Description

Technical Field

[0001] This utility model relates to the field of bottle clamping and lifting machine technology, and in particular to a bottle clamping and lifting machine for inverting bottles. Background Technology

[0002] In production lines of beverage, food, and daily chemical industries, container conveying and lifting are crucial steps. Traditional bottle clamping machines mostly employ rigid clamping structures, such as the technical solution disclosed in patent CN221252838U. This solution uses a lead screw to drive two conveyor beams to move in opposite directions, adjusting the spacing between the clamping plates. A chain drives a sliding block to slide on a slide rail, and the movement of the sliding block causes the connecting belt and the clamping plates on it to rotate, facilitating the clamping and conveying of the bottle. However, this technology still has the following technical drawbacks: 1. Limitations in adaptability: Although this patent achieves spacing adjustment through screw drive, it relies on motor drive and requires multiple motors, which increases equipment cost. Furthermore, the independent control of multiple motors poses a risk of inconsistent adjustment accuracy, which can easily cause deviation during container transport. 2. High risk of container damage: The clamping plates are not flexible and are usually made of metal or hard plastic that makes hard contact with the container surface. They are prone to friction and scratches during transportation, which has a significant impact on high-end containers with surface coating or labeling.

[0003] Therefore, there is an urgent need for a bottle clamping machine technology that can quickly and synchronously adjust the spacing, reduce container damage, and simplify the structure. Utility Model Content

[0004] Therefore, it is necessary to provide a lifting and inverting bottle clamping machine to address the problems of asynchronous spacing adjustment, easy damage to containers, and complex structure of existing bottle clamping machines, so as to achieve efficient, stable, and low-damage conveying of containers.

[0005] To achieve the above objectives, this utility model provides a lifting and inverting bottle clamping machine, including a frame, two flexible clamping and conveying devices, and multiple spacing adjustment devices. The spacing adjustment devices are mounted on the frame and have two movable ends capable of moving towards or away from each other. The two flexible clamping and conveying devices are respectively mounted on the two movable ends. Adjacent spacing adjustment devices are connected by a transmission mechanism to synchronously adjust the spacing between the two flexible clamping and conveying devices.

[0006] Preferably, the flexible clamping and conveying device includes a chain guide rail, a driving sprocket, a driven sprocket, a transmission wheel, and a flexible chain. The chain guide rail is fixedly installed on the frame. The driving sprocket, driven sprocket, and transmission wheel are all rotatably connected to the chain guide rail.

The flexible chain is composed of multiple bottle-clamping chain plates with flexible clamps spliced ​​together. The bottle-clamping chain plates are slidably connected to the chain guide rail and arranged in a closed loop along the path of the chain guide rail.

[0007] Preferably, the chain guide rail includes an upper straight segment, an upper arc segment, a vertical segment, a lower arc segment, and a lower straight segment connected in sequence.

Both the upper arc segment and the lower arc segment are provided with matching transmission wheels.

[0008] Preferably, the upper straight segment is located on the side of the vertical segment facing the lower straight segment, and the chain guide has a C-shaped structure.

[0009] Preferably, the upper straight segment is located on the side of the vertical segment opposite to the lower straight segment, and the chain guide has an S-shaped structure.

[0010] Preferably, the flexible clamping and conveying device further includes a drive motor and a reducer. The reducer is a worm gear reducer. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive sprocket.

[0013] Preferably, the vertical section is connected to at least two spacing adjustment devices, and the drive right-angle commutator connected to the fixed seat of the two spacing adjustment devices is connected to the drive right-angle commutator through a second drive shaft.

[0014] Preferably, a hand crank is installed at the input end of the drive right-angle commutator of one of the transmission mechanisms.

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Please see Figures 1 to 3 This application provides a lifting and inverting bottle clamping machine, including a frame 1, two flexible clamping and conveying devices 2 and multiple spacing adjustment devices 3. The frame 1 serves as the supporting foundation for the entire equipment and provides installation positions for other components.

[0019] The spacing adjustment device 3 is installed on the frame 1. The spacing adjustment device 3 has two moving ends that can move towards or away from each other. Two flexible clamping conveying devices 2 are respectively installed on the two moving ends. Each spacing adjustment device 3 is connected by a transmission mechanism 4 to synchronously adjust the spacing between the two flexible clamping conveying devices 2.

[0020] The flexible clamping and conveying device 2 includes a chain guide rail 21, a drive sprocket 22, a driven sprocket 23, a transmission wheel 24, and a flexible chain 25. The chain guide rail 21 is fixedly installed on the frame 1. The drive sprocket 22, the driven sprocket 23, and the transmission wheel 24 are all rotatably connected to the chain guide rail 21. The flexible chain 25 is drivenly connected to the drive sprocket 22, the driven sprocket 23, and the transmission wheel 24. The flexible chain 25 is composed of multiple bottle clamping chain plates 251 with flexible clamping plates 2511 spliced ​​together. The bottle clamping chain plates 251 are slidably connected to the chain guide rail 21 and arranged in a closed loop along the path of the chain guide rail 21.

