Description

Technical Field

[0001] This utility model relates to the technical field of plasticizing equipment, specifically to plasticizing equipment for sealing rubber parts. Background Technology

[0002] Rubber seals are generally round rubber products used for leak prevention. Natural rubber possesses high elasticity and slight plasticity at room temperature, exhibiting excellent mechanical strength, low hysteresis loss, and low heat generation during repeated deformation, resulting in good flexural resistance. Furthermore, as a non-polar rubber, it has good electrical insulation properties. Plasticizing equipment is used in the processing of sealing rubber parts.

[0003] Existing plasticizing equipment for sealing rubber parts typically uses smooth surfaces on the front and rear rollers. This means that the shearing action on the rubber compound mainly occurs at the roller gap, making it difficult for the compound to be fully sheared and folded internally. This results in uneven dispersion of compounding agents, affecting the physical properties of the seals. Furthermore, it fails to cut numerous small slits into the rubber compound before it enters the high-shear zone of the roller gap, creating a rough feed surface. This makes it difficult for the rubber compound to wrap around the rollers, affecting mixing efficiency and increasing energy loss. Therefore, there is an urgent need for plasticizing equipment for sealing rubber parts to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a plasticizing processing equipment for sealing rubber parts, in order to solve the problems mentioned in the background art. In the existing plasticizing processing equipment for sealing rubber parts, the surfaces of the front and rear rollers are usually smooth, so the shearing action on the rubber compound mainly occurs at the roller gap. It is difficult for the rubber compound to be fully sheared and folded inside, resulting in uneven dispersion of compounding agents and affecting the physical properties of the sealing parts. Secondly, it is impossible to cut numerous small cuts into the rubber compound before it enters the high-shear zone of the roller gap to form a rough feeding surface. This makes it difficult for the rubber compound to wrap around the rollers, affects the mixing efficiency, and increases energy loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plasticizing processing device for sealing rubber parts includes a base, with support frames connected to the upper left and upper right ends of the base. Support seats are connected to one side of each of the two support frames. A front roller is positioned between the two support frames, and a rear roller is positioned behind the front roller. The left ends of both the front and rear rollers pass through the left support frame and are each connected to a coupling. A motor mounting base is connected to one side of the left support frame. Two motors are symmetrically arranged on the top of the motor mounting base. The left ends of the two couplings are respectively connected to… The output shafts of the two motors are connected. A cutter shaft is provided diagonally above the rear roller. Both ends of the cutter shaft are connected to the support seats on both sides through bearings. A driven wheel is installed on the left end of the cutter shaft. The driven wheel is connected to the driving wheel through a chain. The driving wheel is installed on the output shaft of the motor. The surfaces of the front roller and the rear roller are provided with X-shaped raised mesh patterns. Baffle plates are provided above the left and right ends of the front roller and the rear roller. One side wall of the baffle plate is connected to one side wall of the support frame.

[0007] As a preferred embodiment of this utility model, the shape of the baffle plate is an arched bridge structure.

[0008] As a preferred embodiment of this utility model, the support base is L-shaped.

[0009] In a preferred embodiment of this invention, the diameter of the driven wheel is larger than the diameter of the driving wheel.

[0012] As a preferred embodiment of this invention, the cutter on the cutter shaft is located obliquely above the front roller and the rear roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model has X-shaped raised mesh patterns on the surfaces of both the front and rear rollers, which greatly enhances the shearing and tearing effect on the rubber compound and promotes the dispersion of compounding agents.

[0016] 2. This utility model, by setting up a support base, a cutter shaft, a driven wheel, a chain, and a driving wheel, utilizes the interaction between them to ensure that the rubber compound is cut into numerous small slits by the rotating cutter before entering the high-shear zone of the roller gap, forming a rough feeding surface. This makes the rubber compound easier to wrap around the roller, improves the mixing efficiency, and reduces energy loss. Attached Figure Description

