Description

Technical Field

[0001] This utility model relates to the field of line marking auxiliary construction technology, and in particular to a tape cutting and resetting device and a tape marking machine using the device. Background Technology

[0002] Before roads, factories, and workshops are officially put into use, different types of adhesive tape need to be laid on the ground to serve as indicators, reminders, or warnings, depending on the specific needs. To reduce the labor intensity of the personnel laying the tape, professional line marking machines are currently mainly used for line marking.

[0003] However, most commonly used tape marking machines lack cutting capabilities. After the marking lines are drawn, operators still need to bend over and manually cut the tape, increasing their workload. Furthermore, the cut edges may have sharp edges, affecting the appearance. Therefore, on November 12, 2024, the applicant filed a patent application with application number "CN 202422749317.7" entitled "A Tape Cutting Tool and a Tape Marking Machine Using the Tool," which enables rapid and automated cutting of tape.

[0004] After the aforementioned marking machine cuts the tape, workers need to bend down or squat down at the next designated position to reset the tape before it can be properly pasted on the ground. This not only increases the workload of the workers but also affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a tape cutting and resetting device and a tape marking machine using the device, which not only enables rapid tape cutting but also automatically resets the tape, avoiding the need for workers to bend over to reset the tape and improving work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tape cutting and resetting device includes a tape roll that can be rotated to release the tape, and an auxiliary wheel for tensioning the tape, a cutting blade for cutting the tape, and a front pressure wheel for pressing the tape onto the ground are arranged sequentially along the tape's movement path. The auxiliary wheel has the following characteristics: a lifting posture that moves upward and pulls the tape, causing the cutting tool to cut the tape, and a lowering posture that resets the tape and presses the cut end of the tape onto the ground.

[0007] Preferably, the auxiliary wheel is connected to a control rope via a traction device, and a first handbrake is provided at the end of the control rope. The first handbrake controls the switching of the auxiliary wheel between the raised and reset postures by tightening / releasing.

[0008] Preferably, the auxiliary wheel also has a semi-raised posture, which moves upward to lift off the ground.

[0009] Preferably, the auxiliary wheel is connected to a control rope via a traction device, and a second handbrake device is provided at the end of the control rope. The second handbrake device controls the switching of the auxiliary wheel between a half-raised posture, a raised posture, and a reset posture by first tightening / second tightening / releasing.

[0010] Preferably, the traction device includes a first link and a second link, with a third link hinged to the ends of the first link and the second link, the third link being connected to an auxiliary wheel, and the first link or the second link being connected to a control rope.

[0011] Preferably, the traction device includes a fourth link connected to the control rope, the fourth link having a bent portion connected to the auxiliary wheel.

[0012] Preferably, the traction device includes a guide portion connected to the control rope and a connecting block connected to the auxiliary wheel, and a guide rod is provided between the guide portion and the connecting block; The traction device also includes a support part, on which an opening is provided for the guide rod to move.

[0013] Preferably, the second handbrake device includes a cover plate and a handle located at the end of the control cable; The cover plate is provided with a first movable groove that guides the handle from the loose position to the first tightening position and a second movable groove that guides the handle from the first tightening position to the second tightening position.

[0014] Preferably, the second handbrake device further includes a limiting groove for positioning the primary braking position.

[0015] Preferably, this application also discloses a tape marking machine, including a main support frame, on which the aforementioned tape cutting and resetting device is provided.

[0016] The beneficial effects of this utility model are as follows: 1. The tape can be quickly cut and reset by moving the auxiliary wheels, which greatly improves the operator's efficiency and user experience.

[0017] 2. To prevent the auxiliary wheel from participating in tape pressing during normal tape application, which could lead to air bubbles and wrinkles on the tape surface (because the auxiliary wheel is merely placed on the ground and not in close contact with it), the auxiliary wheel is designed to be in a semi-raised position, detached from the ground. In this position, the auxiliary wheel does not participate in tape pressing; instead, the front pressure wheel performs the tape pressing (because under the operator's downward pressure, the front pressure wheel is firmly pressed against the ground, making close contact with it), thus improving the tape's adhesion.

[0018] 3. The use of a wire control rope and traction device ensures that the auxiliary wheel moves up and resets smoothly, allowing it to cut the tape or press it to the ground, thus enhancing the reliability of operation.

[0019] 4. This application designs three different traction devices, which can be selected according to specific needs, thus improving the adaptability of the equipment.

[0020] 5. The auxiliary wheel can be freely switched between three working postures through the second handbrake device, which simplifies the operator's work and improves the reliability of the equipment. Attached Figure Description

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Example 1 like Figure 1 As shown in the figure, the tape marking machine described in this embodiment includes a main support 1. The upper end of the main support 1 is provided with a handle 5 for easy gripping. The lower part of the main support 1 is connected to a secondary support 2. The end of the secondary support is provided with a rear pressure roller 4. In order to prevent the marking from being skewed, a guide pin (not shown in the figure) can also be provided at the front end of the main support 1. The above components and their connection relationships are all existing conventional technologies, and will not be described in detail in this embodiment.

