Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, specifically to a roller with a limiting structure and a roller conveyor. Background Technology

[0002] Roller conveyors are common conveying equipment widely used in industrial production. Existing roller conveyors can be found in patent application number CN201621044870.X, which includes a support frame, a drive unit, a guide plate, and several rollers. All rollers are mounted inclined and parallel on the support frame, and the drive unit drives the rollers to rotate. To restrict the material conveying direction, limiting structures can be directly set at the ends of the rollers to block the material, thus limiting the material's path. However, in actual use, it is necessary to adjust the material's path according to the actual needs of the production line. The position of the limiting structure is difficult to adjust, making it difficult for the roller conveyor to adapt to adjustments in the material's travel path.

[0003] Therefore, how to adjust the position of the roller's limiting structure is a technical problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a roller with a limiting structure and a roller conveyor, thereby solving the technical problem that the position of the limiting structure of the roller cannot be adjusted in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a roller with a limiting structure, which includes:

[0007] cylindrical body;

[0008] At least one first blocking ring, the first blocking ring being sleeved on the cylinder and slidable relative to the cylinder; and

[0009] At least one first limiting member corresponding to at least one first blocking ring, the first limiting member being mounted on the first blocking ring, and the first limiting member having a first state of being connected to the cylinder to restrict the sliding of the first blocking ring relative to the cylinder, and a second state of being disengaged from the cylinder to allow the first blocking ring to slide relative to the cylinder.

[0010] In some embodiments, the first limiting member includes a first limiting pin, which can move radially along the first blocking ring and can stop at any position on its movement trajectory. By adjusting the position of the first limiting pin, the first limiting pin can press against or disengage from the cylinder, so that the first limiting member switches between the first state and the second state.

[0011] In some embodiments, the first blocking ring has a first screw hole, and the first limiting pin has a first threaded end, which is screwed into the first screw hole.

[0012] In some embodiments, there are multiple first limiting pins, and the multiple first limiting pins are arranged circumferentially along the first blocking ring.

[0013] In some embodiments, one end of the first blocking ring is formed with a convex first guide cone surface.

[0014] In some embodiments, the end of the first blocking ring away from the first guide cone surface has a first mounting portion, and the first limiting member is mounted on the first mounting portion.

[0015] In some embodiments, there are two first blocking rings, which are arranged opposite to each other.

[0016] In some embodiments, the roller with the limiting structure further includes a second blocking ring and a second limiting member. The second blocking ring is slidably disposed between two first blocking rings, and the second limiting member is mounted on the second blocking ring. The second limiting member has a third state in which it is connected to the cylinder to restrict the sliding of the second blocking ring relative to the cylinder, and a fourth state in which it is disengaged from the cylinder to allow the second blocking ring to slide relative to the cylinder.

[0017] In some embodiments, the second limiting member includes a second limiting pin, which can move radially along the second blocking ring and can stop at any position on its movement trajectory. By adjusting the position of the second limiting pin, the second limiting pin can press against or disengage from the cylinder, thereby switching the second limiting member between the third state and the fourth state.

[0018] A roller conveyor is provided, which is equipped with a plurality of rollers with the aforementioned limiting structure arranged side by side.

[0019] Compared with the prior art, the roller with a limiting structure provided by this utility model has the following advantages:

[0020] First, the first blocking ring is fitted onto the outer circumference of the cylinder, and the first limiting member is adjusted to the second state. This allows for adjustment of the position of the first blocking ring. After the position of the first blocking ring is adjusted, the first limiting member can be adjusted to the first state, thereby fixing the relative position of the first blocking ring and the cylinder. Since the relative position of the first blocking ring and the cylinder is adjustable, the movement trajectory of the workpiece on the roller conveyor can be adjusted by changing the position of the first blocking ring, thus making the roller with the limiting structure more versatile.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] To address the technical problem that the position of the limiting structure of the roller cannot be adjusted, this utility model provides a roller with a limiting structure. Since the relative position of the first blocking ring 200 and the cylinder 100 is adjustable, the first blocking ring 200 can be adjusted to plan different movement trajectories for the material to be conveyed, thereby improving the applicability of the roller with the limiting structure.

