Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a horizontal sealing auxiliary flattening component. Background Technology

[0002] Existing horizontal sealing equipment suffers from two main problems during the heat sealing process: First, the heat sealing block lacks effective isolation and protection during operation, making it easy for operators to accidentally touch the high-temperature surface and suffer burns. Additionally, the packaging bag may spring back and contact the heat sealing block, causing damage. Second, during the secondary sealing of the finished bag, the bag is prone to localized bending, resulting in wrinkles in the sealing area and increasing the packaging failure rate. These problems affect operational safety and reduce packaging quality and production efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies, such as the lack of effective isolation and protection and the tendency for bags to bend locally, by proposing a horizontal sealing auxiliary flattening component.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A transverse sealing auxiliary flattening assembly includes a frame;

[0006] Two heat-sealing blocks are movably mounted on the frame via mounting bases;

[0007] Two auxiliary pressure plates are positioned above the heat-sealing block to flatten the packaging bag;

[0008] Two partitions are movably disposed on one side of the heat-sealing block to separate the heat-sealing block;

[0009] As the packaging bag passes through the frame, the partition separates the heat-sealing block to prevent accidental contact; during the heat-sealing process, the partition moves downward to avoid the heat-sealing block, and the pressure plate helps to flatten the packaging bag to reduce wrinkles.

[0010] In one possible design, cylinders are fixedly connected to both sides of the top of the frame, and the mounting base is fixedly connected to the piston end of the cylinder; a limit shaft is provided between the mounting bases to guide the movement of the mounting bases.

[0011] In one possible design, the auxiliary pressure plate includes a horizontal plate and an inclined plate. The horizontal plate has an elongated through hole. The top of the mounting base is fixedly connected with bolts. The bolts pass through the elongated through hole and are fixed to the auxiliary pressure plate with nuts.

[0012] In one possible design, the inclined plate angle of the auxiliary pressure plate is 45 degrees.

[0013] In one possible design, a guide plate is fixedly connected to the bottom of the partition, and the guide plate has a communicating oblique sliding hole and a transverse sliding hole; connecting plates are fixedly connected to both sides of the mounting base, and a guide shaft is fixedly connected to the connecting plates, the guide shaft being slidably connected to the oblique sliding hole and the transverse sliding hole; a sliding groove is provided on the inner wall of the frame, and a limiting block is fixedly connected to one end of the guide plate, the limiting block being slidably connected to the sliding groove.

[0014] In one possible design, the outer wall of the guide shaft is fitted with a bearing.

[0015] In one possible design, a heat insulation block is provided between the heat-sealing block and the auxiliary pressure plate.

[0016] In this application, during actual use, the mounting base is moved by a drive cylinder, causing the heat-sealing blocks to move towards each other to heat-seal the packaging bag. When the packaging bag passes through the frame, the partition on its side separates the heat-sealing blocks to avoid the risk of accidental contact. When the mounting base is driven to perform heat sealing, the mounting base will drive the bottom connecting plate to move. At this time, the guide shaft will be displaced inside the inclined sliding hole. The guide plate will fall naturally under gravity and move downwards together with the partition to offset the heat-sealing blocks. When the guide shaft moves into the interior of the horizontal sliding hole, the partition will be completely below the heat-sealing block. At this time, if the mounting base is driven again, the guide shaft will drive the interior of the horizontal sliding hole to move, and the two heat-sealing blocks will fit together to heat-seal the packaging bag. After the process is completed and reset, the guide shaft will abut against the inner wall of the inclined sliding hole, thereby pushing the guide plate and the upper partition to reset.

[0017] In this utility model, the horizontal sealing auxiliary flattening component, through the partition, can separate the heat sealing block when the packaging bag passes through the frame, which can effectively reduce the risk of accidental contact by the operator and the risk that the packaging bag may bounce back to the heat sealing block;

[0018] In this utility model, the horizontal sealing auxiliary flattening component can help flatten the packaging bag during the heat sealing process through the auxiliary pressure plate, reduce the occurrence of wrinkles in the packaging bag, make the heat seal more flat and firm, and improve the heat sealing effect and packaging quality.

