Description

Technical Field

[0001] This invention relates to the field of refrigerator liner vacuum forming technology, specifically to a vacuum forming device for preparing refrigerator liners. Background Technology

[0002] The refrigerator liner is one of the core components of a refrigerator, mainly responsible for heat preservation, sealing, and supporting the internal structure. Its production widely adopts the vacuum forming process. Vacuum forming of refrigerator liners is a manufacturing process in which plastic sheets are heated and softened, then adsorbed onto the surface of a mold using vacuum negative pressure, and finally cooled and shaped to form a specific shape. This process has become the main choice for manufacturing large thin-walled plastic parts due to its high efficiency and low cost.

[0003] Currently, during the thermoforming process of refrigerator liners, operators need to place the plastic sheet into the thermoforming device. After the plastic sheet is inside, the operator needs to use a clamping device to fix it inside the device to prevent air leakage during the thermoforming process. The thermoforming device needs to heat the plastic sheet first before thermoforming it. After heating, the plastic sheet is thermoformed. After thermoforming, the operator needs to remove it. This manual loading and unloading method results in slow efficiency in the thermoforming process of refrigerator liners, and the operator is also prone to getting burned by residual air from the plastic sheet during unloading.

[0017] The present invention has the following beneficial effects:

[0018] This invention starts by activating an air pump. The air pump generates gas that inflates a plastic sheet, improving its flexibility and allowing it to better adhere to the mold surface, thus enhancing the quality of the refrigerator liner's vacuum forming. After the plastic sheet inflates, a hydraulic rod is activated to move a sealing plate upwards. As the sealing plate moves upwards, it pushes the mold into the interior of the plastic sheet. Once the mold is inside, the air pump stops, and a vacuum pump is activated. The suction force generated by the vacuum pump enters the interior of the plastic sheet through the mold, quickly expelling the air inside. Under the action of the vacuum pump, the plastic sheet adheres to the surface of the mold, completing the vacuum forming of the refrigerator liner. During the vacuum forming process, the sealing plate seals the vacuum forming frame, ensuring stable suction from the vacuum pump within the plastic sheet, further improving the quality of the refrigerator liner's vacuum forming. After the refrigerator liner is vacuum-formed, the hydraulic rod is activated again to move the sealing plate downwards. The sealing plate pulls the mold downwards, separating it from the refrigerator liner, completing the demolding process and improving the convenience of the refrigerator liner vacuum forming operation.

[0019] In this invention, the linkage plate moves by connecting the limiting plate and the electric push rod, which in turn pushes the suction frame to move. After the suction frame moves above the heating device, the electric push rod is activated to push the suction frame downwards. When the suction frame contacts the top of the plastic sheet, the suction pump is activated to begin operation. The suction force generated by the suction pump during operation enters the interior of the transfer hose through the adapter pipe. After the transfer hose transmits the suction force to the interior of the suction frame, the suction frame can then adsorb the plastic sheet below it. After the plastic sheet is fixed, the electric slide transports the plastic sheet to the top of the blister pack. The electric push rod places the plastic sheet on the top of the suction frame. At this time, the suction frame uses the pressure of the electric push rod to press and fix the plastic sheet to the top of the blister pack, improving the sealing between the plastic sheet and the blister pack. The suction frame is used to transfer the plastic sheet, improving the convenience of the plastic sheet during the blister pack operation. The plastic sheet is removed from the top of the heating device using the suction frame, without requiring manual approach to the plastic sheet, thus avoiding burns to the operator.

[0020] When the cutting component of this invention cuts the plastic sheet, the cut plastic waste falls into the inside of the recycling rack for centralized recycling. When the electric rod moves upward, it pulls two pusher plates closer together via an inclined plate. As the pusher plates move closer together, they move to below the lifting plate, where the triangular plates at the top of the pusher plates contact each other. The waste cut by the cutting component slides down through the triangular plates to both ends of the inside of the recycling rack. After the plastic sheet is cut, the worker can remove the finished refrigerator liner, improving the convenience of refrigerator liner processing. When the electric rod pushes the lifting plate downward, it pushes the pusher plates away from each other via an inclined plate. As the pusher plates move, they push the waste in the recycling rack into the inside of the conveyor rack for the worker to recycle.

[0021] This invention activates a robotic arm to operate a cutting device to cut a plastic sheet. The robotic arm adjusts the position of the cutting device to better trim the refrigerator liner. When the electric moving frame slides automatically on the surface of the slide plate, it adjusts the position of the cutting device so that the cutting device can better cut around the refrigerator liner.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 As shown, the present invention is a thermoforming device for preparing refrigerator liners, including a base plate 1, a heating device 2 provided on the top of the base plate 1, a support plate 4 fixedly connected to the top of the base plate 1, a slide rail 3 fixedly connected to the upper surface of the support plate 4, and a thermoforming component 5 provided on the top of the base plate 1.

