DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in a variety of ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0024] like Figures 1 to 6 As shown together, the belt loading device of the circular mold vulcanization automatic production line includes a top frame 1, and the lower part of the top frame 1 is fixedly connected to a belt support seat 11, and a plurality of belt support blocks 2 are installed on the belt support seat 11 and are radially slidably arranged along the belt support seat 11. A belt sliding connection device 3 is respectively provided between each of the belt support blocks 2 and the belt support seat 11, and the belt support blocks 2 are commonly connected to a belt support control device 4.

[0025] The belt support control device 4 controls the plurality of belt support blocks 2 to slide and expand toward the outside of the belt support seat 11, or to slide and retract toward the inside of the belt support seat 11, and the belt support blocks 2 can support the belt 7 when they are expanded. The inside and outside of the belt support seat 11 are defined by the outer edge of the belt support seat 11, and this definition is only used to better illustrate the positional relationship of this embodiment, and is not intended to limit the scope of protection.

[0026] The belt control device 4 of this embodiment includes a belt transmission seat 41 which is vertically slidably mounted on the belt support seat 11 and is located above the belt support seat 11, and a belt transmission rod 42 is respectively hingedly connected between the belt transmission seat 41 and each of the belt support blocks 2; a vertically arranged belt control screw 43 is rotatably mounted on the belt support seat 11, and a belt control screw hole which cooperates with the belt control screw 43 is provided on the belt transmission seat 41, and the belt control screw 43 is connected to a belt control motor 44. When the belt control motor 44 drives the belt control screw 43 to rotate forward, due to the thread guide effect, the belt transmission seat 41 moves downward, and a plurality of the belt transmission rods 42 push the corresponding belt support blocks 2 outward from the belt support seat 11, so that the belt support blocks 2 slide and unfold to the outside of the belt support seat 11; on the contrary, when the belt control motor 44 drives the belt control screw 43 to rotate reversely, a plurality of the belt support blocks 2 slide back.

[0027] The support belt sliding connection device 3 is used to improve the stability of the support belt block 2 during the sliding process and the stability of the support belt after it is unfolded. In this embodiment, the support belt sliding connection device 3 includes a support belt slide bar 31 fixedly arranged on the support belt block 2, and the support belt seat 11 is provided with a support belt slide groove 32 corresponding to the support belt slide bar 31.

[0028] Preferably, in this embodiment, at least two support seat connecting rods 12 are fixedly connected between the top frame 1 and the support belt seat 11, and the support belt transmission seat 41 is slidably mounted on at least two of the support seat connecting rods 12, that is, the support seat connecting rods 12 also serve as sliding rods of the support belt transmission seat 41. This embodiment shows that there are two support seat connecting rods 12. The top end of the support belt control screw 43 is rotatably connected to the top frame 1, that is, the support belt control screw 43 is rotatably mounted between the top frame 1 and the support belt seat 11. The support belt control motor 44 is installed on the top frame 1, and this embodiment shows that the output end of the support belt control motor 44 is connected to the support belt control screw 43 by a belt transmission. Through the above-mentioned arrangement, the overall structure of this embodiment can be simplified, making the structure of this embodiment more compact.

[0029] Preferably, the support belt block 2 is arranged in a fan-shaped ring shape. In this way, the outer side surface of the support belt block 2 is arc-shaped. When a plurality of the support belt blocks 2 support the belt 7, it can be supported into a nearly circular shape, which is conducive to direct press-fitting into a circular mold. At the same time, when the support belt blocks 2 are gathered together, it is not easy for them to interfere with each other. This embodiment shows that there are eight support belt blocks 2. Preferably, the eight support belt blocks 2 are evenly arranged along the circumference of the support belt seat 11.

[0030] The top frame 1 is provided with a support block deployment sensor 45 and a support block retraction sensor 46, and the support belt transmission seat 41 is provided with a support block position sensing part 47 corresponding to the support block deployment sensor 45 and the support block retraction sensor 46. Of course, the support block deployment sensor 45 and the support block retraction sensor 46 are connected to the controller, and the output signal of the controller is connected to the support belt control motor 44. The support block deployment sensor 45 and the support block retraction sensor 46 respectively detect the low position and the high position of the support belt transmission seat 41, so as to control the deployment position and the retraction position of the support belt block 2, thereby improving the automation degree of the deployment and retraction of the support belt block 2 in this embodiment. Because the support belt seat 11 is fixedly connected to the top frame 1, the support block deployment sensor 45 and the support block retraction sensor 46 are installed on the support belt seat 11, and the effect is the same.

