Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant adding equipment, in particular to an adding equipment for automatically adding flame retardant. Background Art

[0002] Flame retardants are a class of chemicals used to slow, inhibit, or prevent the spread of flames. They are widely used in various applications to improve the flame-retardant properties of materials. Fire retardants are particularly commonly used to prevent the spread of fire or slow the burning rate of flames. Flame retardants require additive processing during the production process.

[0003] However, the existing flame retardant adding equipment requires manual addition of flame retardant materials during the processing, which is relatively labor-intensive. The automatic adding equipment only puts the pre-stored flame retardant materials into the processing at one time during the processing, which makes it difficult to perform flexible automatic addition according to the processing stage. Manual supervision and manual replenishment of materials are still required. In addition, the pre-stored materials are left for a long time before processing, which easily causes the materials to sink and accumulate, resulting in uneven materials and affecting the effect of the adding process.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an automatic adding device for adding flame retardants is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide an automatic adding device for adding flame retardant to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic adding device for adding flame retardant, comprising a storage barrel, the lower end of which is fixedly connected to a feeding box, the lower surface of which is fixedly provided with a feeding pipe, a driving motor is fixedly installed on the upper side of the outer surface of the storage barrel, the lower end of the driving motor is located inside the storage barrel and is provided with an adjusting mechanism, and a stirring rod is provided below the adjusting mechanism.

[0007] Preferably, the adjustment mechanism includes a reciprocating threaded barrel arranged above the lower end of the driving motor inside the storage barrel, a fixed plate is fixedly installed on the inner surface of the reciprocating threaded barrel, and a movable rod is slidably sleeved on the surface of the fixed plate inside the reciprocating threaded barrel.

[0008] Preferably, the adjustment mechanism further comprises an adjustment cylinder threadedly connected to the outer surface of the reciprocating threaded cylinder, a fixing cylinder is sleeved on the outer surface of the adjustment cylinder, and a bearing ring is provided at the lower end of the adjustment cylinder.

[0009] Preferably, the upper end of the stirring rod is fixedly connected to the bottom of the movable rod, and the adjusting cylinder and the fixed cylinder are limited by a slide groove and a slider, and the inner ring of the bearing ring is fixed to the stirring rod, and the outer ring is fixed to the adjusting cylinder.

[0010] Preferably, springs are fixedly mounted on both left and right sides of the lower inner surface of the feeding box, and a slot plate is fixedly mounted on the upper end of the spring.

[0011] Preferably, through cavities are opened on the left and right sides of the surface of the trough plate, and a connecting rod is fixedly installed on the middle upper surface of the trough plate.

[0012] Preferably, the upper end of the connecting rod is located inside the storage barrel, and a sealing plate is fixedly installed on the upper end of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a drive motor, an adjustment mechanism, a reciprocating threaded barrel, a fixed plate, a movable rod, an adjustment barrel, a fixed barrel, a bearing ring and a stirring rod. The drive motor can drive the reciprocating threaded barrel to rotate, and the adjustment barrel moves up and down under the limit of the fixed barrel, thereby pushing the entire stirring rod to move up and down through the bearing ring. The rotational force of the reciprocating threaded barrel is transmitted to the movable rod through the fixed plate, thereby rotating the stirring rod to stir the stored flame retardant to avoid accumulation. The up and down movement and stirring also make the flame retardant more evenly mixed.

[0015] 2. The utility model is provided with a spring, a groove plate, a through cavity, a connecting rod and a sealing plate. When adding materials, the stirring rod will continue to rotate, so that the flame retardant material will form a certain centrifugal force. The centrifugal force reduces the pressure of the sealing plate on the material. When the material inside the feeding box is reduced, the pressure of the groove plate becomes smaller, and the spring will push the groove plate up, thereby using the connecting rod to push the sealing plate up, opening the storage barrel, so that the flame retardant material falls and is automatically fed into the feeding box. The flame retardant material in the feeding box will pass through the through cavity and be discharged and fed by the feeding pipe, thereby realizing automatic feeding. If there is sufficient material inside the feeding box, the material pressure will press down the groove plate, so that the sealing plate will close the lower end opening of the storage barrel, and then no material will be fed. When there is no need to add material, the stirring rod stops rotating, and the material pressure in the storage barrel will compress the sealing plate to seal the storage barrel, which can also prevent the material from spilling and gushing out.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, an automatic adding device for adding flame retardants includes a storage barrel 1, the lower end of the storage barrel 1 is fixedly connected to a feeding box 5, the lower surface of the feeding box 5 is fixedly provided with a feeding pipe 6, and the upper side of the outer surface of the storage barrel 1 is fixedly installed with a driving motor 2. The lower end of the driving motor 2 is located inside the storage barrel 1 and is provided with an adjusting mechanism 3, and a stirring rod 4 is provided below the adjusting mechanism 3.

[0022] By adopting the above technical solution, a large amount of flame retardant can be pre-stored inside the storage barrel 1;

[0023] The feeding box 5 serves as a secondary transfer box during the flame retardant adding process and is used for storing the flame retardant when it is added.

