Description

Technical Field

[0001] This invention relates to the field of bottle unscrambler equipment technology, specifically a pre-screening device and method for bottle unscrambling. Background Technology

[0002] When unloading bottles, if smaller bottles are mixed in with a large number of bottles, the bottle unscrambler cannot separate the smaller bottles. This results in bottles of different sizes being arranged together via a turntable mechanism. If the size deviation is small, it will cause inconsistent product sizes after filling and capping, requiring manual sorting. If the size deviation is large, it will be impossible to effectively limit the bottles, leading to filling failure and affecting the filling production line. Based on this, patent publication number CN217262640U discloses a sorting mechanism. This product uses a rotating turntable to move the bottles, and the return force of a spring... Smaller bottles are pushed out from between guide plate one and guide plate two to the receiving table. If the bottle is of normal size, it can pass through normally, thus pre-screening smaller bottles. However, the above screening method, when using the rebound force for screening, also generates a pushing force on the end of the qualified bottle. Since the bottle itself is a long strip structure, it is easy to cause the bottle to be polarized when force is applied to one end. This can easily cause qualified bottles to get stuck at the discharge position. Based on this, a pre-screening device and method for bottle handling is provided to eliminate the drawbacks of the existing device. Summary of the Invention

[0003] The purpose of this invention is to provide a pre-screening device and method for bottle handling to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A pre-screening device for bottle handling includes a surrounding plate and a rotating chassis fitted at its lower end. The outer side of the surrounding plate is connected and fixed to a base via multiple positioning posts. A rotary motor for driving the rotation of the rotating chassis is connected to the middle of its lower end, and the lower end of the rotary motor is mounted on the base. An inner ring plate for guiding bottle conveying is provided on the inner side of the surrounding plate. A guide plate for guiding the bottles is provided at the feed end of the inner ring plate. A transmission channel for guiding the screening of bottles is provided at the end of the inner ring plate. The transmission channel is connected and fixed to the surrounding plate. An outlet for collecting qualified bottles is provided at the end of the transmission channel. A small bottle outlet for discharging small bottles is provided on the side of the transmission channel. A collection box for collecting small bottles can be provided below the small bottle outlet. A discharge guide for pushing unqualified small bottles to one side is installed on the transmission channel upstream of the small bottle outlet.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0007] In one alternative embodiment: the discharge guide includes a vertically arranged deflector plate inside the transmission channel. When it encounters a small bottle, which is the initial state of the deflector plate, the deflector plate is used to push the bottle towards the bottle outlet side to achieve discharge. The upper end of the deflector plate is fixedly connected to the lower end of the positioning side rod, and the upper end of the positioning side rod is coaxially fixed to the lower end of the rotary column. A rotary groove is provided on the outer side of the rotary column, and a guide crossbar is provided on one side of the rotary groove. The end of the guide crossbar is slidably disposed in the rotary groove. A squeezing roller is provided above the transmission position of the transmission channel upstream of the deflector plate. The distance between the squeezing roller and the rotating base is greater than the diameter of the small bottle. One end of the squeezing roller is rotatably mounted on a support frame. The support frame is connected to a transmission component for driving the guide crossbar to move upward so that the deflector plate deflects away from the bottle outlet side.

[0008] In one alternative embodiment: the transmission component includes a first lifting column disposed on one side of the support frame, the lower end of the first lifting column being slidably disposed with a first guide sleeve on the outside of the transmission channel, the first guide sleeve being connected and fixed to a first reset side block on the outside of the first lifting column by a first spring, a push side rod being disposed on the outside of the first lifting column above the first reset side block, a fulcrum rod being fixed on the transmission channel on one side of the first lifting column, a lever being rotatably disposed at the upper end of the fulcrum rod, one end of the long lever being in contact with the push side rod, one end of the guide crossbar being connected to the upper end of a second lifting column, the lower end of the second lifting column being slidably disposed with a second guide sleeve on the outside of the transmission channel, the second guide sleeve being connected to a second reset side block on the outside of the second lifting column by a second spring, a guide sleeve being disposed on the outside of the second lifting column and slidably disposed with the lever, the end of the guide sleeve being rotatably connected to the side of the second lifting column by a rotating shaft.

[0009] In one alternative: the lever has a polished layer on its outer side.

