A film-coated transfer tool

Abstract

A coating transfer tool includes a housing, a transmission assembly, a transfer head, and a contact member and a mating member. The transmission assembly includes a winding pulley and a take-back pulley, with a winding reel on the winding pulley. The transfer head is adapted to move relative to the housing between a first position and a second position. The contact member abuts against the transmission assembly to provide braking force during the movement of the transfer head. The mating member is adapted to move relative to the contact member to allow the transfer head to move from the second position to the first position. The pressure applied by the user is adjusted by an elastic member to automatically regulate the tape strength, achieving a relatively balanced tape application force before and after use. After coating is completed, the elastic member automatically locks the transmission mechanism, achieving "ready to use and ready to use" and a smooth coating at the beginning and end of the coating process. An anti-rotation part ensures relative quiet operation, avoiding environmental noise disturbance, and effectively locking the transmission mechanism during carrying and transportation.

Description

Technical Field

[0001] This invention belongs to the field of coating transfer tool technology, and specifically relates to a coating transfer tool. Background Technology

[0002] A coating transfer printing machine is an office supply consisting of a core tray (including the transfer tape), a waste tape tray, a transfer head, and a housing. The transfer tape is pulled out from the core tray and passes through the transfer head to transfer the coating onto the corresponding substrate. After use, the waste tape is collected through the waste tape tray.

[0003] However, existing coating transfer printing tools have the following problems: 1. As the product is used, the diameter of the transfer tape wound on the winding reel and waste tape reel will change accordingly, thus affecting the user's tactile experience. This is mainly reflected in the fact that the initial section of the tape is relatively loose (because the initial resistance is small, so a habitually weaker tape application force is used for the transfer, resulting in a relatively poor flatness of the applied substrate), while the later section is relatively tight (because the resistance at the end is greater, a stronger tape application force is required for the transfer, affecting the user's tactile experience). The difference in tactile experience between the beginning and end is quite obvious.

[0004] 2. Generally, if there is no reasonable cutting action after coating on the coating transfer tool (after coating is completed, press the transfer head hard and then lift the product), it will affect the coating effect at the end and also have a negative impact on the next coating. This is mainly reflected in the unevenness of the coating at the beginning and end of the coating. Summary of the Invention

[0005] (a) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this invention is to provide a coating transfer tool to solve the existing problems. (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a coating transfer tool, comprising a housing, a transmission assembly disposed within the housing, a transfer head movably disposed on the housing, and an abutment member and a mating member; The transmission assembly includes a winding wheel and a recovery wheel that is connected to the winding wheel in a transmission drive. The winding wheel is provided with a winding reel. The transfer head is adapted to move relative to the housing between a first position and a second position. The abutment abuts against the transmission assembly and is configured to engage with the transmission assembly to provide braking force when the transfer head moves between the first position and the second position. The engaging member is adapted to move relative to the abutment to allow the transfer head to move from the second position toward the first position.

[0006] As a further improvement, when the transfer head moves relative to the housing between a first position and a second position, the abutment provides the transmission assembly with a frictional force that changes synchronously with the movement of the transfer head.

[0007] As a further improvement, the abutting member has elastic force and abuts against the mating member and the transmission assembly respectively, for the springback reset of the transfer head and the abutting engagement with the transmission assembly. The transfer head can move relative to the housing, thereby allowing the abutting member to switch between elastic energy release and energy storage states.

[0008] As a further improvement, the abutting member has a first elastic part and a second elastic part that generate different elastic force changes according to different abutting forces; the first elastic part and the second elastic part abut against the mating member and the transmission assembly respectively, and when one of the first elastic part and the second elastic part is abutted and is in an elastic energy storage state, the other will be in an elastic energy release state.

[0009] As a further improvement, when the transfer head moves between the first position and the second position relative to the housing, the second elastic part and the transmission assembly always maintain a contacting engagement state.

[0010] As a further improvement, the mating member abuts against the outside of the first elastic part, allowing the first elastic part to control the elastic force generated by the movement relative to the housing; one end of the second elastic part is connected to the abutting member, and the other end abuts against the transmission assembly, allowing the second elastic part to control the abutting fit with the transmission assembly.

[0011] As a further improvement, the abutting member has a second elastic part that generates different elastic force changes according to different abutting forces and a magnetically attracted part that is magnetically connected to the mating member; the second elastic part abuts against the transmission assembly, and the magnetically attracted part and the mating member maintain a state of magnetic attraction or magnetic repulsion.

[0012] As a further improvement, when the transfer head moves between the first position and the second position relative to the housing, the magnetic attraction part and the mating part are attracted or repelled by magnetism, so that the second elastic part is in an elastic energy storage or elastic energy release state.

[0013] As a further improvement, the second elastic part always abuts against the transmission assembly.

[0014] As a further improvement, the magnetic attraction part and the mating part are made of magnets with the same poles to maintain magnetic repulsion.

[0016] As a further improvement, one end of the abutment is connected to the transfer head, thereby causing the transfer head to drive the abutment to move synchronously relative to the housing. The mating part is correspondingly provided on the housing to control the springback reset of the abutment.

[0017] As a further improvement, a number of movable grooves or positioning posts are provided between the abutment and the transfer head, and corresponding positioning posts or movable grooves that cooperate with the limiting function are provided on the housing.

[0018] As a further improvement, it also includes a movable component movably disposed within the housing, with the mating component correspondingly disposed on the movable component, the housing having an opening, and the transfer head being disposed at one end of the movable component near the opening.

[0019] As a further improvement, one end of the transfer head is connected to the movable part, and the other end extends through the opening, so that the transfer head can drive the movable part to move synchronously relative to the shell, so that the contact part switches between elastic energy release and elastic energy storage states.

[0020] As a further improvement, a plurality of mating holes corresponding to the second elastic part are provided on the movable part, and the mating holes allow one end of the second elastic part to pass through and abut against the transmission assembly.

[0021] As a further improvement, a guide portion is provided between the housing and the movable part, through which the movable part can move relative to the housing. The guide portion includes a guide groove provided on either the housing or the movable part, and a guide bar provided on the other part that slides in cooperation with the guide groove.

