[0033] Please refer to Figure 1 and Figure 2 together. Now, a material clamping and conveying module for a packaging machine provided by an embodiment of the present application will be described. The material clamping and conveying module for the packaging machine includes a material bearing platform 100, a support plate 200, a servo sliding table 300, a fixed clamping assembly and a movable clamping assembly. Among them:

[0034] The material receiving platform 100 forms a feeding plane 101; the supporting plate 200 is arranged at an interval from the feeding plane 101; the servo slide table 300 is connected to the supporting plate 200 and is used to drive the supporting plate 200 to reciprocate in directions perpendicular and parallel to the feeding plane 101. Here, the servo slide table 300 can adopt a two-dimensional servo slide table in the prior art. The supporting plate 200 is connected to the output end of the servo slide table 300 to realize driving the supporting plate 200 to move in directions perpendicular and parallel to the feeding plane 101; the fixed clamping assembly includes a first slider 401 and a second slider 402 respectively slidingly connected to the supporting plate 200, and also includes a plurality of pushing feet 403 connected to the first slider 401 at uniform intervals, a plurality of material blocking feet 404 connected to the second slider 402 at uniform intervals, and a screw 405 threadedly connected to at least one pushing foot 403 and at least one material blocking foot 404 respectively. The sliding directions of the first slider 401 and the second slider 402 relative to the supporting plate 200, the arrangement directions of the plurality of pushing feet 403 and the plurality of material blocking feet 404, and the axial direction of the screw 405 are all parallel to the feeding plane 101. The pushing feet 403 and the material blocking feet 404 are alternately distributed, and the thread rotation directions of the pushing feet 403 and the material blocking feet 404 for cooperating with the screw 405 are opposite; the moving clamping assembly is installed on the supporting plate 200 and is used to cooperate with the pushing feet 403 to clamp the target material.

[0035] According to the above structure provided in this embodiment, in the material clamping and conveying module for a packaging machine provided in this embodiment, the moving clamping assembly can cooperate with the pushing feet 403 (usually the outermost pushing foot 403) in the fixed clamping assembly to clamp the target material onto the feeding plane 101 of the material receiving platform 100 and can convey the target material forward for a certain distance along a direction parallel to the feeding plane 101. Since the pushing feet 403 are evenly spaced, when the support plate 200 reciprocates along a direction parallel to the feeding plane 101 under the drive of the servo sliding table 300 and the distance of reciprocating movement is equal to the spacing distance between the pushing feet 403, each subsequent operation of the moving clamping assembly cooperating with the pushing feet 403 to clamp and convey the target material can make the previous target material move forward by the same distance under the action of the pushing feet 403. And a number of blocking feet 404 that are alternately distributed and evenly arranged with the pushing feet 403 in the fixed clamping assembly can play a role similar to that of the moving clamping assembly and enable each target material to be clamped and conveyed. In addition, since the pushing feet 403 and the blocking feet 404 are respectively connected to the first slider 401 and the second slider 402 that have the same sliding direction relative to the support plate 200, and the threads of the pushing feet 403 and the blocking feet 404 for cooperating with the screw 405 are opposite, only by controlling the screw 405 to rotate around its own axis can the distance between the pushing feet 403 and the blocking feet be flexibly adjusted and made to more flexibly adapt to target materials of different specifications and sizes. In this way, the material clamping and conveying module for a packaging machine provided in this embodiment can have a high material conveying efficiency, which is conducive to significantly improving the packaging efficiency of the packaging machine and is far superior to the prior art.

According to the above structure provided in this embodiment, the plurality of pressing plates 406 can effectively prevent the first slider 401 and the second slider 402 from disengaging from the sliding grooves 201, which is beneficial to further improving the material conveying efficiency of the material clamping and conveying module for the packaging machine in this embodiment.

[0039] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the fixed clamping assembly further includes supports 407 movably sleeved at both ends of the screw 405 and connected to the support plate 200 to support the rotation of the screw 405; the supports 407 extend in a direction perpendicular to the sliding grooves 201 and span all the sliding grooves 201. According to the above structure provided in this embodiment, the supports 407 can also achieve the technical effect of preventing the first slider 401 and the second slider 402 from disengaging from the sliding grooves 201 while supporting the screw 405, which is beneficial to further improving the material conveying efficiency of the material clamping and conveying module for the packaging machine in this embodiment.

[0040] In another embodiment of the present application, please refer to Figure 1 and Figure 2, the moving clamping assembly includes a cylinder seat 501 connected to the support plate 200, a cylinder 502 mounted on the cylinder seat 501, and a clamping foot 503 with one end connected to the output shaft of the cylinder 502; the middle position of the clamping foot 503 is hinged to the second slider 402 and can make the end of the clamping foot 503 away from the cylinder 502 approach or move away from a corresponding pusher foot 403 during the telescopic process of the cylinder 502. According to the above structure provided in this embodiment, on the one hand, the cylinder 502 can cooperate with the pusher foot 403 to clamp the target material by driving the clamping foot 503 to rotate relative to the support plate 200; on the other hand, since the clamping foot 503 is hinged on the second slide table, the distance between the clamping foot 503 and the pusher foot 403 can also be adjusted by the screw 405, which is beneficial to making the distance between the clamping foot 503 and the pusher foot 403 more conveniently adapted to the target material and is beneficial to further improving the material conveying efficiency of the material clamping and conveying module for the packaging machine in this embodiment.

[0041] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the material clamping and conveying module further includes a cross plate 601 connected to the clamping foot 503 and the pusher foot 403 and used to increase the contact area between the clamping foot 503 and the pusher foot 403 and the target material.

According to the above structure provided in this embodiment, the guiding surface 441 provided on the material blocking foot 404 can make the target material more conveniently enter the interval between the pusher foot 403 and the material blocking foot 404 and be more stably clamped by the pusher foot 403 and the material blocking foot 404, which is beneficial to further improving the material conveying efficiency and stability of the material clamping and conveying module for the packaging machine in this embodiment.

In this embodiment, when the material clamping foot 503 is reset by the tension spring 602, it is in a state of clamping the material with the corresponding material pushing foot 403. Thus, since the pulling force of the tension spring 602 is stable, the clamping force for clamping the material is also stable, avoiding the problem of clamping force fluctuation caused by air pressure when using a cylinder in a conventional structure. According to the above structure provided in this embodiment, the tension spring 602 capable of automatically resetting the material clamping foot 503 to clamp the material is beneficial to significantly reducing the consumption of compressed air of the cylinder 502, that is, the cylinder 502 only works when opening the material clamping foot 503, which is beneficial to energy conservation.
