Description

Technical Field

[0001] This application relates to the technical field of granulators, in particular to a feeding device for a granulator. Background Art

[0002] During the production process of extruded boards, a large amount of waste is generated after operations such as cutting, reshaping, and punching the extruded boards. After crushing the waste, it is conveyed by a conveyor belt, lifted into the feed hopper of the granulator, and conveyed to the rear end by the auger of the granulator for processes such as extrusion, melting, forming, and cutting to form granular materials. The granular materials are stored in a storage box and can be used for the production of extruded boards or other purposes.

[0003] Currently, in existing granulators, the feeding speed of waste into the feed hopper is often slow, and in severe cases, the feed hopper may be blocked by waste. This not only causes the extrusion head module in the granulator to rotate idly but also affects the production effect of the granular materials. Therefore, a granulator that can maintain the feeding speed of the feed hopper is needed. Summary of the Utility Model

[0004] In order to maintain the feeding speed of the feed hopper, this application provides a feeding device for a granulator.

[0005] The feeding device for a granulator provided by this application adopts the following technical solutions:

[0006] A feeding device for a granulator includes a feed hopper, a feeding cylinder, an ejection structure, and an ejection rod. The feed hopper is communicated with the feeding cylinder; an installation frame is arranged in the feed hopper, and the ejection rod is vertically arranged on the installation frame; the ejection structure is used to drive the ejection rod to perform reciprocating motion in the vertical direction.

[0007] By adopting the above technical solutions, through the cooperation of the ejection structure and the ejection rod, the ejection rod can perform reciprocating motion in the vertical direction, enabling the waste to be more smoothly fed into the granulation box during the feeding process to maintain the feeding speed of the feed hopper, avoiding the pushing and blocking of waste in the feed hopper; thereby reducing the idle rotation of the extrusion head module in the granulation box and further maintaining the production effect of the granular materials.

[0008] Optionally, a plurality of anti-slip grooves are arranged on the outer wall of the ejection rod, and all the anti-slip grooves are arranged at intervals along the extension direction of the ejection rod.

[0009] By adopting the above technical solutions, by setting the anti-slip grooves, the surface area of the outer wall of the ejection rod can be increased, thereby increasing the friction between the ejection rod and the waste, which helps the ejection rod to more effectively bring the waste into the granulation box during the ejection process, thus maintaining the feeding speed of the feed hopper.

[0010] Optionally, the mounting bracket is provided with an ejection groove, and the ejection rod is movably installed in the ejection groove; the ejection structure includes a first motor, a rotating shaft, an eccentric wheel and a connecting member. The mounting bracket is provided with a driving groove communicating with the ejection groove. The rotating shaft is rotatably installed in the driving groove, and the first motor is installed on the outer wall of the feed hopper for driving the rotating shaft to rotate; the eccentric wheel is fixed to the rotating shaft, and the connecting member is used to drive the ejection rod to be normally in contact with the outer peripheral wall of the eccentric wheel.

[0011] By adopting the above technical solution, when the ejection structure is working, the first motor drives the rotating shaft to rotate in the driving groove, and the rotating shaft drives the eccentric wheel to rotate; due to the characteristics of the eccentric wheel, its outer peripheral wall will generate periodic displacement during the rotation process; and the connecting member can drive the ejection rod to be normally in contact with the outer peripheral wall of the eccentric wheel, so that the ejection rod is subjected to a thrust away from the bottom of the feed hopper, thereby bringing the waste into the granulation box.

[0012] And by arranging the first motor on the outer wall of the feed hopper, it is convenient for the staff to repair the first motor and maintain the service life of the ejection structure.

[0013] Optionally, the connecting member includes a slider, and the slider is fixed to one end of the ejection rod close to the mounting bracket; a ring groove for the slider to slide is formed on the outer peripheral wall of the eccentric wheel.

[0014] By adopting the above technical solution, through the sliding connection between the slider and the ring groove, the ejection rod can be normally connected to the outer wall of the eccentric wheel; so that the eccentric wheel can push the ejection rod during rotation.

[0015] Optionally, the connecting member includes a spring and a movable block fixed to the outer peripheral wall of the ejection rod. An activity groove is formed on the inner wall of the ejection groove, and the movable block is movably installed in the activity groove; both ends of the spring are fixed to the movable block and the inner wall of the activity groove respectively, and the elastic force of the spring is used to drive the ejection rod to move toward one side of the mounting bracket.

