Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to cleaning devices. Background Technology

[0002] In modern industrial production and packaging, hot melt glue guns, with their efficient and convenient glue application characteristics, are used for glue application in product packaging and label areas. The hot melt glue gun nozzle outputs molten glue and sprays it precisely onto the area to be glued, facilitating the subsequent bonding and forming process of product packaging boxes and ensuring that the label can be firmly adhered to the product surface. This plays a key role in improving production efficiency and product packaging quality.

[0003] Currently, due to equipment malfunctions, maintenance, and routine upkeep, hot melt glue guns in packaging equipment may temporarily stop operating. When the hot melt glue gun stops, the high-temperature molten glue inside the gun will rapidly cool and solidify due to the drop in ambient temperature. This solidified glue easily clogs the nozzle of the hot melt glue gun. Once the nozzle is clogged, it will not only seriously affect the normal spraying operation of the hot melt glue gun, but also prevent the subsequent product packaging process from proceeding smoothly, leading to a series of problems such as production delays and increased defect rates.

[0004] Therefore, cleaning devices are urgently needed to solve the above problems. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] This embodiment provides a cleaning device, such as Figures 1-2As shown, this cleaning device is used to clean a hot melt glue gun. The hot melt glue gun includes a connector and a nozzle. Glue can be input into the hot melt glue gun through the connector, and the nozzle can output glue. The cleaning device includes a heating clamping mechanism 1 and an air supply mechanism. The heating clamping mechanism 1 includes a clamping assembly 11 and a heating assembly 12. The clamping assembly 11 includes a first clamping member 111 and a second clamping member 112. The hot melt glue gun can be clamped between the first clamping member 111 and the second clamping member 112. The second clamping member 112 can move relative to the first clamping member 111 and clamp the hot melt glue gun. The heating assembly 12 is disposed on the clamping assembly 11 and is used to heat the hot melt glue gun. The output end of the air supply mechanism is connected to the connector, and the air supply mechanism can supply positive pressure to the inside of the hot melt glue gun.

[0034] When cleaning a hot melt glue gun, the cleaning device first places the hot melt glue gun between the first clamp 111 and the second clamp 112. The second clamp 112 moves relative to the first clamp 111 to clamp the hot melt glue gun. Then, the heating component 12 heats the hot melt glue gun, melting the residual glue inside. After that, the output end of the air supply mechanism is connected to the connector of the hot melt glue gun, and the air supply mechanism supplies positive pressure to the inside of the hot melt glue gun. Under the action of positive pressure, the melted glue is discharged from the nozzle of the hot melt glue gun, thus achieving cleaning. This cleaning device can effectively remove residual glue from the hot melt glue gun, prevent the glue from solidifying and clogging the nozzle of the hot melt glue gun, extend the service life of the hot melt glue gun, and improve cleaning efficiency.

[0035] In this embodiment, the air supply mechanism is connected to the connector of the hot melt glue gun through a pipe and continuously supplies positive pressure to the inside of the hot melt glue gun. Positive pressure ensures that the hot melt glue is smoothly discharged from the gun head, greatly improving the smoothness of glue dispensing, avoiding cleaning interruptions or unevenness caused by poor glue dispensing, and improving cleaning quality.

[0036] like Figures 1-2 As shown, the heating clamping mechanism 1 also includes a handle 13. The first clamping member 111 includes a clamping part 1111, a connecting part 1112, and a supporting part 1113. The two ends of the connecting part 1112 are respectively connected to the clamping part 1111 and the supporting part 1113. The supporting part 1113 is provided with a through hole. One end of the handle 13 passes through the through hole and is rotatably connected to the supporting part 1113, and the other end is threadedly connected to the second clamping member 112. Rotating the handle 13 can drive the second clamping member 112 to move on the connecting part 1112, so that the distance between the clamping part 1111 and the second clamping member 112 is adjustable. This design allows the cleaning device to be adapted to hot melt glue guns of different sizes, greatly improving the versatility of the cleaning device, and is simple to operate, providing convenience for practical applications.

[0037] In this embodiment, a bearing is installed in the through hole of the support ear 1113. The inner wall of the through hole is connected to the outer ring of the bearing. One end of the handle 13 is engaged with the inner ring of the bearing. When the handle 13 rotates, the second clamping member 112 moves along the thread extension direction. Through the bearing connection, the handle 13 rotates smoothly, reducing the frictional resistance during rotation and making operation more effortless.

