Description

Technical Field

[0001] This invention belongs to the field of automated packaging equipment, and relates to a packaging machine, specifically a bubble wrap packaging machine for express delivery. Background Technology

[0002] Bubble wrap bags are flexible packaging bags made of low-density polyethylene (LDPE) specifically designed for the express delivery industry. They are mainly used for packaging fragile, easily damaged, and delicate goods in the express delivery industry. They use a thin film to contain air and form bubbles to prevent product impact and ensure protection when the product is subjected to vibration. They also have a certain degree of heat insulation and are suitable for packaging or handling various products in the express delivery industry.

[0003] Chinese utility model patent application number 202023221671.0 discloses a bubble bag packing machine, including a machine body, a label issuing device, and a sealing structure. The machine body has an inclined guide surface along which the bubble bag slides. The label issuing device is located on the machine body, and the machine body has a label issuing port on the guide surface for the part of the product label printed by the label issuing device to extend out. The sealing structure is located below the guide surface, which receives the bubble bag containing the product and seals its opening. This bubble bag packing machine eliminates the need for manual pasting of product labels onto the bubble bags, thus achieving automatic pasting of product labels, but it cannot achieve automatic packing of the items.

[0004] Chinese utility model patent application number 202321046390.7 discloses a mobile bubble bag packing machine, relating to the technical field of bubble bag packing machines. It includes a packing machine body and a synchronization component. The packing machine body has a base at its bottom, with support columns fixed at four ends of the base. The synchronization component, used for synchronous adjustment, is located inside the base. The synchronization component includes a worm gear, a worm wheel, a rotating shaft, a drive gear, a driven gear, a screw sleeve, a screw, a positioning rod, and casters. Through the synchronization component, when the packing machine needs to be moved, simply rotating the worm gear causes the worm wheels at both ends to rotate, thereby sequentially driving the rotating shaft, drive gear, driven gear, and screw sleeve to rotate. At this time, because the positioning rod can limit the rotation direction of the screw, and the base can limit the height of the screw sleeve, the screw can push the casters, making their bottoms lower than the support columns, thus eliminating the need for separate height adjustment of each caster. This bubble bag packing machine mainly achieves movement of the packing machine by the screw driving the casters, and cannot achieve automated packing of items. Summary of the Invention

[0037] The preferred embodiments of the present invention will now be described in detail.

[0038] like Figure 1 The courier bubble bag packing machine shown includes a feeding assembly 1, a transfer assembly 2, a heat sealing assembly 3, and a track frame 4. The feeding assembly 1 is used for continuous feeding of bubble bags; the transfer assembly 2 is mounted on the track frame 4 and positioned to one side of the feeding assembly 1, receiving the bubble bags conveyed by the feeding assembly 1 and opening them. The heat sealing assembly 3 is mounted on the track frame 4 and located downstream of the transfer assembly 2, used to seal the bubble bags.

[0039] Pusher component 1 Figure 3 and Figure 4 As shown, the structure used to place and push bubble bags 1' mainly includes a support frame, a bearing mechanism 13, a bubble bag side baffle 14, and a bubble bag clamping mechanism 16.

[0040] The support frame includes a base frame and two sets of spaced-apart limiting frames 11 formed on the base frame. Specifically, the base frame is square; the limiting frames 11 are mounted on the base frame using conventional fasteners or fixed to the base frame using conventional processes such as welding, such that the two sets of limiting frames 11 are parallel to each other and perpendicular to the base frame. In this embodiment, the support frame also includes multiple support feet 12 installed at the bottom of the base frame (typically one support foot 12 is installed at each of the four corners of the base frame).

