Description

Technical Field

[0001] The present invention relates to a carton sealing machine mechanism, and more particularly to a side-sealing carton sealing machine. Background Art

[0002] A carton sealer is a device that seals the carton with tape to complete packaging. For ordinary carton packaging and sealing, the carton enters the carton sealer from one end, and the upper and lower surfaces are sealed with tape by the movement set up at the top and bottom. Now, for the transportation of fresh fruits and vegetables, foam boxes are used. The foam boxes and their lids are covered from top to bottom, so the corresponding carton sealer uses a side-set movement to seal the side tape. Figure 1 As shown, the existing side-sealing carton sealing machine has independent left and right movements, which require staff to debug separately. After debugging, it is necessary to check whether the two movements are at the same height. If they are not at the same height, they have to debug repeatedly, which is cumbersome. If they are not at the same height, it may affect the packaging aesthetics and even the sealing quality. On the other hand, the current side-sealing carton sealing machine adopts the method of setting conveyor belts in the upper and lower middle parts to clamp and drive the foam box to move forward. The conveyor belt has a certain width. For foam boxes that are too small, the movements on both sides cannot be closed and limited to convey and seal. For foam boxes that are too large, the upper and lower sides of the two outer sides are not well supported, which makes the structure unstable during transportation, affecting the sealing quality. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a side-sealing carton sealing machine, in which the height of the two side movements can be adjusted synchronously to improve the debugging efficiency, and a conveyor belt with adjustable width position is provided to better support and convey foam boxes of different sizes.

[0009] As an improvement, a second locking mechanism is also provided on the upper frame, and the second locking mechanism includes a second cylinder and a second resistance member, the second cylinder is provided on the upper frame, and the second resistance member is provided on the second cylinder; the second resistance member has an elastic surface, and when the second resistance member is driven by the second cylinder to press against the lower frame, the elastic surface and the lower frame outer shell resist each other to perform structural mechanical locking.

[0010] As an improvement, it also includes a sensor and a limit switch arranged at the feed end. The sensor is used to sense the arrival of the material at the feed end and feedback a signal, so that the first drive mechanism drives the upper bracket and the lower bracket on both sides to approach each other, the movement clamps the material, and the upper conveyor belt and the lower conveyor belt reach the upper and lower sides of the material respectively; the limit switch is set to move synchronously with the upper bracket and the lower bracket. When the upper bracket and the lower bracket are in place, the side limit switch contacts the material and feedbacks a signal, so that the second drive mechanism controls the upper bracket to descend until the upper conveyor belt contacts the material.

[0020] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 2 , 3, 4, 5, and 6 are specific embodiments of the side-sealing carton sealing machine of the present invention. This embodiment includes a frame 1, two groups of machine cores 4, two groups of upper conveyor belts 2, and two groups of lower conveyor belts 3. The two groups of upper conveyor belts 2 and the two groups of lower conveyor belts 3 are arranged on the frame 1 in correspondence with each other up and down. Machine cores 4 are arranged below the two groups of upper conveyor belts 2 for synchronous movement. The upper conveyor belts 2, lower conveyor belts 3, and machine cores 4 on both sides are controlled by a first driving mechanism 5 to approach and separate from each other in the horizontal direction. The upper conveyor belts 2 and the machine cores 4 are controlled by a second driving mechanism 6 to lift up and down. The frame 1 includes an upper frame 11 and a lower frame 12. The upper frame 11 is arranged on the lower frame 12 so as to be able to slide up and down. The upper conveyor belts 2 and the machine cores 4 are arranged on an upper bracket 21, and the lower conveyor belts 3 are arranged on a lower bracket 31. The lower bracket 31 is provided with a vertical Axis 32, the upper bracket 21 is arranged on the vertical axis 32 and can slide up and down, the lower frame 12 has a first horizontal axis 13 for the lower bracket 31 to be arranged and slide, the upper frame 11 has a second horizontal axis 14 for the upper bracket 21 to be arranged and slide, sprockets 15 are arranged on both sides of the upper frame 11, and a chain 16 is wound around the sprocket 15. The upper and lower sections of the chain 16 are respectively connected to the upper brackets 21 on both sides, and the second driving mechanism 6 drives the upper bracket 21 to rise and fall on the vertical axis 32; when the first driving mechanism 5 drives the upper bracket 21 on one side to move, the chain 16 moves clockwise or counterclockwise to drive the upper brackets 21 on both sides to move synchronously on the second horizontal axis 14 or move away, and the lower bracket 31 performs synchronous horizontal movement on the first horizontal axis 13.

