A marigold flower pulverizing and granulation device and its processing technology

Abstract

This invention relates to the field of marigold pulverization technology, specifically a marigold pulverization and granulation device and its processing technology. It mainly includes a support frame with a pulverizing box mounted on its top surface. It also includes: a pulverizing mechanism located inside the pulverizing box; a filtering mechanism located above the support frame; a striking mechanism located inside the support frame; and a dispersing mechanism located above the support frame. The equipment is driven by a rotating shaft, pulleys, sprockets, and chains to rotate an external gear ring synchronously with a filter cylinder. The pulverized marigold material falls into the filter cylinder, where a conveying spiral tumbles and transports the material, preventing fine powder from being trapped by large petals. Fine material falls through the screen holes in the cylinder wall, while large impurities are discharged from the outlet frame. During operation, protrusions cooperate with elastic elements to push an arc-shaped plate, causing the striking strip to swing back and forth. The striking head continuously vibrates the filter cylinder, clearing blocked screen holes, accelerating the separation of qualified powder, resulting in more thorough sieving, and effectively improving material filtration accuracy and continuous processing efficiency.

Description

Technical Field

[0001] This invention relates to the field of marigold flower pulverization technology, specifically to a marigold flower pulverizing and granulation device and its processing technology. Background Technology

[0002] Marigolds are annual herbaceous plants belonging to the genus *Mallotus* in the family Asteraceae. Their flowers are rich in natural lutein-like plant pigments, which are safe and non-toxic and widely used as natural colorants in beverages, frozen drinks, pastries, and oily foods. Before industrial extraction of marigold pigments, the harvested marigold flowers need to undergo pre-treatment, crushing, and granulation. Intact petals have loose fibers and large pores, resulting in low extraction efficiency when extracted directly. Therefore, specialized crushing equipment is needed to thoroughly break down and refine the flowers, disrupting the fibrous structure of the petals. The granules are then extruded into compact particles, reducing material volume, increasing the pigment leaching rate, minimizing processing losses, and ensuring the yield and quality of subsequent pigment extraction.

[0003] When marigolds are crushed by a crushing device, the marigolds are fed into the equipment, and the high-speed rotating crushing blades cut and crush the flowers. The crushed material is then screened through a filter plate to select powder that meets the specifications. However, the existing structure only relies on a single layer of filter plate to complete the grading and filtration. The marigold fibers are light and soft, and the fine qualified powder is easily wrapped by large petals. The powder is not completely screened and is conveyed out with the large particles, resulting in incomplete screening of the material. This problem will significantly reduce the crushing and filtration accuracy, directly reducing the processing quality and continuous production efficiency of the entire process. Summary of the Invention

[0004] The purpose of this invention is to provide a marigold flower pulverizing and granulation device and its processing technology to solve the problems mentioned in the background art.

The inner wall of the concave strip is hinged with a striking strip, and a concave block is provided below the fixed strip.

[0010] The dispersing mechanism is located above the support frame and includes two sets of dispersing strips inside the filter cartridge. A connecting plate is fixedly installed at one end of each dispersing strip.

[0011] Preferably, the outer wall of the rotating shaft is fixedly connected to the inner wall of multiple crushing blades, and gears are fixedly installed on the outer walls of the two rotating shafts respectively, with the two gears meshing together.

[0012] Preferably, a fixed frame is fixedly installed on the side of the support frame, a connecting frame is fixedly installed on the top surface of the fixed frame, a motor is fixedly installed on the inner wall of the connecting frame, and the output rod of the motor is fixedly connected to one end of the rotating shaft.

[0013] Preferably, two sets of mounting brackets are fixedly installed on the top surface of the support frame. Rollers are rotatably installed on the inner wall of mounting bracket one, and the rollers are in rolling connection with the inside of the locking ring. Mounting bracket two and bearing seat are fixedly installed on the top surface of the support frame. A connecting shaft is rotatably installed on the inner wall of mounting bracket two and the inner wall of bearing seat through the bearing. A sprocket is fixedly installed on the outer wall of the connecting shaft.

[0014] Preferably, the sprocket is connected to the external gear ring via a chain drive, and pulleys are fixedly installed on the outer wall of the connecting shaft and the outer wall of the rotating shaft. The outer walls of the two pulleys are connected by a belt drive. A feeding frame is installed inside the support frame, and a discharge frame is installed on the side of the support frame.

