Description

Technical Field

[0001] This utility model relates to the technical field of anti-tear devices, and in particular to a high-precision pallet-feeding longitudinal anti-tear device. Background Technology

[0002] During the material conveying process, belt conveyors inevitably encounter various factors that can lead to problems such as perforation, tearing, and breakage, severely impacting production. Given the high value of belts, early detection of damage and material leakage, along with timely shutdown, can prevent further damage and mitigate the escalation of accidents and their consequences.

[0003] Traditional tear-resistant devices use a pull-cord type, but they may not activate in some situations and cannot respond to all types of tearing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-precision pallet unloading longitudinal anti-tear device with a variable torque design that does not automatically reset once the action is triggered, and features high precision, high reliability, and vibration resistance.

[0005] This utility model relates to a high-precision pallet-type longitudinal tear-resistant device, comprising a frame and shaft seats, with both sets of shaft seats mounted on the outer wall of the frame. It also includes a limiting device, a detection device, a screen plate, a baffle, a contact rod, and a contact sensor. The screen plate is mounted at an inclined angle and rotatably on the two sets of shaft seats. The baffle is located on the outer wall of the lower end of the screen plate. The contact rod is mounted on the outer wall of the lower end of the screen plate. The contact sensor is mounted on the outer wall of the frame, with the contact sensor corresponding to the position of the contact rod. The limiting device is located on the outer wall of the higher end of the screen plate, used to support and limit the movement of that higher end. The detection device is located on the frame and is used to detect broken or punctured foreign objects on the belt. The frame is installed below the belt, with the lower end of the screen plate facing the conveying direction of the belt. When the belt is running, dust... Some material can fall through the screen of the screen plate. If large pieces of material leak out, particles larger than 4mm in diameter will accumulate on the screen plate on one side of the baffle. Once the weight exceeds the set limit, the screen plate will rotate around the shaft seat and drive the touch rod downward. After the touch rod moves downward, it will press the detection end of the contact sensor, thereby triggering the contact sensor to change its output state and triggering the belt to stop. When the belt breaks, the belt part will scatter and droop, triggering the detection device. The detection device will press the detection end of the contact sensor, thereby triggering the belt to stop. When the fault is resolved and the material on the screen plate needs to be removed, the detection device will reset, flip the screen plate backward, and move the touch rod upward to reset. The device will then resume the monitoring mode. The device adopts a variable torque design concept. Once the action is triggered, it will not automatically reset. It has the characteristics of high precision, high reliability, and vibration resistance.

[0006] Preferably, the detection device includes a support arm, a rotating arm, and a crossbar swing arm. The bottom end of the support arm is connected to the outer wall of the frame, the rotating arm is rotatably mounted on the top end of the support arm, and the crossbar swing arm is located on the top end of the rotating arm. In the initial state, the support arm and the rotating arm are at a vertical angle. When the belt breaks, the weight of the belt presses down on the crossbar swing arm, causing the rotating arm to flip forward. This causes the rotating arm to press down on the detection end of the contact sensor, thereby triggering the belt to stop. At the same time, when there is a punctured foreign object on the belt, the foreign object will push the crossbar swing arm forward during the belt conveying process, causing the rotating arm to flip forward and triggering the belt to stop, thereby reducing losses.

[0007] Preferably, the limiting device includes a limiting frame and a hinge, which are rotatably mounted on the outer wall of the higher end of the screen plate. In the initial state, the bottom end of the limiting frame contacts the outer wall of the frame to support the higher end of the screen plate. When the screen plate flips forward, the screen plate drives the limiting frame to move upward and separate from the frame, thereby facilitating the limiting frame to support and limit the higher end of the screen plate and ensuring the tilt angle of the screen plate.

[0008] Preferably, the device also includes a bracket and bolts. The bracket is installed on the outer wall of the frame, and multiple sets of bolts are installed on the bracket. By setting the bracket and multiple sets of bolts, it is convenient to install the device under belt conveyors of different sizes, thereby improving ease of use.

[0009] Preferably, it also includes an electrical junction box and indicator lights. The electrical junction box is installed on the outer wall of the frame, and the indicator lights are connected to the circuit inside the electrical junction box. By setting up the electrical junction box, the protection and safety of the circuit is improved, and by setting up the indicator lights, the convenience of observing the circuit's operating status is improved.

[0010] Preferably, it also includes a material drop sensor, which is installed on the outer wall of the frame; by setting the material drop sensor, the convenience of detecting the material falling onto the screen plate is improved.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The frame is installed below the belt, and the lower end of the screen plate faces the conveying direction of the belt. When the belt is running, some dust can fall from the screen of the screen plate. If large pieces of material leak out, particles with a diameter greater than 4mm will accumulate on the screen plate on one side of the baffle. After exceeding the set weight, the screen plate rotates around the shaft seat and drives the touch rod to move downward. After the touch rod moves downward, it presses the detection end of the contact sensor, thereby triggering the contact sensor to change the output state and triggering the belt to stop. When the belt breaks, the belt part falls and triggers the detection device. The detection device presses the detection end of the contact sensor, thereby triggering the belt to stop. When the fault is dealt with and the material on the screen plate needs to be removed, the detection device resets, flips the screen plate backward, and moves the touch rod upward to reset. The device resumes the monitoring working mode again. The device adopts a variable torque design concept. Once the action is triggered, it will not automatically reset. It has the characteristics of high precision, high reliability, and vibration resistance. Attached Figure Description

