[0034] Embodiment 1

[0035] See also Figures 1 to 4A linear filling machine for ready-mixed beverage bottle caps, comprising a linear track 1, a feeding channel 3 for conveying an inner tube to the linear track 1, a powder filling device 4 for filling powder into the inner tube, and a clamping plate 6 arranged on one side of the linear track 1 and movable left and right and forward and backward, the powder filling device 4 being arranged on the linear track 1, the outlet of the feeding channel 3 being butted against the inlet of the linear track 1, the feeding channel 3 being used for conveying the inner tube to the linear track 1, the inner tube moving along the linear track 1 and passing through the powder filling device 4 for filling beverage powder, the beverage powder being tea powder, fruit powder, milk tea powder or powder of other flavors, the function of the clamping plate 6 being to drag the inner tube on the linear track 1;

[0036] Specifically, the powder filling device 4 includes a hopper 41 and a plurality of discharge pipes 42, the upper end of the discharge pipe 42 is connected to the bottom of the hopper 41, and the lower end extends to the linear track 1. A quantitative screw or a quantitative valve for controlling the powder output is provided in the discharge pipe 42; the hopper 41 is filled with powder, and the powder is discharged to the inner tube through the discharge pipe 42 connected to the bottom of the hopper 41, and the quantitative screw or the quantitative valve is used to control the powder discharge amount; since a plurality of discharge pipes 42 are provided, a plurality of inner tubes on the linear track 1 can be filled with powder at the same time. In the present embodiment, six discharge pipes 42 are provided, and six inner tubes of the same batch can be filled with powder at the same time. Of course, the number of discharge pipes 42 is not limited to six, and more or less can be provided;

[0037] A plurality of first openings 61 are provided on one side of the positioning plate 6 close to the linear track 1. The number of the first openings 61 is 2 to 8 times the number of the feeding tubes 42. After the positioning plate 6 moves backward to overlap with the linear track 1 so that the inner tube is inserted into the first opening 61, it moves to the right to drive the inner tube to move right along the linear track 1. The first opening 61 is used to plug the inner tube. When the positioning plate 6 moves forward and backward, the inner tube can enter or leave the first opening 61. When the positioning plate 6 moves backward to a position overlapping with the linear track 1, the inner tube enters the first opening 61. When the positioning plate 6 moves forward, the inner tube leaves the first opening 61. The first opening 61 is separated from the locking plate 6; when the locking plate 6 moves left and right at the position overlapping with the linear track 1, the inner tube can move left and right with the locking plate 6; the number of first openings 61 on the locking plate 6 is 2 to 8 times the number of discharge tubes 42 221, and when the locking plate 6 moves right at the position overlapping with the linear track 1, 2 to 8 batches of inner tubes on the linear track 1 can be moved simultaneously, and the multiple here is an integer multiple; in the present embodiment, the number of first openings 61 is 6 times the number of discharge tubes 42 221, that is, the number of first openings 61 is 36.

[0038] It should be noted that the inner tube is a part of the bottle cap of the ready-mixed beverage, the powder is filled in the inner tube, and then the inner tube is sealed with a plug; the forward and backward movement and the left and right movement are relative to the linear track 1, such as Figure 1 and Figure 4As shown, the front side is one side of the positioning plate 6, the rear side is the side of the linear track 1 relative to the positioning plate 6, the entrance end of the linear track 1 is the left side, and the exit end of the linear track 1 is the right side;

[0039] The locking plate 6 is driven by a cylinder or other mechanism to achieve forward and backward movement and left and right movement.

[0040] Working principle:

[0041] The initial position of the locking plate 6 is a position where the left end of the locking plate 6 is closest to the left end of the linear track 1 and the first opening 61 of the locking plate 6 is not inserted into the inner tube;

[0042] First, after the plurality of inner tubes enter the entrance end of the linear track 1, the positioning plate 6 moves backward from the initial position of the positioning plate 6 to the position as shown in FIG. Figure 1 and Figure 2 The position where the positioning plate 6 overlaps with the linear track 1 allows multiple inner tubes to be pushed into the linear track 1 at the same time and the inner tubes enter the first opening 61. In this embodiment, the positioning plate 6 moves backward only after six inner tubes enter the entrance end of the linear track 1. These six inner tubes form a batch.

