Description

Technical Field

[0001] The utility model belongs to the field of foam rubber end cap processing equipment, in particular to a crusher for foam rubber capping processing. Background Art

[0002] The processing of foam rubber end caps includes the processing of foam rubber caps. Foam rubber caps can be used in various fields such as automobiles, pipelines, machinery, packaging, etc. due to different specifications and shapes. They have the advantages of high temperature resistance, anti-slip, elasticity, etc. The production process includes making cross-linked polyurethane foam particles, polyimide foam materials, fibers, lubricating materials, etc. into a certain fineness, and then heating them to a molten state and mixing them evenly, and then injection molding or extruding them into molded products. In order to meet the needs of energy conservation and emission reduction, the source of raw materials also includes recycled waste. Therefore, before melting, it involves crushing large pieces of raw materials such as waste through a crusher to increase the fineness of the raw materials to meet the feeding requirements and facilitate rapid mixing in subsequent processing.

[0003] Due to the low density and light weight of the foam rubber raw materials and even the certain elasticity of the waste materials, the use of a rotating shredder structure on a roller shaft is more conducive to the rapid crushing of the raw materials compared to hammer and jaw crushers. In order to further improve the crushing efficiency, the prior art also uses two sets of separately driven roller shafts, and a plurality of rotating blades are respectively arranged on the two sets of roller shafts. The rotating blades of one set of roller shafts are located between the adjacent rotating blades of the other set of roller shafts, so that after the material enters the crushing chamber of the crusher, it is crushed by the squeezing and shearing and grinding action of the roller shaft, and small particles of suitable size are discharged from the gap between the two roller shafts. However, since the material is automatically shredded by the rotating blades on the roller shaft after being put in, it is easy for the material to be unable to fully contact the rotating blades due to its shape, or large particles exceeding the gap take a long time to bounce and touch the top after the first crushing, and it takes a long time for it to continue to be crushed into small particles, resulting in a decrease in crushing efficiency; secondly, since the gap between the two sets of rotating blades is fixed, the shearing and grinding action is weak, which is not conducive to shredding and also causes a decrease in efficiency.

[0010] Furthermore, a plurality of fixed blades are arranged inside the shell, the plurality of fixed blades are divided into two groups and are respectively located outside the two roller shafts, and each fixed blade is located between adjacent rotating blades of the same roller shaft.

[0011] Furthermore, a V-shaped blade edge is provided on a side of the fixed blade facing the roller shaft.

[0012] Furthermore, the roller shaft includes a central shaft and an eccentric shaft, the central shaft is connected to a rotary drive, the rotary drive is used to drive the roller shaft to rotate around the axis of the central shaft, the eccentric shaft is eccentrically arranged with respect to the central shaft, and the rotating blade is concentrically arranged with respect to the eccentric shaft.

[0013] Furthermore, the rotary drive includes a motor, a pulley, a belt and a gear. There are two pulleys and they are respectively connected to the motor and any one of the center shafts. The belt cooperates with the two pulleys. There are two gears and they are respectively connected to the center shafts of the two rollers. The two gears mesh with each other.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) When the driving baffle is deflected around the hinge axis and located at one side of the inlet, the inlet can be opened for feeding; when the driving baffle is deflected around the hinge axis, the baffle posture changes. When it is close to the top of the two rollers, the baffle can be used to assist in squeezing the material and reduce the space where the material can bounce from the rollers, and then the material is crushed through the squeezing and shearing action of the rotating blade, solving the efficiency problem caused by the material not being able to fully contact the rotating blade or the long contact time, thereby improving the crushing efficiency of the foam capping process.

In the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In view of the problem that the crusher in the prior art is automatically shredded by the rotating blade after the material is put into the crusher, resulting in low efficiency in crushing the raw materials for foam capping, it is considered to use a top pressure structure to assist in squeezing the material to increase the contact area between the material and the rotating blade, reduce the time of material rebound, and improve efficiency, such as Figure 1 As shown, a preferred embodiment of the crusher for processing foamed rubber caps of the utility model is shown, the crusher for processing foamed rubber caps comprises a shell 1, an inlet 101 and an outlet 102 are respectively provided above and below the shell 1, two rotatable rollers 2 are provided in the shell 1, a plurality of rotating blades 3 are provided on the rollers 2, the rotating blade 3 of one roller 2 is located between adjacent rotating blades 3 of the other roller 2, the inlet 101 is located above the side of the two rollers 2, a baffle 4 is provided in the shell 1, a driving mechanism 7 and an articulated shaft 5 are provided between the baffle 4 and the shell 1, the driving mechanism 7 is used to drive the baffle 4 to reciprocate around the articulated shaft 5 between one side of the inlet 101 and above the two rollers 2.

[0031] The working principle of the above-mentioned crusher for foam capping processing includes:

[0032] like Figure 1As shown, the driving mechanism 7 drives the baffle 4 to deflect around the hinge shaft 5 and be located on one side of the inlet 101, so that the inlet 101 is opened, and the foam capping raw material, i.e., the material 10, can be put into the shell 1 from the inlet 101 and fall above the rotating blades 3 of the two rollers 2 under the restriction of the inner wall of the shell 1 and the baffle 4.

[0033] like Figure 2 As shown, the driving mechanism 7 drives the baffle 4 to deflect around the hinge shaft 5, so that the position of the baffle 4 changes, and it deflects from the side of the inlet 101 to the top near the two rollers 2, which can assist in squeezing the material 10 and make the material 10 contact with the rotating blade 3, thereby solving the efficiency problem caused by the material 10 not being able to fully contact the rotating blade 3 due to its shape. During the rotation of the rotating blade 3 with the roller 2, the rotating blade 3 is crushed by the squeezing and shearing action of the rotating blade 3, and the smaller-sized material 10 can fall from the gap between the rotating blade 3 of one roller 2 and the other roller 2, and then be discharged from the outlet 102. At the same time, because the baffle 4 reduces the space where the material 10 can bounce from the roller 2, the material 10 that needs to be further crushed can quickly return to the rotating blade 3 and be crushed due to the rebound of the baffle 4 even if it bounces, thereby solving the problem of decreased efficiency caused by the long top-touching time of the material 10, thereby improving the crushing efficiency.

