Description

Technical Field

[0001] This application relates to the field of tape applicator technology, and in particular to a tape applicator with dual-track reset. Background Technology

[0002] In daily life, adhesive materials such as masking tape, duct tape, and double-sided tape are widely used in home decoration, DIY crafts, and packaging. To facilitate the application of these adhesive materials with a straight path and a complete cut, users often use tape applicators that can cut the tape and have a vertical shell.

[0003] Among them, this type of tape applicator includes a tape applicator with a bidirectional blade head. The blade holder is slidably installed inside the housing. The movement of the blade holder is driven by a push block, and the reset of the blade holder and the push block is completed by a single spring. This can cause jamming when using a spring with poor rebound force or a spring that has been used for a long time, requiring the user to manually push the push block to assist in the reset. This manual reset may cause the tape to shift. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a dual-track reset tape applicator to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a dual-track reset adhesive tape applicator, comprising: a first housing, a second housing, and a push block. The first housing and the second housing are spliced ​​together. The push block is disposed on the first housing and can be displaced. A first elastic element is provided on the first housing for driving the push block to reset. Two first sliding grooves are provided on the lower part of the first housing. The push block is provided with a first sliding buckle that can slide within the first sliding grooves. A movable blade holder is provided between the first housing and the second housing. The movable blade holder includes a first blade holder, a second blade holder, and a second elastic element. Each of the first and second tool holders has a blade at its outer end. The elastic element is used to drive the inner ends of the first and second tool holders to come close to each other. Both the first and second tool holders have a sliding block that can slide in the first groove on the side near the first housing. The distance between the two sliding blocks is greater than the distance between the two first sliding buckles. The push block can drive the first or second tool holder to move in the direction of the blade. The inner side of the first or second housing is provided with a limiting part. The limiting part can be engaged between the first and second tool holders to prevent the first and second tool holders from being driven by the push block at the same time.

[0007] In some embodiments, two spring push pins are provided on one side of the push block to abut against both sides of the first elastic element, and grooves are provided on both sides of the spring mounting base to allow the spring push pins to pass through.

[0008] In some embodiments, a support is provided on one side of the second housing.

[0009] In some embodiments, a second sliding buckle is further provided at the center position below the push block, and a second sliding groove is provided between the first sliding grooves to cooperate with the second sliding buckle.

[0010] In some embodiments, a limiting groove is provided at one end of the first tool post and the second tool post that abuts against each other, and the limiting grooves of the first tool post and the second tool post can be combined to form a limiting groove corresponding to the size of the limiting part.

[0011] In some embodiments, the ends of the first and second tool holders that abut against each other have a sliding locking portion. Two hook portions are formed on the end of the sliding locking portion. The second tool holder has a tool holder groove that allows the sliding locking portion to slide. The hook portions can be engaged with the inner wall of the tool holder groove.

[0012] In some embodiments, the second elastic element is a tension spring, and a spring groove is provided on the sliding locking part. One end of the second elastic element is connected to the bottom of the spring groove, and the other end is connected to the bottom of the tool holder groove.

[0013] In some embodiments, pressure plates are rotatably provided on both sides of the first housing and the second housing, and an abutment block that can cooperate with the end of the pressure plate is also provided between the first housing and the second housing.

[0014] In some embodiments, the pressure plate is made of a metal material that can be magnetically attracted, and the abutment block is made of a magnet.

[0015] The beneficial effects of this application are as follows: the limiting part enables only the first tool post or the second tool post to slide when the slider is pushed. At the same time, the second elastic element between the first tool post and the second tool post can assist the first elastic element in resetting the push block. The second elastic element shares the pressure on the first elastic element, ensuring that the push block can still maintain a good state of reset after long-term use. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0026] In the embodiments of this application, please refer to Figure 1-7As shown, this application provides a dual-track reset adhesive tape applicator, mainly comprising: a first housing 1 and a second housing 2 spliced ​​together; a pusher block 3 disposed on the first housing 1 and capable of displacement; a first elastic element 111 disposed on the first housing 1 for driving the pusher block 3 to reset; two first sliding grooves 12 formed below the first housing 1; and a first sliding buckle 31 disposed on the pusher block 3 capable of sliding within the first sliding grooves 12; a movable blade holder 4 disposed between the first housing 1 and the second housing 2; the movable blade holder 4 includes a first blade holder 41, a second blade holder 42, and a second elastic element 44; and each of the first blade holder 41 and the second blade holder 42 is provided with a blade 43 at its outer end. The second elastic element 44 is used to drive the inner ends of the first tool holder 41 and the second tool holder 42 to come close to each other. The first tool holder 41 and the second tool holder 42 are each provided with a sliding block 411 that can slide in the first sliding groove 12 on the side near the first housing 1. The distance between the two sliding blocks 411 is greater than the distance between the two first sliding buckles 31. The push block 3 can move in the direction of the blade by driving the first tool holder 41 or the second tool holder 42. The inner side of the first housing 1 or the second housing 2 is provided with a limiting part 21. The limiting part 21 can be engaged between the first tool holder 41 and the second tool holder 42 to prevent the first tool holder 41 and the second tool holder 42 from being driven by the push block 3 at the same time.

