Description

Technical Field

[0001] The utility model belongs to the technical field of material transportation, and particularly relates to a conveyor line lifting device. Background Art

[0002] With the prevalence of automation, conveyor belts are now commonly used for material transfer in aluminum can production lines. Especially in two-piece can production lines, in order to improve production efficiency, it is often the case that the same conveyor line conveys two-piece cans of various types. However, when the conveyor line is connected to the next process, such as filling, sealing, inspection, packaging, etc., since these large machines are difficult to adjust the height, when changing the two-piece cans of various types, the height of the conveyor line needs to be frequently adjusted to match the subsequent large machines. Adjusting the height of the conveyor line requires manual disassembly and leveling of the conveyor line, and the entire process is time-consuming and labor-intensive. Therefore, there is an urgent need for a device that can quickly adjust the height of the conveyor line to adapt to conveyor lines that convey various types of cans.

[0003] For example, the technical solution in patent CN202322641209.3 includes a rotating rod and a lifting body connected to the left and right ends of the rotating rod. The lifting body includes a lifting seat with guide rods, a conveyor belt base, and a balancing rod. Guide columns arranged along the height direction are respectively provided at both ends of the lifting seat in the longitudinal direction. The conveyor belt base is slidably connected to the two guide columns. An adjustment arm group is hingedly connected to the conveyor belt base at each end of the lifting seat in the longitudinal direction. The balancing rod is hingedly connected between the two adjustment arm groups and is threadedly connected to the rotating rod. This technical solution uses the adjustment arm groups at both ends of the conveyor belt to achieve the technical effect of raising and lowering the conveyor belt.

[0004] However, this solution utilizes a scissor-type lifting mechanism, which requires locking pins to secure the structure after it is raised. This makes the conveyor line lifting device complex to operate, especially when the lifting height is high and the load is located outside the scissors, which may cause tilting or shaking, resulting in insufficient stability. Furthermore, because the scissors need to be unfolded, the scissor-type lifting mechanism requires a large space when folded, resulting in unnecessary space waste. Utility Model Content

[0005] The utility model aims to overcome the defects of the prior art in that the lifting operation of the conveyor line is complicated, the stability is poor, and it is difficult to lift synchronously, and provides a conveyor line lifting device to overcome the above problems.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention is implemented through the following technical solutions:

[0007] A conveyor line lifting device, comprising:

[0008] A roller assembly, conveyor line side plates arranged on both sides of the roller assembly, a base arranged under the conveyor line side plates, and a conveyor line bracket supporting the base; two or more height connection components fixed under the conveyor line side plates, a worm gear elevator arranged on the base and corresponding to the height connection components, and the output shaft of the worm gear elevator is connected to the height connection component.

[0009] In the field of material handling, since large-scale machinery used for filling, sealing, inspection, and packaging is relatively difficult to adjust in height, a relatively simple method when changing can types on a conveyor line is to adjust the conveyor line height. When adjusting the conveyor line height, the first consideration is ease of adjustment. Because production requirements often require downtime, adjusting the conveyor line height can affect the entire production process and reduce production efficiency. Secondly, after adjusting the conveyor line height, it is necessary to ensure that the conveyor line angle remains the same as before the adjustment. Otherwise, it is easy to cause belt deviation, which may pose a production safety hazard.

[0010] The utility model sets a height connection component on the side panel of the conveyor line to facilitate the disassembly and assembly of the device. A worm gear elevator is set on the base at a position corresponding to the height connection component to adjust the height of the conveyor line. The worm gear transmission has a self-locking function, which means that after the power input is stopped, the worm gear elevator can remain in its original position and will not fall due to gravity, saving the step of locking the elevator. In addition, the worm gear elevator can provide very precise lifting control. At the same time, the worm gear transmission can achieve a high reduction ratio. A small input torque can generate a large output torque. It is suitable for lifting high-load and heavy-weight conveyors, and can realize lifting operations while the conveyor belt is loaded.

[0011] Preferably, a synchronous actuator is provided between the worm gear elevators to enable the worm gear elevators to be raised and lowered synchronously. In practice, due to the long conveyor line, multiple worm gear elevators need to be installed. The provision of a synchronous actuator between them not only enables synchronous lifting, but also reduces the workload of leveling after lifting.

[0012] As a further preferred embodiment, the synchronous actuator includes a coupling provided on the base, and a connecting shaft connecting the worm gear elevator and the coupling. The worm gear elevator on one side of the conveyor line operates synchronously through the coupling and the connecting shaft.

[0013] As a further preferred embodiment, the synchronous actuator further comprises a synchronous transmission shaft for connecting the coupling. The synchronous transmission shaft is arranged between the couplings at corresponding positions on both sides of the conveyor line, so that the worm gear elevators on both sides can work synchronously.

[0014] As a further preferred feature, the base is provided with a handle mounting base, which is provided with a through-hole capable of accommodating a connecting shaft. A handle mounting base can be provided at the end of the conveyor line, with the drive shaft extending through the through-hole in the handle mounting base and connected to the handle. The worm gear elevator is controlled by rotating the handle, making it convenient for a single person to operate the conveyor.

[0015] Preferably, the height connection assembly is L-shaped, with one end fixedly connected to the conveyor line side panel and the other end extending horizontally to connect to the output shaft of the worm gear elevator. This L-shaped height connection assembly not only ensures the stability of the conveyor line, but also reduces the conveyor line's footprint while expanding the conveyor line width, achieving a larger conveyor belt area.

