Description

Technical Field

[0001] The utility model belongs to the technical field of circular knife die cutting, and particularly relates to a quick-locking guide shaft with a material breaking alarm function. Background Art

[0002] The design and manufacturing quality of the circular knife holder have a significant impact on the performance and service life of the die-cutting machine. When selecting and using a circular knife holder, factors such as its material, structure, precision and stability need to be considered. The die-cutting rubber roller in the circular knife holder plays the role of crimping the conveyor belt. The belt may break during the conveying process. The conventional way to detect whether there is a break is to set a sensor in the conveying direction of the belt. The sensor needs to be installed outside the circular knife holder, which has installation restrictions. Utility Model Content

[0005] Specifically, the guide shaft assembly is installed in the die-cutting tool holder through a fixed shaft seat.

[0006] Specifically, the guide shaft assembly includes a guide shaft and a die-cutting rubber roller sleeved on the outside of the guide shaft.

[0007] Specifically, the surface of the die-cutting rubber roller guides the material strip.

[0008] Compared with the prior art, the beneficial effects of the quick-lock guide shaft with material breaking alarm function of the utility model are mainly reflected in:

[0009] A proximity sensor is arranged on the end side of the guide shaft assembly, which can accurately detect the rotation state of the guide shaft assembly, and then accurately determine whether there is a material breakage problem in the material belt, and the detection is efficient and accurate.

[0014] The technical solutions in the embodiments of the present utility model are clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] Example:

[0016] Reference Figure 1-2 As shown, this embodiment is a quick-lock guide shaft with a material break alarm function, including a fixed shaft seat 1, a guide shaft assembly 2 axially connected to the fixed shaft seat 1, a proximity sensor 3 arranged on the fixed shaft seat 1, and a toothed disc 4 arranged on the end face of the guide shaft assembly 2 and coaxially rotating therewith and corresponding to the proximity sensor 3. The toothed disc 4 includes a plurality of tooth blocks 41 arranged at equal intervals on the circumference, and the plurality of tooth blocks 41 rotate in a cycle to approach the proximity sensor 3 for induction.

[0017] In this embodiment, the guide shaft assembly 2 is installed in the die-cutting knife seat (not shown in the figure) through the fixed shaft seat 1. The guide shaft assembly 2 includes a guide shaft and a die-cutting rubber roller 21 sleeved on the outside of the guide shaft. The guide shaft is connected and fixed to the fixed shaft seat 1, and the conventional die-cutting rubber roller 21 is in a rotating state. The surface of the die-cutting rubber roller 21 conveys the guide material belt (not shown in the figure). When working normally, the guide shaft assembly 2 is pulled by the material belt and is in a rotating state, and the corresponding toothed disc 4 rotates synchronously. The proximity sensor 3 is installed on the fixed shaft seat 1 and is in a positioning state and does not follow the rotation. The rotation cycle of several tooth blocks 41 on the toothed disc 4 forms an induction signal of a certain frequency with the proximity sensor 3. The proximity sensor 3 transmits the detection signal to the alarm system. When the guide shaft assembly 2 does not rotate, that is, there is a problem of material breaking in the material belt, the toothed disc 4 does not rotate, and the tooth block 41 is in a state close to the proximity sensor 3 or far away from the proximity sensor 3. When the proximity sensor 3 cannot detect a signal with a certain frequency of regular changes, it indicates that there is a problem of material breaking, that is, the alarm system sends an alarm indication.

[0018] When this embodiment is applied, a proximity sensor 3 is provided on the end side of the guide shaft assembly 2, which can accurately detect the rotation state of the guide shaft assembly 2, and further accurately determine whether there is a material breakage problem in the material belt, and the detection is efficient and accurate.
