Description

Technical Field

[0001] This utility model relates to the technical field of wire mesh weaving equipment, specifically a wire pressing mechanism for a stainless steel wire mesh weaving machine. Background Technology

[0002] The stainless steel wire used in vibrating screen mesh weaving is very fine. If a wire breaks during the weaving process, it is necessary to find the broken and tangled wire ends one by one and reconnect them before weaving can continue, which will waste a lot of time and manpower and resources.

[0003] Publication number CN218080181U discloses a wire pressing mechanism for a stainless steel screen weaving machine for battery materials. This mechanism uses a pressure roller with a rubber layer to press the stainless steel wire between a guide roller and the rubber layer. The flexibility of the rubber layer holds the stainless steel wire in place, preventing it from becoming tangled after breakage, thus saving repair time and improving work efficiency. However, this patent still has the following problems in practical use:

[0004] A pressure roller with a rubber layer presses against a guide roller, allowing the stainless steel wire to pass between the rubber layer and the guide roller. The flexibility of the rubber layer holds the stainless steel wire in place, preventing it from becoming tangled after breakage, saving repair time and improving work efficiency. However, when a broken stainless steel wire comes into contact with the rubber layer, the broken wire may embed or scratch the rubber sleeve. Even if it is not completely broken, local elasticity failure may lead to a decrease in clamping performance, requiring regular inspection and early replacement. In existing technologies, the installation of the pressure roller is mostly completed by the fit between bolts and nuts. However, when replacing the rubber layer on the pressure roller, the pressure roller needs to be disassembled. Frequent disassembly causes wear on the threads between the bolts and nuts, which can lead to instability after the pressure roller is installed.

[0005] A wire pressing mechanism for a stainless steel screen weaving machine is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a wire pressing mechanism for a stainless steel screen weaving machine, in order to solve the problems mentioned in the background art. Currently, stainless steel wire is pressed between the rubber layer and the guide roller by a pressure roller with a rubber layer. The flexibility of the rubber layer is used to press the stainless steel wire, preventing it from becoming tangled after breakage, saving repair time and improving work efficiency. However, when the broken stainless steel wire comes into contact with the rubber layer, the broken wire may embed or scratch the rubber sleeve. Even if it is not completely broken, the local elasticity may fail, resulting in a decrease in pressing performance. Regular inspection and early replacement are required. In the prior art, the installation of the pressing roller is mostly completed by the cooperation of bolts and nuts. However, when the rubber layer on the pressing roller is replaced, the pressing roller needs to be disassembled. Frequent disassembly causes wear on the thread texture between the bolts and nuts, which can lead to instability of the pressing roller after installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire pressing mechanism for a stainless steel screen weaving machine, comprising a concave block, wherein a screw is connected through the middle of the top surface of the concave block;

[0008] A bearing seat is rotatably connected to the bottom surface of the screw, a clamping plate is fixedly connected to the bottom surface of the bearing seat, a connecting plate is fixedly connected to one side of the top surface of the concave block, a sliding rod is connected through the inside of the connecting plate, and nuts are threaded on both sides of the sliding rod, and the nuts are fitted and connected to the connecting plate.

[0009] Also includes:

[0010] A fixing frame is symmetrically mounted on one side surface of the sliding rod, and an installation component is provided inside the fixing frame;

[0011] The mounting components include a connecting sleeve that is connected through the mounting bracket;

[0012] The top surface of the connecting sleeve is rotatably connected to a rotating block.

[0013] Preferably, a rotating rod is fixedly connected to the middle of the bottom surface of the rotating block, and a rotating plate is fixedly connected to the bottom surface of the rotating rod.

[0014] Preferably, a pressing block is attached to the bottom surface of the rotating plate, and a clamping rod is fixedly connected to the middle of the bottom surface of the pressing block.

[0015] Preferably, a return spring is sleeved on the surface of the clamping rod, the top surface of the return spring is fixedly connected to the pressing block, and the bottom surface of the return spring is fixedly connected to the connecting sleeve.

[0016] Preferably, the locking rod is connected through the connecting sleeve.

[0017] Preferably, a placement groove is provided on one side of the sliding rod, a connecting rod is movably connected inside the placement groove, and a pressure roller is fixedly connected to the side of the connecting rod away from the placement groove, and a rubber sleeve is provided on the surface of the pressure roller.

