[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] According to an embodiment of the present invention, the adjustable printing line fixture structure includes a printing adjustment mechanism 1, a centering guide mechanism 2, a clamping mechanism 3, and a barcode scanning mechanism 4. The printing adjustment mechanism 1 includes an adjustment seat 10, a Z-axis adjustment member 11, and a Y-axis adjustment member 12. The Z-axis adjustment member 11 is arranged beside the printing line 6, and the Y-axis adjustment member 12 is slidably connected to the Z-axis adjustment member 11. The adjustment seat 10 moves along the Y-axis adjustment member 12. The centering guide mechanism 2 is arranged on the first side of the adjustment seat 10 to adjust the position of the product to be printed. The centering guide mechanism 2 includes a bracket 20 arranged above the printing line 6 and a guide. The stop block 21 and guide stop block 21 can move relative to the bracket 20 along the Y-axis direction. The two guide stops 21 abut against the guide rail arranged on the printing line 6 to clamp the product to be printed. The clamping mechanism 3 is arranged on both sides of the adjusting seat 10. The clamping mechanism 3 includes a clamping wheel 30 and a lifting frame 31. The clamping wheel 30 is connected to the lifting frame 31. The lifting frame 31 drives the clamping wheel 30 to move relative to the printing line 6 in the Z-axis direction. The lifting frame 31 is located beside the printing line 6. The barcode scanning mechanism 4 includes a barcode scanner 40 and an adjusting frame 41. The adjusting frame 41 is arranged above the printing line 6. The barcode scanner 40 moves along the adjusting frame 41 relative to the Y-axis direction of the printing line 6.

[0029] With the conveying direction of printing line 6 as the X-axis, the width direction of printing line 6 as the Y-axis, and the height direction of printing line 6 as the Z-axis, Z-axis adjusting member 11 and Y-axis adjusting member 12 respectively achieve adjustment in the Z-axis and Y-axis directions. Z-axis adjusting member 11 is arranged on one side of printing line 6 to support and adjust the Z-axis position of Y-axis adjusting member 12 and adjusting seat 10. Z-axis adjusting member 11 drives Y-axis adjusting member 12 to change the vertical distance of adjusting seat 10 relative to printing line 6. By precisely controlling the vertical distance between the printhead and the product to be printed, it can adapt to products of different heights or meet the printing distance requirements of different printing processes. Y-axis adjusting member 12 changes the position of adjusting seat 10 to adjust the horizontal position of printhead in the Y-axis direction. It can flexibly adjust the horizontal position of printhead according to the width of the product to be printed or the printing position requirements, ensuring the accuracy and consistency of printing.

[0030] The bracket 20 of the centering guide mechanism 2 is arranged above the printing line 6 to support the guide block 21. The guide block 21 moves smoothly in the Y-axis direction. The guide block 21 can increase the clamping range by pushing the guide rail to clamp the product to be printed. The guide rail extends the clamping and constraint range of the guide block 21 on the product, which can accurately position the product to be printed on the printing line 6 and keep it in a stable position during the printing process, avoiding inaccurate printing or poor barcode quality due to product position deviation.

[0031] The clamping mechanism 3 adjusts the position of the clamping roller 30 in the Z-axis direction through the lifting frame 31. The clamping roller 30 applies a certain pressure to the product during the printing process to ensure that the product is closely attached to the printing line 6 during printing, and to avoid affecting the printing effect due to product shaking or loosening.

[0032] The scanning mechanism 4 scans the barcode using the barcode scanner 40. After the barcode is printed onto the product, when the product passes through the barcode scanner 40, the scanner scans the printed barcode on the product to obtain product information, which can then be recorded. Through the detection function of the barcode scanner 40, errors or defects that may occur during the printing process can be detected in a timely manner, such as blurry, deformed, or misaligned barcodes, thereby achieving effective monitoring and control of printing quality.

[0033] In some embodiments, the Z-axis adjusting member 11 includes a first adjusting frame 110, a first lead screw 111, a first sliding sleeve 112, and a first transmission wheel 113. The first adjusting frame 110 is fixed to the printing line 6. The first lead screw 111 extends along the Z-axis direction. The first end of the first lead screw 111 is pivotally connected to the first adjusting frame 110. The other end of the first lead screw 111 passes through the first adjusting frame 110 and is connected to the first transmission wheel 113. The first sliding sleeve 112 is threadedly connected to the first lead screw 111 and is drively connected to the Y-axis adjusting member 12.

