[0002] A mosquito repellent is a substance containing a drug that, when burned, produces smoke that can repel or kill mosquitoes. my country has a very long history of using mosquito coils. Traditional mosquito coils are divided into two types: stick incense and coil incense. When preparing mosquito coils, the raw materials need to be screened in advance to separate the impurities.

[0003] According to the search results on the China Patent website, a raw material screening device for mosquito coil preparation with application number 202222644751.X is found. This screening device uses a sieve plate, a servo motor, and a lever to screen and remove impurities from the mosquito coil raw materials.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7A raw material screening device for the preparation of green mosquito coils includes a separation cylinder 1, a fixed rod 2 connected to the upper end of the separation cylinder 1, a servo motor 3 fixedly connected to one end of the fixed rod 2, and a lever 4 arrayed at one end of the output shaft of the servo motor 3. A screening plate 5 is slidably inserted into the inner wall of the separation cylinder 1. A slot is formed on the surface of the cylinder body of the separation cylinder 1, and a plate changing mechanism 6 is slidably connected to the inner wall of the slot. A semi-circular sliding groove 60 is formed inside the cylinder of the separation cylinder 1, and spring grooves 61 are arrayed on the bottom wall of the sliding groove 60. The spring grooves 61 are divided into upper and lower sections. Two parts: a wire rope groove 62 is formed on the inner bottom wall of one side of the slide 60; a matching limiting plate 63 is slidably connected to the surface of the slide 60; a spring I64 is fixedly connected to the upper inner wall of each spring groove 61; the upper end of each spring I64 is fixedly connected to the lower end of the limiting plate 63; a connecting rod 65 is slidably sleeved on the surface of each spring I64; the upper end of each connecting rod 65 is fixedly connected to the lower end of the limiting plate 63; the lower ends of two connecting rods 65 located symmetrically near the limiting plate 63 are fixedly connected... A crossbar 66 is connected, and a push rod 67 is fixedly connected at the middle position of the crossbar 66. A tensioning mechanism 68 is provided inside the wire rope groove 62. The tensioning mechanism 68 includes an I-shaped push block 681. A spring II 682 is fixedly connected to one side of the push block 681. One end of the spring II 682 is fixedly connected to the inner wall of the spring groove 61. The lower end of the push block 681 is slidably connected to the inner wall of the groove. One end of the push block 681 is in contact with one side of the screening plate 5. A wire rope 683 is fixedly connected to the other end of the push block 681. The wire rope groove... The inner wall of 62 is provided with multiple fixed pulleys 684. One end of the wire rope 683 is fixedly connected to a fixed column 685. The surface of the wire rope 683 is slidably connected to the surface of each fixed pulley 684. The lower end of the fixed column 685 is slidably connected to the lower inner wall of the spring groove 61 through a spring. The upper end of the limiting plate 63 is provided with a slot. One end of the screening plate 5 is fixedly connected to a locking block, which is engaged with the inner wall of the slot. The lowering height of the connecting rod 65 is the same as the lowering height of the limiting plate 63 and the stretching length of the wire rope 683.

[0025] Specifically, the plate changing mechanism 6 uses a slot on the surface of the separating cylinder 1, and a locking block fixedly connected to one end of the screening plate 5 can engage with the inner wall of the groove on the upper end of the limiting plate 63. This engagement method allows the screening plate 5 to be quickly and accurately positioned and fixed in the appropriate location during installation. When the screening plate 5 needs to be replaced, simply release the locking block from the groove to easily pull the screening plate 5 out of the separating cylinder 1. This greatly improves the speed and convenience of replacing the screening plate 5, reduces downtime during equipment maintenance and component replacement, and helps improve the efficiency of the entire green mosquito coil production process. The locking relationship of the slot requires pulling the push rod 67 downward. When the limiting plate 63 is fully retracted into the slide groove 60, the locking relationship between the locking block and the slot is released. However, it is still inconvenient to remove it. In order to further facilitate the removal of the screening plate 5, the tensioning mechanism 68, during the continuous descent of the push rod 67, squeezes the fixed column 685, thereby pulling the wire rope 683 to drive the I-shaped push block 681 to push the screening plate 5 outward. When the push rod 67 descends to its maximum height, the locking block is fully exposed on the outside. The operator only needs to gently pull out the screening plate 5, which further improves the efficiency of replacing the screening plate 5.

[0026] In this embodiment, the inner wall of the slot is coated with a lubricating coating; specifically, this makes it easier to replace the screening plate 5 and reduces friction between the inner wall of the slot and the surface of the screening plate 5.

[0027] Operating principle:

[0028] When replacing the screening plate, the operator pushes the push rod 67 downwards, and the crossbar 66 pulls the limiting plate 63, which is fixedly connected to the connecting rod 65, down until the limiting plate 63 is completely retracted into the slide groove 60. Then, the push rod 67 is continuously pushed down, and the lower end of the push rod 67 contacts the fixed column 685 and squeezes it. The squeezed fixed column 685 pulls the wire rope 683, and the other end of the wire rope 683 pulls the push block 681 to move outwards. The push block 681 pushes the screening plate 5 out of the slot. The operator takes out the screening plate 5 and replaces it with another screening plate 5. When the other screening plate 5 is inserted into the slot, it squeezes the push block 681. At this time, the push rod 67 can be released until the other screening plate 5 is fully inserted into the slot. The limiting plate 63 returns to its original shape under the action of the spring 164, and the locking block on the screening plate 5 is engaged with the slot at the upper end of the limiting plate 63.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
