Figure 2-Figure 3As shown, this embodiment provides a cutting mechanism, which includes a carrier body 221, a cutting component 222 and a separation component 223. The carrier body 221 can carry the workpiece 100 to be cut, and an escape space that can face the bundling piece 102 is provided on the carrier body 221; the cutting component 222 is configured to cut off the bundling piece 102 bundled on the workpiece body 101; the separation component 223 includes a first unwinding roller assembly 2231 and a second unwinding roller assembly 2232, the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 are both located below the cutting component 222 and face the escape space, and the two can rotate in opposite directions to roll the cut bundling piece 102 into the separation gap formed therebetween.

[0052] The cutting mechanism provided in this embodiment can cut off the bundle 102 tied on the workpiece body 101 carried on the supporting frame 221 by providing a cutting component 222; by providing a separating component 223, the cut bundle 102 can be rolled into the separation gap formed between the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232, so as to achieve the effect of separating the bundle 102 from the workpiece body 101; through the mutual cooperation between the cutting component 222 and the separating component 223, the bundle 102 tied outside the workpiece body 101 can be automatically cut, and the cut bundle 102 can be separated from the workpiece body 101, thereby reducing the workload of operators, reducing labor costs, improving feeding efficiency, and achieving good feeding consistency.

[0053] To ensure the safety of the cutting operation, an outer cover 225 is provided on the outer cover of the cutting component 222 and the separation component 223. Optionally, the outer cover 225 is provided with a feed port and a discharge port, and the cut piece 100 can be loaded from the feed port, and after the cutting operation is completed, the workpiece body 101 can be unloaded from the discharge port or transferred to the next process.

[0054] Furthermore, the support frame 221 includes a support panel, and a through hole is processed on the support panel to form the avoidance space, which has a simple structure and is easy to process. The two sides of the piece 100 to be cut are respectively carried on the support panels on both sides of the avoidance space. Optionally, the support frame 221 also includes a U-shaped frame, and the two U-shaped arms of the U-shaped frame are connected to the support panel and straddle the avoidance space of the support panel.

[0055] For the convenience of description, Figure 2 and Figure 3As shown, the length direction of the carrier body 221 is defined as the X direction, the width direction of the carrier body 221 is defined as the Y direction, and the height direction of the carrier body 221 is defined as the Z direction, wherein the X direction, the Y direction, and the Z direction only represent three directions perpendicular to each other in space and have no practical meaning. When the cut pieces 100 are loaded, the length direction of the binding piece 102 is parallel to the X direction, and the width direction of the binding piece 102 is parallel to the Y direction.

[0056] Figure 4 FIG. 2 shows a side view of a support frame 221 and a separation component 223 provided in an embodiment of the present invention. Figure 3-Figure 4 As shown, the separation component 223 also includes a separation support frame 2234 and a separation lifting drive assembly 2236. The separation support frame 2234 is arranged below the cutting component 222, and the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 are both rotatably arranged on the separation support frame 2234; the output end of the separation lifting drive assembly 2236 is connected to the separation support frame 2234 to drive the separation support frame 2234 to move in the vertical direction. After the workpiece 100 to be cut is transferred to the bottom of the cutting component 222, the separation lifting drive assembly 2236 can drive the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to move upward through the separation support frame 2234, so that the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 are in contact with the bottom surface of the binding member 102, thereby facilitating the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to separate the cut binding member 102 from the workpiece body 101; when the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 are in contact with the bottom surface of the binding member 102, ... thereby facilitating the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to separate the cut binding member 102 from the workpiece body 101; After the bundle 102 is rolled into the separation gap formed between the bundle 102 and the bundle 102, the separation lifting drive assembly 2236 can drive the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to move downward through the separation support frame 2234, thereby preventing the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 from continuing to rotate and rolling the workpiece body 101 into the separation gap, and also preventing the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 from directly contacting the bottom surface of the workpiece body 101, thereby causing surface damage to the workpiece body 101. In this embodiment, the separation lifting drive assembly 2236 is a lifting cylinder.

