[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a unique pressure-relieving mechanism. A fan supplies air to the outlet pipe connected to the top cylinder of the pressure plate. The air pressure acts on a moving plate inside the cylinder, and combined with the elasticity of the second spring, allows the pressure roller to adaptively and elastically tighten according to changes in the pressure on the conveyor belt. Simultaneously, the structure on the outlet pipe, consisting of a fixed plate, a sliding plate, a top plate, and a first spring, further adjusts the air pressure, thereby more precisely controlling the pressure of the pressure roller on the conveyor belt. This design effectively avoids instability in the tension of the conveyor belt due to load changes, equipment vibration, and other factors, preventing conveyor belt slippage and deviation. It ensures stable and accurate transport of plastic products during automated assembly, greatly improving production efficiency and product quality.

[0015] 2. This utility model connects to the air outlet pipe via a connecting pipe. The vent holes on the outer surface of the roller can blow air onto the conveyor belt surface to achieve the cooling function. At the same time, the inner pipe with vent holes and the breathable membrane installed inside the roller, together with the motor-driven spiral impeller, can optimize the airflow distribution, making the blown air more uniform and effective, and further improving the cooling effect. In addition, the long strip-shaped cleaning sponge set on the outer surface of the roller can wipe the surface of the conveyor belt during the rotation of the roller to remove dust, impurities and plastic debris and other pollutants, so as to prevent these pollutants from contaminating plastic products or interfering with the operation of the assembly equipment.

[0016] 3. The limiting rubber strip fixedly installed on the inner wall of the conveyor belt of this utility model cooperates with the annular groove on the outer surface of the rotating shaft. During the operation of the conveyor belt, the limiting rubber strip slides in the annular groove, which increases the friction between the conveyor belt and the rotating shaft, effectively preventing the conveyor belt from slipping during transmission, improving the stability and reliability of transmission, and can meet the needs of long-term, high-intensity automated assembly production of plastic products. It reduces equipment failure and downtime, and further improves production efficiency and economic benefits. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a conveyor belt for automated assembly of plastic products, including a support frame 1, a conveyor belt 2 at the top of the support frame 1, a pressure relief mechanism 3 at the top of the support frame 1, a fan 31 installed at the top of the support frame 1, an air outlet pipe 32 connected to the output end of the fan 31, a pressure plate 310 on the inner surface of the conveyor belt 2, a pressure roller 311 for elastically fastening the conveyor belt 2 near the surface of the pressure plate 310, a cylinder 37 fixedly installed at the top of the pressure plate 310, a movable plate 38 slidably installed inside the cylinder 37, a second spring 39 fixedly installed between the movable plate 38 and the cylinder 37, the bottom end of the movable plate 38 connected to the top of the pressure roller 311 through a connecting rod, and the air outlet pipe 32 connected to the cylinder 37.

[0024] When the fan 31 is started, the airflow enters the cylinder 37 connected to the top of the pressure plate 310 through the air outlet pipe 32. The moving plate 38 inside the cylinder 37 moves up and down under the combined action of air pressure and the second spring 39, and then drives the pressure roller 311 to elastically fasten the conveyor belt 2 through the connecting rod. This can effectively adjust the tension of the conveyor belt 2, prevent the conveyor belt 2 from slipping due to insufficient tension or being damaged due to excessive tension, ensure the stable operation of the conveyor belt 2, improve the accuracy and reliability of plastic product conveying, and adapt to the conveying needs under different loads.

[0025] In some embodiments, a fixing plate 35 is fixedly installed on the outer surface of the air outlet duct 32, a sliding plate 36 is slidably installed inside the fixing plate 35, a through hole is opened on the outer surface of the sliding plate 36, a top plate 33 is fixedly installed on the top of the sliding plate 36, and a first spring 34 is fixedly installed between the top plate 33 and the wall of the air outlet duct 32.

[0026] When the pressure on the conveyor belt 2 is too high, the conveying surface of the conveyor belt 2 will deform. The deformed conveyor belt 2 will cause the slide plate 36 to move inside the fixed plate 35. This allows the air outlet pipe 32 to connect with the inside of the cylinder 37 through the through hole on the surface of the slide plate 36, thereby moving the pressure roller 311 and increasing the pressure on the conveyor belt 2. This allows for flexible adjustment of the air pressure entering the pressure relief mechanism 3, and more precise control of the pressure roller 311 on the conveyor belt 2. This further improves the accuracy and flexibility of the tension adjustment of the conveyor belt 2, and adapts to the tension requirements of the conveyor belt 2 under different working conditions.

[0027] In some embodiments, the surface of the support frame 1 is provided with an auxiliary mechanism 4, which includes a roller 42 rotatably mounted on the surface of the support frame 1 and the roller 42 slides on the outer surface of the conveyor belt 2. The inner cavity of the roller 42 is connected to the air outlet pipe 32 through a connecting pipe 41, and the outer surface of the roller 42 is provided with a plurality of vent holes 43 for cleaning and cooling the surface of the conveyor belt 2.

