Description

Technical Field

[0001] This invention relates to the field of food transportation equipment technology, and in particular to a conveying device for packaging, filtering oil, and removing residue from twisted dough sticks. Background Technology

[0002] In the production process of twisted dough sticks, the shaped dough needs to be deep-fried. After the deep-frying process is completed, the twisted dough sticks are transported by a conveyor device for subsequent packaging. However, when the existing conveyor device is transporting twisted dough sticks, a large amount of oil and residue remain on the surface of the freshly fried twisted dough sticks, resulting in a large amount of oil residue on the conveyor device during the transportation process, causing pollution of the conveyor device. If it is not cleaned in time, it can easily cause food safety hazards. Therefore, it is necessary to propose a twisted dough stick packaging, oil filtering and residue removal conveyor device.

[0003] For example, CN202310197338.X proposes a high-efficiency oil filtration system and method for frying donuts, including a frame, an oil drain tank, an oil discharge pipe above the oil drain tank, and a filter screen between the oil drain tank and the oil discharge pipe; characterized in that it further includes: a mesh conveying assembly, which is installed on the frame to intermittently convey the filter screen toward both sides of the oil drain tank; a mesh cleaning and filtration assembly, which is installed on both sides of the oil discharge pipe to collect, squeeze out, and discharge the filter residue on the filter screen arranged in a "V" shape; and a mesh discharge assembly, which is located on one side of the mesh cleaning and filtration assembly to push out oil by folding the filter screen. This invention has the advantages of good filtration effect of edible oil after frying and can realize rapid discharge of filter screen and filter residue, but it fails to solve the above-mentioned problems.

[0004] This invention effectively solves the problems of oil residue on the surface of twisted dough sticks and contamination of the conveying device through the synergistic effect of the oil filtration device, the slag removal device and the progressive device, and finally realizes the oil filtration and slag removal and orderly conveying of twisted dough sticks, ensuring food hygiene and safety and improving production efficiency.

[0007] Furthermore, the conveyor belt assembly is formed by hinged multiple placement plates; the placement plates are provided with a downward first protrusion and a second protrusion, and the placement plates are also provided with a vibrating plate and filter holes, with the second protrusion located on the vibrating plate and behind the first protrusion.

[0008] Furthermore, the vibration assembly includes a mounting plate and a collision ball; the mounting plate is fixed to the support frame and has multiple through holes; the collision ball is fixed to the mounting plate by a first spring, the collision ball is in contact with the placement plate, and the position of the collision ball corresponds to the position of the first protrusion.

[0009] Furthermore, the discharge assembly includes a hopper and a slag discharge belt assembly; the hopper is fixed on the support frame and is inclined to fit the conveyor belt assembly; the slag discharge belt assembly is located at the discharge end of the hopper, and a second motor is fixed on the side of the support frame, with the output shaft of the second motor being poweredly connected to the slag discharge belt assembly.

[0010] Furthermore, a movable plate is slidably provided at the upper end of the hopper, and a groove adapted to the movable plate is provided on the hopper; a second spring is provided between the movable plate and the hopper, and a brush is fixed on the movable plate, the brush being in contact with the lower end of the conveyor belt assembly.

[0011] Furthermore, the upper end of the slag discharge belt assembly is inclined, and both the upper and lower sides of the belt of the slag discharge belt assembly have brush structures.

[0012] Furthermore, the air outlet pipes are arranged in an "S" shape above the inclined front end of the conveyor belt assembly.

[0013] Furthermore, the first protrusion is a right-angled triangle structure, and the second protrusion is an arched structure.

[0014] Furthermore, the vibrating plate is provided with fixing claws for fixing the twisted rope.

[0015] Furthermore, both the sliding plate and the pusher plate are fixed with push blocks, which are arranged in a sawtooth pattern, and the push blocks on the sliding plate and the pusher plate are arranged alternately.

