AI Technical Summary
In existing technologies, during high-speed continuous production, the outer packaging bag undergoes shape changes due to friction during long-distance transportation, affecting the success rate of unpacking. Furthermore, the disinfectant's action time is insufficient, making it difficult to achieve high-speed uninterrupted production.
A rolling film-pulling mechanism is used to clamp the sides of the packaging material and shape the outer bag. The conveyor track ensures that the disinfectant can be fully applied. Combined with the L-shaped conveyor track and positioning blocks, the packaging material is stably conveyed at the bag cutting and unpacking station.
This improved the success rate of unpacking, enabling high-speed, continuous, and stable production of spray disinfection and unpacking, ensuring disinfection effectiveness and equipment reliability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, and in particular to an unpacking system. Background Technology
[0002] Before removing RTU (Ready to use) packaging materials, the outer bag needs to be disinfected by spraying disinfectant on the surface of the bag. After spraying, the disinfectant needs a certain amount of time to act on the surface of the outer bag (usually about 3 minutes). Therefore, for high-speed continuous production lines, it is necessary to meet both high-speed uninterrupted production and buffer disinfection requirements.
[0003] The buffer disinfection process requires a long conveyor belt. During the process of transporting the outer bag of the packaging material to the outer bag unpacking machine on the long conveyor belt, the friction will inevitably cause the shape of the outer bag to change, deviating from the shape that was manually sorted during feeding (the sorted shape is suitable for the outer bag unpacking machine to cut the bag). When it is sent to the outer bag unpacking machine at this time, the success rate of automatic unpacking will be greatly reduced. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a packaging unpacking system with a simple structure that can sort out the outer bag of the packaging material and improve the success rate of unpacking.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A packaging unpacking system includes a conveyor track, a disinfection station located at the inlet end of the conveyor track, and a bag cutting and unpacking station located at the outlet end of the conveyor track. The outlet end of the conveyor track is also provided with a rolling film pulling mechanism upstream of the bag cutting and unpacking station. The rolling film pulling mechanism is used to clamp the side of the packaging material for bag sorting.
[0007] As a further improvement to the above technical solution: the rolling film pulling mechanism includes a first roll bag roller shaft disposed on one side of the conveying track and a second roll bag roller shaft disposed above the first roll bag roller shaft. The second roll bag roller shaft and the first roll bag roller shaft can be close to each other to clamp the side of the packaging material for bag handling.
[0008] As a further improvement to the above technical solution: the first roll bag roller is mounted on the first lifting seat, and the second roll bag roller is mounted on the second lifting seat.
[0009] As a further improvement to the above technical solution: the second lifting seat is provided with a pressure plate for pressing the packaging material.
[0010] As a further improvement to the above technical solution: the second lifting seat is also provided with a first guide plate, the first guide plate being tangent to the bottom of the second roll bag roller, and the first lifting seat is provided with a second guide plate, the second guide plate being tangent to the top of the first roll bag roller.
[0011] As a further improvement to the above technical solution: the first lifting seat is also provided with a positioning roller shaft, and the other side of the conveying track is provided with a track rail.
[0012] As a further improvement to the above technical solution: the conveying track is uniformly provided with multiple packaging material positioning blocks along the conveying direction.
[0013] As a further improvement to the above technical solution: the conveying track is arranged in an L-shape.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] The unpacking system disclosed in this utility model involves manually arranged packaging materials placed on a conveyor track and transported to a disinfection station. A layer of disinfectant is sprayed onto the surface of the packaging material, which is then transported to a rolling film-pulling mechanism. Sufficient time is given for the disinfectant to act, ensuring effective disinfection. The rolling film-pulling mechanism clamps the sides of the packaging material to straighten out any deformation caused by friction during long-distance transport. The straightened packaging material is immediately transported to a bag-cutting and unpacking station for cutting and removing the outer bag. This improves the success rate of unpacking and enables high-speed, continuous, and stable production from spray disinfection to unpacking.
[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Figures 1 to 4 An embodiment of the unpacking system of this utility model is shown. The unpacking system of this embodiment includes a conveyor track 1 (e.g., a mesh belt type conveyor track 1), a disinfection station 2 located at the inlet end of the conveyor track 1, and a bag cutting and unpacking station 3 located at the outlet end of the conveyor track 1. A rolling film pulling mechanism 4 is also provided upstream of the bag cutting and unpacking station 3 at the outlet end of the conveyor track 1. The rolling film pulling mechanism 4 is used to clamp the side of the packaging material 5 for bag sorting.
