The handwheel 21 is connected to the linear slide 23 through the screw nut 22. A baffle 24 is fixed on the linear slide 23. The baffle 24 is close to the surface of the roller 12 and is provided with a semicircular notch to avoid the roller.

[0026] It is worth noting that a mechanical position indicator is provided on the screw rod of the hand wheel 21 .

[0027] It is worth noting that the stop mechanism 3 includes a stop cylinder 31, a guide rod 32, a slide groove 33, a handle 34, a locking mechanism 35, a stop wheel 36 and a guide rail 37. The two stop wheels 36 are installed on the guide rail 37 through a stop wheel fixing seat 38. The stop wheel fixing seat 38 can be rotated horizontally and locked. The guide rail 37 is fixed in the slide groove 33. A handle 34 and a locking mechanism 35 are provided at one end of the guide rail 37. The slide groove 33 is connected to the stop cylinder 31 through two sets of guide rods 32.

[0028] It is worth noting that a scale is provided on the guide rail 37 and an angle scale is provided on the blocking wheel fixing seat 38 .

[0029] It is worth noting that two X slide rails 41 are arranged at the bottom of the printing mechanism 4, which are parallel to the conveying direction of the roller conveyor, a moving seat 42 is arranged on the X slide rail 41, a Y slide rail 43 is arranged on the moving seat 42, a Z slide rail 44 is arranged on the Y slide rail 43, an A cylinder 45 is arranged parallel to the Z slide rail 44, a B cylinder 46 and a C cylinder 47 are fixed to a LOGO printing screen fixing seat 410, a LOGO printing screen 48 is arranged on the LOGO printing screen fixing seat 410, the C cylinder 47 is installed vertically, a scraper 49 is fixed to the head of the piston rod of the C cylinder 47, and the B cylinder is installed horizontally, and the B cylinder pushes the C cylinder 47 to move horizontally.

[0030] In addition, the printing screen 48 is provided with a horizontal guide groove, and the printing screen fixing seat 410 is provided with a printing screen locking mechanism and a horizontal angle adjustment mechanism.

[0031] From the perspective of product conveying direction, this specific implementation method is composed of a roller conveyor 1, a guide mechanism 2, a stop mechanism 3 and a printing mechanism 4. The roller conveyor is driven by a motor, and the roller is a rubber-coated surface, which will not cause defects such as marks and scratches on the product surface. Customers who have particularly high requirements for product surface quality can also choose to install a torque limiting clutch on the roller in the positioning area. After the product is positioned, the product is fixed by the baffles on both sides of the guide mechanism 2 and the stop mechanism 3 at the tail. The roller drive device is still driving the roller to rotate slowly. It is only necessary to set the value of the torque limiting clutch to be less than the friction between the roller and the product. At this time, the roller under the product will stop rotating because the friction is greater than the driving force of the clutch. The roller drive device is still rotating slowly without stopping. This can avoid relative movement between the roller and the product surface, further reducing the probability of marks and scratches. The roller drive device does not stop, which can shorten the cycle and improve production efficiency.

[0032] The guide mechanism of this specific embodiment is manually adjusted by a handwheel, and the baffles on both sides are each adjusted in position by a corresponding handwheel. The handwheel can be manually locked, and the handwheel screw is provided with a mechanical position display, which can display the position size parameters of the baffle. The baffle is close to the surface of the roller, and a semicircular notch is made to avoid the roller, which can prevent the product from getting stuck in the gap between the baffle and the roller. The left and right baffles are fixed on two linear slide rails at the bottom. By shaking the handwheel, the baffle can be driven to move toward the center or outside of the roller conveyor by the screw nut mechanism. The distance between the baffles on both sides can be changed by adjusting the two handwheels. The baffles on both sides cooperate with the two sets of positioning wheels of the stop mechanism 3 located at the tail of the baffle and the roller that rotates forward slowly to achieve rapid positioning of the product position.

