Description

Technical Field

[0001] The utility model belongs to the technical field of rubber mixing processing, and specifically relates to a rubber cutting device for a rubber mixer. Background Art

[0002] Rubber, with its excellent elasticity and resilience, has become the cornerstone of modern industry and life, and is widely used in fields such as shock absorption, sealing, insulation, and the manufacture of elastic components. However, converting rubber raw materials into diverse products requires complex processing. As the core equipment, rubber mixers are responsible for tasks such as mixing, plasticizing, sheet pressing, and profiling.

[0003] However, with the booming development of the rubber product market, consumers' demands for product diversification and personalization are increasing day by day, which poses unprecedented challenges to the rubber processing industry. Specifically, traditional rubber cutting devices often adopt a fixed design, lacking sufficient flexibility and adjustability in terms of cutting size, shape, or angle. This "one-size-fits-all" mode is unable to cope when faced with diverse production demands. Different rubber products may require rubber sheets of different widths, cutting edges of different shapes, or bevel cuts at specific angles, while traditional rubber cutting devices often struggle to meet these meticulous cutting requirements. To meet these diverse needs, manufacturers have to replace with various specifications of rubber cutting dies or tools, which not only increases the preparation time and cost before production, but also brings operational complexity and inconvenience. Whenever a die or tool needs to be replaced, the machine has to be stopped, which undoubtedly reduces the overall production efficiency.

[0004] At the same time, frequent die replacement may also lead to an increase in errors, affecting the dimensional accuracy and appearance quality of products. More importantly, this limitation hinders the innovation and rapid iteration of rubber products, restricting enterprises from maintaining their advantages in the fierce market competition. The design concepts of new products are often unable to be quickly transformed into actual products due to the limitations in the rubber cutting process, affecting the market response speed and competitiveness of enterprises. Content of the Utility Model

[0005] To solve the problems raised in the above background art, the utility model provides a rubber cutting device for a rubber mixer.

[0006] To achieve the above object, the present utility model provides the following technical solution: A rubber cutting device for a rubber mixing machine, including a C-shaped frame, a transportation device, and a concave block. An electric push rod is fixedly installed at the inner top end of the C-shaped frame. There are two groups of the electric push rods. A rectangular shell is fixedly installed at the bottom of the two groups of electric push rods. A rectangular groove is opened at the bottom of the rectangular shell. A bidirectional lead screw is movably installed inside the rectangular groove. Two sets of socket blocks are movably installed on the surface of the bidirectional lead screw. A convex block is fixedly installed at the bottom of each of the two sets of socket blocks. A handle is fixedly installed on one side of the bidirectional lead screw. A cutting blade and a sleeve are sequentially fixedly installed at the bottom of the concave block. A trapezoidal block is movably installed inside the sleeve. A spring is arranged between the top of the trapezoidal block and the inner top end of the sleeve.

[0007] Preferably, a chute is opened on the inner wall of the C-shaped frame. A slider is fixedly installed on the side of the rectangular shell. The slider is movably installed inside the chute.

[0008] Preferably, four legs are fixedly installed at the bottom of the C-shaped frame. Leg pads are fixedly installed at the bottom of each of the four legs.

[0009] Preferably, the outer diameter value of the convex block is equal to the inner diameter value of the concave block. A rubber layer is arranged at the bottom of the trapezoidal block.

[0010] Preferably, the handle is circular in shape. A sponge layer is arranged on the surface of the handle.

[0011] Preferably, a reinforcing rib is arranged at the connection between the concave block and the cutting blade. The reinforcing rib is triangular in shape.

[0012] Preferably, the inner diameter value of the chute is equal to the outer diameter value of the slider. The slider is made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The utility model is clamped through the concave block and the convex block, and then the handle is rotated to make the two socket blocks move relatively, so that the two cutting blades also move synchronously. Then, the rubber sheet is placed on the surface of the transportation device and the transportation device is started. The transportation device transports the rubber sheet on its surface. At the same time, the electric push rod is started. The thrust of the electric push rod pushes the rectangular shell downward, and the trapezoidal block first contacts the surface of the rubber sheet and compresses the spring, so as to limit the rubber sheet. Then, the cutting blade contacts the rubber sheet and cuts it. Compared with the traditional device, this device can accurately adjust the distance between the two cutting blades, so as to cut rubber sheets with different widths according to actual needs, thereby improving the practicability of the device. At the same time, through the cooperation between the sleeve, the trapezoidal block and the spring, the cutting blade limits the rubber sheet before cutting it, so as to ensure the stability of the rubber sheet during cutting, and then can realize the uniform cutting of the rubber sheet, avoiding problems such as uneven cutting or burrs. And the contraction of the spring plays a certain buffering role in the cutting process, reducing the impact force of the direct contact between the cutting blade and the rubber sheet, thereby protecting the sharpness and service life of the cutting blade.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 5 shown, the present invention provides a rubber cutting device for a rubber mixing machine, including a C-shaped frame 1, a conveying device 2 and a concave block 10. An electric push rod 3 is fixedly installed at the inner top end of the C-shaped frame 1. There are two groups of electric push rods 3. A rectangular shell 4 is fixedly installed at the bottom of the two groups of electric push rods 3. A rectangular groove 5 is opened at the bottom of the rectangular shell 4. A bidirectional lead screw 6 is movably installed inside the rectangular groove 5. Two sets of socket blocks 7 are movably installed on the surface of the bidirectional lead screw 6. Convex blocks 8 are fixedly installed at the bottoms of the two sets of socket blocks 7. A handle 9 is fixedly installed on one side of the bidirectional lead screw 6. A cutting blade 11 and a sleeve 12 are fixedly installed in sequence at the bottom of the concave block 10. A trapezoidal block 13 is movably installed inside the sleeve 12. A spring 14 is arranged between the top of the trapezoidal block 13 and the inner top end of the sleeve 12;

