Description

Technical Field

[0001] The utility model particularly relates to a feeding deviation correction and adjustment device for bag making equipment. Background Art

[0002] Bag making machine is a kind of mechanical equipment specially used to make various types of bags. Its working principle is mainly based on the continuous conveying, ironing, cutting, sealing, bagging and other processes of materials such as plastic film or paper. First, the raw materials are fed into the machine through the unwinding mechanism, and then delivered to each working part in turn through the traction mechanism for ironing, cutting, sealing, bagging, etc. During the whole process, various parts of the bag making machine work together to ensure the production efficiency and quality of the bags.

[0003] Then, during the operation of the bag making machine, the bag material will deviate left and right and the tension level will be inconsistent, thus affecting the hot welding position of the handle.

[0004] In order to solve the above technical problems, a Chinese utility model patent with publication number "CN218558126U" discloses a feeding correction and adjustment mechanism of a packaging bag forming machine, including a color mark sensor, a feeding rack, a substrate sensor, a bag feeding servo motor, a first horizontal drive assembly, a second horizontal drive assembly, a movable seat, and an active roller group. Among them, each group of substrate sensors is respectively linked to a first mounting seat and a second mounting seat, and also includes a second screw rod (two sections of thread, and the spiral direction is opposite) that is simultaneously threadedly linked to the first mounting seat and the second mounting seat. Finally, the rotation of the second screw rod is controlled by the second adjustment motor, so as to realize the monitoring of the left and right deflection of the bag material, and further the substrate sensor controls the first horizontal drive assembly and the second horizontal drive assembly to drive the movable seat and the feeder to move.

[0005] The above-mentioned feeding deviation correction adjustment mechanism has the following defects:

[0006] (I) The feed deflection correction adjustment mechanism can only be used to monitor the left and right deviation of the bag material, and the deviation is based on the condition that the lateral dimension of the bag material will not change. However, in the actual production process, the bag material will stretch or shrink to different degrees, and the stretch or shrinkage is irregular, resulting in changes in the lateral dimension of the bag material. Therefore, the centerline position of the bag material is always changing, and the two sets of substrate sensors of the feed deflection correction adjustment mechanism are synchronously moved closer or farther away from each other, and the overall position cannot be adjusted according to the centerline of the bag material. In this way, even if the feed deflection correction adjustment mechanism is used to correct the deviation, it will cause the bag mouth to be uneven after sewing, which seriously affects the quality of the bag body.

[0007] (ii) The feed deviation correction adjustment mechanism is not actually able to effectively solve the problem of inaccurate handle welding position. In the actual processing process, when the handle is welded on the bag body, it is very easy for the handle to be not centered (the handle as a whole is biased toward the side of the bag body), which seriously affects the quality of the bag body. The feed deviation correction adjustment mechanism can only adjust the left and right offset of the bag material, and this adjustment will only change whether the handle is welded on the bag body toward the bag opening or away from the bag opening, and cannot solve the problem of "the handle is not centered (the handle as a whole is biased toward one side of the bag body)" mentioned above. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a feeding deviation correction and adjustment device for bag making equipment in view of the deficiencies of the above-mentioned prior art, which increases the adaptive adjustment to the lateral size change of the bag material on the basis of maintaining the original deviation correction function, so that the processed bag mouth will not appear uneven.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding correction adjustment device of a bag making equipment comprises a frame, a feeding frame, and a horizontal adjustment mechanism, wherein the feeding frame is linked with the frame through the horizontal adjustment mechanism, the feeding frame is provided with a traction roller group and a correction electric eye tracking component, the correction electric eye tracking component is distributed at the discharge end of the feeding frame, the correction electric eye tracking component comprises a first motor, a first screw rod linked with the output end of the first motor, the first screw rod is provided with a left thread segment and a right thread segment with opposite spiral directions, the first screw rod is linked with a first mounting seat through the left thread segment, and the first screw rod is linked with a second mounting seat through the right thread segment, a group of substrate sensors are respectively provided on the first mounting seat and the second mounting seat, characterized in that: the correction electric eye tracking component also comprises a transverse adjustment frame, a second motor, and a second screw rod, the body of the first motor is mounted on the transverse adjustment frame, the body of the second motor is fixed on the transverse adjustment frame, one end of the second screw rod is hinged with the transverse adjustment frame, the middle thread is linked with a first nut, and the other end is linked with the output end of the second motor, and the first nut is fixedly mounted on the feeding frame.