[0043] Next, the positioning plate 6 moves a fixed distance to the right, dragging all the inner tubes on the linear track 1 to move to the right. The fixed distance can be set according to the number of inner tubes in each batch. If the number of discharge tubes 42 is 6, the number of inner tubes in each batch is 6, and the fixed distance to the right is the distance of 6 first openings 61. When the positioning plate 6 moves to the right by the distance of 6 first openings 61 at a time, multiple inner tubes of the same batch also move to the right by the distance of 6 first openings 61, so that multiple inner tubes of the same batch can be transferred to the bottom of the powder filling device 4 at the same time. Since multiple inner tubes of the same batch also move to the right by the distance of 6 first openings 61, the leftmost position of the linear track 1 is vacant for the inner tubes of the next batch to enter.

[0044] Subsequently, the locking plate 6 first moves forward to separate the inner tube from the locking plate 6, and then moves leftward to return to the initial position of the locking plate 6;

[0045] Then, the locking plate 6 moves backward from the initial position of the locking plate 6 to the position overlapping with the linear track 1, so that the inner tubes of the next batch enter the first opening 61, and the locking plate 6 moves to the right again by a fixed distance, and the inner tubes of the previous batch and the inner tubes of the next batch are dragged to the right by the locking plate 6 at the same time, and this is repeated to achieve continuous linear movement of the inner tubes of the same batch along the linear track 1. When the inner tubes of the same batch arrive under the powder filling device 4, the powder filling device 4 fills powder to multiple inner tubes of the same batch at the same time. When the locking plate 6 moves to the right, the inner tubes of the same batch that have completed powder filling can be moved out at the same time, and the inner tubes of the next batch arrive under the powder filling device 4 at the same time. There is no need to wait for the inner tubes of the multiple ready-mixed beverage bottle caps of the next batch to enter the filling position, thereby achieving continuous and efficient powder filling.

[0046] The positioning plate 6 first moves backward, then moves to the right, then moves forward, and finally moves leftward back to the initial position of the positioning plate 6. The moving route of the positioning plate 6 is rectangular. The positioning plate 6 moves cyclically on the rectangular moving route, so that multiple batches of inner tubes on the linear track 1 can be moved simultaneously, realizing the linear movement of the inner tubes. The short stroke of the positioning plate 6 is conducive to speeding up the powder filling speed, thereby improving the powder filling efficiency of the bottle cap.

[0047] While the positioning plate 6 moves to the right and then returns to its initial position, the feed channel 3 continues to transport the inner tubes to the linear track 1, so that the next batch of inner tubes can enter the linear track 1 and prepare for the next batch delivery, thereby realizing continuous batch feeding, reducing the waiting time for feeding, and helping to improve filling efficiency.

[0048] Preferably, see Figure 1 and Figure 4 , the linear filling machine further comprises a first plugging device 5 for pressing the plug into the inner tube, and the powder filling device 4 and the first plugging device 5 are sequentially arranged on the linear track 1;

[0049] The first plugging device 5 includes a plurality of vacuum suction nozzles 51 that can move up and down and forward and backward, a plug mold 52 arranged on one side of the linear track 1, and a plug channel 53 arranged on one side of the plug mold 52. The plug mold 52 can move left and right, and a plurality of second openings 521 are provided on the side of the plug mold 52 close to the plug channel 53. The plurality of vacuum suction nozzles 51 move downward from the top of the plug mold 52 to overlap with the plurality of second openings 521 and absorb the plugs, then start to move upward, move forward to the top of the linear track 1, move downward to overlap with the inner tube, then start to move upward, and then move backward to the top of the plug mold 52.

