Description

Technical Field

[0001] This application relates to the field of trimming material drying equipment, and more particularly to a frozen trimming material dryer. Background Technology

[0002] A cryogenic trimming machine is a device used to replace manual deburring of rubber molded parts, precision injection molded parts, and die-cast parts. It is one of the essential downstream processing equipment in the rubber and plastics and die-casting industries. The working principle of the cryogenic trimming machine mainly utilizes the low-temperature freezing effect of liquid nitrogen to make rubber, plastic, or zinc-magnesium-aluminum alloy products brittle. During the time difference between the burrs on the product and the product becoming brittle, a high-speed jet of polymer particles impacts the burrs, thereby removing them efficiently and with high precision.

[0003] Because impurities may adhere to the edges after trimming, it is usually necessary to clean and dry them before proceeding.

[0004] Existing drying equipment typically uses electric heating elements to heat the interior of the chamber. By using high temperatures, the moisture on the surface evaporates, thus achieving proper drying. However, due to the large number of items and their stacking together, the drying time is long and the drying effect is poor. Utility Model Content

[0005] In order to shorten the drying time while ensuring the drying effect, this application provides a freeze-dried trimming material dryer.

[0006] The technical solution of the freeze-dried trimming material dryer provided in this application is as follows:

[0007] A freeze-dried trimming material dryer includes a support frame, an outer casing, and a drum. The outer casing is mounted on the support frame, and the drum is rotatably connected inside the outer casing. A drum drive device is provided on the support frame to drive the drum to rotate. The dryer also includes a fan, a hot air box, and a hot air pipe. The fan and the hot air box are mounted on the support frame. The fan is connected to the hot air box, and the hot air pipe is connected to the hot air box. The hot air pipe is disposed inside the drum and has an air outlet.

[0008] By adopting the above technical solution, the drum drive device is installed on the support frame and fixedly connected to the drum. By driving the drum to rotate, the drum inside the drum is rotated to remove excess water. Then, air is blown through the hot air box of the fan box, which heats the air. The hot air is then circulated into the drum through the hot air pipe for drying, thereby shortening the drying time while ensuring the drying effect.

[0009] In one specific implementation, a spiral guide plate is provided inside the drum, and the spiral guide plate is spirally arranged on the inner side wall of the drum, forming a spiral channel between adjacent plates of the spiral guide plate.

[0010] By adopting the above technical solution, the spiral guide plate is installed inside the drum, and a spiral channel is formed between the adjacent plates of the spiral guide plate. This allows for continuous transport of the material in the direction of the box outlet while separating materials with inconsistent drying levels, thereby further ensuring the drying effect.

[0011] In one specific implementation, the roller sidewall is provided with a plurality of filter holes, which are distributed in a dispersed manner.

[0012] By adopting the above technical solution, multiple filter holes are set on the side wall of the drum. When the drum rotates, the water on it is thrown out and discharged through multiple filter holes, thereby avoiding water accumulation and affecting the drying effect.

[0013] In one specific implementation, a support rod is also included, which is mounted on a support frame. A support roller is provided at the end of the support rod away from the support frame, and the support roller is supported on the roller.

[0014] By adopting the above technical solution, the support rod is installed on the support frame, and the roller is supported by the support rollers set on the support rod, thereby ensuring the stability of the roller when it rotates.

[0015] In one specific implementation scheme, the hot air duct is provided with a plurality of air outlets, which are evenly installed along the length of the hot air duct.

[0016] By adopting the above technical solution, the hot air pipe is provided with several air outlets, which are evenly arranged along the length of the hot air pipe. This allows the hot air blown out from different parts inside the drum to be dried, ensuring a constant temperature inside the drum and thus further ensuring the drying effect.

[0017] In one specific implementation, the roller drive device includes a drive motor and a timing belt. The drive motor is mounted on the support frame, a drive wheel is mounted on the output shaft of the drive motor, a toothed ring is mounted on the circumferential part of the roller, and the timing belt is sleeved on both the toothed ring and the drive wheel.

[0018] By adopting the above technical solution, the drive motor drives the drive wheel to rotate. Since the drive wheel and the toothed ring set on the drum are both fitted with a synchronous belt, the drive motor can drive the drum to rotate, thereby achieving the flipping of the drum and accelerating the evaporation of the water.

[0019] In one specific implementation, a first baffle plate is also included, which is installed on the side of the outer casing adjacent to the discharge port of the roller.

[0020] By adopting the above technical solution, the setting of the first baffle plate facilitates the receiving of dried materials and prevents them from falling off.

[0021] In one specific implementation scheme, a second baffle plate is further included, which is installed below the first baffle plate. The outlets of the second baffle plate and the first baffle plate are arranged opposite to each other, and the outlet of the first baffle plate is located above the second baffle plate.

[0022] By adopting the above technical solution, the second baffle is set below the first baffle, and the discharge port of the first baffle is set above the second baffle, which plays a buffering role and prevents the material from falling due to excessive discharge height.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The drum drive device is installed on the support frame and is fixedly connected to the drum. By driving the drum to rotate, it drives the tumbling inside the drum to spin off excess water. Then, air is blown through the hot air box of the fan box. The hot air box heats the air and then the hot air is sent to the drum through the hot air pipe for drying. This shortens the drying time while ensuring the drying effect.

[0025] 2. The spiral guide plate is installed inside the drum, and the spiral channel is formed between the adjacent plates of the spiral guide plate. This allows for continuous transport of the material in the direction of the box outlet while separating materials with inconsistent drying levels, thereby further ensuring the drying effect.

[0026] 3. Multiple filter holes are set on the side wall of the drum. When the drum rotates, the water on it is thrown out and discharged through multiple filter holes, thereby avoiding water accumulation and affecting the drying effect. Attached Figure Description
