Description

Technical Field

[0001] This utility model relates to the field of tape cutting technology, and in particular to a tape cutting device. Background Technology

[0002] For ease of transport and loading / unloading, existing adhesive tapes are mostly supplied in roll form. Before use, they need to be cut to a preset length and fixed onto a suction unit; subsequently, the suction unit moves the cut tapes at intervals to facilitate subsequent processes such as application. However, in existing tape-cutting devices, each suction unit is equipped with a drive unit to drive its movement, resulting in a complex structure for the tape-cutting device. Utility Model Content

[0003] Therefore, it is necessary to provide a rubber cutting device that improves upon the aforementioned shortcomings, addressing the issue of the complex structure of existing rubber cutting devices.

[0004] This application provides a rubber cutting device, comprising:

[0005] A glue-absorbing assembly, comprising at least two glue-absorbing elements spaced apart;

[0006] The adhesive cutting assembly includes a cutter that is movably disposed between two adjacent adhesive suction components;

[0007] A variable pitch assembly includes a mounting component, a connector, a fixing component, and at least two spaced-apart movable components. The movable components are movably mounted on the mounting component. The connector has a first sliding groove. One of two adjacent movable components is movably mounted in the first sliding groove, and the other is fixedly connected to the connector. One end of the fixing component is fixedly connected to the mounting component, and the other end is connected to one of the movable components at its end. Adsorption components are respectively connected to the movable components.

[0008] A drive assembly is driven to connect to the moving part at the end furthest from the fixed part.

[0009] By incorporating a pitch-changing component and movably connecting adjacent moving parts via connectors, when the drive component moves the moving part away from the fixed part forward, the connectors sequentially drive the remaining moving parts, thereby achieving the spacing distribution of the adsorption components connected to each moving part. This ultimately allows for adjustment of the spacing between the cut tape pieces. In other words, by movably connecting adjacent moving parts via connectors, linkage pitch-changing between the moving parts is achieved. This eliminates the need for a separate drive component for each moving part, simplifying the tape-cutting device structure and reducing production costs.

[0010] In some embodiments, the adhesive suction assembly includes a first adhesive suction member, a second adhesive suction member, a third adhesive suction member, and a fourth adhesive suction member arranged at intervals;

The fixing member includes a second sliding groove and a third sliding groove spaced apart. The first moving member is movably disposed in the second sliding groove. The second moving member is movably connected to the first moving member through the connecting member. The third moving member is movably disposed in the third sliding groove. The fourth moving member is movably connected to the third moving member through the connecting member. The first adhesive-absorbing member, the second adhesive-absorbing member, the third adhesive-absorbing member, and the fourth adhesive-absorbing member are respectively connected to the first moving member, the second moving member, the third moving member, and the fourth moving member.

[0012] The drive assembly includes a first drive member and a second drive member that are respectively drivenly connected to the second moving member and the fourth moving member.

[0036] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0037] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0042] To better understand the embodiments of this application, the following is combined with... Figures 1 to 9 The embodiments of this application will be described in detail.

[0043] like Figures 1 to 9As shown, this application provides a glue-cutting device 1, including a glue-suction assembly 11, a glue-cutting assembly 12, a pitch-changing assembly 13, and a drive assembly 14. The glue-suction assembly 11 includes at least two spaced-apart glue-suction members; the glue-cutting assembly 12 includes a cutter 121 movably disposed between two adjacent glue-suction members; the pitch-changing assembly 13 includes a mounting member 131, a connecting member 132, a fixing member 133, and at least two spaced-apart moving members. The moving members are movably disposed on the mounting member 131. The connecting member 132 is provided with a first groove 1321. One of two adjacent moving members is movably disposed on the first groove 1321, and the other is fixedly connected to the connecting member 132. One end of the fixing member 133 is fixedly connected to the mounting member 131, and the other end is connected to the moving member at the end. The suction members are respectively connected to the moving members; the drive assembly 14 is drivenly connected to the moving member at the end away from the fixing member 133.

