Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, according to Figure 1-7 As shown, the device includes a frame 100, and a feeding device 200 is provided at one end of the frame 100. The feeding device 200 includes a feeding rack assembly 210 and a material suction cup assembly 220. The feeding rack assembly 210 is used to hold materials, and the material suction cup assembly 220 can grab materials from the feeding rack assembly 210 and place them on a secondary positioning platform 230 provided on the frame 100. The edge-oiling device 300 is mounted on the frame 100. The edge-oiling device 300 includes a cantilever assembly 310 and an edge-oiling assembly. The cantilever assembly 310 includes cantilever rods 311 respectively located on both sides of the top of the frame 100. The two cantilever rods 311 are moved by two cantilever drive assemblies. The two cantilever rods 311 can be arranged in parallel to simultaneously pick up the material on the secondary positioning platform 230. After the two cantilever rods 311 pick up the material, the edge-oiling assembly can oil the edge of the material. A baking device 400 is mounted on a frame 100. The baking device 400 includes a baking oven 420 and a circulating transport track 410 passing through the baking oven 420. The transport track 410 is provided with multiple drying rods 413, and each drying rod 413 is provided with multiple material clamps 414. After the cantilever rod 311 sucks up the material, it is transported to the material clamp 414 and clamped. The material is transported into the baking oven 420 for circulating baking under the action of the transport track 410. The material enters from the first end 421 of the baking oven 420. After one cycle of circulating baking, the material clamp 414 is released at the first end 421 of the baking oven 420. The material is stacked on the conveyor belt 430 through the cantilever rod 311. The conveyor belt 430 transports the material to the second end 422 of the baking oven 420 for unloading.

[0029] The specific working steps are as follows: The worker first puts the material that needs to be edge-oiled onto the feeding rack assembly 210. The material suction cup assembly 220 can grab the material from the feeding rack assembly 210 and place it on the secondary positioning platform 230 set on the frame 100 for secondary positioning. The two cantilever rods 311 can alternately pick up the material on the secondary positioning platform 230 under the drive of the two cantilever drive assemblies. After picking up the material, the edge-oiling assembly can oil the edge of the material. Then the cantilever rods 311 move to put the edge-oiled material into the material clamp 414 on the transport track 410. The material is transported into the baking oven 420 for cyclic baking under the action of the transport track 410. It enters from the first end 421 of the baking oven 420. After one cycle of baking, the material clamp 414 is released at the first end 421 of the baking oven 420. The material is stacked on the conveyor belt 430 through the cantilever rods 311. The conveyor belt 430 transports the material to the second end 422 of the baking oven 420 for unloading.

[0030] Specifically, while some existing ovens feature a circulating design, these are all pseudo-circulating designs. They utilize a conveyor belt 430 that transports materials to the second end 422 of the oven, where they fall or are sucked up to the bottom of the baking chamber 420. The conveyor belt 430 then transports the materials to the first end 421 of the baking chamber 420 for unloading. However, not all of the material on the conveyor belt 430 is baked. Only the upper surface of the material is baked, while the lower surface remains unbaked.

[0031] It is understood that during the journey from the first end 421 to the second end 422 of the baking oven 420, the material clamp 414 is in an upward state, and the clamping state allows for baking on both sides of the material. During the journey from the second end 421 to the first end 420 of the baking oven 420, the material clamp 414 is in a downward state, and the clamping state allows for baking on both sides of the material.

[0032] Furthermore, by setting material clamps 414 on the transport track 410, the material can be circulated and baked in the baking oven 420. While reducing the volume of the baking oven 420, the baking time can be increased, thus solving the problem of incomplete drying of the material.

[0033] In another embodiment of this utility model, such as Figure 6 and 7 As shown, the baking apparatus 400 also includes a first opening component 440 and a second opening component 450 disposed on the frame 100; both the first opening component 440 and the second opening component 450 are disposed on the frame 100 and the first opening component 440 is disposed above the second opening component 450, the first opening component 440 and the second opening component 450 are located at the same end, and the first opening component 440 and the second opening component 450 can open and close multiple material clamps 414 on the same drying rod 413.