[0034] Similarly, the baffle 4 can be driven by the driving mechanism 7. Figure 2 Reset to Figure 1 The state shown in the figure is then used for the next feeding and crushing process to meet the foam capping processing requirements.

[0035] Furthermore, the shell 1 is provided with a through hole 103, the back of the baffle 4 is provided with a driving arm 6 passing through the through hole 103, the hinge shaft 5 is located in the middle of the driving arm 6, the driving mechanism 7 includes a cylinder 701, the cylinder rod 702 of the cylinder 701 is hinged to the tail of the driving arm 6, and the cylinder 701 is hinged to the shell 1, then Figure 1 As shown, by contracting the cylinder rod 702, the driving arm 6 is pulled backward, so that when the driving arm 6 deflects around the hinge shaft 5, the baffle 4 is driven to deflect and be located on the side of the inlet 101, and at the same time, the cylinder 701 deflects correspondingly around the hinge position between the housing 1 and the driving arm 6; Figure 2 As shown, by extending the cylinder rod 702, the driving arm 6 is pushed forward, so that when the driving arm 6 deflects around the hinge shaft 5, the baffle 4 is driven to deflect in the opposite direction and is located above the two roller shafts 2. At the same time, the cylinder 701 deflects accordingly around the hinge position with the shell 1 and the driving arm 6 to achieve the switching of the baffle 4 posture. The cylinder 701 is located outside the shell 1 to avoid the problem of cylinder 701 being damaged by the material 10 due to being installed in the shell 1. After the baffle 4 is deflected, it can block the through hole 103 and avoid material leakage from the through hole 103, making the structure simpler, more compact and reasonably designed.

[0036] Furthermore, an articulated seat 104 is provided inside the shell 1, and the articulated seat 104 is connected to the driving arm 6 via an articulated shaft 5. The articulated seat 104 can be provided inside the shell 1 to install the articulated shaft 5, making the structure simpler and more compact.

[0037] like Figure 1-Figure 3 As shown, further, the rotating blade 3 is provided with a plurality of tooth tips 301, and the tooth tips 301 of adjacent rotating blades 3 on the same roller shaft 2 are staggered. For example, the rear rotating blade 3 on the same roller shaft 2 can be rotated by a certain angle compared with the front rotating blade 3, so that the tooth tips 301 of each rotating blade 3 are staggered. Then, by rotating the two roller shafts 2, the tooth tips 301 of different rotating blades 3 can be engaged with the material 10 to increase the contact reliability and further improve the processing efficiency.

[0038] Furthermore, a plurality of fixed blades 8 are provided inside the shell 1. The plurality of fixed blades 8 are divided into two groups and are respectively located on the outsides of the two rollers 2. Each fixed blade 8 is located between adjacent rotating blades 3 of the same roller 2. The material 10 can be crushed through the interaction between the rotating blade 3 and the fixed blade 8, thereby further improving the processing efficiency.

[0039] Furthermore, the fixed blade 8 is provided with a V-shaped blade edge 801 on the side facing the roller 2, which can increase the width and shearing effect of the upper part of the fixed blade 8, and small-sized materials 10 can be discharged from the gap between the V-shaped blade edge 801 of the fixed blade 8 and the roller 2.

[0040] Furthermore, the roller shaft 2 includes a central shaft 201 and an eccentric shaft 202, the central shaft 201 is connected to a rotation drive 9, the rotation drive 9 is used to drive the roller shaft 2 to rotate around the axis of the central shaft 201, the eccentric shaft 202 is eccentrically arranged with respect to the central shaft 201, and the rotating blade 3 is concentrically arranged with respect to the eccentric shaft 202.

[0041] like Figure 2 As shown, since the two rollers 2 rotate around their respective central axes 201 and the eccentric shaft 202 is eccentrically arranged, the gap between the rotating blade 3 of one roller 2 and the other roller 2 is relatively large; Figure 4 As shown, during the rotation process, since the rotating blade 3 is concentrically arranged with the eccentric shaft 202, at this time, the gap between the rotating blade 3 of one roller shaft 2 and the other roller shaft 2 is smaller; therefore, the eccentric structure changes the gap, and the shearing and grinding effect can be increased through the eccentric movement of the rotating blade 3, which is more conducive to shredding, and further solves the problem of decreased efficiency caused by the fixed gap between the two sets of rotating blades 3.

[0042] like Figure 3As shown, further, the rotation drive 9 includes a motor 901, a pulley 902, a belt 903 and a gear 904. There are two pulleys 902, which are respectively connected to the motor 901 and any one of the center shafts 201. The belt 903 cooperates with the two pulleys 902. There are two gears 904, which are respectively connected to the center shafts 201 of the two roller shafts 2. The two gears 904 are meshed with each other. The motor 901 of the rotation drive 9 can drive the connected pulley 902 to rotate, and the pulley 902 on a center shaft 201 can be driven to rotate under the transmission of the belt 903, so that the corresponding roller shaft 2 rotates around the axis of the center shaft 201, and then under the meshing transmission of the gear 904, the two roller shafts 2 rotate in opposite directions, thereby realizing driven rotation, making the structure simpler and more compact.

They are not intended to limit the protection scope of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the protection scope of the present invention.
