Description

Technical Field

[0001] The invention relates to the technical field of strand pelletizing, in particular to a strand pelletizing machine with adjustable particle size. Background Art

[0002] Strand pelletizing refers to a granulation method for plastic processing. The molten plastic is extruded into strips through a die head by a screw extruder. After these strips are cooled and shaped in a cooling water tank, they are cut into pellets of a certain length by a strand pelletizer. However, the plastic pellets are squeezed by the cutter during the pelletizing process, making the shape of the pellets irregular, and the pellets are still easy to stick together after cutting.

[0003] The invention with publication number CN107471480A discloses a pelletizer, which sets an inclined cold water channel on the wall between the conical surface of the feed fixed tube and the inner cavity of the feed fixed tube, so that the cooling water entering the cold water tank is sprayed obliquely into the inner cavity of the feed fixed tube, thereby back-blowing the plastic strips to be cut, thereby achieving rapid cooling of the plastic strips to be cut, and at the same time greatly reducing the amount of water carried by the plastic strips to be cut after being output from the cooling device.

[0004] The invention with publication number CN111231154A discloses a water jet strand pelletizing device, wherein a water pipe is provided on a base frame, the water pipe corresponds to the end of a first water box that is inclined upward, and one end of the water pipe is closed, while the other end is connected to a water source. A first valve and a plurality of faucets are provided on the water pipe. The present invention has the effect of reducing the possibility of insufficient cooling of the strands.

[0005] However, the above-mentioned strip pelletizer for plastics still has the following problems during actual use: although the pelletizing of strip plastics is achieved through the conveying mechanism and the pelletizing tool, this type of pelletizing mechanism can only pelletize a single strip of plastic at a time, and the strip plastics that are not fully formed during the conveying process are prone to stick to the channel and then get blocked in the channel. At the same time, this type of pelletizing mechanism cannot be adjusted according to the length of the particle size, and thus cannot adapt to the needs of frequent replacement and adjustment.

[0006] Therefore, we proposed a particle size adjustable strand pelletizer to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a particle size adjustable strip pelletizer to solve the problem that the existing pelletizing of strip plastics is achieved by a conveying mechanism in conjunction with a pelletizing tool, but this type of pelletizing mechanism can only pelletize a single strip of plastic each time, and the strip plastic that is not fully formed during the conveying process is easy to stick to the channel and then get blocked in the channel.

[0014] Preferably, the inner end of the conveying branch pipe included in the conveying mechanism extends into the drawing rod slot hole opened inside the drawing rod column, and the inner end of the conveying branch pipe and the drawing rod slot hole are interconnected, and the outer end of the conveying branch pipe is interconnected with the circulation supply box on the top surface of the pelletizer body.

[0015] Preferably, the inner end of the conveying branch pipe included in the conveying mechanism is distributed in a "Y"-shaped structure, and the conveying branch pipe is used to convey the lubricating and cooling liquid inside the circulating supply box to the pull rod groove hole, the lubricating and cooling liquid is used to prevent the plastic pull rod from being blocked in the pull rod groove hole, and the circulating supply box included in the conveying mechanism is through-connected with the top end of the circulating through pipe.

[0016] Preferably, a pelletizing mechanism is provided at the front end of the pelletizer body, and the pelletizing mechanism includes a pelletizing bracket, and the pelletizing bracket is fixedly mounted on the outer wall of the driving shaft at the front end of the pull rod column, and a positioning pelletizing group and an adjustable pelletizing group are provided at equal angles at the outer end of the pull rod column.

[0017] Preferably, the outer ends of the positioning pelletizing group and the adjustable pelletizing group included in the pelletizing mechanism are fixedly provided with two pelletizing cutters, and the inner ends of the positioning pelletizing groups arranged at equal angles are fixedly connected to the outer ends of the pelletizing brackets, and the inner ends of the adjustable pelletizing groups arranged at equal angles are slidably provided on the inner ends of the pelletizing brackets.

