DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0041] First, combine Figures 1 to 9 A pad printing machine according to an embodiment of the present invention is described, which is used for printing patterns on materials.

[0042] like Figures 1 to 6 As shown, a pad printing machine according to an embodiment of the present invention comprises: a conveying component, a pad printing component, a cleaning component, a heating component and a blanking component;

[0043] The conveying component is used to move the material to the pad printing component, heating component and unloading component;

[0044] The pad printing components include: ink cup and pad printing head;

[0045] The ink cup is used to produce the pattern to be printed, and the pad printing head is used to print the pattern onto the material.

[0046] The cleaning components include: a cleaning cylinder, a cleaning plate, a cleaning film and a film rolling mechanism;

[0047] The cleaning film is placed on the cleaning plate. The cleaning cylinder drives the cleaning plate to move so that the cleaning film can clean the pad printing head. The film rolling mechanism is used to replace the cleaning film used to clean the pad printing head.

[0048] The heating component is used to fix the printed pattern to the material;

[0049] The unloading component is used to remove materials from the conveying component.

[0050] The material is placed on the conveying component, which conveys the material to the pad printing component, cleaning component, heating component and unloading component in sequence. The oil cup of the pad printing component produces the pattern that needs to be printed on the material, and the pad printing head prints the pattern on the material. After the pad printing head has been used for a period of time, the cleaning plate is driven to move by the cleaning cylinder, and the cleaning film is moved to a position suitable for cleaning the pad printing head. The pad printing head is cleaned by contacting the cleaning film with the pad printing head. The film rolling mechanism replaces the used cleaning film to facilitate the next cleaning of the pad printing head. After printing, the material is heated by the heating component to fix the printed pattern on the material. After heating is completed, the material is removed from the conveying component by the unloading component for subsequent collection.

[0051] like Figure 4 As shown, the pad printing assembly includes: a linear mechanism, a connecting arm, and a pad printing plate;

[0052] The linear mechanism is used to drive the connecting arm to move. One end of the connecting arm is connected to the linear mechanism and the other end is connected to the oil cup. The pad printing plate is arranged below the oil cup, and the pattern produced by the oil cup is placed on the pad printing plate.

[0053] The pad printing assembly also includes: a vertical mechanism, which is arranged on the output part of the linear mechanism, the output end of the vertical mechanism is connected to the pad printing head, the vertical mechanism drives the pad printing head to move in the vertical direction, and the oil cup and the pad printing head move synchronously under the drive of the linear mechanism.

[0054] The ink cup places the pattern to be printed on the pad printing plate. The linear mechanism drives the connecting arm and the vertical mechanism to move synchronously, so that the ink cup moves away from the pattern on the pad printing plate and the pad printing head is moved to the top of the pattern on the pad printing plate. The vertical mechanism drives the pad printing head to move so that the pattern on the pad printing plate adheres to the pad printing head. The linear mechanism drives the vertical mechanism to move and moves the pad printing head to the top of the material to be printed. The vertical mechanism drives the pad printing head to descend and the pad printing head prints the pattern onto the material.

[0055] The linear mechanism and the vertical mechanism in this embodiment are both linear modules, which form a cross module. The linear mechanism and the vertical mechanism cooperate to drive the pad printing head to move, so that the pad printing head can perform rapid printing.

[0056] like Figure 4~Figure 5 As shown, the pad printing assembly includes: a limiting mechanism, which is arranged on the linear mechanism and is used to limit the moving distance of the connecting arm and the vertical mechanism on the linear mechanism. The moving distance is related to the length of the pad printing plate.

[0057] The limiting mechanism includes: two oppositely arranged baffles, telescopic rods are provided on the baffles, and top plugs are provided at opposite ends of the two telescopic rods. The distance between the two top plugs is related to the length of the pad printing plate.

[0058] The limit mechanism can limit the stroke of the linear mechanism to avoid derailment. The limit mechanism makes the stroke of the linear mechanism the same as the length of the pad printing plate, preventing the linear mechanism from moving the oil cup from above the pad printing plate, causing the liquid in the oil cup to drip into the pad printing machine and pollute the environment inside the pad printing machine.

