Description

Technical Field

[0001] The utility model relates to a guiding and correcting mechanism for grabbing a triangle rubber material. Background Art

[0002] The bead of the tire is usually composed of a wire ring, a triangular rubber strip, a bead cover, etc. The triangular rubber strip plays a filling role in the bead to fill the dead corner formed by the bead part to avoid the place being pressed unsolidly and hiding air.

[0003] Loading the apex rubber onto the outer ring of the bonding drum includes the following specific working process: the cut apex rubber is transported to the discharge port by a conveyor belt, the apex rubber head is adsorbed and placed on the forming drum by an adsorption device, the rotary driving power transmitted from the main shaft of the forming drum actuates the forming drum to rotate, and drives the apex rubber to be wound around the drum, after the forming drum rotates one circle, the apex rubber head end is placed on the drum by an adsorption device, so that the head and tail of the material overlap to form a cylindrical apex rubber ring, and then further processed to obtain the apex rubber tire bead product.

[0004] like Figure 7 As shown, since the apex rubber is a flexible structure, during the cutting process, the head end of the formed apex rubber material will deviate from the predetermined conveying route driven by the cutter, which will cause the head end of the material to fit the drum incorrectly, and after the forming drum rotates one circle, the head and the tail of the material cannot be accurately overlapped together, so that the produced apex rubber material ring has poor flatness and loose joints, resulting in low yield or even unqualified apex rubber tire bead products, which is not conducive to mass production. Utility Model Content

[0005] The utility model provides a guiding and correcting mechanism for grabbing a triangular rubber material, which can effectively solve the above-mentioned problem.

[0006] The utility model is achieved in this way:

[0007] A guiding and correcting mechanism for grabbing apex rubber material, comprising a conveyor belt structure for conveying apex rubber to a forming drum, and a cutter structure installed at a material outlet of the conveyor belt structure; the characteristic is that it also comprises a guiding and correcting mechanism, wherein the guiding and correcting mechanism is a material outlet guide installed at the front end of the cutter structure;

[0008] The apex rubber conveyed by the conveyor has a conveying bottom surface z, a long surface x and a short surface y, which are in descending order of length, and the conveying bottom surface z and the long surface x form a chamfered portion, and the discharge guide comprises a push block which is slidably arranged at the discharge port of the conveyor structure and aligned with the chamfered portion;

[0009] When the cutting knife structure cuts out the head end of the apex rubber and conveys it to the discharge port, the pushing block slides and pushes the corner portion to align the head end of the apex rubber to the predetermined conveying path.

[0010] As a further improvement, the discharge guide also includes a push cylinder fixedly mounted at the discharge port of the conveyor belt, the piston rod of the push cylinder is fixedly connected to the push block, and the sliding direction of the push block is perpendicular to the predetermined conveying path of the apex rubber.

[0011] As a further improvement, the push block is provided with an actuating avoidance groove for aligning the guide angle portion, and the actuating avoidance groove is formed by an arc-shaped avoidance surface and a groove wall surface; when the push block pushes the guide angle portion, the arc-shaped avoidance surface slides away the guide angle portion to align the apex rubber to the predetermined conveying path.

[0012] The beneficial effects of the utility model are:

[0013] The present application arranges the material discharge guide at the front end of the cutting knife structure. After cutting is completed, the material discharge guide can also push the head end of the apex rubber to the predetermined conveying path to ensure that the head end and the tail end of the apex rubber can be accurately overlapped on the forming drum, which greatly improves the flatness of the apex rubber material ring and the yield rate of the apex rubber tire bead products.

