DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0023] Embodiments of the present utility model: Figure 1-Figure 5 As shown, an electronic belt scale roller self-cleaning device includes a box body 1, a roller clamping assembly is arranged in the box body 1, an outer sleeve 10 is fixedly arranged at one end of the box body 1, the outer sleeve 10 is communicated with the box body 1, an inner conduit 11 is plugged and slidably connected with the outer sleeve 10, an end of the inner conduit 11 located in the box body 1 is provided with a support structure, and a plurality of liquid spray holes 111 are opened on the top surface of the end of the inner conduit 11.

[0024] By arranging an opening mechanism in the box body 1, the electronic belt scale roller to be cleaned can be clamped by the opening mechanism, and the staff does not need to hold the cleaning device all the time. Then, by introducing cleaning liquid into the inner conduit 11, the cleaning liquid is sprayed through the spray hole 111 to clean the surface of the electronic belt scale roller. This not only ensures the cleaning effect, but also saves time and effort and improves work efficiency.

[0025] In a specific embodiment, the box body 1 is composed of a rectangular bottom plate 18, a first end plate 19, a second end plate 20, a first side plate 21 and a second side plate 22. The first end plate 19, the second end plate 20, the first side plate 21 and the second side plate 22 are respectively fixed on the four sides of the rectangular bottom plate 18, the first end plate 19 and the second end plate 20 are arranged opposite to each other, and the first side plate 21 and the second side plate 22 are arranged opposite to each other.

[0026] The tops of the first end plate 19 and the second end plate 20 are both formed with arc grooves 2, and sponge water retaining strips 23 are fixed on the arc grooves 2. The box body 1 surrounded by the rectangular bottom plate 18, the first end plate 19, the second end plate 20, the first side plate 21 and the second side plate 22 can store sewage. The sponge water retaining strips 23 can prevent sewage and cleaning liquid from flowing out of the gap between the electronic belt scale roller and the arc groove 2, ensuring that the cleaning liquid and water are sprayed onto the surface of the electronic belt scale roller and fall into the box body 1 for storage.

[0027] Furthermore, the roller clamping assembly includes a first wheel frame 3 and a second wheel frame 4, the first wheel frame 3 and the second wheel frame 4 are arranged opposite to each other, the first wheel frame 3 is movably mounted on the first side plate 21 through two first guide rods 24, and the second wheel frame 4 is movably mounted on the second side plate 22 through two second guide rods 25, four first support wheels 5 are arranged on the first wheel frame 3, four second support wheels 6 are arranged on the second wheel frame 4, and the first wheel frame 3 and the second wheel frame 4 are connected by a tension spring 7.

[0028] Specifically, the first wheel frame 3 and the second wheel frame 4 are both U-shaped structures, the two first guide rods 24 on the first wheel frame 3 are arranged at the same height, and the first side plate 21 is provided with two through holes for installing the first guide rods 24, and the two second guide rods 25 on the second wheel frame 4 are also arranged at the same height, and the second side plate 22 is provided with two through holes for installing the second guide rods 25. Through this structural design, the first wheel frame 3 and the second wheel frame 4 will not be skewed when moving, so that the first wheel frame 3 and the second wheel frame 4 can effectively clamp the electronic belt scale rollers.

[0029] Two of the four first support wheels 5 are rotatably mounted on the upper part of the first wheel frame 3, and the other two are rotatably mounted on the lower part of the first wheel frame 3; two of the four second support wheels 6 are rotatably mounted on the upper part of the second wheel frame 4, and the other two are rotatably mounted on the lower part of the second wheel frame 4. The two first support wheels 5 located on the upper part of the first wheel frame 3 are coaxially arranged, and their axes are parallel to the axis of the arc groove 2; the two first support wheels 5 located on the lower part of the first wheel frame 3 are coaxially arranged, and their axes are parallel to the axis of the arc groove 2; the two second support wheels 6 located on the upper part of the second wheel frame 4 are coaxially arranged, and their axes are parallel to the axis of the arc groove 2; the two second support wheels 6 located on the lower part of the second wheel frame 4 are coaxially arranged, and their axes are parallel to the axis of the arc groove 2. The four first support wheels 5 and the four second support wheels 6 cooperate to clamp the roller of the electronic belt scale to be cleaned. The tension spring 7 is arranged on the side close to the second end plate 20.

[0030] Furthermore, a first triangular plate 8 is fixedly provided at the lower end of the inner wall of the first wheel frame 3, and a second triangular plate 9 is fixedly provided at the lower end of the inner wall of the second wheel frame 4. The first triangular plate 8 and the second triangular plate 9 are symmetrically arranged relative to the axis of the rectangular bottom plate 18. The expanded structure is an isosceles trapezoidal plate 12, and the isosceles trapezoidal plate 12 is fixedly provided on the bottom surface of the end of the inner guide tube 11. The hypotenuse on one side of the isosceles trapezoidal plate 12 abuts against the first triangular plate 8, and the hypotenuse on the other side of the isosceles trapezoidal plate 12 abuts against the second triangular plate 9.

