Description

Technical Field

[0001] The invention relates to the field of adhesive tape auxiliary equipment, and in particular to an adhesive tape head-tail connection device. Background Art

[0002] Long films such as tapes are widely used in industry. Such products are usually rolled up, and when one roll is used up, a new roll is often needed. If the machine is shut down to start a new roll, this will reduce production efficiency when the time cycle is high. If the tape is to be infinitely long in theory, the head and tail of the two rolls of tape must be connected to ensure the continuity of the operation. In order to connect the head and tail of different tapes, the current market uses manual cutting and trimming of the head and tail of the tape, and then manual pasting of the edges. For high-value materials, the quality of manual cutting is difficult to control, and manual connection and pasting also have operational difficulties. Summary of the invention

[0003] The problem to be solved by the present invention is to provide a tape head-tail connection device to achieve the connection of different tapes with high efficiency and high strength.

[0004] In order to solve the above problems, the present invention provides a tape head-to-tail connection device. In order to achieve the above purpose, the technical solution adopted by the present invention to solve its technical problems is:

[0005] A tape head-to-tail connection device comprises: a tape adsorption mechanism, which uses negative pressure suction to adsorb the lower surfaces of a first tape and a second tape, the tape adsorption mechanism comprises a first adsorption area for adsorbing the tail of the first tape, and also comprises a second adsorption area for adsorbing the head of the second tape, the first adsorption area has a translational freedom to approach or move away from the second adsorption area, and the center lines of the first tape on the first adsorption area and the second tape on the second adsorption area coincide with the same spatial straight line; a cutting mechanism, which is located above the tape adsorption mechanism and has a vertical lifting freedom, and the cutting mechanism includes The invention comprises a first cutter and a second cutter for cutting the first tape and the second tape respectively, the extending directions of the blades of the first cutter and the second cutter are parallel to each other and form an acute angle with the center line of the first tape, the first cutter and the second cutter are both single-sided blades, and the blade surfaces of the first cutter and the second cutter are facing or facing away from each other; a reinforcing tape mechanism is located above the tape adsorption mechanism, the reinforcing tape mechanism includes a reinforcing tape led out from a reinforcing tape reel, the reinforcing tape is attached to and connected to the tail of the first tape and the head of the second tape, and a pressing block is provided above the reinforcing tape to press the reinforcing tape downward.

[0006] The beneficial effects of adopting the above technical solution are: it can realize the connection between the front and rear rolls of tape, save materials, and theoretically provide infinitely long tape, providing conditions for the continuous operation of production equipment. The ends of the front and rear rolls of tape are cut into oblique ends, and then a layer of reinforcing tape is glued and covered on the oblique ends as a connection to realize the connection between the front and rear tapes. The design of the oblique end edge can extend the length of the dividing line along the length direction of the tape, thereby dispersing the relatively weak dividing line along the length direction of the tape to avoid weak points in structural strength. The first adsorption area and the second adsorption area use their own suction force to absorb the tail of the first tape and the head of the second tape respectively to prevent these parts from swinging disorderly, so as to facilitate subsequent cutting and connection operations. The blades of the first cutter and the second cutter are different, which results in the positional relationship between the first cutter and the first tape being essentially the same as the positional relationship between the second cutter and the second tape, that is, the blade faces are facing the same. In this way, after each cutter has cut its own tape, the tape may undergo slight natural deformation after being cut and contacted. Because the blade faces have the same relationship, this deformation is also mirror-symmetrical, so it is convenient for the subsequent connection of the first tape and the second tape. The first adsorption area and the second adsorption area are separated first to facilitate the respective operations of the first cutter and the second cutter and the blanking of the scraps. Then the first adsorption area and the second adsorption area are close to each other, so that the first tape and the second tape after cutting are butted against each other. The lower pressing block squeezes the reinforcing tape downward and applies enough force to allow the first tape, the second tape, and the reinforcing tape to adhere to each other. The entire equipment is free from manual operation, and efficiency and quality are guaranteed.