[0050] The plug channel 53 is responsible for conveying the plug to the plug mold 52. The initial position of the plug mold 52 is as follows: Figure 4As shown, while the plug mold 52 moves to the right, the plugs enter the multiple second openings 521 of the plug mold 52 one by one from the outlet of the plug channel 53 until all the second openings 521 are loaded with plugs, and then the multiple vacuum suction nozzles 51 start to move downward from the top of the plug mold 52 until they overlap with the multiple second openings 521 and suck up the multiple plugs at the same time, and then the multiple vacuum suction nozzles 51 move forward with the plugs to the top of the linear track 1, and at the same time the plug mold 52 moves to the left to the initial position of the plug mold 52 and then moves to the right again to allow the next batch of plugs to enter the plug mold 52, and then the multiple vacuum suction nozzles 51 move forward again. The plug is pressed into the inner tube on the linear track 1 by moving downward, and the multiple vacuum suction nozzles 51 stop sucking the plug so that the vacuum suction nozzles 51 are separated from the plug. Finally, the multiple vacuum suction nozzles 51 first move upward and then move backward to the top of the plug mold 52. At this time, the vacuum suction nozzle 51 enters the next cycle to ensure continuous plugging. The circulation route of the vacuum suction nozzle 51 is: it moves downward from the top of the plug mold 52 to overlap with the multiple second openings 521 and suck the plug, then starts to move upward, then moves forward to the top of the linear track 1, then moves downward to overlap with the inner tube, then starts to move upward, and then moves backward to the top of the plug mold 52. Among them, the vacuum suction nozzle 51 can be driven by a cylinder or other mechanism to achieve up and down movement and forward and backward movement.

[0051] In the case of setting the first plugging device 5, the number of the first openings 61 on the positioning plate 6 is at least three times the number of the feeding tubes 42, and the positioning plate 6 moves along the following route to improve the efficiency of powder filling and plugging: the positioning plate 6 moves backward from the initial position of the positioning plate 6 to the position as shown in FIG. Figure 1 and Figure 2 The position where the positioning plate 6 overlaps with the linear track 1 allows the inner tube to enter the first opening 61. Figure 3 The position shown is defined as the first position, and then the positioning plate 6 moves a fixed distance to the right to the second position, dragging all the inner tubes on the linear track 1 to move to the right. The fixed distance can be set according to the number of the feeding tubes 42. If the number of the feeding tubes 42 is 6, the fixed distance to the right is the distance of 6 first openings 61. When the positioning plate 6 moves a fixed distance to the right once, a batch of inner tubes arrives below the powder filling device 4, and another batch of inner tubes originally located below the powder filling device 4 is moved to the bottom of the first plugging device 5. Another batch of inner tubes originally located below the first plugging device 5 is moved out, and then the positioning plate 6 moves forward to separate the inner tubes from the positioning plate 6. This position is called the third position, and then the positioning plate 6 moves to the left from the third position back to the initial position of the positioning plate 6. The positioning plate 6 repeatedly moves according to the rectangular route of the initial position-first position-second position-third position-initial position, and can transport the inner tubes along the linear track 1 batch by batch, and can make the inner tubes be filled with powder and plugged batch by batch, and the filling efficiency is high.

[0052] Preferably, the powder filling device 4 also includes a sliding plate 43 that can move up and down. The sliding plate 43 is provided with a plurality of through-tube holes 431. The through-tube holes 431 correspond to the feed tubes 42 one by one, and the middle of the feed tubes 42 passes through the through-tube holes 431. After the powder filling is completed, the sliding plate 43 moves downward until the bottom surface of the sliding plate 43 abuts against the top surface of the inner tube, and then the inner tube moves to the right along the linear track 1. During the movement of the inner tube to the right, the sliding plate 43 can scrape out the powder that exceeds the top surface of the inner tube to avoid affecting the subsequent plugging process. The sliding plate 43 can be driven by a cylinder or other mechanism to move up and down.

