Description

Technical Field

[0001] This utility model relates to the field of tape cutting technology, and in particular to a foam tape cutting guide mechanism with adaptive width. Background Technology

[0002] Because foam tape is soft and easily stretched and deviates, it is necessary to ensure accurate material feeding and cutting stability during the cutting process. Therefore, a foam tape cutting guide mechanism is set up to accurately limit and guide the tape conveying path, ensuring the stability of the tape posture during cutting, achieving consistent size and neat edges, and improving processing quality and efficiency.

[0003] A search revealed Chinese patent publication number CN219563215U, which discloses a rubber strip cutting and guiding mechanism. This mechanism includes a guide plate with a limiting groove in its center. Adjustment grooves are located on both sides of the limiting groove. An adjusting guiding mechanism is installed within the limiting groove. A cutting block is mounted on the side of the guide plate, and a cutter is mounted on the side of the cutting block. The cutter has a limiting groove, and a limiting strip is connected within the limiting groove. A limiting plate is mounted on the side of the limiting strip, and a rack is connected to the side of the cutter. This invention places a pulley within the limiting groove and coordinates with a slider that limits sliding within the adjustment groove, achieving smooth movement of the adjusting plate. This increases the overall smoothness of the adjusting plate's movement and allows for flexible adjustment of the position of the adjusting guiding mechanism after installation. This enables flexible installation of the adjusting guiding mechanism and stable guiding and limiting of rubber strips with different hardness and diameters.

[0004] The aforementioned patent has the following shortcomings: due to the narrow width adjustment range and cumbersome adjustment operation of the device, when facing the processing needs of foam tapes of different widths, it is necessary to frequently disassemble and adjust the components and recalibrate the positioning, resulting in insufficient adaptability and making it difficult to respond quickly and efficiently to diverse production scenarios. This not only increases the operation time but also makes it difficult to stably guarantee the guiding accuracy of foam tapes of different widths, and it is not easy to fully meet the adaptation needs of multi-specification tapes in large-scale processing.

[0005] To address this, a foam tape cutting guide mechanism with adaptive width is proposed. Utility Model Content

[0007] The technical solution of this utility model embodiment is implemented as follows: an adaptive width foam tape cutting guide mechanism, including a top frame, and further including:

[0008] The guide wheel is bolted to the top of the top frame, and mounting seats are fixed on both sides of the top frame;

[0010] A positioning structure is set inside the connecting frame. The positioning structure includes a bidirectional lead screw rotatably connected to the bottom end of the connecting frame. A rocker arm is fixed to one side of the bidirectional lead screw. A moving block is threaded to the outer side of the bidirectional lead screw. A positioning plate that is slidably connected to a rotating roller is fixed to one side of the top of the moving block.

[0014] In some embodiments: the positioning plates are provided in two sets, and the two sets of positioning plates are symmetrically distributed on the vertical center line of the rotating roller.

[0015] In some embodiments: a sliding structure is formed between the moving block and the fixed roller, and the bidirectional lead screw extends to the outside of the connecting frame and is connected to the crank handle.

[0016] In some embodiments: the pressing structure includes a fixed frame fixed to one side of the top of the connecting frame, guide rails fixed on both sides inside the fixed frame, a lifting seat slidably connected to the guide rails inside the fixed frame, a pressure roller rotatably connected to one side of the lifting seat, a telescopic spring fixed to the top of the pressure roller, a pressing seat slidably connected to the guide rails fixed to the top of the telescopic spring, and an adjusting bolt threadedly connected to the fixed frame rotatably connected to the top of the pressing seat.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

"Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1 to 5 As shown, an adaptive width foam tape cutting guide mechanism includes a top frame 1, and further includes:

[0038] The retaining wheel 2 is bolted to the top of the top frame 1, and mounting bases 4 are fixed on both sides of the top frame 1.

[0039] The connecting frame 6 is rotatably connected to one side of the top frame 1. A fixed roller 10 is fixed at the bottom inside the connecting frame 6, and a rotating roller 3 is rotatably connected to the top inside the connecting frame 6. A front end plate 7 is rotatably connected to the bottom of the connecting frame 6 on the side away from the top frame 1.

[0040] Positioning structure 5 is located inside the connecting frame 6;

[0041] A pressing structure 8 for pressing the tape is provided on one side of the top of the connecting frame 6;

[0042] A flip structure 9 for adjusting the installation angle of the connecting frame 6 is provided at the bottom of the connecting frame 6.

[0043] In this embodiment, the top frame 1 is fixed at the designated processing position by means of the mounting base 4, and the angle between the connecting frame 6 and the top frame 1 is adjusted by the flipping structure 9. Then, one end of the foam tape is passed through the front end plate 7, the rotating roller 3 and the guide wheel 2 in sequence to extend into the equipment. The guide wheel 2 limits the top of the tape to ensure that the tape can be accurately connected to the subsequent cutting equipment.

