[0002] Emulsification plays a vital role in the processing of plastic bottle caps. When processing plastic bottle caps, the raw materials need to be emulsified because emulsifiers can effectively reduce the surface tension of plastic melts, improve their fluidity and processing properties, make plastics flow more smoothly during melting and injection molding, and reduce resistance and energy consumption in production. In addition, it can make the molecules of plastic raw materials more evenly mixed, reduce component deviations in products, and improve product quality and quality stability.

[0003] At present, when the raw materials of plastic bottle caps are emulsified and polymerized, they are processed in a stirring kettle. Since the amount of raw materials emulsified at a time is relatively large, a stirring kettle with a larger volume is usually used to meet the stirring requirements. Although the stirring kettle with a large volume can accommodate a large amount of plastic raw materials for emulsification at a time, the depth of the kettle body will also be large. In the process of emulsification and stirring, the stirring conditions are different for raw materials at different levels, and the emulsification conditions are also different.

[0036] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] Embodiment, this embodiment provides a constant temperature emulsification device for raw materials used in processing plastic bottle caps, such as Figure 1As shown, the emulsifying cylinder 2 includes a feed pipe 21 at the upper end, and the raw materials and emulsifier of the plastic bottle caps are fed from the feed pipe 21. Both ends of the emulsifying cylinder 2 are closed structures to prevent the raw material box emulsifier from overflowing. A mixing hollow tube 3 is provided in the emulsifying cylinder 2, which is rotatably connected to the side walls of the two closed structures. A turning plate 31 is provided on the radial side wall of the mixing hollow tube 3. Here, the end of the turning plate 31 contacts the inner wall of the emulsifying cylinder 2 to ensure that the turning plate 31 can pick up the raw materials close to the inner wall of the emulsifying cylinder 2 when rotating. The radial side wall of the mixing hollow tube 3 is also provided with a plurality of dividing plates 32 arranged opposite to the turning plate 31. A scooping space for scooping raw materials is formed between the turning plate 31 and the plurality of dividing plates 32. The turning plate 31 serves as a supporting plate for scooping raw materials and emulsifiers. The purpose of designing the dividing plates 32 here is to prevent the scooped raw materials and emulsifiers from flowing quickly along the wall of the turning plate 31, but to flow out through the gap between two adjacent dividing plates 32. In this way, the scooped raw materials and emulsifiers can be fully integrated in a small amount and in a small space in the scooping space.

[0038] like Figure 8 and Fig. 9 As shown, a shearing roller 36 is first axially rotated and inserted in the mixing hollow tube 3, and a support frame is rotatably connected to one end of the shearing roller 36. The end of the support frame is fixedly connected to the inner wall of one end of the mixing hollow tube 3. The other end of the shearing roller 36 rotates to pass through the other end of the mixing hollow tube 3 and is fixed with a flange 313. The closed structure at the other end of the emulsifying cylinder 2 is connected to a power device, and the power device has a motor 1. The output end of the motor 1 rotates through one of the closed structure side walls of the emulsifying cylinder 2 and is fixedly connected to the flange 313. The output end of the motor 1 is connected to the shearing roller 36 through the flange 313 to achieve power connection.

[0039] The turning plate 31 needs a power source to rotate. Specifically, one end of the shearing roller 36 located in the mixing hollow tube 3 is fixedly sleeved with a toothed disc 312. The inner wall of the mixing hollow tube 3 is fixed with a toothed plate 311 that is engaged between two adjacent teeth on the toothed disc 312. The output end of the motor 1 drives the shearing roller 36 along the mixing hollow tube 3. Fig. 9 The toothed disc 312 can drive the toothed plate 311 to rotate around the toothed disc 312 in a circle, that is, along the Q direction shown in FIG. Fig. 9 If the mixing hollow tube 3 rotates in the direction shown by Q1, the mixing hollow tube 3 can rotate synchronously, thereby driving the turning plate 31 to turn synchronously to pick up and stir the raw materials.

[0040] When the mixing hollow tube 3 rotates in the emulsifying barrel 2, it can drive the turning plate 31 to make a circular motion with the mixing hollow tube 3 as the rotation center. At the same time, the turning plate 31 can scoop up the raw materials in the emulsifying barrel 2, and the scooped raw materials are diverted from the gap between two adjacent dividing plates 32 and then flow back into the emulsifying barrel 2. In this process, raw materials at different depths in the emulsifying barrel 2 can be scooped up together. In the process of diverting from the gap between two adjacent dividing plates 32 and then flowing back into the emulsifying barrel 2, the position of the raw materials can be changed, the raw materials can be directly and quickly contacted with the emulsifier, and the emulsification efficiency can be accelerated.

