Description
Technical Field
[0001] This utility model relates to the field of heald frame technology, and in particular to a quick locking device for the heald frame guide groove base. Background Technology
[0002] A heald frame guide groove base is a key component in textile machinery used for installing and positioning heald frames. It is usually made of metal and has a specific groove structure to accommodate the guide rails on both sides of the heald frame, ensuring that the heald frame moves along a fixed trajectory when it is raised and lowered, reducing swaying and offset. Its design must meet the requirements of high strength and wear resistance to adapt to the high-speed operating environment of the loom. Some bases are also equipped with quick locking devices to facilitate the installation, disassembly and adjustment of the heald frame, improve equipment maintenance efficiency, and ensure the stability of the weaving process and the quality of the fabric.
[0003] The heald frame typically achieves reciprocating lifting motion in cam-driven and linkage-driven mechanisms. Its two side guide rails are embedded in the guide groove base, and the up-and-down reciprocating motion is completed by the power transmitted by the mechanism. For example, in a cam mechanism, the cam's profile curve is converted into the up-and-down reciprocating motion of the heald frame through the rotational motion of the cam.
[0004] However, existing heald frame lifting mechanisms, such as cam and linkage structures, are prone to significant wear during long-term reciprocating lifting, resulting in differences in lifting height and affecting the accuracy requirements of the heald frame when operating in textile machines. Furthermore, for example, the cam mechanism has a protruding bump on one side, which makes the lifting effect relatively slow. Utility Model Content
[0005] The purpose of this utility model is to provide a quick locking device for the heald frame guide groove base to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: including a support structure, a heald frame body, and a transmission mechanism;
[0007] The support structure is used to provide a support foundation for the overall device. The support structure includes a support plate. Two L-shaped plates are arranged opposite each other at the left and right ends of the support plate along the central axis of the support plate. The surfaces of the L-shaped plates are provided with grooves.
[0008] The main body of the heald frame is located inside the support structure and can be slidable. It includes two slide rails and two racks. The backs of the two slide rails and two racks are fixedly installed on the front and rear sides of the main body of the heald frame, respectively, and each slide rail is slidably connected to a corresponding slide groove.
[0009] The transmission mechanism is used for lifting the main body of the heald frame. It includes two transmission rods, both ends of which are fixedly mounted with gears. Each upper and lower corresponding gear is fitted with a chain on its outside. The two chains are meshed with a rack inside each other for transmission. A first pulley and a second pulley are fixedly mounted on the outer wall of one row of gears. A synchronous belt is slidably connected inside the first pulley and the second pulley. A motor is fixedly connected to the outer wall of the second pulley.
[0010] Preferably, two guide slot plates and two sleeves are fixedly installed on one side of the support plate, and the two chains are slidably connected to the inside of one guide slot plate, and the two transmission rods are slidably connected to one sleeve.
[0011] Preferably, one of the chains has a locking mechanism on its exterior.
[0012] Preferably, the support structure further includes a mounting plate, which is fixedly mounted on top of the support structure.
[0013] Preferably, the locking mechanism includes a connecting rod, with locking pins movably connected to the upper and lower ends of the connecting rod, and movable blocks movably connected to the center of each locking pin, with the tails of each movable block fixedly installed on one side of the mounting plate.
[0014] Prior to this, one end of each of the two locking pins engages with the upper and lower grooves of one of the chains, and a cylinder is fixedly connected to one side of the connecting rod. The bottom of the cylinder is fixedly mounted on a support platform on one side of the mounting plate.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] In this utility model, a support plate of the support structure connects a guide groove plate, a sleeve, and an L-shaped plate. The L-shaped plate slide groove is adapted to the slide rail of the heald frame body to achieve installation guidance and limitation. In the transmission mechanism, the motor is driven by multiple stages of transmission through pulleys, synchronous belts, gears, and chains, so that the chain circulates and drives the heald frame body to lift and lower through meshing with the rack. This linkage mode ensures stable lifting and lowering, adapts to textile working conditions, improves the smoothness of the production process, meets the needs of frequent movement of the heald frame, and avoids damage to the heald frame caused by the lifting components, unlike lifting components which have poor effect on the reciprocating lifting and lowering of the heald frame body.
[0017] In this utility model, a supporting structure, a heald frame body, a transmission mechanism, and a locking mechanism work together. The mounting plate of the supporting structure supports the locking mechanism, and the supporting plate and other components form a frame. The L-shaped plate slide groove is adapted to and limited by the slide rail of the heald frame body. In the transmission mechanism, the motor drives the chain via pulleys, synchronous belts, and gears, which meshes with the rack to drive the heald frame body to rise and fall. When locking, the cylinder pushes the connecting rod to make the locking pin engage with the chain groove. When unlocking, the cylinder reverses its action to release. This mode is stable and efficient, adaptable to textile working conditions, reliable in locking, highly adaptable to components, improves efficiency, and meets production needs.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0027] Example 1: Refer to Figure 1 - Figure 4 As shown: In this embodiment, a quick locking device for the heald frame guide groove base is included, comprising a support structure 1, a heald frame body 2, and a transmission mechanism 3;
[0028] Support structure 1 provides a support base for the overall device, including a support plate 101. Two guide groove plates 102 and two sleeves 104 are fixedly installed on one side of the support plate 101. Figure 2 Two sleeves 104 are arranged opposite each other along the first direction of the transverse axis of the support plate 101, and two guide groove plates 102 are arranged opposite each other perpendicular to the first direction. An L-shaped plate 103 is fixedly installed on one side of each of the two guide groove plates 102, and a sliding groove is opened at one end of each of the two L-shaped plates 103.
