Description

Technical Field

[0001] This utility model relates to the technical field of drilling devices, specifically a drilling structure for a calender roller. Background Technology

[0002] The drilling structure of the calender rolls is the core of its internal temperature control system, directly affecting the temperature uniformity, thermal deformation control, and production efficiency of the rolls.

[0003] The perforated structure of the calender roll is the core of its internal temperature control system. It regulates the roll surface temperature by circulating cooling medium (water, oil) or heating medium (steam, hot oil) to ensure that the material (such as rubber, plastic, metal foil) is heated evenly during the calendering process. This structure should maintain a constant temperature environment during use to avoid material sticking to the roll, surface defects, or uneven thickness.

[0004] Conventional roller drilling mechanisms still have the following problems: When using this device for drilling, the temperature of the drilling position needs to be controlled. Too high or too low a temperature will result in poor drilling effect. At the same time, because the roller needs to be drilled at an angle to connect the oil inlet and outlet, the angled fixation of the roller is more likely to cause insufficient drilling accuracy due to equipment vibration during drilling. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, such as the need for temperature control at the drilling position during drilling operations (excessive or insufficient temperatures will result in poor drilling performance), and the problem that the rollers need to be angled during drilling to connect the oil inlet and outlet, the angled fixing of the rollers can easily lead to insufficient drilling accuracy due to equipment vibration.

[0008] Therefore, the purpose of this utility model is to provide a drilling structure for a calender roller. By fixing a hot air box and a water storage tank to the top of the main body, hot air or coolant is blown or sprayed onto the roller during drilling, allowing the operator to control the temperature of the drilling area, thus improving the efficiency and effect of drilling. At the same time, inserting the roller to be drilled into the fixed inclined groove can fix most of the roller surface. If the protruding part is not convenient for drilling, the positioning screw can be adjusted. The positioning screw drives the movable block to move inside the fixed inclined groove, thereby raising or lowering the roller so that it can be easily drilled.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A drilling structure for a calender roller includes a main body. A water storage tank and a hot air box are fixedly connected to the top of the main body. An injection port is provided on the top of the water storage tank, and a level gauge is provided on the front of the water storage tank. A water pump is fixedly connected to the front of the water storage tank, and a plastic hose is fixedly connected to the side of the water pump. A nozzle is installed at one end of the plastic hose. An air inlet frame is fixedly connected to the back of the hot air box, and an air inlet motor is fixedly connected to the back of the air inlet frame. A fan blade is fixedly connected to the output end of the air inlet motor. An electric heating element is installed inside the hot air box, and a hot air pipe is fixedly connected to the front of the hot air box. An air outlet is provided at one end of the hot air pipe. The electric heating element, the air inlet motor, and the water pump are electrically connected to an external electrical distribution box via connecting wires.

[0012] As a preferred embodiment of the calender roller drilling structure of this utility model, the main body has a fixed inclined groove inside, and a positioning screw is threadedly connected to the outer circumference of the fixed inclined groove. The top end of the positioning screw is connected to a movable block through a rotating shaft.

[0013] As a preferred embodiment of the calender roller drilling structure of this utility model, the bottom four corners of the main body are fixedly connected with support feet, and the top of the main body is fixedly connected with an L-shaped plate. The device can be stably placed on the ground by means of the support feet.

[0014] As a preferred embodiment of the calender roller drilling structure of this utility model, the top of the main body is provided with a worktable, and a fixed plate is fixedly connected to the top of the worktable. The inside of the fixed plate is connected to a clamping screw through a thread, and the bottom end of the clamping screw is connected to a clamping plate through a rotating shaft. By adjusting the clamping screw, the clamping plate is driven to clamp and fix the roller protruding from the main body, which is convenient for the drilling equipment to drill holes in it.

[0015] In a preferred embodiment of the calender roller drilling structure of this utility model, a connecting plate is fixedly connected to the top of the L-shaped plate, a first drive motor is fixedly connected to the top of the connecting plate, and a telescopic rod is fixedly connected to the top of the connecting plate. The first drive motor can work with the telescopic rod to extend and retract, thereby allowing the drilling needle to move up and down.

