[0023] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-8 shown, it is a specific embodiment of the intelligent up-down driving carton sealing machine of the application. The embodiment includes a rack 1, an upper machine core 2, a lower machine core 3 and two sets of conveying mechanisms 4. The rack 1 includes an upper rack 11 and a lower rack 12. The lower machine core 3 is located on the lower rack 12, and the upper machine core 2 is located on the upper rack 11. The upper rack 11 is movably arranged on the lower rack 12. The upper machine core 2 and the lower machine core 3 correspond in position. The two sets of conveying mechanisms 4 are opposite to each other and are respectively arranged on the two sides of the upper machine core 2 and the two sides of the lower machine core 3. A pair of clamping rods 5 is arranged at the front end of the lower rack 12. Two sets of positioning wheels 0 are arranged at the front end of the upper rack 11 and located on the two sides of the upper machine core 2. The clamping rods 5, the upper rack 11 and the positioning wheels 0 are adjusted in position by respective driving mechanisms. The driving mechanisms are signal-connected with a control module 7. The control module 7 is arranged to adjust the spacing parameters between the pair of clamping rods 5, the spacing parameters between the two sets of positioning wheels 0, the height parameters between the upper rack 11 and the lower machine core 3, and feed back signals to the driving mechanisms to control the start and stop of the driving mechanisms, so that the pair of clamping rods 5 and the two sets of positioning wheels 0 are adjusted to the required spacing, and the upper rack 11 is adjusted to the required height.

[0025] In use, the lower conveying mechanism 4 forms a platform for the smooth running of the carton on the left and right sides of the lower machine core 3. The conveying mechanisms 4 on the two sides of the upper machine core 2 are opposite to the lower conveying mechanism 4, and can stably clamp and drive the carton. The conveying mechanism 4 can be realized by using the existing conveying belt mechanism. The upper machine core 2 is installed on the upper rack 11. The upper rack 11 is lifted on the lower rack 12 by the driving mechanism, and adjusts the height distance between the upper machine core 2 and the lower machine core 3 and the height distance between the upper and lower conveying mechanisms 4. The front end of the upper rack 11 is respectively provided with two sets of positioning wheels 0, and the front end of the lower rack 12 is respectively provided with two sets of clamping rods 5, which can respectively limit and guide the carton above and below. The two sets are adjusted to approach or move away from each other on the two sides above and below by the driving mechanism. The staff can input the required adjustment parameters of the spacing of the clamping rods 5, the height parameters of the upper rack 11 and the lower machine core 3, and the spacing parameters of the positioning wheels 0 at the control module 7. The control module 7 starts each driving mechanism to complete the adjustment of the spacing and height. Compared with the original manual adjustment method, it is more labor-saving, faster and can ensure the accuracy of the adjustment position. The application can be well adapted to the rapid adjustment under the condition of changing the specifications of the carton. Overall, it reduces the downtime, reduces the difficulty of the staff's adjustment, improves the efficiency of the production and packaging, and ensures the production benefit.

[0026] As an improved specific embodiment, the driving mechanism for adjusting the clamping rod 5 includes a first driving motor a61, a first lead screw a62, and a first nut a63. The first lead screw a62 is rotatably arranged on the lower rack 12 and is driven to rotate by the first driving motor a61. The first lead screw a62 has two sections with opposite rotational directions. The first nut a63 is arranged on one side of the clamping rod 5. The two groups of first nuts a63 are arranged on the two sides of the first lead screw a62, so that the first lead screw a62 drives the two groups of first nuts a63 to move close to or away from each other when rotating, i.e., the two groups of clamping rods 5 move close to or away from each other. The first driving motor a61 is signal-connected with the control module 7.

[0027] As shown in Figure 1 , 2 , a pair of clamping rods 5 are located at the input end of the carton sealing machine. The two clamping rods are arranged in parallel to form a structure for limiting the sides of the carton. The close-to and away-from movement of the two clamping rods can be adjusted to match the width interval of the carton. The clamping rod 5 is integrally mounted on the first nut a63 to realize synchronous translation of the two clamping rods. The two first nuts a63 are sleeved on the first lead screw a62, and the two sides have different rotational directions. When the first lead screw a62 rotates, it can drive the two clamping rods 5 to move close to or away from each other. The first nut a63 is driven by the first driving motor a61. By signal connection with the control module 7, the staff can input the required interval parameter at the control module 7, and then start the first driving motor a61 to automatically adjust the interval between the two groups of clamping rods 5. Compared with the original manual adjustment method, this method is more labor-saving, faster, and can ensure the accuracy of the adjustment position. The transmission mode of the first lead screw a62 and the first nut a63 occupies a small space and is accurate and stable in transmission, which can well adapt to the rapid adjustment under the condition of changing the specifications of the carton and improve the efficiency of production and packaging.

