[0028] As shown in the accompanying drawings, Figure 1, 2 As shown in Figure 3, the loading and unloading assembly 1 includes a loading and unloading bracket 11, a longitudinal moving chain unit 12, a transverse moving pneumatic unit 13, several material trays 14, and a robotic arm 15.
[0029] The longitudinal moving chain unit 12 is fixed on the loading / unloading bracket 11 and includes a motor 120, a chain 121, a raw material pallet 122, and a finished product pallet 123. The raw material pallet 122 and the finished product pallet 123 are located on both sides of the chain 121 and are slidably connected to the loading / unloading bracket 11. They can reciprocate under the drive of the chain 121. When the raw material pallet moves upward, the finished product pallet moves downward by the same distance. The material tray 14 is placed on the raw material pallet 122 and the finished product pallet 123 to carry raw materials or finished products. The material trays 14 can be stacked on the raw material pallet 122 and the finished product pallet 123.
[0030] The lateral movement pneumatic unit 13 is used to drive the uppermost material tray 14 to move laterally from the raw material pallet 122 to the finished product pallet 123. It includes a whole tray lateral movement rodless cylinder unit 131 and a whole tray bottom support cylinder unit 132. The whole tray bottom support cylinder unit 132 is used to lift the uppermost material tray 14 and move it under the drive of the whole tray lateral movement rodless cylinder unit 131.
[0031] The robotic arm 15 is mounted on the equipment housing 4 and is used to transfer the raw materials in the uppermost tray 14 to the rotary platform assembly 2.
[0032] As attached Figure 1 , 4 As shown in Figure 5, the rotating platform assembly 2 includes a drive unit 21, a turntable 23, and raw material limiting tubes 22. The turntable 23 is rotatably mounted on the equipment housing 4 and rotates under the drive unit 21. Multiple raw material limiting tubes 22 are arranged in a circumferential array at the edge of the turntable 23. The robotic arm 15 transfers the raw material into the raw material limiting tubes 22.
[0033] As attached Figure 6 , 7 As shown in Figures 8 and 9, the activation component 3 includes a flame gun 31, an arc-shaped guide rail 32, a horizontal rail 33, a vertical rail 34, a slide groove 35, a sliding track groove plate 36, a turntable bearing 37, a sliding bracket 38, a tension spring 39, and a compression spring 310.
[0034] The turntable bearing 37 is rotatably mounted on the outside of the turntable 23, specifically at the center of two adjacent raw material limiting tubes 22. The edge of the turntable bearing 37 extends out of the turntable 23, and the end of the horizontal rail 33 is at the same height as the turntable bearing 37.
[0035] Horizontal linear rail 33 is arranged on sliding bracket 38, bottom of sliding bracket 38 is slidably connected with arc-shaped guide rail 32, one side of sliding bracket 38 is connected to equipment box 4 through tension spring 39.
[0036] When rotating disc 23 rotates and rotating disc bearing 3 below rotating disc contacts with end of horizontal linear rail 33, a forward (rotating direction of rotating disc 23) force is applied to horizontal linear rail 33, thereby driving sliding bracket 38 to slide on arc-shaped guide rail 32, arc-shaped guide rail 32 is concentric with rotating disc 23, so that distance between sliding bracket 38 and raw material limiting pipe 22 on rotating disc 23 is fixed during rotation. When rotating disc 23 continues to rotate, and rotating disc bearing 3 below rotating disc is out of contact with horizontal linear rail 33, and sliding bracket 38 returns to the initial sliding position under the action of tension spring 39, the next bearing below rotating disc applies a pushing force to the linear rail, so that rotation synchronization of each product butt joint is realized.
[0037] Horizontal linear rail 33 includes fixed part 331 and sliding part 332, fixed part 331 is fixedly arranged on sliding bracket 38, and sliding part 332 can slide in the horizontal direction relative to fixed part 331, one side of sliding part 332 is close to rotating disc 23, and one end of lower part is provided with sliding block 333, sliding block 333 is matched with sliding groove 35, rectangular groove matched with sliding block 333 is arranged in sliding groove 35, and sliding groove 35 is arranged in an inclined manner, in one embodiment, sliding groove 35 can be arranged along the tangent direction of arc-shaped guide rail 32, or can be arranged along the intersecting line direction.
