[0024] (1) In this invention, by setting a pelletizing mechanism and a melting mechanism in combination, on the one hand, large solid plasters can be automatically pelletized, and individual plaster pellets can be melted and then coated in sequence. Compared with the traditional method of melting large solid plasters in a container, this invention does not need to wait until all large solid plasters are melted before coating. The melting and coating of plasters can be carried out in batches and simultaneously, with a high degree of automation and good structural linkage, which improves the production efficiency of plasters. On the other hand, during the melting of individual plaster pellets, the melted part on the outer surface of the plaster pellet can be automatically scraped off, which makes it easier for the unmelted part in the center of the plaster pellet to be heated, shortening the melting time of the plaster pellet and improving the melting efficiency of the plaster pellet.

[0025] (2) In this invention, by combining the scraping component and the powder spraying component, on the one hand, precious medicinal powder can be added to the plaster of a single plaster in sequence. Compared with the traditional method of melting large solid plasters and then adding precious medicinal powder, this invention can ensure that each plaster contains precious medicinal powder, make full use of raw materials, reduce production costs, and avoid the problem that the traditional plaster and precious medicinal powder have a long and uneven mixing time, resulting in different contents of precious medicinal powder in each plaster and different medicinal effects. On the other hand, precious medicinal powder can be sprayed simultaneously during each scraping process to ensure that the contents of precious medicinal powder in each plaster are the same, and that the precious medicinal powder can be distributed in layers in the plaster, thereby improving the medicinal effect of the plaster.

[0026] (3) In this invention, the cover plate assembly and the pusher assembly work together to keep the melted plaster warm and prevent it from solidifying again, making it easier to discharge the plaster; on the other hand, the plaster can be discharged onto the base fabric at equal intervals, making it easier to apply the plaster to the beach.

[0027] In summary, this invention can sequentially melt individual plaster particles before spreading them, scrape off the melted portion from the outer surface of the plaster particles, shorten the melting time of the plaster particles, improve the melting efficiency of the plaster particles, has a high degree of automation, good structural linkage, and can mass-produce plaster patches, thereby improving the production efficiency of enterprises.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1-16 As shown, a granulation and melting device for producing plaster patches includes a granulation mechanism 2, a material transfer mechanism 3, a melting mechanism 4, and a fabric conveying mechanism 5, all mounted on a frame 1.

[0048] The material transfer mechanism 3 includes a first conveying component 31 disposed on the frame 1 and a plurality of material picking components 32 disposed on the first conveying component 31 and used to pick up individual plaster pellets;

[0049] The melting mechanism 4 includes a second conveying component 41 mounted on the frame 1 and running synchronously in the opposite direction to the first conveying component 31; several sets of heat-melting components 42 mounted on the second conveying component 41 for melting plaster particles; two sets of scraping components 43 symmetrically mounted on the heat-melting components 42 for intermittently scraping off the melted portion of the plaster particles; a powder spraying component 44 mounted on the scraping components 43 for intermittently spraying powder into the melted plaster; a cover plate assembly 45 horizontally sliding on the heat-melting component 42; and a pushing component 46 mounted inside the heat-melting component 42 for pushing out the melted plaster.

[0050] It should be noted that the large solid plaster pieces that have been extruded into rectangular shapes after being detoxified are placed into the pelletizing mechanism 2 for pelletizing.

[0051] In this embodiment, the pelletizing mechanism 2 and the melting mechanism 4 work together to automatically granulate large solid plaster pieces and melt each individual piece before spreading it. Compared to the traditional method of melting large solid plaster pieces in a container, this invention does not require waiting for all large solid plaster pieces to melt before spreading. The melting and spreading of the plaster can be carried out in batches simultaneously, resulting in a high degree of automation and good structural linkage, which improves the production efficiency of plaster patches and enables mass production. On the other hand, during the melting process of individual plaster pieces, the melted portion on the outer surface of the plaster piece can be automatically scraped off, facilitating the heating of the unmelted portion in the center of the plaster piece, shortening the melting time, and improving the melting efficiency of the plaster piece.

[0052] In detail, large solid plasters are cut into plaster pellets of the same size by the pelletizing mechanism 2. The first conveying component 31 carries the picking component 32 to pick up individual plaster pellets in sequence. The picking component 32 puts the plaster pellets into the heat-melting component 42 on the second conveying component 41. The scraping component 43 intermittently scrapes off the melted part of the outer surface of the plaster pellets in the heat-melting component 42. At the same time, the powder spraying component 44 intermittently sprays precious medicinal powder into the melted plaster. Then, the pushing component 46 pushes all the melted plaster pellets onto the base fabric on the conveying mechanism 5. The base fabric with the plaster evenly distributed is coated and output for the next process.

