Description

Technical Field

[0001] This utility model relates to the field of water jet loom protection technology, and in particular to a protective mechanism. Background Technology

[0002] Water jet looms are shuttleless looms that use jets of water to guide the weft yarn through the shed. The frame guard is designed to prevent dust, chips, and hard sand from entering the loom, reducing damage from hard particles and minimizing the impact of operational deformation. The guard surface should be smooth, free of burrs and sharp edges, and should not become a new source of danger. The installation and removal of existing dustproof plastic shells for water jet looms are cumbersome, leading to significant inconvenience in maintenance and cleaning.

[0003] For example, a detachable protective cover for a water-jet loom disclosed in Chinese patent literature (publication number: CN218880219U) allows the protective cover to be quickly installed on the device body through the sliding action of a slider and a groove, and the insertion block is limited and inserted into the corresponding matching slot under the action of the elastic potential energy of the spring, thereby completing the fixed installation of the protective cover assembly. When it is necessary to remove it, it is only necessary to reverse the operation. Compared with traditional protective covers, it has the advantages of quick disassembly and assembly, simple structure, and easy maintenance and cleaning.

[0004] However, since the slider needs to press the pressure plate during disassembly, the pressure plate needs to be higher than the main body of the device. This results in a large gap between the protective cover and the main body of the device, which reduces the protective performance of the internal water jet loom. After long-term use, a large amount of dust will clog the nozzles of the water jet loom, resulting in insufficient weft yarn traction and quality problems such as weft breakage and sparse or dense weft threads in the fabric. At the same time, it increases the frequency of equipment shutdown for cleaning, which seriously affects production efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Current protective covers have blind spots when protecting water-jet looms, which allows dust to seep in and affects production efficiency and quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective mechanism includes a water jet loom body, wherein a flipping mechanism is provided on the back of the water jet loom body;

[0008] The flipping mechanism includes a mounting plate, the front of which is fixedly connected to the back of the water jet loom body. A symmetrically distributed support block is fixedly connected to the upper end of the mounting plate. A rotating rod is rotatably connected to the inner wall of each of the two support blocks via bearings. A symmetrically distributed connecting block is fixedly sleeved on the outside of each rotating rod. An arc-shaped protective cover is fixedly connected to one end of each of the two connecting blocks. The lower end of the arc-shaped protective cover contacts the upper end of the water jet loom body.

[0009] The protective cover is provided with an opening and closing mechanism on its exterior.

[0010] Preferably, a worm gear is fixedly sleeved on the outside of the rotating rod, a mounting block is fixedly connected to the upper end of the mounting plate, and a worm is rotatably connected to the inner wall of the mounting block through a bearing.

[0011] Preferably, the outer surface of the worm meshes with the tooth surface of the worm wheel, and a drive handwheel is fixedly connected to one end of the worm.

[0012] Preferably, the opening and closing mechanism includes arc-shaped limiting strips, the inner sides of the two arc-shaped limiting strips are symmetrically distributed and fixedly connected to the outer side of the arc-shaped protective cover, the outer side of the arc-shaped limiting strips is provided with limiting slots distributed in an arc-shaped array, and the outer side of the arc-shaped protective cover is provided with maintenance slots.

[0013] Preferably, the inner top wall of the inspection slot is provided with an arc-shaped storage groove, the inner wall of the arc-shaped storage groove is slidably fitted with an arc-shaped protective plate, and the outer side of the arc-shaped protective plate is fixedly connected with a drive handle.

[0014] Preferably, the drive handle has symmetrically distributed travel grooves on both sides, and a limiting slide rod is slidably connected to the inner wall of the travel groove. One end of the limiting slide rod is slidably engaged with the inner wall of one of the limiting groove openings.

[0015] Preferably, each of the two limiting slide rods has a handle fixedly connected to one end facing the other, and a set of return springs arranged in a linear array are fixedly connected to the upper end of the handle.

