In addition, in some examples, the inlet port 11 is disposed at a position distant from the outlet port 12. In other examples, feed port 11 may not be in contact with discharge port 12. Further, in some examples, feed port 11 may be parallel to discharge port 12.

In some examples, the outlet 12 may be larger than the inlet 11. In other examples, the reservoir 10 may gradually expand from the inlet 11 to the outlet 12. Thereby, the passage of material (e.g. viscous material) through the discharge opening 12 can be facilitated.

In some examples, the reservoir 10 may be a hopper. Additionally, in some examples, material may be stored in a hopper and may be output from the hopper discharge 12.

In some examples, the reservoir 10 may also be provided with a cut-off plate (not shown). Specifically, the cutoff plate may be provided at the discharge port 12 of the storage part 10 and used for the cutoff plate discharge port 12. When the material is not needed to be conveyed, the cutting plate is normally closed to keep the material in the storage part 10; when the material needs to be transported, the cutting plate is opened, so that the material is delivered from the discharge hole 12.

In some examples, the feeding portion 20 may include a feeding chute 21, a conveyor, and a feed opening. In addition, in some examples, chute 21 may receive material from spout 12. In other examples, the feed opening may be disposed on the downstream side of the feed chute 21.

In some examples, the storage portion 10 and the delivery portion 20 may be hermetically fixed together. In this case, the scattering of the material in the material conveying process can be reduced, and dust can be prevented from flying.

In some examples, the feed chute 21 may include a U-shaped groove 21 a. In other examples, U-shaped groove 21a may communicate with spout 12. In other words, the notch of the U-shaped groove 21a may be connected with the discharge hole 12. This reduces clogging of the material at the discharge opening 12.

In some examples, the notch of U-shaped slot 21a may be sized to coincide with spout 12. In other examples, the notch of U-shaped slot 21a may not be sized to correspond to spout 12. For example, the notch of U-shaped groove 21a may be slightly smaller or slightly larger than spout 12.

In some examples, the notch of U-shaped groove 21a may be directly connected with spout 12. In other examples, the notch of U-shaped groove 21a may be connected with spout 12 via an extension. Wherein the extension may surround the discharge opening 12.

In some examples, the delivery chute 21 may further include a cylindrical chute 21 b. In addition, in some examples, as shown in fig. 3, the cylindrical groove 21b may be connected with the U-shaped groove 21 a. This enables the material to be conveyed from the U-shaped groove 21a to the cylindrical groove 21 b. In other examples, the side of the cylindrical groove 21b connected to the U-shaped groove 21a may be connected to the storage part 10. In addition, in some examples, the chute 21 may be integrally formed.

In some examples, the feed opening may be provided on the downstream side of the cylindrical groove 21 b. This facilitates the feeding of the material feeding unit 20 to the crushing mechanism 31. Additionally, in some examples, the direction of the feed opening may be opposite to the direction of the discharge opening 12.

Fig. 4 is a partial schematic configuration diagram illustrating the material conveying unit 20 of the material conveying device 1 according to the example of the present invention. Fig. 5 is a schematic structural view showing the helical blade 23 of the delivery unit 20 according to an example of the present invention.

In some examples, the conveyor may include a helical blade 23 and a drive motor 22. In addition, in some examples, as shown in fig. 4, a helical blade 23 may be disposed in the hopper 21. In other words, the helical blade 23 may be disposed in the U-shaped groove 21a and the cylindrical groove 21 b.

In other examples, the helical blade 23 may be driven by the drive motor 22. In other words, the conveyor may be driven by the drive motor 22. Additionally, in some examples, a conveyor may transport material from the U-shaped trough 21a to the cylindrical trough 21 b.

In some examples, the inner diameter of the cylindrical groove 21b may match the outer diameter of the helical blade 23. Also in some examples, the inner diameter of the cylindrical groove 21b may have a suitable tolerance fit with the outer diameter of the helical blade 23. Thereby, the spiral blade 23 can rotate freely in the feed chute 21. That is, the cylindrical groove 21b and the helical blade 23 may have a gap therebetween. In other examples, the outer diameter and pitch of the helical blade 23 may be calculated based on the kind of the material and obtained through testing. In other examples, the helical blades 23 may be angled with respect to the axial direction of rotation.