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] like Figure 1 to Figure 5 and Figure 7 As shown, a continuous laminating film conveyor with a positioning device comprises a conveyor belt structure 10 for conveying apex rubber 50 to a forming drum 70, a cutter structure 20 installed at a discharge port 102 of the conveyor belt structure 10, and a positioning device 30, wherein the positioning device 30 comprises a feed guide 31 installed at a feed port 101 of the conveyor belt structure 10, a discharge guide 32 installed at the front end of the cutter structure 20, and a surface pressure guide assembly 33 installed at the middle of the conveyor belt structure 10; the apex rubber 50 conveyed by the conveyor 60 has a conveying bottom surface z, a long surface x, and a short surface y, which are conveyed by the laminating conveyor belt structure 10 in descending order in length, and the conveying bottom surface z and the long surface x are spaced apart. The chamfered portion 51 is formed, and the discharge guide 32 includes a push block 322 which is slidably arranged at the conveyor belt discharge port 102 and aligned with the chamfered portion 51; the feed guide 31 limits the two ends of the conveying bottom surface z of the apex 50, so that the apex 50 enters the conveyor belt structure 10 in a posture aligned with the predetermined conveying path, and the surface pressure-conducting component 33 continuously presses the long surface x and a short surface y of the apex 50, so that the apex 50 is conveyed on the conveyor belt structure 10 along the predetermined conveying path; when the cutting knife structure 20 cuts out the head end 501 of the apex 50 and conveys it to the discharge port 102, the push block 322 slides and pushes the chamfered portion 51, so that the head end 501 of the apex 50 is aligned to the predetermined conveying path.

[0036] It should be noted here that since the apex glue 50 is a flexible structure, after the cutting structure 20 completes the cutting, the head end 501 of the next round of apex glue 50 formed by the cutting will be driven by the cutting structure 20 (the tail end 502 of the apex glue 50 that is initially drum-bonded is formed synchronously during the cutting process) and positioned to deviate from the predetermined conveying path. The present application adds a discharge guide 32 at the front end of the cutting structure 20 to align the head end 501 of the apex glue 50 to the predetermined conveying path, so that the head end 501 and the tail end 502 of the apex glue 50 are in the predetermined conveying path throughout the entire conveying process, which greatly improves the flatness of the processed apex glue 50 material ring and the yield rate of the subsequently processed apex glue 50 circles.

[0037] The structures of the various components of the utility model are described below.

[0038] like Figure 1 , Figure 2 and Figure 4 , Figure 5 As shown, the discharge guide member 32 also includes a push cylinder 321 fixedly mounted at the conveyor belt discharge port 102, the piston rod of the push cylinder 321 is fixedly connected to the push block 322, and the sliding direction of the push block 322 is perpendicular to the predetermined conveying path of the apex rubber 50; the push block 322 is provided with an actuating avoidance groove 3221 for aligning the guide angle portion 51, and the actuating avoidance groove 3221 is surrounded by an arc-shaped avoidance surface 32211 and a groove wall surface 32212; when the push block 322 pushes the guide angle portion 51, the arc-shaped avoidance surface 32211 slides away the guide angle portion 51, so that the apex rubber 50 is aligned to the predetermined conveying path, and there is a clearance gap between the guide angle portion 51 and the actuating avoidance groove 3221, so as to avoid curling of the guide angle portion 51 of the apex rubber 50.

[0039] like Figure 1 to Figure 3 The feed guide 31 includes at least one guide rod group 311 rotatably arranged at the feed port 101 of the conveyor belt structure 10, and the guide rod group 311 includes two guide rods 3111 arranged at intervals, and the interval between the two guide rods 3111 is equal to the length of the conveying bottom surface z of the apex 50; in this embodiment, two sets of guide rod groups 311 arranged side by side are taken as an example. When feeding the conveyor 60, the conveying bottom surface z of the apex 50 is aligned with the two guide rods 3111 and fed into the conveyor belt structure 10, so that the apex 50 can enter the conveyor belt structure 10 in a posture aligned with the predetermined conveying path.

An angle α is formed between the rotation center axis of the climbing roller 12 and the left and right directions perpendicular to the predetermined conveying path (that is, an acute angle is formed between the rotation center axis of the climbing roller 12 and the right side plate 11), so that when the apex rubber 50 is conveyed, its short surface y has a tendency to move close to the short side guide wheel 3321, and the short surface y is maintained in a state of pressing against the short side guide wheel 3321, so as to further guide the apex rubber 50 to the predetermined conveying path.
