[0002] Waste textiles can be melted by a melting device to produce glass fiber reinforced waste polyester-based PET engineering plastics, so that waste textiles can be recycled. However, there are many existing melting devices, among which a twin-screw extruder is a common melting device.

[0003] However, in the process of melting waste textiles, most of the existing twin-screw extruders place waste textiles at one end and melt them by rotating the screw. However, in the process of feeding, the waste textiles may be clumped due to the contact between the fabrics. The existing equipment cannot break them up and crush them, which will cause the waste textiles to accumulate at the feeding port. Manual pressing is required, which is inconvenient to operate. After the screw extruder melts the waste textiles, the material is discharged and formed through the die head at the other end. However, different shapes of materials will use different die heads. When disassembling and installing them, one hand is required to hold the die head and the other hand is required to rotate the bolt for installation. The installation is troublesome and inconvenient. Therefore, a melting device for deep groove screw processing is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a melting device for deep groove screw processing, including a fixed frame 1, the top of the outer wall of the fixed frame 1 is fixedly connected to a body 2, the body 2 is a twin-screw extruder well known in the prior art, a driving assembly is arranged on the right side thereof, and both the body 2 and the body 2 are prior art, a feeding mechanism 3 is arranged on the top of the outer wall of the body 2, and a die head 4 is detachably mounted on the left outer wall of the body 2 through a limiting assembly 6.

[0031] Reference Figure 1-Figure 2The feeding mechanism 3 includes a fixed cylinder 31, which is fixedly connected to the body 2 and fixedly connected to the top of the outer wall of the body 2. The rotating shaft 35 is rotatably connected to the inner wall of the top of the fixed cylinder 31. A semicircular block is provided at the top of the outer wall of the fixed cylinder 31, which is convenient for the waste textile to enter the interior of the fixed cylinder 31 from the guide plate 38. At the same time, it also plays a supporting effect on the rotating shaft 35 and the motor 34. The inner wall of the fixed cylinder 31 is elastically connected to the sliding sleeve 33 through a limiting spring 32. One end of the limiting spring 32 is fixedly connected to the surface of the outer side wall of the sliding sleeve 33, and the other end of the limiting spring 32 is fixedly connected to the top of the inner wall of the fixed cylinder 31. The function of the limiting spring 32 is to automatically reset the position of the sliding sleeve 33 after being squeezed and moved. The top of the outer wall of the fixed cylinder 31 is fixedly connected to the motor 34, and the output shaft of the motor 34 is fixedly connected to the rotating shaft 35. The rotating shaft 35 is rotated at a high speed by starting the motor 34. The top of the outer wall of the wall-breaking roller 36 contacts the inclined surface of the triangular block 37, and the contact between the two causes the triangular block 37 to be squeezed by the rotation of the wall-breaking roller 36 to drive the sliding sleeve 33 to move upward on the inner wall of the fixed cylinder 31. The bottom end of the outer wall of the sliding sleeve 33 is slidably connected to the inner wall of the top of the body 2, and the top of the outer wall of the fixed cylinder 31 is fixedly connected with a guide plate 38. The provision of the guide plate 38 facilitates the loading of waste textiles.

[0032] Reference Figure 3-Figure 4 The inner wall of the die head 4 is in contact with a bolt 5, the inner side wall of the die head 4 is in contact with the outer wall of the machine body 2, the bolt 5 is threadedly connected to the inner wall of the machine body 2, and the inner wall of the machine body 2 is provided with an internal thread that fits the bolt 5, so that the die head 4 as a whole can be connected and fixed to the machine body 2 by the bolt 5, and the inner side wall of the die head 4 is fixedly connected with two sets of guide blocks 7.

[0033] Reference Figure 3-Figure 4The limit assembly 6 includes a wedge block 62, which is elastically connected to the inner wall of the body 2 through a return spring 61, one end of the return spring 61 is fixedly connected to the outer wall of the wedge block 62, and the other end of the return spring 61 is fixedly connected to the inner wall of the body 2. The function of the return spring 61 is to automatically reset the wedge block 62 after the arc surface of the wedge block 62 is squeezed and moved. The outer wall of the wedge block 62 is fixedly connected to a moving rod 63, which penetrates and is slidably connected to the inner wall at the top of the body 2. The wedge block 62 The guide block 7 is slidably connected to the inner wall at the top of the body 2, and the wedge block 62 can be driven to move synchronously by grasping the moving rod 63. The guide block 7 is slidably connected to the inner wall of the body 2. The inner wall of the body 2 is provided with a sliding groove that matches the shape of the guide block 7, so that the guide block 7 can move upward on the inner wall of the body 2 when entering its inner wall from the bottom end of the body 2. The outer wall of the guide block 7 is provided with a card slot, and the bottom end of the outer wall of the wedge block 62 is card-engaged with the inner wall of the card slot, and the card slot between the two fixes the guide block 7 and the mold head 4 to the outer wall of the body 2.

[0034] Working principle: when melting waste textiles and feeding them, the motor 34 can be started first to make its output shaft drive the rotating shaft 35 to rotate, thereby driving the wall-breaking roller 36 to rotate at a high speed. At this time, the waste textiles that enter the fixed cylinder 31 along the guide plate 38 will be broken by the high-speed rotation of the wall-breaking roller 36. At the same time, during the rotation of the wall-breaking roller 36, the topmost wall-breaking roller 36 will contact the inclined surface of the triangular block 37, thereby squeezing the triangular block 37 to drive the sliding sleeve 33 to move upward on the inner wall of the fixed cylinder 31, and allowing the limit spring 32 to be elastically compressed until the two are no longer in contact. The sliding sleeve 33 will be elastically acted upon by the limit spring 32 to restore it to its initial position, thereby allowing the sliding sleeve 33 to reciprocate up and down, so that the waste textiles inside move up and down and are better broken by the wall-breaking roller 36.

[0035] At the same time, after the waste textile is melted, it will be discharged from the mold head 4 at the other end, so as to be formed according to the shape of the mold head 4. When the mold head 4 needs to be disassembled and replaced, the threaded connection of the bolt 5 to the machine body 2 can be rotated by a special tool. At this time, the two sets of moving rods 63 are pulled to drive the wedge block 62 to move outward, thereby canceling the clamping of the outer wall of the guide block 7. At this time, the mold head 4 can drive the two sets of guide blocks 7 to be taken out from the inner wall of the machine body 2. When installing, the two sets of guide blocks 7 are inserted into the corresponding empty grooves at the bottom end of the machine body 2, and the mold head 4 is pushed upward to drive the guide block 7 to move. The outer wall of the guide block 7 will squeeze the arc surface of the wedge block 62, squeeze it to move on the inner wall of the machine body 2, and let the reset spring 61 be elastically compressed until the guide block 7 is completely moved to the end. The wedge block 62 will be elastically acted on by the reset spring 61 to restore it to its initial position to clamp with the outer wall of the guide block 7, thereby fixing the position of the mold head 4 and the guide block 7, so as to facilitate the staff to rotate the bolt 5 for installation.
