Description

Technical Field

[0001] The present invention relates to the technical field of plastic rod extrusion and shaping, and particularly relates to a plastic rod extrusion and shaping device with an anti-adhesion structure. Background Art

[0002] As a common plastic product, in the plastic rod forming work, extrusion molding is one of the main methods for producing plastic rods. After melting and plasticizing plastic raw materials through an extruder, the plastic is continuously extruded through a screw and formed into a rod of the required shape through a die. Among many plastic rods, there is a relatively special one, namely a plastic hollow rod, which has a hollow structure inside. In some cases, the hollow structure inside can be used to provide better bending strength and stiffness, and the hollow part can be used for conveying or protecting wire rods.

[0003] The production of the above-mentioned plastic hollow rods is generally the same as that of common plastic rods except for the die. However, it should be noted that after the plastic hollow rods are formed, they are conveyed to a cooling cavity during continuous extrusion for cooling and shaping treatment. However, due to the continuous extrusion operation, during the non-stop forward movement of the plastic hollow rods, the cooling effects on their inner and outer walls are likely to be inconsistent. When the cut plastic hollow rods freely fall into the material placing box under the action of gravity, due to the difference in the cooling effects on the inner and outer walls, adjacent rods are extremely likely to produce pit defects after collision. In addition, as the rods are further cooled in the room temperature environment, the problem of mutual adhesion also appears, which has an adverse impact on the surface quality and subsequent processing of the plastic hollow rods. Summary of the Invention

[0004] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a plastic rod extrusion and shaping device with an anti-adhesion structure, which can effectively solve the problems in the prior art that the cooling effects on the inner and outer walls of plastic rods are inconsistent during the moving and cooling process, adjacent two plastic rods collide to produce pits, and adhesion occurs.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0006] The present invention provides a plastic rod extrusion and shaping device with an anti-adhesion structure, including: a bottom plate, on the upper end surface of which a plastic extrusion device is fixedly installed by means of bolts and nuts. An end of the plastic extrusion device is cooperatively provided with a forming cavity, which converts plastic into a rod shape, and an anti-adhesion component for preventing the plastic rod from adhering to the inner wall of the forming cavity is installed on the forming cavity;

[0007] At one end of the forming cavity away from the plastic extrusion equipment, a cooling cavity and a separation bin are installed. The plastic rod first passes through the cooling cavity and is guided by an external conveying device to move into the separation bin. Moreover, a matching mechanism for assisting the operation of the separation bin is also provided on the upper end surface of the bottom plate;

[0008] Among them, the separation bin is rotatably connected to the bottom plate through a support seat and is intermittently rotated by an external stepping motor. The inside of the separation bin is set as a cavity structure, and a number of placing grooves for placing plastic rods are arranged along the circumferential direction inside the cavity. An auxiliary mechanism is arranged inside the placing groove;

[0009] The auxiliary mechanism includes a supporting component installed inside the placing groove and cooperating with the matching mechanism. An inner supporting component is also installed on the supporting component. The inner supporting component completes the inner supporting work on the inner wall of the plastic rod to prevent its inner wall from deforming during the forming process.

[0010] Furthermore, circular holes are arranged along the circumferential direction on the end face of the separation bin close to the external conveying device corresponding to the positions of the placing grooves. An annular cutting device is installed at the central positions of a number of circular holes. An annular groove is arranged on the inner wall of the separation bin and on the side far from the annular cutting device. The annular groove is conical and its diameter gradually decreases from the outside to the center position. A strip-shaped groove is arranged on the annular inner wall of the annular groove corresponding to the position of the placing groove, and one end of the strip-shaped groove far from the annular groove penetrates through the separation bin.

[0011] Furthermore, the supporting component includes a supporting plate slidably arranged inside the placing groove. The supporting plate is fixedly connected to the placing groove through a spring. Two sets of sliding grooves extending in different directions are arranged at the top end of the supporting plate. Each set of sliding grooves includes three strip-shaped sliding grooves. Among them, sliding blocks are slidably arranged inside the three strip-shaped sliding grooves extending in the vertical direction. The sliding blocks are fixedly connected to the strip-shaped sliding grooves through springs. Top blocks are slidably arranged inside the three strip-shaped sliding grooves extending in the horizontal direction. The top blocks are also fixedly connected to the corresponding strip-shaped sliding grooves through springs. An arc-shaped supporting piece for inner support of the plastic rod is fixedly arranged on the end face of the sliding block. Arc-shaped telescopic pieces are respectively fixedly arranged at one ends of the three arc-shaped supporting pieces far from the supporting plate.

