Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a feeding and positioning mechanism for a printer. Background Technology

[0002] In automated printing equipment (such as industrial inkjet printers and laser marking machines), the self-contained feeding conveyor belt integrated at the equipment's inlet plays a crucial role in the orderly and stable transport of products to be printed to the printing station. This conveyor belt, typically of limited length and an integral part of the overall printing equipment, directly determines the positional accuracy and orientation of the product as it enters the printing area, thus having a decisive impact on the final print quality (such as character clarity, pattern position accuracy, and barcode readability).

[0003] However, since the initial loading position of the product (especially when placed manually) may deviate from the centerline, within the short length of the conveyor belt, slight initial angle or lateral errors, as well as the inertial forces generated by the start, stop or speed changes of the conveyor belt, can cause the product to slide, rotate or move laterally before reaching the printing area. This results in a positional shift of the product in the printing area, leading to serious defects such as printing errors, blurring, ghosting or even missing information, significantly reducing the yield and increasing production costs and rework rates.

[0004] In existing technologies, fixed guide baffles or simple limiting strips are usually set on the conveyor belt to position the products. Although guide baffles and simple limiting strips can position and guide the products, they are difficult to adapt to the switching of different product shapes and sizes, which affects production efficiency. Utility Model Content

[0005] The purpose of this application is to provide a feeding and positioning mechanism for a printer, which can position the product so that the conveyor belt does not easily deviate when transporting the product to the printing area, thus ensuring the yield rate, reducing production costs, and being able to quickly adapt to the switching of different product shapes and sizes, thereby improving production efficiency.

[0006] The technical solution adopted by this utility model is: a feeding and positioning mechanism for a printer, disposed on a printer, the printer including a printer body and a conveyor belt, one side of the printer body being a feeding end, and the feeding and positioning mechanism including:

[0007] The first support plate and the second support plate are respectively fixed on both sides of the feeding end of the printer body;

[0008] The first movable plate and the second movable plate are movably disposed between the first support plate and the second support plate and located above the conveyor belt;

[0009] First baffle and second baffle, respectively installed on the first movable plate and the second movable plate, are used for positioning the product;

[0010] And a drive assembly for driving the first movable plate and the second movable plate to move to change the position of the first baffle plate and the second baffle plate relative to the conveyor belt.

[0014] And a connecting plate sleeved on the guide rod, wherein the outer ends of the first threaded rod and the second threaded rod are rotatably connected to the connecting plate;

[0015] The first threaded rod and the first movable plate, and the second threaded rod and the second movable plate are all threaded connections.

[0016] Optionally, the drive assembly further includes a first handwheel and a second handwheel respectively fitted onto the ends of the first threaded rod and the second threaded rod that are far apart from each other.

[0017] Optionally, both the first and second movable plates are provided with through holes, and a guide sleeve for sliding cooperation with the guide rod is provided in the through hole.

[0034] This embodiment provides a feeding and positioning mechanism 10 for a printer, referring to... Figures 1-3It is installed on the printer, which includes a printer body 100 and a conveyor belt 101 installed on the printer body 100. One side of the printer body 100 is the loading end 102 and the other side is the unloading end 103. The printer body 100 has a printing area and a print head inside. When working, the product is placed on the conveyor belt 101 from the loading end 102 of the printer body 100. The conveyor belt 101 transports the product to the printing area inside the printer body 100 for printing. Then the printed product is transported to the unloading end 103 for unloading.

[0035] In this embodiment, the feeding and positioning mechanism 10 includes a first support plate 11 and a second support plate 12 fixedly disposed on both sides of the feeding end 102 of the printer body 100, a first movable plate 13 and a second movable plate 14 movably disposed between the first support plate 11 and the second support plate 12 and located above the conveyor belt 101, a first baffle plate 15 and a second baffle plate 16 respectively disposed on the first movable plate 13 and the second movable plate 14 for positioning the product, and a driving component for driving the first movable plate 13 and the second movable plate 14 to move to change the position of the first baffle plate 15 and the second baffle plate 16 relative to the conveyor belt 101.

[0036] The first support plate 11 and the second support plate 12 are symmetrically arranged on both sides of the conveyor belt 101. The first movable plate 13 and the second movable plate 14 can move along the conveying direction perpendicular to the conveyor belt 101. The first baffle plate 15 and the second baffle plate 16 are respectively fixedly connected to the first movable plate 13 and the second movable plate 14, so that when the first movable plate 13 and the second movable plate 14 move along the conveying direction perpendicular to the conveyor belt 101, they drive the first baffle plate 15 and the second baffle plate 16 to move, so that the first baffle plate 15 and the second baffle plate 16 can position products of different shapes and sizes, thereby ensuring printing quality and yield, and reducing rework rate and production cost.

