Description

Technical Field

[0001] The present application relates to the technical field of extruder feeding, and in particular to a multi-group feeding collection and conveying device. Background Art

[0002] In the research and development of low-smoke halogen-free flame-retardant thermoplastic elastomer FR-TPE, the product formula includes a variety of raw materials, including a variety of base plastic resin particles, a variety of flame retardant combinations, a variety of elastomer components, a variety of anti-aging / scratch resistant additives, etc., mainly particles and powders.

[0003] And the raw material ratio of the product is particularly important, so the raw materials must first be weighed and measured, and then the weighed raw materials are mixed and processed.

[0004] Normally, a loss-in-weight scale is required for weighing and metering raw materials. After being weighed and metered by the loss-in-weight scale, the raw materials enter the feeding port of the extruder. It should be noted that a loss-in-weight scale can only weigh and meter a single raw material. Since the product is mixed with multiple raw materials according to the formula ratio, multiple loss-in-weight scales must be set up in this case to weigh and meter the raw materials. However, the area at the feeding port of the extruder is small and the loss-in-weight scale itself is large, so it is impossible to place and install multiple loss-in-weight scales. Utility Model Content

[0005] In order to improve the above-mentioned problems in the prior art, the present application provides a multi-group feeding collection and conveying device.

[0006] The present application provides a multi-group feeding collection and conveying device, which adopts the following technical solution:

[0007] A multi-group feeding and collecting conveying device comprises an auger conveyor, wherein the auger conveyor is arranged above an extruder, a placing rack is set above the extruder, the auger conveyor is installed and fixed on the placing rack, the spiral blades on the transmission shaft inside the auger conveyor are divided into two sections with the midpoint of the transmission shaft as the center, and the rotation directions of the two sections of the spiral blades are opposite, an auger discharge port is set on the side of the auger conveyor close to the extruder, the auger discharge port is located at the midpoint of the transmission shaft, the auger discharge port is connected with the feeding port of the extruder, a plurality of loss-in-weight scales are set above the auger conveyor, the plurality of loss-in-weight scales are distributed along the length direction of the auger conveyor, and are distributed on both sides of the midpoint of the transmission shaft, and the discharge port of the loss-in-weight scale is connected with the feeding port of the auger conveyor.

[0008] By adopting the above technical solution, after the loss-in-weight scale completes the weighing and metering of the raw materials, the raw materials are transported into the auger conveyor. The rotation of the transmission shaft drives the two spiral blades with opposite rotation directions to rotate, which can transport the raw materials on both sides of the auger conveyor to the middle, so that the raw materials enter the feeding port through the auger discharge port. It should be emphasized that the auger conveyor is installed and fixed on the placement rack, so that the loss-in-weight scale can be set up on the auger conveyor by relying on the placement rack, and the loss-in-weight scale is distributed along the length direction of the auger conveyor, so multiple loss-in-weight scales can be set up, thereby solving the problem that multiple loss-in-weight scales cannot be placed and installed.

[0009] Optionally, the loss-in-weight scales are distributed on both sides of the auger conveyor in the width direction, and the discharge ports of the loss-in-weight scales are inclined toward the auger conveyor and connected to the feed port of the auger conveyor.

[0010] By adopting the above technical solution, the loss-in-weight scales are distributed on both sides of the width direction of the auger conveyor. Compared with distributing the loss-in-weight scales along the length direction of the auger conveyor, it is more intensive and space-saving, and can also ensure that the weighed and metered raw materials are smoothly transported to the auger conveyor.

[0011] Optionally, the loss-in-weight scale includes a particle loss-in-weight scale and a powder loss-in-weight scale, the particle loss-in-weight scale is distributed on both sides of the midpoint of the transmission shaft, and the powder loss-in-weight scale is arranged at the midpoint of the transmission shaft.

[0012] By adopting the above technical scheme, the particle loss-in-weight scale can weigh and measure the particle raw materials, and the powder loss-in-weight scale can weigh and measure the powder raw materials. The particle loss-in-weight scales are distributed on both sides of the midpoint of the transmission shaft, and the powder loss-in-weight scale is set at the midpoint of the transmission shaft. Then, during the operation of the auger conveyor, the particle raw materials on both sides can drive the powder raw materials in the middle to be discharged from the auger discharge port, thereby ensuring that the powder raw materials will not remain in the auger conveyor, thereby improving the feeding effect of the auger conveyor.

