Description

Technical Field

[0001] This utility model relates to the field of tensioning device technology, and in particular to a tensioning device for molybdenum wire production. Background Technology

[0002] Molybdenum wire is an important metallic material, mainly used in electronics, metallurgy, aerospace and medical fields. The production process involves multiple steps, including raw material preparation, molybdenum wire preparation, cleaning and sintering. To facilitate production, a tensioning device is usually used to control the tension of the molybdenum wire during transmission and adjust the transmission state of the molybdenum wire according to requirements.

[0003] A search revealed a tensioning device for molybdenum wire production, with publication number CN221140672U. This device includes a double-column frame, a steering plate, and a connecting assembly. The double-column frame has two sets of shafts movably connected to the steering plate, and guide wheel assemblies are movably connected to the outer sides of the two sets of steering plates. A connecting assembly is horizontally and movably installed on the inner sides of the two sets of steering plates. The connecting assembly includes a horizontal plate, a vertical plate, and a movable shaft. A vertical plate is horizontally positioned in the middle of the horizontal plate, and movable shafts are respectively provided at the contact points between the horizontal plate and the two sets of steering plates for shaft connection. A lifting air rod is vertically installed on the bottom wall of the horizontal plate and the top of the double-column frame. This invention addresses the problem that in most existing technologies, molybdenum wire is transmitted via rollers. However, when the tension of the molybdenum wire needs adjustment, it is achieved by manually adjusting the position of the rollers. This adjustment is prone to over-adjustment, instability, and damage to the molybdenum wire, and the accuracy of the adjustment cannot be controlled.

[0004] The device in the disclosed patent requires manual rotation of the helical shaft to adjust the position of the pulleys during use. It cannot keep the two pulleys sliding synchronously, which affects the conveying effect of molybdenum wire and requires stopping the machine for adjustment, thus affecting the production efficiency of molybdenum wire. Utility Model Content

[0005] In response to the technical problem in existing patents that require manual rotation of the helical shaft to adjust the position of the pulleys during use, making it impossible to maintain synchronous sliding of the two pulleys, thus affecting the conveying effect of molybdenum wire and requiring machine stoppage for adjustment, thereby affecting the production efficiency of molybdenum wire, this utility model provides a tensioning device for molybdenum wire production.

[0006] The technical solution adopted in this utility model is: a tensioning device for molybdenum wire production, comprising:

[0007] The tensioning mechanism includes a base, two support bars rotatably fitted on one side of the base, a mounting plate slidably fitted on one side of the support bars, a threaded rod rotatably fitted on one side of the support bars and threadedly fitted to the mounting plate, and a drive mechanism disposed on the upper side of the base for driving the two support bars to rotate.

[0008] The adjustment mechanism includes a support plate fixed to the upper side of the base, a slider elastically slidably engaged with the upper side of the support plate, a first synchronous wheel rotatably engaged with one side of the slider, a second synchronous wheel fixed to one end of the threaded rod, a synchronous belt drivingly engaged between the first synchronous wheel and the two second synchronous wheels, and a first servo motor disposed on one side of the slider for driving the first synchronous wheel. The output shaft of the first servo motor passes through the slider and is fixedly connected to the first synchronous wheel.

[0009] Furthermore, a guide wheel is rotatably fitted on one side of the mounting plate, a bearing is embedded on one side of the support bar, a smooth surface is provided at one end of the threaded rod, and one end of the threaded rod is fixed in the bearing.

[0010] Furthermore, the mounting plate has a polygonal protrusion on one side, and the support bar has a polygonal groove on one side. One end of the polygonal protrusion is slidably fitted in the polygonal groove, and the threaded rod is threadedly fitted with the polygonal protrusion.

[0011] Furthermore, the drive mechanism includes an electric push rod fixed to the base, a connecting bar fixed to the output end of the electric push rod, and a transmission bar rotatably engaged with the connecting bar on one side of the support bar.

[0012] Furthermore, the upper side of the support plate is provided with a cross-shaped opening groove, the slider is a cross-shaped block structure, the slider slides in the cross-shaped opening groove, a spring damper is fixed on the bottom surface of the inner wall of the cross-shaped opening groove, and the slider is fixed on the upper side of the spring damper.

[0013] The beneficial effects of this utility model are:

[0014] By setting a tensioning mechanism, the electric push rod drives the connecting bar to slide. The connecting bar pulls the support bar and guide wheel to rotate synchronously through the transmission bar, causing the guide wheel to move up or down, thus tensioning or slackling the molybdenum wire. This replaces the straight up-and-down movement that lowers the horizontal height, making it less prone to vibration during adjustment and preventing the molybdenum wire from detaching from the guide wheel.

