Description

Technical Field

[0001] This invention relates to a pre-separation device for target items, belonging to the field of mechanical equipment. Background Technology

[0002] Pre-separation devices are mechanical equipment used to cut grooves into target products and are an indispensable component of modern production lines. For example, most Pu-erh tea on the market today is compressed tea, such as tea cakes or tea bricks, with very little loose Pu-erh tea available. Making tea cakes allows the aroma of the tea to be preserved for a longer time, thus slowing down the oxidation rate of polyphenols, ketones, and chlorophyll. It also reduces the volume of the tea leaves, making them easier to store. While making tea cakes has many advantages, it also creates some inconvenience for users when brewing tea because tea cakes are very hard and therefore not easy to cut into small pieces. Currently, when it is necessary to cut tea cakes, tea knives or small awls are usually used. However, during the process of cutting tea cakes, it is easy to break the tea cake apart, and the cut tea pieces are of different sizes. At the same time, a lot of residue is difficult to clean, and it is easy to injure hands, making it very inconvenient when brewing tea. Summary of the Invention

The power of the first power unit 16 is transmitted to the lead screw motion module through keyless synchronous pulley I14, keyless synchronous pulley II17, and synchronous belt I18. When the power is transmitted to the lead screw motion module, the rotation of the lead screw I23 causes the lead screw nut I20 to slide in translation on the lead screw I23. Since the lead screw nut seat I21 and the lead screw nut I20 are fixedly connected by bolts, and the connecting plate IV22 is also fixedly connected to the lead screw nut seat I21 by bolts, the lead screw nut I20, the lead screw nut seat I21, and the connecting plate IV22 move synchronously. Meanwhile, connecting plate II10 is fixed to the bottom of aluminum alloy drawer 11 by bolts and T-nuts. Connecting plate IV22 is then fixed to connecting plate II10 by bolts, causing the screw nut I20, screw nut seat I21, connecting plate IV22, and connecting plate II10 to move synchronously, thereby transmitting the power of the first power unit 16 to the movement of aluminum alloy drawer 11. Connecting plate II10 is fixed to the top of aluminum alloy frame 5 by bolts and T-nuts to fix the feed power module 4.

[0063] like Figure 5 As shown, the clamping device 2 includes a clamping base 25 and a clamping link structure 26; four clamping link structures 26 are arranged in a circumferential array at equal angles on the clamping base 25, and the link support seat 50 in the clamping link structure 26 is fixedly connected to the base connecting plate 28 in the clamping base 25 by bolt connection; one end of the pull rod 52 in the clamping link structure 26 is connected to the hole of the pull rod 52 concentrically with the hole of the rotating nut 37 in the clamping base 25 by an M5×10 pin 57.

