Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically to a liner blanking machine for welding square tube liners. Background Technology

[0002] In the field of prefabricated buildings and steel structure manufacturing, square tubes are common structural components. To improve the strength and precision of butt joints or connections between square tubes, it is often necessary to weld backing plates at specific locations inside the square tubes. These backing plates are usually small rectangular plates that serve to position, support, or reinforce the connection during the welding process.

[0003] Currently, in the welding process of square tube liners, the loading of liners is mostly done manually. Operators need to manually pick up the liners one by one from the material pile and place them into the predetermined welding position inside the square tube. This manual operation method has many drawbacks: First, the production efficiency is low, making it difficult to match the cycle time of automated welding equipment, thus becoming a bottleneck process in the production line; second, the repetitive manual picking and placing of materials is labor-intensive and easily leads to operator fatigue; third, in a fast-paced production environment, the accuracy of manual placement may fluctuate, affecting the subsequent welding quality; in addition, there are safety hazards such as high temperature and arc light near the welding station, and manual operation increases safety risks.

[0004] Therefore, there is an urgent need for a device that can automatically, continuously, and accurately feed liners to improve the automation level of welding production lines, ensure the stability of product quality, and reduce labor costs and operational risks. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of low efficiency, poor accuracy, high labor intensity and safety hazards in the manual placement of lining plates in the prior art, and to provide a lining plate feeding machine for welding square tube lining plates that has a reasonable structure, reliable operation and can automatically and continuously feed materials.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a liner feeding machine for welding square tube liners, including a storage rack and an ejection mechanism. The ejection mechanism is fixedly installed on one side of the bottom end of the storage rack and is used to eject the liners stacked in the storage rack one by one. The storage rack includes a first slide and a second slide arranged in parallel opposite directions, and a connecting end plate fixedly connected to both ends of the first slide and the second slide. A feeding channel is formed between the first slide and the second slide to accommodate the horizontal stacking of the liner plates. The width of the feeding channel is slightly larger than the width of a single liner plate, so that the liner plates can fall smoothly in it without getting stuck. The actuator of the ejection mechanism is aligned horizontally with the bottommost liner in the feeding channel. After the ejection mechanism ejects the bottommost liner horizontally, the liner above it automatically falls to the ejection position under gravity.

[0007] Preferably, the mounting base of the ejection mechanism is fixed to the two connecting end plates located on the rear side of the second carriage.

[0008] Preferably, the connecting end plate has a feed inlet at the position corresponding to the feeding channel, and the width of the feed inlet is the same as the width of the feeding channel, for supplementing the liner plate into the feeding channel through the feed inlet.

[0009] Preferably, a plurality of limiting plates are provided at intervals along the length of the outer side of the first carriage, and the lower end of the limiting plates extends downward and beyond the bottom surface of the first carriage to limit the liner pushed out by the pushing mechanism, ensuring that it is pushed to the predetermined position.

[0010] Preferably, a plurality of connecting and reinforcing plates are fixedly connected between the top ends of the first carriage and the second carriage to enhance the overall structural strength of the storage rack.

[0011] Preferably, the launching mechanism includes: The mounting plate is fixed at both ends to the connecting end plate of the storage rack, and the mounting plate and the bottom of the storage rack form a pushing channel with a height slightly greater than the thickness of the liner. A cylinder mounting plate is fixedly mounted on the mounting plate. A cylinder, the cylinder body of which is horizontally fixed to the cylinder mounting plate; The drive plate is movably connected to the piston rod of the cylinder via a vertically arranged connecting rod, and is driven by the cylinder to perform horizontal reciprocating motion; Multiple L-shaped paddles are evenly distributed along the length of the drive plate. The first end of each L-shaped paddle is movably connected to the drive plate, and the middle inflection point is movably connected to the mounting plate. A connecting rod, one end of which is movably connected to the second end of the L-shaped lever; A push plate is movably connected to the other end of the connecting rod and is used to directly push the liner plate; In addition, a plurality of guide grooves are provided on the push plate and a limiting post is fixed on the mounting plate or frame. The limiting post passes through the guide groove, so that the push plate moves horizontally and reciprocally in a stable direction defined by the guide groove under the drive of the drive plate.

