Description
Technical Field
[0001] The utility model relates to the field of auxiliary components for producing transparent adhesive tapes, in particular to an adjustable winding device for producing transparent adhesive tapes. Background Art
[0002] Transparent tape is made from the original BOPP film, which is subjected to high-voltage corona treatment to make one side of the surface rough. Glue is then applied to the rough surface and then divided into small rolls through strips. In our daily life, we need to use transparent tape to fix and seal items such as paper and paper boxes.
[0003] Specifically in the production process of transparent tape, a winding device is required to fix the long strip of tape around the outer periphery of the core to facilitate subsequent transportation and sale. Since transparent tape needs to be sold to different groups of people, tapes of different sizes need to be customized according to customer requirements, and therefore the specifications of the cores required are also different. However, when the existing winding device fixes the core, it is not convenient to fix cores of different sizes, resulting in greater limitations in its use. At the same time, in the process of fixing the core, it is difficult to accurately control the degree of force applied when fixing the core. Since the core is usually a straight tube made of paper, it is easy to apply too little fixing force, resulting in the inability to stably fix the core, and it is easy to apply too much fixing force, resulting in damage to the core.

[0019] The adjustable winding device for producing transparent tape is used. Specifically, in the production process of transparent tape, when it is necessary to wind the tape around a core for use, the spacing between the core winding assembly and the core positioning assembly can be adjusted by driving the core winding assembly to move horizontally through the spacing adjustment assembly, and then cores of different widths and sizes can be clamped between the core winding assembly and the core positioning assembly. The fixing method of the core is simple and easy to implement, and the general use scope of the core winding assembly and the core positioning assembly is enriched. Specifically, in operation, the drive motor 2 is powered on by being electrically connected to an external power supply cable, and the drive motor 2 is powered on by the motor The second shaft drives the screw rod to rotate forward and reverse, and the screw rod can drive the nut seat to move back and forth laterally through the forward and reverse rotation of the screw rod, and then the spacing between the core winding assembly and the core positioning assembly can be expanded or reduced through the reciprocating movement of the nut seat. The spacing adjustment method is simple and easy to operate, and it is convenient to quickly fix the core between the core winding assembly and the core positioning assembly. When the core needs to be fixed, the screw rod is first rotated forward to expand the distance between the core winding assembly and the core positioning assembly, and then one end of the core opening is coaxially sleeved on the driven clamping block by comparing with the driven clamping block, and then the screw rod is reversed to reduce the distance between the core winding assembly and the core positioning assembly. The distance between the core positioning components, during this process, the active clamping block of the core winding component approaches the driven clamping block and enters from the opening at the other end of the core, and then cooperates with the driven clamping block to clamp and fix the core. At the same time, during this process, since the active clamping block of the core winding component and the driven clamping block of the core positioning component are both truncated cone-shaped clamping blocks and the two are symmetrically distributed, the core can be naturally coaxially fixed through the appearance of the active clamping block and the driven clamping block, and at the same time, the active clamping block and the driven clamping block are close to each other. The truncated cone shape can also be used to clamp cores of different diameters and sizes, further enriching the core winding. The general scope of use of the assembly and the core positioning assembly is that after the core is fixed, one end of the tape is guided and fixed on the outer periphery of the core, and then the drive motor 1 is powered on by being electrically connected to an external power supply cable, and the drive motor 1 drives the active turntable to rotate through the motor shaft 1. During the rotation, the active turntable drives the core to rotate and starts to wind the transparent tape around the outside of the core. After the winding is completed, the drive motor 1 is paused first, and then the active clamping block can be expanded again. The distance between the active clamping block and the driven clamping block can be expanded. After that, the wound core can be removed and the ongoing core can be installed for continued use. At the same time, in the process of the core winding assembly and the core positioning assembly approaching each other to clamp the core,The safety limit assembly can limit the minimum distance between the core winding assembly and the core positioning assembly, and then by limiting the