[0002] p-Hydroxybenzoic acid is an organic compound with the molecular formula C7H6O3. The pure product is colorless fine crystals or crystalline powder. In addition to being effective against fungi, p-hydroxybenzoate esters have stronger antibacterial properties than benzoic acid and sorbic acid due to their phenolic hydroxyl structure. The characteristic of p-hydroxybenzoate esters is that their toxicity is lower than that of benzoic acid, and the antibacterial effect is independent of the pH value. When processing p-hydroxybenzoic acid, it is necessary to convey the materials to facilitate subsequent processing.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , the present invention provides a conveying device for the production of p-hydroxybenzoic acid, including a support frame 6 and a conveying mechanism connected to the top of the support frame 6. The conveying mechanism includes a first motor 4 and a conveyor belt 2, and the first motor 4 is used to drive the conveyor belt 2 to rotate. A tensioning mechanism is connected to the side of the support frame 6. The tensioning mechanism includes a cylinder 9, a moving seat 12, a second spring 19, a pull rod 13, a rotating block 14, and a feeding plate 3. The cylinder 9 is used to drive the moving seat 12 to reciprocate. One end of the pull rod 13 is inserted into the moving seat 12, and the other end is connected to the rotating block 14. Both ends of the second spring 19 are connected to the moving seat 12 and the pull rod 13. The feeding plate 3 is connected to the moving seat 12. A pressing mechanism for pressing against the material barrel is connected to the bottom of the side of the support frame 6.

[0022] Support wheels are connected to the bottom of the support frame 6. The conveying device is moved to the side of the processing device. Then, the cylinder 9 drives the moving seat 12 to move backward, synchronously driving the pull rod 13, the rotating block 14, and the feeding plate 3 to move backward, so that the rotating block 14 presses against the inner wall of the material barrel. At this time, the second spring 19 is in a stretched state, and the top of the feeding plate 3 abuts against the conveyor belt 2. At the same time, the pressing plate 10 presses against the outer wall of the material barrel, thereby improving the stability of the connection between the conveying frame 1 and the material barrel. The feeding plate 3 can not only scrape the materials attached to the conveyor belt 2, improve the cleanliness of the conveyor belt 2, but also smoothly convey the materials into the material barrel, avoiding the materials from falling to the ground and causing waste of resources.

[0023] The conveying mechanism further includes a conveying frame 1 and two rotating rollers 17. The two ends of the rotating roller 17 are rotatably connected inside the conveying frame 1. The conveying frame 1 is connected to the top of the support frame 6. The two rotating rollers 17 are drivingly connected by a conveyor belt 2. The power output end of the first motor 4 is connected to the rotating roller 17. The first motor 4 can drive the rotating roller 17 to rotate, and then cooperate with the use of the conveyor belt 2 to realize the operation of the conveyor belt 2, facilitating the transfer and transportation of materials.

[0024] The tensioning mechanism further includes two guide plates 11, a guide block 20, and a connecting plate 18. The guide plate 11 is used to guide the moving seat 12. The guide block 20 is slidably connected inside the moving seat 12, and the guide block 20 is connected to the end of the pull rod 13. The second spring 19 is located inside the moving seat 12, and the two ends of the second spring 19 are connected to the guide block 20 and the moving seat 12. The two ends of the connecting plate 18 are fixedly connected to the moving seat 12 and the feeding plate 3. When the rotating block 14 presses against the inner wall of the cylinder, the cylinder 9 can continue to drive the moving seat 12 to move backward, synchronously driving the feeding plate 3 to continue to move backward, so that the pressure exerted by the top of the feeding plate 3 on the conveyor belt 2 is further increased, and the materials with strong adhesion on the surface of the conveyor belt 2 can be scraped off. The position of the feeding plate 3 is adjusted according to the viscosity of the materials, with strong applicability. At the same time, the second spring 19 is further stretched, increasing the pulling force exerted by the rotating block 14 on the cylinder, and further strengthening the stability of the connection between the conveying frame 1 and the cylinder.

[0025] The support frame 6 is connected to an upper cross plate 5. One end of the guide plate 11 is connected to the moving seat 12, and the other end passes through the upper cross plate 5. The guide plate 11 makes the reciprocating movement of the moving seat 12 stable, playing a good guiding role.

[0026] The cylinder 9 is fixed to the upper cross plate 5, and the power output end of the cylinder 9 is connected to the moving seat 12. The moving seat 12 is slidably connected to the upper cross plate 5, making the movement of the moving seat 12 stable.

[0027] The rotating block 14 is rotatably connected to the pull rod 13 through a damping shaft, enabling the rotating block 14 to rotate at multiple angles and having a certain sense of damping. When the conveying frame 1 and the cylinder are just docked, the rotating block 14 is in a horizontal position, making the rotating block 14 located above the cylinder. Then, the rotating block 14 is rotated to a vertical state, facilitating the connection with the cylinder.

[0028] The abutting mechanism includes a connecting seat 8, an abutting plate 10, a guide groove 16, and a plurality of first springs 15. The connecting seat 8 is fixedly connected to the lower cross plate 7 of the support frame 6. The guide groove 16 is arranged inside the connecting seat 8. The abutting plate 10 is slidably connected to the guide groove 16. The two ends of the first spring 15 are connected to the connecting seat 8 and the abutting plate 10. When the rotating block 14 presses against the inner wall of the cylinder, the bottom end of the side of the cylinder is connected to the abutting plate 10, and the first spring 15 is compressed. That is, the abutting mechanism and the tensioning mechanism are used in cooperation to make the connection between the conveying frame 1 and the cylinder stable.

[0029] The side surface of the bottom plate 10 is an arc structure, and the arc structure matches the outer side surface of the barrel.

[0030] Working principle: Move the conveying device to one side of the processing device, and then rotate the rotating block 14 to make it in a vertical state. The cylinder 9 drives the moving seat 12 to move backward, synchronously driving the feeding plate 3, the pull rod 13, and the rotating block 14 to move backward, so that the rotating block 14 presses against the inner wall of the barrel, and the second spring 19 is in a stretched state. The top of the feeding plate 3 abuts against the conveyor belt 2. At the same time, the barrel is connected to the bottom plate 10, which can improve the stability of the connection between the conveying frame 1 and the barrel and facilitate the conveying of materials. The feeding plate 3 can scrape the materials attached to the surface of the conveyor belt 2, improve the cleanliness of the conveyor belt 2, and eliminate the need for manual cleaning. The materials are conveyed into the barrel through the feeding plate 3 for processing, avoiding the waste of resources caused by the materials falling to the ground, and having strong practicability.
