Description

Technical Field

[0001] The invention relates to the field of roller production and processing equipment, in particular to a pneumatic feeding device for tapered rollers. Background Art

[0002] During the finishing process of tapered rollers, the material sorter and the grinder are often used in conjunction with each other. The material sorter corrects the disordered rollers and places them into the grinder with the small end facing forward. In the prior art, the roller conveying channel between the material sorter and the grinder is usually a vertically distributed tubular structure, which relies entirely on the rollers' own gravity to slide from the tubular structure into the grinder. As a result, the material sorter is set much higher than the feed port of the grinder, generally reaching more than 2 meters. Not only is the process of feeding materials into the material sorter difficult, requiring the cooperation of an overhead crane and consuming a lot of manpower, but the high setting of the material sorter also poses many safety hazards in the process of feeding materials into the material sorter. Summary of the Invention

[0003] The present invention aims to provide a pneumatic feeding device for tapered rollers, so as to shorten the relative distance between a material processing machine and a grinding machine, reduce the setting height of the material processing machine, thereby facilitating material feeding and reducing safety hazards.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a pneumatic feeding device for tapered rollers, comprising a feeding barrel distributed in a vertical direction, the upper end of the feeding barrel being connected to a roller processing machine, and the lower end of the feeding barrel being connected to a roller grinder through a hose; an insert plate is provided in the upper inner cavity of the feeding barrel, and the insert plate can be driven by a push-pull mechanism arranged outside the feeding barrel to slide back and forth in a horizontal direction to control the overlap or staggered state of the leakage hole opened in the middle of the insert plate and the inner cavity of the feeding barrel; an air inlet is provided on the lower barrel wall of the feeding barrel, and an air nozzle is installed in the air inlet for blowing the rollers that pass through the feeding barrel and the leakage hole and fall into the hose into the roller grinder.

[0005] Preferably, the loading cylinder includes a first cylinder and a second cylinder detachably connected to the bottom of the first cylinder, the insert plate is arranged in the first cylinder, and the air inlet is arranged on the second cylinder; a detachable feeding interface is provided at the upper end of the first cylinder.

[0006] Preferably, the push-pull mechanism is a hydraulic cylinder or an oil cylinder, and the inserting plate is detachably connected to the piston rod of the push-pull mechanism by bolts.

[0007] Preferably, the interior of the first cylinder has a slot for the inserting plate to slide back and forth, and the cylinder wall of the first cylinder has a socket for removing the inserting plate from the first cylinder.

[0008] Preferably, the second barrel and the feed interface are both detachably connected to the first barrel via a threaded structure.

[0009] Beneficial effects

[0010] The loading barrel of the present invention is provided with an insert plate. When the insert plate is acted upon by a push-pull mechanism so that the leakage hole in the middle thereof is connected with the inner cavity of the loading barrel, the tapered roller can be caused to fall from the material processing machine along the loading barrel and the leakage hole into the hose at the lower end position due to gravity. When the insert plate is acted upon by a push-pull mechanism so that the leakage hole and the inner cavity of the loading barrel intersect, the tapered roller in the hose can be blown into the grinder for fine processing through the high-pressure air introduced through the air nozzle.

[0011] The hose in this structure can bend appropriately due to pneumatic conveying, expanding the number of tapered rollers within the hose. This allows more tapered rollers to be fed into the grinder at once through the air nozzle. This shortens the distance between the feeder and the grinder, significantly reducing the feeder's installation height. This makes feeding the feeder easier and safer.

[0015] like Figure 1 As shown, the present invention provides a pneumatic tapered roller feeding device comprising a vertically distributed feeding barrel 1. The upper end of the feeding barrel 1 is connected to a roller feeder, and the lower end is connected to a roller grinder via a hose 2. The interior of the feeding barrel 1 is a vertical cavity into which the tapered rollers fall from the feeder into the hose 2 under their own gravity.

[0016] A plug plate 5 is provided in the upper inner cavity of the feeding barrel 1, and a leakage hole 6 is provided in the middle of the plug plate 5 for the tapered roller to pass through. A push-pull mechanism 4 such as a hydraulic cylinder or an air cylinder is provided outside the feeding barrel 1. The piston rod of the push-pull mechanism 4 is connected to the plug plate 5, so that the plug plate 5 is controlled to slide back and forth in the horizontal direction by the extension and contraction of the piston rod of the push-pull mechanism 4. Then, when the leakage hole 6 is controlled to move to a position concentric with the feeding barrel 1, as shown in FIG. Figure 1 As shown, the tapered roller located above the insert plate 5 in the inner cavity of the feeding barrel 1 can fall into the hose 2 through the leakage hole 6; after the leakage hole 6 is controlled to move to a staggered position with the inner cavity of the feeding barrel 1, as shown in FIG. Figure 2 As shown, the tapered roller located above the inserting plate 5 in the inner cavity of the loading cylinder 1 is prevented from continuing to fall.

[0017] An air inlet 3 is provided on the lower wall of the feeding barrel 1, and an air nozzle is installed in the air inlet 3. Figure 2 As shown, after the middle of the inner cavity of the loading barrel 1 is isolated by the insert plate 5, the rollers accumulated in the hose 2 can be blown into the roller grinder by the high-pressure air blown out from the air nozzle.

[0018] In a preferred embodiment of the present invention, the upper end of the loading barrel 1 is provided with a feed port 7 that communicates with its inner cavity and is used to receive tapered rollers from the material processing machine. The feed port 7, the leakage hole 6, the lower portion of the loading barrel 1, and the inner diameter of the hose 2 all correspond to the outer diameter of the tapered rollers to be transported and are smaller than the inner diameter of the upper portion of the loading barrel 1. This ensures precise conveying of the tapered rollers and prevents them from tumbling in this position, which could lead to a chaotic feeding posture. To make the present invention more adaptable in actual production and suitable for the feeding and conveying of tapered rollers of various specifications and sizes, the following technical solutions are adopted in this embodiment:

[0019] The loading barrel 1 includes a first barrel 101 and a second barrel 102 detachably connected to the bottom of the first barrel 101. The insert plate 5 is arranged in the first barrel 101, and the air inlet 3 is arranged on the second barrel 102. The second barrel 102 and the feed interface 7 are both detachably connected to the first barrel 101 with a threaded structure.

[0020] The first cylinder 101 has a socket on its wall for removing the plug plate 5 from the first cylinder 101 .

[0021] The inserting plate 5 is detachably connected to the piston rod of the push-pull mechanism 4 by means of bolts.

[0022] Through the above structure, when the material processing machine and the corresponding grinding machine switch to produce tapered rollers of different specifications, the feed interface 7, the insert plate 5 and the second cylinder 102 can be quickly removed from the first cylinder 101, retaining the original first cylinder 101 and the push-pull mechanism 4, and quickly replaced with the material interface, insert plate 5 and the second cylinder 102 with the same inner diameter.
