Description

Technical Field

[0001] This utility model relates to the technical field of doubling machines, and in particular to a doubling machine that is easy to replace yarn bobbins. Background Technology

[0002] In the textile industry, the doubling machine is a key piece of equipment used to twist yarn. It achieves yarn twisting through high-speed rotation to improve yarn strength and luster. When the doubling machine is working, it needs to continuously consume the yarn on the yarn bobbin. When the yarn is used up, a new yarn bobbin needs to be replaced in time to ensure production continuity. Therefore, a doubling machine that is easy to replace the yarn bobbin is particularly needed.

[0003] The yarn bobbin of a traditional twisting machine is often installed in a concealed location, requiring operators to bend over or reach into the machine to operate it. Long-term operation can easily lead to fatigue. During manual unlocking, improper operation may cause the yarn bobbin to slip or collide with equipment parts, posing a safety hazard. Relying on manual judgment to determine whether the yarn is used up can easily lead to the machine running idle after the yarn is used up due to negligence.

[0004] To address the aforementioned issues, a doubling machine that facilitates yarn bobbin replacement is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a twisting machine that facilitates the replacement of yarn bobbins, so as to solve the problem of the existing twisting machines that facilitate the replacement of yarn bobbins mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a twisting machine that facilitates the replacement of yarn bobbins, comprising a twisting machine body, a base at the bottom of the twisting machine body, a sliding plate at the top of the base, springs on both sides of the top wall of the base, sliders on both sides of the top wall of the base, and the sliders connected to the springs, a locking block installed at one end of the base, and a limit block integrally formed on the top of the sliding plate.

[0007] Preferably, the top of the base has two sets of sliding grooves, the top of the base has a limiting groove, and the limiting groove is located between the sliding grooves. One end of the base has an installation groove, and a baffle is installed on the outer side of the top of the installation groove at one end of the base.

[0008] Preferably, the top of the slide plate has a slot, the inside of the slot has a round shaft, one end of the slot has a connecting arm integrally formed, both sides of the connecting arm have guide grooves, and a connecting post is slidably connected between the guide grooves.

[0009] Preferably, the twisting machine body further includes four sets of partitions at its bottom, and the partitions divide the bottom of the twisting machine body into five spaces, and a cylinder is installed on the top of the slide plate.

[0010] Preferably, both the spring and the slider are located inside the groove, with the end of the spring away from the slider connected to the end wall of the groove, and the top of the slider connected to the slide plate.

[0011] Preferably, the limiting block is slidably connected to the limiting groove.

[0012] Preferably, the card block engages with the card slot.

[0013] Preferably, the locking block is disposed in the mounting groove, and the locking block is rotatably connected to the base via a round shaft.

[0014] Preferably, the base and the slide plate are each provided in five sets, and are respectively located in the space formed by the partition.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This device uses sensors to detect when the yarn is depleted. When an empty yarn bobbin is detected, a miniature electric actuator can quickly drive the locking block to unlock. With the help of a spring, the sliding plate automatically pops out, exposing the empty yarn bobbin directly within the operating range. Operators can replace the yarn bobbin without having to go deep into the equipment, avoiding cumbersome actions such as bending over and reaching out. To reset, simply push the sliding plate back manually to automatically lock it. The device is easy to operate and reduces fatigue during long-term operation. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] like Figure 1-4 As shown, the device includes a twisting machine body 1, a base 2 at the bottom of the twisting machine body 1, a slide plate 3 at the top of the base 2, springs 4 on both sides of the top wall of the base 2, sliders 5 on both sides of the top wall of the base 2, and the sliders 5 are connected to the springs 4. A limiting block 7 is integrally formed on the top of the slide plate 3. Two sets of sliding grooves 8 are opened on the top of the base 2, and a limiting groove 9 is opened on the top of the base 2, with the limiting groove 9 located between the sliding grooves 8. The twisting machine body 1 also includes four sets of partitions 17 at its bottom, and the partitions 17 divide the bottom of the twisting machine body 1 into five spaces. A cylinder 18 is installed on the top of the slide plate 3.

[0026] It should be noted that in this embodiment, when the locking block 6 separates from the sliding plate 3, the spring 4 in the sliding groove 8 of the base 2 recovers its deformation and generates elastic force to push the slider 5 to slide along the sliding groove 8. The top of the slider 5 is connected to the sliding plate 3, so it drives the sliding plate 3 to move synchronously. When the sliding plate 3 moves, the limiting block 7 at the top slides along the limiting groove 9 of the base 2. The limiting block 7 and the limiting groove 9 cooperate to ensure that the sliding plate 3 pops out only in a straight line to avoid deviation. The sliding plate 3 drives the empty yarn tube body 18 on it to pop out to the outside of the base 2 until the sliding plate 3 partially extends out of the base 2. At this time, the empty yarn tube is completely exposed to the range that the operator can access, making it convenient for the operator to replace the yarn tube.

