Description

Technical Field

[0001] This application relates to the technical field of looms, and particularly to a buffer, a shuttle box and a loom of a loom. Background Art

[0002] A loom is the most basic equipment in the textile industry and is also a common equipment for manufacturing commonly used items in people's lives, such as daily clothing, the base cloth of a papermaking felt for papermaking, or curtain fabrics, etc.

[0003] Currently, most commonly used looms are of the shuttle type, that is, shuttle looms, such as a circular loom that can be used to manufacture a circular endless base cloth. A shuttle loom includes a shuttle box, a shuttle rod and a shuttle. The shuttle rod strikes the stationary shuttle in the shuttle box through the leather knot on it, causing the shuttle to move back and forth, so as to weave the weft and the warp arranged regularly and variably together. However, due to the large shuttle throwing force of the shuttle rod, the shuttle continues to move rapidly due to inertia after completing the interweaving, resulting in the shuttle being unable to be buffered and stopped in the shuttle box, thus causing the shuttle or the shuttle rod to impact on the shuttle box, causing damage to related parts, and sometimes even the phenomenon of the shuttle returning, affecting the normal operation of the loom.

[0004] To solve the above problems, existing looms also install a braking buffer device outside the shuttle box. Most of the braking buffer devices use a dragon belt or a leather loop, and rely on the elasticity of the dragon belt or the leather loop to generate collisions to consume the remaining kinetic energy of the shuttle. However, due to the limitation of the elastic coefficient of this braking buffer device, the performance is unstable, it needs to be adjusted frequently, and the buffering effect is not good.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0022] To better understand the present application, the buffer, shuttle box, and loom provided by the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Generally speaking, in one aspect of the present application, a buffer for a loom is provided. The buffer includes a frame body, a cylinder, and a buffer member. The cylinder includes a cylinder body mounted on the frame body and a piston slidably disposed in the cylinder body. The piston further includes a piston rod that can extend out of the cylinder body, and the piston rod can move relative to the cylinder body along with the piston. The buffer member is slidably mounted on the frame body and can move relative to the frame body to push against the piston rod. The buffer member can move relative to the frame body to push against the piston rod, causing the piston rod and the piston connected to the piston rod to move relative to the cylinder body, so that the piston compresses the gas in the cylinder body, increasing the pressure of the gas and generating a reaction force acting on the buffer member. The reaction force is transmitted to the picking stick, preventing the picking stick from moving outward, and the reaction force is transmitted to the shuttle through the leather knot on the picking stick, thereby consuming the remaining energy of the shuttle and braking and stopping the shuttle in a short time.

[0024] Please refer to Figure 1 , Figure 1 FIG. is a simplified structural schematic diagram of an embodiment of the buffer of the loom provided by the present application. The buffer 100 of the loom of the present application includes a frame body 10, a cylinder 30, and a buffer member 50. The cylinder 30 includes a cylinder body 31, a piston 33, and a piston rod 35. The cylinder body 31 is fixedly mounted on the frame body 10 and is used to store gas. The piston 33 is slidably disposed in the cylinder body 31, that is, the piston 33 is disposed in the cylinder body 31 and can move within the cylinder body 31. One end of the piston rod 35 is fixedly connected to the piston 33, and the other end of the piston rod 35 extends out of the cylinder body 31. When the piston 33 is operated to move within the cylinder body 31, the piston rod 35 can move relative to the cylinder body 31 together with the piston 33. The buffer member 50 is slidably mounted on the frame body 10, and the buffer member 50 can move relative to the frame body 10 and can push against the piston rod 35 as it moves.

[0025] Optionally, in one embodiment, the materials of the frame body 10, the cylinder 30, and the buffer member 50 are iron. The higher carbon content of iron makes iron have greater hardness, and iron is not easily reacted with other simple substances in dry air, making the buffer 100 made of iron harder, more solid and reliable, and capable of being used outdoors for a long time.