[0007] As a further improvement of the present invention, one side of the lower pressing block is provided with a third cutter for cutting the reinforcing tape. The third cutter is fixed to the lower pressing block by a fifth vertical cylinder. The bottom of the third cutter is a blade tip, and a plumb line passing through the blade tip intersects with a center line of the reinforcing tape on the lower pressing block. The first tape on the first adsorption area and the second tape on the second adsorption area are arranged horizontally, and the blade extension direction of the first cutter and the second cutter is horizontal.

[0008] The beneficial effect of adopting the above technical solution is that the third cutter is used to periodically cut the reinforcing tape into sections. It is convenient for each section of the reinforcing tape to connect the first tape and the second tape. Each time the cutting is performed, the tip of the third cutter first penetrates the center of the reinforcing tape, rather than one side of the reinforcing tape, so that the reinforcing tape can be prevented from deviating due to force during cutting.

[0009] As a further improvement of the present invention, a movable block is assembled at the bottom of the lower pressing block through a compression spring, the movable block has an adsorption hole in contact with the back of the reinforcing tape, and the adsorption hole is connected to a vacuum generator; the side of the movable block also has a winding wheel.

[0010] The beneficial effect of adopting the above technical solution is that: due to the compression spring, the movable block has elastic potential energy, and does not have hard contact with the reinforcing tape, thereby preventing damage to the reinforcing tape, the first adsorption area, and the second adsorption area when pressing down. The adsorption hole can use the negative pressure adsorption force to make the lightweight reinforcing tape close to the bottom of the movable block, ensuring that the reinforcing tape moves with the movable block.

[0011] As a further improvement of the present invention, a base plate is fixed to the top of the lower pressure block by a first vertical cylinder, and a pneumatic clamp for clamping the reinforcing tape is movably mounted on the base plate. The pneumatic clamp has horizontal reciprocating translation freedom, the pneumatic clamp is provided with a rack, and the base plate is provided with a gear in contact with the rack.

[0012] The beneficial effect of adopting the above technical solution is that the pneumatic clamp is responsible for periodically pulling out a section of reinforcing tape, and the horizontal movement of the pneumatic clamp is controlled by a gear rack. At the same time, it has the function of stopping at any time, which is convenient for controlling the length of the reinforcing tape pasted each time.

[0013] As a further improvement of the present invention, the first adsorption area is connected to the first horizontal cylinder, the spatial position of the second adsorption area is fixed, the first adsorption area and the second adsorption area are arranged in mirror images of each other, and the first adsorption area and the second adsorption area each have two parallel side blocks, and a linear groove for accommodating the first adhesive tape or the second adhesive tape is formed between the two side blocks, and the bottom of the linear groove has an adsorption hole.

[0014] The beneficial effects of adopting the above technical solution are: using a first horizontal cylinder to achieve the first adsorption area and the second adsorption area to move closer to and farther from each other, reducing equipment costs. The linear groove formed by the retaining block can accommodate the first adhesive tape and the second adhesive tape to prevent the first adhesive tape and the second adhesive tape from swinging at will. The adsorption hole allows the light-weight first adhesive tape and the second adhesive tape to be attached to the bottom of the linear groove, which is convenient for operation.

[0015] As a further improvement of the present invention, the facing ends of the side blocks of the first adsorption zone and the second adsorption zone are provided with a gradually decreasing slope surface, and the side blocks themselves are vertically penetrated with waist-shaped holes, and the length direction of the waist-shaped holes is perpendicular to the direction of the linear grooves.

[0016] The beneficial effects of adopting the above technical solution are: the slope surface facilitates the docking of the first tape and the second tape, avoids damaging the first tape and the second tape from the side, and also facilitates the first tape and the second tape to be quickly attached to the bottom of the linear groove. The waist-shaped hole facilitates fine-tuning the width of the linear groove to match the width of the first tape and the second tape.

[0017] As a further improvement of the present invention, a tension wheel and a pair of clamping wheels are also installed on the base plate. The reinforcing tape led out from the reinforcing tape reel contacts the tension wheel, the clamping wheel and the pneumatic clamp in sequence. The pneumatic clamp and the clamping wheel are at the same horizontal height. When the pneumatic clamp moves to the extreme position away from the clamping wheel, the pneumatic clamp and the clamping wheel are located on both sides of the lower pressure block.

