DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] As attached Figure 1-2As shown, a paper pulling and positioning device of a hot stamping machine includes a hot stamping platform 1, a paper pressing assembly 4 and a movable mounting seat 5; the hot stamping platform 1 is used to support the substrate, and the hot stamping platform 1 is loaded and fed through a suction cup assembly.

In the hot stamping state, the paper pressing drive assembly 6 drives the paper pressing assembly 4 to press the substrate on the hot stamping platform 1; in the loading state, the paper pressing drive assembly 6 drives the paper pressing assembly 4 to enter the avoidance space. Space 2; specifically, the paper pressing assembly 4 includes a guide bar 42 and a pressing piece 41, the pressing piece 41 is laterally adjusted and arranged on the guide bar 42, the guide bar 42 has a transverse guide groove 421, the transverse guide groove 421 is used to guide the movement of the pressing piece 41, a plurality of pressing pieces 41 can be arranged, and the pressing pieces 41 can be adapted to printing materials of different specifications by moving in the transverse guide groove 421, in addition, the pressing piece 41 has a positioning hole 411, the positioning hole 411 is in the shape of an elongated strip, the positioning hole 411 is fixed in the transverse guide groove 421 with a positioning bolt, and the front and rear position of the pressing piece 41 can be adjusted by adjusting the position of the positioning screw in the elongated positioning hole 411 to further adapt to printing materials of more different specifications. The movable mounting seat 5 is transmission-connected with an oblique driving component 51 that drives the movable mounting seat 5 to move obliquely. The oblique driving component 51 is a cylinder. The paper pressing assembly 4 is arranged on the movable mounting seat 5. The paper pressing assembly 4 is installed on the movable mounting seat 5 through the paper pressing driving assembly 6. The movable mounting seat 5 is fixedly arranged on the driving rod of the oblique driving component 51. The oblique driving component 51 is fixedly arranged on the base 7. In addition, in order to ensure the stable movement of the movable mounting seat 5, a guide rail is arranged on the base 7, and the movable mounting seat 5 is slidably arranged on the guide rail. The oblique driving component 51 drives the paper pressing assembly 4 to cooperate with the front stop gauge and the side stop gauge 3 to position the substrate, that is, the paper pressing driving component 6 drives the pressing piece 41 of the paper pressing assembly 4 to press the substrate, and the oblique driving component 51 drives the paper pressing assembly 4 to move obliquely, wherein the front stop gauge is arranged on the side of the oblique moving direction of the substrate.

[0022] There are many ways for the paper pressing drive assembly 6 to drive the paper pressing assembly 4 to move. For example, the paper pressing drive assembly 6 includes a swing arm seat 61 and a swinging power source 63 that drives the swing arm seat 61 to move. The swinging power source 63 can be a rotary cylinder or a motor. The swinging power source 63 is fixedly connected to one end of the swing arm 62, and the other end of the swing arm 62 is hinged to the swing arm seat 61. The paper pressing assembly 4 is arranged on the swing arm seat 61, and the guide bar 42 of the paper pressing assembly 4 is installed on the swing arm seat 61.

Alternatively, the paper pressing drive assembly 6 includes a drive seat, a lifting drive component and a transverse drive component, the lifting drive component is fixedly arranged on the base 7, the lifting drive component is transmission-connected with the drive seat, the lifting drive component drives the drive seat to move up and down, the transverse drive component is arranged on the drive seat, the transverse drive component is transmission-connected with the paper pressing assembly 4, the transverse drive component is connected with the guide bar 42, the lifting drive component and the transverse drive component cooperate to drive the press sheet 41 into the notch 31 of the side stop 3 to press the paper. The swing paper pressing method is preferred because the swing paper pressing method has lower cost and simpler structure.

[0023] There are many types of pressing sheet 41, which may be a stainless steel sheet or a spring sheet. In order to automatically adjust the pressure according to the thickness of the substrate and ensure that the substrate is flat during hot stamping, the pressing sheet 41 is preferably a spring sheet. Example 1

[0024] According to the specifications of the substrate, the plurality of pressing pieces 41 are adjusted laterally through the transverse guide grooves 421 , and the positioning bolts fix the positions of the pressing pieces 41 through the positioning holes 411 .

[0025] As attached Figure 3 As shown, the initial position of the pressing sheet 41 is in the avoidance space 2. After the substrate is placed on the hot stamping platform 1, the swing power source 63 drives the pressing sheet 41 to swing upward, pressing the substrate through the notch 31, and the oblique pull driving component 51 drives the substrate pressed by the pressing sheet 41 to move obliquely, and the adjacent two sides of the substrate contact the front stop gauge and the side stop gauge 3 respectively, so as to achieve accurate correction of the position of the substrate. During the hot stamping process, the pressing sheet 41 continuously presses the substrate to ensure the hot stamping quality and improve the yield rate. After the hot stamping is completed, the pressing sheet 41 returns to its original position, waiting for the subsequent substrate to enter, and repeats the above actions. Example 2

[0026] The position adjustment method of the pressing piece 41 is the same as that of the first embodiment, and the difference lies in the action of the pressing piece 41.

[0027] As attached Figure 4As shown, after the substrate is placed on the hot stamping platform 1, the lifting drive component on the movable mounting seat 5 drives the driving seat to rise, and the lateral drive component on the driving seat drives the pressing piece 41 on the guide strip 42 to enter the notch 31. The lifting drive component drives the pressing piece 41 to move downward to press the substrate, and the oblique pull drive component 51 drives the movable mounting seat 5 to drive the pressing piece 41 to move obliquely, and the substrate moves accordingly, so that the adjacent two sides of the substrate are respectively in contact with the front stop gauge and the side stop gauge 3, so as to achieve accurate correction of the position of the substrate. During the hot stamping process, the pressing piece 41 continuously presses the substrate to ensure the hot stamping quality and improve the yield. After the hot stamping is completed, the pressing piece 41 returns to its position, waiting for the subsequent substrate to enter, and repeats the above actions.
