Description

Technical Field

[0001] The invention belongs to the technical field of packaging material bonding equipment, in particular to a hot plate bonding machine. Background Art

[0002] Hot plate bonding technology is widely used in the splicing of thermoplastic materials such as plastics, rubber, and composite materials (such as pearl cotton (EPE)). It is particularly in demand in packaging, footwear, automotive interiors, and sports equipment. This technology utilizes a heated plate to melt and soften the contacting surfaces of the materials, followed by cooling and bonding under pressure. Traditional hot plate bonding machines typically include basic functional modules such as feeding, conveying, heating (hot plate), retrieving, and discharging. However, existing equipment commonly suffers from the following bottlenecks that hinder efficiency and quality:

[0003] 1. Dispersed layout, large space occupation: Functional mechanisms (such as feeding, heating, retrieving, and discharging) are often arranged in parallel or staggered locations, significantly increasing the overall width of the equipment (perpendicular to the processing direction). This structure is difficult to adapt to the narrow or long working spaces commonly found in modern factories, limiting the equipment's installation flexibility.

[0004] 2. Complex processing lines and limited efficiency: Due to an unreasonable mechanical layout, the material flow path (movement line) between feeding, heating, retrieving, and discharging may be circuitous, intersecting, or excessively long. This not only increases ineffective movement time, but also reduces the equipment's production cycle and overall production efficiency.

[0005] 3. Long waiting times for feeding and retrieving materials: Many machines are equipped with only a single feeding mechanism. After the material carried by this mechanism is heated under the hot platen and removed, it must exit the hot platen area empty before new material can be fed into the heating area. This "exit-entry" process causes intermittent waiting times during production, preventing continuous operation.

[0006] 4. Poor control of heating efficiency and melting depth:

[0007] (1) Limited single-sided heating / preheating: Traditional structural design means that only one side of the material placed on the hot plate can be heated or preheated. If the other side needs to be preheated (such as before bonding), additional workstations or operation steps are often required, significantly extending the overall processing cycle.

[0008] (2) Excessive heating time / excessive melting: In order to ensure bonding strength, a longer heating time is sometimes required, but this can easily lead to a too deep melting layer of the material. Excessive melting not only wastes material, but may also affect the dimensional stability of the bonding area and the aesthetics and mechanical properties of the final product (such as thinning and collapse) due to excessive softening. Accurately controlling the melting depth and shortening the heating time are key difficulties in improving product quality and reducing costs.

[0009] 5. Non-streamlined operation process: The location arrangement of feeding, heating, discharging and other links is unreasonable, failing to form a smooth one-way assembly line operation, increasing the frequency of operator intervention or the complexity of material transfer.

[0010] Therefore, there is an urgent need to develop a new type of hot plate bonding equipment, which should be able to effectively solve problems such as space occupation, production efficiency, heating optimization and process simplification. The specific goals include: achieving compactness of the equipment in the processing direction (narrow and long design), simplifying the material flow line, reducing the waiting time for feeding and unloading materials, supporting flexible and efficient heating / preheating combinations of upper and lower sheets to shorten the cycle and accurately control the melting quality, and ultimately forming an efficient streamlined operation mode.

[0044] The following is combined with Figure 1 To the attached Figure 6 The present invention is described in detail with specific embodiments.

The hot plate bonding machine of the present invention adopts a compact linear layout, such as Figure 1 As shown, the frame 1 is sequentially integrated with a feeding mechanism 6, a material delivery mechanism, an ironing mechanism 5, a material retrieving mechanism 4, and a material discharging conveying mechanism 7 along a first direction (material processing direction).

A retrieving nut 467 is fixed to the side of the slide 41 opposite the lifting plate 44 and is in transmission connection with the retrieving screw 468.

[0048] In some embodiments, the frame 1 is provided with a second transverse rail 13 and a second transverse rack 14 extending in a first direction. The ironing plate mechanism 5 includes a slider slidably connected to the second transverse rail 13, and a hot plate fixedly mounted on the slider. The frame 1 is also provided with a hot plate drive mechanism, wherein a driving shaft of the hot plate drive mechanism is provided with a hot plate mechanism gear that meshes with the second transverse rack 14. Specifically, the hot plate drive mechanism can be a combination of a motor and a reducer, and is not limited to a single form. Any drive mechanism capable of driving the hot plate falls within the scope of protection of this application.

