In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0031] refer to Figures 1 to 3 An embodiment of the present application provides an automatic bottle turning device 100 that can meet the turning requirements of special-shaped bottles.

[0032] The automatic bottle rotating device 100 includes a frame 10, at least one conveyor line 20, at least one bottle-rubbing mechanism (specifically, a first bottle-rubbing mechanism 30 and a second bottle-rubbing mechanism 40), and a lifting and adjusting mechanism 50. The conveyor line 20 is mounted on the frame 10 and is used to transport filled bottles 200 along a first horizontal direction X. The bottle-rubbing mechanism includes a first drive belt 311 and a second drive belt 321 that operate at differential speeds. The first and second drive belts 311 and 321 are spaced apart in a second horizontal direction Y. The lifting and adjusting mechanism 50 is mounted on the frame 10 and includes a first lift drive assembly 510, a second lift drive assembly 520 driven by the first lift drive assembly 510, and a crossbeam 530. The crossbeam 530 is connected to a first lifting end 511 of the first lift drive assembly 510 and to a second lifting end 521 of the second lift drive assembly 520. The crossbeam 530 spans above the conveyor line 20 along the second horizontal direction Y and is connected to the bottle-rubbing mechanism. The second horizontal direction Y is perpendicular to the first horizontal direction X.

[0033] The frame 10 serves as the mounting base for other components or elements of the automatic bottle rotating device 100. Both ends of the frame 10 in the first horizontal direction X are open, allowing for docking with other conveying equipment upstream or downstream of the conveyor line 20. A control cabinet 110 is also located at the bottom of the frame 10. The control cabinet 110 controls the operation of the conveyor line 20, the bottle-cleaning mechanism, and the lifting and adjusting mechanism 50. A protective cover 120 is located at the top of the frame 10. The protective cover 120 encloses the bottle-cleaning mechanism and the lifting and adjusting mechanism 50. The protective cover 120 includes one or more sliding doors. An alarm 130 is mounted at one end of the frame 10 in the first horizontal direction X. The alarm 130 is in communication with the control cabinet 110. The alarm 130 is configured to sound an alarm when the sliding door is opened. The control cabinet 110 is configured to shut down the automatic bottle rotating device 100 when the sliding door is opened.

[0034] The conveyor line 20 is disposed on the frame. The specific type of the conveyor line 20 is not limited. Optionally, the conveyor line 20 is a chain plate conveyor line or a belt conveyor line. The conveyor line is configured to convey the filled bottles 200 in a first horizontal direction X so that the filled bottles 200 can move to the bottle-rubbing mechanism.

[0035] refer to Figure 2 、 Figure 4 The bottle-rubbing mechanisms are arranged one-to-one with the conveyor lines 20. For example, the present application includes two conveyor lines 20 arranged side by side in the second horizontal direction Y, each of which is equipped with a bottle-rubbing mechanism. The two bottle-rubbing mechanisms are staggered in the first horizontal direction X and also in the second horizontal direction Y.

[0036] The first transmission belt 311 and the second transmission belt 321 of the bottle-rubbing mechanism are spaced apart in the second horizontal direction Y. The first transmission belt 311 and the second transmission belt 321 are configured to have different belt speeds. Optionally, the first transmission belt 311 and the second transmission belt 321 are each independently configured with a drive assembly to achieve different belt speeds. Optionally, the first transmission belt 311 and the second transmission belt 321 share a drive assembly, and the different speeds are achieved by configuring reduction mechanisms with different speed ratios.

[0037] A gap exists between the first and second drive belts 311, 321. This gap accommodates the diameter of the mouth of the filling bottle 200. The first and second drive belts 311, 321 hold the mouth of the filling bottle 200 between them. Due to the different speeds of the first and second drive belts 311, 321 can twist and turn the filling bottle 200, achieving a desired direction.

