Description

Technical Field

[0001] This invention belongs to the technical field of calcium carbonate production equipment, specifically relating to a breathable membrane functional calcium carbonate production device and its production process. Background Technology

[0002] Breathable membranes are made by blending approximately 50% special calcium carbonate into a PE or PP carrier, extruding the mixture into a film, and then stretching it to a certain ratio. They are widely used in pharmaceutical and hygiene product packaging, food packaging, and daily necessities. The production of breathable membranes involves two key factors: calcium carbonate and stretching. The performance indicators of calcium carbonate directly affect the processability (such as coking time, extrusion stability, fabrication of thin films, and pinhole defects) and physical properties (such as air permeability, water pressure resistance, thermal stability, and mechanical properties) of the breathable membrane.

[0003] In the production process of functional calcium carbonate polymer masterbatch, calcium carbonate powder needs to be uniformly mixed with polyolefin matrix, plasticizer, stabilizer and other additives, and then extruded and granulated under heat and pressure to produce functional calcium carbonate polymer new material for breathable membranes; the mixing of calcium carbonate powder and additives needs to be carried out by appropriate production equipment.

[0004] However, existing mixing devices, when in use, mostly consist of simple stirring paddles that mix calcium carbonate powder under the rotation of a stirring shaft. This means that the stirring paddles cannot effectively perform multi-functional mixing of calcium carbonate powder and additives, resulting in low mixing uniformity of calcium carbonate powder and additives, which affects the overall performance of calcium carbonate powder.

[0012] Furthermore, a pair of upper cranks coaxially arranged with the lower crank are rotatably connected to the drive box, a synchronous crank is rotatably connected to the lower crank, and the other end of the synchronous crank is rotatably connected to the upper crank; an upper traction rod is rotatably connected to each pair of upper cranks, an upper traction frame is rotatably connected to the upper traction rod, an upper traction cylinder is fixed to the upper traction frame, and a spline cylinder is rotatably connected to the upper traction cylinder.

[0013] Furthermore, multiple upper fixed frames are fixedly connected to the splined cylinder, and the upper fixed frames and lower sliding frames are staggered. The upper stirring rod is rotatably connected to the upper fixed frame. A middle fixed frame is provided between adjacent upper fixed frames and lower sliding frames and is fixedly connected to the splined shaft. The splined cylinder is provided with a slide rail corresponding to the middle fixed frame. An upper driving rod that is rotatably connected to the upper stirring rod is rotatably connected to the middle fixed frame. A lower driving rod that is rotatably connected to the lower stirring rod is also rotatably connected to the middle fixed frame. The splined cylinder is provided with spline strips, and the lower sliding frame is provided with spline grooves that mate with the spline strips.

[0014] Furthermore, a mixing motor is fixedly connected to the mixing tank, and the output end of the mixing motor is fixedly connected to the spline shaft; a support rod is fixedly connected to the spline shaft, and the support rod is rotatably connected to the drive box.

[0015] A process for producing breathable membrane functional calcium carbonate includes the following steps:

[0016] S1. Open the valve on the feeding pipe and add calcium carbonate powder, polyolefin matrix, plasticizer, stabilizer and other additives into the mixing tank through the feeding pipe;

[0017] S2. Start the mixing motor. The mixing motor drives the splined cylinder to rotate through the splined shaft. The splined cylinder drives the lower sliding frame to rotate through the splined strip and splined groove. The splined cylinder drives the upper stirring rod to move. The lower sliding frame drives the lower stirring rod to move. The upper and lower stirring rods work together to stir the calcium carbonate powder and additives.

[0018] S3. Start the drive motor. The drive motor drives the rotating crank to rotate through the worm gear, worm wheel, input bevel gear set, and output bevel gear set. The rotating crank drives the mixing barrel to rotate along the support frame through the connecting rod.

[0019] S4. At the same time, the worm gear drives the lower sliding frame to slide along the splined cylinder through the lower crank, lower traction rod, lower traction cylinder, and connecting cylinder. The lower sliding frame drives the lower stirring rod to rise and fall. Under the action of the lower drive rod, the lower stirring rod rotates along the lower sliding frame. The lower crank drives the upper crank to rotate through the synchronous crank. The upper crank drives the upper stirring rod to rise and fall through the upper traction rod, upper traction cylinder, and splined cylinder. Under the action of the upper drive rod, the upper stirring rod rotates along the upper fixed frame.

