Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a material roll raising device for a feeding trolley. Background Technology

[0002] In modern industrial production, many processes rely on raw materials in coil form, such as metal processing, packaging and printing, and textiles. With the continuous improvement of production automation, loading trolleys have become a key tool for transporting coils to processing equipment.

[0003] Currently, the common material loading process requires two or more people to complete. One person operates the overhead crane or forklift, while another person or more is responsible for pushing and positioning. If the roll material is too heavy or too wide, it will inevitably swing a lot during hoisting, which can easily cause collisions and damage to the material and machine. This not only results in long downtime and high labor intensity for each material loading and changing, but also poses significant safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a material roll elevation device for a loading trolley, which solves the problem mentioned in the background technology that if the roll is too heavy or too wide, it will inevitably swing greatly during hoisting, easily causing collisions and damaging the materials and machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material roll raising device for a loading trolley, comprising a trolley upper plate, the trolley upper plate being mounted on a lifting platform, and fixed plates installed at both the front and rear ends of the top of the trolley upper plate, the top of the fixed plates being arc-shaped, and tie rods being bolted between the fixed plates at the front and rear ends of the trolley upper plate, with support plates equidistantly installed on the tie rods, and a pin being provided through the top of the support plate, the pin being parallel to the tie rods and positioned between the tops of the two fixed plates, with a roller rotatably mounted on the pin.

[0006] Preferably, the upper plate of the trolley is provided with an auxiliary component, which includes a mounting frame. Two sets of mounting frames are provided and are respectively fixedly installed on the left and right sides of the upper plate of the trolley by bolts. A rotating shaft is rotatably installed on the mounting frame, and a connecting plate is fixedly installed on both ends of the rotating shaft. An auxiliary roller is rotatably installed between the two connecting plates.

[0007] Preferably, a rotating rod is rotatably mounted between the mounting brackets on the left and right sides of the upper plate of the trolley, and the rotating rod is connected to the output end of the motor.

[0008] Preferably, worm gears are provided at both ends of the rotating rod, the worm gears mesh with worm wheels, and the worm wheels are fixedly installed in the middle of the rotating shaft.

[0009] Preferably, the worm gears at both ends of the rotating rod have opposite helical directions.

[0010] Preferably, the top height of the connecting plate in its vertical state is higher than the height of the idler roller.

[0011] This utility model provides a material roll raising device for a feeding trolley. It has the following beneficial effects:

[0012] (1) This utility model can directly support and fix the material roll through the trolley plate, fixing plate, tie rod, support plate and other structures, which can enhance the overall stability, keep the material roll stable during transportation and loading, and prevent it from shaking, thereby reducing the risk of collision and avoiding damage to materials and machine.

[0013] (2) The height of the auxiliary roller of this utility model can be adjusted by rotating the shaft and the connecting plate. The top height of the connecting plate in the vertical state is higher than the height of the support roller, which makes the device adaptable to material rolls of different diameters and weights. For material rolls with larger diameters, the auxiliary roller can be adjusted to a suitable height to provide support; for material rolls with smaller diameters, it can also be adjusted to ensure stability, thus improving the versatility of the device while supporting the material rolls.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figures 1-4 This utility model provides a material roll raising device for a feeding trolley, including a trolley upper plate 1, which is installed on a lifting platform. Fixed plates 2 are installed at both the front and rear ends of the top of the trolley upper plate 1. The top of the fixed plates 2 is arc-shaped. Tie rods 4 are bolted between the fixed plates 2 at the front and rear ends of the trolley upper plate 1. Support plates 7 are installed at equal intervals on the tie rods 4. A pin 6 is provided through the top of the support plate 7. The pin 6 is parallel to the tie rods 4 and is set between the tops of the two fixed plates 2. A roller 5 is rotatably mounted on the pin 6.

[0022] Specifically, the tie rod 4 is bolted between the fixing plates 2 at both ends. It connects the two fixing plates 2 into a single unit, enhancing the lateral stability of the device and preventing deformation or displacement of the fixing plates 2 due to the weight of the material roll or external forces. Furthermore, the tie rod 4 provides a mounting base for the support plate 7, which is equidistantly mounted on the tie rod 4, with a pin 6 penetrating its top. The support plate 7 acts as an intermediate support, distributing the weight of the material roll across the tie rod 4 and the fixing plates 2, reducing the stress on individual components. Simultaneously, the equidistant distribution design ensures uniform support for the material roll, preventing deformation or tilting due to uneven support, further improving the stability of the material roll support.

