Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:
[0026] Given that current manual operations may not guarantee accurate positioning every time, which affects the stability of blow molding quality and increases the probability of defective products, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a semi-automatic moving and positioning PET bottle blowing machine, including a blowing machine body 1, a moving and positioning mechanism 2 is provided on the right side of the blowing machine body 1, and a conveying mechanism 3 is provided on the front side of the blowing machine body 1.
[0027] The mobile positioning mechanism 2 includes a moving part 21 and a clamping part 22;
[0028] The clamping part 22 is located on the bottom surface of the moving part 21;
[0029] The conveying mechanism 3 includes a conveying section 31 and a limiting section 32;
[0030] The limiting part 32 is located on the top surface of the conveying part 31.
[0031] The moving part 21 includes a U-shaped plate 211, which is fixedly connected to the blow molding machine body 1. A U-shaped fixing plate 212 is provided on the front side of the U-shaped plate 211, which is fixedly connected to the U-shaped plate 211. A motor 213 is provided on the inner side of the U-shaped fixing plate 212, which is fixedly connected to the U-shaped fixing plate 212.
[0032] The output end face of the motor 213 is provided with a threaded rod 214, which is fixedly connected to the motor 213. The threaded rod 214 extends through to the inner side of the U-shaped plate 211 and is threadedly connected to the inner wall of the U-shaped plate 211. The rear end face of the threaded rod 214 is rotatably connected to the inner side of the U-shaped plate 211 through a bearing seat. An L-shaped threaded block 215 is fitted on the surface of the threaded rod 214 and is threadedly connected to the threaded rod 214.
[0033] The clamping part 22 includes a first cylinder 221, which extends through to the bottom of the L-shaped threaded block 215. A U-shaped support frame 222 is provided on the output end face of the first cylinder 221. The U-shaped support frame 222 is fixedly connected to the first cylinder 221. A second cylinder 223 is provided through the inner wall of the U-shaped support frame 222.
[0034] Each cylinder 223 has a clamping plate 224 on its output end face. The distance between the clamping plates 224 is adapted to the distance between the molds of the blow molding machine body 1.
[0035] Furthermore, in this embodiment, the moving positioning mechanism 2 utilizes the motor 213 in the moving part 21. After the motor 213 is started, it drives the connected threaded rod 214 to rotate. The rotation of the threaded rod 214 further drives the L-shaped threaded block 215 to move along the axial direction of the threaded rod 214. The movement of the L-shaped threaded block 215 drives the clamping part 22 to move as a whole from the rear position to above the heat-insulating conveyor belt 313. When the clamping part 22 moves above the heat-insulating conveyor belt 313, the cylinder 221 is activated. The piston rod of the cylinder 221 extends, driving the clamping part 22 to descend as a whole, preparing to clamp the PET bottle. After the clamping part 22 descends to the appropriate position, the cylinder 223 is activated. The piston rod of 23 extends and pushes the clamping plate 224 on the inner side of the U-shaped support frame 222 to clamp the fed PET bottle. After clamping the PET bottle, the reverse operation is performed, that is, the motor 213 rotates in the reverse direction, driving the threaded rod 214 to rotate in the reverse direction. The reverse rotation of the threaded rod 214 causes the L-shaped threaded block 215 to drive the clamping part 22 to move in the reverse direction, conveying the PET bottle to the top of the mold. When the clamping part 22 moves to the top of the mold, the cylinder 221 is started again, causing it to drive the clamping part 22 and the clamped PET bottle to descend into the mold. After the PET bottle is positioned in the mold, the clamping plate 224 releases the clamp on the PET bottle. Then, the motor 213 is started again, and the clamping part 22 is reset by the drive of the threaded rod 214 and the L-shaped threaded block 215, above the heat-insulating conveyor belt 313.
[0036] Furthermore, in this embodiment, the moving positioning mechanism 2 utilizes the motor 213 in the moving part 21. The motor 213 drives the threaded rod 214, which in turn drives the L-shaped threaded block 215. This causes the L-shaped threaded block 215 to move the clamping part 22 above the heat-insulating conveyor belt 313, thereby activating the cylinder 221. The cylinder 221 lowers the clamping part 22, activating the cylinder 223. The cylinder 223 clamps the PET bottle fed into the inner side of the U-shaped support frame 222. After clamping, the operation reverses, causing the threaded rod 214 to transport the bottle above the mold. The cylinder 221 then lowers the clamping part 22 and the clamped PET bottle into the mold, where the mold clamps it. The clamping plate 224 releases its clamping, activating the threaded rod 214 again, causing the clamping part 22 to return to its original position above the heat-insulating conveyor belt 313. By using the blow molding machine body 1 to blow the bottle, precise control of the PET bottle can be achieved. The position and orientation of the bottle in the mold ensure accurate positioning of the preform during the blow molding process, thereby improving the precision and quality of blow molding and reducing the scrap rate. Example 2:
[0037] Please see Figure 1 , Figure 2 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the conveying unit 31 includes a support 311, a control panel 312 is provided on the front side of the support 311, a heat-insulating conveyor belt 313 is provided on the rear side of the control panel 312, the heat-insulating conveyor belt 313 is located on the inner side of the support 311, and spacers 314 are provided on the outer side of the heat-insulating conveyor belt 313. The spacers 314 are fixedly connected to the heat-insulating conveyor belt 313, and the spacing of the inner side of the spacers 314 is adapted to the spacing of the clamping plate 224.
