[0029] In order to make the technical solution and advantages of the utility model clearer, the utility model and its beneficial effects will be further described in detail below in combination with specific implementation methods and drawings of the specification, but the implementation methods of the utility model are not limited thereto.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0032] like Figures 1 to 4As shown, a hot melt adhesive storage barrel comprises a storage barrel 1, a cover plate 2, a connector 3, a heating box 5 and a bracket 6, wherein the storage barrel 1 has a cavity 11 for storing hot melt adhesive, and a discharge port 12 is provided on one side of the storage barrel 1; the cover plate 2 is detachably arranged on the top of the storage barrel 1, and is used to open and close the container; the connector 3 is arranged on the bottom of the storage barrel 1, and a heating pipe 4 is provided at one end of the connection, and the heating pipe 4 is located in the cavity 11; the heating box 5 is sleeved on the outside of the storage barrel 1, and a heating cavity 51 is formed between the inner side of the heating box 5 and the storage barrel 1, and a heating rod 9 is provided in the heating cavity 51, and a water inlet 52 is provided on one side of the heating box 5; the bracket 6 is arranged at the bottom of the heating cavity 51, and is in contact with the bottom of the storage barrel 1 for support, and a connecting pipe 7 is provided on the bracket 6, and the connecting pipe 7 is connected to the other end of the connector 3, so that the heating pipe 4 is connected to the heating cavity 51.

[0033] Specifically, when the hot melt adhesive needs to be transported, the hot melt adhesive is first stored in the cavity 11 of the storage barrel 1, and the cover plate 2 is connected to the storage barrel 1 to close the cavity 11 filled with the hot melt adhesive. Then, water is injected into the heating cavity 51 through the water inlet 52. Since the heating pipe 4 is connected to the heating cavity 51, the water fills the heating cavity 51 and the heating pipe 4. Then, the heating rod 9 is turned on. When the heating rod 9 operates to heat the water to a preset temperature, the heating rod 9 stops heating. At this time, the water reaching the preset temperature conducts heat through the storage barrel 1, and the temperature in the cavity 11 can be heated and processed to ensure the effectiveness of the hot melt adhesive. At the same time, the heating cavity 51 surrounds the outer wall of the storage barrel 1, which increases the range of heating the hot melt adhesive and improves the uniformity of heating the hot melt adhesive in the cavity 11. The setting of the heating pipe 4 in the cavity 11, the heating pipe 4 is located in the cavity 11 of the hot melt adhesive storage barrel, and it is connected to the heating cavity 51 in the heating box 5 through the connector 3 and the connecting pipe 7. This design allows the heating pipe 4 to directly heat the hot melt adhesive in the cavity 11, rather than relying solely on the indirect heating of the storage barrel 1 by the external heating box 5. Through the cooperation of the heating pipe 4 and the heating cavity 51, the inside and outside of the hot melt adhesive in the cavity 11 are heated simultaneously, thereby ensuring uniform heating of the hot melt adhesive in the cavity 11.

[0034] The heating pipe 4 is a straight pipe. Specifically, the heating pipe 4 is set to a straight pipe shape, which can quickly and evenly transfer heat, and the straight pipe shape design is relatively simple, which reduces the loss of heat during the transfer process and improves thermal efficiency. Therefore, the hot melt adhesive can quickly reach a molten state, thereby improving production efficiency.

[0035] Two heating rods 9 are provided, and the two heating rods 9 are arranged on opposite sides of the heating chamber 51. Specifically, the design that the two heating rods 9 are respectively located on opposite sides of the heating chamber 51 enables the two heating rods 9 to work simultaneously to heat the water on both sides of the heating chamber 51, which can quickly increase the temperature in the heating chamber 51, thereby accelerating the melting speed of the hot melt adhesive. This helps to improve production efficiency and reduce waiting time.

[0036] In other embodiments, the number of the heating rods 9 may be 3, 4 or 5.

[0037] It should be noted that the heating rod 9 is usually connected to a temperature control system, and the power and temperature of the heating rod 9 can be adjusted as needed. By accurately controlling the temperature of the heating rod 9, the hot melt adhesive can be melted within a suitable temperature range to avoid material decomposition or burning caused by overheating.

[0038] In some embodiments of the present application, the heating pipe 4 is spiral. Specifically, the design of the spiral heating pipe 4 increases the length of the pipe, thereby increasing the contact surface 811 with the hot melt adhesive. When the heating pipe 4 is powered on to generate heat, the spiral pipe structure can more effectively transfer heat to the hot melt adhesive, thereby shortening the heating time and improving the heating efficiency.

[0039] In some embodiments of the present application, a stirring assembly 8 is further included. The stirring assembly 8 is disposed on the cover plate 2. The stirring assembly 8 includes a stirring rod 81. The stirring rod 81 is rotatably disposed on the cover plate 2. The stirring assembly 8 drives the stirring rod 81 to rotate and stir the hot melt adhesive in the cavity 11. Specifically, the stirring assembly 8 drives the stirring rod 81 to rotate in the cavity 11, thereby achieving uniform stirring and accelerated melting of the hot melt adhesive, improving production efficiency, preventing overheating and deterioration, and enhancing the adhesion of the glue.

