Description

Technical Field

[0001] This invention relates to the field of accessories technology for circular knitting machines, and specifically to a belt mounting and adjustment bracket for circular knitting machines. Background Technology

[0002] A circular knitting machine belt mounting bracket is an accessory designed to guide the winding of belts on a circular knitting machine during normal operation. It includes a frame, with a first and third rotating mechanism on the left side and a second rotating mechanism on the right side. All three mechanisms are pulley assemblies mounted on the frame, coordinating to facilitate the winding and installation of two belts. In existing technology, the first and third rotating mechanisms employ... Figure 8 The structure shown, that is, the structure of the third rotating mechanism, is the same as the structure of the first rotating mechanism. Since the left side of the third rotating mechanism also has an aluminum disc used in circular knitting machines to drive the belt, and the belt used in circular knitting machines is a circular belt with its two ends connected together, in order to continue winding and mounting the belt that is already mounted on the aluminum disc onto the third rotating mechanism, as shown... Figure 7 As shown, the first support shaft on the third rotating mechanism needs to be removed before the belt can continue to be wound and installed. This operation is time-consuming and results in low efficiency in the winding and installation of the belt.

[0003] Typically, the belt mounting frame of a circular knitting machine is also equipped with an adjustment device for adjusting the specific installation position of the second rotating mechanism.

[0004] Regarding the positioning mechanism and belt adjusting frame disclosed in Chinese Patent Application No. 201521077640.9, the positioning mechanism includes a housing, a control gate, and a gear. The control gate is rotatably connected to the upper end of the housing, and the gear is rotatably placed inside the housing. A first fastener is provided inside the housing, located on one side of the gear, and can engage with the gear. Rotating the control gate can push the first fastener to release the gear. The first fastener includes a first fastener body and a first steel wire spring. The first fastener body is rotatably connected to the inner wall of the housing. One end of the first steel wire spring is fitted onto the first fastener body, and the other end abuts against the housing. The first steel wire spring can drive the first fastener body to rotate and engage the gear. This positioning mechanism is an adjustment device used in the prior art for adjusting the specific installation position of the second rotating mechanism in a circular knitting machine belt mounting frame.

[0005] The belt adjustment frame includes the positioning mechanism, the adjusting pulley assembly, the slide rod, the fixed pulley assembly, and the fixed seat. One end of the slide rod is fixedly connected to the fixed seat, and the fixed pulley assembly is fixedly placed on the slide rod near the fixed seat. A toothed row is provided on one side of the slide rod, and the positioning mechanism engages with the toothed row of the slide rod to adjust the tension of the machine belt. The adjusting pulley assembly is connected to the positioning mechanism.

[0006] This positioning mechanism has the following drawbacks:

[0007] 1. Short service life: Due to the small tooth profile of the gear and gear rack and their constant meshing, and the vibration of the belt pulley assembly during transmission, the teeth on the gear and gear rack wear down. The first fastener body also experiences significant wear due to its contact with the gear teeth. Furthermore, each adjustment requires rotating the gear to mesh with the gear rack, especially when significantly adjusting the installation position of the adjusting pulley assembly. This meshing transmission causes wear on the teeth of the gear and gear rack. All these factors combined result in the gear and gear rack losing their meshing effect after a period of use, making it difficult for the positioning mechanism to effectively adjust the installation position of the adjusting pulley assembly, thus leading to a short service life.

[0008] 2. Complex structure. Summary of the Invention

[0009] To address the aforementioned problems, this invention provides a belt installation and adjustment frame for a circular knitting machine that has a long service life, a simple structure, and improves belt winding and installation efficiency.

