Description

Technical Field

[0001] This utility model relates to the field of chili oil packaging technology, and in particular to a fully automatic packaging equipment for the production of chili oil for Lanzhou beef noodles. Background Technology

[0002] Lanzhou ramen, also known as Lanzhou beef ramen, is a traditional specialty food of Lanzhou, Gansu Province, China. It is famous for its unique taste and rich cultural connotation. The chili oil in Lanzhou ramen is an important part of its unique flavor. The production method is meticulous and requires careful blending. The chili oil production process requires the use of fully automated packaging equipment.

[0003] There are still some problems in the use of existing fully automatic packaging equipment for the production of chili oil for Lanzhou beef noodles. The packaging structure is not easy to adjust according to the size of the packaging, and the continuous conveying of chili oil during the production process is also not convenient for packaging. Therefore, those skilled in the art provide a fully automatic packaging equipment for the production of chili oil for Lanzhou beef noodles to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fully automatic packaging equipment for the production of chili oil for Lanzhou beef noodles. By rotating the up and down moving nut, the distance between the cold sealing device and the heat sealing structure can be adjusted up and down to facilitate sealing according to the actual situation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic packaging equipment for producing chili oil for Lanzhou beef noodles, comprising a main body and a control box, wherein the control box is located on one side of the main body, the upper surface of the main body is provided with a film-laying structure, a guide is provided at the upper center of the main body, a heat-sealing structure is provided inside the main body below the guide, and an adjustable cold-sealing structure is provided inside the main body below the heat-sealing structure.

[0006] The adjustable cold-sealing structure includes a frame. A vertically movable nut is fixedly connected to the center of one side wall of the frame. One end of the vertically movable nut passes through the side wall of the frame and extends to the other end of the frame. A first umbrella wheel is fixedly sleeved on the outer side wall of the vertically movable nut on one side of the frame. A second umbrella wheel is provided on the upper end of each of the two first umbrella wheels. A first lead screw is fixedly connected to the upper end of each of the two second umbrella wheels. A fixed seat is sleeved on both the upper and lower ends of each of the two first lead screws. A slider is threaded onto the outer side wall of each of the two first lead screws. A cold-sealing device is fixedly connected between the two sliders.

[0007] The above technical solution involves placing the film using a film-laying structure, guiding it through a guide, and then sealing both sides using a heat-sealing structure. Rotating the up-and-down moving nut causes the two first umbrella wheels to rotate, which in turn drives the two second umbrella wheels to rotate. This causes the two first lead screws to rotate through four fixed seats, allowing the two sliders to move up and down along the two first lead screws. This adjusts the distance between the slider and the heat-sealing structure, facilitating sealing according to actual conditions.

[0008] Furthermore, the adjustable cold sealing structure has a cutting device inside the lower end of the main body of the equipment. The cutting device includes a bracket, and a shaft is rotatably connected to the center of the front end face of the bracket on one side. A first sleeve and a second sleeve are arranged in a front-to-back arrangement on the outer side wall of the shaft at the front end of the bracket. Corrugated teeth are provided at the rear end of the first sleeve and the front end of the second sleeve. The rear end of the shaft passes through the bracket and extends into the inside of the bracket. A rotating blade is fixedly connected to one side wall of the shaft. A fixed blade is fixedly connected inside the bracket on one side of the rotating blade.

[0009] With the above technical solution, by pressing the first sleeve, the two corrugated teeth are made to fit together. Then, by rotating the first sleeve, the second sleeve is made to rotate with the first sleeve, thereby driving the rotating blade to rotate. The position that intersects with the fixed blade is cut along the opening position, which facilitates cutting.

[0010] Furthermore, a fine-tuning handle is rotatably connected to the upper center of one side wall of the bracket. The end of the fine-tuning handle passes through the side wall of the bracket and extends into the interior of the bracket. A helical gear is provided at the end of the handle. A handle is provided on the lower end face of the bracket below the fine-tuning handle.

[0011] The above technical solution facilitates fine-tuning by adjusting the connection between the helical gear and the shaft using a handle.

[0012] Furthermore, the upper end of the bracket is provided with a base plate, a cutting knife is rotatably connected to the center of the upper surface of the base plate, a guide block is fixedly connected to one rear side of the upper surface of the base plate, and a guide groove is opened on one side of the center of the front surface of the guide block.

[0013] The above technical solution involves rotating the cutting blade, which, after being guided by the guide groove, cuts an opening at the sealing position.

[0014] Furthermore, a feeding structure is provided on one side of the main body of the equipment. The feeding structure includes a material barrel. A feeding pipe is provided at the upper center of the rear end face of the material barrel. A material level observation window is provided at the lower side of one side of the front end face of the material barrel. A rotary valve body is fixedly connected to the lower end of the material level observation window. A material cylinder and a back suction cylinder are fixedly connected to the lower end and one side of the rotary valve body, respectively. A material injection nozzle is fixedly connected to the output end of the back suction cylinder.

