DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Reference Figure 1-Figure 4 The hot-rolled steel plate production processing device with automatic unloading function shown in the figure comprises a mounting plate 1, side plates 2 are fixedly mounted on both sides of the mounting plate 1, two fixed plates 4 are arranged between the two side plates 2, sliding holes are opened on the tops of the two fixed plates 4, blocking holes connected to the sliding holes are opened on the sides of the two fixed plates 4, upper baffles 10 and lower baffles 12 are slidably mounted in the two blocking holes, an upper unloading hole 11 corresponding to the sliding hole is opened on the top of the upper baffle 10, and a lower unloading hole 13 is opened on the top of the lower baffle 12, two connecting columns 3 are fixedly mounted on the sides of the two fixed plates 4, and the ends of the four connecting columns 3 away from the fixed plates 4 are respectively fixedly mounted on the sides of the two side plates 2 close to each other, and the two side A heating block 5 is provided between the plates 2. A circular hole is provided on the top of the heating block 5. An intermediate tube 6 and a lower tube 7 are fixedly installed on the top and bottom of the heating block 5 respectively. The top end of the intermediate tube 6 extends to the upper sliding hole, and the bottom end of the lower tube 7 extends to the lower sliding hole. A feed hopper 8 is provided above the heating block 5. A connected upper tube 9 is fixedly installed on the bottom of the feed hopper 8. The bottom end of the upper tube 9 extends to the upper sliding hole. A moving mechanism is installed on the side of one of the side plates 2. An upper pressure mechanism is installed on the side of the feed hopper 8. A lower pressure mechanism is installed on the side of the heating block 5. The moving mechanism is installed in cooperation with the lower pressure mechanism and the upper pressure mechanism. An annular cavity is provided on the heating block 5, and a heating coil 30 is fixedly installed on the inner wall of the annular cavity. Figure 2 As shown, the upper tube 9 and the middle tube 6 are located on both sides of the upper baffle 10, the upper tube 9 can slide upward in the upper sliding hole, the middle tube 6 can slide downward in the upper sliding hole, and the lower tube 7 can slide downward in the lower sliding hole.

[0021] The moving mechanism includes a telescopic cylinder 29 fixedly mounted on the side of the side plate 2, a U-shaped rod 16 fixedly mounted on the output end of the telescopic cylinder 29, an upper connecting rod 14 and a lower connecting rod 15 fixedly mounted on the side of the U-shaped rod 16, two through holes are provided on the side of the mounting plate 1, and the ends of the upper connecting rod 14 and the lower connecting rod 15 away from the U-shaped rod 16 respectively pass through the two through holes and are fixedly connected to the sides of the upper baffle 10 and the lower baffle 12 respectively.

[0022] By means of the above structure: when in use, the steel billet is put in through the feed hopper 8. Since the upper discharge hole 11 corresponds to the upper tube 9, the steel billet can enter the circular hole through the upper discharge hole 11. The steel billet is located above the lower baffle 12. By starting the telescopic cylinder 29, the U-shaped rod 16 can be close to the side plate 2, thereby driving the upper connecting rod 14 and the lower connecting rod 15 to move, thereby moving the upper baffle 10 and the lower baffle 12. The upper discharge hole 11 on the upper baffle 10 is staggered with the upper sliding hole, so that no feeding is performed. At this time, the lower discharge hole 13 is staggered with the lower sliding hole, and the material cannot be discharged. Then, preheating can be performed by starting the heating coil 30. After the preheating is completed, the output end of the telescopic cylinder 29 continues to contract so that the lower discharge hole 13 below corresponds to the lower sliding hole. At this time, the material can be discharged. The feed hopper 8 is driven to move back and forth by the moving mechanism during feeding, thereby reducing blockage and facilitating automatic feeding. The heating block 5 is driven to move back and forth during discharging, thereby reducing blockage and facilitating automatic feeding.

[0023] The moving mechanism includes a motor 23 fixedly mounted on the side of the U-shaped rod 16, a fixed shaft 24 fixedly mounted on the output end of the motor 23, a cam 25 slidably sleeved on the fixed shaft 24, a reset block 28 fixedly mounted on the end of the fixed shaft 24 away from the motor 23, two reset holes are provided on the side of the cam 25, two reset rods 26 are fixedly mounted on the side of the reset block 28, the two reset rods 26 respectively penetrate the two reset holes, and reset springs 27 are sleeved on the two reset rods 26, and the two ends of the reset spring 27 are respectively fixedly mounted on the sides of the cam 25 and the reset block 28 close to each other. During the movement of the motor 23, if the cam 25 does not correspond to the position of the upper pressing plate 18 or the lower pressing plate 21, the cam 25 will move and the reset spring 27 will be deformed. When the cam 25 corresponds to the upper pressing plate 18 or the lower pressing plate 21 during the rotation process, the cam 25 is restored to its original state under the action of the reset spring 27, so as to avoid and align with the upper pressing plate 18 or the lower pressing plate 21.

[0024] The upper pressure mechanism includes two upper L-shaped rods 17. Two upper moving holes are opened on the side of the mounting plate 1. The two upper L-shaped rods 17 are slidably installed in the two upper moving holes respectively. Upper moving rods are fixedly installed on the top inner walls of the two upper moving holes. Upper guide holes are opened on the tops of the two upper L-shaped rods 17. The bottom ends of the two upper moving rods respectively penetrate the two upper guide holes and are fixedly installed on the bottom inner walls of the two upper moving holes respectively. An upper spring 20 is sleeved on the upper moving rod. The two ends of the upper spring 20 are fixedly installed on the top inner wall of the upper moving hole and the top of the upper L-shaped rod 17 respectively. An upper pressure plate 18 is fixedly installed on the bottom ends of the two upper L-shaped rods 17. The bottom of the upper pressure plate 18 contacts the side of the cam 25. Start the motor 23, and the output end of the motor 23 rotates to drive the fixed shaft 24 and the cam 25 to rotate. When the cam 25 rotates, it squeezes the upper pressure plate 18 to make the two upper L-shaped rods 17 move up, thereby causing the two upper springs 20 to deform. When the cam 25 does not squeeze the upper pressure plate 18, the upper L-shaped rods 17 move down under the action of the upper springs 20, thereby causing the feed hopper 8 to reciprocate up and down first, thereby facilitating unloading.

[0025] The lower pressure mechanism includes two lower L-shaped rods 19. Two lower moving holes are opened on the side of the mounting plate 1. The two lower L-shaped rods 19 are slidably installed in the two lower moving holes respectively. Lower moving rods are fixedly installed on the top inner walls of the two lower moving holes. Lower guide holes are opened on the tops of the two lower L-shaped rods 19. The bottom ends of the two lower moving rods respectively pass through the two lower guide holes and are fixedly installed on the bottom inner walls of the two lower moving holes respectively. A lower spring 22 is sleeved on the lower moving rod. The two ends of the lower spring 22 are respectively fixedly installed on the bottom inner wall of the lower moving hole and the bottom of the lower L-shaped rod 19. A lower pressure plate 21 is fixedly installed on the top of the two lower L-shaped rods 19. The position of the lower pressure plate 21 corresponds to that of the cam 25. After preheating is completed, the output end of the telescopic cylinder 29 continues to contract so that the lower discharge hole 13 below corresponds to the lower sliding hole. At this time, the material can be discharged. At the same time, the motor 23 also moves to move the cam 25. The cam 25 corresponds to the position of the lower pressure plate 21. When the cam 25 rotates, it cooperates with the lower spring 22 to make the lower pressure plate 21 move back and forth first down and then up, so that the heating block 5 is moved first down and then up, which is convenient for discharging.