[0053] Preferably, the linear filling machine further comprises a second plugging device 8, the powder filling device 4, the first plugging device 5 and the second plugging device 8 are sequentially arranged on the linear track 1, and the second plugging device 8 comprises a pressing plate 81 which can move up and down, and the pressing plate 81 is located above the linear track 1. When the pressing plate 81 moves downward, it can apply pressure to the plug so that the plug is pressed against the inner tube; when the vacuum suction nozzle 51 of the first plugging device 5 carries the plug and moves downward above the inner tube, it can press the plug against the inner tube, and when the pressing plate 81 of the second plugging device 8 moves downward, it pressurizes the plug again to ensure that the plug can be pressed into the inner tube in place. Among them, the pressing plate 81 can be driven by a cylinder or other mechanism to move up and down. Optionally, one or more pressing plates 81 can be provided; when one is provided, the projection area of ​​the pressing plate 81 should be able to cover all the inner tubes of a single batch; when multiple pieces are provided, the pressing plates 81 correspond to the inner tubes one by one. When the second pressing device 8 is set, the number of first openings 61 on the positioning plate 6 is at least 4 times the number of feeding tubes 42, and the positioning plate 6 moves along the following route: the positioning plate 6 moves backward from the initial position of the positioning plate 6 to the first position so that the inner tube enters the first opening 61, and then the positioning plate 6 moves a fixed distance to the right to the second position, dragging all the inner tubes on the linear track 1 to move to the right, and when the positioning plate 6 moves a fixed distance to the right once, a batch of inner tubes arrives under the powder filling device 4, and another batch of inner tubes originally located under the powder filling device 4 is moved to the bottom of the first pressing device 5, and another batch of inner tubes originally located under the first pressing device 5 is moved to the bottom of the second pressing device 8, and another batch of inner tubes originally located under the second pressing device 8 is moved out, and then the positioning plate 6 moves forward to the third position, and then the positioning plate 6 moves left from the third position back to the initial position of the positioning plate 6.

The detection device 9 includes a plurality of height detectors 91 located on one side of the linear track 1 and a plurality of blowing nozzles 92 arranged on the same side of the height detector 91. A defective product discharge port 12 is provided on the side of the linear track 1 opposite to the blowing nozzles 92. The number of height detectors 91 is the same as the number of feed pipes 42, and the number of blowing nozzles 92 is the same as the number of feed pipes 42. Multiple height detectors 91 simultaneously perform height detection on the inner tubes of the same batch to check whether the plug is pressed into the inner tube in place. If the plug on the inner tube is not pressed into place, the blowing nozzle 92 at the corresponding position will be activated, and the unqualified inner tube will be blown out of the defective product discharge port 12. Preferably, a collection box 94 connected to the defective product discharge port 12 is provided on the side of the linear track 1 opposite to the blowing nozzles 92. The collection box 94 is used to collect and store unqualified inner tubes.

[0055] Preferably, the detection device 9 further includes a mounting plate 93 that can be moved up and down, and a plurality of height detectors 91 and a plurality of air blowing nozzles 92 are mounted on the mounting plate 93. By setting the mounting plate 93 that can be moved up and down, the heights of the height detectors 91 and the air blowing nozzles 92 can be adjusted to adapt to the height detection of inner tubes at different heights. The mounting plate 93 can be driven by a cylinder or other mechanism to move up and down.

[0056] Preferably, the outlet of the plug channel 53 is provided with a first gear bar 531 that can move up and down. When all the second openings 521 are equipped with plugs, the first gear bar 531 moves downward to block the plug channel 53 from continuing to push the plug into the second opening 521. After all the second openings 521 are equipped with plugs, the plug channel 53 no longer pushes the plug. Optionally, a counter (not shown in the figure) is set near the outlet position of the plug channel 53, and the number of plugs output by the plug channel 53 is counted by the counter. When the number of output plugs is equal to the number of second openings 521, the controller of the filling machine controls the first gear bar 531 to move downward to block the plug channel 53 from continuing to push the plug into the second opening 521. Optionally, because the initial position of the plug mold 52 is fixed, and all the second openings 521 are empty when the plug mold 52 is in its initial position, a sensor (not shown in the figure) is provided to detect when the plug mold 52 reaches its initial position, thereby triggering the first gear bar 531 to move upward, so that the plug channel 53 can continue to push the plug into the second opening 521. The first gear bar 531 can be driven by a cylinder or other mechanism to move up and down.

