Description

Technical Field

[0001] This utility model belongs to the field of environmentally friendly flame-retardant polyvinyl alcohol film flame retardant addition technology, specifically an environmentally friendly flame-retardant polyvinyl alcohol film flame retardant addition device. Background Technology

[0002] Polyvinyl alcohol (PVA) is an organic compound with the chemical formula [C₂H₄O]n. It appears as a white, flaky, flocculent, or powdery solid, and is odorless. It is soluble in water (above 95°C), slightly soluble in dimethyl sulfoxide, and insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. PVA is an important chemical raw material used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon, fabric treatment agents, emulsifiers, paper coatings, adhesives, and glues.

[0003] Flame retardants for polyethylene are classified into two types: reactive and additive. Reactive flame retardants are mainly synthesized by synthesizing polymers with flame-retardant elements, so that the polymer main chain or side chain contains flame-retardant elements, thus achieving a flame-retardant effect. Additive flame retardants refer to flame retardants that are blended with polymer materials in a physically dispersed state to exert a flame-retardant effect.

[0004] When processing flame retardants for additive-type polyethylene, an additive device is needed to add various materials to improve the performance of the flame retardant and facilitate subsequent processing. However, existing additive devices cannot quantitatively process the added materials, which can easily cause blockages in the feed pipe when excessive materials are added, thus affecting the effectiveness of the additive process.

[0005] Therefore, an environmentally friendly flame-retardant polyvinyl alcohol film flame retardant addition device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an environmentally friendly flame-retardant polyvinyl alcohol film flame retardant addition device, which has the advantage of being able to quantitatively process the amount of material fed, thus avoiding blockage of the feeding pipe caused by a large amount of material during the feeding process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly flame-retardant polyvinyl alcohol film flame retardant addition device, comprising an addition box, a lower funnel connected to the upper surface of the addition box, a flow pipe installed on the lower surface of the addition box, a support frame connected to the surface of the flow pipe, and a metering component installed on the surface of the addition box;

[0008] The quantitative component includes a feeding pipe, which is installed inside the adding box. A baffle plate is provided at the outlet of the feeding pipe. An L-shaped plate is slidably connected in a through groove on the surface of the adding box. One end of the L-shaped plate is connected to the baffle plate. A support plate is installed on one side surface of the adding box. A movable rod is rotatably connected between two support plates. A pusher plate is installed on the surface of the movable rod. The movable rod is located on one side surface of the pusher plate. The pusher plate is in contact with the L-shaped plate. The feeding component is installed on the surface of the flow pipe.

[0009] Preferably, a drive motor is mounted on one side surface of one of the support plates, and the output end of the drive motor passes through the support plate and is connected to one end of the movable rod.

[0010] Preferably, an adjustment plate is installed on the bottom surface of the L-shaped plate, and a guide rod is slidably connected in a through hole on the surface of the adjustment plate. One end of the guide rod passes through the adjustment plate and is connected to the adding box.

[0011] Preferably, a return spring is sleeved on the surface of the guide rod, one end of the return spring is connected to the adjusting plate, and the other end of the return spring is connected to the adding box.

[0012] Preferably, one end of the feed pipe is connected to the lower funnel.

[0013] Preferably, the feeding assembly includes a tapered tube, the surface of the flow tube is fitted with a tapered tube, the center point of the feeding tube and the tapered tube are aligned, a connecting plate is slidably connected inside the tapered tube, a tapered guide block is fitted on the surface of the connecting plate, a sliding plate is fitted on the surface of the connecting plate, a groove adapted to the sliding plate is opened on the surface of the flow tube, one end of the sliding plate passes through the feeding tube and extends to the outside of the feeding tube, a limiting rod is slidably connected in a through hole opened on the surface of the sliding plate, both ends of the limiting rod pass through the sliding plate and are respectively connected to the adding box and the support frame.

[0014] Preferably, a second return spring is sleeved on the surface of the limiting rod, one end of the second return spring is connected to the lower slide plate, and the other end of the second return spring is connected to the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model incorporates a quantitative component. When adding materials for processing polyvinyl alcohol flame retardant, the material is first poured into the lower funnel. The lower funnel then discharges the material into the feeding pipe inside the addition box. At this point, the operator starts the drive motor. The output of the drive motor drives the movable rod between the support plates to rotate. During the rotation of the movable rod, the push plate rotates. Since the movable rod is not at the center point of the push plate, the rotation of the push plate pushes the L-shaped plate to move. During the movement of the L-shaped plate, the baffle plate reciprocates, blocking the feeding pipe and thus discharging the material intermittently. The discharged material flows through the feeding pipe into the flow pipe for subsequent processing, thereby avoiding blockage of the feeding pipe by a large amount of material.

[0017] 2. This utility model incorporates a feeding assembly. When material flows into the flow pipe on the support frame, it falls into the conical tube. At this point, the conical guide block on the connecting plate blocks the conical tube. When the material accumulates to a suitable amount, the connecting plate moves the lower slide plate downwards. The lower slide plate slides within the groove on the surface of the flow pipe and against the surface of the limiting rod. The limiting rod guides the movement of the lower slide plate, preventing it from shifting position. Then, the connecting plate disengages the conical guide block from the conical tube, allowing the material to fall out. During the falling process, the conical guide block disperses the material, preventing accumulation. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a drying device for metal film, including an adding box 1, a lower funnel 12 connected to the upper surface of the adding box 1, a flow tube 13 installed on the lower surface of the adding box 1, a support frame 14 connected to the surface of the flow tube 13, and a metering component 2 installed on the surface of the adding box 1.

