[0002] In the use of sealing machines, the cutter is an important component, and its quality and performance directly affect the quality and efficiency of sealing. However, in existing sealing machines, when the cutter is worn or needs to be replaced, it often faces the following problems:

[0003] When the existing equipment seals the fertilizer packaging bags, it is necessary to first cut the packaging bags to size. Long-term use of the equipment causes the cutter to wear seriously, affecting the cutting effect. When replacing the cutter, it is inconvenient to disassemble and install the cutter because it is fixed inside the sealing machine body, resulting in high maintenance costs in the later stage. In addition, when cutting packaging bags of different thicknesses, it is inconvenient to adjust the cutting distance between the cutter and the packaging bag, resulting in cutting failure, affecting the bagging and sealing of the fertilizer. Utility Model Content

[0004] The utility model aims to provide a sealing machine with a cutter that is easy to disassemble and assemble. By arranging a mounting mechanism, the utility model solves the problem that when the existing equipment is used to seal fertilizer packaging bags, the cutter is seriously worn out due to long-term use of the equipment, which affects the cutting effect. When the cutter is replaced, it is inconvenient to disassemble and install the cutter because the cutter is fixed inside the sealing machine body, resulting in high maintenance costs in the later stage. In addition, when cutting packaging bags of different thicknesses, it is inconvenient to adjust the cutting distance between the cutter and the packaging bag, resulting in cutting failure, which affects the bagging and sealing of the fertilizer.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model discloses a sealing machine which is convenient for the disassembly and assembly of a cutting knife, comprising a sealing machine body, a vertical plate fixedly connected to the inner wall of the sealing machine body, a slide groove 1 being provided inside the vertical plate, a support plate fixedly connected to the outer wall of the vertical plate, a lifting block slidably connected to the inside of the slide groove 1, a threaded rod being meshed and rotatably connected to the inside of the lifting block, a cross beam fixedly connected to the side of the lifting block away from the vertical plate, a cover plate being inserted into the top of the cross beam, a slider being slidably connected to the inside of the cross beam, a connecting rod being rotatably connected to the inner wall of the slider, a mounting mechanism being arranged inside the slider, a cutting knife being arranged inside the slider, and a fertilizer packaging bag being contact-connected to the inner bottom wall of the sealing machine body.

[0007] Furthermore, the vertical plates are symmetrically distributed with the sealing machine body as the axis, the threaded rod is rotatably connected to the support plate, and the mounting mechanism includes a fixed plate, and the end of the fixed plate is fixedly connected to the inner wall of the slider.

[0008] Furthermore, a rotating cap is rotatably connected inside the fixed plate, an end of the rotating cap away from the fixed plate is fixedly connected to the end of the sliding block, and a screw rod is meshingly rotatably connected inside the rotating cap.

[0009] Furthermore, one end of the screw rod away from the rotating cap is fixedly connected to a pressing plate, an outer wall of the pressing plate is fixedly connected to an inserting rod, and the inserting rod is symmetrically distributed with the pressing plate as the axis.

[0010] Furthermore, a base plate is provided on a side of the pressing plate away from the screw rod, a limiting sleeve rod is fixedly connected to an outer wall of the base plate, and the limiting sleeve rod is slidably connected to the insertion rod.

[0011] Furthermore, a positioning rod is fixedly connected to a side of the base plate close to the pressure plate, the positioning rod is slidably connected to the pressure plate, and a fixing rod is fixedly connected to a side of the base plate away from the positioning rod.

[0012] Furthermore, one end of the fixing rod away from the base plate is fixedly connected to the inner wall of the sliding block, the outer surface of the positioning rod is slidably connected to the cutting knife, and the pressing plate is in contact connection with the cutting knife.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model rotates the connecting rod so that the connecting rod drives the rotating cap to rotate, so that the rotating cap drives the screw rod to move while rotating, so that the screw rod drives the pressure plate to move away from the base plate, and further the cutter sleeved on the outer surface of the positioning rod is released from the pressure plate. After that, the cutter can be taken out from the positioning rod. After replacing the new cutter, the above operation is reversed to complete the fixation of the cutter, avoiding the use of screws used for fixing the cutter in traditional equipment, thereby greatly reducing the time for replacing the cutter and improving the replacement efficiency.

[0015] 2. The utility model uses the matching setting between the insertion rod and the limiting sleeve rod so that when the screw rod drives the pressure plate to move, the pressure plate will not rotate, and the extrusion and fixation of the cutter can be more stable. By rotating the threaded rod, the threaded rod drives the lifting block to slide downward inside the slide groove, so that the slider inside the crossbeam drives the cutter to move down in height, so that the cutter can effectively contact the outer surface of the packaging bag, so that the cutter can effectively cut the packaging bag, which is convenient for subsequent fertilizer bagging and sealing, so that the sealing machine body can meet the needs of cutting packaging bags of different thicknesses.

[0033] A specific application of this embodiment is:

[0034] When the staff needs to use the device and needs to replace the cutter 12, first rotate the connecting rod 10 so that the connecting rod 10 drives the rotating cap 112 to rotate. Because the rotating cap 112 and the fixing plate 111 are rotatably connected, the rotating cap 112 can maintain the relative position unchanged during rotation, so that the rotating cap 112 will drive the screw rod 113 to move while rotating, so that the screw rod 113 drives the pressing plate 114 to move away from the base plate 116, and further makes the cutter 12 sleeved on the outer surface of the positioning rod 119 be released from the pressing plate 114, and then the cutter 12 is taken out from the positioning rod 119. After replacing the new cutter 12, the above operation is reversed to complete the fixing of the cutter 12, avoiding the use of screws used for fixing the cutter 12 in traditional equipment, thereby greatly reducing the time for replacing the cutter 12 and improving the replacement efficiency. The coordinated arrangement between the rods 117 ensures that the screw rod 113 will not cause the pressing plate 114 to rotate when driving the pressing plate 114 to move, and the extrusion and fixation of the cutter 12 can be more stable. When facing a packaging bag with a thinner thickness, the threaded rod 6 is rotated at this time, so that the threaded rod 6 drives the lifting block 5 to slide downward inside the slide groove 3, and further enables the lifting block 5 to drive the crossbeam 7 to move down in height inside the sealing machine body 1, so that the slider 9 inside the crossbeam 7 drives the cutter 12 to move down in height, so that the cutter 12 can effectively contact the outer surface of the packaging bag, so that the cutter 12 can effectively cut the packaging bag, which is convenient for subsequent fertilizer bagging and sealing. Similarly, when facing packaging bags of different thicknesses, the height of the cutter 12 can be adjusted by rotating the threaded rod 6, so that the sealing machine body 1 can meet the needs of cutting packaging bags of different thicknesses.
