Description

Technical Field

[0001] The utility model relates to a peeling machine, in particular to a clamping roller peeling machine with easily adjustable cutting depth, which is used for peeling off the surface black skin of cinnamon bark and belongs to the technical field of medicinal material processing machinery. Background Art

[0002] The surface black skin of the cinnamon hides collected by farmers needs to be peeled off, and the inner layer of the hides needs to be retained. After being placed in a cool place to air-dry, it is made into cinnamon bark, which is used as a spice or medicinal material. Existing cinnamon hide surface peeling machines generally use an upper conveyor belt and two lower conveyor belts arranged in a herringbone shape to clamp and convey the cinnamon hides. At the same time, a peeling mechanism is set between the two lower conveyor belts to peel the cinnamon hides during the process. Peeling machines with this type of structure require a longer clamping and conveying channel, more transmission parts, and a more complex transmission structure. It requires maintenance personnel with certain electromechanical knowledge and hands-on skills to adjust the machine to achieve good working condition. It is more suitable for making large and medium-sized equipment with higher prices for large-scale cinnamon peeling processing in factories.

[0003] For some individual farmers and small processing workshops, they have the demand for small-batch cinnamon peeling processing. Most individual users do not have much electromechanical knowledge and cannot perform complex adjustments on the peeling machine. However, the thickness of the surface black skin of different batches of cinnamon raw hides is often different, and the blade depth of the peeling machine often needs to be adjusted. Therefore, these users hope to get a small peeling machine with a simpler transmission structure, more convenient blade depth adjustment and a lower price. Utility Model Content

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A roller peeling machine with easy-to-adjust cutting depth is provided with a frame, a pair of vertical support plates arranged in parallel and spaced apart on the frame, two pairs of horizontally longitudinally arranged rollers are provided between the two vertical support plates, the right pair of rollers is the input roller consisting of the right upper roller and the right lower roller, the left pair of rollers is the output roller consisting of the left upper roller and the left lower roller, the right side of the gap between the input rollers is the feed port, and the left side of the gap between the output rollers is the discharge port; the vertices of the upper roller surfaces of the left lower roller and the right lower roller are on the same horizontal plane, and the left upper roller and the right upper roller adopt internal An elastically deformable rubber roller is provided with honeycomb column holes, and the lower left roller and the lower right roller are made of rubber rollers or metal rollers; the roller shafts at both ends of each roller body of the input clamping roller and the output clamping roller are rotatably supported on the bearing supports installed correspondingly on the two vertical support plates through bearings, and a motor and a reducer are also mounted on the frame. The output shaft of the motor is connected to the input shaft of the reducer through a belt drive assembly, and the output shaft of the reducer is connected to the roller shafts of each roller body of the input clamping roller and the output clamping roller through a chain drive assembly. The motor drives the input clamping roller and the output clamping roller to form a same-direction and same-speed clamping and conveying from right to left.

[0007] A planer assembly is installed on the inner side of the two upright support plates between the lower left roller and the lower right roller. The planer assembly is tilted to extend the planer from the lower left to the upper right. The blade head of the planer extends to the left side of the gap of the input clamping roller and the cutting edge plane of the planer is flush with the apex of the upper roller surface of the lower right roller.

[0008] An adjustment plate assembly is also set up on the right side of the planer assembly on the inner side of the two upright supporting plates; the adjustment plate assembly is provided with two front and rear annular bearing sleeves with downward-extending swing arms, and the inner rings of the two bearing sleeves are rotatably mounted on the roller shafts at the front and rear ends of the right lower roller through bearings. The outer diameter of the bearing sleeve is 1-2mm larger than the outer diameter of the right lower roller. The left outer circumferences of the two bearing sleeves are jointly spanned by a horizontal longitudinal arc-shaped adjustment plate that fits the outer circumference of the bearing sleeve, and fixing screws are provided at the front and rear ends to fix the arc-shaped adjustment plate and the two bearing sleeves into one, so that the arc-shaped adjustment plate is close to and surrounds the outer periphery of the roller surface of the right lower roller, and the arc-shaped adjustment plate is fixedly connected to the two bearing sleeves so that the arc-shaped adjustment plate is close to and surrounds the outer periphery of the roller surface of the right lower roller.

[0009] This roller-type peeling machine uses only a pair of input rollers and a pair of output rollers to clamp and convey the cinnamon hides. This can greatly simplify the transmission structure, miniaturize the entire machine, and reduce manufacturing costs, thus meeting the needs of small-batch cinnamon peeling processing. This machine can adjust the depth of the planing cut simply by adjusting the push depth of the adjustment screw, which is very convenient. In addition, the two upper rollers of this machine are elastically deformable rubber rollers with honeycomb-shaped column holes inside. When the cinnamon hides to be peeled are of varying thickness, have knots, or are concave or convex, the two upper rollers can automatically deform elastically according to the material conditions, maintaining the material's clamping, flattening, and conveying without causing material jams, thus achieving a stable peeling effect.