[0044] The adhesive suction assembly 11 is used to adsorb and fix the tape 2. The adhesive suction assembly 11 includes at least two spaced adhesive suction elements to adsorb and fix the cut sections of tape 2. Specifically, the adhesive suction elements are connected to the negative pressure element. The negative pressure delivered by the negative pressure element is used to adsorb and fix the tape 2. Compared with other clamping devices such as grippers, the negative pressure adsorption element can reduce mechanical damage to the tape 2 and can also adsorb and fix the tape 2 flatly in the adsorption element, preventing the tape 2 from wrinkling and ensuring the subsequent adhesive application quality of the tape 2.

[0045] The tape cutting assembly 12 includes a cutter 121 disposed between two adjacent adhesive suction members. The cutter 121 can cut the tape and adsorb it onto the suction members on both sides. Furthermore, the cutter 121 is movable, allowing it to move closer to the tape 2 to cut it. Specifically, the movable arrangement of the cutter 121 can be achieved through a guide rail slider mechanism or a lead screw mechanism; this embodiment does not limit the specific implementation.

[0046] The pitch-adjusting assembly 13 is a component for adjusting the distance between the cut tapes 2. The pitch-adjusting assembly 13 includes a mounting member 131 and at least two spaced-apart movable members. The movable members are movably mounted on the mounting member 131, thereby adjusting the distance between the movable members by moving them relative to the mounting member 131. The movable connection between the movable members and the mounting member 131 can be achieved through either a guide rail slider mechanism or a lead screw mechanism; this embodiment does not limit this. Simultaneously, since each adsorption member is connected to a movable member, when the movable members move relative to the mounting member 131 to adjust their respective distances, they can also move to adjust the distance between each movable member, thereby achieving the adjustment of the distance between the cut tapes 2. It should be noted that the adsorption members and movable members can be directly connected or indirectly connected through an intermediate member; this embodiment does not limit this.

[0047] In addition, the pitch-changing assembly 13 also includes a fixing member 133 and a connecting member 132. The connecting member 132 is provided with a first sliding groove 1321. One of two adjacent moving members is movably disposed in the first sliding groove 1321, while the other is fixedly connected to the connecting member 132, allowing the two adjacent moving members to move relative to each other and adjust their spacing. One end of the fixing member 133 is fixedly connected to the mounting member 131, and the other end is connected to an end moving member. The end moving member is located at both ends and is connected to other moving members on only one side, while the other side is free. Because adjacent moving members are connected via the connecting member, connecting the other end of the fixing member 133 to the end moving member ensures a defined relative positional relationship between the moving member and the mounting member 131, thereby determining the relative positional relationship between each moving member and the mounting member 131. It should be noted that the fixing member 131 and the movable member at the end can be fixedly connected, so that the movable member at the end is fixed on the mounting member 131; the fixing member 131 and the movable member at the end can also be movably connected, so that the movable member at the end can also move a certain distance relative to the mounting member 131, thereby adjusting the position of each movable member on the mounting member 131.

[0048] Specifically, when the free end moving part (i.e. the moving part furthest from the fixed part 133 along the moving path) moves relative to the mounting part 131, the moving part moves relative to the adjacent moving part through the first slide groove 1321. When the moving part abuts against the end of the first slide groove 1321, it will pull the adjacent moving part to move as well (at this time, the relative distance between the two moving parts is fixed). Similarly, the adjacent moving part will transmit power sequentially until it reaches the moving part at the other end. At this time, since the moving part at the other end is connected to the mounting part 131 through the fixed part 133, each moving part eventually stops moving and is set on the mounting part 131 at a preset interval, thereby realizing the adjustment of the distance between each moving part.

