[0065] The above technical solution is adopted to facilitate the driving plate to move downward to contact the sliding plate so that the straight rod drives the connecting rod and the push rod to move downward, so that the vertical plate and the limit rod move to the right, release the limit on the horizontal plate, and ensure that the piston is reset downward by releasing the first spring.

[0066] A method for using an automatic pick-up beverage production bottle cap tightening device, comprising the following steps:

[0067] Step 1: Start the electric telescopic rod to move the driving plate and the driving rod upward. When the driving rod moves to the oblique position of the driving slot, the rotating rod will rotate during the upward movement of the driving rod until the driving rod moves to the vertical position above the driving slot. At this time, the rotating rod and the mounting plate rotate 180 degrees, so that the tightening head is placed above the end of the guide rail;

[0068] Step 2: The driving plate is continuously moved upward by the electric telescopic rod. At this time, the driving rod moves upward in the vertical groove above the driving groove to ensure that the rotating rod does not rotate any more. When the driving plate moving upward contacts the horizontal plate, it pushes the horizontal plate upward and compresses the first spring, so that the sliding rod and the piston move upward, thereby extracting through the suction pipe, the air pipe and the through pipe, and then adsorbing the bottle cap at the end of the guide rail upward to the inside of the tightening head, and clamping and fixing it by the pneumatic clamping block arranged on the inner wall of the tightening head;

[0069] Step 3: When the horizontal plate moves upward, it will contact the limit rod, causing the limit rod to move to the right, so that the vertical plate moves to the right synchronously to stretch the tension spring. After the upwardly moving horizontal plate separates from the limit rod, the horizontal plate and the limit rod are pulled back to the left by the tension spring, so that the horizontal plate is limited;

[0070] Step 4: The driving plate and the driving rod are reset and moved downward by the electric telescopic rod. At this time, the limiting rod limits the horizontal plate to ensure that the bottle cap is stably and effectively adsorbed in the tightening head. When the driving rod moves downward to the oblique groove of the driving groove, the rotating rod and the mounting plate are reset and rotated until the driving rod is placed in the vertical groove below the driving groove, so that the rotating rod and the mounting plate are reset;

[0071] Step 5: Drive the horizontal cylinder to move the clamp block so that the beverage bottle conveyed by the conveyor belt is positioned and clamped, and drive the vertical cylinder to move the clamped beverage bottle upward, and start the motor to rotate the driving gear at the same time. The driven gear causes the mounting rod and the tightening head to rotate, ensuring that the adsorbed bottle cap rotates stably under the clamping and fixing of the silicone sheet and the pneumatic clamp block, and the lifting and lowering movement of the positioned and clamped beverage bottle is completed to tighten the bottle cap on the beverage bottle;

[0072] Step 6: Then the driving plate is continuously moved downward by the electric telescopic rod. At this time, the driving rod moves downward in the vertical groove below the driving groove to ensure that the rotating rod and the mounting plate do not rotate. After the driving plate moves downward and contacts the sliding plate, the sliding plate drives the connecting plate and the push rod to move downward through the straight rod and compresses the second spring. When the push rod moves downward, it pushes the vertical plate and the limit rod to move to the right. When the limit rod is separated from the horizontal plate, the horizontal plate drives the sliding rod and the piston to reset downward under the release action of the first spring, thereby releasing the adsorption and fixing effect on the bottle cap, and the beverage bottle can be placed on the conveyor belt for transportation again;

[0073] Step 7: The driving plate and the driving rod are moved upward to the initial position again by the electric telescopic rod, so that the sliding plate is reset upward under the release of the second spring, thereby resetting the straight rod, the connecting plate and the push rod upward, ensuring the next step of tightening the bottle cap onto the beverage bottle.

[0074] Compared with the prior art, the beneficial effects of the present invention are as follows: the automatic picking-up beverage production bottle cap tightening device can automatically pick up the bottle cap and tighten it with the bottle body, solving the problem that the existing bottle cap is not only low in precision but also easy to fall off when conveying and feeding the bottle cap to the bottle body, thereby ensuring that the bottle cap and the bottle body are tightened stably and effectively during the beverage production process, and the operation is simple and flexible, and the degree of automation is high;

[0075] 1. The driving plate and the driving rod are controlled to move up and down by starting the electric telescopic rod, so that the rotation of the rotating rod and the mounting plate can be realized through the cooperation of the driving rod and the driving slot, and the mounting plate can be ensured to drive the mounting rod and the tightening head to be placed above the end of the guide rail;

