DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0049] Please refer to Figures 1-7 The present application provides the following technical solutions:

[0050] A continuous packaging bag transfer mechanism includes a bag body conveying unit 1 and a bag body transfer unit 2. The bag body conveying unit 1 can convey the bag body queue 100, and the conveying direction is parallel to the length direction of the bag body queue 100. The bag body transfer unit 2 is arranged on one side of the bag body conveying unit 1, and can clamp and transfer the bag body 101.

[0051] It should be noted here that in the continuous packaging bag processing process, a film roll is first processed into a bag body. This processing process heats the continuous film material in an array position to form a space for filling one by one, and then cuts it at the heat sealing position. After cutting, the bag body 101 is immediately transferred.

[0052] The bag body conveying unit 1 conveys the bag body queue 100 just cut. Therefore, the bag body conveying unit 1 needs to consider how to make the discontinuous bag body queue 100 continue to advance. The bag body conveying unit 1 of the present solution includes at least one support member 11, which can support one side of the bag body queue 100. A negative pressure member 12 is arranged on the support member 11, which can form a negative pressure on one side of the support member 11 towards the bag body queue 100.

[0053] The present solution uses the combination of the negative pressure member 12 and the support member 11 to provide vertical support force to the bag body. Then, the negative pressure member 12 forms a negative pressure between the support member 11 and the bag body, which prevents the bag body from falling and guides the bag body to the discharge direction by the force of the negative pressure. Thus, the transmission of the entire bag body queue 100 is formed. At the same time, the bag body transfer unit 2 grabs and transfers the bag body 101 conveyed by the support member 11, so that the transfer process of the packaging bag in the production line can be realized.

[0054] On the basis of the above-mentioned embodiments, please refer to Figure 7The support member 11 comprises a support plate 111 and a support slide 112. The support plate 111 is vertically arranged as a whole, and comprises a straight plate part and a guide plate. The straight plate part is a vertically arranged straight plate body, and the side of the straight plate part facing the support slide 112 is a vertical plane. The straight plate part is used to provide vertical support for the bag body, and also serves as a baffle space structure formed by negative pressure. The guide plate is in the shape of a bent plate, and is connected to the straight plate part. The guide plate is located on the side of the straight plate part facing the feeding direction of the bag body, i.e. the guide plate is located on the feeding side of the support plate 111. The bending direction of the guide plate is towards the support slide 112. The support slide 112 is fixedly arranged at the lower end of the support plate 111, and the end of the support slide 112 away from the negative pressure member 12 is provided with a flared structure.

[0055] The bottom edge of the bag body queue 100 enters the support slide 112, and the support slide 112 provides support for the bottom. The negative pressure member 12 supplies airflow to the support plate 111, and the airflow forms negative pressure on the straight plate part of the support plate 111, so that the bag body is adsorbed towards the straight plate part, and the problem of the bag body toppling over does not occur. In combination with the structure of the guide plate which is approximately half of a flared opening, the bag body entering the straight plate part of the support plate 111 is more easily guided.

[0056] On the basis of the above-mentioned embodiments, the support plate 111 is provided with air outlets 113 which are horizontally arranged towards the conveying direction of the bag body. The air outlets 113 are arranged at the connection between the guide plate and the straight plate part. The air outlets 113 are arranged in an array in the vertical direction. The negative pressure member 12 is a gas pump or a gas pump connecting pipe, and the air outlet end of the negative pressure member is in communication with the air outlets 113. The negative pressure member 12 is arranged on the side of the support plate 111 away from the bag body queue 100.

[0057] The negative pressure member 12 supplies compressed airflow to the air outlets 113, and the airflow supplied by the negative pressure member 12 forms negative pressure between the support plate 111 and the bag body queue 100, so that the bag body is conveyed while being prevented from toppling over. That is, the bag body is tightly attached to the negative pressure member by negative pressure adsorption, and is guided to move forward under the action of the negative pressure airflow.

[0058] On the basis of the above-mentioned embodiments, two support members 11 are arranged side by side, and the two support members 11 are arranged in the conveying direction of the bag body. Only one negative pressure member 12 is needed, and the negative pressure member 12 is arranged on the support member 11 at the front end in the conveying direction of the bag body.

[0059] On the basis of the above-mentioned embodiments, in order to ensure the posture of the bag body queue 100 before entering the support member 11, the bag body conveying unit 1 further comprises a positioning member 13 arranged at the feeding end of the bag body conveying unit 1.

[0060] The positioning member 13 comprises two positioning plates, and a space is left between the two positioning plates, which corresponds to the bag body queue 100; the edge portion of the two positioning plates away from the support member 11 is provided with a flared structure. The bag body queue 100 can pass between the two positioning plates, and the bag body queue 100 can be ensured to keep a substantially vertical posture to enter the position where the support member 11 is located.

[0061] On the basis of the above-mentioned embodiment, the two positioning plates of the positioning member 13, one of which is a fixed plate, and the other of which is a movable plate, the fixed plate can be arranged on the support structure of the entire transfer mechanism, and the movable plate can be arranged to be adjustable to be directed toward or away from the fixed plate. The adjustment structure can be realized by selecting the prior art, such as a screw nut adjustment structure, and the specific adjustment structure is not the key point of the present scheme, and will not be described here.

[0062] On the basis of the above-mentioned embodiment, the bag body transfer unit 2 comprises a clamping assembly 21 and a transfer assembly 22.