minimum distance between the core winding assembly and the core positioning assembly, the clamping force of the core can be limited, thereby avoiding the situation where the fixing force is too small and the core cannot be stably fixed, and at the same time avoiding the situation where the fixing force is too large and the core is damaged. Specifically in operation, the core can be fixed with an appropriate force, and then the limit screw can be turned to make the inner end of the limit screw abut against the inner end of the matching hole. After the inner end of the limit screw contacts the inner end of the matching hole, the limit screw is kept from rotating and the limit nuts on both sides are pressed tightly against the two side surfaces of the fixed stand, so as to prevent the limit screw from naturally rotating and changing position. During the process, the minimum distance between the core winding assembly and the core positioning assembly can be limited by the abutment between the limit screw of the safety limit assembly and the bottom of the matching hole of the fixing rod. The distance limitation method is simple and easy to implement, which is convenient for limiting the distance between the core winding assembly and the core positioning assembly to a suitable distance and fixing the core with a suitable degree of force, and is convenient for repeatedly fixing the cores of the same specification, which is beneficial to improving the clamping and replacement efficiency of the cores. At the same time, the end position of the limit screw close to the matching hole can be adjusted by twisting the limit screw forward and reversely, and then the minimum distance between the core winding assembly and the core positioning assembly can be adaptively adjusted according to the different specifications of the fixed core, so that the minimum distance between the core winding assembly and the core positioning assembly can be adjusted to a suitable size to smoothly complete the fixation of the core.
[0020] The beneficial effects are as follows: 1. The utility model can adjust the spacing between the core winding assembly and the core positioning assembly by driving the spacing adjustment assembly to move the core winding assembly horizontally, and then can clamp cores of different widths and sizes between the core winding assembly and the core positioning assembly. The fixing method of the core is simple and easy to implement, and at the same time enriches the general use scope of the core winding assembly and the core positioning assembly;
[0021] 2. The active clamping block of the core winding assembly and the driven clamping block of the core positioning assembly are both truncated cone-shaped clamping blocks and are symmetrically distributed. Then, by bringing the active clamping block and the driven clamping block close to each other, the truncated cone-shaped shape can be used to clamp cores of different diameters and sizes, further enriching the general use range of the core winding assembly and the core positioning assembly;
[0022] 3. The screw rod can be rotated forward and reversely to drive the nut seat to move back and forth horizontally, and then the spacing between the core winding assembly and the core positioning assembly can be expanded or reduced by the nut seat moving back and forth horizontally. The spacing adjustment method is simple and easy to operate, and it is convenient to quickly fix the core between the core winding assembly and the core positioning assembly;
[0023] 4. The minimum distance between the core winding assembly and the core positioning assembly can be limited by the safety limit assembly, and then the clamping force of the core can be limited by limiting the minimum distance between the core winding assembly and the core positioning assembly, thereby avoiding the situation where the core cannot be stably fixed due to the small fixing force, and avoiding the situation where the core is damaged due to the large fixing force;
[0024] 5. The minimum distance between the core winding assembly and the core positioning assembly can be limited by the contact between the limit screw of the safety limit assembly and the bottom of the matching hole of the fixing rod. The distance limitation method is simple and easy to implement, which is convenient for limiting the distance between the core winding assembly and the core positioning assembly to a suitable distance and fixing the core with a suitable force, and is convenient for repeatedly fixing the core of the same specification, which is conducive to improving the clamping and replacement efficiency of the core;
[0025] 6. The end position of the limit screw close to the matching hole can be adjusted by turning the limit screw forward and reversely, and then the minimum distance between the core winding assembly and the core positioning assembly can be adaptively adjusted according to the different specifications of the fixed core, so that the minimum distance between the core winding assembly and the core positioning assembly can be adjusted to a suitable size to successfully fix the core.

The purpose of this arrangement is to allow the opening of one end of the core to be coaxially sleeved on the driven clamping block 401 in a manner of matching with the driven clamping block 401, thereby completing the positioning restriction of the opening at one end of the core.