[0022] When the present invention is in use, roller groups 9 are arranged on the lower frame 12 before and after the two groups of lower conveyor belts 3, and the foam box is sent to the roller group 9 at the feeding end manually or by a pushing mechanism. The width and height position of the upper conveyor belt 2, the lower conveyor belt 3, and the core 4 can be debugged by the staff in advance to make the width position match the foam box. Figure 3 As shown, the first driving mechanism 5 can be preferably a cylinder, whose left end is connected to the upper frame 11, and the driving end is connected to the right upper bracket 21. The left upper bracket 21 is connected to the upper chain 16, and the right upper bracket 21 is connected to the lower chain 16. When the cylinder is retracted, the right upper bracket 21 moves toward the middle, and the synchronous chain 16 rotates clockwise as a whole, and the left upper bracket 21 is driven to move toward the middle, thereby realizing the synchronous movement of the upper brackets 21 on both sides; and when the cylinder is extended, the whole performs a reverse action to separate the upper brackets 21 on both sides. The upper bracket 21, the vertical shaft 32, and the lower bracket 31 perform synchronous actions with each other, thereby realizing the synchronous approach and separation of the movements 4, the upper conveyor belt 2, and the lower conveyor belt 3 on both sides. As shown Figure 2As shown, the second driving mechanism 6 can be preferably a cylinder, the lower end of which is connected to the lower frame 12, and the driving end is connected to the upper frame 11 above. When the cylinder is retracted and extended, it drives the upper frame 11 to descend and ascend, and the movement 4 and the upper conveyor belt 2 connected to the upper frame 11 perform synchronous actions on the vertical axis 32. After the box is sealed, the foam box is output from the discharge end. As an optimization, the first driving mechanism 5 and the second driving mechanism 6 can be automatically started and stopped through the control module, automatically adjusted to adapt to the material specifications when the material is fed, reset after the box is sealed, and wait for the arrival of the next material; and a locking mechanism can be set to lock the position to adapt to the continuous sealing operation of the same specification.

[0023] As an improved specific implementation, a second transverse axis 14 is provided at the front and rear of the upper frame 11 , respectively. A set of sprockets 15 and chains 16 are provided near the two second transverse axes 14 , respectively. The two sets of sprockets 15 are connected by a connecting rod 17 .

[0024] like Figure 2 , 3 As shown, the upper conveyor belt 2 has a certain length, and at least two second transverse shafts 14 are set in front and behind for the upper bracket 21 to slide stably. At the same time, the front and rear two sets of sprockets 15 and chains 16 are set, which can better drive the upper brackets 21 on both sides to move. After the two sets of sprockets 15 are connected by a connecting rod 17, the structure is driven synchronously and moves synchronously, making the structure more stable and reducing the wear of parts. Correspondingly, the lower bracket 31 below can also be provided with at least two first transverse shafts 13 in front and behind to ensure that the structure is more stable and reduce the wear of parts.

[0025] As an improved specific implementation method, a first locking mechanism 51 is also provided on the upper frame 11, and the first locking mechanism 51 includes a first cylinder 52 and a first resistance member 53. The first cylinder 52 is provided on the upper frame 11, and the first resistance member 53 is provided on the first cylinder 52; a circle of toothed rings 171 is provided on the surface of the connecting rod 17, and the first resistance member 53 has tooth grooves 531 that match and mesh with the toothed rings 171. When the first resistance member 53 is driven by the first cylinder 52 to press against the connecting rod 17, the toothed ring 171 and the tooth grooves 531 are engaged to perform structural mechanical locking.

[0026] like Figure 3 , 5As shown in , 6, in order to achieve the locking of the structure to match the continuous sealing of products of different specifications and to make the sealing position more stable, the above structure is set; when the conveyor belt and the movement need to stay at a width position, the first cylinder 52 drives the tooth groove 531 of the first resistance member 53 to contact the tooth ring 171 of the connecting rod 17. When the two are in contact, the connecting rod 17 can be firmly locked, so that the connecting rod 17 cannot rotate, thereby locking the sprockets 15 and the chain 16 on both sides in one position, and the overall force is stable, which can well lock the cylinder and ensure the locking effect.

[0027] As an improved specific implementation method, a second locking mechanism 61 is also provided on the upper frame 11, and the second locking mechanism 61 includes a second cylinder 62 and a second resistance member 63. The second cylinder 62 is provided on the upper frame 11, and the second resistance member 63 is provided on the second cylinder 62; the second resistance member 63 has an elastic surface, and when the second resistance member 63 is driven by the second cylinder 62 to press against the lower frame 12, the elastic surface and the outer shell of the lower frame 12 are in resistance to perform structural mechanical locking.

