Description

Technical Field

[0001] The present invention relates to the technical field of sugar production from sugarcane, and more specifically, to a pre-treatment processing device for sugar production from sugarcane. Background Art

[0002] Sugar production from sugarcane is a process of using sugarcane as raw material and finally producing products such as white granulated sugar and raw sugar through processes such as juice extraction, clarification, evaporation, crystallization, sugar separation, and drying. Before processing, pre-treatment processing such as peeling and cutting into sections is also required. However, the existing pre-treatment processing devices have the following deficiencies during the process of peeling and cutting sugarcane: the diameters of sugarcanes are different, and they are not straight but have a slightly curved angle. When entering the pre-treatment processing device and making hard contact with the blades, it is not only easy to over-scrape the sugarcane flesh and cause waste, but also easy to damage the blades, resulting in difficulty in peeling the sugarcane skin later and reducing the effect of pre-treatment processing. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a pre-treatment processing device for sugar production from sugarcane, the structure of which includes a processing main body, a feeding port, a maintenance door, and a storage box. The feeding port is arranged at the right end of the processing main body, the maintenance door is embedded in the front surface of the left end of the processing main body, the storage box is fixed at the left end of the processing main body, and a peeling mechanism is arranged inside the processing main body. The peeling mechanism is composed of a connecting plate, a sliding tube, a guiding column, a supporting rod, and a cutting tube. The connecting plate is fixed on the inner surface of the sliding tube, and the sliding tube is slidably installed outside the guiding column. The guiding column is fixed inside the processing main body. The cutting tube is fixed between the upper and lower connecting plates through the supporting rod in the middle. The cutting tube is located inside the processing main body, and a sugarcane passes through the inside of the cutting tube. A peeling knife is arranged inside the cutting tube. A swinging block is installed in the middle of the outer side of the peeling knife, and the swinging block is hinged to a torsion shaft arranged on the inner wall of the cutting tube. Four peeling knives, swinging blocks, and torsion shafts are provided, and they are annularly distributed in four directions inside the cutting tube.

[0004] As a further improvement of the present invention, a guiding block and a skin outlet are also arranged inside the cutting tube. The guiding block is arranged at an inclined angle at the inner end of the skin outlet. Under the guidance of the guiding block, the skin cut from the sugarcane is discharged along the skin outlet.

[0005] As a further improvement of the present invention, pressing wheels, hinge connecting plates, and top springs are also arranged inside the cutting tube. The pressing wheels are in contact with the surface of the sugarcane, and the axis of the pressing wheel is hinged to the inner end of the hinge connecting plate. A top spring is arranged at the outer end of the hinge connecting plate, and the top spring is fixed on the inner wall of the cutting tube. Four pressing wheels, hinge connecting plates, and top springs are provided, and they are symmetrically installed up and down.

[0006] As a further improvement of the present invention, a driving motor is also installed above the right end of the processing host, and a rotating wheel disc is arranged at the output end of the driving motor to rotate synchronously. A linkage support rod is arranged on the lower surface of the rotating wheel disc and is axially connected. A fixed disc is arranged at the left end of the linkage support rod and is axially connected. The fixed disc is fixed in the middle of the upper surface of the connecting plate. The axial connection of the linkage support rod on the lower surface of the rotating wheel disc is an eccentric axial connection, so that when the rotating wheel disc rotates, the linkage support rod is pulled to move left and right.

[0007] As a further improvement of the present invention, a cutting section cavity is also arranged at the left end of the processing host. A conveyor is installed inside the cutting section cavity. The conveyor is composed of a motor, a gear set and conveyor rollers. The output end of the motor drives the gear set to rotate, and conveyor rollers are installed at the upper end of the gear set. The gear set is composed of two meshing gears. By driving the left gear to rotate reversely by the motor, the right meshing gear rotates forward.

[0008] As a further improvement of the present invention, a telescopic hose is also arranged inside the conveyor roller. The outer end of the telescopic hose is connected with an adjusting pressing plate, and the adjusting pressing plate penetrates through the inside of the conveyor roller by means of clearance fit. Four telescopic hoses and adjusting pressing plates are provided.

