Description

Technical Field

[0001] This application relates to the field of calendering machines, and in particular to a calendering machine that can detect the deviation of the tape during winding. Background Art

[0002] A calendering machine consists of two or more rollers arranged in a certain form, which can be divided into cold pressing and hot pressing. Cold pressing is applicable to materials that do not require heating, such as graphite films, graphite sheets, wave-absorbing materials, shielding materials, magnetic materials, non-ferrous metal materials, etc. Hot pressing is a machine that presses and extends rubber, silica gel or plastic into a film with a certain thickness and surface shape at a certain temperature, and can apply rubber to fiber cord fabric or steel cord fabric.

[0003] The utility model patent with the publication number CN210884492U discloses a forming machine for elastic tape forming, including a frame, a support frame slidably arranged on the frame, a winding roller rotatably arranged on the support frame, a deviation rectifying mechanism is arranged on the frame, and the deviation rectifying mechanism includes a driving device arranged on the frame and driving the support frame to slide, a detection frame arranged on the ground near the feeding side of the frame, two detection pieces horizontally and spaced apart on the detection frame and used for detecting the skew of the rubber tape and electrically connected to the driving device, and an adjusting device arranged on the detection frame.

[0004] This calendering machine detects whether the tape deviates through a photosensitive element. When using the photosensitive element for detection, the requirements for the environment are relatively high. There will be a large amount of dust and debris in general tape production workshops, which has a greater impact on the photosensitive element, resulting in poor detection effect of the photosensitive element. Utility Model Content

[0005] In order to reduce the environmental impact on the device for detecting tape deviation, this application provides a calendering machine that can detect the deviation of the tape during winding.

[0006] A calendering machine that can detect the deviation of the tape during winding provided by this application adopts the following technical solutions:

[0007] A calendering machine that can detect the deviation of the tape during winding includes a frame, a winding roller is rotatably connected to the frame, one end of the winding roller is provided with a winding motor for driving the winding roller to rotate, an installation rod parallel to the winding roller is arranged on the frame, two vertically upward detection rods are arranged on the installation rod, a detection port for the tape to pass through is formed between the two detection rods, and a rotating cylinder is sleeved on the detection rod.

[0008] By adopting the above technical solution, the tape passes through the detection port and then winds around the winding roller. When the tape shifts during winding, the tape will rub against the rotating cylinder, thereby driving the rotation of the rotating cylinder. The operator can detect whether the tape shifts when the calender winds the tape by observing the rotation of the rotating cylinder. This detection device uses a mechanical structure and is less affected by the environment.

[0009] Optionally, two first sliding blocks are slidably connected to the mounting rod along the length direction of the mounting rod, and the two detection rods are respectively arranged on the two first sliding blocks. A driving member for driving the first sliding block to move is provided on the frame.

[0010] By adopting the above technical solution, the widths of different tapes are different, and the sizes of the required detection ports are also different. The operator drives the first sliding block to move through the driving member, and the detection rod moves when the first sliding block moves, thereby adjusting the size of the detection port.

[0011] Optionally, the driving member includes a screw rod and a driving motor. The screw rod is rotatably connected to the frame and is arranged parallel to the mounting rod. The first sliding block is sleeved on the screw rod and is in bolt fit with the screw rod. The transmission shaft of the driving motor is coaxially connected to the screw rod.

[0012] By adopting the above technical solution, the driving motor drives the screw rod to rotate. When the screw rod rotates, it is in threaded fit with the first sliding block, thereby driving the first sliding block to move. This transmission method is relatively convenient to operate.

[0013] Optionally, the thread directions of the upper end of the screw rod on both sides of the midpoint of the screw rod are opposite.

[0014] By adopting the above technical solution, the thread directions of the upper end of the screw rod on both sides of the midpoint of the screw rod are opposite. The two first sliding blocks are respectively located at both ends of the screw rod, so that the screw rod can drive the two first sliding blocks to approach or move away from each other when rotating, enabling a single driving motor to drive the two first sliding blocks to approach or move away from each other simultaneously, which plays a role in saving equipment.

