Technical Field

[0001] The invention relates to the technical field of material mixing, in particular to a material mixing device for processing anti-deformation plastic containers. Background Art

[0002] Plastic processing, also known as plastic molding technology, is a general term for various processes that turn synthetic resins or plastics into plastic products. Plastic processing usually includes batching, molding, and modification processes, among which the mixing device is used to mix various raw materials evenly during the batching process, and cross-link and solidify them under a certain temperature and pressure to obtain solid materials or products.

[0003] Although mixers play an important role in plastic processing, there are still some drawbacks and challenges that affect their efficiency and finished product quality, such as the mixing uniformity that does not meet ideal requirements.

[0004] Common mixing devices all use a single stirring method to mix materials, which results in a large number of mixing blind spots in the mixing barrel during the mixing process, so that the plastic raw materials cannot be mixed well, resulting in uneven mixing, which seriously affects the quality of the plastic. Summary of the invention

[0006] As an improvement of the above technical solution, the heating sleeve assembly at least includes a heating tube, an inner lining tube, a reset assembly, and a sealing member; The heating tube has openings at both ends, the through holes are evenly distributed on the wall of the heating tube, and the sealing member is adapted to the opening at the bottom end of the heating tube; The inner lining tube is open at both ends, the inner lining tube is located in the heating tube and slidably cooperates with the heating tube, the reset assembly is evenly embedded on the inner wall of the heating tube and connected to the inner lining tube, and through holes 2 are evenly distributed on the wall of the inner lining tube.

[0007] As an improvement of the above technical solution, when the heating tube is assembled with the sealing member, the reset assembly is compressed by force, and the through hole 1 and the through hole 2 correspond one to one; When the heating tube is separated from the sealing member, the reset assembly is reset, and the through hole 1 and the through hole 2 are staggered one by one.

[0008] As an improvement of the above technical solution, the reset assembly at least includes a self-locking elastic member and a slider; A plurality of slide grooves for placing self-locking elastic members are evenly arranged on the inner wall of the heating cylinder, the slide block is slidably matched with the slide groove, and the inner lining cylinder is connected with the self-locking elastic member through the slide block.

[0009] As an improvement of the above technical solution, the bottom end of the heating cylinder extends out of the mixing barrel, and a power supply plug is provided on the outer wall where the heating cylinder extends out of the mixing barrel. The sealing member is threadedly matched with the heating cylinder, and the sealing member has a handle.

[0010] As an improvement of the above technical solution, the stirring assembly at least includes a spiral shaft, a spiral conveying blade, a ratchet mechanism, a transmission shaft and a separator; The bottom end of the spiral shaft is located in the inner liner and extends to the lower inner side of the inner liner.

[0014] As an improvement of the above technical solution, when the heating tube is separated from the sealing member, the engaging disk 1 and the engaging disk 2 are separated.

[0015] Beneficial effects of the present invention: The stirring component stirs without dead angles and forces the material to circulate on both sides of the heating sleeve component, where it is constantly broken up and gathered, thereby achieving full mixing of the material and making the final material of higher quality.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the prior art, common mixing devices use a single stirring method to mix materials, which results in a large number of stirring blind spots in the mixing barrel during the mixing process, so that the plastic raw materials cannot be mixed well, resulting in uneven mixing, which seriously affects the quality of the plastic.

[0021] See attached Figure 1-Figure 9 As shown, Figure 1 It is a three-dimensional diagram of the overall structure of the present invention; Figure 2 A top view of the overall structure of the present invention; Figure 3 for Figure 2 Sectional view at AA in the middle; Figure 4 is a three-dimensional diagram of the heating sleeve assembly of the present invention; Figure 5 This is a diagram showing the internal structure of the heating sleeve assembly in the present invention; Figure 6 for Figure 5 A partial enlarged view of point E in the middle; Figure 7 It is the overall assembly diagram of the stirring component and the driving part in the present invention; Figure 8 It is a schematic diagram of the internal structure of the stirring assembly in the present invention; Fig. 9 Schematic diagram of the internal structure of the separator in the present invention.

[0022] In order to solve the above technical problems, a mixing device for processing anti-deformation plastic containers is provided, comprising: a mixing barrel 100, a heating sleeve assembly 200, a stirring assembly 300, and a driving unit 400.

