[0019] It is worth noting that the servo module positioning wheel moving mechanism 110 and the positioning correction wheel 111 are both provided with six groups, and the middle correction wheel 111 is arranged on the servo module positioning wheel moving mechanism 110 through a lifting cylinder 112 .

[0020] It is worth noting that the printing head moving mechanism 2 includes a moving frame 21, the bottom of the moving frame 21 is fixed to the moving mechanism skeleton 23 through two sets of X-axis slider rail mechanisms 22, the bottom of the moving frame 21 is also connected to the X-axis handwheel 25 through the X-axis screw nut 24, and two sets of Y-axis slider rail mechanisms 26 are arranged on the top of the moving frame 21. The printing head mechanism 3 is arranged on the Y-axis slider rail mechanism 26, and the Y-axis slider rail mechanism 26 is connected to the Y-axis handwheel 28 through the Y-axis screw nut 27. Position displays are arranged at both the X-axis handwheel 25 and the Y-axis handwheel 28.

[0021] In addition, the printing head mechanism 3 is provided with a Z slide rail 31 and a screw nut handwheel adjustment mechanism 32 arranged parallel to the Z slide rail 31, the screw nut handwheel adjustment mechanism 32 has a digital position display, a scale and a locking mechanism, the A cylinder 33 is arranged parallel to the Z slide rail 31, the B cylinder 34 and the C cylinder 35 are connected to the LOGO printing screen fixing seat 36, the LOGO printing screen fixing seat 36 is provided with a LOGO printing screen 37, the C cylinder 35 is installed vertically, the piston rod head of the C cylinder 35 is fixed with a scraper 38, the B cylinder 34 is installed horizontally, and the B cylinder 34 pushes the C cylinder and the scraper to move horizontally.

[0022] The positioning belt conveyor of this specific embodiment is composed of four conveyor belts. The spacing between the two inner conveyor belts is fixed. The fixed seats of the two outer conveyor belts are fixed on the conveyor frame through the linear slider rail mechanism. The bottom fixed seats of the two outer conveyor belts are fixed with nuts, and the nuts of the left and right conveyors are one right-handed and the other left-handed. The nuts and screw rods are matched. The handwheel rotation and locking handle are installed on the outside. By rotating the handwheel, the belt conveyors on both sides can be moved to the center or both sides at the same distance at the same time, which is used to adjust the spacing of the four conveyor belts to adapt to products of different sizes. The four conveyor belts are driven by a motor to rotate on the same drive shaft. The drive shaft has splines, and the belt conveyor drive wheel has spline holes. When the belt conveyors on both sides are adjusted to different positions, power transmission can be achieved. The base belt of the belt is a synchronous belt, which can ensure that the speeds of the four belts are exactly the same, and ensure that the product will not have additional posture changes due to the speed difference of the belts during the conveying process. The surface of the belt is also covered with a layer of non-metallic material with moderate friction and no marks on the product surface. There is enough friction to complete the input and output of the product. At the same time, when the product moves relative to the belt during the product positioning process, the friction resistance is not too large and no marks are left on the product surface. Figure 4 As shown, there are four belt conveyors. The maximum and minimum size range of the existing products can be achieved with four belts. When the maximum and minimum size of the product changes or different numbers of belt conveyors are expected to support the product, in addition to adjusting the center distance of the outer belt conveyors, the number of belt conveyors can be changed by design to adapt to products of different sizes. Six sets of product positioning correction wheels are fixed on the conveyor frame. Each positioning wheel is driven by a set of servo linear modules and can move a certain distance in a straight line. The correction wheel is fixed by the waist hole fixing block fixed on the slider of the linear module. The position of the positioning wheel can be manually adjusted when necessary. The waist hole attachment has a ruler to record the relative position of the positioning wheel after adjustment. The two sets of correction wheels in the middle are installed with lifting cylinders. When the product is input and output from the belt conveyor, the cylinder rod retracts to make the correction wheel lower than the belt conveying surface, ensuring that the product can be smoothly input and output without colliding with the correction wheel. When the product is positioned, the cylinder rod extends to make the upper edge of the correction wheel higher than the belt conveying surface and the lower edge lower than the conveying surface. The six correction wheels move to the center according to the set sequence and position to complete the correction and positioning of the product posture.

[0023] The printing head moving mechanism of this specific embodiment is used to fix and adjust the printing head mechanism. This mechanism mainly realizes movement in two directions, along the belt conveyor direction (X direction) and perpendicular to the belt conveying direction (Y direction). The bottom of the moving frame is fixed to the skeleton through two sets of slider rail mechanisms. There are nuts at the bottom of the moving frame. The moving frame is allowed to achieve movement adjustment and locking in the X direction through the screw nut mechanism. A handwheel and a position indicator are fixed to the head of the screw, and the position is adjusted manually. Two sets of slide rails are fixed to the top of the moving frame. The printing head mechanism is fixed to the moving frame through two sets of slider rail mechanisms. The printing head mechanism has nuts. The printing head mechanism is allowed to achieve movement adjustment and locking in the Y direction through the screw nut mechanism. A handwheel and a position indicator are fixed to the head of the screw, and the position is adjusted manually.

