Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production technology, and in particular to a plastic beverage bottle edge trimming device. Background Technology

[0002] In the production process of plastic beverage bottles, molding processes such as blow molding and injection molding are the core links. However, the molded bottles often have excess flash, burrs or irregular protrusions due to problems such as mold closing accuracy deviation, uneven material flow, and inconsistent cooling shrinkage.

[0003] Currently, the industry's method for handling edge defects in plastic beverage bottles is to manually trim them using handheld trimming tools (such as utility knives or specialized trimming knives). This method relies on the operator's experience and skill, resulting in extremely low trimming efficiency, making it difficult to adapt to the pace of large-scale, assembly-line production. Furthermore, human error can easily lead to unevenness in the smoothness of the trimmed bottle edges, and in some cases, over-trimming can damage the bottle's structure.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a plastic beverage bottle edge trimming device, making it more industrially valuable. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a plastic beverage bottle edge trimming device.

[0006] This utility model discloses a plastic beverage bottle edge trimming device, including a conveyor belt for conveying the bottle, a supporting workbench placed in the space below the conveyor belt, and movable plates that can be raised and lowered are movably installed at the four corners of the workbench via guide rods. Two sets of motors that can move inward synchronously are installed on the movable plates. The output shaft of each motor passes through the movable plate and is connected to a drive plate. The drive plate is in contact with the edge of the bottle to drive the bottle to rotate. A height-adjustable limiting plate is fixed on one side of the movable plate. The limiting plate is located on one side of the drive plate. The space between the limiting plate and the two drive plates is used to limit the bottle. A trimming head that can contact the bottle is installed below the movable plate.

[0007] In this plastic beverage bottle edge trimming device, a conveyor belt continuously transports the bottles to be trimmed, stably moving them to the trimming station. A supporting workbench placed beneath the conveyor belt provides a stable foundation for the entire device. Liftable movable plates, mounted at the four corners of the workbench via guide rods, can adjust their position according to the bottle height to accommodate trimming needs of different bottle sizes. Two sets of motors mounted on the movable plates move inward synchronously, allowing the output shafts to pass through the drive discs mounted behind the movable plates and precisely align with the bottle edge. Driven by the motors, the drive discs rotate the bottle at a uniform speed, ensuring even trimming. A height-adjustable limiting plate fixed to one side of the movable plate can be adjusted to accommodate the limiting requirements of different bottles. Located on the side of the drive discs, the space between the limiting plate and the two drive discs limits the rotation of the bottle, preventing bottle displacement and ensuring trimming accuracy. A trimming head mounted below the movable plate contacts the bottle edge during rotation, trimming excess burrs and flash.

[0008] Furthermore, the limiting plate is fixed on the adapter plate, and the adapter plate is installed in the vertically set oblong hole of the positioning plate by bolts and nuts. The top of the positioning plate has a horizontal oblong hole, and the positioning plate is installed in the screw hole on the end face of the movable plate by bolts.

[0009] The limiting plate for limiting the bottle is fixed on the adapter plate. The adapter plate is installed in the vertically set oblong hole of the positioning plate by bolts and nuts. With the help of the structure of the vertical oblong hole, the vertical position of the adapter plate on the positioning plate can be adjusted, thereby realizing the height adjustment of the limiting plate to adapt to the limiting requirements of bottles of different heights. The top of the positioning plate has a horizontal oblong hole. The positioning plate is installed by bolting through the horizontal oblong hole and screwing into the screw hole on the end face of the movable plate. The horizontal oblong hole can adjust the horizontal position of the positioning plate on the end face of the movable plate, thereby driving the limiting plate to move horizontally and ensuring that a limiting space adapted to the bottle size is formed between the limiting plate and the drive plate.

[0010] Furthermore, two motors are respectively mounted on corresponding movable plates. The movable plates are movably mounted on the surface of the movable plates via slide rails and sliders. A support is installed on one side of the movable plate, and a rotating rod is movably mounted in the support via bearings. A drive tooth is fixed at the end of the rotating rod. Two racks are installed on the side of the two movable plates near the drive tooth, and the two racks mesh with the drive tooth vertically.

