Description

Technical Field

[0001] This utility model relates to the field of tire production equipment technology, specifically to a gantry vulcanizing machine with a blow molding device. Background Technology

[0002] Currently, with the rapid development of China's automotive industry, the demand for tires is increasing. Tire production generally involves the following steps: raw material preparation – rubber refining and compounding – tread and carcass manufacturing – semi-finished product production – molding – vulcanization – quality inspection and packaging.

[0003] After assembling semi-finished products such as the tread, carcass, and cord fabric into a green tire (an uncured tire, also called a tire blank) on a forming machine, the formed green tire needs to be placed in a vulcanizing machine and vulcanized in a mold under appropriate time and conditions. Vulcanization is one of the key steps in tire production. It enables the rubber to bond tightly with the carcass to form the tire and improves its strength and wear resistance.

[0004] The green tire is placed in the vulcanizing chamber of the vulcanizing machine for vulcanization. During vulcanization, moisture in the green tire gradually separates, and water vapor condenses on the inner wall of the vulcanizing chamber, forming water droplets. After vulcanization, the upper vulcanizing chamber mold (i.e., the upper mold cavity) is lifted by a gantry crane, and the tire is moved away by a robotic arm. Workers then need to use handheld equipment to dry the moisture on the inner walls of the upper and lower vulcanizing chamber molds to prevent affecting the vulcanization of the next green tire. During the drying of the upper vulcanizing chamber mold, workers must stand directly below it, holding tools and looking upwards; this is not only extremely arduous and inefficient, but also carries the safety risk of the upper vulcanizing chamber mold accidentally falling and injuring workers.

[0005] Therefore, existing technologies need further development. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a gantry vulcanizing machine with a blow molding device to solve the technical problem of low drying efficiency of the upper vulcanizing chamber mold in related technologies.

[0007] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A gantry vulcanizing machine with a blow molding device is provided, characterized in that it includes: a vulcanizing chamber having an upper vulcanizing chamber mold and a lower vulcanizing chamber mold; a gantry frame, which is movably arranged along a preset direction, the gantry frame being used to grip the upper vulcanizing chamber mold, causing the upper vulcanizing chamber mold to move relative to the lower vulcanizing chamber mold; and a blow molding device, which is mounted on the gantry frame, the blow molding device including a blower, the blower's air outlet facing the inner cavity of the upper vulcanizing chamber mold, the blower's airflow direction having a certain angle with the horizontal direction, to dry the inner cavity of the upper vulcanizing chamber mold.

[0008] Furthermore, the gantry vulcanizing machine includes a fan mounting bracket, which is fixedly installed on the gantry frame and is used to support the fan. The fan is rotatably connected to the fan mounting bracket.

[0009] Furthermore, the fan mounting bracket includes a mounting base plate and fixing nuts. The mounting base plate has mounting holes. Connecting components are provided at both ends of the fan. The connecting components have external threads and are inserted into the mounting holes. The fixing nuts are threadedly connected to the connecting components and can abut against the mounting base plate. There are two mounting base plates, which are arranged opposite each other, and two fixing nuts are provided accordingly.

[0010] Furthermore, the wind turbine mounting frame includes mounting columns, which are spaced apart from the supports of the gantry frame, with the extension direction of the mounting columns parallel to the supports; one of the two mounting base plates is mounted on the support of the gantry frame, and the other of the two mounting base plates is mounted on the mounting column of the gantry frame.

[0011] Furthermore, the blower is movably mounted along the height direction of the blower mounting bracket to adjust the relative height between the blower and the upper vulcanizing chamber mold.

[0012] Furthermore, the mounting holes include multiple holes, which are spaced apart along the height direction of the fan mounting bracket.

[0013] Furthermore, the gantry vulcanizing machine includes a controller, which is connected to the blow molding device and the gantry frame respectively, so as to control the start of the blow molding device according to the mold opening action of the gantry frame.

[0014] Furthermore, the fan includes multiple fans, each of which is respectively installed corresponding to multiple support columns of the gantry frame.

[0015] Furthermore, the vulcanizing chambers include multiple vulcanizing chambers, which are spaced apart along a predetermined direction.

[0016] Furthermore, protective plates are installed on the sides of the gantry frame, with clearance openings on the protective plates to allow the fans to pass.

[0017] Beneficial effects:

[0018] 1. By installing a blower at the corresponding position on the gantry, the upper vulcanizing chamber mold can be automatically dried. The entire drying process can be completed automatically without manual intervention. The blower is directly installed on the gantry, so that the upper vulcanizing chamber mold can enter the blowing state immediately after vulcanization is completed without having to move it to a dedicated blowing station. This significantly improves the drying efficiency of the upper vulcanizing chamber mold and solves the technical problem of low drying efficiency of the upper vulcanizing chamber mold in related technologies.