[0049] The drive assembly 14 is driven to move the movable part at the end away from the fixed part 133, thereby driving the movable part at the end away from the fixed part 133 to move, which in turn drives the adjacent movable parts to move in sequence, and finally realizes the adjustment of the spacing of the movable parts.

[0050] By setting up the pitch-changing component 13 and connecting two adjacent moving parts through the connector 132, when the drive component 14 drives the moving part away from the fixed part to move forward, the connector can sequentially drive the remaining moving parts to move, thereby achieving the spacing distribution of the adsorption components connected to each moving part, and ultimately adjusting the spacing between the tapes 2 after cutting. That is, by movably connecting two adjacent moving parts through the connector 132, the linkage pitch-changing between the moving parts can be achieved, eliminating the need for a separate drive component 14 for each moving part, simplifying the structure of the tape cutting device 1 and reducing production costs.

[0051] like Figures 1 to 9 As shown, in some embodiments, the adhesive suction assembly 11 includes a first adhesive suction member 111, a second adhesive suction member 112, a third adhesive suction member 113, and a fourth adhesive suction member 114 spaced apart; the variable pitch assembly 13 includes a first moving member 134, a second moving member 135, a third moving member 136, and a fourth moving member 137; the fixing member 133 includes a second sliding groove 1331 and a third sliding groove 1332 spaced apart; the first moving member 134 is movably disposed in the second sliding groove 1331; and the second moving member 135 is movable to the first moving member 134 via a connecting member 132. The third moving part 136 is movably disposed in the third slide groove 1332, and the fourth moving part 137 is movably connected to the third moving part 136 through the connector 132. The first adhesive suction part 111, the second adhesive suction part 112, the third adhesive suction part 113, and the fourth adhesive suction part 114 are respectively disposed on the first moving part 134, the second moving part 135, the third moving part 136, and the fourth moving part 137. The drive assembly 14 includes a first drive part 141 and a second drive part 142 that are respectively drivenly connected to the second moving part 135 and the fourth moving part 137.

[0052] The adhesive suction assembly 11 includes a first adhesive suction member 111, a second adhesive suction member 112, a third adhesive suction member 113, and a fourth adhesive suction member 114 arranged at intervals. Meanwhile, the variable distance assembly 13 includes a first moving member 134, a second moving member 135, a third moving member 136, and a fourth moving member 137. The spacing between the four adhesive suction members is adjusted by adjusting the spacing between the four moving members. Finally, the four cut adhesive tapes 2 are arranged at intervals in the adhesive cutting device 1 to facilitate the subsequent adhesive application process.

[0053] The second movable member 135 is movably connected to the first movable member 134 via a connector 132. That is, one of the first movable member 134 and the second movable member 135 is movably disposed in the first slide groove 1321, and the other is fixedly connected to the connector 132. Similarly, the fourth movable member 137 is movably connected to the third movable member 136 via a connector 132, meaning that one of the third movable member 136 and the fourth movable member 137 is movably disposed in the first slide groove 1321, and the other is fixedly connected to the connector 132.

[0054] The fixing member 133 includes a second slide groove 1331 and a third slide groove 1332 spaced apart. The first moving member 134 and the third moving member 136 are movably disposed within the second slide groove 1331 and the third slide groove 1332, respectively. This allows for the formation of independently adjustable linked moving members on both sides of the fixing member 133, accelerating the adjustment of the spacing between the moving members and simplifying the equipment while improving production efficiency. Furthermore, the arrangement of the second slide groove 1331 and the third slide groove 1332 allows for adjustment of the spacing between the first moving member 134 and the third moving member 136, ultimately achieving spacing adjustment for all four moving members. It should be noted that, depending on actual needs, the glue-cutting device 1 can also be equipped with three or more sets of linked adjustable moving member groups, and each linked adjustable moving member group can contain three or more moving members. This embodiment does not impose any limitations on this.

