Description

Technical Field

[0001] This utility model relates to a conveying device, specifically an inbound and outbound conveying device. Background Technology

[0002] Logistics and express delivery inbound and outbound conveyor systems are devices used to transport and sort express packages. Inside existing logistics parks, express packages are often first transferred to conveyor belts by transport machines, and then transported by conveyor belts.

[0003] However, existing conveyor belts are often of fixed length, which limits their ability to be adjusted or shortened.

[0004] Therefore, existing conveyor belts and their structures still have the limitation of not being able to adjust the distance. Summary of the Invention

[0005] The purpose of this utility model is to provide an inbound and outbound conveying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An inbound / outbound conveying device includes a long support leg and a short support leg. The short support leg is disposed on one side of the long support leg. An upper side frame is disposed on the top of the long support leg. A lower side frame is slidably disposed on the surface of the upper side frame. The end of the lower side frame away from the upper side frame is slidably connected to the short support leg. An extension mechanism of the lower side frame is disposed between the long support leg and the short support leg.

[0008] The extension mechanism includes a sleeve fixedly connected to a short leg, the sleeve being used to push the short leg out from one side of the long leg to extend the transmission length.

[0009] As described above, the inbound and outbound conveying device has a first roller rotatably mounted on the long support leg. One end of the first roller is connected to a drive motor, and the drive motor is mounted on the upper side frame.

[0010] As described above, the inbound / outbound conveying device has a second roller rotatably mounted on the lower frame. The second roller is located on one side of the first roller, and the distance between the second roller and the first roller can be extended.

[0011] As described above, the inbound / outbound conveying device has a long crossbeam on one side of the long support leg and a short crossbeam on one side of the short support leg, with the short crossbeam slidably connected to the long crossbeam, and the short crossbeam can be pulled out from inside the long crossbeam.

[0012] As described above, the inbound and outbound conveying device has the following features: a motor is installed inside the long crossbeam, and a lead screw is installed at one end of the output shaft of the motor. The surface of the lead screw is threadedly connected to a sleeve, and the sleeve is installed on the inner wall of the short crossbeam.

[0013] As described above, the inbound and outbound conveying device has a guide block on the side of the long crossbeam, a sliding cylinder body on the inner wall of the guide block, a connecting rod rotatably connected to the bottom of the sliding cylinder body, and the other end of the connecting rod is rotatably connected to the short crossbeam.

[0014] As described above, the inbound and outbound conveying device has a piston rod slidably disposed inside the cylinder body, an adjusting roller rotatably disposed on the top of the piston rod, and a conveyor belt is rolled and tensioned on the first roller, the second roller and the adjusting roller.

[0015] As described above, the inbound / outbound conveying device has the following features: a convex circle at the bottom of the piston rod; a lower spring inside the cylinder body; the bottom of the lower spring abuts against the inner wall of the bottom of the cylinder body; the top of the lower spring abuts against the convex circle of the piston rod; and an upper spring is fitted onto the surface of the piston rod, with the bottom of the upper spring abutting against the top of the convex circle and the top of the upper spring abutting against the inner wall of the top of the piston rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting the traditional fixed conveyor belt to an adjustable conveyor belt, the length of the conveyor belt can be extended, so that the conveyor belt can extend more per unit time, thereby increasing the timeliness of express delivery in and out of the warehouse.

[0017] This utility model also includes a conveyor belt tension adjustment mechanism. By providing adjustable height of the adjusting roller, the adjusting roller can be elastically connected to the belt tension between the first roller, the second roller, and itself. As the conveyor belt extends with the lower frame, it always maintains tension between the three rollers, ensuring the stability of inbound and outbound conveying. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figures 1-10 As an embodiment of this utility model, the inbound and outbound conveying device includes a long support leg 1 and a short support leg 4. The short support leg 4 is disposed on one side of the long support leg 1. An upper side frame 2 is disposed on the top of the long support leg 1. A lower side frame 3 is slidably disposed on the surface of the upper side frame 2, and the end of the lower side frame 3 away from the upper side frame 2 is slidably connected to the short support leg 4. An extension mechanism of the lower side frame 3 is disposed between the long support leg 1 and the short support leg 4.

[0031] The extension mechanism includes a sleeve 12, which is fixedly connected to the short support leg 4. The sleeve 12 is used to push the short support leg 4 out from one side of the long support leg 1 to extend the transmission length.

[0032] In this embodiment, as shown in the figure, a long support leg 1 is provided on the left side and a short support leg 4 is provided on the right side. An upper side frame 2 is installed on the top of the long support leg 1, and a lower side frame 3 is slidably installed on the top of the short support leg 4. The lower side frame 3 can slide on the short support leg 4 during the outward extension process. The extension mechanism is driven by the sleeve 12.

[0033] As a further embodiment of this utility model, a first roller 5 is rotatably mounted on the long support leg 1, one end of the first roller 5 is connected to a drive motor, and the drive motor is mounted on the upper side frame 2.

[0034] In this embodiment, a first roller 5 is installed on the long support leg 1, and a drive motor is installed at one end of the first roller 5 to drive the first roller 5 to rotate.

