Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box gluing equipment, and in particular to a cardboard box shaping and gluing device. Background Technology

[0002] To enhance the stability and load-bearing capacity of cardboard boxes, adhesive is typically applied to the surface of the cardboard. Adhesive application ensures that all parts of the box fit together tightly, thereby improving the overall strength and load-bearing capacity of the box.

[0003] In related technologies, dispensing machines are generally used to apply glue to key parts of cardboard boxes. Dispensing machines can save on glue costs while ensuring the boxes are bonded together. A dispensing machine typically consists of a base, a support frame, and a dispensing mechanism. By controlling the movement of the dispensing head within the mechanism, the machine applies glue to multiple key parts of the cardboard box.

[0004] However, due to the large size of some corrugated cardboard, the dispensing head of the dispensing machine needs to move a long distance to dispense glue to key areas, resulting in excessively long dispensing time for individual boards and thus affecting the overall dispensing efficiency. Summary of the Invention

[0005] In view of this, the present application provides a carton shaping and gluing device. Specifically, it adopts a telescopic gluing frame structure. Through the coordinated contraction of the angled hollow tube and the corrugated tube, as well as the hollow steel tube and the corrugated tube, the distance between the gluing syringes can be adjusted proportionally. In conjunction with the locking mechanism, the frame size can be quickly fixed to realize the function of gluing simultaneously using multiple gluing syringes.

[0006] To address the aforementioned technical problems, this application provides the following technical solutions:

[0009] The irregular column has an L-shaped cross-section, its bottom is fixedly connected to the end of the XY axis moving platform, and its top is fixedly provided with a support plate perpendicular to the horizontal plane.

[0010] The driving mechanism includes a hydraulic cylinder vertically disposed on the working surface of the support plate. The hydraulic cylinder is located above the XY axis moving platform.

[0011] The glued frame is formed by four hollow steel pipes and corrugated pipes connected alternately to form a rectangular frame, and adjacent hollow steel pipes are flexibly connected by the corrugated pipes.

[0012] Two beveled hollow tubes are arranged crosswise above the glue dispensing frame. The two tubes are connected to the glue cup injection port through the intersection point. The four ends of the two beveled hollow tubes are connected to the top of the hollow steel pipe. The axis of the two beveled hollow tubes coincides with the bevel line of the glue dispensing frame. A corrugated pipe is provided between each beveled hollow tube.

[0013] The locking mechanism includes a telescopic rod and a fixed tube connected to the top of the hollow steel tube. The axes of the two coincide with the oblique line of the glue-dispensing frame and are located below one of the oblique hollow tubes. The telescopic rod slides inside the fixed tube, and the fixed tube is externally threaded with a locking handle.

[0014] A dispensing syringe is disposed at the bottom of the hollow steel tube and communicates with it. The dispensing syringe is used to perform dispensing treatment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-3As shown in the embodiment of this application, the carton shaping and gluing device includes an XY-axis moving platform 100, a shaped column 200, a drive mechanism, a dispensing frame, an angled hollow tube 600, a locking mechanism, and a dispensing syringe 900. The XY-axis moving platform 100 is a platform that achieves precise movement in both the X and Y axes. Its axis couplings can be used to connect servo motors for automatic adjustment or directly connect to a rotating disk for manual adjustment. A shaped column with an L-shaped cross-section is fixedly installed at the end of the XY-axis moving platform 100. Specifically, the bottom of the shaped column is fixedly connected to the end of the XY-axis moving platform 100, and a support plate 210 is fixedly installed at the top of the shaped column. The working surface of the support plate 210 is perpendicular to the horizontal plane.

[0030] The main body of the drive structure is a hydraulic cylinder 220 arranged vertically. The hydraulic cylinder 220 is fixedly mounted on the working surface of the support plate 210, and the piston rod of the hydraulic cylinder 220 can move vertically. Furthermore, a cup clamp is fixedly mounted on the piston rod of the hydraulic cylinder 220, and a glue cup 300 for holding glue is fixedly mounted inside the cup clamp. The glue cup 300 is in an inverted state under the fixing action of the cup clamp, that is, the glue inlet of the glue cup 300 is vertically downward.

[0031] In this embodiment, the adhesive-dispensing frame is composed of four hollow steel pipes 400 and corrugated pipes 500. The hollow steel pipes 400 and corrugated pipes 500 are staggered, meaning that adjacent hollow steel pipes 400 are connected by corrugated pipes 500, which can be made of elastic rubber. The adhesive-dispensing frame has an overall rectangular frame structure, and the multiple hollow steel pipes 400 and corrugated pipes 500 are interconnected.

[0032] like Figure 2 and Figure 3 As shown, two intersecting, angled hollow tubes 600 are arranged above the dispensing frame. The intersection of the two intersecting angled hollow tubes 600 is connected to and communicates with the dispensing port of the glue cup 300, allowing the glue in the glue cup 300 to flow into the angled hollow tubes 600 by gravity. The axes of the two angled hollow tubes 600 coincide with the angled lines of the dispensing frame, and the bottoms of the two angled hollow tubes 600 are connected to and communicate with the hollow steel tube 400 of the dispensing frame. Therefore, the glue in the glue cup 300 can gradually flow into the dispensing frame through the angled hollow tubes 600. In addition, a corrugated tube 500 is provided between each angled hollow tube 600.

