[0016] Furthermore, a filling method of a novel filling machine comprises the following steps:

[0017] Step (1), placing the filling bottle of the product to be filled on the first conveyor belt by a robot; the first drive motor works to provide power to the first conveyor belt; the first conveyor belt conveys the filling bottle through the interception and positioning device, and the interception and positioning device is about to intercept and position the filling bottle;

[0018] In step (2), the electric eye arranged in the interception and positioning device detects the number of filled bottles conveyed on the first conveyor belt. When the number of filled bottles reaches the number of one filling process, the first interception knife cylinder works, driving the first interception knife to extend into the top of the first conveyor belt to intercept the filled bottles in front of the conveying; at the same time, the second interception knife cylinder works, driving the second interception knife to extend into the top of the first conveyor belt to intercept the filled bottles in the rear of the conveying; the interval formed by the first interception knife 34 and the second interception knife accurately positions a plurality of filled bottles directly below the filling device; at this time, the first drive motor is powered off and stops working, and the first conveyor belt stops conveying the filled bottles; in step (3), the lifting cylinder arranged in the filling lifting assembly starts working, pushing the lifting cylinder push plate to descend along the lifting guide shaft, thereby driving the clamping assembly to synchronously descend to the bottle mouth close to the filled bottle, and the lifting cylinder stops working; the first clamping cylinder and the second clamping cylinder both start working, respectively pushing the first clamping plate and the second clamping plate to move in opposite directions, at this time, the first clamping cylinder and the second clamping cylinder The cylinder needs to synchronously overcome the tension of the stretching spring, so that the first clamp and the second clamp are respectively driven by the first clamping plate and the second clamping plate, and then respectively move in opposite directions along the weighing platform guide rail through the first weighing platform slider and the second weighing platform slider, and the first clamp and the second clamp are separated from each other, and the clamping space is opened to facilitate clamping the filling bottle; after the first clamp and the second clamp continue to descend to the lower part of the bottle mouth of the filling bottle, the lifting cylinder stops working, and the first clamp and the second clamp stop descending. At the same time, the first clamping cylinder and the second clamping cylinder both stop working, and the first clamp and the second clamp are respectively moved toward each other along the weighing platform guide rail through the first weighing platform slider and the second weighing platform slider under the tension of the stretching spring, and the first clamp and the second clamp are close to each other, and the first clamp and the second clamp cooperate with each other to clamp the filling bottle; the lifting cylinder works, pulling the lifting cylinder push plate to rise along the lifting guide shaft, thereby driving the clamping assembly to rise synchronously, and when the bottle mouth of the filling bottle clamped by the first clamp and the second clamp extends into the filling nozzle, the filling nozzle begins to fill the filling bottle with product;

[0019] Step (4), the filling bottle continues to rise with the first chuck and the second chuck driven by the lifting cylinder push plate, and the filling nozzle is connected to the filling product through the filling machine valve, pipeline and diverter box; at the same time, the translation cylinder set in the translation assembly works to push the sliding main board to move in the direction close to the second conveyor belt, and the filling bottle clamped by the first chuck and the second chuck moves with the sliding main board, and the filling nozzle performs the first stage of filling the filling bottle. When the first stage of filling of the filling bottle by the filling nozzle is about to reach the set standard filling volume, the weighing sensor detects the total weight value of the filling bottle and the filling product, and sends a signal to the filling nozzle, and the filling nozzle is filled by the first stage. The first-stage filling turns into the second-stage filling, and the filling nozzle is about to perform the second-stage filling on the filling bottle; step (5), when the filling bottle moves to the top of the second conveyor belt, the translation cylinder stops working and the sliding main board stops moving; the lifting cylinder starts working, pushing the lifting cylinder push plate down along the lifting guide shaft, thereby driving the clamping assembly to descend synchronously, and before the bottom of the filling bottle clamped by the first clamp and the second clamp contacts the second conveyor belt, the lifting cylinder stops working. At this time, the filling nozzle is about to perform the second-stage filling on the filling bottle, and the weighing sensor detects whether the total weight value of the filling bottle and the filling product reaches the set weight value , and feeds back the detected value to the filling nozzle, which replenishes the filling bottle to the specified weight. After the replenishment is completed, the filling of the filling bottle is stopped, which avoids the error caused by the moving acceleration of the filling bottle to the detection data of the weighing sensor when it is transferred. When the bottom of the filling bottle contacts the second conveyor belt, the first clamping cylinder and the second clamping cylinder both start to work, respectively pushing the first clamping plate and the second clamping plate to move in the opposite direction, and the first clamping cylinder and the second clamping cylinder overcome the tension of the stretching spring, so that the first clamp and the second clamp are respectively driven by the first clamping plate and the second clamping plate, and then respectively pass through the first weighing platform slide block and the second weighing platform slide block along the weighing platform The table guide rail moves in the opposite direction, the first clamp and the second clamp move away from each other, and the first clamp and the second clamp release the clamping of the filling bottle. Then, the lifting cylinder works to pull the lifting cylinder push plate to rise along the lifting guide shaft, thereby driving the clamping assembly to rise synchronously. When the clamping assembly rises to the initial position, the lifting cylinder stops working, and then the second drive motor works to provide power to the second conveyor belt, and the second conveyor belt transports the filled bottles of the product to the production station; at the same time, the translation cylinder works to push the sliding main board to move away from the second conveyor belt. After resetting to the initial position, the translation cylinder stops working; the filling work is completed;

