Description

Technical Field

[0001] This application relates to the field of transportation equipment, and in particular to a conveying mechanism of a sealing machine. Background Art

[0002] A mask is a sanitary product, generally referring to a product worn over the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of materials such as gauze or paper.

[0003] After the existing masks are produced, they need to be bagged and transported. The masks placed in the bags need to be sealed to prevent the masks from falling out of the packaging bags. Therefore, a sealing machine is required for heat sealing. In general heat sealing methods, a conveyor belt is used, and the conveying equipment drives the packaging bags containing masks to move along the heat sealing area of the heat sealing machine, so that the heat sealing machine heat seals the bag openings of the packaging bags. However, during the conveying and heat sealing processes, due to the pressure on the packaging bags or the influence of friction, the sealing position is prone to shift, affecting the accuracy of the packaging bag sealing and the finished product rate. Summary of the Invention

[0004] In order to improve the above problems, this application provides a conveying mechanism of a sealing machine.

[0005] The conveying mechanism of a sealing machine provided by this application adopts the following technical solutions:

[0006] A conveying mechanism of a sealing machine includes a first conveying member and a second conveying member; the first conveying member and the second conveying member are sequentially arranged at intervals in the vertical direction, and a conveying space is formed therebetween. The conveying space is used for conveying packaging bags. The packaging bags are placed in the conveying space, and the conveying space is located on the sealing path of the sealing machine; the first conveying member and the second conveying member respectively abut against the bottom and top of the packaging bag, and synchronously drive the packaging bag to move along the conveying space towards the sealing path of the sealing machine.

[0007] By adopting the above technical solutions, using the conveying space formed by the interval between the first conveying member and the second conveying member, the two ends of the packaging bag are abutted. The bottom end of the first conveying member and the top end of the second conveying member have the same conveying direction, and they synchronously drive and tightly abut the packaging bag to move along the conveying space, so as to ensure that the position of the packaging bag will not shift during conveying and sealing, making the sealing position of the packaging bag accurate and improving the finished product rate.

[0008] Optionally, a calibration table is provided at the conveying opening of the conveying space.

[0009] By adopting the above technical solutions, the calibration table is used to temporarily store the packaging bags, and the placement position of the packaging bags is adjusted and calibrated through the calibration table, so as to prevent the conveying position of the packaging bags from being skewed when the packaging bags are placed into the conveying space from the conveying opening, affecting the accuracy of sealing.

[0010] Optionally, the calibration table is further provided with a pusher, and the pushing end of the pusher pushes towards the conveying space.

[0011] By adopting the above technical solution, the pusher can translate the packaging bag into the conveying space with a uniform force. Compared with manual pushing, it is easy to have uneven force, resulting in deviation of the sealing position. Therefore, pushing by the pusher can ensure accuracy. At the same time, there is no need for manual pushing into the conveying port of the conveying space, so that the rotation of the first conveying member and the second conveying member will not affect the operator, improving safety.

[0012] Optionally, a push plate is provided at the pushing end of the pusher.

[0013] By adopting the above technical solution, using the push plate can increase the pushing area of the pusher, so that when the packaging bag is subjected to the pushing force of the pusher, the push plate can be used to make the force uniform, further avoiding the deviation of the sealing position during pushing.

[0014] Optionally, a guiding groove is formed on the calibration table, and the push plate is slidably connected to the guiding groove.

[0015] By adopting the above technical solution, when the push plate moves, the push plate can only move along the guiding groove to ensure that the push plate will not deviate when pushing the packaging bag, and further ensure the accurate position of the packaging bag during pushing.

[0016] Optionally, a limiting partition is arranged on the calibration table.

[0017] By adopting the above technical solution, when the packaging bag is placed on the calibration table and abuts against the limiting partition, the placement position can be positioned, thereby further avoiding the deviation of the placement position of the packaging bag.

[0018] Optionally, scale lines are provided on the calibration table.

[0019] By adopting the above technical solution, the scale lines can be used to more clearly observe whether the placement position of the packaging bag is accurate, improving the accuracy of placing the packaging bag.

[0020] Optionally, the second conveying member is further provided with a sensor for detecting the position of the packaging bag.

