An adaptive correction box sealing machine

Abstract

This invention discloses an adaptive correction carton sealing machine, relating to the field of packaging equipment technology. The invention includes a conveyor with an electric lifting frame at its top. A sealing mechanism body is fixedly mounted on the top of the electric lifting frame. A sealing platform is fixedly mounted inside the conveyor, and a first mounting hole is provided on the top of the sealing platform. A first electric lifting platform is fixedly mounted inside the first mounting hole. This invention uses correction conveyor belts, causing the two side correction conveyor belts to rotate slowly in opposite directions. This causes the hook strips on the sides of the correction conveyor belts to engage with the sides of the carton, thereby rotating the carton back to its correct position. When the correction conveyor belts stop rotating, the correction beams on both sides drive the stationary correction conveyor belts to clamp and limit the carton, completing the correction of the carton's alignment. By using the counter-rotating correction conveyor belts to pre-rotate the carton, direct rigid contact between the correction beams on both sides and the sides of the carton is avoided, preventing damage to the sides of the carton.

Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically to an adaptive correction carton sealing machine. Background Technology

[0002] Carton sealing machines are mainly used for sealing and packaging cartons. They can be used as standalone machines or in conjunction with production lines. They can operate on a single carton or be integrated with carton forming and opening machines, carton packing machines, labeling machines, strapping machines, pallet stacking machines, conveyors, and other equipment to form a packaging production line. They are essential equipment for packaging production line operations. Carton sealing machines are mainly divided into: automatic cap-opening and sealing machine series, pneumatic adjustment sealing machine series, automatic sealing machine series, corner sealing machine series, four-corner sealing machine, I-beam sealing machine, etc. Sealing methods can be divided into: top and bottom drive, left and right drive, side, corner, etc. Transparent tape and kraft paper materials are generally used.

[0003] Existing carton sealing machines require the carton to be aligned before sealing. This is often achieved by using two horizontally reversible centering beams as a correction mechanism. However, this correction mechanism causes the carton to come into rigid contact with the centering beams, which in turn causes damage to the sides of the carton due to compression. Additionally, the bottom of the carton will wear out when it rotates. Therefore, an adaptive correction carton sealing machine is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing carton sealing machines often use two horizontally reversible centering beams as a correction mechanism to correct the orientation of the carton before sealing. However, this correction mechanism causes the carton to come into rigid contact with the centering beams, which leads to damage to the sides of the carton due to compression. At the same time, the bottom of the carton will wear out when it rotates. This invention provides an adaptive correction carton sealing machine.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] An adaptive carton sealing machine includes a conveyor, an electric lifting frame on top of the conveyor, a sealing mechanism body fixedly mounted on top of the electric lifting frame, a sealing platform fixedly mounted inside the conveyor, a first assembly hole on top of the sealing platform, a first electric lifting platform fixedly mounted inside the first assembly hole, an electric turntable fixedly mounted on the telescopic end of the first electric lifting platform with its extension facing upwards, two suspension frames fixedly mounted on both sides of the conveyor, a horizontally arranged first electric push rod fixedly mounted on top of each suspension frame, a common correction beam fixedly mounted on the telescopic ends of the two first electric push rods on the same side, the two correction beams symmetrically arranged and slidably mounted on top of the sealing platform, and support platforms on both sides of the conveyor, each support platform having a correction mechanism for correcting the carton's alignment on its top.

[0007] Furthermore, the correction mechanism includes an electric lifting rod disposed on the top of the support platform. The telescopic end of the electric lifting rod is vertically upward and fixedly mounted with a lifting slide. Two horizontally arranged horizontal slide rods are slidably mounted on each lifting slide. A common correction beam is fixedly installed between the two horizontal slide rods located on the same side. A horizontally arranged second electric push rod is fixedly installed inside each lifting slide. The telescopic end of the second electric push rod located at the same location is fixedly installed on the side wall of the correction beam. The two correction beams are symmetrically arranged on the top of the conveyor.

[0008] Furthermore, each of the correction beams is fixedly installed with a correction conveyor belt, and each of the correction conveyor belts has multiple evenly distributed hanging strips fixedly installed on its sidewalls.

