Traditional injection molding factories use diagonal pliers to manually cut nozzles. However, simply relying on manual trimming of nozzles will lead to high labor costs and fatigue of workers in mass production and night shift operations.

However, the device requires manual placement of the injection molded workpieces one by one on the bearing platform for shearing, which greatly affects the work efficiency. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a nozzle shearing device which is convenient for feeding.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A water inlet shearing device is provided, comprising a stamping mechanism, a conveying mechanism, a limiting mechanism and a frame, wherein the stamping mechanism, the conveying mechanism and the limiting mechanism are all installed on the frame, and the limiting mechanism is located directly below the stamping mechanism, the conveying mechanism comprises a separation section and a feeding section connected to each other, the separation section is located between the stamping mechanism and the limiting mechanism, a channel is provided in the middle of the separation section, the channel runs through the conveying direction of the separation section, the limiting mechanism is movably connected to the frame and can pass through the channel, and the conveying speed of the separation section is greater than the conveying speed of the feeding section.

[0007] With this arrangement, when nozzle shearing is required, workers can place multiple workpieces on the feeding section of the conveying mechanism, and the workpieces move from the feeding section to the separation section. When the workpieces enter the separation section from the feeding section, because the speed of the separation section is greater than the speed of the feeding section, a gap will appear between the workpieces and they will be automatically separated. When the first workpiece reaches the bottom of the stamping mechanism, the limiting mechanism works, passes through the channel in the middle of the separation section, and extends in front of the workpiece to stop the workpiece from moving forward, thereby limiting the workpiece directly below the stamping mechanism. The stamping mechanism presses down to punch and break the nozzle material on the workpiece, and the limiting mechanism withdraws from the channel to release the limit on the workpiece. The workpiece is conveyed forward from the separation section and unloaded at the end. The feeding section of the device can also be connected to the discharge end of the injection molding machine to achieve continuous automatic feeding, greatly improving work efficiency.

[0008] Preferably, the stamping mechanism includes a turntable, a transmission rod and a stamping head arranged in sequence, and the transmission rod is also sleeved with an elastic member. It also includes a first driving mechanism arranged beside the turntable, and the first driving mechanism is eccentrically connected to the turntable. One end of the transmission rod abuts against the circumference of the turntable, and the other end of the transmission rod is fixedly connected to the stamping head, and the stamping head is located directly above the limiting mechanism. The elastic member is used to provide pressure for the transmission rod to abut against the turntable.

[0009] With this arrangement, the first drive mechanism can drive the turntable to rotate. Since the first drive mechanism is eccentrically connected to the turntable, the turntable rotates eccentrically, and the transmission rod abutting against the circumferential side of the turntable moves up and down with the eccentric rotation of the turntable, thereby controlling the punch head at the bottom of the transmission rod to perform a stamping-resetting cycle on the workpiece below.

[0010] Preferably, a rolling wheel is further provided at the end of the transmission rod abutting against the turntable, the rolling wheel is rotatably connected to the transmission rod, and the rolling wheel abuts against the peripheral side of the turntable.

[0011] Through this arrangement, the transmission rod abuts against the turntable through the rolling wheel, so that the sliding friction between the transmission rod and the turntable is converted into rolling friction, which can reduce the friction force generated by the rolling of the turntable on the transmission rod, thereby reducing the vibration of the transmission rod, which is beneficial to improving the accuracy of the stamping work and reducing the loss between the transmission rod and the turntable, thereby improving product quality and equipment life.

[0012] Preferably, a connecting platform is further provided at the end of the transmission rod connected to the punching head, the transmission rod is fixedly connected to the connecting platform, and the punching head is detachably connected to the connecting platform.

[0013] Through this setting, the connecting table can not only make the force transmitted to the punch head more uniform, avoiding equipment damage caused by long-term stress concentration, but also increase the adjustability of the equipment, making it convenient for workers to replace different models of punch heads according to different workpieces, greatly improving the applicability of the equipment.

[0014] Preferably, a guide column is further provided beside the transmission rod, the guide column is arranged parallel to the transmission rod, the guide column is movably inserted into the frame and fixedly connected to the connecting platform.

