Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric heat-bonding bag making technology, and in particular to a heat-sealing machine for nonwoven fabric heat-bonding bag making. Background Technology

[0002] In the nonwoven bag manufacturing industry, heat lamination technology is a commonly used sealing method.

[0003] Traditional nonwoven heat sealing machines often lack flexibility and adaptability, making it difficult to precisely heat seal nonwoven bags of different thicknesses and sizes. Furthermore, the adjustment process for traditional equipment is cumbersome and complex, reducing production efficiency. Especially when processing nonwoven bags of different specifications, operators need to manually adjust multiple parts, which is not only time-consuming and labor-intensive but may also lead to poor sealing results due to improper operation.

[0004] Therefore, the market urgently needs a heat-sealing machine for nonwoven bags that can automatically adapt to different specifications of nonwoven bags, is easy to adjust, and has a good heat-sealing effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing nonwoven heat sealing machines, which often lack flexibility and adaptability and are difficult to perform precise heat sealing on nonwoven bags of different thicknesses and sizes. Therefore, this invention proposes a heat sealing machine for nonwoven heat bonding bag making.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat-sealing machine for making non-woven fabric bags includes a processing base. Two symmetrically arranged fixing frames are fixedly connected to one side of the top of the processing base. The same back plate is fixedly connected to one side of the two fixing frames. A fixed top plate is fixedly connected to one side of the back plate. A heat-sealing assembly for sealing non-woven fabric bags is provided below the fixed top plate.

[0008] The processing base has two symmetrically arranged sliding grooves on its top. Sliders are slidably connected inside the sliding grooves. The same second pressure plate is fixedly connected to one side of the two sliders. A lower support block is fixedly connected to one side of the second pressure plate. The same set of adjustment components for adjusting the position of the second pressure plate is provided between the two sliders.

[0009] In one possible design, the heat-sealing assembly includes two symmetrically arranged fixed sleeves fixedly connected inside a fixed top plate. A sliding rod slides through the interior of each fixed sleeve. The bottom of the two sliding rods is fixedly connected to the same sliding top plate. An electric push rod is fixedly connected to the top of the fixed top plate, and the piston rod of the electric push rod is fixedly connected to the top of the sliding top plate.

[0010] In one possible design, round rods slide through each of the four corners of the sliding top plate. Limiting blocks are fixedly connected to the top of the round rods. The bottom of the four round rods is fixedly connected to the same mounting top plate. Four first springs are fixedly connected between the top of the mounting top plate and the bottom of the sliding top plate. The four first springs are respectively sleeved on the four round rods. A hot press plate is fixedly connected to the bottom of the mounting top plate. A first pressure plate is fixedly connected to one side of the hot press plate.

[0011] In one possible design, the adjustment assembly includes a sliding rod that passes through the interior of the slider. The tops of the two rods are fixedly connected to the same adjustment plate. The bottom of the adjustment plate and the top of the slider are fixedly connected to the same tension spring, which is sleeved on the rod. The bottom inner wall of the groove has multiple slots that engage with the slider.

[0012] In one possible design, the bottom of the adjusting plate is slidably connected to two symmetrically arranged vertical plates, and the two vertical plates are fixedly connected to the same second spring.

[0013] In one possible design, two symmetrically arranged strip plates are fixedly connected to one side of the second pressure plate, and a strip groove is opened on one side of the strip plate. A rectangular block is fixedly connected to one side of the vertical plate, and the rectangular block cooperates with the strip groove.

[0014] In one possible design, support legs are fixedly connected to the four bottom corners of the processing base.

[0015] In one possible design, a dustproof plate is fixedly connected to one side of the fixed top plate.

[0016] In this application, during use, the non-woven bag is placed on the lower support block and the second pressure plate. At this time, the electric push rod is activated. The piston rod of the electric push rod drives the sliding top plate to move down. The sliding top plate drives the mounting top plate to move down. The mounting top plate drives the first pressure plate and the hot pressure plate to move down. The first pressure plate first contacts the lower support block and then presses the non-woven bag. The hot pressure plate then contacts the top of the second pressure plate to achieve the sealing effect of the non-woven bag.

[0017] When the hot press plate and the mounting plate can no longer move down, the sliding plate will squeeze the first spring as it moves down. The sliding plate slides on the round rod to ensure the heat sealing effect. At the same time, the sliding plate as a whole drives the sliding rod to move down. The sliding rod moves inside the fixed sleeve to ensure the stability of the sliding plate's movement.

[0018] When the position of the second pressure plate and the lower support block needs to be adjusted according to the fabric thickness, first press the two vertical plates from the left and right sides. The two vertical plates approach each other and squeeze the second spring. At this time, the vertical plates drive the rectangular block to move laterally. The rectangular block moves out of the inside of the strip groove. At this time, the braking state of the adjusting horizontal plate is released. Then, pull the adjusting horizontal plate vertically upward. At this time, the adjusting horizontal plate drives the two insert rods to move upward. The insert rods move out of the inside of the fixing frame. At this time, the braking state of the slider can be released, and the position of the slider can be adjusted to complete the adjustment of the position of the second pressure plate. At this time, the two springs move upward and move out of the inside. At this time, the braking state of the springs can be released, and the position can be adjusted to complete the position adjustment.

[0019] Beneficial effects: Strong automatic adaptability: Through the synergistic action of the heat sealing component and the adjustment component, this heat sealing machine can automatically adapt to non-woven bags of different thicknesses and sizes. By adjusting the position of the slider, the distance between the second pressure plate and the lower support block can be easily changed, thereby ensuring that the heat pressure plate can accurately seal the non-woven bag, improving the versatility and flexibility of the equipment.

[0020] Easy to operate: The design of the adjustment components allows operators to easily adjust the slider position without complicated procedures. Simply press the vertical plate to release the brake on the horizontal adjustment plate, then pull the horizontal adjustment plate to adjust the slider position, greatly simplifying the operation and improving work efficiency.

[0021] Excellent heat-sealing effect: In the heat-sealing assembly, the heat-pressing plate contacts the second pressure plate after the first pressure plate presses the non-woven bag, achieving a sealing effect on the non-woven bag. Simultaneously, the design of the sliding top plate sliding on the round rod and compressing the first spring ensures stability and uniformity during the heat-sealing process, avoiding poor sealing caused by excessive or insufficient pressure.

[0022] Stable Structure: The overall structure of the equipment is rationally designed. The coordinated use of components such as the fixed sleeve, sliding rod, and round rod ensures the stability and accuracy of the heat-sealing assembly during movement. Meanwhile, the dustproof plate design effectively protects the heat-sealing assembly from dust and debris, extending the equipment's service life.

[0023] Easy to maintain: The components of this heat sealing machine are designed with simplicity in mind, making them easy to disassemble and clean. This greatly reduces equipment maintenance costs and time, and improves the reliability and durability of the equipment. Attached Figure Description