[0016] As a preferred embodiment of the calender roller drilling structure of this utility model, an upper flange plate is fixedly connected to the outer circumference of the telescopic rod, and a lower flange plate is bolted to the inside of the upper flange plate. The upper flange plate and the lower flange plate connected by bolts can achieve the effect of quick assembly and disassembly.

[0017] In a preferred embodiment of the calender roller drilling structure of this utility model, a second drive motor is fixedly connected to the top of the lower flange plate. The output end of the second drive motor is connected to a rotating disk via a rotating shaft. A drilling needle is fixedly connected to the bottom of the rotating disk. The second drive motor is electrically connected to a distribution box via a connecting wire. Since the output end of the second drive motor is fitted into the rotating disk, the rotating disk and the drilling needle can be removed together when the lower flange plate is removed, which facilitates the replacement of the specifications of the drilling needle.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of calender roller drilling structure: By fixing a water tank and a hot air box to the top of the main body, and by starting the air intake motor and water pump, when it is necessary to increase the temperature of the drilling position, the air outlet at the bottom of the hot air pipe is aimed at the drilling position for heating, which can reduce the probability of burrs during drilling. When it is necessary to cool down, the water pump is started and the plastic hose is bent so that the nozzle is aimed at the drilling position. At the same time, the water pump draws coolant and sprays it out through the plastic hose and nozzle, thereby reducing the temperature of the drilling position and preventing the drilling needle from breaking due to excessive temperature. The temperature control effect is good.

[0021] This type of calender roller drilling structure: By opening a fixed inclined groove inside the main body of the device, the roller that needs to be drilled can be directly inserted into the fixed inclined groove. At the same time, by rotating the handle at the top of the positioning screw connected to the main body, the position of the positioning screw can be adjusted, which in turn drives the movable block connected to the bottom of the positioning screw via a rotating shaft. This allows the insertion depth of the roller inside the fixed inclined groove to be adjusted, making it easy to adjust the drilling position. Attached Figure Description

[0035] This utility model provides an overall structural diagram of an embodiment of a calender roller drilling structure, including:

[0036] Please see Figures 1-6 This embodiment of a calender roller drilling structure includes a main body 1. A water storage tank 18 and a hot air box 24 are welded to the top of the main body 1. An injection port 20 is opened on the top of the water storage tank 18, and a level gauge 19 is opened on the front of the water storage tank 18. A water pump 21 is fixedly connected to the front of the water storage tank 18 by bolts. A plastic hose 22 is fixedly connected to the side of the water pump 21 by bolts. A nozzle 23 is assembled and installed at one end of the plastic hose 22. An air inlet frame 25 is welded to the back of the hot air box 24. The back of component 5 is bolted to an air intake motor 26. A fan blade 27 is glued and fixed to the outer circumference of the output end of the air intake motor 26. An electric heating tube 28 is embedded inside the hot air box 24. A hot air pipe 29 is bolted to the front of the hot air box 24. An air outlet 30 is opened at one end of the hot air pipe 29. The electric heating tube 28, the air intake motor 26, and the water pump 21 are electrically connected to an external distribution box via connecting wires. The external distribution box is electrically connected to a control device via connecting wires. The control device refers to the control panel.

[0037] It is worth noting that, in order to fix and adjust the drilling position of the roller inside the main body 1, a fixing groove 17 is provided inside the main body 1. A positioning screw 15 is threadedly connected to the outer circumference of the fixing groove 17. The top of the positioning screw 15 is connected to a movable block 16 through a rotating shaft.

[0038] Next, in order to place the device stably, support feet 3 are welded to the four corners of the bottom of the main body 1, and an L-shaped plate 7 is welded to the top of the main body 1.

[0039] Meanwhile, in order to prevent insufficient drilling accuracy due to vibration during drilling, the main body 1 is provided with a worktable 2 at the top. A fixed plate 4 is welded to the top of the worktable 2. A clamping screw 5 is connected to the inside of the fixed plate 4 by a thread. The bottom end of the clamping screw 5 is connected to a clamping plate 6 by a rotating shaft.

