Abstract
The utility model discloses a press wheel assembly, and relates to the technical field of press wheels. The press wheel assembly comprises a connecting rod, wherein the connecting rod is provided with a groove; a rolling wheel is sleeved on the groove; two sides of the groove are provided with inwards sunk hemispherical grooves; steel balls are arranged in the hemispherical grooves; and the steel balls are propped against the sides of the rolling wheel. The press wheel assembly disclosed by the utility model is simple in structure and reasonable in design; the steel balls are utilized to be propped against the two sides of the rolling wheel, on the promise of not influencing the rolling of the rolling wheel, the steel balls can play a role in fixing the rolling wheel, thus the rolling wheel is prevented from rolling back and forth in the groove so as not to be positioned accurately, and a pressed object does not move leftwards and rightwards; the press wheel assembly is simple, practical and good in effect.
Description
Technical field:
The utility model relates to pinch roller technical field, is specifically related to a kind of pinch roller assembly.
Background technology:
Pinch roller mainly plays the function that transmit extruding location, existing pinch roller is mainly comprised of pipe link and roller, roller rotates on pipe link, but for guaranteeing the rotation alerting ability of roller, roller and pipe link have a large amount of spaces, roller moves around may appear at gap when rolling in, causes being transmitted thing and occurs sway, and situation is accurately transmitted not in location.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, and a kind of compact conformation is provided, and roller support is accurately transmitted in pinch roller location.
Technical problem to be solved in the utility model realizes by the following technical solutions.
, comprising pipe link, pipe link is provided with groove, and on groove, cover has roller, it is characterized in that: described groove two sides are provided with the hemisphere groove caving inward, and in hemisphere groove, are placed with steel ball, and steel ball withstands on roller side.
Described hemisphere groove is around groove side surface one week, and the hemisphere groove on groove communicates with hemisphere groove, forms annular hemisphere groove, and steel ball can be moving at annular hemisphere trough roller, more flexible, thereby it is more flexible that roller is rotated.
The utility model is simple in structure, reasonable in design, utilizes steel ball to withstand the both sides of roller, do not affect the effect of playing fixed idler whell position when roller rolls, avoiding the roller roller location that rolling causes back and forth in groove inaccurate, pressed thing sway, simple and practical, effective.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: pipe link; 2: groove; 3: roller; 4: hemisphere groove; 5: steel ball.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of pinch roller assembly as shown in Figure 1, comprise pipe link 1, pipe link 1 is provided with groove 2, on groove 2, cover has roller 3, and groove 2 two sides are provided with the hemisphere groove 4 caving inward, and are placed with steel ball 5 in hemisphere groove 4, steel ball 5 withstands on roller 3 sides, wherein hemisphere groove 4 is around groove 2 side one week, and the hemisphere groove 4 on groove communicates with hemisphere groove 4, forms annular hemisphere groove.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
