Description

Technical Field

[0001] This utility model belongs to the field of printing adhesive technology, specifically relating to an adhesive supply device for automatic adhesive equipment. Background Technology

[0002] An adhesive supply unit is a key component in automated adhesive bonding equipment. It primarily stores, transports, and controls the supply of adhesive to ensure stable and accurate application of adhesive to target locations during production. It is widely used in various industrial sectors, including electronics, automotive, medical, and packaging, and plays a particularly crucial role in the printing industry. For example, in label printing and hardcover bookbinding, the adhesive supply unit precisely applies adhesive to paper or covers, ensuring bonding quality and production efficiency.

[0003] Existing glue dispensing devices deliver glue from a storage tank to a guide head. After dispensing, excess glue may drip from the guide head. This excess glue not only causes waste but can also accumulate inside the equipment or in the working environment, affecting cleanliness and operational efficiency. Furthermore, the problem is exacerbated when the dispensing device handles glue with a pungent odor. During dispensing, the pungent odor is released along with the glue, directly impacting the quality of the working environment. This odor may pose a potential health hazard to operators, reduce workplace comfort, and negatively affect work efficiency and employee morale. Utility Model Content

[0004] The purpose of this invention is to provide a glue supply device for automatic adhesive equipment, so as to solve the problems mentioned in the background art, such as waste and pollution caused by excess glue dripping from the glue guide head, and the impact of odor on the working environment and personnel health when handling irritating odor glue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue supply device for an automatic adhesive equipment, comprising: a base, a glue storage cylinder disposed above the base, a support column installed between the glue storage cylinder and the base, a pump body installed at the discharge end of the glue storage cylinder, a guide hose connected to the discharge end of the pump body, a guide head installed at the end of the guide hose away from the pump body, an mounting plate disposed above the base, a support assembly disposed between the mounting plate and the base, a telescopic assembly disposed between the mounting plate and the guide head, an mounting groove formed in the mounting plate, a heating wire installed on the inner wall of the mounting groove, a storage funnel installed on the inner wall of the mounting plate, and a cover installed at the bottom of the storage funnel.

[0006] Preferably, the telescopic assembly includes a fixed plate, an electric push rod, and a connecting plate. The fixed plate is connected to the outer wall of the mounting plate, the connecting plate is fixed to the outer wall of the guide head, and the electric push rod is installed between the fixed plate and the connecting plate.

[0007] Through the above technical solution:

[0008] In use, the base serves as the core support structure of the entire glue supply device, providing a stable installation platform for the entire system and ensuring the stability of all components during operation. The glue storage cylinder is located above the base and stores the glue to be delivered; its design ensures stable storage and smooth supply of the glue.

[0009] During the glue supply process, the pump starts and delivers the glue from the storage tank to the guide head at a constant flow rate and pressure through the guide hose. The guide hose is made of a corrosion-resistant and high-temperature-resistant flexible material to ensure that the glue is not contaminated or deteriorated during transportation.

[0010] Just before the adhesive guide head is about to discharge the adhesive, the electric push rod starts working. Driven by a motor, the electric push rod retracts, which in turn drives the discharge end of the adhesive guide head along a preset trajectory through the mounting groove, completing the adhesive supply operation outside the mounting plate.

[0011] After the adhesive is discharged, the electric push rod is activated again to extend, causing the discharge end of the guide head to retract into the mounting groove. This design not only protects the guide head from external interference but also ensures the overall neatness and safety of the device.

[0012] The inner wall of the mounting slot is equipped with a storage funnel, positioned directly below the discharge end of the retracted guide head. Due to gravity, the storage funnel effectively catches any excess adhesive that may drip from the guide head during retraction. This design not only prevents adhesive waste but also facilitates subsequent recycling and processing.

[0013] In addition, the heating wire installed on the inner wall of the mounting slot can continuously heat the adhesive material located in the guide head. This function effectively prevents the adhesive material from solidifying or clogging at low temperatures, ensuring the fluidity and stability of the adhesive material during the dispensing process, thereby guaranteeing the efficiency and reliability of the entire adhesive supply process.

[0014] The side wall of the mounting plate is equipped with an air extraction pipe. The outlet end of the air extraction pipe is connected to a first air guide pipe. The outlet end of the first air guide pipe is equipped with a purification box. The outlet end of the purification box is equipped with an air extraction assembly.

[0015] Preferably, the air extraction assembly includes a second air guide pipe and an air extractor, wherein the second air guide pipe is connected to the air outlet of the purification box, and the air extractor is installed at the air outlet of the second air guide pipe.

[0016] Through the above technical solution:

[0017] When handling adhesives with pungent odors, the vacuum pump is activated. The vacuum pump generates continuous suction through the second air duct, creating a negative pressure environment inside the purification chamber. This negative pressure is then transmitted to the extraction duct via the first air duct, giving it powerful suction.