[0020] Step (6), looping step (1) to step (5), and batch filling the filling bottles of the product to be filled.

[0021] Beneficial effects of the present invention:

[0022] The invention realizes automatic filling of filling bottles by setting a filling device, an interception positioning device and a conveying device to work together. The advantages of the invention are:

[0023] 1) The translation component can realize the position change of the filling component, the clamping component and the filling lifting component, and realize the function of transferring the filling bottle. The filling component, the clamping component, the translation component and the filling lifting component cooperate with each other to further improve the filling efficiency. The filling lifting component realizes the lifting and lowering movement of the clamping component. The filling bottle is filled during the transfer process of the translation component. The filling nozzle adopts the filling mode of the first stage filling and the second stage filling to further improve the filling efficiency. The filling bottles that have completed the filling at the same time are transferred to the second conveyor belt through the translation component, which makes full use of the time difference in production, greatly improves the filling efficiency, reduces the production cost, and has good economic benefits.

[0024] 2) Before the bottom of the filling bottle clamped by the first chuck and the second chuck contacts the second conveyor belt, the lifting cylinder stops working. At this time, the weighing sensor detects whether the total weight value of the filling bottle and the filling product reaches the set weight value, and feeds back the detection value to the filling nozzle. The filling nozzle replenishes the filling bottle to the specified weight, and stops filling the filling bottle after the replenishment is completed, thereby avoiding the movement acceleration of the filling bottle during transfer causing errors in the detection data of the weighing sensor; the first chuck and the second chuck use the tension of the tension spring as the clamping force for clamping the filling bottle. Since the tension of the tension spring is relatively stable, the first chuck and the second chuck have good stability when clamping the filling bottle, and the external force applied by the cylinder to the weighing sensor is small, which improves the detection accuracy of the weighing sensor, so that the filling amount of each filling bottle basically reaches the specified filling amount, thereby improving the filling quality.

[0025] 3) The installation position of the limit block of the weighing platform on the adjustment plate can be adjusted, thereby adjusting the clamping position of the first chuck and the second chuck to adapt to clamping filling bottles of different sizes; by adjusting the locking position of the filling nozzle adjustment pad sleeve and the filling nozzle locking block on the first movable bracket and the second movable bracket, the installation spacing of the filling nozzle can be adjusted to adapt the filling nozzle to filling bottles of different sizes; the filling nozzle has a wide filling application range.

[0026] 4) By adjusting the installation position of the intercepting knife main seat on the intercepting knife fixing seat, the installation height of the first intercepting knife and the second intercepting knife on the intercepting knife fixing seat can be adjusted to adapt to the first intercepting knife and the second intercepting knife to intercept filling bottles of different heights; by adjusting the installation positions of the first clamping block and the second clamping block on the first horizontal axis and the second horizontal axis respectively, the installation interval of the first intercepting knife and the second intercepting knife on the first horizontal axis and the second horizontal axis can be adjusted to adapt to the interception of filling bottles of different diameters.

[0027] 5) By rotating the back wave hand wheel clockwise or counterclockwise, the trapezoidal nut can be raised or lowered on the adjusting screw, which further drives the lifting bottom plate to rise or fall, so that the entire filling device can be raised or lowered to adapt to the filling bottles of different heights for filling. The filling device has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

The filling nozzle 214 adopts a filling mode of first-stage filling and second-stage filling to further improve the filling efficiency, and then the filling bottles 8 that have completed filling at the same time are transferred to the second conveyor belt 42 through the translation assembly 23, which makes full use of the time difference of production, greatly improves the filling efficiency, reduces the production cost, and has good economic benefits.

