Description

Technical Field

[0001] This utility model relates to the field of rubber roller technology for rice hullers, specifically a mechanism for stabilizing the spacing between rubber rollers in rice hullers. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. It mainly consists of a feeding device, a hulling device, a hulling material separation device, and a transmission device. The hulling device has a pair of rotating rubber rollers inside. The pair of rubber rollers includes a fixed roller, usually a fast roller, and a movable roller, usually a slow roller. In order to adapt to the hulling of paddy rice with different grain shapes and hardness, the distance between the two rubber rollers needs to be adjusted to ensure the best hulling effect.

[0003] Long-term friction between the rubber roller and the rice will cause the rubber roller to wear out, especially when the difference in linear speed between the two rubber rollers is too high, the wear will be more serious. In addition, the rubber roller is prone to aging after long-term outdoor use, which causes the rubber roller to lose its original round shape and become irregular. The out-of-round rubber roller will jump when rotating. Although the distance between the two rubber rollers can be adjusted by the cylinder, it is not easy to detect whether the rubber roller is out of round in time, which affects the stability of the cylinder in controlling the distance between the two rubber rollers. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for stabilizing the spacing between the rubber rollers of a rice huller, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mechanism for stabilizing the spacing between the rubber rollers of a rice huller includes:

[0007] Two support bases are rotatably installed at both ends of the fixed rubber roller;

[0008] Both support bases are slidably connected to the shelling device, and the two support bases are rotatably installed at both ends of the movable rubber roller, respectively.

[0009] Both cylinders are used to drive the two support seats to move in different positions;

[0010] Two carrier plates are fixed on both sides of the shelling device. A guide rail is fixed on the outer side of the carrier plate. A lead screw rotates inside the guide rail. A transmission seat that is slidably connected to the lead screw is spun inside the guide rail.

[0011] Two detection components are fixed on the outside of the corresponding transmission seat. Each detection component includes a sleeve, a sliding rod sliding inside the sleeve, a pressure sensor installed on the bottom surface of the sleeve, a compression spring between the sliding rod and the pressure sensor, and a roller rotating at one end of the sliding rod.

[0012] Furthermore, the cylinder is fixed to the inner side of the shell of the shell-removing device, and the output end of the cylinder is fixedly connected to the corresponding support seat.

[0013] Furthermore, a motor capable of driving the lead screw to rotate is fixed on the outer side of the carrier plate, and a slotted hole is opened through the outer side of the carrier plate, with the sleeve slidably connected to the slotted hole.

[0014] Furthermore, one end of the compression spring is fixed to the slide rod, and the other end of the compression spring abuts against the pressure-sensing element of the pressure sensor.

[0015] Furthermore, the end of the slide bar opposite to the compression spring is fixed with an i-shaped seat, and the i-shaped seat is rotatably connected to the roller.

[0016] Furthermore, the first support base is fixed to the external shell-removing device, the top surface of the shell-removing device has two sliding grooves, and the bottom of the two second support bases is fixed with an inverted plate, the inverted plate being slidably connected to the two sliding grooves.

[0017] Furthermore, both ends of the bottom surface of the C-shaped plate are fixed with sliders, the bottom surface of the sliders is fixed with iron blocks, and an electromagnet is embedded in the bottom surface of the groove, which is attracted and fixed to the iron blocks after being energized.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By fixing a C-shaped plate to the bottom of the support base two at both ends of the movable rubber roller, the C-shaped plate is slidably arranged inside the shelling device via a slider. When the cylinder drives the C-shaped plate to move the support base two and move the movable rubber roller to the appropriate shelling position, the electromagnet inside the slide groove of the shelling device is energized, causing the electromagnet to attract the iron block on the bottom surface of the fixed slider. This allows the C-shaped plate, after adjustment, to be firmly fixed on the shelling device, thereby maintaining a suitable gap between the movable rubber roller and the fixed rubber roller on the C-shaped plate and firmly fixing them inside the shelling device. This eliminates the need for the traditional method of relying solely on the output end of the cylinder to stabilize the position of the movable rubber roller, and to a certain extent, it helps to improve the stability of the distance between the two rubber rollers.

[0020] 2. Rollers are rolled and attached to the outer sides of both rubber rollers (including the movable rubber roller and the fixed rubber roller). When the rubber roller becomes out of round due to wear or aging, the rotating rubber roller will move the roller left and right. The roller will squeeze the compression spring through the shaped seat and the slide rod. This will cause one end of the compression spring to intermittently squeeze the pressure sensor. The user can indirectly judge whether the rubber roller is out of round by whether the pressure reading transmitted to the outside of the pressure sensor changes continuously (the pressure reading changes continuously, indicating that the rubber roller is out of round, and the pressure reading remains unchanged, indicating that the rubber roller is intact). This makes it easy for the user to find out-of-round rubber rollers in time and replace them, effectively preventing the out-of-round rubber roller from jumping and affecting the stability of the distance between the two rubber rollers.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, please refer to Figure 1 - Figure 5In this embodiment of the invention, a mechanism for stabilizing the spacing between the rubber rollers of a rice huller includes two support seats 100, each rotatably connected to both ends of a fixed rubber roller. The support seats 100 are fixed inside a hulling device. The device also includes two support seats 200, each rotatably connected to both ends of a movable rubber roller. The two support seats 200 are slidably connected inside the hulling device. Cylinders 300, capable of driving the corresponding support seats 200 to move, are fixed at both ends inside the hulling device. Carrier plates 400 are fixed on both sides of the hulling device. The outer sides of the carrier plates 400 are fixed... A guide rail 410 is fixed, and a lead screw 411 rotates inside the guide rail 410. A transmission seat 412 is slidably connected inside the guide rail 410 and screwed into the lead screw 411. A detection component 500 is provided on the outside of the transmission seat 412. The detection component 500 includes a sleeve 510 fixedly connected to the transmission seat 412. A slide rod 520 slides inside the sleeve 510. A pressure sensor 530 is installed on the inner bottom surface of the sleeve 510. A compression spring 540 is provided between the slide rod 520 and the pressure sensor 530. A roller 550 rotates at one end of the slide rod 520.

