Description

Technical Field

[0001] This utility model relates to the field of pre-made bag packaging machine technology, specifically a sealing mechanism for a horizontal pre-made bag packaging machine. Background Technology

[0002] A pre-made bag packaging machine is a packaging device used to automatically fill, seal, and shape pre-made bags. It is widely used in the food, pharmaceutical, daily necessities, and chemical industries, improving packaging efficiency, ensuring packaging quality, and reducing labor costs.

[0003] However, the sealing mechanism used in existing horizontal pre-made bag packaging machines has the following disadvantages:

[0004] (1) The sealing mechanism of the existing horizontal pre-made bag packaging machine has a weak installation buffer function. The existing sealing packaging machine is not convenient to disassemble and replace the sealing contact structure. Due to the long-term use of the sealing structure, the surface of the structure is worn and damaged, and the pressure cannot be transmitted evenly, resulting in local air leakage in the sealing area.

[0005] (2) The sealing mechanism of the existing horizontal pre-made bag packaging machine has a weak sealing stability function. The sealing structure of the existing technology generally adopts a rigid pressure plate. The rigid pressure plate is difficult to adapt to packaging bags of different thicknesses or materials, which can easily cause sealing wrinkles or damage. Utility Model Content

[0006] The purpose of this invention is to provide a sealing mechanism for a horizontal pre-made bag packaging machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sealing mechanism for a horizontal pre-made bag packaging machine, comprising: an installation buffer assembly and an adaptation sealing assembly. The installation buffer assembly consists of a base, a fixing block, a connecting plate, bolts, a pneumatic rod, a spring, a fixing plate, a slide rail, a slider, a square plate, and a threaded rod. A fixing block is installed on the side of the base, a connecting plate is provided on the side of the fixing block, a bolt is installed on one side of the connecting plate, a pneumatic rod is provided at the top of the connecting plate, a spring is provided on the surface of the pneumatic rod, a fixing plate is installed at the top of the pneumatic rod, a slide rail is provided at the top of the fixing plate, a slider is provided on the inner wall of the slide rail, a square plate is provided on one side of the slide rail, and a threaded rod is installed on one side of the square plate.

[0008] The adaptive sealing assembly consists of a connecting block, a magnetic strip, a medium-density layer, a sponge layer, and a high-density layer. The connecting block is installed at the top of the slider, and a magnetic strip is installed between the connecting block and the slider. A medium-density layer is provided at the top of the connecting block, a sponge layer is provided above the medium-density layer, and a high-density layer is fixedly connected above the sponge layer.

[0009] Optionally, there are two slide rails, which are symmetrically distributed to ensure stable fixation of the sealing assembly.

[0010] Optionally, there are four pneumatic rods, which are symmetrically distributed, and bolts are used to connect to the connecting plate and the fixing block.

[0011] Optionally, the side of the fixing block is provided with a connecting groove, and the bolt passes through the connecting plate and connects with the fixing block. The bolt and the connecting plate are connected to the fixing block to fix the connecting plate to the side of the device.

[0012] Optionally, a fixing groove is provided on one side of the slider, and the threaded rod passes through the square plate and connects to the slider. The threaded rod is used to fix the slider, and the square plate is used to limit the movement of one side of the slide rail.

[0013] Optionally, the pore size of the sponge layer is 0.5-2mm, and the medium-density layer and high-density layer are made of polyurethane. The pore size of the sponge layer is 0.5-2mm. This pore size range can ensure that the air inside the sponge layer can quickly escape through the honeycomb-shaped through holes during the sealing process.

[0014] Compared with this device, the beneficial effects of this utility model are:

[0015] 1. The sealing mechanism of this horizontal pre-made bag packaging machine, through the arrangement of a base, fixed block, connecting plate, bolts, pneumatic rod, spring, fixed plate, slide rail, slider, square plate, and threaded rod, allows for operation. The base is connected to the fixed block, and the connecting plate is securely fixed to one side of the fixed block by rotating the bolts. Then, the slider is inserted into the slide rail, and the square plate is pushed by rotating the threaded rod to tightly fit against one side of the slide rail, thus fixing the slider in place. The slider is made of magnetic material and can be attracted to the connecting block via magnetic strips, thus firmly fixing the sealing assembly in the appropriate position. During the sealing operation of the pre-made bag, the pneumatic rod and spring work together to provide a buffering effect during the pressing process, dynamically compensating for fluctuations in heat sealing pressure and ensuring that the pressure during the sealing stage remains constant, such as maintaining it at 10–15 N / cm². 2 This design effectively reduces the possibility of poor sealing due to uneven pressure.

[0016] 2. The sealing mechanism of this horizontal pre-made bag packaging machine, through the arrangement of connecting blocks, magnetic strips, medium-density layers, sponge layers, and high-density layers, ensures precise connection between the magnetic strips fixed on the connecting blocks and the sliders during use, thereby guaranteeing a firm bond between the medium-density layer and other components. Both the medium-density and high-density layers use materials with a density of not less than 80 kg / m³. 3The polyurethane material can remain stable within the heat sealing temperature range of 150-200℃. Even after multiple compressions, it will not undergo permanent deformation, thus ensuring the reliability and consistency of the sealing process. In addition, the sponge layer has a honeycomb-shaped through-hole structure inside. The honeycomb design enhances the rapid escape channel of air during compression, avoiding uneven sealing caused by local air pressure accumulation, and further improving the sealing quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4As shown, this utility model provides a sealing mechanism for a horizontal pre-made bag packaging machine, comprising: a mounting buffer assembly 1 and an adaptive sealing assembly 2. The mounting buffer assembly 1 is composed of a base 101, a fixing block 102, a connecting plate 103, bolts 104, a pneumatic rod 105, a spring 106, a fixing plate 107, a slide rail 108, a slider 109, a square plate 1010, and a threaded rod 1011. The fixing block 102 is mounted on the side of the base 101. A connecting plate 103 is provided on the side of the connecting plate 103. A bolt 104 is installed on one side of the connecting plate 103. A pneumatic rod 105 is provided at the top of the connecting plate 103. A spring 106 is provided on the surface of the pneumatic rod 105. A fixing plate 107 is installed at the top of the pneumatic rod 105. A slide rail 108 is provided at the top of the fixing plate 107. A slider 109 is provided on the inner wall of the slide rail 108. A square plate 1010 is provided on one side of the slide rail 108. A threaded rod 1011 is installed on one side of the square plate 1010.

