[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the technical solutions of the present invention, and cannot be interpreted as limiting the present invention.

[0026] like Figure 1 As shown, a new ZJ17 tipping paper width automatic adjustment guide block device includes a tipping paper width detector 7, a tipping paper guide block assembly 2, a width adjustment screw 3, a servo driver 4, and a tipping paper guide block rangefinder 6 device.

[0027] Figure 2 The tipping paper width detector 7 adopts a transparent organic glass hollow tube 71, and the transmitting end 72 of the light curtain sensor is installed inside to measure the tipping paper width. The transparent organic glass hollow tube is installed below the tipping paper guide block, and bearings are installed at both ends, which can rotate flexibly. The tipping paper passes on it, which plays a role of guiding the tipping paper. The transmitting end of the tipping paper width light curtain sensor is integrated and fixed on the transparent organic glass hollow tube axis, and does not rotate with the hollow tube. The tipping paper width is measured by the light curtain emitted by the transmitting end. The infrared light emitted by the transmitter forms a light curtain system, which is irradiated on the tipping paper. The tipping paper blocks a part of the infrared light so that it receives the reflection and generates a signal, and the unblocked part does not reflect. Finally, the width of the blocked tipping paper is calculated by calculating the reflected infrared light.

[0028] like Figure 3As shown, the tipping paper guide block assembly 2 is composed of a guide block and a blocking guide rail, which is used to bear the tipping paper and automatically adjust the tipping paper in cooperation with the automatic width adjustment device. The guide block includes a guide block body 21 and a fixing bracket 5, and two long holes 23 are respectively opened on both sides of the working surface of the guide block body for the blocking guide rail to adjust the width thereon.

[0029] The paper guide block body is installed on the upper end surface of the fixed bracket, and an adjusting screw through hole is arranged on the fixed bracket. The fixed bracket has a through hole connected to the tipping paper guide block deviation correction handle mechanism.

[0030] The blocking guide rail is divided into inner and outer sides. The inner blocking guide rail is composed of a first blocking block 11 and two guide rails 13, and the outer blocking guide rail is composed of a second blocking block 12 and two guide rails. Blocking cylinders are installed at the front and rear ends of each side of the guide rail, mainly used to block and restrict the displacement of the tipping paper. Threaded holes with opposite directions are processed under the inner and outer guide rails, the inner side is a forward threaded hole, and the outer side is a reverse threaded hole, which cooperates with the screw of the automatic width adjustment device to play the role of simultaneous approach and separation.

[0031] like Figure 4 As shown, the width adjustment screw 3 includes an adjustment screw body 31 and a driven gear 32 fixed to one end of the adjustment screw body. On the adjustment screw body, a positive thread 33 is processed near one end of the driven gear, and a reverse thread 34 is processed near the other end. The width adjustment screw 3 connects two blocking guides through a double-headed positive and reverse screw, and automatically adjusts and blocks the width of the tipping paper under the drive of the servo driver; when the driven gear rotates, it drives the width adjustment screw to rotate, thereby acting on the inner and outer blocking guides to move closer or separate. The width adjustment screw 3 connects two blocking guides through a double-headed positive and reverse screw, and automatically adjusts and blocks the width of the tipping paper under the drive of the servo driver.

[0032] A transmission gear is installed at the end of the driver transmission shaft, which is connected to the driven gear of the width adjustment screw and can rotate forward and backward. Tipping paper guide block rangefinder. It is used to measure the distance between the paper guide block blocking rails, and feed back the data to the tipping paper width detector for comparison. The rangefinder 6 is installed on the blocking rail 1, the transmitting end is installed under the inner blocking rail, and the receiving end is installed under the outer blocking rail; the paper guide block width is measured by the time from the signal emitted by the transmitting end to the signal received by the receiving end. Thereby, it is compared with the measured width of the tipping paper, and the signal data is fed back to the private service driver 4, so that its rotation drives the width adjustment screw to rotate, so that the blocking rails are brought together or separated to the same width of the tipping paper.

[0033] The method of using this technical solution is as follows Figure 3As shown: when the equipment changes the specification of tipping paper, when the tipping paper passes through the tipping paper width detector 7, the tipping paper detector automatically detects the tipping paper width through the infrared light curtain and feeds back the signal to the tipping paper guide block distance meter 6. The tipping paper guide block distance meter measures the guide block width through the emitted light and compares it with the tipping paper width detector 7, and then feeds back the compared signal to the servo driver. If the width of the tipping paper guide block distance meter is smaller than the width measured by the tipping paper width detector, the servo driver 4 rotates clockwise, driving the width adjustment screw 3 to rotate counterclockwise, so that the blocking guide rail 1 on the guide block is pulled open. At the same time, the tipping paper guide block distance meter continues to measure the guide block width. When the data obtained is the same as the data measured by the tipping paper width detector, the servo driver stops working. The same applies to the opposite.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, but these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
