Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically a winding device for producing PET strapping. Background Technology

[0002] PET strapping is a type of polyester strapping made from PET as the main raw material through extrusion and unidirectional stretching. After processing, PET strapping needs to be wound and wrapped, usually by a winding machine. Existing winding machines are the equipment used for winding PET strapping during processing. Winding machines facilitate stable support and rotation during winding, and at the same time, they make it easy to fix the ends of the PET strapping before winding. The initial state of the PET strapping ends is more stable during winding, improving the stability of the winding machine in fixing the ends of the PET strapping and the convenience of winding.

[0003] For example, patent application number CN202420733190.7 discloses a PET strapping rewinding machine, including a rewinding machine body. The rewinding machine body includes a support base, a motor, a rewinding roller, a rotating shaft, and a fixing cap. The motor is fixedly installed on one side of the top of the support base by bolts. The rotating shaft is rotatably connected to the end of the motor located on the other side of the top of the support base. The rewinding roller is engaged and installed on the outer surface of the rotating shaft. The fixing cap is rotatably fixed to the end of the rotating shaft. By designing a fixed installation mechanism, before the rewinding machine body operates to rewind the PET strapping, the end of the PET strapping passes through the inside of the locking hole. After engagement and installation, releasing the hand torque causes the compression spring to deform and drive the slide rod to slide inside the slide groove. When the slide rod elastically presses and slides, it drives the pressure plate to press tightly inside the pressure groove, and presses the end of the PET strapping tightly inside the pressure groove, which facilitates the fixed installation and rewinding of the end of the PET strapping, and makes the rewinding of the PET strapping end in the initial state more stable.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of directly pressing the end of the PET strapping onto the outer surface of the winding roller and continuing to rotate the winding roller to press the end of the PET strapping onto the surface, requiring the operator to operate with both hands simultaneously, making the operation of installing and winding the end of the PET strapping cumbersome and inconvenient for initial tight pressing and winding of the end of the PET strapping, thus affecting the fixation of the end and the convenience of winding when the winding machine is winding the PET strapping.

[0005] However, during use, users need to be next to the take-up roller to observe the total thickness of the packing tape being wound on the take-up roller to determine whether the take-up roller has wound enough. This makes it impossible for one user to manage multiple take-up machines at the same time, or to install electronic detection equipment on the take-up device to detect the current winding thickness, resulting in a higher cost for the take-up equipment. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a winding device for PET strapping production, which has the advantage of facilitating the detection of the current winding thickness. This solves the problems of requiring users to be next to the winding roller to observe the total thickness of the strapping wound on the current winding roller to determine whether the current winding roller has wound enough, which makes it impossible for one user to manage multiple winding devices at the same time, or the need to install electronic detection equipment on the winding device to detect the current winding thickness, resulting in high cost of the winding device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a winding device for producing PET strapping, comprising a winding machine and a winding roller. The top right side of the inner wall of the winding machine is movably connected to the right side of the winding roller. The output end of the winding machine is drivenly connected to the left side of the winding roller. A mounting frame is fixedly connected to the top right side of the winding machine. A mounting plate is provided on the left side of the mounting frame. A spring switch is fixedly connected to the left side of the bottom of the mounting plate. A force-bearing arc plate is provided at the bottom of the spring switch. A pressing component is fixedly connected to the top of the force-bearing arc plate. An audible and visual indicator is fixedly connected to the bottom of the inner wall of the winding machine. The spring switch is electrically connected to the audible and visual indicator and the winding machine via a wire. An adjusting component is movably connected to the left side of the top of the mounting frame. Limiting components are fixedly connected to the front and rear sides of the top of the force-bearing arc plate.

[0008] In a preferred embodiment of this invention, the adjusting component includes a screw, the top of which extends through to the left side of the top of the mounting bracket and is movably connected to the mounting bracket. The bottom of the screw surface is threadedly connected to the right side of the interior of the mounting plate. A scale groove is provided on the right side of the inner wall of the mounting bracket.

[0009] In a preferred embodiment of this utility model, the limiting component includes a limiting rod, the top of which is fixedly connected to the front and rear sides of the top of the force-bearing arc plate. Limiting grooves are provided on the left side of both the front and rear sides of the top of the mounting plate, and the inner wall of the limiting groove is slidably connected to the surface of the limiting rod.

[0010] As a preferred embodiment of this invention, a transmission block is fixedly connected to the top of the screw, and a protective pad is provided on the top of the pressing member.

[0011] In a preferred embodiment of this invention, a first Velcro fastener is fixedly connected to the bottom of the protective pad, a second Velcro fastener is attached to the bottom of the first Velcro fastener, and the bottom of the second Velcro fastener is fixedly connected to the top of the pressing member.

[0012] As a preferred embodiment of this utility model, the protective pad has a buckle groove on both the left and right sides, and the transmission block has an anti-slip groove on its surface. The anti-slip groove has a plurality of grooves and is distributed in a ring at equal intervals.