[0025] To improve the performance of the marking machine and optimize its user experience, a tape cutting and resetting device is installed on the main support 1. Figure 2 and Figure 3 As shown, the tape cutting and resetting device includes a tape roll 6 and a rotatable support plate mounted on the main support 1. The tape roll 6 is secured to the support plate. After one end of the tape on the tape roll 6 is pasted to the ground, as the marking machine moves forward, the tape roll 6 drives the support plate to rotate, thereby releasing the tape. Along the tape's movement path are sequentially arranged an auxiliary wheel 10 for tensioning the tape, a cutting blade 11 for cutting the tape, and a front pressure wheel 3 for pressing the tape onto the ground. The front pressure wheel 3 and the cutting blade 11 are both mounted at the bottom of the main support 1. When the operator pushes the tape marking machine forward using the handle 5, they press down on the main support 1 to increase the pressure of the front pressure wheel 3 on the tape, ensuring it is firmly pasted to the ground. The outer edge of the cutting blade 11 is higher than the ground and will not contact the tape during normal pasting.

[0026] like Figure 4 and Figure 5 As shown, the auxiliary wheel 10 has two operating postures: a lifting posture where it moves upward and pulls the tape 61, causing the cutting blade 11 to cut the tape 61; and a resetting posture where it moves downward and presses the cut end of the tape 61 onto the ground. When the tape marking machine completes marking the current path and needs to cut the tape 61, the auxiliary wheel 10 is moved upward, causing the tape 61 to contact the cutting blade 11 and cut the tape 61. Afterward, when the tape marking machine moves to the next marking path, the auxiliary wheel 10 is moved downward to contact the ground, pressing the end of the tape 61 onto the ground. Then, the tape marking machine is pushed forward so that the front pressure wheel 3 presses the tape, thus achieving normal marking operation. This reduces the bending and pasting process for the operator and optimizes the operating experience.

[0027] The cutting blade 11 used in this embodiment is from the applicant's previous patent application entitled "A Tape Cutting Device and Tape Applying Tool with Anti-Drift Function" with application number "CN202322750218.6". After cutting the tape with this blade, the cut tape can be adhered and fixed to a certain extent. During the process of moving the tape marking machine to the next application position, the tape drift can be effectively prevented. When the tape needs to be applied at the designated position, the auxiliary wheel 10 moves down to contact the ground, forcibly releasing the tape from the blade and applying the tape to the ground.

[0028] The relevant structures and working principles of the aforementioned patents will not be described in detail in this embodiment.

[0029] like Figure 1 As shown, the auxiliary wheel 10 is connected to the control rope 7 via the traction device 9. A first handbrake 12 is located at the end of the control rope 7. The first handbrake 12 controls the switching of the auxiliary wheel 10 between the raised and reset positions by tightening / releasing it. The first handbrake 12 is positioned side-by-side with the handle 5 for easy operation. A fixing part 8 is also provided on the main support 1, through which the control rope 7 passes, providing some support and guidance. The control rope 7 can be made of steel wire rope, which is not easily worn and has a long service life. The traction device 9 is installed on the main support 1, making the movement of the auxiliary wheel 10 smooth and controllable.

[0030] When the first handbrake 12 is engaged, it drives the auxiliary wheel 10 upward through the control rope 7 and the traction device 9, entering a raised position and cutting the tape 61, thus ending the current tape-applying process. When the first handbrake 12 is released, the auxiliary wheel 10 moves downward under its own weight, entering a reset position and driving the control rope 7 and the traction device 9 to reset (so that it can re-enter the raised position), while pressing the tape 61 onto the ground, thus starting a new tape-applying process. To ensure that the force generated when the auxiliary wheel 10 moves downward and contacts the ground is sufficient to press the tape 61 onto the ground, the weight of the auxiliary wheel 10 can be increased by adding a counterweight to the auxiliary wheel 10, or a reset spring can be installed between the traction device 9 and the main support 1 to further increase its reset force. The above structures are all existing conventional technologies and will not be described in detail in this embodiment.

[0031] In this embodiment, to meet different customer needs, three different traction devices are provided, which will be described one by one below: like Figure 3 As shown, the first type of traction device 9 includes a first connecting rod 91 and a second connecting rod 92. One end of the first connecting rod 91 and the second connecting rod 92 are both hinged to the main support 1, and the other end of the first connecting rod 91 and the second connecting rod 92 are both hinged to the third connecting rod 93. The third connecting rod 93 is connected to the auxiliary wheel 10, and the first connecting rod 91 is connected to the control rope 7.

[0032] like Figure 7 As shown, the second type of traction device 9 includes a fourth link 94 connected to the control rope 7, and the fourth link 94 has a bent portion 95 connected to the auxiliary wheel 10.

[0033] like Figure 8 and Figure 9 As shown, the third type of traction device 9 includes a guide part 96 connected to the control rope 7 and a connecting block 99 connected to the auxiliary wheel 10. A guide rod 97 is provided between the guide part 96 and the connecting block 99. The traction device 9 also includes a support part 98, which is mounted on the main support 1. The support part 98 has an opening for the guide rod 97 to move, which plays a certain guiding role in the movement of the guide rod 97.

