Description

Technical Field

[0001] The invention belongs to the technical field of feed production and processing batching scales, in particular to a high-precision quantitative control method and device for a feed batching scale. Background Art

[0002] Feed refers to substances that can provide animals with the nutrients they need, promote their growth, development and reproduction, and maintain their health and normal production performance. When processing feed, a variety of raw materials are needed. Feed batching scales can automatically complete the batching of raw materials and achieve high-precision quantification, ensuring a fast and accurate batching process.

[0003] The patent with announcement number CN221706711U discloses a high-precision feed ingredient scale that is easy to adjust, including a ingredient tank, a weighing ring is fixedly provided on the outside of the ingredient tank, a support ring is provided at the bottom of the weighing ring, the support ring and the weighing ring are fixedly connected by a weighing sensor, a plurality of support rods are fixedly provided at equal intervals on the bottom circumference of the support ring, a plurality of fixing rods are fixed on the support rods, the fixing rods pass through the weighing ring and are fixedly connected to the mounting plate, and a discharge pipe is fixedly provided at the bottom of the ingredient tank. This patent stores the ingredients in the weighing hopper in advance, and when the ingredients are needed, uniform discharge can be achieved by controlling the rotating rod to rotate at a uniform speed, and then the weight of the discharged ingredients is judged according to the dual detection data of the weighing sensor and the second weighing sensor. When it is close to the ingredient weight, the rotating rod is controlled to rotate the semicircular baffle slowly, so that the gap between the semicircular baffle and the block becomes smaller and smaller as the weight increases until the balancing is completed, thereby achieving high-precision batching by adjusting the discharge rate and reducing errors.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] First, the required ingredients are stored in a weighing hopper, and the weighing sensor is used to discharge the ingredients into the ingredient tank, so that the ingredients are mixed in the ingredient tank, and then discharged into the container through the discharge pipe. Although quantitative ingredient distribution can be achieved in this way, in some cases, a cylindrical container is used to receive the feed discharged from the discharge pipe. When the diameter of the container opening is smaller than the diameter of the discharge pipe, the feed will fall outside the container, affecting the normal collection of the feed. In order to avoid this situation, the diameter of the discharge pipe is set too small, which will lead to a slow feed discharge speed and affect the collection efficiency. Summary of the Invention

One side of the slider is fixedly connected to motor 2, and the output end of motor 2 is fixedly connected to gear 1.

[0019] The high-precision quantitative control method of the feed batching scale includes the following specific steps:

[0020] S1. Place different kinds of ingredients in different weighing barrels. As the amount of ingredients in the weighing barrel increases, the weight of the weighing barrel will also increase, and the pressure value detected by the pressure sensor will also increase accordingly. When the pressure value stabilizes, this pressure value is recorded as the initial weight.

[0021] S2. Drive the turntable to rotate so that the discharge ports at the bottom of the multiple weighing barrels are aligned with the funnel-shaped structure composed of the batching plate and the elastic cloth in sequence. Then the solenoid valve at the discharge port opens, and the ingredients inside it fall into the funnel-shaped structure. Moreover, according to the pre-set operation, when the pressure value detected by the pressure sensor decreases to a certain value, the solenoid valve closes and stops discharging the materials. In this way, high-precision quantitative batching of feed can be achieved;

[0022] S3. When the feed falls into the funnel-shaped structure formed by the mixing plates and the elastic cloth, the upper surface of the baffle plate fits with the lower end of the mixing plates. Therefore, the feed is blocked by the baffle plate and accumulated inside the funnel-shaped structure. A cylindrical container for collecting the feed is placed at the bottom of the mixing plates. Based on the diameter of the cylindrical container opening, multiple mixing plates are driven to move radially at the same time until the bottom edge of the mixing plates is aligned with the edge of the cylindrical container opening. At the same time, the elastic cloth is also deformed by the movement of the mixing plates until the bottom of the funnel-shaped structure formed by the mixing plates and the elastic cloth matches the size of the cylindrical container opening.

[0023] S4. The baffle is driven to move horizontally away from the bottom of the batching plate, and the mixed feed will fall into the cylindrical container. Since the bottom opening of the funnel-shaped structure matches the opening specifications of the cylindrical container, the feed can fall into the cylindrical container accurately.