[0028] like Figure 2 , 3 As shown in 4, the upper frame 11 is driven by the cylinders on both sides to move, so the second locking mechanism 61 can be set on both sides to achieve stable locking and limiting. Specifically, the second cylinder 62 is set on the upper frame 11. When the upper frame 11 needs to stay at a height position, the second cylinder 62 drives the second resistance member 63 to contact the lower frame 12. The second resistance member 63 firmly holds the upper frame 11 on the lower frame 12, realizing the function of mechanical locking. It has high stability and can meet the function of staying at different positions. The elastic surface of the second resistance member 63 can be a material such as rubber that has good elasticity and can provide good friction; the elastic surface ensures that the locking effect will not slip, and the wear between the structures is small, which is convenient for long-term use.

[0029] As an improved specific implementation method, it also includes a sensor 7 and a limit switch 8 arranged at the feed end. The sensor 7 is used to sense the arrival of the material at the feed end and feedback a signal, so that the first drive mechanism 5 drives the upper bracket 21 and the lower bracket 31 on both sides to approach each other, the movement 4 clamps the material, and the upper conveyor belt 2 and the lower conveyor belt 3 reach the upper and lower parts of the material respectively; the limit switch 8 is set to move synchronously with the upper bracket 21 and the lower bracket 31. When the upper bracket 21 and the lower bracket 31 are in place, the side limit switch 8 contacts the material and feedbacks a signal, so that the second drive mechanism 6 controls the upper bracket 21 to descend until the upper conveyor belt 2 contacts the material.

[0030] like Figure 2 , 3As shown, in order to further improve the automatic debugging function of the side-sealing carton sealing machine and meet the rapid sealing of foam boxes of different specifications, the above structure is set. After the foam box is sent to the feed end by manual or pushing mechanism and is sensed by the sensor 7, the sensor 7 is preferably a photoelectric sensor, and its feedback signal is given to the control module. The control module starts the first drive mechanism 5 to make the movement 4, the upper conveyor belt 2 and the lower conveyor belt 3 reach the width position matching the foam box. When they arrive, the first drive mechanism 5 can be stopped. When the position needs to be locked, the first locking mechanism 51 cooperates to lock the position; when they arrive, the limit switch 8 contacts the foam box, and the feedback signal is given to the control module. The control module starts the second drive mechanism 6 to make the upper conveyor belt 2 drop to contact the foam box, and the movement 4 also reaches the position of the tape sealing. When they arrive, the second drive mechanism 6 can be stopped. When the position needs to be locked, the second locking mechanism 61 cooperates to lock the position. The foam box driven by the conveyor belt travels to seal the box to complete the side sealing on both sides and is output from the discharge end. The foam box that has completed the sealing on both sides can be sent to the next side-sealing carton sealing machine to complete the side sealing on the other two sides. Relying on the setting of the above structure, automatic position debugging can be completed. When processing foam boxes of the same specification, the position can be locked. When processing foam boxes of different specifications, the mechanism can be reset and the above steps can be repeated to debug and seal the boxes.

[0031] As an improved specific implementation method, it also includes a roller group 9 arranged at the feed end, the roller group 9 can be rotatably arranged on the frame 1 and extends to the lower conveyor belt 3, the side of the upper conveyor belt 2 close to the feed end is longer than the lower conveyor belt 3, and the upper conveyor belt 2 extends to the top of the roller group 9; the sensor 7 and the limit switch 8 are located on the side between the upper conveyor belt 2 and the roller group 9; when the upper conveyor belt 2 drops to contact the material, the upper conveyor belt 2 cooperates with the roller group 9 to transport the material to the lower conveyor belt 3.

[0032] like Figure 2 , 3 As shown, the above structure ensures that the overall width and height are adjusted during debugging. The foam box is stably placed on the roller set 9 at the feed end. It has not yet reached the lower conveyor belt 3 and can be well placed on the roller set 9. After being detected, until the upper conveyor belt 2 drops to contact the foam box, the foam box can be driven by the upper conveyor belt 2 to be transported forward until it passes the roller set 9 at the feed end. It can be clamped up and down by the upper conveyor belt 2 and the lower conveyor belt 3 for transportation, and then sealed when passing through the movement 4; the debugging quality is guaranteed, and it can be well driven for transportation after the debugging is completed.

[0033] As an improved specific implementation, the movement 4 also includes a guardrail 41, which is arranged close to the lower conveyor belt 3 and is used to clamp materials at the side. The guardrail 41 extends to the roller group 9, and the limit switch 8 is arranged on the guardrail 41.

[0034] like Figure 2 ,3 As shown, the main body of the movement 4 is located in the middle of the carton sealing machine, and the guardrail 41 is arranged downward, which can be used to cooperate well with the limiting foam box, and it is extended to the roller group 9, which can cooperate with the side limiting and cooperate with the conveyor belt 2 for smooth transportation, and can serve as a good position for the setting of the limit switch 8.

[0035] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
