Description

Technical Field

[0001] This utility model relates to the field of beverage production technology, specifically to a bottle variable frequency speed control conveying device. Background Technology

[0002] In the field of beverage production technology, bottle conveying devices are an indispensable and important component of the production line. They are responsible for efficiently and stably transporting empty or full bottles to various processing stations, such as filling, labeling, and packaging. However, existing bottle conveying devices still have certain shortcomings, such as:

[0003] A bottle positioning and conveying device, as proposed in application number CN202421291233.7, includes a mounting frame, a conveying device, a first baffle, a second baffle, and a spacing adjustment device. The conveying device is mounted on the mounting frame and is suitable for conveying bottles. The first baffle and the second baffle are arranged opposite each other on both sides of the conveying device. The length directions of the first baffle and the second baffle are parallel to each other and extend along the conveying direction of the conveying device. The spacing adjustment device includes a spacing fixing frame and an adjustment part. The spacing fixing frame is located on one side of the conveying device. The first baffle is movably connected to the spacing fixing frame through the adjustment part. The first baffle can move in a direction toward or away from the second baffle, which is suitable for adjusting the distance between the first baffle and the second baffle. In actual use, during the conveying of bottles, the moving bottles will slide and rub against the inner side of the baffle, which will cause frictional obstruction to the movement of the bottles and wear on the surface of the bottles. At the same time, the height of the baffle is not adjustable. When conveying bottles of different heights, the center of gravity of the bottles is different, so a good positioning effect cannot be achieved. Utility Model Content

[0004] The purpose of this utility model is to provide a bottle variable frequency speed control conveying device to solve the problems mentioned in the background art, such as friction affecting the conveying and causing wear, and the inconvenience of adapting and adjusting the positioning structure according to the bottle height.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle body frequency conversion speed regulation conveying device, including a conveyor belt, with protective boxes attached to both sides of the conveyor belt;

[0006] The speed change transmission mechanism, installed inside the protective box, is used to drive and regulate the speed of the conveyor belt;

[0007] Support frames are symmetrically installed on the outer sides of both ends of the protective box;

[0008] Adjustable limiting mechanisms are symmetrically arranged at the top of the conveyor belt for positioning the bottles during transport.

[0009] A fixing plate is fixedly installed at the bottom of the adjusting limit mechanism on both sides, and a bottom plate is fixedly installed on the bottom surface of the middle part of the protective box;

[0010] The height adjustment mechanism is connected to the bottom surface of the base plate and works with the fixed plate to adjust the height of the limit mechanism.

[0011] As a preferred technical solution of this utility model, the speed transmission mechanism includes transmission rollers evenly distributed between the two protective boxes on both sides. A rotating rod is fixedly connected to the inner ring of the transmission roller. The two ends of the rotating rod are rotatably connected to the protective box. Pulleys are fixedly sleeved on both ends of the rotating rod. Adjacent sets of rotating rods are connected by a pulley and a transmission belt. A driven gear is fixedly installed on the left end of the front rotating rod. A driving gear is meshed with the bottom of the driven gear. A support base is fixedly installed on the front support frame. A variable frequency motor is installed on the top of the support base. The end of the variable frequency motor is fixedly connected to the driving gear.

[0012] The above technical solution facilitates precise control of the rotation frequency of the drive gear through the speed adjustment function of the variable frequency motor. The transmission combination of the driven gear, pulley, and transmission belt enables the speed adjustment of the conveyor belt. This transmission structure utilizes the dual stability of gear meshing and belt transmission to maintain the stability of the conveying speed during speed adjustment, avoiding bottle tipping or conveying jams caused by speed fluctuations. At the same time, it adapts to the differentiated conveying speed requirements of different workstations such as filling and labeling.

[0013] As a preferred technical solution of this utility model, the adjusting and limiting mechanism includes movable plates symmetrically distributed on the top of the conveyor belt, connecting plates symmetrically installed on the inner side of the movable plates, and rolling rods rotatably installed between the connecting plates at equal intervals.

[0014] As a preferred technical solution of this utility model, the adjusting and limiting mechanism further includes a connecting shaft installed in the middle of the outer side of the two movable plates. The inner ring of the connecting shaft is connected to a first adjusting rod, and the outer ring of the first adjusting rod is threaded with a positioning plate. The bottom end of the positioning plate is fixedly connected to the protective box. Limiting rods are fixedly installed at both ends of the outer side of the two movable plates. The outer ring of the limiting rod is fitted with a limiting plate, and the bottom end of the limiting plate is fixedly connected to the protective box.

[0015] As a preferred embodiment of this utility model, the limiting rod and the limiting plate are slidably connected through each other, and the bottom of the positioning plate and the limiting plate are fixedly connected to the fixing plate.

