Description

Technical Field

[0001] This utility model belongs to the technical field of extrusion crushers, and in particular relates to an extrusion crusher. Background Technology

[0002] A crusher is a machine that uses mechanical devices to apply pressure to materials, causing the compressive stress on the materials to exceed the limit, thus crushing them into smaller pieces.

[0003] There are many types of compression crushers. For example, a double roller crusher is a crushing device that uses two sets of independently driven rollers to crush materials by generating squeezing and shearing forces through relative rotation. In order to adapt to various needs, a sliding table is set inside the double roller crusher to facilitate the adjustment of the position of the double rollers and their motors. This allows for the crushing of materials of different sizes according to requirements. However, when fixing the position of the sliding table, bolts or other structures are required for fixation. Although this fixing method provides good fixation and stability, it is relatively troublesome to disassemble and reassemble the bolts when making adjustments.

[0004] Therefore, how to provide a crushing and extrusion machine is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of an extrusion crusher according to an embodiment of the present invention, comprising:

[0034] Crushing frame 1;

[0035] Slide 2, slide 2 is symmetrically opened on both sides of crushing frame 1;

[0036] Groove 7, groove 7 is formed on the front side of crushing frame 1;

[0037] Slider 3 is movably disposed inside the slide groove 2 and the groove 7;

[0038] Electric bidirectional screw 4 is located on the front side of slide groove 2 and is movably connected to the left and right sliders 3.

[0039] The transmission wheel 6 is located inside the left and right sliders 3. The motor 13 is located at the outer end of the right slider 3 and is fixedly connected to the transmission wheel 6.

[0040] A rotating shaft 11 is fixedly installed on the inner side of the transmission wheel 6, and a pressing roller 12 is provided on its surface;

[0041] The tensioning structure is set on the surface of the slider 3 in the groove 7 and is connected to the transmission wheel 6 for transmission.

[0042] The reversing structure is located on the surface of the left transmission wheel 6 and is movably connected to the left rotating shaft 11.

[0043] In this embodiment of the invention, when in use, by symmetrically opening grooves 2 on the front side of the crushing frame 1 and setting sliders 3, and by setting electric bidirectional screws 4 in the grooves 2, the distance between the two sides of the extrusion rollers 12 can be adjusted indirectly and quickly. A tensioning structure is set on the front side of the crushing frame 1, so that the two sides of the transmission wheels 6 can run synchronously through a motor 13. A reversing structure is set on the left transmission wheel 6, so that the two sides of the extrusion rollers 12 rotate in opposite directions to crush the incoming material.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the outer sides of the left and right end slide grooves 2 are symmetrically provided with inlet and outlet grooves 22, and the inner sides of the left and right side slide grooves 2 are provided with through grooves 24. Baffles 23 are provided between and on the outer sides of the left and right side sliders 3. The outer baffles 23 are movably inserted into the inside of the inlet and outlet grooves 22, and the inner baffles 23 are movably inserted into the inside of the through grooves 24.

[0045] In this embodiment of the utility model, when the left and right sliders 3 move, they will drive the baffle 23 to move in the inlet / outlet groove 22 on the outside of the slide groove 2 and the through groove 24 on the inside.

[0046] By opening inlet and outlet slots 22 on both sides of the chute 2 and a through slot 24 inside the chute 2, and setting a baffle 23 on the surface of the slider 3 inside the chute 2, when the slider 3 moves, it will drive the baffle 23 to move in the inlet and outlet slots 22 and the through slot 24 to block the chute 2, thereby reducing the occurrence of dust and smoke generated during material crushing and affecting the surrounding environment.

[0047] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of this utility model, the reversing structure includes a rotating disk 15, a steering gear 16, a plug rod 17, and a toothed groove 19. The toothed groove 19 is formed on the surface of the left transmission wheel 6. The plug rod 17 passes through the middle of the transmission wheel 6 and is movably inserted into the middle of the corresponding slider 3. The rotating disk 15 is fixedly installed on the front side of the plug rod 17. The driven gear 18 is movably installed in the middle of the rotating disk 15. The plug block 14 is fixedly installed on the front side of the left rotating shaft 11 and is movably inserted into the middle of the driven gear 18. The steering gear 16 is movably installed on the left side of the rotating disk 15, and its inner and outer ends are respectively connected to the driven gear 18 and the toothed groove 19.

[0048] In this embodiment of the utility model, when the left transmission wheel 6 rotates, it will simultaneously drive the steering gear 16 at the right end of the rotating disk 15 on the front side of the insert rod 17 to rotate in place through the tooth groove 19 on its surface, thereby indirectly driving the driven gear 18 in the middle of the rotating disk 15 to rotate in the opposite direction, so that the left rotating shaft 11 and the right rotating shaft 11 rotate in opposite directions, thereby causing the extrusion rollers 12 on both sides to crush the material poured in through the feed port 20.

