[0002] The hot-drilling pattern roll is pasted with hot-drilling. The hot-drilling pattern roll is cut into sheets according to production requirements by cutting each segment pasted on the roll adhesive. Because the drills pasted on the adhesive tape have certain uncertainty factors, that is, there are length differences and the possibility of scattered drills. Therefore, it is necessary to cut a picture from the gap of a line without drills, and ensure that the diamonds will not be cut. The positioning of the cutting is very difficult. If the positioning is wrong, the cutter will fall on the diamonds, causing damage to the cutter. Therefore, it cannot be cut at a fixed length. In order to avoid the low efficiency of the traditional manual cutting method, an automatic cutting positioning technology is urgently needed. Summary of the invention

[0008] Preferably, the further transmission assembly includes a power roller and a pressure roller arranged up and down.

[0009] Preferably, the pressure roller is a silicone pressure roller.

[0010] Preferably, the first sensor and the second sensor are photoelectric sensor switches or travel switches.

[0032] The present embodiment discloses a slitting and positioning device for automatically slitting hot drilling patterns, comprising a conveyor belt, a machine platform 7, a photoelectric sampling axis 5, a first sensor 3, a second sensor 4, a transmission component, a cutter 10 and a single-chip microcomputer, wherein the first sensor 3 and the second sensor 4 are both communicatively connected to the single-chip microcomputer.

[0033] The conveyor belt is located on one side of the machine platform 7. The conveyor belt is used to convey the hot-drilling pattern coil 2. The hot-drilling pattern coil 2 is provided with hot-drilling 1. The conveyor belt is a device for conveying the hot-drilling pattern coil 2 that has not been delivered to the machine platform 7. Through the cooperation of the conveyor belt, the hot-drilling pattern coil 2 entering the machine platform 7 can be made flat, ensuring the accuracy of subsequent cutting. The machine platform 7 is an installation platform. The photoelectric sampling shaft 5, the first sensor 3, the second sensor 4, the continuous transmission component, and the cutter 10 can all be directly or indirectly installed on the machine platform 7. After the hot-drilling pattern coil 2 is conveyed by the conveyor belt and delivered to the machine platform 7, it continues to be conveyed under the drive of the continuous transmission component, and is then conveyed to the bottom of the cutter 10 for slitting.

[0034] The photoelectric sampling shaft 5 is arranged between the continuous transmission component and the conveyor belt. The photoelectric sampling shaft 5 is a rotatable optical shaft, and the bottom surface of the photoelectric sampling shaft 5 is in contact with the top surface of the hot-drilling pattern coil 2. It should be noted that the in contact here means pressing on the surface of the hot-drilling pattern coil 2, so as to achieve the purpose of accurately contacting the hot-drilling 1 thereon without over-pressing. The first sensor 3 and the second sensor 4 are installed at both ends of the photoelectric sampling shaft 5. It is feasible that a photoelectric sampler bracket 6 is installed at both ends of the photoelectric sampling shaft 5, and the photoelectric sampler bracket 6 is rotatably connected to the end of the photoelectric sampling shaft 5 (such as connected by a rotating bearing) to prevent the first sensor 3 and the second sensor 4 from rotating with the photoelectric sampling shaft 5. The first sensor 3, the second sensor 4, the photoelectric sampling shaft 5 and the photoelectric sampler bracket 6 sense the sampling part. When the photoelectric sampling shaft 5 does not press on the hot-drilling 1 on the top surface of the hot-drilling pattern coil 2, the first sensor 3 and the second sensor 4 are both connected. Otherwise, the first sensor 3 and the second sensor 4 are not connected or one of them is connected. It is feasible that, in order to improve the sensing efficiency and the accuracy of the result, the first sensor 3 located on the left side of the photoelectric sampling axis 5 is turned on when the side is pressed against the hot drill 1, and similarly, the second sensor 4 on the right side of the photoelectric sampling axis 5 is turned on when the side is pressed against the hot drill 1. And when both the first sensor 3 and the second sensor 4 are turned on, it is a part of a divisible time period.

[0035] The cutter 10 and the photoelectric sampling shaft 5 are respectively arranged on both sides of the transmission component, and the cutter 10 is installed on the output end of the shearing motor. The shearing motor is connected to the single-chip microcomputer for communication. The cutter 10 is used to cut the hot-drilling pattern roll 2 during the cuttable period according to the instructions of the single-chip microcomputer to the shearing motor.

[0036] Based on the above, the automatic slitting positioning device for cutting hot-drilling patterns of the present embodiment uses the form of whether the photoelectric sampling shaft 5 presses the drill to trigger the first sensor 3 and the second sensor 4 to be connected to determine whether a cuttable position has been reached, that is, whether a non-drilling position on the hot-drilling pattern coil 2 has been reached. When the cuttable position is reached, the single-chip microcomputer controls the cutter 10 to cut the hot-drilling pattern coil 2, and direct intelligent positioning can be achieved without debugging, thereby improving the slitting efficiency.

[0037] In one embodiment, the continuous transmission assembly includes a power roller 8 and a pressure roller 9 arranged up and down, the power roller 8 is driven by a feeding motor, and the feeding motor is a driving part of the conveyor belt or rotates synchronously with the driving part of the transmission belt. Secondly, the pressure roller 9 is a silicone pressure roller.