[0019] 2. The upper vulcanizing chamber mold is hoisted to the mold opening position by a gantry frame. After the mold opening action is detected, the blower of the blow molding device is automatically turned on by the PLC programming control program to achieve automatic drying without manual operation, which greatly improves work efficiency and avoids safety hazards.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] As described in the background section, in the prior art, when drying the upper vulcanizing chamber mold, workers need to stand directly below the upper vulcanizing chamber mold 101, which makes the work extremely arduous and inefficient, and there is also a safety risk that the upper vulcanizing chamber mold 101 may accidentally fall and injure the workers.

[0033] In existing technology, the layout of a gantry vulcanizing machine is as follows: Figure 7 As shown, a gantry frame is usually provided for multiple vulcanizing chambers 10. One gantry frame realizes the function of controlling the opening and closing of multiple vulcanizing chambers, that is, the gantry frame 1 can move back and forth between station 1 201 and station 5 205.

[0034] If a blow molding station is added to station 206 at position 6 to solve the technical problems mentioned in the background section, after the mold is opened at station 1 at position 201, the gantry frame 1 needs to move with the vulcanizing chamber mold 101, traversing multiple stations to station 206 for blow molding. After blow molding is completed, it needs to return from station 206 to station 1 at position 201 to close the mold, so that the next vulcanizing process can begin. Similarly, other stations also need to traverse multiple stations to complete blow molding. This design results in each blow molding process requiring traversing multiple stations, and the gantry frame movement consumes too much time, severely impacting vulcanizing efficiency.

[0035] Therefore, based on the working principle of the gantry vulcanizing machine, the applicant made the following improvements to the gantry vulcanizing machine.

[0036] According to an embodiment of this utility model, a gantry vulcanizing machine with a blow molding device is provided. Please refer to [link / reference]. Figures 1 to 7 The device includes: a vulcanizing chamber 10 having an upper vulcanizing chamber mold 101 and a lower vulcanizing chamber mold; a gantry frame 1, which is movably arranged along a preset direction and is used to grip the upper vulcanizing chamber mold 101, causing the upper vulcanizing chamber mold 101 to move relative to the lower vulcanizing chamber mold; and a blow molding device, which is mounted on the gantry frame 1 and includes a blower 2, the blower 2 having its air outlet facing the inner cavity of the upper vulcanizing chamber mold 101, and the blower 2 having a certain angle with the horizontal direction to dry the inner cavity of the upper vulcanizing chamber mold 101.

[0037] Specifically, since the inner cavity of the upper vulcanizing chamber mold 101 has a shape and a certain depth, the air outlet of the blower 2 is directed toward the inner cavity of the upper vulcanizing chamber mold 101, and its blowing direction has a certain angle with the horizontal direction. By optimizing the air duct layout and air direction angle, it is ensured that the airflow can cover the entire inner cavity depth of the upper vulcanizing chamber mold 101, thereby quickly removing residual moisture or vulcanization products, effectively drying the inner cavity of the upper vulcanizing chamber mold, and significantly improving the drying efficiency.

[0038] With the above setup, a blower 2 is installed at the corresponding position of the gantry 1, which enables automatic drying of the upper vulcanizing chamber mold 101. The entire drying process can be completed automatically without manual intervention. By directly installing the blower 2 on the gantry 1, the upper vulcanizing chamber mold 101 can immediately enter the blow molding state after vulcanization without having to be moved to a dedicated blow molding station. This significantly improves the drying efficiency of the upper vulcanizing chamber mold and solves the technical problem of low drying efficiency of the upper vulcanizing chamber mold in related technologies.

[0039] It should be noted that, since the inner cavity of the upper vulcanizing chamber mold 101 has a shape and a certain depth, and during vulcanization, more moisture evaporates upwards, there is less residual moisture on the lower vulcanizing chamber mold. The gantry vulcanizing machine with blow molding device in this application is mainly used for air drying the upper vulcanizing chamber mold.

[0040] It is understood that the blow molding device in this embodiment can also be applied to the air drying process of the lower vulcanizing chamber mold or other types of vulcanizing machines, depending on actual needs.

[0041] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4 The gantry vulcanizing machine includes a fan mounting frame 3, which is fixedly mounted on the gantry frame 1. The fan mounting frame 3 supports the fan 2, and the fan 2 is rotatably connected to the fan mounting frame 3. Specifically, the fan mounting frame 3 is fixedly mounted on the gantry frame 1 to support the fan 2, ensuring that the fan will not shift or tilt due to vibration or other external forces during operation. The rotatable connection between the fan 2 and the fan mounting frame 3 allows the fan to be flexibly adjusted within a certain range. The airflow direction of the fan can be adjusted according to actual needs, ensuring that the airflow can cover the entire inner depth of the vulcanizing chamber mold 101, guaranteeing the drying effect.

[0042] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4-6The fan mounting bracket 3 includes a mounting base plate 31 and a fixing nut 32. The mounting base plate 31 has mounting holes 311. The fan 2 has connecting parts 21 at both ends. The connecting parts 21 have external threads and are inserted into the mounting holes 311. The fixing nuts 32 are threadedly connected to the connecting parts 21 and can abut against the mounting base plate 31. There are two mounting base plates 31, which are arranged opposite to each other, and there are two fixing nuts 32 accordingly.

