Description

Technical Field

[0001] The present invention relates to the technical equipment field of lacquer liquid collection, and specifically relates to an automatic lacquer cutting device. Background Art

[0002] The lacquer tree can produce lacquer liquid, which will gradually harden after oxidation in the air to form a firm and durable coating. The existing method of collecting lacquer liquid is usually that a person holds a knife to cut a V-shaped or inclined incision on the lacquer tree, inserts a V-shaped iron sheet at the incision to divert the lacquer liquid, ties a receiving bottle to the lacquer tree, and places the iron sheet at the bottle mouth of the receiving bottle to slowly flow the lacquer liquid into the bottle. However, the lacquer tree has a certain height, and the incisions are generally made at intervals along the height direction of the lacquer tree. When cutting at a high position of the lacquer tree, it may be necessary for a person to hold a knife and climb a ladder to the corresponding height position of the lacquer tree to cut an incision to collect the lacquer. The risk factor during the process of the person climbing the ladder to make the incision is relatively high, and the person holding the knife to cut the incision increases the labor intensity of the person. In addition, when a person holds a knife to cut, it is inevitable to contact some lacquer liquid. Since the urushiol in the lacquer liquid is irritating to the human body, contacting the skin may cause an allergic reaction. In order to prevent contact with the lacquer liquid, it is usually required that a person wear protective clothing when collecting lacquer liquid with a knife, which increases the cost expenditure.

Specific embodiments

[0022] The technical solution of the present invention will be further elaborated in detail below in conjunction with specific embodiments. For parts not described in detail in the following embodiments of the present invention, such as the claw hand is opened or closed by a robotic arm, the cutting knife moves through a robotic arm to cut an incision, and the collecting ball cavity moves to the incision through a robotic arm hinge, and what components the transmission system includes, etc., should all be understood as the prior art known or should be known to those skilled in the art.

[0023] As Figure 1 shown, an automatic lacquer cutting device includes a fixed hoop 1 composed of segments, an iris opening and closing fixing mechanism 2, a cutting and harvesting mechanism 3, and multiple flight control mechanisms 5. The fixed hoop 1 is formed by surrounding four arc rings 101 end to end. A cavity capable of accommodating a lacquer tree is formed inside the fixed hoop 1 so that the fixed hoop 1 is sleeved on the outer periphery of the lacquer tree.

[0024] Two of the four arc rings 101 are fixedly connected by clamping through a clamping member (not shown in the figure). A clamping groove is provided at the right end of the left arc ring 101, and a clamping block capable of being clamped and matched with the clamping groove is provided at the left end of the corresponding right arc ring 101. The right arc ring 101 is clamped and connected by the clamping block being inserted into the clamping groove of the left arc ring 101. The other two arc rings 101 are hingedly and rotationally connected through hinges 102 at opposite ends, and the other ends of the two arc rings 101 are respectively rotationally connected to the adjacent arc rings 101 through hinges 102.

[0025] A hinge 102 rotatably connected between arc rings 101 is respectively provided with a servo 103. The servo 103 can drive the hinge 102 to rotate and open. When the hinge 102 opens, the distance between adjacent arc rings 101 can be increased. The servo 103 can drive the hinge 102 to close to reduce the distance between adjacent arc rings 101. When it is necessary to put the fixed hoop 1 on the lacquer tree, open the two snap-connected arc rings 101, and then start the servo 103 to rotate and open the hinge 102 to increase the distance between the joints of the remaining adjacent arc rings 101, so as to expand the distance of the opening of the fixed hoop 1. After the distance is increased, it is convenient for the lacquer tree to penetrate into the cavity.

[0026] After the lacquer tree penetrates into the fixed hoop 1, snap-connect the two arc rings 101, and at the same time start the servo 103 to rotate and close the hinge 102 to reduce the distance between the joints of the remaining adjacent arc rings 101, so that the four arc rings 101 surround to form a fixed hoop 1 with a certain rigid connection. At this time, the fixed hoop 1 is stably sleeved on the outer periphery of the lacquer tree.

[0027] The number of flight control mechanisms 5 is four. The four flight control mechanisms 5 are evenly spaced on the outer periphery of the fixed hoop 1. The four flight control mechanisms 5 can be started synchronously to raise or lower the fixed hoop 1 along the height direction of the lacquer tree. The structures of the four flight control mechanisms 5 are the same. Any one of the flight control mechanisms 5 includes an L-shaped support 503, an engine, a transmission system, a hub 502 and two blades 501 arranged on the support 503. The engine is connected to the blade 501 through the transmission system and the hub 502.

