By setting a protective mechanism, the protective plate on the protective mechanism can protect the surface of the weft knitting machine body from collision damage. When the protective plate is impacted, it will move towards one side of the weft knitting machine body. The buffer spring set therein can buffer the impact and reduce the impact, thereby protecting the weft knitting machine body.

[0004] However, the protective mechanism in the aforementioned patent is only set on both sides of the weft knitting machine, and can only provide buffer protection for the weft knitting machine from the left and right sides. The protection effect in other directions is poor, the protection range is small and it is inconvenient to disassemble. At the same time, its small dust suction cover has limited effect on removing dust and lint generated during the use of the weft knitting machine, and it is inconvenient to disassemble and install, resulting in poor dust removal effect. Utility Model Content

[0005] The purpose of this utility model is to provide a single-sided weft knitting machine with dust-proof effect, so as to solve the problems mentioned in the background art that the weft knitting machine can only provide buffer protection from the left and right sides, with poor protection effect in other directions, small protection range and inconvenient disassembly, and the small dust suction hood has limited effect on removing dust and flying lint generated during the use of the weft knitting machine, and is inconvenient to disassemble and the dust removal effect is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-sided weft knitting machine with dust-proof effect, comprising a weft knitting machine body and an alarm, wherein a protective component is movably installed on the outside of the weft knitting machine body, and a mounting slot is provided on the upper part of the outside of the weft knitting machine body, and a dust-collecting component is movably installed on the mounting slot and the outside of the weft knitting machine body;

[0007] The protective component includes a locking frame that is fixedly installed on the outside of the weft knitting machine body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a single-sided weft knitting machine with dust prevention effect, including a weft knitting machine body 1 and an alarm 5. A protective component 2 is movably installed on the outside of the weft knitting machine body 1. A mounting slot 3 is opened on the upper part of the outside of the weft knitting machine body 1. A dust collection component 4 is movably installed on the mounting slot 3 and the outside of the weft knitting machine body 1.

[0025] The protective component 2 includes a retaining frame 21 fixedly installed on the outside of the weft knitting machine body 1. The retaining frame 21 has a retaining groove 22 inside, and a retaining strip 23 is movably engaged inside the retaining groove 22. A cushioning airbag 24 is fixedly connected to the outside of the retaining strip 23. An injection pipe 25 and a deflation pipe 26 are fixedly connected to the bottom of the cushioning airbag 24. A rubber soft plate 27 is fixedly connected to the outside of the cushioning airbag 24.

[0026] By engaging the locking strip 23 into the corresponding slot 22 on the outside of the weft knitting machine body 1, the buffer airbag 24 is fixed to the outside of the weft knitting machine body 1, thus surrounding it for easy disassembly and maintenance. Inflation of the buffer airbag 24 is achieved through the injection pipe 25 for protection. When the rubber sheet 27 is impacted, it disperses the impact force, expanding the force-bearing area. The rubber sheet 27 compresses the inner buffer airbag 24, providing cushioning space through deformation, thereby reducing the impact and increasing the protection range to ensure multi-faceted protection.

[0027] The retaining brackets 21 are arranged in a ring at equal intervals on the outside of the weft knitting machine body 1. The retaining slots 22 have top openings to facilitate the insertion and removal of the retaining strips 23. This ring-shaped, equidistant arrangement of the retaining brackets 21 not only ensures that the cushioning airbags 24 can evenly and tightly surround the weft knitting machine body 1, but also makes the entire protective assembly 2 structurally more stable, enhancing the protective effect. The top opening design of the retaining slots 22 simplifies the installation process of the retaining strips 23, making operation simpler and faster.

[0028] The locking strip 23 has a "T"-shaped cross-section that matches the buffer airbag 24, allowing the locking strip 23 to be securely locked into the locking groove 22 and tightly fitted to the outer wall of the buffer airbag 24, effectively preventing the buffer airbag 24 from shifting or falling off during use.

[0029] An electronic barometer 28 is fixedly installed on the top of the air cushion 24. The electronic barometer 28 is electrically connected to the alarm 5. The electronic barometer 28 can monitor the air pressure changes inside the air cushion 24 in real time. When the weft knitting machine body 1 is impacted, causing the air cushion 24 to be squeezed and deformed, the internal air pressure will change accordingly. Once the air pressure change exceeds the preset safety range, the electronic barometer 28 will immediately trigger the alarm 5 to sound an alarm, reminding the operator to take timely countermeasures. This improves the safety of the weft knitting machine during use and can effectively prevent equipment damage or personal injury caused by collisions and impacts, further enhancing the reliability and practicality of the equipment.

