Description

Technical Field

[0001] This utility model relates to the field of icon printing technology, specifically to an automated loading and unloading device for icon printing. Background Technology

[0002] Icons, or labels, are affixed to the surface of goods, boxes, or various equipment and items to identify them. The images on the labels are formed by printing on blank label paper.

[0003] However, existing label printing and unloading devices use independent electrical control, that is, PLC controls the printing head to print, and after printing, the take-up roller is controlled to rotate a certain number of times to collect the labels. This kind of automatically printed and fed label receiving equipment with electrical control is expensive, requires frequent maintenance, and is not easy to use. On the other hand, some mechanical printing devices do not use electrical control and rely on manual feeding and receiving. This printing method greatly reduces production efficiency and is also not easy to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose an automated loading and unloading device for icon printing. Utility Model Content

[0005] The purpose of this invention is to provide an automated loading and unloading device for icon printing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated loading and unloading device for icon printing, comprising a worktable, a positioning roller mounted on the left side of the upper surface of the worktable, a support frame fixedly mounted in the middle of the upper surface of the worktable, a half-shaft gear motor fixedly mounted on the rear right side of the upper surface of the support frame, a printing mechanism disposed in the middle of the surface of the support frame, a receiving mechanism mounted at the right end of the upper surface of the worktable, and a limit mechanism mounted on the upper surface of the worktable located on the right side of the support frame.

[0007] Preferably, the printing mechanism includes a printing head that is slidably disposed through the center of the support frame surface. A toothed groove is provided on the right side of the surface of the printing head, and the toothed groove meshes with the gear head of the half-shaft gear motor. A convex plate is fixedly installed on both the front and rear sides of the upper end of the printing head, and a thrust spring is fixedly installed on the lower surface of the convex plate. The lower end of the thrust spring is fixedly connected to the support frame.

[0008] Preferably, the receiving mechanism includes an assembly frame fixedly installed on the right end of the upper surface of the worktable, a shaft rotatably installed on the left end of the inner surface of the assembly frame, and a take-up roller rotatably installed on the right end of the inner surface of the assembly frame.

[0009] Preferably, the receiving mechanism further includes pulleys that are fixedly installed through the assembly frame at the front ends of the shaft and the winding roller. The pulleys are connected by a transmission belt. A driven gear is fixedly installed in the middle of the surface of the shaft, and the driven gear also meshes with the gear head of the half-shaft gear motor.

[0010] Preferably, the limiting mechanism includes a bracket fixedly installed on the upper surface of the worktable on the right side of the support frame, a connecting plate fixedly installed on the lower surface of the bracket, and the same pressure roller rotatably installed on the opposite side of the connecting plate, wherein an electric heating wire is provided inside the pressure roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the arrangement of a half-shaft gear motor, a printing mechanism, and a take-up mechanism, enables the half-shaft gear motor to rotate, causing the gear head to engage with the tooth groove, thereby pushing the entire printing head downward to print the icons on the labels on the worktable. When the gear part of the gear head rotates to the other side, the tooth groove loses engagement with the gear head, and under the action of the thrust spring, it pushes the entire printing head upward. At this time, the gear head engages with the driven gear and rotates, which in turn drives the pulley through the shaft. Under the traction of the transmission belt, the take-up roller rotates, thereby collecting the labels and pulling subsequent unprinted labels to the right. As the printing head moves, the half-shaft gear motor continues to rotate, causing the gear head to re-engage the tooth groove. At this point, the take-up roller stops winding, and the subsequently transported labels stop moving. The printing head then moves downwards again to print the labels. This process repeats. The half-shaft gear motor rotates at the same speed, ensuring that the printing mechanism and the take-up mechanism work at the same rate. This means that the label is pulled and moved the same distance each time, ensuring equidistant printing of the labels. This significantly improves the label printing quality and enables automatic completion of take-up, feeding, and printing in one integrated process, greatly improving the efficiency of the printing work and reducing manual labor.

[0013] 2. This utility model, through the setting of a limiting mechanism, a bracket, a connecting plate, and a pressure roller, ensures that when the printed label is wound up, the label is limited below the pressure roller, thereby preventing the printed label from moving obliquely upwards after passing through the printing mechanism and directly connecting with the receiving mechanism, which would cause it to tilt and curl up. This ensures that the subsequent labels remain flat and neat when printed inside the printing mechanism, thereby improving printing stability and printing quality. In addition, the electric heating wire in the pressure roller can heat up the pressure roller, which can also dry the printing coating on the label surface while limiting the label.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 As shown, an automated loading and unloading device for icon printing includes a worktable 1. A positioning roller 2 is installed on the left side of the upper surface of the worktable 1. A support frame 3 is fixedly installed in the middle of the upper surface of the worktable 1. A half-shaft gear motor 4 is fixedly installed at the rear right side of the upper surface of the support frame 3. A printing mechanism 5 is provided in the middle of the surface of the support frame 3. A receiving mechanism 6 is installed at the right end of the upper surface of the worktable 1. A limit mechanism 7 is installed on the upper surface of the worktable 1 located to the right of the support frame 3.

[0021] By adopting the above technical solution, the positioning roller 2 ensures the stability of the label material feeding.

