Description

Technical Field

[0001] This utility model relates to the technical field of warehouse automation, and in particular to a conveying device. Background Technology

[0002] In industrial production, conveyor tables are core equipment for material handling, and their durability and stability directly affect production efficiency and maintenance costs. A key problem currently facing conveyor systems is that when goods are placed on the conveyor surface, the impact load and continuous pressure generated by the goods' own weight cause multiple types of damage to the conveyor surface structure. This damage mainly manifests in the following aspects:

[0003] 1. Surface wear: The continuous friction between the bottom of the goods and the conveyor rollers or table will cause the surface material to wear rapidly, especially when conveying bulk materials or heavy goods, the wear rate will increase exponentially;

[0004] 2. Structural deformation: Under concentrated load, the conveyor roller structure may undergo plastic deformation. Long-term bearing of loads exceeding the design standard will cause the roller shaft to bend and deform, forming a "dent effect".

[0005] 3. Loose fasteners: Dynamic impact loads can cause fasteners (such as bolts, rivets, etc.) to vibrate and loosen. According to statistics, this type of problem accounts for about 23% of conveyor failures.

[0006] 4. Drive system overload: Sudden loading may cause instantaneous current overload of the motor, which will shorten the service life of the reducer by 30-40% over a long period of time;

[0007] 5. Edge damage: Positioning deviations when placing goods often lead to collision damage to the edges of the platform. This type of damage is especially common in loading and unloading processes with low levels of automation. Utility Model Content

[0008] In view of the above-mentioned problems of existing conveyor platforms, the present invention aims to provide a conveying device in which multiple buffer components are connected between the upper and lower frames for buffering.

[0009] The specific technical solution is as follows:

[0010] A conveying device includes a frame and a plurality of rollers, characterized in that the frame is composed of an upper frame and a lower frame, and the upper frame and the lower frame are connected by a plurality of buffer components;

[0011] Each of the aforementioned buffer components includes:

[0012] The guide component has its lower end fixedly connected or vertically slidably connected to the lower frame, and its upper end correspondingly vertically slidably connected or fixedly connected to the upper frame.

[0013] A spring is sleeved on the guide member, and the upper and lower ends of the spring abut against the upper frame and the lower frame, respectively.

[0014] A resistance element is used to prevent the guide element from sliding between the upper or lower frame.

[0015] In the aforementioned conveying device, the resistance element is an elastic pad, which is sleeved on the sliding end of the guide element;

[0016] The sliding end of the guide member has a thread and is provided with an adjusting nut to restrict the elastic pad.

[0017] In the aforementioned conveying device, the resistance element is a rubber sleeve, which is disposed in the through hole of the upper or lower frame.

[0018] The sliding end of the guide has a rough surface and slides and frictionally engages with the rubber sleeve.

[0019] In the aforementioned conveying device, the elastic coefficient of the spring is increased, or the number of the buffer components is increased along the conveying direction.

[0020] In the aforementioned conveying device, both the upper frame and the lower frame are provided with guide rings, and the upper and lower ends of the spring extend into the two guide rings respectively.

[0021] In the aforementioned conveying device, a plurality of the buffer components are distributed at the four corners of the upper frame, and at least two of the buffer components are provided at each corner of the upper frame.

[0022] In the aforementioned conveying device, a plurality of sliding rods are provided between the upper frame and the lower frame, and the plurality of sliding rods are distributed at the four corners of the lower frame.

[0023] The aforementioned conveying device further includes a driving component. Each roller has a conveying sprocket installed at both ends. The driving component is equipped with a driving sprocket, which is connected to the conveying sprocket via a chain to drive the roller to rotate.

[0024] In the aforementioned conveying device, the conveying sprocket at one end of the roller is connected to the conveying sprocket of the preceding roller by a chain, and the conveying sprocket at the other end is connected to the conveying sprocket of the following roller by a chain.

[0025] In the aforementioned conveying device, the top surface of at least one side of the upper frame is provided with a plurality of mounting slots, and the plurality of mounting slots are distributed along the conveying direction;

[0026] The plurality of mounting slots correspond to one end of the plurality of rollers respectively, and are for detaching and attaching one end of the rollers.

[0027] The positive effects of the above technical solution compared with the existing technology are:

[0028] This utility model uses multiple buffer components to connect the upper and lower frames for buffering, thereby achieving the buffering and release of the impact force of the goods.

[0029] This utility model can prevent the left and right sway between the upper and lower frames during use by using the guide component, and can prevent the sliding between the guide component and the upper or lower frame by using the resistance component, thus preventing damage caused by frequent collisions between the upper and lower frames after the spring is compressed and released.

[0030] This utility model achieves power transmission in a bow shape by arranging multiple chains in a double-sided staggered manner on the basis of a single driving component, thus preventing roller warping;

[0031] The upper frame of this invention has an added mounting groove on its top surface, which facilitates the installation and disassembly of the rollers and enables quick replacement when the rollers are damaged. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0040] like Figures 1 to 6 As shown, a preferred embodiment of the conveying device is illustrated, including a frame and a plurality of rollers 52. The frame consists of an upper frame 1 and a lower frame 2, which are connected by a plurality of buffer components 3.