[0026] The buffer 100 of the loom provided by the present application uses the buffer member 50 to push against the piston rod 35, so that the piston 33 connected to the piston rod 35 compresses the gas in the cylinder block 31, increasing the pressure of the gas, causing the buffer member 50 to receive a reaction force, thereby buffering and stopping the shuttle. Specifically, generally speaking, the existing loom includes a picking stick, a leather knot fixed on the picking stick, and a shuttle that moves when the picking stick strikes. The driving end where the picking stick strikes the shuttle is located between the shuttle and the buffer 100 of the loom provided by the present application. Therefore, after the shuttle completes a weft insertion operation, it will strike the leather knot, and the leather knot will push the picking stick towards the buffer 100. When the buffer member 50 receives the impact force from the picking stick, the buffer member 50 moves relative to the frame 10. As the buffer member 50 moves, the buffer member 50 collides with the piston rod 35. At the moment when the buffer member 50 and the piston rod 35 touch, it can be considered that the two move together at the same speed. That is to say, as the buffer member 50 moves, the buffer member 50 can push against the piston rod 35, causing the piston rod 35 and the buffer member 50 to move in the same direction and at the same speed, thereby pushing the piston 33 in the cylinder block 31 to move. Since the gas is easily compressed under the action of an external force, the pressure generated by the gas increases. As the moving stroke of the piston 33 relative to the cylinder block 31 increases, the gas in the cylinder block 31 is compressed, increasing the pressure in the cylinder block 31. As a result, the buffer member 50 pushed by the piston rod 35 receives a reaction force, and the reaction force is transmitted to the picking stick through the buffer member 50, preventing the picking stick from moving outward. Moreover, the reaction force is transmitted to the shuttle through the leather knot on the picking stick, effectively consuming the remaining energy of the shuttle and buffering and stopping the shuttle in a short time.

[0027] In order to reduce the wear when the buffer member 50 collides with and pushes against the piston rod 35, in one embodiment, a buffer pad 351 is further installed at one end of the piston rod 35 extending out of the cylinder block 31. The buffer pad 351 can be sleeved on the end of the piston rod 35, playing a role in protecting the piston rod 35, reducing the wear when the buffer member 50 collides with and pushes against the piston rod 35, and increasing the service life of the piston rod 35 and the buffer member 50. Moreover, the setting of the buffer pad 351 increases the contact area between the piston rod 35 and the buffer member 50, enabling the buffer member 50 to more easily and accurately push against the piston rod 35.

[0028] Furthermore, in other embodiments, a buffer pad 351 can also be installed at one end of the buffer member 50 in contact with the piston rod 35. Or a buffer pad 351 is only installed at one end of the buffer member 50 in contact with the piston rod 35, which can be specifically set according to actual usage needs and will not be specifically limited here.

[0029] Optionally, in one embodiment, the material of the buffer pad 351 is nylon. The nylon material has good wear resistance and elasticity, which can greatly improve the wear resistance and elasticity of the buffer pad 351, avoid the direct contact between the piston rod 35 and the buffer member 50, and reduce the wear generated when the piston rod 35 and the buffer member 50 collide and push against each other. It can be understood that in other embodiments, the buffer pad 351 can also be made of other materials, which can be specifically set according to actual use needs and will not be specifically limited here.

[0030] Please continue to refer to Figure 1 , in one embodiment, an air pump (not shown in the figure) is connected to the cylinder block 31. The air pump transmits gas into the cylinder block 31, and the amount of gas in the cylinder block 31 can be specifically set according to actual use needs and will not be specifically limited here. Taking the case where the amount of gas in the cylinder block 31 is sufficient as an example, when the amount of gas is large, a reverse force sufficient to consume the remaining energy of the shuttle can be generated when the gas is compressed to a small extent, reducing the movement of the piston 33 in the cylinder block 31, thereby reducing the friction between the piston 33 and the inner wall of the cylinder block 31, and further increasing the service life of the piston 33 and the cylinder block 31. Optionally, the outer shape of the cylinder block 31 can be a cube, a cuboid, etc., and will not be specifically limited here. The volume size of the cylinder block 31 can be specifically set according to actual use needs and will not be specifically limited here. It can be understood that the cylinder block 31 can be a single-acting cylinder, and the air pump only transmits gas to the part of the cylinder block 31 away from the piston rod 35 to a preset pressure. In other embodiments, the air pump can also transmit gas to both parts of the cylinder block 31 on both sides of the piston 33 at the same time, and the air pressure on the side away from the piston rod 35 is greater than the air pressure on the side close to the piston rod 35.

[0031] Optionally, in one embodiment, the gas in the cylinder block 31 is air. The distance between air molecules is large. Within a certain space range, air can be compressed under the action of an external force, so that the volume of air within this range decreases and the air pressure increases, providing a reverse force for the buffer member 50 to buffer and stop the shuttle. It can be understood that in other embodiments, the gas in the cylinder block 31 can also be other gases that can be compressed, which can be specifically set according to actual use needs and will not be specifically limited here.

