Description

Technical Field

[0001] This utility model belongs to the field of blow molding bottle preform technology, and in particular relates to an automatic tail-cutting tool for blow molding bottle preforms. Background Technology

[0002] Blow molding preforms are semi-finished raw materials used in the blow molding process. They are typically pre-injected tubular or cylindrical plastic preforms and are key basic components for manufacturing various hollow plastic containers such as beverage bottles, daily chemical packaging bottles, and food cans. They are mainly made of thermoplastic plastics such as polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP), and have good plasticity and melt flowability.

[0003] The existing automatic tail-cutting fixture for blow-molded bottle preforms has the following drawbacks: On the one hand, it may lack an efficient and orderly conveying mechanism in the unloading stage, which can easily lead to the simultaneous accumulation or chaotic unloading of multiple preforms, resulting in problems such as jamming and misalignment, affecting the standardization and stability of the unloading process, and thus interfering with the tail-cutting process to process the preforms one by one in sequence; on the other hand, the coordination between the preform tossing and the tail-cutting operation may not be linked, requiring additional independent control of the cutting process, resulting in unsmooth action connection, long process intervals, and low overall production efficiency.

[0004] To address these issues, we provide an automatic tail-cutting fixture for blow-molded bottle preforms. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic tail-cutting fixture for blow-molded bottle preforms. By coordinating the feeding mechanism and the tail-cutting mechanism, it solves the problems of easy jamming and misalignment during feeding and the lack of smooth connection of cutting actions in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an automatic tail-cutting fixture for blow-molded bottle preforms, comprising a table, a feeding mechanism on the top of the table, and a tail-cutting mechanism on one side of the table. The feeding mechanism includes a connecting seat, a motor fixedly connected to the bottom of the connecting seat, a transmission component fixedly connected to one end of the motor, and a sliding plate movably connected to one side of the transmission component. The table has a groove for cooperating with the sliding plate, and the sliding plate is slidably connected to the table. Evenly distributed actuating components are fixedly connected to the top of the table. The tail-cutting mechanism includes a vertical plate, the top of which is fixedly connected to the bottom of the table. A circular plate and a driven wheel are movably connected to the surface of the vertical plate via a rotating rod. A driving wheel is connected to the surface of the driven wheel via a belt drive. One end of the drive wheel is fixedly connected to the motor, and a shearing component is fixedly connected to the surface of the circular plate. The motor provides power to drive the transmission component, converting the motor's rotational motion into the left-right reciprocating sliding of the slide plate. The slide plate drives the actuating component to push the blow-molded bottle preform to the tail-cutting mechanism. The drive wheel of the tail-cutting mechanism is driven by the motor, and the driven wheel and the circular plate are driven by the belt. The circular plate drives the adjusting rod to rotate, thereby controlling the opening and closing of the shears and realizing automatic cutting of the preform tail. The motor-driven continuous feeding and shearing linkage design can complete the feeding and tail-cutting of the preform without manual intervention, significantly improving production efficiency. The mechanical transmission structure of the actuating component and the shearing component is stable and reliable, adaptable to high-speed assembly line operation, and reduces human operation errors and safety risks.

[0008] The present invention is further configured such that the transmission component includes a rotating plate, one side of which is fixedly connected to a motor, and the other side of which is movably connected to an inclined plate. One side of the inclined plate is movably connected to a sliding plate. The rotating plate of the transmission component is fixed to the output end of the motor, and the other side is movably connected to the sliding plate through the inclined plate. This converts the circular motion of the motor into the linear reciprocating motion of the sliding plate. The crank-slider type transmission structure has a precise motion trajectory, and the travel of the sliding plate can be controlled by adjusting the radius of the rotating plate to adapt to the adjustment of the feeding distance of different specifications of blanks.

[0009] The present invention is further configured such that the actuating component includes an electric telescopic rod, which is disposed through the top of the slide plate. A horizontal plate is fixedly connected to the output end of the electric telescopic rod, and a uniformly distributed actuating plate is fixedly connected to the top of the horizontal plate. The electric telescopic rod of the actuating component drives the horizontal plate to rise and fall, thereby causing the uniformly distributed actuating plates to rise or fall. In conjunction with the lateral movement of the slide plate, the intermittent actuating conveying of the blank is realized. The adjustable height actuating plate design is compatible with blow-molded bottle blanks of different heights, avoiding the problem of material jamming caused by blank stacking.