[0034] Specifically, the first adjustment frame 110 is fixed to the printing line 6. The first adjustment frame 110 extends along the Z-axis. The first adjustment frame 110 includes two frames arranged on both sides of the printing line 6. The first lead screw 111 passes through the frame and rotates freely within the frame. The first transmission wheel 113 is used to drive the first lead screw 111 to rotate. The first transmission wheel 113 includes a wheel body and a handle. The wheel body is a circular wheel. The center of the wheel body is fixedly connected to the end of the first lead screw 111. The handle allows the user to rotate it manually. The wheel body can be fitted with a transmission belt or other components to cooperate with a motor to achieve electric drive. The first sliding sleeve 112 is sleeved on the first lead screw 111. The first sliding sleeve 112 has an internal thread, which matches the external thread on the surface of the first lead screw 111 to achieve a threaded connection between the first sliding sleeve 112 and the first lead screw 111. The rotation of the first transmission wheel 113 drives the first lead screw 111 to rotate, thereby driving the first sliding sleeve 112 to change its position relative to the first lead screw 111, achieving precise position adjustment to meet the printing requirements. Furthermore, the threaded connection method can stably maintain the set printing distance for a long time, avoiding a decrease in printing quality due to loosening or instability of the adjustment mechanism.

[0035] Optionally, a distance detection device, such as an ultrasonic rangefinder, can be installed on the first adjustment frame 110 to measure the height of the product to be printed. The most suitable printing height can be obtained based on the height. The first lead screw 111 can be rotated to adjust the distance based on the printing height, so as to achieve adaptive adjustment for products of different heights.

[0036] In some embodiments, the Y-axis adjusting member 12 includes a second adjusting frame 120, a second lead screw 121, a second sliding sleeve 122, and a second transmission wheel 123. The second adjusting frame 120 is connected to the first sliding sleeve 112. The second lead screw 121 extends along the Y-axis direction. The first end of the second lead screw 121 is pivotally connected to the second adjusting frame 120. The other end of the second lead screw 121 passes through the second adjusting frame 120 and is connected to the second transmission wheel 123. The second sliding sleeve 122 is threadedly connected to the second lead screw 121. The adjusting seat 10 is connected to the second sliding sleeve 122.

[0037] Specifically, the second adjusting frame 120 extends along the Y-axis and is connected to the first sliding sleeve 112 to move along the Z-axis. The second lead screw 121 passes through the second adjusting frame 120 and rotates freely within it. The second sliding sleeve 122 has an internal thread, which matches the external thread on the surface of the second lead screw 121 to achieve a threaded connection between the second sliding sleeve 122 and the second lead screw 121. The rotation of the second transmission wheel 123 drives the second lead screw 121 to rotate, thereby causing the second sliding sleeve 122 to change position relative to the second lead screw 121, achieving precise position adjustment to meet printing requirements. Furthermore, the threaded connection method can stably maintain the set printing distance for a long time, avoiding a decrease in printing quality due to loosening or instability of the adjusting mechanism. Understandably, the second transmission wheel 123 drives the second lead screw 121 to rotate. The second transmission wheel 123 includes a wheel body and a handle. The wheel body is a circular wheel, and its center is fixedly connected to the end of the second lead screw 121. The handle allows the user to rotate it manually. The wheel body can be fitted with a transmission belt or other components to cooperate with a motor for electric drive. The second sliding sleeve 122 drives the adjusting seat 10 to adjust its position in the Y direction, ensuring precise printing position. The coordinated use of the Y-axis adjusting component 12 and the Z-axis adjusting component 11 completes the position adjustment in both directions, and the position adjustment in both directions can be performed simultaneously, accelerating the printing position adjustment speed.

[0038] In some embodiments, the lifting frame 31 includes a lifting frame 310, a first support rod 311 and a second support rod 312. The first support rod 311 is located beside the printing line 6 and extends along the Z-axis. A first movable seat 313 is sleeved on the first support rod 311. The second support rod 312 is connected to the first movable seat 313 and extends along the Y-axis. A second movable seat 314 is sleeved on the second support rod 312 and is connected to the lifting frame 310.

