The utility model has the advantages that: the utility model provides a feeding roller has changed the structure of center pin completely, leads to the axle with original integral type and changes into the installation axle that passes through threaded connection including middle screw rod and both ends, owing to be threaded connection, so the whole adjustable length of center pin can be suitable for the barrel of installing different length, has improved the center pin utilization ratio. The clamp spring for clamping the barrel is arranged on the mounting shafts at two ends, so that the relative position of the mounting shaft and the screw can be adjusted to adapt to the barrel even if the length of the barrel has a machining error, the mounting is flexible and convenient, unnecessary waste is avoided, and the production cost is greatly saved.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic diagram of the disassembled structure of fig. 1.

In the figure, 11 screws, 12 installation shafts, 121 clamp spring grooves, 122 locking holes, 2 clamp springs, 31 base pipes, 311 belt driving areas, 312 transmission rubber rings, 313 stainless steel sleeves, 32 end covers, 321 bearings, 4 locking nuts and 5 locking screws.

Detailed Description

Referring to fig. 1 and 2, the feeding roller includes a central shaft and a barrel, the central shaft includes a middle screw rod 11 and an installation shaft 12 respectively connected with two ends of the screw rod 11 through threads, a clamp spring groove 121 is formed in the middle of the installation shaft 12, a clamp spring 2 is arranged in the clamp spring groove 121, the barrel includes a middle base pipe 31 and end covers 32 respectively connected with two ends of the base pipe 31, one side of the base pipe 31 is a belt driving area 311, the outer surface of the other side is coated with a transmission rubber ring 312, the clamp spring 2 is tightly clamped outside the two end covers 32, bearings 321 are fixed in the end covers 32, inner rings of the bearings 321 are tightly fixed on the installation shaft 12, and the installation shaft 12 is further provided with radial locking holes 122 and is locked with the screw rod 11 inside and the installation shaft 12 through locking screws.

The cylinder is clamped in the clamp springs 2 at two ends, the cylinder is clamped by adjusting the length of the thread screwing of the mounting shaft 12 and the screw rod 11, the end cover 32 is tightly connected with the base pipe 31, the outer ring of the bearing 321 is tightly connected with the inner ring of the end cover 32, and the inner ring of the bearing 321 is tightly connected with the outer ring of the mounting shaft 12, so that the cylinder rotates relative to the bearing 321 when in use, and the central shaft and the mounting shaft 12 do not rotate. To ensure that the mounting shaft 12 does not rotate relative to the central axis due to external forces, locking screws are installed in the radial locking holes 122.

And a locking nut 4 is also arranged on the screw rod in the bearing 321 at one side.

In the installation process of the feeding roller, the screw rod 11 can be connected with the installation shaft 12 at one end in a threaded manner, the clamp spring 2 is installed, the installation shaft 12 is locked from the inner side through the locking nut 4 on the screw rod 11, the installation shaft 12 at the other end is installed after the barrel is sleeved, and the locking screw is installed in the radial locking hole 122.

The axial inner screw hole at the center of the mounting shaft 12 is full thread, and a locking screw 5 is further arranged from the outer end of the mounting shaft 12 along the axial direction.

This is another specific way of locking the screw 11 and the mounting shaft 12, and the assembly and disassembly are more convenient.

The pipe diameter of the belt driving area 311 on one side of the base pipe 31 is reduced, a stainless steel sleeve 313 is fixedly clamped, and the outer diameter of the stainless steel sleeve 313 is consistent with that of the base pipe 31.

Because the belt driving area 311 is exposed for a long time, in order to avoid oxidation and rust in the use process, an electroplating mode is adopted, and the whole base pipe 31 must be electroplated due to process limitation during electroplating, so that resources are wasted, the environment is not protected, and the electroplated layer is easy to fall off due to slight collision in use, so that the attractiveness is influenced. The utility model discloses abandon to electroplate, replace with fixing the nonrust steel sleeve 313 of parent tube 31, not only can not rust and be afraid of and bump cladding material, the friction through the belt is more showing light pleasing to the eye moreover.

The transmission rubber ring 312 is partially wrapped outside the stainless steel sleeve 313.

In order to fix the stainless steel sleeve 313, the butt-welding mode can be adopted to fix the stainless steel sleeve 313 with the base pipe 31, and part of the stainless steel sleeve 313 can be coated when the transmission rubber ring 312 is coated, so that the stainless steel sleeve 313 is firmer, and the whole feeding roller is more beautiful.

Therefore, the feeding roller of the utility model has simple and reasonable structure and more convenient use.