[0013] In a preferred embodiment of this invention, the top of the limiting rod is fixedly connected to a limiting disk, and the diameter of the limiting disk is larger than the diameter of the inner wall of the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a force-bearing arc plate, pushes the force-bearing arc plate upward as the total thickness of the packing strap increases during winding. Then, the force-bearing arc plate continuously pushes the pressing component upward, and when it moves to the maximum distance, it presses the spring switch. When the spring switch is pressed, it sends an electrical signal to turn on the audible and visual prompt and also turns off the winding machine. This solves the problem that users need to be next to the winding roller to observe the total thickness of the packing strap currently wound on the winding roller to determine whether the winding roller has wound enough, which makes it impossible for one user to manage multiple winding machines at the same time, or to install electronic detection equipment on the winding device to detect the current winding thickness, resulting in high cost of winding equipment. It achieves the effect of conveniently detecting the current winding thickness.

[0016] 2. This utility model, by setting an adjustment component, allows for different strapping winding capacities when the current winding machine is connected to winding rollers of different diameters. The user can rotate the screw, which connects to the mounting plate via a threaded connection, causing the screw to move the mounting plate up and down. This, in turn, moves the mounting plate up and down, causing the spring switch to adjust accordingly. Different spring switch heights represent different detectable heights, facilitating compatibility with winding rollers of different diameters. Furthermore, by comparing the height of the mounting plate with the corresponding scale groove during adjustment, the user can quickly adjust the mounting plate to the desired height.

[0017] 3. By setting a limiting component, this utility model can limit the rotation of the mounting plate by utilizing the sliding cooperation between the limiting rod and the limiting groove during the rotation of the screw, thus avoiding the direct rotation of the mounting plate when the screw rotates, and improving the stability when adjusting the mounting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the present invention provides a PET strapping production winding device, including a winding machine 1 and a winding roller 2. The top right side of the inner wall of the winding machine 1 is movably connected to the right side of the winding roller 2. The output end of the winding machine 1 is drivenly connected to the left side of the winding roller 2. A mounting frame 3 is fixedly connected to the top right side of the winding machine 1. A mounting plate 4 is provided on the left side of the mounting frame 3. A spring switch 5 is fixedly connected to the left side of the bottom of the mounting plate 4. A force-bearing arc plate 6 is provided at the bottom of the spring switch 5. A pressing component 7 is fixedly connected to the top of the force-bearing arc plate 6. A sound and light indicator 8 is fixedly connected to the bottom of the inner wall of the winding machine 1. The spring switch 5 is electrically connected to the sound and light indicator 8 and the winding machine 1 through a wire. An adjustment component 9 is movably connected to the left side of the top of the mounting frame 3. Limit components 10 are fixedly connected to the front and rear sides of the top of the force-bearing arc plate 6.

[0024] refer to Figure 1 The adjustment component 9 includes a screw 91, the top of which extends through to the left side of the top of the mounting bracket 3 and is movably connected to the mounting bracket 3. The bottom of the surface of the screw 91 is threadedly connected to the right side of the interior of the mounting plate 4. A scale groove 92 is provided on the right side of the inner wall of the mounting bracket 3.

[0025] As a technical optimization of this utility model, by setting the adjustment component 9, when the current winding machine 1 is connected to winding rollers 2 of different diameters, the winding capacity of the packing tape corresponding to the winding rollers 2 of different diameters is also different. At this time, the user can rotate the screw 91, and through the threaded connection between the screw 91 and the mounting plate 4, the screw 91 drives the mounting plate 4 to move up and down for adjustment. Then the mounting plate 4 will drive the spring switch 5 to move up and down. Different heights of the spring switch 5 represent different detectable heights, so as to adapt to the use of winding rollers 2 of different diameters. In addition, by comparing the height of the mounting plate 4 with the corresponding scale groove 92 during the up and down adjustment of the mounting plate 4, the user can quickly adjust the mounting plate 4 to the required height.

[0026] refer to Figure 2 The limiting component 10 includes a limiting rod 101. The top of the limiting rod 101 is fixedly connected to the front and rear sides of the top of the force-bearing arc plate 6. Limiting grooves 102 are provided on the left side of the front and rear sides of the top of the mounting plate 4. The inner wall of the limiting groove 102 is slidably connected to the surface of the limiting rod 101.

[0027] As a technical optimization of this utility model, by setting a limiting component 10, during the rotation of the screw 91, the limiting rod 101 and the limiting groove 102 can be used to limit the rotation of the mounting plate 4, thereby avoiding the screw 91 from directly driving the mounting plate 4 to rotate, and improving the stability when adjusting the mounting plate 4.

[0028] refer to Figure 1 A transmission block 11 is fixedly connected to the top of the screw 91, and a protective pad 12 is provided on the top of the pressing part 7.

