Description

Technical Field

[0001] The present invention relates to the technical field of graphene floor heating packaging material production, and in particular to a graphene floor heating packaging material production line. Background Art

[0002] Graphene floor heating is a new type of floor heating system that uses graphene as the heating material. The graphene floor heating packaging material selects additives according to the production process formula, and is ground after metering and proportioning. The PVC resin powder is then sieved, and the storage tank and additives are automatically weighed and proportioned before entering a high-speed shear mixer for drying, internal mixing, and open mixing. The material then enters the extrusion hopper for heating, extrusion, and pulling through a mold to obtain a basic sheet. The sheet is then expanded, slowly cooled, and cooled. If necessary, an embossing cooling process is implemented to obtain a semi-finished product.

[0003] During the extrusion molding process of graphene floor heating packaging materials, the extruder feed speed needs to be controlled according to the product extrusion speed or conveying speed. However, when the extrusion speed at the extruder port is reduced or the product conveying speed is reduced, the heating time of the original material in the extruder will increase, causing the melted packaging material to change in quality due to the long heating time, thereby causing the quality of the subsequently extruded product to change. Summary of the Invention

[0004] The object of the present invention is to provide a graphene floor heating packaging material production line, which has the advantage that the quality of the melted packaging material will not change due to excessive heating time caused by changes in extrusion speed.

[0006] The storage mechanism can intermittently communicate with the heating flow channel when it rotates. When the storage mechanism rotates to the bottom of the heating flow channel and communicates with the heating flow channel, the material in the heating flow channel flows into the storage mechanism.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] In order to better understand the graphene floor heating packaging material production line provided by this embodiment, the existing graphene floor heating packaging material production line is briefly introduced below. The extruder needs to select appropriate speed control parameters according to different raw materials to ensure the quality of the extruded finished product. It is also necessary to adjust the discharge control parameters in time according to production needs to meet production requirements. However, when the extrusion speed of the extruder port is reduced or the product conveying speed is reduced, the heating time of the original material in the extruder will increase, resulting in poor quality of the base sheet obtained by extrusion and traction. The specification aims to solve the above technical problems. The embodiment of the present application provides a graphene floor heating packaging material production line to solve the above problems.

[0034] Example 1: Reference Figure 1 - Figure 2, which is the first embodiment of the present invention, provides a graphene floor heating packaging material production line, including a high-speed shear mixer and an extruder 1, the extrusion end of the extruder 1 is connected to an extrusion structure 2, the extrusion structure 2 includes a heating flow channel 21 and a storage mechanism 22 sheathed on the outside of the heating flow channel 21, and the storage mechanism 22 can rotate around the extrusion axis, the discharge port of the extrusion structure 2 is connected to an extrusion die 4, the material enters the high-speed shear mixer, is dried, banburyed, and opened for refining, and then enters the extrusion hopper of the extruder 1 and is extruded by the extruder 1 and the extrusion structure 2 into the extrusion die 4, and is heated and extruded through the extrusion die 4, and pulled to obtain a basic sheet, which is then expanded, slowly cooled, and cooled, and an embossing cooling process is performed if necessary to obtain a semi-finished product, which is then trimmed, curled, inspected, measured, packaged, and stored.

[0035] The storage mechanism 22 can be intermittently communicated with the heating channel 21 when it rotates. When the storage mechanism 22 rotates to the bottom of the heating channel 21 and communicates with the heating channel 21, the material in the heating channel 21 flows into the storage mechanism 22. When the storage mechanism 22 rotates to the top of the heating channel 21 and communicates with the heating channel 21, the material in the storage mechanism 22 flows back into the heating channel 21. A heat-insulating outer cover 23 is provided on the outside of the extrusion structure 2. A driving member 3 for driving the storage mechanism 22 to rotate is provided on the output shaft of the extruder 1. The storage mechanism 22 includes a rotating ring 221 and a storage seat 222. The rotating ring 221 is covered on the outer wall of the heating channel 21. A storage slot is provided in the storage seat 222. The driving member 3 includes a motor and a speed measuring System, the motor is connected to the speed measuring system, and the output end of the motor is connected to the rotating ring 221. The speed measuring system is used to detect the speed of the driving rod of the extruder 1 during extrusion, and start the motor according to the speed of the extruder 1. When the speed of the extruder 1 slows down, the motor drives the rotating ring 221 and the storage seat 222 to rotate to the bottom end of the heating channel 21, and the excess and heated material in the heating channel 21 flows into the storage tank of the storage seat 222, and the material in the storage tank is insulated by the insulation cover 23. When the extruder 1 resumes its speed, the motor drives the rotating ring 221 and the storage seat 222 to rotate to the top of the heating channel 21. At this time, the insulated and stored material in the storage tank flows back to the heating channel 21, and is pulled and extruded by the extrusion die 4 together with the material to obtain a sheet.

