Description

Technical Field

[0002] Sealing tape equipment for sealing, that is, tape sealing machine, is a highly automated packaging equipment, mainly used for tape sealing packaging of cartons, foam boxes and other items. Its working principle can be simply described as: the packaging box is sent to the sealing area through the conveyor mechanism, and then the tape is conveyed to the position where the box needs to be sealed through the tape supply device, and finally the tape is pasted and sealed by the sealing device.

[0003] During the operation of the above equipment, it is only necessary to push the box from one end of the conveyor belt to the other end, and the tape will automatically pack the box. The equipment has some sensitive components such as sensors, which are used to detect the position and quantity of the packaging box to ensure that the subsequent work can be carried out correctly. The sensor usually detects the conveying situation of the packaging box in real time through the principle of photoelectric detection, and feeds back the signal to the control system to realize the role of the tape in packaging the box. However, the tape sealing machine is often prone to damage. After the damage, the tape sealing machine is difficult to work. In addition, after the tape sealing machine completes the processing of the box, it is necessary to detect the tape used for sealing to detect whether the tape used for sealing is complete. Among them, the sealing tape defect detection device for sealing is usually installed at the exit conveyor belt of the sealing machine to detect the products that have been sealed. The main component is a photoelectric sensor, and it detects whether the tape is defective by emitting and receiving light. However, during the detection process, dust and impurities in the processing workshop adhere to the tape, which will affect the accuracy of the detection.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 11The present invention provides a technical solution: the conveying mechanism is one of the core components of the tape carton sealing machine, and is used to smoothly convey the box to be sealed from the input end to the carton sealing area. The mechanism usually includes components such as a conveyor belt, a driving device, and a sensor. Many components such as sensors are easily damaged after a long working time, and are easily affected by dust and impurities, and are prone to errors. Based on this, a sealing tape defect detection device for carton sealing is proposed, including a conveyor frame 1 and a support table 2 fixed to the conveyor frame 1. A rotatable tape body 3 is installed on the upper end of the support table 2. A detection unit 4 for detecting the position of the tape defect is also installed on the support table 2;

[0036] The detection part 4 includes a detection box 41 fixed to the support table 2, and a detection unit 46 for detection is installed on the detection box 41, wherein the detection unit 46 is a light sensor, which realizes the detection of tape defects, and detects the sealing tape of the carton in the form of an assembly line, which reduces the labor intensity of workers and improves work efficiency. The detection unit 46 is an existing equipment, and the detection unit 46 has a sensor, a controller and an alarm device to prompt the operator to handle;

[0037] The detection part 4 also includes an extrusion part 42 for extruding the extended tape body 3. Cleaning parts 44 are provided on both sides of the extrusion part 42. The two groups of cleaning parts 44 clean the tape body 3 and the sealing part of the box body respectively. The extrusion part 42 and the cleaning part 44 are respectively provided with a supporting component 1 43 and a supporting component 2 45 for supporting and being retractably arranged. The extrusion part 42 is used to adhere the tape body 3 to the box body. The cleaning part 44 cleans the adhered tape body 3 and the sealing part of the box body, wherein the supporting component 1 43 and the supporting component 2 45 are used to support the extrusion part 42 and the cleaning part 44 to achieve the role of limiting.

[0038] The extrusion part 42 includes an extrusion shaft 421 for extruding the tape body 3 downward, and the support component 43 includes a telescopic shaft 431, a support block 432, a shaft core 433 and a protruding edge 434. The telescopic shaft 431 is fixed to the upper end of the detection box 41, and the support block 432 is fixed to the lower end of the telescopic shaft 431. The interior of the telescopic shaft 431 has a supporting spring, the shaft core 433 transversely penetrates the support block 432, and the two are rotatably connected, the protruding edge 434 is fixed to the outer side of the shaft core 433, the shaft core 433 and the protruding edge 434 extend transversely to the interior of the detection box 41, and the extrusion shaft 421 is sleeved on the shaft core 433 and clamped with the protruding edge 434, the lower end of the extrusion shaft 421 contacts the opening of the box body, and when the box body is squeezed to the lower end of the extrusion shaft 421, the extrusion shaft 421 is rotated, and the tape body 3 is adhered to the box body to achieve the sealing effect.

[0039] The outside of the extrusion shaft 421 is provided with a mounting opening 422 extending along its axis, and a cutting blade 424 is provided inside the mounting opening 422. The upper end of the cutting blade 424 is fixed with a supporting spring 423 for support, and the supporting spring 423 is fixed in the mounting opening 422. The cutting blade 424 extends out of the mounting opening 422 to cut off the tape body 3. The cutting blade 424 can extend outward and can also be retracted inward. It should be noted that when the box body is being transmitted and sealed, the cutting blade 424 will be squeezed onto the box body during rotation, causing it to retract inward to avoid cutting off the sealed tape body 3. In addition, the tape body 3 to be sealed will also be squeezed by the cutting blade 424, and the cutting blade 424 will pierce the part of the tape body 3, but the tape is not subject to resistance and can still be squeezed and adhered to the box body by the extrusion shaft 421, thereby avoiding the breakage of the tape body 3.

[0040] An extrusion truncation shaft 47 is also fixed inside the detection box 41. When the support assembly 43 is reset, the extrusion truncation shaft 47 is extruded with the extrusion shaft 421. When the lower end of the extrusion shaft 421 has a box body, the support assembly 43 moves upward, and the extrusion truncation shaft 47 is separated from the extrusion shaft 421.

[0041] When the box body passes through the extrusion shaft 421, the extrusion shaft 421 resets downward and is squeezed by the extrusion and cutting shaft 47, so that the moving tape body 3 has resistance to movement, and the extrusion shaft 421 rotates through the cutting blade 424 to pierce the tape body 3, so that the tape body 3 is pulled and broken, completing a single sealing box.

