Description

TECHNICAL FIELD

[0001] The present application relates to mirror roller technical field, specifically to a kind of heating mirror roller structure. BACKGROUND

[0002] Mirror roller is mainly used to carry out calendering treatment to the surface of object, and can be applied to calendering processing of pure cotton, polyester cotton, silk fabric, chemical fiber, hemp, wool and its blended fabric in printing and dyeing industry, calendering processing of artificial leather in leather industry, calendering processing of various plastics such as PVC, ABA, PP, PT and PC in plastic industry, surface calendering processing of various paper in papermaking industry, and calendering processing of various non-ferrous metals in metallurgical industry. The mirror roller on the market is directly heated by electric heating tube, and the electric heating tube is installed in the roller. The heat generated by the electric heating tube is transmitted by heat radiation and air convection. The main disadvantage of this structure of mirror roller is that it is difficult to adjust the temperature due to uneven heating. The temperature is high in some places and low in some places on the outer surface of the roller. The temperature of the roller body cannot be accurately detected by a single temperature sensor, so the temperature of the roller body cannot be adjusted. SUMMARY

[0003] (I) Technical problem solved

[0004] In view of the deficiencies of the prior art, the present application provides a kind of heating mirror roller structure, with the advantages of being able to adjust the temperature of the roller body and having high accuracy of the adjusting device, solving the problem that a single temperature sensor cannot accurately detect the temperature of the roller body surface, so the temperature of the roller body cannot be adjusted.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose of adjusting the temperature of the roller body and having high accuracy of the adjusting device, the present application provides the following technical solution: a kind of heating mirror roller structure, comprising a mirror roller, the mirror roller is symmetrically provided with a connecting column with a groove at the end on both sides, and a bearing is arranged in the groove, the outer end of the connecting column is provided with an inner cavity tube, and a heating wire is arranged between the mirror roller and the inner cavity tube, the inner wall of the bearing is provided with a mounting column, and the side end of the mounting column is respectively provided with an expansion pipe and an auxiliary pipe, the inside of the expansion pipe and the inside of the auxiliary pipe are respectively provided with a liquid cavity and a cavity, and a movable block is arranged at the pipe wall connection, the bottom end of the pipe wall of the expansion pipe and the bottom end of the pipe wall of the auxiliary pipe are provided with a trigger button, and the outer end of the trigger button in the expansion pipe is provided with a sealing ring, the outer end of the auxiliary pipe is provided with a heat insulation sleeve, the outer end of the expansion pipe is provided with a heat conduction plate at equal intervals, and the bottom end of the expansion pipe and the bottom end of the auxiliary pipe are provided with a same counterweight.

[0007] Preferably, the connecting column is fixedly installed on both sides of the mirror roller, and the bearing is fixedly installed in the groove at the end.

[0008] Through the technical scheme, the connecting column is fixedly installed on both sides of the mirror roller, so that the installation is more convenient, and the mirror roller can be driven to rotate when the connecting column rotates on the work roller frame. Since the connecting column is provided with a bearing at the end, the mounting column of the inner wall of the bearing does not rotate when the connecting column rotates.

[0009] Preferably, the inner cavity pipe is fixedly installed at the outer end of the connecting column, and a heating wire is fixedly installed at the outer end of the inner cavity pipe.

[0010] Through the technical scheme, the outer end of the inner cavity pipe is attached to the outer end of the heating wire, so that the heating wire uniformly conducts the temperature to the inside of the inner cavity pipe, and the other end of the heating wire is attached to the inner wall of the mirror roller, so that the temperature of the mirror roller is the same as that of the inner cavity pipe, thereby facilitating subsequent adjustment.

[0011] Preferably, the expansion pipe is fixedly installed at the side end of the mounting column, and is provided with a liquid cavity inside, and the auxiliary pipe is fixedly installed at the side end of the mounting column, and is provided with a cavity inside.

[0012] Through the technical scheme, the liquid in the liquid cavity inside the expansion pipe does not completely fill the liquid cavity. After the expansion pipe is heated, the internal liquid expands to push the movable block until the movable block touches the trigger button to stop the heating of the heating wire.