[0016] Preferably, the conveyor line support is provided with a height adjustment base. The height adjustment base is provided between the conveyor line support and the ground. When the elevator is raised or lowered, if the ground is uneven or there are errors in the worm gear conveyor, even synchronous lifting may cause local unevenness. In this case, the height of a certain support leg can be locally adjusted to fine-tune the conveyor line.

[0017] Preferably, a support plate is provided between the side plates of the conveyor line for fixing the side plates of the conveyor line on both sides. Since the conveyor line needs to be frequently raised and lowered, a higher requirement is placed on the stability of the conveyor line. Therefore, the support plate is provided to further enhance the anti-torsion and stability of the conveyor line.

[0018] Preferably, the upper edge of the conveyor line side plate is provided with a stopper to prevent the conveyor belt from deflecting. The conveyor line belt may deflect during the lifting operation, and the stopper is provided to play a limiting role.

[0019] Preferably, the conveyor side panels are provided with bearing seats for mounting the drive shaft, and the bearing seats are provided with bearing mounting and adjustment components for adjusting the drive shaft angle. If the drive shaft is found to be offset due to the raising and lowering of the conveyor, the bearing mounting and adjustment components can be adjusted to restore the output shaft to perpendicularity with the conveyor side panels.

[0020] Therefore, the utility model has the following beneficial effects:

[0021] (1) The utility model ensures the stability of the conveyor before and after lifting through the worm gear elevator, and can provide precise lifting control;

[0022] (2) The utility model achieves synchronous lifting effect through synchronous actuators, which can ensure the overall parallelism of the conveyor line and keep the gap between the tank mouth and the lifting belt consistent, without causing tank mouth crushing or tank falling problems.

[0023] (2) The utility model has a relatively simple structure, and the lifting is quick and efficient. It can be operated by one person, and the cost is low, which is conducive to its promotion and application in production practice. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Based on these descriptions, a person skilled in the art will be able to implement the present invention. Furthermore, the embodiments of the present invention described below generally represent only a portion of the present invention, rather than all of the embodiments. Therefore, all other embodiments derived by a person skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0032] like Figure 1-6As shown, the roller assembly 1, conveyor side panels 2, base 3, and conveyor support 4 in this embodiment are components of a conventional conveyor line. The conveyor belt is sleeved over the roller assembly 1. The conveyor side panels 2 are positioned on either side of the roller assembly to prevent the belt from slipping. A support plate 11 is positioned between the conveyor side panels 2 for fixing. The conveyor support 4 supports the base 3, which in turn supports the conveyor side panels 2. To achieve the desired conveyor line height adjustment, multiple worm gear elevators 6 are mounted on the base 3, with a maximum travel of 150 mm. Multiple L-shaped height connection assemblies 5 are secured beneath the conveyor side panels 2, corresponding one to each of the worm gear elevators 6 on the base. Each height connection assembly 5 has an inwardly extending extension 9, with the output shaft of the worm gear elevator 6 mating with the extension 9. Furthermore, a height adjustment seat 10 is positioned between the conveyor support 3 and the ground for fine-tuning, with a maximum travel of 30 mm. To synchronize the operation of the multiple worm gear elevators 6, a synchronous actuator 20 is provided. A coupling 21 is provided on the base 3 between the worm gear elevators 6. The coupling 21 has three connection points, two of which are connected to the worm gear elevators 6 on the left and right sides via connecting shafts 22, and the remaining connection point is connected to the coupling 21 on the other side via a synchronous transmission shaft 23. A handle mounting seat 7 is provided on the end base 3 of the conveyor line. The connecting shaft 22 is connected to the handle via a through hole 8 on the handle mounting seat 7, so that when the handle is rotated, the multiple worm gear elevators 6 on both sides of the conveyor line are driven to work synchronously. To reduce the deviation caused by the lifting and lowering of the conveyor line, blocks 12 are provided at intervals along the upper edge of the conveyor line side plate 2 to prevent the conveyor belt from deviating. The entire conveyor line is driven by a drive shaft that drives the belt wrapped around the roller assembly 1. The drive shaft is provided on a bearing seat 13 on the conveyor line side plate 2. A bearing mounting adjustment assembly 14 that is adjusted by screws is provided below the bearing seat 13.

[0033] The usage process of this embodiment is as follows:

[0034] When the conveyor line needs to be raised or lowered to adjust the material being conveyed, the handle on the handle mounting base 7 is manually rotated to rotate the connecting shaft 22. This not only drives the worm gear elevator 6 on the same side, but also transmits power to the coupling 21. This power is then transmitted to the coupling 21 on the other side via the synchronous drive shaft 23, and the connecting shaft 22 connected thereto drives the worm gear elevator 6 on that side. This achieves the effect of synchronously transmitting power to the worm gear elevators 6 on the entire conveyor line by rotating the handle. The worm gear elevator 6 rises or falls as the connecting shaft 22 rotates. When the handle is stopped, the conveyor line height is fixed. At this time, if the elevation of a certain part of the conveyor line deviates, fine-tuning can be performed using the height adjustment base 10 at that location. If the output shaft is not perpendicular to the conveyor line side plate 2, fine-tuning can be performed using the bearing mounting adjustment assembly 14. Once the conveyor line is leveled, the conveyor line can be allowed to continue operating.
