Description

Technical Field

[0001] The present invention relates to a peeling device, specifically a peeling device for grapevines. Background Art

[0002] Vine is a tough, smooth and elastic natural weaving material, which is widely used in manufacturing rattan products such as rattan chairs, rattan beds, rattan bags, etc. Rattan products have the characteristics of beautiful shape and simple nature, and are highly favored by consumers.

[0003] Before making rattan weaving, the outer skin of the vine needs to be evenly peeled off. Currently, for vine peeling, usually, a worker uses a blade to peel a section at one end of the vine, and then peels off the whole vine skin by hand. However, the cost of vines is relatively high, and the manual method will cause the width of the peeled vine skin to be uneven each time, resulting in unqualified quality. Moreover, peeling the vine skin by hand easily causes damage to the vine skin, resulting in losses. Summary of the Invention

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-8, the present invention provides a technical solution: a grapevine peeling and skinning device, including a base 1 and a first substrate 2 and a second substrate 3 arranged on both sides of the top of the base 1. A cylinder 4 is provided on the first substrate 2, and a motor 5 is provided on the second substrate 3. The output end of the cylinder 4 is rotatably connected to a positioning pressing plate 6, and the output end of the motor 5 is fixed with a spiked end 7. The spiked end 7 is arranged opposite to the positioning pressing plate 6. One end of the top close to the second substrate 3 is provided with a fixed side plate 8, and the fixed side plates 8 are symmetrically arranged on both sides of the second substrate 3. A centering mechanism 9 is arranged between the two fixed side plates 8 to align the center of one end of the grapevine with the spiked end 7. A peeling mechanism 10 for peeling the skin at one end of the grapevine is also symmetrically arranged between the two groups of fixed side plates 8. The peeling mechanism 10 includes a main board 101, a U-shaped insertion knife 102 and a peeling metal sheet 103. A strip-shaped groove 11 is provided at the blade of the U-shaped insertion knife 102 for one end of the peeling metal sheet 103 to extend into the groove of the U-shaped insertion knife 102. A driving component is arranged on the base 1 to drive the two peeling mechanisms 10 to move towards each other or away from each other. A feeding board component for driving the peeling metal sheet 103 to perform peeling is also arranged on the main board 101.

[0021] As can be seen from the above description: Before peeling the grapevine, the center of one end of the grapevine is aligned with the spiked end 7 through the centering mechanism 9. After one end of the grapevine is aligned with the spiked end 7, the cylinder 4 drives the positioning pressing plate 6 to move towards the spiked end 7 and press the other end of the grapevine, thus completing the fixation of the grapevine. The centering mechanism 9 is arranged on one side close to the second substrate 3. After the grapevine is centered by the centering mechanism 9, it can be positioned with the spiked end 7 faster. Due to the certain curvature of the grapevine, after the center of one end of the grapevine is positioned with the spiked end 7, the end of the grapevine located at the positioning pressing plate 6 will deviate from the position directly opposite to the spiked end 7. Therefore, the positioning of the other end of the grapevine adopts the positioning pressing plate 6. The surface of the positioning pressing plate 6 is evenly and densely arranged with thorns 51. The positioning pressing plate 6 has a certain area, which can ensure that the end of the grapevine far from the spiked end 7 is pressed and fixed.

[0022] Specifically, a base block 12 is arranged between the two fixed side plates 8. There are multiple groups of centering mechanisms 9 arranged along the axial direction of the spiked end 7. The centering mechanism 9 includes a centering plate 91 and a pressure spring 92. The centering plates 91 are evenly arranged in multiple groups along the axial direction of the spiked end 7 and are all slidably arranged in the base block 12 along the radial direction of the spiked end 7. A plate groove 13 for the centering plate 91 to slide is arranged in the base block 12. The pressure spring 92 is fixed on the bottom inner wall of the chute and the other end is fixed on the centering plate 91. An arc-shaped opening 14 is arranged at one end of each group of centering plates 91 away from the chute. The arc-shaped openings 14 of multiple groups of centering plates 91 form a hole-shaped structure for the vine to be inserted in the initial state.

[0023] As can be seen from the above description: The arc-shaped openings 14 in the multi-group centering mechanism 9 are all coaxially arranged with the spike end 7. The multi-group centering mechanism 9 can center multiple cross-sectional positions of the grapevine. After the multi-group centering mechanism 9 centers multiple positions of the grapevine, the grapevine is pushed towards the spike end 7, and the spike end 7 is inserted into the end of the grapevine for preliminary positioning.

