Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rubber and plastic pipe processing technology, and more specifically, to a rubber and plastic insulation pipe open mill. Background Technology

[0002] Rubber and plastic pipes are flexible pipe products made primarily of rubber and plastic through processes such as blending, extrusion, or vulcanization. They combine the high elasticity and aging resistance of rubber with the corrosion resistance and easy processing properties of plastics, and are widely used in construction, automobiles, machinery, and other fields. The products have excellent temperature resistance, UV resistance, insulation, flame retardancy, and shock absorption and noise reduction functions. They are especially suitable for the transportation of hot and cold media, electrical wire protection, and hydraulic systems. The surface is often a closed-cell foam structure, which effectively isolates water vapor, saves energy and is environmentally friendly. No additional insulation layer is required during installation, making it a lightweight alternative to traditional metal pipes.

[0003] In the current technology, operators often use open mills to mix raw materials during the processing of rubber and plastic insulation pipes. However, although existing open mills have basic mixing functions, the fixed position of the mixing blades during mixing results in some areas being insufficiently mixed, which prolongs the mixing time and reduces the mixing efficiency. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rubber and plastic insulation pipe open mill, which solves the technical problem of poor stirring effect in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a rubber and plastic insulation pipe open mixing mill, including a mixing drum, a support base fixedly connected to the top of the mixing drum, a first motor fixedly installed inside the support base, a first rotating shaft fixedly sleeved at the other end of the output shaft of the first motor, a rotating rod fixedly sleeved at the other end of the output shaft of the first rotating shaft, a sleeve rod movably connected to the outer surface of the rotating rod, a vertical plate fixedly connected to the top of the sleeve rod, a movable plate fixedly connected to the top of the vertical plate, and fixed plates fixedly connected to the left and right sides of the top of the mixing drum, the interior of the fixed plate being movably connected to the outer surface of the movable plate.

[0006] As a preferred technical solution of this disclosure, a second motor is fixedly installed on the top of the movable plate, and a second rotating shaft is fixedly sleeved on the other end of the output shaft of the second motor.

[0007] As a preferred technical solution of this disclosure, the other end of the second rotating shaft passes through the movable plate and the mixing cylinder in sequence and extends into the interior of the mixing cylinder and is movably sleeved with the interior of the movable plate and the mixing cylinder. The outer surface of the second rotating shaft is fixedly sleeved with a stirring blade located in the inner cavity of the mixing cylinder.

[0008] As a preferred technical solution of this disclosure, a feeding plate is fixedly installed at the bottom of the inner cavity of the mixing cylinder, a connecting frame is fixedly installed at the bottom of the mixing cylinder, a discharge box is fixedly connected to the bottom of the connecting frame, a drive motor is fixedly connected to the left side of the discharge box, and a rotating rod is fixedly sleeved at the other end of the output shaft of the drive motor.

[0009] As a preferred technical solution of this disclosure, the other end of the rotating rod passes through the discharge box and extends to the outside of the discharge box and is movably connected to the inside of the discharge box, and a spiral plate is fixedly connected to the outer surface of the rotating rod.

[0010] As a preferred technical solution of this disclosure, a power motor is fixedly connected to the left side of the connecting frame, a rotating rod is fixedly sleeved at the other end of the output shaft of the power motor, and a gear is fixedly sleeved at the other end of the rotating rod.

[0011] As a preferred embodiment of this disclosure, the top and bottom of the outer surface of the gear are meshed with toothed plates, the other end of the toothed plates is fixedly connected to a connecting plate, and the inner side of the connecting plate is fixedly connected to a telescopic rod.

[0012] As a preferred embodiment of this disclosure, the other end of the telescopic rod passes through the connecting frame and extends into the interior of the connecting frame and is movably connected to the inner surface of the connecting frame.

[0013] As a preferred technical solution of this disclosure, the left and right sides of the connecting frame are fixedly connected to limit plates, and the outer surface of the limit plates is movably sleeved with the inside of the connecting plates.

