Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a U-shaped turning conveyor. Background Technology

[0002] For industries requiring space optimization, complex path conveying, or high reliability, U-shaped turn conveyors effectively save space and ensure smooth and safe material transport during turns. U-shaped turn conveyors use perforated mesh belts, facilitating the transition from straight to curved paths.

[0003] However, foreign objects may fall into the turning conveyor belt during operation. If it enters the turning bend directly, the foreign objects in the mesh may be squeezed and damage the turning conveyor belt. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution;

[0007] U-shaped turning conveyor special turning mesh belt, including the conveyor mesh belt installed in the conveyor;

[0008] The conveyor is equipped with a U-shaped bend, which includes a bend, an entry straight section into the bend, and an exit straight section out of the bend.

[0009] The conveyor also includes a collection box disposed on the U-shaped mesh belt. The collection box is disposed on the straight section, and the opening of the collection box faces the opposite direction to the direction in which the conveyor belt enters the curve. The lower side of the collection box is attached to the upper side of the conveyor belt.

[0010] The collection box is connected to a rotating mechanism, which is located beside the entrance straight path;

[0011] A jet nozzle is also provided below the turning mesh belt, with the nozzle facing upward toward the turning mesh belt, and the jet nozzle is connected to a high-pressure air pipeline;

[0012] At least three jet heads are arranged along the width of the turning mesh belt, with the nozzles of the at least three jet heads facing the opening of the collection box and pointing forward.

[0013] The aforementioned design includes a collection box located on the straight section of the conveyor belt to collect foreign objects (scattered materials or debris) that have fallen from the belt. This prevents foreign objects from getting stuck in the mesh and being crushed when the belt deforms at bends, reducing conveyor belt jamming or deformation caused by debris. The collection box is connected to a rotating mechanism, which rotates to allow transported materials to pass through, ensuring smooth conveyor operation. Air jets are also installed below the turning conveyor belt. These jets use high-pressure airflow to blow out any stuck foreign objects. At least three jets are positioned in front of the collection box opening to collect the blown-out foreign objects, preventing them from falling back into the conveyor belt mesh. This effectively removes foreign objects from the conveyor belt mesh, reducing conveyor belt jamming or deformation caused by debris.

[0014] The distance between the collection box and the bend is not less than the length of the collection box.

[0015] Preferably, the conveyor is provided with a fixed support frame, the rotating mechanism includes a rotating shaft fixed on the support frame, the rotating shaft is provided on the side of the entry straight track, a stop is provided on the other side of the entry straight track, and the collection box is provided between the rotating shaft and the stop.

[0016] A rotating sleeve is fitted onto the rotating shaft, and the rotating sleeve is connected to the collection box;

[0017] A torsion spring for resetting the collection box is provided between the rotating shaft and the rotating sleeve.

[0018] The collection box can rotate along the pivot, allowing it to be easily pushed open by materials transported on the conveyor belt, preventing it from interfering with the belt's operation. The torsion spring can reset the collection box against the stop block, allowing it to be repositioned on the conveyor belt to collect foreign objects. This facilitates the automatic operation of the collection box on the conveyor belt.

[0019] Preferably, the bottom side of the collection box is provided with an electric door, and the opening direction of the electric door is opposite to the direction in which the opening faces.

[0020] The electric door is connected to a trigger switch, which is located on the same side as the rotating shaft. A trigger block is provided on the collection box, and at least a portion of the trigger block protrudes from the opening of the collection box to the side facing away from it. The distance between the trigger block and the rotating shaft is equal to the distance between the trigger switch and the rotating shaft, and their heights are equal.

[0021] The electric door can be opened by triggering the switch and trigger block, which can automatically discharge foreign objects from the collection box without manual operation and maintenance, saving manpower.

[0022] Preferably, a PTFE (polytetrafluoroethylene) shovel block is also provided on the lower side of the opening, and the height of the shovel block gradually decreases from the inside to the outside of the opening. The PTFE shovel block is more wear-resistant and causes less wear on the conveyor belt, making it suitable for long-term use.

[0023] Preferably, the upper side of the electric gate is lower than the upper end of the shovel block, and the shovel block and the upper side of the electric gate form a step with a height difference.

