Description

Technical Field

[0001] The utility model relates to the technical field of a palm-closing machine, in particular to a gluing mechanism of a palm-closing machine. Background Art

[0002] The closing machine is used to close the packaging film material into a roll bag-shaped packaging material. The existing closing machine mainly includes a unwinding roller, a packaging film guide roller, a winding roller, etc. When the packaging film is closed, glue is applied to the hinged position of the packaging film after the closing through the glue coating mechanism, and finally the connecting column of the packaging film is bonded after the closing.

[0003] At present, when the glue storage cylinder in the gluing mechanism of the hand-held machine is replenished with glue, bubbles are easily generated inside the glue. If the bubbles are transported to the glue outlet of the gluing mechanism of the hand-held machine along with the glue, it is easy to cause uneven glue discharge from the gluing mechanism of the hand-held machine, thereby affecting the quality of the packaging film processed by the hand-held machine. Moreover, when the glue storage cylinder is replenished with glue, the glue liquid has a large viscosity and the glue liquid replenishment speed is slow, which affects the convenience and efficiency of the gluing mechanism of the hand-held machine.

[0004] Therefore, we propose a gluing mechanism for a palm-closing machine to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the above problems and proposes a gluing mechanism for a palm-closing machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the auxiliary mechanism includes an air pump fixedly connected to the outer wall of the rubber storage cylinder, the air inlet of the air pump is fixedly connected to a bent pipe, the lower surface of the partition is fixedly embedded with an exhaust one-way valve, the output end of the bent pipe passes through the upper surface of the rubber storage cylinder and is fixedly connected to the exhaust end of the exhaust one-way valve, and the output end of the air pump is fixedly connected to a rubber discharge assembly.

[0009] Preferably, the debinding assembly comprises an electric heating cylinder fixedly connected to the output end of the vacuum pump, the output end of the electric heating cylinder is fixedly connected to a hose, and the output end of the hose is fixedly connected to a control rod.

[0010] Preferably, a sponge recovery block is connected inside the arc-shaped rubber cover.

[0011] Preferably, a flow guide hopper is fixedly connected to the inner wall of the glue storage cylinder and the upper surface of the partition, and the bottom end of the flow guide hopper is located above the glue guide one-way valve.

[0012] Preferably, a threading hole matching with the touch switch is provided on the upper surface of the base.

[0013] Compared with the prior art, the utility model provides a gluing mechanism for a palm-closing machine, which has the following beneficial effects:

[0014] 1. The gluing mechanism of the hand-closing machine, through the provision of a glue guide one-way valve, an auxiliary mechanism and a touch-pressure switch, when there is less glue left in the glue storage tube, the glue in the glue storage tube is light and cannot squeeze the arc-shaped rubber cover and the touch-pressure switch, causing the prompt light and the vacuum pump circuit to be turned on. The prompt light is lit to remind the staff to replenish glue in time to avoid glue interruption, and the air in the glue can be discharged in time through the auxiliary mechanism to ensure that no bubbles are generated when the glue coating mechanism supplies glue, resulting in uneven glue coating. This mechanism enables the hand-closing machine's gluing mechanism to have the functions of glue replenishment reminder and glue bubble removal, which can not only ensure the continuity of the gluing mechanism of the hand-closing machine, but also ensure the uniformity of the glue coating, thereby improving the reliability of the use of the hand-closing machine's gluing mechanism.

[0015] 2. The glue coating mechanism of the closing machine is equipped with a glue discharge component. When the glue storage cylinder is replenished with glue, the pressure switch will firstly make the vacuum pump and the electric heating cylinder work. The air discharged by the vacuum pump is heated by the electric heating cylinder, and the hot air is then discharged into the glue barrel through the hose. The hot air flow can speed up the speed at which the glue flows into the glue storage cylinder. This mechanism can effectively improve the efficiency of the glue coating mechanism of the closing machine.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model enables the gluing mechanism of the palm-jointed machine to have the functions of glue replenishment reminder and glue bubble removal, which can not only ensure the continuity of glue coating of the palm-jointed machine gluing mechanism, but also ensure the uniformity of glue coating, thereby improving the reliability of the use of the palm-jointed machine gluing mechanism, and can also effectively improve the efficiency of glue replenishment of the palm-jointed machine gluing mechanism.

[0022] The inner wall of the rubber storage cylinder 4 is fixedly connected with a partition 12, and the upper surface of the partition 12 is fixedly connected with a rubber guiding one-way valve 13. The inner wall of the rubber storage cylinder 4 and the upper surface of the partition 12 are jointly fixedly connected with a flow guide hopper 17. The bottom end of the flow guide hopper 17 is located above the rubber guiding one-way valve 13. The flow guide hopper 17 can facilitate the glue to pass through the rubber guiding one-way valve 13. A threaded hole is opened on the upper surface of the rubber storage cylinder 4, and a sealing plug 14 is threadedly connected to the hole wall of the threaded hole. The outer wall of the rubber storage cylinder 4 is fixedly connected with an auxiliary mechanism 8 and a warning light 15.

[0023] The auxiliary mechanism 8 includes an air pump 81 fixedly connected to the outer wall of the glue storage cylinder 4, the air inlet of the air pump 81 is fixedly connected to a bent pipe 82, an exhaust one-way valve 83 is fixedly embedded on the lower surface of the partition 12, the output end of the bent pipe 82 passes through the upper surface of the glue storage cylinder 4, and is fixedly connected to the exhaust end of the exhaust one-way valve 83, the output end of the air pump 81 is fixedly connected to a glue discharge component 9, the glue discharge component 9 includes an electric heating cylinder 91 fixedly connected to the output end of the air pump 81, the output end of the electric heating cylinder 91 is fixedly connected to a hose 92, and the output end of the hose 92 is fixedly connected to a control rod 93. This mechanism enables the gluing mechanism of the palm-jointed machine to have the functions of reminding glue replenishment and evacuating bubbles from the glue liquid, which can not only ensure the continuity of the gluing of the palm-jointed machine gluing mechanism, but also ensure the uniformity of the gluing, thereby improving the reliability of the use of the palm-jointed machine gluing mechanism, and can also effectively improve the efficiency of glue replenishment of the palm-jointed machine gluing mechanism.

[0024] The upper surface of the base 3 is provided with a threading hole 18 that cooperates with the touch pressure switch 11.

In the case of uneven glue coating, the mechanism enables the gluing mechanism of the palm-jointed machine to have the function of reminding glue replenishment and removing glue bubbles, which can not only ensure the continuity of glue coating by the palm-jointed machine gluing mechanism, but also ensure the uniformity of glue coating, thereby improving the reliability of the use of the palm-jointed machine gluing mechanism. When the glue storage cylinder 4 is replenished with glue, the pressure switch 11 will firstly make the vacuum pump 81 and the electric heating cylinder 91 work, and the air discharged by the vacuum pump 81 is heated by the electric heating cylinder 91, and the hot air is then discharged into the glue barrel through the hose 92. The hot air flow can speed up the speed at which the glue flows into the glue storage cylinder 4. The mechanism can effectively improve the efficiency of glue replenishment of the gluing mechanism of the palm-jointed machine.