[0020] like Figures 1-8 As shown, the peeling machine is provided with a frame 1, above which is provided a pair of vertical support plates 2 arranged in parallel and spaced apart from each other, and between which are provided two pairs of horizontally longitudinally arranged nip rollers on the left and right sides, wherein the pair of nip rollers on the right side is an input nip roller consisting of a right upper roller 3 and a right lower roller 4, and the pair of nip rollers on the left side is an output nip roller consisting of a left upper roller 5 and a left lower roller 6, the right side of the gap between the input nip rollers is a feed port, and the left side of the gap between the output nip rollers is a discharge port; the vertices of the upper roller surfaces of the left lower roller 6 and the right lower roller 4 are on the same horizontal plane, and the left upper roller 5 and the right upper roller 3 are provided with honeycomb column holes inside. The elastically deformable rubber rollers are adopted, and the lower left roller 6 and the lower right roller 4 are made of rubber rollers or metal rollers; the roller shafts at both ends of each roller body of the input pinch roller and the output pinch roller are rotatably supported on the bearing supports 7 correspondingly installed on the two upright support plates 2 through bearings. The frame 1 is also provided with a motor 8 and a reducer 9. The output shaft of the motor 8 is connected to the input shaft of the reducer 9 through a belt drive assembly 10, and the output shaft of the reducer 9 is connected to the roller shafts of each roller body of the input pinch roller and the output pinch roller through a chain drive assembly. The motor 8 drives the input pinch roller and the output pinch roller to form a same-direction and same-speed clamping and conveying from right to left.

[0021] A planer assembly is installed on the inner side of the two upright support plates 2 between the lower left roller 6 and the lower right roller 4. The planer assembly is tilted to install a planer 11 extending from the lower left to the upper right. The blade head of the planer 11 extends to the left side of the gap of the input clamping roller and the cutting edge plane 11.1 of the planer 11 is flush with the top vertex of the upper roller surface of the lower right roller 4.

[0022] An adjustment plate assembly is also provided on the right side of the planer assembly on the inner side of the two upright support plates 2; the adjustment plate assembly is provided with two annular bearing sleeves 12 with downwardly extending swing arms 12.1 at the front and rear ends, and the inner rings of the two bearing sleeves 12 are rotatably mounted on the roller shafts at the front and rear ends of the right lower roller 4 through bearings. The outer diameter of the bearing sleeve 12 is 1-2 mm larger than the outer diameter of the right lower roller 4. The left outer circumferences of the two bearing sleeves 12 are jointly spanned by a section of arc-shaped adjustment plate 13 that extends horizontally and longitudinally and fits the outer circumference of the bearing sleeve 12, and fixing screws 28 are provided at the front and rear ends to fix the arc-shaped adjustment plate 13 and the two bearing sleeves 12 into one, so that the arc-shaped adjustment plate 13 is close to and surrounds the outer periphery of the roller surface of the right lower roller 4. The middle part of the top surface of the arc-shaped adjustment plate 13 is provided with a section extending horizontally to the left. The feeding platform 13.1 is located on the right side of the planer head 11 and is lower than the cutting edge plane 11.1 of the planer 11, thereby forming the cutting depth; the swing arm 12.1 of the bearing sleeve 12 is connected to a tension spring 14 that causes it to tilt to the right, and the vertical support plate 2 is also provided with an adjusting screw 15 that pushes from right to left on the swing arm 12.1 on the right side of the swing arm 12.1 of the bearing sleeve 12. The tension spring 14 and the adjusting screw 15 jointly position the tilting position of the swing arm 12.1. By changing the pushing depth of the adjusting screw 15, the bearing sleeve 12 is driven to rotate slightly together with the arc-shaped adjusting plate 13, and the cutting depth between the feeding platform 13.1 of the arc-shaped adjusting plate 13 and the cutting edge plane 11.1 of the planer 11 can be changed.

[0023] Furthermore, a transverse long hole 12.2 is provided on the swing arm 12.1 of the bearing sleeve 12, and a limit bolt 29 is inserted into the transverse long hole 12.2. The limit bolt 29 is fixedly connected to the vertical support plate 2, thereby limiting the left and right tilting amplitude of the swing arm 12.1.

[0024] Furthermore, an upper hanging nail 12.3 is fixed to the lower end of the swing arm 12.1 of the bearing sleeve 12, and one end of the tension spring 14 is hooked on the upper hanging nail 12.3. The inner side surface of the vertical support plate 2 or the top surface of the frame 1 is provided with a lower hanging nail 16 to the right below the bearing sleeve 12, and the other end of the tension spring 14 is hooked on the lower hanging nail 16.

