Description

Technical Field

[0001] This utility model relates to a bag making machine, and more particularly to an integrated gluing and bag making machine. Background Technology

[0002] A gluing and bag-making integrated machine is a device that produces bags from plastic films or composite materials. It typically includes multiple processes such as gluing, heat sealing, and cutting. Among these processes, gluing is a crucial step, directly affecting the bag's sealing performance and overall quality.

[0003] Traditional integrated gluing and bag-making machines typically use a single glue outlet for gluing. When processing wide materials, the amount of glue applied to the edges may be less than that in the center, leading to poor sealing during heat sealing, affecting product quality and user experience. Secondly, production efficiency is low; the gluing speed of a single outlet is slow, which in turn affects material transport speed, hindering mass production, increasing production costs and delivery cycles. Furthermore, maintenance is difficult; the single-outlet design makes maintenance and cleaning challenging, especially when the outlet is clogged, requiring more time and effort to clean, increasing maintenance costs and failure rates. Additionally, the glue outlet position of conventional single-outlet gluing and bag-making machines needs to be manually adjusted according to the material's position, resulting in poor adaptability and difficulty in flexibly adjusting to accommodate materials of different thicknesses and materials, limiting the equipment's application range. Utility Model Content

[0004] To overcome the shortcomings of traditional gluing and bag-making machines that typically use a single glue outlet for gluing, which may result in less glue applied to the edges than the center when handling wide materials, leading to poor sealing during heat sealing and affecting product quality and user experience; secondly, low production efficiency, as the gluing speed of a single outlet is slow, thus affecting material transport speed and hindering mass production, increasing production costs and delivery cycles; furthermore, difficult maintenance, as the single outlet design makes maintenance and cleaning challenging, especially when the outlet is clogged, requiring more time and effort to clean, increasing maintenance costs and failure rates; and thirdly, the position of the glue outlet in conventional single-outlet gluing and bag-making machines needs to be manually adjusted according to the material position, resulting in poor adaptability and difficulty in flexibly adjusting to materials of different thicknesses and materials, limiting the application range of the equipment, the aim is to provide a gluing and bag-making machine that can automatically change the glue injection position, has multiple glue outlets, achieves more uniform gluing, accelerates gluing speed, and enhances adaptability.

[0005] The technical solution of this utility model is: an integrated gluing and bag making machine, comprising a base 1, a base 2, a material transfer roller group, a hot melt component, a pressing roller, a glue tank, a transmission component, a slider, a pipe, a glue injection block, a glue extraction pump, a bracket, a platform, a cutter, and a lifting drive component. Base 1 is connected to Base 2 on its right side. Control cabinets are located on the front sides of both base 1 and Base 2. A material transfer roller group is located on the right side of Base 2, consisting of multiple rollers arranged in the same direction. A hot melt component is located inside Base 1. Multiple pressing rollers are arranged on the right side of Base 1 near Base 2, each consisting of two pressing rollers with their outer sides close to each other. A glue tank is located at the rear of Base 2. A transmission component is located on the upper left side of Base 2, with a slider mounted on the transmission component. A glue injection block is located below the slider, and a glue extraction pump is located on the upper rear side of the glue injection block. The input of the glue extraction pump... The base is connected to a pipe, one end of which extends into the glue tank. Multiple glue inlets are located on the front of the glue block. The glue block contains glue transfer channels, the number of which corresponds to the number of glue inlets. Each glue transfer channel corresponds to one of the glue inlets. The other end of each glue transfer channel is connected to the output of a glue pump. The glue pump extracts glue from the glue tank and discharges it through the glue inlets. A slider on the transmission component moves back and forth under the transmission of the transmission component, thus moving the glue block back and forth. A bracket is located on the left side of the base, with a lifting drive component on it. A cutter is mounted on the lifting drive component, which moves the cutter up and down. A platform is located on the left side of the base, directly below the cutter. When the cutter moves down, it contacts the top of the platform. The cooperation between the cutter and the platform enables the cutting of the material.