[0029] The main body 2 of the heald frame is located inside the support structure 1 and includes two slide rails 201 and two racks 202. The back of the two slide rails 201 is fixedly installed on the front side of the main body 2 of the heald frame, and each slide rail 201 is slidably connected to the slide groove of an L-shaped plate 103. The back of the two racks 202 is fixedly installed on the rear side of the main body 2 of the heald frame.
[0030] The transmission mechanism 3 is used for lifting the main body 2 of the heald frame. It includes two transmission rods 301, with gears 302 fixedly installed at both ends of the two transmission rods 301. Each upper and lower gear 302 is fitted with a chain 303 on its outer side, and the two chains 303 are slidably connected to the inside of a guide slot plate 102. The inside of each chain 303 is meshed with a rack 202. A first pulley 304 and a second pulley 305 are fixedly installed on the outer wall of one row of gears 302 (e.g., ...). Figure 4 A row of gears 302 refers to the upper and lower ends of the chain 303, which are parallel to the central axis of the transmission rod 301 and respectively equipped with a first pulley 304 and a second pulley 305. The first pulley 304 and the second pulley 305 are internally slidably connected to a synchronous belt 306, and the outer wall of the second pulley 305 is fixedly connected to a motor 307.
[0031] The overall effect of this embodiment is as follows: Using the support structure 1 as the basic load-bearing component, the support plate 101 securely connects the guide slot plate 102, sleeve 104, and L-shaped plate 103. The groove in the L-shaped plate 103 precisely matches the slide rail 201 of the heald frame body 2, providing installation guidance and initial positioning for the heald frame body 2, ensuring its positional stability within the support structure 1. The sleeve 104 provides stable support for the transmission rod 301 of the transmission component, ensuring effective power transmission. In the transmission mechanism 3, the motor 307 (which can be a servo motor) starts and outputs power, driving the second pulley 305 to rotate. Through the linkage of the synchronous belt 306, the first pulley 304 rotates along with it, thereby driving the connected gear 302 to rotate. When the gear 302 rotates, it causes the chain 303 sleeved on it to circulate. The chain 303 meshes with the rack 202 on the rear side of the heald frame body 2. Through this meshing transmission relationship, the chain 303... The cyclic motion is transformed into the lifting and lowering action of the heald frame body 2 along the slide rail 201 and the L-shaped plate 103 groove. The support structure 1, through the coordinated cooperation of multiple components, achieves precise positioning of the heald frame body 2, effectively ensuring the stability of the lifting process and avoiding deviation. The transmission mechanism 3 uses the motor 307 as the power source, and forms a multi-stage transmission through the first pulley 304, the second pulley 305, the synchronous belt 306, the gear 302, and the chain 303. The power transmission is stable and efficient, enabling the heald frame body 2 to complete the lifting and lowering quickly and accurately. Moreover, the meshing method of the chain 303 and the rack 202 is adapted to the complex working conditions of textile machinery, has good wear resistance and vibration resistance, can reduce the frequency of equipment maintenance, reduce the cost of use, and avoid the large friction and damage to the components caused by cam reciprocating lifting mechanisms, and also indirectly improves the efficiency of the heald frame body 2's up and down movement. This makes the components highly adaptable, fully meeting the needs of frequent heald frame movement in textile production and improving the smoothness of the overall production process.
[0032] Example 2: According to Figure 1 - Figure 6 As shown: One of the chains 303 has a locking mechanism 4 on its exterior (e.g., Figure 5 and Figure 6 As shown, after the drive component stops running, the locking mechanism 4 locks and fixes one of the chains 303, keeping the entire heald frame at the required height. The support structure 1 includes a mounting plate 105, which is fixedly installed on the top of the support structure 1 (e.g., Figure 1 and Figure 2The mounting plate 105 is a plate that is fixed to the waist of the support structure 1 and placed horizontally (installed by bolts or welding). The locking mechanism 4 includes a connecting rod 402. The upper and lower ends of the connecting rod 402 are respectively movably connected to the locking pins 403. The center of each locking pin 403 is movably connected to a movable block 404. The tails of the two movable blocks 404 are fixedly installed on one side of the mounting plate 105. One end of each locking pin 403 is engaged with the upper and lower grooves of the chain 303. A cylinder 401 is fixedly connected to one side of the connecting rod 402. The bottom of the cylinder 401 is fixedly installed on the support platform on one side of the mounting plate 105.