[0024] The varying heights of the steps create a space for storing foreign objects, preventing them from rolling out of the opening when the collection box moves.

[0025] Preferably, a push block made of sponge material is also provided above the collection box. The push block is higher than the upper end of the opening and extends out from the opening in the direction of the opening.

[0026] By incorporating a pusher made of rigid sponge, the collection box and the materials being transported by the conveyor belt are prevented from scratching each other.

[0027] Preferably, the pusher is positioned in the middle of the collection box;

[0028] The length of the pusher block is not less than one-third of the length of the collection box;

[0029] The pusher extends at least 10 cm from the opening in the direction it faces.

[0030] Ensure the collection box is protected by the push block.

[0031] Preferably, the collection box is provided with a mounting block, and the mounting block is provided with at least two through holes;

[0032] At least two through holes are slidably fitted with guide posts, all of which are connected to the push block. Each guide post is also fitted with a spring, one end of which is connected to the push block and the other end of which is connected to the mounting block.

[0033] The extension and retraction stroke of the mounting block is increased by using guide posts and springs, which improves the buffering capacity of the mounting block, protects the material and the collection box, and prevents the mounting block from getting stuck on the running material after the collection box is pushed open.

[0041] Example 1

[0042] refer to Figures 1-2 A special turning mesh belt for U-shaped turning conveyors, including a conveyor mesh belt 1 installed in the conveyor.

[0043] The conveyor is equipped with a U-shaped bend, which includes a bend, an entry straight section into the bend, and an exit straight section out of the bend.

[0044] The conveyor also includes a collection box 2 disposed on the U-shaped mesh belt. The collection box 2 is disposed on the straight section, and the opening 21 of the collection box 2 faces the opposite direction to the direction in which the conveyor belt 1 enters the curve. The lower side of the collection box 2 is attached to the upper side of the conveyor belt 1.

[0045] The collection box 2 is connected to the rotating mechanism, which is located on the side of the straight path leading in;

[0046] Below the turning mesh belt, there is also a jet head 8, with the nozzle of the jet head 8 facing upward toward the turning mesh belt, and the jet head 8 is connected to a high-pressure air pipeline;

[0047] At least three jet heads 8 are arranged along the width of the turning mesh belt, and the nozzles of the at least three jet heads 8 face the front of the opening 21.

[0048] The above design includes a collection box 2 positioned on the straight section to collect foreign objects (scattered materials or debris) falling from the conveyor belt 1. This prevents foreign objects from getting stuck in the mesh of the conveyor belt 1 and being crushed when it deforms at bends, reducing the risk of the conveyor belt 1 getting stuck or deformed due to debris. The collection box 2 is connected to a rotating mechanism, which can rotate to allow the material to pass through, ensuring the smooth operation of the conveyor. Air jets 8 are also installed below the turning conveyor belt. These jets use high-pressure airflow to blow out any stuck foreign objects. At least three jets 8 are positioned in front of the opening 21 of the collection box 2 to collect the foreign objects blown out by the jets, preventing them from falling back into the mesh of the conveyor belt 1. This effectively removes foreign objects from the mesh of the conveyor belt 1, reducing the risk of the conveyor belt 1 getting stuck or deformed due to debris.

[0049] The conveyor is equipped with a fixed support frame 3. The rotating mechanism includes a rotating shaft 4 fixed on the support frame 3. The rotating shaft 4 is located on one side of the entry straight track, and a stop is located on the other side of the entry straight track. The collection box 2 is located between the rotating shaft 4 and the stop. A rotating sleeve 5 is fitted onto the rotating shaft 4 and connected to the collection box 2. A torsion spring for resetting the collection box 2 is provided between the rotating shaft 4 and the rotating sleeve 5. This allows the collection box 2 to rotate along the rotating shaft 4, facilitating its movement by being pushed open by materials transported on the conveyor belt 1, preventing the collection box 2 from affecting the operation of the conveyor belt 1. The torsion spring can reset the collection box 2 against the stop, allowing it to be re-erected on the conveyor belt 1 to collect foreign objects. This facilitates the automatic operation of the collection box 2 on the conveyor belt 1.

