Description

Technical Field

[0001] This utility model belongs to the field of palletizing equipment technology, specifically relating to a high-strength, low-drop palletizing machine conveyor trolley flatbed mechanism, which is suitable for use in automated palletizing production lines to achieve stable loading and efficient transport of goods. Background Technology

[0002] In modern logistics and manufacturing, palletizers are key equipment for automated warehousing and production, significantly improving the efficiency and accuracy of goods stacking. The conveyor trolley, as the core actuator of the palletizer, is responsible for transporting goods to be palletized from the feeding station to the palletizing station. The flatbed mechanism of the conveyor trolley is the core component that directly supports the goods, and its performance directly determines the working stability, efficiency, and service life of the palletizer.

[0003] The current palletizing machine conveyor trolley flatbed mechanisms on the market have several technical defects: First, the trolleys are relatively thick, reaching 25-40 mm, resulting in a large drop between palletizing layers, reaching 50-70 mm, affecting the palletizing machine's sorting efficiency and stability; Second, the palletizing trolleys have limited applicability. The current market demands diverse and varied product packaging formats, and as a crucial link in beer and beverage production, palletizing machines require extremely high adaptability. Since the palletizing trolley is a vital part of the palletizing machine that comes into contact with the product, improving the machine's efficiency and adaptability is paramount; Third, the load-bearing structure design is unreasonable. Most adopt a frame structure, with welded or bolted connections to the panel, resulting in poor connection strength.

[0004] Therefore, developing a palletizing machine conveyor trolley flatbed mechanism that reduces the drop between pallet layers, adapts to various products, and has high strength and long service life has become an urgent technical need to be addressed in the current palletizing equipment field. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a high-strength, low-drop palletizing machine conveyor trolley flatbed mechanism. The purpose of this utility model is to overcome the technical defects of existing palletizing machine conveyor trolley flatbed mechanisms. By optimizing the structural design and component configuration, it can achieve a comprehensive improvement in reducing the drop of palletizing layers, reducing friction, improving installation and maintenance efficiency, and extending service life.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-strength, low-drop palletizing machine conveyor trolley flatbed mechanism includes: a flatbed body, a reinforcing component, a connecting component, and a friction-reducing component; the reinforcing component is fixed to the lower surface of the flatbed body to improve its structural strength; the connecting component is used to detachably connect the flatbed body to the frame of the conveyor trolley; the friction-reducing component is disposed on the upper surface of the flatbed body.

[0007] Further specifying the above scheme, the plate body is made of low alloy high-strength steel, with a length range of 1450-1600mm, a width range of 1000-1400mm, and a thickness of 8-10mm; the plate body is provided with weight reduction holes.

[0008] A further limitation of the above scheme includes supporting rectangular tubes; the supporting rectangular tubes are disposed on both sides of the flat plate body; Further defining the above solution, the reinforcing component includes multiple reinforcing angle irons; the reinforcing angle irons are welded between the flat plate body and the supporting rectangular tube, and the reinforcing angle irons are arranged at intervals along the width direction of the flat plate body, with a spacing of 200-250mm between adjacent reinforcing angle irons.

[0009] Further defining the above solution, the connecting assembly includes a trolley side roller and a connecting bolt; the trolley side roller is fixed to the supporting rectangular tube by the connecting bolt, and is used to cooperate with the track of the frame to realize the movement of the trolley.

[0010] Further defining the above solution, the connecting bolt is a countersunk bolt, the plate body is provided with a countersunk hole that matches the countersunk bolt, the inner wall of the countersunk hole is provided with internal thread, and its entrance is provided with a chamfer structure.

[0011] Further defining the above solution, the friction-reducing component is a raindrop plate, which is fixed to the upper surface of the flat plate body by spot welding; the surface of the raindrop plate is provided with anti-slip texture and / or coated with an anti-corrosion and wear-resistant coating.

[0012] Further specifying the above scheme, the yield strength of the plate body is ≥345MPa and the rated load-bearing capacity is >500kg.

[0013] Advantages of this utility model compared to the prior art: 1. This solution effectively reduces the drop between palletizing layers: by optimizing the thickness of the flat plate to 8-10mm, the drop between layers during palletizing is significantly reduced (up to 15-25mm), making the packaging stack more stable and the stacking position more neat and aesthetically pleasing. 2. The load-bearing capacity and stability of this solution are significantly improved: The composite reinforcement structure of high-strength low-alloy steel combined with supporting rectangular tubes and reinforcing angle iron greatly improves the bending stiffness and overall load-bearing capacity of the flat plate mechanism, which can withstand a rated load of more than 500kg and has a long service life. 3. This solution is highly adaptable and efficient: the optimized flatbed size can be adapted to various vehicle frames, and the friction-reducing components on the surface (such as raindrop plates) effectively reduce conveying resistance, improve conveying efficiency, and enhance adaptability to different packaged products; 4. This solution is easy and efficient to install and maintain: The connecting components adopt a detachable design such as countersunk bolts, which shortens the installation time of the flat plate and makes it easy to replace damaged parts individually, reducing maintenance costs and downtime; 5. Lightweight and energy-saving design: The flat plate body is equipped with weight-reducing holes and uses lightweight high-strength materials, which reduces the weight of the mechanism while ensuring strength, thus helping to reduce the energy consumption of the conveyor trolley.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] Please see Figure 1-4 The embodiments of this utility model are described in detail below.