[0018] Preferably, the pelletizing mechanism includes an elastic slide rod, and the rear end of the elastic slide rod is fixedly installed at an equal angle on the front side of the pelletizing bracket, and the outer end of the elastic slide rod is slidably connected to the inside of the adjusting tooth ring, and an adjusting gear is meshed at an equal angle at the rear of the adjusting tooth ring.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the particle size adjustable strand pelletizer conveys the strip plastic through the strand column, and the conveying branch pipe assists the strip plastic in lubrication and cooling, while the positioning pelletizing group and the adjustable pelletizing group at the outer end of the pelletizing bracket perform pelletizing operations to achieve cutting operations with different particle sizes and lengths, and stir the plastic particles after pelletizing to disperse and prevent adhesion. The specific contents are as follows:

[0021] 1. The rod slots of the rod column are used to transport columnar plastics. The circulating supply box transports lubricating coolant to the transport branch pipe, and then transports the lubricating coolant to the corresponding rod slots, thereby assisting the long plastic inside the rod slots to move and achieve cooling, avoiding blockage caused by the length problem that the plastic end cannot move.

[0022] The lubricating coolant flows out through the front end of the pulling rod column and enters the cooling container at the front end of the pelletizer body. Plastic debris and the like are filtered through the slots at the bottom of the cooling container so that the lubricating coolant can re-enter the circulation supply box through the circulating pipe connected through the connection, thereby realizing recycling.

[0023] 2. The driving shaft drives the pelletizer bracket, the positioning pelletizer group and the adjustable pelletizer group to rotate. The outer ends of the positioning pelletizer group and the adjustable pelletizer group have the same length. The inner ends of the two pelletizers correspond to the front ends of the pull rod slots. Then, the pelletizers at the outer ends of the positioning pelletizer group and the adjustable pelletizer group are used to cut the extended long strips of plastic. In this process, the lengths of the plastic particles cut are the same.

[0024] After the adjusting tooth ring is pressed, it meshes with the adjusting gear. The rotating adjusting tooth ring drives the adjusting gear and the adjusting sleeve to rotate, and the adjusting threaded rod threadedly connected to the adjusting sleeve is fixedly connected to the inner end of the adjustable pelletizing group, and then the adjustable pelletizing group is driven to move outward by the adjusting threaded rod, so that the adjustable pelletizing group changes the position of the corresponding pull rod slot through the pelletizing tool at its outer end.

[0025] When the adjustable pelletizer group drives the pelletizer tool at the outer end not to correspond to the pull rod slot, the plastic can only be cut by driving the positioning pelletizer group through the pelletizer bracket. At this time, the number of plastic particles cut at the same time is equal to half. When the adjustable pelletizer group only drives one adjustable pelletizer group to correspond to the pull rod slot, the particle size of the cut plastic particles is mixed, so as to realize quick and efficient adjustment to adapt to pelletizing work under different needs.

[0026] 3. The plastic particles enter the cooling container, and the rotating drive shaft drives the dispersion rods set at equal angles at the front end to rotate, so as to drive the falling plastic particles to be stirred and dispersed to avoid adhesion caused by continuous accumulation. At the same time, the lubricating cooling liquid that continues to remain allows the plastic particles to be immersed in it to accelerate the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0040] See also Figure 1-Figure 11 , the present invention provides the following technical solutions:

[0041] Embodiment 1: In order to solve the problems existing in the actual use of the existing strand pelletizer, this embodiment adopts the following technical scheme: a strand pelletizer with adjustable particle size, comprising a pelletizer body 1, and a circulation supply box 2 fixedly installed on the top surface of the pelletizer body 1, and a cooling container 3 is fixedly arranged at the front end of the pelletizer body 1; a strand mechanism is arranged inside the pelletizer body 1, and the strand mechanism includes a strand column 4, and the strand column 4 is fixedly installed at the inner center position of the pelletizer body 1; wherein, a conveying mechanism is arranged inside the pelletizer body 1, and the conveying mechanism includes a conveying branch pipe 5, and the conveying branch pipe 5 is fixedly installed at equal angles inside the pelletizer body 1 in a front-to-back symmetrical manner.

[0042] The inner end of the conveying branch pipe 5 included in the conveying mechanism extends to the strip drawing slot 7 opened inside the strip drawing column 4, and the inner end of the conveying branch pipe 5 and the strip drawing slot 7 are interconnected, and the outer end of the conveying branch pipe 5 is interconnected with the circulation supply box 2 on the top surface of the pelletizer body 1; the inner end of the conveying branch pipe 5 included in the conveying mechanism is distributed in a "Y" shape, and the conveying branch pipe 5 is used to convey the lubricating and cooling liquid inside the circulation supply box 2 to the strip drawing slot 7, the lubricating and cooling liquid is used to prevent the plastic strip from being blocked in the strip drawing slot 7, and the circulation supply box 2 included in the conveying mechanism is interconnected with the top end of the circulation pipe 9.

