Description

Technical Field

[0001] The invention relates to the field of adhesive tape winding, and in particular to an adhesive tape winding device for automatic reel feeding and assembly. Background Art

[0002] The production process of adhesive tape mainly includes gluing, striping and winding. In the gluing process, the surface of the film substrate is glued to obtain the tape raw material, and the tape raw material is led to the winding station through several rollers for winding. During the tape transmission process, the tape is cut along the width direction. The cut tape strips are wound up to obtain multiple independent tape rolls.

[0003] In the tape winding process, a double-roller winder is usually used to wind the tape. The double-roller winder has two reels, one of which is used to wind the tape. After winding is completed, the other reel is replaced to continue the winding action. The reel that has completed tape winding will be replaced, unloaded manually, and a new reel will be reinstalled, and the operation will be cyclical.

[0004] In the prior art, the loading and unloading of the roll are all done manually. The tape winding process requires workers to be present throughout the process, and loading and unloading are required at regular intervals. The entire tape winding process is affected by human factors. If workers fail to load and unload materials in time, the tape winding process may stagnate and production efficiency may be reduced. Summary of the invention

[0005] To this end, the present invention provides a tape winding device with automatic roll loading and assembly, which effectively solves the technical problem in the prior art that the entire tape winding process is affected by human factors. If workers fail to load and unload materials in time, the tape winding process may stagnate and production efficiency may be reduced.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: a tape winding device for automatic roll feeding and assembly, comprising a pair of assembly frames, between which two opposite mounting seats are arranged;

[0007] Two reels are eccentrically mounted on the mounting seat, one of which performs a reeling action at a reeling position, and after the reeling is completed, the mounting seat rotates along the rotation direction of the reeling action to rotate the reel to the material changing position, and the other reel rotates to the reeling position;

[0008] A storage channel is provided on the assembly frame directly opposite to the material changing position, and a plurality of ends of the rolls to be loaded are stored in the storage channel. A discharge port is formed on the storage channel directly opposite to the mounting seat, and a limit valve is installed at the discharge port. The limit valve can adjust its own opening and closing state, so that when the limit valve is opened, one end of the roll can pass through the discharge port and be loaded onto the mounting seat;

[0009] A hollow assembly cavity is formed in the mounting seat, a pair of inlet valve blocks capable of automatically resetting are movably mounted at the opening of the assembly cavity facing the storage channel, and a bottom support frame is movably mounted at the opening of the assembly cavity away from the storage channel;

[0010] The feed valve block expands toward one side of the inside of the assembly cavity when the end of the roll is pressed downward, and the space between the feed valve blocks becomes larger, so that the end of the roll can pass through the gap and fall on the bottom support frame. The end of the roll is positioned in the assembly cavity by the supporting force of the bottom support frame. When the bottom support frame expands toward the side away from the assembly cavity, the end of the roll can separate from the assembly cavity under the action of gravity.

[0011] Furthermore, at the material replacement position, the assembly cavity forms an inlet facing the opening of the storage channel, and forms an outlet at the opening of the assembly cavity away from the storage channel;

[0016] When the column shaft falls into the assembly cavity, the column shaft is embedded in the shaft groove, and the first driving motor is driven to drive the column shaft to rotate through the driving shaft.

[0017] Furthermore, an inner cavity is provided in the assembly cavity, and the width of the inner cavity is greater than the width of the assembly cavity;

[0018] The feed valve block is rotatably installed on both sides of the inner cavity through a rotating shaft. The feed valve block is in an inverted L shape. A first torsion spring is arranged between the rotating shaft and the inner cavity. The first torsion spring is wound around the outer circumference of the rotating shaft, and one end of the first torsion spring is connected to the outer wall of the rotating shaft, and the other end is connected to the outer wall of the inner cavity.

[0020] Among them, when the bearing sleeve is pressed on the top of the feed valve block, the feed valve block is pressed to rotate toward one side of the inner part of the assembly cavity, the space between the feed valve blocks becomes larger, and the bearing sleeve passes through the feed valve blocks and falls onto the bottom support frame. Under the support of the bottom support frame, the outer wall of the bearing sleeve fits with the outer wall of the feed valve block.

