Description

Technical Field

[0001] This invention relates to a handle grip tape wrapping device. Background Technology

[0002] Most ball sports rackets have a fixed handle area. At the factory, a layer of grip tape is wrapped around the handle. This grip tape, made of rubber, has excellent elasticity and sweat-absorbing properties to improve grip comfort, anti-slip performance, and shock absorption. The quality of this grip tape wrapping directly affects the athlete's feel and performance. Grip tape that is too thick, too thin, or too messy will all negatively impact performance. Currently, most grip tape wrapping is done manually, making it difficult to control the wrapping angle and tension. The wrapping quality relies entirely on the operator's experience. During the wrapping process, the handle is prone to wobbling and unstable rotation, further exacerbating problems such as wrapping misalignment and uneven overlap. This not only significantly reduces the quality of the grip tape wrapping but also leads to low work efficiency and high workload for the operator. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of handle shaking during manual handle wrapping, which leads to misalignment and uneven overlap of the wrapping material. This invention proposes a handle wrapping device that uses a rotating body inside the cavity to support the handle and a limiting connection hole on the cover plate to constrain the handle's rotation. This device can significantly improve the regularity and forming accuracy of the wrapping material, as well as increase work efficiency.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a handle adhesive wrapping device, comprising a housing and a cover plate, wherein the housing is provided with a cavity, and an opening is provided on one side of the cavity; the cover plate is disposed on the housing, and a limiting connection hole is provided on the cover plate; the handle passes through the limiting connection hole, and the limiting connection hole and the handle are in clearance fit; when the handle rotates, the outer wall of the handle contacts the inner wall of the limiting connection hole to generate friction; the friction is used to stabilize the adhesive wrapping tension; a rotating body for supporting the handle is rotatably connected inside the cavity; a strip-shaped through groove communicating with the cavity is provided on the side wall of the housing, and the adhesive extends into the cavity through the strip-shaped through groove.

[0005] Preferably, a pressure plate is movably connected to the housing, and the pressure plate can move into the cavity to press the starting end or the tail end of the hand glue tightly against the outer wall of the handle.

[0006] Preferably, the housing has a through hole, and a spring sheet is provided in the through hole. The pressure plate is disposed on the spring sheet. The pressure plate moves into the cavity by means of the deformation of the spring sheet to press the hand glue, and the pressure plate is reset by means of the elastic force of the spring sheet.

[0007] Preferably, there are two through holes, which are respectively located at the upper and lower ends of the housing, and a pressure plate is installed in each of the two through holes.

[0008] Preferably, there is a first single-sided gap of 0.2mm to 1mm between the inner wall of the through hole and the pressure plate.

[0009] Preferably, the cover plate is detachably mounted on the housing.

[0010] Preferably, there is a second single-sided gap of 0.1mm to 0.5mm between the inner wall of the limiting connection hole and the handle.

[0011] Preferably, the rotating body includes a rotating shaft and a support plate, the support plate is disposed on the rotating shaft, and the rotating shaft is rotatably connected to the cavity through a bearing.

[0012] Preferably, the outer wall of the housing is provided with scale markings.

[0013] Preferably, the cavity is provided with a column for mounting the adhesive tape roll.

