Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire production equipment, and more specifically to a foldable material roll guide device. Background Technology
[0002] As is well known, in the tire manufacturing industry, some products in the radial tire series for engineering machinery have gradually shifted from low-speed heavy-duty to high-speed, durable heavy-duty. This requires adjustments and optimizations to the product structure. Due to the insufficient functionality of the original molding machine, the newly added parts cannot be fed onto the original feeding rack. They need to be cut to a certain length from a separate material cart each time and then manually bonded, which poses certain quality risks. If a fixed station is added to the original feeding rack, the large width of the feeding rack will make production inconvenient when producing low-speed heavy-duty series, affecting production efficiency and posing certain safety hazards. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a foldable material roll opening device, which solves the problem that manual materials need to be cut to a certain length and then manually pasted on another material cart each time, which poses certain quality risks. It also solves the problem that the wide feed rack causes inconvenience in the production of low-speed heavy-duty series, which affects production efficiency and poses certain safety risks.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a foldable material roll guiding device, which is provided with a feeding rack support, and symmetrical square bar support brackets are provided on both sides of the feeding rack support, and respectively equipped with a brake-equipped guiding square bar support and a guiding square bar support. A guiding square bar is installed between the brake-equipped guiding square bar support and the guiding square bar support. Material guiding brackets and material guiding rollers are respectively installed on the upper and middle parts of the feeding rack support. The feature is that two sets of foldable material roll guiding devices are symmetrically installed on both sides of the upper part of the feeding rack support. One side of the foldable guiding double ear support of the foldable material roll guiding device is connected to the feeding rack support. The double ear side of the foldable guiding double ear support is hinged to the foldable guiding single ear support through a rotating pin. The foldable guiding single ear support is fixedly connected to the rotating square bar through a square bar bearing fixing seat. Adjustment is performed... The bolts connect the brake disc clearance adjustment spring, square bar bearing fixing seat, square bar rotating bearing, brake fixing disc two, splined brake disc, brake disc spline sleeve, brake fixing disc one to the plane of the folding guide single ear support. The rotating square bar is supported and connected to the square bar bearing fixing seat through the square bar rotating bearing. The surface of the rotating square bar near the shaft end is hinged with a roller positioning anti-disengagement stop. A set of horizontal positioning pins is inserted between the folding guide double ear support and the folding guide single ear support. The splined brake disc is connected to the rotating square bar through the brake disc spline sleeve. The splined brake disc is located between brake fixing disc one and brake fixing disc two. The splined brake disc drives the splined brake disc to perform friction braking with brake fixing disc one and brake fixing disc two through the brake disc spline sleeve. The brake disc clearance adjustment spring is compressed on the outside of brake fixing disc one and brake fixing disc two through the brake device adjustment fastening bolts.
[0005] The beneficial effects of this utility model are that when producing a large number of high-speed, durable, heavy-duty tire series components, they can be unfolded, fixed, and locked for feeding. When producing a small number of low-speed, heavy-duty tire series components, the fixing and locking pins can be opened, and the components can be folded down and stored, thus meeting the production process requirements and eliminating potential safety and quality hazards.

[0013] In the figure, the present invention has symmetrical square bar support brackets 2 on both sides of the feeding rack bracket 1, and is equipped with a brake-guided square bar seat 3 and a guide square bar seat 4 respectively. The brake-guided square bar seat 3 and the guide square bar seat 4 use the guide square bar 5 to suspend and store materials L1, L2, L3, L4, L5, L6, and L7 on the long roll 6 respectively. The materials are then guided to the operator's position in front of the machine by the material guide roller 9 and the material guide bracket 8. The short roll 7 is used to wind up materials L8, L9, L10, and L11 and is equipped with a foldable material roll guide device. On both sides of the upper part of the feeding rack support 1, two sets of foldable material roll guiding devices are symmetrically installed. One side of the plane of the foldable guiding double ear support Z1 is connected to the feeding rack support 1, and the double ear side is connected to the foldable guiding single ear support Z2 through the rotating pin Z3. The foldable material roll guiding device is equipped with an adjustable guiding brake device. The brake disc gap adjusting spring Z9, square bar bearing fixing seat Z8, square bar rotating bearing Z11, brake fixing disc two Z7, spline brake disc Z5, brake disc spline sleeve Z6, brake fixing disc one Z4 are connected to the plane of the foldable guiding single ear support Z2 through the brake device adjusting fastening bolt Z10. The rotating square bar Z12 is supported and connected to the square bar bearing fixing seat Z8 through the square bar rotating bearing Z11. The surface of the rotating square bar Z12 near the shaft head is equipped with a roll positioning anti-detachment stop Z13. The foldable guiding double ear support Z1 and the foldable guiding single ear support Z2 are each equipped with a set of horizontal positioning pins Z14.