[0011] Two motors are mounted on corresponding movable plates. The movable plates are movably mounted on the surface of the movable plates via slide rails and sliders, allowing the movable plates to slide smoothly along the surface of the movable plates. A support is installed on one side of the movable plate, providing stable support for the rotating rod. The rotating rod, which is movably mounted in the support via bearings, can rotate flexibly. A drive tooth is fixed at the end of the rotating rod. When the rotating rod rotates, it drives the drive tooth to rotate synchronously. Two racks are installed on the side of the two movable plates near the drive tooth, which are staggered vertically. The two racks mesh with the drive tooth vertically. When the drive tooth rotates, it can drive the two movable plates to move synchronously in opposite directions through the meshing action with the two racks, thereby realizing the synchronous approach or departure of the two motors to adapt to the driving needs of bottles with different diameters.

[0012] Furthermore, a top plate is installed at the top of the guide rod, and a through screw is movably installed on the top plate via a bearing. A screw sleeve that mates with the screw is fixed on the movable plate, and the top of the screw is connected to the lifting motor via a belt pulley.

[0013] A top plate is installed at the top of the guide rod. The top plate not only stabilizes and limits the top of the guide rod, but also provides a mounting base for the screw. A through screw is movably mounted on the top plate via bearings. The bearings allow the screw to rotate flexibly on the top plate. A threaded sleeve that mates with the screw is fixed on the movable plate. When the screw rotates, it drives the movable plate to move up and down along the guide rod through the threaded engagement with the threaded sleeve. The top of the screw is connected to the lifting motor via a belt and pulley. After the lifting motor is started, it drives the screw to rotate synchronously through the transmission action of the belt and pulley, thereby realizing the automated control of the lifting action of the movable plate to adapt to the trimming needs of bottles of different heights.

[0014] Furthermore, the trimming head includes a trimming cutter head that contacts the surface of the bottle. The trimming cutter head is fixed on a cutter holder, which is installed in the waist-shaped groove of the connecting plate by bolts and nuts. The tail end of the connecting plate is fixedly connected to the upright plate. The upper end of the upright plate is provided with a waist-shaped groove, and the upper end of the upright plate is fixedly connected to the side of the movable plate by bolts.

[0015] The trimming head includes a trimming blade that directly contacts the bottle surface to perform edge trimming operations. The trimming blade is fixed on a blade holder, which is installed in a slotted groove on a connecting plate using bolts and nuts. The slotted groove allows adjustment of the blade holder's position on the connecting plate, thereby changing the horizontal or vertical position of the trimming blade to suit different bottle edge trimming needs. The tail end of the connecting plate is fixedly connected to a vertical plate, which provides mounting support for the connecting plate and the trimming blade. A slotted groove is provided at the upper end of the vertical plate, through which bolts are used to fix the upper end of the vertical plate to the side of a movable plate. The slotted groove at the upper end of the vertical plate allows adjustment of the vertical plate's installation height on the side of the movable plate, further optimizing the contact position between the trimming blade and the bottle edge to ensure trimming effectiveness.

[0016] Furthermore, two parallel downward-extending mounting rods are fixed below the movable plate. Each mounting rod has multiple screw holes. Bolts pass through the waist-shaped groove in the middle of the guide plate and are screwed into the screw holes. There is a guide rod at the top of the guide plate.

[0017] Two parallel downward-extending mounting rods are fixed below the movable plate. The mounting rods provide a stable carrier for the installation of the guide plate. Each mounting rod has multiple screw holes. The bolts pass through the waist-shaped groove in the middle of the guide plate and are screwed into the screw holes. By cooperating with the waist-shaped groove and different screw holes, the vertical and horizontal positions of the guide plate on the mounting rods can be flexibly adjusted. There is a guide rod at the top of the guide plate. The guide rod can guide the bottle before it is transported to the trimming station, ensuring that the bottle accurately enters the limiting space between the limiting plate and the drive plate, and avoiding bottle deviation that would affect the trimming operation.

