Description

Technical Field

[0001] The utility model relates to the technical field of rubber powder anti-blocking, in particular to a rubber powder grinding machine for production that can prevent blockage. Background Technique

[0002] Rubber powder is a powdery substance processed from waste rubber. Common processing methods include normal temperature pulverization method, freezing method and normal temperature chemical method. Rubber powder is widely used in sports plastic playgrounds, playgrounds, rubber floor tiles, waterproof coiled materials, waterproof coatings, highway modified asphalt, rubber products and other fields. During the production process of rubber powder, the anti-blocking performance of the grinding machine is crucial to ensure the continuous and stable operation of the production line and reduce maintenance costs.

[0003] For example, a rubber powder grinding machine for production disclosed in Chinese Patent CN220946217U, through the combined use of a cross bar structure and a brush piece structure. During operation, the right side position at the bottom of the inner cavity of the first strip groove is higher than the left side position at the bottom of the inner cavity of the first strip groove, the bottom position of the inner cavity of the first strip groove is higher than the top position of the filter plate, and the top edge of the filter plate is designed as an inverted slope. The shape and size of the filter plate match the shape and size of the cross section of the inner cavity of the box body. Thus, when the cross bar resets to the left, due to the position of the bottom of the inner cavity of the first strip groove, the raw materials remaining on the surface of the filter plate will not leave the top of the filter plate, achieving the effect of preventing some rubber powder from not being screened.

[0004] For this structure, although the filter plate can be prevented from being blocked by the brush, during the use of the brush, rubber powder is easily attached to its interior, and over time, the dredging effect of the brush is affected. Therefore, we propose a rubber powder grinding machine for production that can clean the rubber powder attached to the brush to improve the anti-blocking effect of the filter plate. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rubber powder grinding machine for production that can prevent blockage, so as to solve the problems put forward in the above background technique.

[0008] Preferably, the auxiliary component includes a transmission mechanism sleeved on the outer wall of the reciprocating screw, a rotating rod is sleeved inside the transmission mechanism, an elliptical cylinder is fixedly mounted on the outer wall of the rotating rod, a slider is fixedly mounted on the inner wall of the box body, and a filter plate is slidably mounted on the outer wall of the slider.

[0009] Preferably, the end of the brush plate is arranged in an arc surface, and the outer wall of the protrusion is arranged in an arc surface. Under their restriction, when the brush plate and the protrusion are in contact and extrusion, the brush plate and the protrusion arranged in an arc surface can make the extrusion smoother.

[0010] Preferably, one end of the spring is fixedly mounted on the inner wall of the movable plate, and one end of the spring away from the inner wall of the movable plate is fixedly mounted on the outer wall of the limit block. Under the elastic action of the spring, when the brush plate is not squeezed, the brush plate is reset and pushed.

[0011] Preferably, there are eight protrusions which are equidistantly distributed inside the box body. Under the restriction of the protrusions, the brush plate can be squeezed when the brush plate slides therewith.

[0012] Preferably, the end of the limit rod is fixedly installed on the inner wall of the box, the sleeve block is movably sleeved with the reciprocating screw, and the limit ring is slidably arranged on the outer wall of the limit rod.

[0013] Preferably, holes are opened at equal intervals inside the filter plate, and the outer wall of the filter plate is slidably arranged with the inner wall of the box body, so that the rubber powder can be screened under the restriction of the filter plate.

[0014] Preferably, there are four sliders, which are divided into two groups and are symmetrically distributed about the center line inside the box. Under the restriction of the sliders, the filter plate can slide stably.