[0021] Further, the bottom support frame includes a fixed shaft relatively mounted at the outlet and a second torsion spring arranged on the fixed shaft;

[0022] The second torsion spring is sleeved outside the fixed shaft, one end of the second torsion spring is connected to the outer wall of the fixed shaft, and the other end is connected to a connecting rod, the end of the connecting rod is connected to a support rod, and the support rod is curved and fits the outer wall of the bearing sleeve;

[0023] When changing materials, the reel to be loaded falls onto the mounting seat, and the bearing sleeve presses down the feed valve block. The feed valve block is pressed to rotate toward the inside of the assembly cavity and presses down the bearing sleeve on the support rod. The support rod is pressed to expand toward the side away from the assembly cavity, and resets after releasing the bearing sleeve to support the bearing sleeve newly placed on the support rod.

[0024] Wherein, the two opposite support rods respectively support different sides of the bearing sleeve, and the distance between the ends of the support rods is greater than the diameter of the connecting shaft.

[0025] Furthermore, the storage channel includes a first channel, a second channel, and a third channel arranged in sequence from the inside to the outside;

[0026] The column shaft is in sliding contact with the inner wall of the first groove, and when the column shaft slides to the end along the direction of the first groove, the column shaft is opposite to the shaft groove;

[0027] The bearing sleeve is slidably disposed in the second groove, and the connecting shaft is slidably disposed in the third groove;

[0031] The motor drives the micro belt drive through the driving wheel to drive the limit valve block to rotate;

[0032] A placement cavity that fits with the outer wall of the connecting shaft is formed between the limit valve blocks. When the limit valve block rotates toward the side of the mounting seat, the top opening of the placement cavity becomes smaller, and its bottom outlet becomes larger to allow the connecting shaft to pass through. When the limit valve block rotates away from the mounting seat, the bottom outlet of the placement cavity becomes smaller, and its top opening becomes larger to allow the connecting shaft at the top opening of the limit valve block to pass through and enter the placement cavity.

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a tape winding device for automatic roll feeding and assembly, including a pair of assembly frames 1, two opposite mounting seats 2 are arranged between the assembly frames 1, and each mounting seat 2 is correspondingly mounted on the corresponding assembly frame 1.

[0065] Two reels 3 are eccentrically mounted on the mounting seat 2, one of the reels 3 is in the reeling position for reeling, and after the reeling is completed, the mounting seat 2 rotates along the rotation direction of the reeling action to rotate the reel 3 to the material changing position, and the other reel 3 is rotated to the reeling position. After the loading and unloading of the reel 3 at the material changing position is completed, the above steps are repeated in a cycle to realize the automated reeling and loading and unloading process.

[0066] like Figure 5 and Figure 6As shown, a storage groove 4 is provided on the assembly frame 1 opposite to the material changing position, and the ends of several rolls 3 to be loaded are stored in the storage groove 4. A discharge port 5 is formed on the storage groove 4 opposite to the mounting seat 2, and a limit valve 6 is installed at the discharge port 5. The limit valve 6 can adjust its own opening and closing state, so that when the limit valve 6 is opened, the end of a roll 3 can pass through the discharge port 5 and be loaded onto the mounting seat 2.

[0067] A hollow assembly cavity 7 is formed in the mounting seat 2, and a pair of automatically resettable feed valve blocks 8 are movably installed at the opening of the assembly cavity 7 facing the storage groove 4, and a bottom support frame 9 is movably installed at the opening of the assembly cavity 7 away from the storage groove 4, and the bottom support frame 9 is used to support the end of the reel 3 entering the assembly cavity 7.

[0068] When the end of the reel 3 is pressed down, the feed valve block 8 expands toward one side of the inside of the assembly cavity 7, and the space between the feed valve blocks 8 becomes larger, so that the end of the reel 3 can pass through the gap and fall on the bottom support frame 9. The end of the reel 3 is positioned in the assembly cavity 7 by the supporting force of the bottom support frame 9. When the bottom support frame 9 expands toward the side away from the assembly cavity 7, the end of the reel 3 can separate from the assembly cavity 7 under the action of gravity.

[0069] In the present invention, a storage groove 4 is provided on the assembly frame 1, and the ends of a plurality of reels 3 to be loaded are stored in the storage groove 4. The ends of the reels 3 can be loaded into the assembly cavity 7 on the mounting seat 2 through the discharge port 5 at the end of the storage groove 4, and when the ends of the new reels 3 are loaded into the assembly cavity 7, the ends of the reels 3 originally in the assembly cavity 7 are squeezed out of the assembly cavity 7, thereby completing the automatic loading, assembly and unloading process of the reels 3;

[0070] Furthermore, when the end of the reel 3 is in the assembly cavity 7, the end of the reel 3 is stably positioned in the assembly cavity 7 by the supporting force, thereby improving the assembly stability.

