Description

Technical Field

[0001] This utility model relates to a cooling device, specifically a plastic extrusion cooling device, belonging to the field of plastic extrusion cooling technology. Background Technology

[0002] In the processing of plastics, the raw materials need to be heated and mixed. The mixed plastic is in a liquid state and is conveyed through the extrusion port to a cooling tank for cooling and plasticization before finally being cut. In plastic extrusion production, the material is first extruded through a screw extruder to obtain a linear melt, i.e., a plastic strip. Since the plastic strip is still in the plastic stage after being extruded from the screw extruder, it needs to be cooled with cold water.

[0003] However, when guide rollers are installed in the cooling water tank to guide the conveying of plastic strips, the position of the guide rollers needs to be adjusted when producing plastic strips of different widths or thicknesses. The guide roller mounting bracket is usually fixed to the side wall of the cooling water tank with positioning bolts, which is inconvenient to fix the guide rollers. After long-term use, the guide roller mounting bracket may loosen, which may also affect the conveying effect of the guide rollers, thus hindering the improvement of the efficiency of the cooling water tank. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic extrusion cooling device to solve the above problems. The handle drives the slider to slide in the card holder, and when the slider drives the connecting rod to slide, it squeezes the telescopic spring. The connecting rod drives the end of the card rod to slide out from the insert block and the card holder, which makes it easier to remove the card holder from the cooling tank, thereby making it easier for the operator to adjust the position of the guide roller on the card holder.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a plastic extrusion cooling device includes a cooling tank, on which a filtering mechanism and an installation mechanism are fixed. Two sets of slots and locking holes are symmetrically arranged at the top of the cooling tank. A guide mechanism is engaged and installed on the cooling tank. The guide mechanism includes a bracket and an insert block. Two sets of brackets are engaged and installed inside the cooling tank. A guide roller is rotatably connected to the bracket. An insert block is fixedly connected to the bracket and engaged with the cooling tank. A connecting rod is slidably connected to the bracket. A telescopic spring is sleeved on the connecting rod. A slider is fixedly installed at one end of the connecting rod, and a handle is fixedly connected to the top of the slider. A locking rod is rotatably installed at the other end of the connecting rod and engaged with the bracket.

[0006] Preferably, the two ends of the telescopic spring are fixedly connected to the card holder and the slider respectively, and the lengths of the two sets of card holders are not equal.

[0007] Preferably, the insert is located in the slot, and the part of the insert that engages with the cooling groove has an inclined structure.

[0008] Preferably, the locking rod penetrates the inner wall of the cooling tank and engages with the insert block, and the end of the locking rod is configured with a regular hexagonal structure.

[0009] Preferably, the filtration mechanism includes filter cylinders and rotating blocks. Several filter cylinders are threadedly installed in the cooling tank. The top of each filter cylinder is fixedly connected to a rotating block. A water storage tank and several drain pipes are fixedly installed on the cooling tank. Several mounting slots are provided inside the cooling tank.

[0010] Preferably, the drain pipe is located in the cooling tank near the mounting tank, and the bottom end of the filter cartridge is connected to the interior of the drain pipe.

[0011] Preferably, the inner wall of the rotating block is configured in a regular hexagonal shape, and the bottom end of the filter cartridge abuts against the top end of the drain pipe.

[0012] Preferably, the cooling tank is connected to the interior of the water storage tank via a drain pipe, and the water storage tank is located at the center of the bottom end of the cooling tank.

[0013] Preferably, the mounting mechanism includes partitions and rotating rollers, with two partitions fixedly connected to the cooling tank and rotating rollers rotatably mounted on the partitions.

[0014] Preferably, the mounting mechanism further includes a fiber sponge, and a fiber sponge is fixedly installed at one end of the cooling tank, the fiber sponge being arranged in an arc-shaped structure.

