Description

Technical Field

[0001] The present invention relates to the technical field of low-density polyethylene resin production, in particular to a low-density polyethylene resin production and processing device and a processing method thereof. Background Art

[0002] During the production of low-density polyethylene resin, stirring equipment is required to uniformly mix the resin raw materials. Currently, most of the stirring equipment used is a disc turbine agitator, which uses a disc to support the blades to enhance structural strength and utilizes centrifugal force to achieve efficient dispersion and mixing.

[0003] However, after mixing, resin will adhere to the outside of the disc. Even if the agitator rotates and uses centrifugal force to dislodge some of the resin, the outer blades will block the resin and the viscosity of the resin makes it impossible to completely remove the resin accumulated on the top. Therefore, the residual resin is usually directly washed away with water or manually scraped with a scraper. The former results in a large amount of resin waste, while the latter is difficult and inefficient. Summary of the Invention

[0004] The invention discloses a low-density polyethylene resin production and processing device and a processing method thereof, aiming to solve the technical problems of generally directly washing with water or manually scraping off residual resin with a scraper, the former causing a large amount of resin waste, and the latter being difficult to operate and having low work efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A low-density polyethylene resin production and processing device includes an L-shaped stand and further includes: a drive seat fixedly connected to the L-shaped stand, and an output end of the drive seat is fixedly connected to a rotating shaft, the drive seat being used to drive the rotating shaft to rotate and rise and fall; a turntable fixedly connected to the bottom outer wall of the rotating shaft, and a plurality of blades fixedly connected to the circumferential outer wall of the turntable at equal intervals, with adjacent blades arranged in an upper and lower staggered manner; a top cleaning mechanism movably connected to the top outer wall of the turntable; a bottom cleaning mechanism movably connected to the bottom outer wall of the turntable; and a limit mechanism arranged on one side of the bottom cleaning mechanism.

[0007] The top cleaning mechanism includes: an annular scraper, movably sleeved on the outside of the circumference of the rotating shaft; a C-shaped guide groove, fixedly connected to the outer wall of one side of the annular scraper, and a gap is set between the bottom end of the C-shaped guide groove and the top of the turntable, one side of the C-shaped guide groove is fixedly connected to an oblique guide groove, and the oblique guide groove is located at the top of the blade; an inclined scraper, fixedly connected to one side of the C-shaped guide groove, and its bottom end is movably fitted to the top outer wall of the turntable, and the annular scraper, C-shaped guide groove, oblique guide groove and inclined scraper are fixed in height;

[0008] The top cleaning mechanism further comprises: a sleeve frame, movably sleeved on the circumferential outer wall of the rotating shaft 1, and fixedly connected to the top outer wall of the annular scraper; a horizontal plate, fixedly connected to the top outer wall of the sleeve frame; a second insertion rod, movably inserted into the horizontal plate, and having a circular support plate 3 fixedly connected to its top;

[0009] The top cleaning mechanism also includes: an L-shaped stand three, fixedly connected to the top outer wall of the horizontal plate; a pressure sensing plate, fixedly installed on the L-shaped stand three, and a circular support plate three movably fitted to the sensing end of the pressure sensing plate; and a motor support frame, fixedly connected to one end of the horizontal plate.

[0010] By providing a top cleaning mechanism, after mixing is completed, the turntable is lifted up, and its top outer wall contacts the bottom of the inclined scraper. The annular scraper pushes the residual resin on the rotating shaft to fall to the top outer wall of the turntable. Then the turntable rotates along the bottom end of the inclined scraper. During the rotation, the inclined scraper pushes the residual resin, and as the resin accumulates, it climbs inside the inclined guide groove until it is discharged from the outlet of the inclined guide groove, thereby crossing the outer blades, effectively avoiding the blades from blocking the resin, and realizing the cleaning of the residual resin on the top of the turntable, reducing the waste of resin.

[0011] In a preferred embodiment, the bottom end of the L-shaped stand 1 is fixedly connected to the base, the top outer wall of the base is fixedly connected to the L-shaped stand 2, and the L-shaped stand 2 is fixedly connected to the motor support frame, and the top outer wall of the base is clamped with the tank body.

[0012] In a preferred embodiment, the limiting mechanism includes: a mounting frame fixedly connected to the top outer wall of the motor support frame, and a hydraulic rod fixedly connected to the mounting frame; a U-shaped support frame fixedly connected to the output end of the hydraulic rod, and a circular support plate 1 fixedly connected to the bottom end of the U-shaped support frame; a circular support plate 2, arranged directly below the circular support plate 1;

[0013] The limiting mechanism also includes: an insertion rod 1, which is fixedly connected to the top outer wall of the circular support plate 2 and movably inserted into the circular support plate 1; a spring, which surrounds the outside of the insertion rod 1, and its two ends are respectively fixedly connected to the circular support plate 1 and the circular support plate 2; a pressure plate, which is fixedly connected to one end of the rotating shaft 2, and the circular support plate 2 is movably fitted to the top of the pressure plate.