[0038] It is feasible that the first sensor 3 and the second sensor 4 are photoelectric sensor switches or travel switches.

[0039] For the automatic slitting and positioning device for hot-drilling patterns of this embodiment, the first automatic measurement and slitting solution is: when the cutter 10 is slitting, the determination of the slitting position includes the following steps:

[0040] The time period when the first sensor 3 and the second sensor 4 are directly changed from being both turned on to being both turned off is defined as a divisible time period;

[0041] In a split time period, the position when the first sensor 3 and the second sensor 4 are fully connected for the first time is recorded as position D1;

[0042] The position when the first sensor 3 and the second sensor 4 are not fully connected for the first time is recorded as position D2;

[0043] The middle position between the position D1 and the position D2 is used as the cutting position of the cutter 10 .

[0044] Specifically, in combination with the diagram, the power roller 8 rotates clockwise, driving the hot-drilling pattern roll 2 to move to the right. When point A reaches the photoelectric sampling axis 5, the first sensor 3 and the second sensor 4 will be connected, and the single-chip computer calculates it as the starting point of the empty position. When the hot-drilling pattern roll 2 is sent to point C close to the photoelectric sampling axis 5, the first sensor 3 and the second sensor 4 will be disconnected, and the single-chip computer calculates point B in the AC distance as the center cutting position. When point B is sent to position b, the single-chip computer instructs the point B position of the hot-drilling pattern roll 2 to be cut into a hot-drilling pattern; when the hot-drilling pattern roll 2 runs to position DF, the single-chip computer determines that point E is the center cutting position based on the conduction state of the first sensor 3 and the second sensor 4, calculates it to control the cutting, and so on.

[0045] Alternatively, for the automatic slitting and positioning device for cutting hot-drilling patterns of this embodiment, the second automatic measurement and slitting solution is:

[0046] When the cutter 10 is cutting, the determination of the cutting position includes the following steps:

[0047] When length sampling learning is performed;

[0048] A preset length L of the slitting sampling is preset, and a cutting line b and a cutting line E perpendicular to the conveying direction are selected on the hot drilling pattern coil 2, wherein the cutting line b and the cutting line E are respectively located on different blocks, and the distance between the cutting line b and the cutting line E is L;

[0049] The cutting line b on the hot-drilling pattern coil 2 is conveyed to the bottom of the cutter 10, and the cutter 10 is manually operated to cut and complete the initial positioning;

[0050] The rhinestone pattern coil 2 is conveyed, and when the cutting line E on the rhinestone pattern coil 2 is conveyed to the bottom of the cutter 10, the cutter 10 is manually operated to position after the cutting is completed;

[0051] The steps of initial positioning and post-positioning are taken as the length sampling learning results, and the allowable positive and negative error values ​​are set;

[0052] During automatic slitting, the cutting position is found according to the length sampling learning result and the allowable measured positive and negative error values ​​for cyclic slitting.

[0053] It is feasible that during automatic cutting, when a preset length is reached and there are loose drills at position one that satisfies the allowable positive and negative error values, skip this position and continue to look for the next position two that reaches the preset length and satisfies the allowable positive and negative error values. When there are no loose drills at position two, use position two as the cutting position.

[0054] Specifically, combined with the diagram, if the required length to be cut is 2 blocks b and E, first send the b of the hot diamond pattern roll 2 to the cutter 10 and cut it manually, the single chip computer records the first point (i.e. the initial positioning point), and then send the hot diamond pattern roll 2 to point E, and then cut it manually. The single chip computer automatically calculates the distance bE cut by manual operation as the preset length L. This manual process is called length sampling learning. Set an allowable positive and negative error value inside the single chip computer. After the automatic cutting is started, the single chip computer searches for the next cutting position according to the above calculation scheme within the next allowable error range according to the learned preset length, and issues a cutting instruction. In this way, the hot diamond pattern material can be perfectly cut. In addition, if the machine is turned on without learning the sampling preset length, and the cutting is started directly, the single chip computer will cut according to the first automatic measurement and positioning recorded above, and the cut sheet is a single pattern. In addition, if there are extra loose diamonds in the middle of the cutting position, at this time, the sampling fails to detect the effective cutting position, and the single chip microcomputer skips a preset length and continues to detect the cutting point of the upper and lower materials of the hot-drilling pattern roll 2. At this time, the hot-drilling pattern obtained by cutting will become 2 sheets of length, and the hot-drilling pattern of the corresponding size can be obtained by manual processing.

[0055] In summary, the automatic slitting and positioning device for cutting hot-drilling patterns of this embodiment uses the form of whether the photoelectric sampling shaft 5 presses the drill to trigger whether the first sensor 3 and the second sensor 4 are connected to determine whether the cutting position is reached, that is, whether the non-drilling position on the hot-drilling pattern coil 2 is reached. When the cutting position is reached, the single-chip microcomputer controls the cutter 10 to cut the hot-drilling pattern coil 2, and direct intelligent positioning can be achieved without debugging, thereby improving the slitting efficiency. Furthermore, the functional configuration of intelligent positioning and slitting with preset size is used to improve the practicality of the device.
