Description

Technical Field

[0001] This utility model relates to the field of masterbatch processing, and in particular to a spiral feeder for modified color masterbatch with cooling function. Background Technology

[0002] Masterbatch, also known as plastic masterbatch, is a plastic processing aid developed in the 1980s. It consists of a large amount of chemical additives, carrier resin, and dispersants. Masterbatch is an aggregate obtained by uniformly loading a large amount of pigment into resin. In plastic processing, masterbatch refers to the granular material produced by mixing various additives, fillers, and a small amount of carrier resin for ease of operation during the molding process. This mixture is then metered, mixed, melted, extruded, and pelletized using equipment such as extruders. Masterbatch is composed of carrier resin, various fillers, and various additives. The amount of additives or fillers in masterbatch is several to ten times higher than the amount required in the actual plastic product. During molding, the ratio of masterbatch to matrix resin must be adjusted according to the content of relevant components in the masterbatch and the amount required in the actual product. Masterbatch can generally be divided into ordinary filler masterbatch and functional masterbatch, such as color masterbatch and anti-fogging masterbatch.

[0003] However, modified masterbatch requires the use of a screw feeder for feeding during the production process. However, traditional screw feeders, such as the one disclosed in patent application number CN202123223259.7 (invention title: Screw Feeder), do not cool the masterbatch during feeding. However, high-temperature masterbatch can negatively impact subsequent processing. Utility Model Content

[0004] Therefore, it is necessary to provide a modified color masterbatch screw feeder with cooling function to address the problem that traditional screw feeders do not cool the masterbatch during the feeding process, and that high-temperature masterbatch will affect the technical issues of subsequent processing.

[0005] A modified masterbatch screw feeder with cooling function includes: a feed cylinder, a drive mechanism, and an air-cooling mechanism.

[0006] A conical feeding funnel is provided at the top of one end of the material transfer cylinder, and a discharge cylinder is provided at the bottom of the end of the material transfer cylinder away from the conical feeding funnel.

[0007] The driving mechanism includes a connecting box, a drive motor, a drive tube, and spiral blades. The drive motor is housed in the connecting box and connected to the inner wall of the connecting box. The connecting box is located near the end of the material transfer cylinder close to the conical feeding funnel. The top of the connecting box has several heat dissipation holes. The drive motor is driven by the drive tube, which is housed in the material transfer cylinder. The end of the drive tube away from the drive motor is rotatably connected to the end of the material transfer cylinder near the discharge cylinder. The spiral blades are adapted to the material transfer cylinder and are housed in the material transfer cylinder. The spiral blades are disposed on the drive tube, and several air outlet holes are evenly distributed on the portion of the drive tube housed in the material transfer cylinder.

[0008] The air-cooling mechanism includes an air conditioner, a three-way connector, a first cold air duct, a rotary connector, a second cold air duct, an electric valve, and a temperature sensor. The output end of the air conditioner is connected to the first end of the three-way connector, the second end of the three-way connector is connected to the input end of the first cold air duct, and the third end of the three-way connector is connected to the input end of the second cold air duct. The output end of the first cold air duct is connected to the input end of the rotary connector, and the output end of the rotary connector is connected to the end of the drive pipe away from the drive motor. The rotary connector is connected to the material transfer cylinder. The electric valve is located at the input end of the second cold air duct, and the output end of the second cold air duct is connected to the bottom of the connecting box. The temperature sensor is located inside the connecting box.

[0009] In one embodiment, the drive motor is a stepper motor.

[0010] In one embodiment, the drive motor is a servo motor.

[0011] In one embodiment, the conical feeding funnel and the material transfer cylinder are integrally formed.

[0012] In one embodiment, the conical feeding funnel is detachably connected to the material transfer cylinder.

[0013] In one embodiment, the discharge cylinder and the transfer cylinder are integrally formed.

[0014] In one embodiment, each of the heat dissipation holes is evenly distributed on the connecting box.

[0015] In one embodiment, the first cooling duct is a soft silicone tube.

