Description
Technical Field
[0001] The utility model relates to the technical field of circular weaving equipment, in particular to a circular weaving machine suitable for bobbins of different sizes. Background Art
[0002] Circular looms are machines used to weave circular or tubular fabrics and are widely used in a variety of industries, including textiles, construction, and chemicals. In the textile industry, circular looms are primarily used to produce various types of woven fabrics, such as woven bags and mesh bags. These products are widely used in agriculture, building materials, and food packaging. For example, woven bags are indispensable for packaging cement, fertilizers, and grain. Technological advances have significantly improved the production efficiency and product quality of circular looms. The construction industry is one of the largest users of circular looms, accounting for approximately 40% of the total market share.
[0003] In the prior art, in the design of current circular looms, the bobbin fixing assembly is usually designed to only adapt to bobbin diameters within a certain range, so that the assembly cannot fully demonstrate its due fixing effect when dealing with bobbins of different diameters, resulting in obvious limitations in its application. Since this fixing assembly lacks sufficient adaptability and flexibility, when encountering bobbins of different diameters, it is often impossible to achieve stable and effective adaptation, which limits the scope of application of the circular loom when facing diversified production needs. Operators need to frequently adjust or replace the fixing assembly to adapt to bobbins of different diameters, which not only increases the complexity of operation, but also reduces production efficiency. In addition, unsuitable fixing assemblies cause the bobbin to be unstable in position during the production process, which in turn affects the quality and output of polypropylene filaments, increasing production costs and time delays. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a circular loom suitable for bobbins of different sizes.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a circular loom suitable for bobbins of different sizes, comprising a workbench, a placing plate fixed on one side of the workbench, a base fixed on the top of the placing plate, a mounting cylinder fixed on the top of the base, a front groove provided on the circumference of the mounting cylinder, an inner extension piece fixed on the inner wall of the mounting cylinder, an inner slide groove provided on the inner wall of the front groove, a round head fastener slidably connected to the inner wall of the inner slide groove, a sliding column fixed on one side of the round head fastener, a limiting disk fixed on one end of the sliding column, a return spring fixed on the circumference of the sliding column close to the round head fastener, and the return spring The other end is fixed to the inner wall of the mounting cylinder near one end of the limiting disk. In the prior art, in the design of current circular looms, the bobbin fixing assembly is usually designed to only adapt to the bobbin diameter within a certain range, so that the assembly cannot fully demonstrate its due fixing effect when dealing with bobbins of different diameters, resulting in obvious limitations in its application. Since this fixing assembly lacks sufficient adaptability and flexibility, when encountering bobbins of different diameters, it is often impossible to achieve stable and effective adaptation, which limits the scope of application of the circular loom in the face of diversified production needs. The operator needs to frequently adjust or replace the fixing assembly. The components are used to adapt to the different diameters of the wire bobbins, which not only increases the complexity of operation, but also reduces production efficiency. In addition, the incompatible fixing components lead to the unstable position of the wire bobbins during the production process, which in turn affects the quality and output of the polypropylene filament, increases the cost of production and time delays. In response to such problems, the utility model adopts the method of installing round head fasteners to solve them. When the staff needs to fix the wire bobbin to the installation barrel, the wire bobbin is aligned with the installation barrel and slides in. When the wire bobbin contacts the round head fastener, since the top of the round head fastener is round, the wire bobbin presses the round head fastener to be retracted into the inner slide groove, and at the same time pushes the slide column inward. The reset spring is compressed and accumulates elastic potential energy. When the wire bobbin passes through, the reset spring releases the elastic potential energy to pop out the round head fastener, preventing the wire bobbin from leaving the mounting barrel without affecting the rotation of the wire bobbin during production. According to actual conditions, this mechanism can fix a wire bobbin with a diameter larger than the mounting barrel diameter and a diameter smaller than the sum of the mounting barrel diameter and the longest length diameter of the round head fastener, thereby greatly improving the applicability of the equipment. When the staff needs to remove the wire bobbin, they pull the limiting disk outward or pry up the limiting disk with a tool to retract the round head fastener, thereby facilitating disassembly, thereby improving the applicability of the equipment and improving user experience.
