Description

Technical Field

[0001] This utility model relates to the technical field of packaging box production lines, specifically to a conveyor for a packaging box production line. Background Technology

[0002] In the production process of packaging boxes, corresponding conveyors need to be arranged on the production line. Referring to the authorized announcement number CN221418930U, an automated packaging production line includes a conveyor, which is horizontally arranged. The anti-drop component includes a motor fixedly installed below the conveyor by a bracket. It can not only prevent the packaging boxes from falling, but also ensure their smooth conveying, and at the same time, it can provide cushioning during material unloading. As described in the above patent, when the existing packaging box production line uses a conveyor, the limiting end of the device only uses two sets of plates to limit the packaging boxes through reciprocating motion. Its movement range is large, and its adaptability to packaging boxes of different sizes is poor. It is easy to damage the packaging boxes due to excessive limiting. Moreover, when the packaging box moves to the non-limiting end of the limiting plate, it is easy to be pushed away from the conveying end, thereby affecting the conveying efficiency of the device. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a conveyor for a packaging box production line, which solves the problems of poor adaptability of the device's limiting end to packaging boxes of different sizes, easy damage to packaging boxes, and impact on the conveying efficiency of packaging boxes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveyor for a packaging box production line, comprising a base, wherein the base is connected to a conveying component for material conveying in the packaging box production line, the conveying component comprising:

[0005] Conveyor belt assembly, mounted on a base, for transporting materials in packaging boxes;

[0006] A limiting component, installed on the base, is used for limiting the movement of packaging boxes on the conveyor belt assembly. The limiting component includes two sets of movable frames slidably connected to the base, and a set of limiting plates for limiting the movement is installed on each of the two sets of movable frames near the middle part of the conveyor belt assembly.

[0007] The positioning component, installed on the base, is used for positioning the adjusting end of the limiting component.

[0008] An adjusting component, mounted on the base and connected to the limiting component, is used to assist in adjusting the position of the conveying packaging box. The adjusting component includes two sets of adjusting plates rotatably connected to the left side of the limiting plate. Two sets of electric push rods are mounted on the base to provide power for the reciprocating swing of the two sets of adjusting plates.

[0009] Preferably, the limiting component further includes a bidirectional screw that is threadedly connected to two sets of movable frames and rotatably connected to the base. A motor for driving the bidirectional screw is installed on the rear side of the base. The motor is a servo motor. The front side of the bidirectional screw is connected to the positioning component.

[0010] Preferably, the bidirectional screw is coaxially fixedly connected to the motor output end, the positioning component includes a positioning disk coaxially fixedly connected to the front side of the bidirectional screw, a miniature cylinder is horizontally mounted on the base near the right side of the positioning disk, a positioning pin for locking the positioning disk is installed on the left extended end of the miniature cylinder, and the side of the positioning disk is provided with a plurality of positioning grooves that match the positioning pins.

[0011] Preferably, the adjusting component further includes two sets of traction frames installed on the left side of the limiting plate to provide support for the adjusting plate. Each of the two sets of traction frames is equipped with a set of bevel gear assemblies for driving the adjusting plate to rotate. The active bevel gears in the two sets of bevel gear assemblies are coaxially fixedly connected to sleeves that are rotatably connected to the traction frames. Each of the two sets of sleeves is slidably connected to a cross shaft that is rotatably connected to the base. A set of gear and rack assemblies driven by an electric push rod is connected to the front and rear sides of the cross shaft, respectively.

[0012] Preferably, the driven bevel gear in the bevel gear assembly is coaxially and fixedly connected to the rotating end of the adjusting plate. The two sets of bevel gear assemblies are symmetrically arranged on the traction frame relative to the middle of the conveyor belt assembly. The sleeve is provided with a cross groove that is slidably connected to the cross shaft. The gear in the gear and rack assembly is coaxially and fixedly connected to the cross shaft. The bottom of the rack in the gear and rack assembly is fixedly connected to the extended end of the electric push rod. The gear and rack in the gear and rack assembly mesh with each other. The adjusting plate is rotatably connected to the traction frame.

