Description

Technical Field

[0001] The utility model relates to agricultural product processing equipment, in particular to an electric trolley for automatically retracting an empty rubber trolley of a natural rubber drying line. Background Art

[0002] Natural rubber is a high molecular compound. Due to its good properties such as plasticity, resilience, acid resistance and wear resistance, it is widely used in actual production. In recent years, with the rapid development of various industries, the role of natural rubber in aerospace, rail transportation and marine equipment has become increasingly important. As an important material resource and industrial raw material of the country, natural rubber is an important part of national development and security. Therefore, further promoting the rapid development of the natural rubber industry is a very important task at present.

[0003] The natural rubber primary processing drying line mainly includes three parts: loading, furnace loading, and rubber unloading. The empty rubber cart after unloading the rubber blocks will be recovered for reloading and furnace use. Only when these three links are smoothly connected can the production capacity of the natural rubber primary processing drying line be effectively exerted. At present, the distance between the unloading position and the loading position of each rubber factory is generally far. The empty rubber cart after unloading is manually pushed from the unloading station to the loading station. The labor intensity of the workers is relatively high, which makes it difficult to ensure the smooth connection of the three links. In order to improve the working efficiency of the natural rubber primary processing drying line and reduce the labor intensity of workers, our team has developed an electric trolley for automatically retracting empty rubber carts of the natural rubber drying line, which realizes the automatic retraction of the empty rubber cart, reduces the intensity of workers, ensures the smooth connection between the unloading process and the loading process, and further improves the working efficiency of the natural rubber primary processing production line. Summary of the invention

[0004] The utility model is an electric trolley for automatically retracting empty rubber carts in a natural rubber drying line. The invention of this equipment can automatically retract the empty rubber carts after unloading to the loading station, solving the problem of long-distance and high-frequency manual operations, reducing the manual operation intensity of the natural rubber primary processing drying line, making the drying line and the loading and furnace process smoothly connected, and further improving the work efficiency of the natural rubber primary processing production line.

[0005] The technical solution adopted by the utility model is: a frame is provided, a driving wheel and a driven wheel are provided at the lower part of the frame, a battery and a control cabinet are also provided on the frame, a front glue car detection photoelectric switch, a forward limit switch and a glue car pushing manipulator are provided at the front part of the frame, and a rear glue car detection photoelectric switch and a backward limit switch are provided at the rear part of the frame.

[0006] The driving wheel is also provided with a transmission shaft, the transmission shaft is provided with a reducer, and the reducer is connected to the power motor.

[0007] The control cabinet is provided with a battery power display, a power indicator light, a start button, a stop button, and a running indicator light.

[0008] Automatic working process: After the system is powered on, the power indicator light is on, press the start button, the running indicator light is on, the trolley starts to work, the power motor reverses, drives the transmission shaft through the reducer and then drives the driving wheel to rotate, so that the trolley retreats to the glue unloading station. When the rear glue trolley detection photoelectric switch detects an empty glue trolley (indicating that there is an empty glue trolley waiting to be recovered), the power motor stops; if the rear glue trolley detection photoelectric switch does not detect an empty glue trolley (indicating that there is no empty glue trolley waiting to be recovered), the power motor continues to reverse. When the trolley reaches the limit position of retreat, the retreat limit switch is activated, the power motor stops, and waits for the arrival of the empty glue trolley that has finished unloading. When the empty glue trolley that has finished unloading arrives, the rear glue trolley detection photoelectric switch detects that there is an empty glue trolley. After the glue cart (indicating that there is an empty glue cart that can be retrieved here), the glue cart pusher extends out and hooks the empty glue cart, then the power motor rotates forward, drives the transmission shaft through the reducer and then drives the driving wheel to rotate, so that the trolley pushes the empty glue cart to the loading station. When the front glue cart detection photoelectric switch detects that there is an empty glue cart, the power motor stops; if the front glue cart detection photoelectric switch does not detect that there is an empty glue cart, the power motor continues to rotate forward. When the trolley reaches the forward limit position, the forward limit switch is activated, the power motor stops, the glue cart pusher retracts, releases the empty glue cart, and then the power motor reverses, drives the transmission shaft through the reducer and then drives the driving wheel to rotate, so that the trolley retreats to the unloading station to transport the next empty glue cart.

[0009] The beneficial effect of the utility model is that the operation of retrieving the empty rubber truck after unloading the rubber to the loading station is fully automated, which solves the problem of long-distance and high-frequency manual operations, reduces the manual operation intensity of the natural rubber primary processing drying line, makes the drying line and the loading and furnace process smoothly connected, and further improves the work efficiency of the natural rubber primary processing production line.

DETAILED DESCRIPTION

[0014] The technical solution adopted by the utility model is as follows: a frame (1) is provided, a driving wheel (3) and a driven wheel (9) are provided at the lower part of the frame (1), a storage battery (13) and a control cabinet (8) are also provided on the frame (1), a front glue car detection photoelectric switch (12), a forward limit switch (10) and a glue car pusher (11) are provided at the front part of the frame (1), and a rear glue car detection photoelectric switch (2) and a backward limit switch (4) are provided at the rear part of the frame (1).

[0015] The driving wheel (3) is also provided with a transmission shaft (7), the transmission shaft (7) is provided with a reducer (6), and the reducer (6) is connected to the power motor (5).

[0016] The control cabinet (8) is provided with a battery (13) power indicator (18), a power indicator light (14), a start button (15), a stop button (16), and an operation indicator light (17).

[0017] Automatic working process: After the system is powered on, the power indicator light (14) lights up. When the start button (15) is pressed, the operation indicator light (17) lights up, the trolley starts to work, the power motor (5) reverses, drives the transmission shaft (7) through the reducer (6), and then drives the driving wheel (3) to rotate, so that the trolley retreats to the glue unloading station. When the rear glue trolley detection photoelectric switch (2) detects that there is an empty glue trolley (indicating that there is an empty glue trolley waiting to be retrieved), the power motor (5) stops; if the rear glue trolley detection photoelectric switch (2) does not detect that there is an empty glue trolley (indicating that there is no empty glue trolley waiting to be retrieved), the power motor (5) continues to reverse. When the trolley reaches the limit position of retreat, the retreat limit switch (4) is activated, and the power motor (5) stops, waiting for the arrival of the empty glue trolley that has finished unloading. When the empty glue trolley that has finished unloading arrives, the rear glue trolley detection photoelectric switch (2) detects that there is an empty glue trolley (indicating that there is no empty glue trolley waiting to be retrieved). After the empty rubber cart is retrieved, the rubber cart pusher (11) extends out to hook the empty rubber cart, and then the power motor (5) rotates forward, drives the transmission shaft (7) through the reducer (6), and then drives the driving wheel (3) to rotate, so that the trolley pushes the empty rubber cart to the loading station. When the front rubber cart detection photoelectric switch (12) detects that there is an empty rubber cart, the power motor (5) stops rotating; if the front rubber cart detection photoelectric switch (12) does not detect that there is an empty rubber cart, the power motor (5) continues to rotate forward. When the trolley reaches the forward limit position, the forward limit switch (10) is actuated, the power motor (5) stops rotating, the rubber cart pusher (11) retracts, and releases the empty rubber cart. Then the power motor (5) rotates reversely, drives the transmission shaft (7) through the reducer (6), and then drives the driving wheel (3) to rotate, so that the trolley retreats to the unloading station and carries out the transportation operation of the next empty rubber cart.
