Description

Technical Field

[0001] This utility model relates to an edge sealing mechanism, specifically, to an edge sealing mechanism that adjusts the position of the four edge sealing absorbent pads according to their size. Background Technology

[0002] Absorbent mats for fresh food are everyday items used in the food packaging industry. They are mainly used to absorb blood and juices that seep out of fresh foods such as meat, fruits, and vegetables during storage, transportation, or display. Their core function is achieved through an internal structure of absorbent beads and a water-locking film, which effectively prevents liquid from spilling out. When using them, simply place the mat at the bottom of the food tray and seal it with cling film. During the production of absorbent mats, the absorbent material is sealed with fabric. The fabric is mainly made of non-woven fabric and PE film, which has the advantages of being non-toxic, soft, having good thermal adhesion, high tensile strength, excellent elongation, and strong breathability. In the sealing process, the absorbent material is placed one portion at a time between two layers of fabric. Adhesive granules are applied to the side of the fabric between the two layers. Then, the fabric is heat-pressed and sealed using a sealing mold to seal the absorbent material within the fabric.

[0003] However, most existing four-sided sealing devices for absorbent pads use fixed-size sealing molds. The molds heat and squeeze the absorbent pads for sealing. When producing absorbent pads of different sizes and specifications, the machine must be stopped and the entire set of molds must be replaced, adjusted, and calibrated. This process is cumbersome, time-consuming, and labor-intensive. At the same time, the absorbent pads need to be stationary when the molds heat and squeeze them for sealing, which leads to a decrease in sealing efficiency. In addition, some devices use heating rollers to heat and squeeze the sides of the absorbent pads for sealing. However, this method mostly uses heating coils for heating. The heat conduction efficiency of heating coils is low, and it takes a long time to heat the rubber particles on the sides of the absorbent pads. The moving speed of the absorbent pads needs to be slowed down to ensure the heating effect of the heating coils on the rubber particles, making it difficult to improve the sealing efficiency of the absorbent pads. In view of this, we propose a sealing mechanism that adjusts the position according to the size of the four-sided sealing absorbent pad. Utility Model Content

[0004] The purpose of this invention is to provide a sealing mechanism that adjusts the position of the sealing pad according to the size of the four-sided absorbent pad, so as to solve the problems of continuous operation and low sealing efficiency of the existing absorbent pad sealing device mentioned in the background art.

[0005] To address the aforementioned problems, the present invention aims to provide a sealing mechanism that adjusts the position of a four-sided absorbent pad according to its size. The mechanism includes a base, with a first support frame and a second support frame fixedly connected to its upper side. The first support frame has first mounting grooves on both sides of its top, and the second support frame has second mounting grooves on both sides of its top. A heating component is provided on the upper side of the base to heat the adhesive particles inside the sides of the absorbent pad. The first support frame has a left and right sealing mechanism inside, used to seal the left and right sides of the absorbent pad. The second support frame has a front and rear sealing mechanism inside, used to seal the front and rear sides of the absorbent pad. The left and right sealing mechanisms are located between the heating component and the front and rear sealing mechanisms.

[0006] As a further improvement to this technical solution, the heating assembly includes a mounting bracket fixedly connected to the upper side of the base. A microwave generator is fixedly connected inside the mounting bracket by bolts, and a microwave transmitter is fixedly connected to the upper side of the mounting bracket. The microwave generator and the microwave transmitter are connected together by wires.

[0007] As a further improvement to this technical solution, the left and right sealing mechanism includes a first mounting block that is slidably connected inside the first mounting groove, and an upper printing roller is rotatably connected between the two first mounting blocks.

[0008] As a further improvement to this technical solution, a first fixing block is fixedly connected inside the first mounting groove at a position below the first mounting block, and a lower support roller is rotatably connected between the two first fixing blocks, with the upper printing roller and the lower support roller rotating in opposite directions.

[0009] As a further improvement to this technical solution, a first hydraulic rod is fixedly connected to both sides of the top of the first support frame. The piston rod of the first hydraulic rod passes through the top of the first support frame and is fixedly connected to the upper side of the first mounting block. During the extension and retraction process, the piston rod of the first hydraulic rod drives the first mounting block to move in the vertical direction.

[0010] As a further improvement to this technical solution, the front and rear sealing mechanism includes a second mounting block slidably connected inside the second mounting groove. A rotating roller is rotatably connected to one side of the two second mounting blocks that are close to each other via a rotating rod. A printing ring is fixedly connected to the circumferential surface of the rotating roller. An adjustment component is provided on the second mounting block, and the adjustment component is used to drive the rotating roller to move.

