Description

Technical Field

[0001] This utility model relates to the field of rubber dispensing equipment technology, specifically to a rubber dispensing equipment and a rubber product processing system. Background Technology

[0002] In the manufacturing of rubber products, extrusion molding is a crucial and common processing technique. This process uses the rotating action of a screw to force disordered rubber material into a die in a spiral shape, thereby achieving a specific shape and size, ultimately forming the desired rubber product. This process is widely used in the production of many rubber products, such as tires, seals, and hoses.

[0003] However, in actual production processes, conventional molds present many problems that urgently need to be addressed in rubber extrusion. Among these, the most prominent is the instability of the inner and outer layer temperatures and the extrusion flow rate during rubber material extrusion.

[0004] Firstly, from a temperature perspective, the uneven temperature distribution between the inner and outer layers of rubber material results from varying degrees of heat generation due to friction between the rubber material and the mold wall and screw as it enters the mold under the screw's thrust. Differences in heat dissipation conditions within the mold further exacerbate this temperature imbalance. The inner layer of rubber material may be warmer due to friction with the screw and slower heat transfer, while the outer layer may be cooler due to faster heat dissipation from contact with the mold wall. This temperature unevenness directly affects the physical and chemical properties of the rubber. Warmer sections may undergo over-vulcanization, leading to increased hardness and decreased elasticity; conversely, cooler sections may be under-vulcanized, resulting in reduced strength and abrasion resistance. This not only affects the overall quality and performance of the rubber products but also makes it difficult to guarantee product consistency and stability.

[0005] Secondly, conventional molds also have significant drawbacks in terms of extrusion flow rate. The flow path of rubber material within the mold is complex, with varying resistance at different locations. Factors such as the mold's structural design, the shape and size of the flow channel all affect the flow of the rubber material. When the rubber material enters the mold from the screw, the sudden change in the flow channel causes a change in the material's flow rate. In certain narrow sections or bends of the mold, the flow rate of the rubber material will decrease significantly, forming localized stagnation areas; while in some wider sections, the flow rate may increase. This instability in flow rate leads to uneven distribution of the rubber material within the mold, resulting in problems such as inconsistent thickness and uneven surface of the extruded rubber products.

[0006] Unevenness in rubber extrusion can cause a series of problems in subsequent processing and use. During processing, uneven rubber products may require additional correction and treatment, which not only increases production costs and time but may also further affect product quality. In use, uneven rubber products may fail to meet actual application requirements, reducing product reliability and lifespan. Summary of the Invention

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0026] See Figures 1 to 3 As shown, this embodiment provides a rubber dispensing device, which includes: a dispensing module 100, the dispensing module 100 including a housing 110, the housing 110 having a through-flowing colloid flow channel, the colloid flow channel including a primary rectification and acclimatization chamber 120, a secondary rectification and acclimatization chamber 130 and a tertiary rectification and acclimatization chamber 140 connected in sequence in the direction of colloid flow, wherein the volume of the primary rectification and acclimatization chamber 120, the secondary rectification and acclimatization chamber 130 and the tertiary rectification and acclimatization chamber 140 decreases in sequence, the rubber to be processed flows from the primary rectification and acclimatization chamber 120 toward the tertiary rectification and acclimatization chamber 140, so as to buffer and homogenize it in the primary rectification and acclimatization chamber 120, the secondary rectification and acclimatization chamber 130 and the tertiary rectification and acclimatization chamber 140 respectively; and an adjustment mechanism 200, the adjustment mechanism 200 being connected to the housing 110 to drive the housing 110 to rotate around the rotation center line 1001.

[0027] In this embodiment, the dispensing module 100 is used to connect to the dispensing equipment and to output and shape the disordered flow of colloid in an orderly manner. Specifically, in this embodiment, the primary rectification chamber 120 is connected to the dispensing equipment and the colloid undergoes a first buffering and homogenization inside it. The secondary rectification chamber 130 receives the colloid output from the primary rectification chamber 120 and performs a second buffering and homogenization inside it. The tertiary rectification chamber 140 receives the colloid output from the secondary rectification chamber 130 and performs a third buffering and homogenization inside it. Thus, after three buffering and homogenization processes, the flow rate and overall temperature of the colloid are homogenized, thereby achieving the goal of improving its output stability and consistency.

[0028] See Figure 2 and Figure 3 As shown, the housing 110 in this embodiment includes a dispensing nozzle 112 and a body 111. The dispensing nozzle 112 is detachably connected to the body 111 and communicates with the interior of the body 111. The primary rectification chamber 120, the secondary rectification chamber 130, and part of the tertiary rectification chamber 140 are all disposed inside the body 111, while the remaining portion of the tertiary rectification chamber 140 is disposed within the dispensing nozzle 112. Furthermore, the body 111 serves as the main buffer and homogenization structure for conveying the adhesive. The dispensing nozzle 112 is detachably connected to the body 111, thereby allowing control of the dispensing shape by adjusting the dispensing nozzle 112 according to actual usage requirements. Specifically, in this embodiment, the primary rectification acclimatization chamber 120, the secondary rectification acclimatization chamber 130, and part of the tertiary rectification acclimatization chamber 140 are located in the body 111, and another part of the tertiary rectification acclimatization chamber 140 is located in the dispensing nozzle 112. Thus, when the dispensing nozzle 112 is connected to the body 111, the complete connection of the colloid flow channel can be achieved.