[0041] At the same time, a shearing blade 37 is provided on the radial side wall of the shearing roller 36. The shearing blade 37 rotates to form a rotating vortex in the mixing hollow tube 3 in the same direction as the rotation direction of the shearing blade 37. At the same time, a feed port 35 and a plurality of discharge holes 34 are provided on the radial side wall of the mixing hollow tube 3 in the scooping space. The diameter of the feed port 35 is larger than the diameter of each discharge hole 34. When the raw material scooped by the turning plate 31 continues to turn and tilt as the turning plate 31 turns, the raw material can be scooped along the Figure 4 The liquid flows into the feed port 35 in the direction A2 shown in the figure, and then flows into the mixing hollow tube 3, and is sheared and shredded by a plurality of shear blades 37, as shown in the figure. Figure 4 As shown, the shredded raw materials are followed by Figure 4 The rotating vortex flows in the direction A shown in the figure, and in this process, the plurality of discharge holes 34 are discharged as shown in the figure. Figure 4 The liquid flows back to the emulsifying cylinder 2 in the direction of A3, and the large particles continue to be peeled in the mixing hollow tube 3.

[0042] In summary, the mixing hollow tube 3 is rotated to drive the turning plate 31 to pick up the plastic raw materials and emulsifiers in the emulsifying cylinder 2, and the picked raw materials are separated from the gap between the two adjacent dividing plates 32 and flow back into the emulsifying cylinder 2, so that the raw materials at different levels are turned over. It should be noted that a gap is left between the end of the dividing plate 33 and the inner wall of the emulsifying cylinder 2. Figure 4 There is a gap between the end of the dividing plate 32 and the inner wall of the emulsifying tube 2, such as Figure 4 L1, the partition plate 33 and the material dividing plate 32 do not affect the material turning plate 31 to pick up the raw materials. At the same time, as the material turning plate 31 flips to an inclined state, the raw materials quickly enter the mixing hollow tube 3 from the larger opening of the feed port 35 along the material turning plate 31, and the rotating shear blade 37 is peeled in the mixing hollow tube 3. The small particles of plastic after peeling can be more fully contacted and fused with the emulsifier. The shear blade 37 rotates in the mixing hollow tube 3 to form a rotating vortex in the same direction as the rotation of the shear blade 37, which can drive the peeled raw materials to flow back from multiple discharge holes 34 to the emulsifying barrel 2, and realize multiple batches of small-scale cyclic peeling operations in the mixing hollow tube 3, and finally ensure that the plastic principle is fully contacted with the emulsifier for emulsification operation, thereby improving the emulsification efficiency.

[0043] It should be noted that, in further Figure 5 and Figure 6 As shown, a triangular hollow guide seat 38 located at the feed port 35 is fixed to the inner wall of the mixing hollow tube 3. A plurality of guide holes 39 are opened on the side wall of the hollow guide seat 38 facing away from the discharge hole 34. The opening direction of the guide holes 39 faces away from the discharge hole 34 and faces the rotation direction of the rotary cutting vortex. In this way, the raw materials can enter from the feed port 35 as much as possible, and the raw materials after rotary cutting overflow from the discharge hole 34, forming a circulating emulsification path. Figure 3 and Figure 4 As shown, the radial side wall of the mixing hollow tube 3 is still fixed with a partition plate 33 located between the feed port 35 and the discharge hole 34. The partition plate 33 divides the scooping space into two. The purpose of the diameter of the feed port 35 being larger than the diameter of each discharge hole 34 is that, and a partition plate 33 is provided between the feed port 35 and the discharge hole 34. The function of the partition plate 33 is to prevent the raw material just discharged from the discharge hole 34 from being sucked into the feed port 35 by the negative pressure vortex and being peeled again.

[0044] During the emulsification process, it is necessary to carry out the emulsification at a constant temperature of 60-80° to ensure efficient emulsification. At the same time, the feed pipe 21 is sealed with a cover to achieve a closed constant temperature condition. Figure 2 As shown, an external sleeve 22 is connected to the closed structure at one end, the mixing hollow tube 3 is in communication with the external sleeve 22, a hot air pipe 24 is embedded in the end of the external sleeve 22, and a hot air blower is connected to the end of the hot air pipe 24 outside the external sleeve 22. The hot air blower supplies hot air to the external sleeve 22 through the hot air pipe 24, and the hot air is stable within the range of 60-80°, and finally enters the mixing hollow tube 3, and enters the emulsifying cylinder 2 from the feed port 35 or the discharge hole 34 in the mixing hollow tube 3, so as to ensure that the entire emulsifying space is in a constant temperature state.

