Description

Technical Field

[0001] This utility model relates to the field of rubber extruder technology, specifically to a multi-channel automatic feeding device for rubber extruders. Background Technology

[0002] A rubber extruder is an industrial extruder used to extrude rubber semi-finished or finished products of various cross-sectional shapes. It is mainly used in the production of rubber strips and sheets for wires and cables. A rubber extruder mainly consists of a screw, barrel, die head, feeding device, automatic feeding device, temperature control system, and electrical control device. When using a rubber extruder, a feeding device is required to deliver the rubber material into the extruder. However, the feeding devices of existing rubber extruders cannot control the feeding speed of the rubber material, which affects the efficiency of subsequent screw crushing of the rubber material. At the same time, most of the existing feeding devices are single-channel feeding devices, which reduces the practicality of the device.

[0003] For example, a rubber extruder feeding mechanism described in patent CN221339485U includes a placement block; the top wall of the placement block has a first feeding groove; a first push plate is slidably connected to the side wall of the first feeding groove, which is driven by a hydraulic telescopic rod through a pushing assembly to move the first push plate along the first feeding groove, introducing the raw material in the first feeding groove from the first discharge port into the heating system of the extruder. Because the four sides of the first push plate are in contact with the first feeding groove, it can effectively prevent the rubber raw material from adhering to the side wall surface of the first feeding groove, thus avoiding the problem of rubber adhering to the inner wall of the container or pipe, resulting in discontinuous feeding and affecting production efficiency. However, when feeding the extruder, it cannot control the feeding speed of the rubber material, affecting the efficiency of subsequent screw crushing of the rubber material. At the same time, when feeding the extruder, it can only feed from one feeding channel at a time, reducing the feeding speed. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4As shown, a multi-channel automatic feeding device for a rubber extruder includes a first feeding channel 1, a second feeding channel 11 at the upper end of the first feeding channel 1, a discharge port on the left side of the first feeding channel 1 connected to the extruder, a baffle 12 fixedly connected to the top near the discharge port, a conveyor belt 14 in the inner cavity of both the first feeding channel 1 and the second feeding channel 11, a guide roller 13 rotatably connected to the inner wall of the first feeding channel 1 and the second feeding channel 11 near the conveyor belt 14, a connecting frame 16 fixedly connected to the right side of both the first feeding channel 1 and the second feeding channel 11, a feed guide roller 17 rotatably connected to the outer wall of the connecting frame 16, a motor 18 fixedly connected to the rear end of both the first feeding channel 1 and the second feeding channel 11, a feeding roller 19 fixedly connected to the outer wall of the motor 18, a monitoring mechanism 2 on the outer wall of both the first feeding channel 1 and the second feeding channel 11, and an auxiliary mechanism 3 on the outer wall of both the first feeding channel 1 and the second feeding channel 11 near the monitoring mechanism 2.

[0025] In this embodiment, automatic feeding can be achieved by using motor 18 and feeding roller 19 in conjunction with auxiliary mechanism 3, which also makes the feeding more stable and prevents the rubber strip from falling off. During the feeding process, monitoring mechanism 2 monitors the stroke of feeding roller 19 to determine the amount of feed and achieve the effect of controlling the feeding.

[0026] In an optional embodiment, such as Figures 1-3 As shown, a guide plate 15 is fixedly connected to the left side of the second feeding channel 11, and the guide plate 15 is located directly above the discharge port. The guide plate 15 guides the rubber strip so that it can fall into the discharge port of the first feeding channel 1.

[0027] In an optional embodiment, such as Figures 1-3 As shown, the width of the guide plate 15 is less than the distance between the two guide rollers 13, and the guide plate 15 has a certain inclination, so that the guide plate 15 can be located between the two guide rollers 13, allowing the rubber strip to accurately enter the discharge port.

[0028] In an optional embodiment, such as Figures 1-3 As shown, the monitoring mechanism 2 includes a fixed plate 21. The outer wall of the fixed plate 21 is fixedly connected to the outer wall of the second feeding channel 11 by bolts. A monitoring instrument 22 is fixedly connected to the inner wall of the fixed plate 21. The monitoring head of the monitoring instrument 22 is close to the outer wall of the feeding roller 19. During the feeding process, the monitoring instrument 22 monitors the stroke of the feeding roller 19 to determine the feeding amount. When the feeding amount reaches the preset threshold, the motor 18, the conveyor belt 14 and the motor 38 stop operating, thus achieving the effect of quantitative feeding.

[0029] In an optional embodiment, such as Figure 2 and Figure 3As shown, the monitor 22, motor 18 and conveyor belt 14 are electrically connected. When the monitor 22 detects that the stroke of the feeding roller 19 reaches the preset threshold, it can feed the information back to the control center, so that the feeding roller 19 and the conveyor belt 14 stop running.

