Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the production technical field of drawing type towel, concretely relates to a drawing type towel heat sealing packaging mechanism. BACKGROUND

[0002] In the production field of drawing type towel, the packaging process has a significant impact on product quality and production efficiency. In the past, the distribution of drawing type towel was mostly completed manually or with the help of simple mechanical devices. Manual distribution is easily disturbed by factors such as worker fatigue and mood, resulting in low distribution efficiency and difficulty in ensuring consistent quantity and interval of feeding, which leads to a lack of coherence in the production process. Even simple mechanical devices are difficult to accurately control the distribution rhythm due to design limitations, affecting the overall packaging progress. In terms of rolling and air exhausting, conventional operation methods cannot penetrate the inside of the packaging bag, causing air to remain. During subsequent heat sealing, the remaining air expands when heated, which easily causes the sealing part to bulge and rupture, greatly shortening the shelf life of the drawing type towel and reducing product quality.

[0003] The heat sealing process also has many problems. Traditional heat sealing equipment lacks temperature control precision, and the heat sealing knife pressure is uneven, which causes the seal to be not tight, the product to be easily damp and deteriorated, and the defective rate to be high. Moreover, the distribution, rolling and air exhausting, and heat sealing processes are relatively independent, lack effective linking mechanisms, and cannot achieve continuous and smooth packaging operations. Frequent stoppage for adjustment seriously restricts production efficiency and cannot meet the market demand for high-quality products.

[0030] Referring to the accompanying Figures 1-4A pull-out towel heat-sealing packaging mechanism includes a conveyor belt 1. A material distribution module 2, a rolling module 3, and a heat-sealing module 4 are respectively arranged at the upper and lower ends of the conveyor belt 1. A linkage frame 5 is provided between the rolling module 3 and the heat-sealing module 4. The heat-sealing module 4 is located on one side of the rolling module 3. The rolling module 3 includes a pressure roller assembly 301, an X-axis moving mechanism 302, and a Z-axis moving mechanism 303. The heat-sealing module 4 includes a heat-sealing knife 401 and a hot-pressing cylinder 402. The material distribution module 2 is arranged near one end of the conveyor belt 1. The material distribution module 2 includes a material distribution cylinder 201 and a flipping and blocking assembly 202. The linkage frame 5 includes a suspension frame 501, a lifting frame 502, and a rolling slide 503.

[0031] The linkage frame 5 consists of a suspension frame 501, a lifting frame 502, and a rolling slide 503. The suspension frame 501 and the lifting frame 502 are connected by the rolling slide 503. The upper end of the suspension frame 501 is provided with a mounting plate 6. The rolling module 3 is set inside the suspension frame 501, and the heat sealing module 4 is set inside the lifting frame 502. The rolling slide 503 is L-shaped in general and includes a vertical slide and a horizontal slide. The vertical slide and the horizontal slide are connected. The linkage frame 5, the rolling module 3, and the heat sealing module 4 are fixedly installed above the conveyor belt 1 by the mounting plate 6 on the suspension frame 501 and the mounting plates 7 on both sides of the lifting frame 502. The rolling slide 503 is used to cooperate with the extrusion roller 3011 in the rolling module 3 to achieve downward and forward movements.

[0032] The rolling die 3 consists of a pressure roller assembly 301, an X-axis moving mechanism 302, and a Z-axis moving mechanism 303. The Z-axis moving mechanism 303 includes a first Z-axis push cylinder 3031 and a second Z-axis push cylinder 3032 fixed to both sides and the rear end of the suspension frame 501. The piston end of the first Z-axis push cylinder 3031 is connected to a limit stop 3033. The first Z-axis push cylinder 3031 is located near the vertical slide rail. The pressure roller assembly 301 includes a squeeze roller 3011 and a sliding frame 3012. After being pressed downward by the Z-axis moving mechanism 303, the extrusion roller 3011 moves to the bottom along the vertical slide of the rolling slide 503, and is then pushed out by the X-axis moving mechanism 302, causing the extrusion roller 3011 to move horizontally along the transverse slide. Both ends of the sliding frame 3012 are equipped with guide rods 3013 that penetrate the rolling slide 503, and limit blocks 3033 are located at the lower ends of the guide rods 3013. The Z-axis moving mechanism 303 uses two Z-axis push cylinders 3031 to push the extrusion roller 3011 downward or... The upward pushing action is simultaneously transmitted through the Z-axis push cylinder 3032, which acts on the X-axis push cylinder 3021, causing it to move up and down together with the extrusion roller 3011. The X-axis moving mechanism 302 includes the X-axis push cylinder 3021, with a telescopic spring column 3022 at its end. The telescopic spring column 3022 is located at the lower end of the X-axis push cylinder 3021 and is embedded in the rear end of the suspension frame 501. The Z-axis push cylinder 3032 is located at the upper end of the X-axis push cylinder 3021 and its movement is... The plug end is in contact with the X-axis push cylinder 3021. The piston end of the X-axis push cylinder 3021 is fixedly connected to the sliding frame 3012. The X-axis push cylinder 3021 moves up and down simultaneously with the extrusion roller 3011 through the Z-axis push cylinder 3032, and automatically moves up to reset through the telescopic spring column 3022. The pressure roller assembly 301 extrudes and rolls the packaging bag to expel air through the Z-axis moving mechanism 303 and the X-axis moving mechanism 302, which facilitates heat sealing of the packaging.

