Description

Technical Field

[0001] This utility model relates to the field of box gluing machine technology, and in particular to a paper feeding mechanism for a box gluing machine. Background Technology

[0002] A carton gluing machine is a device for forming paper boxes. It has multiple processes such as pre-folding, bottom hooking, body folding, and pressing. The paperboard is rotated between these processes by a paper feeding mechanism. The main structure of the paper feeding mechanism is several conveyor belts arranged side by side. The paperboard is placed on the conveyor belts and is conveyed forward by friction. However, when the paperboard is being conveyed, the slippage between the paperboard and the conveyor belt can cause uneven spacing between the front and rear paperboards, and even cause the paperboard to fly off the conveyor belt, which has a significant impact on subsequent processing steps.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a paper feeding mechanism for a box gluing machine, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A paper feeding mechanism for a carton gluing machine includes a frame and conveyor belts. Several conveyor belts are arranged side by side on the frame and are driven by a first motor mounted on the frame. A suction motor is mounted on the frame. A main suction pipe is connected to the air inlet of the suction motor. Several suction branch pipes are connected to the main suction pipe and pass through several conveyor belts. Several air inlet pipes with upward openings are connected to the suction branch pipes. Several suction holes are opened on the conveyor belts.

[0006] Preferably, the frame is provided with a plurality of first mounting plates, and a first pulley is rotatably mounted on the first mounting plate. A drive shaft is rotatably mounted on the frame and is connected to the first motor through the cooperation of a synchronous pulley and a synchronous belt. The conveyor belt is wound around the first pulley and the drive shaft.

[0007] Preferably, the frame is provided with a plurality of auxiliary belts located between two adjacent conveyor belts.

[0008] Preferably, the frame is provided with a plurality of second mounting plates located between two adjacent first mounting plates, and a second pulley is rotatably mounted on the second mounting plate, and the auxiliary belt is wound around the second pulley and the drive shaft.

[0009] Preferably, the frame is fixedly provided with two mounting rods perpendicular to the conveying direction of the conveyor belt, and the first mounting plate and the second mounting plate are respectively fixedly connected with a first mounting foot and a second mounting foot that are slidably disposed on the mounting rods, and fastening bolts that abut against the mounting rods are screwed onto the first mounting foot and the second mounting foot.

[0010] Preferably, the frame is provided with two guide plates located on both sides of the conveyor belt conveying direction and parallel to the conveyor belt conveying direction.

[0011] Preferably, two support rods perpendicular to the conveying direction of the conveyor belt are fixedly installed on the frame. Two adjusting plates are respectively located on one side of the two guide plates on the support rods. The guide plates are set on the adjusting plates. A drive screw that is rotatably connected to a second motor installed on the frame is rotatably installed on the frame. The two adjusting plates are respectively screwed onto two threaded sections with opposite directions of rotation on the drive screw.

[0012] Preferably, the adjusting plate is composed of a fixed plate and a movable plate. The fixed plate is fixedly mounted on the adjusting plate. The adjusting plate has an adjusting groove parallel to the conveying direction of the conveyor belt. The movable plate is fixedly connected with a plurality of adjusting bolts passing through the adjusting groove. After passing through the adjusting groove, the adjusting bolts are screwed with adjusting nuts that are tightly abutting against the adjusting plate.

[0013] In summary, the beneficial effects of this utility model are as follows: When the cardboard is placed on the conveyor belt and conveyed with it, the suction motor creates a pressure difference between the upper and lower ports of the suction hole through the action of the main suction pipe, the branch suction pipe and the inlet pipe, which adsorbs the cardboard placed on the conveyor belt, keeping the cardboard stably on the conveyor belt and conveying it with it. This prevents the cardboard from flying off the conveyor belt during the conveying process and ensures that the front and rear spacing of several cardboards conveyed with the conveyor belt remains consistent. This, in turn, ensures that the cardboard is stably transferred from the pre-processing mechanism of the gluing machine to the post-processing mechanism, thus ensuring the stable operation of the gluing machine.

Detailed Implementation

[0017] 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.

[0018] As shown in the figure, a paper feeding mechanism of a box gluing machine includes a frame 1 and a conveyor belt 2. Several conveyor belts 2 are arranged side by side on the frame 1 and are connected to a first motor 3 on the frame 1. A suction motor 4 is arranged on the frame 1 below the conveyor belts 2. A suction main pipe 51 is connected to the air inlet of the suction motor 4. Several suction branch pipes 52 are connected to the suction main pipe 51 and pass through several conveyor belts 2. Several air inlet pipes 53 with upward openings are connected to the air inlet pipes 52. Several air inlets 21 are opened on the conveyor belts 2. The openings of the air inlet pipes 53 are close to the air inlets 21.

[0019] Specifically, the conveyor belt 2 is mounted on the frame 1 and connected to the first motor 3 via a transmission connection. The frame 1 has several first mounting plates 22, each with a first pulley 23 rotatably mounted on it. A drive shaft 6, connected to the first motor 3 via a synchronous pulley and belt, is also rotatably mounted on the frame 1. The conveyor belt 2 is wound around the first pulley 23 and the drive shaft 6. The main suction pipe 51 passes through a mounting groove in the first mounting plate 22 and extends perpendicularly to the conveying direction of the conveyor belt 2, resting on the first mounting plate 22. The first mounting plate 22 provides support for the main suction pipe 51, ensuring the stability of the main suction pipe 51, the suction branch pipe 52, and the air inlet pipe. When the first motor 3 drives the drive shaft 6 to rotate, the drive shaft 6 simultaneously drives several conveyor belts 2, thus ensuring the synchronicity of the several conveyor belts 2 during operation.