[0043] See also Figure 1-Figure 7As shown, a spacing adjustment component 2 is installed on the other side of the top surface of the base 3, and the top of the spacing adjustment component 2 is fixedly connected to a core winding component 1 for driving the core to rotate to complete the winding operation. Specifically, the core winding component 1 includes a movable stand 105 and a drive motor 101. The movable stand 105 is vertically arranged above the other side of the top surface of the base 3 along the longitudinal direction, and the bottom surface of the movable stand 105 is connected to a part of the spacing adjustment component 2. The upper part of the movable stand 105 is laterally fixed with a drive motor 101 on the outer end surface of the opposite fixed stand 405, and the motor shaft 102 of the drive motor passes through the movable stand 105 in a transverse sliding fit manner. The active turntable 103 is coaxially fixed to the end of the motor shaft 102 close to the driven clamping block 401 through a fixing sleeve 106. Preferably, the fixing sleeve 106 is coaxially interference fit with the motor shaft 102, and the fixing sleeve 106 is welded to the end face of the active turntable 103. The active turntable 103 is coaxially fixed with an active clamping block 104 on the outer end face facing the driven clamping block 401, and the active clamping block 104 and the driven clamping block 401 are coaxial. The purpose of this arrangement is to make the active clamping block 104 close to the driven clamping block 401 and enter from the other end opening of the winding core, and then cooperate with the driven clamping block 401 to clamp and fix the winding core.
[0044] See also Figure 1-Figure 5As shown, part of the spacing adjustment component 2 is connected to the core positioning component 4, which is used to drive the core winding component 1 to move horizontally through the spacing adjustment component 2 to adjust the distance between it and the core positioning component 4, so that cores of different sizes can be clamped between the core winding component 1 and the core positioning component 4. Specifically, the spacing adjustment component 2 includes a mounting seat 202 and a second drive motor 201. The mounting seat 202 is vertically fixed to the side of the top surface of the base 3 away from the fixed stand 405 along the longitudinal direction. The outer side of the mounting seat 202 is laterally fixed with a second drive motor 201, and the motor shaft 203 of the second drive motor 201 passes through the mounting seat 202 in a transverse sliding fit. The end of the motor shaft 203 is coaxially fixed with a screw rod 208 through a coupling, and the other end of the screw rod 208 is connected to the inner ring of the bearing built into the second bearing seat 209.

Such an arrangement makes it easy to adjust the spacing between the core winding assembly 1 and the core positioning assembly 4 by driving the core winding assembly 1 to move horizontally through the spacing adjustment assembly 2, and then the cores of different widths and sizes can be clamped between the core winding assembly 1 and the core positioning assembly 4. Specifically, the screw rod 208 can be used to drive the nut seat 207 to move back and forth horizontally in a forward and reverse manner, and then the spacing between the core winding assembly 1 and the core positioning assembly 4 can be expanded or reduced by the nut seat 207 moving back and forth horizontally.
[0045] See also Figure 4-Figure 7 As shown, a safety limit assembly 5 is installed between the core winding assembly 1 and the core positioning assembly 4 for safely limiting the minimum distance between the core winding assembly 1 and the core positioning assembly 4. Specifically, the safety limit assembly 5 includes a fixed rod 505 and a limit screw 502. The fixed rod 505 is fixed laterally on the lower part of the inner end surface of the movable seat 105, and the lower part of the fixed seat 405 is engaged and interspersed with the limit screw 502 laterally. The limit screw 502 is coaxial with the center of the fixed rod 505 and the inner ends of the two are close to each other. With such an arrangement, the minimum distance between the core winding assembly 1 and the core positioning assembly 4 can be limited by the safety limit assembly 5, and then the degree of force applied to clamp the core can be limited by limiting the minimum distance between the core winding assembly 1 and the core positioning assembly 4.