[0016] Beneficial effects The present invention has the following beneficial effects: (1) By setting up an oil filtration device, the present invention can efficiently filter the oil from freshly fried twisted dough sticks. The front end of the conveyor belt assembly is inclined, and combined with the airflow sprayed from the nozzles evenly distributed below the air outlet, it can quickly blow off the excess oil on the surface of the twisted dough sticks. At the same time, the collision ball in the vibration assembly contacts the first protrusion on the placement plate when the conveyor belt assembly is running, causing the placement plate to vibrate. Combined with the filter holes on the placement plate, it can further promote the dripping of oil from the twisted dough sticks. The dripping oil is collected by the hopper of the discharge assembly and then transported to the designated position by the slag discharge belt assembly, effectively reducing the oil residue on the device during the transportation process.

[0017] (2) The slag removal device can effectively remove the residue on the surface of the twisted dough sticks. The exhaust port is located above the funnel, which can blow the light residue on the surface of the twisted dough sticks into the funnel, realize the initial separation of the residue from the twisted dough sticks, avoid the residue from entering the subsequent packaging process with the twisted dough sticks, and ensure the product quality of the twisted dough sticks.

[0018] (3) The progressive device can push the twisted dough sticks in an orderly manner and remove slag again through the reciprocating motion of the pusher plate. The through holes on the sliding plate can allow the twisted dough sticks to drop fine residues to the slag discharge plate during the pushing process. The serrated pusher blocks arranged alternately on the sliding plate and the pusher plate can ensure that the twisted dough sticks are not easy to accumulate during the conveying process, and achieve stable and orderly conveying, which provides convenience for the subsequent packaging process.

[0019] (4) The conveyor belt assembly consists of multiple hinged placement plates. The vibrating plate and fixing claw on the placement plate can effectively fix the twisted dough, preventing it from shifting or falling during vibration oil filtration and conveying. At the same time, the cooperation between the vibration component and the first and second protrusions on the placement plate not only enhances the vibration effect but also facilitates the smooth operation of the placement plate.

[0020] (5) The moving plate and brush at the top of the hopper in the discharge assembly can clean the lower end of the conveyor belt assembly during operation, preventing grease and residue from sticking to the conveyor belt assembly, keeping the device clean and hygienic, and reducing food safety hazards. The brush structure on the upper and lower sides of the slag discharge belt assembly can also further clean the conveyed residue, ensuring the thoroughness of residue collection.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 - Figure 11 This invention provides a technical solution: a twisted dough stick packaging, oil filtering, and slag removal conveying device includes a support frame 1, which is installed behind an external twisted dough stick frying device. It also includes: an oil filtering device located at the front end of the support frame 1 for conveying and separating the twisted dough sticks and oil; a slag removal device located in the middle of the support frame 1 for separating the twisted dough sticks and residue; and a progressive device located at the rear end of the support frame 1 for conveying and further separating the twisted dough sticks and residue.