[0010] To achieve the above objectives, this invention discloses a belt mounting and adjustment frame for a circular knitting machine, comprising a frame, a first rotating mechanism and a third rotating mechanism on the left side of the frame, and a second rotating mechanism on the right side of the frame. The first rotating mechanism, the second rotating mechanism, and the third rotating mechanism work together to facilitate the installation of at least one belt. The right side of the frame also has at least one set of adjustment devices for adjusting the installation position of the second rotating mechanism. The adjustment device includes a housing that can slide to the right under the action of a first external force and is fitted onto the frame and fixedly connected to one end of the second rotating mechanism. The housing has a cavity, and a first elastic element is provided at the right end of the housing inside the cavity. A first positioning plate is provided at the right end of the first elastic element. Both the first elastic element and the first positioning plate are fitted onto the frame. Under the action of the first elastic element, the first positioning plate simultaneously abuts against the frame and the right end of the housing of the cavity.

[0011] A further improvement is that the adjustment device also includes an actuating element that can slide left and right through the front right side of the housing and is used to actuate the first positioning plate when subjected to a second external force.

[0012] A further improvement is that the adjustment device also includes a tensioning mechanism disposed on the housing at the left side of the cavity for releasing the first positioning plate from the abutting state with the frame so as to further drive the housing to slide according to a set stroke.

[0013] A further improvement is made to the tensioning mechanism, which includes a second elastic element disposed on the left end of the housing of the cavity. A second positioning plate is disposed on the right end of the second elastic element. Both the second elastic element and the second positioning plate are sleeved on the frame. The right end of the second positioning plate is abutted against the housing inside the cavity and is in a vertical position. The housing is also provided with a handle for actuating the second positioning plate to tilt it and abut against the frame, and after abutting, it can drive the housing to move to the right by a set stroke.

[0014] A further improvement is that both the first and second elastic elements are springs.

[0015] A further improvement is that the second rotating mechanism includes two second support shafts arranged opposite to each other on the right side of the frame and in a cantilever state, a second roller rotatably mounted on each of the second support shafts, and a mounting base that can slide left and right and is fixedly connected to each of the second support shafts. The two cantilever ends of the two second support shafts are pre-set with a second interval space to facilitate the belt to be wound around the second roller.

[0016] A further improvement is that the mounting base includes a first mounting block that can slide left and right and has a third through groove at its upper or lower end to accommodate the frame, and a mounting plate disposed at one end of the first mounting block to block the opening of the third through groove. The first mounting block is also provided with a first set screw hole at the other end of the third through groove. The first mounting block is locked or unlocked with the frame by a set screw disposed in the first set screw hole through a threaded connection. The other end of the mounting plate is connected to the second support shaft, and the left end of the first mounting block is fixedly connected to the right end of the housing.

[0017] A further improvement is that the mounting base includes a second mounting block that can slide left and right and is sleeved on the frame. The second mounting block has a fourth through groove that passes through both ends of the second mounting block and is used to accommodate the frame. The upper or lower part of the second mounting block is also provided with a second set screw hole that communicates with the fourth through groove. The second mounting block is locked or unlocked to the frame by a set screw that is threaded into the second set screw hole. The other end of the second mounting block located in the second set screw hole is connected to the second support shaft. The left end of the second mounting block is fixedly connected to the right end of the housing.

[0018] A further improvement is that the third rotating mechanism includes two third support shafts arranged opposite to each other on the left side of the frame and in a cantilever state, and a third roller that is rotatable and respectively arranged on each of the third support shafts. The two cantilever ends of the two third support shafts are pre-set with a third interval space to facilitate the belt to be wound around and installed on the third roller.

[0019] A further improvement is that the third rotating mechanism includes a fourth support shaft located on the left side of the frame and in a cantilevered state, and two rotatable third rollers spaced apart on the fourth support shaft. The cantilever end of the fourth support shaft and the wall end of the frame are pre-set with a third interval space to facilitate belt winding and installation.

[0020] A further improvement is that the first rotating mechanism includes a first support shaft spanning the upper and lower ends of the left side of the frame and two first rollers that are rotatable and spaced apart on the first support shaft.

[0021] A further improvement is that the frame includes an upper slide bar and a lower slide bar spaced apart vertically. The upper slide bar and the lower slide bar are connected by a fifth support shaft that passes through the right end of the upper slide bar and the right end of the lower slide bar, respectively. The lower slide bar is fixedly connected to the circular knitting machine.

