Description

Technical Field

[0001] This application relates to the field of adhesive powder processing, and in particular to a conveying device for adhesive powder pretreatment. Background Technology

[0002] With the increasing amount of scrapped tires, the number of waste tires is rapidly growing and piling up everywhere, not only occupying a lot of space but also seriously deteriorating the ecological environment. Therefore, the rational recycling and utilization of waste tires, making full use of renewable resources and turning waste into treasure, is of great significance for improving the environment and building a conservation-oriented society.

[0003] Currently, rubber powder preparation is a core step in the resource utilization of waste tires. However, due to electrostatic adsorption and residual rubber adhesion, the rubber powder after tire shredding easily forms hard lumps, which cannot be effectively broken down by traditional vibrating screens. Setting up special crushing equipment to break down the lumpy rubber powder is a waste of production resources. Utility Model Content

[0004] In order to save production resources by breaking up agglomerated adhesive powder, this application provides a conveying device for adhesive powder pretreatment.

[0005] The conveying device for pretreatment of adhesive powder provided in this application adopts the following technical solution: A conveying device for pre-processing adhesive powder includes a support frame and a conveyor belt mounted on the support frame for conveying adhesive powder. A driven crushing mechanism is mounted on the support frame. The driven crushing mechanism includes two mounting frames fixedly connected to the support frame. A crushing cage is rotatably connected between the two mounting frames. The crushing cage includes multiple crushing rods.

[0006] By adopting the above technical solution, during the conveying process of the rubber powder, the rubber powder will pass through the crushing cage that is rotatably connected between two mounting frames. Multiple crushing rods on the crushing cage will come into contact with the clumped rubber powder. During the conveying process, the crushing cage will be rotated. As the crushing cage rotates, the crushing rods will continuously collide, squeeze and scrape the clumped rubber powder, thereby breaking the clumped rubber powder into smaller particles, realizing the pretreatment of the rubber powder. There is no need to provide a power source for the crushing cage, which saves production resources in crushing the clumped rubber powder.

[0007] Preferably, the crushing cage includes a rotating shaft rotatably connected between two mounting frames. Two mounting discs and an auxiliary disc are coaxially fixedly connected to the rotating shaft. The auxiliary disc is located between the two mounting discs and its diameter is larger than that of the mounting discs. A plurality of crushing rods are fixedly connected between each mounting disc and the auxiliary disc, and each crushing rod is inclined.

[0008] By adopting the above technical solution, the rubber powder can pass through multiple crushing rods during the conveying process. When it encounters agglomerated rubber powder, the agglomerated rubber powder drives the crushing cage to rotate, which can play a better crushing role on the rubber powder.

[0009] Preferably, both ends of the rotating shaft are rotatably connected to bearing seats, each bearing seat is vertically slidably connected to a corresponding mounting bracket, and the mounting bracket is connected to a locking element that locks the position of the bearing seat.

[0010] By adopting the above technical solution, the bearing housing and the mounting frame are vertically slidably connected, the height of the rotating shaft and the crushing cage can be adjusted, the locking component can lock the position of the bearing housing, ensuring the stability of the crushing cage during operation, and the distance between the crushing cage and the powder can be flexibly adjusted to improve the crushing effect.

[0011] Preferably, each of the mounting brackets has two elongated holes, and the locking element includes a screw that is inserted into each elongated hole. Each screw passes through an adjacent bearing seat and is threaded with a pair of locking nuts. The pair of locking nuts clamp the bearing seat and the mounting bracket.

[0012] By adopting the above technical solution, the bearing housing and the mounting bracket are clamped by a pair of locking nuts, which can lock the position of the bearing housing and make it easy to adjust the height of the crushing cage to adapt to different rubber powder processing needs.

[0013] Preferably, at least one fixing frame is also fixedly connected to the support frame, and a plurality of magnet blocks that contact the upper surface of the conveyor belt are fixedly connected to the fixing frame.

[0014] By adopting the above technical solution, during the conveying process of adhesive powder, the magnetic block fixed on the fixed frame and in contact with the upper surface of the conveyor belt can adsorb ferromagnetic impurities that may exist in the adhesive powder, thereby removing impurities from the adhesive powder and improving the purity of the adhesive powder.

[0015] Preferably, each of the magnet blocks is fixedly connected to a corresponding fixing frame by a rubber band.

[0016] By adopting the above technical solution, the adhesive powder will exert a force on the magnet block to move together during the conveying process. The rubber belt facilitates the magnet block to shuttle through the adhesive powder, and the rubber belt has a certain elasticity, a long service life and low cost.

[0017] Preferably, an auxiliary frame is fixedly connected to the support frame, and multiple chains are fixedly connected to the auxiliary frame, with a hook fixedly connected to the lower end of each chain.

[0018] By adopting the above technical solution, the hook can catch lightweight fibers such as nylon curtains, gloves left by operators, and plastic woven bags mixed in the adhesive powder, thereby improving the purity of the adhesive powder.

[0019] Preferably, each chain has multiple hooks fixedly connected to its lower end.

