Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically a cleaning device for a trolley side net. Background Technology

[0002] The manufacturing process of the trolley side mesh includes the following steps: cutting the mesh material and the surrounding profile frame according to the design requirements, placing the mesh material inside the profile frame for precise positioning, performing continuous or spot welding along the contact points between the profile and the mesh, removing the welding slag, grinding the weld seam, and cleaning the surface. Although the welding process can effectively fix the side mesh structure, it will also generate a variety of contaminants on the side mesh surface, which seriously affects product quality and subsequent use.

[0003] The welding electrode coating and shielding gas used in the welding process produce welding slag, especially at weld intersections and in areas with dense mesh, where slag tends to accumulate and is difficult to remove. The presence of welding slag affects the flatness and cleanliness of the edge mesh.

[0004] Secondly, high-temperature welding causes oxidation on the metal surface, forming an oxide scale. This oxide scale not only affects the appearance but also reduces the material's corrosion resistance, making it particularly susceptible to further rusting in humid environments. The thermal cycling during welding significantly increases the surface roughness of the weld and its surrounding area, creating conditions for the adhesion of bacteria and dirt.

[0005] Currently, post-weld cleaning of most trolley edge mesh relies primarily on manual grinding with a hand-held grinder. This method has the following drawbacks: First, manual operation is labor-intensive, and prolonged grinding can easily cause operator fatigue, affecting cleaning efficiency and quality. Second, manual operation is greatly affected by human factors, making it difficult to ensure consistent cleaning at each weld and mesh intersection, easily leading to inadequate cleaning in certain areas or over-grinding, resulting in product quality fluctuations. Third, in densely meshed areas and corners, the size and shape of the grinding tools limit cleaning difficulty and efficiency, and some weld slag and oxide scale cannot be completely removed. Summary of the Invention

[0006] The technical problem to be solved by this application is to overcome the existing defects and provide a cleaning device for the side net of a trolley, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a cleaning device for the side net of a trolley, comprising a support frame, a movable component mounted on the support frame, the movable component comprising a longitudinal movable group and a transverse movable group, the transverse movable group being mounted on the longitudinal movable group, the movable end of the transverse movable group being connected to a connecting side plate, the connecting side plate being connected to a grinding mounting frame via fasteners, the grinding mounting frame being provided with grinding components; a bearing frame is provided below the movable component, the bearing frame being provided with a side net holder for fixing the side net of the trolley, the side net holder being detachably connected to the bearing frame to facilitate replacement between side nets of different specifications.

[0008] As a preferred technical solution of this application, the support frame includes side supports and a middle support plate, and side supports are provided on both sides of the lower surface of the middle support plate.

[0009] As a preferred technical solution of this application, the middle support plate is provided with guard plates on both sides, and a cavity for installing the longitudinal moving assembly is provided between the guard plates.

[0010] As a preferred embodiment of this application, the lateral moving group is mounted on a carrier plate on the longitudinal moving group, and the carrier plate is located at the movable end of the longitudinal moving group.

[0011] As a preferred technical solution of this application, a groove is provided on the lower surface of the edge mesh card holder, and a strong magnet is embedded in the groove.

[0012] As a preferred technical solution of this application, the edge net card holder is arranged diagonally and has an empty slot for placing the edge net.

[0013] As a preferred technical solution of this application, the support frame is located on the upper surface of the workbench, and the two are connected by fasteners.

[0014] As a preferred technical solution of this application, the grinding component is a replaceable grinding wheel, which is installed on the grinding mounting frame through a quick-release structure.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This application realizes the automated and precise movement of the grinding part in a two-dimensional plane by adopting a bidirectional electric slide mechanism with longitudinal and transverse movement groups, thereby improving cleaning efficiency. The grinding part can cover all areas of the edge mesh according to the preset program, including areas that are difficult to handle by traditional methods, such as mesh gaps and corners, effectively eliminating cleaning blind spots and completely solving the problem of inconsistent cleaning quality caused by manual operation. It also significantly improves the removal rate of contaminants such as welding spatter, welding slag, and oxide scale. The programmed control of the electric slide avoids the arbitrariness of manual operation and ensures the continuity and consistency of cleaning operations.

