Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to a dairy conveying device with a sterilization function and a use method thereof. Background Art

[0002] Dairy products contain a large number of trace elements that are beneficial to the human body and are deeply loved by the general public. In order to ensure the quality of dairy products after packaging, the dairy bottles need to be sterilized before packaging, and the produced dairy products are filled in the bottles. During the transportation of dairy bottles, a conveying device is required. Generally, a conveyor belt is used to complete the conveying work. The conveyor belt is a rubber, fiber, or metal composite product used in a belt conveyor belt to carry and transport materials, or a plastic and fabric composite product.

[0003] For example, a non-slip conveying device for milk bottle conveying with announcement number CN213036734U includes a base, a mounting plate is arranged on the top of the base, a guide groove is provided in the vertical direction, an L-shaped folding plate is inserted inside the guide groove, a bracket is arranged on the top of the L-shaped folding plate, and a driving roller and a driven roller are arranged on the sides of the two brackets respectively, and the driving roller and the driven roller are connected by a conveyor belt transmission, a motor is arranged on the top of the left bracket, and the output shaft of the motor is connected to the driving roller by a belt transmission, a limiting block is arranged on the surface of the conveyor belt, and an anti-sliding block is arranged on the side of the limiting block. The structural design of the utility model is scientific and reasonable. By setting the limiting block and the anti-sliding block, the problem of milk bottles easily sliding during transportation is solved.

[0004] As food, dairy products should be produced and transported in a sterile environment. Traditional dairy packaging bottles are equidistantly distributed on the conveyor belt. During the transportation process, there is no protective mechanism on the periphery of the dairy packaging bottles. The dairy packaging bottles are easily adhered to bacteria in the air and are prone to fall. If a protective mechanism is installed on the periphery of the dairy packaging bottles, the periphery of the packaging bottle will be in contact with the protective mechanism for too long, and it is difficult to ensure that the protective mechanism is in a sterile state, affecting the quality of the dairy products. Therefore, we propose a dairy conveying device with a sterilization function and a method of use thereof to solve the above-mentioned problems. Summary of the invention

[0018] The present invention also discloses a method for using a dairy product conveying device with a sterilization function, comprising the following steps:

[0019] S1: Turn on the ultraviolet lamp, which irradiates the inside of the outer protective part and the inner protective part for sterilization;

[0020] S2: The dairy products are filled into packaging bottles, and the packaging bottles containing the dairy products are placed on the conveyor belt one by one using a robotic arm;

[0021] S3: After the conveyor belt is turned on, the packaging bottles containing dairy products are transported by the conveyor belt, and the ultraviolet lamp irradiates and sterilizes the packaging bottles containing dairy products;

[0022] S4: A rack plate is installed at the starting point of the conveyor belt. When the sleeve of the connecting mechanism moves to the position of the rack plate, the pulling hook of the pulling mechanism opens the outer guard and the inner guard, increasing the relative distance between the two protection mechanisms. The operator places the packaging bottle of dairy products in the gap between the two protection mechanisms.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. An ultraviolet lamp is arranged between the outer protective part and the inner protective part. The ultraviolet lamp is on for a long time and can irradiate and sterilize the internal space of the outer protective part and the inner protective part in real time. The outer protective part and the inner protective part can be opened to facilitate the placement of dairy products. At the same time, the angle between the first pulling plate and the second pulling plate can be enlarged to facilitate the expansion of the opening and closing range, so as to stretch the wrapping part, further increasing the convenience of placing dairy products. The outer protective part and the inner protective part are relaxed, and the outer protective part, the inner protective part and the wrapping part wrap the dairy products inside them, which is convenient for stable transportation.

[0027] 2. When the operator places the dairy product packaging in this space, the four rotating wheels of the first pulling plate and the second pulling plate all hit the outer circumference of the dairy product outer packaging. The rotating wheels are spread out along the round packaging bottle and clamped on the outer circumference of the packaging bottle, which not only fixes the dairy product packaging bottle, but also allows the ultraviolet lamp and the avoidance hole to directly irradiate the packaging bottle, thereby increasing the sterilization range.

