Description

Technical Field

[0001] The invention belongs to the technical field of injection molding, and in particular relates to a material strip breaking machine for injection molding parts. Background Art

[0002] The injection molded parts used in electronic products are relatively small in size. Usually, multiple injection molds are connected by runners for one-time injection molding. The completed injection molded parts together with the runner parts form an injection molded parts strip, which needs to be separated. The existing separation operation is either performed manually or by using ultrasonic vibration. The former has the disadvantage of low work efficiency, and the latter may not ensure that the injection molded parts on the strip are separated at one time, resulting in subsequent secondary operations, and the high-frequency vibration of the ultrasonic wave may cause damage to the inside of the injection molded parts.

[0003] A Chinese patent application with authorization announcement number CN219133112U discloses a nozzle processing device for injection molded parts, which has the following advantages or beneficial effects: a manipulator mechanism, a high-frequency mechanism and a slide mechanism are arranged on a frame, and the injection molded parts to be processed can be automatically grabbed onto the slide mechanism by the manipulator mechanism, and then the injection molded parts are laterally transported to the nozzle processing area of ​​the high-frequency mechanism by the slide mechanism. After the high-frequency mechanism is started, the nozzle of the injection molded part is broken by ultrasound, thereby separating the sprue from the injection molded product, and the separated injection molded product will automatically fall into the injection molded product blanking collection frame for collection. At the same time, the slide mechanism drives the sprue remaining on the slide mechanism to return to the material picking and placing area, and the sprue is transferred to the waste collection frame by the manipulator mechanism, thereby realizing the automatic separation of the injection molded product and the sprue of the injection molded part. It has a high degree of automation, which is beneficial to reducing the labor intensity of workers and improving the nozzle processing efficiency of injection molded parts.

[0004] However, this technical solution still has at least the following defects: the high-frequency mechanism in this solution still separates by ultrasonic vibration, and still cannot ensure all separation at one time, and in this solution, a robot is required to grab the injection molded parts onto the slide mechanism, which is redundant in operation and increases the economic burden of the robot. In view of this, the present invention is proposed. Summary of the invention

The following embodiments are used to illustrate the present invention.

[0045] Example 1

[0046] like Figures 1 to 13 As shown, the injection molding strip breaking machine includes:

[0047] The conveying unit includes an upper conveying mechanism and a lower conveying mechanism. The upper conveying mechanism includes a conveyor belt 109, and main rollers 103 are installed at both ends of the conveyor belt 109, and a power device 110 is installed at one end of one of the main rollers 103. The lower conveying mechanism includes a support frame 200, and a conveyor chain 201 is installed outside the support frame 200. The conveying unit presses the injection molding material belt through the conveyor belt 109 and the conveyor chain 201, and drives the conveyor belt 109 for conveying through the power device 110;

[0048] The power unit 110 adopts a permanent magnet assisted synchronous reluctance motor, which has the characteristics of low speed and high torque.

[0049] A breaking unit, the breaking unit comprises a first guide rod 301 and a second guide rod 303, the first guide rod 301 is provided with a first guide section 302, the second guide rod 303 is provided with a second guide section 304, and the breaking unit causes the injection molded part to be displaced relative to the material strip through the first guide section 302 and the second guide rod 303;

[0050] A cutting unit, the cutting unit comprises a mounting block 504, a cutter 505 is mounted on the mounting block 504, and the cutting unit cuts the material strip by the cutter 505;

[0051] The cutter 505 is set at a 45 degree angle to the moving direction of the injection molding material strip, so that when the cutter 505 cuts the injection molding material strip at any position, it can avoid the difficulty of cutting caused by excessive contact between the injection molding material strip and the cutter 505.

[0052] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in a specific embodiment, the upper conveying mechanism further includes a base 101, and base plates 102 are fixedly mounted at the bottom of both ends of the base 101, and the main roller 103 is rotatably connected to the base plate 102. A pressing component is provided on the conveyor belt 109, and the pressing component is used to provide pressure to maintain the clamping force of the upper conveying mechanism and the lower conveying mechanism on the injection molding material belt;

[0053] The lower conveying mechanism also includes a locking assembly, which includes a cam 202 and a locking ring 204. The cam 202 is rotatably connected to one end of the support frame 200. A groove 205 is provided at the bottom of the locking ring 204. The locking assembly makes the lower conveying mechanism fit the upper conveying mechanism through the cam 202 and the locking ring 204.

[0054] In this arrangement, when the support frame 200 is fitted with the upper conveying mechanism through the locking assembly, the pressing assembly acts on the conveyor belt 109 to press the conveyor belt 109 against the injection molded part material belt.