[0006] Furthermore, it also includes a heating box. The pipeline is equipped with a heating box. Before the glue in the glue box enters the glue injection block, it will pass through the heating box first. The glue is heated in the heating box and then discharged.

[0007] Furthermore, it also includes a roller plate. The roller plate is rotatably mounted on the side of the base two near the glue injection block. During material transfer, the edges of the two single-layer materials that need to be bonded together will slide across the upper and lower surfaces of the roller plate.

[0008] Furthermore, it also includes a negative pressure valve. The dispensing block is equipped with a negative pressure valve, and the negative pressure valve has an airflow channel inside. The airflow channel inside the negative pressure valve is connected to a section of the path between the negative pressure valve and all dispensing channels.

[0009] Furthermore, it also includes a rotating shaft and a conveyor belt. Two rotating shafts are rotatably provided on the left side of the base, and multiple conveyor belts are evenly spaced around the outer sides of the rotating shafts.

[0010] Furthermore, it also includes a loading platform, a transfer frame, rotating rollers, a folding triangle frame, and a feeding roller. The loading platform is located on the right side of the base, and the transfer frame is located behind the loading platform. Two rotating rollers are located on the upper part of the transfer frame, and a folding triangle frame is located in front of the rotating rollers on the lower side. The feeding rollers are located on the loading platform. There are two feeding rollers, and the feeding rollers are arranged in the same direction as the rollers on the transfer roller group. The continuously transported material passes through the space between the two rotating rollers and covers the folding triangle frame. The folding triangle frame folds the transported material in half. The folded material passes downward between the feeding rollers and is introduced to the right into the transfer roller group. The material passes through the processing areas of the rolling plate, the glue injection block, the pressing roller, the hot melt part, and the cutter in sequence to the right.

[0011] The beneficial effects of this invention are as follows: By setting a movable glue-dispensing block, the position of the block can be flexibly adjusted according to the different locations of the material during glue application, ensuring uniform glue application. Furthermore, the multiple glue-dispensing ports enable simultaneous glue application at multiple points, effectively improving glue application speed and quality, reducing uneven glue application at material edges and centers, and enhancing the sealing performance and overall quality of the bag. Simultaneously, the multi-port design also reduces maintenance difficulty and improves equipment adaptability and production efficiency.

[0012] This invention incorporates a heating box along the adhesive's transport path. By heating the adhesive before it is discharged, it ensures that the adhesive maintains a suitable temperature and fluidity during discharge, preventing problems such as adhesive solidification and poor fluidity caused by excessively low temperatures. This improves the uniformity and quality of adhesive application, enhances the sealing performance after bonding, reduces adhesive blockage, extends the service life of the equipment, and increases overall production efficiency.

[0013] This invention uses a roller plate to spread the edge of the material to be bonded at a certain angle, so that when the subsequent material passes through the top and bottom sides of the glue dispensing block, a gap is formed between it and the glue outlet of the glue dispensing block. This reduces glue blockage caused by the material contacting the pre-gluing outlet, ensures more uniform glue application, improves the quality and stability of material bonding, reduces the generation of bubbles and wrinkles, and enhances the appearance and sealing performance of the final product.

