Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing mills, in particular to an open mixing mill for rubber processing. Background Art

[0002] The rubber mixing mill is a type of mixing mill used for plasticizing rubber. It is an early type of mixing plastic equipment used by plastic product manufacturers. On the calender production line, the mixing mill is before the calender and after the mixer. Its function is to mix and plasticize the evenly mixed raw materials, and provide a relatively evenly mixed molten material for the calender to form plastic products.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:

[0004] (1) In order to ensure that the plasticating of the open mixing mill is more uniform, the staff needs to continuously make triangle bags to turn the rubber during the plasticating process, which not only requires a large amount of manpower but also consumes a lot of physical strength;

[0005] (2) When cutting the rubber, manpower is required. People need to hold the cutter manually to cut it, which not only poses a great safety hazard, but also has a high labor cost. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides an open mixing mill for rubber processing, which has the function of folding up both sides of the rubber roll and folding them together before re-feeding them into the pressure roller for repeated plasticizing, and continuously adjusting the feeding position of the rubber after the centralized folding, so that the plasticizing of the rubber is more uniform, and there is no need for manual cutting with a knife, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical scheme: an open mixing mill for rubber processing, comprising a frame, an inner wall of the frame being rotatably connected to a pressure roller, a top end of the frame being fixedly connected to a mounting frame, a side surface of the mounting frame being provided with a slide groove, a card block being slidably engaged inside the slide groove, a side surface of the card block being rotatably connected to a sliding rod, a surface of the sliding rod being slidably sleeved with two movable sleeve blocks, a top end of the movable sleeve block being rotatably connected to a roller, a moving rod being provided on one side of the pressure roller, a sleeve being slidably sleeved on the surface of the moving rod, and a cutting wheel being rotatably connected to one end of the sleeve.

[0008] Preferably, the two movable sleeve blocks are fixedly connected via a second telescopic rod, and a locking bolt is threadedly connected to a side surface of the second telescopic rod.

[0009] Preferably, the inner wall of the installation frame is rotatably connected with a threaded column, and the clamping block is threadably sleeved on the surface of the threaded column.

[0010] Preferably, the bottom end of the movable sleeve block is fixedly connected to a telescopic rod 1, the bottom end of the telescopic rod 1 is fixedly connected to a mounting sleeve block, the interior of the mounting sleeve block is rotatably connected to an internal threaded barrel, the inner wall of the frame is rotatably connected to a threaded rod, and the internal threaded barrel is threadedly sleeved on the surface of the threaded rod.

[0011] Preferably, a second locking bolt is threadedly connected to the surface of the sleeve, and an end of the second locking bolt abuts against the surface of the moving rod.

[0012] Preferably, a second slide groove is provided on the surface of the frame, the slide rod is slidably engaged with the second slide groove, an electric push rod is fixedly connected to the side of the frame, and the end of the electric push rod is rotatably connected to the end of the moving rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By sliding the position of the movable sleeve block on the surface of the slide rod, the distance between the two movable sleeve blocks is adjusted, and when the position of the movable sleeve block is moving, the installation sleeve block will also move accordingly. During the movement of the installation sleeve block, the internal threaded cylinder will rotate inside the installation sleeve block. After the position of the movable sleeve block is confirmed, the locking bolt 1 can be tightened to fix the distance between the two movable sleeve blocks, so as to facilitate folding up the two sides of the rubber roll and folding them together and then re-sending them into the pressure roller for repeated plasticization according to different needs. At the same time, the threaded rod can be driven to rotate by the driving source, thereby driving the two installation sleeve blocks to move synchronously in the same direction, so that the feeding position of the rubber after the centralized folding can be continuously adjusted, so that the plasticization of the rubber is more uniform, which solves the problem that the existing rubber needs to be manually made into triangular bags for turning the rubber during refining, saving labor input and physical strength.

[0015] 2. By setting a moving rod, when the rubber on the surface of the pressure roller needs to be cut and collected, there are requirements for the width of the collection and cutting. At this time, the sliding sleeve is in the position of the surface of the moving rod. After the position of the cutting wheel is confirmed, the locking bolt 2 is tightened so that the end of the locking bolt 2 is tightly fitted with the surface of the moving rod, thereby effectively fixing the position of the cutting wheel. When the rubber on the surface of the pressure roller is cut, the electric push rod is started to drive the moving rod to move, so that the cutting wheel is fitted with the rubber on the surface of the pressure roller, thereby cutting the rubber. This effectively solves the problem of manual cutting with a knife when collecting the rubber, and the cutting width of the rubber can be customized. BRIEF DESCRIPTION OF THE DRAWINGS
