Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a side view of a prior art door and window bracket of a tablet press.
Tablet press door and window support structure contains door and window support 1, second elastic component 2 and door and window 3.
The door and window support is a rotating support.
In fig. 1, the connecting line of the hinge point of the second elastic part and the tablet press frame 9 and the axle center point of the rotating shaft forms a force segmentation line. In this way, the hinge point of the second elastic part and the presser frame and the axis of the rotating shaft form a stress sectional surface.
The closing and opening of the door and window are maintained by the corresponding force exerted by the second elastic component, when the hinge point of the door and window support and the second elastic component is above the stress sectional surface, the door and window is subjected to the force which tends to be closed and exerted by the second elastic component, and when the connection point is below the stress sectional surface, the door and window is subjected to the force which tends to be opened and exerted by the gas spring.
Therefore, when the connecting point crosses the stressed sectional surface, the force applied to the door and window is opposite, and the buffering is not carried out, so that the required force is not easy to master during opening and closing, and the conditions that the door and window can be closed by great force and the impact force of the door and window is extremely large and the door and window is extremely difficult to open after closing are caused.
Fig. 2 is a structure view of an embodiment of a damping door window of a tablet press according to the present application.
A door and window damping structure of a tablet press is used for doors and windows of the tablet press and comprises a damping arm 4, a first limiting device 5 and a door and window support 1.
The door and window support drives the door and window to rotate. Door and window support and door and window fixed connection, during the motion of door and window support, drive door and window and follow the motion of door and window support.
The damping arm and the door and window bracket respectively move on two parallel movement planes.
For example, the damping arm rotates about an axis, forming a plane of rotation. The door and window support rotates around a shaft to form another rotating plane, and the two rotating planes are parallel.
The damping arm and the door and window support can rotate around the same shaft or respectively rotate around the two shafts.
The first limiting device is installed on the door and window support, and when the door and window support moves towards a fixed direction, the first limiting device drives the damping arm to move. For example, the fixed direction is a direction in which the door bracket tends to move toward the door closing movement.
The first limiting device is fixedly connected to the surface of the door and window support opposite to the damping arm. The vertical height of the first limiting device on the door and window support is larger than the vertical distance between the door and window support and two motion planes where the damping arm is located.
First stop device can be for protruding in the bearing on door and window support surface, also can be for protruding in the pole on door and window support surface, perhaps other structures that can let door and window support drive the damping arm when rotating to closing door and window direction. However, the bearing can reduce the friction between the first limiting device and the damping arm and reduce the wear of the equipment, and therefore, preferably, the first limiting device is a bearing.
For example, the bearing is vertically mounted on the surface of the door window bracket facing the damping arm, and the radial surface of the bearing is fixedly connected with the door window bracket. The axial length of the bearing is larger than the vertical distance between the motion plane of the door and window support and the motion plane of the damping arm.
The damping arm applies a force to the first stop means that counteracts the movement.
Because the motion of damping arm can receive the resistance, consequently when door and window support motion drives first stop device, first stop device promotes the damping arm, the resistance that the damping arm received can apply first stop device to transmit for the door and window support.
The part for providing the damping arm with resistance to the first limiting device can be an elastic part for providing pushing force or pulling force for the damping arm, or can be friction force between a shaft of the damping arm and the damping arm.
The resistance that first stop device received is thrust or pulling force.
The device further comprises a first resilient member 7. The first resilient member is mounted between the damping arm and the tablet press frame 9 to provide resistance to the first stop for the damping arm.
The first elastic component may be rubber, a spring, or a gas spring. The first elastic members listed below may be used individually or in combination.
The first elastic part is rubber, one end of the first elastic part is fixedly connected with the damping arm in a detachable mode, the other end of the first elastic part is fixedly connected with the tabletting machine frame in a detachable mode, and the connecting position of the rubber band and the tabletting machine frame is located in the opposite direction of the rotating direction of the damping arm pushed by the first limiting device. When the first limiting device pushes the damping arm, the rubber provides a pulling force for the damping arm to serve as resistance to the first limiting device.