[0038] refer to Figure 1 、 Figure 4 The lifting and adjusting mechanism 50 is used to drive the bottle-rubbing mechanism to rise and fall in the height direction Z of the frame. Therefore, when the conveyor line 20 conveys other types of filled bottles 200, the lifting and adjusting mechanism 50 drives the bottle-rubbing mechanism to rise and fall in the height direction Z of the frame, so that the first transmission belt 311 and the second transmission belt 321 can still act on the bottle mouths of the filled bottles 200, thereby rubbing and rotating the filled bottles 200.

[0039] The first and second lift drive assemblies 510, 520 of the lift adjustment mechanism 50 are located on either side of the conveyor line 20 in the second horizontal direction Y. A crossbeam 530 spans the conveyor line 20 in the second horizontal direction Y and is connected to the bottle-rubbing mechanism. The second lift drive assembly 520 is driven by the first lift drive assembly 510. This ensures that both ends of the crossbeam 530 in the second horizontal direction Y move in synchrony with the frame's height direction Z, ensuring that the first and second drive belts 311, 321 can still accurately engage the necks of the bottles 200.

[0040] In the present application, corresponding to the two bottle-rubbing mechanisms, the number of the crossbeams 530 is 2. In other embodiments, the two bottle-rubbing mechanisms can also be provided on the same crossbeam 530 .

[0041] In the present application, the lifting and adjusting mechanism 50 drives the bottle rubbing mechanism to rise and fall, so that the first transmission belt 311 and the second transmission belt 321 act on the bottle mouth position of the filling bottles 200 of different bottle types. When the first transmission belt 311 and the second transmission belt 321 move at a differential speed, they can drive the filling bottles 200 to turn, thereby meeting the turning requirements of filling bottles 200 of different bottle types.

[0042] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0043] In some embodiments, such as Figures 5 to 8 As shown, the first lifting drive assembly 510 also includes a first mounting bracket 512 and a first lead screw 513. The first mounting bracket 512 is fixed to the frame. The axial direction of the first lead screw 513 is along the height direction Z of the frame and is relatively rotatable with the first mounting bracket 512, and the first lifting end 511 is screwed with the first lead screw 513. The second lifting drive assembly 520 also includes a second mounting bracket 522, a second lead screw 523, and a second lifting end 521. The second mounting bracket 522 is fixed to the frame. The axial direction of the second lead screw 523 is along the height direction Z of the frame and is relatively rotatable with the second mounting bracket 522, and the second lifting end 521 is screwed with the second lead screw 523; the lifting adjustment mechanism 50 also includes a transmission assembly 540, which transmits and connects the first lead screw 513 and the second lead screw 523.

[0044] When the first screw 513 rotates, it drives the first lifting end 511 up and down. Simultaneously, the first screw 513 drives the second screw 523 to rotate in the same direction via the transmission assembly 540. The rotation of the second screw 523 drives the second lifting end 521 up and down. In this way, the first and second lifting ends 511 and 521 rise or fall synchronously, effortlessly driving the crossbeam 530 up or down.

[0045] Optionally, the first mounting frame 512 includes a first base 5121, two first guide rods 5122, and a first top beam 5123. The two first guide rods 5122 are arranged along the height direction Z of the frame, and are spaced apart at both ends of the first base 5121 in the second horizontal direction Y. The first top beam 5123 is fixed to the top of the two first guide rods 5122. The two ends of the first lifting end 511 are respectively slidably matched with the two first guide rods 5122. The top and bottom ends of the first lead screw 513 are respectively rotatably connected to the first base 5121 and the first top beam 5123 through bearings, and the middle part of the first lead screw 513 is passed through and is on the first lifting end 511. Therefore, when the first lead screw 513 is rotated, the first lead screw 513 can drive the first lifting end 511 to rise and fall.

