Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of coiled material dust removal equipment, and particularly relates to a tension adjusting assembly with stroke release structure. BACKGROUND

[0002] The tension adjusting assembly in the coiled material dust removal mechanism is a device for controlling the tension of the coiled material during transmission. The tension adjusting assembly of the coiled material dust removal mechanism is prone to sudden tension change during adjustment. Since there is no stroke release mechanism for buffering, when the tension adjusting assembly is adjusted in response to the transmission of the coiled material, the tension will suddenly increase or decrease, which seriously threatens the integrity of the coiled material. For example, thin plastic film coiled material is prone to tearing, and paper is prone to wrinkling,

[0003] The conventional countermeasures have limited effectiveness and significant drawbacks. The tension can be stabilized to a certain extent by optimizing the material and design of the adjusting roller, such as selecting high-friction stable materials and adjusting the roller diameter and shape. However, the use of new materials is costly and the processing of special shapes is complex. Adjusting the parameters of the driving device to enhance the stability of power output may result in energy waste and may also affect the service life of the equipment due to overloading.

[0021] Please refer to Figures 1 to 2 As a first embodiment of the present application: two U-shaped grooves 101 are formed on the upper side surface of the mounting frame 100 and symmetrically recessed downward, the coiled material roller 110 is rotatably clamped in the U-shaped groove 101, the outer side surface of the coiled material roller 110 is wound with the coiled material body 111 for dust removal, and the adjusting assembly one and the adjusting assembly two 300 are matched in structure.

[0022] The adjusting assembly one comprises: an adjusting roller one 250 and a rotating shaft rod one 251, one rotating shaft rod one 251 is rotatably installed at each end of the adjusting roller one 250, and the rotating shaft rod one 251 is slidably clamped on the inner wall surface of the mounting frame 100 through a sliding groove 201, the adjusting assembly two 300 comprises: an adjusting roller two and a rotating shaft rod two, and the mounting manner of the adjusting assembly one is matched with the mounting manner of the adjusting assembly two 300.

[0023] The mounting height of the adjusting assembly one is greater than the height of the adjusting assembly two 300, and one mounting plate two 220 is installed at each end of the adjusting assembly one and the adjusting assembly two 300.

[0024] In use, the user first winds the web body 111 to be dedusted on the outer surface of the web roller 110, and then rotates and clamps the web roller 110 inside the U-shaped groove 101, at this time, the user can guide the side surface of the wound web body 111 out, and make it wrap around the outer surface of the adjusting roller one 250, the adjusting roller two and the rotating roller 140, make the web body 111 located on the lower side surface of the adjusting roller one 250, and then on the upper side surface of the adjusting roller two, and then make the web body 111 located on the lower side surface of a rotating roller 140 and the upper side surface of a rotating roller 140, and finally make the web body 111 pass above the air bellow 130, and then the user sets the winding device to connect the side surface of the web body 111 with the winding device, at this time, the user can start the winding device (the winding device is prior art, and the specific working principle and structure are not described here), and make the web body 111 transport and move through the adjusting roller one 250, the adjusting roller two and the rotating roller 140.

[0025] When tension adjustment is needed, the user can simultaneously start the electric push rods on both side surfaces of the mounting frame 100, make the telescopic rods of the electric push rods rise, thereby driving the mounting plate two 220 connected with the electric push rods to rise, thereby driving the adjusting roller one 250 and the adjusting roller two connected with the mounting plate two 220 to rise, and similarly, make the telescopic rods of the electric push rods descend, thereby making the adjusting roller one 250 and the adjusting roller two descend, and adjusting the distance between the adjusting roller one 250 and the adjusting roller two, thereby achieving the effect of tension adjustment. Since the adjusting assembly one and the adjusting assembly two 300 jointly act in use, the tension at different positions of the web can be adjusted, and the tension at different positions may be different, the adjusting assembly one and the adjusting assembly two 300 can independently adjust the tension of the web at the respective positions, and then work cooperatively to more accurately control the tension of the entire web within a suitable range.

[0026] Please refer to Figures 1 to 2 , as a second embodiment of the utility model: the lower side of the mounting plate two 220 is provided with a mounting plate three 230 through the mounting frame 100, and the mounting plate three 230 and the mounting plate two 220 are provided with an electric push rod, and the electric push rod is electrically connected with the control box 120 on the outer surface of the mounting frame 100 through wires.

[0027] The upper side of the mounting plate two 220 is provided with the mounting plate one 210 through the mounting frame 100, and the helical spring 240 is arranged between the mounting plate one 210 and the mounting plate two 220; the dust removal device comprises a wind box 130 and a blowing pipe 131; the inner wall of the mounting frame 100 is provided with the wind box 130; the upper side surface of the wind box 130 is uniformly provided with a plurality of blowing pipes 131; the wind box 130 is connected with a wind supply device through a hose; when the coiled material body 111 passes above the wind box 130 and the blowing pipe 131, the external wind supply device is started to blow the lower side surface of the coiled material body through the blowing pipe 131; after the dust removal of one side surface is completed, the dust removal of the other side can be realized through direction operation.

[0028] When the tension is adjusted through the adjusting assembly one and the adjusting assembly two 300, the mounting plate two 220 is lifted up and down through the electric push rod; when the electric push rod drives the mounting plate two 220 to lift up and down, the helical spring 240 on the upper side surface of the mounting plate two 220 is stretched, so that the helical spring 240 is stretched up and down between the mounting plate two 220 and the mounting plate three 230 according to the state of the electric push rod; at this time, the helical spring 240 plays a role of stroke buffering; when the helical spring 240 is subjected to an external force, elastic deformation is generated according to Hooke's law (f=kx), wherein f is the external force (the strength of the electric push rod), k is the stiffness coefficient of the spring, and x is the deformation amount of the spring; when the tension is adjusted through the adjusting assembly one and the adjusting assembly two 300, the tension of the coiled material is increased, the adjusting roller one 250 and the adjusting roller two are subjected to an outward force, and the helical spring 240 connected with the adjusting roller one 250 and the adjusting roller two is compressed and stretched; at this time, the elastic force of the helical spring 240 resists the external force, so that the displacement speed of the adjusting roller is slowed down; when the helical spring 240 is restored, the slow rebound is also realized according to the stroke of the electric push rod, and the adjusting roller one 250 and the adjusting roller two are not affected by the restoring elastic force of the helical spring 240; since the tension may be suddenly changed due to various factors in the coiled material transmission process, when the adjusting assembly one and the adjusting assembly two 300 directly respond to the tension change without the buffering assembly 200, the tension may be suddenly too large, and the buffering assembly 200 can buffer the tension impact in the adjusting process through the above steps, so that the adjustment of the coiled material tension by the adjusting assembly one and the adjusting assembly two 300 is more gentle, and the coiled material body 111 is prevented from being damaged, such as tearing, breaking or wrinkling.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
