Description

Technical Field

[0001] The utility model relates to the technical field of garbage bag production equipment, in particular to an extrusion molding equipment for garbage bags. Background Art

[0002] The extrusion molding equipment for garbage bags is usually a plastic extruder. This equipment can heat and soften plastic particles and form a continuous plastic film by extrusion and extrusion. After cooling and cutting, these plastic films become individual garbage bags. The raw materials of garbage bags are plastic particles, and the sizes of plastic particles in different batches are different. At present, all plastic particles are directly poured into the silo of the extruder. When there are too many plastic particles in the silo, due to the influence of gravity, the particles flow quickly into the silo and squeeze each other together, forming a pile phenomenon. This pile-up will make it difficult for some particles to flow freely, and even form a bridge effect at the discharge port of the silo, hindering the normal flow and discharge of particles.

[0025] Embodiment 1:

[0026] like Figure 1-5 As shown, the utility model proposes an extrusion molding device for garbage bags, including a plastic extruder 1 and a silo 2 arranged on the plastic extruder 1, the interior of the silo 2 is provided with plastic particles, and also includes: a second receiving silo 3 rotatably installed on the top of the silo 2, the gap between the bottom of the second receiving silo 3 and the inner wall of the silo 2 is used to prevent the plastic particles from getting stuck, the top of the silo 2 is fixedly connected with a first receiving silo 21 tightly attached to the second receiving silo 3, the first receiving silo 21 is provided with a first penetration hole 22 for the plastic particles to pass through, the second receiving silo 3 is provided with a second penetration hole 31 corresponding to and overlapping with the first penetration hole 22, a vibration mechanism is provided in the silo 2 to quickly pass the plastic particles through the second penetration hole 31 and the first penetration hole 22 to avoid accumulation; an adjustment mechanism, rotatably arranged on the top of the silo 2, is used to control the speed at which plastic particles of different sizes pass through the second penetration hole 31 and the first penetration hole 22.

[0027] Furthermore, the vibration mechanism includes a plurality of support rods 35 fixedly connected to the top of the silo 2 and distributed in a circumferential array, wherein the tops of the plurality of support rods 35 are fixedly connected with a block 38, and another support rod 35 is connected with a handle 4, and the outer wall of the handle 4 is provided with a plurality of protrusions 41 distributed in a circumferential array, and the protrusions 41 improve the gripping force of the hand to avoid accidents or operational difficulties caused by hand slipping during use. The support rods 35 are all movably sleeved with a shock absorbing spring 36, and the function of the shock absorbing spring 36 is to make the vibration motor move a certain distance through the second receiving silo 3 when running, so that the plastic particles in the second receiving silo 3 vibrate more, thereby making the plastic particles pass through the second penetration hole 31 and the first penetration hole 22 faster. The top end of the shock-absorbing spring 36 is fixedly connected with a clamping ring 39 which is movably connected to the support rod 35. The top end of the second material receiving bin 3 is fixedly connected with a support ring 32. The support ring 32 is provided with a plurality of sliding holes 34 for the support rod 35 to movably pass through. The inner bottom wall of the second material receiving bin 3 is fixedly connected with a vibration motor cover 33, and a vibration motor is arranged inside the vibration motor cover 33.

[0028] Furthermore, the adjustment mechanism includes a plurality of locking holes 37 provided on the support ring 32 and located next to one of the sliding holes 34. The handle 4 is provided with a protrusion 44 for locking into the locking hole 37. A clamping plate 42 is fixedly connected to one end of the support rod 35 in the handle 4. The function of the clamping plate 42 is to prevent the top end of the support rod 35 from slipping out of the handle 4. A reset spring 43 movably sleeved with the support rod 35 is provided inside the handle 4. The function of the reset spring 43 is that when the handle 4 is not subjected to an upward pulling force, the handle 4 is subjected to the elastic thrust of the reset spring 43, which can drive the protrusion 44 to automatically lock into the corresponding locking hole 37.

[0029] In this embodiment, when it is necessary to use the extrusion molding equipment of the garbage bag, the size of the hole after the second perforation hole 31 and the first perforation hole 22 overlap is adjusted according to the size of the plastic particles this time, so as to avoid the hole after the second perforation hole 31 and the first perforation hole 22 overlap being too large, resulting in too fast flow rate of plastic particles and easy accumulation. It can also avoid that the hole after the second perforation hole 31 and the first perforation hole 22 overlap is too small, resulting in too slow flow rate of plastic particles into the plastic extruder 1. When adjusting the hole where the second perforation hole 31 and the first perforation hole 22 overlap just fit this batch of plastic particles, it is only necessary to move the handle 4 downward to drive the protrusion 44 out of the clamping hole 37 on the support ring 32. Then rotate the support ring 32 to drive the second receiving bin 3 to rotate, and the second receiving bin 3 drives the holes where the multiple second perforation holes 31 on it overlap with the first perforation hole 22 on the first receiving bin 21 to be adjusted to a suitable size. When the handle 4 is released again, the handle 4 will be subjected to the elastic thrust of the reset spring 43, so that the handle 4 drives the protrusion 44 to be stuck in one of the holes 37. At this time, the second receiving bin 3 during vibration can be prevented from driving the second penetration hole 31 thereon to move, and the size of the hole overlapped between the second penetration hole 31 and the first penetration hole 22 can be prevented from changing. Finally, all the plastic particles are poured into the second receiving bin 3 at the top of the bin 2, and the vibration motor in the vibration motor cover 33 is started. At this time, the plastic particles will flow into the plastic extruder 1 at a uniform speed through the hole where the second penetration hole 31 and the first penetration hole 22 overlap, which not only avoids the accumulation of plastic particles, but also prevents the flow rate from being too slow.
