[0030] The embodiment of the present application provides a centering device 100, which can be used for centering material transportation, specifically for centering steel strips 200 in the production of prestressed pipe pile sleeves. The centering device 100 provided in the present application can realize centering guidance during the transportation of steel strips 200 of different specifications.

[0031] like Figure 1 As shown, the centering device 100 includes a driving component 110 and a limiting component 120, wherein the driving component 110 includes a rotating shaft 111 and two connecting rods 112 arranged opposite to each other, and one end of the two connecting rods 112 is rotatably connected to the rotating shaft 111; the limiting component 120 includes a sliding seat 121, a slider 122 and a guide wheel 123, and two sliders 122 and guide wheels 123 are each provided with a slide groove 127, and the sliding seat 121 is provided with a slide groove 127, and the slider 122 is slidably arranged in the slide groove 127, and one end of each connecting rod 112 away from the rotating shaft 111 is connected to a slider 122, and the two guide wheels 123 are respectively installed on the side of the slider 122 away from the connecting rod 112.

[0032] Combined Figure 3 and Figure 4As shown, illustratively, two connecting rods 112 are relatively arranged on two opposite sides of the rotating shaft 111. It can be understood that the rotating shaft 111 is a cylindrical structure, and the two connecting rods 112 are symmetrically arranged with the axis center of the rotating shaft 111. One end of the connecting rod 112 is rotatably connected to the end of the rotating shaft 111, so that under the action of an external driving force, the rotating shaft 111 can rotate and pull the connecting rod 112 to move closer to or away from the axis of the rotating shaft 111. Specifically, the external driving force can be a motor or a manual operation. The rotation of the rotating shaft 111 and the pulling operation of the connecting rod 112 can be achieved by connecting the motor to the rotating shaft 111 or manually twisting the rotating shaft 111 with a wrench.

[0033] Both the slide 121 and the slider 122 can be metal workpieces. The slide 121 is provided with a through slide groove 127 along its length direction. The two sliders 122 are relatively arranged at the two ends of the slide 121 and can slide in the slide groove 127. The ends of the two connecting rods 112 away from the rotating shaft 111 are rotatably connected with the slider 122 through a pin. During the rotation of the rotating shaft 111, due to the restriction of the slide groove 127 of the slide 121, the slider 122 can only move along the slide groove 127 under the traction of the connecting rod 112, thereby realizing the two sliders 122 to move closer to or away from each other. The guide wheel 123 is installed below the slide 121 and connected to the slider 122, so as to adjust the position following the slider 122. The steel belt 200 passes between the two guide wheels 123, so that the guide wheel 123 restricts the side of the steel belt 200, so as to adapt to the centering conveying and guiding of steel belts 200 of different widths.

[0034] Combination Figure 1 and Figure 2 As shown, in some embodiments, the centering device 100 also includes a guide assembly 130, the guide assembly 130 includes an upper guide plate 131 and a lower guide plate 132 that are relatively arranged, the upper guide plate 131 is installed on the side of the slide 121 away from the slider 122, the lower guide plate 132 is arranged on the side of the upper guide plate 131 away from the slide 121, and a conveying channel 134 is provided between the lower guide plate 132 and the upper guide plate 131.

[0035] Exemplarily, the upper guide plate 131 and the lower guide plate 132 can both be metal plates, and corresponding guide slopes can be set at the input end and the output end. The upper guide plate 131 can be fixedly set on the side of the slide 121 away from the slider 122 by bolt locking or welding. The lower guide plate 132 is set in parallel below the upper guide plate 131 at a certain interval to define a conveying channel 134. During the conveying process, the steel belt 200 passes through the conveying channel 134, so that the left and right sides of the steel belt 200 are restricted by the guide wheel 123, and the upper and lower sides of the steel belt 200 are restricted by the upper guide plate 131 and the lower guide plate 132, so as to guide the conveying direction of the steel belt 200 and always keep the output in a centered state.

[0036] Combination Figure 1 and Figure 2 As shown, in some embodiments, the guide assembly 130 further includes two cushion blocks 133 disposed opposite to each other. The two cushion blocks 133 are respectively located on both sides of the upper guide plate 131 , and two opposite sides of the cushion blocks 133 are respectively connected to the slide seat 121 and the lower guide plate 132 .

[0037] Exemplarily, the pad 133 may be a metal block with a certain thickness, and the two sides of the pad 133 are connected to the slide 121 and the lower guide plate 132 by bolts. The two pads 133 are arranged opposite to the two sides of the upper guide plate 131. It can be understood that, through the arrangement of the pads 133, a conveying channel 134 of a certain height is formed between the upper guide plate 131 and the lower guide plate 132. That is, the thickness of the pad 133 may be approximately the height of the conveying channel 134.

[0038] Combination Figure 1 and Figure 2 As shown, in some embodiments, the pad 133 is provided with a groove 135 , and the guide wheel 123 is inserted into the groove 135 .

[0039] Exemplarily, the groove surface of the groove 135 is an arc structure, and its arc surface size is adapted to the guide wheel 123, thereby providing an accommodation space for the guide wheel 123. At the same time, during the adjustment process of the guide wheel 123, the groove 135 can limit the sliding of the guide wheel 123 to prevent the guide wheel 123 from deviating during the sliding process.

