Description

Technical Field

[0001] This utility model relates to the technical field of dried fruit production equipment, specifically to a dried fruit conveyor belt. Background Technology

[0002] In dried fruit processing, the transfer of dried fruit from the steaming tank to the cooling tank and then to the drying box is mainly achieved by a continuous conveyor belt. However, after steaming and cooling, residual moisture and natural sugars on the surface of the dried fruit make it quite sticky. This leads to the accumulation of a large amount of sticky impurities on the conveyor belt, increasing the difficulty of cleaning; it also makes it difficult for the dried fruit to turn naturally during transport, affecting the uniformity of drying.

[0003] Chinese utility model patent CN217686476U discloses a dried fruit conveyor belt, including a main body of the device. The main body of the device includes a mounting box and a conveyor belt. Two sets of first support rods are installed at the bottom of the interior of the mounting box. The two sets of first support rods are mirror-symmetrical about the conveyor belt. A first mounting plate is installed at the top of the two sets of first support rods. A first vibration motor is installed at the top of the first mounting plate. The first vibration motor is installed at the bottom of the upper conveying section of the conveyor belt.

[0004] The aforementioned device reduces adhesion by installing a vibrating motor inside the device to generate continuous vibration on the conveyor belt surface. However, this vibration method easily leads to an imbalance in the tension of the conveyor belt. Long-term use will cause the conveyor belt to loosen, deform, or even deviate. This not only shortens the service life of the equipment but also requires frequent shutdowns for maintenance, significantly increasing the maintenance cost and production losses. Therefore, it has low practicality. Thus, we propose a fruit drying conveyor belt to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A dried fruit conveyor belt, comprising:

[0007] The conveyor bin has a conveyor belt installed in the middle of its inner side wall. A feed hopper is connected to one side of the top of the conveyor bin. The top of the conveyor bin has U-shaped notches at equal intervals. The bottom of the U-shaped notches is parallel to the surface of the conveyor belt. A material-pulling plate is slidably installed inside the U-shaped notches. A drying device is installed on the inner top wall of the conveyor bin at the intervals of the U-shaped notches. Fans are installed at intervals on the upper side wall of the conveyor bin near the feed hopper. A rectangular channel is constructed on the side wall of the conveyor bin away from the feed hopper, and a discharge hopper is fixedly inserted inside the rectangular channel. The discharge hopper is inclined and connected to the unloading end of the conveyor belt.

[0008] Furthermore, it also includes a feeding wheel, which is rotatably connected between the inner walls of the conveying bin and is located directly below the feeding hopper.

[0009] Furthermore, the feed plate is an obtuse-angled triangle.

[0010] Furthermore, connecting plates are fixed at both ends of the feeding plate.

[0011] Furthermore, the drying device is an infrared heating lamp.

[0012] Furthermore, the side wall of the conveying chamber away from the fan is constructed with a ventilation grille.

