Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging film cutting device of packaging equipment. Background Art

[0002] Wet wipes can be used to wipe glasses, shoes and other items, and can also be used to wipe the face, mouth, hands and other parts of the body. The wet wipes packaging machine is used to fold the wet wipes, cut the wet wipes, add liquid inside and outside, make bags and seal them, count and batch number them, and output the finished products. The existing wet wipes packaging bags all adopt the four-side sealing method; during the bag making and sealing process, the packaging film needs to be cut for better packaging. However, in the actual use process, the existing cutting device for wet wipes packaging bags has poor stability of the packaging film when cutting the packaging film, which easily makes the packaging film wrinkled or poor in tightness, resulting in affecting the cutting quality of the packaging film;

[0003] In order to solve the above problems, a cutting device for wet wipes packaging bags with a publication number of "CN218084461U" is disclosed, comprising a device body, a frame connected to the surface of the device body, a top plate fixed on the top of the frame, a cylinder installed at the middle position of the bottom of the top plate, a piston rod connected to the output end of the cylinder, a mounting plate installed at the bottom end of the piston rod, springs installed on both sides of the bottom of the mounting plate, a pressing plate connected to the bottom end of the spring, a movable rod connected to the top of the pressing plate, by arranging the pressing plate, the spring and the movable rod, when the packaging film is cut by the cutting knife, the pressing plate will first contact the packaging film during the downward movement of the cutting knife, and the packaging film can be pressed and limited by the pressing plate, so that the packaging film can be flattened, thereby improving the cutting stability of the packaging film;

[0004] However, although the above-mentioned document can flatten and limit the packaging film by pressing the plate during the cutting process, when the packaging film has shifted during transportation, the existing device cannot correct the shifted packaging film, so that the packaging film will not be cut evenly when the cutting knife is cutting, and the problem of poor cutting accuracy of the packaging film still exists. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a packaging film cutting device of a packaging equipment with an automatic deviation correction function to improve the cutting accuracy of the packaging film in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging film cutting device of a packaging equipment, comprising a transmission mechanism and a cutter mechanism located at one end of the transmission mechanism, characterized in that: a first deviation correction mechanism is provided on both sides of the transmission mechanism, the first deviation correction mechanism can cause the cutting device to reciprocate along the width direction of the transmission mechanism, and a second deviation correction mechanism is provided between the transmission mechanism and the cutter mechanism, the second deviation correction mechanism can cause the cutter mechanism to reciprocate along the transmission direction of the transmission mechanism.

[0007] The above technical solution is adopted: through the setting of the first and second correcting mechanisms, when the packaging film is transported to the cutting device through other equipment of the packaging machine, when the packaging film is offset, by starting the first correcting mechanism, the cutting device can be pushed to reciprocate along the width direction of the transmission mechanism, thereby adapting to the offset packaging film and realizing the correction function. At the same time, the second correcting mechanism is started to prompt the cutter mechanism to reciprocate along the transmission direction of the transmission mechanism, so that it cooperates with the first correcting mechanism to realize the movement of the cutter mechanism, thereby ensuring that the size of the packaging film cut remains unchanged and improving the cutting accuracy of the packaging film.

[0008] The utility model is further configured as follows: the first deflection correcting mechanism includes mounting uprights respectively arranged on both sides of the transmission mechanism, a first deflection correcting motor connected to one side of the transmission mechanism and adjacent to the mounting uprights on the same side; one side of the transmission mechanism is provided with a fixed bracket installed on the output end of the first deflection correcting motor; a plurality of sliding blocks are respectively arranged on the bottom of the mounting uprights, and a first guide rail is provided between the corresponding sliding blocks on both sides; the first deflection correcting motor can push the cutting device to cause it to reciprocate along the first guide rail through the sliding block.

[0009] The above-mentioned technical solution is adopted: by installing a vertical plate and a first deflection correction motor, the installation vertical plate is preferably in an "L" shape, one side of which is fixedly connected to the two sides of the transmission mechanism, and the other side which is perpendicular to it is fixedly connected to the sliding block. In addition, a fixed bracket installed on the output end of the first deflection correction motor is provided on one side of the transmission mechanism to prevent the telescopic shaft from directly acting on the cutting device when the first deflection correction motor is output; when the first deflection correction motor is started, the telescopic shaft of the first deflection correction motor can push the cutting device to reciprocate along the first guide rail through the sliding block, thereby realizing the correction function of the first deflection correction mechanism.

[0010] A further configuration of the utility model is that a first sensor is provided at one end of the cutter mechanism away from the transmission mechanism, and the first sensor can detect the position where the packaging film is conveyed.

[0011] The above technical solution is adopted: by providing a first sensor at the end of the cutter mechanism away from the transmission mechanism, when the packaging film is conveyed to the cutting device and deviates, the first sensor can detect its position change and send a signal to the first correction motor, thereby starting the first correction motor and pushing the cutting device to move along the first guide rail, thereby realizing automatic correction function and improving production efficiency.

[0012] A further configuration of the utility model is that a plurality of passive sliding blocks are respectively arranged on both sides of the bottom of the cutter mechanism, second guide rails for reciprocating movement of the passive sliding blocks are respectively arranged on both sides of the connection between the cutter mechanism and the transmission mechanism, a third guide rail is arranged between the same ends of the two groups of second guide rails, and an active sliding block linked to the second deviation correction mechanism is slidably arranged on the third guide rail.

