Description

Technical Field

[0001] This utility model relates to the field of areca nut processing technology, specifically to a coarse fiber softening device for areca nut processing. Background Technology

[0002] Areca nut is the fruit of the areca tree, which is round or oblong in shape. After harvesting, fresh areca nuts undergo processes such as blanching, processing, drying, and polishing to become dried fruit, which then proceeds to slicing, brine application, and packaging. The dried areca nut has dense, hard fibers, making it prone to cracking and damage when sliced ​​directly, which also affects subsequent processing. Therefore, a softening treatment is necessary.

[0003] Currently, traditional betel nut softening methods rely on soaking, boiling, or chemical leavening agents, which have drawbacks such as long processing times, chemical residues, uneven softening of the fibers inside and out, and easy hardening back after drying. Although microwave heating can achieve rapid heating, betel nuts are prone to "outer ripening and inner stagnation" in a static state, reducing the overall softening effect. Utility Model Content

[0004] The purpose of this invention is to provide a coarse fiber softening device for areca nut processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coarse fiber softening device for areca nut processing, comprising: A frame is provided, in which a conveyor belt is installed. Multiple partition plates are fixed at equal intervals on the outer conveying surface of the conveyor belt. An interception assembly is provided in the middle of the upper side of the frame. The interception assembly includes two flexible baffles and an interception net. The interception net is fixed on the upper side of the two flexible baffles. The two flexible baffles are respectively located at the front and rear edges of the upper side of the conveyor belt. The bottom of the flexible baffles slides in cooperation with the upper surface of the conveyor belt. A fiber softening mechanism, comprising a softening box fixed to the upper middle part of the frame, wherein multiple microwave generators are installed at equal intervals on the top inner wall of the softening box; Multiple vibration mechanisms are located between the upper and lower belt bodies of the conveyor belt. The multiple vibration mechanisms are arranged at equal intervals along the length of the conveyor belt, and the vibration output end of the vibration mechanism is in elastic contact with the lower surface of the upper belt body of the conveyor belt.

[0006] Furthermore, the vibration mechanism includes a buffer seat, an electromagnetic vibrator, and an elastic transmission plate. The front and rear ends of the buffer seat are connected to the inner walls of the front and rear sides of the frame. The electromagnetic vibrator is mounted on the buffer seat, and the elastic transmission plate is mounted on the electromagnetic vibrator. The upper surface of the elastic transmission plate is evenly distributed with hemispherical rubber protrusions. The hemispherical rubber protrusions abut against the lower surface of the conveyor belt. The electromagnetic vibrator transmits vibration to the conveyor belt through the elastic transmission plate, causing the conveyor belt to vibrate and tumble, so that the fibers are heated and softened evenly inside and out. The hemispherical rubber protrusions can reduce friction with the conveyor belt.

[0007] Furthermore, the flexible baffle is connected to the inner wall of the frame, and the bottom of the flexible baffle is inlaid with balls at equal intervals. The balls abut against the upper surface of the conveyor belt, reducing the friction between the flexible baffle and the conveyor belt.

[0008] Furthermore, the partition plate on the conveyor belt is located between the two flexible baffles, the intercepting net is nested inside the softening box, the intercepting net is located above the partition plate, and the intercepting net is parallel to the upper surface of the conveyor belt. The intercepting net plays a role in intercepting the vibrating and tumbling areca nuts and preventing the areca nuts from jumping out.

[0009] Furthermore, the interception net is a glass fiber mesh coated with polytetrafluoroethylene, and the partition plate is made of polypropylene material, which has low microwave loss and does not generate heat itself.

[0010] Furthermore, both ends of the conveyor belt are fitted with drive rollers, a geared motor is installed on the front left side of the frame, the output end of the geared motor is connected to the front end of the drive rollers, and a PLC controller is installed on the front side of the frame. The output end of the PLC controller is electrically connected to the electromagnetic vibrator, the microwave generator and the geared motor respectively.

[0011] Furthermore, the top inner wall of the softening box is provided with multiple moisture-absorbing hoods, which are staggered with the microwave generators along the length of the softening box. An exhaust fan is installed on the top outer wall of the softening box, and the suction end of the exhaust fan is connected to a moisture-absorbing main pipe. The top of the moisture-absorbing hood is connected to a moisture-absorbing branch pipe, the upper end of which penetrates the top wall of the softening box and connects to the moisture-absorbing main pipe. The exhaust fan is electrically connected to a PLC controller. When the exhaust fan is working, it removes the water vapor released during fiber softening in real time through the moisture-absorbing hoods to prevent secondary moisture absorption and hardening.

[0012] Furthermore, a discharge guide plate is provided at the lower right end of the frame. The connection between the discharge guide plate and the frame is located at the bottom right end of the conveyor belt. The softened areca nuts on the conveyor belt fall from the right end of the conveyor belt onto the discharge guide plate and are discharged through the discharge guide plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By using microwave heating and a vibration mechanism to make the areca nuts on the conveyor belt vibrate and roll during the microwave heating process, the areca nut fibers are heated evenly inside and out at the same time, resulting in good softening consistency. 2. By installing an interception component on the conveyor belt, which consists of an interception net and two flexible baffles, the areca nuts that vibrate and tumble on the conveyor belt can be blocked and intercepted, preventing the areca nuts from jumping off the conveyor belt; 3. By evenly distributing hemispherical rubber protrusions on the upper surface of the elastic vibration plate, vibration can be transmitted, and the friction between the elastic vibration plate and the conveyor belt can be reduced, thus reducing wear on the conveyor belt.

Multiple partition plates 12 are fixed at equal intervals on the outer conveying surface of the conveyor belt 11. The partition plates 12 are made of polypropylene material, which has low microwave loss and does not generate heat itself. The fiber softening mechanism 20 includes a softening box 21, which is fixed to the upper middle part of the frame 10. Multiple microwave generators 22 are installed at equal intervals on the top inner wall of the softening box 21. Multiple vibration mechanisms 30 are located between the upper and lower belt bodies of the conveyor belt 11. The multiple vibration mechanisms 30 are arranged at equal intervals along the length of the conveyor belt 11, and the vibration output end of the vibration mechanism 30 is in elastic contact with the lower surface of the upper belt body of the conveyor belt 11.

[0019] The vibration mechanism 30 includes a buffer seat 31, an electromagnetic vibrator 32, and an elastic transmission plate 33. The front and rear ends of the buffer seat 31 are connected to the inner walls of the front and rear sides of the frame 10. The electromagnetic vibrator 32 is mounted on the buffer seat 31, and the elastic transmission plate 33 is mounted on the electromagnetic vibrator 32. The upper surface of the elastic transmission plate 33 is evenly distributed with hemispherical rubber protrusions 34. The hemispherical rubber protrusions 34 abut against the lower surface of the upper belt of the conveyor belt 11. The electromagnetic vibrator 32 transmits vibration to the conveyor belt 11 through the elastic transmission plate 33, causing the conveyor belt 11 to vibrate and drive the areca nuts on it to vibrate and roll, so that the fibers are heated and softened evenly inside and out. The hemispherical rubber protrusions 34 can reduce the friction between the fibers and the conveyor belt 11.

[0020] Both ends of the conveyor belt 11 are fitted with drive rollers 14. A geared motor 15 is installed on the front left side of the frame 10.