[0018] The suction force of the extraction pipe acts around the discharge end of the glue guide head, drawing in the gas containing an irritating odor generated during the glue supply process. This gas is then guided into the purification chamber through the extraction pipe and the first air guide pipe.

[0019] The purification chamber is equipped with adsorbent materials, such as activated carbon, which have a strong adsorption capacity for pungent odors. When gases containing pungent odors enter the purification chamber, the adsorbents, such as activated carbon, can quickly capture and fix these odor molecules, effectively removing odor components from the air. This process ensures that the gas discharged from the purification chamber is clean and harmless, thereby guaranteeing a good working environment and protecting the health of operators.

[0020] The support assembly includes a bearing plate, a hollow plate, and a support plate. The bearing plate is fixed to the bottom end of the mounting plate, the hollow plate is installed on the upper surface of the base, and the support plate is installed at the bottom end of the bearing plate, with a portion of the support plate extending into the hollow plate. A limit component is provided between the hollow plate and the support plate.

[0021] Preferably, the limiting component includes a slot, multiple through slots, and a pin. The slot is formed on the side wall of the hollow plate, the multiple through slots are evenly distributed at equal intervals on the side wall of the support plate, and the pin is inserted horizontally between the slot and the through slots.

[0022] Through the above technical solution:

[0023] In use, the adhesive supply device's support system, through the coordinated action of the carrier plate, hollow plate, and support plate, allows for easy adjustment by the operator when the height of the mounting plate needs to be adjusted to accommodate different adhesive supply requirements. First, pull out the pin to release its fixation on the support plate. This step allows the support plate to move freely between the slot and the through slot. Next, pull out the support plate and move it to the appropriate position as needed. Align the slot and through slot, ensuring the pin can be easily inserted. This step ensures the support plate is locked in the new position.

[0024] This simple adjustment mechanism allows the mounting plate to change its height, and the adhesive guide head, as the connecting part of the mounting plate, moves accordingly. This design enables the adhesive guide head to adapt to various adhesive supply needs, easily handling both supply points at different heights and complex workpieces requiring alignment.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) This utility model achieves protection of the guide head and recycling of excess adhesive by setting up components such as a guide head, an electric push rod, and a storage funnel. Before discharging the adhesive, the electric push rod retracts, driving the guide head to extend through the mounting groove to the outside for adhesive supply; after the adhesive supply is completed, the electric push rod extends and retracts the guide head back into the mounting groove, which not only protects the guide head but also keeps the device clean; when the guide head is retracted, the storage funnel can catch any excess adhesive that may drip, effectively avoiding adhesive waste and facilitating recycling.

[0027] (2) This utility model achieves effective absorption of irritating odors by setting up components such as an exhaust pipe, a purification chamber, and an exhaust fan. In use, the exhaust fan is turned on to create a negative pressure environment inside the purification chamber. The exhaust pipe then draws the gas containing the irritating odor from around the guide head into the purification chamber. The activated carbon and other adsorption materials filled inside the purification chamber efficiently capture odor molecules, removing odors from the inhaled gas and ensuring that the discharged gas is clean and harmless, thereby effectively protecting the health of the operators.

[0034] 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.

[0035] Please see Figures 1-3 As shown, this utility model provides the following technical solution: a glue supply device for an automatic adhesive equipment, comprising: a base 1, a glue storage cylinder 2 disposed above the base 1, a support column 3 installed between the glue storage cylinder 2 and the base 1, a pump body 4 installed at the discharge end of the glue storage cylinder 2, a guide hose 5 connected to the discharge end of the pump body 4, a guide head 6 installed at the end of the guide hose 5 away from the pump body 4, an mounting plate 7 disposed above the base 1, a support assembly disposed between the mounting plate 7 and the base 1, a telescopic assembly disposed between the mounting plate 7 and the guide head 6, an mounting groove 8 opened in the mounting plate 7, an electric heating wire 14 installed on the inner wall of the mounting groove 8, a storage funnel 9 installed on the inner wall of the mounting plate 7, and a cover 10 installed at the bottom end of the storage funnel 9.

[0036] Furthermore, the telescopic assembly includes a fixed plate 11, an electric push rod 12, and a connecting plate 13. The fixed plate 11 is connected to the outer wall of the mounting plate 7, the connecting plate 13 is fixed to the outer wall of the guide head 6, and the electric push rod 12 is installed between the fixed plate 11 and the connecting plate 13.

[0037] Through the above technical solution:

[0038] In use, the base 1 serves as the core support structure of the entire glue supply device, providing a stable installation platform for the entire system and ensuring the stability of all components during operation. The glue storage cylinder 2 is located above the base 1 and stores the glue to be delivered. Its design ensures stable storage and smooth supply of the glue.

