Description

Technical Field

[0001] This invention relates to the field of waste recycling and treatment technology, specifically to a device and method for recycling and treating waste automotive floor mats. Background Technology

[0002] Car floor mats are decorative accessories used to protect car carpets. Their main functions include protecting the carpet, preventing slipping and waterproofing, adding decorative flair, and facilitating cleaning. They are an essential accessory for vehicles. Car floor mat recycling is an important environmental protection industry. Properly recycling and disposing of used car floor mats after their lifespan is significant for environmental protection and resource reuse. Some car floor mats are flammable and can generate energy through recycling and burning, for example, as raw materials for waste-to-energy incineration. Implementing car floor mat recycling not only reduces resource waste and environmental pollution but also promotes the recycling of waste materials, achieving sustainable resource utilization and a circular economy.

[0003] A search revealed a novel waste recycling device for automotive parts production, with publication number CN213032593U. Its structure includes a foot pad, a crushing box, a discharge port, a feed port, a first motor, a power cord, a belt housing, a crushing shaft, and a collection device. This design utilizes a collection device located at the bottom of the crushing box. Workers first pour materials into the feed port, and the crushing shaft crushes the materials. The crushed materials fall into the collection box on the left for collection. When the collection box reaches a certain volume, gravity causes the first roller to press downwards via a spring and a telescopic support rod. Simultaneously, a connecting plate also presses down on the presser via a spring and the telescopic support rod. When the presser is pressed, an indicator light illuminates. Then, the worker activates the second motor, and the conveyor belt transports the left-side collection box to the outside of the crushing box, achieving the beneficial effect of collecting the crushed materials and improving worker efficiency.

[0004] If the car floor mat gets caught in the feed inlet when it is fed in, it will cause waste to accumulate. The equipment will not be able to tear up the suspended waste. In this device, once this problem occurs, it is necessary to frequently intervene manually to deal with the waste hanging in the feed inlet. The operator cannot focus on other tasks, and the frequent contact between the operator and the equipment will increase the safety risk between the operator and the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a recycling and processing device and method for automotive floor mat waste, which solves the problem that traditional recycling and processing devices require frequent manual intervention to handle waste hanging at the inlet, preventing operators from focusing on other tasks.

[0007] Four anti-suspension components are respectively disposed at the four edges of the feed hopper.

One end of the L-shaped connecting bar is fixed to the outside of the traction bar, the other end of the L-shaped connecting bar slides inside the vertical groove, and one end of the cylinder telescopic rod is fixed below the L-shaped connecting bar.

[0009] Preferably, the back of the device housing has two symmetrically arranged arc-shaped through slots, the inside of the device housing has two symmetrically arranged arc-shaped sliding grooves, and the two arc-shaped through slots are respectively opposite to the two arc-shaped sliding grooves. The back of the device housing is provided with security components.

[0010] Preferably, the security component includes a closure for sealing the equipment housing. The closure includes two arc-shaped covers located inside the equipment housing. A drive arm is fixed inside each of the two arc-shaped covers. One end of each drive arm slides inside the two arc-shaped through slots, and the other end of each drive arm slides inside the two arc-shaped sliding grooves. Two arc-shaped pieces are fixed to one side of each of the two arc-shaped covers, and a transition plate is fixed to one side of each of the two arc-shaped covers.

[0011] Preferably, the security component further includes a rotary member for changing the state of the two arc-shaped cover switches. The rotary member includes a closed shell fixed to the back of the device housing, two V-shaped angled arms, two connecting shafts, and a horizontal frame. The two V-shaped angled arms rotate inside the closed shell, and one end of each of the two V-shaped angled arms is fixedly connected to one end of each of the two drive arms. The two connecting shafts are fixed to the other ends of the two V-shaped angled arms, and both connecting shafts slide inside the horizontal frame.

[0012] Preferably, the security component further includes a levering component for driving the horizontal frame bar to rise and fall and automatically positioning it. The levering component includes two levering gears, two reversing gears, a double-sided rack and gravity plate, and two positioning anti-fall gears. An inner groove is provided below the double-sided rack and gravity plate, and the horizontal frame bar is fixedly connected to the double-sided rack and gravity plate.

