Description

Technical Field

[0001] This utility model relates to the technical field of material belt conveying systems, specifically to a material belt traction and conveying device and a material belt joining machine. Background Technology

[0002] Tape splicing machines are mainly used in tape conveyor systems. When the working tape is about to run out, it can automatically connect to a spare tape to ensure the continuous operation of the production process. Tape splicing machines are widely applicable to the conveying of various materials such as plastic film, paper, cellulose film, and metal foil, and play an important role in many industries such as die-cutting, packaging, printing, and electronics.

[0003] The existing strip joining machine includes a frame with two strip joining mechanisms arranged laterally opposite each other. The working strip and the spare strip both pass through the space between the two strip joining mechanisms. The two strip joining mechanisms cooperate with each other to cut off the tail of the working strip and the head of the spare strip, and connect the working strip after the tail is cut off with the spare strip after the head is cut off, thereby realizing the joining of the strips.

[0004] In the operation of a strip joining machine, strip traction and feeding is an essential step. First, a spare strip needs to be placed in advance, and its end fixed to a strip head traction fixture. Then, the strip head traction fixture is passed through the space between two strip joining mechanisms. Finally, the strip head traction fixture is moved around to the top of one of the strip joining mechanisms and fixed to the machine frame. Currently, the method used for strip traction and feeding is as follows: one worker places the strip head traction fixture on the strip joining machine below the gap between the two strip joining mechanisms; another worker lifts the strip head traction fixture from above, moves it around to the top of one of the strip joining mechanisms, and finally fixes the strip head traction fixture to the machine frame.

[0005] This method requires close cooperation between two workers, and because the space between the two material belt joining mechanisms is relatively narrow, it is also difficult to pull the material head from above and guide the jig through the gap between the material belt joining mechanisms, which results in a waste of manpower and a reduction in work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a material belt traction and feeding device and a material belt joining machine to address the above problems and solve the problem of difficult material belt traction and feeding in the prior art.

[0007] To achieve the above objectives, this utility model discloses a material belt traction and conveying device. The material belt traction and conveying device includes a frame, on which two first mounting parts for mounting a material belt coupling mechanism are arranged laterally opposite each other. The frame is provided with a lifting mechanism, which includes two lifting arms that can automatically lift and lower. The two lifting arms are arranged laterally at a distance from each other. The upper end of the lifting arm is provided with a fixture placement part for placing a material head traction fixture. When the lifting arm is raised, it is used to lift the material head traction fixture to the gap between the two first mounting parts, or to make the material head traction fixture pass through the gap between the two first mounting parts. With the above structure, after the head of the spare material strip is fixed on the head traction fixture, the head traction fixture can be placed on the fixture placement part of one of the lifting arms. The lifting arm rises, causing the head traction fixture to rise from one side of the working material strip until it enters or passes through the gap between the two first mounting parts. Thus, only one worker needs to remove the head traction fixture from above the material strip joining mechanism and fix it to the frame, thereby completing the material strip traction and feeding operation. It is evident that this method facilitates the traction and feeding of the head of the spare material strip and the head of the spare material strip within the material strip joining machine. Only one worker is needed to fix the head of the spare material strip, saving labor, making operation more convenient, and greatly improving work efficiency.

[0008] Furthermore, a fixture fixing device for fixing the material head traction fixture is provided on the frame above the first mounting part. With the above structure, when the lifting mechanism raises the material head traction fixture, the worker can remove the material head traction fixture from above the material belt joining mechanism and fix it with the fixture fixing device to ensure that the spare material belt will not loosen during the joining process between the spare material belt and the working material belt.

[0009] Furthermore, the lifting mechanism includes two longitudinal lifting plates, with two lifting arms respectively mounted on the two longitudinal lifting plates. The two longitudinal lifting plates are laterally spaced, and both longitudinal lifting plates are mounted on the frame in a vertically sliding manner. The frame is equipped with a sliding drive device for driving the longitudinal lifting plates to slide vertically. With the above structure, the two longitudinal lifting plates provide a platform for mounting the lifting arms. The sliding drive device drives the longitudinal lifting plates to slide vertically, thereby raising and lowering the lifting arms. The increased lifting arms raise the support height for the fixture placement part, facilitating the retrieval of the material head traction fixture, and making it easier for the lifting arms to enter the gap between the two first mounting parts.

