Description

Technical Field

[0001] The present application relates to the field of printer technology, and in particular to a novel multi-module bottle printer. Background Art

[0002] With the rapid development of printing technology, printers have emerged, greatly improving printing efficiency. Printing technology has continuously advanced, from early inkjet printing to modern laser printing. For example, inkjet printing technology has evolved from continuous inkjet to piezoelectric ink dot control technology, and then to bubble jet technology.

[0003] Furthermore, advances in laser digital printing technology have significantly improved printing speed and quality. However, digital printers are typically slow, often requiring over ten seconds to complete a print. This can be inconvenient, especially when printing large quantities of documents quickly. To improve printing quality, digital printers typically employ a double-row horizontal roller connection and group multiple items to be printed. This increases printing efficiency by increasing the number of items that can be printed at a time.

[0004] However, the printing device is connected by a double row of horizontal rollers, and the double or even multiple rows of rollers need to be precisely aligned. Otherwise, the printing medium position may be offset during the digital printing process, thereby affecting the printing quality and even causing the product to be scrapped in severe cases.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0029] Considering that existing rollers are placed side by side horizontally, each row of rollers needs to be aligned, otherwise the printing process will result in printing at different locations on the product to be printed, affecting print quality. The present application changes the arrangement of the rollers, placing different rollers side by side horizontally, while widening the printing width of the print head so that the print head can cover the bottles to be printed on all rollers. Since all rollers are arranged side by side, even if different rollers are not precisely aligned, they will not print at different locations on the bottle to be printed, thus avoiding the technical problem of the print medium position shifting between different rollers, which affects print quality.

[0030] like Figures 1 to 4 As shown, the novel multi-module bottle printer of the embodiment of the present application comprises: a printing head 1, a plurality of roller assemblies 2 and a driving device. The printing head 1 prints along a first direction, and the plurality of roller assemblies 2 are located below the printing head 1 and arranged adjacent to each other in a second direction, which is perpendicular to the first direction. For example, Figure 1 As shown, the first direction is the up and down direction, and the second direction is the left and right direction. The printing width of the printing head 1 covers the sum of the lengths of all roller assemblies 2, ensuring that the printer head 1 can cover all the bottles 8 to be printed during the printing process to avoid missing printing.

[0031] Furthermore, each roller assembly 2 includes a plurality of rollers 21 and a drive worm 22. The plurality of rollers 21 are arranged adjacent to each other in the second direction. The plurality of rollers 21 are used to place the bottles 8 to be printed. The drive worm 22 is located at the same end of the plurality of rollers 21 along the first direction. A turbine 221 is provided at one end of each roller 21 opposite the drive worm 22, and is connected to the drive worm 22 through the turbine 221.

[0032] In combination with the above embodiment, the driving device is connected to the transmission worm 22 and is used to drive multiple transmission worms 22 for transmission. For example, it can be a driving motor, a motor, etc. After the driving device is working, it drives a transmission worm 22 directly connected to it (directly connected) to rotate. In principle, each transmission worm 22 can be equipped with a driving device to achieve direct drive of all transmission worms 22. However, the direct drive method requires precise control of the output torque of each driving device, and the control cost of the driving device is high and the control difficulty is relatively large. In actual use, the roller assembly 2 on the end side is often used, such as Figure 1 A driving device is set at the leftmost or rightmost position, and the driving device is directly connected to the transmission worm 22 here, and the opposite ends of any other two adjacent transmission worms 22 are connected by a coupling. The driving device drives the directly connected transmission worm 22 to rotate, and then the transmission worm 22 drives the remaining transmission worms 22 to rotate in turn, and finally each transmission worm 22 drives the corresponding roller 21 to rotate synchronously in the same direction, finally realizing the transmission of the bottle body 8 on the roller 21.

[0033] In the novel multi-module bottle printer of the embodiment of the present application, each roller assembly 2 further includes a support frame 4. Each roller 21 is located at the top of the corresponding support frame 4 and is rotatably connected to the support frame 4 at both ends. Each drive worm 22 is located within the corresponding support frame 4 and is rotatably connected to both sides of the support frame 4 at both ends. The support frame 4 supports the corresponding roller 21, the drive device, and the corresponding drive worm 44, while ensuring a certain aesthetic performance.

