[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0019] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Example: A coffee extraction tank cleaning device includes a conveyor line 1, a cleaning mechanism 3, a scrubbing mechanism 4, a spraying mechanism 5, a high-temperature sterilization mechanism 6, and a tilting device 7. The conveyor line 1 is used to transport the inverted extraction tank horizontally; the cleaning mechanism 3 is used to spray water from bottom to top into the extraction tank to rinse the inner wall of the extraction tank; the scrubbing mechanism 4 is used to scrub the inner wall of the extraction tank after rinsing on the conveyor line 1; the spraying mechanism 5 is used to spray and rinse the inside and outside of the extraction tank after scrubbing on the conveyor line 1; the high-temperature sterilization mechanism 6 is used to sterilize the extraction tank after spraying and rinsing with high-temperature steam; and the tilting device 7 is used to tilt the extraction tank from inverted to upright after high-temperature sterilization.

[0021] During the cleaning process, the extraction vessel with coffee grounds poured out is inverted on the conveyor line 1. The conveyor line 1 drives the extraction vessel through the cleaning mechanism 3, the brushing mechanism 4, the spraying mechanism 5, and the high-temperature sterilization mechanism 6 in sequence. Then, the inverted extraction vessel is flipped to the upright position by the flipping device 7, which makes it convenient to use the extraction vessel later.

[0022] Specifically, the conveyor line 1 includes a transmission chain 11, sprockets 12, and drive shafts 13. There are two transmission chains 11 arranged side by side. Two sprockets 12 are provided at both ends of each transmission chain 11, and the transmission chains 11 are arranged in a closed loop around the corresponding two sprockets 12. There are two drive shafts 13, which are respectively provided at both ends of the transmission chain 11. The drive shafts 13 are coaxial with the two sprockets 12 at both ends of the transmission chain 11, and the ends of the drive shafts 13 are fixedly connected to the coaxial sprockets 12.

[0023] Specifically, the cleaning mechanism 3, the brushing mechanism 4, the spraying mechanism 5, the high-temperature sterilization mechanism 6, and the flipping device 7 each correspond to at least one conveyor line 1. For the cleaning mechanism 3, the brushing mechanism 4, the spraying mechanism 5, and the high-temperature sterilization mechanism 6, the conveyor line 1 is also equipped with a limiting mechanism 2 for positioning the inverted extraction tank.

[0024] Specifically, the limiting mechanism 2 includes side baffles 21 and support plates 22. At least one set of side baffles 21 is provided, with two side baffles in each set. The two side baffles 21 of the same set are respectively positioned on top of the two conveyor chains 11, and the side baffles 21 are vertical and parallel to the conveying direction of the conveyor chains 11. Two support plates 22 are provided, horizontally positioned with their length direction perpendicular to the conveying direction of the conveyor chains 11. Both ends of the support plates 22 are fixedly connected to the two conveyor chains 11. The side baffles 21 are positioned between the two support plates 22, and the extraction tank is supported on the two support plates 22. In this embodiment, two sets of side baffles 21 are provided, and the two sets of side baffles 21 are arranged along the conveying direction of the conveyor line 1.

[0025] The extraction vessel is inverted on two support plates 22 and the two sides of the extraction vessel are limited by two sets of side baffles 21.

[0026] Specifically, the limiting mechanism 2 also includes a transmission baffle 23. Two transmission baffles 23 are provided, and the two transmission baffles 23 are respectively fixedly connected to the two opposite sides of the top of the two support plates 22. The transmission baffles 23 are perpendicular to the support plates 22 and parallel to the support plates 22 in the length direction.

[0027] By setting the transfer baffle 23, the front and rear sides of the extraction tank along the conveying direction of the conveyor line 1 can be limited.

[0028] Specifically, the limiting mechanism 2 also includes a connecting plate 24. The bottom of each side baffle 21 is fixedly connected to a connecting plate 24 connected to the transmission chain 11, and the connecting plate 24 extends toward another transmission chain 11.

[0029] The connecting plate 24 helps the support plate 22 to support the extraction tank.

[0030] Specifically, the cleaning mechanism 3 includes a cleaning pipe 33 and a nozzle 52. The cleaning pipe 33 is used to provide high-pressure water. The nozzle 52 is fixedly connected to the top of the cleaning pipe 33 and is used to spray water onto various parts of the inner wall of the extraction tank that has moved above the nozzle 52.

[0031] In some embodiments, the cleaning tube 33 can be moved vertically to extend the nozzle 52 into the extraction tank above the nozzle 52, so as to better rinse the various parts of the inner wall of the extraction tank.