[0016] By adopting the above technical solution, the rolling contact between the rolling rod and the bottle body can replace the sliding friction of the traditional baffle, converting the friction force during bottle conveying into rolling resistance, which greatly reduces the wear on the bottle surface and the conveying resistance. At the same time, rotating the first adjusting rod can drive the movable plate to move laterally along the limiting rod through the threaded transmission. In conjunction with the sliding guide structure of the limiting plate, the positioning distance of bottles with different diameters can be adjusted to ensure that the bottle body remains centered during the conveying process and avoids processing errors caused by deviation.

[0017] As a preferred embodiment of this utility model, the height adjustment mechanism includes a positioning shaft installed in the middle of the bottom surface of the base plate. The inner ring of the positioning shaft is connected to a second adjusting screw. A rotating wheel is fixedly installed at the bottom end of the second adjusting screw. A linkage plate is sleeved on the outer ring of the second adjusting screw. Lifting plates are symmetrically connected to both ends of the linkage plate. The top of the lifting plate is fixedly connected to a fixed plate. A lifting rod is slidably arranged inside the support frame. The top end of the lifting rod is fixedly connected to the fixed plate.

[0018] As a preferred embodiment of this utility model, the second adjusting screw is threadedly connected to the linkage plate, and the linkage plate is arranged in an "X" shape.

[0019] By adopting the above technical solution, it is convenient to drive the second adjusting screw to rotate by rotating the wheel. Utilizing the lever transmission principle of the "X"-shaped linkage plate, the rotational motion of the screw is converted into the vertical displacement of the lifting plate, thereby synchronously adjusting the height of the two fixed plates. This structure can flexibly adjust the vertical position of the movable plate according to the height of the bottle, so that the contact point between the rolling rod and the bottle is always at the optimal positioning height. It is especially suitable for conveying bottles of different specifications, improving the versatility and positioning reliability of the device.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the bottle body frequency conversion speed regulation conveying device;

[0021] 1. By adjusting the rolling rod design of the limiting mechanism, the sliding friction between the bottle and the limiting structure is transformed into rolling contact, which significantly reduces the wear on the bottle surface and the conveying resistance. At the same time, the positioning distance of bottles with different diameters can be adjusted through the cooperation of the first adjusting rod and the limiting rod, ensuring that the bottle is centered during the conveying process. The height adjustment mechanism uses the transmission structure of the "X"-shaped linkage plate and the second adjusting screw to flexibly adjust the vertical position of the movable plate according to the height of the bottle, so that the contact point between the positioning structure and bottles of different specifications is always at the optimal height, solving the positioning problem that traditional devices cannot adapt to the center of gravity of different bottles.

[0022] 2. The variable speed transmission mechanism uses a combination design of variable frequency motor, gear and belt drive to realize variable speed adjustment of the conveyor belt. It can not only accurately match the different speed requirements of different work stations such as filling and labeling, but also avoid bottle tipping caused by speed fluctuations through the dual stability of the transmission system.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 6The present invention provides a variable frequency speed control conveying device for bottles, comprising a conveyor belt 1, protective boxes 2 attached to both sides of the conveyor belt 1, and a variable speed transmission mechanism installed inside the protective boxes 2 for transmitting and regulating the speed of the conveyor belt 1. The variable speed transmission mechanism includes transmission rollers 3 evenly distributed between the two protective boxes 2, a rotating rod 5 fixedly connected to the inner ring of the transmission roller 3, the two ends of the rotating rod 5 being rotatably connected to the protective box 2 through the rollers 3, pulleys 4 fixedly sleeved at both ends of the rotating rod 5, and adjacent sets of rotating rods 5 being connected by the pulleys 4 and the transmission belt 6. A driven gear 7 is fixedly installed at the left end of the front rotating rod 5, and a driving gear 8 is meshed with the bottom of the driven gear 7. A support base 10 is fixedly installed on the front support frame 11, a variable frequency motor 9 is installed on the top of the support base 10, and the end of the variable frequency motor 9 is fixedly connected to the driving gear 8. Support frames 11 are symmetrically installed on the outer sides of both ends of the protective box 2.

[0032] In the above structure, when the variable frequency motor 9 is powered on, its output shaft drives the drive gear 8 to start rotating. The drive gear 8 transmits power to the front rotating rod 5 through the meshing driven gear 7. Then, the front rotating rod 5 drives the other rotating rods 5 to rotate through the meshing structure formed by the pulley 4 and the transmission belt 6. When the rotating rod 5 rotates, it will drive the transmission roller 3 fixedly installed on its outer ring to rotate. Because the outer surface of the transmission roller 3 is in close contact with the inner side of the conveyor belt 1, the friction force drives the conveyor belt 1 to make linear motion to complete the bottle conveying.