[0028] In this embodiment of the unpacking system, manually prepared packaging material 5 is placed on conveyor track 1 and transported to disinfection station 2, where a layer of disinfectant is sprayed onto its surface. The material is then transported by conveyor track 1 to rolling film-pulling mechanism 4, allowing sufficient time for the disinfectant to act and ensuring disinfection effectiveness. Rolling film-pulling mechanism 4 clamps the sides of packaging material 5 to straighten out any deformation caused by friction during long-distance transport. The straightened packaging material 5 is then immediately transported to bag-cutting and unpacking station 3 for cutting and removing the outer bag, improving the success rate of unpacking and achieving high-speed, continuous, and stable production from spray disinfection to unpacking.
[0029] See details Figure 3 and Figure 4 Furthermore, in this embodiment, the rolling film-pulling mechanism 4 includes a first roll roller 42 located on one side of the conveying track 1 (corresponding to the side where the outer bag of the packaging material 5 is cut off) and a second roll roller 41 located above the first roll roller 42. The second roll roller 41 and the first roll roller 42 can approach each other to clamp the side of the packaging material 5 for bag sorting. After the packaging material 5 is conveyed into place, the first roll roller 42 and the second roll roller 41 approach the side of the packaging material 5 and then roll the film and roll the bag to sort the side of the outer bag of the packaging material 5. Preferably, one of the first roll roller 42 and the second roll roller 41 is an active roller and the other is a passive roller (i.e., passively rotated under the drive of the outer bag), or both the first roll roller 42 and the second roll roller 41 are active rollers and rotate synchronously, but the structure is more complex and the cost is higher. After the bag sorting is completed, the first roll bag roller 42 and the second roll bag roller 41 are reset and moved away from each other, thereby releasing the packaging material 5. The packaging material 5 can then be conveyed to the downstream bag cutting and unpacking station 3.
[0030] Furthermore, in this embodiment, the first roll bag roller 42 is mounted on the first lifting seat 44, and the second roll bag roller 41 is mounted on the second lifting seat 43. That is, the first roll bag roller 42 and the second roll bag roller 41 clamp or release the packaging material 5 by lifting. The structure is simple and has good reliability.
[0031] Furthermore, in this embodiment, the second lifting seat 43 is provided with a pressure plate 45 for pressing the packaging material 5. The pressure plate 45 can descend with the second lifting seat 43, thereby pressing the packaging material 5 onto the conveying track 1 to prevent displacement and facilitate the rolling of the first roll bag roller 42 and the second roll bag roller 41 to pull the film and roll the bag.
[0032] Furthermore, in this embodiment, the second lifting seat 43 is also provided with a first guide plate 46, which is tangent to the bottom of the second bag rolling roller 41. The first lifting seat 44 is provided with a second guide plate 47, which is tangent to the top of the first bag rolling roller 42. By setting the first guide plate 46 and the second guide plate 47 for guidance, the bag edge can be prevented from curling during the film pulling and bag rolling process, or in other words, the outer bag side can be prevented from wrapping around the first bag rolling roller 42 and the second bag rolling roller 41, further improving the reliability of the equipment.
[0033] Furthermore, in this embodiment, the first lifting seat 44 is also provided with a positioning roller 48, and the other side of the conveying track 1 is provided with a track rail 11. The positioning roller 48 can cooperate with the track rail 11 to achieve lateral positioning of the packaging material 5, and prevent the packaging material 5 from shifting when the first roll-up roller 42 and the second roll-up roller 41 roll the film and roll the bag.
[0034] See details Figure 2 and Figure 3 In this embodiment, the conveying track 1 is uniformly provided with multiple packaging material positioning blocks 12 along the conveying direction. The packaging material 5 can be longitudinally positioned by two adjacent packaging material positioning blocks 12, and the stable conveying of the packaging material 5 can be achieved at the same time. The structure is simple and reliable.
[0035] See details Figure 1 In this embodiment, the conveyor track 1 is arranged in an L-shape. Since the conveyor track 1 needs to be of sufficient length to ensure the disinfectant's contact time, the L-shaped arrangement, compared to a straight arrangement, helps to reduce the factory area occupied by the conveyor track 1 and save costs.
[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
