[0001] The present application relates to inkjet coding of packaging bags, and in particular to a baffle mechanism for fixing packaging bags. Background Art

[0002] After the powder product is put into the packaging bag, it needs to be printed with a mark and date. Usually, the packaging bag is transported to the coding position on the conveyor belt, and then the printing operation is completed by the inkjet printer.

[0003] Since the spraying distance of the printer nozzle is relatively fixed, when producing products with different packaging, it is necessary to adjust the position of the printer sensor and the nozzle according to the size of the packaging bag to make the size and position of the inkjet code appropriate. Utility Model Content

[0004] The purpose of the present application is to provide a mechanism that can adjust the position of the inkjet terminal according to the width of the packaging bag and make the nozzle perpendicular to the side of the packaging bag so as to effectively perform the coding operation.

[0005] To this end, according to the technical solution of the present application, a coding baffle mechanism is provided, which has a baffle, wherein the baffle has a guide portion located at the front and a clamping portion located at the rear, and an angle is formed between the guide portion and the clamping portion. The back side of the baffle is respectively connected to the first end of the first push rod and the first end of the second push rod, the second end of the first push rod is connected to the first base, and the second end of the second push rod is connected to the second base.

[0006] Wherein, the first push rod is connected to the guide portion. Further, the first push rod is provided with a first return spring, and the first return spring is provided between the guide portion and the first base.

[0007] Wherein, the second push rod is connected to the clamping portion. Further, a second return spring is arranged on the second push rod, and the second return spring is arranged between the clamping portion and the second base.

[0015] 100 baffle mechanism of inkjet printer, 110 baffle, 112 guide part, 114 clamping part, 116 printing hole, 120 first push rod, 122 first end, 124 second end, 130 second push rod, 132 first end, 134 second end, 136 second return spring, 140 first base, 150 second base DETAILED DESCRIPTION

[0016] The specific implementation of the present application is described below with reference to the accompanying drawings.

[0017] Reference Figure 1 The baffle mechanism 100 of the inkjet printer is arranged on the conveyor belt 20 of the packaging bag 10, and is used to abut against the side of the packaging bag 10 and can serve as a mounting bracket for the nozzle. The conveying direction of the packaging bag 10 on the conveyor belt 20 is as follows: Figure 1 The term "lateral" refers to the direction substantially perpendicular to the conveying direction of the bag in the plane consistent with the conveyor belt. The term "width" refers to the dimension in the lateral direction. The term "up and down" or "vertical" refers to the direction perpendicular to the plane of the conveyor belt.

[0018] In the context of this application, the term "front" refers to the direction opposite to the conveying direction of the packaging bag, and the term "rear" refers to the direction consistent with the conveying direction of the packaging bag. The term "front side" or "front side" refers to the direction facing the packaging bag in the transverse direction, and the term "back side" or "back side" refers to the direction opposite to the front side.

[0019] The baffle mechanism 100 of the inkjet printer has a baffle 110 for guiding and clamping the packaging bag 10. The baffle 110 has a guide portion 112 located at the front, which faces the packaging bag 10 and has an angle deflected toward the back side relative to the transmission direction, so as to present an opening-like structure, thereby being able to accommodate packaging bags of different widths.

[0020] The baffle 110 also has a clamping portion 114 at the rear, which can be pressed against the side of the packaging bag 10 to make the side of the packaging bag 10 flat, thereby facilitating the coding operation. Therefore, the extending direction of the clamping portion 114 is preferably substantially consistent with the conveying direction of the packaging belt, thereby keeping the side of the packaging bag straight when clamping the packaging bag. According to specific practical application requirements, the clamping portion 114 can be installed with a certain angle deflected toward the positive side relative to the conveying direction of the packaging bag.

[0021] It can be seen that the guide portion 112 and the clamping portion 114 form an angle. The guide plate 112 and the clamping portion 114 can be two independent parts fixedly connected, for example, by welding, riveting or screwing, or can be integrally formed into a single part, for example, by stamping or other suitable sheet metal processing.

[0022] The clamping portion 114 is further provided with a printing hole 116 for accommodating a printing terminal for performing a coding operation on the side of the packaging bag 10 .

[0023] In addition, in one example, the upper and lower sides of the baffle plate also have curved portions, which can provide certain structural reinforcement and facilitate the movement of the baffle plate on the conveyor belt.

[0024] A first push rod 120 and a second push rod 130 are respectively disposed on the back side of the baffle 110 .

[0025] The first end 122 of the first push rod 120 is connected to the guide portion 112. In one example, the first push rod 120 and the guide portion 112 are in a non-movable connection, such as welding, riveting or threaded fixing. In another example, the first push rod 120 and the guide portion 112 are in a movable connection, such as through a pivot connection.

[0026] The second end 124 of the first push rod 120 is connected to the first base 140. In one example, the first push rod 120 is fixedly connected to the first base 140, such as by welding, riveting or threading. In another example, the first push rod 120 can slide relative to the first base 140 along the axial direction of the first push rod 120. For example, the first push rod passes through a through hole provided on the first base.

[0027] The first end 132 of the second push rod 130 is connected to the clamping portion 114. Similarly, in one example, the second push rod 130 is in an inactive connection with the clamping portion 114, such as welding, riveting or threading. In another example, the second push rod 130 is in an active connection with the clamping portion 114, such as through a pivot connection.

[0028] The second end 134 of the second push rod 130 is connected to the second base 150 , and the second push rod 130 can slide relative to the second base 150 along the axial direction of the second push rod 130 .

[0029] The first base 140 and the second base 150 can be fixed to the frame 30 of the conveyor. In one example, the first base 140 and the second base 150 are both fixed to the frame 30 in an inactive manner. In another example, at least one of the first base 140 and the second base 150 can rotate relative to a vertical axis.

[0030] In addition, a return spring is provided on at least one of the first push rod 120 and the second push rod 130. For example, the first push rod 120 is provided with a first return spring (not shown in the figure), and the first return spring is provided between the guide portion 112 and the first base 140. For another example, the second push rod 130 is provided with a second return spring 136, and the second return spring 136 is provided between the clamping portion 114 and the second base 150.

[0031] In order to adapt to packaging bags of different sizes, the baffle 110 needs to have a lateral translational freedom or a rotational freedom relative to a vertical axis, or both of the above-mentioned degrees of freedom. To this end, in different applications, the baffle can have the above-mentioned degrees of freedom and the rotation center axis can be adjusted by adjusting the connection mode between the first push rod and the baffle and the first base, and adjusting the connection mode between the second push rod and the baffle and the second base.

[0032] When the packaging bag 10 is conveyed to the guide portion 112, the guide portion 112 is squeezed under the drive of the conveyor belt 20, so that the baffle 110 moves to an appropriate position so that the clamping portion 114 contacts the packaging bag 10. At this time, the return spring is compressed, thereby applying elastic force to make the clamping portion 114 fit the packaging bag 10, which is convenient for the inkjet operation. When the inkjet operation is completed, the packaging bag 10 continues to move forward and leaves the baffle position, and the return spring resets the baffle mechanism.

[0033] In the above description, the details of the technical solution of the present application are explained. However, those skilled in the art will appreciate that the present application is not limited to the specific details listed in the above embodiments, but may vary within the scope defined by the claims.
