Description

Technical Field

[0001] The utility model relates to the technical field of carton bundling, in particular to a limiting device for bundling packaging cartons. Background Art

[0002] A strapping machine, also known as a baler, strapping machine or baler, is a machine that uses strapping tape to tie products or packages. Its function is to reinforce the packaged items so that the items will not be scattered during transportation or storage due to loose strapping. In addition, the strapping machine can also combine the two ends through hot-melt bonding with a heating iron, making the strapping neat and beautiful. Fully automatic strapping machines are used in the final stage of packaging to strap cartons with strapping tape to prevent them from scattering during transportation. There are many advantages to using an automatic strapping machine, such as the beautiful and firm strapping produced by the cartons, the fast working speed, which greatly improves the workers' packaging efficiency. At the same time, it can also reduce waste and save costs.

[0003] like Figure 1 As shown, an empty slot is opened in the center of the working table of the existing carton strapping and packaging machine. The operator places the stack of cartons to be strapped on the table. When placing the cartons, the stack must cross the empty slot. Then the power device on the machine body drives the strapping arm to rotate one circle. The strapping arm passes through the empty slot area when rotating, and uses the strapping mechanism to strap the stack of cartons on the table. During this period, due to the limitation of the empty slot on the table of the strapping machine itself, some existing limit clamps cannot be used on this strapping machine. This results in the operator manually limiting the stack of cartons during the actual strapping period, which means that the operator still needs to keep the limit on the stack of cartons during the strapping period, which not only increases the labor intensity, but also affects the strapping efficiency and effect. In view of this, we propose a limit device for strapping carton packaging. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a limiting device for packaging carton bundling, which solves the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A limiting device for packaging cartons and bundling, comprising a body, on which are arranged two symmetrical side limiting bases, the side limiting bases comprising a front base, a rear base and a yielding connecting frame connecting the front base and the rear base, a driving device being arranged on the two side limiting bases, a guide base being fixedly connected to the body, and front and rear limiting devices being arranged on the body.

[0007] Preferably, the driving device includes a mounting base which is mounted on the machine body. An electric push rod is mounted on the mounting base. The output shaft of the electric push rod is connected to a moving base. Two sliding shafts are fixedly connected to the moving base. The ends of the two sliding shafts are both slidably connected to inclined frames.

[0008] Preferably, the two inclined frames are arranged in a staggered state, and the tops of the two inclined frames are respectively fixed to the bottom of the front base and the bottom of the rear base.

[0009] Preferably, the front and rear limiting device includes a compression spring. One end of the compression spring is connected to the inner wall of the front base, and the other end of the compression spring is fixedly connected to a clamping plate. A magnetic limiting slider is fixedly connected to the clamping plate.

[0010] Preferably, a magnetic plate and a guiding inclined surface are respectively arranged on the guiding base. The magnetic plate is magnetically connected to the magnetic limiting slider.

[0011] Preferably, a limiting groove for the linear sliding of the inclined frame is formed on the machine body, and a groove for the sliding of the magnetic limiting slider is formed on the top of the front base.

[0012] By means of the above technical solution, the utility model provides a limiting device for bundling packaging cartons. It has at least the following beneficial effects:

[0013] (1) For the limiting device for bundling packaging cartons, by setting the driving device, the force of the up-and-down movement is converted into the left-and-right lateral movement force, so as to drive the two side limiting bases to move closer. The two groups of front bases and rear bases distributed left and right are adjusted for the left-and-right position limiting of the carton stack in the working area of the machine body through approaching. The two sets of split limiting methods are adopted to avoid the problem of interference between the traditional integral limiting method and the bundling arm while achieving the automatic limiting of the carton stack. Combining the cooperation of the front and rear limiting device and the guiding base, the front-and-rear position adjustment of the carton stack in the left-and-right limiting is realized, and then the effect of limiting the carton stack in the left-and-right and front-and-rear four sides in sequence is achieved, improving the automation in the carton bundling system and achieving the effect of automatically limiting and adjusting the carton stack.

[0014] (2) For the limiting device for bundling packaging cartons, by setting the length of the magnetic plate to be less than the lateral movement distance of the front base, when the carton stack is almost pushed to the left-and-right center line of the workbench, the magnetic limiting slider will be disengaged from the magnetic force due to the dislocation with the magnetic plate. At this time, the magnetic limiting slider moves longitudinally under the elastic force of the compression spring on the clamping plate, and the clamping plates at the front bases and rear bases on both sides move closer. During the approaching process, the force of the spring reset is used to drive the front and rear sides of the carton stack within this range to be aligned and limited.

