Description

Technical Field

[0001] The invention relates to the technical field of sound barriers on both sides of a road, and in particular to a width trimmer of a fiber-type sound barrier. Background Art

[0002] Now, both sides of expressways or railways need to be equipped with sound insulation devices, which are collectively referred to as sound barriers. At present, there are many types of sound barriers, the most common of which are ordinary metal sound barriers, aluminum alloy sound barriers, ordinary concrete sound barriers, GRC non-metallic sound barriers, photovoltaic sound barriers, etc.; among them, ordinary concrete sound barriers, with an average surface density of 195kg / m, are limited to use in roadbed sound barrier projects, do not generate static electricity, are heavy and difficult to install, and have a service life of ≥25 years; GRC non-metallic sound barriers, with an average surface density of 83kg / m, can be used in roadbed and bridge sound barrier projects, do not generate static electricity, are light and easy to install and bolted, and have a service life of ≥25 years. In recent years, a new type of ECP non-metallic sound barrier has appeared on the market, namely a fiber-type sound barrier, with an average surface density of 40-80kg / m, which can be used in roadbed and bridge sound barrier projects, does not generate static electricity, is light and easy to install, and has a service life of ≥30 years. The ECP non-metallic sound barrier is a high-pressure vacuum extruded fiber cement board, referred to as ECP board. In the process of producing ECP boards, the width of the initially formed dry blank board, as well as the dimensions of its raised and recessed parts, do not meet the standards, and the product quality cannot be guaranteed, resulting in a failure to install smoothly during assembly. Manual trimming using handheld edge grinders and other methods is time-consuming and labor-intensive, and it is difficult to ensure product quality, especially for dry blank boards with arc-shaped or other shaped cross-sections. Manual operation is more difficult and the standard size cannot be guaranteed.

[0003] In the prior art, the utility model patent with patent number 201921580579.8 discloses a production line for producing ECP boards, which belongs to the technical field of a complete set of production lines for ECP boards, including: a pretreatment system arranged in sequence according to the ECP board production process, which is used to modify solid waste slag to form modified slag; a mud preparation system, which is used to prepare mud using the modified slag as one of the raw materials; a plate forming system, which is used to produce the mud into ECP dry blank boards; a finishing system, which is used to finish the ECP dry blank boards to form ECP finished boards. However, in the finishing system of this scheme, an edge grinding machine is provided, but its structure is not described in detail, and there is no mention of how to grind the two sides of the dry blank board flush.

[0004] 202311683081.5 A rolling and integrated forming device for metal unit plates of sound barriers, relates to a rolling and integrated forming device for metal unit plates of sound barriers, including a base and a feeding mechanism that can assist workers to transfer the rolled metal unit plates; a conveying module, a rolling module, a cutting assembly and a shaping mold are arranged on the base; the shaping mold is fixedly installed on the top of the base, and is used to assist the metal unit plates in rolling to form a shaping structure; the rolling module can roll and shape the metal unit plates; the conveying module can drive the metal unit plates to move on the shaping mold; the cutting assembly can cut the metal raw materials into equal parts. The present invention mainly drives the slot rod to swing by a reciprocating motor, pushes the push plate to the left, pushes the metal unit plate onto the hook column, and lowers the metal unit plate by resetting the hook column, without the need for workers to move it down, which can reduce the physical exertion of workers. However, this scheme also does not explain which method is used to machine the dry blank plate in the machining system.

[0005] None of the above-mentioned existing technologies solves the problem of how to make the dry blank board reach the standard size, and the product quality cannot be guaranteed, which affects the subsequent assembly. In particular, for dry blank boards with arc-shaped or other shapes in cross-section, when processing them by handheld grinders or the like, the production efficiency is low and it is even more difficult to ensure the size of the dry blank board. Therefore, in order to solve this problem, there is an urgent need for a width trimming machine for fiber-type sound barriers that can continuously and quickly process dry blank boards and reach standard sizes. Once there is a large deviation in size, assembly becomes a big problem. Summary of the invention

Different molds produce different board shapes; the third step: kiln curing, the extruded board is sent to the curing kiln for the first curing; the fourth step: cutting and processing, processing after leaving the kiln, cutting and grinding and polishing according to the ordered size; the fifth step: high temperature curing, entering the high temperature and high pressure kiln for secondary curing, so that the cement undergoes a chemical reaction, further increasing the strength and toughness of the board.