[0045] At the same time, when the emulsification is completed, the raw materials need to be extracted from the emulsification cylinder 2, such as Figure 2 As shown, a drawing pipe 23 is also embedded in the end of the external sleeve 22, and the end of the drawing pipe 23 located outside the external sleeve 22 is connected to a negative pressure pump, and the end of the drawing pipe 23 located inside the external sleeve 22 is extended along the external sleeve 22. A high-pressure and high-power negative pressure pump is used to provide negative pressure to the emulsifying cylinder 2, and at the same time, the blocked feed pipe 21 is opened, and the turning plate 31 continuously scoops up the raw materials into the mixing hollow tube 3, and the raw materials entering the mixing hollow tube 3 are extracted through the external sleeve 22.

[0046] When collecting the emulsified raw materials, in order to prevent the raw materials from entering the hot air pipe 24 during the negative pressure reflux process, Figure 2As shown, the end of the hot air pipe 24 located in the outer sleeve 22 is a spherical opening, and a cross bar 25 is fixed to the inner wall of the spherical opening. The cross bar 25 is slidably plugged with a T-shaped slide bar 26. The end of the T-shaped slide bar 26 slides out of the spherical opening and is fixedly connected with a spherical airbag 27. The outer diameter of the spherical airbag 27 is equal to the inner diameter of the spherical opening. When the emulsified raw materials flow back to the height of the spherical airbag 27, the spherical airbag 27 floats up due to the buoyancy to block the spherical opening, so as to ensure that the raw materials in the hot air pipe 24 enter.

[0047] Further, such as Figure 7 As shown, an extension is provided at the end of the shear blade 37, and the extension extends away from the plane where the shear blade 37 is located; a plurality of shear seats 310 are provided on the inner top wall of the mixing hollow tube 3, a plurality of shear teeth 371 are provided on the extension, and the shear seat 310 is provided with a shearing notch matching the shearing teeth 371 of the extension. The raw materials entering the mixing hollow tube 3 are shredded by the shear blade 37 while being able to follow the shearing vortex flow, and are extruded and sheared by the shearing notch in cooperation with the simple shearing teeth 371 of the shear blade 37, thereby accelerating the shearing efficiency of large-particle raw materials. The mixing hollow tube 3 with or without shearing teeth 371 can be selected according to the use requirements, and the purpose of this is to further accelerate the emulsification mixing efficiency.

[0048] like Figure 1 As shown, a protective cover 11 is fixed between the emulsifying cylinder 2 and the motor 1 and is sleeved on the outside of the output end of the motor 1. The protective cover 11 protects the output end of the motor 1 to prevent accidental injury to the operator.

[0049] The present invention also discloses an operating method of a constant temperature emulsifying device for raw materials used in processing plastic bottle caps, comprising the following steps:

[0050] A1, introducing the raw materials of plastic bottle caps and emulsifier into the emulsifying cylinder 2 from the feeding pipe 21;

[0051] A2. The mixing hollow tube 3 is rotated to drive the turning plate 31 to pick up the plastic raw materials and emulsifier in the emulsifying cylinder 2 to turn the materials. The picked-up raw materials are separated from the gap between two adjacent dividing plates 32 and flow back into the emulsifying cylinder 2 again, so that the raw materials at different levels are turned over;

[0052] A3. As the turning plate 31 turns to an inclined state, the picked-up raw materials will quickly enter the mixing hollow tube 3 from the larger opening of the feed inlet 35 along the turning plate 31, and the rotating shear blade 37 will be peeled in the mixing hollow tube 3. The small particles of plastic after peeling can be more fully contacted and fused with the emulsifier. The rotation of the shear blade 37 forms a rotating vortex in the mixing hollow tube 3 in the same direction as the rotation of the shear blade 37, which can drive the peeled raw materials to flow back from the multiple discharge holes 34 to the emulsifying barrel 2, so as to realize the peeling operation of multiple batches and small quantities in the mixing hollow tube 3.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The rotation of the shear blade (37) forms a rotating vortex in the mixing hollow tube (3) in the same direction as the rotation of the shear blade (37), which can drive the peeled raw materials to flow back from the multiple discharge holes (34) to the emulsifying barrel (2), thereby realizing a multi-batch small-volume cyclic peeling operation in the mixing hollow tube (3).