[0042] The second support assembly 45 is identical to the first support assembly 43 and is arranged in parallel. The cleaning part 44 includes two symmetrical end plates 441. A plurality of connecting rods 442 distributed in a circumference are fixed between the two end plates 441. A clamping frame 443 is fixed on the opposite side of the two end plates 441. A rotatable support sleeve 444 is clamped between the two groups of clamping frames 443. The lower oblique parts of both sides of the support sleeve 444 are fixed with abutments 445, which are used to support on the box body. A cleaning port 446 for dust collection is opened at the lower end of the support sleeve 444. The support sleeve 444 will be supported on the box body, and the cleaning port 446 is used for dust collection to achieve cleaning.

[0043] An inner sleeve 447 is fixed between the two end plates 441, and an air inlet 1 448 is penetrated on the inner sleeve 447. The shaft core 433 of the support component 2 45 extends transversely into the inner sleeve 447, and an air inlet 2 451 is opened on the shaft core 433 of the support component 2 45, and the air inlet 2 451 cooperates with the air inlet 1 448. The air inlet 2 451 transversely penetrates the shaft core 433 and is connected with the outside world, and is used to be connected to the air suction pump body. The pump body generates suction to allow air to enter the cleaning port 446 to achieve cleaning, thereby avoiding the influence of dust as much as possible during detection, and realizing assembly line work at the same time, and continuously sealing and detecting the box body.

[0044] The outer sides of the plurality of connecting rods 442 are in contact with the supporting sleeve 444, and an internal cleaning component 5 for cleaning dust on the box body or the tape body 3 is installed between two adjacent connecting rods 442. A longitudinally slidable servo motor 6 is installed on the outer side of the detection box 41, and the output end of the servo motor 6 is fixed to the shaft core 433 of the supporting component 2 45 for driving the internal cleaning component 5 to rotate.

[0045] The inner cleaning assembly 5 includes a cleaning plate 51 and a connecting spring 52. The cleaning plate 51 is clamped between two adjacent connecting rods 442. A plurality of connecting springs 52 are fixed to the outside of each cleaning plate 51. The outside of the connecting spring 52 is fixed to the connecting rod 442. Brushes for cleaning are fixed to the outside of the cleaning plate 51. The servo motor 6 drives the brushes to rotate with the cleaning plate 51, so as to clean the upper end of the box or the tape body 3, loosen the dust, and inhale the dust.

[0046] The cleaning plate 51 is a metal sheet. When the cleaning plate 51 rotates to the lower end, it pulls the connecting spring 52 downward, so that the bristles come into contact with the box body or the tape body 3, avoiding scratches on the box body or the tape body 3 and affecting the detection again. Under the action of the gravity of the cleaning plate 51, excessive squeezing of the box body or the tape body 3 is avoided.

[0047] The working principle of the present invention is as follows: when the box is transported from the conveying rack 1, the box will come into contact with the extrusion shaft 421. In order to ensure the extrusion effect with the box, the extrusion shaft 421 will compress the telescopic shaft 431 of the support assembly 43, and the extrusion shaft 421 will also move upward. At the same time, the tape body 3 clamped by the extrusion cut-off shaft 47 and the extrusion shaft 421 will adhere to the box. The extrusion shaft 421 moving upward will separate from the extrusion cut-off shaft 47, so that the tape body 3 is only transmitted along the extrusion shaft 421 and adheres to the box under the action of pressure to achieve sealing. In addition, after the box is sealed, the box is away from the extrusion shaft 421. The extrusion shaft 421 is reset under the action of the telescopic shaft 431, so that the tape body 3 is squeezed and clamped by the cutting shaft 47 and the extrusion shaft 421, so that the movement of the tape body 3 has resistance, but the tape body 3 can continue to move. When the cutting blade 424 on the extrusion shaft 421 is squeezed by the tape body 3, the tape body 3 is punctured. In addition, when the tape body 3 is pulled with resistance, the tape body 3 is broken along the puncture point, completing the sealing of the box. The above process is repeated when the box is transported later. The box is sealed by a mechanical structure, which has a simple structure, is not easy to be damaged, realizes automatic sealing, and is easy to operate.

[0048] When the extrusion shaft 421 squeezes the box body, the extrusion shaft 421 rotates, and the cutting blade 424 also rotates. When it rotates to contact with the tape body 3, since the tape body 3 is not squeezed by the extrusion cutting shaft 47, even if the cutting blade 424 pierces the tape body 3, the tape body 3 can still adhere to the box body as the extrusion shaft 421 rotates. When the cutting blade 424 rotates to contact with the box body, it retracts into the installation opening 422 to ensure that the tape body 3 seals the box body.

[0049] The subsequent detection unit 46 detects the sealed box to check whether it is sealed by the tape body 3.

[0050] In addition, when the box is transmitted and sealed, the tape body 3 before and after the box is sealed is processed by the cleaning part 44, wherein the support sleeve 444 of the cleaning part 44 is supported on the box by the edge 445, and the cleaning port 446 faces the box. Under the action of the pump body, air is sucked to absorb the dust on the box and the tape body 3 after the box is sealed, and the cleaning is completed, so that the tape body 3 is prevented from adhering to the box and the tape body 3 after the box is sealed is easy to detect to avoid errors.

[0051] In addition, after the dust is adsorbed, the servo motor 6 drives the shaft core 433 of the supporting component 2 45 to rotate, so that the connecting rod 442 and the internal cleaning component 5 rotate, and the bristles clean the dust on the box body and the tape body 3 after the box body is sealed, and further clean it.
