Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece feeding machinery technology, specifically to a non-destructive square plate device and a feeding machine including the device. Background Technology
[0002] With the increasing demand for packaging materials such as granules, flakes, capsules, and toy building blocks, more and more feeding machines are appearing on the market. Feeding machines generally include a vibratory feeder, a vision inspection conveyor, and a feeding device. A vibratory feeder is an auxiliary feeding device for automatic assembly or automatic processing machinery. It generally includes a circular disc and a vibrating base. The material is fed to the vision inspection conveyor by the vibration of the vibrating base, spiraling upwards along the circular disc to the vision inspection conveyor. The vision inspection conveyor conveys and visually inspects the material. Finally, the material is sorted and fed down by the feeding device.
[0003] However, due to the characteristics of circular vibratory feeders for rotary conveying, there is a risk of material collision and overturning. Furthermore, the surface of vibratory feeders on the market is generally treated with flocking and spraying adhesive, which makes it easy for materials to have lint, stains, scratches, and other defects during the feeding process, making it impossible to achieve lossless conveying. Utility Model Content
[0004] To address the existing problems, this utility model proposes a non-destructive square tray device and a feeding unit containing the device, which realizes non-destructive conveying and avoids phenomena such as material sticking and scratching; and realizes independent control of feeding and returning materials.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A non-destructive vibrating disc device includes a feed channel, a screening channel, a return channel, a first vibrator, a second vibrator, and a vibrating base. Non-destructive vibrating disc felt is provided on the feed channel, the screening channel, and the return channel. The first and second vibrators are arranged in parallel and opposite directions on the vibrating base. The feed channel is placed on the first vibrator, and the screening channel and the return channel are placed on the second vibrator. The end of the feed channel is connected to the screening channel. The screening channel is provided with a screening port. The screening channel is connected to the return channel at the screening port. The return channel is connected to the front end of the feed channel.
[0007] Preferably, in the feed channel, the fibers on the non-destructive vibrating disc felt are arranged in a rearward direction, while in the screening channel and return channel, the fibers on the non-destructive vibrating disc felt are arranged in a forward direction.
[0008] Preferably, the feed channel is inclined upwards from the front end to the rear end.
[0009] Preferably, the screening channel is a V-shaped channel; and an adjustable plate is provided at the screening port, the adjustable plate and the screening channel forming an adjustable channel.
[0010] Preferably, a transverse transition section is provided between the end of the feed channel and the screening channel, and the heights of the end of the feed channel, the transverse transition section and the screening channel are sequentially reduced.
[0011] Preferably, the transverse transition section, the screening channel, and the return channel are designed as an integrated unit, and all three are placed on the second vertical vibrator.
[0012] Preferably, a baffle is provided on the transverse transition section.
[0013] Preferably, the return flow channel is positioned higher than the front end of the feed flow channel.
[0014] Preferably, the vibrating base has through holes on both sides for easy lifting.
[0015] On the other hand, this utility model also discloses a single feeding machine, including a frame and a feeding machine, a vision inspection conveying device, a discharging device, and a non-destructive square plate device as described above, all fixed on the frame.

[0016] Compared with the prior art, the present invention has the following advantages:
[0017] In this invention, the material is conveyed unidirectionally to the end of the feed channel by the vibration of the first vibrator. Then, the material enters the screening channel, where it is screened by the vibration of the second vibrator. Material that does not meet the preset specifications enters the return channel through the screening channel and returns to the front of the feed channel.

