Description

Technical Field

[0001] This utility model relates to the field of waste tire processing technology, specifically a waste tire crushing and feeding machine. Background Technology

[0002] With the rapid development of the automotive industry, the number of waste tires has increased dramatically. As a typical form of "black pollution," the disposal of waste tires has attracted increasing attention. Large accumulations of waste tires not only occupy valuable land resources but also easily breed mosquitoes and cause fires, posing a serious threat to the environment and public safety. Waste tire processing typically includes several stages such as preliminary crushing, magnetic separation, grinding, and screening. Among these, the crushing and feeding stage is the initial step in the entire process. Using a roller feeder, waste tires are fed into the subsequent processing equipment according to certain specifications and speeds for crushing.

[0003] In the process of conveying waste tires, traditional feeders often cause blockages during feeding because the tires are highly elastic and prone to slipping. As a result, the waste tires can easily get stuck on the roller feeder, affecting the feeding efficiency. Utility Model Content

[0004] This utility model provides a waste tire crushing and feeding machine, which has the advantage of being able to push tires with the assistance of a roller feeder through a pushing device, thereby avoiding tire slippage and improving feeding efficiency. This solves the problem that in the process of conveying waste tires by traditional feeders, the waste tires are easy to slip due to their high elasticity, which makes them easy to get stuck on the roller feeder, causing blockage during feeding and affecting feeding efficiency.

[0005] To achieve the goal of using a pushing device to assist the roller feeder in pushing tires, preventing tire slippage, and thus improving feeding efficiency, this utility model provides the following technical solution: a waste tire shredding feeder, including a roller feeder, and further including: multiple pushing devices disposed on both sides of the roller feeder, each pushing device including an adjusting frame, a pressure roller, a drive motor, and a height adaptation component; the adjusting frame is disposed on the side of the roller feeder, the drive motor is disposed on one side of the adjusting frame, the pressure roller is connected to the output shaft of the drive motor through the height adaptation component, and the height adaptation component is used to adjust the height of the pressure roller to the tire; height adjustment components are disposed on both sides of the roller feeder, the adjusting frame is disposed on the surface of the height adjustment component, and the height adjustment component is used to adjust the height of the adjusting frame.

[0006] As a preferred embodiment of this utility model, the height adaptation component includes a slider, a tripod, and a return spring. The slider is slidably fitted onto the surface of the adjustment frame. The slider is I-shaped. The drive motor is mounted on one side of the slider via a flange, and the tripod is on the other side of the slider. The output shaft of the drive motor passes through the slider and is fixedly connected to the tripod.

One end of the return spring is fixedly connected to the bottom of the slider, and the other end of the return spring is fixedly connected to the surface of the adjustment frame. A limit component is provided on the surface of the adjustment frame to limit the slider.

[0007] As a preferred embodiment of this utility model, the limiting component includes an infrared sensor and a locking component. The infrared sensor is fixedly mounted on the surface of the adjusting frame, and the locking component is mounted on the surface of the adjusting frame. Both the infrared sensor and the locking component are adapted to the number of adjusting frames, and the infrared sensor is electrically connected to the locking component.

[0008] As a preferred technical solution of this utility model, the locking assembly includes an electric push rod, a plug-in toothed plate, and an adapter toothed plate. The electric push rod is fixedly disposed on one side of the adjusting frame. A groove is provided on the inner side wall of the adjusting frame. The plug-in toothed plate is disposed in the groove. The telescopic shaft of the electric push rod passes through the adjusting frame and is fixedly connected to the plug-in toothed plate.

[0012] Compared with the prior art, this utility model provides a waste tire shredder feeder, which has the following beneficial effects:

[0013] This waste tire shredder and feeder, equipped with a pushing device, starts a drive motor that rotates a tripod in the opposite direction to the rollers of the roller feeder. The tripod drives three pressure rollers on its surface to rotate in a ring. Each roller then contacts the surface of the tire, generating friction and causing the rollers to rotate. The rollers push the tire forward, and the increased friction between the tire and the roller feeder, aided by the pushing device, prevents tire slippage and improves feeding efficiency. This addresses the problem of traditional feeders where waste tires, due to their high elasticity and slippage, easily get stuck on the roller feeder, causing blockages and affecting feeding efficiency.

