Description

Technical Field

[0001] This application relates to the technical field of baking tunnel ovens, and more particularly to a baking tunnel oven that is easy to clean. Background Technology

[0002] A baking tunnel oven is a highly efficient continuous baking equipment widely used in the food baking industry. Its core structure resembles a long "tunnel," equipped with a heating system and a conveying system. During operation, the food ingredients to be baked are placed on a conveyor belt. As the conveyor belt moves slowly, the food enters the tunnel oven one by one. Under the set temperature and time conditions, the food is evenly heated through various means such as heat radiation, heat convection, and heat conduction to complete the baking process. Due to the continuous feeding and discharging characteristics of the tunnel oven, it can realize large-scale, batch food production, greatly improving baking efficiency. It is very suitable for baking various foods such as bread, cakes, biscuits, pizzas, meat products, and nuts. In modern food processing enterprises, the baking tunnel oven has become one of the indispensable key pieces of equipment.

[0003] Traditional baking tunnel ovens accumulate a lot of dust and impurities on their inner walls after prolonged use, requiring cleaning. However, cleaning from the inside is inconvenient, increasing the difficulty for workers and thus posing certain drawbacks. Therefore, to solve the above problems, this application provides a baking tunnel oven that is easy to clean. Utility Model Content

[0004] The purpose of this invention is to provide a baking tunnel oven that is easy to clean, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a baking tunnel oven that is easy to clean, comprising a base, a conveyor belt mounted on the top of the base, an adjusting plate mounted on the outer end of the base, a baking tunnel oven mounted on the top of the base and on the conveyor belt, a fixed frame mounted on the baking tunnel oven, a servo motor mounted on the inner end of the fixed frame, a first threaded rod mounted on the output shaft of the servo motor, a movable block mounted on the outer ring surface of the first threaded rod, and a movable scraper mounted on the bottom of the movable block.

[0006] Preferably, the fixed frame is connected to the baking tunnel oven, the outer ring surface of the first threaded rod is threadedly connected to the interior of the movable block, and the outer side surface of the movable block is slidably connected to the interior of the fixed frame.

[0007] Preferably, the inner wall of the baking tunnel oven is slidably connected to and tightly fitted with the movable scraper.

[0008] Preferably, the top of the baking tunnel oven has four sets of through holes at equal intervals, and a dust suction head is installed on the top of the baking tunnel oven and on the through holes. A vacuum cleaner is installed on the top of the fixed frame, and the vacuum cleaner is connected to the dust suction head through a connecting pipe.

[0009] Preferably, the top of the adjusting plate is rotatably connected to one end of the base, a fixing plate is installed on one end of the outer side of the base, an arc-shaped groove is opened on the outer side of the fixing plate, and a second threaded rod is installed on the outside of the adjusting plate and inside the arc-shaped groove.

[0010] Preferably, when the adjusting plate rotates, it synchronously drives the second threaded rod to slide inside the arc-shaped groove, and a nut is installed on the outer ring surface of the second threaded rod in close contact with the fixing plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] This easy-to-clean baking tunnel oven features a movable scraper that removes dust and impurities from the inner wall of the oven when the movable block moves, ensuring cleanliness inside. A vacuum cleaner transmits the cleaning power through a connecting pipe to a suction head, which removes dust stirred up during cleaning, further improving the cleaning effect. After the adjusting plate rotates and the second threaded rod slides into the arc groove to the appropriate position, the nut on the outer ring of the second threaded rod is tightened to ensure it is in close contact with the fixing plate. The nut and the fixing plate generate friction to fix the adjusting plate in the current position, ensuring stability after the angle is adjusted. This allows the adjusting plate to accurately catch the dust and impurities scraped from the conveyor belt and guide them to slide into the external collection box. The design is convenient to operate and highly practical. Attached Figure Description

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] A baking tunnel oven that is easy to clean, see reference Figure 1 - Figure 4 The system includes a base 1, a conveyor belt 2 mounted on the top of the base 1, an adjusting plate 3 mounted on the outer end of the base 1, a baking tunnel oven 4 mounted on the top of the base 1 and on the conveyor belt 2, a fixed frame 5 mounted on the baking tunnel oven 4, a servo motor 6 mounted on the inner end of the fixed frame 5, a first threaded rod 7 mounted on the output shaft of the servo motor 6, a movable block 8 mounted on the outer ring surface of the first threaded rod 7, and a movable scraper 9 mounted on the bottom of the movable block 8.

[0020] Reference Figure 1 - Figure 3 The fixed frame 5 is connected to the baking tunnel oven 4. The outer ring surface of the first threaded rod 7 is threadedly connected to the inside of the movable block 8. The outer side of the movable block 8 is slidably connected to the inside of the fixed frame 5. The connection between the fixed frame 5 and the baking tunnel oven 4 provides space for the movable block 8 and the movable scraper 9 to move smoothly into the baking tunnel oven 4 for cleaning. When the first threaded rod 7 is driven to rotate by the servo motor 6, the movable block 8 can only move in a straight line along the first threaded rod 7, thereby driving the movable scraper 9 to thoroughly clean the inner wall of the baking tunnel oven 4. The inner wall of the baking tunnel oven 4 and the movable scraper 9 are slidably connected and tightly fitted. The slidable connection and tight fit between the movable scraper 9 and the inner wall of the baking tunnel oven 4 allow the movable scraper 9 to fully contact the inner wall of the baking tunnel oven 4 during movement. When the movable block 8 drives the movable scraper 9 to move, it scrapes off the dust and impurities on the inner wall, ensuring the cleanliness of the inside of the baking tunnel oven 4.

