Description

Technical Field

[0001] This utility model relates to the field of tape measurement technology, and in particular to a tape positioner with graduations for precise measurement. Background Technology

[0002] Adhesive tape is a common packaging and pasting product, typically composed of two parts: a substrate and an adhesive. The substrate can be various materials such as plastic film, paper, or fabric, providing the tape with basic strength and flexibility. The adhesive is coated on one side of the substrate, giving it stickiness and allowing it to adhere to various surfaces. There are many types of adhesive tape, including transparent tape, double-sided tape, electrical tape, and masking tape. Transparent tape, with its high transparency and strong adhesion, is widely used in daily life for packaging and sealing boxes; double-sided tape is adhesive on both sides and can be used to bond two objects; electrical tape has insulating properties and is mainly used for insulating and protecting electrical circuits; masking tape is often used in painting, decoration, and other fields for masking and positioning, effectively preventing paint or coating from staining unwanted areas.

[0003] A tape positioner is a convenient tool specifically designed to assist in the use of tape, playing a vital role in numerous scenarios. It primarily consists of a main frame, slots or clamping devices, and positioning components. Its working principle is based on the stable fixation and precise guidance of the tape. When the user needs to use the tape, they place the tape roll into the specific slot or clamping device of the positioner. The positioner will then fix the tape to a certain extent according to its size, ensuring that the tape does not wobble or shift during use. In this way, the user can more accurately control the direction and placement of the tape, thereby improving work efficiency and operational accuracy. In the packaging industry, tape positioners ensure that the tape is evenly applied to the sealing of cartons; in office settings, they facilitate document sealing and data organization; and in the field of handicrafts, they help to present various creative works beautifully, achieving efficient and convenient tape use.

[0004] However, some existing tape positioners use relatively fixed slots or clamping devices, which cannot flexibly adjust to accommodate changes in tape size when faced with tapes of different sizes. For some narrow tapes, the slots of the positioner are too wide, causing the tape to wobble and shift during use, making it difficult to achieve precise pasting. When encountering tape rolls with larger diameters, the clamping structure of the positioner cannot provide enough space to accommodate them, making it impossible to install and use the tape properly, thus failing to effectively fix tapes of different sizes. Therefore, to address these shortcomings, a tape positioner with graduated precision measurement is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tape positioner with graduations for precise measurement, which aims to improve the problem that some existing tape positioners cannot effectively fix tapes of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A graduated tape positioner includes a base and a tape body. A vertical plate is fixedly connected to the top of the base. A fixed shaft is fixedly connected to the front side of the vertical plate. A fixed block is fixedly connected inside the fixed shaft. A screw is threadedly connected inside the fixed block. A turntable is fixedly connected to the front side of the screw. A rotating disk is fixedly connected to the rear side of the screw. A sliding block is slidably connected inside the fixed shaft. Rotating rods are rotatably connected to both the left and right sides inside the sliding block. Arc-shaped plates are fixedly connected to the far sides of the two rotating rods. An adjustment component for adjusting tension is provided on the rear side of the base. A measuring component for measurement is provided on the front right end of the base.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes a fixed frame, the front side of which is fixedly connected to the rear side of the vertical plate. A sliding groove is provided inside the vertical plate. A sliding plate is slidably connected inside the fixed frame. A sliding rod is fixedly connected to the rear side of the sliding plate. A spring is sleeved on the outside of the sliding rod. A pull plate is fixedly connected to the rear side of the sliding rod. Multiple locking pins are fixedly connected to the front side of the sliding plate. A sliding shaft is slidably connected inside the vertical plate. A tensioning roller is fixedly connected to the outside of the sliding shaft.

[0010] As a further description of the above technical solution:

[0011] The measuring assembly includes a connecting shaft, which is fixedly connected to the outside of the vertical plate and to the inside of the vertical plate. A friction roller is rotatably connected to the outside of the connecting shaft. Multiple connecting rods are fixedly connected to the rear side of the friction roller. A scale is fixedly connected to the rear side of the multiple connecting rods. A counter is installed on the rear side of the vertical plate.