[0010] Furthermore, each of the two longitudinal lifting plates has two longitudinally spaced first notches on its adjacent side, and the first notches on the two longitudinal lifting plates correspond one-to-one to form two receiving spaces. Each receiving space is equipped with a sliding drive device consisting of a fixed mounting plate and a rodless cylinder. The fixed mounting plate is vertically positioned and fixedly connected to the frame. The rodless cylinder is mounted on the fixed mounting plate, with the rodless cylinder in one receiving space located on the first transverse side of the fixed mounting plate, and the rodless cylinder in the other receiving space located on the second transverse side of the fixed mounting plate. The slider assembly on the rodless cylinder is directly or through a connecting block located on its outer side and fixedly connected to the longitudinal lifting plate. With this structure, the two longitudinal lifting plates are joined more tightly, and the first notches on the longitudinal lifting plates form the receiving spaces for the sliding drive device. This structure allows the two lifting arms to be closer together, making the entire lifting mechanism more compact. To ensure better cooperation between the two strip joining mechanisms on the strip joining machine, the gap between the two first mounting parts needs to be relatively narrow. This compact design of the lifting mechanism allows the two lifting arms to smoothly enter the narrow space between the two first mounting parts.

[0011] Furthermore, linear bearings are installed at both longitudinal ends of the longitudinal lifting plate. Two longitudinally spaced outer fixing plates are provided on the frame, both vertically positioned. Vertical guide shafts are installed on both transverse sides of the two outer fixing plates. The two linear bearings on the longitudinal lifting plate located on the first transverse side are slidably engaged with the vertical guide shafts on the first transverse side of the two outer fixing plates, and the two linear bearings on the longitudinal lifting plate located on the second transverse side are also slidably engaged with the vertical guide shafts on the second transverse side of the two outer fixing plates. With this structure, the vertical sliding of the longitudinal lifting plate is achieved through the engagement between the vertical guide shafts and the linear bearings. By providing vertical guide shafts on both transverse sides of the outer fixing plates, the two longitudinal lifting plates can be brought closer together, which is beneficial for the compact design of the lifting mechanism.

[0012] Furthermore, two fixed mounting plates are located between two outer fixed plates, with a middle protective plate between the two fixed mounting plates. An outer protective plate is also provided between the outer fixed plates and their adjacent fixed mounting plates. Both the middle and outer protective plates are fixed to the frame. With this structure, the middle and outer protective plates together form an isolation structure, laterally separating the two lifting arms to prevent the spare material belt from sticking to the working material belt during the material belt traction and conveying process.

[0013] Furthermore, the lifting arm includes a longitudinal connecting plate and two vertical support rods. The two vertical support rods are longitudinally spaced apart, with their upper ends fixedly connected to the longitudinal connecting plate and their lower ends connected to the longitudinal lifting plate. The longitudinal connecting plate has two longitudinally spaced second notches at its transverse inner edge, corresponding vertically to the two first notches on the longitudinal lifting plate. With this structure, the vertical support rods connect the longitudinal connecting plate and the longitudinal lifting plate, making the longitudinal connecting plate higher than the longitudinal lifting plate, thereby increasing the support height of the lifting arm. The notches on the longitudinal connecting plate corresponding to those on the longitudinal lifting plate allow for the avoidance of the sliding drive device, which is beneficial for the compact design of the lifting mechanism.

[0014] Furthermore, L-shaped positioning blocks are installed at both ends of the longitudinal connecting plate. Each L-shaped fixing block includes a transverse wing plate and a vertical wing plate. The transverse wing plate is connected to the longitudinal connecting plate, and the free end of the vertical wing plate faces upwards. The vertical wing plate is spaced apart from the transverse outer surface of the longitudinal connecting plate. The transverse wing plate, vertical wing plate, and longitudinal connecting plate together form the fixture placement section. The vertical wing plate has threaded holes and is screwed with ball screws facing the longitudinal connecting plate. With this structure, the connecting plate, transverse wing plate, and vertical wing plate together form a fixture placement section for placing the material head traction fixture. The material head traction fixture can be placed from top to bottom. The ball screws limit the tightness of the material head traction fixture and ensure smooth placement and removal of the traction fixture.

[0015] Furthermore, the fixture fixing device includes two fixing blocks longitudinally spaced on the frame. Each fixing block has a limiting groove with an opening facing the lateral outward side of the frame. A movable limiting block, capable of lateral sliding, is installed on the frame at the opening side of the limiting groove. A force-applying spring is provided between the frame and the movable limiting block to allow the movable limiting block to slide towards the limiting groove. With this structure, during use, the material head traction fixture is placed in the limiting groove. The movable limiting block, under the action of the force-applying spring, presses the material head traction fixture firmly. The limiting groove faces the lateral outward side of the frame, ensuring that the material head traction fixture will not dislodge when subjected to a force acting laterally inward towards the frame.