[0023] Among them, there are pipe 110 and pipe 2 120 connected to the inner side of the mixing barrel 100 on both sides of the top of the mixing barrel 100, the heating sleeve assembly 200 is located on the inner side of the mixing barrel 100, and the bottom end passes through the bottom surface of the mixing barrel 100 and extends out, and the heating sleeve assembly 200 is evenly distributed with through holes 210 that can be opened or closed. The through holes 210 connect the spaces on both sides of the heating sleeve assembly 200, the stirring assembly 300 is located inside the mixing barrel 100, and is used for stirring and mixing the materials inside the heating sleeve assembly 200 and between the heating sleeve assembly 200 and the mixing barrel 100, and the driving unit 400 is located at the top of the mixing barrel 100 and is connected to the stirring assembly 300 in transmission.

[0024] Specifically, the mixing barrel 100 is a bottom-open structure. Under normal working conditions, pipe 1 110 and pipe 2 120 at the top can not only be used to transport different materials, but also, when necessary, one pipe can be used to transport materials while the other pipe can be used to control the mixing environment inside the mixing barrel 100, so as to be used for mixing materials of different types, kinds and working conditions.

[0025] The heating sleeve assembly 200 is used to heat the mixed materials to melt and mix them. This solution improves the heating sleeve assembly 200, continuously heats the materials during the material mixing process, and the materials are circulated, stirred and dispersed inside and outside the heating sleeve assembly 200 through the through hole 1 210 that can be closed or opened to achieve full and uniform mixing.

[0026] The stirring assembly 300 adopts a spiral structure, which can not only stir without dead angles, but also realize the circulation of materials on both sides of the heating sleeve assembly 200, thereby improving the mixing efficiency. The driving part 400 is connected to the stirring assembly 300 by transmission. In this solution, the driving part 400 can be a conventional motor.

[0027] In this solution, the stirring component 300 stirs without dead angles and forces the material to circulate on both sides of the heating sleeve component 200, and is constantly broken up and gathered, thereby achieving full mixing of the material, so that the final material quality is higher. In order to facilitate understanding of the technical solution of the present application, the heating sleeve assembly 200 is further described. The heating sleeve assembly 200 is mainly used to divide the internal space of the mixing barrel 100 to a certain extent and heat the mixed materials.

[0028] See attached Figure 4 -Attached Figure 5 As shown, Figure 4 is a three-dimensional diagram of the heating sleeve assembly of the present invention; Figure 5 This is a diagram of the internal structure of the heating sleeve assembly in the present invention.

[0029] In one embodiment, the heating sleeve assembly 200 includes a heating sleeve 220 , a liner sleeve 230 , a reset assembly 240 , and a seal 250 .

[0030] The upper and lower ends of the heating tube 220 are both open structures, the through holes 210 are evenly distributed on the wall of the heating tube 220, and the sealing member 250 is adapted to the bottom opening of the heating tube 220.

[0031] The inner lining tube 230 is open at both ends. The inner lining tube 230 is located in the heating tube 220 and slidably cooperates with the heating tube 220. The reset assembly 240 is evenly embedded on the inner wall of the heating tube 220 and connected to the inner lining tube 230. Through holes 260 are evenly distributed on the wall of the inner lining tube 230.

[0032] Specifically, an electric heating wire (not shown in the figure) is pre-buried inside the heating cylinder 220. When in operation, the electric heating wire inside the heating cylinder 220 is energized to convert electrical energy into thermal energy for heating the material.

[0033] The inner lining tube 230 is located inside the heating tube 220 and is clearance-matched with the inner wall of the heating tube 220 , so that the reset assembly 240 can push the inner lining tube 230 to move.

[0034] In normal state, the inner liner 230 is reset under the action of the reset assembly 240. At this time, the positions of through hole 1 210 and through hole 2 260 are staggered, and the spaces on both sides of the heating cylinder 220 cannot be connected through through hole 1 210. It can be understood that when the heating cylinder 220 is separated from the sealing member 250, the reset assembly 240 is no longer subjected to force, thus driving the inner liner 230 to reset, and the reset of the inner liner 230 causes through hole 1 210 and through hole 2 260 to stagger one by one. This situation is mainly used for the discharge of materials after they are fully mixed.