[0015] Optionally, the rotating cylinder is in threaded connection with the detection rod. When the rotating cylinder is driven to rotate by the tape, it moves upward. A horizontal detection plate is provided on the detection rod. A pressure sensor is provided at the lower end of the detection plate. The pressure sensor is electrically connected to a controller and sends the pressure value of the rotating cylinder on the detection plate to the controller. The controller is electrically connected to an alarm and controls the alarm to give an alarm when the pressure value is greater than the set value.

[0016] By adopting the above technical solution, when the rotating cylinder is driven by the tape to rotate, it will move upward and abut against the detection plate. When the pressure sensor detects the pressure of the rotating cylinder on the detection plate, it will send the pressure value to the controller. When the pressure value is greater than the set value, the controller controls the alarm to sound an alarm, reminding the operator that the tape has shifted.

[0017] Optionally, an installation groove is formed at the upper end of the first sliding block, the installation rod is arranged at the bottom of the installation groove, and a part of the rotating cylinder is exposed outside the installation groove.

[0018] By adopting the above technical solution, a part of the rotating cylinder is exposed outside the installation groove, so that the rotating cylinder is always in contact with the tape during the up and down movement, making the detection function more stable.

[0019] Optionally, a protective cylinder is sleeved outside the rotating cylinder. The protective cylinder is connected to the rotating cylinder through a bearing. A clamping block is arranged on the outer side wall of the rotating cylinder, and a clamping rod for clamping with the clamping block is arranged on the inner side wall of the protective cylinder. The clamping rod is rotatably connected to the protective cylinder, and a torsion spring for maintaining the clamping rod arranged along the circumferential direction of the protective cylinder is arranged at the connection between the clamping rod and the protective cylinder.

[0020] By adopting the above technical solution, the tape drives the protective cylinder to rotate, the protective cylinder drives the clamping rod to move, and when the clamping rod moves and is clamped with the clamping hole to drive the rotating cylinder to rotate, when the rotating cylinder rotates and moves upward to abut against the detection plate, it is more difficult for the rotating cylinder to rotate, the resistance of the clamping block to the clamping rod increases, so that the clamping rod no longer rotates and is not clamped with the clamping block, and the protective cylinder does not drive the rotating cylinder to rotate when it rotates, playing a role in protecting the rotating cylinder.

[0021] Optionally, a sliding groove parallel to the winding roller is formed on the frame. A second sliding block is slidably connected in the sliding groove. A cylinder for driving the second sliding block to move is arranged on the frame. An installation frame is arranged on the second sliding block, and the winding roller is rotatably connected to the installation frame.

[0022] By adopting the above technical solution, when the tape shifts, the operator drives the second sliding block to move through the cylinder, the second sliding block drives the installation frame to move, and the installation frame drives the winding roller to move to the required position, thereby reducing the shift of the tape.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the tape shifts during winding, the tape will rub against the rotating cylinder to drive the rotating cylinder to rotate. The operator can detect whether the tape shifts when the calender winds the tape by observing the rotation of the rotating cylinder. This detection device uses a mechanical structure and is less affected by the environment;

[0025] 2. When the drum is driven by the tape, it will move upward and contact the detection plate. When the pressure sensor detects the pressure of the drum on the detection plate, it sends the pressure value to the controller. When the pressure value is greater than the set value, the controller controls the alarm to sound an alarm to remind the operator that the tape has shifted. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a molding machine for elastic tape molding. Figure 1 A calender capable of detecting the deviation of an adhesive tape during winding includes a frame 1, a horizontal sliding groove 51 is provided on the frame 1, the sliding groove 51 is arranged perpendicular to the conveying direction of the adhesive tape, a second sliding block 52 is slidingly connected in the sliding groove 51 along the length direction of the sliding groove 51, a cylinder 54 for driving the second sliding block 52 to move is installed on the frame 1, a mounting frame 53 is installed on the upper end of the second sliding block 52, a winding roller 11 is rollingly connected to the mounting frame 53, the winding roller 11 is arranged parallel to the sliding groove 51, and the adhesive tape is wound on the winding roller 11.

