Description

Technical Field

[0001] This utility model relates to the technical field of aluminum single-panel manufacturing equipment, and in particular to a workpiece support structure for an aluminum single-panel drying equipment. Background Technology

[0002] Aluminum single-layer panels are building decoration materials that are processed by chromating and other treatments, followed by fluorocarbon spraying technology. During the manufacturing process, aluminum single-layer panels need to be sprayed with paint. After the spraying is completed, the sprayed aluminum single-layer panels are removed and taken to a designated location for drying. The conventional method is to place the aluminum single-layer panels in a designated position in a drying oven, and use a blower to introduce air heated by heating coils into the drying oven through air ducts, so that the hot air comes into contact with the aluminum single-layer panels, thereby drying the sprayed surface of the aluminum single-layer panels.

[0003] Current technical problems: Existing drying ovens generally place aluminum panels on a support frame for fixation. Since hot air generally only flows through the outlet fixed on the surface of the air duct to all parts of the oven, the painted surface of the aluminum panel away from the support frame dries first, while the painted surface of the aluminum panel in contact with the support frame is blocked, so this part cannot make good contact with the heating environment, resulting in low drying efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a workpiece support structure for an aluminum single-panel drying equipment, so as to solve the technical problem that the existing drying box fixation method for aluminum single panels cannot make them uniformly contact the hot air, thus affecting the drying efficiency.

[0005] To achieve the above objectives, this utility model provides a workpiece support structure for an aluminum single-panel drying equipment, comprising:

[0006] Rotate at least one turntable located inside the oven cavity;

[0007] At least one rotating shaft whose one end is rotatably connected to the turntable;

[0008] A placement frame fixedly connected to the rotating shaft has an internal placement space for placing workpieces. A slot for inserting workpieces into the placement space is provided on one side of the placement frame. Through slots are provided on the front and rear sides of the placement frame so that the sprayed surface of the workpiece can be exposed to the heating environment.

[0009] A drive assembly for driving the turntable to rotate within the cavity;

[0010] A transmission assembly is used to drive the rotating shaft and the placement frame to rotate relative to the rotating disk while the turntable rotates, so that the workpiece is in uniform contact with the air outlet of the hot air assembly in the inner cavity.

[0011] As a preferred embodiment of this utility model, the driving component includes a motor located at the bottom of the oven, and the output shaft of the motor passes through the bottom of the oven and is connected to the center of the turntable.

[0012] As a preferred embodiment of this utility model, the transmission assembly includes:

[0013] A gear whose one end is connected to the rotating shaft;

[0014] A ring-shaped rack is fixedly installed in the oven, and the ring-shaped rack meshes with a gear.

[0015] As a preferred embodiment of this invention, the size of the placement frame is smaller than the inlet of the oven.

[0016] As a preferred embodiment of the present invention, the placement frame is provided with a first fixing block at one end facing the rotating shaft. The first fixing block has a first positioning hole. The first fixing block is connected to a second fixing block. The second fixing block has a second positioning hole that matches the first positioning hole. A connecting member is provided in the second positioning hole and the first positioning hole.

[0017] As a preferred embodiment of this utility model, the placement frame is rotatably provided with a cover at one end near the slot, and the slot can be opened or closed by rotating the cover.

[0018] As a preferred embodiment of this utility model, one end of the placement frame is provided with a latch to prevent the cap from rotating.

[0019] As a preferred embodiment of this utility model, the hot air assembly includes a ventilation pipe located at the top of the turntable, and the surface of the ventilation pipe has an air vent pointing towards the placement frame.

[0020] As a preferred embodiment of this utility model, the top end of the ventilation pipe passes through the top end of the oven and is rotatably connected to a connector.

[0021] The beneficial effects of this utility model are as follows: This utility model sets a turntable in the drying oven, and a rotating shaft is set on the upper turntable. A placement frame for fixing the workpiece is set on the rotating shaft. Since the placement frame has through slots at both the front and back, the spraying surface on both sides of the workpiece will not be blocked. When the drive component drives the turntable to rotate, due to the action of the transmission component, the placement frame rotates on its own axis while revolving around the revolution, so that the workpiece rotates 360 degrees around the air outlet of the hot air component, ensuring that the spraying surface can be heated evenly and improving the drying efficiency.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] like Figure 1 As shown, a workpiece support structure for an aluminum single-panel drying equipment includes: at least one turntable 5 rotatably disposed in the inner cavity 3 of the drying oven 1; at least one rotating shaft 6 rotatably connected at one end to the turntable 5; a placement frame 7 fixedly connected to the rotating shaft 6, the placement frame 7 having a placement space for placing workpieces inside, a slot 14 for inserting workpieces into the placement space on one side of the placement frame 7, and through slots 13 on the front and rear sides of the placement frame 7 to expose the coated surface of the workpiece to the heating environment; a drive assembly for driving the turntable 5 to rotate in the inner cavity 3; and a transmission assembly for driving the rotating shaft 6 and the placement frame 7 to rotate relative to the turntable 5 while the turntable 5 rotates, so that the workpiece is in uniform contact with the air outlet of the hot air assembly in the inner cavity 3; preferably, four rotating shafts 6 are provided on the turntable 5, and three placement frames 7 are installed at intervals along the length of each rotating shaft 6.

[0032] The above technical solution ensures that the workpiece can be in uniform contact with the hot air. In use, open the oven 1, place the workpiece into the placement space of the placement frame 7 through the through slot 13, close the oven 1, start the hot air assembly, and the hot air assembly blows air to one side of the workpiece through the air outlet. Start the drive assembly to make the turntable 5 rotate. Due to the action of the transmission assembly, the turntable 5 rotates while also driving the rotating shaft 6 and the placement frame 7 to rotate relative to the turntable 5, thereby driving the workpiece in the placement frame 7 to rotate, so that the sprayed surface of the workpiece can alternately contact the air outlet of the hot air assembly, improving the drying efficiency of the workpiece.