[0014] In summary, the advantages of this invention are: 1. The handle is supported by a rotating body inside the cavity and the handle is constrained by a limiting connection hole on the cover plate. On the one hand, the rotating body provides stable support to the handle from the bottom, and the limiting connection hole limits the handle radially from the top. The two work together to effectively limit the shaking, radial offset, and eccentric jump of the handle during the winding process. This avoids problems such as misalignment of the adhesive tape, gaps, and skewed winding caused by the handle shaking, ensuring that the handle always rotates smoothly and centrally, stabilizing the adhesive tape winding benchmark and significantly improving the regularity and forming accuracy of the adhesive tape winding. On the other hand, relying on the rotational characteristics of the rotating body, manual rotation of the handle is smoother, with uniform resistance and no jamming. This makes the rotation rhythm of the handle uniform and stable, effectively avoiding problems such as adhesive tape offset, uneven overlap, and inconsistent winding tightness caused by unstable handle rotation. This further improves the flatness of the adhesive tape winding, while reducing the manual operation force and difficulty, and improving work efficiency. 2. The limit connection hole and the handle are set to clearance fit. When the handle is rotated, the outer wall of the handle contacts the inner wall of the limit connection hole to generate friction. This friction resists the rotation of the handle, thereby stabilizing the tension of the hand glue wrapping and preventing the hand glue from being stretched too loosely or too loosely. This ensures that the tightness of each turn of hand glue wrapping is consistent. In addition, the cover plate can block and seal the opening of the cavity, effectively preventing external dust or debris from entering the cavity. This prevents impurities from accumulating and jamming parts, affecting the handle rotation accuracy and the quality of hand glue wrapping, maintaining the cleanliness of the device, ensuring the long-term stable operation of the whole machine, and extending the service life of the equipment. 3. By setting a strip-shaped groove on the shell that communicates with the cavity, the adhesive tape extends into the cavity through the strip-shaped groove. Therefore, it can guide and limit the adhesive tape, effectively avoiding problems such as skewing, twisting, deviation, and wrinkling during the adhesive tape feeding process. It ensures that the adhesive tape always enters the cavity in a vertical and straight state, ensuring accurate feeding position of the adhesive tape and providing a reliable structural foundation for subsequent bonding, winding, and regular shaping. 4. This handle grip tape wrapping device can meet the grip tape wrapping operations of various handheld rods such as ball handles and racket handles. Moreover, the whole structure is compact and small in size, making it easy to carry and operate on site. Attached Figure Description

[0019] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a handle adhesive wrapping device includes a housing 1 and a cover plate 5. The housing 1 has a cavity 11 with an opening 12 on one side. The cover plate 5 is disposed on the housing 1 and has a limiting connection hole 51. The handle 6 passes through the limiting connection hole 51 with a clearance fit between the limiting connection hole 51 and the handle 6. When the handle rotates, the outer wall of the handle contacts the inner wall of the limiting connection hole to generate friction. The friction is used to stabilize the adhesive wrapping tension. A rotating body 2 for supporting the handle 6 is rotatably connected inside the cavity 11. The side wall of the housing 1 has a strip-shaped through groove 13 communicating with the cavity. The adhesive 7 extends into the cavity 11 through the strip-shaped through groove 13.

[0021] The handle is supported by a rotating body inside the cavity, and its rotation is constrained by a limiting connection hole on the cover. On one hand, the rotating body provides stable support to the handle from the bottom, while the limiting connection hole radially limits the handle from the top. This synergistic effect effectively limits the handle's shaking, radial offset, and eccentric jump during the winding process, preventing problems such as misalignment, gaps, and skewed winding caused by handle vibration. This ensures the handle remains centered and rotates smoothly, stabilizing the wrapping reference and significantly improving the regularity and precision of the wrapping. On the other hand, the rotating characteristics of the rotating body make manual handle rotation smoother, with uniform resistance and no jamming, resulting in a stable and consistent rotation rhythm. This effectively prevents problems such as uneven wrapping, misalignment, and inconsistent winding tightness caused by unstable handle rotation, further improving the flatness of the wrapping while reducing manual effort and difficulty, thus increasing work efficiency. The limiting connection hole and handle are designed with a clearance fit; when the handle rotates, the outer wall of the handle contacts the inner wall of the limiting connection hole, generating friction. The frictional force acts as a counterforce, resisting the rotation of the handle to stabilize the tension of the adhesive wrapping, preventing the adhesive from being stretched too loosely or too loosely, and ensuring that the tightness of each turn of adhesive wrapping remains consistent. Additionally, the cover plate seals the opening of the cavity, effectively preventing external dust or debris from entering the cavity, preventing impurities from accumulating and jamming components, affecting the handle's rotation accuracy and the quality of the adhesive wrapping, maintaining the cleanliness of the device's interior, ensuring long-term stable operation, and extending the equipment's lifespan. A strip-shaped groove on the housing connects to the cavity, through which the adhesive extends into the cavity, thus guiding and limiting the adhesive, effectively preventing problems such as skewing, twisting, deviation, and wrinkling during the adhesive feeding process, ensuring the adhesive always enters the cavity vertically and straight, guaranteeing precise adhesive feeding position, and providing a reliable structural foundation for subsequent bonding, wrapping, and shaping. This handle adhesive wrapping device can meet the adhesive wrapping needs of various handheld rods such as ball handles and racket handles, and its compact structure and small size make it easy to carry and operate on-site.

