Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric hot-rolling rollers, in particular to a non-woven fabric hot-rolling roller. Background Art

[0002] Hot rolling is the last web-forming technology in the production process of non-woven fabrics. It is a process to form fabrics after cooling and laying the yarns. The hot rolling roller is heated by some heating means, and then the processed products are heated and pressed into shape by rolling.

[0003] In the actual use of the hot rolling roller, after the non-woven fabric is hot-pressed, a small amount of fiber debris will stick to the outer wall of the roller body. If this continues for a long time, more debris will accumulate on the outer wall, which will affect the hot pressing process. For example, in the patent application entitled "A Non-woven Hot Rolling Roller" with the authorization publication number CN218711314U and the authorization publication date 2023-03-24, the motor-gearbox mechanism is started to drive the threaded rod to rotate, and the guide frame drives the cleaning scraper ring to move along the hot rolling roller body, and the soft brush ring in the cleaning scraper ring is used to fit the outer wall of the hot rolling roller body to clean the debris on the outer wall in multiple directions. After the cleaning is completed, the output shaft of the starting motor-gearbox mechanism is flipped and moved to reset and store on one side of the hot rolling roller body;

[0004] During the actual use of the above-mentioned device, the cleaning operation of the hot rolling roller body is achieved by driving the cleaning scraper ring to move horizontally. However, this method requires the hot rolling roller body to be in a non-working state, which affects the hot rolling efficiency of the non-woven fabric. After the hot rolling roller body is cleaned, the cleaning scraper ring needs to be frequently disassembled and cleaned, which is inconvenient to use.

[0005] So we proposed a nonwoven hot calender roller to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a non-woven fabric hot calendering roller to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-woven hot rolling roller, comprising a hot rolling roller body installed in a non-woven production workshop, support frames are installed on the left and right sides of the hot rolling roller body, a first rotating shaft, a second rotating shaft and a third rotating shaft are installed on the bearing between the lower ends of the left and right support frames, and the end of the second rotating shaft is connected to a motor, the motor drives the second rotating shaft to rotate, a mounting frame is fixed to the outer side of the middle of the first rotating shaft, and a cleaning brush is installed on the outer side of the mounting frame through a fastener, and the cleaning brush is used for cleaning impurities on the surface of the hot rolling roller body;

[0010] The ends of the first rotating shaft and the second rotating shaft are respectively installed with a driven groove wheel and a dial assembly, and the side of the third rotating shaft is installed with a flapping assembly, and the flapping assembly is used to flap the cleaning brush to flap the impurities on the cleaning brush to ensure the cleaning ability of the cleaning brush.

[0011] Furthermore, the dial assembly includes a dial body fixedly mounted on the left and right ends of the second rotating shaft, a locking arc disk and a round pin are fixedly mounted on the side of the dial body, and the dial assembly and the driven sheave form a sheave structure.

[0012] Through the above technical solution, the dial assembly can drive the driven groove wheel to rotate intermittently.

[0013] Furthermore, the cleaning brushes are distributed at equal angles about the center of the first rotating shaft, and the cleaning brushes are arranged in one-to-one correspondence with the radial grooves of the driven groove wheel, and the length of the cleaning brushes is greater than the length of the hot rolling roller body.

[0014] Through the above technical solution, multiple cleaning brushes can be used to reduce the cleaning frequency.

[0015] Furthermore, guide gears are fixedly sleeved on both sides of the left and right sides of the third rotating shaft, and the guide gears and the half gears form a meshing structure, and the half gears are fixedly sleeved on the outer middle part of the second rotating shaft, and the arc length of the tooth blocks on the half gears is smaller than the locking arc length of the locking arc disk.

[0016] Through the above technical solution, when the driven sheave is in a relatively static state under the restriction of the locking arc disk, the half gear can be driven to rotate.

[0017] Furthermore, the flapping assembly is composed of a fixed plate and a flapping plate, and the fixed plate is fixedly installed on the middle side of the third rotating shaft, and the flapping plate is rotatably installed on the side of the fixed plate.

[0018] Through the above technical solution, the third rotating shaft can drive the beating plate to beat the cleaning brush to beat off the impurities.

