Description

Technical Field

[0001] This utility model relates to the field of low-voltage cable technology, specifically to an extrusion molding equipment for low-voltage cable production. Background Technology

[0002] Cables are conductors covered with insulation, protective layers, and shielding layers used to transmit electrical or signal current and voltage. They can be classified into high-voltage cables and low-voltage cables according to voltage. Although low-voltage cable lines are more expensive and more difficult to lay and maintain compared to low-voltage overhead lines and low-voltage insulated overhead lines, they are widely used in low-voltage power distribution systems due to their reliable operation, lack of poles, lack of ground occupation, unobstructed appearance, and less susceptibility to external influences. During the production process, low-voltage cables require extrusion molding equipment to fabricate their insulation or sheath.

[0003] When using some existing extrusion molding equipment, some damp or fine powdery raw materials may stick to the inner wall of the raw material barrel during the extrusion molding process. Over time, this affects the raw material feeding efficiency and requires the equipment to be shut down for cleaning of the raw material barrel, thus reducing the working efficiency of the extrusion molding equipment. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion molding equipment for low-voltage cable production, so as to solve the problem that some damp or fine powdery raw materials adhere to the inner wall of the raw material barrel, affecting the efficiency of raw material conveying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion molding equipment for low-voltage cable production, comprising an extrusion molding equipment body, and further comprising:

[0006] A support plate is installed at the bottom of the extrusion molding equipment body. The top of the extrusion molding equipment body is connected to a raw material barrel, and the top of the raw material barrel is connected to a feed cylinder.

[0007] A cleaning assembly is installed on the top of the raw material barrel. The cleaning assembly includes a transmission box fixedly connected to the top of the raw material barrel. A transmission rod is rotatably connected to the top of the inner cavity of the transmission box. A rotating rod is fixedly connected to the bottom of the transmission rod. A stirring roller is fixedly connected to the outer side of the rotating rod. A scraper is provided at the end of the stirring roller away from the rotating rod.

[0008] Preferably, a first crushing plate is fixedly connected to the outer side of the rotating rod, and a second crushing plate is fixedly connected to the outer side of the rotating rod.

[0009] Preferably, a transmission seat is fixedly connected to the end of the stirring roller away from the rotating rod, and a rotating ball is fixedly connected inside the transmission seat.

[0010] Preferably, the outer side of the rotating ball is rotatably connected to the inside of the scraper, and a motor is fixedly connected to the top of the inner cavity of the transmission box.

[0011] Preferably, the output end of the motor is fixedly connected to a base rod, and a first gear is fixedly connected to the outer side of the base rod.

[0012] Preferably, the outer side of the first gear is meshed with a second gear, and the inner ring of the second gear is fixedly connected to the outer side of the transmission rod.

[0013] Preferably, a fixing frame is fixedly connected to the inner wall of the raw material barrel, a filter screen is provided on the inner wall of the raw material barrel, a horizontal bar is fixedly connected to the outer side of the rotating rod, and a rubber plate is fixedly connected to the bottom of the horizontal bar.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a cleaning component. Raw materials enter the material barrel through the feed cylinder and then into the extrusion molding equipment for extrusion molding. Some raw materials adhere to the inner wall of the material barrel. Starting the motor causes the rotating rollers to rotate via the first and second gears. These rollers are connected to a scraper via a transmission seat and a rotating ball. As the rollers rotate, the outer side of the scraper fits tightly against the inner wall of the material barrel, allowing the material adhering to the inner wall to detach. Simultaneously, the rotation of the rotating rod drives two horizontal bars to rotate, causing the rubber plate to move and clean the material on top of the filter screen, allowing materials of the correct size to pass through the filter.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-5 As shown, an extrusion molding equipment for low-voltage cable production includes an extrusion molding equipment body 1. The extrusion molding equipment body 1 includes a screw, a barrel, a hopper, a die head, and a mold. Plastic is squeezed forward by the screw rotating in the heated barrel, and after being uniformly plasticized, it is extruded and molded through the die head and mold. The equipment also includes:

[0024] The support plate 2 is set at the bottom of the extrusion molding equipment body 1. By setting the support plate 2, the extrusion molding equipment body 1 can be supported and placed, so that the extrusion molding equipment body 1 can be placed stably. The top of the extrusion molding equipment body 1 is connected to the raw material tank 3. By setting the raw material tank 3, the raw material can be stirred and mixed. The top of the raw material tank 3 is connected to the feed cylinder 4. By setting the feed cylinder 4, the raw material can be easily conveyed by the operator under the action of two feed cylinders 4, so that the raw material can enter the interior of the raw material tank 3.

