Description

Technical Field

[0001] The present invention relates to the technical field of waste copper clad laminate recycling, and specifically relates to a waste copper clad laminate recycling device. Background Art

[0002] Copper clad laminate is the basic material of the electronics industry. With the rapid development of the electronics industry, the consumption of copper clad laminate is increasing continuously, and the generated waste copper clad laminate is also increasing day by day. The waste copper clad laminate contains various valuable components such as copper, resin and glass fiber. If not effectively recycled, it will not only cause waste of resources, but also cause serious pollution to the environment.

[0003] When processing waste materials in the existing technical system, a recycling device composed of a crushing device and a pyrolysis separation device is usually used. The crushing device generally consists of primary and secondary crushing mechanisms. Its main function is to fully crush the waste materials in the secondary stage, reduce their particle size, and prepare for the subsequent pyrolysis separation process. The pyrolysis separation device uses a high-temperature environment to cause the crushed waste materials to undergo pyrolysis reactions, separate different components therein, and realize the recycling of resources;

[0004] Moreover, in order to improve the automation degree of waste material processing, belt elevators are used to connect between each section. These belt elevators accurately convey the crushed materials to the pyrolysis separation device, ensuring the continuity of material transmission;

[0005] However, in combination with the actual situation, the discharging method of the existing belt elevator is relatively simple and direct. The waste materials usually fall directly in a free-fall manner. Due to the height difference between the discharging port of the belt elevator and the feeding port of the crusher or the pyrolysis separation device, the waste materials falling straight into the interior of the crusher or the pyrolysis separation device often form a large impact force. In the long run, it will seriously damage the internal components of the crusher and the pyrolysis separation device and affect the service life of the equipment. Summary of the Invention

[0006] To solve the above technical problems, a waste copper clad laminate recycling device is provided, which solves the problems described in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: a waste copper clad laminate recycling device, which mainly consists of a crushing device and a belt elevator. The crushing device is composed of a jaw crusher and a hammer crusher. The jaw crusher, the hammer crusher and the pyrolysis separation device are arranged at equal distances, and belt elevators are connected between the jaw crusher and the hammer crusher and between the hammer crusher and the pyrolysis separation device. It also includes an energy weakening mechanism for reducing the impact force when the waste materials fall.

[0008] The energy weakening mechanism is composed of a height difference adjusting part, an intermittent material control part, and a tipping and feeding part.

[0009] Preferably, the intermittent material control part includes a receiving cylinder with a cavity inside and arranged directly below the discharge end of the belt elevator, a receiving roller rotatably arranged in the inner cavity of the receiving cylinder, and a number of receiving grooves circumferentially formed on the roller body of the receiving roller. The top end of the receiving cylinder is fixedly communicated with a movable discharge hopper corresponding to the uppermost receiving groove, and the bottom end of the movable discharge hopper is provided with a discharge groove corresponding to the lowermost receiving groove.

[0010] Preferably, an installation groove is formed on one end face of the receiving roller, a servo motor fixedly connected to the inner wall on one side of the receiving cylinder is arranged in the installation groove, a power rod is fixed to the output shaft of the servo motor, and the end of the power rod is fixedly penetrated through the receiving roller along the axis and rotatably connected to the inner wall on the other side of the receiving cylinder.

[0011] Preferably, the height difference adjusting part includes a fixed discharge hopper slidably sleeved outside the movable discharge hopper and fixedly communicated with the discharge end of the belt elevator. A lifting sleeve rod is vertically slidably arranged on the side wall of the fixed discharge hopper, and the bottom end of the lifting sleeve rod is fixedly connected with the outer wall of the movable discharge hopper through a connecting plate.

[0012] Preferably, a driving motor is further installed on the side wall of the fixed discharge hopper, and a transmission screw rod fixedly connected to the output shaft of the driving motor is threadedly connected in the inner wall of the lifting sleeve rod.

