Description

Technical Field

[0001] This invention relates to the field of flower sprinkler technology, specifically to a flower sprinkler and a flower sprinkling process. Background Technology

[0002] Floor coverings / floor fabrics are mainly used for the decoration of floors in industries, schools, hospitals, etc. In order to increase the decorative effect and wear resistance, manufacturers usually sprinkle soft or hard granular materials of different colors and shapes on the surface of the floor coverings / floor fabrics during the preparation process.

[0003] The following requirements apply to the application of granules on the surface of the flooring / floor cover (the corresponding process is the scattering process): 1. The distribution of granules on the surface of the flooring / floor cover should be uniform; 2. When the granules include larger and smaller granules, the proportion of larger and smaller granules in the granules at any location on the surface of the flooring / floor cover should be basically the same.

[0004] Chinese utility model patent CN202323591194.0 discloses a pellet spreader. This utility model uses a reducer to drive a spreading roller to rotate. The spreading roller, with its concave surface (for accommodating particles), carries out colored rubber particles from a hopper, achieving a uniform and irregular spreading of colored rubber particles onto the surface of a rubber sheet. However, when using this pellet spreader to spread hard particles, the roller surface comes into high-frequency contact with the hard particles, easily reducing the roller's lifespan due to wear and tear. Furthermore, this pellet spreader struggles to evenly spread particles across the width of the rubber sheet. Summary of the Invention

[0005] One of the objectives of this invention is to provide a flower-spreading machine that, when used to spread hard granular materials, does not easily shorten the service life of the equipment.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention. Example

[0019] The embodiment of the flower sprinkler includes a sprinkling component 3 and a material guide 4. The sprinkling component 3 includes a material trough 303 and a plurality of material scoops 301 that are spaced apart above the material trough 303 along a first direction x and are connected to a rotation drive 304 via a rotating shaft 302. The material guide 4 is located below the sprinkling component 3 and includes an impact guide plate 4 for receiving the granular material sprinkled by the material scoops 301 and a narrow discharge port 402 located below the impact guide plate 4 and having a first orthographic projection on a horizontal plane. The impact guide plate 401 is parallel to the first direction x, and the length direction of the first orthographic projection is parallel to the first direction x.

[0020] Specifically, such as Figures 1-5As shown, the flower sprinkler in this embodiment has a frame 5, which is positioned above the floor mat conveyor belt 1. The conveying direction of the floor mat conveyor belt 1 is parallel to the length direction of the floor mat 2. The material spreading component 3 and the material guiding component 4 of the flower sprinkler in this embodiment are both mounted on the frame 5. The material spreading component 3 includes a material trough 303, a rotating shaft 302, a material scoop 301, and a rotation drive component 304. The material trough 303 is used to hold granular material. Multiple material scoops 301 are spaced apart along a first direction x and fixedly connected to the rotating shaft 302. The rotating shaft 302 and the rotation drive component 304 are connected in a driving connection. The rotating shaft 302 extends along the first direction x. The material scoops 301 are used to scoop up the granular material from the material trough 303. The scooping part of the scoop 301 is preferably located at the end of the scoop 301 away from the rotating shaft 302. The scooping part of the scoop 301 has a scooping concave surface (the end face of the rod end of the rod-shaped scoop 301 is concave, and the plane where the scoop opening of the scoop 301 is located is preferably a radial section of the rotating shaft 302, or a radial section parallel to the rotating shaft 302). The guide component 4 is located below the spreading component 3. The guide component 4 includes an impact guide plate 401 and a narrow discharge port 402. The impact guide plate 401 is used to receive the granular material spread by the scoop 301. After the granular material falls onto the surface of the impact guide plate 401, it will slightly bounce, slide and scatter, and finally fall off. The scattered granular material falls through the narrow discharge port 402 and is embedded in the surface of the floor mat. Ultimately, the granules are dispersed in the width direction of the floor 2, filling the gaps between adjacent scoops, and are evenly distributed in the width direction of the floor 2; the granules are dispersed in the length direction of the floor 2 and / or dispersed in the height direction of impacting the guide plate, so that the granules fall onto the floor 2 one after another, and the spilled material from the previous scoop and the next scoop are connected in the length direction of the floor 2, thereby achieving a uniform distribution of the granules in the length direction of the floor 2.

