Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 15 As shown, this adjustable continuous rinsing system of the present invention includes a machine base 1, multiple drive rollers 2 mounted on the machine base 1, a support plate 20, and a retaining assembly 21. The drive rollers 2 can rotate on the machine base 1, and the distance between the drive rollers 2 can be adjusted to accommodate test tubes of different diameters. Silicone can be coated on the outside of the drive rollers 2 to prevent slippage between the test tubes and the drive rollers 2. The support plate 20 is used to change the tilt angle of the drive rollers, allowing them to rotate between 0-15°. The retaining assembly 21 is used to restrict the position of the test tubes within the adjustment gap 26, so that tilted test tubes can be blocked by the baffle 32 and will not move out of the drive rollers 2.

[0020] The machine base 1 is equipped with a support plate 79, and a sliding seat 3 is mounted on the support plate 79. Mounting seats 4 are located at both ends of the sliding seat 3. A motor 5 is mounted on one of the mounting seats 4 and is fixed to it. A rotating shaft 6 is mounted on the motor 5 and is positioned in the middle of the mounting seat 4. A bearing can be installed in the middle of the mounting seat 4, and the rotating shaft 6 is positioned in the middle of the bearing.

[0021] The rotating shaft 6 is provided with multiple first bevel gears 13 and movable seats 18. The first bevel gears 13 are in contact with the movable seats 18. A plane bearing can be provided between the first bevel gears 13 and the movable seats 18 to avoid wear between the two parts.

[0022] The transmission roller 2 is mounted on the machine base 1. A rotating rod 23 is provided in the middle of the transmission roller 2. One end of the transmission roller 2 is connected to the moving seat 18 through the rotating rod 23, and the other end is mounted on the machine base 1 through the rotating rod 23. An adjustment gap 26 is formed between the transmission roller 2 and the transmission roller 2. The test tube or sample tube that needs to be cleaned is placed in the adjustment gap 26. A second bevel gear 24 that cooperates with the first bevel gear 13 is provided on the rotating rod 23.

[0023] The rotating shaft 6 consists of multiple connecting rods 7 and 8, with the diameter of the first rod 7 being larger than that of the second rod 8. The first rod 7 has an external thread 9, the second rod 8 has a sliding groove 10, and the first rod 7 has a nut 11 with an internal thread 12 in the center. The first bevel gear 13 has a sliding protrusion 16 that mates with the sliding groove 10. A sliding hole 15, mates with the second rod 8, is located in the center of the first bevel gear 13, and the sliding protrusion 16 is positioned within the sliding hole 15.

[0024] The first bevel gear 13 is a structure composed of two half-bevel gears 14. During installation, the two half-bevel gears 14 need to be fixed to the second rod 8 so that the sliding protrusion 16 cooperates with the sliding groove 10, thereby allowing the first bevel gear 13 to move only between the two first rods 7.

[0025] The movable seat 18 is composed of a sliding sleeve 19. A mounting portion 27 is provided on one side of the sliding sleeve 19. One end of the rotating rod 23 is disposed within the mounting portion 27. A bearing can also be disposed within the mounting portion 27, and the rotating rod 23 is then positioned in the middle of the bearing. A through hole 22 is formed in the middle of the sliding sleeve 19 to mate with the first rod body 7. The inner diameter of the through hole 22 is larger than the outer diameter of the first rod body 7. The diameter of the through hole 22 is slightly larger than the outer diameter of the first rod body 7, allowing the through hole 22 to slide on the external thread 9. The movable seat 18 can be held in place by the push of the nut 11, which pushes the first bevel gear 13 to compress the first spring 17.

[0026] The sliding sleeve 19 has a ring 31, on which a plane bearing can be installed, and the ring bearing contacts the first bevel gear 13.

[0027] A first spring 17 is fitted onto the second rod 8. One end of the first spring 17 contacts the first bevel gear 13, and the other end contacts another part of the first rod 7. The first spring 17 is used to apply pressure to the first bevel gear 13, thereby keeping the first bevel gear 13 and the moving seat 18 in contact at all times, that is, ensuring that the first bevel gear 13 and the second bevel gear 24 are always in a meshing connection.

[0028] The machine base 1 is also equipped with a positioning plate 28, with a strip hole 29 in the middle. The rotating rod 23 is placed in the strip hole 29. A second spring 25 and a rotating component 30 are sleeved on the rotating rod 23. One end of the second spring 25 contacts the rotating component 30, and the other end contacts the positioning plate 28. The rotating component 30 can be installed on the rotating rod 23 by means of threads.

[0029] When the spacing between the drive rollers 2 changes, the rotating rod 23 remains sliding in the strip hole 29.

[0030] The support plate 20 is set on the machine base 1. One end of the support plate 20 is hinged to the machine base 1 through the first hinge rod 33, and the other end remains in a movable state. The support plate 20 is provided with a hinge block 34, and the machine base 1 is provided with a receiving opening 35 that cooperates with the hinge block 34.

[0031] A symmetrically arranged cylinder 36 is provided in the middle of the machine base 1. One end of the cylinder 36 is hinged to the inner wall of the machine base 1, and the other end is hinged to the lower end of the support plate 20. A push rod 37 is provided on the cylinder 36, and a push sleeve 38 is provided on the push rod 37. A first hinge 39 is provided at the lower end of the support plate 20, a second hinge 40 is provided on the inner wall of the machine base 1, and a third hinge 41 is provided at the lower end of the cylinder 36. The first hinge 39 and the push sleeve 38 are hinged together by a first hinge shaft 42, and the second hinge 40 and the third hinge 41 are hinged together by a second hinge shaft 43. When the cylinder 36 is activated, it can push the support plate 20 to rotate around the first hinge rod 33, thereby changing the angle of the support plate 20. Since one end of the transmission roller 2 is set on the positioning plate 28 on the support plate 20, the positioning plate 28 will drive the transmission roller to change its tilt angle.

