Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of plastic crusher technology, and more specifically, to a dual-feed plastic crusher for preparing plastic handles. Background Technology

[0002] A dual-feed plastic crusher is a specialized device for crushing and reprocessing waste plastic products. It mainly consists of a feeding system, a crushing system, a discharging system, and an electrical control system. Dual-feed plastic crushers are widely used in waste plastic recycling and processing, effectively reprocessing waste plastic products, reducing resource waste, and minimizing environmental pollution.

[0003] In the existing technology, the crusher has two feed inlets, which can simultaneously crush different types or sizes of plastic raw materials. For example, one feed inlet can be used to feed larger pieces of plastic handle scraps, while the other feed inlet can be used to feed smaller plastic particles or debris, which improves the crushing efficiency and flexibility. However, when larger pieces of plastic handle scraps are fed into the feed inlet, they are often crushed by their own weight and the force of the crushing blades. This method has low crushing efficiency. At the same time, some users may manually press the plastic into the crushing blades in order to improve the crushing efficiency, which increases the risk of injury to the user. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a dual-feed plastic crusher for preparing plastic handles, which solves the technical problem that the crushing efficiency is too low and dangerous in the prior art when materials are crushed by their own gravity, the force of the crushing blades, and manual pressing.

[0005] According to one aspect, at least one embodiment of this disclosure provides a dual-feed plastic crusher for preparing plastic handles, a crusher body, the crusher body including a crushing frame, a crushing mechanism disposed below the crushing frame, the bottom end of the crushing frame communicating with the crushing mechanism, a first feed inlet disposed on the crushing frame, and further comprising:

[0006] A protective cover, the bottom end of which is fixedly connected to the top end of the crusher body, and one end of which is connected to the first feed inlet;

[0007] A feed frame is disposed on the top of the other end of the protective cover and communicates with the protective cover;

[0008] A transmission pusher is disposed inside the protective cover and on one side of the crushing frame, and is used to convey materials and push them into the crushing frame;

[0009] A pressing assembly is disposed within the crushing frame and is used to press the material downward.

[0010] Preferably, the transmission pusher includes:

[0011] Two sets of support seats, the bottom end of which is fixedly connected to the top end of the crusher body, and each set of support seats includes two support seats;

[0012] Two rotating shafts, each end of which is rotatably connected to one of the two support seats;

[0013] A first motor is mounted on a support base, and the output end of the first motor passes through the support base and is coaxially connected to the rotating shaft.

[0014] Two drive rollers are sleeved on the rotating shaft and fixedly connected to the rotating shaft coaxially;

[0015] A conveyor belt, which is tensioned and fitted onto two drive rollers;

[0016] Multiple pusher screens are provided, with one end of each screen fixedly connected to the conveyor belt. By starting the first motor, the output end of the first motor rotates, driving the rotating shaft to rotate. The rotating shaft drives the transmission roller to rotate, which in turn drives the conveyor belt to move along the conveyor belt.

[0017] Furthermore, the pressing assembly includes:

[0018] An electric cylinder is installed at the top of the crushing frame, and one end of the electric cylinder extends through the top of the crushing frame.

[0019] A connecting plate, one end of which is fixedly connected to the output end of the electric cylinder;

[0020] Multiple springs, one end of which is fixedly connected to the other end of the connecting plate;

[0021] An extrusion plate, one end of which is fixedly connected to the other end of the spring, is pushed downward by the electric cylinder to move the connecting plate downward, thereby causing the spring and the extrusion plate to move downward, thus extruding the material in the crushing frame downward.

[0022] In order to smoothly transfer materials onto the conveyor belt, there is an inclined angle between the feed frame and the protective cover, and one end of the feed frame is above the conveyor belt.

[0023] In order to allow the material on the conveyor belt to enter the crushing frame through the first feed inlet, the top of the conveyor belt is horizontally higher than the bottom of the first feed inlet.

[0024] Preferably, each of the pusher mesh plates is evenly distributed on the conveyor belt and is spaced at the same distance.

[0025] In order to allow the material to enter the crushing frame through the first feed inlet and to prevent the material from being blocked by the side wall of the crushing frame, the width of the conveyor belt is smaller than the width of the first feed inlet.

