DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Example 1

[0032] like Figure 1-6 As shown, in this embodiment, a laser coding system for a filling production line, such as a glass bottle beer filling production line, is provided, which mainly includes a rotary capping machine 1, a laser coding device 2, a detection device 3 and a dust collection device 4.

[0033] The rotary capping machine 1 is provided with a rotating wheel 11, and a conveyor belt 12 on the filling production line is partially wound around the rotating wheel 11. The conveyor belt 12 is meshedly connected with the rotating wheel 11. Through the continuous rotation of the rotating wheel 11, the conveyor belt 12 also synchronously performs continuous product conveying operations.

[0034] As a preferred solution, the conveyor belt 12 is arranged in a "U" shape, and the curved portion of the conveyor belt 12 arranged in the "U" shape is meshed and connected with the rotating wheel 11; the meshing length value of the conveyor belt 12 and the rotating wheel 11 is greater than or equal to the semicircular circumference value of the rotating wheel 11. The laser coding device 2 is arranged outside the contact area between the conveyor belt 12 and the rotating wheel 11.

[0035] In addition, the rotary capping machine 1 is also provided with a clamping device 13 for clamping a single product conveyed on the conveyor belt 12, and the clamping device 13 rotates synchronously with the rotating wheel 11; so that when each glass bottle 5 enters the rotary capping machine 1 from the conveyor belt 12, there is a clamping device 13 to clamp the glass bottle 5; to ensure the state of the glass bottle 5 at this time, which is convenient for the capping operation and laser coding operation. In this embodiment, the clamping device 13 includes a capping mechanism 131 arranged on the rotary capping machine 1, and a connecting piece 132 corresponding to the capping mechanism 131 is also arranged on the top of the rotary capping machine 1; so that when it is necessary to detect or monitor a single clamping device 13, the monitoring of the single clamping device 13 can be achieved by detecting the connecting piece 132. In addition, the detection device 3 is installed corresponding to the connecting piece 132. Since the connecting piece 132 is arranged on the top of the rotary capping machine 1, the operator can easily perform installation and subsequent maintenance operations.

[0036] The laser coding device 2 includes a laser lens 21 for laser coding the glass bottle 5 product, a height adjustment device 22 for adjusting the vertical position height of the laser lens 21, and a plane adjustment device for adjusting the horizontal position of the laser lens 21.

[0037] As a preferred solution, a protective sleeve 211 is provided corresponding to the laser lens 21, and the protective sleeve 211 is coaxially provided on the height adjustment device 22 with the laser lens 21, and the length of the protective sleeve 211 extending from the height adjustment device 22 is greater than the length of the laser lens 21 extending from the height adjustment device 22. The protective sleeve 211 can reduce the probability of liquid splashing onto the laser lens 21 when a glass bottle 5 explodes; and can make high-pressure air spray from the inside to the outside along the inside of the protective sleeve 211 to form a positive pressure environment, further preventing the splashing of liquid and dust from contaminating the laser lens 21 when the bottle explodes, resulting in the laser beam not being able to be completely printed on the product, ensuring the concentration of laser energy and guaranteeing the stability of laser printing.

[0038] Furthermore, the laser coding device 2 includes a rectangular frame 25, which can be welded from steel; four universal wheels 251 are arranged at the bottom of the frame 25, and the universal wheels 251 are arranged corresponding to the four corners of the frame 25 respectively; the bottom of the frame 25 is also provided with a number of hand-cranked anchor fixings 252 for fixing the frame 25. The height adjustment device 22 and the plane adjustment device are arranged on the frame 25, and the plane adjustment device includes a transverse adjustment device 23 for adjusting the position of the laser lens 21 in the plane X-axis direction and a longitudinal adjustment device 24 for adjusting the position of the laser lens 21 in the plane Y-axis direction. The height adjustment device 22, the transverse adjustment device 23 and the longitudinal adjustment device 24 are all in the form of a slide plate, and the movement of the slide plate is realized by setting a transmission screw to achieve the adjustment of the laser lens 21.

[0039] The detection device 3 includes a detection unit 31 and an encoder 32. The detection unit 31 is fixedly arranged on the rotary capping machine 1 and is used to detect the pressing device 13; as a preferred solution, the detection unit 31 is arranged on the rotation track of the connecting piece 132 and is electrically connected to the laser lens 21. The detection unit 31 includes a first detection unit and a second detection unit that are arranged opposite to each other; the first detection unit is provided with a transmitting electric eye 311, and the transmitting electric eye 311 is extended and arranged above the movement track of the connecting piece 132, and the second detection unit is provided with a receiving electric eye 312, and the receiving electric eye 312 is extended and arranged below the movement track of the connecting piece 132. When the rotating wheel 11 rotates, the connecting piece 132 passes between the transmitting electric eye 311 and the receiving electric eye 312.

[0040] The encoder 32 is arranged at the bottom of the rotary capping machine 1 and connected to the rotating wheel 11, and the encoder 32 is electrically connected to the detection unit 31. In addition, it is required to set the encoder 32 separately to avoid interference of electrical faults on the encoder 32; at the same time, the added encoder 32 can perform program interlocking protection on the detection unit 31. During the operation of the equipment, trigger failure is prone to occur, resulting in missed coding; and the encoder 32 is loose, resulting in the encoder 32 not rotating, or the encoder 32 fault signal is unstable, resulting in coding extrusion and thus affecting the coding quality. In this embodiment, the trigger signal of the detection unit 31 is set to interlock protection with the encoder 32. The two signals must appear at the same time to form a certain pulse ratio. When the deviation is normal, the alarm signal is transmitted; when the trigger is normal, but the encoder 32 slips, the interlocking program detects that the signal does not match, that is, the alarm reminds to stop; when the encoder 32 signal is normal, but there is no trigger signal, the interlocking program detects that the signal does not match, and the alarm reminds to stop; thereby effectively ensuring the stability of the coding quality.

[0041] The dust suction device 4 includes a dust suction part 41, a dust collecting part 42 and a fan. The dust suction part 41 is connected to the dust collecting part 42 through a pipeline, and the dust absorbed by the dust suction part 41 is collected into the dust collecting part 42 by the fan. For the glass bottle 5 product in this embodiment, a mounting seat 121 for placing the glass bottle 5 is provided on the conveyor belt 12, and a labeling machine for attaching a label to the glass bottle 5 is provided on the outside of the input end of the conveyor belt 12, and the laser lens 21 is used to print the code on the label. Since laser printing on the label will generate paper scraps and dust, it will pollute the working environment and affect the physical and mental health of employees; and dust can easily cause wear of rotating components of the equipment such as gears and bearings, shorten the service life of equipment components, and increase the failure rate of the equipment. Therefore, the dust suction part 41 is correspondingly arranged at the working position where the laser lens 21 acts on the label, so as to effectively treat the dust harmlessly.

[0042] Other structural forms of the rotary capping machine 1 and the labeling machine in this embodiment can be found in the prior art and will not be described in detail here.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
