Description

Technical Field

[0001] This utility model relates to the field of feeding mechanisms, and specifically to a feeding mechanism for transporting packaging bags. Background Technology

[0002] Packaging bags, as an indispensable packaging material in modern industrial production and daily life, are widely used in food, pharmaceuticals, daily chemicals, logistics, and other fields. Among them, plastic packaging bags occupy a core position in automated packaging production lines. With the advancement of Industry 4.0 and intelligent manufacturing, the packaging industry's demands for production efficiency, precision, and flexibility are increasing, making the bag transfer and feeding process a key technology affecting the overall production line efficiency.

[0003] Existing bag conveying mechanisms typically consist of a conveying component, an adsorption and positioning component, and a heat-sealing component. The conveying component often uses a belt or chain drive structure, driven by a motor to achieve intermittent or continuous conveying of the bags; the adsorption and positioning component generally uses vacuum adsorption to adsorb the surface of the bags, combined with a mechanical limiting structure to achieve initial positioning; the heat-sealing component is integrated at the end of the conveying mechanism, using heating elements to melt and seal the opening of the bags.

[0004] However, existing feeding mechanisms still have the following technical defects in practical applications: the transmission feeding mechanism is generally positioned by vacuum adsorption of the packaging bag, but the vacuum adsorption setting of the existing feeding mechanism is relatively simple, and the end of the feeding mechanism is usually equipped with a heat sealing component for heat sealing. Therefore, the end of the packaging bag extending towards the heat sealing component usually lacks corresponding vacuum adsorption positioning, and is prone to positioning deviation due to uneven distribution of adsorption force, which affects the subsequent heat sealing packaging. In addition, the existing feeding mechanism has a poor gripping and positioning effect on the packaging bag. When the external filling claws penetrate the packaging bag to release the material, the packaging bag is prone to deviation, which affects the effect of use. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a feeding mechanism for transporting packaging bags, so as to solve the technical problem that the existing feeding mechanism has poor transport and positioning effect on packaging bags, which affects the subsequent filling and use of packaging bags.

[0006] The objective of this utility model is achieved through the following means:

[0007] The feeding mechanism for transporting packaging bags includes a linear module and a feeding plate mounted on the linear module. The linear module can drive the feeding plate to reciprocate along the linear module via a sliding seat. A feeding exhaust shell is connected to the feeding plate. One end of the feeding exhaust shell forms a vacuum adsorption end. A heat-sealing groove for heat sealing is opened in the middle of the vacuum adsorption end. An air extraction cavity is formed inside the vacuum adsorption end, and an air extraction pipe communicating with the air extraction cavity is opened on the side of the vacuum adsorption end. A first adsorption part and a second adsorption part are formed on the vacuum adsorption end. The first adsorption part and the second adsorption part are distributed on both sides of the heat-sealing groove, and both the first adsorption part and the second adsorption part are provided with vacuum adsorption holes communicating with the air extraction cavity. A positioning component for positioning the packaging bag is connected to the end of the feeding exhaust shell away from the vacuum adsorption end.

[0008] Furthermore, as described above, a receiving platform is formed on the feeding exhaust housing, and the feeding exhaust housing is installed on the feeding plate, so that the feeding plate can drive the feeding exhaust housing to reciprocate along the linear module.

[0009] By forming a receiving platform on the feeding exhaust housing and installing the feeding exhaust housing on the feeding plate, the feeding plate can drive the feeding exhaust housing to move back and forth along the linear module. This ensures that the feeding exhaust housing moves synchronously and stably with the feeding plate during the transmission process, thereby stably receiving the packaging bag and avoiding the packaging bag from shifting during the transmission stage due to unstable movement. This provides a basic guarantee for subsequent positioning and heat sealing.

[0010] Furthermore, as described above, one end of the feeding plate is connected to the sliding seat, and the other end of the feeding plate is connected to a sliding member. The sliding direction of the sliding member is flush with the extension direction of the linear module. The sliding member consists of a slide rail and a slider. The end of the feeding plate is connected to the slider, so that the sliding seat can drive the feeding plate to reciprocate.

[0011] One end of the feeding plate is connected to the sliding seat, and the other end is connected to the slider through a pad. The sliding direction of the slide rail is flush with the linear module, which enhances the stability of the feeding plate's reciprocating movement, reduces shaking or skew during movement, and thus improves the positioning accuracy of the packaging bag transmission.

[0012] Furthermore, as described above, the heat-sealing groove is located in the middle of the vacuum adsorption end, and the opening end of the heat-sealing groove extends through to the upper surface of the vacuum adsorption end. Both sides of the heat-sealing groove extend through to the sides of the feeding exhaust shell. A heat-sealing assembly for heat-sealing plastic packaging bags is provided inside the heat-sealing groove. The heat-sealing assembly includes a heat-sealing strip and a connecting plate. The heat-sealing strip is paired and installed in the heat-sealing groove through the connecting plate, and the heating part of the heat-sealing strip is exposed on the upper surface of the vacuum adsorption end.

