Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, specifically to an automatic inkjet printing device for tubular or bar parts. Background Technology

[0002] After parts are unloaded from the automatic spray coating production line, they are marked. Typically, one employee puts the parts into a turnover basket and then transfers them to the marking machine, while another employee marks them. This creates a break in the production line, resulting in turnover waste, excessive labor, low production efficiency, and high production costs.

[0003] The existing technology has the following problems: 1. The automatic spray painting production line and the inkjet printing line are two production units, resulting in process interruptions. One person needs to hook parts off the spray painting line and place them in a turnover box, while another person loads the parts for inkjet printing, leading to long working hours and low per capita output. 2. As it is a process-based production, the parts turnover boxes store the parts, requiring a certain amount of storage space on the production floor and the use of transfer equipment, necessitating more fixed asset investment. 3. Material storage can easily lead to material confusion, and unclear labeling can cause batch number errors. 4. The loading and unloading of parts involves a high work frequency, requiring frequent bending and walking, resulting in high labor intensity. Prolonged work can easily cause lumbar muscle strain in employees, affecting their health. Utility Model Content

Detailed Implementation

[0013] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0014] Please see Figure 1-4 The present invention provides the following technical solution: Example 1: An automatic inkjet printing device for tubular or bar parts includes a conveyor line 1 with baffles on both sides. The conveyor line 1 is sequentially equipped with a feeding guide assembly 6, a pushing assembly 5, a photoelectric detection assembly 4, and an inkjet printer 2 in the conveying direction. The feeding guide assembly 6 guides the disordered parts on the conveyor line 1 into orderly parts, which then move along one side of the conveyor line 1. When a part approaches and acts on the photoelectric detection assembly 4, the pushing assembly 5 moves and pushes the part to the other side of the conveyor line 1, where the inkjet printer 2 prints the code. The feeding guide assembly 6 organizes the disordered parts into a uniform arrangement. Then, through the detection of the photoelectric detection assembly 4 and the action of the pushing assembly 5, the parts are pushed orderly towards the inkjet printer 2, completing the printing. Finally, the parts are transferred to an automatic packaging production line for boxing and packaging, eliminating process interruptions, eliminating the need for manual crating, transfer, and loading, reducing costs and increasing efficiency, and effectively ensuring product delivery rate. Specifically, the photoelectric detection component 4 includes a mounting base 4.3, which is disposed on one side of the conveyor line 1. A suspension plate 4.2 is hinged to the side of the mounting base 4.3 via a pin. A stop plate 4.4 corresponding to the part is provided on the side of the suspension plate 4.2. A proximity switch 4.1 is provided on the upper part of the mounting base 4.3. When the part moves on the conveyor line 1, it contacts the stop plate 4.4 and causes the suspension plate 4.2 to rotate. The suspension plate 4.2 touches the proximity switch 4.1 and outputs a signal. The pushing component 5 includes a cylinder 5. 1. Cylinder 5.1 is fixed on conveyor line 1. The telescopic end of cylinder 5.1 is equipped with push plate 5.2. After the parts are sorted, they continue to be conveyed. When the parts touch the baffle plate 4.4, the baffle plate 4.4 causes the suspension plate 4.2 to rotate around the pin and touch the proximity switch 4.1. The proximity switch 4.1 sends an electrical signal to the external controller. The external controller controls the cylinder 5.1 to move. This part of the control method is existing technology and will not be described in detail here. The piston rod of cylinder 5.1 extends and pushes the parts to the coding side of conveyor line 1. It should be noted that the push plate 5.2 is also equipped with a lateral blocking side plate. When the cylinder 5.1 pushes the current part to move through the push plate 5.2, the lateral blocking side plate is used to block the subsequent parts from moving forward. The push plate 5.2 integrates the lateral blocking side plate, and after the photoelectric signal is triggered, it simultaneously realizes "part pushing + subsequent blocking", ensuring that the spacing between parts is uniform (adjustable from 50-100mm), meeting the working requirements of the inkjet printer and ensuring stable printing. The combination of "feeding and guiding component 6 + pushing component 5 + photoelectric detection component 4" enables the neat arrangement of messy parts. After sorting, the parts are separated into individual disconnected arrangements by the blocking effect of the side plate of cylinder 5.1. At the same time, it achieves equidistant conveying, ensuring that the parts on conveyor line 1 can meet the basic requirements of inkjet printer 2, and guaranteeing the qualification rate and aesthetics of inkjet printing.

[0015] Example 2: Unlike Example 1, a material discharge guide assembly 3 is also provided on the conveyor line 1 between the inkjet printer 2 and the photoelectric detection assembly 4; Specifically, both the discharge guide assembly 3 and the feed guide assembly 6 include a flexible guide plate 9. The flexible guide plate 9 is connected to multiple lead screws 8, which pass through the baffle of the conveyor line 1 and are fixedly connected by nuts 7. The flared structure of the feed guide assembly 6 is used to reorganize the disordered parts, and the elastic deformation of the flexible guide plate 9 is used to adapt to parts of different diameters. The disordered parts can be automatically straightened into a straight line without manual intervention, replacing the traditional manual sorting. The flared width of the discharge guide assembly 3 is adjusted by the nuts 7 so that the parts fit tightly against the inkjet printer side of the conveyor line, so that the inkjet printer can print according to the design requirements, with uniform position and clear printing.

[0016] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
