It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0027] Combination Figures 1 to 5 As shown, the clamping mechanism and honeycomb paper stretching machine package provided by the embodiment of the utility model include a driving mechanism 3, two support columns 2, the support columns 2 are installed on the driving mechanism 3, the driving mechanism 3 is used to drive the support columns 2 on both sides to move synchronously in the lateral direction, and the two support columns 2 move synchronously toward each other and fit on the same side of the outer wall of the paper roller, a first clamping mechanism 4, two of which are fixedly assembled on the upper ends of the two support columns 2, a second roller set 6 is installed on the upper surface of the support column 2, and the second roller set 6 cooperates with the first clamping mechanism 4 on the same side to limit the rotation position of the end of the paper roller.

[0028] Thus, the support column is moved by the driving mechanism so that its side wall is against the paper tube, and then the first clamping mechanism cooperates with the second roller group at the upper end of the support column to clamp the paper roll, thereby achieving effective positioning of the paper roll and the paper roll, and then the whole device is stabilized by the second clamping mechanism, thereby improving the efficiency and stability during operation and the quality of the honeycomb paper after stretching.

[0029] In some embodiments, Figure 2 and Figure 5As shown, the driving mechanism 3 includes a rectangular protective shell 31, a motor 32, a driving bevel gear 33, a first screw 34, a first driven bevel gear 35, a second screw 36 and a second driven bevel gear 37. The motor 32 is fixedly connected to the middle of the upper end of the rectangular protective shell 31, and the output end of the motor 32 is rotatably connected to the driving bevel gear 33. The driving bevel gear 33 is rotatably connected to the rectangular protective shell 31 through a bearing. The gear teeth of the driving bevel gear 33 are meshed with the gear teeth of the first driven bevel gear 35 and the second driven bevel gear 37 on both sides of the length direction of the rectangular protective shell 31. The thick end of the first driven bevel gear 35 is fixedly connected to the first screw 34, the thick end of the second driven bevel gear 37 is fixedly connected to the second screw 36, the other end of the first screw 34 is rotatably connected to one end of the inner wall of the rectangular protective shell 31, and the other side of the second screw 36 is rotatably connected to the other end of the inner wall of the rectangular protective shell 31, the upper end of the rectangular protective shell 31 is provided with a groove along the length direction, the lower ends of the two support columns 2 are threadedly connected to the first screw 34 and the second screw 36 respectively through the groove, and the second clamping mechanism 5 is rotatably connected to both sides of the lower surface of the rectangular protective shell 31.

[0030] The inner wall of the support column 2 is coated with a lubricating layer.

[0031] Therefore, before the device starts working, the starting motor 32 drives the active bevel gear 33 to rotate, and then drives the first driven bevel gear 35 and the second driven bevel gear 37 to rotate, and the support column 2 is limited by the groove of the rectangular protective shell 31, and then drives the support column 2 to move, so that the inner walls of the two support columns 2 are against the paper roll. Since the inner wall of the support column 2 is coated with a lubricating layer and is not tightly fitted with the paper roll, it does not affect the normal use of the device.

[0032] The moving speeds of the two support columns 2 are the same, and the moving directions of the two support columns 2 are both toward the motor 32 .

[0033] In some embodiments, Figure 3 and Figure 4 As shown, the first clamping mechanism 4 includes a cylinder 41, a clamping plate 42, and a first roller group 43. There are two groups of first roller groups 43. The cylinder 41 is installed in the middle of the upper surface of the support column 2. The output end of the cylinder 41 is fixedly connected to the clamping plate 42. Two groups of first roller groups 43 are installed at both ends of the lower surface of the clamping plate 42. The upper end of the support column 2 and the positions corresponding to the two groups of first roller groups 43 are respectively provided with a honeycomb paper roll roller fixing groove and an inner lining paper roll roller fixing groove. The inner lining paper roll roller fixing groove is located closer to the paper outlet. The second roller group 6 is installed in the honeycomb paper roll roller fixing groove and the inner lining paper roll roller fixing groove.

[0034] Therefore, after the paper roll is clamped, the cylinder 41 is started to drive the first roller set 43 on the clamping plate 42 to move downward, tightly fitting with the surface of the paper roll placed on the second roller set 6, so as to clamp the paper roll and reduce the wear between the device and the device, thereby increasing the service life of the device.

[0035] The second roller set 6 comprises four rollers, which are installed in pairs in the paper roll fixing groove. The diameters of all rollers in the first roller set 43 and the second roller set 6 are the same.

[0036] In some embodiments, Figure 1 and Figure 3 As shown, there are two second clamping mechanisms 5, which are installed on both sides of the lower surface of the driving mechanism 3. The second clamping mechanism 5 includes a two-way cylinder 51, a slide groove 52, a clamping rod 53 and a suction cup 54. There are two clamping rods 53. The upper ends of the two clamping rods 53 are hinged to one end of the lower surface of the rectangular protective shell 31, and the lower ends of the two clamping rods 53 are hinged to the suction cup 54. The slide groove 52 is opened on the clamping rod 53 along the length direction. The two-way cylinder 51 is installed between the two clamping rods 53, and the two ends of the two-way cylinder 51 are slidably connected to the slide groove 52 on the same side.

[0037] Therefore, after the paper roll and the paper roller are fastened, the two-way cylinder 51 is started to drive the two clamping rods 53 to approach the two-way cylinder 51, and then the suction cup 54 installed at the bottom increases the gripping force of the device, making the device more stable.

[0038] like Figure 1 As shown, a honeycomb paper stretching machine is provided, wherein the honeycomb paper enters the stretching machine 1 after being clamped by a clamping mechanism.

[0039] The following is combined with Figure 1-5 Describe a specific embodiment of the utility model:

[0040] like Figure 1-Figure 5 As shown, it includes a stretching machine 1 driving mechanism 3, which is installed on the stretching machine 1, a support column 2, which is two in number and is installed on the driving mechanism 3. The driving mechanism 3 is used to drive the support columns 2 on both sides to move synchronously in the horizontal direction. The two support columns 2 move synchronously toward each other and fit on the same side of the outer wall of the paper roller. There are two first clamping mechanisms 4, which are respectively fixedly assembled on the upper ends of the two support columns 2. A second roller set 6 is installed on the upper surface of the support column 2. The second roller set 6 cooperates with the first clamping mechanism 4 on the same side to limit the rotational position of the end of the paper roller. The second clamping mechanism 5 is rotatably connected to both sides of the lower surface of the rectangular protective shell 31.

[0041] In actual use, the paper roll is put on the paper roll roller, and the two ends of the paper roll roller are placed on the second roller group 6 in the paper roll roller storage groove on the support column 2. Before the device starts working, the motor 32 is started to drive the active bevel gear 33 to rotate, and then the first driven bevel gear 35 and the second driven bevel gear 37 are rotated, and the support column 2 is limited by the slot of the rectangular protective shell 31, and then the support column 2 is driven to move, so that the inner walls of the two support columns 2 are firmly against the paper roll. After the paper roll is clamped, the cylinder 41 is started to drive the clamping plate 4 The first roller set 43 on 2 moves downward and fits tightly with the surface of the paper roll placed on the second roller set 6, so as to clamp the paper roll and reduce the wear between the device and the paper roll, thereby increasing the service life of the device and achieving effective fixation of the paper roll and the paper roll. After the paper roll and the paper roll are fastened, the two-way cylinder 51 is started to drive the two clamping rods 53 to approach the two-way cylinder 51, and then the suction cup 54 installed at the bottom increases the grip of the device, making the device more stable, thereby improving the efficiency and stability during work and the quality of the honeycomb paper after stretching.
