Description

Technical Field

[0001] The present invention relates to a Chinese herbal medicine piece conveying technology, and in particular to a Chinese herbal medicine piece feeding system and method. Background Art

[0002] Decoction pieces refer to Chinese herbal medicines that have been processed and prepared for use in prescriptions or can be used directly in TCM clinics. Decoction pieces are the essence of Traditional Chinese Medicine. The properties and efficacy of herbs altered through different processing methods are a hallmark and advantage of TCM.

[0003] After the slices of Chinese herbal medicine are sliced, they generally need to be dried, sorted and packaged. When different processes are carried out, they need to be loaded through a loading system, and the more common loading equipment is a lifting conveyor belt. When loading the slices, the existing lifting conveyor belt mainly limits the downward movement of the slices through the multiple dry retaining bars arranged at intervals on its surface, so that the loading process of the slices can be carried out smoothly. However, the retaining bars on the lifting conveyor belt are commonly installed in the following ways: the bottom hard base plate is connected and fixed to the surface of the conveyor belt by bolts or the like, or connected by glue adhesion. In the above connection method, when the retaining bar moves to the end transmission roller position, due to the arc-shaped surface of the transmission roller and the close fit between the conveyor belt and the surface of the transmission roller, a gap is likely to appear at the connection between the conveyor belt and the retaining bar. Over time, the gap will gradually increase, which will lead to the situation that the material is easily stuck during the unloading process, resulting in the residue of the slices, causing the slices that have deteriorated to fall into the normal process, increasing safety hazards. Summary of the Invention

[0004] The object of the present invention is to provide a feeding system and method for Chinese herbal medicine slices to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a feeding system for Chinese herbal medicine slices, comprising a conveyor body and a conveyor belt supported and driven by two sets of upper and lower rollers, the rollers being driven by a motor, a plurality of baffles being equidistantly arranged on the conveyor belt, a lower hopper being provided at the bottom of the upper surface of the conveyor body, the width of the conveyor belt being greater than the length of the rollers, corresponding thread grooves being provided on both sides of the surface of the conveyor belt and on both sides of the bottom of the baffles, and locking bolts being threadedly connected to the inner side surfaces of the thread grooves;

[0009] Furthermore, the end of the curtain away from the winding roller passes upward from the bottom of the guide frame and is fixedly connected to the surface of the barrier strip, and the distance between the bottom end of the guide frame and the surface of the conveyor belt is greater than the distance between the slot and the surface of the conveyor belt.

[0010] Furthermore, the position and specifications of the arc cover are adapted to the round tube, and one side of the arc cover abuts against the surface of the conveyor belt, while the other side of the arc cover presses a part of the curtain tightly against the surface of the conveyor belt.

[0011] Furthermore, a plurality of embedding grooves corresponding to the baffles are provided on the surface of the conveyor belt, and an inner embedding strip adapted to the embedding grooves is fixedly connected to the bottom surface of the baffle.

[0012] The present invention also provides a method for feeding Chinese herbal medicine slices, which uses the above-mentioned Chinese herbal medicine slice feeding system, comprising the following steps:

[0013] S1, drive the roller shaft through the motor, so that the roller shaft drives the conveyor belt to rotate;

[0014] S2, the Chinese herbal medicine pieces to be transported are sent into the lower hopper, so that the Chinese herbal medicine pieces fall from the bottom of the lower hopper onto the conveyor belt;

[0015] S3, through the baffle bar, the Chinese herbal medicine pieces falling on the conveyor belt are restricted from sliding downward, so that the Chinese herbal medicine pieces are transported to the top along with the movement of the baffle bar and the conveyor belt;

[0016] S4. Chinese herbal medicine pieces fall from the top of the conveyor belt to the next process position.

[0017] Compared with the prior art, the present invention provides a feeding system and method for Chinese herbal medicine slices, which has the following beneficial effects:

[0018] 1. The feeding system and method of Chinese herbal medicine slices can effectively shield the intersection between the conveyor belt and the conveyor belt during operation through the mutual cooperation between the circular tube, the slot, the winding roller, the curtain, and the first torsion spring.