[0016] This utility model also discloses a strip joining machine, which includes the strip traction and feeding device described above. A first mounting part on the frame is equipped with a strip joining mechanism that is driven by a power device and can move laterally. Two longitudinal strip unwinding rollers that are laterally spaced are mounted on the frame. The two longitudinal strip unwinding rollers are respectively located below the two strip joining mechanisms. A lifting mechanism is located between the two longitudinal strip unwinding rollers. A vertical blade is provided between the two strip joining mechanisms. When the two lifting arms are raised, they can respectively join the two joining mechanisms. The material head traction fixture on the placement section is lifted into the space between the vertical blade and the two material strip joining mechanisms. The material strip joining mechanism includes a material strip pressing device, an adhesive applicator, and a sliding cutting device that moves longitudinally driven by a power device. The sliding cutting device has a sliding cutting roller that can rotate around a vertical axis. The material strip pressing device is used to press the material strip onto the vertical blade, and the longitudinal movement of the sliding cutting device is used to make the sliding cutting roller engage with the upper edge of the vertical blade to cut the material strip. The adhesive applicator is used to attach the adhesive tape that has been placed on it to the cut end of the material strip. With the above structure, the material strip pressing device, adhesive applicator, and sliding cutting device on the two material strip joining mechanisms cooperate with the vertical blade to join the spare material strip and the working material strip together. The working material strip and the spare material strip are located on the lateral sides of the vertical blade, respectively. The two lifting arms can extend to the lateral sides of the vertical blade, respectively, to facilitate the traction and feeding of the spare material strip from the first or second lateral side of the vertical blade.

[0017] In summary, the beneficial effects of this utility model are as follows: This utility model provides a material belt traction and feeding device, which is applied to a material belt joining machine. It enables the material head traction fixture to be automatically lifted to the gap between the two first mounting parts, or to pass through the gap between the two first mounting parts. This makes it convenient for workers to take it from above the material belt joining mechanism and fix it, saving labor and improving work efficiency. Attached Figure Description

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] Figures 1 to 6 An embodiment of the material belt traction and feeding device of this utility model is disclosed.

[0031] Reference Figure 1 , Figure 3In one embodiment of this utility model, the material belt traction and feeding device includes a frame 1. Two first mounting portions 3 for mounting the material belt joining mechanism 2 are laterally oppositely arranged on the frame 1. A lifting mechanism 4 is provided on the frame 1, including two automatically lifting arms 5. The two lifting arms 5 are laterally spaced apart, and the upper end of each lifting arm 5 has a fixture placement portion 7 for placing a material head traction fixture 6. When the lifting arms 5 are raised, they are used to lift the material head traction fixture 6 to the gap between the two first mounting portions 3, or to allow the material head traction fixture 6 to pass through the gap between the two first mounting portions 3. The material belt joining mechanism 2... Figure 1 The specific structure of the strip joining mechanism 2, not shown in the diagram, can be found in [reference needed]. Figure 7 After the above improvements, once the head of the spare material belt is fixed on the head traction fixture 6, the head traction fixture 6 can be placed on the fixture placement part 7 of one of the lifting arms 5. The lifting arm 5 is raised so that the head traction fixture 6 rises from one side of the working material belt until the head traction fixture 6 enters or passes through the gap between the two first mounting parts 3. In this way, only one worker needs to remove the head traction fixture 6 from above the material belt joining mechanism 2 and fix it on the frame 1, thereby completing the material belt traction and feeding operation.

[0032] Reference Figure 1 In one embodiment of this utility model, a fixture fixing device 8 for fixing the material head traction fixture 6 is provided on the frame 1 above the first mounting part 3. When the lifting mechanism 4 lifts the material head traction fixture 6, the worker can remove the material head traction fixture 6 from above the material belt joining mechanism 2 and fix it with the fixture fixing device 8 to ensure that the spare material belt will not loosen during the process of joining the spare material belt with the working material belt by the material belt joining machine.

