[0007] According to one aspect of this utility model, the movable plate is provided with a left-right adjustment knob and a right-up adjustment knob. By rotating the left-right adjustment knob, the left and right connecting members are adjusted, causing the movable plate to move axially with the left and right connecting members, thereby adjusting the lateral distance between the screw bottle-separating mechanism and the conveyor line unit. By rotating the right-up adjustment knob, the left and right connecting members are adjusted, causing the second fixed plate to move axially with the left and right connecting members, thereby adjusting the longitudinal distance between the screw bottle-separating mechanism and the conveyor line unit.

[0008] According to one aspect of the present invention, the driving device includes a screw motor, a motor drive wheel, and a screw drive wheel. The screw motor is mounted on one side of the mounting plate, the motor drive wheel is connected to the screw motor, the screw drive wheel is connected to the screw, and the motor drive wheel and the screw drive wheel are connected to each other by a screw drive belt.

[0009] According to one aspect of the present invention, the screw bottle separating and labeling machine further includes a bottle inverting and rejecting mechanism, which is connected to the conveyor line unit and located between the feeding disc and the screw bottle separating mechanism.

[0010] According to one aspect of the present invention, the sensor includes a missing print detection sensor and a missing label detection sensor. The missing print detection sensor is located above the conveyor line unit and between the labeling host unit and the wheel attachment mechanism, and the missing label detection sensor is located between the wheel attachment mechanism and the cylinder rejection mechanism.

[0011] According to one aspect of the present invention, the screw bottle labeling machine further includes a chassis unit and a human-machine interface unit, wherein the chassis unit is disposed below the conveyor line unit and the human-machine interface unit is located above the chassis unit.

[0012] According to one aspect of the present invention, the screw-operated bottle labeling machine for round bottles further includes an encoder mechanism located at the tail end of the conveyor line unit.

[0013] According to one aspect of the present invention, the feeding disc is connected to the front end of the conveyor unit via an adjustment device, and a horizontally fixed handle and baffle are provided above the feeding disc. The round bottle is fed into the conveyor unit by the cooperation of the handle and the baffle.

[0014] According to one aspect of the present invention, a feeding plate is provided at one end of the feeding disc away from the conveyor unit, the feeding plate being used to receive round bottles that need to enter the feeding disc.

[0015] The advantages of this invention are as follows: The screw-type bottle separating mechanism, including the screw, mounting plate, adjusting device, and driving device, has the screw mounted on one side of the mounting plate and opposite the conveyor unit. The upper end of the adjusting device is mounted on the other side of the mounting plate, and the lower end is mounted on the conveyor unit.

[0027] like Figures 1 to 5As shown, a screw-type bottle labeling machine for round bottles is used to label round bottles. It includes a feeding disc 1, a conveyor unit 3, a bottle-inverting and rejecting mechanism 4, a screw-type bottle-separating mechanism 5, a labeling main unit 6, a sensor, a wheel attachment mechanism 8, and a cylinder rejection mechanism 10. The conveyor unit 3 is a long conveyor belt used to transport round bottles and is sequentially connected to the feeding disc 1, the bottle-inverting and rejecting mechanism 4, the screw-type bottle-separating mechanism 5, the labeling main unit 6, the wheel attachment mechanism 8, and the cylinder rejection mechanism 10.

[0028] The screw bottle-separating mechanism 5 is located on the conveyor line unit 3 and between the feeding disc 1 and the labeling host unit 6. The screw bottle-separating mechanism 5 includes: a screw 501, a mounting plate 509, an adjusting device, and a driving device.

[0029] like Figure 4 , Figure 5 As shown, the mounting plate 509 is a horizontally placed T-shaped plate, including a long plate 514 parallel to the conveyor line unit 3 and a short plate 515 perpendicular to the conveyor line unit 3. A horizontally placed screw 501 is mounted on the side of the long plate 514 closest to the conveyor line unit 3, parallel and opposite to the conveyor line unit 3. The screw 501 can be modified so that the thread spacing on the screw 501 matches the width of the round bottle to be labeled. By rotating the screw 501, the round bottle enters the thread spacing on the screw 501 and is separated. When the screw 501 rotates, the threads also rotate, and the thread spacing moves horizontally to the right at a certain speed. As the threads rotate, the round bottle is pushed to the right within the thread spacing and continues to be conveyed. An L-shaped plate 516 is fixed to the right end of the mounting plate 509. One end of the L-shaped plate 516 is vertically fixed to the right end of the mounting plate 509, making the installation of the screw 501 more stable. The other end of the L-shaped plate 516 is parallel to the conveyor line unit 3 to prevent the round bottles leaving the screw bottle-separating mechanism 5 from falling.