[0030] Please see Figure 4 and Figure 5 The vacuuming assembly 4 includes a negative pressure vacuum cleaner 41, a first retaining ring 42, and a second retaining ring 43. The negative pressure vacuum cleaner 41 is movably engaged with the outside of the weft knitting machine body 1. One end of the first retaining ring 42 and the second retaining ring 43 are movably hinged and engaged with the outside of the mounting groove 3. The other end of the first retaining ring 42 and the second retaining ring 43 is fixedly connected to an ear plate 44. A fixing bolt 45 is movably installed inside the ear plate 44. A vacuum hood 46 is fixedly installed on the top of the first retaining ring 42 and the second retaining ring 43. A connector 47 is provided on the outside of the vacuum hood 46. A vacuum hose 48 is fixedly connected between the negative pressure vacuum cleaner 41 and the connector 47.

[0031] The negative pressure vacuum cleaner 41 generates powerful suction to efficiently draw dust and fiber debris generated by the weft knitting machine 1 during operation into the dust hood 46. This debris is then transported through the suction pipe 48 to the negative pressure vacuum cleaner 41 for centralized processing. This effectively reduces the spillage of dust and lint around the weft knitting machine 1, minimizing its impact on operation and improving cleanliness and efficiency. Furthermore, the design of the retaining rings 42 and 43 allows for easy installation and removal of the vacuum assembly 4, facilitating maintenance and cleaning by operators.

[0032] The dust hoods 46 are semi-circular and symmetrically positioned at the top of the retaining rings 42 and 43. The semi-circular dust hoods 46 can more comprehensively cover the working area of ​​the weft knitting machine body 1, ensuring that dust and fiber debris are effectively sucked in, reducing blind spots and further improving suction efficiency.

[0033] The dust suction hood 46 has suction ports evenly spaced on its inner side. The dust suction hood 46 is located on the outer side of the needle plate of the weft knitting machine body 1. The design of the suction ports allows the dust suction hood 46 to absorb dust and lint more evenly, avoiding situations where the suction is too strong or too weak in some areas, thus ensuring the stability and uniformity of the suction effect. The dust suction hood 46 is located on the outer side of the needle plate of the weft knitting machine body 1, which can effectively remove dust without interfering with the normal operation of the weft knitting machine body 1, thus ensuring the operational stability and knitting quality of the weft knitting machine body 1.

[0034] Working principle: By corresponding the locking strips 23 on the inner side of the buffer airbag 24 to the locking frame 21 on the outer side of the weft knitting machine body 1, the locking strips 23 are inserted from the top opening of the locking slot 22. The locking strips 23 are fully inserted into the locking slot 22 to fix the buffer airbag 24 to the outside of the weft knitting machine body 1 and surround it. Then, the external inflation mechanism connects to the injection pipe 25 to inflate the buffer airbag 24. When the rubber soft plate 27 is impacted, the rubber soft plate 27 disperses the impact force and expands the force-bearing area. The rubber soft plate 27 squeezes the buffer airbag 24 on its inner side. The buffer airbag 24 is squeezed and deformed to provide buffer space to reduce the impact. The change in internal pressure when the buffer airbag 24 is squeezed is monitored by the electronic barometer 28. If it exceeds the set range, the data is sent to the alarm 5 to alarm and attract the staff.

[0035] Dust and lint generated during the operation of the weft knitting machine 1 are drawn into the dust and lint by the negative pressure vacuum cleaner 41. The dust and lint are then drawn into the dust suction hood 46 via the suction pipe 48 and transported to the inside of the negative pressure vacuum cleaner 41. The annularly arranged dust suction hood 46, located outside the needle plate, ensures effective dust and lint removal. The negative pressure vacuum cleaner 41 is mounted on the outside of the weft knitting machine 1. By removing the fixing bolts 45, the retaining rings 42 and 43 can be opened by rotating them outwards from the hinged position and removed from the outside of the weft knitting machine 1 for easy maintenance.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] 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.