[0020] S5. After the calcium carbonate powder and additives are mixed, open the valve on the discharge pipe to allow the calcium carbonate to flow out through the discharge pipe.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In use, this invention, through the arrangement of a drive structure, a flipping structure, a spline shaft, a spline cylinder, a lower sliding frame, an upper stirring rod, a lower stirring rod, an upper drive rod, and a lower drive rod, causes the spline shaft to rotate, which in turn drives the spline cylinder to rotate. The spline cylinder then drives the lower sliding frame to rotate, which in turn drives the upper stirring rod to move. The lower sliding frame then drives the lower stirring rod to move. The upper and lower stirring rods work together to stir the calcium carbonate powder and additives. In addition, the drive structure drives the spline cylinder and the lower sliding frame to move synchronously in opposite directions. The upper stirring rod rotates along the spline shaft as the spline cylinder slides, and the lower stirring rod rotates along the spline cylinder as the lower sliding frame slides. This allows the upper and lower stirring rods to change the direction of stirring while moving up and down, effectively improving the uniformity of the mixing of calcium carbonate powder and additives.

[0023] 2. In use, the present invention, through the setting of worm gear, worm shaft, input bevel gear set, output bevel gear set, etc., enables the rotating crank to move synchronously with the upper and lower cranks. That is, when the mixing tank is rotated by the rotating crank and connecting rod, the upper and lower cranks drive the upper and lower stirring rods to change the stirring direction while rising and falling through the upper and lower traction rods, so that the upper stirring rod is consistent with the flow direction of calcium carbonate powder in the mixing tank, which can effectively improve the uniformity of mixing of calcium carbonate powder and additives.

[0035] In use, calcium carbonate powder, polyolefin matrix, plasticizer, stabilizer and other additives are added into mixing tank 6; the spline shaft 16 is rotated, the spline shaft 16 drives the spline cylinder 17 to rotate, the spline cylinder 17 drives the lower sliding frame 36 to rotate, the spline cylinder 17 drives the upper stirring rod 11 to move, and the lower sliding frame 36 drives the lower stirring rod 14 to move. The upper stirring rod 11 and the lower stirring rod 14 work together to stir the calcium carbonate powder and additives.

[0036] At the same time, the drive structure is activated, causing the splined cylinder 17 and the lower sliding frame 36 to move synchronously in opposite directions. The upper stirring rod 11 rotates as the splined cylinder 17 slides along the splined shaft 16, and the lower stirring rod 14 rotates as the lower sliding frame 36 slides along the splined cylinder 17, so that the upper stirring rod 11 and the lower stirring rod 14 change the direction of stirring while moving up and down. In addition, the drive structure synchronously drives the mixing tank 6 to swing back and forth along the support frame to improve the uniformity of mixing of calcium carbonate powder and additives in the mixing tank 6.

[0037] Furthermore, the support frame includes a base plate 1, with side supports 2 fixedly connected to both sides of the base plate 1, and a reinforcing frame 8 fixedly connected to the mixing tank 6 and rotatably connected to the side supports 2; a rear support 5 is also fixedly connected to the base plate 1, and a flipping structure is disposed on the rear support 5, with each pair of side supports 2 fixedly connected to the rear support 5; the base plate 1, side supports 2, and rear support 5 cooperate to form the structure of the support frame, with the side supports 2 supporting the mixing tank 6 and the rear support 5 supporting the flipping structure, thereby improving the stability of this application.

[0038] Furthermore, the mixing tank 6 is provided with a feeding pipe 7 and a discharge pipe 9 corresponding to the feeding pipe 7. Both the feeding pipe 7 and the discharge pipe 9 are provided with valves. Calcium carbonate powder, polyolefin matrix, plasticizer, stabilizer and other additives are added into the mixing tank 6 through the feeding pipe 7. After the calcium carbonate powder and additives are stirred, they flow out through the discharge pipe 9.

