Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery, and in particular to a yarn breakage alarm device with a storage function. Background Technology

[0002] The yarn feeder is an important component of a knitting machine. It mainly consists of a housing, a main shaft mounted on it, and a yarn storage cylinder. A pressure ring and a tension coil are fitted onto the yarn storage cylinder. The main shaft is located at the center of the yarn storage cylinder and drives its rotation to store yarn. Yarn storage involves feeding the yarn into the cylinder and storing it there; yarn feeding involves the yarn being output from the cylinder via the tension coil. Existing yarn storage devices are equipped with yarn breakage alarm devices. For example, a yarn storage device that facilitates yarn feeding is disclosed in Chinese Patent (Authorization Announcement No. CN222100290U). The yarn storage device body has a yarn breakage alarm mechanism at the yarn inlet end. The yarn breakage alarm mechanism includes a trigger unit and a yarn feeding swing rod that is pivotally connected to the side of the trigger unit. The yarn storage device body has a circuit board and an alarm light. The trigger unit and the alarm light are electrically connected to the circuit board. A U-shaped tube is provided on the side of the yarn feeding swing rod away from the pivot end. A yarn guide is clamped on the U-shaped tube. When a yarn breakage occurs, the supporting force of the yarn on the yarn feeding swing rod disappears, causing the yarn feeding swing rod to swing downward and trigger the trigger unit, so that the circuit board controls the yarn storage device body to stop.

[0003] The existing yarn feeding lever extends out of the machine body in both the working and non-working states of the yarn storage device. Due to its slender structure, it is easily bent. At the same time, in the non-working state, the yarn feeding lever is in a yarn breakage state due to the lack of yarn support and continuously triggers the alarm in conjunction with the triggering unit. Therefore, it needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a yarn breakage alarm device with a storage function. The yarn breakage detection component can be moved to the storage position when the yarn storage device is not in operation. On the one hand, this can prevent it from continuously triggering the alarm by cooperating with the conductive spring, and on the other hand, it can prevent it from being accidentally bent.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn breakage alarm device with a storage function, the yarn breakage alarm device being used in a yarn storage device, the yarn storage device including a machine body, and the yarn breakage alarm device including... The electronic control module is fixedly installed inside the machine body; An alarm is installed inside the unit and electrically connected to the electronic control module. The conductive spring pair includes a first conductive spring and a second guide spring. The first conductive spring and the second guide spring each have a free end and a connecting end. The connecting end is fixedly connected to the machine body and electrically connected to the electronic control module through a wire. The yarn breakage detection component can slide between an extended position extending out of the machine body and a retracted position moved up into the machine body. The yarn breakage detection component is a conductive metal component. The machine body is provided with a positioning structure for positioning the yarn breakage detection component in the retracted position. The lower end of the yarn breakage detection component is provided with a concave arc-shaped part for guiding the yarn. In the working state, the yarn breakage detection component is supported by the yarn below, so that the yarn breakage detection component is in the area between the extended position and the retracted position. When a yarn breakage occurs, the yarn breakage detection component moves to the extended position under the action of gravity and presses against the free ends of the first conductive spring and the second guide spring, so that the electronic control module, the first conductive spring and the second guide spring are connected through the yarn breakage detection component, at which time the alarm is triggered. In the non-working state, the yarn breakage detection component can be moved to the retracted position and is held in the retracted position by the positioning structure.

[0006] Furthermore, the yarn breakage detection component has a frame-shaped structure.

[0007] Furthermore, the machine body is provided with a vertically or inclined guide groove, and the yarn breakage detection component is slidably installed in the guide groove and can slide along the guide groove.

[0008] Furthermore, the upper end of the yarn breakage detection component is housed within the machine body, and a limiting part is provided within the machine body to prevent the yarn breakage detection component from falling out of the machine body.

[0009] Furthermore, the positioning structure includes a protrusion or elastic positioning part protruding from the upper part of the guide groove. In the non-working state, the yarn breakage detection component is pressed up so that its upper end squeezes past the protrusion or elastic positioning part. At this time, the yarn breakage alarm component is limited to the storage position by the protrusion or elastic positioning part. When it is needed to work, the yarn breakage detection component is pulled down so that its upper end squeezes past the protrusion or elastic positioning part. At this time, the yarn breakage alarm component moves to the extended position under its own gravity.