[0055] Specifically, such as Figures 6 to 7 As shown, when the distance is increased, the first driving member 141 and the second driving member 142 respectively drive the second moving member 135 and the fourth moving member 137 to move away from each other relative to the mounting member 131. At the same time, the second moving member 135 moves within the first sliding groove 1321 and moves away from the first moving member 134, while the fourth moving member 137 moves within the first sliding groove 1321 and moves away from the third moving member 136. This achieves distance adjustment for the second moving member 135 and the first moving member 134, and distance adjustment for the fourth moving member 137 and the third moving member 136, respectively. Subsequently, the second moving member 135 drives the first moving member 134 to move within the second sliding groove 1331 via the connecting member 132, while the fourth moving member 137 drives the third moving member 136 to move within the third sliding groove 1332 via the connecting member 132, thereby achieving distance adjustment for the first moving member 134 and the third moving member 136. Finally, the first moving part 134, the second moving part 135, the third moving part 136 and the fourth moving part 137 are set in the mounting part 131 at preset intervals.

[0056] like Figures 5 to 7As shown, in some embodiments, the pitch assembly 13 further includes a guide 138 spaced apart from the mounting member 131. The two ends of the guide 138 are fixedly connected to the mounting member 131, and the first moving member 134, the second moving member 135, the third moving member 136 and the fourth moving member 137 are movably inserted through the guide 138.

[0057] The guide 138 is spaced apart on one side of the mounting member 131 and its two ends are fixedly connected to the mounting member 131. In this way, by setting the guide 138, the first moving member 134, the second moving member 135, the third moving member 136 and the fourth moving member 137 can be guided to move relative to the mounting member 131, ensuring the smooth movement of the first moving member 134, the second moving member 135, the third moving member 136 and the fourth moving member 137.

[0058] like Figure 1 and 3 As shown, in some embodiments, the rubber cutting device 1 further includes a frame 15, and the mounting component 131 is movably disposed on the frame 15.

[0059] By movably mounting the mounting component 131 to the frame 15, the position of the adhesive suction assembly 11 and the pitch change assembly 13 in the adhesive cutting device 1 can be adjusted by moving the mounting component 131.

[0060] Specifically, such as Figure 1 The frame 15 is provided with a horizontally extending guide rail 151 on one side, and the mounting component 131 is movably mounted on the guide rail 151. In this way, when the mounting component 131 moves relative to the guide rail 191, the horizontal position of the variable pitch component 13 and the glue suction component 11 can be adjusted, thereby improving the applicability of the glue cutting device 1.

[0061] like Figure 1 , 3 As shown in Figures 8 and 9, in some embodiments, the glue cutting device 1 further includes a glue dispensing assembly 16 and a glue pressing assembly 17. The glue dispensing assembly 16 includes a glue dispensing member 161 rotatably disposed on one side of the glue cutting assembly 12 and a glue pulling gripper 162 movably disposed on the other side of the glue cutting assembly 12; the glue pressing assembly 17 is movably disposed on one side of the glue suction assembly 11.

[0062] The tape unwinding assembly 16 is used to unwind the tape 2 from the roll material to facilitate the segmentation and bonding of the tape 2. The tape unwinding assembly 16 includes a tape unwinding member 161 rotatably disposed on one side of the tape cutting assembly 12. The roll material is disposed in the tape unwinding member 161, and the tape 2 in the roll state is conveyed out by the rotation of the tape unwinding member 161. In addition, the unwinding assembly 16 also includes a tape pulling jaw 162 movably disposed on the other side of the tape cutting assembly 12. The tape pulling jaw 162 clamps the free end of the tape 2 in the roll material, and the movement of the tape pulling jaw 162 conveys the tape 2 from the tape unwinding member 161 to one side of the tape cutting assembly 12 to facilitate the cutting and segmentation of the tape 2.

