Description

Technical Field

[0001] This utility model belongs to the technical field of rubber processing equipment, specifically a rubber cutting and conveying device with a protective structure. Background Technology

[0002] Rubber cutting and conveying equipment is widely used in industrial production. It achieves efficient processing of rubber materials through the coordinated operation of a feeding device, a cutting device, a protective device, and a discharging device. A search revealed a rubber cutting and conveying equipment with publication number CN106078828B, published on October 24, 2017. This design improves operator safety by installing an openable protective cover on the outside of the cutting device and reduces the probability of blade sticking during cutting by pressing and preheating the rubber to be cut. However, the opening method of the protective cover in this design is relatively fixed, making it difficult to flexibly adjust the protective angle or range according to specific working conditions in practical applications, potentially affecting operational convenience. Furthermore, the lack of effective collection measures for the debris and dust generated during cutting easily pollutes the working environment, thus affecting the long-term stable operation of the equipment and the health of operators.

[0003] Therefore, there is an urgent need to design a rubber cutting and conveying device with a protective structure to solve the problems of insufficient protective flexibility and debris and dust collection mentioned above. Utility Model Content

[0004] To address the problems mentioned in the background art regarding the fixed opening method of the protective cover in rubber cutting conveyor equipment, the difficulty in flexibly adjusting the protection angle or range, and the lack of effective collection measures for debris and dust generated during the cutting process, a rubber cutting conveyor equipment with a protective structure is provided. This equipment improves the flexibility of protection and the working environment by optimizing the design of the protective cover and adding a debris and dust collection device.

[0005] To achieve the above objectives, the specific technical solution of this utility model for a rubber cutting and conveying device with a protective structure is as follows:

[0006] A rubber cutting and conveying device with a protective structure includes a feeding mechanism, a cutting mechanism, a protective component, and a discharging mechanism. The protective component is located outside the cutting mechanism and includes an adjustable guard plate and a drive unit. The adjustable guard plate is connected to the drive unit, which is used to adjust the angle and position of the adjustable guard plate. A collection unit is provided below the protective component. The collection unit includes a guide plate and a dust collection box. The guide plate is inclined and one end is connected to the bottom of the protective component, while the other end extends to the inlet of the dust collection box. A filter screen is provided at the bottom of the dust collection box, and an exhaust fan is provided below the filter screen. The exhaust fan is connected to the dust collection box through a pipe.

[0007] Furthermore, the adjustable guard plate includes a first guard plate and a second guard plate, which are located on both sides of the cutting mechanism. The first guard plate and the second guard plate are connected to the frame by a hinge, and the hinge has a damping element embedded in it so that the first guard plate and the second guard plate can stay at any angle. The first guard plate and the second guard plate are provided with a magnetic sealing strip at the end away from the hinge. The magnetic sealing strip is used to form a tight connection when the first guard plate and the second guard plate are closed.

[0008] Furthermore, the drive unit includes an electric actuator and a hinge. One end of the electric actuator is fixed to the frame via the hinge, and the other end is connected to the first guard plate and the second guard plate, respectively. The electric actuator drives the first guard plate and the second guard plate to open or close synchronously.

[0009] Furthermore, the guide plate is fixedly connected to the bottom of the protective component, and an inclined guide groove is provided through the middle of the guide plate.

[0010] Furthermore, the dust collection box includes a box body and a cover plate. The cover plate is connected to the box body by a buckle. The cover plate is provided with an observation window made of transparent material, which is used to monitor the accumulation of debris in the dust collection box in real time. A dust discharge port is provided on one side of the box body, and a manual valve is provided at the dust discharge port. The manual valve is used to control the dust discharge operation.

[0011] Furthermore, the filter screen includes multiple filter elements, which, from top to bottom, consist of a coarse filter layer, a fine filter layer, and an activated carbon layer. The coarse filter layer is used to intercept large particles of debris, the fine filter layer is used to capture tiny particles, and the activated carbon layer is used to adsorb odors generated during the cutting process.

[0012] Furthermore, the exhaust fan includes a motor and a fan blade. The motor is fixed to the bottom of the dust collection box with bolts, and the fan blade is connected to the output shaft of the motor. When the fan blade rotates, it creates a negative pressure in the dust collection box. The negative pressure draws the debris and dust generated during the cutting process into the dust collection box through the guide plate.

