Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing technology, specifically to a refrigerator liner forming device and a refrigerator production line. Background Technology

[0002] Currently, the process of forming refrigerator liners involves heating raw plastic granules and additives using a three-roller machine to form sheets at high temperatures. After a long cooling distance, the sheets are automatically cut to specific dimensions. These sheets are then picked up and stacked by robotic arms, and subsequently transported manually to a vacuum forming machine. The robotic arms pick up the cut sheets, and the liner undergoes a preheating, forming, and punching process to complete the liner forming. Notably, refrigerator liners and freezer liners require separate forming, necessitating two sets of molds for the liner forming process.

[0003] However, in the box liner molding process, the plastic raw materials undergo a long cooling distance after being heated and molded into sheets, requiring a large area. The vacuum forming process then requires reheating, resulting in two heating cycles and potential resource waste. Furthermore, the cutting process generates numerous scraps, which, although remelted through secondary heating, still result in significant resource waste. In addition, box liner molding involves automated sheet cutting, robotic arm picking, and manual sheet transportation, all of which pose safety hazards. Therefore, box liner molding suffers from high mold costs, low material utilization, high energy consumption, large footprint, and complex processes. Utility Model Content

Such spatially relative terms can be used to describe a position as

[0059] The box body forming is formed by heating the raw material plastic particles and additives through a three-roll device to form a plate, the plate has a high temperature, and after a long distance cooling, the subsequent automatic cutting forms a plate with a certain size, which is picked up and stacked by a mechanical arm, and then the cut plate is transported to a vacuum forming device by manual operation. The mechanical arm picks up the cut plate, and the box body forming is completed through the preheating-forming-punching process. Among them, the refrigerator cold storage box body and the freezer box body need to be formed separately, so it can be seen that the box body forming needs two sets of molds.

[0060] Among them, vacuum forming is a plastic refrigerator process. The main principle of vacuum forming is to heat the flat plastic hard sheet to soften, and then use negative pressure to adsorb on the surface of the mold, and after cooling, it is a kind of technical process. In the forming process of the refrigerator liner, vacuum forming is generally used to manufacture the refrigerator liner.

[0061] However, in the process of box body forming, the plastic raw material is cooled after being heated and formed into a plate, which requires a large space, and needs to be heated again for vacuum forming, that is, it needs to be heated twice, which is easy to cause waste of resources, and at the same time, the plate after forming will have a lot of edge scraps in the cutting process. Although these edge scraps can be melted again to form a plate through secondary heating in the subsequent process, a large amount of resources is also wasted in the whole process.

[0062] To address the aforementioned technical problems, this application provides a refrigerator liner forming apparatus to solve the problems of high mold costs, low material utilization, high energy consumption, large footprint, and complex processes in existing refrigerator liner forming methods.

[0063] In terms of overall design, such as Figures 1-6 As shown, the refrigerator liner forming device 1000 includes a support plate 11 and a pressing member 50. The support plate 11 is used to receive the sheet metal 300 and has a punching hole 111. The pressing member 50 is movably disposed on one side of the support plate 11 along a first direction and is used to press the sheet metal 300 against the support plate 11. Along the first direction, a first slider 20 is movably disposed on the other side of the support plate 11. A punch assembly 30 is disposed on the first slider 20 and is adapted to the punching hole 111. The punch assembly 30 includes a first punch 31 and a second punch 32 arranged sequentially along a second direction, which is perpendicular to the first direction. The first punch 31 is connected to the first slider 20, and the second punch 32 is movably disposed on the first slider 20 along the first direction. The second punch 32 has a first working position and a second working position.

[0064] Specifically, the mold with a segmented punch works in conjunction with the pressure plate 50 and the first slider 20 to stamp and vacuum-form the newly formed sheet metal 300 on the support plate 11, thereby enabling the molding and production of refrigerator and freezer liners. Combining the segmented punch with traditional stamping and vacuum forming processes reduces mold investment costs, thus helping to reduce the footprint of the refrigerator liner molding device 1000. Furthermore, it allows for the selective production of either refrigerator or freezer liners, enriching the manufacturing capabilities of the refrigerator liner molding device 1000 and improving its applicability.

[0065] In addition, the support plate can directly support the newly formed sheet 300. Since the newly formed sheet 300 has residual heat, it can be stamped and vacuum-formed before it cools down. This helps to reduce the cooling time and reheating time of the sheet 300, improves material utilization, reduces energy consumption, and reduces resource waste.