[0038] Specifically, the first clamping member 111 is constructed as a U-shaped structure, and the second clamping member 112 moves within the U-shaped structure, effectively ensuring the stability of the movement of the second clamping member 112 and making the operation process more reliable. The handle 13 passes through the through hole on the support lug 1113 and is threadedly connected to the second clamping member 112. The hot melt glue gun is placed in the area enclosed by the clamping part 1111, the connecting part 1112, and the second clamping member 112. By rotating the handle 13, the distance between the clamping part 1111 and the second clamping member 112 can be easily adjusted to clamp the hot melt glue gun, ensuring that the position of the hot melt glue gun is fixed during cleaning and other operations, thereby improving the working efficiency and reliability of the cleaning device.

[0039] In this embodiment, the first clamping member 111 includes two supporting ears 1113, both of which are connected to the connecting part 1112. Each supporting ear 1113 has a through hole. The clamping assembly 11 includes two handles 13. The two first ends of each handle 13 pass through the two through holes on the two supporting ears 1113 and are rotatably connected to them. The two second ends of each handle 13 are threadedly connected to the second clamping member 112. The design of the two handles 13 provides a more balanced and stable force when adjusting the position of the second clamping member 112 relative to the clamping part 1111. This ensures that the second clamping member 112 remains stable during movement, avoiding tilting or wobbling. This allows the clamping part 1111 and the second clamping member 112 to clamp the hot melt glue gun more accurately and firmly, enhancing the reliability of the clamping assembly 11's clamping operation.

[0040] like Figures 1-2 As shown, the heating assembly 12 includes a first heating element 121 and a second heating element 122. The first heating element 121 is disposed inside the first clamping member 111 and can heat the first clamping member 111. The second heating element 122 is disposed inside the second clamping member 112 and can heat the second clamping member 112. The first clamping member 111 and the second clamping member 112 can conduct heat to heat the hot melt glue gun. This dual-sided heating method makes the hot melt glue gun heat up more evenly and quickly, effectively improving the fluidity of the glue and facilitating the discharge of glue from the hot melt glue gun during cleaning, thus improving cleaning efficiency and effectiveness.

[0041] In this embodiment, both the first heating element 121 and the second heating element 122 are resistance heating tubes. Resistance heating tubes have high thermal efficiency, can quickly convert electrical energy into heat energy, and provide uniform heating, significantly shortening the heating time and improving work efficiency. In other embodiments, the first heating element 121 and the second heating element 122 can also be infrared heating tubes, electromagnetic heating plates, etc., and are not specifically limited here.

[0042] In this embodiment, the heating assembly 12 includes two first heating elements 121 and two second heating elements 122. Both first heating elements 121 are disposed inside the first clamping member 111, and both second heating elements 122 are disposed inside the second clamping member 112. In other embodiments, the number of first heating elements 121 can be three, four, or five, and the number of second heating elements 122 can be three, four, or five; no specific limitation is made here.

[0043] like Figures 1-2 As shown, the cleaning device also includes a power supply, a first relay (not shown), a heating start button 21, and a heating stop button 22. The power supply outputs current, and the first relay is electrically connected to the heating component 12. The power supply, heating start button 21, and heating stop button 22 are all electrically connected to the first relay. The heating start button 21 connects the first relay and the power supply to turn on the heating component 12, and the heating stop button 22 disconnects the first relay and the power supply to turn off the heating component 12. The power supply outputs current, which powers the heating component 12 via the first relay. Pressing the heating start button 21 quickly connects the first relay and the power supply, conveniently turning on the heating component 12 and heating the hot melt glue gun in time. When heating needs to be stopped, pressing the heating stop button 22 disconnects the first relay and the power supply, quickly turning off the heating component 12. This design makes the operation of turning the heating component 12 on and off simple, allowing for flexible adjustment according to the cleaning process, and improving the convenience and controllability of the cleaning operation.

[0044] Specifically, in this embodiment, the heating component 12, the power supply, the first relay, the heating start button 21, and the heating stop button 22 form an electrical circuit connected in series. When the heating start button 21 is pressed, the series circuit closes, and the current output from the power supply is transmitted sequentially through the first relay to the heating component 12. The heating component 12 then turns on after receiving power, thereby heating the hot melt glue gun held within it. When the heating stop button 22 is pressed, the series circuit immediately disconnects, cutting off the current transmission path from the power supply to the heating component 12. The heating component 12 shuts off due to the loss of power supply, stopping the heating of the hot melt glue gun.

