[0002] In the prior art, the utility model with application number 202221664445.6 discloses a printing machine with a positioning mechanism. In order to observe with the naked eye whether the printing plate is aligned with the printed product and press the printing plate down to the top of the printed product, there are visual errors when observing with the naked eye, and it is easy for the printing plate and the printed product to be slightly misaligned, affecting the qualified rate of the printed products. By setting a printing positioning mechanism and a photoelectric sensor receiver, the photoelectric sensor receiver slides with the carrier relative to the translation shell, and the installation position of the photoelectric sensor transmitter on the printing positioning mechanism remains fixed. When the photoelectric sensor receiver moves to the bottom of the photoelectric sensor transmitter, the circuit of the lifting cylinder is connected, and the lifting cylinder drives the fixed printing plate to contact the printed product fixed on the carrier, and prints the printed product, thereby avoiding the misalignment between the printing plate and the printed product during printing, and improving the qualified efficiency of the printed products after printing.

[0003] Similar to the above application, there are still some deficiencies:

[0004] During the calibration process of printed products, only left and right adjustments can be made, and the front and rear ends of the printed products cannot be adjusted together, which affects the calibration accuracy. In addition, the calibration process requires control through a complex control system, which increases the production and use costs.

[0032] Example 1

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment provides a printing mechanism with positioning and calibration functions, including a base 1, a cam frame 101 vertically fixed between two sides of the top of the base 1, a mounting plate 102 located at the bottom of the cam frame 101, a printing plate 103 mounted on the bottom of the mounting plate 102, and a cylinder 104 for controlling the vertical lifting of the mounting plate 102;

[0034] Side panels 2 are slidably provided on both sides of the top of the machine base 1. The two sets of side panels 2 are parallel to each other. The outer sides of the side panels 2 are provided with horizontal movement mechanisms 3 for controlling the side panels 2 to move toward each other. End panels 4 are slidably provided on both ends of the top of the machine base 1. The outer sides of the end panels 4 are provided with longitudinal movement mechanisms 5 for controlling the end panels 4 to move toward each other.

[0035] During the printing process, a square printing material of fixed specifications is placed on the top of the machine base 1 and located between the end plate 4 and the side plate 2. Then the cylinder 104 is started to control the printing plate 103 to move vertically downward. When the printing plate 103 moves vertically, the two sets of side plates 2 are simultaneously controlled to move toward each other through the horizontal moving mechanism 3. When the side plates 2 move toward each other, the end plates 4 are driven to move toward each other through the longitudinal moving mechanism 5. The side plates 2 and the end plates 4 simultaneously squeeze and fit the sides of the printing material, and automatically correct the printing material. Finally, the surface of the printing material is printed.

[0036] Example 2

[0037] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0038] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the lateral movement mechanism 3 includes an inverted L-shaped rod 301, a first inclined surface 302, a cross bar 303, a second inclined surface 304 and a return spring 305, the inverted L-shaped rod 301 is symmetrically fixed on both sides of the inverted L-shaped rod 301, the bottom of the inner side of the inverted L-shaped rod 301 is provided with a first inclined surface 302, the outer side of the side plate 2 is vertically fixed with a cross bar 303, the top of the cross bar 303 away from the side plate 2 is provided with a second inclined surface 304 that cooperates with the first inclined surface 302, and a return spring 305 is provided between the side plate 2 and the inner side of the cam frame 101.

[0039] When the cylinder 104 is started, it drives the mounting plate 102 to move downward, and the mounting plate 102 drives the inverted L-shaped rod 301 to move vertically downward. During the downward movement of the inverted L-shaped rod 301, the first inclined surface 302 and the second inclined surface 304 fit together. As the inverted L-shaped rod 301 continues to move downward, the two sets of side plates 2 are pushed toward each other to perform extrusion correction on the printing material.

[0040] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, both ends of the outer side of the side panel 2 are fixed with sliding rods 306, the sliding rods 306 pass through the inside of the return spring 305, the sliding rods 306 pass through the cam frame 101 and are slidably connected to the cam frame 101.

[0041] The use of the sliding rod 306 can limit the position of the side plate 2 during its sliding, and can also limit the return spring 305.

[0042] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, a ball 307 is evenly mounted on the end surface of the cross bar 303 away from the side plate 2;

[0043] When the first inclined surface 302 is no longer in contact with the second inclined surface 304, the side plate 2 completes the lateral movement, and the correction of the printing material is completed. The cylinder 104 still needs to control the inverted L-shaped rod 301 to move downward a certain distance for printing. When the inverted L-shaped rod 301 continues to move downward, the ball 307 on the end face of the cross bar 303 will contact the inner side of the inverted L-shaped rod 301, reducing the resistance of the inverted L-shaped rod 301 when it moves downward.

[0044] like Figure 1 As shown, as a preferred embodiment, on the basis of the above-mentioned embodiment, further, a guide groove 308 is vertically opened on the inner side of the U-shaped frame 101, and the inverted L-shaped rod 301 is located inside the guide groove 308.

[0045] The guide groove 308 can not only limit the inverted L-shaped rod 301 , but also ensure the vertical movement of the printing plate 103 .

[0046] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, the longitudinal moving mechanism 5 further includes a push rod 501 and a guide member, the push rod 501 is hingedly installed on the outer end of the end plate 4, and the end of the push rod 501 away from the end plate 4 is hinged to the end of the side plate 2 respectively.

[0047] When the two sets of side plates 2 move toward each other, the push rod 501 can be used to control the end plate 4 to move toward the printing substrate, thereby performing position limiting correction on both ends of the printing substrate.

[0048] like Figure 4As shown, as a preferred embodiment, on the basis of the above method, the guide member further includes a slide groove 502 and a slider 503. The slide groove 502 is opened at the middle position of the two ends of the top of the base 1 along the width direction of the base 1. The slider 503 is slidably installed inside the slide groove 502. The slider 503 is fixedly connected to the end plate 4.

[0049] During the movement of the end plate 4 , the slider 503 is driven to move inside the slide groove 502 , ensuring that the end plate 4 can only move in a straight line, thereby ensuring the fitting effect between the end plate 4 and the end surface of the substrate.

[0050] Example 3

[0051] The solutions in Example 1 and Example 2 are further introduced below in conjunction with specific working methods, as described below:

[0052] During the printing process, a square substrate of fixed specifications is placed on the top of the machine base 1 and located between the end plate 4 and the side plate 2. Then, the cylinder 104 is started to control the mounting plate 102 to move vertically downward. The mounting plate 102 will drive the inverted L-shaped rod 301 to move vertically downward. During the downward movement of the inverted L-shaped rod 301, the first inclined surface 302 and the second inclined surface 304 fit together. As the inverted L-shaped rod 301 continues to move downward, the two sets of side plates 2 are pushed toward each other to perform extrusion correction on the substrate. When the two sets of side plates 2 move toward each other, the end plate 4 can be controlled by the push rod 501 to move toward the substrate. The two ends of the printing material are moved in a limited manner. After the side plates 2 and the end plates 4 correct and position the printing material, the first inclined surface 302 and the second inclined surface 304 are no longer in contact, and the cylinder 104 still needs to control the inverted L-shaped rod 301 to move downward a certain distance for printing. When the inverted L-shaped rod 301 continues to move downward, it will be inserted into the inside of the machine base 1, and then the printing is completed. When the printing is completed, when the cylinder 104 is reset, the cross bar 303 loses the extrusion force, and the reset spring 305 controls the reset of the cross bar 303. The side plates 2 and the end plates 4 are reset at the same time, and the positioning state of the printing material is released.

[0053] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
