Description

Technical Field

[0001] This utility model belongs to the field of glassware processing technology, and in particular relates to a printing device for glassware processing. Background Technology

[0002] Glassware inkjet printing is a process of creating glass products by spraying pigments, inks, and other materials onto the glass surface. It is mainly used in architectural decoration, billboards, and signage and advertising in commercial or outdoor locations.

[0003] Existing inkjet printing equipment has several drawbacks. For example, printing on glassware requires manual operation by workers, who must constantly adjust the angle of the glassware during printing, making the process cumbersome, time-consuming, and labor-intensive. Furthermore, the ink may be released into the air during operation, posing a health risk if inhaled by workers. Therefore, we propose an inkjet printing device for glassware processing. Utility Model Content

[0004] The purpose of this invention is to provide a printing device for glassware processing to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a printing device for glassware processing, including a base and a printing gun, and further including:

[0006] A fixed column is fixedly installed on the top of the base. A sliding plate is slidably installed inside the fixed column. The inkjet gun is fixedly installed on the sliding plate. A rotating column is rotatably installed on the base and on one side of the inkjet gun.

[0007] A fixed plate is fixedly installed on the top of the base. A protective cover is slidably installed on the fixed plate. A first threaded rod is rotatably installed on the bottom of the fixed plate. The upper end of the first threaded rod passes through the protective cover and the fixed plate and extends to the outside. The first threaded rod is threadedly connected to the protective cover. A protective cover is fixedly installed on the top of the protective cover. A negative pressure fan is fixedly installed inside the protective cover. A fixed frame is inserted into the top of the protective cover. A second activated carbon filter is fixedly installed inside the fixed frame.

[0008] A drive assembly, located within the base, is used to drive the sliding plate to slide and the rotating column to rotate;

[0009] A fixing component, located inside the protective cover, is used to fix the position of the fixing frame.

[0010] In this technical solution, during the printing process, a negative pressure fan is started. The negative pressure fan can slowly draw outside air into the protective cover through the first activated carbon filter. Then, the harmful gases in the protective cover enter the second activated carbon filter and are then discharged to the outside. The second activated carbon filter can filter the harmful gases to ensure that the gas discharged to the outside does not contain harmful substances.

[0011] When the second activated carbon filter needs to be replaced after a long period of time, the fixing frame can be removed by the fixing component, and a new fixing frame can be inserted into the protective cover. The fixing component can fix the position of the fixing frame, ensuring that the fixing frame will not be displaced during use, which makes it convenient to replace the second activated carbon filter. The operation is simple and does not require the use of tools.

[0012] When printing on glassware, the glassware is first placed on top of the rotating column. The rotating column, driven by the drive mechanism, rotates the glassware. The drive mechanism also drives the sliding plate to slide up and down repeatedly, which in turn drives the inkjet gun to slide up and down repeatedly. The inkjet gun can then print on the glassware. As the glassware rotates, the inkjet gun slides up and down, ensuring that the entire sidewall of the glassware is printed.

[0013] In the above technical solution, the driving component further includes:

[0014] The power chamber is located inside the base. A motor is fixedly installed inside the power chamber. A first gear is fixedly installed on the output shaft of the motor. A second gear is meshed on one side of the first gear. The upper end of the second gear passes through the power chamber and is fixedly connected to the rotating column.

[0015] A disc is fixedly mounted on the bottom end of a first gear. A connecting rod is rotatably mounted on the bottom of the disc. A rack is rotatably mounted on one end of the connecting rod. A third gear is meshed on one side of the rack. The upper end of the third gear passes through the power chamber and is fixedly mounted with a second threaded rod. The upper end of the second threaded rod passes through a sliding plate and is threadedly connected to the sliding plate.