[0038] During the contact between horizontal linear rail 33 and rotating disc bearing 37, sliding part 332 of horizontal linear rail 33 is driven by rotating disc bearing 37 to drive fixed part 331 and sliding bracket 38 to move along arc-shaped guide rail 32, and due to the limiting of sliding groove 35 to sliding block 333, sliding part 332 of horizontal linear rail 33 is outwardly drawn away from the center of rotating disc 23.
[0039] Sliding track groove plate 36 is arranged on sliding part 332 of horizontal linear rail 33 and is arranged in a vertical manner and provided with irregular slide.
[0040] Vertical linear rail 34 includes vertical linear rail fixed part 341 and vertical linear rail sliding part 342, vertical linear rail fixed part 341 is fixed vertically on sliding bracket 38, vertical linear rail sliding part 342 can slide in the vertical direction relative to vertical linear rail fixed part 341, vertical sliding block 343 is arranged at the bottom of vertical linear rail sliding part 342 and matched with the slide of sliding track groove plate 36. Vertical linear rail sliding part 342 is connected to sliding bracket 38 through compression spring 310 at the middle upper part, and flame gun 31 is arranged at the top of vertical linear rail sliding part 342.
[0041] When the rotating disc rotates, the sliding part 332 of the horizontal linear rail moves outward, which drives the sliding track groove plate 36 on the sliding part 332 to move outward, and drives the vertical linear rail sliding part 342 to move up and down through the cooperation of the sliding groove and the vertical sliding block 343.
[0042] The flame spray gun 31 is L-shaped, one end of which is fixed at the top of the vertical linear rail sliding part 342, and the flame outlet is downward and located at the upper part of the raw material limiting pipe 22.
[0043] More specifically, the sliding groove 361 on the sliding track groove plate 36 is an inverted right-angle trapezoid, and the side far from the rotating disc 23 is a right-angle side. The initial position is the highest position of the right-angle side. When the initial position, the compression spring 310 is under pressure, and the sliding part 332 of the horizontal linear rail is not in contact with the rotating disc bearing 3, the shell thread area is not below the flame spray gun 31, and the sliding support 38 is at the initial position of the arc-shaped guide rail 32.
[0044] Under the action of the compression spring 310, the vertical sliding block 343 moves under the limitation of the sliding groove 361, thereby driving the vertical linear rail sliding part 342 and the flame spray gun 31 to move downward, so that the action range of the flame spray gun 31 moves downward. When the horizontal linear rail sliding part 332 starts to contact the rotating disc bearing 3 at the bottom horizontal side of the sliding groove 361, the vertical sliding block 343 enters the bottom horizontal side area of the sliding groove 361, and the shell thread area enters the flame action range. After that, the horizontal linear rail continues to move outward, the flame spray gun 31 remains at the existing height, and at the same time, the sliding support 38 drives the flame spray gun 31 to slide along the arc-shaped guide rail 32, realizing the same direction movement of the flame spray gun 31 and the raw material on the rotating disc, and performing the activation operation in the movement process.
[0045] When the horizontal linear rail sliding part 332 continues to move outward, the vertical sliding block 343 moves to the position of the inclined side of the sliding groove 361, the flame spray gun 31 will start to move upward, away from the shell thread area, and gradually move to the highest point. A tab 3611 is arranged at the highest position of the inclined side of the sliding groove 361, which will be moved by the vertical sliding block 343 when the vertical sliding block 343 moves on the inclined surface. When the horizontal linear rail is separated from the thrust of the rotating disc bearing, the vertical sliding block 343 moves to the inclined side of the sliding groove 361, and the tab 3611 will return to the horizontal position due to the torsional spring installed inside. Through the size setting of the tab 3611, it can only allow the vertical sliding block 343 to be lifted from bottom to top. When the vertical sliding block 343 is under the action of the compression spring 310, it moves downward in the inclined side area of the sliding groove 361.
[0046] When the horizontal linear rail is not under the thrust of the rotating disc bearing and the tension spring 39 drives the sliding support to recover, the horizontal linear rail will also slide inward under the drive of the sliding groove, and the vertical sliding block 343 will not move downward along the inclined surface due to the tab, but will move horizontally to the right side of the lower turning position, that is, the initial position, which completes a processing cycle.
[0047] The equipment box 4 comprises a bottom box part 41 and a working part 42, wherein the bottom box part 41 is in a closed box shape, is provided with an openable cabinet door, the working part 42 is arranged on the upper part of the bottom box part 41, is provided with openings on one side and the opposite side of the feeding and discharging assembly 1, and is provided with a smoke pipe 421 on the top and an openable observation window 422 on the side wall.
