Description

Technical Field

[0001] This application relates to the field of transportation equipment, and more particularly to a raw material conveying mechanism for processing bamboo leaves. Background Technology

[0002] The processing of reed leaves is a crucial step in the food packaging and zongzi (sticky rice dumpling) production industries. A typical process includes washing, draining, drying, sorting, and packaging. The drying process is particularly critical. The washed, damp reed leaves are evenly laid out in baskets and then transported by trolleys into multi-layer drying chambers for hot air drying. Traditional drying chambers typically employ a multi-layer rack structure to improve space utilization, and the accompanying transport trolleys are also designed with multiple layers to transport multiple baskets of reed leaves at once, matching the height of the drying chamber.

[0003] However, most of the transport trolleys currently in use are fixed, multi-layered frame structures, lacking lifting or auxiliary loading and unloading functions. In practice, workers must lift the heavy baskets of bamboo leaves one by one to the upper level of the transport trolley or drying box, which is labor-intensive and inefficient. Especially since the upper level of the drying box is quite high, manual handling is not only time-consuming and laborious but also poses safety hazards, easily leading to worker fatigue and even muscle injuries. In addition, repeated loading and unloading can cause the bamboo leaf baskets to deform or the bamboo leaves to scatter, affecting the processing quality.

[0004] To address the aforementioned issues, there is an urgent need for a new type of raw material conveying mechanism for bamboo leaf processing. This mechanism should optimize the structural design of the transport trolley to reduce the intensity of manual handling, improve the loading and unloading efficiency of bamboo leaf baskets, and adapt to the operational requirements of multi-layer drying boxes, thereby meeting the automation and efficiency requirements of modern bamboo leaf processing. Summary of the Invention

[0005] This application provides a raw material conveying mechanism for processing bamboo leaves, which solves the technical problem in the prior art where workers need to lift heavy bamboo leaf baskets one by one to the upper position of the transport trolley or drying box, resulting in high labor intensity and low efficiency. It enables the bamboo leaf baskets to slide freely between the upper and lower layers without requiring workers to lift the bamboo leaf baskets to the upper layer, thereby reducing labor intensity and improving the transportation efficiency of bamboo leaves.

[0006] This application provides a raw material conveying mechanism for processing bamboo leaves, comprising: an outer frame movable frame, serving as a basic frame and freely movable; placement trays for placing bamboo leaf baskets, arranged in a double row and double layer within the outer frame movable frame, wherein the two placement trays in the upper layer are hinged at opposite ends to the outer frame movable frame, and at adjacent ends are swayable; one placement tray in the lower layer is horizontally fixed to the outer frame movable frame, and the other placement tray has the same hinged and swayable state as the placement tray directly above it; a switching component one, connected between the two placement trays in the upper and lower layers that are inclined and both hinged to the outer frame movable frame, and used to switch the two placement trays between parallel and inclined collinear arrangements; a switching component two, connected to the upper placement tray not connected to the switching component one, and connected to the end of the placement tray away from the hinged end to the outer frame movable frame; a synchronization component, connected between the switching component one and the switching component two, and used for the synchronous movement of the switching component one and the switching component two; and a drive component, used to drive the synchronization component to operate.

[0007] Furthermore, the bottom of the two placement trays connected to the first switching component is fixed with a slide rail at one end, and a slider is slidably connected to the slide rail, and a transition block is fixedly connected to the slider; the first switching component includes: a long connecting rod, both ends of which are respectively hinged to the transition blocks at the bottom of the two placement trays connected to the first switching component; a support base, which is fixedly installed on the outer frame movable frame, and the support base is located in the middle position of the gap between the two placement trays when the two placement trays connected to the first switching component are in an inclined collinear arrangement, and the middle part of the long connecting rod is rotatably connected to the support base.

