Abstract

The utility model relates to an air cylinder type pony roll rack which is composed of a pony roll rack seat [12], a base [1], a swinging arm [4], an air cylinder [17] and a compression spring [2]. In the utility model, the bottom of the air cylinder [17] is hinged with a pin shaft [11] of the base [1]; a piston rod [15] is hinged with the swinging arm [4]. When the diameter of pony roll yarn is increased driving the swinging arm [4] to be upwards rotated round the pin shaft [14], an inner cavity of the air cylinder [17] forms vacuum negative pressure forming air damping which can preferably absorb dithering generated by a cantilever [6] when a main machine is in operation with better vibration damping effect; when a handle is poked for causing the pony roll rack to be reset, because of the apply work of air pressure to an air cylinder plunger, negative pressure likewise disappears, and thus torque for poking the handle is small.

Description

A kind of air-cylinder type bobbin cradle

Technical field

The creel parts one bobbin cradle parts that cheese on the utility model rotor spinning machine is shaped.

Background technology

The bobbin cradle parts of present domestic rotor spinning machine, as depicted in figs. 1 and 2, by bobbin stand [12], base [1], swing arm [4], damping arm [10], compression spring [2] is formed, the both sides of bobbin stand [12] are fixed with left and right sides cantilever [6], be fixed with bobbin dish [7] on the left and right sides cantilever [6], swing arm [4] one ends are hinged by bearing pin [14] and base [1], compression spring [2] is fixed between base [1] and the swing arm [4] by spring core [3], spring core [3] one ends are hinged by bearing pin [13] and swing arm [4], the other end is positioned at the radial direction through hole of the bearing pin [11] that is fixed on the base, the swing arm other end and bobbin stand [12] are connected, left and right sides damping arm [10] one ends are hinged by bearing pin [11] and base, the other end is connected with extension spring [5], the other end of extension spring [5] is fixed on the bearing pin [12], damping block [9] is housed in the swing arm [4], and damping arm [10] compresses damping block [9] by the tension force of extension spring [5], and the swing of swing arm can drive damping block and overcome the slide of the tension force of extension spring along damping arm inboard.The shortcoming of this structure is to increase and drive swing arm [4] around bearing pin [14] when upwards rotating when the cheese diameter, promptly compress spring [2] and go to solid line position by dotted line position among Fig. 1, because the precompression of compression spring is bigger, the pressure that the tension force of dependence extension spring [5] increases between damping arm [10] and the damping block [9] increases the vibration that damping is difficult to eliminate fully cantilever [6], and make bobbin stand [12] when resetting stirring handle [8], it is same because the tension force of extension spring makes that the moment of stirring handle is bigger, make operation inconvenient, and structure is complicated, processing capacity is big, the processing cost height.

Summary of the invention

To be solved in the utility model is big and the bigger and unhandy problem of moment because of stirring handle when resetting of above-mentioned bobbin cradle cantilever vibration.

The utility model is to solve like this, become by bobbin stand, base, swing arm, damping unit, compression spring set, the both sides of bobbin stand are fixed with left and right sides cantilever, be fixed with the bobbin dish on the cantilever of the left and right sides, swing arm one end and base [1] are hinged, and the compression spring is fixed between base and the swing arm by spring core, and the swing arm other end and bobbin stand are connected, damping unit is a cylinder, and its two ends are hinged on respectively in base and the swing arm.

When the cheese diameter increases and drives swing arm when bearing pin upwards rotates, the piston rod of cylinder is outwards stretched, cylinder inner cavity forms negative pressure of vacuum and forms air damping, can absorb the shake that left and right sides cantilever produces in the main frame running preferably, and effectiveness in vibration suppression is better.And when stirring handle the bobbin stand is resetted, same because air pressure is done work to cylinder piston, negative pressure disappears, the piston rod non-resistance that resets, thereby it is little to stir the moment of handle, and operation is easily, and is and simple and compact for structure, is convenient to processing.

The specific embodiment

By shown in Figure 3, the utility model bobbin cradle is by bobbin stand [12], base [1], swing arm [4], cylinder [17], compression spring [2] is formed, the both sides of bobbin stand [12] are fixed with left and right sides cantilever [6], left and right sides cantilever is fixed with the bobbin dish on [6], swing arm [4] one ends are hinged by bearing pin [14] and base [1], compression spring [2] is fixed between base [1] and the swing arm [4] by spring core [3], spring core [3] one ends are hinged by bearing pin [13] and swing arm [4], the other end is positioned at the radial direction through hole of the bearing pin [11] that is fixed on the base, the swing arm other end is connected by bolt [16] bobbin stand [12], cylinder [17] bottom is hinged on the bearing pin [11] of base [1], and piston rod [15] is hinged in the swing arm [4].Also can be the tailpiece of the piston rod hinge on the bearing pin of base, the cylinder end hinge is in swing arm.When the cheese diameter increases and drives swing arm [4] around bearing pin [14] when upwards rotating, the piston rod [15] of cylinder is outwards stretched, cylinder [17] inner chamber forms negative pressure of vacuum and forms air damping, can absorb the shake that cantilever [6] produces in the main frame running preferably, and effectiveness in vibration suppression is better.And when stirring handle bobbin cradle is resetted, same because air pressure is done work to cylinder piston, negative pressure disappears, piston rod [15] non-resistance that resets, thereby it is little to stir the moment of handle, and operation is easily, and is and simple and compact for structure, is convenient to processing.