[0013] Preferably, the expansion pipe end and the auxiliary pipe end are fixedly connected, and have excellent sealing performance. The expansion pipe inner wall bottom end and the auxiliary pipe inner wall bottom end are both fixedly installed with a trigger button. The trigger button is in circuit connection with the heating wire. The expansion pipe inside the trigger button outer end is fixedly installed with a sealing ring, and the trigger button has waterproof performance.

[0014] Through the technical scheme, when the mirror roller works, the roller surface temperature needs to be kept in the most suitable temperature range. If the temperature is too high, the workpiece is easily damaged. If the temperature is too low, the processing is insufficient. The heating wire continuously heats, and the temperature continuously rises, so that the liquid inside the expansion pipe expands. Since the auxiliary pipe outer end is provided with a heat insulation sleeve, the temperature inside the auxiliary pipe rises relatively slowly, so that a pressure difference is generated inside the pipeline. The movable block is gradually pushed by the expanded liquid until it is pressed to the trigger button. At this time, the heating wire is de-energized to stop heating. With the de-energization of the heating wire, the liquid inside the expansion pipe gradually shrinks. Since the temperature inside the auxiliary pipe decreases slowly, the pressure inside the auxiliary pipe is greater than that inside the expansion pipe, so as to push back the movable block. When the temperature decreases to a threshold value, the trigger button inside the expansion pipe is triggered, so that the heating wire is energized to heat, so that the temperature of the mirror roller rises. The temperature of the roller body is adjusted to ensure that the mirror roller is always at the best working temperature.

[0015] The expansion pipe is internally provided with a liquid cavity, and the auxiliary pipe is internally provided with a cavity.

[0016] By the above technical scheme, the movable block is kept at the pipe connection position during work, and the optimal temperature range required during processing different objects is different, at this time, the work requirement can be adjusted by adjusting the volume of the heat-sensitive liquid in the expansion pipe, thereby facilitating the workers.

[0017] Preferably, the movable block is movably connected to the inner wall of the expansion pipe and the inner wall of the auxiliary pipe and closely adheres to the inner wall thereof, the movable block itself has poor heat conductivity, and the part in contact with the pipe is made of rubber.

[0018] By the above technical scheme, the sealing property of the movable block needs to be guaranteed when the movable block moves between the pipes, so as to ensure that the internal gas or heat-sensitive liquid does not flow out during work, thereby affecting the triggering of the trigger button.

[0019] Preferably, the outer end of the auxiliary pipe is sleeved with a heat insulation sleeve, the outer end of the expansion pipe is fixedly installed with a plurality of groups of heat conducting plates at equal intervals, the heat conducting plates are closely adhered to the inner wall of the inner cavity pipe, the heat conducting plates are made of a material with excellent heat conductivity, and the counterweight is fixedly installed at the bottom end of the expansion pipe and the bottom end of the auxiliary pipe, and the weight of the counterweight is greater than the sum of the weights of the expansion pipe, the auxiliary pipe, the liquid in the liquid cavity and the heat conducting plates.

[0020] By the above technical scheme, the heat insulation sleeve at the outer end of the auxiliary pipe can effectively prevent the internal temperature of the auxiliary pipe from changing greatly, so that the heat change in the expansion pipe is more intense, thereby making the pressure difference more obvious, and the heat conducting plates closely adhere to the inner cavity pipe, so that the heat on the inner cavity pipe is transferred more quickly without air resistance, and since the mirror roller is always rotating during work, the counterweight cooperates with the bearing at the end of the connecting column to ensure that the expansion pipe and the auxiliary pipe do not rotate, thereby ensuring that the external rotation has little effect on the heat-sensitive liquid, thereby reducing the error.

[0021] Compared with the prior art, the present application provides a heating mirror roller structure, which has the following beneficial effects:

[0022] 1. When the mirror roller is working, the roller surface temperature must be kept within the optimal temperature range. If the temperature is too high, it may damage the workpiece; if the temperature is too low, the processing will be insufficient. The heating wire continues to heat, and the temperature continues to rise, causing the liquid inside the expansion tube to expand. Because the auxiliary tube is equipped with a heat insulation sleeve at the outer end, the temperature inside the auxiliary tube rises more slowly, resulting in a pressure difference inside the tube. The movable block is gradually pushed by the expanding liquid until the trigger button is pressed. At this time, the heating wire is de-energized and stops heating. As the heating wire is de-energized, the liquid inside the expansion tube gradually shrinks back. At the same time, because the temperature inside the auxiliary tube drops more slowly, the pressure inside the auxiliary tube is greater than that inside the expansion tube, thus pushing the movable block back. When the temperature drops to the threshold, the trigger button inside the expansion tube is triggered, which energizes the heating wire and heats it up, thereby raising the temperature of the mirror roller. This achieves the regulation of the roller body temperature, ensuring that the mirror roller is always at the optimal working temperature.