[0064] like Figure 6 , Figure 7The clamping base 25 shown includes a turntable bearing outer ring 27, a base connecting plate 28, a support rod I 29, a turntable bearing inner ring 58, a second power unit 30, a synchronous pulley I 31, a synchronous belt II 32, a synchronous pulley II 33, a flange bearing I 34, a base bottom plate 35, a synchronous pulley III 36, a rotating nut 37, an auxiliary centering plate 38, a synchronous belt III 39, a motor support base plate 40, a motor support side plate 41, a synchronous pulley IV 42, a third power unit 43, a support rod II 44, a base top plate 45, a lead screw II 46, and a miniature bearing I 47; wherein the base bottom plate 35 serves as the base plate of the clamping base 25, and the support rod I 29 serves as the base plate of the base bottom plate 35 and the turntable bearing outer ring 58. The connecting part of ring 27 has threads at both ends. One end is threaded to the threaded hole on the base plate 35, and the other end passes through the through hole on the outer ring 27 of the slewing bearing. With the help of a self-locking washer and a nut, the base plate 35 and the outer ring 27 of the slewing bearing are fixed together, while also ensuring that there is space between them to install other components. The base connecting plate 28 is fixed to the inner ring 58 of the slewing bearing by bolts. At the same time, the inner ring 58 of the slewing bearing and the outer ring 27 of the slewing bearing form a slewing bearing, which is a common standard part in industry. This allows the base connecting plate 28 and all the components installed on it to rotate relative to the fixed part clamping the base 25. The power for this rotation comes from the second power unit 30, which is bolted to the base connecting plate 28. Synchronous pulley I 31 is fixed to the power shaft of the second power unit 30 by set screws, and synchronous pulley II 33 is bolted to the base connecting plate 28. The two are then connected by a synchronous belt II 32 to form transmission chain I. Through this transmission chain I, the power from the second power unit 30 drives the rotation of the base connecting plate 28 and all components mounted on it. Since both the second power unit 30 and synchronous pulley II 33 are fixed to the base connecting plate 28, the distance between synchronous pulley I 31 and synchronous pulley II 33 relative to their axes remains constant, ensuring the effectiveness of transmission chain I. Support rod II 44 uses the same connection method as support rod I 29 to fix the base connecting plate 28 to the base top plate 45, while also ensuring the movement space between them. Rotary nut 37 engages with lead screw II 46 through a central threaded hole. One end of the lead screw II 46 is bolted to the vertical direction of the base plate 35 via the flange bearing I 34, while the other end is connected to the base top plate 45 via the miniature bearing I 47. An open retaining ring is used to prevent the miniature bearing I 47 from moving up and down. In this way, the lead screw II 46 is installed on the axis of the entire clamping device 2, which can rotate around the axis while preventing it from moving up and down.The rotation of lead screw II 46 comes from the third power unit 43. The motor support-base plate 40 and the motor support-side plate 41 are connected by bolts to form a motor bracket, which fixes the third power unit 43 to the base connecting plate 28. The synchronous pulley IV 42 is fixed to the power shaft of the third power unit 43 by set screws. The synchronous pulley III 36 is fixed to the lead screw II 46 coaxially by set screws. The two are then connected by the synchronous belt III 39 to form transmission chain II. Through this transmission chain II, the power of the third power unit 43 can drive the lead screw II 46 to rotate. When the lead screw II 46 rotates, the rotating nut 37 will move up and down along the axis of the lead screw II 46 under the action of the thread (transmission chain I and transmission chain II are arranged vertically). The auxiliary centering plate 38 is concentrically fixed to the base top plate 45 by bolts. Its main function is to prompt the operator to place the object to be cut with the central groove on the base top plate 45. This can improve the efficiency and effect of centering and clamping. For objects to be cut without the central groove, the auxiliary centering plate 38 can be removed without affecting the centering and clamping function.

[0065] like Figure 8 , Figure 9As shown, the clamping linkage structure 26 includes a first slide rail 48, a first slider 49, a linkage support 50, a steering rod 51, a pull rod 52, a connecting plate V 53, a clamping pin 54, an M5×20 double-headed pin 55, a miniature bearing II 56, and an M5×10 pin 57. The linkage support 50 is bolted to the base connecting plate 28 in the clamping base 25. The first slide rail 48 and the first slider 49 form a standard linear slide rail. The first slide rail 48 is bolted to the linkage support 50, and the connecting plate V 53 is bolted to... The first slider 49 is fixed, ensuring that the connecting plate V53 can only slide horizontally regardless of the direction of the force applied. One end of the M5×20 double-ended pin 55 is fixed to the connecting plate V53 via a self-locking washer and nut, while the other end passes through the groove of the steering rod 51. The middle hole of the steering rod 51 is connected to the protruding pin of the connecting rod support seat 50 via a miniature bearing II 56, and the bearing is locked by an open retaining ring to prevent it from moving. This allows the steering rod 51 to rotate on the connecting rod support seat 50. The bottom end of the steering rod 51 is connected to the tie rod 52 via an M5×10 pin 57. The hole at one end is concentrically connected to the hole at the bottom end of the steering rod 51, and then the M5×10 pin 57 is locked with an open retaining ring. In this way, the connecting rod support 50, the tie rod 52, and the connecting plate V 53 are connected in series with the steering rod 51 as the intermediate connecting member to form a kinematic chain that can drive the connecting plate V 53 to slide left and right. The other end of the tie rod 52 is also connected to the hole of the rotating nut 37 concentrically through the M5×10 pin 57. In summary, the third power unit 43 serves as the power source and is composed of synchronous pulley III 36, synchronous belt III 39, and synchronous pulley IV 42. The transmission chain II transmits power to the lead screw II 46. The rotation of the lead screw II 46 causes the rotating nut 37 to slide up and down along the axis. When the rotating nut 37 slides down, it pushes the pull rod 52 outward. The pull rod 52 generates an outward thrust on the steering rod 51. When the end of the steering rod 51 connected to the pull rod 52 moves outward, the other end connected to the connecting plate V 53 will move in the opposite direction, i.e., slide inward along the slide rail, thus clamping the object to be cut. When the rotating nut 37 slides up, it pushes the pull rod 52 inward, thus releasing the object to be cut. When the second power device 30 acts as a power source, it transmits power to the base connecting plate 28 through the transmission chain I composed of synchronous pulley I 31, synchronous belt II 32, and synchronous pulley II 33. This causes the base connecting plate 28 and all the components mounted on it to rotate, which also achieves the function of changing the cutting direction of the object to be cut. The clamping nail 54 is fixed to the side of the connecting plate V 53 by threads, which makes it easier to change the cutting direction of the object to be cut.