[0033] Reference Figure 2 , Figure 3 In one embodiment of this utility model, the lifting mechanism 4 includes two longitudinal lifting plates 9, and two lifting arms 5 are respectively mounted on the two longitudinal lifting plates 9. The two longitudinal lifting plates 9 are arranged laterally at intervals, and both longitudinal lifting plates 9 are mounted on the frame 1 in a manner that allows them to slide vertically. The frame 1 is provided with a sliding drive device 10 for driving the longitudinal lifting plates 9 to slide vertically. The two longitudinal lifting plates 9 provide a platform for mounting the lifting arms 5. The sliding drive device 10 drives the longitudinal lifting plates 9 to slide vertically, thereby raising and lowering the lifting arms 5. The lifting arms 5 increase the support height for the fixture placement part 7, making it easier to pick up the material head traction fixture 6, and also making it easier for the lifting arms 5 to enter the gap between the two first mounting parts 3.

[0034] Two longitudinally spaced first notches 11 are provided on the adjacent sides of the two longitudinal lifting plates 9. The first notches 11 on the two longitudinal lifting plates 9 correspond one-to-one to form two receiving spaces 12. A sliding drive device 10 consisting of a fixed mounting plate 13 and a rodless cylinder 14 is installed in each of the two receiving spaces 12. The fixed mounting plate 13 is vertically arranged and fixedly connected to the frame 1. The rodless cylinder 14 is installed on the fixed mounting plate 13. The rodless cylinder 14 in one receiving space 12 is located on the first transverse side of the fixed mounting plate 13, and the rodless cylinder 14 in the other receiving space 12 is located on the second transverse side of the fixed mounting plate 13. The slider assembly 15 on the rodless cylinder 14 is fixedly connected to the longitudinal lifting plate 9 directly or through the connecting block 16 located on its outer side. After the above improvements, the two longitudinal lifting plates 9 are more tightly joined. The first notch 11 on the longitudinal lifting plate 9 forms the receiving space 12 of the sliding drive device 10. This structure allows the two lifting arms 5 to get closer together, making the structure of the entire lifting mechanism 4 more compact. In order to make the two material belt joining mechanisms 2 on the material belt joining machine cooperate better, the gap between the two first mounting parts 3 needs to be set to be relatively narrow. This compact design of the lifting mechanism 4 allows the two lifting arms 5 to smoothly enter the narrow space between the two first mounting parts 3.

[0035] Reference Figure 3 , Figure 5 , Figure 6 In one embodiment of this utility model, linear bearings 17 are installed at both longitudinal ends of the longitudinal lifting plate 9. Two longitudinally spaced outer fixing plates 18 are provided on the frame 1. Both outer fixing plates 18 are vertically arranged, and vertical guide shafts 19 are installed on both transverse sides of the two outer fixing plates 18. The two linear bearings 17 on the longitudinal lifting plate 9 located on the first transverse side are slidably engaged with the vertical guide shafts 19 on the first transverse side of the two outer fixing plates 18. The two linear bearings 17 on the longitudinal lifting plate 9 located on the second transverse side are also slidably engaged with the vertical guide shafts 19 on the second transverse side of the two outer fixing plates 18. Through the above improvements, the vertical sliding of the longitudinal lifting plate 9 is achieved by utilizing the engagement between the vertical guide shafts 19 and the linear bearings 17. By providing vertical guide shafts 19 on both transverse sides of the outer fixing plates 18, the two longitudinal lifting plates 9 can be brought closer together, which is beneficial for the compact design of the lifting mechanism 4.

[0036] Reference Figure 3 , Figure 5 , Figure 6In one embodiment of this utility model, two fixed mounting plates 13 are located between two outer fixed plates 18, and an intermediate protective plate 20 is provided between the two fixed mounting plates 13. An outer protective plate 21 is provided between the outer fixed plates 18 and the adjacent fixed mounting plates 13. The intermediate protective plate 20 and the outer protective plate 21 are both fixed to the frame 1. The intermediate protective plate 20 and the outer protective plate 21 together form an isolation structure, which laterally separates the two lifting arms 5 to prevent the spare material belt from sticking to the working material belt during the material belt traction and conveying process.

