[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Example 1

[0026] A qualified product screening device for powder cake production includes a feeding conveyor belt 1 for conveying products, a weighing conveyor belt 2 located at the end of the feeding conveyor belt 1, and a collection device 4 located at the end of the weighing conveyor belt 2. A weighing sensor is installed inside the weighing conveyor belt 2. It should be noted that both ends of the feeding conveyor belt 1 and the weighing conveyor belt 2 are provided with a driving roller and a driven roller, and the two driving rollers are respectively connected to a drive motor, thereby driving the rotation and conveying of the feeding conveyor belt 1 and the weighing conveyor belt 2. The specific setting and working principle are mature existing technologies in this field and will not be described in detail here.

[0027] The collecting device 4 includes a receiving plate 42 for receiving the products at the end of the weighing conveyor belt 2. The receiving plate 42 is connected to a driving mechanism for swinging the receiving plate 42. A collecting component 41 is respectively provided below both ends of the swing direction of the receiving plate 42. The collecting component 41 can be a collecting box or a conveyor belt.

[0028] The weighing sensor is electrically connected to the drive mechanism.

[0029] Working principle: When this utility model is in use, the powder cake box product is transported by the feeding conveyor belt 1, and then the product is transported by the feeding conveyor belt 1 to the weighing conveyor belt 2. It should be noted that an infrared sensor is installed above the weighing conveyor belt 2. The infrared sensor is electrically connected to the drive motor of the weighing conveyor belt 2, and both are electrically connected to the external central control system.

[0030] Once the product is delivered onto the weighing conveyor belt 2, the infrared sensor detects that a product has entered the weighing conveyor belt 2 and transmits the signal to the central control system, which then controls the drive motor of the weighing conveyor belt 2 to stop working. At this time, the weighing sensor under the weighing conveyor belt 2 can be used to weigh the product and transmit the weighing data to the central control system. For example, the principle of the weighing device for checked baggage at the airport is the same, and the details will not be elaborated further.

[0031] Since the central control system has a pre-set weight range for qualified products in the compact box (e.g., 20g ± 1g), it controls the drive mechanism to tilt the receiving plate 42 to one side based on whether the detected product weight is within this range. For example, it can be set so that the left collection piece 41 collects unqualified products and the right collection piece 41 collects qualified products. If the product is detected as qualified, the receiving plate 42 is controlled to tilt to the right to collect the qualified product into the right collection piece 41. Conversely, it tilts to the left to collect the unqualified product into the left collection piece 41.

[0032] Specifically, in this embodiment, the left collection unit 41 collects defective products, and the right collection unit 41 collects qualified products. If a qualified product is detected at the weighing conveyor belt 2, the receiving plate 42 is tilted to the right. Simultaneously, the central control system controls the drive motor of the weighing conveyor belt 2 to operate, using the weighing conveyor belt 2 to transport the qualified product. The qualified product falls from the end of the weighing conveyor belt 2 onto the receiving plate 42. Since the receiving plate 42 is tilted to the right at this time, the qualified product can be directly transported along the receiving plate 42 to the right collection unit 41. Conversely, if the product is not qualified, the receiving plate 42 tilts to the left, thus transporting the defective product to the right collection unit 41. The qualified products are collected into the collection unit 41 on the left, which will not be described in detail here. It can be seen that the qualified product screening device for powder compact production of this utility model can conveniently weigh, screen and collect powder compact products without the need for manual handling of each powder compact box to move, weigh, screen and collect, which greatly improves work efficiency and reduces labor intensity. In addition, the collection unit 41 can be a collection box or a conveyor belt. If it is a conveyor belt, it is directly set at the lower end of the inclined direction of the receiving plate 42, which makes it easy to directly receive the products coming down from the receiving plate 42 and promptly convey the products downwards for centralized collection or processing, etc.

[0033] In this embodiment, the driving mechanism includes a rotating shaft 44 disposed at the bottom of the receiving plate 42 along the width direction of the receiving plate 42. One end of the rotating shaft 44 is connected to a driving device 43 for driving the rotating shaft 44 to rotate. The driving device 43 can be a rotary cylinder or a rotary motor. In this embodiment, a rotary motor is selected. In this way, the central control system directly controls the forward or reverse rotation of the rotary motor, thereby controlling the forward or reverse rotation of the rotating shaft 44, and thus controlling the receiving plate 42 to swing to the left or right.

[0034] Preferably, the swing direction of the receiving plate 42 is set to be perpendicular to the conveying direction of the weighing conveyor belt 2; for example, in Figure 1, in the three-dimensional direction, the conveying direction of the weighing conveyor belt 2 is the x-axis direction, and the swing direction of the receiving plate 42 is the y-axis direction. In this way, the finished products falling from the end of the weighing conveyor belt 2 fall directly onto the receiving plate 42, and the left and right swing space of the receiving plate 42 is larger, and the products can be delivered to the collection box more conveniently and smoothly.

[0035] In this embodiment, a guide plate 3 is detachably installed at the conveying end of the weighing conveyor belt 2, and the end of the guide plate 3 is located above the receiving plate 42. Preferably, the guide plate 3 is inclined, and the lower end of the inclination faces the receiving plate 42. In this way, the finished product can be delivered directly to the receiving plate 42 more smoothly using the guide plate 3, avoiding or reducing the risk of damage to the finished product when it falls due to the height difference, and better protecting the quality of the finished product.

[0036] In this embodiment, arc-shaped protective plates 5 are provided on both sides of the guide plate 3. The height of the arc-shaped protective plates 5 can avoid the risk of the powder compact box flying out of the guide plate 3 from the side of the guide plate 3, and can better guide the powder compact box.

[0037] In this embodiment, positioning frames 6 are installed on both sides of the guide plate 3. The guide plate 3 and the positioning frames 6 are detachably connected, such as by a shaft connection or multiple bolt fixing positions. This makes it easier to adjust the tilt angle of the guide plate 3 and makes it more convenient and reliable to use.

[0038] In this embodiment, the feeding conveyor belt 1 is inclined, with the lower end of the inclination facing the weighing conveyor belt 2, which facilitates the product to enter the weighing conveyor belt 2 more easily.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
