Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, and in particular to a plastic crusher. Background Technology

[0002] Recycled plastics are often processed by plastic shredders to transform irregularly shaped materials into smaller plastic granules, facilitating transportation and subsequent processing. Typical plastic shredders use a pair of crushing rollers to tear the material entering between the rollers into granules of a size roughly equivalent to the distance between the rollers.

[0003] The plastic shredder described in announcement number CN217777473U includes a shredding chamber, a water inlet pipe fixedly installed on one side of the shredding chamber, a spray main pipe fixedly connected to one end of the water inlet pipe, a high-pressure nozzle installed at the bottom end of the spray main pipe, a water-permeable sliding channel fixedly connected to the inner side of the bottom end of the shredding chamber, a drying chamber fixedly connected to one side of the bottom end, and a drying fan fixedly installed inside the drying chamber; a fragment sliding channel fixedly connected to the inner side of the cutting chamber, one end of the fragment sliding channel being fixedly connected to a material extension ramp, and the other end being fixedly connected to a cutting discharge channel.

[0004] Based on the above technical features, the problem is that, in the existing technology, when plastic granules are wetted, due to the effects of friction, water adhesion, and surface tension, the sliding speed of the plastic granules along the permeable slide channel slows down, which easily leads to the accumulation of plastic granules on the permeable slide channel, thereby reducing the overall output efficiency of the machine, and even clogging the machine in severe cases.

[0005] Therefore, it is necessary to solve the above problems using a plastic shredder. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1: This utility model provides the following... Figures 1 to 3 The plastic crusher shown includes a cutting box 1, a discharge box 3, a crushing box 6, and a drying box 4.

[0028] A cutting mechanism is installed inside the cutting box 1, and a feeding component 5 is fixedly installed at the feed inlet of the cutting box 1.

[0029] The feeding assembly 5 is used to transport plastic waste and includes a conveyor belt.

The conveyor belt is mounted on the support frame. A first motor 23 is fixedly installed on the support frame, and the first motor 23 is connected to the conveyor rollers of the conveyor belt to provide power to the conveyor belt. The conveyor belt is prior art and will not be described in detail here.

[0030] The cutting mechanism is used to cut plastic waste and includes a cutting blade 101. The cutting blade 101 is rotatably mounted inside the cutting box 1. A second motor 22 is bolted to the cutting box 1, and the output shaft of the second motor 22 is connected to the cutting blade 101 for transmission. The cutting blade 101 is also existing technology and will not be described in detail here.

[0031] The discharge port of the cutting box 1 is fixedly connected to the inlet of the discharge box 3. A feeding plate 18 is provided at the discharge port of the cutting box 1. The feeding plate 18 is located below the cutting blade 101 and is inclined towards the inlet of the discharge box 3 for feeding.

[0032] The feeding plate 18 is a thin stainless steel plate and is fixedly connected to the cutting box 1. A third shaft 20 is rotatably mounted on the cutting box 1, and the third shaft 20 is arranged horizontally and located below the feeding plate 18. A hammer 19 is fixedly mounted radially on the third shaft 20. An elastic plate 1801 is fixedly connected to the bottom of the feeding plate 18. The hammer 19 impacts and engages with the elastic plate 1801 to vibrate the feeding plate 18, thereby accelerating the feeding process.

[0033] A torsion spring is fitted onto the third shaft 20, with one end of the torsion spring fixedly connected to the third shaft 20 and the other end fixedly connected to the cutting box 1. This is used for resetting the hammer 19.

[0034] A swing arm 13 is fixedly mounted radially on the third shaft 20, and the swing arm 13 is located outside the cutting box 1. The swing arm 13 is used to drive the third shaft 20 to rotate.

[0035] A discharge port is provided at the bottom of the discharge box 3, and the inlet of the crushing box 6 is fixedly connected to the discharge port of the discharge box 3.