[0022] A pressure plate 3 is movably connected to the housing 1. The pressure plate can move into the cavity to press the starting end or the ending end of the adhesive onto the outer wall of the handle. Through the pressure plate movably connected to the housing, the starting end of the adhesive or the ending end of the adhesive after winding is pressed tightly against the outer wall of the handle, thus achieving fixed-point fixation of the beginning and end of the adhesive. This effectively overcomes the problems of easy displacement and curling of the starting end and easy loosening and delamination of the ending end in the traditional manual winding method, and avoids defects such as wrinkles, poor adhesion, and loosening of the end during the winding process from the source. Specifically, the housing 1 is provided with a through hole 14, and a spring piece 15 is provided in the through hole 14. The pressure plate 3 is set on the spring piece 15. The pressure plate 3 moves into the cavity 11 by the deformation of the spring piece 15 to press the hand glue, and the pressure plate 3 is reset by the elastic force of the spring piece 15. In use, only a certain pressure needs to be applied to the pressure plate 3 to deform the spring piece 15 and drive the pressure plate 3 to move into the cavity 11 to press the hand glue. After the hand glue is pressed and adhered to the outer wall of the handle 6, the external force applied to the pressure plate 3 is removed, and the pressure plate 3 can automatically reset under the elastic force of the spring piece 15. No additional power is required. The whole structure is compact, occupies little space, and is convenient and labor-saving to operate. It can stably and reliably complete the pressing and positioning of the hand glue, ensuring the uniformity and firmness of the hand glue.

[0023] Two through holes 14 are provided, and the two through holes 14 are respectively located at the upper and lower ends of the housing 1. A pressure plate 3 is installed in each of the two through holes 14. By setting two through holes 14, since the two through holes 14 are respectively located at the upper and lower ends of the housing 1, the upper and lower pressure plates 3 are independent of each other and do not interfere with each other when they are in operation. When in use, the starting position and the ending position of the hand glue can be pressed separately. The starting position and the ending position of the wrapping can be set according to the specific operator to meet different wrapping needs. In this embodiment, the pressure plate 3 at the lower end of the housing 1 is used to press the starting position of the hand glue wrapping, and the pressure plate 3 at the upper end of the housing 1 is used to press the ending position of the hand glue wrapping. The inner wall of the through hole 14 and the pressure plate 3 have a first single-sided gap 4 of 0.2mm to 1mm, which can ensure that the pressure plate 3 moves flexibly under the action of the spring piece 15, and the pressing and resetting actions of the pressure plate 3 are smooth and without jamming. When the first single-sided gap 4 is less than 0.2mm, the pressure plate 3 is prone to jamming. When the first single-sided gap 4 is greater than 1mm, the pressure plate 3 is prone to shaking when moving. In this embodiment, a first single-sided gap 4 of 0.6mm is preferred, which can effectively ensure the pressing accuracy and working stability of the pressure plate 3, thereby ensuring uniform pressing and bonding of the hand glue and improving the overall forming quality of the hand glue wrapping.