[0029] Specifically, by installing a slider 210 at the bottom of the conventional movable rubber roller, the iron block 211 on the bottom surface of the slider 210 can be attracted and fixed to the electromagnet on the shell removal device. After the position of the movable rubber roller is adjusted, the electromagnet can be attracted and fixed to the slider 210 to indirectly fix the position of the movable rubber roller, eliminating the need to rely solely on the output end of the cylinder 300 to stabilize the position of the rubber roller, which is beneficial to improving the stability of the distance between the two rubber rollers.

[0030] In addition, by rolling and abutting the outer side of the rubber roller, when the rubber roller is out of round and rotates, the roller 550 will carry the slide bar 520 to intermittently press the compression spring 540. The compression spring 540 will intermittently press the pressure sensor 530. The user can indirectly judge whether the rubber roller is out of round by whether the pressure reading of the pressure sensor 530 changes continuously. This makes it convenient for the user to find out-of-round rubber rollers in time and replace them, effectively preventing the stability of the distance between the two rubber rollers from being affected by the jumping of the out-of-round rubber roller.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the cylinder 300 is fixed to the inner side of the shell of the shelling device. A connecting block is fixed to the output end of the cylinder 300. The connecting block is fixedly connected to the corresponding support seat 200. When the output end of the cylinder 300 extends, the support seat 200 moves the movable rubber roller away from the fixed rubber roller, thereby increasing the distance between the two rubber rollers. When the output end of the cylinder 300 shortens, the support seat 200 moves the movable rubber roller closer to the fixed rubber roller, thereby decreasing the distance between the two rubber rollers.

[0032] In this embodiment, the transmission device's ability to drive the movable rubber rollers at different positions to rotate is prior art and will not be described in detail here.

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, a motor 430 capable of driving the lead screw 411 to rotate is fixed on the outer side of the carrier plate 400. A slotted hole 420 is provided through the outer side of the carrier plate 400. The sleeve 510 is slidably connected to the slotted hole 420. The motor 430 drives the lead screw 411 to rotate in the forward and reverse directions, which enables the transmission seat 412 to move back and forth linearly along the guide rail 410. This allows the transmission seat 412 to carry the sleeve 510 back and forth along the slotted hole 420, facilitating the movement of the roller 550 slidably mounted on one end of the sleeve 510 along the axial direction of the rubber roller. This allows the roller 550 to detect whether the rubber roller is out of round at different positions on the outer side of the rubber roller, achieving the effect of omnidirectional detection of whether the rubber roller is out of round.

[0034] In this embodiment, since the roller 550 is slidably installed inside the sleeve 510 via the slide bar 520, the roller 550 can still abut against the outside of the movable rubber roller after the position of the movable rubber roller is adjusted, so that the roller 550 can detect at all times whether the movable rubber roller is out of round due to aging or wear.

[0035] like Figure 5 As shown, in this embodiment, one end of the compression spring 540 is fixed to the slide rod 520, and the other end of the compression spring 540 abuts against the pressure sensing element of the pressure sensor 530, so that the elastic force of the slide rod 520 squeezing the compression spring 540 can be transmitted to the pressure sensor 530. The change in the pressure reading of the pressure sensor 530 indirectly reflects whether the rubber roller is out of round. At the same time, the compression spring 540 makes the slide rod 520 and the roller 550 fit tightly against the rubber roller, so that the roller 550 can transmit the jump of the out-of-round rubber roller in time.

[0036] like Figure 4 As shown, in this embodiment, a C-shaped seat 521 is fixed to one end of the slide rod 520 away from the compression spring 540. The C-shaped seat 521 is rotatably connected to the roller 550, so that the roller 550 is rotatably mounted on the end of the slide rod 520 away from the compression spring 540 through the C-shaped seat 521.

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, the support base 100 is fixed to the external shell removal device. The top surface of the shell removal device has two sliding grooves. The bottom of the two support bases 200 is fixed with a C-shaped plate. The C-shaped plate is slidably connected to the two sliding grooves. Both ends of the bottom surface of the C-shaped plate are fixed with sliders 210. The bottom surface of the sliders 210 is fixed with iron blocks 211. An electromagnet is embedded in the bottom surface of the sliding groove and is attracted and fixed to the iron blocks 211 after being energized.

[0038] In this embodiment, the slider 210 slides in the groove, which enables the shaped plate to move stably with the rubber rollers on the two support seats 200. At the same time, the electromagnet generates magnetism after being energized, which can attract and fix the iron block 211 on the slider 210, thereby making the slider 210 stably fixed inside the groove and improving the stability after the distance between the two rubber rollers is adjusted.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