[0016] The edge net holder is attached to the support frame by strong magnets, and the operator can adjust the position of the holder arbitrarily according to the size requirements of different specifications of edge nets. This allows the same machine to process edge nets of various sizes for trolleys, significantly improving equipment utilization. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0023] Please see Figure 1-4 This application provides a technical solution: a cleaning device for the side net of a trolley, wherein the workbench 1 is composed of a profile and a steel plate disposed on the upper surface of the profile, and the support frame 2 is fastened to the upper surface of the workbench 1 by four M12 bolts to ensure structural stability.

[0024] The lower surface of the workbench 1 is also equipped with casters, which facilitates the free movement of the workbench 1 and improves the freedom of use. At the same time, adjustable support feet are also provided near one side of the casters to facilitate the adjustment of the stability of the workbench 1.

[0025] The support frame 2 includes two side supports 2a and a middle support plate 2b. The middle support plate 2b is a rectangular steel plate, and the two side supports 2a are fixed on both sides of the lower surface of the middle support plate 2b respectively. Each side support 2a is welded together from two columns and a base.

[0026] The side support 2a and the intermediate support plate 2b are welded together using continuous fillet welds to ensure a strong connection and good seismic performance. Non-destructive testing is performed on the weld area to ensure welding quality and meet the structural reliability requirements under long-term loads.

[0027] A guard plate 10 is provided on each side of the intermediate support plate 2b, and the cavity width formed between the two guard plates 10 is used to accommodate the longitudinal moving group 5.

[0028] The guard plate 10 is arranged longitudinally along both sides of the intermediate support plate 2b, and its inner side forms a guide cavity to accommodate and guide the smooth sliding of the longitudinal moving group 5. This prevents lateral deviation or derailment during operation and improves operational accuracy and safety.

[0029] Both the longitudinal movement group 5 and the transverse movement group 7 employ electric slide mechanisms, including stepper motors, ball screw transmission systems, and precision linear guides. The effective stroke of the slide is 400mm. The stepper motor is connected to the ball screw via a coupling to achieve precise position control. The linear guide adopts a double-rail design to ensure smooth movement. The electric slide is installed in the cavity between the guard plates 10 of the intermediate support plate 2b, and the movable end of the slider in the linear guide is connected to a carrier plate 11.

[0030] The lateral moving assembly 7 is mounted on the carrying plate 11, and the movable end of the lateral moving assembly 7 is connected to the connecting side plate 8.

[0031] The connecting side plate 8 is connected to the grinding mounting frame 9 by two M8 bolts. The connecting side plate 8 is provided with multiple sets of mounting holes to enable fine adjustment of the grinding mounting frame 9, which facilitates precise alignment of different workpieces. The grinding part 6 adopts a replaceable grinding wheel and is installed on the grinding mounting frame 9.

[0032] The support frame 4 is located below the movable component and adopts a frame structure, consisting of 4 uprights and a base plate. Two side net holders 3 are installed on the base plate, arranged diagonally to accommodate side nets for trolleys of different sizes.

[0033] Each edge mesh holder 3 is a square block structure with a groove 20mm deep inside. After the edge mesh to be polished is installed on the trolley, the edge mesh to be polished is 3cm higher than the groove.

[0034] The square block structure of the edge net holder 3 has a rectangular groove for placing the edge net. Wear-resistant rubber or nylon pads are embedded in the groove, which can protect the surface of the edge net from scratches and can also accommodate edge nets with slight size deviations, thus improving clamping compatibility.

[0035] Two strong magnets are embedded in the lower surface of the edge net holder 3, which can be firmly fixed on the support frame 4. The operator can adjust the position of the edge net holder 3 arbitrarily according to the size requirements of different specifications of edge nets.

[0036] The strong magnets are made of neodymium iron boron permanent magnets, which facilitates the loading and unloading of the side netting.

[0037] In use: First, select the appropriate side mesh holder 3 according to the size and specifications of the side mesh to be cleaned, and install it in the corresponding position on the support frame 4. Then, place the trolley side mesh on the side mesh holder 3 and fix it in place by the attraction force of the strong magnet. After starting the equipment, the longitudinal moving group 5 and the transverse moving group 7 move according to the preset program, driving the grinding parts 6 to perform cleaning operations on the surface of the side mesh. Driven by the moving components, the grinding parts 6 can cover all areas of the side mesh. By using different sizes of grinding wheels in combination, a complete process from coarse cleaning to fine polishing can be achieved.
