Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to an automatic heat sealing device with bilateral coordinated action. Background Technology

[0002] As the core equipment for tissue packaging, the tissue bag sealing device directly affects the product's shelf life and hygiene safety, and must simultaneously meet the requirements of sealing performance and shape adaptability. However, most current devices are limited by cost considerations and insufficient technological investment, and generally suffer from simple structures and limited sealing functions. Specifically, the rigid and flat sealing components of existing devices cannot adapt to the diverse shapes of tissue packaging bags, such as irregularly shaped bags and bags with folded edges. When faced with curved corners and multi-layered folded areas, it is easy for some areas to be unsealed or for excessive pressure to cause the packaging bag to deform or break, which not only damages the packaging's aesthetics but also increases the risk of tissues scattering during transportation. Insufficient sealing performance and shape adaptability not only cause tissues to become damp and breed bacteria, affecting safety, but also force companies to limit bag design or increase packaging costs.

[0003] Therefore, developing high-sealing sealing devices with intelligent control and shape adaptation capabilities has become an urgent need for the industry to improve quality and promote innovation. Utility Model Content

[0052] An automatic heat-sealing device with bilateral coordinated action includes: a support 1, a pair of sealing mechanisms disposed on the upper and lower sides of the support 1, and a pair of telescopic shaping mechanisms disposed on the left and right sides of the support 1; the two telescopic shaping mechanisms are horizontally and symmetrically arranged, with a distance between them, and are used to limit the positioning of the packaging bag to be sealed; the two sealing mechanisms are vertically and symmetrically arranged, and the two telescopic shaping mechanisms are located between the two sealing mechanisms; the lower end of the first sealing mechanism located on the upper side of the support 1 is connected to a first heating sealing end, and the upper end of the second sealing mechanism located on the lower side of the support 1 is connected to a second heating sealing end corresponding to the first heating sealing end; the first sealing mechanism controls the first heating sealing end to move vertically, and the second sealing mechanism controls the second heating sealing end to move vertically; under the action of the first sealing mechanism and the second sealing mechanism, the first heating sealing end and the second heating sealing end are brought closer to or moved away from each other, and the area between the first heating sealing end and the second heating sealing end is the placement area of ​​the packaging bag to be sealed.

[0053] In one embodiment of this utility model, two telescopic shaping mechanisms are located on the left and right sides of the support 1, respectively corresponding to the middle of the support 1. Each telescopic shaping mechanism includes: a fixed plate 2, a horizontal cylinder 3, a first top plate 4, and a second top plate 5. The fixed plate 2 is horizontally installed on one side of the support 1 along the X-axis direction. The horizontal cylinder 3 is horizontally oriented towards the center of the support 1 and parallel to the X-axis direction on the fixed plate 2. The first top plate 4 is disposed on the front surface of the fixed end of the horizontal cylinder 3 along the X-axis direction. The second top plate 5 is disposed at the bottom of the fixed end of the horizontal cylinder 3 along the X-axis direction and located on one side of the first top plate 4. The horizontal cylinder 3 drives the first top plate 4 and the second top plate 5 along the X-axis direction. To accommodate the conical grooves on both sides of the packaging bag, the first top plate 4 is conical at the end facing the center of the support 1, and the second top plate 5 is L-shaped. In actual operation, the two telescopic shaping mechanisms, under the control of their horizontal cylinders 3, move closer to the packaging bag to be sealed in the placement area. At this time, the packaging bag to be sealed is filled with paper towels. The two first top plates 4 press against the grooves on both sides of the packaging bag, and the two second top plates 5 are set at the middle position of the cone. That is, the two first top plates 4 press against the bottom of the grooves on both sides of the packaging bag at the rear position, thereby matching and limiting the irregular structure of the packaging bag, and then the corresponding sealing operation can be performed.