[0066] like Figure 10As shown, the cutting device 3 includes a sliding device 59, a thrust spring 60, a contour adjustment device 61, a blade body 62, a cutting power module 63, and a synchronous belt IV 64. The two second slide rails 65 in the sliding device 59 are fixed to the top aluminum alloy crossbeam of the frame 1 by T-bolts and self-locking nuts, thus suspending the entire cutting device 3 at the top of the frame 1. The movable cooperation between the internal components of the sliding device 59 makes it the actuator of movement within the cutting device 3. The thrust spring 60 is concentrically installed with the guide shaft 69 in the sliding device 59. In its natural state, the spring's length is such that one end abuts against the support plate II 91 in the blade body 62, and the other end abuts against the flange linear bearing 68 in the sliding device 59. When the relative distance between the blade body 62 and the sliding device 59 decreases, the spring is compressed, generating movement to resist this decrease in distance and eliminating the up-and-down jumping of the blade body when cutting the object. The connecting seat 73 and the self-lubricating bearing 75 in the contour adjustment device 61 are both bolted to the support plate II 91 in the cutter body 62, so it can control the cutting trajectory of the cutter body during the cutting process and adjust the cutting depth. One end of the M8×20 double-ended stud 70 is threaded to the guide shaft 69, and the other end of the M8×20 double-ended stud 70 passes through the support plate II 91 of the cutter body 62 and is fixed by a washer and nut. Because the guide shaft 69 can slide up and down relative to the sliding device 59, the cutter body 62 can also slide up and down relative to the sliding device 59. The cutting power module 63 is bolted to the support plate II 91 in the cutter body 62, and transmits power to the cutter bar 87 in the cutter body 62 through the transmission chain III composed of the synchronous belt IV 64, the keyless synchronous pulley III 94, and the keyless synchronous pulley IV 97, thereby driving the rotation of the saw blade.

[0067] like Figure 11 , 12As shown, the sliding device 59 includes a second slide rail 65, a washer 66, an M8×16 socket head cap screw 67, a flange linear bearing 68, a guide shaft 69, an M8×20 double-ended stud 70, a second slider 71, and a support plate I 72. The second slide rail 65 and the second slider 71 form a standard cylindrical guide rail. The support plate I 72 is bolted to the second slider 71. Simultaneously, the support plate I 72 is bolted to the connecting plate VI 107 in the feed power module 4. Thus, the power from the fourth power device 100 can be transmitted to the support plate I 72, driving the second slider 71, thereby enabling the entire cutting device 3 to move left and right along the trajectory of the second slide rail 65. The flange linear bearing 68 is bolted to the second slider 71. Connected to support plate I 72, guide shaft 69 is concentrically placed within it. Guide shaft 69 can slide up and down inside flange linear bearing 68. The upper end of guide shaft 69 is connected to M8×16 socket head cap bolt 67 via thread. The function of this bolt is to fix washer 66 to the upper end of guide shaft 69. The outer diameter of washer 66 is larger than the hole diameter of flange linear bearing 68, which can prevent guide shaft 69 from dislodging from flange linear bearing 68 when moving up and down. The lower end of guide shaft 69 is connected to M8×20 double-ended stud 70 via thread. M8×20 double-ended stud 70, together with self-locking washer and nut, is fixed to support plate II 91, forming a linkage between sliding device 59 and cutter body 62, so that cutter body can move up and down, thereby making the cut groove the same as the surface shape of the object to be cut.

