Description

Technical Field

[0001] The utility model relates to the field of coal mine conveying equipment, in particular to a buffer roller rubber ring press-fitting device. Background Art

[0002] Impact idlers are used at the receiving part of belt conveyors to slow down the impact of falling materials on conveyor belts. They are mainly developed for corrosive environments such as coal washing plants, coking plants, and chemical plants. They have a toughness that is more than 10 times that of ordinary metals, and are corrosion-resistant, flame-retardant, antistatic, and light in weight. They are widely used in mining. The polymer material used for the roller body has mechanical properties similar to bronze, good wear resistance, and good self-lubricating properties, and does not damage the belt. The impact idler has excellent anti-corrosion performance. The roller body and seals are made of polymer materials and are corrosion-resistant. When used in corrosive environments, the service life can reach more than 5 times that of ordinary rollers.

[0003] The buffer roller is mainly composed of a buffer rubber ring and a roller body. The buffer rubber ring should be put on the roller body. In the traditional process, the buffer rubber ring is put into the roller body by workers using hammering, which has the defects of low efficiency and high labor intensity. Therefore, it is necessary to produce a buffer roller rubber ring pressing equipment to solve the above problems. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 3 As shown, a buffer roller rubber ring press-fitting device includes a mounting bottom plate 1, a mounting top plate 2, a support rod 3, a base 4, a fixing assembly 5, a stamping cylinder 6, a stamping head 7 and a side pressure assembly 8. The upper and lower ends of the support rod 3 are respectively fixed on the mounting top plate 2 and the mounting bottom plate 1, the base 4 is fixed above the mounting bottom plate 1, the fixing assembly 5 is fixed above the base 4, the stamping cylinder 6 is fixed on the mounting top plate 2, the stamping head 7 is fixed at the power output end of the stamping cylinder 6 and corresponds to the top of the fixing assembly 5, and the side pressure assembly 8 is fixed on the support rod 3;

[0021] The fixing assembly 5 includes a screw rod 51 and a pressure cap 52. The lower end of the screw rod 51 is threadedly connected to the base 4, and the pressure cap 52 is threadedly connected to the upper end of the screw rod 51.

[0022] The support rod 3 is provided with multiple groups and corresponds to the outer periphery of the base 4. The side pressure assembly 8 includes an articulated bracket 81, a swing arm 82, a clamping wheel 83 and a first compression spring 84. The articulated bracket 81 is fixed on the support rod 3. The outer end of the swing arm 82 is hinged to the articulated bracket 81. The inner end of the swing arm 82 is tilted downward. The clamping wheel 83 is rotatably installed on the inner end of the swing arm 82. Multiple groups of clamping wheels 83 correspond to the outer periphery of the screw rod 51. The outer end of the first compression spring 84 is fixed on the support rod 3 and corresponds to the bottom of the articulated bracket 81. The inner end of the first compression spring 84 is fixed to the middle of the swing arm 82.

[0023] The buffer roller is mainly composed of a buffer rubber ring and a roller body. The roller body is placed vertically on the base 4, the screw 51 passes through the middle through hole of the roller body, and then the pressure cover 52 is installed on the upper end of the screw 51 and tightened to fix the roller body, and then the buffer rubber ring is placed above the pressure cover 52, and the equipment is started, so that the punching cylinder 6 drives the punching head 7 to downwardly sleeve the buffer rubber ring on the outer periphery of the roller body. The edge of the pressure cover 52 is rounded to facilitate the lower end of the buffer rubber ring to be stretched and sleeved on the roller body. When the buffer rubber ring is inserted downward for a distance, the lower end of the buffer rubber ring touches the clamping wheel 83, causing the lower end of the swing arm 82 to swing outward, and the first compression spring 84 is further compressed, so that the clamping wheel 83 applies a certain pressure to the outer wall of the buffer rubber ring during the subsequent insertion process of the buffer rubber ring, thereby avoiding the buffer rubber ring from tilting and causing difficulty in insertion during the process of the punching head 7 pressing down the buffer rubber ring. The advantage of this design is that it can reduce labor costs and improve the assembly efficiency of buffer rollers.

[0024] The base 4 includes an upper sleeve 41, a lower sleeve 42 and a second compression spring 43. The upper end of the lower sleeve 42 is open and the lower end is fixed on the mounting base plate 1. The lower end of the upper sleeve 41 is open. The lower end of the first compression spring 84 contacts the mounting base plate 1, and the upper end corresponds to the upper sleeve 41 and contacts the top of the upper sleeve 41. The upper end of the lower sleeve 42 is sleeved on the outer periphery of the lower end of the upper sleeve 41, and the lower end of the screw 51 is threadedly connected to the top of the upper sleeve 41.

[0025] When the punching cylinder 6 drives the punching head 7 to punch the buffer rubber ring downward, the upper sleeve 41 can slide downward relative to the lower sleeve 42 and compress the second compression spring 43 to play a buffering role, thereby preventing the punching head 7 and the buffer rubber ring from being damaged due to excessive instantaneous pressure when the punching head 7 hits the buffer rubber ring.

[0026] The fixing assembly 5 further includes a limiting collar 53 . An annular groove 531 is formed inside the lower end of the limiting collar 53 . The limiting collar 53 is mounted on the outer peripheral edge of the upper sleeve 41 through the annular groove 531 .

[0027] By replacing the limiting rings 53 of different thicknesses, the length of the buffer rubber ring pressed into the roller body can be adjusted for buffer rollers of different models and sizes. When the bottom of the buffer rubber ring is pressed into contact with the limiting ring 53, the expected pressing length is reached.

[0028] A circular hole 71 is provided in the middle of the lower part of the punch head 7 . During the punching process of the buffer rubber ring, the outer edge of the lower end of the punch head 7 contacts the buffer rubber ring and presses it downward, and the roller body is inserted into the circular hole 71 .

[0029] The support rods 3 and the side pressure components 8 are respectively arranged in four groups and are evenly distributed on the periphery of the base 4, so that the pressure applied by the side pressure components 8 on the buffer rubber ring is more uniform, ensuring that the buffer rubber ring is always vertically upward during the stamping process.

[0030] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
