Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and specifically discloses a raw material screening device for cable production that is easy to replace. Background Technology

[0002] Cables, as a crucial carrier for power transmission and signal communication, play an irreplaceable role in energy, communications, and construction. They possess significant advantages such as high transmission efficiency, excellent insulation, strong anti-interference capabilities, and adaptability to complex environments. They can stably transmit electrical energy or signals over long distances under various operating conditions, making them an indispensable component of modern infrastructure construction and industrial production. In the cable manufacturing process, the purity and particle size of raw materials directly affect the quality of the final product; therefore, raw material screening is necessary.

[0003] Currently, raw material screening is typically performed using vibrating screens. These screens have screens of varying sizes installed inside the machine housing. Vibration causes the raw materials to move on the screens, separating materials of different diameters through the screen openings. However, existing screens are generally fixed to the machine housing by several fasteners. When it's necessary to replace the screens with different sizes to accommodate different raw materials, operators must disassemble each fastener individually. This cumbersome process not only wastes considerable time and manpower but also impacts production efficiency.

[0004] Therefore, a raw material screening device for cable production that is easy to replace is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes a raw material screening device for cable production that is easy to replace. It facilitates the disassembly and replacement of two screen plates, improves the ease of operation, saves time and effort, and thus improves work efficiency.

[0006] This utility model is implemented as follows: a raw material screening device for cable production that is easy to replace includes a base plate and a screening box with a cover on the upper side. The right side wall of the screening box has two vertically distributed discharge outlets. The right side wall of the screening box is fixedly connected to two vertically distributed discharge troughs. The left side wall of the screening box has two insertion interfaces. Each of the two insertion interfaces has a screen plate that extends into the screening box. The two screen plates are respectively attached to the bottom side of the two discharge outlets and the outer wall of the two discharge troughs. A limit mechanism is provided between the screening box and the two screen plates. The limiting mechanism includes limiting sleeves that pass through two screen plates and are fixedly connected to the two screen plates respectively. Each of the two limiting sleeves has a limiting post inserted inside. Each of the two limiting posts has a sliding plate fixedly connected to one side of its opposite side. A compression spring is fixedly connected between the two sliding plates. A dovetail-shaped groove is opened at the left end of the screening box. Each of the two sliding plates has a dovetail-shaped slider fixedly connected to the right end of its right side and slidably connected inside the dovetail-shaped groove. A vibration mechanism is provided on the outside of the screening box.

[0007] As a preferred embodiment of the present invention, a raw material screening device for cable production that is easy to replace, the vibration mechanism includes vibration motors respectively installed at the front and rear ends of the screening box. Multiple support plates are fixedly connected to the lower end of the screening box, and flat plates are fixedly connected to the lower ends of the multiple support plates. Vibration springs are fixedly connected to the four corners of the lower end face of the flat plates, and the other ends of the four vibration springs are fixedly connected to the base plate.

[0008] As a preferred embodiment of the present invention, a raw material screening device for cable production that is easy to replace, wherein the right end of the screening box is provided with a second row of outlets, and the right end of the screening box is fixedly connected to a second row of material troughs.

[0009] As a preferred embodiment of the present invention, a cable production raw material screening device that is easy to replace, each of the two limiting columns has a tapered guide head fixedly connected to one end facing away from the other.

[0010] As a preferred embodiment of the present invention, a raw material screening device for cable production that is easy to replace, a feed hopper is fixedly connected through the upper end of the box cover.

[0011] As a preferred embodiment of the present invention, a raw material screening device for cable production that is easy to replace, wherein the screening box and the two sieve plates are both inclined.

[0012] Preferably, in this utility model, the diameter of the sieve holes on the upper sieve plate is larger than the diameter of the sieve holes on the lower sieve plate, which is an easy-to-replace raw material screening device for cable production.

[0013] The beneficial effects of this utility model are: The screen plate can be removed by pushing the handle of the corresponding sliding plate, causing the dovetail slider to slide within the dovetail groove and compressing the spring. This compresses the spring and pulls the limiting post out of the limiting sleeve, allowing the screen plate to be removed. For installation, the sliding plate needs to be squeezed to compress the spring. After inserting the screen plate into the connector and positioning it, the handle is released to allow the spring to return to its original position, pushing the limiting post into the limiting sleeve for secure installation. This design facilitates the separate removal and replacement of two screen plates, simplifying operation, saving time and effort, and effectively improving work efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-4 A replaceable raw material screening device for cable production includes a base plate 3 and a screening box 1 with a box cover 2 on the upper side. Two vertically distributed discharge outlets 4 are opened through the right side wall of the screening box 1. Two vertically distributed discharge troughs 5 are fixedly connected to the right side wall of the screening box 1. Two insertion interfaces 8 are opened through the left side wall of the screening box 1. Screen plates 9 extending into the interior of the screening box 1 are inserted into the interior of the two insertion interfaces 8. The two screen plates 9 are respectively attached to the bottom side of the interior of the two discharge outlets 4 and the outer wall of the two discharge troughs 5. A limit mechanism is provided between the screening box 1 and the two screen plates 9. The limiting mechanism includes limiting sleeves 10 that pass through two screen plates 9 and are fixedly connected to the two screen plates 9 respectively. Limiting posts 11 are inserted into the interior of each of the two limiting sleeves 10. Sliding plates 12 are fixedly connected to the opposite side of each of the two limiting posts 11. Compression springs 13 are fixedly connected between the two sliding plates 12. A dovetail-shaped groove 14 is opened at the left end of the screening box 1. A dovetail-shaped slider 15 that is slidably connected inside the dovetail-shaped groove 14 is fixedly connected to the right end of each of the two sliding plates 12. A vibration mechanism is installed on the outside of the screening box 1.

