A sliding plate type tensioning mechanism comprises an installation base body, a sliding shaft seat and a positioning plate, wherein the sliding shaft seat is connected to the installation base body in a sliding mode, a lead screw is arranged between the positioning plate and the sliding shaft seat, a pressure spring is sleeved on the lead screw, one end of the lead screw is connected to the sliding shaft seat, and the other end of the lead screw is connected to the positioning plate through a nut.
Preferably, the sliding shaft seat is connected to the mounting seat body in a sliding manner through a sliding rail.
Preferably, the nut is a double nut.
Preferably, one end of the screw rod is fixed on the screw rod connecting block, and the screw rod connecting block is connected to the sliding shaft seat through a bolt.
Preferably, the positioning plate is a movable positioning plate and is connected to the adjusting assembly, and the adjusting assembly drives the movable positioning plate to perform reciprocating adjustment along the length direction of the screw rod.
Preferably, the adjusting assembly comprises a supporting fixing part and an adjusting screw rod, and two ends of the adjusting screw rod are respectively connected to the supporting fixing part and the movable positioning plate through adjusting nuts.
Preferably, the sliding shaft seat is a bearing seat.
Has the advantages that: the utility model provides a slide formula tight mechanism that rises is applicable to transmission shaft or sprocket tight suitable for that rises, the installation and the adjustment of being convenient for, transmission shaft or sprocket under the unbalanced condition of atress, can carry out the automatic fine setting of elasticity under the pressure spring elastic force effect, the chain produces vibration, jumps the tooth or takes off the chain phenomenon because of bearing the tension of uneven balance when can reducing equipment operation.

Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
Example 1:
as shown in fig. 1-2, an embodiment of the present invention provides a sliding plate type tensioning mechanism, including an installation base 1, a sliding shaft seat 2 and a positioning plate 3, the sliding shaft seat 2 is slidably connected to the installation base 1, a screw rod 4 is disposed between the positioning plate 3 and the sliding shaft seat 2, the screw rod 4 is sleeved with a pressure spring 5, one end of the screw rod 4 is connected to the sliding shaft seat 2, the other end of the screw rod is connected to the positioning plate 3 through a nut 9, the mounting nut 9 is a double nut, one of the two nuts is a positioning nut 91, and the other is a locking nut 92, when in installation, the positioning nut 91 compresses the pressure spring, and then the tensioning mechanism is fixed to a corresponding position of the equipment (such as a side plate of the equipment casing) by cooperating with a transmission shaft or a sprocket, the installation base 1 is provided with a fixing hole, related fixation is completed through the fixing hole, the positioning nut 91 is released after the fixation is completed, so that the spring is restored to a natural straight state, and then the locking nut 92 and the positioning nut 91 are fixed, so that the transmission shaft or the sprocket has a certain elastic expansion amount; the automatic fine adjustment device can perform automatic elastic fine adjustment under the action of the elastic force of the pressure spring, and can reduce the phenomena of vibration, tooth jumping or chain release caused by the fact that a chain bears uneven tension when the equipment runs.
Specifically, the sliding shaft seat 2 is a bearing seat, a transmission shaft or a chain wheel shaft of the equipment is connected to the bearing seat, the sliding shaft seat 2 is connected to the installation seat body 1 through a sliding rail 6 in a sliding mode, one end of the lead screw 4 is fixed to the lead screw connecting block 7, and the lead screw connecting block 7 is connected to the sliding shaft seat 2 through a bolt.
In order to ensure a certain tensioning stroke, the positioning plate 3 is a movable positioning plate, which is connected to a plurality of adjusting assemblies, the adjusting assemblies drive the movable positioning plate to perform reciprocating adjustment along the length direction of the lead screw 4, each adjusting assembly comprises a supporting and fixing part 81 and an adjusting screw 82, and two ends of the adjusting screw 82 are respectively connected to the supporting and fixing part 81 and the movable positioning plate through adjusting nuts 83.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