[0016] In one embodiment, the second cold air duct is a soft silicone tube.

[0017] In one embodiment, the helical blade is integrally formed with the drive tube.

[0018] The modified masterbatch screw feeder with cooling function described above operates by feeding the modified masterbatch to be conveyed into one end of the conveying cylinder through a conical feeding funnel. The drive motor drives the screw blades to rotate via a drive pipe. The rotating screw blades convey the modified masterbatch to the end of the conveying cylinder furthest from the drive motor and finally discharge it through the discharge pipe. During the rotation of the screw blades, an air conditioner supplies cold air to the drive pipe through a three-way connector, a first cold air duct, and a rotating connector. The drive pipe then discharges cold air into the conveying cylinder through various air outlets, thus uniformly and thoroughly cooling the modified masterbatch in the conveying cylinder. The temperature sensor and electric valve are electrically connected to an external control mechanism. The drive motor generates a large amount of heat during operation. When the temperature sensor detects that the temperature inside the connection box is higher than a first preset temperature value, the external control mechanism controls the electric valve to open, and the air conditioner supplies cold air to the connection box through the three-way connector and a second cold air duct to cool the drive motor. When the temperature inside the connection box is lower than the first preset temperature value, the external control mechanism controls the electric valve to close. The modified masterbatch screw feeder with cooling function described above can cool down the masterbatch during the feeding process. Attached Figure Description

In another embodiment, the conical feeding funnel 110 and the material transfer cylinder 100 are detachably connected. A discharge cylinder 120 is provided at the bottom of the end of the material transfer cylinder 100 away from the conical feeding funnel 110.

[0027] The drive mechanism 200 includes a connecting box 210, a drive motor 220, a drive tube 230, and a spiral blade 240. In this embodiment, the drive motor 220 is a stepper motor. In another embodiment, the drive motor 220 is a servo motor. The drive motor 220 is housed within the connecting box 210 and connected to the inner wall of the connecting box 210. The connecting box 210 is connected to the end of the transfer cylinder 100 near the conical feeding funnel 110. A plurality of heat dissipation holes 201 are provided on the top of the connecting box 210. In this embodiment, the heat dissipation holes 201 are evenly distributed on the connecting box 210. The drive motor 220 is driven by the drive tube 230, which is housed in the transfer cylinder 100. The end of the drive tube 230 away from the drive motor 220 is rotatably connected to the end of the transfer cylinder 100 near the discharge cylinder 120. The spiral blade 240 is adapted to the transfer cylinder 100 and is housed within the transfer cylinder 100. The spiral blade 240 is disposed on the drive tube 230. In this embodiment, the spiral blade 240 and the drive tube 230 are integrally formed. The portion of the drive tube 230 that is housed in the material transfer cylinder 100 has a plurality of air outlet holes 202 evenly distributed on it.

[0028] The air-cooled mechanism 300 includes an air conditioner 310, a three-way connector 320, a first cold air duct 330, a rotary connector 340, a second cold air duct 350, an electric valve 360, and a temperature sensor 370. The output end of the air conditioner 310 is connected to the first end of the three-way connector 320, the second end of the three-way connector 320 is connected to the input end of the first cold air duct 330, and the third end of the three-way connector 320 is connected to the input end of the second cold air duct 350.

The temperature sensor 370 and the electric valve 360 ​​are both electrically connected to an external control mechanism. The drive motor 220 generates a large amount of heat during operation. When the temperature sensor 370 detects that the temperature inside the connection box 210 is higher than the first preset temperature value, the external control mechanism controls the electric valve 360 ​​to open. The air conditioner 310 then delivers cold air to the connection box 210 through the three-way connector 320 and the second cold air duct 350 to cool the drive motor 220. When the temperature inside the connection box 210 is lower than the first preset temperature value, the external control mechanism controls the electric valve 360 ​​to close. The modified masterbatch screw feeder 10 with cooling function can cool the masterbatch during the feeding process.