[0035] As a further embodiment of this utility model, a second roller 6 is rotatably mounted on the lower frame 3. The second roller 6 is located on one side of the first roller 5, and the distance between the second roller 6 and the first roller 5 can be extended.

[0036] In this embodiment, a second roller 6 is installed on the lower side frame 3, and the second roller 6 can extend along the distance between the lower side frame 3 and the first roller 5.

[0037] As a further embodiment of this utility model, a long crossbeam 8 is provided on one side of the long support leg 1, and a short crossbeam 9 is provided on one side of the short support leg 4. The short crossbeam 9 is slidably connected to the long crossbeam 8, and the short crossbeam 9 can be pulled out from the inside of the long crossbeam 8.

[0038] In this embodiment, a long crossbeam 8 is installed on the side of the long support leg 1, and a short crossbeam 9 is installed on the side of the short support leg 4. One end of the short crossbeam 9 is located inside the long crossbeam 8, and the short crossbeam 9 can extend to one side.

[0039] As a further embodiment of this utility model, a motor 10 is provided inside the long crossbeam 8, and a lead screw 11 is provided at one end of the output shaft of the motor 10. The surface of the lead screw 11 is threadedly connected to the sleeve 12, and the sleeve 12 is provided on the inner wall of the short crossbeam 9.

[0040] In this embodiment, when it is necessary to extend the short crossbeam 9, the motor 10 inside the long crossbeam 8 is started. The output shaft of the motor 10 will drive the lead screw 11 to rotate. Since the lead screw 11 and the sleeve 12 are threadedly connected, the sleeve 12 will be driven. The sleeve 12 is fixedly installed on the inner wall of the short crossbeam 9, thereby restricting radial rotation and allowing the sleeve 12 to move only axially, thereby driving the short crossbeam 9 to be pulled out inside the long crossbeam 8.

[0041] As a further embodiment of this utility model, a guide block 13 is provided on the side of the long crossbeam 8, a sliding cylinder 14 is slidably provided on the inner wall of the guide block 13, a connecting rod 15 is rotatably provided at the bottom of the sliding cylinder 14, and the other end of the connecting rod 15 is rotatably connected to the short crossbeam 9.

[0042] Ball bearings are provided between the guide block 13 and the cylinder body 14 to reduce the friction between them.

[0043] In this embodiment, when the short crossbeam 9 is pulled out from inside the long crossbeam 8, as... Figure 1 As shown, it will move to the right, and there is a connecting rod 15 rotatably connected between the cylinder body 14 and the short crossbeam 9. When the short crossbeam 9 pulls the connecting rod 15 to move to the right, the cylinder body 14 will be squeezed and lifted on the inner wall of the guide block 13.

[0044] As a further embodiment of this utility model, a piston rod 16 is slidably arranged inside the cylinder body 14, and an adjusting roller 7 is rotatably arranged on the top of the piston rod 16. A conveyor belt 17 is rolled and tensioned on the first roller 5, the second roller 6 and the adjusting roller 7.

[0045] In this embodiment, in conjunction with all the embodiments described above, when the conveying length is extended, the lower frame 3 extends outward from the surface of the upper frame 2, and the short crossbeam 9 extends outward from the inside of the long crossbeam 8, thereby increasing the distance between the second roller 6 and the first roller 5. When the distance increases, the conveyor belt 17 is stretched very tightly on both surfaces. Therefore, an adjusting roller 7 can be provided at the bottom. When the second roller 6 pulls the conveyor belt 17 outward, the short crossbeam 9 at the bottom is pulled out from the inside of the long crossbeam 8. Thus, the connecting rod 15 will drive the sliding cylinder 14 to rise inside the guide block 13, thereby raising the piston rod 16 and causing the adjusting roller 7 to rise, thereby achieving a corresponding balance between the first roller 5, the second roller 6, and the adjusting roller 7.

[0046] As a further embodiment of this utility model, the bottom of the piston rod 16 is provided with a convex circle, and the interior of the cylinder body 14 is provided with a lower spring 19. The bottom of the lower spring 19 abuts against the bottom inner wall of the cylinder body 14, and the top of the lower spring 19 abuts against the convex circle of the piston rod 16. An upper spring 18 is sleeved on the surface of the piston rod 16. The bottom of the upper spring 18 abuts against the top of the convex circle, and the top of the upper spring 18 abuts against the top inner wall of the piston rod 16.

[0047] In this embodiment, in conjunction with the previous embodiment, when the adjusting roller 7 is lifted, the lower spring 19 pushes the piston rod 16 upward, causing the piston rod 16 to move upward. As the piston rod 16 moves upward, the convex circle at its bottom pulls and compresses the upper spring 18. Therefore, the adjusting roller 7 is always in an elastically connected state on the conveyor belt 17, thereby buffering the tension between the first roller 5 and the second roller 6. In conjunction with the adjusting roller 7, the conveyor belt 17 is elastically connected on the surfaces of the three rollers, allowing the conveyor belt 17 to obtain corresponding tension as the conveying length extends.

[0048] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
