Description

Technical Field

[0001] This invention relates to an automatic pre-separation device and its application in tea cakes, belonging to the field of mechanical equipment technology. Background Technology

[0002] Automatic pre-separation equipment is a mechanical device that pre-cuts target products and is an indispensable component of modern production lines. Many products require the use of automatic pre-separation equipment in enterprise production.

[0003] For example, most Pu-erh tea on the market today is compressed tea, such as tea cakes or tea bricks, and there is very little loose Pu-erh tea. Making tea into tea cakes can preserve the aroma of the tea for a longer time, thereby slowing down the oxidation rate of polyphenols, ketones and chlorophyll. At the same time, it also reduces the volume of the tea leaves, making them easier to store. Although making tea into tea cakes has many advantages, it also causes some trouble for users when brewing tea, because tea cakes are very hard and therefore not easy to cut into small pieces.

[0004] Currently, when it is necessary to cut tea cakes, tea knives or small awls are usually used. However, in the process of cutting tea cakes, the tea cakes are easily broken apart, and a lot of residue is difficult to clean. In addition, it is easy to injure your hands, which makes it very inconvenient when brewing tea. Summary of the Invention

[0005] The present invention provides an automatic pre-separation device for making cuts on target products; and further, the automatic pre-separation is used for pre-cutting tea cakes.

[0006] The technical solution of this invention is:

[0007] According to one aspect of the present invention, an automatic pre-separation device is provided, comprising a cutting device 2, a lifting device 3, and a pressing device 4; the lifting device 3 is used to place a target product 85; under the pressing action of the pressing device 4, the cutting device 2 is used to make cuts on the target product 85.

[0008] The cutting device 2 includes a trajectory device 10, a sliding device 20, a feed power module 21, a blade 25, a cutting power module 26, and a contouring device 120. The feed power module 21 drives the blade 25, the cutting power module 26, and the contouring device 120 to move along a first direction following the sliding device 20. During the movement of the contouring device 120 along the first direction, the contouring device 120 is linked with the sliding device 20, enabling the blade 25 mounted on the contouring device 120 to move along a second direction. The contouring device 120 cooperates with the trajectory device 10, and the cutting power module 26 drives the blade 25 to cut a groove of the same shape as the trajectory plate in the trajectory device 10 on the target product 85.

[0009] The trajectory device 10 includes a trajectory plate I 16, a connecting plate IV 17, a trajectory plate II 18, and a connecting plate V 19; wherein, the connecting plate IV 17 and the connecting plate V 19 are respectively fixed to the frame 1, one end of the connecting plate IV 17 and the connecting plate V 19 is used to fix the trajectory plate I 16, and the other end of the connecting plate IV 17 and the connecting plate V 19 is used to fix the trajectory plate II 18. The trajectory plate I 16 and the trajectory plate II 18 are used to cooperate with the adjustment device 24 so that the trajectory bearing 63 in the adjustment device 24 is tightly attached to the trajectory plate I 16 and the trajectory plate II 18.

[0010] The contouring device 120 includes a tension spring 22, an adjusting device 24, a support plate I 33, and a support plate II 37. The support plates II 37 and I 33 are arranged vertically. The support plate I 33 is fixedly connected to the sliding device 20, and the adjusting device 24 is fixedly connected to the support plate II 37. The support plates I 33 and II 37 are connected by a guide shaft 31 in the sliding device 20, which drives the support plate II 37 to move along a second direction. The tension spring 22 provides a pulling force that brings the support plates I 33 and II 37 closer together, causing the trajectory bearing 63 in the adjusting device 24 to tightly adhere to the trajectory plates I 16 and II 18 in the trajectory device 10. When the trajectory bearing 63 moves along the trajectory of the trajectory plate, it drives the support plate II 37 to move along the second direction. The movement of the support plate II 37 causes the blade 25, fixed on the support plate II 37, to cut a groove of the same shape as the trajectory plate on the target product 85.

[0011] The adjustment device 24 includes a flexible shaft bracket 60, a universal flexible shaft 61, a trajectory bearing seat 62, a trajectory bearing 63, a support seat 64, an adjusting bolt 65, and a self-locking nut 66. The flexible shaft bracket 60 is fixed on the support plate I 33 in the contouring device 120. One end of the universal flexible shaft 61 is used for remote adjustment, and the other end of the universal flexible shaft 61 passes through the mounting hole of the flexible shaft bracket 60 and is connected to one end of the adjusting bolt 65. The other end of the adjusting bolt 65, which passes through the support seat 64, is locked by the self-locking nut 66 and installed on the trajectory bearing seat 62. By adjusting the adjusting bolt 65 at the remote end of the universal flexible shaft 61, the trajectory bearing seat 62 is brought closer to / away from the support plate II 37 in the contouring device 120, thereby achieving the adjustment of the cutting depth.