[0027] Specifically, when the user pushes the push block 3, the first sliding buckle 31 on the push block 3 will slide in the first sliding groove 12. At the same time, the distance between the two sliding blocks 411 is greater than the distance between the two first sliding buckles 31. Therefore, the first sliding buckle 31 can only drive one of the sliding blocks 411 to move. In order to prevent the first tool holder 41 and the second tool holder 42 from being pushed by the sliding block 411 at the same time under the connection of the second elastic element 44, the existence of the limiting part 21 allows the limiting part 21 to restrict the other tool holder when the first tool holder 41 or the second tool holder 42 moves, so that the push of the push block 3 can synchronously make the first elastic element 111 and the second elastic element 44 be subjected to pressure synchronously, and can provide excellent rebound force.

[0028] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0029] Reference Figure 7 As shown, the first elastic element 111 is a compression spring, and a spring mounting seat 11 is provided on the first housing 1. The first elastic element is disposed in the spring mounting seat 11. Two spring push pins 33 are provided on one side of the push block 3 and abut against both sides of the first elastic element 111. Grooves 112 are provided on both sides of the spring mounting seat 11 to allow the spring push pins 33 to pass through.

[0030] Reference Figure 7 As shown, in order to enable the tape applicator to support some vertical support surfaces during use, a backrest 5 is provided on one side of the second housing 2.

[0031] Reference Figure 2 As shown, a second sliding buckle 32 is also provided at the center position below the push block 3. A second sliding groove 13 is provided between the first sliding groove 12 to cooperate with the second sliding buckle 32. The second sliding buckle 32 can assist the first sliding buckle 31 to better install the push block 3 on one side of the first housing 1, so that the pressure can be evenly distributed when it is disassembled, and to prevent the push block 3 from undergoing plastic deformation during disassembly.

[0032] Specifically, a limiting groove 412 is provided on one side of the end where the first tool post 41 and the second tool post 42 abut against each other. The limiting grooves 412 of the first tool post 41 and the second tool post 42 can be combined to form a limiting groove 412 that corresponds to the size of the limiting part 21. This setting allows the limiting part 21 to intervene between the first tool post 41 and the second tool post 42 when they are not unfolded, ensuring that only the first tool post 41 or the second tool post 42 can move.

[0033] Reference Figure 5-6 As shown, in order to make the connection between the first tool holder 41 and the second tool holder 42 more stable, a sliding locking part 413 extends from the end of the first tool holder 41 and the second tool holder 42 that abuts against each other. Two hooks 4131 are formed on the end of the sliding locking part 413. The second tool holder 42 is provided with a tool holder groove 421 that allows the sliding locking part 413 to slide. The hooks 4131 can be engaged with the inner wall of the tool holder groove 421.

[0034] Specifically, the second elastic element 44 is a tension spring, and the sliding locking part 413 is provided with a spring groove 4132. One end of the second elastic element 44 is connected to the bottom of the spring groove 4132, and the other end is connected to the bottom of the tool holder groove 421. With this arrangement, the second elastic element 44 will not occupy additional space, reducing the volume occupied by the floating tool holder 4.

[0035] In one embodiment, the second elastic element 44 can also be a compression spring. The second elastic element can abut against both ends of the first tool holder 41 and the second tool holder 42. When either the first tool holder 41 or the second tool holder 42 is subjected to a pushing force, the second elastic element 44 located at this end is compressed by pressure and can be driven to reset.

[0036] Specifically, pressure plates 6 are rotatably arranged on both sides of the first housing 1 and the second housing 2. An abutment block 7 is also provided between the first housing 1 and the second housing 2, which can cooperate with the end of the pressure plate 6 to abut. Specifically, the cooperation between the pressure plate 6 and the abutment block 7 can press down the tape at both ends. The implementation process is as follows: The user pulls out the tape from one end and pulls it from the bottom to the pressure plate 6 at the other end. The pressure plate 6 locks the end of the tape and cuts it with the blade 43 at this end. This can prevent the tape end from having poor adhesion due to pulling out the tape and ensure a smooth end face. Then the tape can be pasted. After pasting is completed, the pressure plate 6 in the tape exit direction is locked and cut with the blade 43.

[0037] Preferably, the pressure plate 6 is made of a metal material that can be magnetically attracted, the abutment block 7 is made of a magnet, and the rotation shaft of the pressure plate 6 can also be a damped shaft to ensure the abutment strength between the pressure plate 6 and the abutment block 7.