[0023] Adopting the above solution: Through this device, the distance between the two cutting blades 11 can be accurately adjusted, so as to cut rubber sheets with different widths according to actual needs, thereby improving the practicability of the device. At the same time, through the cooperation between the sleeve 12, the trapezoidal block 13 and the spring 14, the cutting blade 11 is limited before cutting the rubber sheet, thereby ensuring the stability of the rubber sheet during cutting, and further enabling uniform cutting of the rubber sheet, avoiding problems such as uneven cutting or burrs. And the contraction effect of the spring 14 plays a certain buffering role during the cutting process, reducing the impact force of the direct contact between the cutting blade 11 and the rubber sheet, thereby protecting the sharpness and service life of the cutting blade 11.

[0024] As Figure 1 shown, a chute 16 is opened on the inner wall of the C-shaped frame 1. A slider 15 is fixedly installed on the side of the rectangular shell 4. The slider 15 is movably installed inside the chute 16. Four sets of legs 17 are fixedly installed at the bottom of the C-shaped frame 1. Leg pads 18 are fixedly installed at the bottoms of the four sets of legs 17;

[0025] Adopting the above solution: By opening a chute 16 on the inner wall of the C-shaped frame 1, fixedly installing a slider 15 on the side of the rectangular shell 4, and the slider 15 is movably installed inside the chute 16, the stability of the rectangular shell 4 during movement is improved. By fixedly installing four sets of legs 17 at the bottom of the C-shaped frame 1 and fixedly installing leg pads 18 at the bottoms of the four sets of legs 17, the stability of the device during use is improved.

[0026] As Figure 3 shown, the outer diameter value of the convex block 8 is equal to the inner diameter value of the concave block 10. A rubber layer is provided at the bottom of the trapezoidal block 13. The handle 9 has a circular shape, and a sponge layer is provided on the surface of the handle 9;

[0027] With the above solution: By setting the outer diameter value of the convex block 8 to be equal to the inner diameter value of the concave block 10, the clamping effect between the convex block 8 and the concave block 10 is better. A rubber layer is provided at the bottom of the trapezoidal block 13 to avoid damaging the surface of the rubber sheet. By making the handle 9 circular and providing a sponge layer on the surface of the handle 9, the comfort of the staff during use is improved.

[0028] As Figure 3 、 Figure 1 shown, a reinforcing rib 19 is provided at the connection between the concave block 10 and the cutting blade 11. The reinforcing rib 19 has a triangular shape. The inner diameter value of the sliding groove 16 is equal to the outer diameter value of the sliding block 15. The sliding block 15 is made of stainless steel;

[0029] With the above solution: By providing a reinforcing rib 19 at the connection between the concave block 10 and the cutting blade 11, the fixation between the concave block 10 and the cutting blade 11 is improved. The reinforcing rib 19 has a triangular shape, and a triangle has stability. By setting the inner diameter value of the sliding groove 16 to be equal to the outer diameter value of the sliding block 15, the sliding block 15 fits more closely when sliding inside the sliding groove 16. The sliding block 15 is made of stainless steel, which has high strength and good rust resistance.

[0030] The working principle and usage process of the present utility model:

[0031] During use, first, the concave block 10 is clamped inside the convex block 8 to complete the installation of the cutting blade 11. Subsequently, the staff rotates the handle 9 to make the bidirectional lead screw 6 rotate. Through the rotation of the bidirectional lead screw 6, the two socket blocks 7 on its surface move relatively, so that the two cutting blades 11 also move synchronously. After moving to an appropriate distance, the staff then places the rubber sheet on the surface of the transport device 2 and starts the transport device 2 to make the transport device 2 transport the rubber sheet. At the same time, the electric push rod 3 is operated through an external switch. The thrust of the electric push rod 3 pushes the rectangular shell 4 downward, and the trapezoidal block 13 first contacts the rubber sheet to make the spring 14 contract, thereby limiting the rubber sheet. Subsequently, the cutting blade 11 contacts the rubber sheet to cut the rubber sheet.