The first elastic part is a spring, one end of the spring is movably connected with the damping arm, and the other end of the spring is fixedly connected with the frame of the tabletting machine. The connecting position of the spring and the tabletting machine frame can be positioned in the direction that the first limiting device pushes the damping arm to rotate and also can be positioned in the direction opposite to the direction that the first limiting device pushes the damping arm to rotate. By selecting springs of different lengths, the force generated by the spring in connecting the damping arm to the frame of the sheeting machine is varied. A coil spring may be used for the rotation shaft of the damping arm.
For example, when an extension spring is used, the length of the spring is less than the linear distance between the damping arm and the attachment location on the frame of the sheeter, and the spring exerts a pulling force on the damping arm after attachment. The length of the spring is larger than the linear distance between the damping arm and the connecting position on the frame of the tabletting machine, and the spring generates thrust to the damping arm after being connected. The spring is positioned in the direction opposite to the direction that the first limiting device pushes the damping arm to rotate. When the first limiting device pushes the damping arm to rotate, the spring is under the stretching action, and when the damping arm is driven by the first limiting device, the spring generates tension to the damping arm. The spring is located the first stop device and promotes damping arm rotation direction, and when first stop device promoted damping arm motion, the spring received the extrusion, and when the damping arm was driven by first stop device, the spring produced thrust to the damping arm.
The first elastic part is a gas spring, and the gas spring can provide thrust for the damping arm, so that the connecting position of the gas spring and the frame of the tablet press is located in the rotating direction of the first limiting device to push the damping arm.
Since rubber is easily aged and broken after being used for many times, and the gas spring requires a gas pump and a power supply, it is preferable that the first elastic member is a spring.
The resistance to which the first stop means is subjected may also be friction.
The damping arm provides resistance to the first stop device through friction with the shaft on which it is mounted. The friction may be bi-directional, i.e. the damping arm is subjected to friction when rotating in both directions on the axis on which it is located. The damping arm may be unidirectional, i.e. the damping arm may be subjected to friction when rotating in the direction in which the damping arm pushes the first stop means to rotate, and may not be subjected to friction when rotating in the other direction. Since the device of the present application requires the damping arm to provide resistance only when the door or window is closed, preventing the door or window from being damaged due to excessive closing force, preferably, the frictional force of the damping arm is unidirectional.
For example, the damping arm may be provided with a protrusion on the shaft, and the damping arm may be subjected to resistance from the protrusion on the shaft when moving on the shaft.
For another example, the damping arm has a protrusion on the inner side intersecting with the shaft, and the damping arm will be subjected to the resistance of the protrusion on the shaft when moving on the shaft.
The protrusions can be in a point shape or a strip shape, and if the protrusions are in a strip shape, the strip protrusions are perpendicular to the rotation direction of the damping arm.
For another example, the convex structure is shaped such that one side of the damping arm in the rotation direction is higher than the other side, and the middle is a slope. The lowest point on the convex structure is as high as the plane where the lowest point is located, and when the plane of the damping arm and the plane of the shaft where the lowest point is located move mutually, the plane rotation can be firstly contacted with the high side of the convex structure and is subjected to larger friction force. If the damping arm rotates reversely, the damping arm firstly passes through the lower side of the bulge structure when rotating, and the friction force is ignored.
Because it is costly to machine the protrusions on the damping arm or on the shaft that provide the coefficient of friction, it is preferable to provide the resistance by adding an elastic member to the damping arm.
Preferably, the damping arm and the door and window bracket are hinged on the same shaft.
For example, the door window bracket is rotated upward to close the door window. The first limiting device on the door and window support is a bearing, and the damping arm and the door and window support are both hinged on the rotating shaft 6 of the door and the window. First stop device fixed connection is on door and window support, and is located damping arm below, and first stop device drives damping arm and makes progress the rotation together, and the motion of damping arm can the decurrent pulling force that first elastomeric element gave, therefore this pulling force can be applyed for door and window support through first stop device, therefore door and window support can receive the power that decurrent power tended to open door and window promptly.
