Description

Technical Field

[0001] This utility model relates to the field of food production technology, specifically to an edible film casting and forming device. Background Technology

[0002] Edible film is a thin film material that can be directly consumed and is commonly used in food packaging, coatings, carriers, or separators. Its key feature is that it does not need to be peeled off and discarded after use; it can be eaten directly with the food or dissolved. In the production process, edible film is typically formed using a casting machine. For example, the utility model patent CN208305545U, entitled "An Intelligent Edible Film Manufacturing Casting Machine," describes a production device where the film-forming slurry is conveyed through a hopper onto a rotating steel belt, dried with hot air to form a film, and finally detached from the steel belt.

[0003] However, existing casting machines have specific problems in practical applications. As pointed out in the patent "An Auxiliary Exhaust Mechanism for a Casting Machine" with authorization publication number CN216760284U, if the hot air in the oven blows directly onto the surface of the slurry, it will cause uneven heating of the slurry, inconsistent solidification in different parts, and may even cause the slurry to crack due to the impact of overheated air. This patent provides a solution aimed at avoiding the direct blowing of hot air onto the slurry.

[0004] However, it is worth noting that the above solution itself also has limitations. The utility model patent with authorization announcement number CN218170772U mentions that the exhaust auxiliary mechanism has the problem that the air volume of the exhaust pipe is inconvenient to adjust. Since the amount of hot air required for film formation of different raw materials is different, this will lead to unsatisfactory final molding effect of different slurries. Utility Model Content

[0005] This invention addresses the problem of difficulty in adjusting the airflow during hot air drying of edible film in the oven of a casting machine used for producing edible films. It provides an edible film casting and forming device that can conveniently adjust the airflow according to different slurries, thereby improving the film quality.

[0006] To solve the above problems, the technical solution of this utility model is: An edible film casting forming device includes a housing with through holes on its left and right side plates. A steel strip is rotatably mounted inside the housing, and a hopper for feeding material to the steel strip is located at the top of the housing. The device also includes a box and exhaust components. The box is fixed in a fixing hole in the top plate of the housing on the right side of the hopper. A hot air blower is connected to the top of the box. Exhaust components are spaced from left to right in the lower part of the housing. Each exhaust component includes an exhaust pipe and a control plate. Multiple exhaust pipes are spaced from front to back and connected to the bottom of the box. The exhaust pipes on the lower side of the box exhaust radially discharge air. Vertical plates are fixed to the bottom of the box on both sides of the multiple exhaust pipes. The two vertical plates and the box together form an air supply channel for the multiple exhaust pipes. A control plate is rotatably connected to the upper end of each vertical plate. A driving component is provided on the box. The driving component is used to drive the upper ends of the two control plates to contact each other and block the upper opening of the air supply channel, or to drive the upper ends of the two control plates to move away from each other.

[0007] Furthermore, each of the aforementioned air outlet pipes is a cylindrical body with an open top and a sealed bottom, and the upper end of each air outlet pipe passes through and is fixedly connected to the bottom plate of the box; air outlet holes are evenly distributed on the peripheral wall of the air outlet pipe on the lower side of the box; an exhaust pipe is fixed on the top plate of the shell between the box and the hopper, and the lower end of the exhaust pipe is lower than the lower end of the air outlet pipe; an observation window is provided on the rear side plate of the box.

[0008] Furthermore, each of the upright plates has a downward-facing arc-shaped groove at its upper end, and each arc-shaped groove has a rotating rod. The two ends of each rotating rod are rotatably connected to the front and rear side plates of the box body, respectively. The lower peripheral wall of each rotating rod slides in contact with the arc-shaped surface of the corresponding arc-shaped groove. Each rotating rod is connected to a control plate at its upper end, and the front and rear ends of each control plate slide in contact with the front and rear side plates of the box body, respectively.

[0009] Furthermore, the driving component includes a driving plate, which is located on the front side of the housing and is driven forward or backward by a screw. The front ends of the left and right rotating rods of each exhaust component are respectively connected to a driving rod one and a driving rod two. The front ends of the driving rod one and the driving rod two movably pass through the front side plate of the housing. A spiral groove one is provided on the circumference of the driving rod, and a spiral groove two with the opposite rotation direction to the spiral groove one is provided on the circumference of the driving rod two. A circular hole one is provided on the driving plate, which is slidably sleeved on the outside of the driving rod one. A driving post one is provided on the inner wall of the circular hole one, which extends into the spiral groove one. A circular hole two is provided on the driving plate, which is slidably sleeved on the outside of the driving rod two. A driving post two is provided on the inner wall of the circular hole two, which extends into the spiral groove two.