[0028] In this process, part of the airflow generated by the blower 31 enters the pressure-reducing mechanism 3, and the other part enters the roller 42 through the connecting pipe 41. It is then blown out from the vent holes 43 on the outer surface of the roller 42 and acts on the surface of the conveyor belt 2. On the one hand, it can clean the surface of the conveyor belt 2, blowing away dust and impurities and maintaining the cleanliness of the surface of the conveyor belt 2 to avoid contaminating plastic products. On the other hand, it can cool down the conveyor belt 2 to prevent the conveyor belt 2 from getting too hot due to long-term operation, which would affect the quality of plastic products and the service life of the conveyor belt 2.

[0029] In some embodiments, an inner tube 45 with vent holes 43 is installed inside the drum 42, and a breathable membrane 44 is provided between the drum 42 and the inner tube 45. A spiral impeller 46 is rotatably installed inside the drum 42, and a motor 47 is fixedly installed on the outer surface of the support frame 1. The output shaft of the motor 47 is fixedly connected to the spiral impeller 46.

[0030] When the airflow enters the drum 42, the motor 47 drives the spiral impeller 46 to rotate inside the drum 42. The rotation of the spiral impeller 46 causes the airflow to form a rotating flow inside the drum 42. The breathable membrane 44 can filter and evenly distribute the airflow, making the airflow blown out from the vent 43 more uniform and stable. This optimizes the airflow distribution, making the cleaning and cooling effects more uniform and effective, and improving the cleaning and cooling efficiency of the conveyor belt 2 surface. At the same time, the breathable membrane 44 can also filter impurities in the airflow, preventing impurities from clogging the vent 43 and ensuring the long-term stable operation of the auxiliary mechanism 4.

[0031] In some embodiments, a cleaning sponge is mounted on the outer surface of the roller 42, and the cleaning sponge is elongated.

[0032] Among them, a long strip of cleaning sponge is installed on the outer surface of the roller 42. When the roller 42 slides on the surface of the conveyor belt 2, the cleaning sponge comes into contact with the surface of the conveyor belt 2 and wipes away the stains and dust on the surface of the conveyor belt 2 through friction, which further enhances the cleaning effect of the surface of the conveyor belt 2. The long strip design can increase the cleaning area and improve the cleaning efficiency, effectively removing stubborn stains adhering to the surface of the conveyor belt 2, ensuring that the surface of the conveyor belt 2 is always kept clean, and providing a good environment for the conveying of plastic products.

[0033] In some embodiments, a baffle 7 is fixedly installed on the surface of the support frame 1 near the roller 42, and the cross section of the baffle 7 is arc-shaped.

[0034] During the operation of the conveyor belt 2, the baffle 7 can protect the roller 42 and the pressure roller 311. At the same time, the baffle 7 can guide the air outlet of the vent 43, preventing the downward-facing vent 43 on the surface of the roller 42 from blowing dust on the ground, which would cause the vent 43 on the surface of the roller 42 to become blocked, thus affecting the cleanliness and cooling of the surface of the conveyor belt 2.

[0035] In some embodiments, two rotating shafts 6 are rotatably mounted on the surface of the support frame 1, and the conveyor belt 2 is sleeved on the outer surface of the rotating shafts 6. A drive device 5 is fixedly mounted on the surface of the support frame 1, and the output shaft of the drive device 5 is fixedly connected to one of the rotating shafts 6.

[0036] When the drive device 5 is started, it drives the shaft 6 connected to it to rotate. The shaft 6 drives the conveyor belt 2 to move through friction, thereby realizing the conveying of plastic products. Its structure is simple and the transmission is reliable. It can provide stable power for the conveyor belt 2 and realize the continuous and automated conveying of plastic products. It is the core power transmission part of the entire conveyor belt system and ensures the efficient production.

[0037] In some embodiments, a limiting rubber strip for increasing the conveying friction of the conveyor belt 2 is fixedly installed on the inner wall of the conveyor belt 2, and an annular groove is opened on the outer surface of the rotating shaft 6, and the limiting rubber strip slides inside the annular groove.

[0038] When the conveyor belt 2 runs on the rotating shaft 6, the limiting rubber strip is embedded in the annular groove, which increases the friction between the conveyor belt 2 and the rotating shaft 6, preventing the conveyor belt 2 from slipping during transmission. This effectively improves the stability and reliability of the transmission of the conveyor belt 2, reduces the occurrence of slippage of the conveyor belt 2, ensures the accuracy and continuity of plastic product conveying, extends the service life of the conveyor belt 2 and the rotating shaft 6, and reduces equipment maintenance costs.

[0039] Working principle: When the pressure on the conveyor belt 2 is too high, the conveying surface of the conveyor belt 2 will deform. The deformed conveyor belt 2 will cause the slide plate 36 to move inside the fixed plate 35, thereby connecting the air outlet pipe 32 with the inside of the cylinder 37 through the through hole on the surface of the slide plate 36. When the fan 31 is started, the airflow enters the cylinder 37 connected to the top of the pressure plate 310 through the air outlet pipe 32. The moving plate 38 inside the cylinder 37 moves up and down under the combined action of air pressure and the second spring 39, and then drives the pressure roller 311 to elastically fasten the conveyor belt 2 through the connecting rod. This can effectively adjust the tension of the conveyor belt 2, prevent the conveyor belt 2 from slipping due to insufficient tension or being damaged due to excessive tension, and ensure the stable operation of the conveyor belt 2.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