[0034] In the aforementioned first traction device, the lengths of the first link 91 and the second link 92 can be precisely designed. When the auxiliary wheel 10 moves down to reset, the tape stuck to the cutting tool 11 can be precisely pulled off and the end of the tape can be pressed onto the ground. (The first traction device can ensure that the end of the tape is pressed onto the ground, avoiding pressing the middle of the tape onto the ground, which could cause the end of the tape to flip over and stick to the subsequent front pressure wheel 3.)

[0035] The second and third traction devices cannot achieve precise control; that is, they cannot ensure that the end of the tape is precisely pressed onto the ground when the auxiliary wheel 10 moves down to reset.

[0036] Example 2 The tape marking machine described in Example 1 has the following problems that the applicant discovered during use: When the auxiliary wheel 10 is in its reset position, it will naturally contact the ground. On the moving path of the tape 61, the auxiliary wheel 10 is located in front of the front pressure wheel 3, and will press the tape 61 onto the ground in advance. However, because the auxiliary wheel 10 is in natural contact with the ground, and the operator cannot increase the contact force between the auxiliary wheel 10 and the ground by pressing down on the main support 1 (due to the presence of the traction device 9, when pressing down on the main support 1, the force can only be transmitted to the front pressure wheel 3, not to the auxiliary wheel 10), the pressing of the tape 61 by the auxiliary wheel 10 is not thorough, resulting in gaps, air bubbles, wrinkles, etc., which the subsequent front pressure wheel 3 cannot resolve.

[0037] Therefore, in this embodiment, the auxiliary wheel 10 is also designed in a semi-raised position. In this state, although the auxiliary wheel 10 moves upward and leaves the ground, it has not yet made the tape 61 contact the cutting tool 11. Figure 6As shown, in this posture, when the tape marking machine is working, the auxiliary wheel 10 no longer presses the tape 61 onto the ground in advance, but directly presses it onto the ground through the front pressure wheel 3, which solves the aforementioned problems such as gaps, air bubbles, and wrinkles.

[0038] In order to enable the auxiliary wheel 10 to switch between three postures: half-raised posture, raised posture, and reset posture, this embodiment designs a corresponding second handbrake device.

[0039] like Figure 10 As shown, the auxiliary wheel 10 is connected to the control rope 7 via the traction device 9. The end of the control rope 7 is equipped with a second handbrake device. The second handbrake device controls the switching of the auxiliary wheel 10 between the half-raised posture, the raised posture, and the reset posture by tightening once / tightening twice / releasing.

[0040] like Figure 11 — Figure 13 As shown, the second handbrake device includes a cover plate 14 and a movable rod 131 located at the end of the control rope 7. A handle 13 is provided on the movable rod 131, and the handle 13 can rotate around the movable rod 131. The cover plate 14 is fixed to the main support 1 by bolts.

[0041] The cover plate 14 is provided with a first movable groove 142 that guides the handle 13 from the loose position to the first tightening position, and a second movable groove 143 that guides the handle 13 from the first tightening position to the second tightening position. The second movable groove 143 is located between the cover plate 14 and the main support 1. The cover plate 14 is also provided with a limiting groove 141 for positioning the first tightening position.

[0042] When the handle 13 is at its lowest position, it is in the released state. At this time, the auxiliary wheel 10 moves down under its own weight and is in the reset position. When the tape 61 is cut and the tape marking machine is moved to the starting point of the new marking, the end of the tape 61 is pressed to the ground in this state. As the handle 13 is lifted, it moves up along the first movable groove 142 to the limit slot 141, which is a first tightening. At this time, the auxiliary wheel 10 moves up under the tension of the control rope 7 and is in a half-lifted position. This state is the normal working state of the tape marking machine. In order to ensure that the handle 13 will not move up and down accidentally in this state, causing the auxiliary wheel 10 to shake, the handle 13 can be rotated 90° and locked in the limit slot 141. It cannot move down due to the obstruction of the limit slot 141. Moreover, in this embodiment, for a better user experience, a magnet 15 is also provided in the limit slot 141. Since the handle 13 is made of iron, the magnetic attraction further prevents the handle 13 from shaking during normal operation of the equipment. Based on the aforementioned position, once the current marking work is completed and the tape 61 needs to be cut, continue lifting the handle 13 upwards, moving it along the second movable groove 143 to the secondary clamping position. During this process, the auxiliary wheel 10 continues to move upwards under the tension of the control rope 7, adjusting from a half-lifted posture to a fully lifted posture, ultimately bringing the tape 61 into contact with the cutting blade 11, and cutting the tape 61. The aforementioned cutting process occurs instantaneously. After cutting, release the handle 13. Under its own weight and the attraction of the aforementioned magnet 15, the handle 13 immediately falls back to the primary clamping position and remains in that position. This falling back process will not cause the auxiliary wheel 10 to pull the tape off the cutting blade 11. Then, move the tape marking machine to the next marking position and then lower the handle 13 back to its lowest position.