[0024] S5. When the feed adheres to the inner surface of the batching plate, the scraper bar 1 is driven to move along the surface of the batching plate so that the scraper bar 1 forms a scraping contact with the surface of the batching plate to scrape off the feed adhered to the surface of the batching plate;

[0025] S6. When there is feed attached to the inner surface of the elastic cloth, the slider is driven to slide on the outer ring of the fixed ring, and the scraper bar 2 and the scraper bar 3 move along the surface of the elastic cloth and scrape the surface of the elastic cloth to make the feed attached to the surface of the elastic cloth fall off.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The high-precision quantitative control method and device of the feed batching scale described in the present invention utilize an adjustable batching mechanism to achieve high-precision quantitative batching of feed. Moreover, after the feed falls into the funnel-shaped structure composed of the batching plates and the elastic cloth, the multiple batching plates can be simultaneously moved radially according to the diameter of the cylindrical container opening until the bottom edges of the batching plates are aligned with the edges of the cylindrical container opening. At the same time, the elastic cloth will also be deformed due to the movement of the batching plates until the bottom of the funnel-shaped structure composed of the batching plates and the elastic cloth matches the size of the cylindrical container opening. The batched feed can be accurately dropped into the cylindrical container, avoiding the situation where the feed falls outside the container due to the cylindrical container opening diameter being smaller than the feed discharge pipe diameter, thereby affecting the normal collection of the feed. In addition, the size of the bottom opening of the funnel-shaped structure depends on the size of the cylindrical container opening, thereby ensuring the discharge speed of the feed to the greatest extent and facilitating the improvement of the feed collection efficiency.

[0028] 2. The high-precision quantitative control method and device for the feed batching scale described in the present invention utilizes self-cleaning components 1 and 2 to scrape off feed adhering to the batching plate and the surface of the elastic cloth, thereby preventing feed from adhering to the batching plate and the inner surface of the elastic cloth during feed discharge, thereby affecting feed collection, and preventing feed residue from affecting subsequent batching accuracy.

[0040] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Please refer to Figures 1-9 The present invention provides a technical solution: a high-precision quantitative control device for a feed ingredient scale, comprising a base 2, one side of the upper end surface of the base 2 is fixedly connected to a frame 1, one side of the upper end of the frame 1 is rotatably provided with a rotating shaft 23, the lower end of the rotating shaft 23 is fixedly connected to a turntable 6, a plurality of weighing barrels 7 are slidably connected to the turntable 6, one side of the upper end of the weighing barrel 7 is fixedly connected to a sliding rod 27, a discharge port 29 is provided at the lower end of the weighing barrel 7, a solenoid valve is provided at the discharge port 29, a sleeve 28 is slidably connected to the sliding rod 27, the lower end of the sleeve 28 is fixedly connected to the turntable 6, a pressure sensor 30 is fixedly connected to the bottom of the inner cavity of the sleeve 28, and an adjustable mixing mechanism is also provided on the frame 1;

[0042] The adjustable dispensing mechanism includes a fixed ring 8 fixedly connected to one side of the frame 1, and a plurality of adjusting rods 9 are radially distributed and slidably connected around the fixed ring 8. One end of the adjusting rod 9 is fixedly connected to a dispensing plate 12, and an elastic cloth 15 is fixedly connected between two adjacent dispensing plates 12. The dispensing plates 12 and the elastic cloth 15 cooperate with each other to form a funnel-shaped structure.

[0043] In this embodiment, Figure 1-Figure 3 As shown, a motor 5 is fixedly connected to one side of the upper end surface of the frame 1, and the output end of the motor 5 is fixedly connected to the upper end of the rotating shaft 23.

[0044] One end of the adjusting rod 9 is rotatably provided with a connecting rod 10, and one end of the connecting rod 10 is rotatably provided with an adjusting ring 11. One side of the fixing ring 8 is fixedly connected to an electric push rod 16, and the piston end of the electric push rod 16 is fixedly connected to one side of the adjusting ring 11.

[0045] One side of the lower end of the frame 1 is fixedly connected to a cylinder 3, and the piston end of the cylinder 3 is fixedly connected to a baffle 4.

