Description
Technical Field
[0001] The utility model relates to the technical field of trimmers, in particular to a blow molding trimmer for plastic bottles. Background Art
[0002] A blow molding trimmer for plastic bottles is a device specifically designed to trim blow-molded plastic bottles. While blow molding can quickly produce plastic bottles, it often creates surface defects such as burrs and unevenness. In these cases, a blow molding trimmer is needed to further process the plastic bottles to improve their quality and appearance. This device can significantly improve the quality of plastic bottle production. Precise trimming removes surface defects, resulting in more accurate dimensions and a smoother, more aesthetically pleasing appearance, thus meeting market demand for high-quality plastic bottles.
[0003] Existing blow molding trimmers for plastic bottles typically consist of several key components: a trimming tool system, a clamping device, a transmission mechanism, and a control system. The trimming tool system typically includes rotating and cutting tools, used to remove burrs and irregularities from the bottle's surface. The clamping device secures the bottle, ensuring its stable position during the trimming process. The transmission mechanism drives the tool system and clamping device. The control system manages the entire operation of the equipment, including adjusting the tool's cutting parameters and controlling the clamping force of the clamping device.
[0004] However, conventional blow molding trimmers for plastic bottles typically utilize arc-shaped clamps to clamp the outer wall of the plastic bottle. This clamping method has significant limitations. First, for relatively regular-shaped plastic bottles, the arc-shaped clamps can provide a certain clamping force. However, for irregular-shaped plastic bottles, the arc-shaped clamps have difficulty fully conforming to the outer wall due to their irregular surface shapes, resulting in a lower clamping force. Furthermore, the arc-shaped clamps occupy a certain amount of space when clamping the outer wall of the plastic bottle, blocking part of the outer wall of the plastic bottle. The trimming components cannot fully contact the blocked area, which reduces the trimming accuracy and efficiency. Therefore, a blow molding trimmer for plastic bottles is proposed to address the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment of a blow molding trimmer for plastic bottles, comprising a working chamber 1, a trimming robot arm 5 fixedly connected to the inner wall of the working chamber 1, a fixing component provided inside the working chamber 1, the fixing component being used to fix the plastic bottle, and a collecting component provided on the outer wall of the working chamber 1, the collecting component being used to collect plastic debris;
[0035] The fixing assembly includes a plurality of rubber splints 15, which are made of high-quality, highly elastic rubber material. This rubber has good flexibility and wear resistance, and can provide moderate cushioning when in contact with the inner wall of the plastic bottle to avoid scratching or damaging the plastic bottle. The surface of the rubber splint 15 has been specially treated and has a certain anti-slip texture, which can increase the friction with the inner wall of the plastic bottle and further improve the stability of the clamping. The rubber splint 15 is arranged inside the working bin 1, and the bottom of the inner wall of the working bin 1 is fixedly connected to the arc bottom plate 6, the top of the arc bottom plate 6 is fixedly connected to the motor 8, and the output end of the motor 8 is fixedly connected to the connecting plate 9, which is made of high strength It is made of stainless steel material, and the surface is precisely processed to ensure its flatness and verticality, reducing the jumping and friction during rotation. A plurality of slide grooves 10 are opened inside the connecting plate 9, and a plurality of connecting blocks 11 are set on the top of the connecting plate 9. The connecting block 11 is made of high-strength plastic material with good corrosion resistance and insulation performance. The inside of the connecting block 11 is fixedly connected with a slide bar 12, and the slide bar 12 is slidably connected to the inner wall of the slide groove 10. One side of the connecting block 11 is fixedly connected with a connecting block 2 13, and the inside of the connecting block 2 13 is fixedly connected with a plurality of spring telescopic rods 14, and the output end of the spring telescopic rod 14 is fixedly connected to the outer wall of the rubber splint 15.
[0036] Specifically, in the process of the device clamping the plastic bottle, the inner wall of the plastic bottle is first gradually brought close to the outer wall of the rubber splint 15, and then the motor 8 is started, and the output end of the motor 8 is used to drive the connecting plate 9 to rotate. While the connecting plate 9 rotates, it drives the connecting block 11 on the outer wall of the slide bar 12 to expand outward through the slide groove 10. While the connecting block 11 moves, it drives the connecting block 2 13 to move synchronously. While the connecting block 2 moves, it drives the rubber splint 15 to squeeze the inner wall of the plastic bottle through the spring telescopic rod 14. At the same time, the special-shaped surface of the inner wall of the plastic bottle provides a reaction force to the multiple rubber splints 15 , thereby pushing the spring telescopic rod 14 to compress. This reaction force enables the rubber splint 15 to fit the irregular surface of the inner wall of the plastic bottle more closely, increasing the contact area between the rubber splint 15 and the irregular surface of the plastic inner wall, thereby enhancing the fixing effect of the rubber splint 15 on the plastic bottle. Such a clamping method can not only ensure the stability of the plastic bottle during the trimming process, but also facilitate the trimming of the outer wall of the plastic bottle by the trimming robot arm 5. Since the rubber splint 15 is located on the inner wall of the plastic bottle, it will not block the outer wall of the plastic bottle, thereby avoiding affecting the trimming of the outer wall of the plastic bottle by the trimming robot arm 5, thereby improving the quality and efficiency of the trimming.