[0041] The supporting mechanism 13 is vertically and flexibly mounted on the support frame via the lifting mechanism 15. In this embodiment, the supporting mechanism 13 includes a supporting frame 131, multiple side baffle supports 133 installed at the bottom of each bubble bag side baffle 14 (two side baffle supports 133 are spaced apart on the bottom surface of each bubble bag side baffle 14), and multiple bidirectional screws 134 rotatably mounted inside the supporting frame 131 and cooperating with the side baffle supports 133 to drive them to move in opposite directions or in opposite directions (preferably there are two bidirectional screws 134, which pass through the supporting frame 131 and correspondingly pass through the side baffle supports 133; specifically, the bidirectional screws 134 are connected to the supporting frame 131 via bearings; at the same time, the bidirectional screws 134 are connected to the side baffle supports 133 via nuts of the bidirectional screws 134, i.e., the side baffle supports). The system consists of a nut on a double-acting screw 134, a second rotating handle 132 installed at the end of any double-acting screw 134, a first pulley installed on each double-acting screw 134 (i.e., there are two first pulleys, which are installed one-to-one on the double-acting screw 134 and are close to the inner wall of the support frame 131), and a first belt wound around the first pulley. When the second rotating handle 132 is manually rotated, one double-acting screw 134 can be rotated, which in turn drives the other double-acting screw 134 to rotate via the first belt. This causes the two bubble bag side baffles 14 to move towards or away from each other, thereby adjusting the distance between the two bubble bag side baffles 14 to accommodate or place bubble bags of different sizes or dimensions.

[0042] The lifting mechanism 15 is also manually operated, and its specific structure is as follows: it includes two screw fixing seats 151 mounted on the support base frame, adapter seats 152 mounted on both sides of the bearing mechanism 13 (one adapter seat 152 is mounted on each side), a ball screw 153 rotatably mounted on the screw fixing seat 151 with the nut (the nut of the ball screw 153) mounted on the adapter seat 152 (the ball screw 153 is vertically set and passes through the limiting frame 11, and its lower part is connected to the screw fixing seat 151 and its upper part is connected to the limiting frame 11 through bearings), a first rotating handle 154 mounted on the upper end of any one of the ball screws 153, transmission teeth mounted on the lower end of the ball screw 153 and located in the screw fixing seat 151, and a transmission chain mounted on the two transmission teeth (not shown in the figure). In this way, when the first rotating handle 154 is manually rotated, the two ball screws 153 rotate synchronously through the cooperation of the transmission teeth and the transmission chain, thereby realizing the synchronous lifting and lowering of the bearing mechanism 13.

[0043] There are two bubble bag side baffles 14, which are adjustablely mounted on the support mechanism 13, facing each other or back to back, as described above. In this embodiment, each bubble bag side baffle 14 includes a side plate 141, an end limiting plate 143 formed at the outer end of the side plate 141 (i.e., the end where the material is manually fed), and a lower limiting plate 142 formed at the lower side of the side plate 141 and horizontally arranged (usually formed by integral molding or welding, the same below). In this way, the bubble bags can be placed on the two spaced lower limiting plates 142 and neatly arranged by being limited by the two side plates 141.

[0044] The bubble bag clamping mechanism 16 includes a support base plate 161 mounted on the carrying mechanism 13 and located between two bubble bag side baffles 14 (the support base plate 161 is mounted on the carrying frame 131 and is horizontally arranged, parallel to the side plate 141 or the lower limiting plate 142), a slide rail 165 mounted on the support base plate 161 and parallel to the bubble bag side baffles 14 (i.e., parallel to the side plate 141 or the lower limiting plate 142), a slider 168 slidably mounted on the slide rail 165, a pusher plate 160 mounted on the slider 168, and a bubble bag side baffle. The end of plate 14 (i.e., the inner end, the end of the material discharge) and the outlet baffle strip 163 that cooperates with the push plate 160 (one outlet baffle strip 163 is installed at the end of each bubble bag side baffle plate 14, so there are two outlet baffle strips 163 that are perpendicular to the side plate body 141. The two outlet baffle strips 163 have a limiting protrusion 164 at their opposing edges. The width of the limiting protrusion 164 is smaller than the width of the end limiting plate 143 to avoid the limiting protrusion 164 being too wide, which would cause it to exert too much force on the bubble bag and affect the downstream structure (such as the material suction cup) from properly picking up the bubble bag).

[0045] In this embodiment, the bubble bag clamping mechanism 16 further includes two second pulleys 162 rotatably mounted on the support base plate 161 and located on both sides of the slide rail 165, a second belt 166 wound around the two second pulleys 162, a motor 167 mounted on the support base plate 161 and connected to any of the second pulleys 162, and a transition block 169 connected to the pusher plate 160 and mounted on the second pulleys 162. When the motor 167 is working, it can drive the movement of the transition block 169, thereby allowing the pusher plate 160 on the slider 168 to move on the slide rail 165. Since the space between the pusher plate 160 and the outlet baffle 163 is used to place bubble bags, when a bubble bag is taken (one or more), the pusher plate 160 moves toward the outlet baffle 163, which can squeeze the bubble bags to ensure their neatness and ensure the smooth discharge of bubble bags one by one.

