In addition, in one embodiment, as shown in fig. 3 and fig. 6, a dimension of an end of the protrusion 211 away from the elastic element 220 is smaller than a dimension of an end of the protrusion 211 close to the elastic element 220, so as to facilitate the supporting seat 310 to align with the protrusion 211 and further to be sleeved outside the protrusion 211.

In addition, as shown in fig. 3 and 5, the connecting shaft 312 includes a first shaft body 314 and a second shaft body 315, an outer diameter of the first shaft body 314 is smaller than an outer diameter of the second shaft body 315, so that a step surface 316 is formed between the first shaft body 314 and the second shaft body 315, and the bearing 320 and the wheel body 330 are sequentially fitted over the first shaft body 314. The connecting shaft 312 is axially provided with a second threaded hole 313, as shown in fig. 5, the second threaded fastener 350 can be matched with the second threaded hole 313, the gasket 360 is located between the second threaded fastener 350 and the connecting shaft 312, one side of the bearing 320 abuts against the gasket 360, and the other side abuts against the step surface 316, so that the bearing 320 can be firmly sleeved on the connecting shaft 312 by the second threaded fastener 350 and the gasket 360.

In addition, as shown in fig. 3 and 6, the roller further includes a third threaded fastener 400 having a hollow interior, both inner and outer walls of the third threaded fastener 400 are threaded, the third threaded fastener 400 is threaded at an end of the main housing 100 away from the rolling assembly 300, and the adjusting member 230 is threaded in the third threaded fastener 400. It is understood that in other embodiments, the third threaded fastener 400 may not be provided and the adjusting member 230 may be directly threaded to the inner wall of the main housing 100.

In addition, as shown in fig. 6, the long hole 120 on the main housing 100 has a first end 121 and a second end 122 that are oppositely disposed, the first end 121 is far away from the third threaded fastener 400, the second end 122 is close to the third threaded fastener 400, the adjusting assembly 200 further includes a baffle 250, the baffle 250 is located between the elastic member 220 and the adjusting member 230 and is used for providing a pressing support for the adjusting member 230, the elastic member 220 is compressed between the baffle 250 and the sliding rod 210, the sliding rod 210 slides in a direction far away from the elastic member 220 under the elastic restoring force of the elastic member 220, but when the limiting member 240 abuts against the first end 121 of the long hole 120, the sliding of the sliding rod 210 in a direction far away from the elastic member 220 is limited.

As shown in fig. 1, when the roller is operated, the main housing 100 is held, and the adhesive tape is firmly adhered to the adhesive surface 600 by the rolling force of the roller body 330. When the rolling force of the roller is greater than the elastic restoring force of the elastic member 220, the elastic member 220 is further compressed, and the limiting member 240 slides toward the second end 122 of the long hole 120; when the rolling force of the roller is too large and is much greater than the elastic restoring force of the elastic member 220, the elastic member 220 is compressed severely, and the limiting member 240 abuts against the second end 122 of the slot 120, thereby preventing the elastic member 220 from being damaged by compression. In the use of the roller, the limiting member 240 may just start to slide towards the second end 122 of the long hole 120, or the limiting member 240 may slide a certain distance towards the second end 122 of the long hole 120, as a normal use state of the roller.

In one embodiment, the adjusting member 230 is an adjusting screw, and the adjusting screw is rotated to move along the length direction of the main housing 100, thereby adjusting the compression amount of the elastic member 220. When the roller is in use, the rolling force of the roller is greater than the elastic restoring force of the elastic member 220, and the limiting member 240 slides away from the first end 121 of the slot 120, so that the rolling force of the rolling assembly 300 during operation can be adjusted by rotating the adjusting screw to adjust the compression amount of the elastic member 220. In one embodiment, before the roller is used, the adjusting screw is rotated to make the elastic restoring force of the elastic member 220 reach a set value or a set range, and at this time, the force value can be measured by using an elastic force meter, and the rolling force of the roller is approximately equal to the force value when the limiting member 240 starts to slide towards the second end 122 of the long hole 120 during the use of the roller. In addition, in one embodiment, when the elastic member 220 is a spring, according to hooke's law, the elastic restoring force of the elastic member 220 can be calculated according to the elastic coefficient and the compression amount of the spring, and at this time, force value scales can be set beside the long hole 120 of the main housing 100 to facilitate observation and control of the rolling force of the roller. In another embodiment, a digital display may be further disposed on the main housing 100 of the roller, and the calculated elastic restoring force is visually displayed according to the elastic coefficient and the compression amount of the spring, so as to facilitate observation and control of the rolling force of the roller.

