Description

Technical Field

[0001] This utility model relates to the field of packaging technology for packaging bag production, specifically a device for packaging vacuum bags into boxes. Background Technology

[0002] Vacuum packaging bags are special bags used for packaging food, preserving ingredients, or other items. They create a vacuum environment by removing air from the packaging, thus extending the shelf life of the food and effectively preventing oxidation, spoilage, and bacterial growth. After production, the vacuum packaging bags are stacked to form a finished product stack. This stack is then folded and rolled up to form a packaging bag roll, which is subsequently packaged to obtain the finished product.

[0003] For example, the patent document with application number 202020449383.1 discloses an automatic packaging bag packing machine, and specifically discloses that by tilting the guide plate, the packaging bags on the conveyor belt are directly transported into the packaging box to realize the packing operation of vacuum packaging bags.

[0004] In the above technical solution, when the packaging bag roll is fed through the guide plate, the packaging bag roll needs to be parallel to the guide plate. If the packaging bag roll is tilted, one end of the packaging bag roll will first contact the guide plate, and when the other end of the packaging bag roll contacts the guide plate, the packaging bag roll is tilted. When it slides down under the action of gravity, the packaging bag is very likely to tilt, which may cause the packaging bag roll to slide off the guide plate. Or, due to the tilting problem, the arrangement direction of the packaging bag roll during packing is unstable, resulting in a messy arrangement and affecting the neatness of the packaging bag during packing. Utility Model Content

[0005] The technical problem solved by this utility model is to address the issue that, in the prior art, when the packaging bag roll slides down the guide plate into the box, the packaging bag roll may be tilted during feeding, resulting in an uneven arrangement of the packaging bag roll.

[0006] This utility model can be achieved through the following technical solution: a vacuum packaging bag packaging box device, including a conveyor belt, the conveyor belt being controlled by a conveyor roller, a leveling roller being provided on the conveyor belt, the leveling roller and the conveyor belt moving in parallel directions, and the height of the leveling roller being adjustable.

[0007] A further technical improvement of this utility model is that the leveling roller is rotatably mounted on the leveling slider, and the leveling slider is mounted on the output end of the leveling cylinder.

[0008] A further technical improvement of this utility model is that: the regulating cylinder is mounted on the limiting plate, the limiting plate is mounted on the rotating plate, and the regulating slider and the rotating plate are slidably connected.

[0009] A further technical improvement of this utility model is that the rotating plate and the frame are slidably connected, and the sliding trajectory of the rotating plate and the frame is circumferential, with the rotating plate mounted on an eccentric wheel.

[0010] A further technical improvement of this utility model is that the regular cylinders are symmetrically installed on the limiting plate.

[0011] A further technical improvement of this utility model is that the eccentric wheel is installed at the output end of the regular motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application solves the problem of uneven arrangement of packaging bag rolls caused by tilted feeding in the prior art. When the vacuum packaging bag roll is placed on the conveyor belt for conveying, the height of the alignment roller is controlled to bring it close to the conveyor belt, thereby limiting the vacuum packaging bag roll. At this time, one end of the vacuum packaging bag directly contacts the alignment roller. Under the rotation of the conveyor belt and the inertia of the vacuum packaging bag roll, the vacuum packaging bag roll gradually becomes parallel to the alignment roller, thus making the vacuum packaging bag roll move in parallel.

[0014] 2. This application utilizes a aligning motor to drive an eccentric wheel to rotate, thereby causing the rotating plate to slide circumferentially. That is, after the aligning roller adjusts the arrangement of the vacuum packaging bag roll, the rotation of the eccentric wheel causes the aligning roller to move away from the vacuum packaging bag under circumferential action, avoiding the direct longitudinal movement of the aligning roller from affecting the parallel position of the vacuum packaging bag roll, so that the vacuum packaging bag roll can maintain a parallel direction for moving and feeding.

[0015] 3. This application uses symmetrically arranged leveling cylinders on both sides of the limiting plate to control the lateral position of the leveling rollers. When the vacuum packaging bag roll first contacts the leveling roller, the leveling roller moves in the opposite direction to the conveyor belt, which speeds up the leveling of the vacuum packaging bag roll and ensures the leveling efficiency of the vacuum packaging bag roll. At the same time, the function of setting two sets of leveling rollers can level the position of two sets of vacuum packaging bag rolls at the same time, which improves the leveling efficiency of the vacuum packaging bag roll.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-4 As shown, the vacuum packaging bag packaging box making device includes a conveyor belt 2, wherein the conveyor belt 2 is driven by a conveyor roller 1. That is, the conveyor roller 1 is installed on the frame through a conveyor motor. The conveyor motor drives the conveyor roller 1 to rotate, thereby causing the vacuum packaging bag to move and be conveyed on the conveyor belt 2. At this time, the vacuum packaging bag is rolled up.

