[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] In view of the problems in the background technology, the present invention proposes a packaging bag corner wrapping device, comprising:

[0035] Rack 10;

[0036] A transmission mechanism 20, the transmission mechanism 20 is horizontally fixed on the frame 10, and is used to transmit the material with the packaging bag;

[0037] A moving mechanism 30, the moving mechanism 30 comprises two transverse moving components 31 and two longitudinal moving components 32, the two transverse moving components 31 are respectively arranged on both sides of the frame 10, and the two longitudinal moving components 32 are both straddled and transmission-connected to the two transverse moving components 31;

[0038] Angle folding mechanism 40, the angle folding mechanism 40 comprises an X-axis moving pair 41, a Y-axis moving pair 42 and an angle plate 43, the X-axis moving pair 41 is connected to the frame 10, the Y-axis moving pair 42 is transmission-connected to the X-axis moving pair 41, and the angle plate 43 is transmission-connected to the Y-axis moving pair 42;

[0039] The tape winding mechanism 50 is connected to the longitudinal moving assembly 32 to drive the tape winding mechanism to apply the tape to the packaging bag.

[0040] Combined with reference Figures 1 to 5 As shown, the frame 10 can be made of sturdy and durable materials, serving as the basic structure of the entire device, providing a stable installation platform for other components, and ensuring the stability of the entire device. The transmission mechanism 20 is installed in the center of the frame 10, and can be composed of components such as a motor, a transmission chain or belt, and a roller. The motor can drive the belt or transmission chain to rotate, drive the material covered with the packaging bag to move, and smoothly transmit the material to the designated position. The moving mechanism 30 can include a lateral moving component 31 and a longitudinal moving component 32. The moving direction of the lateral moving component 31 is consistent with the transmission direction of the material, and the moving direction of the longitudinal moving component 32 is perpendicular to the transmission direction of the material. The two lateral moving components 31 can be fixed on both sides of the frame 10 through a gantry, and the two longitudinal moving components 32 are transmission-connected to the two lateral moving components 31. It should be noted that the lateral moving component 31 and the longitudinal moving component 32 can both be motor-driven synchronous belt rotation or motor-driven screw nut structure. The angle plate 43 of the angle folding mechanism 40 contacts the angled part of the packaging bag, and realizes the angle flattening by moving along the X-axis and the Y-axis, and the directions of the X-axis and the Y-axis are respectively consistent with the moving directions of the transverse moving component 31 and the longitudinal moving component 32. The tape winding mechanism 50 is used to provide and guide the tape to the angled position, and by driving the moving mechanism 30 to move, the tape is evenly wound on the angle to complete the angle reinforcement work.

[0041] Specifically, the process of wrapping the corners with tape in the present embodiment is as follows: the material processed in the previous step is transmitted to the designated position through the transmission mechanism 20, and a packaging bag is provided on the material at this time. The packaging bag here is a three-dimensional bag with an overall square shape, and the four corners of the packaging bag are not filled, forming a protruding triangle; next, the corner folding mechanisms 40 on both sides arrange and clamp the main body of the material; then the tape winding mechanism 50 is driven by the longitudinal moving component 32 to scrape it from the middle of the unclamped surface to both sides, forming two triangular unfilled parts at the two corners of the material, and then the tape winding mechanism 50 is driven by the lateral moving component 31 to move horizontally, pushing the unfilled part inward and folding it on the clamping surface, and wrapping the folded part with tape during the movement to complete the corner folding processing.

[0042] In summary, by optimizing the design of the moving mechanism 30, the tape is accurately positioned and wound evenly, maintenance costs are reduced, production efficiency is improved, and overall production costs are reduced.

[0043] Combined with reference Figure 2 and Figure 3 As shown, in a possible implementation manner, the tape winding mechanism 50 includes:

[0044] A fixed plate 51, wherein the fixed plate 51 is connected to the longitudinal moving assembly 32;

[0045] A mounting frame 52, the mounting frame 52 is connected to the fixing plate 51,

[0046] A tape receiving seat 53, wherein the tape receiving seat 53 is connected to the mounting frame 52;

[0047] A plurality of pressing wheels 54, wherein the plurality of pressing wheels 54 are rotatably connected to the mounting frame 52;

[0048] A cutting knife 55 , wherein the cutting knife 55 is connected to the mounting frame 52 .

[0049] It can be understood that the fixed plate 51 serves to connect the longitudinal moving component 32, ensuring that the tape winding mechanism 50 can move with the longitudinal moving component 32. The fixed plate 51 can be an L-shaped plate, which can not only serve as a connection, but also the part facing the material can be used to flatten and fold the packaging bag. The mounting frame 52 is used to carry components such as the tape receiving seat 53, the pressure wheel 54 and the cutting knife 55. It is one of the core components of the entire tape winding mechanism 50. The mounting frame 52 is roughly triangular and fixedly connected to the fixed plate 51. The tape receiving seat 53 is used to place the tape roll to ensure that the tape can be smoothly unfolded and guided to the corner of the packaging bag. The function of the pressure wheel 54 is to press the tape against the corner of the packaging bag to ensure that the tape can fit tightly and help the tape to unfold smoothly. The cutting knife 55 is used to cut off the excess tape after the tape winding is completed to ensure that the length of the tape used each time is appropriate.