[0046] The pusher plate 160 includes a base plate 1601 mounted on a slider 168, a support vertical plate 1602 formed on and perpendicular to the base plate 1601, a reinforcing plate 1603 formed between the support vertical plate 1602 and the base plate 1601, a pusher plate component 1604 formed on the support vertical plate 1602 and perpendicular to the slide rail 165, and a plurality of hollow holes 1605 formed on the pusher plate component 1604. This helps to ensure the contact area between the pusher plate component 1604 and the bubble bag and improve the reliability of the pusher plate 160 pushing the material. In this embodiment, the output of motor 167 is pre-set. When the downstream structure takes a bubble bag, motor 167 drives pusher plate 160 forward by the thickness of a bubble bag. More preferably, a commercially available controller is provided. When the downstream structure takes a bubble bag (sensed by a sensor, a commercially available controller is acceptable; the controller is connected to the sensor and motor 167), the sensor sends a signal to the controller, which then controls motor 167 to perform the corresponding action (this control process can use existing conventional methods and is not the inventive point of this application), so that pusher plate 160 moves forward by the corresponding dimension. In addition, it is preferable to open a clearance hole at the inner end of side plate 141 (where it connects to outlet baffle 163), and install a sensor 17 (such as a commercially available grating sensor, which can be directly connected to an alarm via a cable) at this location to sense whether there is still a bubble bag between pusher plate 160 and outlet baffle 163; when no bubble bag is detected, the alarm sounds to remind the worker to load materials.

[0047] Transfer component 2, such as Figure 2 , Figure 5 and Figure 6 As shown, the main components include a cooperating suction mechanism 21, a first suction opening mechanism 22, and a second suction opening mechanism 23. This bubble bag transfer assembly is mounted on a track frame 4. Specifically, the track frame 4 has two parallel and spaced-apart walking beams (which can be configured as one long beam (first walking beam 45, mounted on the first support profile 42) and one short beam (second walking beam 44, mounted on the second support profile 41) depending on the actual site layout). These two walking beams are equipped with a synchronous movement structure, enabling some components of the suction mechanism 21, the first suction opening mechanism 22, and the second suction opening mechanism 23 to move synchronously in a straight line. (The synchronous movement structure can utilize existing conventional drive mechanisms (such as multiple pulleys 433, transmission belts 432, transmission shafts 431, motors, etc.)) as long as it ensures the synchronous linear movement of some components of the suction mechanism 21, the first suction opening mechanism 22, and the second suction opening mechanism 23. Figure 2 and Figure 3 (As shown), this application will not elaborate on it in detail.

[0048] The suction mechanism 21 includes a first slider 211 slidably mounted on the track frame 4, a first cylinder 213 mounted on the first slider 211, a suction cup frame 214 connected to the first cylinder 213 and vertically arranged, and multiple vacuum suction cups mounted on the suction cup frame 214. Specifically, the first slider 211 is slidably mounted on the first traveling beam 45 (the first slider 211 can be connected to the belt 435, and the belt 43 can be directly or indirectly connected to the motor, so that the belt 435 can drive the first slider 211 to slide on the first traveling beam 45); the first cylinder 213 extends perpendicular to the first traveling beam 45 towards the second traveling beam 44, and is used to drive the vacuum suction cups on the suction cup frame 214 to move towards the bubble bag, thereby using the vacuum suction cups to pick up the bubble bag conveyed by the upstream structure (commercially available vacuum suction cups are acceptable).

[0049] The first suction opening mechanism 22 includes a first carrier 222 movably mounted on the track frame 4 and moving synchronously with the first slider 211, a first clamping plate 226 mounted on the first carrier 222, a first suspension 223 mounted above the first carrier 222, a plurality of first suction cups 224 mounted on the first suspension 223 and spaced apart, and a plurality of first lever cylinders 225 mounted on the first suspension 223 and cooperating with the first suction cups 224. Specifically, a second slider 221 (which can be one or more) is mounted on the bottom surface of the first carrier 222, so that the second slider 221 is slidably mounted on the first traveling beam 45 of the track frame 4, thus the first carrier 222 and the first clamping plate 226 move synchronously with the second slider 221; in order to ensure the synchronous movement of the first slider 211 and the second slider 221, the first slider 211 and the second slider 221 can be connected to the same belt to ensure the accuracy of the synchronous movement. The first suspension 223 is installed in a conventional support frame, and it is fixed and does not move with the movement of the second slider 221.