[0034] Understandably, when a drying rod 413 is transported from the second end 422 of the baking oven 420 to the first end 421, it is transported to the second opening component 450. The second opening component 450 opens a row of material clamps 414 on the drying rod 413, and the material is stacked on the conveyor belt 430 through the cantilever rod 311. The drying rod 413 continues to move, and the first opening component 440 can open a row of material clamps 414 on the drying rod 413, holding the material clamps 414 sucked by the cantilever rod 311 on a row of material clamps 414. This cycle is repeated to continuously dry the oiled material.

[0035] The first opening assembly 440 includes a first opening rod 441 and driving members 442 at both ends of the first opening rod 441. Each driving member 442 is equipped with a first opening cylinder 443. The first opening cylinder 443 drives the driving member 442 to make the first opening rod 441 approach and move away from the multiple material clamps 414 on the corresponding drying rod 413, thereby opening and closing the multiple material clamps 414. Specifically, when the material clamps 414 are transported to the bend, the row of material clamps 414 is horizontally placed. The first opening cylinder 443 drives the driving member 442 to make the first opening rod 441 approach and open the horizontal material clamps 414 in an arc-shaped motion. The cantilever rod 311 can then horizontally place the material at the clamping opening. When the first opening rod 441 moves away from the material clamps 414, the material clamps 414 close their clamping openings, thus holding the material. Furthermore, the first opening assembly can be coordinated with the movement of the cantilever rod 311 to open the material clamps 414, which is simple and quick.

[0036] The second opening assembly 450 includes a second opening rod 451; each end of the second opening rod 451 is connected to a second opening cylinder 452. The second opening cylinder 452 drives the second opening rod 451 to approach and move away from the corresponding drying rod 413 by telescopically driving it, thereby opening and closing the multiple material clamps 414. At this time, the material clamps 414 are transported before the turn, and the row of material clamps 414 is inverted and placed vertically. The second opening cylinder 452 drives the second opening rod 451 to approach and open the material clamps 414 horizontally by telescopically driving it, and the material falls onto the bottom conveyor belt 430. The second opening rod 451 then moves horizontally away from the material clamps 414, and the material clamps 414 return to their original position.

[0037] Furthermore, as an alternative, an extension rod can be provided between the two second opening cylinders 452 and the second opening rod 451, and an opening block for opening the material clamp 414 can be provided on the second opening rod 451, with the number and position of the multiple opening blocks corresponding to the number and position of the material clamp 414.

[0038] In another embodiment of this utility model, such as Figure 5As shown, the cantilever 311 includes a vertical plate 3111 and a horizontal plate 3112. The cantilever drive assembly includes a cantilever lateral drive assembly 3121 and a cantilever longitudinal drive assembly 3122. The horizontal plate 3112 is movably connected to the vertical plate 3111 through the cantilever longitudinal drive assembly 3122. The top of the frame 100 is provided with a top sealing plate. The two sides of the top sealing plate are respectively provided with cantilever lateral drive assemblies 3121. The two cantilever lateral drive assemblies 3121 are respectively connected to the corresponding vertical plates 3111. The cantilever lateral drive assembly 3121 can drive the vertical plate 3111 to move laterally, and the cantilever longitudinal drive assembly 3122 can drive the horizontal plate 3112 to move longitudinally.

[0039] Specifically, the horizontal plate 3112 can move back and forth and up and down by the cooperation of the cantilever longitudinal drive component 3122 and the cantilever lateral drive component 3121. The horizontal plate 3112 is equipped with a first suction cup component 313, which is used to pick up materials. The materials can be picked up and oiled, and then the materials can continue to move and be placed on the transport track 410.

[0040] Furthermore, the first suction cup assembly 313 and the second suction cup assembly 223 have similar structures, including multiple arranged suction heads and air tubes. The air tubes can be connected to external vacuum pumps or vacuum generators to achieve material suction. The first suction cup assembly 313 and the second suction cup assembly 223 can simultaneously suction two pieces of material.

