Wherein, the opposite ends of the connecting piece are fixedly connected with the two slide rails 300 on the side wall close to each other.

[0034] The license plate stamping die frame conveying and cover opening and closing device provided by the application drives the slide rail 300 to move towards or away from the stamping platform 101 on the license plate pressing machine body 100 through the driving assembly 600, and the die frame 200 connected to the slide rail 300 through the guide rod 500 and the license plate in the die frame 200 are placed on or taken out from the stamping platform 101 in the process of movement of the slide rail 300, and since one end of the cover 201 is hinged to the license plate pressing machine body 100 through the connecting rod assembly 202 and the other end is hinged to the die frame 200, the cover 201 is automatically covered on the die frame 200 or opened in the process of placing or taking out the die frame 200 and the license plate in the die frame 200 on or from the stamping platform 101, that is, the application realizes automatic placing or taking out of the license plate on or from the stamping platform 101, and also realizes automatic opening and closing of the cover 201 to facilitate placing or taking out the license plate in or from the die frame 200, avoiding the tedious manual operation and improving the efficiency of license plate pressing.

[0035] In some embodiments, with reference to Figure 1 The connecting rod assembly 202 in the application includes a first connecting rod 2021 and a second connecting rod 2022, specifically, one end of the first connecting rod 2021 is hinged to the license plate pressing machine body 100, and the other end is hinged to one end of the second connecting rod 2022, and the end of the second connecting rod 2022 away from the first connecting rod 2021 is hinged to the cover 201.

[0036] In the above embodiment, when the die frame 200 exits the stamping platform 101, the cover 201 is in an open state, the license plate is placed in the die frame 200, and in the process of gradually moving the die frame 200 towards the stamping platform 101 by the slide rail 300, the die frame 200 pulls the cover 201 hinged thereto to gradually close, and when the die frame 200 gradually exits the stamping platform 101, the first connecting rod 2021 hinged to the license plate pressing machine body 100 and the second connecting rod 2022 hinged to the first connecting rod 2021 pull the cover 201 hinged to the second connecting rod 2022 to take out the pressed license plate from the die frame 200, and the above process realizes automatic opening and closing of the cover 201, avoiding manual opening or closing of the cover 201, thereby improving the efficiency of closing the cover 201.

[0037] In some embodiments, with reference to Figure 2The driving assembly 600 in the application includes a lead screw 601 and a driving motor 602. Specifically, one end of the lead screw 601 is rotationally arranged on the side wall of the license plate pressing machine body 100, and the other end of the lead screw 601 is rotationally arranged and penetrates through the support plate 800 on the operation platform. The connecting piece 700 is threadedly sleeved on the lead screw 601. The driving motor 602 is arranged on the operation platform, and the output shaft of the driving motor 602 is drivingly connected with one end of the lead screw 601 penetrating through the support plate 800 through a transmission member 900.

[0038] In the above embodiment, the driving motor 602 is started, the lead screw 601 connected with the driving motor 602 through the transmission member 900 is driven to rotate by the driving motor 602, and the connecting piece 700 threadedly sleeved on the lead screw 601 is moved along the length direction of the lead screw 601 in the process of rotation of the lead screw 601. Since the connecting piece 700 is fixedly connected with the two slide rails 300, that is, the connecting piece 700 drives the two slide rails 300 to slide along the slide blocks 400 in the process of moving along the length direction of the lead screw 601, so that the mold frame 200 is placed on the stamping platform 101 or withdrawn from the stamping platform 101, and the automatic pushing of the mold frame 200, the cover 201 and the license plate is realized, thereby improving the stamping efficiency of the license plate.

[0039] In some embodiments, with reference to Figure 2 The transmission member 900 in the application includes a first belt pulley 901, a second belt pulley 902 and a synchronous belt 903. Specifically, the first belt pulley 901 is sleeved on the output shaft of the driving motor 602, the second belt pulley 902 is sleeved on one end of the lead screw 601 penetrating through the support plate 800, and the synchronous belt 903 is sleeved on the first belt pulley 901 and the second belt pulley 902.