[0018] Furthermore, guide frames are installed on both sides of the conveyor belt to guide the movement of the bottles, and a material box is located at the end of the conveyor belt.

[0019] The conveyor belt used for transporting bottles to be repaired and after repair is equipped with guide frames on both sides to guide the movement of the bottles. The guide frames can limit and guide the bottles transported on the conveyor belt to prevent the bottles from deviating from the conveyor belt or the preset transport path during the transport process, ensuring that the bottles are transported stably and accurately to the repair station. A material box is set at the end of the conveyor belt. When the repaired bottles are transported to the end of the conveyor belt, they can fall directly into the material box to achieve centralized collection of the repaired bottles.

[0020] By means of the above-described solution, the present invention has at least the following advantages:

[0021] This plastic beverage bottle edge trimming device effectively solves the problems of low efficiency, poor quality, and insufficient adaptability of existing manual trimming technologies, and has many significant advantages:

[0022] Firstly, the conveyor belt enables automated conveying of bottles, and the guide frames on both sides of the conveyor belt ensure that the bottles do not deviate during the conveying process. There is no need for manual handling and transfer, which greatly reduces human intervention and significantly improves overall production efficiency. It is suitable for large-scale, assembly line production rhythm. At the same time, the material box at the end of the conveyor belt can collect the trimmed bottles in a centralized manner to avoid the bottles from scattering and being damaged, and reduce subsequent handling costs.

[0023] Secondly, with the help of a liftable movable plate, a motor that can move closer or further away synchronously, and a limit plate with adjustable height and horizontal position, it can flexibly adapt to plastic beverage bottles of different heights and diameters without the need for frequent disassembly and replacement of parts, greatly improving the versatility and adaptability of the device and reducing the cost of equipment replacement and debugging.

[0024] Third, the bottle body is rotated at a constant speed by the drive plate, and the stable limiting space formed by the limiting plate and the two drive plates ensures that the bottle body does not shake or deviate during the trimming process. At the same time, the trimming blade can be adjusted in position in the waist-shaped groove of the connecting plate and the waist-shaped groove of the upright plate through the blade holder, so as to accurately fit the edge of the bottle body. This avoids the problem of uneven trimming flatness or over-trimming that damages the bottle body structure caused by human operation error, and significantly improves the quality and consistency of bottle edge trimming, meeting the safety standards and appearance requirements of food packaging containers.

[0025] Fourth, the guide rod under the moving plate can accurately guide the bottle before it enters the trimming station, ensuring that the bottle accurately enters the limit space, further ensuring that the trimming operation is carried out stably and orderly. The overall device structure is reasonably designed, and the components work together to realize the automation, precision and high adaptability of bottle edge trimming, which has extremely high industrial utilization value.

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] See Figure 1 and Figure 2 The plastic beverage bottles to be repaired are placed on conveyor belt 1, which steadily transports the bottles to the repair station. A support workbench 2, placed below conveyor belt 1, provides a stable foundation for the entire device. Movable plates 4, mounted on the four corners of the workbench 2 via guide rods 3, are first adjusted to the appropriate position according to the bottle height. Then, two sets of motors 5, mounted on the movable plates 4 and capable of moving inwards synchronously, drive the output shafts through the movable plates 4 to the drive discs 6, which then move towards the bottle, ensuring a tight fit between the drive discs 6 and the bottle edge. Simultaneously, a height-adjustable limiting plate 7 (already adjusted to the appropriate position according to the bottle height), fixed on one side of the movable plates 4, cooperates with the two drive discs 6 to create a limiting space for the bottle, preventing it from shifting. Then, the motors 5 start, driving the drive discs 6 to rotate, and... The bottle rotates at a constant speed. At this time, the trimming head installed below the movable plate 4 contacts the edge of the rotating bottle and trims the excess burrs and flash on the edge of the bottle. After trimming, the conveyor belt 1 continues to transport the bottle away from the trimming station. The conveyor belt 1 realizes automated conveying of the bottle without manual handling, improving conveying efficiency. The height-adjustable movable plate 4 can adapt to bottles of different heights, and the synchronously moving motor 5 and drive plate 6 can adapt to bottles of different diameters. The height-adjustable limit plate 7 ensures that bottles of different specifications can be stably limited during trimming to avoid deviation. The bottle rotates at a constant speed under the drive plate 6 to cooperate with the trimming head, ensuring trimming uniformity and accuracy. It effectively solves the problems of low efficiency, poor quality and insufficient adaptability of manual trimming, greatly improves the overall trimming efficiency and quality, and meets the needs of large-scale production.