[0046] Specifically, in this embodiment, the clamping assembly 22 includes a first clamping cylinder 221, a second clamping cylinder 222, a first clamping plate 223, a second clamping plate 224, a first clamping head 225 and a second clamping head 226; the first clamping cylinder 222 and the second clamping cylinder 222 are extended outwardly through the first clamping cylinder fixing plate 227 and are symmetrically installed on the left and right ends of the lifting cylinder push plate 241, and the piston rod of the first clamping cylinder 221 and the piston rod of the second clamping cylinder 222 are set apart; the piston rod of the first clamping cylinder 221 is fixed by the second clamping cylinder The fixed plate 228 is connected to the first clamping plate 223; the piston rod of the second clamping cylinder 222 is connected to the second clamping plate 224 through the second clamping cylinder fixed plate 228; the first clamping plate 223 and the second clamping plate 224 are connected through the clamping guide shaft 229 and the clamping linear bearing 2210; a plurality of first clamps 225 are arranged on the first clamping plate 223; a plurality of second clamps 226 are arranged on the second clamping plate 224; each first clamp 225 and each second clamp 226 cooperate with each other to clamp the filling bottle 8.

The first conveyor belt 41 was responsible for conveying the filling bottles 8 to be filled; the second conveyor belt 42 was responsible for conveying the filling bottles 8 that had been filled with products; the first conveyor belt 41 and the second conveyor belt 42 were set to facilitate the orderly filling of the filling bottles 8, further improving the filling efficiency.

[0055] Specifically, in the present embodiment, a gas storage tank assembly 5 is further provided at the bottom of the rack 1 ; a shunt box 6 is provided at the top of the rack 1 ; and a control electric box 7 is provided at the side of the rack 1 .

[0056] Specifically, in the present embodiment, a filling method of a new filling machine includes the following steps: step (1), placing a filling bottle 8 of a product to be filled on a first conveyor belt 41 by a manipulator; the first drive motor 45 operates to provide power to the first conveyor belt 41; the first conveyor belt 41 conveys the filling bottle 8 through the interception and positioning device 3, and the interception and positioning device 3 is about to intercept and position the filling bottle 8;

[0057] Step (2), the electric eye 311 provided in the interception and positioning device 3 detects the number of filled bottles 8 conveyed on the first conveyor belt 41. When the number of filled bottles 8 reaches the number for one filling process, the first interception knife cylinder 36 works to drive the first interception knife to extend above the first conveyor belt 41 to intercept the filled bottles 8 at the front of the conveying; at the same time, the second interception knife cylinder 37 works to drive the second interception knife 35 to extend above the first conveyor belt 41 to intercept the filled bottles 8 at the rear of the conveying; the interval formed by the first interception knife and the second interception knife 35 accurately positions the multiple filled bottles 8 directly below the filling device 2; at this time, the first drive motor 45 is powered off and stops working, and the first conveyor belt 41 stops conveying the filled bottles 8;

[0058] In step (3), the lifting cylinder 243 provided in the filling lifting assembly 24 starts to work, pushing the lifting cylinder push plate 241 to descend along the lifting guide shaft 242, thereby driving the clamping assembly 22 to synchronously descend to the bottle mouth close to the filling bottle 8, and the lifting cylinder 243 stops working; the first clamping cylinder 221 and the second clamping cylinder 222 both start to work, respectively pushing the first clamping plate 223 and the second clamping plate 224 to move in the opposite direction. At this time, the first clamping cylinder 221 and the second clamping cylinder 222 need to synchronously overcome the tension of the tension spring 2217, so that the first clamping head 225 and the second clamping head 226 are respectively driven by the first clamping plate 223 and the second clamping plate 224, and then respectively move in the opposite direction along the weighing platform guide rail 2214 through the first weighing platform slider 2215 and the second weighing platform slider 2216, and the first clamping head 225 and the second clamping head 226 are separated from each other, opening the clamping space, which is convenient for clamping the filling bottle 8; the first clamping head 22 After the first and second clamping heads 225 and 226 continue to descend to the lower part of the bottle mouth of the filling bottle 8, the lifting cylinder 243 stops working, the first clamping head 225 and the second clamping head 226 stop descending, and at the same time, the first clamping cylinder 221 and the second clamping cylinder 222 stop working. Under the tension of the tension spring 2217, the first clamping head 225 and the second clamping head 226 move toward each other along the weighing platform guide rail 2214 through the first weighing platform slide block 2215 and the second weighing platform slide block 2216 respectively. The first clamp 225 and the second clamp 226 move closer to each other, and the first clamp 225 and the second clamp 226 cooperate with each other to clamp the filling bottle 8; the lifting cylinder 243 works, pulling the lifting cylinder push plate 241 to rise along the lifting guide shaft 242, thereby driving the clamping assembly 22 to rise synchronously, and when the bottle mouth of the filling bottle 8 clamped by the first clamp 225 and the second clamp 226 extends into the filling nozzle 214, the filling nozzle 214 starts to fill the filling bottle 8 with product;