[0009] As a further improvement of the present invention, a cylinder is also arranged at the top of the cutting section cavity, and a cutter is connected to the output end of the cylinder. A support plate is arranged at the left end of the cutting section cavity.

[0010] The beneficial effects of the present invention are as follows: 1. When the rotating wheel disc rotates, it pulls the linkage support rod to move left and right, thereby driving the peeling knife inside the cutting pipe to reciprocate the peeling work on the sugarcane. Elastic torsion is applied to the swing block by the torsion shaft, so that the four peeling knives swing elastically, which can automatically adjust the cutting angle, ensure that the four peeling knives can effectively peel the sugarcane with a slightly curved angle, and at the same time avoid excessive peeling of the sugarcane flesh and damage to the peeling knife; 2. By driving the left gear to rotate reversely by the motor, while the right meshing gear rotates forward, at this time, the two conveyor rollers connected to the upper end of the gear set form a state of rotating outwards in reverse to convey the sugarcane to the left end. Elastic force is applied to the adjusting pressing plate by the telescopic hose, so that the adjusting pressing plate can be telescopically adjusted outside the conveyor roller to ensure that it can squeeze and contact the surfaces of sugarcanes with different diameters for conveying work.

The guiding column 123 is fixed inside the processing main body 1. The upper and lower connecting plates 121 fix the cutting tube 125 in the middle through the supporting rod 124. The cutting tube 125 is located inside the processing main body 1. A sugarcane G penetrates through the cutting tube 125. A peeling knife 1251 is arranged inside the cutting tube 125. A swinging block 2511 is installed in the middle of the outer side of the peeling knife 1251, and the swinging block 2511 is hinged to a torsion shaft 2512 arranged on the inner wall of the cutting tube 125. A guiding block 1252 and a skin outlet 1253 are also arranged inside the cutting tube 125. The guiding block 1252 is arranged at an inclined angle at the inner end of the skin outlet 1253. Under the guiding of the guiding block 1252, the skin cut from the sugarcane G is discharged along the skin outlet 1253. A pressing wheel 1254, a hinged connecting plate 1255 and a top spring 1256 are also arranged inside the cutting tube 125. The pressing wheel 1254 abuts against the surface of the sugarcane G, and the axis of the pressing wheel 1254 is hinged to the inner end of the hinged connecting plate 1255. A top spring 1256 is arranged at the outer end of the hinged connecting plate 1255, and the top spring 1256 is fixed to the inner wall of the cutting tube 125. A driving motor 11 is also installed above the right end of the processing main body 1, and a rotating wheel disc 111 rotates synchronously at the output end of the driving motor 11.

A fixed disc 113 is arranged at the left end of the connecting support rod 112 and is connected by a shaft. The fixed disc 113 is fixed to the middle of the upper surface of the connecting plate 121.

