Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0022] As shown in the figure, a liquid box-in-bag filling machine includes a frame 1. A workbench plate 2 is arranged on the frame 1. A guiding column 3 is arranged on the frame 1 on one side of the workbench plate 2, and a bag clamping seat 4 is arranged above the workbench plate 2. A semi-circular bag clamping groove 41 is formed on the bag clamping seat 4. A claw seat plate 5 is sleeved on the guiding column 3 above the bag clamping seat 4. A lid clamping assembly 6 and a filling assembly 7 are arranged on the claw seat plate 5. An operating assembly 8 is arranged on the guiding column 3. The operating assembly 8 can drive the claw seat plate 5 to rotate and slide on the guiding column 3, so that the lid clamping assembly 6 and the filling assembly 7 are aligned with the bag clamping groove 41 in sequence.

[0023] Specifically, the lid clamping assembly 6 includes a lid clamping seat 61 and a lid clamping piece 62. The lid clamping seat 61 is cylindrical and fixedly connected to the lower surface of the claw seat plate 5. A plurality of the lid clamping pieces 62 are slidably arranged on the lid clamping seat 61 along the radial direction of the lid clamping seat 61 and are annularly arranged around the axis of the lid clamping seat 61. A tightening spring 63 that tightly abuts against the lid clamping piece 62 is arranged on the lid clamping seat 61, so that the lid clamping piece 62 has a tendency to slide inward on the lid clamping seat 61. A lid clamping groove 621 that matches the edge of the butterfly valve of the box-in-bag is formed on the inner side surface of the lower end of the lid clamping piece 62.

[0024] Specifically, the filling assembly 7 includes a material cylinder 71 and a filling air cylinder 72. The material cylinder 71 is fixedly connected to the lower surface of the claw seat plate 5. The filling air cylinder 72 is fixedly arranged on the upper surface of the claw seat plate 5, and the output shaft of the filling air cylinder 72 extends into the material cylinder 71 and is fixedly connected with a pushing plate. A centrifugal pump 73 is arranged on the frame 1. The output port of the centrifugal pump 73 is connected to the feed port of the material cylinder 71 through a material pipe, and the input port of the centrifugal pump 73 is connected to the storage container through a material pipe.

[0025] Specifically, the operation assembly 8 includes a rotating block 81, a handle 82, a connecting rod 83, and a return spring 84. The rotating block 81 is rotatably arranged on the guide post 3. The handle 82 is pivotally connected to the rotating block 81 so as to be longitudinally swingable. One end of the connecting rod 83 is hinged to the handle 82, and the other end is hinged to the claw seat plate 5. One end of the return spring 84 is connected to the guide post 3, and the other end is connected to the handle 82.

[0026] In the above embodiments, the bag-in-box to be filled is placed on the workbench plate 2, and the faucet of the bag-in-box is snapped into the bag slot 41 so that the butterfly valve of the bag-in-box is located above the bag seat 4. Then, the handle 82 is horizontally swung. The handle 82 drives the claw seat plate 5 through the connecting rod 83, and drives the lid clamping assembly 6 to rotate above the bag slot 41 and align with the butterfly valve of the bag-in-box. Then, the handle 82 is swung downward. The handle 82 drives the claw seat plate 5 to slide downward on the guide rod through the connecting rod 83, so that the claw seat plate 5 drives the lid clamping assembly 6 to move towards the butterfly valve of the bag-in-box. During the process of the lid clamping assembly 6 moving towards the butterfly valve of the bag-in-box, the butterfly valve of the bag-in-box is snapped between several lid clamping pieces 62 and pushes the lid clamping pieces 62 to slide radially outward along the lid clamping seat 61 on the lid clamping seat 61, and at the same time compresses the tension spring 63. As the lid clamping pieces 62 slide, the edge of the butterfly valve of the bag-in-box is snapped into the lid clamping groove 621. Several lid clamping pieces 62 cooperate to clamp the butterfly valve of the bag-in-box under the reset action of the tension spring 63. Then, the handle 82 is swung upward. The handle 82 drives the claw seat plate 5 through the connecting rod 83 and then drives the lid clamping assembly 6 to move upward, so that the lid clamping assembly 6 pulls out the butterfly valve of the bag-in-box clamped and fixed by the lid clamping pieces 62 from the faucet of the bag-in-box. Then, the handle 82 is horizontally swung. The handle 82 drives the claw seat plate 5 and drives the lid clamping assembly 6 and the filling assembly 7 to rotate, so that the lid clamping assembly 6 drives the butterfly valve of the bag-in-box to leave the position aligned with the bag slot 41, and the filling assembly 7 moves to the position aligned with the bag slot 41, so that the discharge port of the material cylinder 71 is aligned with the faucet of the bag-in-box. Then, the handle 82 is swung downward. The handle 82 drives the material cylinder 71 to move downward so that the discharge port of the material cylinder 71 is connected to the faucet of the bag-in-box. At this time, the centrifugal pump 73 works to pump the material in the storage container into the material cylinder 71. The filling cylinder 72 drives the pushing plate to slide in the material cylinder 71 and fills the material in the material cylinder 71 into the bag-in-box through the faucet of the bag-in-box. After the filling is completed, the handle 82 is swung upward to separate the material cylinder 71 from the faucet of the bag-in-box. Then, the handle 82 is horizontally rotated to drive the lid clamping assembly 6 to align with the bag slot 41. The handle 82 is swung downward to drive the lid clamping assembly 6 and drive the butterfly valve of the bag-in-box to press it into the faucet of the bag-in-box, completing the filling operation of the bag-in-box. During the above process, the reset tension spring 84 is stretched when the handle 82 swings, thereby providing a restoring force for the reset of the handle 82, facilitating the operator to operate the handle 82 for the filling operation. It can be seen that this liquid bag-in-box filling machine can realize the filling operation of the bag-in-box, and has a simple and compact structure, making the overall volume smaller, the cost lower, and being more suitable for household and small-scale commercial use.

