Description

Technical Field

[0001] The utility model relates to the field of PVC reflective film production, in particular to a batching device for producing super-transparent and highly elastic PVC reflective film. Background Art

[0002] Ultra-transparent and highly elastic PVC reflective film is a special film material that combines high transparency, high elasticity and reflective function. This material is mainly used in occasions that require both visual clarity and safety warning functions, such as making reflective signs, advertising displays, transportation decorations, outdoor equipment, clothing accessories, etc. It can improve visibility and enhance safety performance by reflecting light sources at night or in low light conditions.

[0003] The most important step in the preparation of reflective film is the preparation of synthetic resin technology. The preparation of reflective film with synthetic resin technology requires a UV resin microprism layer and a PVC resin layer. The upper layer is a UV resin microprism layer, and the bottom layer is a PVC resin layer. During the preparation, acrylic acid, initiator, chain transfer agent and various additives and resins need to be added to the stirring equipment in a specific proportion. After sufficient mixing, the mixture is poured into a mold for molding, and then the desired film shape is formed by calendering or extrusion. However, at present, when adding various preparation compounds, some factories usually only use one mixing hopper for batching in order to increase the mixing speed. Different preparation compounds will produce a fusion reaction during the initial batching, and the synthetic resin material added by the former will easily have uneven mixing, resulting in differences in the quality of the synthetic resin in subsequent output.

[0004] Therefore, we propose a batching device for producing ultra-transparent and highly elastic PVC reflective film, which can prepare compounding agents by adding them in steps and improve the mixing speed. Utility Model Content

[0005] In order to overcome the disadvantage that different compound preparations will produce fusion reactions during the initial batching when only one mixing hopper is used for batching, and the synthetic resin materials added in the former will easily be mixed unevenly, the utility model provides a batching device for producing super-transparent and high-elastic PVC reflective film, which can add compound preparations in steps and increase the mixing speed.

[0006] The technical solution of the present utility model is as follows: A batching device for producing a super-transparent high-elastic PVC reflective film, comprising a base, a mixing mechanism, and a batching mechanism. A mixing mechanism for resin mixing is provided at the rear side of the top of the base. The mixing mechanism includes: a motor, a stirring tank, a coaxial double propeller, gears, a single-plate gear ring, a closed cover, a side cover, a handle, and a heating pipe. A stirring tank is connected to the right side of the top of the base. A closed cover is connected to the left side of the stirring tank. A motor is installed in the middle of the left side of the closed cover. The output shaft of the motor penetrates through the inner side of the closed cover and extends into the stirring tank. A coaxial double propeller is connected to the output shaft of the motor. A single-plate gear ring is rotatably connected to the rear side of the closed cover. Gears are rotatably connected to both sides on the left side of the single-plate gear ring. Both side gears are connected to the two shafts of the coaxial double propeller at the rear side, and the gears are meshed with the single-plate gear ring. A side cover is hinged to the right side of the stirring tank. A handle is connected to the middle rear side of the side cover. Heating pipes are arranged around the inside of the stirring tank. A batching mechanism for adding a compound agent to the resin is provided above the mixing mechanism. The batching mechanism includes: a material pump, a storage tank, and a top cover. A plurality of material pumps are arranged and installed on the top of the stirring tank, and each material pump is installed on the inner top of the stirring tank. The tops of the material pumps are all connected to storage tanks. The middle positions of the tops of the storage tanks are all hinged with top covers. A convex rod is provided on one side of the top of the top cover.

[0007] As an improvement of the above solution, the bottom position where the storage tank is connected to the material pump is in a quadrangular pyramid shape, and this quadrangular pyramid-shaped part makes the flow direction of the liquid-phase object in the storage tank concentrated.

