Description

Technical Field

[0001] The utility model relates to the technical field of small box transparent paper packaging machines, in particular to a driving device for a cigarette packaging machine. Background Art

[0002] After the cigarettes are packed into small boxes, they need to pass through a small box transparent paper packaging machine, wrap transparent paper on the small boxes, and then be transported to a carton packaging machine. After being packed into strips, they pass through a carton transparent paper packaging machine to be packaged into complete cigarette strips.

[0003] At present, small box transparent paper packaging machines, strip box packaging machines and strip box transparent paper packaging machines are synchronous power transmission, such as Figure 1-2 As shown, the main motor 1 of the small box transparent paper packaging machine drives the pulley 2 to rotate and transmits power to the main shaft 4A. The main shaft 4A transmits power to the strip box packaging machine and the strip box transparent paper packaging machine through gear transmission. A clutch is provided at the end of the main shaft 4A. The function of the clutch is to protect the equipment from being blocked when the feed conveyor belt is blocked and to avoid squeezing the equipment. The gear 3A on the main shaft 4A transmits power to the main gear 3B. The main gear 3B rotates on the transmission shaft 4B. There is a groove under the tooth clutch 5. This groove cooperates with the raised block on the main gear 3B to form a tooth clutch. The tooth clutch 5 is connected to the transmission shaft 4B through a key. The power of the tooth clutch 5 is transmitted to the transmission shaft 4B, driving the transmission shaft 4B to rotate continuously, and transmitting power to the transparent paper and wire conveying and cutting system (including the suction belt conveying mechanism, the wire cutting mechanism, the transparent paper conveying mechanism and the transparent paper cutting mechanism, etc.).

[0004] When the small box transparent paper packaging machine has problems such as transparent paper breaking, wrong teeth of the drawstring, and protruding overlap of the side transparent paper, since these three machines are in a rotating route, it will lead to a lot of labor when maintaining the small box transparent paper packaging machine. For example:

[0005] In the normal process of the equipment, the U-shaped wire cutting knife and the transparent paper cutting knife will be worn. When they are worn to a certain extent, they need to be replaced. Therefore, after replacing the U-shaped wire cutting knife or the transparent paper cutting knife, the equipment needs to be rotated continuously during the debugging process, and then the cutting state of the U-shaped wire cutting knife or the transparent paper cutting knife meets the adjustment technical requirements. In this way, frequent rotation of the equipment during the replacement and debugging of the U-shaped wire cutting knife and the transparent paper cutting knife causes a lot of time waste and causes a large number of semi-finished cigarette packs to be rejected, which not only affects the effective operation rate of the equipment but also increases the labor intensity of maintenance personnel.

[0006] Based on this, it is necessary to improve the driving device of the small box transparent paper packaging machine to improve the work efficiency during maintenance of the small box transparent paper packaging machine and reduce the workload. Utility Model Content

[0007] In view of the above problems, the utility model provides a driving device for a cigarette packaging machine, which separates the independent operating power of the transparent paper and wire conveying and cutting system of the small box transparent paper packaging machine from the power of the strip box packaging machine and the strip box transparent paper packaging machine, and drives them separately, thereby solving the problem of frequent rotation of the equipment during maintenance of the transparent paper and wire conveying and cutting system of the small box transparent paper packaging machine, resulting in a large amount of time being wasted and a large number of semi-finished cigarette packs being discarded, affecting the effective operation rate of the equipment and increasing the labor intensity of maintenance personnel.

[0008] Specifically, the utility model provides a driving device for a cigarette packaging machine, comprising:

[0009] Main motor;

[0010] A main shaft, wherein the main motor is drivingly connected to the main shaft;

[0011] transmission shaft;

[0012] PLC;

[0013] A servo motor, wherein a reducer is provided at the output end, a first bevel gear is provided at the output end of the reducer, and the first bevel gear is connected to the transmission shaft through a transmission assembly;

[0014] An encoder is provided on the spindle and is used to obtain the spindle speed. The encoder is connected to the PLC, and the PLC is connected to the servo motor;

[0015] A first button is connected to a servo controller of the servo motor and is used to send an enable signal to the servo controller;

[0016] The inching button is connected to the servo controller of the servo motor and is used to send an inching signal to the servo controller to control the servo motor to rotate independently.

[0017] Furthermore, the transmission assembly comprises:

[0018] Rotating shaft;

[0019] A second bevel gear, disposed at one end of the rotating shaft and meshing with the first bevel gear;

[0020] The transmission gear is arranged at the other end of the rotating shaft and meshes with the main gear on the transmission shaft.