[0019] like Figures 1-3 As shown, this utility model provides a high-strength, low-drop palletizing machine conveyor trolley flatbed mechanism, including: a flatbed body 1, a reinforcing component, a connecting component, and a friction-reducing component; the reinforcing component is fixed to the lower surface of the flatbed body 1 to improve its structural strength; the connecting component is used to detachably connect the flatbed body 1 to the frame of the conveyor trolley; the friction-reducing component is disposed on the upper surface of the flatbed body 1. The components work together to form an efficient and stable cargo-bearing and conveying structure.

[0020] The flat plate body 1, as the core component directly supporting the packaged product 9, is made of Q345B low-alloy high-strength steel. This material combines high strength with good welding and processing performance, with a yield strength ≥345MPa, capable of withstanding a rated load of over 500kg, and its weight is 15% lighter than ordinary steel. The flat plate body 1 is designed with a length of 1500mm, a width of 1200mm, and a thickness of 9mm; the palletizer drop can be reduced to 15-25mm, and the palletizing can meet the frame sizes of various pallet palletizer conveyor trolleys. In addition, the flat plate body has internal weight-reduction holes, further reducing the weight of the flat plate without affecting the structural strength, thus reducing the operating energy consumption of the conveyor trolley.

[0021] The supporting rectangular tubes 2 are arranged parallel to each other on both sides of the flat plate body 1, serving as the main longitudinal support frame.

[0022] The reinforcing assembly is used to improve the structural strength and bending stiffness of the trolley's flatbed. The reinforcing assembly includes multiple reinforcing angle irons 3. These angle irons 3 are welded between the flatbed body 1 and the supporting rectangular tube 2, with each angle iron 3 spaced apart along the width direction of the flatbed body 1, and the distance between adjacent angle irons 3 is approximately 220mm. This structure forms multiple stable triangular support points, enhancing the load-bearing capacity of the flatbed in the width direction and effectively reducing the bending deformation of the flatbed.

[0023] The connecting assembly enables detachable connection and precise positioning between the trolley flatbed body and the conveying trolley frame. The connecting assembly includes trolley side rollers 5 and connecting bolts 6. The trolley side rollers 5 are symmetrically fixed to the supporting rectangular tubes 2 on both sides via the connecting bolts 6, allowing them to roll on the frame's track for smooth trolley movement. The connecting bolts 6 are countersunk bolts. The flatbed body 1 has countersunk holes that match the countersunk bolts. The countersunk hole design allows the bolt head to be embedded inside the trolley flatbed, preventing the bolt head from protruding and obstructing cargo transport. The inner wall of the countersunk hole has internal threads, and its entrance has a chamfered structure for easy and quick bolt installation, improving installation efficiency.

[0024] The friction-reducing component is a raindrop plate 4, which is fixed to the upper surface of the flat plate body 1 by spot welding. Its surface is provided with raised anti-slip texture and coated with an anti-corrosion and wear-resistant coating to reduce the friction between the goods and the flat plate surface and improve the damage resistance and corrosion resistance of the trolley flat plate.

[0025] Working principle: such as Figure 4 As shown, during the palletizing process, packaged product 9 (such as a case of beverage) is first conveyed to the roller palletizing station 7 and then pushed onto the surface of the raindrop plate 4 of the trolley flatbed at the receiving position. Due to the low friction of the raindrop plate 4 surface, the product is easily positioned and less prone to scratches. Subsequently, a drive mechanism (such as a chain) drives the trolley side rollers 5 to roll on the track, thereby conveying the entire flatbed mechanism carrying the packaged product 9 to above the palletizing station and aligning it with the already positioned pallet 8. Next, the flatbed mechanism retracts under control (or via other unloading mechanisms), and the packaged product 9, losing support, falls smoothly onto the pallet 8, completing one layer of palletizing. Because the flatbed mechanism is thin and the drop height is small each time, the pallet layers are tightly packed, resulting in a neat and stable stack. Throughout the process, reinforcing components ensure that the flatbed does not deform during loading and movement, and connecting components ensure stable installation and convenient assembly and disassembly.

[0026] The palletizing machine conveyor trolley flatbed mechanism of this utility model has significant advantages in structural design, performance indicators and operating costs. It can be widely used in automated palletizing production lines in the food, pharmaceutical, chemical and logistics industries, promoting the development of palletizing equipment towards high efficiency, stability and intelligence.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
