[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figures 1-4 The embodiments of this utility model include:
[0022] like Figure 1 The workpiece conveying device for the oven shown is used to convey workpiece 16 in the oven. It includes: a floating frame 1, a rotating shaft mounting seat 6 and a slide seat 2. The rotating shaft mounting seats 6 are arranged at intervals along the length of the floating frame 1 below the floating frame 1. In this embodiment, the oven is short and only two rotating shaft mounting seats 6 are needed.
[0023] like Figure 2 As shown, a rotating shaft 20 extending horizontally along the width direction of the floating frame 1 is rotatably provided in the rotating shaft mounting base 6. A first swing arm 8 extending to one side of the slide rail 13 is provided on the rotating shaft 20. The first swing arm 8 is fixed on the rotating shaft 20 and swings with the rotation of the rotating shaft 20.
[0024] A second swing arm 17 extending downward is provided on the rotating shaft 20. A telescopic cylinder 10 or hydraulic cylinder connected to the second swing arm 17 is provided below the rotating shaft mounting seat 6. The telescopic cylinder 10 or hydraulic cylinder can be telescopically controlled by a PLC and a solenoid valve to realize the swing of the second swing arm 17, drive the rotation of the rotating shaft 20, and thus realize the up and down swing of the first swing arm 8.
[0025] In this embodiment, a third swing arm 18 extending to one side is provided on the rotating shaft 20, and a connecting rod 14 is provided between the third swing arms 18 on the rotating shafts of two adjacent rotating shaft mounting seats 6 to realize the linkage of the two rotating shafts 20 and the stability of the two first swing arms 8.
[0026] A slide rail 13 is horizontally arranged in the floating frame 1, and a roller 9 located in the slide rail 13 is provided on the first swing arm 8. In this embodiment, a groove 12 corresponding to the roller 9 is provided laterally in the slide rail 13. During the up-and-down swinging process of the first swing arm 8, the height of the roller 9 can be changed, thereby realizing the lifting and lowering of the slide rail 13 and the floating frame 1. Figure 3 and Figure 4 As shown, the slide rail 13 is located on both sides of the floating frame 1. The floating frame 1 is driven to rise and fall by the movement of the first swing arm 8 and the roller 9 on both sides. It has high stability, strong load capacity and good adaptability to the self-weight of the workpiece 16.
[0027] like Figure 1As shown, the workpiece 16 is placed on the floating frame 1 with a front-to-back interval. Positioning blocks 15 are set on both sides of the workpiece 16 on the floating frame 1 to position the workpiece, so that the workpiece 16 moves up and down with the floating frame 1.
[0028] The slide 2 is movably positioned below the floating frame 1. The slide 2 is fixed within the oven, ensuring structural stability and preventing it from rising or falling with the floating frame 1. The floating frame 1 has a vertically positioned insert rod 3 pointing towards the slide 2. The slide 2 has a guide member 4 corresponding to the insert rod 3. In this embodiment, the guide member 4 has a C-shaped structure with its opening pointing outwards from the insert rod 3. This guide member can guide the rising and falling of the insert rod 3 and the floating frame 1, preventing the floating frame 1 from shifting along its width.
[0029] To guide the forward and backward movement of the slide 2, a guide rod 19 corresponding to the slide 2 is also required. The slide 2 is mounted on the guide rod 19, allowing it to move horizontally forward and backward along the guide rod 19. Fixed seats 7 are provided at both ends of the guide rod 19, and sprockets 11 are mounted on the fixed seats 7. A chain 5 is installed between the sprockets 11 on the fixed seats 7 at both ends of the guide rod 19 to drive the slide 2 to move forward and backward. A motor 21 is installed on the outside of one of the fixed seats to drive the corresponding sprocket 11 to rotate. The motor 21 drives the sprocket 11 to rotate, which in turn drives the chain 5, thereby causing the slide 2 connected to the chain 5 to move forward and backward a certain distance, and further driving the insertion rod 3 and the floating frame 1 to move forward and backward.
[0030] like Figure 3 As shown, after the workpiece 16 is raised by the floating frame 1, it moves forward under the action of the slide block 2, thus achieving conveying within the oven. Figure 4 As shown, the two ends of the workpiece 16 extend to the outer side of the floating frame 1 in the width direction. A bracket 22 is provided in the oven below the forward movement path of the end of the workpiece 16. The height of the bracket 22 is slightly higher than the height of the floating frame 1 after it descends. This allows the two ends of the workpiece 16 to fall onto the bracket 22 during the descent of the floating frame 1 without affecting the backward movement and reset of the bracket 22. This enables the workpiece 16 to move forward intermittently in the oven. Moreover, the workpiece 16 switches between the bracket 22 and the floating frame 1, avoiding the problem that the part of the bottom of the workpiece 16 that is in contact with the floating frame 1 can never come into contact with the hot air in the oven, resulting in high drying efficiency.
[0031] In summary, the workpiece conveying device for an oven disclosed in this utility model can perform intermittent conveying of workpieces in the oven, with a high degree of automation, thereby improving the drying effect.
[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