[0010] In one alternative embodiment: the first lifting column is provided with a fine-tuning mechanism for adjusting the pressing position of the pushing side rod. The fine-tuning mechanism includes a horizontal fine-tuning slider slidably disposed on the outside of the first lifting column. A fine-tuning transmission block is provided at the lower end of the horizontal fine-tuning slider. The fine-tuning transmission block is slidably disposed on the fine-tuning guide rod. The fine-tuning transmission block is also provided with an adjusting screw hole. A fine-tuning screw is fitted in the adjusting screw hole. One end of the fine-tuning screw is rotatably connected to a fixed block on the first lifting column. The other end of the fine-tuning screw is rotatably connected to a fine-tuning fixed block on the surface of the first lifting column. The end of the fine-tuning screw is provided with a fine-tuning knob that is easy to turn by hand. The two ends of the fine-tuning guide rod are respectively fixedly connected to the fine-tuning fixed block and the fixed block.

[0011] In one alternative: the surface of the first lifting column is provided with a scale bar that cooperates with the sliding stroke of the fine-tuning transmission block.

[0012] In one alternative: two guide ramps are provided on the inner side of the transmission channel. The guide ramps are located upstream of the extrusion roller. Each guide ramp is connected to the transmission channel through a fixed shaft. The bottle is guided by the two guide ramps so that the bottle is in the middle position of the extrusion roller.

[0013] In one alternative: the upper middle position of the rotating chassis 21 is a conical structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This application addresses the shortcomings of existing screening equipment by eliminating the deficiencies of the outward push of the elastic plate. Instead, it uses a material guide plate to guide unqualified small bottles outward, while qualified bottles can continue to be conveyed along the conveying path, thereby ensuring the uniformity of bottle specifications.

[0016] 2. The deflection of the feeding plate can also be adjusted to accommodate different bottle diameters, making the product adaptable to different bottle sizes and increasing its adaptability. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-7 As shown, a pre-screening device for bottles includes a surrounding plate 11 and a rotating base 21 fitted at its lower port. The outer side of the surrounding plate 11 is connected and fixed to a base 16 via multiple positioning posts 20. A rotary motor 22 for driving the rotating base 21 is connected to the middle of its lower end. The lower end of the rotary motor 22 is mounted on the base 16. An inner ring plate 12 for guiding bottle conveying is provided on the inner side of the surrounding plate 11. A guide plate 13 for guiding the bottles is provided at the feed end of the inner ring plate 12. A transmission channel 19 for guiding the screening of bottles is provided at the end of the inner ring plate 12. The transmission channel 19 is connected and fixed to the surrounding plate 11. An outlet for collecting qualified bottles is provided at the end of the transmission channel 19. A small bottle outlet 18 for discharging small bottles is provided on the side of the transmission channel 19. A collection box for collecting small bottles can be provided below the small bottle outlet 18. A discharge guide for pushing unqualified small bottles to one side is installed on the transmission channel 19 upstream of the small bottle outlet 18.

[0027] The discharge guide includes a vertically arranged deflector plate 17 inside the transmission channel 19. When encountering a small bottle, which is the initial state of the deflector plate 17, the deflector plate 17 is used to push the bottle towards the small bottle outlet 18 to achieve discharge. The upper end of the deflector plate 17 is fixedly connected to the lower end of the positioning side rod 26. The upper end of the positioning side rod 26 is coaxially fixed to the lower end of the rotary column 24. A rotary groove 25 is formed on the outer side of the rotary column 24. A guide crossbar 23 is provided on one side of the rotary groove 25. The end of the guide crossbar 23 is slidably disposed in the rotary groove 25. An extrusion roller 15 is provided above the transmission position of the transmission channel 19 upstream of the deflector plate 17. The distance between the squeeze roller 15 and the rotating base 21 is greater than the diameter of the small bottle, so the small bottle cannot reach the squeeze roller 15. Only qualified bottles can squeeze the squeeze roller 15. One end of the squeeze roller 15 is rotatably mounted on the support frame 14. The support frame 14 is connected to a transmission component for driving the guide bar 23 to move upward so that the feeding plate 17 deflects away from the small bottle outlet 18. When a suitable bottle is encountered, the bottle exerts a force on the squeeze roller 15. The transmission component drives the guide bar 23 to move upward. The guide bar 23 cooperates with the rotary groove 25, so that the rotary column 24 drives the feeding plate 17 to rotate together. In this way, the qualified bottle moves towards the discharge port at the end of the transmission channel 19.