[0040] The rotation of the stirring rod 81 can make the hot melt adhesive flow and mix evenly in the cavity 11, avoiding the precipitation and stratification of the hot melt adhesive and ensuring the uniformity of the hot melt adhesive. The stirring process can accelerate the melting of the hot melt adhesive and make it reach the desired melting state more quickly. This helps to improve production efficiency and reduce waiting time. In addition, the stirring action of the stirring rod 81 can keep the hot melt adhesive in a flowing state and prevent it from burning or deteriorating due to local overheating.

[0041] In addition, during the stirring process, the small rubber balls will collide with each other. As the temperature rises and the stirring force increases, large rubber balls will form between the small rubber balls, thereby enhancing the adhesion of the glue. This is particularly important in the preparation and processing of hot melt adhesives.

[0042] In some embodiments of the present application, the heating pipe 4 is located in the middle of the cavity 11, and the stirring rod 81 is in an inverted U shape, and is in a semi-enclosed state with the heating pipe 4. Specifically, the heating pipe 4 is located in the middle of the cavity 11, so that the hot melt adhesive can be heated more evenly when heated. Since the heating pipe 4 is directly located in the center of the hot melt adhesive, the heat can be transferred to each part of the hot melt adhesive more quickly, thereby avoiding the quality problems of the hot melt adhesive caused by local overheating or uneven heating. The inverted U-shaped design of the stirring rod 81 forms a semi-enclosed state with the heating pipe 4, so that the stirring rod 81 can contact the hot melt adhesive more comprehensively when rotating, and stir and flip the hot melt adhesive between the heating pipe 4 and the inner wall of the cavity 11; this design not only enhances the stirring effect, keeps the hot melt adhesive fluid during the heating process, prevents the precipitation and solidification of the hot melt adhesive, but also improves the heating efficiency of the hot melt adhesive. Due to the optimized design of the heating pipe 4 and the stirring rod 81, the hot melt adhesive can reach the required temperature and state more quickly during the heating and stirring process.

[0043] In addition, the heat transfer is mainly through heat conduction and convection. The spiral pipe not only increases the contact surface 811 of heat conduction, but also, due to the special shape of the spiral pipe, can produce a certain degree of convection effect with the rotating stirring rod 81, so that the hot melt adhesive is heated more evenly during the heating process.

[0044] In some embodiments of the present application, the stirring rod 81 has at least one contact surface 811 in a vertical state, and the contact surface 811 abuts against the inner wall of the cavity 11. Specifically, when the stirring rod 81 has a contact surface 811 in a vertical state, and abuts against the inner wall of the cavity 11 through the contact surface 811, when the stirring rod 81 rotates, its vertical contact surface 811 will contact and rub against the inner wall of the cavity 11. This design ensures that the stirring rod 81 can scrape and stir to a certain extent along the inner wall of the cavity 11 when rotating, effectively preventing the hot melt adhesive from being deposited and attached to the inner wall of the cavity 11. The maintenance cost and time generated by cleaning the deposits are reduced.

[0045] In some embodiments of the present application, the stirring assembly 8 further includes a motor 83, a bearing seat 82 and a protective cover 84, the bearing seat 82 is arranged on the cover plate 2, the stirring rod 81 is installed on the bearing seat 82, the motor 83 is connected to the stirring rod 81, and the protective cover 84 is arranged on the top of the cover plate 2 to shield the motor 83 and part of the stirring rod 81. Specifically, the motor 83 is the power source of the stirring assembly 8, and the motor 83 is connected to the stirring rod 81. When the motor 83 is started, the rotational power is transmitted to the stirring rod 81, so that the stirring rod 81 rotates in the cavity 11. The stable rotational motion of the stirring rod 81 helps to mix the hot melt adhesive more evenly, avoiding local overheating or uneven mixing. The protective cover 84 is arranged on the top of the cover plate 2, and its main function is to shield the motor 83 and part of the stirring rod 81; it not only protects the motor 83 and the stirring rod 81 from interference and damage from the external environment, but also ensures the safety of the operator and prevents accidental injuries that may be caused by the rotation of the stirring rod 81. The use of the bearing seat 82 reduces the friction and resistance of the stirring rod 81 during the rotation process, reduces the wear degree of the equipment and the noise when the stirring rod 81 rotates.

[0046] In some embodiments of the present application, the cover plate 2 is threadedly connected to the storage barrel 1, and a handle 21 is provided on the top of the storage barrel 1. Specifically, the cover plate 2 and the top of the storage barrel 1 are tightly combined through the threaded connection to ensure the sealing and stability of the storage barrel 1. The handle 21 provided on the top of the storage barrel 1 is for the convenience of users to operate, such as lifting, moving or rotating the storage barrel 1.

[0047] In other embodiments, the connector 3 may be connected to the heating pipe 4 and the connecting pipe 7 by threaded connection. In other embodiments, the connector 3 may be configured as a two-way pipe.

[0048] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
