Description

Technical Field

[0001] The invention belongs to the technical field of sponge cutting, in particular to a sponge cutting machine with an adjustable limiting mechanism. Background Art

[0002] Sponge is a porous elastic material with good water absorption and can be used to clean items. Sponges are mainly made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals. Synthetic sponges include low-density polyether, polyvinyl alcohol and polyester. Sponges are widely used in many industries, such as the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing industry and high-end furniture manufacturing industry. Sponges have good compressibility and resilience. During the clamping process, if the clamping force is too large, the sponge may be over-compressed, thus affecting the size and shape after cutting; if the clamping force is too small, the sponge may not be stably fixed, causing the sponge to move or shake during the cutting process. Some existing sponge cutting equipment may use a quick clamping mechanism for ease of operation, but this mechanism may not be able to adapt to sponges of all thicknesses and is not universal when clamping sponges for cutting.

[0003] For this purpose, a sponge cutting machine with adjustable limiting mechanism is proposed. Summary of the invention

[0006] Furthermore, the cutting mechanism includes a hydraulic cylinder, which is fixedly connected to the top inner wall of the U-shaped frame. A lifting column is installed on the lower surface of the hydraulic cylinder, and one end of the lifting column away from the hydraulic cylinder is fixedly connected to the U-shaped plate.

[0007] Furthermore, a motor 2 is fixedly connected to an inner wall on one side of the U-shaped plate, a screw rod 2 is fixedly connected to an output end of the motor 2, an end of the screw rod 2 away from the motor 2 is rotatably connected to the inner wall on the other side of the U-shaped plate via a bearing, and a threaded block is threadedly connected to an outer surface of the screw rod 2.

[0014] 2. In the present invention, when the cutting mechanism is used to cut the sponge, it is inevitable that debris and dust may be generated during the cutting. At this time, the vacuum pump can be started to pump the internal volume of the collection box. When the air inside the collection box is pumped to the outside, an air pressure difference will be generated between the inside and the outside of the collection box. At this time, the external air will move from the groove through the air guide tube to the lower internal volume of the collection box. At this time, the moving airflow will also drive the debris and dust generated during cutting into the lower internal volume of the collection box. The filter net can intercept the debris and dust entering the lower internal volume of the collection box to prevent these debris and dust from clogging the vacuum pump, thereby allowing these debris and dust to remain in the lower internal volume of the collection box for subsequent centralized treatment. The cooperation of the above structures can improve the working environment during sponge cutting.

[0015] 3. In the present invention, when the sponge to be cut is transported, one end of the sponge can be passed through two clamping rollers on the same side of the collection box, and then when one end of the sponge is pulled toward the U-shaped frame, the motor can be started to make the rotating rod drive the clamping roller to rotate, thereby providing support for the sponge and assisting the sponge to move, so as to facilitate subsequent cutting, thereby improving work efficiency.

[0016] 4. In the present invention, when cutting the sponge, the hydraulic cylinder can be started to make the lifting column drive the U-shaped plate to move downward until the saw blade approaches the upper surface of the sponge where the cutting position is required, and then the motor 2 can be started to rotate the screw rod 2. At this time, the threaded block will carry the saw blade to perform continuous horizontal reciprocating motion under the rotation of the screw rod 2, so as to cut the sponge.

At this time, the threaded block 57 will carry the saw blade 58 to perform continuous horizontal reciprocating motion under the rotation of the screw rod 2 56, so as to cut the sponge.

[0023] Reference Figure 1-Figure 5 A groove 11 is provided on the upper surface of the collecting box 1 just below the U-shaped frame 4, and a filter screen 13 is fixedly connected to the middle of the inner wall of the collecting box 1. The filter screen 13 divides the internal volume of the collecting box 1 into two parts, an upper and a lower part. The internal volume at the bottom of the groove 11 is connected with an air guide pipe 12. The end of the air guide pipe 12 away from the groove 11 passes through the filter screen 13 and extends to the lower internal volume of the collecting box 1. An air pump 14 is installed on the outer surface of one side of the collecting box 1, and the air inlet of the air pump 14 is connected to the upper internal volume of the collecting box 1. Specifically, when the sponge is cut by the cutting mechanism 5, it is inevitable that debris and dust may be generated during cutting. At this time, the air pump 14 can be started to clean the collecting box The internal volume of the collecting box 1 is pumped, and when the air inside the collecting box 1 is pumped to the outside, an air pressure difference will be generated between the inside and the outside of the collecting box 1. At this time, the external air will move from the groove 11 through the air guide pipe 12 to the internal volume of the lower end of the collecting box 1.

The cooperation of the above structures can improve the working environment during sponge cutting.

[0024] Reference Figure 1-Figure 5, the input ends of motor 1 22, motor 1 31 and motor 2 55 are electrically connected to the external power supply; specifically, the external power supply can provide power for starting motor 1 22, motor 1 31 and motor 2 55; the outer side wall of the internal cavity at the lower end of the collection box 1 is hinged with a sealing plate 15, and the outer surface of the sealing plate 15 is fixedly connected with a handle 16; specifically, when it is necessary to clean the debris and dust collected in the internal cavity at the lower end of the collection box 1, the sealing plate 15 can be opened by holding the handle 16 for centralized cleaning.

[0025] The implementation principle of the sponge cutting machine with adjustable limit mechanism in the present application is as follows: When using the cutting machine, first connect the external power supply. When cutting the sponge, you can first place the two ends of the sponge to be cut between the two clamping rollers 33, and make the middle part of the sponge pass through the U-shaped frame 4, then start the motor 22 to rotate the screw rod 23. At this time, the two movable plates 25 will approach each other under the rotation of the screw rod 23, and the movable plates 25 approaching each other will drive the two limit clamping mechanisms 3 on the same side to approach each other, so that the two clamping rollers 33 can fix and clamp sponges of different thicknesses to facilitate subsequent cutting. Through the cooperation of the above structure, sponges of different thicknesses can be positioned and clamped during cutting, thereby improving the universality of positioning and clamping the sponge.

[0026] When cutting the sponge, the hydraulic cylinder 51 can be started to make the lifting column 52 drive the U-shaped plate 53 to move downward until the saw blade 58 is close to the upper surface of the sponge where the cutting position is required. Then the motor 2 55 can be started to rotate the screw rod 2 56. At this time, the threaded block 57 will drive the saw blade 58 to perform continuous horizontal reciprocating motion under the rotation of the screw rod 2 56, so as to cut the sponge.

[0027] When the sponge is cut by the cutting mechanism 5, it is inevitable that debris and dust may be generated during the cutting. At this time, the vacuum pump 14 can be started to pump the internal volume of the collection box 1. When the air inside the collection box 1 is pumped to the outside, a pressure difference will be generated between the inside and the outside of the collection box 1. At this time, the external air will move from the groove 11 through the air duct 12 to the lower end internal volume of the collection box 1. At this time, the moving airflow will also drive the debris and dust generated during cutting into the lower end internal volume of the collection box 1, and the filter 13 can intercept the debris and dust entering the lower end internal volume of the collection box 1, so as to prevent these debris and dust from clogging the vacuum pump 14, and then make these debris and dust remain in the lower end internal volume of the collection box 1 for subsequent centralized treatment. The cooperation of the above structures can improve the working environment during sponge cutting.