[0013] Preferably, a drive motor for driving the conveyor belt assembly is installed on the rear side of the base, and the active conveying roller in the conveyor belt assembly is coaxially and fixedly connected to the output end of the drive motor.

[0014] This utility model provides a conveyor for a packaging box production line. Compared with the prior art, it has the following advantages:

[0015] 1. The conveyor used in this packaging box production line uses limiting and adjusting components within the device. The motor and bidirectional screw work together to adjust the spacing of two sets of moving frames, limiting plates, traction frames, adjusting plates, bevel gear assemblies, and sleeves according to the size of the packaging box. This improves the adaptability of the limiting end of the device to cartons of different sizes. The electric push rod, gear and rack assembly, cross shaft, sleeve, and bevel gear assembly work together to allow the adjusting plates on the left side of the two sets of limiting plates to swing back and forth, moving the cartons to the middle of the conveyor belt assembly. This helps the subsequent two sets of limiting plates to limit the cartons, preventing them from being transported to non-limiting ends and affecting the limiting and transmission effect.

[0016] 2. The conveyor used in this packaging box production line uses positioning components. During the adjustment of the limiting components, the bidirectional screw drives the positioning plate to rotate. After the limiting components are adjusted, the positioning pin is inserted into the positioning groove on the side of the positioning plate by a micro cylinder, thereby locking the positioning plate and the bidirectional screw. This prevents the position of the two sets of moving frames and the limiting plate from being affected by the deflection of the bidirectional screw after the adjustment is completed, thus affecting the limiting operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: A conveyor for a packaging box production line includes a base 1, and a conveying component for material conveying in the packaging box production line is connected to the base 1. The conveying component includes: a conveyor belt assembly 2, installed on the base 1 for conveying packaging box materials; a limiting component 3, installed on the base 1 for limiting the conveying of packaging boxes on the conveyor belt assembly 2, the limiting component 3 including two sets of movable frames 33 slidably connected to the base 1, and a limiting plate 34 for limiting is installed on each of the two sets of movable frames 33 near the middle part of the conveyor belt assembly 2; and a positioning component 4, installed on the base 1 for positioning the adjusting end of the limiting component 3.

[0025] Adjusting component 5, installed on base 1 and connected to limiting component 3, is used to assist in adjusting the position of the conveying packaging box. Adjusting component 5 includes two sets of adjusting plates 52 rotatably connected to the left side of limiting plate 34. Two sets of electric push rods 57 are installed on base 1 to provide power for the reciprocating swing of the two sets of adjusting plates 52. Limiting component 3 also includes bidirectional screws 32 that are threadedly connected to two sets of moving frames 33 and rotatably connected to base 1. A motor 31 for driving bidirectional screws 32 is installed on the rear side of base 1. The motor 31 is a servo motor. The front side of bidirectional screws 32 is connected to positioning component 4. The bidirectional screws 32 and the output end of motor 31 are coaxially fixedly connected.

[0026] The adjusting component 5 also includes two sets of traction frames 51 installed on the left side of the limiting plate 34 to provide support for the adjusting plate 52. Each of the two sets of traction frames 51 has a set of bevel gear assemblies 53 installed on its top for driving the adjusting plate 52 to rotate. The active bevel gears in the two sets of bevel gear assemblies 53 are coaxially fixedly connected to sleeves 54 that are rotatably connected to the traction frames 51. Each of the two sets of sleeves 54 is slidably connected to a cross shaft 55 that is rotatably connected to the base 1. A set of gear and rack assemblies 56 driven by an electric push rod 57 is connected to the front and rear sides of the cross shaft 55 respectively.

