Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, a chain tensioner for cloth conveying comprises a tension spring 8, a connecting rod 7, a bearing seat 9, a tension gear 10 and two guide rails 1 arranged in parallel, a fixed plate 2 is fixedly connected between the two guide rails 1, a spring baffle is fixedly connected to the fixed plate 2, the connecting rod 7 is slidably connected to the spring baffle, one end of the connecting rod 7 is fixedly connected to a circular baffle 6, the spring baffle comprises an upper spring baffle 5 and a lower spring baffle which are identical in structure, the lower spring baffle is fixed to the fixed plate 2, the lower spring baffle is provided with a semicircular groove with an upward opening, the top of the lower spring baffle extends outwards to form a connecting lug, the semicircular groove of the upper spring baffle 5 is provided with a downward opening, when the upper spring baffle 5 is matched with the lower spring baffle, the connecting lug is connected through a fixing bolt, the semicircular groove of the upper spring baffle 5 is matched with the semicircular groove of the lower spring baffle to form a channel of the connecting, this kind of detachable construction of spring bezel has made things convenient for the installation of connecting rod 7, and the maintenance of the connecting rod 7 of being convenient for can also play the effect of sheltering from tensioning spring 8, makes tensioning spring 8's one end be in fixed state.
A fixed seat 3 is fixedly connected to the fixed plate 2, a threaded hole is formed in the fixed seat 3, a thrust bolt 4 is connected to the threaded hole in a threaded manner, the end portion of the thrust bolt 4 abuts against one side of a circular baffle 6, the circular baffle 6 is positioned between the fixed seat 3 and a spring baffle, two sliders 701 are fixedly connected to the outer wall of the other end of the connecting rod 7, the sliders 701 correspond to the guide rails 1 one by one, the sliders 701 are slidably connected to the guide rails 1, a stop block 702 is further arranged on the outer wall of the connecting rod 7, a tension spring 8 is sleeved on the connecting rod 7, one end of the tension spring 8 is pressed on the spring baffle, the other end of the tension spring 8 is pressed on the stop block 702, the other end of the connecting rod 7 abuts against a bearing seat 9, the bearing seat 9 is slidably connected to the guide rails 1, in the embodiment, a sliding groove is formed, the bearing block 9 is rotatably connected with a rotating shaft 11, the periphery of the rotating shaft 11 is fixedly connected with a tensioning gear 10, the rotating shaft 11 is fixedly connected with a disc 12, and the disc 12 is arranged on the outer side of the tensioning gear 10 and is spaced from the tensioning gear 10.
If connecting rod 7 or bearing frame 9 block, can not in time tensioning the chain, the chain will take place to become flexible, probably produces the risk of taking off the tooth, if the chain breaks away from the meshing, disc 12 can restrict the space that the chain moved upwards, prevents that the chain from flying out, has improved chain tensioning adjusting device's security.
During installation, the end, with the sliding block 701, of the connecting rod 7 is abutted to the bearing seat 9, the other end of the connecting rod 7 is installed in the semicircular groove of the lower spring baffle plate, the upper spring baffle plate 5 is abutted to the lower spring baffle plate, the connecting lug is fixedly connected through the fixing bolt, the thrust bolt 4 is screwed into the threaded hole of the fixing seat 3, the end portion of the thrust bolt 4 is abutted to one side of the circular baffle plate 6, the thrust bolt 4 is further rotated at the moment, the thrust bolt 4 pushes the circular baffle plate 6 to move rightwards, and therefore the tension spring 8 is compressed and is in a working state, and the tension spring 8 is in a working state.
During normal work, tensioning spring 8 one end is pressed on the spring baffle, the other end is pressed on dog 702, tensioning spring 8 is in compression state, tensioning spring 8's elasticity equals the tensile force of chain, the chain is in normal operating condition, when the chain is not hard up gradually because of long-time high load's operation, the tensile force of chain is less than tensioning spring 8's elasticity, at this moment tensioning spring 8 will drive connecting rod 7 right motion, the tip of connecting rod 7 then can promote bearing frame 9 right motion, tensioning gear 10 right tensioning chain, and the space can appear between thrust bolt 4 and the circular baffle 6 this moment, it rotates thrust bolt 4 to need the staff right, make the tensile force rebalance of tensioning spring 8's elasticity and the tensile force of chain.
