DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figures 1-3 , a fast and efficient gate shearing device includes a base 1. A shearing groove 2 is formed in the top of the base 1. An auxiliary groove 22 communicating with the shearing groove 2 is formed in one side of the base 1. A fixed placement plate 3 is fixedly connected between the inner walls on both sides of the shearing groove 2. A first threaded rod 5 is penetrated through and threadedly connected to the inner wall at one end of the shearing groove 2. A first knob 6 is fixedly installed at the end of the first threaded rod 5 outside the shearing groove 2. One end of the first threaded rod 5 located inside the shearing groove 2 is rotatably connected to a movable placement plate 4. The movable placement plate 4 is slidably connected to the inner walls on both sides of the shearing groove 2. A shearing mechanism is arranged above the base 1.

[0020] The shearing mechanism includes four support rods 9 fixedly installed on the top of the base 1. The same top plate 11 is fixedly installed at the tops of the four support rods 9. Two first cylinders 13 are fixedly installed at the bottom of the top plate 11. The same shearing plate 12 is fixedly installed at the telescopic ends of the two first cylinders 13. An adjustment groove 14 is formed in the shearing plate 12. A second threaded rod 8 is penetrated through and threadedly connected to the inner wall at one end of the adjustment groove 14. A second knob 7 is fixedly installed at the end of the second threaded rod 8 outside the adjustment groove 14. One end of the second threaded rod 8 located inside the adjustment groove 14 is rotatably connected to an adjustment block 15 that is slidably connected to the inner walls on both sides of the adjustment groove 14. Installation frames 16 are fixedly installed at the bottoms of the shearing plate 12 and the adjustment block 15. Installation rods 24 are penetrated through and slidably connected to one side wall of the two installation frames 16. Connecting blocks 26 are fixedly installed at the ends of the two installation rods 24 outside the corresponding installation frames 16. A tension spring 25 is fixedly connected between the connecting block 26 and the installation frame 16. Blades 17 are arranged inside the installation frames 16. Installation grooves 23 are formed in the blades 17. The installation rods 24 are adapted to the installation grooves 23. The cross-section of the installation rod 24 is in the shape of a right trapezoid.

[0021] A collection mechanism is arranged below the shearing groove 2. The collection mechanism includes a support plate 18 rotatably connected to the inner wall at one end of the auxiliary groove 22. A second cylinder 21 is fixedly installed on the inner wall at one end of the auxiliary groove 22. A slider 20 slidably connected to the bottom inside the auxiliary groove 22 is fixedly installed at the telescopic end of the second cylinder 21. One end of a connecting rod 19 is rotatably connected to the top of the slider 20. The other end of the connecting rod 19 is rotatably connected to the bottom of the support plate 18. A collection box 10 is arranged on one side of the base 1.

[0022] When the utility model is in use, first, hold the plastic product to be sheared and place it in the shearing groove 2, and align the sprue on the plastic product to be sheared and place it in the upper notches of the fixed mounting plate 3 and the movable mounting plate 4. The support plate 18 can support the plastic product. Then, rotate the first knob 6 to make the first threaded rod 5 rotate. Since the movable mounting plate 4 is slidably connected to the inner walls on both sides of the shearing groove 2 and will not rotate while the first threaded rod 5 is rotationally connected to the movable mounting plate 4, the movable mounting plate 4 can be translated left and right, which is convenient for precise adjustment according to the length of the sprue. By rotating the second knob 7, the second threaded rod 8 rotates. The rotation of the second threaded rod 8 makes the adjusting block 15 translate left and right in the adjusting groove 14, and then makes one mounting frame 16 and one blade 17 move left and right, which is convenient for cutting according to the length of the sprue. Finally, the first cylinder 13 makes the shearing plate 12 and the two blades 17 move downward, so as to cut both ends of the sprue simultaneously by the two blades 17. The cut waste will fall onto the support plate 18;

[0023] After cutting is completed, the first cylinder 13 makes the shearing plate 12 and the two blades 17 move upward. Then, the second cylinder 21 makes the slider 20 (in the attached Figure 2 state) slide to the left. By setting the connecting rod 19, the support plate 18 deflects, and then the waste on the support plate 18 slides into the collection box 10. By pulling the connecting block 26 away from the mounting frame 16, the tension spring 25 can be stretched, and the mounting rod 24 will move out of the mounting groove 23 of the blade 17, so that the blade 17 can be removed. When installing, insert the blade 17 into the mounting frame 16. The top end of the blade 17 will contact the inclined surface on the mounting rod 24, and then the mounting rod 24 can move outward automatically, and the tension spring 25 is stretched. Finally, as the blade 17 continues to move upward, the mounting rod 24 can be automatically inserted into the mounting groove 23 to realize the installation of the blade 17.

[0024] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the utility model.
