Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt testing technology, and in particular relates to a testing device for anti-slip conveyor belts. Background Technology

[0002] A conveyor belt (also known as a transport belt) is a flexible composite product used for continuous or intermittent material transport. It is usually made of materials such as rubber, fiber, metal or plastic and is the core component of a belt conveyor.

[0003] In traditional belt conveyors, the conveyed items can cause the belt to slip, and prolonged use and wear can also lead to slippage. When the belt slips, it not only affects the conveying of items, but the rollers will also continuously rub against the belt, causing severe wear on one part of the belt, reducing its service life, and slippage will still frequently occur in subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for anti-slip conveyor belts. Specifically, when the conveyor belt slows down or stops, an electric push rod pushes a push block to the left, which in turn pushes an inclined block. This inclined block then causes the lifting seat to move upwards, and the push roller moves along with it, pushing the conveyor belt upwards. This increases the tension of the conveyor belt, ensuring smooth transmission and preventing slippage. This method prevents continuous friction between the conveyor belt and the rotating roller, reducing belt wear and extending its service life. It solves the problem that slippage during belt conveying not only affects the transport of goods but also causes continuous friction between the rotating roller and the belt, resulting in severe wear and reduced belt life.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a detection device for anti-slip conveyor belts, including a belt conveyor, a controller fixedly connected to the front of the belt conveyor, and further comprising:

[0007] A tension adjusting unit, mounted on top of the belt conveyor, is used to adjust the tension of the conveyor belt; and

[0008] A protective section is installed on top of the belt conveyor and is used to shield the edges of the conveyor belt.

[0009] The controller is used to control the start of the belt conveyor, and the belt conveyor has an opening at its bottom.

[0010] Furthermore, the tension adjustment unit includes a support frame fixedly connected to the bottom opening of the belt conveyor, an electric push rod fixedly connected to the inner side of the support frame, and a push block fixedly connected to the output end of the electric push rod; the electric push rod is connected to the controller through a wiring harness, and the support frame is installed on the belt conveyor by welding.

[0011] A lifting assembly is installed inside the bottom opening of the belt conveyor and is used to push the belt on the belt conveyor.

[0012] The belt conveyor is fixedly connected to two limiting plates at its bottom. The two limiting plates are located on the front and back of the lifting assembly, and the limiting plates have grooves inside.

[0013] Furthermore, the protective component includes a fixed frame fixedly connected to the top of the belt conveyor, on which a non-contact speed detector is mounted; and

[0014] A shielding assembly, which is mounted on top of the belt conveyor;

[0015] The mounting bracket is used to support and fix the non-contact speed detector, which is used to monitor the transmission speed of the conveyor belt on the belt conveyor. The non-contact speed detector is connected to the controller via a wiring harness.

[0016] Furthermore, the lifting assembly includes two vertical plates disposed inside the limiting plate. A lifting seat is fixedly connected to the top of the vertical plates. Two push rollers are rotatably connected to the top of the lifting seat. Slider blocks are fixedly connected to the two vertical plates on opposite sides. An inclined block is fixedly connected to the bottom of the lifting seat. The limiting plate is installed at the bottom of the belt conveyor by welding. The vertical plates and the lifting seat are connected by welding. The inclined block and the lifting seat are integrally formed.

[0017] The bottom of the inclined block is set with an inclined surface, the push block is in contact with the inclined surface above, and the push roller is in contact with the bottom of the conveyor belt.

[0018] Furthermore, the slider is slidably connected in the groove of the limiting plate, and the slider and the limiting plate cooperate to limit the lifting seat when it is raised or lowered.

[0019] Furthermore, the shielding assembly includes two shielding ramps, and several connecting frames are fixedly connected to the sides of the two shielding ramps that are far apart from each other. Several insert blocks are fixedly connected to the top of the belt conveyor. The insert blocks have cavities inside. The shielding ramps are inclined.

The insert blocks are installed on the belt conveyor by welding, and the connecting frames are installed on the ramps by welding.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, by setting up a tension adjustment part, specifically, when the conveyor belt slows down or stops, the electric push rod will push the push block to the left, the push block will push the inclined block, at this time the inclined block will drive the lifting seat to move upward, and the push roller will move together, and the push roller will push the conveyor belt upward, thereby increasing the tension of the conveyor belt, so that the conveyor belt can be smoothly transmitted, thereby avoiding slippage.

[0032] 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 scope of protection of the present utility model.

[0033] Please see Figures 1-5 As shown, this utility model is a detection device for an anti-slip conveyor belt, including a belt conveyor 1, a controller 11 fixedly connected to the front of the belt conveyor 1, and further including:

[0034] Tension adjusting unit 2, installed on top of belt conveyor 1, is used to adjust the tension of the conveyor belt; and

[0035] Protective part 3 is installed on top of belt conveyor 1 and is used to cover the edge of the conveyor belt.

[0036] The controller 11 is used to control the start of the belt conveyor 1, and the belt conveyor 1 has an opening at the bottom.

