Description

Technical Field

[0001] The utility model relates to the technical field of aerogel felt preparation, in particular to a device for scraping glue on the lower surface of a gel felt. Background Art

[0002] When producing aerogel mats on a gel production line, the fiber mat is combined with the glue and gelled on a conveyor to produce a wet gel mat. During the gelling process, due to the action of gravity, the glue flows vertically downward to the bottom of the wet gel mat, which can make the top surface of the gel mat smooth, good appearance, and uniform gelling. However, there will be excess glue residue at the bottom of the gel mat, resulting in an uneven gel at the bottom, which needs to be scraped off.

[0003] In the prior art, the following methods are usually used:

[0004] (1) Before gelling, the glue is scraped by roller pressing. The problem with this method is that excess glue will be squeezed out, and the ungelled glue will still move under the action of gravity, resulting in residual gel blocks at the bottom.

[0005] (2) After the gel dries, the excess aerogel is removed by manual cutting, scraping, etc., which has high labor costs;

[0006] In summary, how to effectively scrape off excess gel at the bottom without destroying the aerogel felt structure to ensure the flatness and uniformity of the gel felt product has become a key technical challenge.

[0007] Based on this, it is necessary to study a scraping device for the lower surface of gel felt. Utility Model Content

[0013] The scraper mechanism is rotatably arranged on the frame and rotated counterclockwise by the driving member. The scraper mechanism is located between the first conveyor belt mechanism and the second conveyor belt mechanism and below the conveying surface, so that the scraper mechanism scrapes glue on the lower surface of the gel felt between the first conveyor belt mechanism and the second conveyor belt mechanism.

[0014] Furthermore, the scraper mechanism includes a rotating shaft, a blade holder and a scraper;

[0015] The rotating shaft is rotatably arranged on the frame and is transmission-connected to the driving member;

[0016] The tool holder is a rectangular tool holder, which is fixedly sleeved on the rotating shaft. A scraper is fixed on the tool holder, and the scraper is located between the first rolling roller and the second rolling roller.

[0017] Furthermore, the first laminating roller and the second laminating roller each include a central shaft and a roller; both ends of the central shaft are arranged on a frame, and the roller is rotatably sleeved on the central shaft.

[0018] Furthermore, the frame is provided with a vertically oriented first adjustment strip hole corresponding to the position of the central axis.

DETAILED DESCRIPTION

[0034] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0035] This embodiment aims to provide a gel felt bottom surface scraping device, which is mainly used to scrape the bottom surface of the gel felt sheet after gelation, and addresses the problem of how to effectively scrape off excess gel on the bottom without destroying the aerogel felt structure.

[0036] A gel felt lower surface scraping device, such as Figure 1 and Figure 2 , including a frame 1, a first conveyor belt mechanism 2, a second conveyor belt mechanism 3, a first laminating roller 4, a second laminating roller 5 and a scraper mechanism 6.

[0037] The first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 both convey horizontally from left to right. The second conveyor belt mechanism 3 is arranged at the right end of the first conveyor mechanism. The conveying surfaces of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 are on the same plane. The left and right directions in this embodiment can be referred to Figure 2 In this embodiment, two groups of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 are arranged side by side to form two scraping processing lines. The specific structure and working principle of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 adopt the existing technology and will not be repeated here.

[0038] Both side end faces of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 are bolted to the frame 1, and the first rolling roller 4 and the second rolling roller 5 are rotatably set on the frame 1. In this embodiment, the first rolling roller 4 and the second rolling roller 5 both include a central axis 401 and a roller 402; both ends of the central axis 401 are fixedly set on the frame 1, and the roller 402 is rotatably mounted on the central axis 401.

[0039] like Figure 2-4 The first laminating roller 4 and the second laminating roller 5 are respectively located above the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3, and form a laminating gap with the conveying surface of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 respectively. The height of the laminating gap is less than the thickness of the gel felt 10. When the gel felt 10 passes through the laminating gap, it can be applied with upper pressure by the first laminating roller 4 and the second laminating roller 5 to facilitate the scraping of glue on its lower end surface. Since the gel blocks on the lower surface of the gel felt 10 adhere to the felt body, the gel and the felt body have a certain elasticity, so it is necessary to apply pressure to their upper surfaces to facilitate the scraping of glue on the lower surface of the gel felt 10. In this embodiment, the first laminating roller 4 and the second laminating roller 5 are both driven rotations. When the gel felt 10 contacts them, the corresponding laminating rollers rotate accordingly to facilitate the smooth passage of the gel felt 10 through the laminating gap.