[0025] The quantitative component 2 includes a feeding pipe 21. The feeding pipe 21 is installed inside the adding box 1. A baffle plate 22 is provided at the outlet of the feeding pipe 21. An L-shaped plate 23 is slidably connected in a through groove on the surface of the adding box 1. One end of the L-shaped plate 23 is connected to the baffle plate 22. A support plate 24 is installed on one side surface of the adding box 1. A movable rod 25 is rotatably connected between the two support plates 24. A push plate 26 is installed on the surface of the movable rod 25. The movable rod 25 is located on one side surface of the push plate 26. The push plate 26 is in contact with the L-shaped plate 23. The feeding component 3 is installed on the surface of the flow pipe 13.

[0026] Specifically, such as Figure 1 As shown, a drive motor 27 is installed on one side surface of one of the support plates 24. The output end of the drive motor 27 passes through the support plate 24 and is connected to one end of the movable rod 25. An adjustment plate 28 is installed on the bottom surface of the L-shaped plate 23. A guide rod 29 is slidably connected in the through hole opened on the surface of the adjustment plate 28. One end of the guide rod 29 passes through the adjustment plate 28 and is connected to the addition box 1. A return spring 210 is sleeved on the surface of the guide rod 29. One end of the return spring 210 is connected to the adjustment plate 28, and the other end of the return spring 210 is connected to the addition box 1. One end of the discharge pipe 21 is connected to the lower funnel 12.

[0027] In this implementation plan: when adding materials for processing polyvinyl alcohol flame retardant, the material is first poured into the lower funnel 12. The lower funnel 12 then discharges the material into the discharge pipe 21 inside the addition box 1. At this time, the operator starts the drive motor 27. The output end of the drive motor 27 drives the movable rod 25 between the support plates 24 to rotate. During the rotation of the movable rod 25, the push plate 26 is rotated. Since the movable rod 25 is not at the center point of the push plate 26, the push plate 26 rotates and pushes the L-shaped plate 23 to move. During the movement of the L-shaped plate 23, the baffle plate 22 reciprocates, which can block the discharge pipe 21, thereby intermittently discharging the material from the discharge pipe 21. After discharge, the material enters the flow pipe 13 along the discharge pipe 21 for subsequent processing, thereby avoiding the blockage of the discharge pipe 21 by a large amount of material.

[0028] When the L-shaped plate 23 moves, it causes the adjusting plate 28 to slide on the surface of the guide rod 29. The guide rod 29 can guide the movement of the L-shaped plate 23, preventing the L-shaped plate 23 from shifting position during movement and further improving the stability of the L-shaped plate 23 during movement. When the L-shaped plate 23 compresses the return spring 210 during movement, the return spring 210 is deformed by compression and can assist the L-shaped plate 23 in resetting, thereby further improving the effect of the device during use.

[0029] Please refer to Example 2 Figure 1 , Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 is that: the feeding assembly 3 includes a tapered tube 31, the surface of the flow tube 13 is fitted with the tapered tube 31, the center point of the feeding tube 21 is aligned with the center point of the tapered tube 31, the inside of the tapered tube 31 is slidably connected with a connecting plate 32, the surface of the connecting plate 32 is fitted with a tapered guide block 33, the surface of the connecting plate 32 is fitted with a sliding plate 34, the surface of the flow tube 13 is provided with a groove that matches the sliding plate 34, one end of the sliding plate 34 passes through the feeding tube 21 and extends to the outside of the feeding tube 21, a limiting rod 35 is slidably connected in the through hole opened on the surface of the sliding plate 34, both ends of the limiting rod 35 pass through the sliding plate 34 and are respectively connected to the adding box 1 and the support frame 14.

[0030] Specifically, such as Figure 1-4 As shown, a second reset spring 36 is sleeved on the surface of the limiting rod 35. One end of the second reset spring 36 is connected to the lower slide plate 34, and the other end of the second reset spring 36 is connected to the support frame 14.

[0031] In this implementation scheme: when the material flows into the flow pipe 13 on the support frame 14, the material falls into the conical pipe 31. At this time, the conical guide block 33 on the connecting plate 32 blocks the conical pipe 31. When the material accumulates to a suitable amount, the connecting plate 32 drives the lower slide plate 34 to move downward. The lower slide plate 34 slides in the groove opened on the surface of the flow pipe 13 and slides on the surface of the limiting rod 35. The limiting rod 35 can guide the movement of the lower slide plate 34 to prevent the lower slide plate 34 from deviating during movement. At this time, the connecting plate 32 drives the conical guide block 33 to disengage from the conical pipe 31, so that the material falls from the conical pipe 31. During the falling process, the conical guide block 33 can disperse the material, thereby preventing the material from accumulating.

[0032] When the sliding plate 34 slides on the surface of the limiting rod 35, the sliding plate 34 presses the second return spring 36. At this time, the second return spring 36 deforms. The second return spring 36 can quantitatively process the material on the connecting plate 32 and the conical guide block 33. When the weight of the material on the connecting plate 32 and the conical guide block 33 is less than the weight of the second return spring 36, the elastic force of the second return spring 36 can stabilize the position of the connecting plate 32 and the conical guide block 33. When the weight of the material on the connecting plate 32 and the conical guide block 33 is greater than the weight of the second return spring 36, the connecting plate 32 and the conical guide block 33 slide down and press the second return spring 36. After the material on the connecting plate 32 and the conical guide block 33 has been discharged, the second return spring 36 drives the connecting plate 32 and the conical guide block 33 to re-seal the conical tube 31, thus facilitating the operation of the operator.
