Description

Technical Field

[0001] This application relates to the technical field of tea production equipment, and in particular to a metal detection machine for tea. Background Technology

[0002] On automated tea production lines, metal objects may be deliberately added to the purchased tea raw materials to increase their weight. At the same time, the production line equipment may be operated for a long time without proper maintenance, which may cause small parts to loosen, fall off, and mix into the tea. Therefore, measures need to be taken to remove the metal objects mixed in with the tea to ensure product quality.

[0003] The existing announcement number CN221183783U, entitled "A Metal Detection Device for Tea Production Line," includes: a frame; a conveyor mounted on the frame; a metal detection device located in the middle of the conveyor, having a detection port facing the top surface of the conveyor; a sieving plate located on one side of the frame, below the end of the conveyor; and an alarm device mounted on the frame. The device monitors for metal impurities mixed in with the tea leaves by installing a metal detection device above the conveyor. The sieving plate separates tea leaves containing metal from those without. Tea leaves without metal directly enter the next production process, while tea leaves containing metal impurities are separated and moved to other locations.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the production of tea, a sieve plate is used to sieve metal impurities in the tea leaves. However, the tea can only sieve small-volume metal impurities and cannot remove large-volume metal impurities, thus affecting the cleanliness of the removal of metal impurities from the tea leaves. Utility Model Content

[0005] In order to overcome the problem that existing tea production methods use sieves to screen for metal impurities, but these methods can only screen out small-volume metal impurities and cannot remove large-volume metal impurities, thus affecting the cleanliness of metal impurity removal from tea, this application provides a tea metal detection machine.

[0006] The metal detector for tea leaves provided in this application adopts the following technical solution:

[0007] A metal detection machine for tea leaves includes a feeding frame box, a screening frame box, a magnetic separator, a sorting component, and a screening component. The bottom of the feeding frame box is vertically connected and fixed to the screening frame box, and the upper and lower end faces of the screening frame box are both through-type. Multiple insert frames are vertically through-type on the front vertical end face of the screening frame box. The magnetic separator, sorting component, and screening component all include a cover plate, and the magnetic separator, sorting component, and screening component are arranged sequentially in the vertical direction inside the screening frame box. The cover plate is inserted into the insert frame of the screening frame box. Multiple magnetic rods are horizontally assembled on the vertical end face of the cover plate of the magnetic separator. A sorting groove plate is horizontally fixed on the vertical end face of the cover plate of the sorting component. A screening mesh box is horizontally fixed on the vertical end face of the cover plate of the screening component.

[0008] By adopting the above technical solution, when removing metal impurities from tea leaves, the tea leaves are added from the top feeding port of the feeding frame box. The tea leaves fall into the screening frame box. As the tea leaves fall vertically downwards in the screening frame box, they pass through the magnetic separator, the sorting element, and the screening element in sequence. When the tea leaves fall downwards, they come into contact with multiple magnetic rods on the magnetic separator, which adsorb the iron fragments contained in the tea leaves. At the same time, when the tea leaves fall onto the sorting trough plate, they fall downwards through the sorting channel of the sorting trough plate. Large-volume waste iron impurities in the tea leaves are blocked by the sorting trough plate and remain on the top surface of the sorting trough plate. Then the tea leaves continue to fall and enter the screening screen box of the screening element. The tea leaves shake in the screening screen box, and small-volume impurities in the tea leaves fall and are discharged from the screening frame box. The tea leaves remain in the screening screen box. Thus, the metal impurities in the tea leaves are vertically filtered out in the screening frame box, and the tea leaves can separate metal impurities of different sizes, ensuring the cleanliness of the removal of metal impurities from the tea leaves.

[0009] Optionally, the inside of the feeding frame is horizontally rotatably connected to two feeding toothed rods, and a feeding motor is horizontally fixed on one side of the outside of the feeding frame, with the output end of the feeding motor fixed to the end of the feeding toothed rod.