[0028] 3. When the sleeve of the connecting mechanism moves to the position of the rack plate, the sleeve moves toward the limit plate, and the pulling hook of the pulling mechanism can automatically trigger the outer guard and the inner guard to be pulled apart.

[0029] 4. When the sleeve of the connecting mechanism moves to the position of the rack plate, the elastic member expands and contracts adaptively. When the sleeve slides over the rack plate, the elastic member drives the protective mechanism, the pulling mechanism and the connecting mechanism to reset, which is convenient for wrapping the dairy package and facilitating transportation and sterilization.

DETAILED DESCRIPTION

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

[0041] Example 1: Please refer to Figure 1-Figure 6 A dairy conveying device with a sterilization function includes a conveying mechanism 1, which includes a mounting frame 11 and a conveyor belt 12 rotatably arranged on the upper end of the mounting frame 11. The conveyor belt 12 is installed on the mounting frame 11. The conveyor belt 12 includes a belt and two transmission wheels. The two ends of the belt are respectively rotatably installed on the transmission wheels. One end of the transmission wheel is connected to a motor. After the motor is turned on, the belt rotates, and the conveyor belt 12 can work. The dairy packaging bottles are placed on the conveyor belt 12 in sequence, and the conveyor belt 12 drives them to be transported.

[0042] A protective mechanism 2 is provided at the upper end of the conveying mechanism 1, and the protective mechanism 2 includes an outer protective member 21 and an inner protective member 22 arranged inside the outer protective member 21, and a first fixing member 23 and a second fixing member 24 are fixedly installed between the outer protective member 21 and the inner protective member 22, and a through hole 25 is opened on the first fixing member 23 and the second fixing member 24. A wrapping member 26 is also fixedly installed on one side of the outer periphery of the outer protective member 21, and an ultraviolet lamp 6 is provided between the outer protective member 21 and the inner protective member 22. The ultraviolet lamp 6 is in a long-term lighting state, and can irradiate and sterilize the internal space of the outer protective member 21 and the inner protective member 22 in real time.

[0043] A pulling mechanism 3 is provided on one side of the protective mechanism 2, and the pulling mechanism 3 includes a connecting member 31, and a first pulling plate 32 and a second pulling plate 33 are rotatably installed on one side of the connecting member 31, and one end of the first pulling plate 32 and the second pulling plate 33 are fixedly installed with a pulling hook 34, and the four pulling hooks 34 are respectively clamped on the outer guard 21 and the inner guard 22, and the connecting member 31 is located inside the outer guard 21 and the inner guard 22.

[0044] There are two protective mechanisms 2, which are respectively arranged on both sides of the conveyor belt 12. The outer protective member 21 and the inner protective member 22 are connected together by the first fixing member 23 and the second fixing member 24 to ensure the stability of both. The inner protective member 22 is also fixedly installed on both sides of the upper end of the conveyor belt 12.

[0045] The first pulling plate 32 and the second pulling plate 33 can pull the outer protective member 21 and the inner protective member 22 apart through the pulling hook 34, thereby increasing the distance between the two relative protective mechanisms 2, making it easier to place the dairy products therein; at the same time, the angle between the first pulling plate 32 and the second pulling plate 33 can be enlarged, thereby making it easier to expand the opening and closing range, thereby enabling the wrapping member 26 to be opened, further increasing the convenience of placing the dairy products, and loosening the outer protective member 21 and the inner protective member 22, so that the outer protective member 21, the inner protective member 22 and the wrapping member 26 wrap the dairy products therein.

[0046] During the process of conveying the dairy packaging bottles driven by the conveyor belt 12, the outer protective member 21 and the inner protective member 22 are respectively arranged on both sides of the dairy packaging bottles to ensure the stability of the dairy packaging bottles. The wrapping member 26 is a trumpet-shaped structure. During the conveying process of the dairy packaging bottles, the wrapping member 26 can completely wrap them, and in combination with the irradiation of the ultraviolet lamp 6, the periphery of the dairy packaging bottles can be sterilized.