[0012] The lifting device 3 includes a connecting plate, a support rod, a compression spring, and a support 84; wherein, the two ends of the support rod fixed on the support 84 are respectively fixed to the frame 1 through the connecting plate, and a compression spring is sleeved on the support rod; the target product 85 placed in the support 84 is pressed by the compression spring and the pressing device 4.

[0013] The pressing device 4 includes a locking device 86, a pressing device 87, and a rotating power module 89. The pressing device 87 includes a cover plate 103, and the locking device 86, the pressing device 87, and the rotating power module 89 are fixed inside the cover plate 103. The rotating power module 89 cooperates with the pressing device 87 to drive the target product 85 placed in the lifting device 3 to rotate. The locking device 86 is used to lock / release the cover plate 103. By locking the cover plate 103, the target product 85 is pressed. By releasing the cover plate 103, the target product 85 to be separated is placed in and the target product 85 that has been separated is taken out.

[0014] The locking device 86 includes a lock head 90 and a rotating mechanism 91. The lock head fixing seat 93 in the lock head 90 and the connecting rod II 99 in the rotating mechanism 91 are fixedly connected to the cover plate 103. Rotating the rotating knob 102 in the rotating mechanism 91 drives the connecting rod in the rotating mechanism 91 to drag the push rod 97 in the lock head 90 to compress the compression spring III 96 in the lock head 90. At the same time, the lock tongue 92 in the lock head 90 retracts into the lock head fixing seat 93 to release the cover plate 103. Releasing the rotating knob 102 causes the compression spring III 96 to rebound. Under the thrust of the compression spring III 96, the connecting rod and the push rod 97 extend the lock tongue 92. The lock tongue pressing plate blocks the lock tongue 92 to complete the locking.

[0015] According to another aspect of the present invention, the automatic pre-separation described in any one of the above is used for pre-cutting tea cakes.

[0016] The cutter body 25 includes a cutter bar 45 and two sets of saw blades. The two sets of saw blades are symmetrically arranged on the cutter bar 45 through movable shoulders and clamping nuts. One end of the cutter bar 45 is fixed to the support plate II 37 of the contouring device 120 through a support side plate 35, and the other end of the cutter bar 45 is connected to the cutting power module 26. Each set of saw blades includes multiple saw blades, and the outer diameter of the multiple saw blades arranged from the center of the cutter bar 45 to the end increases sequentially.

[0017] The beneficial effects of this invention are as follows: This invention places the target product using a lifting device. Under the pressure of the clamping device, the blade in the cutting device can make cuts on the target product through the cutting groove of the lifting device. Throughout the process, the cutting device not only provides power in the cutting feed direction, but also, the contouring device and sliding device in the cutting device are linked, and the contouring device and trajectory device cooperate, enabling the cutting power module to drive the blade to cut a groove on the target product with the same shape as the trajectory plate in the trajectory device. Simultaneously, under the drive of the clamping device, rotation can be achieved, further cooperating with the cutting device and the lifting device to achieve longitudinal and transverse cuts on the target item in the feed direction. Through ingenious contouring and lifting structure design, this invention has high versatility for target products of different sizes, while also meeting the requirements of different cutting depths.

The feed power module 21 drives the blade 25, the cutting power module 26, and the contouring device 120 to move along a first direction following the sliding device 20. During the movement of the contouring device 120 along the first direction, the contouring device 120 is linked with the sliding device 20, enabling the blade 25 mounted on the contouring device 120 to move along a second direction. The contouring device 120 cooperates with the trajectory device 10, and the cutting power module 26 drives the blade 25 to cut a groove on the target product 85 with the same shape as the trajectory plate in the trajectory device 10.

[0061] Furthermore, the first direction is the feed direction, i.e., the axial direction of the cylindrical guide rail-support rail 27; the second direction is the up-down direction.

[0062] Furthermore, the trajectory device 10 includes a trajectory plate I 16, a connecting plate IV 17, a trajectory plate II 18, and a connecting plate V 19; wherein, the connecting plate IV 17 and the connecting plate V 19 are respectively fixed to the frame 1, one end of the connecting plate IV 17 and the connecting plate V 19 is used to fix the trajectory plate I 16, and the other end of the connecting plate IV 17 and the connecting plate V 19 is used to fix the trajectory plate II 18.