[0022] As a further improvement of the present invention, a cutting section cavity 13 is also arranged at the left end of the processing main body 1. A conveyor 14 is installed inside the cutting section cavity 13. The conveyor 14 is composed of a motor 141, a gear set 142 and a conveyor roller 143. The output end of the motor 141 drives the gear set 142 to rotate, and a conveyor roller 143 is installed at the upper end of the gear set 142. A telescopic hose 1431 is also arranged inside the conveyor roller 143. The outer end of the telescopic hose 1431 is connected to an adjusting pressing plate 1432, and the adjusting pressing plate 1432 penetrates through the conveyor roller 143 by means of clearance fit. A cylinder 131 is also arranged at the top of the cutting section cavity 13, and a cutting knife 132 is connected to the output end of the cylinder 131. A support plate 133 is arranged at the left end of the cutting section cavity 13; In the present invention, sugarcane G is guided from the feed inlet 2 and extends into the cutting tube 125 of the peeling mechanism 12. The driving motor 11 is started to drive the rotating wheel disc 111 to rotate. When the rotating wheel disc 111 rotates, it pulls the linkage rod 112 to move left and right, thereby driving the peeling knife 1251 inside the cutting tube 125 to perform reciprocating peeling work on the sugarcane G. An elastic torsion force is applied to the swing block 2511 through the torsion shaft 2512, causing the four peeling knives 1251 to swing elastically, enabling automatic adjustment of the cutting angle, ensuring that the four peeling knives 1251 can effectively peel the sugarcane G with a slightly curved angle, while avoiding excessive peeling of the sugarcane flesh and damage to the peeling knife 1251. During the peeling process, with the cooperation of the top spring 1256 and the hinge connecting plate 1255, the pressing wheel 1254 is adjusted in the cutting tube 125, and can slide against the surface of the sugarcane G with different diameters and a slightly curved angle, improving the smoothness of the sugarcane G during the process of moving and peeling inside the cutting tube 125. The peeled sugarcane G extends into the cutting chamber 13 under the conveyance of the conveying roller 143. One end of the sugarcane G is supported by the support plate 133, making the sugarcane G directly below the cutter 132. By starting the cylinder 131 to drive the cutter 132 to move up and down, the sugarcane G is cut into segments, and the bottom of the cutting chamber 13 is an inclined plane, guiding the cut sugarcane G into the storage box 4 for storage.

[0023] In a preferred technical solution, there are four peeling knives 1251, swing blocks 2511 and torsion shafts 2512, and they are annularly distributed in four directions inside the cutting tube 125. An elastic torsion force is applied to the swing block 2511 through the torsion shaft 2512, causing the four peeling knives 1251 to swing elastically, enabling automatic adjustment of the cutting angle, ensuring that the four peeling knives 1251 can effectively peel the sugarcane G with a slightly curved angle, while avoiding excessive peeling of the sugarcane flesh; In a preferred technical solution, there are four pressing wheels 1254, hinge connecting plates 1255 and top springs 1256, and they are symmetrically installed up and down. With the cooperation of the top spring 1256 and the hinge connecting plate 1255, the pressing wheel 1254 is adjusted in the cutting tube 125, and can slide against the surface of the sugarcane G with different diameters and a slightly curved angle, improving the smoothness of the sugarcane G during the process of moving and peeling; In a preferred technical solution, the shaft connection of the linkage rod 112 on the lower surface of the rotating wheel disc 111 is an eccentric shaft connection, so that when the rotating wheel disc 111 rotates, it pulls the linkage rod 112 to move left and right, thereby driving the whole peeling mechanism 12 to move left and right, realizing the reciprocating peeling work of the peeling mechanism 12 on the sugarcane G, and improving the peeling effect on the sugarcane G; A preferred technical solution is that the gear set 142 is composed of two meshing gears. The left gear is driven by the motor 141 to reverse, while the right meshing gear rotates forward. At this time, the two conveyor rollers 143 connected to the upper end of the gear set 142 form a state of reversing outwards to convey the sugarcane G to the left end, realizing the movement and peeling of the sugarcane G, and the end of the peeled sugarcane G enters the cutting cavity 13; A preferred technical solution is that there are four telescopic hoses 1431 and adjusting pressing plates 1432 respectively. The telescopic hose 1431 applies elastic force to the adjusting pressing plate 1432, so that the adjusting pressing plate 1432 can be telescopically adjusted outside the conveyor roller 143, ensuring that the surfaces of sugarcanes G with different diameters can be squeezed and contacted for conveying work; A preferred technical solution is that the support plate 133 supports one end of the sugarcane G, so that the sugarcane G is directly below the cutter 132. By starting the cylinder 131 to drive the cutter 132 to move up and down, the sugarcane G is cut into sections, and the bottom of the cutting cavity 13 is an inclined surface to guide and discharge the cut sugarcane G into the storage box 4 for storage. Using the technical solution of the present invention, or those skilled in the art being inspired by the technical solution of the present invention to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present invention.
