[0003] Patent application number 201310000384.2 discloses a long rubber cutting machine comprising a frame, with a blade shaft and a roller arranged in parallel from top to bottom. Both ends of the blade shaft and the roller are rotatably fixed to the frame. The blade shaft is uniformly distributed with multiple circular blades with outer cutting edges.

[0004] However, when using a traditional rubber cutting machine, when cutting small sections of rubber, the blades are narrow and the small sections of rubber after cutting are light in weight, so they are easily stuck between adjacent blades, thereby affecting the entire rubber cutting process. Utility Model Content

[0005] The utility model discloses an automatic weighing and cutting machine for rubber, which aims to solve the technical problem that, when a traditional rubber cutting machine is used, when cutting rubber into small sections, the distance between blades is narrow and the weight of the cut small sections of rubber is relatively light, so the sections are easily stuck between adjacent blades, thereby affecting the progress of the entire rubber cutting process.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A rubber automatic weighing and cutting machine comprises a workbench and side mounting frames mounted on the outer walls of both sides of the workbench, wherein the inner walls of both sides of the side mounting frames are symmetrically provided with second electric slide rails, and further comprises:

[0008] Cutting mechanism: The cutting mechanism includes a second slider and a fixed plate symmetrically mounted on the inner walls of the two second electric slide rails, a movable plate connected to the inner walls on opposite sides of the two second sliders, and blades arranged at equal distances mounted on the bottom outer wall of the movable plate. A knife cover is connected to the inner walls on opposite sides of the two fixed plates, and the inner wall of the knife cover is provided with partitions distributed at equal distances, the partitions are staggered with the blades, and a telescopic strip is connected between the knife cover and the movable plate;

[0009] Limiting mechanism: The limiting mechanism is arranged on the workbench.

[0010] In this solution, by setting up a second electric slide rail and a second slider, the knife holder with equally spaced blades can move up and down through the movable plate to perform a cutting function. By setting up a knife cover and an internal partition, the rubber strips adhered to the blade can be sprinkled off when the blade cuts the rubber and then moves upward. The fixed plate is fixed on the second electric slide rail and cannot be moved.

[0011] In a preferred solution, the limiting mechanism includes a cutting table and two symmetrical limiting plates arranged on the outer wall of the top of the workbench, fixed blocks are symmetrically arranged on the inner walls of one side of the two limiting plates, first electric slide rails are symmetrically opened on the inner walls of the two fixed blocks, first sliders are symmetrically installed on the inner walls of the two first electric slide rails, and brush strips are connected to the inner walls of the opposite sides of the two first sliders.

[0012] By setting up two symmetrical limit plates, the uncut rubber can be restricted on the cutting table when it reaches the cutting area, ensuring effective cutting. In addition, by setting up a first electric slide rail, the brush bar can be moved on the cutting table by utilizing the action of the first slider. After the cutting is completed, the cut rubber is brushed away, keeping the area above the cutting table clean and tidy, so as to facilitate the next cutting work.

[0013] In a preferred embodiment, a weighing box is provided on the top outer wall of the workbench, a weighing device is installed on the top outer wall of the weighing box, a display screen is provided on one side outer wall of the weighing device, and the bottom of the weighing box is lower than the cutting table.

[0014] By setting up a weighing box, when the brush bar sweeps the cut rubber into the weighing box, the scale on the weighing box can weigh it and display the weight on the display screen, which is helpful for the next step of work.

[0015] From the above, it can be seen that a rubber automatic weighing and cutting machine includes a workbench and side mounting frames installed on the outer walls of both sides of the workbench, the inner walls of both sides of the side mounting frames are symmetrically provided with second electric slide rails, and also includes: a cutting mechanism: the cutting mechanism includes second sliders and fixed plates symmetrically installed on the inner walls of the two second electric slide rails, the inner walls of the two second sliders on the opposite sides are connected with a movable plate, the bottom outer wall of the movable plate is installed with blades arranged at equal distances, the inner walls of the two fixed plates on the opposite sides are connected with a knife cover, the inner wall of the knife cover is provided with partitions distributed at equal distances, the partitions are staggered with the blades, and a telescopic strip is connected between the knife cover and the movable plate;

By setting up a knife cover 24 and an internal partition, the rubber strips adhered to the blade 14 can be scraped off when the blade 14 cuts the rubber and moves upward. The fixed plate 3 is fixed on the second electric slide rail 19 and cannot be moved.

[0027] The bottom outer wall of the side mounting frame 2 is connected to an electric telescopic rod 22 , and one end of the piston rod of the electric telescopic rod 22 is connected to the top outer wall of the movable plate 21 .

[0028] Specifically, by providing the electric telescopic rod 22, power can be provided to the movable plate 21 to enable it to move up and down.

[0029] Reference Figure 1 and Figure 4 In a preferred embodiment, the limiting mechanism includes a cutting table 12 and two symmetrical limiting plates 13 arranged on the top outer wall of the workbench 1, and fixed blocks are symmetrically arranged on the inner walls of one side of the two limiting plates 13.

Brush strips 18 are connected to the inner walls of the opposite sides of the two first sliders 17.

[0030] Specifically, by setting two symmetrical limit plates 13, the uncut rubber can be restricted on the cutting table 12 when it reaches the cutting area, ensuring effective cutting, and by setting a first electric slide rail 16, the first slider 17 can be used to move the brush bar 18 on the cutting table 12, and the cut rubber can be brushed away after the cutting is completed, keeping the area above the cutting table 12 tidy to facilitate the next cutting work.

[0031] A conveyor belt 4 is installed on one side of the top outer wall of the workbench 1, and the conveyor belt 4 is used to transport rubber.

[0032] Specifically, the uncut rubber can be automatically moved by providing the conveyor belt 4 and conveyed to the cutting table 12 for cutting, thereby replacing manual labor with the automation of the machine.

[0033] It should be noted that the limiting plates 13 provided in this solution can be adjusted relative to each other (not shown in the figure), so as to be adaptable to rubber materials of different sizes.

[0038] Specifically, by sequentially arranging the conveyor belt 4, the limiting plate 13 and the weighing box 10, a series of processes including conveying, cutting and weighing can be performed on the uncut rubber, with clear steps and efficient operation.

[0039] Working principle: When in use, the uncut rubber is transported to the position of the limit plate 13 by the conveyor belt 4, and the rubber will accurately reach the cutting table 12 according to the limit of the limit plate 13. At this time, the blade 14 in the area above the cutting table 12 will move down as the movable plate 21 slides on the second electric slide rail 19, cut the rubber and then move upward, compressed to the telescopic strip 25 connected to the knife cover 24 and the movable plate 21, and the knife cover 24 fixed on the fixed plate 3 combs the blade 14 through the internal partition, and sweeps off the rubber strip stuck to the blade 14. Next, the brush strip 18 connected to the first slider 17 will slide backward through the first electric slide rail 16, and sweep the cut rubber on the cutting table 12 into the weighing box 10 for weighing.