[0039] Specifically, the lifting frame 310 drives the pressure roller 30 and provides stable support and positioning. The first support rod 311, located beside the printing line 6, provides support and guidance for the lifting frame 310 in the Z-axis direction. The first movable seat 313 can move on the first support rod 311. The first movable seat 313 can be fixed to the first support rod 311 in an adjustable position through threaded connection, bolt fixing, snap-fit, or other methods. The first movable seat 313 can be fixed by bolting it against the first support rod 311. To move the first movable seat 313, loosen the bolts. The first movable seat 313 changes the position of the lifting frame 310 and the second support rod 312 in the Z-axis direction.

[0040] The second support rod 312 extends along the Y-axis. The second movable seat 314 on the second support rod 312 is used to change the position of the lifting frame 310 in the Y-axis direction. The second movable seat 314 can be fixed to the second support rod 312 through threaded connection, bolt fixing, snap-fit, etc., to achieve an adjustable position. For example, the second movable seat 314 can be fixed by bolting it against the first support rod 311. To move the second movable seat 314, loosen the bolt. Moving the second movable seat 314 changes the position of the lifting frame 310, ensuring that the pressure roller 30 evenly presses the product. The cooperation of the first support rod 311 and the second support rod 312 enables synchronous adjustment of the Z-axis and Y-axis.

[0041] In some embodiments, the top of the lifting frame 310 is connected to the second movable seat 314, and the bottom of the lifting frame 310 is connected to a plurality of pressure rollers 30.

[0042] Specifically, the second movable seat 314 is fixedly connected to the top of the lifting frame 310, which can be achieved through welding, bolting, or other methods. Multiple pressure rollers 30 are connected to the bottom of the lifting frame 310. These rollers 30 act simultaneously on the product to be printed, ensuring that the product is evenly pressed during the printing process. The design of multiple pressure rollers 30 increases the stability of the pressure, preventing product deformation or uneven printing due to uneven local pressure from a single pressure roller 30. The multiple pressure rollers 30 create multi-point pressure to prevent product damage and increase the contact area between the lifting frame 310 and the product, increasing friction and preventing product movement.

[0043] Optionally, the surface of the pressure roller 30 may be provided with anti-slip textures such as diamond grids or dot matrix protrusions to increase the friction between the pressure roller 30 and the product, preventing the product from sliding during the printing process.

[0044] In some embodiments, the centering guide mechanism 2 further includes a third lead screw 22, a third sliding sleeve 23, and a third transmission wheel 24. The third lead screw 22 is a bidirectional lead screw. The first end of the third lead screw 22 is pivotally connected to the bracket 20, and the other end of the third lead screw 22 passes through the bracket 20 and is connected to the third transmission wheel 24. Two third sliding sleeves 23 are sleeved on the third lead screw 22 and move relative to it. The guide block 21 is connected to the third sliding sleeve 23.

[0045] Specifically, the third lead screw 22 is a bidirectional lead screw with opposite directions of external threads at both ends. When the third lead screw 22 rotates, the two third sliding sleeves 23 move in opposite directions, facilitating simultaneous adjustment of the two guide blocks 21 to move towards or away from each other, achieving rapid centering adjustment of the product. The guide blocks 21 move under the drive of the third sliding sleeves 23, adapting to the clamping requirements of products of different widths. The third lead screw 22 is driven by the third transmission wheel 24, which can be manually or electrically driven. The third lead screw 22, in conjunction with the third sliding sleeves 23, achieves rapid centering, enabling quick clamping of the product. The guide blocks 21, in conjunction with the guide rail, can drive the guide rail to move rapidly. The guide blocks 21 can be fixed to the guide rail with bolts or clips, facilitating rapid movement of the guide blocks 21 to change the clamping width to adapt to the product.