[0013] The two lever gears and the two reversing gears are rotatably mounted on the back of the equipment housing. The two lever gears are fixedly connected to one end of the two crushing rollers via short shafts. The two reversing gears are located between the two lever gears and mesh with each other. The double-sided rack gravity plate slides inside the enclosed housing, and the two positioning anti-fall gears rotate inside the inner groove.

[0014] Preferably, the drive mechanism includes a motor, a small transmission wheel, a large transmission wheel, a reduction belt, and two transmission gears;

[0015] Both transmission gears rotate on the front of the equipment housing, and the two transmission gears are respectively fixedly connected to one end of the two crushing rollers via connecting shafts. The deceleration conveyor belt is sleeved between the small transmission wheel and the large transmission wheel. The large transmission wheel is fixed to the front of one of the transmission gears, and the small transmission wheel is fixed to one end of the motor output shaft.

[0016] Preferably, a support leg is fixed to the bottom of the device housing, and the motor is fixed to the front of the support leg by a support base.

[0017] Preferably, both sides of the device housing are provided with pull-out slots.

[0018] Preferably, the inner wall of the feed hopper is provided with support splicing grooves on both sides.

[0019] A method for recycling and processing waste car floor mats includes the following steps:

[0020] Step 1: Drive the two crushing rollers to rotate in opposite directions through the drive mechanism. The two crushing rollers drive the two lever gears to rotate accordingly. As a result, the two reversing gears rotate in the opposite direction and lift the double rack gravity plates and horizontal frame bars upward. The rise of the traction shaft causes the two V-shaped angled arms to deflect the two drive arms to the sides, thereby opening the two arc-shaped covers.

[0021] Step 2: The reversing gear moves up with the gravity plate of the double racks and meshes with the positioning anti-fall gear, so that the two transition plates are respectively attached to the two support splicing grooves. The reversing gear rotates continuously during the operation of the crushing roller and drives the positioning anti-fall gear to rotate continuously, so that the positioning anti-fall gear is kept at a certain height and the two arc-shaped covers are kept open.

[0022] Step 3: Discard the waste material into the feeding hopper. If the ultrasonic signal emitted by the ultrasonic transmitter is received by the ultrasonic receiver in less than the set time, it means that there is waste material hanging on the side of the feeding hopper. At this time, the PLC controller will control the cylinder at the corresponding feeding plate position. The cylinder will drive the L-shaped connecting bar and the drive bar to move upward. The drive bar pushes the feeding plate to deflect upward until the waste material slides down the feeding plate into the inside of the feeding hopper.

[0023] Step 4: When the equipment stops working, the lever gear stops rotating, and the double-sided rack gravity plate slides down under its own weight, driving the two reversing gears and the two lever gears to rotate several times until the two V-shaped angled arms return to the closed state of the two arc-shaped covers.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By calculating the time taken for the ultrasonic waves to return through the ultrasonic transmitter and receiver, it is determined whether there is waste material hanging on the edge of the feed hopper. After detecting the waste material hanging, the cylinder will drive the L-shaped connecting bar and the drive bar to move upward, thereby pushing the feeding plate to deflect upward. The waste material will slide down the feeding plate into the feed hopper and the inside of the equipment shell, saving manpower, allowing operators to focus on other tasks, and improving operational safety.

[0026] 2. By using two lever gears and two reversing gears, the double-sided rack and gravity plates and the horizontal frame are lifted upwards when the equipment is started. This causes the two V-shaped angled arms to deflect the two drive arms to the sides. The reversing gears rotate continuously with the crushing rollers. The positioning anti-fall gears are always kept at the same height due to their rotational meshing with the reversing gears. This ensures that the two arc-shaped covers remain open throughout the operation of the equipment. When the equipment stops, the double-sided rack and gravity plates reset under their own weight. This allows the two arc-shaped covers to open and close automatically with the equipment and does not require additional power. It also prevents small animals or children from entering when the equipment is stationary and avoids the impact of rain and snow on the service life of the crushing rollers of outdoor equipment.

