Description

Technical Field

[0001] The utility model relates to the field of graphene heating wire processing, and particularly refers to a material conveying device. Background Art

[0002] Graphene is a two-dimensional material composed of a single layer of carbon atoms, with extremely high thermal conductivity and excellent electrical conductivity. When powered on, the free electrons in graphene move irregularly under the action of an electric current, a phenomenon known as Brownian motion. In this process, the collisions between electrons and the interactions between electrons and carbon atoms generate heat, which is produced by the mutual collisions and frictions of carbon atoms in the resistance layer.

[0003] The electrothermal conversion efficiency of graphene heating tubes is higher than that of commonly used carbon fiber heating tubes at present. Therefore, more and more enterprises are conducting research on related technologies of graphene heating tubes. For example, a graphene film heating tube and its preparation method disclosed in CN117915502A, and a graphene heating film and a heating device including the graphene heating film disclosed in CN208001380U, both of which involve heating wires distributed in a continuous bow shape.

[0004] Due to the fragility of the graphene heating wire itself, in the existing production process, after the graphene heating wire is prepared (with electrodes installed), it is manually threaded into a glass tube / quartz tube, resulting in low production efficiency.

[0005] Therefore, the applicant designed a tube threading guiding mechanism for graphene heating wires in the prior application "2024218819098", which can realize the automatic tube threading of graphene heating wires.

[0006] In order to match the above automatic tube threading mechanism, the applicant also designed a material conveying device, which can realize the orderly and automatic transmission of graphene materials and can be used for material transportation before and after tube threading through this conveying device. Content of the Utility Model

[0007] In order to achieve the above object, the technical solution of the present utility model is as follows:

[0008] A material conveying device, comprising

[0009] A loading unit, above which is used for clamping or carrying materials, and below which a limiting structure is provided;

[0010] A transmission unit, which drives a number of loading units to move in a cyclic and reciprocating manner between the upper layer and the lower layer;

[0011] A positioning unit, which is arranged below the upper-layer loading unit and cooperates with the limiting structure of the upper loading unit.

[0012] Taking the transportation of a graphene material by a carrying unit as an example, when the driving unit drives the carrying unit to operate, when a carrying unit moves to the position where the next carrying unit is located, the positioning unit rises and cooperates with the positioning groove of the carrying unit to complete precise positioning. At this time, the automatic clamping mechanism can grasp or transport the material on the carrying unit.

[0013] Further, when the carrying units are in the upper layer, the carrying units are adjacent and continuously distributed.

[0014] The carrying units in the upper layer are continuously distributed. The carrying units in the lower layer can be separately conveyed, and it is not necessary to be continuously conveyed. It only needs to ensure that the upper layer is continuously distributed in the cycle.

[0015] Further, the driving unit includes a horizontal actuating device and a vertical actuating device. The horizontal actuating device drives the carrying unit to move horizontally, and the vertical actuating device drives the carrying unit from the upper layer to the lower layer, or from the lower layer to the upper layer.

[0016] Further, the carrying unit includes a long and narrow carrier, and both ends of the carrier can move on the slide rails on both sides; the slide rails include fixed slide rails and lifting slide rails. The fixed slide rails are arranged in the upper and lower layers, and the lifting slide rails are arranged at both ends of the fixed slide rails and can be lifted under the drive of the vertical actuating device.

[0017] That is, the carrying unit transports materials in the upper layer. When on the lifting slide rail at one end and the material is taken away, it is transferred from the upper layer to the lower layer, then returns to the lifting slide rail at the other end and rises back to the position where the material is placed to complete a cycle.

[0018] Further, a fixture capable of clamping the end of the graphene heating wire is also arranged on the carrier.

[0019] The above fixture can be provided with a fixed fixture and a movable fixture, and the relative distance between the fixed fixture and the movable fixture can be adjusted to adapt to heating wires of different lengths.

[0020] Further, the limiting structure of the carrying unit is a concave arc structure with its opening facing downwards. The positioning unit includes a protruding arc-shaped component, and the arc-shaped component moves up and down relatively.

