Description

Technical Field

[0001] The utility model relates to a rubber extruder, belonging to the technical field of mechanical assembly auxiliary tooling. Background Art

[0002] During the assembly process of engineering machinery, vehicles, and other equipment, glue is often applied to lock threads. After each use, the remaining glue is squeezed out manually, but this is time-consuming and labor-intensive, leading to significant waste. Existing squeezers on the market often use a hose-pulling method, creating a squeeze effect as the hose passes through a narrow slit to squeeze out the glue. This method is inconvenient to operate, requires significant force to pull the hose out, and makes it difficult to squeeze out all the remaining glue.

[0003] The paste squeezer disclosed in Chinese patent CN214453316U utilizes a first squeezing roller and a second squeezing roller disposed between an upper plate frame and a lower plate frame. When the upper plate frame and the lower plate frame are clamped inward, the first squeezing roller and the second squeezing roller engage with each other, and the first squeezing roller rotates to squeeze the rubber tube, allowing the paste to be fully squeezed out. The squeezing method of the paste squeezer using a rotating pressure roller can effectively improve the efficiency of the squeezer and squeeze out the residual glue. However, the first squeezing roller is connected to the central shaft via a key transmission, and key slots need to be provided on the central shaft and the first squeezing roller. This requires high processing precision, high cost, and high assembly requirements, resulting in a relatively high overall cost of the paste squeezer.

[0004] Therefore, there is an urgent need for a low-cost glue squeezer to improve glue squeezing efficiency, prevent waste, and reduce usage costs. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a glue squeezer to improve glue squeezing efficiency, prevent waste, and reduce use costs.

[0006] The purpose of this utility model is achieved in this way:

[0007] A glue squeezer includes a first armrest and a second armrest hingedly connected at the ends and in a U-shape, a first roller and a second roller being rotatably arranged between the U-shaped arms of the first armrest and the second armrest, a driving shaft being rotatably arranged between the U-shaped arms of the first armrest, the first roller being mounted on the driving shaft, and a handle being provided at the end of the driving shaft; the cross section of the driving shaft is a polygonal structure that matches the cross section of the inner hole of the first roller, and the polygonal shaft hole cooperates to realize the driving shaft driving the first roller to rotate.

[0008] Furthermore, the cross section of the driving shaft is triangular, and the driving shaft as a whole is a triangular prism shaft. Correspondingly, the cross section of the inner hole of the first roller is also triangular, and the overall inner hole of the first roller is a triangular prism hole.

[0009] Furthermore, a pin is rotatably provided between the U-shaped arms of the second armrest, and the second roller is rotatably sleeved on the pin.

[0010] Furthermore, the surfaces of the first roller and the second roller are both provided with longitudinal serrations.

[0011] Furthermore, the outer diameters of the first roller and the second roller are not equal.

[0012] Furthermore, the hinge points of the first armrest and the second armrest are connected by rivets.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model sets a transmission connection between the first roller and the driving shaft in contact with a multi-prism surface, which provides reliable transmission torque and is simpler to manufacture, convenient to assemble, low in cost, high in glue extrusion efficiency, clean in glue extrusion, and low in use cost.

[0024] See also Figures 1 to 7The present invention relates to a rubber squeezer, comprising a first handrail 1 and a second handrail 2, both of which are hingedly connected at their ends by rivets 7 and are U-shaped. A first roller 6 and a second roller 5 are rotatably provided between the U-shaped arms of the first handrail 1 and the second handrail 2, respectively. A pin 4 is rotatably provided between the U-shaped arms of the second handrail 2, and the second roller 6 is rotatably mounted on the pin 4.

[0025] A driving shaft 3 is rotatably provided between the U-shaped arms of the first handrail 1, and the first roller 6 is mounted on the driving shaft 3. A handle is provided at the end of the driving shaft 3. The cross section of the driving shaft 3 and the cross section of the inner hole of the first roller 6 are polygonal structures that match each other, and the polygonal shaft hole cooperates to realize that the driving shaft 3 drives the first roller 6 to rotate. In this embodiment, the cross section of the driving shaft 3 is triangular, and the driving shaft 3 is a triangular prism shaft as a whole. Correspondingly, the cross section of the inner hole of the first roller 6 is also triangular, and the overall inner hole of the first roller 6 is a triangular prism hole. The polygonal shaft-hole matching structure makes the shaft and hole processing simpler and more convenient, with a high tolerance for processing accuracy. Assembly only requires a simple set, which greatly reduces the production cost.

[0026] The surfaces of the first and second rollers 6, 5, are each provided with longitudinal serrations to facilitate engagement and extrusion of the rubber hose 8, forcing the hose 8 to translate synchronously with the rotation of the first and second rollers 6, 5, achieving progressive rubber extrusion. Furthermore, if the outer diameters of the first and second rollers 6, 5 are unequal, the squeezed, flattened rubber hose 8 will deflect toward the roller with the smaller outer diameter, preventing it from interfering with the operator's grip on the first and second handrails 1, 2.

[0027] During operation, the first and second armrests 1 and 2 are opened, and the tail of the rubber hose 8 to be squeezed is placed between the first roller 6 and the second roller 5. The first and second armrests 1 and 2 are closed and a certain pressure is applied to generate an extrusion force between the first roller 6 and the second roller 5. At the same time, the handle is turned, and the driving shaft 3 drives the first roller 6 to rotate; under the extrusion force, the second roller 5 rotates following the first roller 6, and the rubber hose 8 is gradually squeezed and moved from the tail to the head of the rubber hose 8, completing the extrusion. The utility model has a simple structure, low manufacturing cost, easy assembly, high extrusion efficiency, clean extrusion, and low cost of use.

[0028] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