[0022] A further improvement is that the left side of the frame also includes two connecting pieces, one above the other, respectively disposed at the lower end of the upper slide rod and the upper end of the lower slide rod. The front ends of the two connecting pieces are connected to one end of each of the third support shafts, and the rear ends of the two connecting pieces are connected to both ends of the first support shaft.

[0023] A further improvement is that the two connecting pieces are connected by a connecting rod that spans across the two connecting pieces and provides auxiliary support to the front ends of the two connecting pieces.

[0024] A further improvement is that the frame also includes a mounting bracket fixed to the left end of the sliding rod.

[0025] The beneficial effects of the present invention after adopting the above technical solution are as follows:

[0026] 1. The adjustment device effectively utilizes the principle of relative motion to lock the second positioning plate with the upper slide rod or lower slide rod via the handle. Further rotation of the handle allows the housing to slide to the right relative to the second positioning plate, thereby releasing the lock between the first positioning plate and the upper slide rod or lower slide rod. This allows the first elastic element and the first positioning plate to slide to the right under the action of the parallel vertical rod of the housing. After releasing the handle, the second positioning plate is unlocked from the upper slide rod or lower slide rod, and the second positioning plate will slide to the right under the action of the second elastic element, which is in a compressed state. The relative motion throughout the process is smooth and will not shorten the service life of the adjustment device due to wear, thus extending the service life of the adjustment device.

[0027] 2. The structures of the various parts used in this invention are relatively simple and easy to assemble.

[0028] 3. The second and third interval spaces facilitate the installation of belts on the circular knitting machine, which helps to improve the efficiency of belt installation.

[0029] 4. The connecting rod not only helps to separate the belts passing on its front and rear sides, avoiding interference between the belts due to possible belt loosening during operation, but the connecting rod can also work together with the fifth support shaft to maintain stable support for the upper sliding rod and the lower sliding rod.

[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and should not be used to limit the scope of protection of the present invention.

[0042] refer to Figures 1 to 10 As shown, the technical solution adopted in this specific embodiment is:

[0043] A belt adjustment frame for a circular knitting machine includes a frame 1. A first rotating mechanism 2 and a third rotating mechanism 4 are arranged on the left side of the frame 1, and a second rotating mechanism 3 is arranged on the right side of the frame 1. The first rotating mechanism 2, the second rotating mechanism 3, and the third rotating mechanism 4 work together to facilitate the winding and installation of upper and lower belts. The right side of the frame 1 also includes two sets of adjustment devices 5 for adjusting the installation position of the second rotating mechanism 3. Each adjustment device 5 includes a component that can slide to the right under a first external force and is sleeved on the frame 1. The second rotating mechanism 3 is fixedly connected to a housing 51 at one end. The housing 51 has a cavity 6. A first elastic element 52 is provided at the right end of the housing 51 at the center of the cavity 6. The first elastic element 52 is also sleeved on the frame 1. A first positioning plate 53 is provided at the right end of the first elastic element 52. The first positioning plate 53 has a first through groove 7. The first positioning plate 53 is sleeved on the frame 1 through the first through groove 7. Under the action of the first elastic element 52, the first positioning plate 53 simultaneously interacts with the frame 1. The right end housing protrusion 511 of the frame 1 and the cavity 6 are abutted and connected and are in an inclined state. At this time, because the first through groove 7 end of the first positioning plate 53 is abutted and locked with the frame 1, the first positioning plate 53 will remain locked with the frame 1. In this state, when the housing 51 is subjected to a force F1 in the left direction, because the right end housing protrusion 511 of the cavity 6 abuts against the first positioning plate 53, the housing 51 will not be able to move to the left. When the housing 51 is subjected to a force F2 in the right direction, because... The first elastic element 52 has compressibility and delayed elastic force transmission. The protruding part 511 of the right end of the housing 51 of the cavity 6 will first slide to the right and release the first positioning plate 53 from its abutting state, so that the first positioning plate 53 and the frame 1 are in a relatively relaxed and unlocked state. The housing 51 can slide to the right under the action of the rightward force F2. The sliding of the housing 51 will simultaneously drive the second rotating mechanism 3 to slide to the right. The first positioning plate 53 slides to the right under the elastic force of the first elastic element 52. In this embodiment, the housing 51 in the middle of the cavity 6 consists of two vertical rods 512 arranged parallel in the front and back directions. The right ends of the two vertical rods 512 are abutted and connected to the left end of the first elastic element 52. The surface of the frame 1 is smooth. The first external force includes a leftward force F1 and a rightward force F2. The belt used in this invention is a belt with both ends connected together to form a circular shape.