[0026] like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the twisted dough stick packaging, filtration, and slag removal conveying device includes an oil filtration device, which comprises rollers 2, a conveyor belt assembly 3, and a first motor 307. The rollers 2 are rotatably mounted on a support frame 1. The first motor 307 is fixed to one side of the support frame 1, and its output shaft is poweredly connected to the rollers 2. The conveyor belt assembly 3 is mounted on the rollers 2, and its front end is inclined. An air outlet pipe 17 is located above the inclined front end of the conveyor belt assembly 3. One end of the air outlet pipe 17 is connected to an external air pump to provide high-speed airflow. Evenly distributed nozzles are located below the air outlet pipe 17. The air outlet pipes 17 are arranged in an "S" shape. A vibration component 4 is provided inside the conveyor belt assembly 3. The vibration component 4 is located on the inner front end and inner lower end of the conveyor belt assembly 3. The conveyor belt assembly 3 is formed by hinged connections of multiple placement plates 301. Each placement plate 301 has a downward-facing first protrusion 302 and a second protrusion 304. A vibration plate 303 is provided on the placement plate 301. Filter holes 305 are provided on the placement plate 301. The second protrusion 304 is located on the vibration plate 303 and behind the first protrusion 302. The first protrusion 302 is a right-angled triangle. The second protrusion 304 is arched. The vibration assembly 4 consists of a mounting plate 401 and a collision ball 402. The mounting plate 401 has multiple through holes. The collision ball 402 is fixed to the mounting plate 401 by a first spring 403. The collision ball 402 contacts the placement plate 301. The position of the collision ball 402 corresponds to the first protrusion 302. A discharge assembly 5 is provided below the conveyor belt assembly 3. The discharge assembly 5 consists of a hopper 501 and a slag discharge belt assembly 506. The hopper 501 is fixed to the support frame 1. The hopper 501 is inclined to fit the conveyor belt assembly 3. A movable plate 502 is slidably provided at the upper end of 501. The hopper 501 is provided with a groove that fits the movable plate 502. A second spring 503 is provided between the movable plate 502 and the hopper 501. A brush 504 is provided on the movable plate 502. The brush 504 contacts the lower end of the transmission belt assembly. The upper end of the slag discharge belt assembly 506 is inclined. The hopper 501 is provided with a discharge port corresponding to the slag discharge belt assembly 506 for discharging the generated waste slag. A second motor 505 is provided on the side of the support plate for driving the slag discharge belt assembly 506. The belt on the slag discharge belt assembly 506 has a brush structure on both the upper and lower sides.

[0027] In a specific embodiment: during use, the fried dough twists will contact the inclined front end of the conveyor belt assembly 3. At the same time, the first motor 307 is started and rotated by an external power source, driving the roller 2 to rotate, thereby causing the conveyor belt assembly 3 to rotate, which in turn drives the dough twists in contact with the conveyor belt assembly 3 to move, thereby causing the dough twists to detach from the external frying device. At the same time, a high-speed airflow is sprayed out from the air outlet pipe 17 to cool down the passing dough twists, preventing them from being over-fried and blowing away any residual oil. The high-speed airflow also makes the dough twists press down better on the conveyor belt assembly 3, thereby ensuring the stability of the dough twists' movement.

[0028] Simultaneously, as the conveyor belt assembly 3 rotates, the first protrusion 302 on the control plate pushes the collision ball 402 and causes the first spring 403 to deform. When the collision ball 402 passes the first protrusion 302, the spring's deformation resets, causing the collision ball 402 to strike the second protrusion 304 at high speed. This causes the vibrating plate 303 on the placement plate 301 to vibrate, allowing the grease remaining on the conveyor belt assembly 3 to quickly detach. The high-frequency vibration also helps the grease on the twist to detach from the twist faster. The detached grease falls into the hopper 501 through the gaps between the placement plates 301 and the filter holes 305 on the placement plate 301. It is then naturally pushed down by the inclined hopper 501 and discharged from the side of the hopper 501 under the pushing and guiding action of the slag discharge belt assembly 506.

[0029] Meanwhile, the elastic force of the second spring 503 causes the brush 504 on the moving plate 502 to continuously clean the bottom of the conveyor belt assembly 3, ensuring the long-term use of the conveyor belt assembly 3. Moreover, the upper and lower brush structure of the belt in the slag discharge belt assembly 506 allows the grease on the falling bucket to pass through the brush structure and return to the external frying device along the lower funnel 8, while the falling residue is intercepted by the brush structure and swept to one side of the falling bucket for discharge.

[0030] In a more preferred embodiment: such as Figure 6 As shown, the vibrating plate 303 is provided with a fixing claw 306 to facilitate fixing the twisted rope.

[0031] like Figure 3 and Figure 9 As shown, the twisted dough stick packaging, filtration, and slag removal conveying device includes a slag removal device, which includes an exhaust port 7 and a funnel 8. The exhaust port 7 and the funnel 8 are fixed to the middle of the support frame 1, and the exhaust port 7 is located above the funnel 8.