[0038] The limiting part 32 includes a handle 321. Each inner end face of the handle 321 is provided with a threaded rod 322. The threaded rod 322 is fixedly connected to the handle 321. A vertical plate 323 is sleeved on the surface of the threaded rod 322. The vertical plate 323 is threadedly connected to the threaded rod 322. The bottom surface of the vertical plate 323 is fixedly connected to the top surface of the bracket 311. Each inner side of the vertical plate 323 is provided with a limiting plate 324. The limiting plate 324 is rotatably connected to the threaded rod 322.
[0039] Furthermore, in this embodiment, through the conveying mechanism 3, the operator first rotates the handle 321 in the limiting part 32. The rotation of the handle 321 drives the connected threaded rod 322 to rotate. The rotation of the threaded rod 322 further drives the limiting plate 324 to move. The position of the limiting plate 324 is adjusted according to actual needs to set a suitable limiting width. After the limiting plate 324 is adjusted to the position, the PET bottles are placed one by one into the intervals formed by the partition plate 314. After the PET bottles are placed, the heat-insulating conveyor belt 313 is started. The heat-insulating conveyor belt 313 starts to run, driving the PET bottles placed on it to be conveyed.
[0040] Furthermore, in this embodiment, the conveying mechanism 3 utilizes the hand 321 in the limiting part 32 to rotate the threaded rod 322, which in turn drives the limiting plate 324 to adjust and limit the position. After limiting, the PET bottle is placed between the intervals of the spacer plate 314, thereby starting the heat-insulating conveyor belt 313 to transport the bottle, thus ensuring the stability of the conveyor and preventing tipping or tilting.
[0041] In use, the operator first rotates the handwheel 321 in the limiting part 32 via the conveying mechanism 3. The rotation of the handwheel 321 drives the connected threaded rod 322 to rotate, which in turn drives the limiting plate 324 to move. The position of the limiting plate 324 is adjusted according to actual needs to set a suitable limiting width. After the limiting plate 324 is adjusted to the correct position, the heated PET bottles are placed one by one into the spaces formed by the spacer plate 314. After the PET bottles are placed, the heat-insulating conveyor belt 313 is started. The heat-insulating conveyor belt 313 starts to run, driving the bottles to move. PET bottles are conveyed on it, and the control panel 212 controls the rotation speed of the heat-insulating conveyor belt 313 and the moving positioning structure 2. Then, through the moving positioning mechanism 2, the motor 213 in the moving part 21 is used. After the motor 213 is started, it drives the threaded rod 214 connected to it to rotate. The rotation of the threaded rod 214 further drives the L-shaped threaded block 215 to move along the axial direction of the threaded rod 214. The movement of the L-shaped threaded block 215 drives the clamping part 22 to move as a whole, so that it moves from the rear position to above the heat-insulating conveyor belt 313. When the clamping part 22 moves to the heat-insulating conveyor belt 313, the clamping part 22 moves to the top of the heat-insulating conveyor belt 313. After the PET bottle is positioned above the insulated conveyor belt 313, cylinder 221 is activated. When the clamping part 22 moves above the insulated conveyor belt 313, cylinder 221 extends its piston rod, causing the clamping part 22 to descend, preparing to clamp the PET bottle. Once the clamping part 22 reaches the appropriate position, the PET bottle is conveyed between the U-shaped support frames 222. Then, cylinder 223 is activated, extending its piston rod and pushing the clamping plate 224 on the inner side of the U-shaped support frame 222 to clamp the incoming PET bottle. After clamping the PET bottle, the operation reverses, i.e., motor 213 rotates in the opposite direction. The screw rod 214 is rotated in the opposite direction. The reverse rotation of the screw rod 214 causes the L-shaped screw block 215 to move the clamping part 22 in the opposite direction, conveying the PET bottle to the top of the mold. After the clamping part 22 moves to the top of the mold, the cylinder 221 is started again, causing it to move the clamping part 22 and the clamped PET bottle down into the mold. After the PET bottle is positioned in the mold, the clamping plate 224 releases its clamp on the PET bottle. Then, the motor 213 is started again. Driven by the screw rod 214 and the L-shaped screw block 215, the clamping part 22 is reset and placed above the heat-insulating conveyor belt 313.
