Description

Technical Field

[0001] This utility model relates to the field of packaging machine forming equipment technology, and in particular to an adjustable vertical packaging machine forming equipment. Background Technology

[0002] The forming unit of a vertical packaging machine is one of its core components. Its main function is to shape packaging materials (such as film) into a bag-like structure using a mold of a specific shape, preparing for subsequent filling and sealing processes. In industries such as food, pharmaceuticals, and chemicals, the forming unit plays a particularly crucial role, directly affecting the forming quality and packaging efficiency of the bags, as follows.

[0003] A search revealed patent CN217171125U, which discloses a forming device for a large-format vertical automatic powder packaging machine, belonging to the technical field of powder flexible packaging equipment. This device reduces the impact of powder on the bottom of the packaging bag. The technical solution is as follows: a crossbeam is connected between two supporting wall plates; a feeding cylinder is bolted to the crossbeam; the lower end of the feeding cylinder is connected to the forming cylinder via a flange; a buffer is installed in the lower part of the forming cylinder, consisting of a rotating rod and a blocking plate; the two ends of the rotating rod are rotatably connected to the opposite side walls of the forming cylinder; the blocking plate is fixedly connected to the rotating rod; and heat-sealing clamps are located directly below the forming cylinder, with both ends fixed to the supporting wall plates on both sides. This invention has a simple structure and is easy to operate. The buffer prevents the bottom seal of the packaging bag from being broken or partially broken by the impact of falling powder during the filling process in large-format vertical automatic powder packaging machines, thus improving production efficiency and product quality.

[0004] However, the above-mentioned packaging machine forming device still has the following areas for optimization. For example, the forming cylinder is fixedly connected to the lower end of the feeding cylinder through a flange. The flange connection usually requires multiple locking bolts and nuts, which makes it easy to quickly disassemble and replace the forming cylinder with different specifications and sizes. Disassembly and reinstallation are time-consuming and labor-intensive, resulting in low efficiency. This makes it inconvenient to change and adjust the specifications and sizes of the forming cylinder, and consequently, it makes it inconvenient to carry out packaging work of different specifications and sizes. Therefore, there is an urgent need for an adjustable vertical packaging machine forming device to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model discloses an adjustable vertical packaging machine forming device. It features a forming mechanism that allows the plastic packaging film to smoothly wrap around the forming cylinder during machine operation. A heat-sealing component then heat-seals the bottom of the film to form a packaging bag. After each bag is heat-sealed, powder falls from the feeding cylinder into the forming cylinder and then into the packaging bag, completing the powder filling process. When it is necessary to change or adjust the size of the forming cylinder, two pull rods can be pulled up, compressing springs and causing two abutment plates and limit blocks to move until the two limit blocks separate from their respective limit grooves. When needed, the docking seat and forming cylinder can be quickly and easily removed and replaced with the forming cylinder of the required specifications and dimensions. During installation, keep the pull rod in the pulled state, match and engage the two docking plates at the top of the docking seat with the two docking slots, then release the two pull rods. The spring will return, and in conjunction with the abutment plate, it will drive the limiting plate to match and engage with the limiting slot, thus completing the installation quickly and easily. In this way, it is possible to quickly disassemble and replace forming cylinders of different specifications and dimensions, so that the device can be used for different packaging needs, greatly improving the applicability of the device. In summary, the problems in the background technology are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The adjustable vertical packaging machine forming device of this utility model includes a support plate. There are two support plates, which are fixedly connected by a top seat. The top seat is close to the top of the support plate. A feed cylinder is fixedly installed through the top seat. The bottom of the feed cylinder is connected to a connecting seat. The connecting seat has two docking slots. The two docking slots are symmetrically distributed on both sides of the feed cylinder. A heat sealing assembly is fixedly installed between the two support plates.

[0008] A molding mechanism includes a molding cylinder and a fixed base. The top of the molding cylinder is connected to a docking seat. Two docking plates are fixedly connected to the top of the docking seat. The docking plates match and engage with docking slots. The top of the docking seat is tightly fitted to the bottom of the connecting seat. A through-hole limiting groove is opened inside the docking plates. Two fixed bases are provided, and both fixed bases are fixedly installed on the top of the connecting seat. An L-shaped pull rod is movably connected through the fixed base. One end of the pull rod is rotatably connected to an abutment plate through a rotating connector. A limiting plate is fixedly connected to one side of the abutment plate. The limiting plate matches and engages with a limiting groove. Multiple springs are fixedly connected to the other side of the abutment plate. The other end of the springs is fixedly connected to the fixed base.