[0050] The second suction opening mechanism 23 is installed on the second traveling beam 44 of the track frame 4. It includes a first carrier plate 230 movably mounted on the track frame 4 and moving synchronously with the first carrier 222, and a second clamping plate 230' adjustablely mounted on the first carrier plate 230 and cooperating with the first clamping plate 226. (In this embodiment, the second clamping plate 230' moves synchronously with the first clamping plate 226. Therefore, one or more sliders can be installed at the bottom of the first carrier plate 230 according to conventional methods. The sliders are mounted on the second traveling beam 44, allowing the first carrier plate 230 to be slidably mounted on the second traveling beam 44 of the track frame 4.) Another transmission belt 434 can be added to the inner side of the second traveling beam 44, and the transmission belt 434 can be synchronized with the aforementioned belt 435 via a transmission shaft 431. This achieves synchronous movement of the first carrier plate 230 and the first carrier frame 222, thereby enabling the second clamping plate 230' to move synchronously with the first clamping plate 226. Alternatively, any existing conventional structure can be used, as long as it can ensure that the second clamping plate 230' and the first clamping plate 226 move synchronously, thus enabling the clamping of the bubble bag. The structure includes a second suspension 231 mounted above the first carrier plate 230 (the second suspension 231 is also mounted in a conventional support frame and fixed), an upper carrier plate 232 mounted on the second suspension 231, a mounting base plate slidably mounted on the upper carrier plate 232, multiple second suction cups mounted on the side of the mounting base plate and corresponding to the first suction cup 224, and multiple second lever cylinders 238 mounted on the mounting base plate and cooperating with the first lever cylinder 225.

[0051] In this embodiment, the second clamping plate 230' can also be adjusted and mounted on the first carrier plate 230 via the translation mechanism 239, so that the second clamping plate 230' can move toward or away from the first clamping plate 226, so that the second clamping plate 230' cooperates with the first clamping plate 226 to clamp the bubble bag or release the bubble bag. Specifically, the translation mechanism 239 includes multiple first translation slide rails 2392 (usually two) mounted on the first carrier plate 230 and perpendicular to the first clamping plate 226 or the second clamping plate 230', first translation sliders 2393 (usually an even number of first translation sliders 2393, evenly distributed on the first translation slide rails 2392) mounted on the first translation sliders 2393 and with the second clamping plate 230' mounted at their ends (there are two first translation transition plates 2391, with the second clamping plate 230' mounted at their ends), and translation cylinders 2394 mounted on the first carrier plate 230 and connected to the second clamping plate 230'. Thus, the translation cylinders 2394 can drive the second clamping plate 230' to move relative to the first clamping plate 226.

[0052] In this embodiment, the second suction opening mechanism 23 further includes multiple second translation slide rails 233 mounted on the upper plate 232 and perpendicular to the first clamping plate 226 or the second clamping plate 230', a second translation slider 234 slidably mounted on the second translation slide rails 233, a second translation adapter plate 235 mounted on the second translation slider 234, an adapter frame 236 mounted on the second translation adapter plate 235 and perpendicular to the second translation slide rails 233, and a drive mechanism 237 connected to the adapter frame 236 for driving its movement. The mounting base plate is mounted on the second translation adapter plate 235. Specifically, the drive mechanism 237 includes multiple support plates 2371 mounted on the upper plate 232, a transmission wheel 2372 mounted on each support plate 2371, a transmission belt 2373 wound around the transmission wheel 2372, a drive motor 2375 mounted on any support plate 2371 and connected to the transmission wheel 2372, and a transmission adapter block 2374 mounted on the adapter frame 236 and connected to the transmission belt 2373, thereby indirectly driving the second suction cup and the second lever cylinder 238 to move relative to the first suction cup 224 and the first lever cylinder 225 through the drive motor 2375.

