Abstract
A drive chain tensioner comprising: a chute (1); the tensioning wheel base (2) is positioned in the sliding groove and can slide; the first tensioning chain wheel (3) and the second tensioning chain wheel (4) are respectively connected with a first fixing shaft and a second fixing shaft which are fixed on the tensioning wheel base (2) in a rotating mode, the first tensioning chain wheel (3) and the second tensioning chain wheel (4) are respectively located on the two outer sides of the chain to tension the chain, and the first tensioning chain wheel (3) and/or the second tensioning chain wheel (4) are/is connected with a screw and nut mechanism (7) for adjusting the distance between the first tensioning chain wheel and the second tensioning chain wheel. The device disclosed by the invention can enable the driving chain wheel to tension the loose edge of the chain no matter the driving chain wheel rotates forwards or reversely, so that the chain wrap angle of the driving chain wheel and the driven chain wheel is ensured, the chain is prevented from shaking and jumping, and the chain is more stable to operate.
Description
Technical Field
The utility model relates to a drive chain overspeed device tensioner can be applicable to the tensioning of SQ filament cutter copper bar chain final drive chain.
Background
At present, a main transmission chain tensioning device of a filament cutter is a tensioning wheel with a spring and capable of stretching. The main transmission chain of the shredder usually works in a reverse rotation state, and the tension wheel does not play any role in the reverse rotation.
SUMMERY OF THE UTILITY MODEL
The present disclosure provides a drive chain tensioning device, two tensioning sprocket are located two outsides of chain, no matter the chain corotation is still the reversal, all have a tensioning sprocket to carry out the tensioning to the slack side of chain.
According to an aspect of an embodiment of the present disclosure, a drive chain tensioner includes: a chute; the tensioning wheel base is positioned in the sliding groove and can slide; the first tensioning chain wheel and the second tensioning chain wheel are respectively and rotatably connected with a first fixing shaft and a second fixing shaft which are fixed on the tensioning wheel base, the first tensioning chain wheel and the second tensioning chain wheel are respectively positioned on two outer sides of the chain to tension the chain, and the first tensioning chain wheel and/or the second tensioning chain wheel are/is connected with a screw and nut mechanism for adjusting the distance between the first tensioning chain wheel and the second tensioning chain wheel.
In the above transmission chain tensioning device, the first fixed shaft is located in the slideway of the tensioning wheel base and connected to a nut of the screw-nut mechanism.
In the above-mentioned transmission chain tensioning device, the second fixed shaft is located in another slideway of the tensioning wheel base and connected with a nut of another screw-nut mechanism.

Detailed Description
Referring to fig. 1-4, a drive chain tensioner comprises a chute 1, a tensioner base 2, a first tensioner sprocket 3 and a second tensioner sprocket 4. The chute 1 is fixed to the base of the apparatus on which the chain 6 to be tensioned is located, for example the base of an SQ35 shredder. The tensioning wheel base 2 is positioned in the sliding groove 1 and can slide. The first tensioning chain wheel 3 and the second tensioning chain wheel 4 are respectively and rotatably connected with a first fixed shaft and a second fixed shaft which are fixed on the tensioning wheel base 2. The first fixed shaft for mounting the first tensioning chain wheel 3 is arranged in the slideway 5 of the tensioning wheel base 2 and is connected with a nut of a screw-nut mechanism. The distance between the first tensioning chain wheel 3 and the second tensioning chain wheel 4 can be changed by rotating the screw rod 7, and the tightness of the chain 6 is adjusted to be in a proper state. Alternatively, the second tensioning sprocket 4 may be connected to a spindle nut mechanism, or the first tensioning sprocket 3 and the second tensioning sprocket 4 may be connected to a spindle nut mechanism.
As shown in fig. 5, when the chain 6 is running in the forward direction, the driving sprocket 8 rotates counterclockwise, the upper part of the chain 6 is a tight side, and is in a tight and straight state, so that the first tension sprocket 3 drives the tension pulley base 2 to move upward in the chute 1, and the second tension sprocket 4 also moves at the same time, thereby tensioning the loose side of the chain 6.
As shown in fig. 6, when the chain 6 runs in the reverse direction, the driving sprocket 8 rotates clockwise, the lower part of the chain 6 is a tight edge, and is in a tight and straight state, so that the second tensioning sprocket 4 drives the tensioning wheel base 2 to move downwards in the chute 1, and the first tensioning sprocket 3 also moves at the same time, thereby tensioning the loose edge of the chain 6.
The device disclosed can make the drive sprocket 8 not only rotate forward but also rotate reversely, can both tension the slack side of the chain 6, ensure the chain wrap angle of the drive sprocket 8 and the driven sprocket 9, avoid the shaking and the tooth jumping of the chain 6, and make the operation of the copper bar chain of the SQ35 shredder more stable.
