[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a specific embodiment, a connecting flange 102 is installed on the clamp cover 101, and a plurality of pairs of positioning holes 1021 are opened on the connecting flange 102.

The author connects the connecting flange 102 to the execution end of the mechanical arm, and the internal electric push rod 103 needs to be connected to the computer that controls the mechanical arm. The above connection method is a prior art and will not be repeated.

[0024] like Figure 4 and Figure 5 It is shown that further, a gap is left between the pair of strip plates 107, the swing rod 106 is movably inserted in the gap, a slide bar 1061 is installed at the end of the swing rod 106, a strip groove 1071 is opened on the strip plate 107, the strip groove 1071 is a through groove, and the slide bar 1061 is slidably set in the strip groove 1071.

During the sliding process of the slide bar 1061, the angle of the rocker arm 106 installed with the slide bar 1061 changes.

[0025] Embodiment 2: The difference between the above embodiment and this embodiment is that: Figure 4 , Figure 5 and Figure 6 As shown, bearings 1042 are clamped on both sides of the rotating shaft 104, and bearing seats 1041 are clamped on the outer wall of the bearings 1042. The bottom of the bearing seats 1041 is welded to the inner wall of the clamp cover 101, and the height of the rotating shaft 104 is higher than the height of the top of the pressing block 108. During the sliding process of the slide bar 1061, the swing rod 106 equipped with the slide bar 1061 rotates with the rotating shaft 104 inside the bearing seat 1041, and the bearings 1042 inside the bearing seat 1041 can reduce the friction during the rotation process. After the rotating shaft 104 rotates, it can drive the mounting plate 105 and the clamping claw 1051 at the end to rotate inward, so as to clamp the package sleeve at the center.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in a specific embodiment, the bottom of the clamping jaw 1051 and the pressing block 108 are both placed outside the clamping cover 101, the inner wall of the clamping jaw 1051 is installed with an anti-skid pad, the bottom of the pressing block 108 is installed with a buffer plate, and the surfaces of the clamping jaw 1051 and the pressing block 108 are both arc-shaped. The top plate 1032 drives the vertical rod 1081 and the pressing block 108 to move downward continuously, so that the pressing block 108 and the packaging sleeve can be closely fitted, thereby improving the stability of the clamping. The anti-skid pad can increase the friction force, thereby improving the stability during the clamping process.

[0027] like Figure 4 and Figure 8 As shown, further, a synchronous plate 2011 is installed on the back of the flip plate 201, a limiting seat 2041 is installed on the synchronous plate 2011, a push rod 204 is movably inserted inside the limiting seat 2041, a soft pad 202 is installed on the blocking plate 2022, the back of the blocking plate 2022 is in contact with the positioning block 2021 installed on the side wall of the clamp cover 101, a positioning shaft 2023 is installed at the rotation center of the blocking plate 2022, and the positioning shaft 2023 and the mounting seat on the synchronous plate 2011 are movably hinged.

[0028] Embodiment 3: The difference between the above embodiment and this embodiment is that: Figure 4 and Figure 8 As shown, the rotation center of the flip plate 201 and the rotation center of the push rod 204 are located on the same straight line, a positioning seat 2012 is rotatably installed on the rotation center of the flip plate 201, the positioning seat 2012 is welded to the side wall of the clamp cover 101, and a torsion spring is clamped between the positioning seat 2012 and the rotation center of the flip plate 201.

[0029] like Figure 8 and Fig. 9 As shown, in a specific embodiment, a positioning rod 2061 is installed on the extrusion block 2052, a positioning sleeve 206 is inserted on the positioning rod 2061, and the positioning sleeve 206 is welded and installed on the inner wall of the installation cavity 1082, a slide plate 2062 is slidably installed inside the positioning sleeve 206, a positioning rod 2061 is installed at the bottom of the slide plate 2062, and a return spring 2063 is sleeved on the positioning rod 2061, one end of the return spring 2063 is clamped at the bottom of the slide plate 2062, and the other end is clamped at the inner wall of the positioning sleeve 206. When the extrusion block 2052 moves upward, the positioning rod 2061 is driven to move inside the positioning sleeve 206, and then the slide plate 2062 slides inside the positioning sleeve 206, thereby stretching the return spring 2063, and the stretched return spring 2063 facilitates the subsequent reset processing of the extrusion block 2052.