[0039] During the glue supply process, the pump body 4 starts, and the glue in the glue storage tank 2 is delivered to the glue guide head 6 at a constant flow rate and pressure through the material guide hose 5. The material guide hose 5 is made of a corrosion-resistant and high-temperature resistant flexible material to ensure that the glue is not contaminated or deteriorated during the transportation process.

[0040] Just before the adhesive guide head 6 is about to discharge the adhesive, the electric push rod 12 starts to work. The electric push rod 12 is driven by a motor to achieve a retracting motion, thereby driving the discharge end of the adhesive guide head 6 to pass through the mounting groove 8 along a preset trajectory, completing the adhesive supply operation outside the mounting plate 7.

[0041] After the adhesive is discharged, the electric push rod 12 is activated again to extend, causing the discharge end of the guide head 6 to retract into the mounting groove 8. This design not only protects the guide head 6 from external interference but also ensures the overall neatness and safety of the device.

[0042] The inner wall of the mounting groove 8 is fitted with a storage funnel 9, which is positioned directly below the discharge end of the retracted guide head 6. Due to gravity, the storage funnel 9 effectively catches any excess adhesive that may drip from the guide head 6 during retraction. This design not only avoids adhesive waste but also facilitates subsequent recycling and processing.

[0043] In addition, the heating wire 14 is installed on the inner wall of the mounting groove 8, which can continuously heat the adhesive material located in the guide head 6. This function effectively prevents the adhesive material from solidifying or clogging at low temperatures, ensuring the fluidity and stability of the adhesive material during the dispensing process, thereby guaranteeing the efficiency and reliability of the entire adhesive supply process.

[0044] Please see Figures 1-4 As shown, an exhaust pipe 15 is installed on the side wall of the mounting plate 7. The discharge end of the exhaust pipe 15 is connected to a first air guide pipe 16. A purification box 17 is installed at the discharge end of the first air guide pipe 16. An exhaust assembly is installed at the air outlet end of the purification box 17.

[0045] Furthermore, the air extraction assembly includes a second air duct 18 and an air extractor 19. The second air duct 18 is connected to the air outlet of the purification chamber 17, and the air extractor 19 is installed at the air outlet of the second air duct 18.

[0046] Through the above technical solution:

[0047] When handling adhesives with irritating odors, the vacuum pump 19 is activated. The vacuum pump 19 generates continuous suction through the second air guide pipe 18, creating a negative pressure environment inside the purification chamber 17. This negative pressure is further transmitted to the suction pipe 15 through the connection of the first air guide pipe 16, giving it strong suction.

[0048] The suction force of the extraction pipe 15 acts around the discharge end of the glue guide head 6, drawing in the gas containing an irritating odor generated during the glue supply process. This gas is then guided into the purification chamber 17 via the extraction pipe 15 and the first air guide pipe 16.

[0049] The purification chamber 17 is equipped with adsorbent materials, such as activated carbon, which have a strong adsorption capacity for pungent odors. When gas containing pungent odors enters the purification chamber 17, the adsorbents, such as activated carbon, can quickly capture and fix these odor molecules, effectively removing odor components from the air. This process ensures that the gas discharged from the purification chamber 17 is clean and harmless, thereby guaranteeing a good working environment and protecting the health of operators.

[0050] Please see Figures 1-5 As shown, the support assembly includes a bearing plate 20, a hollow plate 21, and a support plate 22. The bearing plate 20 is fixed to the bottom end of the mounting plate 7, the hollow plate 21 is installed on the upper end surface of the base 1, and the support plate 22 is installed on the bottom end of the bearing plate 20, with a portion of the support plate 22 extending into the hollow plate 21. A limit component is provided between the hollow plate 21 and the support plate 22.

[0051] Furthermore, the limiting component includes a slot 23, multiple through slots 24 and a pin 25. The slot 23 is formed on the side wall of the hollow plate 21, the multiple through slots 24 are evenly distributed at equal intervals on the side wall of the support plate 22, and the pin 25 is inserted horizontally between the slot 23 and the through slots 24.

[0052] Through the above technical solution:

[0053] In use, the support system of the glue supply device, through the coordinated action of the carrier plate 20, the hollow plate 21, and the support plate 22, allows the operator to easily adjust the height of the mounting plate 7 to accommodate different glue supply needs. First, pull out the pin 25 to release its fixing restriction on the support plate 22. This step allows the support plate 22 to move freely between the slot 23 and the through slot 24. Next, pull out the support plate 22 and move it to the appropriate position according to actual needs. Align the slot 23 and the through slot 24, ensuring that the pin 25 can be smoothly inserted. This step ensures that the support plate 22 is locked in the new position.

[0054] Through this simple adjustment mechanism, the mounting plate 7 can change its height, and the adhesive guide head 6, as the connecting part of the mounting plate 7, will also move accordingly. This design allows the adhesive guide head 6 to adapt to various adhesive supply needs, easily handling both adhesive supply points at different heights and complex workpieces that require alignment.

[0055] 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.
