Description

Technical Field

[0001] This application relates to the field of medicinal material sorting and feeding technology, specifically to a feeding device for sorting medicinal materials in traditional Chinese medicine processing. Background Technology

[0002] In the sorting stage of traditional Chinese medicine (TCM) processing, the performance of the feeding device plays a crucial role in sorting efficiency and the quality of the herbs. However, existing feeding devices for TCM herb sorting have several shortcomings. First, many traditional feeding devices cannot effectively prevent the accumulation and adhesion of herbs during the feeding process, resulting in uneven delivery of herbs to the sorting stage and severely impacting sorting efficiency and accuracy. Second, during transport, herbs often become suspended or blocked due to friction and interaction forces, leading to poor transport and requiring manual intervention to clear blockages, increasing labor intensity and time costs. Third, the conveying path design of traditional feeding devices is often unreasonable; herbs may break due to excessive impact when reaching the conveying mechanism, producing a large number of fragments or debris, which not only reduces the quality of the herbs but also makes subsequent sorting difficult. Furthermore, existing feeding devices often lack precise and convenient adjustment of the feeding speed, failing to adapt to the needs of different types of herbs or different sorting processes. Simultaneously, some feeding devices have low levels of automation, relying heavily on manual operation, resulting in low work efficiency. Finally, some devices experience difficulty in resetting during the reciprocating motion of components, which affects the stable operation of the device.

[0003] Therefore, developing a feeding device for sorting Chinese medicinal materials in Chinese medicine processing that can solve the above problems and achieve uniform feeding, smooth conveying, precise speed adjustment, automated operation, and stable and reliable operation is of great practical significance.

The vibration block is located outside the upper conveying hopper where the contact rod is located, and the vibration block is fixedly connected to the contact rod. The other end of the storage spring is fixedly connected to the upper conveying hopper.

[0007] The middle layer control box is equipped with an adjustment assembly, which includes a partition plate, a guide plate, and an adjustment plate. The partition plate is fixedly installed at the discharge port of the middle layer control box, the guide plate is fixedly installed at the inlet of the middle layer control box, and the adjustment plate is rotatably connected to the guide plate.

[0008] Preferably, the feeding assembly has a Z-shaped structure, and the conveying speed of the medicinal materials is reduced by changing the direction of movement through two bends.

[0009] Preferably, an inner support rod is fixedly installed on the lower conveying hopper, and multiple arc-shaped blocks are fixedly installed on the inner support rod. The end of the contact rod near the inner support rod contacts the inner support rod.

[0010] Preferably, an adjustment shaft is fixedly installed on the adjustment plate, the adjustment shaft is rotatably connected to the middle layer control box, a rotating handle is fixedly installed at both ends of the adjustment shaft, a ratchet is fixedly installed on the adjustment shaft, a limit rod is slidably installed on the slide groove of the middle layer control box, a pawl is rotatably installed on the shaft of the limit rod, a torsion spring is installed on the shaft of the limit rod, the torsion spring is fixedly connected to the pawl, and the pawl engages with the ratchet.

[0011] Preferably, a return spring and a mounting bracket are sleeved on the adjusting shaft, the mounting bracket is fixedly connected to the middle layer control box, and the two ends of the return spring are fixedly connected to the handle and the mounting bracket, respectively.

[0012] Preferably, the left slide rod is provided with a transmission assembly, which includes a lower transmission rod, a lower rotating shaft, an intermediate transmission rod, an upper rotating shaft, and an upper transmission rod. A drive shaft is rotatably mounted on the support frame. The drive shaft is fixedly connected to one end of the lower transmission rod.

[0013] Preferably, a push-pull ring is fixedly installed on the left slide rod, and a buffer spring is sleeved on the left slide rod. The buffer spring is fixedly connected to the push-pull ring and the left support rod at its two ends, respectively.

[0014] The technical solution provided in this application has the following advantages compared with the prior art:

[0015] 1. This application utilizes the rotation of the feeding tray, the coordination of the adjusting plate and the partition plate in the middle control box, and the lateral reciprocating movement of the lower conveying hopper to disperse the medicinal materials, preventing them from sticking together and piling up, ensuring uniform distribution, and laying the foundation for subsequent efficient sorting. For example, the partition plate can separate and impact the piled-up medicinal materials, allowing them to be conveyed through different gaps and achieve distribution and diffusion.