[0015] Through this arrangement, the guide column can play a limiting role, further preventing the connecting table from being displaced perpendicular to the stamping direction, and preventing the transmission rod from bearing horizontal loads alone, which is beneficial to improving working accuracy and equipment life.

[0016] Preferably, the limiting mechanism includes a mounting base and a first limiting rod, the mounting base is fixedly mounted on the frame and is located below the separation section, the first limiting rod is connected to the mounting base, and the first limiting rod is a telescopic rod structure, the first limiting rod is located directly below the punching head and can be connected to the channel on the separation section.

[0017] Furthermore, the limiting mechanism also includes a second limiting rod, which is connected to the mounting base and can also be connected to the channel on the separation section. The second limiting rod is a telescopic rod structure, and the second limiting rod is located next to the first limiting rod.

[0018] Through this arrangement, when the workpiece reaches directly below the stamping mechanism, the first limit rod and the second limit rod extend simultaneously, the first limit rod stops the workpiece directly below the stamping mechanism, and the second limit rod stops the workpiece behind from moving forward, preventing the workpiece behind from entering the working range of the stamping mechanism. When the stamping mechanism is working, the first limit rod and the second limit rod are reset, and the workpiece continues to move forward, and the above steps are repeated when the next workpiece enters under the stamping mechanism.

[0019] Preferably, the separation section includes two first mounting plates, two first rollers, a first conveyor belt and a second driving mechanism. The two first mounting plates are fixedly connected to the frame and are arranged in parallel facing each other. The channel is arranged on the first conveyor belt and located between the two first mounting plates. The two first rollers are arranged at both ends of the first conveyor belt and rotatably pass through the first mounting plates. The second driving mechanism is connected to one of the first rollers, and the first conveyor belt and the two first rollers form a belt transmission pair.

[0020] With this arrangement, the second drive mechanism can drive the first roller to rotate and thus drive the first conveyor belt to move. The workpiece is displaced by the first conveyor belt. When the workpiece reaches the bottom of the stamping mechanism, the limit mechanism extends through the channel in the middle of the first conveyor belt to stop the workpiece from moving. The stamping mechanism works to stamp and shear the workpiece, and then the limit mechanism retracts. The workpiece that has completed the water outlet shearing continues to move forward. The arrangement of the first conveyor belt here can be either a conveyor belt with a channel in the middle or two conveyor belts distributed on the left and right, with a channel naturally formed between the conveyor belts.

[0021] Furthermore, a limiting member is provided at the bottom of the channel, a guide groove is provided on the limiting member, a limiting hole is provided on the guide groove, and the first limiting rod and the second limiting rod are movably inserted into the limiting holes respectively.

[0022] Through this arrangement, when the separation section transports the workpiece, the main body of the workpiece is located on the first conveyor belt and is driven by the first conveyor belt to move forward. The water nozzle part is located on the middle guide groove. When the stamping mechanism presses down, the water nozzle part and the main body of the workpiece can be supported, which can effectively avoid the water nozzle part and the main body of the workpiece from tearing due to uneven force during stamping, thereby greatly improving the shearing process level.

[0023] Preferably, a photoelectric sensor is also provided on the guide groove, and the photoelectric sensor is arranged directly below the punching head.

[0024] Through this setting, when the workpiece moves to the position directly below the punch head, the photoelectric sensor senses the workpiece and sends a signal to make the limit mechanism and the punch mechanism work, which can further improve the accuracy of the limit and enable the device to adapt to different working rhythms.

[0025] Preferably, the loading section includes two second mounting plates, two second rollers, a second conveyor belt and a third driving mechanism. The two second mounting plates are fixedly connected to the frame and arranged in parallel facing each other. The second conveyor belt is installed between the two second mounting plates. The two second rollers are respectively arranged at both ends of the second conveyor belt and rotatably pass through the second mounting plates. The third driving mechanism is connected to one of the second rollers. The second conveyor belt and the two second rollers form a belt transmission pair, and the second conveyor belt is connected to the first conveyor belt. The workpiece can be smoothly transferred from the second conveyor belt to the first conveyor belt.