[0063] The pressure-pressing component 17 is movably disposed on one side of the adhesive suction component 11, and is used to gradually approach the adhesive suction component 11, so that the adhesive tape 2 between the two can be flatly adsorbed and fixed in the adsorption component without wrinkling or displacement. Specifically, the movable setting of the pressure-pressing component 17 can be achieved by a guide rail slider mechanism or a lead screw mechanism, and this application embodiment does not limit this.

[0064] like Figures 1 to 4 As shown in Figures 8 and 9, in some embodiments, the glue dispensing assembly 16 further includes a glue guide 163 and a fixing gripper 164. The glue guide 163 is disposed between the glue dispensing assembly 161 and the glue cutting assembly 12, and a guide groove 1631 is provided on the surface of the glue guide 163; the fixing gripper 164 is disposed between the glue guide 163 and the glue cutting assembly 12.

[0065] An adhesive guide 163 is positioned between the adhesive dispensing component 161 and the adhesive cutting component 12, and a guide groove 1631 is provided on the surface of the adhesive guide 163. In this way, under the traction of the adhesive gripper 162, the tape 2 conveyed from the roll material located at the adhesive dispensing component 161 will pass through the guide 163 and, guided by the guide groove 1631, be conveyed along a preset path between the pressing component 17 and the suction component 11. This ensures that the tape 2 can be accurately conveyed in the adhesive cutting device 1, and then accurately adsorbed and fixed in the suction component. That is, the design of the guide groove 1631 ensures that the tape 2 remains stable during movement, without shifting or wrinkling, thereby improving the cutting accuracy of the tape 2.

[0066] The fixing jaw 164 is disposed between the adhesive feeding component 163 and the adhesive cutting component 12, and is used to clamp and fix the adhesive tape 2. On the one hand, after the adhesive feeding jaw 162 conveys the adhesive tape 2 to the predetermined position, the fixing jaw 163 can fix the adhesive tape 2, so that the adhesive tape 2 located between the adhesive feeding jaw 162 and the fixing jaw 163 is in a fixed state, ensuring the stability of the adhesive tape 2 during the cutting process and improving the cutting accuracy; on the other hand, by fixing the adhesive tape 2 with the fixing jaw 163, it can be ensured that the free end of the adhesive tape 2 is still located between the adhesive feeding jaw 162 and the fixing jaw 163 after the cutting is completed, which facilitates the subsequent clamping of the free end of the adhesive tape 2 by the adhesive feeding jaw 162 and ensures the continuity of the adhesive cutting process.

[0067] like Figures 1 to 3 As shown, in some embodiments, the glue cutting device 1 further includes a buffer assembly 18, which includes a first feed roller 181, a buffer roller 182, and a second feed roller 183 arranged sequentially and spaced apart between the glue dispensing member 161 and the fixed gripper 164. The buffer roller 182 is movable to adjust the path length between the first feed roller 181, the buffer roller 182, and the second feed roller 183.

[0068] The buffer assembly 18 includes a first pass roller 181, a buffer roller 182, and a second pass roller 183, which are sequentially spaced between the glue dispensing component 161 and the fixed gripper 164. That is, the tape 2 conveyed from the glue dispensing component 161 passes through the first pass roller 181, the buffer roller 182, and the second pass roller 183 in sequence, and is finally conveyed to one side of the glue cutting assembly 12.

[0069] The buffer roller 182 is movable to adjust the path length between the first guide roller 181, the buffer roller 182, and the second guide roller 183, thereby adjusting the length of the conveyor belt 2 in the buffer assembly 18. Specifically, the first guide roller 181, the buffer roller 182, and the second guide roller 183 are arranged in a triangle. When the buffer roller 182 moves, the perimeter of the triangle can be changed, thereby changing the length of the conveyor belt 2's transport path and adjusting the length of the conveyor belt 2 buffered by the buffer assembly 18.