[0013] The above technical solution is adopted: through the setting of a passive sliding block, an active sliding block and the second and third guide rails, the active sliding block is linked with the second correcting mechanism. When the first correcting mechanism is in operation, in order to cooperate with the first correcting mechanism, the second correcting mechanism will be started at this time, and the active sliding block will be linked to rotate along the third guide rail. At this time, the passive sliding block will be driven to reciprocate along the second guide rail, thereby realizing the movement of the cutting knife mechanism, ensuring that the size of the packaging film cut remains unchanged, strengthening its correction function, and improving the cutting accuracy of the packaging film.

[0014] The utility model is further configured as follows: the second deviation correcting mechanism includes a mounting plate connected to both sides of the transmission mechanism, and a second deviation correcting motor connected to the bottom of the mounting plate; the mounting plate is provided with a through hole for the output shaft of the second deviation correcting motor to pass through; the output shaft of the second deviation correcting motor is sleeved with a first linkage block; one end of the first linkage block is connected to the output shaft, and the other end is extended toward the direction of the cutting mechanism and is provided with a connecting shaft, the connecting shaft is sleeved with a second linkage block, and the top of the second linkage block is connected to the active sliding block.

[0015] The above-mentioned technical scheme is adopted: through the setting of the mounting plate, the second correcting motor and the first linkage block, when the second correcting motor is started, since the second linkage block is sleeved on the other end of the first linkage block, and the top of the second linkage block is fixedly connected to the active sliding block, the output shaft of the second correcting motor starts to rotate and can drive the first linkage block to rotate, so that the second linkage block drives the active sliding block to reciprocate along the third guide rail, and at the same time, the third guide rail moves away from or close to the transmission mechanism relative to the second correcting motor, causing the passive sliding block to drive the cutter mechanism to reciprocate along the second guide rail, thereby realizing the correction of the cutter mechanism, ensuring that the size of the packaging film cut remains unchanged, strengthening its correction function, and improving the cutting accuracy of the packaging film.

[0016] A further configuration of the utility model is that a second sensor is provided on one side of the transmission mechanism and close to the cutter mechanism, and the second sensor can detect the position of the cutter mechanism.

[0017] The above technical solution is adopted: through the setting of the second sensor, when the packaging film is conveyed to the cutting device and the position is shifted, the first and second sensors will detect the shift and send signals to the first correcting mechanism and the second correcting mechanism respectively. When the first correcting mechanism completes the correction of the cutting device, at the same time, in order to ensure the size of the packaging film cut by the cutting mechanism, when the second correcting mechanism receives the signal detected by the second sensor, it will start the second correcting motor, and through the first and second linkage blocks and the active and passive sliding blocks, the cutting mechanism can reciprocate along the second guide rail, thereby realizing the correction of the cutting device, completing the automatic correction function of the second correcting mechanism, and improving the cutting accuracy of the packaging film.

[0019] The above technical solution is adopted: the operation of the transmission mechanism is realized through the setting of the outer plate, the rotating roller, the driving motor and the transmission belt. When the packaging film is cut by the cutting mechanism, it is transported to the next process through the transportation mechanism, thereby improving production efficiency.

[0020] A further configuration of the utility model is that the cutter mechanism includes a bottom plate, one of the rotating rollers is located at the bottom plate near the material output end of the cutter mechanism, and inner plates extending along the conveyor belt are respectively provided on both sides of the rotating roller, a fourth guide rail is provided on the side of the inner plate close to the outer plate, at least one fixed slider is fixedly provided on the side of the outer plate close to the inner plate, and a sliding groove for reciprocating movement of the fourth guide rail is provided on the side of the fixed slider away from the side plate.

[0021] The above technical solution is adopted: when the second deviation correction motor is started to make the cutter mechanism reciprocate along the second guide rail, through the arrangement of the bottom plate, the inner plate, the fourth guide rail and the fixed slider, and at the same time one of the rotating rollers is arranged at the bottom plate close to the material output end of the cutter mechanism, at this time the inner plate can move along the slide groove on the fixed slider through the fourth guide rail, so that when the cutter mechanism is moving, the transmission mechanism will not hinder the deviation correction of the cutter mechanism, thereby improving the deviation correction effect while ensuring the use effect.

[0022] A further configuration of the utility model is that at least two rotating rollers are fixedly arranged between the inner side plates.

[0023] The above technical solution is adopted: at least two rotating rollers are fixedly arranged between the inner plates, so that when the inner plate moves along the slide groove on the fixed slider through the fourth guide rail, the rotating roller can be driven to move together, ensuring that the conveyor belt can be kept flat during the movement of the cutting mechanism without wrinkles, which affects the transportation of the packaging film.

[0024] The utility model is further configured as follows: the cutter mechanism comprises a cylinder, a cutter, a base plate and a workbench, the cutter is connected to the output end of the cylinder, the base plate is connected to the transmission mechanism, one end of the workbench is connected to the surface of the base plate, and the other end is connected to the output end of the cylinder, the workbench is provided with a cutting hole from the top for the cutter to move vertically back and forth, and an opening is provided in the middle of the workbench for materials to enter and exit, and the opening is communicated with the cutting hole.