In some examples, the conveying direction of the material in the conveying chute 21 may be determined by the rotation direction of the spiral blade 23 and the rotation direction of the spiral blade 23. Additionally, in some examples, the direction in which the helical blade 23 rotates may be determined by the drive motor 22.

In some examples, the helical blade 23 may be a left-handed helical blade 23. In this case, when the screw blade 23 rotates counterclockwise as viewed from the side of the drive motor 22, the material is conveyed to the side where the drive motor 22 is located, and when the screw blade 23 rotates clockwise, the material is conveyed to the side away from the side where the drive motor 22 is located.

In some examples, the helical blade 23 may be a right-turn helical blade 23. In this case, when the screw blade 23 rotates clockwise as viewed from the driving motor 22 side, the material is conveyed toward the driving motor 22 side, and when the screw blade 23 rotates counterclockwise, the material is conveyed away from the driving motor 22 side.

In some examples, the conveyor may be a shaftless screw conveyor. In this case, the conveyer does not have spiral center pin, can be favorable to carrying easily winding, stickness's material from this to can reduce the material and block up. In other words, the helical blade 23 may be of a centerless design.

In some examples, the helical blade 23 may be selected based on the type of material. Additionally, in some examples, the helical blades 23 may be made of food grade materials. For example, the helical blade 23 may be made of food grade stainless steel or food grade silicone. In other examples, the helical blade 23 may be made of food grade stainless steel and coated with food grade silicone material.

In some examples, the helical blade 23 may connect both ends of the hopper 21. Specifically, one end of the spiral blade 23 may be connected to a side wall of the U-shaped groove 21a, and the other end may be connected to a side wall of the cylindrical groove 21 b. Additionally, in some examples, the drive motor 22 may be coupled to the helical blade 23. This enables the helical blade 23 to be rotationally driven. In other examples, the driving motor 22 may be disposed outside the cylindrical groove 21 b. In addition, in some examples, the driving motor 22 may be disposed outside the U-shaped groove 21 a.

In some examples, the pitch on the helical blades 23 may be the same. In other examples, the pitch on the helical blade 23 may be different.

In some examples, optionally, in the conveyor, the pitch of the helical blade 23 near the feed opening is smaller than the pitch of the helical blade 23 near the discharge opening 12. Therefore, the material conveying device can be favorable for conveying materials to the feed opening and can also be favorable for blanking at the feed opening.

In some examples, the feed opening may be provided with a flap. Additionally, in some examples, a flapper may be used to adjust the blanking flow rate. In other examples, the feed opening may be connected to a crushing mechanism 31 (described later).

In some examples, as shown in fig. 1, the charging section 30 may include a crushing mechanism 31 and a conveying unit 32. In other examples, the crushing mechanism 31 may receive material from a feed opening. In addition, in some examples, the conveying unit 32 may convey the material after being crushed by the crushing mechanism 31.

In some examples, the crushing mechanism 31 may include a fixed module 312 and a crushing module 313. Additionally, in some examples, the stationary module 312 may include a receiving port 311 and a dispensing port. In other examples, the receiving port 311 may be used to receive material and the feeding port may be used to output material. For example, the receiving opening 311 may receive the material from the feeding opening, and the feeding opening may deliver the material crushed by the crushing mechanism 31 to the conveying unit 32.

In some examples, the securing module 312 may be hermetically connected to the feed opening. Therefore, the material scattering in the blanking process can be reduced. Specifically, the receiving opening 311 of the fixing module 312 may surround the feeding opening and be fixed to the feeding portion 20, or may be aligned with the feeding opening and be fixed to the feeding portion 20. In addition, in some examples, the fixing module 312 may be fixed to the outer surface of the chute 21. In other examples, the fixed module 312 may be connected to the feed opening or the cylindrical groove 21b by soldering.

In some examples, the crushing mechanism 31 may have a servo system. Additionally, in some examples, the servo system may include a servo motor. In other examples, the servo system may include a servo controller.

Fig. 6 is a partial perspective view illustrating a material conveying apparatus 1 according to an example of the present invention.

In some examples, the conveying unit 32 may further include a striker plate for preventing material from being missed sideways during conveyance. In some examples, as shown in fig. 6, the conveying unit 32 may include a first striker plate 322a and a second striker plate 322b disposed at both sides of the conveying unit 32. This can reduce leakage of the material from the conveying unit 32. That is, the conveying unit 32 may include a first striker plate 322a and a second striker plate 322b disposed at both sides of the first conveyor belt. In other words, the conveying unit 32 may include a first striker plate 322a and a second striker plate 322b disposed at both sides of the first belt 321.

