Description

Technical Field

[0001] This utility model relates to a transportation mechanism, specifically belonging to the technical field of workshop cardboard box transportation devices. Background Art

[0002] As is well known, in fields such as industrial construction, chemical industry, and food, finished products are often packaged in bags, and then loaded onto trucks for transportation. In order to achieve transportation between different layers, transportation mechanisms are often installed between the layers to meet the needs of transportation packaging between layers.

[0003] Traditional lifting and transport mechanisms typically use a chain plate support structure to carry cardboard boxes. A motor drives the chain plate to move it to the designated floor. After the cardboard box is in place, it needs to be manually pushed around. During the pushing process, there will be friction damage between the bottom of the cardboard box and the support plate, resulting in serious damage to the bottom of the cardboard box.

[0004] Currently, there are some parcel carton lifting and conveying devices on the market, such as the one shown in application number 202023052960.2. These devices use a conveyor belt to support the carton in the support structure of traditional lifting and conveying mechanisms. However, the aforementioned lifting and conveying mechanisms often have the following problems in actual use:

[0005] After the cardboard boxes are transported to the designated location, they need to be manually pushed from the conveyor belt to the floor, resulting in a low level of automation.

[0006] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative vertical downward transport carton mechanism to overcome the defects in the prior art. Utility Model Content

[0007] The purpose of this utility model is to provide a vertical downward transportation mechanism for cardboard boxes that automatically transports them from high floors to low floors, occupies little space, and has a low maintenance cost due to its single-chain structure.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a machine body, an upper conveyor belt installed at the front top of the machine body, and a lower conveyor belt installed at the rear bottom of the machine body. It also includes a chain drive mechanism, several chain plates, and a support mechanism installed on the machine body. The chain drive mechanism includes a chain, a sprocket assembly, and a motor that drives the sprocket assembly. The chain is installed on the sprocket assembly. The top surface of the chain is lower than the top surface of the upper conveyor belt, and the top surface of the chain is higher than the top surface of the lower conveyor belt. The front end of the chain plate is installed on the chain through a support rod. The chain plate also includes a roller, which is rotatably connected to the rear end of the chain plate. When the chain plate transports the carton, the support mechanism cooperates with the rear end of the chain plate to support the carton.

[0009] By adopting the above technical solution and using a single chain structure, the device occupies a small volume. The front end of the chain plate is connected to the chain through a support rod. When the carton enters the chain plate, the front end of the carton moves together with the front end of the chain plate, and the rear end of the carton moves together with the rear end of the chain plate. This avoids the bottom of the carton from sliding and rubbing against the chain plate, which would cause wear on the bottom of the carton. Furthermore, the cooperation between the chain plate and the support mechanism achieves the purpose of automatically transporting the carton from the upper conveyor belt to the lower conveyor belt.

[0010] The vertical downward transport carton mechanism of this utility model is further configured such that the movement path of the chain is "L" shaped.

[0011] The vertical downward conveying carton mechanism of this utility model is further configured as follows: the support mechanism includes a roller, a blocking rail and a support rail. The roller is installed on the top of the machine body and is used to support the rear end of the chain plate when the chain plate conveys the carton at the top of the machine body. The blocking rail is installed vertically on the machine body and is used to restrict the movement of the rear end of the chain plate when the chain plate conveys the carton vertically downward. The support rail is installed horizontally on the bottom of the machine body and is used to support the rear end of the chain plate when the chain plate conveys the carton at the bottom of the machine body.

[0012] By adopting the above technical solution, the support mechanism is used to restrict the movement of the rear end of the chain plate in order to achieve smooth transportation of cardboard boxes.

[0013] The vertical downward transport carton mechanism of this utility model is further configured such that: a through groove is opened on the path at the top of the chain on the blocking rail, and the height of the through groove is greater than the diameter of the support rod and less than the diameter of the roller.

[0014] By adopting the above technical solution, the through groove provides space for the support rod to move, and the blocking roller passes through the through groove, so that the front end of the chain plate can pass through the through groove, and the rear end of the chain plate abuts against the blocking rail.

