[0026] The core of the present application is to provide a rubber coating wheel protection device for a hard box packaging machine.

[0027] Please refer to Figures 1-2 .

[0028] The rubber coating wheel protection device for a hard box packaging machine provided by the present application comprises a main cover 1 and a sub-cover 2, the main cover 1 is arranged on the glue tank, the sub-cover 2 is arranged on the through hole opened on one side of the glue tank, and the connecting structure 4 is arranged between the main cover 1 and the sub-cover 2.

[0029] Specifically, the main cover 1 is designed to closely fit the shape of the top of the glue tank, usually made of corrosion-resistant, easy-to-clean materials such as stainless steel or special plastics, to ensure long-term contact with glue without chemical reaction or deformation. The secondary cover 2 is specially designed to cover the through hole on the side of the glue tank, which is usually used for adjustment or maintenance of the glue wheel. The secondary cover 2 is also made of corrosion-resistant material and is designed with precise dimensions to ensure a tight fit with the through hole, preventing dust, soot, and other impurities from entering the glue tank through the through hole, affecting the purity of the glue and the glue application effect. The connecting structure 4 is the key component connecting the main cover 1 and the secondary cover 2, which ensures that the two form a stable whole in the closed state, provides additional structural strength and stability, and avoids the loss of the secondary cover 2 when the two are dispersed.

[0030] It should be noted that the safety of the operator should also be considered when designing the entire protection device, such as smoothing the edges to avoid scratches, and possibly setting up a safety lock mechanism to prevent unauthorized personnel from operating at will. At the same time, in order to facilitate maintenance, some components of the protection device may need to be designed to be easily disassembled and reassembled to facilitate cleaning of the glue tank, replacement of damaged parts, or regular maintenance.

[0031] The above-mentioned hard box packaging machine glue wheel protection device covers the glue tank with the main cover 1 to protect the glue roller, and at the same time cooperates with the secondary cover 2 to seal the through hole on one side of the glue tank, achieving overall protection of the glue tank. The main cover 1 can effectively prevent the glue tank from being scratched by hard objects, and the secondary cover 2 can prevent external soot and other dirt from entering the glue, achieving overall protection of the glue tank.

[0032] The hard box packaging machine glue wheel protection device provided by the present application will be described in more detail below in conjunction with the drawings and specific embodiments.

[0033] In one specific embodiment, referring to Figure 1 and Figure 2 The connecting structure 4 includes a connecting chain 41, one end of the connecting chain 41 being connected to one side of the surface of the main cover 1, and the other end of the connecting chain 41 being connected to one side of the surface of the secondary cover 2.

[0034] Specifically, the connecting chain 41 in the connecting structure 4 plays a dual role of bridge and fixation between the main cover 1 and the auxiliary cover 2. The connecting chain 41 is made of high-strength, corrosion-resistant metal materials such as stainless steel or alloy steel to ensure that it will not break due to stress and will not be damaged due to environmental corrosion during long-term use. One end of the connecting chain 41 is connected to the surface side of the main cover 1, usually through welding, riveting or high-strength screws and other fixation methods to ensure stable and secure connection. The other end is also firmly connected to the surface side of the auxiliary cover 2 to ensure flexible and reliable connection between the two. This design allows the main cover 1 and the auxiliary cover 2 to be opened or closed independently when needed, and the connecting chain 41 serves as a link between them, maintaining the relative position relationship between the two and avoiding loss or damage due to improper operation.

[0035] It should be noted that the length and flexibility of the connecting chain 41 should ensure that the chain will not be damaged due to excessive stretching or twisting and will not limit the movement range of the two due to insufficient length when opening or closing the main cover 1 and / or the auxiliary cover 2.

[0036] It should be noted that the surface of the connecting chain 41 can also be smoothed to reduce the risk of scratches or discomfort to the operator during use. The ends of the chain can also be equipped with anti-unhooking or safety lock devices to further ensure the safety and reliability of the connection.

[0037] Based on any one of the above embodiments, referring to Figure 1 and Figure 2 , the main cover 1 is provided with a locking mechanism 5 for locking the positioning pin on the glue tank 9 to fix the main cover 1 on the glue tank 9.

[0038] Specifically, the locking mechanism 5 can achieve stability between the main cover 1 and the glue tank 9, ensuring that the two do not shake relative to each other when the main cover 1 is buckled on the glue tank 9, thereby further improving the protection effect of the device on the glue tank 9. The addition of the locking mechanism 5 makes the connection between the main cover 1 and the glue tank 9 more stable and secure, providing a strong guarantee for the normal operation of the entire glue wheel protection device. At the same time, the design of the mechanism also fully considers the convenience and safety of operation, making it easier and more efficient for the operator to complete the relevant operation.

[0039] Based on any one of the above embodiments, referring to Figure 1 and Figure 2 , the locking mechanism 5 includes a steel ball spring type locking piece 51 arranged on the side of the main cover 1 close to the glue tank 9, and the locking piece 51 is arranged in cooperation with the locking hole of the positioning pin.

[0040] Specifically, the steel ball elastic sheet type locking piece 51 can be provided with multiple, preferably two, respectively located on both sides of the bottom of the main cover 1, to ensure the stability of the locking mechanism 5 operation. The core component of the steel ball elastic sheet type locking piece 51 is one or several precisely machined steel balls, which are placed inside an elastic sheet. The design of the elastic sheet allows the steel balls to move elastically within a certain range while maintaining the locking pressure on the positioning pin. When the main cover 1 is placed on the glue tank 9, the locking port of the steel ball elastic sheet type locking piece 51 will automatically align with the positioning pin on the glue tank 9. During the locking process, as the main cover 1 gradually approaches the glue tank 9, the steel balls will be subjected to pressure from the elastic sheet and gradually pushed into the locking port. When the steel balls come into complete contact with the positioning pin, the elastic force of the elastic sheet will firmly press the steel balls against the positioning pin, forming a stable locking point. In this way, the main cover 1 is firmly fixed on the glue tank 9, and even if it encounters vibration or external force during machine operation, it can maintain the stability of the connection.

