Description

Technical Field

[0001] The utility model relates to the technical field of cooling heads for auxiliary molds of plastic particles, in particular to a cooling head for auxiliary molds of plastic particles which is easy to replace. Background Art

[0002] Plastic granulation equipment is used to make plastic raw materials into plastic particles. The basic working principle of plastic granulation equipment is the same, that is, the plastic raw materials are added to the screw extruder, the plastic raw materials are melted by heating, and then the screw in the screw extruder barrel extrude the material and extrude the melted plastic from the die head into thin strips, and then the thin strips are cooled by air or water and cut into plastic particles by blades.

[0003] Common plastic particle auxiliary mold cooling heads usually need to be replaced with cooling heads of different specifications according to processing requirements when in use, and existing cooling heads are usually installed with fixing bolts to ensure the stability of the connection, which makes it inconvenient to disassemble and assemble during replacement.

[0004] Therefore, the problem that the above-mentioned plastic particle auxiliary mold cooling head is not convenient to disassemble and replace during use needs to be solved urgently to improve the use scenario of the plastic particle auxiliary mold cooling head. Utility Model Content

[0005] In order to overcome the common plastic particle auxiliary mold cooling head, when using it, it is usually necessary to replace cooling heads of different specifications according to processing requirements to adjust the diameter of the extruded strip, and the existing cooling heads are usually installed with fixing bolts to ensure the stability of the connection, resulting in the problem of inconvenient disassembly and assembly during replacement.

[0006] The technical solution of the utility model is: a plastic particle auxiliary mold cooling head that is easy to replace, comprising an extrusion head, a cooling head body is arranged on the front side of the extrusion head, mutually symmetrical extrusion holes are penetrated through the front side surface of the extrusion head, a discharge hole is penetrated through the front side surface of the cooling head body, quick-release components are arranged at the edges and corners of the front side surface of the extrusion head, and the quick-release components include a base, a fixing rod, a buckle, a positioning hole and a first clamping block; mutually symmetrical bases are installed at the edges and corners of the front side surface of the extrusion head, a fixing rod is installed on the front side surface of the base, a first clamping block is installed at the front end of the fixing rod, mutually symmetrical positioning holes are opened at the edges and corners of the rear side surface of the cooling head body, and buckles are arranged inside the positioning holes.

[0007] Preferably, by providing a quick-release assembly, when installing the cooling head body, the positioning hole on the rear side of the cooling head body is aligned with the fixing rod on the front side of the extrusion head, and after insertion and pressing, the buckle can be engaged with the bottom position of the conical first clamping block, thereby achieving quick installation of the cooling head body, thereby solving the problem that the existing plastic particle auxiliary mold cooling head is usually fixed with fixing bolts during use, which is not convenient for replacement and installation.

[0008] Preferably, the quick-release assembly includes an installation groove and a cavity; installation grooves are provided on both sides of the left and right sides of the interior of the positioning hole, and a cavity is provided at the end of the installation groove away from the positioning hole. By providing the installation groove and the cavity, the sliding structure of the buckle can be easily installed and used.

[0009] Preferably, the quick-release assembly includes a slide rod and a spring; the slide rod is slidably connected to the inside of the installation groove, and the outer surface of the slide rod is sleeved with a spring, and the end of the slide rod close to the positioning hole is connected to the buckle. By arranging the slide rod and the spring, when the buckle is squeezed by the first clamping block, the buckle will drive the slide rod to slide along the installation groove. During the squeezing process, the spring will shrink. When the overall position of the buckle moves beyond the first clamping block, the spring will rebound and push the buckle out again, thereby completing the engagement.

[0010] Preferably, the quick-release assembly includes a limiting ring; a limiting ring is arranged at the connection between the mounting groove and the cavity, the sliding rod is slidably connected to the inner ring of the limiting ring, and the end of the spring away from the positioning hole is fixedly connected to the limiting ring.

At this time, the spring contracts, and the buckle will slide along the outer surface of the second clamping block until it contacts the bottom of the first clamping block. Since the first clamping block is conical, the buckle will continue to slide along the surface of the first clamping block under the rebound action of the spring until the cooling head body is separated from the extrusion head, thereby realizing quick release.

