DETAILED DESCRIPTION

[0036] The following will be described in detail below with reference to the accompanying drawings Figures 1-4 The application is further described in detail.

[0037] The application discloses a mothproof device suitable for a production workshop of a tobacco factory, which refers to Figure 1 , comprising a soundproof wall 1, the top of the soundproof wall 1 is provided with a ceiling 11, the bottom of the soundproof wall 1 is provided with a floor 12, the inner side of the soundproof wall 1 is provided with a diaphragm 2, the diaphragm 2 is made of flexible plastic cloth, the diaphragm 2 is parallel to and spaced apart from the inner side of the soundproof wall 1, and the distance between the diaphragm 2 and the soundproof wall 1 can be 3-5 cm. The upper side of the diaphragm 2 is connected to the lower surface of the ceiling 11, and the lower side of the diaphragm 2 is connected to the floor 12, so that the diaphragm 2 seals one side of the soundproof wall 1.

[0038] Reference Figure 1 On the ceiling 11, a plurality of support frames 31 are connected with an upper shaft 3, the upper shaft 3 is horizontally and parallel to the soundproof wall 1, and the upper shaft 3 is rotationally connected to the support frame 31. In the embodiment, the diaphragm 2 is continuously provided with a plurality of diaphragms 2 along the length direction of the soundproof wall 1, so that the two adjacent diaphragms 2 can be spliced with each other, thereby enabling the inner side of the soundproof wall 1 to be integrally closed by the diaphragm 2. The two upper shafts 3 at the ends of the two adjacent diaphragms 2 can abut against each other, so that the diaphragm 2 supported by the upper shaft 3 can be connected. The support frame 31 is arranged at the middle position of the upper shaft 3, two pull ropes 21 are connected to the diaphragm 2, the two pull ropes 21 are located on the two sides of the diaphragm 2, and the pull rope 21 is connected to the upper end of the diaphragm 2. The end of the pull rope 21 away from the diaphragm 2 is provided with a driving assembly 4, the driving assembly 4 is used for winding and unwinding the pull rope 21, so that the pull rope 21 pulls the upper end of the diaphragm 2 from the position of the floor 12 to the position of the ceiling 11, or releases the upper end of the diaphragm 2 from the position of the ceiling 11 to the position of the floor 12.

[0039] Reference Figure 1 and Figure 2The installation groove 13 is formed downwardly on the floor 12, the driving assembly 4 is arranged in the installation groove 13, and the winding shaft 5 is arranged in the installation groove 13 and connected to the lower side of the diaphragm 2, so that the winding shaft 5 winds the diaphragm 2. The transmission assembly 6 is arranged between the winding shaft 5 and the driving assembly 4 and is used to connect the driving assembly 4 and the winding shaft 5, so that the transmission assembly 6 drives the winding shaft 5 to rotate simultaneously when the driving assembly 4 works and completes the winding and unwinding of the diaphragm 2. Since the pull rope 21 and the diaphragm 2 operate simultaneously, the diaphragm 2 can be wound on the winding shaft 5 more neatly, the diaphragm 2 can be reused, and the damage of the diaphragm 2 is reduced. The cover plate 14 is arranged above the installation groove 13, and the pull rope 21 and the diaphragm 2 penetrate the cover plate 14.

[0040] Reference Figure 2 And Figure 3 The inside of the winding shaft 5 is arranged as a hollow structure, the fixed sleeve 51 is arranged at one end of the winding shaft 5, the fixed sleeve 51 can be fixed to the bottom of the installation groove 13, the inside of the fixed sleeve 51 is a hollow structure and communicates with the inside of the winding shaft 5, the adjacent two winding shafts 5 are connected through the fixed sleeve 51, and the pipeline 52 is connected to the side wall of the fixed sleeve 51. The pipeline 52 is connected to the smoke machine, the atomized medicament is sent into the inside of the pipeline 52 through the smoke machine, and then enters the inside of the winding shaft 5 through the fixed sleeve 51. The air holes 53 are arranged on the side wall of the winding shaft 5, the air holes 53 are arranged at intervals along the length direction of the winding shaft 5, and the air holes 53 communicate with the installation groove 13 when the diaphragm 2 is completely unwound from the winding shaft 5. The air inlet 15 is arranged on the inner side of the soundproof wall 1 and communicates with the interlayer structure in the inside of the soundproof wall 1, so that the atomized medicament in the inside of the winding shaft 5 flows out through the air holes 53 and then enters the inside of the soundproof wall 1 through the air inlet 15. When the diaphragm 2 is completely wound by the winding shaft 5, the atomized medicament flowing out of the air holes 53 can inhibit the hatching of eggs and hinder the metamorphosis of larvae on the surface of the diaphragm 2, so that the diaphragm 2 can be treated to prevent pests when the diaphragm 2 is in the installation groove 13, so as to prevent the workshop from being polluted by pests when the diaphragm 2 is unfolded.