[0021] For example, the bottle clamping chain plate 251 is selected from the bottle clamping chain plate and the bottle clamping chain plate disclosed in CN222794377U. The clamping plate is made of polyurethane elastomer material with a Shore hardness of 50-70A and a surface roughness Ra≤0.8μm. It can adapt to the shape of the container during clamping and can flexibly contact the bottle or can being transported.

[0022] Specifically, the chain guide 21 includes an upper straight section 211, an upper arc section 212, a vertical section 213, a lower arc section 214, and a lower straight section 215 connected in sequence. The upper straight section 211 and the lower straight section 215 are arranged parallel to each other, and the upper straight section 211 and the vertical section 213 are arranged perpendicular to each other. The upper arc section 212 and the lower arc section 214 are each provided with a matching drive wheel 24.

[0023] In this embodiment, the upper straight segment 211 is located on the side of the vertical segment 213 facing the lower straight segment 215, and the chain guide 21 has a C-shaped structure. In other embodiments, the upper straight segment 211 can also be located on the side of the vertical segment 213 away from the lower straight segment 215, in which case the chain guide 21 has an S-shaped structure.

[0024] The spacing adjustment device 3 includes a fixed base 31, a linear guide rail 32, a double-rotating lead screw 33, and a slide block 34. The fixed base 31 is fixedly connected to the frame 1, the linear guide rail 32 is fixedly connected to the fixed base 31, the double-rotating lead screw 33 is rotatably connected to the fixed base 31, and the slide block 34 is slidably connected to the linear guide rail 32 and threadedly connected to the double-rotating lead screw 33. The slide block 34 is the moving end of the spacing adjustment device 3. The double-rotating lead screw 33 has two externally threaded sections rotating in opposite directions, and the two slide blocks 34 are threadedly connected to the two externally threaded sections respectively.

[0025] The upper straight section 211, the vertical section 213, and the lower straight section 215 are all connected to corresponding spacing adjustment devices 3; the transmission mechanism 4 includes a transmission right-angle commutator 41, a drive right-angle commutator 42, and a first transmission shaft 43. The drive right-angle commutator 42 is installed on the fixed base 31. The double-rotating lead screw 33 is connected to the drive right-angle commutator 42. The upper arc section 212 and the lower arc section 214 are each provided with a corresponding transmission right-angle commutator 41. The transmission right-angle commutator 41 is fixedly connected to the frame 1. The transmission right-angle commutator 41 is connected to the drive right-angle commutator 42 adjacent to it through the first transmission shaft 43.

[0026] Furthermore, the vertical section 213 is connected to two spacing adjustment devices 3, and the drive right-angle commutator 42 connected to the fixed base 31 of the two spacing adjustment devices 3 is connected to each other through the second transmission shaft 44.

[0027] To facilitate the operation of the drive pitch adjustment device 3, a hand crank 5 is installed at the input end of the drive right-angle commutator 42 of one of the transmission mechanisms 4. The hand crank 5 allows for convenient manual adjustment. In this embodiment, the hand crank 5 is installed on the input end of the drive right-angle commutator 42 at the lowest end of the frame 1. Due to its low height, it is easy for the operator to access and operate.

[0028] When it is necessary to adjust the distance between the two flexible clamping and conveying devices 2, the hand crank 5 is turned. The hand crank 5 drives the right-angle commutator 42 to rotate, and then transmits the power to the right-angle commutator 41 through the first transmission shaft 43. The right-angle commutator 41 then distributes the power to the double-rotating lead screw 33 of each distance adjustment device 3.

[0029] Since the double-rotating lead screw 33 is threadedly connected to the slide block 34, and the slide block 34 is slidably connected to the linear guide rail 32, the rotation of the double-rotating lead screw 33 will drive the two slide blocks 34 to move towards or away from each other, thereby realizing the synchronous adjustment of the distance between the two flexible clamping conveyor devices 2 to meet the diverse needs of the production line. During container transport, the drive motor 26 starts, and its output power is reduced and increased in torque by the reducer 27 before being transmitted to the drive sprocket 22. The drive sprocket 22 drives the flexible chain 25 to move within the chain guide rail 21.

[0030] The flexible clamp 2511 can adapt to the shape of the container, making flexible contact with the container surface, clamping the container and conveying it along the path of the chain guide 21. Because the chain guide 21 has a C-shaped structure, the container will rotate 180 degrees and become inverted when it is conveyed from the lower straight section 215 to the upper straight section 211.

[0031] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