[0024] The sealing assembly 2 consists of a connecting block 201, a magnetic strip 202, a medium-density layer 203, a sponge layer 204, and a high-density layer 205. The connecting block 201 is installed at the top of the slider 109, and the magnetic strip 202 is installed between the connecting block 201 and the slider 109. The medium-density layer 203 is provided at the top of the connecting block 201, and the sponge layer 204 is provided above the medium-density layer 203. The high-density layer 205 is fixedly connected above the sponge layer 204. The base 101 is connected to the fixing block 102. The connecting plate 103 can be firmly fixed to one side of the fixing block 102 by rotating the bolt 104. Then, the slider 109 is inserted into the slide rail 108, and the square plate 1010 is pushed by rotating the threaded rod 1011 to make it fit tightly against one side of the slide rail 108, thereby fixing the slider 109. The slider 109 is made of magnetic material and can be attracted to the connecting block 201 via the magnetic strip 202, thereby firmly fixing the sealing assembly 2 in the appropriate position. During the sealing operation of the pre-made bag, the air pressure rod 105 and the spring 106 work together to provide a buffering effect during the pressing process of the sealing assembly 2, dynamically compensating for fluctuations in heat sealing pressure and ensuring that the pressure during the sealing stage remains constant, such as maintaining it at 10-15 N / cm. 2 This design effectively reduces the possibility of poor sealing due to uneven pressing pressure. The magnetic strip 202 fixed on the connecting block 201 is used to achieve precise connection with the slider 109, thereby ensuring a firm bond between the medium-density layer 203 and other components. Both the medium-density layer 203 and the high-density layer 205 use materials with a density of not less than 80 kg / m³. 3The polyurethane material can remain stable within the heat sealing temperature range of 150-200℃. Even after multiple compressions, it will not undergo permanent deformation, thus ensuring the reliability and consistency of the sealing process. In addition, the sponge layer 204 has a honeycomb through-hole structure inside. The honeycomb design enhances the rapid escape channel of air during compression, avoiding uneven sealing caused by local air pressure accumulation, and further improving the sealing quality.

[0025] There are two slide rails 108, which are symmetrically distributed. The symmetrical distribution of slide rails 108 can help to stably fix the sealing component 2.

[0026] There are four pneumatic rods 105, which are symmetrically distributed. The symmetrical distribution of the pneumatic rods 105 can provide a buffering effect when the sealing assembly 2 is pressed, reducing the pressure on the surface of the sealing assembly 2.

[0027] The side of the fixing block 102 is provided with a connecting groove. The bolt 104 passes through the connecting plate 103 and is connected to the fixing block 102. The bolt 104 is connected to the connecting plate 103 for connection with the fixing block 103, so that the connecting plate 103 can be fixed to the side of the device.

[0028] A fixing groove is provided on one side of the slider 109, and the threaded rod 1011 passes through the square plate 1010 and is connected to the slider 109. The threaded rod 1011 is used to fix the slider 109, and the square plate 1010 is used to limit one side of the slide rail 108.

[0029] The pore size of the sponge layer 204 is 0.5-2mm. The medium-density layer 203 and the high-density layer 205 are made of polyurethane. The pore size of the sponge layer 204 is 0.5-2mm. This pore size range can ensure that the air inside the sponge layer 204 can quickly escape through the honeycomb-shaped through holes during the sealing process.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: The base 101 is connected to the fixing block 102. By rotating the bolt 104, the connecting plate 103 can be firmly fixed to one side of the fixing block 102. Then, the slider 109 is inserted into the slide rail 108, and the square plate 1010 is pushed by rotating the threaded rod 1011 to make it fit tightly against one side of the slide rail 108, thereby fixing the slider 109. The slider 109 is made of magnetic material and can be attracted to the connecting block 201 through the magnetic strip 202, thereby firmly fixing the sealing assembly 2 in the appropriate position. When sealing the pre-made bag, during the pressing process, the air pressure rod 105 and the spring 106 work together to provide a buffering effect, dynamically compensate for the fluctuation of heat sealing pressure, and ensure that the pressure during the sealing stage remains constant, such as maintaining it at 10-15 N / cm. 2This design effectively reduces the problem of poor sealing effect caused by uneven pressing pressure;

[0032] The second step: The magnetic strip 202 fixed on the connecting block 201 is used to achieve a precise connection with the slider 109, thereby ensuring a firm bond between the medium-density layer 203 and other components. Both the medium-density layer 203 and the high-density layer 205 use materials with a density of not less than 80 kg / m³. 3 The polyurethane material can remain stable within the heat sealing temperature range of 150-200℃. Even after multiple compressions, it will not undergo permanent deformation, thus ensuring the reliability and consistency of the sealing process. In addition, the sponge layer 204 has a honeycomb through-hole structure inside. The honeycomb design enhances the rapid escape channel of air during compression, avoiding uneven sealing caused by local air pressure accumulation, and further improving the sealing quality.
