Description
TECHNICAL FIELD
[0001] The application belongs to the field of die-cutting equipment, and particularly relates to a pressure adjusting structure of a round-to-round die-cutting device. BACKGROUND
[0002] In the existing round-to-round die-cuting device, in order to facilitate the replacement of materials of different thicknesses or types, a spring is usually arranged between the pressure roller and the pressure receiving roller as part of the pressure adjusting mechanism. However, this design has some problems in actual application. First, since the spring always has an automatic restoring force, when the pressure roller approaches the pressure receiving roller, the spring will generate a continuous resistance. This resistance not only increases the energy consumption in the die-cutting process, but also may affect the precision and stability of die-cutting. Second, even if the pressure between the pressure roller and the pressure receiving roller is adjusted to the right position through the adjusting mechanism, the spring force will continue to act, causing the adjusting mechanism to be in a stressed state for a long time. This continuous stressed state will accelerate the fatigue and wear of the structure, and even may cause the failure of the adjusting mechanism. In addition, the spring force will gradually weaken with the increase of the use time, which further increases the instability of the adjusting mechanism. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0040] Please refer to Figure 1 And Figure 2 , now a kind of round pressure round die cutting device pressure regulating structure provided by the embodiment of the present application will be described. The round pressure round die cutting device pressure regulating structure includes card house seat 101, top plate 102, slider 103, pull rod 104, nut sleeve 105, die cutting roller group and adjusting assembly. Wherein:
[0041] The two plate frames 101 are arranged in parallel and at intervals, and the top plate 102 is connected to the top end of the plate frame 101. The two sliding blocks 103 are arranged in sliding connection with the plate frame 101. The pull rod 104 is connected to the sliding block 103 and movably penetrates the top plate 102. The nut sleeve 105 is threadedly connected to the pull rod 104 and is arranged on the opposite sides of the top plate 102 with the sliding block 103. The axial direction of the nut sleeve 105 is parallel to the sliding direction of the sliding block 103. The die cutting roller set includes the pressure roller 106 and the compression roller 107 arranged in parallel. The pressure roller 106 is rotatably installed on the plate frame 101, and the compression roller 107 is rotatably installed on the sliding block 103. The adjusting assembly is arranged in abutment with the side of the compression roller 107 away from the pressure roller 106 and is used to drive the compression roller 107 to move close to the pressure roller 106.
[0042] According to the above structure provided in the embodiment, in the pressure adjusting structure of the round-to-round die cutting device provided in the embodiment, the adjusting assembly is arranged in abutment with the side of the compression roller 107 away from the pressure roller 106 and can drive the compression roller 107 to move close to the pressure roller 106. Since the compression roller 107 is rotatably installed on the sliding block 103 and the sliding block 103 is in sliding connection with the plate frame 101, and since the nut sleeve 105 threadedly connected to the pull rod 104 is arranged on the opposite sides of the top plate 102 with the sliding block 103 and the axial direction of the nut sleeve 105 is parallel to the sliding direction of the sliding block 103, when the die cutting material needs to be replaced, the adjusting assembly can be first removed from the compression roller 107, and then the nut sleeve 105 can be screwed relative to the pull rod 104. When the nut sleeve 105 is rotated to abut against the top plate 102, the pull rod 104 can be moved along the axial direction of the nut sleeve 105 by continuously screwing the nut sleeve 105, so that the sliding block 103 connected to the pull rod 104 and the compression roller 107 installed on the sliding block 103 can move away from the pressure roller 106 under the action of the pull rod 104. Therefore, the pressure adjusting structure of the round-to-round die cutting device provided in the embodiment does not need to be provided with a spring between the compression roller 107 and the pressure roller 106 for the convenience of replacing the die cutting material, and correspondingly, the pressure adjusting structure of the round-to-round die cutting device provided in the embodiment can have good structural stability, which is much better than the prior art.
[0043] It should be noted that in the process of driving the compression roller 107 to move close to the pressure roller 106 by the adjusting assembly, the nut sleeve 105 needs to be moved relative to the pull rod 104 and form a certain distance interval between the nut sleeve 105 and the top plate 102, so that the pull rod 104 can be moved relative to the top plate 102 in the process of moving the sliding block 103 driven by the compression roller 107, thereby realizing the pressure adjusting effect of the pressure adjusting structure of the round-to-round die cutting device provided in the embodiment.

The connecting seat 109 and the knuckle bearing 110 are hingedly connected to each other so that the sliding block 103 is connected to the pull rod 104. According to the above structure provided in the embodiment, the hingedly connected connecting seat 109 and knuckle bearing 110 can eliminate a part of installation errors between the pull rod 104 and the sliding block 103, so that a more stable connection between the pull rod 104 and the sliding block 103 can be formed, thereby further improving the structural stability of the pressure adjusting structure of the round-to-round die cutting device in the embodiment.

In addition, since the axial direction of the threads between the shaft sleeve 112 and the sliding block 103 is parallel to the axial direction of the pressure roller 107, when the shaft sleeve 112 rotates around its central axis relative to the sliding block 103, the pressure roller 107 can be driven to move along its axial direction. Thus, the relative position relationship between the pressure roller 107 and the pressure receiving roller 106 in the axial direction of the pressure roller 107 can be flexibly adjusted, so that the pressure adjusting structure of the round-to-round die cutting device provided in the embodiment can be applied to more die cutting scenarios.