[0033] In the process of producing fiber-reinforced non-metallic sound barriers, that is, the grinding and polishing according to the set size in the above-mentioned fourth process; first, the positions of the first positioning plate and the third positioning plate in the positioning mechanism 5 in the vertical direction are set according to the requirements of different models, and the positions of the second positioning plate and the fourth positioning plate in the vertical direction are set, and the power device is working, the dry blank plate 6 is located on the conveyor belt between the first wheel group and the limiting group, and runs along the conveying direction from the back to the front with the conveyor belt. The groove portion 602 of the dry blank plate 6 is against multiple limiting plates 2041, and multiple first guide wheels 2031 are all against the raised portion 601 of the dry blank plate 6, which limits the left and right directions of the dry blank plate 6 to prevent deviation. In the process of conveying the dry blank plate 6, the first guide wheel 2031 and the limiting plate 2041 play a guiding and limiting role, so that the dry blank plate 6 always keeps the horizontal direction and moves with the conveyor belt, avoiding the deviation of the dry blank plate 6 during the conveying process and affecting the subsequent finishing effect, ensuring smooth feeding, and ensuring that the dry blank plate 6 does not deviate during feeding. Then, when the dry blank plate 6 runs between the convex side grinding mechanism 3 and the concave side grinding mechanism 4, the first convex side screw, the second convex side screw, the third convex side screw, and the fourth convex side screw are adjusted to adjust the positions between the first convex side grinding knife, the second convex side grinding knife, the third convex side grinding knife, and the fourth convex side grinding knife and the raised portion 601 of the dry blank plate 6, so as to facilitate the grinding of the outer end surface of the raised portion 601 of the dry blank plate 6 to meet the use requirements; by adjusting the first concave side screw, the second concave side screw, the third convex side screw, and the fourth convex side screw, the positions between the first convex side grinding knife, the second convex side grinding knife, the third convex side grinding knife, and the fourth convex side grinding knife The side screw, the third concave side screw and the fourth concave side screw are used to adjust the position between the first concave side grinding knife, the second concave side grinding knife, the third concave side grinding knife and the fourth concave side grinding knife and the groove portion 602 of the dry blank plate 6, so as to facilitate the grinding of the outer end surface of the groove portion 602 of the dry blank plate 6 to meet the use requirements. In the above process, the convex side grinding mechanism 3 and the concave side grinding mechanism 4 both work at the same time, and both sides of the dry blank plate 6 are trimmed at the same time, which is beneficial to the smooth transportation of the dry blank plate 6 along the conveying direction.Finally, when the feeding mechanism 2 sends the front end of the dry blank plate 6 to the positioning mechanism 5, the pressing wheel 2061 on the pressing plate 206 on the feeding mechanism 2 is still pressed on the rear end of the dry blank plate 6; in this process, the convex side grinding mechanism 3 and the concave side grinding mechanism 4 simultaneously trim the raised portion 601 and the groove portion 602 of the dry blank plate 6; by adjusting the first convex side inclined screw, the first convex side inclined seat 305 is close to or away from the dry blank plate 6, so that the first convex side inclined grinding knife 3051 driven by the fifth convex side driving mechanism is close to or away from the dry blank plate 6, and when the first convex side inclined grinding knife 3051 and the raised portion 601 of the dry blank plate 6 are in the set position, the lower edge of the end of the raised portion 601 of the dry blank plate 6 is ground to meet the requirements; the position of the convex side support frame 306 in the left and right directions is adjusted by adjusting the second convex side inclined screw, and the position of the convex side support frame 306 in the left and right directions is adjusted by adjusting the third convex side The lead screw is tilted to adjust the position of the sixth convex side driving mechanism in the vertical direction. After the second convex side tilted grinding knife 3061 and the raised portion 601 of the dry blank plate 6 reach the set position, the upper edge of the raised portion 601 end of the dry blank plate 6 is grinded to meet the requirements; the first concave side tilted grinding knife 4051 grinds the lower edge of the groove portion 602 of the dry blank plate 6, and the second concave side tilted grinding knife 4061 grinds the upper edge of the groove portion 602 of the dry blank plate 6; the fifth concave side grinding knife 4071 grinds the upper groove surface of the groove portion 602 on the dry blank plate 6, and the sixth concave side grinding knife 4072 grinds the lower groove surface of the groove portion 602 on the dry blank plate 6; to ensure that the groove portion 602 of the dry blank plate 6 is quickly and comprehensively ground to meet the required requirements, ensure product quality, improve production efficiency, and facilitate subsequent installation.

[0034] The present invention guides and limits the dry blank plate 6 by installing a plurality of first guide wheels 2031 and a limiting plate 2041 which are arranged at intervals along the length direction and guide and limit the dry blank plate 6 on the opposite sides of the first material guide seat 203 and the second material guide seat 204, thereby preventing the dry blank plate 6 from running off and continuously and smoothly conveying the dry blank plate 6 along the conveying direction; by installing a column 205 on the base frame 1, and installing a pressing plate 206 which is driven by a feeding drive mechanism to move along the vertical direction on each of the columns 205, so that a plurality of pressing wheels 2061 at the bottom of the pressing plate 206 are equidistantly distributed along the length direction of the pressing plate 206 and press on the corresponding dry blank plate 6, so as to limit the dry blank plate 6 to be trimmed and prevent the dry blank plate 6 from being staggered during grinding.
