Description

Technical Field

[0001] This utility model relates to a shelling device, and more particularly to an apricot kernel shelling machine. Background Technology

[0002] The first step in processing almond products is shelling, which involves breaking open the almond kernels to remove them. Because almond kernels vary in size and shape, and different varieties and batches have significantly different shapes, and their shells are thick and hard, shelling is quite difficult.

[0003] Utility model patent CN203538305U discloses an apricot kernel shelling machine, including a frame, a drive roller, a driven roller, a motor, and a belt drive device. The drive roller and driven roller are mounted side by side on the frame, and the motor is connected to the drive roller via the belt drive device. The key feature is that the driven roller is a free roller, mounted on the frame via two sets of spacing adjustment devices. In this shelling machine, the driven roller is mounted on the frame via two sets of spacing adjustment devices and is not connected to the motor. During operation, the drive roller transmits power to the driven roller through the apricot kernel, achieving reverse differential rotation between the two rollers, causing the apricot kernel to be shelled under the friction and compression of the drive roller and the driven roller. However, in actual use, the driven roller is difficult to rotate immediately under the friction between the drive roller and the apricot kernel. If the feed amount is too large, jamming frequently occurs, resulting in a low shelling rate, low work efficiency, and low output. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an apricot kernel shelling machine that can realize active reverse differential rotation of the passive roller and the active roller, and the distance between the passive roller and the active roller can be adjusted when the passive roller rotates, resulting in high working efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Apricot kernel shelling machine includes a frame, on which a drive motor, a drive roller, and a driven roller are mounted. The drive motor and the drive roller are connected via a belt drive mechanism. The machine is unique in that one end of the drive roller and the corresponding end of the driven roller are differentially connected via a chain drive mechanism. The chain drive mechanism includes a drive wheel, a driven wheel, and an intermediate wheel. The drive wheel is located at one end of the drive roller. The intermediate wheel is rotatably mounted on the frame via a wheel axle and connected to the drive wheel via a chain. The driven wheel is located at the corresponding end of the driven roller and meshes with the chain. The diameters of the driven wheel and the intermediate wheel are approximately equal to, but smaller than, the diameter of the drive wheel, used to achieve accelerated rotation of the driven roller relative to the drive roller.

[0007] A pair of slide rails are arranged vertically at both ends of the passive roller on the frame. The two ends of the passive roller are slidably mounted between the pair of slide rails through sliding bearing seats. A screw drive mechanism is provided between the sliding bearing seats and the frame to adjust the distance between the passive roller and the active roller in real time.

[0008] As a further preferred embodiment, an upper cover is fixed on the frame, which holds the active roller and the passive roller in place; a feed nozzle is provided on the upper cover, the cross-section of which is wedge-shaped and the discharge port is located above the active roller and the passive roller to facilitate feeding.

[0009] As a further preferred embodiment, the upper feed port of the feed nozzle is rectangular, and the lower discharge port is elongated. Multiple radially arranged material distribution plates are evenly distributed inside the feed nozzle to uniformly disperse the input material.

[0010] As a further preferred embodiment, the diameter of the driven roller and the intermediate roller is half the diameter of the driving roller, so that the rotational speed of the driven roller is twice that of the driving roller, thereby improving working efficiency.

[0011] As a further preferred option, a ruler is provided on a slide at one end of the passive roller to precisely adjust the distance between the passive roller and the driving roller.

[0012] The beneficial effects of this utility model are:

[0013] 1. Since the active roller and the corresponding passive roller are connected at a differential speed through a chain drive mechanism, the active roller and the active roller can rotate at a differential speed in opposite directions. This enables the kneading and shelling of apricot kernels, increases the processing capacity per unit time, and does not cause material jamming even when the amount of material is increased. This can improve work efficiency and output, with hourly output increasing by 30-50%.

[0014] 2. Through the screw transmission mechanism between the sliding bearing seats at both ends of the passive roller and the frame, the distance between the passive roller and the active roller can be adjusted in real time while the passive roller is rotating, without the need to stop the machine for adjustment, thus further improving production efficiency.