[0038] The vacuum forming component 5 includes a vacuum forming frame 10. The bottom of the vacuum forming frame 10 is fixedly connected to the top of the base plate 1. A sealing plate 14 is slidably connected to the inner wall of the vacuum forming frame 10. A mold 12 is fixedly connected to the top of the sealing plate 14. An air pump 13 is connected to the top of the inner wall of the mold 12. The bottom of the air pump 13 is fixedly connected to the top of the sealing plate 14. A hose 15 is connected to the air inlet end of the air pump 13. The end of the hose 15 away from the air pump 13 passes through the sealing plate 14 and extends to the outer end of the vacuum forming frame 10. A vacuum pump 11 is fixedly connected to the top of the base plate 1. A connecting hose 17 is connected to the working end of the vacuum pump 11. The end of the connecting hose 17 away from the vacuum pump 11 is fixedly connected to the bottom of the sealing plate 14. A hydraulic rod 16 is fixedly connected to the bottom of the sealing plate 14. The bottom of the hydraulic rod 16 is fixedly connected to the bottom of the inner wall of the base plate 1. The gas generated by the air pump 13 blows the vacuum forming frame 10. The plastic sheet is inflated. After the plastic sheet is inflated, its toughness is improved, allowing it to better adhere to the surface of the mold 12 and improving the quality of the vacuum forming of the refrigerator liner. After the plastic sheet is inflated, the hydraulic rod 16 is activated to push the sealing plate 14 upward. When the sealing plate 14 moves upward, it pushes the mold 12 into the interior of the plastic sheet. After the mold 12 enters the interior of the plastic sheet, the air pump 13 stops working, and the vacuum pump 11 is activated. The suction force generated by the vacuum pump 11 enters the interior of the plastic sheet through the mold 12, quickly expelling the air inside the plastic sheet. At this time, the plastic sheet adheres to the surface of the mold 12 under the action of the vacuum pump 11, thus completing the vacuum forming of the refrigerator liner. A transfer component 6 is provided above the base plate 1, a support component 7 is provided at the top of the base plate 1, and a cutting component 8 is provided above the support component 7.

[0039] The top of the mold 12 is horizontally positioned with the top of the blister pack 10, the upper surface of the mold 12 is in contact with the inner wall of the blister pack 10, the surface of the mold 12 is provided with micro blister holes, and the top of the connecting hose 17 is connected to the mold 12.

[0040] The transfer component 6 includes an electric slide 22, the inner wall of which is slidably connected to the surface of the slide rail 3. A stabilizing plate 20 is slidably connected to the inner wall of the slide rail 3. The electric slide 22 is fixedly connected to the surface of the stabilizing plate 20. A connecting plate 24 is fixedly connected to the surface of the stabilizing plate 20. A limiting plate 21 is fixedly connected to the surface of the connecting plate 24. An adsorption pump 25 is installed at the top of the limiting plate 21. A transfer pipe 23 is fixedly connected to the surface of the connecting plate 24. The air inlet of the adsorption pump 25 is connected to the transfer pipe 23. An electric push rod 26 is fixedly connected to the bottom of the limiting plate 21. A bracket 28 is fixedly connected to the bottom of the electric push rod 26. An adsorption frame 27 is fixedly connected to the bottom of the bracket 28. A transmission hose 29 is connected to the bottom of the transfer pipe 23. The bottom of the transmission hose 29 is connected to the top of the adsorption frame 27. When the connecting plate 24 moves, it pushes the adsorption frame 27 to move through the connection between the limiting plate 21 and the electric push rod 26. After the suction rack 27 moves above the heating device 2, the electric push rod 26 is activated to push the suction rack 27 downward. When the suction rack 27 contacts the top of the plastic sheet, the suction pump 25 is activated to start operation. The suction force generated by the suction pump 25 during operation enters the interior of the transfer hose 29 through the adapter pipe 23. After the transfer hose 29 transmits the suction force to the interior of the suction rack 27, the suction rack 27 can then use the suction force to adsorb the plastic sheet below the suction rack 27. After the plastic sheet is fixed, the plastic sheet is transferred to the top of the blister pack 10 through the electric slide 22. The electric push rod 26 is used to place the plastic sheet on the top of the suction rack 27. At this time, the suction rack 27 uses the pressure of the electric push rod 26 to squeeze and fix the plastic sheet to the top of the blister pack 10, improving the sealing between the plastic sheet and the blister pack 10. The suction rack 27 is used to transfer the plastic sheet, improving the convenience of the plastic sheet during the blister pack operation.