[0039] Furthermore, the drive structure includes a drive housing, on which a drive motor 21 is fixedly connected; the output end of the drive motor 21 is connected to a worm gear 22, and a worm wheel 23 meshes with the worm gear 22, the worm wheel 23 being connected to the tilting structure; when the drive structure is in use, the drive motor 21 is started, and the drive motor 21 drives the worm wheel 23 to rotate through the worm gear 22, the worm wheel 23 driving the tilting structure to move; through the arrangement of the worm gear 22 and the worm wheel 23, the tilting structure, as well as the lower crank 26 and the upper crank 31, are self-locked, improving the stability of this application.

[0041] When the flipping structure is in use, the worm gear 23 rotates, driving the input bevel gear set 35 to rotate. The input bevel gear set 35 drives the output bevel gear set 19 to move through the universal coupling 20. The output bevel gear set 19 drives the flipping crank 4 to rotate, and the flipping crank 4 drives the mixing barrel 6 to flip along the side support 2 through the connecting rod 3. In addition, during the flipping process of the mixing barrel 6, the universal coupling 20 moves with the movement of the flipping barrel.

[0042] Furthermore, such as Figure 4 As shown, the worm gear 23 is coaxially fixed to the driving wheel 24, and the driving wheel 24 is meshed with the driven wheel 25; both the driving wheel 24 and the driven wheel 25 are coaxially fixed to the lower crank 26, and the lower traction rod 28 is rotatably connected to the lower crank 26; the mixing tank 6 is slidably connected to the lower traction cylinder 29, and the lower traction frame is fixed to the lower traction cylinder 29; both of the lower traction rods 28 are rotatably connected to the lower traction frame; the lower traction cylinder 29 is rotatably connected to the connecting cylinder 29, and the synchronizing rod 18 is fixed to the connecting cylinder 10; multiple lower sliding frames 36 are fixed to the synchronizing rod 18.

[0043] When the worm gear 23 rotates, it drives the driving wheel 24 to rotate, and the driving wheel 24 drives the driven wheel 25 to rotate. The driving wheel 24 and the driven wheel 25 synchronously drive the lower crank 26 to rotate. The lower crank 26 drives the lower traction cylinder 29 to slide along the mixing tank 6 through the lower traction rod 28 and the lower traction frame. The lower traction cylinder 29 drives the synchronizing rod 18 to move up and down through the connecting cylinder 10. The synchronizing rod 18 drives the lower sliding frame 36 to move up and down.

[0044] Furthermore, a pair of upper cranks 31 coaxially arranged with the lower crank 26 are rotatably connected to the drive box. A synchronous crank 27 is rotatably connected to the lower crank 26, and the other end of the synchronous crank 27 is rotatably connected to the upper crank 31. A pointer 30 is coaxially fixed to one of the upper cranks 31. The pointer 30 facilitates the observation of the rotation state of the upper crank 31, improving the convenience of this application.

An upper traction cylinder 33 is fixed to the upper traction frame. The spline cylinder 17 is rotatably connected to the upper traction cylinder 33. When the lower crank 26 rotates, the lower crank 26 drives the upper crank 31 to rotate along the drive box through the synchronous crank 27. The upper crank 31 drives the upper traction cylinder 33 to move up and down through the upper traction rod 32 and the upper traction frame. The upper traction cylinder 33 drives the spline cylinder 17 to move up and down. The spline cylinder 17 drives the upper stirring rod 11 to move up and down.

[0045] Furthermore, such as Figure 6-9As shown, multiple upper fixed frames 38 are fixedly connected to the splined cylinder 17, and the upper fixed frames 38 and lower sliding frames 36 are staggered. The upper stirring rod 11 is rotatably connected to the upper fixed frames 38. A middle fixed frame 37 is provided between adjacent upper fixed frames 38 and lower sliding frames 36 and is fixedly connected to the splined shaft 16. The splined cylinder 17 is provided with a slide rail 40 corresponding to the middle fixed frame 37. An upper driving rod 12 rotatably connected to the upper stirring rod 11 is rotatably connected to the middle fixed frame 37, and a lower driving rod 13 rotatably connected to the lower stirring rod 14 is also rotatably connected to the middle fixed frame 37.

In addition, when the splined cylinder 17 and the lower sliding frame 36 move, under the action of the upper driving rod 12 and the lower driving rod 13 on the middle fixed frame 37, the upper stirring rod 11 rotates along the upper fixed frame 38, and the lower stirring rod 14 rotates along the lower sliding frame 36.

