Description

Technical Field

[0001] The utility model relates to a water-cooling and water-draining device for PVC plastic extrusion strips, belonging to the technical field of PVC plastic processing equipment. Background Technique

[0002] PVC plastic particles, also known as polyvinyl chloride particles, are a kind of plastic raw materials widely used in multiple industries. They are made from polyvinyl chloride resin through special processing techniques and have good physical properties and chemical stability. Due to their advantages such as weather resistance, chemical stability, electrical insulation, economy, and airtightness, PVC particles are widely used in many fields. After being stirred, PVC plastic particles enter an extruder. Inside the extruder, the plastic is heated to a molten state through high temperature and high pressure, and then extruded through an extrusion head to form the required profiles or sheets. In this process, in order to quickly reduce the temperature of the plastic, it is necessary to quickly solidify and cool it to ensure the dimensional stability and surface quality of the extruded molded product.

[0003] A cooling device for wires extruded by an extruder with Chinese patent number CN214448390U relates to the technical field of plastic extrusion production. A water tank is arranged on the frame, and one side of the water tank away from the ground is open; a water-draining rack is fixed at the edge of the open side of the water tank; a plurality of rotating shafts are fixed on the water-draining rack, and after the wire passes through the cooling water in the water tank, it passes through multiple groups of guide wheels from low to high along the height direction of the water-draining rack. This application has the effect of less residual moisture in the cooled wire.

[0004] After the existing PVC plastic extrusion strips are extruded, they need to be cooled. There will be some water liquid remaining on the surface of the cooled PVC plastic extrusion strips. If the water liquid is only drained by the water-draining method, it will cause liquid agent residue, which is not conducive to ensuring the drying efficiency of the surface of the PVC plastic extrusion strips.

[0005] Therefore, a water-cooling and water-draining device for PVC plastic extrusion strips is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a water-cooling and water-draining device for PVC plastic extrusion strips to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the present utility model is realized as follows: A water-cooling and water-draining device for a PVC plastic extrusion strip, including a base, the upper end of the base is fixedly connected with a plurality of lifting seats, the plurality of lifting seats are arranged at equal intervals from front to back, the upper end of the lifting seat is fixedly connected with a water-draining ring, the inner end of the water-draining ring is provided with a plurality of water-draining cotton blocks, one end of the plurality of water-draining cotton blocks close to the water-draining ring is fixedly connected with a water-squeezing spring, the end of the water-squeezing spring away from the water-draining cotton block is connected with the inner side wall of the water-draining ring, the lengths of the corresponding plurality of water-squeezing springs are successively decreasing, the outer end of the water-draining ring is fixedly connected with an outer permeable mesh layer, and the inner end of the outer permeable mesh layer is fixedly connected with an electric heating wire mesh.

[0008] Further preferably, an extrusion strip body passes through between the inner ends of the plurality of water-draining rings, and the extrusion strip body cooperates with the water-draining cotton blocks.

[0009] Further preferably, the upper end of the base is fixedly connected with a closed outer frame, and the left end of the base is fixedly connected with a dehumidification pipeline.

[0010] Further preferably, the dehumidification pipeline is externally connected with a dehumidification device, and the dehumidification pipeline is in communication with the closed outer frame.

[0011] Further preferably, through holes are symmetrically opened at the front and rear ends of the closed outer frame, and the outer diameter of the extrusion strip body passes through between the two through holes.

[0012] Further preferably, the front end of the closed outer frame is fixedly connected with an annular electric guide rail, and the annular electric guide rail is located outside the corresponding through hole.

[0013] Further preferably, the output end of the slider is fixedly connected with a slider, and one end of the slider close to the extrusion strip body is fixedly connected with a spring rod.

[0014] Further preferably, one end of the spring rod away from the slider is fixedly connected with a humidity detector, and the humidity detector cooperates with the extrusion strip body.

[0015] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0016] First, in this solution, the extrusion strip body passes through the position between the water-draining rings in the closed outer frame, and the water-draining cotton blocks in the water-draining ring are used to wipe the attached water liquid on the outer wall of the extrusion strip body. The plurality of water-draining cotton blocks make their fit with the outer wall of the extrusion strip body higher through the water-squeezing springs, and the lengths of the corresponding plurality of water-squeezing springs are successively decreasing. This setting method can make the fit degree of the plurality of water-draining cotton blocks with the extrusion strip body increase orderly, make the adsorption effect of the water liquid on the outer wall of the extrusion strip body more uniform, and improve the adsorption ability of the plurality of water-draining cotton blocks for the water liquid.

[0017] Second, during the process of water adsorption outside the extrusion bar body, a closed outer frame can also be set outside the extrusion bar body. The closed outer frame places the water drainage ring in a closed space, and cooperates with the dehumidification equipment connected to the dehumidification pipeline, which is beneficial to quickly discharge the water vapor remaining in the closed outer frame, making the water absorption capacity of the water drainage cotton block stronger and less likely to become saturated. At the same time, it can assist in removing the excess water vapor outside the extrusion bar body. The electric heating wire mesh in the outer permeable net layer outside the water drainage cotton block makes the drying heat source contact the water drainage cotton block, further facilitating the reverse absorption of the water adsorbed in the water drainage cotton block, ensuring the water absorption capacity when the water drainage cotton block contacts the extrusion bar body, and thus ensuring the water drainage efficiency of the extrusion bar body and maintaining the dryness of the extrusion bar body after discharging.

