Description

Technical Field

[0001] The utility model belongs to the technical field of packaging machinery, and in particular relates to a bag opening stretching and flattening device for a packaging bag. Background Art

[0002] With the rapid development of the packaging industry, the requirements for packaging efficiency and quality are also constantly increasing. In the automatic packaging production line, the preparation and sealing of packaging bags is one of the key steps, especially the processing of the bag mouth, which directly affects the sealing and appearance of the packaging. The traditional packaging bag mouth processing method often requires manual intervention, which is not only inefficient, but also difficult to ensure consistent bag mouth processing quality.

[0003] After the packaging bag is filled with materials, during the loading process, the packaging bag is tied to the mouth of the barrel, resulting in irregular wrinkles on the mouth of the packaging bag after loading is completed. If it is an automated equipment, there is no human to tidy up the bag mouth during the subsequent transportation of the packaging bag to the sewing machine. This will cause the mouth of the packaging bag sent to the sewing machine to have irregular wrinkles. When the sewing machine is sewing, there will be leakage production accidents or irregular sewing, which directly affects the automated production of the equipment. Therefore, a bag mouth stretching and flattening device for the packaging bag is developed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, provides a packaging bag mouth stretching and flattening device, comprising:

[0028] The transport mechanism 100 includes a support leg 101 , a connecting beam 102 is fixedly mounted on the outer wall of the support leg 101 , a connecting shaft 103 is fixedly mounted on the outer wall of the connecting beam 102 , and a roller 104 is fixedly mounted on the outer wall of the connecting shaft 103 .

[0029] Specifically, a stretching mechanism 200 is disposed above the transport mechanism 100 .

[0030] According to the working principle of the above structure when in use, before the roller 104 transports the packaging bag filled with raw materials to the baler, the air pump 206 is extended and retracted, driving the fork 207 to extend and retract, and the fork 207 straightens the wrinkles at the bag opening and pulls the bag opening to a horizontal state.

[0031] In summary, the beneficial effect of the above structure is that the air pump 206 controls the extension and retraction of the fork 207, which can effectively straighten the bag mouth filled with raw materials and keep it in a horizontal state, thereby improving the efficiency and quality of subsequent packaging operations. This process not only simplifies the operating steps and reduces labor costs, but also ensures the stability and safety of the packaging bags during transportation, which helps to improve the work efficiency of the entire packaging production line.

[0032] Example 2

[0033] Reference Figure 4 and Figure 5 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a stretching mechanism for pulling the bag opening.

[0034] Specifically, the stretching mechanism 200 includes a fixed base plate 201, a connecting beam 102 is fixedly connected to the outer wall of the fixed base plate 201, a motor 202 is fixedly installed on the outer wall of the fixed base plate 201, a slide groove 208 is provided on the outer wall of the motor 202, a limiting slider 209 is sleeved on the inner wall of the slide groove 208, and a support block 204 is fixedly installed on the outer wall of the limiting slider 209.

[0035] Furthermore, a lifting shell 205 is fixedly installed on the outer wall of the support block 204, a rack 211 is fixedly installed on the inner wall of the lifting shell 205, a transmission gear 210 is fixedly installed on the output end of the motor 202, the transmission gear 210 is meshed with the rack 211, a compression spring telescopic rod 203 is fixedly installed on the outer wall of the support block 204, an air pump 206 is fixedly installed on the outer wall of the support block 204, and a fork 207 is fixedly installed on the outer wall of the air pump 206.

[0036] According to the working principle of the above structure during use, when the packaging bag passes through the device, the motor 202 will drive the transmission gear 210 to rotate, and the transmission gear 210 will drive the rack 211 to rise or fall, thereby driving the support block 204 to move up and down, and the support block 204 will drive the air pump 206 to move up and down, and the compression spring telescopic rod 203 will support the block 204 to ensure the smooth operation of the support block 204.

[0037] In summary, the beneficial effects of the above structure are as follows: the transmission gear 210 is driven to rotate by the motor 202, and the up and down movement of the support block 204 is controlled by the rising or falling movement of the rack 211; the support block 204 is then adjusted up and down by the air pump 206, so that the device can be suitable for strapping belts of different sizes; the compression spring telescopic rod 203 provides stable support for the support block 204, ensuring the smooth operation of the entire system, effectively supporting the stability and safety of the packaging bag during the packaging process, and improving the packaging efficiency.