[0053] Furthermore, such as Figure 4 and Figure 6-9 As shown, the pelletizing mechanism 2 includes a cutting component 21 disposed on the first conveying frame 312 and a screening component 22 disposed on the cutting component 21;

[0054] The slitting assembly 21 includes a material conveying channel 211 mounted on the first conveying frame 312 via a mounting bracket, a third hydraulic component 213 mounted on the material conveying channel 211 via an ear plate and having a side pressure plate 212 at its output end, a grid-shaped cutter 214 mounted at the output end of the material conveying channel 211, and a fourth hydraulic component 216 mounted on the material conveying channel 211 via an ear plate and having a cutting blade 215 at its output end;

[0055] The screening assembly 22 includes a vibratory plate 221 mounted on the mounting frame and located directly below the output end of the conveying channel 211, a guide bend 222 connected to the bottom of the vibratory plate 221, a temporary storage channel 223 located at the port of the guide bend 222, a strip hole 224 located at the bottom of the temporary storage channel 223 for the material picking needle 322 to pass through, a baffle 225 hinged to the output end of the temporary storage channel 223, and a fourth elastic element 226 located between the baffle 225 and the temporary storage channel 223 via an ear plate and used to drive the baffle 225 to reset.

[0056] It is worth mentioning that the temporary storage channel 223 can only hold one plaster pellet, and the baffle 225 will prevent the plaster pellet from moving forward without external force.

[0057] In this embodiment, the cutting component 21 and the screening component 22 work together to automatically cut large solid plasters into plaster particles of the same size, and output individual plaster particles one by one, which facilitates the transfer and melting of plaster particles.

[0058] In detail, a large solid plaster is placed into the feeding channel 211 of the cutting component 21. The third hydraulic component 213 drives the side pressure plate 212 to push the large solid plaster forward in the feeding channel 211, so that the front end of the large solid plaster is cut into plaster strips of the same specification by the grid cutter 214. Then, the fourth hydraulic component 216 drives the cutter 215 to cut the plaster strips into plaster granules of the same specification. The plaster granules are scattered in the vibrating plate 221, and after vibration, they slide down from the guide tube 222 into the temporary storage channel 223, waiting to be picked up by the picking component 32.

[0059] Furthermore, such as Figure 3-6 and Figure 10 As shown, the first conveying assembly 31 includes a first conveyor frame 312 that is mounted on the frame 1 via a connecting rod and has a first conveyor belt 311.

[0060] The material-taking assembly 32 includes a frame 321 mounted on the first conveyor belt 311, a material-taking needle 322 that passes through and is vertically mounted on the top of the frame 321 for taking plaster pellets, a lifting plate 323 that is horizontally mounted on the lower end of the material-taking needle 322 and has one end that passes through the side of the frame 321, a first elastic member 324 that is mounted between the lifting plate 323 and the top of the frame 321 for resetting the material-taking needle 322, a pusher plate 325 that passes through the material-taking needle 322 and is connected to the frame 321 via an elastic telescopic member, a first limiting track 326 mounted on the first conveyor frame 312 for driving the material-taking needle 322 to take plaster pellets, a second limiting track 327 mounted on the first conveyor frame 312 for driving the material-taking needle 322 to feed plaster pellets into the heat-melting assembly 42, and a third limiting track 328 mounted on the first conveyor frame 312 for driving the pusher plate 325 to push the plaster pellets on the material-taking needle 322 into the heat-melting assembly 42.

[0061] It should be noted that the elastic telescopic component is composed of a telescopic rod and a spring.

[0062] In this embodiment, by using the material taking component 32 and the screening component 22 together, individual plaster particles can be sequentially picked up and transferred to the corresponding heat-melting component 42.

[0063] In detail, when the first conveyor belt 311 carries the picking component 32 to the input end of the temporary storage channel 223, the lifting plate 323 is driven by the first limiting rail 326 to raise the picking needle 322, so that the upper end of the picking needle 322 is inserted into the plaster pellet through the strip hole 224 at the bottom of the temporary storage channel 223. The picking needle 322 and the plaster pellet are moved out from the output end of the temporary storage channel 223, thereby picking up a single plaster pellet. Then, the baffle 225 is reset under the drive of the fourth elastic element 226, continuing to block the output end of the temporary storage channel 223. After the lifting plate 323 is separated from the first limiting rail 326, the picking needle 322 is driven by the first elastic element 324 to descend and reset with the picked plaster pellet.

