[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] like Figure 1 As shown, a liquid filling processing equipment includes a base 1, and liquid filling is completed in a device above the base 1. The base 1 is fixedly connected to the ground, thereby achieving fixation of the filling processing equipment.

[0034] A rotating disk assembly 2 is installed above the base 1. The rotating disk assembly 2 includes a rotating disk 21. A main shaft 4 is fixedly installed at the center of the rotating disk 21. The main shaft 4 passes through the rotating disk 21 and is rotatably connected to the base 1. When the main shaft 4 rotates, the rotating disk 21 can be driven to rotate. The bottle body is placed on the rotating disk 21 and rotates synchronously with the rotating disk 21, thereby completing a series of actions such as filling;

[0035] A first gear 41 is fixedly mounted on the main shaft 2, and the first gear 41 is located below the rotating disk 21. A first driving device 6 is fixedly mounted on the upper end surface of the base 1, and a toothless gear 61 is fixedly mounted on the driving shaft of the first driving device 6. When the toothless gear 61 rotates one circle, it will mesh with the first gear 41; when the first driving device 6 drives the toothless gear 61 to rotate continuously, the main shaft 4 can be made to rotate intermittently, thereby realizing the intermittent rotation of the rotating disk 21. During the time when the rotating disk 21 stops rotating, the filling of the bottle body on the rotating disk 21 is completed, and the bottle body is filled in a stationary state, which ensures the stability of the filling action and avoids leakage and waste of liquid.

[0036] like Figure 3 As shown, a plurality of positioning grooves 211 are provided on the rotating disk 21, and the positioning grooves 211 are evenly distributed in the circumferential direction on the rotating disk 21. In this embodiment, when the first driving device 6 drives the toothless gear 61 to rotate one circle, the rotating angle of the rotating disk 21 is just the central angle corresponding to two adjacent positioning grooves 211, thereby improving the stability of the filling process;

[0037] The bottom of the positioning groove 211 is provided with a step 214, and the inner wall of the positioning groove 211 is provided with a guide groove 215, which is distributed in a vertical direction. The upper end of the step 214 is provided with a lifting plate 24, and the outer circle of the lifting plate 24 cooperates with the positioning groove 211. Figure 4 As shown, a protrusion 241 is provided on the outer circle of the lifting plate 24. When the lifting plate 24 is installed in the positioning groove 211, the protrusion 241 cooperates with the guide groove 215 to realize the sliding connection between the lifting plate 24 and the rotating plate 21. The lifting plate 24 can slide in the positioning groove 211 along the guide groove 215; when the lifting plate 24 is not subjected to other external forces, the lifting plate 24 is attached to the upper end surface of the step 214 under the action of gravity; when the bottle body enters the rotating plate 21, the lower end surface of the bottle body contacts the upper end surface of the lifting plate 24.

[0038] like Figure 3 As shown, a first sliding groove 212 is respectively disposed on both sides of each positioning groove 211. Figure 2As shown, a slider 22 is installed on each first slide groove 212, and a boss 221 is provided on the lower end surface of the slider 22. The boss 221 cooperates with the first slide groove 212 to realize the sliding connection between the slider 22 and the rotating disk 21, so that the slider 22 can slide on the upper end surface of the rotating disk 21 along the first slide groove 212;

[0039] like Figure 5 As shown, a straight tooth 222 is provided on one side of the slider 22, and a second gear 23 is installed on one side of the slider 22. The second gear 23 meshes with the straight tooth 222 on the slider 22. A second driving device 27 is fixedly installed on the lower end of the second gear 23. The second driving device 27 is fixedly installed on the upper end of the rotating disk 21. The second driving device 27 drives the second gear 23 to rotate, thereby driving the slider 22 to slide on the rotating disk 21 along the first slide groove 212;

[0040] When the slider 22 slides along the first slide groove 212 into the positioning groove 211, the slider 22 can limit the bottle body on the upper end of the lifting plate 24 to prevent the bottle body from being thrown out of the rotating disk 21 when the rotating disk 21 rotates, thereby affecting the filling efficiency.