[0058] Specifically, the feed die 2 includes a support plate 21 that can move left and right and an inner tube guide plate 22 arranged on the support plate 21. The inner tube guide plate 22 can move forward and backward relative to the support plate 21. A third opening 221 is provided on the side of the inner tube guide plate 22 close to the linear track 1. When the support plate 21 moves to the right, the feed channel 3 pushes the inner tubes into the third openings 221 one by one until all the third openings 221 are equipped with inner tubes, and then the inner tube guide plate 22 moves forward until the inner tube enters the linear track 1 and then starts to move backward; the inner tube guide plate 22 is arranged On the support plate 21, the inner tube guide plate 22 can move left and right with the support plate 21, and the third opening 221 is used to accommodate the inner tube, so that the inner tube can move with the inner tube guide plate 22 when it moves. While the support plate 21 drives the inner tube guide plate 22 to move to the right, the inner tubes enter the multiple third openings 221 of the inner tube guide plate 22 from the outlet of the feed channel 3 one by one until all the third openings 221 are loaded with inner tubes, and then the inner tube guide plate 22 moves forward to push multiple inner tubes into the linear track 1 at the same time and then moves backward to realize batch transportation of the inner tubes. The number of the third openings 221 is the same as the number of the feed tubes 42. In this embodiment, there are 6 feed tubes 42, and 6 third openings 221 are set. A single batch can transport 6 inner tubes. Of course, the number of feed tubes 42 and the third openings 221 is not limited to 6, and more or less can be set.

[0059] The support plate 21 can be driven by a cylinder or other mechanism to move left and right, and the inner tube guide plate 22 can be driven by a cylinder or other mechanism to move forward and backward.

[0060] Working principle:

[0061] The initial position of the feed die 2 is as follows Figure 1 and Figure 2 As shown, at this time, the third opening 221 at the rightmost end of the inner tube guide plate 22 is aligned with the outlet of the feed channel 3, and the initial position of the positioning plate 6 is a position where the left end of the positioning plate 6 is closest to the left end of the linear track 1 and the first opening 61 of the positioning plate 6 is not inserted into the inner tube;

[0062] In the first step, the support plate 21 moves rightward from the initial position of the feed die 2 and drives the inner tube guide plate 22 to move rightward, so that the inner tubes coming out of the feed channel 3 enter the multiple third openings 221 of the inner tube guide plate 22 one by one, until all the third openings 221 are loaded with inner tubes and the six third openings 221 are aligned with the six first openings 61 at the leftmost end of the positioning plate 6;

[0063] In the second step, the inner tube guide plate 22 moves forward and the positioning plate 6 moves backward from the initial position of the positioning plate 6 to the position as shown in FIG. Figure 1 and Figure 2 The position where the positioning plate 6 overlaps with the linear track 1 allows multiple inner tubes to be pushed into the linear track 1 at the same time and the inner tubes enter the first opening 61;

[0064] In the third step, the inner tube guide plate 22 first moves backward and then moves leftward with the support plate 21 to return to the initial position of the feed mold 2. At the same time, the positioning plate 6 moves a fixed distance to the right, dragging all the inner tubes on the linear track 1 to move to the right. The fixed distance can be set according to the number of inner tubes in each batch. If the number of inner tubes in each batch is 6, the fixed distance to the right is the distance of 6 first openings 61. When the positioning plate 6 moves to the right by the distance of 6 first openings 61 at a time, multiple inner tubes of the same batch also move to the right by the distance of 6 first openings 61, so that multiple inner tubes of the same batch can be transferred to the bottom of the powder filling device 4 at the same time. Since multiple inner tubes of the same batch also move to the right by the distance of 6 first openings 61, the leftmost position of the linear track 1 is vacant for the inner tubes of the next batch to enter.

[0065] In the fourth step, the positioning plate 6 first moves forward to separate the inner tube from the positioning plate 6, and then moves to the left to return to the initial position of the positioning plate 6. During the process of the positioning plate 6 moving forward and then to the left, the support plate 21 moves to the right again from the initial position of the feeding die 2 and drives the inner tube guide plate 22 to move to the right, so that the inner tubes coming out of the feeding channel 3 enter the multiple third openings 221 of the inner tube guide plate 22 one by one, until all the third openings 221 are loaded with inner tubes and the six third openings 221 are aligned with the six first openings 61 at the leftmost end of the positioning plate 6, and the multiple inner tubes on the inner tube guide plate 22 are the inner tubes of the next batch;