[0028] The transmission component includes a first lifting column 28 disposed on one side of the support frame 14. The lower end of the first lifting column 28 is slidably disposed with a first guide sleeve 33 on the outside of the transmission channel 19. The first guide sleeve 33 is connected and fixed to a first reset side block 31 on the outside of the first lifting column 28 by a first spring 32. A push side rod 30 is provided on the outside of the first lifting column 28 above the first reset side block 31. A fulcrum rod 34 is fixed on the transmission channel 19 on one side of the first lifting column 28. A lever 29 is rotatably disposed on the upper end of the fulcrum rod 34. One end of the long rod of the lever 29 is in contact with the push side rod 30. One end of the guide crossbar 23 is connected to the upper end of the second lifting column. The lower end of the second lifting column is slidably disposed with a second guide sleeve 36 on the outside of the transmission channel 19. The second guide sleeve 36 is connected to the second reset side block 38 on the outside of the second lifting column by a second spring. The spring 37 is connected, and the outer side of the second lifting column is provided with a guide sleeve 35 that is slidably sleeved with the lever 29. The end of the guide sleeve 35 is rotatably connected to the side of the second lifting column through a rotating shaft. When qualified bottles are conveyed along the transmission channel 19, the diameter of the qualified bottles is large enough to exert a force on the squeezing roller 15. Under the action of the force, the support frame 14 drives the first lifting column 28 to move upward, and pushes the side rod 30 to exert a force on one end of the lever 29. In this way, the other end of the lever 29 will drive the guide sleeve 35 to move downward. The guide sleeve 35 drives the second lifting column to move downward, and the second lifting column drives the guide crossbar 23 to move downward. The end of the guide crossbar 23 cooperates with the rotary groove 25, which in turn drives the rotary column 24 to rotate. The rotary column 24 will drive the mounting frame 27 to deflect away from the small bottle outlet 18. In this way, qualified bottles can be guided to be conveyed out along the discharge port of the transmission channel 19.

[0029] To facilitate the screening of bottles of different diameters, the first lifting column 28 is provided with a fine-tuning mechanism for adjusting the pressing position of the pushing side rod 30. The support position is adjusted by the fine-tuning mechanism, thereby adjusting the deflection amplitude of the feeding plate 17.

[0030] The fine-tuning mechanism includes a horizontal fine-tuning slider 39 slidably disposed on the outside of the first lifting column 28. A fine-tuning transmission block 41 is provided at the lower end of the horizontal fine-tuning slider 39. The fine-tuning transmission block 41 is slidably disposed on the fine-tuning guide rod 42. The fine-tuning transmission block 41 also has an adjusting screw hole, in which a fine-tuning screw 40 is fitted. One end of the fine-tuning screw 40 is rotatably connected to a fixed block on the first lifting column 28, and the other end of the fine-tuning screw 40 is rotatably connected to a fine-tuning fixed block 43 on the surface of the first lifting column 28. The end of the rod 40 is provided with a fine-tuning knob 44 for easy hand rotation. The two ends of the fine-tuning guide rod 42 are fixedly connected to the fine-tuning fixing block 43 and the fixing block, respectively. The fine-tuning knob 44 drives the fine-tuning screw 40 to rotate relative to the fine-tuning fixing block 43. Under the action of the thread, the fine-tuning transmission block 41 slides along the fine-tuning guide rod 42, thereby causing the transverse fine-tuning slider 39 to slide along the surface of the first lifting column 28. In this way, the position of the pushing side rod 30 can be adjusted. If the pushing side rod 30 slides closer to the end of the lever 29, the active lever arm will increase, and vice versa.

[0031] To facilitate adjustment, the surface of the first lifting column 28 is provided with a scale bar that matches the sliding stroke of the fine-tuning transmission block 41, so that it can be adjusted as needed and provides a reference for adjustment;

[0032] Two guide ramps are provided on the inner side of the transmission channel 19. The guide ramps are located upstream of the extrusion roller 15. Each guide ramp is connected to the transmission channel 19 through a fixed shaft. The bottle is guided by the two guide ramps so that the bottle is in the middle position of the extrusion roller 15.

[0033] To make it easier for the bottle to enter the guide plate 13, the upper middle part of the rotating base 21 has a conical structure, which helps the bottle to move closer to the inside of the surrounding plate 11.

[0034] The above embodiment discloses a pre-screening device for bottle handling. In actual use, the bottle is placed inside the enclosure 11. The bottle will enter the channel between the inner ring plate 12 and the enclosure 11 along the guide plate 13. Then the bottle will enter the transmission channel 19. When the small bottle passes the squeezing roller 15, the diameter of the small bottle cannot touch the squeezing roller 15. Under the guidance of the feeding plate 17, the small bottle will be discharged along the small bottle outlet 18. When a qualified bottle is encountered, the bottle exerts a force on the squeezing roller 15. The transmission component drives the guide bar 23 to move upward. The guide bar 23 cooperates with the rotary groove 25, so that the rotary column 24 drives the feeding plate 17 to rotate together. This makes the qualified bottle move towards the discharge port at the end of the transmission channel 19, thereby completing the screening of the bottle.

[0035] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