[0010] Furthermore, the positioning structure includes a positioning component movably disposed on the upper part of the corresponding guide groove of the machine body. The positioning component can move laterally between the positioning position and the unlocking position. In the non-working state, the yarn breakage detection component is moved up to the storage position, and then the positioning component is driven to the positioning position. The positioning component limits the yarn breakage detection component to the storage position. When it is needed to work, the positioning component is first driven to the unlocking position. At this time, the yarn breakage detection component moves to the extension position under its own gravity.

[0011] Furthermore, the positioning structure is a magnetic block set on the upper part of the guide groove, and the yarn breakage detection component is a metal part that can magnetically engage with the magnetic block. In the non-working state, the yarn breakage detection component is pressed up to move it to the storage position, and is attracted to the storage position by the magnetic block. When it is needed to work, the yarn breakage detection component is pulled down to disengage it from the magnetic block. At this time, the yarn breakage alarm component can move to the extended position.

[0012] Furthermore, the machine body is provided with a fixed seat, which is provided with a fixed position for installing the connecting end of the first conductive spring and the second guide spring, and a support position corresponding to the lower end of the first conductive spring and the second guide spring. When the yarn breakage detection device is in the extended position, the yarn breakage detection device presses the free ends of the first conductive spring and the second guide spring into the support position, and connects the first conductive spring, the second guide spring and the electronic control module through the yarn breakage detection device.

[0013] Furthermore, the first conductive spring and the second guide spring are made of copper, and a magnetic block is provided on the support position. When the yarn breakage detection component moves to the extended position under the action of gravity, the yarn breakage detection component and the magnetic block magnetically cooperate, so that the free ends of the first conductive spring and the second guide spring are firmly pressed onto the support position by the yarn breakage detection component.

[0014] In summary, this utility model has the following beneficial effects: The yarn breakage alarm device of this utility model allows the yarn breakage detection component to be moved to a storage position when the yarn storage device is not in operation. This prevents it from continuously triggering the alarm by engaging with the conductive spring and also prevents it from being accidentally bent. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figures 1-5 As shown, a yarn breakage alarm device with a storage function is used in a yarn storage device. The yarn storage device includes a body 10, a yarn storage cylinder rotatably connected to the body 10, and a motor that drives the yarn storage cylinder to rotate.

[0025] The yarn breakage alarm device includes an electronic control module, an alarm, a pair of conductive springs 20, and a yarn breakage detection element 30. The electronic control module is fixedly installed inside the machine body 10. The alarm is located inside the machine body 10 and electrically connected to the electronic control module. The alarm includes, but is not limited to, an alarm light, a buzzer, and a horn. The pair of conductive springs 20 includes a first conductive spring 21 and a second guide spring 22. The first conductive spring 21 and the second guide spring 22 include a free end 23 and a connecting end 24. The connecting end 24 is fixedly connected to the machine body 10 and electrically connected to the electronic control module through a wire. The yarn breakage detection component 30 can slide between an extended position extending out of the machine body 10 and a retracted position moved up into the machine body 10. The yarn breakage detection component 30 is a conductive metal component. A positioning structure 40 is provided inside the machine body 10 to position the yarn breakage detection component 30 in the retracted position. Specifically, when the yarn breakage detection component 30 is in the retracted position, most of its area is located inside the machine body 10, with only a small portion of its lower end extending outside the area. This is to facilitate the user to pull down the yarn breakage detection component 30 through the portion extending outside the machine body 10 for subsequent work.

[0026] In the working state, the yarn breakage detection element 30 is supported by the yarn below, so that the yarn breakage detection element 30 is in the area between the extended position and the retracted position. When a yarn breakage occurs, the yarn breakage detection element 30 moves to the extended position under the action of gravity and presses against the free end 23 of the first conductive spring 21 and the second guide spring 22, so that the electronic control module, the first conductive spring 21 and the second guide spring 22 are connected through the yarn breakage detection element 30, and the alarm is triggered at this time. In the non-working state, the yarn breakage detection element 30 can be moved to the retracted position and is held in the retracted position by the positioning structure 40.

[0027] In this utility model, the yarn breakage alarm device has a yarn breakage detection component 30 that can be moved to a storage position when the yarn storage device is not in operation. This prevents it from continuously triggering the alarm in conjunction with the conductive spring pair 20 and also prevents it from being accidentally bent.

[0028] In some embodiments, the yarn breakage detection element 30 is a frame-shaped structure with a breakage area 31. The breakage area 31 is outside the area corresponding to the free end 23 of the first conductive spring 21 and the second guide spring 22. The purpose of designing the yarn breakage detection element 30 as a frame-shaped structure is to facilitate processing. The lower end of the yarn breakage detection element 30 is provided with a concave arc-shaped part 32, which guides the yarn.

