[0013] A production device and method for polymer plastic bottles for pesticide storage, comprising the following steps:

[0014] S1: When using the device, first move the device to a designated position, then place the plastic preform between the two sliding molds, and then start the motor to move the two sliding molds closer to each other, thereby forming a complete mold;

[0015] S2: The fixed sleeve gear continues to rotate, driving the rotating shaft to rotate through the belt, thereby causing the compression plate to reciprocate up and down, so as to continuously guide air into the sliding mold through the air guide compression pipe for heat dissipation;

[0016] S3: After the plastic bottle is formed, the motor is controlled to flip it, and the lifting plate moves upward to demould the plastic bottle from the fixed mold, and air is discharged from the air holes to push the plastic bottle upward to separate it from the lifting plate.

[0017] The present invention has the following beneficial effects:

[0018] (1) In the process of the two moving plates moving away from each other, the moving plate will drive the pressure rod 2 to move together. The movement of the pressure rod 2 will compress the air in the fixed tube and push the air into the air guide tube. The air guide tube will pass the air into the fixed block. The air passed into the fixed block will pass through the workbench and finally enter the interior of the fixed mold. The air entering the fixed mold will push the lifting rod upward. The lifting rod will move upward with the lifting plate to demold the plastic bottle from the fixed mold. When the lifting rod moves to the final position, it will pull the lifting sleeve rod to rise again. The lifting sleeve rod will compress the spring 3 during the movement. When the spring Third, after moving to a certain position, excess air will be discharged from the air outlet, and the lifting sleeve will no longer be pushed upward. The air discharged from the air outlet will push the plastic bottle upward to separate it from the lifting plate. When the moving plates approach each other next time, the fixed tube will suck air into the fixed tube through the air inlet one-way valve 2. This design can lift the plastic bottle upward through the lifting plate to facilitate discharging, and the contact area between the lifting plate and the bottom of the plastic bottle is large, which will not cause damage to the bottom of the plastic bottle. In the process of lifting, the bottom of the plastic bottle and the top of the lifting plate will be separated by the blown air to prevent the two from sticking.

[0019] (2) In the present invention, when the two moving plates are approaching each other, the moving plates will move together with the pressure rods. When the pressure rods come into contact with the fixed ring, as the moving plate continues to move, the pressure rods will be squeezed and move toward the inside of the moving plate. During the movement, the pressure rods will squeeze the air inside the moving plate and push the air into the air guide hose. The air guide hose will pass the air into the inside of the fixed block. The air passed into the fixed block will give a thrust to the limit ring, but at this time the thrust is not enough to stretch the spring. When the two sliding molds come into contact with each other, the air pressure at this time is large enough. The force will push the sliding sleeve teeth in the direction away from the fixed sleeve teeth, thereby causing the sliding sleeve teeth to disengage from the fixed sleeve teeth. This design allows the sliding sleeve teeth to disengage from the fixed sleeve teeth after the two sliding molds are merged, so that the device can continue to rotate the rotating shaft without affecting the merging of the sliding molds, thereby providing power for subsequent components.

[0020] (3) In the above process of the present invention, the fixed sleeve gear continues to rotate and drives the rotating shaft to rotate through the belt, and the rotating shaft drives the rotating disk to rotate. When the rotating disk rotates, it causes the compression plate to reciprocate up and down through the rotating rod. When the compression plate rises, it compresses the air in the fixed box and passes the air into the air guide compression tube. When the compression plate descends, it sucks the external air into the fixed box through the air intake check valve. The air passed into the air guide compression tube will pass through the gradually reduced diameter of the air guide compression tube and finally enter the sliding mold. The air entering through the large port and exiting through the small port will increase the air pressure and flow rate and reduce the temperature. After the air enters the sliding mold and passes through several heat conducting plates, it will be discharged from the back of the sliding mold, thereby cooling the sliding mold. This design allows high-flow-rate and low-temperature air to enter the sliding mold through the air guide compression tube and quickly flow out, which can bring out the temperature in the sliding mold, thereby cooling the sliding mold, so that the plastic bottle preform can be quickly solidified and cooled after contacting the inner wall of the sliding mold.