[0016] By adopting the above technical solution, the elastic force of the spring drives the ejection rod to move toward the side close to the mounting bracket, so that the ejection rod is normally in contact with the outer peripheral wall of the eccentric wheel, so that the eccentric wheel can push the ejection rod during rotation.

[0017] Optionally, a rubber sleeve is sleeved on the outer wall of the ejection rod, and both ends of the rubber sleeve are fixed to the ejection rod and the mounting bracket respectively.

[0018] By adopting the above technical solution, the rubber sleeve can cover the gap between the ejection rod and the ejection groove, reducing the situation that the waste is brought between the ejection rod and the inner wall of the ejection groove when the ejection rod makes a reciprocating motion, and maintaining the smoothness of the movement of the ejection rod.

[0019] Optionally, a tip is provided at one end of the ejector rod away from the mounting bracket.

[0020] By adopting the above technical solution, by providing the tip, the resistance of the ejector rod moving in the waste can be reduced, thereby reducing the possibility of damage to the ejector rod.

[0021] Optionally, both ends of the mounting bracket are connected to the inner wall of the feed hopper by bolts.

[0022] By adopting the above technical solution, by providing the bolts, the mounting bracket and the feed hopper can be detachably connected, so as to facilitate the maintenance of the ejecting structure by the staff, thereby improving the service life of the ejecting structure.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the ejecting structure and the ejector rod, the ejector rod can make a reciprocating motion in the vertical direction, which can make the waste be more smoothly fed into the granulating box during the feeding process, maintain the feeding speed of the feed hopper, and avoid the pushing and blocking of the waste in the feed hopper; thus reducing the idling of the extrusion head module in the granulating box, and further maintaining the production effect of the granular material;

[0025] 2. By providing the anti-slip grooves, the friction between the ejector rod and the waste can be increased, so as to facilitate the ejector rod to more effectively bring the waste into the granulating box during the ejection process, thereby maintaining the feeding speed of the feed hopper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will further elaborate on this application with reference to the attached drawings. Figures 1-4 A further detailed description of this application will be given below.

[0032] Embodiment 1:

[0033] The embodiment of this application discloses a feeding device for a granulator.

[0034] Referring to Figure 1 and Figure 2 , a feeding device for a granulator includes a feed hopper 1, a material conveying cylinder 2, a top rod, and a top structure. The feed hopper 1 is communicated with a material conveying hopper; a screw 3 is rotatably installed in the material conveying hopper, and the material conveying hopper is provided with a second motor 31 for driving the screw 3 to rotate; when waste materials enter the material conveying hopper through the feed hopper 1, the screw 3 can convey the waste materials to the rear end of the granulator for processing to form granular materials.

[0035] Referring to Figure 3 , the feed hopper 1 is provided with a mounting frame 4. Both ends of the mounting frame 4 are provided with fixing plates 41, and the fixing plates 41 are used to abut against the inner wall of the feed hopper 1; the fixing plates 41 are provided with threaded holes 42, and threaded grooves 11 are formed in the inner wall of the feed hopper 1. Bolts 43 are inserted through the threaded holes 42 and the threaded grooves 11. The mounting frame 4 is connected to the feed hopper 1 through the bolts 43, so that it is convenient for workers to take out the mounting frame 4 for maintenance outside.

[0036] Referring to Figure 3 , a jacking groove 44 is formed on one side of the mounting frame 4 away from the feed hopper 1. A jacking rod 5 is slidably installed in the jacking groove 44, and the mounting frame 4 is provided with a jacking structure 6 for driving the jacking rod 5 to perform reciprocating motion in the vertical direction; a tip is provided on one side of the jacking rod 5 away from the mounting frame 4. The provision of the tip can reduce the resistance of the jacking rod 5 moving in the waste materials, thereby reducing the possibility of damage to the jacking rod 5 during the movement process and improving the service life of the jacking rod 5.

[0037] A plurality of anti-slip grooves 51 are provided on the outer wall of the jacking rod 5, and all the anti-slip grooves 51 are arranged at intervals along the extension direction of the jacking rod 5; the anti-slip grooves 51 can increase the friction between the jacking rod 5 and the waste materials, which helps the jacking rod 5 to more effectively bring the waste materials into the granulation box during the jacking process.