In some examples, a material flow detector 33 may be provided in the material conveying path between the crushing mechanism 31 and the conveying unit 32. Additionally, in some examples, the material flow detector 33 may sense whether material is present.

In some examples, the crushing speed of the crushing mechanism 31 may be controlled according to the sensing result of the material flow detector 33. Additionally, in some examples, the material flow detector 33 may sense whether material is present on the conveyor unit 32. In other examples, the material flow detector 33 may sense whether material is present on the first belt 321.

In some examples, the operation of the crushing mechanism 31 may be controlled by the control portion 50 when the material flow detector 33 does not sense the presence of material. Thus, the operation of the crushing mechanism 31 can be controlled by monitoring the material flow rate detector 33. Specifically, if the material flow rate detector 33 does not detect the presence of the material, the control unit 50 feeds back the material to the servo controller, and the servo controller controls the operation of the servo motor.

In some examples, the control portion 50 may be provided with a predetermined pulse time. In addition, in some examples, the control part 50 may regulate the crushing speed of the crushing mechanism 31 to be decreased if the material flow rate detector 33 can continuously detect that the material exists on the conveying unit 32, and the control part 50 may regulate the crushing speed of the crushing mechanism 31 to be increased if the material flow rate detector 33 cannot continuously detect that the material exists on the conveying unit 32 within a predetermined pulse time. In this case, the flow rate of the material from the crushing mechanism 31 to the conveying unit 32 can be controlled by controlling the crushing speed, so that the weight of the material on the conveying unit 32 can be controlled, and further, the accurate control of the weight of the material of the weighing part 40 can be facilitated, whereby the accuracy of the material transporting device can be improved.

In some examples, the control portion 50 may regulate the crushing mechanism 31 to stop crushing if the predetermined pulse time is exceeded and the material flow detector 33 can still continuously detect the presence of material on the conveyor unit 32. In addition, in some examples, after the crushing mechanism 31 is stopped, if no material exists on the conveying unit 32, the control part 50 may regulate the crushing mechanism 31 to start crushing.

In some examples, the control part 50 may regulate the crushing speed to be slowed down if the material flow rate detector 33 can continuously detect the presence of the material on the first belt 321, and the control part 50 may regulate the crushing speed to be accelerated if the material flow rate detector 33 cannot continuously detect the presence of the material on the first belt 321 within a predetermined pulse time.

In some examples, the control portion 50 may regulate the crushing mechanism 31 to stop crushing if the predetermined pulse time is exceeded and the material flow detector 33 can still continuously detect the presence of material on the first belt 321. In addition, in some examples, after the crushing mechanism 31 is stopped, if there is no material on the first belt 321, the control part 50 may regulate the crushing mechanism 31 to start crushing.

In some examples, the control section 50, the servo controller, and the material flow detector 33 may constitute a closed loop control system. Specifically, the material flow rate detector 33 can continuously detect the presence of the material on the first belt 321 within a predetermined pulse time, and can feed back the material to the control portion 50, and then the control portion 50 feeds back the material to the servo controller, and then the servo controller controls the crushing speed of the crushing mechanism 31 by controlling the servo motor. In addition, the control part 50 may regulate the crushing speed of the crushing mechanism 31 through a servo controller.

In some examples, the material flow detector 33 may detect the material flow between the crushing mechanism 31 and the conveying unit 32. Additionally, in some examples, the material flow detector 33 may indirectly detect the material flow in conjunction with a pulse delay of the control 50.

Further, when the crushing speed of the crushing mechanism 31 is slow, the material flow rate decreases, and when the crushing speed of the crushing mechanism 31 is fast, the material flow rate increases. In some examples, the material flow may be controlled by controlling the crushing speed of the crushing mechanism 31. Thereby, the weight of the material on the conveyor unit 32 can be controlled, and further, accurate control of the weight of the material of the weighing part 40 can be facilitated.

Fig. 8 is a schematic perspective view showing a crushing mechanism 31 according to an example of the present invention.