[0006] Preferably, a top carrier plate is fixed to the bottom of the workbench, a top sliding frame is fixed to the bottom of the top carrier plate, a shock-absorbing spring is fixed to the top of the inner wall of the top sliding frame, an inner slider is fixed to one end of the shock-absorbing spring, the circumference of the inner slider is slidably connected to the inner wall of the top sliding frame, and a bottom carrier plate is fixed to the bottom of the inner slider. In the prior art, the vibration generated when the equipment is running will directly affect the tension control of the polypropylene thread. The polypropylene thread needs to maintain a certain tension during the weaving process to ensure the uniformity and quality of the fabric. However, due to the presence of vibration, the tension of the polypropylene thread will become unstable, resulting in inconsistent tightness and uneven needle holes in the knitted fabric, affecting the overall appearance and performance. Secondly, vibration also causes slight displacement or friction between the mechanical parts of the circular loom. These subtle changes will interfere with the accuracy and stability of the equipment. For example, the knitting needles and the polypropylene thread will not be in a uniform state. The alignment between the yarns will be disturbed by vibration, resulting in needle breakage, missed stitches and other phenomena, which in turn affects the integrity and consistency of the knitted fabric. In addition, continuous vibration also causes some parts of the equipment to wear out prematurely, which not only increases the maintenance cost of the equipment, but also introduces more production defects without knowing it. In the long run, vibration will also affect the service life of the equipment itself, increasing the investment burden of the enterprise. To solve this problem, the utility model adopts the method of installing an inner slider to solve it, so that when the equipment is in production, the vibration is transmitted to the top load plate, and the shock-absorbing spring absorbs the vibration and converts it into elastic potential energy. When the shock-absorbing spring releases the elastic potential energy, the friction between the top sliding frame and the inner slider prevents it from being released, and converts the elastic potential energy into internal energy through friction, making the operation of the equipment more stable, reducing the impact of vibration, and achieving the effect of improving the yield rate.
[0007] Preferably, a pry point is fixed on one side of the top of the inner extension, and a pry groove is opened on one side of the top of the pry point. In the prior art, when the staff remove the wire bobbin, some staff will use the installation tube as a fulcrum to pry the limiting disk, which can easily cause damage and serious wear to the top of the installation tube, resulting in a reduced service life of the component, and even cause the installation tube to bend and skew, resulting in the equipment being unable to be installed and used normally, resulting in a significant increase in subsequent maintenance costs. To address such problems, the utility model adopts the method of installing a pry point to solve the problem, so that when the staff needs to pry the limiting disk, they can use the pry point as a fulcrum to pry, and temporarily clamp tools such as screwdrivers through the pry groove of the pry point to prevent them from shifting. At the same time, the pry point prevents damage to the component by evenly distributing the pressure through buffering, thereby achieving the effect of increasing the service life of the equipment.
[0008] Preferably, a top extension piece is fixed to the inner wall of the installation cylinder, and a hand pressure plate is fixed to the top of the top extension piece, which is convenient for staff to exert force and improves user experience.
[0009] Preferably, an L-shaped enclosure is fixed on the top of the bottom carrier plate, and the side surface of the L-shaped enclosure is set as an outer inclined surface to prevent foreign matter from falling into the shock absorbing component, thereby improving production safety.
[0010] Preferably, a rubber platform is fixed to the bottom of the bottom carrier plate, and the shock absorbing effect of the rubber platform is further improved, while the noise is reduced and the user experience is improved.
[0011] Preferably, a cross anti-skid groove is provided at the bottom of the rubber platform to prevent the equipment from slipping and improve the stability of the equipment.
[0012] Beneficial effects:
[0013] 1. In the prior art, in the design of current circular looms, the bobbin fixing assembly is usually designed to only adapt to the bobbin diameter within a certain range, so that the assembly cannot fully demonstrate its due fixing effect when dealing with bobbins of different diameters, resulting in obvious limitations in its application. Since this fixing assembly lacks sufficient adaptability and flexibility, when encountering bobbins of different diameters, it is often unable to achieve stable and effective adaptation, which limits the scope of application of the circular loom when facing diversified production needs. Operators need to frequently adjust or replace the fixing assembly to adapt to bobbins of different diameters, which not only increases the complexity of operation, but also reduces production efficiency. In addition, unsuitable fixing assemblies cause the bobbin to be unstable in position during the production process, thereby affecting the quality and output of polypropylene yarn, increasing production costs and time delays. To address such problems, the utility model adopts an installation method. When the thread drum is removed, the staff pulls the limiting disk outward or pries up the limiting disk with a tool to retract the round head fastener, thereby facilitating disassembly and improving the application range of the equipment and user experience.