[0066] In the fifth step, the inner tube guide plate 22 moves forward again and the positioning plate 6 moves backward from the initial position of the positioning plate 6 to a position overlapping with the linear track 1, so that the next batch of inner tubes are simultaneously pushed into the linear track 1 and the inner tubes enter the first opening 61;

[0067] In the sixth step, the inner tube guide plate 22 moves backward again and then moves leftward with the supporting plate 21 to return to the initial position of the feeding mold 2. At the same time, the locking plate 6 moves to the right by a fixed distance. The inner tubes of the previous batch and the inner tubes of the next batch are dragged to the right by the locking plate 6 at the same time. The fourth to sixth steps are repeated in this way to realize the continuous linear movement of the inner tubes of the same batch along the linear track 1. When the inner tubes of the same batch arrive under the powder filling device 4, the powder filling device 4 fills powder to multiple inner tubes of the same batch at the same time. When the locking plate 6 moves to the right, the inner tubes of the same batch that have completed the powder filling can be moved out at the same time. At the same time, the inner tubes of the next batch arrive under the powder filling device 4. There is no need to wait for the inner tubes of the multiple ready-mixed beverage bottle caps of the next batch to enter the filling position, thereby realizing continuous and efficient powder filling.

[0068] Preferably, see Figure 2, a feed port 11 is provided on the side of the inlet end of the linear track 1 close to the feed die 2, and a baffle 7 that can move up and down is provided above the feed port 11. When the inner tube guide plate 22 moves forward, the baffle 7 moves downward. When the bottom surface of the baffle 7 is lower than the top surface of the inner tube, the inner tube guide plate 22 moves backward to prevent the inner tube from moving backward with the inner tube guide plate 22. The setting of the feed port 11 facilitates the inner tube to enter the linear track 1. The function of the baffle 7 is to prevent the inner tube from moving backward with the inner tube guide plate 22 when moving backward, and ensure that the inner tube can stay in the linear track 1; when the baffle 7 moves downward until its bottom surface is lower than the top surface of the inner tube, when the inner tube guide plate 22 moves backward, the inner tube is blocked by the baffle 7 and will not move backward with the inner tube guide plate 22, and stay in the linear track 1; before the inner tube guide plate 22 moves forward, the baffle 7 should move upward so that the inner tube has enough space to enter the linear track 1.

[0069] If the feed port 11 is not provided, the inner tube guide plate 22 can be provided on a horizontal plane higher than the linear track 1, so that the inner tube falls into the linear track 1 when the inner tube guide plate 22 moves forward, but the inner tube may be damaged when falling, affecting the quality of the bottle cap, or the inner tube may tilt after falling and affect the filling efficiency; if the feed port 11 is provided, the inner tube guide plate 22 can be provided on a horizontal plane where the feed port 11 is located, so that the inner tube is pushed horizontally into the linear track 1 when the inner tube guide plate 22 moves forward, and the inner tube always enters the linear track 1 at the same height, which can reduce damage to the inner tube and avoid tilting of the inner tube.

[0070] Preferably, see Figure 1 , the outlet of the feed channel 3 is provided with a second gear bar 31 that can move up and down. When all the third openings 221 are equipped with inner tubes, the second gear bar 31 moves downward to block the feed channel 3 from continuing to push the inner tube into the third opening 221. After all the third openings 221 are equipped with inner tubes, the feed channel 3 no longer pushes the inner tube. Optionally, a counter (not shown in the figure) is set near the outlet position of the feed channel 3, and the number of inner tubes output by the feed channel 3 is counted by the counter. When the number of output inner tubes is equal to the number of third openings 221, the controller of the filling machine (not shown in the figure) controls the second gear bar 31 to move downward to block the feed channel 3 from continuing to push the inner tube into the third opening 221. Optionally, because the initial position of the feed die 2 is fixed, and all the third openings 221 are empty when the feed die 2 is in its initial position, a sensor (not shown in the figure) is set to trigger the second gear bar 31 to move upward, so that the feed channel 3 can continue to push the inner tube into the third opening 221. The second gear bar 31 can be driven by a cylinder or other mechanism to move up and down.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