[0033] Two guide rods 403 and 404, which pass through the lifting frame 502, are respectively provided on the upper end and both sides of the heat sealing knife 401. The hot pressing cylinder 402 is fixed on the upper end of the lifting frame 502 and its piston end is fixedly connected to the heat sealing knife 401. The lifting frame 502 has lifting limit grooves 5021 on both sides. The second mounting plate 7 is provided above the lifting limit grooves 5021. The guide rod 404 passes through the lifting limit grooves 5021. The heat sealing knife 401 is lifted and lowered by the hot pressing cylinder 402. After descending to a certain height, it heat-seales the packaging bag that has been rolled and degassed on the conveyor belt 1.

[0034] The material distribution module 2 is located at one end of the conveyor belt 1. After the material distribution cylinder 201 in the material distribution module 2 pushes the flipping and blocking component 202, it blocks the conveyor belt 1 from the connected production line, thereby achieving the function of material distribution.

[0035] In this embodiment, the method and steps are as follows;

[0036] Preparation: Ensure that all modules of the equipment are installed correctly and that all components are securely connected. Check that the conveyor belt 1 runs smoothly and that all power components such as cylinders and motors are properly powered and in their initial state.

[0037] Material sorting operation:

[0038] When the towel products are conveyed to one end of conveyor belt 1 along the production line, the material distribution module 2 is activated.

[0039] The distributing cylinder 201 operates, pushing the flipping and blocking component 202 to block the conveyor belt 1 from the connected production line. By controlling the stroke and operating frequency of the distributing cylinder 201, the towel products are released one by one onto the conveyor belt 1 according to a predetermined quantity or interval, thus completing the distributing process.

[0040] Roller venting operation:

[0041] The towel products that have been distributed onto conveyor belt 1 move along the conveyor belt to the area below the rolling module 3;

[0042] The Z-axis moving mechanism 303's Z-axis push cylinder 1 3031 and Z-axis push cylinder 2 3032 start working. The piston end of Z-axis push cylinder 1 3031 extends out, pushing the limit block 3033 to move down, which in turn drives the extrusion roller 3011 in the pressure roller assembly 301 to move down along the vertical slide of the rolling slide 503, and to perform preliminary extrusion on the packaging bag containing towels on the conveyor belt.

[0043] After the extrusion roller 3011 moves to the bottom along the vertical slide, the X-axis push cylinder 3021 in the X-axis moving mechanism 302 starts to work. The piston end of the X-axis push cylinder 3021 extends and pushes the sliding frame 3012, causing the extrusion roller 3011 to move horizontally along the transverse slide of the rolling slide 503. During the horizontal movement, the packaging bag is rolled and squeezed to expel the air inside the packaging bag. During this process, the Z-axis push cylinder 3032 acts on the X-axis push cylinder 3021, causing it to move up and down together with the extrusion roller 3011. The X-axis push cylinder 3021 is automatically reset by the telescopic spring column 3022, preparing for the next rolling and air exhaust.

[0044] Heat sealing operation:

[0045] After the packaging bag has completed the rolling and degassing process, it moves along conveyor belt 1 to the area below heat sealing module 4.

[0046] When the hot-press cylinder 402 is working, its piston end extends out and pushes the heat-sealing knife 401 to move downward along the guide rod 2 403 and the guide rod 3 404. The guide rod 3 404 slides in the lifting limit groove 5021 on both sides of the lifting frame 502 to ensure the smoothness of the descent process of the heat-sealing knife 401.

[0047] After the heat sealing blade 401 descends to a certain height, it performs heat sealing on the packaging bag that has already been rolled and degassed on the conveyor belt, ensuring the packaging bag is completely sealed. After heat sealing is completed, the piston end of the heat sealing cylinder 402 retracts, causing the heat sealing blade 401 to rise and reset.

[0048] Finished product output: After heat sealing, the finished towel packaging continues to be conveyed by conveyor belt 1 to the next process or the finished product collection area, completing the entire pull-out towel heat sealing packaging process. During this process, the above-mentioned steps of material distribution, rolling degassing, and heat sealing are repeated to achieve continuous packaging operations.

[0049] In summary, the pull-out towel heat-sealing packaging mechanism precisely controls product feeding through the material distribution module, ensuring accurate quantity and spacing. The rolling module efficiently removes air from the packaging bag, facilitating heat sealing. The heat-sealing module is stable and reliable, guaranteeing sealing quality. The entire process of material distribution, rolling air removal, and heat sealing is smooth. The coordinated operation of each module improves production efficiency, ensures the airtightness of the packaging, reduces the defect rate, and enables continuous packaging operations, providing an efficient and stable solution for towel packaging production.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