[0021] The elongated discharge port 402 is located below the impact guide plate 401. After falling along the impact guide plate 401, the granular material falls from the elongated discharge port 402 onto the surface of the floor mat 2. The impact guide plate 401 is parallel to the first direction x, and the length direction of the orthographic projection of the elongated discharge port 402 on the horizontal plane is parallel to the first direction x. The first direction x is perpendicular to the length direction of the floor mat 2 (below the sprinkler).

[0022] The working process of the flower-sprinkling machine of the present invention includes: S1: Floor rubber conveyor belt 1 conveys floor rubber 2; S2: The rotating drive 304 drives the rotating shaft 302 to rotate, which in turn drives the scoop 301 to rotate. The scoop 301 scoops up the granules in the trough 303 and then sprinkles the granules onto the impact guide plate 401 below the trough 303. S3: After the granular material collides with the impact guide plate 401, it first scatters and then falls along the impact guide plate 401; S4: The granular material falls from the narrow discharge port 402 and lands on the surface of the floor mat 2.

[0023] The material scoop 301, in conjunction with the guide component 4, is used for material spreading. This design ensures that the lifespan of the spreading mechanism, especially the spreading roller, is not shortened due to friction with the granules. The rotating scoop 301 prevents clogging and clumping, thus promoting uniform granule thickness across the surface of the floor mat 2. After colliding with the impact guide plate 401, the granules scatter, ensuring even distribution of the granules along both the length and width of the floor mat 2.

[0024] When the granules are hard and dense, the main factors affecting the degree of scattering after the granules fall include: 1. Granule shape; 2. Granule density; 3. Elastic modulus of granules; 4. Impact angle between granules and impact guide plate 401; 5. The height difference between the falling position of granules and guide plate 401; 6. The angle of collision between granules; 7. Kinetic energy of collision between granules.

[0025] When the granular material is a soft, low-density, flaky particle, the main factors affecting the degree of dispersion after the particle falls include: 1. The aspect ratio of the flaky particle; 2. The particle size distribution of the flaky particle; 3. The density of the flaky particle; 4. The elastic modulus of the flaky particle; 5. The impact angle between the flaky particle and the impact guide plate 401; 6. The height difference between the falling position of the flaky particle and the guide plate 401; 7. The angle of collision between the flaky particles; 8. The kinetic energy of the collision between the flaky particles. In addition, particles with a larger aspect ratio and the degree of dispersion before impact with the guide plate 401 are significantly affected by air turbulence.

[0026] In another preferred embodiment, the plurality of scoops 301 include a plurality of first scoops 3011 and second scoops 3012 that are spaced apart along a first direction x. The scooping portions of the plurality of first scoops 3011 are spaced apart along a second direction, and the scooping portions of the plurality of second scoops 3012 are spaced apart along a third direction. Both the second direction and the third direction are parallel to the first direction x.

[0027] Specifically, such as Figure 6 and Figure 7 As shown, the scoop 301 includes a first scoop 3011 and a second scoop 3012. The first scoop 3011 and the second scoop 3012 are distributed alternately along a first direction x. The first scoop 3011 and the second scoop 3012 have the same structure, the difference being that the scooping parts of the multiple first scoops 3011 are distributed alternately along a second direction, and the scooping parts of the multiple second scoops 3012 are distributed alternately along a third direction. Both the second direction and the third direction are parallel to the first direction x.

[0028] By setting up a first scoop 3011 and a second scoop 3012, the occurrence of dotted or striped spillage gaps that are prone to occur when using a single scoop 301 is effectively reduced.

[0029] In another preferred embodiment, a first impact plate 6 is also included. The material trough 303 has a first side wall 3031 and a second side wall 3032 located above the first side wall 3031. The first side wall 3031 and the first impact plate 5 have a first distance, and the second side wall 3032 and the first impact plate 6 have a second distance. The first distance is smaller than the second distance. The first impact plate 6 is fixedly connected to the material trough 303. The first impact plate 6 has a vertical impact surface, and the guide member 4 is located below the first impact plate 6.