[0028] As an improved specific embodiment, the driving mechanism for adjusting the clamping rod 5 includes a first driving motor a61, a first lead screw a62, and a first nut a63. The first lead screw a62 is rotatably arranged on the lower rack 12 and is driven to rotate by the first driving motor a61. The first lead screw a62 has two sections with opposite rotational directions. The first nut a63 is arranged on one side of the clamping rod 5. The two groups of first nuts a63 are arranged on the two sides of the first lead screw a62, so that the first lead screw a62 drives the two groups of first nuts a63 to move close to or away from each other when rotating, i.e., the two groups of clamping rods 5 move close to or away from each other. The first driving motor a61 is signal-connected with the control module 7.

[0029] As shown in Figure 2 , 6As shown, the front end of the upper rack 11 is respectively provided with left and right two groups of positioning wheels 0, which are used to limit and guide the carton on both sides of the carton with the clamping rod 5. The two positioning wheels 0 are respectively installed with a group of second nuts b63 to realize the synchronous translation of the two, and the second nuts b63 on both sides are sleeved on the second lead screw b62 and have different rotation directions. When the second lead screw b62 rotates, it can drive the two positioning wheels 0 to move closer or farther away. The second nut b63 is driven by the second drive motor b61, and the control module 7 connected with the second drive motor b61 signals. The staff can input the required adjustment interval parameter at the control module 7, and then start the second drive motor b61 to automatically adjust the interval between the two groups of positioning wheels 0. Compared with the original manual debugging mode, it is more labor-saving, faster and can ensure the accuracy of the debugging position. The transmission mode of the second lead screw b62 and the second nut b63 occupies small space and is accurate and stable in transmission, which can well adapt to the rapid debugging under the condition of changing the specifications of the carton and improve the efficiency of production and packaging.

[0030] As an improved specific embodiment, the driving mechanism further comprises a plurality of coding wheels 64, which are arranged to rotate synchronously with the first lead screw a62 and the second lead screw b62. The coding wheel 64 is uniformly provided with a plurality of detection notches 641 around the circumference, and the outer periphery of the coding wheel 64 is provided with a detection sensor 642 for detecting the rotation of the coding wheel 64. When passing through the detection notch 641, the detection sensor 642 senses to determine the number of rotations and angles of the coding wheel 64. The detection sensor 642 is signal-connected with the control module 7 for feedback of the rotation of the coding wheel 64.

[0031] As shown in the specific implementation, Figure 5 After further adopting the coding wheel 64, the rotation angle of the coding wheel 64 can match the rotation angle of the first lead screw a62, and the translation distance of the clamping rod 5 can be accurately monitored. The uniform detection notches 641 on the coding wheel 64 are evenly arranged around the circumference, and the corresponding angle can be detected once by the detection sensor 642 by dividing 360 degrees by the number of detection notches 641. When the coding wheel 64 rotates by this angle, the detection sensor 642 will correspond to the detection notch 641 once, so that the detection sensor 642 can accurately feedback the rotation angle or the number of rotations of the coding wheel 64, or rely on the detection sensor 642 to cooperate with the control module 7 to well control the rotation angle or the number of rotations of the coding wheel 64. After the first lead screw a62 rotates by the accurate angle or the number of rotations according to the required debugging parameter of the control module 7, the signal feedback of the detection sensor 642 or the coding wheel 64 is fed back to the control module 7, and the control module 7 can accurately stop the first drive motor a61 to realize accurate and stable debugging with high precision.

[0032] As shown in the specific implementation, Figure 7As shown, in specific implementation, further adopting the encoding wheel 64, the encoding wheel 64 can match the rotation angle of the second lead screw b62, and the translation distance of the positioning wheel 0 can be accurately monitored; the uniform detection notch 641 arranged on the encoding wheel 64 is divided by 360 degrees by the number of the detection notch 641, and the corresponding angle can be detected once by the detection sensor 642, so that the detection sensor 642 can accurately feed back the rotation angle or the number of turns of the encoding wheel 64, or rely on the detection sensor 642 to cooperate with the control module 7 to well control the rotation angle or the number of turns of the encoding wheel 64, so that the second lead screw b62 rotates the accurate angle or the number of turns according to the parameters required by the control module 7 to adjust, and then the signal feedback of the detection sensor 642 or the encoding wheel 64 is fed back to the control module 7, and the control module 7 can accurately stop the second drive motor b61, realize accurate and stable adjustment, and has high precision.