[0014] By setting a limit mechanism, after scraper 1 moves to the bottom of the turntable, the hydraulic rod is activated to ensure that scraper 1 is stably attached to the bottom end of the turntable, avoiding the connection position between the lower synchronous belt and synchronous pulleys 1 and 2 becoming slightly loose after long-term use, which may affect the lifting position of scraper 1, further ensuring the cleaning effect of the bottom of the turntable.

[0015] In a preferred embodiment, the bottom cleaning mechanism includes: a hinged seat fixedly connected to the outer wall of the bottom end of the motor support frame, and a second rotating shaft is hingedly connected to the hinged seat; a scraper 1 fixedly connected to the outer wall of the second rotating shaft and movably fitted to the outer wall of the bottom end of the turntable; a synchronous wheel 1 fixedly connected to one end of the second rotating shaft;

[0016] The bottom cleaning mechanism also includes: a motor, which is fixedly connected to the inner wall of the motor support frame, and the output end of the motor passes through the motor support frame and is fixedly connected to the second synchronous wheel; a synchronous belt, which is simultaneously sleeved on the outside of the first synchronous wheel and the second synchronous wheel.

[0017] By providing a bottom cleaning mechanism, when the upward position of the turntable is determined based on the sensing signal of the pressure sensing plate, the vertical scraper located on one side can be driven to rotate until the scraper is movably fitted to the bottom outer wall of the turntable. Therefore, during the rotation and top cleaning process of the turntable, the adhered resin can be assisted to separate from the bottom of the turntable, thereby realizing the synchronous cleaning and collection of the resin at the bottom of the turntable.

[0018] A processing method for a low-density polyethylene resin production and processing device comprises the following specific steps:

[0019] S1: The drive seat drives the turntable down into the tank, and the rotation drives the resin raw materials in the tank to mix;

[0020] S2: After mixing is completed, the turntable is lifted up, and the lifting position is determined by pressing the second rod on the pressure sensing plate;

[0021] S3: The motor starts, driving the scraper 1 to fit against the outer wall of the bottom end of the turntable, and then the position of the scraper 1 is limited by the limit mechanism;

[0022] S4: The turntable rotates again, and the top cleaning mechanism and the bottom cleaning mechanism clean and guide the resin remaining on the top and bottom of the turntable respectively, so that the resin falls into the tank body and is recycled.

[0023] As can be seen from the above, a low-density polyethylene resin production and processing device includes an L-shaped stand and further includes: a drive seat, fixedly connected to the L-shaped stand, and the output end of the drive seat is fixedly connected to the rotating shaft, and the drive seat is used to drive the rotating shaft to rotate and lift; a turntable, fixedly connected to the bottom outer wall of the rotating shaft, and the circumferential outer wall of the turntable is fixedly connected to a plurality of blades at equal intervals, and two adjacent blades are arranged in an upper and lower staggered manner; a top cleaning mechanism, movably connected to the top outer wall of the turntable; a bottom cleaning mechanism, movably connected to the bottom outer wall of the turntable; a limiter The structure is arranged on one side of the bottom cleaning mechanism; the top cleaning mechanism includes: an annular scraper, movably sleeved on the outside of the circumference of the rotating shaft; a C-shaped guide groove, fixedly connected to the outer wall of one side of the annular scraper, and a gap is set between the bottom end of the C-shaped guide groove and the top of the turntable, and one side of the C-shaped guide groove is fixedly connected to an oblique guide groove, and the oblique guide groove is located at the top of the blade; an inclined scraper, fixedly connected to one side of the C-shaped guide groove, and its bottom end is movably fitted to the top outer wall of the turntable, and the setting height of the annular scraper, C-shaped guide groove, oblique guide groove and inclined scraper is fixed.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The present invention discloses a low-density polyethylene resin production and processing device and a processing method thereof, which are mainly used in resin processing scenarios.

[0032] Reference Figure 1 and Figure 2 A low-density polyethylene resin production and processing device includes an L-shaped stand 2 and further includes:

[0033] The drive base 1 is fixedly connected to the L-shaped stand 2, and the output end of the drive base 1 is fixedly connected to the rotating shaft 9. The drive base 1 is used to drive the rotating shaft 9 to rotate and rise and fall;

[0034] The turntable 7 is fixedly connected to the outer wall of the bottom end of the rotating shaft 9, and a plurality of blades 10 are fixedly connected to the outer wall of the circumference of the turntable 7 at equal intervals, and two adjacent blades 10 are staggered in an up-and-down manner;

[0035] A top cleaning mechanism 8 is movably connected to the top outer wall of the turntable 7;