It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0026] Please see Figure 1-6A plasticizing processing device for sealing rubber parts includes a base 1. Support frames 2 are connected to the upper left and upper right ends of the base 1. Support seats 3 are connected to one side of each support frame 2. A front roller 4 is positioned between the two support frames 2. A rear roller 5 is positioned behind the front roller 4. The left ends of the front roller 4 and the rear roller 5 pass through the left support frame 2 and are each connected to a coupling 7. A motor mounting seat 9 is connected to one side of the left support frame 2. Two motors 8 are symmetrically arranged on the top of the motor mounting seat 9. The left ends of the two couplings 7 are respectively connected to the output shafts of the two motors 8. A cutter shaft 10 is positioned diagonally above the rear roller 5. The left and right ends of the cutter shaft 10 are respectively connected to the support seats 3 on both sides via bearings. The left end of the cutter shaft 10... A driven wheel 11 is installed, which is connected to a driving wheel 6 via a chain 12. The driving wheel 6 is mounted on the output shaft of the motor 8. By utilizing their mutual cooperation, the rubber compound is cut into numerous small slits by a rotating cutter before entering the high-shear zone of the roller gap, forming a rough feed surface. This makes the rubber compound easier to wrap around the roller, improves the mixing efficiency, and reduces energy loss. The surfaces of the front roller 4 and the rear roller 5 are both provided with X-shaped raised mesh patterns 14. The X-shaped raised mesh patterns 14 greatly enhance the shearing and tearing effect on the rubber compound and promote the dispersion of compounding agents. Baffle plates 13 are provided above the left and right ends of the front roller 4 and the rear roller 5. One side wall of the baffle plate 13 is connected to one side wall of the support frame 2.

[0027] The baffle plate 13 has an arched bridge-like structure.

[0028] Among them, the support base 3 has an L-shaped structure.

[0029] The driven wheel 11 has a larger diameter than the driving wheel 6.

[0030] The motor mounting base 9 is located inside the support base 3.

[0031] There is a gap between the front roller 4 and the rear roller 5.

[0032] The cutter on the cutter shaft 10 is located diagonally above the front roller 4 and the rear roller 5.

[0033] The driven wheel 11 is fixedly connected to the cutter shaft 10.

[0034] The working principle and usage process of this utility model are as follows: Firstly, when processing sealing rubber parts, the two motors 8 located on the left side are started, directly driving the front roller 4 and rear roller 5 to rotate via two couplings 7. Simultaneously, the drive wheel 6 installed on the output shaft of the motor 8 transmits power to the driven wheel 11 via a chain 12, thereby driving the cutter shaft 10 on the driven wheel 11 to rotate. Multiple cutters installed on the cutter shaft 10 rotate accordingly. The operator feeds the block or strip-shaped rubber material for preparing the sealing rubber parts from above the equipment. The rubber material first falls into the area diagonally above the rear roller 5. Here, the cutters on the rotating cutter shaft 10 will... The falling rubber material is continuously and rapidly cut, creating numerous small slits on its surface to form a rough, cracked feed surface. Traditional rubber materials have smooth surfaces and tend to slip on the roller surface, making it difficult to effectively enter the roller gap. After pre-cutting, the friction between the rough rubber material surface and the roller surface is greatly increased, allowing the rubber material to be immediately gripped by the roller and quickly pulled into the roller gap between the front roller 4 and the rear roller 5. This completely solves the problem of difficult roller wrapping. Because the rubber material can be easily and quickly pulled into the roller gap, the motor does not need to output huge torque to overcome slippage, thus significantly reducing idling and energy loss and improving production efficiency.

[0035] The rubber material pulled into the roller gap first passes through the baffle plate 13. The baffle plate is designed as an arched bridge structure, which can effectively prevent the rubber material from overflowing from both ends of the roller and ensure that all materials enter the roller gap for processing. The rubber material enters the narrow gap between the front roller 4 and the rear roller 5, i.e. the roller gap. Usually, the two rollers will rotate relative to each other at different speeds, which will generate strong shearing and extrusion forces on the rubber material.

[0036] Unlike traditional smooth rollers or ordinary patterned rollers, the front and rear rollers of this equipment are processed with X-shaped raised mesh patterns 14. When the rubber compound passes through the roller gap, these raised X-shaped mesh patterns, like countless tiny scrapers, violently tear and stretch the rubber compound clumps. The interlaced X-shaped patterns can continuously cut, fold, and tumble the rubber compound, allowing all parts of the rubber compound to be fully and uniformly mixed. This powerful shearing and tearing action greatly destroys the macroscopic structure of the rubber compound, creating excellent conditions for the uniform dispersion of compounding agents such as carbon black and sulfur in the rubber compound at the microscopic level. This is the key to obtaining high-quality compounded rubber. After being subjected to high-intensity shearing and mixing through the roller gap, the rubber compound will emerge in sheet form directly below the area between the front roller 4 and the rear roller 5. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
