A barrel support frame for a tpu extruder

Abstract

The invention discloses a supporting frame for a machine barrel of a TPU extruding machine. The supporting frame for the machine barrel of the TPU extruding machine comprises a base, supporting postssymmetrically arranged at the two ends of the base, L-shaped locking blocks fixed to the bottom surfaces of the two ends of the machine barrel through bolts, and connecting mechanisms fixed to the topsurfaces of the supporting posts and movably connected with the locking blocks. A square groove is formed in the middle of the top surface of each supporting post. Each connecting mechanism comprisesan I-shaped connecting block and pressing blocks, wherein the bottom of the connecting block is inserted into the corresponding groove and spaced from the lateral wall of the groove, and the upper surface of the connecting block is flush with the upper surface of the corresponding supporting post; the two pressing blocks are arranged symmetrically relative to the center of the groove and press the bottom of the connecting block into the groove, and a through hole through which the middle of the connecting block penetrates is formed in the center; and the upper portion of the connecting blockis connected with the bottom of the corresponding locking block through bolts. Thus, the supporting frame for the machine barrel of the TPU extruding machine has the advantages of long service life, high working efficiency and high practicality.

Description

technical field [0001] The present disclosure generally relates to the field of TPU production, and in particular relates to a barrel support frame of a TPU extruder. Background technique [0002] TPU extruders are widely used in the processing and molding of TPU. During the use of TPU extruders, it is generally required to reach a certain height for easy operation. Therefore, there is generally a The support frame, the existing TPU extruder barrel support frame generally consists of a base and a fixed arm located on the base, and the fixed arm is directly connected to the barrel with bolts or screws. During the working process, the TPU extruder barrel is often heated to 100-150°C. At this time, for large and medium-sized TPU extruders, the total expansion length of the barrel usually increases by 10-15mm or more. Therefore, in the TPU extruder Under the rigidly connected structure of the barrel and the support frame, the huge expansion force of the barrel of the TPU extrud...

Problems solved by technology

During the working process, the TPU extruder barrel is often heated to 100-150°C. At this time, for large and medium-sized TPU extruders, the total expansion length of the barrel usually increases by 10-15mm or more. Therefore, in the TPU extruder Under the rigidly connected structure of the barrel and the support frame, the huge expansion force of the TPU extruder barrel usually pulls and deforms the support frame on the one hand, which makes the service life of the support frame short and the maintenance workload is large; on the other hand , which also makes the production stability of the TPU extruder poor, making it difficult to achieve high-speed and high-efficiency production