[0055] like Figure 1 , Figure 2 As shown, further, the pressing assembly includes a support block 104, the top of the support block 104 is fixedly mounted on the bottom of the base 101, a first telescopic rod 105 is fixedly mounted on the bottom of the support block 104, a connecting frame 107 is fixedly mounted on the bottom of the first telescopic rod 105, a secondary roller 108 is rotatably mounted on the end of the connecting frame 107, the secondary roller 108 is adapted to the conveyor belt 109, and a first spring 106 is movably sleeved on the first telescopic rod 105. In this configuration, the secondary roller 108 is pressed against the conveyor belt 109, so that the pressing assembly can reduce friction resistance while applying pressure, and at the same time, the elasticity of the first telescopic rod 105 and the first spring 106 enables the pressing assembly to change adaptively, so that the conveyor belt 109 better fits the injection molding material belt.

[0056] like Figure 4 , Figure 5 As shown, further, the locking assembly also includes a fixed plate 206, one end of the fixed plate 206 is fixedly connected to the lock ring 204, a movable frame 207 is movably sleeved on the outer side of the fixed plate 206, a return spring 208 is installed between the movable frame 207 and the fixed plate 206, a base frame 100 is fixedly installed on one side of the base 101, one end of the fixed plate 206 is fixedly installed on one side of the base frame 100, a starter 111 is also fixedly installed on one side of the base frame 100, the starter 111 is used to start the power device 110, and a pressure plate 209 is fixedly installed on the top of the movable frame 207, and the pressure plate 209 is aligned with the starter 111. In this setting, the starter 111 is electrically connected to the power device 110, and the cam 202 rotates while resisting the movable frame 207 and driving it to move, and the movable frame 207 drives the pressure plate 209 to move and triggers the starter 111, and the power device 110 works at this time, wherein a handle 203 is installed on one side of the cam 202 for driving the cam 202 to rotate.

[0057] Example 2

[0058] like Figure 2 , Figure 3 , Figure 7As shown, in a specific embodiment, a fixed block 300 is fixedly installed at one end of the base 101, and the first guide rod 301 and the second guide rod 303 are both fixedly installed on one side of the fixed block 300. A pressure wheel 305 is arranged on the top of the first guide rod 301, and the pressure wheel 305 is coaxially fixedly connected with the main roller 103. A rotating transmission mechanism is arranged at the bottom of the fixed block 300, and the rotating transmission mechanism includes a plug plate 407, and the plug plate 407 is rotatably connected to the fixed block 300, and a tooth plate 406 is fixedly installed at one end of the plug plate 407, and a limiting frame 210 is fixedly installed at one end of the support frame 200, and the limiting frame 210 is adapted to the plug plate 407. In this arrangement, when the injection molded part strip moves to the pressure wheel 305, the pressure wheel 305 pushes the injection molded part downward, causing the injection molded part to bend relative to the strip. At this time, a break appears at the connection between the injection molded part and the strip. The bent injection molded part enters the first guide rod 301 and the second guide rod 303, and is separated from the strip under the guidance of the first guide section 302 and the second guide section 304. At this time, the injection molded part falls directly, and the strip continues to move.

[0059] like Figure 8 , Fig.13 As shown, further, a clamping mechanism is provided on one side of the fixed block 300, and the clamping mechanism includes a first pressure roller 400 and a second pressure roller 401. Both ends of the first pressure roller 400 are rotatably connected to the fixed block 300, and gears 405 are fixedly installed at both ends of the first pressure roller 400, and the gears 405 are adapted to the toothed plate 406. The fixed block 300 is located at the bottom of the first pressure roller 400 and is fixedly installed with an insertion rod 403, and a connecting block 402 is movably sleeved on the insertion rod 403. The second pressure roller 401 is rotatably connected to the connecting block 402, and a tension spring 404 is movably sleeved on the insertion rod 403, and both ends of the tension spring 404 are respectively fixedly connected to the fixed block 300 and the connecting block 402. In this configuration, V-shaped grooves are provided on the surfaces of the first pressing roller 400 and the second pressing roller 401, and the friction between the first pressing roller 400 and the second pressing roller 401 can be increased through the V-shaped grooves. When the injection molded part falls completely, the support frame 200 is rotated downward, and the insert plate 407 is driven to rotate through the limiting frame 210, and the insert plate 407 drives the tooth plate 406 to rotate. The tooth plate 406 drives the gear 405 to rotate through meshing, and the gear 405 drives the first pressing roller 400 to rotate, thereby withdrawing the material strip pressed between the first pressing roller 400 and the second pressing roller 401.

[0060] like Fig. 9 , Fig.10 , Fig.11As shown, further, the cutting unit also includes a mounting plate 500, a slide bar is mounted on the side of the mounting plate 500, and the mounting block 504 is movably sleeved on the slide bar. The cutting unit also includes a reset mechanism and a closing mechanism. The reset mechanism is located at the upper and lower sides of the cutter 505, and the closing mechanism is located at both sides of the mounting plate 500. The cutting unit controls the cutting action of the cutter 505 through the closing mechanism, and controls the opening of the cutter 505 through the reset mechanism. In this setting, the cutting of the material strip by the cutter 505 is achieved through the dual effects of the closing mechanism and the reset mechanism.

