Description

Technical Field

[0001] The present application relates to the technical field of blister machines, and in particular to an adjustable blister packaging machine. Background Art

[0002] Blister packaging is a commonly used method in the packaging industry. Blister packaging machines are machines that absorb heated and plasticized thermoplastic plastic coils such as PVC and PE into high-end packaging decoration boxes, frames and other products in various shapes. They are widely used in the machinery industry, electronics, food, medical and other fields.

[0003] The authorization publication number CN116214897B discloses a blister forming device for pallet production. By extracting the air in the molding cavity through a negative pressure pump, a downward suction force is first generated at the circular hole to pull the material downward and deform it. When the material blocks the circular hole, a suction force that expands outward is generated at the side hole, causing the heated material to expand outward and deform, completing the blister forming work, thereby ensuring that the thickness of the blister tray after molding is uniform.

[0004] It can be seen that during the use of the existing blister forming machine, the outer wall of the molded model will fit closely to the inner wall of the mold after deformation, and the mold has residual temperature after molding, which makes it difficult to demold the molded model from the mold.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions 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.

[0035] like Figure 1-Figure 9 As shown, an adjustable blister packaging machine proposed in an embodiment of the present application includes a bearing seat 1, a frame 2 is installed on the bearing seat 1, a hydraulic cylinder 3 is installed on the frame 2, the telescopic end of the hydraulic cylinder 3 faces downward and is installed with a connecting rod 4, and an upper pressing plate 5 is sleeved on the bottom end of the connecting rod 4. The blister packaging machine also has a heating component for heating the thermoplastic material, and a conveying component for conveying the heated thermoplastic material is also installed on the bearing seat 1. All of them are structures on the existing blister packaging machine, and also include:

[0036] The molding mechanism 6 includes a mold box 601 installed on the bearing seat 1. The mold box 601 is located below the upper pressing plate 5 and has an opening at the top. The open end of the mold box 601 is used to place a concave mold 603. The concave mold 603 can be fixed to the mold box 601 by bolts. The top of the concave mold 603 is used to place the heated thermoplastic material. The concave mold 603 is an existing mold for placing in the mold box 601. The bottom of the concave mold 603 is provided with an air suction hole 602 for sucking out the air between the concave mold 603 and the thermoplastic material.

[0037] The cooling mechanism 7 is mounted on the bearing seat 1 and is used to transport a flowing cooling medium into the mold box 601. In this embodiment, the cooling medium may be water or cooling oil.

[0038] The suction mechanism 8 is mounted on the cooling mechanism 7 and communicated with the suction hole 602, and is used to provide suction force in the suction hole 602 in a direction away from the mold box 601. In this embodiment, the suction mechanism 8 can be a device for vacuuming in an existing blister packaging machine;

[0039] The ejection mechanism 9 includes an ejection member 901 and a blocking member 902 installed on the cooling mechanism 7. The blocking member 902 is used to block the air suction hole 602. The ejection member 901 can pass through the air suction hole 602 to eject the model after the vacuum forming. That is to say, when in use, the thermoplastic material is first heated by the heating component, and the heated thermoplastic material is placed on the open end of the die 603 by the conveying component. Then, the upper pressing plate 5 is moved downward by the hydraulic cylinder 3 to press the open end of the die 603. At this time, the upper pressing plate 5 and the die 603 press the thermoplastic material, and then the suction hole 602 is sucked by the suction mechanism 8 to make the thermoplastic material fit the mold, and then the suction hole 602 is blocked by the blocking member 902 to prevent the subsequent cooling medium from entering the die 603, and then the cooling mechanism 7 is used to The cooling medium is transported to the mold box 601, and the cavity 603 is cooled by heat transfer, so that the molded model can be quickly cooled. Due to the principle of thermal expansion and contraction, the mold will shrink to a certain extent after molding, which is convenient for subsequent lifting. Finally, the lifting member 901 passes through the air intake hole 602 of the cavity 603 to lift the molded material to achieve rapid demolding. The cavity 603 can be of different shapes, but the position of the air intake hole 602 needs to ensure that the lifting member 901 can pass through the air intake hole 602, and the blocking member 902 can block the air intake hole 602. Compared with the prior art, the present application can quickly cool the mold through the cooling mechanism 7, and then cooperate with the lifting member 901 to eject the model formed in the cavity 603, so that the molded model can be quickly taken out after the thermoplastic material is molded, thereby improving efficiency.