[0037] See Figure 3 and Figure 4Before the plastic beverage bottle edge trimming device operates, the limiting structure is adjusted according to the height and diameter specifications of the bottle to be trimmed: the limiting plate 7, used to limit the bottle, is fixed on the adapter plate 8. By loosening the bolts and nuts between the adapter plate 8 and the positioning plate 9, and using the vertically set oblong hole on the positioning plate 9, the adapter plate 8 is moved up and down to adjust the height of the limiting plate 7 to match the height of the bottle. Then, the bolts and nuts are tightened to fix it. Next, the bolts between the positioning plate 9 and the movable plate 4 are loosened. Using the horizontal oblong hole at the top of the positioning plate 9, the positioning plate 9 is moved horizontally (the positioning plate 9 is installed in the screw hole on the end face of the movable plate 4 by bolts). This causes the limiting plate 7 to move horizontally, so that the limiting plate 7 and the two drive discs 6 form a limit that matches the diameter of the bottle. After the space is adjusted, tighten the bolts to fix the positioning plate 9. During operation, the limiting plate 7 and the drive disc 6 work together to stably limit the rotating bottle body, preventing the bottle body from shifting and affecting the trimming accuracy. The height of the limiting plate 7 can be adjusted by the movement of the adapter plate 8 in the vertical waist-shaped hole of the positioning plate 9. The horizontal position of the limiting plate 7 can be adjusted by the movement of the positioning plate 9 on the movable plate 4 with the help of the horizontal waist-shaped hole. It can adapt to bottles of different heights and diameters without replacing the limiting-related components, which improves the adaptability of the device to bottles of multiple specifications. Moreover, the adjustment operation is simple and convenient, and the parameter adjustment can be quickly completed to meet production needs. At the same time, the stable fixing method ensures that the limiting plate 7 does not loosen during operation, ensuring the bottle body limiting effect and further improving the stability of trimming quality.

[0038] See Figure 2 and Figure 5First, the rotating rod 12, which is movably mounted on the support 11 of the movable plate 4 with the help of bearings, is driven to rotate by external force. The drive tooth 13 fixed at the end of the rotating rod 12 rotates synchronously with the rotating rod 12. Since the two movable plates 10, which are respectively equipped with motors 5, have racks 14 that are staggered up and down on the side near the drive tooth 13, and the two racks 14 mesh with the drive tooth 13 up and down respectively, when the drive tooth 13 rotates, it will drive the two racks 14 to move in opposite directions, thereby driving the two movable plates 10 to slide smoothly on the surface of the movable plate 4 through the movable mounting structure of the slide rail slider, so that the motors 5 on the two movable plates 10 move closer or further away synchronously until the drive disk 6 on the output shaft of the motor 5 can accurately fit with the edge of the bottle to be repaired. During operation, motor 5 starts and drives drive disk 6 to rotate, which in turn drives the bottle to rotate at a constant speed to cooperate with the trimming head operation. The advantages of this structure are: through the meshing transmission of drive gear 13 and upper and lower staggered racks 14, the two moving plates 10 and motor 5 can be moved synchronously, ensuring that the two drive disks 6 are in consistent contact with the edge of the bottle, avoiding unstable rotation of the bottle due to excessive tightness or looseness on one side. At the same time, the moving plate 10 slides on the surface of the movable plate 4 through the slide rail slider, ensuring smooth and stable movement and reducing jamming. Moreover, there is no need to manually adjust the position of the two motors 5 separately, making the operation convenient and efficient. It can quickly adapt to the driving needs of bottles with different diameters, improving the adaptability and working stability of the device for multiple bottle specifications.