The trajectory device 10 works in conjunction with the contouring device 120 to complete the contouring and cutting of the tea cake and adjust the cutting depth according to the size of the tea cake.

[0064] Furthermore, the adjustment device 24 includes a flexible shaft bracket 60, a universal flexible shaft 61, a trajectory bearing seat 62, a trajectory bearing 63, a support seat 64, an adjusting bolt 65, and a self-locking nut 66.

At the same time, the lock tongue 92 in the lock head 90 retracts into the lock head fixing seat 93 to release the cover plate 103. Releasing the rotating knob 102 causes the compression spring III 96 to rebound. Under the thrust of the compression spring III 96, the connecting rod and the push rod 97 extend the lock tongue 92, and the lock tongue pressing plate blocks the lock tongue 92 to complete the locking.

[0068] According to another aspect of the present invention, automatic pre-separation is used for pre-cutting tea cakes.

[0069] Furthermore, the cutter body 25 includes a cutter bar 45 and two sets of saw blades.

The saw blade I 38 is also locked in place, with one side abutting against the already fixed clamping nut II 43 and the other side locked by clamping nut III 44. Furthermore, the threads on the blade shank and the clamping nut are reverse-threaded, ensuring the clamping nut tightens further as the saw blade rotates, thus preventing the blade from flying off. The left end of the blade shank 45 is fixed to the support plate II 37 via the support side plate 35 and bearing I 36. The other end is detachable, as detailed in the cutting power module 26.

[0077] like Figure 9 , 10As shown, the feed power module 21 includes a motor support I 46, a keyless synchronous pulley I 47, a feed motor 48, a synchronous belt I 49, a keyless synchronous pulley II 50, a lead screw support I 51, a lead screw 52, ​​a lead screw nut 53, a lead screw nut seat 54, a connecting seat 55, and a lead screw support II 56. The lead screw support I 51, lead screw 52, ​​lead screw nut 53, lead screw nut seat 54, and lead screw support II 56 form a standard lead screw motion module. The feed motor 48 is bolted to the motor support I 46, and then the motor support I 46 is connected to the connecting plate II 9 of the frame 1. The power of the feed motor 48 is transmitted to the lead screw motion module through the transmission chain composed of the keyless synchronous pulley I 47, the synchronous belt I 49, and the keyless synchronous pulley II 50. The lead screw motion module is connected to the support plate I 33 through the connecting seat 55, thereby converting the power into the feed power of the cutting device 2.

[0078] like Figure 11 , 12 As shown, the tea ash collection device 23 includes a brush bracket 57, a tea ash storage box 58, and an industrial brush 59. The brush bracket 57 serves as an intermediate connecting component, and the industrial brush 59 is bolted to the brush bracket 57. The brush bracket 57 is then bolted to the side of the support plate II 37. The tea ash storage box 58 is magnetically fixed to the side of the support plate II 37. The magnetic fixing is used to facilitate the disassembly of the tea ash storage box 58, making the cleaning of tea ash easier.

[0079] like Figure 16 , 17 As shown, the cutting power module 26 includes a cutting motor 68, a flange bearing 69, a motor support II 70, a keyless synchronous pulley III 71, a synchronous belt II 72, and a keyless synchronous pulley IV 73. The flange bearing 69 is bolted to the motor support II 70. The power of the cutting motor 68 is transmitted from the keyless synchronous pulley III 71 to the keyless synchronous pulley IV 73 via the synchronous belt II 72, which drives the cutter bar 45 to rotate. The motor support II 70 is bolted to the support plate II 37. The cutter body 25 is designed separately from the cutting power module 26 so that when a saw blade is damaged, the saw blade can be replaced from the side by simply disassembling the cutting power module 26.