[0066] It is necessary to understand that, such as Figure 1 and Figure 4As shown, the refrigerator liner forming device 1000 comprises a forming mechanism 100 and a conveying mechanism 200, wherein the conveying mechanism 200 can make the plate material 300 and convey the plate material 300 to the forming mechanism 100, at this time, the plate material 300 output by the conveying mechanism 200 is the just-formed plate material 300, and the plate material 300 has residual heat. In the embodiment, the forming mechanism 100 comprises a first rack 10, a pressing piece 50 and a punch assembly 30. The first rack 10 comprises a first die seat 12 and a second die seat 13, and the first die seat 12 and the second die seat 13 are arranged in a first direction. Optionally, the first die seat 12 is arranged below the second die seat 13, the first die seat 12 and the second die seat 13 are connected through four guide columns 14, and a supporting plate 11 is arranged between the first die seat 12 and the second die seat 13. The supporting plate 11 is connected with the four guide columns 14, and a stamping hole 111 is arranged on the supporting plate 11, which can be penetrated by the punch assembly 30.

[0067] In the embodiment, the first rack 10 further comprises a first sliding block 20 and a second sliding block 40, wherein the first sliding block 20 is movably arranged between the first die seat 12 and the supporting plate 11, the second sliding block 40 is movably arranged between the second die seat 13 and the supporting plate 11, and the first sliding block 20 and the second sliding block 40 are respectively slidably connected with the four guide columns 14. The first sliding block 20 and the second sliding block 40 can move in the vertical direction under the action of an external force. Optionally, the first sliding block 20 and the second sliding block 40 can move towards or away from each other.

[0068] It should be noted that the movement of the first sliding block 20 can be realized by a driving device arranged on the first die seat 12. Optionally, the driving device is arranged as a hydraulic pump or a gas pump and the like. Of course, the driving device can also be arranged at other positions, such as the outside of the supporting plate 11 or the first rack 10, as long as it can realize the movement of the first sliding block 20. Moreover, the driving device of the second sliding block 40 is the same as or different from that of the first sliding block 20, as long as it can realize the movement of the second sliding block 40.

[0069] It needs to be further understood that the second slider 40 is provided with a pressing piece 50, and the pressing piece 50 is located on the surface of the second slider 40 facing the first slider 20. In the embodiment, the pressing piece 50 is fixedly arranged below the second slider 40, and the pressing piece 50 can press the plate 300 on the supporting plate 11 with the movement of the second slider 40, thereby fixing the plate 300 on the supporting plate 11, which helps to avoid the movement of the plate 300 when the punch assembly 30 works. At the same time, the second slider 40 is provided with a first avoiding hole 41, and the pressing piece 50 is provided with a second avoiding hole 51, and the first avoiding hole 41 and the second avoiding hole 51 are matched with the punch assembly 30. At this time, the punch assembly 30 can pass through the stamping hole 111, the second avoiding hole 51 and the first avoiding hole 41 in turn with the movement of the first slider 20.

[0070] In the embodiment, the first slider 20 is provided with a first punch 31 and a second punch 32, and the first punch 31 and the second punch 32 are arranged in the second direction in sequence. The second direction is perpendicular to the first direction, and the second direction is the same as the conveying direction of the plate 300, that is, the second direction is the horizontal direction. At the same time, the first punch 31 is fixedly connected with the first slider 20, and the second punch 32 is movably arranged on the first slider 20 in the vertical direction. The second punch 32 has a first working position and a second working position. The first punch 31 is connected with the first slider 20 through a screw, and when the second punch 32 is in the first working position, the top end of the second punch 32 and the top end of the first punch 31 are located in the same horizontal plane. At this time, the punch assembly 30 can move with the first slider 20 to make the plate 300 into a refrigeration tank. When the second punch 32 is in the second working position, the top end of the second punch 32 and the top end of the first punch 31 are arranged in the vertical direction. At this time, the punch assembly 30 can move with the first slider 20 to make the plate 300 into a freezing tank. Since the position of the second punch 32 is adjustable, the freezing tank compressor chamber volume is adjustable, which helps to further improve the applicability of the refrigerator tank forming device 1000.

