Description

Technical Field

[0001] This utility model relates to the technical field of Polygonatum processing equipment, specifically a drying system applied to a Polygonatum production line. Background Technology

[0002] During the processing of Polygonatum sibiricum, the slender Polygonatum sibiricum is cut into granules along its length by a cutting machine, and then transported to a conveyor-type dryer for drying via a conveyor belt inclined to one side of the cutting machine. However, when the granular Polygonatum sibiricum falls from the cutting machine onto the conveyor belt, due to inertia and the limitation of the discharge position, it tends to accumulate on the side of the conveyor belt closest to the cutting machine (i.e., unilateral bias). When the material is conveyed to the feed end of the dryer, this unilateral accumulation phenomenon causes the granular Polygonatum sibiricum to tilt and gather to one side in the feed area. To improve the uniformity of the subsequent spreading mechanism, currently an operator is required at the feed end of the dryer to manually spread the accumulated Polygonatum sibiricum granules periodically with a shovel. However, this method has significant drawbacks: manual intervention is required continuously and repeatedly, resulting in high labor intensity and low efficiency; at the same time, manual spreading makes it difficult to accurately control the uniformity of particle distribution, easily causing uneven thickness of the spread material, which in turn affects the consistency of heating and ventilation of the Polygonatum sibiricum granules during the drying process, ultimately reducing the uniformity of the dried quality. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a drying system applied to a Polygonatum production line.

[0004] The technical solution of this utility model is as follows:

[0005] A drying system for a Polygonatum production line includes a belt conveyor and a conveyor-type dryer arranged sequentially, as well as a cutter located on one side of the belt conveyor.

[0006] As the core technical concept of this utility model, a material spreading mechanism is provided between the discharge port of the cutting machine and the conveyor belt of the belt conveyor. The material spreading mechanism includes a support and a slide plate installed on it. The slide plate is inclined along the width direction of the conveyor belt, with one end located below the discharge port and the other end inclined downwards towards the upper surface of the conveyor belt. The width of the slide plate on the side closer to the discharge port is greater than the width on the side away from the discharge port.

[0007] Furthermore, the slide plate is a right-angled trapezoid. To ensure the material spreading range and prevent the polysaccharide granules from spilling, the vertical projection of the slide plate is located inside the conveyor belt.

[0008] As one implementation method, the tilt angle of the slide plate along the width direction of the conveyor belt is adjustable.

[0009] As another implementation method, the angle formed by the skateboard and the vertical plane containing the width of the conveyor belt can be adjusted.

[0010] Preferably, the tilt angle of the slide plate along the width of the conveyor belt and the angle formed with the vertical plane containing the width of the conveyor belt are both adjustable.

[0011] Specifically, a fixing component is provided on the underside of the slide plate, and the support includes a vertically arranged stand and an angle adjustment component connected to the fixing component at its upper end. The tilt angle of the slide plate along the width direction of the conveyor belt and the size of the angle formed with the vertical plane containing the width of the conveyor belt are both adjusted by the angle adjustment component.

[0012] Furthermore, a reinforcing rod that is connected to a fastener is also fixedly connected to the underside of the skateboard.

[0013] Furthermore, the vertical height of the skateboard is adjustable.

[0014] As described above, in a drying system applied to a Polygonatum production line, the slide plate has an upper baffle extending upward from the right-angled edge in the width direction of the conveyor belt.

[0015] Furthermore, the slide plate and the upper baffle have an extension extending outward on the side near the discharge port, and the side of the extension opposite to the upper baffle has an upwardly extending lower baffle.

[0016] Preferably, the skateboard, the upper baffle, and the lower baffle are integrally bent and formed.

[0017] This invention, through the structural design and inclined arrangement of the sliding plate, allows the Polygonatum odoratum granules to naturally disperse and slide down onto the upper surface of the conveyor belt, effectively solving the problem of unilateral bias, achieving uniform material distribution, replacing manual intervention, improving the consistency of heating and ventilation of the Polygonatum odoratum granules in the subsequent drying process, and ultimately improving the uniformity of the dried quality of the Polygonatum odoratum granules.

[0026] Combination Figures 1-3 This embodiment provides a drying system for a Polygonatum production line, including a belt conveyor and a conveyor dryer arranged sequentially, and a cutter located on one side of the belt conveyor.

[0027] Among them, the cutting machine, belt conveyor and conveyor dryer are all existing technologies. The cutting machine is used to cut Polygonatum into granules. The belt conveyor is set at an inclination to transport and lift the Polygonatum granules processed by the cutting machine to fall naturally into the conveyor dryer. The conveyor dryer is used to dry the granular Polygonatum. For example, a forage drying device for forage processing with patent publication number CN222418417U, the specific structure and principle of which will not be described in detail here.

[0028] As the core technical concept of this utility model, a material spreading mechanism is provided between the discharge port 1 of the cutting machine and the conveyor belt 2 of the belt conveyor. The material spreading mechanism includes a support 3 and a slide plate 4 set on it. The slide plate 4 is inclined along the width direction of the conveyor belt 2, with one end located below the discharge port 1 and the other end inclined downward pointing towards the upper surface of the conveyor belt 2. The width of the slide plate 4 on the side closer to the discharge port 1 is greater than the width on the side away from the discharge port 1.

[0029] During use, the granulated Polygonatum sibiricum exits from the discharge port 1 of the cutting machine and slides down the slide plate 4 onto the conveyor belt 2 of the belt conveyor. Because the slide plate 4 is tilted downwards from the side where the discharge port 1 is located, pointing towards the upper surface of the conveyor belt 2, and the width of the side of the slide plate 4 near the discharge port 1 is greater than the width of the side away from the discharge port 1, the Polygonatum sibiricum granules can naturally disperse and slide down the slide plate 4 onto the upper surface of the conveyor belt 2, effectively solving the problem of unilateral bias, realizing automated and uniform material spreading, replacing manual intervention, improving the heat and ventilation consistency of the Polygonatum sibiricum granules in the subsequent drying process, and ultimately improving the uniformity of the dried quality of the Polygonatum sibiricum granules.

