Description

Technical Field

[0001] This utility model belongs to the field of inner liner processing technology, specifically, it relates to a pressing device for processing the inner liner of a freezer. Background Technology

[0002] A freezer is another name for a refrigerator or freezer cabinet. High-quality freezers use premium copper coils for all evaporator tubes, which are then processed into wide, irregular shapes. The stainless steel sheet has a smooth surface and uniform thickness; using an appropriate thickness ensures a long service life and a flat, sturdy appearance. A pressing device is required during the production of the freezer's inner liner. Application No.: CN202122821205.4 (Announcement No.: CN216227926U) discloses a special machine for pressing the inner liner of a freezer, including a base, a fixed frame welded to the bottom, a mold installed on the front of the fixed frame by bolts, two side extrusion mechanisms installed on the top of the base, each side extrusion mechanism including an electric telescopic rod, an extrusion plate installed at the output end of the electric telescopic rod, protective pads provided on one side and bottom of the extrusion plate, a forward and reverse motor installed on the front of the fixed frame by bolts, a threaded rod installed at the output end of the forward and reverse motor, a moving block threadedly connected to the threaded rod, a welding mechanism provided at the bottom of the moving block, and a fixed tube included in the welding mechanism; The extrusion plate of the aforementioned patented side extrusion mechanism is a "planar rigid structure" that can only be extruded from both sides. After the lateral relative movement presses the inner liner of the freezer together, it needs to move laterally back to back again to reset the extrusion plate for the next pressing. However, the back to back movement will rub against the inner liner of the freezer and may even cause the inner liner of the freezer to move, resulting in problems such as displacement and gaps after pressing. Utility Model Content

[0003] In view of this, the present invention provides a pressing device for processing the inner liner of a freezer. This device is used to solve the technical problem in the prior art that the "corner curvature" of the inner liner of a freezer cannot be adapted, resulting in loose pressing at the corners.

[0004] This utility model is implemented as follows: This utility model provides a pressing device for processing the inner liner of a freezer, including a base and a support rod. A module is fixedly installed on the support rod, and a movable block is provided below the module. It has a lifting mechanism for driving the movable block to move up and down, and a moving mechanism for driving a welding machine to move back and forth. Clamping mechanisms are provided on both sides of the movable block. The clamping mechanism includes a flap, a connector, a cylinder, a support plate, and a rotating shaft. The support plate is vertically mounted on the base and is located on both sides of the moving block. One end of the cylinder is rotatably connected to the outer wall of the support plate, and the other end is rotatably connected to one end of the connector. The other end of the connector is fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the support plate, and the flap is fixedly connected to the rotating shaft.

[0005] Based on the above technical solution, the pressing method for processing the inner liner of a freezer according to this utility model can be improved as follows: Furthermore, the moving mechanism includes a first fixed plate and a moving plate. The first fixed plate is fixedly mounted on the support rod on the same side as the module. A second drive motor is provided at the lower part of the first fixed plate. One end of a second threaded rod is connected to the output shaft of the second drive motor. The other end of the second threaded rod is rotatably connected to the lower part of the first fixed plate. A connecting block is provided on the moving plate. The connecting block is threadedly connected to the second threaded rod. The welding machine is located at the lower part of the moving plate.

[0006] Furthermore, a second fixing block is provided on the movable plate, and a sliding groove is provided on the second fixing block. A slider is provided at the lower part of the first fixing plate, and the second fixing block slides on the slider through the sliding groove.

[0007] Furthermore, the lifting mechanism includes a first drive motor and a first threaded rod. The first drive motor is mounted on the support rod. One end of the first threaded rod is rotatably connected to the support rod, and the other end is rotatably connected to the base. The first threaded rod is threadedly connected to the moving block, and the moving block slides on the support rod.

[0008] Furthermore, the support rod is L-shaped.

[0009] Furthermore, the connector is configured in a bent shape.

[0010] Furthermore, the connector is bent, and two cylinders are provided on each of the support plates.

[0011] Compared with the prior art, the advantages of the pressing device for processing refrigerator liners provided by this utility model are: By fixing the module and moving the moving block up and down relative to the module, the height of the top position can remain unchanged during pressing. By setting up a clamping mechanism, the cylinder can be used to rotate the flap to press the processed inner liner. After pressing, the moving mechanism drives the welding machine to weld and seal the pressed inner liner. It is easy to use. By setting a moving mechanism, the second threaded rod can be rotated under the drive of the second drive motor, thereby driving the moving plate connected to the connecting block to move back and forth. By setting a sliding groove on the second fixed block, the moving plate can slide on the first fixed plate, ensuring that the clamped inner liner is sealed when the moving plate drives the welding machine to move back and forth, and at the same time ensuring the stability of the movement. This device can make the corners of the refrigerator inner liner tightly pressed together and is easy to use. Attached Figure Description

[0016] like Figure 1-4 As shown, this utility model provides a pressing device for processing the inner liner of a refrigerator, including a base 20 and a support rod 33. A module 32 is fixedly installed on the support rod 33. A movable block 30 is provided below the module 32. The device has a lifting mechanism for driving the movable block 30 to move up and down, a moving mechanism for driving the welding machine 42 to move back and forth, and clamping mechanisms are provided on both sides of the movable block 30.

