Description

Technical Field

[0001] This utility model relates to the field of cable material manufacturing technology, and more specifically, to an air-cooled vibrating bed for PVC cable material granules. Background Technology

[0002] The PVC cable material granule air-cooled vibrating bed is a device specifically designed for the post-processing of PVC (polyvinyl chloride) cable material granules. Its core purpose is to achieve rapid cooling, uniform grading, and efficient output of the granules through a combination of vibration dispersion and forced air cooling.

[0003] The existing publicly available technology, application number CN201921824083.0, describes a cooling and grading device for granular cable materials. This device can effectively cool, remove dust, and separate significantly different particles from granular cable materials using a single set of equipment. Its structure is not complex and it is a technical modification suitable for implementation on the production site.

[0004] Based on the aforementioned patents and the current situation, it is not difficult to find that the traditional air ducts used for cooling on existing air-cooled vibrating beds adopt a single-sided air intake or a simple straight-through design, resulting in uneven airflow distribution, poor cooling effect in local areas of the bed surface, and the formation of "hot and cold dead zones." This easily leads to uneven particle cooling, increased risk of agglomeration, and energy waste. Moreover, the screen is fixed with bolts or embedded in a groove, and replacement requires disassembling multiple parts, which is time-consuming and can easily cause screen deformation, resulting in long downtime, high maintenance costs, and overall less than ideal performance.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an air-cooled vibrating bed for PVC cable material granules, which has the advantages of convenient maintenance, good cooling effect, and wide applicability, thereby solving the problems mentioned in the background technology.

[0007] To achieve the aforementioned advantages of convenient maintenance, good cooling effect, and wide applicability, the specific technical solution adopted by this utility model is as follows:

[0008] A PVC cable material granule air-cooled vibrating bed includes a vibrating bed body and support legs. Cooling strips are symmetrically installed on both sides of the inner surface of the vibrating bed body. An air distribution plate is installed at the air outlet of the cooling strip. Several sets of adjusting shafts are rotatably connected to one side of the air distribution plate inside the cooling strip. Guide vanes are installed on the surface of the adjusting shaft. One end of the adjusting shaft passes through one side of the surface of the vibrating bed body, and several sets of positioning holes are opened at the end of the adjusting shaft. The positioning holes are fixed to the surface of the vibrating bed body by bolts. Several sets of air outlets are evenly arranged on one side of the adjusting shaft inside the cooling strip. One end of the air outlet is connected to an air supply box through a pipe. The air supply box is connected to an external fan through an air supply pipe.

[0009] Furthermore, several sets of support bars are uniformly welded to the bottom surface of the inner side of the vibrating bed body, and screen plates are slidably connected between each pair of support bars.

[0010] Furthermore, a handle is fixedly installed at the middle position of one end surface of the screen plate.

[0011] Furthermore, several sets of adjustment grooves are symmetrically and evenly opened on both sides of the handle on the surface of the screen plate. A pressure plate is slidably connected inside the adjustment groove. A limit post is fixedly installed in the middle of the surface of the pressure plate. One end of the limit post penetrates one side of the screen plate. A spring is sleeved on the outer periphery of the limit post inside the adjustment groove.

[0012] Furthermore, fixing plates are symmetrically welded to the four sides of the vibrating bed body.

[0013] Furthermore, a support leg is fixedly installed at the bottom of the fixing plate.

[0014] Furthermore, a threaded hole is provided on one side of the adjustment shaft at a position corresponding to the surface of the vibrating bed body.

[0015] Furthermore, a vibration motor is installed on one side of the bottom of the vibrating bed body.

[0016] Compared with the prior art, the present invention provides an air-cooled vibrating bed for PVC cable material granules, which has the following beneficial effects:

[0017] (1) This utility model adopts cooling strips, air distribution plates and guide vanes. During operation, while vibrating, the cooling strips on both sides can spray cold air evenly through the air distribution plates, so that the gas can act more evenly on the cable material particles, improving the air cooling effect. Moreover, the single-sided air duct is changed to a symmetrical double air duct with air intake on both sides to eliminate airflow dead angles. In addition, an air distribution plate is added to the air duct outlet to force the airflow to be evenly distributed. At the same time, an adjustable guide vane is added in the air duct. By manually adjusting the vane angle to adapt to the thickness of different particle layers, the overall airflow uniformity and cooling efficiency are improved, making it easier to use. It has the advantages of good cooling effect and wide applicability.