[0011] As a further improvement to this technical solution, a second fixing block is fixedly connected inside the second mounting groove at a position below the second mounting block, and a pressure roller is rotatably connected between the two second fixing blocks. The pressure roller is used to guide the movement of the water-absorbing pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This edge-sealing mechanism, which adjusts its position according to the size of the four-sided absorbent pad, heats the front, back, left, and right sides of the absorbent pad by emitting microwaves through a microwave generator and microwave transmitter during the edge-sealing process. This softens the adhesive particles inside the sides of the absorbent pad. Subsequently, the rotating printing roller, printing ring, and pressure roller squeeze the sides of the absorbent pad, and the softened adhesive particles stick the sides of the absorbent pad together for edge sealing. This improves the continuous operation efficiency and edge-sealing effect of the absorbent pad sides. At the same time, the first and second hydraulic rods drive the rotating roller and heating coil to move, so that the heating coil corresponds to the front and back sides of the absorbent pad, thus making it suitable for absorbent pads of different sizes.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figure 1 - Figure 3 As shown, the purpose of this embodiment is to provide a sealing mechanism that adjusts the corresponding position according to the size of the four-sided absorbent pad. It includes a base 1, a first support frame 11 and a second support frame 12 fixedly connected to the upper side of the base 1. The first support frame 11 has a first mounting groove 111 on both sides of the top of the first support frame 11, and the second support frame 12 has a second mounting groove 121 on both sides of the top of the second support frame 12. A heating component is provided on the upper side of the base 1. The heating component is used to heat the adhesive particles inside the side of the absorbent pad. The first support frame 11 has a left and right sealing mechanism 2 inside. The left and right sealing mechanism 2 is used to seal the left and right sides of the absorbent pad. The second support frame 12 has a front and rear sealing mechanism 3 inside. The front and rear sealing mechanism 3 is used to seal the front and rear sides of the absorbent pad. The left and right sealing mechanism 2 is located between the heating component and the front and rear sealing mechanism 3.

[0030] The heating assembly includes a mounting bracket 13 fixedly connected to the upper side of the base 1. A microwave generator 131, which can be a QC1526 model, is fixedly connected to the inside of the mounting bracket 13 by bolts. A microwave transmitter 132 is fixedly connected to the upper side of the mounting bracket 13. The microwave generator 131 and the microwave transmitter 132 are connected together by wires. During the sealing process of the absorbent pad, the microwave generator 131 is activated, and the microwave transmitter 132 emits microwaves towards the absorbent pad to heat it, causing the adhesive particles inside the absorbent pad to soften. Subsequently, the sides of the absorbent pad are squeezed by the left and right sealing mechanisms 2 and the front and rear sealing mechanisms 3 in sequence, so that the sides of the absorbent pad are glued together by the softened adhesive particles to complete the sealing. In order to avoid the electrical connection terminal at the bottom of the microwave transmitter 132 getting too hot, which would reduce its connection stability and service life under high temperature, a small fan can be installed on one side of the microwave transmitter 132 on the mounting bracket 13. The small fan blows air to the electrical connection terminal of the microwave transmitter 132 to accelerate the air flow on its outside, so that the air carries away the heat and improves the heat dissipation effect.

[0031] refer to Figure 4 and Figure 5 The left and right sealing mechanism 2 includes a first mounting block 21 slidably connected inside the first mounting groove 111, an upper printing roller 22 rotatably connected between the two first mounting blocks 21, a first fixing block 23 fixedly connected inside the first mounting groove 111 at a position below the first mounting block 21, a lower support roller 24 rotatably connected between the two first fixing blocks 23, a first motor 25 fixedly connected to one side of the first mounting block 21 and the first fixing block 23 by a fixing frame, the output shafts of the two first motors 25 drive the upper printing roller 22 and the lower support roller 24 to rotate respectively through a reducer, the upper printing roller 22 and the lower support roller 24 rotate in opposite directions, the circumferential surface of the upper printing roller 22 is provided with a groove, the groove corresponds to the position of the water-absorbing material in the water-absorbing pad, to avoid the upper printing roller 22 and the lower support roller 24 squeezing the water-absorbing material during rotation and causing damage;

[0032] First hydraulic rods 26 are fixedly connected to both sides of the top of the first support frame 11. The piston rod of the first hydraulic rod 26 passes through the top of the first support frame 11 and is fixedly connected to the upper side of the first mounting block 21. During the extension and retraction process, the piston rod of the first hydraulic rod 26 drives the first mounting block 21 to move in the vertical direction to adjust the gap between the upper printing roller 22 and the lower support roller 24, so as to facilitate the staff to pick up and put down the absorbent pad.

[0033] refer to Figure 6 - Figure 8The front and rear sealing mechanism 3 includes a second mounting block 31 slidably connected inside the second mounting groove 121. The two second mounting blocks 31 are rotatably connected to a rotating roller 311 on the side close to each other via a rotating rod 317. One of the rotating rollers 311 is fixedly connected to a support rod on the side away from the second mounting block 31. The other rotating roller 311 has a slot on the right side away from the second mounting block 31. The support rod is slidably inserted into the slot. The two rotating rollers 311 are connected together and supported by the support rod to prevent the rotating roller 311 from tilting away from the second mounting block 31 and causing inconvenience to its normal use. A printing ring 312 is fixedly connected to the circumferential surface of the rotating roller 311. An adjustment component is provided on the second mounting block 31. The adjustment component is used to drive the rotating roller 311 to move.