[0018] Third, an annular electric guide rail is also set outside the through hole when the extrusion bar body discharges. The annular electric guide rail can displace annularly outside the extrusion bar body through a slider. When the slider displaces, the humidity detector at its side end continuously contacts the discharged extrusion bar body, and the humidity detector is used to detect the water attachment situation outside the extrusion bar body, avoiding the drawback that the water drainage and drying effect of the extrusion bar body is not good and not being discovered in time.

[0019] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the above-described illustrative aspects, embodiments, and features, by referring to the drawings and the following detailed description, further aspects, embodiments, and features of the present utility model will be readily apparent.

Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0028] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0029] Embodiment 1

[0030] As Figures 1-5 shown, the embodiment of the present invention provides a water-cooling and water-draining device for a PVC plastic extrusion bar, including a base 1. A plurality of lifting seats 5 are fixedly connected to the upper end of the base 1. The plurality of lifting seats 5 are equidistantly arranged from front to back. A water draining ring 4 is fixedly connected to the upper end of the lifting seat 5. A plurality of water draining cotton blocks 6 are arranged at the inner end of the water draining ring 4. One end of the plurality of water draining cotton blocks 6 close to the water draining ring 4 is fixedly connected to a water squeezing spring 10. The end of the water squeezing spring 10 far from the water draining cotton block 6 is connected to the inner side wall of the water draining ring 4. The lengths of the corresponding plurality of water squeezing springs 10 are successively decreasing. The outer end of the water draining ring 4 is fixedly connected to an outer permeable mesh layer 7. An electric heating wire mesh 11 is fixedly connected to the inner end of the outer permeable mesh layer 7.

[0031] An extrusion bar body 8 passes through between the inner ends of the plurality of water draining rings 4. The extrusion bar body 8 cooperates with the water draining cotton blocks 6. A closed outer frame 2 is fixedly connected to the upper end of the base 1. A dehumidifying pipe 9 is fixedly connected to the left end of the base 1. The dehumidifying pipe 9 is externally connected to a dehumidifying device. The dehumidifying pipe 9 is communicated with the closed outer frame 2. Through holes 3 are symmetrically opened at the front and rear ends of the closed outer frame 2. The outer diameter of the extrusion bar body 8 passes through between the two through holes 3.

[0032] Embodiment 2

[0033] In one embodiment, an annular electric guide rail 12 is fixedly connected to the front end of the closed outer frame 2. The annular electric guide rail 12 is located outside the corresponding through hole 3. The output end of a slider 13 is fixedly connected to the slider 13.

[0034] A humidity detector 15 is fixedly connected to one end of the spring rod 14 away from the slider 13, and the humidity detector 15 cooperates with the extrusion bar body 8.

[0035] When the utility model works: In this solution, the extrusion bar body 8 is passed through the position between the water drainage rings 4 in the closed outer frame 2, and the water drainage cotton blocks 6 in the water drainage rings 4 are used to wipe the attached water liquid on the outer wall of the extrusion bar body 8. The multiple water drainage cotton blocks 6 are made to fit the outer wall of the extrusion bar body 8 more closely through the water squeezing springs 10, and the lengths of the corresponding multiple water squeezing springs 10 are arranged in a decreasing order. This setting method can make the fitting degree of the multiple water drainage cotton blocks 6 with the extrusion bar body 8 increase orderly, making the adsorption effect of the water liquid on the outer wall of the extrusion bar body 8 more uniform, improving the adsorption capacity of the multiple water drainage cotton blocks 6 for the water liquid.

The electric heating wire mesh 11 in the outer permeable net layer 7 outside the water drainage cotton blocks 6 is used to make the drying heat source contact the water drainage cotton blocks 6, further facilitating the reverse absorption of the water liquid adsorbed in the water drainage cotton blocks 6, ensuring the water absorption capacity when the water drainage cotton blocks 6 contact the extrusion bar body 8, and thus ensuring the water drainage efficiency for the extrusion bar body 8 and maintaining the dryness of the extrusion bar body 8 after discharging. At the same time, an annular electric guide rail 12 is also arranged outside the through hole 3 when the extrusion bar body 8 discharges. The annular electric guide rail 12 can displace annularly outside the extrusion bar body 8 through the slider 13. When the slider 13 displaces, the humidity detector 15 at its side end continuously contacts the moved-out extrusion bar body 8, and the humidity detector 15 is used to detect the water liquid attachment situation outside the extrusion bar body 8, avoiding the drawback that the water drainage and drying effect of the extrusion bar body 8 is not good and not being discovered in time.
