Cleaning is a very critical first process, generally using ultrasonic, multi-pass spray water washing, and air blowing. The traditional bottle washing machines currently used in the market are one type of disc vertical ultrasonic bottle washing machine and the other type of linear ultrasonic bottle washing machine.

[0003] The disc vertical bottle washing machine has a large diameter of the gear inside the driving disc and is equipped with a mechanical arm telescopic cam, a flip mechanism, etc., so it is large in size and weight, has a large inertia during operation, and is subject to shaking and vibration, and is noisy. It also requires a large torque motor to start and stop the machine. The mechanical structure has many lubrication surfaces, which is prone to secondary oil pollution. Its needle tracking mechanism also has the above problems, and has low tracking accuracy, is easy to misalign, and the needle cannot be inserted into the bottle mouth, so a guide sleeve must be added at the bottle mouth. In general, the mechanical motion mechanism is complex, large in size and weight, consumes a lot of energy, and has a high manufacturing cost. The linear bottle washing machine also has certain cleaning effect problems.

[0033] like Figure 1 The figure shows a linear bottle washing machine, which comprises: a frame assembly 100, wherein the frame assembly 100 comprises a first frame 110 and a second frame 120 from bottom to top;

[0034] A synchronous belt bottle conveying mechanism 200 installed on the second frame 120, the synchronous belt bottle conveying mechanism 200 comprises a driving synchronous belt pulley 210 and a driven synchronous belt pulley 220 connected to the driving synchronous belt pulley 210 through a synchronous belt 230, a plurality of bottle clamping members 240 for clamping the bottle body are fixedly arranged on the outer transmission surface of the synchronous belt 230, and the plurality of bottle clamping members 240 are arranged in a straight line at a preset distance;

[0035] A spray cleaning mechanism 300 installed on the first frame 110, the spray cleaning mechanism 300 includes a cleaning assembly 310, a reciprocating drive assembly 320 and a lifting assembly 330;

[0036] The cleaning assembly 310 includes spray needles 311 arranged on a needle holder 312 at a linear interval at the preset distance.

[0037] The reciprocating drive assembly 320 includes a guide rail 321 and a first drive arm 322 connected to the needle holder 312. The needle holder 312 is slidably disposed on the guide rail 321 and reciprocates along the guide rail 321 under the action of the first drive arm 322.

[0038] The lifting assembly 330 includes a lifting shaft 331 fixed below the guide rail 321, and a connecting shaft 332 laterally hinged to one end of the lifting shaft 331. The other end of the connecting shaft 332 is fixed and a lifting cam 334 is connected between the two ends of the shaft body through a rolling bearing 333. One end of the connecting shaft 332 drives the lifting shaft 331 to move up and down under the rotation of the lifting cam 334.

[0039] Specifically, in the present embodiment, the frame assembly 100 of the linear bottle washing machine is divided into a first frame 110 and a second frame 120 arranged above the first frame 110. The first frame 110 and the second frame 120 can be assembled in an integrated manner, fixedly welded or installed. In a possible implementation, the first frame 110 and the second frame 120 can also be connected by a lifting screw rod 130, for example, arranged at the corner connection position between the first frame 110 and the second frame 120, so that the second frame 120 can be moved relative to the first frame 110 to facilitate the replacement of bottles to be washed of different specifications.

[0040] The driving synchronous pulley 210 and the driven synchronous pulley 220 of the synchronous belt bottle conveying mechanism 200 are respectively arranged at both ends of the second frame 120 and are connected and driven by a synchronous belt 230. On the outer transmission surface of the synchronous belt 230, a plurality of bottle clamping members 240 are arranged at intervals along the transmission direction to clamp the bottle body.

[0041] Preferably, a plurality of bottle clamping members 240 are arranged on the synchronous belt 230 to form a complete circle;

[0042] In some embodiments, the bottle clamping member 240 is an elastic clamping structure. For example, the bottle clamping member 240 includes two symmetrical half-clamps, one end of each of which is a half-gear structure, and the half-gears rotate relative to the center of the half-gear through the meshing action of the half-gears to form an open and clamped state. A transverse spring is also provided on the two half-clamps, and the two half-clamps are formed into a clamping normal state through the action of the spring to adapt to the continuous fixed state required after the bottle is transported.