[0032] Further, in an embodiment, a protective cover plate 311 is provided on the outer side wall of the cylinder block 31 facing the buffer member 50. When the air pressure in the cylinder block 31 is small or the impact force of the shuttle is too large, it is possible that the buffer member 50 moves to abut against the outer side wall of the cylinder block 31 facing the buffer member 50, so that the buffer member 50 collides with the cylinder block 31, which may cause the cylinder block 31 to rupture or affect the use of the cylinder block 31. The setting of the protective cover plate 311 plays a role in protecting the cylinder block 31, avoiding the direct collision between the buffer member 50 and the cylinder block 31, reducing the damage to the cylinder block 31, and increasing the service life of the cylinder block 31.

[0033] Understandably, in other embodiments, a protective cover plate 311 may also be provided on the inner wall of the cylinder block 31 facing the piston 33 and away from the bottom of the pushing rod 35. When the air pressure in the cylinder block 31 is small or the impact force of the shuttle is too large, it is possible that the force of the buffer member 50 pushing the pushing rod 35 is too large, causing the piston 33 to move to abut against the bottom of the cylinder block 31, so that the piston 33 collides with the cylinder block 31, which may cause the cylinder block 31 to rupture or affect the use of the cylinder block 31. The setting of the protective cover plate 311 plays a role in protecting the cylinder block 31, avoiding the direct collision between the piston 33 and the cylinder block 31, reducing the damage to the cylinder block 31, and increasing the service life of the cylinder block 31. Understandably, in other embodiments, the protective cover plate 311 may also be provided on other sides of the cylinder block 31 to provide comprehensive protection for the cylinder block 31, ensure the normal operation of the cylinder block 31, and can be specifically set according to actual use needs, which will not be specifically limited here.

[0034] Please continue to refer to Figure 1 , in an embodiment, the frame 10 includes a mounting body 11. A first through hole 111 is provided on the mounting body 11, and the buffer member 50 is slidably mounted in the first through hole 111 so that the buffer member 50 moves relative to the mounting body 11 along the first through hole 111.

[0035] In order to make the movement of the buffer 50 relative to the installation body 11 more stable, in one embodiment, a hollow column 113 is fixed on the installation body 11, and the hollow column 113 includes a hollow through hole 1131, and the hollow through hole 1131 is coaxially aligned with and connected to the first through hole 111, so that the buffer 50 is slidably installed in the hollow through hole 1131 and the first through hole 111. In other words, the buffer 50 is movably connected with the first through hole 111 and the hollow through hole 1131, so that the buffer 50 can move relative to the installation body 11 along the first through hole 111 and the hollow through hole 1131, thereby increasing the contact surface between the buffer 50 and the installation body 11, avoiding the buffer 50 from being offset during the movement, and making the movement of the buffer 50 relative to the installation body 11 more stable. Optionally, the size of the first through hole 111 and the size of the hollow through hole 1131 can be specifically set according to actual use needs, and are not specifically limited here.

[0036] It can be understood that the number and size of the hollow columns 113 and whether the hollow columns 113 are arranged on the side of the installation body 11 close to the cylinder 30 or the side away from the cylinder 30 can be specifically set according to actual use needs and are not specifically limited here.

[0037] In a specific embodiment, the hollow column 113 includes a first hollow column 1133 and a second hollow column 1135. The first hollow column 1133 is fixed to a side of the installation body 11 away from the cylinder 30, and the second hollow column 1135 is fixed to a side of the installation body 11 close to the cylinder 30. The hollow through hole 1131 of the first hollow column 1133 and the hollow through hole 1131 of the second hollow column 1135 are coaxially aligned with and connected to the first through hole 111, and the inner diameters of the hollow through holes 1131 of the first hollow column 1133 and the second hollow through holes 1131 of the second hollow column 1135 are the same as those of the first through hole 111, so that the first hollow column 1133 can be slidably installed on the first hollow column 1133. The buffer 50 of the hollow through hole 1131 of the first hollow column 1133, the hollow through hole 1131 of the second hollow column 1135 and the first through hole 111 can better fit with the inner space of the first hollow column 1133, the second hollow column 1135 and the first through hole 111, so that the buffer 50 can move relative to the installation body 11 along the hollow through hole 1131 of the first hollow column 1133, the hollow through hole 1131 of the second hollow column 1135 and the first through hole 111, thereby increasing the contact surface between the buffer 50 and the installation body 11, avoiding the buffer 50 from deflecting or shaking during the movement, and making the movement of the buffer 50 relative to the installation body 11 more stable. It can be understood that in other embodiments, the first hollow column 1133 can also be fixed to a side of the installation body 11 close to the cylinder 30, and the second hollow column 1135 can also be fixed to a side of the installation body 11 away from the cylinder 30, which is not specifically limited here.

