Description

Technical Field

[0001] This utility model relates to the field of vermicelli drying technology, specifically a vermicelli drying and packaging equipment. Background Technology

[0002] Vermicelli drying and packaging equipment is used in the post-processing stage of vermicelli production. It can realize automated drying and quantitative packaging, and the equipment is compatible with vermicelli of different specifications. It can stably control the drying quality and packaging accuracy. It is widely used in small and medium-sized vermicelli processing plants, helping to achieve standardized and large-scale production.

[0003] Chinese patent discloses a vermicelli drying oven (authorization announcement number CN222364361U), including an oven body equipped with temperature and humidity sensors. The front of the oven body has a sealable and lockable door, and the top of the oven body has an exhaust pipe. The top of the oven body has two parallel C-shaped steel slide rails for hanging drying racks, and the bottom has several heating tubes evenly distributed throughout. The drying rack includes two parallel moving rods, with several rollers evenly distributed along the length of each rod on both sides. The bottom of the two moving rods has several U-shaped rods evenly distributed along the length of each rod for hanging vermicelli. Several rollers are used to roll within corresponding C-shaped steel slide rails. This patented technology facilitates the removal and placement of the drying rack by using a moving rod and rollers on the moving rod to roll on the C-shaped steel slide rails, improving the overall ease of use. However, this patent only uses U-shaped rods to suspend the vermicelli. Because the vermicelli bends and twists spirally due to uneven shrinkage during moisture evaporation, especially long or soft vermicelli, it is more susceptible to distortion and deformation during the drying process due to hot air disturbance. Twisted vermicelli will lead to increased measurement errors during subsequent packaging, easy jamming, and thus increased packaging time and reduced production efficiency.

[0004] Therefore, this utility model provides a vermicelli drying and packaging equipment to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a vermicelli drying and packaging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vermicelli drying and packaging device includes a feeding platform, a discharging platform, a drying chamber, and a packaging machine. The discharging platform is located on one side of the feeding platform, and both of them have a drive belt for driving the vermicelli to move fixedly installed on their upper surfaces. The drying chamber is located between the feeding platform and the discharging platform. A separating drive belt for distributing vermicelli is fixedly connected to the side of the discharging platform away from the drying chamber, and one end of the separating drive belt is fixedly connected to the packaging machine.

[0008] The drying chamber has a rotating door on one side for opening, and a drying host is fixedly connected to the other side for providing hot drying air into the chamber. The drying chamber has slots at both ends near the loading and unloading platforms for allowing the vermicelli to pass through. Multiple sets of rollers for assisting in conveying the vermicelli are rotatably installed inside the drying chamber. Multiple support plates for supporting the vermicelli are fixedly installed on the inner wall of the drying chamber. Each support plate has a pressing component on its top. The support plates and pressing components work together to apply pressure to the vermicelli, effectively preventing twisting and deformation during the drying process.

[0009] As a further embodiment of this utility model, the extrusion assembly includes a rotating tube, both ends of which are rotatably connected to the inner wall of the drying chamber. A pressure plate for pressing the vermicelli is installed on the outer wall of the rotating tube. Multiple pressure plates are provided and symmetrically and evenly distributed on the outside of the rotating tube. A drive assembly for pushing the pressure plates to expand is fixedly installed in the inner cavity of the rotating tube. The drive assembly pushes multiple pressure plates to expand synchronously, ensuring that the pressure plates fit the vermicelli on the top surface of the support plate and apply a squeezing action to them to regulate the shape of the vermicelli.

[0010] As a further embodiment of this utility model, the driving component includes an airbag, which is installed in the inner cavity of the rotating tube. Both ends of the airbag are fixedly connected to moving parts, and the outer wall of each moving part is rotatably connected to multiple transmission rods for pushing the pressure plate outward.

[0011] As a further embodiment of this utility model, each of the pressure plates is slidably connected to an expansion plate inside, and the expansion plate is located between two adjacent pressure plates to prevent gaps from appearing after the pressure plates expand. Both ends of each expansion plate are fixedly connected to the inner wall of the pressure plate by a tension spring.

[0012] As a further embodiment of this utility model, a starch coating box is fixedly installed on the top surface of the feeding platform for uniformly coating the outer surface of the vermicelli with edible starch to form an isolation layer, which can effectively prevent the vermicelli from sticking together during the subsequent pressing process by the extrusion component. The inner cavity of the starch coating box is rotatably connected to two sets of coating rollers through a pin shaft, and the vermicelli passes through the two sets of coating rollers to achieve uniform starch coating.