[0012] Furthermore, the inner supporting component includes a pushing block. The pushing block is fixedly arranged on the end face of the supporting plate through a spring. A top rod penetrating through the supporting plate is fixedly arranged at one end of the pushing block close to the supporting plate. A chamfer one is arranged at one end of the top rod passing through the supporting plate. A strip-shaped plate with a chamfer two is arranged in cooperation with the side of the top rod provided with the chamfer one. The strip-shaped plate is fixedly arranged inside the strip-shaped groove through a spring.

[0013] Furthermore, the inner side walls of the three arc-shaped supporting pieces are sloped, that is, the diameter of the inner side wall of the arc-shaped supporting piece gradually decreases from the side close to the supporting plate to the side far from the supporting plate. The top rod and the pushing block are arranged inside the three arc-shaped supporting pieces, and the outer wall of the pushing block is set as a conical outer wall matching the sloped inner wall of the arc-shaped supporting piece.

[0014] Further, the anti-sticking component includes a cooler sleeved on the outer wall of the forming cavity. The cooler is rotationally connected through a conveying pipe penetrating the forming cavity to an annular sleeve with an anti-sticking coating on its inner wall. The outer wall of the annular sleeve is fixedly connected to a linkage disk through a connecting rod, and the linkage disk is fixedly connected to an external driving device through two connecting rods.

[0015] Further, the matching mechanism includes an inverted T-shaped boss and a blanking component arranged on the upper end surface of the bottom plate. The inverted T-shaped boss is fixedly arranged on the upper end surface of the bottom plate, and two matching pieces corresponding to the positions of the supporting plates and the strip-shaped plate are fixedly arranged at the top of the inverted T-shaped boss.

[0016] Further, the blanking component includes a plurality of triangular pressing plates distributed along the circumference and fixedly arranged on the right end surface of the partition bin through springs. Connecting rods penetrating the partition bin are fixedly arranged at the three corners of the triangular pressing plates. The three connecting rods are arranged corresponding to the positions of the top blocks and are respectively in contact with the corresponding top blocks. An installation plate is fixedly arranged on the upper end surface of the bottom plate, and an electric push rod for intermittently pushing the triangular pressing plates is fixedly arranged on the installation plate. The blanking component further includes a blanking inclined plate and a blanking box fixedly arranged on the upper end surface of the bottom plate. The blanking inclined plate and the blanking box are both installed on the left side wall of the partition bin and are used for collecting the plastic rods after blanking.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the prior art:

[0018] The present invention is provided with an anti-sticking component, which can realize that before the plastic rod enters the cooling cavity, the annular sleeve makes the plastic rod gradually adapt to the cooling temperature through contact with the outer wall of the plastic rod, effectively reducing its surface temperature, thereby significantly reducing the deformation risk that may be caused when directly entering the cooling cavity due to too high temperature. When the plastic rod enters the partition bin for cutting work, the synchronous outward expansion of the three arc-shaped support pieces ensures the stability of the plastic rod during the cutting work, effectively preventing the plastic rod from deforming under pressure. Finally, the partition bin separates the cut plastic rods and injects cold air to achieve further uniform cooling of the plastic rods, and at the same time, it can also avoid the pit situation generated by the collision during the contact of adjacent two plastic rods.

[0035] One end of the forming cavity 3 away from the plastic extrusion device 2 is provided with a cooling cavity 4 and a separation bin 5. The plastic rod first passes through the cooling cavity 4 and is guided by an external conveying device to move into the separation bin 5. Moreover, a matching mechanism 7 for assisting the work of the separation bin 5 is also provided on the upper end surface of the bottom plate 1;

[0036] Among them, the separation bin 5 is rotatably connected to the bottom plate 1 through a support seat 51 and is intermittently rotated by an external stepping motor. The interior of the separation bin 5 is of a cavity structure, and a plurality of placing grooves 52 for placing plastic rods are opened along the circumferential direction in the cavity.

[0037] The auxiliary mechanism 6 includes a supporting component 61 installed inside the placing groove 52 and cooperating with the matching mechanism 7. An inner support component 62 is also installed on the supporting component 61. The inner support component 62 completes the inner support work on the inner wall of the plastic rod to prevent its inner wall from deforming during the forming process;

[0038] On the end face of the separation bin 5 close to the external conveying device, circular holes 53 are opened along the circumferential direction corresponding to the positions of the placing grooves 52. A ring cutting device 54 is installed at the central positions of the plurality of circular holes 53. An annular groove is opened on the inner wall of the separation bin 5 and away from the ring cutting device 54. The annular groove is conical and the diameter gradually decreases from the outside to the center position. A strip-shaped groove 55 is opened on the annular inner wall of the annular groove corresponding to the position of the placing groove 52, and one end of the strip-shaped groove 55 away from the annular groove penetrates through the separation bin 5.

