[0002] At present, the commonly used can turning mechanisms include POM mold turning mechanism, magnetic can turning mechanism, and bottle clamp turning mechanism, each of which has its own advantages and disadvantages. Among them, the POM mold turning mechanism has high efficiency, but poor versatility. Different can types need to be re-molded, which is suitable for large-scale production of a single can type. The magnetic can turning mechanism has a simple structure, but it can only be applied to iron cans and cannot be used for other can body materials.

[0003] In the related art, the bottle clamping and can turning mechanism adopts a reciprocating can turning method, wherein the bottle clamping cylinder is fixed on the turning shaft.

Then, the turning shaft turns backward 180°, driving the bottle clamping cylinder back to the initial position, waiting for the next can body to enter. However, since the process of the turning shaft turning backward cannot realize the can body turning, half of the entire action cycle is an empty stroke, and there is a problem of low can turning efficiency.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] At present, the commonly used can turning mechanisms include POM mold turning mechanism, magnetic can turning mechanism, and bottle clamp turning mechanism, each of which has its own advantages and disadvantages. Among them, the POM mold turning mechanism has high efficiency, but poor versatility. Different can types need to be re-molded, which is suitable for large-scale production of a single can type. The magnetic can turning mechanism has a simple structure, but it can only be applied to iron cans and cannot be used for other can body materials.

[0035] In the related art, the bottle clamping and can turning mechanism adopts a reciprocating can turning method, wherein the bottle clamping cylinder is fixed on the turning shaft. During use, after the bottle clamping cylinder clamps the bottle body, the cylinder or motor drives the turning shaft to turn forward 180°, and then the bottle clamping cylinder releases the can body, and the can body is taken away by the conveyor belt to realize the can body turning. Then, the turning shaft turns backward 180°, driving the bottle clamping cylinder back to the initial position, waiting for the next can body to enter. However, since the process of the turning shaft turning backward cannot realize the can body turning, half of the entire action cycle is an empty stroke, and there is a problem of low can turning efficiency.

[0036] For this reason, Figure 1 and Figure 2 As shown, a continuous rotary bottle clamping and can turning mechanism proposed by the utility model comprises a frame 100, a turning assembly 200 mounted on the frame 100, and a clamping assembly 300 mounted on the turning assembly 200. Specifically, the turning assembly 200 comprises a turning shaft 220 and a driving motor 210, and the driving motor 210 is connected to and drives the turning shaft 220 to rotate. Further, there are two clamping assemblies 300, which are suitable for clamping bottles and cans 500. The two clamping assemblies 300 are symmetrically mounted on both sides of the turning shaft 220. The two clamping assemblies 300 cooperate with the turning assembly 200 to clamp the bottles and cans 500 located on one side of the turning shaft 220 and turn them to the other side of the turning shaft 220. It should be noted that since the two clamping assemblies 300 are symmetrically arranged on both sides of the flip shaft 220, no matter whether the flip shaft 220 is flipped 180° forward or backward, the two clamping assemblies 300 can always be rotated to both sides of the flip shaft 220 in turn. Therefore, in each rotation stroke of the flip shaft 220, through the cooperation of the two clamping assemblies 300, the bottle 500 located on one side of the flip shaft 220 can be flipped to the other side of the flip shaft 220, thereby realizing continuous flipping operation of the bottle 500 in repeated motion, without empty stroke in the entire action cycle, and doubling the efficiency of turning the cans.

[0037] Refer to Figure 1 and Figure 2In some embodiments of the utility model, the frame 100 is slidably mounted with a lifting plate 110 in the vertical direction, the lifting plate 110 is connected to the frame 100 in a transmission manner in the vertical direction, and the flip assembly 200 is mounted on the lifting plate 110. Therefore, the height of the flip assembly 200 can be adjusted to better cooperate with the bottles 500 transported from both sides of the flip shaft 220, so that the clamping assembly 300 can better clamp the middle of the bottles 500. For example, when the height of the bottles 500 is high, the lifting plate 110 is adjusted upward; when the height of the bottles 500 is small, the lifting plate 110 is adjusted downward. Specifically, a guide structure along the vertical direction is provided between the frame 100 and the lifting plate 110, and optionally, the guide structure includes a linear bearing and an optical axis, which are respectively mounted on the lifting plate 110 and the frame 100, and the optical axis is passed through the inner ring of the linear bearing and slidably matched with the inner ring of the linear bearing. In some embodiments, the guide structure includes a slider and a guide rail that slide with each other, for example, the slider and the guide rail are respectively installed on the lifting plate and the frame (not shown in the figure). In some embodiments of the utility model, the lifting plate 110 is adjusted manually, which is convenient to operate. Specifically, the frame 100 is rotatably provided with a screw 121 arranged in the vertical direction, wherein a rotating disk 120 is installed at one end of the screw 121, and the other end is threadedly connected to the lifting plate 110, and the rotating disk 120 is connected and drives the screw 121 to rotate, so as to drive the lifting plate 110 to move along the center line direction of the screw 121. In some embodiments, the lifting plate 110 is adjusted automatically, for example, the end of the screw 121 away from the lifting plate 110 is connected to the motor, and the lifting plate 110 is driven to move up and down by the rotation of the motor. In addition, there are two guide structures, and the two guide structures are arranged on both sides of the screw 121, respectively, so that the guiding effect is better. When a linear bearing and an optical axis are used as the guide structure, the two guide structures arranged on both sides of the screw rod 121 can prevent the lifting plate 110 from rotating during the threaded transmission with the screw rod 121 .