[0049] By setting a reversing structure, the two sides of the extrusion rollers 12 can rotate in opposite directions during operation, thereby crushing the material entering between the extrusion rollers 12.

[0050] like Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the tensioning structure includes a guide rod 8, a tensioning wheel 9, and a transmission belt 10. The tensioning wheel 9 is movably mounted on the surface of the slider 3 in the groove 7. The transmission belt 10 is disposed on the surface of the transmission wheel 6 and the tensioning wheel 9, so that the two rotating shafts 11 rotate synchronously. The guide rod 8 is arranged in an array inside the groove 7 and is movably inserted into the slider 3 in the groove 7. Springs 5 ​​are symmetrically arranged between the upper and lower sliders 3.

[0051] In this embodiment of the utility model, when the distance between the left and right sliders 3 increases, the transmission belt 10 and the tension wheel 9 will work together to make the upper and lower sliders 3 in the front groove 7 overcome the elasticity of the spring 5 and move closer to each other along the guide rod 8, thereby making the distance between the upper and lower tension wheels 9 closer.

[0052] By setting a tensioning structure, the transmission belt 10 used for transmission is always kept in a tensioned state when the left and right sliders 3 move, which facilitates the synchronous rotation of the two squeeze rollers 12.

[0053] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, both the insertion rod 17 and the insertion block 14 are square, and the middle part of the transmission wheel 6 is circular with a diameter greater than the width of the insertion rod 17.

[0054] In this embodiment of the utility model, when in use, both the insertion rod 17 and the insertion block 14 are set to be square, and the middle part of the transmission wheel 6 is set to be circular with a diameter greater than the width of the insertion rod 17, thereby facilitating the rotation of the transmission wheel 6 and preventing the insertion rod 17 from rotating.

[0055] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of this utility model, the cross-sectional size of the left and right sliders 3 is equal to the cross-sectional size of the groove 2, and the cross-sectional size of the upper and lower sliders 3 is equal to the cross-sectional size of the groove 7.

[0056] In this embodiment of the utility model, when in use, the cross-sectional size of the left and right sliders 3 is equal to the cross-sectional size of the groove 2, and the cross-sectional size of the upper and lower sliders 3 is equal to the cross-sectional size of the groove 7, thereby facilitating the movement of the sliders 3 within the corresponding grooves 2 and grooves 7.

[0057] like Figure 1 As shown, in a preferred embodiment of the present invention, a feed inlet 20 is fixedly installed on the top of the crushing frame 1, and a discharge pipe 21 is fixedly installed on the bottom of the crushing frame 1.

[0058] In this embodiment of the invention, when in use, an inlet 20 is fixedly installed on the top of the crushing frame 1, and a discharge pipe 21 is fixedly installed on the bottom of the crushing frame 1, thereby facilitating the entry and exit of materials.

[0059] The present invention provides a crushing machine in the above embodiments. When in use, the motor 13 on the outside of the slider 3 in the right slide groove 2 is started, which causes the transmission wheel 6 on the inside of the slider 3 in the right slide groove 2 to rotate, which in turn drives the corresponding rotating shaft 11 to rotate, which in turn drives the right extrusion roller 12 to rotate, and through the transmission belt 10, drives the tension wheel 9 and the left transmission wheel 6 to rotate synchronously.

[0060] When the left drive wheel 6 rotates, it will simultaneously drive the steering gear 16 at the right end of the rotating disk 15 on the front side of the insert rod 17 to rotate in place through the tooth groove 19 on its surface. This will indirectly drive the driven gear 18 in the middle of the rotating disk 15 to rotate in the opposite direction, thereby causing the left rotating shaft 11 to rotate in the opposite direction to the right rotating shaft 11. This will cause the extrusion rollers 12 on both sides to crush the material poured in through the feed port 20.

[0061] When it is necessary to adjust the distance between the left and right extrusion rollers 12, the electric bidirectional screw 4 is activated, which allows the distance between the left and right sliders 3 to be adjusted quickly.

[0062] At the same time, when the distance between the left and right sliders 3 increases, the upper and lower sliders 3 in the front groove 7 overcome the elasticity of the spring 5 and move closer to each other along the guide rod 8 through the cooperation of the transmission belt 10 and the tension wheel 9. This makes the distance between the upper and lower tension wheels 9 closer, so that the transmission belt 10 is always kept in a taut state, which facilitates the operation of the two side extrusion rollers 12.

[0063] At the same time, when the sliders 3 on the left and right sides move, they will drive the baffle 23 to move in the inlet and outlet groove 22 on the outside of the slide groove 2 and the through groove 24 on the inside, thereby preventing the dust generated by crushing from drifting out of the slide groove 2 and affecting the surrounding environment.

[0064] Subsequently, the crushed material will fall into the discharge pipe 21 and be discharged.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
