[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0033] Please refer to Figs. 1-2 This is a schematic diagram of a feeding detection device for a material receiving machine according to an embodiment of the present invention. The feeding detection device includes a mounting plate 1, a feeding guide wheel 2, a material baffle 3, a feeding limit sensor 4, and a discharge margin sensor 5. The feeding guide wheel 2 is rotatably mounted on the mounting plate 1. The material belt is received by the material receiving machine after passing through the feeding guide wheel 2. The feeding guide wheel 2 has an infeed side away from the material receiving machine and an outfeed side close to the material receiving machine. There are two material baffles 3, which are mounted on the mounting plate 1 and located below the feeding guide wheel 2. Both material baffles 3 extend from the infeed side of the feeding guide wheel 2, and there is a baffle gap between the two material baffles corresponding to the width of the material belt. The feeding limit sensor 4 is mounted on the mounting plate 1, and the sensing end of the feeding limit sensor 4 is located below the baffle gap. The discharge margin sensor 5 is mounted on the mounting plate 1 and located below the feeding guide wheel 2, with the sensing end of the discharge margin sensor 5 facing the discharge side.
[0034] In practical implementation, the feed limit sensor 4 can be set as a contact sensor. When the feed strip on the feed side falls onto the feed limit sensor 4, the feed limit sensor 4 sends a sensing signal, and the take-up machine can take up the material at high speed based on this signal; when the feed strip on the feed side does not fall onto the feed limit sensor 4, the feed limit sensor 4 does not send a sensing signal, and the take-up machine takes up the material at low speed. It should be noted that high speed and low speed are relative concepts here. One of them can be set as a preset value, and the other can be set to a higher or lower value relative to the preset value. For example, if the low-speed take-up is the preset take-up speed, then the high-speed take-up is a speed that is relatively faster than this preset take-up speed.
[0035] In practical implementation, the discharge margin sensor 5 can be set as a photoelectric sensor. When the material belt on the discharge side hangs down and blocks the photoelectric signal emitted by the photoelectric sensor, the discharge margin sensor 5 emits a sensing signal, and the receiving machine can collect the material at high speed based on this signal; when the material belt on the discharge side does not hang down and block the photoelectric signal emitted by the photoelectric sensor, the discharge margin sensor 5 does not emit a sensing signal, and the receiving machine collects the material at low speed.
[0036] In specific implementation, to facilitate the adjustment of the material strip margin value (hereinafter referred to as trigger margin) that can trigger the feed limit sensor 4 on the feed side, and to improve the applicability of the feed detection device of the take-up machine in this embodiment, such as... Fig. 2 As shown, a feed limit sensor 4 can be mounted on the mounting plate 1 via a feed mounting assembly 6. The feed mounting assembly 6 includes a mounting crossbar 61 and a first clamping block 62. The first end of the mounting crossbar 61 is mounted on the mounting plate 1, and the second end extends towards the feed side away from the mounting plate 1. The first clamping block 62 is clamped to the second end of the mounting crossbar 61 via a first clamping groove, and the feed limit sensor 4 is clamped in a second clamping groove on the first clamping block 62. At this time, the trigger margin can be adjusted by adjusting the position of the first clamping block 62 on the mounting crossbar 61, that is, adjusting the lateral distance between the feed limit sensor 4 and the feed guide wheel 2.
[0037] In a specific implementation, the feeding mounting assembly 6 can be further configured to include a mounting rod 63 and a second clamping block 64. The first end of the mounting rod 63 is clamped in a second clamping groove, and the second end extends downwards towards the feeding guide wheel 2. The second clamping block 64 is clamped to the second end of the mounting rod 63 via a third clamping groove. The feeding limit sensor 4 is clamped in a fourth clamping groove on the second clamping block 64. At this point, the trigger margin can be adjusted by adjusting the position of the second clamping block 64 on the mounting rod 63, i.e., adjusting the longitudinal distance between the feeding limit sensor 4 and the feeding guide wheel 2.
[0038] In specific implementation, to make the material receiving machine feeding detection device in this embodiment applicable to different types of material belts and expand its application range, such as... Fig. 1 As shown, two material baffles 3 can be mounted on the mounting plate 1 via a baffle fixing plate 7. The baffle fixing plate 7 is provided with a waist-shaped hole 71, and both material baffles 3 are mounted on the baffle fixing plate 7 via the waist-shaped hole 71.
[0039] In specific implementation, such as Fig. 2 As shown, the mounting plate 1 can also be configured with at least two limiting arc grooves 11, each of which is an arc segment on the same ring; the baffle plate 7 is mounted on the mounting plate 1 via the limiting arc grooves 11. In this case, the baffle plate 7 has at least two fixing holes corresponding to the limiting arc grooves 11. When the fixing holes are fixed to different positions within the corresponding limiting arc grooves 11 by fixing screws, the angle of the material baffle 3 on the baffle plate 7 relative to the material conveying direction is different. This is to facilitate handling material drooping in different application scenarios and to facilitate adjusting the position when the longitudinal position of the feed limit sensor 4 relative to the feed guide wheel 2 changes.
[0040] In summary, the material receiving machine feeding detection device in this embodiment has a material baffle 3 located below the feeding guide wheel 2 on the feeding side, and a feeding limit sensor 4 with its sensing end located below the material baffle 3 on the feeding side. This allows the material strip to be confined to the feeding limit sensor 4 for accurate feeding side clearance detection. When there is a large amount of material strip clearance on the feeding side (the material strip hangs down onto the feeding limit sensor 4, and the feeding limit sensor 4 sends a sensing signal), the material receiving machine can collect the material at high speed based on the signal from the feeding limit sensor 4. When there is a small amount of material strip clearance on the feeding side (the material strip does not hang down onto the feeding limit sensor 4, and the feeding limit sensor 4 does not send a sensing signal), the material receiving machine collects the material at low speed. At the same time, by setting a discharge clearance sensor 5 on the discharge side of the feeding guide wheel 2, the detection device can provide more comprehensive feedback on the material strip clearance signal, further improving the practicality of the device.
[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