[0030] Specifically, such as Figure 4 and Figure 5 As shown, the flower sprinkler also includes a vertically arranged first impact plate 6. The surface of the first impact plate 6 near the material trough 303 is a vertical impact surface, and the guide member 4 is located below the first impact plate 6. The opening of the material trough 303 faces upward, and the material trough 303 has a first sidewall 3031 near the first impact plate 6 and a second sidewall 3032 away from the first impact plate 6. The height of the first sidewall 3031 is lower than the height of the second sidewall 3032.

[0031] After the first impact plate 6 is set, S2 in the working process of the flower sprinkler of the present invention becomes: The rotating drive 304 drives the rotating shaft 302 to rotate, which in turn drives the scoop 301 to rotate. The scoop 301 scoops up the granules in the trough 303 and then sprinkles the granules onto the first impact plate 6. The granules scatter after colliding with the first impact plate 6, and the scattered granules fall onto the impact guide plate 401 below.

[0032] The granules sprinkled by the scoop 301 onto the first impact plate 6 collide with the first impact plate 6 and scatter (the granules in the scoop 301 are first broken up and then scattered after colliding with the first impact plate 6). On the one hand, this helps to reduce the agglomeration of granules, which could lead to excessively thick or thin granules in some areas of the floor mat 2. On the other hand, it helps to make the granules more evenly distributed in the width direction of the floor mat 2.

[0033] The preferred operating path of the scoop 301 is as follows: first, it scoops up the granular material from the trough 303; then, it rotates from the first sidewall 3031 to the second sidewall 3032; finally, it turns towards the first impact plate 6 and scatters the granular material onto the first impact plate 6. With this preferred path, the granular material impacting the first impact plate 6 is subjected not only to the centrifugal force applied by the rotation but also to its own gravity, which helps to increase the speed at which the granular material impacts the first impact plate 6, thereby enhancing the dispersing effect of the first impact plate 6 on the granular material.

[0034] In another preferred embodiment, a second impact plate 7 is fixedly connected below the material spreading assembly 3 and is disposed opposite to the first impact plate 6, and the material guide 4 is located below the second impact plate 7.

[0035] Specifically, such as Figure 4 and Figure 10As shown, the flower sprinkler also includes a vertically arranged second impact plate 7, which is located between the material spreading assembly 3 and the material guide 4 in the height direction. The surface of the second impact plate 7 closest to the first impact plate 6 is the impact surface.

[0036] After the scoop 301 sprinkles the granules onto the first impact plate 6, they fall towards the lower impact guide plate 401. During this process, each granule impacts the first impact plate 6 (and other granules, and even the impact guide plate 401) a different number of times, resulting in a time difference between when different granules are scooped up and when they fall from the narrow discharge port 402. With the second impact plate 7 installed, the granules will impact the second impact plate 7 (also increasing the probability of impact with other granules), thus increasing the aforementioned time difference and facilitating a more uniform distribution of the granules along the length of the floor mat 2.

[0037] In another preferred embodiment, the lower end 701 of the second impact plate 7 has a third distance from the first impact plate 7, and the upper end 702 of the second impact plate 7 has a fourth distance from the first impact plate 7, wherein the third distance is smaller than the fourth distance.

[0038] Specifically, such as Figure 10 As shown, the distance between the lower end 701 of the second impact plate 7 and the first impact plate 6 is smaller than the distance between the upper end 702 of the second impact plate 7 and the first impact plate 6. The second impact plate 7 is inclined, and the particles collide left and right during the falling process. On the one hand, it is beneficial to improve the dispersing effect, and on the other hand, it is beneficial to increase the falling time difference of different particles (which in turn is beneficial to make the particles more evenly distributed in the length direction of the floor adhesive 2).