[0021] (4) After the plastic bottle is formed, the motor is controlled to reverse. At this time, the fixed sleeve tooth drives the friction ring to rotate. While the friction ring rotates, it drives the sealing plate to slide and compresses the spring 2 through the traction rope. When the sealing plate moves to the final position and cannot move any further, the fixed sleeve tooth overcomes the friction between it and the friction ring and rotates alone. However, due to the friction force, the friction ring always applies a pulling force to the sealing plate so that it will not reset. In the above process, after the sealing plate moves to a certain position, the through hole at the bottom of the fixed block is exposed. At this time, the air introduced into the fixed block by the air guide hose is discharged from the exposed through hole, thereby reducing the air pressure in the fixed block. The pressure rod 1 is reset under the action of the reset spring. The limit ring drives the sliding sleeve tooth to mesh with the fixed sleeve tooth again under the action of the spring 1, thereby driving the two sliding molds away from each other through the fixed sleeve tooth, and the formed plastic bottle will remain in the fixed mold. This design can control the sliding mold to separate to both sides for automatic demolding, eliminating the time and labor cost of manual demolding, thereby improving work efficiency.

At this time, the plastic bottle embryo can be blow molded.

[0041] The inner wall of the sliding mold 107 is slidably connected to the limiting frame 108, the bottom of the limiting frame 108 is fixedly connected to the top of the workbench 101, the top of the workbench 101 is fixedly connected to the fixed mold 109, the inner wall of the moving plate 106 is slidably connected to the pressure rod 110, the pressure rod 110 is fixedly connected to the side away from the fixed sleeve tooth 103 with a return spring 1101, the return spring 1101 is fixedly connected to the inner wall of the moving plate 106 on the side away from the pressure rod 110, and the moving plate 106 is fixedly connected to the inner wall of the moving plate 106 on the side away from the fixed sleeve tooth 103. An air guide hose 111 is fixedly connected to one side of the sleeve tooth 103. When the two movable plates 106 approach each other, the movable plate 106 will move with the pressure rod 110. When the pressure rod 110 contacts the fixed ring 116, as the movable plate 106 continues to move, the pressure rod 110 will be squeezed and move toward the inside of the movable plate 106. During the movement, the pressure rod 110 will squeeze the air inside the movable plate 106 and push the air into the air guide hose 111.

[0042] The air guide hose 111 is fixedly connected to a fixed block 112 at one end away from the movable plate 106, the top of the fixed block 112 is fixedly connected to the bottom of the workbench 101, the inner wall of the fixed block 112 is slidably connected to a limiting ring 113, the inner wall of the limiting ring 113 is rotatably connected to the outer surface of the sliding sleeve tooth 104, the inner wall of the limiting ring 113 is slidably connected to a limiting rod 114, the outer surface of the limiting rod 114 is sleeved with a spring 115, the left and right sides of the spring 115 are respectively fixedly connected to the right side of the limiting ring 113 close to the left and the left side of the limiting ring 113 close to the right, the left and right sides of the limiting rod 114 are fixedly connected to a fixing ring 116, the top of the fixing ring 116 is fixedly connected to the bottom of the workbench 101, and the outer surface of the fixed sleeve tooth 103 contacts with a friction ring 1 17.

The two sliding sleeve teeth 104 will drive the two threaded sleeves 105 to rotate. The rotation of the two threaded sleeves 105 will drive the two sliding molds 107 to approach each other through the two moving plates 106, thereby forming a complete mold. At this time, the plastic bottle embryo can be blow-molded. In the process of the two moving plates 106 approaching each other, the moving plate 106 will move with the pressure rod 110. When the pressure rod 110 contacts the fixed ring 116, as the moving plate 106 continues to move, the pressure rod 110 will be squeezed and moved toward the moving plate 106. The movable plate 106 moves internally, and the pressure rod 110 will squeeze the air inside the movable plate 106 during the movement, and push the air into the air hose 111, and the air hose 111 will pass the air into the fixed block 112. The air passed into the fixed block 112 will give a thrust to the limit ring 113, but at this time the thrust is not enough to stretch the spring 115. When the two sliding molds 107 contact each other, the air pressure at this time is large enough, and the force will push the sliding sleeve teeth 104 in the direction away from the fixed sleeve teeth 103, thereby disengaging the sliding sleeve teeth 104 from the fixed sleeve teeth 103. This design allows the sliding sleeve teeth 104 to disengage from the fixed sleeve teeth 103 after the two sliding molds 107 are merged, so that the device can continue to rotate the rotating shaft 1021 without affecting the merging of the sliding molds 107, thereby providing power for subsequent components;

