[0002] In the existing packaging machinery field, the horizontal bagging packaging machine, as an efficient and automated packaging device, is widely used in multiple industries such as food, medicine, and chemical industry. Such packaging machines are usually equipped with a heat sealing device for sealing the packaging bag after the material filling is completed.

[0003] Currently, Chinese Patent No. CN212767103U discloses a horizontal bagging packaging machine, which includes a bag taking device, a bag sucking device, a loading device, a sealing device, and a bag feeding device running through the entire packaging machine. The bag taking device includes a bag placing mechanism and a bag grasping mechanism. The bag placing mechanism is used for limiting and placing the packaging bag, and the bag grasping mechanism is used for grasping the packaging bag and moving it to a specified position; the bag sucking device is used for separating the bag mouth of the packaging bag, the loading device is used for loading materials into the packaging bag, and the sealing device is used for closing the bag mouth. This application improves the efficiency of separating the bag mouth of the packaging bag, facilitates subsequent bagging, and improves the applicability of the bag sucking device to different types of packaging bags;

[0004] However, in the prior art, for packaging machines similar to the above, in the actual application process, due to the diversity of the packaging bag materials, the performance of bags made of different materials varies after going through the heat sealing process. Especially for bags made of certain specific materials, after the heat sealing is completed, during the natural cooling process, problems such as bending and wrinkling often occur at the sealing part, which not only affects the aesthetics of the packaging but may also have an adverse impact on the sealing performance of the packaging.

[0005] In response to the above problems, although there have been some solutions in the industry to try to alleviate the uneven sealing phenomenon by optimizing the heat sealing parameters or improving the heat sealing structure, the effects are limited, and it is often impossible to take into account all types of packaging bags. Especially when pursuing high - efficiency production, how to ensure the sealing quality has become an urgent technical problem to be solved. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a cold sealing device for a horizontal bagging packaging machine, and its advantage lies in being able to avoid the situation of wrinkles at the bag mouth of the packaging bag after natural cooling of the heat sealing.

At the same time, the bag receiving mechanism is located on both sides of the packaging bag. At this time, the bag receiving mechanism clamps the packaging bag. Then, the conveying mechanism drives the material taking mounting plate to move below the sealing mechanism. At this time, the sealing mechanism works and cold-seals the packaging bag in a cold-sealing manner to avoid the situation of wrinkles at the bag mouth of the packaging bag after natural cooling of heat sealing.

[0014] In a preferred embodiment: a mounting plate is fixedly connected to the sealing mounting frame, and the second cylinder is fixedly arranged on the mounting plate.

[0020] In a preferred embodiment: the bag receiving mechanism includes a first cylinder installed on the material taking mounting plate, a first connecting plate installed on the piston rod of the first cylinder, and a plurality of clamping members installed on the first connecting plate.

[0021] By adopting the above technical solution, the first cylinder serves as a power source to drive the clamping member to operate, thereby clamping the packaging bag.

[0022] In a preferred embodiment: The clamping member includes a bag-pressing slider and a bag-pressing urethane rubber fixed on the bag-pressing slider.

[0023] By adopting the above technical solution, the bag-pressing urethane rubber is made of an elastic material to prevent the packaging bag from being damaged.

[0024] In a preferred embodiment: One side of the first connecting plate is fixedly connected with a first limiting rod, and the first limiting seat is fixedly connected to the material-taking mounting plate, and one end of the first limiting rod penetrates through the first limiting rod.

[0025] By adopting the above technical solution, the first limiting rod slides on the first limiting seat to provide sliding support for the linear motion of the first connecting plate.

[0026] In a preferred embodiment: Two proximity switches are also installed on the top plate.

[0027] By adopting the above technical solution, the proximity switches are used to detect the position of the material-taking mounting plate, and thus can send signals to the motor of the conveying mechanism to indicate whether to stop, work forward or reverse.

[0037] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure.

[0038] In the description of the present disclosure, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships in which the disclosed product is usually placed during use, or the orientation or positional relationships commonly understood by those skilled in the art.

