Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to a pre-opening bag module and an automatic packaging machine having the pre-opening bag module. Background Technology

[0002] Packaging refers to the technical means of wrapping and protecting products using certain technical methods. In various manufacturing industries today, it is necessary to wrap and protect products with packaging bags in order to improve product protection and reduce the probability of products being invaded by dust and rainwater.

[0003] In existing packaging production, the process from bag making to bagging can mostly be automated through mechanization. Rolls of material bags are heat-cut and sealed to form single-sided open packaging bags. After bag making, a robotic arm grips the bag and opens the opening for bagging. However, under normal circumstances, the two layers of film on the material bag are tightly bonded, making it difficult for a robotic arm to open the bag opening. Existing pre-opening mechanisms are complex in structure and lack versatility for various bag sizes. Utility Model Content

[0004] Therefore, in response to at least one of the above problems, this utility model provides a pre-opening bag module and an automatic packaging machine.

[0005] This utility model is achieved using the following solution:

The material bag has a two-layer film structure. The pre-opening bag module is located between the two layers of film of the material bag. The pre-opening bag module includes a base and an extension block. The extension block is telescopically connected to the base.

[0007] In one embodiment, the base has an elongated hole, and the extension block has an extension block connection hole. A connector passes through the elongated hole and connects to the extension block connection hole, thereby telescopically connecting the extension block to the base.

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-10 This embodiment provides an automatic packaging machine 1, including a material storage and feeding assembly 20, a pre-opening bag module 10, a heat-cutting assembly 50, a clamping assembly 30, and a hook-and-pull assembly 40. The material storage and feeding assembly 20 is used to store and transport material bags 21. The automatic packaging machine 1 is used to package products using the material bags 21 as packaging material, particularly referring to... Figure 3 as well as Figure 4 The material bag 21 is conveyed along the M direction. The material bag 21 has a two-layer film structure, for example, the two-layer film structure is formed by folding a single layer film along the centerline.

[0030] The bag 21 first passes through the pre-opening module 10, which is located between the two layers of film on the bag 21. When the bag 21 is conveyed along the M direction through the pre-opening module 10, the pre-opening module 10 can separate the two layers of film on the bag 21, thereby forming a gap between the two layers of film to open the bag opening at the side end of the bag 21. This achieves a good pre-opening effect and high production efficiency.

[0031] After passing through the pre-opening module 10, the material bag 21 is thermally cut and sealed by the hot-cutting component 50 to form a packaging bag structure of suitable size. At this time, the packaging bag structure has an opening on one side. The packaging bag structure is conveyed to the next process for product packaging by the clamping component 30 clamping the bag edge and the hooking component 40 hooking the bag opening. The pre-opening module 10 has a simple structure, good pre-opening effect, and facilitates the insertion of the bag opening mechanism for product packaging at the bag opening.

[0032] The pre-opening bag module 10 includes a base 11, an intermediate block 12, and an extension block 13. The extension block 13 is telescopically connected to the base 11, thus the pre-opening bag module 10 has high versatility for various sizes of bags 21 and has a simple structure.

[0033] Reference Figure 4-10 The base 11 has an elongated hole 114, and the extension block 13 has an extension block connection hole 131. A connector passes through the elongated hole 114 and connects to the extension block connection hole 131. For example, a screw passes through the elongated hole 114 and connects to the extension block connection hole 131, thereby telescopically connecting the extension block 13 to the base 11 to adapt to different sizes of material bags 21. Of course, in other embodiments, the extension block 13 can also be telescopically connected to the base 11 in other ways, such as by a telescopic cylinder.

[0034] In this embodiment, the bottom surface of the base 11 is provided with an extension mounting groove 117, and the extension block 13 and the intermediate block 12 are installed in the extension mounting groove 117, so that the bottom surface of the extension block 13 and the intermediate block 12 is flush with the bottom surface of the base 11, which is conducive to the smooth passage of the two layers of film of the material bag 21.

[0035] The extension block 13 extends along the length of the base 11, protruding beyond the extension mounting groove 117. The intermediate block 12 is mounted inside the extension block 13. Both the extension block 13 and the intermediate block 12 are provided with clamping clearance openings, namely a first clamping clearance opening 132 and a second clamping clearance opening 122, respectively. At the same time, the base 11 is provided with a clearance cut 119. The first clamping clearance opening 132, the second clamping clearance opening 122, and the clearance cut 119 are used to avoid the grippers of the clamping assembly 30. Of course, in some embodiments, the intermediate block 12 may not be provided; or, the extension block 13 and the intermediate block 12 are an integral structure, that is, the extension block 13 is provided with both the first clamping clearance opening and the second clamping clearance opening.

[0036] In this embodiment, the intermediate block 12 is provided with an intermediate block connection hole 121, and the base 11 is provided with an intermediate block mounting hole 113, so that the intermediate block 12 can be mounted on the base 11 through a connector.

[0037] Reference Figure 4-10 The base 11 includes a base body 111, on which a guide surface 112 is provided. The guide surface 112 is inclined relative to the base body 111, so that when the bag 21 is conveyed along the M direction through the pre-opening module 10, the guide surface 112 can play a guiding role, and the bag 21 passes through more smoothly.

[0038] One end of the base 11 is provided with a base connection hole 116 to connect and install the pre-opening bag module 10 on the frame of the packaging machinery. One end of the base 11 is also provided with a hook avoidance groove 115 to avoid the hook of the hook assembly 40, thereby increasing the success rate of the hook assembly 40 hooking the bag opening.

[0039] The base 11 has a first rounded corner 118 on the side facing the direction of the material bag 21's movement, and the extension block 13 has a second rounded corner 133 on the side facing the direction of the material bag 21's movement, thus reducing the obstruction to the material bag 21 and allowing the material bag 21 to pass through more smoothly.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