[0031] The support block deployment sensor 45 and the support block retraction sensor 46 are connected to the deployment position adjustment device and the retraction position adjustment device respectively. This embodiment shows that a support block sensing mounting plate is provided on the top frame 1, and a support block sensing mounting long hole is provided on the support block deployment sensor 45, and a bolt passing through the support block sensing mounting long hole is threadedly installed to serve as the deployment position adjustment device, and a bolt passing through the support block sensing mounting long hole is threadedly installed on the support block retraction sensor 46 to serve as the retraction position adjustment device. Among them, the adjustability of the deployment position of the support belt block 2 enables the support belt block 2 to support belts 7 of different lengths, which broadens the scope of use of this embodiment.

[0032] The top frame 1 is vertically slidably mounted with an annular press-fitting seat 5 located outside the belt support seat 11, and a plurality of belt pressing blocks 6 are arranged on the annular press-fitting seat 5. A press-fitting driving device 59 is arranged between the annular press-fitting seat 5 and the top frame 1. When the plurality of belt support blocks 2 are unfolded to support the belt 7, the press-fitting driving device 59 drives the annular press-fitting seat 5 to slide downward, and the plurality of belt pressing blocks 6 can press the supported belt 7 downward to separate it from the belt support block 2, and press the belt 7 into the circular mold in real time. The press-fitting driving device 59 can be realized by electric cylinders, air cylinders, motors with screw transmission, etc., and the present embodiment is illustrated by an air cylinder.

[0033] The annular press-fit seat 5 of this embodiment includes a press-fit fixing ring 51 which is vertically slidably mounted on the top frame 1 and is arranged outside the belt support seat 11. This embodiment shows that the press-fit fixing ring 51 is slidably mounted on the top frame 1 through four press-fit slide bars 52, and the top frame 1 is provided with press-fit sliding sleeves corresponding to the press-fit slide bars 52. The press-fit fixing ring 51 is radially slidably mounted with a belt pressing seat 53 corresponding to the belt pressing block 6, and each belt pressing seat 53 is respectively fixedly mounted with a corresponding belt pressing block 6; the belt pressing seat 53 is fixedly provided with a belt pressing position positioning pin 54, and the press-fit fixing ring 51 is provided with a belt pressing position adjusting ring 55 which can rotate along the circumference of the press-fit fixing ring 51, and the belt pressing position adjusting ring 55 is provided with a belt pressing position adjusting inclined hole 56 corresponding to the belt pressing position positioning pin 54, and a rotation guide device and a positioning fixing device are provided between the belt pressing position adjusting ring 55 and the press-fit fixing ring 51.

[0034] When the belt press position adjustment ring 55 described in the present embodiment rotates, the pressing force of the hole wall of the belt press position adjustment inclined hole 56 on the belt press position positioning pin 54 can generate a component force driving the belt press position positioning pin 54 along the radial direction of the press-fitting fixing ring 51. This component force can cause the belt press seat 53 to be displaced in the radial direction of the press-fitting fixing ring 51, so that the belt press block 6 can cooperate with the different unfolding positions of the belt support block 2 to adaptively adjust the belt press position, thereby achieving the effect of press-fitting belts 7 of different lengths, thereby broadening the scope of use of the present embodiment.

[0035] The rotation guide device can ensure the stability of the belt pressure position adjustment ring 55 during rotation adjustment. The rotation guide device of this embodiment includes at least three rotation guide rods fixedly arranged on the press-fit fixing ring 51, and the belt pressure position adjustment ring 55 is provided with rotation guide arc holes 57 corresponding to the rotation guide rods one by one. Of course, it is also possible to set arc holes on the press-fit fixing ring 51 and guide rods on the belt pressure position adjustment ring 55. There are four rotation guide rods in this embodiment. Since the press-fit fixing ring 51 of this embodiment is slidably installed through four press-fit slide rods 52, the press-fit slide rods 52 of this embodiment also serve as the rotation guide rods, which can also help simplify the overall structure of this embodiment and make the structure of this embodiment more compact.

