Description

Technical Field

[0001] The utility model relates to a waste plastic bottle brick processing method, in particular to a waste plastic bottle brick unpacking device. Background Art

[0002] In the waste recycling system, recyclers sort the collected waste according to regulations or standards, collect it, transport it, and process it, turning it into resource recycling. For plastic bottle recycling, they bundle and compress the bottles into bricks, then tie them together with ropes to create a brick structure, saving space and making them easier to transport.

[0003] When recycling plastic bottles, a forklift first transports the waste plastic bottle bricks to a conveyor belt. The bricks are then fed into an unpacking device, where rotating blades unpack and break them up. The broken-up plastic bottles are then further separated and transported via a conveyor belt. When this unpacking device unties the ropes holding the waste plastic bottle bricks, the high pressure within the bottles can easily cause the bricks to explode, impacting the safety of workers outside and causing them to fall outside the device, affecting work efficiency. For these reasons, it is necessary to design an unpacking device for waste plastic bottle bricks that can safely unpack and improve unpacking efficiency. Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to provide an unpacking device for waste plastic bottle bricks, so that the unpacking device can safely unpack the waste plastic bottle bricks and improve the efficiency of unpacking the waste plastic bottle bricks.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] The unpacking device for waste plastic bottle bricks includes a processing table, a conveyor belt arranged on the top of the processing table, a processing seat arranged on the top of the conveyor belt, and a breaking up assembly arranged inside the processing seat. Buffer rails are provided on both sides of the end of the processing seat close to the conveyor belt, and a winding door body that cooperates with the processing seat is slidably provided between the two buffer rails. A pressing assembly is provided on both sides of the processing seat. The telescopic end of the pressing assembly is located inside the processing seat and a buffer plate is provided. Multiple rows of pressure-dividing blades are provided on the buffer plate for decompression protection of waste plastic bottle bricks and the bottles inside them.

[0007] Preferably, a transmission motor connected to the winding door body is provided on the top of the buffer rail, and multiple tubular springs are provided on both sides of the interior of the buffer rail. Rollers are provided on the outside of the tubular springs, and the winding door body is located between the two rows of rollers.

[0008] Preferably, the pressing assembly includes an electric push rod passing through the processing seat, and the telescopic end of the electric push rod is provided with a buffer assembly connected to the buffer plate. When the electric push rod is telescoped, the buffer assembly is used to buffer the unpacking impact force exerted on the buffer plate.

[0009] Preferably, the buffer assembly includes a table-shaped spring, a small-diameter end of the table-shaped spring is provided with a groove-shaped pad connected to the electric push rod, and a large-diameter end of the table-shaped spring is provided with a rubber pad connected to the buffer plate.

[0010] Preferably, the buffer plate is two plates stacked by a plurality of pads, and the pads are made of damping material.

[0011] Preferably, an elastic cover is provided on the buffer plate between each column of pressure-dividing blades, the opening end of the elastic cover is arranged on the same side as the pressure-dividing blades, and the elastic cover is made of elastic material.

[0012] Preferably, the pressure dividing blade is provided with an arc portion on a side close to the winding door body.

[0013] Compared with the prior art, the unpacking device for waste plastic bottle bricks provided by the utility model can safely unpack waste plastic bottle bricks and improve the efficiency of unpacking waste plastic bottle bricks. Specifically, through the coordinated use of the buffer rails and the winding door on both sides of the input end of the processing seat, the isolation and protection of the exploded plastic bottles when the unpacking device unpacks the waste plastic bottle bricks is facilitated, thereby avoiding the scattering of plastic bottles that increases the processing time and cost of subsequent work and increases the unpacking safety of the device.