[0029] Furthermore, in this embodiment, the housing 110 includes a first mold 1111 and a second mold 1112 symmetrically arranged along its thickness direction. The first mold 1111 and the second mold 1112 are detachably connected, and together they enclose the primary rectification acclimatization chamber 120, the secondary rectification acclimatization chamber 130, and the tertiary rectification acclimatization chamber 140. Therefore, when cleaning the colloid flow channel is required, the first mold 1111 and the second mold 1112 can be disassembled to simplify the cleaning process. Correspondingly, when the first mold 1111 and the second mold 1112 are connected, they can re-enclose the respective rectification acclimatization chambers.

[0030] Furthermore, the dispensing nozzle 112 in this embodiment also includes a molding channel 1121, which is connected to the three-stage rectification and acclimatization chamber 140. The rubber to be processed flows from the first-stage rectification and acclimatization chamber 120 toward the third-stage rectification and acclimatization chamber 140 and is discharged through the molding channel 1121. Specifically, the molding channel 1121 in this embodiment is configured as a flat channel extending along the direction of colloid flow. In different embodiments, the specific size and shape of the molding channel 1121 can be adaptively adjusted according to actual usage requirements. This utility model does not impose specific limitations on this.

[0031] See Figure 3 As shown, the primary rectification and conditioning chamber 120 includes a first buffer space and a first flow guiding space sequentially arranged in the colloid flow direction. The first buffer space extends horizontally along a first direction, and the edge of the first flow guiding space gradually contracts from the first buffer space towards its center along the colloid flow direction. Further, the first buffer space is used to receive colloids with a rotation angle and a high flow rate. A large amount of colloid can be initially decelerated in the first buffer space and directionally transported through the first flow guiding space.

[0032] Correspondingly, the secondary rectification and acclimatization chamber 130 includes a second buffer space and a second flow guiding space. The second buffer space is connected to the primary rectification and acclimatization chamber 120, and the second flow guiding space extends horizontally along the flow direction of the colloid. The volume of the second buffer space is larger than that of the second flow guiding space. Specifically, in this embodiment, the secondary rectification and acclimatization chamber 130 is preferably a gourd-shaped structure, wherein the second buffer space is connected to the first flow guiding space, and its middle part protrudes outward to achieve a second buffering of the colloid entering its interior. Furthermore, the inner diameter of the second flow guiding space gradually narrows, thereby achieving directional guidance of the colloid in the second buffer space.

[0033] Similarly, the three-stage rectification and conditioning chamber 140 includes a third buffer space and a third flow guiding space. The third buffer space is connected to the second-stage rectification and conditioning chamber 130, and the third flow guiding space extends horizontally along the flow direction of the colloid. The volume of the third buffer space is larger than that of the third flow guiding space. The third buffer space has the same structure as the second buffer space, but its inner diameter is smaller. The third flow guiding space is connected to the forming channel 1121, thereby enabling the extrusion of the fully homogenized colloid.

[0034] In this embodiment, the adjustment mechanism 200 includes a support frame 210 and a driver 220. The two sides of the housing 110 in the thickness direction are rotatably connected to the working ends of the support frame 210 and the driver 220, respectively. The driver 220 is mounted on the support frame 210 to drive the dispensing module 100 to rotate around the rotation center line 1001. The support frame 210 provides an installation platform for the dispensing module 100 and the driver 220. The driver 220 is preferably a linear motor. Two connecting protrusions 113 are fixed on the upper surface of the housing 110 of the dispensing module 100. The driver 220 and the support frame 210 are rotatably connected to the two connecting protrusions 113. In actual use, the operator can adjust the actual working angle of the dispensing module 100 by controlling the extension and retraction of the working end of the driver 220, thereby improving the flexibility and applicability of this dispensing equipment. Example 2

[0035] This embodiment provides a rubber product processing system, which includes the rubber dispensing equipment described in Embodiment 1.

[0036] In summary, the rubber dispensing equipment and rubber product processing system described in this utility model, by setting a primary rectification and acclimatization chamber 120, a secondary rectification and acclimatization chamber 130, and a tertiary rectification and acclimatization chamber 140 connected in sequence in the dispensing module 100, achieves multiple buffering processes during the colloid flow process. The disordered colloid can have its flow rate and temperature homogenized in any rectification and acclimatization chamber, thereby ensuring the consistency and stability of the rubber after dispensing. Simultaneously, the adjustment mechanism 200 can also adjust the dispensing angle to broaden its applicability. Compared with conventional dispensing technologies, this application has advantages such as flexible use, easy control, stable dispensing quality, and continuous processing capability, and has broad application prospects in the industry.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
