[0001] This utility model relates to a tape cutting machine, and more particularly to a feed inlet structure for a tape cutting machine. Background Technology

[0002] A tape cutter is used to cut tape and is commonly used in the production of bags, decorations, and other products. A tape cutter generally includes: a feeding shaft for holding the tape roll, a feed inlet structure for feeding the tape, a traction structure for moving the tape, and a cutting structure for cutting the tape. Existing feed inlet structures typically include: a base plate for mounting the tape cutter, multiple guide rods for feeding the tape, and a pressure plate whose position can be adjusted relative to the base plate. After passing through the guide rods, the tape passes between the base plate and the pressure plate. Adjusting the position of the pressure plate flattens the tape, facilitating its traction and cutting. Utility Model Content

[0003] This application provides a feed inlet structure for a tape cutter, which solves the problem that existing feed inlet structures lack an alarm reminder function after the tape roll has finished unloading.

[0004] This application provides a feed inlet structure for a tape cutter, including: The base plate has multiple parallel strip grooves along its longitudinal direction; The mounting part is fixedly connected to the base plate on the first side of the transverse direction of the multiple strip grooves; The sensor is mounted on the mounting part; A pressure plate is hinged to the mounting portion about a longitudinal axis; an extended pressure foot is provided for each strip groove near the second side edge of the strip groove, the pressure foot including a first extension portion overlapping the pressure plate and a first bent portion for pressing material; an elastic element is provided between the pressure plate and the mounting portion, the elastic element being used to keep the pressure plate in the following state: triggering the sensor and the pressure foot passing through the corresponding strip groove; A horizontal first guide rod, with its axis running longitudinally, is fixedly connected to the mounting part on the first side of the pressure plate; Multiple limiting blocks are fixedly connected to the first guide rod, and their fixed positions can be adjusted longitudinally. A horizontal second guide rod, with its axis running longitudinally, is fixedly connected to the mounting part on the first side of the first guide rod.

[0005] In some embodiments, the hinge point of the pressure plate at the mounting portion coincides with the axis of the first guide rod, and the plurality of limiting blocks are circular.

[0006] In some embodiments, one of the plurality of limiting blocks is adjustable and fixed in position around the axis of the first guide rod; the limiting block also has a third extension portion extending toward the pressure plate, the third extension portion being used to keep the pressure plate in the following state: a gap is left between the pressure foot and the base plate.

[0007] In some embodiments, the pressure plate includes: two mounting blocks for hinged to the mounting portion and a plate body for connecting the pressure foot; the plate body is fixedly connected to the two mounting blocks and can also be adjusted in position along the orientation of the extension portion.

[0008] In some embodiments, both ends of the first guide rod protrude from the mounting portion, and the pressure plate is hinged to the two protruding ends of the first guide rod.

[0009] In some embodiments, the outer wall of the limiting block has a threaded hole, and a first bolt is threaded into the threaded hole.

[0010] In summary, this application discloses a feed inlet structure for a tape cutter, comprising a base plate, a mounting portion, a sensor, a pressure plate, a first guide rod, multiple limiting blocks, and a second guide rod. An elastic element is used to maintain the pressure plate in the following state: the sensor is triggered and the pressure foot passes through the corresponding slot. This state can only be achieved when no tape passes through the slot; conversely, if tape passes through the slot, the pressure foot presses against the tape and cannot pass through the corresponding slot, thus preventing the sensor from being triggered. The sensor can be used to control the tape cutter; upon triggering, the tape cutter's operation is paused.

[0011] Its beneficial effects include: simple structure, smoother belt feed from the inlet, and an alarm function that alerts the system when the belt is used up. Attached Figure Description

[0016] Please see Figure 1 , Figure 2 and Figure 3 A feed inlet structure for a tape cutter includes a base plate 1, a mounting part 2, a sensor 3, a pressure plate 4, a first guide rod 5, multiple limit blocks 6, and a second guide rod 7.