[0044] like Figures 1 to 3As shown, the positioning structure 5 includes a bidirectional lead screw 502 rotatably connected to the bottom of the connecting frame 6. A rocker arm 504 is fixed to one side of the bidirectional lead screw 502. A moving block 503 is threadedly connected to the outer side of the bidirectional lead screw 502. A positioning plate 501 that is slidably connected to the rotating roller 3 is fixed to one side of the top of the moving block 503. A guide plate 505 is fixed to the side of the positioning plate 501 away from the top frame 1. External threads in opposite directions are provided on the outer side walls of both sides of the bidirectional lead screw 502. Internal threads that cooperate with the external threads are provided inside the moving block 503. Two sets of positioning plates 501 are provided. The two sets of positioning plates 501 are symmetrically distributed on the vertical center line of the rotating roller 3. A sliding structure is formed between the moving block 503 and the fixed roller 10. The bidirectional lead screw 502 extends to the outer side of the connecting frame 6 and is connected to the rocker arm 504.

[0045] In this embodiment, when it is necessary to adapt to foam tapes of different widths, the bidirectional lead screw 502 is rotated by turning the crank 504. Since the bidirectional lead screw 502 has external threads in opposite directions on both sides, and the internal threads and external threads inside the moving block 503 cooperate with each other, the rotation of the bidirectional lead screw 502 can drive the two sets of moving blocks 503 to move relative to or away from each other along the fixed roller 10. Then, the two sets of moving blocks 503 respectively drive the corresponding positioning plates 501 to move, so that the distance between the two sets of positioning plates 501 can be accurately adapted to foam tapes of different widths. At the same time, the guide plate 505 guides the incoming foam tape, guiding the tape smoothly into the limiting area between the two sets of positioning plates 501, ensuring that the tape is always transported in a centered state. To a certain extent, this avoids the tape from shifting or tipping over due to improper width adaptation, ensuring accurate positioning during the transport of tapes of different widths, and improving the adaptability of the mechanism to diverse processing needs.

[0046] Example 2:

[0047] An adaptive width foam tape cutting guide mechanism is provided in this embodiment, which is an improvement on embodiment 1, as follows: Figures 1 to 5 As shown, the pressing structure 8 includes a fixed frame 801 fixed to one side of the top of the connecting frame 6. Guide rails 805 are fixed on both sides inside the fixed frame 801. A lifting seat 802 is slidably connected to the guide rails 805 inside the fixed frame 801. A pressure roller 807 is rotatably connected to one side of the lifting seat 802. A telescopic spring 803 is fixed to the top of the pressure roller 807. A pressing seat 804 is slidably connected to the guide rails 805 fixed to the top of the telescopic spring 803. An adjusting bolt 806 is rotatably connected to the top of the pressing seat 804 and threadedly connected to the fixed frame 801. The lifting seat 802 forms a telescopic structure with the guide rails 805 through the telescopic spring 803. The pressure roller 807 and one of the sets of rotating rollers 3 are located on the same vertical center line.

[0048] In this embodiment, during the conveying of the foam tape, the pressing seat 804 moves up and down along the guide rail 805 by rotating the adjusting bolt 806. The pressing seat 804 then pushes the lifting seat 802 down through the telescopic spring 803, thereby adjusting the distance between the pressure roller 807 and the rotating roller 3 to accommodate foam tapes of different thicknesses. As the adjusting bolt 806 continues to rotate, the telescopic spring 803 contracts under force, providing continuous and uniform elastic pressure to the pressure roller 807. This allows the pressure roller 807 to closely adhere to the surface of the foam tape, preventing the tape from warping, wrinkling, or shifting due to its soft texture. This ensures the flatness of the tape conveying to a certain extent and works in conjunction with the centering and guiding function of the positioning structure 5 to further improve the accuracy of tape feeding and provide assurance for subsequent cutting quality.

[0049] like Figures 1 to 5 As shown, the flipping structure 9 includes a base frame 901 fixed to the bottom of the connecting frame 6. A flipping seat 903 is fixed to the bottom of the base frame 901. A flipping block 904 is rotatably connected inside the flipping seat 903. A connecting seat 902 is fixed to the bottom of the top frame 1. A rotating seat 907 is rotatably connected to the bottom of the connecting seat 902. A screw 905 is installed on one side of the rotating seat 907. A threaded sleeve 906 that is threadedly connected to the screw 905 is rotatably connected inside the flipping block 904. An external thread is provided on the outer wall of the screw 905, and an internal thread that cooperates with the external thread is provided inside the threaded sleeve 906.

[0050] In this embodiment, when the installation angle of the connecting frame 6 needs to be adjusted according to the production layout, the position of the screw sleeve 906 outside the screw 905 is adjusted by rotating the screw 905. This causes the screw sleeve 906 to move the base frame 901 via the flip block 904 and the flip seat 903. The base frame 901 then drives the connecting frame 6 to rotate around the connection point of the top frame 1, thereby achieving precise adjustment of the installation angle of the connecting frame 6. This ensures that the conveying structure on the connecting frame 6 can be precisely aligned with the cutting equipment and conveying path at the front and rear ends. To a certain extent, this ensures that the foam tape is always conveyed smoothly along the preset trajectory, avoiding tape offset or cutting errors due to angle deviation, and improving the adaptability and flexibility of the mechanism in different production scenarios.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