[0068] like Figure 13 , 14 As shown, the contouring adjustment device 61 includes a connecting seat 73, an adjusting plate 74, a self-lubricating bearing 75, a support rod Ⅲ 76, a U-shaped plate 77, a contouring wheel 78, an M10×35 bolt 79, and a self-locking nut 80. The connecting seat 73 and the self-lubricating bearing 75 are both bolted to the support plate Ⅱ 91 in the cutter body 62. The M10×35 bolt 79 passes through the top through hole of the connecting seat 73 and is locked onto the connecting seat 73 by the self-locking nut 80. Its bottom is threaded into the threaded hole of the adjusting plate 74. The support rod Ⅲ 76 is concentrically placed in the self-lubricating bearing 75 and can slide up and down. One end of the support rod Ⅲ 76 passes through the through hole of the adjusting plate 74, and a self-locking washer and nut, along with the shoulder of the support rod Ⅲ 76, secure the adjusting plate 74 to one end of the support rod Ⅲ 76. The other end of the support rod Ⅲ 76 is threaded into the threaded hole of the U-shaped plate 77, securing the two together. The contour wheel 78 is fixed to the bottom of the U-shaped plate 77 by a pin. With this connection, when the M10×35 bolt 79 is rotated, the height of the adjusting plate 74 can be changed by the action of the thread and the threaded hole, which drives the support rod Ⅲ 76 to move in the self-lubricating bearing 75, thereby achieving the function of adjusting the height of the contour wheel 78.

[0069] like Figure 15 , 16As shown, the blade body 62 includes a supporting left side plate 81, bearing III 82, saw blade I 83, saw blade II 84, saw blade III 85, movable shoulder 86, blade shank 87, clamping nut I 88, clamping nut II 89, clamping nut III 90, support plate II 91, supporting right side plate 92, flange bearing II 93, and keyless synchronous pulley III 94; wherein the movable shoulder, clamping nut, and saw blade are symmetrically installed, the movable shoulder 86 is fixed to the blade shank 87 by a set screw, and one side of the saw blade III 85 abuts against the fixed movable shoulder 86 on the other side. The saw blade 84 is locked by the clamping nut I88 on one side and by the clamping nut II89 on the other side. The saw blade 83 is locked by the clamping nut III90 on one side and by the clamping nut II89 on the other side. The left end of the cutter bar 87 is connected to the left support plate 81 via bearing III82 and the bearing III82 is locked by an open retaining ring to prevent the cutter bar 87 from moving left and right. The right end of the cutter bar 87 is connected to the right support plate 92 via flange bearing II93. The keyless synchronous pulley III94 is concentrically installed at the end of the cutter bar 87. The left support plate 81 and the right support plate 92 are fixed to the support plate II91 by bolts, thus forming the complete cutter body 62. The power for rotating the cutter bar comes from a DC motor 95 and is transmitted through a transmission chain Ⅲ consisting of a keyless synchronous pulley Ⅲ 94, a synchronous belt Ⅳ 64, and a keyless synchronous pulley Ⅳ 97. Furthermore, the threads on the cutter bar and the clamping nut are in reverse thread engagement. As the saw blade rotates, the clamping nut will tighten more and more, thus preventing the dangerous situation of the cutter flying off.