[0026] It should be noted that the roller with a limiting structure of this utility model is used in, but not limited to, roller conveyors. For ease of explanation, this utility model only uses the roller with a limiting structure applied to a roller conveyor as an example. The principle of the roller with a limiting structure applied to other types of equipment is essentially the same as that applied to roller conveyors, and will not be described in detail here.

[0027] Please see Figure 1 , Figure 1This is a schematic diagram of a structure with a limiting structure in one embodiment of the present invention. The limiting structure includes a cylindrical body 100, at least one first blocking ring 200 corresponding to each other, and at least one first limiting member 300. The first blocking ring 200 is sleeved on the cylindrical body 100 and can slide relative to the cylindrical body 100. The first limiting member 300 is installed on the first blocking ring 200, and the first limiting member 300 has a first state of connecting to the cylindrical body 100 to limit the sliding of the first blocking ring 200 relative to the cylindrical body 100, and a second state of disengaging from the cylindrical body 100 to allow the first blocking ring 200 to slide relative to the cylindrical body 100.

[0028] In this embodiment, the first blocking ring 200 is first fitted onto the outer periphery of the cylinder 100, and the first limiting member 300 is adjusted to the second state, thereby adjusting the position of the first blocking ring 200. After the position adjustment of the first blocking ring 200 is completed, the first limiting member 300 can be adjusted to the first state, thereby fixing the relative position of the first blocking ring 200 and the cylinder 100 using the first limiting member 300. Since the relative position of the first blocking ring 200 and the cylinder 100 is adjustable, the movement trajectory of the workpiece on the roller conveyor can be adjusted by adjusting the position of the first blocking ring 200, making the roller with the limiting structure more adaptable.

[0029] In some embodiments, the first limiting member 300 includes a first limiting pin 310, which is movable radially along the first blocking ring 200 and can stop at any position on its movement trajectory. By adjusting the position of the first limiting pin 310, the first limiting pin 310 can press against or disengage from the cylinder 100, thereby switching the first limiting member 300 between a first state and a second state. When the first limiting pin 310 presses against the cylinder 100, the friction between the first limiting pin 310 and the cylinder 100 can prevent the first blocking ring 200 from moving relative to the cylinder 100.

[0030] In some embodiments, the first blocking ring 200 has a first threaded hole 221, and the first limiting pin 310 has a first threaded end 311, which is screwed into the first threaded hole 221. Since the first threaded end 311 and the first threaded hole 221 are screwed together, the position of the first limiting pin 310 can be adjusted by rotating the first limiting pin 310, so that the first limiting pin 310 presses against or disengages from the cylinder 100, thereby allowing the first limiting member 300 to switch between a first state and a second state.

[0031] In some embodiments, the end of the first limiting pin 310 away from the first threaded end 311 has a first knob 312. An operator can rotate the first limiting pin 310 by rotating the first knob 312 to adjust the position of the first limiting pin 310.

[0032] In some embodiments, a first rubber pad 313 is provided at the head of the first threaded end 311. On the one hand, the first rubber pad 313 can increase the friction between the first limiting pin 310 and the cylinder 100, thereby more stably fixing the relative position between the first limiting pin 310 and the cylinder 100. On the other hand, the first rubber pad 313 is soft and can protect and prevent the end of the first limiting pin 310 from scratching the cylinder 100.

[0033] In some embodiments, there are multiple first limiting pins 310, and the multiple first limiting pins 310 are arranged circumferentially along the first blocking ring 200, thereby more stably fixing the relative position between the first limiting pins 310 and the cylinder 100.

[0034] In some embodiments, one end of the first blocking ring 200 has a convex first guide cone surface 210. The first guide cone surface 210 serves a guiding function. When the material approaches the first blocking ring 200, the material will first contact the first guide cone surface 210 and partially overlap the first guide cone surface 210. Under the guidance of the first guide cone surface 210, the material moves smoothly in the opposite direction and eventually detaches from the first guide cone surface 210.

[0035] In some embodiments, the end of the first blocking ring 200 away from the first guide cone surface 210 has a first mounting portion 220, and the first limiting member 300 is mounted on the first mounting portion 220. This prevents the first limiting member 300 mounted on the first mounting portion 220 from contacting the conveyed material.

