Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing, in particular to a drawing roller used in the preparation of masterbatch. Background Art

[0002] Masterbatch is a mixture of resin and a large amount of pigment or dye with high concentration of color. Masterbatch, also known as color seed, is an aggregate made by uniformly loading an extraordinary amount of pigment or dye in resin. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve a colored resin or product with a designed pigment concentration. The production of masterbatch mainly includes weighing, mixing, grinding, dispersing, extrusion, drawing, pelletizing and packaging.

[0003] In the strip drawing process, rollers are used to transport and organize the masterbatch strips. In the existing technology, the operator places the rollers at the discharge port of the strip drawing, opens layers of ring sleeves on the outside of the rollers, and pulls the long strips drawn out by the masterbatch into the inside of the ring sleeves. This operation is convenient and fast, but in actual use, when it is necessary to produce long strips of masterbatch of different diameters in response to different market demands, the spacing between the ring sleeves is fixed and cannot be effectively adjusted according to the required diameter.

[0004] Therefore, it is particularly important to improve the existing drawing roller used in the preparation of masterbatch, design a new drawing roller used in the preparation of masterbatch to solve the above-mentioned technical defects, and improve the overall practicality of the drawing roller used in the preparation of masterbatch.

[0011] As a preferred solution of the utility model, a support rod is installed on the top of the load-bearing rod, and a connecting plate is installed on the top of the support rod.

[0012] As a preferred solution of the utility model, a mounting plate is installed on one side of the connecting plate away from the other, a stabilizing plate is installed inside the connecting plate, and the stabilizing plate is designed in an X-shaped structure.

[0013] As a preferred solution of the utility model, arc grooves are symmetrically opened inside the left and right ends of the rotating shaft, and the arc grooves are interconnected with the interior of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, the masterbatch strips are pulled into the interior of the annular sleeve, and the extension rod is rotated, so that the extension rod transmits the rotational force to the linkage shaft, thereby realizing the linkage shaft to rotate following the extension rod. At the same time, there are two groups of guide grooves, so that the slide rods can slide inside the guide grooves, thereby realizing the two groups of guide grooves to rotate in a spiral shape, so that the slide rods can move closer to each other inside the guide grooves, thereby completing the close proximity of the annular sleeves, so that the internal space of the annular sleeve is suitable for the masterbatch strips.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A drawing roller for preparing masterbatch comprises a rotating shaft 1, an annular sleeve 2 is installed on the outside of the rotating shaft 1, extension rods 3 are symmetrically installed at both ends of the rotating shaft 1, a linkage shaft 4 is installed between the extension rods 3 and inside the rotating shaft 1, a guide groove 5 is opened inside the linkage shaft 4, and the guide groove 5 is designed with a spiral structure.

[0024] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the surface of the rotating shaft 1 is symmetrically provided with slide grooves 6, and the inside of the annular sleeve 2 is symmetrically provided with slide rods 7, and the slide rods 7 extend to the inside of the guide grooves 5. The annular sleeve 2 is connected to the linkage shaft 4 through the slide rods 7. When the masterbatch is produced, the raw materials are placed inside the machine and extruded by heating to form a continuous strip. The operator pulls the strip into the inside of the annular sleeve 2. When the diameter of the masterbatch strip is thickened according to market demand, the extension rod 3 is rotated, and the extension rod 3 transmits the rotational force to the linkage shaft 4, so that the linkage shaft 4 rotates with the extension rod 3. At the same time, the guide grooves 5 are divided into two groups, so that the slide rods 7 can slide inside the guide grooves 5, so that the two groups of guide grooves 5 can rotate in a spiral shape, so that the slide rods 7 can move closer to each other inside the guide grooves 5, thereby completing the close proximity of the annular sleeves 2. Therefore, the internal space of the annular sleeve 2 is suitable for the masterbatch strips.

[0025] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the annular sleeve 2 is designed in a W-shaped structure, the annular sleeves 2 are distributed at equal intervals, and the surface of the annular sleeve 2 is coated with a non-stick material. The masterbatch strips are wrapped through the notches of the annular sleeve 2 to prevent the masterbatch strips from being dislocated when the strips are pulled. At the same time, the non-stick material and the masterbatch produce lubricity, which effectively prevents jamming during the pulling process, causing the strips to become wrinkled.

[0026] Furthermore, please see Figure 1In this embodiment, a sliding sleeve 8 is symmetrically installed at one end of the linkage shaft 4 that is away from the other end, a load-bearing rod 9 is installed on the outside of the sliding sleeve 8, the rotating shaft 1 is rotatably connected to the load-bearing rod 9 through the sliding sleeve 8, a support rod 10 is installed on the top of the load-bearing rod 9, and a connecting plate 11 is installed on the top of the support rod 10. A mounting plate 12 is installed on the side away from the connecting plate 11, and a stabilizing plate 13 is installed inside the connecting plate 11. The stabilizing plate 13 is designed in an X-shaped structure. By hanging the mounting plate 12 on the top of the masterbatch strip discharge chute, the X-shaped structure design of the stabilizing plate 13 can achieve greater stability between the two groups of mounting plates 12. At the same time, through the design of the support rod 10 and the load-bearing rod 9, there is enough space between the masterbatch strip and the annular sleeve 2. When the masterbatch strip passes through the annular sleeve 2, the friction force generated between the two will drive the rotating shaft 1 to rotate. Through the design of the sliding sleeve 8, the rotation of the rotating shaft 1 is smoother, preventing the rotating shaft 1 from getting stuck when the masterbatch strip moves at a uniform speed, resulting in wrinkles between the masterbatches.

[0027] For further information, see Figure 1 and Figure 2 In this embodiment, arc grooves 14 are symmetrically opened inside the left and right ends of the rotating shaft 1, and the arc grooves 14 are interconnected with the interior of the rotating shaft 1. Through the design of the arc grooves 14, they are linked with the interior of the rotating shaft 1, so that the interior of the rotating shaft 1 can circulate with the external air to prevent it from generating high temperature.

[0028] In this embodiment, the implementation scenario is specifically as follows: when the masterbatch is produced, the raw materials are placed inside the machine and extruded by heating to form a continuous strip. The mounting plate 12 is hung on the top of the masterbatch strip discharge trough and the X-shaped structure design of the stabilizing plate 13 is used to achieve greater stability between the two sets of mounting plates 12. At the same time, through the design of the support rod 10 and the load-bearing rod 9, sufficient space is provided between the masterbatch strip and the annular sleeve 2. The operator pulls the masterbatch strip into the interior of the annular sleeve 2 and rotates the extension rod 3. The extension rod 3 transmits the rotational force to the linkage shaft 4, so that the linkage shaft 4 rotates with the extension rod 3. At the same time, the guide groove 5 is divided into two groups, so that the slide bar 7 slides inside the guide groove 5, so that the two groups of guide grooves 5 rotate in a spiral shape, so that the slide bar 7 moves closer to each other inside the guide groove 5, thereby completing the close proximity of the annular sleeve 2. Therefore, the internal space of the annular sleeve 2 is adapted to the masterbatch strip.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