[0038] A rubber sleeve 52 is sleeved on the outer wall of the jacking rod 5, and both ends of the rubber sleeve 52 are adhesively provided with the outer wall of the jacking rod 5 and the top wall of the mounting frame 4 respectively. The rubber sleeve 52 can hide the gap between the jacking groove 44 and the jacking rod 5, reduce the situation that the waste materials are brought into the interior of the jacking groove 44 during the reciprocating movement of the jacking rod 5, thereby maintaining the smoothness of the movement of the jacking rod 5 on the mounting frame 4.

[0039] The ejection structure 6 includes a first motor 61, a rotating shaft 62, an eccentric wheel 63 and a connecting member 64. A driving groove 46 communicating with the ejection groove 44 is formed inside the mounting frame 4, and the extending direction of the driving groove 46 is perpendicular to the extending direction of the ejection rod 5. Both ends of the rotating shaft 62 are rotatably mounted on opposite side walls of the driving groove 46, and one end of the rotating shaft 62 sequentially passes through the mounting frame 4 and the feed hopper 1 and is exposed to the outside. A connecting frame is provided on the outer wall of the feed hopper 1, and the first motor 61 is fixed to the connecting frame and fixed to the rotating shaft 62. Starting the first motor 61 can cause the rotating shaft 62 to rotate in the driving groove 46.

[0040] An installation hole 65 is formed at the center of the eccentric wheel 63, and the installation hole 65 of the eccentric wheel 63 is sleeved on the rotating shaft 62 and fixed to the outer wall of the rotating shaft 62. In this embodiment, the connecting member 64 includes a movable block 642 and a spring 641. The movable block 642 is fixed to the outer wall of the ejection rod 5, and a movable groove 45 for the movable block 642 to slide is formed on the inner wall of the ejection groove 44. Both ends of the spring 641 are fixed to the movable block 642 and the inner wall of the movable groove 45 respectively. The elastic force of the spring 641 can drive the ejection rod 5 connected to the movable block 642 to move towards one side of the mounting frame 4, that is, the elastic force of the spring 641 can drive the ejection rod 5 to be in contact with the outer peripheral wall of the eccentric wheel 63 under normal conditions.

[0041] The implementation principle of Embodiment 1 of this application is as follows:

[0042] When the waste material is introduced into the feed hopper 1, the machine drives the rotating shaft 62 to rotate in the driving groove 46, and the rotating shaft 62 drives the eccentric wheel 63 to rotate. Due to the characteristics of the eccentric wheel 63, its outer peripheral wall will generate periodic displacements during the rotation process. Since the elastic force of the spring 641 can make the ejection rod 5 contact with the outer peripheral wall of the eccentric wheel 63 under normal conditions, the ejection rod 5 is subjected to a thrust away from the bottom of the feed hopper 1. Thus, the waste material can be more smoothly fed into the granulation box during the feeding process, maintaining the feeding speed of the feed hopper 1, avoiding the pushing and blocking of the waste material in the feed hopper 1. Thus, the idling of the extrusion head module in the granulation box is reduced, and the production effect of granular materials is maintained.

[0043] Embodiment 2:

[0044] The embodiment of this application discloses a feeding device of a granulator.

[0045] Referring to Figure 4 , the difference between Embodiment 2 and Embodiment 1 of this application is that: the connecting member 64 includes a slider 643, a ring groove 66 is formed on the outer peripheral wall of the eccentric wheel 63, the slider 643 is fixed to one end of the ejection rod 5 and is slidably mounted in the ring groove 66, and a lubricating layer is coated on the inner wall of the ring groove 66, which can improve the smoothness of the slider 643 sliding in the ring groove 66.

[0046] In other embodiments, ball bearings that can rotate freely are provided on the outer wall of the slider 643, and the ball bearings are used to abut against the inner wall of the annular groove 66, further improving the smoothness of the sliding of the slider 643 in the annular groove 66.

[0047] The implementation principle of Embodiment 2 of this application is as follows:

[0048] By providing the slider 643, the ejector rod 5 can be rotatably connected to the outer peripheral wall of the eccentric wheel 63, so that the eccentric wheel 63 drives the ejector rod 5 to move periodically during rotation, so as to send the waste into the granulation box under the action of the ejector rod 5 and maintain the feeding speed in the feed hopper 1.

[0049] The above are the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