[0019] In this invention, the partition separates the high-temperature heat-sealing block when the packaging bag passes through the frame, effectively preventing accidental contact. The auxiliary pressure plate helps to flatten the packaging bag during heat sealing, reducing wrinkles and making the heat seal smoother and more secure, thus ensuring packaging quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In one embodiment: Reference Figure 1-2 An auxiliary flattening assembly includes: a frame 1, two heat-sealing blocks 3, two auxiliary pressure plates 5, and two partitions 4, etc.

[0027] Cylinders 6 are fixedly installed on both sides of the top of the frame 1. Mounting seats 7 are also slidably installed on both sides of the top of the frame 1. The mounting seats 7 are fixedly installed with the piston end of the cylinder 6 on the same side. One mounting seat 7 has a limit shaft 8 fixedly installed at both ends on one side. The other mounting seat 7 is slidably sleeved on the outer wall of the limit shaft 8. The mounting seat 7 can be moved by the cylinder 6.

[0028] Two heat-sealing blocks 3 are fixedly installed on the side of the two mounting seats 7 that are close to each other. When the cylinders 6 on both sides are driven, the cylinders 6 drive the corresponding mounting seats 7 to move, thereby driving the two heat-sealing blocks 3 to move towards each other, so as to achieve heat sealing of the packaging bag.

[0029] The auxiliary pressure plate 5 is located above the mounting base 7 and the heat-sealing block 3 on the same side. The auxiliary pressure plate 5 includes a horizontal plate part and an inclined plate part. The surface of the horizontal plate has an elongated through hole 9. The top of the mounting base 7 is fixedly equipped with a bolt 2, and the bolt 2 is located inside the elongated through hole 9. The outer wall of the bolt 2 is fitted with a nut and a corresponding washer for fixing the auxiliary pressure plate 5. The elongated hole is used to adaptively adjust the spacing of the left and right symmetrical auxiliary pressure plates 5, thereby meeting the flattening adjustment function of large and small packaging. The angle of the inclined plate of the auxiliary pressure plate 5 is 45 degrees, which can support it during the sealing process. The auxiliary pressure plate 5 itself can help to clamp the packaging bag, reduce the phenomenon of partial bending of the finished packaging bag during secondary sealing, thereby reducing the sealing loss rate and helping to control the production cost of the enterprise.

[0030] A heat insulation block is provided between the heat sealing block 3 and the auxiliary pressure plate 5 to prevent the heat from the heat sealing block 3 from being transferred to the auxiliary pressure plate 5 and affecting the normal use of the auxiliary pressure plate 5.

[0031] This application can be used in the field of packaging equipment, or in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 3-4 A horizontal sealing auxiliary flattening component is described, which is applied in the field of packaging equipment. Two partitions 4 are located on one side of two heat-sealing blocks 3. Guide plates 14 are fixedly installed on both sides of the bottom of the partitions 4. The surfaces of the guide plates 14 are respectively provided with oblique sliding holes 12 and horizontal sliding holes 13, and the ends of the oblique sliding holes 12 and horizontal sliding holes 13 are connected. Connecting plates 10 are fixedly installed on both sides of the mounting base 7. A guide shaft 11 is fixedly installed at one end of the connecting plate 10. The guide shaft 11 is slidably connected in the oblique sliding holes 12 and horizontal sliding holes 13. In order to reduce the friction when the guide shaft 11 moves in the holes, a bearing is sleeved on the outer wall of the guide shaft 11. In addition, sliding grooves 15 are provided at both ends of the inner walls on both sides of the frame 1. A limit block is fixedly installed at one end of the guide plate 14, and the limit block is slidably installed in the adjacent sliding groove 15 to ensure the stability of the movement of the guide plate 14.

[0033] When the packaging bag passes through the frame 1, the partition 4 separates the heat sealing block 3 to avoid accidental contact; during the heat sealing process, the guide shaft 11 slides in the inclined sliding hole 12, driving the partition 4 to move downward to avoid the heat sealing block 3, while the auxiliary pressure plate 5 flattens the packaging bag to reduce wrinkles.

[0034] There is a gap between the heat-sealing block 3 and the partition 4 to ensure that the partition 4 has enough space to move vertically when the heat-sealing block 4 moves laterally.

[0035] However, as is well known to those skilled in the art, the working principle and wiring method of cylinder 6 and heat sealing block 3 are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