[0009] Furthermore, each of the support platforms is fixedly mounted with a linear guide rail, and each of the linear guide rails is driven to mount an electric slider. The two electric lifting rods are respectively fixedly mounted on the top of the two electric sliders.

[0010] Furthermore, a height measuring frame is fixedly installed on the top of each of the two horizontal sliding rods located above, and the two height measuring frames are symmetrically distributed and located on the top of the two correction beams respectively.

[0011] Furthermore, a correction platform is fixedly installed inside the conveyor, and a second assembly hole is opened inside the correction platform. A second electric lifting platform is fixedly installed inside the second assembly hole, and a correction turntable is rotatably installed on the top of the second electric lifting platform.

[0012] Furthermore, a measuring gantry is fixedly installed at the end of the conveyor away from the electric lifting frame. A first ultrasonic measuring instrument is fixedly installed on the top of the measuring gantry. Inclined frames are fixedly installed on both sides of the top of the measuring gantry. A second ultrasonic measuring instrument is fixedly installed on one side of each inclined frame. Both the first and second ultrasonic measuring instruments face the conveyor.

[0013] Furthermore, a feeding conveyor belt is fixedly installed inside each of the correction beams.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, by setting up a correction conveyor belt, causes the correction conveyor belts on both sides to slowly rotate in opposite directions when the correction beam moves toward the carton. This causes the hook strips on the sides of the correction conveyor belt to engage with the side of the carton, thereby driving the carton to rotate back to the correct position. When the correction conveyor belt stops rotating, the correction beams on both sides drive the stationary correction conveyor belt to clamp and limit the carton, thus completing the correction of the carton. By causing the carton to rotate back in advance through the reverse rotation of the correction conveyor belt, the direct rigid contact between the correction beams on both sides and the side of the carton is avoided, thus preventing the problem of damage to the side of the carton.

[0016] 2. By setting up electric sliders and linear guides, after the carton is straightened and clamped and limited by the correction beam, the electric sliders on both sides will drive the electric lifting rod to move the top correction beam along the linear guide, so that the carton is conveyed to the bottom of the sealing mechanism body while being limited. When the carton is sent to the first electric lifting platform, the correction mechanism will release the carton and reset it. The correction beams on both sides will take over from the correction beam to limit the carton and prevent the carton from shifting position again during the conveying process after being corrected.

[0017] 3. By setting up a second electric lifting platform, after the carton is conveyed to the top of the correction platform by the conveyor, the second electric lifting platform inside the second assembly hole will drive the correction turntable to lift up and lift the carton a short distance. After that, when the correction mechanism corrects the carton, the carton will rotate. The correction turntable separates the bottom of the carton from the second electric lifting platform and the correction platform, so that the carton can rotate smoothly without causing wear on the bottom.

[0018] 4. By setting up a first ultrasonic measuring instrument and a second ultrasonic measuring instrument, when the carton is sent to one end of the conveyor, the carton will pass through the measuring gantry and be scanned by the first ultrasonic measuring instrument directly above and the second ultrasonic measuring instruments diagonally above on both sides. This allows the external structure of the carton to be detected, and the approximate data of the current length, width, height and orientation of the carton to be obtained. This provides a reference for the subsequent position adjustment of the sealing mechanism and the operation of the correction mechanism. Attached Figure Description

Therefore, they should not be construed as limiting the present invention.

