[0029] As shown in the attaFigure 1 - Attached Figure 4 As shown, the present utility model provides a pushing / pulling device for conveying materials, which includes a material bearing platform 1, a linear driving mechanism 2, and a pushing / pulling component 3. The pushing / pulling component 3 is a pushing component, a pulling component, or a pushing / pulling component that can both push and pull materials;

[0030] A through groove 14 is provided on the material bearing platform 1 along the pushing / pulling direction of the material. The linear driving mechanism 2 is used to drive the pushing / pulling block 32 of the pushing / pulling component 3 to move on the material bearing platform 1 to push / pull the material. Among them, one end of the material bearing platform 1 along the pushing / pulling direction of the material is the material outlet / inlet end 17. When the pushing / pulling component 3 is used as a pushing component to push the material to move, the material outlet / inlet end 17 is the material discharging end. When the pushing / pulling component 3 is used as a pulling component to push the material to move, the material outlet / inlet end 17 is the material feeding end.

[0031] The linear driving mechanism 2 is arranged below the material bearing platform 1 parallel to the direction of the through groove 14, that is, the moving direction of the output end of the linear driving mechanism 2 is parallel to the length direction of the through groove 14. Among them, the linear driving mechanism 2 can adopt driving mechanisms such as air cylinders, hydraulic cylinders, or electric cylinders. Preferably, the linear driving mechanism 2 is a linear module. The linear module has characteristics such as large load-bearing capacity and precise movement. At the same time, the body of the linear module can be directly arranged below the material bearing platform 1 parallel to the material bearing platform 1 without occupying space. And the linear driving mechanism 2 is arranged below the material bearing platform 1, which will not increase the lateral length dimension of the material bearing platform 1 at all, keeping the structure compact;

[0032] The pushing / pulling material assembly 3 includes a connecting plate 31 and a pushing / pulling block 32. The pushing / pulling block 32 can be a pushing block, a pulling block, or a pushing / pulling block that can both push and pull materials. Specifically, it can be adaptively selected according to the function of this pushing / pulling material device. When the pushing / pulling block 32 is a pushing block, it only needs to adopt a block structure, that is, it is used to abut against the material and push the material to move. When the pushing / pulling block 32 is a pulling block, a connecting structure for detachably connecting with the material is provided on the pulling block. Then, after connecting the material, the material is pulled to move. The connecting structure can be a manually actuated mechanical drive connecting structure. One end of the connecting plate 31 is fixedly connected to the output end of the linear drive mechanism 2, and the other end is located above the material carrying platform 1 and fixedly supports the pushing / pulling block 32. That is, the purpose of the linear drive mechanism 2 is to drive the pushing / pulling material assembly 3 to move above the material carrying platform 1, and then perform a pushing / pulling action on the material carried above the material carrying platform 1. Moreover, the connecting plate 31 can slide in the through groove 14 and can enter or leave the through groove 14 from one end of the through groove 14. Thus, on the basis that the linear drive mechanism 2 is arranged below the material carrying platform 1, it can still drive the pushing / pulling block 32 to push / pull the material on the upper surface of the material carrying platform 1. At the same time, the connecting plate 31 can drive the pushing / pulling block 32 away from the upper surface of the material carrying platform 1, thereby increasing the carrying space of the material carrying platform 1 when there is no need for pushing / pulling.

[0033] The material carrying platform 1 includes a bracket 11 and a graphite plate 12 arranged on the upper surface of the bracket 11. The bracket 11 is used to fixedly support the graphite plate 12, and the graphite plate 12 is used to carry materials. Graphite has self-lubricating properties, with a low friction coefficient, which can reduce the resistance of pushing / pulling materials and at the same time reduce the wear on the materials. Preferably, the materials are contained in graphite crucibles. Sliding friction between the graphite crucibles and the graphite plate 12 can further reduce the friction coefficient between the two.

[0034] Since a through groove 14 is provided on the graphite plate 12, the graphite plate 12 may be composed of two interconnected plate bodies. When the graphite plate 12 bears heavy objects, the levelness of all the graphite plates 12 needs to be consistent to evenly carry the materials. Therefore, the material carrying platform 1 further includes a level adjustment mechanism 13. The graphite plate 12 is arranged on the bracket 11 through the level adjustment mechanism 13, and thus the levelness of the graphite plate 12 can be adjusted to ensure stable and reliable movement of the materials on the graphite plate 12.

[0035] The push / pull material device provided by the present utility model has a compact structure. The linear drive mechanism 2 located below the material loading platform 1 can drive the push / pull block 32 above the material loading platform 1 to push and pull the materials above the material loading platform 1, thereby realizing the conveying of materials. The setting of the through groove 14 can not only provide a sliding space for the connecting plate 31, but also reduce the material used on the surface of the material loading platform 1 without affecting the material loading area. At the same time, when there is no need to push or pull the materials, the push / pull block 32 can be separated from the material loading platform 1, increasing the loading area of the material loading platform 1. And when the upper surface of the material loading platform 1 is arranged with high-cost graphite plates 12, the material cost and the overall weight of the push / pull material device can be reduced. The design of the horizontal adjustment mechanism 13 can make up for the possible unevenness of the graphite plates 12 caused by the setting of the through groove 14 and improve the loading effect of the graphite plates 12.