[0021] Furthermore, the cigarette packaging machine driving device also includes: a knob connected to a servo controller of the servo motor, and used to send a speed signal to the servo controller to control the rotation speed of the servo motor when inching.

[0022] Furthermore, the transmission shaft is provided with:

[0023] A transparent paper transmission gear is connected with the transparent paper conveying mechanism and the transparent paper cutting mechanism through a gear set;

[0024] The wire-drawing cutting transmission gear is connected with the wire-drawing cutting mechanism.

[0025] Transmission principle:

[0026] The main motor 1 drives the main shaft 4A to rotate through the pulley 2, and transmits power to the strip box packaging machine and the strip box transparent paper packaging machine. The servo motor 81 transmits power to the main gear 3B on the transmission shaft 4B through the reducer 82 and the first bevel gear 83. The main gear 3B transmits power to the transmission shaft 4B through the tooth clutch 5. The transmission shaft 4B then drives the suction belt transmission gear, the transparent paper transmission gear, the wire cutting transmission gear and other transmission gears to transmit power to the wire cutting mechanism 71, the transparent paper conveying mechanism 72, the transparent paper cutting mechanism 73 and other mechanisms, driving the transparent paper and wire conveying cutting system of the small box transparent paper packaging machine to work.

[0027] Working principle:

[0028] When the cigarette packaging machine is working normally, the encoder 42A on the main shaft 4A obtains the rotation speed and phase of the main shaft 4A and sends the speed signal to the PLC. The PLC controls the rotation speed of the servo motor according to the rotation speed of the main shaft 4A to match the speed of the transmission shaft 4B with that of the main shaft 4A.

[0029] When semi-finished cigarettes (small boxes of cigarettes wrapped in transparent paper) need to be added, press the first button to send an enable signal to the servo controller of the servo motor, the servo motor stops, and the entire transparent paper and wire conveying and cutting system stops working. At this time, semi-finished cigarette packs can be added to the downstream equipment.

[0030] When it is necessary to maintain the small box transparent paper packaging machine (such as checking the cutting state of the transparent paper cutter), first press the first button to turn off the servo motor 81, and the entire transparent paper and wire conveying and cutting system stops working. Then press the inching button, the servo motor 81 rotates, and the servo motor 81 drives the transmission shaft 4B to rotate, and then drives the wire cutter, transparent paper conveying and cutting mechanism, transparent paper suction belt, etc. to rotate together, and the cut transparent paper tape with a wire is conveyed downward. The repairman can intuitively observe the cutting state of the transparent paper. When the cutting state is not good and needs to be adjusted, the repairman adjusts it. After the adjustment, the cutting state needs to be checked again, so continue to press the inching button 62, and the servo motor 81 continues to rotate and conveys a section of transparent paper tape with a wire. When the inspection is qualified, press the first button 61 to restore the servo motor 81 to match the main shaft 4A, start the machine, and resume normal production.

[0031] When the rotation speed of the servo motor 81 needs to be changed, it is done by rotating the knob 63 and then pressing the inching button 62 to achieve stepless speed regulation of the servo motor 81 .

[0032] Compared with the prior art, the utility model has the following beneficial effects:

[0033] (1) The driving device of the cigarette packaging machine provided by the utility model drives the transparent paper and wire conveying cutting system of the small box transparent paper packaging machine independently and separately, and uses buttons for cutting control, thereby avoiding the waste of a lot of time caused by frequent rotation of the equipment and the rejection of a large number of semi-finished cigarette packs, as well as the problem of high labor workload.

[0034] (2) After switching to independent drive, semi-finished cigarette packs can be added, avoiding the need to reprocess the semi-finished cigarette packs generated during maintenance (removing the outer transparent paper, adding the cigarette packs to the small pack conveying channel again, and wrapping them with transparent paper again), thereby reducing the waste of raw materials.

[0035] (3) The speed of the servo motor when it rotates alone can be adjusted, which solves the problem that maintenance personnel cannot turn the motor at high speed by themselves and cannot verify the state of the transparent paper cutting when running at high speed.

