DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] By setting the first cleaning component 3a and the second cleaning component 3b at the end of the conveyor belt 2, the surface of the conveyor belt 2 after the product transmission is completed can be cleaned to prevent the debris from following the conveyor belt into the drying mechanism 4 for drying again, causing the debris to be dried and the food to be contaminated.

[0033] The first cleaning component 3a can remove most of the debris. When the first cleaning component 3a encounters harder and larger block debris, the first cleaning component 3a can cut and crush it, and the first cleaning component 3a has a certain range of motion to ensure that the first scraper 3a2 will not get stuck during the scraping work; the second cleaning component 3b can thoroughly remove the remaining debris adhering to the surface of the conveyor belt 2 to ensure that the surface of the conveyor belt 2 remains clean when loading.

[0034] During work, the staff sends the powdered or broken food to the starting end of the conveyor belt 2 and transmits it through the conveyor belt 2. The powdered or broken food enters the first drying chamber 4a and the second drying chamber 4b in turn for drying. The first drying chamber 4a performs preliminary drying on the powdered or broken food. When the preliminary drying is completed, the powdered or broken food enters the connecting channel 4c. The compacting mechanism 5 located on the connecting channel 4c compacts the powdered or broken food to form a mass, and then passes through the second drying chamber 4b for secondary heating and drying, which not only realizes the drying function, but also enables the discharged food to be in a formed block shape, which is beneficial to the subsequent transportation and packaging processes. When the conveyor belt 2 is transmitting, powdered or broken food residues will remain on the surface. The block-shaped products are first transported out of the equipment through the end of the conveyor belt 2, and then the surface of the conveyor belt 2 is cleaned by the first cleaning component 3a and the second cleaning component 3b installed at the end of the conveyor belt 2.

[0035] Further, such as Figure 7 As shown: the first cleaning component 3a also includes a first connecting plate 3a4 and a tension spring 3a5. The first connecting plate 3a4 is fixedly mounted on the first mounting frame 3a3. The length direction of the first connecting plate 3a4 is perpendicular to the transmission direction of the conveyor belt 2. Both ends of the first connecting plate 3a4 are fixedly mounted on the side walls of the first mounting frame 3a3. The hinged end of the first scraper 3a1 is located below the first connecting plate 3a4. The tension spring 3a5 is arranged between the first scraper 3a1 and the first connecting plate 3a4. The top end of the tension spring 3a5 is fixedly connected to the side wall of the first connecting plate 3a4, and the bottom end of the tension spring 3a5 is fixedly connected to the side wall of the first scraper 3a1.

[0036] The first scraper 3a1 is hingedly mounted on the first mounting frame 3a3 through the first mounting frame 3a3, and the side wall of the first scraper 3a1 is connected to the first connecting plate 3a4 through the tension spring 3a5, so that the first scraper 3a1 has a certain elasticity, and thus the first scraper 3a2 has a certain elastic force when scraping off food residues. When encountering harder and larger food residues, the first connecting plate 3a4 is lengthened to make the first scraper 3a1 rotate a certain angle around the hinged end, so that the first scraper 3a2 can easily scrape off part of the food residues, providing a basis for subsequent thorough cleaning.

[0037] Further, such as Figure 8-9 As shown: the second cleaning component 3b also includes a second connecting plate 3b4, the second connecting plate 3b4 is fixedly mounted on the second mounting frame 3b3, the length direction of the second connecting plate 3b4 is perpendicular to the transmission direction of the conveyor belt 2, the top end of the second connecting plate 3b4 is fixedly connected to the side wall of the second scraper 3b1, the second scraper 3b2 is an arc-shaped scraping head, and the inner arc side of the second scraper 3b2 points to the end of the conveyor belt 2.

[0038] The second scraper 3b1 is fixed to the second mounting frame 3b3 by the second connecting plate 3b4, so that the second scraper 3b2 at the end of the second scraper 3b1 is always in close contact with the lower surface of the conveyor belt 2, and the second scraper 3b2 is designed as an arc-shaped scraping head, so that the debris stubbornly adhering to the surface of the conveyor belt 2 can be completely removed, and the scraped debris can be guided to the side wall of the second scraper 3b1 by the arc-shaped scraping head, and the debris falls along the inclined arc of the second scraper 3b1, so as to facilitate the subsequent collection of the debris.

