[038] With reference to the Figures, a fusion welding device of the present invention comprises a fusion welding work motor 200, a mobile fusion welding work assembly and a fixed fusion welding work assembly; the fusion welding work motor is connected to the mobile fusion welding work assembly by means of a transmission mechanism; the fusion welding device has a central connection component 1 which is rotatably connected to a fixed mounting base 100, and the numerical reference 10 is a rotating shaft of the central connection component. The central connection component has a first entry position 11, a second entry position 12 and a locking structure connection position 13. The mounting base 100 is mounted on a base 300 of a portable baler.

[039] The first input position 11 adopts a sector gear and is transmissively connected to a clutch of the output component 201 of the fusion welding work motor 200. The first output component 201 adopts a gear and is mounted on the output shaft of the motor 205. The fusion welding work motor 200 can drive the first input position 11 to produce a rotation in a second direction (embodied as rotation in the counterclockwise direction of the first). Petition 870220090972, dated 04 / 10 / 2022, page 14 / 140 10 / 20 input position 11 in Figure 5) via the first output component 201, and thus drive the central connecting component 1 to rotate in the second direction as a whole, and after rotating to a defined angle, the two disengage, said defined angle corresponding to the rotation angle required for the fusion welding work assembly to move to a fusion welding work location (i.e., moving from the angle in Figure 5 to the angle in Figure 6). Due to the adoption of the sector gear, the clutch timing and rotation angle are controlled by determining the sector angle of the gear, the structure is simple, and the clutch operation is reliable and stable.

[040] The second input position 12, based on the drive of the fusion welding work motor 200, produces rotation in the first direction, to cause the central connection component 1 to produce rotation in the first direction and cause the first input position 11 to be connected to the first output component 201.

[041] The fusion welding device is equipped with a locking structure for the fusion welding working state of the fusion welding working assembly; the locking structure is arranged obliquely; the upper end of the locking structure and the locking structure connection position 13 are articulated by means of the shaft 21; shaft 21 is parallel to shaft 10; the lower end of the locking structure is rotatably connected to the fusion welding working assembly; the fusion welding device is equipped with a limiting structure to limit the maximum rotation angle of the central connection component 1 in the second direction when fusion welding work is performed. At the maximum rotation angle, the sector gear and the output component are disengaged; the limiting structure is composed of the gear 101 in the frame of the portable baler and the stop block 14 in the central connection component 1.

[042] The preferred structure of the locking structure above is that in Petition 870220090972, dated 04 / 10 / 2022, page 15 / 140 11 / 20 that the locking structure is composed of an upper assembly and a lower assembly, the upper assembly is provided with a first connecting component 24, and the connecting component 24 and the pressing and locking outlet connecting component 13 for fusion welding work are articulated by means of a shaft 21; the second connecting component 25 is provided in the lower assembly, and the second connecting component 25 is rotatably connected to the fusion welding work assembly. A compression spring 22 is provided between the upper and lower assemblies. The first connecting component in the upper assembly is provided with a nut 26 and is connected to the length adjustment component 23 by a threaded connection, and the length adjustment component 23 is inserted into the second connecting component 25. The locking structure, the fusion welding work assembly,and the central connecting component 1 are configured so that, when the fusion welding work is in operation (Figure 6), the locking structure is in a locked state, and the first input position 11 and the output component 201 are in a disengaged state, the central connecting component 1 maintains a tendency to rotate in the second rotational direction, and the geometric axis of rotation for the rotational connection between the locking structure and the locking structure connection position 13 is outside the first side of the plane; before the fusion welding work begins (Figure 5), the moving assembly of the fusion welding work is in an elevated state, the locking structure is in an unlocked state, the geometric axis of rotation for the rotational connection between the locking structure and the locking structure connection position is outside the second side of the plane,and the first input position 11 and the first output component 201 are in a connected state; the plane is the plane that passes through the geometric axis of rotation of the central connecting component and the geometric axis of rotation for the rotational connection between the fusion welding workpiece and the, Petition 870220090972, dated 04 / 10 / 2022, page 16 / 140 12 / 20 locking structure, and the first and second sides are divided into the front and rear sides of the plane.

[043] The mobile fusion welding work assembly comprises a mounting frame 31, the mounting frame 31 is rotatably mounted on the mounting base 100 by means of a bearing 32, and the mounting frame 31 is also connected to the central connecting component by means of the fusion welding work state locking structure; specifically, the mounting frame 31 is rotatably connected to the second connecting component 25 by means of the pin shaft 27. Thus, rotation of the central connecting component 1 in the second direction causes the mobile fusion welding work assembly to rotate at the angle for fusion welding work by means of the locking structure and is locked without reverse rotation.

[044] The mobile fusion welding work assembly comprises a top spring 37 for arranging the mounting frame between the mounting frame 31 and the mounting base 100.