[0044] The adjustment device 5 also includes an actuating element 54 that can slide left and right through the front right side of the housing 51 and is used to actuate the first positioning plate 53 when subjected to a second external force. Figure 2As shown, the second external force is a force F acting to the left. When the actuator 54 is subjected to the force F acting to the left, it can slide to the left to actuate the first positioning plate 53 so that it is in a vertical state and disengages from the abutting connection with the frame 1. At this time, the locking relationship between the first positioning plate 53 and the frame 1 will be released. In this state, when the leftward force F1 or the rightward force F2 is applied to the housing 51, the installation position of the housing 51 and the second rotating mechanism 3 can be adjusted significantly.

[0045] The adjustment device 5 further includes a tensioning mechanism 55 disposed on the housing 51 at the left side of the cavity 6, for releasing the first positioning plate 53 from the abutting state with the frame 1 so as to further drive the housing 51 to slide according to a set stroke. The tensioning mechanism 55 includes a second elastic element 551 disposed on the left end of the housing 51 of the cavity 6. The second elastic element 551 is also sleeved on the frame 1. A second positioning plate 552 is disposed on the right end of the second elastic element 551. A second through groove is disposed on the second positioning plate 552. The second positioning plate 552 is sleeved on the frame 1 through the second through groove. The right end of the second positioning plate 552 is abutted and connected to two parallel vertical rods 512 in the middle of the cavity 6 and is in a vertical state. The housing 51 is also provided with a rotatable handle 553 for actuating the second positioning plate 552 to tilt it and abut against the frame 1, and after abutting, it can drive the housing 51 to slide to the right according to a set stroke.

[0046] When the handle 553 is rotated clockwise, it will actuate the second positioning plate 552, causing it to tilt and abut against the frame 1. At this time, because the second slot end of the second positioning plate 552 is locked against the frame 1, the second positioning plate 552 will remain locked to the frame 1. When the handle 553 is rotated further clockwise, since the second positioning plate 552 remains stationary, the continued rotation of the handle 553 will cause the right end housing 51 protrusion 511 of the cavity 6, which was originally abutted against the right end of the first positioning plate 53, to slide to the right, thus releasing the locking relationship between the first positioning plate 53 and the frame 1. When the handle 553 continues to rotate, This will cause the housing 51 to slide slightly to the right according to a set stroke. The set stroke is related to the horizontal distance between the rotation center of the handle 553 and the second positioning plate 552 when they are in a vertical state, the tilt angle of the second positioning plate 552 when it is locked to the frame 1, and the angle at which the handle 553 continues to rotate when the second positioning plate 552 is locked and stationary. Since the housing 51 slides to the right relative to the second positioning plate 552, the left end of the housing 51 of the cavity 6 will compress the second elastic element 551. When the handle 553 is released, the second positioning plate 552 will slide to the right under the elastic force of the second elastic element 551. Both the first elastic element 52 and the second elastic element 551 are springs.

[0047] The second rotating mechanism 3 includes two second support shafts 31 facing each other on the right side of the frame 1 and in a cantilever state, a second roller 32 rotatably mounted on each of the second support shafts 31, and a mounting base 33 that can slide left and right and is fixedly connected to each of the second support shafts 31. The two cantilever ends of the two second support shafts 31 are pre-formed with a second interval space 8 to facilitate the belt to be wound around the second roller 32.