[0032] Specifically, this embodiment also includes a cleaning hood 34, which is placed above the cleaning mechanism 3, and the extraction tank can enter and exit the cleaning hood 34 along the transmission direction of the conveyor line 1.

[0033] Specifically, this embodiment also includes a wastewater tank 35, which is located below the cleaning mechanism 3 to contain the water left after the spray extraction tank.

[0034] Specifically, the scrubbing mechanism 4 includes a scrubbing rod 42, a scrubbing seat 41, and brush bristles. The axis of the scrubbing rod 42 is vertical. The scrubbing seat 41 can slide in the vertical direction, and the scrubbing rod 42 is rotatably connected to the scrubbing seat 41. Several brush bristles are fixedly connected to the outside of the scrubbing rod 42. When the scrubbing rod 42 extends into the extraction tank, the brush bristles contact the inner wall of the extraction tank.

[0035] When the inverted extraction vessel is moved directly above the scrubbing mechanism 4, the scrubbing base 41 moves upward, causing the scrubbing rod 42 to be inserted into the extraction vessel. This causes the bristles on the scrubbing rod 42 to contact the inner wall of the extraction vessel. Then, the scrubbing rod 42 rotates on the scrubbing base 41, and the rotation of the scrubbing rod 42 causes the bristles to scrub various parts of the inner wall of the extraction vessel.

[0036] Specifically, the brush holder 41 is equipped with a motor that drives the brush rod 42 to rotate, and the motor is connected to the brush rod 42 in a transmission connection.

[0037] Specifically, the brushing rod 42 is configured as a hollow tube or a water supply pipe is connected to the brushing rod 42; the brushing mechanism 4 also includes several nozzles 52, which are connected to the brushing rod 42 or the water supply pipe for spraying water onto the inner wall of the extraction tank. In this embodiment, the brushing rod 42 is configured as a hollow tube and is connected to the water supply pipe 53, so that when the brush bristles brush the inner wall of the extraction tank, the water sprayed from the nozzles 52 carries the coffee grounds brushed off by the brush bristles downwards and detaches them from the extraction tank.

[0038] Specifically, the washing mechanism 4 also includes a washing cover 44, which is placed on top of the conveyor line 1 and located above the washing mechanism 4. The extraction tank can pass through the washing cover 44, and a small gap is left between the top of the extraction tank and the top of the washing cover 44 when the extraction tank passes through the washing cover 44.

[0039] The small gap here refers to the distance between the top of the extraction tank and the top of the brush cover 44 being less than the height of the side baffle and the transmission baffle 23. This prevents the extraction tank from being pushed upward by the brush rod 42 and falling out of the limit of the side baffle and the transmission baffle 23. After the extraction tank is pushed up and comes into contact with the brush cover 44, the friction between the brush cover 44 and the extraction tank can prevent the extraction tank from rotating in the same direction and at the same speed as the brush rod 42. This allows the bristles to generate relative displacement with the inner wall of the extraction tank, thus achieving the brushing of the inner wall of the extraction tank by the bristles.

[0040] Specifically, the spraying mechanism 5 includes a spray pipe 51 and a nozzle 52. The spray pipe 51 is rectangular and surrounds the outside of the conveyor line 1. The extraction tank conveyed by the conveyor line 1 passes through the annular spray pipe 51. The top and bottom of the spray pipe 51 are horizontal and the two sides are vertical. Each side of the spray pipe 51 is perpendicular to the conveying direction of the conveyor line 1. At least one nozzle 52 is provided on the inner side of each side of the spray pipe 51. The nozzle 52 is used to spray water toward the extraction tank that passes through the spray pipe 51.

[0041] The nozzles 52 on the four inner sides of the spray pipe 51 can spray water onto the top, bottom and two sides of the extraction tank respectively. Since the extraction tank is a cylindrical structure, the front and rear sides along the conveying direction of the conveying line 1 can also be rinsed by the nozzles 52 on both sides of the conveying line 1, so that the interior and exterior of the extraction tank can be uniformly sprayed and rinsed.

[0042] Specifically, the spraying mechanism 5 includes multiple spray pipes 51, which are arranged along the transmission direction of the transmission line.

[0043] Specifically, the spraying mechanism 5 also includes a water supply pipe 53, which is connected to a high-pressure water pump and is connected to multiple spray pipes 51 to supply water to the multiple spray pipes 51.

[0044] Specifically, the spraying mechanism 5 also includes a collection hopper 55 and a recovery box 56. The collection hopper 55 is located below the multiple spray pipes 51 to collect the water after rinsing the extraction tank. The recovery box 56 is located at the bottom of one side of the collection hopper 55, with an open top and a drain outlet for discharging water into the recovery box 56 at the bottom of the side of the collection hopper 55 closest to the recovery box 56. The arrangement of the collection hopper 55 and the recovery box 56 facilitates the collection and reuse of the water after rinsing the extraction tank.

