Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field especially a scraper distance adjusting mechanism of laundry tablet thickness drum dryer. BACKGROUND

[0002] The laundry tablet making machine is a device for producing laundry tablets. First, the laundry raw materials are mixed to form a slurry, which is poured into a trough. The slurry is evenly coated on the outer surface of the drying drum by the rotating feeding roller. The drying drum is heated by the heating device to make the slurry preliminarily dry and form. The formed laundry tablets are removed by the scraper to remove bubbles and excess material, making the surface of the formed material smooth and clean. Finally, the formed laundry tablets are wound by the winding mechanism. During production, the distance between the drying drum and the scraper needs to be adjusted according to the thickness of the laundry tablets to be produced. The traditional method is to manually adjust the scraper and determine whether the adjusted size is appropriate according to the formed laundry tablets. However, this method requires high technical skills of the operator, and the appropriate size can only be adjusted after producing a part of the laundry tablets at the front end of the production line. The operation time is long, and the debugging effect is unstable.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN218928692U, patent name: laundry tablet making machine) is as follows: the abutting member includes an abutting rod, the center of the crossbar is provided with an upper sliding hole penetrating the crossbar in the thickness direction, one end of the sliding block close to the crossbar is provided with a cylindrical positioning hole, the abutting rod passes through the upper sliding hole and the positioning hole in sequence and is inserted with the sliding block, there is a certain spacing between the abutting rod and the sliding block, the abutting rod passes through the upper sliding hole and is threadedly connected with the crossbar, the abutting member is used for fixing the sliding block to reduce the occurrence of upward displacement of the sliding block. The abutting member includes a second spring, the second spring is located between the crossbar and the sliding block, the two ends of the second spring are respectively abutted with the crossbar and the sliding block, the abutting rod passes through the second spring, when the sliding block is displaced upward, the second spring can provide elastic protection to reduce the occurrence of damage to the equipment. The tablet making assembly further includes an embossing member, the embossing member includes an embossing roller, a rotating bearing and an embossing template, the center of the sliding block is provided with a roller shaft hole penetrating the sliding block in the thickness direction, the rotating bearing is penetrated in the roller shaft hole and is clamped with the sliding block, the two ends of the embossing roller are respectively penetrated through the inner rings of the two rotating bearings and are rotationally connected with the sliding block.

[0004] From the above embodiment and the corresponding drawing display can be known that, the laundry tablet press is adjusted by rotating the adjusting rod manually to adjust the position of the sliding block, so as to adjust the distance between the embossing piece and the lower roller, and finally adjust the thickness of the laundry tablet. However, rotating the adjusting rod cannot intuitively see the distance between the embossing piece and the lower roller, so when the equipment is working, it must be tested first, and only after the size of the laundry tablet is stable can the production be formally carried out, so that the equipment has higher requirements for the operator when adjusting the machine, and depends on the experience of the operator, and a certain amount of laundry tablets will be wasted before the formal production of the product, which will lead to waste of materials and time.

The servo motor 301 drives the screw rod 302 to rotate, so that the connecting seat 307 drives the scraper 2 to move, thereby adjusting the distance between the scraper 2 and the drying roller 1. Therefore, when the distance between the scraper 2 and the drying roller 1 is adjusted and set, only the corresponding numerical value or code needs to be input on the equipment, and then the servo motor 301 can be used for automatic adjustment. Compared with the traditional manual adjustment, this method is more fast and accurate, and the adjusted numerical value can be displayed through the display, which is more intuitive.

[0026] The feeding roller 5 is connected with the second adjusting component 4, and the second adjusting component 4 has the same structure as the first adjusting component 3. The second adjusting component 4 is used for adjusting the gap between the feeding roller 5 and the drying roller 1, and the thickness of the feeding is determined according to the size of the gap. Then, the excess material and the steam bubbles are scraped off by the scraper 2 to achieve the final required thickness.

[0027] The screw rod 302 is provided with a sliding rod 303 on both sides, the sliding rod 303 is slidingly connected with a sliding block 305, the sliding block 305 is connected with the moving plate 306, and a linear bearing is arranged in the sliding block 305, so that the linkage of the sliding block 305 and the sliding rod 303 is smoother. The sliding rod 303 makes the moving plate 306 not rotate during movement, so that the connecting seat 307 can only move in the length direction of the screw rod 303.