[0010] By adopting the above technical solution, it is possible to increase the adaptive adjustment of the lateral size change of the bag material on the basis of maintaining the original correction function. By setting the lateral adjustment frame, the second motor and the second screw rod, the lateral position of the first motor can be adjusted, thereby adjusting the position of the substrate sensor, and realizing accurate tracking and monitoring of the bag material to adapt to the extension and contraction of the width direction of the bag material. The horizontal adjustment mechanism corrects the bag material based on the signal monitored by the substrate sensor. Regardless of whether the bag material is tilted left and right as a whole, or the bag material is extended or contracted left and right, the bag material can be corrected, so that the processed bag mouth will not appear uneven. At the same time, by setting the first slide rail, the first slider, the second slider, the third slider and the corresponding slide rail, the first mounting seat and the second mounting seat can slide smoothly, thereby improving the stability and reliability of the entire correction electric eye tracking assembly.

[0011] The feeding deviation correction and adjustment device of the above-mentioned bag making equipment can be further configured as follows: a first slide rail is installed on the side of the transverse adjustment frame, the first slide rail is slidably matched with a first slider, and the first slider is fixedly installed on the feeding frame; the first mounting seat is linked with a second slider, the second slider is slidably matched with a second slide rail installed below the transverse adjustment frame, the second mounting seat is linked with a third slider, and the third slider is slidably matched with a third slide rail installed below the transverse adjustment frame.

[0012] By adopting the above technical solution, the working reliability of the deviation-correcting electric eye tracking component and the stability of the overall structure are improved, and the deviation-correcting effect is better.

[0013] The feed deviation correction and adjustment device of the bag making equipment can be further configured as follows: a group of handle sensors are respectively provided on the first mounting seat and the second mounting seat, and the two groups of handle sensors are distributed between the two groups of substrate sensors.

[0014] By adopting the above technical solution, the handle can be further improved by setting the handle sensor. In the actual working process, the two sets of handle sensors are used to monitor the hot welding of the handle. Once it is detected that the handle is not hot welded successfully, the bag making machine as a whole needs to be stopped for inspection until the handle is hot welded successfully before the next step can be carried out; and the two sets of base material sensors monitor the two sides of the bag material to monitor whether the bag material needs to be corrected.

[0015] The feeding deviation correction and adjustment device of the above-mentioned bag making equipment can be further configured as follows: the feeding rack is provided with a stepping roller assembly at the feeding end, and a tracking electric eye is provided above the stepping roller assembly; the stepping roller assembly includes an active stepping roller whose two ends are respectively hinged to the feeding rack, one end of the active stepping roller is linked to a pulley group, the end of the pulley group located away from the active stepping roller is linked to a third motor, the other end of the active stepping roller is gear-engaged with a driven stepping roller, and the bag material passes between the active stepping roller and the driven stepping roller.

[0016] By adopting the above technical solution, the precise adjustment of the hot welding position of the handle can be added on the basis of maintaining the original deviation correction function, thereby solving the problem of the handle not being centered. By setting a stepping roller assembly and a tracking electric eye at the feeding end of the feeding rack, the precise conveying and tracking of the bag material can be achieved. When the third motor is started, the active stepping roller is driven to rotate through the pulley group, and then the driven stepping roller is driven to rotate, so that the bag material passes between the two rollers. The tracking electric eye is located above the stepping roller assembly and is used to monitor the position of the bag material in real time. According to the monitoring results, the speed of the third motor is reasonably controlled to realize the control of the stepping roller assembly to adjust the conveying speed and position of the bag material. Since the stepping roller assembly can accurately convey and position the bag material, it can ensure the accurate position of the hot welding of the handle on the bag body, and ensure that the handle is always located in the center of the bag body.