[0026] Preferably, the punch head includes a circular punch head and a four-edged parallel punch head. Through this arrangement, the user can select the corresponding punch head for installation according to the different shearing workpieces.

[0027] Compared with the prior art, the beneficial effects of the utility model are:

[0028] (1) Through the differential speed setting of the separation section and the feeding section of the conveying mechanism, low-cost, simple and practical workpiece separation is achieved, reducing the workload of the operator.

[0029] (2) It has a wide range of applications and can process different workpieces by changing different punch heads as needed.

[0030] (3) The device has a simple structure, is easy to maintain and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0041] Example 1

[0042] like Figures 1 to 3 The figure shows a first embodiment of a water nozzle shearing device of the utility model, comprising a stamping mechanism 1, a conveying mechanism 2, a limiting mechanism 3 and a frame 4. The stamping mechanism 1, the conveying mechanism 2 and the limiting mechanism 3 are all arranged on the frame 4, and the limiting mechanism 3 is located directly below the stamping mechanism 1. The conveying mechanism 2 comprises a separation section 21 and a feeding section 22 which are connected to each other. The separation section 21 is located between the stamping mechanism 1 and the limiting mechanism 3. A channel 211 is provided in the middle of the separation section 21. The channel 211 is arranged to pass through the conveying direction of the separation section 21. The limiting mechanism 3 is movably connected to the frame 4 and can pass through the channel 211. The conveying speed of the separation section 21 is greater than the conveying speed of the feeding section 22.

[0043] Through this arrangement, when nozzle shearing work is required, workers can place multiple workpieces on the loading section 22 of the conveying mechanism 2, and the workpieces move from the loading section 22 to the separation section 21. When the workpieces enter the separation section 21 from the loading section 22, because the speed of the separation section 21 is greater than the speed of the loading section 22, a gap will appear between the workpieces and they will be automatically separated. When the first workpiece arrives under the stamping mechanism 1, the limiting mechanism 3 works, passes through the separation section 21 and limits the workpiece directly under the stamping mechanism 1. The stamping mechanism 1 is pressed down to punch and break the nozzle material on the workpiece, and the limiting mechanism 3 is released. The workpiece is conveyed forward by the separation section 21 and unloaded at the end; the loading section 22 of the device can also be connected to the discharge end of the injection molding machine, so as to realize continuous automatic loading, which greatly improves work efficiency.

[0044] As an embodiment of the utility model, the stamping mechanism 1 includes a turntable 12, a transmission rod 13 and a punching head 14 arranged in sequence, and an elastic member 15 is also sleeved on the outside of the transmission rod 13. It also includes a first driving mechanism 11 arranged beside the turntable 12, and the first driving mechanism 11 is eccentrically connected to the turntable 12. One end of the transmission rod 13 abuts against the peripheral side of the turntable 12, and the other end of the transmission rod 13 is fixedly connected to the punching head 14, and the punching head 14 is located directly above the limiting mechanism 3. The elastic member 15 is used to provide pressure for the transmission rod 13 to abut against the turntable 12.

[0045] With this arrangement, the first drive mechanism 11 can drive the turntable 12 to rotate. Since the first drive mechanism 11 is eccentrically connected to the turntable 12, the turntable 12 rotates eccentrically, and the transmission rod 13 abutting against the circumferential side of the turntable 12 moves up and down with the eccentric rotation of the turntable 12, thereby controlling the punch head 14 at the bottom of the transmission rod 13 to perform a stamping-resetting cycle on the workpiece below.

[0046] As an embodiment of the present invention, a rolling wheel 16 is further provided at the end of the transmission rod 13 abutting against the turntable 12 . The rolling wheel 16 is rotatably connected to the transmission rod 13 , and the rolling wheel 16 abuts against the peripheral side of the turntable 12 .

[0047] With this arrangement, the transmission rod 13 abuts against the turntable 12 via the rolling wheel 16, so that the sliding friction between the transmission rod 13 and the turntable 12 is converted into rolling friction, which can reduce the friction force generated by the rolling of the turntable 12 on the transmission rod 13, thereby reducing the vibration of the transmission rod 13, which is beneficial to improving the accuracy of the stamping work and reducing the loss between the transmission rod 13 and the turntable 12, thereby improving product quality and equipment life.