[0015] The above technical solution involves storing chili oil in a hopper, observing the remaining amount of chili oil through a material level observation window, controlling the discharge through a rotary valve, and then discharging the chili oil through an injection nozzle.

[0016] Furthermore, a gearbox is provided at the lower end of the material cylinder and the return suction cylinder. A gear observation window is provided at the center of the front end face of the gearbox. A gear set is provided inside the gear observation window. A rotary valve connecting rod is fixedly connected to one side of the center of the upper end face of the gearbox. A clutch handle is provided on the front end face of the gearbox located on one side of the gear observation window.

[0017] The above technical solution uses a clutch lever to control power and start the gear set.

[0018] Furthermore, the gear set includes a driving gear, a first driven gear at the lower end of the driving gear, a second driven gear on one side of the first driven gear, a rotating rod fixedly connected to the center of the front end face of both the first driven gear and the second driven gear, and a first connecting rod and a second connecting rod rotatably connected to the other ends of the two rotating rods respectively, and a piston rotatably connected to the other ends of both the first connecting rod and the second connecting rod.

[0019] With the above technical solution, when the clutch lever is engaged, power is transmitted to the first driven gear through the driving gear, and then to the second driven gear through the first driven gear. The first and second driven gears drive the rotating rods to rotate, and the two rotating rods thereby cause the first and second connecting rods to rotate, so that the two pistons move up and down inside the material cylinder and the suction cylinder. The two pistons move up and down in opposite directions to draw in material, forming an output difference, thereby realizing the intermittent conveying of materials.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the fully automatic packaging equipment for Lanzhou beef noodle chili oil production uses a film-laying structure to lay the film. After being guided by a guide, the film is first sealed on both sides by a heat-sealing structure. Then, by rotating the up-and-down moving nut, the up-and-down moving nut drives the two first umbrella wheels to rotate, which in turn drives the two second umbrella wheels to rotate. This causes the two first lead screws to rotate through four fixed seats, thereby causing the two sliders to move up and down along the two first lead screws, thus adjusting the distance between them and the heat-sealing structure, making it easier to seal the product according to the actual situation.

[0022] 2. In this utility model, when the clutch lever is engaged, power is transmitted to the first driven gear through the driving gear, and then to the second driven gear through the first driven gear. The first driven gear and the second driven gear respectively drive the rotating rod to rotate. The two rotating rods thereby adjust the rotation of the first connecting rod and the second connecting rod, causing the two pistons to move up and down inside the material cylinder and the suction cylinder. The two pistons move up and down in opposite directions to draw in material, forming an output difference, thereby realizing intermittent material conveying.

[0023] 3. In this utility model, the cutting knife rotates and cuts the sealing position after being guided by the guide groove. After moving downward, the first sleeve is pressed to make the two corrugated teeth fit together. Then the first sleeve is rotated so that the second sleeve rotates with the first sleeve, thereby driving the rotating knife to rotate. The position where it intersects with the fixed knife is cut along the opening position, which facilitates cutting. Attached Figure Description

The film is released through the film release structure 4, guided by the guide 6, and then sealed on both sides by the heat sealing structure 7. Then, by rotating the up-and-down moving nut 302, the up-and-down moving nut 302 drives the two first umbrella wheels 303 to rotate, thereby driving the two second umbrella wheels 304 to rotate, causing the two first lead screws 306 to rotate through the four fixed seats 305, thereby causing the two sliders 307 to move up and down along the two first lead screws 306, thereby adjusting the distance between them and the heat sealing structure 7, so as to facilitate sealing according to the actual situation.

[0035] like Figure 5 As shown, the adjustable cold sealing structure 3 has a cutting device 2 inside the lower part of the main body 1. The cutting device 2 includes a bracket 201. A shaft 203 is rotatably connected to the center of the front end of the bracket 201. A first sleeve 204 and a second sleeve 205 are arranged in a front-to-back arrangement on the outer wall of the shaft 203 at the front end of the bracket 201.

A fixed blade 207 is fixedly connected inside the bracket 201 on one side of the rotating blade 206. By pressing the first sleeve 204, the two corrugated teeth 202 are made to fit together. Then, the first sleeve 204 is rotated, causing the second sleeve 205 to rotate with the first sleeve 204, thereby driving the rotating blade 206 to rotate. The blade 206 is cut along the opening at the position where it intersects with the fixed blade 207, which facilitates cutting.

[0036] A fine-tuning handle 209 is rotatably connected to the upper center of one side wall of the bracket 201.

A handle 208 is provided on the lower end surface of the bracket 201 below the fine-tuning handle 209, so that the helical gear 210 can be adjusted to connect with the shaft 203 for fine-tuning.