[0016] 2. The rotating connection between the adjusting plate and the guide plate and the ratchet mechanism of this application can precisely control the gap between the adjusting plate and the bottom surface of the middle control box, thereby precisely controlling the feeding speed of medicinal materials and meeting different sorting needs.

[0017] 3. When the lower conveying hopper of this application moves back and forth, the contact rod is pushed by the arc block to stretch the storage spring. When the arc block leaves, the storage spring drives the vibrating block to strike the outer wall of the upper conveying hopper, so that the medicinal materials in the upper conveying hopper and the middle control box are dispersed, preventing suspension and blockage caused by friction and other factors, and ensuring smooth conveying.

[0018] The lateral reciprocating movement of the lower conveying hopper in this application not only drives the vibration component to work, but also further laterally shakes and disperses the medicinal materials in the hopper, further avoiding the accumulation of medicinal materials and ensuring that the medicinal materials always maintain a good dispersed state during the conveying process.

[0019] 4. The feeding component of this application adopts a Z-shaped structure, which increases the movement path of medicinal materials by changing the conveying direction, reduces the impact force when the medicinal materials are conveyed to the conveying mechanism, reduces the breakage of medicinal materials and the generation of fragments or debris, ensures the quality of medicinal materials, and improves the quality of sorted products.

[0020] 5. The adjustment plate of this application is adjusted in angle by adjusting shaft and handle. With ratchet, pawl and return spring, it can not only adjust the feeding speed of medicinal materials, but also fix the angle after adjustment and can be easily reset. The operation is simple and flexible. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] like Figures 1 to 7As shown, a feeding device for sorting Chinese medicinal materials in traditional Chinese medicine processing includes a support frame 101. A feeding assembly and a conveying mechanism 102 are mounted on the support frame 101. The feeding assembly includes a discharge tray 103, an upper conveying hopper 104, a middle control box 105, and a lower conveying hopper 106. The discharge tray 103 and the upper conveying hopper 104 are fixedly mounted on the support frame 101. The inlet of the middle control box 105 is fixedly connected to the outlet of the upper conveying hopper 104. The discharge port of the box 105 is slidably connected to the inlet of the lower conveying hopper 106. A right support rod 118 and a buffer spring 116 are fixedly installed on the support frame 101. A left slide rod 114 and a right slide rod 119 are fixedly installed on the lower conveying hopper 106. Slide grooves are provided on the left slide rod 114 and the right slide rod 119. The left slide rod 114 is slidably connected to the push-pull ring 117, and the right slide rod 119 is slidably connected to the right support rod 118. A transmission component is provided on the left slide rod 114.

[0032] The upper conveying hopper 104 is equipped with a vibration assembly, which includes a contact rod 122, a vibration block 124, and a storage spring 123. The contact rod 122 is slidably connected to the upper conveying hopper 104, and the storage spring 123 is sleeved on the contact rod 122. One end of the storage spring 123 away from the upper conveying hopper 104 is fixedly connected to the other end of the contact rod 122 away from the upper conveying hopper 104. The vibration block 124 is located outside the contact rod 122 at the upper conveying hopper 104, and the vibration block 124 is fixedly connected to the contact rod 122. The other end of the storage spring 123 is fixedly connected to the upper conveying hopper 104.

[0033] An adjustment assembly is provided on the middle layer control box 105. The adjustment assembly includes a partition plate 125, a guide plate 126 and an adjustment plate 127. The partition plate 125 is fixedly installed at the discharge port of the middle layer control box 105, the guide plate 126 is fixedly installed at the inlet of the middle layer control box 105, and the adjustment plate 127 is rotatably connected to the guide plate 126.

[0034] Specifically, during the sorting of medicinal materials, the feeding of medicinal materials is controlled by the feeding component to disperse the medicinal materials and control the conveying speed of the medicinal materials. The medicinal materials can fall evenly and stably onto the conveying mechanism 102, which facilitates the subsequent sorting of medicinal materials and avoids some medicinal materials sticking together and piling up, thus affecting the sorting efficiency.