[0018] Preferably, the connecting rod has symmetrical slots on both sides, and the slots engage with the connecting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the wire pressing mechanism for a stainless steel screen weaving machine, by setting up installation components, allows for convenient disassembly of the pressing roller, thereby facilitating the replacement of the rubber sleeve on the pressing roller, which can reduce the downtime of the weaving machine to a certain extent. The specific details are as follows:

[0020] 1. By setting up the installation components, when the pressure roller needs to be disassembled, rotating the rotating block causes the rotating rod to rotate, which in turn causes the rotating plate to rotate, thus squeezing the extrusion block. The top of the extrusion block is irregularly shaped, divided into a high point and a low point, each with an arc-shaped limiting groove. This ensures that when the rotating plate rotates to its low point, its bottom is positioned within the arc-shaped limiting groove. Under the action of the return spring, the extrusion block rises, simultaneously causing the clamping rod to rise as well. After the clamping rod rises to a certain distance, it separates from the slot, allowing the pressure roller to be removed and the rubber sleeve on it to be replaced. During installation, the connecting rod on the pressure roller is placed in the slot on the sliding rod. Then, the rotating block is rotated again, causing it to drive the rotating plate. As the rotating plate moves from a low position to a high position, it presses against the extrusion block, causing it to descend. This descent of the extrusion block causes the clamping rod to descend as well, engaging the clamping rod with the slot, thus completing the installation of the pressure roller.

[0021] 2. By setting up a connecting plate, a sliding rod, and nuts, when the height of the pressure roller needs to be adjusted, the nuts on both sides of the sliding rod are rotated so that they are no longer in contact with the connecting plate. This allows the sliding rod to slide within the groove opened in the connecting plate. After the sliding rod has slid to a certain position, the nuts are tightened, causing the nuts on both sides of the sliding rod to press against the connecting plate, thereby increasing the friction between the nuts and the connecting plate. At least four nuts are used. This ensures that the friction between the multiple nuts and the sliding rod, after the sliding rod is connected to the pressure roller, is greater than the weight of the sliding rod and the pressure roller, thus reducing the possibility of the sliding rod and the pressure roller falling off.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a wire pressing mechanism for a stainless steel screen weaving machine, including a concave block 1, with a screw 2 penetrating through the middle of the top surface of the concave block 1; a bearing seat 3 is rotatably connected to the bottom surface of the screw 2, a pressing plate 4 is fixedly connected to the bottom surface of the bearing seat 3, a connecting plate 5 is fixedly connected to one side of the top surface of the concave block 1, a sliding rod 6 is penetrating through the inside of the connecting plate 5, and nuts 7 are threaded on both sides of the sliding rod 6, with the nuts 7 fitting against the connecting plate 5; it also includes: a fixing frame 8 symmetrically installed on one side surface of the sliding rod 6, with an installation component 9 inside the fixing frame 8; wherein, the installation component 9 includes a connecting sleeve 901 penetrating through the fixing frame 8; wherein, a rotating block 902 is rotatably connected to the top surface of the connecting sleeve 901, such as Figure 1-5As shown, by setting the installation component 9, the pressure roller 12 can be easily disassembled, allowing for the replacement of the rubber sleeve 13 on the pressure roller 12. This reduces the downtime of the weaving machine to some extent. Simultaneously, the cooperation between the concave block 1, screw 2, bearing seat 3, and pressure plate 4 allows the entire device to be installed on the front crossbeam of the weaving machine. Furthermore, by setting the connecting plate 5, sliding rod 6, and nut 7, when the height of the pressure roller 12 needs to be adjusted, rotating the nuts 7 on both sides of the sliding rod 6 removes the nuts 7 from contact with the connecting plate 5, allowing the sliding rod to... 6 can slide inside the groove opened in the connecting plate 5. After sliding the sliding rod 6 to a certain position, the nuts 7 are tightened, so that the nuts 7 on both sides of the sliding rod 6 press against the connecting plate 5, thereby increasing the friction between the nuts 7 and the connecting plate 5. At the same time, there are no less than four nuts 7. This ensures that after the sliding rod 6 is connected to the pressure roller 12, the friction between the multiple nuts 7 and the connecting plate 5 is greater than the weight between the sliding rod 6 and the pressure roller 12, thereby reducing the occurrence of the sliding rod 6 and the pressure roller 12 falling off.

