It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , the utility model provides a packaging machine clamp body.

[0025] The utility model provides a kind of packaging machine clamp body, including driving part 15 and rotating shaft 1, one end of the rotating shaft 1 is equipped with first clamping piece 2, the side of the driving part 15 is equipped with second clamping piece 3 close to the first clamping piece 2, first clamping site 201 is equipped on the first clamping piece 2, second clamping site 301 is equipped on the second clamping piece 3, the rotating shaft 1 can be linearly moved between first position and second position along the axial direction, for example, rotating shaft 1 can be slidably connected with other structures along the axial direction of rotating shaft 1, the driving part 15 is used to drive the rotating shaft 1 rotates between first position and second position, the first clamping piece 2 is in contact with the second clamping piece 3 in first position and first clamping site 201 is opposite to second clamping site 301, the first clamping piece 2 is separated from the second clamping piece 3 in second position and first clamping site 201 is staggered with second clamping site 301 to enable packaging bag to be moved to second clamping site 301 along the axial direction of the rotating shaft 1.

[0026] Before packaging bag, rotating shaft 1 moves from first position to second position, first clamping piece 2 is separated from second clamping piece 3, during the movement of first clamping piece 2, first clamping piece 2 rotates to make first clamping site 201 gradually stagger with second clamping site 301, after first clamping piece 2 reaches second position, first clamping site 201 is staggered with second clamping site 301, and first clamping site 201 does not coincide with second clamping site 301 in the axial direction of rotating shaft 1, other packaging bag conveying mechanism can convey packaging bag to second clamping site 301 along the axial direction of rotating shaft 1, in other words, packaging bag can be moved to second clamping site 301 along the axial direction of rotating shaft 1, after packaging bag reaches second clamping site 301, rotating shaft 1 moves from second position to first position, during which, first clamping piece 2 rotates and approaches second clamping piece 3, first clamping piece 1 is pressed on second clamping piece 3 after reaching first position, in other words, packaging bag is clamped between first clamping site 201 and second clamping site 301 to achieve the purpose of clamping packaging bag, of course, when there is no packaging bag, first clamping piece 2 in first position can be directly contacted with second clamping piece 3.

[0027] To make clamping packaging bag more firm, anti-skid structure 4 can be provided on first clamping site 201 and the second clamping site 301, and the anti-skid structure 4 can be a concave-convex plate, a rubber pad or a suction cup, etc.

[0028] The driving part 15 can include gears, rollers or magnets, etc. Taking gears as an example, the rotating shaft 1 can correspond to a spline shaft or have a spline shaft structure, the gears mesh with the spline shaft, and the gears and the spline shaft can be slidably fitted along the axial direction of the rotating shaft 1, so that the rotating shaft 1 can move linearly along the axial direction between the first position and the second position. During the linear movement of the rotating shaft 1 along the axial direction, the gears can rotate and drive the rotating shaft 1 to rotate. Taking rollers as an example, the rollers are in contact with the circumferential surface of the rotating shaft 1, and the rotating shaft 1 can slide along the axial direction relative to the rollers. When the rotating shaft 1 slides, it remains in contact with the rollers, so that the rotating shaft 1 can move linearly along the axial direction between the first position and the second position. When the rollers rotate, they drive the rotating shaft 1 to rotate by relying on friction. Taking magnets as an example, magnets can be arranged at intervals in the circumferential direction of the rotating shaft, and an electromagnetic coil can be arranged near the rotating shaft. The magnets can move along the axial direction of the rotating shaft 1 relative to the electromagnetic coil. After the electromagnetic coil is energized, repulsion or attraction is generated between the electromagnetic coil and the magnets on the rotating shaft 1, thereby driving the rotating shaft 1 to rotate. The principle is similar to that of a rotating motor.

[0029] As a possible embodiment, the driving part 15 can include a sleeve 5 sleeved on the rotating shaft 1, the second clamping piece 3 is fixed on one side of the sleeve 5 close to the first clamping piece 2, the rotating shaft 1 is slidably fitted with the sleeve 5 along the axial direction of the rotating shaft 1, the rotating shaft 1 is provided with a pin column 6, and the sleeve 5 is provided with a spiral groove 7 extending around the axis of the rotating shaft. The pin column 6 is slidably fitted with the spiral groove 7, the first clamping piece 2 is located at the first position when the pin column 6 is located at one end of the spiral groove 7, and the first clamping piece 2 is located at the second position when the pin column 6 is located at the other end of the spiral groove 7. When the rotating shaft 1 moves linearly along the axial direction, the pin column 6 slides along the spiral direction of the spiral groove 7, thereby driving the rotating shaft 1 to rotate.

[0030] The angle between the two ends of the spiral groove 7 along the axial direction of the rotating shaft 1 can be used to set the rotation angle range of the first clamping piece 2, that is, the angle of the first clamping piece 2 between the first position and the second position. For example, to set the rotation angle range to 90 degrees, the angle between one end of the spiral groove 7 and the other end along the circumferential direction of the rotating shaft 1 is 90 degrees. It can also be set to 30 degrees, 45 degrees, 60 degrees or other angles according to the shape of the packaging bag or other requirements.