[0009] A buffer mechanism is located inside the feed cylinder and the forming cylinder.

[0010] Furthermore, an annular sealing gasket is fixedly attached to the top of the docking seat, and the top of the sealing gasket is tightly attached to the bottom of the connecting seat.

[0011] Furthermore, the bottom of the abutment plate fits against the top of the connecting seat, and the bottom of the abutment plate is a smooth surface.

[0012] Furthermore, grooves are provided on both sides of the connecting seat, and the position and size of the grooves match the position and size of the pull rod.

[0013] Furthermore, the buffer mechanism includes a first buffer plate and a second buffer plate. The first buffer plate is fixedly connected to the inside of the feed cylinder. There are four second buffer plates, each fixedly connected to the inner wall of the forming cylinder. The height of the four second buffer plates decreases sequentially from top to bottom, and they are located sequentially from top to bottom towards the left side, back side, right side, and front side of the forming cylinder. The size of the first buffer plate is smaller than the internal size of the feed cylinder, and the size of the second buffer plate is smaller than the internal size of the forming cylinder. Both the first and second buffer plates are designed at an angle. The first buffer plate is inclined towards the second buffer plate at the top, and the ends of the multiple second buffer plates near the center of the forming cylinder are inclined downwards.

[0014] Furthermore, both the first and second buffer sheets are made of stainless steel, and the outer surfaces of both the first and second buffer sheets are smooth.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution features a forming mechanism that allows the plastic packaging film to be smoothly wrapped around the forming cylinder during packaging machine operation. The bottom of the packaging film is then heat-sealed by the heat-sealing component to form a packaging bag. After each packaging bag is heat-sealed, the powder falls from the feeding cylinder into the forming cylinder and then into the packaging bag, completing the powder filling. When it is necessary to change or adjust the size of the forming cylinder, different sizes of forming cylinders can be quickly disassembled and replaced to adapt the device to different packaging needs, greatly improving the applicability of the device. Furthermore, no matching disassembly and installation tools are required, making disassembly and installation time-saving and labor-saving, with high efficiency and overall high practicality.

[0017] 2. This technical solution incorporates a buffer mechanism, which allows for multi-stage buffering of the powder during feeding. This significantly reduces the impact force, making it less likely to damage the packaging bag. Furthermore, because the impact force is gradually reduced, the impact of the powder on the first and second buffers is smaller, minimizing the risk of damage to the first and second buffers and extending their overall service life. In summary, this further improves the practicality of the device. Attached Figure Description

[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. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 An adjustable vertical packaging machine forming device includes a support plate 1. There are two support plates 1, which are fixedly connected by a top seat 2. The top seat 2 is close to the top of the support plate 1. A feed cylinder 3 is fixedly installed through the top seat 2. A connecting seat 4 is connected to the bottom of the feed cylinder 3. Two docking slots 5 are opened at the connecting seat 4. The two docking slots 5 are symmetrically distributed on both sides of the feed cylinder 3. A heat sealing assembly 6 is fixedly installed between the two support plates 1.

[0029] The molding mechanism 7 includes a molding cylinder 701 and a fixing base 702. A docking seat 703 is connected to the top of the molding cylinder 701. Two docking plates 704 are fixedly connected to the top of the docking seat 703. The docking plates 704 match and engage with the docking slots 5. The top of the docking seat 703 is tightly fitted to the bottom of the connecting base 4. A through-hole limiting groove 705 is provided inside the docking plate 704. Two fixing bases 702 are provided, both of which are fixedly installed on the connecting base 4. At the top, an L-shaped pull rod 706 is movably connected through the fixed seat 702. One end of the pull rod 706 is rotatably connected to an abutment plate 707 via a rotating connector. A limit plate 708 is fixedly connected to one side of the abutment plate 707. The limit plate 708 matches and engages with the limit groove 705. Multiple springs 709 are fixedly connected to the other side of the abutment plate 707. The other end of the springs 709 is fixedly connected to the fixed seat 702. A buffer mechanism 8 is located inside the feed cylinder 3 and the forming cylinder 701.

[0030] An annular sealing gasket 710 is fixedly attached to the top of the docking seat 703, and the top of the sealing gasket 710 is tightly attached to the bottom of the connecting seat 4; the bottom of the abutment plate 707 is attached to the top of the connecting seat 4, and the bottom of the abutment plate 707 is a smooth surface; grooves 9 are provided on both sides of the connecting seat 4, and the position and size of the grooves 9 match the position and size of the pull rod 706.

