[0002] The current water jet loom mainly has a fixed rear beam that cannot swing. When replacing the warp beam, since the warp beam is long and located at the rear of the loom, the operating space is relatively small. Therefore, it becomes quite difficult to operate behind the machine, which not only restricts the operation but also takes more time. This design limitation makes a series of inconveniences in daily loom maintenance and adjustment, which may affect work efficiency and convenience of operation.

The first is a support plate, which is tightly connected to the rear beam seat. The rear beam seat is connected to the movable bearing seat by a hinge, and the rear beam shaft is installed in the movable bearing seat. The rear beam shaft is connected to the swinging rear beam on the swinging bearing seat of the rear beam, and the rear beam support is provided with a slideway for guiding the movable bearing seat. Finally, the movable bearing seat is fastened to the rear beam support by fasteners.

[0004] However, during the actual use of the above-mentioned equipment, the heating phenomenon caused by the bearings in the rear beam swing bearing seat due to long-term rotation and friction will have an adverse effect on the bearings in the rear beam swing bearing seat. The heating will cause premature wear of machine parts, reduce the working efficiency of the bearings, and even cause damage to the bearings, affecting the normal operation of the entire water jet loom. In view of this, we propose a movable back beam. Utility Model Content

[0027] In one embodiment of the utility model, a through hole is provided on the side wall of the connecting member 5, and air flow can flow through the through hole to avoid heat accumulation. A fan blade 8 is fixedly connected to the side wall of the rotating shaft 4, and one end of the fan blade 8 close to the rear beam swing bearing seat 2 is fixedly connected to the magnetic member 14. A radiator 9 is fixedly connected to the side of the outer ring close to the connecting member 5. An annular pipe 11 is provided in the radiator 9, and a steel ball 15 is arranged in the annular pipe 11. A slide groove 13 is provided on the side of the radiator 9 close to the fan blade 8. The slide groove 13 is arranged in an annular shape, and the slide groove 13 is movable with the magnetic member 14. The magnetic member 14 is magnetically connected to the steel ball 15 arranged in the radiator 9. A radiator 2 10 is fixedly connected to the side of the inner ring close to the connecting member 5. An annular pipe 11 is opened in the radiator 10, and a steel ball 15 is arranged in the annular pipe 11. The diameter of the steel ball 15 is smaller than the inner diameter of the annular pipe 11. The steel ball 15 disturbs and pushes the coolant arranged in the annular pipe 11 to improve the fluidity of the coolant. The inner wall of the radiator 19 is fixedly connected with a protrusion 12, and the outer wall of the radiator 10 is fixedly connected with a protrusion 12. The protrusion 12 arranged on the radiator 19 does not contact the protrusion 12 arranged on the radiator 10. A connecting piece 16 is fixedly connected to the side of the radiator 19 close to the fan blade 8, and a magnet 17 is fixedly connected to the bottom end surface of the connecting piece 16. The magnet 17 is magnetically linked to the steel ball 15 arranged in the radiator 10.

[0028] The swinging rear beam 6 rotates during operation. When the swinging rear beam 6 rotates, the rotating shaft 4 also rotates, thereby driving the inner ring of the bearing body 3 to rotate, thereby generating heat through friction. When the rotating shaft 4 rotates, it drives the fan blades 8 to rotate, thereby sucking air into the rear beam swinging bearing seat 2 through the air diffusion holes 7. The airflow passes through the gap between the inner ring and the outer ring, taking away the heat generated by the bearing body 3. At the same time, part of the heat generated by the outer ring is conducted to the radiator 1 9, and part of the heat generated by the inner ring is conducted to the radiator 2 10. Since the surfaces of the radiator 1 9 and the radiator 2 10 are provided with a raised portion 12, the heat dissipation between the radiator 1 9 and the radiator 2 10 is improved. The surface area of ​​the radiator 1 9 and the radiator 2 10 is increased, thereby improving the heat exchange between the radiator 1 9 and the airflow, and improving the heat dissipation effect of the heat dissipation component. When the fan blade 8 rotates, it drives the magnetic part 14 to rotate. Since the magnetic part 14 is magnetically connected with the steel ball 15 arranged in the radiator 1 9, it drives the steel ball 15 arranged in the annular pipe 11 in the radiator 1 9 to move, disturbing and pushing the coolant in the annular pipe 11, improving the fluidity of the coolant, and can bring out the heat of the outer ring more quickly. At the same time, the uniformity of the heat distribution of the outer ring is improved, avoiding the different degrees of thermal expansion and contraction of the material caused by uneven heat distribution, and improving the service life of the bearing body 3.

[0029] In addition, in order to further improve the heat dissipation effect of the heat dissipation component, a connecting plate 16 is fixedly connected to one side of the radiator 9 close to the fan blade 8, and a magnet 17 is fixedly connected to the bottom end face of the connecting plate 16. The magnet 17 is magnetically connected to the steel ball 15 arranged in the radiator 2 10. The rotation of the rotating shaft 4 drives the inner ring to rotate. When the inner ring rotates, due to the magnetic connection between the magnet 17 and the steel ball 15, the steel ball 15 will not be displaced, thereby realizing the turbulence and promotion of the coolant in the annular pipe 11, improving the fluidity of the coolant, and can bring out the heat of the inner ring more quickly. At the same time, the uniformity of the heat distribution of the inner ring is improved, avoiding the uneven degree of thermal expansion and contraction of the material caused by uneven heat distribution, and improving the working efficiency of the bearing body 3.

[0030] In the utility model, when the shaft 4 rotates, the fan blades 8 are driven to rotate, and then the air is sucked into the rear beam swing bearing seat 2 through the air diffusion holes 7. The airflow passes through the gap between the inner ring and the outer ring to take away the heat generated by the bearing body 3. When the fan blades 8 rotate, the magnetic member 14 is driven to rotate. Since the magnetic member 14 is magnetically connected with the steel ball 15 arranged in the radiator 9, the steel ball 15 is driven to move in the annular pipe 11 arranged in the radiator 9, the coolant in the annular pipe 11 is disturbed and pushed, and the fluidity of the coolant is improved. The heat of the outer ring can be brought out more quickly, and the uniformity of heat distribution in the outer ring can be improved, thereby avoiding different degrees of thermal expansion and contraction of the material due to uneven heat distribution. Furthermore, since the magnet 17 is magnetically connected to the steel ball 15, the steel ball 15 will not be displaced, thereby disturbing and pushing the coolant in the annular pipe 11, improving the fluidity of the coolant, and bringing out the heat of the inner ring more quickly. At the same time, the uniformity of heat distribution in the inner ring can be improved, thereby avoiding different degrees of thermal expansion and contraction of the material due to uneven heat distribution, and improving the working efficiency of the bearing body 3.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