[0015] Preferably, the elliptical cylinder is elliptical in shape, and the rotating rod is connected to the reciprocating screw through a transmission mechanism. Under the restriction of the transmission mechanism, when the reciprocating screw rotates, the rotating rod can be driven to rotate accordingly, so that the rotating rod drives the elliptical cylinder to push and squeeze the bottom of the filter plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The rubber powder grinding machine for preventing blockage, which has a cleaning component as one of its parts. When anti-blocking treatment of rubber powder is required, the motor is started, and the reciprocating lead screw fixedly installed at the output end thereof starts to rotate. Since the limiting ring is slidably arranged on the outer wall of the limiting rod, under the limitation of the limiting rod, the rotating reciprocating lead screw can drive the sleeve block to reciprocate inside the box body. The sleeve block drives the moving plate to move accordingly, the moving plate drives the limiting block to move accordingly, and the limiting block drives the spring to move on the top surface of the filter plate to evenly spread the rubber powder and prevent it from blocking in the filter plate. When the brush plate brushes the filter plate, rubber powder is likely to adhere to its inside. When the moving plate drives the limiting block and the brush plate to move, the arc surface at the end of the brush plate contacts and presses against the convex block fixedly installed on the inner wall of the box body, causing the brush plate to drive the limiting block to slide under the moving plate, and the limiting block compresses the spring. When the brush plate no longer contacts and presses against the convex block, at this time, under the elastic action of the spring, it pushes the limiting block to reset, reciprocatingly polarizing the brush plate to shake off the rubber powder adhering to its inside, and cooperating with the push rod to perform anti-blocking treatment on the inside of the filter plate (the box body, the crushing mechanism and the push rod are existing public technologies in the comparative document, so their structures are not fully described in this case).

[0018] 2. The rubber powder grinding machine for preventing blockage, which has an auxiliary component as one of its parts. When the filter plate filters rubber powder, it is likely to be blocked inside. At this time, when the reciprocating lead screw rotates, it drives the rotating rod to rotate through the transmission mechanism, and the rotating rod drives the elliptical cylinder fixedly installed on its outer wall to rotate accordingly. The elliptical cylinder presses against the bottom of the filter plate, causing the filter plate to slide on the outer wall of the slider. When the elliptical cylinder no longer presses against the bottom of the filter plate, under the action of gravity, the filter plate slides downward on the outer wall of the slider, reciprocatingly vibrating the filter plate to perform anti-blocking treatment. Since the bristles at the bottom of the brush plate are made of soft material, under its limitation, the upward moving filter plate will not get stuck with the brush plate.

[0026] For a clearer understanding of the technical features, purposes, and effects of the present utility model, the specific implementation mode of the present utility model will now be described with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] A preferred embodiment of a rubber powder production grinding machine capable of preventing blockage provided by the present utility model is as Figures 1 to 6 shown: A rubber powder production grinding machine capable of preventing blockage, including a box body 1;

[0029] A crushing mechanism 2 is arranged on the upper part of the box body 1;

[0030] A control panel 3 is fixedly installed on the top surface of the box body 1;

[0031] And a processing component 4 arranged below the crushing mechanism 2. The processing component 4 includes a cleaning component 41 arranged below the crushing mechanism 2. The cleaning component 41 includes a bracket 411 fixedly installed on the outer wall of the box body 1. One end of the bracket 411 far from the outer wall of the box body 1 is fixedly installed with a motor 412. The output end of the motor 412 is fixedly installed with a reciprocating lead screw 413. A sleeve block 414 is sleeved on the outer wall of the reciprocating lead screw 413. A limiting rod 415 is arranged outside the reciprocating lead screw 413. The bottom of the sleeve block 414 is fixedly installed with a moving plate 416. A limiting block 417 is slidably arranged inside the moving plate 416. A spring 418 is fixedly installed on the outer wall of the limiting block 417. A brush plate 419 is fixedly installed on one side of the limiting block 417 far from the moving plate 416. A convex block 420 is fixedly installed on the inner wall of the box body 1. A limiting ring 421 is slidably arranged on the outer wall of the limiting rod 415.

[0032] In this embodiment, when anti-blocking treatment of rubber powder is required, the motor 412 is started, and the reciprocating lead screw 413 fixedly installed at its output end starts to rotate. Since the limiting ring 421 is slidably arranged on the outer wall of the limiting rod 415, under the limitation of the limiting rod 415, the rotating reciprocating lead screw 413 can drive the sleeve block 414 to reciprocate inside the box body 1. The sleeve block 414 drives the moving plate 416 to move accordingly, the moving plate 416 drives the limiting block 417 to move accordingly, and the limiting block 417 drives the spring 418 to move on the top surface of the filter plate 435, so as to evenly spread the rubber powder and prevent it from blocking in the filter plate 435. When the brush plate 419 brushes the filter plate 435, rubber powder is easily adhered to its inside. When the moving plate 416 drives the limiting block 417 and the brush plate 419 to move, the arc surface at the end of the brush plate 419 contacts and presses against the convex block 420 fixedly installed on the inner wall of the box body 1, causing the brush plate 419 to drive the limiting block 417 to slide under the moving plate 416. The limiting block 417 compresses the spring 418. When the brush plate 419 no longer contacts and presses against the convex block 420, at this time, under the elastic action of the spring 418, it pushes the limiting block 417 to reset, and reciprocally polarizes the brush plate 419 to shake off the rubber powder adhered to its inside, and cooperates with the push rod to perform anti-blocking treatment on the inside of the filter plate 435 (the box body 1, the crushing mechanism 2 and the push rod are prior art publicly disclosed in the comparative document, so their structures are not fully described in this case).