[0039] In another preferred embodiment, the 3-powdering assembly includes an upper powdering assembly a and a lower powdering assembly b. The upper powdering assembly a has a fifth distance from the first impact plate 6, and the lower powdering assembly b has a sixth distance from the first impact plate 6. The fifth distance is smaller than the sixth distance.

[0040] Specifically, such as Figure 4 As shown, the upper material spreading component a is located above the lower material spreading component b, and the distance between the upper material spreading component a and the first impact plate 6 is smaller than the distance between the lower material spreading component b and the first impact plate 6.

[0041] The upper and lower spreading components can respectively hold and spread two different colors / sizes of granules to achieve a double-layer composite spreading process. The upper spreading component a is closer to the first impact plate 6, resulting in a strong impact force and a strong dispersing effect, suitable for fine powder granules that are prone to clumping; the lower spreading component b is farther from the first impact plate 6, resulting in a gentler impact force, suitable for large, fragile granules. When spreading hard, high-density granules of different densities at the same time, it is preferable to place the granules of different densities into different troughs, which helps to increase the probability of collision between granules of different densities during the fall, thereby improving the uniformity of the distribution of granules in the width direction of the floor lining 2.

[0042] In another preferred embodiment, the material spreading component 3 includes a first material spreading component c and a second material spreading component d arranged horizontally, with the first material spreading component c and the second material spreading component d symmetrically arranged on both sides of the thickness direction of the first impact plate 6.

[0043] Specifically, such as Figure 4 As shown, the first spreading component c and the second spreading component d are symmetrically arranged on both sides of the thickness direction of the first impact plate 6. After the first spreading component c spreads the granules onto the first impact plate 6, the first impact plate 6 will vibrate slightly (this vibration will last for a period of time). At this time, the granules spread by the second spreading component d onto the first impact plate 6 will be more easily scattered under the influence of this vibration, which will help the granules to be distributed more evenly in the width direction of the floor mat 2.

[0044] In another preferred embodiment, an electromagnetic vibrator 8 is fixedly disposed on the first impact plate 6, and the electromagnetic vibrator 8 is configured to apply an excitation force in the thickness direction to the first impact plate 6.

[0045] Specifically, such as Figure 8 and Figure 9 As shown, the electromagnetic vibrator 8 is mounted on the frame 5. The electromagnetic vibrator 8 is configured to apply a vibrational force in the thickness direction to the first impact plate 6. On the one hand, the first impact plate 6 vibrates slightly under the action of the electromagnetic vibrator 8, making it difficult for the granules to adhere to the surface of the first impact plate 6 when they collide. On the other hand, the granules sprinkled onto the first impact plate 6 are fully dispersed under the dual action of impact and vibration (the dispersion effect is better than simple collision, which is conducive to a more uniform distribution of granules in the width direction of the floor 2). In addition, the material trough 303 vibrates slightly under the action of the electromagnetic vibrator 8, and the material height in the material trough 303 tends to be uniform, which is conducive to the uniform amount of material scooped by each scoop 301, and thus facilitates the uniform distribution of granules in the width direction of the floor 2. To enhance the vibration amplitude of the first impact plate 6 under the action of the electromagnetic vibrator 8, the first impact plate 6 and the frame 5 are preferably connected by an elastic element (the first impact plate 6 may be fixedly connected to one end of a plurality of compression springs, and the other end of the compression springs may be fixedly connected to the frame 5; the first impact plate 6 may also be inserted into a slot on the frame 5, and a polyurethane elastic plate is filled between the first impact plate 6 and the slot).

[0046] In another preferred embodiment, the impact guide plate 401 includes a first impact guide plate 4011 and a second impact guide plate 4012 disposed opposite to the first impact guide plate 4011. The first impact guide plate 4011 and the second impact guide plate 4012 are fixedly connected. The first impact guide plate 4011 has a first acute angle with the horizontal plane, and the second impact guide plate 4012 has a second acute angle with the horizontal plane. The first acute angle is smaller than the second acute angle, and the bottom edge of the first impact guide plate 4011 is located above the bottom edge of the second impact guide plate 4012.