[0045] In this embodiment, the cleaning device also includes a temperature detection element (not shown), which is used to detect the temperature of the clamping assembly 11. The temperature detection element monitors the temperature of the clamping assembly 11 in real time, ensuring that the hot melt glue gun clamped between the first clamping member 111 and the second clamping member 112 is at a suitable heating temperature. If the temperature is too high, the heating assembly 12 can be shut off in time to stop heating the hot melt glue gun, preventing damage due to overheating and affecting its performance and service life. If the temperature does not meet expectations, the heating assembly 12 continues to heat the hot melt glue gun, ensuring that the glue effectively melts and is discharged, improving the cleaning effect and enhancing the controllability of the cleaning operation.

[0046] In this embodiment, the temperature detection component is a resistance temperature detector (RTD). The RTD has high detection accuracy and can accurately measure the temperature of the clamping component 11, so as to keep track of the heating status of the hot melt glue gun, ensure that the heating temperature is appropriate, and improve the cleaning effect.

[0047] like Figures 1-2 As shown, the cleaning device also includes a temperature controller, which is electrically connected to a first relay. When the temperature detection element detects that the temperature of the clamping assembly 11 is greater than or equal to a preset temperature, it can send a first temperature signal. The temperature controller can receive the first temperature signal and close the first relay to shut down the heating assembly 12. The temperature detection element constantly monitors the temperature of the clamping assembly 11, and once it detects that the temperature has reached or exceeded the preset value, it immediately sends a first temperature signal. After receiving the signal, the temperature controller quickly closes the first relay, thereby shutting down the heating assembly 12. This design avoids overheating of the heating assembly 12 and prevents the hot melt glue gun from being damaged due to excessive temperature. At the same time, it reduces the risk of safety accidents caused by temperature runaway, ensures the personal safety of operators, and also realizes intelligent control of the heating process without the need for real-time manual monitoring, improving the efficiency and safety of cleaning operations.

[0048] Specifically, the heating component 12, power supply, first relay, heating start button 21, and heating stop button 22 form an electrical circuit connected in series, and the temperature controller is communicatively connected to the first relay. When the heating start button 21 is pressed, the series circuit closes, and the current output from the power supply is transmitted sequentially through the first relay to the heating component 12. After receiving electrical energy, the heating component 12 turns on, thereby heating the hot melt glue gun clamped therein. When the temperature sensor detects that the temperature of the clamping component 11 is greater than or equal to the preset temperature, it sends a first temperature signal. The temperature controller receives the first temperature signal and closes the first relay, disconnecting the series circuit and turning off the heating component 12.

[0049] In this embodiment, the first clamping member 111 is provided with a first mounting hole 1114, and the temperature sensing element is installed in the first mounting hole 1114. The first mounting hole 1114 provides a precise installation position for the temperature sensing element, ensuring that the temperature sensing element is fixed in position and not easily shaken, thus ensuring the stability of temperature detection. The temperature sensing element can directly and quickly obtain the temperature of the clamping component 11, greatly improving the timeliness and accuracy of temperature detection, so as to make timely and effective control over the heating component 12 and improve the cleaning efficiency of the hot melt glue gun.

[0050] In other embodiments, the second clamping member 112 is provided with a second mounting hole (not shown), and the temperature sensing element is installed in the second mounting hole. The second mounting hole provides a stable mounting position for the temperature sensing element, ensuring that the temperature sensing element will not loosen or shift during the cleaning process, ensuring the stability of data detection, timely and accurate temperature information, avoiding damage to the hot melt glue gun due to abnormal temperature, and helping to improve the cleaning effect.

[0051] In some embodiments, the cleaning device includes two temperature sensors, which are respectively disposed in the first mounting hole 1114 and the second mounting hole, and respectively detect the temperature of the first clamping member 111 and the second clamping member 112, so as to accurately grasp the temperature status of the first clamping member 111 and the second clamping member 112 in real time and detect temperature abnormalities in a timely manner.

[0052] In this embodiment, the cleaning device also includes a cooling mechanism for cooling the heated clamping mechanism 1. On the one hand, rapidly reducing the temperature of the heated clamping mechanism 1 allows the cleaning device to proceed to the next cleaning cycle more quickly, improving cleaning efficiency, preventing deformation of the clamping component 11, and extending the service life of the clamping component 11. On the other hand, when the temperature of the clamping component 11 is too high, the cooling mechanism can quickly cool the clamping component 11, preventing damage to the hot melt glue gun due to prolonged high-temperature heating.