[0019] 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.

[0020] Please see Figures 1-4This utility model discloses a waste tire shredding and feeding machine, including a roller feeder 1, and further including: multiple pushing devices disposed on both sides of the roller feeder 1, each pushing device including an adjusting frame 2, a pressure roller 3, a drive motor 4, and a height adaptation component. The adjusting frame 2 is disposed on the side of the roller feeder 1, the drive motor 4 is disposed on one side of the adjusting frame 2, and the pressure roller 3 is connected to the output shaft of the drive motor 4 through the height adaptation component. The height adaptation component is used to adjust the height of the pressure roller 3 to the tire; height adjustment components are disposed on both sides of the roller feeder 1, and the adjusting frame 2 is disposed on the surface of the height adjustment component. The height adjustment component is used to adjust the height of the adjusting frame 2.

[0021] Specifically, the height-adaptive components include a slider 5, a tripod 6, and a return spring 7. The slider 5 is slidably fitted onto the surface of the adjusting frame 2. The slider 5 is I-shaped. The drive motor 4 is mounted on one side of the slider 5 via a flange. The tripod 6 is on the other side of the slider 5. The output shaft of the drive motor 4 passes through the slider 5 and is fixedly connected to the tripod 6. Three pressure rollers 3 are arranged in an array and fitted onto the surface of the connecting shaft of the tripod 6. One end of the return spring 7 is fixedly connected to the bottom of the slider 5, and the other end of the return spring 7 is fixedly connected to the surface of the adjusting frame 2. A limit component is provided on the surface of the adjusting frame 2 to limit the slider 5.

[0022] In this embodiment, when tires of different sizes are conveyed simultaneously, when one of the pressure rollers 3 comes into contact with the tire, under the rotation of the tripod 6, one of the pressure rollers 3 squeezes the tire and lifts the tripod 6 upward. As a result, the tripod 6 drives the slider 5 to slide upward along the inner wall of the adjusting frame 2. At the same time, the slider 5 drives the return spring 7 to stretch elastically, so as to be able to adapt to tires of different sizes.

[0023] Specifically, the limiting component includes an infrared sensor 8 and a locking component. The infrared sensor 8 is fixedly mounted on the surface of the adjusting frame 2, and the locking component is mounted on the surface of the adjusting frame 2. Both the infrared sensor 8 and the locking component are adapted to the number of adjusting frames 2. The infrared sensor 8 is electrically connected to the locking component. The locking component includes an electric push rod 9, a plug-in toothed plate 10, and an adapter toothed plate 11. The electric push rod 9 is fixedly mounted on one side of the adjusting frame 2. A groove is provided on the inner side wall of the adjusting frame 2. The plug-in toothed plate 10 is mounted in the groove. The telescopic shaft of the electric push rod 9 passes through the adjusting frame 2 and is fixedly connected to the plug-in toothed plate 10. The adapter toothed plate 11 is fixedly mounted on one side of the slider 5. The plug-in toothed plate 10 can mesh with the adapter toothed plate 11.

[0024] In this embodiment, after the infrared sensor 8 on the adjusting frame 2 detects the tire, the controller controls the extension shaft of the electric push rod 9 to extend. The extension shaft of the electric push rod 9 drives the insertion tooth plate 10 to move, so that the insertion tooth plate 10 and the matching tooth plate 11 on the side of the slider 5 are inserted and engaged, thereby limiting the slider 5 and preventing the pressure roller 3 from elastically shaking when pushing the tire, thus improving the anti-slip effect on the tire. When the tire is removed from the pressure roller 3, the infrared sensor 8 can no longer detect the tire. Then, the controller controls the extension shaft of the electric push rod 9 to reset, canceling the limitation on the slider 5, and thus resetting under the elasticity of the reset spring 7.

[0025] Specifically, anti-slip strips 12 are fixedly provided on the surface of the pressure roller 3. Multiple anti-slip strips 12 are arranged in a ring around the pressure roller 3, and the anti-slip strips 12 are elastic.