[0022] As a further improvement, a limiting part is also provided between the housing and the movable part. The movable part can control the movement distance relative to the housing through the limiting part. The limiting part includes a first limiting part provided on either the housing or the movable part, and a second limiting part provided on the other to limit and cooperate with the first limiting part.

[0023] As a further improvement, the second limiting member is disposed within the vertical projection range of the first limiting member. When the movable member moves relative to the housing, the second limiting member moves within the vertical projection range of the first limiting member.

[0024] As a further improvement, the first limiting member is a limiting frame provided on the housing, and the second limiting member is a limiting protrusion provided on the movable member. The limiting protrusion extends and protrudes towards the limiting frame and abuts against the inner side of the limiting frame.

[0025] As a further improvement, the second elastic portion of the abutment abuts against the winding disc in the transmission assembly.

[0026] As a further improvement, the displacement distance between the transfer head and the housing is 0.05~2.0mm.

[0027] As a further improvement, a positioning part is provided between the housing and the abutment, which fixes the abutment to the housing to limit the vertical and horizontal displacement of the abutment relative to the housing.

[0028] As a further improvement, the positioning part fixes the abutment to the housing and limits its vertical position, and the abutment and the housing are in a clearance fit or sliding fit in the lateral direction, so that the abutment can be pushed in the lateral direction of the housing.

[0029] As a further improvement, the positioning part includes a positioning groove provided on either the housing or the abutment member, and a positioning block provided on the other to be adapted to limit the positioning groove.

[0030] As a further improvement, the housing or movable part is provided with a number of guide posts, and the winding wheel and the recovery wheel are respectively rotatably mounted on the number of guide posts.

[0031] As a further improvement, a transmission wheel is provided between the winding wheel and the recovery wheel, and the winding wheel and the recovery wheel are connected by the transmission wheel.

[0032] As a further improvement, it also includes an anti-rotation part, which includes an elastic element with elastic restoring force disposed on either the housing or the moving part, and a movable hole for elastic deformation space of the elastic element, the end of the elastic element engaging unidirectionally with the gear structure of the recovery wheel.

[0033] As a further improvement, the movable hole is provided on the movable part, and the elastic element is correspondingly provided in the movable hole. A positioning element that cooperates with the elastic element is provided on the housing. When the movable part moves relative to the housing, the positioning element abuts and pushes the elastic element to deform in the movable hole until the elastic element disengages from the recovery wheel.

[0034] As a further improvement, the end of the elastic element is specifically provided with ratchet teeth that mesh unidirectionally with the gear structure of the recovery wheel.

[0035] (III) Beneficial Effects The beneficial effects of this invention are: 1. By adjusting the pressure applied by the user, the belt force is automatically adjusted under the action of the contact element, thereby achieving a relatively balanced belt force before and after use.

[0036] 2. After the coating is applied, the coating transfer tool automatically locks the transmission mechanism under the action of the abutment, thereby achieving a "use and lift" effect and a smooth coating effect at the beginning and end of the coating process.

[0037] 3. During use, the anti-rotation part achieves a relatively quiet effect, avoiding environmental noise interference. During carrying and transportation, it can effectively lock the transmission components, ensuring that the coating transfer tool core is flat and does not fall apart. Attached Figure Description

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1 like Figure 1 , 2 As shown in Figures 3 and 4, the structure of a coating transfer tool according to an embodiment of the present invention will be described in detail. It includes a housing 1, a transmission assembly 4 disposed inside the housing 1, a transfer head 6 movably disposed on the housing 1, and an abutment 2 and a mating part 7. The housing 1 has an accommodating space inside for placing the transmission assembly 4 and the abutment 2 therein, and can provide a certain amount of space for movement. It should be noted that the abutment 2 and the housing 1 can be a separate solution or an integrated solution. That is, the abutment 2 can be a separate component or a component disposed at any position on / inside the housing 1. In this embodiment, the abutment 2 is specifically disposed as a separate component inside the housing 1.

[0042] The transmission assembly 4 includes a winding wheel 41 and a recovery wheel 42 that is connected to the winding wheel 41. The winding wheel 41 is provided with a winding disc 43. The housing 1 has an opening 11. The transfer head 6 is provided at one end of the housing 1 near the opening 11. A transfer tape 45 is wound on the winding disc 43. The transfer tape 45 is wound from the winding disc 43, through the transfer head 6, and then wound onto the recovery wheel 42. The transfer head 6 is adapted to move relative to the housing 1 between a first position and a second position. The abutting member 2 abuts against the transmission assembly 4 and is provided to provide braking force when the transfer head 6 moves between the first position and the second position. This braking force can restrict the transmission assembly 4. The mating member 7 is adapted to move relative to the abutting member 2 so that the transfer head 6 moves from the second position to the first position. When the transfer head 6 moves relative to the housing 1 between the first position and the second position, the abutting member 2 provides the transmission assembly 4 with a frictional force that changes synchronously with the movement of the transfer head 6. This frictional force is the braking force provided above and is used to control the static and dynamic frictional forces generated by the static and dynamic states of the transmission assembly. The first position is the initial state when the transfer tool is not in use or the static state after use. The second position is when the transfer tool is in use, and the transfer head 6 moves relative to the housing 1 to any position different from the first position. In this embodiment, the transfer head 6 will be displaced between the first position and the second position.

[0043] In this embodiment, the abutting member 2 has a certain elastic force and abuts against the mating member 7 and the transmission component 4 respectively, providing for the springback reset of the transfer head 6 and the abutting engagement with the transmission component 4. The transfer head 6 can move relative to the housing 1 (the transfer head 6 moves between the first position and the second position), thereby causing the abutting member 2 to switch between elastic energy release and energy storage states. That is to say, by changing the movement state, the abutting force between the abutting member 2 and the mating member 7 and the transmission component 4 changes accordingly, and the abutting member 2 can switch between elastic energy release and elastic energy storage states. This change in abutting force is generated when the transfer head 6 moves relative to the housing 1. It should be noted that this elastic energy is the switching between elastic energy release and elastic energy storage states when the abutting member 2 with elastic force is deformed, compressed or stretched by the abutting force. When the abutting member 2 is in the elastic energy release state relative to the transmission component 4, the braking force it provides to the transmission component 4 gradually decreases, and vice versa.

