AI Technical Summary
Existing support shafts cause sliding friction during the roll material translation, which may damage the roll material surface.
A support shaft including a shaft core and a roller sleeved on the shaft core is designed. The roller can rotate about the shaft core and move horizontally along the shaft core to achieve automatic reset to prevent damage when the cone top clamps the roll material.
Through the rotation and transverse movement of the roller, the roller material is prevented from being damaged on the lifting mechanism, and the surface of the roller material is avoided when the cone top is clamped.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to a supporting shaft used for a lifting mechanism. Background Art
[0002] At present, a lifting and loading mechanism is generally used to lift and load the roll material. The lifting and loading mechanism includes a cross-arranged swing arm and a supporting shaft arranged on the swing arm. Different lifts are achieved by adjusting the angle of the swing arm. The swing arm is supported on both sides of the roll material through the supporting shaft. When the roll material is lifted to a specified height, the cone top at one end of the unwinding mechanism extends out and inserts into one end of the roll material and applies a certain force to push the roll material. Since the current supporting shaft can only rotate, when the roll material moves horizontally, the roll material moves relatively on the surface of the supporting shaft, and sliding friction may damage the surface of the roll material. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a material supporting shaft to solve the technical problems existing in the prior art.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: a material support shaft, including a shaft core and a roller sleeved on the shaft core, one end of the shaft core is provided with a stopper against the end face of one end of the roller, and the other end of the roller is provided with a receiving groove, and a spring is provided in the receiving groove, and the spring is sleeved on the shaft core, and one end of the spring is against the stopper surface in the receiving groove. The principle of the utility model: the material support shaft is installed at the upper end of the swing arm, and two cross-arranged swing arms support and lift the roll material through the material support shaft so that it can reach the height of loading; when loading, the cone top at one end of the unwinding mechanism first extends into one end of the roll material, and the cone top at the other end of the unwinding mechanism then extends into the other end of the roll material, thereby completing the loading of the roll material. During the loading process, the roll material may rotate on the lifting mechanism. Since the roller can rotate around the shaft core, the roll material is prevented from being damaged; since the roller can move laterally along the shaft core and realize automatic reset, the cone top is prevented from damaging the roll material surface during the process of clamping the roll material.
[0005] As an improvement, the roller is provided with a first through hole running through both ends thereof, the shaft core passes through the first through hole, a second through hole is provided at one end of the roller, the diameter of the first through hole is smaller than the diameter of the second through hole, and the stop surface is formed at the transition between the first through hole and the second through hole.
[0006] As an improvement, the other end of the shaft core extends out of the roller to form an extension section, and the length of the extension section is the same as the length of the stop platform.
[0007] As an improvement, the extension section is covered with a telescopic sleeve, and the spring is arranged between the extension section and the telescopic sleeve.
[0008] As an improvement, the telescopic sleeve is a bellows, one end of the bellows is provided with a connecting pipe, and the connecting pipe is inserted into the accommodating groove.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] During the loading process, the web may rotate on the lifting mechanism. Since the roller can rotate around the axis, the web is prevented from being damaged. Since the roller can move laterally along the axis and automatically reset, the surface of the web is prevented from being damaged during the process of the cone top clamping the web.

[0013] Figure 3 This is a cross-sectional view of the support axis. DETAILED DESCRIPTION
[0014] The utility model will be further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 As shown, a lifting mechanism comprises two parallel and equal-height supporting shafts 2, with swing arms 3 provided at both ends of the supporting shafts 2, the swing arms 3 on the same side of the two supporting shafts 2 being arranged crosswise with each other, and the lifting height can be changed by changing the cross angle of the two swing arms 3. When loading, the roll 1 is placed between the two supporting shafts 2, and the two supporting shafts 2 are supported on both sides of the bottom of the roll 1; the roll 1 is lifted to the specified loading height by the swing of the swing arms 3, that is, the center of the roll 1 is aligned with the cone top of the unwinding mechanism.
[0016] like Figure 2 , 3As shown, the support shaft 2 includes an axis core 22 and a roller 23 sleeved on the axis core 22. One end of the axis core 22 is provided with a stopper 21 that abuts against the end surface of one end of the roller 23, and the end of the stopper 21 is fixedly connected to the swing arm 3; the other end of the axis core 22 is connected to the swing arm 3 on the other side. One end of the roller 23 is provided with a receiving groove 26, and a spring 24 is provided in the receiving groove 26. The spring 24 is sleeved on the axis core 22, and one end of the spring 24 abuts against the stopper surface 27 in the receiving groove 26, and the other end of the spring 24 abuts against the swing arm 3. Under the action of the spring 24, the roller 23 is forced to be close to the stopper 21. The roller 23 is provided with a first through hole that runs through both ends thereof, and the axis core 22 passes through the first through hole. One end of the roller 23 is provided with a second through hole, and the diameter of the first through hole is smaller than the diameter of the second through hole. The stopper surface is formed at the transition between the first through hole and the second through hole, and the second through hole forms the receiving groove 26. The other end of the shaft core 22 passes through the accommodating groove 26 and extends out of the roller 23 to form an extended section. The length of the extended section is the same as the length of the stop platform 21, ensuring that the roller 23 is in the middle position of the swing arms 3 at both ends; the extension section is covered with a telescopic sleeve 25, and the spring 24 is arranged between the extension section and the telescopic sleeve 25. The telescopic sleeve 25 can protect the extended spring 24 and the shaft core 22; the telescopic sleeve 25 is a bellows, and a connecting pipe is provided at one end of the bellows. The connecting pipe is inserted into the accommodating groove 26. During the lateral movement of the roller 23, the bellows can be adaptively telescoped.
[0017] The principle of the utility model is as follows: the support shaft 2 is installed at the upper end of the swing arm 3, and the two cross-arranged swing arms 3 jointly support and lift the roll material 1 through the support shaft 2, so that it can reach the height for loading; when loading, the cone top at one end of the unwinding mechanism first extends into one end of the roll material 1, and the cone top at the other end of the unwinding mechanism then extends into the other end of the roll material 1, thereby completing the loading of the roll material 1. During the loading process, the roll material 1 may rotate on the lifting mechanism, and since the roller 23 can rotate around the shaft core 22, the roll material 1 is prevented from being damaged; since the roller 23 can move laterally along the shaft core 22 and realize automatic reset, it is prevented that the cone top clamps the roll material 1 and damages the surface of the roll material 1.
