Description
Technical Field
[0001] The invention relates to the technical field of plastic rod extrusion shaping, and in particular to plastic rod extrusion shaping equipment with an anti-adhesion structure. Background Art
[0002] Plastic rods are a common plastic product. In the process of plastic rod molding, extrusion molding is one of the main methods for producing plastic rods. The plastic raw materials are melted and plasticized by an extruder, and then continuously extruded by a screw. The rods are made into rods of the desired shape through a mold shape. Among the many plastic rods, there is a special one, namely, plastic hollow rods, which have a hollow structure inside. In some cases, the hollow structure inside can be used to provide better bending strength and rigidity, and the hollow part can be used to convey or protect wires.
[0003] The manufacturing process of the above-mentioned hollow plastic rods is roughly the same as that of common plastic rods except for the mold, but it should be noted that the formed hollow plastic rods are transported to the cooling cavity during the continuous extrusion process for cooling and shaping. However, due to the continuous extrusion operation, the inner and outer walls of the hollow plastic rods are prone to inconsistent cooling effects during the non-stop forward movement. When the cut hollow plastic rods fall freely to the material storage box due to gravity, adjacent rods are prone to pit defects after collision due to the difference in cooling effects of the inner and outer walls. In addition, as the rods are further cooled at room temperature, the problem of mutual adhesion also appears, which has an adverse effect on the surface quality and subsequent processing of the hollow plastic rods.

[0027] refer to Figure 1-Figure 9The formed hollow plastic rod is transported to the cooling chamber 4 during the continuous extrusion process for cooling and shaping. However, due to the continuous extrusion operation, the inner and outer walls of the hollow plastic rod are prone to inconsistent cooling effects during the non-stop forward movement. When the cut hollow plastic rod falls freely to the material storage box under the action of gravity, adjacent rods are prone to pit defects after collision due to the difference in cooling effects of the inner and outer walls. In addition, as the rods are further cooled at room temperature, the problem of mutual adhesion also appears, which has an adverse effect on the surface quality and subsequent processing of the plastic rods. In order to overcome the above-mentioned defects, the present application designs a plastic rod extrusion molding equipment with an anti-adhesion structure, which can not only effectively avoid bumps and pits caused by uneven internal and external cooling effects of the plastic after molding, but also avoid the adhesion problem of two adjacent rods after cooling to room temperature.
[0028] Cutting and separation of plastic bars: Initially, the external stepper motor is started to drive the partition chamber 5 to rotate intermittently. When the partition chamber 5 rotates to above the inverted T-shaped boss 71, the support plate 611 preferentially contacts the matching piece 711 provided on the inverted T-shaped boss 71. At this time, the support plate 611 is gradually pushed and compressed by the matching piece 711, thereby retracting into the interior of the partition chamber 5.
[0029] When the support plate 611 is in the compression process, the three arc-shaped support pieces 614 arranged thereon move upward synchronously until they move to the center position of the partition chamber 5. At this time, the arc-shaped expansion pieces 615 arranged on the three arc-shaped support pieces 614 pop out quickly due to lack of support.
[0030] While the partition bin 5 is rotating, the plastic rod is gradually transported by the external conveying equipment to the interior of the partition bin 5 and passes through the annular cutting equipment 54, so that the hollow part of the plastic rod is sleeved on the outer wall of the three arc-shaped support pieces 614, and the rotation of the partition bin 5 continues. When the supporting plate 611 rotates and gradually becomes ninety degrees perpendicular to the bottom plate 1, the strip plate 623 inside the containing groove 52 also moves upward under the push of the corresponding matching piece 711, and the push rod 622 is pushed by the strip plate 623 to drive the push block 621 to move axially along the inside of the three arc-shaped support pieces 614. The axial movement of the push block 621 pushes the three arc-shaped support pieces 614 to expand outward synchronously, thereby completing the internal expansion support work of the plastic rod. At this time, the stepper motor is controlled to stop working.
[0031] After the inner expansion work of the three arc-shaped support pieces 614 is completed, the annular cutting device 54 is controlled to extend the tool, and then the annular cutting device 54 is started to perform annular cutting on the plastic rods on the arc-shaped support pieces 614. After the cutting is completed, the stepper motor is started to continue to drive the partition chamber 5 to move. During the movement, the support plate 611 and the strip plate 623 gradually move away from the inverted T-shaped boss 71 and disengage from the corresponding matching piece 711. At this time, the support plate 611 and the strip plate 623 rebound and reset synchronously. The plastic rods without internal support are hung on the outer walls of the three arc-shaped support pieces 614 and reset to the inside of the receiving groove 52 with the support plate 611. Then, cold air is injected into the partition chamber 5 by external equipment to further cool the plastic rods.