[0039] The supporting component 61 includes a supporting plate 611 slidably arranged inside the containing groove 52. The supporting plate 611 is fixedly connected to the containing groove 52 through a spring. Two chute groups extending in different directions are formed at the top end of the supporting plate 611. Each chute group includes three strip-shaped chutes. Among them, sliding blocks 612 are slidably arranged inside the three strip-shaped chutes extending in the vertical direction. The sliding blocks 612 are fixedly connected to the strip-shaped chutes through springs. Top blocks 613 are slidably arranged inside the three strip-shaped chutes extending in the horizontal direction. The top blocks 613 are also fixedly connected to the corresponding strip-shaped chutes through springs. An arc-shaped support piece 614 for the internal support of the plastic rod is fixedly arranged on the end face of the sliding block 612. Arc-shaped telescopic pieces 615 are respectively fixedly arranged at one ends of the three arc-shaped support pieces 614 away from the supporting plate 611.

[0040] The internal support component 62 includes a pushing block 621. The pushing block 621 is fixedly arranged on the end face of the supporting plate 611 through a spring. A top rod 622 penetrating the supporting plate 611 is fixedly arranged at one end of the pushing block 621 close to the supporting plate 611. A chamfer one is formed at one end of the top rod 622 passing through the supporting plate 611. A strip-shaped plate 623 with a chamfer two is arranged in cooperation with the side of the top rod 622 where the chamfer one is formed. The strip-shaped plate 623 is fixedly arranged inside the strip-shaped groove 55 through a spring.

[0041] The inner side walls of the three arc-shaped support pieces 614 are in a slope shape, that is, the diameter of the inner side wall of the arc-shaped support piece 614 gradually decreases from the side close to the supporting plate 611 to the side away from the supporting plate 611. The top rod 622 and the pushing block 621 are arranged inside the three arc-shaped support pieces 614, and the outer wall of the pushing block 621 is arranged as a conical outer wall that matches the slope-shaped inner wall of the arc-shaped support piece 614.

[0042] The anti-adhesion component 31 includes a cooler 311 sleeved on the outer wall of the forming cavity 3. The cooler 311 is rotatably connected through a conveying pipe 312 penetrating the forming cavity 3 to an annular sleeve 313 with an anti-adhesion coating on its inner wall. The outer wall of the annular sleeve 313 is fixedly connected to a linkage disk 314 through a connecting rod. The linkage disk 314 is fixedly connected to an external driving device through two connecting rods.

[0043] The matching mechanism 7 includes an inverted T-shaped boss 71 and a blanking component 72 arranged on the upper end face of the bottom plate 1. The inverted T-shaped boss 71 is fixedly arranged on the upper end face of the bottom plate 1, and two matching pieces 711 corresponding to the positions of the supporting plate 611 and the strip-shaped plate 623 are fixedly arranged at the top end of the inverted T-shaped boss 71.

[0044] The blanking assembly 72 includes several triangular pressing plates 721 that are distributed along the circumference and fixedly arranged on the right end face of the partition bin 5 by springs. Connecting rods penetrating through the partition bin 5 are fixedly arranged at the three corners of the triangular pressing plate 721. The three connecting rods are arranged corresponding to the position of the top blocks 613 and are respectively in contact with the corresponding top blocks 613. An installation plate 722 is fixedly arranged on the upper end face of the bottom plate 1. An electric push rod 723 for intermittently pushing the triangular pressing plate 721 is fixedly arranged on the installation plate 722. The blanking assembly 72 further includes a blanking inclined plate 724 and a blanking box 725 fixedly arranged on the upper end face of the bottom plate 1. The blanking inclined plate 724 and the blanking box 725 are both installed on the left side wall of the partition bin 5 and are used for the collection work after the plastic rods are blanked.

[0045] Reference Figures 1 - 9 , the formed plastic hollow rods are conveyed to the cooling cavity 4 during continuous extrusion for cooling and shaping. However, due to the continuous extrusion operation, during the non-stop forward movement of the plastic hollow rods, the cooling effects on their inner and outer walls are prone to be inconsistent. When the cut plastic hollow rods freely fall to the material placement box under the action of gravity, due to the difference in cooling effects on the inner and outer walls, adjacent rods are extremely prone to generate pit defects after collision. In addition, as the rods are further cooled in the room temperature environment, the problem of mutual adhesion also appears, which has an adverse impact on the surface quality and subsequent processing of the plastic rods;

[0046] In order to overcome the above-mentioned existing defects, this application designs a plastic rod extrusion and shaping device with an anti-adhesion structure, which can not only effectively avoid the bumps and pits caused by uneven internal and external cooling effects after plastic forming, but also avoid the adhesion problem between adjacent two rods after cooling at room temperature.