[0013] Preferably, the tipping and feeding part includes a deflection sleeve covering the bottom of the receiving cylinder in a semi-cylindrical shape, a guide hopper fixedly communicated with the bottom end of the deflection sleeve, an intermittent energy supply part arranged on one side of the deflection sleeve, and an elastic reset part arranged on the other side of the deflection sleeve.

[0014] Preferably, the intermittent energy supply part includes a linkage cylinder fixedly penetrating through the inner wall of the deflection sleeve and rotatably connected to the receiving cylinder. A support is arranged inside the linkage cylinder. One end of the support is rotatably connected with a driven rod, an incomplete gear is tightly sleeved on the rod body of the driven rod, and a number of tooth blocks meshing with the incomplete gear are circumferentially fixed on the inner wall of the linkage cylinder.

[0015] Preferably, a linkage column is rotatably penetrated through the inner wall at the other end of the support. One end of the linkage column rotatably penetrates into the receiving cylinder and is fixedly connected with the end of the power rod. A linkage gear is tightly sleeved on the other end of the linkage column, and a driven gear meshing with the linkage gear is also tightly sleeved on the rod body of the driven rod.

[0016] Preferably, the elastic reset part includes a knob sleeve fixedly penetrating through the inner wall of the deflection sleeve and rotatably connected to the material receiving cylinder. A fixing rod fixedly connected to the side surface of the material receiving cylinder is arranged inside the knob sleeve.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) Through the arrangement of the intermittent material control part, when the waste material is output from the discharge end of the belt conveyor, the receiving roller rotates intermittently, so that several receiving grooves on its roller body sequentially move to the positions corresponding to the movable discharge hoppers, and then the waste material is received in turn, evenly dividing the waste material. When the receiving groove rotates with the receiving roller to the position corresponding to the discharge groove, the waste material can freely fall from the discharge groove. Thus, the intermittent material control part is used to reasonably adjust the actual output speed of the waste material, avoid the waste material being discharged too fast at one time, and prevent a large impact on subsequent equipment or treatment processes due to too fast discharge speed.

[0019] (2) Through the arrangement of the height difference adjustment part, when the driving motor is started, the output shaft of the driving motor drives the transmission screw rod to rotate, so that the lifting sleeve rod slides along the rod body of the transmission screw rod under the thread structure, and then the movable discharge hopper, the material receiving cylinder and the receiving roller as a whole are adjusted in lifting, trying to shorten the vertical distance between the waste material discharge place and the equipment feeding end, reduce the falling height of the waste material, and thus reduce the falling speed of the material.

[0020] (3) Through the arrangement of the dumping and feeding part, in which the intermittent energy supply part and the elastic reset part cooperate to make the deflection sleeve and the guide hopper deflect intermittently in positive and negative directions as a whole, so that the waste material output from the discharge groove is fed into the equipment in an inclined manner, further reducing the feeding speed of the waste material into the equipment and effectively reducing the impact force generated by free fall.

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0033] Referring to Figure 1 As shown, a waste copper clad laminate recycling device mainly consists of a crushing device and a belt elevator 4. The crushing device is composed of a jaw crusher 1 and a hammer crusher 2. The jaw crusher 1, the hammer crusher 2, and the pyrolysis separation device 3 are arranged at equal distances, and belt elevators 4 are connected between the jaw crusher 1 and the hammer crusher 2 and between the hammer crusher 2 and the pyrolysis separation device 3;

[0034] The inlet and outlet ends of one belt elevator 4 respectively correspond to the outlet end of the jaw crusher 1 and the inlet end of the hammer crusher 2;

[0035] The inlet and outlet ends of the other belt elevator 4 respectively correspond to the outlet end of the hammer crusher 2 and the inlet end of the pyrolysis separation device 3;

[0036] During use, the waste copper clad laminate to be processed is fed into the jaw crusher 1 for coarse crushing in advance, and then the belt elevator 4 is used to feed the coarsely crushed waste into the hammer crusher 2 for further crushing. The fully crushed material is fed into the pyrolysis separation device 3 by the belt elevator 4 again, and the shredded material is pyrolyzed under the set temperature and anaerobic environment;

[0037] The supplementary material receiving roller 11, the hammer crusher 2, the pyrolysis separation device 3, and the belt elevator 4 are all well-known technical equipment in the prior art, and the internal structure and operating principle thereof will not be elaborated in this case.

