An automatic cardboard box adhesive applicator

Abstract

This invention discloses an automatic cardboard box gluing machine, comprising a frame, a cardboard box feeding mechanism, a conveyor belt, a guiding mechanism, a gluing mechanism, and a sensing mechanism. Stacks of cardboard boxes are fed into the cardboard box feeding mechanism. A first rotating roller pulls the bottommost cardboard box off to the base plate. A second rotating roller similarly conveys the cardboard boxes sequentially onto the conveyor belt. Guide wheels on the guiding mechanism roll and guide the upper surface of the cardboard boxes, serving both a guiding and flattening function. The sensing mechanism is equipped with two sensors, which respectively sense the position of the cardboard box entering and exiting the machine and the distance between the edge of the cardboard box and the inner side of the frame. The gluing machine on the gluing mechanism can be moved and adjusted. Based on the sensor readings, gluing is applied to a preset position on the cardboard box, with a few millimeters of clearance between the gluing point and one side of the cardboard box. This achieves automatic cardboard box feeding, conveying, and gluing processes, resulting in high gluing efficiency and ensuring uniform gluing positions.

Description

Technical Field

[0001] This invention belongs to the field of adhesive applicator technology, and particularly relates to an automatic adhesive applicator for cardboard boxes. Background Technology

[0002] During the production of paper boxes, adhesive needs to be applied to the pre-set connection points of the paper box to facilitate the subsequent folding and fixing of the paper box.

[0003] Currently, manually applying adhesive to cardboard boxes is clearly unsuitable for mass production. Firstly, it leads to worker fatigue and errors in adhesive application. Secondly, the work efficiency is low, failing to meet the requirements for mass production in terms of both precision and efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cardboard box gluing machine to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an automatic cardboard box adhesive applicator, comprising:

[0006] frame;

[0007] A cardboard box feeding mechanism is located at one end of the frame. Stacks of cardboard boxes are divided into individual cardboard boxes and conveyed sequentially within the cardboard box feeding mechanism.

[0008] A conveyor belt is driven and mounted on the frame. The conveyor belt is connected to the carton feeding mechanism and is used to receive and transport the cartons from the carton feeding mechanism.

[0009] A guiding mechanism, mounted on the frame and located above the conveyor belt, is used for rolling and conveying paper boxes.

[0010] An adhesive applicator is located at the other end of the frame and is used to apply adhesive to cardboard boxes conveyed on the conveyor belt.

[0011] A sensing mechanism is mounted on the frame and located between the guiding mechanism and the adhesive applicator. The sensing mechanism and the adhesive applicator are controlled and connected. The sensing mechanism is configured to identify the entry and exit positions of the cardboard box to control the adhesive applicator's application length on the cardboard box. The sensing mechanism can also identify the distance between the cardboard box and the inner side of the frame to adjust the distance between the adhesive applicator's application position on the cardboard box and one side of the cardboard box.

[0012] In a further embodiment of the present invention, the paper box feeding mechanism includes a base plate, a first rotating roller, side plates, a guide rod, a support frame, a positioning frame, and an adjusting rod. The guide rod is horizontally fixed on the frame, the adjusting rod is disposed on the guide rod, the side plates are fixed to the inner side of the adjusting rod and opposite to it, the support frame is fixed on the adjusting rod, the positioning frame is fixed to the inner side of the side plates and one end is fixed to the support frame, the base plate is fixed between the side plates and located at the bottom of the positioning frame, the first rotating roller is rotatably disposed between the side plates and close to one end of the frame, and the guide rod is also provided with a first fixing block and a second fixing block, on which are respectively fixed a first fixing block and a second fixing block. A first positioning rod and a second positioning rod are provided. A first roller is rotatably mounted on one end of the first positioning rod, and a second roller is rotatably mounted on one end of the second positioning rod. Stacked cardboard boxes are placed between the side plates and pass through the bottom of the positioning frame. The first roller provides rolling support at the bottom end of the stacked cardboard boxes, and the second roller rolls in cooperation with the end face of the stacked cardboard boxes. The first rotating roller rolls in cooperation with the lower surface of the bottommost cardboard box. The first rotating roller sequentially feeds the bottommost cardboard box piece by piece onto the base plate for orderly feeding. A second rotating roller is rotatably mounted on the other end of the adjusting rod. The second rotating roller is connected to the base plate and is used to guide and convey the cardboard boxes conveyed from the base plate.