[0008] As an improvement of the above solution, a purification mechanism is further included. A purification mechanism is provided at the front side of the top of the base. The purification mechanism includes: a pulley I, a synchronous belt, a pulley II, a fan I, an air inlet pipe, an absorption box, a feed pipe, a blocking block, an activated carbon plate, a fan II, a single propeller, and an exhaust pipe. A fan I is embedded and installed at one end near the motor on the upper side of the front part of the stirring tank. An air inlet pipe is connected to the front side of the fan I. The lower part of the front side of the air inlet pipe is connected to an absorption box. The left front side of the top of the absorption box is connected to a feed pipe, and a blocking block is plugged in the feed pipe. Activated carbon plates are connected to both the front and rear sides inside the absorption box. A fan II is embedded and installed on the upper left side of the absorption box. A pulley II is connected to the outer side of the middle part on the left side of the absorption box. A pulley I is connected to the output shaft of the motor. A synchronous belt is wound between the pulley I and the pulley II. A single stirring paddle is connected to the right side of the pulley II, and the single stirring paddle is located inside the absorption box. An exhaust pipe is connected to the middle and lower position on the left side outside the absorption box.

[0009] As an improvement of the above solution, the blocking block can be inserted and pulled out.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment: A batching device for producing a super-transparent high-elastic PVC reflective film, as Figures 1-9As shown in the figure, it includes a base 1, a mixing mechanism 2 and a batching mechanism 5. At the rear side of the top of the base 1, there is a mixing mechanism 2 for resin mixing. The mixing mechanism 2 includes: a motor 3, a mixing tank 21, a coaxial double propeller 22, gears 23, a single-plate gear ring 24, a closed cover 25, a side cover 26, a handle 27 and a heating pipe 28. On the right side of the top of the base 1, there is a fixedly connected mixing tank 21. On the left side of the mixing tank 21, there is a fixedly connected closed cover 25 to protect the gears 23 and the single-plate gear ring 24 from being affected by the batching. In the middle of the left side of the closed cover 25, there is a fixedly installed motor 3. The output shaft of the motor 3 penetrates through the inner side of the closed cover 25 and extends into the mixing tank 21. On the output shaft of the motor 3, there is a fixedly connected coaxial double propeller 22. At the rear side of the closed cover 25, there is a rotatably connected single-plate gear ring 24. On both sides of the left side of the single-plate gear ring 24, there are rotatably connected gears 23. Both sides of the gears 23 are connected to the two shafts of the coaxial double propeller 22 at the rear side, and the gears 23 are meshed with the single-plate gear ring 24, so that the coaxial double propeller 22 can rotate and achieve self-rotation at the same time, improving the mixing efficiency. On the right side of the mixing tank 21, there is a hinged side cover 26. At the rear side of the middle of the side cover 26, there is a fixedly connected handle 27, which is convenient for opening the side cover 26. Inside the mixing tank 21, there is a surrounding heating pipe 28 to heat the batching in the mixing tank 21 while mixing, improving the mixing efficiency. Above the mixing mechanism 2, there is a batching mechanism 5 for adding a composite agent to the resin. The batching mechanism 5 includes: a metering pump 51, a storage tank 52 and a top cover 53. On the top of the mixing tank 21, there are multiple metering pumps 51 arranged in a row, and each metering pump 51 is installed on the inner top of the mixing tank 21, so that the amount of batching can be controlled when it is fed. On the top of each metering pump 51, there is a fixedly connected storage tank 52. The bottom position where the storage tank 52 is connected to the metering pump 51 is in a quadrangular pyramid shape, and this quadrangular pyramid shape makes the flow direction of the liquid phase object in the tank concentrated. In the middle position of the top of each storage tank 52, there is a hinged top cover 53. On one side of the top of the top cover 53, there is a convex rod, which is convenient for the operator to open the top cover 53.