[0046] In some embodiments, a sliding mechanism 5 is also included. Two sliding mechanisms 5 are arranged on both sides of the adjusting seat 10, corresponding to the pressing mechanism 3. The sliding mechanism 5 includes a support column 50, a fourth lead screw 51, a fourth sliding sleeve 52, and a clamping block 53. Two support columns 50 are arranged on both sides of the printing line 6. The two ends of the fourth lead screw 51 are respectively connected to the support column 50 through a fixed seat. The two fourth sliding sleeves 52 move along the fourth lead screw 51. The clamping block 53 is connected to the fourth sliding sleeve 52 and the guide rail.

[0047] Specifically, the sliding mechanism 5, corresponding to the clamping mechanism 3, is arranged on both sides of the adjusting seat 10 to provide support and positioning during the printing process, ensuring that the product maintains a stable position during printing. The support column 50, arranged on both sides of the printing line 6, provides a stable foundation for the fourth lead screw 51. The fourth lead screw 51 is threadedly connected to the fourth sliding sleeve 52, driving the fourth sliding sleeve 52 to move along its axial direction, thereby adjusting the position of the clamping block 53. The fourth lead screw 51 is also a bidirectional lead screw; the two sliding sleeves rapidly reduce and expand the distance between them under the drive of the lead screw's rotation, achieving precise clamping and positioning of the product. The clamping block 53 and the fourth sliding sleeve 52 are fixedly connected, and the clamping block 53 and the guide rail are fixed by bolts, clips, etc., which can drive the guide rail to move.

[0048] By moving the clamping block 53 and the guide block 21 together, the guide rail can move smoothly and avoid tilting, thus achieving rapid clamping and positioning of the product. It can also ensure that the guide rail applies uniform pressure to the product and avoid uneven force on the product.

[0049] In some embodiments, the guide block 21 extends along the Z-axis and abuts against the guide rail, the guide rail extends along the X-axis and the height of the guide rail in the Z-axis direction is less than or equal to the height of the upper edge of the guide block 21.

[0050] Specifically, the guide block 21 extends along the z-axis and abuts against the side of the guide rail, ensuring more stable force distribution on the guide rail and effective clamping. The upper edge of the guide block 21 connects to the third sliding sleeve 23. The position of the top of the guide rail is lower than the height of the upper edge of the guide block 21, ensuring that the guide block 21 blocks the guide rail and prevents collision damage between the guide rail and the third sliding sleeve 23. It also prevents the product from being unable to enter the clamping area properly due to the guide rail being too high. The guide rail extends along the x-axis, providing lateral support and guidance for the product.

[0051] Optionally, one or both ends of the guide rail can be provided with inclined sections. The inclined sections are tilted away from the product and guide the product to gradually enter the clamping area of ​​the guide rail and straighten it, ensuring that the extension direction of the product coincides with the X-axis direction.

[0052] In some embodiments, a pressure sensor is also included, which is arranged on the pressure roller 30 to detect the pressure of the pressure roller 30 on the product to be printed.

[0053] Specifically, a pressure sensor is mounted on the clamping roller 30, directly contacting the product to be printed. This arrangement allows the pressure sensor to monitor the pressure applied to the product by the clamping roller 30 in real time, ensuring that the magnitude and uniformity of the clamping force meet the requirements of the printing process. Real-time pressure monitoring prevents product damage or printing failure caused by excessive or insufficient pressure from the clamping roller 30, improving printing quality and product yield. The position of the clamping roller 30 is adjusted according to the pressure level to protect the product.

[0054] In some embodiments, a buffer structure is also included, which includes a plurality of elastic elements. One end of the elastic element is connected to the lifting frame 310, and the other end is connected to the pressure wheel 30. The elastic elements and the pressure wheel 30 correspond one-to-one.

[0055] Specifically, each pressure roller 30 is connected to the lifting frame 310 via an elastic element to achieve a buffering function. The elastic element can be a spring, airbag, rubber pad, etc. It provides cushioning and shock absorption; when the pressure roller 30 contacts the product to be printed, the elastic element absorbs some of the impact force, reducing the hard pressure exerted by the pressure roller 30 on the product, thus protecting it from damage. Simultaneously, the elastic element can also adjust the clamping force to a certain extent, ensuring the uniformity of the clamping force. The arrangement of the elastic elements corresponding to the pressure rollers 30 allows each pressure roller 30 to independently obtain a buffering effect, ensuring uniform pressure application.