[0037] Reference Figure 1 、 Figure 4 and Figure 5 , the collection component includes a baffle 3, which is arranged on the outer wall of the working bin 1. The baffle 3 is made of a thick stainless steel plate, has high strength and stability, and can effectively block plastic debris. A collection groove 7 is opened inside the arc-shaped bottom plate 6. The arc-shaped bottom plate 6 is made of smooth stainless steel material and has good flow-conducting performance, which can smoothly guide the debris into the collection groove 7. Card balls 24 are provided on both sides of the baffle 3. A spring column 23 is fixedly connected to one side of the card ball 24. The outer wall of the spring column 23 is fixedly connected to a slider 2. The slider 2 is made of high-strength aluminum alloy with good wear resistance and corrosion resistance. The slider 2 is fixedly connected to both sides of the working bin 1. The outer wall of the baffle 3 is fixedly connected to a handle 4, which is made of a strong plastic material. The surface is anti-slip treated, has a good grip, and is convenient for the operator to push hard. The work bin 1 is fixedly connected to a filter 22, and the outer wall of the work bin 1 is fixedly connected to a fixed block 16. The fixed block 16 is fixedly connected to an electric telescopic rod 17. The output end of the electric telescopic rod 17 is fixedly connected to a connecting shell 18. The inner wall of the connecting shell 18 is fixedly connected to a fan 19. The fan 19 is arranged on one side of the filter 22. The connecting shell 18 is internally slidably connected to a limit strip 20. The limit strip 20 is made of stainless steel, has high strength and straightness, and can accurately limit the movement of the connecting shell 18. Both ends of the limit strip 20 are fixedly connected to fixed blocks 21, and the fixed block 21 is fixedly connected to the outer wall of the work bin 1.
[0038] Specifically, in the process of collecting plastic trimming waste by the equipment, first hold the handle 4, and by holding the handle 4, push the baffle 3 to slide on the inner wall of the slider 2. When the baffle 3 has blocked the feed inlet inside the working bin 1, the card ball 24 moves to the internal card slot of the baffle 3, and the rebound force of the spring column 23 pushes the card ball 24 to be stuck in the card slot inside the baffle 3, thereby fixing the position of the baffle 3. In this way, the baffle 3 can firmly isolate the plastic debris from the inside of the working bin 1 to prevent the debris from splashing out and affecting the working environment. Then start the electric telescopic rod 17, and use the output end of the electric telescopic rod 17 to drive the connecting shell 18 to slide on the outer wall of the limit bar 20. While moving, the connecting shell 18 will drive the fan 19 to slide on the outer wall of the filter screen 22, and the wind force generated by the fan 19 is transmitted to the inside of the working bin 1 through the filter screen 22, and the filter screen 22 is used to realize air circulation inside the working bin 1. At the same time, filter 22 isolates and filters debris within work chamber 1, preventing it from dispersing into the air with the airflow. The wind generated by fan 19 blows the plastic debris into collection trough 7. The concave surface of the outer wall of curved bottom plate 6 conveniently guides the debris into collection trough 7. The water within collection trough 7 absorbs the plastic debris, preventing it from being released into the air. The water effectively absorbs the plastic debris, causing it to settle at the bottom of collection trough 7, thereby improving the device's collection efficiency for plastic debris.
[0039] Working principle: When the equipment is clamping the plastic bottle, the inner wall of the plastic bottle is moved to the outer wall of the rubber splint 15, and then the motor 8 is started, and the output end of the motor 8 is used to drive the connecting plate 9 to rotate. While the connecting plate 9 is rotating, it drives the connecting block 11 on the outer wall of the slide 12 to expand outward through the slide groove 10. While the connecting block 11 is moving, it drives the connecting block 2 13 to move synchronously. While the connecting block 2 13 is moving, it drives the rubber splint 15 to squeeze the inner wall of the plastic bottle through the spring telescopic rod 14. At the same time, the special-shaped surface of the inner wall of the plastic bottle is exposed to multiple rubber splints. 15 provides a reaction force, thereby pushing the spring telescopic rod 14 to compress, so that the rubber splint 15 fits the inner wall of the plastic more closely, increases the contact area between the rubber splint 15 and the irregular surface of the inner wall of the plastic, and enhances the fixing effect of the rubber splint 15 on the plastic bottle. At the same time, it is convenient for the trimming robot arm 5 to trim the outer wall of the plastic, and avoids the clamping parts blocking the outer wall of the plastic, thereby affecting the trimming of the outer wall of the plastic by the trimming robot arm 5. When the equipment is collecting plastic trimming waste, hold the handle 4 to push the baffle 3 to slide on the inner wall of the slider 2. When the baffle 3 After the internal feed port of the working bin 1 is blocked, the card ball 24 moves to the internal card slot of the baffle 3, and the rebound force of the spring column 23 is used to push the card ball 24 to be stuck in the card slot inside the baffle 3, thereby fixing the position of the baffle 3, and using the baffle 3 to isolate the plastic debris inside the working bin 1, and then start the electric telescopic rod 17, and use the output end of the electric telescopic rod 17 to drive the connecting shell 18 to slide on the outer wall of the limit bar 20, and use the limit bar 20 to limit the movement of the connecting shell 18. While the connecting shell 18 moves, it will drive the fan 19 to filter The outer wall of the net 22 slides, and the wind force generated by the fan 19 is transmitted to the interior of the working bin 1 through the filter net 22. The filter net 22 is used to realize air circulation inside the working bin 1, and the filter net 22 is used to isolate and filter the debris inside the working bin 1. The wind force generated by the fan 19 blows the plastic debris into the interior of the collection tank 7. The concave surface of the outer wall of the arc-shaped bottom plate 6 can conveniently guide the debris into the interior of the collection tank 7. The water inside the collection tank 7 is used to adsorb the plastic debris to prevent it from being dissipated in the air, thereby improving the equipment's collection efficiency of plastic debris.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