[0043] like Figure 4-Figure 6 As shown, the pelletizer body 1 realizes the plastic pulling operation through the internally fixed pulling rod column 4, and the pulling rod slot 7 opened in the pulling rod column 4 is used to transport the columnar plastic. At the same time, the circulation supply box 2 installed above the pelletizer body 1 transports the lubricating coolant to the delivery branch pipe 5 arranged at equal angles inside the pulling rod column 4, and the lubricating coolant is transported to the corresponding pulling rod slot 7 through the "Y"-shaped structure at the inner end of the delivery branch pipe 5, thereby assisting the long plastic inside the pulling rod slot 7 to move and achieve cooling, thereby avoiding the plastic end being unable to move and being blocked due to length problems.

[0044] Furthermore, the lubricating coolant inside the rod drawing slot 7 flows out through the front end of the rod drawing column 4 and enters the cooling container 3 at the front end of the pelletizer body 1, and the plastic debris and the like are filtered through the slots at the bottom of the cooling container 3, so that the lubricating coolant can re-enter the circulation supply box 2 through the through-connected circulation pipe 9, thereby realizing recycling.

[0045] Embodiment 2: In order to solve the problems existing in the actual use of the existing strip pelletizer, the present embodiment adopts the following technical scheme: the strip pulling mechanism includes a driving shaft 6, and the driving shaft 6 is rotatably arranged at the inner center position of the strip pulling column 4 through a bearing, and strip pulling slots 7 are opened at equal angles on both sides of the inner and outer sides of the strip pulling column 4 so that the plastic strips can be transported through the strip pulling slots 7; a pelletizing mechanism is arranged at the front end of the pelletizer body 1, and the pelletizing mechanism includes a pelletizing bracket 11, and the pelletizing bracket 11 is fixedly installed on the outer wall of the driving shaft 6 at the front end of the strip pulling column 4, and a positioning pelletizing group 12 and an adjustable pelletizing group 13 are arranged at equal angles at the outer end of the strip pulling column 4.

[0046] The pelletizing mechanism includes a positioning pelletizing group 12 and an adjustable pelletizing group 13, both of which are fixedly provided with two pelletizing cutters 14 at their outer ends, and the inner ends of the positioning pelletizing groups 12 set at equal angles are fixedly connected to the outer ends of the pelletizing brackets 11, and the inner ends of the adjustable pelletizing groups 13 set at equal angles are slidably provided on the inner ends of the pelletizing brackets 11; the pelletizing mechanism includes an elastic slide bar 19, and the rear end of the elastic slide bar 19 is fixedly installed at equal angles on the front side of the pelletizing bracket 11, and the outer end of the elastic slide bar 19 is slidably connected to the inside of the adjusting tooth ring 15, and the rear of the adjusting tooth ring 15 is meshed with an adjusting gear 16 at equal angles.

[0048] like Figure 3 , Fig. 9 As shown, the driving shaft 6 arranged at the center position inside the pulling rod column 4 is driven to rotate by the driving motor at the rear end, and at the same time, the driving shaft 6 drives the front end pelletizing bracket 11 and the positioning pelletizing group 12 and the adjustable pelletizing group 13 to rotate. In this process, the outer ends of the positioning pelletizing group 12 and the adjustable pelletizing group 13 have the same length, so that the inner ends of the two groups of pelletizing tools 14 correspond to the front ends of the pulling rod slots 7 opened inside the pulling rod column 4, and then the pelletizing tools 14 at the outer ends of the positioning pelletizing group 12 and the adjustable pelletizing group 13 are used to cut the extended long strips of plastic. In this process, the lengths of the plastic particles cut are the same.

[0049] Furthermore, when the length of the plastic pellet diameter needs to be changed, the adjusting tooth ring 15 is manually pressed toward the front of the pelletizing bracket 11, so that the adjusting tooth ring 15 engages with the adjusting gear 16 of equal angle, and the adjusting tooth ring 15 is rotated to drive the adjusting gear 16 and the distance adjusting sleeve 18 to rotate, and the distance adjusting threaded rod 17 threadedly connected to the distance adjusting sleeve 18 is fixedly connected to the inner end of the adjustable pelletizing group 13, and then the adjustable pelletizing group 13 is driven to move outward by the distance adjusting threaded rod 17, so that the adjustable pelletizing group 13 changes the position of the corresponding pull rod slot 7 through the pelletizing tool 14 at its outer end.
