Description

Technical Field

[0001] This utility model belongs to the field of roll forming technology and relates to special equipment for forced feeding of roll forming machines, specifically a floating water-cooled forced feeder. Background Technology

[0002] Existing forced feeders have a screw shaft and a feed bin to house it. When the screw shaft rotates, the material in the feed bin is pushed between the pressure rollers below, and finally rolled into product lumps. When the material temperature reaches 1200℃, the feeder absorbs heat from the material, causing the temperature to rise, which seriously affects the structural strength and wear resistance of the feeder. The thermal expansion of the feeder caused by the temperature rise will also lead to huge interaction forces between components with different temperature gradients, and may even cause deformation or tearing of components, thus seriously affecting the stable operation of the equipment. Utility Model Content

[0003] In order to overcome the defects and deficiencies in the prior art, this utility model provides a floating water-cooled forced feeder with a structure that leaves a gap between the floating section and other components. Thermal expansion will not cause huge stress between the floating section and other components, thereby avoiding component deformation and damage. This ensures the structural strength and wear resistance of the feeder and avoids damage and failure of feeder components caused by thermal expansion.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a floating water-cooled forced feeder, comprising a feeding bin, a spiral shaft, a shaft drive, and a cheek plate assembly. The feeding bin has a feed inlet at its top, the spiral shaft is installed inside the feeding bin, and the shaft drive is installed at the top of the feeding bin and connected to the spiral shaft to drive the spiral shaft to rotate. The feeding bin has a mounting frame and a floating section at its bottom, with gaps between the floating section and the mounting frame and the feeding bin, respectively. The cheek plate assembly is located at the bottom of the mounting frame.

[0005] Preferably, the floating section is provided with a limiting ear, and the mounting bracket is provided with a limiting groove that matches the limiting ear.

[0006] Preferably, the floating section is spirally wound with a cooling water heat exchange tube, which is offset from the limiting ear.

[0007] The cooling water in the cooling water heat exchange tube continuously removes heat, preventing the floating section from becoming too hot, which can lead to reduced strength, decreased wear resistance, and severe thermal deformation.

[0008] Preferably, the spiral shaft has an internal cooling water channel, and the top of the spiral shaft has a rotary joint that matches the cooling water channel.

[0009] The shaft cooling water circuit can prevent the heat of the spiral shaft from being conducted to the shaft drive, ensuring the normal operation of the shaft drive.

[0010] Preferably, the cheek plate assembly includes a movable wear-resistant plate, an elastic propulsion device, and a mounting plate, wherein the movable wear-resistant plate has a plate cooling water channel inside.

[0011] The movable wear-resistant plate is pushed by an elastic propulsion device and always keeps close to the side of the pressure roller to ensure a good seal between the pressure rollers and avoid material leakage and pressure loss. The cooling water channel inside the movable wear-resistant plate continuously removes heat to prevent excessive temperature from causing weakening of strength, reduced wear resistance and severe thermal deformation.

[0012] Preferably, the mounting plate is provided with mounting ears that cooperate with limiting ears, and the mounting ears are fixed to the mounting bracket by bolt pairs.

[0013] The limiting ear is restrained between the mounting bracket and the mounting ear to ensure that the floating section is in the correct position.

[0014] Preferably, the outer side of the feeding hopper is equipped with a heat insulation layer to prevent heat damage to other nearby components or equipment. A temperature sensor is also installed to monitor the temperature of the feeding hopper and the material inside in real time, and to adjust the cooling water flow rate at various points according to the temperature.

[0015] This invention employs a structure with gaps between the floating section and other components. Thermal expansion will not cause huge stress between the floating section and other components, thereby avoiding component deformation and damage. This ensures the structural strength and wear resistance of the feeder and prevents damage and failure of feeder components caused by thermal expansion. Attached Figure Description

Detailed Implementation

[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] Example 1

[0024] like Figure 1-5 As shown, a floating water-cooled forced feeder includes a feed bin 102, a spiral shaft 202, a shaft drive 104, and a cheek plate assembly 301. The feed bin 102 has a feed inlet 101, a mounting frame 106, and a floating section 201. The floating section 201 has a limiting ear 401 and a gap between the floating section 201 and other components. A cooling water heat exchange tube 105 is spirally wound on the outside. One end of the spiral shaft 202 has a rotary joint 103, and the inside has a shaft cooling water channel 203. The shaft drive 104 is mounted on the feed bin 102 and drives the spiral shaft 202 to rotate. The cheek plate assembly 301 has a movable wear-resistant plate 303, an elastic propulsion device 302, and a mounting ear 501. The movable wear-resistant plate 303 has a cooling water channel 204 inside, and the mounting ear 501 is fixed to the mounting frame 106 by bolts.

[0025] Example 2

[0026] In this embodiment, a floating water-cooled forced feeder operates by feeding high-temperature granular material into the feed hopper 102 through the inlet 101. The material is initially compressed by the screw shaft 202 and fed between the pressure rollers 107. The floating section 201 absorbs heat from the material, causing its temperature to rise. Because there are gaps between the floating section 201 and other components, thermal expansion does not generate significant stress between the floating section 201 and other components, thus preventing component deformation and damage. Cooling water in the cooling water heat exchange pipe 105 continuously removes heat, preventing weakening of strength, reduced wear resistance, and severe thermal deformation caused by excessively high temperatures in the floating section 201. The limiting ear 401 is restricted between the mounting bracket 106 and the mounting ear 501 to ensure that the floating section 201 is in the correct position; the shaft cooling water channel 203 can prevent the heat of the spiral shaft 202 from being conducted to the shaft drive 104, ensuring the normal operation of the shaft drive 104; the movable wear-resistant plate 303 is pushed by the elastic propulsion device 302 and always sticks to the side of the pressure roller 107 to ensure good sealing between the pressure rollers 107 and avoid material leakage and pressure loss; the cooling water channel 204 inside the movable wear-resistant plate 303 continuously removes heat to prevent excessive temperature from causing weakening of strength, reduced wear resistance and serious thermal deformation.

[0027] The feed hopper 102 has an insulation layer to prevent other nearby components or equipment from being damaged by heat.

[0028] The feed hopper 102 is equipped with a temperature sensor to monitor the temperature of the feed hopper 102 and the material inside in real time, and adjust the flow rate of cooling water at various points according to the temperature.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
