DETAILED DESCRIPTION

[0018] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0019] A raw material crushing device for producing foam packaging boxes comprises a crushing barrel 1 with a discharge pipe 14 at the bottom, wherein a rotating shaft 3 driven by a motor 12 is arranged in the crushing barrel 1, and a crushing rod 4 is arranged on the rotating shaft 3:

[0020] It also includes a base 5 located directly below the crushing barrel 1, wherein both sides of the base 5 are provided with vertical plates 6 located outside the crushing barrel 1, and the two side walls of the crushing barrel 1 are provided with rotating shafts that pass through the corresponding vertical plates 6 and are driven by a motor II7, and the vertical plates 6 on both sides of the crushing barrel 1 are vertically provided with strip openings 8, wherein a plurality of groups of strip openings 8 are provided with limiting mechanisms 9, and the limiting mechanisms 9 include a transverse plate 91 located outside the vertical plate 6, wherein the corresponding top ends of two groups of transverse plates 91 are connected by limiting rods 92, and the limiting rods 92 pass through the corresponding two groups of strip openings 8 on the same side, and a convex seat 93 is provided on the outer wall of the vertical plate 6 above the transverse plate 91, wherein a screw I94 connected to the transverse plate 91 through a bearing 95 is screwed on the convex seat 93;

[0021] A jacket 10 is provided at the bottom of the crushing barrel 1, wherein an air inlet pipe 11 is provided on the jacket 10, and air outlet holes with a diameter not greater than 0.2 cm are evenly provided on the bottom wall of the crushing barrel 1 in the jacket 10.

[0022] In this embodiment, a feed pipe 12 and an exhaust pipe 13 are arranged on the cover plate of the crushing barrel 1 , a slag discharge pipe 15 is arranged on the side wall of the jacket 10 for discharging fine materials that may exist in the jacket 10 , and the bottom end of the discharge pipe 14 passes through the side wall of the jacket 10 .

[0023] like Figure 2 As shown, a flow deflector 17 is connected to the bottom of the discharge pipe 14 through a corrugated hose 16, wherein the flow deflector 17 is fixed on a screw II18 located between two sets of vertical plates 6, and a screw hole for the screw II18 to pass through is provided on the vertical plate 6. When the crushing barrel 1 swings back and forth, it will pull the corrugated hose 16 to shrink and stretch, so that it will not affect the swinging work of the crushing barrel 1, and at the same time, by opening the discharge pipe 14, the material in the crushing barrel 1 can be discharged through the discharge pipe 14, the corrugated hose 16 and the flow deflector 17. In the above process, the screw II18 can fix the flow deflector 17, and at the same time, the screw II18 can be rotated to rotate in the screw hole, thereby driving the flow deflector 17 to change its direction and tilt angle.

[0024] In this embodiment, the number of bosses 93 on each group of vertical plates 6 is not less than two groups, wherein the number of screw rods 194 is equal to the number of bosses 93, and the bosses 93 are provided with screw tubes 19 threadedly connected to the screw rods 194, wherein a driving block is provided at the top of the screw rods 194.

[0025] In this embodiment, a rectangular notch 20 is disposed at one end of the base 5 and is located between the two groups of vertical plates 6 , wherein a material collecting box 21 is disposed in the rectangular notch 20 for receiving the raw materials discharged from the deflector 17 .

[0026] The method of using the present invention is as follows: the motor I2 drives the rotating shaft 3 to drive the crushing rod 4 to crush the material in the crushing barrel 1, wherein the motor II7 can drive the rotating shaft to drive the crushing barrel 1 to swing back and forth to shake the internal material, so that the material can fully contact the crushing rod 4 and be fully crushed. At the same time, a strong air flow can be introduced into the jacket 10 through the air inlet pipe 11, and then sprayed into the crushing barrel 1 through a number of air outlets to play a certain blowing effect on the lighter raw materials, so that the raw materials can roll in the crushing barrel 1 to facilitate the crushing rod 4 to crush them.

[0027] In the above process, the limit rods 92 on the left and right sides can limit the swinging amplitude of the crushing barrel 1. When the crushing barrel 1 contacts a limit rod 92, the motor II7 drives the crushing barrel 1 to swing in the other direction, so as to limit the swing amplitude of the crushing barrel 1. In order to increase the swing amplitude of the crushing barrel 1, the screw rod I94 can be rotated upward to rotate in the screw tube 19 and the bearing 95, while driving the cross plate 91 to drive the limit rod 92 to move upward in the strip opening 8. At this time, only when the swing amplitude of the crushing barrel 1 increases will it contact the corresponding limit rod 92, and the step of reducing the swing amplitude of the crushing barrel 1 is just the opposite, so as to limit the swing amplitude of the crushing barrel 1 through the limit mechanism 9.

[0028] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