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] Example 1

[0019] like Figures 1 to 4As shown, the high-precision pallet-feeding longitudinal anti-tear device of this utility model includes a frame 1 and a bearing 2, both bearings 2 are mounted on the outer side wall of the frame 1; it also includes a limiting device, a detection device, a screen plate 3, a baffle 4, a contact rod 5 and a contact sensor 6. The screen plate 3 is tilted and rotatably mounted on the two bearings 2. The baffle 4 is set on the outer side wall of the lower end of the screen plate 3. The contact rod 5 is installed on the outer side wall of the lower end of the screen plate 3. The contact sensor 6 is installed on the outer side wall of the frame 1, and the position of the contact sensor 6 corresponds to that of the contact rod 5. The limiting device is set on the outer side wall of the higher end of the screen plate 3. The limiting device is used to support and limit the higher end of the screen plate 3. The detection device is set on the frame 1. The detection device is used to detect broken or punctured foreign objects on the belt.

[0020] like Figure 1 As shown, the detection device includes a support arm 7, a rotating arm 8, and a horizontal bar swing arm 9. The bottom end of the support arm 7 is connected to the outer wall of the frame 1, the rotating arm 8 is rotatably mounted on the top end of the support arm 7, and the horizontal bar swing arm 9 is located on the top end of the rotating arm 8.

[0021] In this embodiment, the frame 1 is installed below the belt, with the lower end of the screen plate 3 facing the conveying direction of the belt. When the belt is running, dust can fall from the screen of the screen plate 3. If large pieces of material leak out, particles with a diameter greater than 4mm will accumulate on the screen plate 3 on one side of the baffle 4. Once the weight exceeds the set limit, the screen plate 3 will rotate around the shaft seat 2 and drive the touch rod 5 to move downward. After the touch rod 5 moves downward, it will press the detection end of the contact sensor 6, thereby triggering the contact sensor 6 to change its output state and triggering the belt to stop. When the belt breaks, the belt part will scatter and droop, triggering the detection device. The detection device will press the detection end of the contact sensor 6, thereby triggering the belt to stop. When the fault is resolved and the material on the screen plate 3 needs to be removed, the detection device will reset, flip the screen plate 3 backward, and move the touch rod 5 upward to reset. The device will then resume the monitoring mode. The device adopts a variable torque design concept. Once the action is triggered, it will not automatically reset, and it has the characteristics of high precision, high reliability, and vibration resistance.

[0022] Example 2

[0023] Based on Example 1, such as Figure 2 As shown, the high-precision pallet-type longitudinal anti-tear device of this utility model includes a limiting frame 10 and a hinge 11, which are rotatably mounted on the outer wall of the higher end of the screen plate 3.

[0024] like Figure 2 As shown, it also includes a bracket 12 and bolts 13. The bracket 12 is installed on the outer wall of the frame 1, and multiple sets of bolts 13 are all set on the bracket 12.

[0025] like Figure 2 As shown, it also includes an electrical junction box 14 and an indicator light 15. The electrical junction box 14 is installed on the outer wall of the frame 1, and the indicator light 15 is connected to the circuit inside the electrical junction box 14.

[0026] like Figure 3 As shown, it also includes a material drop sensor 16, which is mounted on the outer wall of the frame 1;

[0027] In this embodiment, the support arm 7 and the rotating arm 8 are initially at a vertical angle. When the belt breaks, the weight of the belt presses down on the crossbar arm 9, causing the rotating arm 8 to flip forward. This causes the rotating arm 8 to press down on the detection end of the contact sensor 6, thereby triggering the belt to stop. At the same time, when there is a punctured foreign object on the belt, the foreign object will push the crossbar arm 9 forward during the belt conveying process, causing the rotating arm 8 to flip forward and triggering the belt to stop, thereby reducing losses. In the initial state, the bottom end of the limiting frame 10 contacts the outer wall of the frame 1 to support the higher end of the screen plate 3. When the screen plate 3 flips forward, the screen plate 3 drives the limiting frame 10 to move upward and separate from the frame 1, thereby facilitating the limiting frame 10 to support and limit the higher end of the screen plate 3, and facilitating the maintenance of the tilt angle of the screen plate 3.

[0028] This utility model relates to a high-precision pallet-type longitudinal anti-tear device. During operation, the frame 1 is installed below the belt, with the lower end of the screen plate 3 facing the conveying direction of the belt. As the belt runs, dust can fall through the screen of the screen plate 3. If large pieces of material leak out, particles larger than 4mm in diameter accumulate on the screen plate 3 on one side of the baffle 4. Once the weight exceeds the set limit, the screen plate 3 rotates around the shaft seat 2, causing the contact rod 5 to move downwards. The downward movement of the contact rod 5 presses the detection end of the contact sensor 6, triggering the sensor 6 to change its output state and stop the belt. When the belt breaks, the sag of the belt triggers the detection device, which presses the detection end of the contact sensor 6, thus stopping the belt. When the fault is resolved and the material on the screen plate 3 needs to be removed, the detection device resets, flipping the screen plate 3 backwards to move the contact rod 5 upwards.

[0029] The contact sensor 6, electrical junction box 14, indicator light 15, and dropping sensor 16 of this high-precision pallet dropping longitudinal anti-tear device are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