[0020] By adopting the above technical solution, it is easy to attach some lightweight fiber impurities, and the work efficiency is relatively high.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Crushing agglomerated rubber powder without requiring a power source for the crushing cage, thus saving production resources; 2. The distance between the crushing cage and the powder can be flexibly adjusted to improve the crushing effect; 3. It facilitates the removal of ferromagnetic impurities that may be present in the adhesive powder. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0027] This application discloses a conveying device for pre-processing adhesive powder. (Refer to...) Figure 1 and Figure 2 The conveying device for pre-processing rubber powder includes a support frame 1, a conveyor belt 2, and a driven crushing mechanism 3. The conveyor belt 2 is installed on the support frame 1 to convey rubber powder, and the driven crushing mechanism 3 is installed on the support frame 1 to crush the rubber powder during the conveying process.

[0028] The driven crushing mechanism 3 includes two mounting frames 31 fixedly connected to the support frame 1, with the conveyor belt 2 located between the two mounting frames 31. A crushing cage 32 is rotatably connected between the two mounting frames 31. The mounting frames 31 are usually made of metal, have good strength and stability, and can be fixed to the support frame 1 by welding or bolting.

[0029] The crushing cage 32 includes a rotating shaft 321 rotatably connected between two mounting brackets 31. Two mounting discs 322 and an auxiliary disc 323 are coaxially fixedly connected to the rotating shaft 321. The auxiliary disc 323 is located between the two mounting discs 322. Each mounting disc 322 is located at the end of the rotating shaft 321, and the diameter of the auxiliary disc 323 is larger than the diameter of each mounting disc 322. Several crushing rods 324 are fixedly connected between each mounting disc 322 and the auxiliary disc 323. The crushing rods 324 are evenly distributed around the rotating shaft 321, and each crushing rod 324 is inclined from the direction close to the auxiliary disc 323 to the direction away from the rotating shaft 321.

[0030] The connection between the crushing rod 324 and each mounting plate 322, and between the crushing rod 324 and each auxiliary plate 323, can be either welded or bolted, to facilitate the replacement and maintenance of the crushing rod 324. Alternatively, the crushing rod 324 can be replaced with a spiked crushing component; the spiked component has many protrusions on its surface to enhance the crushing effect.

[0031] During the process of conveying the adhesive powder by the conveyor belt 2, the clumped adhesive powder impacts the crushing cage 32 as it moves, causing the crushing cage 32 to rotate. The rotation of the crushing cage 32 will crush the clumped adhesive powder.

[0032] Reference Figure 1 and Figure 2 To facilitate the adjustment of the height of the crushing cage 32, both ends of the rotating shaft 321 are rotatably connected to bearing seats 33. Each bearing seat 33 is vertically slidably connected to the corresponding mounting frame 31. The mounting frame 31 is connected to a locking element 34 that locks the position of the bearing seat 33.

[0033] The bearing housing 33 is generally made of cast steel and houses the bearing to support the rotation of the shaft 321. Each mounting bracket 31 has two elongated holes 311, which are positioned away from the conveyor belt 2. The locking member 34 includes a screw 341 that inserts into each elongated hole 311. Each screw 341 passes through the adjacent bearing housing 33 and is threaded with a pair of locking nuts. The pair of locking nuts clamp the bearing housing 33 and the mounting bracket 31, thereby locking the bearing housing 33 and the mounting bracket 31 together.

[0034] When it is necessary to adjust the height of the crushing cage 32, the position of the bearing seat 33 can be adjusted and locked by tightening or loosening the locking nut.

[0035] To remove metallic impurities from the adhesive powder, multiple fixed frames 4 are fixedly connected to the support frame 1. Each fixed frame 4 is located directly above the conveyor belt 2, and multiple rubber belts 41 are fixedly connected to each fixed frame 4, distributed along the length of the fixed frame 4. A magnet 42 is fixedly connected to the lower end of each rubber belt 41. The magnet 42 overlaps the conveyor belt 2 and can remove metallic impurities from the adhesive powder. Reference Figure 1 and Figure 3 An auxiliary frame 5 is fixedly connected to the support frame 1, and multiple chains 51 are fixedly connected to the auxiliary frame 5, arranged along the length of the auxiliary frame 5. Multiple hooks 52 are fixedly connected to the lower end of each chain 51. The hooks 52 are connected to the chains 51 by welding or bolting. When the conveyor belt 2 is running, the hooks 52 can agitate the rubber powder, aiding in crushing and impurity removal. Simultaneously, the hooks 52 can catch fibrous impurities in the rubber powder, thereby removing larger fibrous impurities.

[0036] The implementation principle of the conveying device for pre-treatment of adhesive powder in this application embodiment is as follows: During the conveying process of adhesive powder, the crushing cage 32 rotates under the push of the agglomerated adhesive powder, crushing the adhesive powder without the need for an additional crushing process, thus reducing the complexity and cost of the production process. At the same time, the magnet block 42 can adsorb metallic impurities in the adhesive powder, and the hook 52 can remove fibrous impurities from the adhesive powder, improving the quality of the adhesive powder.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
