Description

Technical field:

[0001] The utility model relates to a foreign matter detection device for preparing characteristic Wuyi rock tea. Background technology:

[0002] Rock tea leaves are in the form of strips. In the industrial production process of rock tea leaves, metal objects are artificially added to increase the weight when purchasing the tea raw materials at the front end. At the same time, the equipment on the production line has been running for a long time, and the maintenance of the equipment is not in place, and the screws and nuts may loosen and fall into the tea leaves. Therefore, it is necessary to remove the metal objects mixed in the tea leaves. At present, a metal detector is directly installed above the tea conveyor belt to detect whether the tea leaves are mixed with metal foreign objects. For example, a tea conveyor that can automatically remove metal foreign objects is disclosed in Chinese Patent Publication No. CN209020790U. When removing metal foreign objects in the above patent, the tea leaves and the mixed metal foreign objects first fall into the guide plate assembly, then slide along the guide plate assembly to the first drop hopper, and finally enter the receiving frame, thereby realizing the automatic removal of metal foreign objects. However, when realizing the removal of metal foreign objects in the above patent, the tea leaves and the mixed metal foreign objects are uniformly sent into the receiving frame, and the tea leaves in the receiving frame are not separated from the metal foreign objects, which is easy to cause tea waste. To this end, it is necessary to improve the above-mentioned technical problems, and this case arises from this. Utility model content:

[0003] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a foreign matter detection device for the preparation of characteristic Wuyi rock tea.

The longitudinal pushing assembly is used to push the tea leaves containing metal foreign matter detected by the metal detector on the conveyor belt backwards to the discharging slide, the discharging slide is inclined with a high front end and a low rear end, and a metal removal assembly is arranged directly below the lower end of the discharging slide.

[0005] Furthermore, the conveyor belt is arranged horizontally, and the front and rear sides of the conveyor belt are respectively provided with a front lateral baffle and a rear lateral baffle, and the front and rear lateral baffles are provided with a longitudinally through-going clearance slot, and the clearance slot is opposite to the position of the metal detector; the longitudinal pushing assembly and the discharging slide plate are respectively opposite to the positions of the clearance slots on the front lateral baffle and the rear lateral baffle.

[0006] Furthermore, the longitudinal pushing assembly includes a pushing plate laterally arranged in front of a clearance slot of the front lateral baffle, and there is a gap between the bottom surface of the pushing plate and the top surface of the conveyor belt. The pushing plate is driven by a pushing cylinder longitudinally arranged on its front side to pass through the clearance slot of the front lateral baffle and move toward the rear lateral baffle.

[0007] Furthermore, the discharging slide plate is groove-shaped, and the upper port of the discharging slide plate is located below the yielding slot of the rear lateral baffle.

[0008] Furthermore, a receiving frame for receiving tea leaves is provided below the lower end of the discharging slide plate, and the metal removal component is located inside the upper end of the receiving frame.

[0009] Furthermore, the metal removal assembly includes a transversely arranged removal roller, the outer surface of which is coaxially sleeved with a cylindrical adsorption magnet, and the removal roller is driven to rotate by a motor installed on the outer wall of the material receiving frame.

[0010] Compared with the prior art, the utility model has the following effects: the utility model has a simple and reasonable structural design. By arranging a longitudinal pushing assembly and a discharging slide plate, the tea leaves containing metal foreign objects detected by a metal detector can be pushed backward to the discharging slide plate, so that the tea leaves and metal foreign objects can be removed from the conveyor belt. After that, the metal foreign objects mixed in the tea leaves are removed by the metal removal piece under the discharging slide plate, which facilitates the recycling of tea leaves and reduces waste.

[0015] like Figures 1-2As shown, the utility model is a foreign body detection device for preparing characteristic Wuyi rock tea, comprising a conveyor belt 1 for conveying tea from left to right, a metal detector 2 is arranged directly above the conveyor belt 1, and a longitudinal pushing assembly 3 and a discharging slide 4 are respectively arranged on the front and rear sides of the conveyor belt directly below the metal detector 2, and the longitudinal pushing assembly 3 is used to push the tea containing metal foreign bodies detected by the metal detector 2 on the conveyor belt 1 backward to the discharging slide 4, and the discharging slide 4 is inclined with a high front end and a low rear end, and a metal removal assembly is arranged directly below the lower end of the discharging slide 4. During operation, the conveyor belt conveys tea from left to right, and the metal detector detects the tea passing directly below it. When the metal detector detects metal foreign bodies, the conveyor belt stops moving, and then the longitudinal pushing assembly pushes the tea directly below the metal detector backward to the discharging slide, and the tea and the mixed metal foreign bodies fall into the discharging slide, and slide down along the discharging slide to the metal removal assembly, and the metal removal assembly removes the metal foreign bodies, which is convenient for recycling tea and reducing waste. .

[0016] In this embodiment, the conveyor belt 1 is arranged horizontally, and the front and rear sides of the conveyor belt 1 are respectively provided with a front lateral baffle 5 and a rear lateral baffle 6, and the front lateral baffle 5 and the rear lateral baffle 6 are provided with a longitudinally through-going clearance slot 7, and the clearance slot 7 is opposite to the position of the metal detector 2; the longitudinal pushing assembly 3 and the discharging slide plate 4 are respectively opposite to the clearance slot 7 on the front lateral baffle 5 and the rear lateral baffle 6 to achieve clearance when pushing tea leaves.

[0017] In this embodiment, the longitudinal pushing assembly 3 includes a pushing plate 8 which is laterally arranged in front of the yielding slot 7 of the front lateral baffle 5. There is a gap of 1-2 mm between the bottom surface of the pushing plate 8 and the top surface of the conveyor belt 1 so that the pushing plate can generate friction with the surface of the conveyor belt when moving longitudinally. The pushing plate 8 is driven by a pushing cylinder 9 longitudinally arranged on its front side to pass through the yielding slot 7 of the front lateral baffle 5 and move toward the rear lateral baffle 6. The pushing plate moves under the drive of the pushing cylinder to achieve the longitudinal pushing of the tea leaves on the conveyor belt.

[0019] In this embodiment, a receiving frame 10 for receiving tea leaves is provided below the lower end of the discharging slide plate 4 , and the metal removal component is located inside the upper end of the receiving frame 10 .

[0020] In this embodiment, the metal removal assembly includes a transversely arranged removal roller 11, the outer surface of which is coaxially sleeved with a cylindrical adsorption magnet 12, and the removal roller is driven to rotate by a motor (not shown) installed on the outer wall of the material receiving frame 10. During operation, the tea leaves and the mixed metal foreign matter on the discharging slide fall on the surface of the adsorption magnet, and the rotating adsorption magnet directly adsorbs the metal foreign matter, while the tea leaves fall into the material receiving frame, thereby achieving the removal of the metal foreign matter mixed in the tea leaves.

[0021] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0022] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0023] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