[0044] Please see Figure 4As shown, when the transfer head 6 is stationary (the transfer tool is not in use or has been used up), the abutment 2 provides the transmission assembly 4 with a maximum frictional pressure, that is, the abutment 2 tightly abuts against the transmission assembly 4; when the transfer head 6 moves relative to the housing 1, the abutment 2 is in an elastic energy storage state relative to either the mating part 7 or the transmission assembly 4, and the abutment 2 will be in an elastic energy release state relative to the other of the mating part 7 and the transmission assembly 4. That is to say, when the transfer head 6 moves relative to the housing 1, the mating part 7 and the transmission assembly 4 that the abutment 2 abuts against will generate a corresponding change in abutment force according to their movement distance. As a result, the abutment 2 switches between an elastic release state and an elastic compression state according to this change in force. That is, when the transfer head 6 moves relative to the housing 1, the mating part 7 and the transmission assembly 4 abut against and squeeze the abutment 2, resulting in a change in elastic force.

[0045] Please see Figure 4 , 5 As shown in Figure 6, in a preferred embodiment, the abutting member 2 has a first elastic part 21 and a second elastic part 22 that generate different elastic force changes according to different abutting forces. The first elastic part 21 and the second elastic part 22 abut against the mating member 7 and the transmission assembly 4, respectively. When one of the first elastic part 21 and the second elastic part 22 is in an elastic energy storage state under abutment, the other will be in an elastic energy release state. Specifically, when the transfer head moves from the first position to the second position, the abutting member 2 is in an elastic energy release state relative to the transmission assembly; when the transfer head moves from the second position to the first position, the abutting member 2 is in an elastic energy storage state; and when it is fully moved to the first position, the abutting member 2 provides... In a preferred embodiment, the second elastic part 22 of the abutment member 2 abuts against the winding disc 43 in the transmission assembly 4, and preferably against the inner wall of the winding disc 43. It should be noted that in this embodiment, when the transfer head 6 moves relative to the housing 1 between the first position and the second position, the second elastic part 22 and the transmission assembly 4 always maintain an abutment engagement state and remain in a non-separated state. That is to say, when the transfer head 6 moves relative to the housing 1 to the point where the first elastic part 21 is at its maximum elastic energy, the second elastic part 22 still abuts against the transmission assembly 4, and is in a state of minimum elastic force relative to the transmission assembly 4.

[0046] It should be noted that the mating part 7 is a horizontal surface that is perpendicular to the displacement direction of the abutting part 2. It can be the inner wall of a groove structure or the outer wall of a protrusion structure. That is to say, the horizontal surface where the mating part 7 and the abutting part 2 abut against any inner / outer wall is located is perpendicular to the displacement direction of the abutting part 2. It can be provided at any position inside or outside the housing 1 and on the housing 1. Specifically, in this embodiment, the mating part 7 is a protrusion structure, which is provided on the inner wall of the housing 1 and extends downward toward the transmission assembly 4 to a suitable distance. The outer wall of the mating part 7 abuts against the abutting part 2.

[0047] Its effects are as follows: When the transfer head 6 is stationary in the first position (transfer tool not in use), the second elastic part 22 will provide a maximum abutting preload to the winding reel 43. This maximum abutting preload can prevent the transfer belt 45 from being easily rotated, and will not cause the internal winding reel 43 to loosen due to shaking during transportation or handling, thus preventing a decrease in the tape application experience. When the transfer head 6 is pressed, causing the abutting member 2 to move between the first and second positions (transfer tool in use), the mating member 7 abutted by the first elastic part 21 will move relative to it (the first elastic part 21). 1) Gradually press and squeeze, the first elastic part 21 will be in an elastic energy storage state after being pressed and squeezed, while the second elastic part 22 is in an elastic release state due to the relative movement of the transfer head 6, which makes the pressing force of the winding disc 43 on the second elastic part 22 gradually decrease. This setting provides a progressive operating experience for the user's tape transfer operation, and the tape is smoother. The tape force is automatically adjusted by the action of each component according to the pressure change applied by the user, so as to achieve a relatively balanced tape force before and after use.

[0048] Please see Figure 4 , 7As shown, the mating part 7 abuts against the outer side of the first elastic part 21, providing the first elastic part 21 with elastic force to control the movement of the relative housing 1; one end of the second elastic part 22 is connected to the abutting part 2, and the other end abuts against the transmission assembly 4, providing the second elastic part 22 with elastic force in the displacement direction relative to the housing 1, so as to control the frictional force generated by the rotation of the transmission assembly 4. That is, when the transfer head 6 moves relative to the housing 1 (when using the transfer tool for transfer or after transfer), since the abutting part 2 moves synchronously to the rear or front side with the transfer head 6, one end of the second elastic part 22 abuts against the winding reel 43. The second elastic part 22 is first subjected to the abutting pressure of the winding reel 43 and generates elastic force accordingly, and is in an elastic energy storage or elastic energy release state. At the same time, the winding reel 43 is also wrapped with transfer tape; when using the transfer tool for transfer, through the transmission... The transmission between the moving components 4 causes the winding reel 43 to rotate during the transfer process. Therefore, the second elastic part 22 is also subjected to a frictional force generated by the rotation. At this time, the elastic force generated by the second elastic part 22 can be used to resist the frictional force generated by the rotation of the winding reel 43. The greater the elastic force generated by the second elastic part 22, the greater the frictional force (braking force) of the winding reel 43 on the second elastic part 22, and vice versa. After the transfer tool is used or not used, the second elastic part 22 will provide the winding reel 43 with the maximum elastic force, so that the frictional force (braking force) reaches the maximum, thereby ensuring that the winding reel 43 and the winding wheel 41 will not be easily rotated. After the coating transfer tool is applied, under the action of this component, the transmission component 4 can be automatically locked, thereby achieving the effect of "ready to use and ready to use" and smooth coating at the beginning and end of the coating.

