Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a fast pitch-changing structure for material conveying. Background Art

[0002] In the field of material conveying technology, especially in industries such as iron and steel smelting and machining, efficient material handling is crucial for improving production efficiency. With the continuous improvement of automation, the fast and precise conveying of various materials, especially metal profiles such as angle steel, on the production line has become increasingly important. A reasonable material conveying scheme can not only significantly increase the speed of the entire production process but also effectively reduce labor costs and ensure the safety and stability of production operations.

[0003] For materials with a specific shape such as angle steel, traditional conveying methods often have certain limitations. Angle steel generally has an open triangular shape. When packing, usually 5 openings face upward at the bottom and 4 openings face downward at the top, which is convenient for packing. When conveying on a conveyor belt, angle steel is conveyed at equal intervals with gaps. To improve the packing efficiency and make the distance between angle steels smaller for convenient packing, currently, common solutions usually include, but are not limited to, using fixed baffles arranged at intervals to control the distance between materials or indirectly reducing the gap between materials by adjusting the conveyor belt speed. Although these traditional methods can meet production requirements to a certain extent, they still expose some deficiencies in practical applications.

[0004] Regarding the above related technologies, when using fixed baffles to control the distance between materials, it is difficult to flexibly respond to changes in the size of different batches of materials; when trying to reduce the gap between materials by adjusting the conveyor belt speed, problems such as the inability to ensure the stability of materials may be encountered, which easily causes materials to shift or even overturn during conveying, thus affecting the operation of subsequent processes. In addition, neither of these two methods can effectively meet the requirement of quickly adjusting the adjacent material spacing without changing the layout of the original conveyor line, which is a major challenge for modern factories pursuing high-efficiency production. Utility Model Content

[0005] In order to meet the requirement of quickly adjusting the adjacent material spacing without changing the layout of the original conveyor line, this application provides a fast pitch-changing structure for material conveying.

[0006] The fast pitch-changing structure for material conveying provided by this application adopts the following technical solution:

[0007] A fast pitch-changing structure for material conveying includes a fixing device, a supporting device, and a feeding device;

[0008] The fixing device includes a mounting base and a fixing rod, and the fixing rod is fixed to the mounting base;

[0009] The support device includes a support plate which is rotatably connected along the fixed rod;

[0010] A plurality of feeding devices are provided and arranged in sequence along the long side direction of the support plate. The feeding device includes a fixed frame, a mounting shaft and a support roller. The fixed frame is rotatably connected to the support plate. The mounting shaft passes through the fixed frame and is fixedly connected to the fixed frame. The support roller is sleeved on the mounting shaft and is rotatably connected to the mounting shaft.

[0011] By adopting the above technical solutions, the installation base provides support for the installation of the fixed rod, and the fixed rod provides support for the installation of the support plate, so that the support plate can rotate along the fixed rod. When the support plate rotates along the fixed rod, the horizontal distance of the materials on the support plate will be shortened at this time. The fixed frame rotates along the support plate to keep the materials horizontal. A limiting structure is provided at the fixed rod, and the limiting structure can limit the height of the materials. At this time, the horizontal distance between the materials is shortened. Then the operator drives the materials away from the support roller. The mounting shaft provides support for the installation of the support roller, and can effectively reduce the friction between the support roller and the materials. Then the horizontal distance between the materials can be changed, which is convenient for the operator to perform subsequent related operations.

[0012] Optionally, the cross section of the support roller is an isosceles right triangle, and the hypotenuse of the support roller is close to the side wall of the mounting shaft.

[0013] By adopting the above technical solutions, the support roller is an isosceles right triangle. At this time, the two side walls of the support roller can provide stable support for the materials, and the two side walls of the support roller can provide stable support for both sides of the materials, effectively preventing the materials from shaking.

[0014] Optionally, the edges of the support roller are all rounded.

[0015] By adopting the above technical solutions, the edges of the support roller are all rounded, which can avoid damage to the materials caused by the edges of the support plate.

[0016] Optionally, the support roller is provided with a receiving groove and a positioning groove, and the receiving groove and the positioning groove form a trapezoidal groove. The mounting shaft is provided with a support bearing and a retaining ring. The support bearing is located in the receiving groove, and the support roller is rotatably connected to the mounting shaft through the support bearing. The retaining ring is located in the positioning groove, and the retaining ring abuts against the support bearing.

[0017] By adopting the above technical solution, the accommodation groove provides support for the installation of the support bearing, and the support bearing enables the support roller to rotate along the installation shaft. The setting of the stop ring can stably fix the position of the support bearing, thereby preventing the support bearing from shifting, which in turn affects the stable limiting of the position of the support roller, making the position of the material stable.

[0018] Optionally, a stop ring is clamped between the installation shaft and the fixing frame. One end of the stop ring is fixedly connected to the installation shaft, and the other end is fixedly connected to the fixing frame.

[0019] By adopting the above technical solution, the setting of the stop ring can fix the position of the installation shaft, enabling the installation shaft to be stably fixed at the corresponding position of the fixing frame, thereby providing stable support for the material and preventing the material from shaking.

[0020] Optionally, there are two support plates, and the two support plates are arranged in sequence along the traveling direction of the material. Both ends of the fixing frame are rotatably connected to the support plates.

[0021] By adopting the above technical solution, there are two support plates, which are respectively located on both sides of the fixing frame, and can thus provide stable support for the fixing frame. The fixing frame can provide stable positioning support for the material, preventing the material from shaking and shifting.

[0022] Optionally, a support seat is provided along the long side direction of the installation base, and the support seat is fixedly connected to the installation base. The support seat is used to support the support plate.

[0023] By adopting the above technical solution, the setting of the support seat can support the support plate when the support plate is in a horizontal state. At this time, the support seat can provide stable support for the support plate, preventing the support plate from tilting due to a large load when in a horizontal state, which in turn affects the support effect on the material.

[0024] Optionally, a stop member is provided at the top of the support seat, and the stop member is provided with a positioning groove for accommodating the support plate.

[0025] By adopting the above technical solution, the setting of the stop member can fill the gap between the support plate and the support seat. At the same time, the positioning groove provided at the stop member can limit the support plate, preventing the support plate from rotating when in a horizontal state, which results in a decrease in the support effect on the material.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a support plate and a feeding device, the support plate rotates, and at the same time, the feeding device can, under the positioning of the limiting structure, reduce the distance between materials in the horizontal direction, and the materials are pushed out by the relevant structure for subsequent related operations;

[0028] 2. By setting a support base and a stop member, stable limiting and support can be provided for the support plate;

[0029] 3. By setting a balancing component, the fixing frame can always be kept in a vertical state to provide stable support for the five bars. Description of the Drawings