[0024] A straightening mechanism 3 is provided on the conveyor belt 2. The straightening mechanism 3 is used to adjust the vacuum packaging bag roll so that the vacuum packaging bag roll is parallel to the moving direction of the conveyor belt 2, which facilitates the transfer of the vacuum packaging bag roll from the conveyor belt 2 to the guide plate, and facilitates the guide plate to convey and unload the vacuum packaging bag roll.

[0025] The straightening mechanism 3 includes a straightening roller 35, the longitudinal height of which is adjustable. The straightening roller 35 is arranged parallel above the conveyor belt 2. In use, when the vacuum packaging bag roll is on the conveyor belt 2, the straightening roller 35 is controlled to move longitudinally, so that the straightening roller 35 is close to the conveyor belt 2. At this time, the non-flush end of the vacuum packaging bag roll first contacts the straightening roller 35. The straightening roller 35 is used to limit the non-flush end of the vacuum packaging bag roll. Under the conveying action of the conveyor belt 2, the non-flush end of the vacuum packaging bag roll gradually approaches the straightening roller 35 until the vacuum packaging bag roll is parallel to the conveyor belt 2.

[0026] In order to control the longitudinal movement of the straightening roller 35, a straightening motor 31 is fixed on the frame, and an eccentric wheel 38 is fixed at the output end of the straightening motor 31. A bearing seat 32 is fixed at the non-center position of the eccentric wheel 38, and a rotating shaft is rotatably mounted on the bearing seat 32. A rotating plate 37 is fixedly installed at the end of the rotating shaft away from the bearing seat 32, and the straightening roller 35 is rotatably mounted on the rotating plate 37 through a connecting assembly.

[0027] In this technical solution, the starting of the regulating motor 31 drives the eccentric wheel 38, which in turn rotates the shaft, causing the rotating plate 37 to move along a circumferential path under the action of the limit. The lateral and longitudinal positions of the rotating plate 37 can be adjusted. Therefore, in this application, the rotating plate 37 is slidably connected to the frame, and the sliding trajectory is circumferential.

[0028] The connecting component includes a limiting plate 33, which is fixedly connected to a rotating plate 37. A leveling cylinder 34 is fixed to the side of the limiting plate 33. A leveling slider 36 is installed at the end of the leveling cylinder 34. The leveling slider 36 is slidably connected to the rotating plate 37. A leveling roller 35 is rotatably mounted on the leveling slider 36.

[0029] In this application, the sizing cylinder 34 is activated to control the sizing slider 36 to slide, that is, to control the sizing slider 36 to slide on the rotating plate 37, thereby controlling the lateral position of the sizing roller 35 and realizing the sizing effect on the vacuum packaging bag roll. That is, if the vacuum packaging bag roll is to be sized quickly, when the vacuum packaging bag roll comes into contact with the sizing roller 35, the sizing cylinder 34 is activated to control the sizing roller 35 to move. At this time, the relative movement speed between the sizing roller 35 and the conveyor belt 2 can accelerate the sizing speed of the vacuum packaging bag roll.

[0030] An end plate is also slidably mounted on the frame, wherein the sliding trajectory of the end plate and the frame is circumferential. A limit rod 39 is fixed on the end plate, wherein an end slider is slidably mounted on the limit rod 39, and the end slider is rotatably connected to the straightening roller 35.

[0031] When the sizing roller 35 is moved and adjusted, in order to achieve the stability of the movement of the sizing roller 35, the end plate is used to limit the movement of the sizing roller 35, so as to ensure that the sizing roller 35 can move in parallel, thereby ensuring the stability of the movement of the vacuum packaging bag roll.

[0032] To further achieve the adjustment function of the vacuum packaging bag roll, symmetrically arranged straightening cylinders 34 are provided on both sides of the limiting plate 33. The straightening rollers 35 moving in opposite directions are used to straighten the vacuum packaging bag roll. At the same time, the straightening operation of two sets of vacuum can packaging bag rolls can be achieved by using two sets of straightening rollers 35, which improves the straightening efficiency of the vacuum packaging bag roll and thus improves the packaging efficiency of the vacuum packaging bag roll.

[0033] When using this utility model, the packaging bag roll is first placed on the conveyor belt 2. The vacuum packaging bag roll on the conveyor belt 2 is moved by starting the conveyor roller 1. When the vacuum packaging bag roll moves to the position of the straightening mechanism 3, the straightening mechanism 3 straightens the vacuum packaging bag roll so that the vacuum packaging bag roll is parallel to the moving direction of the conveyor belt 2.

[0034] In use, the eccentric wheel 38 is first rotated by the straightening motor 31 to control the position of the rotating plate 37, so that the rotating plate 37 is lowered to the lowest position and the straightening roller 35 is positioned above the conveyor belt 2. Then, the non-flush end of the vacuum packaging bag roll first contacts the straightening roller 35. The straightening roller 35 is used to limit the non-flush end of the vacuum packaging bag roll. Under the conveying action of the conveyor belt 2, the non-flush end of the vacuum packaging bag roll gradually approaches the straightening roller 35 until the vacuum packaging bag roll is parallel to the conveyor belt 2. Then, the straightening motor 31 is used to move the rotating plate 37 to the highest position.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