[0026] In order to ensure that the material is conveyed in the same direction and enters the crushing frame smoothly, a limiting plate is fixedly connected to the top of the support base, and one end of the limiting plate is in contact with the crushing frame.

[0027] In order to transfer the material through the first feed inlet and downward to the crushing mechanism, the inner bottom wall of the first feed inlet is inclined inward towards the crushing frame.

[0028] To prevent excessive waste from splashing into the protective cover through the first feed inlet during material crushing, an arc-shaped plate is fixedly connected to the outer wall of the crushing frame. The arc-shaped plate is positioned above the first feed inlet, with its bottom end higher than the top end of the pusher mesh plate.

[0029] The beneficial effects of the embodiments disclosed herein are as follows:

[0030] 1. In this disclosure, by setting a protective cover and a feeding frame with an inclined angle between the feeding frame and the protective cover, the material can be transferred smoothly and the material fragments can be prevented from splashing during crushing;

[0031] 2. In this disclosure, by providing a transmission pushing component, the first motor drives multiple pushing screens and materials to be transmitted on the conveyor belt. If the materials are stuck or piled up on the conveyor belt, the pushing screens can push the materials and transfer them into the crushing frame.

[0032] 3. In this disclosure, by setting up a pressing component, when the material is being crushed below the crushing frame, the electric cylinder is activated, and the electric cylinder drives the extrusion plate to move downward to press the material between the crushing mechanism and the extrusion plate. This applies pressure to the material being crushed, which can speed up the crushing of the material and improve the splashing of material fragments. This method promotes the crushing of the material, avoids manual assistance, and reduces the danger. Attached Figure Description

[0046] like Figures 1-5 As shown, it illustrates a dual-feed plastic crusher for preparing plastic handles according to an embodiment of the present disclosure. The crusher body 1 includes a crushing frame 2 and a crushing mechanism 18 disposed below the crushing frame 2. The crushing mechanism 18 is disposed inside the crusher body 1 and directly below the crushing frame 2. The bottom end of the crushing frame 2 is connected to the crushing mechanism 18. A first feed inlet 3 is provided on the crushing frame 2. In order to transfer the material through the first feed inlet 3 and downward to the crushing mechanism 18, the inner bottom wall of the first feed inlet 3 is inclined inward towards the crushing frame 2. In order to prevent excessive waste from splashing into the protective cover 4 through the first feed inlet 3 when the crushing mechanism 18 crushes the material, an arc plate 17 is fixedly connected to the outer wall of the crushing frame 2. The arc plate 17 is located above the first feed inlet 3, and the bottom end of the arc plate 17 is higher than the top end of the pusher mesh plate 11. The crusher also includes a protective cover 4, a feed frame 5, a transmission pusher component, and a pressing component.

[0047] like Figure 2 and Figure 3 As shown, the bottom end of the protective cover 4 is fixedly connected to the top end of the crusher body 1. One end of the protective cover 4 is connected to the first feed port 3. The feed frame 5 is set on the top of the other end of the protective cover 4 and is connected to the protective cover 4. In order to smoothly transfer the material to the conveyor belt 10, there is an inclined angle between the feed frame 5 and the protective cover 4, and one end of the feed frame 5 is above the conveyor belt 10.

