The fixed seal blade 200 is positioned at one side of the work support 100 in the first direction a, and the movable seal blade 300 is positioned at the other side of the work support 100 in the first direction a. The driving mechanism 400 is connected to the movable sealing blade 300, and the driving mechanism 400 is configured to drive the movable sealing blade 300 to move along the first direction a, so that the movable sealing blade 300 and the fixed sealing blade 200 cooperate to encapsulate the workpiece 600. It will also be appreciated that the wrapping machine 10 includes a work support 100, a fixed seal cutter 200, a movable seal cutter 300, and a drive mechanism 400. The workpiece holder 100 is used to hold a workpiece 600 to be encapsulated. The fixed seal blade 200 and the movable seal blade 300 are disposed opposite to each other in the first direction a. The driving mechanism 400 is connected to the movable seal cutter 300, and the driving mechanism 400 is configured to drive the movable seal cutter 300 to move along the first direction a, so that the movable seal cutter 300 and the fixed seal cutter 200 cooperate to encapsulate the workpiece 600. The workpiece support 100 can fix the workpiece 600 to be packaged, and prevent the workpiece 600 to be packaged from deviating in the packaging process and affecting the sealing effect. This packaging machine 10's fixed seal sword 200 is fixed, and activity seal sword 300 is close to fixed seal sword 200 under actuating mechanism 400's effect to realize sealing sword 200 cooperation with fixed and encapsulate work piece 600, compare in two simultaneous actions of sealing the sword, the displacement tolerance of designing like this can be littleer, is favorable to two accurate cooperations of sealing the sword ground, promotes the encapsulation quality, makes work piece 600's sealed effect better.

In some embodiments, the packaging machine 10 comprises a first base 210 and a second base 421, the first base 210 and the second base 421 being respectively located on both sides of the workpiece support 100 in the first direction a. Optionally, the first base 210 and the second base 421 are both fixed on the ground, the fixed seal blade 200 is fixed on the first base 210, the movable seal blade 300 is slidably connected to the second base 421 along the first direction a, the driving mechanism 400 is mounted on the second base 421, and an output end of the driving mechanism 400 is connected to the movable seal blade 300 to drive the movable seal blade 300 to move relative to the second base 421.

In some embodiments, the drive mechanism 400 includes a primary drive unit 410 and a secondary drive unit 420, the primary drive unit 410 connecting the moveable seal 300 and the secondary drive unit 420. The primary driving unit 410 is used for driving the movable sealing knife 300 to move along the first direction a, and the secondary driving unit 420 is used for driving the primary driving unit 410 to move along the first direction a. By providing two-stage drive, the stroke of the movable seal cutter 300 is conveniently adjusted. Optionally, the secondary driving unit 420 includes a motor 422, a lead screw 423 and a mounting seat 424, wherein the motor 422 is mounted on the second base 421, one end of the lead screw 423 is connected to an output end of the motor 422, the other end of the lead screw 423 is suspended, the mounting seat 424 is in threaded connection with the lead screw 423, the mounting seat 424 is movably connected to the second base 421 along the first direction a, and the primary driving unit 410 is connected to the mounting seat 424. In some embodiments, the second base 421 has a first slide rail 4211, and the mounting seat 424 is slidably engaged with the first slide rail 4211. When the motor 422 rotates, the motor 422 drives the lead screw 423 to rotate, and since the lead screw 423 is in threaded connection with the mounting seat 424, and the mounting seat 424 can only move along the first direction a and cannot rotate, the mounting seat 424 can move along the first direction a under the action of the lead screw 423. Whether the mount 424 moves forward or back and forth (closer to the stationary knife 200 or further from the stationary knife 200) is determined by the direction of rotation of the motor 422. For example, when the motor 422 rotates forward, the mounting seat 424 is moved forward (closer to the stationary seal blade 200). When the motor 422 rotates reversely, the mounting seat 424 is driven to move reversely (away from the fixed seal cutter 200). While the motor 422 drives the mounting seat 424 to move along the first direction a, the mounting seat 424 also drives the primary driving unit 410 connected thereto to move along the first direction a, and finally drives the movable sealing knife 300 to move along the first direction a.

In some embodiments, the primary driving unit 410 includes a driving portion 412 and a connecting seat 411, wherein the driving portion 412 is mounted on the mounting seat 424, the connecting seat 411 is connected to an output end of the driving portion 412, the connecting seat 411 is movably connected to the second base 421 along the first direction a, and optionally, the connecting seat 411 is slidably engaged with the first sliding rail 4211. The driving portion 412 is used for driving the connecting seat 411 to move relative to the second base 421, and the movable sealing knife 300 is connected to the connecting seat 411. When the driving portion 412 is operated, the connecting seat 411 is driven to move along the first direction a, and further the movable sealing knife 300 is driven to move along the first direction a.