[0033] The overall effect achieved by the second embodiment is as follows: the supporting structure 1, the heald frame body 2, the transmission mechanism 3, and the locking mechanism 4 work together. During operation, the mounting plate 105 of the supporting structure 1 provides top support for the locking mechanism 4. The supporting plate 101 connects to components such as the guide groove plate 102 and the sleeve 104 to construct an overall supporting frame. The sliding groove of the L-shaped plate 103 is adapted to the slide rail 201 of the heald frame body 2 to realize the installation guidance and initial positioning of the heald frame body 2. In the transmission mechanism 3, the motor 307 starts... The power is transmitted to the first pulley 304 via the second pulley 305 and the synchronous belt 306, driving the gear 302 to rotate, causing the chain 303 to circulate. The chain 303 meshes with the rack 202 of the heald frame body 2, driving the heald frame body 2 to rise and fall along the slide rail 201 and the slide groove. When locking is required, the cylinder 401 of the locking mechanism 4 receives a signal and starts, pushing the connecting rod 402 to move. The connecting rod 402 drives the upper and lower locking pins 403. Because the locking pins 403 are movably connected to the movable block 404, the connection... Under the action of lever 402, one end of pin 403 precisely engages with the upper and lower grooves of chain 303. The engagement between pin 403 and the groove of chain 303 restricts the movement of chain 303, thereby locking the position of heald frame body 2. When unlocking, cylinder 401 reverses its action, pulling connecting rod 402 to disengage pin 403 from the groove of chain 303, and chain 303 regains its mobility. This linkage mode has significant advantages. The support structure 1 has multiple components working together to ensure stable lifting and lowering of heald frame body 2. The transmission mechanism 3 achieves rapid and precise lifting and lowering of heald frame body 2 through multi-stage transmission, adapting to textile working conditions. The locking mechanism 4 uses cylinder 401 to drive pin 403 to engage with chain 303, providing rapid response and reliable locking. It can stably maintain the locked state in the vibration environment of textile machinery operation, preventing displacement of heald frame body 2. The components are highly adaptable, easy to install and disassemble, convenient for debugging and maintenance, improving production efficiency, meeting the needs of frequent lifting and stable locking of heald frames in textile production, effectively shortening adjustment time, and ensuring smooth production process.
[0034] Working principle: When the quick-locking device for the heald frame guide groove base is working, the support structure 1 serves as the core support. The support plate 101 is stably connected to the guide groove plate 102, sleeve 104, L-shaped plate 103, and mounting plate 105, forming a complete support frame. The slide groove in the L-shaped plate 103 precisely matches the slide rail 201 of the heald frame body 2, providing installation guidance and initial positioning for the heald frame body 2, ensuring its stable position within the support structure 1. In the transmission mechanism 3, the motor 307 is started as the power source, and the output power is transmitted sequentially through the second pulley 305 and the synchronous belt 306 to the first pulley 304, thereby driving the gear 302 connected to it to rotate. The rotation of gear 302 causes the chain 303, which is sleeved on it, to circulate. The chain 303 meshes with the rack 202 on the rear side of the heald frame body 2. Through this meshing transmission relationship, the circulating motion of the chain 303 is converted into the lifting and lowering motion of the heald frame body 2 along the slide rail 201 and the L-shaped plate 103 groove, realizing the up and down movement of the heald frame body 2. When it is necessary to lock and fix the heald frame body 2 during the production process, the cylinder 401 of the locking mechanism 4 is activated after receiving the control signal, pushing the connecting rod 402 to move. The connecting rod 402 drives the upper and lower locking pins 403. Since the locking pins 403 and the movable block 404 are movably connected, the connecting rod... Under the action of 402, one end of the locking pin 403 can accurately engage with the upper and lower grooves of the chain 303. The meshing action between the locking pin 403 and the grooves of the chain 303 restricts the movement of the chain 303, thereby locking the position of the heald frame body 2. This ensures that it remains stable and stationary even under the vibration environment of textile machinery operation. When unlocking is required, the cylinder 401 reverses its action, pulling the connecting rod 402, causing the locking pin 403 to disengage from the groove of the chain 303. The chain 303 then regains its mobility and can continue to drive the heald frame body 2 to rise and fall. This linkage mode, in which the support structure 1, the heald frame body 2, the transmission mechanism 3, and the locking mechanism 4 work in concert, has significant advantages. The support structure 1... The coordinated operation of multiple components ensures the stability of the heald frame body 2 during lifting. The transmission mechanism 3, through multi-stage transmission, enables the heald frame body 2 to lift quickly and accurately, adapting to the complex working conditions of textile machinery. The locking mechanism 4, driven by the cylinder 401, engages the locking pin 403 with the chain 303, providing rapid response and reliable locking, preventing the heald frame body 2 from shifting. At the same time, the components are highly compatible, and installation and disassembly are convenient, facilitating equipment debugging and maintenance. This effectively improves production efficiency, meets the needs of frequent lifting and stable locking of the heald frame body 2 in textile production, shortens adjustment time, ensures the smoothness of the production process, and makes the overall production process more efficient and stable.