[0054] In one embodiment of this utility model, each sealing mechanism performing the sealing operation includes: a vertical cylinder 6, a mounting base 7, a base plate 8, and a limiting slider 9; the vertical cylinder 6 is vertically disposed on the top or bottom of the bracket 1 along the Y-axis direction, with its fixed end connected to the bracket 1 via the mounting base 7, and its piston end facing the center of the bracket 1; the base plate 8 is horizontally connected to the piston end of the vertical cylinder 6 along the X-axis direction, and the limiting slider 9 is disposed on the base plate 8 at positions corresponding to the left and right sides of the bracket 1; the vertical cylinder 6 can control the base plate 8. The second heating sealing end or the first heating sealing end is installed along the length of the base plate 8 on the side of the base plate 8 facing the center of the support 1. After the above-mentioned telescopic shaping mechanism limits the packaging bag, the vertical cylinders 6 of the two sealing mechanisms move toward the packaging bag to be sealed. At this time, the two base plates 8 drive the second heating sealing end and the first heating sealing end to move toward the packaging bag to be sealed, and squeeze the sealing part of the packaging bag until the second heating sealing end and the first heating sealing end come into contact for a period of time, and the corresponding sealing action is completed.

[0055] Specifically, such as Figure 1 As shown, to improve stability, each sealing mechanism has two vertically arranged cylinders 6 arranged side by side;

[0056] Specifically, to improve stability, there are two limiting sliders 9, which are respectively set at both ends of the base plate 8 and correspond to the positions of the brackets 1 on the left and right sides of the base plate 8. To further ensure the accuracy and stability of the device during operation, limiting slide rails 22 are respectively set on the left and right sides of the brackets 1, corresponding to the positions of the two limiting sliders 9, and are vertically arranged along the Y-axis. The two first limiting sliders 9 of the first sealing mechanism are slidably connected to the two limiting slide rails 22, and the two second limiting sliders 9 of the second sealing mechanism are slidably connected to the two limiting slide rails 22. When the aforementioned vertical cylinder 6 is activated, the limiting sliders 9 will slide along the limiting slide rails 22, thereby ensuring motion stability and motion control accuracy, and further improving the sealing precision.

[0057] As one embodiment of this utility model, the first heating sealing end includes: a first horizontal pressure plate 10, a first serrated pressure plate 11, a first oblique tooth pressure plate 12, and a pair of first irregularly shaped pressure plates 13; the first horizontal pressure plate 10 is horizontally connected to the lower surface of the first base plate 8 of the first sealing mechanism along the X-axis direction, and the first horizontal pressure plate 10 is set perpendicular to the base plate 8 in the horizontal direction, with the side of the first horizontal pressure plate 10 facing the center of the support 1 being a horizontal plane; the first serrated pressure plate 11 is parallel to the first horizontal pressure plate 10 and connected to the lower surface of the first base plate 8, and is located behind the first horizontal pressure plate 10, and the first serrated pressure plate 11 and the first water A gap is provided between the flat pressure plates 10, and a number of rounded serrations 14 are arranged along the length of the first serrated pressure plate 11 on the side facing the center of the bracket 1. The serrations are designed to increase the heat dissipation effect of the pressure plate. The first oblique serrated pressure plate 12 is parallel to the first horizontal pressure plate 10 and connected to the lower surface of the first base plate 8, close to the first serrated pressure plate 11. The first oblique serrated pressure plate 12 is located to the right of the first serrated pressure plate 11 relative to the first horizontal pressure plate 10. There is a distance between the first oblique serrated pressure plate 12 and the first serrated pressure plate 11. The first oblique serrated pressure plate 12 is arranged along the length of the first oblique serrated pressure plate 11 on the side facing the center of the bracket 1. The plate 12 has several oblique teeth arranged along its length toward the center of the bracket 1. The oblique teeth and the subsequent space spacing are designed to dissipate heat from the first sealing heating end. Two first irregularly shaped pressure plates 13 are arranged parallel to the first horizontal pressure plate 10, and are symmetrically positioned on the front and rear sides of the first obliquely shaped pressure plate 12. The upper ends of the two first irregularly shaped pressure plates 13 are connected as a single unit, and this connection point is also movably connected to the lower surface of the first base plate 8. Each of the two first irregularly shaped pressure plates 13 has an L-shaped groove 15 on its side facing the center of the bracket 1. The first… A horizontal pressure plate 10, a first sawtooth pressure plate 11, a first oblique tooth pressure plate 12, and a pair of first irregular pressure plates 13 are all connected to an external heating end near the device. The external heating end is used to heat the first horizontal pressure plate (10), the first sawtooth pressure plate (11), the first oblique tooth pressure plate (12), and the pair of first irregular pressure plates (13). Since the focus of this application is on the structure of the sealing mechanism, how to heat the pressure plates is not the focus of this application. Therefore, the connection between the wiring harness of the external heating end and the pressure plates will not be described in detail. It is sufficient to achieve a connection without interference. The relevant wiring harness will not be shown in the attached drawings.