[0018] The beneficial effects of adopting the above technical solution are: the elastic wheel can keep the reinforcing tape at a certain tension to ensure the smooth transmission of the reinforcing tape. The clamping wheel can limit the up and down displacement of the end of the reinforcing tape to prevent it from swinging disorderly. Each time a horizontal section of reinforcing tape is pulled out between the pneumatic clamp and the clamping wheel, it is convenient for the third cutter to cut this section of reinforcing tape, and it is also convenient for the pressing block to press down and stick this section of reinforcing tape.

[0019] As a further improvement of the present invention, the second tape is connected to a second tape reel at the end facing away from the second adsorption area, and several second tape reels are coaxially arranged. All second tape reels are arranged in a storage box, and the bottom of the storage box is connected to a bottom plate through a second horizontal screw rod, and the axis of the second horizontal screw rod is parallel to the axis of the second tape reel.

[0020] The beneficial effect of adopting the above technical solution is that the second tape reel can provide a large amount of second tape. When one second tape reel is used up, the entire storage box can be moved axially appropriately so that another second tape reel will be aligned with the position, and the overall feeding efficiency is high.

[0021] As a further improvement of the present invention, a lifting frame is fixed on the bottom plate, the lifting frame is connected to the top plate through a first horizontal screw rod, the top of the first vertical cylinder is fixed to the top plate, and the first cutter and the second cutter are fixed to the top plate through a second vertical cylinder and a third vertical cylinder respectively.

[0022] The beneficial effect of adopting the above technical solution is that the lifting frame provides conditions for fixing each device to a certain height, and the pressing block can move horizontally synchronously with the first cutter and the second cutter.

[0023] As a further improvement of the present invention, a blanking box is provided below between the first adsorption area and the second adsorption area; a three-degree-of-freedom manipulator is also fixed on the bottom plate, and the three-degree-of-freedom manipulator includes a second horizontal cylinder, a fourth vertical cylinder, and a fifth horizontal cylinder which are perpendicular to each other.

[0024] The beneficial effect of adopting the above technical solution is that the blanking box is used to collect the trimmed and cut scraps of the first tape and the second tape. The three-degree-of-freedom manipulator can have multiple uses. For example, a holding mechanism is added to the end of the three-degree-of-freedom manipulator to temporarily clamp the end of the second tape, which can avoid manual operation.

A pressing block 29 is provided above the reinforcing tape 57 to press the reinforcing tape 57 downward.

[0045] The beneficial effects of adopting the above technical solution are: it can realize the connection between the front and rear rolls of tape, save materials, and theoretically provide infinitely long tape, providing conditions for the continuous operation of production equipment. The ends of the front and rear rolls of tape are cut into oblique ends, and then a layer of reinforcing tape is glued and covered on the oblique ends as a connection to realize the connection between the front and rear tapes. The design of the oblique end edge can extend the length of the dividing line along the length direction of the tape, thereby dispersing the relatively weak dividing line along the length direction of the tape to avoid weak points in structural strength. The first adsorption area and the second adsorption area use their own suction force to absorb the tail of the first tape and the head of the second tape respectively to prevent these parts from swinging disorderly, so as to facilitate subsequent cutting and connection operations. The blades of the first cutter and the second cutter are different, which results in the positional relationship between the first cutter and the first tape being essentially the same as the positional relationship between the second cutter and the second tape, that is, the blade faces are facing the same. In this way, after each cutter has cut its own tape, the tape may undergo slight natural deformation after being cut and contacted. Because the blade faces have the same relationship, this deformation is also mirror-symmetrical, so it is convenient for the subsequent connection of the first tape and the second tape. The first adsorption area and the second adsorption area are separated first to facilitate the respective operations of the first cutter and the second cutter and the blanking of the scraps. Then the first adsorption area and the second adsorption area are close to each other, so that the first tape and the second tape after cutting are butted against each other. The lower pressing block squeezes the reinforcing tape downward and applies enough force to allow the first tape, the second tape, and the reinforcing tape to adhere to each other. The entire equipment is free from manual operation, and efficiency and quality are guaranteed.

