As a first preferred embodiment of the decompression mechanism in the present invention: as shown in fig. 6, the decompression mechanism includes a slider 202, a first decompression spring 203, a detection handle 204, and a rear cover 400: the sliding block 202 is slidably arranged at one end of the printing bracket 200 away from the pick-up rubber roller 100 and can pull the printing bracket 200 to rotate in a direction away from the pick-up rubber roller 100 during sliding; the first decompression spring 203 acts on the slider 202 to push the slider 202 to slide and drive the printing support 200 to rotate along the direction away from the pick-up rubber roller 100, and the acting force of the first decompression spring 203 on the slider 202 is greater than the acting force of the tension spring 300 on the printing support 200; the detecting handle 204 is rotatably arranged at one end of the sliding block 202 in the advancing direction pushed by the first decompression spring 203, and the rotating shaft of the detecting handle 204 is perpendicular to the rotating shaft of the printing bracket 200, so that the sliding block 202 is acted to turn over when the sliding block 202 is pushed by the first decompression spring 203 to advance; the rear cover 400 has a protrusion 401 that can act on the detecting handle 204, and the protrusion 401 can push the detecting handle 204 to move toward the slider 202 and push the slider 202 to slide along the direction of overcoming the force of the first decompression spring 203, so that the printing bracket 200 makes the printing nozzle 201 attach to the pick-up roller 100 under the action of the tension spring 300.
As shown in the figure, only the buckling leg which is linked when the sliding block 202 slides under the action of the first decompression spring 203 is arranged between the sliding block 202 and the printing support 200, so that when the acting force of the first decompression spring 203 is overcome by an external force, the printing support 200 is only acted by the tension spring 300. In order to facilitate the cooperation between the protrusion 401 and the detection handle 204, a bevel is provided at one end of the detection handle 204 near the protrusion 401, so that the protrusion 401 is pushed against the bevel to rotate.
In this way, when the rear cover 400 is detached, the slider 202 slides under the pushing of the first decompression spring 203, and drives the printing support 200 and the detection handle 204 to rotate, so that the printing nozzle 201 is separated from the pick-up rubber roller 100, and automatic decompression is realized. When the rear cover 400 is mounted, the protrusion structure 401 on the rear cover pushes the detection handle 204, and the detection handle 204 overcomes the acting force of the first decompression spring 203 and pushes the sliding block 202 to reversely slide, so that the printing support 200 automatically clings to the pick-up rubber roller 100 under the action of the tension spring 300, and the preparation of printing work is completed.
As a second preferred embodiment of the decompression mechanism in the present invention: as shown in fig. 7 and 8, the decompression mechanism includes a decompression link 500, a second decompression spring 502, and a rear cover 400; the decompression link 500 is rotatably arranged and provided with a linkage structure for linking the printing support 200; one end of the second decompression spring 502 is connected to the decompression link 500, and the other end is fixed, so as to be used for pulling the decompression link 500 to rotate, and the acting force exerted on the printing support 200 by the decompression link 500 is greater than the acting force of the tension spring 300 on the printing support 200, so that the printing nozzle 201 is driven to be separated from the pick-up rubber roller 100; the rear cover 400 has a protrusion structure 401 capable of pushing the decompression link 500, and the protrusion structure 401 can push the decompression link 500, so that the decompression link 500 rotates in a direction of overcoming the force of the second decompression spring 502, and the printing bracket 200 further enables the printing nozzle 201 to be attached to the pick-up roller 100 under the action of the tension spring 300.
In order to simplify the structure, the rotation axis of the decompression link 500 is coaxial with the rotation axis of the printing support 200, that is, the decompression link 500 is mounted on the pivot axis of the printing support 200. In addition, in order to facilitate the design of the second decompression spring 502, the force arm of the second decompression spring 502 is equal to the force arm of the tension spring 300, so that the acting force of the second decompression spring 502 is larger than the acting force of the tension spring 300 on the printing support 200. As in the first preferred embodiment of the decompression mechanism, the decompression link 500 only rotates the printing support 200 when rotated by the second decompression spring 502, but does not rotate the printing support 200 when rotated against the second decompression spring 502 by the rear cover 400, so that it is only acted upon by the tension spring 300.
Meanwhile, in order to fix the end part of the second decompression spring 502, a mounting seat 501 is provided, and the end part of the second decompression spring 502 is buckled into a hole site of the mounting seat 501 to realize fixation.
In this way, when the rear cover 400 is detached, the second decompression spring 502 stretched pulls the decompression link 500 to rotate, and can drive the printing support 200 to rotate at the same time or after rotating a certain angle, so as to realize automatic separation of the printing nozzle 201 and the pick-up roller 100. When the rear cover 400 is mounted, the protrusion structure 401 pushes the decompression link 500 to reversely rotate and stretch the second decompression spring 502, and then the printing support 200 is reset under the action of the tension spring 300, so as to complete the preparation of printing work.
As a third preferred embodiment of the decompression mechanism in the present invention: as shown in fig. 9 and 10, the decompression mechanism includes a decompression link 500, a decompression torsion spring 503, and a rear cover 400; the decompression link 500 is rotatably arranged and provided with a linkage structure for linking the printing support 200; the decompression torsion spring 503 acts on the decompression link 500, and the acting force of the decompression link 500 on the printing bracket 200 is greater than the acting force of the tension spring 300 on the printing bracket 200, so as to drive the printing nozzle 201 to be separated from the pick-up rubber roller 100; the rear cover 400 has a protrusion structure 401 capable of pushing the decompression link 500, and the protrusion structure 401 can push the decompression link 500, so that the decompression link 500 rotates in a direction of overcoming the force of the decompression torsion spring 503, and the printing bracket 200 further enables the printing nozzle 201 to be attached to the pick-up roller 100 under the action of the tension spring 300.
The decompression link 500 may be mounted on the same shaft as the printing support 200 as shown in fig. 9, or may be mounted separately as shown in fig. 10, which is not limited thereto.
As shown in fig. 11, the decompression mechanism and the tension spring 300 are arranged in the same or similar vertical plane, and the action points of the decompression mechanism and the tension spring on the printing support 200 are similar or the same, and obviously, the decompression mechanism has a simple structure and small occupied volume, and is convenient for installing other structures when being applied to a labeler.
In addition, as shown in fig. 16, because the acting force of the tension spring 300 is only located at one end of the contact surface between the printing nozzle 201 and the pick-up glue roller 100, in the actual working process, the printing nozzle 201 is tightly attached to the pick-up glue roller 100 at a position close to the tension spring 300, and the attachment between the position far away from the tension spring 300 along the axial direction of the pick-up glue roller 100 and the pick-up glue roller 100 is loose, so that the contact between the printing nozzle 201 and the pick-up glue roller 100 is uneven, and finally, printed patterns or characters and the like are generated, and in the axial direction of the pick-up glue roller 100, the position close to the tension spring 300 is tightly attached and the position far away from the tension spring 300 is white. In order to solve the problem, the present invention provides the following two technical solutions.