[0043] Preferably, the connecting end of one of the half clamps is extended in the opposite direction to have a clamp tail, which exists as a driving force-bearing part, so as to cooperate with a lever or cam mechanism to realize opening of the clamp at a specific position. For example, a cam is set at a fixed position through which each bottle clamp 240 is transmitted, and the cam acts on the clamp tail through a protrusion or other force-transmitting member to open the bottle clamp 240, thereby facilitating the loading or unloading of the bottle body.

[0044] The cleaning assembly 310 of the spray cleaning mechanism 300 is located below the synchronous belt bottle conveying mechanism 200, and is connected to the second frame 120 together with the reciprocating transmission assembly and the lifting assembly 330. The cleaning assembly 310 includes a linear needle rack 312, on which a plurality of spray needles 311 having the same spacing as the adjacent bottle bodies (bottle clamping members 240) are mounted. The positions of the spray needles 311 correspond to the openings of the bottle bodies, so that the inside of the bottle bodies can be sprayed and cleaned;

[0045] The reciprocating drive assembly 320 includes a guide rail 321 and a first drive arm 322. The needle holder 312 is slidably disposed on the guide rail 321 and slides back and forth along the guide rail 321. One end of the first drive arm 322 is connected to the needle holder 312 and provides a driving force for the needle holder 312 to slide.

[0046] The other end of the first driving arm 322 can be connected to any reciprocating motion structure to achieve periodic reciprocating motion, thereby driving the needle holder 312 to slide back and forth on the guide rail 321.

[0047] In some embodiments, the present application provides a reciprocating motion structure to achieve the above effect, see Figure 2 , are three views of a reciprocating drive assembly 320 in a linear bottle washing machine in an embodiment of the present application. In this embodiment, the linear bottle washing machine also includes a transmission mechanism 400. The drive motor 410 of the transmission mechanism 400 is arranged on the second frame 120, and the output end is connected to a drive spindle 420. A reciprocating tracking cam 430 is fixedly sleeved on the drive spindle 420. The reciprocating tracking cam 430 is cylindrical and has a circle of completely closed rotating return groove 431 on the circumferential surface (the rotating return groove 431 can be a closed return groove extending upward from the bottom of the cylinder and returning to the starting position around the circumference or a closed return groove formed in other forms that can realize reciprocating motion). The rotating return groove 431 is slidably connected to one end of the second driving arm 440, and the other end of the second driving arm 440 is fixedly connected to the first driving arm 322 through a shaft or a rod.

[0048] When the reciprocating tracking cam 430 rotates following the driving main shaft 420, one end of the second driving arm 440 slides in the rotating return groove 431. Since the position of the reciprocating tracking cam 430 is relatively inconvenient, one end of the second driving arm 440 makes a directional reciprocating motion relative to the reciprocating tracking cam 430 under the sliding action. Accordingly, the second driving arm 440 as a whole and the first driving arm 322 (including the needle holder 312) fixedly connected to the second driving arm 440 make a directional reciprocating motion, thereby realizing the reciprocating motion of the needle holder 312 on the guide rail 321.

[0049] It should be noted that the motion state parameters of the reciprocating motion can be adjusted in association with the corresponding parameters. For example, the reciprocating stroke can be achieved by designing and selecting the specifications of the rotating return groove 431 or the reciprocating tracking cam 430. The longer the groove of the rotating return groove 431 and the larger the volume of the reciprocating tracking cam 430, the larger the reciprocating stroke. In addition, the speed of the reciprocating motion can be adjusted by controlling the rotational speed of the driving spindle 420. The principle is deduced based on the structure and connection relationship, and will not be repeated here.

[0050] In some embodiments, considering that the needle holder 312 needs to drive the spray needle 311 to move up and down slightly to enter and exit the bottle body, the effect of achieving up and down movement while reciprocating by directly connecting with the first driving arm 322 may not be ideal, so a preferred connection method is provided, that is,

[0051] A longitudinal axis 323 is disposed at one end of the first driving arm 322 connected to the needle frame 312 , a transverse axis 313 is fixedly disposed at one side of the needle frame 312 , and one end of the transverse axis 313 is slidably connected to the longitudinal axis 323 via a slider 314 .