[0013] As a further embodiment of this utility model, a cutting box is fixedly installed on the top surface of the feeding platform for cutting the dried vermicelli to a fixed length. An electric push rod is fixedly connected to the inner wall of the cutting box, and a moving frame is fixedly connected to the output end of the electric push rod. Multiple cutters for cutting vermicelli are fixedly installed at the bottom end of the moving frame by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When this utility model is used, the airbag driving the pressure plate of the extrusion component applies uniform pressure to the vermicelli, and forms a stable support surface with the support plate. When the vermicelli shrinks unevenly due to moisture evaporation or is disturbed by hot air during the drying process, the pressure plate, through the linkage of the transmission rod, fits the vermicelli surface in real time and applies a reverse constraint force to counteract the shrinkage stress and wind disturbance, forcibly maintaining the straight shape of the vermicelli. At the same time, the expansion plate fills the gap of the pressure plate to form a continuous pressing plane, avoiding local extrusion failure. Especially for long or soft vermicelli, it can effectively prevent them from bending or spiral twisting, thus solving the subsequent packaging problem caused by irregular shape.

[0016] 2. When this utility model is used, the heating tubes inside the pressure plate and expansion plate simultaneously heat the vermicelli during the extrusion process. The surface temperature is increased through conduction, which accelerates the evaporation of moisture and shortens the drying time. Uniform heating can reduce the internal stress difference of the vermicelli and avoid the aggravation of shrinkage and deformation due to uneven temperature. The vermicelli after shaping has a regular shape, which can reduce the probability of material jamming and allow the vermicelli to pass smoothly through the conveying and packaging structure of the packaging machine, shortening the packaging time and improving production efficiency. Combined with the starch coating box forming an anti-stick isolation layer on the surface of the vermicelli in advance, it further ensures the smoothness of extrusion shaping, avoids shape damage caused by adhesion, and ensures the stability of the device operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a vermicelli drying and packaging equipment includes a feeding platform 1, a discharging platform 2, a drying box 3, and a packaging machine 4. The discharging platform 2 is located on one side of the feeding platform 1, and both of them are fixedly installed with a drive transmission belt 5 for driving the vermicelli to move. The drying box 3 is located between the feeding platform 1 and the discharging platform 2. A separating transmission belt 6 for distributing vermicelli is fixedly connected to the side of the discharging platform 2 away from the drying box 3, and one end of the separating transmission belt 6 is fixedly connected to the packaging machine 4.

[0029] A door 301 for opening the drying chamber 3 is rotatably installed on one side of the drying chamber 3 via a pin shaft, and a drying host 302 is fixedly connected to the other side of the drying chamber 3 via a pipe. It has integrated heating and air supply functions and is used to provide drying hot air into the drying chamber 3 to drive the drying process. The drying chamber 3 has slots for the passage of vermicelli at both ends near the loading platform 1 and the unloading platform 2. Multiple sets of rollers 303 for assisting in conveying vermicelli are rotatably installed in the inner cavity of the drying chamber 3 via a pin shaft. Multiple support plates 304 for supporting vermicelli are fixedly installed on the inner wall of the drying chamber 3. Each support plate 304 has an extrusion component 7 installed on its top. The support plate 304 and the extrusion component 7 work together to apply pressure to the vermicelli, effectively preventing the vermicelli from twisting and deforming during the drying process.

[0030] Specifically, both the drive belt 5 and the separator belt 6 are composed of a conveyor belt and a pressure roller. The pressure roller is located at the top of the conveyor belt, and there is a gap between the two to facilitate the passage of the vermicelli. Two rotating shafts are installed in the inner cavity of the conveyor belt. One end of one of the rotating shafts is connected to the motor via a belt. The other end of the rotating shaft and one end of the pressure roller are fixedly fitted with gears. The two gears mesh with each other to ensure that the conveyor belt and the pressure roller rotate synchronously. (The specific structure is existing technology and will not be described in detail here.)

[0031] More specifically, a monitoring meter for displaying changes in internal values ​​of the drying chamber 3 is fixedly installed on the side of the drying chamber 3 near the opening and closing door 301. A main control box for controlling the overall autonomous operation of the drying host 302 is fixedly installed on the outer wall. The packaging machine 4 consists of a conveying structure, a packaging film supply structure, and a sealing structure. It can orderly convey the dried and separated vermicelli and complete the packaging film wrapping, sealing, and other packaging processes to achieve standardized packaging. At the same time, the separating conveyor belt 6 can orderly separate the vermicelli during the vermicelli conveying process, providing neatly arranged materials for subsequent drying, packaging, and other processes. (Both the packaging machine 4 and the separating conveyor belt 6 are existing technologies, and their specific structures will not be described in detail here.)