[0036] The positioning and fixing device of this embodiment includes an adjusting ring stop 58 fixedly arranged on the belt pressing position positioning pin 54, and the belt pressing position positioning pin 54 is threadedly installed on the belt pressing seat 53. Furthermore, the belt pressing seat 53 of this embodiment is located below the press-fitting fixing ring 51 and is slidably installed through a slide groove, and the belt pressing position adjusting ring 55 is located above the press-fitting fixing ring 51, and the press-fitting fixing ring 51 is provided with a positioning pin avoidance long hole corresponding to the belt pressing position positioning pin 54, and the belt pressing position positioning pin 54 passes through the positioning pin avoidance long hole and the end of the belt pressing position adjusting inclined hole 56 to fix the adjusting ring stop 58. Such a setting of the belt pressing position positioning pin 54 can fix the belt pressing seat 53 below and the belt pressing position adjusting ring 55 above, and the structure is simple and reliable. When the belt pressing position needs to be adjusted, it is only necessary to loosen the belt pressing position positioning pin 54 appropriately so that the belt pressing position adjusting ring 55 can be rotated. Preferably, an adjustment operating rod is installed on the belt pressure position adjustment ring 55.

[0037] This embodiment shows that there are also eight belt pressing blocks 6, and the eight belt pressing blocks 6 are evenly distributed along the circumference of the annular belt pressing seat 53. Preferably, the belt pressing blocks 6 of this embodiment are arranged in an arc shape, which can better press down the belt 7 that is supported in a nearly circular shape. Preferably, a belt pressing inclined surface 61 is provided at the bottom of the belt pressing block 6. For the belt 7 whose cross section is mostly V-shaped, the arrangement of the belt pressing inclined surface 61 can evenly apply force to the inclined surface of the belt 7 to press down, prevent the belt 7 from twisting during the pressing process, and ensure the quality of the press-fitting.

[0038] In actual use of this embodiment, the connection structure of the top frame 1 can be specifically set according to the settings of the belt-incoming station and the vulcanizing station. If the belt-incoming station and the vulcanizing station are both fixed stations, the top frame 1 should be connected to a lifting mechanism and a position-changing translation mechanism. After the belt-incoming station props up the belt 7, it is translated to the vulcanizing station for press-fitting; if the belt-incoming station and the vulcanizing station are both movable to be set below the top frame 1, the top frame 1 only needs to be connected to a lifting mechanism. When the belt-incoming station arrives below the frame, the belt 7 is propped up, and when the belt-incoming station moves away and the vulcanizing station arrives below the top frame 1, press-fitting is performed. This embodiment is described in the following manner on the assumption that the belt-incoming station and the vulcanizing station are both fixed stations.

[0039] Initially, the support belt block 2 is in a retracted state. Figure 1 and Figure 2As shown. The top frame 1 is above the belt-incoming station, and the top frame 1 is driven down until the belt support block 2 is located within the belt 7 circle and stops. The belt support control motor 44 drives the belt support control screw 43 to rotate forward, and the belt support drive seat 41 descends until the support block position sensor 47 reaches the support block unfolding sensor 45, and the belt support control motor 44 stops. At this time, the belt support blocks 2 support the belt 7 into an approximately circular shape, as shown in FIG. Figure 3 and Figure 4 Then the top frame 1 is driven to rise and translate to above the vulcanization station, and the top frame 1 is driven to descend until the belt 7 stops at the circular mold. The press-fitting drive device 59 drives the annular press-fitting seat 5 to descend, as shown. Figure 5 As shown, the belt pressing block 6 presses the supported belt 7 into the circular mold. The annular press-fitting seat 5, the belt supporting block 2, etc. return to their original positions, and the top frame 1 is translated to the belt-incoming station to support the next belt 7. This operation is repeated until a specified number of belts 7 are pressed into the circular mold.

[0040] This embodiment realizes the automatic belt loading operation of the round mold vulcanization, reduces the labor intensity, reduces the labor cost, and is conducive to improving the overall efficiency of the production line. The working process only needs to be equipped with personnel for guarding or inspection, etc., and no close operation is required, which improves the working environment.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