[0046] Specifically, in the prior art, the required ingredients are first stored in a weighing hopper, and the ingredients are discharged into the ingredient tank through a weighing sensor, so that the ingredients are mixed in the ingredient tank and then discharged into the container through a discharge pipe. Although quantitative ingredient distribution can be achieved through this method, in some cases, a cylindrical container is used to receive the feed discharged from the discharge pipe. When the diameter of the container opening is smaller than the diameter of the discharge pipe, the feed will fall outside the container, affecting the normal reception of the feed. In order to avoid this situation, the diameter of the discharge pipe is set too small, which will slow down the feed discharge speed and affect the collection efficiency.

[0047] Therefore, in order to solve the above problem, in this embodiment, different kinds of ingredients are placed in different weighing barrels 7 during use. As the amount of ingredients in the weighing barrel 7 increases, the weight of the weighing barrel 7 also increases, and the pressure value detected by the pressure sensor 30 also increases accordingly. When the pressure value stabilizes, this pressure value is recorded as the initial weight.

[0048] Then the motor 15 drives the rotating shaft 23 and the turntable 6 to rotate, so that the discharge ports 29 at the bottom of the multiple weighing barrels 7 are aligned with the funnel-shaped structure composed of the batching plate 12 and the elastic cloth 15 in sequence. Then the solenoid valve at the discharge port 29 opens, and the ingredients inside it fall into the funnel-shaped structure. Moreover, according to the pre-set operation, when the pressure value detected by the pressure sensor 30 decreases to a certain value, the solenoid valve closes and stops discharging the materials. In this way, high-precision quantitative batching of feed can be achieved.

[0049] When the feed falls into the funnel-shaped structure composed of the batching plate 12 and the elastic cloth 15, the upper end surface of the baffle 4 fits with the lower end of the batching plate 12, so the feed will be blocked by the baffle 4 and accumulated inside the funnel-shaped structure. Then, a cylindrical container for collecting the feed is placed at the bottom of the batching plate 12, and according to the diameter of the opening of the cylindrical container, the electric push rod 16 is used to drive the adjustment ring 11 to rise and fall. When the adjustment ring 11 rises and falls, the connecting rod 10 rotates and drives the adjustment rod 9 to slide on the fixed ring 8, so that the multiple batching plates 12 move radially at the same time until the bottom edge of the batching plate 12 is aligned with the edge of the cylindrical container opening. At the same time, the elastic cloth 15 will also be deformed due to the movement of the batching plate 12 until The bottom of the funnel-shaped structure composed of the batching plate 12 and the elastic cloth 15 matches the size of the opening of the cylindrical container. At this time, the baffle 4 can be driven by the cylinder 13 to move horizontally, so that the baffle 4 is away from the bottom of the batching plate 12, and the proportioned feed will fall into the cylindrical container. Since the bottom opening of the funnel-shaped structure matches the specifications of the opening of the cylindrical container, the feed can fall into the cylindrical container accurately, thereby avoiding the situation where the feed falls outside the container due to the diameter of the cylindrical container opening being smaller than the diameter of the feed discharge pipe, affecting the normal collection of the feed. In addition, the size of the bottom opening of the funnel-shaped structure depends on the size of the cylindrical container opening, which ensures the discharge speed of the feed to the greatest extent and is conducive to improving the collection efficiency of the feed.

[0050] In this embodiment, Figure 3-Figure 7 As shown, the batching plate 12 is also provided with a self-cleaning component 1;

[0051] The self-cleaning component 1 includes a scraper 13 slidably connected to the upper end surface of the ingredient plate 12 , and the scraper 13 is in contact with the surface of one side of the ingredient plate 12 .

[0052] A second gear 32 is rotatably provided on one side of the upper end of the scraper bar 13 , and a plurality of tooth blocks are provided on one side of the upper end of the dispensing plate 12 . The second gear 32 meshes with the tooth blocks on the dispensing plate 12 .

[0053] One side of the upper end of the scraper strip 13 is fixedly connected to the motor 31 , and the output end of the motor 31 is fixedly connected to the gear 2 32 .