[045] The mobile fusion welding work assembly comprises a fusion welding work component 33 and a fusion welding work power input connection component 34, the fusion welding work component 33 and the connection component 34 are articulated, and the fusion welding work power input connection component 34 is connected to one end of the transmission mechanism 202 by means of an eccentric shaft 35; the transmission mechanism 202 may be a belt drive mechanism, the eccentric shaft 35 is connected to the driven wheel 203 of the transmission mechanism, and the flywheel 204 of the transmission mechanism is connected to the output shaft 205 of the fusion welding work motor;The fusion welding workpiece 33 is slidably connected to the guide rail 36 on the mounting frame 31, and a pressure adjustment ball can be provided in the arc groove between its sides, and the workpiece; Petition 870220090972, dated 04 / 10 / 2022, page 17 / 140 13 / 20 fusion welding 33 is slidably connected to the guide rail 36; the geometric articulation axes of the fusion welding work component 33 and the fusion welding work power input connection component 34 are parallel to the geometric rotation axis of the mounting frame 31 and are also parallel to the eccentric axis 35.

[046] The fusion welding work motor 200 and the transmission mechanism 202 are in a one-way transmission connection relationship, when the central connection component 1 is driven by the fusion welding work motor 200 to move in the first direction, the fusion welding work motor 200 and the transmission mechanism 202 are in a drive disengagement connection, and the fusion welding work motor 200 does not drive the transmission mechanism 202. The same can be connected by means of a one-way bearing in the corresponding direction between the flywheel 204 and the output shaft 205 of the fusion welding work motor.

[047] The fusion welding work motor 200 and the second input position 12 are in a one-way transmission connection relationship, but opposite to the one-way transmission connection relationship direction between the fusion welding work motor 200 and the transmission mechanism 202, when the central connection component is driven by the fusion welding work motor 200 through the input connection of the first input position 11 and moves in the second direction, the fusion welding work motor and the second input position are in a drive disengagement connection, and the central connection component is driven to rotate by the motor driving force received by the first input position.

[048] The fusion welding work motor 200 is configured to automatically rotate in a reverse direction after the fusion welding work is completed, which can obtain the automatic reverse rotation signal by setting the fusion welding work time, and cause the central connection component 1 to produce a rotation. Petition 870220090972, dated 04 / 10 / 2022, page 18 / 140 14 / 20 reset in the first direction by connecting to the second input position 12. When the portable baler is started, once the power is turned on, the 200 fusion welding work motor also works in the reverse direction to reset the device.

[049] The second input position 12 also adopts a sector gear with a certain sector angle. The fusion welding work motor 200 can drive the second input position 12 to rotate in the first direction by means of the second output component 206. The second output component 206 also adopts a gear. For unidirectional drive of the second output component 206, it can also be connected to the output shaft 205 of the fusion welding work motor through a unidirectional bearing 207 in a corresponding direction.

[050] Therefore, in the present invention, the first output component 201, the second output component 206, and the flywheel 204 of the transmission mechanism are all mounted on the output shaft of the fusion welding work motor, thus simplifying the automatic control which can achieve a non-reset gripping operation based on the solutions of the present invention and greatly simplifying the structure. The resetting means that when the central connecting component rotates in the first direction, the fusion welding work assembly can be opened to place a packing belt between the fusion welding work assembly and the fixed fusion welding work assembly; after the central connecting component rotates in the first direction, the opening can be performed automatically by means of the return spring 37.

[051] The front end of the first input position sector gear 11 is equipped with an elastic tooth component that engages with the first output component 201 in the first direction, so that it can have extensive adaptability when the central connection component 1 is reset and rotated in the first direction, ensuring that the automatic connection of the overall work of the portable baler is achieved. The component Petition 870220090972, dated 04 / 10 / 2022, page 19 / 140 The 15 / 20 elastic tooth adopts a metal elastic sheet 5 and is connected to the front side 15 of the sector gear in the first direction by means of a connecting structure. The first tooth 16 at the front end of the sector gear body in the first direction is a half-tooth with a notch 17 on the front side. The elastic sheet 5 is located in front of the notch 17, and the notch 17 is used to form the elastic sheet's sash to exert elasticity.

[052] The fixed fusion welding work assembly is a stationary structure at the bottom of the portable baler, and a fixed friction structure 4 is arranged on the upper surface. The fusion welding work component 33 is fitted with the fixed friction structure 4, and causes the joints of the baling belt to be heated and friction-welded.

[053] When operating, in the fusion welding working state, the fusion welding working motor 200 rotates forward for a specified period of time according to the set time, and the packing belt joints are welded. After the time expires, in the absence of manual intervention, the fusion welding working motor 200 receives a reverse rotation signal according to the set time interval.