[0034] Inside the second mounting groove 121, below the second mounting block 31, a second fixing block 313 is fixedly connected. A lower pressure roller 314 is fixedly and rotatably connected between the two second fixing blocks 313. On one side of one of the second fixing blocks 313 away from the lower pressure roller 314, a second motor 315 that drives the lower pressure roller 314 to rotate is fixedly connected via a connecting frame. The output shaft of the second motor 315 drives the lower pressure roller 314 to rotate via a reducer. The rotating lower pressure roller 314 is used to guide the movement of the absorbent pad. The size and rotation speed of the lower pressure roller 314 and the lower support roller 24 are matched, so that the lower pressure roller 314 and the lower support roller 24 drive the absorbent pad to move at the same speed. Similarly, to prevent slippage of the absorbent pad during movement due to the difference in linear speed between the lower pressure roller 314 and the lower support roller 24, and to ensure that the absorbent pad can move normally, the absorbent pad is passed through the gap between the rotating roller 311 and the lower pressure roller 314, so that the adjusting component drives the rotating roller 311 to move downward. The moving rotating roller 311 presses the front and rear sides of the absorbent pad onto the lower pressure roller 314, and the printing ring 312 corresponds to the position of the front and rear sides of the absorbent pad. The printing ring 312 presses the front and rear sides of the absorbent pad together to complete the sealing of the front and rear sides of the absorbent pad, so that the absorbent pad can continuously seal the edges, further improving the sealing efficiency of the absorbent pad.

[0035] The adjustment assembly includes a placement frame 32 fixedly connected to the side of the second mounting block 31 away from the rotating roller 311. A mounting plate 321 is slidably connected inside the placement frame 32. A third motor 322 is fixedly connected to the upper side of the mounting plate 321. The output shaft of the third motor 322 drives the rotating rod 317 and the rotating roller 311 to rotate via a reducer. The rotating roller 311 and the lower pressure roller 314 rotate in opposite directions. A third hydraulic rod 323 is fixedly connected to one side of the placement frame 32. The piston rod of the third hydraulic rod 323 is fixedly connected to the upper side of the mounting plate 321 via a U-shaped bracket. Next, during the extension and retraction process, the piston rod of the third hydraulic rod 323 drives the third motor 322 and the rotating roller 311 to move along the axis of the rotating rod 317 via the mounting plate 321. The second hydraulic rod 316 is fixedly connected to the upper side of the second support frame 12. The piston rod of the second hydraulic rod 316 passes through the second support frame 12 and is fixedly connected to the upper side of the second mounting block 31. During the extension and retraction process, the piston rod of the second hydraulic rod 316 drives the second mounting block 31 to move up or down to adjust the distance and height between the two rotating rollers 311, which is suitable for absorbent pads of different sizes.

[0036] When using this device:

[0037] In the initial state, the rotating roller 311 is located away from the lower pressure roller 314, and the upper printing roller 22 is located away from the lower support roller 24. When the absorbent pad needs to be sealed, the worker will pass the absorbent pad through the gap between the upper printing roller 22 and the lower support roller 24 and the gap between the rotating roller 311 and the lower pressure roller 314 in sequence.

[0038] After the absorbent pad has passed through, the piston rod of the first hydraulic rod 26 extends and drives the upper printing roller 22 to move downward, so that the upper printing roller 22 and the lower support roller 24 squeeze the left and right sides of the absorbent pad. Then, the piston rod of the third hydraulic rod 323 extends and retracts, driving the rotating roller 311 to move, so that the printing ring 312 corresponds to the front and rear sides of the absorbent pad. The piston rod of the second hydraulic rod 316 extends and drives the rotating roller 311 and the printing ring 312 to move downward, so that they squeeze the front and rear sides of the absorbent pad onto the lower pressure roller 314.

[0039] The output shaft of the first motor 25 rotates and drives the upper printing roller 22 and the lower support roller 24 to rotate in opposite directions through the reducer. The second motor 315 and the third motor 322 drive the rotating roller 311 and the lower pressure roller 314 to rotate in opposite directions, thereby driving the absorbent pad to move.

[0040] At the same time, the staff started the microwave generator 131 and emitted microwaves through the microwave transmitter 132 to heat and soften the adhesive particles inside the side of the absorbent pad. The upper printing roller 22 and the lower support roller 24 squeezed and sealed the left and right sides of the absorbent pad, and the printing ring 312 squeezed and sealed the front and rear sides of the absorbent pad, thus completing the sealing process of the absorbent pad.
