Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a pressing and gluing machine for cartons. Background Art

[0002] In the cardboard manufacturing process, applying glue to both ends is an essential step. Subsequently, professional pressing and gluing equipment is required to precisely press the cardboard to complete the assembly process of the cardboard.

[0003] The existing pressing and gluing machines generally adopt the method of driving the pressing wheel to descend by an electric telescopic rod, ensuring that the pressing wheel precisely presses on the glue-applied part of the cardboard, and realizing efficient pressing operation along with the continuous transmission of the cardboard. Although such equipment shows a certain degree of applicability in the cardboard pressing task, some problems still emerge in practical applications. First of all, during the pressing process of the cardboard, excessive glue application or uneven pressure distribution easily causes the glue to be squeezed out from the joint. These spilled glues will not only directly contaminate the surface of the cardboard but also may interfere with the subsequent processing process. In response to this phenomenon, some existing equipment has added a scraping device to remove the spilled glue. However, due to the fast-curing characteristic of the glue, once it fails to be cleaned in time, a cured glue layer will form on the surface of the scraper, which undoubtedly increases the workload of manual cleaning, reduces the production efficiency, and may affect the normal function of the scraper in the long run. Content of the Utility Model

[0004] In view of this, the utility model provides a pressing and gluing machine for cartons, which can timely scrape off the spilled waste glue through a glue scraping component, not only avoiding the pollution of the cardboard by the spilled glue but also realizing the effective collection of the waste glue, being able to efficiently remove the waste glue liquid adhering to the inner wall of the glue scraping plate, greatly reducing the manual cleaning burden, softening the cured glue by heat to make it easy to clean, and further improving the self-maintenance ability of the equipment, solving the problem of the glue solidifying on the inner wall of the glue scraping plate.

[0005] To solve the above technical problems, the utility model provides a pressing and gluing machine for cartons, including a U-shaped frame and a pressing mechanism arranged in the middle of the U-shaped frame. The pressing mechanism includes an installation opening arranged in the middle of the upper surface of the U-shaped frame. An electric push rod is arranged in the installation opening. The lower end of the telescopic end of the electric push rod is provided with a fixing plate. The right end of the rear surface of the fixing plate is provided with a glue scraping component. The glue scraping component includes a glue scraping plate arranged at the right end of the rear surface of the fixing plate. The electric push rod is electrically connected to an external single-chip microcomputer.

[0006] A heating wire is arranged in a serpentine cavity arranged near the wall surface inside the glue scraping plate. The heating wire is electrically connected to an external single-chip microcomputer.

[0007] The rubber scraping assembly further includes an assembly port provided in the middle of the upper surface of the rubber scraping plate. An electric telescopic rod is provided in the assembly port. The lower end of the telescopic end of the electric telescopic rod is provided with a waste rubber scraping plate. The waste rubber scraping plate is arranged in cooperation with the inner cavity of the rubber scraping plate. The electric telescopic rod is electrically connected to an external single-chip microcomputer.

[0008] The pressing mechanism further includes sliding holes symmetrically arranged horizontally at the left and right ends of the fixed plate. Slide rods are slidably connected in the sliding holes. A connecting plate is provided at the lower end between the two slide rods. The lower surface of the connecting plate is provided with assembly plates symmetrically distributed horizontally. A pressing wheel is rotatably connected at the lower end between the two assembly plates. The pressing mechanism further includes springs symmetrically arranged horizontally between the lower surface of the fixed plate and the upper surface of the connecting plate at the left and right ends. The springs are respectively sleeved on the outer parts of the vertically adjacent slide rods.

[0009] A pressing plate is provided on the right side of the rear surface of the connecting plate. The lower surface of the pressing plate is at the same horizontal plane as the lowermost end of the pressing wheel.

[0010] Transversely symmetrically distributed mounting plates are provided at the left and right sides of the lower end of the U-shaped frame.

[0011] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0012] 1. The rubber scraping plate will move down synchronously with the downward movement of the fixed plate, so that the rubber scraping plate contacts the joint of the cardboard box. When the cardboard is pressed, the excess glue will be squeezed out from the joint, and the pre-deployed rubber scraping plate can timely scrape off the overflowing waste glue, which not only avoids the pollution of the cardboard by the glue overflow, but also realizes the effective collection of the waste glue. The external single-chip microcomputer regularly controls the operation of the electric telescopic rod to drive the waste rubber scraping plate to move down synchronously, efficiently removing the waste glue adhered to the inner wall of the rubber scraping plate, greatly reducing the manual cleaning burden.

[0013] 2. When the glue solidifies on the inner wall of the rubber scraping plate, the external single-chip microcomputer starts the heating wire to soften the solidified glue with heat, making it easy to clean, further improving the self-maintenance ability of the equipment and solving the problem of the glue solidifying on the inner wall of the rubber scraping plate.

[0014] 3. The pressing plate intervenes after the cardboard has completed the pressing and rubber scraping processes, applying auxiliary pressing to the cardboard to ensure that it maintains the ideal shape after pressing, and preventing the problem of pressing failure caused by the cardboard warping.

[0015] 4. The relevant staff fixes the shaped frame and its ancillary mechanisms to the designated carton processing site through the mounting plate, and then the relevant staff controls the electric push rod and the external conveyor belt to operate synchronously through the external single-chip computer. The external conveyor belt drives the cardboard coated with glue to move at a uniform speed. At the same time, the telescopic end of the electric push rod extends downward to drive the fixed plate, slide rod, connecting plate, assembly plate, pressing wheel, spring and scraper assembly to descend synchronously until the pressing wheel accurately touches and presses the gluing part of the cardboard. In this process, the elastic force of the spring is used to ensure that the cardboard pressing force is balanced and appropriate throughout the whole process, so that the joint of the carton is under uniform pressure, thereby achieving accurate and stable pressing of the joint, effectively preventing the deformation of the cardboard due to excessive pressure, and adjusting the stroke of the electric push rod through the external single-chip computer to meet the pressing requirements of cartons of different thicknesses.