[0019] 2. The feeding system and method of Chinese herbal medicine slices, through the setting of the arc cover, can make one side of it directly abut against the surface of the conveyor belt, and the other side can press the curtain tightly against the surface of the conveyor belt. In addition, with the cooperation between the second torsion spring, the rotating piece and the positioning column, the contact stability between the cylindrical cover and the conveyor belt can be improved. Therefore, when the conveyor belt is partially bent subsequently, it can still effectively block the gap between the baffle and the conveyor belt and the gap between the subsequent round tube and the arc groove, which can better avoid the residue of Chinese herbal medicine slices.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] See also Figures 1-8 A feeding system for Chinese herbal medicine slices includes a conveyor body 1 and a conveyor belt 102 supported and driven by two sets of upper and lower rollers 101. The rollers 101 are driven by a motor. A plurality of baffles 103 are equidistantly arranged on the conveyor belt 102. A lower hopper 104 is provided at the bottom of the upper surface of the conveyor body 1. The width of the conveyor belt 102 is greater than the length of the rollers 101. Corresponding thread grooves 2 are provided on both sides of the surface of the conveyor belt 102 and on both sides of the bottom of the baffles 103. The inner side of the thread groove 2 is threadedly connected with a locking bolt 21.

[0034] It should be noted that the position of the thread groove 2 on the conveyor belt 102 is set at the part where it exceeds the length of the roller 101, so that when the conveyor belt 102 rotates, there will be no motion interference between the locking bolt 21 and the roller 101, and no contact will occur between the two, thereby avoiding damage to the roller 101 and ensuring the stability of the locking bolt 21.

[0035] Furthermore, the surface of the conveyor belt 102 is provided with arc grooves 3 located on both sides of the baffle 103, a circular tube 31 is provided in the arc groove 3, and a slot 32 is provided on the surface of the circular tube 31. A winding roller 33 is rotatably connected to the inside of the circular tube 31, and a barrier curtain 34 is wound on the surface of the winding roller 33. The non-fixed end of the barrier curtain 34 passes through the slot 32 and is fixedly connected to the surface of the baffle 103, and a first torsion spring 35 is installed between the winding roller 33 and the inner wall of the circular tube 31.

[0036] It should be noted that the circular tube 31 is adhered to the inside of the arc groove 3 by adhesive, so that the circular tube 31 has good contact tightness with the inner wall of the arc groove 3 and it is not easy to have a gap in the groove body.

[0037] In this embodiment, the width of the slot 32 is adapted to the thickness of the curtain 34, so that the curtain 34 is in close contact with the inner wall of the slot 32 without any large gap. In addition, the width of the curtain 34 is adapted to the length of the bar 103, so that the curtain 34 can block the bar 103 as much as possible.

[0038] It should be added that the surface of the curtain 34 is provided with a non-slip plastic film, so that the friction resistance of the Chinese herbal medicine slices when in contact with the curtain 34 is small. Therefore, when the curtain 34 moves, the Chinese herbal medicine slices piled on it will slide on its surface, making it difficult for the Chinese herbal medicine slices to get stuck at the junction of the curtain 34 and the groove 32.

[0039] During operation, when the baffle 103 moves to the roller 101 along with the conveyor belt 102, the conveyor belt 102 fits the surface of the roller 101 and is in an arc shape, so that a gap appears at the intersection of the baffle 103 and the conveyor belt 102. In addition, during this process, when the conveyor belt 102 is deformed, the parts on both sides of the baffle 103 will move relatively away from the baffle 103. Under the traction of this force, the curtain 34 overcomes the deformation force of the first torsion spring 35 and moves outward, so that it can always block the gap between the baffle 103 and the conveyor belt 102, thereby effectively preventing the occurrence of the situation where Chinese herbal medicine pieces are embedded in the gap between the two.

