Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing equipment technology, specifically to a paper scraping device. Background Technology

[0002] Cigarette forming paper plays a crucial role in cigarette manufacturing. It not only determines the appearance, texture, and structural integrity of cigarettes but also directly affects the smoking experience and the filtration efficiency of harmful substances. Cigarette forming paper mainly includes cigarette paper, filter rod forming paper, and tipping paper (i.e., cigarette tipping paper). These papers typically have a smooth surface and weak adhesive absorption, which may affect the adhesive application effect of the filter rod.

[0003] To improve paper performance, we can increase the surface roughness of the paper. This process, called roughening, strengthens the bond between fibers and fillers, improves abrasion resistance, and enhances the appearance and texture of the filter rod. These improvements significantly enhance the overall performance and stability of the filter rod. Therefore, we recommend introducing a scraping device to roughen the surface of the formed paper to optimize its performance, ensuring the quality of cigarette products and the user experience.

[0030] In a preferred embodiment of this utility model, the scraping mechanism 1 is further fixedly installed on the frame of the forming machine between the forming paper receiving device and the gluing device. The dust removal mechanism 2 is located below the scraping mechanism 1. The forming paper 6 is guided into the scraping mechanism 1 by multiple guide rollers 3, scraped, and then glued upwards through the guide plate 4, the guide acceleration wheel 5, and the guide rollers 3.

[0031] In a preferred embodiment of the present invention, the housing assembly 101 is further composed of a front door 10101, a handle 10102, a baffle 10103, a right side panel 10104, an upper cover 10105, a paper conveying channel 10106, a left side panel 10107, and a lower base plate 10108. The handle 10102 is located in the middle of one side of the front door 10101. The front door 10101 is hinged to the right side panel 10104. The upper cover 10105 and the left side panel 10107 are both provided with paper conveying channels 10106.

[0032] In a preferred embodiment of the present invention, the scraper holder assembly 108 further includes a brushing blade 10801, two V-blocks 10802, a mounting base 10803, a locking plate 10805, four guide posts 10807, and a mounting cover 10808.

V-blocks 10802 are fitted between adjacent guide posts 10807, and locking plates 10805 are fitted between the four guide posts 10807. Mounting base 10803 is located between locking plates 10805 and V-blocks 10802. Locking screws are provided at both ends of guide posts 10807. V-blocks 10802, locking plates 10805, and four guide posts 10807 are all connected. A locking switch mechanism is provided between the locking blade plate 10805 and the mounting base 10803, which are fastened together by locking screws. The buffing blade 10801 is clamped and fixed between the V-block 10802 and the mounting base 10803 by the locking switch mechanism. The mounting cover 10808 is fastened to the mounting base 10803 by screws. The locking switch mechanism is located inside the mounting cover 10808. The internal shape of the mounting cover 10808 matches the contour of the locking blade plate 10805. The locking blade plate 10805 is slidably connected inside the mounting cover 10808.

[0034] Specifically, such as Figure 4-5As shown, by turning the adjusting screw 10806 counterclockwise, the wedge 10804 moves towards the end closer to the support 107, and the guide post 10807 extends towards the end closer to the V-block 10802. The diamond-shaped groove formed by the V-block 10802 and the mounting base 10803 is larger than the installation position of the buffing knife 10801. The buffing knife 10801 is placed into the groove. At the same time, the locking plate 10805 is pressed against the mounting base 10803. Turning the adjusting screw 10806 clockwise, the wedge 10804 moves towards the end closer to the adjusting screw 10807. When one end of knob 806 moves, guide post 10807 extends towards the end near locking plate 10805. The diamond-shaped groove formed by the V-block 10802 and mounting base 10803 fixes the brushing knife 10801. The brushing knife 10801 is tightened or loosened by rotating the adjusting screw 10806 of the scraper seat assembly 108. The guide post 10807 is moved back and forth by the left and right displacement of wedge 10804 on the adjusting screw 10806, so as to loosen and lock the brushing knife 10801, making it convenient for operators to disassemble and assemble the brushing knife 10801.

The top inclined surface of the wedge 10804 is in contact with the bottom inclined surface of the locking plate 10805.

[0036] In a preferred embodiment of this utility model, the dust removal mechanism 2 further includes a filter barrel 201, a negative pressure inlet 202, and a suction pipe 203. One end of the suction pipe 203 is fixedly installed in the middle of the lower base plate 10108, and the other end is connected to the filter barrel 201. The negative pressure inlet 202 is located in the middle of the suction pipe 203. One end of the suction pipe 203 is fixedly installed on the lower base plate 10108 of the cover assembly 101, and the other end is connected to the filter barrel 201. The negative pressure inlet 202 is fixed in the middle. The negative pressure enters the suction pipe 203 from the negative pressure inlet 202 and passes into the paper scraping mechanism 1 to adsorb the dust on the formed paper 6 and enter the filter barrel 201 through the suction pipe 203.

[0037] The working principle of this paper scraping device is as follows: After being guided by the paper guide roller 3, the formed paper 6 enters through the U-shaped groove of the left side plate 10107 of the cover assembly 101 and is conveyed upward under the guidance of the paper guide roller 3. The servo motor 102 drives the slide table 103 to move, which in turn moves the support 107 and the brushing knife 10801 fixed to the support 107 to the left and right, so that the brushing knife 10801 is adjusted to be close to the side of the formed paper 6. The brushing knife 10801 scrapes the formed paper 6 conveyed upward. The dust removal mechanism 2 adsorbs the dust generated by the paper scraping mechanism 1 and conveys it to the filter barrel 201 through the dust suction pipe 203 for dust collection. The scraped formed paper 6 is conveyed upward and output upward from the U-shaped groove of the upper cover plate 10105 of the cover assembly 101, and enters the gluing device through the paper guide roller 3, the paper guide plate 4 and the paper guide acceleration wheel 5.