[0024] The cover plate 5 is detachably installed on the housing 1. It has a simple structure. When in use, simply opening the cover plate 5 allows for quick placement and removal of the handle 6 without causing spatial interference. The handle loading and unloading operation is simple. In addition, it facilitates the inspection and maintenance of the rotating body 2. Moreover, different cover plates 5 can be installed according to different types of handles 6 to meet different operational needs. In this embodiment, the bottom end of the cover plate 5 is provided with a protrusion that extends into the cavity 11. The assembly and installation of the cover plate 5 are achieved by the cooperation between the protrusion and the cavity 11, which greatly simplifies the installation structure of the cover plate 5. No additional fastening structure is required. Not only is disassembly and assembly convenient, but the connection of the cover plate 5 after assembly is also reliable, effectively ensuring the overall assembly stability of the device. The limiting connection hole 51 and the handle 6 have a second single-sided gap of 0.1mm to 0.5mm. The setting of the second single-sided gap can ensure that the inner wall of the limiting connection hole and the outer wall of the handle are in continuous slight contact. During rotation, a stable and uniform friction force can be generated. This friction force is used to resist the rotation of the handle and stabilize the wrapping tension of the adhesive. It will not cause the two to separate due to excessive gap, resulting in uncontrolled tension without damping. If the second single-sided gap is less than 0.1mm, the limiting connection hole and the handle are too tightly fitted, the friction resistance increases significantly, the handle is difficult to rotate and jams, and the adhesive is easy to stretch and thin, and the elasticity is damaged. If the second single-sided gap is greater than 0.5mm, the handle has a large amount of movement in the hole, and it is easy to eccentrically shake during rotation. The hole wall and the handle are in intermittent contact, the friction force fluctuates, the wrapping tension fluctuates, and uneven tightness and misalignment occur. In this embodiment, the wrapping tension of the adhesive is controlled at 0.2Nm to 0.4Nm by the cooperation of the second single-sided gap. In this embodiment, a notch connected to the limiting connection hole can be provided on the cover plate, so that the cover plate can be installed and removed from the side.

[0025] The rotating body 2 includes a rotating shaft 21 and a support plate 22. The support plate 22 is disposed on the rotating shaft 21, which is rotatably connected to the cavity 11 via a bearing 23. Because the rotating shaft 21 is rotatably connected to the cavity 11 via the bearing 23, the bearing 23 reduces the frictional resistance of the rotating shaft 21, ensuring smooth and uninterrupted rotation. This significantly reduces the resistance when manually rotating the handle 6, making manual rotation easier and smoother, and avoiding problems such as unstable winding rhythm caused by rotational jamming or excessive resistance. Simultaneously, the support plate 22 stably supports the bottom of the handle 6, ensuring stable support during manual rotation and preventing the handle 6 from wobbling, effectively improving the uniformity and regularity of the manual winding process. In this embodiment, the housing 1 is provided with mounting holes, and the bearing 23 is installed in the mounting holes. In this embodiment, the rotating shaft 21 and the support plate 22 are an integral structure, which simplifies the installation process between the rotating shaft 21 and the support plate 22, improves the connection strength between the rotating shaft 21 and the support plate 22, reduces the assembly error between the rotating shaft 21 and the support plate 22, and improves the stability of the entire rotating body 2.

[0026] The outer wall of the housing 1 is provided with scale markings 16. These markings allow operators to accurately determine the wrapping position and length of the adhesive tape. During use, operators can refer to the scale markings 16 for standardized wrapping, precisely controlling the starting and ending positions of the adhesive tape, as well as the overlap of each layer. This effectively avoids problems such as wrapping deviation, uneven overlap, local gaps, or excessive overlap, ensuring consistent wrapping, preventing waste, and saving on usage costs. In this embodiment, the wrapping distance per turn can be controlled to be 15-17mm via the scale markings 16, with 16mm being preferred. The cavity 11 contains a support column 17 for storing the adhesive tape roll, allowing for centralized placement and convenient retrieval by the operator during the wrapping process. In this embodiment, a strip-shaped groove is provided along the height of the housing to facilitate the insertion of the adhesive tape.

[0027] In addition to the preferred embodiments described above, there are other embodiments of the present invention. Those skilled in the art can make various changes and modifications based on the present invention, and all such changes and modifications should fall within the scope defined by the appended claims, as long as they do not depart from the spirit of the present invention.