[0019] In this embodiment: During operation, the cable production raw materials to be screened are put into the screening box 1. The screening box 1 is driven to vibrate by a vibration mechanism, which in turn drives the two screen plates 9 to vibrate synchronously. The raw materials slide to the right at the upper end of the upper screen plate 9. During the sliding process, the raw materials with a diameter smaller than the screen holes of the upper screen plate 9 pass through the upper screen plate 9 and fall onto the lower screen plate 9; the raw materials with a diameter larger than the screen holes of the upper screen plate 9 slide along the upper screen plate 9 and are discharged through the corresponding discharge outlet 4 and discharge trough 5. The raw materials that fall onto the lower screen plate 9 continue to be screened. The raw materials with a diameter smaller than the screen holes of the lower screen plate 9 pass through the lower screen plate 9 and are finally discharged through the second discharge outlet 6 and the second discharge trough 7; the raw materials with a diameter larger than the screen holes of the lower screen plate 9 slide along the lower screen plate 9 and are discharged through the corresponding discharge outlet 4 and discharge trough 5. When it is necessary to disassemble the upper screen plate 9, since the screen plate 9 is fixed by the limiting mechanism, during operation, push the upper sliding plate 12 downward by the handle at the left end of the upper sliding plate 12. The upper dovetail slider 15 slides downward inside the dovetail groove 14, the compression spring 13 is compressed, and the upper limiting post 11 is pulled out from the upper limiting sleeve 10, releasing the limitation on the upper screen plate 9. At this time, the upper screen plate 9 can be pulled out from the insertion interface 8 to complete the disassembly. When it is necessary to disassemble the lower screen plate 9, push the sliding plate 12 upward by the handle at the left end of the lower sliding plate 12. The dovetail slider 15 slides upward inside the dovetail groove 14, the compression spring 13 is compressed, and the lower limiting post 11 is pulled out from the lower limiting sleeve 10, so that the lower screen plate 9 can be pulled out from the insertion interface 8, and the disassembly is completed. When installing the upper screen plate 9, press down the upper sliding plate 12 to compress the compression spring 13, insert the upper screen plate 9 into the screening box 1 through the upper insertion interface 8, and ensure that the upper screen plate 9 is in contact with the bottom end of the upper discharge outlet 4 and the left end of the discharge chute 5. At this time, the upper limiting post 11 is aligned with the upper limiting sleeve 10. Release the pushing force on the sliding plate 12, the compression spring 13 returns to its original position, and pushes the upper limiting post 11 into the upper limiting sleeve 10. Since the upper insertion interface 8 matches the size of the upper screen plate 9, and the limiting post 11 matches the size of the limiting sleeve 10, the upper screen plate 9 is fixed in place. At this time, the upper screen plate 9 is in contact with the front and rear sides of the inner wall of the screening box 1. The lower screen plate 9 can be fixed in place using the same principle. The above process facilitates the disassembly and replacement of the two sieve plates 9, improving the ease of operation, saving time and effort, and thus improving work efficiency.

[0020] As a technical optimization of this utility model, the vibration mechanism includes vibration motors 20 respectively installed at the front and rear ends of the screening box 1. Multiple support plates 19 are fixedly connected to the lower end of the screening box 1. A flat plate 18 is fixedly connected to the lower end of the multiple support plates 19. Vibration springs 17 are fixedly connected to the four corners of the lower end face of the flat plate 18. The other ends of the four vibration springs 17 are fixedly connected to the base plate 3.

[0021] In this embodiment: the vibration motor 20 in the vibration mechanism is started. Under the flexible support of the four vibration springs 17, the vibration generated by the vibration motor 20 drives the screening box 1 to vibrate, and the screening box 1 in turn drives the two inclined screen plates 9 to vibrate synchronously.

[0022] As a technical optimization of this utility model, a second outlet 6 is provided through the right end of the screening box 1, and a second material trough 7 is fixedly connected to the right end of the screening box 1.

