Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, specifically to a corrugated paper positioning and guiding adjustment device for a gluing machine. Background Technology

[0002] The gluing machine is a key piece of equipment in the corrugated cardboard box production process. It is mainly used to firmly bond the overlapping edges of the die-cut corrugated cardboard (semi-finished cardboard box) through processes such as gluing, folding, and pressing, so as to form a complete cardboard box. When gluing the cardboard, the overlapping edges of the cardboard must be accurately aligned. If the overlap occurs during transportation, it will lead to misalignment of the glue, resulting in quality problems such as "exposed edges" and "crooked boxes", which will affect the sealing and load-bearing capacity of the cardboard box.

[0003] To prevent deviation during corrugated paper conveying, positioning guides are generally installed on both sides of the conveying path to limit the lateral displacement of the corrugated paperboard. However, existing positioning guides are generally in direct rigid contact with the edges of the corrugated paper, which can easily cause the edges of the paperboard to fray, crush, or scratch during high-speed conveying, especially for thin or high-strength corrugated paper. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated paper positioning and guiding adjustment device for a gluing machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated paper positioning and guiding adjustment device for a gluing machine, comprising a frame, a bidirectional lead screw, positioning guide components, and a pulse air source. Fasteners are evenly distributed on both sides of the bottom of the frame. A bidirectional lead screw is provided at the top of the inside of the frame, and driving blocks are sleeved at both ends of the bidirectional lead screw. A sleeve is provided at the bottom of each driving block, and a positioning guide component is provided below each sleeve. A drive motor is fixed at the top of one side of the frame, and the output end of the drive motor is connected to the bidirectional lead screw. An air chamber is opened inside each positioning guide component, and air guide holes are distributed on the surface of the positioning guide component. An air inlet is provided at the top of the positioning guide component, and a pulse air source is connected to the air inlet through an air guide pipe.

[0006] Preferably, a limit rod is provided at the top of the inside of the frame, and the top of each drive block is movably connected to the limit rod through a limit sleeve.

[0007] Preferably, all the positioning guides are arc-shaped, and one side of each positioning guide is provided with a wear-resistant layer, which is made of polytetrafluoroethylene composite material.

[0008] Preferably, a telescopic rod is provided on one side of the inside of the sleeve, and the telescopic rod extends out of the bottom of the sleeve. A mounting part is provided on one side of the positioning guide, and the bottom end of the telescopic rod is fixedly connected to the mounting part by a fixing bolt.

[0009] Preferably, a rack is provided on one side of each telescopic rod, and a gear that meshes with the rack is provided at one end inside each sleeve.

[0010] Preferably, each sleeve is provided with a knob on its outer side, and each knob is connected to a gear via a rotating shaft.

[0011] Preferably, a guide block is provided on one side of the telescopic rod, and a guide groove matching the guide block is provided on one side of the inside of the sleeve.

[0012] Preferably, the air guide holes are all distributed on the surface of the positioning guide, and the air guide holes are all connected to the air cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This corrugated paper positioning and guiding adjustment device for a gluing machine is equipped with a frame, a bidirectional lead screw, drive blocks, a drive motor, positioning guide components, an air chamber, air guide holes, an air guide pipe, and a pulse air source. The frame is mounted above the corrugated paper conveyor belt of the gluing machine. The positioning guide components are located on both sides of the corrugated paper conveying path to position and guide the corrugated paper. The drive motor drives the bidirectional lead screw to rotate, causing the drive blocks to move closer or further apart. Thus, the position of the positioning guide components can be adjusted according to the width of the corrugated paper. The positioning guide components are arc-shaped. The structure increases the contact area with the edge of the corrugated paper, disperses the contact pressure, and avoids the crushing or wear of the corrugated paper edge caused by local stress concentration due to traditional flat baffles. In addition, the positioning guide is equipped with an air cavity inside, and the surface of the positioning guide is evenly opened with air guide holes connected to the air cavity. By introducing gas into the air cavity and blowing out the air through the air guide holes, an air film can be formed between the positioning guide and the edge of the corrugated paper, which can significantly reduce frictional resistance and avoid wear and fuzzing of the corrugated paper edge caused by friction. It is especially effective in protecting thin or low-strength corrugated paper. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 An embodiment of this utility model provides a corrugated paper positioning and guiding adjustment device for a gluing machine, comprising a frame 1, a bidirectional lead screw 2, a positioning guide 5, and a pulse air source 19. Fasteners 9 are evenly distributed on both sides of the bottom of the frame 1. A bidirectional lead screw 2 is provided at the top inside the frame 1, and a driving block 3 is sleeved at both ends of the bidirectional lead screw 2. A sleeve 7 is provided at the bottom end of the driving block 3, and a positioning guide 5 is provided below the sleeve 7.

