The working principle of the invention is as follows:

with continued reference to fig. 1 to 5, in the present embodiment, the device is applied to a high-temperature tunnel furnace 9, and the translation driving mechanism 7 includes a translation guide rail module arranged in a U shape, a drag chain assembly and a motor for driving the drag chain assembly to operate; the translation guide rail module is arranged in the tunnel furnace, and two U-shaped vertical ends of the translation guide rail module penetrate out of the tunnel furnace; the end parts of two U-shaped vertical ends of the translation guide rail module are respectively a feeding end and a discharging end, and the motor is arranged outside the tunnel furnace, so that the product can be continuously conveyed into the tunnel furnace for processing, and then the processed product is conveyed out of the tunnel furnace for blanking; in this embodiment, one side of the sliding seat 8 is further provided with a limiting wheel, and the sliding seat 8 is slidably arranged on the translational guide rail module through the limiting wheel, so that the sliding stability of the sliding seat can be ensured; the other side of the sliding seat 8 is also provided with a fixing clamp 81, and the fixed seat 3 can be detachably arranged on the sliding seat 8 through the fixing clamp 81, so that the disassembly and assembly are convenient, and the placement and the removal of products are convenient; go up slope guide rail 1 and slope guide rail 2 arrange in the tunnel furnace down, interval between the two is adjustable, can freely set up according to user demand (the distance that makes the product keep the horizontality), compares in traditional drive mode who adopts motor or cylinder, and the device is convenient for adjust the product and need the distance that removes under the horizontality, and is convenient high-efficient, concrete during operation:

firstly, clamping and fixing the product through the rotating clamp 42, and installing the fixed seat 3 on the sliding seat 8 through the fixing clamp 81, wherein initially, the clamping plate 41 of the clamping assembly 4 and the product are both in a vertical state; then, the translation driving mechanism 7 drives the fixed seat 3 to drive the product to translate into the tunnel furnace, and the product is always in a vertical state before passing through the upper slope guide rail 1; then, the fixed seat 3 reaches the inlet of the upper slope guide rail 1, under the driving of the translation driving mechanism 7, the sliding wheel 63 of the upper guide wheel shaft 61 rises along the inner wall inclined plane of the guide cavity, and the sliding wheel 63 of the lower guide wheel shaft 62 abuts against the bottom wall of the guide rail shell 11 to guide the guide rail shell, so that the rolling stability is ensured; the lifting guide rod 51 penetrates through the guide chute 12 and continues to translate forwards, and along with the upward rolling of the sliding wheel 63 of the upper guide wheel shaft 61, the lifting guide rod 51 is driven to move upwards, and then the lifting guide rod 51 drives the clamping plate 41 and the product to slowly rotate upwards through the lifting rotating block 52, when the sliding wheel 63 rolls to the outlet of the upper slope guide rail 1, the clamping plate 41 drives the product to turn over by 90 degrees, and at the moment, the product turns over from a vertical state to a horizontal state; in addition, in the ascending motion process of lift guide bar 51, also can drive magnet mount pad 54 and do synchronous rising motion, when the movable pulley 63 of last leading wheel axle 61 rolls to the exit of supreme slope guide rail 1, magnet assembly 55 of magnet mount pad 54 adsorbs together with the guide block 32 that adopts the magnetism material to make just, under the effect of magnetic attraction, the product can continue to keep for the horizontality, and then do not need to set up any supporting mechanism in the region between last slope guide rail 1 and the lower slope guide rail 2, can make the product keep the horizontality throughout in arbitrary distance, convenient and practical.

Under the drive of the translation driving mechanism 7, the product horizontally moves for a certain distance and then reaches the inlet of the lower slope guide rail 2; at this time, the sliding wheel 63 of the upper guide wheel shaft 61 enters into the guide cavity of the lower slope guide rail 2, the inner wall of the top of the guide cavity presses the sliding wheel 63, thereby driving the lifting guide rod 51 to descend, and in the descending process of the lifting guide rod 51, the magnet assembly 55 is driven to gradually separate from the guide block 32, thereby driving the clamping plate 41 and the product to slowly rotate downwards for resetting, when the sliding wheel 63 slides out of the exit of the lower ramp 2, the clamping plate 41 is just turned back down by 90 °, so that the product returns to the original vertical position, the translation motion is continued along the translation guide rail module under the driving of the translation driving mechanism 7 until the discharging flows out of the tunnel furnace, which is convenient and practical, compared with the conventional mode of turning over by adopting an air cylinder, a motor and the like, the device can greatly reduce the cost, is suitable for the severe environment with narrow space and has strong universality.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