[0013] Furthermore, rollers are installed at the four corners of the bottom surface of the conveying chamber, and the rollers are self-locking omnidirectional wheels.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves the turning of dried fruit by setting a material-pushing plate in the U-shaped notch. Combined with the synergistic effect of the drying device and the fan, the dried fruit can be heated evenly and dried thoroughly during the conveying process, which greatly improves the quality of dried fruit drying, reduces the quality difference of dried fruit caused by uneven drying, and ensures the consistency and stability of dried fruit products. At the same time, the device structure is relatively simple and there are no complex vibrating parts, which avoids problems such as unbalanced tension, loosening, deformation or even deviation of the conveyor belt caused by vibration, and reduces the failure rate of the equipment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides a fruit drying conveyor belt, mainly to solve the problem that existing technologies often lead to uneven conveyor belt tension due to vibration, resulting in belt loosening, deformation, and even misalignment after long-term use. This not only shortens the equipment's lifespan but also requires frequent downtime for maintenance, significantly increasing maintenance costs and production losses, and thus has low practicality. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0024] A fruit drying conveyor belt 2 includes: a conveyor bin 1, a conveyor belt 2 installed in the middle of the inner side wall of the conveyor bin 1, a feed hopper 3 connected to the top side of the conveyor bin 1, U-shaped notches 101 evenly spaced on the top of the conveyor bin 1, the bottom of the U-shaped notches 101 being parallel to the belt surface of the conveyor belt 2, a material-pushing plate 4 slidably disposed inside the U-shaped notches 101, a drying device 5 installed at the intervals of the U-shaped notches 101 on the inner top wall of the conveyor bin 1, fans 6 spaced above the side wall of the conveyor bin 1 near the feed hopper 3, a rectangular channel constructed on the side wall of the conveyor bin 1 away from the feed hopper 3, and a discharge hopper 7 fixedly inserted inside the rectangular channel, the discharge hopper 7 being inclined and connected to the unloading end of the conveyor belt 2, and also includes a material-pushing wheel 8, the material-pushing wheel 8 being rotatably connected between the inner side walls of the conveyor bin 1, the material-pushing wheel 8 being located directly below the feed hopper 3.

[0025] Workflow Description:

[0026] Feeding stage: Dried fruit is fed into conveyor bin 1 through feeding hopper 3. A feeding wheel 8 is set directly below feeding hopper 3. The dried fruit first falls onto feeding wheel 8. The rotation of feeding wheel 8 (driven by the wind power of fan 6 and the gravitational potential energy of dried fruit) breaks up the dried fruit, preventing the dried fruit from piling up in large quantities and entering conveyor belt 2, so that the dried fruit can be more evenly distributed on conveyor belt 2.

[0027] Conveying and Drying Stage: After being broken up by the feeding roller 8, the dried fruit falls onto the conveyor belt 2. As the conveyor belt 2 moves, the fans 6, which are installed at intervals on the upper side wall near the feed hopper 3, start working to air dry the dried fruit, reducing the surface moisture content and stickiness. When the dried fruit moves with the conveyor belt 2 to the U-shaped notch 101, the feeding plate 4, which is slidably installed inside the notch, will lift the dried fruit, causing it to detach from the conveyor belt 2 and achieve a flipping effect. During the dried fruit conveying process, the drying device 5 on the top wall of the conveyor hopper 1 continues to work to dry the dried fruit. The fans 6 and the drying device 5 work together. On the one hand, the fans 6 accelerate the airflow, so that the heat generated by the drying device 5 can be applied to the dried fruit more evenly, improving the drying efficiency. On the other hand, the fast-flowing air also helps to remove the moisture evaporated from the surface of the dried fruit, avoiding localized humidity increases that affect the drying effect. Driven by the conveyor belt 2, the dried fruit passes through the feeding plate 4 multiple times, constantly flipping and receiving drying, ensuring the uniformity of drying.

[0028] Discharge stage: After being fully air-dried and oven-dried, the dried fruit moves to the unloading end of conveyor belt 2 and is discharged outward through the discharge hopper 7, which is connected to the unloading end of conveyor belt 2 and is set at an incline, thus completing the entire conveying and processing process.

[0029] like Figure 5 As shown, in some embodiments, the material-pushing plate 4 is an obtuse triangle. More specifically, the material-pushing plate 4 adopts an obtuse triangle. By utilizing the inclination angle of the hypotenuse of the triangle, the dried fruit is naturally lifted upwards when the conveyor belt 2 moves, so that it is separated from the belt surface and turned over.

[0030] like Figure 5 As shown, in some embodiments, connecting plates 401 are fixed at both ends of the material-pulling plate 4. More specifically, the connecting plates 401 form an integral component by connecting multiple material-pulling plates 4 in series. This series design simplifies the installation process. There is no need for individual positioning and fixing. Assembly can be completed simply by sliding the connecting plates 401 with the U-shaped notch 101, which greatly improves the installation efficiency. At the same time, the connecting plates 401 enhance the structural stability of the material-pulling plate 4 and prevent individual material-pulling plates 4 from tilting due to uneven force.

