, before the plastic sheet fixed to the opening of the box is heated and softened,

[0152] Alternatively, an air pump or a suction pump (or a negative pressure pump) may be used to suck or blow air into the sheet to determine whether the plastic sheet is damaged.

[0153] The suction-blowing integrated process of the desktop blister machine in the utility model is particularly suitable for preparing models with higher heights, such as building models, etc. Compared with the existing one-way negative pressure molding technology, the blister machine in the utility model can pre-stretch the heated plastic sheet to a certain height, greatly improving the uniformity of the wall thickness of the model with higher heights, and minimizing the manufacturing failure caused by the sheet being torn due to the wall thickness being too thin.

[0154] Correspondingly, the present application can also provide an installation assembly for a blister machine, the blister machine comprising: a box body 1, a lifting platform 12 for carrying the mold is arranged in the box body 1, the lifting platform reciprocates up and down in the box body under the action of the moving guide assembly 11; an air bleed assembly is also arranged in the box body, the air bleed assembly blows in or sucks out the air in the box body 1

[0155] air, so as to form a corresponding positive pressure space or negative pressure space in the box;

[0156] Wherein, the edge of the opening of the box is provided with a contact for fitting with the target material.

[0157] Correspondingly, the installation assembly 10 includes:

[0158] The first pressing member 101 is used to press the target material to the bonding area, and when the first pressing member is installed at the opening of the box, the pressing area formed below the first pressing member corresponds to the bonding area, thereby fixing the upper and lower surfaces of the target material respectively.

[0159] It can be understood that the mounting assembly in this embodiment may include the same or similar structure as any embodiment in this document.