[0025] The cleaning component 5, located at the top of the raw material drum 3, scrapes off the raw material adhering to the inner wall of the drum 3, allowing it to detach and reducing resource waste. The cleaning component 5 includes a transmission box 51 fixedly connected to the top of the raw material drum 3. The transmission box 51 ensures stability of the motor 10 and transmission rod 52 during normal operation. The transmission rod 52 is rotatably connected to the top of the inner cavity of the transmission box 51. When the transmission rod 52 rotates, it drives a rotating rod 53 to rotate. The rotating rod 53 is fixedly connected to the bottom of the transmission rod 52. When the rotating rod 53 rotates... Under the action of the rotating rod 53, multiple stirring rollers 54 on its outer side can be driven to rotate, thereby mixing the raw materials inside the raw material barrel 3. The stirring rollers 54 are fixedly connected to the outer side of the rotating rod 53. By setting the stirring rollers 54, the inside of the stirring rollers 54 is hollow, which can prevent the raw materials from falling onto the top of the stirring rollers 54. At the same time, the stirring rollers 54 at multiple positions can make the raw materials inside the raw material barrel 3 fully mixed. A scraper 55 is set at the end of the stirring roller 54 away from the rotating rod 53. By setting multiple scrapers 55, the angle between the scraper 55 and the raw material barrel 3 can be adjusted by the rotating ball 8, so that the outer side of the scraper 55 is in contact with the inner wall of the raw material barrel 3, thereby making the raw materials more evenly mixed.

[0026] refer to Figure 2 and Figure 3 As shown, a first crushing plate 6 is fixedly connected to the outer side of the rotating rod 53, and a second crushing plate 7 is fixedly connected to the outer side of the rotating rod 53. By setting the first crushing plate 6 and the second crushing plate 7, the first crushing plate 6 and the second crushing plate 7 are located at different heights on the same vertical line, and multiple crushing plates are placed crosswise, so that some of the agglomerated raw materials can be fully broken up.

[0027] A transmission seat 9 is fixedly connected to the end of the stirring roller 54 away from the rotating rod 53. By setting the transmission seat 9, the rotating ball 8 can be placed under the action of the transmission seat 9. The rotating ball 8 is fixedly connected inside the transmission seat 9. By setting the rotating ball 8, the outer side of the rotating ball 8 is rotatably connected to the inside of the scraper 55. During the continuous movement of the scraper 55, a part of the outer side of the scraper 55 can be made to adhere to the inner wall of the raw material barrel 3, thereby allowing the raw material attached to the inner wall of the raw material barrel 3 to be detached.

[0028] The outer side of the rotating ball 8 is rotatably connected to the inside of the scraper 55. The top of the inner cavity of the transmission box 51 is fixedly connected to the motor 10. By setting the motor 10, the rotation of the rotating rod 53 can be powered by the motor 10.

[0029] refer to Figure 4 and Figure 5As shown, a base rod 11 is fixedly connected to the output end of the motor 10, and a first gear 12 is fixedly connected to the outside of the base rod 11. By setting the base rod 11 and the first gear 12, the first gear 12 and the second gear 13 are of different sizes, so the speed of the second gear 13 can be adjusted by the speed of the first gear 12.

[0030] The outer side of the first gear 12 is meshed with the second gear 13. The inner ring of the second gear 13 is fixedly connected to the outer side of the transmission rod 52. By setting the second gear 13 and the transmission rod 52, when the second gear 13 rotates, it can drive the transmission rod 52 to rotate.

[0031] A fixing frame 14 is fixedly connected to the inner wall of the raw material barrel 3. A filter screen 15 is provided on the inner wall of the raw material barrel 3. By setting the filter screen 15, raw materials that do not meet the size requirements can be filtered. A horizontal bar 16 is fixedly connected to the outer side of the rotating rod 53. A rubber plate 17 is fixedly connected to the bottom of the horizontal bar 16. By rotating the horizontal bar 16, it can drive the rubber plate 17 to rotate. Then, the rubber plate 17 can squeeze part of the raw material at the top of the filter screen 15, so that some raw materials that meet the size requirements can pass through the filter screen 15.

[0032] Working principle: When workers use this device to produce insulation or sheathing for low-voltage cables, some raw materials may adhere to the inner wall of the raw material barrel 3. Workers can start the motor 10, which drives the bottom rod 11 to rotate. This, in turn, causes the transmission rod 52 and the rotating rod 53 to rotate through the rotation of the first gear 12 and the second gear 13. When the rotating rod 53 rotates, it drives multiple stirring rollers 54 to rotate. The multiple cross-placed stirring rollers 54 and scrapers 55 can thoroughly clean the inner wall of the raw material barrel 3. At the same time, when the scrapers 55 rotate under the action of the stirring rollers 54, the angle between the scrapers 55 and the raw material barrel 3 changes. Under the action of the rotating ball 8, the angle of the scrapers 55 can be adjusted, allowing the scrapers 55 to clean the raw materials adhering to the inner wall of the raw material barrel 3, causing the raw materials to detach from the inner wall of the raw material barrel 3.
