Description

Technical Field

[0001] The present application relates to the field of packaging equipment, and more specifically to a color mark sensing positioning mechanism. Background Art

[0002] The normal operation of the packaging machine's bag-making process requires the use of a color mark sensor to locate the bag's cutting position, complete the bag sealing and cutter positioning accurately.

[0003] Since the film placement position is too far from the sealing and cutting positions, cumulative errors will occur during operation, affecting the accuracy of the sealing and cutting positions. It is necessary to use a color mark sensor to determine the color mark position and accurately locate it. Traditional color mark sensors are fixed in one position. For various bags on the market, adjustments are complicated and not conducive to switching specifications or fine-tuning.

[0004] The styles of bags in the market are diverse, and customers have more and more requirements for one machine to produce multiple bags. The traditional fixing method is complicated to adjust, inconvenient to switch specifications, and inefficient. It cannot meet the market's product needs to solve the diverse packaging needs of most products. In view of this, the inventor has designed a color code sensing positioning mechanism that is easy to adjust and improves work efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a color mark sensing positioning mechanism, which has the advantage of facilitating the position adjustment of the color mark sensor according to different bag specifications, thereby improving work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a color mark sensing positioning mechanism, comprising a packaging machine bracket and a color mark sensor, wherein the packaging machine bracket is provided with racks extending along the movement direction of the bag on both inner sides of the color mark sensor, an adjustment device for adjusting the relative movement of the color mark sensor along the two racks is provided between the two racks, the adjustment device is provided with two gears respectively meshing with the two racks, the packaging machine bracket is provided with a screw rod parallel to the rack and threadedly connected to the adjustment device, the packaging machine bracket is provided with a driving motor, the screw rod and the shaft of the driving motor are provided with pulleys, and the two pulleys are connected by a transmission belt.

[0007] By adopting the above technical solution, when using the packaging machine, the position of the color mark sensor can be adjusted first according to the bag specifications, and the controller of the packaging machine bracket controls the driving motor to drive the pulley to operate, so that the screw rod rotates under the action of the two pulleys and the transmission belt, and the adjusting device moves along the extension direction of the rack under the action of the screw rod, gear and rack. When the color mark sensor is located at the specified position, the driving motor stops running, and the adjusting device is braked under the action of the screw rod, gear and rack; then the position of the color mark sensor between the two racks is adjusted by the adjusting device, and fixed after moving to the specified position.

[0008] In summary, the position of the color mark sensor in the direction of bag movement is adjusted by the driving motor, pulley, transmission belt, screw, gear and rack, and the position of the color mark sensor between the two racks is adjusted by the adjusting device, so as to facilitate the position adjustment of the color mark sensor according to different bag specifications and improve work efficiency.

[0009] The utility model is further configured as follows: the adjusting device includes two support plates that are fitted with two racks and used to install gears, a plurality of support columns arranged between the two support plates, a sliding shaft arranged between the two support plates and perpendicular to the racks, and a fixing bracket that is slidably arranged on the sliding shaft and used to fix the color mark sensor, the fixing bracket is provided with a tightening screw that is tightened against the sliding shaft, and the lead screw is threadedly connected to the corresponding support plate.

[0010] By adopting the above technical solution, when it is necessary to adjust the position of the color mark sensor through the adjusting device, the locking screw can be loosened, and then the fixed bracket can be moved along the sliding shaft. When the color mark sensor is located at the specified position, the fixed bracket can be locked on the sliding shaft by the locking screw; when the screw rod drives the adjusting device to move, the screw rod rotates and acts on the corresponding support plate, and the gear on the support plate interacts with the rack on the packaging machine bracket, so that the support plate drives the color mark sensor to move.

[0011] The utility model is further configured as follows: a rotating shaft for fixing the two gears is rotatably arranged between the two support plates.

[0012] By adopting the above technical solution, the two gears are fixed by the rotating shaft, so that the two gears can move synchronously, thereby making the movement of the color mark sensor more stable.

[0013] The utility model is further configured as follows: bearings that fit the rotating shaft are respectively arranged on the two support plates.

[0014] By adopting the above technical solution and setting the bearing, the friction between the support plate and the rotating shaft can be reduced, thereby reducing mechanical loss.

[0015] The utility model is further configured as follows: the driving motor is a stepping motor.

[0016] The utility model is further configured as follows: the pulley is a synchronous pulley, and the transmission belt is a synchronous belt meshed with the synchronous pulley.

[0017] By adopting the above technical solution, the setting of the synchronous pulley and the synchronous belt can effectively reduce the possibility of slipping of the synchronous pulley and the synchronous belt, thereby increasing the accuracy of the movement of the color mark sensor.