[0037] The lifting arm 5 includes a longitudinal connecting plate 22 and two vertical support rods 23. The two vertical support rods 23 are longitudinally spaced apart. The upper ends of the two vertical support rods 23 are fixedly connected to the longitudinal connecting plate 22, and the lower ends of the two vertical support rods 23 are connected to the longitudinal lifting plate 9. The longitudinal connecting plate 22 has two longitudinally spaced second notches 24 at its transverse inner edge. The two second notches 24 on the longitudinal connecting plate 22 are vertically corresponding to the two first notches 11 on the longitudinal lifting plate 9. The vertical support rods 23 are used to connect the longitudinal connecting plate 22 and the longitudinal lifting plate 9, and to make the longitudinal connecting plate 22 higher than the longitudinal lifting plate 9, thereby increasing the support height of the lifting arm 5. The notches on the longitudinal connecting plate 22 corresponding to the longitudinal lifting plate 9 are used to avoid the sliding drive device 10, which is conducive to the compact design of the lifting mechanism 4.

[0038] Reference Figure 4 In one embodiment of this utility model, L-shaped positioning blocks 25 are installed at both ends of the longitudinal connecting plate 22. The L-shaped fixing block 28 includes a transverse wing plate 26 and a vertical wing plate 27. The transverse wing plate 26 is connected to the longitudinal connecting plate 22, and the free end of the vertical wing plate 27 faces upward. The vertical wing plate 27 is spaced apart from the transverse outer side of the longitudinal connecting plate 22. The transverse wing plate 26, the vertical wing plate 27, and the longitudinal connecting plate 22 together form the fixture placement part 7. The vertical wing plate 27 has a threaded hole and a ball screw 39 facing the longitudinal connecting plate 22 is screwed on it. The ball screw 39 is an existing structure and belongs to a type of set screw, consisting of a spring, a ball, and a threaded housing. The connecting plate 22, the transverse wing plate 26, and the vertical wing plate 27 together form a fixture placement part 7 for placing the material head traction fixture 6. The material head traction fixture 6 can be placed from top to bottom. The ball screw 39 tightens the material head traction fixture 6 to limit its position and ensures that the traction fixture 6 can be picked up and placed smoothly.

[0039] Figures 7 to 10 An embodiment of the material strip joining machine of this utility model is disclosed, wherein... Figures 7 to 9 The diagrams illustrate three working states of the material belt traction and feeding device on the material belt joining machine.

[0040] Reference Figure 9 , Figure 10In one embodiment of this utility model, the fixture fixing device 8 includes two fixing blocks 28 longitudinally spaced on the frame 1. Each fixing block 28 has a limiting groove 29 with an opening facing the lateral outer side of the frame 1. A movable limiting block 30, capable of lateral sliding, is installed on the frame 1 at the opening side of the limiting groove 29. A force-applying spring 31 is provided between the frame 1 and the movable limiting block 30 to allow the movable limiting block 30 to slide towards the limiting groove 29. In use, the material head traction fixture 6 is placed in the limiting groove 29. The movable limiting block 30, under the action of the force-applying spring 31, presses the material head traction fixture 6 tightly. The limiting groove 29 faces the lateral outer side of the frame 1, ensuring that the material head traction fixture 6 will not dislodge when subjected to a force acting laterally inward on the frame 1.

[0041] Reference Figure 7 , Figure 8 , Figure 9 In one embodiment of the strip joining machine, the strip joining machine includes the strip traction and feeding device described above. A first mounting part 3 on the frame 1 is equipped with a strip joining mechanism 2 that is driven by a power device and capable of lateral movement. Two longitudinal strip unwinding rollers 32, spaced laterally, are mounted on the frame 1. The two longitudinal strip unwinding rollers 32 are respectively located below the two strip joining mechanisms 2. A lifting mechanism 4 is located between the two longitudinal strip unwinding rollers 32. A vertical blade 33 is provided between the two strip joining mechanisms 2. When the two lifting arms 5 are raised, they can respectively pull the material heads on each self-gear placement part 7. The jig 6 is lifted into the space between the vertical blade 33 and the two strip joining mechanisms 2; the strip joining mechanism 2 includes a strip pressing device 34, an adhesive applicator 35, and a longitudinally moving sliding cutting device 36 driven by a power device. The sliding cutting device 36 has a sliding cutting roller 37 that can rotate about a vertical axis; the strip pressing device 34 is used to press the strip 38 onto the vertical blade 33, and the longitudinal movement of the sliding cutting device 36 is used to make the sliding cutting roller 37 engage with the upper edge of the vertical blade 33 to cut the strip 38; the adhesive applicator 35 is used to stick the adhesive tape that has been placed therein to the cut end of the strip 38. The material belt pressing device 34, adhesive applicator 35, and sliding cutting device 36 on the two material belt joining mechanism 2 cooperate with the vertical blade 33 to join the spare material belt and the working material belt together. The working material belt and the spare material belt are located on the horizontal sides of the vertical blade 33 respectively. The two lifting arms 5 can extend to the horizontal sides of the vertical blade 33 respectively, which facilitates the spare material belt to be pulled and fed from the first horizontal side or the second horizontal side of the vertical blade 33.