[0016] In this technical solution, when printing on glassware, the glassware is first placed on top of the rotating column, and then the motor is started. The motor is powered on and drives the first gear to rotate. The first gear drives the second gear meshing with it to rotate. The second gear drives the rotating column to rotate, and the rotating column drives the glassware to rotate. At the same time, the first gear drives the disc to rotate, and the disc drives the connecting rod to rotate. The connecting rod pulls the rack to slide back and forth. The rack drives the third gear meshing with it to rotate back and forth. The third gear drives the second threaded rod to rotate back and forth. Under the action of the thread, the second threaded rod drives the sliding plate to slide up and down back and forth. The sliding plate drives the inkjet gun to slide up and down back and forth. The inkjet gun can print on the glassware. While the glassware can rotate, the inkjet gun slides up and down back and forth, ensuring that the entire side wall of the glassware can be printed.

[0017] In the above technical solution, the fixing component further includes:

[0018] A limiting groove is provided, which is located inside the protective cover and at the bottom of the fixed frame. A limiting plate is slidably installed in the limiting groove. The top of the limiting plate extends into the fixed frame and is inserted into the fixed frame. Several guide posts are fixedly installed at the bottom of the limiting plate. Each of the guide posts is fitted with a spring. The two ends of the springs are fixedly connected to the limiting groove and the limiting plate, respectively.

[0019] In this technical solution, when the second activated carbon filter needs to be replaced after a long period of time, first pull down the limiting plate. The limiting plate drives several guide posts to slide downwards, and at the same time, several springs are compressed and contracted. After the limiting plate disengages from the fixed frame, the fixed frame can be removed, and a new fixed frame can be inserted into the protective cover. Then, the limiting plate is released, and under the action of the rebound force of several springs, the limiting plate slides upwards and inserts into the fixed frame, which can fix the position of the fixed frame and ensure that the fixed frame will not be displaced during use. This facilitates the replacement of the second activated carbon filter, and the operation is simple and requires no tools.

[0020] In the above technical solution, a non-slip rubber pad is further fixedly installed on the top of the rotating column.

[0021] In this technical solution, the anti-slip rubber pads ensure the glassware is fixed and stable.

[0022] In the above technical solution, an operating disc is further fixedly installed at the top end of the first threaded rod.

[0023] In this technical solution, the operating panel facilitates the rotation of the first threaded rod by the operator.

[0024] In the above technical solution, a first activated carbon filter screen is further fixedly installed on one side of the protective cover.

[0025] In this technical solution, it is ensured that dust from the outside air will not enter the protective cover.

[0026] In the above technical solution, the first gear, the second gear, the disk and the third gear are all rotatably connected to the power cavity, the rack is slidably connected to the power cavity, the second threaded rod is rotatably connected to the fixed column, and the plurality of guide columns are slidably connected to the limiting groove.

[0027] In this technical solution, it is ensured that the first gear, the second gear, the disc, and the third gear can all rotate within the power cavity, the rack can slide within the power cavity, the second threaded rod can rotate within the fixed column, and several guide columns can slide within the limiting groove.

[0028] The beneficial effects of this utility model are:

[0029] 1. The inkjet printing device for glassware processing, when printing, starts a negative pressure fan, which slowly draws outside air into the protective cover through a first activated carbon filter. Then, the harmful gases in the protective cover enter the second activated carbon filter and are then discharged to the outside. The second activated carbon filter can filter the harmful gases to ensure that the gas discharged to the outside does not contain harmful substances.

[0030] 2. This inkjet printing device for glassware processing, when it is necessary to print on glassware, first places the glassware on top of a rotating column. Through the set drive component, the rotating column can be driven to rotate, and the rotating column drives the glassware to rotate. Through the set drive component, the sliding plate can be driven to slide up and down reciprocally. The sliding plate drives the inkjet gun to slide up and down reciprocally. The inkjet gun can print on the glassware. While the glassware can rotate, the inkjet gun slides up and down reciprocally to ensure that the side wall of the glassware can be completely printed, and the glassware can be automatically printed.