[0023] In this embodiment of the application, the frame 1 is fixed above the corrugated paper conveyor belt of the gluing machine by fasteners 9 on both sides of the bottom, ensuring that the positioning guides 5 are symmetrically distributed on both sides of the corrugated paper conveying path, and the two sets of positioning guides 5 maintain a preset distance in the initial state.

[0024] A drive motor 4 is fixed at the top of one side of the frame 1, and the output end of the drive motor 4 is connected to the bidirectional lead screw 2;

[0025] According to the width specifications of the corrugated paper to be processed, start the drive motor 4. Its output end drives the bidirectional lead screw 2 to rotate at the top of the machine frame 1. When the bidirectional lead screw 2 rotates, the drive blocks 3 at both ends move towards or away from each other along the lead screw. Through the sleeve 7, the positioning guide 5 at the bottom moves closer or further apart until the distance matching the width of the corrugated paper is reached, and then the drive motor 4 stops working.

[0026] A limit rod 6 is provided at the top of the inside of the frame 1. The top of the drive block 3 is movably connected to the limit rod 6 through a limit sleeve, which guides and limits the movement of the drive block 3.

[0027] The positioning guides 5 are all arc-shaped. After the corrugated paper enters the conveying path, the positioning guides 5 with arc-shaped structures on both sides constrain its lateral position through curved surfaces, disperse the contact pressure, and each side of the positioning guide 5 is provided with a wear-resistant layer 17. The wear-resistant layer 17 is made of polytetrafluoroethylene composite material, which further reduces the wear on the edge of the corrugated paper.

[0028] The positioning guide 5 has an air chamber 15 inside, and air guide holes 16 are distributed on the surface of the positioning guide 5. An air inlet 14 is provided on the top of the positioning guide 5, and a pulse air source 19 is connected to the air inlet 14 through an air guide pipe 18.

[0029] The air pump is a pulse air source 19, which consists of an air pump, a solenoid valve, and a timing controller. The air pump is responsible for providing continuous compressed air. The solenoid valve is triggered by a signal from the PLC control system and quickly switches on and off states at a preset frequency, converting the continuous airflow output by the air pump into intermittent pulse airflow. The timing controller precisely controls the duty cycle of the pulse to ensure that the air cushion pressure is stable within an appropriate range.

[0030] By activating the pulse air source 19, compressed gas enters the air chamber 15 inside the positioning guide 5 through the air inlet 14 via the air guide pipe 18, and is ejected through the air guide holes 16 distributed on the surface.

[0031] The airflow ejected from the air vent 16 forms an air film between the positioning guide 5 and the edge of the corrugated paper, reducing frictional resistance. Combined with the wear-resistant layer 17, it further reduces wear. During the conveying process, the arc-shaped positioning guide 5 corrects the slight deviation of the corrugated paper through curved surface guidance. The pulse air source 19 continuously provides airflow to maintain the stability of the air film. The structure of the bidirectional screw 2 and the telescopic rod 8 ensures the stability of the positioning parameters, realizing the precise positioning and guidance adjustment and smooth conveying of the corrugated paper.

[0032] One side of the sleeve 7 is provided with a telescopic rod 8, and the telescopic rod 8 extends out of the bottom of the sleeve 7. One side of the positioning guide 5 is provided with a mounting part 10, and the bottom end of the telescopic rod 8 is fixedly connected to the mounting part 10 by a fixing bolt 11.