[0018] In summary, the utility model has the following advantages:

[0019] 1. The color mark sensor is adjusted in the direction of bag movement by driving the motor, pulley, transmission belt, screw, gear and rack, and the position of the color mark sensor between the two racks is adjusted by the adjusting device, so as to facilitate the position adjustment of the color mark sensor according to different bag specifications and improve work efficiency.

[0020] 2. When it is necessary to adjust the position of the color mark sensor through the adjustment device, the locking screw can be loosened, and then the fixed bracket can be moved along the sliding shaft. When the color mark sensor is at the specified position, the fixed bracket can be locked on the sliding shaft through the locking screw; when the screw drives the adjustment device to move, the screw rotates and acts on the corresponding support plate, and the gear on the support plate interacts with the rack on the packaging machine bracket, so that the support plate drives the color mark sensor to move.

[0021] 3. The two gears are fixed by a rotating shaft, which can make the two gears move synchronously, thereby making the movement of the color mark sensor more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] A color mark sensing positioning mechanism, such as Figure 1As shown, it includes a packaging machine bracket 1 and a color mark sensor 2. Racks 3 extending along the moving direction of the bag are fixed on both inner sides of the packaging machine bracket 1 located at the color mark sensor 2. An adjusting device for adjusting the relative movement of the color mark sensor 2 along the two racks 3 is installed between the two racks 3. Two gears 4 respectively meshing with the two racks 3 are rotatably installed on the adjusting device. A lead screw 6 parallel to the rack 3 and threadedly connected to the adjusting device is rotatably installed on the packaging machine bracket 1. A stepping motor 7 is fixed on the packaging machine bracket 1. Pulleys 8 are fixed on the shafts of the lead screw 6 and the stepping motor 7. The two pulleys 8 are connected by a transmission belt 9.

[0026] Furthermore, the pulley 8 is a synchronous pulley, and the drive belt 9 is a synchronous belt meshed with the synchronous pulley, which effectively reduces the possibility of slipping between the synchronous pulley and the synchronous belt, thereby increasing the accuracy of the movement of the color mark sensor 2.

[0027] like Figure 1 As shown, the adjustment device includes two support plates 10 that fit with the two racks 3 and are used to install the gear 4, two support columns fixed between the two support plates 10, a sliding shaft 11 fixed between the two support plates 10 and perpendicular to the rack 3, and a fixed bracket 12 that is slidably mounted on the sliding shaft 11 and is used to fix the color mark sensor 2. The fixed bracket 12 is threadedly connected with a tightening screw 13 that is tightly pressed against the sliding shaft 11, and the screw rod 6 is threadedly connected with the corresponding support plate 10. When it is necessary to adjust the position of the color mark sensor 2 through the adjustment device, the tightening screw 13 can be loosened, and then the fixed bracket 12 can be moved along the sliding shaft 11. When the color mark sensor 2 is located at the specified position, the fixed bracket 12 can be locked on the sliding shaft 11 by the tightening screw 13; when the screw rod 6 drives the adjustment device to move, the screw rod 6 rotates and acts on the corresponding support plate 10, and the gear 4 on the support plate 10 interacts with the rack 3 on the packaging machine bracket 1, so that the support plate 10 drives the color mark sensor 2 to move.

[0028] Furthermore, a rotating shaft 14 for fixing the two gears 4 is rotatably installed between the two support plates 10 . The two gears 4 are fixed by the rotating shaft 14 , so that the two gears 4 can move synchronously, thereby making the movement of the color mark sensor 2 more stable.

[0029] It is worth mentioning that bearings 15 that fit the rotating shaft 14 are respectively installed on the two support plates 10, which can reduce the friction between the support plates 10 and the rotating shaft 14, thereby reducing mechanical losses.

[0030] The working process and beneficial effects of the utility model are as follows: when using the packaging machine, the position of the color mark sensor 2 can be adjusted according to the bag specifications, and the controller of the packaging machine bracket 1 controls the driving motor to drive the pulley 8 to operate, so that the screw rod 6 rotates under the action of the two pulleys 8 and the transmission belt 9, and the adjusting device moves along the extension direction of the rack 3 under the action of the screw rod 6, the gear 4, and the rack 3. When the color mark sensor 2 is located at the specified position, the driving motor stops running, and the adjusting device is braked under the action of the screw rod 6, the gear 4, and the rack 3; then the color mark sensor 2 is adjusted between the two racks 3 through the adjusting device, and is fixed after moving to the specified position.

[0031] In summary, the position of the color mark sensor 2 in the direction of bag movement is adjusted through the driving motor, pulley 8, transmission belt 9, screw 6, gear 4, and rack 3, and the position of the color mark sensor 2 between the two racks 3 is adjusted through the adjustment device, thereby facilitating the position adjustment of the color mark sensor 2 according to different bag specifications and improving work efficiency.
