Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a bag-supporting device for preventing bag opening from being polluted. Background Art

[0002] In the process of food packaging, especially for semi-fluid or solid food with slurry on the surface, since the surface of the food has viscous slurry or oil, it is easy to contaminate the bag mouth during the bagging process, causing inconvenience in subsequent sealing. It needs to be manually wiped before sealing, which seriously affects the bagging efficiency of the product. There is currently no good solution in the industry. Utility Model Content

[0003] To solve the above technical problems, the utility model discloses a bag-opening prevention contamination device, comprising a feeder and a bag-opening prevention device, wherein the bag-opening prevention device is movably arranged on the outside of the feeder, and the feeder comprises a bottom plate and side panels, wherein the side panels extend upward from both sides of the bottom plate.

[0004] Furthermore, the mouth opener is an arc-shaped or annular structure.

[0005] Furthermore, the side enclosures extend upward from both sides of the bottom plate and form an annular feeding opening above the front side of the bottom plate.

[0006] Furthermore, the feeder is connected to a first driving unit, and the mouth opener is connected to a second driving unit.

[0007] Furthermore, a support plate is provided on one side of the feeder, a first suction cup is provided at the bottom of the support plate, and a second suction cup is provided above the support plate through a third driving unit.

[0008] Furthermore, the first driving unit, the second driving unit and the third driving unit are air cylinders, oil cylinders or linear modules.

[0009] The beneficial effects of the utility model are:

[0010] The bag-opening device of the utility model opens the bag opening of the packaging bag by means of a mouth-opening device arranged on the outside of the feeder, and then feeds the material into the packaging bag through the feeder. Since the material and the bag opening are separated by the mouth-opening device, slurry or oil on the surface of the material will not be contaminated on the bag opening, thereby improving the efficiency of subsequent sealing and the entire packaging process.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Embodiment 1

[0023] like Figure 1-2 As shown, the bag-opening prevention contamination device in this embodiment includes a feeder 1 and a mouth-opening device 2. The mouth-opening device 2 can be movably arranged on the outside of the feeder 1. The feeder 1 includes a bottom plate 11 and side panels 12. The side panels 12 extend upward from both sides of the bottom plate 11. The mouth-opening device 2 is an arc-shaped structure and is located at the bottom of the feeder 1. Embodiment 2

[0024] like Figure 3-4 As shown, in this embodiment, the side enclosures 12 extend upward from both sides of the bottom plate 11 and form an annular feeding opening 13 above the front side of the bottom plate 11; the mouth support device 2 is an annular structure and is sleeved on the outside of the feeder 1. Embodiment 3

[0025] like Figure 5 As shown, in this embodiment, the feeder 1 is connected to a first driving unit 3, and the mouth-opening device 2 is connected to a second driving unit 4; a support plate 5 is provided on one side of the feeder 1, and a packaging bag 6 is located on the support plate 5. A first suction cup 7 is provided at the bottom of the support plate 5, and a second suction cup 8 is provided above the support plate 5 through a third driving unit 9. Among them, the first driving unit 3, the second driving unit 4 and the third driving unit 9 can be driven by a cylinder, an oil cylinder or a linear module.

[0026] When in use, the first suction cup 7 and the second suction cup 8 respectively suck the upper and lower sides of the bag opening of the packaging bag 6, and the third driving unit 9 moves upward, driving the second suction cup 8 to move upward and open the bag opening, and then the second driving unit 4 first sends the mouth opener 2 into the bag opening, and the first driving unit 3 then sends the feeder 1 into the mouth opener 2, so that the mouth opener 2 separates the feeder 1 from the bag opening.

[0027] When loading, the material enters the packaging bag 6 along the feeder 1, and the slurry or oil on the surface of the material will not be contaminated on the bag opening. Therefore, the bag opening does not need to be wiped later and can be directly sealed, thereby improving the production efficiency of the entire packaging process.

[0028] After bagging is completed, the feeder 1 is withdrawn first, and then the mouth opener 2 is withdrawn to prepare for the next bagging.

[0029] According to different material types and packaging requirements, the bag-supporting device of the utility model can be used in conjunction with existing vertical packaging machines, horizontal (pillow) packaging machines, vacuum packaging machines and other packaging machines, which is beneficial to improving product packaging efficiency.

[0030] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