[0057] Specifically, the first unwinding roller assembly 2231 includes a first transmission rod and a first unwinding roller, the axis direction of the first transmission rod extends along the Y direction, and both ends of the first transmission rod are rotatably set on the separation support frame 2234, and the first unwinding roller is integrally formed on the first transmission rod; the second unwinding roller assembly 2232 includes a second transmission rod and a second unwinding roller, the axis direction of the second transmission rod extends along the Y direction, and both ends of the second transmission rod are rotatably set on the separation support frame 2234, and the second unwinding roller is integrally formed on the second transmission rod. This arrangement can facilitate the processing of the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232, save the time of assembling multiple parts, and improve the processing efficiency.

[0058] Further, the separation component 223 also includes a roll-out motor and a gear set 2235, and the roll-out motor drives the first roll-out roller assembly 2231 and the second roll-out roller assembly 2232 to rotate in opposite directions through the gear set 2235. Specifically, the gear set 2235 includes a driving gear 22351, a first driven gear 22352 and a second driven gear 22353, the first driven gear 22352 is coaxially connected to the first transmission rod, the second driven gear 22353 is coaxially connected to the second transmission rod, the driving gear 22351 is connected to the output end of the roll-out motor, and meshes with the first driven gear 22352, and the second driven gear 22353 meshes with the first driven gear 22352. When the unwinding motor is working, it can drive the driving gear 22351 to rotate, thereby driving the first driven gear 22352 and the second driven gear 22353 meshing with the first driven gear 22352 to rotate, thereby realizing the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to rotate in opposite directions.

[0059] Optionally, there are multiple first unwinding roller assemblies 2231, and the multiple first unwinding roller assemblies 2231 are arranged at intervals along the X direction; there are multiple second unwinding roller assemblies 2232, and the multiple second unwinding roller assemblies 2232 are arranged at intervals along the X direction. This arrangement can increase the contact area between the first unwinding roller assembly 2231 and the strapping piece 102 in the length direction, and the contact area between the second unwinding roller assembly 2232 and the strapping piece 102 in the length direction, improve the friction force and bearing capacity, and thus further ensure the unwinding effect and unwinding efficiency of the strapping piece 102.

[0060] In this embodiment, the number of the first unwinding roller assemblies 2231 is two, and the number of the second unwinding roller assemblies 2232 is two. Adaptively, the number of the first driven gears 22352 is two, corresponding to the two first transmission rods respectively, and the number of the second driven gears 22353 is two, corresponding to the two second driven gears 22353 respectively. The gear set 2235 also includes two reversing gears 22354, one of which is located between the two first driven gears 22352 and meshes with both the first driven gears 22352; the other reversing gear 22354 is located between the two second driven gears 22353 and meshes with both the second driven gears 22353, so as to realize the same direction rotation of the two first unwinding roller assemblies 2231, the same direction rotation of the two second unwinding roller assemblies 2232, and the opposite direction rotation of the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232.

[0061] Furthermore, if Figure 4 Combination Figure 2 As shown, the separation component 223 also includes a recycling box 2233, which is located below the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232. The recycling box 2233 is used to receive the unwound bundling 102 to achieve the recycling of the bundling 102, which can save the operator's time in cleaning the bundling 102 after the cutting operation is completed, reduce the operator's workload, and reduce labor costs.

[0062] Figure 5 The structure of the cutting component 222 provided in the embodiment of the present invention is shown in FIG. Figure 1 ; Figure 6 The structure of the cutting component 222 provided in the embodiment of the present invention is shown in FIG. Figure 2 .like Figure 5-Figure 6 As shown, the cutting component 222 includes a cutting bracket 2223, an adsorption component 2221 and a tool 2222. The cutting bracket 2223 can be raised and lowered on the carrier body 221 along the Z direction; the adsorption component 2221 is arranged on the cutting bracket 2223, and the adsorption component 2221 can adsorb the upper surface of the strapping piece 102 to form a cutting gap between the workpiece body 101 and the strapping piece 102; the tool 2222 is arranged on the cutting bracket 2223, and the tool 2222 can move along the width direction of the strapping piece 102 to cut the strapping piece 102 at a position corresponding to the cutting gap.