[0036] The bottom cleaning mechanism 4 is movably connected to the outer wall of the bottom end of the turntable 7;

[0037] The limiting mechanism 3 is arranged on one side of the bottom cleaning mechanism 4;

[0038] The top cleaning mechanism 8 comprises:

[0039] The annular scraper 801 is movably sleeved on the outer circumference of the rotating shaft 9. The driving seat 1 drives the rotating shaft 9 to rotate and rise and fall, and the resin is mixed by the rotation of the turntable 7. After the mixing is completed, the turntable 7 is lifted up, and its top outer wall contacts the bottom of the inclined scraper 809. During the whole process, the inner wall of the annular scraper 801 is in contact with the circumferential outer wall of the rotating shaft 9, pushing the resin remaining on the rotating shaft 9 to fall to the top outer wall of the turntable 7;

[0040] A C-shaped guide groove 808 is fixedly connected to the outer wall of one side of the annular scraper 801, and a gap is provided between the bottom end of the C-shaped guide groove 808 and the top end of the rotary disc 7. One side of the C-shaped guide groove 808 is fixedly connected to an oblique guide groove 807, and the oblique guide groove 807 is located at the top end of the blade 10;

[0041] The inclined scraper 809 is fixedly connected to one side of the C-shaped guide groove 808, and its bottom end is movably fitted to the outer wall of the top end of the turntable 7. The setting heights of the annular scraper 801, the C-shaped guide groove 808, the inclined guide groove 807 and the inclined scraper 809 are fixed. The turntable 7 rotates along the bottom end of the inclined scraper 809. During the rotation, the inclined scraper 809 pushes the residual resin to accumulate in the C-shaped guide groove 808, and as the resin accumulates, it gradually transfers to the inclined guide groove 807 and climbs inside it until it is discharged from the outlet of the inclined guide groove 807, thereby crossing the outer blade 10, effectively preventing the blade 10 from blocking the resin, thereby cleaning the residual resin on the top of the turntable 7 and reducing resin waste. At the same time, since a gap is provided between the bottom end of the C-shaped guide groove 808 and the top end of the turntable 7, it can prevent the turntable 7 from being squeezed on the accumulated resin during the lifting process, resulting in the inclined scraper 809 being unable to fit the top end of the turntable 7.

[0042] Reference Figure 2 In a preferred embodiment, the top cleaning mechanism 8 further comprises:

[0043] The sleeve 802 is movably sleeved on the circumferential outer wall of the rotating shaft 9 and fixedly connected to the top outer wall of the annular scraper 801;

[0044] The horizontal plate 803 is fixedly connected to the top outer wall of the sleeve frame 802;

[0045] The second insertion rod 806 is movably inserted into the horizontal plate 803, and the top end thereof is fixedly connected to the third circular support plate.

[0046] Reference Figure 2 and Figure 3 In a preferred embodiment, the top cleaning mechanism 8 further comprises:

[0047] L-shaped stand 805, fixedly connected to the top outer wall of the horizontal plate 803;

[0048] The pressure sensing plate 804 is fixedly mounted on the third L-shaped stand 805, and the third circular support plate is movably fitted to the sensing end of the pressure sensing plate 804. When the turntable 7 is lifted, its top end presses the second insertion rod 806 upward until its top end contacts the pressure sensing plate 804, thereby monitoring the lifting position and facilitating the control of the opening and closing of the bottom cleaning mechanism 4 and the lifting positioning of the turntable 7 before the top cleaning.

[0049] The motor support frame 810 is fixedly connected to one end of the horizontal plate 803 .

[0050] Reference Figure 1 In a preferred embodiment, the bottom end of the L-shaped stand 2 is fixedly connected to the base 5, the top outer wall of the base 5 is fixedly connected to the L-shaped stand 2 11, and the L-shaped stand 2 11 is fixedly connected to the motor support frame 810, and the top outer wall of the base 5 is clamped with the tank body 6.

[0051] Reference Figure 3 In a preferred embodiment, the bottom cleaning mechanism 4 includes:

[0052] The hinge seat 404 is fixedly connected to the outer wall of the bottom end of the motor support frame 810, and the hinge seat 404 is hinged with a second rotating shaft 403;

[0053] The scraper 1 401 is fixedly connected to the outer wall of the second rotating shaft 403 and is movably attached to the outer wall of the bottom end of the rotating disk 7;

[0054] The synchronous wheel 1 402 is fixedly connected to one end of the rotating shaft 2 403 .

