Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a small box transparent paper cutter with vibration detection for a ZB48A packaging machine. Background Technique

[0002] In the cigarette packaging industry, the precise cutting of the small box transparent paper in the ZB48A packaging machine is a key link to ensure the appearance quality and packaging efficiency of cigarette packs. The existing design of the small box transparent paper cutter adopts a structure of a fixed knife and a moving knife separated left and right (see Figure 16 ). The openable left channel door is installed at the uppermost position of the machine base by a rotating shaft. Among them, the fixed knife structure is installed below the openable left channel door, and the moving knife is fixed on the shaft inside the right machine base. The two knives are arranged at a certain angle between them, so that the cutting of the small box transparent paper is a shearing motion; when the small box transparent paper tape with the pull wire pasted passes by, the rotating moving knife and the fixed fixed knife cut the small box transparent paper tape into single small box transparent papers for wrapping the small box cigarette packs. Although this design meets the cutting requirements to a certain extent, many defects have been exposed in actual applications, seriously restricting the further improvement of production efficiency and product quality.

[0003] First of all, during the frequent opening and closing process of the left and right channel doors, due to the gaps and wear of the mechanical structure, it is difficult to keep the gap between the moving knife and the fixed knife constant. Considering the extremely thin characteristics of the small box transparent paper (only 23μm), this tiny gap change directly affects the cutting accuracy and stability. At worst, it may cause incomplete cutting, and at best, it will accelerate the wear of the tool and bearing, intensify the vibration of the paper feeding channel, and then affect the stable operation of the entire packaging line.

[0004] Secondly, during daily operations, such as threading the transparent paper or dealing with blockage faults, the operator needs to frequently open and close the paper feeding channel door. If the moving knife and the fixed knife happen to be in the cutting position at this time, it is very easy to accidentally knock the cutting knife due to improper closing force, and in severe cases, it may even cause damage to the cutting knife, increasing the maintenance cost and downtime.

[0005] Furthermore, the installation position of the fixed knife is affected by the clearance of the rotating pair between the left channel door bracket and the shaft, resulting in a problem of insufficient positioning accuracy. This fluctuation of positioning accuracy further reduces the cutting accuracy and consistency, posing a potential threat to product quality.

[0006] Finally, the existing cutting knife system lacks a real-time monitoring and feedback mechanism for the cutting state. During the high-speed operation of the equipment, once the gap changes due to reasons such as cutting knife wear and bearing damage, it is often difficult to detect and adjust in time, thus affecting the stability and reliability of the cutting quality.

[0007] In summary, the existing small box transparent paper cutter technology has problems such as poor positioning accuracy, fast wear, insufficient stability, and lack of monitoring. Therefore, it is of great significance to develop a new type of small box transparent paper cutter that can overcome the above defects, achieve high precision, long life, stable operation, and have a real-time monitoring function for improving the overall level of the cigarette packaging industry.

[0009] To solve the above problems and achieve the above purpose, the utility model adopts the following technical solutions:

[0012] A fixed knife seat (11), there are several screw holes of different sizes on the fixed knife seat (11), and the fixed knife seat (11) is detachably connected to the machine base (3) through fixed knife seat bolts (111), positioning pins (112), hexagon bolts (113), fixed knife seat side stop screws (114), and fixed knife seat lower stop screws (115);

[0013] A side pressing block (12), the side pressing block (12) is a rectangular structure with several screw holes on it, and the side pressing block (12) is connected between the fixed knife seat (11) and the machine base (3) to enhance the connection stability;

[0025] The utility model replaces the original fixed knife mechanism arranged on the channel door through a brand-new design of the fixed knife mechanism. Its working principle is as follows: The fixed knife mechanism (1) is the core part of the entire cutting knife system. It is firmly installed on the machine base (3) through various connecting parts, such as the knife seat bolt (111), positioning pin (112), hexagon bolt (113), fixed knife seat side stop screw (114), fixed knife seat bottom stop screw (115), etc. The addition of the side pressing block (12) enhances the stability of the connection, ensuring that the fixed knife mechanism (1) will not loosen during the operation of the equipment.

The moving knife mechanism (2) includes a moving knife rotating shaft body (21), a moving knife seat (22) and a moving knife (23); the moving knife (23) realizes rotational motion on the machine frame through the moving knife seat (22) and the moving knife rotating shaft body (21), and cooperates with the fixed knife mechanism (1) to complete the cutting action.