[0048] like Figure 1As shown, there are two mounting bases 33, located on the upper and lower sides of the right side of the frame 1 respectively. Each mounting base 33 includes a first mounting block 331 that can slide left and right and has a third through groove 9 at the upper or lower end to accommodate the frame 1, and a mounting plate 332 disposed at one end of the first mounting block 331 to block the opening of the third through groove 9. The first mounting block 331 is also provided with a first set screw hole 10 at the other end of the third through groove 9. The first mounting block 331 is locked or unlocked with the frame 1 by a set screw disposed in the first set screw hole 10 through a threaded connection. The other end of the mounting plate 332 is connected to the second support shaft 31. The left end of the first mounting block 331 is fixedly connected to the right end of the housing 51. Each set of adjustment devices 5 can independently control the specific installation position of the mounting base 33 on the same side, thereby adjusting the position of the second support shaft 31 and the second roller 32 to tension the belt.

[0049] The third rotating mechanism 4 includes two third support shafts 41 that are arranged opposite to each other on the left side of the frame 1 and are in a cantilever state, and a third roller 42 that is rotatable and is respectively arranged on each of the third support shafts 41. The two cantilever ends of the two third support shafts 41 are pre-set with a third interval space 43 to facilitate the belt to be wound around and installed on the third roller 42.

[0050] The first rotating mechanism 2 includes a first support shaft 21 spanning the upper and lower ends of the left side of the frame 1 and two first rollers 22 that are rotatable and spaced apart on the first support shaft 21.

[0051] Because the belt used in this invention is a circular belt with its two ends connected together, and it needs to be used in conjunction with an aluminum disc 23 located on the left side of the third rotating mechanism 4 during belt winding and installation, such as... Figure 7 As shown, the aluminum disc 23 is used to drive the belt. The third interval space 43 in the third rotating mechanism 4 of the present invention is beneficial to the use of the circular knitting machine. After the belt is wound around the aluminum disc 23, it can pass through the third interval space 43 and continue to be wound around the third roller 42. This not only avoids the trouble of removing the first support shaft 21 on the third rotating mechanism 4 when the third rotating mechanism 4 adopts the structure of the first rotating mechanism 2, but also helps to improve the winding and installation efficiency of the belt. Figure 8 The structure shown is that the third rotating mechanism 4 adopts the structural form of the first rotating mechanism 2.

[0052] The first roller 22, the second roller 32 and the third roller 42 have the same structure. The first roller 22, the second roller 32 and the third roller 42 appear in pairs, which is beneficial for the present invention to use two belts at the same time. The upper or lower end surfaces of the first roller 22, the second roller 32 and the third roller 42 located on the same side of the frame 1 are on the same horizontal plane.

[0053] The frame 1 includes an upper sliding rod 11 and a lower sliding rod 12 spaced apart vertically. The upper sliding rod 11 and the lower sliding rod 12 are connected by a fifth support shaft 13 passing through the right end of the upper sliding rod 11 and the right end of the lower sliding rod 12, respectively. The left end of the lower sliding rod 12 is fixedly connected to the circular knitting machine on the left side. The fifth support shaft 13 helps to maintain stable support for the upper sliding rod 11 and the lower sliding rod 12. The first rotating mechanism 2 and the third rotating mechanism 4 are both located on the left side of the upper sliding rod 11 and the lower sliding rod 12, and the second rotating mechanism 3 is located on the right side of the upper sliding rod 11 and the lower sliding rod 12. The housing 51, the first elastic element 52, and the second elastic element 53 are all sleeved on the upper sliding rod 11 or the lower sliding rod 12. The first positioning plate 53 and the second positioning plate 552 are respectively sleeved on the upper sliding rod 11 or the lower sliding rod 12 through the first through groove 7 and the second through groove.