[0046] See also Figure 1-Figure 4As shown, the core positioning assembly 4 and the core winding assembly are optimized as follows, specifically, the active clamping block 104 and the driven clamping block 401 are both truncated cone style clamping blocks, the small ends of the active clamping block 104 and the driven clamping block 401 are close to each other and are symmetrically distributed, and the active clamping block 104 and the driven clamping block 401 are both rubber blocks, and the large end diameters of the active clamping block 104 and the driven clamping block 401 are smaller than the outer diameters of the active turntable 103 and the driven turntable 402. The purpose of this arrangement is, firstly, that the core can be naturally coaxially fixed by the outer shape of the active clamping block 104 and the driven clamping block 401, and at the same time, the active clamping block 104 and the driven clamping block 401 are close to each other in such a way that the truncated cone shape can be used to clamp cores of different diameters.
[0047] See also Figure 1-Figure 2 As shown, the spacing adjustment component 2 is optimized as follows: a guide rod 205 is arranged in the horizontal direction between the mounting seat 202 and the fixed stand 405 at the position before and after the screw rod 208, and both ends of the guide rod 205 are respectively fixedly connected to the mounting seat 202 and the fixed stand 405 through a connecting sleeve 204, preferably the connecting sleeve 204 is welded to the surface of the mounting seat 202 and the fixed seat, and the ends corresponding to the connecting sleeve 204 and the guide rod 205 are coaxially interference fit, and the front and rear positions of the bottom surface of the movable stand 105 are vertically A guide seat 206 is fixed, and the guide seat 206 corresponds to the guide rod 205 respectively, and the guide rod 205 passes through the corresponding guide seat 206 in a lateral sliding manner. Such an arrangement makes it convenient for the movable seat 105 to move laterally along the screw rod 208 in the process of axial transverse movement of the movable seat 105 along the nut seat 207. The guide seat 206 slides laterally along the guide rod 205 to guide and correct the movement of the movable seat 105, so as to prevent the movable seat 105 from deviating and making the active clamping block 104 unable to correspond coaxially with the driven clamping block 401.
[0048] See also Figure 4-Figure 7As shown, the safety limit assembly 5 is optimized as follows. Specifically, a mating hole 504 is coaxially opened at the inner end of the fixing rod 505 near the limiting screw 502. The mating hole 504 is a blind hole, and the inner periphery of the mating hole 504 is coaxially slidably matched with the outer periphery of the limiting screw 502. The purpose of this arrangement is to limit the minimum spacing between the core winding assembly 1 and the core positioning assembly 4 by abutting the limiting screw 502 against the bottom of the mating hole 504 of the fixing rod 505, so as to limit the distance between the core winding assembly 1 and the core positioning assembly 4 to an appropriate distance and fix the core with an appropriate degree of force. At the same time, specifically with respect to the limit screw 502, a handle 501 is coaxially fixed to the outer end of the limit screw 502, and the limit screw 502 is coaxially engaged with the limit nut 503 at the positions on both sides of the fixed seat 405 when passing through the limit screw 502. The advantages of this arrangement are: first, it is easy to drive the limit screw 502 to rotate and adjust the position by holding the handle 501 and applying force. At the same time, when the limit screw 502 finishes rotating and adjusting the position, the limit nuts 503 on both sides are pressed against the two side surfaces of the fixed seat 405, so as to prevent the limit screw 502 from naturally rotating and changing its position.