[0043] In some embodiments, the fixing nuts 32 include two nuts, which are located on both sides of the mounting base plate 31.

[0044] In some embodiments, the connecting component 21 is a screw.

[0045] In this way, by passing the connecting part 21 of the fan 2 through the mounting hole 311 on the mounting base plate 31 and tightening it with two fixing nuts 32, the fan is secured by clamping the mounting base plate 31 with the two fixing nuts 32, ensuring that the fan will not shift or shake during operation. When the fan needs to be inspected or replaced, it can be easily disassembled by simply loosening the fixing nuts 32. Since the connecting part 21 and the fixing nuts 32 are connected by threads, the height and angle of the fan can be adjusted by rotating the fixing nuts, thus achieving flexible installation and commissioning.

[0046] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4 The fan mounting frame 3 includes mounting columns 33, which are spaced apart from the support columns 11 of the gantry frame 1. The extension direction of the mounting columns 33 is parallel to that of the support columns 11. One of the two mounting base plates 31 is mounted on the support column 11 of the gantry frame 1, and the other of the two mounting base plates 31 is mounted on the mounting column 33 of the gantry frame 1. In this way, during the modification of the vulcanizing machine, the existing structure of the gantry vulcanizing machine can be used to install and fix the fan, reducing the modification difficulty and saving modification costs. By installing the fan on the support columns 11 and mounting columns 33 of the gantry frame 1, a multi-point support structure is formed, which improves the support strength of the fan.

[0047] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 5 The blower 2 is movably mounted along the height direction of the blower mounting bracket 3 to adjust the relative height between the blower 2 and the upper vulcanizing chamber mold 101. In this way, different molds may have different depths and shapes, and the blower can be adjusted to the most suitable height according to actual needs. By adjusting the position of the blower along the height direction, the airflow can cover the entire inner cavity depth of the upper vulcanizing chamber mold 101 as much as possible, ensuring the best air drying effect.

[0048] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4-6 The mounting holes 311 include multiple holes, which are spaced apart along the height direction of the fan mounting bracket 3. By connecting the connecting component 21 to the different mounting holes 311, the height of the fan can be adjusted, and the fan can be adjusted to the most suitable height according to actual needs.

[0049] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4-6 The gantry vulcanizing machine includes a controller, which is connected to both the blow molding device and the gantry frame 1 via signals. The controller controls the start of the blow molding device based on the mold opening action of the gantry frame 1. In this way, the upper vulcanizing chamber mold 101 is hoisted to the mold opening position via the gantry frame 1. Upon detecting the mold opening action, the blower 2 of the blow molding device is automatically activated via a PLC programming control program, achieving automatic drying without manual operation. This significantly improves work efficiency and avoids safety hazards.

[0050] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 1 The fan 2 includes multiple fans, each of which is respectively set to correspond to multiple support columns 11 of the gantry frame 1. By setting a fan 2 on each support column 11, it can be ensured that the airflow can act evenly on the upper vulcanizing chamber mold 101 from multiple directions. The simultaneous operation of multiple fans can provide stronger airflow, accelerate the drying speed, and improve the drying efficiency and vulcanization efficiency.

[0051] In some embodiments, the gantry frame 1 includes four support columns 11, and the fans 2 accordingly include four fans. The four fans 2 are arranged in a one-to-one correspondence with the four support columns 11, and are arranged in pairs on the rear support column and the front support column respectively.

[0052] Specifically, see Figure 3 The four blowers 2 are set at an angle upwards and the air outlets are all facing the center of the upper vulcanizing chamber mold 101. The four blowers 2 are all at the same height. With this design, the air blown out by the four blowers 2 will converge directly above the center of the fixed frame to form convection, which can have a good drying effect on the top of the upper vulcanizing chamber mold 101.

[0053] In some embodiments, the fan 2 is a high-power fan with a power of 370W, and the angle between the fan 2 and the horizontal direction is 45 degrees.

[0054] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 7The vulcanizing chamber 10 includes multiple chambers, which are spaced apart along a preset direction. Thus, based on the gantry vulcanizing machine including multiple vulcanizing chambers, a blower 2 is installed on the gantry frame 1. The blower 2 can move with the gantry frame to any vulcanizing chamber 10, allowing the upper vulcanizing mold 101 to immediately enter the blow molding state after vulcanization and mold opening, without needing to be moved to a dedicated blow molding station, thereby improving drying efficiency.

[0055] In the gantry vulcanizing machine with blow molding device in this embodiment, see... Figure 4 A protective plate 4 is installed on the side of the gantry frame 1. The protective plate 4 has an opening 41 to avoid obstructing the airflow generated by the fan 2. By setting the opening 41 to avoid obstructing the airflow generated by the fan 2, the drying effect can be fully guaranteed.