[0071] It needs to be further understood that in the embodiment, the first punch 31 is connected with the first slider 20 through a screw. An avoiding cavity 21 is formed in the first slider 20, which can provide a moving space for the second punch 32, and ensure the applicability of the punch assembly 30. At the same time, the movement of the second punch 32 can be implemented by a gas cylinder or a hydraulic cylinder, which will not be described in detail here.

[0072] Further, the first punch 31 is provided with an adsorption structure 301 on the opposite sides in the third direction, and the adsorption structure 301 is provided with a vacuum hole 302. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0073] And / or, the second punch 32 is provided with an adsorption structure 301 on each of the opposite sides in the third direction, and the adsorption structure 301 is provided with a vacuum hole 302, the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0074] Specifically, by providing the adsorption structure 301 on the side of the first punch 31 and the second punch 32, the reinforcing rib, the embedded box and other structures can be formed by the plastic suction process during the preparation of the tank. At the same time, by providing the vacuum hole 302 on the adsorption structure 301, the normal implementation of the plastic suction process can be effectively guaranteed, and the thickness of the reinforcing rib or the embedded box of the tank can be ensured to be uniform, that is, it is helpful to guarantee the effective combination of traditional stamping and plastic suction, improve the quality of the tank after forming, and reduce the difficulty of forming the tank structure.

[0075] It should be understood that the adsorption structure 301 is provided on each of the opposite sides of the first punch 31 and the second punch 32 in the third direction, and the adsorption structure 301 is used to prepare the reinforcing rib of the tank. In this embodiment, the third direction is a horizontal direction and perpendicular to the second direction. Specifically, the adsorption structure 301 is a structure that the first punch 31 or the second punch 32 is recessed inwardly in the third direction, that is, a groove is formed on each side of the first punch 31 and the second punch 32, and the groove is arranged in the vertical direction. At this time, the groove is the adsorption structure 301. At the same time, the vacuum hole 302 is arranged at the bottom of the groove.

[0076] In addition, since the top end of the second punch 32 is arranged in the vertical direction with the top end of the first punch 31 when the second punch 32 is in the second working position, at this time, the top end of the second punch 32 and the top end of the first punch 31 form a height difference in the height direction, which is easy to cause uneven distribution of the material at the top of the tank during stamping. In this embodiment, a plurality of vacuum holes 302 are arranged on the top end face of the second punch 32 to guarantee that the height forming of the refrigerator tank has better manufacturing effect, which is helpful to further guarantee the quality of the refrigerator tank after forming.

[0077] Further, the first punch 31 is respectively provided with a temperature sensor and a temperature compensation element, and / or the second punch 32 is respectively provided with a temperature sensor and a temperature compensation element.

[0078] Specifically, by setting the temperature sensor, different optimal forming temperatures can be set for different plastic materials, and by setting the temperature compensation element, the temperature sensor is used to realize self-compensation of the mold temperature, thereby improving the forming effect of the plastic. Moreover, since the punch assembly 30 uses the waste heat of the plate 300 during stamping and plastic suction, the temperature sensor and the temperature compensation element are used to further improve the utilization rate of energy.

[0079] It needs to be understood that the temperature sensor can detect the temperature of the sheet 300, and the temperature compensation member can increase the temperature of the sheet 300 by heating the mold. Of course, the temperature compensation member can also have a cooling function to adjust the temperature of the sheet 300. The temperature sensor and the temperature compensation member can use existing devices and can be directly used by purchase, which helps to reduce the manufacturing difficulty and the investment cost required for manufacturing the refrigerator liner forming device 1000. Details are not described here.

[0080] Further, the refrigerator liner forming device 1000 further comprises a cutting member 60, the cutting member 60 is arranged on the supporting plate 11, the cutting member 60 has a receiving groove 61, the pressing member 50 can be accommodated in the receiving groove 61, and the pressing member 50 is matched with the receiving groove 61.

[0081] Specifically, by arranging the cutting member 60, the sheet 300 can be accurately cut, and then cooperated with the pressing member 50 and the punch assembly 30 for manufacturing, which helps to reduce the scrap in the cutting process of the sheet 300, and then helps to reduce the energy required for secondary heating and melting, and helps to improve the utilization rate of resources.