[0017] The clamping mechanism includes a flap 51, a bent connector 52, a cylinder 53, a support plate 54, and a rotating shaft 55. The support plate 54 is vertically mounted on the base 20 and is located on both sides of the moving block 30. One end of the cylinder 53 is rotatably connected to the outer wall of the support plate 54, and the other end is rotatably connected to one end of the bent connector 52. The other end of the bent connector 52 is fixedly connected to the rotating shaft 55. The rotating shaft 55 is rotatably connected to the support plate 54, and the flap 51 is fixedly connected to the rotating shaft 55.

[0018] Each support plate 54 is provided with two connectors 52, which are located at both ends of the rotating shaft 55. The flap 51 is located on the rotating shaft 55 between the two bent connectors 52. The rotating shaft 55 is rotatably connected to the upper part of the support plate 54. By setting the connectors 52 in a bent shape, it is easy to drive the flap 51 to open and close through the cylinder 53, which is convenient for clamping the inner liner.

[0019] The welding machine 42 includes a fixed tube mounted on a movable plate 41. An electric push rod is installed inside the fixed tube by bolts, and the output end of the electric push rod is connected to the welding head.

[0020] The lifting mechanism is used to move the movable block 30 up and down. The lifting mechanism includes a first drive motor 10 and a first threaded rod 31. The first drive motor 10 is mounted on an L-shaped support rod 33. One end of the first threaded rod 31 is rotatably connected to the L-shaped support rod 33, and the other end is rotatably connected to the base 20. The first threaded rod 31 is threadedly connected to the movable block 30, which rests on the L-shaped support rod 33. The sliding mechanism, with its L-shaped design, facilitates the simultaneous installation of the first drive motor and the first fixed plate for easy operation. The rotation of the first threaded rod causes the moving block to move upward, thus processing the inner liner.

[0021] The moving mechanism drives the welding machine 42 to move and seal the edge of the clamped inner liner. The moving mechanism includes a first fixed plate 40, a moving plate 41, a slider 401, and a second fixed block 411 set on the moving plate 41. A sliding groove is provided on the second fixed block 411. The first fixed plate 40 is fixedly installed on the support rod 33 on the same side as the module 32. A slider 401 and a second drive motor 70 are provided at the lower part of the first fixed plate 40. The second fixed block 411 slides on the slider 401 through the sliding groove. A second threaded rod 71 is rotatably connected to the lower part of the first fixed plate 40. A connecting block is provided on the moving plate 41. The connecting block is threadedly connected to the second threaded rod 71. The welding machine 42 is set at the lower part of the moving plate 41.

[0022] The cylinders used are all existing cylinders with guide rods and are connected to an external air source.

[0023] In use, the raw material sheet of the freezer inner liner is placed on the moving block 30, and then the first drive motor 10 is driven. The first drive motor 10 drives the first threaded rod 31 to rotate, causing the moving block 30 to move upward and extrude and shape the sheet. Then, the telescopic end of the drive cylinder 53 extends, causing the connecting piece 52 to rotate upward, and then the rotating shaft 55 rotates. The rotating shaft 55 rotates, causing the flip plate 51 fixedly connected to the rotating shaft 55 to rotate. Finally, the flip plate 51 rotates until the bottom surface of the flip plate 51 is parallel to the top surface of the freezer inner liner, pressing the excess sheet. Then, the second drive motor 70 drives the second threaded rod 71 to rotate, causing the connecting block to move on the second threaded rod 71. The moving plate 41 connected to the connecting block moves, causing the welding machine 42 at the bottom of the moving plate 41 to weld the gap after pressing. While the moving plate 41 moves, the second fixing block 411 on the moving plate 41 slides with the slider 401 at the bottom of the first fixing plate 40 through the sliding groove to ensure the stability of the moving plate 41 during the movement. After pressing, the telescopic end of cylinder 53 retracts, causing flap 51 to return to its initial state, as shown below. Figure 1 During the reset process, components such as the flip plate 51 will not rub against the top of the refrigerator's inner liner.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