[0013] Optionally, a connecting pipe is fixedly connected to the auger discharge port, and the connecting pipe passes downward through the placement rack and extends into the feeding port.

[0014] By adopting the above technical scheme, the raw materials are discharged from the auger discharge port and enter the connecting pipe. The connecting pipe can not only guide the raw materials to be transported to the feeding port, but also prevent the raw materials, especially the powdered raw materials, from drifting into the external environment during the process from the auger discharge port to the feeding port, thereby avoiding the waste of raw materials and further improving the feeding effect of the auger conveyor to the extruder.

[0015] Optionally, the connecting pipe and the auger outlet are connected by a flange.

[0016] By adopting the above technical solution, the connecting pipe is flange-connected to the auger outlet, so that the connecting pipe can be disassembled to facilitate regular cleaning of the raw materials remaining inside the connecting pipe to ensure that feeding to the extruder can proceed normally.

[0017] Optionally, a dust shield is provided along the circumferential direction on the outer wall of one end of the connecting pipe extending into the feeding port, the dust shield covers the feeding port, and the end of the dust shield away from the connecting pipe hangs down along the outer wall of the feeding port.

[0018] By adopting the above technical solution, the dust shield cloth can cover the feeding end of the feeding port without affecting the feeding of the connecting pipe to the feeding port, thereby preventing foreign matter in the external environment from entering the feeding port and preventing the powder raw materials from floating outward into the external environment.

[0019] Optionally, one end of the dust shield cloth close to the connecting pipe is connected and fixed with a rubber band along the circumferential direction, and the dust shield cloth is tightened and fixed to the connecting pipe by the rubber band.

[0020] By adopting the above technical solution, the dust shield cloth can be tightened and fixed on the connecting pipe by relying on the elasticity of the rubber band rope, and the dust shield cloth can also be removed from the connecting pipe manually, so that the dust shield cloth will not fall off from the connecting pipe spontaneously, thereby ensuring the dust blocking effect of the dust shield cloth.

[0021] Optionally, an observation mirror is provided on the side wall of the feeding port of the extruder.

[0022] By adopting the above technical solution, workers can observe the feeding situation inside the feeding port through the viewing mirror.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. After the loss-in-weight scale completes the weighing and metering of the raw materials, the raw materials are transported into the auger conveyor. The rotation of the transmission shaft drives the two spiral blades with opposite rotation directions to rotate, which can transport the raw materials on both sides of the auger conveyor to the middle, so that the raw materials enter the feeding port through the auger discharge port. It should be emphasized that the auger conveyor is installed and fixed on the placement rack, so that the loss-in-weight scale can be set up on the auger conveyor with the help of the placement rack, and the loss-in-weight scale is distributed along the length direction of the auger conveyor, so multiple loss-in-weight scales can be set up, thus solving the problem that multiple loss-in-weight scales cannot be placed and installed.

[0025] 2. Distributing the loss-in-weight scales on both sides of the auger conveyor in the width direction is more intensive and space-saving than distributing all the loss-in-weight scales along the length direction of the auger conveyor. It can also ensure that the weighed raw materials can be smoothly transported to the auger conveyor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a multi-group feeding collection and conveying device, referring to Figure 1 The multi-group feeding and conveying device includes an auger conveyor 1, a placement rack 3 is set above the extruder 2, and the auger conveyor 1 is installed and fixed on the placement rack 3, that is, the auger conveyor 1 is located directly above the extruder 2. There is only one transmission shaft inside the auger conveyor 1, and the spiral blades on the transmission shaft are divided into two sections with the midpoint of the transmission shaft as the center, and the rotation directions of the two sections of the spiral blades are opposite. An auger discharge port 11 is opened on the side of the auger conveyor 1 close to the extruder 2, and the auger discharge port 11 is located at the midpoint of the transmission shaft. The auger discharge port 11 passes through the placement rack 3 and corresponds to the feeding port 21 of the extruder 2 in the height direction. The top of the auger conveyor 1 has a feed port, and the feed port is arranged along the length direction of the auger conveyor 1. Therefore, the raw materials entering the auger conveyor 1 from the loss-in-weight scale 4 will be transported from both sides to the middle, and finally enter the feeding port 21 of the extruder 2 from the auger discharge port 11.

