[0026] The present invention provides a hydraulic box turner for automatically turning over flasks and materials in an automated production line. The hydraulic box turner comprises at least: a fixed bracket 100; a turning frame 300; two turning cylinders 400; two flask clamping devices 600; and a material guide hopper 500. The hydraulic box turner can turn over only the flasks and materials in a continuous manner, with the clamping devices providing direct clamping. It features a simple structure, easy manufacture, low cost, stable performance, and ease of operation and maintenance.

[0027] Figure 1 This is a structural diagram of a hydraulic box turner according to an embodiment of the present invention. Figure 2 This is a side view of a hydraulic box turner according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the through-type hydraulic box tipping machine at least includes: a fixed bracket 100, which serves as the fixed part of the entire device and is used to firmly fix the entire equipment and support the turning frame; a turning frame 300, which is arranged on the fixed bracket 100; two turning cylinders 400, which are symmetrically arranged on the fixed bracket 100, and the two ends of each turning cylinder 400 are respectively connected to the turning frame 300 and the fixed bracket 100; two sand box clamping devices 600, which are symmetrically arranged on the turning frame 300, and each sand box clamping device 600 includes two guide rods 630 symmetrically arranged on the turning frame 300 and a clamping cylinder 640 arranged on the turning frame 300, and the clamping cylinder 640 drives the guide rod 630 to move up and down, thereby driving the sand box clamping device 600 to perform reciprocating motion.

[0028] The rotating shaft of the turnover frame 300 of the hydraulic carton turner of the present invention is connected to the fixed bracket 100 through the seat bearing 200. The turnover frame 300 is provided with a guide sleeve 310 that cooperates with the guide rod 630. The guide rod 630 can perform linear reciprocating motion along the guide sleeve 310.

[0029] Each tilting cylinder 400 in the hydraulic carton tipper of this embodiment includes a tilting cylinder head pin 410 and a tilting cylinder tail pin 420. Each tilting cylinder 400 is connected to the tilting frame 300 via the tilting cylinder head pin 410 and to the base plate of the fixed support 100 via the tilting cylinder tail pin 420. This hydraulic carton tipper independently rotates the carton tipper 300 through the relative motion between the piston rod and cylinder body of the tilting cylinder 400. The cylinder body of the clamping cylinder 640 is fixed to the tilting frame 300, and the top of the clamping cylinder 640 is connected to the upper support 640 via the clamping cylinder pin 641.

[0030] Each flask clamping device 600 of the hydraulic flask tipping machine according to the present invention further includes an upper bracket 610, the ends of which are connected to the upper ends of two guide rods 630, and a lower bracket 620, the ends of which are connected to the lower ends of the two guide rods 630. The upper bracket 610 and the lower bracket 620 are connected by the two guide rods 630 to form a square frame structure. The front flange of the clamping cylinder 640 of each flask clamping device 600 is bolted to the tipping frame 300. The top of the piston rod of the clamping cylinder 640 is connected to the upper bracket 610 via the clamping cylinder pin 641. Under the action of the clamping cylinder 640, the two guide rods 630 move back and forth linearly through the guide sleeve 310, thereby driving the flask clamping device 600 to move back and forth linearly. The sand box clamping device fits the sand box, logistics and turning frame together through the relative movement of the piston rod and cylinder body of the clamping cylinder, and turns over together with the turning frame to realize the box turning function.

[0031] The guide hopper 500 of the through-type hydraulic box tipper of the present invention is arranged on the tipping frame 300, and the guide hopper 500 is connected to the tipping frame 300 by bolts.

[0032] The through-type hydraulic box turner of the present invention further includes a flip limit block, which is arranged on the fixed bracket 100. The flip limit block is used in conjunction with the flip frame 300. When the flip frame 300 performs a flipping movement, the flip limit block limits the rotation angle of the flip frame 300 to prevent the flip frame 300 from over-flipping.

[0033] The above-mentioned through-type hydraulic box tipping machine of the utility model overcomes the technical problems that the existing self-tip box tipping machine needs to be turned together with the transfer track or conveying device, and the clamping mechanism is tightly clamped by a connecting rod mechanism, which is prone to malfunction, has a complex structure, high cost, is difficult to repair when a malfunction occurs, and requires a high level of technical skills of the workers; it has the characteristics of simple structure, easy production, stable performance, high flexibility, and high efficiency, and has great promotion value.

[0034] refer to Figure 3 As shown, the working principle of the through-type hydraulic box tipping machine of the present invention is as follows: the sand box filled with materials is transported to the fixed support 100 and below the turning frame 300, and the cylinder rods of the clamping cylinders 640 in the symmetrically arranged sand box clamping device 600 are all extended. Driven by the guide rod 630, the lower support 620 of the sand box clamping device 600 rises, and the sand box and the turning frame 300 are fitted and clamped; the cylinder rods of the two turning cylinders 400 are extended to push the turning frame 300 to turn over; when the turning frame 300 is turned to the working position, the material in the sand box is poured out through the guide hopper 500, completing the turning action; the cylinder rod of the turning cylinder 400 is retracted, driving the turning frame 300 to turn over and return to its original position; at this time, the cylinder rods of the clamping cylinders 640 of the sand box clamping device 600 are retracted, and the completed turning sand box is placed back on the fixed support 100, and then the sand box is transported out of the fixed support 100.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention.