[0040] like Figure 1 As shown, in some embodiments, the driving assembly 110 further includes a mounting seat 115 , the rotating shaft 111 passes through the mounting seat 115 and is rotatably connected to the mounting seat 115 , and both ends of the mounting seat 115 are connected to the sliding seat 121 .

[0041] Exemplarily, a through hole is provided at the center of the mounting seat 115, and the rotating shaft 111 passes through the through hole and forms a rotational fit with the mounting seat 115. Both ends of the mounting seat 115 are fastened and mounted on the slide seat 121 by bolts, so that the driving mechanism and the slide seat 121 are assembled and form a detachable structure, which is convenient for replacement or maintenance of internal components.

[0042] like Figure 1 As shown, in some embodiments, the driving assembly 110 also includes an upper connecting block 113 and a lower connecting block 114, the upper connecting block 113 is fixedly connected to the rotating shaft 111, the connecting rod 112 is arranged between the upper connecting block 113 and the lower connecting block 114, and the upper connecting block 113 and the lower connecting block 114 are rotatably connected at the same time through a pin shaft.

[0043] Exemplarily, the upper connecting block 113 and the lower connecting block 114 may both be circular sheet structures, and the upper connecting block 113 is fixedly connected to the end of the rotating shaft 111 and is coaxially arranged with the rotating shaft 111, so that they rotate synchronously during the rotation process of the rotating shaft 111. The connecting rod 112 is rotatably connected to the upper connecting block 113 and the lower connecting block 114 through a pin, so that the connecting rod 112 is installed between the upper connecting block 113 and the lower connecting block 114 to prevent the connecting rod 112 from falling off the rotating shaft 111.

[0044] It can be understood that in order to facilitate the connecting rod 112 to perform traction operation under the drive of the rotating shaft 111, the connecting rod 112 is installed on the edge of the upper connecting block 113.

[0045] like Figure 1 As shown, in some embodiments, the limiting assembly 120 further includes a plurality of pressing plates 124 , one side of the pressing plates 124 is connected to the slide seat 121 , and the side of the pressing plates 124 away from the slide seat 121 covers the edge of the slider 122 .

[0046] Exemplarily, the number of the pressing plates 124 may be two, four, etc., which may be selected according to the length of the slide 121 and actual needs. In this embodiment, the number of the pressing plates 124 may be four.

[0047] The pressure plate 124 can be a strip-shaped metal plate, one side of which is installed on the slide seat 121 by bolts, and the other side extends into the slide groove 127, thereby resisting the top of the slider 122, so that the slider 122 is confined in the slide groove 127, avoiding the slider 122 from sliding out from the top of the slide groove 127 during the sliding process.

[0048] Combination Figure 1 and Figure 2 As shown, in some embodiments, a limiting groove 128 is formed in the slide seat 121 , a connecting shaft 125 is provided on one side of the guide wheel 123 , and an end of the connecting shaft 125 away from the guide wheel 123 is penetrated by the limiting groove 128 and connected to the slide block 122 .

[0049] Exemplarily, the bottom plate of the slide 121 is provided with a through-limiting groove 128, and the limit has a certain length, so that after the connecting shaft 125 passes through the limiting groove 128 and connects with the slide 122, the maximum moving distance of the slide 122 is limited, thereby preventing the slide 122 from sliding out of the end of the slide groove 127. The slide 122 starts with the connecting hole, one end of the connecting shaft 125 is rotatably connected to the guide wheel 123, and the other end is installed in the connecting hole of the slide 122, so that the guide wheel 123 moves with the slide 122.

[0050] Combination Figure 1 and Figure 2 As shown, in some embodiments, a fixing bolt 126 is provided on the side of the slide seat 121 , and one end of the fixing bolt 126 passes through the slide seat 121 and is located in the slide groove 127 .

[0051] Exemplarily, one end of the set bolt 126 passes through the slide seat 121 and forms a threaded fit with the slide seat 121, so that the set bolt 126 can enter or exit the slide slot 127. During the adjustment of the guide wheel 123, it is necessary to obtain the size of the steel belt 200 and the distance between the two guide wheels 123 in advance, and then adjust the distance between the guide wheels 123 to match the steel belt 200. After the guide wheel 123 is adjusted, the set bolt 126 can be tightened to make the end of the set bolt 126 close to the slider 122, thereby limiting the displacement of the slider 122 and maintaining the stable positioning of the guide wheel 123.

[0052] Combination Figure 1 and Figure 4 As shown, in some embodiments, the connecting rod 112 has an arc-shaped structure.

[0053] Exemplarily, a depression is provided on the top side of the slider 122, so that the connecting rod 112 is installed in the depression. At the same time, the arc-shaped setting of the connecting rod 112 increases the sliding distance of the slider 122, and prevents the connecting rod 112 from abutting against the wall of the slider 122 in the depression and getting stuck.

[0054] An embodiment of the present application further provides a ferrule production device, comprising the centering device 100 in any of the above embodiments.

[0055] This embodiment has the centering device 100 in any of the above embodiments, and therefore has all the beneficial effects of the centering device 100 in any of the above embodiments, which will not be described in detail here.
