Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0041] Please refer to Figures 1 to 4 , the present utility model provides a swing-type rubber compound conveying device, which includes a first support frame 1, a rotating shaft assembly 3 provided on the first support frame 1, and a conveying assembly 8 rotatably connected to the rotating shaft assembly 3 at the lower side; it further includes a second support frame 2, a first driving mechanism 4 provided on the second support frame 2, a swing plate 5 horizontally located above the second support frame 2 and drivingly connected to the output shaft of the first driving mechanism 4, a movable assembly 6 vertically provided on the swing plate 5, and a first support 7 provided at the bottom of the conveying assembly 8 and having a slot hole 701.

[0042] It can be understood that the conveying assembly 8 has an inclined conveying portion and a horizontal conveying portion, and the horizontal conveying portion is located above the calender roll of the calender 17, so as to ensure that the strip-shaped rubber compound can be conveyed into the calender 17 for calendering and forming. When the swing-type rubber compound conveying device works, the conveying assembly 8 swings with the rotating shaft assembly 3 as the swing center.

[0043] The first driving mechanism 4 generally uses a driving motor, and its output shaft passes upward through the second support frame 2 and can be connected to the bottom of the swing plate 5 by means of a coupling or the like, so as to drive the swing plate 5 to swing 360° with the output shaft of the first driving mechanism 4 as the swing center. During the swinging process of the swing plate 5, the movable assembly 6 located on the swing plate 5 will also swing with the swing plate 5, and the movable assembly 6 always maintains an active connection relationship with the slot hole 701 at the bottom of the first support 7. Thus, in order to adapt to the change in the positional relationship of the movable assembly 6, the first support 7 and the upper conveying assembly 8 should swing accordingly, and the conveying assembly 8 can swing left and right with the rotating shaft assembly 3 as the swing center.

[0044] Different from the prior art, a chute 501 is provided on the swing plate 5 of the present utility model. Further, the length direction of the chute 501 is consistent with the length direction of the swing plate 5, and a lead screw 18 is rotatably provided in the chute 501 along the length direction of the chute 501; the movable assembly 6 is movably sleeved on the lead screw 18; one end of the lead screw 18 extends out of the swing plate 5. Thus, by rotating the lead screw 18, the movable assembly 6 can slide in the chute 501, and the position of the movable assembly 6 on the swing plate 5 can be changed. While the swing center of the swing plate 5 remains unchanged, when the position of the movable assembly 6 on the swing plate 5 changes, the area of the circular region formed by its swing trajectory will also change. When the area of the circular region formed by the swing trajectory of the movable assembly 6 increases, the swing amplitude of the conveying assembly 8 will also increase, and when the area of the circular region formed by the swing trajectory of the movable assembly 6 decreases, the swing amplitude of the conveying assembly 8 will also decrease.

[0045] It can be seen that by changing the position of the movable assembly 6 on the swing plate 5, the swing amplitude of the conveying assembly 8 can be adjusted. Therefore, the width of the calendered PVC film can be changed to meet the production requirements of diversified PVC films.

[0046] As Figure 2 and Figure 3 shown, in a preferred embodiment of the present utility model, the movable assembly 6 includes a sliding seat 601 and a swing rod 602; the sliding seat 601 is movably sleeved on the lead screw 18, and the bottom of the sliding seat 601 contacts the bottom wall of the chute 501, so that the swing plate 5 can share part of the weight of the sliding seat 601, and the service life of the lead screw 18 can be extended; and the swing rod 602 is vertically fixed on the sliding seat 601, and the upper end of the swing rod 602 passes upward through the slot hole 701. The swing rod 602 is preferably cylindrical, and when the swing rod 602 moves in the slot hole 701, the first support 7 can also swing flexibly.

[0047] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in a preferred embodiment of the present utility model, the conveying assembly 8 includes a conveying frame 81, a driving roller 84, a driven roller 82, a second driving mechanism 83, and a conveying belt 86. The conveying frame 81 includes two parallel side plates 811 and a third support 812 connected to the bottoms of the two side plates 811. The third support 812 is connected to the first support frame 1 through a rotating shaft assembly 3, so that the conveying assembly 8 can swing.

[0048] Specifically, the driven roller 82 is arranged at both ends of the conveying frame 81. The second driving mechanism 83 is generally a driving motor, which is installed above the conveying frame 81 through a steel frame structure. The active roller 84 is arranged opposite to the second driving mechanism 83, and can be installed below the conveying frame 81 through a steel frame structure, and the conveying belt 86 for conveying the strip rubber material is wound around the active roller 84 and the driven roller 82 at the same time. Compared with the existing conveying assembly 8, in the conveying assembly 8 provided by the utility model, the active roller 84 is not installed at the input end or the output end of the conveying assembly 8, so that the second driving mechanism 83 can be avoided from being close to the mixing mill or the calender 17, so that the second driving mechanism 83 will not be exposed to a high temperature environment for a long time, the service life of the second driving mechanism 83 can be extended, and the safety hazard when the equipment is used is small.