[0032] Because the first hinge rod 33 and the rotating shaft 64 are not at the same position and their center lines do not coincide, the range of rotation of the support plate 20 and the transmission roller 2 will be different, and the angle of rotation will also be different. If the support plate 20 is rotated around the rotating shaft 64, it will affect the connection between the transmission roller 2 and the moving seat 18. Therefore, by setting a universal rod 45 and a rotatable positioning plate 28 on the rotating rod 23, the angle between the transmission roller 2 and the support plate 20 can be adjusted so that the transmission roller 2 and the support plate 20 can remain parallel during rotation.

[0033] A positioning plate 28 is provided at one end of the support plate 20 in the movable state. Hinges 46 are provided on both sides of the positioning plate 28 and are mounted on the support plate 20. The hinges 46 and the positioning plate 28 are hinged together by a second hinge rod 47, allowing the positioning plate 28 to rotate. A slotted hole 48 is provided in the middle of the positioning plate 28. A universal joint 45 is also provided on the rotating rod 23. The universal joint 45 is connected to the rotating rod 23 through a universal head 49. The universal joint 45 is placed inside the slotted hole 48. A second spring 25 and a rotating component 30 are fitted on the universal joint 45. One end of the second spring 25 contacts the rotating component 30, and the other end contacts the positioning plate 28.

[0034] Because a rotating component 30 is provided on the universal rod 45, and the rotating component 30 and the universal rod 45 are connected by a thread, the rotating component 30 can be rotated to compress the second spring 25. This causes the second spring 25 to generate a large elastic potential energy, changing the elastic potential energy of the second spring 25. Therefore, when the universal rod 45 and the rotating rod 23 tilt (i.e., their center lines do not coincide), the second spring 25 can promptly pull the universal rod 45, thus maintaining the center lines of the universal rod 45 and the rotating rod 23 in a state of alignment. This ensures that after the adjustment gap 26 between the transmission rollers 2 changes, the second spring 25 automatically adjusts the position of the rotating rod 23 toward the positioning plate 28, allowing the universal rod 45 to move along with the rotating rod 23 within the slot 48.

[0035] The retaining assembly 21 is mounted on the support plate 20. The retaining assembly 21 includes a baffle 32, a retaining seat 50, and symmetrically arranged retaining blocks 51. The baffle 32 prevents the test tube from falling out of the adjustment gap 26 during tilted cleaning. A third spring 52 is provided between the retaining blocks 51. The retaining seat 50 is mounted on the support plate 20 and has a retaining groove 54 that mates with the baffle 32. The retaining block 51 is hinged to the middle of the retaining seat 50 via a pin 55. When the baffle 32 is inserted into the retaining groove 54, the symmetrically arranged retaining blocks 51 restrict the position of the baffle 32.

[0036] The retaining seat 50 consists of a retaining body 56 and an extension body 57. The retaining body 56 is mounted on the support plate 20. The lower end of the extension body 57 forms a gap region 58, which is used to keep the lower end of the retaining block 51 empty, allowing the lower end of the extension body 57 to be pressed. The extension body 57 has symmetrically arranged retaining openings 59, and the retaining block 51 is disposed in the retaining openings 59. The retaining groove 54 has symmetrically arranged inner grooves 60, which are connected to the retaining openings 59 through a connecting hole 61. The limiting body 62 passes through the connecting hole 61 and enters the inner groove 60 to limit the position of the fixing block 63, thereby limiting the baffle 32.

[0037] The retaining block 51 consists of a limiting end 64, a free end 65, and a hinge portion 66. A pin 55 is positioned in the middle of the hinge portion 66. The limiting end 64 has a limiting surface 67, and a limiting body 62 is provided on the limiting surface 67. The limiting body 62 has an arc surface 68 and a clearance slope 69. The clearance slope 69 is used to avoid the position of the limiting body 62, allowing the limiting body 62 to rotate through the connecting hole 61 into the retaining opening 59. The retaining block 51 has a first contact surface 70 and a first limiting surface 71. The retaining opening 59 has a second contact surface 72 that mates with the first contact surface 70 and a second limiting surface 73 that mates with the first limiting surface 71.

[0038] A through hole 74 is provided on the second limiting surface 73, and a third spring 52 is disposed in the through hole 74. A small hole 75 is provided on the retaining block 51 to accommodate the third spring 52. The third spring 52 pushes the lower end of the retaining block 51, so that the upper end of the retaining block 51 can enter the inner groove 60 through the connecting hole 61.

[0039] The baffle 32 consists of a blocking body 76 and a fixing body 77. The height of the fixing body 77 is greater than the height of the blocking body 76. The blocking body 76 is located above the transmission roller 2. The fixing body 77 is installed in conjunction with the retaining groove 54. The fixing body 77 is provided with symmetrically arranged fixing blocks 63. One side of the fixing block 63 is a guide slope 78 that cooperates with the arc surface 68, and the other side is a blocking surface 48.

[0040] When the baffle 32 needs to be installed, simply align the fixing block 63 with the retaining groove 54, and push the arc surface 68 through the guide slope 78, so that the limiting body 62 pushes the retaining block 51 to rotate around the pin shaft 55, keeping the first limiting surface 71 and the second limiting surface 73 in contact.

[0041] When removing the baffle 32, simply press the free end 65 towards the center, compressing the third spring 52. This causes the limiting body 62 to move into the retaining opening 59, no longer restricting the position of the fixing block 63, allowing the baffle 32 to be removed. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
