Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, and particularly relates to a plastic particle softening device. Background Technique

[0002] Plastic processing is the general term for various processes that convert synthetic resins or plastics into plastic products, and the softening of plastic particles is an essential step in the plastic processing process.

[0003] Chinese Utility Model Publication No.: CN219946865U includes a bracket, a softening barrel, a sealing cover and an electric heating tube. A chute is provided on the bracket, a moving seat is slidably connected to the bracket, a slider is fixedly connected to the moving seat, a heat preservation barrel is fixedly connected to the moving seat, a first motor is installed on the bracket, and an output shaft of the first motor is fixedly connected to a screw rod, and the screw rod is in threaded connection with a threaded hole provided on the moving seat. In the utility model, after heating is completed, the first motor is started, so that the moving seat moves downward in the vertical direction, resulting in the separation of the sealing cover from the softening barrel. The staff can take out the softening barrel from the heat preservation barrel through the side block. Since the side block is not heated by the electric heating tube and the side block is in contact with the environment, the temperature of the side block will not scald the staff, avoiding scalding the staff when taking out the softening barrel.

[0004] The applicant found that there are some deficiencies in the use of this patent: it is convenient to take out the softening barrel through the side block to avoid scalding the hand, but when the sealing cover and the softening barrel are separated, the hot air in the softening barrel gushes out, and the face of the staff may be scalded during the process of taking out the softening barrel. Therefore, it is necessary to wait until the hot air in the softening barrel dissipates to a certain extent, and waiting takes a certain amount of time. During this process, the softening operation cannot be continued, affecting the softening efficiency.

[0005] Therefore, the utility model designs a plastic particle softening device to solve the problems existing in the prior art. Content of the Utility Model

[0006] The purpose of the utility model is to provide a plastic particle softening device to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a plastic particle softening device, including: a mounting frame, two heat preservation barrels are provided on the mounting frame, a softening barrel is slidably installed in the heat preservation barrel, two electric cylinders are installed on the inner wall of the top of the mounting frame, and output ends of the two electric cylinders are respectively fixedly installed on both sides of the top of the barrel cover. Heating tubes are provided at both ends of the bottom of the barrel cover, a stirring mechanism is provided in the middle of the barrel cover, a switching mechanism for switching the positions of the two heat preservation barrels is provided at the bottom of the mounting frame, and a controller is installed on one side of the mounting frame.

[0008] Preferably, the stirring mechanism includes a stirring shaft rotatably installed at the center of the cylinder cover. A number of stirring blades are provided below the outer sidewall of the stirring shaft. The top of the stirring shaft is connected to the output end of a stirring motor. The stirring motor drives the stirring shaft to rotate, causing the stirring blades to rotate and stir the plastic particles, improving the softening effect.

[0009] Preferably, the switching mechanism includes a bottom groove opened at the bottom of the mounting frame. A switching motor is installed in the bottom groove. The output end of the switching motor is connected to the middle of the bottom of a rotating plate. The two heat preservation cylinders are respectively installed at both ends of the top of the rotating plate. After the softening is completed, the switching motor drives the rotating plate to rotate 180 degrees, causing the other softening cylinder to rotate to directly below the cylinder cover, and then the plastic particles can be continuously softened. During the softening process, when the heat of the rotated-out softening cylinder dissipates to a certain extent, the staff can take it out. During the waiting process, the softening operation can also continue, improving the softening efficiency.

[0010] Preferably, a number of rollers are installed at the bottom of the rotating plate and are in rolling connection with the inner wall of the bottom of the mounting frame. When the rotating plate rotates, it drives the rollers to roll on the mounting frame, which can reduce the friction of the rotating plate during rotation.

[0011] Preferably, clamping grooves are opened on both sides of the top of the heat preservation cylinder. Clamping blocks are installed above both sides of the softening cylinder and are clamped in the clamping grooves, which can limit the positions of the heat preservation cylinder and the softening cylinder.

[0012] Preferably, a handle is installed on one side of the clamping block, which is convenient for taking out the softening cylinder from the heat preservation barrel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Through the setting of the switching mechanism of the present utility model, after the softening is completed, the switching motor drives the rotating plate to rotate 180 degrees, causing the other softening cylinder to rotate to directly below the cylinder cover, and then the plastic particles can be continuously softened. During the softening process, when the heat of the rotated-out softening cylinder dissipates to a certain extent, the staff can take it out. During the waiting process, the softening operation can also continue, improving the softening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figure 3 , in this embodiment: clamping grooves 9 are opened at both sides of the top of the heat preservation cylinder 2, and clamping blocks 10 that are clamped with the clamping grooves 9 are installed above both sides of the softening cylinder 3.

[0025] Please refer to Figure 3 , in this embodiment: A grip 11 is installed on one side of the clamping block 10, and a rubber sleeve is sleeved on the outer wall of the grip.

[0026] Working principle: Pour the plastic particles to be softened into the softening cylinder 3, then place the softening cylinder 3 into the heat preservation cylinder 2. The clamping block 10 is stuck in the clamping groove 9 to limit the softening cylinder 3. The electric cylinder 4 drives the cylinder cover 5 to descend so that the cylinder cover 5 contacts the top of the heat preservation cylinder 2.