[0040] like Figure 5 and Figure 8As shown, in some embodiments, the cooling mechanism 7 includes a water tank 701 installed on the supporting seat 1, and the top of the water tank 701 is vertically connected to a water inlet pipe 702, and one side of the water inlet pipe 702 is connected to a water supply pipe 703, and a connecting hole 704 is opened at the bottom of the mold box 601, and the free end of the water supply pipe 703 is connected to the edge of the connecting hole 704. When the suction mechanism 8 vacuum-forms the thermoplastic material in the concave mold 603, the water in the water tank 701 enters the mold box 601 from the water supply pipe 703. That is to say, after the vacuum forming is completed, the water in the water tank 701 will directly enter the mold box 601, and no additional driving force is required, such as using a water pump to pump water into the mold box 601.

[0041] like Figure 1-Figure 3 As shown, in some embodiments, the suction mechanism 8 includes a suction pump 801 installed on one side of the water tank 701, and a first connecting pipe 802 is connected between one end of the suction pump 801 and a position near the top surface of one side of the mold box 601, the interior of the connecting rod 4 is hollow and the bottom is open, and a second connecting pipe 803 is connected between one side of the connecting rod 4 and the other end of the suction pump 801, and a vent hole 804 is opened through the top of the upper pressing plate 5, that is, when the suction pump 801 is started, air will be sucked into the first connecting pipe 802 and air will be discharged from the second connecting pipe 803, so the suction force generated by the first connecting pipe 802 will suck the thermoplastic material located on the end face of the die 603 into the die 603, and the second connecting pipe 803 will push the thermoplastic material in the die 603 into the die 603, which not only ensures that the thermoplastic material can fit well on the inner wall of the die 603, but also can To prevent the thermoplastic material from sticking to the upper pressing plate 5, when the thermoplastic material is attached to the concave mold 603, the air suction hole 602 will be blocked. At this time, negative pressure will be generated in the water inlet pipe 702, so that the water in the water storage tank 701 is pumped into the water inlet pipe 702. Because the water inlet pipe 702 is connected with the water delivery pipe 703, the water will enter the water delivery pipe 703 and then enter the mold box 601, so that the water in the mold box 601 and the concave mold 603 are connected. 03 contact to cool the die 603, and because a vent hole 804 is provided on the upper pressing plate 5, the air between the upper pressing plate 5 and the thermoplastic material will flow out from the vent hole 804, and the vent hole 804 has a small aperture. The air will flow out from the vent hole 804 when there is a certain pressure between the upper pressing plate 5 and the thermoplastic material, thereby the water in the water tank 701 is drawn into the mold box 601 through negative pressure to achieve cooling of the die 603.

[0042] like Figure 3 , Figure 5 and Figure 8As shown, in some embodiments, a connecting sleeve rod 9021 is vertically connected between the top end of the water inlet pipe 702 and the water delivery pipe 703, and the blocking member 902 includes a long rod 9022 that is vertically slidably inserted in the connecting sleeve rod 9021. The bottom end of the long rod 9022 is located in the water inlet pipe 702 and is installed with a buoyancy member 9023. The buoyancy member 9023 is located below the connection between the water inlet pipe 702 and the water delivery pipe 703. The top end of the long rod 9022 passes through the connecting sleeve rod 9021 and is located in the mold box 601 and is constructed with a blocking block 9024, which is used to block the air intake hole 602. The water level of the water tank 701 is located in the water inlet pipe 702 and the buoyancy member 9023 floats on the water surface. That is to say, under normal circumstances, the horizontal plane in the water tank 701 is located in the water inlet pipe 702 and The buoyancy member 9023 floats on the water surface. At this time, the blocking block 9024 does not block the air intake hole 602. When negative pressure is generated, the water level in the water inlet pipe 702 rises, so that the buoyancy member 9023 floats upward until the blocking block 9024 blocks the air intake hole 602. At this time, the water level continues to rise and submerges the buoyancy member 9023. At this time, the density of the buoyancy member 9023 is less than that of water, so the blocking block 9024 will always block the air intake hole 602. In the process of water entering the water supply pipe 703 from the water inlet pipe 702, the water inlet pipe 702 always remains in water. Therefore, when the water in the mold box 601 rises, the water will not enter the concave mold 603 from the air intake hole 602, and no additional driving force is required to drive the blocking block 9024 to move.