[0021] By adopting the above technical solution, setting the sensor can provide intelligent induction, more accurately detect the conveying position of the packaging bag, ensure the accuracy of sealing, and improve the yield.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By using the conveying space between the first conveying member and the second conveying member to hold both ends of the packaging bag, and the bottom end of the first conveying member and the top end of the second conveying member having the same conveying direction, they are synchronously driven and pressed tightly against the packaging bag to move along the conveying space, so as to ensure that the position of the packaging bag will not shift during conveying and sealing, making the sealing position of the packaging bag accurate and improving the finished product rate;

[0024] 2. The calibration table is used to temporarily store the packaging bag, and the placement position of the packaging bag is adjusted and calibrated through the calibration table to avoid the skew of the conveying position of the packaging bag when it is put into the conveying space from the conveying port, which affects the accuracy of sealing;

[0025] 3. The pushing member can translate the packaging bag into the conveying space with a uniform force. Compared with manual pushing, it is easy to have uneven force, resulting in deviation of the sealing position. Therefore, pushing through the pushing member can ensure accuracy. At the same time, there is no need for manual pushing into the conveying port of the conveying space, so that the rotation of the first conveying member and the second conveying member will not affect the operator, improving safety;

[0026] 4. Using the push plate can increase the pushing area of the pushing member, so that when the packaging bag is subjected to the thrust of the pushing member, the push plate can be used to make the force uniform, further avoiding the deviation of the sealing position during pushing.

[0036] The following will further describe the present application in detail Figure 1 -appendix Figure 3 , with reference to the accompanying drawings.

[0037] The embodiments of the present application disclose a conveying mechanism of a sealing machine.

[0038] A conveying mechanism of a sealing machine. The main product conveyed by the present application is a packaging bag, which can contain commodities such as masks, and the packaging bag is conveyed to the sealing position of the sealing machine 8, so that the sealing machine 8 can seal the packaging bag.

[0039] Reference Figure 1As shown, the conveying mechanism includes a first conveying member 1 and a second conveying member 2; both the first conveying member 1 and the second conveying member 2 are externally connected with support frames. The first conveying member 1 and the second conveying member 2 may each include a conveyor belt and a driving device. The driving device may be two rotating rollers, a connecting frame, and a driving motor. The two rotating rollers are installed on the connecting frame, the driving motor is connected to any one of the rotating rollers, the conveyor belt is sleeved on the two rotating rollers, and the driving motor drives any one of the rotating rollers to rotate, so that the rotating roller drives the other rotating roller to rotate through the conveyor belt, thereby forming a path for conveying.

[0040] The first conveying member 1 and the second conveying member 2 are arranged at intervals in the vertical direction in sequence, and a conveying space 11 is separated. At the same time, the conveying space 11 is also a space separated in the vertical direction. The main function of the conveying space 11 is to be able to convey packaging bags. The packaging bags can be placed into the conveying space 11 from the initial ends of the first conveying member 1 and the second conveying member 2. The first conveying member 1 and the second conveying member 2 respectively abut against the bottom and top of the packaging bag. Specifically, the conveyor belts of the first conveying member 1 and the second conveying member 2 respectively abut against the bottom surface and the top surface of the packaging bag. The driving directions of the first conveying member 1 and the second conveying member 2 are opposite, so that the conveying directions of both ends of the packaging bag are the same and synchronous. Subsequently, the driving device drives the conveyor belt to rotate, so as to synchronously drive the packaging bag to move along the conveying space 11 towards the sealing path of the sealing machine 8.

[0041] By using the conveying space 11 separated by the first conveying member 1 and the second conveying member 2 to abut against both ends of the packaging bag, and the bottom end of the first conveying member 1 and the top end of the second conveying member 2 have the same conveying direction, synchronously driving and tightly abutting the packaging bag to move along the conveying space 11, so as to ensure that the position of the packaging bag will not shift during conveying and sealing, making the sealing position of the packaging bag accurate and improving the yield.

[0042] In some embodiments, a calibration table 3 is provided at the conveying ports of the first conveying member 1 and the second conveying member 2. The calibration table 3 is used to temporarily store the packaging bags, and adjust and calibrate the placement positions of the packaging bags through the calibration table 3, so as to avoid the conveying position of the packaging bags being skewed when the packaging bags are placed into the conveying space 11 from the conveying ports, which affects the accuracy of sealing.

[0043] Furthermore, referring to Figure 2 As shown, the calibration table 3 is further provided with a pushing member 4. The pushing direction of the pushing member 4 is to push towards the conveying space 11. The pushing member 4 can adopt driving elements such as air cylinders, electric push rods, electric cylinders, and oil cylinders, and the driving directions are all towards the conveying space 11. So that when the packaging bag is placed on the calibration table 3, after fine-tuning and calibration on the calibration table 3, the pushing end of the pushing member 4 pushes the packaging bag towards the conveying space 11, thereby pushing the packaging bag into the conveying port and entering the conveying space 11 for conveying by the first conveying member 1 and the second conveying member 2.

