Description

Technical Field

[0001] The utility model relates to the field of strip product processing equipment, in particular to a discharging device of a strip product screening device. Background Art

[0002] In the production process of strip products such as chopsticks, after the products are processed and formed, it is often necessary to detect their quality and screen the strip products according to different qualities.

[0003] The existing strip product screening equipment includes an inclined conveying mechanism, and a strip product placement slot is horizontally arranged on the inclined conveying mechanism; an imaging position and a screening position are arranged on the strip product conveying path of the inclined conveying mechanism, and the imaging position and the screening position are sequentially distributed along the strip product conveying direction of the inclined conveying mechanism; a camera device for photographing the strip products at the imaging position is arranged on the side of the strip product conveying path of the inclined conveying mechanism; an air nozzle is arranged inside the strip product conveying path of the inclined conveying mechanism, and the air nozzles are arranged in one-to-one correspondence with the screening positions, and each air nozzle faces the corresponding screening position. After the camera device images the strip products conveyed to the imaging position on the inclined conveying mechanism, the quality of the strip products is graded according to the imaging data of the strip products; then, when the strip products of different grades are conveyed to the screening positions along with the inclined conveying mechanism, the strip products of the corresponding grades are blown out of the inclined conveying device by the air nozzles to complete the screening of different qualities.

[0004] When the existing strip product screening equipment discharges materials, the superior products are blown out and naturally fall into a collecting hopper. A pushing mechanism is arranged at one end of the strip products in the collecting hopper. By reciprocating and telescoping of the pushing mechanism along the length direction of the strip products, the strip products are pushed out of the collecting hopper and enter the next process. Since the strip products falling into the collecting hopper sometimes skew or warp, one or several strip products may turn up or rotate horizontally under the action of the instantaneous thrust applied by the pushing mechanism, resulting in blockage of the outlet, affecting normal discharging, and causing the machine to stop. Summary of the Utility Model

[0005] A first object of the utility model is to provide a discharging device of a strip product screening device, which can solve the problem that the qualified products will turn up or rotate horizontally during discharging in the prior art and cannot be discharged normally.

[0007] The utility model realizes the rejection and collection of unqualified products through the material rejection mechanism and the hopper. At the same time, the qualified products directly fall onto the horizontal conveying mechanism and are stably conveyed through the horizontal conveying mechanism, and there is no problem that the qualified products turn up or rotate horizontally during unloading and cannot be unloaded normally.

[0008] Further, the number of the screening positions is ≥ two, and the screening positions are sequentially distributed on the strip product conveying path of the downward section, and each screening position is correspondingly provided with the material rejection mechanism and the hopper.

[0015] The following describes in detail the preferred embodiments of the unloading device of the strip product screening device of the utility model with reference to the drawings:

[0016] As Figure 1 、 Figure 2As shown in the figure, a discharging device for a strip product screening equipment includes a conveying mechanism 10, and a plurality of strip product placement slots 11 are sequentially arranged on the conveying mechanism 10 along its conveying direction; the conveying mechanism 10 has a downward section 101, and a screening position is provided on the strip product conveying path of the downward section 101 for screening out unqualified products (unqualified strip products); at the screening position, a material removing mechanism (the same as the air nozzle structure in the Chinese patent with the authorization announcement number CN217534312U, so it is not shown) and a hopper 30 for receiving the unqualified products removed by the material removing mechanism are provided; at the turning position at the bottom end of the downward section 101, a horizontal conveying mechanism 40 is provided for receiving the qualified products (qualified strip products) that are conveyed to the turning position at the bottom end of the downward section 101 and naturally fall down.

[0017] During operation, the strip products are horizontally placed on the strip product placement slots 11 of the conveying mechanism 10; when the strip products are conveyed through the screening position, the unqualified products are removed and collected through the material removing mechanism and the hopper 30 at the screening position; at the same time, the qualified products continue to be conveyed downward by the downward section. When the qualified products are conveyed to the turning position at the bottom end of the downward section 101, they will naturally fall from the strip product placement slot 11 and land on the horizontal conveying mechanism 40; then they are stably conveyed and discharged by the horizontal conveying mechanism 40.

[0018] Since the qualified products of the present utility model are received and stably conveyed and discharged by the horizontal conveying mechanism 40, there is no problem that the qualified products turn up or rotate horizontally during discharging.

[0019] Preferably, as Figure 1 、 Figure 2 shown, the number of the screening positions is multiple (for example, five), and each of the screening positions is sequentially distributed on the strip product conveying path of the downward section, and each screening position is correspondingly provided with the material removing mechanism and the hopper 30. During operation, the quality of the strip products can be graded through the imaging device and the imaging data before the strip products reach the screening position; for strip products of different grades, when they are conveyed to each screening position of the downward section 101 by the conveying mechanism 10, the corresponding grade of strip products are removed from the conveying mechanism 10 by the material removing mechanism. Of course, the number of the screening positions can be but is not limited to five in the drawings, and the specific number can be adjusted arbitrarily according to needs.

[0020] Furthermore, as Figure 1 、 Figure 2 shown, the horizontal conveying mechanism 40 is arranged along the transverse direction parallel to the conveying mechanism 10, and baffle plates 41 are respectively provided on the left and right sides of the upper surface of the horizontal conveying mechanism 40 for preventing the strip products from sliding off from the left and right sides of the horizontal conveying mechanism 40. Of course, the conveying direction of the horizontal conveying mechanism 40 can be but is not limited to being arranged along the transverse direction parallel to the conveying mechanism 10.

[0021] Furthermore, as Figure 2 shown, a receiving hopper 50 and a lifting and feeding device 60 are successively provided at the output end of the horizontal conveying mechanism 40. The strip-shaped materials are transferred to the next process through the receiving hopper 50 and the lifting and feeding device 60.

[0022] Furthermore, the material rejection mechanism and the corresponding hopper 30 are respectively arranged on the inner and outer sides of the strip-shaped product conveying path in the downward section 101 (the same as the air nozzle structure in the Chinese patent with the authorization announcement number CN217534312U, so it is not shown), and the layout is more reasonable. In the specific implementation process, the material rejection mechanism is an air nozzle arranged on the inner side of the strip-shaped product conveying path in the downward section 101, and the air nozzle faces the corresponding screening position, and can blow the strip-shaped products passing through the screening position off from the strip-shaped product placement slot 11 to achieve rejection. At this time, the hopper 30 corresponding to the material rejection mechanism is located on the outer side of the strip-shaped product conveying path and is used to receive the strip-shaped products blown off by the material rejection mechanism. The material rejection mechanism and the hopper 30 of the present utility model are respectively the same as the air nozzle and the collection box structure in the Chinese patent with the authorization announcement number CN217534312U, and will not be elaborated here. Of course, the material rejection mechanism can be, but is not limited to, an air nozzle, and can also be a pushing mechanism, etc.

[0023] For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can also be made, and all should be regarded as belonging to the protection scope of the present utility model.