[0012] The advantages of this utility model compared to the prior art are as follows: The storage rack of this utility model is used for horizontally stacking and storing multiple liner plates, with a discharge port at its bottom. The ejection mechanism is located on one side of the discharge port of the storage rack and is used to horizontally eject the bottommost liner plate. The storage rack includes a first and second slide arranged in parallel opposite directions, and a connecting end plate fixedly connected to both ends of the two slides. A feeding channel slightly wider than the width of the liner plate is formed between the first and second slides, allowing the liner plate to fall naturally under gravity within this channel. The connecting end plate not only provides a stable connection but also has a feeding port for easy replenishment of liner plates. The ejection mechanism converts the linear motion of the cylinder into a stable horizontal reciprocating motion of the pusher plate, thereby accurately ejecting the bottommost liner plate to a predetermined position. Both ends of the ejection mechanism are fixed to the connecting end plate of the storage rack to ensure overall rigidity and operational stability. A limiting plate is provided on the outside of the first slide to limit the position of the ejected liner plate, ensuring that it is accurately pushed to the welding fixture or designated position. A connecting reinforcement plate is installed at the top of the first and second carriages to enhance the rigidity of the storage rack and prevent deformation over long-term use. This invention enables automatic and continuous feeding of liner plates, allowing for in-line operation with automated welding equipment and significantly improving production efficiency. The optimized ejection mechanism and storage channel design ensure that only one liner plate is ejected at a time, with accurate positioning, which helps guarantee welding quality. The overall structure of this invention is rationally designed, with fewer parts, low manufacturing cost, and easy installation and maintenance. It replaces manual material handling, reducing the labor intensity of operators and minimizing human intervention in the welding area, thus improving operational safety. By adjusting the size of the storage channel and the position of the push plate, this invention can adapt to the feeding requirements of liner plates of different sizes. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the following description is intended to explain the present invention, and not to limit the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the present invention provides a liner feeding machine for welding square tube liners, which mainly consists of two parts: a storage rack 1 and an ejection mechanism 2.

[0022] The storage rack 1 serves as a storage and guiding component for the liners. Its core is a feeding channel formed by the parallel arrangement of the first slide 11 and the second slide 12. The width of this channel is precisely designed, slightly larger than the width of a single liner, allowing the liners to be stacked horizontally and slide smoothly under gravity without tilting or jamming due to excessive gaps. Two connecting end plates 13 are firmly fixed to the ends of the first slide 11 and the second slide 12 by welding or bolting, forming a rigid frame structure. The connecting end plates 13 have inlets 14, allowing for convenient addition of liners when the channel is depleted or needs replenishment. To enhance overall stability, several connecting reinforcing plates 16 are welded to the top of the first slide 11 and the second slide 12. Several downward-extending limiting plates 15 are welded to the outside of the first slide 11 to limit the final position of the ejected liners, ensuring their accurate arrival at the welding station.

[0023] The ejection mechanism 2 is responsible for performing the unloading action. Its mounting plate 21 is fixed to two connecting end plates 13 connected to the rear side of the second slide 12 by bolts. A pushing channel with a height slightly greater than the thickness of the liner is formed between the mounting plate 21 and the bottom of the storage rack 1. The cylinder 25 is horizontally mounted on the mounting plate 21 via the cylinder fixing plate 23. The piston rod of the cylinder 25 is connected to the drive plate 22 via the connecting rod 24. Multiple L-shaped paddles 26 are connected by pins and other connecting parts, with one end hinged to the drive plate 22, the middle inflection point hinged to the mounting plate 21, and the other end hinged to the push plate 28 via the connecting rod 27. Multiple horizontal guide grooves 210 are provided on the push plate 28, and the limiting post 29 passes through these guide grooves and is fixed to the mounting plate 21 or other fixed parts.

[0024] The work process is as follows: Initially, multiple liner plates are stacked in the feeding channel of the storage rack 1, with the bottommost liner plate located in the pushing channel and aligned with the push plate 28. The piston rod of the cylinder 25 extends, pushing the drive plate 22 away from the storage rack via the connecting rod 24. The drive plate 22 drives the L-shaped paddle 26 to rotate around its central fulcrum, and the L-shaped paddle 26 then pulls the push plate 28 backward (initially reset) via the connecting rod 27. When feeding is required, the piston rod of the cylinder 25 retracts, pulling the drive plate 22 towards the storage rack 1. This action is converted into a horizontal linear motion of the push plate 28 towards the storage rack 1 via the transmission of the L-shaped paddle 26 and the connecting rod 27 (the motion trajectory is ensured by the guide groove 210 and the limiting post 29). During the forward movement of the push plate 28, the bottommost liner plate is pushed horizontally out of the feeding channel until it is blocked by the limiting plate 15, completing one feeding cycle. Once the bottom liner is pushed out, all the liners above it automatically fall one layer under gravity, and the bottom liner returns to its original position, awaiting the next push-out action. This cycle repeats, achieving continuous automatic feeding of the liners.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. For example, the power source of the ejection mechanism is not limited to a cylinder, but can also be an electric push rod, a hydraulic cylinder, etc.; the transmission mechanism can also adopt other linkage combinations or cam mechanisms, etc.; the specific shape and size of the storage rack can be adjusted according to the specifications of the liner plate.