During this process, the unidirectional conveying of the feed channel avoids collisions and overturning. Furthermore, the feed channel, screening channel, and return channel are all equipped with non-destructive vibrating disc felt, preventing material from sticking with lint, stains, scratches, or abrasions, thus achieving non-destructive conveying. In addition, the feed channel, screening channel, and return channel are each controlled by the first and second vibrators, respectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] like Figures 1 to 4 The image shows a non-destructive vibrating disc device provided by this utility model, including a feed channel 1, a screening channel 2, a return channel 3, a first vibrator 4, a second vibrator 5, and a vibrating base 6. Non-destructive vibrating disc felt 7 is provided on the feed channel 1, the screening channel 2, and the return channel 3. The non-destructive vibrating disc felt 7 is as follows... Figure 4 As shown, in the feed channel 1, the fibers on the non-destructive vibrating disc felt 7 are oriented backward, while in the screening channel 2 and the return channel 3, the fibers on the non-destructive vibrating disc felt 7 are oriented forward; Figure 2 As shown, the first vertical vibrator 4 and the second vertical vibrator 5 are arranged in parallel and opposite directions on the vibrating base 6. The feed channel 1 is placed on the first vertical vibrator 4, and the screening channel 2 and the return channel 3 are placed on the second vertical vibrator 5; Figure 1 and Figure 2 As shown, the end of the feed channel 1 is connected to the screening channel 2. The screening channel 2 is provided with a screening port 21. The screening channel 2 is connected to the return channel 3 at the screening port 21. The return channel 3 is connected to the front end of the feed channel 1. Therefore, the feed channel 1, the screening channel 2 and the return channel 3 form a square plate channel structure.
[0031] In actual operation, the material enters the feed channel 1 from the feeder 20, is vibrated by the first vibrator 4, and is conveyed unidirectionally backward to the end of the feed channel 1. Then, the material enters the screening channel 2, and under the vibration of the second vibrator 5, it is conveyed forward to the screening port 21 for screening. Material that does not meet the preset requirements falls into the return channel 3 through the screening port 21 and is conveyed back to the front of the feed channel 1 under the vibration of the second vibrator 5. Material that meets the requirements is conveyed forward to the vision inspection conveying device 30. The non-destructive disc device operates in this cyclical manner to complete the feeding action. In this process, because the unidirectional conveying of the feed channel 1 replaces the rotary conveying of the disc vibrator, collisions and overturning of the material are avoided. Furthermore, non-destructive vibrating disc felt 7 is provided on the feed channel 1, screening channel 2, and return channel 3. It features high wear resistance, noise reduction, and scratch resistance, preventing material from sticking with lint or stains. Furthermore, the fiber direction of the non-destructive vibrating disc felt 7 on the feed channel 1 is consistent with the direction of material conveying on the feed channel 1 driven by the first vibrator 4. The fiber direction of the non-destructive vibrating disc felt 7 on the screening channel 2 and return channel 3 is consistent with the direction of material conveying on the screening channel 2 and return channel 3 driven by the second vibrator 5. That is, the fiber direction is consistent with the direction of material movement, which can greatly reduce friction and avoid scratches and abrasions during material conveying, achieving non-destructive conveying. In addition, the feed channel 1 and screening channel 2, and the feed channel 1 and return channel 3 are controlled by the first vibrator 4 and the second vibrator 5 respectively. Independent control allows for separate adjustment, separate start and stop, and no interference between them, thereby preventing material accumulation or gaps from affecting feeding.
[0032] Furthermore, such as Figure 1 As shown, the feed channel 1 is inclined upward from the front end to the end end, so that the material can be automatically and orderly conveyed to the end end under the vibration of the first vibrator 4.
[0033] Furthermore, such as Figure 3 As shown, in this embodiment, the screening channel 2 is a V-shaped channel with its bottom plate inclined to the inside of the side plate, so that the material can be concentrated at the angle between the bottom plate and the side plate and conveyed forward, making it easier for the material to enter the screening port 21 for screening.