[0024] Specifically, a cylindrical groove 15 is further provided in the base block 12. The depth of the cylindrical groove 15 is less than the depth of the plate groove 13. The plate groove 13 is located within the area of the cylindrical groove 15. An annular plate 16 is rotatably provided in the cylindrical groove 15. An inner ring groove 17 is provided on the inner peripheral wall of the annular plate 16. One end of each centering plate 91 away from the arc-shaped opening 14 is provided with an extension rod 18 extending into the inner ring groove 17. Short shafts 19 are provided on the front and rear sides of the extension rod 18. An arc-shaped groove 20 for the short shafts 19 to slide is provided on the annular plate 16. The compression spring 92 is sleeved on the extension rod 18.

[0025] As can be seen from the above description: Through the cooperation with the annular plate 16, the centering plates 91 in multiple groups on the circumference can be ensured to move radially outward or radially inward simultaneously, achieving a better centering effect on the grapevine.

[0026] Specifically, an L-shaped rod 21 is provided at the top of the main board 101. A fixed box 22 is provided at the end of the L-shaped rod 21 away from the main board 101. The sheet feeding assembly includes a sheet feeding motor 54 and a winding roller 23. The sheet feeding motor 54 is fixed to the outer end of the fixed box 22. A long shaft is fixed to the output end of the sheet feeding motor 54. The long shaft is rotatably arranged in the fixed box 22. The winding roller 23 is coaxially arranged on the long rod and is used for winding the peeling metal sheet 103. A roller storage area for placing the winding roller 23 is provided in the fixed box 22. An extension slot 24 for the peeling metal sheet 103 to extend out is provided at the bottom of the roller storage area.

[0027] As can be seen from the above description: After the U-shaped insertion knife 102 is inserted into the grapevine to a certain depth, the strip-shaped groove 11 is located at the boundary between the vine skin and the vine body of the grapevine or a deeper position (the boundary is better). The sheet feeding motor 54 drives the winding roller 23 to rotate, and the peeling metal sheet 103 is extended between the two side blades of the U-shaped insertion knife 102, thereby peeling off the vine skin of the grapevine.

[0028] Specifically, one end of the peeling metal sheet 103 is fixed to the winding roller 23, and the other end initially extends out from the extension slot 24 and is located in the strip-shaped groove 11 of the upper side blade of the U-shaped insertion knife 102. A slot 25 for the end of the peeling metal sheet 103 to be inserted is provided on the lower side blade of the U-shaped insertion knife 102.

[0029] As can be seen from the above description: After the end of the peeling metal sheet 103 enters the slot 25, the peeling of the vine skin of a certain width of the grapevine is completed.

[0030] Specifically, a vine pressing airbag 26 is provided in the groove of the U-shaped inserting knife 102.

[0031] As can be seen from the above description: when the U-shaped inserting knife 102 is inserted into the grapevine, the vine pressing airbag 26 between the two side blades of the U-shaped inserting knife 102 will press tightly against the outer surface of the grapevine. During the process of the peeling metal sheet 103 separating the grapevine bark from the vine body, the outer surface of the grapevine is pressed tightly, making it difficult for the peeling metal sheet 103 to penetrate through the grapevine bark during the peeling process, and enabling the peeling metal sheet 103 to more stably cut and separate along the boundary between the grapevine bark and the vine body.

[0032] Specifically, the driving assembly includes a driving motor 27, a first shaft body 28, a second shaft body 29, a third shaft body 30 and a screw sleeve 31. A connecting plate 32 is connected between the two fixed side plates 8. On both sides of the bottom of the connecting plate 32, fixing plates 33 are symmetrically provided. There are two groups of the first shaft body 28, which are respectively rotatably arranged on the two fixing plates 33. There are two groups of the second shaft body 29 corresponding to the first shaft body 28, which are respectively rotatably arranged on the two fixed side plates 8. The third shaft body 30 is slidably arranged on the side plate and one end thereof is fixed to the main board 101. The screw sleeve 31 is rotatably arranged in the fixed side plate 8 and sleeved outside the third shaft body 30. The third shaft body 30 is threadedly connected with the screw sleeve 31. The driving motor 27 is fixed on the fixing plate 33 and a first bevel gear 34 is fixed to the output end thereof. On one end of the two first shaft bodies 28 close to each other, a second bevel gear 35 meshing with the first bevel gear 34 is provided. A conical tooth part 38 is fixed on the outer circumference of the screw sleeve 31. A fifth bevel gear 55 meshing with the conical tooth part 38 is provided at the bottom of the second shaft body 29. A fourth bevel gear 37 is provided at the top of the second shaft body 29. A third bevel gear 36 meshing with the fourth bevel gear 37 is provided at one end of the first shaft body 28 away from the second bevel gear 35.

