Description

Technical Field

[0001] The utility model relates to a surface grinding and plastic dipping mechanism for municipal guardrail processing, in particular to a surface grinding and plastic dipping mechanism for municipal guardrail processing, belonging to the technical field of guardrail processing. Background Art

[0002] Guardrails are mainly used for the protection and protection of personal safety and equipment facilities in residential, highway, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. Guardrails are usually made of steel, such as stainless steel, round steel pipes, square steel pipes or corrugated steel plates. In recent years, aluminum alloy plug-in and assembled guardrails have also become more popular. In the process of processing the guardrail, many burrs will form on the surface of the guardrail raw material, and the burrs need to be polished to facilitate the processing of the raw material later. However, when grinding and removing the burrs on the surface of the raw material, the operator usually takes a handheld grinder to grind the burrs on the surface of the raw material little by little. However, when the operator manually uses a handheld grinder to grind the surface of the raw material, it is not only inefficient, but the waste generated during grinding will also cause harm to the operator.

[0003] Therefore, the existing method of grinding guardrails usually adopts a grinding machine for grinding, and the rapid grinding effect of the guardrail is achieved through the cooperation between the transmission equipment and the grinding equipment.

[0004] When the second processing method is adopted, a staff member is often required to discharge the material, and the staff member is required to transport the guardrails one by one, especially when the quantity is large. This method reduces the processing efficiency to a certain extent and requires the cooperation of several staff members. The staff members keep putting in materials, which also increases the labor cost. Usually, the guardrail can only be polished on the top and bottom, and the side polishing of the guardrail needs to be put into the equipment specially used for polishing the side, so that the guardrail polishing needs to be carried out by several devices. In addition, the grinding roller will cause its exterior to degrade with long-term use, and the contact with the plate is insufficient, which will reduce the effect of the grinding roller, thereby reducing the processing efficiency of the guardrail. Therefore, the processing efficiency of the guardrail needs to be improved. In view of this, it is urgent to improve the surface polishing and plastic dipping device for guardrail processing to solve the above-mentioned problems. Utility Model Content

[0056] Embodiment three:

[0057] In this embodiment, Figure 9-12 As shown, the grinding part 3 includes an upper grinding roller 301 and a side grinding roller 302 arranged on the frame 101, and a linkage mechanism 303 for linking the upper grinding roller 301 and the side grinding roller 302. The linkage mechanism 303 includes a stepper motor 3030 fixedly mounted on the side wall of the frame 101, a rotating shaft 3031 mounted on the output shaft of the stepper motor 3030 through a coupling, a second transmission wheel 3036 fixedly mounted on the outside of the rotating shaft 3031, and a transmission bevel gear 3032.

[0059] In this embodiment, Fig. 9 and Fig.10As shown, the upper and lower ends of the four side grinding rollers 302 are all equipped with third transmission wheels 3037, and the third transmission wheel 3037 close to the linkage mechanism 303 and the second transmission wheel 3036 and the two adjacent third transmission wheels 3037 are all connected by second transmission belts 3038. A transverse plate 3039 for installing the four side grinding rollers 302 is installed on the inner wall of the frame 101 close to the linkage mechanism 303, and the four side grinding rollers 302 are connected to the transverse plate 3039 through bearings. A movable opening is provided inside the frame 101 so that the second transmission belt 2038 at the front can be driven. A limit seat for limiting the rotating shaft 3031 is installed outside the frame 101. The rotating shaft 3031 is connected to the limit seat through a bearing. The three upper grinding rollers 301 are all connected to the inside of the frame 101 through bearings to ensure stable rotation and stable grinding.

[0060] In this embodiment, Fig.12 As shown, the four side grinding rollers 302 are provided with mounting holes 3021 inside, and the outer surface of the grinding roller 302 is detachably mounted with a brush 304 through the cooperation of bolts and the mounting holes 3021, which can perform diversified grinding on the plate and improve the grinding quality and efficiency of the plate.