A damping door and window of a tablet press comprises the damping structure of the door and window of the tablet press, and further comprises a door and window 3 and a rotating shaft 6.
The door and window is fixedly connected with the door and window support and rotates around the rotating shaft through the door and window support. The door and window support extends from the hinge point vertically to the direction far away from the door and window, then is bent from the direction back to the opening of the door and window to surround the half cycle of the rotating shaft and is vertically and fixedly connected with the back of the door and window.
For example, the damping arm coincides with the force-receiving section plane. The door and window support and the damping arm are hinged on the same rotating shaft, a gap is formed between the damping arm and the door and window support, the door and window support is fixedly provided with a first limiting device, when the door and window support rotates towards the direction of closing the door and window, the first limiting device can push the damping arm to rotate towards the direction of closing the door and window, and the damping arm generates resistance under the action of the first elastic component. Because the position of the door and the window is opposite to the pointing direction of the damping arm, preferably, the door and window support extends from the hinge point vertically to the direction far away from the door and the window and then bends from the direction back to the opening of the door and the window to surround the rotating shaft for a half circle and is vertically and fixedly connected to the back of the door and the window.
The way of connecting the door and window and the rotating shaft by the door and window bracket is the same as the way of the prior art in figure 1.
The damping arm is hinged with the door and window bracket on the rotating shaft.
The device also comprises a second stop device 8. And the second limiting device limits the movement range of the damping arm on the rotating shaft.
For example, the second limiting means limits the range of motion of the damping arm about the axial opening direction. When the damping arm rotates to the position where the first elastic component does not apply tension to the damping arm any more in the door and window opening direction, the second limiting device can clamp the damping arm to prevent the damping arm from continuing to rotate in the door and window opening direction.
For another example, a support arm is provided below the rotating shaft and connected to the frame of the sheeting machine, and a second limiting device extending outward from the side edge of the damping arm is provided on the side wall of the damping arm near the end hinged to the rotating shaft. One end of the damping arm is hinged with the rotating shaft, and the other end of the damping arm is connected with a spring serving as a first elastic component. The other end of the spring is connected to the frame of the tabletting machine or one end of the supporting arm far away from the rotating shaft. When the damping arm is on the forced sectional surface, the second limiting device can be clamped on the side arm of the rotating shaft to prevent the damping arm from rotating downwards. When the damping arm rotates longitudinally upwards, the spring can provide a downward pulling force to the damping arm to prevent the damping arm from rotating upwards. First stop device fixed connection is on door and window support, and is located damping arm below, therefore first stop device can jack up the damping arm when door and window support upwards rotates, applys the pulling force of damping arm with the spring on the door and window support to this restriction door and window support dynamics of opening and close.
The device also comprises a second elastic member 2. One end of the second elastic component is hinged to the door and window support, the other end of the second elastic component is hinged to the sheeting machine frame on the side, far away from the door and the window, of the rotating shaft, and the second elastic component provides a thrust for the door and window support.
When two end points of the second elastic component are in the same plane with the rotating shaft of the door and window, the second elastic component is positioned on the stress sectional plane, and the door and window support is stressed in a balanced manner, so that the door and window support does not tend to open the door and window or close the door and window. When the hinge point of the second elastic component and the door and window support rotates to one side with doors and windows on the stress sectional surface along with the door and window support, the door and window support is subjected to a force tending to open the doors and the windows. When the hinge point of the second elastic component and the door and window support rotates to the side, without the door and the window, of the stress sectional surface along with the door and window support, the door and window support is subjected to force tending to close the door and the window.
The working states of the damping door and window of the tablet press comprise a first state, a second state, a third state, a fourth state, a fifth state and a sixth state.