[0048] A process for producing breathable membrane functional calcium carbonate includes the following steps:

[0049] S1. Open the valve on the feeding pipe 7 and add calcium carbonate powder, polyolefin matrix, plasticizer, stabilizer and other additives into the mixing tank 6 through the feeding pipe 7;

[0050] S2. Start the mixing motor 15. The mixing motor 15 drives the spline shaft 16 to rotate. The spline shaft 16 drives the spline cylinder 17 to rotate. The spline cylinder 17 drives the lower sliding frame 36 to rotate through the spline bar 39 and spline groove. The spline cylinder 17 drives the upper stirring rod 11 to move.

[0051] S3. Start drive motor 21. Drive motor 21 drives worm wheel 23 to rotate through worm 22. Worm wheel 23 drives input bevel gear set 35 to rotate. Input bevel gear set 35 drives output bevel gear set 19 to move through universal coupling 20. Output bevel gear set 19 drives tilting crank 4 to rotate. Tilting crank 4 drives mixing barrel 6 to tilt along side support 2 through connecting rod 3.

[0052] S4. Simultaneously, the worm gear 23 drives the driving wheel 24 to rotate, and the driving wheel 24 drives the driven wheel 25 to rotate. The driving wheel 24 and the driven wheel 25 synchronously drive the lower crank 26 to rotate. The lower crank 26 drives the lower traction cylinder 29 to slide along the mixing tank 6 through the lower traction rod 28 and the lower traction frame. The lower traction cylinder 29 drives the synchronizing rod 18 to move up and down through the connecting cylinder 10. The synchronizing rod 18 drives the lower sliding frame 36 to move up and down. In addition, the lower crank 26 drives the upper crank 31 to rotate along the drive box through the synchronizing crank 27. The upper crank 31... The upper traction rod 32 and the upper traction frame drive the upper traction cylinder 33 to move up and down, which in turn drives the splined cylinder 17 to move up and down, which in turn drives the upper stirring rod 11 to move up and down. Under the action of the upper drive rod 12 and the lower drive rod 13 on the middle fixed frame 37, the upper stirring rod 11 rotates along the upper fixed frame 38, and the lower stirring rod 14 rotates along the lower sliding frame 36. This changes the stirring direction of the upper stirring rod 11 and the lower stirring rod 14 while they are moving up and down, which can effectively improve the uniformity of the mixing of calcium carbonate powder and additives.

[0053] S5. After the calcium carbonate powder and additives are mixed, open the valve on the discharge pipe 9 to allow the calcium carbonate to flow out through the discharge pipe 9.

The splined cylinder (17) drives the lower sliding frame (36) to rotate through the splined strip (39) and splined groove. The splined cylinder (17) drives the upper stirring rod (11) to move. The lower sliding frame (36) drives the lower stirring rod (14) to move. The upper stirring rod (11) and the lower stirring rod (14) work together to stir the calcium carbonate powder and additives. S3. Start the drive motor (21). The drive motor (21) drives the rotating crank (4) to rotate through the worm (22), worm wheel (23), input bevel gear set (35), and output bevel gear set (19). The rotating crank (4) drives the mixing barrel (6) to rotate along the support frame through the connecting rod (3). S4. At the same time, the worm gear (23) drives the lower sliding frame (36) to slide along the splined cylinder (17) through the lower crank (26), lower traction rod (28), lower traction cylinder (29), and connecting cylinder (10). The lower sliding frame (36) drives the lower stirring rod (14) to rise and fall. Under the action of the lower drive rod (13), the lower stirring rod (14) rotates along the lower sliding frame (36). The lower crank (26) drives the upper crank (31) to rotate through the synchronous crank (27). The upper crank (31) drives the upper stirring rod (11) to rise and fall through the upper traction rod (32), upper traction cylinder (33), and splined cylinder (17). Under the action of the upper drive rod (12), the upper stirring rod (11) rotates along the upper fixed frame (38). S5. After the calcium carbonate powder and additives are mixed, open the valve on the discharge pipe (9) to allow the calcium carbonate to flow out through the discharge pipe (9).