[0042] In this embodiment, the strip joining mechanism 2 includes a strip joining bracket that is laterally slidably mounted on the frame 1, and the strip joining bracket is driven to slide laterally by a cylinder or other power device mounted on the frame 1; the strip pressing device 34 includes a cylinder mounted on the strip joining bracket and a pressing plate driven by the cylinder; the adhesive applicator 35 includes a flipping frame hinged to the strip joining bracket, and an adhesive applicator pressing plate is provided on the flipping frame, and the flipping frame is driven to flip by a flipping cylinder mounted on the strip joining bracket to achieve the adhesive applicator action; the sliding cutting device 36 includes a sliding cutting bracket that is longitudinally slidably mounted on the strip joining bracket, and a sliding cutting roller 37 is rotatably mounted on the sliding cutting bracket, and the sliding cutting bracket is driven to slide longitudinally by a cylinder or other driving device mounted on the strip joining bracket.

[0043] Figure 7 , Figure 8 , Figure 9 The diagram illustrates three operating states of the strip traction and feeding device. In the diagram, the strip 38 on the left longitudinal strip unwinding roller 32 is the working strip, and the strip 38 on the right longitudinal strip unwinding roller 32 is the spare strip. In these three operating states, the lifting mechanism 4 on the right side operates to traction and feed the spare strip. Of course, in other operating states, the strip 38 on the right longitudinal strip unwinding roller 32 can also be set as the working strip. In this case, the strip 38 on the left longitudinal strip unwinding roller 32 is the spare strip, and the lifting mechanism 4 on the left side needs to operate to traction and feed the spare strip.

[0044] The following is based on Figure 7 , Figure 8 , Figure 9 Taking the working state shown as an example, let's describe the working mode of the material belt traction and feeding device: First, refer to... Figure 7 After fixing the head of the spare conveyor belt to the head traction fixture 6, the head traction fixture 6 is placed in the fixture placement part 7 located at the upper end of the lifting arm 5, at which point the lifting arm 5 is in a lowered state; then, refer to Figure 8 The lifting arm 5 is raised upwards, causing the material head traction fixture 6 to rise to the gap between the two material belt joining mechanisms 2, or causing the material head traction fixture 6 to extend upwards through the gap between the two material belt joining mechanisms 2; finally, refer to Figure 9 Lift the material head traction fixture 6 from above the material belt joining mechanism 2 located on the right side, so that the material head traction fixture 6 is away from the fixture placement part 7. Wrap the material head traction fixture 6 around the upper part of the material belt joining mechanism 2 and pull it outward to fix the material head traction fixture 6 on the fixture fixing device 8. This completes the material belt traction and feeding of the spare material belt.

[0045] Next, let's take... Figure 7 , Figure 8 , Figure 9 For example, let's describe how the strip splicing machine works: (Refer to...) Figure 9 After the spare material strip is pulled and fed, the material strip joining mechanism 2 on the right side of the figure moves laterally to the left to approach the vertical blade 33. The material strip pressing device 34 on the right material strip joining mechanism 2 presses the spare material strip against the right side of the vertical blade 33. The sliding cutting device 36 on the right material strip joining mechanism 2 moves longitudinally toward or away from the paper surface. The lower edge of the sliding cutting roller 37 on the right material strip joining mechanism 2 fits against the upper edge of the vertical blade 33 to cut the spare material strip. The adhesive applicator 35 on the right material strip joining mechanism 2 applies the adhesive tape that has been placed therein to the spare material strip after the material head has been cut off. The tape extends beyond the reserved section of the spare tape, and the tape pressing device 34 on the left tape joining mechanism 2 presses the working tape onto the left side of the vertical blade 33. The sliding cutting device 36 on the left tape joining mechanism 2 moves longitudinally toward or away from the paper surface. The lower edge of the sliding cutting roller 37 on the left tape joining mechanism 2 fits against the upper edge of the vertical blade 33 to cut the working tape. The adhesive applicator 35 on the left tape joining mechanism 2 works to bond the working tape after the material tail is cut to the portion of the tape that extends beyond the reserved section of the spare tape, thereby achieving the joining of the working tape and the spare tape.