[0040] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0041] This invention provides a technical solution: a device for recycling and processing waste automotive floor mats, such as... Figure 1 and Figure 5 As shown, the device includes a housing 1 and four anti-suspension components 5. Two crushing rollers 2 are rotatably installed inside the housing 1. A drive mechanism 3 is provided on the front of the housing 1. The drive mechanism 3 is used to drive the two crushing rollers 2 to work. A feed hopper 4 is fixed on the top of the housing 1. The feed hopper 4 is a quadrilateral shell. Waste car floor mats are put into the feed hopper 4 and slid into the housing 1 for crushing by being pulled by the inclined inner wall of the feed hopper 4. Both sides of the housing 1 are provided with pull-out grooves 10, and both sides of the inner wall of the feed hopper 4 are provided with support splicing grooves 11.

[0042] like Figure 1 , Figure 3 and Figure 5 As shown, the drive mechanism 3 includes a motor 31, a small transmission wheel 32, a large transmission wheel 33, a speed reduction conveyor belt 34, and two transmission gears 35. A support leg 9 is fixed to the bottom of the equipment housing 1. The motor 31 is fixed to the front of the support leg 9 through a support base. Both transmission gears 35 rotate on the front of the equipment housing 1, and the two transmission gears 35 are respectively fixedly connected to one end of the two crushing rollers 2 through connecting shafts. The speed reduction conveyor belt 34 is sleeved between the small transmission wheel 32 and the large transmission wheel 33. The large transmission wheel 33 is fixed to the front of one of the transmission gears 35, and the small transmission wheel 32 is fixed to one end of the output shaft of the motor 31. The motor 31 drives the large transmission wheel 33 to rotate through the small transmission wheel 32 and the speed reduction conveyor belt 34. The large transmission wheel 33 drives one of the transmission gears 35 connected to it to rotate, and the other transmission gear 35 rotates in the opposite direction, thereby driving the two crushing rollers 2 to rotate in the opposite direction.

[0043] like Figure 1 , Figure 2 and Figure 4As shown, four anti-suspension components 5 are respectively installed at the four edges of the feed hopper 4. The anti-suspension components 5 are used to prevent waste material from suspensing and accumulating on the edges of the feed hopper 4 when it is fed into the equipment housing 1. They monitor the waste material hanging on the edges of the feed hopper 4 and push it into the feed hopper 4, reducing the need for manual intervention, improving the automation level of the production line, saving labor and time costs, thereby improving production efficiency and quality. The anti-suspension components 5 include a positioning plate 51, a cylinder 52, a feeding plate 53, two traction bars 54, a drive bar 55, an L-shaped connecting bar 56, and an ultrasonic transmitter 57. The ultrasonic receiver 58 and the positioning strip 59 are provided, and the positioning plate 51 has a vertical groove 510 inside. Each anti-suspension component 5 is equipped with a PLC controller. The cylinder 52, ultrasonic transmitter 57 and ultrasonic receiver 58 are electrically connected to the PLC controller through existing technology. The propagation time of the ultrasonic signal is set, that is, the time it takes for the ultrasonic receiver 58 to receive the reflected wave after the ultrasonic transmitter 57 transmits the signal to the positioning strip 59. If this time changes, it means that there is waste material on the edge of the feeding plate 53 and the feeding hopper 4.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning plate 51 is fixed below the feed hopper 4, and the cylinder 52 is fixedly connected to the positioning plate 51 by a fixing hoop. The feeding plate 53 is rotatably installed at the edge of the feed hopper 4. When the telescopic rod of the cylinder 52 is not extended, the feeding plate 53 is in the following state: Figure 1 As shown, it will not hinder the input of waste material into the feed hopper 4. Both traction bars 54 are fixedly connected to the feeding plate 53, and the drive bar 55 slides between the two traction bars 54. One end of the L-shaped connecting bar 56 is fixed to the outside of the traction bar 54, and the other end of the L-shaped connecting bar 56 slides inside the vertical bar groove 510. Under the traction restriction of the vertical bar groove 510, the L-shaped connecting bar 56 can maintain the stability of lifting and lowering, and one end of the telescopic rod of the cylinder 52 is fixed below the L-shaped connecting bar 56.