[0052] During the above process, the fixed sleeve gear 103 continues to rotate, which drives the rotating shaft 202 to rotate through the belt 201, and the rotating shaft 202 drives the rotating disk 203 to rotate. When the rotating disk 203 rotates, it causes the compression plate 205 to reciprocate up and down through the rotating rod 204. When the compression plate 205 rises, it compresses the air in the fixed box 206 and passes the air into the air-guiding compression pipe 209. When the compression plate 205 descends, it sucks the external air into the fixed box 206 through the air intake check valve 207. The air passed into the air-guiding compression pipe 209 passes through the gradually shrinking tube of the air-guiding compression pipe 209. The air enters the sliding mold 107 through the large opening and exits through the small opening. As the air pressure increases, the flow rate increases and the temperature decreases. After the air enters the sliding mold 107 and passes through a plurality of heat conducting plates 210, it is discharged from the back of the sliding mold 107, thereby cooling the sliding mold 107. This design allows high-flow-rate and low-temperature air to enter the sliding mold 107 through the air-conducting compression tube 209 and quickly flow out, thereby bringing out the temperature in the sliding mold 107, thereby cooling the sliding mold 107, and allowing the plastic bottle embryo to quickly solidify and cool after contacting the inner wall of the sliding mold 107.

[0053] After the plastic bottle is formed, the motor 102 is controlled to reverse, and the fixed sleeve gear 103 drives the friction ring 117 to rotate. While the friction ring 117 rotates, it drives the sealing plate 119 to slide and compress the spring 120 through the traction rope 118. When the sealing plate 119 moves to the final position and cannot move any further, the fixed sleeve gear 103 overcomes the friction between the fixed sleeve gear 103 and the friction ring 117 and rotates alone, and the friction ring 117 always applies a pulling force to the sealing plate 119 due to the friction force so that it will not reset. In the above process, after the sealing plate 119 moves to a certain position, the through hole at the bottom of the fixed block 112 is exposed. At this time, the air guide hose 111 is passed into the fixed block 112. The air will be discharged from the exposed through hole, thereby reducing the air pressure in the fixed block 112, and the pressure rod 110 will be reset under the action of the reset spring 1101, and the limit ring 113 will drive the sliding sleeve teeth 104 to re-engage with the fixed sleeve teeth 103 under the action of the spring 115, and then drive the two sliding molds 107 to move away from each other through the fixed sleeve teeth 103, and the molded plastic bottle will remain in the fixed mold 109. This design can control the sliding mold 107 to separate to both sides for automatic demoulding, eliminating the time and labor cost of manual demoulding, thereby improving work efficiency; in the process of the two moving plates 106 moving away from each other, the moving plate 106 will drive the pressure rod 2 301 The movement of the pressure rod 2 301 will compress the air in the fixed tube 302 and push the air into the air duct 304, and the air duct 304 will pass the air into the fixed block 112. The air passed into the fixed block 112 will pass through the workbench 101 and finally enter the interior of the fixed mold 109. The air entering the fixed mold 109 will push the lifting rod 305 upward, and the lifting rod 305 will move upward with the lifting plate 308 to demould the plastic bottle from the fixed mold 109. When the lifting rod 305 moves to the final position, it will pull the lifting sleeve rod 306 to rise again. The lifting sleeve rod 306 will compress the spring three 307 during the movement. When the spring three 307 moves to After reaching a certain position, the excess air will be discharged from the air outlet 309, and the lifting sleeve 306 will no longer be pushed upward. The air discharged from the air outlet 309 will push the plastic bottle upward to separate it from the lifting plate 308. When the moving plates 106 approach each other next time, the fixed tube 302 will suck air into the fixed tube 302 through the air inlet check valve 303. This design can lift the plastic bottle upward through the lifting plate 308 to facilitate discharge, and the contact area between the lifting plate 308 and the bottom of the plastic bottle is large, so it will not cause damage to the bottom of the plastic bottle. In the lifting process, the bottom of the plastic bottle and the top of the lifting plate 308 will be separated by the blown air to prevent the two from sticking.