[0061] like Fig. 9 , Fig.10 , Fig.11 As shown, further, the reset mechanism includes a support plate 501, both ends of the support plate 501 are fixedly connected to the mounting plate 500, a second telescopic rod 502 is fixedly installed on the support plate 501, a second spring 503 is movably sleeved on the second telescopic rod 502, one end of the second telescopic rod 502 is fixedly connected to the mounting block 504, and the closing mechanism includes a guide ring 507, a guide bevel 508 is provided on the inner wall of the guide ring 507, a guide column 506 is fixedly installed on the end of the mounting block 504, the guide column 506 is adapted to the guide bevel 508, and a transmission assembly is arranged between the guide ring 507 and the pressure wheel 305, and the transmission assembly is used to transmit the conveying unit and the cutting unit. In this arrangement, the guide ring 507 drives the guide column 506 to move through the guide bevel 508, thereby driving the mounting block 504 to move. When the guide bevel 508 and the guide column 506 are offset, the second spring 503 drives the mounting block 504 to reset to achieve the reciprocating motion of the mounting block 504, and drives the cutter 505 to move by driving the reciprocating motion of the mounting block 504 to cut off the material strip.

[0062] like Figure 1 , Figure 7 As shown, further, the transmission assembly includes a first sprocket 509 and a second sprocket 511, the first sprocket 509 is fixedly connected to the guide ring 507, the second sprocket 511 is fixedly connected to the pressure wheel 305, and a chain 510 is meshed and connected between the first sprocket 509 and the second sprocket 511. In this configuration, when the pressure wheel 305 rotates, the second sprocket 511 drives the first sprocket 509 to rotate through the chain 510, and the first sprocket 509 drives the guide ring 507 to rotate.

[0063] The implementation principle of the injection molding strip breaking machine of this embodiment is as follows: when in use, the injection molding strip can be pre-placed on the conveyor chain 201 on the support frame 200, and the limit frame 210 at one end of the support frame 200 is aligned with the plug plate 407, and the support frame 200 is rotated to make it fit the bottom of the conveyor belt 109. At this time, the conveyor belt 109 presses the injection molding strip on the support frame 200 under the action of the first spring 106, and at the same time, the cam 202 at one end of the support frame 200 enters the locking ring 204 through the groove 205, and the handle 203 is rotated, and the handle 203 drives the cam 202 to rotate, so that the cam 202 cannot cooperate with the groove 205, and the support frame 200 is installed and fixed;

[0064] The cam 202 rotates while pressing against the movable frame 207 and drives it to move. The movable frame 207 drives the pressure plate 209 to move and triggers the starter 111. At this time, the power device 110 works and drives the conveyor belt 109 to rotate through the main roller 103 connected thereto, thereby driving the injection molded part material belt to move. When the conveyor belt 109 rotates, it drives the pressure wheel 305 to rotate through another main roller 103. When the injection molded part material belt moves to the pressure wheel 305, the pressure wheel 305 pushes the injection molded part downward, so that the injection molded part is bent relative to the material belt. At this time, a fracture mark appears at the connection between the injection molded part and the material belt. After being bent, the injection molded part enters the first guide rod 301 and the second guide rod 303, and is separated from the material belt under the guidance of the first guide section 302 and the second guide section 304. At this time, the injection molded part falls directly, and the material belt continues to move.

[0065] The material strip continues to move to the first pressing roller 400 and pushes the second pressing roller 401 away to be inserted between the first pressing roller 400 and the second pressing roller 401. Under the action of the tension spring 404, the first pressing roller 400 and the second pressing roller 401 clamp the material strip so that it cannot move.

[0066] When the pressing wheel 305 rotates, it drives the second sprocket 511 to rotate. The second sprocket 511 drives the first sprocket 509 to rotate through the chain 510. The first sprocket 509 drives the guide ring 507 to rotate. The guide ring 507 drives the guide column 506 to move through the guide inclined surface 508, thereby driving the installation block 504 to move. When the guide inclined surface 508 and the guide column 506 are offset, the second spring 503 drives the installation block 504 to reset to achieve the reciprocating motion of the installation block 504. The reciprocating motion of the installation block 504 drives the cutter 505 to move, thereby cutting the material strip.

[0067] When the injection molded part falls completely and the material belt is separated from the conveyor belt 109, the cam 202 is reset and aligned with the groove 205. At this time, the reset spring 208 drives the movable frame 207 to reset, thereby closing the starter 111, rotating the support frame 200 downward, and driving the plug plate 407 to rotate through the limit frame 210, and the plug plate 407 drives the tooth plate 406 to rotate. The tooth plate 406 drives the gear 405 to rotate through meshing, and the gear 405 drives the first pressure roller 400 to rotate, thereby pushing out the material belt pressed between the first pressure roller 400 and the second pressure roller 401.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
