Description

Technical Field

[0001] The utility model relates to the field of tire preparation, in particular to a preparation device for an anti-skid tire. Background Art

[0002] Polyurethane tires are widely used in heavy-duty handling equipment such as forklifts due to their excellent wear resistance, cut resistance, oil resistance and chemical stability. However, on slippery or greasy roads, the friction coefficient of traditional polyurethane tires is low, and they are prone to slipping, increasing the risk of driving. Therefore, the development of polyurethane tires with enhanced anti-skid properties is crucial to improving the safety and work efficiency of special vehicles such as forklifts. In addition, the current preparation of anti-skid tires is done by people guiding the injection head to inject material into the mold, and then manually closing the mold and centrifugal molding, which has low production efficiency. Utility Model Content

[0003] In order to solve the problem of low production efficiency of existing anti-skid tires, the utility model provides a preparation device for anti-skid tires, which improves the production efficiency of tires by improving the equipment structure.

[0004] The utility model provides a preparation device for an anti-skid tire, comprising a material molding mechanism for material casting and molding, a material injection mechanism for injecting material into a mold, a clamping mechanism for demolding the anti-skid tire, and a conveying mechanism for conveying the anti-skid tire; the material molding mechanism is provided with a plurality of them, each of which comprises a rotating disk, the rotating disk is connected to a rotary drive mechanism, a mold is fixed on the rotating disk, the mold comprises a lower mold and an upper mold, one end of the upper mold is hingedly connected to the lower mold, and the material molding mechanism also comprises an opening and closing drive mechanism for controlling the opening and closing of the upper mold and the lower mold.

[0005] Through the above technical solution, by integrating the rotating disk and the rotary drive mechanism in the material molding mechanism, the automatic rotation of the mold is realized, which not only simplifies the operation process, but also improves the uniformity and consistency of the material pouring process, thereby improving the quality of the finished tire and the production efficiency.

[0006] As a preferred embodiment of the utility model, locking blocks are provided on the upper mold and the lower mold, and a socket is provided on the locking block; a locking drive mechanism for locking the upper mold and the lower mold is also provided on the rotating disk, and the locking drive mechanism includes a pin and a driving member for driving the pin to be inserted into the socket.

[0007] Through the above technical solution, locking blocks and sockets are arranged on the upper mold and the lower mold, and a locking drive mechanism with a tapered pin is adopted to ensure the sealing and stability of the mold when it is closed, effectively avoiding material leakage during the pouring process, while improving the reuse accuracy of the mold and extending the service life of the mold.

[0008] As a preferred embodiment of the present invention, the insertion pin is a conical structure, and the diameter of the insertion pin on a side close to the locking block is smaller than the diameter of the insertion pin on a side away from the locking block.

[0009] Through the above technical solution, the design of the tapered pin can automatically correct the alignment even when there is a slight misalignment of the mold locking block, ensuring the reliable closure of the mold, reducing the production of defective products due to incomplete mold closure, and improving the product qualification rate.

[0010] As a preferred embodiment of the present invention, the material forming mechanism is distributed in a straight line, the injection mechanism is distributed on one side of the material forming mechanism in the width direction, the clamping mechanism and the conveying mechanism are distributed on the other side of the material forming mechanism in the width direction, and the conveying mechanism is arranged between the material forming mechanism and the clamping mechanism.

[0011] Through the above technical solution, the linear distribution of the material forming mechanism and the reasonable layout of the injection, clamping and conveying mechanisms optimize the space utilization of the production line, simplify the flow path of materials and products, and significantly improve production efficiency and operation fluency.

[0012] As a preferred embodiment of the utility model, the clamping mechanism includes a mechanical arm and a clamping head connected to the mechanical arm, the clamping head includes a clamping top plate and a supporting top rod arranged on the back of the clamping top plate, the supporting top rod is connected to the supporting cylinder, and four supporting top rods are arranged and distributed in a cross.

[0013] Through the above technical solution, the clamping mechanism adopts a mechanical arm with a clamping head with a cross-distributed support push rod, which not only improves the flexibility and accuracy of the demolding operation, but also ensures the stability and safety of the demolding process, reduces damage to the tire, and improves the appearance quality of the finished product.

[0014] As a preferred embodiment of the present invention, an arc-shaped guide portion is provided on a side of the supporting top rod away from the clamping top plate.

[0015] Through the above technical solution, an arc-shaped guide portion is added to the side of the support push rod away from the clamping top plate, which helps to guide the support push rod to smoothly enter the inner ring of the tire, ensure the smooth progress of the demolding process, reduce operating resistance, reduce energy consumption, and at the same time improve the efficiency and success rate of the demolding operation.

[0016] As a preferred embodiment of the present invention, a vacuum suction cup is further provided on the back side of the clamping top plate, and the vacuum suction cup is distributed on the outer side of the supporting top rod.