[0049] It should be noted that in this example, the side facing the opening 11 of the housing 1 is defined as the front side, and the side facing the abutment 2 is defined as the rear side. Since the displacement distance of the transfer head 6 and the corresponding change in elastic force generated by the abutment 2 during displacement are related to the force applied by the user when pressing, the greater the force applied by the user, the less friction the winding disc 43 experiences, and the smoother the tape application. Conversely, the greater the force required for tape application, thus providing the user with a progressive tape application experience. In this embodiment, a fixing platform 30 is also provided at the front end of the housing 1, in which the transfer head 6 can be inserted. The fixing platform 30 allows for easy disassembly and installation of the transfer head 6 to address the situation where the transfer head 6 needs to be replaced due to damage. It also makes the displacement of the transfer head 6 more stable and prevents it from shaking, and allows the transfer head 6 to be quickly positioned and installed, thereby improving the efficiency of disassembly and installation.

[0050] In a preferred embodiment, the displacement distance between the transfer head 6 and the housing 1 is 0.05~2.0mm. In this embodiment, the displacement distance range of the transfer tool is preferably controlled within the range of 0.05-0.35mm. Controlling this range makes the tool more sensitive when drawing the tape, providing users with a better and more comfortable experience. The elastic force between the first elastic part 21 and the second elastic part 22 changes with the displacement, thereby providing users with a more comfortable and smooth tape drawing experience.

[0051] Please see Figure 4 , 6 As shown in Figure 7, the first elastic part 21 includes at least one elastic sheet 211 extending toward the mating member 7. In this embodiment, the first elastic part 21 specifically has two bent and extended elastic sheets 211, the top of which abuts against one side of the mating member 7. The second elastic part 22 includes at least one elastic arm 221 extending toward the winding reel 43. In this embodiment, the second elastic part 22 specifically has two elastic arms 221 arranged in a front-to-back manner. The ends of the two elastic arms 221 abut against the inner wall of the winding reel 43 and the inner wall of the winding reel 43 of the transmission assembly 4. Specifically, in this embodiment, the elastic arm 221 extends toward the winding reel 43, and its end bends and extends toward and abuts against the inner wall of the winding reel 43.

[0052] It should be noted that, in the initial state, the rear elastic arm 221, positioned at the front and rear, abuts against the inner wall of the winding reel 43, placing it in a state of elastic compression and frictional pre-tension. The front elastic arm 221, however, remains stationary, not abutting against the inner wall of the winding reel 43. When the transfer head 6 moves rearward relative to the housing 1, the rear elastic arm 221 gradually returns to its original state, releasing its elasticity, while the front elastic arm 221 gradually moves towards the inner wall of the winding reel 43 until it abuts against it. At this point, the front elastic arm 221 can also provide elastic support for the winding reel. The tape reel 43 provides a resisting force. Even if the user makes an operational error and applies too much force, causing the rear elastic arm 221 to detach from the inner wall of the tape reel 43, the front elastic arm 221 still provides frictional force. This further prevents excessive difference in front and rear frictional force caused by operational errors, thereby improving the coating effect of the transfer tool. In some preferred embodiments, the front elastic arm 221 can be eliminated, and only the rear elastic arm 221 provides elastic force. However, the elastic arm 221 is always in contact with the inner wall of the tape reel 43 and remains in a non-detached state even after the transfer head 6 has completed its displacement.

[0053] Please see Figure 2 , 3As shown in Figure 4, in order to enable the transfer head 6 to synchronously drive the abutment 2 to move relative to the housing 1, one end of the abutment 2 is connected to the transfer head 6, thereby enabling the transfer head 6 to drive the abutment 2 to move synchronously relative to the housing 1. It should be noted that the connection between the transfer head 6 and the abutment 2 can be made into a single piece for permanent connection, or it can be a separate detachable connection. In this embodiment, a single piece connection is preferred, thereby enabling the transfer head 6 to drive the abutment 2 to move synchronously relative to the housing 1. At the same time, the mating part 7 in this embodiment is correspondingly fixed on the housing 1 to control the springback reset of the abutment 2.

[0054] Please see Figure 5 , 6 As shown in Figure 7, a plurality of movable grooves 51 or positioning posts 52 are provided between the abutment 2 and the transfer head 6. The housing 1 is provided with corresponding positioning posts 52 or movable grooves 51 that are limited and matched with them. The limited matching means that the positioning posts 52 and the movable grooves 51 can form a certain sliding matching relationship and move within a certain range. Specifically, the abutment 2 and the transfer head 6 include a connecting frame 50 extending from the abutment 2 toward the transfer head and a plurality of movable grooves 51 formed on the connecting frame 50. The housing 1 is provided with positioning posts 52 that are limited and matched with the movable grooves 51. It should be noted that in this embodiment, one end of the transfer head 6 is connected to the connecting frame 50, and the other end extends through the opening 11. That is to say, when in use, the transfer head 6 can be pressed through the opening 11 to simultaneously drive the abutment 2 to move. Therefore, the displacement distance between the transfer head 6 and the abutment 2, and the corresponding change in elastic force generated by the abutment 2 during displacement, are related to the force applied by the user when pressing.

[0055] It should be noted that the shell 1 in this embodiment can also adopt an integrated connection structure or a split connection structure. Specifically, it will adopt an upper and lower split connection structure. The upper and lower shells 1 can be fixed by any of the following methods, including but not limited to snap-fit ​​fixing, screw fixing, insertion fixing, ultrasonic heat fusion fixing, pivot hole fixing, and hinge fixing.

[0056] Detailed instructions for use are as follows: Please see Figures 1-8 As shown, specifically, in the initial stage when the transfer head 6 is in the first position (the transfer tool is not in use), the transfer head 6 is in a stationary state. In this embodiment, the first elastic part 21 abuts against the mating part 7 and is in an elastic energy release state (the first elastic part 21 is not deformed or compressed), while the second elastic part 22 abuts against the winding reel 43 and is always in an elastic energy storage state (deformation and compression energy storage), and provides the winding reel 43 with a maximum abutment preload force, which can prevent the internal transmission component 4 from being easily rotated when the transfer tool is handled or picked up. During the usage phase, the transfer head 6 is in a displacement state between the first and second positions (transfer tool usage state). When the user increases the pressing pressure, causing the transfer head 6 (which drives the contact member 2 to move synchronously) to move rearward relative to the housing 1, the mating member 7 gradually abuts against and squeezes the first elastic part 21 (i.e., the applied pressing pressure overcomes the rebound effect of the first elastic part 21 through the mating member 7). Consequently, the first elastic part 21 is compressed and gradually changes from an elastic energy release state to an elastic energy storage state, while the winding reel 43 gradually reduces the contact force with the second elastic part 22. The second elastic part 22 gradually changes from an elastic energy storage state to an elastic energy release state, that is, the second elastic part 22 gradually returns to its original state (uncompressed state). This design allows the user to adjust their own application resistance according to the changes in their own application force when applying the transfer tape, so as to achieve a balanced application force effect of "weak in one part and strong in the other". In this way, it solves the common problem of the front part of the tape being relatively loose and the back part being relatively tight due to the change in the diameter of the transfer tape wound on the tape reel and waste tape reel of the coating transfer tool.