[0038] However, in combination with the actual situation, the existing discharging method of the belt elevator 4 is relatively simple and direct, and the waste is usually discharged directly by free fall. Since there is a height difference between the discharging port of the belt elevator 4 and the feeding port of the hammer crusher 2 or the belt elevator 4, the waste falling linearly directly enters the interior of the hammer crusher 2 or the belt elevator 4, often forming a large impact force. In the long run, it will seriously damage the internal components of the hammer crusher 2 and the belt elevator 4 and affect the service life of the equipment;

[0039] Therefore, with reference to Figures 2 - 9 As shown, it should be noted that an energy weakening mechanism for reducing the impact force when the waste falls is further included;

[0040] The energy weakening mechanism is composed of a height difference adjustment part, an intermittent material control part, and a dumping and feeding part;

[0041] Among them, the intermittent material control part includes a receiving cylinder 10 with a cavity inside and arranged directly below the discharging end of the belt elevator 4, a receiving roller 11 rotatably arranged in the inner cavity of the receiving cylinder 10, and a plurality of receiving grooves 12 circumferentially opened on the roller body of the receiving roller 11. The top end of the receiving cylinder 10 is fixedly communicated with a movable discharging hopper 6 corresponding to the uppermost receiving groove 12, and a discharging groove 13 corresponding to the lowermost receiving groove 12 is opened at the bottom end of the movable discharging hopper 6;

[0042] Through the setting of the intermittent material control part, when the waste is output from the discharging end of the belt elevator 4, the receiving roller 11 rotates intermittently, so that a plurality of receiving grooves 12 on its roller body sequentially move to the position corresponding to the movable discharging hopper 6, and then the waste is received in turn, and the waste is evenly divided. When the receiving groove 12 rotates with the receiving roller 11 to the position corresponding to the discharging groove 13, the waste can freely fall from the discharging groove 13. Thus, the intermittent material control part is used to reasonably adjust the actual output speed of the waste, avoid the waste from being discharged too fast at one time, and prevent a large impact on the subsequent equipment or treatment process due to too fast discharging speed.

[0043] Furthermore, with reference to Figure 5 and Figure 7As shown, it is worth noting that an installation groove 14 is formed on one end face of the material receiving roller 11. A servo motor 15 fixedly connected to the inner wall of one side of the material receiving cylinder 10 is arranged in the installation groove 14. A power rod 16 is fixed to the output shaft of the servo motor 15. The end of the power rod 16 fixedly penetrates through the material receiving roller 11 along the axis and is rotatably connected to the inner wall of the other side of the material receiving cylinder 10;

[0044] When the servo motor 15 is started, the output shaft of the servo motor 15 drives the power rod 16, so that the power rod 16 drives the material receiving roller 11 to rotate, providing a rotational force for the material receiving roller 11.

[0045] Furthermore, referring to Figures 3 - 6 As shown, it is worth noting that the height difference adjusting part includes a fixed discharge hopper 5 which is slidably sleeved outside the movable discharge hopper 6 and fixedly communicated with the discharge end of the belt elevator 4. A lifting sleeve rod 7 is vertically slidably arranged on the side wall of the fixed discharge hopper 5. The bottom end of the lifting sleeve rod 7 is fixedly connected to the outer wall of the movable discharge hopper 6 through a connecting plate;

[0046] A driving motor 9 is also installed on the side wall of the fixed discharge hopper 5. A transmission screw rod 8 fixedly connected to the output shaft of the driving motor 9 is threadedly connected in the inner wall of the lifting sleeve rod 7;

[0047] Through the setting of the height difference adjusting part, when the driving motor 9 is started, the output shaft of the driving motor 9 drives the transmission screw rod 8 to rotate, so that the lifting sleeve rod 7 slides along the rod body of the transmission screw rod 8 under the thread structure, and then the overall movable discharge hopper 6, material receiving cylinder 10 and material receiving roller 11 are adjusted in height, trying to shorten the vertical distance between the waste discharge place and the feeding end of the equipment, reducing the falling height of the waste, and thus reducing the falling speed of the material.