[0017] The base plate 1 has multiple strip grooves 1a. For ease of explanation of orientation later, in top view, the orientation of these strip grooves 1a is set to be horizontal, and correspondingly, these strip grooves 1a are arranged in a row along the longitudinal direction.

[0018] Mounting part 2 is fixedly connected to base plate 1. More specifically, there can be two mounting parts 2, which are fixedly connected to both sides of base plate 1 in the longitudinal direction. In the transverse direction, the mounting parts 2 and the strip grooves 1a on base plate 1 are staggered, on the first side of these strip grooves 1a.

[0019] Sensor 3 is mounted on mounting part 2. More specifically, capacitive sensor 3 may be used.

[0020] The pressure plate 4 is hinged to the mounting part 2, and the axis around which the hinge is located is longitudinal. More specifically, the pressure plate 4 may have downwardly bent second bends on both sides of its longitudinal direction, and these two second bends are used to hinge with the mounting part 2. That is to say, the pressure plate 4 triggers the sensor 3 by swinging.

[0021] The pressure plate 4 is provided with multiple pressure feet 4a1 on the second side edge near the strip groove 1a. These pressure feet 4a1 extend toward the strip groove 1a and correspond one-to-one with the multiple strip grooves 1a.

[0022] Please see Figure 1 and Figure 4 The presser foot 4a1 includes a first extension portion 4a1a and a first bent portion 4a1b. The first end of the first extension portion 4a1a is connected to the second side edge of the pressure plate 4, and the first extension portion 4a1a also coincides with the pressure plate 4, that is, the included angle between the first extension portion 4a1a and the pressure plate 4 is 180 degrees. The first bent portion 4a1b is connected to the second end of the first extension portion 4a1a, and the included angle between the two is an obtuse angle. The first bent portion 4a1b is used to press down the belt passing through the feed port.

[0023] An elastic element is provided between the pressure plate 4 and the mounting part 2. More specifically, the elastic element can be a torsion spring, which is provided at the hinge position between the pressure plate 4 and the mounting part 2; or it can be a tension spring, with its two ends connected to the pressure plate 4 and the mounting part 2 respectively.

[0024] The elastic element is used to maintain the pressure plate 4 in the following state: the sensor 3 is triggered and the pressure foot 4a1 passes through the corresponding slot 1a. That is, this state can only be achieved when no tape passes through the slot 1a. Conversely, if tape passes through the slot 1a, the pressure foot 4a1 will press on the tape and cannot pass through the slot 1a, thus not triggering the sensor 3. The sensor 3 can be used to control the tape cutter; after triggering, the tape cutter's operation is paused.

[0025] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the pressure plate 4 includes two mounting blocks 4b and a plate body 4a. The two mounting blocks 4b are hinged to the mounting part 2, and the plate body 4a is used for connecting the pressure foot 4a1. The plate body 4a is also fixedly connected to the two mounting blocks 4b. Compared with the above-mentioned method of hinged connection of two integral first bent portions 4a1b on the pressure plate 4, the design of hinged connection of two mounting blocks 4b makes the assembly between the pressure plate 4 and the mounting part 2 more convenient. The plate body 4a can also be adjusted and fixed in position along the orientation of the first extension portion 4a1a. More specifically, the plate body 4a has a waist-shaped groove 4a2a at the position corresponding to the two mounting blocks 4b, and bolts are used to pass through the waist-shaped grooves 4a2a and threadedly connected to the mounting blocks 4b.

[0026] The thickness of the belt passing through the feed inlet will vary. By swinging the pressure plate 4, it can be found that there is only one position where the first bent part 4a1b of the pressure foot 4a1 is parallel to the base plate 1. By adjusting the fixed position of the plate 4a on the two mounting blocks 4b, belts of different thicknesses can be adapted to the surface.

