Description

Technical Field

[0001] This utility model relates to the field of floor scrubber assembly technology, specifically to a semi-automatic insertion machine for floor scrubber filter hoses. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously vacuuming up and removing wastewater from the site. It boasts advantages such as environmental friendliness, energy efficiency, and high performance. Common types include semi-automatic, fully automatic, walk-behind, and ride-on floor scrubbers. A typical floor scrubber consists of four main parts: an electric roller brush, a wastewater tank, a clean water tank, and a motor. During operation, clean water flows from the clean water tank through a water pipe onto the roller brush. The roller brush, driven by the motor, rotates rapidly, separating dirt from the floor. Simultaneously, suction creates a vacuum in the wastewater tank, drawing the wastewater from the roller brush into it, keeping the brush clean. To prevent clogging, most existing floor scrubbers have filters in their clean water and wastewater tanks. These filters are connected to hoses to facilitate the transport of clean and wastewater. Figure 1 This example illustrates a common filter element, which is a six-sided box-shaped body. The top surface has a connector (hollow cylinder) for connecting a flexible tube, while the other five sides have mesh for filtration. During assembly, the flexible tube needs to be manually inserted into the connector. Since the flexible tube and connector are tightly fitted to prevent leakage, the insertion is laborious. After prolonged insertion, the operator's fingers will experience significant pain. In addition, the degree of insertion varies from person to person, making it difficult to ensure consistent assembly. Utility Model Content

The slot 211 penetrates the upper surface and the rear surface of the filter placement platform 21. The hose placement platform 22 is disposed behind the filter placement platform 21. The upper surface of the hose placement platform 22 is provided with a groove 221 for placing the hose 2. The groove 221 penetrates the front surface and the rear surface of the hose placement platform 22 and is aligned with the rear opening of the slot 211. The clamping assembly is disposed between the filter placement platform 21 and the hose placement platform 22. The clamping assembly includes grippers disposed on the left and right sides of the axis of the groove 221. The grippers are disposed above the base plate 10 and can open and close left and right and can move back and forth. There is a gap between the gripper and the base plate 10. The rear corner of the gripper on the back side is provided with a first inclined surface 31 that extends outward and forward. The drive assembly includes a drive block 41 that can move back and forth, a cylinder 42 for driving the drive block 41 to move back and forth, the front end of the drive block 41 is provided with a second inclined surface 411 that corresponds to and matches the first inclined surface 31, and a step 412 connected to the second inclined surface 411. The step 412 is located behind the second inclined surface 411. When the drive block 41 moves forward, the second inclined surface 411 and the first inclined surface 31 fit together and slide against each other, so that the gripper closes, clamps the hose 2 and drives the hose 2 to move forward and align (so that the front end of the hose 2 is aligned and inserted into the connector 3 of the filter element 1). When the second inclined surface 411 disengages from the first inclined surface 31, the step 412 presses against the rear surface of the gripper, so that the gripper moves forward and inserts the hose 2 into the connector 3 of the floor scrubber filter element 1.

[0031] The advantage of this setup is that you only need to place the filter element and the tubing; there is no need for manual insertion. It is simple to operate, saves time and effort, is highly efficient, and ensures good consistency in insertion.

When the second inclined surface 411 and the first inclined surface 31 are in contact and slide against each other, the connecting rod 325 causes the clamping block 32 to move forward while closing.

[0035] To improve the stability of the clamping block 32 during movement, in this embodiment, two connecting rods 325 are inserted in the mounting groove 324. These two connecting rods 325 are spaced apart in the left and right direction, forming a four-bar linkage with the clamping block 32 and the base plate 10.

[0036] Furthermore, the base plate 10 is provided with a wear-resistant plate 11 and a positioning plate 12. The wear-resistant plate 11 is slidably attached to the base plate 10 and located below the clamping block 32. The positioning plate 12 is sleeved on the positioning key 13 on the base plate 10 and located below the hose placement platform 22. The front end of the connecting rod 325 is also rotatably connected to the wear-resistant plate 11. The connecting rod 325, the mounting groove 324, and the wear-resistant plate 11 are rotatably connected through the same screw. The rear end of the connecting rod 325 is rotatably connected to the positioning plate 12. The rear end of the connecting rod 325 is also rotatably connected to the hose placement platform 22. The connecting rod 325, the hose placement platform 22, and the positioning plate 12 are rotatably connected through the same screw.

[0037] To achieve avoidance, in this embodiment, the surface of the clamping block 33 facing the other side is provided with a receiving groove 331 for accommodating the hose 2. When the clamping block 32 closes and clamps the hose 2, the groove wall of the receiving groove 331 is attached to and abuts against the outer wall of the hose 2.

[0038] To achieve a floating connection, the clamping block 33 is slidably connected to the protrusion 322 via the guide rod 332. The guide rod 332 extends along the opening and closing direction of the clamping block 32, and a floating spring (not shown in the figure) is sleeved on the guide rod 332. The two ends of the floating spring abut against the clamping block 33 and the protrusion 322 respectively.

[0039] In order to guide the drive block 41, in this embodiment, the drive block 41 is provided with guide grooves 413 extending in the front-back direction on both sides, and a guide block 14 is connected to the bottom plate 10. A part of the guide block 14 is embedded in the guide groove 413. The drive block 41 is also provided with an avoidance groove 414 for aligning the groove 221 to accommodate a longer hose 2.

[0040] In this embodiment, the cylinder 42 is mounted on the base plate 10 and located behind the drive block 41. The cylinder rod end of the cylinder 42 is connected to a push plate 421, which is locked onto the rear surface of the drive block 41.