[0061] When this embodiment is in use, the plates are transported in sequence through the feeding part 2, and the stepping motor 3030 is started to drive the rotating shaft 3031, the transmission bevel gear 3032 and the second transmission wheel 3036 to rotate. The transmission bevel gear 3032 rotates and engages with the driven bevel gear 3033 to drive the front upper grinding roller 301. Through the installation of the first transmission wheel 3034 and the first transmission belt 3035, and the linkage cooperation of the second transmission wheel 3036, the third transmission wheel 3037 and the second transmission belt 2038, the four side grinding rollers 302 and the three upper grinding rollers 301 rotate at the same time to grind the plates, and at the same time, the coating device 103 sprays the coating on the grinded plates to realize the plastic coating process, thereby further improving the plate processing efficiency.

[0062] In this embodiment, Fig.13 and Fig.14As shown, in order to better grind the plate and adjust the grinding depth, a tensioning structure 305 is arranged inside the upper grinding roller 301; the tensioning structure 305 includes two symmetrically distributed slides 3051, a first grinding plate 3052 and a second grinding plate 3053 distributed up and down, a double-axis cylinder 3054 installed inside the upper grinding roller 301 by bolts and connected to the opposite sides of the two slides 3051, and an articulated seat 3056 fixedly connected to the upper and lower sides of the two slides 3051 and the opposite sides of the first grinding plate 3052 and the second grinding plate 3053, and a support rod 3055 is installed between the articulated seat 3056 on the first grinding plate 3052 and the second grinding plate 3053 and the articulated seat 3056 on the upper and lower sides of the two slides 3051.

[0063] The upper grinding roller 301 is fixedly installed with a guide rod 3057 penetrating the two slide seats 3051. There are two guide rods 3057, and the two guide rods 3057 are symmetrically arranged, so that the two slide seats 3051 can be linearly displaced to ensure the stable adjustment of the first grinding plate 3052 and the second grinding plate 3053.

[0064] When this embodiment is in use, the two slide seats 3051 are driven to move by the dual-axis cylinder 3054, so that the first grinding plate 3052 and the second grinding plate 3053 can be expanded and retracted, which can not only adjust the grinding depth of the plate, but also avoid the grinding roller being unable to effectively fit the plate after long-term use, thereby eliminating the need to frequently replace the grinding roller, greatly improving the effect and practicality of guardrail surface grinding.

[0065] In addition, the expansion and contraction of the first grinding plate 3052 and the second grinding plate 3053 can also be used to cover grinding brushes with different functions, for example, the brush 304 is covered on the outer surface of the upper grinding roller 30301 and fixed by the expansion structure 305, thereby greatly improving the installation and practicality of grinding brushes with different functions. The first grinding plate 3052 and the second grinding plate 3053 are both semicircular arcs.

[0066] like Figure 1-Figure 12As shown, the principle of the surface grinding and plastic dipping device for municipal guardrail processing provided in this embodiment is as follows: when in use, the guardrail plate to be processed is placed in the discharge box 2033, and the belt conveyor 2022 is lifted and lowered to a height suitable for the grinding part 3 by the hydraulic cylinder 2013, and the intermittent motor 2035 is started to drive the transmission gear 2036 to engage with the driven gear 2037 to drive the shaft 20371, and the shaft 20371 drives the crank 2038 and the connecting plate 2039 to move. At this time, the connecting plate 2039 extends back and forth in the conveying box 2032. When the connecting plate 2039 is moved back and forth, the connecting plate 2039 is moved back and forth. When the lever 2039 moves back and forth, it pushes a plate onto the belt conveyor 2022, and the plate at the bottom of the stack will drop and take over the position of the plate that has been pushed out, and so on, so that the plates in the conveying box 2032 are transported to the belt conveyor 2022 in an orderly and rapid manner, and then the upper grinding roller 301 and the side grinding roller 302 are rotated through the linkage mechanism 303 to grind the plates, and at the same time, the paint is sprayed onto the grinded plates through the paint device 103 to realize the plastic coating process, thereby further improving the plate processing efficiency.

[0067] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".