[0026] In this embodiment, when the pressure roller 3 comes into contact with the tire, the anti-slip strip 12 on the surface of the pressure roller 3 is made of rubber, so that the anti-slip strip 12 can increase the friction between the pressure roller 3 and the tire and avoid slipping.

[0027] Specifically, the height adjustment assembly includes a sliding frame 13, a connecting plate 14, and a fixing assembly. The sliding frame 13 is fixedly installed on the side of the roller feeder 1, and the connecting plate 14 is slidably installed inside the sliding frame 13. Multiple adjustment frames 2 are fixedly installed on the surface of the connecting plate 14. The fixing assembly is used to fix the connecting plate 14. The fixing assembly includes a connecting seat 15, a protrusion 16, and a toggle part 17. A groove is opened on the side of the sliding frame 13. The connecting seat 15 is fixedly installed on the side of the connecting plate 14 and passes through the groove. The protrusion 16 and the toggle part 17 are integrally formed. The protrusion 16 passes through the shaft of the connecting seat 15 and is tightly fitted to the surface of the sliding frame 13.

[0028] In this embodiment, when the tires to be transported have large size differences, the height of the adjusting frame 2 can be adjusted to accommodate tires with larger size differences. During adjustment, the actuating part 17 is held and turned. The actuating part 17 will drive the protrusion 16 to rotate around the connecting seat 15, thereby disengaging the protrusion 16 from the surface of the sliding frame 13 and unlocking the connecting plate 14. Then, the connecting plate 14 is slid along the inner wall of the sliding frame 13, causing the connecting plate 14 to drive the multiple adjusting frames 2 on the surface to rise and fall. After adjusting to the appropriate position, the actuating part 17 is turned back to its original position, causing the actuating part 17 to drive the protrusion 16 to press against the surface of the sliding frame 13, making the protrusion 16 fit tightly against the sliding frame 13, thereby fixing the connecting plate 14 and completing the adjustment.

[0029] The working principle and usage process of this utility model are as follows: When crushing waste tires, the tires are first placed on the surface of the roller feeder 1. Then, the roller feeder 1 conveys the tires into the crusher for crushing. During the conveying process, the drive motor 4 starts and drives the tripod 6 to rotate. The tripod 6 rotates in the opposite direction to the rollers of the roller feeder 1. The tripod 6 drives the three pressure rollers 3 on its surface to rotate in a ring. Then, the three pressure rollers 3 contact the surface of the tire one by one. During the contact process, the pressure rollers 3 and the tire generate friction, causing the pressure rollers 3 to rotate. The pressure rollers 3 push the tire, and when the pressure rollers 3 squeeze the tire, the friction between the tire and the roller feeder 1 increases, preventing the tire from vibrating due to elasticity and making the tire conveying process more stable.

[0030] When tires of different sizes are conveyed at the same time, when one of the pressure rollers 3 comes into contact with the tire, under the rotation of the tripod 6, one of the pressure rollers 3 squeezes the tire and lifts the tripod 6 upward. As a result, the tripod 6 drives the slider 5 to slide upward along the inner wall of the adjusting frame 2. At the same time, the slider 5 drives the return spring 7 to stretch elastically, so as to be able to adapt to tires of different sizes.

[0031] After the infrared sensor 8 on the adjusting frame 2 detects the tire, the controller controls the extension shaft of the electric push rod 9 to extend. The extension shaft of the electric push rod 9 drives the insertion tooth plate 10 to move, so that the insertion tooth plate 10 and the matching tooth plate 11 on the side of the slider 5 are inserted and engaged, thereby limiting the slider 5 and preventing the pressure roller 3 from elastically shaking when pushing the tire, thus improving the anti-slip effect on the tire. When the tire is removed from the pressure roller 3, the infrared sensor 8 can no longer detect the tire. Then, the controller controls the extension shaft of the electric push rod 9 to reset, canceling the limitation on the slider 5, and thus resetting under the elasticity of the reset spring 7.