[0054] The fixing ring 8 is also provided with multiple sets of self-cleaning components 2 for clearing the feed on the surface of the elastic cloth 15;

[0055] Self-cleaning component 2 includes a slider 18 slidably connected to the outer ring surface of the fixed ring 8, and a lower end of the slider 18 is fixedly connected to a cylinder 25, and a piston end of the cylinder 25 is fixedly connected to an L-shaped block 14, and an upper end of the L-shaped block 14 is fixedly connected to two spring dampers 21, and a piston end of the spring damper 21 is fixedly connected to a connecting block 22, and one side of the connecting block 22 is slidably connected to a limit rod 20, and both ends of the limit rod 20 are fixedly connected to the L-shaped block 14, and one end of the lower side of the two connecting blocks 22 is fixedly connected to a scraper 2 17 and a scraper 3 26 respectively.

[0056] Multiple groups of gear blocks are intermittently provided on the outer ring of the fixed ring 8. A gear 19 is rotatably provided on one side of the upper end surface of the slider 18. The gear 19 is engaged with the gear blocks on the outer ring of the fixed ring 8. A motor 24 is fixedly connected to one side of the slider 18, and the output end of the motor 24 is fixedly connected to the gear 19.

[0057] Specifically, in the above embodiment, the prepared feed is concentrated in the funnel-shaped structure formed by the batching plate 12 and the elastic cloth 15. When the feed is discharged, it is easy for the feed to adhere to the inner surface of the batching plate 12 and the elastic cloth 15, which not only affects the collection of the feed, but also affects the subsequent batching accuracy due to the residual feed.

[0058] Therefore, in order to solve the above problem, when the present embodiment is in use, when the feed adheres to the inner surface of the batching plate 12, the motor 3 31 drives the gear 2 32 to rotate, so that the scraper 13 is in contact with the upper end surface of the batching plate 12, and the scraper 13 moves along the surface of the batching plate 12, so that the scraper 13 and the surface of the batching plate 12 form a scraping action, thereby scraping off the feed adhered to the surface of the batching plate 12;

[0059] When feed is attached to the inner surface of the elastic cloth 15, since the elastic cloth 15 is made of flexible material, the scraper bar 2 17 and the scraper bar 3 26 press the elastic cloth 15 under the action of the spring damper 21. The scraper bar 2 17 and the scraper bar 3 26 are in close contact with the elastic cloth 15. Moreover, when the position of the batching plate 12 is adjusted, the cylinder 2 25 also drives the L-shaped block 14 to move, so that the position of the L-shaped block 14 and the batching plate 12 always correspond to each other. The motor 2 24 drives the gear 19 to rotate, so that the slide When the block 18 slides on the outer ring of the fixed ring 8, the scraper bar 2 17 and the scraper bar 3 26 move along the surface of the elastic cloth 15 and scrape the surface of the elastic cloth 15, so that the feed adhering to the surface of the elastic cloth 15 falls off. At this point, the feed adhering to the surface of the ingredient plate 12 and the elastic cloth 15 is scraped off, avoiding the situation where the feed is adhered to the ingredient plate 12 and the inner surface of the elastic cloth 15 when the feed is discharged, thereby affecting the collection of the feed, and affecting the subsequent ratio accuracy due to the residual feed.

[0060] The high-precision quantitative control method of the feed batching scale includes the following specific steps:

[0061] S1. Place different kinds of ingredients in different weighing barrels 7. As the amount of ingredients in the weighing barrel 7 increases, the weight of the weighing barrel 7 also increases, and the pressure value detected by the pressure sensor 30 also increases accordingly. When the pressure value stabilizes, this pressure value is recorded as the initial weight.

[0062] S2, driving the turntable 6 to rotate, so that the discharge ports 29 at the bottom of the multiple weighing barrels 7 are aligned with the funnel-shaped structure composed of the batching plate 12 and the elastic cloth 15 in sequence, and then the solenoid valve at the discharge port 29 is opened, and the ingredients inside it will fall into the funnel-shaped structure. Moreover, according to the pre-set operation, when the pressure value detected by the pressure sensor 30 decreases to a certain value, the solenoid valve is closed and the feeding is stopped. In this way, high-precision quantitative batching of feed can be achieved;

[0063] S3. When the feed falls into the funnel-shaped structure formed by the batching plates 12 and the elastic cloth 15, the upper end surface of the baffle 4 fits against the lower end of the batching plates 12. Therefore, the feed is blocked by the baffle 4 and accumulated inside the funnel-shaped structure. A cylindrical container for collecting the feed is placed at the bottom of the batching plates 12. In addition, according to the diameter of the cylindrical container opening, multiple batching plates 12 are driven to move radially at the same time until the bottom edge of the batching plates 12 is aligned with the edge of the cylindrical container opening. At the same time, the elastic cloth 15 is also deformed by the movement of the batching plates 12 until the bottom of the funnel-shaped structure formed by the batching plates 12 and the elastic cloth 15 matches the size of the cylindrical container opening.