In general, when the movable seal cutter 300 needs to be close to the fixed seal cutter 200, the motor 422 rotates forward to drive the mounting seat 424 to move forward, and the driving portion 412 and the connecting seat 411 are driven to move forward while the mounting seat 424 moves forward, so as to drive the movable seal cutter 300 to move forward. After the mounting seat 424 moves forward to a proper position (the mounting seat 424 reaches the maximum stroke on the screw 423), the driving portion 412 moves to drive the connecting seat 411 to move forward again, and further drive the movable sealing knife 300 to move forward, so that the movable sealing knife 300 and the fixed sealing knife 200 are matched to package the workpiece 600.

In some embodiments, the drive portion 412 is a pneumatic cylinder. The driving portion 412 can perform both the flexible connection function and the driving function, that is, the driving portion 412 can not only drive the movable sealing knife 300 to move, but also can be used as a flexible connection element after the output end of the driving portion 412 extends in place. Here, "flexibly connected" means that the movable seal 300 is allowed to move in the first direction a when subjected to a large pressure. In other words, "flexibly connected" means that the movable sealing blade 300 is allowed to move along the first direction a when the pressure applied to the movable sealing blade 300 reaches a threshold value. Because both the thickness of the seal cutter and the stroke of the driving mechanism 400 have errors, if the movable seal cutter 300 is rigidly connected to the driving mechanism 400 (when the movable seal cutter 300 is subjected to a large pressure, the movable seal cutter 300 cannot move relative to the driving mechanism 400, and only the fixed seal cutter 200 can be continuously extruded under the action of the driving mechanism 400), the seal cutter may be damaged due to an excessive pressure between the fixed seal cutter 200 and the movable seal cutter 300 during the packaging process. Therefore, the air cylinder is selected as the driving part 412, and the air cylinder can play a role of flexible connection, so that when a large pressure exists between the fixed seal cutter 200 and the movable seal cutter 300, the movable seal cutter 300 can move relative to the mounting seat 424, the pressure is relieved, and the seal cutter is prevented from being damaged. The effect that can play the flexonics of cylinder is because pressure has between activity seal sword 300 and the fixed seal sword 200, and the effect of power is mutual, the output of cylinder can receive the reaction force of equidimension, when this reaction force is enough big, can compress the gas in the cylinder, make the output withdrawal of cylinder, and the output withdrawal back of cylinder, just reduced the pressure between activity seal sword 300 and the fixed seal sword 200, the regulation of self-adaptation has been realized promptly, the pressure between activity seal sword 300 and the fixed seal sword 200 has been avoided too big. Of course, the driving unit 412 may be a cylinder. The working principle of the air cylinder is the same as that of the air cylinder.

In some embodiments, the driving portion 412 is provided in plural, and the plural driving portions 412 are arranged at intervals along the second direction B, and the second direction B is an extending direction of the movable sealing knife. By providing a plurality of driving portions 412, the stability of the force transmission is increased. For example, referring to fig. 1, 2 and 3, two driving portions 412 are provided. Of course, two or more driving units 412 may be provided.

In some embodiments, the wrapping machine 10 includes a flexible connector 500, the flexible connector 500 flexibly connected between the drive mechanism 400 and the movable sealing blade 300. Specifically, the flexible connector 500 is flexibly connected between the connection seat 411 and the movable sealing blade 300. Through setting up flexible connection spare 500, with flexible connection spare 500 flexonics between actuating mechanism 400 and activity seal sword 300 for when having great pressure between fixed seal sword 200 and the activity seal sword 300, the activity seal sword 300 can take place relative movement with actuating mechanism 400, alleviates pressure, has avoided damaging and has sealed the sword.

In some embodiments, the movable seal blade 300 is rotatably connected to the driving mechanism 400, and the rotation axis of the movable seal blade 300 is arranged along a third direction C, and the first direction a, the second direction B and the third direction C are perpendicular to each other. By rotationally connecting the movable seal cutter 300 to the driving mechanism 400, on one hand, force transmission is facilitated, and the movement stability of the movable seal cutter 300 is increased. On the other hand, when the pressure on one side of the movable seal blade 300 and the fixed seal blade 200 increases due to the thickness of the seal blade and the stroke of the driving mechanism 400, the movable seal blade 300 can rotate adaptively to reduce the pressure, so as to avoid damaging the movable seal blade 300 and/or the fixed seal blade 200. Meanwhile, the movable sealing knife 300 can rotate in a self-adaptive mode, so that the movable sealing knife can be attached to the fixed sealing knife 200 better, the workpiece 600 can be packaged better, and the sealing effect on the workpiece 600 is improved.

In other embodiments, the movable seal 300 is connected to the drive mechanism 400 only by the flexible linkage 500. Specifically, the movable seal 300 is connected to the connecting seat 411 of the driving mechanism 400 only by the flexible connector 500.

