Utility model content
In order to solve the problems, such as that existing rubber roll causes aluminum substrate to skid during aluminum substrate is transmitted, the utility model provides
A kind of thread roller for preventing from skidding.
The utility model is achieved by the following technical solution：A kind of thread roller for preventing from skidding, including roll shaft,
Roll shaft both sides are provided with connecting portion, and roll shaft surface is provided with thread groove, and the section of the thread groove is triangle, the tooth of thread groove
Type angle is 90 °~170 °.
Further, the thread form angle of the thread groove is 130 °~170 °.
Further, the width that the thread groove is located at roll shaft surface is 0.5 mm~3mm, and the pitch of the thread groove is
0.5 mm~30mm.
Further, the lift angle of the thread groove is 9 °~26 °.
Further, the thread groove is provided with chamfered section with roll shaft surface contact position.
The utility model is a kind of to prevent that beneficial effect caused by the thread roller of skidding from being：Roll shaft both sides are provided with connection
Portion, it is erected at by connecting portion on rollers, while connecting portion is connected with power set, band action roller shaft rotates, and completes aluminium plate
The transmission of base；In order to prevent aluminum substrate from producing slip with respect to roll surface, thread groove, while section of thread groove are provided with roll shaft surface
Face is triangle, increases the frictional force of roll surface, in order to prevent the thread form angle of thread groove too small, causes roll shaft edge to aluminum substrate
Cause to damage, the thread form angle of thread groove is arranged to 90 °~170 °, so solve existing rubber roll during aluminum substrate is transmitted
The problem of causing aluminum substrate to skid.
Brief description of the drawings
Fig. 1 is the utility model thread roller main body schematic diagram.
Fig. 2 is the utility model thread roller close-up schematic view.
In figure：1 roll shaft, 101 roll shaft surfaces, 102 thread grooves, 103 chamfered sections, 2 connecting portions.
Embodiment
It will describe in detail in conjunction with specific embodiments with reference to the accompanying drawings below：
As seen from the figure, a kind of thread roller for preventing from skidding, including roll shaft 1, connecting portion 2, roll shaft are provided with the both sides of roll shaft 1
Surface 101 is provided with thread groove 102, and the section of the thread groove 102 is triangle, the thread form angle of thread groove 102 for 90 °~
170°。
The utility model a kind of thread roller for preventing from skidding, connecting portion 2 is provided with the both sides of roll shaft 1 when specifically used,
It is erected at by connecting portion 2 on rollers, while connecting portion 2 is connected with the power set of roll shaft 1, band action roller shaft 1 rotates, complete
Into the transmission of aluminum substrate；In order to prevent aluminum substrate from producing slip with respect to roll surface, roll shaft surface 101 is provided with thread groove 102, together
When thread groove 102 section be triangle, increase the frictional force of roll surface, in order to prevent the thread form angle of thread groove 102 too small, lead
Cause the edge of roll shaft 1 to cause to damage to aluminum substrate, the thread form angle of thread groove 102 is arranged to 90 °~170 °, so solved existing
Rubber roll during transmitting aluminum substrate cause aluminum substrate to skid the problem of.
Further, for the ease of processing, while prevent aluminum substrate from skidding, the thread form angle of the thread groove for 130 °~
170°。
Further, for the ease of processing, while prevent aluminum substrate from skidding, the thread groove 102 is located at roll shaft surface 101
Width be 0.5 mm~3mm, the pitch of the thread groove 102 is 0.5 mm~30mm.
Further, for the ease of processing, while prevent aluminum substrate from skidding, the lift angle of the thread groove 102 for 9 °~
