Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, and in particular to a water-based resin dripping device. Background Technology

[0002] With increasingly stringent environmental protection requirements and the continuous expansion of the application of water-based resins in many fields such as coatings, adhesives, and inks, the market demand for them is showing a rapid growth trend.

[0003] Traditional dripping devices often use simple valves to control the dripping flow rate. This method makes it difficult to achieve precise control of the amount of resin liquid added. Since water-based resin liquids contain solid particles, impurities, or incompletely dissolved components, these substances can easily clog the dripper during the dripping process, leading to dripping interruption or unstable flow rate. At the same time, even small changes in valve opening can cause large fluctuations in flow rate, resulting in significant errors in the amount of resin liquid added each time, which makes it impossible to guarantee the stability and consistency of product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-based resin dripping device, comprising a support frame, a resin cylinder fixedly installed at the top of the support frame, and a dripping mechanism provided at the bottom of the support frame. The dripping mechanism includes a fixed rod installed at the bottom of the support frame, a plurality of drip heads installed on the surface of the fixed rod, and a valve provided on the outer surface of the drip heads. A ball cylinder is connected to the top of the drip heads, and a collection pipe is connected to the bottom of the resin cylinder. The top of the ball cylinder and the collection pipe are connected and installed through a discharge pipe. An inner cylinder for quantitatively discharging resin liquid is rotatably installed inside the ball cylinder. A first motor is fixedly installed on the outer surface of the support frame, and the first motor is fixedly connected to the inner cylinder through a rotating rod.

[0006] As a preferred embodiment of this utility model, a plurality of sealing rings are installed between the ball cylinder and the inner cylinder, and the outer surface of the sealing rings is covered with an oil film for reducing friction.

[0007] As a preferred embodiment of this utility model, the inner cylinder is provided with a filtration mechanism, which includes two protective nets installed inside the inner cylinder. The surface of the protective nets is coated with a smooth coating to reduce resin liquid blockage.

[0008] As a preferred embodiment of this utility model, a folding soft plate is rotatably installed inside the discharge pipe, and the surface of the protective net is connected by an elastic rope to a striking block for continuously striking the folding soft plate.

[0009] As a preferred technical solution of this utility model, the inner cylinder is provided with an adsorption assembly. The adsorption assembly includes an adsorption block fixedly installed at one end of the rotating rod inside the inner cylinder.

[0010] As a preferred technical solution of this utility model, the dripper head is provided with a discharge mechanism inside. The discharge mechanism includes a spiral impeller rotatably installed inside the dripper head.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a first motor to drive the inner cylinder to rotate, and utilizes the through hole on the surface of the inner cylinder connected to the collecting pipe to achieve quantitative discharge of resin liquid. The rotation angle and speed of the inner cylinder can be precisely controlled, so that the amount of resin liquid entering the ball cylinder and finally dripping from the dripper can remain highly consistent each time. This quantitative control method is not affected by external factors such as resin liquid viscosity and pressure, effectively avoiding product quality fluctuations caused by inaccurate dripping, ensuring the stability and consistency of product performance in each batch, improving the product qualification rate, reducing the defect rate, and saving production costs for enterprises.

[0014] 2. This utility model uses a protective net connected by an elastic rope to continuously strike the folded soft plate, causing the folded soft plate to vibrate. This further prevents the resin liquid from adhering to and clogging the inner wall of the discharge pipe, ensuring the smooth flow of the resin liquid. At the same time, the adsorption component inside the inner cylinder can adsorb tiny impurities and odor substances in the resin liquid through the pores on the surface of the adsorption block and the carbon block inside, reducing the impact of these factors on the dripping process.

[0015] 3. This utility model uses an exhaust mechanism set on the outer surface of the support frame to extract air from the discharge pipe through the air collection pipe via an air pump, effectively eliminating air bubbles in the resin liquid. This prevents air bubbles from entering the dripper during the dripping process, thus avoiding affecting the accuracy and uniformity of the dripping and ensuring the continuous and stable dripping of the resin liquid.

[0022] 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.