[0010] By adopting the above technical solution, in order to avoid the accumulation and sticking of tea leaves during use, which would make it difficult to remove impurities from the tea leaves, the feeding frame box outer wall pusher motor is started to drive the pusher tooth rod to rotate in opposite directions. The pusher tooth rod is used to disperse the tea leaves and let the impurities in the tea leaves leak out, ensuring that the tea leaves are dispersed and easy to remove impurities and adsorb in the later stage.

[0011] Optionally, multiple supports are vertically and symmetrically arranged on both sides of the bottom of the screening box, and screws are threaded through the bottom of the multiple supports.

[0012] By adopting the above technical solution, multiple supports on the bottom surface of the screening box are used to support and stabilize the screening box. At the same time, the bottom ends of the multiple supports are locked and fixed by screws to ensure the vertical stability of the multiple supports.

[0013] Optionally, a support spring is vertically fixed to the top surface of the bracket, and the top of the support spring is fixed to the bottom surface of the screening box.

[0014] By adopting the above technical solution, the support spring on the bracket is used to support the screening box. The deformation force of the support spring drives the screening box to vibrate, which facilitates the screening of tea impurities and speeds up the screening process.

[0015] Optionally, a vibration motor is vertically fixed on the outer vertical end face of the screening box.

[0016] By adopting the above technical solution, the vibration motor installed on the outer wall of the screening box generates vibration force, which causes the support spring on the bracket to deform, and the shaking of the screening box accelerates the screening and processing effect of tea impurities.

[0017] Optionally, the outer wall of the screening box is vertically slidably connected to multiple lifting rods on the upper side of multiple insert frames, and the lifting rods are vertically sleeved with lifting springs, with the two ends of the lifting springs fixed to the upper and lower sides of the lifting rods respectively.

[0018] By adopting the above technical solution, when the screening box is locked with the magnetic separator, the sorting component and the screening component, the lifting rod slides vertically on the screening box, compressing the lifting spring to deform. The deformation force of the lifting spring facilitates the positioning of the lifting rod and the stable locking of the screening box with the magnetic separator, the sorting component and the screening component.

[0019] Optionally, a lifting hole frame is horizontally fixed on the outer vertical end face of the cover plate, and the lifting hole frame is slidably inserted into the bottom end of the lifting rod.

[0020] By adopting the above technical solution, when the positioning screening box is locked stably with the magnetic separator, sorting component and screening component, the lifting hole frame on the outside of the cover plate and the lifting rod are slidably inserted, which facilitates the improvement of the stability of the cover plate inserted into the insertion frame.

[0021] Optionally, a stud is horizontally fixed at the end of the magnetic rod, and a screw groove is horizontally opened on the side end face of the cover plate of the magnetic selector, and the screw groove is threadedly assembled and connected to the stud on the end of the magnetic rod.

[0022] By adopting the above technical solution, the stud thread at the end of the magnetic rod is assembled in the thread groove on the side end face of the cover plate, thus completing the assembly of the magnetic rod and the cover plate. The magnetic rod is used to adsorb metal impurities.