[0035] During feeding, the medicinal materials are placed on the feeding tray 103. The feeding tray 103 is equipped with a rotating structure, allowing it to rotate around the point of contact with the upper conveying hopper 104. The direction of rotation is limited to the upper conveying hopper 104 towards the middle control box 105, i.e. Figure 3In the indicated state, the feeding tray 103 rotates counterclockwise; through the rotation of the feeding tray 103, the medicinal materials slide into the upper conveying hopper 104. The upper conveying hopper 104 is provided with an inclined surface, so that the medicinal materials inside the upper conveying hopper 104 slide along the inclined surface into the middle control box 105. Then, the guide plate 126 and the adjusting plate 127 on the middle control box 105 block and restrict the movement of the medicinal materials in the middle control box 105 towards the lower conveying hopper 106. Thus, by controlling the rotation angle of the adjusting plate 127 on the guide plate 126, the gap between the adjusting plate 127 and the bottom surface of the middle control box 105 is changed, thereby controlling the speed at which the medicinal materials are output through this gap, that is, the speed of feeding the medicinal materials.

[0036] After the medicinal materials pass through the gap between the adjusting plate 127 and the bottom surface of the middle control box 105, they come into contact with multiple partition plates 125. The evenly arranged partition plates 125 separate and impact the medicinal materials, causing the materials piled up in one place to disperse. They are then transported through the gaps between different partition plates 125. This prevents the accumulation of medicinal materials in one place, where the channel formed by the partition plate 125 can only transport a portion of the medicinal materials, and the transport speed is limited. The medicinal materials that do not pass through can be moved to the channels formed by other partition plates 125 by the action of the vibration mechanism, thereby achieving the diffusion of the medicinal material transport distribution. This helps to keep the medicinal materials as evenly distributed as possible when they are piled up in one place, which is convenient for subsequent sorting.

[0037] During feeding, the lower conveying hopper 106 is controlled to slide rapidly back and forth laterally at the discharge port of the middle control box 105. This causes the arc-shaped block 121 on the inner support rod 120 inside the lower conveying hopper 106 to contact the end of the contact rod 122 near the inner support rod 120. The arc-shaped surface of the arc-shaped block 121 then pushes the contact rod 122 to slide on the guide plate 126 and the upper conveying hopper 104. Figure 4As shown, under the rapid push of the arc-shaped block 121, the contact rod 122 slides away from the inner support rod 120, thereby pushing one end of the storage spring 123 at the rear end of the contact rod 122. Because the other end of the storage spring 123 is fixedly connected to the outer wall of the upper conveying hopper 104, the storage spring 123 is stretched. As the contact rod 122 moves, it also drives the vibrating block 124 away from the upper conveying hopper 104. When the arc-shaped block 121 on the inner support rod 120 quickly moves away from the contact rod 122, the contact rod 122 instantly loses its thrust, thus... Under the action of the energy storage spring 123, the drive contact rod 122 is quickly reset, and the vibration block 124 on the contact rod 122 quickly approaches the outer wall of the upper conveying hopper 104, eventually knocking on the outer wall of the upper conveying hopper 104, thereby causing the upper conveying hopper 104 to vibrate. The upper conveying hopper 104 and the middle control box 105 shake the medicinal materials inside, so that when the internal materials are suspended or blocked due to friction and interaction forces, they are dispersed and can continue to move, ensuring smooth conveying.

[0038] When the medicinal materials enter the lower conveying hopper 106, the lateral reciprocating movement of the lower conveying hopper 106 is controlled to rapidly shake the materials laterally, further dispersing them and ensuring uniform distribution to prevent accumulation. During the reciprocating movement of the lower conveying hopper 106, at the point of contact with the middle control box 105, the lower conveying hopper 106 slides outside the middle control box 105. The left and right sliding rods 114 and 119 are fixedly connected to the sides of the lower conveying hopper 106, respectively. Lateral sliding is achieved through the cooperation of the sliding grooves and sliders of the left and right sliding rods 114 and 119 with the left and right support rods 115 and 118.