[0057] In the final stage, the transfer head 6 is in a state where the displacement of a certain second position at its maximum value has been completed (transfer instrument usage state). After the displacement is completed, the second elastic part 22 still abuts against the winding reel 43, and its elastic force relative to the winding reel 43 is at its minimum. That is to say, in this stage, the second elastic part 22 is close to being completely disengaged but has not yet disengaged. At this time, the abutting and squeezing force of the second elastic part 22 on the winding reel 43 is close to zero. Since the transfer belt of a conventional transfer instrument is in a relatively taut state during use, the transmission component and the winding wheel of a conventional transfer instrument need to be in a state of compression and friction pre-tension to balance the taut state of the transfer belt. However, this application uses the second elastic part 22 to control the winding belt... The pre-tightening force of the disc 43, together with the extrusion friction pre-tightening force of the transmission component 4 and the winding disc 43, balances the force on the transfer belt when it is taut. Therefore, when the pressure on the taut transfer belt remains unchanged, and the pressure of the second elastic part 22 against the winding disc 43 approaches zero, the extrusion friction pre-tightening force between the transmission component 4 and the winding disc 43 is smaller than that of a conventional transfer tool. Consequently, the user needs to apply less pressure when applying the belt, making it more effortless. At the same time, because the second elastic part 22 of this invention is not completely detached from the winding disc 43, the friction force when the user applies the belt will not have too large a difference between front and back, and a small reverse force is maintained in normal conditions, which can better improve the application effect.

[0058] After use, the transfer head 6 returns to the first position. Through the elastic force of the first elastic part 21 against the mating part 7, the transfer head 6 gradually moves relative to the front side of the housing 1. At this time, the first elastic part 21 gradually releases elastic energy, and the second elastic part 22 is also gradually compressed and returns to the state of maximum abutment pressure when the transfer tool is not in use. Because of the action of the first elastic part 21, after each scribbling is completed, the transfer head 6 will be returned to its original position by the second elastic part 22 of the mating part 2. The second elastic part 22 will also return to the state of maximum abutment pre-tightening force on the winding reel 43, so that the transmission component 4 and the winding reel 43 are in a state similar to self-locking. After the scribbling is completed, the user does not need to deliberately press the transfer head hard and then lift the product. Its coating will also be smoother than the broken part of the conventional scribbling transfer tool. At the same time, it reduces the adverse effects on the next scribbling, mainly reflected in the smoothness of the coating at the beginning and end of the scribbling.

[0059] It should be noted that in this embodiment, the springback reset function of the first elastic part 21 and the friction control function of the second elastic part 22 are integrated into the abutment part 2 as one unit. In actual production, there are no part manufacturing tolerances or assembly tolerances, thus improving sensitivity and positioning accuracy. Even when the part is damaged, replacement is more convenient. Only the abutment part 2 needs to be disassembled and replaced. Not only is the assembly efficiency fast, but the replacement efficiency is also fast when damaged.

[0060] Please see Figures 1-5 As shown, a positioning part is provided between the housing 1 and the abutment 2. The positioning part fixes the abutment 2 to the housing 1 to limit the vertical and horizontal displacement of the abutment 2 relative to the housing 1. That is, the abutment 2 can be completely fixed to the housing 1 or fixed in only one direction, while displacement can occur in the other direction.

[0061] In this embodiment, the positioning part fixes the abutment 2 to the housing 1 and limits its vertical position. The abutment 2 and the housing 1 are in a clearance fit or sliding fit in the lateral direction, so that the abutment 2 can be pushed in the lateral direction of the housing 1. Thus, the abutment 2 can not only be fixed to the housing 1, but also move synchronously with the transfer head 6.

[0062] Please see Figure 3 , Figure 5Specifically, the positioning part includes a positioning groove 108 provided on either the housing 1 or the abutment member 2, and a positioning block 109 correspondingly provided on the other, which is adapted to limit the positioning groove 108. As a preferred embodiment, the positioning groove 108 is provided on the abutment member 2, while the positioning block 109 is correspondingly provided on the housing 1. The positioning block 109 and the positioning groove 108 are engaged by a snap-fit, and the abutment member 2 is fixed to the housing 1 by the snap-fit ​​between the positioning block 109 and the positioning groove 108. At the same time, the positioning block 109 and the positioning groove 108 have space in the lateral direction to facilitate the lateral displacement of the abutment member 2. Please see Figure 5 , 7 As shown, in this embodiment, the housing 1 is provided with a plurality of guide posts 31, and the winding wheel 41 and the recovery wheel 42 are respectively rotatably mounted on the plurality of guide posts 31. In order to ensure the transmission effect between the transmission components, a transmission wheel 44 is also provided between the winding wheel 41 and the recovery wheel 42. The winding wheel 41 and the recovery wheel 42 are connected by transmission through the transmission wheel 44. The winding wheel 41, the recovery wheel 42 and the transmission wheel 44 can be connected by transmission through a method including but not limited to gear structure transmission, belt pulley transmission and magnetic attraction transmission. The transmission method between the transmission components 4 is similar to the prior art, so it will not be described in detail here.