[0082] It needs to be understood that the cutting member 60 is arranged on the supporting plate 11, in the embodiment, the cutting member 60 is arranged on the surface of the supporting plate 11 facing the second sliding block 40. Wherein, the cutting member 60 is arranged in a square frame structure, that is, the cutting member 60 has a receiving groove 61 in the inside, at the same time, the pressing member 50 is arranged in a square frame structure, the receiving groove 61 is matched and connected with the pressing member 50, and the pressing member 50 can be accommodated in the receiving groove 61 when the second sliding block 40 moves to the supporting plate 11. When the conveying mechanism 200 conveys the sheet 300 to the upper surface of the cutting member 60, the second sliding block 40 moves and makes the cutting member 60 enter the receiving groove 61, in this process, the pressing member 50 cooperates with the cutting member 60 to cut the sheet 300.

[0083] Further, the refrigerator liner forming device 1000 further comprises a limiting member 72, the limiting member 72 is arranged on the supporting plate 11 and located on the other side of the punching hole 111 along the second direction.

[0084] Specifically, by arranging the limiting member 72 on the supporting plate 11, the sheet 300 conveyed to the supporting plate 11 can be blocked to prevent over-conveying, which helps to avoid more scrap in the cutting process of the sheet 300, and helps to improve the utilization rate of the sheet 300. At the same time, it can also cooperate with the pressing member 50 and the cutting member 60 to ensure the accuracy of cutting the sheet 300.

[0085] It needs to be understood that, as Figure 1 and Figure 4As shown, the limiting piece 72 is arranged on the cutting plate, and the limiting piece 72 is in strip-shaped structure. An acting surface of the limiting piece 72 faces the plate 300, and the acting surface is located on the same vertical plane as one side surface of the cutting piece 60. Of course, in addition, the limiting piece 72 can be arranged in multiple, and is arranged in the third direction to ensure the contact effect with the plate 300.

[0086] Further, the refrigerator liner forming device 1000 further comprises a material guiding assembly 71, which is arranged on the supporting plate 11 and located on one side of the punching hole 111 in the second direction.

[0087] Specifically, the arrangement of the material guiding assembly 71 can receive the plate 300 in advance, so as to avoid the bending of the plate 300. At the same time, the material guiding assembly 71 can limit the position of the plate 300 in the third direction, so as to accurately move the plate 300 to the upper surface of the cutting piece 60.

[0088] It should be understood that the material guiding assembly 71 is arranged on the supporting plate 11, and the top of the material guiding assembly 71 is located on the same horizontal plane as the upper surface of the cutting piece 60. Optionally, a material guiding roller is arranged on the material guiding assembly 71, which can support and convey the plate 300 to ensure the conveying effect of the plate 300. Further, a limiting roller is arranged on the material guiding assembly 71, which is arranged in the third direction to enable clamping of the plate 300.

[0089] Further, the refrigerator liner forming device 1000 further comprises a conveying mechanism 200 for conveying the plate 300. The conveying mechanism 200 comprises a first roller 81 and a second roller 82, which are arranged in the first direction to roll the incoming material and form the plate 300, and the distance between the first roller 81 and the second roller 82 is adjustable.

[0090] Specifically, by arranging the conveying mechanism 200, the incoming material can be rolled into a plate-shaped structure by the rotation of the first roller 81 and the second roller 82 to form the plate 300. The distance between the first roller 81 and the second roller 82 is adjustable, so that the thickness of the plate 300 can be adjusted. The appropriate thickness of the plate 300 can meet the forming requirements of different liners and the required thickness standard. At this time, the plate 300 can be made into a refrigeration liner / cold storage liner through the process combining stamping and plastic suction.

[0091] It should be understood that, as shown in FIG. 6, the first roller 81 and the second roller 82 are arranged in the first direction to roll the incoming material and form the plate 300. Figure 2 and Figure 4As shown, the conveying mechanism 200 comprises a second rack 80, a first roller 81 and a second roller 82. The first roller 81 is rotatably arranged on the second rack 80, the second roller 82 is movably arranged on the second rack 80 in the vertical direction, and the second roller 82 is rotatable on the second rack 80.

The second roller 82 is arranged on the second rack 80 through a sliding block or a support, the sliding block or the support is movable on the second rack 80, and the second roller 82 is rotatable on the sliding block or the support.

[0092] It should be noted that, in addition to being arranged on the second rack 80 through a bearing, the first roller 81 can also adopt the same mounting structure as the second roller 82.