[0032] Please see Figure 2 , Figure 3 , Figure 4 The extrusion assembly 7 includes a rotating tube 701. Both ends of the rotating tube 701 are rotatably connected to the inner wall of the drying chamber 3 via pins. The outer wall of the rotating tube 701 is equipped with a pressing plate 702 for pressing the vermicelli. The pressing plate 702 is close to the top surface of the support plate 304. Multiple pressing plates 702 are provided and are symmetrically and evenly distributed on the outside of the rotating tube 701. The inner cavity of the rotating tube 701 is fixedly equipped with a driving assembly for pushing the pressing plate 702 to expand. The driving assembly pushes multiple pressing plates 702 to expand synchronously, ensuring that the pressing plate 702 fits the vermicelli on the top surface of the support plate 304 and applies a squeezing action to it to regulate the shape of the vermicelli.

[0033] The drive assembly includes an airbag 703, which is installed in the inner cavity of the rotating tube 701. Both ends of the airbag 703 are fixedly connected to moving parts 704. The outer wall of each moving part 704 is rotatably connected to multiple transmission rods 705 for pushing the pressure plate 702 outward through pins. The transmission rods 705 and the pressure plate 702 are rotatably connected through pins to form a transmission structure.

[0034] Specifically, a fixing ring 706 is fixedly connected to the inner wall of the rotating tube 701. The fixing ring 706 is fixedly sleeved on the outer wall of the airbag 703 and is located at the center of the airbag 703. It is used to position the airbag 703 so that when the airbag 703 expands or contracts, it can drive the moving parts 704 connected at both ends to move synchronously. When the airbag 703 expands or contracts, the fixing ring 706 can drive the moving parts 704 at both ends to move synchronously to the sides or center. The transmission rod 705 pushes the pressure plate 702 to expand outward or contract inward synchronously, so as to achieve uniform compression or release of the vermicelli on the support plate 304 and ensure that the vermicelli is in a regular shape.

[0035] More specifically, the airbag 703 has multiple fixed rods 707 installed on its exterior, and both ends of the fixed rods 707 are fixedly connected to the inner wall of the rotating tube 701 to form a support frame. A storage spring 708 is fixedly installed between the two sets of moving parts 704, and the storage spring 708 is sleeved on the outside of the fixed rods 707. The elastic tension drives the two sets of moving parts 704 to move closer to each other, thereby controlling the transmission rod 705 to drive the pressure plate 702 to expand outward, so that it fits tightly against the vermicelli on the top surface of the support plate 304 to achieve stable pressing. At the same time, the expansion range of the pressure plate 702 can be adaptively adjusted according to the vermicelli of different thicknesses, effectively improving the versatility and operational reliability of the equipment.

[0036] More specifically, a gas supply pipe 709 is fixedly connected to the axis of the rotating tube 701, and the gas supply pipe 709 passes through each air bag 703 in sequence and is connected to the inner cavity of the air bag 703. An air pump 710 for supplying gas is fixedly installed on the outer wall of the drying box 3, and the gas supply end of the air pump 710 is fixedly connected to the gas supply pipe 709. The opening and closing state of the pressure plate 702 can be precisely controlled by the gas pressure to meet the noodle shaping needs under different working conditions.

[0037] Please see Figure 5 Each pressure plate 702 has an expansion plate 711 slidably connected inside, and the expansion plate 711 is located between two adjacent pressure plates 702 to prevent gaps from appearing after the pressure plates 702 expand. Both ends of each expansion plate 711 are fixedly connected to the inner wall of the pressure plate 702 by a tension spring 713.

[0038] Specifically, when the pressure plate 702 expands outward under the action of the driving component, the expansion plate 711 unfolds synchronously under the elastic constraint of the tension spring 713, filling the gap between the pressure plates 702 and forming a continuous pressing plane, so as to avoid the rice noodles from deforming or shifting due to discontinuous extrusion during the drying process, and to ensure the uniformity and stability of the shaping effect.

[0039] More specifically, heating tubes 712 are fixedly installed in the inner cavities of the pressure plate 702 and the expansion plate 711. The heating tubes 712 can simultaneously heat the vermicelli during the extrusion process, thereby increasing the surface temperature of the vermicelli through conduction and accelerating moisture evaporation. At the same time, uniform heating can reduce local stress caused by extrusion and prevent the vermicelli from deforming due to uneven temperature, further ensuring the regularity of the vermicelli shape and the drying efficiency during the drying process.