[0064] Furthermore, such as Figure 11-16 As shown, the second conveying assembly 41 is located directly below the first conveying assembly 31, and includes a second conveying frame 412 that is mounted on the frame 1 via a connecting rod and has a second conveyor belt 411.

[0065] The hot-melting components 42 are evenly distributed on the second conveyor belt 411 and correspond to the positions of the material receiving components 32. They include a bracket 421 on the second conveyor belt 411, a heating box 422 on the top of the bracket 421 and with electric heating plates on its opposite sides, and a receiving pin 423 at the bottom of the heating box 422.

[0066] It should be noted that the electric heating plate is located inside the side wall of the heating box 422 and will not come into contact with the plaster, so it does not need to be cleaned.

[0067] In this embodiment, the combination of the heat-melting component 42 and the material-receiving component 32 enables the corresponding reception of individual plaster particles and the heating and melting of the plaster particles.

[0068] In detail, when the first conveyor belt 311 carrying the material-taking component 32 moves to the position below the first conveyor frame 312, the material-taking component 32 corresponds to the position of the heat-melting component 42 on the second conveyor belt 411 and moves forward synchronously. The end cover 452 of the cover plate component 45 opens under the drive of the fifth limiting rail 454. Then, the lifting plate 323 is driven by the second limiting rail 327 to lower the material-taking needle 322, so that the material-taking needle 322 carries the plaster particles down to the receiving needle 423 in the heating box 422. Then, the push plate... Driven by the third limiting track 328, 325 descends, completely pushing the plaster particles on the picking needle 322 into the heat-melting component 42. After the lifting plate 323 disengages from the second limiting track 327, it first lifts and resets the picking needle 322, so that the picking needle 322 is completely detached from the plaster particles. Then, the pushing plate 325 disengages from the third limiting track 328 and resets, so that the plaster particles are completely transferred to the receiving needle 423 in the heating box 422. Finally, the electric heating plates on both sides of the heating box 422 heat and melt the plaster particles on the receiving needle 423.

[0069] Furthermore, such as Figure 13-16 As shown, the two sets of scraping assemblies 43 are respectively disposed on the side of the electric heating plate of the heating box 422. Each assembly includes an L-shaped support plate 431 that is raised and lowered on the outer wall of the heating box 422 via a limiting groove; a first hydraulic component 432 that is horizontally disposed on the L-shaped support plate 431 and has a mounting plate at its output end; two sets of hanging rods 433 that pass through the mounting plate; a scraper 434 disposed between the lower ends of the two hanging rods 433; a connecting plate disposed between the upper ends of the two hanging rods 433; a second hydraulic component 435 disposed between the connecting plate and the mounting plate; an extension rod 436 disposed on the L-shaped support plate 431; a fourth limiting rail 437 disposed on the second conveying frame 412 and used to drive the scraping assembly 43 to rise and fall via the extension rod 436; and a second elastic component 438 disposed between the L-shaped support plate 431 and the heating box 422 and used to drive the scraping assembly 43 to reset.

[0070] The powder spraying assembly 44 includes an airbag 441 disposed on the mounting plate and containing fine drug powder, and a nozzle 442 disposed at the bottom of the mounting plate and connected to the airbag 441 via a hose.

[0071] In this embodiment, the scraping component 43 and the powder spraying component 44 work together to, on the one hand, add precious medicinal powder to the plaster of a single plaster in sequence. Compared with the traditional method of melting large solid plaster pieces before adding precious medicinal powder, this invention ensures that each plaster contains precious medicinal powder, making full use of raw materials, reducing production costs, and avoiding the problem of long and uneven mixing time between traditional plasters and precious medicinal powder, which leads to different contents of precious medicinal powder in each plaster and thus different medicinal effects. On the other hand, precious medicinal powder can be sprayed simultaneously during each scraping process to ensure that the content of precious medicinal powder in each plaster is the same, and that the precious medicinal powder can be distributed in layers in the plaster, thereby improving the medicinal effect of the plaster.

[0072] In detail, when the second conveyor belt 411 carrying the heat-melting component 42 moves to the position of the fourth limiting track 437, the fourth limiting track 437 drives the L-shaped support plate 431 to rise, causing the scraper 434 to rise to the top of the heating box 422. Then, the first hydraulic component 432 intermittently moves the scraper 434 horizontally towards the plaster pellets a specified distance, and the second hydraulic component 435 intermittently drives the scraper 434 to descend via the suspension rod, causing the scraper 434 to scrape off the melted part of the outer surface of the plaster pellets in sequence, causing the melted plaster to detach from the plaster pellets and descend. As the scraper 434 descends to the bottom of the heating box, the connecting plate descends and compresses the airbag 441, causing the precious medicinal powder inside the airbag 441 to be sprayed from the nozzle 442 into the plaster at the bottom of the heating box, thus completing the melting of the plaster particles. Then, the first hydraulic component 432 and the second hydraulic component 435, along with the scraper 434, leave the heating box 422. When the second conveyor belt 411 carries the heat-melting component 42 away from the position of the fourth limit track 437, the L-shaped support plate 431, along with the scraper 434, descends to reset, ready for the next use.