[0041] There are two stabilizing plates 20, which are symmetrically arranged with the base plate 1 as the center. There are four electric slides 22, which are arranged in two groups, and each group has two slides. The two electric slides 22 are located at the outer end of the stabilizing plate 20.

[0042] The end of the adapter pipe 23 passes through the connecting plate 24 and extends to the outer end of the connecting plate 24. The adapter pipe 23 is symmetrically arranged with the adsorption pump 25 as the center. The adsorption rack 27 is located above the blister rack 10.

[0043] The supporting component 7 includes a recycling rack 30, the bottom of which is fixedly connected to the top of the base plate 1. A placement plate 32 is fixedly connected to the top of the recycling rack 30. A conveyor rack 31 is connected to the surface of the recycling rack 30. An electric rod 37 is fixedly connected to the bottom of the inner wall of the recycling rack 30. A lifting plate 33 is fixedly connected to the top of the electric rod 37. An inclined plate 38 is hinged to the upper surface of the electric rod 37. A pusher plate 35 is hinged to the end of the inclined plate 38 away from the electric rod 37. A triangular plate 36 is fixedly connected to the top of the pusher plate 35. A sliding plate 34 is fixedly connected to the inner wall of the recycling rack 30. When the cutting component 8 cuts the plastic sheet, it cuts the bottom... The incoming plastic waste will fall into the inside of the recycling rack 30 for centralized recycling. When the electric rod 37 moves upward, it will pull the two pusher plates 35 closer together via the inclined plate 38. When the pusher plates 35 move closer together, they will move to the bottom of the lifting plate 33. The triangular plates 36 on the top of the pusher plates 35 will contact each other. The waste cut by the cutting component 8 will slide down through the triangular plates 36 to both ends of the inside of the recycling rack 30. After the plastic plate is cut, the worker can take out the processed refrigerator liner, improving the convenience of refrigerator liner processing.

[0044] There are two pusher plates 35, which are symmetrically arranged around the electric rod 37. There are four triangular plates 36, which are arranged in two groups, with two in each group. The two groups of triangular plates 36 are symmetrically arranged around the pusher plate 35. The inner wall of the pusher plate 35 is slidably connected to the surface of the slide plate 34.

[0045] The surface of the pusher plate 35 is in contact with the inner wall of the recycling rack 30. There are two inclined plates 38, which are symmetrically arranged with the electric rod 37 as the center. The ends of the two inclined plates 38 that are away from the electric rod 37 are arranged far apart from each other.

[0046] The cutting component 8 includes a mounting bracket 40, the bottom of which is fixedly connected to the top of a support plate 4. A cylindrical frame 41 is fixedly connected to the top of the mounting bracket 40. An electric telescopic rod 42 is fixedly connected to the top of the inner wall of the cylindrical frame 41. A sliding plate 43 is fixedly connected to the bottom of the electric telescopic rod 42. An electric moving frame 46 is slidably connected to the surface of the sliding plate 43. A robotic arm 45 is mounted on the surface of the electric moving frame 46. A cutting device 44 is fixedly connected to the end of the robotic arm 45 away from the electric moving frame 46. An extrusion plate 47 is fixedly connected to the bottom of the sliding plate 43. When the robotic arm 45 is activated, the cutting device 44 is operated to cut the plastic sheet. The position of the cutting device 44 is adjusted by the robotic arm 45 so that it can better trim the refrigerator liner. When the electric moving frame 46 slides automatically on the surface of the sliding plate 43, it will adjust the position of the cutting device 44 so that the cutting device 44 can better cut the circumference of the refrigerator liner.

[0047] The telescopic end of the electric telescopic rod 42 extends to the bottom outer end of the cylindrical frame 41, the mounting frame 40 is located above the chute frame 3, and the extrusion plate 47 is located above the recycling frame 30.