[0035] When the seal 250 is assembled with the heating cylinder 220, the inner liner 230 is pushed by the seal 250, and the reset assembly 240 is compressed. The movement of the position of the inner liner 230 makes the through hole 1 210 correspond to the through hole 2 260. That is, when the heating cylinder 220 is assembled with the seal 250, the reset assembly 240 is compressed, and the through hole 1 210 corresponds to the through hole 2 260. This situation is mainly used for mixing and preheating materials. See attached Figure 6 As shown, Figure 6 for Figure 5 A partial enlarged view of point E in the middle.

[0036] In order to ensure stable movement of the inner liner 230 , a specific implementation of the reset assembly 240 is provided.

[0037] In this embodiment, the reset assembly 240 includes a self-locking elastic member 241 and a sliding block 242 .

[0038] A plurality of slide grooves 243 for accommodating the self-locking elastic member 241 are evenly provided on the inner wall of the heating tube 220 , the slider 242 is slidably matched with the slide groove 243 , and the lining tube 230 is connected to the self-locking elastic member 241 via the slider 242 .

[0039] The slider 242 extends into the slide groove 243, forcing the inner lining tube 230 to move back and forth only along the length direction of the slide groove 243. The self-locking elastic member 241 is self-locking when it is compressed to a certain length (at this time, the through hole 1 210 and the through hole 2 260 correspond one to one). After pressure is applied to the self-locking elastic member 241 again, the inner lining tube 230 is pushed to reset (at this time, the through hole 1 210 and the through hole 2 260 are staggered one by one).

[0040] Furthermore, in order to avoid the heating tube 220 affecting the reset component 240 when heating, the internal electric heating wire is not arranged at the reset component 240, and the reset component 240 is arranged at the upper opening of the heating tube 220 as much as possible.

[0041] To ensure stable power supply to the electric heating wire inside the heating tube 220 , the bottom end of the heating tube 220 extends out of the mixing barrel 100 , and a power plug 270 is provided on the outer wall where the heating tube 220 extends out of the mixing barrel 100 . The sealing member 250 is threadedly matched with the heating tube 220 , and the sealing member 250 has a handle 251 .

[0042] The power supply plug 270 is provided so that the power supply circuit is located inside the heating tube 220, simplifying the circuit. The sealing member 250 is threadedly matched with the heating tube 220, and the sealing member 250 is equivalent to an end cover structure, which can block the bottom opening of the heating tube 220 after being matched with the heating tube 220. The provision of the handle 251 facilitates the assembly operation of the sealing member 250. In order to facilitate understanding of the technical solution of the present application, further description is given to the stirring assembly 300. The stirring assembly 300 is mainly used to stir and mix the materials, and cooperates with the heating cylinder 220 to continuously disperse the stirred materials.

[0043] See attached Figure 7 and Figure 8 As shown, Figure 7 It is the overall assembly diagram of the stirring component and the driving part in the present invention; Figure 8 Schematic diagram of the internal structure of the stirring assembly in the present invention.

[0044] In combination with the foregoing, the stirring assembly 300 includes a spiral shaft 310 , a spiral conveying blade 320 , a ratchet mechanism 330 , a transmission shaft 340 and a separator 350 .

[0045] Among them, the bottom end of the spiral shaft body 310 is located in the inner liner tube 230 and extends to the lower inner side of the inner liner tube 230 , and the spiral conveying blade 320 is located between the heating tube 220 and the mixing barrel 100 .

[0046] The top end of the spiral shaft body 310 is connected to the transmission shaft 340 through the separator 350 , and the top end of the spiral conveying blade 320 is connected to the transmission shaft 340 through the ratchet mechanism 330 .

[0047] The spiral shaft 310 and the inner liner 230 are clearance-matched, and the material in the inner liner 230 can be stirred without dead angles when rotating.

[0048] The ratchet mechanism 330 is provided in consideration of the fact that neither the pipe 1 110 nor the pipe 2 120 is used to transport materials, but is only used to adjust the internal environment of the mixing barrel 100 during mixing. When transporting materials from the bottom opening of the heating barrel 220, it can be achieved by the reverse rotation of the spiral shaft 310. At this time, due to the existence of the ratchet mechanism 330, the spiral transport blade 320 does not rotate with the spiral shaft 310, so the spiral shaft 310 can transport the materials to the space between the heating barrel 220 and the mixing barrel 100.