[0045] like Figure 1 , Figure 2 and Figure 4As shown, when external workers throw waste into the feed hopper 4, if some waste material does not completely enter the feed hopper 4 but instead hangs on the edge of the feed hopper 4, the ultrasonic signal emitted by the ultrasonic transmitter 57 will return after encountering the waste material on the feeding plate 53 and the feed hopper 4. The ultrasonic receiver 58 will receive the reflected wave. The timing starts when the ultrasonic signal is emitted and stops when the ultrasonic receiver 58 receives the reflected wave. If the time is less than the set reception time, it means that the ultrasonic signal encountered the waste material and failed to transmit the emitted wave. Positioning bar 59. At this time, the time monitored by the PLC controller changes, and it will control the corresponding cylinder 52 telescopic rod to extend. The cylinder 52 will drive the L-shaped traction bar 56 to move upward. The L-shaped traction bar 56 pushes the drive bar 55 to push the feeding plate 53 to deflect upward under the restriction of the traction bar 54. The waste will slide down the feeding plate 53 into the feed hopper 4 and the inside of the equipment shell 1. There is no need for manual intervention to handle the waste hanging in the feed inlet. The operator can focus on other work tasks, reduce the frequency of operator contact with the equipment, and thus improve the operation safety.

[0046] like Figure 5-7 As shown, the back of the equipment housing 1 has two symmetrically arranged arc-shaped through slots 6, and the inside of the equipment housing 1 has two symmetrically arranged arc-shaped sliding grooves 7. The two arc-shaped through slots 6 are respectively opposite to the two arc-shaped sliding grooves 7. A safety component 8 is provided on the back of the equipment housing 1. The safety component 8 can block the opening of the feeding channel corresponding to the feeding hopper 4 when the equipment is turned on, and block the closing of the feeding channel corresponding to the feeding hopper 4 when the equipment is stopped. This can protect the main components inside the equipment from contamination and damage by dust, foreign objects, etc., extend the equipment life and reduce maintenance costs, and prevent small animals or rain and snow from entering the equipment when it is stationary outdoors. The safety component 8 includes a sealing member for closing the equipment housing 1. The sealing member includes two arc-shaped covers 81 located inside the equipment housing 1, such as... Figure 5 As shown, when the two arc-shaped covers 81 are closed, they are positioned above the two crushing rollers 2, respectively. Figure 7 As shown, when the two arc-shaped covers 81 are opened, they are located on both sides of the two crushing rollers 2. A drive arm 82 is fixed inside the two arc-shaped covers 81. One end of the two drive arms 82 slides inside the two arc-shaped through grooves 6 and extends through the arc-shaped through grooves 6 to the outside of the equipment housing 1. The other end of the two drive arms 82 slides inside the two arc-shaped slide grooves 7. Two arc-shaped pieces 83 are fixed on one side of the two arc-shaped covers 81. The arc-shaped pieces 83 can block part of the two arc-shaped through grooves 6 after the two arc-shaped covers 81 are opened, preventing the shredded waste from splashing out of the arc-shaped through grooves 6. A transition plate 84 is fixed on one side of the two arc-shaped covers 81.

[0047] like Figure 5-7As shown, the security component 8 also includes a rotary mechanism for changing the opening and closing states of the two arc-shaped covers 81. The rotary mechanism includes a closed shell 85 fixed to the back of the equipment housing 1, two V-shaped angled arms 86, two connecting shafts 87, and a horizontal frame strip 88. Both V-shaped angled arms 86 rotate inside the closed shell 85, and one end of each V-shaped angled arm 86 is fixedly connected to one end of each of the two drive arms 82. Figure 5 As shown, when the two arc-shaped covers 81 are closed, the arm on the V-shaped angled arm 86 with the connecting shaft 87 installed is in a straight state. The two connecting shafts 87 are respectively fixed to the other end of the two V-shaped angled arms 86, and both connecting shafts 87 slide inside the horizontal frame 88. The horizontal frame 88 is set in the closed shell 85 in the direction of sliding up and down.