[0037] Furthermore, the drive assembly includes a guide rod 171 fixedly disposed between the first support plate 11 and the second support plate 12; a first threaded rod 172 passing through the first movable plate 13, one end of the first threaded rod 172 being rotatably connected to the first support plate 11, and the other end extending to the outside of the first movable plate 13; a second threaded rod 173 passing through the second movable plate 14, one end of the second threaded rod 173 being rotatably connected to the second support plate 12, and the other end extending to the outside of the second movable plate 14; and a connecting plate 174 sleeved on the guide rod 171, the outer ends of the first threaded rod 172 and the second threaded rod 173 being rotatably connected to the connecting plate 174; wherein the first threaded rod 172 and the first movable plate 13, and the second threaded rod 173 and the second movable plate 14 are all threadedly connected.

[0038] When the first threaded rod 172 and the second threaded rod 173 are driven to rotate, since the first threaded rod 172 and the second threaded rod 173 are threadedly connected to the first movable plate 13 and the second movable plate 14 respectively, the first movable plate 13 and the second movable plate 14 will move along the axial direction of the first threaded rod 172 and the second threaded rod 173 (i.e., perpendicular to the conveying direction of the conveyor belt 101). At the same time, since the connecting plate 174 is sleeved on the guide rod 171, and the guide rod 171 is fixed between the first support plate 11 and the second support plate 12, the connecting plate 174 can limit the offset of the first movable plate 13 and the second movable plate 14 during the movement, ensuring that they can move smoothly in the predetermined direction, thereby realizing the adjustment of the position of the first baffle plate 15 and the second baffle plate 16.

[0039] Furthermore, the drive assembly also includes a first handwheel 175 and a second handwheel 176 respectively fitted onto the ends of the first threaded rod 172 and the second threaded rod 173 that are far apart from each other.

[0040] By rotating the first handwheel 175 and the second handwheel 176, the first threaded rod 172 and the second threaded rod 173 can be easily driven to rotate, thereby achieving precise adjustment of the positions of the first movable plate 13 and the second movable plate 14. This manual adjustment method is not only easy to operate but also low in cost, facilitating daily maintenance and adjustment by users. At the same time, the arrangement of the first handwheel 175 and the second handwheel 176 increases the flexibility of the equipment, allowing users to adjust the position of the baffle plate at any time according to actual needs to meet the feeding and positioning requirements of printing materials of different sizes. This enables the feeding and positioning mechanism 10 to quickly adapt to changes in different product shapes and sizes, improving production efficiency.

[0041] Furthermore, both the first movable plate 13 and the second movable plate 14 are provided with through holes, and guide sleeves 131 for sliding cooperation with guide rods 171 are provided in the through holes.

[0042] The guide sleeve 131 further enhances the stability of the first movable plate 13 and the second movable plate 14 during movement. The sliding fit between the guide sleeve 131 and the guide rod 171 not only reduces friction and makes the movement smoother, but also ensures that the first movable plate 13 and the second movable plate 14 can move precisely along the direction of the guide rod 171, avoiding deviation and wobbling. This design not only improves the accuracy of the feeding and positioning mechanism 10, but also extends the service life of the equipment. At the same time, the replaceable design of the guide sleeve 131 allows users to easily replace it when it is worn or damaged, thereby ensuring the continuous and stable operation of the equipment.

[0043] Furthermore, there are two guide rods 171, which are symmetrically arranged, and the first threaded rod 172 and the second threaded rod 173 are located between the two guide rods 171.

[0044] Two guide rods 171 are symmetrically arranged to provide reliable guidance and support for the first movable plate 13 and the second movable plate 14, ensuring their stability and accuracy during movement. Meanwhile, the first threaded rod 172 and the second threaded rod 173 are located between the two guide rods 171. This layout not only makes the entire mechanism more compact but also facilitates user operation and adjustment, ensuring the efficient operation of the feeding and positioning mechanism 10.

[0045] Furthermore, fixed bearings 18 are provided at the connection points of the first threaded rod 172 and the first support plate 11, the connection points of the second threaded rod 173 and the second support plate 12, and the connection points of the first threaded rod 172 and the second threaded rod 173 and the connecting plate 174.