[0049] Specifically, the working process can be divided into the following steps: Loading process: The heating cylinder 220 is assembled with the sealing member 250, the bottom end of the heating cylinder 220 is closed, the pipe 1 110 or the pipe 2 120 is opened, and materials are added into the mixing barrel 100. At this time, the driving unit 400 drives the stirring assembly 300 to rotate to stir the materials. At the same time, the electric heating wire inside the heating cylinder 220 is powered.

[0050] Stirring and mixing process: The heating cylinder 220 is assembled with the sealing member 250, the bottom end of the heating cylinder 220 is closed, and the pipe 1 110 or the pipe 2 120 no longer adds materials to the mixing barrel 100. At this time, the driving unit 400 drives the stirring assembly 300 to rotate to stir the materials. At the same time, the electric heating wire inside the heating cylinder 220 is powered.

[0051] At this time, through hole one 210 and through hole two 260 correspond one to one, and the material is squeezed out of through hole one 210 to the outside of the heating cylinder 220 under the conveyance of the spiral shaft 310, and the spiral conveying blade 320 lifts the material from the outside of the heating cylinder 220, and then drops it into the heating cylinder 220 from the upper end of the heating cylinder 220, and this cycle repeats.

[0052] The material is broken up when passing through the through hole 1 210, and then is fused in the heating cylinder 220, and then broken up again, and the above process is repeated.

[0053] Discharging process: The power supply circuit of the electric heating wire inside the heating tube 220 is cut off, and then the heating tube 220 is separated from the sealing member 250, so that the bottom opening of the heating tube 220 is opened, and the driving unit 400 drives the spiral shaft 310 to rotate to realize the extrusion of the material.

[0054] Furthermore, in order to avoid residual material between the heating cylinder 220 and the mixing barrel 100 during discharge, the through hole 210 is closed before the spiral shaft 310 extrude the material, and the spiral conveying blade 320 operates alone to convey the material to the heating cylinder 220, and then the spiral shaft 310 completely extrude the material to avoid material residue.

[0055] When the spiral conveying blade 320 works alone, the separator 350 disconnects the spiral shaft body 310 from the transmission shaft 340. At this time, the driving unit 400 drives the spiral conveying blade 320 to rotate only through the transmission shaft 340.

[0056] When the heating cylinder 220 and the sealing member 250 are assembled, the spiral shaft 310 drives the spiral conveying blade 320 to rotate synchronously. When the spiral shaft 310 rotates, the material is squeezed out of the heating cylinder 220 from the through hole 1 210 and the through hole 2 260 , and the spiral conveying blade 320 delivers the material squeezed out of the heating cylinder 220 from the upper end of the heating cylinder 220 to the inside of the heating cylinder 220 .

[0057] Similarly, when the heating cylinder 220 is separated from the sealing member 250 , the spiral shaft 310 rotates and sends the material out of the mixing barrel 100 from the liner cylinder 230 . See attached Fig. 9 As shown, Fig. 9 Schematic diagram of the internal structure of the separator in the present invention.

[0058] In combination with the foregoing, a specific structure of the separator 350 is given.

[0059] The separator 350 includes a driving rod body 351 , an engaging disk 1 352 , and an engaging disk 2 353 .

[0060] The driving rod body 351 is embedded at the bottom end of the transmission shaft 340 , and the end of the driving rod body 351 extending out of the transmission shaft 340 is connected to the meshing disk 1 352 , and the meshing disk 1 352 is adapted to the meshing disk 2 353 fixed on the top end of the spiral shaft body 310 .

[0061] The length of the driving rod 351 is adjustable. When the driving rod 351 is extended, the meshing disc 1 352 and the meshing disc 2 353 cooperate to realize the transmission connection between the transmission shaft 340 and the spiral shaft 310. When the driving rod 351 is shortened, the meshing disc 1 352 and the meshing disc 2 353 cooperate and separate, and the transmission shaft 340 and the spiral shaft 310 are disconnected.

[0062] When the heating cylinder 220 is separated from the sealing member 250 , the material is in the discharging process, that is, the spiral conveying blade 320 is in the independent motion process. At this time, the meshing disc 1 352 and the meshing disc 2 353 are separated, and the transmission shaft 340 only drives the spiral conveying blade 320 to move, thereby realizing the transfer of the material into the heating cylinder 220 .

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