[0008] Furthermore, the support base and the long connecting rod are provided on both sides of the placement tray. An extension plate is fixed to the middle of the long connecting rod facing the placement tray. The switching component one also includes a multi-functional rod. The multi-functional rod is rotatably connected between the extension plates of the two long connecting rods. When the two placement trays connected to the switching component one are arranged in an inclined collinear state, the multi-functional rod is used as a transition support for the bamboo leaf basket between the two placement trays. When the two placement trays connected to the switching component one are parallel to each other, the multi-functional rod is used as a stop bar between the two placement trays on the same layer.

[0009] Furthermore, the second switching component includes a long connecting rod and a support base with the same structure as the first switching component, and the long connecting rod in the second switching component is broken on one side of the extension plate, while the other side remains intact and is hinged to the bottom adapter block of the placement plate.

[0010] Furthermore, the synchronization component includes: two bevel gears, each rotatably mounted on the support bases of the switching component and the switching component, the first bevel gear being coaxially connected to the rotating shaft of the long connecting rod rotatably mounted on the support base; a synchronization shaft, vertically positioned between the switching component and the switching component, supported by a support ring on the outer frame moving bracket; and two bevel gears, coaxially connected to the synchronization shaft, the two second bevel gears rotating synchronously in the same direction, each second bevel gear meshing with one of the two first bevel gears.

[0011] Furthermore, the drive assembly includes: a drive shaft, horizontally rotatably mounted at the bottom of the outer frame movable frame, with one end located outside the outer frame movable frame and equipped with a handwheel, and the other end located below the synchronous shaft; a bevel gear three, coaxially connected to the bottom of the synchronous shaft and close to the drive shaft; a bevel gear four, coaxially connected to the end of the drive shaft away from the handwheel and meshing with the bevel gear three; and a shaft locking device, fixedly mounted on the outer frame movable frame and close to the handwheel, with the drive shaft passing through the shaft locking device, which is used to lock the drive shaft.

[0012] Furthermore, the placement tray includes two parallel side rods and a plurality of rolling rollers rotatably connected between the two side rods, wherein the rolling surface of the rolling rollers is lower than the upper surface of the side rods.

[0013] Furthermore, each of the two placement trays on the same layer has a swing rod above its far ends. The swing rod is hinged to the outer frame moving frame and prevents the bamboo leaf baskets on the placement trays from moving out of the outer frame moving frame.

[0014] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0015] 1. Due to the adoption of a mechanical switching mode, during loading and unloading operations, turning the handwheel drives the synchronous shaft to rotate through the bevel gear set. The synchronous shaft drives the long connecting rods on both sides to swing synchronously through the bevel gear set, and the placement tray changes from a horizontal state to an inclined collinear state, forming a continuous slide. The multi-functional rod automatically adjusts to a transition support state, allowing workers to easily push and pull the bamboo leaf baskets to complete loading and unloading. Workers do not need to repeatedly lift the heavy bamboo leaf baskets, reducing labor intensity and improving the transportation efficiency of bamboo leaves. In addition, the double-row, double-layer design greatly increases the single transport capacity and matches the drying box.

[0016] 2: Since the switching component 1 is equipped with a multi-functional rod, the multi-functional rod of the two placement trays connected to the switching component 1 in the inclined collinear arrangement is used as a transition support for the bamboo leaf basket between the two placement trays. The multi-functional rod of the two placement trays connected to the switching component 1 in the parallel state is used as a stop bar between the two placement trays on the same layer.