[0015] The vertical downward transport carton mechanism of this utility model is further configured such that when one end of the chain plate is located on the chain and the other end is located on the blocking rail, the chain plate is parallel to the ground.

[0016] By adopting the above technical solution, the front end of the chain plate is rotatably connected to the chain, and the rear wheel slides on the blocking rail, so that the chain plate remains stable when transporting the carton downwards.

[0017] The vertical downward transport carton mechanism of this utility model is further configured such that: the blocking rail is "L" shaped, and the distance between the bottom of the blocking rail and the support rail is equal to the diameter of the roller.

[0018] By adopting the above technical solution, when the chain plate vertically transports the carton at the bottom of the machine, the rollers are restricted between the support rail and the blocking rail to ensure that the carton is transported smoothly.

[0019] The vertical downward transport carton mechanism of this utility model is further configured as follows: the distance between the support rod axis and the support rail, and the distance between the roller and the support rail.

[0020] By adopting the above technical solution, it is ensured that the front and back of the carton are at the same height when the chain plate is at the bottom, thus achieving stable transportation of the carton.

[0021] The vertical downward transport carton mechanism of this utility model is further configured such that an annular groove is opened on the roller to facilitate the passage of the roller.

[0022] By adopting the above technical solution, the annular groove provides a range for the movement of the rear wheel, preventing the roller from causing the chain plate to tilt upwards after passing the roller, which would affect the stability of transporting the carton.

[0023] The vertical downward transport mechanism for cartons of this invention is further configured such that the rollers are made of elastic material.

[0024] By adopting the above technical solution, the roller can abut against the blocking rail when it moves on the blocking rail to maintain the smooth movement of the chain plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The vertical downward transport carton mechanism of this utility model can automatically transport the carton from a high place to the bottom of the carton through the cooperation between the chain, chain plate and support mechanism. No manual handling is required, and the carton and chain plate remain relatively stationary, avoiding damage to the bottom of the carton.

[0027] 2. The vertical downward transport carton mechanism of this utility model adopts a single chain structure, which occupies little space.

[0028] 3. The vertical downward transport carton mechanism of this utility model has a simple overall structure, which is easy to disassemble, assemble and maintain.

[0029] 4. The distance between the middle sprocket group and the middle and rear sprocket groups of the vertical downward carton transport mechanism of this utility model is adjustable to adapt to the transport of cartons in different environments. Attached Figure Description

[0036] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 6 As shown, this utility model is a vertical downward conveying carton mechanism, including a machine body 1, an upper conveyor belt 21 installed at the top front end of the machine body 1, and a lower conveyor belt 22 installed at the bottom rear end of the machine body 1. A chain drive mechanism 3 is installed on the machine body 1. The chain drive mechanism 3 consists of a chain 31, a sprocket set 32, and a motor 33 that drives the sprocket set 32 ​​to move. The chain 31 is installed on the sprocket set 32, and the motor 33 is used to drive the sprocket set 32 ​​to rotate so as to drive the chain 31 to rotate.

[0037] The movement path of the chain 31 is "L" shaped. In this embodiment, the sprocket group 32 includes an upper front sprocket 321 and an upper middle sprocket 322 located at the top of the machine body 1, a middle middle sprocket 323 and a middle rear sprocket 324 in the middle of the machine, and a lower rear sprocket 325 and a lower front sprocket 326 at the bottom of the machine body 1. These are located at the six corners of the chain 31, thereby realizing the "L" movement trajectory of the chain 31. The top surface of the top of the chain 31 is lower than the top surface of the upper conveyor belt 21, and the top surface of the bottom of the chain 31 is higher than the top surface of the lower conveyor belt 22 to ensure the stability of the carton transportation. The distance between the middle middle sprocket 323 and the middle rear sprocket 324 can be adjusted according to actual needs.

[0038] The front end of the chain plate 4 is mounted on the chain 31 via a support rod 41. The support rod 41 is used to support the front end of the chain plate 4. When the chain plate 4 is transporting the carton, the support mechanism 5 cooperates with the roller 42 at the rear end of the chain plate 4 to support the rear end of the chain plate 4. The support mechanism 5 includes a roller 51, a blocking rail 52, and a support rail 53.