[054] When the fusion welding work motor 200 begins to rotate in reverse, the entire central connection component 1 rotates in the first direction (clockwise direction in Figure 6) with the engagement of the second output component 206 and the second input position. Thus, the first input position 11 is rotated from the disengaged state with the first output component to the engagement between the two, and continues to rotate to the position shown in Figure 5; however, since the fusion welding work motor 200 and the transmission mechanism 202 are in a one-way transmission connection relationship, the transmission mechanism does not rotate in reverse. After the locking frame connection position 13 rotates in the first direction, the geometric axis of rotation between the inclined locking frame and the locking frame connection position 13 also rotates outwards on the second side of the aforementioned plane. Petition 870220090972, dated 04 / 10 / 2022, page 20 / 140 16 / 20 the locking structure is thus unlocked, and the mounting frame 31 can be rotated and raised for resetting, and the attached packing belt can be removed and, at the same time, the packing belt that needs to be packed and welded is put in place (Figure 5).

[055] After the first input position 11 is subjected to the aforementioned actions, the entire central connection component 1 rotates in the first direction (counterclockwise direction in Figure 5), thus the second input position 12 rotates to the position shown in Figure 5. However, due to the unidirectional transmission connection relationship between the fusion welding work motor 200 and the transmission mechanism 202, although the output component 201 is engaged with the second input position 12, the transmission mechanism does not rotate in the opposite direction.After the locking frame connection position 13 is rotated in the first direction, the geometric axis of rotation between the inclined locking frame and the locking frame connection position 13 also rotates outward on the second side of the aforementioned plane, thus releasing the locking. The mounting frame 31 can then be rotated and raised to a state as shown in Figure 5. The attached packing belt can be removed, and the packing belt that needs to be packed and welded can be put on at the same time.

[056] In the next packaging work cycle, the start switch can be pressed, the packaging belt will be tensioned by the tensioning device; when the packaging belt is tensioned, the current of the tensioning device's drive motor will change to cause the fusion welding work motor 200 to receive signals, and the fusion welding work motor 200 automatically starts to rotate forward, so that the output component 201 is driven to rotate, the first input position 11 is driven to rotate in the second direction, and in this way, the entire central connection component 1 is rotated in the second direction, and the geometric axis of rotation between the structure Petition 870220090972, dated 04 / 10 / 2022, page 21 / 140 17 / 20 of inclined locking and the locking frame connection position 13 also rotates outwards on the first side of the plane to achieve locking; under the state, the tendency of the compression spring 22 keeps the central connection component 1 from rotating in the second rotational direction, so that the stop block 14 is pressed against the gear 101 of the limiting frame, and under the action of the compression spring 22, the mounting frame 31 is pressed down at an angle for fusion welding work and enters the fusion welding work state. At this time, the first input position 11 is moved only enough to disengage from the first output component 201 (Figure 6).At the same time, since the fusion welding work motor 200 and the second input position 12 are in a one-way transmission connection relationship, the second input position 12 only rotates at a corresponding angle with the central connection component 1.

[057] In the fusion welding working state, the fusion welding working motor 200 drives the fusion welding working component 33 to move back and forth under the guidance of the guide rail 36 by means of the transmission mechanism 202, the eccentric shaft 35, and the fusion welding working power input connection component 34 to perform the fusion welding work. At the same time, since the fusion welding working motor 200 and the second input position 12 are in a one-way transmission connection relationship, the second input position 12 is not driven to rotate and does not interfere with the locked state. At the same time, since the sector gear has been disengaged from the output component 201 (Figure 6), and the state is maintained by the locking structure, and for the first input position 11, this will not interfere with the locked state.Therefore, the central connection component 1 remains in normal working condition without interference.

[058] After the fusion welding work is finished, the reverse rotation work of the fusion welding work motor 200 is started. Petition 870220090972, dated 04 / 10 / 2022, page 22 / 140 18 / 20

[059] With reference to Figures 9, 10, 11, and 12, the meanings of the same numerical references in Figures 9-12 are the same as those in Figures 1-8, please refer to the description of the modalities above.

[060] In this embodiment, the clutch connection structure of the first input position 11 and first output component 201 includes the following structures:

[061] The motor output gear 201 is provided with a shaft hole 212, the motor output shaft 205 penetrates the shaft hole 212, and a torsion spring 214 is provided between the motor output shaft 205 and the first output component 201 (hereinafter referred to as the motor output gear); There is a circumferential spacing G between the motor output shaft 205 and the motor output gear 201. The motor output shaft 205 has a first drive position 2051 and drives the sector gear of the first input position 11 to rotate in the second direction. The motor output shaft 205 has a second drive position 2052 and drives the sector gear of the first input position 11 to rotate in the first direction after the sector gear 11 is disconnected from the motor output gear 201 and rotated to a connected state.

[062] The working direction of the torsion spring 214 is that, after the sector gear of the first input position 11 rotates at a certain angle and is disengaged from the motor output gear 201, the motor output gear 201 is driven to continue rotating when the motor output shaft 205 stops rotating, to cause the motor output gear 201 (protrusion 215 in this embodiment) to disengage the connection with the first drive position 2051, and to contact the second drive position 2052.