[0034] In the novel multi-module bottle printer of the embodiment of the present application, each support frame 4 includes a base plate 41, two side plates 42 and two end plates 43. The two side plates 42 are respectively arranged on both sides of the top surface of the base plate 41, and the two end plates 43 are respectively arranged at the two ends of the top surface of the base plate 41; the two ends of each roller 21 are respectively rotatably connected to the top ends of the corresponding two side plates 42, and the two ends of each transmission worm 22 are respectively rotatably connected to the corresponding two end plates 43.

[0035] In the new multi-module bottle printer of the embodiment of the present application, each group of roller assemblies 2 also includes multiple auxiliary supports 5, and the multiple auxiliary supports 5 are arranged in sequence along the second direction on the top surface of the corresponding base plate 41 and are located directly below the corresponding transmission worm 22. The top end of each auxiliary support 5 is connected to the bottom of the corresponding transmission worm 22.

[0036] In combination with the above embodiment, the two ends of each transmission worm 22 are supported by the corresponding end plates 43 on both sides. If the transmission worm 22 is longer as a whole, the middle part thereof will sag due to its own weight, thereby affecting the normal transmission of the transmission worm 22. Auxiliary supports 5 are provided in plurality and are arranged at equal intervals along the axial direction of the corresponding transmission worm 22, which plays the role of supporting the middle part of the transmission worm 2, effectively avoiding, for example, the transmission worm 22 from sagging, and extending the service life of the transmission worm 22.

[0037] In the novel multi-module bottle printer of the present embodiment, each auxiliary support 5 includes a support base 51 and two support rollers 52. The two support rollers 52 are axially parallel and arranged at the top of the support base 51. The bottom of each transmission worm 22 is located between the corresponding two support rollers 52. Each pair of support rollers 52 can rotate relative to the support base 51. During rotation, the transmission worm 22 generates rolling friction with the corresponding two support rollers 52, resulting in low resistance and not affecting the normal rotation of the transmission worm 22.

[0038] In the novel multi-module bottle printer of the present embodiment, each drive worm 22 is provided with a limiting annular groove 221 on its circumferential outer wall. The number of limiting annular grooves 221 is the same as the number of auxiliary supports 5 and corresponds one-to-one. Each pair of support rollers 52 is axially parallel and arranged opposite each other, extending into the corresponding limiting annular groove 221 and being fixedly connected to the limiting annular groove 221. Each pair of support rollers 52 is fixed by the corresponding limiting annular groove 221, effectively preventing the support rollers 52 from deviating during rotation and also allowing for rapid positioning and installation of the support rollers 52.

[0039] In the novel multi-module bottle printer of the embodiment of the present application, the driving shaft 3 of the driving device is arranged parallel to the axis of the corresponding transmission worm 22 on the outer wall of an end plate, and the driving shaft 3 and the transmission worm 22 are connected by a conveyor belt.

[0040] In the novel multi-module bottle printer of the embodiment of the present application, the distance between any two adjacent rollers 21 is smaller than the minimum outer diameter of the bottle 8, thereby preventing the bottle 8 to be printed from falling between the rollers 21 and causing a shutdown.

[0041] The novel multi-module bottle printer of the embodiment of the present application further includes a movable beam 6 , on which the print head 1 is disposed. The movable beam 6 moves along a first direction to drive the print head 1 to print along the first direction.

[0042] The novel multi-module bottle printer of the embodiment of the present application further includes a frame 7 and a control device. The movable beam 6, multiple groups of roller assemblies 2 and the control device are respectively arranged on the frame 7. The control device is used to control the operation of the movable beam 6 and the driving device.

[0043] The novel multi-module bottle printer provided in the embodiment of the present application changes the arrangement of the rollers 21, with different rollers 21 placed side by side horizontally, while widening the printing width of the printing head 1, so that the printing head 1 can cover the bottles 8 to be printed on all rollers 21. Since all the rollers 21 are arranged side by side, even if different rollers 21 are not precisely aligned, they will not print at different positions on the bottle 8 to be printed, thereby avoiding the technical problem of print medium position offset between different rollers 21, thereby affecting the print quality.

[0044] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