[0014] As a preferred embodiment of this disclosure, the outer surface of the telescopic rod is rectangular and smooth.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. This disclosure incorporates a rotating rod, a sleeve rod, a vertical plate, a movable plate, and a fixed plate. When the first motor starts running, the first rotating shaft drives the rotating rod to rotate, and the rotating rod presses and pushes the sleeve rod. At this time, the sleeve rod drives the vertical plate to move, thereby allowing the movable plate to move vertically upward under the limiting action of the fixed plate. Ultimately, the movable plate drives the second rotating shaft and the stirring blade to move up and down, realizing the function of adjusting the height position of the stirring blade, avoiding insufficient mixing in some areas, and improving the efficiency of the mixing operation.

[0017] 2. This disclosure includes a toothed plate, a pusher plate, a limiting plate, and a [missing information]. When the power motor is started, the rotating rod drives the gear to rotate, causing the two toothed plates to move horizontally in opposite directions under the limiting action of the limiting plate. Ultimately, the two pusher plates move horizontally towards each other under the limiting action of the limiting plate, thus pushing the raw material scattered at the bottom of the connecting frame into the discharge box. This achieves the function of adjusting the discharge rate and prevents the raw material from falling directly into the discharge box after passing through the discharge plate, which would result in excessive discharge volume and cause discharge difficulties.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0031] like Figures 1-5 As shown, a rubber and plastic insulation pipe open mixing mill according to an embodiment of the present disclosure is illustrated, including a mixing drum 1. A support base 2 is fixedly connected to the top of the mixing drum 1. A first motor 3 is fixedly installed inside the support base 2. A first rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. A rotating rod 5 is fixedly sleeved at the other end of the output shaft of the first rotating shaft 4. A sleeve rod 6 is movably connected to the outer surface of the rotating rod 5. A vertical plate 7 is fixedly connected to the top of the sleeve rod 6. A movable plate 8 is fixedly connected to the top of the vertical plate 7. Fixed plates 9 are fixedly connected to the left and right sides of the top of the mixing drum 1. The interior of the fixed plate 9 is movably connected to the outer surface of the movable plate 8.

[0032] When the first motor 3 starts running, it will cause the first rotating shaft 4 to rotate together with the rotating rod 5, and the rotating rod 5 will squeeze and push the sleeve rod 6. At this time, the sleeve rod 6 will drive the vertical plate 7 to move, so that the movable plate 8 can move vertically upward under the limiting action of the fixed plate 9.

[0033] In some examples, a second motor 10 is fixedly mounted on the top of the movable plate 8, and a second rotating shaft 11 is fixedly sleeved on the other end of the output shaft of the second motor 10.

[0034] When the second motor 10 starts running, it will cause the second rotating shaft 11 to rotate.

[0035] In some examples, the other end of the second rotating shaft 11 passes through the movable plate 8 and the mixing cylinder 1 in sequence and extends into the interior of the mixing cylinder 1 and is movably sleeved with the interior of the movable plate 8 and the mixing cylinder 1. The outer surface of the second rotating shaft 11 is fixedly sleeved with a stirring blade 12 located in the inner cavity of the mixing cylinder 1.

[0036] When the second rotating shaft 11 starts to rotate, it will drive the stirring blade 12 to rotate as well.

[0037] In some examples, a feeding plate 13 is fixedly installed at the bottom of the inner cavity of the mixing cylinder 1, a connecting frame 14 is fixedly installed at the bottom of the mixing cylinder 1, a discharge box 15 is fixedly connected to the bottom of the connecting frame 14, a drive motor 16 is fixedly connected to the left side of the discharge box 15, and a rotating rod 17 is fixedly sleeved at the other end of the output shaft of the drive motor 16.

[0038] When the drive motor 16 starts running, it will cause the rotary rod 17 to rotate.

[0039] In some examples, the other end of the rotating rod 17 passes through the discharge box 15 and extends to the outside of the discharge box 15 and is movably connected to the inside of the discharge box 15. A spiral plate 18 is fixedly connected to the outer surface of the rotating rod 17.