Detailed Implementation

[0024] To better understand the technical solution of this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1 and Figure 2A raw material conveying mechanism for processing bamboo leaves includes an outer frame moving frame 1, a placement tray 2, a switching component 1 3, a switching component 2 4, a synchronization component 5, and a drive component 6. The outer frame moving frame 1, serving as the basic frame of the entire mechanism, is welded from high-strength steel to ensure load-bearing capacity. The bottom of the outer frame moving frame 1 is equipped with casters 102 with brakes for easy manual pushing or mechanical traction. The placement tray 2 is used to place bamboo leaf baskets and is arranged in a double row and double layer within the outer frame moving frame 1. Each placement tray 2 consists of two parallel side rods 21 and several rolling rollers 22. The rolling rollers 22 are rotatably connected between the two side rods 21, with their rolling surface slightly lower than the upper surface of the side rods 21, allowing the bamboo leaf baskets to slide smoothly without shifting or falling off. Thus, workers can place the bamboo leaf baskets from the end of the placement tray 2 and then use the rolling rollers 22 to easily push the baskets into the placement tray 2.

[0026] Continue to refer to Figure 1 and Figure 2 The four placement trays 2 in a double-row, double-layer configuration are installed in the outer frame movable bracket 1 as follows: the two upper placement trays 2 with their far ends hinged to the outer frame movable bracket 1, while their near ends can swing freely; one of the two lower placement trays 2 is fixed to the outer frame movable bracket 1 and cannot move horizontally, while the other is hinged to the placement tray 2 directly above it in the same way, with one end fixed and the other end swinging. (See also...) Figure 3 and Figure 4 As shown, slide rails 201 are mounted on the lower surfaces of the side rods 21 on both sides of the swingable placement tray 2, and the slide rails 201 are close to the swingable end of the placement tray 2. A slider 202 is slidably connected to the slide rails 201, and an adapter block 203 is fixedly connected to the slider 202. The adapter block 203 is used to hinge with the switching component. In addition, refer to Figure 1 As shown, a swing rod 101 is provided above the far ends of the two placement trays 2 on the same layer. The swing rod 101 is hinged to the outer frame movable frame 1 and can be manually flipped up or down to prevent the bamboo leaf basket from sliding out during transportation.

[0027] Reference Figure 2 and Figure 3The switching component 3 is used to control the switching between the two obliquely hinged placement trays 2 on the upper and lower layers in a parallel state (transportation mode) and an inclined collinear state (loading and unloading mode). The switching component 3 includes a long connecting rod 31, a support base 32, and a multi-functional rod 33. Two long connecting rods 31 are provided and located on both sides of the length of the placement tray 2. The two ends of the long connecting rods 31 are respectively hinged to the transition blocks 203 at the bottom of the two inclined upper and lower placement trays 2. An extension plate 311 is fixed to the middle of the long connecting rods 31 facing the placement tray 2. The support base 32 is fixed to the outer frame moving frame 1 and is located in the gap between the two inclined upper and lower placement trays 2. The middle of the long connecting rods 31 is rotatably connected to the support base 32, and the axis of rotation is horizontal. The multi-functional rod 33 is rotatably connected between the extension plates 311 of the two long connecting rods 31. The multi-functional rod 33, which is connected to the switching component 3, is used as a transition support for the bamboo leaf basket between the two placement trays 2 in an inclined collinear arrangement. Figure 1 and Figure 2 The multi-functional lever 33, which connects to the switching component 3 and is in a parallel state with the two placement trays 2, serves as a stop between the two placement trays 2 on the same layer (e.g., Figure 5 and Figure 6 ).

[0028] Reference Figure 2 The second switching component 4 includes a long connecting rod 31 and a support base 32 with the same structure as the first switching component 3. However, the second switching component 4 is only connected to the upper placement plate 2 that is not connected to the first switching component 3, ensuring that the two swingable placement plates 2 in the same row move synchronously. The long connecting rod 31 in the second switching component 4 is disconnected on one side of the extension plate 311, while the other side remains intact and is hinged to the adapter block 203.