[0032] like Figures 1 to 8 As shown, an adaptive correction box sealing machine includes a conveyor 1, such as... Figure 1 As shown, an electric lifting frame 2 is installed on the top of the conveyor 1, and a sealing mechanism body 3 is fixedly installed on the top of the electric lifting frame 2. Figure 3 As shown, a sealing platform 4 is fixedly installed inside the conveyor 1. A first assembly hole is provided on the top of the sealing platform 4. A first electric lifting platform 5 is fixedly installed inside the first assembly hole. The telescopic end of the first electric lifting platform 5 faces vertically upwards and is fixedly fitted with an electric turntable 6. Figure 4 As shown, two suspension brackets 7 are fixedly installed on both sides of the conveyor 1. A horizontally arranged first electric push rod 8 is fixedly installed on the top of each suspension bracket 7. The telescopic ends of the two first electric push rods 8 located on the same side are fixedly installed with the same correction beam 9. The two correction beams 9 are symmetrically arranged and slidably installed on the top of the sealing platform 4. Figure 2As shown, support platforms 10 are provided on both sides of the conveyor 1, and each support platform 10 is equipped with a correction mechanism for correcting the alignment of the carton. Specifically, when this adaptive correction carton sealing machine is in use, the carton to be sealed is placed on one end of the conveyor 1, and the conveyor 1 transports the carton. When the carton is transported between the two correction mechanisms, the carton is corrected in orientation. Then the carton continues to be transported to the bottom of the sealing mechanism body 3. At this time, the carton is located on the top of the sealing platform 4, and the first electric push rods 8 on both sides... The drive correction beam 9 slides on the sealing table 4 until it contacts the carton, thereby performing secondary correction and limiting on the carton. Then, the electric lifting frame 2 drives the sealing mechanism body 3 to descend and seal the carton. Then, the correction beam 9 releases the carton, and the first electric lifting platform 5 drives the electric turntable 6 to rise in the first assembly hole until it contacts the bottom of the carton and lifts the carton. At this time, the electric turntable 6 drives the carton to rotate and change the position of the carton. Then, the sealing mechanism body 3 descends again to seal the carton a second time, completing the carton sealing process.

[0033] like Figure 5 As shown, the correction mechanism includes an electric lifting rod 11 mounted on the top of the support platform 10. The telescopic end of the electric lifting rod 11 is vertically upward and fixedly mounted with a lifting slide 12. Two horizontally arranged horizontal slide rods 13 are slidably mounted on each lifting slide 12. A common correction beam 14 is fixedly mounted between the two horizontal slide rods 13 on the same side. A horizontally arranged second electric push rod 15 is fixedly mounted inside each lifting slide 12. The telescopic end of the second electric push rod 15 located at the same position is fixedly mounted on the side wall of the correction beam 14. Two correction beams 14 are symmetrically arranged on the top of the conveyor 1. Specifically, by setting a correction mechanism, when the carton is transported between the two correction mechanisms, the electric lifting rod 11 will drive the two correction beams 14 to rise up and down to match the current height of the carton. Then, the second electric push rods 15 on both sides will drive the two correction beams 14 to move towards the carton until they contact the carton. Then, the carton will automatically return to the correct position under the push of the correction beams 14, completing the automatic correction and preventing the carton from being misaligned with the sealing mechanism body 3, which would affect the accuracy of sealing.

[0034] like Figure 6 As shown, each of the correction beams 14 has a correction conveyor belt 16 fixedly installed inside, such as... Figure 7As shown, multiple evenly distributed hanging strips 20 are fixedly installed on the side walls of the correction conveyor belt 16. In this embodiment, the correction conveyor belt 16 is fixed inside the correction beam 14. The correction conveyor belt 16 is divided into a transmission toothed belt and a set of transmission toothed rollers. The transmission toothed rollers are rotatably installed inside the correction beam 14. The transmission toothed belt meshes with the transmission toothed rollers and is tensioned and sleeved on the transmission toothed rollers. It is driven by a transmission motor. The hanging strips 20 are vertically arranged and evenly distributed on the outer peripheral side walls of the transmission toothed belt. Specifically, by setting the correction conveyor belt 16, when the correction beam 14 moves towards the carton, the correction conveyor belts 16 on both sides will slowly rotate in opposite directions. When the carton is offset from the sealing mechanism body 3, the correction conveyor belt 16 will first contact the side of the carton, so that the hook strip 20 on the side of the correction conveyor belt 16 will be locked on the side of the carton, thereby driving the carton to rotate. When the carton returns to the correct position, the side wall of the carton will be parallel to the correction conveyor belt 16. At this time, the correction conveyor belt 16 stops rotating, and the correction beams 14 on both sides drive the stationary correction conveyor belt 16 to clamp and limit the carton, completing the correction of the carton. The correction conveyor belt 16 rotates in the opposite direction to drive the carton to rotate in advance, avoiding direct rigid contact between the correction beams 14 on both sides and the side of the carton, thus preventing the problem of damage to the side of the carton.