[0015] By setting an adjustment mechanism, when the guide wheel is adjusted, the second synchronous wheel drives the first synchronous wheel and the slider to move up or down through the synchronous belt. The spring damper compresses or extends to keep the first and second synchronous wheels and the synchronous belt engaged. The first servo motor drives the first synchronous wheel to drive the two second synchronous wheels to rotate synchronously through the synchronous belt, which in turn drives the threaded rod to rotate and drives the mounting plate and guide wheel to slide horizontally. This allows the two guide wheels to slide horizontally synchronously to guide the molybdenum wire delivery, which avoids stopping the machine to adjust the two guide wheels sequentially and affecting the molybdenum wire delivery.

[0025] To address the problems existing in the background art, this application proposes the following technical solution:

[0026] A tensioning device for molybdenum wire production, comprising:

[0027] Tensioning mechanism 1 includes a base 101, two support bars 102 rotatably fitted on one side of the base 101, a mounting plate 103 slidably fitted on one side of the support bars 102, a threaded rod 104 rotatably fitted on one side of the support bars 102 and threadedly fitted with the mounting plate 103, and a drive mechanism located on the upper side of the base 101 for driving the two support bars 102 to rotate.

[0028] The adjustment mechanism 2 includes a support plate 201 fixed to the upper side of the base 101, a slider 202 elastically slidingly engaged with the upper side of the support plate 201, a first synchronous wheel 203 rotatably engaged with one side of the slider 202, a second synchronous wheel 204 fixed to one end of the threaded rod 104, a synchronous belt 205 transmissionally engaged between the first synchronous wheel 203 and the two second synchronous wheels 204, and a first servo motor 206 located on one side of the slider 202 for driving the first synchronous wheel 203. The output shaft of the first servo motor 206 passes through the slider 202 and is fixedly connected to the first synchronous wheel 203.

[0029] Furthermore, a guide wheel 105 is rotatably fitted on one side of the mounting plate 103, a bearing is embedded on one side of the support bar 102, and a smooth surface is provided at one end of the threaded rod 104, with one end of the threaded rod 104 fixed inside the bearing.

[0030] Furthermore, one side of the mounting plate 103 is provided with a polygonal protrusion 106, and one side of the support bar 102 is provided with a polygonal groove 107. One end of the polygonal protrusion 106 is slidably fitted in the polygonal groove 107, and the threaded rod 104 is threadedly fitted with the polygonal protrusion 106.

[0031] Furthermore, the drive mechanism includes an electric push rod 108 fixed to the base 101, a connecting bar 109 fixed to the output end of the electric push rod 108, and a transmission bar 110 rotatably engaged with the connecting bar 109 and the support bar 102 on one side.

[0032] Furthermore, the upper side of the support plate 201 is provided with a cross-shaped opening groove 207, the slider 202 is a cross-shaped block structure, the slider 202 slides in the cross-shaped opening groove 207, the bottom surface of the inner wall of the cross-shaped opening groove 207 is fixed with a spring damper 208, and the slider 202 is fixed on the upper side of the spring damper 208.

[0033] Working principle: When the electric push rod 108 is activated, it drives the connecting bar 109 to slide. The connecting bar 109 pulls the support bar 102, guide wheel 105, and second synchronous wheel 204 to rotate synchronously via the transmission bar 110. This causes the guide wheel 105 to move up or down, thus tensioning or slackening the molybdenum wire. The second synchronous wheel 204 drives the first synchronous wheel 203 and slider 202 to move up or down via the synchronous belt 205. The spring damper 208 compresses or extends to keep the first synchronous wheel 203 and the second synchronous wheel 204 engaged with the synchronous belt 205. The first servo motor 206 is turned on, driving the first synchronous pulley 203 to rotate synchronously through the synchronous belt 205, which in turn drives the two second synchronous pulleys 204 to rotate synchronously. The threaded rod 104 rotates, and the threaded rod 104 is threadedly engaged with the polygonal protrusion 106. The polygonal protrusion 106 is guided to slide horizontally under the guidance of the polygonal groove 107, which in turn drives the mounting plate 103 and the guide wheel 105 to slide horizontally. This allows the two guide wheels 105 to slide horizontally synchronously and guide the molybdenum wire to be transported, which avoids the need to stop the machine and adjust the two guide wheels 105 sequentially, thus affecting the molybdenum wire transport.