[0040] Please see Figure 5 The top surface of the feeding platform 1 is fixedly equipped with a starch coating box 8, which is used to evenly coat the outer surface of the vermicelli with edible starch to form an isolation layer. This can effectively prevent the vermicelli from sticking together during the subsequent pressing process by the extrusion component 7, effectively ensuring the smooth progress of the extrusion and shaping process, avoiding damage to the shape of the vermicelli due to sticking, reducing the frequency of manual cleaning of the equipment, improving production efficiency and product quality stability, and providing standardized material units for subsequent automated packaging by precisely controlling the cutting length, effectively improving packaging efficiency and specification consistency. The inner cavity of the starch coating box 8 is rotatably connected to two sets of coating rollers 801 through a pin shaft, and the vermicelli passes between the two sets of coating rollers 801 to achieve uniform starch coating.

[0041] Specifically, a starch storage tank 802 is installed on one side of the feeding platform 1. A conveying pipe 803 is fixedly connected to the top of the starch storage tank 802 to transport the starch in the starch storage tank 802 to the area of ​​the coating roller 801. The rotation of the coating roller 801 evenly attaches the starch to the surface of the vermicelli, forming an anti-sticking isolation layer. There are gaps between adjacent coating rollers 801. The gaps ensure that the upper layer of starch falls naturally to the lower layer under the action of gravity. The overall width of the vermicelli is smaller than the gap between the coating rollers 801, so that the falling starch can fully cover the bottom surface of the vermicelli. This ensures that the upper and lower surfaces of the vermicelli are evenly coated with starch, effectively avoiding the problem of sticking due to insufficient contact on the bottom surface.

[0042] Please see Figure 6 A cutting box 9 is fixedly installed on the top surface of the feeding platform 2 for cutting the dried vermicelli to a fixed length. An electric push rod 901 is fixedly connected to the inner wall of the cutting box 9. A moving frame 902 is fixedly connected to the output end of the electric push rod 901. Multiple cutters 903 for cutting vermicelli are fixedly installed at the bottom end of the moving frame 902 by bolts. The moving frame 902 is driven to rise and fall vertically by the electric push rod 901, which drives the cutters 903 to perform precise cutting of vermicelli.

[0043] The working principle of this utility model is as follows:

[0044] When using this utility model, firstly, the vermicelli is manually pulled through the starch coating box 8, the drying box 3 and the two sets of drive transmission belts 5 in sequence. Then, the drive transmission belts 5 are started to operate and the vermicelli is conveyed forward. At the same time, when the vermicelli moves, it drives the two sets of coating rollers 801 to rotate, so that the edible starch delivered by the starch storage tank 802 through the conveying pipe 803 is evenly coated on the surface of the vermicelli to form an anti-stick isolation layer and prevent sticking during subsequent extrusion.

[0045] Then, the starch-coated vermicelli is fed into the drying chamber 3 via the drive belt 5, enters the inner cavity through the slot, and the drive drying host 302 delivers hot air into the drying chamber 3 through the pipe to start the drying process. The rollers 303 in the inner cavity assist in conveying the vermicelli, making it spread flat on the support plate 304. Then, the air pump 710 supplies air to the air supply pipe 709, driving the air bag 703 to expand or contract. When the air bag 703 expands, it pushes the moving parts 704 at both ends to move to both sides. The transmission rod 705 drives the pressure plate 702 to expand outward, fits the vermicelli on the support plate 304 and applies pressure to prevent twisting and deformation during drying. The expansion plate 711 in the pressure plate 702 fills the gap between two adjacent pressure plates 702 through the tension spring 713 to form a continuous pressing surface. At the same time, the heating tube 712 heats the vermicelli synchronously, accelerates the evaporation of moisture and reduces local stress.

[0046] Next, the dried vermicelli is fed out through the trough at the other end of the drying box 3 and conveyed to the cutting box 9 by the drive transmission belt 5 of the unloading platform 2. The moving frame 902 is driven to rise and fall vertically by the electric push rod 901, which drives the cutter 903 to cut the vermicelli to a fixed length. The cut vermicelli is then conveyed to the separating transmission belt 6 on one side of the unloading platform 2, which divides the vermicelli into quantitative units in an orderly manner, providing regular materials for packaging.

[0047] Finally, the separated vermicelli is fed into the packaging machine 4 by the separating conveyor belt 6. The conveying structure, packaging film supply structure and sealing structure of the packaging machine 4 work together to complete the processes of conveying vermicelli, wrapping with packaging film and sealing, so as to achieve standardized packaging.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