[0024] The printing head mechanism of this specific embodiment is fixed on the printing head moving mechanism. The printing head mechanism is fixed with a Z slide rail in the up and down direction, and a screw nut handwheel adjustment mechanism parallel to the Z slide rail, with a digital position display, a ruler and a locking mechanism, which can adjust the height of the printing head in the Z direction. The A cylinder is parallel to the Z slide rail. When the piston rod is extended, the printing head is at the working height, close to the roller conveying surface. When the piston rod is retracted, the printing head is located at a high place, which is convenient for replacing or maintaining the printing screen. The B cylinder and the C cylinder are fixed together with the LOGO printing screen. The printing screen can be rotated and locked horizontally parallel to the roller conveying surface to change the angle of the printing pattern. The printing screen has a horizontal guide groove and can be inserted into the printing screen fixing seat. There is a locking mechanism on the printing screen fixing seat, which can realize the rapid replacement, positioning and locking of screens with the same shape but different patterns. The C cylinder is installed vertically, and a scraper is fixed on the head of the piston rod. When the piston is extended, the scraper is pressed downward to make the printing screen protrude downward and contact the product surface. The B cylinder is installed horizontally, which can push the C cylinder and the scraper to move horizontally. When the screen contacts the surface of the product, the B cylinder is activated to push or pull the scraper, and the ink is printed on the surface of the product through the printing screen. The printing head can be moved to any position of the product in the working area through the X and Y slide rails, and the Z slide rail can be used to change the different heights of the printing screen to the conveying surface of the roller machine to adapt to products of different thicknesses. The angle of the printing pattern can be adjusted by rotating the horizontal angle of the printing screen, which can adapt to the printing of patterns at various angles.

[0025] The working principle of this specific implementation method: Products are input and output through belt conveyors. There are 4 belt conveyors, the positions of the 2 middle ones are fixed, and the spacing of the 2 outer ones can be adjusted and locked manually through hand wheels according to the size of the product. When the product size is small, the center distance of the belt conveyors on both sides is adjusted to be smaller. When the product size is larger, the center distance of the belt conveyors on both sides is adjusted to be larger so that the product can be fully supported to avoid damage during transportation and positioning correction. The product is input to the set position and stops. The 2 sets of positioning wheel cylinders in the middle are lifted, and the positioning wheels are raised from the bottom of the conveying surface to the correction height. Together with the surrounding correction wheels, a total of 6 sets of correction wheels are driven by the servo linear module and move to the center position according to the set program. The product posture is positioned and corrected by the positioning wheels. The piston rod of the C cylinder in the printing head mechanism extends, and the scraper makes the LOGO printing screen contact with the upper surface of the product. Under the push of the piston rod of the B cylinder, the scraper moves horizontally by the distance of a cylinder stroke to complete the printing of the LOGO in the rectangular area of ​​the scraper moving track. After the printing is completed, the piston of the C cylinder retracts to make the scraper rise, so that the LOGO printing screen is out of contact with the upper surface of the product. The B cylinder can complete the printing action in both the extension stroke and the retraction stroke. The A cylinder retracts, and the screen can be quickly raised a certain distance when the printing screen needs to be replaced, which is convenient for replacement. There are grooves on both sides of the screen frame, and screens with different patterns are fixed in the screen frame with the same shape. When the printed pattern needs to be changed, the screen frame with the screen can be replaced. The screen frame can be rotated horizontally in the screen fixing seat to adjust the angle. The rotation angle can be recorded and adjusted by the scale on the screen fixing seat. The rotation angle can be quickly released and locked by the locking mechanism on the screen fixing seat to change the angle of the printed pattern on the product. The Z adjustment hand wheel can fine-tune the vertical distance from the printing mechanism to the belt conveyor surface, and can be adjusted and locked in height when producing products of different thicknesses. The X and Y direction adjustment hand wheels of the printing head can change the position of the printed pattern on the product in the X and Y directions. After the positioning correction is completed, the correction wheels retreat to the initial position in all directions, and the two sets of correction wheel cylinders in the middle retract to lower the positioning wheels to the bottom of the belt conveyor surface and return to the initial position. The belt conveyor outputs the product, completing a cycle.

[0026] The conveyor of this specific embodiment is composed of multiple belts, and the spacing between the outer belts can be adjusted to accommodate products of different sizes. There are 6 sets of correction wheels, and the middle correction wheel needs to have a lifting function. According to the different shapes of products, as well as the different definitions of product input and printing posture, the number and distribution of correction wheels need to be changed accordingly and designed differently. The printing head can reach any position in the working area by adjusting in the XY direction, and can adapt to the production of products of different thicknesses by adjusting in the Z direction. The angle of the printed pattern on the product can be adjusted by adjusting the horizontal angle of the printing head. The printing screen can be quickly replaced. It can adapt to the production of a variety of different products, and the changeover is fast and flexible. The positioning wheel mechanism is currently adjusted by the servo module, and the X, Y, and Z adjustment mechanisms of the printing head are manually adjusted by handwheels. The manual adjustment mechanism and the servo adjustment mechanism can be selected according to customer needs.
