[0002] A preform production unit is a device specifically designed to manufacture preforms. The preform is the initial form of a bottle before it's formed, typically in a tubular or nearly tubular shape. It serves as a key intermediate product for subsequent bottle production through processes like blow molding. The preform production unit processes plastic raw materials (such as PET and PP) through a complex series of processes, including heating and injection molding, to efficiently and accurately produce preforms that meet specific specifications and quality requirements.
[0003] In the prior art, the conventional steps require that the preforms be removed from the mold by a conveying device or a robot arm. However, in the prior art, the distance between the preforms during demolding is different from the distance between them after unloading. When the robot arm clamps the preforms, the accuracy of clamping and unloading is low due to the different distances between the preforms. Therefore, a material unloading adjustment structure of the preform production device is proposed to solve the above problem. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Reference Figures 1 to 2The present invention provides an embodiment of a blanking adjustment structure for a preform production device, comprising a mounting frame 5, made of aluminum alloy and shaped like a frame, possessing sufficient strength and rigidity to support and secure other components. A slide plate 9, also made of aluminum alloy sheet and having a rectangular shape, is slidably connected to the mounting frame 5. The slide plate 9 is internally provided with a plurality of inclined guide grooves 10. The inclined guide grooves 10 function to convert the horizontal linear motion of the slide plate 9 into horizontal sliding motion of the other structures through contact and relative motion with subsequent structures, thereby achieving distance adjustment. A guide tube 11 is fixedly connected to the mounting frame 5 internally. The surface of the guide tube 11 is chrome-plated to improve its wear resistance and surface smoothness, reduce friction with subsequent structures, and provide a guide for its sliding. A plurality of sliding clamping blocks 12 are slidably connected to the exterior of the guide tube 11. The sliding clamping blocks 12 have holes internally provided to mate with the guide tube 11, enabling the sliding clamping blocks 12 to slide axially along the guide tube 11. The top of the sliding clamping block 12 is fixedly connected to a plurality of protruding knobs 13. The protruding knobs 13 are cylindrical and their dimensions must match the dimensions of the inclined guide groove 10 so that they can slide smoothly within the inclined guide groove 10. The top of the mounting frame 5 is fixedly connected to a fixed block 6. The fixed block 6 is generally made of steel and is block-shaped with a large surface area and a certain thickness to provide sufficient strength and stability to maintain the stable installation of the subsequent drive structure. The left side of the fixed block 6 is fixedly connected to an electric push rod 7, which provides a power source for the adjustment component. The top of the slide 9 is fixedly connected to a connecting column 8. The position of the connecting column 8 must be accurately installed in the center of the slide 9 to ensure that the slide 9 can be evenly stressed when it is pushed and slide smoothly to avoid tilting or jamming. A control component for controlling the movement of the mounting frame 5 is provided on the top of the mounting frame 5, and a clamping component for clamping the bottle blank is provided inside the sliding clamping block 12. The right side of the connecting column 8 is fixedly connected to the left side of the driving end of the electric push rod 7. When the electric push rod 7 is working, the thrust of its driving end is transmitted to the slide 9 through the connecting column 8, so that the slide 9 slides inside the mounting frame 5. The outside of multiple convex buttons 13 contacts the inside of the inclined guide groove 10. The convex buttons 13 must be able to be accurately embedded in the inclined guide groove 10, and when the slide 9 slides, it can drive the sliding clamping block 12 to slide along the guide tube 11 and adjust its position under the guidance of the inclined guide groove 10.
[0031] Reference Figure 1The control assembly includes multiple support legs 1, each made of steel and cylindrical in shape. The combined support legs 1 have a large cross-section, providing sufficient support stability. Two electric slide rails 2 are fixedly connected to the tops of the multiple support legs 1. These slide rails 2 provide precise horizontal movement for the sliding structure above, enabling quick and accurate switching between different positions to meet the varying demands of the blanking adjustment structure during preform production. Sliding blocks 3 are slidably connected to the exteriors of the two electric slide rails 2. A hydraulic rod 4 is fixedly connected to the bottoms of these blocks. The drive end of the hydraulic rod 4 is fixedly connected to the top of the mounting frame 5. The hydraulic rod 4 is a key component in the control assembly that provides vertical power. When the blanking adjustment structure needs to be lowered to contact the preform for clamping and blanking, the piston rod of the hydraulic rod 4 extends, pushing the mounting frame 5 and the components below it downward. When blanking is complete, the piston rod retracts, raising the mounting frame 5 to its initial position.