[0033] As can be seen from the above description: in the above way, the two peeling mechanisms 10 move towards each other or away from each other at the same time, so that the forces on both sides during the grapevine peeling process are balanced to a certain extent.

[0034] Specifically, an anti-rotation rod 39 is provided at one end of the third shaft body 30 away from the main board 101. A side extension rod 40 is provided on the back of the fixed side plate 8. An anti-rotation groove 41 for the anti-rotation rod 39 to slide is provided in the side extension rod 40.

[0035] As can be seen from the above description: during the process of driving the peeling mechanism 10 to move, it will not rotate through the cooperation of the anti-rotation rod 39 and the anti-rotation groove 41.

[0036] Specifically, the first shaft body 28 includes an outer shaft 281 and an inner shaft 282. An axial groove 42 for the inner shaft 282 to rotate is provided inside the outer shaft 281. Both ends of the inner shaft 282 are rotatably connected to the outer shaft 281 through bearings. Ball grooves 43 are provided on the inner wall of the axial groove 42. A plurality of groups of pre-tightening rods 44 are evenly provided on the inner shaft 282. Radial grooves 45 for the pre-tightening rods 44 to slide radially are provided on the inner shaft 282. Tension springs 46 are provided in the radial grooves 45. The outer ends of the pre-tightening rods 44 are provided with ball head ends adapted to the ball grooves 43.

[0037] As can be seen from the above description: In order to avoid the situation that the depths of the two U-shaped cutting knives 102 inserted into the grapevine are different due to the misalignment of the center of the grapevine with the spike end 7, through the first shaft body 28 composed of the inner shaft 282 and the outer shaft 281, after one side of the U-shaped cutting knife 102 is inserted into the grapevine to a certain depth, when the first bevel gear 34 drives the second bevel gear 35 to rotate, the inner shaft 282 and the outer shaft 281 will rotate relative to each other until the relative rotation of the inner shaft 282 and the outer shaft 281 on both sides indicates that the two U-shaped cutting knives 102 are inserted into the grapevine to the same depth.

[0038] Specifically, seats grooves 47 for the U-shaped cutting knives 102 to slide are provided at one ends of the two main boards 101 close to each other. Limit rods 48 are provided on both sides of the U-shaped cutting knives 102. Limit grooves 49 for the limit rods 48 to slide are provided in the seats grooves 47. Switches 56 for starting the film feeding motor 54 are provided on the inner walls of the seats grooves 47. Support springs 50 for supporting the U-shaped cutting knives 102 are provided in the seats grooves 47.

[0039] As can be seen from the above description: After the two U-shaped cutting knives 102 are both inserted into the grapevine to a certain depth, the U-shaped sockets will move the same distance into the seats grooves 47 and contact the switches 56 simultaneously. At this time, the film feeding motor 54 is started, avoiding separately controlling the two film feeding motors 54 and improving convenience.

[0040] Please refer to Figure 1-8 As shown in the following, a specific embodiment of the present invention is: When the device is in use, the present invention relates to a grapevine peeling device, which is mainly used to solve problems such as uneven width and easy breakage of the vine skin caused by manual peeling.