[0014] In addition, through the press-in component, buffer plate and pressure-dividing blade on the processing seat, the exploded plastic bottles can be cut and pressure-divided in real time, the impact force of the plastic bottles can be weakened, and the impact force of the waste plastic bottle bricks during decompression can be reduced. The press-in component drives the buffer plate to reciprocate and expand the waste plastic bottle bricks, which makes it convenient for the device to simultaneously pressure-divide and unpack the plastic bottles in the waste plastic bottle bricks. Combined with the use of the scattering component in the existing device, the waste plastic bottle bricks can be fully unpacked quickly, which is very beneficial to the recycling of waste plastic bottles.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] As attached Figure 1 and attached Figure 2As shown, the unpacking device for waste plastic bottle bricks provided by the embodiment of the present invention is used for unpacking waste plastic bottle bricks for explosion-proof treatment, and increases the unpacking safety and processing efficiency of the device. The existing unpacking device includes a processing table 1, a conveyor belt 11 arranged on the top of the processing table 1, a processing seat 12 arranged on the top of the conveyor belt 11, and a scattering component 13 arranged inside the processing seat 12. Buffer rails 21 are provided on both sides of the end of the processing seat 12 close to the conveyor belt 11. A winding door body 22 that cooperates with the processing seat 12 is slidably provided between the two buffer rails 21 for sealing the processing seat 12. Next, a pressing component 3 is provided on both sides of the processing seat 12. The telescopic end of the pressing component 3 is located inside the processing seat 12 and is provided with a buffer plate 4. A plurality of rows of pressure-dividing blades 5 are provided on the buffer plate 4 for decompression protection of the waste plastic bottle bricks and the bottles inside them. During processing, the waste plastic bottle bricks are transported to the conveyor belt 11 of the processing table 1 using a forklift. After the waste plastic bottle bricks are moved in, the motor is used to rotate the winding door 22 from the outside of the winding roller. The rotated winding door 22 slides toward the processing table 1 via the buffer rail 21, where it adheres to the surface of the processing table 1 and seals the processing seat 12. Through the transportation of the conveyor belt 11 and the coordination of the scattering component 13, the scattering component 13 first cuts the rope on that side of the waste plastic bottle brick, causing some plastic bottles to explode from the waste plastic bottle brick. The buffer plate 4 and the pressure-dividing blade 5 weaken the impact force of the exploded plastic bottles while cutting them, reducing the pressure in the bottles. The combined use of the pressing component 3 and the buffer plate 4 improves the unpacking efficiency of the unpacking device, prevents the scattering component 13 from getting stuck, and improves the processing efficiency of the device.

[0027] Applying the existing shutter door opening and closing technology, the reeling shaft of the reeling door body 22 is set between the two buffer rails 21, such as Figure 1 As shown, a transmission motor mounted on top of the buffer rail 21 transmits power to the reeling door 22, allowing the transmission motor to drive the reeling door to reel in or out, thereby sealing or opening the opening of the processing seat 12 and facilitating the unpacking device to seal the processed waste plastic bottle bricks. Furthermore, the structural connection between the reeling door 22 and the buffer rail 21 facilitates the use of multiple tubular springs 211 on both sides of the buffer rail 21 and rollers 212 mounted outside the tubular springs 211. Damping pads are provided at the connection between the tubular springs 211 and the buffer rail 21, providing shock absorption protection on both sides of the reeling door 22. When the reeling door 22 slides between the two rows of rollers 212, closing the processing seat 12, the impact force of the unpacking of the waste plastic bottle bricks is weakened by the deformation and friction of the multiple tubular springs 211 and the damping pads, reducing damage to the unpacking device and improving the effectiveness and safety of the unpacking device.

[0028] Among them, such as Figure 3As shown, in some embodiments, the press-in assembly 3 can use an electric push rod 31 that passes through the processing seat 12 as a driving structure. The telescopic end of the electric push rod 31 is provided with a buffer assembly 32 connected to the buffer plate 4. When the electric push rod 31 is extended or retracted, the buffer assembly 32 is used to buffer the unpacking impact force on the buffer plate 4. By applying the linear drive technology of the existing electric push rod 31, the extension or contraction of the electric push rod 31 can drive the buffer assembly 32 at the telescopic end of the electric push rod 31 to move, thereby adjusting the position of the buffer plate 4, shortening the gap between the buffer plate 4 and the waste plastic bottle brick, increasing the buffer connection end between the buffer plate 4 and the press-in assembly 3, and improving the connection effect between the press-in assembly 3 and the buffer plate 4.