[0015] Preferably, a striking head is fixedly installed at one end of the striking strip, the outer wall of the striking head is movably connected to the filter cartridge, a transverse groove is provided on the inner wall of the concave block, and an adjusting column is fixedly installed at one end of the striking strip, with the outer wall of the adjusting column slidably connected to the inner wall of the transverse groove.

[0016] Preferably, two fixing columns are fixedly installed on the top surface of the concave block. The upper end of the fixing column slides through the fixing strip and is fixedly installed with an arc plate. An elastic element is movably installed on the outer wall of the fixing column. The two ends of the elastic element abut against the bottom surface of the arc plate and the top surface of the fixing strip, respectively. Multiple protrusions are fixedly installed on the outer wall of the filter cartridge. The top surface of the arc plate is slidably connected to the outer wall of the filter cartridge and the outer wall of the protrusions.

[0017] Preferably, a connecting strip is fixedly installed on the bottom surface of the connecting plate, a T-shaped block is fixedly installed on the side of the connecting strip, a T-shaped groove is provided on the side of the fixing strip, and the inner wall of the T-shaped groove is slidably connected to the outer wall of the T-shaped block.

[0018] Preferably, the concave block has a groove on its side, and a cylinder is fixedly installed on the side of the connecting strip, with the outer wall of the cylinder slidingly connected to the inner wall of the groove.

[0019] A processing technology for crushing and granulating marigold flowers includes the following steps:

[0020] Step 1: Feeding and crushing

[0021] S1. Marigold flowers are added from the feed hopper and crushed by the crushing blades. The crushed marigold powder enters the filter cylinder from the discharge pipe.

[0022] Step 2: Disperse

[0023] S2. During the process of the crushed marigold flower powder entering the filter cylinder from the discharge pipe, the two sets of dispersing strips move back and forth in opposite directions. The dispersing strips fully break down the clump-together petal fibers, preventing fine qualified powder from being wrapped by large petals.

[0024] Step 3: Filter delivery

[0025] S3. The dispersed marigold pollen falls into the filter cylinder. The filter cylinder and the conveying screw rotate synchronously to filter and convey the marigold pollen. Fine qualified powder falls from the filter holes of the filter cylinder, while large petals are discharged from the discharge frame.

[0026] S4. The striking bar swings back and forth in an arc, and the filter cylinder is vibrated by the striking, which allows the fine qualified powder inside the filter cylinder to fall quickly, ensuring more thorough screening of materials.

[0027] Step 4: Humidify and adjust the temperature

[0028] S5. Add an appropriate amount of conditioning water to the crushed powder, mix evenly, adjust the material viscosity, provide a binding basis for granulation, and avoid the dry material from being loose and not forming.

[0029] Step 5: Extrusion Granulation

[0030] S6. The conditioning powder is conveyed to the pelletizing die roller assembly, where it is extruded under high pressure to form columnar marigold granules.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] This invention utilizes a rotating shaft and pulley to drive the connecting shaft and sprocket. The sprocket, via a chain, drives the outer gear ring and filter cylinder to rotate. The crushed marigold particles fall from the discharge pipe into the filter cylinder. The conveying screw inside the filter cylinder rotates with it. Simultaneously, the rotation of the filter cylinder and the conveying screw causes the marigold particles inside to tumble and be conveyed. Fine, qualified powder is less likely to be trapped by large petals and falls out of the filter holes in the filter cylinder. Large petals are discharged from the discharge frame. During the rotation of the drum, multiple protrusions rotate, repeatedly pressing the arc-shaped plate and cooperating with the elastic element. The arc-shaped plate moves up and down, causing the fixed column and concave block to move up and down. The transverse groove on the concave block causes the adjusting column and the striking bar to swing back and forth in an arc, causing the striking head to swing back and forth in an arc to strike and vibrate the bottom of the filter cylinder. This allows the fine, qualified powder inside the filter cylinder to fall out quickly, ensuring more thorough material screening, significantly improving the crushing and filtration accuracy, and directly improving the processing quality and continuous production efficiency of the entire process.