[0063] Example 2 like Figure 9 , 10 As shown, in another preferred embodiment of the present invention, the coating transfer tool of this embodiment includes a housing 1, a movable member 3 movably disposed within the housing 1, a transmission assembly 4 disposed on the movable member 3, and an abutment member 2 disposed between the movable member 3 and the housing 1. The housing 1 has an accommodating space for placing the movable member 3, the transmission assembly 4 and the abutment member 2 therein, and can provide a space for the movable member 3 to move. The movable member 3 can drive the transmission assembly 4 to move relative to the housing 1 within the space. In this embodiment, the mating member 7 is specifically a protrusion structure, which is disposed on the outer wall of the movable member 3 and extends upward toward the inner wall of the housing 1 to a suitable distance. The outer wall of the mating member 7 abuts against the abutment member 2. The transmission assembly 4 includes a winding wheel 41 and a recovery wheel 42 that is connected to the winding wheel 41 in a transmission manner. The winding wheel 41 is provided with a winding disc 43. The movable part 3 is provided with a transfer head 6 at the end away from the winding wheel 41. A transfer tape 45 is wound on the winding disc 43. The transfer tape 45 is wound from the winding disc 43, through the transfer head 6, and then wound onto the recovery wheel 42. It should be noted that the abutting member 2 in this embodiment also has elastic force and abuts against the movable member 3 and the winding reel 43 respectively. The movable member 3 can be in a stationary or moving state relative to the housing 1 synchronously with the transfer head 6. That is, when the transfer head 6 moves between the first and second positions, the movable member 3 moves synchronously accordingly. However, the abutting member 2 in this embodiment differs from that in embodiment 1; it is fixed to the housing 1 and does not move synchronously with the transfer head 6. The change in movement state causes the abutting force between the abutting member 2 and the movable member 3 and the winding reel 43 to change accordingly, allowing the abutting member 2 to switch between elastic energy release and elastic energy storage states. This change in abutting force is generated when the movable member 3 is displaced relative to the housing 1. When the movable member 3 is stationary (when the transfer head 6 is in the first position), the abutting member 2 provides a maximum abutting preload to the winding reel 43. A large pre-tightening force prevents the transfer belt from rotating easily and prevents the internal winding reel 43 from loosening due to shaking during transportation or handling, thus avoiding a decrease in the tracing experience. When the movable part 3 is in motion (when the transfer head 6 moves between the first and second positions), the abutting part 2 is in an elastic energy storage state relative to either the movable part 3 or the winding reel 43, and the abutting part 2 will be in an elastic energy release state relative to the other of the movable part 3 and the winding reel 43. That is, when the movable part 3 is displaced relative to the housing 1, the abutting force between the movable part 3 and the winding reel 43 abutted by the abutting part 2 will change accordingly based on its displacement distance. Consequently, the abutting part 2 switches between an elastic energy release state and an elastic energy storage state based on this force change. In other words, when the movable part 3 is displaced relative to the housing 1, the movable part 3 and the winding reel 43 abut against and squeeze the abutting part 2, resulting in a change in elastic force.

[0064] Please see Figure 9 , 10As shown in Figure 14, in a preferred embodiment, the housing 1 has an opening 11. A transfer head 6 is provided at one end of the movable member 3 near the opening 11. One end of the transfer head 6 is connected to the movable member 3, and the other end extends through the opening 11. The transfer head 6 can then drive the movable member 3 to move synchronously relative to the housing 1, causing the abutment member 2 to switch between elastic energy release and elastic energy storage states. In other words, during use, the transfer head 6 can be pressed through the opening 11 to synchronously drive the movable member 3 to move. Therefore, the displacement distance of the movable member 3 and the corresponding change in elastic force generated by the abutment member 2 during displacement are related to the force applied by the user when pressing. It should be noted that the transfer head 6... The movable part 3 can be manufactured as a single piece or connected separately. In this embodiment, it is specifically connected separately. In this embodiment, a fixed platform 30 is provided at the front end of the movable part 3, which can insert the transfer head 6 into it. The fixed platform 30 can easily disassemble and install the transfer head 6, and also plays a certain limiting role to make the displacement of the transfer head 6 more stable and prevent it from shaking. It can also make the transfer head 6 quickly positioned and installed, thereby improving the efficiency of disassembly and installation, in order to deal with the situation where the transfer head 6 is damaged and needs to be replaced. At the same time, in order to protect the transfer head 6, a movable protective cover 35 can be provided at the opening 11, and it can be moved during use by means of a hinge.

[0065] It should be noted that the movable part 3 in this embodiment can also adopt an integrated connection structure or a split connection structure. Specifically, it will adopt an upper and lower split connection structure. The upper and lower movable parts 3 can be fixed by any of the following methods, including but not limited to buckle fixing, screw fixing, insertion fixing, ultrasonic heat fusion fixing, pivot hole fixing, and hinge fixing.

[0066] Please see Figure 9 , 10 As shown, the abutting member 2 in this embodiment is the same as in embodiment 1. It also has a first elastic part 21 and a second elastic part 22 that generate different elastic force changes according to different abutting forces. The first elastic part 21 and the second elastic part 22 abut against the movable part 3 and the winding reel 43 respectively. When the transfer head 6 is pressed and the movable part 3 is moved synchronously (transfer tool in use state), the movable part 3 that abuts against the first elastic part 21 will gradually abut against and squeeze it (the first elastic part 21). After being abutted and squeezed, the first elastic part 21 will be in an elastic energy storage state. At this time, the second elastic part 22 will be in an elastic energy release state because of the relative displacement of the movable part 3, which causes the squeezing force of the winding reel 43 on the second elastic part 22 to gradually decrease. This setting provides a progressive operating experience for the user's tape transfer operation, and the tape drawing is smoother. By changing the pressure applied by the user, the tape force is automatically adjusted under the action of each component, thereby achieving a relatively balanced tape drawing force before and after use.

[0067] Please see Figure 9 , 10 As shown, the movable member 3 is fixedly provided with a fitting member 7 that cooperates with the stop of the first elastic part 21. The fitting member 7 extends and protrudes towards the housing 1 and abuts against the outer side of the first elastic part 21. It is used to control the elastic force generated by the first elastic part 21 in the displacement direction of the movable member 3 relative to the housing 1. That is, when the movable member 3 is displaced relative to the housing 1 (when using a transfer tool for transfer or after the transfer is completed), the fitting member 7 abuts against and squeezes the outer side of the first elastic part 21 and causes it to be compressed to generate elastic energy storage or elastic energy release. The second elastic part 22 is configured in the same way as in Embodiment 1, with one end connected to the abutment member 2 and the other end abutting the winding reel 43. The second elastic part 22 resists the elastic force generated in the displacement direction of the movable member 3 relative to the housing 1, so as to control the friction force generated by the rotation of the winding reel 43. The principle is the same as in Embodiment 1, so it will not be described in detail. The effect of the transfer tool during transfer is similar to that in Embodiment 1. Similarly, after the transfer tool is used or not used, the second elastic part 22 will provide the winding reel 43 with a maximum elastic force, so that the friction force (braking force) reaches the maximum, thereby ensuring that the winding reel 43 and the winding wheel 41 will not be easily rotated. After the coating transfer tool is applied, under the action of this component, it can automatically lock the transmission component 4, thereby achieving the effect of "ready to use and ready to lift" and smooth coating at the beginning and end of the coating.