[0063] Optionally, the adsorption assembly 2221 includes multiple adsorption parts, which are divided into two groups and are located on both sides of the tool 2222. The multiple adsorption parts can all be suction cups connected to the vacuum generator. The multiple adsorption parts simultaneously adsorb the bundling piece 102 to ensure that the cutting gap formed between the workpiece body 101 and the bundling piece 102 is wide enough, thereby ensuring that the tool 2222 can smoothly extend into the cutting gap.

[0064] Furthermore, the cutting component 222 further includes a Z-direction driving member 2224, which is disposed on the carrier body 221, and the output end of the Z-direction driving member 2224 is connected to the cutting bracket 2223 to drive the cutting bracket 2223 to rise and fall along the Z direction. In this embodiment, the Z-direction driving member 2224 is a Z-direction lifting cylinder.

[0065] Furthermore, the cutting component 222 further includes a Y-direction driving member, which is disposed on the cutting bracket 2223, and the output end of the Y-direction driving member is connected to the cutter 2222 to drive the cutter 2222 to move along the Y direction, thereby realizing the cutting of the bundle 102. In this embodiment, the Y-direction driving member can be a linear motor or a cylinder, which has a simple structure and is easy to control.

[0066] Furthermore, the cutting component 222 also includes a pressing block 2225, which is arranged on the cutting bracket 2223 and can press the workpiece body 101 onto the carrier body 221. By setting the pressing block 2225, on the one hand, when the pressing block 2225 presses the workpiece body 101, the top surface of the workpiece body 101 can be made lower than the top surface of the binding member 102, and the cutting gap between the workpiece body 101 and the binding member 102 is made larger through the cooperation between the pressing block 2225 and the adsorption component 2221, further ensuring that the cutter 2222 smoothly extends into the cutting gap; on the other hand, it can also prevent the workpiece body 101 located at the lower layer from being simultaneously rolled into the separation gap formed between the first unwinding roller component 2231 and the second unwinding roller component 2232 when the separation component 223 separates the binding member 102 from the workpiece body 101.

[0067] Optionally, the number of the clamping blocks 2225 is four, and the four clamping blocks 2225 are arranged at intervals on the carrier body 221 and can be synchronously descended with the carrier body 221 to clamp the four corners of the workpiece body 101.

[0068] When there is no workpiece 100 to be cut below the cutting component 222, the cutting bracket 2223 drives the adsorption component 2221, the pressing block 2225 and the cutter 2222 to move upward in the Z direction to avoid it; when the workpiece 100 to be cut is located below the cutting component 222, the cutting bracket 2223 drives the adsorption component 2221, the pressing block 2225 and the cutter 2222 to move downward in the Z direction, so that the pressing block 2225 presses the four corners of the workpiece body 101, and the adsorption component 222 1 contacts the binding piece 102, and makes the adsorption component 2221 adsorb the upper surface of the binding piece 102, so that a cutting gap is formed between the binding piece 102 and the workpiece body 101; then, the Y-direction driving member drives the cutter 2222 to move along the Y direction, so that the binding piece 102 can be conveniently cut off. Through the arrangement of the adsorption component 2221 and the pressing block 2225, the cutting gap formed between the binding piece 102 and the workpiece body 101 can be wide enough to ensure that the cutter 2222 can smoothly extend into the cutting gap.

[0069] Figure 7 A schematic top view of a cutting mechanism provided in an embodiment of the present invention is shown. Figure 8 FIG. 2 shows a schematic diagram of the structure of the transmission component 224 provided in an embodiment of the present invention. Figure 7-Figure 8 As shown, the cutting mechanism also includes a transmission component 224, which is configured to receive the workpiece 100 to be cut in the previous process and transmit it to the bottom of the cutting component 222, and is configured to transfer the workpiece body 101 of the cutting bundle 102 to the next process, thereby realizing the full automation of the cutting mechanism. No manual labor is required throughout the process, reducing the workload of operators, reducing labor costs, and improving the transfer efficiency of the workpiece 100 to be cut.