[0052] The needle holder 312 and the first driving arm 322 are connected by the intermediate connection of the transverse axis 313, the longitudinal axis 323 and the slider 314, which reduces the resistance of reciprocating motion and up and down motion at the same time, and is more conducive to the synchronous realization of movement in two directions.

[0053] The lifting assembly 330 includes a lifting shaft 331, a connecting shaft 332 and a lifting cam 334, which realizes the principle of the needle holder 312 (cleaning assembly 310) moving up and down to enter or exit the bottle to be washed. Figure 3 Combined with the following explanation, it can be understood that one end of the connecting shaft 332 is fixed, and the middle position is connected to the lifting cam 334 through a rolling bearing 333. When the lifting cam 334 rotates, the height corresponding to its flange will continue to change, and the rolling bearing 333 drives the connecting shaft 332 to make its free end swing. The free end of the connecting shaft 332 is hinged to one end of the lifting shaft 331 fixed under the needle holder 312, thereby converting the swing amplitude into an up and down movement in the vertical direction.

[0054] In the above explanation, the rotation of the lifting cam 334 can be achieved by any rotation drive mode such as setting a rotating motor, but based on the degree of integration of the bottle washing machine and the correlation of various movements, the present application also provides a preferred embodiment, that is,

[0055] The lifting cam 334 is fixedly mounted on the driving main shaft 420 .

[0056] In the aforementioned embodiment, an external power source, namely a drive motor 410 and a drive spindle 420, has been provided as the reciprocating motion of the needle holder 312. In the present embodiment, the drive source can also be used to realize the lifting motion. By fixing the lifting cam 334 on the drive spindle 420, the drive spindle 420 drives the cam to rotate to realize the up and down lifting motion explained above.

[0057] Optionally, as a linear structure, the needle rack 312 needs to be provided with lifting components 330 at multiple positions to maintain balance in order to achieve stable up and down lifting motion. Therefore, the lifting components 330 are preferably provided in multiple groups along the reciprocating motion direction of the needle rack 312, or only through at least one lifting cam 334 and through the connecting shafts 332 between the multiple groups of lifting components 330 through the connecting horizontal axis 335 to achieve synchronous up and down lifting motion.

[0058] In summary of the above embodiments, the linear bottle washing machine of the present application at least provides a linear bottle clamping member 240 on the outer transmission surface of the synchronous belt 230 of the synchronous belt bottle conveying mechanism 200, so that the bottle body can follow the transmission of the synchronous belt 230 under the fixing action of the bottle clamping member 240. Above the synchronous belt 230, the bottle body is fixed by the linear bottle washing machine with the bottle mouth facing upward. After following the synchronous belt 230 to be transmitted to the bottom, the bottle mouth of the bottle body is facing downward. At this time, the cleaning component 310 of the linear spray cleaning mechanism 300 below the synchronous belt bottle conveying mechanism 200 inserts the spray needle 311 into a group of bottles under the action of the reciprocating motion component and the lifting component 330 and follows the movement of the bottle body to perform cleaning synchronously. The bottles to be washed are cleaned during the transmission process; after the cleaning is completed, the spray needle 311 of the spray cleaning mechanism 300 is driven by the lifting component 330 to withdraw from the bottle body and reversely moves to the position of the next group of bottles to be washed under the drive of the reciprocating motion component, and the above cleaning process is repeated. The structure of the linear bottle washing machine of the present application is relatively simple, and the up and down direction change characteristics of the synchronous belt 230 are used to realize the mode of bottle input at the top and cleaning at the bottom, so that the bottle mouths of the bottles to be washed are separated from each other, reducing the possibility of sewage re-entering the bottle during the cleaning process, and effectively avoiding secondary pollution.