[0028] The output shaft of the engine is connected to the input shaft of the transmission system through a coupling. The output shaft of the transmission system is connected to the hub 502. The hub 502 is provided with a flapping hinge, a drag hinge and a pitch hinge. The root of the blade 501 is provided with a connecting lug that can be correspondingly connected to the aforementioned hinge. The connecting lug is connected to the hinge on the hub 502 through a pin shaft.

[0029] The lower side of the fixed hoop 1 is provided with an iris opening and closing fixing mechanism 2 for fixing the fixed hoop 1 on the lacquer tree. The iris opening and closing fixing mechanism 2 includes four chassis 201, four rotating arc plates 202 and four opening and closing triangular plates 203. The four chassis 201 are arranged corresponding to the four arc rings 101. Any one of the chassis 201 is fixedly connected to the corresponding arc ring 101 through a connecting column.

[0030] Four rotating arc plates 202 are arranged corresponding to four chassis 201, and the rotating arc plates 202 are slidably arranged on the lower side surfaces of the corresponding chassis 201. Installation grooves for installing the rotating arc plates 202 are formed on the lower side surfaces of the chassis 201, and the installation grooves are distributed along the length direction of the chassis 201. Sliding arc grooves are respectively formed on the inner side walls of the side edges on both sides of the installation grooves on the chassis 201, and the sliding arc grooves are distributed along the length direction of the chassis 201. The two long side edges of the corresponding rotating arc plate 202 along its length are respectively inserted into the corresponding sliding arc grooves, and the rotating arc plate 202 can rotate in the installation groove through the sliding fit between its side edges and the sliding arc grooves.

[0031] Straight teeth distributed along its length are formed on the inner side edge of any one of the rotating arc plates 202, and a notch is formed on the inner side wall of the chassis 201 corresponding to the inner side edge of the rotating arc plate 202. A driving motor (not shown in the figure), which is a servo motor, is fixed at the position of the notch. A driving gear is fixed on the output shaft of the driving motor, and the driving gear can be meshed and matched with the straight teeth on the rotating arc plate 202. The driving gear rotates under the drive of the driving motor, and the rotation of the driving gear can push the rotating arc plate 202 to rotate in the installation groove.

[0032] Four opening and closing triangular plates 203 are arranged corresponding to four chassis 201. One end of any one of the opening and closing triangular plates 203 is rotatably arranged on the chassis 201 located inside the corresponding rotating arc plate 202 through a rotating shaft. A rotating shaft is arranged on the outer side wall of the other end of the opening and closing triangular plate 203, and a connecting rod 204 is connected to the rotating shaft. The other end of the connecting rod 204 is rotatably arranged at the middle part of the corresponding rotating arc plate 202 through a rotating shaft.

[0033] The opening and closing triangular plate 203 is rotatably connected to the rotating arc plate 202 through the connecting rod 204. When the fixing hoop 1 moves to the height position of the set lacquer tree driven by the flight control mechanism 5, the four driving motors are started synchronously. The four rotating arc plates 202 rotate synchronously under the drive of the driving motors, and the synchronously rotating rotating arc plates 202 can push the corresponding opening and closing triangular plates 203 to move synchronously towards the middle of the cavity through the connecting rods 204 until they are clamped on the lacquer tree.

[0034] Correspondingly, when it is necessary to adjust the position of the fixing hoop 1 on the lacquer tree, the driving motors can be started synchronously. The output shafts of the driving motors rotate in the opposite direction, the corresponding rotating arc plates 202 rotate in the opposite direction, and the corresponding opening and closing triangular plates 203 are driven to move to open the cavity through the connecting rods 204, so as to facilitate the fixing hoop 1 to move up and down along the height direction of the lacquer tree driven by the flight control mechanism 5.

[0035] Furthermore, a pointed claw 205 is provided at the end of any one of the opening and closing triangular plates 203 away from the third end of the corresponding connecting rod 204 and the chassis 201, and the arc opening of the pointed claw 205 is arranged towards the cavity. When the opening and closing triangular plate 203 rotates and closes against the lacquer tree, the pointed claw 205 can be synchronously embedded in the lacquer tree, increasing the stability of the opening and closing triangular plate 203 against the lacquer tree.

[0036] The cutting and harvesting mechanism 3 is suspended below one side of the fixed hoop 1 for cutting incisions and collecting lacquer liquid. The cutting and harvesting mechanism 3 includes a machine body 302, a pushing component 304, a collecting spherical cavity 301, a plurality of fixed claw hands 303 and a cutting knife 305. The machine body 302 is suspended below one side of the fixed hoop 1 through a suspension lifting component 4, and the pushing component 304 is arranged on the outer side wall of the machine body 302. The pushing component 304 is used to push the machine body 302 towards the lacquer tree and fit it against the lacquer tree.

