DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 Figures 1-4 , the present utility model provides a technical solution: a non - adhesive device for a slitter, including a slitter main body 1. A mounting seat 2 is fixedly arranged on the outer surface of the cylinder housing of the slitter main body 1. An L - shaped mounting frame 3 is hinged on the mounting seat 2. The mounting frame 3 is arranged in the running direction of the non - woven fabric when the slitter main body 1 slits the non - woven fabric. An auxiliary cutter 4 is arranged at one end of the mounting frame 3 far from the mounting seat 2. The cutting edge direction of the auxiliary cutter 4 faces the direction of the cutter on the slitter main body 1, and the end of the auxiliary cutter 4 is farther than the end of the cutter on the slitter main body 1, so as to ensure that when the slitter main body 1 cannot slit the non - woven fabric normally, the non - woven fabric can be slit by the auxiliary cutter 4. By arranging the mounting frame 3 and the auxiliary cutter 4 in the running direction of the non - woven fabric when the non - woven fabric is slit, and making the cutting edge of the auxiliary cutter 4 face the direction of the cutter, the non - woven fabric is first slit by the cutter of the slitter main body 1 and then passes through the auxiliary cutter 4. When the cutter fails, the non - woven fabric can be slit by the auxiliary cutter 4, avoiding the adhesion situation, reducing raw material waste and economic losses, etc., and reducing the impact on the subsequent processing of the non - woven fabric.

[0019] In a preferred technical solution, a connecting device is arranged between the mounting frame 3 and the cutter cover of the slitter main body 1, which is used to cooperate with the mounting seat 2 to limit and fix the position of the mounting frame 3 to ensure the normal operation of the device.

[0020] Specifically, the connecting device includes a sliding seat 6 hinged on the side surface of the mounting frame 3 and a fixed seat 5 hinged on the outer surface of the cutter cover of the slitter main body 1. A chute 10 is opened on the side surface of the fixed seat 5, and the sliding seat 6 is slidably arranged in the chute 10. Since the mounting seat 2 is hinged to the mounting frame 3 through a pin shaft, when the slitter main body 1 fails, the non - woven fabric is cut by the auxiliary cutter 4, and the auxiliary cutter 4 and the mounting frame 3 will rotate in the conveying direction of the non - woven fabric driven by the non - woven fabric. At this time, the sliding seat 6 slides in the chute 10 of the fixed seat 5, so that the whole mounting frame 3 rotates around the pin shaft on the mounting seat 2, which can play a certain buffering role on the mounting frame 3 and the slitter main body 1, etc., avoiding damage to the auxiliary cutter 4, the mounting frame 3 and the slitter main body 1, etc. caused by the high - speed moving non - woven fabric, and prolonging the overall service life of the device.

[0021] In a preferred technical solution, a spring 11 is arranged in the chute 10. One end of the spring 11 is fixedly connected to the sliding seat 6. The spring 11 is a tension spring and is in a compressed state when not under load, tightly pulling the sliding seat 6 against the inner side of the chute 10, so that the mounting frame 3 is kept parallel to the side of the slitter main body 1. When a fault occurs in the slitter main body 1, the non-woven fabric is cut by the auxiliary cutter 4, and the mounting frame 3 rotates in the conveying direction of the non-woven fabric driven by the non-woven fabric, causing the sliding seat 6 to move outward, thereby stretching the spring 11. When the slitter main body 1 is shut down for maintenance, the non-woven fabric is no longer conveyed, and the sliding seat 6 is reset under the pulling force of the spring 11.

[0022] In a further preferred technical solution, two stoppers 13 are symmetrically arranged at the outer end of the inner surface of the chute 10. A baffle 12 corresponding to the stoppers 13 is arranged on one side surface of the sliding seat 6 located in the chute 10. When the sliding seat 6 slides outward, the baffle 12 will be blocked by the stoppers 13, thereby playing a limiting role to prevent the sliding seat 6 from detaching from the fixed seat, ensuring that the auxiliary cutter 4 can play an auxiliary cutting role on the non-woven fabric. The spring 11 is connected to the baffle 12, and a proximity switch 14 is arranged on the side surface of the stopper 13 facing the baffle 12. An alarm device electrically connected to the proximity switch 14 is arranged on the mounting frame 3. When the sliding seat 6 moves outward to the limiting position, at this time, the fault of the slitter main body 1 is relatively serious and it can no longer cut the non-woven fabric, and the auxiliary cutter 4 is not sufficient to complete the cutting work and receives a large impact force, so it drives the mounting frame 3 to rotate outward, thereby causing the sliding seat 6 to move outward to the limiting position, and the baffle 12 contacts the proximity switch 14 on the stopper 13, thereby triggering the proximity switch 14 and turning on the alarm device, which can timely remind the staff to come and check and shut down for maintenance, etc., further reducing raw material waste and economic losses, etc.

[0023] In a further preferred technical solution, the alarm device includes a flashing light 8 and a buzzer 9 installed on the side surface of the mounting frame 3. Both the flashing light 8 and the buzzer 9 are electrically connected to the proximity switch 14, and the proximity switch 14 is electrically connected to an external power supply. Through the audible and visual alarm of the flashing light 8 and the buzzer 9, the staff can quickly locate the slitter with a fault, and the handling is faster and more convenient.

[0024] The slitter main body 1, proximity switch 14, flashing light 8, buzzer 9, etc. used in this application are all common electronic components in the prior art, and their specific structures, working principles, circuit connections, etc. are all well-known technologies and will not be elaborated here.

[0025] In a preferred technical solution, a groove is formed on the side surface of the mounting frame 3, the auxiliary cutting knife 4 is slidably arranged in the groove, and a screw hole communicating with the groove is formed on the side surface of the mounting frame 3. A fixing bolt 7 for fixing the auxiliary cutting knife 4 is threadedly connected in the screw hole. The length of the auxiliary cutting knife 4 can be flexibly adjusted according to the diameter of the cutting knife on the slitter main body 1, so that the device is applicable to different models of slitters, etc., improving the universality.

[0026] Parts not disclosed in the present utility model are all prior arts, and their specific structures, materials and working principles will not be elaborated herein. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