[0034] like Figure 2As shown, an adjustable plate 22 is provided at the screening port 21. The adjustable plate 22 and the screening material flow channel 2 form an adjustable channel. The width of the adjustable plate 22 extending out of the screening port 21 can be adjusted according to the preset direction of the material entering the visual inspection conveyor 30 and the bottom size of the material in that direction. This adjusts the width of the adjustable channel. When the material enters the adjustable channel, the material whose bottom is far beyond the width of the adjustable channel will fall into the return flow channel 3 through the screening port 21, while the material whose bottom meets the width will continue to be conveyed forward to the visual inspection conveyor 30.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, a transverse transition section 8 is provided between the end of the feed channel 1 and the screening channel 2. The heights of the end of the feed channel 1, the transverse transition section 8 and the screening channel 2 decrease sequentially, so that the material can be smoothly conveyed from the end of the feed channel 1 to the transverse transition section 8 and from the transverse transition section 8 to the screening channel 2.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the transverse transition section 8, the screening channel 2, and the return channel 3 are designed as an integrated unit, and all three are placed on the second direct vibrator 5, while the feed channel 1 is placed on the first direct vibrator 4. The two vibrate separately and are controlled independently.
[0037] Furthermore, such as Figure 1 As shown, a baffle plate 81 is provided on the transverse transition section 8. On the one hand, it prevents a large amount of material on the transverse transition section 8 from falling into the return flow channel 3. On the other hand, when the material accumulates on the transverse transition section 8, it can pass over the baffle plate 81 and fall into the return flow channel 3 to continue to be transported in a cycle, thus playing a diversion role.
[0038] Furthermore, the return flow channel 3 is positioned higher than the front end of the feed flow channel 1, allowing the material to smoothly return from the return flow channel 3 to the front end of the feed flow channel 1 for continued circulation and conveying, thus preventing the material from getting stuck and accumulating at the connection point.
[0039] Furthermore, such as Figure 1 and Figure 2 As shown, the vibrating base 6 has through holes 61 on both sides for easy lifting.
[0040] This utility model also provides a single feeding machine, such as Figure 5 and Figure 6As shown, the system includes a frame 10 and a feeder 20, a vision inspection conveyor 30, a discharge device 40, and a non-destructive tray device as described above, all fixed on the frame 10. The discharge port of the feeder 20 is connected to the feed channel 1 of the non-destructive tray device. The material enters the feed channel 1 of the non-destructive tray device through the feeder 20. The screening channel 2 is connected to the vision inspection conveyor 30 at the front end of the screening port 21. After being screened by the non-destructive tray device, the material that meets the requirements continues to be conveyed to the front end and to the vision inspection conveyor 30. The vision inspection conveyor 30 performs vision inspection and conveying. The discharge port of the vision inspection conveyor 30 is connected to the feed port of the discharge device 40. Finally, the material enters the discharge device 40, which sorts and feeds it.
[0041] In this embodiment, as Figure 5 and Figure 6 As shown, the feeding unit is a two-in-one square tray feeding unit, which includes two feeding machines 20, two non-destructive square tray devices, a vision inspection conveying device 30 with dual channels, and a feeding device 40 with dual channels.
[0042] In other embodiments, the feeding unit may also be a single-pane feeding unit, which includes a feeding machine 20, a non-destructive pan device, a vision inspection conveying device 30 with a single channel, and a feeding device 40 with a single channel.
[0043] In summary, in this utility model, during the cyclic feeding process of the non-destructive square disc device, the unidirectional feeding of the feed channel 1 replaces the rotary feeding of the disc vibrating plate, thus avoiding material collisions and overturning. Furthermore, the feed channel 1, the screening channel 2, and the return channel 3 are all equipped with non-destructive vibrating plate felt 7, which can prevent material from sticking with lint or dirt. Moreover, the fiber direction on the non-destructive vibrating plate felt 7 is consistent with the direction of material movement, which can greatly reduce friction and prevent scratches and abrasions during material conveying, thus achieving non-destructive conveying. In addition, the feed channel 1 and the screening channel 2, as well as the feed channel 1 and the return channel 3, are controlled by the first vibrator 4 and the second vibrator 5, respectively. Independent control allows for separate adjustment, separate start and stop, and no interference between them, thereby preventing material accumulation or gaps from affecting the feeding process.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