[0046] In some other embodiments of the present invention, one side of the lower pressing block 29 is provided with a third cutter 59 for cutting the reinforcing tape 57. The third cutter 59 is fixed to the lower pressing block 29 by a fifth vertical cylinder 60. The bottom of the third cutter 59 is a blade tip, and a plumb line passing through the blade tip intersects with a center line of the reinforcing tape 57 on the lower pressing block 29. The first tape 4 on the first adsorption area 27 and the second tape 56 on the second adsorption area 28 are arranged horizontally, and the blade extension direction of the first cutter 25 and the second cutter 26 is horizontal.

[0047] The beneficial effect of adopting the above technical solution is that the third cutter is used to periodically cut the reinforcing tape into sections. It is convenient for each section of the reinforcing tape to connect the first tape and the second tape. Each time the cutting is performed, the tip of the third cutter first penetrates the center of the reinforcing tape, rather than one side of the reinforcing tape, so that the reinforcing tape can be prevented from deviating due to force during cutting.

[0048] In some other embodiments of the present invention, the bottom of the lower pressure block 29 is equipped with a movable block 35 through a compression spring 36. The movable block 35 has an adsorption hole 41 that contacts the back side of the reinforcing tape 57. The adsorption hole 41 is connected to a vacuum generator. The side of the movable block 35 also has a winding wheel 37.

[0049] The beneficial effect of adopting the above technical solution is that: due to the compression spring, the movable block has elastic potential energy, and does not have hard contact with the reinforcing tape, thereby preventing damage to the reinforcing tape, the first adsorption area, and the second adsorption area when pressing down. The adsorption hole can use the negative pressure adsorption force to make the lightweight reinforcing tape close to the bottom of the movable block, ensuring that the reinforcing tape moves with the movable block.

[0050] In some other embodiments of the present invention, a base plate 52 is fixed to the top of the lower pressing block 29 by a first vertical cylinder 38, and a pneumatic clamp 33 is movably mounted on the base plate 52 for clamping the reinforcing tape 57. The pneumatic clamp 33 has horizontal reciprocating translation freedom, and a rack 34 is provided on the pneumatic clamp 33. The base plate 52 has a gear in contact with the rack 34.

[0051] The beneficial effect of adopting the above technical solution is that the pneumatic clamp is responsible for periodically pulling out a section of reinforcing tape, and the horizontal movement of the pneumatic clamp is controlled by a gear rack. At the same time, it has the function of stopping at any time, which is convenient for controlling the length of the reinforcing tape pasted each time.

[0052] In some other embodiments of the present invention, the first adsorption area 27 is connected to the first horizontal cylinder 45, the second adsorption area 28 is fixed in spatial position, the first adsorption area 27 and the second adsorption area 28 are arranged in mirror image with each other, and the first adsorption area 27 and the second adsorption area 28 are provided with two parallel side blocks 39, and a straight groove 40 for accommodating the first adhesive tape 4 or the second adhesive tape 56 is formed between the two side blocks 39, and the bottom of the straight groove 40 is provided with an adsorption hole 41.

[0053] The beneficial effects of adopting the above technical solution are: using a first horizontal cylinder to achieve the first adsorption area and the second adsorption area to move closer to and farther from each other, reducing equipment costs. The linear groove formed by the retaining block can accommodate the first adhesive tape and the second adhesive tape to prevent the first adhesive tape and the second adhesive tape from swinging at will. The adsorption hole allows the light-weight first adhesive tape and the second adhesive tape to be attached to the bottom of the linear groove, which is convenient for operation.

[0054] In other embodiments of the present invention, the facing ends of the side blocks 39 of the first adsorption zone 27 and the second adsorption zone 28 have a slope surface 42 with gradually decreasing heights, and the side blocks 39 themselves are vertically penetrated by waist-shaped holes 43, and the length direction of the waist-shaped holes 43 is perpendicular to the direction of the straight groove 40.