In the embodiment where the movable sealing blade 300 is rotatably connected to the driving mechanism 400, the sealing machine 10 comprises two flexible connecting members 500, the two flexible connecting members 500 being located on both sides of the axis of rotation in the second direction B. The two flexible connecting pieces 500 are arranged on the second direction B and located on two sides of the rotation axis, so that self-adaptive adjustment can be performed when pressure between the movable sealing cutter 300 and the fixed sealing cutter 200 is large, and the stability of the movable sealing cutter 300 can be improved.

In some embodiments, the flexible connector 500 is a pneumatic cylinder. The air cylinder is used only as the flexible connecting member 500 and does not have a driving function, that is, the air cylinder used as the flexible connecting member 500 is not used for driving the movable sealing cutter 300 to move. In other embodiments, the flexible connector 500 is a ram. In still other embodiments, the flexible connector 500 is a spring.

Referring to fig. 4 and 5, in some embodiments, the work piece holder 100 includes a clamping mechanism 120 and an adjustment mechanism 110, the clamping mechanism 120 being coupled to the adjustment mechanism 110. The clamping mechanism 120 is used for clamping the workpiece 600 to be packaged, and the adjusting mechanism 110 is used for adjusting the position of the clamping mechanism 120 in the first direction a, so that the clamping mechanism 120 is close to or far away from the fixed seal cutter 200. The clamping mechanism 120 is driven to move in the first direction a by setting the adjusting mechanism 110, and the positions of the clamping mechanism 120 and the fixed seal cutter 200 are adjusted, so as to fix and encapsulate the workpiece 600. For example, when the workpiece 600 needs to be fixed or removed, the adjusting mechanism 110 drives the clamping mechanism 120 away from the fixed seal cutter 200, and the distance between the clamping mechanism 120 and the fixed seal cutter 200 is increased, so as to open the clamping mechanism 120. When the sealing operation is required, the adjusting mechanism 110 drives the clamping mechanism 120 to approach the fixed seal cutter 200, and the distance between the fixed seal cutter 200 and the workpiece 600 is reduced, so that the fixed seal cutter 200 and the movable seal cutter 300 are matched to realize the sealing.

Alternatively, the adjustment base includes a bottom plate 111, a power source 112, and a movable plate 113, wherein the bottom plate 111 may be fixed on the ground, the power source 112 is mounted on the bottom plate 111, and the movable plate 113 is movably connected to the bottom plate 111 along the first direction a. Specifically, a second sliding rail 1111 is disposed on a side of the bottom plate 111 close to the movable plate 113, the second sliding rail 1111 extends along the first direction a, and the movable plate 113 is slidably engaged with the second sliding rail 1111. The clamping mechanism 120 is connected to a side of the movable plate 113 away from the bottom plate 111. When the power source 112 is activated, the movable plate 113 is driven to move along the first direction a relative to the bottom plate 111, so as to drive the clamping mechanism 120 on the movable plate 113 to move closer to or away from the fixed seal blade 200. Power source 112 may be a linear air cylinder, a linear electric cylinder, a linear oil cylinder, or the like.

In some embodiments, a buffer 1112 is further connected to the bottom plate 111, and the buffer 1112 is configured to abut against the movable plate 113 to limit a moving range of the movable plate 113 and prevent the movable plate 113 from moving excessively.

In some embodiments, gripper mechanism 120 includes a drive 124, a transmission 123, a first gripper 121, and a second gripper 122. The driving member 124 is connected to the first clamping member 121, and the first clamping member 121 is connected to the second clamping member 122 through the transmission mechanism 123. The transmission mechanism 123 is used for driving the second clamping member 122 to move reversely when the driving member 124 drives the first clamping member 121 to move along the first direction a. The first clamping member 121 is used for clamping the workpiece 600 in cooperation with the second clamping member 122. By providing the transmission mechanism 123, a linkage between the first clamping member 121 and the second clamping member 122 is realized, and when the driving member 124 drives the first clamping member 121 to move, the second clamping member 122 moves towards the direction opposite to the moving direction of the first clamping member 121, so as to realize the mutual approaching or mutual departing of the first clamping member 121 and the second clamping member 122, so as to fix or release the workpiece 600. For example, when the driving member 124 drives the first clamping member 121 to move forward, the second clamping member 122 moves in reverse under the action of the transmission mechanism 123, and when the driving member 124 drives the first clamping member 121 to move in reverse, the second clamping member 122 moves forward under the action of the transmission mechanism 123.

Alternatively, the first clamping member 121 is movably connected with the movable plate 113 along the first direction a, and the second clamping member 122 is movably connected with the movable plate 113 along the first direction a. Specifically, a third slide rail 1131 is disposed on a side of the movable plate 113 away from the bottom plate 111, the third slide rail 1131 extends along the first direction a, and both the first clamping member 121 and the second clamping member 122 are slidably engaged with the third slide rail 1131.

Referring to fig. 6, the transmission mechanism 123 includes a first link 1231 and a second link 1232, and the first link 1231 and the second link 1232 are crossed and rotatably connected.
