[0002] Card laminating machines are mainly used to produce various cards, hang tags, business cards, etc., and to glue two sheets of cardboard together according to specific requirements; therefore, they are also called laminating machines. They are suitable for laminating and bonding various corrugated cardboard, cardboard, and printed paper, and are widely used in the carton industry.

[0003] In existing technologies, the problem of insufficient adhesion caused by sedimentation of adhesive after prolonged standing in card mounting machines is often addressed by heating or stirring. However, existing stirring devices mostly employ constant stirring, which requires manual starting or stopping of the motor. For example, patent CN204674102U discloses a fully automatic card mounting machine that uses a stirring motor to drive a stirring rod for stirring.

[0004] This invention aims to mitigate or at least alleviate such problems by providing a stirring device that can automatically start or stop. Utility Model Content

[0005] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides an adhesive mixing device for a card mounting machine, which has the advantage of automatic opening or closing.

[0006] To achieve the above objectives, this utility model provides an adhesive mixing device for a card mounting machine, comprising: an adhesive tank, an adhesive inlet extending through the side of the adhesive tank, an adhesive outlet extending through the bottom of the adhesive tank, a top cover detachably mounted on the top of the adhesive tank, a rotating shaft extending through the top cover, a stirring paddle fixedly mounted at the bottom of the rotating shaft, a motor detachably mounted on the top of the rotating shaft, the motor being fixedly connected to the top cover via a fixing post, a live wire and a neutral wire I connected to the side of the motor, an upper contact fixedly connected to the end of the neutral wire I, a bracket fixedly mounted on the top of the top cover, the neutral wire I resting on the bracket, a neutral wire II resting on the bracket, an upper contact also fixedly mounted at the end of the neutral wire II, a connecting rod extending through the top cover, a float fixedly mounted at the bottom of the connecting rod, and a conductive plate fixedly mounted on the top of the connecting rod, wherein the conductive plate can contact all the upper contacts when the float rises.

[0007] As a further improvement of this utility model, a connecting rod is fixedly installed on the bracket. The connecting rod is located below the upper contact. Two lower contacts are installed through the connecting rod. A battery is fixedly installed at the bottom of one of the lower contacts. Wires are fixedly installed at the bottom of the other lower contact and the battery. An indicator light is fixedly installed on the top surface of the top cover. Both wires are electrically connected to the indicator light. The conductive plate can descend with the float and simultaneously contact the two lower contacts.

[0008] As a further improvement of this utility model, a heating sleeve is fixedly provided on the outside of the glue container, and the heating sleeve can heat the glue in the glue container.

[0009] As a further improvement of this utility model, both the neutral wire 2 and the neutral wire 1 are wrapped with a rigid insulating shell.

[0010] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0011] This invention relates to a glue mixing device for a card mounting machine. Through a combination of a float, connecting rod, and conductive plate, the motor circuit can be switched on or off according to changes in the glue level in the container.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0022] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0023] In the embodiments, by Figure 1-2 Give, Figure 1 This is a schematic diagram of the glue mixing device of a card mounting machine according to the present invention. As can be seen from the figure, the motor can drive the stirring paddle to rotate and stir the glue in the tank. When the glue level is higher than the float, the float rises under the action of buoyancy and makes the conductive plate contact the upper contact, and the neutral wire one and neutral wire two are connected.

[0024] Figure 2 This is a schematic diagram of the structure at point A of this utility model. As can be seen from the figure, when the conductive plate descends and contacts the lower contact, the wires are connected to form a circuit, and the indicator light will light up.

