[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By utilizing the internal cavity of the heating roller, heated oil is injected, allowing the hot oil to transfer heat to the heating roller and achieve the heating effect. The sealing baffle can adjust the contact area between the internal cavity and the hot oil, thereby adjusting the contact position between the hot oil and the heating roller. This allows the heating position to be adjusted as needed, ensuring that areas not in operation are not heated. This reduces the need for a large heating area and high energy input required for heating the entire heating roller, while also minimizing energy waste due to the heating area not being used in production.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They 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 the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] like Figure 1 , Figure 2 As shown, a hot oil-type energy-saving heating roller includes a roller body 1. The roller body 1 is hollow in the middle to form a cavity. Two sealing blocks 4 are slidably arranged inside the roller body 1. An oil delivery hole is provided in the middle of the sealing block 4. One end of the oil delivery hole is connected to the cavity, and the other end is connected to the heating oil pump through an oil delivery pipe 2. Several threaded parts 3 that can be connected in series are sleeved on the outside of the oil delivery pipe 2. The threads on adjacent threaded parts 3 can be mated with each other. The edge threaded parts 3 can be detached and connected to the sealing blocks 4.

[0019] The product can be connected in series according to needs when in use, so that the sealing stop 4 can be pushed into the cavity by the hard support effect of the threaded part 3 in the axial direction after being connected, so as to achieve the effect of the volume of the cavity. When the volume of the cavity needs to be increased, the threaded part 3 only needs to be separated, and then the hot oil is pumped into the cavity through the heating oil pump, so that the sealing part is pushed by the hot oil, so that the sealing stop 4 moves towards both ends of the roller body 1, thereby increasing the volume of the heating roller cavity. By reducing and increasing the volume, the product can process cartons of different sizes as needed to adjust the heating position required, so that heat can better act on the carton during heating, less energy is wasted, and the effect of energy saving is achieved.

[0020] The support shaft for connecting with the printing machine is arranged at both ends of the roller body 1, and the opening for the oil supply pipe 2 and the threaded part 3 to pass through the middle part is arranged in the middle part of the support shaft. The oil supply pipe 2 is inserted into the inside and communicates with the oil supply hole through the sealing bearing, so that the roller body 1 does not cause the oil supply pipe 2 to be knotted during rotation. The threaded part 3 is connected with the sealing part by using a common bearing, so that the threaded part 3 does not drive the sealing part to rotate during rotation, so that the sealing part is better pushed.

[0021] The threaded part 3 is arranged at the opening of the roller body 1 and cooperates with the threaded part 3. The threaded part 3 is pushed by the axial force of the threaded part at the opening during rotation, so that the threaded part 3 is pushed in the axial direction. The moving threaded part 3 can drive the sealing part to move in the axial direction, so that the volume of the cavity changes, and the area of the hot oil contacting the roller body 1 changes, so that the heat transfer of the hot oil can better act on the required position, the energy utilization rate is improved, and the unnecessary energy loss is reduced.

[0022] The threaded part 3 is provided with a protrusion at one end and a groove at the other end, and the protrusion can be inserted into the groove. The protrusion is inserted into the groove, so that the rotation force can be better transmitted along the threaded part 3 during rotation. The protrusion is provided with three protrusions, and the included angle between adjacent protrusions is 120°, so that the threaded part 3 does not slide in other directions in the axial direction during use, so that the threaded part 3 is better kept in a fixed position.

[0023] The convex is provided with a positioning hole 5, a ball head plunger is screwed into the positioning hole 5, a positioning groove is arranged in the recess, the ball head plunger can be clamped into the positioning groove, the ball head plunger has the effect of positioning and fixing, so that when the convex is clamped into the recess, the effect of positioning and fixing can be better, and when it is needed to separate, only a pulling force greater than the inside of the ball head plunger is needed to pull out the convex from the positioning groove, the effects of convenient disassembly and stable installation are achieved, so that the threaded part 3 can be more stable when supporting the sealing plug.

[0024] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims. Any reference signs in the claims should not be considered as limiting the claims to which they relate.

[0025] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be properly combined to form other embodiments that those skilled in the art can understand.