[0017] The feeding deviation correction and adjustment device of the above-mentioned bag making equipment can be further configured as follows: the feeding rack is also provided with a floating roller assembly at the feeding end, the floating roller assembly includes a first floating roller and a second floating roller which are relatively distributed up and down, the first floating roller has floating blocks hinged at both ends respectively, the lower end of the floating block is hinged to the second floating roller, the middle part of the floating block is linked with a fourth slider, the fourth slider is slidably connected with a fourth slide rail fixedly installed on the feeding rack, the fourth slide rail is arranged parallel to the bag material transportation direction, the floating block is also linked with a cylinder, and the cylinder can drive the floating block to reciprocate along the axis of the fourth slide rail.

[0018] The above technical solution not only increases the ability to adjust the bag material tension, but also enables the precise adjustment of the handle hot welding position. The setting of the floating roller assembly enables the first floating roller and the second floating roller to be adaptively adjusted according to the change of the bag material tension, ensuring that the bag material maintains a stable tension state during the conveying process. The first floating roller and the second floating roller can also float left and right according to the handle signal monitored by the tracking electric eye, so that the interval between the handle to be hot welded and the handle that was hot welded last time meets the requirements, further realizing the precise adjustment of the handle hot welding position. The fourth slide rail and the fourth slider enable the floating block to slide smoothly, improving the stability and reliability of the floating roller assembly.

[0019] The feed deviation correction and adjustment device of the bag making equipment can be further configured as follows: a group of auxiliary traction rollers hinged to the feed frame are provided on one side of the floating roller assembly, and the auxiliary traction rollers are distributed between the first floating roller and the second floating roller.

[0020] By adopting the above technical solution, the bag material is pulled by the traction roller group to first pass through the first floating roller, then pass through the auxiliary traction roller, and finally pass through the second floating roller. Therefore, the bag material is in the form of multiple windings after passing through the floating roller assembly and the auxiliary traction roller, which increases the adjustment capacity of the floating roller assembly and can adjust the bag material within a larger range so that the handle can be centered.

[0021] The feeding deviation correction and adjustment device of the bag making equipment can be further configured as follows: the feeding end of the feeding frame is provided with two groups of stepping roller assemblies, the two groups of stepping roller assemblies are arranged opposite to each other up and down, and the floating roller assembly is distributed between the two groups of stepping roller assemblies.

[0022] The adoption of the above technical solution can significantly improve the conveying stability and correction accuracy of the bag materials, enhance the adaptability to bags of different materials and thicknesses, and ensure uniform tension.

[0023] The feeding deviation correction adjustment device of the above-mentioned bag making equipment can be further configured as: the horizontal adjustment mechanism includes a fourth motor whose main body is fixed on the frame, the output end of the fourth motor is linked to a third screw rod, the third screw rod is threadedly connected to a second nut, the second nut is linked to the feeding rack, and a fifth slider is linked under the feeding rack, the fifth slider is slidably connected to a fifth slide rail, the fifth slide rail is fixedly installed on the frame, and the fifth slide rail is distributed perpendicular to the bag material transportation direction.

[0024] By adopting the above technical solution, based on the real-time monitoring of the bag material by the substrate sensor, the fourth motor controls the rotation of the third screw rod to change the position relationship of the second nut, that is, change the lateral position of the bag material to achieve deviation correction.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 6 The feeding deviation correction and adjustment device of the bag making equipment shown includes a frame, a feeding frame a, and a horizontal adjustment mechanism b. The feeding frame a is linked with the frame through the horizontal adjustment mechanism b. The feeding frame a is provided with a traction roller group. The feeding end of the feeding frame a is provided with two groups of stepping roller assemblies c and a tracking electric eye f. The two groups of stepping roller assemblies c are arranged opposite to each other up and down, and a floating roller assembly d is provided between the two groups of stepping roller assemblies c. The discharging end of the feeding frame a is provided with a deviation correction electric eye tracking assembly e.