[0029] In some embodiments, the machine body 10 is provided with a vertically or inclined guide groove 11, and the yarn breakage detection element 30 is slidably installed in the guide groove 11 and can slide along the guide groove 11. Preferably, guide frames are provided on both sides of the machine head, and a vertically arranged guide groove 11 is formed in the guide frame. The guide frame limits and guides the yarn breakage detection element 30.

[0030] In some embodiments, the upper end of the yarn breakage detection element 30 is housed within the machine body 10, and the machine body 10 is provided with a limiting part to prevent the yarn breakage detection element 30 from falling out of the machine body 10. The limiting part restricts the yarn breakage detection element 30 from detaching from the machine body 10 when there is no yarn support.

[0031] In some embodiments, the positioning structure 40 includes a protrusion 41 or an elastic positioning part protruding from the upper part of the guide groove 11. In the non-working state, the yarn breakage detection member 30 is pressed up so that its upper end squeezes past the protrusion 41 or the elastic positioning part. At this time, the yarn breakage alarm member is limited to the storage position by the protrusion 41 or the elastic positioning part. When it is needed to work, the yarn breakage detection member 30 is pulled down so that its upper end squeezes past the protrusion 41 or the elastic positioning part. At this time, the yarn breakage alarm member moves to the extended position under its own gravity. Preferably, the body 10 is provided with protrusion 41 or elastic positioning part on both sides corresponding to the yarn breakage detection member 30. In this utility model, the protrusion 41 is preferred. The protrusion 41 is a semi-circular protrusion 41.

[0032] In some embodiments, the positioning structure 40 includes a positioning member movably disposed on the upper part of the guide groove 11 corresponding to the machine body 10. The positioning member can move laterally between the positioning position and the unlocking position. In the non-working state, the yarn breakage detection member 30 is moved upward to the storage position, and then the positioning member is driven to the positioning position. The positioning member limits the yarn breakage detection member 30 to the storage position. When working, the positioning member is first driven to the unlocking position. At this time, the yarn breakage detection member 30 moves to the extended position under its own gravity. The positioning member can be, for example, a crossbar that can be telescopically disposed on the machine body 10, or a threaded rod that is threaded to the machine head.

[0033] In some embodiments, the positioning structure 40 is a magnetic block disposed on the upper part of the guide groove 11, and the yarn breakage detection component 30 is a metal part that can magnetically engage with the magnetic block. In the non-working state, the yarn breakage detection component 30 is pressed up to move it to the storage position and is attracted to the storage position by the magnetic block. When it is needed to work, the yarn breakage detection component 30 is pulled down to disengage it from the magnetic block. At this time, the yarn breakage alarm component can move to the extended position.

[0034] In some embodiments, a fixing seat 50 is provided inside the body 10. The fixing seat 50 is provided with a fixing position 51 for mounting the connecting end 24 of the first conductive spring 21 and the second guide spring 22, and a support position 52 correspondingly provided at the lower end of the first conductive spring 21 and the second guide spring 22. When the yarn breakage detection element 30 is in the extended position, the yarn breakage detection element 30 presses the free ends 23 of the first conductive spring 21 and the second guide spring 22 into the support position 52, and connects the first conductive spring 21 and the second guide spring 22 to the electronic control module through the yarn breakage detection element 30. In the initial state, the support position 52 can be configured to contact the free ends 23 of the first conductive spring 21 and the second guide spring 22, or configured to be spaced apart from the free ends 23 of the first conductive spring 21 and the second guide spring 22. The height of this spaced area is small to avoid excessive downward pressure on the first conductive spring 21 and the second guide spring 22, which would affect their service life.

[0035] In some embodiments, the first conductive spring 21 and the second guide spring 22 are made of copper, and a magnetic block is provided on the support position 52. When the yarn breakage detection element 30 moves to the extended position under the action of gravity, the yarn breakage detection element 30 magnetically engages with the magnetic block, so that the free ends of the first conductive spring 21 and the second guide spring 22 are firmly pressed onto the support position 52 by the yarn breakage detection element 30, thereby making the first conductive spring 21, the second guide spring 22 and the electronic control module firmly connected through the yarn breakage detection element 30. In addition, since copper does not attract the magnetic block, when the yarn breakage detection element 30 is pushed upward, the free ends of the first conductive spring 21 and the second guide spring 22 are reset under their own elastic force.

[0036] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