[0071] In the present invention, Figure 7 , Figure 8 and Fig.13 As shown, both sides of the mounting seat 2 are provided with assembly cavities 7. At the material changing position, the assembly cavity 7 is opposite to the opening of the storage channel 4 to form an inlet 10, and the assembly cavity 7 is away from the opening of the storage channel 4 to form an outlet 11;

[0072] The feed valve block 8 is movably mounted at the inlet 10, and the bottom support frame 9 is movably mounted at the outlet 11;

[0073] In the winding position, the inlet 10 is located at a side away from the storage channel 4 , and the outlet 11 is located at a side close to the storage channel 4 .

[0074] That is to say, at the material changing position, the inlet 10 faces upward and the outlet 11 faces downward, the end of the new roll 3 can enter the inlet 10 under the action of gravity, and the end of the roll 3 that has completed winding can also be unloaded from the outlet 11 under the action of gravity; at the winding position, the inlet 10 faces downward and the outlet 11 faces upward, and the end of the roll 3 is stably fixed in the assembly cavity 7 under the action of gravity.

[0075] In the assembly cavity 7, the end of the reel 3 is not only stably assembled in the assembly cavity 7, but also needs to be driven to drive the reel 3 to rotate. The reel 3 rotates to achieve the winding action of the tape. To achieve the above purpose, the present invention also makes the following design, such as Figure 8 As shown, the end of the reel 3 is connected to a connecting shaft 12, and the end of the connecting shaft 12 is connected to a column shaft 13. The connecting shaft 12 is a cylindrical shaft structure, and the column shaft 13 is a rectangular parallelepiped shaft structure.

[0076] like Fig. 9 , Fig.10 and Fig.11 As shown, a first driving motor 14 is installed in the assembly cavity 7 , a driving shaft 15 is connected to the end of the first driving motor 14 , and a shaft groove 16 is formed on the driving shaft 15 .

[0077] When the column shaft 13 falls into the assembly cavity 7 , the column shaft 13 is embedded in the shaft groove 16 , and the first driving motor 14 is driven to drive the column shaft 13 to rotate through the driving shaft 15 .

[0078] Among them, the upper and lower positions of the column shaft 13 and the shaft groove 16 are exactly opposite. After the column shaft 13 falls into the assembly cavity 7, the column shaft 13 is just embedded in the shaft groove 16. When the column shaft 13 is embedded in the shaft groove 16, the first drive motor 14 can drive the column shaft 13 to rotate through the drive shaft 15, and also drive the connecting shaft 12 and the reel 3 to rotate. The rotation process of the reel 3 is mainly to realize the winding of the tape, that is, at the winding position, the first drive motor 14 is continuously driven.

[0079] In addition, at the material changing position, if the shaft groove 16 is not directly opposite to the storage groove 4 directly above, the direction of the shaft groove 16 can be adjusted by driving the first driving motor 14 to drive the driving shaft 15 to rotate, thereby ensuring that the column shaft 13 is directly opposite to the shaft groove 16.

[0080] In the present invention, in order to assemble the first drive motor 14 and other structures, the assembly cavity 7 includes different cavity parts, among which, Fig.12 As shown, an inner cavity 17 is provided in the assembly cavity 7 , and the width of the inner cavity 17 is greater than the width of the assembly cavity 7 . The inner cavity 17 is mainly used for assembling the inlet valve block 8 .

[0081] like Fig.12 , Fig.13 and Fig.14 As shown, the feed valve block 8 is rotatably installed on both sides of the inner cavity 17 through the rotating shaft 18. The feed valve block 8 can rotate downward around the rotating shaft 18. The feed valve block 8 is in an inverted L shape. A first torsion spring is arranged between the rotating shaft 18 and the inner cavity 17. The first torsion spring is wound around the outer periphery of the rotating shaft 18, and one end of the first torsion spring is connected to the outer wall of the rotating shaft 18, and the other end is connected to the outer wall of the inner cavity 17.