[0023] 2. The heat insulation sleeve at the outer end of the auxiliary tube can effectively isolate the large temperature changes inside the auxiliary tube, making the heat changes inside the expansion tube more drastic, thus making the pressure difference more obvious. At the same time, the heat-conducting plate is in close contact with the inner tube, so that the heat on the inner tube is transferred without air resistance, making it faster.

[0024] 3. Since the mirror roller is always rotating during operation, the added counterweight and the bearing at the end of the connecting column ensure that the expansion tube and auxiliary tube never rotate, thus preventing the influence of external rotation on the heat-sensitive liquid and reducing the occurrence of errors.

[0036] Specific, the liquid cavity 9 in expansion pipe 7 is injected with heat-sensitive liquid, and the pressure in the cavity 10 in auxiliary pipe 8 is kept at the position of movable block 16 at the pipe connection when the heating is best, and the advantage is that when working, the movable block 16 should be kept at the pipe connection, and when processing different objects, the most suitable temperature range required is also different, at this time, the volume of heat-sensitive liquid in expansion pipe 7 can be adjusted to adjust the working requirement, so as to facilitate the staff.

[0037] Specific, the movable block 16 is movably connected to the inner walls of expansion pipe 7 and auxiliary pipe 8, and closely adheres to the inner walls, the movable block 16 itself has poor thermal conductivity, and the part in contact with the pipeline is made of rubber material, and the advantage is that when the movable block 16 moves between the pipelines, the sealing property needs to be guaranteed to ensure that the internal gas or heat-sensitive liquid does not flow out during work, so as to affect the triggering of trigger button 11.

[0038] Specifically, the auxiliary pipe 8 is sleeved with a heat insulation sleeve 12 at the outer end, a plurality of groups of heat conducting plates 13 are fixedly installed at the outer end of the expansion pipe 7 at equal intervals, and the heat conducting plates 13 are attached to the inner wall of the inner cavity pipe 3, the heat conducting plates 13 are made of excellent heat conducting material, the counterweight 15 is fixedly installed at the bottom end of the expansion pipe 7 and the bottom end of the auxiliary pipe 8, and the weight of the counterweight 15 should be greater than the sum of the weights of the expansion pipe 7, the auxiliary pipe 8, the liquid in the liquid cavity 9 and the heat conducting plates 13, and the heat insulation sleeve 12 at the outer end of the auxiliary pipe 8 can effectively prevent the temperature inside the auxiliary pipe 8 from changing greatly, so that the heat inside the expansion pipe 7 changes more dramatically, thereby making the pressure difference more obvious, and the heat conducting plates 13 are attached to the inner cavity pipe 3, so that the heat on the inner cavity pipe 3 is transferred more quickly and avoids air heat resistance.

The heating wire 2 continuously heats, the temperature continuously rises, so that the liquid inside the expansion pipe 7 expands. Since the auxiliary pipe 8 is provided with a heat insulation sleeve 12 at the outer end, the temperature inside the auxiliary pipe 8 rises relatively slowly, thereby generating a pressure difference inside the pipe. The movable block 16 is gradually pushed by the expanded liquid until it is pressed to the trigger button 11. At this time, the heating wire 2 is de-energized to stop heating. With the de-energization of the heating wire 2, the liquid in the expansion pipe 7 gradually shrinks, and because the temperature inside the auxiliary pipe 8 decreases slowly, the pressure inside the auxiliary pipe 8 is greater than that inside the expansion pipe 7, thereby pushing the movable block 16 back. When the temperature drops to the threshold value, the trigger button 11 inside the expansion pipe 7 is triggered, so that the heating wire 2 is energized to heat, thereby raising the temperature of the mirror roller 1, so as to adjust the temperature of the roller body and ensure that the mirror roller 1 is always at the optimum working temperature.