[0013] Furthermore, the inner sides of the first and second guard plates are provided with a sound-absorbing layer, which is made of porous material and is used to absorb noise generated during the cutting process; the outer sides of the first and second guard plates are provided with anti-slip textures, which are used to facilitate operators to manually adjust the position of the guard plates.

[0014] Furthermore, the frame is equipped with a control panel, which is electrically connected to the electric push rod and the exhaust fan. The control panel is equipped with an adjustment knob and an indicator light. The adjustment knob is used to control the extension and retraction of the electric push rod, and the indicator light is used to display the working status of the exhaust fan.

[0015] Furthermore, both the feeding mechanism and the discharging mechanism are equipped with guide rollers. The surface of the guide rollers is covered with an elastic material, which is used to reduce frictional damage to the rubber material during the conveying process. The two ends of the guide rollers are connected to the frame through bearings, and the bearings are equipped with grease, which is used to reduce the frictional resistance when the guide rollers rotate.

[0016] The rubber cutting and conveying device with a protective structure of this utility model has the following advantages:

[0017] By installing an adjustable guard plate on the outside of the cutting mechanism and using a drive unit to flexibly adjust the angle and position of the guard plate, the protection range can be changed according to specific working conditions, thereby improving operational convenience and safety. By installing a guide plate and dust collection box below the protective components and combining them with an exhaust fan to form a negative pressure collection system, the debris and dust generated during the cutting process can be effectively collected, avoiding pollution to the working environment. By installing a sound-absorbing layer on the inside of the guard plate, the noise generated during the cutting process can be reduced, improving the operating environment. By installing multi-layer filter elements in the dust collection box, the sucked debris and dust can be filtered in stages, while odors can be absorbed to ensure the cleanliness of the exhaust air. By installing a control panel on the frame, centralized control of the equipment can be achieved, improving operational efficiency. Attached Figure Description

[0029] Example 1

[0030] This utility model discloses a rubber cutting and conveying device with a protective structure, comprising a feeding mechanism 1, a cutting mechanism 2, a protective component 3, and a discharging mechanism 4. These components are arranged on the frame in sequence according to the process flow. The protective component 3 is located outside the cutting mechanism 2 and connected to a collection unit 13, which is used to handle the debris and dust generated during the cutting process. The feeding mechanism 1 and the discharging mechanism 4 are respectively located on both sides of the cutting mechanism 2. The feeding mechanism 1 feeds the rubber material to be cut into the cutting mechanism 2, and the discharging mechanism 4 discharges the finished product after cutting. Both the feeding mechanism 1 and the discharging mechanism 4 are equipped with guide rollers 26. The surface of the guide rollers 26 is covered with an elastic material to reduce frictional damage during the conveying of the rubber material. The two ends of the guide rollers 26 are connected to the frame through bearings, and the bearings are filled with grease to reduce frictional resistance during rotation.

[0031] Both the feeding mechanism 1 and the discharging mechanism 4 include guide rollers 26, gears, idler wheels, drive shafts, generators, and frames. The drive shafts pass through and rotate on the frames. One end of the drive shaft is rotatably connected to the generator, and gears are provided at both ends of the drive shaft. The guide rollers 26 are arranged in the middle of each set of drive shafts, and the idler wheels are symmetrically arranged and mesh in the middle of the two sets of gears.

[0032] The protective assembly 3 includes an adjustable guard plate 5 and a drive unit 6. The adjustable guard plate 5 is connected to the frame via a hinge 9 and its angle and position are adjusted by the drive unit 6. The drive unit 6 includes an electric push rod 11 and a hinge. One end of the electric push rod 11 is fixed to the frame via the hinge, and the other end is connected to the first guard plate 7 and the second guard plate 8 respectively. The extension and retraction of the electric push rod 11 drives the first guard plate 7 and the second guard plate 8 to open or close synchronously.

[0033] The first guard plate 7 and the second guard plate 8 are provided with magnetic sealing strips 10 at the ends away from the hinge 9. When the two guard plates are closed, the magnetic sealing strips 10 attract each other to form a tight connection, preventing debris and dust from spilling out. The damping element embedded in the hinge 9 allows the first guard plate 7 and the second guard plate 8 to stay at any angle, meeting the protection requirements under different working conditions.