[0059] Step (4), the filling bottle 8 continues to rise with the first clamp 225 and the second clamp 226 driven by the lifting cylinder push plate 241, and the filling nozzle 214 is connected to the filling product through the filling machine valve 213, the pipeline and the diverter box; at the same time, the translation cylinder 235 provided in the translation assembly 23 works to push the sliding main board 232 to move toward the second conveyor belt 42, and the filling bottle 8 clamped by the first clamp 225 and the second clamp 226 moves with the sliding main board 232, and the filling nozzle 214 performs the first stage of filling on the filling bottle 8. When the first stage filling of the filling bottle 8 by 214 is about to reach the set standard filling volume, the weighing sensor 2211 detects the total weight value of the filling bottle 8 and the filling product, and sends a signal to the filling nozzle 214, and the filling nozzle 214 switches from the first stage filling to the second stage filling, and the filling nozzle 214 is about to perform the second stage filling of the filling bottle 8; it should be noted that the first stage filling is fast filling, and the filling nozzle 214 quickly fills the product into the filling bottle 8, which can make the filling volume of the filling bottle 8 reach 90% of the specified filling volume in a short time. The second stage filling is slow filling, and the filling nozzle 214 slowly fills the product into the filling bottle 8 to the set standard filling volume, which can reduce the bubbles generated during the filling process; further improve the filling quality, the filling nozzle 214 adopts the filling mode of the first stage filling combined with the second stage filling to further improve the filling efficiency, reduce the production cost, and have good economic benefits.

[0060] Step (5), when the filling bottle 8 moves to the top of the second conveyor belt 42, the translation cylinder 235 stops working and the sliding main board 232 stops moving; the lifting cylinder 243 starts working, pushing the lifting cylinder push plate 241 down along the lifting guide shaft 242, thereby driving the clamping assembly 22 to descend synchronously. Before the bottom of the filling bottle 8 clamped by the first clamp 225 and the second clamp 226 contacts the second conveyor belt 42, the lifting cylinder 243 stops working. At this time, the filling nozzle 214 is about to perform the second stage of filling on the filling bottle 8, and the weighing sensor 22 11 detects whether the total weight of the filling bottle 8 and the filling product reaches the set weight value, and feeds back the detection value to the filling nozzle 214. The filling nozzle 214 replenishes the filling bottle 8 to the specified weight. After the replenishment is completed, the filling of the filling bottle 8 is stopped, thereby avoiding the movement acceleration of the filling bottle 8 during the transfer to cause errors in the detection data of the weighing sensor 2211; when the bottom of the filling bottle 8 contacts the second conveyor belt 42, the first clamping cylinder 221 and the second clamping cylinder 222 both start to work, respectively pushing the first clamping plate 223 and the second clamping plate 224 moves in the opposite direction, the first clamping cylinder 221 and the second clamping cylinder 222 overcome the pulling force of the tension spring 2217, so that the first clamp 225 and the second clamp 226 are respectively driven by the first clamping plate 223 and the second clamping plate 224, and then respectively move in the opposite direction along the weighing platform guide rail 2214 through the first weighing platform slider 2215 and the second weighing platform slider 2216, the first clamp 225 and the second clamp 226 are separated from each other, and the first clamp 225 and the second clamp 226 release the clamping of the filling bottle 8, then the lifting cylinder 243 works to pull The lifting cylinder push plate 241 rises along the lifting guide shaft 242, thereby driving the clamping assembly 22 to rise synchronously. When the clamping assembly 22 rises to the initial position, the lifting cylinder 243 stops working, and then the second drive motor 46 works to provide power to the second conveyor belt 42, and the second conveyor belt 42 conveys the filled bottles 8 to the production station; at the same time, the translation cylinder 235 works to push the sliding main board 232 to move away from the second conveyor belt 42. After resetting to the initial position, the translation cylinder 235 stops working; the filling work is completed;

[0061] Step (6), looping steps (1) to (5), and batch filling the filling bottles 8 of the product to be filled.