[0080] like Figure 30 As shown, the contouring device 120 includes a tension spring 22, an adjusting device 24, a support plate I 33, and a support plate II 37; wherein the trajectory device 10 is fixedly connected to the aluminum alloy frame 5, the support plate I 33 is bolted to the cylindrical guide rail-slider 32, therefore the support plate I 33 is also fixed in the vertical direction, and the adjusting device 24 is bolted to the support plate II 37, and combined with... Figure 4 , Figure 5It can be seen that support plate I 33 and support plate II 37 are connected by a guide shaft 31 that can slide up and down in the flange linear bearing 28, so the adjusting device 24 can move in the up and down direction, such as... Figure 31 As shown, the two ends of the tension spring 22 are bolted through and fixed to the support plate I 33 and the support plate II 37 respectively. When the relative distance between the blade body 25 and the sliding device 20 increases, the tension spring will be in a stretched state, thereby generating movement to resist the increase in distance, eliminating the up-and-down jump of the blade body when cutting the object, and ensuring that the trajectory bearing 63 always fits against the trajectory plate I 16 and the trajectory plate II 18 during the movement. The support seat 64 in the adjusting device 24 is fixedly connected to the support plate II 37 of the blade body 25 by bolts, so the movement of the blade body 25 is also fixed. The movement is consistent with the adjustment device 24; the support plate II 37 is fixed to the guide shaft 31 in the sliding device 20 through the cooperation of M8×20 double-ended studs 34 and bolts. Because the guide shaft 31 can slide up and down relative to the sliding device 20, the support plate II 37 and the cutter body 25 fixed on the support plate II 37 can also slide up and down relative to the sliding device 20; when the track bearing 63 moves up and down along the track plate, it will drive the support plate II 37 to move up and down, thereby driving the cutter body 25 to cut a groove of the same shape as the track plate on the tea cake. This is the whole process of contouring.

[0081] like Figure 13 , 14As shown, the adjustment device 24 includes a flexible shaft bracket 60, a universal flexible shaft 61, a track bearing seat 62, a track bearing 63, a support seat 64, an M8×60 adjusting bolt 65, a self-locking nut 66, and an M5×10 countersunk bolt 67. The flexible shaft bracket 60 is fixed to the support plate I33 by bolt connection. The A end of the universal flexible shaft 61 passes through the hole at the bottom of the flexible shaft bracket 60. When the universal flexible shaft 61 moves up and down with the M8×60 adjusting bolt 65, the A end of the universal flexible shaft 61 always passes through the hole. The hole at the bottom of the flexible shaft bracket 60 prevents the universal flexible shaft 61 from swinging left and right, thus ensuring that end A of the universal flexible shaft 61 is in a preset position when remote adjustment is achieved. End B of the universal flexible shaft 61 is connected to the M8×60 adjusting bolt 65, the main function of which is to allow adjustment of the cutting depth by turning the M8×60 adjusting bolt 65 at end A. The track bearing 63 is fixed to the track bearing seat 62 by the thread at its end engaging with the threaded hole of the track bearing seat 62. Furthermore, the two ends of the track bearing seat 62... The edge is designed with a groove that matches the support base 64, limiting the trajectory bearing seat 62 to only move up and down, thus serving a guiding function. The support base 64 is fixed to the support plate II 37 by M5×10 countersunk bolts 67. The self-locking nut 66 and the M8×60 adjusting bolt 65 are threaded together, which locks the M8×60 adjusting bolt 65. The head of the M8×60 adjusting bolt 65 is tightly fitted to the support base 64 by a washer. When the M8×60 adjusting bolt 65 rotates, the head of the M8×60 adjusting bolt 65... The height of 5 will not change relative to the support seat 64, but the track bearing seat 62 and the M8×60 adjusting bolt 65 are connected by threads. When the M8×60 adjusting bolt 65 rotates, the track bearing seat 62 will inevitably move under the interaction of the threads. In addition, the groove guides the movement. Rotating the M8×60 adjusting bolt 65 can make the track bearing seat 62 approach / move away from the support plate II 37. When the track bearing seat 62 approaches the support plate II 37, the depth of the cutter cutting the tea cake becomes shallower, and when it moves away, it becomes deeper.

[0082] like Figure 18 , 19As shown, the lifting device 3 includes four sets of connecting devices symmetrically arranged based on the support 84. Each set of connecting devices includes two connecting plates, one support rod, and one compression spring. Taking two sets of connecting devices as an example, they include connecting plate IV 74, support rod I 75, self-lubricating bearing I 76, compression spring I 77, connecting plate V 78, connecting plate VI 79, support rod II 80, connecting plate VII 81, compression spring II 82, and self-lubricating bearing II 83. The self-lubricating bearings I 76 and II 83 are fixed to the support 84 by bolts. The support rods I 75 and II 80 concentrically pass through the self-lubricating bearings I 76 and II 83 and can slide up and down within them. The two ends of the support rods I 75 and II 80 are fixed to the connecting plates IV 74, V 78, VI 79, and VII 81 by nuts and locking washers. One end of the connecting plate IV74, connecting plate V78, connecting plate VI79, and connecting plate VII81 are fixed to the support beam I6 and the aluminum alloy frame 5 by T-nuts and bolts (as shown in the figure, the other ends of connecting plate IV74 and connecting plate VI79 are fixed to the aluminum alloy frame 5 by T-nuts and bolts, and the other ends of connecting plate V78 and connecting plate VII81 are fixed to the support beam I6 by T-nuts and bolts; the other four symmetrically designed connecting plates are fixed to the support beam II14 and the aluminum alloy frame 5. This connection method allows the support 84 to slide up and down under the action of force. The compression spring always has an upward pushing force on the support 84, while the pressing device 87 will press down the entire lifting device 3. Under the action of these two forces with opposite directions, the tea cake will always be tightly compressed, regardless of its size.

