Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and specifically to a vacuum feeding device. Background Technology

[0002] Plastic boxes are a type of packaging box, referring to product outer packaging boxes made of plastic sheets through a series of processes such as printing, die-cutting, and gluing. Compared to traditional cardboard boxes and other packaging, plastic boxes have advantages such as being environmentally friendly, non-toxic, highly transparent, and allowing for a more intuitive display of the packaged product.

[0003] In the production process of plastic boxes, plastic sheets need to be fed. Traditional feeding devices have only one feeding station, which results in low work efficiency.

Currently, the feeding brackets of the feeding device are all placed in a flat state.

[0055] The present invention will be further described in conjunction with the following embodiments.

[0056] Depend on Figures 1 to 8As can be seen, the vacuum feeding device described in this embodiment includes a base 1; the base 1 is provided with a first feeding device, a second feeding device, and a vacuum transmission device; the first feeding device and the second feeding device are used to transport materials to the vacuum transmission device; the vacuum transmission device is used to transfer the materials of the first feeding device and the materials of the second feeding device to the outside.

[0057] The first feeding device includes a first support 22 and a first lifting mechanism for driving the first support 22 to rise and fall; the second feeding device includes a second support 28 and a second lifting mechanism 21 for driving the second support 28 to rise and fall.

[0058] Both the first lifting mechanism and the second lifting mechanism 21 are provided with a tilt adjustment mechanism for adjusting the tilt of the first support 22 and the second support 28;

[0059] The vacuum transmission device includes a suction cup shaft 312 rotatably mounted on the base 1, a vacuum nozzle 321 mounted on the suction cup shaft 312, and a cam-linkage mechanism for driving the suction cup shaft 312 to move.

[0060] Specifically, the vacuum feeding equipment described in this embodiment, by setting a first feeding device and a second feeding device on the base 1 respectively, and by setting a first lifting mechanism and a second lifting mechanism 21 respectively to independently control the lifting of the first support 22 and the second support 28, can independently raise the plastic box sheet of the first support 22 and the plastic box sheet of the second support 28 to the position of the vacuum transmission mechanism. The cam linkage mechanism then drives the suction cup shaft 312 and the vacuum nozzle 321 to work and transfer the sheet material one by one to the external equipment, thereby completing the feeding of the plastic box sheet. By setting a first feeding device and a second feeding device that can work independently, the feeding efficiency is greatly improved. In addition, by setting a tilt adjustment mechanism, the tilt angle of the first support 22 and the second support 28 can be adjusted, thereby adjusting the tilt angle of the plastic box sheet.

[0061] The vacuum feeding device described in this embodiment includes a first lifting mechanism and a second lifting mechanism 21, each comprising a first screw 231, a second screw 251, a first nut seat 232, a second nut seat 252, a linkage assembly, and a screw drive assembly for driving the first screw 231 to rotate; the tilt adjustment mechanism includes a clutch 27.

[0062] Both the first screw 231 and the second screw 251 are rotatably mounted on the base 1; the first nut seat 232 and the second nut seat 252 are respectively sleeved on the first screw 231 and the second screw 251; the first nut seat 232 and the second nut seat 252 are respectively connected to the two ends of the first bracket 22 or the two ends of the second bracket 28; the first screw 231 is connected to one end of the linkage assembly; the other end of the linkage assembly is connected to the second screw 251 through the clutch 27.

[0063] Specifically, when no angle adjustment is needed, the clutch 27 causes the second screw 251 to be linked with the first screw 231 through the linkage assembly. Therefore, while the screw drive assembly drives the first screw 231 to rotate, the second screw 251 rotates synchronously with the first screw 231, thereby causing the first nut seat 232 and the second nut seat 252 to rise and fall synchronously, thus driving the plastic box sheet on the first bracket 22 or the second bracket 28 to rise and fall for loading. When it is necessary to adjust the tilt angle of the first bracket 22 or the second bracket 28, the clutch 27 causes the second screw 251 to separate from the linkage assembly. At this time, when the screw drive assembly drives the first screw 231 to rotate, the second screw 251 will not rotate. That is, at this time, the first nut seat 232 can be adjusted to rise and fall independently, thereby changing the relative position of the first nut seat 232 and the second nut seat 252, thereby adjusting the tilt angle of the first bracket 22 or the second bracket 28, that is, adjusting the tilt angle of the plastic box sheet.

[0064] The vacuum feeding device described in this embodiment includes a screw drive assembly comprising a lifting motor 241 mounted on a base 1, a first lifting synchronous pulley 242 connected to the output end of the lifting motor 241, a second lifting synchronous pulley 243 connected to a first screw 231, and a first lifting synchronous belt 244 sleeved between the first and second lifting synchronous pulleys 243.

[0065] Specifically, when the first screw 231 is driven to rotate, the lifting motor 241 works, driving the first screw 231 to rotate through the first lifting synchronous pulley 242, the first lifting synchronous belt 244 and the second lifting synchronous pulley 243, thereby causing the first nut seat 232 to rise or fall.