[0023] In this embodiment: the second outlet 6 and the second discharge trough 7 are used to discharge the finest raw material that has passed through the sieve holes after being screened by the lower sieve plate 9.

[0024] As a technical optimization of this utility model, a conical guide head 16 is fixedly connected to one end of each of the two limiting posts 11 that are opposite to each other.

[0025] In this embodiment: when installing the screen plate 9, the tapered guide head 16 at the opposite end of the limiting post 11 can guide the limiting post 11 to be accurately inserted into the limiting sleeve 10, reducing the difficulty of alignment during installation, making the cooperation between the limiting post 11 and the limiting sleeve 10 smoother, and simplifying the fixing operation of the screen plate 9.

[0026] As a technical optimization of this utility model, a feed hopper 21 is fixedly connected through the upper end of the box cover 2.

[0027] In this embodiment: the feed hopper 21 at the top of the cover 2 provides a channel for inputting raw materials, making it easy to introduce the raw materials to be screened into the screening box 1.

[0028] As a technical optimization of this utility model, both the screening box 1 and the two sieve plates 9 are inclined.

[0029] In this embodiment, the inclined arrangement of the screening box 1 and the two screen plates 9, combined with the vibration of the vibration mechanism, causes the raw material to slide along the surface of the screen plate 9 under the dual action of gravity and vibration.

[0030] As a technical optimization of this utility model, the diameter of the sieve hole on the upper sieve plate 9 is larger than the diameter of the sieve hole on the lower sieve plate 9.

[0031] In this embodiment, the diameter of the sieve holes on the upper sieve plate 9 is larger than that on the lower sieve plate 9, thereby achieving graded filtration of raw materials and meeting the requirements of cable production for distinguishing raw materials of different particle sizes.

[0032] The working principle and usage process of this utility model are as follows: During operation, the raw materials for cable production to be screened are fed into the screening box 1 from the feed hopper 21, and the vibration motor 20 in the vibration mechanism is started. Under the flexible support of the four vibration springs 17, the vibration generated by the vibration motor 20 drives the screening box 1 to vibrate, and the screening box 1 in turn drives the two inclined screen plates 9 to vibrate synchronously. The raw materials slide to the right at the upper end of the upper screen plate 9. During the sliding process, the raw materials with a diameter smaller than the screen holes of the upper screen plate 9 pass through the upper screen plate 9 and fall onto the lower screen plate 9; the raw materials with a diameter larger than the screen holes of the upper screen plate 9 slide along the upper screen plate 9 and are discharged through the corresponding discharge outlet 4 and discharge trough 5. The raw materials that fall onto the lower screen plate 9 continue to be screened. The raw materials with a diameter smaller than the screen holes of the lower screen plate 9 pass through the lower screen plate 9 and are finally discharged through the second discharge outlet 6 and the second discharge trough 7; the raw materials with a diameter larger than the screen holes of the lower screen plate 9 slide along the lower screen plate 9 and are discharged through the corresponding discharge outlet 4 and discharge trough 5. When it is necessary to disassemble the upper screen plate 9, since the screen plate 9 is fixed by the limiting mechanism, during operation, push the upper sliding plate 12 downward by the handle at the left end of the upper sliding plate 12. The upper dovetail slider 15 slides downward inside the dovetail groove 14, the compression spring 13 is compressed, and the upper limiting post 11 is pulled out from the upper limiting sleeve 10, releasing the limitation on the upper screen plate 9. At this time, the upper screen plate 9 can be pulled out from the insertion interface 8 to complete the disassembly. When it is necessary to disassemble the lower screen plate 9, push the sliding plate 12 upward by the handle at the left end of the lower sliding plate 12. The dovetail slider 15 slides upward inside the dovetail groove 14, the compression spring 13 is compressed, and the lower limiting post 11 is pulled out from the lower limiting sleeve 10, so that the lower screen plate 9 can be pulled out from the insertion interface 8, and the disassembly is completed. When installing the upper screen plate 9, press down the upper sliding plate 12 to compress the compression spring 13, insert the upper screen plate 9 into the screening box 1 through the upper insertion interface 8, and align the upper screen plate 9 with the bottom end of the upper discharge port 4 and the left end of the discharge chute 5. At this time, the upper limiting post 11 is aligned with the upper limiting sleeve 10. Release the pushing force on the sliding plate 12, the compression spring 13 returns to its original position, and the tapered guide head 16 at the end of the upper limiting post 11 guides the upper limiting post 11 into the upper limiting sleeve 10. Since the upper insertion interface 8 matches the size of the upper screen plate 9, and the limiting post 11 matches the size of the limiting sleeve 10, the upper screen plate 9 is fixed in place. Following the same principle, the lower screen plate 9 can be fixed in place. The above process facilitates the disassembly and replacement of the two sieve plates 9, improving the ease of operation, saving time and effort, and thus improving work efficiency.