[0073] Furthermore, such as Figure 4 and Figure 11-16 As shown, the cover plate assembly 45 includes an L-shaped connecting plate 451 disposed on the outer side wall of the heating box 422 via an elastic telescopic member, an end cap 452 disposed on the L-shaped connecting plate 451, a drive rod 453 disposed on the L-shaped connecting plate 451, a fifth limiting rail 454 disposed on the first conveyor frame 312 for driving the end cap 452 to open, and a sixth limiting rail 455 disposed on the bottom plate 11 of the frame 1 for driving the end cap 452 to open.

[0074] The feeding assembly 46 includes a top plate 461 that is slidably disposed inside the heating box 422 and passes through the receiving needle 423; a top rod 462 disposed at the bottom of the top plate 461 and whose lower end passes through the bottom of the heating box 422; a transmission rod 463 disposed at the lower end of the top rod 462 and whose one end passes through the side of the bracket 421; a third elastic member disposed between the transmission rod 463 and the bracket 421 and used to drive the top plate 461 to reset; and a seventh limiting track 464 disposed on the second conveying frame 412 and used to drive the top plate 461 to push the melted plaster out of the heating box 422.

[0075] It is worth mentioning that the end cap 452 is coated with existing heat-insulating material to keep the melted plaster in the heating box 422 warm and prevent the melted plaster from solidifying again.

[0076] It should be noted that the first conveyor belt 311 and the second conveyor belt 411 rotate synchronously in opposite directions via belt drive. The frame 1 is equipped with a stepper motor 12 for driving the first conveyor belt 311, ensuring that the material picking component 32 on the first conveyor belt 311 and the heat melting component 42 on the second conveyor belt 411 can always correspond to each other in position during the movement.

[0077] In this embodiment, the cover plate assembly 45 and the pusher assembly 46 work together to keep the melted plaster in the heating box 422 warm, prevent the melted plaster from solidifying again, and facilitate the discharge of the plaster from the heating box 422. On the other hand, the plaster in the heating box 422 can be discharged onto the base fabric at equal intervals, which facilitates the plaster application.

[0078] In detail, when the second conveyor belt 411 carries the heat-melting component 42 forward and moves away from the position of the fifth limiting track 454, the end cover 452 is driven by the elastic telescopic member to cover the top of the heating box 422, keeping the inside of the heating box 422 warm and preventing the plaster in the heating box 422 from dripping when the heat-melting component 42 moves to the position below the second conveyor frame 42. When the heat-melting component 42 moves to the position of the sixth limiting track 455, the end cover 452 opens again. At the same time, the transmission rod 463 of the pushing component 46 is driven by the seventh limiting track 464 to bring the top plate 461 down, so that the top plate 461 discharges all the plaster in the heating box 422 onto the base fabric that runs synchronously with the second conveyor belt 411.

For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0081] Furthermore, such as Figure 1-3 and Figure 11-12 As shown, the fabric conveying mechanism 5 includes a conveying roller 51 mounted on the frame 1 for conveying the base fabric on the base plate 11 forward, and a traction roller 52 mounted on the frame 1 for pulling the oil paper onto the base fabric for lamination.

[0082] It is worth mentioning that the conveying roller 51 and the traction roller 52 are both driven by belts and rotate synchronously and in the same direction with the second conveyor belt 411, ensuring that the plaster in the heat-melting component 42 can be applied to the base fabric at equal intervals.

[0083] Work process:

[0084] Large solid plasters are cut into plaster pellets of the same size by the pelletizing mechanism 2 and output one by one. The first conveying component 31 carries the picking component 32 to pick up individual plaster pellets in sequence. The picking component 32 puts the plaster pellets into the heat-melting component 42 on the second conveying component 41. The scraping component 43 scrapes off the melted part of the outer surface of the plaster pellets in the heat-melting component 42 intermittently. At the same time, the powder spraying component 44 intermittently sprays precious medicinal powder into the melted plaster. Then, the pushing component 46 pushes all the melted plaster pellets onto the base fabric on the conveying mechanism 5. The base fabric with the plaster evenly distributed is output after being coated, ready for the next process.