[0046] The second mounting frame 522 includes a second base 5221, two second guide rods 5222, and a second top beam 5223. The two second guide rods 5222 are arranged along the height direction Z of the frame and are spaced apart at both ends of the second base 5221 in the second horizontal direction Y. The second top beam 5223 is fixed to the top of the two second guide rods 5222. The two ends of the second lifting end 521 are respectively slidably engaged with the two second guide rods 5222. The top and bottom ends of the second lead screw 523 are respectively rotatably engaged with the second base 5221 and the second top beam 5223 via bearings, and the middle part of the second lead screw 523 is passed through the second lifting end 521. Therefore, when the second lead screw 523 is rotated, the second lead screw 523 can drive the second lifting end 521 to move up and down.

[0047] In some embodiments, the transmission assembly 540 includes a first sprocket 541, a second sprocket 542, and a chain 543. The first sprocket 541 is fixed to the first lead screw 513, and the second sprocket 542 is fixed to the second lead screw 523. The first sprocket 541 is disposed at the top of the first lead screw 513. The second sprocket 542 is disposed at the top of the second lead screw 523. The chain 543 is wound around the first sprocket 541 and the second sprocket 542 to form a closed loop.

[0048] Furthermore, the transmission assembly 540 also includes a connecting beam 544. The connecting beam 544 is arranged along the second horizontal direction Y, and its ends are respectively fixed to the first top beam 5123 and the second top beam 5223. The top of the connecting beam 544 forms a groove. The top of the first lead screw 513, the top of the second lead screw 523, the first sprocket 541, the second sprocket 542, and the chain 543 are all disposed in the groove and protected by the side walls of the groove.

[0049] Furthermore, transmission assembly 540 includes a tensioning wheel (unnumbered) and an adjustment rod (unnumbered). The tensioning wheel is disposed in a groove and abuts against chain 543. The adjustment rod is relatively movably disposed on the sidewall of the groove and is connected to the tensioning wheel. The adjustment rod is used to adjust the pressure applied by the tensioning wheel to chain 543, thereby tensioning chain 543.

[0050] In some embodiments, the first mounting bracket 512 includes a support platform 5124 having an operating space, and the bottom end of the first lead screw 513 extends into the operating space.

[0051] Specifically, a support platform 5124 is provided on the first base 5121. An operating space is formed below the surface of the support platform 5124. The bottom end of the first lead screw 513 passes through the surface of the support platform 5124 and extends into the operating space. This makes it convenient for the user to rotate the first lead screw 513.

[0052] Furthermore, an operating handle 514 is sleeved on the bottom end of the first lead screw 513. The operating handle 514 is located in the operating space. The user extends his hand into the operating space and then holds the operating handle 514.

[0053] In some embodiments, the lifting and adjusting mechanism 50 further includes an anti-rotation fixing assembly 550. The anti-rotation fixing assembly 550 includes a mounting seat 551 and a clamping mechanism 552, wherein the mounting seat 551 is fixed to the support platform 5124, the first lead screw 513 is passed through the mounting seat 551, and the clamping mechanism 552 is movably connected to the mounting seat 551, and the clamping mechanism 552 is used to clamp or release the first lead screw 513.

[0054] Optionally, the mounting seat 551 is threadedly connected to a bearing seat 553 for supporting a bearing on the first lead screw 513. The clamping mechanism 552 includes a pair of claws that can be relatively close to or separated.

[0055] By providing the anti-rotation fixing assembly 550 , when the height of the bottle rubbing mechanism does not need to be adjusted, the anti-rotation fixing assembly 550 can hold the first screw 513 tightly, thereby preventing the first screw 513 from rotating and maintaining the height of the bottle rubbing mechanism unchanged.