[0029] Continue to refer to Figure 2 The synchronization component 5 is used to ensure that the switching component 3 and the switching component 4 move synchronously. The synchronization component 5 includes a first bevel gear 51, a synchronization shaft 52, and a second bevel gear 53. There are two first bevel gears 51, which are fixed to the rotating shafts of the long connecting rods 31 of the switching component 3 and the switching component 4, respectively. The synchronization shaft 52 is installed vertically and fixed to the outer frame moving frame 1 by a support ring 100. There are two second bevel gears 53, which are coaxially connected to the synchronization shaft 52. The two second bevel gears 53 mesh with the two first bevel gears 51, respectively, to ensure synchronous rotation.

[0030] Continue to refer to Figure 1 and Figure 2The drive assembly 6 provides power and controls the operation of the switching assembly. The drive assembly 6 includes a drive shaft 61, a third bevel gear 62, a fourth bevel gear 63, and a shaft locking device 64. The drive shaft 61 is horizontally mounted at the bottom of the outer frame moving bracket 1. One end extends out and is fitted with a handwheel 601 for easy manual operation. The other end is coaxially connected to the fourth bevel gear 63. The third bevel gear 62 is fixed to the bottom of the synchronous shaft 52 and meshes with the fourth bevel gear 63 to convert horizontal rotation into vertical rotation. The shaft locking device 64 is installed at the end of the drive shaft 61 near the handwheel 601 to lock the drive shaft 61 and prevent the placement plate 2 from swinging accidentally.

[0031] The functional principle of this application can be explained through the following methods:

[0032] When loading the bamboo leaf baskets, the worker opens the shaft locking device 64 and turns the handwheel 601. The handwheel 601 drives the drive shaft 61 to rotate, which in turn drives the bevel gear 4 63 to rotate. The bevel gear 4 63 drives the bevel gear 3 62 to rotate, which in turn drives the synchronous shaft 52 to rotate. The synchronous shaft 52 drives the two bevel gears 2 53 to rotate, and the two bevel gears 2 53 drive their respective bevel gears 1 51 to rotate. This causes the switching assembly 1 3 and the switching assembly 2 4 to operate synchronously. The long connecting rod 31 in the switching assembly 1 3 and the switching assembly 2 4 swings, and the two placement trays 2 of the upper and lower layers, which are inclined and hinged to the outer frame moving frame 1, are eventually arranged in an inclined collinear arrangement. The placement tray 2 of the upper layer that is not connected to the switching assembly 1 3 swings synchronously with the placement tray 2 directly below it, and eventually also becomes inclined. At this time, the raw material conveying mechanism for bamboo leaf processing is in loading and unloading mode.

[0033] Therefore, the worker can first place the bamboo leaf basket onto the lower inclined placement tray 2, then push the bamboo leaf basket diagonally upwards onto the upper inclined placement tray 2. Afterwards, rotate the handwheel 601 in the opposite direction to adjust the raw material conveying mechanism for leaf processing to transport mode. At this time, the bamboo leaf basket can be pushed onto the placement tray 2 connected to the switching component 2 4. Then, a crossbar can be inserted through the outer frame moving frame 1 to prevent the bamboo leaf basket on the upper placement tray 2 from moving. Afterwards, adjust to the loading and unloading mode, and then... The leaf baskets are pushed onto the upward-sloping placement trays 2, and then the system is switched to transport mode. At this time, both upper placement trays 2 are loaded with leaf baskets, and the lower two placement trays 2 are horizontal. The leaf baskets can be pushed onto the lower two placement trays 2 at both ends of the outer frame moving frame 1. Thus, through mechanical switching mode, workers do not need to repeatedly lift heavy leaf baskets, and the double-row, double-layer design greatly increases the single transport capacity. When matched with the drying box, it reduces labor intensity and improves the transport efficiency of leaf baskets.

[0034] In addition, when removing the bamboo leaf baskets from the placement tray 2, first remove the bamboo leaf baskets from the lower placement tray 2, and then adjust to the loading and unloading mode. At this time, the upper placement tray 2 will not damage the bamboo leaves inside the bamboo leaf baskets during the tilting process due to the bamboo leaf baskets in the lower layer.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