[0055] Reference Figure 3 In a preferred embodiment, the bottom cleaning mechanism 4 further comprises:

[0056] The motor 407 is fixedly connected to the inner wall of the motor support frame 810, and the output end of the motor 407 passes through the motor support frame 810 and is fixedly connected to the second synchronous wheel 406;

[0057] The synchronous belt 405 is simultaneously sleeved on the outside of the synchronous wheel 1 402 and the synchronous wheel 2 406. When the lifting position of the turntable 7 is determined based on the sensing signal of the pressure sensing plate 804, the synchronous wheel 2 406 can be driven to rotate by the motor 407, and the synchronous wheel 1 402 can be driven to rotate by the linkage of the synchronous belt 405, thereby driving the vertical scraper 1 401 located on one side to rotate around the rotating shaft 2 403 as the axis until the scraper 1 401 is movably fitted to the bottom outer wall of the turntable 7. Therefore, during the rotation and top cleaning process of the turntable 7, the scraper 1 401 also acts on the bottom outer wall of the turntable 7, which can help the adhered resin to separate from the bottom of the turntable 7, thereby realizing the synchronous cleaning and collection of the resin at the bottom of the turntable 7.

[0058] Reference Figure 4In a preferred embodiment, the limiting mechanism 3 includes:

[0059] The mounting frame 301 is fixedly connected to the top outer wall of the motor support frame 810, and the hydraulic rod 302 is fixedly connected to the mounting frame 301;

[0060] A U-shaped support frame 303 is fixedly connected to the output end of the hydraulic rod 302, and a circular support plate 1 304 is fixedly connected to the bottom end of the U-shaped support frame 303;

[0061] The second circular support plate 307 is disposed directly below the first circular support plate 304 .

[0062] Reference Figure 4 In a preferred embodiment, the limiting mechanism 3 further includes:

[0063] Insertion rod 1 305 is fixedly connected to the top outer wall of circular support plate 2 307 and movably inserted into circular support plate 1 304;

[0064] Spring 306 surrounds the outside of the insertion rod 1 305, and its two ends are fixedly connected to the circular support plate 1 304 and the circular support plate 2 307 respectively;

[0065] The pressure plate 308 is fixedly connected to one end of the rotating shaft 2 403, and the circular support plate 2 307 is movably fitted to the top of the pressure plate 308. After the scraper 1 401 moves to the bottom of the turntable 7, the hydraulic rod 302 is started to push down the circular support plate 1 304 so that the circular support plate 2 307 fits the top of the pressure plate 308. This ensures that the scraper 1 401 is stably fitted to the bottom end of the turntable 7, avoiding the connection position of the lower synchronous belt 405 and the synchronous wheel 1 402 and the synchronous wheel 2 406 to become slightly loose after long-term use, affecting the lifting position of the scraper 1 401, further ensuring the cleaning effect of the bottom of the turntable 7, and based on the buffering effect of the spring 306, while ensuring that the hydraulic rod 302 provides sufficient pressure, it also avoids deformation of the scraper 1 401 caused by excessive pressure.

[0066] Reference Figure 5 A processing method for a low-density polyethylene resin production and processing device comprises the following specific steps:

[0067] S1: The driving seat 1 drives the turntable 7 to descend into the tank body 6, and the resin raw materials in the tank body 6 are mixed by the rotation;

[0068] S2: After mixing is completed, the turntable 7 is lifted up, and the lifting position is determined by the second insertion rod 806 pressing on the pressure sensing plate 804;

[0069] S3: The motor 407 is started, driving the scraper 1 401 to fit against the outer wall of the bottom end of the rotary disk 7, and then the position of the scraper 1 401 is limited by the limiting mechanism 3;

[0070] S4: The turntable 7 rotates again, and the top cleaning mechanism 8 and the bottom cleaning mechanism 4 clean and guide the resin remaining on the top and bottom of the turntable 7 respectively, so that the resin falls into the tank body 6 and is recycled.

[0071] Working principle: When in use, the driving seat 1 drives the rotating shaft 9 to rotate and rise and fall, and the resin is mixed by the rotation of the turntable 7. After the mixing is completed, the turntable 7 is lifted up, and its top outer wall contacts the bottom of the inclined scraper 809. During the whole process, the inner wall of the annular scraper 801 is in contact with the circumferential outer wall of the rotating shaft 9, pushing the residual resin on the rotating shaft 9 to fall to the top outer wall of the turntable 7. Then the turntable 7 rotates along the bottom end of the inclined scraper 809. During the rotation, the inclined scraper 809 pushes the residual resin to accumulate in the C-shaped guide groove 8 08, and as the resin accumulates, it gradually transfers to the inclined guide groove 807 and climbs inside it until it is discharged from the outlet of the inclined guide groove 807, thereby crossing the outer blade 10, effectively avoiding the blade 10 from blocking the resin, and realizing the cleaning of the residual resin on the top of the turntable 7, reducing the waste of resin. At the same time, since a gap is provided between the bottom end of the C-shaped guide groove 808 and the top end of the turntable 7, it can avoid being squeezed on the accumulated resin during the lifting process of the turntable 7, resulting in the inclined scraper 809 being unable to fit on the top end of the turntable 7.

[0072] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