[0040] like Figure 2-4The scraper mechanism 6 is rotatably mounted on the frame 1 and rotates counterclockwise from right to left via a drive member 9. The scraper mechanism 6 is located between the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 and below the conveying surface. In this embodiment, the scraper mechanism 6 includes a rotating shaft 601, a blade holder 602, and a scraper 603. Both ends of the rotating shaft 601 are rotatably mounted on the frame 1. One end of the rotating shaft 601 is connected to a drive member 9, which is a servo motor. The blade holder 602 is a rectangular blade holder 602, which is fixedly mounted on the rotating shaft 601. A scraper 603 is fixed to the upper portion of the blade holder 602. When the rotating shaft 601 rotates, the scraper 603 rotates accordingly and performs a glue scraping process on the lower surface of the gel felt 10.

[0041] When the cutting edge of the scraper 603 is rotated to its highest position, its cutting edge is 2-10 mm above the conveying surface. In this embodiment, the distance between the first laminating roller 4 and the second laminating roller 5 is 120 mm, and the scraper 603 is centered between the first laminating roller 4 and the second laminating roller 5, that is, the scraper 603 is 60 mm away from each laminating roller. In other embodiments, the height of the scraper mechanism 3 and the distance between the first laminating roller 4 and the second laminating roller 5 can be adjusted as needed to adjust the degree of bending of the gel felt 10. For example, if a thick gel felt sheet is not easy to bend, the distance between the two rollers can be increased and the height of the scraper 603 can be lowered to ensure that the scraper 603 in the middle pushes the gel felt 10 upward to cause it to bend, so that the scraper mechanism 6 can perform a glue treatment on the lower surface of the gel felt 10 between the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3.

[0042] Furthermore, in order to adapt to gel felt 10 of different thicknesses, as Figure 5 and Figure 6 The frame 1 is provided with a vertically oriented first adjustment strip hole 101 corresponding to the position of the central axis 401. Both ends of the central axis 401 are detachably connected to the frame 1 through nuts and other connecting parts and the corresponding first adjustment strip holes 101 and can be adjusted up and down; the first rolling roller 4 and the second rolling roller 5 both adopt the above structure, so that the first rolling roller 4 and the second rolling roller 5 can be adjusted up and down, thereby realizing the adjustment of the rolling gap, and then realizing the adaptation of gel felt 10 of different thicknesses and the adjustment of the rolling pressure.

[0043] Furthermore, in order to clean the scraper mechanism 6 and prevent the excess glue scraped from adhering to the scraper mechanism 6, thereby ensuring the quality of the scraped glue, a cleaning component 7 is also included; the cleaning component 7 includes a cleaning frame 701 and a cleaning brush 702; both ends of the cleaning frame 701 are fixed on the frame 1 and are located below the scraper mechanism 6, and the cleaning brush 702 is vertically fixed upward on the cleaning frame 701 and extends to the range of the scraper mechanism 6, so that the top of the cleaning brush 702 contacts the scraper mechanism 6. When the scraper mechanism 6 rotates, the cleaning brush 702 forms a cleaning effect on the scraper mechanism 6, sweeping away the glue adhering to the scraper mechanism 6.

[0044] Furthermore, in order to be able to adjust the cleaning force and range of the scraper mechanism 6 by the cleaning mechanism, as shown in FIG. Figure 4 A vertical second adjustment strip hole 102 corresponding to the position of the cleaning frame 701 is opened on the frame 1. The cleaning frame 701 is detachably connected to the frame 1 through connecting parts such as a bolt kit and the corresponding second adjustment strip hole 102, so that the cleaning frame 701 can be adjusted up and down, thereby adjusting the cleaning force and cleaning range of the cleaning brush 702 on the scraper mechanism 6.

[0045] Furthermore, in order to prevent the wet gel from being brushed off from splashing onto the conveyor belt, as Figure 2 A baffle 8 is arranged between the scraper mechanism 6 and the first conveyor belt mechanism 2 and between the scraper mechanism 6 and the second conveyor belt mechanism 3. Both ends of the baffle 8 are bolted to the frame 1.
