The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please refer to Figures 1 to 6This utility model provides an angle-adjustable horizontal sealing mechanism for use in packaging machines. It includes a mounting frame 1, a horizontal sealing mechanism 2, a sliding seat 3, a slider seat 4, and a screw lifting mechanism 5. The horizontal sealing mechanism 2 is mounted on the mounting frame 1. The slider seat 4 is slidably mounted on the sliding seat 3. The screw lifting mechanism 5 includes a handwheel 51, an adjusting screw 52, ​​and a nut 53. The handwheel 51 drives the adjusting screw 52 to rotate, and the nut 53 is threadedly connected to the adjusting screw 52. One side of the mounting frame 1 is rotatably connected to the slider seat 4, and the other side is rotatably connected to the nut 53.

[0026] In this embodiment of the invention, the handwheel 51 of the screw lifting mechanism 5 drives the adjusting screw 52 to rotate, causing the nut 53 to move on the adjusting screw 52. Since one side of the mounting frame 1 is rotatably connected to the slider seat 4 and the other side is rotatably connected to the nut 53, the angle of the mounting frame 1 changes accordingly when the nut 53 rises or falls. The horizontal sealing mechanism 2 for sealing the packaging bag 10 is set on the mounting frame 1, thereby achieving the effect of changing the sealing angle of the horizontal sealing mechanism 2 by operating the handwheel 51. The operation of the handwheel 51 is simple and convenient, requiring no complicated tools or professional skills to adjust the sealing angle, thus reducing the labor intensity of the operator.

[0027] The working process of this embodiment is as follows:

[0028] When the angle of the horizontal sealing mechanism 2 needs to be adjusted, the operator stands next to the packaging machine and locates the handwheel 51 of the screw lifting mechanism 5. The operator turns the handwheel 51, which drives the adjusting screw 52 to rotate. Since the nut 53 and the adjusting screw 52 are threadedly connected, according to the principle of thread transmission, the nut 53 will move along the axial direction of the adjusting screw 52. When the nut 53 moves, because one side of the mounting frame 1 is rotatably connected to the nut 53 and the other side is rotatably connected to the slider seat 4, and the slider seat 4 is slidably mounted on the sliding seat 3, the movement of the nut 53 will cause one side of the mounting frame 1 to rise or fall, and the other side of the mounting frame 1 and the slider seat 4 to slide along the length of the sliding seat 3, thereby realizing the flipping of the mounting frame 1. The flipping of the mounting frame 1 drives the horizontal sealing mechanism 2 mounted on it to rotate, realizing the adjustment of the angle of the horizontal sealing mechanism 2 to meet different packaging needs. After the angle adjustment is completed, the horizontal sealing mechanism 2 performs a horizontal sealing operation on the packaging bag 10 at its new angle position. The packaging bag 10 is sealed horizontally by means of heating, pressurization and other methods, thus completing the horizontal sealing process in the packaging process.

[0029] Preferably, the sliding seat 3 includes a pair of parallel linear optical axes 31, with support blocks 32 at both ends of each linear optical axis 31; a sliding block 33 is provided on the linear optical axis 31, and the slider seat 4 is connected to the sliding block 33. In this embodiment, when it is necessary to adjust the angle of the horizontal sealing mechanism 2, the screw lifting mechanism 5 drives the mounting frame 1 to rotate, and the mounting frame 1 drives the slider seat 4 to move. Since the slider seat 4 is connected to the sliding block 33, the sliding block 33 is driven by the slider seat 4 and slides along the length direction of the linear optical axis 31. The linear optical axis 31 provides precise guidance for the sliding block 33, ensuring that the sliding block 33 can only move in the length direction of the linear optical axis 31, thereby ensuring that the slider seat 4 and the connected mounting frame 1 and horizontal sealing mechanism 2 can move smoothly in a predetermined direction, realizing accurate adjustment of the angle of the horizontal sealing mechanism 2.

[0030] Preferably, the mounting frame 1 has a first connecting member 6 and a second connecting member 7 on both sides; the first connecting member 6 includes a first rotating shaft 61 and a first flip plate 62, the two ends of the first rotating shaft 61 are respectively provided with rotatable first support arms 63, and the other end of the first support arm 63 is connected to the mounting frame 1; the first rotating shaft 61 is provided with a first groove, and the first flip plate 62 is fixed to the first groove by bolts; the other end of the first flip plate 62 is connected to the slider seat 4; the second connecting member 7 includes a second rotating shaft 71 and a second flip plate 72, the two ends of the second rotating shaft 71 are respectively provided with rotatable second support arms 73, and the other end of the second support arm 73 is connected to the mounting frame 1; the second rotating shaft 71 is provided with a second groove, and the second flip plate 72 is fixed to the second groove by bolts; the other end of the second flip plate 72 is connected to the nut 53.