[0035] like Figure 2 As shown, linear guide rails 18 are fixedly installed on the top of the support platform 10, such as... Figure 5 As shown, electric sliders 17 are driven and installed on the linear guide rail 18, and two electric lifting rods 11 are fixedly installed on the top of the two electric sliders 17 respectively. Specifically, by setting the electric sliders 17 and the linear guide rail 18, after the carton is straightened and clamped and limited by the correction beam 14, the electric sliders 17 on both sides will drive the electric lifting rods 11 to move the correction beam 14 at the top along the linear guide rail 18, so that the carton is conveyed to the bottom of the sealing mechanism body 3 under the limited condition. When the carton is sent to the first electric lifting platform 5, the correction mechanism will release the carton and reset it. The correction beams 9 on both sides will take over the correction beam 14 to limit the carton and prevent the carton from shifting position again during the conveying process after being corrected.

[0036] like Figure 5 As shown, height measuring frames 19 are fixedly installed on the top of the two horizontal sliding rods 13 located at the top. The two height measuring frames 19 are symmetrically distributed and located on the top of the two correction beams 14 respectively. Specifically, by setting the height measuring frames 19, before the correction mechanism corrects the position of the carton, the electric lifting rod 11 will drive the two correction beams 14 to move up and down, thereby causing the height measuring frames 19 on both sides to contact the top of the carton and measure the height of the carton, thus facilitating the height adjustment of the sealing mechanism body 3.

[0037] like Figure 3As shown, a correction platform 21 is fixedly installed inside the conveyor 1. In this embodiment, the sealing platform 4 and the upper surface of the correction platform 21 are at the same height. A second assembly hole is provided inside the correction platform 21, and a second electric lifting platform 22 is fixedly installed inside the second assembly hole. A correction turntable 23 is rotatably installed on the top of the second electric lifting platform 22. Specifically, by setting the second electric lifting platform 22, after the carton is conveyed by the conveyor 1 to the top of the correction platform 21, the second electric lifting platform 22 inside the second assembly hole will drive the correction turntable 23 to lift upward and lift the carton a short distance. Afterward, when the correction mechanism corrects the carton, the carton will rotate. The correction turntable 23 separates the bottom of the carton from the second electric lifting platform 22 and the correction platform 21, so that the carton can rotate smoothly without causing wear on the bottom. After the correction is completed, the second electric lifting platform 22 drives the carton to reset.

[0038] like Figure 1 As shown, a measuring gantry 24 is fixedly installed at the end of the conveyor 1 away from the electric lifting frame 2, such as... Figure 8 As shown, a first ultrasonic measuring instrument 25 is fixedly installed on the top of the measuring gantry 24, and inclined frames 26 are fixedly installed on both sides of the top of the measuring gantry 24. A second ultrasonic measuring instrument 27 is fixedly installed on one side of each inclined frame 26. Both the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27 face the conveyor 1. Specifically, by setting the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27, when the carton is sent to one end of the conveyor 1, the carton will pass through the measuring gantry 24 and be scanned by the first ultrasonic measuring instrument 25 directly above and the second ultrasonic measuring instruments 27 on both sides diagonally above, thereby detecting the shape and structure of the carton and obtaining the approximate data of the current length, width, height and orientation of the carton, thus providing a reference for the subsequent position adjustment of the sealing mechanism body 3 and the operation of the correction mechanism.

[0039] like Figure 4 As shown, a feeding conveyor belt 28 is fixedly installed inside each of the correction beams 9. In this embodiment, the feeding conveyor belt 28 has the same structure as the correction conveyor belt 16, and the size difference is subject to the actual situation. Specifically, by setting the feeding conveyor belt 28, when the carton is transported to the bottom of the sealing mechanism body 3, the correction beams 9 on both sides can clamp the feeding conveyor belt 28 on both sides of the carton, thereby driving the carton to move back and forth, changing the front and rear position of the carton, so as to cooperate with the sealing operation of the sealing mechanism body 3, and at the same time facilitate the feeding of the carton.