[0027] Preferably, a limit block 85 is fixedly connected to the guide post 3 on one side of the rotating seat. A limit groove 851 is formed in the limit block 85. One end of the rotating block 81 is held in the limit groove 851. With the above structure, when the handle 82 swings horizontally, the rotating block 81 rotates on the guide post 3. The rotation amplitude of the rotating block 81 is limited by the abutment between the rotating block 81 and the bottom of the limit groove 851, so as to limit the horizontal rotation of the handle 82. When the handle 82 rotates horizontally to two limit positions, the lid clamping assembly 6 and the filling assembly 7 are respectively aligned with the bag clamping groove 41, which facilitates the operation of the operator during the filling operation.

[0028] Preferably, a return cylinder 86 with an upward output shaft is arranged on the frame 1 below the rotation path of the claw seat plate 5. With the above structure, when the handle 82 swings downward to drive the lid clamping assembly 6 or the filling assembly 7 to complete the lid clamping operation or the filling operation, the output shaft of the return cylinder 86 jacks up the claw seat plate 5 upward, which facilitates the operation of the operator during the filling operation.

[0029] Preferably, a shock-absorbing sleeve 31 is sleeved on the guide post 3 above the claw seat plate 5. With the above structure, the shock-absorbing sleeve 31 limits the longitudinal movement of the claw seat plate 5 on the guide post 3, prevents the claw seat plate 5 from moving excessively, and provides a shock-absorbing effect when the claw seat plate 5 slides upward under the jacking of the return cylinder 86.

[0030] Preferably, a waste hopper 9 is arranged on the frame 1 below the material cylinder 71 when the lid clamping assembly 6 is aligned with the bag clamping groove 41. With the above structure, after the filling operation is completed and reset, the waste material in the material cylinder 71 falls into the waste hopper 9 for collection, avoiding the waste material from falling and polluting the working environment.

[0031] Preferably, two adjusting plates 11 are arranged on the frame 1 and are respectively located on both sides of the end of the workbench plate 2. A longitudinal adjusting groove 111 is formed in the adjusting plate 11, and an adjusting bolt 12 screwed to the workbench plate 2 penetrates through the adjusting groove 111. A first adjusting screw rod 13 that can swing longitudinally is hinged to the lower surface of the workbench plate 2, and a second adjusting screw rod 14 that can swing longitudinally is hinged to the frame 1. An adjusting sleeve 15 screwed to the second adjusting screw rod 14 is screwed on the first adjusting screw rod 13. With the above structure, after loosening the adjusting bolt 12, rotate the adjusting sleeve 15. Through the threaded cooperation of the adjusting sleeve 15 with the first adjusting screw rod 13 and the second adjusting screw rod 14, drive the overall length of the first adjusting screw rod 13, the adjusting sleeve 15 and the second adjusting screw rod 14, and then adjust the position of the front end of the workbench plate 2. Then, cooperate with the sliding of the adjusting bolt 12 in the adjusting groove 111 to adjust the position of the rear end of the workbench plate 2, and the horizontal position of the workbench plate 2 can be adjusted, and then the distance between the workbench plate 2 and the bag clamping seat 4 can be adjusted to adapt to the filling operation of the bag-in-box of different sizes, so that the filling machine has better applicability.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