[0033] like Figure 2 As shown, in this embodiment, the driving component includes a motor 4 located at the bottom of the oven 1, and the output shaft of the motor 4 passes through the bottom of the oven 1 and is connected to the center of the turntable 5.

[0034] like Figure 2As shown, in this embodiment, the transmission assembly includes: a gear 17 with one end connected to the rotating shaft 6; and an annular rack 18 fixedly disposed in the oven 1, the annular rack 18 meshing with the gear 17.

[0035] The above technical solution enables the placement frame 7 to rotate on its own axis while driving the workpiece to revolve around the sun. When in use, the motor 4 is started so that its output shaft drives the turntable 5 to rotate. The turntable 5 drives the rotating shaft 6 connected to it to rotate synchronously. While the rotating shaft 6 revolves around the sun, the gear 17 located at the bottom of the rotating shaft 6 will continuously mesh with the ring rack 18 in the oven 1, thereby driving the rotating shaft 6 to rotate on its own axis while revolving around the sun, and thus driving the placement frame 7 connected to the rotating shaft 6 to move synchronously.

[0036] like Figure 1 As shown, in this embodiment, the size of the placement frame 7 is smaller than the inlet 2 of the oven 1;

[0037] The above technical solution allows for easy placement or removal of the placement frame 7 from the oven 1, facilitating the replacement and maintenance of the placement frame 7.

[0038] like Figure 4 As shown, in this embodiment, the placement frame 7 is provided with a first fixing block 8 at one end facing the rotating shaft 6. The first fixing block 8 has a first positioning hole 9. The first fixing block 8 is connected to a second fixing block 10. The second fixing block 10 has a second positioning hole 11 that matches the first positioning hole 9. A connecting piece 12 is provided in the second positioning hole 11 and the first positioning hole 9.

[0039] The above technical solution enables the placement frame 7 and the rotating shaft 6 to be detachably connected. When it is necessary to disassemble the placement frame 7, the connecting piece 12 is turned with a tool to disengage the connecting piece 12 from the first positioning hole 9 and the second positioning hole 11, thereby allowing the placement frame 7 to be detached from the rotating shaft 6. In order to improve the connection stability between the placement frame 7 and the rotating shaft 6, grooves can be opened on the opposite sides of the first fixing block 8 and the second fixing block 10. The grooves match the cross-sectional shape of the rotating shaft 6, thereby enabling the first fixing block 8 and the second fixing block 10 to effectively clamp the rotating shaft 6 and prevent the placement frame 7 from loosening.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the placement frame 7 is rotatably provided with a cover 15 at one end near the slot 14, and the slot 14 can be opened or closed by rotating the cover 15; a latch 16 is provided at one end of the placement frame 7 to prevent the cover 15 from rotating.

[0041] The above technical solution can prevent the workpiece from being thrown out of the slot 14 when the placement frame 7 rotates. After the workpiece is inserted into the placement space of the placement frame 7 through the slot 14, the cover 15 is rotated to close the slot 14, and then the latch 16 is operated to abut the cover 15 to prevent the cover 15 from being opened accidentally.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the hot air assembly includes a ventilation pipe 19 located at the upper end of the turntable 5. The surface of the ventilation pipe 19 is provided with an air vent 20 pointing towards the placement frame 7. The top end of the ventilation pipe 19 passes through the top end of the oven 1 and is rotatably connected to a connector 21. Preferably, there are two turntables 5, which are arranged symmetrically about the ventilation pipes 19.

[0043] The above technical solution allows hot air to be introduced into the ventilation pipe 19 and then blown precisely onto the workpiece in the placement frame 7 through the air outlet 20 on the surface of the ventilation pipe 19, thereby drying the workpiece. Since the ventilation pipe 19 rotates together with the turntable 5, a connector 21 is provided to prevent the pipe connected to the ventilation pipe 19 from getting tangled. One end of the connector 21 is fixedly connected to the pipe, and the other end of the connector 21 is rotatably connected to the ventilation pipe 19. This ensures that the ventilation pipe 19 does not force the pipe to rotate when it rotates. The other end of the duct is connected to a blower, which blows the air heated by the heating coil into the ventilation pipe 19 through the duct and the connector 21.

[0044] Working principle: When in use, open the inlet 2 of the oven 1, place the workpiece into the placement space of the placement frame 7 through the through slot 13, rotate the cover 15 to close the slot 14, and then operate the latch 16 to make it abut against the cover 15 to prevent the cover 15 from being opened accidentally. Close the inlet 2 of the oven 1. The blower blows the air heated by the heating coil into the ventilation pipe 19 through the air duct and connector 21. The ventilation pipe 19 blows hot air to the workpiece in the placement frame 7 through the air vents 20 on its surface. Start the motor 4 so that its output shaft drives the turntable 5 to rotate. The turntable 5 drives the rotating shaft 6 connected to it to rotate synchronously. While the rotating shaft 6 revolves, the gear 17 located at the bottom of the rotating shaft 6 will continuously mesh with the ring rack 18 in the oven 1, thereby driving the rotating shaft 6 to rotate on its own axis while revolving, and thus driving the placement frame 7 connected to the rotating shaft 6 to move synchronously. The workpiece in the placement frame 7 rotates synchronously, so that the two sides of the workpiece sprayed surface can alternately contact the air vents 20 on the surface of the ventilation pipe 19, so as to achieve uniform drying of the workpiece and improve the drying efficiency of the workpiece.