[0050] Specifically, first, the tape roll is placed on the tape receiving seat 53, the tape is pulled out from the tape roll, and is guided to the folded corner of the packaging bag by the pressure wheel 54; the pressure wheel 54 presses the tape on the folded corner of the packaging bag to ensure that the tape can fit tightly and help the tape to unfold smoothly; as the longitudinal moving component 32 moves, the tape is wound along the folded corner of the packaging bag until the required number of winding turns is reached; after the tape is wound, the cutting knife 55 cuts off the excess tape to ensure that the length of the tape used each time is appropriate.

[0051] In a possible implementation manner, a cantilever 531 is further provided on the tape receiving seat 53 , one end of the cantilever 531 is connected to the mounting frame 52 , and the other end is rotatably connected to the tape receiving seat 53 .

[0052] Through the rotation function of the cantilever 531, the tape can be smoothly unrolled to prevent the tape from twisting or tangling during the winding process. The rotation of the cantilever 531 allows the tape receiving seat 53 to rotate as needed, which is convenient for recycling the tape and reduces the waste of the tape. The design of the cantilever 531 improves the efficiency of tape winding and reduces the adjustment time of the tape during the winding process.

[0053] In a possible embodiment, a rocker arm 541 is connected to the pressure wheel 54, and the rocker arm 541 is rotatably connected to the mounting frame 52. One end of the rocker arm 541 is connected to a tension spring 542, and the other end is rotatably connected to the pressure wheel 54. The other end of the tension spring 542 is connected to the mounting frame 52.

[0054] It can be understood that one end of the tension spring 542 is connected to the rocker arm 541, and the other end is connected to the mounting frame 52, which is used to maintain the pressure of the pressure wheel 54 to ensure that the tape can be stably pressed on the packaging bag. The function of the tension spring 542 is to maintain the pressure of the pressure wheel 54 on the tape to ensure that the tape can be stably pressed on the packaging bag, and to maintain consistent pressure even when the tape roll is gradually consumed and becomes lighter. The design of the tension spring 542 enables the tape winding mechanism 50 to adapt to tape rolls of different thicknesses, ensuring that the appropriate clamping force can be maintained when the size of the tape roll changes. Through the elastic effect of the tension spring 542, even if the surface of the packaging bag is not completely flat, the tape can be stably pressed, thereby improving the quality of the tape winding.

[0055] Combined with reference Figure 4 and Figure 5 As shown, in a possible embodiment, a push box assembly 21 is provided in the transmission mechanism 20, and the push box assembly 21 includes a driving structure 211, a movable track 212, a lifting structure 213 and a pushing plate 214, the lifting structure 213 is drivingly connected to the driving structure 211 and slidably connected to the movable track 212, and the pushing plate 214 is drivingly connected to the lifting structure 213.

[0056] It can be understood that the driving structure 211 is used to provide power to drive the lifting structure 213 and the push plate 214 to move. The moving track 212 provides guidance for the lifting structure 213 to ensure that the lifting structure 213 can move up and down smoothly. The lifting structure 213 is connected between the driving structure 211 and the push plate 214, and is used to lift and lower the push plate 214 to achieve the lifting and lowering of the material. The push plate 214 is located at the top of the lifting structure 213 and is used to push the material forward. When the material needs to be pushed forward, the driving structure 211 starts to work; the lifting structure 213 moves upward along the moving track 212 under the drive of the driving structure 211, and lifts the pushing plate 214; the pushing plate 214 pushes the material, and after the pushing plate 214 rises to an appropriate height, it lifts the material from the bottom and pushes it forward; the lifting structure 213 descends: when the material is pushed to the specified position, the lifting structure 213 descends under the action of the driving structure 211, and the pushing plate 214 also descends to the initial position, preparing for the next operation.

[0057] Combined with reference Figure 1 As shown, in a possible implementation manner, the packaging bag corner wrapping device further includes a label scanning mechanism 60, and the label scanning mechanism 60 includes:

[0058] A clamping structure 61, which is disposed on the frame 10 and located at the front side of the packaging bag transmission direction, and is used to clamp the material covered with the packaging bag;

[0059] A label printing structure 62, wherein the label is disposed on one side of the clamping structure 61;

[0060] The label applying and code scanning structure 63 is used to apply the label printed by the label printing structure 62 to the material in the packaging bag, and scan the code for identification.

[0061] The clamping structure 61 is arranged on the frame 10 and is located at the front side of the packaging bag transmission direction, and is used to clamp the material covered with the packaging bag. The label printing structure 62 is arranged on one side of the clamping structure 61, and is used to print the label. The label applying and code scanning structure 63 is used to apply the label printed by the label printing structure 62 to the material covered with the packaging bag, and scan the code for identification. Working principle: Material clamping: The clamping structure 61 is actuated when the material reaches the specified position to clamp the material covered with the packaging bag. Label printing: The label printing structure 62 prints the label according to the pre-set information. Label applying: The label applying and code scanning structure 63 applies the printed label to the material.

It can adapt to packaging bags of different sizes and shapes, and meet different packaging needs by adjusting the mechanical structure and parameter settings. When processing packaging bags of different materials, it can adapt to different materials by adjusting the type of label and the application pressure.