[0013] The heat-sealing groove is located in the middle of the vacuum adsorption end, providing a precise installation space for the heat-sealing assembly. The heat-sealing assembly uses a connecting plate to install the heat-sealing strip into the heat-sealing groove, with the heating part of the heat-sealing strip exposed on the upper surface of the vacuum adsorption end. This ensures direct contact with the packaging bag during heat sealing, guaranteeing the heat-sealing effect. By providing a heat-sealing groove for installing the heat-sealing assembly on the vacuum adsorption end, the vacuum adsorption end ensures the adsorption and positioning effect of the packaging bag through the first and second adsorption parts. At the same time, after the packaging bag is filled with product, it can cooperate with an external heat-sealing mechanism and heat-sealing strip to melt and seal the packaging bag. The setting of the first and second adsorption parts ensures the stability and reliability of the heat sealing of the packaging bag.

[0014] Furthermore, as described above, the first adsorption portion and the second adsorption portion are distributed on both sides of the heat-sealing strip.

[0015] The first and second adsorption parts are distributed on both sides of the heat-sealing strip, so that the packaging bag can be vacuum adsorbed on both sides of the heat-sealing area. The adsorption force is more evenly distributed, which effectively solves the positioning offset problem caused by the lack of adsorption at the end of the packaging bag extending towards the heat-sealing component in the prior art, and improves the positioning stability of the packaging bag under heat sealing.

[0016] Further, as described above, the positioning component includes an adjusting plate, adjusting bolts, and a rubber strip. One end of the rubber strip is bent to form a support portion, which extends toward the vacuum adsorption end. The other end of the rubber strip is bent to form a connecting portion. The adjusting plate is installed on the side of the feeding exhaust housing away from the vacuum adsorption end. A connecting groove is provided on the adjusting plate, and the connecting portion extends toward the adjusting plate. The connecting portion is connected to the connecting groove by adjusting bolts.

[0017] The positioning component consists of an adjusting plate, adjusting bolts, and a rubber strip. The support part of the rubber strip extends towards the vacuum suction end, which can hold and position the packaging bag. The adjusting plate has a connecting groove and is connected to the connecting part of the rubber strip through the adjusting bolt, so that the position of the rubber strip can be adjusted to meet the packaging positioning needs of packaging bags of different sizes, enhancing the flexibility and effectiveness of holding and positioning, and preventing the packaging bag from shifting due to lack of holding during filling.

[0018] Furthermore, as described above, two adhesive strips are provided. The two adhesive strips are connected to the adjustment plate through a connecting part and can be adjusted to move closer or further apart along the adjustment groove. The support parts of the two adhesive strips extend along the upper surface of the feeding exhaust shell towards the vacuum adsorption end.

[0019] Two adhesive strips are installed, and the spacing between them is adjusted by adjusting the groove. The support parts of the two adhesive strips extend along the upper surface of the feeding exhaust shell towards the vacuum adsorption end, holding the packaging bag from both sides. When the external filling claws penetrate the packaging bag to release the material, the two adhesive strips further enhance the holding and limiting, ensuring the stability and reliability of filling when the bag is inserted, and improving the use effect during the filling stage.

[0020] The beneficial effects of this utility model are as follows: By setting a first adsorption part and a second adsorption part at the vacuum adsorption end of the feeding exhaust shell, and distributing them on both sides of the heat-sealing groove, and opening vacuum adsorption holes communicating with the exhaust cavity respectively, the packaging bag can obtain uniform adsorption force on both sides of the heat-sealing area. This solves the problem of lack of vacuum adsorption positioning at the end of the packaging bag extending towards the heat-sealing component in the prior art, and avoids positioning deviation caused by uneven distribution of adsorption force, thereby improving the accuracy of subsequent heat-sealing operations and ensuring the quality of packaging bag conveying and heat-sealing. By setting a positioning component for packaging bag positioning at the end of the feeding exhaust shell away from the vacuum adsorption end, the clamping and positioning effect of the feeding mechanism on the packaging bag can be enhanced. When the external filling claws penetrate the packaging bag for material release, the positioning component can play a guiding role, which can effectively reduce the deviation of the packaging bag, improve the conveying and positioning stability of the packaging bag by the feeding mechanism, and ensure the smooth progress of subsequent filling operations.

The linear module 100 can be driven by a sliding seat 101 to reciprocate along the linear module 100. A feeding exhaust shell 300 is connected to the feeding plate 200.

[0033] By forming a receiving platform on the feeding exhaust housing 300 and installing the feeding exhaust housing 300 on the feeding plate 200, the feeding plate 200 can drive the feeding exhaust housing 300 to reciprocate along the linear module 100. This ensures that the feeding exhaust housing 300 moves synchronously and stably with the feeding plate 200 during the transmission process, thereby stably receiving the packaging bag and avoiding the packaging bag from shifting during the transmission stage due to unstable movement. This provides a basic guarantee for subsequent positioning and heat sealing.