[0030] A rotating rod 903 is fixedly connected to the bottom surface of the rotating block 902. A rotating plate 904 is fixedly connected to the bottom surface of the rotating rod 903. A pressing block 905 is attached to the bottom surface of the rotating plate 904. A locking rod 906 is fixedly connected to the bottom surface of the pressing block 905. A return spring 907 is sleeved on the surface of the locking rod 906. The top surface of the return spring 907 is fixedly connected to the pressing block 905, and the bottom surface of the return spring 907 is fixedly connected to the connecting sleeve 901. The locking rod 906 and the connecting sleeve 901 are connected through each other. Figure 3 , 4 As shown, when the pressure roller 12 needs to be disassembled, the rotating block 902 is rotated, which drives the rotating rod 903 to rotate. The rotation of the rotating rod 903 drives the rotating plate 904 to rotate, which in turn squeezes the extrusion block 905. The top of the extrusion block 905 is irregularly shaped, divided into a high point and a low point. Arc-shaped limiting grooves are provided at the high point and the low point respectively. When the rotating plate 904 rotates to the low point, the bottom of the rotating plate 904 is located inside the arc-shaped limiting groove. Under the action of the return spring 907, the extrusion block 905 rises, which drives the clamping rod 906 to rise. After the clamping rod 906 rises to a certain distance, it separates from the clamping groove 14, so that the pressure roller 12 can be disassembled and the rubber sleeve 13 on the pressure roller 12 can be replaced.

[0031] A placement groove 10 is provided on one side of the sliding rod 6. A connecting rod 11 is movably connected inside the placement groove 10. A pressure roller 12 is fixedly connected to the side of the connecting rod 11 away from the placement groove 10. A rubber sleeve 13 is fitted on the surface of the pressure roller 12. Through the cooperation between the pressure roller 12 and the rubber sleeve 13, the stainless steel wire is pressed onto the stainless steel wire guide roller of the weaving machine, so that the stainless steel wire passes between the rubber sleeve 13 and the guide roller. The flexibility of the rubber sleeve 13 is used to press the stainless steel wire, preventing the stainless steel wire from becoming tangled after breaking. At the same time, the rubber sleeve 13 is made of nitrile rubber, which has stronger tear resistance, thereby increasing the service life of the rubber sleeve 13.

[0032] The connecting rod 11 has symmetrical slots 14 on both sides, which engage with the locking rod 906. Figure 3 As shown, when installing the pressure roller 12, after placing the connecting rod 11 on the pressure roller 12 into the placement groove 10 on the sliding rod 6, the rotating block 902 is rotated again, causing the rotating block 902 to drive the rotating plate 904. When the rotating plate 904 moves from a low position to a high position, it will squeeze the pressing block 905, causing the pressing block 905 to descend. The descent of the pressing block 905 will drive the locking rod 906 to descend, thereby engaging the locking rod 906 with the locking groove 14, thus completing the installation of the pressure roller 12.

[0033] Working principle: Before using the wire pressing mechanism of this stainless steel screen weaving machine, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, by first setting the installation component 9, when it is necessary to disassemble the pressure roller 12, the rotating block 902 is rotated, causing the rotating rod 903 to rotate. The rotation of the rotating rod 903 causes the rotating plate 904 to rotate, thereby causing the rotating plate 904 to squeeze the pressing block 905. At the same time, the top of the pressing block 905 is irregularly shaped, divided into a high point and a low point, and arc-shaped limiting grooves are opened at the high point and the low point respectively. This ensures that when the rotating plate 904 rotates to the low point, the bottom of the rotating plate 904 is located inside the arc-shaped limiting groove. Under the action of the return spring 907, the pressing block 905 rises, which in turn drives the clamping rod 906 to rise. After the clamping rod 906 rises to a certain distance, it separates from the slot 14, allowing the pressure roller 12 to be removed and the rubber sleeve 13 on the pressure roller 12 to be replaced. Simultaneously, when installing the pressure roller 12, the connecting rod 11 on the pressure roller 12 is placed in the placement slot 10 on the sliding rod 6. Then, the rotating block 902 is rotated again, causing the rotating block 902 to drive the rotating plate 904. As the rotating plate 904 moves from a lower position to a higher position, it squeezes the pressing block 905, causing the pressing block 905 to descend. This descent of the pressing block 905 causes the clamping rod 906 to descend, thus engaging the clamping rod 906 with the slot 14, completing the installation of the pressure roller 12.

[0034] Secondly, by setting up a connecting plate 5, a sliding rod 6, and nuts 7, when the height of the pressure roller 12 needs to be adjusted, the nuts 7 on both sides of the sliding rod 6 are rotated so that the nuts 7 are no longer in contact with the connecting plate 5, allowing the sliding rod 6 to slide inside the groove opened in the connecting plate 5. After the sliding rod 6 has slid to a certain position, the nuts 7 are tightened, causing the nuts 7 on both sides of the sliding rod 6 to press against the connecting plate 5, thereby increasing the friction between the nuts 7 and the connecting plate 5. At the same time, there are no fewer than four nuts 7. This ensures that the friction between the multiple nuts 7 and the sliding rod 6 after the sliding rod 6 is connected to the pressure roller 12 is greater than the weight between the sliding rod 6 and the pressure roller 12, thereby reducing the possibility of the sliding rod 6 and the pressure roller 12 falling off.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