[0037] The bracket 201 has a base plate 211 at its upper end. A cutting knife 212 is rotatably connected to the center of the upper surface of the base plate 211. A guide block 213 is fixedly connected to one rear side of the upper surface of the base plate 211. A guide groove 214 is opened on one side of the center of the front surface of the guide block 213. As the cutting knife 212 rotates, it is guided by the guide groove 214 to cut an opening at the sealing position.

[0038] like Figure 2 , 3 As shown, a feeding structure 5 is provided on one side of the main body 1 of the equipment. The feeding structure 5 includes a material barrel 501. A feeding pipe 502 is provided at the upper center of the rear end face of the material barrel 501. A material level observation window 503 is provided at the lower side of one side of the front end face of the material barrel 501. A rotary valve body 504 is fixedly connected to the lower end of the material level observation window 503. A material cylinder 508 and a back suction cylinder 511 are fixedly connected to the lower end and one side of the rotary valve body 504, respectively. A feeding nozzle 512 is fixedly connected to the output end of the back suction cylinder 511. Chili oil is stored in the material barrel 501, and the remaining amount of chili oil is observed through the material level observation window 503. The discharge is controlled by the rotary valve body 504 and discharged through the feeding nozzle.

[0039] Gearbox 506 is provided at the lower end of material cylinder 508 and suction cylinder 511. Gear observation window 509 is provided at the center of the front end face of gearbox 506. Gear set 510 is provided inside gear observation window 509. Rotary valve connecting rod 505 is fixedly connected to one side of the center of upper end face of gearbox 506. Clutch handle 507 is provided on the front end face of gearbox 506 located on one side of gear observation window 509. Power is controlled by clutch handle 507 to start gear set 510.

[0040] like Figure 4 As shown, the gear set 510 includes a driving gear 5101, a first driven gear 5102 at the lower end of the driving gear 5101, and a second driven gear 5103 on one side of the first driven gear 5102. Rotating rods 5106 are fixedly connected to the center of the front end faces of both the first driven gear 5102 and the second driven gear 5103. A first connecting rod 5104 and a second connecting rod 5105 are rotatably connected to the other ends of the two rotating rods 5106, respectively. A piston 5107 is rotatably connected to the other ends of both the first connecting rod 5104 and the second connecting rod 5105. When the clutch lever 507 is engaged... Power is transmitted through the drive gear 5101 to the first driven gear 5102, and then through the first driven gear 5102 to the second driven gear 5103. The first driven gear 5102 and the second driven gear 5103 drive the rotating rod 5106 to rotate. The two rotating rods 5106 thereby cause the first connecting rod 5104 and the second connecting rod 5105 to rotate, causing the two pistons 5107 to move up and down inside the material cylinder 508 and the return suction cylinder 511. The two pistons 5107 move up and down in opposite directions to draw in material, forming an output difference, thereby realizing intermittent material conveying.

[0041] Working principle: During use, the film is placed through the film-laying structure 4, guided by the guide 6, and then sealed on both sides by the heat-sealing structure 7. Then, by rotating the up-and-down moving nut 302, the up-and-down moving nut 302 drives the two first umbrella wheels 303 to rotate, thereby driving the two second umbrella wheels 304 to rotate, causing the two first lead screws 306 to rotate through the four fixed seats 305, thereby causing the two sliders 307 to move up and down along the two first lead screws 306, thereby adjusting the distance between them and the heat-sealing structure 7, so as to facilitate sealing according to the actual situation.

[0042] When the clutch lever 507 is engaged, power is transmitted through the drive gear 5101 to the first driven gear 5102, and then through the first driven gear 5102 to the second driven gear 5103. The first driven gear 5102 and the second driven gear 5103 respectively drive the rotating rod 5106 to rotate. The two rotating rods 5106 thereby cause the first connecting rod 5104 and the second connecting rod 5105 to rotate, causing the two pistons 5107 to move up and down inside the material cylinder 508 and the suction cylinder 511. The piston 5107 inside the material cylinder 508 moves downward, creating a negative pressure inside the material cylinder 508, drawing chili oil into the material barrel 501. The feed inlet of the guide 6 closes and the outlet opens. When the rotation continues, the two pistons 5107 move in opposite directions, the feed inlet closes and the outlet opens, the piston 5107 moves upward, and the chili oil is discharged.

[0043] When the piston 5107 inside the back suction cylinder 511 moves downward, it pushes the valve core of the rotary valve body 504 to rotate, thus switching the inlet and outlet of the material cylinder 508 and drawing chili oil into the back suction cylinder 511, thereby achieving intermittent material conveying.

[0044] Then, by rotating the cutting blade 212, the cutting blade 212 is guided by the guide groove 214 to cut the sealing position. After moving downward, the first sleeve 204 is pressed to make the two corrugated teeth 202 fit together. Then the first sleeve 204 is rotated to make the second sleeve 205 rotate with the first sleeve 204, thereby driving the rotating blade 206 to rotate. The blade 206 cuts along the opening position at the position that intersects with the fixed blade 207, which facilitates cutting.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
