Description

Technical Field

[0001] The utility model relates to the field of cigarette packaging machine equipment, and more specifically to a device for detecting stacking skewness of trademark paper storage of a cigarette packaging machine. Background Art

[0002] Cigarette packaging equipment utilizes multiple packaging wheels or tracks to combine cigarettes, liner paper, inner frame paper, and label paper into packs. Label paper for small rigid packs is fed into a label paper magazine in stacks of 500 sheets. A suction device at the bottom of the magazine separates the labels from the bottom layer and feeds them to the subsequent packaging station. During the feeding process, the label paper stacks can easily tilt or overturn due to various reasons, such as uneven stacking and improper feeding. Failure to detect these tilted labels can damage the equipment, seriously impacting its operation. Utility Model Content

[0003] One purpose of the utility model is to provide a new technical solution for a device for detecting stack skewness of trademark paper magazines in cigarette packaging machines, so as to solve the technical problems raised in the above-mentioned background technology.

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] according to Figure 1 and Figure 2 As shown, the utility model provides a device for detecting stack skewness of a label paper magazine of a cigarette packaging machine, comprising a support 4, a movable arm 9 and a proximity switch 1;

[0027] A groove is provided on one side of the support 4. The middle part of the movable arm 9 is rotatably connected to the groove via a pin 7. The bottom of the movable arm 9 extends along the bottom of the support 4 into the trademark paper stock, and contacts the bottom of the trademark paper stack, so that pressure is applied to the movable arm 9 through the trademark paper stack.

[0028] The top of the movable arm 9 extends above the support 4, and the proximity switch 1 is set on the top of the support 4 and detects the top position of the movable arm 9; when the trademark paper stock is stacked skewed, the trademark paper pile deviates from the bottom of the movable arm 9, and the movable arm 9 can rotate around the pin 7 so that the top of the movable arm 9 deviates from the proximity switch 1.

[0029] The cigarette packaging machine trademark paper magazine stack skew detection device disclosed by the utility model fixes the support 4 at different positions on the side plate of the trademark paper magazine, and one end of the movable arm 9 extends into the trademark paper magazine and contacts the bottom of the trademark paper pile, and at the same time presses the movable arm 9 to prevent the movable arm 9 from rotating around the pin shaft 7; when the trademark paper pile is stacked tilted, as the suction device at the bottom of the trademark paper magazine gradually sucks and separates the trademark paper at the bottom of the paper magazine, the trademark paper pile gradually deviates from the position of the movable arm 9 until it no longer presses the movable arm 9. At this time, the movable arm 9 swings clockwise around the pin shaft 7. At this time, the proximity switch 1 sends a signal because it cannot detect the movable arm 9, so that the equipment is shut down in time.

[0030] Furthermore, a spring 3 is provided between the top of the movable arm 9 and the end surface of the groove. When the label paper pile no longer presses the movable arm 9, the movable arm 9 can be quickly ejected under the action of the spring 3, avoiding the problem of untimely detection.

[0031] Furthermore, a limiting rod 8 is provided between the two sides of the groove, and the movable arm 9 is located inside the limiting rod 8 to limit the rotation angle of the movable arm 9. A limiting groove 10 is provided on the side of the movable arm 9 facing the limiting rod 8, and the limiting groove 10 and the limiting rod 8 are consistent with each other.

[0032] In this embodiment, since the spring 3 applies a certain force to the movable arm 9 and the bottom of the movable arm 9 is located inside the trademark paper magazine, in order to prevent the movable arm 9 from rotating too much and causing damage to the trademark paper magazine, the rotation angle of the movable arm 9 is limited by the limit rod 8.

[0033] Furthermore, the limiting rod 8 is connected to the two sides of the groove by threads. The limiting rod 8 is a bolt structure, and the other end of the limiting rod 8 is connected by a nut. In this embodiment, the limiting rod 8 is detachably connected to the support 4, which makes it easier to inspect or replace the movable arm 9.

[0034] Furthermore, a plurality of screw holes 11 are provided on the side of the support 4 away from the groove to fix the support 4 to the side plate of the trademark paper storage by screws. The plurality of screw holes 11 ensure a firm connection between the support 4 and the trademark paper storage, thereby ensuring the accuracy of the detection.

[0035] Furthermore, a connection hole 12 is provided on the top of the support 4, and the connection hole 12 is connected to the bracket 2 by screws, and the proximity switch 1 is fixed on the bracket 2. The bracket 2 and the support 4 are detachable, and when the proximity switch 1 fails, it can be disassembled and repaired or replaced in time.

[0036] Furthermore, the bottom of the movable arm 9, extending into the label paper stack, is connected to a rolling bearing 5 via a fixed shaft 6. The outer ring of the rolling bearing 5 contacts the bottom of the label paper stack. A suction device at the bottom of the label paper stack extracts and separates the label paper from the bottom layer of the stack and delivers it to the subsequent packaging station. The utility model utilizes the rolling bearing 5 to convert sliding friction between the movable arm 9 and the label paper into rolling friction, reducing the friction coefficient and preventing unnecessary damage to the label paper caused by the movable arm 9.

[0037] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