[0036] A crushing roller and a water inlet pipe are rotatably installed inside the crushing box 6. The crushing roller is used to crush and cut plastic waste into pieces, and the water inlet pipe is used to spray water onto the crushing roller. The crushing roller and the water inlet pipe are driven by a linkage assembly.

[0037] The crushing rollers include a first crushing roller 1701 and a second crushing roller 1702. The first crushing roller 1701 and the second crushing roller 1702 are parallel to each other and located at the same height. The first crushing roller 1701 is coaxially and fixedly connected to a first shaft 1601, and the second crushing roller 1702 is coaxially and fixedly connected to a second shaft 1602. Both the first shaft 1601 and the second shaft 1602 are rotatably connected to the crushing box 6. A third motor 21 is bolted to the crushing box 6, and the output shaft of the third motor 21 is coaxially and fixedly connected to the first shaft 1601.

[0038] The first shaft 1601 is coaxially and fixedly connected to the first gear 801, and the second shaft 1602 is coaxially and fixedly connected to the second gear 802. The first gear 801 and the second gear 802 are meshed and both are located outside the crushing box 6. They are used to drive the first crushing roller 1701 and the second crushing roller 1702 to rotate.

[0039] The water inlet pipes include a first water inlet pipe 1101 and a second water inlet pipe 1102. Both the first water inlet pipe 1101 and the second water inlet pipe 1102 are rotatably connected to the crushing box 6.

[0040] Multiple high-pressure nozzles are fixedly connected to both the first water inlet pipe 1101 and the second water inlet pipe 1102. The multiple high-pressure nozzles are arranged linearly in a straight line along the axial direction of their respective water inlet pipes, and each high-pressure nozzle is also arranged radially along its respective water inlet pipe. This is used for spraying water.

[0041] The linkage assembly includes a first pulley 901, a second pulley 902, a third pulley 903, and a belt 10. The first pulley 901 is coaxially and fixedly connected to the first shaft 1601. The second pulley 902 is fixedly sleeved on the first water inlet pipe 1101, and the third pulley 903 is fixedly sleeved on the second water inlet pipe 1102. The first pulley 901, second pulley 902, and third pulley 903 are located outside the crushing chamber 6 and are driven through the belt 10. They are used to drive the first water inlet pipe 1101 and the second water inlet pipe 1102 to rotate synchronously.

[0042] The first water inlet pipe 1101 and the second water inlet pipe 1102 are both connected to an external water tank. This technology is existing technology and will not be described in detail here.

[0043] The rocker arm 13 is driven by a transmission component, including a cam 12, which is fixedly mounted on the second water inlet pipe 1102. The cam 12 has two protrusions symmetrically arranged about the center of its central axis, and these protrusions intermittently engage with the rocker arm 13. This drives the rocker arm 13 to revolve around the third shaft 20.

[0044] A permeable slide plate 15 is fixedly installed at the discharge port of the crushing chamber 6. The permeable slide plate 15 is located below the water inlet pipe and angled towards the feed inlet of the drying chamber 4. The feed inlet of the drying chamber 4 is fixedly connected to the discharge port of the crushing chamber 6. The permeable slide plate 15 has multiple water permeable holes arranged in a matrix. These holes are used to allow water mixed between the plastic particles to pass through.

[0045] The bottom of the pulverizing box 6 is provided with a drain outlet 7 to drain the water dripping from the permeable slide plate 15.

[0046] The discharge port of drying box 4 is connected to an external ton bag, which is existing technology and will not be described in detail here.

[0047] Working principle of Example 1: During production, plastic waste is conveyed to the cutting box 1 via the feeding assembly 5. The cutting blade 101 in the cutting box 1 cuts the plastic waste into plastic blocks. The plastic blocks fall onto the feeding plate 18 and slide along the feeding plate 18 into the discharge box 3.