[0048] like Figure 5-7 As shown, the security component 8 also includes a levering component for driving the horizontal frame bar 88 to rise and fall and automatically position it. The levering component includes two levering gears 89, two reversing gears 810, a double-sided rack and pinion gravity plate 811, and two positioning anti-fall gears 812. An inner groove 813 is provided below the double-sided rack and pinion gravity plate 811. The horizontal frame bar 88 is fixedly connected to the double-sided rack and pinion gravity plate 811. The two levering gears 89 and the two reversing gears 810 are rotatably mounted on the back of the equipment housing 1. The two levering gears 89 are fixedly connected to one end of the two crushing rollers 2 through short shafts. The two reversing gears 810 are located between the two levering gears 89, and the two reversing gears 810 mesh with the two levering gears 89 respectively. Figure 7 As shown, the double-sided rack and pinion plate 811 is located between the two reversing gears 810. The double-sided rack and pinion plate 811 slides inside the closed shell 85 and is restricted from sliding up and down. The two positioning anti-fall gears 812 rotate inside the inner groove 813. The position and tooth setting of the two positioning anti-fall gears 812 can automatically mesh with the reversing gear 810 when they correspond to it. The tooth distribution and diameter of the two lever gears 89, the two reversing gears 810 and the two positioning anti-fall gears 812 are the same.

[0049] like Figure 5-7As shown, after the equipment is turned on, the drive mechanism 3 drives the two crushing rollers 2 to rotate in opposite directions. The two crushing rollers 2 respectively drive the two lever gears 89 to rotate accordingly. The two lever gears 89 respectively drive the two reversing gears 810 to rotate in opposite directions. Under the meshing of the reversing gears 810 and their teeth, the double-sided rack and pinion gravity plates 811 are gradually lifted upward. The double-sided rack and pinion gravity plates 811 drive the horizontal frame bar 88 to move upward. The horizontal frame bar 88 then lifts one end of the two V-shaped angled arms 86 upward through the connecting shaft 87, thereby causing the two V-shaped angled arms 86 to deflect to the sides respectively. The other end of the two V-shaped angled arms 86 respectively drives the two drive arms 82 to deflect along the arc-shaped through groove 6, thereby opening the two arc-shaped covers 81 until the reversing gears 810 move upward with the double-sided rack and pinion gravity plates 811 and the positioning anti-fall gears 812 mesh. At this time, the two transition plates 84 are respectively attached to the two support splicing grooves 11. At the same time, the lever gear 89 always follows the rotation of the crushing roller 2, so the reversing gear 810 rotates continuously, and drives the positioning anti-fall gear 812 to rotate continuously. The positioning anti-fall gear 812 is always kept at a certain height under the rotation meshing of the reversing gear 810, thus keeping the double-sided rack gravity plate 811, the two V-shaped angled arms 86 and the two open arc-shaped covers 81 in position. When the equipment stops working, the lever gear 89 stops rotating, and the double-sided rack gravity plate 811 slides down under its own weight, driving the two reversing gears 810 and the two lever gear 89 to rotate several times until the two V-shaped angled arms 86 return to the closed state of the two arc-shaped covers 81, realizing that the two arc-shaped covers 81 automatically close when the equipment is closed.

[0050] A method for recycling and processing waste car floor mats includes the following steps:

[0051] Step 1: Drive mechanism 3 drives two crushing rollers 2 to rotate in opposite directions. The two crushing rollers 2 drive two lever gears 89 to rotate accordingly. As a result, two reversing gears 810 rotate in the opposite direction and lift the double rack gravity plates 811 and horizontal frame bars 88 upward. The rise of the connecting shaft 87 causes the two V-shaped angled arms 86 to deflect the two drive arms 82 to the sides, thereby opening the two arc-shaped covers 81.