[0021] Through the cooperation of the limiting structure of the carrying unit and the positioning unit, the staying position of the carrying unit in the upper layer of the driving unit can be more precise, which is convenient for the automatic clamping mechanism to grasp.

[0022] Further, both the horizontal actuating device and the vertical actuating device are actuated by cylinder drive.

[0023] Further, a cross bar perpendicular to the carrier is arranged at the bottom of the carrier, and the push rod of the horizontal cylinder in the upper layer acts on the cross bar to make the carrier move horizontally.

[0024] Furthermore, limiting rods are provided at both ends of the carrier, and the limiting rods are used for positioning and keeping adjacent carriers at a distance.

[0025] Furthermore, the positioning unit further includes a lifting plate which is pushed to lift by a plurality of air cylinders. A plurality of arc-shaped members are arranged on the lifting plate, and each arc-shaped member cooperates with the limiting structure of the bearing unit.

[0026] After adopting the above scheme, compared with the prior art, the utility model has the following advantages:

[0027] The material transfer between each graphene heating wire processing device is realized, the positioning is accurate, and it is convenient for the respective automatic manipulators to grab. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following further describes the utility model with reference to the drawings and specific embodiments.

[0036] A material conveying device, taking Figure 1Taking the shown angle as an example, its structure mainly includes fixed slide rails 2 arranged front and back. Lifting slide rails 3 capable of performing lifting actions are arranged at the left and right ends of the fixed slide rails 2. A movable carrier 1 is arranged on the fixed slide rails 2 and the lifting slide rails 3. The carrier 1 can hold a graphene heating wire 7 / graphene sheet. The carriers 1 are continuously distributed on the slide rails. When the outermost carrier 1 is pushed from one side, the entire layer of carriers 1 can move. Therefore, taking the upper layer as an example, a horizontal driving cylinder 4 is arranged on the left side. When the push rod of the horizontal driving cylinder 4 extends, it moves from left to right, thereby causing the entire layer of carriers 1 to move. And since the lifting slide rails 3 are arranged at both ends of the fixed slide rails 2, when the carrier 1 on the left side is pushed away, a position for one carrier 1 is vacated. The lifting driving cylinder 5 can transport the carrier 1 on the lower layer to the upper layer, while the carrier 1 at the rightmost end on the lifting slide rail 3 is transported to the lower layer. The movement direction of the carrier 1 on the lower layer is opposite to that of the upper layer.

[0037] Embodiment reference of the carrier 1 Figure 1 、 2 As shown, its base is a long and narrow guide rail. A cross bar 12 and a limiting rod 11 are arranged at the bottom of the guide rail. The limiting rod 11 is located at both ends, and the cross bar 12 is located in the middle. The limiting rod 11 and the cross bar 12 are both perpendicularly distributed to the guide rail. The limiting rod 11 is used to determine the distance between the carriers 1, that is, restricted by the limiting rod 11, so that a certain spacing distance is maintained between the carriers 1; while the cross bar 12 is used to interact with the aforementioned horizontal driving cylinder 4, so that the carrier 1 can move along the slide rail. Clamps 13 are arranged at both ends of the uppermost part of the carrier 1. The clamps 13 are matched with the graphene heating wire 7 / graphene sheet. A support member 15 for accommodating materials is arranged thereon, and a movable clamping plate 14 is arranged above the support member 15 for clamping the heating wire; in order to adapt to the length of the graphene heating wire 7 (the size will change according to different product specifications), one of the clamps 13 can be made movable and the other can be made fixed.

[0038] As Figure 3 shown, a concave arc structure is arranged at the bottom of the limiting rod 11. The concave arc structure is used for positioning the carrier 1. Specifically, a lifting plate 6 is arranged below the corresponding carrier 1. A plurality of protruding arc-shaped components 61 are arranged on the lifting plate 6. When the lifting plate 6 is lifted and lowered under the drive of the cylinder, the arc-shaped components 61 can enter / leave the bottom of the limiting rod 11, thereby realizing the precise positioning of the carrier 1 and ensuring the accuracy of automatic transmission.

At the same time, words such as "upper, lower, left, right, middle" involved in the present invention are only for reference and are not absolutely limited.