[0033] Each side of the telescopic rod 8 is provided with a rack 22, and one end of the sleeve 7 is provided with a gear 13 that meshes with the rack 22.

[0034] A knob 12 is provided on the outer side of each sleeve 7, and each knob 12 is connected to the gear 13 through a rotating shaft;

[0035] To accommodate corrugated paper of different thicknesses, the knob 12 on the outside of the sleeve 7 can be rotated to drive the internal gear 13 to rotate through the shaft. The gear 13 meshes with the rack 22 on one side of the telescopic rod 8, allowing the telescopic rod 8 to extend and retract up and down, thereby adjusting the height of the positioning guide 5. After adjustment, the telescopic rod 8 is locked to the mounting part 10 of the positioning guide 5 by the fixing bolt 11.

[0036] A guide block 21 is provided on one side of the telescopic rod 8, and a guide groove 20 matching the guide block 21 is provided on one side of the sleeve 7, so that the telescopic rod 8 can be raised and lowered more smoothly.

[0037] The external design of knob 12 makes it easy for operators to get started quickly, and height adjustment can be completed without professional tools. Combined with the lateral adjustment of the bidirectional lead screw 2, a two-dimensional adjustment system of "lateral spacing and longitudinal height" is formed, so that a single set of positioning guide 5 can cover the processing needs of corrugated paper of various specifications, and significantly shorten the parameter debugging time during production changeover.

[0038] The specific model and specifications of the drive motor 4 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0039] Working Principle: In this embodiment, the frame 1 is fixed above the corrugated paper conveyor belt of the gluing machine by fasteners 9 on both sides of the bottom, ensuring that the positioning guides 5 are symmetrically distributed on both sides of the corrugated paper conveying path. In the initial state, the two sets of positioning guides 5 maintain a preset distance. According to the width specification of the corrugated paper to be processed, the drive motor 4 is started, and its output end drives the bidirectional lead screw 2 to rotate at the top inside the frame 1. At the same time, the drive block 3 slides along the limit rod 6 through the top limit sleeve to ensure stable movement direction. When the bidirectional lead screw 2 rotates, the drive blocks 3 at both ends move towards or away from each other along the lead screw, and through the sleeve 7, they synchronously drive the bottom positioning guides 5 to move closer or further apart until the distance matching the width of the corrugated paper is reached. Then the drive motor 4 stops working. If it is necessary to adapt to corrugated paper of different thicknesses, rotate the knob 12 on the outside of the sleeve 7, and drive the internal gear 13 to rotate through the rotating shaft. The gear 13 meshes with the rack 22 on one side of the telescopic rod 8, so that the telescopic rod 8 moves along the sleeve 7. The internal guide groove 20, in conjunction with the guide block 21, slides up and down to adjust the height of the positioning guide 5. After adjustment, the telescopic rod 8 is locked to the mounting part 10 of the positioning guide 5 by the fixing bolt 11. The pulse air source 19 is activated, and compressed gas enters the air chamber 15 inside the positioning guide 5 through the air inlet 14 via the air pipe 18, and is ejected through the air guide holes 16 distributed on the surface. After the corrugated paper enters the conveying path, the positioning guide 5 with its arc-shaped structure on both sides constrains its lateral position through the curved surface, dispersing the contact pressure. At the same time, the airflow ejected from the air guide holes 16 forms an air film between the positioning guide 5 and the edge of the corrugated paper, reducing frictional resistance. Combined with the wear-resistant layer 17, wear is further reduced. During the conveying process, the arc-shaped positioning guide 5 guides and corrects the slight deviation of the corrugated paper through the curved surface. The pulse air source 19 continuously provides airflow to maintain the stability of the air film. The structure of the bidirectional screw 2 and the telescopic rod 8 ensures the stability of the positioning parameters, realizing the precise positioning and guiding adjustment and smooth conveying of the corrugated paper.