[0031] In this embodiment, when the angle of the horizontal sealing mechanism 2 needs to be adjusted, the operator prepares to operate the handwheel 51. At this time, the mounting frame 1 is connected to the slider seat 4 and the nut 53 respectively through the first connecting member 6 and the second connecting member 7, and is in the initial angle position. The operator rotates the handwheel 51, which drives the adjusting screw 52 to rotate, causing the nut 53 to move axially on the adjusting screw 52. When the nut 53 moves, it drives the mounting frame 1 to move through the second connecting member 7. Specifically, the nut 53 drives the second flap 72 connected to it. Since the second flap 72 is fixed to the second groove on the second rotating shaft 71 by bolts, and the second support arms 73 at both ends of the second rotating shaft 71 are rotatably connected to the mounting frame 1, the movement of the second flap 72 will cause the second rotating shaft 71 to rotate, and then drive one end of the mounting frame 1 to rotate around the connection point between the second rotating shaft 71 and the mounting frame 1 through the second support arms 73. When one end of the mounting frame 1 rotates under the action of the second connecting member 7, the other end is connected to the slider seat 4 through the first connecting member 6. The first flap 62 is connected to the slider seat 4 and fixed to the first groove on the first rotating shaft 61 by bolts. The first support arms 63 at both ends of the first rotating shaft 61 are rotatably connected to the mounting frame 1. When the mounting frame 1 rotates, it will drive the first support arms 63 to rotate, thereby causing the first rotating shaft 61 to rotate. The first flap 62 moves with the rotation of the first rotating shaft 61. Since the first flap 62 is connected to the slider seat 4, the slider seat 4 will slide on the linear optical axis 31 of the sliding seat 3 to adapt to the rotation of the mounting frame 1, ensuring that the mounting frame 1 can rotate smoothly around a certain fulcrum, thereby realizing the adjustment of the angle of the horizontal sealing mechanism 2. When the horizontal sealing mechanism 2 is adjusted to a suitable angle, the handwheel 51 is stopped from being turned. At this time, the nut 53 is fixed in position on the adjusting screw 52. The mounting frame 1 and the horizontal sealing mechanism 2 are fixed in a new angle position by the first connecting piece 6 and the second connecting piece 7, so as to carry out the horizontal sealing operation during the packaging process.

[0032] Preferably, the horizontal sealing mechanism 2 includes a mounting base 21, a sliding frame 22, and a connecting rod assembly 23; the mounting base 21 includes a crossbeam 211 and two parallel side plates 212, which are connected by the crossbeam 211; the bottom of the side plate 212 is fixedly connected to the mounting frame 1, and the outer surface of the side plate 212 is provided with a plurality of linear bearings 213, which are slidably connected to the linear bearings 213; the sliding frame 22 is a rectangular frame structure, with a front horizontal sealing roller 24 at its front end; a connecting plate 25 is slidably provided on the sliding frame 22, and a rear horizontal sealing roller 26 is provided on the connecting plate 25; the connecting rod assembly 23 includes a drive unit 231 and a transmission shaft 23. 32. Drive arm 233 and two swing arms 234; the drive unit 231 is mounted on the mounting frame 1 and rotatably connected to the drive arm 233; the transmission shaft 232 is rotatably mounted between two side plates 212; the drive arm 233 and the two swing arms 234 are respectively fixedly connected to the transmission shaft 232, and the two swing arms 234 are respectively located on both sides of the drive arm 233; one end of the swing arm 234 is provided with a rotatable first connecting rod 235, and the other end is provided with a rotatable second connecting rod 236; the other end of the first connecting rod 235 is rotatably connected to the connecting plate 25, and the other end of the second connecting rod 236 is rotatably connected to the rear end of the sliding frame 22.