[0082] When the first torsion spring is in a natural state, the spacing between the inlet valve blocks 8 is in a minimum state. When the inlet valve block 8 is pressed and rotated downward, the spacing between the inlet valve blocks 8 gradually increases to allow the end of the reel 3 to pass through. During the downward rotation of the first torsion spring, the first torsion spring gradually deforms, and the inlet valve block 8 is also gradually affected by the elastic force generated by the deformation of the first torsion spring. After the end of the reel 3 completely passes through the inlet valve blocks 8, the first torsion spring can drive the inlet valve block 8 to reset.

[0083] In order to ensure that the feed valve block 8 will not rotate downward after the mounting seat 22 is rotated and flipped, a limit strip 25 can be provided on the inner wall of the inner cavity 17. At the material changing position, the limit strip 25 abuts against the top of the feed valve block 8. The limit strip 25 is used to prevent the feed valve block 8 from rotating upward. At the winding position, the limit strip 25 will be turned around and abut against the bottom of the feed valve block 8. At this time, the limit strip 25 prevents the feed valve block 8 from rotating downward.

[0084] In order to improve the stability of the reel 3 during the self-rotation and winding process, the present invention makes the following designs: Fig.13 and Fig.14 As shown, the outer sleeve of the connecting shaft 12 is provided with a bearing sleeve 19, and a plurality of steel balls 20 are embedded in the bearing sleeve 19 along the circumferential direction. An annular groove 21 is provided on the outer wall of the connecting shaft 12 corresponding to the position of the bearing sleeve 19, and the steel balls 20 are in rolling contact with the annular groove 21;

[0085] Among them, when the bearing sleeve 19 is pressed on the top of the inlet valve block 8, the inlet valve block 8 is pressed to rotate toward one side of the inside of the assembly cavity 7, the space between the inlet valve blocks 8 becomes larger, and the bearing sleeve 19 passes through the inlet valve blocks 8 and falls onto the bottom support frame 9. Under the support of the bottom support frame 9, the outer wall of the bearing sleeve 19 fits with the outer wall of the inlet valve block 8.

[0086] In the above embodiments, the bottom support frame 9 and the feed valve block 8 are mainly used to limit and fix the bearing sleeve 19 located therebetween. After the bearing sleeve 19 is fixed, the connecting shaft 12 and the reel 3 are driven to rotate by the first drive motor 14, so that the connecting shaft 12 can stably rotate inside the bearing sleeve 19, and the steel ball 20 can also roll relatively in the annular groove 21.

[0087] In the present invention, the support frame can not only limit and fix the bearing sleeve 19, but also adjust its own unfolding state to allow the bearing sleeve 19 to be detached. Specifically, the bottom support frame 9 includes a fixed shaft 91 relatively installed at the outlet 11 and a second torsion spring 92 arranged on the fixed shaft 91;

[0088] The second torsion spring 92 is sleeved outside the fixed shaft 91, one end of the second torsion spring 92 is connected to the outer wall of the fixed shaft 91, and the other end is connected to a connecting rod 93, and the end of the connecting rod 93 is connected to a supporting rod 94, and the supporting rod 94 is curved and fits the outer wall of the bearing sleeve 19;

[0089] When changing materials, the reel 3 to be loaded falls onto the mounting seat 2, and the bearing sleeve 19 presses down the feed valve block 8. The feed valve block 8 is pressed to rotate toward the inside of the assembly cavity 7 while pressing down the bearing sleeve 19 on the support rod 94. The support rod 94 is pressed to expand toward the side away from the assembly cavity 7, and resets after releasing the bearing sleeve 19 to support the bearing sleeve 19 newly entered on the support rod 94.

[0090] When in the material changing position, the feed valve block 8 is above the bottom support frame 9, and there is no bearing sleeve 19 between the support rod 94 and the feed valve block 8, the second torsion spring 92 is in a natural state. In the natural state, the support rod 94 is inclined toward one side of the feed valve block 8, and the connecting rod 93 is inclined upward. When the bearing sleeve 19 is loaded on the support rod 94, the bearing sleeve 19 presses down the support rod 94. Under the overall gravity of the reel 3, the second torsion spring 92 is deformed, the support rod 94 rotates downward, and gradually drives the connecting rod 93 to a horizontal state, or may gradually tend to tilt downward, but because the elastic force generated by the second torsion spring 92 itself is sufficient to resist the overall gravity of the reel 3, the connecting rod 93 will not be directly caused to tend to a vertical state under the downward pressure of the bearing sleeve 19.