[0013] In a further embodiment of the present invention, a third positioning rod is fixed on the positioning frame, and a fourth positioning rod is horizontally fixed between the third positioning rods, with a limit block fixed on the fourth positioning rod.

[0014] In a further embodiment of the present invention, the guiding mechanism further includes a third fixing block, which is fixed on the frame. A fifth positioning rod is fixed between the third fixing blocks. A fourth fixing block is fixed on the fifth positioning rod. A sixth positioning rod is connected to the fourth fixing block. A guide wheel is rotatably provided at the tail end of the sixth positioning rod. The guide wheel rolls and presses against the upper surface of the cardboard box on the conveyor belt.

[0015] In a further embodiment of the present invention, the sensing mechanism includes a first mounting frame, which is fixed on the frame. Two seventh positioning rods are mounted on the first mounting frame, and sensors are mounted on the seventh positioning rods. One sensor is used to sense the position of the paper box entering or leaving the machine, and the other sensor is used to sense the distance between the edge of the paper box and the inside of the machine frame.

[0016] In a further embodiment of the present invention, the adhesive applicator includes a second mounting frame and an adhesive applicator. The second mounting frame is fixed on the frame and has a slide rod and a rotatable lead screw. A handwheel is provided at one end of the lead screw. The adhesive applicator is slidably connected to the slide rod. The lead screw and the adhesive applicator are threadedly adjustable. By rotating the handwheel, the lead screw is rotated to adjust the movement of the adhesive applicator along the axial direction of the slide rod. The adhesive applicator is used to apply adhesive to the cardboard box to match the sensor.

[0017] The beneficial effects of this invention are:

[0018] Stacks of cardboard boxes are arranged in a stack within the cardboard box feeding mechanism, with both sides of the boxes adhering to the inner side panels. One end of the box passes through the bottom of the positioning frame. The first roller rolls in conjunction with the lower surface of the bottommost box. The first roller supports the bottom of the box and guides its movement, while the second roller supports one end of the box and also guides it, causing the stack of boxes to form an arc shape. The rotation of the first roller pulls the bottommost box out onto the base plate. The first and second rollers not only support and guide the boxes but also tilt them at an angle, with the outer side higher than the inner side, by lifting one side of the box. This prevents the boxes from shifting during feeding and improves feeding efficiency. The second roller also rotates, sequentially conveying the boxes onto the conveyor belt. The guiding mechanism... The rollers guide the upper surface of the cardboard box, serving both a guiding and flattening function. The sensing mechanism has two sensors: one detects the cardboard box's entry / exit position, and the other detects the distance between the cardboard box's edge and the inner side of the frame. During transport, if the cardboard box shifts or warps, the guiding mechanism ensures the sensors accurately detect its position. The adhesive applicator on the adhesive applicator is adjustable and applies adhesive at preset positions on the cardboard box based on sensor readings. The adhesive application point is a few millimeters away from one side of the cardboard box, thus achieving automatic feeding, conveying, and adhesive application of the cardboard box. This process is highly efficient and ensures consistent adhesive application. Attached Figure Description

[0033] A sensing mechanism 7 is disposed on the frame 1 and located between the guiding mechanism 5 and the adhesive applicator 6. The sensing mechanism 7 and the adhesive applicator 6 are controlled to be connected. The sensing mechanism 7 is configured with the adhesive applicator 6 to identify the entry and exit positions of the cardboard box 2 in order to control the adhesive applicator 6 to apply adhesive on the cardboard box 2. The sensing mechanism 7 can also identify the distance between the cardboard box 2 and the inner side of the frame 1 to adjust the distance between the adhesive applicator 6 and the side of the cardboard box 2.

[0034] In this embodiment, the paper box feeding mechanism 3 further includes a base plate 30, a first rotating roller 31, a side plate 32, a guide rod 33, a support frame 34, a positioning frame 35, and an adjusting rod 36.