[0041] Furthermore, when the first suction cup assembly 313 picks up two pieces of material, a material support assembly 120 is also set near the baking oven 420. The first suction cup assembly 313 picks up two pieces of material, and as long as the side closest to the material clamp 414 can be clamped, the material away from the material clamp 414 needs to be placed on the material support assembly 120. After one side is clamped, the end of the first suction cup assembly 313 near the material clamp 414 will then pick up the material on the material support assembly 120 for clamping the next row of material clamps 414.

[0042] Furthermore, the cantilever longitudinal drive assembly 3122 includes a slide rail, a motor, and a belt. The belt passes through and connects to the vertical plate 3111. The motor drives the belt to move and move the vertical plate 3111, which slides on the slide rail. The cantilever longitudinal drive assembly 3122 consists of a motor and a lead screw. The horizontal plate 3112 is connected to a slider on the lead screw and moves up and down under the drive of the motor.

[0043] In another embodiment of this utility model, such as Figure 4 and 5As shown, the edge-oiling assembly includes multiple edge-oiling units 321 and an edge-oiling drive assembly 322 that drives the multiple edge-oiling units 321. The edge-oiling units 321 can oil the edges of the material after it is sucked up by the two cantilever rods 311. Furthermore, the edge-oiling drive assembly 322 includes a forward, backward, left, and right moving device, which can be driven by a motor or a cylinder, in conjunction with a guide rail, as long as forward, backward, left, and right movement is possible. The edge-oiling units 321 include a geared oiler and an oil box, etc. For the specific structure, please refer to the patent with publication number CN109957627B. Those skilled in the art will clearly understand its structure from the name.

[0044] In another embodiment of this utility model, according to Figure 2 and 3 As shown, the loading rack assembly 210 includes two loading trays 211 and a switching device 212. The switching device 212 can rotate and move the two loading trays 211, allowing them to alternately approach the material-picking suction cup assembly 220. By setting the switching device 212, alternating material feeding can be achieved, resulting in higher processing efficiency. When one loading tray 211 is feeding material near the material-picking suction cup assembly 220, the other loading tray 211 is near the external opening, allowing workers to fill the loading tray 211. After switching via the switching device, this process is repeated sequentially. The switching device can be understood to include symmetrically arranged motors and connecting rods. Each connecting rod connects to both ends of the two loading trays 211. The motor drives the connecting rods to rotate, thereby moving the positions of the two loading trays 211. Furthermore, gears and belts can be added to each end. One end of each belt is connected to the motor gear, and the other end is connected to one end of each of the different loading trays 211, making rotation easier.

[0045] In another embodiment of this utility model, according to Figure 2 and 3 As shown, the material-grabbing suction cup assembly 220 includes a material-grabbing suction cup arm 221 and a material-grabbing drive device 222 for driving the material-grabbing suction cup arm 221 to move. The material-grabbing drive device 222 can drive the material-grabbing suction cup arm 221 to move back and forth and up and down. The material-grabbing suction cup arm 221 is provided with a second suction cup assembly 223, which can pick up materials. Furthermore, the material-grabbing drive device 222 can be a combination of a motor, belt and slide rail, or it can be driven by two cylinders to achieve movement. As a preferred choice, the combination of a motor and belt and slide rail results in smoother movement and faster speed.

[0046] In another embodiment of this utility model, according to Figure 4As shown, the secondary positioning platform 230 is equipped with multiple positioning bars 231. The positioning bars 231 are used to limit the material. During secondary positioning, the material is placed according to our requirements, which facilitates subsequent material handling and edge painting. Otherwise, there may be problems such as excessive gap between the leather and the edge painting device 300 or direct contact between the edge of the leather and the edge painting device 300, which will lead to uneven ink after the leather is edge painted.

[0047] In another embodiment of this utility model, according to Figure 6 and 7 As shown, the transport track 410 includes a rotating roller 411 and chains 412 disposed at both ends of the rotating roller 411. A transport drive device can drive the rotating roller 411 to rotate, thereby driving the two chains 412 to move. Multiple drying rods 413 are disposed between the two chains 412. The transport drive device can be a conventional motor, which can directly drive the rotating roller 411 or drive the rotating roller 411 to rotate via a belt, thereby driving the chains 412 at both ends to move.

[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