[0018] (2) This utility model adopts a pressure plate and a limiting column. During operation, the screen plate used for vibrating screening adopts a detachable structure, which is convenient for later maintenance. When maintenance is required, the pressure plate only needs to be pressed to drive the spring to compress and then the limiting column moves down as a whole. At this time, the screen plate can be separated from the surface of the vibrating bed. Then, the personnel can quickly unload the screen plate by using the handle, which is convenient for subsequent maintenance or replacement, reduces downtime during maintenance, improves maintenance efficiency, and is easier to use. It has the advantage of convenient maintenance. Attached Figure Description

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, an air-cooled vibrating bed for PVC cable material granules is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, the PVC cable material granule air-cooled vibrating bed according to an embodiment of the present invention includes a vibrating bed body 1 and support legs 13. Cooling strips 8 are symmetrically installed on both sides of the inner surface of the vibrating bed body 1. An air distribution plate 7 is installed at the air outlet of the cooling strips 8. Several sets of adjusting shafts 5 are rotatably connected to one side of the air distribution plate 7 inside the cooling strips 8. Guide vanes 6 are installed on the surface of the adjusting shafts 5. One end of the adjusting shaft 5 passes through one side of the surface of the vibrating bed body 1, and several sets of positioning holes 19 are opened at the end of the adjusting shaft 5. The positioning holes 19 are fixed to the surface of the vibrating bed body 1 by bolts. Several sets of air outlets 4 are evenly arranged on one side of the adjusting shaft 5 inside the cooling strips 8. One end of the air outlet 4 is connected to the air supply box 2 through a pipe. The air supply box 2 is connected to an external fan through an air supply pipe 3.

[0028] In one embodiment, several sets of support bars 11 are uniformly welded to the bottom surface of the vibrating bed body 1. A screen plate 9 is slidably connected between each pair of support bars 11. The support bars 11 are designed to support the screen plate 9. The surface of the support bars 11 is provided with grooves to facilitate the sliding insertion of the screen plate 9. The edge of the screen plate 9 can be provided with a silicone sealing strip to prevent particle leakage and eliminate the need for bolt fixing.

[0029] In one embodiment, a handle 15 is fixedly installed at the middle position of one end surface of the screen plate 9. The handle 15 is provided to facilitate the operation and use of the screen plate 9 by personnel and improve the ease of use.

[0030] In one embodiment, several sets of adjustment grooves 14 are symmetrically and evenly provided on both sides of the handle 15 on the surface of the screen plate 9. A pressure plate 17 is slidably connected inside the adjustment groove 14. A limit post 16 is fixedly installed in the middle of the surface of the pressure plate 17. One end of the limit post 16 penetrates one side of the screen plate 9. A spring 18 is sleeved on the outer periphery of the limit post 16 inside the adjustment groove 14. The limit post 16 is provided to facilitate the insertion and fixing of the screen plate 9, thereby facilitating subsequent maintenance and use. Therefore, due to the setting of the limit post 16 and the structural setting of the end of the screen plate 9, the position where the surface of the vibrating bed body 1 contacts the screen plate 9 needs to have corresponding grooves and openings to facilitate the installation and fixing of the screen plate 9. Since the above structure is relatively mature in daily use, it will not be described in detail.

[0031] In one embodiment, fixing plates 12 are symmetrically welded to the four sides of the vibrating bed body 1. The fixing plates 12 are provided to facilitate the installation and use of the support legs 13.

[0032] In one embodiment, a support leg 13 is fixedly installed at the bottom of the fixing plate 12, and the device can be fixed by the support leg 13.

[0033] In one embodiment, a threaded hole is provided on one side of the adjusting shaft 5 on the surface of the vibrating bed body 1. The threaded hole is provided to facilitate locking the adjusting shaft 5 after adjustment, thereby changing the tilt angle of the guide vanes 6 on its surface, thus guiding the gas to different positions, and then performing air cooling operation on particles of different sizes, expanding the applicability of the structure and facilitating better use.

[0034] In one embodiment, a vibration motor 10 is installed on one side of the bottom of the vibrating bed body 1. The vibration motor 10 is provided to provide the vibration force required for the operation of the vibrating bed. Since the vibration motor 10 is of various types and the application technology is mature, personnel can flexibly select the appropriate model and install it in the appropriate position. This will not be elaborated on further here.

[0035] Working Principle: In actual use, personnel can feed the PVC cable material granules requiring air-cooled vibrating screening onto the vibrating bed body 1. Then, the vibration motor 10 located on the bottom side of the vibrating bed body 1 transmits vibration to the screen plate 9, which in turn transmits the vibration to the cable material granules, thus achieving the vibrating screening operation. Simultaneously, cooling air is evenly sprayed out through the air distribution plate 7 via the cooling strips 8 on both sides, ensuring more uniform airflow onto the cable material granules and improving the air-cooling effect. Furthermore, the structure changes from a single-sided air duct to a symmetrical double air duct, with opposing air intakes on both sides, eliminating dead airflow angles. The air distribution plate 7 is also installed at the air duct outlet to force uniform airflow distribution. Adjustable guide vanes 6 are added inside the air duct. By manually adjusting the vane angle, they can adapt to the thickness of different particle layers, thereby improving the overall airflow uniformity and cooling efficiency, making it easier to use. In addition, the screen plate 9 used for vibrating screening adopts a detachable structure, which facilitates later maintenance. When maintenance is required, simply press the pressure plate 17 to drive the spring 18 to compress, which will cause the limiting column 16 to move down. At this time, the screen plate 9 can be separated from the surface of the vibrating bed. Then, the personnel can quickly unload the screen plate 9 through the handle 15, which facilitates subsequent maintenance or replacement, reduces downtime during maintenance, improves maintenance efficiency, and facilitates better use. The device as a whole has the advantages of convenient maintenance, good cooling effect, and wide applicability.