[0014] The splined brake disc Z5 is connected to the rotating square bar Z12 via the brake disc spline sleeve Z6, so that when the square bar rotates, the brake disc spline sleeve Z6 drives the splined brake disc Z5 to perform friction braking with the brake fixing disc one Z4 and the brake fixing disc two Z7.
[0015] The gap between the splined brake disc Z5 and the brake mounting discs Z4 and Z7 is adjusted by compressing the brake disc gap adjusting spring Z9 by adjusting the fastening bolt Z10 of the brake device.
[0016] The rotating square bar Z12 has a roll positioning anti-detachment stop Z13 near the shaft head surface. After the material roll of the short roll 7 is installed in place, the roll positioning anti-detachment stop Z13 is lifted to prevent detachment. When the material roll is used up and needs to be replaced, the roll positioning anti-detachment stop Z13 is flipped into the rotating square bar Z12, lower than the upper plane of the rotating square bar Z12, so that the short roll 7 can be taken out easily.
[0017] In addition to rotating at 90° via the rotating pin Z3, the folding open double-ear support Z1 and the folding open single-ear support Z2 are also equipped with a separate horizontal positioning pin Z14. The horizontal positioning pin Z14 is used to lock the supports and prevent them from sagging. After use, the horizontal positioning pin Z14 is removed, and the folding open double-ear support Z1 and the folding open single-ear support Z2 are folded at 90° to a vertical position. The horizontal positioning pin Z14 is then locked to prevent them from being opened manually.
[0018] The specific adjustment operation is as follows: The operator takes the materials L1 (1#), L2 (2#), L3 (3#), L4 (4#), L5 (5#), L6 (6#), and L7 (7#) wound by the long roll 6 and places them on the symmetrical square bar seat brackets 2 on both sides of the feeding rack bracket 1 using guide bars 5. The square bar seat brackets 2 are equipped with guide bar seats 3 and 4 with brakes. The guide bar seats 3 with brakes are adjusted to a reasonable tightness to prevent the material roll from uncontrolled falling and causing sticking or stretching. The materials L1 (1#), L2 (2#), L3 (3#), L4 (4#), L5 (5#), L6 (6#), and L7 (7#) are guided through the material guide brackets 8 and material guide rollers 9 to the front end of the feeding rack bracket 1 for easy material handling during production. When there are insufficient guide positions, open the horizontal positioning pins Z14 on the folding guide double-ear support Z1 and the folding guide single-ear support Z2 as needed. Open the foldable material roll guide devices symmetrically mounted on both sides of the upper part of the feed rack bracket 1 with the rotating pin Z3 as the axis. After the rotating square bar Z12 is in a horizontal position, lock the horizontal positioning pins Z14 on the folding guide double-ear support Z1 and the folding guide single-ear support Z2. Flip the roll positioning anti-detachment stop Z13 into the guide square bar 5. Place the material rolls 8# material L8, 9# material L9, 10# material L10, and 11# material L11 wound by the short roll 7 onto the rotating square bar Z12. Flip the roll positioning anti-detachment stop Z13 out of the square bar, higher than the square bar size, to stop and prevent the material roll from falling off. Pull the 8# material L11... Materials L9 (8# and 9#), L10 (10#), and L11 (11#) are driven by short reel 6 to rotate square bar Z12. While the square bar rotates with the support of rotating bearing Z11, the spline sleeve Z6 at the end of the rotating square bar Z12 rotates synchronously. This causes the spline brake disc Z5 to rub against brake fixing discs Z7 and Z4 (fixed to the square bar bearing fixing seat Z8 by adjusting the fastening bolt Z10 and the brake disc gap adjusting spring Z9), generating resistance and preventing the material roll from being uncontrolled. To prevent the brake gap from being too small or too large, the gap between spline brake disc Z5, brake fixing disc Z7, and brake fixing disc Z4 can be adjusted by adjusting the distance between the fastening bolt Z10 and the brake disc gap adjusting spring Z9 to meet the process standard dimensions and prevent stretching or material accumulation. After use, when there is sufficient space in the guide opening position, open the horizontal positioning pin Z14 provided on the foldable guide double ear support Z1 and the foldable guide single ear support Z2, so that the foldable material roll guide opening device is folded vertically with the rotating pin Z3 as the axis, and the horizontal positioning pin Z14 is locked to increase the on-site operating space.It effectively solves the problem that manual bonding requires each person to manually cut a certain length from a separate material cart for each batch, which poses certain quality risks. It also solves the problem that adding a fixed station to the existing material feeder would be inconvenient and affect production efficiency and pose certain safety hazards when producing low-speed heavy-duty series products due to the large width of the material feeder.