[0039] See Figure 5When the plastic beverage bottle edge trimming device adjusts the position of the movable plate 4 according to the height of the bottle to be trimmed, the relevant drive structure above the top plate 15 installed at the top of the guide rod 3 is activated. The lifting motor 18, which is connected to the top of the screw 16 via a belt and pulley, starts to work. The lifting motor 18 drives the through screw 16, which is movably installed on the top plate 15 via a bearing, to rotate synchronously through the transmission action of the belt and pulley. Since the movable plate 4 is fixed with a screw sleeve 17 that cooperates with the screw 16, the screw 16 will form a threaded transmission with the screw sleeve 17 when it rotates, thereby driving the movable plate 4 to rise and fall smoothly along the guide rods 3 at the four corners above the worktable 2 until the trimming head, drive plate 6 and limit plate 7 below the movable plate 4 are adjusted to a position that matches the height of the bottle to be trimmed. Then the lifting motor 18 stops working. During operation, the top plate 15 provides a stable limit to the top of the guide rod 3, preventing the guide rod 3 from shaking and affecting the stability of the movable plate 4. The advantages of this structure are: the movable plate 4 is automatically raised and lowered through the cooperation of the lifting motor 18, belt pulley, screw 16 and screw sleeve 17, without the need for manual adjustment. It is convenient to operate and can accurately control the lifting height of the movable plate 4, ensuring the accurate relative position of the trimming head, drive plate 6 and bottle body, adapting to the trimming needs of bottles of different heights. At the same time, the guide rod 3 provides guidance for the lifting and lowering of the movable plate 4, ensuring that the lifting and lowering process of the movable plate 4 is smooth and does not deviate. The top plate 15 further improves the stability of the installation of the guide rod 3 and screw 16. The overall structure improves the automation level and working stability of the device and reduces the intensity of manual operation.

[0040] Meanwhile, after the bottle body is processed, the lifting motor 18 drives the entire movable plate 4 to move upward, so that the drive disc 6 and the trimming head that are in contact with the bottle body are separated from the bottle body, and the bottle body is moved away from the processing station by the conveyor belt 1.

[0041] See Figure 6Since the trimming cutter head 19 in the trimming head is fixed on the cutter holder 20, and the cutter holder 20 is installed in the waist-shaped groove of the connecting plate 21 by bolts and nuts, the position of the cutter holder 20 can be adjusted along the waist-shaped groove by loosening the corresponding bolts and nuts, thereby changing the horizontal or vertical position of the trimming cutter head 19; since the tail end of the connecting plate 21 is fixedly connected to the upright plate 22, and the upper end of the upright plate 22 has a waist-shaped groove and is fixed to the side of the movable plate 4 by bolts, the height of the upright plate 22 can be adjusted along the waist-shaped groove at the upper end of the upright plate 22 by loosening the bolts, further optimizing the contact position between the trimming cutter head 19 and the edge of the bottle. After adjustment, all bolts and nuts are tightened for fixation; during operation, when the bottle is driven Driven by the rotating disc 6, the trimming head 19, which is in contact with the bottle surface, can precisely trim excess burrs and flash on the bottle edge. By adjusting the cutter holder 20 in the waist-shaped groove of the connecting plate 21 and adjusting the height of the upright plate 22 on the side of the movable plate 4, the position of the trimming head 19 can be flexibly changed to adapt to the trimming needs of different bottle sizes. It can handle edge defects in different locations without replacing the trimming head 19, making it convenient to operate and reducing replacement costs. At the same time, the stable fixed structure ensures that the trimming head 19 does not shake during operation, ensuring trimming accuracy and consistency, and avoiding problems such as incomplete trimming or damage to the bottle due to the position deviation of the cutter head.