[0047] Cutting and partitioning of plastic rods:

[0048] Initially, start the external stepping motor to drive the partition bin 5 to rotate intermittently. When the partition bin 5 rotates above the inverted T-shaped boss 71, the supporting plate 611 first contacts the matching piece 711 arranged on the inverted T-shaped boss 71. At this time, the supporting plate 611 is gradually pushed and compressed by the matching piece 711, and thus retracts into the partition bin 5.

[0049] When the supporting plate 611 is being compressed, the three arc-shaped supporting pieces 614 arranged on it move upward synchronously until they move to the center position of the partition bin 5. At this time, the arc-shaped telescopic pieces 615 arranged on the three arc-shaped supporting pieces 614 quickly pop out due to the lack of support.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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 614 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.

[0054] Initial anti-adhesion work for plastic bars:

[0055] Before the plastic extrusion equipment 2 extrudes plastic into the forming cavity 3, it controls the external equipment to drive the linkage disk 314 and the annular sleeve 313 to rotate through two connecting rods. At the same time, the cooling machine 311 generates cold air and transports it to the annular sleeve 313 through the delivery pipe 312. After the annular sleeve 313 is cooled down, it continuously rotates and contacts the preliminarily formed plastic rod, thus completing the preliminary cooling work on the outer wall of the plastic rod and avoiding problems such as deformation and uneven cooling caused by the plastic rod with too high temperature suddenly entering the cooling cavity 4.

[0056] The blanking work after the plastic rod is cut:

[0057] As the plastic rod inside the partition bin 5 is further cut and rotates to the position of the blanking inclined plate 724, it controls the electric push rod 723 to extend and push the triangular pressing plate 721. At this time, after the triangular pressing plate 721 is compressed, it drives the connecting rod arranged on it to move synchronously, and then pushes the top block 613 that is in contact with the connecting rod. The plastic rod is pushed by the top block 613 and pops out from the circular hole 53 to the blanking inclined plate 724, and finally moves along the blanking inclined plate 724 to the blanking box 725 to complete the collection.

[0058] It should be noted that during the intermittent rotation of the partition bin 5, the simultaneous circumferential cutting and blanking work of the plastic rod can reduce the idle period of the overall work, and then improve the coherence of the plastic rod forming and blanking work.

[0059] The above-mentioned use of the supporting component 61, the inner support component 62 and the anti-adhesion component 31 has the following advantages:

[0060] Advantage 1: After being accurately cut by the annular cutting equipment 54, the plastic rod moves smoothly to the storage tank 52 along the supporting plate 611 and is firmly suspended on the outer wall of the three arc-shaped support pieces 614. At the same time, the external equipment continuously injects cold air into the partition bin 5 to further uniformly cool the plastic rod, ensuring uniform temperature distribution on its inner and outer walls and improving the cooling quality and structural stability of the plastic rod.

[0061] Advantage 2: As the partition bin 5 continues to rotate, the cut plastic rods will be respectively hung on the arc-shaped support pieces 614 of different supporting plates 611, effectively avoiding the possible concave pits and adhesion phenomena after the adjacent two plastic rods come into contact, and ensuring the surface quality of the plastic rod finished product.

[0062] Advantage 3: When the supporting plate 611 is perpendicular to the bottom plate 1 at a right angle of 90 degrees, the pushing block 621 drives the three arc-shaped support pieces 614 to expand synchronously under the pushing action of the strip-shaped plate 623. This not only effectively completes the inner support work of the plastic rod, but also during the operation of the annular cutting equipment 54, through the uniform inner support force exerted by the arc-shaped support pieces 614 on the inner wall of the plastic rod, effectively prevents the rod from deforming and improves the cutting accuracy and finished product quality.

[0063] Advantage 4: In the initial stage when the plastic bar enters the forming cavity 3, through the contact between the annular sleeve 313 and the outer wall of the plastic bar, the plastic bar gradually adapts to the cooling temperature, effectively reducing its surface temperature, thus significantly reducing the risk of deformation that may occur when directly entering the cooling cavity 4 due to excessive temperature, and avoiding product quality defects caused by uneven cooling.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