[0058] A moving knife mechanism 2, the moving knife mechanism 2 is detachably connected to the machine base 3.

[0059] The fixed knife mechanism 1 is the core part of the entire cutter system, and it is firmly installed on the machine base 3 through various connecting parts such as a knife seat bolt 111, a positioning pin 112, a hexagon bolt 113, a fixed knife seat side stop screw 114, and a fixed knife seat bottom stop screw 115. The addition of the side pressing block 12 enhances the connection stability and ensures that the fixed knife mechanism 1 will not loosen during the operation of the equipment.

[0060] Furthermore, as Figure 12 、 Figure 13 shown, there are several screw holes on the knife pressing plate 13 corresponding to the fixed knife seat 11 one by one, and there is a wavy notch 131 for reducing the adsorption friction of the small box transparent paper 4 on one side of the knife pressing plate 13.

[0061] Specifically, as Figure 14As shown, there is a rectangular notch 141 on the fixed knife 14 for avoiding the pulling wire of the transparent paper 4 of the small box.

[0062] Specifically, as Figure 15 shown, the vibration detection device 16 is a capacitive vibration sensor.

[0069] In summary, a more specific implementation manner of the present invention is:

[0070] Embodiment 1

[0071] In this embodiment, two capacitive vibration sensors of model VSM103 are selected for the vibration detection device 16, and the remaining components are prefabricated in the factory. A wavy notch 131 is cut on the back of the pressing knife plate 13, i.e., the side in contact with the small box transparent paper 4, to reduce the adsorption friction force of the small box transparent paper 4 during the cutting process, enabling the small box transparent paper 4 to be smoothly conveyed downward and avoiding poor cutting or paper jamming phenomena.

[0072] First, install the moving knife mechanism 2 including the moving knife rotating shaft body 21, the moving knife seat 22, and the moving knife 23 on the machine base 3 according to the design requirements, and ensure that the connections between the components are firm and reliable.

[0073] Furthermore, according to the position of the moving knife mechanism 2, thread holes and positioning pin holes for installing the fixed knife seat 11 are precisely machined on the machine base 3. Then, both sides of the fixed knife seat 11 are fixedly connected to both sides of the machine base 3 through three fixed knife seat bolts 111 and one positioning pin 112, ensuring that all screws are tightened in place and the positioning pin 112 fits tightly with the hole, thereby ensuring the stability and positioning accuracy of the fixed knife seat 11 on the machine base 3; thread holes are machined on the side plate of the fixed knife seat 11, and after installing the side stop screw 114 of the fixed knife seat, it is used to limit the left and right positions of the fixed knife 14 within the fixed knife seat 11. Thread holes are also machined below the side plate and the lower stop screw 115 of the fixed knife seat is installed to lock the position of the side stop screw 114 and prevent it from loosening during operation.

[0074] Furthermore, the pressing knife plate 13 is fitted with five fixed knife bolts 15 on the fixed knife seat 11 for clamping the fixed knife. During the clamping process, it is necessary to ensure that the installation surface of the fixed knife 14 is in close contact with the fixed knife seat 11, and the pressing knife plate 13 and the fixed knife bolts 15 are pre-tightened in place to ensure the stability of the fixed knife 14 during the cutting process.

[0075] Furthermore, install the vibration detection device 16 closely against the fixed knife seat 11 through the vibration detection bolt 161, ensuring that the contact between the vibration detection device 16 and the fixed knife seat 11 is close and stable, and connecting the corresponding signal wires and power supply wires to transmit the vibration signal to the control system for processing.

[0076] Furthermore, by adjusting the relevant components of the moving knife mechanism 2, the cooperation between the moving knife 23 and the fixed knife 14 is brought to the best state to ensure that the moving knife can gently cut the small box transparent paper 4; complete the installation and debugging of this cutting knife device.

[0077] Further, during the operation of the device, the vibration detection device monitors the vibration condition during the cutting process in real time and transmits the signal to the control system. Corresponding program logic is set in the control system. When the amplitude value monitored by the vibration detection device exceeds the set limit value, the system automatically triggers the fault warning mechanism, controls the device to stop running and displays the fault information so that the operator can handle it in time.

[0078] Finally, it should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