[0047] The outer protective part 21, the inner protective part 22 and the wrapping part 26 are all made of rubber material, which is convenient for adapting to the deformation of the conveyor belt 12 during rotation. The three are located on the periphery of the dairy packaging bottle. When they contact the packaging bottle, they can not only ensure the stability of the dairy packaging bottle, but also reduce the wear during contact. Under the long-term irradiation of the ultraviolet lamp 6, the connection is not easy to breed bacteria, ensuring that the dairy product has a sterilization function during the transportation process and ensuring the product quality.

[0048] Example 2: Please refer to Figure 2-Figure 6 Limiting plates 13 are fixedly mounted on the two inner walls of the mounting frame 11 . The two limiting plates 13 are respectively arranged on both sides of the conveyor belt 12 for limiting the protection mechanism 2 .

[0049] The first pulling plate 32 and the second pulling plate 33 are both U-shaped structures, which are convenient for clamping the outer protective part 21 and the inner protective part 22 at the same time. The pulling mechanism 3 is arranged between the outer protective part 21 and the inner protective part 22. The pulling mechanism 3 also includes a connecting column 35 fixedly installed at one end of the pulling hook 34, and a rotating wheel 36 is rotatably installed at one end of the connecting column 35. Connecting blocks 37 are fixedly installed on the inner walls of the first pulling plate 32 and the second pulling plate 33, and an avoidance hole 38 is opened in the middle of the connecting block 37, and the ultraviolet lamp 6 is adapted to the avoidance hole 38.

[0050] After the ultraviolet lamp 6 is turned on, the light source thereof shines on the outer packaging of the dairy product through the avoidance hole 38 , and sterilizes and disinfects the internal structure of the protection mechanism 2 .

[0051] When the outer protective member 21 and the inner protective member 22 are opened, the first pulling plate 32 and the second pulling plate 33 are merged together, freeing up a certain space relative to the two protective mechanisms 2. When the operator places the dairy product package in this space, the four rotating wheels 36 of the first pulling plate 32 and the second pulling plate 33 all contact the outer periphery of the dairy product outer package. After the outer protective member 21 and the inner protective member 22 are merged, the rotating wheels 36 are unfolded along the circular packaging bottle and clamped on the outer periphery of the packaging bottle, which not only fixes the dairy product packaging bottle, but also allows the ultraviolet lamp 6 and the avoidance hole 38 to directly irradiate the packaging bottle, thereby increasing the sterilization range.

[0052] Example 3: Please refer to Figure 2-Figure 9 A rack plate 14 is fixedly mounted on the inner walls at both ends of the limit plate 13, a connecting mechanism 4 is provided at one end of the pulling mechanism 3, and the connecting mechanism 4 includes a sleeve 41 connected to the through hole 25, and a gear 42 meshing with the rack plate 14 is rotatably mounted on one end of the sleeve 41, and a sliding block 44 is fixedly mounted on the inner wall of the gear 42.

[0053] A fixing mechanism 5 is arranged inside the connecting mechanism 4, and the fixing mechanism 5 includes a fixing block 51 fixedly mounted on the inner wall of the inner guard 22, an inner rod 52 is fixedly mounted on one end of the fixing block 51, the inner rod 52 is interlaced and connected with the sleeve 41, a threaded groove 53 is fixedly mounted on one end of the inner rod 52, and a sliding block 44 is slidably mounted on the threaded groove 53.

[0054] When the conveyor belt 12 rotates, the protection mechanism 2, the pulling mechanism 3 and the connecting mechanism 4 rotate together. When the sleeve 41 of the connecting mechanism 4 moves to the position of the rack plate 14, the gear 42 on one side of the sleeve 41 meshes with the rack plate 14 and rotates. During the rotation of the gear 42, the sliding block 44 on its inner wall cooperates with the threaded groove 53 of the inner rod 52 to drive the sleeve 41 to move toward the limit plate 13.

[0055] A connecting ear 43 is fixedly mounted on one end of the sleeve 41 away from the gear 42 , a first connecting rod 45 is rotatably mounted on the connecting ear 43 , and one end of the first connecting rod 45 away from the connecting ear 43 is rotatably connected to the connecting block 37 .

