Abstract
Description
Technical Field
[0001] This utility model relates to the field of box sealing technology, and in particular to a continuous automatic box sealing device. Background Technology
[0002] Automatic carton sealing devices are equipment used in automated packaging production lines, widely applied in various industries such as food, daily chemicals, electronics, and home appliances. They significantly improve packaging efficiency and reduce manual labor. Their main function is to automatically seal cartons containing goods, ensuring the safety and integrity of the packaging. Compared to traditional manual sealing, automatic carton sealing devices significantly improve production efficiency, reduce labor costs, and guarantee consistent sealing quality. A typical sealing system includes a carton flap folding mechanism and a carton sealing mechanism, which closes the flaps at the top of the carton and seals the surface with tape. Automatic carton sealing devices play a crucial role in modern production lines, improving production efficiency and reducing labor costs, making them an important component of large-scale production and logistics management.
[0003] However, when the sealing device operates continuously, the ear on the side furthest from the folding mechanism needs to be folded using a separate mechanism. Traditional automatic sealing devices generally use a folding rod to push the ear furthest from the folding mechanism to close and flatten it. For example, invention patent CN110282172B discloses an automatic sealing machine, including a support platform and a conveying assembly. The conveying assembly is equipped with a closing linkage that pushes a longitudinal cover on the box body to close inward. This technical solution can fold the ear on the upper side of the box body in its normal state by swinging the closing linkage. However, if the ear is tilted downward at too large an angle, the swinging of the closing linkage cannot contact the ear, meaning it cannot control the ear to close, resulting in the box body not being properly sealed and increasing the packaging defect rate. Therefore, the field of sealing technology needs to propose a continuous automatic sealing device that can reliably fold and seal the ear on the upper part of the box body. Utility Model Content
[0004] In view of the above-mentioned prior art, the present invention provides a continuous automatic box sealing device, the main technical problem to be solved is how to more reliably fold and seal the upper box ears of the box.
[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:
[0006] A continuous automatic box sealing device includes a support, a conveying track, a box folding lug mechanism, a box sealing mechanism, a box lug folding rod, and a positioning and CNC system. A first folding auxiliary mechanism is provided on one side of the conveying track. The first folding auxiliary mechanism includes a housing, an auxiliary telescopic rod, a rotating rod, a sleeve, and a correcting rod. The auxiliary telescopic rod is disposed inside the housing and is rotatably connected to the rotating rod. The rotating rod is fixedly connected to the correcting rod. The sleeve is fixedly connected to the housing. A helical slider is provided on the outer side of the rotating rod, and a helical groove is provided on the inner side of the sleeve to cooperate with the helical slider. The telescopic movement of the auxiliary telescopic rod drives the rotating rod and the correcting rod to rotate through the helical slider and the helical groove.
[0007] Preferably, a second folding auxiliary mechanism is symmetrically arranged on the opposite side of the first folding auxiliary mechanism on the conveying track, and the second folding auxiliary mechanism is configured to have the same structure and size as the first folding auxiliary mechanism.
[0008] Preferably, a first adjusting telescopic rod is provided at the connection between the first folding auxiliary mechanism and the conveying track, and a second adjusting telescopic rod is provided at the connection between the second folding auxiliary mechanism and the conveying track.
[0009] Preferably, the bracket has symmetrically arranged adjustment support rods in the middle, and one side of the adjustment support rod is provided with an adjustment groove. The adjustment support rod is slidably connected to the adjustment connecting rod through the adjustment groove. The box body folding mechanism, the box body sealing mechanism and the box ear folding rod are all fixedly connected to the adjustment connecting rod.
[0010] Preferably, the bottom of the bracket is provided with casters, which are connected to the four corners of the bracket respectively.
[0011] Preferably, the conveying track includes a horizontal conveying roller and a vertical conveyor belt, with the vertical conveyor belt symmetrically arranged above the horizontal conveying roller.
[0012] Preferably, the surface of the vertical conveyor belt is provided with anti-slip protrusions.
[0013] The beneficial effects of this utility model are as follows: By setting a first folding auxiliary mechanism, this application can assist the box body folding lug mechanism and the lug folding rod in sealing the box. When the rear lug of the carton body unfolds at too large an angle, the auxiliary telescopic rod extends, and the rotating rod is pushed by the auxiliary telescopic rod into the sleeve, moving towards the direction closer to the carton body. At the same time, it rotates under the action of the spiral slider and the spiral groove. The rotation of the rotating rod drives the correction rod to rotate, pushing the rear lug to move upward. After the rear lug is corrected, the rotating rod and the correction rod retract under the action of the contraction movement of the auxiliary telescopic rod, and rotate back to their original state through the action of the spiral slider and the spiral groove. Through the movement of the correction rod, the outward unfolding angle of the rear lug is reduced, thereby allowing the swinging movement of the lug folding rod to contact the rear lug and push the rear lug to close and flatten, ensuring that the carton body can be sealed normally.