[0032] Reference Figures 3 and 4 The clamping assembly includes multiple pneumatic push rods 14, and the outsides of the multiple pneumatic push rods 14 are fixedly connected to the inside of the sliding clamping block 12. The function of the pneumatic push rods 14 is to provide a power source. Through the entry and discharge of compressed air, the piston rod is driven to extend and retract, thereby driving the subsequent structure to slide. The driving end of the pneumatic push rod 14 is fixedly connected to a sliding plate 15. The sliding plate 15 can increase the contact area of the pneumatic push rod 14, thereby driving multiple subsequent structures to slide at the same time. The internal sliding connection of the sliding clamping block 12 is two sliding plates 16. Two inclined grooves 20 are provided on the adjacent sides of the two sliding plates 16. The function of the inclined grooves 20 is to convert the horizontal movement of the sliding plate 15 into the horizontal movement of the sliding plate 2 16 through contact with the sliding plate 15, thereby realizing the clamping action. The interior of the sliding clamping block 12 is fixedly connected with multiple conduits 2 18, and the exterior of the multiple conduits 2 18 is slidably connected with multiple clamping plates 17. The conduits 2 18 can ensure that the clamping plates 17 can slide smoothly on the exterior thereof, while maintaining a certain degree of fitting accuracy to prevent the clamping plates 17 from shaking or deflecting during the sliding process, thereby playing a guiding role. A spring 19 is sleeved on the exterior of the conduits 2 18, one end of the spring 19 is fixedly connected to the exterior of the clamping plates 17, and the other end of the spring 19 is fixedly connected to the interior of the sliding clamping block 12. When the pneumatic push rod 14 pushes the sliding plate 15, thereby driving the sliding plate 2 16 and the clamping plate 17 to move toward the preform, the spring 19 is compressed, and its stored elastic potential energy enables the clamping plate 17 to apply a moderate and uniform clamping force to the preform. At the same time, when the clamping is released, the spring 19 can quickly pull the clamping plate 17 back to its initial position, preparing for the next clamping operation.
[0033] Working Principle: First, the operator turns on the power of the electric slide 2 to control the sliding position of the slide block 3. Then, the power switch of the hydraulic rod 4 is turned on, causing the driving end to extend downward, driving the bottom structure to clamp and unload the material. Simultaneously, the power of the electric push rod 7 is turned on again. The driving end of the electric push rod 7 extends, driving the connecting column 8 to pull the slide plate 9 to slide. This causes the multiple inclined guide grooves 10 on the slide plate 9 to control the sliding of the knob 13. This in turn drives the sliding clamping blocks 12 to slide outside the guide tube 11, adjusting the distance between the multiple sliding clamping blocks 12. The electric slide 2 can precisely control the position of the slide block 3, allowing the device to operate at different spatial coordinate points. Whether it is for picking up or placing preforms, high-precision positioning is achieved. This is crucial for preform handling operations that require precise docking at specific locations on the production line. It effectively reduces operational errors caused by positional deviations, improves the accuracy of preform clamping and unloading, and ensures that each preform is accurately placed in the predetermined position, thus meeting the different positioning requirements of preforms at the pick-up and placement locations.
[0034] Secondly, the multiple sliding clamping blocks 12 on the rear side of the pitch change fall to the outside of the bottle blank. At this time, the power switch of the pneumatic push rod 14 is turned on, and the driving end of the pneumatic push rod 14 extends to drive the bottom sliding plate 15 to slide downward, thereby pushing the two sliding plates 2 16 to slide downward. Since the inclined groove 20 of the sliding plate 2 16 contacts the clamping plate 17, the clamping plate 17 is pushed to slide horizontally, stretching the spring 19 on the rear side. When the multiple clamping plates 17 slide toward the adjacent side, the internal tooth grooves clamp the outside of the bottle blank, and then follow the top control component and pitch change component to move and place it in other places. The spacing can also be adjusted according to the actual size of the bottle blank to ensure that each sliding clamping block 12 can be accurately positioned in the appropriate position. This precise clamping method greatly improves the stability and reliability of clamping, avoids the bottle blank from shaking or slipping during transportation, and ensures that the bottle blank can be safely and accurately moved to the designated position, thereby improving the accuracy and stability of the entire production process and reducing production accidents and product damage caused by improper clamping.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