[0019] 3. Beneficial effects:

[0020] By adopting the technical solution provided by the utility model, compared with the prior art, the non-woven fabric hot rolling roller of the utility model can ensure the hot rolling efficiency while ensuring the hot rolling effect by arranging multiple groups of cleaning brushes under the hot rolling roller body, and reduce the cleaning frequency of the cleaning brushes. The specific contents are as follows:

[0021] (1) A mounting frame and a cleaning brush are provided, so that when the motor drives the second rotating shaft to rotate, the second rotating shaft uses the groove wheel structure between the dial body and the driven groove wheel to drive the mounting frame to rotate intermittently. After the mounting frame rotates, it drives the relatively clean cleaning brush to rotate to the bottom of the hot rolling roller body, so that during the hot rolling work of the hot rolling roller body on the non-woven fabric, under the relative position relationship, the debris on the hot rolling roller body can be scraped off by the cleaning brush, thereby ensuring the hot rolling efficiency and the hot rolling effect. Since the cleaning brush is installed on the mounting frame through a fastener, it is convenient to replace and clean the cleaning brush, and there are multiple groups of cleaning brushes distributed at equal angles, thereby reducing the cleaning frequency of the cleaning brush;

[0022] (2) A flapping assembly is provided so that when the locking arc disk restricts the rotation of the driven groove wheel, that is, when the cleaning brush on the mounting frame is in a relatively stationary state, the half gear can drive the third rotating shaft to rotate by means of the meshing action between the half gear and the guide gear. During the rotation of the third rotating shaft, the flapping plate is driven to flap the cleaning brush, thereby flapping off the impurities adhering to the cleaning brush, thereby ensuring the cleaning ability of the cleaning brush and further reducing the cleaning frequency.

[0034] After the motor connected to the end of the second rotating shaft 7 is started and the second rotating shaft 7 is driven to rotate, the second rotating shaft 7 uses the groove wheel structure between the dial body 81 and the driven groove wheel 6 to drive the mounting frame 4 to rotate intermittently. After the mounting frame 4 rotates, it drives the relatively clean cleaning brush 5 to rotate to the bottom of the hot rolling roller body 1. When the hot rolling roller body 1 is rotating to perform hot rolling on the non-woven fabric, under the relative position relationship, the debris on the hot rolling roller body 1 can be scraped off by the cleaning brush 5, so as to ensure the hot rolling efficiency and the hot rolling effect. Since the cleaning brush 5 is installed on the mounting frame 4 by fasteners, it is convenient to replace and clean the cleaning brush 5, and there are multiple groups of cleaning brushes 5 distributed at equal angles, so as to reduce the cleaning frequency of the cleaning brush 5.

[0035] The left and right sides of the third rotating shaft 10 are both fixedly sleeved with guide gears 11, and the guide gear 11 and the half gear 9 form a meshing structure, and the half gear 9 is fixedly sleeved on the middle outer side of the second rotating shaft 7, and the tooth block distribution arc length on the half gear 9 is smaller than the locking arc length of the locking arc disk 82; the flapping assembly 12 is composed of a fixed plate 121 and a flapping plate 122, and the fixed plate 121 is fixedly installed on the middle side of the third rotating shaft 10, and the flapping plate 122 is rotatably installed on the side of the fixed plate 121;

[0036] When the dial assembly 8 uses the locking arc plate 82 to limit the rotation of the driven groove wheel 6, that is, the cleaning brush 5 on the mounting bracket 4 is in a relatively static state, the half gear 9 uses the meshing action with the guide gear 11 to drive the third rotating shaft 10 to rotate. During the rotation of the third rotating shaft 10, the flapping plate 122 is driven to flap the cleaning brush 5, so as to flap off the impurities adhered to the cleaning brush 5, thereby ensuring the cleaning ability of the cleaning brush 5 and further reducing the cleaning frequency.

[0037] Working principle: When using the non-woven hot roll, Figure 1-5 As shown, during the hot rolling rotation of the hot rolling roller body 1 for hot rolling the non-woven fabric, the cleaning brush 5 attached to the hot rolling roller body 1 can scrape off the debris adhered to the surface of the hot rolling roller body 1 in a relative position. Then, when the cleaning brush 5 needs to be replaced, the motor connected to the end of the second rotating shaft 7 is started, and the second rotating shaft 7 uses the groove wheel structure between the dial body 81 and the driven groove wheel 6 to drive the relatively clean cleaning brush 5 to rotate to the bottom of the hot rolling roller body 1 to achieve replacement, thereby ensuring the hot rolling efficiency while ensuring the hot rolling effect, and reducing the cleaning frequency of the cleaning brush 5. During the process of the dial assembly 8 limiting the rotation of the driven groove wheel 6 by the locking arc disk 82, the beating plate 122 on the third rotating shaft 10 can be driven to beat the cleaning brush 5, and the impurities adhered to the cleaning brush 5 can be beaten off, thereby ensuring the cleaning ability of the cleaning brush 5 and further reducing the cleaning frequency.