[0038] In order to reduce the friction between the hollow column 113 and the buffer member 50, in one embodiment, a copper sleeve 70 is disposed in the hollow through hole 1131 of the hollow column 113. Since the copper sleeve 70 has high hardness and wear resistance, the inner peripheral surface of the copper sleeve 70 abuts against the outer peripheral surface of the buffer member 50, and the outer peripheral surface of the copper sleeve 70 abuts against the inner peripheral surface of the hollow through hole 1131. The setting of the copper sleeve 70 avoids the direct contact between the inner peripheral surface of the hollow column 113 and the outer peripheral surface of the buffer member 50, and prevents the buffer member 50 from rubbing against the inner peripheral surface of the hollow column 113 when moving relative to the mounting body 11 within the hollow column 113, thereby causing wear. Further, in one embodiment, in order to make it easier for the buffer member 50 to move relative to the mounting body 11, lubricating oil or the like can be coated on the inner peripheral surface of the copper sleeve 70 to reduce the sliding friction force between the buffer member 50 and the copper sleeve 70, which is beneficial to the movement of the buffer member 50 relative to the copper sleeve 70.

[0039] Please continue to refer to Figure 1 , in one embodiment, the buffer member 50 includes a buffer rod 51 and a buffer piece 53. The buffer rod 51 is slidably disposed in the hollow through hole 1131 and the first through hole 111. One end of the buffer rod 51 close to the cylinder block 31 is fixedly connected to the buffer piece 53. Since the area of the buffer piece 53 is larger than the cross-sectional areas of the first through hole 111 and the hollow through hole 1131, when the buffer rod 51 moves relative to the mounting body 11 under the impact force of the shuttle or the reaction force of the air pressure, it will not break away from the mounting body 11, ensuring the normal operation of the buffer 100. Optionally, the shape and size of the buffer piece 53 can be specifically set according to actual use needs, and no specific limitation is made here.

[0040] Please continue to refer to Figure 1 , in one embodiment, the frame 10 further includes a base 13 and a connecting member 15. That is to say, compared with the above embodiment, in this embodiment, the frame 10 includes a mounting body 11, a base 13 and a connecting member 15. The cylinder block 31 is fixedly mounted on the base 13, and the connecting member 15 connects the mounting body 11 and the base 13. Optionally, the outer dimensions of the mounting body 11 and the base 13 and the length of the connecting member 15 can be specifically set according to actual use needs, and no specific limitation is made here.

[0041] Specifically, a first mounting hole is provided at the bottom of the cylinder block 31, and the base 13 is provided with a second through hole matching the first mounting hole. The mounting screw passes through the first mounting hole and is screwed into the second through hole to fix the cylinder block 31 on the base 13. Optionally, the number of the first mounting hole and the second through hole can be specifically set according to the actual use scenario, and no specific limitation is made here.

[0042] The connecting member 15 includes a connecting rod 151 and two fastening members 153. One end of the connecting rod 151 is fixedly connected to the mounting body 11, and the base 13 is movably mounted on the other end of the connecting rod 151. Specifically, a third through hole is further provided on the base 13, the connecting rod 151 passes through the third through hole, and the two fastening members 153 are respectively arranged on opposite sides of the base 13, and the fastening member 153 can be screwed relative to the connecting rod 151 to be locked or released. For example, when the fastening member 153 is screwed relative to the connecting rod 151 to be locked, the base 13 is fixedly connected to the connecting rod 151, preventing shaking during the operation of the air cylinder 30; when the fastening member 153 is screwed relative to the connecting rod 151 to be released, the base 13 can move along the connecting rod 151, so as to adjust the specific position of the base 13 on the connecting rod 151, and thus adjust the distance between the air cylinder 30 and the buffer member 50 to achieve the best buffer braking effect.