[0055] The beneficial effects of adopting the above technical solution are: the slope surface facilitates the docking of the first tape and the second tape, avoids damaging the first tape and the second tape from the side, and also facilitates the first tape and the second tape to be quickly attached to the bottom of the linear groove. The waist-shaped hole facilitates fine-tuning the width of the linear groove to match the width of the first tape and the second tape.

[0056] In some other embodiments of the present invention, a tension wheel and a pair of clamping wheels 31 are also installed on the base plate 52. The reinforcing tape 57 led out from the reinforcing tape reel 30 contacts the tension wheel, the clamping wheel 31 and the pneumatic clamp 33 in sequence. The pneumatic clamp 33 and the clamping wheel 31 are at the same horizontal height. When the pneumatic clamp 33 moves to the extreme position away from the clamping wheel 31, the pneumatic clamp 33 and the clamping wheel 31 are located on both sides of the lower pressure block 29.

[0057] The beneficial effects of adopting the above technical solution are: the elastic wheel can keep the reinforcing tape at a certain tension to ensure the smooth transmission of the reinforcing tape. The clamping wheel can limit the up and down displacement of the end of the reinforcing tape to prevent it from swinging disorderly. Each time a horizontal section of reinforcing tape is pulled out between the pneumatic clamp and the clamping wheel, it is convenient for the third cutter to cut this section of reinforcing tape, and it is also convenient for the pressing block to press down and stick this section of reinforcing tape.

All second tape reels 32 are arranged in a storage box 54, and the bottom of the storage box 54 is connected to the bottom plate 24 through a second horizontal screw rod 48, and the axis of the second horizontal screw rod 48 is parallel to the axis of the second tape reel 32.

[0059] The beneficial effect of adopting the above technical solution is that the second tape reel can provide a large amount of second tape. When one second tape reel is used up, the entire storage box can be moved axially appropriately so that another second tape reel will be aligned with the position, and the overall feeding efficiency is high.

[0060] In some other embodiments of the present invention, a lifting frame 55 is fixed on the bottom plate 24, the lifting frame 55 is connected to the top plate 53 through the first horizontal screw rod 44, the top of the first vertical cylinder 38 is fixed to the top plate 53, and the first cutter 25 and the second cutter 26 are fixed to the top plate 53 through the second vertical cylinder 46 and the third vertical cylinder 47 respectively.

[0061] The beneficial effect of adopting the above technical solution is that the lifting frame provides conditions for fixing each device to a certain height, and the pressing block can move horizontally synchronously with the first cutter and the second cutter.

[0062] In some other embodiments of the present invention, a blanking box 58 is provided below the first adsorption area 27 and the second adsorption area 28; a three-degree-of-freedom manipulator is also fixed on the bottom plate 24, and the three-degree-of-freedom manipulator includes a second horizontal cylinder 49, a fourth vertical cylinder 50, and a fifth horizontal cylinder 51 which are perpendicular to each other.

[0063] The beneficial effect of adopting the above technical solution is that the blanking box is used to collect the trimmed and cut scraps of the first tape and the second tape. The three-degree-of-freedom manipulator can have multiple uses. For example, a holding mechanism is added to the end of the three-degree-of-freedom manipulator to temporarily clamp the end of the second tape, which can avoid manual operation.

[0064] The first adhesive tape 4 also passes through a motion-static control mechanism, which is fixed on the bottom plate.

[0065] The dynamic and static control mechanism includes: a discharge wheel group 1, which is provided with a pair of pressure wheels respectively contacting the two sides of the first adhesive tape 4; a feed wheel group 3, which is provided with a lifting wheel 9 and a driving wheel 10 respectively contacting the two sides of the first adhesive tape 4, the driving wheel 10 contacts and drives the first adhesive tape 4 to be transmitted, and the lifting wheel 9 has a linear degree of freedom to approach or move away from the driving wheel 10; a storage wheel group 2, which is arranged between the discharge wheel group 1 and the feed wheel group 3, and the storage wheel group 2 includes a row of upper driven wheels 7 arranged horizontally, and the upper driven wheels 7 are arranged at intervals and fixed in space A first vertical slide rail 13 is provided below the upper driven wheel 7, and the first vertical slide rail 13 is equipped with a lifting beam 14 with lifting freedom, and a plurality of lower driven wheels 8 are arranged at horizontal intervals along the upper edge of the lifting beam 14; the height of the upper driven wheel 7 is higher than the discharge wheel group 1 and the feed wheel group 3, and the first adhesive tape 4 connected to the discharge wheel group 1 and the feed wheel group 3 first contacts with the upper driven wheel 7, and the number of upper driven wheels 7 is one more than the number of lower driven wheels 8, and the first adhesive tape 4 contacts alternately between the upper driven wheel 7 and the lower driven wheel 8 in the storage wheel group 2.