[0048] like Figure 3 and Figure 4 As shown, the transmission pusher is located inside the protective cover 4 and on one side of the crushing frame 2. It is used to convey materials and push them into the crushing frame 2. The transmission pusher includes two sets of support seats 6, two rotating shafts 7, a first motor 8, two transmission rollers 9, a conveyor belt 10, and multiple pusher screens 11. The bottom end of the support seat 6 is fixedly connected to the top end of the crusher body 1. Each set of support seats 6 includes two support seats 6. In order to keep the material conveying direction consistent and smoothly enter the crushing frame 2, a limit plate 16 is fixedly connected to the top end of the support seat 6. One end of the shaft 6 is attached to the crushing frame 2. The limiting plate 16 guides the material. The two ends of the rotating shaft 7 are rotatably connected to two support seats 6 respectively. The first motor 8 is mounted on one support seat 6. The output end of the first motor 8 passes through the support seat 6 and is coaxially connected to the rotating shaft 7. The first motor 8 drives one rotating shaft 7 to rotate. The rotating shaft 7 drives the transmission roller 9 to rotate. The transmission roller 9 drives the conveyor belt 10 tensioned on the transmission roller 9 to rotate. In this way, the other transmission roller 9 and the rotating shaft 7 are driven to rotate. The transmission roller 9 is sleeved on the rotating shaft 7 and is connected to the rotating shaft 7. The conveyor belt 10 is coaxially fixedly connected and tensioned around two drive rollers 9. To allow material on the conveyor belt 10 to enter the crushing frame 2 through the first feed inlet 3, the top end of the conveyor belt 10 is horizontally higher than the bottom end of the first feed inlet 3. To ensure material enters the crushing frame 2 through the first feed inlet 3 and avoids obstruction by the side walls of the crushing frame 2, the width of the conveyor belt 10 is smaller than the width of the first feed inlet 3. One end of a pusher screen 11 is fixedly connected to the conveyor belt 10. Each pusher screen 11 is positioned on the conveyor belt 10... The materials are evenly distributed and spaced at the same distance. By starting the first motor 8, the output end of the first motor 8 rotates, which drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the transmission roller 9 to rotate, and the transmission roller 9 drives the conveyor belt 10 to drive, which in turn drives multiple pusher screens 11 to drive on the conveyor belt 10. The material is placed on the conveyor belt 10 through the feeding frame 5. Note that the material needs to be placed between two pusher screens 11. Driven by the first motor 8, the material is conveyed into the crushing frame 2 and transferred downward to the crushing mechanism 18 for crushing.

[0049] like Figure 5As shown, the pressing assembly is installed inside the crushing frame 2 to press the material downwards. The pressing assembly includes an electric cylinder 12, a connecting plate 13, multiple springs 14, and a pressing plate 15. The electric cylinder 12 is installed at the top of the crushing frame 2, with one end of the electric cylinder 12 penetrating through the top of the crushing frame 2 and extending thereafter. One end of the connecting plate 13 is fixedly connected to the output end of the electric cylinder 12. One end of each spring 14 is fixedly connected to the other end of the connecting plate 13. Multiple springs 14 are evenly distributed on the connecting plate 13. One end of the pressing plate 15 is fixedly connected to the other end of each spring 14. The outer wall of the pressing plate 15 is connected to the... The inner wall of the crushing frame 2 is attached. The electric cylinder 12 pushes the connecting plate 13 to move downward, which in turn moves the spring 14 and the pressing plate 15 downward. This compresses the material inside the crushing frame 2 downward. By activating the electric cylinder 12, the output end of the electric cylinder 12 pushes the connecting plate 13 to move downward, which in turn moves the spring 14 and the pressing plate 15 downward together. The material between the crushing mechanism 18 and the pressing plate 15 is squeezed by the pressing plate 15, and the spring 14 contracts. This applies pressure to the material being crushed, which can speed up the crushing of the material and improve the splashing of material fragments.

[0050] Working Principle: The dual-feed plastic crusher for making plastic handles is placed in a suitable location. When crushing larger plastic scraps such as plastic pipes used for making plastic handles, the material to be crushed is placed on the conveyor belt 10 through the feed frame 5, and positioned between two pusher screens 11. The first motor 8 is started, and its output rotates, driving the rotating shaft 7. The rotating shaft 7 drives the transmission roller 9, which in turn drives the conveyor belt 10, thus moving the multiple pusher screens 11 and the material along the conveyor belt. If material lingers or accumulates on the conveyor belt 10, the pusher plate 11 can push the material and transfer it into the crushing frame 2. Once the material is in the crushing frame 2, the electric cylinder 12 is activated. The output end of the electric cylinder 12 pushes the connecting plate 13 downward, causing the spring 14 and the extrusion plate 15 to move downward together. The material between the crushing mechanism 18 and the extrusion plate 15 is squeezed by the extrusion plate 15, and the spring 14 contracts. This applies pressure to the material being crushed, thus pushing the material to be crushed and avoiding manual assistance.