[0017] Through the above technical solution, the vacuum suction cups configured on the back of the clamping top plate are distributed on the outside of the supporting top rod. This design innovatively utilizes the vacuum adsorption force and significantly enhances the gripping force and stability during the tire demoulding process. The vacuum suction cups can effectively adsorb the inner surface of the tire, ensuring smooth and damage-free demoulding even in complex or delicate tire structures, greatly improving demoulding efficiency and reducing product damage rate, ensuring the integrity and quality of tire products, and further improving the automation level and production efficiency of the entire preparation device.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. The utility model significantly improves the automation level and production efficiency of tire production by designing an efficient anti-skid tire preparation device. The device integrates multiple key functional modules such as material casting and molding, injection, clamping and conveying, forming a highly integrated production line. In particular, the multi-point layout and rotating disk design of the material molding mechanism, combined with the rotary drive mechanism, realize the rapid switching and precise positioning of the mold, which can not only meet the production needs of tires of different specifications, but also greatly shorten the mold replacement time and improve the versatility and flexibility of the equipment. In addition, the introduction of the opening and closing drive mechanism makes the automatic opening and closing process of the mold faster and more accurate, avoiding the inefficiency and uneven quality caused by manual intervention, and significantly improving the molding efficiency and consistency of product quality.

[0020] 2. The locking mechanism of the utility model realizes reliable closure of the mold by setting locking blocks and jacks on the upper mold and the lower mold, and using the locking drive mechanism of the tapered pin. The design of the tapered pin is particularly ingenious. Even if the mold may have a slight displacement after long-term use, the adaptive adjustment function of the tapered pin can ensure a close fit between the molds, thereby effectively solving the problem of poor fit caused by wear or deformation of traditional molds, and significantly improving the service life of the mold and the accuracy of tire molding. The application of this locking mechanism not only reduces material waste, but also ensures the continuity and stability of the production process, further improving the overall production efficiency.

[0021] 3. The layout of the clamping mechanism and conveying mechanism of the utility model is reasonable, and the continuity of the production process is fully considered. The clamping mechanism adopts a mechanical arm with a cross-distributed support top rod design, and cooperates with the intelligently controlled support cylinder, so that the demoulding process is both accurate and efficient, reducing physical damage to the tire and ensuring the integrity and surface quality of the tire. In particular, the vacuum suction cup arranged on the back of the clamping top plate cleverly uses vacuum adsorption technology to further strengthen the firm grip of the tire, ensure the smooth transition of the tire during the demoulding process, avoid jamming or falling off during the demoulding stage, and greatly improve the success rate and efficiency of demoulding. This intelligent and automated design concept significantly reduces labor costs, improves production safety and economic benefits, and provides strong support for achieving the goals of high efficiency and high quality in tire manufacturing.

DETAILED DESCRIPTION

[0027] The following will be combined with the following embodiments of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figures 1 to 4This embodiment discloses a device for preparing an anti-skid tire, including a material molding mechanism 1 for casting and molding materials, an injection mechanism 2 for injecting materials into a mold, a clamping mechanism 3 for demolding the anti-skid tire, and a conveying mechanism 4 for conveying the anti-skid tire.

[0029] There are multiple material forming mechanisms 1, and the multiple material forming mechanisms 1 are distributed in a straight line. In this embodiment, each material forming mechanism 1 includes a frame 11, and a rotating disk 12 is arranged on the frame 11. The rotating disk 12 is connected to a rotary drive mechanism. In this embodiment, the rotary drive mechanism is arranged below the rotating disk 12, and the rotary drive mechanism is used to drive the rotating disk 12 to rotate. In this embodiment, the rotary drive mechanism can be a motor connected to the rotating disk 12 through a gear, or a motor driving the rotating disk 12 through a sprocket or a chain, or a motor driving the rotating disk 12 to rotate through a belt.

[0030] A mold is fixed on the rotating disk 12, and the mold is fixed to the rotating disk 12 by bolts. In this way, molds of different specifications can be replaced on the rotating disk 12, so as to produce tires of different specifications.

[0031] In this embodiment, the mold includes a lower mold 13 and an upper mold 14, and one end of the upper mold 14 is hingedly connected to the lower mold 13, so that the upper mold 14 and the lower mold 13 can be opened and closed. When the upper mold 14 is opened, the upper mold 14 is separated from the lower mold 13, and then the material can be injected into the mold cavity of the lower mold 13. When the upper mold 14 and the lower mold 13 are closed, a cavity for molding a tire is formed between the upper mold 14 and the lower mold 13. In the present embodiment, the opening and closing between the upper mold 14 and the lower mold 13 is automatic. Specifically, an opening and closing driving mechanism for controlling the opening and closing of the upper mold and the lower mold is arranged on the rotating disk 12. In the present embodiment, the opening and closing driving mechanism includes two opening and closing driving cylinders 15. One end of the opening and closing driving cylinder 15 is hinged to the rotating disk 12, and the other end is hinged to the upper mold 14. When the opening and closing driving cylinder 15 is lifted, one end of the upper mold 14 is driven to be lifted, thereby opening the upper mold 14 and the lower mold 13; when the opening and closing driving cylinder 15 is contracted, one end of the upper mold 14 is driven to descend, thereby closing the upper mold 14 and the lower mold 13.