[0035] The deflection correction electric eye tracking assembly e includes a first motor e1, a first screw rod e2 linked to the output end of the first motor e1, a left thread section and a right thread section with opposite spiral directions are provided on the first screw rod e2, the first screw rod e2 is linked to a first mounting seat e3 through the left thread section, and the first screw rod e2 is linked to a second mounting seat e4 through the right thread section, and a group of substrate sensors e5 are respectively provided on the first mounting seat e3 and the second mounting seat e4, and the deflection correction electric eye tracking assembly e also includes a transverse adjustment frame e6, a second motor e7, and a second screw rod e8, the body of the first motor e1 is installed on the transverse adjustment frame e6, the body of the second motor e7 is fixed on the transverse adjustment frame e6, one end of the second screw rod e8 is hinged to the transverse adjustment frame e6, the middle part is linked to the first nut e9, and the other end is linked to the output end of the second motor e7, and the first nut e9 is fixedly installed on the feeding frame a. On the basis of maintaining the original deflection correction function, the adaptive adjustment to the transverse size change of the bag material can be added. By setting the lateral adjustment frame e6, the second motor e7 and the second screw rod e8, the lateral position of the first motor e1 can be adjusted, thereby adjusting the position of the substrate sensor e5, and realizing accurate tracking and monitoring of the bag material to adapt to the extension and contraction of the width direction of the bag material. The horizontal adjustment mechanism b corrects the bag material based on the monitored signal of the substrate sensor e5. Whether the bag material is skewed left and right as a whole, or the bag material is extended or contracted left and right, the bag material can be corrected, so that the processed bag mouth will not be uneven. At the same time, by setting the first slide rail, the first slider, the second slider, the third slider and the corresponding slide rail, the first mounting seat e3 and the second mounting seat e4 can slide smoothly, thereby improving the stability and reliability of the entire correction electric eye tracking component e.

[0036] The side of the transverse adjustment frame e6 is equipped with a first slide rail e10, which is slidably matched with a first slider e11, which is fixedly mounted on the feeding frame a; the first mounting seat e3 is linked with a second slider e12, which is slidably matched with a second slide rail e13 mounted below the transverse adjustment frame e6; the second mounting seat e4 is linked with a third slider e14, which is slidably matched with a third slide rail e15 mounted below the transverse adjustment frame e6. The working reliability of the deviation correction electric eye tracking assembly e and the stability of the overall structure are improved, and the deviation correction effect is better.

[0037] A set of handle sensors e16 are respectively provided on the first mounting seat e3 and the second mounting seat e4, and the two sets of handle sensors e16 are distributed between the two sets of substrate sensors e5. By providing the handle sensors e16, the handle can be further improved. In the actual working process, the two sets of handle sensors e16 are used to monitor the hot welding of the handle. Once it is detected that the hot welding of the handle is not successful, the bag making machine as a whole needs to be stopped for inspection until the hot welding of the handle is successful before the next step can be carried out; and the two sets of substrate sensors e5 monitor both sides of the bag material to monitor whether the bag material needs to be corrected.

[0038] In summary, during the transportation of the bag material, the handle sensor e16 monitors the hot welding of the handle. Once it is found that the handle is not successfully hot welded, it will send a shutdown or maintenance signal; if the handle is successfully hot welded, the base material sensor e5 will adjust its position under the drive of the first motor e1, the second motor e7, the first screw rod e2, and the second screw rod e8 to adapt to various changes in the bag material. Then the horizontal adjustment mechanism b adjusts the bag material according to the monitoring signal of the base material sensor e5, so that the center line of the bag material is always on the correct transportation track, so that the processed bag mouth can avoid unevenness.