[0083] like Figure 20-29 As shown, the clamping device 4 includes a locking device 86, a pressing device 87, a supporting device 88, and a rotating power module 89.

The rotating power module 89, composed of a motor base side plate 117 and a motor base bottom plate 118, forms a motor support that is fixedly connected to the cover plate 103 in the pressing device 87 by bolts, thereby fixing the motor to the cover plate 103.

[0084] like Figure 21As shown, the locking device 86 includes a lock head 90 and a rotating mechanism 91. The lock head fixing seat 93 in the lock head 90 and the connecting rod II 99 in the rotating mechanism 91 are both fixed to the cover plate 103 in the pressing device 87 by bolts. At the same time, the push rod 97 in the lock head 90 and the connecting rod I 98 in the rotating mechanism 91 are connected by screws. The two together constitute the locking device 86.

[0085] like Figure 22 , 23 As shown, the lock head 90 in the locking device 86 includes a bolt 92, a lock head fixing seat 93, a push plate 94, a limiting plate 95, a compression spring III 96, and a push rod 97. One end of the bolt 92 is fixed to the limiting plate 95 by bolts. The outer diameter of the limiting plate 95 is larger than the hole diameter on the push plate 94, and its function is to prevent the bolt 92 from moving beyond its limit position. The push rod 97 passes through the square hole on the lock head fixing seat 93 and is fixed to the push plate 94 by bolts. The push rod 97 pushes the push plate 94 to move, thereby moving the bolt 92. The compression spring III 96 is attached to the end face of the limiting plate 95. It can provide a rebound force to the bolt 92 by the compressed compression spring III 96 when the lock head 90 is unlocked and the distance between the push plate 94 and the inner right end face of the lock head fixing seat 93 becomes smaller.

[0086] like Figure 24 , 25 As shown, the rotating mechanism 91 in the locking device 86 includes connecting rod I 98, connecting rod II 99, rotating seat 100, connecting rod III 101, and knob 102. The rotating seat 100 has three mounting shafts. Connecting rod I 98, connecting rod II 99, and connecting rod III 101 are respectively mounted on the rotating seat 100 via shafts. Connecting rod I 98 and connecting rod III 101 are fixed to the shafts on both sides of the bottom of the rotating seat 100 by self-locking washers and nuts. The hole in connecting rod II 99 is connected to the top shaft of the rotating seat 100 in a hole-shaft mounting manner. At the same time, connecting rod II 99 is fixed to the cover plate 103 by bolts. Rotating the knob 102 mounted on the top shaft end of the rotating seat 100 can drive connecting rod I 98 and connecting rod III 101 to move, thereby driving the locking tongue 92 to extend and retract.

[0087] like Figure 26 , 27As shown, the pressing device 87 includes a cover plate 103, a support rod III 104, a rubber plate 105, a pressure plate 106, a large gear 107, a turntable bearing outer ring 108, a turntable bearing inner ring 109, a nail 110, an auxiliary centering plate 111, a small gear 112, a support frame 113, and a hinge 114. The cover plate 103 serves as the carrier. The turntable bearing outer ring 108 is fixed to the cover plate 103 via the support rod III 104 using threads and nuts, serving only a supporting function. The turntable bearing inner ring 109 is fixed to the large gear 107 via bolts, serving only a rotational function. The pressure plate 106 is connected via… The rubber plate 105, nail 110, and auxiliary centering plate 111 are installed by bolt connection. The working surface of the auxiliary centering plate 111 and the tip of the nail 110 protrude from the bottom surface of the rubber plate 105. The nail 110, auxiliary centering plate 111, and rubber plate 105 are installed on the pressure plate 106 to ensure better rotation of the tea cake. The support frame 113 is fixed to the cover plate 103 by bolt connection. The cover plate 103 is fixed to the frame 1 by bolt connection through the hinge 114. When the rotational power is transmitted through the meshing of the small gear 112 and the large gear 107, the power is transmitted to the pressure plate 106 to rotate the tea cake by 90°.