[0076] 2. After the driving plate moves upward and contacts the horizontal plate, the slide rod and the piston move upward, and the bottle cap can be adsorbed into the tightening head through the suction pipe, the hose and the through pipe. At the same time, after the horizontal plate moves upward and contacts the limit rod, the limit rod moves to the right. After the horizontal plate moves upward and separates from the limit rod, the vertical plate drives the limit rod to move in a limited manner under the action of the tension spring, so that the limit rod limits the horizontal plate;

[0077] 3. When the electric telescopic rod drives the driving plate and the driving rod to move downward, the rotating rod drives the mounting plate to reset and move, the bottle body is clamped and fixed by the horizontal cylinder, and the vertical cylinder is used to move it up and down, and the motor is driven to make the driving gear active, and the driven gear drives the mounting rod and the tightening head to rotate, so that the bottle cap is tightened onto the bottle body;

[0078] 4. After the driving plate moves downward again to contact the sliding plate, the straight rod drives the connecting plate and the push rod to move downward, so that the vertical plate and the limit rod move to the right, thereby releasing the limit on the horizontal plate, so that the horizontal plate drives the sliding rod and the piston to return downward through the release action of the first spring, so that it can be used again in the future.

[0096] A method for using an automatic pick-up beverage production bottle cap tightening device, comprising the following steps:

[0097] Step 1: Start the electric telescopic rod 11 to move the driving plate 12 and the driving rod 13 upward. When the driving rod 13 moves to the oblique position of the driving slot 15, the rotating rod 14 will rotate during the upward movement of the driving rod 13 until the driving rod 13 moves to the vertical position above the driving slot 15. At this time, the rotating rod 14 and the mounting plate 16 rotate 180 degrees, so that the tightening head 21 is placed above the end of the guide rail 6;

[0098] Step 2: The driving plate 12 is continuously moved upward by the electric telescopic rod 11. At this time, the driving rod 13 moves upward in the vertical groove above the driving groove 15 to ensure that the rotating rod 14 does not rotate any more. When the driving plate 12 moving upward contacts the horizontal plate 26, the horizontal plate 26 is pushed to move upward and the first spring 31 is compressed, so that the sliding rod 25 and the piston 27 move upward, thereby extracting through the suction pipe 28, the hose 29 and the through pipe 30, and then the bottle cap at the end of the guide rail 6 is adsorbed upward to the inside of the tightening head 21, and is clamped and fixed by the pneumatic clamping block provided on the inner wall of the tightening head;

[0099] Step 3: When the horizontal plate 26 moves upward, it will contact the limiting rod 32, causing the limiting rod 32 to move to the right, so that the vertical plate 33 moves to the right synchronously to stretch the tension spring 34. After the horizontal plate 26 that moves upward separates from the limiting rod 32, the vertical plate 33 and the limiting rod 32 are pulled by the tension spring 34 to return to the left, so that the horizontal plate 26 is limited.

[0100] Step 4: The driving plate 12 and the driving rod 13 are reset and moved downward by the electric telescopic rod 11. At this time, the limiting rod 32 limits the horizontal plate 26 to ensure that the bottle cap is stably and effectively adsorbed in the tightening head 21. When the driving rod 13 moves downward to the oblique groove of the driving groove 15, the rotating rod 14 and the mounting plate 16 are reset and rotated until the driving rod 12 is placed in the vertical groove below the driving groove 15, so that the rotating rod 14 and the mounting plate 16 are reset;

[0102] Step 6: Then, the driving plate 12 is continuously moved downward by the electric telescopic rod 11. At this time, the driving rod 13 moves downward in the vertical groove below the driving groove 15 to ensure that the rotating rod 14 and the mounting plate 16 do not rotate. After the driving plate 12 moves downward and contacts the sliding plate 36, the sliding plate 36 drives the connecting plate 38 and the push rod 39 to move downward through the straight rod 37 and compress the second spring 40. When the push rod 39 moves downward, it pushes the vertical plate 33 and the limiting rod 32 to move rightward. When the limiting rod 32 is separated from the horizontal plate 26, the horizontal plate 26 drives the sliding rod 25 and the piston 27 to reset downward under the release action of the first spring 31, thereby releasing the adsorption and fixing effect on the bottle cap, and the beverage bottle can be placed on the conveyor belt 3 for transportation again;

[0103] Step 7: The driving plate 12 and the driving rod 13 are moved upward to the initial position again by the electric telescopic rod 11, so that the sliding plate 36 is reset upward under the release of the second spring 40, thereby the straight rod 37, the connecting plate 38 and the push rod 39 are reset upward to ensure the next step of tightening the bottle cap onto the beverage bottle.