[0043] like Figure 3 , Figure 5 and Figure 8As shown, in some embodiments, a through hole 9011 is formed through the top of the blocking block 9024, a sliding cavity 9012 connected to the through hole 9011 is configured in the long rod 9022, and the lifting member 901 includes a sliding block 9013 vertically slidably arranged in the sliding cavity 9012, and a top rod 9014 located in the through hole 9011 is vertically configured on the top of the sliding block 9013, and the top rod 9014 is clearance-matched with the through hole 9011, and a return spring 9015 is installed between the sliding block 9013 and the sliding cavity 9012, and a drainage hole 9016 is formed on one side of the sliding block 9013, and one end of the drainage hole 9016 extends into the long rod 9022 and The drainage hole 9016 is connected to the slide cavity 9012, and one end of the slide cavity 9012 is located below the sliding block 9013. In this embodiment, when the water level inside the mold box 601 is higher than the blocking block 9024, the water level continues to rise, thereby submerging the blocking block 9024. At this time, part of the water will enter the drainage hole 9016, and the water will enter the slide cavity 9012. As the water level in the slide cavity 9012 rises, the sliding block 9013 is pushed up, and then the push rod 9014 passes through the suction hole 602 to push up the cooled molded model. It should be noted that the first connecting pipe 802 is located at the blocking block 902. 4, and the farther the distance between the first connecting pipe 802 and the blocking block 9024 is, the greater the water pressure in the sliding cavity 9012 will be when the water level rises, and because the thermoplastic material is light in weight, the ejector 9014 has enough power to lift up the molded model, so when the mold box 601 is designed, the height difference between the first connecting pipe 802 and the suction hole 602 is as large as possible, so that there is enough negative pressure in the sliding cavity 9012 to push the ejector 9014, and when the ejector 9014 lifts up the molded model, the water level rises to below the first connecting pipe 802, and the suction pump 801 is turned off, and the mold box 601 is The water will flow into the water inlet pipe 702 due to the effect of gravity and re-enter the water tank 701 for next use. The volume of the water tank 701 is much larger than the volume of the mold box 601, so the water temperature of the water tank 701 will not change much and can be used repeatedly. When the water in the mold box 601 drops, the negative pressure in the slide cavity 9012 will also decrease, so the return spring 9015 will reset the push rod 9014. The movement of the push rod 9014 is driven by the negative pressure achieved by the water level height inside the mold box 601, so that no additional driving force is required to drive the push rod 9014 to move, which is more convenient to use and solves energy consumption.

[0044] like Figure 5 , Figure 8 and Fig. 9As shown, in some embodiments, a gap is left between the inner wall of the mold box 601 and the die 603, that is, when the water level inside the mold box 601 rises, the water in the mold box 601 can not only contact the bottom surface of the die 603, but also contact the side surface of the die 603, further improving the cooling effect.

[0045] like Figure 2 , Figure 3 and Fig. 9 As shown, in some embodiments, a floating plate 10 is vertically slidably installed on the inner wall of the mold box 601 connecting to the first connecting tube 802, which is used to block the connection between the mold box 601 and the first connecting tube 802, and a gap is left between the floating plate 10 and the die 603. That is to say, when the water level in the mold box 601 is about to be higher than the first connecting tube 802, the floating plate 10 will block the connection between the first connecting tube 802 and the mold box 601 due to the upward movement of the water level, thereby preventing the water level from continuing to rise and entering the first connecting tube 802.

[0046] like Figure 2 , Figure 7 and Fig. 9 As shown, in some embodiments, a sliding plate 11 is vertically slidably installed on the side of the mold box 601, and a driving rod 12 is horizontally slidably installed on the side of the sliding plate 11 away from the mold box 601. The free end of the driving rod 12 is constructed with a convex rod 15, and the horizontal end of the convex rod 15 is constructed with a lifting plate 16. The bottom end of the lifting plate 16 is flush with the top of the die 603. A driving component 17 for driving the sliding plate 11 and the lifting plate 16 to move is installed on the water tank 701. That is to say, after the ejector rod 9014 ejects the formed model, a gap is left between the formed model and the open end of the die 603. At this time, the driving component 17 is used to move the lifting plate 16 toward the middle of the die 603, so that it is located between the die 603 and the formed mold. Then the driving component 17 drives the sliding plate 11 to move upward, thereby removing the forming mold located in the die 603 from the die 603, thereby making it more convenient for the staff to remove the formed model.

[0047] like Figure 8As shown, in some embodiments, a connecting spring 13 is installed between the driving rod 12 and the sliding plate 11, a spring telescopic rod 14 is installed between the top of the sliding plate 11 and one side of the mold box 601, and the driving component 17 acts on the upper pressure plate 5. When the upper pressure plate 5 moves from bottom to top, the driving component 17 drives the lifting thin plate 16 to move in the direction close to the connecting rod 4 and then move upward. That is to say, when the upper pressure plate 5 moves upward and the push rod 9014 lifts the formed mold, the upper pressure plate 5 continues to move upward, thereby cooperating with the driving component 17 to realize the lifting of the thin plate 16. Move in the direction close to the connecting rod 4 and then move upward, and no additional driving force is required to drive the lifting thin plate 16 to move.