[0031] The isosceles trapezoidal plate 12 is driven to move by the inner guide tube 11. When the isosceles trapezoidal plate 12 moves toward the direction close to the second end plate 20, the isosceles trapezoidal plate 12 pushes the first triangular plate 8 and the second triangular plate 9 away from each other, so that the first wheel frame 3 and the second wheel frame 4 are away from each other. When the isosceles trapezoidal plate 12 moves toward the direction close to the first end plate 19, the first triangular plate 8 and the second triangular plate 9 approach each other under the action of the tension spring 7, so that the first wheel frame 3 and the second wheel frame 4 approach each other, clamping the electronic belt scale roller. In this embodiment, the tail end of the isosceles trapezoidal plate 12 also has a rectangular plate, through which the first wheel frame 3 and the second wheel frame 4 can be kept at the farthest distance.

[0032] Furthermore, one end of the inner conduit 11 away from the box body 1 is located outside the outer sleeve 10, and a push-pull rod 13 is fixedly arranged at the end. A water inlet slot 112 is provided at the bottom of the inner conduit 11, and a handle 14 is fixedly connected to the bottom of the end of the outer sleeve 10 away from the box body 1, and a liquid inlet hose 15 runs through the handle 14, and one end of the liquid inlet hose 15 is communicated with the inner cavity of the outer sleeve 10.

[0033] The cleaning liquid enters the outer sleeve 10 through the liquid inlet hose 15, then enters the inner conduit 11 through the water inlet trough hole 112, and finally sprays out from the spray hole 111 at the end of the inner conduit 11 to clean the surface of the electronic belt scale roller.

[0034] Furthermore, sealing rings 16 are fixedly sleeved on the inner walls of both ends of the outer sleeve 10. A drain pipe 17 is connected to the rectangular bottom plate 18, and the drain pipe 17 is arranged parallel to the bottom side of the outer sleeve 10.

[0035] By setting the sealing ring 16, the cleaning liquid introduced from the liquid inlet hose 15 into the outer sleeve 10 is blocked by the sealing ring 16 fixedly sleeved at the front and rear ends thereof, and the cleaning liquid can only enter the inner conduit 11 from the water inlet slot 112, and then spray out from the spray hole 111 to clean the outer wall of the electronic belt scale roller. The drain pipe 17 is used to discharge the clean sewage after cleaning the electronic belt scale roller, and the clean sewage flows back from the bottom side of the outer sleeve 10 to the sewage storage container.

[0036] The working principle of the utility model is as follows: under normal conditions, the first wheel frame 3 and the second wheel frame 4 are brought close to each other under the tension of the tension spring 7; when in use, the inner guide tube 11 is pushed by the push-pull rod 13, and the inner guide tube 11 makes the first wheel frame 3 and the second wheel frame 4 move away from each other through the isosceles trapezoidal plate 12 and the first triangular plate 8 and the second triangular plate 9, and at this time, the first support wheel 5 and the second support wheel 6 also move away from each other until the first triangular plate 8 and the second triangular plate 9 are located on both sides of the rectangular plate at the rear end of the isosceles trapezoidal plate 12, at this time, the push-pull rod 13 is released, and the first wheel frame 3 and the second wheel frame 4 can also keep moving away from each other.

[0037] Then, the rectangular box body 1 is placed on the bottom side of the electronic belt scale roller to be cleaned through the outer sleeve 10 until the arc groove 2 is embedded in the bottom side of the outer circle of the electronic belt scale roller. At this time, the inner guide tube 11 is pulled by the push-pull rod 13 to make the isosceles trapezoidal plate 12 release the isolation of the first triangular plate 8 and the second triangular plate 9, and the first wheel frame 3 and the second wheel frame 4 are close again under the tension of the tension spring 7. At this time, the first support wheel 5 is attached to one side of the outer circle of the electronic belt scale roller to be cleaned, and the second support wheel 6 is attached to the other side of the outer circle of the electronic belt scale roller to be cleaned. At this time, the inner guide tube 11 is located on the bottom side of the outer circle of the electronic belt scale roller to be cleaned; at this time, even if the outer sleeve 10 is loosened, the rectangular box body 1 can be clamped and fixed on the electronic belt scale roller to be cleaned under the action of the tension spring 7 without slipping.

[0038] As can be seen from the above, the first support wheel 5 and the second support wheel 6 can well clamp the electronic belt scale rollers of different diameters; then the cleaning liquid sprayed out through the spray hole 111 on the inner guide tube 11 cleans the outer cylindrical surface of the electronic belt scale roller; it can clean and maintain electronic belt scale rollers of different specifications and has a wide range of applications.

[0039] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