[0036] In some embodiments, there are two first blocking rings 200, which are arranged opposite to each other. The two sets of oppositely arranged first blocking rings 200 together form a lateral movement range for the material.

[0037] In some embodiments, the roller with the limiting structure further includes a second blocking ring 400 and a second limiting member 500. The second blocking ring 400 is slidably disposed between two first blocking rings 200. The second limiting member 500 is mounted on the second blocking ring 400 and has a third state in which it is connected to the cylinder 100 to limit the sliding of the second blocking ring 400 relative to the cylinder 100, and a fourth state in which it is disengaged from the cylinder 100 to allow the second blocking ring 400 to slide relative to the cylinder 100.

[0038] In some embodiments, the second limiting member 500 includes a second limiting pin 510, which is movable radially along the second blocking ring 400 and can remain at any position on its movement trajectory. By adjusting the position of the second limiting pin 510, the second limiting pin 510 can press against or disengage from the cylinder 100, thereby switching the second limiting member 500 between a second state and a second state. When the second limiting pin 510 presses against the cylinder 100, the friction between the second limiting pin 510 and the cylinder 100 can prevent the second blocking ring 400 from moving relative to the cylinder 100.

[0039] In some embodiments, the second blocking ring 400 has a second threaded hole 421, and the second limiting pin 510 has a second threaded end 511, which is screwed into the second threaded hole 421. Since the second threaded end 511 and the second threaded hole 421 are screwed together, the position of the second limiting pin 510 can be adjusted by rotating it, so that the second limiting pin 510 presses against or disengages from the cylinder 100, thereby allowing the second limiting member 500 to switch between the second state and the second state.

[0040] In some embodiments, the end of the second limiting pin 510 away from the second threaded end 511 has a second knob 512. The operator can rotate the second limiting pin 510 by rotating the second knob 512 to adjust the position of the second limiting pin 510.

[0041] In some embodiments, a second rubber pad 513 is provided at the head of the second threaded end 511. On the one hand, the second rubber pad 513 can increase the friction between the second limiting pin 510 and the cylinder 100, thereby more stably fixing the relative position between the second limiting pin 510 and the cylinder 100. On the other hand, the second rubber pad 513 is soft and can protect and prevent the end of the second limiting pin 510 from scratching the cylinder 100.

[0042] In some embodiments, there are multiple second limiting pins 510, and the multiple second limiting pins 510 are arranged circumferentially along the second blocking ring 400, thereby more stably fixing the relative position between the second limiting pins 510 and the cylinder 100.

[0043] In some embodiments, one end of the second blocking ring 400 has an outwardly convex second guide cone surface 410. The second guide cone surface 410 serves a guiding function. When the material approaches the second blocking ring 400, the material will first contact the second guide cone surface 410 and partially overlap the second guide cone surface 410. Under the guidance of the second guide cone surface 410, the material moves smoothly in the opposite direction and eventually detaches from the second guide cone surface 410.

[0044] In some embodiments, the second blocking ring 400 has a second guide cone surface 410 formed at both ends, and a second mounting portion 420 in its middle, on which the second limiting member 500 is mounted. This prevents the second limiting member 500 mounted on the second mounting portion 420 from contacting the conveyed material.

[0045] In addition, this utility model provides a roller conveyor, which is equipped with several rollers with limit structures arranged side by side as described above.

[0046] To better understand this invention, the following is combined with... Figures 1 to 2 The technical solution of the present invention will be described in detail below:

[0047] First, the first blocking ring 200 is fitted onto the outer circumference of the cylinder 100. Since the first threaded end 311 and the first threaded hole 221 are screwed together, the position of the first limiting pin 310 can be adjusted by rotating it, causing the first limiting pin 310 to disengage from the cylinder 100. At this time, the position of the first blocking ring 200 can be adjusted. After the position of the first blocking ring 200 is adjusted, the first limiting pin 310 is rotated again, causing it to press against the cylinder 100, thereby fixing the relative position of the first blocking ring 200 and the cylinder 100. Because the relative position of the first blocking ring 200 and the cylinder 100 is adjustable, the movement trajectory of the workpiece on the roller conveyor can be adjusted by adjusting the position of the first blocking ring 200, making the roller with the limiting structure more versatile.