[0044] Setting the pusher 4 can improve the accuracy and safety of pushing. The pusher 4 can translate the packaging bag into the conveying space 11 with a uniform force. Compared with manual pushing, it is easy to have uneven force, resulting in deviation of the sealing position. Therefore, pushing through the pusher 4 can ensure accuracy. At the same time, there is no need for manual pushing into the conveying port of the conveying space 11, so that the rotational action of the first conveyor 1 and the second conveyor 2 will not affect the operator, improving safety.

[0045] Furthermore, referring to Figure 2 As shown, a push plate 5 is provided at the pushing end of the pusher 4. Using the push plate 5 can increase the pushing area of the pusher 4, so that when the packaging bag is subjected to the pushing force of the pusher 4, the push plate 5 can be used to make the force uniform, further avoiding the deviation of the sealing position during pushing.

[0046] Still further, referring to Figure 3 As shown, a guiding groove 31 is formed on the calibration table 3. The push plate 5 is slidably connected to the guiding groove 31. Specifically, a pushing protrusion is provided at the bottom of the push plate 5, and the pushing protrusion is located in the guiding groove 31, so that when the push plate 5 moves, it is limited in the guiding groove 31 through the pushing protrusion, so that the push plate 5 can only move along the guiding groove 31, ensuring that the push plate 5 will not deviate when pushing the packaging bag, and further ensuring the accuracy of the position of the packaging bag during pushing.

[0047] In some embodiments, a limiting partition 6 is provided on the calibration table 3. Multiple limiting partitions 6 can be provided, which are respectively located on the calibration table 3 and enclose a space for storing the packaging bag. When the packaging bag is placed on the calibration table 3 and abuts against one of the limiting partitions 6, the placement position can be positioned, thereby further avoiding the deviation of the placement position of the packaging bag.

[0048] Among them, when multiple limiting partitions 6 are provided, the size of the enclosed space is exactly the same as the outer size of the packaging bag, so that when the packaging bag is placed in this space, it just fits into the space, and the edge of the packaging bag just contacts the limiting partition 6, so that the placement position of the packaging bag is accurate. At the same time, no fine adjustment is required, and the accurate placement position of the packaging bag can be ensured without fine adjustment, so as to improve the sealing efficiency.

[0049] Among them, one of the limiting partitions 6 can also be slidably connected to the calibration table 3. The calibration table 3 is also provided with a limiting groove 32. The limiting partition 6 is slidably connected to the calibration table 3 through the limiting groove 32. By using the limiting groove 32, the limiting partition 6 can move along the calibration table 3 to adjust the size of the enclosed space to adapt to different sizes of packaging bags. For example, the packaging bags for children's masks and adult masks have different sizes, and the position of the limiting partition 6 can be adjusted through the limiting groove 32 to adapt to different sizes.

[0050] In some embodiments, referring to Figure 3As shown, the calibration table 3 is provided with scale lines. By using the scale lines, it is possible to more clearly observe whether the placement position of the packaging bag is accurate. For example, if the length of the packaging bag is 10 cm, and the scale line at the 11 cm position is covered, it means that the position of the packaging bag has shifted, enabling the worker to make fine adjustments according to the scale line to align the packaging bag with the scale line at the 10 cm position. The use of scale lines can improve the accuracy of placing the packaging bag.

[0051] Among them, if the limit groove 32 is provided, when the limit partition 6 is slidably connected to the limit groove 32, the scale lines can also be used to observe the sliding position of the limit partition 6, improving the accuracy of the movement of the limit partition 6.

[0052] In some embodiments, refer to Figure 3 As shown, sensors 7 are provided on each of the second conveying members 2 for detecting the position of the packaging bag. Specifically, they can be installed on the connecting frame of the second conveying member 2 corresponding to the initial end of the sealing path of the sealing machine 8. The sensors 7 can be photoelectric sensors 7. When the photoelectric sensors 7 sense that the packaging bag moves along the first conveying member 1 and the second conveying member 2 to the sealing machine 8, they send an electrical signal to the sealing machine 8, and the sealing machine 8 can then be activated to heat-seal the bag mouth of the packaging bag.

[0053] Setting the sensors 7 can provide intelligent sensing, more accurately detect the conveying position of the packaging bag, ensure the accuracy of sealing, and improve the yield.

[0054] In some embodiments, when secondary sealing is required, an additional conveyor belt can be added at the ends of the first conveying member 1 and the second conveying member 2 to convey the sealed packaging bag back to the calibration table 3 in the reverse direction. The worker at the calibration table 3 can flip the packaging bag to change the sealing position and seal the other bag mouth of the packaging bag to achieve the convenience of secondary sealing.

[0055] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
