Description

Technical Field

[0001] The utility model relates to the technical field of floor production, in particular to mixing equipment for floor production. Background Art

[0002] The production process of PVC flooring includes mixing, mixing, kneading, cutting of fabrics and transparent materials, laying, oil pressing, laminating, tempering, curing, molding, chamfering / grooving, quality inspection and packaging.

[0003] The internal mixing equipment for PVC floor production is a kind of equipment used for internal mixing of PVC floor raw materials, which has been widely used in the field of internal mixing machinery. When the existing internal mixing equipment for PVC floor production is used, the internal mixing motor is first started, and then the relative movement of the rotor is controlled by the gearbox, and then the raw materials are put into the internal mixing chamber of the internal mixing box, and the internal mixing is carried out by the rotation of the rotor.

[0004] In the prior art, such as the patent document with application number CN201921746980.4 and titled "A Mixing Equipment for PVC Floor Production", when working, the air pump motor is first started, and the air is subjected to dust removal treatment in the dust removal box through the action of the air pump, and then the air is subjected to the action of the desiccant in the drying box to remove moisture from the air, and then the air is heated by the heating tube in the heating box, and then the mixing motor is started, and then the relative movement of the first mixing wheel and the second mixing wheel is controlled by the gearbox, and then the raw materials are placed in the mixing chamber of the mixing box, and the first mixing wheel and the second mixing wheel are engaged and rotated for mixing. The technical solution of this patent uses the action of the air pump to make the air pass through the dust removal treatment in the dust removal box so that dust-free air enters the mixing chamber, preventing the mixing raw materials from being mixed with dust and improving reliability; the air is subjected to the action of the desiccant in the drying box to remove moisture from the air, preventing the mixing raw materials from being mixed with water and improving reliability. However, the first process of PVC floor production is mixing, and mixing requires mixing PVC powder, plasticizer, stabilizer, lubricant and filler. In the initial stage of mixing, there is PVC powder in the mixture that is not fully mixed with plasticizer, stabilizer, lubricant and filler. Blowing air into the mixing chamber during mixing can easily cause the PVC powder to fly out of the loading and unloading ports, thereby generating dust.

[0005] The patent document with application number CN201920696481.2 and titled "An internal mixer for the production of fire-resistant PVC film light box cloth that is easy to unload" discloses an internal mixer that is convenient for extruding and stirring materials and convenient for unloading. During operation, materials are added to the inside of the cavity through the feed port, and the second motor drives the threaded rod to rotate, thereby driving the pulley below the threaded rod to rotate, and the belt drives the pulley and threaded rod in front to rotate at the same time, and the threaded rod is driven to slide upward by rotating the threaded rod clockwise, so as to facilitate the sealing of the lower end of the cavity, and the first motor drives the rotating rod to rotate, thereby driving the first gear to rotate, and the first gear is meshed and connected with the second gear, thereby driving the second gear to rotate, and then it is convenient to drive the rotating rod on the right to rotate at the same time, so that the first rotor and the second rotor rotate in opposite directions, and by rotating the first rotor and the second rotor in opposite directions, it is convenient to extrude and stir the materials inside the cavity. In the process of internal mixing of the mixture, when the temperature rises, the amount of plasticizer cannot be effectively absorbed when it is large, so it should be added in batches. In the solution of this patent, when plasticizer needs to be added during the mixing process, the upper push pin needs to be moved upward and then the plasticizer is added into the cavity, so it is not convenient to add the plasticizer in batches.

Specifically, the upper end of the lower telescopic rod 14 is fixedly connected to the lower top bolt 13, and the lower end of the lower telescopic rod 14 is fixedly connected to the bracket 2.

[0051] The upper end of the internal mixer 1 is fixedly connected with a standpipe 6, and an upper push bolt 12 is slidably sealed in the standpipe 6. A feed hopper 7 is fixedly connected to the standpipe 6. An upper push bolt 12 is slidably sealed in the standpipe 6, and an upper telescopic rod 8 is fixedly connected to the upper telescopic end of the upper telescopic rod 8 and fixedly connected to the upper push bolt 12.

[0052] The upper ejector pin 12 is provided with a feeding assembly.

[0053] The feeding assembly includes a blind hole 17 opened at the lower end of the upper push bolt 12, and an inner block 18 is slidably and sealably connected in the lower end of the blind hole 17, and the lower end of the inner block 18 is flush with the lower end of the upper push bolt 12. An inner tube 19 is fixed to the upper end of the inner block 18. A plurality of branch pipes 20 are fixedly connected to the lower end of the inner tube 19. The plurality of branch pipes 20 are evenly distributed according to the circumference of the axis of the inner tube 19. A piston ring 21 is fixed to the upper end of the inner tube 19, and the upper end of the inner tube 19 is flush with the upper end of the piston ring 21. The piston ring 21 is slidably and sealably connected to the blind hole 17. A stopper 22 is fixed in the blind hole 17 above the piston ring 21, and the lower end of the stopper 22 contacts the upper end of the inner tube 19. A plurality of cylinders 23 are fixed in the blind hole 17 above the piston ring 21, and the telescopic rods of the cylinders 23 are fixedly connected to the piston ring 21. A hose 9 is fixed to the upper end of the upper push bolt 12, and a channel 16 is opened in the upper push bolt 12. One end of the channel 16 is connected to the blind hole 17 above the piston ring 21, and the other end of the channel 16 is connected to the hose 9.