[0033] As an improved specific embodiment, the driving mechanism of the upper rack 11 includes a third drive motor c61, a third lead screw c62 and a third nut c63. The third lead screw c62 is rotatably arranged on the lower rack 12 and is driven to rotate by the third drive motor c61. The third nut c63 is arranged on the upper rack 11 and is sleeved on the third lead screw c62, so that the third lead screw c62 drives the third nut c63 and the upper rack 11 to rise or fall when rotating. The third drive motor c61 is signal connected with the control module 7.

[0034] As shown, Figure 2 The upper machine core 2 is installed on the upper rack 11. The two sides of the upper rack 11 are installed on the third nut c63. The two third nuts c63 are sleeved on the third lead screw c62. When the third lead screw c62 rotates, it can drive the upper rack 11 to rise or fall. The third nut c63 is driven by the third drive motor c61. By signal connection with the control module 7, the staff can input the required height parameter at the control module 7, and then start the third drive motor c61 to automatically realize the height adjustment between the upper rack 11 and the lower machine core 3 above it. Compared with the original manual adjustment method, it is more labor-saving and faster, and can ensure the accuracy of the adjustment position. The transmission mode of the third lead screw c62 and the third nut c63 occupies small space and has accurate and stable transmission, which can well adapt to the rapid adjustment under the condition of changing the specifications of the carton and improve the efficiency of production and packaging.

[0035] As an improved specific embodiment, the driving mechanism also includes a coding wheel 64, which is configured to rotate synchronously with the third screw rod c62. A number of detection notches 641 are evenly arranged on the circumference of the coding wheel 64, and a detection sensor 642 is arranged on the outer periphery of the coding wheel 64. The detection sensor 642 is used to detect the rotation of the coding wheel 64. When passing through the detection notch 641, the detection sensor 642 senses and determines the number of rotations and angles of the coding wheel 64. The detection sensor 642 is connected to the control module 7 for signal feedback on the rotation of the coding wheel 64.

[0036] like Figure 8 As shown, in the specific implementation, after further adopting the encoder wheel 64, the encoder wheel 64 can match the rotation angle of the third screw rod c62 with its own rotation angle, and can accurately monitor the lifting distance of the upper frame 11 (upper movement 2, upper transmission mechanism 4); the uniform detection notches 641 set on the encoder wheel 64 are divided by 360 degrees by the number of detection notches 641, and the corresponding angle can be detected once by the detection sensor 642, so that every time the encoder wheel 64 rotates by this angle, the detection sensor 642 will correspond to the detection notch 641 once, so that the detection sensor 642 can accurately feedback the rotation angle or number of turns of the encoder wheel 64, or rely on the detection sensor 642 to cooperate with the control module 7 to well control the rotation angle or number of turns of the encoder wheel 64, so that after the third screw rod c62 rotates the accurate angle or number of turns according to the parameters required for debugging by the control module 7, the signal of the detection sensor 642 or the encoder wheel 64 is fed back to the control module 7, and the control module 7 can accurately stop the third drive motor c61, thereby achieving accurate and stable debugging with high precision.

[0037] As an improved specific implementation method, the control module 7 is a programmable controller; the programmable controller has a touch screen or buttons for external input.

[0038] As a mature technology, programmable controllers allow manufacturers to pre-set corresponding programs. Workers can enter or call various carton specifications. The programmable controller can store the worker's selections and directly select the required parameters for the spacing between the clamping rods 5, the spacing between the positioning wheels 0, and the height of the upper frame 11 (upper movement 2, upper conveyor mechanism 4). In conjunction with various mechanical mechanisms, it can achieve good automated start and stop and control. Providing a touch screen or buttons to facilitate parameter input and selection is also more conducive to the realization of functions.

[0039] As an improved embodiment, the side of the first lead screw a62 is provided with two groups of first sensors a621 for detecting the horizontal movement limit position of the first nut a63. The two groups of first sensors a621 are respectively located at the outer limit position and the inner limit position of the horizontal movement of the first nut a63. The first sensors a621 are in signal connection with the control module 7 for feeding back signals when the first nut a63 reaches the limit positions.

[0040] As shown in Figure 3 , 4 , in the state of inputting parameters of the control module 7, the staff may input incorrect values, so that the clamp rod 5 and the first nut a63 continuously adjust and move towards the outer end or the inner end. The mechanical structure may collide, causing damage to the parts and affecting the debugging accuracy, even requiring shutdown, debugging and maintenance. Therefore, the first sensors a621 are arranged on the side of the first lead screw a62. The two groups of first sensors a621 are arranged at the limit positions of the two ends of the first lead screw a62. When the first nut a63 reaches the left and right limit positions, it will be sensed by the first sensors a621. The first sensors a621 can feed back signals to the control module 7 to stop the first driving motor a61, so as to avoid excessive movement and damage to the parts. The first sensors a621 can be preferably proximity switches or other sensor types that can sense the arrival of objects. As shown in the figure, two groups of first sensors a621 are arranged on one side of the first lead screw a62 to define the outer limit position and the inner limit position.