[0020] In the above structure, after the cardboard is processed, it is transferred to the conveyor belt 2 and conveyed to the subsequent processing mechanism. During the process of the cardboard being conveyed by the conveyor belt 2, the suction motor 4 works, causing air to enter the suction pipe through the opening of the suction pipe and be drawn away by the suction motor 4 through the suction branch pipe 52 and the suction main pipe 51 in sequence, which accelerates the air flow at the lower port of the suction hole 21. There is a pressure difference between the upper and lower ports of the suction port, which acts as an adsorption for the cardboard placed on the conveyor belt 2 through the suction port. This makes the cardboard more stable on the conveyor belt 2 during the process of conveying, thereby preventing the cardboard from flying off the conveyor belt 2 during the process of conveying. It also ensures that the front and rear spacing of the cardboard conveyed by the conveyor belt 2 is consistent, thereby ensuring the stable transfer of the cardboard from the pre-processing mechanism of the gluing machine to the subsequent processing mechanism and ensuring the stable operation of the gluing machine. In order to increase the adsorption effect on the cardboard, the opening of the air inlet pipe is an inverted cone shape to increase the coverage area of ​​the air inlet pipe on the suction hole 21.

[0021] Furthermore, based on the above structure, the frame 1 is provided with several auxiliary belts 7 located between two adjacent conveyor belts 2. The width of the auxiliary belts 7 is smaller than the width of the conveyor belts 2. Specifically, the frame 1 is provided with several second mounting plates 71 located between two adjacent first mounting plates 22. A second pulley 72 is rotatably mounted on the second mounting plate 71. The auxiliary belts 7 are wound around the second pulley 72 and the drive shaft 6. When the drive shaft 6 drives the conveyor belts 2 to move, it drives the several auxiliary belts 7 to move synchronously. The auxiliary belts 7 increase the contact area with the cardboard without increasing the number of conveyor belts 2, thereby enhancing the stability when conveying the cardboard.

[0022] In addition, based on the above structure, two mounting rods 8 perpendicular to the conveying direction of the conveyor belt 2 are fixedly installed on the frame 1. The first mounting plate 22 and the second mounting plate 71 are respectively fixedly connected to the first mounting foot 24 and the second mounting foot 73, which are slidably disposed on the mounting rods 8. The first mounting foot 24 and the second mounting foot 73 are screwed with fastening bolts 9 that abut against the mounting rods 8. After loosening the fastening bolts 9, the position of the first mounting plate 22 and the second mounting plate 71 is adjusted by sliding the first mounting foot 24 and the second mounting foot 73 on the mounting rods 8, thereby adjusting the position of the conveyor belt 2 and the auxiliary belt 7 in the direction perpendicular to the conveying direction, so as to make the conveyor belt 2 accurately aligned with the opening of the air inlet pipe 53.

[0023] In addition, based on the above structure, the frame 1 is provided with two guide plates 10 located on both sides of the conveyor belt 2 and parallel to the conveyor belt 2. When the cardboard is placed on the conveyor belt 2 and conveyed with the conveyor belt 2, the two guide plates 10 are located on both sides of the cardboard and play a guiding role for the cardboard in the conveying process, preventing the cardboard from deviating during the conveying process and ensuring the stability of the cardboard during the conveying process.

[0024] In addition, based on the above structure, two support rods 11 perpendicular to the conveying direction of the conveyor belt 2 are fixedly installed on the frame 1. Two adjusting plates 12 are respectively located on one side of the two guide plates 10 on the support rods 11. The guide plates 10 are set on the adjusting plates 12. A drive screw 13 is rotatably installed on the frame 1 and is driven by a second motor 14 installed on the frame 1. The two adjusting plates 12 are respectively screwed onto two sections of oppositely oriented threads on the drive screw 13. The second motor 14 drives the drive screw 13 to rotate. The drive screw 13 simultaneously drives the two adjusting plates 12 to slide towards or away from each other on the support rods 11 through the two sections of oppositely oriented threads, thereby adjusting the distance between the two guide plates 10 to adapt to the conveying of cardboard of different widths.

[0025] Furthermore, based on the above structure, the adjusting plate 12 is composed of a fixed plate 101 and a movable plate 102. The fixed plate 101 is fixedly mounted on the adjusting plate 12. The adjusting plate 12 has an adjusting groove 121 parallel to the conveying direction of the conveyor belt 2. Several adjusting bolts 1021 passing through the adjusting groove 121 are fixedly connected to the movable plate 102. After passing through the adjusting groove 121, the adjusting bolts 1021 are screwed with adjusting nuts 1022 that are tightly pressed against the adjusting plate 12. Loosening the adjusting nuts 1022 allows the adjusting bolts 1021 to slide in the adjusting groove 121, thereby adjusting the position of the movable plate 102 relative to the fixed plate 101, and thus adjusting the overall length of the guide plate 10 in the conveying direction to adapt to the conveying of cardboard of different lengths.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