[0033] By installing corrugated pipes 500 between adjacent hollow steel pipes 400, and connecting the angled hollow pipes 600 via corrugated pipes 500, the glue dispensing frame can be expanded or reduced along the extension direction of the angled hollow pipes 600. Simultaneously, glue dispensing syringes 900 are located at and connected to the bottom of the hollow steel pipes 400. Therefore, when the area of ​​the glue dispensing frame expands or shrinks, the distance between the multiple glue dispensing syringes 900 can expand or shrink proportionally, thereby enabling glue dispensing onto corrugated cardboard of different sizes.

[0034] Continue as Figure 3 As shown, the locking mechanism consists of a fixed tube 800 and a telescopic rod 700 sleeved inside the fixed tube 800. The fixed tube 800 and the telescopic rod 700 are fixedly connected to the top surface of the hollow steel tube 400 at the corner of the dispensing frame. Both the fixed tube 800 and the telescopic rod 700 are located below the angled hollow tube 600, and the line connecting their axes is parallel to the axis of the angled hollow tube 600. A locking handle 810 is threaded onto the fixed tube 800. When the dispensing frame expands or shrinks to a preset size along the direction of the angled hollow tube 600, the locking handle 810 can be used to fix the telescopic rod 700 relative to the fixed tube 800, thereby achieving the purpose of locking the size of the dispensing frame.

[0035] The working principle and process of the carton shaping and gluing device provided in the embodiments of this application are described below.

[0036] First, the corrugated cardboard to be glued is placed on the working surface of the XY-axis working platform. Then, the hydraulic cylinder 220 is activated so that its piston rod drives the glue cup 300, the angled hollow tube 600, and the glue dispensing frame downwards, and glue is applied to the surface of the corrugated cardboard through the glue dispensing syringe 900. The glue dispensing process using the glue dispensing syringe 900 can be carried out in a conventional manner, which will not be described in detail in this embodiment.

[0037] When it's necessary to change the size of the dispensing frame to apply glue to corrugated cardboard of different sizes, the beveled hollow tube 600 can be manually stretched along its length, causing the connected corrugated tube 500 to elastically deform. Simultaneously, since the beveled hollow tube 600 and the hollow steel tube 400 of the dispensing frame are fixedly connected, the corrugated tube 500 between the hollow steel tubes 400 will also elastically deform, expanding the side length of the dispensing frame and thus adjusting its size. Finally, by inserting the locking handle 810 into the fixing tube 800 and securing it to the telescopic rod 700, the size of the dispensing frame can be locked. This allows the dispensing frame to simultaneously apply glue to corrugated cardboard of different sizes via the dispensing syringe 900.

[0038] In some embodiments, a lid 310 is detachably mounted on the opening at the top of the glue cup 300, and a vent hole is provided on the top of the lid 310. The detachable lid 310 facilitates quick and easy replenishment of glue into the glue cup 300, and also makes it easy to clean the inner cavity of the glue cup 300. The vent hole balances the internal and external air pressure of the glue cup 300, preventing problems with glue dispensing due to negative pressure.

[0039] In some embodiments, the corrugated pipe 500 is made of silicone rubber, with a corrugated wall and an inner diameter matching that of the hollow steel pipe 400 and the angled hollow pipe 600. The silicone rubber corrugated pipe 500 combines elasticity and corrosion resistance, enabling it to withstand long-term contact with adhesives. The annular corrugated structure provides axial expansion and contraction while ensuring the radial stiffness of the corrugated pipe 500. Furthermore, the matching inner diameters of all three components ensure cross-sectional consistency of the adhesive during flow, preventing adhesive buildup due to sudden changes in local flow velocity.

[0040] In some embodiments, the end of the locking handle 810 is provided with a rubber anti-slip layer, which forms a frictional lock with the outer wall of the telescopic rod 700 when tightened. The rubber anti-slip layer is designed to increase grip friction, thereby preventing slippage during manual operation. The progressive friction lock allows for stepless adjustment, avoiding the positioning accuracy loss caused by mechanical latches.

[0041] In some embodiments, a pressure sensor is provided at the end of the piston rod of the hydraulic cylinder 220, and the pressure sensor signal is connected to the control system of the XY axis moving platform 100. This allows for monitoring of the dispensing pressure via the pressure sensor and enables automatic compensation of the height position of the glue cup 300.

[0042] In some embodiments, the bottom of the hollow steel pipe 400 is provided with a plurality of dispensing syringes 900 arranged in a matrix, which enables simultaneous dispensing of adhesive at multiple points per unit area. Furthermore, the dispensing syringes 900 can automatically adjust proportionally to follow the dispensing border, thereby ensuring the uniformity of the adhesive dot distribution.