[0032] In a specific embodiment: the exhaust port 7 generates a high-speed airflow through an external air pump, thereby forming an air wall, which separates the twisted dough sticks and residues thrown out by the oil filter device. The residues are small in mass and will be blown into the funnel 8 by the airflow, while the large twisted dough sticks are less affected by the airflow, thus separating the twisted dough sticks and residues.

[0033] like Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, the twisted dough stick packaging, filtration, and slag removal conveying device includes a progressive device, which comprises a guide plate 9, a sliding plate 10, a slag discharge plate 11, a pusher plate 12, and a third motor 16. The guide plate 9 is fixed to the support frame 1 and located behind the funnel 8. The sliding plate 10 is fixed to the support frame 1 and located behind the guide plate 9. The sliding plate 10 has evenly distributed through holes. The slag discharge plate 11 is inclinedly fixed to the support frame 1 and located below the sliding plate 10. The pusher plate 12... The material plate 12 is slidably mounted above the sliding plate 10. The third motor 16 is fixed to the side of the support frame 1. The output shaft of the third motor 16 is equipped with a crankshaft 14. The crankshaft 14 is poweredly connected to the push plate 12 through a hinged connecting plate 15, so that the push plate 12 can reciprocate. Pushing blocks 13 are fixed on the sliding plate 10 and the push plate 12. The pushing blocks 13 are arranged in a sawtooth pattern and are staggered on the sliding plate 10 and the push plate 12.

[0034] In a specific embodiment: during use, the twisted dough falls onto the guide plate 9 and then slides onto the sliding plate 10. The third motor 16 is started and rotated by an external power source, thereby driving the crankshaft 14 to rotate. This drives the pusher plate 12 to reciprocate through the connecting plate 15, thus gradually pushing the twisted dough backward to achieve the purpose of conveying the twisted dough. At the same time, during the gradual movement, the twisted dough is continuously shaken to further shake off and remove residue from the twisted dough.

[0035] Working principle: When the fried dough twists are conveyed to the inclined front end of the conveyor belt assembly 3 via an external device, the first motor 307 drives the roller 2 to rotate, which in turn drives the conveyor belt assembly 3 to receive and transport the dough twists. During this process, the air pump connected to the air outlet 17 generates a high-speed airflow, which cools the dough twists through the "S"-shaped nozzles, blows away residual grease from the surface, and causes the dough twists to be stably pressed down on the conveyor belt assembly 3. As the conveyor belt assembly 3 continues to operate, the first protrusion 302 on the placement plate 301 pushes the collision ball 402 of the vibration assembly 4, causing the first spring 403 to deform. When the collision ball 402 passes the first protrusion 302, the spring returns to its original position, causing the collision ball 402 to strike the second protrusion 304 on the vibration plate 303 at high speed, triggering the high-frequency vibration of the vibration plate 303, accelerating the removal of grease from the dough twists and the conveyor belt assembly 3. The detached grease falls through the gaps in the placement plate 301 and the filter holes 305 to the lower part of the conveyor belt assembly 3. The material is discharged from the hopper 501 and then guided by the slag discharge belt assembly 506. At the same time, the moving plate 502 under the action of the second spring 503 drives the brush 504 to continuously clean the lower end of the conveyor belt assembly 3. The brush structure of the slag discharge belt assembly 506 realizes the separation of oil and residue. The oil flows back to the external frying device, and the residue is intercepted and discharged. The oil-filtered twists are conveyed by the conveyor belt assembly 3 into the slag removal device area. The exhaust port 7 is connected to an external air pump to form a high-speed air wall, which blows the smaller residue into the funnel 8 for separation. The larger twists fall to the guide plate 9 and slide towards the sliding plate 10 of the progressive device. Then, the third motor 16 drives the crankshaft 14 to rotate, which drives the pusher plate 12 to reciprocate on the sliding plate 10 through the connecting plate 15. The twists are progressively conveyed by the staggered sawtooth pusher block 13. During the conveying process, the residue is further removed by shaking, and finally the oil filtering, slag removal and stable conveying of the twists are realized.
