Description

Technical Field

[0001] The invention relates to the field of celtis sinensis peeling, and in particular to an automatic celtis sinensis peeling machine. Background Art

[0002] Xuan paper made from the bark of Chinese euphorbia pulcherrima has strong adsorption, is not easy to deform, is resistant to aging, is resistant to insect infestation, and has a long lifespan, making the paper thin, light, soft, tough, fine, and white. It helps calligraphers and painters achieve a special style of varying shades and increasing ink absorption when creating calligraphy and painting. Since the Ming Dynasty, all the famous calligraphy and paintings, historical documents, etc., which were written, printed, and copied on Xuan paper, are intact and have been passed down to this day. Therefore, Xuan paper has always been famous at home and abroad for its reputation of "paper lasting a thousand years and ink rhyme ever-changing". All of this is inseparable from the fact that the raw material of Xuan paper is mainly the bark of Chinese euphorbia pulcherrima.

[0003] The traditional method of peeling the Chinese cedarwood mainly relies on manual labor, which is inefficient, labor-intensive, and has great harm to the hands and skin. If the Chinese cedarwood is not peeled in time, it will affect the quality of Xuan paper and lead to a waste of resources. In addition, manual peeling is difficult to ensure a high peeling rate and a low breakage rate of the green peel, and during the peak harvest, it is difficult to find labor and the cost is high. The invention of the Chinese cedarwood peeling machine can significantly improve the peeling efficiency, reduce labor intensity, and reduce dependence on manual labor. Mechanized peeling can ensure a high peeling rate and a low breakage rate of the green peel, improve the quality of the Chinese cedarwood bark, and thus improve the quality of Xuan paper. In addition, the peeling machine can work around the clock, greatly improving production efficiency and reducing production costs. Summary of the invention

[0009] The peeling module includes a cutting module, a tearing module and a third frame.

[0010] The knife module comprises a knife disc 31, a hydraulic cylinder 32, and a knife 33. The knife disc 31 is fixedly mounted on the front end of the frame 3. The cylinder bodies of the hydraulic cylinders 32 are mounted on the inner side of the knife disc 3. Each knife is fixedly mounted on the piston rod of the hydraulic cylinder 32. The knifes are arranged in the circumference of the pine tree. When the pine tree moves axially, each knife cuts a slit parallel to the axial direction of the pine tree. The depth of the slit in the radial direction of the pine tree is not less than the thickness of the bark of the pine tree. The slits divide the bark of the pine tree into a plurality of strips.

[0011] The tearing module comprises a No. 2 cutter disc 61, a No. 3 hydraulic cylinder 63, a cutter 69, an upper clamping plate 67, and a No. 4 hydraulic cylinder 65; a plurality of cutters are arranged in the circumference of the Chinese hollywood, and the cutter 69 comprises a cutter body 691 and a blade 692 extending along the chord direction of the Chinese hollywood; the No. 2 cutter disc is mounted at the rear end of the No. 3 frame, and the cylinder bodies of a plurality of No. 3 hydraulic cylinders are mounted on the No. 2 cutter disc, and the cutter body of each cutter is directly or indirectly connected to the piston rod of the No. 3 hydraulic cylinder, and the No. 3 hydraulic cylinder is used to drive the cutter to move in the radial direction of the Chinese hollywood; the two ends of the No. 4 hydraulic cylinder are respectively hinged to the cutter body and the front part of the upper clamping plate, and the rear part of the upper clamping plate is hinged to the cutter body; in the radial direction of the Chinese hollywood, the blade is closer to the center of the Chinese hollywood than the upper clamping plate;

[0012] The cutting knife 69 and the scratching knife 33 are arranged alternately in the circumferential direction of the qingtan;

[0013] When the bark of the Chinese zelkova tree is cut into strips and moves axially from front to back, the blade of each cutter cuts into the end of the Chinese zelkova tree and extends between the end of the bark strip and the trunk; then the No. 4 hydraulic cylinder is activated, driving the front part of the upper plywood to flip downward, clamping the end of the bark strip between the blade and the upper plywood; then the No. 3 hydraulic cylinder drives the cutter and the upper plywood away from the Chinese zelkova tree in the radial direction, and the Chinese zelkova tree continues to move backward axially, and the bark strips are gradually separated from the trunk.