[0033] As the concave block moves downwards and reciprocates with the structure, the inclined groove on the concave block synchronously drives the two sets of cylinders and connecting strips to reciprocate relative to each other. The two sets of connecting strips pull the connecting plate respectively, causing the two sets of dispersing strips to move back and forth in opposite directions. As the crushed marigold powder falls from the discharge pipe into the filter cartridge, the two sets of dispersing strips moving in opposite directions continuously disperse and comb the falling material, fully breaking down the clumps of petal fibers, preventing fine qualified powder from being wrapped by large petals, allowing coarse and fine materials to be separated quickly, reducing screen clogging, effectively improving the material screening and filtration accuracy, stabilizing the material processing quality of the entire processing procedure, and significantly improving the continuous production efficiency of the equipment.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0051] like Figures 1-9As shown, this application provides a marigold flower crushing and granulation device, including: a support frame 1, a crushing box 101 installed on the top surface of the support frame 1, a feeding hopper 102 installed on the top of the crushing box 101, and a discharge pipe 103 installed at the bottom of the crushing box 101.

[0052] The crushing mechanism 2 is located inside the crushing box 101. The crushing mechanism 2 includes multiple crushing blades 205 located inside the crushing box 101. Two rotating shafts 204 are rotatably mounted on the side of the crushing box 101 via bearings.

[0053] Specifically, such as Figure 4 As shown, the outer wall of the rotating shaft 204 is fixedly connected to the inner wall of multiple crushing blades 205. Gears 206 are fixedly installed on the outer walls of the two rotating shafts 204 respectively. The two gears 206 are meshed and connected. Multiple crushing blades 205 are provided on both rotating shafts 204.

[0054] In this embodiment: the pulverizing blade 205 is used to quickly pulverize the marigold flowers, thereby improving the efficiency of marigold flower pulverization.

[0055] Specifically, such as Figure 2 As shown, a fixed frame 201 is fixedly installed on the side of the support frame 1, a connecting frame 202 is fixedly installed on the top surface of the fixed frame 201, a motor 203 is fixedly installed on the inner wall of the connecting frame 202, and the output rod of the motor 203 is fixedly connected to one end of the rotating shaft 204.

[0056] In this embodiment: the motor 203 is fixed by the fixed frame 201 and the connecting frame 202, so that the motor 203 is connected more stably, and the motor 203 drives a rotating shaft 204 to rotate.

[0057] The filter mechanism 3 is located above the support frame 1. The filter mechanism 3 includes a filter cylinder 304 located above the support frame 1. A conveying screw 314 is fixedly installed on the inner wall of the filter cylinder 304, and a locking ring 303 and an external toothed ring 307 are fixedly installed on the outer wall of the filter cylinder 304.

[0058] Specifically, such as Figure 6 As shown, two sets of mounting brackets 301 are fixedly installed on the top surface of the support frame 1. Rollers 302 are rotatably installed on the inner wall of mounting bracket 301. The rollers 302 are rolledly connected to the locking ring 303. Mounting bracket 308 and bearing seat 311 are fixedly installed on the top surface of the support frame 1. A connecting shaft 312 is rotatably installed on the inner wall of mounting bracket 308 and the inner wall of bearing seat 311 through a bearing. A sprocket 309 is fixedly installed on the outer wall of the connecting shaft 312.

[0059] In this embodiment: the roller 302 is provided, and the roller 302 supports the locking ring 303 and limits the locking ring 303 at the same time, so that the locking ring 303 and the filter cylinder 304 are not prone to displacement when rotating, thus ensuring the stability of the filter cylinder 304 when rotating and filtering. The filter cylinder 304 rotates together with the conveying screw 314, and the filter cylinder 304 filters and conveys marigold pollen.

[0060] Specifically, such as Figures 1-6 As shown, the sprocket 309 is connected to the external gear ring 307 via the chain 310. The outer wall of the connecting shaft 312 and the outer wall of the rotating shaft 204 are both fixedly installed with pulleys 313. The outer walls of the two pulleys 313 are connected by belt drive. The support frame 1 is equipped with a feeding frame 306 inside. The support frame 1 is equipped with a discharge frame 305 on the side. The discharge frame 305 is located on one side of the filter cartridge 304 and is set in an arc shape.

[0061] In this embodiment: the rotating shaft 204 rotates, the pulley 313 rotates and drives the connecting shaft 312 and the sprocket 309 to rotate. The sprocket 309 drives the outer toothed ring 307 and the filter cylinder 304 to rotate through the chain 310. While the filter cylinder 304 rotates, it drives the marigold powder inside to tumble, so that the fine qualified powder can fall off quickly, ensuring that the material screening is more thorough.

[0062] The striking mechanism 4 is located inside the support frame 1. The striking mechanism 4 includes a concave strip 401 and a fixing strip 404 fixedly installed on the inner wall of the support frame 1. A striking strip 402 is hinged to the inner wall of the concave strip 401, and a concave block 405 is provided below the fixing strip 404.