[0091] Under the action of gravity, the top of the bearing sleeve 19 may not abut against the inner wall of the feed valve block 8. Then, after the mounting seat 2 is rotated 180°, the corresponding reel 3 is rotated to the winding position, and the support rod 94 is above the feed valve block 8. At this time, the bearing sleeve 19 falls on the feed valve block 8 under the action of gravity and fits with the inner wall of the feed valve block 8. The second torsion spring 92 is shifted to the top of the bearing sleeve 19. The second torsion spring 92 no longer needs to resist the overall gravity of the bearing sleeve 19 and the reel 3. Under the action of elastic force, the second torsion spring 92 is reset and drives the support rod 94 to remain in contact with the outer wall of the bearing sleeve 19. At this time, the bearing sleeve 19 is tightly fixed on the feed valve block 8 under the pressure of the support rod 94, and then the subsequent self-rotation and winding action of the reel 3 is performed.

[0092] After the winding is completed, the mounting seat 2 is rotated again until the reel 3 is driven to the material changing position, the limit valve 6 is opened, and the new reel 3 is unloaded. Its bearing sleeve 19 is also pressed down on the loading valve block. Under the action of pressure, the loading valve block rotates downward, and under the thrust of the loading valve block, the bearing sleeve 19 on the support rod 94 gradually moves downward, driving the support rod 94 to rotate downward, and the connecting rod 93 gradually tends to a vertical state. The support rod 94 no longer supports the bearing sleeve 19, and the bearing sleeve 19 falls through the support rod 94. After falling, the support rod 94 is quickly reset under the action of the second torsion spring 92 and supports the bearing sleeve 19 of the new reel 3.

[0093] The bearing sleeve 19 can be a square sleeve or a round sleeve, and the shape of the inner wall of the corresponding feeding valve block and the shape of the support rod 94 correspond to the shape of the outer wall of the bearing sleeve 19.

[0094] In order to avoid obstruction to the connecting shaft 12 from falling after the support rod 94 rotates, the following design is made: two opposite support rods 94 support different sides of the bearing sleeve 19 respectively, and the distance between the ends of the support rods 94 is greater than the diameter of the connecting shaft 12. When the bearing sleeve 19 falls, the connecting shaft 12 can directly pass through between the support rods 94.

[0095] In the present invention, a sufficient amount of rolls 3 can be stored in the storage groove 4 to achieve a longer period of automatic loading and unloading. The direction of the storage groove 4 can be curved or straight. If it is straight, the opening of the storage groove 4 faces upward, and the rolls 3 are placed directly inside to facilitate loading. If it is curved, the storage groove 4 is longer and can store more rolls 3.

[0096] In order to store the connecting shaft 12, the column shaft 13, and the bearing sleeve 19 respectively, the present invention makes the following design, such as Figure 3 As shown, the storage channel 4 includes a first channel 41, a second channel 42, and a third channel 43 which are arranged sequentially from the inside to the outside;

[0097] The column shaft 13 is in sliding contact with the inner wall of the first groove 41 . When the column shaft 13 slides to the end along the first groove 41 , the column shaft 13 is aligned with the shaft groove 16 .

[0098] The bearing sleeve 19 is slidably disposed in the second groove 42, and the connecting shaft 12 is slidably disposed in the third groove 43;

[0099] The width of the second groove 42 is greater than the widths of the first groove 41 and the second groove 42 .

[0100] Assuming that the storage groove 4 is in a vertical or inclined direction, the width of the first groove 41 is substantially the same as the width of the column shaft 13, so that the column shaft 13 can always slide in a vertical state, be fed in a vertical state and fall into the shaft groove 16;

[0101] Assuming that the storage groove 4 is in the shape of a curved arc, with its end portion vertically facing the material changing position, the width of the first groove 41 is slightly larger than the width of the column shaft 13, and at least two corners of the column shaft 13 contact the inner wall of the first groove 41, and the other side of the column shaft 13 contacts the inner wall of the other side of the first groove 41, so as to ensure that the column shaft 13 will not change direction to one side deviating from the direction of the first groove 41 when sliding in the storage groove 4, and also to ensure that the column shaft 13 faces the shaft groove 16 when unloading at the discharge port 5, so that the column shaft 13 falls in a vertical state and falls into the shaft groove 16 when unloading from the first groove 41.

