Description
Technical Field
The utility model belongs to the technical field of biaxial stretching polystyrene sheet production, especially, relate to a sheet is indulged and is drawn steel roller rotary joint installation concentricity structure.
Background
In the production process of BOPS sheets (biaxially oriented polystyrene sheets), longitudinal drawing of a BOPS biaxial stretching production line is realized by the speed difference of each steel roller. According to the process requirement, hot water needs to be introduced into the steel roller, and the temperature of the surface of the steel roller is controlled by changing the temperature of the hot water according to the process requirement. Because the steel roller is rotatory, so need connect the water route at steel roller both ends with rotary joint. Because there is the defect in the end connection design of the water pipe terminal surface of steel roller terminal surface and rotary joint pipeline, cause the decentraction of both ends connection. When the device runs, one side of the rotary joint shakes seriously. The mechanical seal of the rotary joint is easy to leak water, and the metal hose flexibly connected with the rotary joint is also fatigue-damaged and frequently leaks water due to shaking. As shown in fig. 1, a first connecting flange 2 is connected with a steel rod 1 through a first taper sleeve 3, a metal hose 7 is connected with a rotary joint 6, a second connecting flange 5 is connected with the rotary joint 6 through a second taper sleeve 4, the first connecting flange 2 and the second connecting flange 5 are respectively and fixedly connected with two ends of a connecting seat 10, the steel rod 1 is hermetically connected with the connecting seat 10 through a first gasket 8, and the rotary joint 6 is hermetically connected with the connecting seat 10 through a second gasket 9; in the drawing, the connecting seat is used as transition connection, the shaft end pipelines on two sides are provided with the connecting flange, the connecting flange is supported by two half taper sleeves embedded in the annular groove of the shaft end pipeline as stress, and the inner hole of the connecting flange is in corresponding taper fit with the taper sleeves. The connecting seat and the end surfaces of the two side shaft end pipelines are tightly attached and fastened by bolts, and are sealed by gaskets at the attaching parts, and after the connecting seat is installed, although the attaching sealing parts do not leak water when the connecting seat and the two side shaft end pipelines are in clearance fit, the concentricity of the rotary joint and the steel roller is poor, so that the rotary joint is greatly rocked.
SUMMERY OF THE UTILITY MODEL
An object of the embodiment of the utility model is to provide a sheet is indulged and is drawn steel roller rotary joint installation concentricity structure can improve rotary joint rotary pipeline and steel roller concentricity, reduces and rocks the degree.
The embodiment of the utility model provides a realize like this:
the utility model provides a sheet is indulged and is drawn steel roller rotary joint installation concentricity structure, includes steel rod, first flange, first taper sleeve, rotary joint, metal collapsible tube, first gasket, and first flange is connected with the steel rod through first taper sleeve, and metal collapsible tube is connected with rotary joint, still includes: the steel rod is connected with the left side of the connector in a sealing mode through a first gasket, the steel rod is in interference fit with an inner hole in the left side of the connector, the inner sealing thread is located in the center of the right side of the connector, the outer sealing thread is located on the rotary connector, the inner sealing thread is matched with the outer sealing thread, and the rotary connector is connected with the connector in a sealing mode through the inner sealing thread and the outer sealing thread.
The embodiment of the utility model provides a replace the sealed mode of relying on pipeline tip gasket through adopting thread seal, thread seal has improved the concentricity simultaneously, improves swivel joint rotary pipe and steel roller concentricity problem, has greatly reduced swivel joint and metal collapsible tube's fault rate after improving. The concentric problem of rotary joint rotation pipeline and steel roller is improved, just so can reduce and rock the water route problem that causes.
Drawings
FIG. 1 is a structure diagram of a rotary joint of a sheet longitudinal drawing steel roller in the prior art;
fig. 2 is the utility model discloses well sheet indulges and draws steel roller rotary joint installation concentricity structure.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description is given to specific implementations of the present invention with reference to specific embodiments:
as shown in fig. 2, a sheet is indulged and is drawn steel roller rotary joint installation concentricity structure, includes steel rod 1, first flange 2, first taper sleeve 3, rotary joint 6, metal collapsible tube 7, first gasket 8, and first flange is connected with the steel rod through first taper sleeve, and metal collapsible tube is connected with rotary joint, still includes: the connector 11, the internal seal screw thread 12 and the external seal screw thread 13, the steel rod is through first gasket and connector left side sealing connection, steel rod and connector left side hole interference fit, and the internal seal screw thread is located right side central point in the connector and puts, and the external seal screw thread is located the rotary joint, and internal seal screw thread and external seal screw thread phase-match, rotary joint and connector pass through internal seal screw thread and external seal screw thread sealing connection.
The utility model discloses an in the embodiment, steel roller end pipeline and the being connected of rotary joint axle head pipeline. The utility model discloses in, deepen the cooperation degree of depth of connecting seat and steel roller side and adopt little excessive cooperation, guarantee that connecting seat hole steel roller is concentric. The connecting seat is sealed with one side of the rotary joint in a threaded fit manner, so that after the rotary joint and the steel roller are installed, the rotary joint and the steel roller can have good concentricity, and the rotary joint cannot shake during operation. The maintenance and replacement of the rotary joint at ordinary times are more convenient than the prior art.
The embodiment of the utility model provides a replace the sealed mode of relying on pipeline tip gasket through adopting thread seal, thread seal has improved the concentricity simultaneously, improves swivel joint rotary pipe and steel roller concentricity problem, has greatly reduced swivel joint and metal collapsible tube's fault rate after improving. The concentric problem of rotary joint rotation pipeline and steel roller is improved, just so can reduce and rock the water route problem that causes.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