[0023] In summary, this application includes at least one of the following beneficial technical effects: When removing metal impurities from tea leaves, the tea leaves are added from the top feeding port of the feeding frame box. The tea leaves fall into the screening frame box. As the tea leaves fall vertically downwards in the screening frame box, they sequentially pass through a magnetic separator, a sorting element, and a screening element. As the tea leaves fall, they contact multiple magnetic rods on the magnetic separator, which adsorb the iron fragments contained in the tea leaves. Simultaneously, as the tea leaves fall onto the sorting trough plate, they fall through the sorting channels of the sorting trough plate. Large-volume scrap iron impurities in the tea leaves are blocked by the sorting trough plate and remain on the top surface of the sorting trough plate. Then, the tea leaves continue to fall and enter the screening mesh box of the screening element. The tea leaves shake in the screening mesh box, and small-volume impurities fall and are discharged from the screening frame box. The tea leaves remain in the screening mesh box. Thus, the metal impurities present in the tea leaves are vertically filtered and removed in the screening frame box. The tea leaves can separate metal impurities of varying sizes, ensuring the cleanliness of the metal impurity removal from the tea leaves. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a metal detector for tea leaves. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A metal detection machine for tea leaves includes a feeding frame box 1, a screening frame box 2, a magnetic separator 3, a sorting component 4, and a screening component 5. The bottom of the feeding frame box 1 is vertically connected and fixed to the screening frame box 2, and the upper and lower end faces of the screening frame box 2 are both through-connected. Multiple insert frames 21 are vertically connected and connected on the front vertical end face of the screening frame box 2. The magnetic separator 3, the sorting component 4, and the screening component 5 all include a cover plate 6, and the magnetic separator 3, the sorting component 4, and the screening component 5 are arranged sequentially in the vertical direction inside the screening frame box 2. The cover plate 6 is inserted into the insert frames 21 of the screening frame box 2. Multiple magnetic rods 31 are horizontally assembled on the vertical end face of the cover plate 6 of the magnetic separator 3. A sorting trough plate 41 is horizontally fixed on the vertical end face of the cover plate 6 of the sorting component 4. A screening mesh box 51 is horizontally fixed on the vertical end face of the cover plate 6 of the screening component 5.

[0034] By adopting the above technical solution, when removing metal impurities from tea leaves, the tea leaves are added from the top feeding port of the feeding frame box 1. The tea leaves fall into the screening frame box 2. As the tea leaves fall vertically downward in the screening frame box 2, they pass through the magnetic separator 3, the sorting component 4, and the screening component 5 in sequence. When the tea leaves fall downward, they come into contact with the multiple magnetic rods 31 on the magnetic separator 3, which adsorb the iron fragments contained in the tea leaves. At the same time, when the tea leaves fall onto the sorting trough plate 41, they fall downward from the sorting channel of the sorting trough plate 41. Large-volume scrap iron impurities in the tea leaves are blocked by the sorting trough plate 41 and remain on the top surface of the sorting trough plate 41. Then the tea leaves continue to fall and enter the screening box 51 of the screening component 5. The tea leaves shake in the screening box 51, and small-volume impurities in the tea leaves fall and are discharged from the screening box 2. The tea leaves remain in the screening box 51. Thus, the metal impurities in the tea leaves are vertically filtered and removed in the screening box 2. The tea leaves can separate metal impurities of different sizes, ensuring the cleanliness of the removal of metal impurities in the tea leaves.

[0035] Reference Figure 7 The inside of the feeding frame box 1 is horizontally rotatably connected to two feeding toothed rods 12, and a feeding motor 11 is horizontally fixed on one side of the outside of the feeding frame box 1, with the output end of the feeding motor 11 fixed to the end of the feeding toothed rods 12. During use, to prevent tea leaves from accumulating and sticking together, making it difficult to remove impurities, the feeding motor 11 on the outer wall of the feeding frame box 1 is activated to drive the feeding toothed rods 12 to rotate in opposite directions. The feeding toothed rods 12 disperse the tea leaves, allowing impurities to leak out, ensuring the tea leaves are dispersed for easy subsequent impurity removal and adsorption.

[0036] Reference Figure 3 The bottom of the screening box 2 has multiple vertically symmetrical supports 24 on both sides, with screws threaded through the bottom ends of each support 24. These supports 24 on the bottom surface of the screening box 2 support and stabilize it, and are secured with screws to ensure vertical stability. A support spring 241 is vertically fixed to the top surface of each support 24, with its top end fixed to the bottom surface of the screening box 2. The support spring 241 supports the screening box 2, and its deformation causes the screening box 2 to vibrate, accelerating the sieving of tea impurities. A vibration motor 25 is vertically fixed to the outer vertical end face of the screening box 2. The vibration motor 25 on the outer wall of the screening box 2 generates vibration, which causes the support spring 241 on the supports 24 to deform, thus accelerating the sieving of tea impurities.