[0050] An electric door is provided on the bottom side of the collection box 2, and the opening direction of the electric door is opposite to the orientation of the opening 21. The electric door is connected to a trigger switch 31, which is located on the same side as the rotating shaft 4. A trigger block 24 is provided on the collection box 2, and at least a portion of the trigger block 24 protrudes from the side opposite to the opening 21 of the collection box 2. The distance between the trigger block 24 and the rotating shaft 4 is equal to the distance between the trigger switch 31 and the rotating shaft 4, and they are at the same height. By triggering the electric door with the trigger switch 31 and the trigger block 24, foreign objects in the collection box 2 can be automatically discharged, eliminating the need for manual operation and maintenance, thus saving manpower.

[0051] In use, the collection box 2, located on the straight section, collects foreign objects falling from the conveyor belt 1. The collection box 2 is connected to a rotating mechanism, allowing it to rotate along the shaft 4. This facilitates the collection box 2 being pushed open by the material transported on the conveyor belt 1, ensuring smooth operation of the conveyor. Air jets 8 are also installed below the curved conveyor belt. These jets use high-pressure airflow to blow out any stuck foreign objects. At least three jets 8 are positioned in front of the opening 21 of the collection box 2 to collect the foreign objects blown out by the jets, preventing them from falling back into the mesh of the conveyor belt 1. This process removes foreign objects from the mesh of the conveyor belt 1, reducing the risk of jamming or deformation caused by debris. It also prevents foreign objects stuck in the mesh of the conveyor belt 1 from being crushed during curves, further reducing the risk of jamming or deformation caused by debris. When the collection box 2 is opened, the trigger switch 31 and trigger block 24 activate the electric door, automatically discharging the foreign objects from the collection box 2 without requiring manual operation or maintenance, saving manpower.

[0052] Example 2

[0053] refer to Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0054] A PTFE (polytetrafluoroethylene) shovel block 22 is also provided on the lower side of the opening 21. The height of the shovel block 22 gradually decreases from the inside to the outside of the opening 21. The PTFE shovel block 22 is more wear-resistant and causes less wear to the conveyor belt 1, making it suitable for long-term use.

[0055] The upper side of the electric gate is lower than the upper end of the shovel block 22, forming a height difference step between the shovel block 22 and the upper side of the electric gate. This height difference step creates a space for collecting foreign objects, preventing them from rolling out of the opening 21 when the collection box 2 moves.

[0056] A sponge-material pusher block 6 is also provided above the collection box 2. The pusher block 6 is higher than the upper end of the opening 21 and extends out from the opening 21 in the direction of the opening. The pusher block 6 is made of rigid sponge to prevent the collection box 2 from scratching the materials transported by the conveyor belt 1.

[0057] The push block 6 is positioned in the middle of the collection box 2; the length of the push block 6 is not less than one-third of the length of the collection box 2; the push block 6 extends at least 10cm from the opening 21 in the direction of the opening. This ensures that the collection box 2 is protected by the push block 6.

[0058] The collection box 2 is provided with a mounting block 23, which has at least two through holes. Guide posts 7 are slidably fitted into each of the at least two through holes, and all guide posts 7 are connected to the push block 6. A spring is also fitted onto each guide post 7, with one end connected to the push block 6 and the other end connected to the mounting block 23. The guide posts 7 and springs increase the extension and retraction stroke of the mounting block 23, improving its buffering capacity, protecting the material and the collection box 2, and preventing the mounting block 23 from jamming the moving material after the collection box 2 is pushed open.

[0059] When in use, the PTFE (polytetrafluoroethylene) shovel block 22 of the collection box 2 is more wear-resistant and causes less wear to the conveyor belt 1, making it suitable for long-term use. The varying height of the steps creates a space to collect foreign objects, preventing them from rolling out of the opening 21 when the collection box 2 moves. The material-pushing rigid sponge block 6 pushes the collection box 2 open, preventing the collection box 2 from scratching the material transported by the conveyor belt 1. The guide post 7 and spring increase the extension stroke of the mounting block 23, preventing the mounting block 23 from getting stuck on the moving material after the collection box 2 is pushed open.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