[0020] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0021] like Figures 1-4 As shown, the present invention relates to an apricot kernel shelling machine, which includes a frame 1. The frame 1 includes a base frame welded from channel steel. Two support frames are symmetrically fixed on both ends of the base frame. A motor base is fixed on one side of the base frame near one end.

[0022] A drive motor 2 is mounted on the motor base of the frame 1, and a drive roller 3 and a driven roller 5 are rotatably mounted between two support frames. The output end of the drive motor 2 is connected to the adjacent drive roller 3 via a belt drive mechanism 17 for speed reduction. One end of the drive roller 3 is differentially connected to the corresponding end of the driven roller 5 via a chain drive mechanism. The chain drive mechanism includes a drive wheel 4, a driven wheel 11, and an intermediate wheel 7. The drive wheel 4 is located at one end of the drive roller 3. The intermediate wheel 7 is rotatably mounted on the frame 1 via a wheel axle and bearings and is connected to the drive wheel 4 via a chain 6. The driven wheel 11 is located at the corresponding end of the driven roller 5 and meshes with the lower half of the chain 6. The diameters of the driven wheel 11 and the intermediate wheel 7 are similar but smaller than the diameter of the drive wheel 4, which is used to achieve accelerated rotation of the driven roller 5 relative to the drive roller 3. A support block 8 is fixed on the support frame of the frame 1 corresponding to one end of the intermediate wheel 7, and the wheel axle is fixed to the support block 8 by a nut.

[0023] A pair of vertically arranged slide rails 12 are fixed on the frame 1 at both ends corresponding to the passive roller 5. The two ends of the passive roller 5 are slidably mounted between the pair of slide rails 12 via sliding bearing seats 9. A screw drive mechanism 16 is provided between the sliding bearing seats 9 and the frame 1 for real-time adjustment of the distance between the passive roller 5 and the driving roller 3. The outer end of the screw of the screw drive mechanism 16 passes through the support frame and is equipped with a handwheel. A ruler 10 is fixed on one of the slide rails at one end of the passive roller 5 to precisely adjust the distance between the passive roller 5 and the driving roller 3.

[0024] A top cover 13 is fixed to the base frame of the machine frame 1 between two support frames by screws. The top cover 13 holds the active roller 3 and the passive roller 5 in place. A feed nozzle 14 is fixed to the top cover 13. The feed nozzle 14 has a wedge-shaped cross-section and the discharge port is located above the active roller 3 and the passive roller 5 to facilitate feeding.

[0025] The upper feed inlet of the feed nozzle 14 is rectangular, and the lower discharge outlet is elongated. Multiple radially distributed material distribution strips 15 are evenly distributed inside the feed nozzle 14 to evenly disperse the input material between the active roller 3 and the passive roller 5.

[0026] The diameters of the driven roller 11 and the intermediate roller 7 are preferably half the diameter of the driving roller 4, so that the rotational speed of the driven roller 5 is twice that of the driving roller 3, thereby improving working efficiency.

[0027] During operation, the drive motor 2 is started, which drives the active roller 3 to rotate through the belt transmission mechanism. When the active roller 3 rotates, it drives the passive roller 5 to rotate in the opposite direction of the active roller 3 through the chain transmission mechanism, thus feeding the apricot kernels to be shelled into the feed nozzle 14. The apricot kernels are dispersed and slide down through the distribution plate 15. Through the active reverse differential rotation of the passive roller 5 and the active roller 3, the incoming apricot kernels can be rubbed and shelled, which can increase the processing volume per unit time. Even if the amount of material is increased, there will be no jamming. The shelled apricot kernels and apricot kernels fall out automatically.

[0028] When the specifications of the apricot kernels input change, simply rotating the handwheel drives the passive roller 5 to move horizontally via the screw transmission mechanism, thereby adjusting the gap between the passive roller 5 and the active roller 3. No machine stoppage is required for adjustment, further improving production efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