[0041] like Figure 3 As shown, a second slide groove 213 is provided on the rotating disk 21, and the number of the second slide grooves 213 is consistent with the number of the positioning grooves 211. The direction of the second slide groove 213 is from the center of the rotating disk 21 to the center of the positioning groove 211. A push plate 25 is installed in each second slide groove 213, and the boss arranged at the lower end of the push plate 25 cooperates with the second slide groove 213 to realize the sliding connection between the push plate 25 and the rotating disk 21, so that the push plate 25 can slide on the rotating disk 21 along the second slide groove 213; a push cylinder 26 is installed at one end of the push plate 25 facing away from the positioning groove 211, and the push cylinder 26 is fixedly installed at the upper end of the rotating disk 21, and the push cylinder 26 is used to drive the push plate 25 to slide along the second slide groove 213;

[0042] When the push plate 25 approaches the bottle body and contacts the surface of the bottle body, and the slider 22 moves into the positioning groove 211 and limits the bottle body, the bottle body can be closely pressed against the slider 22 under the thrust of the push plate 25, so that the position of the bottle body is kept consistent, the filling stability is improved, and the waste caused by leakage of liquid during the filling process is reduced;

[0043] When the push plate 25 approaches the bottle body and contacts the surface of the bottle body, and the slider 22 has not moved into the positioning groove 211, the push plate 25 can push the bottle body to the rotating disk 21. In this embodiment, the push plate 25 can push the filled bottle body out of the rotating disk 21 and then transmit it to the subsequent process such as screwing the cap.

[0044] like Figure 1As shown, a feeding channel 3 is provided on one side of the rotating disk 21, and the bottle body is transmitted from the feeding channel 3 to the positioning groove 211 on the rotating disk 21, thereby completing the subsequent filling action;

[0045] The feed channel 3 is fixedly mounted on the upper end of the base 1. Figure 6 As shown, a first mounting groove 31 is provided on one side of the upper end of the feed channel 3, a second mounting groove 32 is provided on the inner bottom surface of the feed channel 3, and a limit block 33 that can be raised and lowered is installed in the second mounting groove 32. When the limit block 33 rises and exceeds the inner bottom surface of the feed channel 3, the bottle body can be prevented from entering the rotating disk 21. In this embodiment, when the bottle body after filling is not pushed out of the rotating disk 21, the bottle body 21 rotates to the corresponding position of the feed channel 3 again with the rotating disk 21. At this time, the sensor senses that there is a bottle body in the positioning groove 21, and will control the limit block 33 to rise, thereby preventing the empty bottle body from entering the rotating disk 21.

[0046] like Figure 1 As shown, a blocking mechanism 7 is installed on the outer side of the feed channel 3, and the blocking mechanism 7 blocks and releases the bottle body in the feed channel 3 through the first mounting groove 31, so as to prevent the bottle body from being transferred from the feed channel 3 to the rotating disk 21 when the rotating disk 21 rotates, so that the bottle body cannot fall into the positioning groove 211, causing chaos in the operation of the filling machine and affecting the filling efficiency;

[0047] like Figure 7 As shown, the blocking mechanism 7 includes a rotating rod 71, which is rotatably connected to the base 1, and a belt 72 is connected between the rotating rod 71 and the driving shaft of the first driving device 6, and the belt 72 transmits the rotation of the first driving device 6 to the rotating rod 71;

[0048] A cam 73 is disposed at the upper end of the rotating rod 71, and a baffle 74 is installed between the cam 73 and the feeding channel 3. One end of the baffle 74 contacts the outer circle of the cam 73, and the other end is located in the first mounting groove 31 of the feeding channel 3 and is slidably connected with the feeding channel 3. When the baffle 74 passes through the first mounting groove 31 and enters the inside of the feeding channel 3, the baffle 74 can block the bottle from entering the rotating disk 21.

[0049] A spring 75 is provided between the feed channel 3 and the baffle 74, one end of the spring 75 is fixedly connected to the side of the feed channel 3, and the other end is fixedly connected to the baffle 74;

[0050] In this embodiment, the relationship between the motion states of the baffle 74 and the rotating disk 21 is as follows:

[0051] When the toothless gear 61 is meshed with the first gear 41, the toothless gear 61 rotates to drive the rotating disk 21 to rotate. During the period of meshing and transmission between the toothless gear 61 and the first gear 41, the baffle 74 passes through the first mounting groove 31 and enters the feeding channel 3 under the joint action of the spring 75 and the cam 73, and prevents the bottle from entering the rotating disk 21.