[0010] The present invention is further configured such that the shearing component includes a connecting frame, one side of which is fixedly connected to a tabletop, and scissors are movably connected to the inner wall of the connecting frame. A limiting groove is formed on the surface of the scissors, and a limiting plate is slidably connected to the inner wall of the limiting groove. A vertical rod is fixedly connected to the bottom of the limiting plate, and an adjusting frame is fixedly connected to the bottom of the vertical rod. An adjusting rod is slidably connected to the inner wall of the adjusting frame, and one end of the adjusting rod is fixedly connected to a circular plate.

[0011] The present invention is further configured such that a limiting sleeve is fixedly connected to the surface of the vertical plate, and a moving groove is provided on the top of the limiting sleeve to cooperate with the movement of the vertical rod. The limiting sleeve is slidably connected to the vertical rod. The circular plate of the shearing piece rotates with the driven wheel, and the vertical rod moves up and down through the adjusting rod. The vertical rod slides in the limiting groove of the shears through the limiting plate, controlling the opening and closing angle of the shears, realizing precise shearing of the tail of the blank, converting the circumferential motion into the opening and closing action of the shears, and the shearing frequency is synchronized with the feeding rhythm.

[0012] The present invention is further configured such that a bracket is fixedly connected to both sides of the top of the table, a fixed frame is fixedly connected to both sides of the bracket, and a material feeding shell is fixedly connected between the fixed frames. The brackets on both sides of the table support the material feeding shell through the fixed frames, which is used to store the blow-molded bottle blanks to be trimmed. The blanks can be guided into the feeding area by gravity or a toggle component. The material feeding shell and the toggle component are precisely matched to achieve orderly feeding of the blanks and avoid the inefficient operation of manually placing them one by one.

[0013] The present invention is further configured such that a support leg is fixedly connected to the bottom of the table, and a stabilizing plate is fixedly connected between the support legs. There are two stabilizing plates, and the support leg at the bottom of the table is connected by two stabilizing plates, which enhances the vibration resistance of the equipment and ensures that the table is stable and does not shake during the tail shearing process. The stabilizing plate design significantly improves the overall rigidity of the equipment and ensures the stability of long-term operation.

[0014] The present invention is further configured such that a rubber pad is fixedly connected to the bottom of the support leg, and the bottom of the rubber pad is provided with anti-slip texture. The rubber pad at the bottom of the support leg has anti-slip texture, which increases the friction with the ground and prevents the equipment from shifting under the action of shearing impact force.

[0015] The present invention has the following beneficial effects.

[0016] 1. The sliding cooperation between the actuating component and the sliding plate of this utility model can move the blow-molded bottle preforms in the feeding shell one by one and in an orderly manner to one side of the tail-cutting mechanism, realizing the automated sequential conveying of the preforms. This avoids the situation of multiple preforms piling up at the same time or being fed in a chaotic manner, ensuring that the tail-cutting process can process the preforms one by one in sequence, improving the standardization and stability of the feeding process, effectively reducing problems such as jamming and misalignment caused by preform stacking, and laying the foundation for the accuracy and continuity of subsequent tail-cutting operations.

[0017] 2. In the process of the motor driving the moving part to move the blank, the transmission structure of the driving wheel and the driven wheel of this utility model synchronously triggers the opening and closing action of the shearing part, forming a linkage control of blank moving and tail cutting operation. When the moving part completes the blank transfer and resets, the shearing part automatically cuts the tail of the blank in place. There is no need for additional independent control of the shearing process, realizing seamless and automated action connection, which shortens the process interval time and improves the overall production efficiency.

The mechanical transmission structure of actuating component 25 and shearing component 35 is stable and reliable, adaptable to high-speed assembly line operation, and reduces human operation error and safety risks. Example 2

[0028] Please see Figure 1-5Based on Embodiment 1, the transmission component 23 includes a rotating plate 231, one side of which is fixedly connected to the motor 22, and the other side of the rotating plate 231 is movably connected to an inclined plate 232. One side of the inclined plate 232 is movably connected to the slide plate 24. The actuating component 25 includes an electric telescopic rod 251, which is disposed through the top of the slide plate 24. A horizontal plate 252 is fixedly connected to the output end of the electric telescopic rod 251, and evenly distributed actuating plates 253 are fixedly connected to the top of the horizontal plate 252. The shearing component 35 includes a connecting frame 351, one side of which is fixedly connected to the table 1. Scissors 352 are movably connected to the inner wall of the connecting frame 351. A limit groove 353 is formed on the surface of the scissors 352, and a sliding connection is made to the inner wall of the limit groove 353. A limiting plate 354 is included, with a vertical rod 355 fixedly connected to its bottom. An adjusting frame 356 is fixedly connected to the bottom of the vertical rod 355. An adjusting rod 357 is slidably connected to the inner wall of the adjusting frame 356, with one end of the adjusting rod 357 fixedly connected to a circular plate 32. A limiting sleeve 4 is fixedly connected to the surface of the vertical plate 31, with a moving groove at its top to accommodate the movement of the vertical rod 355. The limiting sleeve 4 and the vertical rod 355 are slidably connected. Supports 5 are fixedly connected to both sides of the top of the tabletop 1, with fixed frames fixedly connected to both sides of the supports 5. A feed shell 6 is fixedly connected between the fixed frames. Support legs are fixedly connected to the bottom of the tabletop 1, with two stabilizing plates fixedly connected between them. Rubber pads with anti-slip textures are fixedly connected to the bottom of the support legs.