[0014] This invention incorporates a negative pressure valve in the glue transfer channel at the glue outlet. When glue application is interrupted, the valve intervenes promptly, drawing back the glue from the outlet through negative pressure to prevent excess glue from dripping. This effectively avoids glue waste and pollution of the working environment, while ensuring the cleanliness and continuity of the glue application process. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0023] Example 1: An integrated gluing and bag-making machine, such as... Figure 1-5As shown, the system includes a base 1, a base 2, a material transfer roller assembly 3, a hot melt component 31, a pressing roller 32, a glue tank 5, a transmission component 51, a slider 52, a pipe 53, a glue injection block 54, a glue extraction pump 55, a bracket 6, a platform 61, a cutter 62, and a lifting drive component 63. The right side of the base 1 is connected to the base 2. Both the base 1 and base 2 have control cabinets on their front sides for easy monitoring and control of the operation of each component. The right side of the base 2 has the material transfer roller assembly 3, which consists of multiple rollers arranged in the same direction, ensuring smooth and stable material transfer. The offset improves the precision and quality of bag making. The base 1 is equipped with a heat-melting component 31 to heat the material to a suitable temperature so that the glue can bond better and improve the bonding effect. Multiple pressing rollers 32 are arranged on the right side of the base 1 near the base 2. Each pressing roller 32 consists of two rollers with their outer sides close to each other. Through the action of the pressing rollers 32, the edges of the material can be tightly attached to prevent air from entering and improve the sealing performance of the finished product. The rear of the base 2 is equipped with a glue box 5 for storing glue, ensuring the continuity and stability of glue supply. A transmission component 51 is located on the upper left side of the base 2. A slider 52 is mounted on the transmission component 51, and a glue injection block 54 is located below the slider 52. A glue pump 55 is located on the upper rear side of the glue injection block 54. The input end of the glue pump 55 is connected to a pipe 53, one end of which extends into the glue tank 5. The glue pump 55 draws out the glue from the glue tank 5 and discharges it through the glue injection port, ensuring that the glue is evenly distributed on the material, thus improving the uniformity and efficiency of glue application. The edges of folded or two single-layer materials that need to be bonded will pass through the upper and lower sides of the glue injection block 54 respectively. The front side of the glue injection block 54 has multiple glue injection ports, and the inside of the glue injection block 54 has glue transfer channels that match the number of glue injection ports. Each glue transfer channel corresponds to one glue injection port, and the other end of each glue transfer channel is connected to the output end of the glue pump 55. This design ensures that each glue injection port receives a stable flow of glue, further improving the quality of glue application. The slider 52 moves back and forth under the transmission of the transmission component 51, which in turn drives the glue injection block 54 to move back and forth, so that the glue injection block 54 can be accurately positioned and glued on the material, increasing the flexibility and adaptability of bag making. The left side of the base 1 is provided with a bracket 6, and the bracket 6 is provided with a lifting drive component 63. The lifting drive component 63 is provided with a cutter 62. The cutting blade 62 is driven to move up and down by the lifting drive component 63. The left side of the base 1 is provided with a pad 61, which is located directly below the cutter 62. When the cutter 62 moves down, it will contact the top of the pad 61. Through the cooperation of the cutter 62 and the pad 61, the material is accurately cut, ensuring that the size of each piece of material is consistent, improving the consistency and aesthetics of bag making. Through the synergistic effect of the above components, this glue application and bag making integrated machine not only realizes the efficient glue application and bag making process, but also significantly improves the quality of the finished product and production efficiency.

[0024] The material processing steps are as follows: First, the material is smoothly conveyed to the glue injection block 54 by the conveyor roller group 3. The glue pump 55 draws glue from the glue tank 5 through the pipe 53 and delivers it to multiple glue injection ports of the glue injection block 54. Then, the glue injection block 54 slides under the drive of the transmission component 51 to ensure that the glue is evenly distributed on the material, improving the uniformity and efficiency of glue application. The hot melt component 31 heats the material to reach a suitable temperature so that it can better bond with the glue. Next, the material passes through multiple pressing rollers 32. The pressing rollers 32 are composed of two pressure rollers with their outer sides close to each other to ensure that the edges of the material are tightly bonded, preventing air from entering and improving the sealing performance of the finished product. Finally, the material is conveyed to the bottom of the cutter 62. The cutter 62 moves up and down repeatedly under the drive of the lifting drive component 63, cooperating with the pad 61 to achieve precise cutting of the material.

[0025] Example 2: Based on Example 1, such as Figure 2 and Figure 3 As shown, it also includes a heating box 56. The heating box 56 is installed on the pipeline 53. Before the glue in the glue box 5 enters the glue injection block 54, it will pass through the heating box 56 first. The glue is heated in the heating box 56 and then passed out, ensuring that the glue maintains an appropriate temperature before being injected into the material, improving the fluidity and bonding effect of the glue, thereby enhancing the bonding strength and durability of the finished product.