[0052] Step 2: The reversing gear 810 moves upward with the double-sided rack gravity plate 811 and meshes with the positioning anti-fall gear 812, so that the two transition plates 84 are respectively attached to the two support splicing grooves 11. The reversing gear 810 rotates continuously during the operation of the crushing roller 2 and drives the positioning anti-fall gear 812 to rotate continuously, so that the positioning anti-fall gear 812 is kept at a certain height, and the two arc-shaped covers 81 are kept in the open state.

[0053] Step 3: Discard the waste material into the feed hopper 4. If the ultrasonic signal emitted by the ultrasonic transmitter 57 is received by the ultrasonic receiver 58 in less than the set time, it indicates that there is waste material hanging on the side of the feed hopper 4. At this time, the PLC controller will control the cylinder 52 at the corresponding feeding plate 53 position. The cylinder 52 will drive the L-shaped connecting bar 56 and the drive bar 55 to move upward. The drive bar 55 will push the feeding plate 53 to deflect upward until the waste material slides down the feeding plate 53 into the feed hopper 4.

[0054] Step 4: When the equipment stops working, the lever gear 89 stops rotating, and the double-sided rack gravity plate 811 slides down under its own weight, driving the two reversing gears 810 and the two lever gears 89 to rotate several times until the two V-shaped angled arms 86 return to the closed state of the two arc-shaped covers 81.

Both of the transmission gears (35) rotate on the front of the equipment housing (1), and the two transmission gears (35) are respectively fixedly connected to one end of the two crushing rollers (2) through connecting shafts. The deceleration conveyor belt (34) is sleeved between the small transmission wheel (32) and the large transmission wheel (33). The large transmission wheel (33) is fixed on the front of one of the transmission gears (35), and the small transmission wheel (32) is fixed to one end of the output shaft of the motor (31).

4. The automobile floor mat waste recycling and processing device as described in claim 3, characterized in that, A support leg (9) is fixed to the bottom of the device housing (1), and the motor (31) is fixed to the front of the support leg (9) by a support base.

5. The automobile floor mat waste recycling and processing device as described in claim 4, characterized in that, Both sides of the device housing (1) are provided with pull-out slots (10).

6. The automobile floor mat waste recycling and processing device as described in claim 5, characterized in that, The inner walls of the feed hopper (4) are provided with support splicing grooves (11) on both sides.

7. A method for recycling and processing waste car floor mats, characterized in that, The processing method, applied to the processing apparatus as described in claim 2 or 6, includes the following steps: Step 1: The drive mechanism (3) drives the two crushing rollers (2) to rotate in opposite directions. The two crushing rollers (2) drive the two lever gears (89) to rotate accordingly. As a result, the two reversing gears (810) rotate in opposite directions and lift the double rack gravity plates (811) and the horizontal frame bars (88) upward. The rise of the connecting shaft (87) causes the two V-shaped angled arms (86) to deflect the two drive arms (82) to the sides respectively, thereby opening the two arc-shaped covers (81). Step 2: The reversing gear (810) moves upward with the double-sided rack gravity plate (811) and meshes with the positioning anti-fall gear (812), so that the two transition plates (84) are respectively attached to the two support splicing grooves (11). The reversing gear (810) rotates continuously during the operation of the crushing roller (2) and drives the positioning anti-fall gear (812) to rotate continuously, so that the positioning anti-fall gear (812) is kept at a certain height, and the two arc-shaped covers (81) are kept open. Step 3: Throw the waste into the feed hopper (4). If the ultrasonic signal emitted by the ultrasonic transmitter (57) is received by the ultrasonic receiver (58) for less than the set time, it means that there is waste hanging on the side of the feed hopper (4). At this time, the PLC controller will control the cylinder (52) at the corresponding feeding plate (53). The cylinder (52) will drive the L-shaped connecting bar (56) and the drive bar (55) to move upward. The drive bar (55) will push the feeding plate (53) to deflect upward until the waste slides down the feeding plate (53) into the feed hopper (4). Step 4: When the equipment stops working, the lever gear (89) stops rotating, and the double rack gravity plate (811) slides down under its own weight, driving the two reversing gears (810) and the two lever gears (89) to rotate several times until the two V-shaped angled arms (86) return to the closed state of the two arc-shaped covers (81).