[0014] 2. In the existing technology, the vibration generated during the operation of the equipment will directly affect the tension control of the polypropylene thread. The polypropylene thread needs to maintain a certain tension during the weaving process to ensure the uniformity and quality of the fabric. However, due to the existence of vibration, the tension of the polypropylene thread will become unstable, resulting in inconsistent tightness and uneven needle holes in the knitted fabric, affecting the overall appearance and performance. Secondly, the vibration also causes slight displacement or friction between the mechanical parts of the circular loom. These subtle changes will interfere with the accuracy and stability of the equipment. For example, the alignment between the knitting needle and the polypropylene thread will be disturbed by the vibration, resulting in needle breakage, missed stitches, etc., which in turn affects the integrity and consistency of the knitted fabric. In addition, continuous vibration also causes some parts of the equipment to wear out prematurely, which not only increases the maintenance cost of the equipment, but also introduces more production defects without knowing it. In the long run, vibration will also affect the service life of the equipment itself, increasing the investment burden of the enterprise. To solve this problem, the utility model adopts the method of installing an inner slider to solve it, so that when the equipment is in production, the vibration is transmitted to the top load plate, and the shock-absorbing spring absorbs the vibration and converts it into elastic potential energy. When the shock-absorbing spring releases the elastic potential energy, the friction between the top sliding frame and the inner slider prevents it from being released, and the elastic potential energy is converted into internal energy through friction, so that the operation of the equipment becomes smoother, the impact of vibration is reduced, and the yield rate is improved.
[0015] 3. In the prior art, when the staff remove the wire bobbin, some staff will use the installation barrel as a fulcrum to pry the limiting disk, which can easily cause damage and serious wear to the top of the installation barrel, resulting in a reduced service life of the component, and even cause the installation barrel to bend and skew, resulting in the equipment being unable to be installed and used normally, resulting in a significant increase in subsequent maintenance costs. To address this problem, the utility model adopts a method of installing a prying point to solve it. When the staff needs to pry the limiting disk, they can use the prying point as a fulcrum to pry, and temporarily clamp tools such as screwdrivers through the prying groove of the prying point to prevent them from shifting. At the same time, the prying point prevents damage to the component by evenly distributing the pressure through buffering, thereby achieving the effect of increasing the service life of the equipment.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:
[0026] Reference Figure 1-5A circular loom suitable for bobbins of different sizes includes a workbench 1, a placing plate 101 is fixed on one side of the workbench 1, a base 2 is fixed on the top of the placing plate 101, a mounting cylinder 201 is fixed on the top of the base 2, a front groove 202 is provided on the circumference of the mounting cylinder 201, an inner extension 203 is fixed on the inner wall of the mounting cylinder 201, an inner slide groove 205 is provided on the inner wall of the front groove 202, a round head fastener 204 is slidably connected to the inner wall of the inner slide groove 205, a slide column 206 is fixed on one side of the round head fastener 204, a limiting disk 207 is fixed on one end of the slide column 206, a return spring 208 is fixed on the circumference of the slide column 206 close to the round head fastener 204, and the return spring 208 is fixed on the circumference of the slide column 206. 08 The other end is fixed to the inner wall of the mounting cylinder 201 near one end of the limiting disk 207. In the current design of circular looms, the bobbin fixing assembly is usually designed to only adapt to bobbin diameters within a certain range, so that the assembly cannot fully demonstrate its due fixing effect when dealing with bobbins of different diameters, resulting in obvious limitations in its application. Since this fixing assembly lacks sufficient adaptability and flexibility, when encountering bobbins of different diameters, it is often unable to achieve stable and effective adaptation, which limits the scope of application of the circular loom when facing diversified production needs. Operators need to frequently adjust or replace the fixing assembly to adapt to bobbins of different diameters. This not only increases the complexity of operation, but also reduces production efficiency. In addition, the incompatible fixing components cause the position of the bobbin to be unstable during the production process, which in turn affects the quality and output of the polypropylene filament, increases the cost of production and time delays. The problem is solved by installing a round-head fastener 204. When the staff needs to fix the bobbin to the installation barrel 201, the bobbin is aligned with the installation barrel 201 and slides in. When the bobbin contacts the round-head fastener 204, since the top of the round-head fastener 204 is a round head, the bobbin presses the round-head fastener 204 to be retracted into the inner slide groove 205, and at the same time pushes the slide column 206 inward, so that the return spring 208 is compressed, accumulating Elastic potential energy. When the bobbin passes through, the return spring 