[0040] In the above embodiment, the driving motor 602 is started, and the driving motor 602 drives the first pulley 901 fixedly sleeved on the output shaft thereof to rotate in the process of operation, and the first pulley 901 drives the second pulley 902 connected therewith through the synchronous belt 903 to rotate synchronously in the process of rotation, and since the second pulley 902 is fixedly sleeved on the lead screw 601, that is, the second pulley 902 drives the lead screw 601 to rotate in the process of rotation, and the lead screw 601 drives the connecting piece 700 threadedly sleeved thereon to move along the length direction of the lead screw 601 in the process of rotation, so as to realize that the slide rails 300 fixedly connected with the connecting piece 700 are close to or away from the stamping platform 101, and further realize the automatic pushing of the die frame 200, the cover 201 and the license plate and the automatic opening and closing of the cover 201, thereby improving the stamping efficiency of the license plate. Compared with the mode that the driving motor 602 directly drives the lead screw 601 to rotate, the synchronous transmission mode of the first pulley 901, the second pulley 902 and the synchronous belt 903 has more accurate transmission ratio, higher transmission efficiency and better stability, and further makes the automatic pushing process of the die frame 200, the cover 201 and the license plate more stable.

[0041] In some embodiments, with reference to Figure 2 The connecting piece 700 in the application includes a connecting plate 701 and a connecting block 702. Specifically, the two ends of the connecting plate 701 are connected to the side walls of the two slide rails 300 that are close to each other and perpendicular to each other, and the top surface of the connecting block 702 is arranged on the lower surface of the connecting plate 701 and is threadedly sleeved on the lead screw 601. The connecting block 702 is provided with a threaded hole matched with the lead screw 601.

[0042] In the above embodiment, in the process of rotation of the lead screw 601, the connecting block 702 threadedly sleeved on the lead screw 601 moves along the length direction of the lead screw 601, and the connecting block 702 drives the connecting plate 701 fixedly connected therewith and the slide rails 300 fixedly connected with the connecting plate 701 to move back and forth in the process of movement, so as to realize the automatic pushing of the die frame 200, the cover 201 and the license plate, thereby improving the stamping efficiency of the license plate.

[0043] In some embodiments, with reference to Figure 2 The top surface of one of the slide rails 300 in the application is provided with a tension spring 301, and the top end of the tension spring 301 is arranged on the die frame 200. The tension spring 301 is a kind of helical spring, mainly used for bearing axial tension. Its working principle is to store energy by stretching or compressing the spring, and release the energy after the external force disappears. The specifications and models of the tension spring 301 can be set according to actual needs, and therefore, the application does not make specific limitation on the same.

[0044] In the above embodiments, during the license plate stamping process, the main function of the tension spring 301 is to provide a rebound force to help the character die composed of the die frame 200 and the pressing cover 201 quickly return to the initial state after completing stamping. This function is very important to ensure the normal operation of the character die and improve the accuracy of the finished product. In addition, the tension spring 301 can also be used to maintain the tension of the character die to ensure stability and consistency during the stamping process. During the stamping process, the die frame 200 can move vertically up and down along the guide rod 500.

[0045] In some embodiments, referring to Figure 2 The die frame 200 in the present application is provided with a fixed groove 203 with a predetermined depth, which is used to fix the license plate.

[0046] In the above embodiments, the fixed groove 203 is used to better fix the license plate in the die frame 200 to ensure the pressing effect of the license plate. The predetermined thickness can be set according to the thickness of the license plate, and therefore, the present application does not make specific limitations on it.

[0047] In some embodiments, referring to Figure 1 and Figure 2 Each slide rail 300 in the present application corresponds to at least two sliding blocks 400, and each adjacent two sliding blocks 400 corresponding to each slide rail 300 are arranged on the operation platform with a predetermined distance.

[0048] In the above embodiments, since the slide rail 300 has a certain length, and at least two sliding blocks 400 can ensure the stability of the horizontal movement of the slide rail 300, the number of sliding blocks 400 and the predetermined distance can be set according to actual needs, and the present application does not make specific limitations on them.

[0049] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features. Such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