[0033] The variable frequency motor 9 can precisely adjust its speed by changing the input power frequency. When the speed of the variable frequency motor 9 increases, the drive gear 8 rotates faster, and the speed of the driven gear 7 and the front rotating rod 5 increases accordingly. Through the transmission of the pulley 4 and the transmission belt 6, the speed of the subsequent transmission roller 3 increases, and the speed of the conveyor belt 1 increases. Conversely, when the speed of the variable frequency motor 9 decreases, the speed of the conveyor belt 1 decreases. The through-rotation connection between the two ends of the rotating rod 5 and the protective box 2 ensures the stability of the shaft system and adapts to the speed requirements of different work positions such as filling and labeling.

[0034] An adjusting and limiting mechanism is symmetrically arranged on the top of the conveyor belt 1 for positioning the bottle conveyor. The adjusting and limiting mechanism includes movable plates 12 symmetrically distributed on the top of the conveyor belt 1. Connecting plates 13 are symmetrically installed on the inner side of the movable plates 12. Rolling rods 14 are rotatably installed between the connecting plates 13 at equal intervals. The adjusting and limiting mechanism also includes a connecting shaft 15 installed in the middle of the outer side of the two movable plates 12. The inner ring of the connecting shaft 15 is connected to a first adjusting rod 16. The outer ring of the first adjusting rod 16 is threaded with a positioning plate 17. The bottom end of the positioning plate 17 is fixedly connected to the protective box 2. Limiting rods 18 are fixedly installed at both ends of the outer side of the two movable plates 12. The outer ring of the limiting rod 18 is fitted with a limiting plate 19. The limiting rod 18 and the limiting plate 19 are slidably connected through each other. The bottom end of the limiting plate 19 is fixedly connected to the protective box 2.

[0035] The above structure is designed so that when the bottle moves with the conveyor belt 1 between the two movable plates 12, the side of the bottle contacts the rolling rod 14. The rolling rod 14 can rotate around its own axis, which transforms the traditional sliding friction into rolling friction, reducing the wear on the bottle surface and the conveying resistance. The equidistant arrangement of the rolling rods 14 forms a continuous support surface, ensuring that the bottle maintains a centered posture during the conveying process.

[0036] When it is necessary to adjust the spacing of the movable plates 12, rotate the first adjusting rod 16. Since the positioning plate 17 is fixed, the threaded transmission of the first adjusting rod 16 will push the connecting shaft 15 to move the movable plates 12 in the horizontal direction. The limiting rods 18 fixed at both ends of the outer side of the movable plates 12 are fitted with limiting plates 19. The limiting rods 18 and the limiting plates 19 are slidably connected through each other. The bottom end of the limiting plates 19 is also fixed to the protective box 2. In this structure, the limiting plates 19 provide sliding guidance for the limiting rods 18, ensuring that the movable plates 12 remain vertical when moving and avoid tilting, thereby stabilizing the adjustment of the spacing of the two rolling rods 14 and adapting to bottles of different diameters.

[0037] A fixed plate 20 is fixedly installed at the bottom of the two side adjustment limit mechanisms. A base plate 21 is fixedly installed on the bottom surface of the middle part of the protective box 2. The bottom of the positioning plate 17 and the limit plate 19 are fixedly connected to the fixed plate 20. The height adjustment mechanism is connected to the bottom surface of the base plate 21 and works with the fixed plate 20 to adjust the height of the adjustment limit mechanism. The height adjustment mechanism includes a positioning shaft 22 installed in the middle of the bottom surface of the base plate 21. The inner ring of the positioning shaft 22 is connected to a second adjusting screw 23. A rotating wheel 24 is fixedly installed at the bottom end of the second adjusting screw 23. A linkage plate 25 is sleeved on the outer ring of the second adjusting screw 23. The second adjusting screw 23 and the linkage plate 25 are threaded through each other. The linkage plate 25 is set in an "X" shape. Lifting plates 26 are symmetrically connected at both ends of the linkage plate 25. The top of the lifting plate 26 is fixedly connected to the fixed plate 20. A lifting rod 27 is slidably arranged inside the support frame 11. The top of the lifting rod 27 is fixedly connected to the fixed plate 20.

[0038] The above structure is designed so that rotating the wheel 24 of the height adjustment mechanism drives the second adjusting screw 23 to rotate in conjunction with the positioning shaft 22. Since the second adjusting screw 23 is threadedly connected to the linkage plate 25, the rotation of the second adjusting screw 23 is converted into the vertical lifting and lowering of the linkage plate 25. When the linkage plate 25 moves upward, it drives the lifting plates 26 at both ends to rise. When the linkage plate 25 moves downward, it drives the lifting plates 26 to fall. Since the top of the lifting plate 26 is fixed to the fixed plate 20, it pushes the overall lifting and lowering of the adjustment and limiting mechanism, so that the height of the rolling rod 14 matches the center of gravity of the bottle. The sliding connection between the lifting rod 27 and the support frame 11 can effectively support and limit the height adjustment of the fixed plate 20 and the adjustment and limiting mechanism.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