[0031] In order to reset the rotating shaft 1 and save energy, the packaging machine clamping body further comprises an elastic member 8 arranged between the rotating shaft 1 and the sleeve 5, and the elastic member 8 is used to drive the rotating shaft 1 to move from the second position to the first position. The elastic member can be a spring, the spring can be sleeved on the rotating shaft 1, one end of the spring can abut or be fixed with the sleeve 5, and the other end can abut or be fixed with the rotating shaft. During the movement of the rotating shaft 1 from the first position to the second position, the spring is compressed, and the rotating shaft 1 can move from the second position to the first position by relying on the elastic force generated by the compression of the spring. The process of moving the first clamping piece 2 from the second position to the first position by relying on mechanical driving can be omitted, and other elastic members can also be arranged in the same way as the spring.

[0032] Please refer to Figure 4 and Figure 5 The packaging bag transfer mechanism provided by the utility model comprises the packaging machine clamping body and a supporting member 10, the supporting member 10 is provided with a driving mechanism, a plurality of packaging machine clamping bodies are arranged on the supporting member 10 along the extension direction of the supporting member 10, and the driving mechanism is used to drive the rotating shaft 1 to move from the first position to the second position. Wherein, the plurality of refers to two or more than two.

[0033] For example, the packaging bag clamped by the packaging machine clamping body can be conveyed to a vacuumizing device through an intermediate transfer mechanism. For example, the intermediate transfer mechanism can comprise a parallelogram support and a clamping jaw, the clamping jaw is fixed on one side of the parallelogram support, the clamping jaw is used to receive the packaging bag on the packaging machine clamping body, the parallelogram support is driven to rotate, and the clamping jaw rotates along an arc track with the parallelogram support. Since one side of the parallelogram support provided with the clamping jaw can always keep horizontal, the opening of the packaging bag on the clamping jaw can always keep upward, so that the material in the packaging bag is prevented from spilling, and the packaging bag is conveniently sent into the vacuumizing device.

[0034] The supporting member 10 can be a supporting plate, a supporting rod or a supporting frame and the like commonly used supporting structures; the driving mechanism can be a rotary motor and a cam shaft, the rotary motor drives the cam shaft to rotate, a cam on the cam shaft pushes the other end of the rotating shaft 1, so that the rotating shaft 1 moves in the axial direction. In order to prevent the cam from wearing the rotating shaft 1, a pushing plate 9 can also be arranged at the other end of the rotating shaft 1; the driving mechanism can also be a telescopic device, a supporting member and an inclined sliding block, the inclined sliding block is fixed on the supporting member, the telescopic device drives the supporting member to move in the radial direction of the rotating shaft 1, and the inclined surface of the inclined sliding block is in contact with the other end of the rotating shaft 1. The inclined sliding block pushes the rotating shaft 1 to move in the axial direction during the movement of the supporting member.

[0035] As a possible implementation, each packaging machine clamp body can be configured with an independent driving mechanism, for example, the driving mechanism can include a plurality of telescopic devices 11 corresponding to the packaging machine clamp body, the telescopic devices 11 are used to drive the rotating shaft 1 to move from the first position to the second position, and the telescopic devices 11 can be air cylinders, oil cylinders or electric telescopic rods, etc.

[0036] As a possible implementation, a plurality of packaging machine clamp bodies can also be driven by less telescopic devices 11 than the number of packaging machine clamp bodies, for example, the driving mechanism can include a telescopic device 11 and a driving piece 14 connected to the telescopic device 11, the telescopic device 11 drives a plurality of rotating shafts 1 of the packaging machine clamp bodies to move from the first position to the second position through the driving piece 14, and the driving piece 14 can be a structure such as a plate or a rod extending along the distribution direction of the packaging machine clamp bodies, and the driving piece 14 can be in contact with a plurality of rotating shafts 1 at the same time under the pushing of the telescopic device 11, so that at least one telescopic device 11 can drive a plurality of packaging machine clamp bodies.

[0037] A plurality of clamping stations can be formed between the plurality of packaging machine clamp bodies, that is, one clamping station between each two adjacent packaging machine clamp bodies, and each adjacent packaging machine clamp body can clamp one side of a packaging bag, so as to improve the transfer efficiency. For example, the first clamping position 201 and the second clamping position 301 are two respectively, and the two first clamping positions 201 and the two second clamping positions 301 are respectively arranged symmetrically with respect to the axis of the rotating shaft 1, and the first clamping position 201 and the second clamping position 301 of the adjacent two packaging machine clamp bodies are opposite to each other, and when clamping the packaging bag, the two sides of the packaging bag are respectively located on the two opposite first clamping positions 201 and second clamping positions 301, so that the setting of multiple clamping stations can be realized.

[0038] In order to facilitate the adjustment of the position of the packaging machine clamp body on the support piece 10, a support sliding block 12 can be arranged on the other side of the sleeve 5, and the support piece 10 is provided with a sliding groove 13 extending along the extension direction of the support piece 10, and the support sliding block 12 is in sliding fit with the sliding groove 13, and when adjusting the position of the packaging machine clamp body, the support sliding block 12 can be pushed to slide in the sliding groove 13.
