The blanking mechanism comprises an equipment table, a baffle, a driving part, a mounting part, a swinging block and a sensor, and through the movement of the baffle plate, the baffle plate can be switched between blocking the through groove and not blocking the through groove. The baffle blocks the through groove, and the rubber strip can move in the through groove until the rubber strip completely enters the through groove. In the process, the rubber strip in the through groove firstly abuts against the lower portion of the swing block and then continues to move by a certain distance to drive the swing block to swing, so that the sensor is triggered, and the driving part is controlled to drive the baffle to do opening and closing movement once. More specifically, the opening and closing movement is that the baffle does not block the through groove after being opened, keeps for a certain time and then recovers to be closed to block the through groove. The baffle does not block the through groove, and the adhesive tape in the groove falls down from the through groove and enters the material receiving box. The adhesive tape collecting device has the beneficial effects that the structure is simple, and adhesive tapes falling into the material collecting box are neater and more convenient to collect.

[0002] Generally, the raw material particles are fed into an extruder, and then continuously extruded by the extruder through a corresponding die. Under the action of a traction device, the extruded rubber strip is cooled and shaped by a cooling device, and then cut into a desired length by a cutting device. The cut rubber strip needs to be collected. At present, the cut rubber strip is usually moved forward by the rubber strip pulled from behind, so that the cut rubber strip can be continuously moved to a collection station, and then collected by manual work at the collection station. SUMMARY

[0003] The present application provides a discharging mechanism of rubber strip, which can solve the problem of inconvenient collection of cut rubber strip in the production and processing of rubber strip.

[0004] In the present application, a discharging mechanism of rubber strip is provided, which comprises:

[0005] A device table, the table top has a long slot, and a receiving box is arranged below the table top;

[0006] A baffle is movably connected to the bottom surface of the table top;

[0007] A driving part is used to drive the baffle to move, so that the baffle can be switched between blocking the slot and not blocking the slot;

[0008] An installation part is fixedly connected to the table top;

[0009] A swing block is hingedly connected to the installation part in the middle, and the lower part enters the slot, and is used to drive the swing block to swing by the movement of the rubber strip in the slot;

[0010] A sensor is installed on the installation part and connected to the driving part, and is triggered by the swing of the upper part of the swing block.

[0011] In some embodiments, the installation part can be adjusted along the long side of the slot at a fixed position of the device table.

[0012] In some embodiments, the movable connection between the baffle and the device table is a hinge.

[0013] In some embodiments, the installation part is embedded with a magnet for adsorbing the table top.

[0014] In some embodiments, the driving part is a plurality of cylinders; the bottom surface of the table top is fixed with a downward extension; the cylinder body is hinged to the extension, and the piston rod is hinged to the baffle; during the movement of the baffle, the hinging point of the cylinder body on the extension remains lower than the hinging point of the piston rod on the baffle.

[0015] In some embodiments, the table top is further provided with a scale for indicating length along the long side of the through slot.

[0016] In summary, in the present application, a cutting mechanism for rubber strip includes a device table, a baffle, a driving part, a mounting part, a swing block and a sensor. The baffle can be switched between blocking the through slot and not blocking the through slot by the movement of the baffle. When the baffle blocks the through slot, the rubber strip can move in the through slot until the rubber strip completely enters the through slot. In this process, the rubber strip in the through slot first abuts against the lower part of the swing block and then moves a distance, causing the swing block to swing and thus triggering the sensor to control the driving part to drive the baffle to make an opening and closing movement. More specifically, the opening and closing movement is as follows: after the baffle is opened and does not block the through slot, it is kept for a certain period of time and then restored to be closed to block the through slot. When the baffle does not block the through slot, the rubber strip in the groove falls from the through slot and enters the receiving box. The structure is simple, and the rubber strips falling into the receiving box are more orderly and more convenient to collect. BRIEF DESCRIPTION OF DRAWINGS

[0030] Referring to Figure 1 A cutting mechanism of a rubber strip includes a device table 1, a baffle 2, a driving part 3, a mounting part 4, a swing block 5, and a sensor 6.

[0031] The table top 1b of the device table 1 has a long slot 1b1, and the device table 1 has a receiving box 1c below the table top 1b. More specifically, the device table 1 can include a frame 1a built by a profile and a table top 1b fixedly connected to the top of the frame 1a, and the receiving box 1c can be inserted / extracted from the frame 1a.

[0032] Referring to Figure 2 The baffle 2 is movably connected to the bottom surface of the table top 1b, and the movable connection can be horizontal movement or hinged. Through the movement of the baffle 2, the baffle 2 can be switched between blocking the slot 1b1 and not blocking the slot 1b1. First, the baffle 2 blocks the slot 1b1, and the rubber strip can move in the slot 1b1 until the rubber strip completely enters the slot 1b1; then, the baffle 2 is switched to not block the slot 1b1, and the rubber strip in the groove falls from the slot 1b1 and enters the receiving box 1c.

