Description

Technical Field

[0001] This utility model belongs to the field of rubber processing equipment, and relates to a rubber cutting equipment, and particularly to an automated rubber cutting equipment. Background Technology

[0002] In the rubber processing industry, strip cutting equipment is the core equipment for producing rubber strip products (such as tire cord layer rubber strips and medical catheter rubber strips). Its cutting accuracy and efficiency directly affect the product qualification rate and production cost. Currently, traditional rubber strip cutting equipment generally relies on manual adjustment of the pressure roller spacing and cutting parameters. After a single cut, the thickness error of the rubber strip generally exceeds ±0.3mm, and the width tolerance fluctuates within ±0.5mm. In the production of automotive sealing parts, the width tolerance of the rubber strip is required to be ≤0.1mm, but existing equipment requires 3-5 manual adjustments to barely meet the standard, resulting in a scrap rate as high as 25%-30%. Manual feeding and repeated calibration lead to poor production continuity, and the low degree of automation and lack of integrated control system mean that processes such as calendering, cutting, and material placement require multi-station manual intervention, resulting in high labor costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an automated rubber strip cutting device.

[0004] The purpose of this utility model can be achieved through the following technical solution: an automated rubber strip cutting device, characterized in that it includes a control system, a frame for supporting the main body of the device, and a feeding mechanism set on the frame for continuously conveying rubber materials;

[0005] The feeding mechanism includes a feeding box, a pressure roller device, and a cutting device;

[0006] The pressure roller device is installed inside the feed box and is used to perform thickness calendering of rubber materials;

[0007] The cutting device is located at the bottom of the feeding box and is used to cut the rubber material into widths.

[0009] The pressure roller device, cutting device, blade device, material placement device, conveyor belt device, and material handling mechanism are all connected to the control system and are controlled by it in a coordinated manner.

[0010] In the aforementioned automated rubber strip cutting equipment, the pressure roller device includes at least one pair of pressure rollers with adjustable spacing for controlling the thickness of the rubber material and a drive unit connected to the pressure rollers to drive their rotation.

[0011] In the aforementioned automated rubber strip cutting equipment, the cutting device includes two parallel cutting wheels located at the bottom of the feed box and an adjustment mechanism for adjusting the axial distance between the two cutting wheels to control the width of the rubber strip.

[0012] In the aforementioned automated rubber strip cutting equipment, the cutting device includes a drive motor, a cutting blade arranged perpendicular to the rubber material conveying direction, and a blade holder for fixing the cutting blade. The drive motor drives the cutting blade to perform periodic up-and-down movements through a crank-connecting rod mechanism.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, an automated rubber strip cutting device includes a control system, a frame 1 for supporting the main body of the device, and a feeding mechanism mounted on the frame 1 for continuously conveying rubber material. The feeding mechanism includes a feeding box 5, a pressure roller device 6, and a cutting device 7. The pressure roller device 6 is installed inside the feeding box 5 and is used for thickness calendering of the rubber material. The cutting device 7 is located at the bottom of the feeding box 5 and is used for width cutting of the rubber material. The automated rubber strip cutting device also includes a cutting blade device for equal-volume cutting of the calendered and cut rubber material, a material placement device 4 located downstream of the cutting blade device for orderly arranging the cut rubber strips, a conveyor belt device 2 for receiving and conveying the arranged rubber strips, and a material grabbing mechanism 3 for grabbing the rubber strips on the conveyor belt device 2. The pressure roller device 6, the cutting device 7, the cutting blade device, the material placement device 4, the conveyor belt device 2, and the material grabbing mechanism 3 are all connected to the control system and are controlled by it.

[0021] The above-mentioned structure is simple in design. Under the control of the control system, the feeding mechanism, cutting device, material placement device 4, conveyor belt device 2 and material picking mechanism 3 can accurately control the size of rubber materials and cut them into strip shapes in sequence. This greatly improves the accuracy of the strip size control and realizes automated and accurate cutting into strip shapes, reducing manual labor and improving dimensional accuracy and cutting efficiency.

[0022] To elaborate further, in order to precisely control the thickness of the rubber strip and achieve automation, the pressure roller device 6 includes at least one pair of pressure rollers 8 with adjustable spacing for controlling the thickness of the rubber material and a drive unit 9 connected to the pressure rollers 8 to drive their rotation.

[0023] To elaborate further, in order to accurately control the length of the adhesive strip and achieve automated cutting, the device 7 includes two parallel cutting wheels 10 located at the bottom of the feed box 5 and an adjustment mechanism for adjusting the axial distance between the two cutting wheels 10 to control the width of the adhesive strip.

[0024] The cutting device includes a drive motor 11, a cutting blade 12 arranged perpendicular to the conveying direction of the rubber material, and a blade holder 13 for fixing the cutting blade 12. The drive motor 11 drives the cutting blade 12 to move up and down periodically through a crank-connecting rod mechanism.

[0025] To elaborate further, in order to prevent the accumulation of adhesive strips and facilitate subsequent processes, the material placement device 4 includes a movable truss that can reciprocate along the conveying direction, a material placement component movably mounted on the movable truss and having a clamping part at its end, and a pin disposed on the clamping part of the material placement component for fixing the adhesive strip.

[0026] Work steps

[0027] S1: Place the rubber raw material / finished rubber roll into the feed box 5, and the pressure roller device 6 works to calender the rubber raw material / finished rubber roll into a rubber sheet.

[0028] S2: The rubber sheet after being calendered by the pressure roller device 6 passes between two cutting rollers. The cutting rollers can trim and cut the rubber sheet to control its length.

[0029] S3: The thickness and length of the rubber sheet after passing through the pressure roller device 6 and the cutting device 7 are both of the corresponding dimensions. The rubber sheet is then cut into rubber strips in equal quantities by the cutting device.

[0030] S4: The material handling device 4 moves the rubber strips in an orderly manner to the conveyor belt device 2, arranges them in sequence, and then moves them out through the conveyor belt device 2;

[0031] S5: Finally, the material handling mechanism 3 grabs the rubber strip and moves it to the next process.