[0030] Specifically, the slide plate 4 is a right-angled trapezoid, and its vertical projection is located inside the conveyor belt 2. This ensures that the vertical projection of the slide plate 4 is always within the effective working area of ​​the conveyor belt 2, thus guaranteeing the material spreading range while preventing the spillage of the Polygonatum sibiricum particles.

[0031] Optionally, the tilt angle of the slide plate 4 along the width of the conveyor belt 2 is adjustable. This allows the system to adjust the sliding trajectory according to the different particle sizes of Polygonatum odoratum particles, adapting to various processing conditions and improving the system's versatility.

[0032] Optionally, the angle formed by the slide plate 4 and the vertical plane containing the width of the conveyor belt 2 is adjustable. This allows the system to control the lateral distribution range of the Polygonatum odoratum particles according to their different sizes, ensuring that the particles are evenly covered in the width direction of the conveyor belt 2 and avoiding local accumulation.

[0033] Combination Figure 3 and Figure 4 The slide plate 4 is provided with a fixing member 35 on its lower side. The bracket 3 includes a vertically arranged stand and an angle adjustment component connected to the fixing member 35 at its upper end. The tilt angle of the slide plate 4 along the width direction of the conveyor belt 2 and the size of the angle formed with the vertical plane where the width of the conveyor belt 2 is located can be adjusted by the angle adjustment component.

[0034] The angle adjustment component allows for precise adjustment of the skateboard's spatial posture. A single mechanism can simultaneously adjust both angles, simplifying the operation process and improving adjustment accuracy.

[0035] The support frame includes two upright plates 32 arranged opposite each other along the length of the conveyor belt 2, and a base plate 31 located on the underside of the two upright plates 32. The base plate 31 is fixed to the ground. Of course, the support frame can also be set on the frame of the cutting machine or belt conveyor. Here, in order to avoid the vibration of the cutting machine or belt conveyor affecting the slide plate 4 during operation, the support frame is fixed to the ground.

[0036] The angle adjustment mechanism includes a first connecting rod 33 spirally disposed between two upright plates 32, a second connecting rod 34 vertically disposed in the middle of the first connecting rod 33, a fixing member 35 spirally connected to the inside of the second connecting rod 34 near the cutting machine, and locking members 36 spirally disposed on the upright plates 32 and the second connecting rod 34 respectively, with their inner ends pressing against the first connecting rod 33 and the fixing member 35. The locking member 36 can be a set screw.

[0037] Combination Figure 4 When adjusting the tilt angle of the slide plate 4 along the width direction of the conveyor belt 2, turn the locking member 36 on the vertical plate 32 so that the inner end of the locking member 36 moves away from the first connecting rod 33. Rotate the first connecting rod 33 to adjust the angle. Then tighten the locking member 36 so that its inner end is pressed against the first connecting rod 33. When adjusting the angle between the slide plate 4 and the vertical plane containing the width of the conveyor belt 2, turn the locking member 36 on the second connecting rod 34 so that the inner end of the locking member 36 moves away from the fixed member 35. Rotate the fixed member 35 to adjust the angle. Then tighten the locking member 36 so that its inner end is pressed against the fixed member 35. The structure is simple and easy to process, and the whole adjustment process is convenient and quick.

[0038] Combination Figure 4A reinforcing rod 37, which is connected to the fixing member 35, is also fixedly connected to the underside of the slide plate 4 to improve the structural strength of the slide plate 4. The reinforcing rod 37 enhances the connection strength between the slide plate 4 and the bracket 3, prevents deformation during long-term use, and ensures the stability of the material laying and the service life of the system. Furthermore, the cross-sectional shape of the first connecting rod 33, the second connecting rod 34, the fixing member 35, and the reinforcing rod 37 are all circular.

[0039] To accommodate the discharge port 1 height of different cutting machine models, enhance equipment compatibility, and reduce production line modification costs, the vertical height of the slide plate 4 is adjustable.

[0040] Specifically, the upright plate 32 includes an upper upright plate 32 and a lower force plate. The lower force plate has a vertically elongated hole, and the upper force plate has a bolt passing through the elongated hole. The bolt and the elongated hole are vertically slidingly engaged. The first connecting rod 33 is connected between the upper ends of the two upper upright plates 32, and a locking nut is also spirally provided on the first connecting rod 33 located at both ends of the two upper upright plates 32 to improve the connection stability.

[0041] Combination Figure 5 The slide plate 4 has an upper baffle 5 extending upward from the right-angled edge of the conveyor belt 2 in the width direction. This prevents particles from overflowing from one side of the right angle and allows all particles to slide stably from the inclined side onto the conveyor belt 2, thereby improving the uniformity of the material distribution.

[0042] The slide plate 4 and the upper baffle 5 have an extension extending outward from the side near the discharge port 1. The side of the extension opposite to the upper baffle 5 has an upwardly extending lower baffle 6. The extension and the lower baffle 6 form a flow guiding channel, which has a buffering and diversion effect on high-density material feeding conditions, and further optimizes the uniformity of distribution.

[0043] The thickness of the slide plate 4, the upper baffle 5, and the lower baffle 6 is 1.5mm-5mm. The slide plate 4, the upper baffle 5, and the lower baffle 6 are formed by bending in one piece to improve the overall structure and stability, and to facilitate processing and manufacturing.