[0102] like Figure 2 , Figure 5 and Figure 6 As shown, the position limiting invention is used to control the feeding of the reel 3. Specifically, the position limiting valve 6 includes a position limiting valve block 61 which is relatively arranged;

[0103] The inner wall of the first groove 41 is provided with an installation cavity 62, and the limit valve block 61 is installed in the installation cavity 62 through a movable shaft 63, and the movable shaft 63 is externally connected to a micro belt 64, and a driving wheel 65 is provided at the end of the micro belt 64, and the driving wheel 65 is externally connected to a motor 66;

[0104] The motor 66 drives the micro belt 64 through the driving wheel 65 to drive the limit valve block 61 to rotate;

[0105] A placement cavity 67 that fits with the outer wall of the connecting shaft 12 is formed between the limit valve blocks 61 .

[0106] When the limit valve block 61 rotates toward the mounting seat 2, the top opening of the placement cavity 67 becomes smaller, and the bottom outlet 11 thereof becomes larger to allow the connecting shaft 12 to pass through;

[0107] When the limit valve block 61 rotates away from the mounting seat 2 , the bottom outlet 11 of the placement chamber 67 becomes smaller and the top opening thereof becomes larger, so that the connecting shaft 12 at the top opening of the limit valve block 61 can pass through and enter the placement chamber 67 .

[0108] In the present invention, Figure 1 and Figure 2 , Figure 8 As shown, a circular cavity 22 is provided in the assembly frame 1 for the mounting seat 2 to move, and the discharge port 5 is connected to the circular cavity 22;

[0109] A second drive motor 23 is installed in the circular cavity 22 , and the mounting seat 2 is externally connected to the second drive motor 23 . The second drive motor 23 is driven to drive the mounting seat 2 to rotate, so as to adjust the relative positions of the two reels 3 .

[0110] In order to store the unloaded reels 3 , the present invention makes the following design: a unloading chute 24 is provided on the assembly frame 1 , the unloading chute 24 is directly opposite to the material changing position and is connected to the circular cavity 22 , and the connecting shaft 12 can slide in the unloading chute 24 .

[0111] The material discharge chute 24 can also be arranged to be curved, with its discharge end being horizontal. In addition, a material discharge platform can be arranged at the discharge end of the material discharge chute 24, and the material discharge roller can directly roll onto the material discharge platform.

[0112] In summary, the main implementation process of the present invention is:

[0113] like Fig.15 As shown, assuming that in the initial state, one of the reels 3 is reeling at the reeling position, and the other reel 3 is waiting for reeling at the material changing position. After the reeling is completed, as shown in FIG. Fig.16 and Fig.17 As shown, the mounting base 2 rotates along the rotation direction of the winding action to rotate the reel 3 to the material changing position, and the other reel 3 rotates to the winding position;

[0114] The limit valve 6 is opened, and the new reel 3 falls, and the end of the reel 3 falls into the assembly cavity 7, the column shaft 13 is embedded in the shaft groove 16, and the bearing sleeve 19 presses down the feed valve block 8. The feed valve block 8 is pressed to rotate toward the inside of the assembly cavity 7 and presses down the old bearing sleeve 19 on the support rod 94. The support rod 94 is pressed to expand toward the side away from the assembly cavity 7, and resets after releasing the bearing sleeve 19 to support the bearing sleeve 19 newly entered on the support rod 94;

[0115] After being released, the reel 3 is discharged into the discharge chute 24 and moves downward along the discharge chute 24 , completing a round of automatic loading, assembly and unloading of the reel 3 .

[0116] A plurality of conveying rollers are arranged at the upstream end of the tape winding device. The feeding roller provides the tape raw material, and the tape raw material is conveyed to the tape winding device through the conveying roller for the tape to be wound.

[0117] In actual application, a plurality of paper rolls are arranged at equal intervals on each reel 3, and the adhesive tape is wound on the paper rolls during the process of the reel 3 rotating and winding.

[0118] In addition, an automatic cutting structure should be provided above the reel 3. After the relative positions of the two reels 3 are adjusted and before the reels 3 are unloaded, the tape between the two reels 3 needs to be cut before unloading.

[0119] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