[0068] Please see Figures 9-12 , Figure 16 As shown, the first elastic part 21 and the second elastic part 22 in this embodiment are the same as in embodiment 1. However, as a preferred embodiment, a plurality of mating holes 34 corresponding to the second elastic part 22 are provided on the movable member 3. The mating holes 34 allow one end of the second elastic part 22 to pass through and abut against the transmission component 4. Therefore, a plurality of mating holes 34 corresponding to the elastic arm 221 are provided on the movable member 3. The mating holes 34 allow one end of the elastic arm 221 to pass through and abut against the inner wall of the winding disc 43. In this embodiment, the second elastic part 22 is specifically provided with two elastic arms 221 arranged in a front-to-back manner. The ends of the two elastic arms 221 abut against the inner wall of the winding disc 43. In this embodiment, the elastic arms 221 extend toward the winding disc 43, and their ends bend toward the inner wall of the winding disc 43 and abut against it.

[0069] It should be noted that the abutting member 2 in this embodiment is not only different from that in Embodiment 1 (the abutting member 2 moves synchronously with the transfer head 6), but its orientation is also opposite to that in Embodiment 1. Its first elastic part 21 extends towards the rear side of the housing 1. The two elastic arms 221 arranged one in front of the other are initially positioned such that the front elastic arm 221 abuts against and presses the inner wall of the winding reel 43, putting it in a frictional pre-tightened state with stored elastic energy, while the rear elastic arm 221 is not abutting against the inner wall of the winding reel 43 and is in a static state. When the movable member 3 moves relative to the housing 1 towards the rear, the elastic arm 221 located on the front side gradually... The device returns to its original state and is in an elastic release state. The elastic arm 221 located on the rear side gradually moves towards the inner wall of the winding reel 43 until it abuts against the inner wall. At this time, the elastic arm 221 on the rear side can also provide a resisting force for the winding reel 43. Even if the user makes an operational error and applies too much force, causing the elastic arm 221 on the front side to detach from the inner wall of the winding reel 43, the elastic arm 221 on the rear side will still provide frictional force. This further prevents the difference in frictional force between the front and rear sides caused by operational errors from being too large, thereby improving the coating effect of the transfer tool. Similar to Embodiment 1, the elastic arm 221 located on the rear side can also be omitted in this embodiment.

[0070] Please see Figure 9 , 10 As shown in Figure 16, a positioning part is provided between the housing 1 and the abutment 2, which includes a positioning groove 108 provided on either the housing 1 or the abutment 2, and a positioning block 109 provided on the other, which is matched with the positioning groove 108. In a preferred embodiment, the positioning groove 108 is provided on the abutment 2, and the positioning block 109 is provided on the housing 1. The positioning block 109 and the positioning groove 108 are engaged by a snap-fit, and the abutment 2 is fixed to the housing 1 by the snap-fit ​​between the positioning block 109 and the positioning groove 108.

[0071] Please see Figure 1 , 2 As shown in Figures 3 and 4, in order to ensure that the movable part 3 can move relative to the housing 1, a guide part is also provided between the housing 1 and the movable part 3. The movable part 3 can move relative to the housing 1 through the guide part. The guide part includes a guide groove 101 provided on either the housing 1 or the movable part 3, and a guide strip 102 provided on the other and slidingly engaged with the guide groove 101. As a preferred embodiment, the guide groove 101 is specifically provided on the housing 1. The guide groove 101 is composed of a limiting protrusion extending towards the movable part 3. The movable part 3 is provided with a guide strip 102 that slides with it. Through the guide groove 101 and the guide strip 102, the movable part 3 can move relative to the housing 1 in a certain range towards the front and rear sides.

[0072] Please see Figure 9-12As shown, in order to limit the displacement of the movable part within a certain range, a limiting part is also provided between the housing 1 and the movable part 3. The movable part 3 can control the displacement distance relative to the housing 1 through the limiting part. It includes a first limiting part 103 provided on either the housing 1 or the movable part 3, and a second limiting part 104 provided on the other to limit and cooperate with the first limiting part 103. It should be noted that in this embodiment, the second limiting part 104 is defined within the vertical projection range of the first limiting part 103. When the movable part 3 moves relative to the housing 1, the second limiting part 104 moves within the vertical projection range of the first limiting part 103. As a preferred embodiment, the first limiting part 103 in this embodiment is specifically a limiting frame provided on the housing 1, and the second limiting part 104 is a limiting protrusion provided on the movable part 3. The limiting protrusion extends and protrudes towards the limiting frame and abuts against the inner side of the limiting frame, thereby limiting the displacement of the movable part 3 through the limiting frame.

[0073] In a preferred embodiment, the displacement distance between the movable part 3 and the housing 1 is also preferably 0.05~0.35mm.

[0074] Please see Figure 9 , 10 As shown in Figures 13 and 15, in order to ensure the transmission between the transmission components, the movable part 3 is provided with several guide posts 31. The winding wheel 41 and the recovery wheel 42 are respectively rotatably mounted on the several guide posts 31. In order for the winding wheel 41 and the recovery wheel 42 to be connected by transmission, a transmission wheel 44 is also provided between the winding wheel 41 and the recovery wheel 42. The winding wheel 41, the recovery wheel 42 and the transmission wheel 44 are connected by a gear structure. The transmission method between the transmission components 4 is similar to the prior art, so it will not be described in detail here. At the same time, setting the transmission components 4 on the movable part 3 can also protect the transmission components 4 and prevent them from being damaged.