DETAILED DESCRIPTION

[0045] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0046] Example 1

[0047] After cigarettes are packed into small boxes, the downstream cigarette packaging machine consists of a small box transparent paper packaging machine, a strip box packaging machine and a strip box transparent paper packaging machine. Figure 3 As shown, the small box transparent paper packaging machine mainly includes a small box conveying mechanism 75, a wire cutting conveying mechanism 74, a wire cutting mechanism 71, a transparent paper conveying mechanism 72, a transparent paper cutting mechanism 73, a suction belt conveying mechanism, a beauty mechanism, etc. After the small box cigarette packs are transported to the work station through the small box conveying mechanism 75, the cigarette packs are packaged with transparent paper and wire, and then the cigarette packs are stacked and sent to the beauty mechanism, which are sealed by a soldering iron and finally sent to the downstream strip box packaging machine to be packaged into strips.

[0048] The downstream cigarette packing machine is driven by the cigarette packing machine drive device, such as Figure 4-7 As shown, the cigarette packaging machine driving device includes: a main motor 1, a main shaft 4A, a transmission shaft 4B, a PLC, a servo motor 81, an encoder 42A, a first button 61 and an inching button 62. The main motor 1 is installed on the base of the small box transparent paper packaging machine body, and is connected to the main shaft 4A through a pulley 2. The encoder 42A is installed on the main shaft 4A to obtain the speed and phase of the main shaft 4A. The end of the main shaft 4A is connected to the strip box packaging machine and the strip box transparent paper packaging machine to drive the strip box packaging machine and the strip box transparent paper packaging machine to operate. The main shaft 4A is provided with a clutch 41, and the clutch 41 can cut off the power of the strip box packaging machine and the strip box transparent paper packaging machine.

[0049] The output end of the servo motor 81 is provided with a reducer 82, and the output end of the reducer 82 is provided with a first bevel gear 83, and the first bevel gear 83 is connected to the transmission shaft 4B through a transmission assembly. The PLC is connected to the encoder 42A and the servo motor 81 respectively, and the encoder 42A sends the collected speed signal to the PLC, and the PLC controls the speed of the servo motor 81 according to the speed of the main shaft 4A, so that the speed of the transmission shaft 4B matches that of the main shaft 4A, and the synchronization of the transparent paper and the wire conveying and cutting system of the small box transparent paper packaging machine is realized.

[0050] Specifically, the transmission assembly includes: a rotating shaft 91, a second bevel gear 92 and a transmission gear 93. The second bevel gear 92 is arranged at one end of the rotating shaft 91, and the transmission gear 93 is arranged at the other end of the rotating shaft 91. The second bevel gear 92 is meshed with the first bevel gear 83, and the transmission gear 93 is meshed with the main gear 3B, thereby transmitting power to the transmission shaft 4B.

[0051] The transmission shaft 4B is provided with a suction belt transmission gear 3C, a transparent paper transmission gear 3C, and a wire cutting transmission gear 3D. The suction belt transmission gear 3C is connected to the suction belt conveying mechanism to transmit power to the suction belt conveying mechanism; the wire cutting transmission gear 3D is connected to the wire cutting mechanism 71 to drive the wire cutting mechanism 71 to operate; the transparent paper transmission gear 3C is connected to the transparent paper conveying mechanism 72 and the transparent paper cutting mechanism 73 through the gear group 3E to realize the conveying and cutting of transparent paper.

[0052] The PLC, the first button 61 and the inching button 62 are installed on the frame of the small box transparent paper packaging machine. The first button 61 is connected to the PLC. When the first button 61 is pressed, the power of the servo motor 81 is cut off, so that the entire transparent paper and wire conveying and cutting system stops working. At this time, semi-finished cigarette packs can be added to the downstream equipment. The inching button 62 is connected to the PLC to control the servo motor 81 to rotate independently, mainly used for independent control of the transparent paper and wire conveying and cutting system during maintenance.

[0053] like Figure 7 As shown, after pressing the first button 61, an enable signal is sent to the servo controller of the servo motor 81. After the servo controller receives the enable signal, the servo motor 81 stops and enters a standby state. At this time, the downstream equipment is in a normal operating state, and semi-finished cigarette packs can be directly added to the downstream, avoiding the need to reprocess the semi-finished cigarette packs generated during maintenance.

[0054] When the servo motor 81 is in standby mode, the inching button 62 is pressed, and the inching signal is sent to the servo controller, and the servo motor 81 rotates independently. At this time, its speed does not need to match the spindle 4A. When it rotates independently, it can drive the transparent paper and the wire conveying and cutting system to operate, so that the repair personnel can intuitively observe the cutting status of the transparent paper and the wire. When it is necessary to change the speed of the servo motor 81, it is only necessary to rotate the knob 63 and then press the inching button 62 to achieve stepless speed regulation of the servo motor 81.

[0055] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