[0058] Specifically, in one optional embodiment, in order to achieve effective sealing and complete a flexible sealing action with a buffer function, the upper left and right sides of the first oblique tooth pressure plate 12 are respectively connected to the lower surface of the first base plate 8 by two connecting rods 20 that avoid the first irregular pressure plate 13; the upper ends of the two first irregular pressure plates 13 are connected to each other and are arranged to avoid the connecting rods 20, and there is a distance between the upper ends of the two first irregular pressure plates 13 and the lower surface of the base plate 8; a buffer cylinder 2 is vertically arranged on the upper surface of the first base plate 8 corresponding to the position of the first irregular pressure plate 13. 1. The piston end of the buffer cylinder 21 extends vertically downward through the first base plate 8 and connects to the upper ends of the two first irregularly shaped pressure plates 13. When the first heating sealing end comes into contact with the second heating sealing end, under the action of the two vertical cylinders 6, the second heating sealing end will also squeeze the first irregularly shaped pressure plate 13 on the first heating sealing end. At this time, under the action of the buffer cylinder 21, the first irregularly shaped pressure plate 13 slowly moves upward, and the packaging bag between the first heating sealing end and the second heating sealing end will slowly come into contact with the oblique teeth on the first oblique tooth pressure plate 12, achieving a better sealing effect.

[0059] As one embodiment of this utility model, the second heating sealing end includes: a second horizontal pressure plate 16, a third horizontal pressure plate 17, and a fourth horizontal pressure plate 18 stacked together with basically the same structural dimensions; the second horizontal pressure plate 16 is parallel to the first horizontal pressure plate 10 and connected to the upper surface of the second base plate 8 of the second sealing mechanism, corresponding to the position of the first horizontal pressure plate 10, and a horizontal heating strip 19 is provided on the side of the second horizontal pressure plate 16 facing the center of the bracket 1; the third horizontal pressure plate 17 is parallel to the first horizontal pressure plate 10 and connected to the upper surface of the second base plate 8, corresponding to the position of the first serrated pressure plate 11, and two horizontal heating strips 19 are installed on the side of the third horizontal pressure plate 17 facing the center of the bracket 1; the fourth horizontal pressure plate 18 is parallel to the first horizontal pressure plate 10 and connected to the upper surface of the second base plate 8 of the second sealing mechanism, corresponding to the position of the first oblique tooth pressure plate 12 and a pair of first irregular pressure plates 13, and a horizontal heating strip 19 is provided on the side of the fourth horizontal pressure plate 18 facing the center of the bracket 1; the second heating sealing end mainly provides a stable heat sealing function.

[0060] As one embodiment of this utility model, the operating principle of this device is as follows:

[0061] When in use, this device is integrated into the conveyor line for tissue packaging bags. After the packaging bag is filled with tissues, the packaging bag is sealed as follows:

[0062] When the packaging bag containing tissues is transferred between the two telescopic shaping mechanisms, the two telescopic shaping mechanisms, under the control of their respective horizontal cylinders 3, move closer to the sides of the packaging bag containing tissues in the placement area. At this time, under the translation action, the two first top plates 4 slowly press against the grooves on both sides of the packaging bag, and the two second top plates 5 cooperate with the two first top plates 4 to press against the bottom of the grooves on both sides of the packaging bag at the rear position, thereby matching and limiting the irregular structure of the packaging bag.

[0063] After the limit is reached, the vertical cylinders 6 of the two sealing mechanisms move toward the packaging bag. At this time, the two base plates 8 drive the second heating sealing end and the first heating sealing end to approach the packaging bag to be sealed, and squeeze the sealing area of ​​the packaging bag until the second heating sealing end and the first heating sealing end come into contact for a period of time, and the corresponding sealing action is completed. During the sealing process, when the first heating sealing end and the second heating sealing end come into contact, the first heating sealing end performs high-temperature heat sealing on the packaging bag, and the second heating sealing end performs low-temperature heat sealing on the packaging bag, so as to achieve a better sealing effect.

[0064] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