[0042] See Figure 6 Two parallel downward-extending mounting rods 23 are fixed below the movable plate 4. The operator loosens the bolts that pass through the waist-shaped groove in the middle of the guide plate 24 and screw into the screw holes of the mounting rods 23. By cooperating with the waist-shaped groove and different screw holes, the vertical and horizontal positions of the guide plate 24 on the mounting rods 23 are adjusted so that the guide rod 25 at the top of the guide plate 24 can match the path of the bottles conveyed on the conveyor belt 1. After adjustment, the bolts are tightened to fix the guide plate 24. During operation, the conveyor belt 1 moves the bottles to be repaired towards the repair station. When the bottle approaches the repair station, the guide rod 25 first contacts the bottle, guiding it. The system ensures the bottle body accurately enters the limiting space between the limiting plate 7 and the two drive discs 6, preventing bottle body displacement from affecting subsequent driving and trimming operations. Through the cooperation of multiple screw holes on the mounting rod 23 and the waist-shaped groove of the guide plate 24, the position of the guide rod 25 can be flexibly adjusted to adapt to the guiding needs of bottles with different diameters and heights. It can adapt to various production scenarios without replacing the guide components, and the operation is simple and convenient. At the same time, the precise guiding effect of the guide rod 25 reduces the problem of trimming station docking failure caused by bottle body displacement, improves the continuity and stability of the device operation, and further ensures the accuracy and efficiency of bottle edge trimming.

[0043] The plastic beverage bottles to be repaired are placed on the conveyor belt 1 used to transport the bottles. After the conveyor belt 1 is started, it moves the bottles towards the repair station. During the process, the guide frames 26 installed on both sides of the conveyor belt 1 will limit the movement of the bottles to prevent them from deviating from the preset transport path due to shaking or external force. This ensures that the bottles are transported stably and accurately to the repair station. The drive plate 6, limit plate 7 and repair head under the movable plate 4 work together to complete the edge repair operation. After the repair is completed, the conveyor belt 1 continues to move the bottles towards the end of the conveyor. When the bottles reach the end of the conveyor belt 1, they will fall into the material box 27 set at the end of the conveyor belt 1 under their own gravity, realizing the centralized collection of the repaired bottles.

[0044] The working principle of this utility model is as follows:

[0045] Combined with appendix Figure 1-6 The complete process of the bottle from entering the working station to collection after repair in this device is as follows: First, the plastic beverage bottle to be repaired is placed on the conveyor belt 1. The guide frames 26 on both sides of the conveyor belt 1 limit and guide the bottle to prevent it from deviating during transport. At the same time, the guide plate 24 on the guide rod 23 below the movable plate 4 and the guide rod 25 at the top of the guide plate 24 further guide the bottle precisely as it approaches the repair station, ensuring that the bottle enters the limiting space formed by the limiting plate 7 and the two drive plates 6 smoothly. At this time, the bottle officially arrives at the working station. Next, the movable plate 4, which has been adjusted in advance according to the bottle specifications (driven by the lifting motor 18 on the top plate 15 through the belt pulley to rotate the screw 16, and driven by the screw sleeve 17 to rise and fall along the guide rod 3 to the appropriate height), remains stable. The motor 5 starts and drives the drive plate 6 to rotate (the motor 5 drives the sliding plate 10 on the slide rail slider). The gear 13 meshes with the rack 14 to adjust the position, thereby driving the bottle to rotate at a constant speed. At the same time, the trimming cutter 19 fixed by the side plate 22, connecting plate 21 and cutter holder 20 of the movable plate 4 contacts the edge of the bottle to complete the trimming of excess burrs and flash. After trimming, the lifting motor 18 starts again, and through the transmission action of the belt pulley, screw 16 and screw sleeve 17, it drives the movable plate 4 to move upward along the guide rod 3, so that the drive plate 6 and the trimming cutter 19 simultaneously disengage from the bottle, releasing the limitation and contact on the bottle. Finally, the conveyor belt 1 continues to run, driving the trimmed bottle forward. When the bottle is conveyed to the end of the conveyor belt 1, it falls into the material box 27 set at the end of the conveyor belt 1 under its own gravity, realizing the centralized collection of the bottle. Thus, the whole process from the bottle entering the work station, trimming, moving up the movable plate to the bottle leaving the collection point is completed.