[0064] S4, driving the baffle 4 to move horizontally, so that the baffle 4 is away from the bottom of the ingredient plate 12, and the proportioned feed will fall into the cylindrical container. Since the bottom opening of the funnel-shaped structure matches the opening specifications of the cylindrical container, the feed can fall into the cylindrical container accurately;

[0065] S5. When the feed adheres to the inner surface of the batching plate 12, the scraper bar 13 is driven to move along the surface of the batching plate 12 so that the scraper bar 13 and the surface of the batching plate 12 form a scraping action to scrape off the feed adhered to the surface of the batching plate 12;

[0066] S6. When feed adheres to the inner surface of the elastic cloth 15, the slider 18 is driven to slide on the outer ring of the fixed ring 8, and the scraper bar 2 17 and the scraper bar 3 26 move along the surface of the elastic cloth 15 and scrape the surface of the elastic cloth 15 to make the feed adhered to the surface of the elastic cloth 15 fall off.

[0067] Working principle: different kinds of ingredients are placed in different weighing barrels 7. As the amount of ingredients inside the weighing barrel 7 increases, the weight of the weighing barrel 7 also increases, and the pressure value detected by the pressure sensor 30 also increases accordingly. When the pressure value stabilizes, this pressure value is recorded as the initial weight; then the motor 15 drives the rotating shaft 23 and the turntable 6 to rotate, so that the discharge ports 29 at the bottom of the multiple weighing barrels 7 are aligned with the funnel-shaped structure composed of the ingredient plate 12 and the elastic cloth 15 in turn, and then the solenoid valve at the discharge port 29 is opened, and the ingredients inside it will fall into the funnel-shaped structure, and, according to the pre-set operation, when the pressure sensor 30 When the detected pressure value decreases to a certain value, the solenoid valve closes and stops feeding, and high-precision quantitative feeding of feed can be achieved in this way; when the feed falls into the funnel-shaped structure composed of the feeding plate 12 and the elastic cloth 15, the upper end surface of the baffle 4 fits with the lower end of the feeding plate 12, so the feed will be blocked by the baffle 4 and accumulated inside the funnel-shaped structure. Then, a cylindrical container for collecting the feed is placed at the bottom of the feeding plate 12, and according to the diameter of the opening of the cylindrical container, the electric push rod 16 is used to drive the adjustment ring 11 to rise and fall. When the adjustment ring 11 rises and falls, the connecting rod 10 will rotate and drive the adjustment rod 9 slides on the fixing ring 8, so that the multiple batching plates 12 move radially at the same time until the bottom edge of the batching plate 12 is aligned with the edge of the opening of the cylindrical container. At the same time, the elastic cloth 15 will also be deformed due to the movement of the batching plate 12, until the bottom of the funnel-shaped structure composed of the batching plate 12 and the elastic cloth 15 matches the size of the opening of the cylindrical container. At this time, the baffle 4 can be driven by the cylinder 13 to move horizontally, so that the baffle 4 is away from the bottom of the batching plate 12, and the proportioned feed will fall into the cylindrical container. Since the bottom opening of the funnel-shaped structure matches the specifications of the opening of the cylindrical container, the feed can fall into the cylindrical container accurately, thereby avoiding This avoids the situation where the feed falls outside the container due to the diameter of the cylindrical container opening being smaller than the diameter of the feed discharge pipe, thereby affecting the normal collection of the feed. In addition, the size of the bottom opening of the funnel-shaped structure depends on the size of the cylindrical container opening, thereby ensuring the discharge speed of the feed to the greatest extent and facilitating the improvement of the feed collection efficiency. When the feed adheres to the inner surface of the batching plate 12, the motor 31 drives the gear 2 32 to rotate, so that the scraper 13 fits the upper end surface of the batching plate 12, and the scraper 13 moves along the surface of the batching plate 12, so that the scraper 13 and the surface of the batching plate 12 form a scraping action, thereby scraping off the feed adhered to the surface of the batching plate 12.When feed is attached to the inner surface of the elastic cloth 15, since the elastic cloth 15 is made of flexible material, the scraper bar 2 17 and the scraper bar 3 26 press the elastic cloth 15 under the action of the spring damper 21. The scraper bar 2 17 and the scraper bar 3 26 are in close contact with the elastic cloth 15. Moreover, when the position of the batching plate 12 is adjusted, the cylinder 2 25 also drives the L-shaped block 14 to move, so that the position of the L-shaped block 14 and the batching plate 12 always correspond to each other. The motor 2 24 drives the gear 19 to rotate, so that the slide As block 18 slides on the outer ring of fixed ring 8, scraper bar 2 17 and scraper bar 3 26 move along the surface of elastic cloth 15 and scrape the surface of elastic cloth 15, causing feed adhering to the surface of elastic cloth 15 to fall off. This effectively scrapes off feed adhering to the surface of mixing plate 12 and elastic cloth 15, preventing feed from adhering to the mixing plate 12 and the inner surface of elastic cloth 15 during discharge, thereby affecting feed collection and preventing feed residue from affecting subsequent mixing accuracy.