[0056] The sleeve 41 is connected to the pulling mechanism 3 through the first connecting rod 45. When the sleeve 41 of the connecting mechanism 4 moves to the position of the rack plate 14, the sleeve 41 moves toward the limit plate 13, and the pulling hook 34 of the pulling mechanism 3 pulls the outer guard 21 and the inner guard 22 apart, increasing the relative distance between the two protective mechanisms 2 for the placement of dairy products. Therefore, when the conveyor belt 12 is transported to the position of the rack plate 14, the outer guard 21 and the inner guard 22 can be automatically triggered to be pulled apart.

[0057] Example 4: Please refer to Figure 2-Figure 9 A protrusion 54 is fixedly installed at one end of the inner rod 52, and the ultraviolet lamp 6 is fixedly installed at one end of the protrusion 54. Two second connecting rods 55 are rotatably installed at one end of the protrusion 54. The end of the second connecting rod 55 away from the protrusion 54 is rotatably connected to the middle part of the first connecting rod 45.

[0058] When the sleeve 41 of the connecting mechanism 4 moves to the position of the rack plate 14, the connecting mechanism 4 and the pulling mechanism 3 move as a whole toward the limit plate 13, while the position of the fixing mechanism 5 remains unchanged. Through the cooperation between the first connecting rod 45 and the second connecting rod 55, the two second connecting rods 55, the first pulling plate 32 and the second pulling plate 33 can be driven to open, thereby increasing the placement space of the outer guard 21 and the inner guard 22, and further increasing the convenience of placing the dairy packaging bottles.

[0059] A reset mechanism 7 is arranged on the periphery of the connecting mechanism 4. The reset mechanism 7 includes a fixing ring 71 fixedly mounted on the periphery of the sleeve 41. An elastic member 72 is fixedly mounted on one end of the fixing ring 71. The elastic member 72 is arranged on the periphery of the sleeve 41, and one end of the elastic member 72 is also fixedly connected to the first fixing member 23.

[0060] When the sleeve 41 of the connecting mechanism 4 moves to the position of the rack plate 14, the elastic member 72 adaptively expands and contracts. When the sleeve 41 slides over the rack plate 14, the elastic member 72 drives the protective mechanism 2, the pulling mechanism 3 and the connecting mechanism 4 to reset, so as to facilitate the wrapping of the dairy package, and facilitate the transportation and sterilization.

[0061] The present invention also discloses a method for using a dairy product conveying device with a sterilization function, comprising the following steps:

[0062] S1: Turn on the ultraviolet lamp 6, and the ultraviolet lamp 6 irradiates the inside of the outer protective part 21 and the inner protective part 22 for sterilization;

[0063] S2: The dairy product is filled into the packaging bottles, and the packaging bottles containing the dairy product are placed on the conveyor belt 12 in sequence by using a robotic arm;

[0064] S3: After the conveyor belt 12 is turned on, the packaging bottles containing the dairy products are transported by the conveyor belt 12, and the ultraviolet lamp 6 irradiates and sterilizes the packaging bottles containing the dairy products;

[0065] S4: A rack plate 14 is installed at the starting point of the conveyor belt 12. When the sleeve 41 of the connecting mechanism 4 moves to the position of the rack plate 14, the pulling hook 34 of the pulling mechanism 3 opens the outer guard 21 and the inner guard 22, thereby increasing the distance between the two relative guard mechanisms 2. The operator places the packaging bottle of the dairy product in the gap between the two guard mechanisms 2.

[0066] S5: When the sleeve 41 of the connecting mechanism 4 slides over the rack plate 14, the elastic member 72 drives the protective mechanism 2, the pulling mechanism 3 and the connecting mechanism 4 to reset, so as to wrap the dairy product package;

[0067] S6: A rack plate 14 is installed again at the end of the conveyor belt 12. When the conveyor belt 12 transports the packaging bottle containing the dairy product to the designated position, the outer guard 21 and the inner guard 22 are triggered to open again, and the packaging bottle can be taken out.