[0010] Furthermore, the screw is threadedly connected to the middle of the drive plate, the rear end of the screw is rotatably connected to the front side plate of the housing, and the front end is connected to a baffle. Guide rods are fixed on both the left and right sides of the front side of the housing, and the front end of each guide rod moves through the drive plate.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: This invention addresses the differences in hot air volume required for different slurries during film casting by adjusting the distance between the upper ends of two control plates on the air outlet via a drive plate. This controls the air intake volume of the air delivery channel, thereby regulating the amount of hot air entering the shell. Therefore, while hot air is radially blown out through multiple air outlets to dry the slurry on the steel strip, the amount of hot air entering the shell can be easily adjusted according to different slurries, ensuring the quality of the edible film.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6As shown, an edible film casting forming device includes a housing 1, which is a hollow cuboid with its lower opening sealed by a bottom plate. Through holes 2 are provided on the left and right side plates of the housing 1. A steel strip 3 is rotatably mounted inside the housing 1. A scraper 4 is fixed to the bottom surface of the right through hole 2, with the blade of the scraper 4 contacting the outer side of the right-side bend of the steel strip 3. Rotating shafts 5 are rotatably connected between the left and right sides of the front and rear side plates of the housing 1, respectively. Either rotating shaft 5 is driven to rotate by a motor 6. The two rotating shafts 5 are collectively fitted with the steel strip 3. A hopper 7 for feeding material to the steel strip 3 is provided at the upper part of the housing 1. The device also includes a box 8 and an exhaust system. The box 8 is a rectangular box with its upper opening sealed by a top plate. The box 8 is fixed to the top plate of the housing 1 on the right side of the hopper 7. Inside the fixed hole, the top of the housing 8 is connected to a hot air blower 9 for supplying hot air into the housing 8. The lower part of the housing 1 is provided with exhaust components from left to right. The exhaust components include an exhaust pipe 10 and a control plate 11. Multiple exhaust pipes 10 are connected from front to back to the bottom of the housing 8. The exhaust pipes 10 on the lower side of the housing 8 discharge air radially. The bottom of the housing 8 on the left and right sides of the multiple exhaust pipes 10 are fixed with upright plates 12. The two upright plates 12 and the housing 8 together form the air supply channel of multiple exhaust pipes 10. The upper end of each upright plate 12 is rotatably connected to a control plate 11. The housing 8 is provided with a driving component. The driving component is used to drive the upper ends of the two control plates 11 to contact each other and block the upper opening of the air supply channel, or to drive the upper ends of the two control plates 11 to move away from each other.

[0015] The hot air blower 9 is fixed to the top surface of the box body. The output end of the hot air blower 9 passes through the top plate of the box body and connects to the inside of the box body. The input end of the hot air blower 9 faces outward.

[0016] Each of the aforementioned air outlet pipes 10 is a cylindrical body with an open top and a sealed bottom. The upper end of each air outlet pipe 10 passes through and is fixedly connected to the bottom plate of the box body 8. Air outlet holes 13 are evenly distributed on the peripheral wall of the air outlet pipe 10 on the lower side of the box body 8. The air outlet holes 13 are circular holes with their inner ends facing the center of the air outlet pipe 10. An exhaust pipe 14 is fixed on the top plate of the shell 1 between the box body 8 and the hopper 7. The lower end of the exhaust pipe 14 is lower than the lower end of the air outlet pipe 10. An observation window 28 is provided on the rear side plate of the box body.

[0017] The upright plate 12 is a rectangular plate with its front and rear ends fixedly connected to the front and rear side plates of the box body 8, respectively. Each upright plate 12 has a downward-facing arc-shaped groove 15 at its upper end. Each arc-shaped groove 15 has a rotating rod 16 inside it. The two ends of each rotating rod 16 are rotatably connected to the front and rear side plates of the box body 8, respectively. The lower peripheral wall of each rotating rod 16 slides in contact with the arc-shaped surface of the corresponding arc-shaped groove 15. The rotating rod 16 is a round rod with a diameter that matches the diameter of the circle containing the arc-shaped groove 15. Each rotating rod 16 has a control plate 11 connected to its upper end. The front and rear ends of each control plate 11 slide in contact with the front and rear side plates of the box body 8, respectively.