[0012] As a further description of the above technical solution:

[0013] The rotating disk is rotatably connected to the inside of the sliding block, and the outside of the arc plate is in contact with the inner wall of the tape body;

[0014] As a further description of the above technical solution:

[0015] The sliding rod is externally slidably connected to the inside of the fixed frame, and the front side of the pull plate is in contact with the rear side of the fixed frame;

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to the rear side of the sliding plate, and the other end of the spring is fixedly connected to the inside of the fixed frame;

[0018] As a further description of the above technical solution:

[0019] The outer side of the locking pin is slidably connected to the inside of the sliding shaft, and the outer side of the sliding shaft is slidably connected to the inside of the sliding groove;

[0020] As a further description of the above technical solution:

[0021] The connecting rod is slidably connected to the outside of the vertical plate, and the front side of the dial is rotatably connected to the rear side of the vertical plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the turntable on the front side of the rotating screw is rotated, and the screw is displaced axially under the restriction of the fixed block. The rear rotating disk rotates accordingly, causing the sliding block to slide within the fixed shaft. The rotating rod rotates with the displacement of the sliding block, thereby causing the arc plate to change position. This allows for adjustment according to the size of the tape, providing stable support for tapes of different specifications and ensuring that the tape will not shake or shift during use.

[0024] 2. In this invention, pulling the pull plate causes the sliding plate and sliding rod to shift, displacing the locking pin from the sliding shaft. This allows the tension roller, fixed to the sliding shaft, to slide up and down, adjusting its height to change the tape tension. Releasing the pull plate releases the spring, causing the locking pin to reset and lock, ensuring the tape maintains appropriate tension during use and preventing slack or wrinkles. For precise measurement, the measuring assembly includes a connecting shaft supporting a friction roller. The tape pulls the friction roller, which rotates. The connecting rod behind the friction roller transmits the rotation to a dial. A counter on the back of the vertical plate records the number of dial rotations. Combining the dial's circumference and the graduation value, the tape stretch length can be accurately calculated, achieving precise measurement. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a graduated tape positioning device, comprising a base 1 and a tape body 11. The base 1 serves as the basic support structure for the entire tape positioning device. The tape body 11 is the object to be positioned. A vertical plate 2 is fixedly connected to the top of the base 1, and a fixed shaft 3 is fixedly connected to the front side of the vertical plate 2. A fixed block 4 is fixedly connected inside the fixed shaft 3, and a screw 5 is threadedly connected inside the fixed block 4. When the screw 5 rotates, the fixed block 4 can stably restrict the movement direction of the screw 5, allowing it to only move axially. A turntable 6 is fixedly connected to the front side of the screw 5. When the turntable 6 rotates, the screw 5 rotates accordingly. Due to the threaded connection between the turntable 6 and the fixed block 4, the screw 5 will move linearly along the axial direction. A rotating disk 7 is fixedly connected to the rear side of the screw 5, and a sliding block 8 is slidably connected inside the fixed shaft 3. When the screw 5 rotates, the rotating disk 7 rotates synchronously and rotates inside the sliding block 8, thereby driving the sliding block 8 to slide axially within the fixed shaft 3, achieving position adjustment of the tape fixing device.

[0034] The rotating disk 7 is externally rotatably connected to the inside of the sliding block 8. When the rotating disk 7 rotates, it drives the sliding block 8 to slide along the fixed shaft 3. At the same time, the motion is transmitted to the arc plate 10 through the rotating rod 9, thereby fixing and adjusting the tape. Rotating rods 9 are rotatably connected to both the left and right sides inside the sliding block 8. Arc plates 10 are fixedly connected to the opposite sides of the two rotating rods 9. The outer side of the arc plate 10 is in contact with the inner wall of the tape body 11. When the sliding block 8 is displaced, the rotating rod 9 rotates around its connection point with the sliding block 8, thereby driving the arc plate 10 to move, thus fixing tapes of different sizes and ensuring the tape remains stable during use. An adjustment component for tension adjustment is provided on the rear side of the base 1, and a measuring component for measurement is provided on the front right end of the base 1.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The adjustment assembly includes a fixed frame 13, the front of which is fixedly connected to the rear of the vertical plate 2. The fixed frame 13 is used to install and protect the adjustment assembly. A groove 12 is provided inside the vertical plate 2, providing a precise sliding track for the sliding shaft 19. A sliding plate 14 is slidably connected inside the fixed frame 13, and a sliding rod 15 is fixedly connected to the rear of the sliding plate 14. When the pull plate 17 is pulled, the sliding plate 14 moves along with the sliding rod 15, thereby causing the locking pin 18 to disengage from or insert into the sliding shaft 19, thus locking and unlocking the height of the tension roller 20. The sliding rod 15 is slidably connected externally inside the fixed frame 13. The function of the sliding rod 15 is to transmit the pulling force of the pull plate 17 to the sliding plate 14, and simultaneously, under the action of the spring 16, to achieve automatic reset of the sliding plate 14. A spring 16 is sleeved on the outside of the sliding rod 15. One end of the spring 16 is fixedly connected to the rear side of the sliding plate 14, and the other end of the spring 16 is fixedly connected to the inside of the fixed frame 13. When the pull plate 17 is pulled to make the locking post 18 disengage from the sliding shaft 19, the spring 16 will be compressed and store elastic potential energy.