[0053] In this application, the general operation process of the suction mechanism 21, the first suction opening mechanism 22, and the second suction opening mechanism 23 is as follows: the suction mechanism 21 sucks up the bubble bag, and then the first slider 211, the second slider 221, and the first carrier plate 230 move synchronously under the drive of the driving mechanism. Figure 1 The movement is from right to left, causing the second clamping plate 230' and the first clamping plate 226 to move from right to left, creating corresponding working space; the suction mechanism 21 is moved to correspond with the first lever cylinder 225 and the second lever cylinder 238; then the mounting base moves toward the suction mechanism 21, causing the first suction cup 224 and the second suction cup to respectively suck up both sides of the bubble bag, the vacuum suction cup of the suction mechanism 21 releases the bubble bag, and then the second suction cup resets (so that the mounting base moves away from the suction mechanism 21). At the same time, the first lever cylinder 225 and the second lever cylinder 238 work to clamp the mouth of the bubble bag and open the bubble bag mouth, and the person puts the item into the bubble bag; finally, the second clamping plate 230' and the first clamping plate 226 reset first (the suction mechanism 21 resets), the second clamping plate 230' moves toward the first clamping plate 226 and comes together to clamp the bubble bag with the item put in, and then moves downstream synchronously (and so on). As mentioned above, the aforementioned action process (including the subsequent heat sealing process) can be automated using a controller. This part is not the inventive point of this application, so it is not described in detail here.

[0054] The bubble bag is clamped by the second clamp 230' and the first clamp 226 and transferred to the heat sealing assembly 3 for subsequent heat sealing operations.

[0055] like Figure 7The heat sealing assembly 3 shown mainly includes a push mechanism 31 and a cutter head mechanism 32 that work together.

[0056] The pushing mechanism 31 includes multiple first support seats 311 (the first support seats 311 are usually installed on other structures, such as a conventional support frame), a first mounting profile 314 movably installed on the multiple first support seats 311, and a pushing plate 315 installed on the first mounting profile 314 and located on one side thereof. In this embodiment, the pushing mechanism 31 also includes a pushing cylinder 312 installed on the bottom surface of each first support seat 311 and a pushing adapter plate 313 connecting the pushing cylinder 312 and the first mounting profile 314, that is, the pushing cylinder 312 is connected to the first mounting profile 314 through the pushing adapter plate 313; thus, when the pushing cylinder 312 is working, it can drive the pushing plate 315 to move relative to the cutter head mechanism 32, thereby clamping or releasing the bubble bag.

[0057] In this embodiment, a first mounting groove 3151 is provided on the surface of the push plate 315 facing the first mounting profile 314. The push mechanism 31 also includes a first bolt 316 whose head is inserted into the first mounting groove 3151 and whose screw is inserted into the first mounting profile 314, and a first locking nut 317 (the first locking nut 317 is close to the corresponding surface of the push plate 315) installed on the first bolt 316 and located between the first mounting profile 314 and the push plate 315, thereby ensuring the reliability and stability of the connection between the push plate 315 and the first mounting profile 314.

[0058] The cutting head mechanism 32 includes multiple second support seats 321 (similarly, the second support seats 321 are also typically mounted on other structures, such as conventional support frames), a second mounting profile 322 mounted on the multiple second support seats 321, and an electrically heated blade 323 mounted on the second mounting profile 322 and located on one side thereof. The electrically heated blade 323 is arranged opposite to the push plate 315 and can cooperate with it. When the push cylinder 312 is working, it can drive the push plate 315 to move relative to the electrically heated blade 323, thereby clamping or releasing the bubble bag; when the bubble bag is clamped, the electrically heated blade 323 is heated by electricity to seal the bubble bag.

[0059] In this embodiment, a second mounting groove 3231 is formed on the surface of the electrically heated blade 323 facing the second mounting profile 322. The blade head mechanism 32 also includes a second bolt member 325 whose head is inserted into the second mounting groove 3231 and whose screw is inserted into the second mounting profile 322, and a second locking nut (the second locking nut is close to the surface of the second mounting profile 322) mounted on the second bolt member 325 and located between the second mounting profile 322 and the electrically heated blade 323, thereby ensuring the reliability and stability of the connection between the electrically heated blade 323 and the second mounting profile 322. The blade head mechanism 32 also includes protective plates 324 formed on both surfaces of the electrically heated blade 323 to improve the safety of using the blade head mechanism 32.