[0029] Specifically: The rotating plate 231 of the transmission component 23 is fixed to the output end of the motor 22, and the other side is movably connected to the slide plate 24 through the inclined plate 232, converting the circular motion of the motor 22 into the linear reciprocating motion of the slide plate 24. The crank-slider transmission structure has a precise motion trajectory, and the stroke of the slide plate 24 can be controlled by adjusting the radius of the rotating plate 231 to adapt to the feeding distance adjustment of different specifications of blanks. The electric telescopic rod 251 of the actuating component 25 drives the horizontal plate 252 to rise and fall, driving the evenly distributed actuating plates 253 to rise or fall. In conjunction with the lateral movement of the slide plate 24, the intermittent actuating conveying of the blanks is realized. The height-adjustable actuating plate 253 is designed to be compatible with blow-molded bottle blanks of different heights, avoiding the problem of material jamming caused by blank stacking. The circular plate 32 of the shearing component 35 rotates with the driven wheel 33, and drives the vertical rod 355 to move up and down through the adjusting rod 357. The vertical rod 355 is limited by the limit. Plate 354 slides within the limiting groove 353 of shears 352, controlling the opening and closing angle of shears 352 to achieve precise shearing of the billet tail. The circular motion is converted into the opening and closing action of shears 352. The shearing frequency is synchronized with the feeding rhythm. The supports 5 on both sides of the table 1 support the unloading shell 6 through the fixed frame, which is used to store the blow-molded bottle billet to be sheared. The billet can be guided into the feeding area by gravity or the actuating component 25. The unloading shell 6 and the actuating component 25 are precisely matched to achieve orderly feeding of the billet, avoiding the inefficient operation of manually placing them one by one. The support legs at the bottom of the table 1 are connected by two stabilizing plates to enhance the vibration resistance of the equipment and ensure that the table 1 is stable and does not shake during the shearing process. The stabilizing plate design significantly improves the overall rigidity of the equipment and ensures the stability of long-term operation. The rubber pads at the bottom of the support legs have anti-slip textures to increase the friction with the ground and prevent the equipment from shifting under the shearing impact force.

[0030] The working principle of this utility model is as follows: The blow-molded bottle preform requiring tail trimming is placed into the feeding shell 6. The actuating component 25 is activated to raise the preform, causing the electric telescopic rod 251 to extend and raise the horizontal plate 252. The horizontal plate 252 then raises the actuating plate 253. The motor 22 is activated, causing the transmission component 23 to rotate. The rotating plate 231 rotates, causing the inclined plate 232 to rotate. The inclined plate 232 causes the sliding plate 24 to slide left and right on the inner wall of the table 1. The sliding plate 24 causes the actuating component 25 to move left and right. The actuating component 25 moves the blow-molded bottle preform requiring tail trimming to one side of the tail trimming mechanism 3. Simultaneously, the motor 22, driving the sliding plate 24, drives the driving wheel 34 to rotate. The driving wheel 34 drives the driven wheel 33 to rotate, and the driven wheel 33 causes the shearing component 35 to open. When the motor 22 drives the actuating component... When 25 is about to reset, the actuating component 25 descends, the electric telescopic rod 251 shortens, causing the horizontal plate 252 to descend, and the horizontal plate 252 causes the actuating plate 253 to descend, so that it does not contact the blow-molded bottle blank. Then the motor 22 drives the actuating component 25 to reset, and the shearing component 35 trims the tail of the blow-molded bottle blank that has been actuated. The motor 22 drives the driving wheel 34 to rotate, the driving wheel 34 drives the driven wheel 33 to rotate, the driven wheel 33 drives the circular plate 32 to rotate, the circular plate 32 drives the adjusting rod 357 to rotate, the adjusting rod 357, together with the adjusting frame 356, drives the vertical rod 355 to move up and down, and the vertical rod 355 drives the limiting plate 354 to move up and down in the limiting groove 353 on the shearing blade, so that the shearing blade opens and closes. The shearing component 35 can trim the tail of the blow-molded bottle blank that needs to be trimmed in sequence.