[0088] like Figure 28 As shown, the support device 88 includes hydraulic support rod I 115 and hydraulic support rod II 116; wherein hydraulic support rod I 115 is connected to support frame 113 by double-ended studs, and hydraulic support rod II 116 is connected to aluminum alloy frame 5 by T-nuts and bolts; it plays a supporting role when the entire pressing device 4 is opened and the tea cake is placed in. The turntable bearing - outer ring 108, turntable bearing - inner ring 109, and balls constitute a standard turntable bearing;

[0089] like Figure 29 As shown, the rotary power module 89 includes a motor base side plate 117, a motor base bottom plate 118, and a rotary motor 119. The motor base side plate 117 and the motor base bottom plate 118 are connected by bolts to form a motor bracket, which allows the rotary power module 89 to be fixed to the cover plate 103 by bolt connection. The rotary motor 119 is fixed to the motor base bottom plate 118 by bolt connection, and the power of the rotary motor 119 is transmitted through the meshing of a pinion and a gear.

[0090] like Figure 32 , 33 As shown, the locking device 86 and the locking tongue pressing plate together complete the locking function. Figure 33 In the indicated state, rotating the rotary knob 102 moves the connecting rod, which in turn drags the push rod 97 towards the center. At this time, the compression spring Ⅲ 96 is compressed, and the locking tongue 92 retracts into the lock head fixing seat 93 (as shown). Figure 32As shown), the cover plate 103 can be opened smoothly at this time. Release the rotating knob 102, the compression spring Ⅲ 96 rebounds, and the connecting rod and push rod 97 extend the locking tongue 92 under the pushing force of the compression spring Ⅲ 96. At this time, the locking tongue pressing plate will block the locking tongue 92, and the locking device 86 and the locking tongue pressing plate complete the locking.

[0091] like Figure 34 , 35 As shown in Figure 36, Figure 35 The image shows workstation I. At this time, the track bearing 63 is located in the groove at one end of the track plate. The main purpose of setting this groove is to prevent the saw blade from contacting the tea cake when starting. At this time, the distance between support plate I 33 and support plate II 37 is assumed to be 80mm, and the tension spring 22 is deformed significantly. Figure 34 The diagram shows the intermediate state, where the distance between support plate I 33 and support plate II 37 is assumed to be 60mm, and the deformation of tension spring 22 is minimal. Figure 36 The diagram shows workstation II. At this time, the trajectory bearing 63 is located in the groove at the other end of the trajectory plate. The distance between support plate I 33 and support plate II 37 is assumed to be 80mm. The tension spring 22 has significant deformation. The entire workflow is as follows: Open cover plate 103, as... Figure 15 As shown, the tea cake to be cut is placed in the support 84. At this time, the state of the tea cake is as follows. Figure 37 As shown; cover plate 103 is closed, as... Figure 1 As shown, the cutting motor 68 is started to make the saw blade start to rotate, and then the feed motor 48 is started to drive the entire cutting device 2 to move from station I to station II at a constant speed. At this time, the state of the tea cake is as follows. Figure 38 As shown; both the feed motor 48 and the cutting motor 68 stop rotating, the rotary motor 119 starts, the tea cake is rotated 90° and then the rotary motor 119 stops, the cutting motor 68 starts again, and at the same time the feed motor 48 starts in reverse, driving the entire cutting device 2 to move from station II to station I at a constant speed laterally. At this time, the state of the tea cake is as follows. Figure 39 As shown; the cutting motor 68 stops, and the pre-separated tea cake is removed.

[0092] By applying the pre-separation device to tea cakes, it is evident that, compared to traditional hydraulic tea cake cutters, the motor-driven approach offers advantages such as smaller size, lighter weight, and a cleaner working environment. The contour-following cutting method ensures that the cut grooves match the curvature of the tea cake surface, resolving the issue of excessively deep cuts in thin sections and insufficiently shallow cuts in thick sections caused by horizontal saw blade cutting. This ensures that the tea cake shape is preserved while making it easier to break into smaller pieces. The adjustment device allows for adjustment of the cutting depth according to the size of the tea cake, enhancing the overall versatility of the mechanism. The lifting device, in conjunction with the pressing device, can adaptively fix tea cakes of different sizes, further improving the invention's versatility.