[0033] Reference Figure 1 , Figure 2 as well asFigure 3 , a horizontal mounting rod 2 is fixedly connected to the frame 1. The mounting rod 2 is arranged in parallel with the winding roller 11. The mounting rod 2 and the winding roller 11 are arranged in sequence along the tape conveying direction. Two first sliding blocks 21 are slidably connected to the mounting rod 2 along the length direction of the mounting rod 2. A driving member 3 for driving the first sliding blocks 21 to move is installed on the frame 1. The driving member 3 includes a screw rod 32 and a driving motor 31. The screw rod 32 is rotatably connected to the frame 1 and is arranged in parallel with the mounting rod 2. The transmission shaft of the driving motor 31 is coaxially connected to the screw rod 32 to drive the screw rod 32 to rotate. The two first sliding blocks 21 are respectively sleeved on both ends of the screw rod 32 and are in threaded cooperation with the screw rod 32. The thread directions on both sides of the upper end of the screw rod 32 with the midpoint of the screw rod 32 as the demarcation point are opposite, so that the screw rod 32 can drive the two first sliding blocks 21 to approach or move away from each other when rotating, so that one driving motor 31 can drive the two first sliding blocks 21 to approach or move away from each other at the same time.

[0034] Refer to Figure 2 , Figure 3 and Figure 4 , an installation groove 22 is opened at the upper end of the first sliding block 21. A vertically upward detection rod 23 is fixedly connected to the bottom of the installation groove 22. The detection rod 23 is a threaded rod. A rotating cylinder 25 is sleeved outside the detection rod 23. The rotating cylinder 25 is in threaded cooperation with the detection rod 23. A protection cylinder 6 is sleeved outside the rotating cylinder 25. Both the upper and lower ends of the protection cylinder 6 are rotatably connected to the rotating cylinder 25 through bearings 7. A clamping block 43 is fixedly connected to the outer side wall of the rotating cylinder 25. A clamping rod 41 is rotatably connected to the inner side wall of the protection cylinder 6. The clamping rod 41 and the clamping block 43 are in a clamping position. A torsion spring 42 for maintaining the clamping rod 41 in the radial direction of the protection cylinder 6 is installed at the connection between the clamping rod 41 and the protection cylinder 6.

[0035] Refer to Figure 2 , Figure 3 and Figure 4 , a horizontal detection plate 26 is fixedly connected to the upper end of the detection rod 23. A pressure sensor 27 is installed at the lower end of the detection plate 26. The pressure sensor 27 is electrically connected to a controller 28. When the tape drives the protection cylinder 6 and the rotating cylinder 25 to rotate, the rotating cylinder 25 moves upward through the threaded cooperation with the detection rod 23. When the rotating cylinder 25 moves upward and touches the pressure sensor 27, the pressure sensor 27 sends the generated pressure value to the controller 28. The controller 28 is electrically connected to an alarm 29. When the pressure value is greater than the set value, the controller 28 controls the alarm 29 to give an alarm, thereby reminding the operator that the tape has a large deviation.

[0036] The implementation principle of a molding machine for elastic tape molding in an embodiment of the present application is as follows: when the tape deviates during the conveying process, it will contact the protective tube 6 and drive the protective tube 6 to rotate. When the protective tube 6 rotates, the clamping position of the clamping rod 41 and the clamping block 43 drives the rotating drum 25 to rotate. When the rotating drum 25 rotates, it moves upward and contacts the pressure sensor 27 and the detection plate 26, so that the pressure sensor 27 generates a pressure value. The pressure sensor 27 sends the generated pressure value to the controller 28. When the pressure value is greater than the set value, the controller 28 controls the alarm 29 to sound an alarm, thereby reminding the operator that the tape has a large deviation.

[0037] When the rotating drum 25 contacts the detection plate 26 , the resistance of the block 43 to the clamping rod 41 increases, causing the torsion spring 42 to bend, so that the clamping rod 41 is no longer blocked by the block 43 , so that the protection cylinder 6 can continue to rotate but stops rotating, thereby protecting the rotating drum 25 .

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
