Description

Technical Field

[0001] This utility model belongs to the field of surplus material alarm technology, specifically relating to a surplus material alarm device. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, CNC punching machines, or servo hydraulic punching machines, are essential equipment for post-printing packaging processing. They utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through a printing plate, cutting printed materials or cardboard into specific shapes. The main processes include plate mounting, pressure adjustment, alignment, substrate pasting, trial die-cutting, formal die-cutting and creasing, waste removal, and finished product winding or sheet cutting.

[0003] The existing die-cutting machine's feeding shaft only uses the machine's built-in setting of the core diameter to determine the remaining material length in meters, and then activates the alarm device to stop the machine. Because the material is very thin, the diameter measurement is inaccurate, and the alarm often sounds when there is a lot of material left, or when the material is completely used up and the machine runs out of material. The overall practicality of the device is poor, and it cannot be well adjusted according to different work requirements. Therefore, a material surplus alarm device is needed to help solve this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a residual material alarm device, such as... Figure 1 and Figure 2As shown, the residual material alarm device includes a first fixed frame 1 and a second fixed frame 2. A leveling knob is threaded onto the bottom of both the first and second fixed frames 1 and 2. A receiving frame 3 is installed at the top of the second fixed frame 2. A die-cutting roller 4 is rotatably mounted inside the receiving frame 3. A die-cutting blade 41 protrudes from the outer edge of the die-cutting roller 4. A rotating motor 5, which assists in the rotation of the die-cutting roller 4, is installed on one side of the receiving frame 3. A guide plate 17 is inclinedly mounted on the side of the first fixed frame 1 away from the first fixed frame 1. The guide plate 17 ensures stable material guidance during operation. A protruding frame 6 is symmetrically fixed on the side of the receiving frame 3 facing the first fixed frame 1. A rotating shaft 7 is rotatably mounted on the protruding frame 6 at equal intervals. The cooperation between the protruding frame 6 and the rotating shaft 7 ensures stable conveying of films and other materials during operation.

[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown, a fixing ring 10 is installed at the top of the first fixing frame 1 by a hinge. A protruding block 101 is provided at the end of the fixing ring 10 away from the hinge. A positioning bolt 11 is rotatably provided at the top of the protruding block 101. A positioning hole 111 is drilled in the inclined section of the first fixing frame 1. The positioning bolt 11 and the positioning hole 111 are threadedly engaged.

[0028] The material body 9 can be easily and quickly disassembled and replaced before and after operation by means of the fixed ring 10, which is hinged to the top of the first fixed frame 1, and the positioning bolts 11 and positioning holes 111.

[0029] Limiting grooves 102 are provided at the top of the first fixing frame 1 and the inner bottom of the fixing ring 10. A limiting ring 81 is sleeved and installed on the outer edge of the feeding shaft 8. The limiting ring 81 and the limiting groove 102 are engaged and locked together. Through the engagement between the limiting groove 102 and the limiting ring 81, the feeding shaft 8 can be stably fixed in the corresponding position during operation.

[0030] Reference Figure 1 , Figure 2 and Figure 4As shown, symmetrically protruding identification color rings 82 are provided on the feeding shaft 8. A feeding motor 12 that drives the feeding shaft 8 to rotate is installed on the first fixed frame 1. At the bottom of the first fixed frame 1, directly below the feeding shaft 8, an alarm component 13 is installed to assist the material body 9 on the feeding shaft 8 in alarming. The alarm component 13 includes a fixed rod 14 fixed on the first fixed frame 1. A collar 15 is sleeved on the fixed rod 14. A photoelectric color mark sensor 16 that cooperates with the identification color rings 82 to trigger an alarm is installed on one side of the collar 15. The photoelectric color mark sensor 16 is a Jingjiake LX-101 color mark photoelectric switch color sensor. This model can be used, but is not limited to, this model. In actual operation, the feeding motor 12 and the photoelectric color mark sensor 16 can be controlled by PLC programming. An alarm can be installed on the fixed rod 14. The fixed rod 14 has a horizontal sliding groove 141. A sliding block 151 is protruding from the inner edge of the collar 15. The sliding groove 141 and the sliding block 151 slide together. A fixing bolt 152 is threaded on one side of the collar 15. One end of the fixing bolt 152 is set in the sliding groove 141. Through the cooperation between the collar 15 and the fixing bolt 152, the position of the photoelectric color mark sensor 16 can be effectively adjusted according to the position of the identification color ring 82.

[0031] By cooperating with the identification color ring 82 set on the feeding shaft 8 and the anticipatory alarm component 13 at the bottom of the feeding shaft 8, the photoelectric color mark sensor 16 on the fixed rod 14 illuminates the material body 9 on the feeding shaft 8. Color analysis can detect whether there is material. When the photoelectric color mark sensor 16 on the fixed rod 14 illuminates the identification color ring 82 on the feeding shaft 8, and color analysis shows that there is not much material left, the die-cutting operation is stopped and an alarm is triggered to avoid situations such as die-cutting.

[0032] The aforementioned sliding groove 141 is fitted with a scale plate 142, which is engraved with scale lines. The scale plate 142 can be used to effectively determine the overall position of the collar 15 after adjustment during operation.

[0033] Working principle:

[0034] When the feeding shaft 8 needs to be installed, the feeding shaft 8 is mounted on the top of the first fixed frame 1. The fixed ring 10 is rotated to cover the top of the first fixed frame 1. The positioning bolt 11 is rotated, and the positioning bolt 11 is threadedly engaged with the positioning hole 111, thereby stably covering the top of the feeding shaft 8. The material body 9 on the feeding shaft 8 is passed through the rotating shaft 7 in sequence, and the material body 9 is located at the bottom of the die-cutting roller 4. During operation, the rotating motor 5 is started, and the rotating motor 5 drives the die-cutting roller 4 to rotate as a whole. The die-cutting roller 4 drives the die-cutting blade 41 to rotate as a whole, and then the die-cutting blade 41 on the die-cutting roller 4 performs die-cutting work on the material body 9.

[0035] During operation, the photoelectric color mark sensor 16 on the fixed rod 14 illuminates the material body 9 on the feeding shaft 8. Color analysis can detect whether the material is present. When the photoelectric color mark sensor 16 on the fixed rod 14 illuminates the identification color ring 82 on the feeding shaft 8, color analysis shows that there is not much material left. At this time, the die-cutting operation is stopped and an alarm is triggered to avoid situations such as die-cutting.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