208 releases the elastic potential energy to pop out the round head fastener 204, preventing the bobbin from leaving the mounting barrel 201, while not affecting the rotation of the bobbin during production. According to actual conditions, this mechanism can fix a bobbin whose diameter is larger than the diameter of the mounting barrel 201 and smaller than the sum of the diameter of the mounting barrel 201 and the longest length diameter of the round head fastener 204, thereby greatly improving the applicability of the equipment. When the staff needs to remove the bobbin, they pull the limiting disk 207 outward or pry up the limiting disk 207 with a tool to retract the round head fastener 204, thereby facilitating disassembly, thereby improving the applicability of the equipment and improving user experience.A pry point 4 is fixed on one side of the top of the inner extension 203, and a pry groove 401 is opened on one side of the top of the pry point 4. When the staff removes the wire bobbin, some staff will use the installation tube 201 as a fulcrum to pry the limiting disk 207, which can easily cause damage and serious wear to the top of the installation tube 201, resulting in a reduced component life, and even causing the installation tube 201 to bend and tilt, resulting in the equipment being unable to be installed and used normally, causing subsequent maintenance costs to increase significantly. The installation pry point 4 is used to solve this problem. When the staff needs to pry the limiting disk 207, they can use the pry point 4 as a fulcrum to pry, and temporarily clamp tools such as screwdrivers through the pry groove 401 of the pry point 4 to prevent them from shifting. At the same time, the pry point 4 prevents damage to the component by evenly distributing the pressure, thereby increasing the service life of the equipment. A top extension piece 5 is fixed to the inner wall of the installation tube 201, and a hand pressure plate 501 is fixed on the top of the top extension piece 5 to facilitate the staff to exert force and improve the user experience.
[0027] A top carrier plate 3 is fixed to the bottom of the workbench 1, a top sliding frame 301 is fixed to the bottom of the top carrier plate 3, a shock-absorbing spring 303 is fixed to the top of the inner wall of the top sliding frame 301, an inner slider 302 is fixed to one end of the shock-absorbing spring 303, the circumference of the inner slider 302 is slidably connected to the inner wall of the top sliding frame 301, and a bottom carrier plate 304 is fixed to the bottom of the inner slider 302. The vibration generated when the equipment is running will directly affect the tension control of the polypropylene thread. The polypropylene thread needs to maintain a certain tension during the weaving process to ensure the uniformity and quality of the fabric. However, due to the presence of vibration, the tension of the polypropylene thread will become unstable, resulting in inconsistent tightness and uneven needle holes in the knitted fabric, affecting the overall appearance and performance. Secondly, the vibration also causes slight displacement or friction between the mechanical parts of the circular loom. These subtle changes will interfere with the accuracy and stability of the equipment. Vibration can disrupt the alignment of polypropylene threads, leading to needle breakage and missed stitches, which in turn affects the integrity and consistency of the knitted fabric. Furthermore, continuous vibration can cause premature wear of some equipment components, increasing maintenance costs and unknowingly introducing more production defects. In the long run, vibration can also impact the service life of the equipment itself, increasing the company's investment burden. This problem is addressed by installing an inner slider 302. During production, vibration is transmitted to the top carrier plate 3, where the damping spring 303 absorbs the vibration and converts it into elastic potential energy. When the damping spring 303 releases its elastic potential energy, the friction between the top slide frame 301 and the inner slider 302 prevents it from releasing the energy. This friction converts the elastic potential energy into internal energy, making the equipment run more smoothly, reducing the impact of vibration, and improving the yield rate. An L-shaped enclosure 305 is fixed to the top of the bottom carrier plate 304. The side of the L-shaped enclosure 305 is designed with an outer bevel 306 to prevent foreign matter from falling into the damping assembly, improving production safety. A rubber platform 307 is fixed to the bottom of the bottom carrier plate 304. The cushioning effect of the rubber platform 307 is further improved, while reducing noise and improving the user experience. The bottom of the rubber platform 307 is provided with a cross anti-skid groove to prevent the device from slipping and improve the stability of the device.
[0028] When the thread drum passes through, the return spring 208 releases the elastic potential energy to eject the round head fastener 204, preventing the thread drum from leaving the installation drum 201. At the same time, it does not affect the rotation of the thread drum during production. According to actual conditions, this mechanism can fix a thread drum with a diameter larger than the diameter of the installation drum 201 and a diameter smaller than the sum of the diameter of the installation drum 201 and the longest length diameter of the round head fastener 204, thereby greatly improving the applicability of the equipment. When the staff needs to remove the thread drum, they pull the limiting disk 207 outward or pry up the limiting disk 207 with a tool to retract the round head fastener 204, thereby conveniently removing it.