[0039] The stepping roller assembly c includes an active stepping roller c1, whose two ends are respectively hinged on the feeding frame a. One end of the active stepping roller c1 is linked with a pulley group c2. The pulley group c2 is located at the end far away from the active stepping roller c1 and is linked with a third motor c3. The other end of the active stepping roller c1 is gear-engaged with a driven stepping roller c4, and the bag material passes between the active stepping roller c1 and the driven stepping roller c4. On the basis of maintaining the original deviation correction function, the precise adjustment of the hot welding position of the handle can be added to solve the problem of the handle not being centered. By arranging the stepping roller assembly c and the tracking electric eye f at the feeding end of the feeding frame a, the accurate conveying and tracking of the bag material can be achieved. When the third motor c3 is started, the active stepping roller c1 is driven to rotate through the pulley group c2, and then the driven stepping roller c4 is driven to rotate, so that the bag material passes between the two rollers. The tracking electric eye f is located above the stepping roller assembly c and is used to monitor the position of the bag material in real time. According to the monitoring results, the speed of the third motor c3 is reasonably controlled to control the stepping roller assembly c to adjust the conveying speed and position of the bag material. Since the stepping roller assembly c can accurately convey and position the bag material, the handle can be accurately welded on the bag body and the handle can always be located at the center of the bag body.

[0040] The floating roller assembly d includes a first floating roller d1 and a second floating roller d2 which are relatively distributed up and down. The first floating roller d1 is hinged with floating blocks d3 at both ends. The lower end of the floating block d3 is hinged with the second floating roller d2. The middle of the floating block d3 is linked with a fourth slider d4. The fourth slider d4 is slidably connected with a fourth slide rail d5 fixedly installed on the feeding rack a. The fourth slide rail d5 is arranged parallel to the bag material transportation direction. The floating block d3 is also linked with a cylinder d6. The cylinder d6 can drive the floating block d3 to reciprocate along the axis of the fourth slide rail d5. In addition to increasing the ability to adjust the bag material tension, it can also further achieve precise adjustment of the handle hot welding position. The setting of the floating roller assembly d enables the first floating roller d1 and the second floating roller d2 to be adaptively adjusted according to the change of the tension of the bag material, ensuring that the bag material maintains a stable tension state during the conveying process. The first floating roller d1 and the second floating roller d2 can also float left and right according to the handle signal monitored by the tracking electric eye f, so that the interval between the handle to be hot-welded and the handle that has been hot-welded last time meets the requirements, further realizing the precise adjustment of the hot-welding position of the handle. The fourth slide rail d5 and the fourth slider d4 enable the floating block d3 to slide smoothly, improving the stability and reliability of the floating roller assembly d.

[0041] One side of the floating roller assembly d is provided with a group of auxiliary traction rollers d7 hinged on the feeding frame a, and the auxiliary traction rollers d7 are distributed between the first floating roller d1 and the second floating roller d2. The bag material is pulled by the traction roller group to first pass through the first floating roller d1, then pass through the auxiliary traction roller d7, and finally pass through the second floating roller d2. Therefore, the bag material is wound multiple times after passing through the floating roller assembly d and the auxiliary traction roller d7, which increases the adjustment capacity of the floating roller assembly d and can adjust the bag material in a larger range so that the handle can be centered.

[0042] The horizontal adjustment mechanism b includes a fourth motor b1 whose main body is fixed on the frame, and the output end of the fourth motor b1 is linked with a third screw rod b2, and the third screw rod b2 is threadedly connected with a second nut b3, and the second nut b3 is linked with the feeding rack a, and the feeding rack a is linked with a fifth slider b4 below, and the fifth slider b4 is slidably connected with a fifth slide rail b5, and the fifth slide rail b5 is fixedly installed on the frame, and the fifth slide rail b5 is distributed perpendicular to the transport direction of the bag material. According to the real-time monitoring of the bag material by the substrate sensor e5, the fourth motor b1 controls the rotation of the third screw rod b2, thereby changing the position relationship of the second nut b3, that is, changing the lateral position of the bag material, to achieve deviation correction.