[0041] Reference Figure 4The driving assembly 4 comprises a driving motor 41, a first worm 42 and a first worm wheel 43. The driving motor 41 is fixed on the side wall of the mounting groove 13. The output shaft of the driving motor 41 is coaxially fixedly connected with the first worm 42. The driving motor 41 can be a servo motor or a stepping motor. The first worm 42 is engaged with the first worm wheel 43. The first worm wheel 43 is rotatably installed in the mounting groove 13. A double-headed wheel 44 is connected to each end of the first worm wheel 43. The double-headed wheel 44 is used for winding the pull rope 21. The pull rope 21 is wound and unwound through the double-headed wheel 44. The diameter of the double-headed wheel 44 can be equal to the diameter of the winding shaft 5. Meanwhile, the transmission ratio of the double-headed wheel 44 and the winding shaft 5 through the transmission assembly 6 can be set to 1. In this way, the winding speed of the pull rope 21 by the double-headed wheel 44 is close to the unwinding speed of the diaphragm 2. Therefore, the movement of the diaphragm 2 is relatively stable.

[0042] With reference to Figure 4 A rotating shaft 45 is coaxially fixedly arranged at the center of the first worm wheel 43. The double-headed wheels 44 are sleeved on the rotating shaft 45. The axis of the double-headed wheel 44 is coaxial with the axis of the rotating shaft 45. The two double-headed wheels 44 are located at the two pull ropes 21 on both sides of the diaphragm 2. A spring 46 is arranged in the double-headed wheel 44. The spring 46 is sleeved on the rotating shaft 45. One end of the spring 46 is fixed on the double-headed wheel 44, and the other end is fixed on the rotating shaft 45. In this way, the spring 46 always has an elastic force. The elastic force of the spring 46 is used to drive the double-headed wheel 44 to rotate in the direction of winding the pull rope 21. The spring 46 always has an elastic force during the rotation of the first worm wheel 43. Therefore, the diaphragm 2 can be tensioned during the winding and unwinding of the diaphragm 2. Meanwhile, when there is a small difference between the rotating speeds of the double-headed wheel 44 and the winding shaft 5, the elastic force of the spring 46 can be adjusted to adapt to the difference, so as to prevent the pull rope 21 or the diaphragm 2 from being pulled off.

[0043] With reference to Figure 4A second worm wheel 71 is coaxially arranged on the winding shaft 5, a second worm 72 is engaged with the second worm wheel 71, the second worm 72 is connected with the transmission assembly 6, the first worm 42 and the second worm 72 are arranged in parallel and driven in the same direction, since the second worm wheel 71 is arranged at the end of the winding shaft 5, and the fixed sleeve 51 arranged at the end of the winding shaft 5 also occupies the length of the winding shaft 5, so as to enable the diaphragm 2 to be wound on the winding shaft 5, a guide groove 8 is arranged at the lower part of the diaphragm 2, the guide groove 8 gradually inclines to the center of the winding shaft 5 from top to bottom. Flexible magnetic strips 22 are fixedly arranged on the two vertical sides of the diaphragm 2, and the flexible magnetic strips 22 are slidingly connected in the guide grooves 8. The flexible magnetic strips 22 move along the guide grooves 8, the guide grooves 8 are fixed in the mounting grooves 13, the distance between the upper ends of the two guide grooves 8 is equal to the width of the diaphragm 2, and the distance between the lower ends of the two guide grooves 8 is less than the width of the diaphragm 2, so that the diaphragm 2 is contracted at the middle position, so that the diaphragm 2 has a gap after winding, which is convenient for entering the atomized medicament, and the pests on the surface of the diaphragm 2 are treated.

[0044] Reference Figure 4 The transmission assembly 6 includes a first bevel gear 61, a second bevel gear 62, a third bevel gear 63 and a fourth bevel gear 64, since the first worm 42 is located between the two I-shaped wheels 44, the first bevel gear 61 is coaxially connected with the first worm 42, the second bevel gear 62 and the third bevel gear 63 are coaxially arranged through a connecting shaft, and the connecting shaft is rotatably arranged in the mounting groove 13, the fourth bevel gear 64 is coaxially arranged with the second worm 72, the first bevel gear 61 is engaged with the second bevel gear 62, the third bevel gear 63 is engaged with the fourth bevel gear 64, and the first bevel gear 61, the second bevel gear 62, the third bevel gear 63 and the fourth bevel gear 64 have the same modulus and tooth number, so that the first worm 42 and the second worm 72 have the same rotation speed, so as to reduce the speed difference between the I-shaped wheel 44 and the winding shaft 5.

[0045] The working process of the embodiment is as follows:

[0046] First, the driving motor 41 drives the I-shaped wheel 44 to wind the pull rope 21, and the winding shaft 5 unwinds the diaphragm 2, so that the diaphragm 2 connected to one end of the pull rope 21 moves upward, when the diaphragm 2 reaches the position of the ceiling 11, the adjacent two diaphragms 2 can be connected and sealed by the flexible magnetic strip 22, and the atomized pesticide is sent into the soundproof wall 1 through the pipeline 52 and the hollow structure of the winding shaft 5, so as to control pests in the interior of the soundproof wall 1; when the diaphragm 2 is needed, the driving motor 41 is reversed to make the I-shaped wheel 44 unwind the pull rope 21, and the diaphragm 2 is wound on the winding shaft 5, when the diaphragm 2 is wound on the winding shaft 5, the diaphragm 2 is in the installation groove 13, after the atomized pesticide is sent into the hollow structure of the winding shaft 5 through the pipeline 52, the atomized pesticide will enter the gap of the diaphragm 2, so as to control pests on the diaphragm 2.