[0029] It is worth noting that in order to better ensure the elastic connection between the electric push rod 31 and the buffer plate 4, as shown in FIG. Figure 4 As shown, the buffer assembly 32 can use a platform spring 322. The small-diameter end of the platform spring 322 is provided with a groove-shaped pad 321 connected to the electric push rod 31, and the large-diameter end of the platform spring 322 is provided with a rubber pad 323 connected to the buffer plate 4. When the unpacking device unpacks the waste plastic bottle brick, the impact force is directly transmitted to the buffer plate 4. The elastic deformation and friction between the large-diameter platform spring 322 and the rubber pad 323 can transmit less impact force to the groove-shaped pad 321. The friction between the small-diameter end of the platform spring 322 and the groove-shaped spring then increases the elastic buffer structure between the buffer plate 4 and the press-in spring. In addition, a damping pad can be provided between the gap between the platform spring 322 and the rubber pad 323 to increase the impact force attenuation effect of the platform spring 322, thereby achieving a shock absorption function. This improves the connection strength of the press-in assembly 3 to the buffer plate 4.

[0030] In some embodiments, in order to reduce the impact of decompression of waste plastic bricks and improve the protective effect of the buffer plate 4 on the device, such as Figure 3 As shown, the buffer plate 4 can be set as two plates with multiple pads 41 stacked together. The pads 41 can use damping materials. When the surface of the buffer plate 4 is squeezed, the two plates will simultaneously rub the pads 41 therebetween. By applying the damping material properties of the pads 41, the buffer plate 4 can weaken the impact force while transferring part of the force to the waste plastic bricks, thereby causing the relatively distributed vibration buffer plates 4 to squeeze the waste plastic bricks, thereby increasing the unpacking rate of the waste plastic bricks and improving the decompression effect of the waste plastic bricks.

[0031] In order to improve the unpacking rate of the device and increase the unpacking safety of the waste plastic bottle bricks, in some embodiments, as Figure 3 and 5As shown, an elastic shield 42 can be installed on the buffer plate 4 between each row of pressure-dividing blades 5. The elastic shield 42 is made of elastic material, with its open end located on the same side as the pressure-dividing blades 5. A flexible pressure-reducing structure is added to the buffer plate 4. The rigid and flexible buffer plate 4 further enhances the buffer plate 4's shock-absorbing effect on the impact force of the plastic bottles. When the unpacking device is operating, the exploded bottle portion passes through the buffer plate 4 and enters the elastic shield 42. The deformation and resetting of the elastic material of the elastic shield 42 reduces the impact force of the bottles in the waste plastic bottle brick. The rebounding bottle can then hit the waste plastic bottle brick, achieving labor-saving unpacking of the waste plastic bottle brick.

[0032] Furthermore, in some embodiments, the arc-shaped portion 51 is provided on the side of the pressure dividing blade 5 close to the winding door body 22, so as to facilitate the sliding of the waste plastic bottle brick into the processing seat 12 and avoid the waste plastic bottle brick being unpacked in advance. When the unpacking device is unpacking, the input waste plastic bottle brick will first be input to the side of the scattering component 13. The scattering component 13 cuts the rope on this side, thereby untying one side of the waste plastic bottle brick, and some bottles fall out of the waste plastic bottle brick. The buffer plate 4 and the pressure dividing blade 5 buffer and statically divide the bottles that fall out, and cut and divide the bottles that hit the pressure dividing blade 5. At this time, there are still some bottles that are pressed together. The electric push rod 31 on the pressing component 3 is used to move the position of the buffer plate 4, which can drive multiple rows of pressure dividing blades 5 to press toward the middle of the processing seat 12, so that the blades can cut the rope on the side of the waste plastic bottle and simultaneously perform translational cutting on the waste plastic bottle brick, thereby achieving the decompression processing of the bottles in the waste plastic bottle brick. The decompression blade can cut the bottles, preventing the explosion of waste plastic bottle bricks when they are directly unpacked, increasing the processing safety of the unpacking device and improving the unpacking completeness and speed of the device.

[0033] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