[0030] The lower end of the adjusting device includes a movable plate 504 and a first fixed plate 502. The first fixed plate 502 is vertically fixed to one side of the conveyor unit 3, and has a transverse connecting hole. The movable plate 504 is horizontally provided with left and right connecting parts 503, and is horizontally connected to the first fixed plate 502 through the transverse connecting hole. The left and right connecting parts 503 are threaded screws, and guide rods are provided next to the left and right connecting parts. A left and right adjustment knob 505 is provided on the side of the movable plate 504 away from the left and right connecting parts 503. By rotating the left and right adjustment knob 505, the left and right connecting parts 503 are rotated and moved forward, so that the movable plate 504 moves axially with the left and right connecting parts 503, thereby controlling the distance between the screw bottle separating mechanism 5 and the conveyor unit 3. The upper end of the adjusting device includes a second fixed plate 508. The second fixed plate 508 is vertically fixed to the side of the mounting plate 509 away from the conveyor unit 3, and has a vertical connecting hole at its lower end. A vertical upper and lower connecting member 506 is provided above the movable plate 504, and a second fixed plate 508 is connected to it through a vertical connecting hole. The upper and lower connecting member 506 is a threaded screw, and a guide rod is provided next to the upper and lower connecting member 506. An upper and lower adjustment knob 507 is provided on the side of the movable plate 504 away from the upper and lower connecting member 506. By rotating the upper and lower adjustment knob 507, the upper and lower connecting member 506 is rotated and moved upward, so that the second fixed plate 508 is axially translated with the upper and lower connecting member 506, thereby controlling the height of the screw bottle separating mechanism 5 from the conveyor line unit 3.

[0031] The driving device includes a screw motor 510, a motor drive wheel 511, and a screw drive wheel 512. The screw motor 510 is connected to the short plate 515 of the mounting plate 509 and is located on the same side as the second fixed plate 508. The motor drive wheel 511 and the screw drive wheel 512 are arranged on the outer side of the short plate 515 of the mounting plate 509. The screw motor 510 passes through the short plate 515 of the mounting plate 509 and is connected to the motor drive wheel 511. The screw 501 passes through the short plate 515 of the mounting plate 509 and is connected to the screw drive wheel 512. Both the motor drive wheel 511 and the screw drive wheel 512 are gears with spur teeth of the same size. The motor drive wheel 511 and the screw drive wheel 512 are connected by a screw drive belt 513. The inner ring of the screw drive belt 513 has spur teeth of the same size as the motor drive wheel 511 and the screw drive wheel 512. The screw motor 510 rotates the motor drive wheel 511, which in turn drives the screw drive belt 513, which in turn drives the screw drive wheel 512, causing the screw 501 to be driven and rotate at a certain speed.

[0032] like Figure 1As shown, the feeding disc 1 includes an anti-drop guardrail 101, a handle 102, a baffle 103, a feeding plate 104, and an adjusting device 105. The feeding disc 1 is connected to the front end of the conveyor line unit 3 via the adjusting device 105 and is placed horizontally. It has an anti-drop guardrail 101 and an opening around its perimeter. A horizontally fixed handle 102 and baffle 103 are positioned above the feeding disc 1. The length of the baffle 103 is the same as the radius of the feeding disc 1. One end of the baffle 103 is fixed to the center of the feeding disc 1 and rotates counterclockwise. The feeding plate 104 is located at the end of the feeding disc 1 furthest from the conveyor line unit 3. The size of the feeding plate 104 is the same as the size of the opening of the anti-drop guardrail. When the opening of the anti-drop guardrail is aligned with the feeding plate 104, round bottles can be fed to the feeding disc 1 through the feeding plate 104. By engaging the handle 102 with the baffle 103, the round bottle on the feeding disc 1 is fed into the conveyor line unit 3 via the adjusting device 105.