[0030] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the auxiliary mechanism 3 includes a second motor 31. The output end of the second motor 31 is rotatably connected to the outer wall of the second feeding channel 11. A mounting bracket 32 ​​is fixedly connected to the outer wall of the output end of the second motor 31. The mounting bracket 32 ​​is rotatably connected to the outer wall of the output end of the first motor 18 near its inner wall. The mounting bracket 32 ​​is rotatably connected to the outer wall of the second feeding channel 11 near its outer wall. A telescopic rod 33 is fixedly connected to the top of the mounting bracket 32. A mounting plate 35 is fixedly connected to the movable rod of the telescopic rod 33 through the outer wall of the mounting bracket 32. A spring 34 is sleeved on the outer wall of the telescopic rod 33, with one end of the spring 34 abutting against the mounting bracket 32 ​​and the other end abutting against the mounting plate 35. A connecting plate 37 is fixedly connected to the bottom of the mounting plate 35. A third motor 38 is fixedly connected to the inner wall of the connecting plate 37. The output end of the third motor 38 is fixedly connected to... With gear 39 attached, one end of the rubber strip is placed between the feeding roller 19 and gear 39. The gear 39 and feeding roller 19 drive the rubber strip. During the transmission process, the connecting plate 37 drives the mounting plate 35 to move upward, causing the spring 34 and telescopic rod 33 to retract. At the same time, the elastic force of the spring 34 ensures the downward pressure of gear 39, so that gear 39 and feeding roller 19 can squeeze the rubber strip tightly enough to prevent the rubber strip from falling off. After the rubber strip falls onto the conveyor belt 14, motor 31 is started, driving the mounting frame 32 to rotate, so that the angle between the mounting frame 32 and the second feeding channel 11 is a right angle. At the same time, the mounting frame 32 drives gear 39 to rotate synchronously, thereby changing the driving direction of the feeding roller 19 and gear 39 on the rubber strip, so that the rubber strip can fit more closely to the conveyor belt 14, making the transportation process more stable.

[0031] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the width of gear 39 is smaller than the distance between the two feed guide rollers 17, so that gear 39 will not be dry with feed roller 19 when conveying rubber strip.

[0032] In an optional embodiment, such as Figure 3 and Figure 4 As shown, a guide block 36 is fixedly connected to the outer wall of the mounting plate 35. The outer wall of the guide block 36 is slidably connected to the groove opened on the inner side of the mounting frame 32. The guide block 36 limits and guides the mounting plate 35 so that the mounting plate 35 will not deviate when it moves.

[0033] The above embodiments disclose a multi-channel automatic feeding device for a rubber extruder. When feeding is required, motor 18 and motor 38 are started in opposite directions. One end of the rubber strip is then placed between the feeding roller 19 and the gear 39. The gear 39 and the feeding roller 19 drive the rubber strip. During this transmission, the connecting plate 37 drives the mounting plate 35 upwards, causing the spring 34 and the telescopic rod 33 to contract. Simultaneously, the elastic force of the spring 34 ensures the downward pressure of the gear 39, allowing the gear 39 and the feeding roller 19 to... The rubber strip is compressed tightly enough to prevent it from falling off, thus moving it onto the conveyor belt 14. During this movement, the feed guide rollers 17 and 13 limit the rubber strip to prevent it from falling off. Once the rubber strip falls onto the conveyor belt 14, the second motor 31 is started, driving the mounting frame 32 to rotate, making the angle between the mounting frame 32 and the second feeding channel 11 a right angle. Simultaneously, the mounting frame 32 drives the gear 39 to rotate synchronously, thereby changing the driving direction of the feed rollers 19 and gear 39 on the rubber strip. Subsequently... The rubber strip located in the second feeding channel 11 moves to the guide plate 15, where it is guided to fall into the discharge port of the first feeding channel 1. During the fall, the baffle 12 and the guide roller 13 on the first feeding channel 1 prevent the rubber strip from deviating and falling outside the discharge port. Simultaneously, the rubber strip on the second feeding channel 11 is prevented from interfering with the feeding of the rubber strip on the first feeding channel 1, thus allowing simultaneous feeding through both channels. During the process, the monitoring instrument 22 monitors the stroke of the feeding roller 19 to determine the feeding amount. When the feeding amount reaches the preset threshold, the motor 18, the conveyor belt 14, and the motor 38 stop operating, thus achieving the effect of quantitative feeding. In summary, automatic feeding can be achieved by using the motor 18 and the feeding roller 19 in conjunction with the auxiliary mechanism 3, while making the feeding more stable and preventing the rubber strip from falling off. During the feeding process, the monitoring mechanism 2 monitors the stroke of the feeding roller 19 to determine the feeding amount, thereby achieving the effect of controlling the feeding.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