[0038] In some embodiments, there are two lifting plates 110, which are respectively disposed at both ends of the flip shaft 220, so as to better support the flip shaft 220. In addition, there are two rotating disks 120 and two screw rods 121, and the rotating disks 120, the screw rods 121 and the lifting plates 110 correspond to each other. Furthermore, the two rotating disks 120 respectively adjust the two ends of the flip shaft 220, so as to better adjust the flip shaft 220 to a horizontal position.

[0039] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the clamping assembly 300 includes a clamping cylinder 310 and a clamping block 320, and the clamping cylinder 310 is connected to and drives the clamping block 320 to move, so as to drive the clamping block 320 to clamp the bottle 500. The cylinder 310 is clamped pneumatically, and the size of the clamping force can be conveniently adjusted by the size of the intake air pressure or the speed regulating valve installed on the cylinder, so as to adapt to the clamping of bottles 500 of different sizes and different materials. For example, a fixed block is fixedly installed on the flip shaft, and the fixed block and the clamping block are arranged opposite to each other. When the bottle is located between the fixed block and the clamping block, the clamping cylinder is connected and drives the clamping block to move toward one side of the fixed block, and the fixed block and the clamping block respectively press against the opposite side walls of the clamped bottle (not shown in the figure). In some embodiments, there are two pressing cylinders 310 and two pressing blocks 320, the two pressing cylinders 310 are arranged opposite to each other, the two pressing blocks 320 are arranged opposite to each other, the two pressing cylinders 310 are connected and drive the two pressing blocks 320 to move toward or away from each other to clamp or release the bottle 500, and the use effect is better. On the one hand, after the two pressing blocks 320 press the bottle 500, the bottle 500 can be placed in the middle position of the two pressing cylinders 310. On the other hand, after the bottle 500 is released, the two pressing blocks 320 keep a certain distance from the bottle 500, which is convenient for picking up, conveying, etc. of the bottle 500 in the next process. Further, the flip shaft 220 is equipped with two mounting plates 221, and the two mounting plates 221 are arranged at intervals along the center line direction of the flip shaft 220. The two pressing cylinders 310 located at one end of the flip shaft 220 are installed on one of the mounting plates 221, and the two pressing cylinders 310 located at the other end of the flip shaft 220 are installed on the other mounting plate 221 opposite to each other. Thus, the positions of the two clamping assemblies 300 can be relatively accurately and symmetrically arranged on both sides of the flip shaft 220, and the two clamping assemblies 300 take turns to grab and flip the bottles 500 from one side of the flip shaft 220 to the other side of the flip shaft 220, and the position consistency is good. In some embodiments, a pin shaft positioning structure is provided between the mounting plate 221 and the flip shaft 220 to further improve the accuracy of the mounting position of the mounting plate 221, and thus ensure the position accuracy between the two clamping assemblies 300. For example, the mounting plate 221 is provided with a first positioning hole, the flip shaft 220 is provided with a second positioning hole, and the positioning pin is inserted through the first positioning hole and the second positioning hole. Furthermore, there are multiple second positioning holes, and the multiple second positioning holes are arranged at intervals along the center line direction of the flip axis 220, so that the mounting plate 221 has multiple installation positions between the positioning pins located in the second positioning holes and the flip axis 220, so that the interval between the two mounting plates 221 can be easily adjusted, which is suitable for clamping bottles 500 with different outer diameters.In some embodiments, one end of the flip shaft 220 is connected to the driving shaft of the driving motor 210, and the flip shaft 220 is driven by the motor to rotate. The rotation accuracy of the flip shaft 220 is relatively high. Furthermore, a reducer is provided between the driving motor 210 and the flip shaft 220, which can reduce speed and increase torque, thereby improving the stability of the rotation of the flip shaft 220. See again. Figure 2 In some embodiments, a sensor 400 is provided on the outer side of the flip shaft 220, and the flip shaft 220 rotates relative to the sensor 400. The sensor 400 is used to detect the flip position of the flip shaft 220, so as to avoid the deviation of the clamping position of the can 300 caused by the accumulated error of the driving motor 210 after long-term use. Specifically, a detection plate 223 is relatively fixed to the flip shaft 220. When the flip shaft 220 rotates, the detection plate 223 rotates together with the flip shaft 220. When the flip shaft 220 rotates to a horizontal preset position, the sensor 400 detects the detection plate 223 and sends an electrical signal, and then sends a signal to the clamping assembly 300 to clamp the bottle 500. In addition, in order to avoid the problem of air pipe entanglement caused by the continuous unidirectional rotation of the flip shaft 220, the other end of the flip shaft 220 is connected to the frame 100 through a rotating air joint 222, so that the flipping movement of the flip shaft 220 has greater flexibility, and can be reciprocated and rotated at intervals or maintained in a unidirectional interval rotation. The rotating air joint 222 has four air paths to achieve continuous air supply during the rotation of the compression cylinder 310 .

[0040] In some embodiments, the end surface of the pressing block is a plane, and is in line contact with the bottle (not shown in the figure). Figure 1 and Figure 2 In some embodiments of the present invention, a positioning groove 321 is provided at the end of the pressing block 320, and the positioning groove 321 is used to position the bottle 500, increase the contact area between the bottle 500 and the bottle 500, and have a better pressing effect on the bottle 500. For example, the positioning groove 321 is a V-shaped groove.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