[0012] Preferably, a sealing seat is installed at the front end of the inner surface of the extrusion hole, and a sealing ring is installed at the rear surface of the discharge hole. The sealing seat matches the sealing ring. By setting the sealing seat and the sealing ring, the sealing effect between the extrusion hole and the discharge hole can be increased to prevent leakage of the plastic solution.

[0013] Preferably, electric push rods are installed on the left and right side surfaces of the extrusion head, nuts are installed on the telescopic ends of the electric push rods, and a pressure rod is threadedly connected to the inner surface of the nut. After docking, the pressure rod is moved to a horizontal position and the electric push rod is started to drive the pressure rod to move to one side of the extrusion head, thereby achieving the function of auxiliary fixation of the cooling head body.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting a quick-release assembly, when installing the cooling head body, align the positioning hole on the rear side of the cooling head body with the fixing rod on the front side of the extruder head, insert and press, so that the buckle can be engaged with the bottom position of the conical first clamping block, thereby realizing the rapid installation of the cooling head body, thereby solving the problem that the existing plastic particle auxiliary mold cooling head is usually fixed with fixing bolts during use, which is inconvenient to replace and install;

[0016] 2. By setting a sliding rod and a spring, when the buckle is squeezed by the first clamping block, the buckle will drive the sliding rod to slide along the installation groove. During the squeezing process, the spring will contract. When the overall position of the buckle moves beyond the first clamping block, the spring will rebound and push the buckle out again, thereby completing the engagement. And by setting a second clamping block, when the cooling head body needs to be disassembled, the cooling head body can be pressed again so that the buckle moves beyond the second clamping block, and then the cooling head body is pulled outward. The second clamping block will be driven by the buckle to slide along the fixed rod until it fits with the bottom of the first clamping block. At this time, the spring contracts, and the buckle will slide along the outer surface of the second clamping block until it contacts the bottom of the first clamping block. Since the first clamping block is conical, the buckle will continue to slide along the surface of the first clamping block under the rebound action of the spring until the cooling head body is separated from the extrusion head, thereby realizing quick release.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figure 1-Figure 3 The utility model provides an embodiment: a plastic particle auxiliary mold cooling head that is easy to replace, including an extrusion head 1, a cooling head body 2 is arranged on the front side of the extrusion head 1, and mutually symmetrical extrusion holes 3 are opened through the front side surface of the extrusion head 1, and a discharge hole 4 is opened through the front side surface of the cooling head body 2. Quick-release components are arranged at the corners of the front side surface of the extrusion head 1, and the quick-release components include a base 51, a fixing rod 52, a buckle 53, a positioning hole 59 and a first clamping block 510; mutually symmetrical bases 51 are installed at the corners of the front side surface of the extrusion head 1, a fixing rod 52 is installed on the front side surface of the base 51, and a first clamping block 510 is installed at the front end of the fixing rod 52, and mutually symmetrical positioning holes 59 are opened at the corners of the rear side surface of the cooling head body 2, and buckles 53 are arranged inside the positioning holes 59.

[0025] See also Figure 1-Figure 5In this embodiment, the quick release assembly includes a mounting groove 54 and a cavity 55; mounting grooves 54 are provided on both sides of the interior of the positioning hole 59, and a cavity 55 is provided at one end of the mounting groove 54 away from the positioning hole 59. By providing the mounting groove 54 and the cavity 55, the sliding structure of the buckle 53 can be easily installed and used, and the quick release assembly includes a slide bar 57 and a spring 58; the interior of the mounting groove 54 is slidably connected with a slide bar 57, and the outer surface of the slide bar 57 is sleeved with a spring 58. One end of the slide bar 57 close to the positioning hole 59 is connected to the buckle 53. By providing the slide bar 57 and the spring 58, when the buckle 53 is squeezed by the first clamping block 510, the buckle 53 will drive the slide bar 57 to slide. The rod 57 slides along the mounting groove 54. During the extrusion process, the spring 58 will shrink. When the overall position of the buckle 53 moves beyond the first block 510, the spring 58 will rebound and push the buckle 53 out again, thereby completing the engagement. The quick release assembly includes a limiting ring 56. A limiting ring 56 is provided at the connection between the mounting groove 54 and the cavity 55. The sliding rod 57 is slidably connected to the inner ring of the limiting ring 56. The end of the spring 58 away from the positioning hole 59 is fixedly connected to the limiting ring 56. By providing the limiting ring 56, the end of the spring 58 away from the buckle 53 can be fixed to avoid the synchronous sliding of the spring 58 when the sliding rod 57 slides, resulting in the problem of failure to engage.