[0066] The linkage assembly includes a third lifting synchronous pulley 261 connected to the first screw 231, a fourth lifting synchronous pulley 262 connected to the clutch 27, and a second lifting synchronous belt 263 disposed between the third lifting synchronous pulley 261 and the fourth lifting synchronous pulley 262; the second screw 251 is connected to the fourth lifting synchronous pulley 262 through the clutch 27.

[0067] Specifically, when the first screw 231 rotates, the first screw 231 drives the second screw 251 to rotate through the third lifting synchronous wheel 261, the second lifting synchronous belt 263 and the fourth lifting synchronous wheel 262. At the same time, the first screw 231 and the second screw 251 rotate in the same direction, so that the second nut seat 252 and the first nut seat 232 can rise and fall synchronously, so that the first bracket 22 or the second bracket 28 can rise and fall more stably.

[0068] In this embodiment of the vacuum feeding equipment, both the first lifting mechanism and the second lifting mechanism 21 include a first guide rod 233 arranged parallel to the first screw 231; the first guide rod 233 is disposed on the machine base 1; the first nut seat 232 is provided with a first guide block 234 slidably connected to the first guide rod 233.

[0069] Specifically, by setting the first guide rod 233 and the first guide block 234, the structure of the first lifting mechanism is made more stable, enabling the first bracket 22 and the second bracket 28 to lift stably.

[0070] The second lifting mechanism 21 also includes a second guide rod 253 arranged parallel to the second screw 251; the second guide rod 253 is disposed on the base 1; the second nut seat 252 is provided with a second guide block 254 slidably connected to the second guide rod 253;

[0071] In this embodiment, a vacuum feeding device is provided in which the first screw 231 and the second screw 251 are arranged in parallel.

[0072] Specifically, by setting the second guide rod 253 and the second guide block 254, the structure of the second lifting mechanism 21 is made more stable, enabling the first support 22 and the second support 28 to lift stably.

[0073] Bearings are provided between the first screw 231 and the base 1, and between the second screw 251 and the base 1; the above arrangement enables the first screw 231 and the second screw 251 to rotate on the base 1.

[0074] The base 1 is provided with a support base 11 at its bottom; the support base 11 is detachably connected to the base 1; the above arrangement enables the base 1 to be placed stably on the ground.

[0075] The base 1 is equipped with casters 12 at its bottom. This arrangement facilitates the movement of the base 11.

[0076] The vacuum feeding device described in this embodiment further includes a sliding rod 13 slidably disposed on a base 1; a pressure nozzle 14 is provided on the sliding rod 13; and an induction switch 15 is provided on the base 1.

[0077] Specifically, by setting the sliding rod 13 and the pressing air nozzle 14, the pressing air nozzle 14 can press the plastic box sheet on the first feeding device and the second feeding device to prevent the next plastic box sheet from slipping off when the vacuum transmission device is adsorbing the plastic box sheet on the top surface; by setting the induction switch 15, the height of the first support 22 and the second support 28 can be controlled.

[0078] The vacuum feeding device described in this embodiment includes a cam linkage mechanism comprising a camshaft 311 rotatably mounted on a base 1, a cam drive mechanism for driving the camshaft 311 to rotate, a moving mechanism for driving the camshaft 311 to move, and a rotating mechanism for driving the camshaft 311 to rotate.

[0079] The moving mechanism includes a horizontal link 331 and a first cam 33 for driving the horizontal link 331 to swing; the first cam 33 is mounted on a camshaft 311; one end of the horizontal link 331 is rotatably connected to the base 1; the other end of the horizontal link 331 is rotatably connected to the camshaft 311; wherein the horizontal link 331 is connected to the camshaft 311 through a bearing.

[0080] The rotating mechanism includes a vertical connecting rod 343, a first connecting rod 341, a second connecting rod 342, and a second cam 34 for driving the vertical connecting rod 343 to swing; the second cam 34 is mounted on a camshaft 311; one end of the vertical connecting rod 343 is hinged to one end of the first connecting rod 341; the other end of the first connecting rod 341 is hinged to one end of the second connecting rod 342; the other end of the second connecting rod 342 is fixedly connected to a suction cup shaft 312; and the vertical connecting rod 343 is hinged to a horizontal connecting rod 331.

[0081] Specifically, during operation, the cam drive mechanism first drives the camshaft 311 to rotate. During the rotation of the camshaft 311, as... Figure 6 and Figure 7 As shown, the long end of the first cam 33 first abuts against the first abutting screw 332, while the short end of the second cam 34 abuts against the second abutting screw 344. During the rotation of the first cam 33, the horizontal connecting rod 331 is pressed to swing downward, thereby driving the suction cup shaft 312 and the vacuum nozzle 321 to move downward. When the suction cup shaft 312 and the vacuum nozzle 321 move downward to the bottom, the vacuum nozzle 321 adsorbs the plastic box sheet. Then, the first cam 33 continues to rotate, causing the long end of the first cam 33 to separate from the first abutting screw 332, and the horizontal connecting rod 331 returns to its original position and moves upward. When the cam shaft 311 rotates to... Figure 8When the position is shown, the short end of the first cam 33 abuts against the first abutting screw 332, and the long end of the second cam 34 abuts against the second abutting screw 344. During the rotation of the second cam 34, the vertical connecting rod 343 is pressed to swing downward. Through the action of the first connecting rod 341 and the second connecting rod 342, the suction cup shaft 312 is driven to rotate, thereby causing the vacuum nozzle 321 to swing outward at a certain angle and place the plastic box sheet on the external equipment, thus completing the feeding of the plastic box sheet. In this embodiment, by using the first cam 33, the second cam 34, the horizontal connecting rod 331, the vertical connecting rod 343, the first connecting rod 341, and the second connecting rod 342, the movement and rotation of the suction cup shaft 312 can be realized through a cam drive mechanism, which is simple in structure and saves costs.