[0022] Furthermore, the printing mechanism 5 includes a printing head 501 that is slidably disposed through the center of the surface of the support frame 3. A toothed groove 502 is provided on the right side of the surface of the printing head 501, and the toothed groove 502 meshes with the gear head of the half-shaft gear motor 4. A protruding plate 503 is fixedly installed on both the front and rear sides of the upper end of the printing head 501. A thrust spring 504 is fixedly installed on the lower surface of the protruding plate 503, and the lower end of the thrust spring 504 is fixedly connected to the support frame 3. A rod is fixedly disposed on the surface of the support frame 3 inside the thrust spring 504, and the upper end of the rod slides through the protruding plate 503.

[0023] By adopting the above technical solution, the half-shaft gear motor 4 rotates and the gear head engages with the tooth groove 502, thereby pushing the entire printing head 501 downward to print the icon on the label on the worktable 1. When the gear part of the gear head rotates to the other side, the tooth groove 502 loses engagement with the gear head, and under the action of the thrust spring 504, it will push the entire printing head 501 upward. As the half-shaft gear motor 4 rotates continuously, the printing head 501 continuously cycles up and down. The rod in the middle of the thrust spring 504 limits the up and down movement of the printing head 501 through the convex plate 503 to ensure stable movement.

[0024] Furthermore, the receiving mechanism 6 includes an assembly frame 601 fixedly installed on the right end of the upper surface of the workbench 1. A shaft 602 is rotatably installed on the left end of the inner surface of the assembly frame 601, and a take-up roller 603 is rotatably installed on the right end of the inner surface of the assembly frame 601. The receiving mechanism 6 also includes pulleys 604 fixedly installed on the assembly frame 601 through the front ends of the shaft 602 and the take-up roller 603. The pulleys 604 are connected by a transmission belt. A driven gear 605 is fixedly installed in the middle of the surface of the shaft 602. The driven gear 605 also meshes with the gear head of the half-shaft gear motor 4.

[0025] By adopting the above technical solution, the gear part of the gear head of the half-shaft gear motor 4 rotates to the right, which can engage the driven gear 605 to rotate, and then drive the pulley 604 through the shaft 602. Under the traction of the transmission belt, the take-up roller 603 rotates, thereby collecting the labels and pulling the subsequent unprinted labels to the right to enter the printing mechanism 5 for printing.

[0026] As the half-shaft gear motor 4 continues to rotate, the gear head will re-engage with the tooth groove 502. At this time, the winding roller 603 will stop winding, the labels being transported will stop moving, and the printing head 501 will move downwards again to print the labels, and so on.

[0027] The half-shaft gear motor 4 rotates at the same speed, which makes the printing mechanism 5 and the receiving mechanism 6 work at the same speed, meaning that the label moves the same distance each time it is pulled, thus ensuring that the label is printed at equal intervals.

[0028] Furthermore, the limiting mechanism 7 includes a bracket 701 fixedly installed on the upper surface of the worktable 1 on the right side of the support frame 3, a connecting plate 702 fixedly installed on the lower surface of the bracket 701, and the same pressure roller 703 rotatably installed on the opposite side of the connecting plate 702, with an electric heating wire inside the pressure roller 703.

[0029] By adopting the above technical solution, the label will be limited below the pressure roller 703, thereby preventing the printed label from moving directly upwards and connecting directly with the receiving mechanism 6 after passing through the printing mechanism 5, thus preventing it from tilting and lifting up. This ensures that the subsequent labels remain flat when printed inside the printing mechanism 5.

[0030] The electric heating wire in the pressure roller 703 can heat up the pressure roller 703, which can dry the printing coating on the label surface while limiting the position.

[0031] Working Principle: When using this automated label printing loading and unloading device, firstly, the labels to be printed are collected by the take-up roller and mounted on an external roller frame. The label end is manually pulled through the positioning roller 2, into the support frame 3, and then through the pressure roller 703 before connecting to the take-up roller 603. Then, the half-shaft gear motor 4 is started. The half-shaft gear motor 4 rotates, and the gear head engages with the tooth groove 502, thereby pushing the entire printing head 501 downward to print the labels on the worktable 1. When the gear part of the gear head rotates to the other side, the tooth groove 502 loses engagement with the gear head, and under the action of the thrust spring 504, it pushes the entire printing head 501 upward. At this time, the gear head engages with the driven gear 605 and rotates, which in turn drives the pulley 604 through the shaft 602. Under the traction of the transmission belt, the take-up roller 603 rotates, thereby aligning with the label. The label is collected and can pull the subsequent unprinted labels to the right. The half-shaft gear motor 4 continues to rotate, which will cause the gear head to re-engage the tooth groove 502. At this time, the take-up roller 603 will stop the take-up operation, and the subsequent transported labels will stop moving. The printing head 501 will then move downwards again to print the labels. This process is repeated. When the printed labels are taken up, the labels will be limited below the pressure roller 703, thereby preventing the printed labels from moving directly upwards after passing through the printing mechanism 5 and directly connecting with the take-up mechanism 6, causing them to tilt at an angle. This ensures that the subsequent labels remain flat and neat when printed inside the printing mechanism 5. In addition, the electric heating wire in the pressure roller 703 can heat up the pressure roller 703, which can also dry the printing coating on the label surface while limiting the label. This is the working principle of the automated label printing loading and unloading device.