[0039] A cold sealing device for a horizontal bag feeding type packaging machine, as Figures 1-4 shown, includes:

[0040] A frame 1 for bottom support, serving as the foundation for the operation of the overall mechanism;

[0041] A conveying mechanism 2 installed on the frame 1, and a material taking mounting plate 21 is installed on the conveying mechanism 2 for conveying packaging bags;

[0042] A bag receiving mechanism 3, with two groups in total, installed on the material taking mounting plate 21 for clamping packaging bags;

[0043] A sealing mechanism 4, with two groups in total, installed on the material taking mounting plate 21 for cold sealing packaging bags;

[0044] Among them, the sealing mechanism 4 includes a sealing mounting frame 41 fixed on the top plate 11, a second cylinder 43 installed on the sealing mounting frame 41, and a cold pressing plate 44 fixed on the piston rod of the second cylinder 43;

[0045] During operation, the conveying mechanism 2 first drives the material-taking mounting plate 21 to move below the packaging bag. At the same time, the bag-receiving mechanism 3 is located on both sides of the packaging bag. At this time, the bag-receiving mechanism 3 clamps the packaging bag. Then, the conveying mechanism 2 drives the material-taking mounting plate 21 to move below the sealing mechanism 4. At this time, the sealing mechanism 4 works and cold-seals the packaging bag in a cold-sealing manner to avoid the situation of wrinkles at the bag mouth of the packaging bag after natural cooling of heat sealing.

[0046] In one specific embodiment, as Figure 1 shown, the frame 1 is used for bottom support to lay the foundation for the operation of the overall mechanism. A material-receiving chute 12 is installed at the bottom of the top plate 11. A material-discharging hole 22 is formed on the material-taking mounting plate 21. The material-receiving chute 12 is located below the material-discharging hole 22. The material-discharging hole 22 enables the cold-sealed packaging bag to fall, and the material-receiving chute 12 is used for guiding.

[0047] It should be noted that the material-receiving chute 12 is only used to guide the sliding direction of the packaging bag. In actual application, manual or machine transfer methods should be adopted to transfer the sealed packaging bag.

[0048] In one specific embodiment, as Figure 2 shown, two proximity switches 23 are also installed on the top plate 11. The proximity switches 23 are used to detect the position of the material-taking mounting plate 21, and thus can send signals of whether to stop, work forward or backward to the motor of the conveying mechanism 2 to achieve automatic operation.

[0049] In one specific embodiment, as Figure 3 shown, the bag-receiving mechanism 3 includes a first cylinder 31 installed on the material-taking mounting plate 21, a first connecting plate 32 installed on the piston rod of the first cylinder 31, and a plurality of clamping members installed on the first connecting plate 32. The first cylinder 31 serves as a power source to drive the clamping members to work, thereby clamping the packaging bag.

[0050] It is worth mentioning that the clamping members can slide horizontally on the first connecting plate 32, thereby adjusting the distance between the plurality of first connecting plates 32 and adjusting the position of the clamping members according to actual needs.

[0051] Moreover, in order to prevent the clamping members from damaging the packaging bag, the clamping members adopt pressing bag sliders 35 and pressing bag urethane rubbers 36 fixed on the pressing bag sliders 35. The pressing bag urethane rubbers 36 are made of elastic materials to prevent the packaging bag from being damaged;

[0052] Furthermore, in order to improve the working stability, one side of the first connecting plate 32 is fixedly connected with a first limiting rod 34, and a first limiting seat 33 is fixedly connected to the material-taking mounting plate 21. One end of the first limiting rod 34 penetrates through the first limiting rod 34.

[0053] In one specific embodiment, asFigure 4 As shown in the figure, the sealing mechanism 4 includes a sealing mounting frame 41 fixed on the top plate 11, a second cylinder 43 mounted on the sealing mounting frame 41, and a cold pressing plate 44 fixed on the piston rod of the second cylinder 43. A mounting plate 42 is fixedly connected to the sealing mounting frame 41, and the second cylinder 43 is fixedly arranged on the mounting plate 42. The mounting plate 42 serves as the basis for mounting the second cylinder 43. One side of the cold pressing plate 44 is fixedly connected with a second limiting rod 45, and a second limiting seat 46 is fixedly connected to the mounting plate 42. One end of the second limiting rod 45 penetrates through the second limiting seat 46 to improve the sealing stability.

[0054] The beneficial effects of the present utility model are as follows:

[0055] The cold sealing device is designed as an independent external type, and users can choose whether to install and use it according to actual needs, avoiding waste of resources and enhancing the flexibility of the equipment. For users with different production requirements, this design provides more choices and customization space.

[0056] By adopting the cold sealing technology, the device can effectively solve the problem of uneven sealing of the packaging bag after heat sealing. Especially for some materials that are easy to bend and wrinkle, the cold sealing and flattening process significantly improves the flatness and aesthetics of the packaging, and at the same time ensures the sealing performance of the packaging.

[0057] The device integrates a conveying mechanism 2, a bag receiving mechanism 3 and a sealing mechanism 4, and can realize the whole process from bag taking, clamping, conveying to cold sealing.

[0058] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