[0082] In the vacuum feeding device described in this embodiment, the horizontal connecting rod 331 is provided with a first abutting screw 332 for abutting against the outer periphery of the first cam 33; through the above arrangement, the long end of the first cam 33 abuts against the first abutting screw 332 during the rotation of the first cam 33, thereby causing the horizontal connecting rod 331 to swing downward.

[0083] The vertical connecting rod 343 is provided with a second abutting screw 344 for abutting against the outer periphery of the second cam 34;

[0084] The second abutting screw 344 is located at the end of the vertical connecting rod 343 away from the first connecting rod 341;

[0085] The above configuration causes the long end of the second cam 34 to abut against the second abutting screw 344 during rotation, thereby causing the vertical connecting rod 343 to swing downward.

[0086] The base 1 is provided with a first reset mechanism for resetting the cross link 331;

[0087] The first reset mechanism includes a first reset screw 351 disposed on the base 1, a second reset screw 352 disposed at the other end of the cross link 331, and a first tension spring 353 disposed between the first reset screw 351 and the second reset screw 352;

[0088] The base 1 is provided with a first adjustment groove 354; the first reset screw 351 is detachably connected to the first adjustment groove 354.

[0089] With the above settings, when the long end of the first cam 33 separates from the first abutting screw 332, the cross link 331 can automatically reset, causing the suction cup shaft 312 to rise; the tension of the first tension spring 353 can be adjusted by setting the first adjustment groove 354.

[0090] The base 1 is provided with a second reset mechanism for resetting the vertical connecting rod 343;

[0091] The second reset mechanism includes a third reset screw 361 disposed on the base 1, a fourth reset screw 362 disposed at one end of the vertical connecting rod 343, and a second tension spring 363 disposed between the third reset screw 361 and the fourth reset screw 362;

[0092] The base 1 is provided with a second adjustment groove 364; the third reset screw 361 is detachably connected to the second adjustment groove 364.

[0093] With the above settings, when the long end of the second cam 34 is separated from the second abutment screw 344, the vertical connecting rod 343 can automatically reset; the tension of the second tension spring 363 can be adjusted by setting the second adjustment groove 364.

[0094] The vacuum feeding device described in this embodiment includes a moving mechanism that further includes a synchronous connecting rod 371 and a third cam 37 for driving the synchronous connecting rod 371 to swing; the third cam 37 is mounted on a camshaft 311; one end of the synchronous connecting rod 371 is rotatably connected to the machine base 1; and the other end of the synchronous connecting rod 371 is rotatably connected to the camshaft 311.

[0095] The synchronous connecting rod 371 is provided with a third abutting screw 372 for abutting against the outer periphery of the third cam 37;

[0096] The first cam 33 and the third cam 37 are respectively located at both ends of the camshaft 311. By setting the third cam 37 and the synchronous connecting rod 371, together with the first cam 33 and the cross connecting rod 331, the movement of the suction cup shaft 312 is driven, making the movement of the suction cup shaft 312 more stable and reliable.

[0097] The base 1 is provided with a third reset mechanism for resetting the synchronous link 371;

[0098] The third reset mechanism includes a fifth reset screw 381 on the base 1, a sixth reset screw 382 on the other end of the synchronous connecting rod 371, and a third tension spring 383 between the fifth reset screw 381 and the sixth reset screw 382.

[0099] The base 1 is provided with a third adjustment groove 384; the fifth reset screw 381 is detachably connected to the third adjustment groove 384.

[0100] With the above settings, when the long end of the third cam 37 separates from the third abutment screw 372, the synchronous connecting rod 371 can automatically reset, causing the suction cup shaft 312 to rise; the tension of the third tension spring 383 can be adjusted by setting the third adjustment groove 384.

[0101] The vacuum feeding device described in this embodiment includes a cam drive mechanism comprising a rotary motor 391 mounted on a base 1, a first rotary synchronous wheel 394 connected to the output end of the rotary motor 391, a second rotary synchronous wheel 392 connected to a camshaft 311, and a rotary synchronous belt 393 disposed between the first rotary synchronous wheel 394 and the second rotary synchronous wheel 392; the above arrangement enables the rotary motor 391 to drive the camshaft 311 to rotate.

[0102] The base 1 is provided with an arc-shaped groove 322; the suction cup shaft 312 moves in the arc-shaped groove 322; the above arrangement can limit the movement of the suction cup shaft 312.

[0103] The first cam 33 and the second cam 34 are located at the same end of the camshaft 311. This arrangement makes the structure more compact.