[0037] The tension adjustment unit 2 includes a support frame 21 fixedly connected to the bottom opening of the belt conveyor 1, an electric push rod 211 fixedly connected to the inner side of the support frame 21, and a push block 212 fixedly connected to the output end of the electric push rod 211.

[0038] Lifting assembly 22 is installed in the bottom opening of belt conveyor 1 and is used to push the belt on belt conveyor 1.

[0039] Among them, the bottom of the belt conveyor 1 is fixedly connected to two limiting plates 23. The two limiting plates 23 are set on the front and back of the lifting component 22, and the limiting plates 23 are provided with sliding grooves inside.

[0040] The protective unit 3 includes a fixed frame 31 fixedly connected to the top of the belt conveyor 1, on which a non-contact speed detector 32 is mounted; and

[0041] A shielding assembly 33 is installed on top of the belt conveyor 1;

[0042] The fixing frame 31 is used to support and fix the non-contact speed detector 32, which is used to monitor the transmission speed of the conveyor belt on the belt conveyor 1.

[0043] The lifting assembly 22 includes two vertical plates 221 disposed inside the limiting plate 23. A lifting seat 222 is fixedly connected to the top of the vertical plates 221. Two push rollers 223 are rotatably connected to the top of the lifting seat 222. A slider 224 is fixedly connected to the side of the two vertical plates 221 that is far apart from each other. An inclined block 225 is fixedly connected to the bottom of the lifting seat 222. When the conveyor belt slows down or stops, the electric push rod 211 pushes the push block 212 to the left. The push block 212 pushes the inclined block 225. At this time, the inclined block 225 drives the lifting seat 222 to move upward, and the push rollers 223 move together. The push rollers 223 push the conveyor belt upward, thereby increasing the tension of the conveyor belt and making the conveyor belt smoothly transmitted, thus avoiding slippage. This method can prevent the conveyor belt from continuously rubbing against the rotating rollers, reduce the wear of the conveyor belt and improve its service life.

[0044] Among them, the bottom of the inclined block 225 is set with an inclined surface, the push block 212 contacts the inclined surface on 215, and the push roller 223 contacts the bottom of the conveyor belt.

[0045] The slider 224 is slidably connected in the groove on the limiting plate 23. The slider 224 and the limiting plate 23 cooperate to limit the lifting seat 222 when it is raised or lowered.

[0046] The shielding assembly 33 includes two shielding ramps 331. Several connecting frames 332 are fixedly connected to the side of the two shielding ramps 331 that are far apart from each other. Several insert blocks 333 are fixedly connected to the top of the belt conveyor 1. The insert blocks 333 have cavities inside. The shielding ramps 331 are inclined. There is space between the bottom of the shielding ramps 331 and the conveyor belt. The bottom of the connecting frames 332 is inserted into the insert blocks 333. The shielding ramps 331 will shield the material conveyed by the conveyor belt on the belt conveyor 1, so that the material will not move to the edge of the conveyor belt. This not only protects the non-contact speed detector 32, but also reduces the impact of the material on the non-contact speed detector 32's measurement of the conveyor belt speed.

[0047] One specific application of this embodiment is:

[0048] During use, the non-contact speed detector 32 monitors the speed of the conveyor belt on the belt conveyor 1 during the conveying process. The non-contact speed detector 32 is model DH-F1. The blocking plate 331 is inserted into the insert block 333 through the connecting frame 332 to install the blocking plate 331. At this time, the blocking plate 331 will block the material conveyed by the conveyor belt on the belt conveyor 1, so that the material will not move to the edge of the conveyor belt. This not only protects the non-contact speed detector 32, but also reduces the impact of the material on the non-contact speed detector 32's measurement of the conveyor belt speed. The blocking plate 331 can be removed by pulling it upward, which facilitates the subsequent maintenance of the non-contact speed detector 32.

[0049] When the non-contact speed detector 32 detects that the conveyor belt is moving too slowly or is not moving, it sends an electrical signal to the controller 11. The controller 11 then activates the electric push rod 211, which pushes the push block 212 to the left. Because the bottom of the inclined block 225 is sloped, the push block 212 pushes the inclined block 225. This causes the inclined block 225 to move the lifting seat 222 upwards, and the push roller 223 moves along with it. The push roller 223 then pushes the conveyor belt upwards, thereby increasing the tension of the conveyor belt. The conveyor belt is smoothly driven, thus avoiding slippage. At the same time, during the movement of the lifting seat 222, the vertical plate 221 will drive the slider 224 to move together. The slider 224 will slide in the groove on the limiting plate 23 to limit the lifting seat 222 and make it move in a straight line. When the non-contact speed detector 32 detects that the speed of the conveyor belt is normal, the controller 11 controls the electric push rod 211 to retract and reset the push block 212. The lifting seat 222 will then reset downward by gravity. At this time, the push roller 223 will not push the conveyor belt.