[0033] The bottle rejection mechanism 4 is connected to the conveyor line unit 3 and is located between the feeding disc 1 and the screw bottle separating mechanism 5. The bottle rejection mechanism 4 is an arc-shaped conveyor line with bottle rejection plates on both sides. A bottle collection device or bottle output device (not shown in the figure) is provided below the bottle rejection mechanism 4. Vertical bottles, due to their flat bottoms, can be smoothly conveyed along the conveyor line unit 3. Inverted bottles, due to their round curved surface structure, will roll on the conveyor line unit 3 when passing through the arc-shaped conveyor line on the bottle rejection mechanism 4 and eventually slide off the conveyor line unit 3 into the bottle collection device or bottle output device.

[0034] The sensors include a missing print detection sensor 7 and a missing label detection sensor 11. The missing print detection sensor 7 is located above the conveyor line unit 3 and between the labeling host unit 6 and the wheel attachment mechanism 8, and is used to detect labels without printed text. The missing label detection sensor 11 is located between the wheel attachment mechanism 8 and the cylinder rejection mechanism 10, and is used to detect round bottles without labels. The cylinder rejection mechanism 10 includes a rejection plate and a cylinder connected to the rejection plate. The rejection plate and the cylinder cooperate to reject the labels without printed text and the round bottles without labels detected by the sensors.

[0035] The screw-type bottle labeling machine for round bottles also includes a chassis unit 2, a human-machine interface unit 9, and an encoder mechanism 12. The chassis unit 2 is located below the conveyor line unit 3 and is used to assemble the entire chassis structure of the screw-type bottle labeling machine and drive its operation. The human-machine interface unit 9 is located above the chassis unit 2, allowing the user to control the operation of the entire screw-type bottle labeling machine. The encoder mechanism 12 is located at the tail end of the conveyor line unit 3 and is used to encode the round bottles that have been labeled and passed inspection.

[0036] During operation, the lengths of the left-right connecting parts 503 and the up-down connecting parts 506 are changed by rotating the left-right adjustment knob 505 and the up-down adjustment knob 507, and the positions of the moving plate 504 and the second fixed plate 508 are adjusted, thereby adjusting the position of the screw bottle separating mechanism 5 from the conveyor line unit 3, so that the screw bottle separating mechanism 5 is adjusted to a suitable position for the round bottles on the conveyor line unit 3. Then, the model of the screw 501 is adjusted so that the thread pitch of the screw 501 is consistent with the size of the round bottles to be labeled. After the adjustment is completed, the entire screw bottle separating round bottle labeling machine is started through the human-machine interface unit 9. The round bottles first enter the feeding disc 1 through the feeding plate 104 and are dispersed on the feeding disc 1. By rotating the baffle 103 counterclockwise, the handle 102 and the baffle 103 push the round bottles, and the dispersed round bottles are sequentially passed one after another through the adjusting device 105 into the conveyor line unit 3. The conveyor belt of conveyor unit 3 transports the round bottles from left to right. When the bottles pass the bottle-removing mechanism 4, the fallen bottles are automatically removed by the curved conveyor line, while the upright bottles continue to move to the right. Upon passing the screw-separating mechanism 5, adjacent bottles are separated by the threads on the screw 501 and continue to be transported with the rotating screw 501, creating a uniform spacing between the bottles. The separated bottles pass through the labeling host unit 6 and are automatically labeled. They then immediately enter the wheel-attaching mechanism 8, where the labels are smoothly affixed to the bottle surface. The labeled bottles are transported to the cylinder-removing mechanism 10, which removes all bottles that are not labeled (detected by the missing label sensor 11) and bottles that are missing print (detected by the missing print sensor 7). Labeled and qualified bottles are then transported to the encoder mechanism 12 for encoding. The screw 501 separates the bottles, making the separation more accurate.

[0037] The advantages of this utility model are as follows: Through the screw bottle separating mechanism 5 and its screw 501, mounting plate 509, adjusting device and driving device, the screw 501 is installed on one side of the mounting plate 509 and opposite to the conveyor unit 3. The upper end of the adjusting device is installed on the other side of the mounting plate 509, and the lower end of the adjusting device is installed on the conveyor unit 3. The position of the screw 501 is adjusted by the adjusting device cooperating with the conveyor unit 3, so that when the round bottle enters the screw bottle separating mechanism, the round bottle is separated by the thread on the screw 501, and a certain uniform spacing is formed between the round bottles, making the bottle separation more accurate, the labeling more stable, and the production efficiency higher.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