[0027] Furthermore, the device divides the bottom of the twisting machine into five independent spaces through the partition 17. Each space corresponds to a set of base 2, slide plate 3 and bobbin 18 structure, which can independently complete the replacement of yarn bobbins without interfering with each other, thus improving work efficiency.

[0028] The replacement of yarn bobbins is a mature technology in the existing field, and the specific replacement principle and process will not be described here.

[0029] like Figure 5 As shown, a locking block 6 is installed at one end of the base 2, an installation groove 10 is opened at one end of the base 2, a baffle 11 is installed on the outer side of the top of the installation groove 10 at one end of the base 2, a locking groove 12 is opened at the top of the sliding plate 3, a round shaft 13 is inserted inside the locking block 6, a connecting arm 14 is integrally formed at one end of the locking block 6, guide grooves 15 are opened on both sides of the connecting arm 14, and a connecting post 16 is slidably connected between the guide grooves 15.

[0030] It should be noted that in this embodiment, a set of sensors can be installed on the central rod of the bobbin 18. When the yarn on the bobbin 18 is gradually used up, the sensor on the central rod of the bobbin 18 senses the state of no yarn. After the control system recognizes the signal, it determines that the current bobbin needs to be replaced and then sends a start command to the micro electric actuator. The extended end of the micro electric actuator pushes the connecting column 16 to move. The connecting column 16 slides in the guide grooves 15 on both sides of the connecting arm 14. The locking block 6 and the connecting arm 14 are an integral structure. The thrust of the connecting column 16 drives the connecting arm 14 to rotate around the circular shaft 13. Therefore, the locking block 6 rotates synchronously around the circular shaft 13 in the mounting groove 10. During the rotation of the locking block 6, its engagement with the top locking groove 12 of the slide plate 3 is released. At this time, the fixed constraint of the slide plate 3 is removed.

[0031] Preferably, the sensor can be an infrared photoelectric sensor. When there is yarn on the yarn bobbin, the yarn blocks the light and the receiver has no signal. When the yarn is used up, the light is not blocked and the receiver triggers a signal. It is not affected by the color of the yarn. The control of the sensor and the micro electric actuator and its principle are existing mature technologies and will not be described here.

[0032] Furthermore, the baffle 11 is used to limit the height of the connecting arm 14 to prevent the connecting arm 14 from being too high and affecting the ejection of the slide plate 3.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-5 When the device is working normally, all components are locked. The slide plate 3 and the bobbin 18 carrying the yarn are connected by the locking block 6 and the locking groove 12 and are fixed on the base 2. The springs 4 in the sliding grooves 8 on both sides of the base 2 are compressed. The limiting block 7 at the top of the slide plate 3 is embedded in the limiting groove 9 of the base 2 to limit the lateral displacement of the slide plate 3 and ensure that it is stable in the independent space separated by the partition 17 at the bottom of the twisting machine body 1. The locking block 6 is rotatably connected to the mounting groove 10 of the base 2 through the round shaft 13. The connecting column 16 on the connecting arm 14 is connected to the extended end of the micro electric push rod. A yarn sensor is installed at the center rod of the bobbin 18 to monitor whether the yarn is used up in real time.

[0035] When the yarn on the bobbin 18 is gradually used up, the sensor on the center rod of the bobbin 18 senses the absence of yarn. After the control system recognizes this signal, it determines that the current bobbin needs to be replaced and sends a start command to the micro electric actuator. The extended end of the micro electric actuator pushes the connecting column 16 to move. The connecting column 16 slides in the guide grooves 15 on both sides of the connecting arm 14. The locking block 6 and the connecting arm 14 are an integral structure. The thrust of the connecting column 16 drives the connecting arm 14 to rotate around the circular shaft 13. Therefore, the locking block 6 rotates synchronously around the circular shaft 13 in the mounting groove 10. During the rotation of the locking block 6, its engagement with the locking groove 12 on the top of the slide plate 3 is released. At this time, the fixed constraint of the slide plate 3 is removed.

[0036] Subsequently, the compression spring 4 releases its elastic force, pushing the slide plate 3 to move outward. The spring 4 in the slide groove 8 of the base 2 returns to its deformation, generating elastic force to push the slider 5 to slide along the slide groove 8. The top of the slider 5 is connected to the slide plate 3, thus driving the slide plate 3 to move synchronously. When the slide plate 3 moves, the top limiting block 7 slides along the limiting groove 9 of the base 2. The limiting block 7 and the limiting groove 9 cooperate to ensure that the slide plate 3 pops out only in a straight line to avoid deviation. The slide plate 3 drives the empty yarn tube 18 on it to pop out to the outside of the base 2 until the slide plate 3 partially extends out of the base 2.

[0037] At this point, the empty yarn bobbin is fully exposed within the operator's reach, making it convenient for the operator to replace the yarn bobbin.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