[0063] Specifically, such as Figures 5-9 As shown, a striking head 403 is fixedly installed at one end of the striking bar 402. The outer wall of the striking head 403 is movably connected to the filter cartridge 304. A transverse groove 410 is provided on the inner wall of the concave block 405. An adjusting column 411 is fixedly installed at one end of the striking bar 402. The outer wall of the adjusting column 411 is slidably connected to the inner wall of the transverse groove 410.

[0064] In this embodiment: when the concave block 405 moves up and down, the transverse groove 410 on the concave block 405 drives the adjusting column 411 and the striking bar 402 to swing back and forth in an arc, which in turn drives the striking head 403 to swing back and forth in an arc and strike the filter cylinder 304. The filter cylinder 304 vibrates, which further allows fine qualified powder to fall off quickly, ensuring that the material screening is more thorough.

[0065] Specifically, such as Figures 6-9As shown, two fixing posts 406 are fixedly installed on the top surface of the concave block 405. The upper end of the fixing post 406 slides through the fixing strip 404 and is fixedly installed with an arc plate 408. An elastic element 407 is movably installed on the outer wall of the fixing post 406. The two ends of the elastic element 407 abut against the bottom surface of the arc plate 408 and the top surface of the fixing strip 404, respectively. Multiple protrusions 409 are fixedly installed on the outer wall of the filter cartridge 304. The top surface of the arc plate 408 is slidably connected to the outer wall of the filter cartridge 304 and the outer wall of the protrusions 409.

[0066] In this embodiment: when the filter cylinder 304 rotates, the multiple protrusions 409 on the filter cylinder 304 press the arc plate 408, and the arc plate 408 cooperates with the elastic element 407, so that the arc plate 408, the fixed column 406 and the concave block 405 move up and down reciprocally.

[0067] The dispersion mechanism 5 is located above the support frame 1. The dispersion mechanism 5 includes two sets of dispersion strips 505 located inside the filter cartridge 304. A connecting plate 504 is fixedly installed at one end of the dispersion strip 505. The two sets of dispersion strips 505 are arranged in an arc shape and are staggered.

[0068] Specifically, such as Figure 8 As shown, a connecting strip 503 is fixedly installed on the bottom surface of the connecting plate 504, and a T-shaped block 502 is fixedly installed on the side of the connecting strip 503. A T-shaped groove 501 is provided on the side of the fixing strip 404, and the inner wall of the T-shaped groove 501 is slidably connected to the outer wall of the T-shaped block 502.

[0069] In this embodiment: the T-shaped groove 501 limits the T-shaped block 502, making the movement of the T-shaped block 502 and the connecting strip 503 more stable, and the two dispersing strips 505 further disperse the crushed marigold pollen.

[0070] Specifically, such as Figures 8-9 As shown, the concave block 405 has a groove 507 on its side, and a cylinder 506 is fixedly installed on the side of the connecting strip 503. The outer wall of the cylinder 506 is slidably connected to the inner wall of the groove 507.

[0071] In this embodiment: when the concave block 405 moves through the inclined groove 507, the cylindrical 506 moves through the inclined groove 507, which in turn moves the connecting strip 503.

[0072] A processing technology for crushing and granulating marigold flowers includes the following steps:

[0073] Step 1: Feeding and crushing

[0074] S1. Marigold flowers are added from the feed hopper 102 and crushed by the crushing blade 205. The crushed marigold flower powder enters the filter cylinder 304 from the discharge pipe 103.

[0075] Step 2: Disperse

[0076] S2. During the process of the crushed marigold flower powder entering the filter cylinder 304 from the discharge pipe 103, the two sets of dispersing strips 505 move back and forth in opposite directions. The dispersing strips 505 fully break up the clump-together petal fibers to prevent fine qualified powder from being wrapped by large petals.

[0077] Step 3: Filter delivery

[0078] S3. The dispersed marigold pollen falls into the filter cylinder 304. The filter cylinder 304 and the conveying screw 314 rotate synchronously to filter and convey the marigold pollen. Fine qualified powder falls from the filter holes of the filter cylinder 304, and large petals are discharged from the discharge frame 305.

[0079] S4. The striking bar 402 swings back and forth in an arc, and the filter cylinder 304 is subjected to the striking vibration, which allows the fine qualified powder inside the filter cylinder 304 to fall quickly, ensuring that the material screening is more thorough.