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the driving assembly 17 includes a rectangular frame plate 1701 vertically slidably mounted on the water tank 701, a convex frame 1702 is vertically constructed on the inner circumference of the rectangular frame plate 1701, a forcing slope 1703 is constructed at the bottom end of the convex rod 15, the convex frame 1702 is used to contact the forcing slope 1703, the convex rod 15 is located at the highest end of the forcing slope 1703 and is horizontally constructed with a forcing plate 1704 for contacting the convex frame 1702, a forcing rod 1705 is vertically constructed on the rectangular frame plate 1701, and a contact plate 1706 is horizontally constructed on one side of the forcing rod 1705, and the contact plate 1706 is located above the upper pressing plate 5. After the blister is completed, the upper pressing plate 5 moves upward for a distance and the upper pressing plate 5 has not yet contacted the contact plate 1706. Contact, when the subsequent push rod 9014 lifts the formed model, the upper pressure plate 5 continues to move upward, so that the upper pressure plate 5 contacts the bottom of the contact plate 1706, thereby driving the contact plate 1706 to move upward, and the upper pressure plate 5 moves upward to force the forcing rod 1705 to move upward, thereby driving the rectangular frame plate 1701 to move upward, and then the convex frame 1702 will contact the forcing inclined surface 1703 to force multiple lifting thin plates 16 to move closer to the center of the die 603, so as to be located between the die 603 and the formed model, at this time, as the upper pressure plate 5 continues to move upward, the convex frame 1702 will contact the forcing plate 1704, thereby causing the sliding plate 11 to move upward, so that the lifting thin plate 16 continues to move upward to take out the formed model.

[0049] Working principle: First, the thermoplastic material is heated by the heating component, and then the heated thermoplastic material is placed on the open end of the die 603 by the conveying component, and then the upper pressing plate 5 is moved downward by the hydraulic cylinder 3 to hold the open end of the die 603. At this time, the upper pressing plate 5 and the die 603 hold the thermoplastic material, and then the suction pump 801 is started, the first connecting pipe 802 will suck air, and the second connecting pipe 803 will release air, so the suction force generated by the first connecting pipe 802 will suck the thermoplastic material located at the end face of the die 603 into the die 603, and the second connecting pipe 803 will push the thermoplastic material in the die 603 into the die 603, so that After the blister is completed, the thermoplastic material will be attached to the concave mold 603 and the air suction hole 602 will be blocked. Then the upper pressing plate 5 moves upward for a distance. At this time, the upper pressing plate 5 does not contact the contact plate 1706 after moving. At this time, negative pressure will be generated in the air inlet pipe, so that the water in the water storage tank 701 is pumped into the water inlet pipe 702. The water level in the water inlet pipe 702 rises, so that the buoyancy member 9023 floats upward until the blocking block 9024 blocks the air suction hole 602. Because the water inlet pipe 702 is connected to the water delivery pipe 703, the water will enter the water delivery pipe 703 and then enter the mold box 601. When the water level inside the mold box 601 is higher than the blocking block 90 At 24:00, the water level continues to rise, thereby submerging the blocking block 9024. At this time, part of the water will enter the drainage hole 9016, thereby the water will enter the sliding cavity 9012. As the water level in the sliding cavity 9012 rises, the sliding block 9013 is pushed up, and then the push rod 9014 passes through the suction hole 602 to push up the cooled molded model. When the floating plate 10 blocks the connection between the first connecting pipe 802 and the mold box 601, the suction pump 801 is turned off at this time, and the water in the mold box 601 will flow into the water inlet pipe 702 due to gravity and re-enter the water tank 701 for next use, and finally the upper pressing plate 5 continues to move upward, so that the upper pressing plate 5 contacts the bottom of the contact plate 1706, thereby driving the contact plate 1706 to move upward, and the upper pressing plate 5 moves upward so that the forcing rod 1705 moves upward, thereby driving the rectangular frame plate 1701 to move upward, and then the convex frame 1702 will contact the forcing inclined surface 1703 to force the multiple lifting thin plates 16 to move closer to the center of the die 603, so as to be located between the die 603 and the formed model, at this time, as the upper pressing plate 5 continues to move upward, the convex frame 1702 will contact the forcing plate 1704, thereby moving the sliding plate 11 upward, so that the lifting thin plates 16 continue to move upward to take out the formed model.
