Description
Technical Field
[0001] This utility model relates to the field of bottle preform conveying equipment, and in particular to a bottle preform transmission turntable mechanism. Background Technology
[0002] Plastic bottle packaging is widely used in the food, beverage, pharmaceutical, and daily chemical industries. To meet the increasing demand for plastic bottles, plastic bottle processing lines have been automated. After production, preforms are prone to defects such as black spots, off-center bottoms, scratches, bubbles, and broken bottle necks. Therefore, their appearance needs to be inspected to prevent substandard preforms from entering subsequent processing steps or the market.
[0003] When inspecting the appearance of bottle preforms, they are usually placed on a transmission turntable. The appearance of the preforms is photographed and inspected as they rotate. Existing transmission turntable devices are generally equipped with two sets, and each turntable has a bottle-moving component. The bottle-moving component moves the preforms from one turntable to another for inspection. However, since the preforms are made of plastic and have a low weight, moving the preforms by the bottle-moving component can easily lead to misalignment and jamming during the transfer process, resulting in poor stability and affecting the normal inspection of the preforms. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a preform transmission turntable mechanism that can make the preform move smoothly during the inspection process.
[0005] This utility model provides a preform transmission turntable mechanism, comprising:
[0006] The first turntable has multiple slots evenly distributed around its circumference for receiving bottle preforms.
[0007] The second turntable is located on one side of the first turntable, and it has a plurality of second slots evenly distributed around its circumference for pulling the preform out of the first slot.
[0008] A first guiding component is disposed on one side of the first turntable, with one end extending to the edge of the first turntable, for guiding the preform to be tested into the first slot.
[0009] The second guide component is S-shaped and located at the outer edge of the first turntable and the second turntable, and is used to guide the preform from the first turntable to the second turntable;
[0010] A drive assembly, connected to the first turntable and the second turntable, is used to drive the first turntable and the second turntable to rotate in opposite directions about their axes.
[0011] Furthermore, the second guide assembly includes a first arc-shaped plate surrounding the outside of the first turntable and a second arc-shaped plate surrounding the outside of the second turntable. The first arc-shaped plate and the second arc-shaped plate are arranged opposite to each other. A first transition plate is fixedly connected to one end of the first arc-shaped plate near the second arc-shaped plate, and a second transition plate is fixedly connected to one end of the second arc-shaped plate near the first arc-shaped plate. Both the first transition plate and the second transition plate are arranged above the intersection of the first turntable and the second turntable, so that the second guide assembly is arranged in an S-shape along the first turntable and the second turntable.
[0012] Furthermore, guide channels for preforms to pass through are formed between the first arc-shaped plate and the first transition plate and the first turntable, between the second arc-shaped plate and the second transition plate and the second turntable, and between the first transition plate and the second transition plate, so that the preforms move along an S-shaped trajectory.
[0013] Furthermore, the side of the first transition plate near the first turntable and the side of the second transition plate near the second turntable are both recessed inward to form concave arc surfaces.
[0014] Furthermore, the first guiding component includes a fixed frame disposed on one side of the first turntable, and a guide plate fixedly disposed on the fixed frame.

[0016] Furthermore, protective plates are symmetrically arranged above the feed chute.
[0017] Furthermore, the drive assembly includes a first rotating shaft coaxially fixedly connected to the first turntable, a second rotating shaft coaxially fixedly connected to the second turntable, and a third rotating shaft rotatably connected to the mounting base. A first transmission wheel is fixedly sleeved on the outer wall of the first rotating shaft, a first gear is fixedly sleeved on the outer wall of the second rotating shaft, and a second transmission wheel and a second gear are fixedly sleeved on the outer wall of the third rotating shaft. The first transmission wheel and the second transmission wheel are connected by a transmission belt, and the first gear and the second gear are meshed together. One end of the first rotating shaft is connected to a motor that drives its rotation.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] The first turntable of this invention has a first slot evenly distributed around its circumference to hold the preform, and the second turntable has a second slot evenly distributed around its circumference. The driving assembly drives the first and second turntables to rotate in opposite directions.