[0048] Next, the plastic block falls from the discharge box 3 into the space between the first crushing roller 1701 and the second crushing roller 1702. The first crushing roller 1701 and the second crushing roller 1702 crush the plastic block. During this process, the output shaft of the third motor 21 drives the first shaft 1601 to rotate, and the first shaft 1601 drives the first crushing roller 1701 to rotate, while simultaneously driving the first gear 801 and the first pulley 901 to rotate.

[0049] When the first gear 801 rotates, it drives the second gear 802 to rotate. The second gear 802 drives the second shaft 1602 to rotate, and the second shaft 1602 drives the second crushing roller 1702 to rotate. The first crushing roller 1701 and the second crushing roller 1702 rotate relative to each other, thereby crushing the plastic block into plastic granules.

[0050] When the first pulley 901 rotates, it drives the second pulley 902 and the third pulley 903 to rotate synchronously via the belt 10. At this time, the second pulley 902 drives the first water inlet pipe 1101 to rotate, and the third pulley 903 drives the second water inlet pipe 1102 to rotate. The rotation of the first water inlet pipe 1101 and the second water inlet pipe 1102 drives the high-pressure nozzle to rotate.

[0051] The water sprayed from the high-pressure nozzle forms a water curtain with a certain impact force. When the high-pressure nozzle rotates to face the crushing roller, the water sprays to cool the crushing roller. When the high-pressure nozzle rotates to face the water-permeable slide plate 15, the water flow pushes the plastic particles on the water-permeable slide plate 15 toward the discharge port of the crushing box 6, thereby preventing the accumulation of plastic particles.

[0052] As the second water inlet pipe 1102 rotates, it drives the cam 12 to rotate. When the protrusion of the cam 12 contacts the rocker arm 13, it pushes the rocker arm 13 to rotate around the third shaft 20. The third shaft 20 drives the hammer 19 to rotate. During the rotation of the hammer 19, it strikes the elastic plate 1801, which causes the feeding plate 18 to vibrate. During the vibration of the feeding plate 18, the plastic block slides down faster.

[0053] After the protrusion of cam 12 rotates and disengages from rocker arm 13, under the action of torsion spring and elastic plate 1801, third shaft 20 reverses and drives hammer 19 to rotate away from elastic plate 1801 until it returns to its original position. Then, as cam 12 continues to rotate, hammer 19 intermittently strikes elastic plate 1801, causing feed plate 18 to vibrate intermittently.

[0054] Finally, the plastic granules slide into the drying chamber 4 through the permeable slide plate 15 for drying. The dried plastic granules fall into the ton bag from the discharge port of the drying chamber 4.

[0055] Example 2: This utility model provides the following... Figure 4 The plastic crusher shown in this embodiment differs from Embodiment 1 in that the linkage assembly includes a third gear 201 and a fourth gear 202. The third gear 201 is fixedly sleeved on the first water inlet pipe 1101, and the fourth gear 202 is fixedly sleeved on the second water inlet pipe 1102. The third gear 201 meshes with the first gear 801, and the fourth gear 202 meshes with the second gear 802.

[0056] The transmission component includes a lever 14, which is arranged radially along the second water inlet pipe 1102 and fixedly connected to the second water inlet pipe 1102. The lever 14 and the swing arm 13 intermittently engage in transmission.

[0057] Working principle of embodiment 2: The difference between the working principle of this embodiment and that of embodiment 1 is that when the first gear 801 rotates, it drives the third gear 201 to rotate; when the second gear 802 rotates, it drives the fourth gear 202 to rotate.

[0058] When the third gear 201 rotates, it drives the first water inlet pipe 1101 to rotate; when the fourth gear 202 rotates, it drives the second water inlet pipe 1102 to rotate.

[0059] When the second water inlet pipe 1102 rotates, it drives the actuating rod 14 to rotate around the second water inlet pipe 1102. When the actuating rod 14 rotates, it intermittently abuts against the swing rod 13 and pushes the swing rod 13 to rotate around the third shaft 20.

[0060] The other working processes are the same as in Example 1, and will not be described in detail here.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