[0036] In one embodiment, several groups of horizontal adjustment mechanisms 13 are provided on the support 11; several through holes 111 are provided on the support 11. The horizontal adjustment mechanism 13 includes a screw 131, a nut 132 and a support plate 133. The screw 131 is slidably arranged in the through hole 111, and both ends of the screw 131 extend out of both ends of the through hole 111. The nut 132 is screwed on the screw 131 and is located at the upper end of the through hole 111. The upper end of the screw 131 is connected to the support plate 133. In this embodiment, by adjusting the position of the nut 132 on the screw 131, the relative positions of the screw 131 and the support plate 133 relative to the upper end of the support 11 are adjusted. By adjusting multiple groups of horizontal adjustment mechanisms 13, it is ensured that multiple groups of support plates 133 are in the same horizontal position, and then the graphite plates 12 are fixed on multiple support plates 133 to ensure the levelness of the graphite plates 12.

[0037] In a preferred embodiment, the nut 132 is fixedly arranged on the support 11 and is coaxially arranged with the through hole 111; a rotary matching structure is arranged at the lower end of the screw 131. The rotary matching structure can be a square head arranged at the lower end of the screw 131 for easy connection with a rotary wrench, or a screw head, which is also convenient for connection with a rotary wrench. In this embodiment, only by directly rotating the screw 131, the relative height of the screw 131 on the support 11 can be adjusted, simplifying the adjustment difficulty.

[0038] In one embodiment, the support plate 133 and the graphite plate 12 are fixedly connected by bolts to improve the position stability of the graphite plate 12. Preferably, a large washer is pressed between the bolt and the graphite plate 12 to prevent the graphite plate 12 from being cracked by the bolt.

[0039] In one embodiment, a vertical baffle 134 is provided on the support plate 133 located at at least one end of the through slot 14, and the vertical baffle 134 limits the end wall of the graphite plate 12. Specifically, when the push / pull material device is a push material device, that is, when the push / pull material assembly 3 is a push material assembly, a vertical baffle 134 is provided on the support plate 133 located at the material pushing end of the through slot 14. During the material pushing process, the vertical baffle 134 limits the position of the graphite plate 12, and when the graphite plate 12 and the support plate 133 are fixedly connected by graphite bolts, it can also avoid shearing force generated by the graphite bolts when the material friction drives the graphite plate 12 to move, and prevent the graphite bolts from being subjected to radial force to fracture the graphite plate 12. The service life of the graphite plate 12 is improved. When the push / pull material device is a pulling material device, that is, when the push / pull material assembly 3 is a pulling material assembly, a vertical baffle 134 is provided on the support plate 133 at one end of the pulling limit position of the material pulling direction of the through groove 14. During the material pulling process, the vertical baffle 134 limits the position of the graphite plate 12, and when the graphite plate 12 and the support plate 133 are fixedly connected by graphite bolts, it can also avoid shearing force between the graphite bolts and the graphite plate 12 when the material friction drives the graphite plate 12 to move, and prevent the graphite bolts from being subjected to radial force to fracture the graphite plate 12. Improve the service life of the graphite plate 12. Preferably, the support plates 133 at both ends are provided with vertical baffles 134 to improve the stability of the position fixation of the graphite plate 12.

[0040] In one of the embodiments, the side of the through slot 14 that is away from the push-out end or the pull-in end of the material carrying platform 1 is a through slot that penetrates the material carrying platform 1, and the connecting plate 31 can enter or leave the through slot 14 from this side. In this embodiment, the linear drive mechanism 2 can drive the push / pull material assembly 3 to completely withdraw from the surface of the material carrying platform 1, thereby ensuring the bearing area of ​​the material carrying platform 1, and at the same time, the connecting plate 31 can enter the through slot 14 to realize movement on the material carrying platform 1.

[0041] In one embodiment, the through groove 14 is a through groove that passes through both ends of the material carrying platform 1. In this embodiment, the graphite plate 12 is fixed by at least two independent plates, and the interval between the two graphite plates 12 constitutes the through groove 14. Of course, the graphite plate 12 can also be formed by splicing more than two plates to reduce costs.

[0042] In one embodiment, a material inlet / outlet end 15 is provided on one side of the material carrying platform 1 perpendicular to the pushing / pulling direction of the material. When the material pushing / pulling device is a material pushing device, the material inlet / outlet end 15 is used as a material feeding end. When the material pushing / pulling device is a material pulling device, the material inlet / outlet end 15 is used as a material discharging end, that is, it is convenient for the material to enter or leave the material carrying platform 1;

[0043] A guide bar 16 is provided on the side of the material carrying platform 1 opposite to the material inlet / outlet end 15. The guide bar 16 is arranged parallel to the through groove 14. When the push / pull device is a pushing device, the guide bar 16 can limit and position the material when the material enters the material carrying platform 1 from the material inlet / outlet end 15, so as to align the push / pull component 3 with the material. When the push / pull component 3 drives the material to move along the direction of the through groove 14, it can be used as a guiding structure.

[0044] In one embodiment, the guide bar 16 is made of graphite material, thereby reducing the friction coefficient between the guide bar 16 and the material. The guide bar 16 is fixedly connected to the material carrying platform 1 through graphite bolts, which facilitates the disassembly and assembly of the guide bar 16.

[0045] As mentioned above, this is only this embodiment and does not impose any limitations on the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, can make many possible changes, modifications or equivalents to equivalent embodiments by using the technical content disclosed above.