[0030] like Figure 6 and Figure 7 As shown, further, an unlocking cavity 3012 is provided at the bottom of the unlocking cover 301, and a baffle 3022 is slidably arranged inside the unlocking cavity 3012, the baffle 3022 and the card block 302 are in contact with each other, and an unlocking spring 3023 is card-connected between the bottom of the baffle 3022 and the inner wall of the unlocking cavity 3012, the compression direction of the unlocking spring 3023 is the same as the movement direction of the baffle 3022, an inclined surface 3021 is provided on one side surface of the card block 302, a card slot 3031 is provided inside the fixed block 303, the card block 302 is inserted in the card slot 3031, and the fixed block 303 is inserted in the card hole 1013 opened on the side wall of the clamp cover 101. Start the electric push rod 103, and the electric push rod 103 drives the top rod 1031 connected to the output end to move downward. After the top rod 1031 moves downward, it can drive the L-shaped rod 3011 of the side wall to move downward, pulling the unlocking cover 301 and the block 302 on the surface to separate from the slot 3031 on the fixed block 303, and then the synchronous plate 2011 and the flip plate 201 are driven to reverse through the torsion spring, and finally the push rod 204 and the side rod 205 on the synchronous plate 2011 are moved to the same straight line, making it convenient for the side rod 205 to push the push rod 204 to move. When resetting in the later stage, the electric push rod 103 retracts to the specified position, and the synchronization plate 2011 is manually flipped over. The fixed block 303 on the synchronization plate 2011 squeezes the inclined surface 3021 of the card block 302. At this time, the card block 302 retracts into the unlocking cover 301 until it moves to the card slot 3031 position. At this time, the card slot 3031 is reset by the unlocking spring 3023. In this way, the synchronization plate can be opened at the specified position, ensuring that the volume of the clamping cover becomes smaller during normal movement, making it more convenient to move.

[0031] The implementation principle of a packaging sleeve clamping device of this embodiment is as follows: When the device needs to be used, the operator connects the connecting flange 102 to the execution end of the robot arm, and the internal electric push rod 103 needs to be connected to the computer that controls the robot arm. The above connection method is existing technology and will not be repeated.

[0032] When the equipment moves to the specified position, the electric push rod 103 is started, and the electric push rod 103 drives the top rod 1031 connected to the output end to move downward. After the top rod 1031 moves downward, it can drive the L-shaped rod 3011 of the side wall to move downward, pulling the unlocking cover 301 and the block 302 on the surface to separate from the slot 3031 on the fixed block 303, and then the synchronous plate 2011 and the flip plate 201 are reversed through the torsion spring, and finally the push rod 204 and the side rod 205 on the synchronous plate 2011 are moved to the same straight line, which is convenient for the side rod 205 to push the push rod 204 to move. When resetting in the later stage, the electric push rod 103 retracts to the specified position, and the synchronization plate 2011 is manually flipped over. The fixed block 303 on the synchronization plate 2011 squeezes the inclined surface 3021 of the card block 302. At this time, the card block 302 retracts into the unlocking cover 301 until it moves to the card slot 3031 position. At this time, the card slot 3031 is reset by the unlocking spring 3023. In this way, the synchronization plate can be opened at the specified position, ensuring that the volume of the clamping cover becomes smaller during normal movement, making it more convenient to move.

[0033] During the downward movement of the top rod 1031 , the top rod 1031 drives the top plate 1032 and the installed strip plate 107 to move downward synchronously, wherein a slide bar 1061 is slidably provided in the strip groove 1071 on the strip plate 107 , and the slide bar 1061 slides in the strip groove 1071 at this time.

[0034] When the slide bar 1061 slides, the rocker arm 106 equipped with the slide bar 1061 rotates inside the bearing seat 1041 with the rotating shaft 104, and the bearing 1042 inside the bearing seat 1041 can reduce the friction during the rotation process. After the rotating shaft 104 rotates, it can drive the mounting plate 105 and the clamping claw 1051 at the end to rotate inward, so that the packaging sleeve at the center position can be clamped, and during the clamping process, the top plate 1032 drives the vertical rod 1081 and the pressure block 108 to move downward continuously, so that the pressure block 108 and the packaging sleeve can be tightly fitted, thereby improving the stability of the clamping.

[0035] During the process of the pressing block 108 and the packaging sleeve being fitted together, the internal extrusion block 2052 is simultaneously subjected to pressure and begins to move upward, and then the swing arm 2051 on the extrusion block 2052 drives the side rods 205 on both sides to start moving to both sides, and the side rods 205 can eventually drive the push rod 204 that has been flipped to the same straight line to move, and at this time the push rod 204 slides in the limit seat 2041, and during the sliding process, the rack 2043 at the end of the push rod 204 drives the gear 2042 to rotate, and the gear 2042 drives the blocking plates 2022 on both sides to rotate through the positioning shaft 2023, and after the blocking plates 2022 rotate, the two ends of the packaging sleeve can be limited, thereby reducing the phenomenon of the packaging sleeve slipping.

[0036] As the extrusion block 2052 moves upward, it drives the positioning rod 2061 to move inside the positioning sleeve 206, and then the slide plate 2062 slides inside the positioning sleeve 206, thereby stretching the return spring 2063. The stretched return spring 2063 facilitates the subsequent resetting of the extrusion block 2052.