[0033] In this embodiment, the bottom of the side plate 212 is fixed to the mounting frame 1, and the sliding frame 22 is slidably connected to the linear bearing 213 on the side plate 212, allowing the sliding frame 22 to slide relative to the mounting frame 1. When the packaging machine needs to perform a horizontal sealing operation, the drive unit 231 starts working. The drive unit 231 is mounted on the mounting frame 1 and is rotatably connected to the drive arm 233. The drive unit 231 outputs power to drive the drive arm 233 to perform a circular motion around the transmission shaft 232. Since the drive arm 233 is fixedly connected to the transmission shaft 232, the rotation of the drive arm 233 causes the transmission shaft 232 to rotate between the two side plates 212. The two swing arms 234 are located on both sides of the drive arm 233 and are fixedly connected to the transmission shaft 232, so the rotation of the transmission shaft 232 causes the two swing arms 234 to rotate synchronously, and at the same time, the first connecting rod 235 and the second connecting rod 236 on the swing arms 234 also move accordingly. The first connecting rod 235 drives the connecting plate 25 to slide on the sliding frame 22, and the second connecting rod 236 drives the sliding frame 22 to slide back and forth along the linear bearing 213 on the side plate 212. This movement causes a change in the distance between the front horizontal sealing roller 24 and the rear horizontal sealing roller 26, thereby achieving the clamping and releasing action of the packaging bag 10. During the movement of the sliding frame 22 and the connecting plate 25, the front horizontal sealing roller 24 and the rear horizontal sealing roller 26 clamp the packaging bag 10 and perform a horizontal sealing operation on the packaging bag 10 through heating, pressurization, etc. After the horizontal sealing is completed, the drive unit 231 drives the swing arm 234 to reverse, driving all components back to the initial position, ready for the next horizontal sealing operation.

[0034] By adopting a linkage transmission structure, the transmission is stable and efficient, while also making the entire horizontal sealing mechanism 2 more compact and facilitating angle adjustment.

[0035] Preferably, the drive unit 231 includes a first cylinder 231a and a cylinder seat 231b. The cylinder seat 231b is connected to the mounting bracket 1. The cylinder body of the first cylinder 231a is rotatably connected to the cylinder seat 231b, and the piston rod is rotatably connected to the drive arm 233. In this embodiment, the first cylinder 231a drives the drive arm 233 through the extension and retraction of the piston rod, providing a relatively stable power output. Furthermore, this transmission structure is compact, occupies little space, and can be rationally arranged within a limited space, without causing spatial interference to other components of the horizontal sealing mechanism 2, facilitating angle adjustment.

In this embodiment, the heat emitted by the front heating element 241 and the rear heating element 261 is transferred to the surface of the packaging bag 10, causing the packaging bag 10 to soften. The front horizontal sealing roller 24 and the rear horizontal sealing roller 26 apply pressure to the packaging bag 10, squeezing the softened packaging bag 10 together to achieve a lateral seal of the packaging bag 10. When the sealing is completed, the second cylinder 263 on the connecting plate 25 is activated. The piston rod of the second cylinder 263 extends forward, pushing the cutter 262 connected to it forward, and the cutter 262 inserts into the preset cutting groove on the front horizontal sealing roller 24. The cutting blade 262 works in conjunction with the cutting groove to cut the packaging bag 10, and the sealing and cutting operations of the packaging bag 10 are completed in one horizontal sealing operation.

[0037] Preferably, a sensor bracket 8 is provided on the side plate 212, and a photoelectric sensor 9 is provided on the sensor bracket 8. The detection end of the photoelectric sensor 9 is positioned facing the sliding frame 22. In this embodiment, the photoelectric sensor 9 is positioned facing the sliding frame 22, enabling precise detection of the position of the sliding frame 22. When the sliding frame 22 slides on the linear bearing 213, the photoelectric sensor 9 can monitor its movement in real time, accurately determine whether the sliding frame 22 has reached the designated position, provide a precise position signal for the action of the horizontal sealing mechanism 2, ensure that the horizontal sealing operation is performed in the correct position, thereby improving the accuracy and consistency of packaging.

[0038] Preferably, the screw lifting mechanism 5 further includes a support bearing seat 54 and a mounting plate 55.

In this embodiment, the fixed connection between the support bearing seat 54 and the mounting plate 55 and the packaging machine enhances the structural stability between the entire screw lifting mechanism 5 and the packaging machine, preventing the sealing quality from being affected by the mechanism's shaking or displacement. The support bearing, located at the bottom of the adjusting screw 52 and rotatably connected to the screw, can effectively bear the axial and radial loads of the screw, reducing friction and wear during screw rotation.

[0039] Preferably, the mounting plate 55 is equipped with a digital position display, which is threadedly connected to the adjusting screw 52. By setting up a digital position display and connecting it to the adjusting screw 52, ​​the amount of rotation of the adjusting screw 52 can be read intuitively, improving the control accuracy of the handwheel 51.

[0040] Preferably, the device further includes a tilt alarm device, which comprises a tilt sensor and an alarm. The tilt sensor is mounted on the mounting frame 1 and electrically connected to the alarm. In this embodiment, the tilt sensor is mounted on the mounting frame 1 and can monitor the tilt angle change of the mounting frame 1 in real time. The tilt sensor is electrically connected to the alarm. Once the tilt angle of the mounting frame 1 is detected to exceed a preset safety range, the tilt sensor will immediately transmit a signal to the alarm, which will then sound an alarm to alert the operator.