In the first state, the door and window are closed, and the door and window support is subjected to the force of the second elastic component tending to close the door and window and is subjected to the resistance of the damping arm.
When the door and window is in the closing state in the first state, the hinge point of the second elastic part and the door and window support does not have one side of the door and window on the stress sectional surface, and the pushing force applied to the door and window support by the second elastic part enables the door and window support to open the door and window and is subjected to resistance, so that the force tends to the closing of the door and window. Door and window is when being in the closure state, and the damping arm is being pushed against all the time to first stop device on the door and window support, makes the damping arm receive the power that tends to door and window to close, and the damping arm also exerts a power that tends to door and window to open for the door and window support under first elastomeric element's effect.
In the second state, in the earlier stage of the door and window opening process, the door and window support is subjected to the force that the second elastic component tends to close the door and window and is subjected to the resistance of the damping arm.
When the door and window is in the second state, the door and window is just opened, the hinge point of the second elastic component and the door and window support is not provided with the door and window side on the stress segmented surface, and the pushing force exerted by the second elastic component on the door and window support enables the door and window support to be subjected to resistance when the door and window support is opened, so that the door and window tends to be closed. At the moment, the first limiting device on the door and window support still supports against the damping arm without being subjected to the stressed sectional surface, so that the damping arm is subjected to the force tending to the closing of the door and window, and the damping arm also applies the force tending to the opening of the door and window to the door and window support under the action of the first elastic part.
In the third state, at the later stage of the opening process of the door and the window, the door and window support is subjected to the force that the second elastic part tends to open the door and the window, and the damping arm has no acting force on the door and window support.
When the third state, door and window has opened more, there is door and window one side at the atress segmental surface at the pin joint of second elastomeric element and door and window support this moment, and the thrust that second elastomeric element applyed to the door and window support this moment impels door and window support to open door and window, is a power that makes door and window tend to open, and damping arm is blocked by second stop device this moment, along with the door and window support rotates to the direction that door and window opened, first stop device no longer contacts with damping arm, therefore damping arm does not have the effort to the door and window support this moment.
In the fourth state, the door and the window are completely opened, and the door and window support is subjected to the force that the second elastic component tends to open the door and the window.
When the door and window is in the fourth state, the door and window are completely opened, the hinge point of the second elastic part and the door and window support is provided with one side of the door and window on the stress sectional surface, the pushing force applied by the second elastic part to the door and window support causes the door and window support to open the door and window, the force is a force enabling the door and window to tend to open, the first limiting device on the door and window support is away from the range of the damping arm, and therefore the damping arm does not have acting force on the door and window support.
In the fifth state, in the early stage of the door and window closing process, the door and window support is subjected to the force that the second elastic part tends to open the door and the window, and the damping arm has no acting force on the door and window support.
In the fifth state, the door and window is just closed, the hinge point of the second elastic component and the door and window support is provided with one side of the door and window on the stress sectional surface, and the pushing force applied by the second elastic component to the door and window support at the moment impels the door and window support to open the door and window, so that the door and window tends to open. And the first stop device on the door and window support still does not return to the range of the contact damping arm at the moment, so that the damping arm has no acting force on the door and window support at the moment.
In the sixth state, at the later stage of the door and window closing process, the door and window support is subjected to the force that the second elastic component tends to close the door and window and is subjected to the resistance of the damping arm.
When the door and window is in the sixth state, the door and window are closed more, the hinge point of the second elastic part and the door and window support is not provided with one side of the door and window on the stress sectional surface, the pushing force applied by the second elastic part to the door and window support enables the door and window support to close the door and window, the force enables the door and window to tend to be closed, and the first limiting device on the door and window support is contacted with the damping arm again to support the damping arm to push against the direction in which the door and window is closed. The door window bracket thus gives the damping arm a force in the direction of closing the door window, while the damping arm has a spring exerting an opposite force, thus giving the door window bracket an opposite resistance.