[0024] Furthermore, the adjustment mechanism 3 includes a reciprocating threaded cylinder 301 disposed above the interior of the storage cylinder 1 at the lower end of the driving motor 2, a fixed plate 302 fixedly mounted on the inner surface of the reciprocating threaded cylinder 301, and a movable rod 303 slidably sleeved on the surface of the fixed plate 302 located inside the reciprocating threaded cylinder 301;

[0025] The adjusting mechanism 3 further includes an adjusting cylinder 304 threadedly connected to the outer surface of the reciprocating threaded cylinder 301, a fixed cylinder 305 is sleeved on the outer surface of the adjusting cylinder 304, a bearing ring 306 is provided at the lower end of the adjusting cylinder 304, and the upper end of the fixed cylinder 305 is fixedly connected to the inner surface of the storage cylinder 1;

[0026] The upper end of the stirring rod 4 is fixedly connected to the bottom of the movable rod 303, and the adjusting cylinder 304 and the fixed cylinder 305 are limited by a slide groove and a slider, and the inner ring of the bearing ring 306 is fixed to the stirring rod 4, and the outer ring is fixed to the adjusting cylinder 304.

[0027] By adopting the above technical solution, the driving motor 2 can drive the reciprocating threaded barrel 301 to rotate, and the adjusting barrel 304 can move up and down under the limit of the fixed barrel 305, thereby pushing the entire stirring rod 4 to move up and down through the bearing ring 306, and the rotational force of the reciprocating threaded barrel 301 will be transmitted to the movable rod 303 through the fixed plate 302, so that the stirring rod 4 rotates to stir the stored flame retardant to avoid accumulation, and the up and down movement and stirring also makes the flame retardant mixing more uniform and sufficient.

[0028] Furthermore, springs 7 are fixedly mounted on both left and right sides of the lower inner surface of the feeding box 5 , and a slot plate 8 is fixedly mounted on the upper end of the spring 7 .

[0029] By adopting the above technical solution, the spring 7 provides the slot plate 8 with a force to move upward.

[0030] Furthermore, through cavities 9 are opened on the left and right sides of the surface of the slot plate 8, a connecting rod 10 is fixedly installed on the middle upper surface of the slot plate 8, and the inner surface of the slot plate 8 is set to be an inclined surface.

[0031] By adopting the above technical solution, the material inside the feeding box 5 will be located on the slot plate 8. The material can be discharged from the slot plate 8 through the through cavity 9 and fall into the feeding pipe 6 for feeding.

[0032] Furthermore, the upper end of the connecting rod 10 is located inside the storage barrel 1 , and a sealing plate 11 is fixedly mounted on the upper end of the connecting rod 10 .

[0033] By adopting the above technical solution, when adding materials, the stirring rod 4 will continue to rotate, so that the flame retardant material generates a certain centrifugal force, and the centrifugal force reduces the pressure of the material on the sealing plate 11;

[0034] When the material inside the feeding box 5 decreases, the pressure on the slot plate 8 becomes smaller, and the spring 7 pushes the slot plate 8 upward, thereby using the connecting rod 10 to push the sealing plate 11 upward, opening the storage cylinder 1, and allowing the flame retardant material to fall and automatically be fed into the feeding box 5. The flame retardant material in the feeding box 5 will pass through the through cavity 9 and be discharged through the feeding pipe 6 to realize automatic feeding.

[0035] When there is sufficient material inside the feeding box 5, the material pressure will press down the groove plate 8, causing the sealing plate 11 to close the lower end opening of the storage barrel 1, and thus no material will be fed. When there is no need to add material, the stirring rod 4 stops rotating, and the material pressure in the storage barrel 1 will press the sealing plate 11 to seal the storage barrel 1, thereby preventing the material from spilling and gushing out.

[0036] Working principle: When using the automatic flame retardant adding device, first, manually add sufficient flame retardant material into the storage barrel 1. When it is not necessary to add material, the stirring rod 4 will not rotate and the material pressure in the storage barrel 1 will press the sealing plate 11 to block the storage barrel 1. When it is necessary to add material, the driving motor 2 can drive the reciprocating threaded barrel 301 to rotate, and the adjusting barrel 304 moves up and down under the limit of the fixed barrel 305, thereby pushing the entire stirring rod 4 to move up and down through the bearing ring 306, and the rotational force of the reciprocating threaded barrel 301 will be transmitted to the movable rod 303 through the fixed plate 302, so that the stirring rod 4 rotates to stir the stored flame retardant, and the stirring rod 4 will continue to rotate. This causes the flame retardant material to form a certain centrifugal force, and the centrifugal force reduces the material pressure on the sealing plate 11. When there is no material inside the feeding box 5 or the material is reduced to a certain amount, the pressure on the slot plate 8 becomes smaller, and the spring 7 will push the slot plate 8 upward, thereby using the connecting rod 10 to push the sealing plate 11 upward, opening the storage barrel 1, and allowing the flame retardant material to fall and automatically be fed into the feeding box 5, and replenished into the slot plate 8. The flame retardant material in the feeding box 5 will pass through the through cavity 9 and be discharged and fed using the feeding pipe 6, thereby realizing automatic feeding. If there is sufficient material inside the feeding box 5, the material pressure will press down the slot plate 8, causing the sealing plate 11 to close the lower end opening of the storage barrel 1, and then no material will be fed. This is the working principle of the automatic addition device for adding flame retardants.
