Referring to fig. 1 to 2, in some embodiments of the present invention, the device further includes a traction roller 60 and a pinch roller 61, wherein the traction roller 60 is disposed on the fixing frame 10 and located between the wiping wheel 50 and the collecting assembly 30 on the conveying path, and the wiping belt is connected to the collecting assembly 30 after bypassing the traction roller 60.
A pinch roller 61 is provided adjacent to the pull roller 60 for pinching the wiping strip against the pull roller 60 to drive the wiping strip in motion as the pull roller 60 rotates. The driving device is also used for driving the traction roller 60 to rotate.
That is, the traction roller 60 and the pinch roller 61 are disposed on the conveying path, the pinch roller 61 is parallel to the axis of the traction roller 60, a gap is defined between the wheel surface of the pinch roller 61 and the circumferential surface of the traction roller 60, the wiping passes through the gap, the gap is smaller than the thickness of the wiping belt, the pressure is applied to the wiping belt by the pinch roller 61, the wiping belt is ensured to be pressed on the circumferential surface of the traction roller, and when the driving device drives the collecting assembly 30 and the traction roller 60 to rotate, on one hand, the collecting assembly 30 winds the wiping belt, on the other hand, the rolling between the traction roller 60 and the wiping cloth can drive the wiping cloth to move towards the collecting assembly 30, in other words, the wiping cloth can be promoted to move towards the collecting assembly 30 by the traction force by the traction roller 60, and the reliability and stability of the wiping cloth moving in the conveying direction are further improved.
It will be appreciated that at least one of the peripheral surface of the pulling roll 60 and the tread of the pinch roller 61 is provided with a soft adhesive layer, by which the friction force can be increased, ensuring a better pulling and conveying effect, and possibly protecting the wiping cloth from damage.
Referring to fig. 1 to 2, in one embodiment of the present invention, a gap adjusting assembly 11 is provided on a fixing frame 10, and a pinch roller 61 is provided on the gap adjusting assembly 11 to change the pressure of the pinch roller 61 against the wiping strip by adjusting the gap between the pinch roller 61 and a bracket of the traction roller 60 by the gap adjusting assembly 11.
That is, the gap adjusting unit 11 can adjust the gap between the pinch roller 61 and the traction roller 60, for example, by making the pinch roller 61 approach the traction roller 60 through the gap adjusting unit 11, the gap between the pinch roller 61 and the traction roller 60 increases the pressure of the pinch roller 61 to the wiping belt, and making the pinch roller 61 away from the traction roller 60 through the gap adjusting unit 11, the gap between the pinch roller 61 and the traction roller 60 increases, the pressure of the pinch roller 61 to the wiping belt decreases, so that free adjustment of the pressure of the pinch roller 61 to the wiping belt can be achieved, and by adjusting the pressure of the wiping belt by the pinch roller 61, the reliability of the conveying of the wiping belt can be ensured, and in addition, the conveying speed can also be adjusted and controlled to some extent. In addition, in the installation process of the wiping strip, after the gap between the pinch roller 61 and the traction roller 60 is adjusted to be larger, the wiping strip is put into the gap, so that the wiping strip is conveniently installed between the pinch roller 61 and the traction roller 60, and the installation is convenient.
Referring to fig. 1 to 6, in some embodiments of the present invention, the collecting assembly 30 includes a first pivot shaft 301, a collecting cylinder, a first driving wheel 303, and a first damping adjustment assembly 304, wherein the first pivot shaft 301 is pivoted on the fixing frame 10 and can pivot around its own axis, and the collecting cylinder is fixed on the first pivot shaft 301 to wind up the wiping strip as the first pivot shaft 301 rotates.
The first driving wheel 303 is sleeved on the first pivot shaft 301, and the driving device is connected with the first driving wheel 303 and is used for driving the first driving wheel 303 to rotate, and the first pivot shaft 301 is driven to rotate by the first driving wheel 303. A first damping assembly is provided between the first pivot shaft 301 and the first drive wheel 303 for adjusting a first damping of relative rotation between the first drive wheel 303 and the first pivot shaft 301.
That is, there is a circumferential rotation damping (i.e., a first damping) between the first driving wheel 303 and the first pivot shaft 301, and the first driving wheel 303 can drive the first pivot shaft 301 to rotate by using the rotation damping between the first driving wheel 303 and the first pivot shaft 301, and then the first pivot shaft 301 drives the take-up cylinder to rotate to take up the wiping strip thereon. It should be noted that the magnitude of the first damping affects the carrying capacity of the first pivot shaft 301, when the first damping is smaller, the carrying capacity of the first pivot shaft 301 is smaller, and when the first damping is larger, the standby capacity of the first pivot shaft 301 is larger. When the load applied to the first pivot shaft 301 is smaller, the first driving wheel 303 rotates to drive the first pivot shaft 301 to rotate synchronously with the load, so as to drive the receiving cylinder to wind. When the load applied to the first pivot shaft 301 is excessive, the first driving wheel 303 and the first pivot shaft 301 rotate relatively, that is, the first driving wheel 303 rotates, and the first pivot shaft 301 and the first driving wheel 303 cannot rotate synchronously.
In the process of cleaning the residual glue of the dispensing needle, the dispensing needle is attached to the wiping belt of the wheel face of the wiping wheel 50, and in some cases, if the residual glue on the dispensing needle is too much and is solidified to form a large block-shaped structure and the like, the residual glue is not easy to be removed, and at this time, when the wiping wheel 50 and the wiping belt are rubbed with the residual glue, a large acting force is generated, which is very likely to cause damage to the dispensing needle.
In this embodiment, the first damping between the first driving wheel 303 and the first pivot shaft 301 may be adjusted by the first damping adjusting component 304, so that the first damping reaches a predetermined value, under the predetermined value, if the residual glue on the dispensing needle is solidified and the volume is large, so that the friction force between the residual glue and the wiping belt is too large, and the first pivot shaft 301 is loaded too much, the first driving wheel 303 and the first pivot shaft 301 rotate relatively, that is, the first pivot shaft 301 does not rotate synchronously with the first driving wheel 303 any more, at this time, since the speed of the first pivot shaft 301 is less than that of the first driving wheel 303, even the first pivot shaft 301 stops rotating, so that the purpose of protecting the dispensing needle can be achieved, and the dispensing needle is prevented from being damaged.
Referring to fig. 5 to 6, in one embodiment of the present invention, a first pivot shaft 301 has a first end D301, a second end D302, and a shoulder between the first end D301 and the second end D302; the receiving cylinder is mounted at the first end D301, and the first driving wheel 303 is sleeved at the second end D302 and is rotatable and axially slidable relative to the first pivot shaft 301 in a circumferential direction.