[0025] A glue mixing device for a card mounting machine includes: a glue tank 1, with a glue inlet 2 extending through its side and a glue outlet 3 extending through its bottom; a top cover 8 detachably mounted on the top of the glue tank 1; a rotating shaft 51 extending through the top cover 8; a stirring paddle 5 fixedly mounted at the bottom of the rotating shaft 51; a motor 4 detachably mounted on the top of the rotating shaft 51; the motor 4 being fixedly connected to the top cover 8 via a fixing post 41; and a live wire 42 and a neutral wire 43 connected to the side of the motor 4. The top cover 8 has an upper contact 102 fixedly connected to its end. A bracket 10 is fixedly installed on the top of the top cover 8. The neutral wire 1 43 is laid on the bracket 10. The neutral wire 2 101 is also laid on the bracket 10. The upper contact 102 is also fixedly installed at the end of the neutral wire 2 101. A connecting rod 61 is also installed through the top cover 8. A float 6 is fixedly installed at the bottom of the connecting rod 61. A conductive plate 103 is fixedly installed at the top of the connecting rod 61. When the float 6 rises, the conductive plate 103 can touch all the upper contacts 102.

[0026] Neutral wire 1 is connected to the negative terminal of the external power supply, and live wire is connected to the positive terminal. When there is a large amount of glue in the glue container, and the liquid level exceeds the height of the float, the float moves the connecting rod and the conductive plate upward. When the conductive plate contacts the upper contact, neutral wires 1 and 2 form an electrical connection, and the circuit for the motor is connected. The motor can then start and drive the stirring paddle to stir the glue in the container. When a large amount of glue in the container is used, the glue level drops below the height of the float. At this point, the float moves the conductive plate downward, the circuit for the motor is disconnected, the motor stops rotating, and the stirring operation stops, thus saving energy.

[0027] In a preferred embodiment of this utility model, a connecting rod 104 is fixedly mounted on the bracket 10. The connecting rod 104 is located below the upper contact 102. Two lower contacts 108 are connected through the connecting rod 104. A battery 105 is fixedly mounted at the bottom of one of the lower contacts 108, and wires 106 are fixedly mounted at the bottom of both the other lower contact 108 and the battery 105. An indicator light 107 is fixedly mounted on the top surface of the top cover 8. Both wires 106 are electrically connected to the indicator light 107. The conductive plate 103 can descend with the float 6 and simultaneously contact the two lower contacts 108. When the liquid level drops below the height of the float, the float drives the conductive plate to descend. When the conductive plate contacts the two lower contacts, the circuit of the indicator light is connected, and the indicator light lights up, indicating that the amount of glue in the tank is insufficient. The operator can then begin to inject new glue into the tank.

[0028] In a preferred embodiment of this invention, a heating sleeve 7 is fixedly disposed on the outside of the glue container 1, and the heating sleeve 7 is capable of heating the glue inside the glue container 1. Using the heating sleeve to heat the glue inside the container maintains the viscosity of the glue, and can prevent the glue from solidifying, especially in cold weather.

[0029] In a preferred embodiment of this utility model, both neutral wire 2 101 and neutral wire 1 43 are encased in a rigid insulating shell. Encasing neutral wire 1 and neutral wire 2 in a rigid insulating shell ensures the rigidity of the two wires, preventing them from deforming when laid on the support, and facilitating more stable contact between the upper contact and the conductive plate.

[0030] In a preferred embodiment of this invention, the connecting rod 61, float 6, and conductive plate 103 are all hollow rigid plastic, and a conductive film is adhered to both the upper and lower surfaces of the conductive plate 103. Using hollow rigid plastic reduces the weight of the connecting rod, float, and conductive plate, ensuring that the buoyancy applied to the float by the adhesive is greater than the sum of the weights of the three components. This allows for more sensitive movement of the float and the conductive plate, ensuring the normal operation of the device.

[0031] In summary, this utility model provides a glue mixing device for a card mounting machine. Through the combination of a float, connecting rod, and conductive plate, the motor circuit can be switched on or off according to changes in the liquid level in the glue container. When the liquid level is below the float, the float descends, the motor circuit is disconnected, and mixing stops. When the liquid level is above the float, the motor circuit is connected, and mixing begins. This allows mixing to automatically stop when there is little glue in the container and mixing is no longer needed, saving energy. This utility model also includes an indicator light. When the liquid level is below the float, the conductive plate descends and contacts the lower contact, connecting the indicator light circuit and illuminating the light. At this point, glue can be added to the container, eliminating the need to constantly monitor the liquid level.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