[0034] Example 2

[0035] Based on Embodiment 1, a collection unit 13 is added, which is located below the protective component 3.

[0036] The protective component 3 includes a guide plate 14 and a dust collection box 15. The guide plate 14 is inclined and one end is connected to the bottom of the protective component 3, while the other end extends to the inlet of the dust collection box 15. The guide plate 14 is divided into a first guide section and a second guide section, which are connected by a flexible connector 18. The flexible connector 18 allows for changes in the angle between the first guide section and the second guide section to adapt to changes in the installation position. The dust collection box 15 includes a box body and a cover plate 19. The cover plate 19 is connected to the box body by a snap fastener. The cover plate 19 has an observation window 20 made of transparent material for real-time monitoring of the debris accumulation in the dust collection box 15. A dust discharge port 21 is provided on one side of the box body, and a manual valve 22 is provided at the dust discharge port 21 for controlling the dust discharge operation. The dust collection box 15 has a filter screen 16 inside. The filter screen 16 includes multiple filter elements, from top to bottom: a coarse filter layer, a fine filter layer, and an activated carbon layer. The coarse filter layer is used to intercept large particles of debris, the fine filter layer is used to capture small particles, and the activated carbon layer is used to adsorb odors generated during the cutting process. The bottom of the dust collection box 15 is equipped with an exhaust fan 17, which includes a motor and a fan blade. The motor is fixed to the bottom of the dust collection box 15 by bolts, and the fan blade is connected to the output shaft of the motor. When the fan blade rotates, it creates a negative pressure inside the dust collection box 15. The negative pressure draws the debris and dust generated during the cutting process into the dust collection box 15 through the guide plate 14.

[0037] The inner sides of the first guard plate 7 and the second guard plate 8 are provided with sound-absorbing layers made of porous material to absorb noise generated during the cutting process. The outer sides of the first guard plate 7 and the second guard plate 8 are provided with anti-slip textures to facilitate manual adjustment of the guard plate positions by the operator. A control panel 23 is provided on the frame, which is electrically connected to the electric push rod 11 and the exhaust fan 17. The control panel 23 has an adjustment knob 24 and an indicator light 25. The adjustment knob 24 controls the extension and retraction of the electric push rod 11, and the indicator light 25 displays the working status of the exhaust fan 17. By rotating the adjustment knob 24, the operator can precisely control the extension and retraction of the electric push rod 11, thereby adjusting the angle and position of the first guard plate 7 and the second guard plate 8. When the indicator light 25 is lit, it indicates that the exhaust fan 17 is in working condition.

[0038] In actual use, the operator first starts the equipment via control panel 23 and places the rubber material to be cut on feeding mechanism 1. The drive motor on feeding mechanism 1 drives the gear to rotate via transmission shaft. The rotation of the gear drives the idler wheel to rotate, causing the guide roller 26 on the transmission shaft to smoothly feed the rubber material into cutting mechanism 2 for cutting. During the cutting process, the debris and dust generated are blocked by protective component 3 and guided into dust collection box 15 via guide plate 14. When the exhaust fan 17 is working, a negative pressure is formed in dust collection box 15. The negative pressure draws the debris and dust into dust collection box 15 through guide plate 14 and is filtered by multi-layer filter element before being discharged as clean air. When it is necessary to adjust the protection range, the operator can control the extension and retraction of electric push rod 11 via adjustment knob 24 on control panel 23. Electric push rod 11 drives the first guard plate 7 and the second guard plate 8 to open or close synchronously via linkage mechanism 12, thereby changing the protection range. When the first guard plate 7 and the second guard plate 8 are closed, the magnetic sealing strip 10 attracts each other to form a tight connection, preventing debris and dust from overflowing. The damping element embedded in the hinge 9 allows the first guard plate 7 and the second guard plate 8 to remain at any angle, meeting the protection requirements under different working conditions. The operator can monitor the accumulation of debris in the dust collection box 15 in real time through the observation window 20. When the debris accumulates to a certain level, the manual valve 22 is opened to discharge the debris through the dust discharge port 21.

[0039] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
