DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] See also Figures 1 to 3 The utility model provides a packaging bag sealing machine, including a workbench 100 and a stapler 200 and a top pressure structure 300 installed on the workbench 100. The stapler 200 includes a lower cover assembly 210, a central shaft 220 and an upper cover assembly 230. The upper cover assembly 230 is hinged to the lower cover assembly 210 through the central shaft 220, and the central shaft 220 is fixedly connected to the upper cover assembly 230. The packaging bag sealing machine also includes a blocking structure 400, the bottom end of which is rotatably arranged on the workbench 100 and connected to the central shaft 220. When the central shaft 220 rotates, it can drive the blocking structure 400 to rotate to be in an upright state directly below the top rod of the top pressure structure 300.

[0023] During use, when the stapler needs to be replaced, first flip the upper cover assembly 230. During the flipping process of the upper cover assembly 230, the central shaft 220 is driven to rotate, and then the blocking structure 400 is driven by the central shaft 220 to flip to an upright state and be located directly below the push rod. At this time, the blocking structure 400 is in the best pressure state. Since the blocking structure 400 is always blocking under the push rod, the operator can perform related stapler installation work. During this process, if the push rod is accidentally driven downward, it may be blocked by the blocking structure 400, thereby preventing the push rod from pressing the operator's hand or other components.

[0024] Specifically, the top pressure structure 300 includes a linkage 410, a rotating shaft 420 and a blocking frame 430. The rotating shaft 420 can be rotatably set on the workbench 100, and the blocking frame 430 includes a support rod 431 and a blocking arm 432. One end of the support rod 431 is fixedly connected to the rotating shaft 420 and is vertically arranged with the rotating shaft 420. One end of the blocking arm 432 is fixedly arranged on the support rod 431, and the other end of the blocking arm 432 extends laterally. When the rotating shaft 420 rotates, the blocking arm 432 can rotate with the support rod 431 to the bottom of the top rod. The linkage 410 is connected between the rotating shaft 420 and the central axis 220, and can drive the rotating shaft 420 to rotate through the linkage 410.

[0025] In a specific implementation, two support rods 431 may be provided, and the two support rods 431 are arranged opposite to each other and supported at both ends of the blocking arm 432. The stability of the entire blocking frame 430 may be improved by the two support rods 431.

[0026] In this embodiment, the linkage member 410 includes a driving wheel 411, a driven wheel 412 and a transmission assembly 413. The driving wheel 411 is sleeved and fixed on the central shaft 220. The driven wheel 412 is sleeved and fixed on the rotating shaft 420. The transmission assembly 413 is connected between the driving wheel 411 and the driven wheel 412. When the central shaft 220 rotates, the driving wheel 411 can drive the rotating shaft 420 to rotate through the driven wheel 412.

[0027] When in use, during normal working hours, the support frame is in a state of covering the workbench 100. When the upper cover assembly 230 is turned over, the central shaft 220 is driven to rotate, and then the rotating shaft 420 is driven to rotate through the driving wheel 411, the driven wheel 412 and the transmission assembly 413, and then the support rod 431 is driven to rotate until the support rod 431 is in an upright state and the blocking arm 432 is located directly under the top rod. When the replacement is completed, the upper cover assembly 230 is rotated in the reverse direction, and the support rod 431 can be driven to rotate in the reverse direction until the positions of the support rod 431 and the blocking arm 432 are restored.

[0028] It should be noted that, in a specific implementation, the rotation angle of the support rod 431 can be adjusted by the transmission ratio between the driving wheel 411 and the driven wheel 412. It should be ensured that the support rod 431 rotates from covering the workbench 100 to standing upright on the workbench 100, that is, flipped 90°, at which time the force state is best.

[0029] In addition, the transmission component 413 can adopt a belt transmission structure, a chain transmission structure or a gear transmission structure commonly used in the prior art.

[0030] As a preferred embodiment, the sealing machine further includes a stopper 440. The stopper 440 is located on one side of the support rod 431, and when the support rod 431 rotates to an upright state, the stopper 440 abuts against one side of the support rod 431. The stopper 440 is located on one side of the support rod 431, and when the support rod 431 rotates to an upright state, the stopper 440 abuts against one side of the support rod 431.

[0031] The stopper 440 can block and limit the support rod 431 to ensure that the stopper arm 432 is located directly below the top rod.

[0032] As another preferred embodiment, the sealing machine further comprises an auxiliary stopper 500. The auxiliary stopper 500 can fix and lock the support rod 431 when the support rod 431 is reversed to an upright state.

[0033] Specifically, the auxiliary stopper 500 includes a fixing frame 510 and a latch 520. The fixing frame 510 is fixed on the workbench 100, the latch 520 is slidably arranged on the fixing frame 510, and a socket 433 is provided on the support rod 431. When the support rod 431 is reversed to an upright state, the latch 520 can be inserted into the socket 433.

[0034] In a normal state, the latch 520 is disengaged from the insertion hole 433 . When the support rod 431 is rotated to an upright state, the latch 520 is pushed to be inserted into the insertion hole 433 , thereby achieving the function of fixing the support rod 431 .

[0035] Specific usage of the above-mentioned packaging bag sealing machine:

[0036] When in use, in the normal state, the support rod 431 is in a state of covering the platform. When the staples need to be replaced, the upper cover assembly 230 is first turned over. When the upper cover assembly 230 is turned over, the central shaft 220 is driven to rotate, and then the rotating shaft 420 is driven to rotate through the driving wheel 411, the driven wheel 412 and the transmission assembly 413, and then the support rod 431 is driven to rotate until the support rod 431 is in an upright state. The blocking arm 432 is located directly below the push rod, and the operator can perform related work of installing the staples. During this process, if the push rod is accidentally driven down, it may be blocked by the blocking structure 400, thereby preventing the push rod from pressing the operator's hand or pressing other parts. When the staple replacement is completed, the upper cover assembly 230 is rotated in the reverse direction, and the support rod 431 can be driven to rotate in the reverse direction until the positions of the support rod 431 and the blocking arm 432 are restored.

[0037] The use of this sealing machine can prevent the ejector rod from accidentally starting and injuring people when replacing the staples, thereby greatly improving the safety during the operation.