[0043] Wherein, the connecting rod 151 and the fastening member 153 can be threadedly connected. Specifically, in one embodiment, threads are provided on the outer peripheral surface of the connecting rod 151 and the inner peripheral surface of the fastening member 153, and the connecting rod 151 and the fastening member 153 are threadedly connected. By rotating the fastening member 153, the specific position of the fastening member 153 on the connecting rod 151 is adjusted, so as to adjust the specific position of the base 13 on the connecting rod 151, and further adjust the distance between the mounting body 11 and the base 13. The distance between the mounting body 11 and the base 13 can be specifically set according to the impact force generated by the shuttle or other factors, and no specific limitation is made here. Optionally, the number of the connecting rods 151 and the number of the fastening members 153 fixed to the base 13 in cooperation with one connecting rod 151 can be specifically set according to the usage requirements, and no specific limitation is made here.

[0044] In a specific embodiment, the air cylinder 30, the mounting body 11 and the base 13 are all cube-shaped. There are 4 connecting rods 151, and there are two fastening members 153 fixed to the base 13 in cooperation with one connecting rod 151. Specifically, the 4 connecting rods 151 are respectively arranged at the four ends of the cube-shaped base 13. The base 13 and the mounting body 11 are connected by the 4 connecting rods 151, making the connection between the mounting body 11 and the base 13 more stable; the air cylinder 30 is arranged in the exact middle of the side of the base 13 facing the mounting body 11, making the force on the base 13 uniform and avoiding cracking due to uneven force, which affects the normal use of the air cylinder 30.

[0045] In other embodiments, the connecting member 15 is a connecting lead screw, which fixedly connects the mounting body 11 and the base 13 through the connecting lead screw. Specifically, the connecting lead screw includes an adjusting screw and a nut. The adjusting screw is fixed on the mounting body 11, and the outer peripheral surface of the adjusting screw and the inner peripheral surface of the nut are provided with mutually matching threads. The nut is fixed to the base 13 and is mounted at one end of the adjusting screw. It can be understood that the nut may not be provided, and a threaded hole matching the adjusting screw may be provided on the base 13, so that the adjusting screw and the threaded hole cooperate to form a lead screw connection.

[0046] In one embodiment, the connecting lead screw can be a ball screw, so as to further reduce the friction between the adjusting screw and the mounting body 11 and / or the base 13, thereby reducing wear and increasing the service life. Specifically, the connecting lead screw further includes balls disposed between the adjusting screw and the nut. The balls can rotate and circulate. When the rotating nut adjusts its position on the adjusting screw to adjust the specific position of the base 13 on the adjusting screw, the friction between the nut and the adjusting screw is rolling friction, reducing the frictional resistance when adjusting the position of the nut, thereby reducing the wear between the nut and the adjusting screw and increasing the service life.

[0047] In the above embodiment, the buffer member of the buffer of the loom of the present application receives an impact force from the shuttle rod. The buffer member moves relative to the frame body. As the buffer member moves, the buffer member collides with the piston rod, causing the piston rod and the buffer member to move in the same direction and at the same speed, thereby pushing the piston in the cylinder body to move. Since the gas is easily compressed under the action of an external force, the pressure generated by the gas increases. As the moving stroke of the piston relative to the cylinder body increases, the gas in the cylinder body is compressed, causing the pressure in the cylinder body to increase. Thus, the buffer member pushed by the piston rod receives a reaction force, and the reaction force is transmitted to the shuttle rod through the buffer member, preventing the shuttle rod from moving outward, and the reaction force is transmitted to the shuttle through the pirn on the shuttle rod to effectively consume the remaining energy of the shuttle, so that the shuttle is buffered and stopped within a short time.

[0048] On the other hand of the present application, the present application further provides a shuttle box. The shuttle box includes the buffer 100 in any of the above embodiments. Since the buffer 100 has the effects of preventing the shuttle rod from moving and consuming the remaining energy of the shuttle, so that the shuttle is buffered and stopped within a short time, the shuttle box provided by the present application also has the corresponding above effects.

[0049] In another aspect of the present application, the present application further provides a loom, which includes a shuttle rod, a picking peg fixed on the shuttle rod, and a shuttle that moves by being impacted by the shuttle rod. The shuttle rod includes a driving end for impacting the shuttle. Among them, the loom further includes the buffer 100 in any of the above embodiments. The driving end of the shuttle is located between the buffer member 50 of the buffer 100 and the shuttle, and the buffer member 50 is disposed opposite to the driving end of the shuttle rod. The driving end of the shuttle rod can move to push the buffer member 50 to move relative to the frame 10. The buffer 100 has the effect of preventing the shuttle rod from moving and consuming the remaining energy of the shuttle, so that the shuttle is buffered and stopped in a short time. The loom provided by the present application also has the corresponding above-mentioned effect.

[0050] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