[0031] In the specific implementation process, when the packaging machine is running, the plastic packaging film is smoothly wrapped around the forming cylinder 701, and the bottom of the packaging film is heat-sealed by the heat-sealing component 6 to form a packaging bag. After each packaging bag is heat-sealed, the powder will fall from the feeding cylinder 3 into the forming cylinder 701, and then into the packaging bag to complete the powder filling. When it is necessary to change or adjust the specifications and dimensions of the forming cylinder 701, the two pull rods 706 can be pulled up to compress the spring 709, which will drive the two abutment plates 707 and the limit blocks to move until the two limit blocks separate from the two limit grooves 705 respectively. At this time, it can be quickly and easily moved down. Remove the docking seat 703 and the forming cylinder 701, and replace it with the forming cylinder 701 of the required specifications and dimensions. During installation, keep the pull rod 706 in the pulled state, match and engage the two docking plates 704 at the top of the docking seat 703 with the two docking slots 5, and then release the two pull rods 706. The spring 709 will rebound, and in conjunction with the abutment plate 707, it will drive the limiting plate 708 to match and engage with the limiting groove 705. This allows for quick and convenient installation. In this way, it is possible to quickly disassemble and replace the forming cylinder 701 of different specifications and dimensions, so that the device can be used for different packaging needs, greatly improving the applicability of the device.

[0032] The sealing gasket 710 is used to improve the sealing performance between the mating seat 703 and the connecting seat 4, and to prevent material leakage.

[0033] The bottom of the abutment plate 707 is attached to the top of the connecting seat 4 to limit the movement of the abutment plate 707, so that it can only move horizontally and cannot rotate. The bottom of the abutment plate 707 is a smooth surface to reduce the friction and wear between the abutment plate 707 and the connecting seat 4 and extend its service life.

[0034] The groove 9 is designed so that after the lever 706 is pulled up, it can be rotated and locked in the groove 9, freeing the operator's hands and facilitating other operations. Specific Implementation Example 2:

[0036] Reference Figure 1 and Figure 5In a preferred embodiment, the buffer mechanism 8 includes a first buffer plate 801 and a second buffer plate 802. The first buffer plate 801 is fixedly connected to the inside of the feed cylinder 3. There are four second buffer plates 802, and each of the four second buffer plates 802 is fixedly connected to the inner wall of the forming cylinder 701. The height of the four second buffer plates 802 decreases from top to bottom, and the four second buffer plates 802 are located from top to bottom to the left, back, right and front of the forming cylinder 701. The size of the first buffer plate 801 is smaller than the internal size of the feed cylinder 3, and the size of the second buffer plate 802 is smaller than the internal size of the forming cylinder 701. Both the first buffer plate 801 and the second buffer plate 802 are designed at an angle. The first buffer plate 801 is inclined toward the second buffer plate 802 at the top, and the ends of the multiple second buffer plates 802 near the center of the forming cylinder 701 are all inclined downward.

[0037] Both the first buffer sheet 801 and the second buffer sheet 802 are made of stainless steel, and the outer surfaces of both the first buffer sheet 801 and the second buffer sheet 802 are smooth.

[0038] In the specific implementation process, when feeding, the powder first enters the feeding cylinder 3. Some of the powder will directly pass through the feeding cylinder 3 and contact the second buffer plate 802 at the top. Another part of the powder will first contact the first buffer plate 801, and then slide down to contact the second buffer plate 802 at the top, forming the first step of buffering. Subsequently, the powder will slide down to contact the remaining three second buffer plates 802 below one by one and form buffers. Thus, before the powder comes into contact with the packaging bag, it can be initially buffered after entering the feeding cylinder 3. Then it enters the forming cylinder 701 for multi-stage further buffering. As a result, when the powder slides down to contact the bottom of the packaging bag, the impact force is greatly reduced, and it is not easy to damage the packaging bag. Since the impact force is weakened step by step, the impact force of the powder on the first buffer plate 801 and multiple second buffer plates 802 is small, and it is not easy to damage the first buffer plate 801 and the second buffer plate 802, thus extending its overall service life.

[0039] The first buffer plate 801 and the second buffer plate 802 are both made of stainless steel so that the first buffer plate 801 and the second buffer plate 802 have high rigidity and are not easily deformed or damaged. The outer surfaces of the first buffer plate 801 and the second buffer plate 802 are smooth to reduce the friction between them and the powder, so that the powder can slide off and be discharged easily.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