[0036] An arc-shaped groove 211 communicating with the storage groove is provided on the outer wall of the heating flow channel 21, and a heater is provided in the heating flow channel 21. By providing a storage mechanism 22, when the extrusion speed is reduced, the melted but unextruded material can be transferred to the storage groove of the storage seat 222. The melted material in the storage groove will not continue to be heated, and the upper end is heat-conducted by the heater, and the lower end and the outer side are insulated by the insulation cover 23. The melted material in the storage groove remains in a flowable state. Then, when the extrusion speed is restored, the storage groove rotates until the stored material flows back to the heating flow channel 21, is mixed with the subsequent melted material, and is extruded together, thereby solving the problem of quality change of the melted packaging material due to excessive heating time caused by changes in the extrusion speed.

[0037] Example 2: Reference Figure 3 - Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment. During the implementation of the first embodiment, it was found that each time the speed of the extruder 1 changes, the detection system needs to be detected before the storage seat 222 can be adjusted. However, the detection system and the extruder 1 speed detection are poor. When an error occurs when driving alone, it affects the function of the extrusion structure 2, and the extrusion structure 2 cannot be driven flexibly and synchronously to adjust at the same time as the extruder 1.

[0038] In order to solve the above problems, this embodiment is provided with a driving member 3 that can synchronously adjust the extrusion structure 2 and the extruder 1. The driving member 3 includes a coupling mechanism 31, a linkage rod 32, a driving gear 33 and a linkage mechanism 34. The output shaft of the extruder 1 is docked with the linkage rod 32 through the coupling mechanism 31. One end of the linkage rod 32 is sleeved with the driving gear 33. The linkage mechanism 34 is sleeved on the outer wall of the storage mechanism 22. The coupling mechanism 31 includes a first coupling 311, a second coupling 312, a third coupling 313 and a docking rod 314. The first coupling 311 is sleeved on the output shaft of the extruder 1, the second coupling 312 is clamped with the first coupling 311, and the second coupling 312 is also clamped with the third coupling 313. The second coupling 312 is sleeved on the output shaft of the extruder 1 through a bent rod, and the third coupling 313 is sleeved on the docking rod 314. The docking rod 314 is docked with the linkage rod 32 through a gear. The driving mechanism 34 includes a linkage gear ring 341, a fixed outer ring 342, a clamp ring 343, a movable inner clamp ring 344 and a connecting ring 345. The linkage gear ring 341 is sleeved on the outer wall of the rotating ring 221. The linkage gear ring 341 is engaged with the driving gear 33. One end of the clamp ring 343 is sleeved on the outer wall of the rotating ring 221 through the connecting ring 345. The outer side of the clamp ring 343 is covered with the fixed outer ring 342. A movable inner clamp ring 344 is provided between the clamp ring 343 and the fixed outer ring 342. The movable inner snap ring 344 and the fixed outer ring 342 have a circle of grooves 3421 on their inner wall, a section of annular teeth 3441 is provided on the outer wall of the movable inner snap ring 344, an eccentric groove 3442 is provided on the movable inner snap ring 344, the movable inner snap ring 344 is covered on the clamp ring 343 through the eccentric groove 3442, a locking notch 3431 is provided on the clamp ring 343, and a locking block that is movably locked with the locking notch 3431 is provided on the inner wall of the eccentric groove 3442.

[0039] The driving member 3 also includes a locking member 35 connected to the output end of the extrusion motor. The locking member 35 includes a telescopic rod 351, an extrusion spring 352, a linkage plate 353, a turntable 354 and a sliding rod 355. A slide groove is provided under the heat insulation outer cover 23, and the telescopic rod 351 is installed in the slide groove. The bottom end of the telescopic rod 351 is vertically connected to the linkage plate 353, and the telescopic rod 351 is covered with an extrusion spring 352. The extrusion spring 352 is provided in the slide groove, and the turntable 354 is sleeved on the output end of the extrusion motor. The output end of the extruder 1 rotates the output shaft of the extruder 1 through a belt. A plurality of supports 3541 are provided outside the turntable 354, each of which is provided with an inner groove for limiting the movement of the sliding rod 355. One end of the sliding rod 355 is connected to a counterweight roller 3551, and the rotation speed and the counterweight roller 3551 are used to cooperate to realize automatic locking and automatic unlocking of the locking member 35.

[0040] The driving member 3 can drive the storage mechanism 22 to rotate when the output shaft of the extruder 1 changes speed, so as to store excess material during deceleration. When the speed is restored, the storage mechanism 22 is driven to rotate and reset, so that the stored material flows back into the heating channel 21. By setting the driving member 3, the driving smoothness is improved, and driving errors caused by single driving errors are avoided. The driving member 3 uses the power extruded by the extruder 1 to adjust the speed of the material in the heating channel 21, thereby reducing additional driving and improving driving flexibility.