[0040] When the rotary rod 17 starts to rotate, it will drive the spiral plate 18 to rotate as well, and send the mixed raw materials out of the device.

[0041] In some examples, a power motor 19 is fixedly connected to the left side of the connecting frame 14, and a rotating rod 20 is fixedly sleeved at the other end of the output shaft of the power motor 19, and a gear 21 is fixedly sleeved at the other end of the rotating rod 20.

[0042] When the power motor 19 starts running, it will cause the rotating rod 20 to drive the gear 21 to rotate.

[0043] In some examples, the top and bottom of the outer surface of the gear 21 are meshed with toothed plates 22, the other end of the toothed plates 22 is fixedly connected to a connecting plate 23, and the inner side of the connecting plate 23 is fixedly connected to a telescopic rod 24.

[0044] When gear 21 rotates, it will cause the two toothed plates 22 to drive the two connecting plates 23 and the two telescopic rods 24 to move in opposite directions.

[0045] In some examples, the other end of the telescopic rod 24 passes through the connecting frame 14 and extends into the interior of the connecting frame 14 and is movably connected to the inner surface of the connecting frame 14. A pusher plate 25 is fixedly connected to the inner side of the telescopic rod 24, and the outer surface of the pusher plate 25 is movably connected to the interior of the connecting frame 14.

[0046] When the two telescopic rods 24 move, the two pusher plates 25 will move horizontally towards each other under the limiting action of the connecting frame 14.

[0047] In some examples, limiting plates 26 are fixedly connected to both the left and right sides of the connecting frame 14, and the outer surface of the limiting plates 26 is movably sleeved with the inside of the connecting plate 23.

[0048] Due to the limiting effect of the limiting plate 26, the toothed plate 22 can only move horizontally left and right, driving the connecting plate 23.

[0049] In some examples, the outer surface of the telescopic rod 24 is rectangular and smooth.

[0050] This design allows the telescopic rod 24 to move more smoothly inside the connecting frame 14, reduces the friction between the telescopic rod 24 and the connecting frame 14, and improves the service life of the telescopic rod 24.

[0051] The working principle and usage process of this disclosure are as follows:

[0052] After adding the raw materials, the second motor 10 is started, causing the second rotating shaft 11 to drive the stirring blade 12 to rotate. At the same time, the first motor 3 is started, causing the first rotating shaft 4 to drive the rotating rod 5 to rotate together. The rotating rod 5 then presses and pushes the sleeve rod 6. At this time, the sleeve rod 6 will drive the vertical plate 7 to move, so that the movable plate 8 moves vertically upward under the limiting action of the fixed plate 9. Finally, the movable plate 8 drives the second rotating shaft 11 and the stirring blade 12 to move up and down, realizing the function of adjusting the height position of the stirring blade 12, avoiding insufficient mixing in some areas, and improving the efficiency of the mixing operation.

[0053] After the mixed raw materials fall into the inner cavity of the connecting frame 14 through the feeding plate 13, the drive motor 16 is started, causing the rotating rod 17 to drive the spiral plate 18 to rotate. Finally, the mixed raw materials are discharged from the device through the rotation of the spiral plate 18. When there is a lot of raw material scattered at the bottom of the inner cavity of the connecting frame 14 and the discharge speed is slow, the power motor 19 is started, causing the rotating rod 20 to drive the gear 21 to rotate. This causes the two toothed plates 22 to drive the two connecting plates 23 to move horizontally in opposite directions under the limiting action of the limiting plate 26. Finally, the two pusher plates 25 move horizontally towards each other under the limiting action of the connecting frame 14, thus pushing the raw materials scattered at the bottom of the inner cavity of the connecting frame 14 into the discharge box 15. This achieves the purpose of adjusting the discharge rate and prevents the raw materials from falling directly into the inner cavity of the discharge box 15 after passing through the feeding plate 13, which would result in an excessive discharge volume and cause discharge difficulties.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