[0040] Furthermore, to facilitate the driving of the telescopic rod 10, specifically, a connecting plate 8 is welded to the top of the L-shaped plate 7, and a first drive motor 9 is fixedly connected to the top of the connecting plate 8 by bolts. The telescopic rod 10 is also fixedly connected to the top of the connecting plate 8 by bolts, and the first drive motor 9 is electrically connected to an external distribution box via a connecting wire.

[0041] It is worth noting that, in order to allow for the disassembly and installation of the upper flange plate 11 and the lower flange plate 12, specifically, the upper flange plate 11 is bonded and fixedly connected to the outer circumference of the telescopic rod 10, and the lower flange plate 12 is bolted to the inside of the upper flange plate 11.

[0042] Finally, to facilitate the adjustment of the specifications of the drill bit 13, specifically, the bottom of the lower flange plate 12 is connected to the rotating disk 14 via a rotating shaft, and the bottom of the rotating disk 14 is welded and fixedly connected to the drill bit 13.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figure 1-6 The specific usage process of the calender roll drilling structure of this embodiment is as follows:

[0045] 1. When using this type of calender roll drilling structure, it is first necessary to confirm the required drilling specifications. After confirmation, it can be decided whether to replace the current drilling needle 13. When it is necessary to replace the drilling needle 13, the upper flange plate 11 and the lower flange plate 12 are separated by unscrewing the nut at the bottom of the lower flange plate 12. After separation, since the output end of the second drive motor 31 is fitted with the rotating disk 14 and fixed on the top of the lower flange plate 12, and the rotating disk 14 and the drilling needle 13 are integrated, the drilling needle 13 is replaced at the same time as the lower flange plate 12 is replaced. The lower flange plate 12 and the upper flange plate 11 are then connected again by the screw nut to replace the drilling needle 13 of different specifications.

[0046] 2. Before use, the water pump 21, air intake motor 26, electric heating element 28, first drive motor 9, and second drive motor 31 on this device need to be connected to the external electrical distribution box via connecting cables. This allows these motors to be driven. The distribution box is directly electrically connected to the control device, which is an independent operation panel. This panel can control the water pump 21, air intake motor 26, electric heating element 28, first drive motor 9, and second drive motor 31 on this device through the distribution box. Simultaneously, the roller requiring drilling should be inserted into the fixing groove 17 to secure it. The system can determine whether the part of the main body 1 that is protruding is suitable for drilling. If the part is not suitable for drilling, the positioning screw 15 can be rotated to move the movable plate inside the fixed groove 17, thereby reducing or increasing the content of the fixed groove 17 and changing the depth of the roller inserted into the main body 1. At the same time, the protruding part can be tightened by turning the clamping screw 5 inside the fixed plate 4, so that the clamping plate can stick to and clamp the part of the roller protruding from the main body 1, thereby fixing the entire roller. This makes it less likely for the roller to shift due to vibration during the drilling process, thus preventing insufficient drilling accuracy.

[0047] 3. During the drilling process, temperature control is required at the drilling location on the roller. At the start of drilling, the intake motor 26 is activated via the control panel. The intake motor 26 drives the fan blades 27 to rotate and draw in air. Simultaneously, the electric heating element 28 is activated. The drawn-in air passes directly through the heating element 28 and is heated through physical contact. The heated air is then sent into the hot air duct 29. The operator can then align the air outlet 30 at the bottom of the hot air duct 29 with the drilling location to ensure the hot air heats the area where drilling began, preventing slippage and misalignment that could lead to increased burrs. Once the hole is roughly formed, meaning a shallow hole has been drilled on the roller... When drilling, the air intake motor 26 can be turned off, and the water pump 21 can be turned on at the same time. Before use, the water pump 21 needs to be filled with coolant through the inlet 20. After starting the water pump 21 through the control panel, the water pump 21 will draw coolant from the water tank 18 and send it into the plastic hose 22. The plastic hose 22 can be bent and shaped so that the worker can aim the nozzle 23 of the plastic hose 22 at the drilling area and continuously spray coolant onto the drilling area, thereby cooling the drilling area and preventing the drill bit 13 from breaking due to the gradually rising temperature. After the entire drilling process is completed, the worker can use cleaning tools such as an absorbent cloth to clean and wipe the workbench 2 and the inside of the fixed inclined groove 17 to remove any residual coolant.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
