A kind of Novel conveyer belt tensioning apparatus
Technical field
The invention belongs to rotor spinning machines, and in particular to a kind of Novel conveyer belt tensioning apparatus.
Background technique
Rotor spinning machine is a kind of faster novel spinning equipment of development, the conveyor motor that users factory uses at present
Transmission mechanism and strainer are separately positioned on headstock tailstock two sides, and personnel walk back and forth distance in debugging process, debugging
Complexity, the easy sideslip of conveyer belt, causes cylinder yarn to wear in the process of running, brings economic loss to user.New device will be driven
Mechanism and strainer are designed in the same side, and roller uses arc surface structure, compared with original structure it is effective have obviously change
It is kind.
Summary of the invention
The purpose of the present invention is to provide a kind of Novel conveyer belt tensioning apparatus.The technical issues of present invention can solve is just
It is rotor spinning machine cylinder yarn transportation problem, pervious complicated in mechanical structure, cylinder yarn is easy to wear during transport, installs more
Simple and compact using new structure dependent on equipment adjustment, mounting and adjusting is convenient, and manufacturing cost is low, which can effectively prevent
Cylinder yarn abrasion, simplifies assembly difficulty, reduces the maintenance cost for using producer.
The technical solution adopted by the present invention:A kind of Novel conveyer belt tensioning apparatus, it includes fixed plate, motor base, electricity
Machine speed reducer assembly, the first pressure roller, the second pressure roller, drive roll, idler roller, first support, second support, screw rod and adjusting spiral shell
Mother, first support and second support are each attached in fixed plate, and first support is located at the surface of second support, at first
It is one in front and one in back horizontally provided with the first pressure roller and the second pressure roller on frame, the first pressure roller and the second pressure roller are located in first support
Between be horizontally provided with drive roll, motor base is fixed in fixed plate, and motor reducer assembly is fixed on motor base,
And the output shaft of motor reducer assembly and drive roll are sequentially connected;Idler roller is set up on the secondary support bracket, in second support
It is internally provided with screw rod, the lower end of second support is provided with adjusting nut, adjusting nut is connect with screw rod, by adjusting adjusting
Nut is to realize adjusting to screw rod, screw rod and idler roller apical grafting, and when screw rod up and down adjustment, the height of idler roller is up and down with silk
Bar moves together.
Further, the first support and second support are the plate-like connecting member groups that the left and right sides is symmetrical structure
At.
Further, the centerline height of the first pressure roller and the second pressure roller differs certain distance, and the first pressure roller and second
The centerline height of pressure roller is above drive roll.
The present invention compared with prior art the beneficial effect is that:The present invention overcomes the deficiencies of former mechanical structure, provide
A kind of novel transmission mechanism and strainer design the conveying belt tensioning mechanism in the same side.Simple and compact for structure, installation is adjusted
Just, manufacturing cost is low for perfect square, which can effectively prevent belt deflection, cylinder yarn abrasion, reduces producer's maintenance cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the top view of Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, a kind of Novel conveyer belt tensioning apparatus, it includes that fixed plate 1, motor base 2, motor subtract
Fast device assembly 3, the first pressure roller 4, the second pressure roller 5, drive roll 6, idler roller 7, first support 8, second support 9, screw rod and adjusting
Nut, first support 8 and second support 9 are each attached in fixed plate 1, and first support 8 is located at the surface of second support 9,
It is one in front and one in back horizontally provided with the first pressure roller 4 and the second pressure roller 5 in first support 8, the first pressure is located in first support 8
Drive roll 6 is horizontally provided between roller 4 and the second pressure roller 5, motor base 2 is fixed in fixed plate 1, motor reducer assembly
3 are fixed on motor base 2, and the output shaft of motor reducer assembly 3 and drive roll 6 are sequentially connected;Idler roller 7 is erected at
On two brackets 9, it is internally provided with screw rod in second support 9, the lower end of second support 9 is provided with adjusting nut 10, is adjusted
Nut 10 is connect with screw rod, by adjusting adjusting nut 10 to realize the adjusting to screw rod, screw rod and 7 apical grafting of idler roller, silk
When bar up and down adjustment, the height of idler roller 7 is moved with screw rod up and down.
The first support 8 and second support 9 are that the plate-like connecting member that the left and right sides is symmetrical structure forms.First pressure
The centerline height of roller 4 and the second pressure roller 5 differs certain distance, and the centerline height of the first pressure roller 4 and the second pressure roller 5 is high
In drive roll 6.