[0049] In order to enable the active roller 84 to rotate and the conveying belt 86 to operate, the conveying assembly 8 also includes a transmission mechanism 87; the transmission mechanism 87 is simultaneously connected to the output shaft of the second driving mechanism 83 and the active roller 84, and the transmission mechanism 87 can be a high-temperature resistant chain transmission mechanism 87, specifically including a driving sprocket 871 coaxially arranged with the output shaft of the second driving mechanism 83, a driven sprocket 872 coaxially arranged with the active roller 84, and a transmission chain 873 simultaneously wound around the driving sprocket 871 and the driven sprocket 872.

[0050] like Figure 2 and Figure 5 As shown, in a preferred embodiment of the present utility model, the conveying assembly 8 further includes a supporting roller 88; a plurality of supporting rollers 88 are provided, and the supporting rollers 88 are rotatably arranged on the conveying frame 81. The supporting frame is used to support the conveying belt 86 so that the conveying belt 86 remains in an unfolded state, thereby enabling material conveying operations.

[0051] like Figure 1 and Figure 7 As shown, in a preferred embodiment of the present utility model, the conveying assembly 8 also includes a tensioning roller 89, two U-shaped guide frames 9, a bearing seat 10 and a gripping rod 11.

[0052] Specifically, the tension roller 89 is arranged below the conveyor frame 81, and the tension roller 89 cooperates with the aforementioned support roller 88 to keep the conveyor belt 86 in a tensioned state (the length direction of the support roller 88 and the tension roller 89 is consistent with the width direction of the conveyor belt 86). The two U-shaped guide frames 9 are respectively located outside the two axial ends of the tension roller 89, and the U-shaped guide frame 9 and the bottom of the conveyor frame 81 are fixedly connected. The bearing seat 10 is installed on the U-shaped guide frame 9, and the axial end of the tension roller 89 is rotatably connected to the bearing seat 10, so that the tension roller 89 can be installed below the conveyor frame 81.

[0053] In order to adjust the tension state of the conveyor belt 86, a vertical guide bar (not shown in the drawings) can be provided inside the U-shaped guide frame 9, and the bearing seat 10 can be slidably arranged on the guide bar. Thus, the distance between the tension roller 89 and the conveyor frame 81 can be adjusted, so that the tension state of the conveyor belt 86 can be changed.

[0054] Specifically, the grip rod 11 is connected to the bottoms of the two bearing seats 10 at the same time, so that the production personnel can move the two bearing seats 10 simultaneously, which is convenient for the production personnel to adjust the distance between the tension roller 89 and the conveyor frame 81.

[0055] As Figure 7 shown, in a preferred embodiment of the present invention, a movable screw 12 is connected to the bottom of the grip rod 11, and the movable screw 12 is movably connected to the bottom of the U-shaped guide frame 9, and it can move up and down during the process of the production personnel moving the worm; a nut 13 is sleeved on the movable screw 12, and the nut 13 is located inside the U-shaped guide frame 9, so that the movable screw 12 can be fixed by means of the nut 13, so that when the tension state of the conveyor belt 86 does not need to be adjusted, the tension roller 89 cannot move.

[0056] As Figure 1 shown, in a preferred embodiment of the present invention, the swing-type rubber compound conveying device further includes a support beam 14 and a second support 15; both ends of the support beam 14 are connected to the two side walls of the calender 17; the second support 15 is connected to the bottom of the discharge end of the conveying assembly 8, and the second support 15 is movably arranged on the support beam 14. During the process of the conveying assembly 8 swinging and discharging, the second support can move on the support beam 14. Therefore, the support beam 14 plays a role in supporting the conveying assembly 8, and at the same time, cooperating with the support of the first support frame 1 for the conveying assembly 8, the conveying assembly 8 has good balance and stability during the swinging process, and no production safety accidents will occur.

[0057] As Figure 1 shown, in a preferred embodiment of the present invention, a groove 141 is provided on the support beam 14, the second support 15 is located in the groove 141, and the inner wall of the groove 141 is coated with lubricating oil. The lubricating oil plays a role in reducing the friction between the second support 15 and the support beam 14, thereby reducing the wear degree of the surface of the support beam 14.

[0058] As Figure 1 shown, in a preferred embodiment of the present invention, a rotating rod 16 is provided at one end of the lead screw 18 extending out of the swing plate 5, and the rotating rod 16 and the lead screw 18 are in a cross shape. The arrangement of the rotating rod 16 facilitates the rotation of the lead screw 18. Of course, in order to facilitate the rotation of the lead screw 18, the rotating rod 16 can also be designed into a structure similar to a steering wheel.

[0059] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