[0033] Among them, the end of the brush plate 419 is arranged in an arc shape, and the outer wall of the convex block 420 is arranged in an arc shape. Under its limitation, when the brush plate 419 contacts and presses against the convex block 420, the arc-shaped brush plate 419 and the convex block 420 can make the extrusion smoother.

[0034] Among them, the end of the limiting rod 415 is fixedly installed on the inner wall of the box body 1. The sleeve block 414 is movably sleeved on the reciprocating lead screw 413, and the limiting ring 421 is slidably arranged on the outer wall of the limiting rod 415. Under the limitation of the limiting rod 415, when the reciprocating lead screw 413 rotates, it can drive the sleeve block 414 to reciprocate.

[0035] Among them, there are eight convex blocks 420, which are evenly distributed inside the box body 1. Under the limitation of the convex blocks 420, when the brush plate 419 slides with it, the brush plate 419 can be extruded.

[0036] Among them, one end of the spring 418 is fixedly installed on the inner wall of the moving plate 416, and the end of the spring 418 far from the inner wall of the moving plate 416 is fixedly installed on the outer wall of the limiting block 417. Under the elastic action of the spring 418, when the brush plate 419 is not extruded, it pushes the brush plate 419 to reset.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, a preferred embodiment of a rubber powder production grinding machine capable of preventing blockage provided by the present utility model is as follows Figures 1 to 6As shown in the figure: The auxiliary component 43 includes a transmission mechanism 431 sleeved on the outer wall of the reciprocating screw rod 413. A rotating rod 432 is sleeved inside the transmission mechanism 431. An elliptical cylinder 433 is fixedly installed on the outer wall of the rotating rod 432. A slider 434 is fixedly installed on the inner wall of the box body 1. A filter plate 435 is slidably arranged on the outer wall of the slider 434.

[0039] In this embodiment, when the filter plate 435 filters the rubber powder, its interior is prone to clogging. At this time, when the reciprocating screw rod 413 rotates, it drives the rotating rod 432 to rotate through the transmission mechanism 431. The rotating rod 432 drives the elliptical cylinder 433 fixedly installed on its outer wall to rotate accordingly. The elliptical cylinder 433 presses against the bottom of the filter plate 435, causing the filter plate 435 to slide on the outer wall of the slider 434. When the elliptical cylinder 433 no longer presses against the bottom of the filter plate 435, under the action of gravity, the filter plate 435 slides downward on the outer wall of the slider 434, reciprocatingly vibrating the filter plate 435 to perform anti-clogging treatment. Since the bristles at the bottom of the brush plate 419 are made of soft material, under its restriction, the upward-moving filter plate 435 will not get stuck with the brush plate 419.

[0040] Among them, the number of sliders 434 is four, divided into two groups, symmetrically distributed with respect to the central axis inside the box body 1. Under the restriction of the sliders 434, it can ensure the stable sliding of the filter plate 435.

[0041] Among them, the elliptical cylinder 433 is elliptical in shape. The rotating rod 432 is in transmission connection with the reciprocating screw rod 413 through the transmission mechanism 431. Under the restriction of the transmission mechanism 431, when the reciprocating screw rod 413 rotates, it can drive the rotating rod 432 to rotate accordingly, so that the rotating rod 432 drives the elliptical cylinder 433 to push and press against the bottom of the filter plate 435.

[0042] Among them, holes are equidistantly arranged inside the filter plate 435. The outer wall of the filter plate 435 is slidably arranged with the inner wall of the box body 1.

[0043] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the various components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or selected and combined in multiple items. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