[0048] As an embodiment of the present utility model, a connecting platform 17 is further provided at the end where the transmission rod 13 and the punch head 14 are connected. The transmission rod 13 and the connecting platform 17 are fixedly connected, and the punch head 14 and the connecting platform 17 are detachably connected.

[0049] Through this setting, the connecting platform 17 can make the force transmitted to the punch head 14 more uniform, avoiding equipment damage caused by long-term stress concentration, and increase the adjustability of the equipment, making it convenient for workers to replace different models of punch heads 14 according to different workpieces, greatly improving the applicability of the equipment.

[0050] As an embodiment of the present utility model, a guide column 18 is further provided beside the transmission rod 13 . The guide column 18 is arranged parallel to the transmission rod 13 . The guide column 18 is movably inserted into the frame 4 and fixedly connected to the connecting platform 17 .

[0051] With this arrangement, the guide column 18 can play a limiting role, further preventing the connecting platform 17 from being displaced perpendicular to the stamping direction, and preventing the transmission rod 13 from bearing horizontal loads alone, which is beneficial to improving working accuracy and equipment life.

[0052] As an embodiment of the utility model, the limiting mechanism 3 includes a mounting base 31, a first limiting rod 32 and a second limiting rod 33. The first limiting rod 32 and the second limiting rod 33 are both connected to the mounting base 31 and are passed through the separation section 21. The first limiting rod 32 and the second limiting rod 33 are both telescopic rod structures. The first limiting rod 32 is located directly below the punching head 14, and the second limiting rod 33 is located beside the first limiting rod 32. The first limiting rod 32 and the second limiting rod 33 can extend through the channel 211.

[0053] Through this arrangement, when the workpiece reaches directly below the stamping mechanism 1, the first limit rod 32 and the second limit rod 33 extend simultaneously, the first limit rod 32 stops the workpiece directly below the stamping mechanism 1, and the second limit rod 33 stops the workpiece behind from moving forward, thereby preventing the workpiece behind from entering the working range of the stamping mechanism 1. When the stamping mechanism 1 is working, the first limit rod 32 and the second limit rod 33 are reset, and the workpiece continues to move forward, and the above steps are repeated when the next workpiece enters below the stamping mechanism 1.

The channel 211 is arranged on the first conveyor belt 214 and is located between the two first mounting plates 212. The two first rollers 213 are arranged at both ends of the first conveyor belt 214 and are rotatably passed through the first mounting plates 212. The second driving mechanism 215 is connected to one of the first rollers 213. The first conveyor belt 214 and the two first rollers 213 form a belt transmission pair.

[0057] Through this arrangement, the second driving mechanism 215 can drive the first roller 213 to rotate and thereby drive the first conveyor belt 214 to move. The workpiece is driven to move by the first conveyor belt 214. When the workpiece reaches the bottom of the stamping mechanism 1, the limiting mechanism 3 extends through the channel 211 in the middle of the first conveyor belt 214 to stop the workpiece from moving. The stamping mechanism 1 works to stamp and shear the workpiece, and then the limiting mechanism 3 retracts, and the workpiece that has completed the water outlet shearing continues to move forward.

[0058] As an embodiment of the present invention, a limiting member is provided at the bottom of the channel 211, a guide groove is provided on the limiting member 216, a limiting hole is provided on the guide groove, and the first limiting rod 32 and the second limiting rod 33 are movably provided in the limiting holes.

The water nozzle part is located on the middle guide groove. When the stamping mechanism 1 is pressed down, the water nozzle part and the main body of the workpiece can be supported, which can effectively avoid the water nozzle part and the main body of the workpiece from tearing due to uneven force during stamping, thereby greatly improving the shearing process level.

[0064] As an embodiment of the present invention, a photoelectric sensor 217 is further provided on the limiting member 216 , and the sensor is arranged directly below the punching head 14 .
