[0005] As a more preferred scheme, the end positioning support is longitudinally slidingly installed on the rack, and the end positioning support is driven by longitudinal positioning drive device.

[0006] As a more preferred scheme, the pressing plate is also provided with detection sensor for detecting whether the end of thermal insulation cotton is bulged, and the detection sensor is close to the end blocking positioning beam.

[0007] As a more preferred solution, the detection sensor is a proximity switch, and the lower end of the proximity switch is higher than the bottom of the pressure roller.

[0008] As a more preferred solution, the side positioning device comprises a lifting frame vertically slidingly mounted on the frame, and the lifting frame is driven by a lifting power device; the upper end of the lifting frame is provided with a plurality of support bars, each of which is located in the gap between adjacent main conveying rollers of the main conveying roller set; each support bar is provided with a guide roller set perpendicular to the conveying direction of the main conveying roller set; one side of the frame is provided with a side reference plate, and the other side is provided with a side positioning plate slidingly mounted laterally; the side positioning plate is driven by a side positioning power device to approach the side positioning plate.

[0015] Since the side reference plate is transversely slidingly installed on the frame and is driven by the position adjusting power device, the transverse position of the side reference plate can be adjusted to meet the positioning requirements of the insulation cotton of different sizes.

[0016] Since the side reference plate and the side positioning plate are both provided with inclined avoidance slopes at the two ends, the two ends of the side reference plate and the side positioning plate will not contact the side edges of the insulation cotton, so that the hooking and pulling between the end and the side of the insulation cotton is avoided.

DETAILED DESCRIPTION

[0022] The utility model will be described in further detail below through specific examples.

[0023] As Figures 1 to 3 shown, a positioning device for thermal insulation cotton of solar heat collector, including rack 1, be provided with main conveying roller 5 group for conveying thermal insulation cotton on the rack 1, wherein main conveying roller 5 group includes several interval arrangement main conveying roller 5, the rack 1 is installed with the conveying motor 2 of driving the rotation of main conveying roller, and the conveying motor 2 is driven through chain transmission between main conveying roller.

[0024] The main conveying roller 5 group is provided with a positioning station, and the thermal insulation cotton can position the end and the side edge on the positioning station.

[0025] The rack 1 is installed with side positioning device 3 and end positioning device 4 at the positioning station, and the side positioning device 3 is used to position the long side of the thermal insulation cotton.

[0026] As Figure 1 and Figure 2 shown, the side positioning device 3 is located at the upstream of the end positioning device 4. The side positioning device 3 includes lifting frame 31 vertically slidingly installed on the rack 1, and the lifting frame 31 is driven by jacking power device 34, wherein the jacking power device 34 selects a synchronous cylinder. Since the length of the lifting frame 31 is relatively long, the lifting frame 31 is lifted and installed on the rack 1 by the synchronous lifting mechanism 33, and the synchronous lifting mechanism 33 selects a plurality of worm gear screw synchronous lifters.

[0027] The upper end of the lifting frame 31 is provided with a plurality of support bars 32, each of which is located in the gap between adjacent main conveying rollers 5 of the main conveying roller 5 group, and each of the support bars 32 is provided with a guide wheel group 35 perpendicular to the conveying direction of the main conveying roller 5 group, so as to facilitate the transverse conveying of the thermal insulation cotton. One side of the rack 1 is provided with a side reference plate 36, and the other side is transversely slidably provided with a side positioning plate 38. The side positioning plate 38 is driven to approach the side positioning plate 38 by a side positioning power device 39. The side positioning power device 39 is preferably a rodless cylinder, and is also arranged in the gap between the main conveying rollers 5. The side reference plate 36 is transversely slidably arranged on the rack 1, and is driven by a position adjusting power device 37. Similarly, the position adjusting power device 37 is preferably a cylinder, and the side reference plate 36 is driven by the cylinder, so that the position of the side reference plate 36 can be adjusted according to the size of the thermal insulation cotton and the set positioning position, and the flexibility is higher. The side reference plate 36 and the side positioning plate 38 are both provided with inclined avoidance slopes 361 at both ends. In this way, the ends of the side reference plate 36 and the side positioning plate 38 do not contact the side wall of the thermal insulation cotton, so as to avoid the end processing burr from hooking the thermal insulation cotton.

[0028] As shown in Figure 1 and Figure 3 The end positioning device 4 is used for positioning the short side of the thermal insulation cotton. The end positioning device 4 comprises two end positioning supports 41 respectively arranged on both sides of the rack 1. In this embodiment, the end positioning supports 41 are longitudinally slidably arranged on the rack 1, and are driven by a longitudinal positioning driving device 43. The longitudinal positioning driving device 43 can also be a rodless electric cylinder. In this way, the position of the end positioning support 41 can be adjusted, so as to satisfy the end positioning of different positions. At the same time, the rodless electric cylinder can also drive the end positioning support 41 to actively approach the thermal insulation cotton, and then move to the positioning position together with the thermal insulation cotton, so as to further reduce the extrusion of the thermal insulation cotton and avoid the arching of the thermal insulation cotton.

[0029] The end positioning support 41 is vertically slidably provided with a transversely extending end blocking positioning beam 42, which is driven to rise and fall by a positioning lifting power device 44. The end blocking positioning beam 42 is provided with an upwardly extending pressing plate 45, which is horizontally arranged and perpendicular to the end blocking positioning beam 42. The pressing plate 45 is vertically and elastically slidably provided with a plurality of transversely extending pressing wheels 47, one of which is in transmission connection with a forward and reverse driving motor 48 on the pressing plate 45. The transmission at this position can adopt chain transmission or belt transmission. Although the pressing wheel 47 is elastically slidably arranged, the elastic sliding stroke of the pressing wheel 47 can be controlled to be relatively small, so as not to affect the transmission reliability between the pressing wheel 47 and the forward and reverse driving motor 48.

[0030] The pressing wheel 47 is higher than the bottom of the end blocking positioning beam 42. The pressing plate 45 is further provided with a detection sensor 46 for detecting whether the end of the thermal insulation cotton is bulged, and the detection sensor 46 is close to the end blocking positioning beam 42. The detection sensor 46 is a proximity switch, and the lower end of the proximity switch is higher than the bottom of the pressing wheel 47.

[0031] Therefore, normally, the detection sensor 46 cannot sense the thermal insulation cotton because the lower end of the detection sensor 46 is higher than the bottom of the pressing wheel 47. When the thermal insulation cotton is bulged, the detection sensor 46 is triggered to detect the thermal insulation cotton. In the embodiment, the detection sensor 46 is arranged in a transverse row, and of course, can be arranged in multiple rows and located between adjacent pressing wheels 47.

[0032] The above-described embodiments are only preferred embodiments of the present application, and are not intended to limit the scope of the present application. Various modifications and improvements of the technical solutions of the present application made without departing from the design spirit of the present application shall fall within the protection scope of the present application as defined by the claims.