[0039] Further, such as Figure 10-11 As shown: the cleaning mechanism 3 also includes a third cleaning component 3c, which is arranged just above the end of the conveyor belt 2. The third cleaning component 3c includes a third scraper 3c4 that intermittently scrapes the surface of the conveyor belt 2. The length direction of the third scraper 3c4 is perpendicular to the transmission direction of the conveyor belt 2.

[0040] The third cleaning component 3c also includes a first servo motor 3c1, a reducer 3c2, a rotating roller 3c3 and a third mounting frame 3c5. The third mounting frame 3c5 is fixedly mounted on the frame 1. The rotating roller 3c3 is horizontally arranged directly above the conveyor belt 2. The axial direction of the rotating roller 3c3 is perpendicular to the transmission direction of the conveyor belt 2. Both ends of the rotating roller 3c3 are axially connected to the third mounting frame 3c5. The reducer 3c2 and the first servo motor 3c1 are both arranged on a side wall of the third mounting frame 3c5. The output end of the first servo motor 3c1 is transmission-connected to the input end of the reducer 3c2. The output end of the reducer 3c2 is transmission-connected to one end of the rotating roller 3c3. The third scraper 3c4 is fixedly mounted on the outer side wall of the rotating roller 3c3.

[0041] The third cleaning component 3c can perform scraping operations at two places where the compacted materials have been completed, and the third scraper 3c4 can gradually sweep the debris in the middle of the conveyor belt 2 to both sides, so as to facilitate the subsequent debris unloading process and realize the cleaning of the debris on the surface of the conveyor belt 2 between the two compacted products, so as to reduce the interference of the debris when receiving the products subsequently, and avoid the debris affecting the product quality.

[0042] During operation, the output of the first servo motor 3c1 drives the output of the reducer 3c2, and the output of the reducer 3c2 drives the rotating roller 3c3 connected thereto to rotate, and the rotating roller 3c3 drives the third scraper 3c4 fixedly mounted on its outer wall to rotate synchronously. Specifically, when the rotating roller 3c3 rotates, the tangential movement direction of the lowermost outer wall of the rotating roller 3c3 is opposite to the transmission direction of the conveyor belt 2, thereby driving the third scraper 3c4 to clean the surface of the conveyor belt 2.

[0043] There are two third scrapers 3c4, which are symmetrically installed on the outer wall of the rotating roller 3c3. The middle part of the third scraper 3c4 protrudes outward along the direction of the conveyor belt 2 close to the starting end, and the bottom edges of the third scraper 3c4 can fit with the upper surface of the conveyor belt 2.

[0044] The third scraper 3c4 can gradually remove the debris between the two compacted products. During the rotation of the third scraper 3c4, the debris on the surface of the conveyor belt 2 is gradually pushed from the middle position to the outside and finally falls out of the conveyor belt 2.

[0045] Further, such as Figure 3 and Figure 5-6 As shown: the cleaning mechanism 3 also includes a waste chip recovery box 3d, a blanking recovery guide rail 3e and an inclined material guide plate 3f. The waste chip recovery box 3d is fixedly installed on the frame 1, and the waste chip recovery box 3d is located directly below the end of the conveyor belt 2. There are two blanking recovery guide rails 3e, and the two blanking recovery guide rails 3e are horizontally installed on both sides of the conveyor belt 2 respectively. The length direction of the blanking recovery guide rail 3e is consistent with the transmission direction of the conveyor belt 2. There are two inclined material guide plates 3f, and the two inclined material guide plates 3f are respectively obliquely installed in the two blanking recovery guide rails 3e, and the higher end of the inclined material guide plate 3f is located on the side of the blanking recovery guide rail 3e close to the starting end of the conveyor belt 2.

