Description

Technical Field

[0001] The present invention relates to the technical field of article handling, and particularly to an article handling device for e-commerce. Background Art

[0002] Under the background of the rapid development of e-commerce, the efficiency of logistics and warehousing links has become an important factor affecting overall operations. Especially during the processes of commodity sorting, packing, and loading and unloading, it is often necessary to frequently handle various types and sizes of articles. Traditional manual handling methods are not only inefficient but also have problems such as high labor intensity and easy errors, making it difficult to meet the development needs of modern logistics for high efficiency and intelligence.

[0003] Currently, there are already some handling devices for e-commerce scenarios on the market, such as conveyor belts, robotic arms, or handcarts with fixed clamps. However, these devices generally have the following deficiencies: Firstly, their structural designs are relatively fixed and can only adapt to articles within a specific size range, making it difficult to flexibly handle different specifications of commodities; Secondly, in terms of article clamping, most rely on manual operations or manual adjustment of the clamping mechanism, lacking automatic sensing and adaptive clamping functions, resulting in situations such as articles slipping or tipping during handling, affecting the safety and stability of handling.

[0004] Therefore, an article handling device for e-commerce is needed to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, that is, to solve the problems of the existing article handling device having a small applicable range and poor stability when transporting articles, the present invention provides an article handling device for e-commerce.

[0006] An article handling device for e-commerce includes a bottom plate. A traveling mechanism is provided on the bottom plate. Side sliding plates are symmetrically and slidably installed on both sides of the bottom plate. A driving rod is rotatably installed inside the bottom plate. The driving rod is drivingly connected to the side sliding plates. A bearing seat is fixedly installed at a position near the bottom inside the side sliding plates. The bearing seat slides on the upper surface of the bottom plate. A telescopic plate is slidably installed on the top of the bearing seat. A clamping plate is slidably installed at a position near the top inside the side sliding plates. The clamping plate is located outside the telescopic plate. The clamping plate is drivingly connected to the telescopic plate; by drivingly connecting the side sliding plates with the driving rod, the two side sliding plates can be simultaneously driven to slide towards or away from each other through the driving rod, thereby adjusting the distance between the two telescopic plates to make the device applicable to articles of various widths; by drivingly connecting the sliding telescopic plate with the clamping plate, after the article is placed on the telescopic plate, the weight of the article will press down the telescopic plate, and the descending telescopic plate will drive the clamping plate to clamp the article, which is convenient for operation.

[0007] Preferably, the traveling mechanism includes a rotating shaft. The rotating shafts are rotatably installed at positions near the four corners of the bottom of the bottom plate. A roller is rotatably installed at the bottom end of the rotating shaft. A first motor is fixedly installed on the side of the rotating shaft. The output shaft of the first motor is coaxially and fixedly connected to the roller through a coupling. A second motor is fixedly installed on the upper surface of the bottom plate. The second motor is coaxially and fixedly connected to the top end of the rotating shaft. A limiting ring is coaxially and fixedly installed on the outer surface of the rotating shaft. The limiting ring rotates within the bottom plate. The first motor can drive the roller to rotate, so that the device can move. The second motor can drive the rotating shaft to rotate, so as to drive the device to turn. The limiting ring can prevent the rotating shaft from disengaging.

[0008] Preferably, first telescopic cavities are formed on both sides of the bottom plate. The side sliding plates are L-shaped. The horizontal sections of the side sliding plates slide within the first telescopic cavities. First screw holes are formed on the inner sides of the horizontal sections of the side sliding plates. Two driven bevel gears are rotatably installed inside the bottom plate. One ends of the two driven bevel gears are coaxially and fixedly installed with first screw rods respectively. The outer ends of the two first screw rods are respectively in threaded rotation within the two first screw holes. A driving bevel gear is rotatably installed inside the bottom plate. The two driven bevel gears are both in meshing connection with the driving bevel gear. One end of the driving rod is coaxially and fixedly connected to one end of the driving bevel gear. One end of the driving rod extends to the outside of the bottom plate. By reasonably setting the inclination direction of the threads of the first screw rod and the first screw hole, when the driving rod is rotated, the side sliding plates can slide towards or away from each other simultaneously.

[0009] Preferably, the bearing seat is fixedly connected to the side sliding plate through a connecting rod. A second telescopic cavity is formed at the top of the bearing seat. The telescopic plate slides within the bearing seat through a first abutting spring. The top end of the telescopic plate extends to the outside of the bearing seat.

[0010] Preferably, a first outer tube is fixedly installed at the middle position near the top of the inner side of the side sliding plate. A first inner sliding rod is fixedly installed at the middle position of the outer side of the clamping plate. The first inner sliding rod slides within the first outer tube. A limiting chute is formed on the inner surface of the first outer tube. A limiting slider is fixedly installed at a position near the outer end of the outer surface of the first inner sliding rod. The limiting slider slides within the limiting chute. The limiting slider is connected to the inner end of the limiting chute through a second abutting spring.