[0059] The stroke of the linear mechanism can be adjusted by adjusting the length of the telescopic rod, so that the linear mechanism can be suitable for pads and oil cups of different lengths. The top plug can prevent the limit mechanism from colliding with the vertical mechanism and causing damage.

[0060] like Figure 6 As shown, the cleaning assembly includes: a cleaning slide rail;

[0061] The cleaning plate is slidably arranged on the cleaning slide rail, the output end of the cleaning cylinder is connected to the cleaning plate, and the cleaning cylinder is used to drive the cleaning plate to move below the pad printing head.

[0062] The cleaning cylinder drives the cleaning plate to slide on the cleaning slide rail, which can move the cleaning plate to the bottom of the pad printing head. The vertical mechanism drives the pad printing head to descend, so that the pad printing head contacts the cleaning film on the cleaning plate, and the cleaning film cleans the pad printing head. After the pad printing head is cleaned, the cleaning cylinder drives the cleaning plate to slide on the cleaning slide rail, and moves the cleaning plate away from under the pad printing head to prevent the cleaning plate from interfering with the pad printing head on the material.

[0063] like Figure 6 As shown, the film rolling mechanism includes: a film rolling motor, a driving wheel, a driven wheel, a first adjusting wheel and a second adjusting wheel;

[0064] The film winding motor is used to drive the driving wheel to rotate. The cleaning film is located on the driven wheel. The cleaning film passes through the first adjusting wheel, the lower surface of the cleaning plate, the upper surface of the cleaning plate and the second adjusting wheel in sequence. The starting end of the cleaning film is placed on the driving wheel.

[0065] The film rolling motor can keep the cleaning film at a certain tension at all times. When the cleaning cylinder drives the cleaning plate to move to the bottom of the pad printing head, the cleaning plate will pull the cleaning film to rotate the driven wheel. When the cleaning cylinder drives the cleaning plate to reset, the tension of the cleaning film will decrease. The film rolling motor drives the driving wheel to rotate, and the used cleaning film is partially rolled onto the driving wheel to maintain the tension of the cleaning film.

[0066] like Figure 7 As shown, the heating assembly includes: a heating cover and a heating tube;

[0067] The heating tube is arranged in the heating cover and is used to heat the material so as to fix the printed pattern on the material.

[0068] The heating tube heats the surface of the material and quickly fixes the printed pattern to the material. The heating cover can prevent the heat generated by the heating tube from dissipating and improve the heating efficiency.

[0069] like Figure 8 As shown, the blanking assembly includes: a material receiving moving mechanism, a material receiving plate and a vacuum suction cup;

[0070] The receiving plate is arranged on the output end of the receiving moving mechanism, the vacuum suction cup is arranged on the receiving plate, the vacuum suction cup is used to absorb the material, and the receiving moving mechanism is used to move the vacuum suction cup in a vertical plane.

[0071] In this embodiment, the material receiving moving mechanism is a cross module. The material receiving moving mechanism moves the material receiving plate to the top of the material, and then drives the material receiving plate to descend. The vacuum suction cup absorbs the material on the feeding component and removes the material from the conveying component.

[0072] like Figure 9 As shown, the conveying assembly includes: a conveying motor, a conveying guide rail, a conveying plate and a conveying mold;

[0073] The conveying plate is slidably arranged on the conveying guide rail, the conveying motor is used to drive the conveying plate to move on the conveying guide rail, the conveying mold is arranged on the conveying plate, and the conveying mold is used to position the material.

[0074] The conveying motor drives the conveying plate to move on the conveying guide rail, so that the conveying plate passes through the pad printing component, heating component and unloading component in sequence. The conveying mold is set according to the shape of the material, which can position the material and prevent the material from moving during printing.

[0075] Above, refer to Figures 1 to 9 A pad printing machine according to an embodiment of the utility model is described. In this embodiment, a cleaning plate is driven to move by a cleaning cylinder, and the cleaning film is moved to a position suitable for cleaning the pad printing head. The pad printing head contacts the cleaning film to clean the pad printing head, thereby avoiding dust accumulation on the pad printing head, affecting the complete lines of the printed pattern, avoiding secondary printing, and improving the production efficiency of the material.