9. A method for using an automatic pick-up beverage production bottle cap tightening device, characterized in that: The following steps are involved: Step 1: Start the electric telescopic rod (11) to move the driving plate (12) and the driving rod (13) upward. When the driving rod (13) moves to the oblique position of the driving groove (15), the rotating rod (14) will rotate during the upward movement of the driving rod (13) until the driving rod (13) moves to the vertical position above the driving groove (15). At this time, the rotating rod (14) and the mounting plate (16) rotate 180 degrees, so that the tightening head (21) is placed above the end of the guide rail (6); Step 2: The driving plate (12) is continuously moved upward by the electric telescopic rod (11). At this time, the driving rod (13) moves upward in the vertical groove above the driving groove (15) to ensure that the rotating rod (14) no longer rotates. When the driving plate (12) moving upward contacts the horizontal plate (26), the horizontal plate (26) is pushed to move upward and the first spring (31) is compressed, so that the sliding rod (25) and the piston (27) move upward, thereby extracting through the suction pipe (28), the hose (29) and the through pipe (30), and then the bottle cap at the end of the guide rail (6) is sucked upward to the inside of the tightening head (21), and is clamped and fixed by the pneumatic clamping block arranged on the inner wall of the tightening head (21); Step 3: When the horizontal plate (26) moves upward, it contacts the limiting rod (32), causing the limiting rod (32) to move to the right, so that the vertical plate (33) moves to the right synchronously to stretch the tension spring (34). After the horizontal plate (26) that moves upward separates from the limiting rod (32), the vertical plate (33) and the limiting rod (32) are pulled to the left by the tension spring (34), so that the horizontal plate (26) is limited. Step 4: The driving plate (12) and the driving rod (13) are reset and moved downward by the electric telescopic rod (11). At this time, the limiting rod (32) limits the horizontal plate (26) to ensure that the bottle cap is stably and effectively adsorbed in the tightening head (21). When the driving rod (13) moves downward to the oblique groove of the driving groove (15), the rotating rod (14) and the mounting plate (16) are reset and rotated until the driving rod (12) is placed in the vertical groove below the driving groove (15), so that the rotating rod (14) and the mounting plate (16) are reset; Step 5: The clamping block (9) is moved by driving the horizontal cylinder (8) to position and clamp the beverage bottle conveyed by the conveyor belt (3), and the vertical cylinder (7) is driven to move the clamped beverage bottle upward, and at the same time, the motor (17) is started to rotate the driving gear (18), and the installation rod (19) and the tightening head (21) are rotated through the action of the driven gear (20), so as to ensure that the adsorbed bottle cap can rotate stably under the action of the silicone sheet (22) and the pneumatic clamping block, and the bottle cap is tightened on the beverage bottle in coordination with the lifting and lowering movement of the positioned and clamped beverage bottle; Step 6: Then, the driving plate (12) is continuously moved downward by the electric telescopic rod (11). At this time, the driving rod (13) moves downward in the vertical groove below the driving groove (15) to ensure that the rotating rod (14) and the mounting plate (16) do not rotate. After the driving plate (12) moves downward and contacts the sliding plate (36), the sliding plate (36) drives the connecting plate (38) and the push rod (39) to move downward through the straight rod (37) and compress the second spring (40). When the push rod (39) moves downward, it pushes the vertical plate (33) and the limiting rod (32) to move rightward, so that when the limiting rod (32) is separated from the horizontal plate (26), the horizontal plate (26) drives the sliding rod (25) and the piston (27) to move downward under the release action of the first spring (31), thereby releasing the adsorption and fixing effect on the bottle cap, and the beverage bottle can be placed on the conveyor belt (3) for transportation again; Step 7: The driving plate (12) and the driving rod (13) are moved upward to the initial position again by the electric telescopic rod (11), so that the sliding plate (36) is reset upward under the release action of the second spring (40), thereby causing the straight rod (37), the connecting plate (38) and the push rod (39) to reset upward, thereby ensuring the next step of tightening the bottle cap onto the beverage bottle.