[0066] The beneficial effects of adopting the above technical solution are: the tape transmitted from the end of the discharge wheel group is used to connect with the equipment, and the equipment is fed continuously and uninterruptedly to ensure that the equipment does not stop. The tape at the end of the feed wheel group can be stationary for a short period of time, which is convenient for cutting or connecting the tape. When the tape here needs to be stationary, the driving wheel stops rotating, and the lifting wheel approaches the driving wheel to clamp the tape here together to achieve the stationary state of the tape here. The control of the tape in and out during this entire stage is controlled by the storage wheel group. The lifting beam is adaptively lifted as the tape decreases, and the overall length of the tape wound in the storage wheel group becomes shorter to ensure that there is enough tape for continuous feeding. By utilizing the deadweight of the lifting beam and the multiple S-shaped paths formed by the upper and lower driven wheels, the storage wheel group can store a considerable length of tape for a long time without getting stuck. The lifting beam will only rise when the tape is not evenly fed in and out. This also ensures that the long tape in the storage wheel group can be shrunk into a smaller space, ensuring the overall smoothness of the tape. There is one more upper driven wheel to ensure that the tape contacts the storage wheel group before the upper driven wheel, ensuring that the lifting beam is suspended by the tape as a whole.

[0067] In other embodiments of the present invention, the spacing between adjacent upper driven wheels 7 is equal and equal to the spacing between adjacent lower driven wheels 8, the diameters of the upper driven wheels 7 and the lower driven wheels 8 are equal, and the portion of the first tape 4 that is commonly circumscribed between the upper driven wheels 7 and the lower driven wheels 8 is parallel to the vertical direction.

[0068] The beneficial effect of adopting the above technical solution is that it ensures that the personnel can sense how much length of the tape has been transmitted through the height difference of the lifting beam, and at the same time, the rolling friction force of the tape during the entire transmission process is relatively uniform and easier to control. The area of ​​the tape contacted by the upper driven wheel and the lower driven wheel will not change due to the change of the height of the lifting beam.

[0069] In some other embodiments of the present invention, the center of mass of the lifting beam 14 and the lower driven wheel 8 as a whole is located on the center line of the first vertical slide rail 13 .

[0070] The beneficial effect of adopting the above technical solution is that the lifting beam is not easily skewed during vertical movement.

[0071] In some other embodiments of the present invention, a plurality of weights are detachably connected to the lifting beam 14 .

[0072] The beneficial effect of adopting the above technical solution is that the weights can adjust the deadweight of the lifting beam to ensure that the lifting beam can fall with its own weight to adapt to tapes with different physical properties. If the tape material is harder, the weights must be added accordingly to ensure that the tapes in the storage wheel group are in a vertically straightened state.

[0073] In some other embodiments of the present invention, the middle portion of the lifting beam 14 is provided with an enlarged portion 23 extending vertically, and a slider 15 assembled with the first vertical slide rail 13 is fixed to the enlarged portion 23 .

[0074] The beneficial effect of adopting the above technical solution is that the enlarged portion can increase the vertical dimension of the contact between the sliding block and the first vertical sliding rail, thereby ensuring the stability of the lifting beam.

[0075] In some other embodiments of the present invention, both ends of each upper driven wheel 7 and lower driven wheel 8 are provided with radially extending flanges, and the distance between the flanges at both ends of the same upper driven wheel 7 or lower driven wheel 8 is equal to the width of the first tape 4.