[0036] The second turntable 2 is located on one side of the first turntable 1. The second turntable 2 has a plurality of second slots 21 evenly distributed around its circumference for pulling the preform out of the first slot 11.
[0037] The first guide component 3 is disposed on one side of the first turntable 1, with one end extending to the edge of the first turntable 1, and is used to guide the preform to be tested into the first slot 11; specifically, the first guide component 3 is connected to the preform feeding mechanism, and the preform flows from the preform feeding mechanism into the first guide component 3 and is guided into the first slot 11 by the first guide component 3.
[0038] The second guide component 4 is S-shaped and located at the outer edge of the first turntable 1 and the second turntable 2, and is used to guide the preform from the first turntable 1 to the second turntable 2.
[0039] The drive assembly 5 is connected to the first turntable 1 and the second turntable 2 and is used to drive the first turntable 1 and the second turntable 2 to rotate in opposite directions around their axes.
[0040] In this embodiment, the first turntable 1 and the second turntable 2 are located on the same horizontal plane and are arranged adjacent to each other. The first slot 11 and the second slot 21 are both groove structures with arcuate shapes. The driving component 5 can drive the first turntable 1 and the second turntable 2 to rotate in opposite directions. During the rotation of the first turntable 1 and the second turntable 2, the preform feeding mechanism transports the preform to be tested to the first guide component 3. Guided by the first guide component 3, the preform smoothly flows from the first guide component 3 into the first slot 11 of the first turntable 1. Then, under the guidance of the second guide component 4, the second turntable 2 removes the preform from the first turntable 1 from the first slot 11 and locks it in the second slot 21. During the rotation of the first turntable 1 and the second turntable 2, the appearance of the preform is inspected by the detection device. This application improves the stability of the preform from feeding to the first turntable 1 and from the first turntable 1 to the second turntable 2 by using the first guide component 3 and the second guide component 4, avoiding jamming and improving the subsequent preform detection effect.
[0041] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the second guide assembly 4 includes a first arc-shaped plate 41 surrounding the outside of the first turntable 1 and a second arc-shaped plate 42 surrounding the outside of the second turntable 2. The first arc-shaped plate 41 and the second arc-shaped plate 42 are arranged opposite to each other. A first transition plate 43 is fixedly connected to one end of the first arc-shaped plate 41 near the second arc-shaped plate 42, and a second transition plate 44 is fixedly connected to one end of the second arc-shaped plate 42 near the first arc-shaped plate 41. The first transition plate 41 and the second transition plate 42 are both arranged above the intersection of the first turntable 1 and the second turntable 2, so that the second guide assembly 4 is arranged in an S-shape along the first turntable 1 and the second turntable 2.
[0042] Preferred, such as Figure 1 and Figure 3 As shown, guide channels are formed between the first arc-shaped plate 41 and the first transition plate 43 and the first turntable 1, between the second arc-shaped plate 42 and the second transition plate 44 and the second turntable 2, and between the first transition plate 43 and the second transition plate 44, for the preform to pass through, so that the preform moves along an S-shaped trajectory. Specifically, the guide channels are S-shaped.
[0043] In this embodiment, a discharge guide 6 is also provided on one side of the second turntable 2. The first arc plate 41 is connected to the first guide component 3, and the second arc plate 42 is connected to the discharge guide 6. The preform to be tested is stuck in the first slot 11 by the first guide component 3. Under the guidance of the first arc plate 41, it rotates stably in the guide channel. Under the guidance of the first transition plate 43 and the second transition plate 44, it moves to the second slot 21 of the second turntable 2, and then flows into the discharge guide 6 under the guidance of the second arc plate 44, and flows out from the discharge guide 6.
[0044] Preferred, such as Figure 1 and Figure 3 As shown, the side of the first transition plate 43 near the first turntable 1 and the side of the second transition plate 44 near the second turntable 2 are both concave inward to form concave arc surfaces. Specifically, the curvature of the concave arc surfaces can better guide the preform from the first turntable 1 to the second turntable 2, avoiding jamming when the preform moves from the first turntable 1 to the second turntable 2.
[0045] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first guiding component 3 includes a fixed frame 31 disposed on one side of the first turntable 1, and a guide plate 32 fixedly disposed on the fixed frame 31. The guide plate 32 includes an inclined portion 321 and a horizontal portion 322. The inclined portion 321 is inclined downward along the direction close to the first turntable 1.

A first transmission wheel 54 is fixedly sleeved on the outer wall of the first rotating shaft 51, a first gear 55 is fixedly sleeved on the outer wall of the second rotating shaft 52, and a second transmission wheel 56 and a second gear 57 are fixedly sleeved on the outer wall of the third rotating shaft 53. The first transmission wheel 54 and the second transmission wheel 56 are connected by a transmission belt 58, and the first gear 55 and the second gear 57 are meshed together. One end of the first rotating shaft 51 is connected to a motor 59 that drives its rotation. Specifically, the motor 59 is connected to a reducer, and the reducer is connected to the first rotating shaft 51.
[0050] In this embodiment, the starter motor 59 can drive the first rotating shaft 51 and the first transmission wheel 5 to rotate. Under the transmission of the second transmission wheel 56 and the transmission belt 58, the third rotating shaft 53 rotates in the same direction as the first rotating shaft 51. The rotation of the third rotating shaft 53 drives the second gear 57 to rotate. The rotation of the second gear 57 drives the first gear 55 meshing with it to rotate in the opposite direction to its rotation, thereby causing the first turntable 1 and the second turntable 2 to rotate in opposite directions.
[0051] Working principle:
[0052] The first turntable 1 has a first slot 11 evenly distributed around its circumference to hold the preform, and the second turntable 2 has a second slot 21 evenly distributed around its circumference. The driving component 5 can drive the first turntable 1 and the second turntable 2 to rotate in opposite directions. During the rotation of the first turntable 1 and the second turntable 2, the preform to be tested is guided by the first guiding component 3 and flows smoothly from the first guiding component 3 into the first slot 11 of the first turntable 1. Then, under the guidance of the second guiding component 4, the second turntable 2 removes the preform from the first turntable 1 from the first slot 11 and holds it in the second slot 21. During the rotation of the first turntable 1 and the second turntable 2, the appearance of the preform is inspected by the detection device. This application improves the stability of the preform from feeding to the first turntable 1 and from the first turntable 1 to the second turntable 2 by using the first guiding component 3 and the second guiding component 4, avoiding jamming and improving the subsequent preform detection effect.