[0027] Please see Figure 1 and Figure 2 The first guide rod 5 is horizontal and its axis is longitudinal, and it is fixedly connected to the mounting part 2. That is, both ends of the first guide rod 5 are fixedly connected to the two mounting parts 2 respectively. In the transverse direction, the first guide rod 5 and the pressure plate 4 are staggered, and the first guide rod 5 is on the first side of the pressure plate 4.

[0028] Multiple limiting blocks 6 are fixedly connected to the first guide rod 5, and these limiting blocks 6 can also be adjusted and fixed in the longitudinal direction.

[0029] Please see Figure 1 In some embodiments, the outer wall of the limiting block 6 has a threaded hole, and a first bolt 6a is threaded into the threaded hole. That is, tightening the first bolt 6a so that the first bolt 6a abuts against the outer wall of the first guide rod 5, the limiting block 6 and the first guide rod 5 are relatively fixed.

[0030] When multiple belts pass through the feed inlet, multiple limiting blocks 6 are used to limit the belt movement. That is, the belt passes between two adjacent limiting blocks 6. Adjusting the fixed position of the limiting blocks 6 can accommodate belts of different widths. Of course, the pressure plate 4 needs to be able to swing within a certain range, and the relative positions of the pressure plate 4 and the first guide rod 5 need to be properly set so that these limiting blocks 6 do not affect the pressure plate 4.

[0031] Please see Figure 1 and Figure 4 In some embodiments, the hinge point of the pressure plate 4 at the mounting portion 2 coincides with the axis of the first guide rod 5. More specifically, the pressure plate 4 may have a second extension portion 4a2 on both sides of the first side edge in the longitudinal direction, and the aforementioned second bent portion / mounting block 4b is connected to the second extension portion 4a2. The plurality of limiting blocks 6 are circular.

[0032] It can easily meet the requirement that the limit block 6 does not affect the swing of the pressure plate 4 within a certain range.

[0033] Please see Figure 1 In some embodiments, both ends of the first guide rod 5 protrude from the mounting part 2, and the pressure plate 4 is hinged to the two protruding ends of the first guide rod 5.

[0034] It can easily meet the requirement that the hinge point of the pressure plate 4 in the mounting part 2 coincides with the axis of the first guide rod 5.

[0035] Please see Figure 3In some embodiments, among the multiple limiting blocks 6, one limiting block 6 can be adjusted and fixed in position around the axis of the first guide rod 5. More specifically, the hole on the limiting block 6 through which the first guide rod 5 passes can be a complete circular hole. Of course, multiple limiting blocks 6 can be configured such that multiple limiting blocks 6 can be adjusted and fixed in position around the axis of the first guide rod 5, and one limiting block 6 with a suitable position can be selected. The limiting block 6 also has a third extension portion 6b extending towards the pressure plate 4, which is used to keep the pressure plate 4 in the following state: a gap is left between the pressure foot 4a1 and the base plate 1.

[0036] The limiting block 6 is adjusted and fixed around the axis of the first guide rod 5, allowing the third extension portion 6b to move closer to or further away from the pressure plate 4. When moving away, the third extension portion 6b does not affect the swing of the pressure plate 4. When moving closer, the third extension portion 6b can abut against the pressure plate 4, preventing the pressure plate 4 from swinging downwards and maintaining a gap between the pressure foot 4a1 and the base plate 1. With this gap between the pressure foot 4a1 and the base plate 1, initially, the end of the belt can easily pass between the pressure foot 4a1 and the base plate 1. Adjusting the limiting block 6 releases the abutment of the third extension portion 6b against the pressure plate 4, and under the action of the elastic element, the pressure foot 4a1 of the pressure plate 4 presses down on the belt.

[0037] Please see Figure 1 The second guide rod 7, referencing the first guide rod 5, is horizontal with its axis running longitudinally, and is fixedly connected to the mounting part 2 on the first side of the first guide rod 5. The belt, guided by the first guide rod 5 and the second guide rod 7, then enters between the pressure foot 4a1 and the base plate 1.