[0014] In the above-mentioned automatic peeling machine for Chinese golden sandalwood, two guide plates 62 are symmetrically arranged on both sides of each cutting knife 69, the guide plates 62 are fixedly connected to the No. 2 knife disc 61, the rear ends of the No. 2 connecting blocks 68 are fixed on both sides of the knife body, the front ends of the No. 2 connecting blocks 68 are connected to the cam follower 66, the cam follower 66 is slidably installed in the slots opened on the guide plates 62 and extending in the radial direction of the golden sandalwood, and the baffle plate 64 is fixed between the rear ends of the two guide plates 62; a transition plate 693 extending backward is fixed to the rear side of the knife body, in the radial direction of the golden sandalwood, the transition plate is closer to the center of the golden sandalwood than the baffle plate, and the transition plate is hinged to the piston rod of the No. 3 hydraulic cylinder 63;

[0015] When the No. 3 hydraulic cylinder 63 drives the transition plate, the cutter 69 and the No. 2 connecting block 68 to move along the radial direction of the Chinese holly toward the center of the Chinese holly, the knife body swings backward around the cam follower 66 relative to the guide plate 62, and when the rear side of the knife body contacts the front side of the baffle 64, the blade extends in the axial direction parallel to the Chinese holly, and the cam follower 66 slides in the groove on the guide plate 62; when the No. 3 hydraulic cylinder 63 drives the transition plate, the cutter 69 and the No. 2 connecting block 68 to move along the radial direction of the Chinese holly away from the center of the Chinese holly, the knife body swings forward around the cam follower 66 relative to the guide plate 62, and the blade extends in an inclined direction with a certain angle to the axial direction of the Chinese holly, and the cam follower 66 slides in the groove on the guide plate 62.

[0016] In the automatic peeling machine for Chinese cedarwood, the front end of the upper splint extends forward beyond the blade in the axial direction, and the upper splint and the blade are parallel in the axial direction of the Chinese cedarwood. When the Chinese cedarwood whose bark is cut into strips moves axially from front to back until the end face of the Chinese cedarwood exceeds the front end of the upper splint 67 but does not reach the front end of the blade, the Chinese cedarwood stops moving. Then, the No. 3 hydraulic cylinder 63 drives the transition plate, the cutting knife 69, and the upper splint 67 to move toward the center of the Chinese cedarwood along the radial direction of the Chinese cedarwood. The knife body swings backward relative to the guide plate 62 around the cam follower 66, and the rear side of the knife body contacts the front side of the baffle plate 64 and slides relative to the baffle plate. When the upper splint contacts the outer periphery of the Chinese cedarwood, the No. 3 hydraulic cylinder 63 stops. The blade of the cutter is extended in parallel to the axial direction of the Chinese pine; then, the Chinese pine moves axially from front to back, and the blade of the cutter cuts into the end of the Chinese pine, and gradually extends between the end of the strip bark and the trunk. Then the No. 4 hydraulic cylinder 65 is actuated to drive the front part of the upper clamping plate 67 to flip downward, clamping the end of the strip bark between the blade and the upper clamping plate 67. Then the No. 3 hydraulic cylinder 63 drives the cutter to move away from the Chinese pine in the radial direction, and the cutter body swings forward relative to the guide plate 62 around the cam follower 66. The blade extends in an inclined direction with a certain angle to the axial direction of the Chinese pine. As the Chinese pine moves axially, the strip bark is gradually separated from the trunk.

[0017] After the bark strips are completely separated from the trunk, the pinewood stops moving axially, and the No. 4 hydraulic cylinder 65 is actuated to drive the front part of the upper clamping plate 67 to flip upward, loosening the ends of the clamped bark strips, and the bark strips fall freely.