[0025] Furthermore, a screw hole seat 2.1 is fixedly provided on the inner side surface of the vertical support plate 2 on the right side of the swing arm 12.1 of the bearing sleeve 12, and the adjusting screw 15 is screwed into from right to left and passes through the screw hole seat 2.1, and then the top of the rod is pushed on the swing arm 12.1 of the bearing sleeve 12.

[0026] Furthermore, a feed guide plate 17 is provided between the two upright support plates 2 on the right side of the feed port, engaging with the upper roller surface of the right lower roller 4. An intermediate guide plate 18 is provided between the two upright support plates 2, between the left lower roller 6 and the right lower roller 4. The right end of the intermediate guide plate 18 engages with the cutting edge plane 11.1 of the planer 11, and the left end of the intermediate guide plate 18 engages with the upper roller surface of the left lower roller 6. A discharge guide plate 19 is provided between the two upright support plates 2 on the left side of the discharge port, engaging with the upper roller surface of the left lower roller 6. The provision of the feed guide plate 17, the intermediate guide plate 18, and the discharge guide plate 19 can better guide material transportation and prevent material jamming.

[0027] Furthermore, the upper right roller 3 of the input clamping roller is located just above and slightly to the left of the lower right roller 4, so that the bottom end of the lower roller surface of the upper right roller 3 is located just above the blade of the planer 11. As a result, the upper right roller 3 can better press the bottom surface of the cinnamon hide onto the blade of the planer 11 and the feeding platform 13.1 of the arc-shaped adjustment plate 13 while clamping and feeding with the lower right roller 4, making the planing effect cleaner.

[0028] Furthermore, the outer diameters of the upper left roller 5 and the upper right roller 3 are the same, the outer diameters of the lower left roller 6 and the lower right roller 4 are the same, and the outer diameter of the upper left roller 5 is greater than the outer diameter of the lower left roller 6 .

[0029] Furthermore, the planer assembly is provided with a longitudinal upright seat plate 20 fixedly mounted between the two upright support plates 2, and two front and rear clamps 21 consisting of a lower support block and an upper pressure block are fixedly mounted on the upright seat plate 20. The clamping opening of the clamp 21 is inclined from the lower left to the upper right, and the planer 11 is fixedly clamped in the clamping opening of the two clamps 21.

[0030] Furthermore, the chain drive assembly is provided with a chain ring 22, a first sprocket 23 connected to the output shaft of the reducer 9, a second sprocket 24 connected to the roller shaft of the upper right roller 3, a third sprocket 25 connected to the roller shaft of the upper left roller 5, a fourth sprocket 26 connected to the roller shaft of the lower right roller 4, and a fifth sprocket 27 connected to the roller shaft of the lower left roller 6. The chain ring 22 surrounds the first sprocket 23, the second sprocket 24 and the third sprocket 25 and forms an engagement therewith, and the fourth sprocket 26 and the fifth sprocket 27 abut against the outside of the chain ring 22 and form an engagement therewith.

[0031] During operation, the peeling machine feeds soft cinnamon hides cut into specific lengths with the surface facing downwards and along their lengthwise direction through the feed port. The hides are gripped by the input and output rollers and conveyed from right to left. As they pass through the input rollers, the bent hides are flattened by the right upper roller 3, unfolding them into a flat surface. The right upper roller 3 then presses the hides along the feed platform 13.1 of the curved adjustment plate 13 toward the cutting edge of the planer 11. The cutting edge of the planer 11 scrapes away the black skin from the hides, which is then discharged downwards through the gap between the planer 11 and the curved adjustment plate 13. The cleaned hides are then gripped and conveyed to the left by the output rollers and discharged from the discharge port. During this gripping and conveying process, the right upper roller 3 and the left upper roller 5 automatically rise elastically to accommodate uneven thickness, knots, and unevenness of the hides, thereby achieving stable peeling and conveying results. When the cutting depth needs to be adjusted, by increasing the pushing depth of the adjusting screw 15, the swing arm 12.1 of the bearing sleeve 12 is pushed to the left slightly, so that the arc adjustment plate 13 can be rotated clockwise to raise the feeding platform 13.1, thereby reducing the cutting depth between the feeding platform 13.1 and the cutting edge plane 11.1 of the planer 11. Conversely, by reducing the pushing depth of the adjusting screw 15, the swing arm 12.1 of the bearing sleeve 12 is tilted to the right slightly under the action of the tension spring 14, so that the arc adjustment plate 13 can be rotated counterclockwise to lower the feeding platform 13.1, thereby increasing the cutting depth between the feeding platform 13.1 and the cutting edge plane 11.1 of the planer 11.

[0032] The above-mentioned figures are only typical embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