[0054] The left side of the frame 1 also includes two connecting pieces 15, one upper and one lower, which are respectively set at the lower end of the upper slide rod 11 and the upper end of the lower slide rod 12 by connecting bolts. The front ends of the two connecting pieces 15 are connected to one end of each of the third support shafts 41, and the rear ends of the two connecting pieces 15 are connected to both ends of the first support shaft 21. The two connecting pieces 15 are arranged in parallel and form a certain angle with the upper slide rod 11 or the lower slide rod 12. This angle can be installed and set according to the actual use.

[0055] The two connecting pieces 15 are connected by a connecting rod 16 that spans the two connecting pieces 15 and provides auxiliary support to the front end of the two connecting pieces 15 and separates the belt located between the first roller 22 and the third roller 42 to prevent interference due to possible loosening of the belt during operation. The connecting rod 16 can also work together with the fifth support shaft 13 to maintain stable support for the upper sliding rod 11 and the lower sliding rod 12.

[0056] The frame 1 also includes a mounting bracket 14 fixed to the left end of the sliding rod 12, which can fix the present invention at the corresponding position of the left circular knitting machine.

[0057] Based on the technical solution of the above embodiments, the third rotating mechanism 4 can also adopt the following structure, including a fourth support shaft 401 disposed on the left side of the frame 1 and in a cantilever state, and two third rollers 42 rotatable and spaced apart on the fourth support shaft 401. A third space 43 is pre-set between the cantilever end of the fourth support shaft 401 and the lower end of the upper slide rod 11 or the upper end of the lower slide rod 12 to facilitate belt winding and installation. Figure 9 or Figure 10 As shown. The second rotating mechanism 3 can also adopt this structure, but in this case, only one set of the adjustment device 5 set on the upper slide rod 11 or the lower slide rod 12 is needed.

[0058] The mounting base 33 can also adopt the following structure, including a second mounting block 3301 that can slide left and right and is sleeved on the upper sliding rod 11 or the lower sliding rod 12. The second mounting block 3301 has a fourth through groove 24 that passes through both ends of the second mounting block 3301 and is used to accommodate the upper sliding rod 11 or the lower sliding rod 12. The upper or lower part of the second mounting block 3301 is also provided with a second set screw hole 25 communicating with the fourth through groove 24. The second mounting block 3301 is locked or unlocked with the upper sliding rod 11 or the lower sliding rod 12 by a set screw threaded into the second set screw hole 25. The other end of the second mounting block 3301 located in the second set screw hole 25 is connected to the second support shaft 31. The left end of the second mounting block 3301 is fixedly connected to the right end of the housing 51. Figure 1 and Figure 5 As shown.

[0059] Basic principle:

[0060] 1. Belt winding and installation principle: As shown in Figure 7, a circular belt is first passed between the first roller 22 and the third roller 42 and then wound around the second roller 32 on one side of the second rotating mechanism 3 through the second gap space 8. At this time, one end of the belt is also wound around the first roller 22 on the first rotating mechanism 2, which is at the same horizontal position as the second roller 32. Then, the other end of the belt is pulled out from one side of the connecting rod 16 and wound around the aluminum disc 23. Subsequently, the belt is passed through the third gap space 43 of the third rotating mechanism 4 and enters the other side of the connecting rod 16 and wound around the third roller 42, which is at the same horizontal position as the first roller 22 and the second roller 32.

[0061] 2. Working principle of the adjustment device: When it is necessary to significantly adjust the installation position of the housing 51 and the mounting base 33 according to the belt length, a leftward force F can be applied to the actuator 54 to release the first positioning plate 53 from the upper sliding rod 11 or lower sliding rod 12 of the frame 1. Then, continue to apply a leftward force F1 or a rightward force F2 to the housing 51 to significantly adjust the installation position of the housing 51 and the mounting base 33. When it is necessary to slightly tension the belt, the handle 553 can be rotated to move the housing 51 and the mounting base 33 slightly to the right according to the set stroke to tension the belt on the second roller 32. After the position of the mounting base 33 is adjusted, the set screws on the first mounting block 331 or the second mounting block 3301 can be tightened to keep the mounting base 33 locked to the upper sliding rod 11 or lower sliding rod 12 of the frame 1.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall under the protection of the claims.
