Description

Technical Field

[0001] This utility model relates to the field of glue extraction equipment technology, and in particular to an automatic glue extraction device for a high-strength cardboard laminating machine. Background Technology

[0002] Paperboard lamination is the process of forming composite paperboard material by using specific processes. In the field of paperboard lamination, high-strength paperboard lamination machines are key equipment, and automatic glue extraction devices, as an important component, directly affect the lamination quality.

[0003] Currently, in traditional automatic glue extraction devices, the glue tends to settle and separate during prolonged standing due to differences in the density of its components. This sedimentation and separation leads to uneven glue composition, affecting the lamination effect during subsequent processing. Furthermore, air bubbles are easily generated in the glue, which can cause defects such as holes and bulges in the laminated layer after application, thus impacting the overall performance of the product. Therefore, designing an automatic glue extraction device for a high-strength cardboard laminating machine is necessary to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic glue extraction device for a high-strength cardboard laminating machine. To address usage issues, it incorporates a stirring and defoaming component. By controlling the lifting and rotation of multiple stirring rods, the glue can be uniformly stirred to prevent sedimentation and stratification that could affect the lamination effect. Simultaneously, in conjunction with a defoaming net, the glue can be defoamed, ensuring both coating effectiveness and product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic glue-drawing device for a high-strength cardboard laminating machine includes a housing and an agitation and defoaming assembly. The agitation and defoaming assembly includes a motor mounted on the upper end of the housing. The inner top and inner bottom of the housing are rotatably connected to first rotating shafts. A rectangular connecting rod is fixedly connected between the two first rotating shafts. A circular lifting plate that can move up and down is provided inside the housing. A second rotating shaft is provided through the middle of the circular lifting plate. The second rotating shaft is rotatably connected to the circular lifting plate through a bearing. Multiple agitating rods are fixedly connected to the outer side of the second rotating shaft. A rectangular inner groove is vertically opened at the upper end of the second rotating shaft. Two semi-circular through slots are opened on the circular lifting plate. Defoaming nets are fixedly connected in both semi-circular through slots.

[0007] Preferably, a hydraulic telescopic rod is installed on the right side of the housing, and a lifting block is fixedly connected to the telescopic end of the hydraulic telescopic rod. A columnar connecting rod is fixedly connected to the lower end of the lifting block. The lower end of the columnar connecting rod passes through the upper end of the housing and is fixedly connected to the upper end of the circular lifting plate.

[0008] Preferably, the upper end of the first rotating shaft located above passes through the inner top of the housing and is fixedly connected to the output shaft of the motor.

[0009] Preferably, the rectangular connecting rod passes through the rectangular inner groove and is slidably connected to the inner wall of the rectangular inner groove.

[0010] Preferably, a gear pump is installed on the front side of the housing, the inlet pipe of the gear pump extends to the inner bottom of the housing, an arc-shaped heating plate is provided inside the inner wall of the housing, and a liquid level sensor is installed at the inner bottom of the housing.

[0011] Preferably, a controller is installed on the front side of the housing, and a material conveying pipe is provided at the upper end of the housing.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] An agitation and defoaming mechanism is installed. A motor drives a rectangular connecting rod to rotate, which in turn rotates multiple agitator rods, agitating the adhesive inside the shell. Simultaneously, a hydraulic telescopic rod controls a circular lifting plate, moving multiple agitator rods up and down to expand the agitation range. This effectively prevents the adhesive from settling and separating, ensuring the quality of the lamination process. Furthermore, as the circular lifting plate moves, it also raises and lowers a defoaming net, further defoaming the adhesive inside the shell. This ensures a good subsequent coating effect, effectively preventing defects such as holes and bulges in the composite layer, and guaranteeing product performance and quality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 An automatic glue extraction device for a high-strength cardboard laminating machine includes a housing 1 filled with an appropriate amount of glue to be used. A gear pump 14 is installed on the front side of the housing 1 (this is prior art). The inlet pipe of the gear pump 14 extends to the inner bottom of the housing 1. By starting the gear pump 14, the glue in the housing 1 can be extracted and delivered to the coating head through the outlet pipe of the gear pump 14 (a flow regulating valve, not shown, is provided at the outlet pipe to control the flow rate of the glue for fine adjustment) for glue application. An arc-shaped heating plate 15 is provided in the inner wall of the housing 1. The arc-shaped heating plate 15 is provided with heating wires to heat the glue and maintain it at an appropriate temperature to ensure the viscosity of the glue is stable, thereby facilitating subsequent glue extraction. A liquid level sensor 16 is installed at the inner bottom of the housing 1 to monitor the glue level in real time and prevent air intake when the liquid level is low. A controller 17 is installed on the front side of the housing 1, and a feed pipe 18 is provided at the upper end of the housing 1 to replenish the glue in the housing 1.