[0070] like Figure 17 As shown, the cutting power module 63 includes a DC motor 95, a motor bracket II 96, and a keyless synchronous pulley IV 97. The DC motor 95 is fixedly connected to the motor bracket II 96 by bolts, and the motor bracket II 96 is fixedly connected to the support plate II 91 by bolts. The keyless synchronous pulley IV 97 is concentrically mounted on the power shaft of the DC motor 95 and forms a transmission chain III with the keyless synchronous pulley III 94 and the synchronous belt IV 64 to transmit the power of the DC motor 95.

[0071] In summary, the contour cutting process of the cutting device 3 is as follows: When the blade 62 hangs down naturally under gravity, the thrust spring 60 is in its natural state, and the washer 66 is tightly attached to the surface of the flange linear bearing 68, preventing the guide shaft 69 from sliding further downward, thus suspending the entire blade 62. The fourth power device 100 is activated, and the feed power module 4 drives the entire cutting device 3 to feed at a uniform speed. At the same time, the cutting power module 63 drives the blade bar 87 to rotate, and the saw blade begins to rotate. When the saw blade begins to contact the object to be cut, the blade 62 will overcome gravity and be lifted to a certain height, thereby compressing the thrust spring 60. After being compressed, the spring will generate a downward thrust on the blade. Combined with the weight of the blade 62 itself, the combined force of the thrust and gravity will create a large pressure on the blade 62, making the saw blade tightly adhere to the blade. The saw blade cuts along the surface of the object. As the cutting process progresses, the saw blade creates a groove in the object. The blade 62 slowly descends as this groove appears, but it does not fall to its natural state. When it reaches the preset cutting depth, the contour wheel 78 contacts the object's surface. The thrust of the push spring 60 decreases but does not disappear. Combined with the weight of the blade 62 itself, this ensures that the contour wheel remains in close contact with the surface of the object throughout the entire feed motion. Ultimately, the shape of the groove will be the same as the shape of the object's surface. This is a contour cutting process. The cutting depth is the distance between the bottom cut surface of the contour wheel 78 and the bottom cut surface of the smallest saw blade in the blade 62. Therefore, by adjusting the height of the contour wheel (equivalent to the saw blade), the cutting depth can be adjusted according to the actual situation.

[0072] like Figure 18 , 19As shown, the feed power module 4 includes a keyless synchronous pulley V98, a motor support III99, a fourth power device 100, a keyless synchronous pulley VI101, a synchronous belt V102, a lead screw support III103, a lead screw III104, a lead screw nut II105, a lead screw nut seat II106, a connecting plate VI107, and a lead screw support IV108. The lead screw support seat Ⅲ103, lead screw nut Ⅱ105, lead screw nut seat Ⅱ106, lead screw Ⅲ104, and lead screw support seat Ⅳ108 constitute a standard lead screw motion module. The lead screw support seat Ⅲ103 and lead screw support seat Ⅳ108 are fixed to the connecting plate Ⅲ12 by bolts, so that the entire lead screw motion module is fixed to the top of the frame 1. The fourth power unit 100 is fixed to the motor support Ⅲ99 by bolts, and then fixed to the connecting plate Ⅲ12 of the frame 1 through the motor support Ⅲ99, so that the fourth power unit 100 is fixed to the top of the frame 1. Keyless synchronous pulley V98 is concentrically mounted on the transmission shaft of the fourth power unit 100, and keyless synchronous pulley VI101 is concentrically mounted on one end of the lead screw Ⅲ104. The power of the fourth power unit 100 is transmitted to the lead screw motion module through keyless synchronous pulley V98, keyless synchronous pulley VI101, and synchronous belt V102. When the power is transmitted to the lead screw motion module, the rotation of the lead screw Ⅲ104 causes the lead screw nut Ⅱ105 to slide in the lead screw Ⅲ104. Since the lead screw nut seat Ⅱ106 is fixedly connected to the lead screw nut Ⅱ105 by bolts, and the connecting plate VI107 is also fixedly connected to the lead screw nut seat Ⅱ106 by bolts, the lead screw nut Ⅱ105, the lead screw nut seat Ⅱ106, and the connecting plate VI107 move synchronously. At the same time, the connecting plate VI107 is fixed to the support plate I72 by bolt connection, which causes the screw nut II105, screw nut seat II106, connecting plate VI107 and support plate I72 to move synchronously, thereby transmitting the power of the fourth power device 100 to the sliding device 59 to drive the feed movement of the cutting device 3.

