AI Technical Summary
In existing plastic granulation equipment, the guide rollers on the cooling tank are fixed and cannot be adjusted according to demand, which affects the flexibility of the strip travel route. In addition, when adjusting the guide rollers, the staff need to hold the strips by hand to affect efficiency and increase labor intensity.
A guide roller mechanism movably connected to the cooling groove is designed, and the flexible position adjustment and fixation of the guide roller is achieved through the rotating shaft, connecting piece, angle iron and hinged top rod, so as to facilitate the preset of suitable guidance routes.
It realizes flexible adjustment of the guide roller position, improves the controllability of the pull-up route, reduces the labor intensity of the staff, and simplifies the installation and disassembly of the guide roller.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic granulation equipment, and relates to a guide roller mechanism on a plastic granulation cooling tank. Background Art
[0002] In the process of plastic granulation production, waste plastics need to be made into strip-shaped semi-finished products, and then introduced into a cooling tank, where they are quickly cooled and solidified by water cooling. In order to keep the drawn strip submerged in water in the cooling tank all the time and smoothly and continuously move forward under the traction of the subsequent granulator, several guide rollers are generally arranged in the cooling tank, so that the drawn strip can pass through, be pressed down, or be supported between multiple guide rollers, thereby guiding the moving route of the drawn strip.
[0003] In the prior art, the positions of most guide rollers on the cooling tank are fixed. In this way, during actual production, workers cannot adjust their positions according to needs, and thus cannot adjust the moving route of the drawn strip. More importantly, at the beginning of production, when workers pull the drawn strip, they need to hold the drawn strip and pass under the guide roller. This not only affects the efficiency, but also increases the labor intensity because their hands are repeatedly inserted into the water, which is not conducive to their physical and mental health. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a guide roller mechanism on a plastic granulation cooling tank for the above problems existing in the prior art, which is movably connected to the cooling tank, so as to facilitate presetting a suitable guiding route for the plastic drawn strip.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A guide roller mechanism on a plastic granulation cooling tank includes a cooling tank body and several guide roller bodies located in the cooling tank. It is characterized in that a rotating shaft is rotatably connected in the guide roller body, and connecting pieces are fixed at both ends of the rotating shaft through nuts respectively. The two connecting pieces and the guide roller body together form a "U"-shaped mechanism. Angle irons are horizontally welded at the tops of the connecting pieces. When this guide roller mechanism is located in the cooling tank, the two angle irons can just straddle the inner top of the cooling tank body, and the length of each angle iron is at least half of the length of the connecting piece. Two ejector rods are arranged between the two angle irons. One end of each ejector rod is hinged to the corresponding angle iron, and the other ends of the two ejector rods are also hinged together. A plurality of guide grooves are formed on the outer peripheral surface of the guide roller body.
[0006] The advantages of the utility model are as follows:
[0007] 1. This guide roller structure is movably connected to the cooling tank, so we can adjust its position at any time according to needs, and thus guide and preset a suitable moving route for the drawn strip.
[0008] 2. In this guide roller structure, two hinged ejector rods are used to push two angle irons outwards, so that the whole structure is stuck in the cooling groove, thereby realizing the fixation of the guide roller mechanism, making its installation and disassembly extremely convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 is a three-dimensional structure schematic diagram of the guide roller mechanism.
[0010] Figure 2 is a side view structure schematic diagram of the guide roller mechanism.
[0011] Figure 3 is an application scenario schematic diagram of the guide roller mechanism.
[0012] In the figure, 1 is the cooling groove body; 2 is the guide roller body; 3 is the rotating shaft; 4 is the connecting piece; 5 is the angle iron; 6 is the ejector rod. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0014] As Figure 1 and Figure 2 shown, a guide roller mechanism on a plastic granulation cooling groove includes a cooling groove body 1 and a plurality of guide roller bodies 2 located in the cooling groove. A rotating shaft 3 is rotatably connected inside the guide roller body 2. Connecting pieces 4 are fixed to both ends of the rotating shaft 3 by nuts respectively. The two connecting pieces 4 and the guide roller body 2 together form a "U"-shaped structure; Angle irons 5 are horizontally welded to the top ends of each connecting piece 4. When the guide roller mechanism is located in the cooling groove, the two angle irons 5 can just straddle the inner top end of the cooling groove body 1, and the length of each angle iron 5 is at least half of the length of the connecting piece 4; There are two ejector rods 6 between the two angle irons 5. One end of each ejector rod 6 is hinged to the corresponding angle iron 5, and the other ends of the two ejector rods 6 are also hinged together; A plurality of guide grooves are provided on the outer peripheral surface of the guide roller body 2.
[0015] The working principle is as Figure 3As shown: During the actual production process, when the extruded strips from the extruder travel in the cooling tank, their length is relatively long. Therefore, in some places, the guide roller body 2 is needed to support them to prevent them from touching the bottom, while in some other places, the guide roller body 2 is needed to press them down to submerge them. And this guide roller structure is movably connected to the cooling tank. Especially for the places where pressing down is needed, there is no need for workers to tow underwater. Instead, after the towing is completed, this guide roller mechanism can be placed so that the guide roller body 2 presses on the strip above, so that this place is submerged below the water surface. When the position is determined, this guide roller mechanism can be fixed in the cooling tank, thereby avoiding the situation of its movement or tipping due to the pulling of the strip. Due to the certain elasticity of the two connecting pieces 4, the fixing and disassembly of this guide roller mechanism are extremely convenient. When fixing, we only need to press down the hinge parts of the two ejector rods 6, then the two ejector rods 6 push the two angle irons 5 outwards, so that this guide roller structure is stuck in the cooling tank; while when disassembling, we only need to pull up the hinge parts of the two ejector rods 6.
[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