[0070] Specifically, the transmission component 224 includes a transmission drive component 2241, a transmission load-bearing spline 2242 and a transmission lifting drive component 2243.

By setting up the transmission lifting driving assembly 2243, when the workpiece 100 to be cut is transferred, the transmission lifting driving assembly 2243 can drive the transmission bearing insert 2242 to move upward, which can avoid friction between the bottom surface of the workpiece 100 to be cut and the carrier body 221, thereby damaging the surface of the workpiece 100 to be cut, and can also avoid interference between the carrier body 221 and the transmission bearing insert 2242; when the workpiece 100 to be cut is transferred to the right place, the transmission lifting driving assembly 2243 can also drive the transmission bearing insert 2242 to move downward, so as to stably place the workpiece 100 to be cut on the carrier body 221. In this embodiment, the receiving mechanism of the next process is a transmission chain mechanism, and by setting up the transmission bearing insert 2242, the insert structure on the transmission bearing insert 2242 can be inserted into the gap of the transmission chain, so as to realize the stable transfer of the workpiece body 101.

[0071] To avoid interference between the transmission load-carrying insert 2242 and the separation component 223 , when the transmission load-carrying insert 2242 is transmitting the workpiece 100 to be cut, the separation lifting drive assembly 2236 can also drive the separation support frame 2234 to move downward to avoid the transmission load-carrying insert 2242 .

[0072] Optionally, an annular groove for avoiding the transmission load-carrying insert 2242 is provided on the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to avoid interference between the transmission load-carrying insert 2242 and the separation component 223 .

[0073] Optionally, the transmission drive assembly 2241 is a linear motor. The transmission component 224 also includes a guide rail, the transmission drive assembly 2241 and the guide rail are both arranged on the carrier body 221, and are located on both sides of the avoidance space of the carrier body 221, one end of the transmission load-bearing tooth 2242 is connected to the output end of the transmission drive assembly 2241 through a first connecting block, and the other end of the transmission load-bearing tooth 2242 is slidably matched with the guide rail through a second connecting block to achieve stable transmission of the transmission load-bearing tooth 2242 along the X direction.

[0074] To ensure that the cutting component 222 accurately cuts the bundle 102 , the transmission component 224 further includes a positioning assembly 2244 . The positioning assembly 2244 is disposed on the carrier body 221 . The positioning assembly 2244 is configured to position the to-be-cut piece 100 on the transmission carrier insert 2242 . Specifically, the positioning assembly 2244 includes an X-direction movable plate, a Y-direction movable plate, and a Y-direction fixed plate. The X-direction movable plate can be movably arranged in the avoidance space of the carrier body 221 along the Z direction. The X-direction movable plate can move upward to cooperate with the transmission load-carrying insert 2242 to realize the positioning of the to-be-cut 100 along the X direction.

The cutter 2222 cuts the bundle 102 at a position corresponding to the cutting gap.

[0082] (6) The unwinding motor works to drive the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 to rotate in opposite directions, so as to roll the cut bundle 102 into the separation gap formed therebetween, and the separation lifting drive assembly 2236 drives the separation support frame 2234 to move downward, so as to move the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 away from the workpiece body 101, and as the first unwinding roller assembly 2231 and the second unwinding roller assembly 2232 continue to rotate, the cut bundle 102 is rolled out into the recovery box 2233;

[0083] (7) The cutting bracket 2223 drives the adsorption assembly 2221, the pressing block 2225 and the cutter 2222 to move upward, and at the same time, the separation lifting drive assembly 2236 drives the separation support frame 2234 to move downward, so as to provide sufficient transfer space for the transmission bearing insert 2242 to transmit the workpiece 100 to be cut;

[0084] (8) The transmission driving assembly 2241 drives the transmission bearing insert 2242 to move along the X direction to the bottom of the cutting component 222, and the transmission lifting driving assembly 2243 drives the transmission bearing insert 2242 to move upward to support the workpiece body 101;

[0085] (9) The transmission driving assembly 2241 drives the transmission carrying insert 2242 to move along the X direction, so as to transfer the workpiece body 101 on the transmission carrying insert 2242 to the next process.
