Technical Field

[0001] The utility model belongs to the technical field of printing inkjet equipment, and specifically relates to an automatic width-adjusting clamping plate mechanism. Background Technique

[0002] Inkjet printing requires an inkjet printer. An inkjet printer is a high-tech digital printing device of the "non-contact with the object" inkjet printing type. Therefore, it can be unrestricted by any material. Under the control of an inkjet controller, ink is ejected from the nozzles of the print head and printed on the printing substrate. According to the printing requirements, a driver conveys the printing substrate, and a system controller is responsible for the operation of the whole machine.

The distance is controlled by two cylinders. Usually, only one side can be fixed and the other side can move. During use, it cannot move centered. Even if it can move centered, the overall mechanism has a large size and a relatively complex structure. Content of the Utility Model

[0030] The synchronous belt drive assembly 400 includes a first synchronous pulley 402 and a second synchronous pulley 405. A synchronous belt member 403 is sleeved on the first synchronous pulley 402 and the second synchronous pulley 405.

[0031] In this embodiment, preferably, a plurality of support columns 103 are provided between the bottom plate 101 and the support fixing plate 102 by screws.

[0032] In this embodiment, preferably, a second pressing plate fixing seat 209 and a first pressing plate fixing seat 208 are respectively provided on the rear surfaces of the first slide plate 201 and the second slide plate 202 by screws. And the extending distance of the second pressing plate fixing seat 209 backward is longer than that of the first pressing plate fixing seat 208, which is convenient for the two synchronous belt pressing plates 204 to be respectively fixed on the front and back sides of the synchronous belt member 403. During the transmission of the synchronous belt member 403, the moving directions of the front and back sides of the synchronous belt member 403 are opposite. Therefore, it will drive the two synchronous belt pressing plates 204 to move relatively or away from each other. Synchronous belt pressing plates 204 are provided on the rear surfaces of the second pressing plate fixing seat 209 and the first pressing plate fixing seat 208. A jaw mounting adapter seat 206 is provided on the lower surfaces of the first slide plate 201 and the second slide plate 202 by screws. A jaw mounting seat 205 is provided at the bottom of the jaw mounting adapter seat 206. Jaw bodies 207 are provided on the lower surfaces at both ends of the jaw mounting seat 205. The jaw bodies 207 are barbed hook mechanisms.

[0033] In this embodiment, preferably, a floating joint 303 is provided at the rear end of the piston rod inside the cylinder block 304. The front end of the floating joint 303 is an external thread and the end is an internal thread. The rear end of the floating joint 303 is connected to a cylinder connecting plate 302. The external thread of the floating joint 303 is connected to the hole on the cylinder connecting plate 302 by a nut. Two magnetic switches 305 are provided on the cylinder block 304, which are mainly used for the position detection and position feedback of the cylinder. Throttle valves 306 are provided at the air inlet and exhaust ports of the cylinder block 304 and the slide table cylinder 307, which are mainly used for the speed adjustment of the cylinder. The piston rod inside the slide table cylinder 307 is connected to the cylinder fixing adapter plate 301. The position of the cylinder fixing adapter plate 301 can be changed within a certain range by using the slide table cylinder 307, so as to change the stroke position of the piston rod extending inside the cylinder block 304.

[0034] In this embodiment, preferably, the synchronous belt drive assembly 400 includes a first synchronous pulley pin shaft 401 and a second synchronous pulley pin shaft 404 respectively embedded and installed inside the first synchronous pulley 402 and the first synchronous pulley 402. A retaining ring 406 is provided at the upper ends of the first synchronous pulley pin shaft 401 and the second synchronous pulley pin shaft 404. The retaining ring 406 restricts axial movement. The lower ends of the first synchronous pulley pin shaft 401 and the second synchronous pulley pin shaft 404 are both external thread structures.

A board dropping sensor 502 is provided on the surface of the fixed bracket 501, which mainly feeds back the detection and feedback of the board dropping during the working process.

[0036] In summary, when the cylinder block 304 is in the retracted state, the driving slide cylinder 307 extends. At this time, the first slide plate 201 connected to the piston rod inside the slide cylinder 307 moves outward along the double-slider guide rail 203, changing the distance between the two jaw bodies 207; when the cylinder block 304 is in the extended state, the piston rod inside the slide cylinder 307 does not move. The piston rod inside the cylinder block 304 is connected to the cylinder connection plate 302, and the cylinder connection plate 302 is connected to the first slide plate 201. Therefore, as the cylinder connection plate 302 moves, it drives the first slide plate 201 to move along the double-slider guide rail 203. The first slide plate 201 is connected to the synchronous belt member 403. Therefore, the first slide plate 201 drives the synchronous belt member 403 to rotate, and the second slide plate 202 connected to the synchronous belt member 403 moves. Moreover, the moving direction of the second slide plate 202 is opposite to that of the first slide plate 201. Therefore, the distance between the two jaw bodies 207 is changed, thereby adjusting the width between them. By controlling the extension and retraction of the cylinder block 304 and the slide cylinder 307 in the pneumatic drive assembly 300, the automatic width adjustment is achieved; the position and state of the cylinder are fed back through the magnetic switch 305; the state of the board during work is detected and fed back through the board dropping sensor 502.

[0037] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