[0046] The fixed bearing 18 significantly improves the rotational flexibility and stability between the threaded rod and the support plate and connecting plate 174. At the connection between the first threaded rod 172 and the first support plate 11, the fixed bearing 18 ensures that the first threaded rod 172 does not experience excessive resistance during rotation, while also withstanding the pressure from the first movable plate 13, maintaining stable operation of the mechanism. Similarly, at the connection between the second threaded rod 173 and the second support plate 12, the fixed bearing 18 plays the same role. Furthermore, at the connections between the first threaded rod 172 and the second threaded rod 173 and the connecting plate 174, the addition of the fixed bearing 18 not only enhances the connection strength between the threaded rod and the connecting plate 174, but also makes the threaded rod rotate more smoothly, reducing errors caused by vibration or shaking.

[0047] Furthermore, both the first movable plate 13 and the second movable plate 14 are provided with waist-shaped mounting holes 132, and the first baffle plate 15 and the second baffle plate 16 are provided with mounting screw holes 151 that mate with the waist-shaped mounting holes 132.

[0048] The design of the oblong mounting hole 132 allows for greater flexibility in the installation of the first movable plate 13 and the second movable plate 14, enabling fine-tuning (height adjustment) as needed to achieve optimal positioning. Simultaneously, the oblong mounting hole 132, in conjunction with the mounting screw hole 151, not only enhances the connection stability between the first baffle plate 15 and the second baffle plate 16 and the movable plate, but also facilitates disassembly and replacement, improving the overall ease of maintenance of the feeding and positioning mechanism 10.

[0049] Furthermore, both the first baffle plate 15 and the second baffle plate 16 include an integrally formed arc-shaped guide portion 161 and a straight guide portion 162. The arc-shaped guide portion 161 is located on one side near the end of the conveyor belt 101, and the distance between the arc-shaped guide portions 161 of the first baffle plate 15 and the second baffle plate 16 is greater than the distance between the straight guide portions 162 of the first baffle plate 15 and the second baffle plate 16.

[0050] The arc-shaped guide 161 is used to guide the product to be printed to smoothly transition from the conveyor belt 101 to the feeding and positioning mechanism 10, while the straight guide 162 ensures the stability and accuracy of the material during the positioning process. It closely conforms to the product's travel path and effectively prevents the material from shifting or tilting during the movement.

[0051] Furthermore, the first baffle plate 15 and the second baffle plate 16 are symmetrically arranged, and the cross-sections of the arc-shaped guide portion 161 and the straight guide portion 162 of the first baffle plate 15 and the second baffle plate 16 are both L-shaped.

[0052] The L-shaped cross-section design not only enhances the structural strength of the baffle plate but also ensures closer contact between the baffle plate, the movable plate, and the conveyor belt 101, further improving positioning accuracy and stability. The L-shaped cross-section also better guides the material along the predetermined path, reducing material jamming or misalignment during transitions, thereby improving printing efficiency and quality.

[0053] Furthermore, the bottom of the first baffle plate 15 and the second baffle plate 16 are provided with a plurality of guide bearings 19. There is a gap between the guide bearings 19 and the conveyor belt 101, and the plurality of guide bearings 19 are distributed at equal intervals along the length direction of the first baffle plate 15 and the second baffle plate 16.

[0054] Understandably, the guide bearing 19 allows the first baffle plate 15 and the second baffle plate 16 to more flexibly adapt to the dynamic changes of the material during material conveying, while maintaining an appropriate gap with the conveyor belt 101, avoiding wear or increased resistance due to friction or excessive contact. Furthermore, the outer ring of the guide bearing 19 contacts the product, effectively preventing damage and ensuring the quality of the finished product.

[0055] Working Principle: During printing, the product to be printed is placed on the conveyor belt 101 and moves towards the printing area as the conveyor belt 101 moves. When the product contacts the arc-shaped guide 161 of the first baffle plate 15 and the second baffle plate 16, the arc-shaped guide 161 guides the product smoothly to the straight guide 162, where it is precisely positioned to ensure that the product does not shift or tilt during transport, thus guaranteeing the quality and yield of the finished product. Simultaneously, by driving the first movable plate 13 and the second movable plate 14 through the drive assembly, the positions of the first baffle plate 15 and the second baffle plate 16 can be adjusted according to products of different shapes and sizes, thereby quickly adapting to changes in product shape and size and meeting diverse printing needs.

[0056] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