[0031] like Figure 4As shown, in some embodiments, the drying device 5 is an infrared heating lamp. More specifically, the infrared heating lamp has strong penetrating power and can directly act on the inside of the dried fruit, so that the moisture evaporates evenly from the inside out, avoiding the problem of the outside burning and the inside growing out caused by traditional heating methods. The infrared heating lamp is installed at the interval of the U-shaped notch 101, which can heat the dried fruit in all directions after it is turned over. With the airflow circulation formed by the fan 6, the infrared heat can quickly spread to all parts of the dried fruit, shortening the drying cycle. Compared with hot air drying, the infrared heating lamp has lower energy consumption, less heat loss, and the heating process is stable and controllable. It can accurately adjust the temperature to prevent the dried fruit from deteriorating due to overheating. At the same time, it simplifies the structure of the device and reduces maintenance costs.

[0032] like Figure 2 As shown, in some embodiments, the side wall of the conveying chamber 1 away from the fan 6 is constructed with a ventilation grille 102. More specifically, the ventilation grille 102 serves as an airflow channel to provide ventilation, forming a directional airflow circulation with the fan 6 to promptly discharge the water vapor generated during drying and maintain a dry environment inside the chamber. In addition, the ventilation grille 102 in this device can be replaced by a rectangular inspection port to provide a convenient passage for the maintenance of the conveyor belt 2, to clean the surface of the conveyor belt 2 of sticky impurities, or to inspect and repair components such as the material feeding plate 4 and the drying device 5.

[0033] like Figure 1 As shown, in some embodiments, rollers 9 are installed at the four corners of the bottom surface of the conveyor hopper 1. The rollers 9 are self-locking casters. More specifically, the casters can turn 360°, enabling the device to move flexibly in workshop aisles or complex layouts, easily adjust the working position, adapt to the docking requirements of different production lines, and ensure that the equipment is stably positioned during operation, preventing the conveyor belt 2 from shifting due to vibration during operation and ensuring conveying accuracy.

[0034] Working principle:

[0035] Material flipping principle: Utilizing the relative movement between the material flipping plate 4 and the conveyor belt 2, when the dried fruit moves with the conveyor belt 2 to the position of the U-shaped notch 101, the obtuse-angled triangular front end of the material flipping plate 4 first contacts the dried fruit. As the conveyor belt 2 continues to rotate, the material flipping plate 4 lifts the dried fruit, causing it to separate from the surface of the conveyor belt 2. Due to the movement of the material flipping plate 4 and the gravity of the dried fruit itself, the dried fruit will change position after being lifted, achieving the flipping effect.

[0036] Drying Principle: The drying device 5 uses infrared heating lamps. Infrared rays have a thermal effect and can directly radiate to the surface of the dried fruit, causing the internal molecules of the dried fruit to vibrate more intensely and generate heat, thereby drying the dried fruit. The fan 6 is installed on the upper side wall near the feed hopper 3. The air blown out by the fan flows along the conveyor belt 2, accelerating the air circulation speed in the chamber. On the one hand, the fast-flowing air can evenly carry the heat generated by the infrared heating lamps to all parts of the dried fruit, improving the heat transfer efficiency and allowing the dried fruit to be heated more quickly and evenly. On the other hand, the flowing air can promptly remove the water vapor evaporated from the surface of the dried fruit due to heating, maintaining the humidity difference on the surface of the dried fruit, which is conducive to the continuous evaporation of moisture from the inside of the dried fruit, thereby improving the drying efficiency. The ventilation grille 102 is set on the side wall of the conveyor chamber 1 away from the fan 6, forming an air circulation channel in the chamber. Fresh air enters from the fan 6 end, carries away the water vapor in the drying area, and then exits from the ventilation grille 102 end, maintaining good air circulation in the chamber and ensuring the continuous and stable operation of the drying process.