[0041] Refer to Figure 1 、 2, 5, 8. The device includes a base 1. On both sides of the top of the base 1, a first substrate 2 and a second substrate 3 are fixed. A cylinder 4 is installed on the first substrate 2, and its output end is rotatably connected to a positioning pressing plate 6. The rotation mode of the positioning pressing plate 6 is as follows: a T-shaped turntable 52 is provided at one end of the positioning pressing plate 6 close to the cylinder 4, and a T-shaped groove 53 for the T-shaped turntable 52 to rotate is provided at the output end of the cylinder 4; a motor 5 is installed on the second substrate 3, and a spiked end 7 opposite to the positioning pressing plate 6 is fixed at its output end. Two groups of fixed side plates 8 are symmetrically arranged at one end of the top of the base 1 close to the second substrate 3. A centering mechanism 9 and a peeling mechanism 10 are provided between the two side plates. The centering mechanism 9 is used to align the center of one end of the grapevine with the spiked end 7. In order to better drive the grapevine to rotate when the spiked end 7 rotates, insertion pieces 56 are provided on the surface of the spiked end 7, so as to prevent the cylindrical body of the spiked end 7 from driving the grapevine to rotate; the peeling mechanism 10 is symmetrically distributed between the two groups of fixed side plates 8 and is used to peel the epidermis of the grapevine. The peeling mechanism 10 includes a main board 101, a U-shaped insertion knife 102 and a peeling metal sheet 103. A strip-shaped groove 11 is opened at the blade of the U-shaped insertion knife 102 for one end of the peeling metal sheet 103 to extend into its groove. A driving component for driving the two peeling mechanisms 10 to move towards or away from each other is provided on the base 1, and a feeding board component for driving the peeling metal sheet 103 to peel is also provided on the main board 101.

[0042] Refer to Figure 2 , 3 , the specific structure of the centering mechanism 9 is as shown in the figure: a base block 12 is fixed between the two fixed side plates 8. A plurality of groups of centering plates 91 are arranged axially along the spiked end 7 in the base block 12. Each group of centering plates 91 is slidably arranged in a plate groove 13 of the base block 12 along the radial direction of the spiked end 7. The inner wall of the bottom of the plate groove 13 is connected to the centering plate 91 through a compression spring 92. An arc-shaped opening 14 is provided at one end of the centering plate 91 away from the plate groove 13. A plurality of arc-shaped openings 14 form a positioning hole for the vine to be inserted in the initial state. Among them, a slope can be provided at the end face of the positioning plate where the grapevine is inserted, which is located at the positioning hole, to facilitate the insertion of the grapevine. To optimize the centering adjustment, a cylindrical groove 15 with a depth less than that of the plate groove 13 is opened in the base block 12, and an annular plate 16 is rotatably arranged in the groove. An inner ring groove 17 is provided on the inner peripheral wall of the annular plate 16. An extension rod 18 extends from one end of the centering plate 91 away from the positioning hole and extends into the inner ring groove 17. The short shafts 19 on both sides of the extension rod 18 are clamped into the arc-shaped grooves 20 of the annular plate 16, and the compression spring 92 is sleeved outside the extension rod 18. When the vine is inserted, it pushes the centering plate 91 to slide radially, and the compression spring 92 provides an adaptive pressing force to ensure that the center of the vine is aligned with the spiked end 7.

[0043] Refer to Figure 2 , 3, 6, 7, the working process of the peeling mechanism 10 is as follows: The U-shaped insertion knife 102 is slidably installed in the seat groove 47 of the main board 101 through the two-sided limit rods 48.

One end of the peeling metal sheet 103 is wound around the winding roller 23, and the other end extends out from the extension slot 24 at the bottom of the fixed box 22 and is initially embedded in the strip groove 11 on the upper side blade of the U-shaped insertion knife 102. The lower side blade of the U-shaped insertion knife 102 is provided with a slot 25 for the end of the peeling metal sheet 103 to be inserted. When the U-shaped insertion knife 102 is inserted into the grapevine to a certain depth, the sheet feeding motor 54 drives the winding roller 23 to rotate, pushing the peeling metal sheet 103 to move along the strip groove 11 towards the slot 25, so as to peel the vine skin between the two blades of the U-shaped insertion knife 102. In addition, a pressing vine airbag 26 is provided in the groove of the U-shaped insertion knife 102 to press against the surface of the vine skin to prevent the peeling metal sheet 103 from piercing through the vine skin during cutting. It should be noted that: the strip groove 11 has a certain angle, and the strip groove 11 faces the tangent direction of the boundary between the grapevine skin and the vine body, which is convenient for the peeling metal sheet 103 to cut in. In addition, the distance between the strip groove 11 and the airbag is equal to the thickness dimension of the grapevine skin, which is the best, so as to ensure that when the airbag presses against the outer surface of the grapevine, the strip groove 11 is located at the boundary between the grapevine skin and the vine body. Switches 56 are arranged in the seat grooves 47 of the two main boards 101. After the two U-shaped insertion knives 102 are inserted into the grapevine to a certain depth, the U-shaped socket will move the same distance into the seat groove 47 and contact the switch 56 at the same time. At this time, the sheet feeding motor 54 is started, avoiding separately controlling the two sheet feeding motors 54 on both sides, which improves convenience. Among them, each time the sheet feeding motor 54 is started, a forward and reverse rotation will be formed, that is, the stroke of the end of the peeling metal sheet 103 from the strip groove 11 to the slot 25 position and then back to the strip groove 11 position.