[0032] It should be noted that the lengths of the two mating pieces 711 on the inverted T-shaped boss 71 are different, that is, the supporting plate 611 contacts and retracts with its corresponding mating piece 711 first, and after the supporting plate 611 retracts, the strip plate 623 rotates with the partition chamber 5 and gradually contacts and retracts with its corresponding mating piece 711.
[0033] After completing the cutting and separation of the first plastic rod, repeat the above work, continue to control the rotation of the separation bin 5 by the stepper motor and cooperate with the movement of subsequent plastic rods, and continuously complete the cutting and separation of the plastic rods. At the same time, when the support plate 611 drives the plastic rod that has been cut to reset, the plastic rod is concentric and coaxial with the circular hole 53 opened on the separation bin 5, which is convenient for the stable unloading work in the later stage. The arc-shaped expansion piece 615 arranged on the three arc-shaped support pieces 614 has a certain height difference with the arc-shaped support piece after popping out. The purpose is to use the height difference to prevent the annular cutting device 54 from damaging the arc-shaped support piece 614 when cutting the plastic rod.
[0034] Initial anti-adhesion work for plastic bars: Before the plastic extrusion equipment 2 extrude the plastic into the molding cavity 3, the external equipment is controlled to drive the linkage disk 314 and the annular sleeve 313 to rotate through two connecting rods. At the same time, the cooler 311 generates cold air and delivers it to the annular sleeve 313 through the delivery pipe 312. After cooling, the annular sleeve 313 continuously rotates and contacts with the initially formed plastic rod, thereby completing the initial cooling of the outer wall of the plastic rod, avoiding deformation, uneven cooling and other problems caused by the plastic rod with too high a temperature suddenly entering the cooling cavity 4.
[0035] Cutting work after plastic bar cutting: As the plastic rods inside the partition bin 5 are further cut and rotated to the position of the blanking inclined plate 724, the electric push rod 723 is controlled to extend and push the triangular pressure plate 721. At this time, the triangular pressure plate 721 is compressed and drives the connecting rod set thereon to move synchronously, and then pushes the top block 613 attached to the connecting rod. Under the push of the top block 613, the plastic rods pop out from the circular hole 53 to the blanking inclined plate 724, and finally move along the blanking inclined plate 724 to the blanking box 725 to complete collection.
[0036] It is worth noting that during the intermittent rotation of the partition chamber 5, the circular cutting of the plastic rods and the cutting of the materials are carried out simultaneously, which can reduce the idle period of the overall work and further improve the continuity of the plastic rod forming and cutting work.
[0037] The above-mentioned supporting assembly 61, inner support assembly 62 and anti-adhesion assembly 31 have the following advantages: Advantage 1: After being precisely cut by the annular cutting equipment 54, the plastic rod is smoothly moved to the containing groove 52 along with the supporting plate 611, and is firmly suspended on the outer walls of the three arc-shaped support plates 614. At the same time, the external equipment continuously injects cold air into the partition chamber 5 to achieve further uniform cooling of the plastic rod, ensure the uniform temperature distribution of the inner and outer walls, and improve the cooling quality and structural stability of the plastic rod.
[0038] Advantage 2: With the continuous rotation of the partition chamber 5, the cut plastic rods will be hung on the arc-shaped support pieces 614 of different support plates 611, effectively avoiding the pits and adhesion that may be generated after the contact between two adjacent plastic rods, thereby ensuring the surface quality of the finished plastic rods.
[0039] Advantage three, when the support plate 611 and the base plate 1 are in a vertical state of ninety degrees, the push block 621, under the pushing action of the strip plate 623, drives the three arc-shaped support pieces 614 to achieve synchronous outward expansion, which not only effectively completes the internal support work of the plastic rod, but also during the operation of the annular cutting equipment 54, the arc-shaped support pieces 614 exert a uniform internal support force on the inner wall of the plastic rod, which effectively prevents the rod from being deformed and improves the cutting accuracy and the quality of the finished product.
[0040] Advantage four: in the initial stage when the plastic rod enters the molding cavity 3, the annular sleeve 313 contacts the outer wall of the plastic rod, allowing the plastic rod to gradually adapt to the cooling temperature and effectively reduce its surface temperature, thereby significantly reducing the risk of deformation that may be caused when the plastic rod directly enters the cooling cavity 4 due to excessive temperature, and avoiding product quality defects caused by uneven cooling.