[0015] (3) The limiting device for packaging cartons and bundling is provided with a guiding slope. When the clamp pushes the carton stack to adjust the front and rear positions, the carton stack is limited and bundled on the four sides. Then, the side limiting base needs to be controlled to move and reset. The setting of the guiding slope can synchronously perform the longitudinal guiding and resetting movement during the lateral movement and resetting of the magnetic limiting slider. When the magnetic limiting slider is limited to the magnetic plate, the magnetic force is used again to position the magnetic limiting slider, and the structure at the auxiliary side limiting base is reset to the initial state as a whole for repeated use.

[0016] (4) A limiting device for packaging cartons and bundling, by setting a driving device, drives two sliding shafts on a movable base through an electric push rod to drive two inclined frames to move, and when the sliding shaft moves upward, it drives the two inclined frames that are limited to only horizontal linear movement to move closer, and converts the up and down movement force into left and right lateral movement force, thereby driving the two side limiting bases to position the two sides of the carton stack during the approach movement, thereby achieving the effect of automatic limiting and adjustment of the carton stack.

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figures 2 - 6 , a technical solution provided by the utility model:

[0027] A limiting device for packaging carton strapping comprises a machine body 1, on the worktable surface of the machine body 1 are slidably connected two symmetrical side limiting bases 2, the side limiting bases 2 comprise a front base 21, a rear base 22 and a giving way connecting frame 23 connecting the front base 21 and the rear base 22, a giving way cavity is provided in the central area of ​​the giving way connecting frame 23 for giving way to the strapping arm rotating on the machine body 1, and at the same time, the setting of the giving way connecting frame 23 enables the front base 21 and the rear base 22 to move synchronously, and the front base 21 and the rear base 22 can be combined with each other to form a plurality of side limiting bases 21 and 22, respectively. Figure 2 The two groups of front bases 21 and rear bases 22 distributed in left and right pairs can move towards each other, and during the approach, the cardboard stacks in the working area of ​​the machine body 1 can be limited and adjusted. The two groups of separately arranged limiting methods are adopted to achieve automatic limiting of the cardboard stacks while avoiding the problem of interference between the traditional integrated limiting method and the strapping arm, thereby improving the automation in the cardboard strapping system. A driving device 3 is arranged at the bottom of the two side limiting bases 2. The driving device 3 converts the up and down movement force into left and right lateral movement force through the internal structure, so as to drive the two side limiting bases 2 to achieve the effect of automatic limiting and adjusting the cardboard stacks during the approach movement. Four guide bases 4 that are symmetrical in front and back and then in left and right are fixedly connected to the surface of the workbench of the machine body 1. The four guide bases 4 correspond to the two front bases 21 and the rear base 22 distributed in left and right pairs respectively, and a front and rear limiting device 5 is arranged on the machine body 1.

[0028] In this embodiment, the driving device 3 includes a mounting base 31. The surface of the mounting base 31 is detachably mounted on the machine body 1 by bolts. An electric push rod 32 is detachably mounted on the mounting base 31 by bolts. The output shaft of the electric push rod 32 is detachably connected to a moving base 33 by a coupling. Two sliding shafts 34 are fixedly connected to the moving base 33. The ends of the two sliding shafts 34 are both slidably connected to an inclined frame 35. A limiting groove for the linear sliding of the inclined frame 35 is formed on the machine body 1. The two inclined frames 35 are arranged in a staggered state. When the moving base 33 moves upward and drives the two inclined frames 35 to approach each other, the two inclined frames 35 perform a staggered approaching movement, thus avoiding interference between the two approaching inclined frames 35. The tops of the two inclined frames 35 are respectively fixed to the bottoms of the front base 21 and the rear base 22. The driving device 3 drives the two sliding shafts 34 on the moving base 33 to drive the two inclined frames 35 to move through the electric push rod 32. When the sliding shafts 34 move upward, they drive the two inclined frames 35, which are limited to only perform horizontal linear movement, to move closer. The force of the up-and-down movement is converted into a left-right horizontal movement force, so as to drive the two side limiting bases 2 to position the two sides of the carton stack during the approaching movement, thereby achieving the effect of automatically limiting and adjusting the carton stack.