[0041] On the basis of any one of the above embodiments, with reference to Figure 1 and Figure 2 , the main cover 1 is provided with a first sealing assembly, which is used to seal between the main cover 1 and the glue tank 9.

[0042] Further, the first sealing assembly includes a detachable sealing pad 7 provided on the main cover 1, which is arranged between the main cover 1 and the glue tank 9.

[0043] Specifically, the setting of the first sealing assembly can effectively ensure the sealing of the internal environment of the glue wheel protection device of the hard box packaging machine, aiming to prevent the glue in the glue tank 9 from affecting the gluing effect and the normal operation of the machine due to volatilization, leakage or external pollution.

[0044] Optionally, the first sealing assembly includes a sealing gasket 7 detachably arranged on the main cover 1. The sealing gasket 7 is usually made of corrosion-resistant, wear-resistant and elastic materials such as silicone, fluororubber or special synthetic rubber, etc. The selection of these materials is aimed at ensuring that the sealing gasket 7 can maintain good sealing performance and durability even after long-term contact with glue and machine operating environment. The sealing gasket 7 is precisely placed on the contact surface between the main cover 1 and the glue tank 9. When the main cover 1 is fixed to the glue tank 9, the sealing gasket 7 will be compressed and fill the small gap between them. This compression and filling effect forms a tight sealing layer, effectively preventing the volatilization and leakage of glue, while also preventing the entry of external dust, moisture and other contaminants. The detachable design makes it very convenient to replace the sealing gasket 7 when it needs to be replaced due to wear or aging after long-term use. The operator only needs to loosen the locking mechanism 5, remove the main cover 1, and then easily remove the old sealing gasket 7 from the main cover 1 and install a new sealing gasket 7. This design not only improves the convenience of maintenance, but also helps to extend the service life of the entire protection device.

[0045] It should be noted that in order to facilitate the installation of the steel ball spring locking piece 51, the sealing gasket 7 is provided with a through groove at the installation position of the steel ball spring locking piece 51 to facilitate the installation of the steel ball spring locking piece 51.

[0046] On the basis of any one of the above embodiments, referring to Figure 1 and Figure 2 , a wet sponge pad 6 is arranged on the inner side of the main cover 1, and the wet sponge pad 6 is located between the glue roller in the glue tank 9 and the inner wall of the main cover 1.

[0047] Specifically, the wet sponge pad 6 is arranged on the inner side of the main cover 1 and in contact with the glue roller in the glue tank 9. The wet sponge pad 6 can be additionally filled with an appropriate amount of water to maintain the humidity of the main cover 1 and prevent the glue from solidifying. The place where the main cover 1 contacts the glue tank 9 is composed of a layer of sponge pad, which ensures the sealing contact between the main cover 1 and the glue tank 9.

[0048] On the basis of any one of the above embodiments, referring to Figure 1 , a second sealing assembly is arranged between the auxiliary cover 2 and the through hole 10, and the second sealing assembly is used for sealing between the auxiliary cover 2 and the through hole 10.

[0049] Further, the second sealing assembly includes a sealing ring 3 sleeved on the auxiliary cover 2, and the auxiliary cover 2 is provided with an annular mounting groove, and the sealing ring 3 is arranged in the mounting groove, and the sealing ring 3 is in interference fit with the inner wall of the through hole 10.

[0050] Specifically, the second sealing assembly is designed to ensure a good sealing effect between the sub-cover 2 and the through hole 10 on the main cover 1, thereby preventing external dirt such as soot and smoke from entering the glue, and ensuring the cleanliness of the inside of the glue tank 9. The second sealing assembly can be a sealing ring 3 fitted on the sub-cover 2. The sealing ring 3 is usually made of elastic materials such as rubber, silicone or fluororubber, which have good sealing performance and corrosion resistance, and can maintain stable sealing effect in long-term contact with glue and machine operating environment. A special annular mounting groove is provided on the sub-cover 2, and the size and shape of the mounting groove are matched with the sealing ring 3, so that the sealing ring 3 can be firmly installed in the groove. When the sub-cover 2 is installed on the through hole 10 of the main cover 1, the sealing ring 3 will be pressed onto the inner wall of the through hole 10, forming an interference fit. This fit allows the sealing ring 3 to closely fit the inner wall of the through hole 10, effectively preventing external dirt such as soot and smoke from entering the glue.

[0051] On the basis of any one of the above embodiments, with reference to Figure 2 Figure 1-2 Figure 1 The main cover 1 is fixedly provided with a pull handle 8 on the side away from the glue tank 9, and the surface of the pull handle 8 is provided with anti-slip patterns.

The pull handle 8 is fixedly provided on the side of the main cover 1 away from the glue tank 9, and the surface of the pull handle 8 is provided with anti-slip patterns, effectively increasing the stability and safety of the operator during gripping and pulling. The design of anti-slip patterns usually includes a series of raised textures or grooves, which can increase the friction between the hand and the pull handle 8, preventing accidents caused by hand slipping during operation.

[0053] Optionally, in order to further improve the comfort of the operator, the surface of the pull handle 8 can also be softened, such as wrapping a layer of soft rubber or plastic material.