[0041] This invention uses multiple buffer components 3 to connect the upper frame 1 and the lower frame 2 for buffering, thereby achieving the buffering and release of the impact force of the goods.

[0042] Furthermore, in a preferred embodiment, each buffer assembly 3 includes: a guide 31, a spring 32, and a resistance member 33. The lower end of the guide 31 is fixedly connected to or vertically slidably connected to the lower frame 2, and the upper end of the guide 31 is correspondingly vertically slidably connected to or fixedly connected to the upper frame 1. The spring 32 is sleeved on the guide 31, and the upper and lower ends of the spring 32 abut against the upper frame 1 and the lower frame 2, respectively. The resistance member 33 is used to prevent the sliding between the guide 31 and the upper frame 1 or the lower frame 2.

[0043] Furthermore, guide member 31 is a guide screw.

[0044] Furthermore, as a preferred embodiment, each buffer assembly 3 further includes: a first locking nut 34 and a second locking nut 35, both of which are connected to the guide member 31 and lock the guide screw 31 to the upper frame 1 or the lower frame 2.

[0045] Furthermore, when the lower end of the guide member 31 is fixedly connected to the lower frame 2, the upper end of the guide member 31 is vertically slidably connected to the upper frame 1; the first locking nut 34 and the second locking nut 35 cooperate longitudinally to lock the lower end of the guide member 31 to the lower frame 2.

[0046] Alternatively, when the lower end of the guide member 31 is vertically slidably connected to the lower frame 2, the upper end of the guide member 31 is fixedly connected to the upper frame 1. The first locking nut 34 and the second locking nut 35 longitudinally cooperate to lock the lower end of the guide member 31 to the upper frame 1.

[0047] This utility model can prevent the left and right sway between the upper frame 1 and the lower frame 2 during use by means of guide member 31, and can prevent the sliding between guide member 31 and upper frame 1 or lower frame 2 by means of resistance member 33, and prevent the upper frame 1 and lower frame 2 from being damaged due to frequent collisions after the spring 32 is compressed and released.

[0048] Furthermore, as a preferred embodiment, the resistance element 33 is an elastic pad or a rubber sleeve.

[0049] When the resistance element 33 is an elastic pad, it is sleeved on the sliding end of the guide element 31. The sliding end of the guide element 31 has threads and is provided with an adjusting nut 36 to restrict the elastic pad.

[0052] When the resistance element 33 is a rubber sleeve, it is installed in the through hole of the upper frame 1 or the lower frame 2. The sliding end of the guide element 31 has a rough surface and slides and rubs against the rubber sleeve.

[0053] Preferably, when the length of the guide member 31 is sufficient, the sliding end of the guide member 31 does not need to be provided with a limiting member, and the friction between the rough surface of the guide member 31 and the rubber sleeve plays a damping role.

[0054] Furthermore, as a preferred embodiment, the elastic coefficient of the spring 32 is increased, or the number of buffer components 3 is increased along the conveying direction of the conveying device.

[0055] Preferably, the vibration gradually decreases from the input end to the output end of the conveying device, resulting in more stable delivery to the next workstation.

[0056] Furthermore, as a preferred embodiment, both the upper frame 1 and the lower frame 2 are provided with guide rings 37, and the upper and lower ends of the spring 32 extend into the two guide rings 37 respectively.

[0057] Furthermore, as a preferred embodiment, multiple buffer components 3 are distributed at the four corners of the upper frame 1, with at least two buffer components 3 provided at each corner of the upper frame 1.

[0058] Furthermore, as a preferred embodiment, a plurality of sliding rods 4 are provided between the upper frame 1 and the lower frame 2, and the plurality of sliding rods 4 are distributed at the four corners of the lower frame 2.

[0059] Furthermore, as a preferred embodiment, the conveying device also includes a drive unit 51, with conveying sprockets 53 installed at both ends of each roller 52, and a drive sprocket 54 installed on the drive unit 51. The drive sprocket 54 is connected to the conveying sprocket 53 via a chain 55 to drive the roller 52 to rotate.

[0060] The driving component 51 is a motor.

[0061] Furthermore, in a preferred embodiment, the conveyor sprocket 53 at one end of the roller 52 is connected to the conveyor sprocket 53 of the preceding roller 52 via a chain 55, and the conveyor sprocket 53 at the other end is connected to the conveyor sprocket 53 of the following roller 52 via a chain 55.

[0062] Based on a single drive component 51, this utility model achieves power transmission in a bow shape by arranging multiple chains 55 in a double-sided staggered manner, thus preventing the roller 52 from warping.

[0063] Furthermore, as a preferred embodiment, the top surface of at least one side of the upper frame 1 is provided with a plurality of mounting slots 61, which are distributed along the conveying direction of the conveying device.

[0064] Furthermore, in a preferred embodiment, the plurality of mounting grooves 61 correspond to one end of the plurality of rollers 52 respectively, and allow one end of the rollers 52 to be installed or removed.

[0065] This utility model, by providing an installation groove 61, facilitates the installation and disassembly of the roller 52, enabling rapid replacement of the roller 52 when it is damaged.