[0059] In the above-mentioned embodiment, the coordinated movement of the reciprocating drive component 320 and the lifting component 330 in the spray cleaning mechanism 300 has been realized through the driving motor 410 and the driving spindle 420 of the transmission mechanism 400, so that the spray cleaning mechanism 300 can move up and down while following the movement of the bottle body to enter the inside of the bottle body for cleaning, and after completing the cleaning, it can exit the bottle body and return to the initial position to perform the next set of repeated operations. The integration effect of the spray cleaning component 310 is higher, and the batch cleaning efficiency is improved.

[0060] However, in the aforementioned embodiment, the motion states of the synchronous belt bottle conveying mechanism 200 and the spray cleaning mechanism 300 are still independent of each other. Therefore, based on the application of the characteristics of the transmission mechanism 400, the present application associates it with the synchronous belt bottle conveying mechanism 200 and proposes an implementation method to improve the overall integrated synergy effect of the linear bottle washing machine of the present application, see Figure 4 , specifically, based on the above implementation mode:

[0061] The end of the driving main shaft 420 away from the driving motor 410 is fixedly connected to the first bevel gear 421, and the transmission mechanism 400 also includes a pulley transmission member 450, which includes a second bevel gear 451 arranged on the first frame 110 and meshing with the first bevel gear 421, and a universal joint spline shaft 452 which is vertically arranged and connected to the second bevel gear 451 at one end and to the right angle commutator 453 at the other end, and the other end of the right angle commutator 453 is connected to the axis of the active synchronous pulley 210 and drives the active synchronous pulley 210 to rotate.

[0062] The rotation speed of the driving spindle 420 is used as a determining parameter, and the rotation speed transmitted to the active synchronous pulley 210 (transmission of the synchronous belt 230) is controllable, which can be achieved by adjusting the specifications of the first bevel gear 421 and the second bevel gear 451; the reciprocating motion speed and shape associated with the driving spindle 420 are also controllable, see the explanation in the above embodiment for details; based on the combination of the two, the reciprocating motion of the needle holder 312 can be made the same as the transmission speed of the synchronous belt 230, so that each bottle body can be cleaned more accurately.

[0063] In some embodiments, in order to control the spray needle 311 to be injected and cleaned in a specific motion state and avoid waste of cleaning resources and the possibility of secondary pollution, the present application further provides the following solution: Figure 4 The transmission mechanism 400 also includes a spray opening and closing component 460, which includes a proximity switch 461 sleeved on the driving main shaft 420 and a spray opening and closing signal component 462 fixedly arranged on one side of the proximity switch 461. The spray opening and closing signal component 462 is electrically connected to each spray needle 311, and the proximity switch 461 is a circular ring structure with an opening. When the proximity switch 461 rotates, the spray opening and closing signal component 462 connects or disconnects the circuit to control the injection and spraying of each spray needle 311.

[0064] By associating the proximity switch 461 with the drive spindle 420 (or the rotation speed of the drive spindle 420), in a corresponding structural form, the use of a signal sensor can realize the periodic opening and closing of the spray needle 311, and the device has a higher degree of integration. For example, in an embodiment in which the proximity switch 461 is an open ring structure, the open area is in a state of no signal sensing or transmission. When the proximity switch 461 rotates with the drive spindle 420, the size and shape of the opening area are designed, and the movement state of the cleaning component 310 is matched with the rotation of the drive spindle 420 as an intermediate reference, so that the spray needle 311 is injected and sprayed when the cleaning component 310 moves, and is closed when it retreats.

[0065] In other embodiments, the plurality of bottle clamping members 240 of the cleaning assembly 310 are arranged in two parallel rows on the outer transmission surface of the synchronous belt 230, and the reciprocating drive assembly 320 and the lifting assembly 330 are arranged in two groups corresponding to the two rows of bottle clamping members 240. By arranging in two rows, the efficiency of the bottle washing operation can be doubled using the same power source.

[0066] In other embodiments, the linear bottle washing machine of the present application further includes a washing water tank (not shown in the figure), and the needle holder 312 is connected to the washing water tank to continuously supply liquid to each spray needle 311 .

[0067] In addition, it can be understood that the linear bottle washing machine of the present application can also be used in combination with other bottle conveying mechanisms and output mechanisms to improve the bottle washing production line and achieve full automation, but since this part of the mechanism is irrelevant to the core invention of the present application, it is not recorded in the present application.

[0068] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