[0037] Reference Figure 3 The outer wall of the screening box 2 is vertically slidably connected to multiple lifting rods 22 on the upper side of multiple insert frames 21. Lifting springs 23 are vertically sleeved on the outside of each lifting rod 22, with both ends of the springs fixed to the upper and lower sides of the lifting rods 22 respectively. When the screening box 2 is locked with the magnetic separator 3, the sorting component 4, and the screening component 5, the lifting rods 22 slide vertically on the screening box 2, compressing the lifting springs 23 to deform. The deformation force of the lifting springs 23 facilitates the positioning of the lifting rods 22, ensuring stable locking of the screening box 2 with the magnetic separator 3, the sorting component 4, and the screening component 5. A lifting hole frame 61 is horizontally fixed on the outer vertical end face of the cover plate 6, and the lifting hole frame 61 is slidably inserted into the bottom end of the lifting rods 22. When the positioning screening box 2 is locked stably with the magnetic separator 3, the sorting component 4 and the screening component 5, the lifting hole frame 61 on the outside of the cover plate 6 and the lifting rod 22 are slidably inserted to improve the stability of the cover plate 6 when inserted into the insertion frame 21.

[0038] Reference Figure 4 A stud 32 is horizontally fixed to the end of the magnetic rod 31. A threaded groove 33 is horizontally opened on the side end face of the cover plate 6 of the magnetic separator 3, and the threaded groove 33 is threadedly assembled with the stud 32 on the end of the magnetic rod 31. The stud 32 at the end of the magnetic rod 31 is threadedly assembled in the threaded groove 33 on the side end face of the cover plate 6, completing the assembly of the magnetic rod 31 and the cover plate 6. The magnetic rod 31 is used to adsorb metal impurities.

[0039] The implementation principle of a metal detection machine for tea leaves according to an embodiment of this application is as follows: During use, the magnetic separator 3, the sorting component 4, and the screening component 5 are inserted sequentially from top to bottom into multiple insert frames 21 of the screening box 2. When the screening box 2 is locked with the magnetic separator 3, the sorting component 4, and the screening component 5, the lifting rod 22 slides vertically on the screening box 2, compressing the lifting spring 23 to deform. The deformation force of the lifting spring 23 facilitates the lifting rod 22 to position the screening box 2 and lock it stably with the magnetic separator 3, the sorting component 4, and the screening component 5. When removing metal impurities from the tea leaves, the tea leaves are added from the top feeding port of the feeding box 1. The feeding motor 11 on the outer wall of the feeding box 1 is started, driving the feeding toothed rod 12 to rotate in opposite directions. The feeding toothed rod 12 disperses the tea leaves, which fall into the screening box 2. As the tea leaves fall vertically downward in the screening box 2... The tea leaves pass through the magnetic separator 3, the sorting unit 4, and the screening unit 5 in sequence. As the tea leaves fall, they come into contact with the multiple magnetic rods 31 on the magnetic separator 3, which adsorb the iron debris contained in the tea leaves. At the same time, as the tea leaves fall onto the sorting trough plate 41, they fall through the sorting channel of the sorting trough plate 41. Large-volume waste iron impurities in the tea leaves are blocked by the sorting trough plate 41 and remain on the top surface of the sorting trough plate 41. Then the tea leaves continue to fall and enter the screening mesh box 51 of the screening unit 5. The tea leaves shake in the screening mesh box 51, and small-volume impurities in the tea leaves fall and are discharged from the screening frame box 2. The tea leaves remain in the screening mesh box 51. The vibration motor 25 installed on the outer wall of the screening frame box 2 generates vibration force. The vibration force of the screening frame box 2 causes the support spring 241 on the bracket 24 to deform. The shaking of the screening frame box 2 accelerates the screening effect of tea impurities.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