[0011] Preferably, two second outer tubes are symmetrically fixedly installed on the inner side of the side sliding plate near the top with respect to the first outer tube. Two second inner sliding rods are fixedly installed at positions near both sides of the outer side of the clamping plate. The two second inner sliding rods respectively slide within the two second outer tubes.

[0012] Preferably, a tooth groove is provided near the middle on the outer side of the telescopic plate. A linkage shaft is rotatably installed through the inside of one of the connecting rods. A gear is coaxially and fixedly installed at the inner end of the linkage shaft. The gear is meshed with the tooth groove. The outer end of the linkage shaft extends into the side sliding plate. A second screw hole is provided at the outer end of the first inner sliding rod. A second screw rod is threadedly installed inside the second screw hole. The outer end of the second screw rod extends into the side sliding plate. The position of the second screw rod inside the side sliding plate is drivingly connected to the position of the linkage shaft inside the side sliding plate through a transmission belt. By providing the second screw rod and the linkage shaft with a driving connection, when the telescopic plate is pressed down, the tooth groove can drive the linkage shaft to rotate through meshing with the gear, and then drive the second screw rod to rotate through the transmission belt. When the second screw rod rotates, it can drive the first inner sliding rod to drive the clamping plate to slide, so as to automatically clamp the article. This setting eliminates the step of manually clamping the article, which is not only simple to operate, but also can increase the stability of the article during transportation. When the second screw rod moves out of the second screw hole, the second abutting spring can abut against the limit slider, so that the end of the second screw hole is always in contact with one end of the second screw rod to ensure that the second screw rod can move threadedly into the second screw hole when the second screw rod rotates in the reverse direction.

[0013] Preferably, a storage cavity is provided inside the telescopic plate. A torsion spring shaft is rotatably installed inside the storage cavity. A connecting belt is wound around the torsion spring shaft. The other end of the connecting belt is wound around the torsion spring shaft inside the other telescopic plate. By providing a connecting belt between the two telescopic plates, it can play a certain role in lifting the article to a certain extent and further enhance the stability. By winding the two ends of the connecting belt around the two torsion spring shafts respectively, the connecting belt can be automatically tightened following the sliding of the telescopic plate, playing an automatic adjustment role.

[0014] Preferably, an inner cavity is provided inside the clamping plate. An inner sliding plate is slidably installed inside the inner cavity. The outer side of the inner sliding plate is connected to the outer side of the inner cavity through a third abutting spring. A through hole is provided through the inner side of the clamping plate. A smooth head is fixedly installed on the inner side of the inner sliding plate. The smooth head passes through the through hole and extends out of the outside of the clamping plate. When the second screw rod completely moves out of the second screw hole, the inner end of the smooth head is flush with the outer side of the telescopic plate. This setting enables the device to still clamp the article when the width of the article exceeds the width between the outer sides of the two telescopic plates and will not damage the article.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By drivingly connecting the side sliding plate and the driving rod, the present invention can drive the two side sliding plates to slide towards or away from each other simultaneously through the driving rod, and then adjust the distance between the two telescopic plates, so that the device is applicable to articles of various widths.

[0017] 2. In the present invention, by drivingly connecting the sliding telescopic plate with the clamping plate, after an article is placed on the telescopic plate, the weight of the article will press down the telescopic plate, and the descending telescopic plate will drive the clamping plate to clamp the article, which is convenient for operation.

[0018] 3. In the present invention, by providing a second screw rod and a linkage shaft that are drivingly connected, when the telescopic plate is pressed down, the tooth groove can drive the linkage shaft to rotate through meshing with the gear, thereby driving the second screw rod to rotate through the transmission belt. When the second screw rod rotates, it can drive the first inner sliding rod to drive the clamping plate to slide, so as to automatically clamp the article. This setting eliminates the step of manually clamping the article, which is not only simple in operation, but also can increase the stability of the article during transportation.

[0019] 4. In the present invention, by providing a connecting belt between the two telescopic plates, it can play a certain role in lifting the article to a certain extent and further enhance the stability. By respectively winding the two ends of the connecting belt around the two torsion spring shafts, the connecting belt can automatically tighten along with the sliding of the telescopic plate, playing an automatic adjustment role.

By reasonably setting the inclination direction of the threads of the first screw rod 16 and the first screw hole 14, when the driving rod 4 is rotated, the side sliding plates 3 can slide towards or away from each other simultaneously.

[0035] As Figure 1 and Figure 4 shown, the bearing seat 5 is fixedly connected to the side sliding plate 3 through a connecting rod 18. A second telescopic cavity 19 is provided at the top of the bearing seat 5. The telescopic plate 6 slides within the bearing seat 5 through a first abutting spring 20.