[0023] Please see Figure 1-5This utility model provides an aqueous resin dripping device, including a support frame 1, a resin cylinder 2 fixedly installed at the top of the support frame 1, and a dripping mechanism 3 provided at the bottom of the support frame 1. The dripping mechanism 3 includes a fixed rod 38 installed at the bottom of the support frame 1, a plurality of drip heads 310 installed on the surface of the fixed rod 38, and a valve 39 provided on the outer surface of the drip heads 310. A ball cylinder 33 is connected to the top of the drip heads 310, and a collection pipe 31 is connected to the bottom of the resin cylinder 2. The top of the ball cylinder 33 and the collection pipe 31 are connected and installed through a discharge pipe 32. An inner cylinder 36 for quantitatively discharging resin liquid is rotatably installed inside the ball cylinder 33. A first motor 35 is fixedly installed on the outer surface of the support frame 1. The first motor 35 is fixedly connected to the inner cylinder 36 through a rotating rod 34. A through hole communicating with the collection pipe 31 is opened on the surface of the inner cylinder 36.

[0024] The inner cylinder 36 is rotatably installed inside the ball cylinder 33. The surface of the inner cylinder 36 has a through hole that communicates with the collecting pipe 31. The first motor 35 drives the inner cylinder 36 to rotate through the rotating rod 34. When the through hole rotates to the appropriate position, the resin can enter the ball cylinder 33 through the through hole and finally drip out from the dripper 310 on the fixed rod 38, realizing the resin dripping operation. Moreover, the rotation angle and speed of the inner cylinder 36 can be precisely controlled, so that the amount of resin liquid entering the ball cylinder 33 and finally dripping out from the dripper 310 each time can maintain a high degree of consistency. This quantitative control method is not affected by external factors such as resin liquid viscosity and pressure, effectively avoiding product quality fluctuations caused by inaccurate dripping amount, ensuring the stability and consistency of the performance of each batch of products, and improving the product qualification rate.

[0025] In some embodiments, a plurality of sealing rings 37 are installed between the ball cylinder 33 and the inner cylinder 36, and the outer surface of the sealing rings 37 is covered with an oil film for reducing friction.

[0026] When the inner cylinder 36 rotates inside the ball cylinder 33, the sealing ring 37 acts as a seal to prevent resin liquid from leaking from the gap between the ball cylinder 33 and the inner cylinder 36, thus avoiding waste of resin liquid and ensuring the cleanliness of the environment around the dripping device, reducing potential safety hazards caused by resin liquid leakage. The oil film reduces the friction between the sealing ring 37 and the ball cylinder 33 and the inner cylinder 36, reducing the resistance to the rotation of the inner cylinder 36, making it easier for the first motor 35 to drive the inner cylinder 36 to rotate, reducing energy loss, and improving the operational stability and service life of the device.

[0027] In some embodiments, a filter mechanism 4 is provided inside the inner cylinder 36. The filter mechanism 4 includes two protective nets 41 installed inside the inner cylinder 36. The surface of the protective nets 41 is coated with a smooth coating to reduce resin liquid blockage.

[0028] When the resin liquid flows through the inner cylinder 36, the protective net 41 can intercept solid particles and impurities in the resin liquid, preventing them from entering the subsequent dripping channel and causing blockage; the smooth coating reduces the adhesion of the resin liquid to the surface of the protective net 41, allowing the resin liquid to pass through the protective net 41 more smoothly, reducing the occurrence of blockage of the protective net 41, ensuring the smooth passage of the resin liquid, and improving the continuity of the dripping process.

[0029] In some embodiments, a folding flexible plate 44 is rotatably mounted inside the discharge pipe 32, and a striking block 42 for continuously striking the folding flexible plate 44 is connected to the surface of the protective net 41 by an elastic rope.

[0030] During the rotation of the inner cylinder 36, the protective net 41 also moves, causing the striking block 42 to continuously strike the folded flexible plate 44, resulting in vibration of the folded flexible plate 44. This vibration prevents the resin liquid from adhering to and accumulating on the inner wall of the discharge pipe 32, ensuring the unobstructed flow of the discharge pipe 32 and allowing the resin liquid to flow smoothly from the resin cylinder 2 to the dripper 310. It also helps to break up air bubbles in the resin liquid, making the resin liquid more uniform and improving the accuracy and stability of the dripping.