[0037] The pushing component 304 includes a cover cylinder 3041 fixed to the middle of the outer side wall of the machine body 302, a spiral blade 3042 arranged in the cover cylinder 3041, and a pushing motor (not shown in the figure) for driving the spiral blade 3042 to rotate. Both the upper and lower ends of the cover cylinder 3041 are open. One end opening of the cover cylinder 3041 is fixed to the machine body 302, and the other end opening of the cover cylinder 3041 faces outward. The pushing motor is arranged in the cover cylinder 3041, and the output shaft of the pushing motor faces outward. The middle of the spiral blade 3042 is fixed to the output shaft of the pushing motor. The spiral blade 3042 rotates under the drive of the pushing motor and pushes the machine body 302 towards the lacquer tree.

[0038] The number of the fixed claw hands 303 is four. The four fixed claw hands 303 are respectively rotatably arranged at the four corners of the machine body 302 through robotic arms, and the four fixed claw hands 303 are all arranged towards the cavity. The fixed claw hands 303 are connected to the robotic arms through arc-shaped connectors that can adapt to the curve of the outer peripheral surface of the lacquer tree, and the fixed grippers are connected to the arc-shaped connectors through universal shafts to enhance the grasping force of the fixed claw hands 303 and increase adaptability. The arrangement of the fixed claw hands 303 can stably fix the machine body 302 on the lacquer tree to ensure the stability of the subsequent cutting of the incision by the cutting knife 305.

[0039] The number of the cutting knives 305 is two. The two cutting knives 305 are symmetrically arranged on both side edges of the machine body 302 through robotic arms, and the two cutting knives 305 are all arranged towards the cavity. The cutting knives 305 are arranged at the ends of the corresponding robotic arms. The two cutting knives 305 can move under the drive of the corresponding robotic arms and cut out V-shaped or oblique incisions, and the lacquer liquid flows down from the incisions.

[0040] The collecting ball cavity 301 is rotatably arranged in the middle of the inner wall of the machine body 302. The collecting ball cavity 301 is used to be close to the incision and collect the paint liquid. The inside of the collecting ball cavity 301 is hollow and can collect and store a certain amount of paint liquid. The bottom of the collecting ball cavity 301 is rotatably arranged on the inner wall of the machine body 302 through a robotic arm hinge, and the collecting ball cavity 301 is moved to the position of the incision through the robotic arm hinge to collect the paint liquid.

[0041] A main conveying pipe 3011 for discharging the paint liquid is connected to the bottom of the collecting ball cavity 301. The main conveying pipe 3011 is connected to a transfer box. Two conveying pipes 3011 are connected to the end of the transfer box opposite to the main conveying pipe 3011. The other ends of the two conveying pipes 3011 are connected to a storage box 3012 for storing the paint liquid arranged on the upper end surface of the chassis 201. A vacuum pump 3013 is respectively connected to the two conveying pipes 3011. The negative pressure generated by the vacuum pump 3013 is used to suck the paint liquid into the collecting ball cavity 301 and convey it into the storage box 3012 through the conveying pipe 3011.

[0042] Furthermore, the suspension lifting assembly 4 is used to drive the cutting and harvesting mechanism 3 to move up or down vertically. The suspension lifting assembly 4 includes two lifting motors 401 fixedly arranged at intervals on the fixed hoop 1. A sleeve is respectively fixed on the output shafts of the two lifting motors 401. A pulling rope 402 is connected between the two sleeves and the machine body 302. One end of the pulling rope 402 is wound around the sleeve of one of the lifting motors 401. The middle of the pulling rope 402 is fixed on the outer wall of the machine body 302. The other end of the pulling rope 402 is wound around the sleeve of the other lifting motor 401. The two ends of the pulling rope 402 connected to the lifting motor 401 are kept parallel to ensure the stable up or down movement of the machine body 302.

[0043] When it is necessary to change the position of cutting and taking the paint, start the lifting motor 401. The pulling rope 402 is synchronously wound and released through the rotation of the sleeve to realize the up or down movement of the machine body 302. Only when the pulling rope 402 is lowered a certain distance, the cutting and harvesting mechanism 3 can be lowered to the corresponding position to cut the incision and take the paint. The position of the fixed hoop 1 does not need to be moved during the whole process. While being able to quickly change the cutting position, the energy consumption is also reduced.