[0031] Reference Figure 1, multiple loss-in-weight scales 4 can be set up on the auger conveyor 1 by relying on the placement rack 3. The loss-in-weight scales 4 are distributed along the length direction of the auger conveyor 1 and are distributed on both sides of the width direction of the auger conveyor 1. The discharge port of the loss-in-weight scale 4 is inclined toward the direction of the auger conveyor 1 and is connected with the feed port of the auger conveyor 1. In this way, multiple loss-in-weight scales 4 can be set up and the normal operation of the loss-in-weight scales 4 can be ensured, thereby solving the problem that multiple loss-in-weight scales 4 cannot be placed and installed, and it is more intensive and space-saving. It should be particularly noted here that the loss-in-weight scales 4 include a particle loss-in-weight scale 41 and a powder loss-in-weight scale The weighing scale 42 and the particle loss-in-weight scale 41 can weigh and measure the particle raw materials, and the powder loss-in-weight scale 42 can weigh and measure the powder raw materials. The particle loss-in-weight scale 41 is distributed on both sides of the midpoint of the transmission shaft, and the powder loss-in-weight scale 42 is set at the midpoint of the transmission shaft. When the auger conveyor 1 is working, the particle raw materials on both sides of the auger conveyor 1 can be transported to the middle by the rotation of the spiral blades in opposite directions of rotation, thereby driving the powder raw materials in the middle to be discharged from the auger discharge port 11, ensuring that the powder raw materials will not remain in the auger conveyor 1, thereby improving the discharge effect of the auger conveyor 1.

[0032] Reference Figure 1 The auger discharge port 11 is detachably connected to a connecting pipe 5 by means of a flange, and the connecting pipe 5 extends downward to the inside of the feeding port 21 and is connected to the feeding port 21. The connecting pipe 5 guides the raw materials into the feeding port 21, and the raw materials will not float into the external environment during this process, especially the powder raw materials, thereby avoiding the waste of raw materials and the pollution of the external environment. The connecting pipe 5 can also be disassembled so that the inside of the connecting pipe 5 can be cleaned regularly to prevent the connecting pipe 5 from being blocked and affecting the normal feeding operation of the extruder 2. The end of the connecting pipe 5 extending into the feeding port 21 is provided with a dust cloth 6, which blocks the feeding end of the feeding port 21. An opening is provided in the middle of the dust cloth 6, and the connecting pipe 5 passes through the dust cloth 6 from the opening. A circle of rubber band rope 7 is provided at the opening of the dust cloth 6, which is tightened on the outer wall of the connecting pipe 5 by its own elastic force, so that the dust cloth 6 and the connecting pipe 5 can be connected and fixed, so that the dust cloth 6 will not fall off the connecting pipe 5 spontaneously, and the end of the dust cloth 6 away from the connecting pipe 5 hangs down along the outer wall of the feeding port 21. The dust cloth 6 prevents foreign matter in the external environment from entering the feeding port 21, and prevents the powder raw material from floating outward into the external environment. The dust cloth 6 can also be removed from the connecting pipe 5 manually, which is convenient for regular cleaning of the dust cloth 6.

[0033] Reference Figure 1 An elliptical observation mirror 8 is provided on the side wall of the feeding port 21 of the extruder 2. The worker can observe the feeding situation inside the feeding port 21 in real time through the observation mirror 8 so as to better grasp the feeding situation of the extruder 2.

[0034] The implementation principle of a multi-group feeding and conveying device in an embodiment of the present application is as follows: after the loss-in-weight scale 4 completes the weighing and metering of the raw materials, the raw materials are conveyed into the auger conveyor 1, and the rotation of the transmission shaft drives the two sections of spiral blades with opposite rotation directions to rotate, which can transport the granular raw materials on both sides of the auger conveyor 1 to the middle, and the granular raw materials carry the powder raw materials into the feeding port 21 through the auger discharge port 11 and the connecting pipe 5. It should be noted that the auger conveyor 1 is installed and fixed on the placement rack 3, so that multiple loss-in-weight scales 4 can be set up on the auger conveyor 1 by relying on the placement rack 3, and the loss-in-weight scales 4 are distributed along the length direction of the auger conveyor 1, and are distributed on both sides of the width direction of the auger conveyor 1, so the problem that multiple loss-in-weight scales 4 cannot be placed and installed can be solved.
