[0001] The utility model provides a material roll rotating shaft spline structure, which relates to the technical field of spline structures. Background Art

[0002] The spline shaft is a kind of mechanical transmission. It has the same function as the flat key, semicircular key and oblique key, and transmits mechanical torque. There is a longitudinal keyway on the surface of the shaft, and the rotating part on the shaft also has a corresponding keyway, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft.

[0003] When steaming food such as buns in a steamer, a piece of steamer paper is placed under the food to prevent the bottom of the food from sticking to the steamer. The steamer paper can prevent the appearance and skin of the buns from being damaged, so the demand for steamer paper in daily life is very large. When producing steamer paper, the steamer paper needs to be rolled up. When rolling the material, the paper tube needs to be put on the motor shaft, and the motor shaft drives the paper tube to rotate and roll the steamer paper. However, the existing rolling shaft cannot adjust the spacing of the paper tubes. If the spacing of the paper tubes is too large, the paper tubes are easy to slide horizontally on the shaft. If the spacing is too small, the paper tubes cannot be completely inserted.

[0004] Therefore, it is necessary to provide a material roll shaft spline structure that can adjust the size of the paper roll placement interval. Utility Model Content

[0005] In order to overcome the disadvantages of the existing material roll shaft that cannot adjust the spacing of paper rolls, which easily causes the paper rolls to slide or cannot be placed, the utility model provides a material roll shaft spline structure that can adjust the size of the paper roll placement interval.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a material roll shaft spline structure, including a spline screw, a second ring and a sliding assembly, the second ring is used to be installed on a driving device, a spline screw is passed through the middle of the second ring, the spline screw is connected to the driving device, a sliding assembly is arranged between the spline screw and the second ring, and also includes a fixed plate, a guide sleeve, a sliding rod and a limit plate, a fixed plate is fixedly connected to the spline screw, a plurality of sliding rods are fixedly connected to the fixed plate, a guide sleeve is slidably sleeved on the sliding rod, and a limit plate is commonly fixedly connected to the plurality of guide sleeves.

[0007] In one embodiment, the sliding assembly includes a guide cylinder slidably arranged on the spline screw, a limit groove is provided on the guide cylinder, a first clamping bead is rollingly arranged in the limit groove, a plurality of linear guide grooves for linear sliding of the first clamping bead are provided on the spline screw, a threaded guide groove for rotational rolling of the first clamping bead is provided on the spline screw, a first ring is fixedly connected to the guide cylinder, the first ring is rotatably connected to the second ring, and a plurality of second clamping beads are rollingly arranged between the first ring and the second ring.

[0008] In one embodiment, a plurality of first mounting holes are formed on the second ring.

[0009] In one of the embodiments, it also includes a connecting plate fixedly connected to the limiting plate, the mounting plate is mounted on the device base, and the connecting plate is rotatably connected to the mounting plate.

[0010] In one embodiment, rubber pads are installed on the sides of the limiting plate and the fixing plate that are close to each other.

[0011] In one of the embodiments, a dust ring is installed on the side of the guide cylinder.

[0012] Compared with the prior art, the spline structure provided in the embodiment of the utility model has the following advantages: 1. The spline screw drives the fixed plate to slide along the translation so that the sliding rod is separated from the guide sleeve. After the paper tube is jointly sleeved on the outside of each guide sleeve and the sliding rod, the sliding rod is inserted into the guide sleeve sleeve, and the paper tube is clamped by the fixed plate and the limit plate to achieve the effect of adjusting the size of the paper tube placement interval.

[0013] 2. The mounting plate can be fixed on the device through the second mounting hole.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] Embodiment 1: A material roll shaft spline structure, see Figure 1-Figure 3 As shown, it includes a spline screw 1, a second ring 6 and a sliding assembly. The second ring 6 is used to be installed on the driving device. The second ring 6 is circumferentially provided with a plurality of first mounting holes 10 to facilitate the installation of the second ring 6 on the driving device. A spline screw 1 is passed through the middle of the second ring 6, and the spline screw 1 is connected to the driving device. A sliding assembly is arranged between the spline screw 1 and the second ring 6, and also includes a fixed plate 7, a guide sleeve 8, a sliding rod 801 and a limit plate 9. The spline screw 1 is fixedly connected with a fixed plate 7 by welding. The fixed plate 7 is circumferentially fixedly connected with a plurality of sliding rods 801 by welding. A guide sleeve 8 is slidably sleeved on the sliding rod 801, and the plurality of guide sleeves 8 are fixedly connected with a limit plate 9 by welding.

[0021] See also Figure 2 As shown, the sliding assembly includes a guide cylinder 2 slidably arranged on the spline screw 1, a limit groove 103 is provided on the guide cylinder 2, a first clamping bead 3 is rollingly arranged in the limit groove 103, a plurality of linear guide grooves 101 are circumferentially provided on the spline screw 1 for the linear sliding of the first clamping bead 3, a threaded guide groove 102 is provided on the spline screw 1 for driving its own rotation, a first ring 4 is fixedly connected to the guide cylinder 2 by welding, the first ring 4 is rotatably connected to the second ring 6, and a plurality of second clamping beads 5 for reducing friction are rollingly arranged between the first ring 4 and the second ring 6.

[0022] When it is necessary to roll up the steamer paper, the ball bearings first roll in the threaded guide groove 102 to drive the spline screw 1 to drive the fixed plate 7 to slide in translation. At this time, the first clamping bead 3 rolls along the linear guide groove 101 to make the sliding rod 801 slide out to the outside of the guide sleeve 8 in translation, so that the guide sleeve 8 is separated from the sliding rod 801, and then the paper tube is jointly sleeved on the outside of each guide sleeve 8 and the sliding rod 801, and the spline screw 1 drives the fixed plate 7 to slide in the opposite direction, and the sliding rod 801 is inserted into the guide sleeve 8, and the paper tube is clamped by the fixed plate 7 and the limiting plate 9. Then, the steamer paper is wound around the paper tube and driven to rotate by the spline screw 1. At this time, due to the joint restriction of the linear guide groove 101 and the limiting groove 103 on the first clamping bead 3, the spline screw 1 drives the guide tube 2 and the first ring 4 to rotate on the inner ring of the second ring 6, and the second clamping bead 5 rolls between the first ring 4 and the second ring 6.

[0023] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes a connecting plate 11 fixedly connected to the side of the limiting plate 9 away from the guide sleeve 8 by welding, and a mounting plate 13 is installed on the device base, and the connecting plate 11 is rotatably connected to the mounting plate 13.

[0024] The mounting plate 13 can be fixed on the device through the second mounting hole 12. When the spline screw 1 drives the fixing plate 7 to rotate, the sliding rod 801 drives the limit plate 9 to rotate through the connection with the guide sleeve 8, and the limit plate 9 rotates on the mounting plate 13 through the connecting plate 11.

[0025] See also Figure 1 and Figure 3 As shown, a rubber pad 14 is installed on the side where the limiting plate 9 and the fixing plate 7 are close to each other by bonding; and a dust ring 15 is installed on the side of the guide cylinder 2 by welding.

[0026] The rubber pad 14 can increase the friction between the paper tube and the fixed plate 7 and the fixed plate 7 to prevent the paper tube from idling and being unable to roll up the steamer paper; when the guide tube 2 slides along the spline screw 1, the dust ring 15 can scrape off the dust on the spline screw 1 and reduce the friction between the spline screw 1 and the guide tube 2.

[0027] 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.