[0053] In this embodiment, the cooling mechanism is located below the heating clamping mechanism 1, which allows the cooling mechanism to come into contact with the heat emitted by the heating clamping mechanism 1 as soon as possible, quickly remove the residual heat, and greatly improve the cooling efficiency.

[0054] In other embodiments, the cooling mechanism can also be arranged around the heating clamping mechanism 1. The surrounding layout allows the cooling mechanism to cool the heating clamping mechanism 1 from multiple directions simultaneously. Compared with a single location arrangement, the heat exchange is more complete and the heat dissipation is more uniform, effectively avoiding the deformation of the component due to excessive local temperature. The location of the cooling mechanism is not specifically limited here.

[0055] In this embodiment, the cooling mechanism is a fan. The fan accelerates the airflow around the heating clamping mechanism 1 with high-speed airflow, quickly removes heat, and reduces the temperature of the clamping component 11 and the hot melt glue gun in time, so as to avoid damage caused by overheating.

[0056] In other embodiments, the cooling mechanism may also be a refrigerator, an air conditioner, etc. Refrigerators and air conditioners have powerful cooling capabilities and can quickly and accurately reduce the temperature of the heating clamping mechanism 1, and promptly reduce the temperature of the clamping component 11 and the hot melt glue gun. No specific limitation is made here.

[0057] like Figures 1-2 As shown, the cleaning device also includes a power supply, a second relay, a cooling start button 31, and a cooling stop button 32. The power supply can output current. The second relay is electrically connected to the cooling mechanism. The power supply, cooling start button 31, and cooling stop button 32 are all electrically connected to the second relay. The cooling start button 31 connects the second relay and the power supply to start the cooling mechanism. The cooling stop button 32 disconnects the second relay and the power supply to stop the cooling mechanism. Pressing the cooling start button 31 quickly connects the second relay and the power supply, promptly starting the cooling mechanism and rapidly reducing the temperature of the heating clamping mechanism 1. Pressing the cooling stop button 32 promptly disconnects the second relay and the power supply, stopping the cooling mechanism and avoiding energy waste. The start and stop of the cooling mechanism can be flexibly controlled according to actual needs, improving work efficiency and extending the service life of the cleaning device.

[0058] Specifically, in this embodiment, the cooling mechanism, power supply, second relay, cooling start button 31, and cooling stop button 32 form an electrical circuit connected in series. When the cooling start button 31 is pressed, the series circuit closes, and the current output from the power supply is transmitted sequentially through the second relay to the cooling mechanism. The cooling mechanism starts after receiving power, thereby cooling the heating clamping mechanism 1. When the cooling stop button 32 is pressed, the series circuit immediately disconnects, cutting off the current transmission path from the power supply to the cooling mechanism. The cooling mechanism shuts down due to the loss of power supply, stopping the cooling operation on the heating clamping mechanism 1.

[0059] In this embodiment, the cleaning device also includes an electrical cabinet 100. The power supply, the first relay, the second relay, and the temperature controller are all located inside the electrical cabinet 100. The electrical cabinet 100 can protect the internal components, reduce the risk of components being corroded by dust and moisture, extend their service life, and reduce safety hazards caused by exposed components.

[0060] In this embodiment, the heating start button 21, heating stop button 22, cooling start button 31, and cooling stop button 32 are all located on the outer shell of the electrical cabinet 100. The heating and cooling functions can be easily controlled without opening the electrical cabinet 100, thereby improving operational efficiency and ensuring the orderly conduct of cleaning operations.

[0061] In this embodiment, both the first clamping member 111 and the second clamping member 112 are made of metal. Metal clamping members have good thermal conductivity, enabling them to quickly transfer heat from the heating component 12 to the hot melt glue gun, thus improving cleaning efficiency.

[0062] Specifically, both the first clamping member 111 and the second clamping member 112 are made of aluminum, which heats up quickly, greatly shortening the heating time and improving cleaning efficiency, while also facilitating temperature measurement by the temperature sensing element. In other embodiments, the first clamping member 111 and the second clamping member 112 can also be made of copper, stainless steel, ceramic, etc., without specific limitations, as long as they can stably clamp the hot melt glue gun while having good thermal conductivity.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
