Detailed Embodiments

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] An inertia block screening mechanism, as Figure 1-2As shown in the figure, it includes a material channel 1, a go-no-go gauge 2, an opening and closing part 3, and a connecting part 4. The go-no-go gauge 2 is used to detect the size of the inertia block. That is, when the inertia block can pass through the go-no-go gauge 2 in a specific posture, it indicates that the size of the inertia block meets the standard; otherwise, the inertia block will be stuck at the go-no-go gauge 2 and cannot pass through. Among them, the material channel 1 is arranged obliquely so that the inertia block can slide down smoothly without the need for additional driving force; the go-no-go gauge 2 is arranged at the lower end of the material channel 1 to detect the size of the inertia block. A first guide rod 5 is also arranged in the channel of the material channel 1. There are two first guide rods 5, and the two first guide rods 5 are arranged at intervals along the traveling route of the inertia block. The interval between the two first guide rods 5 is used to guide the counterweight of the inertia block, and the interval between the first guide rod 5 and the side wall of the material channel 1 guides the pawl of the inertia block. Furthermore, through the cooperation of the first guide rod 5 and the material channel 1, the inertia block moves while maintaining its posture. The opening and closing part 3 is arranged at the entrance end of the go-no-go gauge 2. When the go-no-go gauge 2 jams the material, the jammed inertia block is taken out by opening the opening and closing part 3 to make the equipment resume normal operation. Specifically, one end of the opening and closing part 3 is hinged to the material channel, and a first lock hole 31 is arranged at the other end. A second lock hole 11 is arranged on the material channel 1. The first lock hole 31 and the second lock hole 11 are connected by the connecting part 4 so that the opening and closing part 3 remains in a locked state.

[0021] In one embodiment, as shown in FIGS. 1-2, the opening and closing part 3 includes a hinge seat 32, a hinge shaft 33, and a hinge arm 34. The hinge seat 32 is fixed on one side of the material channel 1. One end of the hinge arm 34 is hinged to the hinge seat 32 through the hinge shaft 33, and a first lock hole 31 is arranged at the other end of the hinge arm 34.

[0022] In the above embodiment, as shown in FIGS. 1-2, a second guide rod 35 is arranged on the hinge arm 34. When the opening and closing part 3 is locked, the second guide rod 35 is arranged at the extended position of the first guide rod 5. The inertia block is always kept in a specific posture through the second guide rod 35.

[0023] In one embodiment, as shown in FIGS. 1-2, the connecting part 4 includes a first rod part 41 and a second rod part 42. The first rod part 41 is arranged on the second rod part 42, and the second rod part 42 and the first rod part 41 form a stepped structure. Preferably, the diameter of the second rod part 42 is matched with the first lock hole 31 and the second lock hole 11.

[0024] In the above embodiment, as shown in FIGS. 1-2, the end of the second rod part 42 is a pointed part. This pointed part has two functions. One is to set the end of the second rod part 42 as a pointed part, and the overall diameter changes from small to large. The pointed part guides the second rod part 42 to smoothly enter the first lock hole 31 and the second lock hole 11. The other is that when the opening and closing part 3 is opened, the connecting part 4 needs to be removed. Therefore, the staff can directly use the end of the connecting part to take out the jammed inertia block, which is convenient for operation. At the same time, because the connecting part is always in a used state, it will not be placed randomly and will not be easily lost.

[0025] In one embodiment, as Figure 1-3 shown, both the first keyhole 31 and the second keyhole 11 are inclined holes; when the opening and closing member 3 is locked, the first keyhole 31 is located at the axial extension of the second keyhole 11. That is, an angle is provided between the axis of the second keyhole 11 and the axis of the hinge shaft 33. As Figure 3 shown, Figure 3 the arrow direction in

[0026] is the opening direction of the hinge arm 34. By setting an angle between the opening direction of the hinge arm 34 and the axis of the connecting member 4, the hinge arm 34 is locked through the connecting member 4.

[0027] The above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention; if the present invention is modified or equivalently replaced without departing from the spirit and scope of the present invention, it shall be covered by the protection scope of the claims of the present invention.