[0018] The driving component includes a driving plate 17, which is located on the front side of the housing 8 and is driven forward or backward by a screw 25. The driving plate 17 is a rectangular plate. Each exhaust component has a driving rod 18 and a driving rod 30 connected to the front ends of its left and right rotating rods 16, respectively. The driving rods 18 and 30 are round rods with the same diameter as their corresponding rotating rods 16. The front ends of the driving rods 18 and 30 movably penetrate the front side plate of the housing 8. The driving rod 18 has a spiral groove 19 on its circumferential wall, with the front end of the spiral groove 19 penetrating the front end of the driving rod 18. The driving rod 30 has a spiral groove 20 on its circumferential wall with the opposite rotation direction to the spiral groove 19, with the front end of the spiral groove 20 penetrating the driving rod 30. At the front end of drive plate 17, there is a circular hole 21 that slides around drive rod 18. The inner wall of circular hole 21 is provided with drive post 22 that extends into spiral groove 19. Drive post 22 is a cylinder that slides in contact with spiral groove 19. Drive plate 17 is provided with a circular hole 23 that slides around drive rod 30. The inner wall of circular hole 23 is provided with drive post 24 that extends into spiral groove 20. Drive post 24 is a cylinder that slides in contact with spiral groove 20. Spiral groove 19 and spiral groove 20 are the same in shape and size, only their rotation direction is different. Spiral groove 19 and spiral groove 20 corresponding to the same exhaust component are symmetrical. Both drive rod 1 and drive rod 20 are connected to a stop block 29 at their front ends.

[0019] The screw 25 is threaded to the middle of the drive plate 17. The rear end of the screw 25 is rotatably connected to the front side plate of the housing 8, and the front end is connected to the baffle 26. Guide rods 27 are fixed on the left and right sides of the front side of the housing 8. The front end of each guide rod 27 moves through the drive plate 17.

[0020] In the initial state, the upper ends of the two control plates 11 on each exhaust component are in contact, and the two control plates 11 block the upper opening of the corresponding air supply channel; When adjusting the air volume of multiple air outlets 10 according to the hot air volume required for edible film forming slurry, the drive plate 17 can only move forward and backward because its left and right sides are limited by the guide rod 27. Rotating the screw 25 drives the drive plate 17 to move backward. When the drive plate 17 moves backward, the drive column 22 in each circular hole 21 moves backward, and the drive column 24 in each circular hole 23 moves backward. The drive column 22 presses against the spiral groove 19 on the corresponding drive rod 18, causing the drive rod 18 containing the spiral groove 19 to rotate counterclockwise. The drive column 24 presses against the spiral groove 20 on the corresponding drive rod 20. The drive rod 30, where the second spiral groove 20 is located, rotates clockwise. Therefore, the two rotating rods 16 on the same exhaust component are driven and rotate in opposite directions at the same time. The upper ends of the control plates 11 connected to the two rotating rods 16 gradually move away from each other. The distance between the upper ends of the two control plates 11 on the exhaust component can be observed through the observation window. When both control plates 11 are in a vertical state, the air intake volume of the air supply channel is the maximum. Therefore, this utility model can control the amount of hot air delivered by the hot air blower 9 into the air supply channel while keeping the power of the hot air blower 9 constant and within the same unit time. The hot air entering the air supply channel is discharged into the housing through multiple air outlet pipes connected at the bottom. During the production of edible film, the steel belt 3 is driven by the motor 6 to rotate clockwise. The hopper 7 discharges slurry to the top left of the steel belt 3. The slurry is spread evenly on the upper part of the outer ring surface of the steel belt 3. As the slurry spread evenly on the upper part of the outer top surface of the steel belt 3 moves to the right with the steel belt 3, the hot air blower 9 introduces hot air into the housing 8. The hot air in the housing 8 enters the air supply channel on the exhaust component through the gap between the upper ends of the two control plates 11 on each exhaust component. The hot air entering the air supply channel is radially discharged through multiple air outlet pipes 10 to dry the slurry on the upper side of the steel belt 3. The hot air in the housing 1 is discharged through the through holes 2 on both sides or the exhaust pipe 14. The dried slurry forms a film and moves to the right side of the steel belt 3 where it is bent and peeled off by the scraper 4. The edible film is separated from the steel belt 3 and proceeds to the subsequent winding process.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