[0044] Refer to Figure 2 , 3, 5. A connecting plate 32 is provided between the two fixed side plates 8 on both sides, and fixing plates 33 are symmetrically arranged at its bottom. Two groups of first shafts 28 are respectively rotatably installed on the fixing plates 33, and two groups of second shafts 29 are rotatably installed on the fixed side plates 8. A third shaft 30 is slidably arranged in the fixed side plate 8, with one end fixed to the main board 101 and the other end provided with an anti-rotation rod 39; an anti-rotation groove 41 is formed in the side extension rod 40 on the back of the fixed side plate 8 for the anti-rotation rod 39 to slide, restricting the rotation of the third shaft 30. A screw sleeve 31 is rotatably embedded in the fixed side plate 8 and sleeved on the third shaft 30, and the screw sleeve 31 is in threaded cooperation with the third shaft 30. The driving motor 27 is fixed to the fixing plate 33, and the first bevel gear 34 at its output end meshes with the second bevel gear 35 at the end of the first shaft 28. A third bevel gear 36 is provided at the other end of the first shaft 28, which meshes with the fourth bevel gear 37 at the top of the second shaft 29; the fifth bevel gear 55 at the bottom of the second shaft 29 meshes with the bevel gear portion 38 on the outer periphery of the screw sleeve 31. The driving motor 27 drives the screw sleeve 31 to rotate through the bevel gears, driving the third shaft 30 to axially move, so as to drive the peeling mechanisms 10 on both sides to approach or move away from the grapevine synchronously. The first shaft 28 is designed as a buffer structure, including an outer shaft 281 and an inner shaft 282. The inner shaft 282 is radially slidably arranged in the shaft groove 42 of the outer shaft 281 through a pre-tightening rod 44, and the ball head end at the end of the pre-tightening rod 44 is tightly pressed by a tension spring 46 and clamped into the ball groove 43 of the outer shaft 281. When the resistance of the U-shaped cutter 102 inserted into the vine is too large, the inner shaft 282 and the outer shaft 281 rotate relative to each other, preventing the U-shaped cutter 102 from being inserted too deeply into the grapevine. After a section of vine bark is peeled off from the grapevine by the peeling mechanisms 10 on both sides, the driving motor 27 is reversed, and then the peeling mechanisms 10 on both sides are reset, and the motor 5 is started to drive the grapevine to rotate by an angle, so that the peeling mechanism 10 peels off the next section of vine bark. It should be noted that: through the cooperation of multiple groups of bevel gears, the screw sleeves 31 on both sides will rotate in opposite directions, so the thread directions of the third shafts 30 on both sides are set in the opposite direction to ensure that the third shafts 30 on both sides move in the direction of approaching or moving away from each other when the driving motor 27 is started.

[0045] Refer to Figure 1-8, the working process of the device is as follows: One end of the grapevine is placed in the positioning hole of the centering mechanism 9, the cylinder 4 pushes the positioning pressing plate 6 to press the end of the vine, and the motor 5 drives the spiked end 7 to pierce into the center of the vine for fixation. The driving assembly pushes the peeling mechanisms 10 on both sides to move towards each other, so that the U-shaped insertion knives 102 are inserted into the epidermis of the vine. When the U-shaped insertion knives 102 on both sides are pressed and retracted, the switches 56 on the inner walls of the seat grooves 47 on both sides are triggered to start the film feeding motor 54, and the peeling metal sheet 103 moves from the strip-shaped groove 11 to the slot 25 to peel off the vine skin between the two blades of the U-shaped insertion knife 102. The vine pressing airbag 26 presses the vine skin during the insertion of the peeling metal sheet 103 to ensure that the peeling metal sheet 103 cuts along the skin-core interface. After the peeling is completed, the driving assembly drives the peeling mechanism 10 to reset, starts the motor 5, drives the grapevine to rotate by an angle, and then repeats the above method to peel the grapevine skin once again until all the grapevines at one end of the grapevine for one week are peeled off. Finally, the cylinder 4 drives the positioning pressing plate 6 to move towards the side away from the spiked end 7, takes down the grapevine, and then manually peels off the vine skin at one end of the grapevine to tear off the whole vine skin.