[0041] As an improved embodiment, the clamp rod 5 and the first nut a63 are jointly installed on a first sliding frame 53. The lower rack 12 is provided with upper and lower groups of first sliding rods 54. The first lead screw a62 is located between the two groups of first sliding rods 54. The first sliding frame 53 is arranged on the first sliding rod 54 for sliding.

[0042] As shown in Figure 1 , 2 , the left and right first sliding frames 53 are preferably arranged on the first sliding rod 54 through bearings for sliding. The first lead screw a62 located between the two groups of first sliding rods 54 can stably cooperate with the first nut a63 when rotating, driving the clamp rod 5 on the first sliding frame 53 to stably approach or move away. The overall structure is stable in translation and accurate in spacing adjustment.

[0043] As an improved embodiment, the second nut b63 and the positioning wheel 0 are jointly installed on a second sliding frame 01. The upper rack 11 is provided with upper and lower groups of second sliding rods 02. The second lead screw b62 is located between the two groups of second sliding rods 02.

[0044] As shown in Figure 2 ,7 As shown, the left and right second sliding frames 01 are preferably arranged on the second sliding rods 02 through bearings, and the second lead screws b62 between the two groups of second sliding rods 02 can stably cooperate with the second nuts b63 when rotating to drive the positioning wheels 0 on the second sliding frames 01 to stably approach or move away; the second sliding frames 01 are specifically arranged as shown below to form a plate-shaped structure for installing the positioning wheels 0, and the positioning wheels 0 are rotatably installed thereon, and the positioning wheels 0 roll against the carton with their circumferential surfaces, and the two positioning wheels 0 cooperate with the two clamping rods 5 on the sides to well limit the carton on both sides and forwardly convey it.

[0045] As an improved specific embodiment, the third lead screws c62 and the third nuts c63 are arranged on both sides of the upper frame 11, and the lower ends of the third lead screws c62 on both sides are provided with sprockets 65 and are connected and linked through chains 66.

[0046] As shown in Figure 2 , 3 , 8, a group of third driving motors c61 cooperate with the sprockets 65 and the chains 66 to drive the two groups of third lead screws c62 and the third nuts c63 on both sides to transmit power, without the need to arrange multiple driving components to drive, which well controls the cost and effectively utilizes the space below for arrangement.

[0048] As shown in Figure 4 , 5 , the coding wheel 64 is sleeved on one end of the first lead screw a62, the first driving motor a61 (motor shaft) is arranged adjacent to the first lead screw a62 in parallel, which reduces the space occupied by the first driving motor a61, and after the motor shaft of the first driving motor a61 and the end of the first lead screw a62 are provided with sprockets 65 and are connected and transmitted through chains 66, a good transmission effect is achieved, and the space can be well arranged.

[0049] As an improved specific embodiment, the clamping rod 5 includes a rod body 51 and a lower support 52, the lower end of the lower support 52 is connected to the first sliding frame 53, and the upper end is provided with the rod body 51; the rod bodies 51 on the left and right sides are arranged in parallel, and an outwardly expanding section 511 that expands and increases the distance is arranged at one end towards the front of the lower frame 12.

[0050] As shown in Figure 1As shown, when the carton enters the carton sealing machine, the spacing size of the pair of outwardly expanded sections 511 at the front end is slightly larger than the spacing between the rod bodies 51, so that the carton is better guided between the rod bodies 51 and is adapted to the width of the carton by the spacing between the rod bodies 51, so that the carton is stably aligned and travels under the driving of the up-down conveying mechanism 4 to complete the work of tape sealing by the up-down mechanism.

[0051] As an improved specific embodiment, the front end of the lower rack 12 is further provided with a roller platform 121 for supporting the material to enter, the clamping rod 5 is located between the roller platform 121 and the lower rack 12, and the space between the roller platform 121 and the lower rack 12 is further filled with an auxiliary supporting wheel 122 or an auxiliary supporting roller.

[0052] As shown in Figure 1 , the roller platform 121 can be realized by using existing technology, so that the carton can smoothly reach the clamping rod 5 and the conveying mechanism 4 under the push of the previous push mechanism or manual push, and then be limited and driven to continue to travel. The clamping rod 5 is arranged to have a gap between the roller platform 121 and the lower rack 12, and the auxiliary supporting wheel 122 or the auxiliary supporting roller is further arranged to fill the gap, so that the small-sized carton can also smoothly pass through without jolting, avoiding the occurrence of unexpected conveying.

[0055] As an improved specific embodiment, the positioning wheel 0 is arranged in two groups on the second sliding rack 01, and the two groups of positioning wheels 0 are arranged along the material conveying direction of the carton sealing machine.