[0040] Example 2:

[0041] See also Figure 3-Figure 5 、 Figure 7 This embodiment provides a technical solution based on the above embodiment: cylindrical grooves 4 are symmetrically opened on both sides of the conveyor belt 102, and the inner side surface of the cylindrical groove 4 is rotatably connected with a positioning column 41, and a second torsion spring 42 is installed between the positioning column 41 and the inner wall of the cylindrical groove 4, and the outer end of the positioning column 41 is fixedly connected with a rotating piece 43, and the same arc cover 44 is fixedly connected between the rotating pieces 43 on both sides, and the bottom of both sides of the baffle 103 is fixedly installed with a guide frame 45.

[0042] It should be noted that the end of the curtain 34 away from the winding roller 33 passes upward from the bottom of the guide frame 45 and is fixedly connected to the surface of the barrier bar 103. The distance between the bottom end of the guide frame 45 and the surface of the conveyor belt 102 is greater than the distance between the slot 32 and the surface of the conveyor belt 102. Therefore, under the guide limit of the guide frame 45, the curtain 34 can fit the surface of the conveyor belt 102 as much as possible.

[0043] It should be further explained that the position and specifications of the arc cover 44 are compatible with the circular tube 31, and one side of the arc cover 44 is in contact with the surface of the conveyor belt 102, and the other side of the arc cover 44 presses the part of the curtain 34 tightly against the surface of the conveyor belt 102, so that the arc cover 44 can fully cover the circular tube 31, thereby effectively preventing the Chinese herbal medicine slices from being stuck in it when separation and cracks occur between the circular tube 31 and the arc groove 3.

[0044] In addition, in order to ensure that the arc cover 44 can always provide good protection for the circular tube 31, under normal working conditions, the second torsion spring 42 is in a compressed state, and under the action of the compression force, the end of the arc cover 44 away from the barrier bar 103 has a greater contact pressure with the surface of the conveyor belt 102, so that when the conveyor belt 102 is partially deformed later, the end in direct contact with the conveyor belt 102 can be rotated under the push of the compression force of the second torsion spring 42 and always maintain a fit state with the surface of the conveyor belt 102, while the other end will be slightly lifted up due to the traction of the barrier curtain 34, and can always be in fit with the surface of the barrier curtain 34.

[0045] It should be noted that the dimensions of the circular tube 31 and the arc cover 44 are relatively small, and the overall deformation of the conveyor belt 102 is relatively large when it is deformed. However, for local parts such as the installation of the circular tube 31 and the arc cover 44, the changes are relatively small. Therefore, when changes occur, the arc cover 44 and the curtain 34 are in a fine-tuning state, so that the two can be used in conjunction to effectively reduce the impact of the local deformation of the conveyor belt 102 on the barrier bar 103.

[0046] Example 3:

[0047] See also Figure 6 This embodiment provides a technical solution based on the above embodiment: a plurality of embedded grooves 5 corresponding to the baffles 103 are opened on the surface of the conveyor belt 102, and an inner embedded strip 51 adapted to the embedded grooves 5 is fixedly connected to the bottom surface of the baffle 103.

[0048] Through the cooperation between the inner embedded strip 51 and the embedded groove 5, the blocking strip 103 can be quickly positioned during installation, and in the subsequent use process, the supporting strength of the blocking strip 103 can be effectively guaranteed, so that it can stably carry out the loading work of Chinese herbal medicine slices.

[0049] Example 4:

[0050] This embodiment provides a method for feeding Chinese herbal medicine slices based on the above embodiment, using a feeding system for Chinese herbal medicine slices as described above, comprising the following steps:

[0051] S1, driving the roller shaft 101 by a motor so that the roller shaft 101 drives the conveyor belt 102 to rotate;

[0052] S2, the Chinese herbal medicine pieces to be transported are sent into the lower hopper 104, so that the Chinese herbal medicine pieces fall from the bottom of the lower hopper 104 onto the conveyor belt 102;

[0053] S3, through the baffle 103, the Chinese herbal medicine pieces falling on the conveyor belt 102 are restricted from sliding downward, so that the Chinese herbal medicine pieces are transported to the top along with the movement of the baffle 103 and the conveyor belt 102;

[0054] S4. The Chinese herbal medicine pieces fall from the top of the conveyor belt 102 to the next process position.

[0055] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