[0048] In addition, referring to Figures 2 - 4 As shown, it is worth noting that the tilting feeding part includes a deflection sleeve 17 covering the bottom of the material receiving cylinder 10 in a semi-cylindrical shape, a material guiding hopper 18 fixedly communicated with the bottom end of the deflection sleeve 17, an intermittent energy supply part arranged on one side of the deflection sleeve 17, and an elastic reset part arranged on the other side of the deflection sleeve 17;

[0049] Through the setting of the tilting feeding part, the intermittent energy supply part and the elastic reset part cooperate to make the deflection sleeve 17 and the material guiding hopper 18 tilt forward and backward intermittently as a whole, so that the waste discharged from the discharge chute 13 is fed into the equipment in an inclined manner, further reducing the feeding speed of the waste into the equipment and effectively reducing the impact force generated by free fall.

[0050] Furthermore, referring to Figure 2 、 Figure 8 And Figure 9As shown in the figure, it is worth noting that the intermittent energy supply part includes a linkage cylinder 19 fixedly inserted into the inner wall of the deflection sleeve 17 and rotatably connected to the material receiving cylinder 10. A support 20 fixedly connected to the side surface of the material receiving cylinder 10 is arranged inside the linkage cylinder 19. One end of the support 20 is rotatably connected to a driven rod 21. An incomplete gear 22 is tightly sleeved on the rod body of the driven rod 21. A number of tooth blocks 23 meshing with the incomplete gear 22 are fixedly arranged around the inner wall of the linkage cylinder 19.

[0051] A linkage column 24 rotatably penetrates through the inner wall of the other end of the support 20. One end of the linkage column 24 rotatably penetrates into the material receiving cylinder 10 and is fixedly connected to the end of the power rod 16. A linkage gear 25 is tightly sleeved on the other end of the linkage column 24. A driven gear meshing with the linkage gear 25 is also tightly sleeved on the rod body of the driven rod 21.

[0052] The elastic reset part includes a knob sleeve 26 fixedly inserted into the inner wall of the deflection sleeve 17 and rotatably connected to the material receiving cylinder 10. A fixing rod 27 fixedly connected to the side surface of the material receiving cylinder 10 is arranged inside the knob sleeve 26. A torsion spring 28 is sleeved on the rod body of the fixing rod 27. The two ends of the torsion spring 28 are respectively fixedly connected to the fixing rod 27 and the knob sleeve 26.

[0053] As shown above, when the servo motor 15 is started and the power rod 16 rotates, the linkage column 24 and the linkage gear 25 can rotate synchronously with the power rod 16 as a whole, so that the linkage gear 25 meshes with the driven gear, driving the driven rod 21 and the incomplete gear 22 as a whole. Furthermore, the incomplete gear 22 intermittently meshes with the tooth block 23, intermittently supplying rotation to the linkage cylinder 19 and the deflection sleeve 17 as a whole.

[0054] During the process that the incomplete gear 22 meshes with the tooth block 23 and causes the linkage cylinder 19 and the deflection sleeve 17 to deflect to one side, the knob sleeve 26 can rotate around the rod body of the fixing rod 27 synchronously and twist the torsion spring 28 to deform. In this way, by using the elastic force of the torsion spring 28, when the incomplete gear 22 no longer meshes with the tooth block 23, the knob sleeve 26 can quickly rotate back under the elastic force of the torsion spring 28, thereby realizing the intermittent deflection effect of the deflection sleeve 17 and the material guiding hopper 18.

[0055] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