[0017] In this invention, the worm gear, worm, and rotating rod in the flipping mechanism can achieve the overall flipping of the arc-shaped protective cover, facilitating large-scale cleaning and maintenance. The opening and closing mechanism, using the arc-shaped protective plate, limit slide rod, and return spring, can quickly open the inspection slot for small-scale maintenance and can limit and fix the arc-shaped protective plate. At the same time, the arc-shaped protective cover can fit tightly against the water jet loom body without obvious gaps, effectively blocking the intrusion of foreign objects such as dust and chips, ensuring that the internal components of the water jet loom are not damaged, and improving the equipment's protective performance and the convenience of inspection and maintenance.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Example

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a protective mechanism, including a water jet loom body 1, a flipping mechanism on the back of the water jet loom body 1, and a mounting component based on a mounting plate 2. The front of the mounting plate 2 is fixedly connected to the back of the water jet loom body 1, providing a stable mounting foundation for the entire flipping mechanism and ensuring that the flipping mechanism will not loosen or shift due to factors such as vibration during the operation of the water jet loom.

[0030] The mounting plate 2 has symmetrically distributed support blocks 21 fixedly connected to the upper end. The inner wall of the support blocks 21 is connected to the rotating rod 22 through the bearing. The rod can rotate stably under the support of the support blocks 21, providing a rotation axis for the flipping of the arc-shaped protective cover 24.

[0031] The symmetrically distributed connecting blocks 23 fixedly sleeved on the outside of the rotating rod 22 convert the rotation of the rotating rod 22 into the flipping action of the arc-shaped protective cover 24. The arc-shaped protective cover 24, which is fixedly connected to one end of each of the two connecting blocks 23, is in close contact with the upper end of the water jet loom body 1 at the lower end. This effectively prevents foreign objects such as dust, chips, and hard sand from entering the interior of the water jet loom, greatly reducing the damage of hard particulate foreign objects to the internal components of the water jet loom, ensuring the normal operation of the internal components, reducing the equipment failure rate, and extending the service life of the equipment.

[0032] The worm gear 25, which is fixedly sleeved on the outside of the rotating rod 22, meshes with the worm 27, which is rotatably connected to the inner wall of the mounting block 26 through a bearing. The drive handwheel 28, which is fixedly connected to one end of the worm 27, provides a convenient operating component for the operator.

[0033] When the operator turns the drive handwheel 28, it drives the worm gear 27 to rotate, which in turn drives the rotating rod 22 to rotate through the worm wheel 25, thus realizing the flipping of the arc-shaped protective cover 24. This worm wheel 25 and worm gear 27 transmission method has the characteristics of smooth transmission and good self-locking, which can make the arc-shaped protective cover 24 stable when flipped to any angle, and will not rotate on its own due to its own weight or slight external vibration, thus ensuring the safety and stability of operation.

[0034] Meanwhile, the overall flipping method eliminates the need to disassemble the protective cover, saving a significant amount of disassembly and assembly time compared to traditional methods. This improves the efficiency of large-scale maintenance and makes it easier for operators to perform large-scale overall cleaning and maintenance of the water jet loom, such as cleaning internal dust and inspecting and maintaining multiple components.

[0035] The opening and closing mechanism outside the protective cover uses arc-shaped limiting strips 3 as limiting components. The inner sides of the two arc-shaped limiting strips 3 are symmetrically distributed and fixedly connected to the outer side of the arc-shaped protective cover 24. The limiting slots 31 arranged in an arc-shaped array on the outer side of the arc-shaped limiting strips 3 provide multiple limiting fixing points for the limiting slide rod 37.

[0036] The inspection slot 32 on the outside of the arc-shaped protective cover 24 provides a passage for small-scale maintenance, making it convenient for operators to conduct local inspections and maintenance on the inside of the water jet loom.

[0037] The arc-shaped storage groove 33 is opened on the inner top wall of the inspection slot 32, and the arc-shaped protective plate 34 is slidably sleeved on the inner wall. It can slide smoothly in the arc-shaped storage groove 33 to realize the opening and closing of the inspection slot 32. The drive handle 35 is fixedly connected to the outer side of the arc-shaped protective plate 34, which makes it convenient for operators to push the arc-shaped protective plate 34 and improves the convenience of operation.