[0023] Because the idler roller 5 has low frictional resistance when rotating, it can reduce wear on the surface of the material roll, avoid scratches and other damage caused by friction, help protect the surface quality of the material roll, and ensure that the material roll can maintain good quality in subsequent processing. Stable support and low frictional resistance can reduce the stress and wear on the idler roller 5 itself and related components such as pins 6 and support plates 7, extend the service life of these components, reduce equipment maintenance costs and replacement frequency, and ensure the long-term stable operation of the material roll raising device for the loading trolley.

[0024] Furthermore, to further improve the stability of the coil, please refer to [link / reference needed]. Figures 1-4An auxiliary component 3 is provided on the upper plate 1 of the trolley. The auxiliary component 3 includes a mounting frame 31. There are two sets of mounting frames 31, which are fixedly installed on the left and right sides of the upper plate 1 of the trolley by bolts. A rotating shaft 32 is rotatably installed on the mounting frame 31. A connecting plate 35 is fixedly installed on both ends of the rotating shaft 32. An auxiliary roller 36 is rotatably installed between the two connecting plates 35.

[0025] A rotating rod 34 is rotatably mounted between the mounting brackets 31 on the left and right sides of the upper plate 1 of the trolley, and the rotating rod 34 is connected to the output end of the motor 33;

[0026] Worms 341 are provided on both ends of the rotating rod 34. The worms 341 mesh with worm wheels 321, and the worm wheels 321 are fixedly installed in the middle of the rotating shaft 32.

[0027] The worm gears 341 at both ends of the rotating rod 34 have opposite helical directions;

[0028] The top of the connecting plate 35 in its vertical position is higher than the height of the idler roller 5.

[0029] Specifically, the auxiliary roller 36 in the auxiliary component 3 is installed between the connecting plates 35. When the material roll is placed on the support roller 5, the auxiliary roller 36 can provide support from both sides of the material roll to prevent the material roll from swaying or shifting in the horizontal direction. Especially for material rolls with a large width or a high center of gravity, it can effectively enhance its lateral stability and prevent the material roll from tipping over due to external forces.

[0030] The rotating rod 34 is connected to the motor 33. The worm gears 341 at both ends of the rotating rod 34 mesh with the worm wheels 321 mounted on the rotating shaft 32, and the helical directions of the worm gears 341 are opposite. When the motor 33 drives the rotating rod 34 to rotate, the worm gears 341 on both sides will drive the worm wheels 321 to rotate, thereby causing the rotating shaft 32 to rotate, realizing the angle adjustment between the connecting plate 35 and the auxiliary roller 36. The angle of the auxiliary roller 36 can be flexibly adjusted according to the actual situation of the material roll, such as its diameter, so that it can better fit the side of the material roll, provide stable support, and further improve the stability of the material roll.

[0031] By using motor 33 to drive rotating rod 34, the angle adjustment of auxiliary roller 36 can be automated. Compared with manual adjustment of the support device, automated adjustment can adjust the support status more quickly and accurately according to the material roll condition, improving operational efficiency and ensuring the timeliness and accuracy of support. This helps maintain the stability of the material roll under different working conditions and reduces the instability of the material roll caused by untimely or inadequate manual adjustment. At the same time, by adjusting the angle and position of auxiliary roller 36, the support requirements of material rolls with different diameters and widths can be met, expanding the applicability of the material roll raising device for the loading trolley. Regardless of the type of material roll, good stability support can be obtained through auxiliary component 3, improving the versatility and practicality of the equipment.

[0032] Working principle: The material roll is hoisted onto the support roller 5 of the lifting device using a gantry crane. The support roller 5 supports the material roll. According to the size of the material roll, the rotating rod 34 can be driven by the motor 33. Through the meshing transmission of the worm gear 341 and the worm wheel 321, the rotating shaft 32 is adjusted so that the connecting plate 35 drives the auxiliary roller 36 to rotate to a suitable angle. This allows the auxiliary roller 36 to fit tightly against the material roll from both sides, providing lateral support and preventing the material roll from swaying or shifting horizontally, thus further improving the stability of the material roll. Then, the lifting device and trolley are used to transport the material roll to the designated position for easy unloading.