In some examples, the material flow detector 33 may have a transmitting end 33a and a receiving end 33b (see fig. 8). In addition, in some examples, the material flow rate detectors 33 may be disposed on both sides of the first conveyor belt. That is, the material flow rate detectors 33 may be respectively disposed on the striker plates at both sides of the first conveyor belt. For example, as shown in fig. 4, the emitting end 33a may be disposed on the first striker plate 322a, and the receiving end 33b may be disposed on the second striker plate 322 b. In other examples, material flow detector 33 may be an infrared sensor, a pressure transmitter, a photoelectric sensor, a hall sensor, or the like. This makes it possible to select an appropriate sensor according to the use environment.

In some examples, the material flow rate detector 33 may be an infrared sensor disposed at both sides of the first conveyor belt. In some cases, the infrared sensor may include a transmitting end 33a disposed at the first striker plate 322a and a receiving end 33b disposed at the second striker plate 322b, and the infrared sensor may determine whether material is present on the surface of the first belt 321 by detecting the material between the transmitting end 33a and the receiving end 33 b. Specifically, when the material on the first belt 321 blocks the infrared signal transmission between the transmitting end 33a and the receiving end 33b, the receiving end 33b of the infrared sensor cannot detect the infrared signal, and it is determined that the material exists on the first belt 321; when the material on the first belt 321 does not block the infrared signal transmission between the transmitting end 33a and the receiving end 33b, the receiving end 33b of the infrared sensor receives the infrared signal, and it is determined that the material does not exist on the first belt 321. The presence or absence of material on the first belt 321 can thus be conveniently detected based on the infrared sensor.

In some examples, the material flow detector 33 may be disposed on a baffle of the crushing mechanism 31. Additionally, in some examples, the emitting end 33a of the material flow detector 33 may be disposed on the first baffle 316a and the receiving end 33b of the material flow detector 33 may be disposed on the second baffle 316 b. In other examples, the transmitting end 33a and the receiving end 33b of the material flow detector 33 may be disposed at positions away from the third baffle.

In some examples, the weighing section 40 may be used to receive the material being conveyed by the conveyor unit 32 and to sense the weight of the material.

In some examples, the weighing portion 40 may include a weight sensor to weigh the material. When the weight of the material in the weighing unit 40 exceeds a predetermined weight, the control unit 50 may stop the conveyance of the material feeding unit 20 and the material feeding unit 30. This can reduce the possibility of excessive material conveyance. In addition, in some examples, the control section 50 may control the operation of the conveyor by controlling the drive motor 22. In other examples, the control part 50 may control the operation of the first belt 321 by controlling the first belt motor.

In some examples, the weighing part 40 may weigh the material and generate a weight signal, and the weight signal may be fed back to the control part 50, and the control part 50 may regulate the operation of the first belt motor. In other words, the control section 50, the first belt motor and the weight signal may form a closed loop control system. Therefore, the precision of weighing the materials can be improved.

In some examples, the control portion 50 may regulate operation of the first belt motor based on a comparison of the weight signal to a prescribed weight. In addition, in some examples, the control portion 50 may control the driving motor 22 and the first belt motor to be turned off when the weight signal is equal to or exceeds the prescribed weight.

In some examples, the weight sensor may be a photoelectric, hydraulic, electromagnetic, capacitive, pole-deformation, vibratory, gyroscopic, resistive-strain, or the like sensor. This allows sensors to be selected according to the use environment.

In some examples, the weighing section 40 may also include a flat-bottom scale (not shown). In this case, the weighing section 40 can receive the material from the crushing mechanism 31 by the flat-bed scale, and perform weighing and conveying.

In some examples, the weight sensor of the weighing section 40 may also be disposed below the flat-bottom scale. From this, can directly weigh the material that falls into flat bottom balance.

In some examples, the weighing section 40 may further include a second conveyor belt. In this case, the weighing part 40 may convey the material through the second conveyor belt after obtaining the appropriate material.

In some examples, the weighing part 40 may further have a second support plate for supporting the second conveyor belt. The second backup pad can set up the belt inboard at the second conveyer belt to can support the second conveyer belt, avoid the material to pile up on the surface of second conveyer belt because of collapsing of second conveyer belt.

In some examples, the weighing portion 40 may further include a striker plate for preventing material from being missed sideways during conveyance. In some examples, as shown in fig. 8, the weighing part 40 may include third and fourth striker plates 42a and 42b disposed at both sides of the weighing part 40. This can suppress leakage of the material from the weighing unit 40. That is, the weighing part 40 may include third and fourth striker plates 42a and 42b disposed at both sides of the second conveyor belt. In other words, the weighing part 40 may include third and fourth striker plates 42a and 42b disposed at both sides of the second belt 41.