[0073] like Figure 20 , 21 As shown in Figures 22, 23, and 24, the entire cutting process of the pre-separator with self-centering clamping and contouring functions is as follows: Figure 20In state I, the first power unit 16 drives the aluminum alloy drawer 11 to the position shown in the diagram. This position is defined as position I, and the position of the cutting device 3 at this time is defined as position II. The worker places the object to be cut on the base top plate 45 in the clamping device 2. At this time, the third power unit 43 is activated. The third power unit 43 acts as a power source and transmits power to the lead screw 2 46 through the transmission chain 2 composed of synchronous pulley 36, synchronous belt 39, and synchronous pulley 42. The rotation of the lead screw 2 46 drives the rotating nut 37 to slide downward along the axis. When the rotating nut 37 slides downward, it pushes the pull rod 52 to move outward. The pull rod 52 generates an outward thrust on the steering rod 51. When the end of the steering rod 51 connected to the pull rod 52 moves outward, the other end connected to the connecting plate 53 will move in the opposite direction, that is, slide inward along the slide rail to clamp the object to be cut. The first power unit 16 is activated again to drive the aluminum alloy drawer 11 to move. Figure 21 The position shown is defined as position III. Simultaneously, the fourth power unit 100 starts when the aluminum alloy drawer 11 reaches this position, and the feed power module 4 drives the entire cutting device 3 to feed at a constant speed. At the same time, the cutting power module 63 drives the blade arm 87 to rotate, and the saw blade begins to rotate. When the saw blade begins to contact the object to be cut, the blade body 62 overcomes gravity and is lifted to a certain height, thus compressing the thrust spring 60. The compressed spring exerts a downward thrust on the blade body, which, combined with the weight of the blade body 62, creates a significant pressure on the blade body 62, causing the saw blade to... The saw blade cuts closely against the surface of the object. As the cutting process continues, the saw blade creates a groove in the object. The blade 62 slowly descends as this groove appears, but it doesn't fall to its natural state. Because after falling a certain distance, the contour wheel 78 contacts the object's surface. The thrust of the thrust spring 60 decreases but doesn't disappear, and combined with the weight of the blade 62 itself, the contour wheel remains in close contact with the object's surface throughout the entire feed motion. Ultimately, the shape of the groove will match the shape of the object's surface. This is one stage of the contour cutting process. Figure 21 State II is shown, and the position of the cutting device 3 at this time is defined as position IV. The state of the object being cut and the clamping device 2 at this time is as follows. Figure 22 As shown; the second power unit 30 starts, driving the base connecting plate 28 and all components mounted on it to rotate 90°, then the second power unit 30 stops, and the fourth power unit 100 starts in the reverse direction, repeating the contour cutting process in reverse, until... Figure 23In state III, the cutting device 3 returns from position IV to position II, and the fourth power device 100 and DC motor 95 stop. Then, the first power device 16 restarts, driving the aluminum alloy drawer 11 from position III to position I. Simultaneously, the third power device 43 starts, acting as a power source. Through the transmission chain II composed of synchronous pulley III 36, synchronous belt III 39, and synchronous pulley IV 42, the third power device 43 transmits power to the lead screw II 46. The rotation of the lead screw II 46 causes the rotating nut 37 to slide upwards along the axis. When the rotating nut 37 slides upwards, it pushes the pull rod 52 inwards. The pull rod 52 generates an inward pulling force on the steering rod 51. When the end of the steering rod 51 connected to the pull rod 52 moves inwards, the other end connected to the connecting plate V 53 will move in the opposite direction, i.e., slide outwards along the slide rail, thus releasing the object to be cut, forming a... Figure 24 State IV, as shown, involves cutting six equally spaced grooves in both the horizontal and vertical directions on the surface of the tea cake to pre-separate it.