[0027] The driven bevel gear in the bevel gear assembly 53 is coaxially and fixedly connected to the rotating end of the adjusting plate 52. Two sets of bevel gear assemblies 53 are symmetrically arranged on the traction frame 51 relative to the middle of the conveyor belt assembly 2. The sleeve 54 is provided with a cross groove that is slidably connected to the cross shaft 55. The gear in the gear rack assembly 56 is coaxially and fixedly connected to the cross shaft 55. The bottom of the rack in the gear rack assembly 56 is fixedly connected to the extended end of the electric push rod 57. The gear and rack in the gear rack assembly 56 mesh with each other. The adjusting plate 52 is rotatably connected to the traction frame 51.

[0028] A drive motor for driving the conveyor belt assembly 2 is installed on the rear side of the base 1. The active conveying roller inside the conveyor belt assembly 2 is coaxially and fixedly connected to the output end of the drive motor. The limiting plate 34 and the adjusting plate 52 are both located on the upper side of the conveyor belt assembly 2. The limiting plate 34 and the adjusting plate 52 are flush with the middle end of the conveyor belt assembly 2, so that the motor 31 and the bidirectional screw 32 cooperate. The distance between the two sets of moving frames 33, the limiting plate 34, the traction frame 51, the adjusting plate 52, the bevel gear assembly 53, and the sleeve 54 can be adjusted according to the size of the packaging box, so that the electric push The rod 57, gear and rack assembly 56, cross shaft 55, sleeve 54, and bevel gear assembly 53 cooperate with each other to make the left adjustment plate 52 of the two sets of limit plates 34 swing back and forth, pushing the carton to the middle of the conveyor belt assembly 2. The electric push rod 57 drives the gear and rack assembly 56 to move back and forth, realizing the reciprocating operation of the cross shaft 55, sleeve 54, and bevel gear assembly 53 without affecting the adjustment of the distance between the limit plates 34 and the adjustment plate 52. This setting avoids the frequent forward and reverse rotation of the motor due to the reciprocating rotation of the cross shaft 55.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The positioning component 4 includes a positioning disk 41 coaxially fixedly connected to the front side of the bidirectional screw 32. A miniature cylinder 42 is horizontally mounted on the right side of the base 1 near the positioning disk 41. A positioning pin 43 for locking the positioning disk 41 is installed on the left extended end of the miniature cylinder 42. The side of the positioning disk 41 is provided with several positioning grooves that match the positioning pin 43. During the adjustment of the limiting component 3, the bidirectional screw 32 drives the positioning disk 41 to rotate. After the limiting component 3 is adjusted, the positioning pin is inserted into the positioning groove on the side of the positioning disk 41 by the miniature cylinder 42, thereby locking the positioning disk 41 and the bidirectional screw 32.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user aligns the left side of conveyor belt assembly 2 with the discharge end of the packaging unit and the right side with the desired transmission end. The motor 31 is then started. The motor 31 adjusts the distance between the two sets of moving frames 33 and the limiting plates 34 via the bidirectional screw 32. During this process, the traction frame 51 drives the adjusting plate 52, bevel gear assembly 53, and sleeve 54 to move with the limiting plates 34. The sleeve 54 slides along the cross shaft 55. Once the distance between the limiting plates 34 matches the width of the packaging box, the motor 31 is turned off. The drive motor then operates the conveyor belt assembly 2, causing the extended ends of the two sets of electric push rods 57 to reciprocate vertically. The electric push rods 57 drive the gear and rack assembly. The internal rack 56 reciprocates, and the reciprocating rack drives the gears to reciprocate, thereby realizing the reciprocating rotation of the cross shaft 55. The reciprocating cross shaft 55 drives the two sets of adjusting plates 52 to swing back and forth through the sleeve 54 and the two sets of bevel gear assemblies 53. When the packaging box produced by the packaging unit moves to the conveyor belt assembly 2, the conveyor belt assembly 2 transports it. When the packaging box approaches the two sets of adjusting plates 52, the two sets of adjusting plates 52 continuously push it to the middle of the conveyor belt assembly 2. Then, under the action of the conveyor belt assembly 2, the packaging box is transported to the required transmission end through the two sets of limiting plates 34. The conveyor belt assembly 2 is existing technology, so its internal structure and working principle will not be described in detail.