[0041] Specifically, the output shaft of the extruder 1 is driven to rotate by the extrusion motor, driving the extruder 1 to extrude. When the extruder 1 rotates rapidly, the output shaft of the extruder 1 drives the first coupling 311 to rotate, and drives the second coupling 312 to revolve around the axis of the output shaft of the extruder 1 through the bending rod, and the second coupling 312 drives the third coupling 313 to rotate when it revolves, and then drives the docking rod 314 to rotate. The docking rod 314 drives the linkage rod 32 to rotate through the gear, and the linkage rod 32 rotates and drives the linkage mechanism 34 to rotate together through the driving gear 33. The driving gear 33 is engaged with the linkage gear ring 341, thereby driving the rotating ring 221 to rotate, thereby driving the storage seat 222 to rotate rapidly. When the storage seat 222 rotates to above the heating flow channel 21, the material inside When the rotating ring 221 drives the clamp ring 343 to rotate, the clamp ring 343 pushes the movable inner clamp ring 344 to rotate together through the locking groove 3431. Under the action of acceleration, the movable inner clamp ring 344 rotates eccentrically so that the inner wall block of the movable inner clamp ring 344 is quickly locked into the locking groove 3431. When the block of the movable inner clamp ring 344 is locked into the locking groove 3431, the annular teeth 3441 on the outer wall of the movable inner clamp ring 344 rotate to the bottom and lock with the locking groove 3421 on the bottom inner wall of the fixed outer ring 342. At this time, the storage seat 222 rotates to the top of the heating flow channel 21 and communicates with the heating flow channel 21, so that the material stored in the storage seat 222 flows back to the heating flow channel 21. In the embodiment, the output shaft of the extruder 1 rotates continuously and rapidly. Since the linkage rod 32 is locked by the linkage mechanism 34 and cannot rotate, at this time, the first coupling 311 rotates to drive the second coupling 312 to revolve. At the same time, the second coupling 312 is limited to rotate by the third coupling 313, and the second coupling 312 revolves and rotates at the same time, which tends to drive the third coupling 313 to rotate, so that the linkage mechanism 34 is always kept in a locked state. When the output shaft of the extruder 1 reduces the speed, the second coupling 312 rotates slower, and the gap between the third coupling 313 and the second coupling 312 becomes larger. The second coupling 312 cannot continue to drive the third coupling 313 to rotate. When there is a gap between the third coupling 313 and the second coupling 312, After the first and second stoppers 313 are in the workpiece 320, the first and second stoppers 313 are in the workpiece 320, and the first and second stoppers 313 are in the workpiece 320. When the first and second stoppers 313 are in the workpiece 320, the first and second stoppers 313 are in the workpiece 320, and the first and second stoppers 313 are in the workpiece 320. When the first and second stoppers 313 are in the workpiece 320, the first and second stoppers 313 are in the workpiece 320.Excess material in the heating channel 21 enters the storage seat 222 for heat preservation and storage. When the extruder motor output resumes speed, the rotation speed of the turntable 354 increases synchronously, and the counterweight roller 3551 is thrown out by centrifugal force and extends above the linkage plate 353, driving the linkage plate 353 downward and then driving the telescopic rod 351 to retract, unlocking the storage seat 222, and the storage seat 222 can be rotated again to above the heating channel 21.

[0042] Example 3: Reference Figure 10 - Figure 11 , which is the third embodiment of the present invention. Different from the second embodiment, this embodiment provides another method of using rotation speed to solve the problem of quality change of molten packaging material due to excessive heating time caused by changes in extrusion speed. The storage mechanism 22 also includes a storage pipe 223 interconnected with the heating flow channel 21. A screw conveyor 224 is provided in the storage pipe 223. A turntable 354 is installed at one end of the linkage rod 32. A plurality of supports 3541 are provided outside the turntable 354. Each support 3541 is provided with an inner groove for limiting the movement of a sliding rod 355. A counterweight roller 3551 is connected to one end of the sliding rod 355. A linkage tooth 2241 is connected to the output rod below the screw conveyor 224 through a coupling structure. The linkage rod 32 has the same rotation speed as the output shaft of the extruder 1. When the output shaft of the extruder 1 rotates at a normal speed, it drives the linkage rod 32 to rotate. When the linkage rod 32 is rotating at a normal speed, the weight of the counterweight roller 3551 can be used to drive the sliding rod 355 to be thrown out, and the swung sliding rod 355 is docked with the gear rod on the linkage tooth 2241, thereby driving the linkage tooth 2241 to rotate, and the linkage tooth 2241 drives the screw conveyor 224 to rotate through the coupling structure, and transports the material in the storage pipe 223 back to the heating flow channel 21. When the output shaft speed of the extruder 1 slows down, the linkage rod 32 slows down synchronously, and the slowed speed cannot drive the sliding rod 355 to be thrown out, and then cannot drive the linkage tooth 2241 to rotate. All screw conveyors 224 stop rotating, and the material accumulated in the heating flow channel 21 flows back to the storage pipe 223 under the action of gravity for heat preservation and storage. The amount of extruded material can be adjusted according to the extrusion speed to ensure that the quality of the molten packaging material will not change due to changes in the extrusion speed, thereby improving the extrusion quality of the substrate.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