[0047] Specifically, such as Figure 10 As shown, the first impact guide plate 4011 has a smaller horizontal inclination angle and a higher position, which catches the falling granules first, reducing the occurrence of granules rebounding and flying out. The second impact guide plate 4012 has a larger inclination angle, which facilitates smooth material feeding and prevents material accumulation. In addition, the falling granules first fall onto the first impact guide plate 4011 (and impact it) and then impact the second impact guide plate 4012, which helps to further disperse the granules and thus facilitates the uniform distribution of granules in the width direction of the floor mat 2.

[0048] In another preferred embodiment, the rotating shaft 302 includes a splined shaft 3021 and a rotating sleeve 3022 coaxially arranged. The rotating sleeve 3022 is sleeved on the outside of the splined shaft 3021 and meshes with the splined shaft 3021. The splined shaft 3021 is connected to the rotation drive 304 for transmission. The rotating sleeve 3022 is fixedly connected to the scoop 301. It also includes a cylinder 9 fixedly connected to the frame 5. The piston rod of the cylinder 9 extends along the first direction x and a pusher 10 is fixedly connected to its end. The pusher 10 has two pusher surfaces arranged opposite to each other along the first direction x. The end of the rotating sleeve 3022 has a pusher disc 30221 coaxially arranged. The disc surface of the pusher disc 30221 in the first direction x is located between the two pusher surfaces.

[0049] Specifically, such as Figure 11 , Figure 12 , Figure 13As shown, the splined shaft 3021 has a first tooth on its surface, and the inner ring surface of the rotating bushing 3022 has a second tooth. The first tooth meshes with the second tooth, so when the splined shaft 3021 rotates, it will drive the rotating bushing 3022 to rotate. When the cylinder 9 is working, the pusher 10 reciprocates along the first direction x, which in turn pushes the pusher disc 30221, ultimately realizing the reciprocating motion of the rotating bushing 3022 in the first direction x. On the one hand, this facilitates a more uniform distribution of the granular material in the trough 303 in the first direction x (reducing the frequency of manually leveling the granular material after machine shutdown, thereby improving production efficiency), and on the other hand, it facilitates a more uniform distribution of the granular material in the first direction. The above-mentioned mating structure of the splined shaft 3021 and the rotating bushing 3022 can be further preferably a ball spline transmission device. The ball spline transmission device consists of a splined shaft, a splined bushing, a circulation device, and balls. Generally, the outer surface (outer circle) of a splined shaft has three equally spaced raised tracks, each holding 12 rows of balls. Six tracks are used for load loading, and the other six are used for ball recirculation and unloading. As the splined sleeve moves along the splined shaft, the balls circulate within the raceways and retaining channels, and can automatically center themselves. A certain amount of torque can also be transmitted between the splined sleeve and the splined shaft via the balls. When the load on the splined sleeve is relatively small, three of the six load-bearing ball rows can automatically center themselves and transmit torque, while the other three do not bear any load. During reverse rotation, the other three balls bear the load and automatically center themselves. By selecting the appropriate ball diameter, an interference fit (preload) is created within the ball spline pair to improve contact stiffness, motion accuracy, and impact resistance. The spline sleeve has a keyway for connecting other transmission components; the cage prevents the balls from rubbing against each other and prevents them from falling off during disassembly; a rubber ring seals for dust prevention, improving service life; in the ball spline pair, the spline shaft and the spline pair can perform both sensitive and easy linear motion, and can also perform rotary motion with the shaft and sleeve or the sleeve and shaft. The surface of the push plate 30221 is preferably provided with multiple balls, which are circumferentially distributed on the surface of the plate around the axis of the push plate 30221. The surface of the push plate 30221 has grooves for mating with the balls. The balls rotate within the grooves and protrude from the plate surface to contact the pushing surface of the pusher 10.

[0050] The embodiment also provides a flower-sprinkling process, including the following steps: S1: Feed the granular material into the feed trough 303; S2: The rotating drive 304 drives the rotating shaft 302 to rotate. The granular material first falls to impact the guide plate 401 and then is discharged through the narrow discharge port 402.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