[0052] When the toothless gear 61 is not meshed with the first gear 41, the rotation of the toothless gear 61 will not drive the rotating disk 21 to rotate. During the period when the rotating disk 21 stops rotating, the baffle 74 will allow a bottle to enter the positioning groove 211 on the rotating disk 21.

[0053] The blocking mechanism 7 realizes the above-mentioned movement relationship, ensures the stability of liquid filling and improves the production rhythm.

[0054] like Figure 1 As shown, two filling mechanisms 5 are installed on the outer side of the rotating disk 21, and the two filling mechanisms 5 respectively fill the bottles in the two positioning grooves 211 on the rotating disk 21. The bottle first passes through one of the filling mechanisms 5 to be filled with a portion of liquid, and then rotates to the other filling mechanism 5 to fill the bottle. Compared with setting one filling mechanism 5, setting two filling mechanisms 5 can reduce the filling speed while ensuring the same production efficiency, thereby reducing the foam in the bottle caused by the excessively fast filling speed, which further affects the actual filling amount of the liquid in the bottle.

[0055] like Fig. 9 As shown, the filling mechanism 5 includes a support frame 51, which is fixed to the upper end of the base 1. A liquid storage tank 52 is provided at the upper end of the support frame 51, and a filling head 53 is provided at the lower end of the liquid storage tank 52. In this embodiment, a sensor is provided on the filling head 53 for sensing the liquid level in the bottle body 1, thereby controlling the filling amount of the filling head 53, thereby improving the filling accuracy.

[0056] like Figure 1 As shown, a discharge channel 9 is provided on one side of the rotating disk 21, and the discharge channel 9 is used to transfer the bottles pushed out of the rotating disk 21 to the next process;

[0057] like Figure 1As shown, a lifting mechanism 8 is arranged below the rotating disk 2, and the lifting mechanism 8 includes a lifting cylinder 81, which is fixedly mounted on the upper end of the base 1, and a weighing plate 82 is mounted on the driving shaft of the lifting cylinder 81. When the lifting cylinder 81 controls the weighing plate 82 to rise, and lifts the lifting disk 24, the weighing of the bottle body is completed. When the weighing data is qualified, the slider 22 leaves the positioning groove 211 and will not block the movement of the bottle body. The push plate 25, driven by the pushing cylinder 26, pushes the bottle body out of the rotating disk 21 and into the discharge channel 9; when the weighing data is unqualified, the slider 22 is located in the positioning groove 211, and the bottle body is fixed in the positioning groove 211 under the thrust of the push plate 25. Next, the bottle body will follow the rotating disk 21 to move to the filling mechanism 5 again for secondary filling to make it qualified, thereby increasing the stability and qualified rate of the filling process.

[0058] Working principle:

[0059] By arranging a push plate 25 and a slider 22 on the rotating disk 21, the bottle body can be clamped and fixed to ensure stable filling; by arranging a blocking mechanism 7 on the outer side of the feeding channel 3, the timing of bottle feeding can be controlled, thereby ensuring the stable filling process; by arranging a toothless gear 61 under the rotating disk 21, the intermittent rotation of the rotating disk 21 can be achieved, so that the bottle body remains stationary during liquid filling, thereby ensuring the stability of filling; by arranging two filling mechanisms 5, two-part filling of the liquid in the bottle body can be achieved, while ensuring the filling speed, reducing the generation of foam and improving the accuracy of the filling liquid level; by arranging a lifting mechanism 8 under the rotating disk 21, the bottle body after filling can be weighed, the filling amount can be detected, the outflow of defective products can be avoided, and the qualified rate can be ensured.

[0060] The above shows and describes the basic principles, main features and advantages of the present disclosure. Those skilled in the art should understand that the present disclosure is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present disclosure. Without departing from the spirit and scope of the present disclosure, the present disclosure may have various changes and improvements, and these changes and improvements all fall within the scope of the present disclosure to be protected.