[0021] Reference Figure 1 - Figure 3The top of the baking tunnel oven 4 has four sets of through holes 10 at equal intervals. A dust suction head 11 is installed on the top of the baking tunnel oven 4 and on the through holes 10. A vacuum cleaner 12 is installed on the top of the fixed frame 5. The vacuum cleaner 12 is connected to the dust suction head 11 through a connecting pipe 13. When the vacuum cleaner 12 is started, the dust is transmitted to the dust suction head 11 through the connecting pipe 13. The dust suction head 11 can suck up the dust raised during the cleaning of the interior of the baking tunnel oven 4 through the through holes 10, further improving the cleaning effect.

[0022] Reference Figure 1 - Figure 4 The top of the adjusting plate 3 is rotatably connected to one end of the base 1. A fixing plate 14 is installed on one end of the outer side of the base 1. An arc-shaped groove 15 is formed on the outer side of the fixing plate 14. A second threaded rod 16 is installed on the outside of the adjusting plate 3 and inside the arc-shaped groove 15. When it is necessary to collect dust and impurities scraped off the conveyor belt 2, the adjusting plate 3 is rotated. Since the top of the adjusting plate 3 is rotatably connected to one end of the base 1, the adjusting plate 3 can rotate around the rotation point. During the rotation, the second threaded rod 16 on the outside of the adjusting plate 3 slides in the arc-shaped groove 15 on the outer side of the fixing plate 14. The arc-shaped groove 15 limits the rotation range of the adjusting plate 3 and ensures the stability of the adjustment process. By adjusting the angle of the adjusting plate 3, This allows it to accurately catch dust and impurities scraped off the conveyor belt 2 and guide them to slide into the external collection box for easy subsequent processing. When the adjusting plate 3 rotates, it simultaneously drives the second threaded rod 16 to slide inside the arc groove 15. The outer ring surface of the second threaded rod 16 is fitted with a nut 17 that is in close contact with the fixing plate 14. After the adjusting plate 3 rotates and drives the second threaded rod 16 to slide into the arc groove 15 to a suitable position, the nut 17 that is in close contact with the fixing plate 14 is tightened. The nut 17 and the fixing plate 14 are in close contact, generating friction to fix the adjusting plate 3 in the current position, ensuring that the adjusting plate 3 remains stable after the angle is adjusted and will not be displaced due to external forces or vibrations during equipment operation.

[0023] The implementation principle of a baking tunnel oven that is easy to clean according to an embodiment of this application is as follows: During use, the servo motor 6 and the vacuum cleaner 12 are electrically connected to an external power source via a switch. The fixed frame 5, connected to the baking tunnel oven 4, provides movement space for the movable block 8 and the movable scraper 9, allowing them to smoothly enter the interior of the baking tunnel oven 4 for cleaning. The servo motor 6... Preferably, the HBS57 type is used. When the servo motor 6 is started by a switch, driving the first threaded rod 7 to rotate, the movable block 8 can only reciprocate along the first threaded rod 7 in a straight line. This, in turn, drives the movable scraper 9 to thoroughly clean the inner wall of the baking tunnel oven 4. The movable scraper 9 is slidably connected to and tightly fitted with the inner wall of the baking tunnel oven 4, ensuring that the movable scraper 9 can fully contact the inner wall of the baking tunnel oven 4 during movement. When the movable block 8 drives the movable scraper 9 to move, it scrapes off dust and impurities from the inner wall, ensuring the cleanliness of the inside of the baking tunnel oven 4. The vacuum cleaner 12 is preferably a C3-L148B type. The vacuum cleaner 12 is started by a switch, and the vacuum cleaner 12 transmits power to the suction head 11 through the connecting pipe 13. The suction head 11 can remove the dust raised during the cleaning of the inside of the baking tunnel oven 4 through the through hole 10, further improving the cleaning effect. When it is necessary to collect the dust and impurities scraped off the conveyor belt 2, the adjusting plate 3 is rotated. The top of the adjusting plate 3 is rotatably connected to one end of the base 1. The adjusting plate 3 can rotate around the rotation point. During the rotation, the second threaded rod 16 on the outside of the adjusting plate 3 slides in the arc groove 15 on the outer side of the fixed plate 14. The arc groove 15 restricts the rotation range of the adjusting plate 3 and ensures the stability of the adjustment process. By adjusting the angle of the adjusting plate 3, it can accurately catch the dust and impurities scraped off the conveyor belt 2 and guide the impurities to slide into the external collection box for easy subsequent processing. After the adjusting plate 3 rotates and drives the second threaded rod 16 to slide into the arc groove 15 to the appropriate position, the nut 17 on the outer ring surface of the second threaded rod 16 is tightened to fit tightly against the fixed plate 14. The nut 17 and the fixed plate 14 are in close contact to generate friction and fix the adjusting plate 3 in the current position, ensuring that the adjusting plate 3 remains stable after the angle is adjusted and will not be displaced due to external forces or vibrations during equipment operation. The thread opening angle of the first threaded rod 7 and the second threaded rod 16 is 20°. To determine the degree of thread self-locking, the following formula must be met: Self-locking condition = coefficient of friction * tan(helix angle) ≥ 1.