[0032] After the upper mold 14 and the lower mold 13 are molded together, the rotating disk 12 rotates to drive the material in the mold cavity to be centrifugally molded. In order to ensure that the upper mold 14 and the lower mold 13 are tightly molded, in this embodiment, locking blocks are provided on the upper mold 14 and the lower mold 13, specifically: an upper locking block 16 is provided on the upper mold 14, and a lower locking block 17 is provided on the lower mold 13. Plug holes 19 are provided on the upper locking block 16 and the lower locking block 17; when the upper mold 14 and the lower mold 13 are molded together, the upper locking block 16 corresponds to the plug holes 19 on the lower locking block 17. A locking drive mechanism for locking the upper mold 14 and the lower mold 13 is also provided on the rotating disk 12. In the present embodiment, the locking drive mechanism adopts a locking cylinder 18, and a pin is connected to one end of the locking cylinder 18. When the upper mold 14 and the lower mold 13 are closed, the locking cylinder 18 drives the pin to be inserted into the socket 19 on the upper locking block 16 and the lower locking block 17, thereby locking the upper mold 14 and the lower mold 13.

[0033] In actual use, as time goes by, the opening and closing driving cylinder 15 cannot accurately close the upper mold 14 and the lower mold 13 when driving them to close. At this time, the insertion holes 19 on the upper locking block 16 and the lower locking block 17 cannot be accurately aligned. In order to solve this problem, in this embodiment, the insertion pin is set as a conical structure, and the diameter of the insertion pin close to the locking block is smaller than the diameter of the insertion pin away from the locking block. At this time, if there is a partial deviation between the insertion holes 19 on the upper locking block 16 and the lower locking block 17, the insertion pin action can drive the upper mold 14 and the lower mold 13 to close in place, thereby ensuring the quality of the product.

[0034] The injection mechanism 2 is distributed on one side of the width direction of the material forming mechanism 1. The injection mechanism 2 includes an injection head and an injection frame. The injection head is connected to a material storage box through a pipeline. The injection head can move in the up and down, front and back (one side of the width direction of the material forming mechanism 1) directions on the injection frame. A walking drive mechanism is provided at the bottom of the injection frame, which can move on the injection mechanism guide rail. The injection mechanism guide rail is distributed along the length direction (left and right) of the material forming mechanism 1, so that the injection head can be driven to move along the length direction of the material forming mechanism 1 to inject material into the mold of each material forming mechanism 1.

[0035] The clamping mechanism 3 and the conveying mechanism 4 are distributed on the other side of the material forming mechanism 1 in the width direction (front-back direction), and the conveying mechanism 4 is arranged between the material forming mechanism 1 and the clamping mechanism 3. The conveying mechanism 4 is a belt conveyor, and the material transmission direction of the belt conveyor is along the length direction (left-right direction) of the material forming mechanism 1. The conveying mechanism 4 is used to transfer and convey the product after demolding from the mold.

[0036] In this embodiment, the clamping mechanism 3 includes a mechanical arm 32 and a clamping head connected to the mechanical arm 32. One end of the mechanical arm 32 is connected to a movable base 33. The movable base 33 is arranged on a clamping mechanism guide rail 6. The movable base 33 can move on the clamping mechanism guide rail 6. The clamping mechanism guide rail 6 is distributed along the length direction (left and right) of the material forming mechanism 1, thereby driving the clamping mechanism 3 to move along the length direction of the material forming mechanism 1 to demold and unload each material forming mechanism 1.

[0037] In this embodiment, the clamping head includes a clamping top plate 31 and a support top rod 35 arranged on the back of the clamping top plate 31. The support top rod 35 is connected to the support cylinder 34. In this embodiment, four support top rods 35 are arranged in a cross distribution. An arc-shaped guide portion 36 is arranged on the side of the support top rod 35 away from the clamping top plate 31. The arc-shaped guide portion 36 facilitates the insertion of the support top rod 35 into the inner ring of the tire, and then the support cylinder 34 is actuated to clamp the support top rod 35 and the inner ring of the tire tightly, which facilitates demoulding.

[0038] In order to further facilitate demoulding, a vacuum suction cup (not shown) is further provided on the back of the clamping top plate 31, and the vacuum suction cup is distributed on the outside of the supporting top rod 35. In this way, the tire is more easily demoulded from the mold through the combined action of the vacuum suction cup and the supporting top rod 35.

[0039] The above are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model patent. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