[0033] Referring to Figure 3, preferably, the movable connection between the baffle 2 and the equipment table 1 is a hinge. More specifically, the two parts can be connected using a hinge. When the baffle 2 does not block the through slot 1b1, the inclination angle of the baffle 2 can be designed so that the rubber strip falling from the through slot 1b1 can enter the receiving box 1c along the inclined baffle 2.

[0034] The driving part 3 is used to drive the baffle 2 to move, so that the baffle 2 can switch between blocking the through slot 1b1 and not blocking the through slot 1b1.

[0035] Please refer to Figure 3 In some embodiments, based on the above-mentioned embodiment of "the movable connection between the baffle 2 and the equipment table 1 is a hinge", the driving part 3 is a plurality of air cylinders. The bottom surface of the table 1b is fixed with a downward extension 1b2. The cylinder body of these air cylinders is hinged to the extension 1b2, and the piston rod is hinged to the baffle 2. During the movement of the baffle 2, the hinge point of the cylinder body on the extension 1b2 is kept lower than the hinge point of the piston rod on the baffle 2.

[0036] When the baffle 2 blocks or does not block the through slot 1b1, a triangular structure is formed between the air cylinder, the baffle 2 and the table 1b, so that the baffle 2 remains stable.

[0037] Please refer to Figure 2 The mounting part 4 is fixedly connected to the table 1b.

[0038] The middle part of the swing block 5 is hinged to the mounting part 4, and the lower part enters the through slot 1b1. When the rubber strip in the through slot 1b1 moves and abuts against the lower part of the swing block 5, it can drive the swing block 5 to swing.

[0039] The sensor 6 is installed on the mounting part 4 and connected to the driving part 3, that is, the movement of the driving part 3 is controlled through the sensor 6. In combination with the above-mentioned embodiment of "the driving part 3 is a plurality of air cylinders", the sensor 6 and the driving part 3 can use PLC.

[0040] The sensor 6 is triggered by the swing of the upper part of the swing block 5. More specifically, the sensor 6 can use inductance; a three-position reversing valve can be used in the air path of the cylinder and air pump, and the spool is controlled by the electromagnet 4a on both sides of the valve body; when one side is powered, the piston rod of the cylinder extends; when the other side is powered, the piston rod of the cylinder retracts; when neither side is powered, the piston rod of the cylinder remains in the current state; the PLC controls the two electromagnets 4a: the sensor 6 has no signal, the piston rod of the cylinder remains extended, and the baffle 2 blocks the through slot 1b1; the rubber strip in the through slot 1b1 moves, driving the swing block 5 to swing, the sensor 6 generates a signal and inputs the PLC, which is programmed to convert the signal one into a continuous signal two, and the PLC is programmed to use a timer to make the piston rod of the cylinder retract first and remain for a certain period of time, driving the baffle 2 to switch to not block the through slot 1b1 for the rubber strip to fall, and then the piston rod re-extends and remains, driving the baffle 2 to reset while resetting the signal two.

[0041] Please refer to Figure 3 and Figure 4 In some embodiments, the mounting portion 4 can be adjusted along the long side of the through slot 1b1 to a fixed position of the equipment table 1.

[0042] Adjusting the position of the mounting portion 4 also adjusts the position of the swing block 5, which can be applied to rubber strips of different lengths.

[0043] Preferably, the adjustment between the mounting portion 4 and the equipment table 1 can be that the mounting portion 4 is embedded with a magnet 4a for adsorbing the table top 1b. More specifically, the table top 1b is fixedly connected with a first mounting strip along one side of the long side of the through slot 1b1, the first mounting strip has a convex slot 1d1 for the mounting portion 4 to insert and slide, and the material of the first mounting strip can be adsorbed by the magnet 4a. That is, by using a suitable magnet 4a and pushing the mounting portion 4, the mounting portion 4 can slide along the convex slot 1d1, and after stopping, the magnet 4a adsorbs the first mounting strip and is fixed relative to the first mounting strip.

[0044] Please refer to Figure 2 and Figure 4 In some embodiments based on the above-mentioned embodiment that the mounting portion 4 can be adjusted along the long side of the through slot 1b1 to a fixed position of the equipment table 1, the table top 1b is also provided with a scale for indicating length along the long side of the through slot 1b1. More specifically, the table top 1b is fixedly connected with a second mounting strip along the other side of the long side of the through slot 1b1, and the scale is provided on the second mounting strip.

[0045] It can be more convenient to adjust the mounting portion 4 to the appropriate position according to the length of the rubber strip.