[0031] In some embodiments, an adsorption assembly 43 is provided inside the inner cylinder 36. The adsorption assembly 43 includes an adsorption block 431 fixedly installed at one end of the rotating rod 34 inside the inner cylinder 36. The surface of the adsorption block 431 is provided with a plurality of air holes 432. A reinforcing plate 435 is fixedly installed inside the adsorption block 431, and carbon blocks 434 are provided in the gaps between the reinforcing plate 435. A membrane 433 for air permeability and protection is installed on the surface of the reinforcing plate 435 near the adsorption block 431.

[0032] When the resin liquid flows through the inner cylinder 36, the adsorption block 431 adsorbs the tiny impurities and odor substances in the resin liquid through the pores 432, the carbon block 434 plays the role of adsorption and purification, and the breathable protective film 433 prevents the resin liquid from directly entering the interior of the adsorption block 431 and damaging the carbon block 434.

[0033] In some embodiments, the dripper 310 is provided with a discharge mechanism 5 inside. The discharge mechanism 5 includes a spiral impeller 54 rotatably installed inside the dripper 310. A third gear 55 is rotatably installed on the inner wall of the dripper 310 and is fixedly connected to the spiral impeller 54. A second gear 53 is rotatably installed inside the dripper 310. A second motor 51 is fixedly installed on the outer surface of the dripper 310. A first gear 52 is fixedly installed on the output shaft of the second motor 51. The second gear 53 meshes with the first gear 52 and the third gear 55.

[0034] The second motor 51 drives the first gear 52 to rotate. The first gear 52 meshes with the second gear 53 and the third gear 55 to drive the third gear 55 to rotate. The third gear 55 is fixedly connected to the spiral impeller 54, so that the spiral impeller 54 rotates inside the dripper 310. This allows the residual resin liquid inside the dripper 310 to be discharged in a timely and thorough manner, effectively preventing the resin liquid from solidifying and clogging the dripper 310. This ensures that the dripper 310 is always in a smooth state, improving the reliability and service life of the dripping device.

[0035] In some embodiments, an exhaust mechanism 6 is provided on the outer surface of the support frame 1. The exhaust mechanism 6 includes an air pump 61 installed at the top of the support frame 1. An air collecting pipe 62 is fixedly installed on the outer surface of the support frame 1. The input end of the air pump 61 is connected to the air collecting pipe 62. The air collecting pipe 62 and the discharge pipe 32 are connected and installed through a connecting pipe 63. A pressure reducing valve 64 is provided on the connecting pipe 63.

[0036] When the air pump 61 is working, it extracts the air from the discharge pipe 32 through the air collection pipe 62 and the connecting pipe 63, avoiding problems such as inaccurate dripping amount and uneven dripping caused by the presence of air bubbles, thus improving the quality and accuracy of dripping. The pressure reducing valve 64 can adjust the exhaust pressure, making the exhaust process stable and controllable, thereby eliminating air bubbles in the resin liquid and ensuring that the dripped resin liquid is free of air bubbles, so that the dripping device can adapt to the exhaust requirements of resin liquids with different viscosities and properties.

[0037] Working principle: When using the resin cylinder 2 with the dripper 310 for dripping, the first motor 35 is started, which drives the inner cylinder 36 to rotate via the rotating rod 34. When the through hole rotates to the appropriate position, the resin can enter the ball cylinder 33 through the through hole and finally drip out from the dripper 310 on the fixed rod 38, realizing the resin dripping operation. Moreover, the rotation angle and speed of the inner cylinder 36 can be precisely controlled, so that the amount of resin liquid entering the ball cylinder 33 and finally dripping out from the dripper 310 each time can maintain a high degree of consistency. This quantitative control method is not affected by external factors such as resin viscosity and pressure, effectively avoiding product quality fluctuations caused by inaccurate dripping, ensuring the stability and consistency of the performance of each batch of products, and improving the product qualification rate.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