[0080] Step 4: Humidify and adjust the temperature

[0081] S5. Add an appropriate amount of conditioning water to the crushed powder, mix evenly, adjust the material viscosity, provide a binding basis for granulation, and avoid the dry material from being loose and not forming.

[0082] Step 5: Extrusion Granulation

[0083] S6. The conditioning powder is conveyed to the pelletizing die roller assembly, where it is extruded under high pressure to form columnar marigold granules.

[0084] The specific steps are as follows: Motor 203 is turned on, and marigold flowers are added from the feed hopper 102. Motor 203 drives a single rotating shaft 204 to rotate. Through the cooperation of two gears 206, the two rotating shafts 204 and multiple pulverizing blades 205 rotate, pulverizing the marigold flowers. The pulverized marigold flower powder falls into the filter cartridge 304 through the discharge pipe 103. The rotating shafts 204 drive the connecting shaft 312 and the sprocket 309 to rotate via pulley 313. The sprocket 309 drives the external gear ring 307 and the filter cartridge 304 to rotate via chain 310. The filter cartridge 304 drives multiple protrusions 409 to rotate. The protrusions 409 repeatedly press the arc-shaped plate 408 and cooperate with the elastic element 407. The arc-shaped plate 408 moves up and down, driving the fixed column 406 and the concave block 405 to move up and down. The inclined groove 507 on the concave block 405 synchronously drives the two sets of cylinders 506 and connecting strips 503 to move back and forth relative to each other. The two sets of connecting strips 503 respectively pull the connecting plate 504, driving the two sets of dispersing strips 505 to move back and forth in opposite directions. The crushed marigold powder falls from the discharge pipe 103 into the filter cartridge 304. During the flow of the filter cartridge 304, two sets of dispersing strips 505 moving in opposite directions continuously break up and comb the falling material, fully disintegrating the clumps of petal fibers. This prevents fine, qualified powder from being encased by large petals, allowing for rapid separation of coarse and fine materials, reducing sieve clogging. The crushed marigold particles fall into the filter cartridge 304, where the conveying screw 314 rotates. Simultaneously, the rotation of both the filter cartridge 304 and the conveying screw 314 causes the marigold particles inside to tumble and be conveyed, preventing fine, qualified powder from being trapped by large petals. Fine, qualified powder falls from the filter holes of the filter cylinder 304, while large petals are discharged from the discharge frame 305. At the same time, as the concave block 405 moves up and down, the transverse groove 410 on the concave block 405 drives the adjusting column 411 and the striking bar 402 to swing back and forth in an arc, which in turn drives the striking head 403 to swing back and forth in an arc to strike and vibrate the bottom of the filter cylinder 304. This allows the fine, qualified powder inside the filter cylinder 304 to fall down quickly, ensuring more thorough material screening, greatly improving the crushing and filtration accuracy, and directly improving the processing quality and continuous production efficiency of the entire process.

[0085] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.

10. A processing method for crushing and granulating marigold flowers, using a marigold flower crushing and granulating device according to any one of claims 1-9, comprising the following steps: Step 1: Feeding and crushing S1. Marigold flowers are added from the feed hopper (102) and crushed by the crushing blade (205). The crushed marigold flower powder enters the filter cylinder (304) from the discharge pipe (103). Step 2: Disperse S2. During the process of the crushed marigold flower powder entering the filter cylinder (304) from the discharge pipe (103), the two sets of dispersing strips (505) move back and forth in opposite directions. The dispersing strips (505) fully break down the clump-together petal fibers to prevent fine qualified powder from being wrapped by large petals. Step 3: Filter delivery S3. The dispersed marigold pollen falls into the filter cylinder (304). The filter cylinder (304) and the conveying screw (314) rotate synchronously to filter and convey the marigold pollen. Fine qualified powder falls from the filter holes of the filter cylinder (304), and large petals are discharged from the discharge frame (305). S4. The striking bar (402) swings back and forth in an arc, and the filter cylinder (304) is subjected to the striking vibration, so that the fine qualified powder inside the filter cylinder (304) can fall quickly, ensuring that the material screening is more thorough. Step 4: Humidify and adjust the temperature S5. Add an appropriate amount of conditioning water to the crushed powder, mix evenly, adjust the material viscosity, provide a binding basis for granulation, and avoid the dry material from being loose and not forming. Step 5: Extrusion Granulation S6. The conditioning powder is conveyed to the pelletizing die roller assembly, where it is extruded under high pressure to form columnar marigold granules.