[0045] Specifically, there are multiple spraying mechanisms 5, which are evenly arranged along the conveying direction of the conveyor line 1. Each spraying mechanism 5 corresponds to a collection hopper 55 and a recycling box 56.

[0046] Specifically, the spraying mechanism 5 also includes a spray hood 54, which covers the outside of the spraying mechanism 5.

[0047] Specifically, the high-temperature sterilization mechanism 6 includes a sterilization pipe 61 and sterilization nozzles 62. The sterilization pipe 61 is located between the two transmission chains 11 of the conveyor line 1. The inverted extraction tank moves above the sterilization pipe 61. The length of the sterilization pipe 61 is set along the conveying direction of the conveyor line 1. The sterilization nozzles 62 are located at the top of the sterilization pipe 61. Several sterilization nozzles 62 are provided at the top of the sterilization pipe 61. The sterilization nozzles 62 are used to spray high-temperature steam upwards to achieve high-temperature sterilization of the extraction tank passing through the sterilization pipe 61.

[0048] Specifically, the high-temperature sterilization mechanism 6 also includes a sterilization hood 63, which is installed on the conveyor line 1 and covers the sterilization pipe 61 inside. The conveyor line 1 drives the extraction tank through the sterilization hood 63, so that the extraction tank can be sterilized during the process of passing through the sterilization hood 63.

[0049] Specifically, the flipping device 7 includes a clamping mechanism 72 and a flipping mechanism 73. The conveyor line 1 is used to transport the inverted extraction tank. The clamping mechanism 72 is used to clamp the inverted extraction tank conveyed on the conveyor line 1. The flipping mechanism 73 is located at the top of the conveyor line 1. The flipping mechanism 73 can drive the clamping mechanism 72 to flip around a horizontal axis perpendicular to the conveying direction of the conveyor line 1 to flip the inverted extraction tank to the upright position.

[0050] The conveyor line 1 transports the inverted extraction tank to the adjacent flipping mechanism 73. The inverted extraction tank is clamped by the clamping mechanism 72, and then the flipping mechanism 73 drives the clamping mechanism 72 and the extraction tank to flip together, thereby flipping the extraction tank to be upright on the conveyor line 1.

[0051] Specifically, the clamping mechanism 72 includes two grippers 721, which slide along a direction parallel to the rotation axis of the clamping mechanism 72 to clamp and release the extraction vessel.

[0052] Specifically, the clamping mechanism 72 also includes a rotating seat 722 and a dual-axis bidirectional cylinder 723. The rotating seat 722 is connected to the flipping mechanism 73. The dual-axis bidirectional cylinder 723 is fixedly connected to the rotating seat 722 and is used to drive the two grippers 721 to move.

[0053] Specifically, the two grippers 721 have an arc-shaped portion on their sides that are close to each other, which fits against the outside of the extraction vessel. The arc-shaped portion makes the gripper 721 hold the extraction vessel more stably when clamping it.

[0054] Specifically, the flipping mechanism 73 includes a flipping seat 731 and a flipping shaft 732. Two flipping seats 731 are provided and are respectively provided on both sides of the top of the conveyor line 1. The two ends of the flipping shaft 732 are rotatably connected to the two flipping seats 731 respectively, and the flipping shaft 732 is connected to the rotating seat 722.

[0055] Specifically, the flipping device 7 also includes a blocking mechanism 74, which is disposed above the conveyor line 1. The extraction tank passes through the blocking mechanism 74 and the flipping mechanism 73 in sequence on the conveyor line 1. The blocking mechanism 74 is used to block the next extraction tank during the flipping process of the extraction tank by the flipping mechanism 73.

[0056] Specifically, the blocking mechanism 74 includes a rotating frame 741 and a blocking rod 742. The rotating frame 741 is disposed above the conveyor line 1, and the end of the rotating frame 741 away from the flipping mechanism 73 rotates around a vertical axis. The blocking rod 742 is vertically disposed and fixedly connected to the end of the rotating frame 741 away from the rotation axis. The blocking rod 742 blocks and releases the extraction tank through the rotation of the rotating frame 741.

[0057] Specifically, the blocking mechanism 74 also includes a blocking cylinder 743, which is used to drive the rotating frame 741 to rotate.

[0058] Specifically, the rotating shaft 732 is driven by a servo motor or a cylinder to rotate. When the rotating shaft 732 drives the extraction tank to rotate, the rotation speed of the rotating shaft 732 is controlled so that the extraction tank will not have a hard impact with the conveyor line 1 when it rotates to the upright position and falls onto the conveyor line 1.