[0033] The stop mechanism 3 of this specific embodiment is fixed below the roller conveyor 1 and is located at the tail of the guide mechanism 2. There are two adjustable stop wheels on the stop mechanism. The stop wheels are installed on the guide rail, and a ruler is fixed along the guide rail. The two sets of stop wheels can be adjusted to a suitable position along the guide rail and manually locked. In addition to adjusting left and right along the guide rail direction, the two sets of stop wheels can also be adjusted perpendicular to the guide rail direction by rotating the horizontal angle of the roller fixing seat, that is, front and back adjustment along the conveying direction of the roller conveyor. The entire guide rail mechanism with two sets of stop wheel mechanisms is fixed in the slide groove, and one end of the guide rail mechanism is provided with a handle and a locking mechanism. When the stop mechanism needs to be adjusted, the locking mechanism is first released, and then the handle is pulled to pull the entire guide rail mechanism out along the slide groove, so that it is convenient to manually adjust the left and right and front and back positions of the two sets of stop wheel mechanisms by relying on the ruler. The two sets of adjusted stop wheels cooperate with the two guide plates (baffles) of the guide mechanism 2 to achieve rapid and accurate positioning of the product by controllable blocking of the product during the roller conveying process. The guide rail mechanism and the bottom slide are driven by the cylinder at the bottom for lifting and lowering. There are two sets of guide rods on each side of the cylinder to ensure the smooth and stable lifting process of the entire mechanism, and to withstand the thrust of the product contacting the positioning wheel during positioning without deformation, ensuring positioning accuracy. When the positioning and printing actions are completed, the cylinder rod retracts, and the two sets of positioning wheels are lowered below the conveying surface of the roller conveyor, allowing the product to pass through the roller conveyor.

[0034] The printing mechanism of this specific embodiment has two X slide rails at the bottom, which are parallel to the conveying direction of the roller conveyor and are used for adjusting and locking the printing head in the X direction. The moving seat is fixed with a Y slide rail, and a screw nut handwheel adjustment mechanism parallel to the Y slide rail, with a digital position display, a ruler and a locking mechanism, which can adjust the position of the printing head in the Y direction. The moving seat 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. Cylinder A 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 at the changeover height, which is convenient for replacing or maintaining the printing screen. Cylinder B and C cylinders are fixed together with the LOGO printing screen fixing seat. The printing screen fixing seat can be horizontally rotated and locked parallel to the roller conveying surface to change the angle of the printing pattern. The printing screen has a horizontal guide groove, and there is a locking mechanism on the printing screen fixing seat, which can realize the rapid replacement and locking of screens with different patterns. C cylinder is installed vertically, and a scraper is fixed on the piston rod head. When the piston extends, the scraper is pressed downward, so that the printing screen protrudes downward and touches the surface of the product. B cylinder is installed horizontally, which can push C cylinder and scraper to move horizontally. When the screen touches the surface of the product, cylinder B is started 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 adjustment of the printing pattern can be achieved by rotating the horizontal angle of the printing screen fixing seat, which can adapt to the printing of patterns at various angles.

[0035] The roller under the product in the printing area of ​​this specific embodiment can be upgraded to install a torque limiting clutch, which further reduces the probability of surface marks on the product and improves product quality. The roller conveyor generally keeps rotating at a slow speed during printing. When the customer's production cycle is long, you can also choose to stop the roller rotation at this time. There is no need to install a torque limiting clutch, which can also reduce the probability of surface marks on the product. The guide mechanism baffles on both sides constrain the left and right positions of the product, the blocking wheel of the blocking mechanism and the roller rotating forward constrain the front and rear positions and angles of the product, and work together to complete the rapid positioning of the product position. The printing head can reach any position in the working area by adjusting the XY direction, and can adapt to the production of products of different thicknesses by adjusting the Z direction. The angle adjustment of the printed pattern on the product can be achieved by adjusting the horizontal angle of the printing head fixing seat. 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 front and rear two units can be produced in series to further improve production efficiency.