[0075] Example 3 Please see Figure 1 , 8As shown, as another core advantage of the present invention, the coating transfer tool of the present invention also includes an anti-rotation part. This anti-rotation part can further prevent the transfer tool from being affected by vibration during transportation and carrying. The anti-rotation part includes an elastic element 105 with elastic restoring force disposed on either the housing 1 or the movable part 3, and an movable hole 107 providing space for the elastic deformation of the elastic element 105. The end of the elastic element 105 engages unidirectionally with the gear structure of the recovery wheel 42. That is to say, this anti-rotation part can be applied to the coating transfer tool of either Embodiment 1 or Embodiment 2. Specifically, in this embodiment, the anti-rotation part is applied to the coating transfer tool structure in Embodiment 1. As a preferred embodiment, this embodiment specifically applies the anti-rotation part to the housing... The body 1 is provided with an elastic element 105 with specific elastic restoring force and a movable hole 107 for the elastic deformation space of the elastic element 105. In a preferred embodiment, an opening space for accommodating mechanical parts or fingers can also be correspondingly provided on the housing 1 (at the anti-rotation part). The user can use a mechanical part (not shown in the figure) to push the elastic element 105 away from the take-up wheel 42, or manually push the elastic element 105 with their fingers to make it elastically deform within the movable hole 107 until the elastic element 105 disengages from the take-up wheel 42, releasing the one-way engagement state, so that the transfer instrument can achieve a relatively quiet effect and avoid noise interference. This embodiment adopts the manual pushing scheme. Please refer to [link to relevant documentation]. Figure 8 As shown, the end of the elastic element 105 is specifically provided with a ratchet that meshes unidirectionally with the gear structure of the recycling wheel 42. The unidirectional meshing can ensure that the recycling wheel 42 is not easily rotated, and together with the second elastic part 22, it provides a double guarantee for the transmission assembly 4 in the state of the transfer tool when it is not in use or after use. In particular, it can effectively lock the transmission mechanism during carrying and transportation, so as to keep the core of the coating transfer tool flat and not scattered. Example 4 Please see Figure 12 , 13As shown in Figure 15, as another preferred embodiment of the present invention, the coating transfer tool structure of this embodiment is the same as that of Embodiment 2, and therefore will not be described again. However, this embodiment also provides an anti-rotation part between the housing 1 and the movable part 3. The anti-rotation part is provided on the movable part 3. The anti-rotation part can further prevent the vibration of the transfer tool during transportation and carrying. Specifically, this embodiment provides an elastic element 105 with specific elastic restoring force and an active hole 107 for the elastic deformation space of the elastic element 105 on the movable part 3. The positioning part 106 that cooperates with the stop of the elastic element 105 is... The elastic element 105 is correspondingly disposed on the housing 1, specifically, the elastic element 105 is correspondingly disposed in the movable hole 107, and the positioning element 106 is correspondingly disposed on the housing 1. When the user uses the transfer tool to perform a strip transfer operation and applies pressure to the transfer head to synchronously drive the movable element 3 to move towards the rear side relative to the housing 1, the positioning element 106 will abut against and push the elastic element 105, causing the elastic element 105 to elastically deform within the movable hole 107 until the elastic element 105 disengages from the recovery wheel 42, releasing the one-way engagement state, so that the transfer tool can achieve a relatively quiet effect and avoid noise disturbance.

[0076] Example 5 This embodiment also provides a coating transfer tool, wherein the main structure of the transfer tool in this embodiment is basically the same as that in embodiment 2, and adopts the anti-rotation part in embodiment 4. However, the abutment 2 in this embodiment is slightly different. In this embodiment, the abutment 2 and the mating part mainly adopt a magnetic attraction scheme, so that the mating part 7 and the abutment 2 generate a like-pole mutual repulsion reaction, thereby causing the transfer head 6 to reset, replacing the elastic deformation reset scheme in embodiments 1-4. Specifically: Please see Figure 17 As shown, the abutting member 2 has a second elastic part 22 that generates different elastic force changes according to different abutting forces and a magnetic attraction part 23 that is magnetically connected to the mating member 7; the second elastic part 22 abuts against the transmission assembly 4, and the magnetic attraction part 23 and the mating member 7 maintain a state of magnetic attraction or magnetic repulsion, and in this embodiment, the state of magnetic repulsion is preferred.

[0077] When the transfer head 6 moves from the first position to the second position relative to the housing 1, the magnetic attraction part 23 and the mating part 7 are attracted or repelled by magnetism, so that the second elastic part 22 is in an elastic energy storage or elastic energy release state. In a preferred embodiment, the magnetic attraction part 23 and the mating part 7 are made of magnets with the same pole to maintain magnetic repulsion.

[0078] It should be noted that the second elastic part 22 in this embodiment is also always in contact with the transmission component 4.

[0079] Example 6 Please see Figure 18As shown, as another preferred embodiment, the coating transfer tool structure and operating principle provided in this embodiment are the same as in Embodiment 2, so they will not be described in detail. However, in this embodiment, the abutment 2 and the housing 1 are integrated, that is, the abutment 2 can be a component located at any position on / inside the housing 1. Specifically: In this embodiment, the second elastic part 22 of the abutment member 2 is integrally formed with the guide post 31, and also has an end extending towards the inner wall of the winding reel 43 for abutment. During manufacturing, the second elastic part 22 is in an abutment pre-tightened state (elastic energy storage state), while the first elastic part 21 is provided on the housing 1, and the mating part that cooperates with it is also provided on the movable part 3, so that the transfer head 6 can return to its original position on the movable part 3. On the inner wall of the housing 1 facing the second elastic part 22, a stop block 12 is also provided. The stop block 12 is used to abut and push the second elastic part 22 when the transfer head 6 synchronously drives the movable part 3 to move between the first position and the second position. As part 22 gradually reduces the pre-tightening force against the inner wall of the winding reel 43, similar to embodiments 1 and 2, the second elastic part 22 always remains in contact with the winding reel 43 when the transfer head 6 moves between the first and second positions. That is, even when the transfer head 6 is at a certain maximum second position, the second elastic part 22 is not completely disengaged from the winding reel 43. It should be noted that the integrated abutment part 2 solution can also be used in embodiment 1. By simplifying the components, it not only has the advantages of the above embodiments, but also reduces production steps, improves production efficiency, controls costs, and allows consumers to avoid worrying about the replacement of damaged independent components.

[0080] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0081] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