[0040] In summary: When using this adaptive correction carton sealing machine, the carton to be sealed is placed on one end of the conveyor 1, which transports the carton. When the carton is transported between the two correction mechanisms, its orientation is corrected. The carton then continues to be conveyed to the bottom of the sealing mechanism body 3, at which point it is positioned on top of the sealing table 4. The first electric push rods 8 on both sides drive the correction beam 9 to slide on the sealing table 4 until they contact the carton, thus performing secondary correction and limiting on the carton. Then, the electric lifting frame 2 drives the sealing mechanism body 3 to descend and seal the carton. The correction beam 9 then releases the carton, and the first electric lifting platform 5 drives the electric turntable 6 to rise in the first mounting hole until it contacts the bottom of the carton and lifts it up. At this point, the electric turntable 6 rotates the carton. The carton is rotated and repositioned. Then, the sealing mechanism body 3 descends again to perform a second sealing of the carton, completing the sealing process. By setting up a correction mechanism, when the carton is transported between two correction mechanisms, the electric lifting rod 11 drives the two correction beams 14 to rise and fall to match the current height of the carton. Then, the second electric push rods 15 on both sides drive the two correction beams 14 to move towards the carton until they contact it. This causes the carton to automatically return to its correct position under the push of the correction beams 14, completing automatic correction and preventing misalignment between the carton and the sealing mechanism body 3, which would affect the sealing accuracy. By setting up correction conveyor belts 16, when the correction beams 14 move towards the carton, the correction conveyor belts 16 on both sides rotate slowly in the opposite direction. When the carton is positioned relative to the sealing mechanism body 3... When there is a certain positional deviation, the alignment conveyor belt 16 will first contact the side of the carton, causing the hook strip 20 on the side of the alignment conveyor belt 16 to engage with the side of the carton, thereby causing the carton to rotate. When the carton returns to its upright position, the side wall of the carton will be parallel to the alignment conveyor belt 16. At this time, the alignment conveyor belt 16 stops rotating, and the alignment beams 14 on both sides drive the stationary alignment conveyor belt 16 to clamp and limit the carton, completing the alignment of the carton. By driving the carton to rotate in advance through the reverse rotation of the alignment conveyor belt 16, the alignment beams 14 on both sides are prevented from directly and rigidly contacting the side of the carton, thus preventing damage to the side of the carton. By setting electric sliders 17 and linear guides 18, after the carton returns to its upright position and is clamped and limited by the alignment beams 14, the electric sliders 17 on both sides will... The electric lifting rod 11 drives the top correction beam 14 to move along the linear guide rail 18, thereby allowing the carton to be conveyed to the bottom of the sealing mechanism body 3 while being limited. When the carton is delivered to the first electric lifting platform 5, the correction mechanism releases and resets the carton. The correction beams 9 on both sides take over from the correction beam 14 to limit the carton, preventing the carton from shifting position again during the conveying process after correction. By setting up the height measuring frame 19, before the correction mechanism corrects the position of the carton, the electric lifting rod 11 drives the two correction beams 14 to move up and down, thereby causing the height measuring frames 19 on both sides to contact the top of the carton and measure the height of the carton, thus facilitating the height adjustment of the sealing mechanism body 3. A second electric lifting platform 22 is also provided.After the carton is conveyed by conveyor 1 to the top of the alignment table 21, the second electric lifting platform 22 inside the second assembly hole drives the alignment turntable 23 to lift the carton upwards and raise it a short distance. Then, when the alignment mechanism corrects the carton, it rotates. The alignment turntable 23 separates the bottom of the carton from the second electric lifting platform 22 and the alignment table 21, allowing the carton to rotate smoothly without causing bottom wear. After correction, the second electric lifting platform 22 drives the carton to reset. By setting the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27, when the carton is sent to one end of conveyor 1, it passes through the measuring gantry. The frame 24 is then scanned by the first ultrasonic measuring instrument 25 directly above and the second ultrasonic measuring instruments 27 diagonally above on both sides, thereby detecting the shape and structure of the carton and obtaining approximate data on the current length, width, height, and orientation of the carton. This provides a reference for the subsequent position adjustment of the sealing mechanism body 3 and the operation of the correction mechanism. By setting up a feeding conveyor belt 28, when the carton is conveyed to the bottom of the sealing mechanism body 3, the correction beams on both sides can clamp the feeding conveyor belt 28 on both sides of the carton, thereby driving the carton to move back and forth, changing the front and back orientation of the carton to cooperate with the sealing operation of the sealing mechanism body 3, and at the same time facilitating the feeding of the carton.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