[0048] In use, the plastic sheet used for the refrigerator liner is placed on top of the heating device 2. The heating device 2 is used to heat and soften the plastic sheet. After the plastic sheet is softened, the transfer component 6 is started. During operation, the transfer component 6 transfers the plastic sheet from the top of the heating device 2 to the top of the vacuum forming frame 10 and presses and fixes it on the top of the vacuum forming frame 10. At this time, the air pump 13 is started. The air generated by the air pump 13 blows the plastic sheet to inflate it. After the plastic sheet is inflated, its toughness will be improved, so that the plastic sheet can better fit the surface of the mold 12, improving the vacuum forming quality of the refrigerator liner. After the plastic sheet is inflated, the hydraulic rod 16 is activated to push the sealing plate 14 upward. When the sealing plate 14 moves upward, it pushes the mold 12 into the interior of the plastic sheet. After entering the interior of the plastic sheet, the air pump 13 stops operating, and the vacuum pump 11 starts operating. The suction force generated by the vacuum pump 11 enters the interior of the plastic sheet through the mold 12, quickly expelling the air inside the plastic sheet. At this time, the plastic sheet will adhere to the surface of the mold 12 under the action of the vacuum pump 11, thus completing the vacuum forming operation of the refrigerator liner. When the mold 12 is performing vacuum forming on the plastic sheet, the sealing plate 14 will seal the vacuum forming frame 10, so that the suction force of the vacuum pump will operate stably inside the plastic sheet, further improving the vacuum forming quality of the refrigerator liner. After the refrigerator liner is vacuum formed, when the hydraulic rod 16 is activated to push the sealing plate 14 downward, the sealing plate 14 will pull the mold 12 downward to separate from the refrigerator liner, completing the demolding process and improving the convenience of the refrigerator liner vacuum forming operation.

[0049] After the heating device 2 completes the heating of the plastic sheet, the electric slide 22 is activated to move on the surface of the slide frame 3. During this movement, the electric slide 22 pushes the stabilizing plate 20 to move inside the slide frame 3. The stabilizing plate 20 supports the electric slide 22 and the connecting plate 24, improving their stability during operation. As the connecting plate 24 moves, it pushes the suction frame 27 to move through the connection between the limiting plate 21 and the electric push rod 26. After the suction frame 27 moves above the heating device 2, the electric push rod 26 is activated to push the suction frame 27 downwards. When the suction frame 27 contacts the top of the plastic sheet, the suction pump 25 is activated to begin operation. The suction generated by the suction pump 25 during operation enters the transmission hose 29 through the adapter 23. Inside the device, the transfer hose 29 transmits suction to the inside of the suction rack 27. The suction rack 27 can then use suction to attach the plastic sheet to the bottom of the suction rack 27. After the plastic sheet is fixed, the electric slide 22 transfers the plastic sheet to the top of the blister pack 10. The electric push rod 26 places the plastic sheet on the top of the suction rack 27. At this time, the suction rack 27 uses the pressure of the electric push rod 26 to press and fix the plastic sheet to the top of the blister pack 10, improving the sealing between the plastic sheet and the blister pack 10. The suction rack 27 is used to transfer the plastic sheet, improving the convenience of the plastic sheet during the blister pack operation. The plastic sheet is removed from the top of the heating device 2 through the suction rack 27. During this process, no one needs to approach the plastic sheet, avoiding burns to the operator.

[0050] After the plastic sheet completes the vacuum forming process at the top of the vacuum forming frame 10, it is transferred to the top of the placement plate 32 via the suction frame 27. At this point, when the electric lever 37 is activated to push the lifting plate 33 upwards, the lifting plate 33 moves to the inside of the plastic sheet and contacts its inner wall, thus fixing the plastic sheet above the recycling rack 30. When the cutting component 8 cuts the plastic sheet, the cut plastic waste falls into the recycling rack 30 for centralized recycling. As the electric lever 37 moves upwards, it pulls the two pusher plates 35 closer together via the inclined plate 38. When the pusher plates 35 move closer to each other, they will move to the bottom of the lifting plate 33. The triangular plates 36 on the top of the pusher plates 35 will contact each other. The waste material cut off by the cutting component 8 will slide down through the triangular plates 36 to the two ends of the inside of the recycling rack 30. After the plastic sheet is cut, the worker can take out the processed refrigerator liner, which improves the convenience of refrigerator liner processing. When the electric rod 37 pushes the lifting plate 33 downward, the electric rod 37 pushes the pusher plates 35 away from each other through the inclined plate 38. When the pusher plates 35 move, they will push the waste material in the recycling rack 30 into the inside of the transfer rack 31 so that the worker can recycle the plastic waste.

[0051] After the lifting plate 33 secures the plastic sheet, the electric telescopic rod 42 moves downward. The electric telescopic rod 42 pushes the extrusion plate 47 downward via the sliding plate 43. As the extrusion plate 47 moves downward, it contacts the top of the plastic sheet, thus securing the plastic sheet to the top of the lifting plate 33. This improves the stability of the plastic sheet during cutting and repair, preventing tilting of the refrigerator liner during cutting. After securing the plastic sheet, the robotic arm 45 operates the cutting device 44 to cut the plastic sheet. The robotic arm 45 adjusts the position of the cutting device 44 to better trim the refrigerator liner. As the electric moving frame 46 automatically slides on the surface of the sliding plate 43, it adjusts the position of the cutting device 44, allowing it to better cut around the perimeter of the refrigerator liner.
