[0003] The stretching process of the honeycomb paper stretching machine is to clamp the honeycomb paper through a clamping device, and then use the speed difference between the clamped flat section and the clamped three-dimensional section to produce a stretching effect. The honeycomb paper stretching machine often clamps the honeycomb paper by two rollers against each other. This clamping method will cause the problem of error accumulation during the stretching process, that is, since the stretching amount of the honeycomb paper is not a fixed value, the transmission amount of the honeycomb paper in the three-dimensional section is also a non-fixed value, while the transmission amount of the flat section is fixed. When the accumulated error reaches a certain threshold during the transmission process, the problem of insufficient stretching or excessive stretching will occur, resulting in the phenomenon of accumulation or stretching fracture of the stretching section; at the same time, when this clamping method clamps the three-dimensional section, the damage to the three-dimensional structure of the honeycomb paper is also a problem that cannot be ignored.

[0032] Combination Figures 1 to 5 As shown, the clamping device of a honeycomb paper stretching machine provided by the utility model comprises a clamping block 1, a grid plate 2 and a blowing and suction fan 3.
[0033] Combination Figures 1 to 5 As shown, the upper surface of the clamp block 1 is regularly provided with protrusions 11, and the arrangement regularity of the protrusions 11 is the same as the arrangement regularity of the hollow of the honeycomb paper. The clamp blocks 1 are used in pairs in a manner where the faces where the protrusions 11 are located are butt-jointed, the three-dimensional segment of the honeycomb paper is inserted between the two clamp blocks 1, and the protrusions 11 are inserted into the hollow of the honeycomb paper; the clamp block 1 is fixed on the moving component, and the moving component drives the clamp block 1 to move; the grid area width of the mesh plate 2 is greater than the width of the honeycomb paper, and the flat section of the honeycomb paper is laid on the mesh plate 2; the blowing and suction fan 3 is located on the mesh plate 2 The honeycomb paper stretching machine is characterized in that the honeycomb paper is stretched to the bottom and the suction port of the blowing and sucking fan 3 faces the grid plate 2. The clamping device of the honeycomb paper stretching machine clamps the three-dimensional segment of the honeycomb paper by a clamping block with protrusions having the same arrangement rule as the hollow of the honeycomb paper, thereby reducing the damage to the three-dimensional segment of the honeycomb paper during the clamping process. The suction force of the suction port on the blowing and sucking fan makes the flat segment of the honeycomb paper adsorbed on the grid plate, so that the flat segment of the honeycomb paper does not move during the stretching process, and the flat segment of the honeycomb paper automatically moves after the stretching is completed. This clamping method can ensure the integrity of each hollow stretch of the honeycomb paper and avoid the problem of speed error accumulation.
[0034] In some embodiments, in combination Figure 2 , Figure 3 As shown, the clamping device of the honeycomb paper stretching machine also includes a conveyor belt 4, the number of the conveyor belts 4 is 2, and the two conveyor belts 4 are vertically distributed, and the paired clamping blocks 1 are evenly fixed on the outer walls of the two conveyor belts 4. The clamping blocks 1 are driven to move by the conveyor belts 4, so that the movement requirements of closing, translating and opening of the grouped clamping blocks 1 can be achieved, and the control process of the movement is simplified.
[0035] In some embodiments, in combination Figure 2 As shown, the clamping device of the honeycomb paper stretching machine also includes a motor 5, the number of the motors 5 is 2, the driving ends of the two motors 5 are respectively connected to the rotating shafts of the two conveyor belts 4, the driving directions of the two motors 5 are opposite, and the motors 5 are responsible for driving the grouped clamping blocks 1 to move to realize the stretching action of the stretching machine.
[0036] In some embodiments, in combination Figure 1 As shown, the height of the clamping block 1 in the vertical direction is lower than that of the mesh plate 2. The height difference design can prevent the honeycomb paper of the flattened section from leaving the surface of the mesh plate 2 due to the tensile force during the stretching process, thereby affecting the clamping effect of the flattened section.
[0037] In some embodiments, in combination Figure 2 , Figure 3 and Figure 5 As shown, the top edge of the protrusion 11 is chamfered, and the chamfered design can reduce the damage to the three-dimensional honeycomb paper during the closing process of the group of clamping blocks 1, so that the honeycomb paper can enter between the group of clamping blocks 1 more smoothly.
[0038] In some embodiments, in combination Figure 2 , Figure 3 and Figure 5 As shown, the side of the protrusion 11 is provided with a draft angle of 30°. The design of the draft angle of the side of the protrusion 11 can reduce the area of the top surface of the protrusion, reduce the difficulty of the protrusion 11 entering the gap of the honeycomb paper, and increase the fault tolerance rate.
[0039] In some embodiments, in combination Figure 6 As shown, both ends of the mesh plate 2 are provided with limit grooves 21, and the edges of the limit grooves 21 are provided with chamfers. The limit grooves 21 are used to prevent the flat section of honeycomb paper from being offset when moving on the mesh plate 2, thereby affecting the adsorption effect of the flat section of honeycomb paper. The chamfer design can reduce the damage to the honeycomb paper during the working process of the limit grooves 21.
[0040] In some embodiments, in combination Figure 6 As shown, the clamping device of the honeycomb paper stretching machine also includes a steering auxiliary wheel 22, the diameter of the steering auxiliary wheel 22 is equal to the thickness of the grid plate 2, and the steering auxiliary wheel 22 is rotatably assembled in the limit groove 21. The steering auxiliary wheel 22 can avoid stress concentration at the turning point when the honeycomb paper leaves the grid plate 2, thereby reducing the possibility of breakage.
[0041] In some embodiments, in combination Figure 4As shown, the clamping device of the honeycomb paper stretching machine also includes a flattening wheel 23, which is located just above the end of the mesh plate 2 away from the clamping block 1, and the outer surface of the flattening wheel 23 is in contact with the upper surface of the mesh plate 2. The function of the flattening wheel 23 is to smooth the wrinkles on the honeycomb paper when the honeycomb paper enters the upper part of the mesh plate 2.
[0042] In some embodiments, in combination Figure 4 As shown, the width of the suction port of the blowing and sucking fan 3 is greater than the width of the grid area on the grid plate 2. The blowing and sucking fan 3 with sufficient suction port width can ensure that the honeycomb paper laid on the grid plate 2 receives uniform adsorption force, thereby avoiding the incomplete stretching of the honeycomb paper due to uneven force.
[0043] Working process: the flat honeycomb paper is smoothed by the flattening wheel 23 and then moves to the top of the grid plate 2, and is adsorbed on the top of the grid plate 2 under the action of the blowing and suction fan 3; under the action of the tensile force provided by the clamping block 1, the flat honeycomb paper continuously moves toward the clamping block 1, during which the honeycomb paper is stretched from a flat state to a three-dimensional state under the combined action of the adsorption force and the tensile force; the three-dimensional honeycomb paper will be clamped by the group of clamping blocks 1 and dragged forward, and during the clamping process, the protrusion 11 will enter the gap of the three-dimensional honeycomb paper to reduce the damage to the honeycomb paper during the dragging process, and the three-dimensional honeycomb paper before starting is manually positioned and plugged into the middle of the group of clamping blocks 1.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