[0070] By setting the buffer component 18, on the one hand, the tension of the tape 2 can be adjusted by the buffer roller 182 to ensure that the tape 2 maintains a stable tension during the feeding and cutting process, reducing the loosening or breakage of the tape 2 caused by uneven tension and improving the processing quality of the tape; on the other hand, the buffer component 18 provides a buffer area so that the tape 2 can maintain a certain reserve during the feeding and cutting process, so that when the feeding part 161 is feeding, the cutting device 1 still has tape 2 to supply, ensuring the continuity of the cutting process.

[0071] like Figure 1As shown, in some embodiments, an anti-stick layer 1821 is provided on the surface of the buffer roller 182. During the conveying of the tape 2, since the buffer roller 182 is in contact with the side of the tape 2 coated with adhesive, the anti-stick layer 1821 on the surface of the buffer roller 182 can prevent the tape 2 from sticking to the buffer roller 182 and affecting the tape cutting effect, and can also prevent the buffer roller 182 from damaging the adhesive of the tape 2, thus ensuring the adhesion of the tape 2.

[0072] like Figure 1 As shown, in some embodiments, the buffer assembly 18 includes a glue-passing component 184 rotatably sleeved on the first pass roller 181, the buffer roller 182, and the second pass roller 183; or the first pass roller 181, the buffer roller 182, and the second pass roller 183 are rotatably arranged about their own axes.

[0073] In some embodiments, the buffer assembly 18 includes a gluing component 184, which is rotatably sleeved on the first gluing roller 181, the buffer roller 182, and the second gluing roller 183. In this way, the gluing component 184 can rotate as the tape 2 moves, reducing the friction between the tape 2 and the buffer assembly 18 and ensuring the production quality of the tape 2.

[0074] In other embodiments, the first guide roller 181, the buffer roller 182, and the second guide roller 183 can be rotatably arranged around their own axes. In this way, when the tape 2 moves in the buffer assembly 18, the first guide roller 181, the buffer roller 182, and the second guide roller 183 can rotate accordingly, thereby reducing the friction between the tape and the buffer assembly 18 and ensuring the production quality of the tape 2.

[0075] Specifically, such as Figures 1 to 9 As shown, during feeding, the roll of adhesive tape 2 is placed in the adhesive placement component 161. The adhesive tape 2 passes sequentially through the first guide roller 181, the buffer roller 182, the second guide roller 183, the guide component 163, and the fixing gripper 164 before reaching one side of the adhesive cutting component 12.

[0076] When cutting the tape, the tape-pulling claw 161 clamps the free end of the fixed tape 2 and pulls the tape 2 to move between the tape-pressing component 17 and the tape-suction component 11; when the tape-pulling claw 161 reaches the preset position, the fixed claw 164 clamps the fixed tape 2, and then the tape-pressing component 17, the tape-suction component 11, and the cutter 121 gradually approach the tape 2 to cut the tape and adsorb and fix it in the adsorption component.

[0077] Subsequently, the first driving member 141 and the second driving member 142 respectively drive the second moving member 135 and the fourth moving member 137 to move away from each other relative to the mounting member 131, so that the second moving member 135 and the fourth moving member 137 move within the first slide groove 1321 respectively, moving away from the first moving member 134 and the third moving member 136 respectively; then, the second moving member 135 and the fourth moving member 137 respectively drive the first moving member 134 and the third connecting member 136 to move within the second slide groove 1331 and the third slide groove 1332 respectively through the connecting member 132, so as to realize the distance adjustment of the first moving member 134 and the third moving member 136. This makes the tape 2 in the first adsorption member 111, the second adsorption member 112, the third adsorption member 113 and the fourth adsorption member 114 distributed at preset intervals.

[0078] Finally, the adhesive-pulling jaw 162 approaches the fixed jaw 164 and clamps the free end of the fixed tape 2. The fixed jaw 164 releases the tape 2, allowing the adhesive-pulling jaw 161 to pull the tape back into the space between the pressing assembly 17 and the suction assembly 11 for the next tape-cutting process.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