In one embodiment, in order to prevent the adhesive surface 600 of the adhesive tape from being damaged due to the excessive rolling force of the roller, as shown in fig. 1 to 3, a friction wheel 500 is further disposed on one end of the main housing 100 close to the rolling assembly 300, a gap is formed between the friction wheel 500 and the rolling assembly 300, an axle of the friction wheel 500 is parallel to an axle of the wheel body 330 of the rolling assembly 300, and an anti-slip structure is disposed on an outer surface of the friction wheel 500. As shown in fig. 1 and 3, when the roller rolls the adhesive surface 600 of the adhesive tape, the rolling force of the roller is greater than the elastic restoring force of the elastic member 220, the elastic member 220 is further compressed, the main housing 100 and the friction wheel 500 move toward the direction close to the rolling assembly 300, and when the rolling force of the roller is too large, the friction wheel 500 abuts against the wheel body 330 of the rolling assembly 300 to limit the rotation of the wheel body 330, so as to remind the user well and prevent the adhesive surface 600 of the adhesive tape from being damaged by applying too large rolling force to the roller.

In one embodiment, as shown in fig. 1, the roller may be applied to a rubberizing production line, the adhesive surface 600 of the tape may slide upwards or downwards along with the belt, the main housing 100 of the roller is fixed, the wheel body 330 of the rolling assembly 300 abuts against and rolls the adhesive surface 600 of the tape, the limiting member 240 just starts to slide towards the second end 122 of the long hole 120, or the limiting member 240 slides towards the second end 122 of the long hole 120 for a certain distance, so that by observing the position of the limiting member 240 in the long hole 120 of the main housing 100, it is possible to know whether the rolling force of the roller on the adhesive surface 600 of the tape is too large or too small, and the use is simple and reliable.

In addition, in one embodiment, as shown in fig. 4, the total length L of the roller is 120mm, the total width W1 is 17.5mm, and the width W2 of the roller body 330 in the rolling assembly 300 is 2.5mm, so that the whole roller is small in size and convenient to carry, and in addition, the ultra-narrow design of the width of the roller body 330 can be flexibly applied to narrow adhesive surfaces.

The roller of the present invention adjusts the position of the adjusting member 230 to move along the length direction of the main housing 100 by properly designing the shapes and the connection relationship of the main housing 100, the adjusting assembly 200 and the rolling assembly 300, thereby adjusting the compression amount of the elastic member 220. When the roller is in use, the rolling force of the roller is greater than the elastic restoring force of the elastic member 220, and the limiting member 240 slides away from the first end 121 of the slot 120, so that the rolling force of the rolling assembly 300 during operation can be adjusted by adjusting the position of the adjusting member 230 and adjusting the compression amount of the elastic member 220. In one embodiment, before the roller is used, the position of the adjusting member 230 is adjusted in advance so that the elastic restoring force of the elastic member 220 reaches a set value or a set range, and at this time, the force value can be measured by using an elastic force meter, and the rolling force of the roller is approximately equal to the force value when the limiting member 240 starts to slide towards the second end 122 of the long hole 120 during the use of the roller. By observing the position of the limiting member 240 in the elongated hole 120 of the main housing 100, it is possible to know whether the rolling force of the roller is too large or too small, and the use is simple and reliable. In addition, the roller can be flexibly applied to a rubberizing production line and a relatively narrow bonding surface.