[0026] In addition, such as Figure 2 As shown, it also includes a roller disc 4. The roller disc 4 is rotatably mounted on the side of the base 2 near the glue injection block 54. During material transfer, the edges of the two single-layer materials that need to be bonded together will slide across the upper and lower surfaces of the roller disc 4. The roller disc 4 opens the edge of the single-sided material that needs to be bonded at a certain angle, so that when the subsequent material passes through the upper and lower sides of the glue injection block 54, a gap is formed between it and the glue outlet of the glue injection block 54, reducing glue blockage caused by the contact of the material pre-gluing outlet, ensuring more uniform glue application, improving the quality and stability of material bonding, reducing the generation of bubbles and wrinkles, and improving the appearance and sealing performance of the final product.

[0027] In addition, such as Figure 3 and Figure 4 As shown, it also includes a negative pressure valve 7. The glue dispensing block 54 is equipped with a negative pressure valve 7. The negative pressure valve 7 has an airflow channel inside. The airflow channel inside the negative pressure valve 7 is connected to a section of all glue transfer channels. Through the action of the negative pressure valve 7, after the glue is applied, the remaining glue in the glue transfer channel can be quickly sucked into the glue storage device to prevent the glue from dripping from the glue outlet, keep the working environment clean, and avoid glue waste.

[0028] like Figure 1 and Figure 5As shown, it also includes a rotating shaft 8 and a conveyor belt 81. Two rotating shafts 8 are rotatably provided on the left side of the base 1. The design of these two rotating shafts 8 allows the conveyor belt 81 to rotate smoothly, ensuring that the material will not deviate or jam during the conveying process. Multiple conveyor belts 81 are evenly spaced around the outer side of the rotating shafts 8. The conveyor belts 81 maintain a smooth and uniform speed during the conveying process, avoiding wrinkles or damage to the material caused by inconsistent speed. The cut material is continuously conveyed outward through the conveyor belts 81, ensuring that the material can be smoothly output from the machine, facilitating subsequent collection and processing, and improving the continuity and efficiency of the entire bag making process.

[0029] In a preferred embodiment: such as Figure 1 and Figure 6 As shown, it also includes a loading platform 9, a transfer frame 91, rotating rollers 92, a folding triangle 93, and a feeding roller 94. The loading platform 9 is located on the right side of the base 2, and the transfer frame 91 is located at the rear of the loading platform 9. The design of the transfer frame 91 can guide the material smoothly into the subsequent processing stage, reducing the resistance and wear of the material during the transmission process. Two rotating rollers 92 are located on the upper part of the transfer frame 91. The design of these two rotating rollers 92 can ensure that the material maintains uniform tension during the transmission process, avoiding material slack or excessive stretching, thereby ensuring the flatness and stability of the material. A folding triangle 93 is located on the front side of the lower rotating roller 92. The folding triangle 93 folds the two edges of a continuously transmitted material in half. The folding triangle 93 is triangular or similar in shape and has a certain tilt angle. When the film material passes between the two rotating rollers 92 and covers the folding triangle 93, The film material is forced to gradually fold along the inclined surface of the folding triangle 93. The loading platform 9 is equipped with two feeding rollers 94, and the feeding rollers 94 are arranged in the same direction as the rollers on the transfer roller group 3, which ensures the consistency of the material direction during the transfer process, avoids the twisting or deviation of the material, and further improves the accuracy and stability of the material transfer. The continuously transferred material passes between the two rotating rollers 92 and covers the folding triangle 93. The folding triangle 93 folds the transferred material in half, and the folded material passes downward between the feeding rollers 94 and is introduced to the right into the transfer roller group 3. The material passes through the processing areas of the rolling plate 4, the glue injection block 54, the pressing roller 32, the hot melt part 31, and the cutter 62 in sequence. This series of designs ensures that the entire process from material loading to final processing is smooth and efficient, improving production efficiency and finished product quality.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