[0015] The beneficial effects of this utility model are as follows: When installing the card holder, the operator can first pull the handle fixed at the top of the slider. A connecting rod is fixedly installed on the slider. The handle drives the slider to move, causing the slider to squeeze the telescopic spring sleeved on the connecting rod. When the telescopic spring is in a compressed state, the connecting rod can drive the card rod, which is rotatably installed at the end, to slide out from the insert block and the card holder. At this time, the card holder is engaged and installed in the cooling tank. Since the top of the cooling tank is provided with two sets of slots and locking holes, the card holder drives the insert block to engage and install in the slot, thereby limiting the slot to the insert block. Then, the handle is released, and the connecting rod, under the reaction force of the telescopic spring, drives the card rod to engage in the card holder, the cooling tank, and the insert block. The card holder can then be limited by the card rod, thereby adjusting the position of the guide roller rotatably installed on the card holder. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7As shown, a plastic extrusion cooling device includes a cooling tank 1, characterized in that: a filter mechanism 2 and an installation mechanism 3 are fixed on the cooling tank 1; two sets of slots 4 and locking holes 5 are symmetrically provided at the top of the cooling tank 1; a guide mechanism 6 is engaged and installed on the cooling tank 1; the guide mechanism 6 includes a bracket 601 and an insert block 605; a bracket 601 is engaged and installed inside the cooling tank 1; the two sets of brackets 601 have unequal lengths; and a guide roller 602 is rotatably connected to the bracket 601. A plug 605 is fixedly connected to the card holder 601. The plug 605 is located in the slot 4 and engages with the cooling tank 1. The engagement part of the plug 605 with the cooling tank 1 is designed with an inclined structure, which can position the card holder 601. A connecting rod 607 is slidably connected to the card holder 601. A telescopic spring 608 is sleeved on the connecting rod 607. A slider 603 is fixedly installed at one end of the connecting rod 607. The top end of the slider 603 is fixedly connected to... A handle 604 is attached, and a locking rod 606 is rotatably mounted on the other end of the connecting rod 607. The locking rod 606 is engaged with the locking frame 601. The handle 604 drives the slider 603 to move, causing the slider 603 to compress the telescopic spring 608. When the telescopic spring 608 is in a compressed state, the connecting rod 607 can drive the locking rod 606, which is rotatably mounted at its end, to slide out from the insert block 605 and the locking frame 601. The two ends of the telescopic spring 608 are respectively connected to the locking frame 601 and the slider 603. The components are fixedly connected. The locking rod 606 penetrates the inner wall of the cooling tank 1 and engages with the insert block 605. The end of the locking rod 606 is hexagonal. When the handle 604 is released, the connecting rod 607, under the reaction force of the telescopic spring 608, drives the locking rod 606 to engage with the card holder 601, the cooling tank 1 and the insert block 605. The card holder 601 can be limited by the locking rod 606, thereby adjusting the position of the guide roller 602 rotatably mounted on the card holder 601.

[0026] As a technical optimization of this utility model, the filtration mechanism 2 includes a filter cylinder 203 and a rotating block 204. Several filter cylinders 203 are threadedly installed inside the cooling tank 1. The rotating block 204 is fixedly connected to the top of each filter cylinder 203. When water is discharged from the cooling tank 1, impurities in the water can be screened out and stored inside the filter cylinders 203. By rotating the rotating block 204 with a tool, the filter cylinders 203 can be rotated out of the mounting slot 205, thereby cleaning the impurities collected inside the filter cylinders 203. A storage device is fixedly installed on the cooling tank 1. The cooling tank 1 has a water tank 201 and several drain pipes 202. Several mounting slots 205 are provided inside the cooling tank 1. The drain pipes 202 are located in the cooling tank 1 near the mounting slots 205. The bottom end of the filter cylinder 203 is connected to the inside of the drain pipe 202. The inner wall of the rotating block 204 is arranged in a regular hexagonal structure. The cooling tank 1 is connected to the inside of the water storage tank 201 through the drain pipes 202. The filtered water can flow into the water storage tank 201 through the drain pipes 202 for storage. Then, the water in the water storage tank 201 can be recycled by a circulation pump.

[0027] As a technical optimization of this utility model, the installation mechanism 3 includes a partition 301 and a rotating roller 302. Two partitions 301 are fixedly connected to the cooling tank 1, and the rotating roller 302 is rotatably installed on the partitions 301. The arrangement of the two partitions 301 can distinguish the water in different parts of the cooling tank 1, so that the plastic strip is cooled more thoroughly. A fiber sponge 303 is fixedly installed at one end of the cooling tank 1. The fiber sponge 303 is arranged with an arc surface structure. When the plastic strip slides out along the guide roller 602 close to the fiber sponge 303, the fiber sponge 303 can absorb excess water on the plastic strip.

[0028] In use, when installing the card holder 601, the operator can first pull the handle 604 fixed at the top of the slider 603. A connecting rod 607 is fixedly installed on the slider 603. The handle 604 drives the slider 603 to move, causing the slider 603 to compress the telescopic spring 608 sleeved on the connecting rod 607. When the telescopic spring 608 is in a compressed state, the connecting rod 607 can drive the locking rod 606, which is rotatably installed at its end, to slide out from the insert block 605 and the card holder 601. At this time, the card holder 601 is engaged and installed into the cooling tank 1. Since the top of the cooling tank 1 has two sets of slots 4 and locking holes 5, the card holder 601 drives the insert block 605 to engage and install into the slot 4, so that the slot 4 limits the insertion block 605. Then, the handle 604 is released, and the connecting rod 607, under the reaction force of the telescopic spring 608, drives the locking rod 606 to engage into the card holder 601, the cooling tank 1, and the insert block 605. The clamp rod 606 can then limit the clamp holder 601, thereby adjusting the position of the guide roller 602 rotatably mounted on the clamp holder 601. When the plastic strip is extruded, it is conveyed into the cooling tank 1 and placed in the guide roller 602. Multiple plastic strips can be conveyed simultaneously. The two partitions 301 installed in the cooling tank 1 can also separate the water in different parts of the cooling tank 1, so that the plastic strip is cooled more thoroughly. When the plastic strip slides out along the guide roller 602 near the fiber sponge 303, the fiber sponge 303 can absorb the excess water on the plastic strip. When the water in the cooling tank 1 is discharged, the filter cartridge 203 can screen out the impurities in the water and store them inside. Then, the filtered water can flow into the water storage tank 201 through the drain pipe 202 for storage. Then, the water in the water storage tank 201 can be recycled by the circulation pump.