[0026] See also Figure 1-Figure 5In this embodiment, the quick-release assembly includes a second clamping block 511; a second clamping block 511 is provided on one side of the outer surface of the fixing rod 52 close to the base 51, and the second clamping block 511 is slidably connected to the fixing rod 52. By providing the second clamping block 511, when the cooling head body 2 needs to be disassembled, the cooling head body 2 can be pressed again so that the buckle 53 moves beyond the second clamping block 511, and then the cooling head body 2 is pulled outward, and the second clamping block 511 is driven by the buckle 53 to slide along the fixing rod 52 until it fits with the bottom of the first clamping block 510. At this time, the spring 58 contracts, and the buckle 53 slides along the outer surface of the second clamping block 511 until it contacts with the bottom of the first clamping block 510. Since the first clamping block 510 is conical, the buckle 53 rebounds during the spring 58. Under the action, it will continue to slide along the surface of the first clamping block 510 until the cooling head body 2 is separated from the extrusion head 1, thereby realizing quick disassembly, and a sealing seat 6 is installed at the front end of the inner surface of the extrusion hole 3, and a sealing ring 7 is installed on the rear surface of the discharge hole 4, and the sealing seat 6 matches the sealing ring 7. By setting the sealing seat 6 and the sealing ring 7, the sealing effect between the extrusion hole 3 and the discharge hole 4 can be increased to prevent the plastic solution from leaking out, and electric push rods 8 are installed on the left and right side surfaces of the extrusion head 1, and nuts 9 are installed at the telescopic ends of the electric push rods 8. The inner surface of the nut 9 is threadedly connected with a pressure rod 10. After docking, the pressure rod 10 is moved to a horizontal position, and the electric push rod 8 is started, which can drive the pressure rod 10 to move to one side of the extrusion head 1, thereby realizing the auxiliary fixation of the cooling head body 2.

[0027] When working, by providing the installation groove 54 and the cavity 55, it is convenient to install and use the sliding structure of the buckle 53, and by providing the sliding rod 57 and the spring 58, when the buckle 53 is squeezed by the first clamping block 510, the buckle 53 will drive the sliding rod 57 to slide along the installation groove 54. During the squeezing process, the spring 58 will shrink. When the overall position of the buckle 53 moves beyond the first clamping block 510, the spring 58 will rebound and push the buckle 53 out again, thereby completing the engagement. In addition, by providing the limiting ring 56, the end of the spring 58 away from the buckle 53 can be fixed to prevent the spring 58 from sliding synchronously when the sliding rod 57 slides, resulting in the problem of failure to engage. In addition, by providing the second clamping block 511, when the cooling head body 2 needs to be disassembled, the cooling head body 2 can be pressed again to make the buckle 53 move beyond the second clamping block 511. The clamping block 511 is then pulled outward to pull the cooling head body 2, and the second clamping block 511 is driven by the buckle 53 to slide along the fixing rod 52 until it fits with the bottom of the first clamping block 510. At this time, the spring 58 contracts, and the buckle 53 slides along the outer surface of the second clamping block 511 until it contacts with the bottom of the first clamping block 510. Since the first clamping block 510 is conical, the buckle 53 will continue to slide along the surface of the first clamping block 510 under the rebound action of the spring 58 until the cooling head body 2 is separated from the extrusion head 1, thereby realizing quick release, and by providing the sealing seat 6 and the sealing ring 7, the sealing effect between the extrusion hole 3 and the discharge hole 4 can be increased to prevent the plastic solution from leaking out, and after docking, the pressure rod 10 is moved to the horizontal position, and the electric push rod 8 is started, which can drive the pressure rod 10 to move to one side of the extrusion head 1, thereby realizing the auxiliary fixation of the cooling head body 2.

[0028] Through the above steps, by setting up a quick-release assembly, when installing the cooling head body 2, align the positioning hole 59 on the rear side of the cooling head body 2 with the fixing rod 52 on the front side of the extrusion head 1, and press after insertion, so that the buckle 53 can be engaged with the bottom position of the conical first block 510, thereby realizing the rapid installation of the cooling head body 2, thereby solving the problem that the existing plastic particle auxiliary mold cooling head is usually fixed with fixing bolts during use, which is not convenient for replacement and installation.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