In some examples, the second conveyor belt may include a second drive gear, a second driven gear, and a second belt 41 disposed between the second drive gear and the second driven gear. Through the rotation of second drive gear, can drive the second belt 41 that sets up between second drive gear and second driven gear, realize the conveying of material from this.

In some examples, the weighing section 40 may also include a second belt motor. Additionally, in some examples, the second drive gear may be driven by a second belt motor. Thereby, the second belt 41 between the second drive gear and the second driven gear can be rotated. Specifically, the second belt motor is connected to a second drive gear, and the second drive gear and the second driven gear are connected by a second belt 41. In this case, the second belt motor drives the second driving gear to rotate, thereby driving the second belt 41 and the second driven gear to rotate, and thus enabling the transfer of the material.

In some examples, the control part 50 may be connected with the feeding part 20, the dosing part 30 and the weighing part 40. In addition, in some examples, the crushing speed of the crushing mechanism 31 is controlled according to the flow rate of the material obtained by the material flow rate detector 33. In other examples, the start and stop of the material delivery portion 20 and the material feeding portion 30 may be controlled based on the weight sensed by the weighing portion 40.

In some examples, the control section 50 may be implemented by a programmable logic controller. This can contribute to the automatic dispensing of the conveyor 1.

For example, the first type crushing blades 3122a may be disposed on the first crushing wall 3121a at a predetermined interval, and the second type crushing blades 3122b may be disposed on the second crushing wall 3121b at a predetermined interval.

In some examples, as shown in fig. 7, the first type of crushing blades 3122a of the first crushing wall 3121a may be configured staggered from the second type of crushing blades 3122b of the second crushing wall 3121 b. In other words, the first type of crushing blades 3122a of the first crushing wall 3121a may correspond to the interval between the second type of crushing blades 3122b, and the second type of crushing blades 3122b of the second crushing wall 3121b may correspond to the interval between the first type of crushing blades 3122 a.

In some examples, a spacer may be disposed between the gears. That is, the spacer may be disposed in the space between the gears. Therefore, the size of the interval of the gears can be controlled by controlling the size of the spacer. For example, the spacer may be disposed within a predetermined spacing between the gears.

In some examples, the thickness of the spacer may be approximately the same. In other examples, the width of the spacer may match the spacing between the gears. For example, the spacer may have a thickness that is approximately the same size as the spacing between the gears, or the spacer may have a thickness that is slightly less than the spacing between the gears. The spacer can thus be arranged exactly between the gears. For example, the thickness of the spacer may be approximately the same as the predetermined spacing between the gears. Additionally, in some examples, the thickness of the spacer may be approximately the same as the tooth width of the gear.

In some examples, the spacers on the roller shafts may each cooperate with a crushing blade on the crushing wall. In other words, the spacers on the roll shafts may correspond to the crushing blades on the crushing wall, respectively. Additionally, in some examples, the thickness of the spacer may match the thickness of the crushing blade. That is, the thickness of the spacer may be approximately the same as the thickness of the crushing blade, or the thickness of the spacer may be slightly greater than the thickness of the crushing blade.

In some examples, the spacer sleeve may cooperate with the crushing blade. In particular, the spacer may correspond to the spacing between the crushing blades. Additionally, in some examples, the spacer may cooperate with the first type of crushing blade 3122a and the second type of crushing blade 3122 b.

In some examples, the clearance between the gear and the crushing wall may be the same as the clearance between the spacer sleeve and the crushing blade. This can improve the consistency of the dosage form of the material crushed by the crushing mechanism 31 and dropped onto the conveyor unit 32. In addition, in some examples, material that is broken into a suitable dosage form may be dropped to the conveyor unit 32 via the space between the gears and the breaking wall, and the space between the spacer and the breaking blade.

In some examples, the clearance between the gear and the spacer may be the same as the clearance between the spacer sleeve and the crushing blade. This can improve the consistency of the dosage form of the material crushed by the crushing mechanism 31 and dropped onto the conveyor unit 32.

In some examples, the gear may be rotated by rotating the roller shaft. In this case, the material in the crushing mechanism 31 can be cut by the rotating gear, and the material in the crushing mechanism 31 can be stirred, whereby the material can be crushed and the material (crushed material) that can pass through the gap between the gear and the spacer and the gap between the spacer and the crushing blade can be thrown down to the conveying unit 32. In other examples, the crushing blade may also cut the material. This can contribute to the crushing of the material.