[0036] When the pull plate 17 is released, the spring 16 releases its elastic potential energy, pushing the sliding plate 14 and sliding rod 15 back to their original positions, causing the locking pins 18 to re-insert into the sliding shaft 19, thus locking the height of the tension roller 20. The pull plate 17 is fixedly connected to the rear side of the sliding rod 15, and the front side of the pull plate 17 contacts the rear side of the fixed frame 13. Multiple locking pins 18 are fixedly connected to the front side of the sliding plate 14, and these locking pins 18 cooperate with the interior of the sliding shaft 19 to lock and adjust the height of the tension roller 20. The sliding shaft 19 is slidably connected inside the vertical plate 2, and its exterior is slidably connected inside the slide groove 12. The sliding shaft 19 supports the tension roller 20 and, under the control of the adjusting component, allows for height adjustment of the tension roller 20. The locking pins 18 are slidably connected to the exterior of the sliding shaft 19, and the tension roller 20 is fixedly connected to the exterior of the sliding shaft 19. The main function of the tension roller 20 is to tension the tape, ensuring that the tape maintains appropriate tension during use.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The measuring assembly includes a connecting shaft 21, which is externally fixedly connected to the inside of a vertical plate 2. A friction roller 22 is rotatably connected to the outside of the connecting shaft 21. The connecting shaft 21 supports and mounts the friction roller 22. When the tape is stretched, the friction roller 22 rotates due to the friction between the tape and the friction roller 22. Multiple connecting rods 23 are fixedly connected to the rear side of the friction roller 22, and their external surfaces are slidably connected to the inside of the vertical plate 2. The connecting rods 23 transmit the rotation of the friction roller 22 to a scale 24. A scale 24 is fixedly connected to the rear side of the multiple connecting rods 23, and its front side is rotatably connected to the rear side of the vertical plate 2. A counter 25 is installed on the rear side of the vertical plate 2. The scale 24 is marked with graduations to visually display the stretched length of the tape. By detecting the number of rotations of the scale 24 by the counter 25 and combining this with the circumference and graduations of the scale 24, the stretched length of the tape can be accurately calculated.

[0038] Working Principle: When using this tape positioner, first select a tape body 11 of a certain size. Then, rotate the turntable 6 to drive the screw 5 to rotate. The screw 5 is displaced by the threaded connection between it and the fixing block 4. This causes the screw 5 and the turntable 7 to rotate inside the sliding block 8, displacing the sliding block 8. The displacement of the sliding block 8 causes the rotating rod 9 to rotate, adjusting the position of the arc plate 10. The arc plate 10 effectively fixes tape bodies 11 of different sizes. Then, remove one end of the tape body 11 and pass it over the bottom of the tension roller 20. When adjusting the height of the tension roller 20, pull the pull plate 17 to displace the sliding rod 15 and the sliding plate 14, which in turn displaces the locking pin 18. This allows the locking pin 18 to be moved from the sliding shaft 19. When the tape is removed from the inside, the spring 16 is compressed, and the tension roller 20 can be slid to allow the sliding shaft 19 to slide inside the groove 12, thereby adjusting the height of the tension roller 20. Then, the pull plate 17 can be released, and the spring 16's rebound allows the locking pin 18 to reset, allowing it to re-enter the sliding shaft 19 for fixation. When it is necessary to measure the tape length, one end of the tape can be passed through the bottom of the friction roller 22, and then the tape can be stretched. With the tape in a taut state, the friction between the tape and the friction roller 22 causes the friction roller 22 to rotate, which in turn drives the connecting rod 23 to rotate, which in turn drives the scale 24 to rotate. At this time, the counter 25 can be used to detect and record the number of rotations of the scale 24, thereby calculating the length of the tape stretched out. This completes the accurate measurement of the tape.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
