Description

Technical Field

[0001] The utility model relates to a can cover conveying mechanism for a drying furnace. Background Art

[0002] Canning is a method of packaging food. The packaging material is tinplate. The can opener uses a can opener, or there is imitation can technology, the packaging material used is aluminum alloy. Nowadays, most can opening methods are can type, which is easy to use.

[0003] The closing lid of the can (can lid) is generally made of tinplate or aluminum in the current industry, and drying equipment is required during the production process.

[0004] However, the new type of can lid in the prior art moves into the drying oven in a way that the rear cover wheel continuously turns over the new cover and pushes it to move slowly, which causes friction between the covers, resulting in scratches and peeling of the paint on the surface of the can lid, and the conveying component only provides support by itself, resulting in the problem of weak conveying stability; at the same time, during the stacking and pushing process of the can lids, the can lids may bulge out due to squeezing, so the direct drying operation will affect the quality of the finished product and the pushing in this case may cause collision and tipping, and continuing to convey without an alarm after tipping may cause tipping in a larger range, which will also affect the quality of the finished product and may cause safety hazards, which needs to be improved urgently.

A V-shaped sensing rod is rotatably connected to the outer wall of the drying furnace. The V-shaped bottom of the sensing rod overlaps the top of the can cover, and a sensor is arranged above the other end and docked with the sensor. The sensor is fixed to the outer wall of the drying furnace via a fixing plate.

[0010] Furthermore, one end of the sensing rod is rotatably connected to the outer wall of the drying furnace via a hinge, one side of the hinge is fixed to the outer wall of the drying furnace, and the other side is welded and fixed to the sensing rod.

DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figures 1 to 3 As shown, the can cover conveying mechanism for the drying furnace includes can covers 1 stacked and conveyed front and back and a support frame 2 supported at the lower end of the can cover, the support frames are arc-shaped and symmetrically supported on both sides of the bottom of the can cover and a clearance push port 3 is opened at the bottom, and an auxiliary push belt 4 for supporting and pushing the can cover is arranged in the clearance push port.

[0022] In the embodiment of the utility model, a can cover conveyor belt 5 is provided at the can cover input end, and a turning wheel assembly 6 for turning the horizontally conveyed can covers to vertical and stacking them is arranged between the can cover conveyor belt and the support frame.

[0023] In the embodiment of the utility model, the flip wheel assembly includes two rubber rollers 7, and the relative end faces of the two rubber rollers are both concave arc surfaces to match the arc surfaces on both sides of the end cover. Block magnets 8 are embedded in the relative end faces of the rubber rollers. The two rubber rollers are coaxially rotated through a rotating shaft 9, and one end of the rotating shaft is driven to rotate by a motor 10. The block magnet is coaxially arranged with the rubber roller to ensure that the rubber roller can maintain the state of the end cover when it rotates to any angle, that is, it can rotate with the rotation of the rubber roller to swing the end cover from the original horizontal state to the vertical.

[0024] In the embodiment of the utility model, the can covers are transported to the drying furnace 11 along the support frame and the auxiliary push belt. A V-shaped sensing rod 12 is rotatably connected to the outer wall of the drying furnace. The V-shaped bottom of the sensing rod is overlapped on the top of the can cover, and a sensor 13 is arranged above the other end and docked with it. The sensor is fixed to the outer wall of the drying furnace through a fixing plate 14. When the can cover is tilted or tilted, a large gap is generated between adjacent can covers. The sensing rod will fall freely into the gap, causing the sensing rod to leave the sensing range of the sensor. At this time, the sensor will transmit the signal and stop the device from running, ensuring safety and stable transportation of the can cover.

[0025] In the embodiment of the utility model, one end of the sensing rod is rotatably connected to the outer wall of the drying oven via a hinge 15, one side of the hinge is fixed to the outer wall of the drying oven, and the other side is welded and fixed to the sensing rod.

[0026] In the embodiment of the utility model, a horizontal seat 16 is fixedly provided on the outer wall of the drying furnace, and a turning handle 23 is hinged on both sides of the outer end of the horizontal seat. A shaping pressing wheel 17 is rotatably connected between the two turning handles. The shaping pressing wheel is pressed on the top of the can cover to help press the extruded protruding can cover back, thereby ensuring the stability of the stacking shape of the can cover.

[0027] In the embodiment of the utility model, shaping side wheels 18 that rotate as the can cover is pushed are symmetrically arranged on both sides of the support frame between the auxiliary pushing belt and the flip wheel assembly. The shaping side wheels are provided with arc grooves 19 that are recessed from the outside to the inside to match the arc side edges of the can cover. The support frame is provided with a clearance opening 20 for the shaping side wheels to be placed. The shaping side wheels return the protruding sides on both sides when the can covers are stacked to ensure the stability of the stacked shape of the can covers.

[0028] In the embodiment of the utility model, the shaping side wheel is installed on the main engine seat 21 via a bearing seat, and the main engine seat is provided with a strip groove 22 for adjusting and fixing the bearing seat, and the lower end of the support frame is fixed on the main engine seat.

[0029] The working principle of the embodiment of the utility model is as follows: first, the can covers are transported to the turning wheel assembly at intervals via the can cover conveyor belt and adsorbed via the block magnet; as the rubber roller rotates, the can covers are turned vertically and stacked by inertia and the subsequent pushing of the can covers; the front can covers are assisted in pushing by the auxiliary pushing belt, which effectively avoids damage caused by mutual friction between the can covers caused by only pushing by the rotating, squeezing and pushing of the rubber roller; the rear can covers are shaped by the shaping side wheels and the shaping pressure wheels in turn to ensure a stable conveying shape; finally, they are all assisted in pushing to the drying furnace for drying by the auxiliary pushing belt, which also runs through the entire drying and conveying process to avoid push jams or damage to the can covers.

[0030] The present invention is not limited to the above-mentioned best implementation mode. Anyone can derive other forms of can cover conveying mechanisms for drying furnaces under the inspiration of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