[0039] like Figure 3 As shown, the feeding assembly has a Z-shaped structure, and the conveying speed of the medicinal materials is reduced by changing the direction of movement through two bends.

[0040] Specifically, by changing the conveying direction on both sides, the movement path of the medicinal materials is increased, thereby improving the feeding time of the medicinal materials and reducing the impact force when the medicinal materials are conveyed to the conveying mechanism 102. This avoids the medicinal materials from breaking and generating more fragments or debris when they are directly conveyed to the conveying mechanism 102 on a relatively steep path, which would affect sorting and product quality.

[0041] like Figure 4 and Figure 6 As shown, an inner support rod 120 is fixedly installed on the lower conveying hopper 106, and a plurality of arc-shaped blocks 121 are fixedly installed on the inner support rod 120. The end of the contact rod 122 near the inner support rod 120 contacts the inner support rod 120.

[0042] Specifically, the inner support rod 120 is installed on the lower hopper 106 near the middle control box 105, and the arc-shaped block 121 on the inner support rod 120 contacts the discharge port of the middle control box 105. When the arc-shaped block 121 pushes the contact rod 122, the contact rod 122 contacts the inner support rod 120 under the action of the storage spring 123. The contact rod 122, the guide plate 126 and the vibrating block 124 form a set of vibration components. Four sets of vibration components are provided on the upper hopper 104, and four corresponding arc-shaped blocks 121 are also provided on the inner support rod 120. Thus, the four evenly arranged vibration components and the arc-shaped blocks 121 achieve sufficient and uniform vibration of the medicinal materials on the upper hopper 104 and the middle control box 105, ensuring the smooth flow of the internal medicinal materials.

[0043] like Figure 4 and Figure 5 As shown, an adjustment shaft 128 is fixedly installed on the adjustment plate 127. The adjustment shaft 128 is rotatably connected to the middle layer control box 105. Rotary handles 129 are fixedly installed at both ends of the adjustment shaft 128. A ratchet 132 is fixedly installed on the adjustment shaft 128. A limit rod 133 is slidably installed on the slide groove of the middle layer control box 105. A pawl 134 is rotatably installed on the shaft of the limit rod 133. A torsion spring is installed on the shaft of the limit rod 133. The torsion spring is fixedly connected to the pawl 134. The pawl 134 engages with the ratchet 132.

[0044] Specifically, guide plate 126 and adjusting plate 127 are provided with matching grooves. The grooves of guide plate 126 and adjusting plate 127 are misaligned to achieve misaligned installation. Adjusting shaft 128 passes through the holes of adjusting plate 127 and guide plate 126, thereby enabling the rotating installation of adjusting plate 127 and guide plate 126. When it is necessary to adjust the angle between adjusting plate 127 and guide plate 126, that is, the gap distance between adjusting plate 127 and bottom surface of middle layer control box 105, the operator manually controls the rotating handle 129 to rotate. The rotating handle 129 drives the adjusting shaft 128 to rotate on middle layer control box 105. Through the fixed connection between adjusting shaft 128 and adjusting plate 127, adjusting plate 127 is rotated by the corresponding angle, thereby achieving angle adjustment.

[0045] When the adjusting shaft 128 rotates, it drives the ratchet 132 to rotate. The ratchet 132 and the pawl 134 form a ratchet engagement. That is, when the adjusting shaft 128 rotates, it drives the ratchet 132 to rotate. The ratchet 132 drives the pawl 134 to rotate on the shaft of the limiting rod 133 and twists the torsion spring. Through the action of the torsion spring, the pawl 134 is kept in contact with the ratchet 132. When the adjusting shaft 128 rotates to a certain angle, the pawl 134 restricts the ratchet 132, fixing the position of the adjusting shaft 128 and the pawl 134 after rotation and preventing them from resetting. Thus, the angle of the adjusting plate 127 is fixed after adjustment.