[0056] In some embodiments, reference Figures 9 to 11The bottle-rubbing mechanism includes a first bottle-rubbing mechanism 30 and a second bottle-rubbing mechanism 40. The first bottle-rubbing mechanism 30 includes: a first base 312, a first driving wheel 313 mounted on the first base 312, a first driven wheel 314, a second drive motor 325, and a first transmission belt 311; a second base 322, a second driving wheel 323 mounted on the second base 322, a second driven wheel 324, a second drive motor 325, and a second transmission belt 321. The first driving wheel 313 is in driving connection with the output shaft of the first drive motor 315, and the first transmission belt 311 is in driving connection with the first driving wheel 313 and the first driven wheel 314; the second driving wheel 323 is in driving connection with the output shaft of the second drive motor 325, and the second transmission belt 321 is in driving connection with the second driving wheel 323 and the second driven wheel 324. The first base 312 is further equipped with a tensioning mechanism 330 . The tensioning mechanism 330 is disposed on a side of the first transmission belt 311 facing away from the second transmission belt 321 . The tensioning mechanism 330 abuts against the first transmission belt 311 along the second horizontal direction Y.

[0057] When the mouth of the filling bottle 200 moves between the first transmission belt 311 and the second transmission belt 321, under the action of the tensioning mechanism 330, the first transmission belt 311 can press the mouth of the filling bottle 200, so that the first transmission belt 311 and the second transmission belt 321 clamp the mouth of the filling bottle 200, and then the first transmission belt 311 and the second transmission belt 321 rub the filling bottle 200 to turn.

[0058] Optionally, the structure of the second bottle rubbing mechanism 40 may be the same as that of the first bottle rubbing mechanism 30. Optionally, the second bottle rubbing mechanism 40 differs from the first bottle rubbing mechanism 30 only in that the tensioning mechanism 330 is not provided.

[0059] In some embodiments, the tensioning mechanism 330 includes a guide bar 331 and an elastic member 332. The guide bar 331 rests on the first transmission belt 311. The guide bar 331 is movably connected to the mounting seat 551 in the second horizontal direction Y. The elastic member 332 is arranged between the guide bar 331 and the mounting seat 551 and elastically abuts against the guide bar 331.

[0060] The guide bar 331 abuts against the side of the first transmission belt 311 facing away from the second transmission belt 321. The guide bar 331 and the mounting base 551 may be relatively slidable, relatively rotatable, or flexibly connected. The elastic member 332 is configured to elastically abut the guide bar 331, thereby providing a driving force for the guide bar 331 to abut against the first transmission belt 311.

[0061] Through the above arrangement, the guide bar 331 is arranged to float relative to the mounting seat 551, and the guide bar 331 abuts against the first transmission belt 311 under the action of the elastic member 332. Therefore, the automatic bottle rotating device 100 of the present application can accommodate filling bottles 200 of different bottle shapes and the same bottle neck diameter, as well as filling bottles 200 of different bottle neck diameters.

[0062] Optionally, one of the mounting seat 551 and the guide bar 331 is provided with a guide groove 3121 , and the other is provided with a matching guide pin 333 .

[0063] In the present application, a guide slot 3121 is provided in the mounting seat 551. A guide pin 333 is connected to the guide bar 331. The guide pin 333 is inserted into the guide slot 3121 and slidably engages with the guide slot 3121 in the second horizontal direction Y. The cooperation between the guide pin 333 and the guide slot 3121 allows the guide bar 331 to float relative to the mounting seat 551 while also guiding its movement. This ensures that the elastic force of the elastic member 332 is transmitted through the guide bar 331 to the first transmission belt 311.

[0064] In some embodiments, reference Figure 2 The automatic bottle rotating device 100 also includes a first guardrail 610 and a second guardrail 620 arranged on both sides of the conveyor line 20 in the second horizontal direction Y, and an adjustment mechanism 630 that drives at least one of the first guardrail 610 and the second guardrail 620 to move in the second horizontal direction Y.

[0065] The adjustment mechanism 630 is used to adjust the movement of at least one of the first guardrail 610 and the second guardrail 620 to change the distance between the first guardrail 610 and the second guardrail 620 to accommodate filling bottles 200 of different sizes. The adjustment mechanism 630 can be, for example, a screw adjustment mechanism, an electric push rod, etc.

[0066] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.