[0038] The drive handle 35 has symmetrically distributed travel grooves 36 on both sides, and a limiting slide rod 37 that is slidably connected to the inner wall. One end of the rod is slidably engaged with the inner wall of one of the limiting grooves 31, which can limit and fix the arc-shaped protective plate 34.

[0039] Two limiting slide rods 37 are fixedly connected to a handle 38 at one end, and a set of return springs 39 arranged in a linear array are fixedly connected to the upper end of the handle 38. One end of each set of return springs 39 is fixedly connected to the inner top wall of the drive handle 35, providing elastic force for the reset of the limiting slide rods 37.

[0040] When the operator pulls the handle 38, the limiting slide bar 37 overcomes the elastic force of the return spring 39 and disengages from the limiting slot 31, which can push the arc-shaped protective plate 34 to open the maintenance slot 32. When the arc-shaped protective plate 34 is opened to a suitable angle, the handle 38 is released, and the elastic force of the return spring 39 will drive the handle 38 and the limiting slide bar 37 to return to their original positions, so that the limiting slide bar 37 is locked into the corresponding limiting slot 31, which limits and fixes the arc-shaped protective plate 34, preventing the arc-shaped protective plate 34 from falling off during maintenance and ensuring the safety and stability of maintenance operations.

[0041] In this way, operators can quickly open the inspection slot 32 to perform small-scale maintenance and repairs, such as checking the operating status of some parts. Compared with the traditional method, the operation efficiency is improved and the safety is higher.

[0042] The working process of this utility model:

[0043] Step one: When a minor overhaul of the water jet loom is required, the operator holds the drive handle 35 and pulls the lever 38. The movement of the lever 38 compresses the return spring 39, causing the limiting slide rod 37, which is fixedly connected to the lever 38, to overcome the elastic force of the return spring 39 and disengage from the limiting slot 31. Next, the operator pushes the arc-shaped protective plate 34 along the arc-shaped storage groove 33. The arc-shaped protective plate 34 slides within the arc-shaped storage groove 33, gradually opening the maintenance slot 32. When the arc-shaped protective plate... After opening 34 to the appropriate angle, release the handle 38. At this time, the elastic force of the return spring 39 will drive the handle 38 and the limit slide bar 37 to return to their original positions, so that the limit slide bar 37 is engaged in the corresponding limit slot 31, thereby limiting and fixing the arc-shaped protective plate 34 to prevent the arc-shaped protective plate 34 from falling off during maintenance, ensuring the safety and stability of the maintenance operation. The operator can perform small-scale maintenance and repair on the inside of the water jet loom through the opened maintenance slot 32, such as checking the operating status of some parts.

[0044] Step 2: When a large-scale overall cleaning and maintenance of the water jet loom is required, the operator turns the drive handwheel 28, which drives the worm 27 to rotate. Since the outer surface of the worm 27 meshes with the tooth surface of the worm wheel 25, the rotation of the worm 27 will drive the worm wheel 25 to rotate. The worm wheel 25 is fixedly sleeved on the outside of the rotating rod 22. The rotation of the worm wheel 25 will then drive the rotating rod 22 to rotate. The rotating rod 22, through the fixedly sleeved connecting block 23, drives the arc-shaped protective cover 24 to rotate around the rotating rod 22, thereby opening the arc-shaped protective cover 24 and separating it from the water jet loom body 1. At this time, most of the area of ​​the water jet loom body 1 is exposed, which makes it easier for the operator to carry out a large-scale overall cleaning and maintenance, such as cleaning the internal dust and inspecting and maintaining multiple components.

[0045] Step 3: When no maintenance is required, the lower end of the arc-shaped protective cover 24 contacts the upper end of the water jet loom body 1, which can fit tightly and effectively prevent dust, chips, hard sand particles and other objects from entering the interior of the water jet loom, reducing the damage of hard particulate foreign objects to the interior of the water jet loom. At the same time, it can also reduce the impact of deformation of the interior of the water jet loom due to operation, ensuring the normal operation of the water jet loom.

[0046] 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.