[0026] As Figure 8As shown in the figure, it further includes a purification mechanism 7. The purification mechanism 7 is provided at the front side of the top of the base 1. The purification mechanism 7 includes: pulley I 4, synchronous belt 41, pulley II 42, fan I 6, intake pipe 61, absorption tank 71, feed pipe 72, blocking block 73, activated carbon plate 74, fan II 75, single propeller 76 and exhaust pipe 77. A fan I 6 is embedded at one end of the upper side of the front part of the mixing tank 21 near the motor 3 to suck harmful gases into the absorption tank 71. The front side of the fan I 6 is welded with an intake pipe 61 for conveying harmful gases. The lower part of the front side of the intake pipe 61 is welded with an absorption tank 71. The left front side of the top of the absorption tank 71 is fixedly connected with a feed pipe 72. A blocking block 73 is plugged in the feed pipe 72, and the blocking block 73 can be inserted and pulled out. Activated carbon plates 74 are fixedly connected to both the front and rear sides inside the absorption tank 71 to absorb and purify the harmful gases in the absorption tank 71. A fan II 75 is embedded on the upper left side of the absorption tank 71. A pulley II 42 is welded at the left side position outside the middle part of the absorption tank 71. A pulley I 4 is fixedly connected to the output shaft of the motor 3. A synchronous belt 41 is wound between the pulley I 4 and the pulley II 42. The right side of the pulley II 42 is fixedly connected with a single agitator paddle, and the single agitator paddle is located inside the absorption tank 71 to simply mix the purification solution and the gas to improve the purification efficiency. An exhaust pipe 77 is fixedly connected to the lower middle position on the left side outside the absorption tank 71 for discharging the purified gas. A harmful gas detector is provided at the rear side of the exhaust pipe 77. When there is harmful gas in the exhaust pipe 77, the harmful gas detector will give an alarm to ensure that the incompletely purified harmful gas is not discharged.

[0027] As Figures 1-2 shown in the figure, it further includes a controller. The controller is fixedly installed on the right side of the front part of the base 1. The controller is electrically connected to the material pump 51, the heating pipe 28, the motor 3, the fan I 6, the fan II 75 and the exhaust pipe 77.

[0028] When an operator uses this device to stir and mix the reflective film ingredients, first, turn the top cover 53 upward to open the storage tank 52, then load the ingredient preparation agent and raw materials into the corresponding storage tank 52 as required respectively. After the ingredients are loaded, turn the top cover 53 downward to close the storage tank 52. Subsequently, turn on the feed pump 51 through the controller. The feed pump 51 pumps the ingredients in the storage tank 52 into the mixing tank 21. After the ingredients are prepared, turn on the motor 3, the first blower 6 and the heating pipe 28 through the controller. The output shaft of the motor 3 will drive the coupled double propellers 22 and the pulley I 4 to rotate. At the same time when the coupled double propellers 22 are rotating, the gear 23 rotates simultaneously. Under the cooperation of the gear 23 and the single-plate gear ring 24, the two sides of the coupled double propellers 22 will be driven to rotate self - sufficiently, further improving the mixing efficiency. The heating pipe 28 heats the ingredients at the same time. The coupled double propellers 22 mix the ingredients in the mixing tank 21 to make the ingredients fully mixed. Previously, in order to avoid excessive discharge of harmful gases generated during ingredient preparation in the high - temperature mixing tank 21, at this time, the blocking block 73 can be pulled out, and the purification solution is injected into the absorption tank 71 through the feed pipe 72. After completion, the blocking block 73 is plugged back. Subsequently, during the process of ingredient mixing, the generated harmful gases will be sucked into the intake pipe 61 by the first blower 6. The intake pipe 61 randomly transports the gas to the absorption tank 71. While the pulley I 4 is rotating, it will drive the pulley II 42 to rotate under the cooperation with the synchronous belt 41. The pulley II 42 will drive the single mixing paddle to rotate. When the harmful gases enter the absorption tank 71, the single mixing paddle will simply stir the gas and the purification solution in the absorption tank 71. The activated carbon plate 74 will adsorb the harmful gases. At the same time, start the second blower 75 through the controller to separate the solid particles in the harmful gases, further purifying the harmful gases. After the harmful gas treatment is completed, turn on the exhaust pipe 77 through the controller. The exhaust pipe 77 discharges the purified gas to the outside. If the harmful gas detector detects harmful gases in the exhaust pipe 77, an alarm will be issued. At this time, the operator needs to immediately close the exhaust pipe 77, and the gas will return to the absorption box for secondary purification. After completion, turn on the exhaust pipe 77 again to discharge the gas after secondary purification. After the mixing process is completed, turn off the first blower 6. At this time, the first blower 6 no longer sucks the harmful gases in the mixing tank 21. Then open the side cover 26 through the handle 27. The coupled double propellers 22 will convey the mixed reflective film ingredients from left to right. The operator can align the container with the discharge point to take the materials. After taking the materials, turn off the motor 3. At this time, the coupled double propellers 22 no longer rotate and wait for the next use. Repeat the above steps.

[0029] The above - mentioned embodiments are only the preferred embodiments of the present invention and are not used to limit the implementation scope of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