[0029] As a technical optimization of this utility model, by setting a transmission block 11, the user can rotate the screw 91 by pinching the transmission block 11 when the screw 91 needs to be rotated, so that the transmission block 11 drives the screw 91 to rotate, giving the user a point of force that is easy to apply force. Furthermore, by setting a protective pad 12, the pressing part 7 makes contact with the spring switch 5 through the protective pad 12 when it applies pressure to the spring switch 5, thus avoiding damage to the spring switch 5 under long-term use.

[0030] refer to Figure 3 The bottom of the protective pad 12 is fixedly connected to a first Velcro 13, the bottom of the first Velcro 13 is attached to a second Velcro 14, and the bottom of the second Velcro 14 is fixedly connected to the top of the pressing member 7.

[0031] As a technical optimization of this utility model, by setting the first hook and loop fastener 13 and the second hook and loop fastener 14, when the protective pad 12 is damaged after long-term use and needs to be replaced, the user can tear off the protective pad 12, causing the first hook and loop fastener 13 to separate from the corresponding second hook and loop fastener 14. Then, the first hook and loop fastener 13 on the new protective pad 12 can be pasted with the corresponding second hook and loop fastener 14, thereby quickly installing the new protective pad 12.

[0032] refer to Figure 1 and Figure 2 The protective pad 12 has a buckle groove 15 on both the left and right sides, and the transmission block 11 has an anti-slip groove 16 on its surface. The anti-slip groove 16 has several grooves and is distributed in a ring at equal intervals.

[0033] As a technical optimization of this utility model, by setting the buckle groove 15, the user can apply force to the protective pad 12 by buckling the buckle groove 15 when the user needs to tear off the protective pad 12, giving the user a convenient point of force application. Furthermore, by setting the anti-slip groove 16, the friction between the user's hand and the transmission block 11 can be increased when the user rotates the transmission block 11, thus avoiding slippage.

[0034] refer to Figure 2 The top of the limiting rod 101 is fixedly connected to a limiting plate, and the diameter of the limiting plate is larger than the diameter of the inner wall of the limiting groove 102.

[0035] As a technical optimization of this utility model, by setting a limiting plate, the diameter of the limiting plate is larger than the diameter of the inner wall of the limiting groove 102, thereby limiting the maximum downward movement distance of the mounting plate 4 and preventing the limiting rod 101 from disengaging from the limiting groove 102 and thus failing to limit the mounting plate 4.

[0036] The working principle and usage process of this utility model are as follows: After connecting the strapping tape to the winding roller 2 and starting the winding machine 1 for winding, the total thickness of the strapping tape wound on the winding roller 2 will continuously increase. Meanwhile, the bottom of the force-bearing arc plate 6 remains in contact with the top of the strapping tape, causing the force-bearing arc plate 6 to move upwards as the total thickness of the strapping tape increases. Then, the force-bearing arc plate 6 will continuously push the pressing member 7 upwards. When the pressing member 7 moves to its maximum distance, it will press the spring switch 5. When the spring switch 5 is pressed, it will send an electrical signal to activate the audible and visual indicator 8 and shut down the winding machine 1. At this time, the audible and visual indicator 8 will produce a warning sound and a flashing indicator light to prompt the user to remove the fully wound winding roller 2 from the winding machine 1 for replacement. Simultaneously, shutting down the winding machine 1 can prevent excessive strapping tape from being wound on the winding roller 2. The winding machine 1 can be connected to winding rollers 2 of different diameters to... When in use, the winding capacity of the packing tape corresponding to the winding rollers 2 of different diameters is also different. At this time, the user can rotate the screw 91, which is connected to the mounting plate 4 by threads. The screw 91 drives the mounting plate 4 to move up and down for adjustment. Then the mounting plate 4 will drive the spring switch 5 to move up and down. Different heights of the spring switch 5 represent different detectable heights, so as to adapt to the use of winding rollers 2 of different diameters. During the up and down adjustment of the mounting plate 4, the user can quickly adjust the mounting plate 4 to the required height by comparing the height of the mounting plate 4 with the corresponding scale groove 92. During the rotation of the screw 91, the sliding cooperation between the limiting rod 101 and the limiting groove 102 can limit the rotation of the mounting plate 4, preventing the screw 91 from directly driving the mounting plate 4 to rotate, thus improving the stability of the adjustment of the mounting plate 4.

[0037] In summary, the PET strapping production winding device, by setting a force-bearing arc plate 6, pushes the force-bearing arc plate 6 upward as the total thickness of the strapping increases during winding. Then, the force-bearing arc plate 6 continuously pushes the pressing part 7 upward, and when it moves to the maximum distance, it presses the spring switch 5. When the spring switch 5 is pressed, it sends an electrical signal to turn on the audible and visual indicator 8 and also turns off the winding machine 1. This solves the problem that users need to be next to the winding roller to observe the total thickness of the strapping currently wound on the winding roller to determine whether the winding roller has wound enough, which makes it impossible for one user to manage multiple winding machines at the same time, or to install electronic detection equipment on the winding device to detect the current winding thickness, resulting in high cost of the winding equipment.