[0076] The beneficial effect of adopting the above technical solution is that the flange can allow the upper driven wheel and the lower driven wheel to just catch the tape, and the tape is not easy to slip off during the transmission process.

[0077] In some other embodiments of the present invention, the feed wheel group 3 includes a gantry, the gantry includes two columns 11 and a cross beam 12, the upper driven wheel 7 is connected to the cross beam 12, the top of the first vertical slide rail 13 is fixed to the cross beam 12, the top and bottom of the first vertical slide rail 13 are respectively provided with an upper limit block 16 and a lower limit block 17, the lower limit block 17 has a limit surface 22 for limiting the lowest limit position of the lifting beam, the limit surface 22 is a horizontal plane, and the number of the lower driven wheels 8 is not less than five.

[0078] The beneficial effects of adopting the above technical solution are: the gantry provides a fixed position for the entire feeding wheel group, raises the height of the upper driven wheel, and the limit surface of the lower limit block is located in the movement direction of the lifting beam, which can play a role in blocking the lifting beam. The number of lower driven wheels and upper driven wheels ensures that the storage wheel group can store a considerable length of tape, thereby extending the operating time.

[0079] In some other embodiments of the present invention, the discharging wheel set 1 includes an upper pressing wheel 5 and a lower pressing wheel 6 which are arranged up and down respectively, and the axes of the upper pressing wheel 5 and the lower pressing wheel 6 are parallel to each other.

[0080] The beneficial effect of adopting the above technical solution is that the upper pressing wheel and the lower pressing wheel respectively limit the front and back sides of a certain place of the tape to ensure that the tape is discharged from this place.

[0081] In other embodiments of the present invention, the driving wheel 10 in the feed wheel group 3 is connected to a rotating motor 18, and the rotating motor 18 is fixed with an angle seat 21. The bottom of the angle seat 21 and the bottom of the column are jointly fixed with a bottom plate 24, and the top height of the driving wheel 10 is flush with the top height of the lower pressure wheel 6.

[0082] The beneficial effects of adopting the above technical solution are: the rotating motor rotates the driving wheel, the angle seat provides assembly positions for various components, and the bottom plate provides a fixed platform for the entire mechanism. The heights of the discharge wheel group and the feed wheel group are consistent, ensuring that the tape will not be subjected to unidirectional tension on the storage wheel group due to the length of the tape on one side being too long.

[0083] In some other embodiments of the present invention, the angle seat 21 is further provided with a second vertical slide rail 20 and a linear cylinder 19 , and the linear cylinder 19 drives the lifting wheel 9 to perform linear reciprocating motion along the second vertical slide rail 20 .

[0084] The beneficial effect of adopting the above technical solution is that the second vertical slide rail plays a limiting and guiding role for the lifting and lowering of the lifting wheel.

[0085] In order to facilitate the structure representation, Fig.13 , Fig.14 , Fig.15 The bottom plate 24 is hidden in the figure. Fig.12 The dotted line in FIG. 4 is used to represent the trend of the first adhesive tape 4 . Fig.12 The height of the lifting beam 14 is also higher than Fig.11 middle.

[0086] Figure 2 The dotted lines also show the trends of the first adhesive tape 4, the second adhesive tape 56, and the reinforcing adhesive tape 57. The angle between the blades of the first cutter 25 and the second cutter 26 and the length direction of the first adhesive tape 4 is in the range of 15° to 45°. The lengths of the oblique ends of the first adhesive tape 4 and the second adhesive tape 56 cut by the first cutter 25 and the second cutter 26 are equal.

[0087] Preferably, the blade surface of the first cutter 25 faces away from the first adhesive tape 4 , and the blade surface of the second cutter 26 faces away from the second adhesive tape 56 .

[0088] The length of each section of reinforcing tape 57 on the lower pressing block 29 and after being cut by the third cutter 59 is fixed in unit time. The length of each section of reinforcing tape 57 is longer than the distance of the oblique end along the length direction of the first tape 4. The centroid of each section of reinforcing tape 57 after being attached coincides with the midpoint of the oblique end.