[0014] In summary, by setting up a first folding auxiliary mechanism, this application can more reliably fold and seal the box ears at the top of the box, thereby reducing the packaging defect rate. Attached Figure Description

[0027] Example 1
[0028] See attached document Figure 1-4This application provides a continuous automatic box sealing device, including a support 1, a conveying track 2, a box folding lug mechanism 3, a box sealing mechanism 4, a box lug folding rod 5, and a positioning and CNC system 6. A first folding auxiliary mechanism 7 is provided on one side of the conveying track 2. The first folding auxiliary mechanism 7 includes a housing 701, an auxiliary telescopic rod 702, a rotating rod 703, a sleeve 704, and a correcting rod 705. The auxiliary telescopic rod 702 is disposed inside the housing 701 and is rotatably connected to the rotating rod 703. The rotating rod 703 is fixedly connected to the correcting rod 705. The sleeve 704 is fixedly connected to the housing 701. A spiral slider 706 is provided on the outer side of the rotating rod 703, and a spiral groove 707 that cooperates with the spiral slider 706 is provided on the inner side of the sleeve 704. The telescopic movement of the auxiliary telescopic rod 702 drives the rotating rod 703 and the correcting rod 705 to rotate through the spiral slider 706 and the spiral groove 707. This device, by setting a first folding auxiliary mechanism 7, can assist the box body folding mechanism 3 and the box ear folding rod 5 in sealing the box. When the rear box ear 801 of the carton body 8 unfolds at too large an angle, the auxiliary telescopic rod 702 extends, and the rotating rod 703 is pushed by the auxiliary telescopic rod 702 into the sleeve 704, moving towards the direction close to the carton body 8. At the same time, it is rotated by the action of the spiral slider 706 and the spiral groove 707. The rotation of the rotating rod 703 drives the straightening rod 705 to rotate and push the rear box ear 801 to move upward. After the rear box ear 801 is straightened, the rotating rod 703 and the straightening rod 705 retract under the action of the contraction movement of the auxiliary telescopic rod 702, and rotate back to their original state by the action of the spiral slider 706 and the spiral groove 707. The movement of the corrector rod 705 reduces the outward angle of the rear ear 801, allowing the swinging motion of the ear folding rod 5 to contact the rear ear 801 and push it to close and flatten, ensuring the carton body 8 can be sealed properly. The auxiliary telescopic rod 702 is signal-connected to the positioning and CNC system 6. When the rear ear approaches the first folding auxiliary mechanism 7, the positioning and CNC system 6 controls the auxiliary telescopic rod 702 at the first folding auxiliary mechanism 7 to extend. After the rear ear 801 is corrected, the auxiliary telescopic rod 702 retracts. (See attached diagram.) Figure 2 In this embodiment, the correction rod 705 at the first folding auxiliary mechanism 7 is configured to rotate clockwise when the auxiliary telescopic rod 702 is extended.
[0029] In summary, by incorporating the first folding auxiliary mechanism 7, this device can more reliably fold and seal the box ears at the top of the box, thereby reducing the packaging defect rate.
[0030] Specifically, a second folding auxiliary mechanism 9 is symmetrically arranged on the opposite side of the first folding auxiliary mechanism 7 on the conveying track 2. The second folding auxiliary mechanism 9 is configured to have the same structure and size as the first folding auxiliary mechanism 7. The second folding auxiliary mechanism 9 can perform movements similar to the first folding auxiliary mechanism 7, such that the corrective rod 705 at the second folding auxiliary mechanism 9 extends when the front ear 802 passes by, and rotates counterclockwise under the action of the spiral slider 706 and the spiral groove 707 at the second folding auxiliary mechanism 9, pushing the front ear 802 to rotate, thereby reducing the unfolding angle of the front ear 802. The front ear 802 can then be folded and flattened under the push of the box body folding mechanism 3. This prevents the unfolding angle of the front ear 802 from being too large, which would prevent it from being properly flattened and sealed.
[0031] Specifically, a first adjusting telescopic rod 10 is provided at the connection between the first folding auxiliary mechanism 7 and the conveying track 2, and a second adjusting telescopic rod 11 is provided at the connection between the second folding auxiliary mechanism 9 and the conveying track 2. The first adjusting telescopic rod 10 and the second adjusting telescopic rod 11 can adjust the height of the first folding auxiliary mechanism 7 and the second folding auxiliary mechanism 9, making it easier to adapt to different carton bodies 8.
[0032] Specifically, the support rod 101 is symmetrically arranged in the middle of the bracket 1. An adjustment groove 102 is provided on one side of each support rod 101. The support rod 101 is slidably connected to the connecting rod 103 via the adjustment groove 102. The box body folding mechanism 3, the box body sealing mechanism 4, and the box ear folding rod 5 are all fixedly connected to the connecting rod 103. The support rod 101, in conjunction with the adjustment groove 102 and the connecting rod 103, can adjust the height of the box body folding mechanism 3, the box body sealing mechanism 4, and the box ear folding rod 5, enabling the device to reliably use cardboard boxes 8 of different specifications.
[0033] Specifically, the bottom of the support frame 1 is provided with casters 104, which are connected to the four corners of the support frame 1. The casters 104 enable the device to be moved easily, facilitating transportation and transfer during production.
[0034] Example 2
[0035] See attached document Figure 1-2 The difference between this embodiment and Embodiment 1 is that the conveying track 2 includes a horizontal conveying roller 201 and a vertical conveyor belt 202, with the vertical conveyor belt 202 symmetrically arranged above the horizontal conveying roller 201. The vertical conveyor belt 202 can clamp the carton body 8, preventing the carton body 8 from deviating from the track during movement.
[0036] Specifically, the surface of the vertical conveyor belt 202 is provided with anti-slip protrusions 203. The anti-slip protrusions 203 can improve the conveying effect of the vertical conveyor belt 202 and reduce the relative sliding between the carton body 8 and the vertical conveyor belt 202.
[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