[0068] The basic principles, main features, and advantages of the present invention are shown and described above.

10. A high-precision quantitative control method for a feed batching scale, characterized in that: The control device according to any one of claims 1 to 9 is used for control, comprising the following specific steps: S1. Different kinds of ingredients are placed in different weighing barrels (7). As the amount of ingredients in the weighing barrel (7) increases, the weight of the weighing barrel (7) also increases, and the pressure value detected by the pressure sensor (30) also increases accordingly. When the pressure value stabilizes, this pressure value is recorded as the initial weight; S2, driving the turntable (6) to rotate, so that the discharge ports (29) at the bottom of the plurality of weighing barrels (7) are aligned with the funnel-shaped structure composed of the batching plate (12) and the elastic cloth (15) in sequence, and then the solenoid valve at the discharge port (29) is opened, and the ingredients inside it fall into the funnel-shaped structure, and, according to the pre-set operation, when the pressure value detected by the pressure sensor (30) decreases to a certain value, the solenoid valve is closed and the feeding is stopped, so that high-precision quantitative batching of feed can be achieved in this way; S3. When the feed falls into the funnel-shaped structure composed of the batching plate (12) and the elastic cloth (15), the upper end surface of the baffle (4) is in contact with the lower end of the batching plate (12). Therefore, the feed is blocked by the baffle (4) and accumulated inside the funnel-shaped structure. A cylindrical container for collecting the feed is placed at the bottom of the batching plate (12). Furthermore, according to the diameter of the opening of the cylindrical container, a plurality of batching plates (12) are driven to move radially at the same time until the bottom edge of the batching plate (12) is aligned with the opening edge of the cylindrical container. At the same time, the elastic cloth (15) is also deformed due to the movement of the batching plate (12) until the bottom of the funnel-shaped structure composed of the batching plate (12) and the elastic cloth (15) matches the size of the opening of the cylindrical container. S4, driving the baffle (4) to move horizontally, so that the baffle (4) is away from the bottom of the batching plate (12), and the proportioned feed will fall into the cylindrical container. Since the bottom opening of the funnel-shaped structure matches the opening specifications of the cylindrical container, the feed can fall into the cylindrical container accurately; S5. When the feed adheres to the inner surface of the batching plate (12), the scraper bar 1 (13) is driven to move along the surface of the batching plate (12), so that the scraper bar 1 (13) and the surface of the batching plate (12) form a scraping action to scrape off the feed adhered to the surface of the batching plate (12); S6. When feed adheres to the inner surface of the elastic cloth (15), the slider (18) is driven to slide on the outer ring of the fixed ring (8), and the scraper bar 2 (17) and the scraper bar 3 (26) move along the surface of the elastic cloth (15) and scrape the surface of the elastic cloth (15), so that the feed adhered to the surface of the elastic cloth (15) falls off.