[0046] like Figure 5 As shown, a return spring 130 and a mounting bracket 131 are sleeved on the adjusting shaft 128. The mounting bracket 131 is fixedly connected to the middle layer control box 105. The two ends of the return spring 130 are fixedly connected to the rotating handle 129 and the mounting bracket 131, respectively.

[0047] Specifically, when the handle 129 rotates, it drives the return spring 130 to twist. When the angle of the adjustment plate 127 needs to be reset, the control limit rod 133 slides away from the ratchet 132 on the middle control box 105. As a result, the pawl 134 disengages from the ratchet 132 and no longer prevents the ratchet 132 and the adjustment shaft 128 from rotating in the opposite direction. Then, under the action of the return spring 130, the handle 129, the adjustment shaft 128 and the adjustment plate 127 are reset.

[0048] like Figure 6 and Figure 7 As shown, a transmission assembly is provided on the left slide rod 114. The transmission assembly includes a lower transmission rod 109, a lower rotating shaft 110, an intermediate transmission rod 111, an upper rotating shaft 112, and an upper transmission rod 113. A drive shaft 108 is rotatably mounted on the support frame 101. The drive shaft 108 is fixedly connected to one end of the lower transmission rod 109. Both the lower rotating shaft 110 and the upper rotating shaft 112 include a rotating shaft portion and a connecting portion. The other end of the lower transmission rod 109 is rotatably connected to the rotating shaft portion of the lower rotating shaft 110. The intermediate transmission rod 111 is rotatably connected to the connecting portions of the lower rotating shaft 110 and the upper rotating shaft 112, respectively. The rotating shaft portion of the upper rotating shaft 112 is rotatably connected to one end of the upper transmission rod 113. The other end of the upper transmission rod 113 is fixedly connected to the left slide rod 114.

[0049] Specifically, during sorting, the motor 107 is started by the electronic control system, and the conveyor mechanism 102 is driven by the belt and belt conveyor to move the medicinal materials and drive the drive shaft 108 to rotate. The transmission component on the drive shaft 108 drives the left slide bar 114 to move laterally back and forth quickly on the left support rod 115, thereby realizing the lateral rapid back and forth movement of the lower conveying hopper 106 on the middle control box 105.

[0050] like Figure 7As shown, when the drive shaft 108 rotates, it drives the lower transmission rod 109 to rotate around the axis of the drive shaft 108. The lower transmission rod 109 drives the lower end of the intermediate transmission rod 111 to rotate around the axis of the drive shaft 108 via the lower rotating shaft 110. At the same time, the lower rotating shaft 110 rotates on the lower transmission rod 109, while the upper end of the intermediate transmission rod 111 pulls the upper transmission rod 113 and its upper rotating shaft 112, causing the intermediate transmission rod 111 to rotate on the lower rotating shaft 110 and the upper rotating shaft 112, while the upper rotating shaft 112 rotates on the upper transmission rod 113. 13 rotates on the left slide rod 114 and pulls the left slide rod 114 towards the direction closer to the lower conveyor hopper 106. Thus, the left slide rod 114 slides on the left support rod 115 and pushes the lower conveyor hopper 106 to slide on the middle control box 105. When the drive shaft 108 rotates to 180 degrees, the lower conveyor hopper 106 moves to the farthest distance. When the drive shaft 108 continues to rotate, it drives the left slide rod 114 to move away from the lower conveyor hopper 106, that is, it drives the lower conveyor hopper 106 to reset, thereby realizing the rapid lateral reciprocating movement of the lower conveyor hopper 106.

[0051] like Figure 6 and Figure 7 As shown, a push-pull ring 117 is fixedly installed on the left slide rod 114, and a buffer spring 116 is sleeved on the left slide rod 114. The buffer spring 116 is fixedly connected to the push-pull ring 117 and the left support rod 115 at its two ends respectively.

[0052] Specifically, when the left slide bar 114 moves toward the lower conveyor hopper 106, the push-pull ring 117 compresses the buffer spring 116, thereby accelerating the reset during the reset process through the elastic force of the push-pull ring 117. This avoids the large rotational resistance of the lower transmission rod 109 located below the drive shaft 108, and facilitates the reset process with the assistance of the push-pull ring 117.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