[0046] The debris scraped off the third cleaning component 3c can be collected through the material recovery guide rail 3e. Since the third scraper 3c4 pushes the debris outward from both sides, the material recovery guide rail 3e installed on both sides of the conveyor belt 2 can concentrate all the fallen materials inside the material recovery guide rail 3e, and the debris in the material recovery guide rail 3e is transported through the inclined guide plate 3f arranged inside the material recovery guide rail 3e, so that the debris moves forward along the length direction of the material recovery guide rail 3e until it falls into the waste chip recovery box 3d to complete the collection process.

[0047] Further, such as Figure 12-13As shown: the compaction mechanism 5 also includes a compaction component 5a and a resistance bearing component 5b, the compaction component 5a is vertically fixedly installed on the connecting channel 4c, the output end of the compaction component 5a is horizontally arranged in the connecting channel 4c, the resistance bearing component 5b is arranged in the conveyor belt 2, the output end of the resistance bearing component 5b is located in the conveyor belt 2, and the output end of the resistance bearing component 5b is located directly below the output end of the compaction component 5a.

[0048] The compaction component 5a includes a first linear drive 5a1 and a pressure plate 5a2. The first linear drive 5a1 is vertically fixedly installed at the top of the connecting channel 4c, and the pressure plate 5a2 is horizontally arranged directly below the connecting channel 4c. The output end of the first linear drive 5a1 is fixedly connected to the top of the pressure plate 5a2, and a rectangular forming groove 5a3 is provided at the bottom end of the pressure plate 5a2.

[0049] The output of the first linear drive 5a1 drives the pressing plate 5a2 fixedly connected thereto to move downward, and the pressing plate 5a2 presses and shapes the food pile in the connecting channel 4c, and the finished shape of the compacted food can be defined by the rectangular molding groove 5a3.

[0050] During operation, the compacting component 5a is installed on the connecting channel 4c, which can ensure that the loose food first passes through the preliminary drying and water removal process of the first drying chamber 4a to reduce the water content in the loose food. At this time, it is compacted, and then the compacted food is dried again in the second drying chamber 4b. While further realizing the water removal function, the firmness of the formed food can be improved, the possibility of the formed food loosening during the subsequent transmission process can be prevented, and the stability of transportation performance can be improved.

[0051] It is worth mentioning that when the compacting component 5a is compacting the food, the conveyor belt 2 is paused. At this time, the food in the first drying chamber 4a is subjected to a preliminary drying duration increase, the food in the connecting channel 4c is subjected to a compacting operation, and the food formed blocks in the second drying chamber 4b are subjected to secondary drying and plasticization.

[0052] Further, such as Figure 12-13As shown: the conflict bearing assembly 5b includes a fourth mounting frame 5b1, a second linear drive 5b2, a conflict bearing plate 5b3 and a transmission rod 5b4, the fourth mounting frame 5b1 is mounted on the frame 1, the fourth mounting frame 5b1 is located between the first drying chamber 4a and the second drying chamber 4b, two second linear drives 5b2 are provided, and the two second linear drives 5b2 are respectively vertically fixedly installed on the side walls on both sides of the fourth mounting frame 5b1, the conflict bearing plate 5b3 is horizontally arranged in the conveyor belt 2, and the conflict bearing plate 5b3 is located directly below the pressure plate 5a2, two transmission rods 5b4 are provided, the transmission rods 5b4 are horizontally arranged, and the two transmission rods 5b4 are respectively located on both sides of the conveyor belt 2, one end of the transmission rod 5b4 is fixedly connected to one end of the conflict bearing plate 5b3, and the other end of the transmission rod 5b4 is fixedly connected to the output end of one of the second linear drives 5b2.

[0053] The compaction assembly 5a is installed as a whole in the conveyor belt 2 through the first linear drive 5a1, and the two pressure plates 5a2 are output synchronously, which drives the transmission rod 5b4 to rise, and drives the rectangular forming groove 5a3 fixedly connected thereto to rise synchronously until the top of the rectangular forming groove 5a3 touches the conveyor belt 2, ensuring that when the compaction operation of the conveyor belt 2 is in progress, the upper belt of the conveyor belt 2 will not be deformed due to the downward pressure, thereby improving the forming effect.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