[0021] The system also includes a stirring and defoaming component, which includes a motor 2 mounted on the upper end of the housing 1. The inner top and inner bottom of the housing 1 are rotatably connected to a first rotating shaft 3. The upper end of the first rotating shaft 3 located at the top passes through the inner top of the housing 1 (a bearing is provided at the penetration point) and is fixedly connected to the output shaft of the motor 2. A rectangular connecting rod 4 is fixedly connected between the two first rotating shafts 3. A circular lifting plate 5 that can move up and down is provided inside the housing 1. A second rotating shaft 6 passes through the middle of the circular lifting plate 5. The second rotating shaft 6 is rotatably connected to the circular lifting plate 5 through a bearing (the bearing connection is sealed). Multiple stirring rods 7 are fixedly connected to the outside of the second rotating shaft 6. The multiple stirring rods 7 can stir and mix the glue in the housing 1 to ensure the overall uniformity of the glue, avoid its sedimentation and stratification, and ensure the effect of subsequent compounding operations. A rectangular inner groove 8 is vertically opened at the upper end of the second rotating shaft 6. The rectangular connecting rod 4 passes through the rectangular inner groove 8 and is slidably connected to the inner wall of the rectangular inner groove 8.

[0022] The circular lifting plate 5 has two semi-circular through slots 9, and each semi-circular through slot 9 is fixedly connected to a defoaming net 10. By controlling the lifting and lowering of the defoaming net 10, the glue in the housing 1 can be defoamed, ensuring the subsequent glue application effect. A hydraulic telescopic rod 11 is installed on the right side of the housing 1. A lifting block 12 is fixedly connected to the telescopic end of the hydraulic telescopic rod 11. A columnar connecting rod 13 is fixedly connected to the lower end of the lifting block 12. The lower end of the columnar connecting rod 13 passes through the upper end of the housing 1 and is fixedly connected to the upper end of the circular lifting plate 5.

[0023] In this utility model, when used for the first time, an appropriate amount of glue to be used is first filled into the housing 1 through the feed pipe 18. Then, the arc-shaped electric heating plate 15 is activated to heat up the glue in the housing 1 and maintain it at an appropriate temperature to ensure that the viscosity of the glue is stable, which is conducive to subsequent extraction. When it is necessary to extract the glue, the operator can activate the gear pump 14 and extract the glue from the bottom of the housing 1 through the liquid inlet pipe of the gear pump 14, and deliver the glue to the coating head for lamination.

[0024] Before each extraction of adhesive from the housing 1, the operator can start the motor 2, which drives the first rotating shaft 3 and the rectangular connecting rod 4 to rotate, causing the second rotating shaft 6 and multiple stirring rods 7 to rotate synchronously, thereby agitating and mixing the adhesive in the housing 1. At the same time, the hydraulic telescopic rod 11 is activated to move the lifting block 12 up and down, which in turn moves the circular lifting plate 5 up and down through the columnar connecting rod 13. When the circular lifting plate 5 moves, it can drive the second rotating shaft 6 and multiple stirring rods 7 to move up and down, thereby expanding the actual agitation range and further ensuring the overall uniformity of the adhesive, avoiding adhesive sedimentation and stratification that would affect the effect of subsequent lamination operations.

[0025] It is worth mentioning that during the up-and-down movement of the circular lifting plate 5, the two defoaming nets 10 fixedly connected to it will rise and fall accordingly, thereby defoaming the glue inside the shell 1, ensuring the subsequent glue application effect and guaranteeing the actual product quality.

[0026] It should be noted that the wiring of the motor 2, hydraulic telescopic rod 11, gear pump 14, arc-shaped electric heating plate 15 and liquid level sensor 16 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control, power supply method and wiring layout of the motor 2, hydraulic telescopic rod 11, gear pump 14, arc-shaped electric heating plate 15 and liquid level sensor 16 will not be explained in detail.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