[0029] Furthermore, the front and rear limiting device 5 includes a compression spring 51. As Figure 2 shown, the compression spring 51 is in a compressed state. One end of it is connected to the inner wall of the front base 21, and the other end of the compression spring 51 is fixedly connected to a clamping plate 52. A magnetic force limiting slider 53 is fixedly connected to the clamping plate 52. The clamping plate 52 provides a continuous limiting force to the compression spring 51 through the magnetic force limitation on the magnetic force limiting slider 53. When the magnetic force is disengaged, the compression spring 51 can use the elastic reset to drive the clamping plate 52 to move back and forth, so as to use the power of the back-and-forth movement to realize the adjustment work on the front and rear sides of the carton stack that is limited on the left and right sides, and then realize the effect of limiting the left, right, front, and rear four sides of the carton stack in sequence, achieving the purpose of automatically limiting the four sides of the carton stack.

[0030] Even further, magnetic plates 41 and guiding inclined surfaces 42 are respectively arranged on the guiding base 4. As Figure 3As described above, the length of the magnetic plate 41 is smaller than the lateral movement distance of the front base 21. When the carton stack is about to be pushed to the left or right center line of the workbench, the magnetic limit slider 53 will be disengaged from the magnetic force due to the misalignment with the magnetic plate 41. At this time, the magnetic limit slider 53 is longitudinally moved by the elastic force of the compression spring 51 on the clamping plate 52. The clamping plates 52 at the front base 21 and the rear base 22 on the left and right sides all move closer. During the approach, the spring reset force is used to drive the front and rear sides of the carton stack within the range to align and limit. The magnetic plate 41 is magnetically connected to the magnetic limit slider 53, and the guide slope 42 is operated. The purpose is that after the clamp 52 pushes the carton stack to adjust the front and rear positions, and the carton stack is limited and bundled on four sides, it is necessary to control the side limit base 2 to move and reset. The setting of the guide slope 42 can synchronously perform the longitudinal guide reset movement while the magnetic limit slider 53 is moving horizontally and resetting. After the magnetic limit slider 53 is limited to approach the magnetic plate 41, the magnetic force is used again to position the magnetic limit slider 53, and the overall structure of the side limit base 2 is reset to the initial state for repeated use. A groove for the magnetic limit slider 53 to slide is provided on the top of the front base 21.

[0031] When the limiting device for packaging cartons and bundling of the utility model is in use, the operator places the stack of cartons to be bundled on the workbench of the machine body 1. When placing, it is necessary to pay attention to placing the stack of cartons in the area between the two side limiting bases 2 located on the machine body 1. After placing, the operator moves away from the workbench and starts the electric push rod 32. The output shaft of the electric push rod 32 drives the sliding shaft 34 to drive the two inclined frames 35 to approach each other through the moving base 33. The two inclined frames 35 drive the left and right rear bases 22 to approach synchronously through the left and right front bases 21 and the yielding connecting frame 23. During the approach, the left and right front bases 21 and the rear base 22 achieve the effect of aligning and clamping the left and right sides of the carton stack, and then realize the purpose of automatically limiting the two sides of the carton stack. When the carton stack is limited to the left and right center lines of the workbench, with the lateral movement of the front base 21, the magnetic limiting slider 53 limited by the top groove of the front base 21 moves synchronously. During the movement, the magnetic limiting slider 53 is magnetically adsorbed by the magnetic plate 41, such as Figure 3As described above, the length of the magnetic plate 41 is less than the distance of the lateral movement of the front base 21. When the carton stack is about to be pushed to the left and right center line of the workbench, the magnetic limit slider 53 will be disengaged from the magnetic force due to the misalignment with the magnetic plate 41. At this time, the magnetic limit slider 53 moves longitudinally under the elastic force of the compression spring 51 on the clamping plate 52. The clamping plates 52 at the front bases 21 and the rear bases 22 on both sides move closer. During the approaching process, the elastic force of the spring reset is used to drive the front and rear sides of the carton stack within this range to be aligned and limited, so as to achieve the effect of aligning and limiting the front, rear, left and right sides of the carton stack in sequence. By adopting the two-group split-type limiting method, while achieving automatic limiting of the carton stack, the problem of interference between the traditional integral limiting method and the bundling arm is avoided, and the automation in the carton bundling system is improved.
