Description

Technical Field

[0001] The present application relates to the field of pelletizer technology, and in particular to a novel water ring pelletizer. Background Art

[0002] The water ring pelletizer is mainly used to process waste plastics. After the strips extruded by the extruder are extruded through the die, they are cooled with water and immediately cut with a rotating knife to form pellets required for factory processing.

[0003] The existing water ring pelletizer usually installs the knife shaft assembly directly on the template of the discharge port. Due to the long-term rotation of the knife shaft assembly, the friction generated when the connection between the knife shaft assembly and the template rotates, and the high temperature of the template itself, which is usually between 200℃-300℃, will make the oil temperature at the connection too high. After working for a long time, it is easy to cause bearing damage, thus affecting the service life of the machine. Utility Model Content

[0004] In order to reduce the impact on the service life of bearings, the present application provides a new type of water ring pelletizer.

[0006] A novel water ring pelletizer comprises a workbench, an extruder and a template, wherein the extruder is mounted on the workbench, and the template is mounted on one end of the extruder discharging material. The machine also comprises a cutting motor, a connecting knife shaft, a water ring shell, a clamping mechanism and a cutting tool, wherein the cutting motor and the water ring shell are mounted on the workbench, one end of the connecting knife shaft is connected to the cutting motor, and the connecting knife shaft is arranged through the water ring shell, the clamping mechanism comprises a clamping block and a clamping spring, the clamping block is slidably connected to the connecting knife shaft, the clamping spring is sleeved on the connecting knife shaft, one end of the clamping spring is connected to the connecting knife shaft, and the other end of the clamping spring is connected to the clamping block, and the cutting tool is arranged on the clamping block, so that the cutting tool is abutted against the template.

[0007] By adopting the above technical solution, one end of the connecting knife shaft is installed on the output shaft of the cutting motor, and the clamping block is slidably connected to the other end of the connecting knife shaft, and the cutting tool is installed on the clamping block. The clamping spring applies force to the clamping block, so that the cutting tool set on the clamping block is clamped to the template. This replaces the previous method of directly rotating the connecting knife shaft with the template installed on the extruder. Since the temperature of the template itself is relatively high, it will cause the problem of excessive oil temperature at the connection, which reduces the impact on the service life of the connecting knife shaft and the template. The buffering capacity of the clamping spring can appropriately adjust the degree of compression of the clamping spring on the clamping block according to the production of different materials.

[0008] In a specific feasible implementation scheme, the cutting tool includes a tool holder, a blade, a steering block and a steel ball, the tool holder is provided with a steering block mounting groove, the inner wall of the steering block mounting groove is provided with a steel ball slide groove, the steering block is provided with a steel ball mounting groove, the steering block is installed in the steering block mounting groove, and the steel ball is located between the steering block mounting groove and the steel ball mounting groove, and can rotate relative to the steering block mounting groove and the steel ball mounting groove, and the steering block is threadedly connected to the clamping block.

[0009] By adopting the above technical solution, the steering block is threadedly connected to the connecting knife shaft, and the steel ball is installed between the steel ball installation groove and the steering block installation groove, so that the steering block is rotated and connected to the tool holder through the steel ball, so that the tool holder can rotate relative to the connecting knife shaft, adjust the angle of the tool holder, and make the tool holder always fit well with the template, thereby ensuring the pelletizing effect of the blade.

[0010] In a specific possible implementation manner, a plurality of the blades are provided, and the plurality of the blades are mounted on a circumferential portion of the blade holder.

[0011] By adopting the above technical solution, the material extruded by the extruder is pelletized by multiple blades at the same time, thereby further ensuring the pelletizing effect of the blades.

[0012] In a specific possible implementation scheme, two steel balls are provided, and the two steel balls are symmetrically installed on both sides of the steering block, and the number and positions of the steel ball sliding grooves and steel ball installation grooves correspond to the steel ball settings.

[0013] By adopting the above technical solution, two steel balls are symmetrically installed on both sides of the steering block, thereby ensuring the smoothness of the rotation of the tool holder relative to the steering block and ensuring the stability of the connection between the tool holder and the steering block.

[0014] In a specific possible implementation scheme, the clamping mechanism also includes a mounting seat, the mounting seat is threadedly connected to the connecting knife shaft, a sliding block is provided on the connecting knife shaft, a key slot is provided on the inner side wall of the clamping block, and the sliding block is slidably connected in the key slot, so that the clamping block is slidably connected to the connecting knife shaft.

[0015] By adopting the above technical solution, the clamping block is slidably connected to the connecting knife shaft through the keyway and slidably connected to the sliding block provided on the connecting knife shaft, so that the clamping block can only move along the length direction of the connecting knife shaft, thereby avoiding the clamping block from rotating during pelletizing, causing the clamping spring to twist, thereby causing wear of the clamping spring. At the same time, the blade will wear during use, but the setting of the clamping spring will ensure that the worn blade can still fit well on the template.

[0016] In a specific possible implementation scheme, it also includes a bearing box, the cutting motor is installed on the bearing box, and thus installed on the workbench, the bearing box is installed on the workbench, a bearing structure is arranged in the bearing box, and the connecting knife shaft is arranged through the bearing structure.

[0018] In a specific possible implementation scheme, the bearing structure includes a thrust bearing, an auxiliary bearing and a pressure bearing, and the thrust bearing, auxiliary bearing and pressure bearing are arranged in the bearing housing in sequence, and the connecting knife shaft passes through the thrust bearing, auxiliary bearing and pressure bearing in sequence.

[0019] By adopting the above technical solution, the connecting knife shaft is supported by the thrust bearing and the pressure bearing one in front and one in the back, and the front and rear are relatively arranged to form relative forces to prevent the knife shaft from shaking back and forth during operation. In addition, an auxiliary bearing member acts as a stabilizing device to further improve the stability of the connecting knife shaft.

[0020] In a specific possible implementation mode, a discharge port is provided on the side wall of the water ring shell, and the discharge port is arranged obliquely.

[0021] By adopting the above technical solution, when the water pump connected to the mold intakes water to cool the pelletizing opening, the waste particles and water generated by grinding splash onto the water ring shell, and the setting of the discharge port facilitates the outflow of water and the generated waste particles.

The cutting tool is installed on the clamping block, and a force is applied to the clamping block through the clamping spring, so that the cutting tool set on the clamping block is clamped on the template, replacing the previous connection method of the connecting knife shaft directly rotating with the template installed on the extruder. Due to the high temperature of the template itself, the oil temperature at the connection is too high, which reduces the impact on the service life of the connecting knife shaft and the template. The buffering capacity of the clamping spring can appropriately adjust the degree of compression of the clamping spring on the clamping block according to the production of different materials;

[0024] 2.