[0049] By adopting the above structure, specifically in the production process of the transparent tape, when it is necessary to use the tape wound around the core, the spacing between the core winding assembly 1 and the core positioning assembly 4 can be adjusted by driving the core winding assembly 1 to move horizontally through the spacing adjustment assembly 2, and then the cores of different widths and sizes can be clamped between the core winding assembly 1 and the core positioning assembly 4. The fixing method of the core is simple and easy to implement, and at the same time, the general use scope of the core winding assembly 1 and the core positioning assembly 4 is enriched. Specifically in operation, the driving motor 201 is energized by being electrically connected to the external power supply cable, and the driving motor 201 drives the screw rod 208 to rotate forward and reversely through the motor shaft 203. The forward and reverse rotation of the screw rod 208 can The nut seat 207 can be driven to move back and forth laterally, and then the spacing between the core winding assembly 1 and the core positioning assembly 4 can be expanded or reduced by the nut seat 207 moving back and forth laterally. The spacing adjustment method is simple and easy to operate, and it is convenient to quickly fix the core between the core winding assembly 1 and the core positioning assembly 4. When the core needs to be fixed, the screw rod 208 is first rotated forward to expand the distance between the core winding assembly 1 and the core positioning assembly 4, and then one end of the core opening is coaxially sleeved on the driven clamping block 401 by comparing it with the driven clamping block 401, and then the screw rod 208 is reversed to reduce the distance between the core winding assembly 1 and the core positioning assembly 4. During this process, the active clamping block 104 of the core winding assembly 1 The active clamping block 104 of the core winding assembly 1 and the passive clamping block 401 of the core positioning assembly 4 are both truncated cone-shaped clamping blocks and are symmetrically distributed. The core can be naturally coaxially fixed by the appearance of the active clamping block 104 and the passive clamping block 401. At the same time, the active clamping block 104 and the passive clamping block 401 are close to each other, and the truncated cone-shaped appearance can be used to clamp cores of different diameters and sizes, further enriching the general use range of the core winding assembly 1 and the core positioning assembly 4. After the core is fixed, one end of the tape is guided and fixed on the core. The outer periphery of the core is then energized by the drive motor 101 which is electrically connected to the external power supply cable. The drive motor 101 drives the active turntable 103 to rotate through the motor shaft 102. The active turntable 103 drives the winding core to rotate during the rotation and starts to wind the transparent tape around the outside of the winding core. After the winding is completed, the drive motor 101 is paused first, and then the active clamping block 104 can be made to expand the distance with the driven clamping block 401 again. After that, the wound core can be removed and the ongoing core can be installed for continued use. At the same time, in the process of the core winding assembly 1 and the core positioning assembly 4 approaching each other to clamp the core, the minimum distance between the core winding assembly 1 and the core positioning assembly 4 can be limited by the safety limit assembly 5.Then, by limiting the minimum distance between the core winding assembly 1 and the core positioning assembly 4, the clamping and fixing force of the core can be limited, thereby avoiding the situation where the fixing force is too small and the core cannot be stably fixed, and at the same time avoiding the situation where the fixing force is too large and the core is damaged. Specifically, in operation, the core can be fixed with an appropriate force, and then the limit screw 502 is turned to make the inner end of the limit screw 502 abut against the inner end of the matching hole 504. After the inner end of the limit screw 502 contacts the inner end of the matching hole 504, the limit screw 502 is kept from rotating and the limit nuts 503 on both sides are pressed against the two side surfaces of the fixed seat 405, so as to prevent the limit screw 502 from naturally rotating and changing position. In the process of the core winding assembly 1 approaching the core positioning assembly 4 to clamp the core, the limit screw 502 is The way in which the screw 502 abuts against the bottom of the matching hole 504 of the fixing rod 505 can limit the minimum spacing between the core winding assembly 1 and the core positioning assembly 4. The spacing limitation method is simple and easy to implement, and is convenient for limiting the distance between the core winding assembly 1 and the core positioning assembly 4 to a suitable distance and fixing the core with a suitable degree of force, which is convenient for repeatedly fixing the cores of the same specification, and is beneficial to improving the clamping and replacement efficiency of the cores. At the same time, the end position of the limiting screw 502 close to the matching hole 504 can be adjusted by twisting the limiting screw 502 forward and reversely, and then the minimum spacing between the core winding assembly 1 and the core positioning assembly 4 can be adaptively adjusted according to the different specifications of the fixed core, so that the minimum spacing between the core winding assembly 1 and the core positioning assembly 4 can be adjusted to a suitable size to smoothly complete the fixing of the core.