In some examples, the tooth width of the gear, the thickness of the crushing blade, the spacing between the gear and the spacer, and the spacing between the spacer sleeve and the crushing blade may be related to the dosage form of the material output by the crushing mechanism 31.

In some examples, in the crushing mechanism 31, crushed material may be dropped to the conveyor unit 32 through a gap between the gear and the spacer and a gap between the spacer and the crushing blade. In some examples, to further improve the consistency of the dosage form of the crushed material, it may be preferred that in the crushing mechanism 31, the crushed material can only be thrown to the conveying unit 32 through the gap between the gear and the spacer and the gap between the spacer and the crushing blade.

In some examples, the type of gear is not particularly limited. For example, the gears may be helical gears, conical gears, straight, helical, herringbone, curved, and the like.

In some examples, the gears may have gear holes therethrough in the axial direction. This allows the gear to be attached to the roller shaft.

In some examples, the transmission module 314 may include a drive gear and a driven gear. Thus, the rotation of the roller shaft can be controlled by the driving gear and the driven gear. In some examples, the drive gear may be coupled to a servo motor. Thereby, the drive gear can be driven by the servo motor. Additionally, in some examples, a driven gear may be coupled with the roller shaft. Thus, the roller shaft can rotate synchronously with the driven gear.

In other examples, the transition gear may be smaller than the drive and driven gears.

In some examples, the direction of rotation of the drive gear and the driven gear may be the same and opposite to the direction of rotation of the transition gear. For example, the drive gear and the driven gear may rotate in a clockwise direction, while the transition gear may rotate in a counterclockwise direction.

In some examples, the transmission module 314 may be driven by a servo system. In other examples, the roller shafts may be driven by a servo system, and the control part 50 may control the crushing speed of the crushing mechanism 31 by controlling the servo system. Thereby, the amount of crushed material dropped onto the conveying unit 32 can be accurately controlled. In addition, the crushing speed of the crushing mechanism 31 may be determined by the running speed of the roll shaft running.

In some examples, a servo motor may be used to drive the rotation of the transmission module 314. Additionally, in some examples, a servo motor may drive the roller shafts to rotate via the transmission module 314. In other examples, the servo controller may control the speed of operation of the servo motor. The control unit 50 may control the operation speed of the servo motor by a servo controller.

In some examples, as shown in fig. 10 and 12, the first-type toothed wheel 3132a is configured to be offset from the second-type toothed wheel 3132 b.

In some examples, for viscous materials, materials with dosage forms greater than 20mm, or materials with dosage weights, they may be crushed using crushing mechanism 31.

In some examples, the first roller 3131a and the second roller 3131b may be soft rollers, in other words, the crushing mechanism 31 may have a first soft roller and a second soft roller. In this case, the material (such as the herbal pieces 2) can be kept in the original form, and the surface of the roller can be attached. Therefore, the traditional identification characteristics of the traditional Chinese medicine decoction pieces 2 can be kept, and the subsequent rechecking work can be simply and quickly carried out.

In some examples, when the material passes between the first soft roller and the second soft roller, the material may be sandwiched between the flexible layers of the first soft roller and the second soft roller, and the first soft roller and the second soft roller around the material may still be in contact, thereby effectively controlling the material to be conveyed between the first soft roller and the second soft roller.

In some examples, the sum of the thickness of the flexible layer of the first soft roller and the thickness of the flexible layer of the second soft roller may be at least greater than the size of the material. Therefore, the material can be allowed to pass through between the first soft roller shaft and the second soft roller shaft. In this case, the conveying of the material (such as the herbal pieces 2) between the first soft roller and the second soft roller can be further effectively controlled.

In some examples, a gap may exist between the first soft roller and the second soft roller. That is, the flexible layer of the first flexible roller shaft and the flexible layer of the second flexible roller shaft may not be in contact, that is, a gap may exist between the flexible layer of the first flexible roller shaft and the flexible layer of the second flexible roller shaft. Thereby, the transport of larger material can be controlled.

In some examples, the flexible layer may be one or more of rubber, fabric, or plastic. Therefore, damage to the traditional Chinese medicine decoction pieces 2 can be reduced in the process of conveying the traditional Chinese medicine decoction pieces 2.