[0039] Roller 51 is installed between the upper front sprocket 321 and the upper middle sprocket 322. Roller 51 has an annular groove 511 to facilitate the passage of roller 42. This groove supports the rear end of chain plate 4 after the front end of chain plate 4 passes the upper front sprocket 321. The annular groove 511 provides a range for the movement of the rear wheel, preventing the roller 42 from causing the chain plate 4 to tilt upwards after passing through roller 51, which would affect the stability of transporting the carton.

[0040] The blocking rail 52 is installed between the upper front sprocket 321, the upper middle sprocket 322, the middle middle sprocket 323, and the middle rear sprocket 324. When one end of the chain plate 4 is on the chain 31 and the other end is on the blocking rail 52, the chain plate 4 is parallel to the ground. The blocking rail 52 has a through groove 521 on the path at the top of the chain 31. The height of the through groove 521 is greater than the diameter of the support rod 41 but less than the diameter of the roller 42. The through groove 521 provides space for the support rod 41 to move, and the blocking roller 42 passes through... The front end of the chain plate 4 can pass through the through groove 521, and the rear end of the chain plate 4 abuts against the blocking rail 52. The blocking rail 52 is used to restrict the movement of the roller 42 when the front end of the chain plate 4 is located between the upper and middle sprockets 322 and the middle sprocket 323. When the chain plate 4 is transporting the carton downwards, the rear wheel slides on the blocking rail 52 to maintain a stable state. The roller 42 is made of elastic material. When the roller 42 moves on the blocking rail 52, it can abut against the blocking rail 52 to maintain the smooth movement of the chain plate 4.

[0041] The support rail 53 is installed between the middle sprocket 323, the middle rear sprocket 324, the lower rear sprocket 325, and the lower front sprocket 326. It is used to support the rear end of the chain plate 4 after the front end of the chain plate 4 passes the middle sprocket 323. The blocking rail 52 is L-shaped. The distance between the bottom of the blocking rail 52 and the support rail 53 is equal to the diameter of the roller 42. The distance between the axis of the support rod 41 and the support rail 53 and the distance between the roller 42 and the support rail 53 is the same. When the chain plate 4 vertically transports the carton at the bottom of the machine body 1, the roller 42 is restricted between the support rail 53 and the blocking rail 52 to ensure that the front and rear heights of the carton are consistent when the chain plate 4 is at the bottom, so as to achieve stable transport of the carton.

[0042] The working principle of the vertical downward carton transport mechanism of this utility model is as follows:

[0043] When it's necessary to transport packed cardboard boxes from upstairs to downstairs, the boxes are placed on the upper conveyor belt 21. As the upper conveyor belt 21 rotates, one end of the box enters the front end of the chain plate 4. The motor 33 is started, and the motor 33 drives the chain 31 to rotate. The chain 31 drives the chain plate 4 to move, and the chain plate 4 drives the front end of the box to move. When the box leaves the upper conveyor belt 21, one end of the box is fixed to the front end of the chain plate 4, and the other end is fixed above the roller 51. As the box leaves the roller 51, the rollers 42 and the blocking rails 52 abut against each other, and the support rod 41 passes through the upper and middle sprockets 3. 22 moves downwards, causing the chain plate 4 and the carton to move horizontally downwards together. When the support rod 41 passes the middle sprocket 323, the roller 42 and the support rail 53 abut against each other. The chain 31 carries the chain plate 4 and the carton horizontally. When the support rod 41 passes the middle rear wheel, it moves downwards. At this time, the front end of the carton leaves the chain plate 4 and enters the lower conveyor belt 22 until it is completely on the lower conveyor belt 22. After the support rod 41 passes the lower rear sprocket 325 and the lower front sprocket 326, it returns to the lower conveyor belt 21. The above steps are repeated to achieve the purpose of continuous transportation of the carton.

[0044] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
