[0002] With the rapid development of modern social economy, the importance of the packaging industry in various fields has become increasingly prominent. As a common packaging form, four-side seal bags are widely used in many industries such as food, medicine, and daily chemicals. In these industries, the quality and sealing performance of product packaging are increasingly required. Four-side seal bags have good sealing, stability and display properties, which can effectively protect the items in the bag and extend the shelf life of the product. At the same time, they can also attract consumers' attention in terms of appearance. However, to achieve high-quality four-side seal bag production, the edge sealing of the bag mouth is one of the key links.

[0003] However, the existing bag opening hot pressing edge sealing device for processing four-side sealed bags is relatively cumbersome in fixing the four-side sealed bags during use, which results in a large amount of time being required to fix the bags during processing, thereby affecting the processing efficiency of the four-side sealed bags. Utility Model Content

[0004] The purpose of the utility model is to provide a bag opening hot pressing edge sealing device for processing four-side sealed bags. By providing a clamping mechanism, the utility model solves the problem that the existing bag opening hot pressing edge sealing device for processing four-side sealed bags is relatively cumbersome in fixing the four-side sealed bags during use, resulting in a large amount of time being required to fix the bags during processing, thereby affecting the processing efficiency of the four-side sealed bags.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a bag opening hot pressing edge sealing device for processing four-side sealed bags, comprising a workbench, on which a clamping mechanism and a spacing adjustment mechanism are provided;

[0007] The top of the workbench is fixedly connected to an L-shaped support frame, the bottom of the L-shaped support frame is fixedly connected to a hydraulic cylinder, the output shaft of the hydraulic cylinder is fixedly connected to a hot pressing plate, two slide grooves are provided on the workbench, the clamping mechanism includes a clamping component 1 and a clamping component 2, the clamping component 1 includes two rectangular bottom plates arranged on the top of the workbench, the tops of the two rectangular bottom plates are fixedly connected to two sliding rods 1, and the tops of several sliding rods 1 are fixedly connected to two rectangular top plates.

[0008] Furthermore, two slides are slidably connected to the outer walls of several of the rectangular top plates, and a soft gasket 1 is fixedly connected to the bottoms of the two slides.

[0009] Furthermore, the clamping assembly 2 includes springs respectively mounted on the outer walls of several slide rods 1, the tops of several springs are respectively fixedly connected to two rectangular top plates, and the bottoms of several springs are respectively fixedly connected to two rectangular bottom plates.

[0010] Furthermore, the tops of the two skateboards are fixedly connected to pull rods, the tops of the two pull rods slide through the rectangular top plate and extend to the outside, the top side extensions of the two pull rods are fixedly connected to handles 1, and the bottoms of the two handles 1 are fixedly connected to two soft gaskets 2.

[0011] Furthermore, the spacing adjustment mechanism includes a threaded assembly and a sliding assembly, the threaded assembly includes two rectangular support plates fixedly connected to the bottom of the workbench, a bidirectional threaded rod is rotatably connected between the two rectangular support plates, and the left side of the bidirectional threaded rod rotates through the rectangular support plate on the left and extends to the outside.

[0012] Furthermore, two moving blocks are threadedly connected to the outer wall of the bidirectional threaded rod, and a second handle is fixedly connected to the left extension portion of the bidirectional threaded rod.

[0013] Furthermore, the sliding assembly includes a sliding rod 2 fixedly connected between two rectangular support plates, the sliding rod 2 slides through the two moving blocks and extends to the outside, the tops of the two moving blocks are fixedly connected with a connecting rod, and the tops of the two connecting rods respectively slide through the two sliding grooves and are respectively fixedly connected to the two rectangular bottom plates.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting a clamping mechanism, after the spacing adjustment is completed, pull handle 1, and handle 1 drives the slide plate and soft gasket 1 to move upward through the pull rod. When the slide plate moves upward, the spring will undergo elastic deformation and generate elastic force. Then, the four-side sealed bag with the required edge sealing is placed on the workbench, so that its left and right sides are aligned with the bottom of the rectangular base plate, and the side to be sealed is directly under the hot pressing plate. Then release handle 1. At this time, the slide plate will drive the soft gasket 1 to move downward under the action of the elastic force of the spring, thereby completing the fixation of the four-side sealed bag, so that it can better adapt to the irregular shape and different thickness of the bag surface, avoid local excessive pressure and damage to the bag, and ensure that the bag is firmly fixed on the workbench. In addition, the operation process is simple and clear, which helps to improve work efficiency. Especially in the batch production process, the bag placement and fixing steps can be completed quickly;

[0016] 2. By setting a spacing adjustment mechanism, before clamping the four-side sealed bag, the handle 2 can be turned according to the size of the four-side sealed bag, and the handle 2 drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, the two moving blocks will approach each other under the action of the slide rod 2. When the two moving blocks approach each other, the connecting rod running through the slide groove will drive the rectangular bottom plates to approach each other, thereby completing the adjustment of the spacing between the two clamping mechanisms, so that the device can be well adapted to four-side sealed bags of various sizes, expanding the scope of application of the device, reducing the need to replace equipment or perform complex modifications due to changes in bag size, and can accurately fix the bag opening in a suitable position, providing precise positioning for subsequent hot pressing edge sealing operations, and improving the quality and effect of edge sealing.