[0049] In some embodiments, there are at least two feeding mechanisms, and the feeding mechanisms can be moved alternately to the bottom of the ironing plate mechanism; the feeding mechanism includes a transverse base and a feeding plate arranged on the transverse base through a lifting assembly; at least two of the feeding mechanisms are arranged in sequence of height along the first direction, and move alternately to the bottom of the material picking mechanism 4; there are two feeding mechanisms, namely the first feeding mechanism 2 and the second feeding mechanism 3; when feeding, the first feeding mechanism 2 moves horizontally above the second feeding mechanism 3, or the second feeding mechanism 3 moves horizontally below the first feeding mechanism 2; when the first feeding mechanism 2 feeds to the processing station, the feeding plate of the first feeding mechanism 2 rises, or when the second feeding mechanism 3 feeds to the processing station, the feeding plate of the second feeding mechanism 3 rises.

[0050] Specifically, the first feeding mechanism 2 includes a first transverse base 21 arranged in parallel and spaced relation, a first lifting assembly 22 mounted on the first transverse base 21, and a first feeding plate 23 fixed to the lifting ends of the two first lifting assemblies 22. The second feeding mechanism 3 is located between the two second transverse bases 31 and includes a second transverse base 31, a second lifting assembly 32, and a second feeding plate 33. The second feeding plate 33 is mounted at the lifting ends of the second lifting assembly 32, and the size of the second feeding plate 33 is smaller than that of the first feeding plate 23. Specifically, the lifting assembly includes a nut seat rotatably mounted on the transverse base, a screw threadedly connected to the nut seat, and a driving assembly for driving the nut seat to rotate. The lower end of the screw passes through the transverse base and extends downward, and the upper end of the screw is connected to the feeding plate. Specifically, a guide cylinder is fixed to the upper surface of the transverse base, and a guide column is disposed within the guide cylinder. The lower end of the guide column passes through the transverse base and extends downward, and the upper end of the guide column is fixedly connected to the feeding plate.

[0051] In some embodiments, the first lifting assembly 22 includes a first nut seat 221 rotatably mounted on a corresponding first transverse base 21, a first screw 222 threadedly connected to the first nut seat 221, and a first drive assembly 223 for driving the first nut seat 221 to rotate, wherein the lower end of the first screw 222 passes through the first transverse base 21 and extends downward, and the upper end of the first screw 222 is connected to the first feed plate 23; the first drive assembly 223 drives the first nut seat 221 to rotate, and the rotation of the first nut seat 221 drives the first screw 222 to move vertically up and down, thereby achieving vertical up and down movement of the first feed plate 23. In this embodiment, the cooperation between the nut seat and the screw is used to achieve the lifting of the first feed plate 23, which has the advantages of high precision and high efficiency. It is understood that all first lifting assemblies 22 that can achieve the lifting function of the first feed plate 23 in this application fall within the scope of protection of this application, and the illustrated first lifting assembly 22 is only one embodiment, but is not limited to this.

[0052] Specifically, in some embodiments of the present application, the first drive assembly 223 includes a first motor 2231, a first driving wheel 2232 mounted on the motor shaft of the first motor 2231, a first driven wheel 2233 fixedly mounted on the lower end of the first nut seat 221, and a first conveyor belt 2234 mounted on the first driving wheel 2232 and the first driven wheel 2233. The first motor 2231 drives the first driving wheel 2232 to rotate, and the first driving wheel 2232 drives the first driven wheel 2233 to rotate via the first conveyor belt 2234. The rotation of the first driven wheel 2233 drives the first nut seat 221 to rotate, thereby driving all the first screw rods 222 to move up and down. It can be understood that the function of the first drive assembly 223 is to drive the first nut seat 221 to rotate. Therefore, the structure of the first drive assembly 223 is not specifically limited. The above is only one embodiment. However, other first drive assemblies 223 that can achieve rotation of the first nut seat 221 also fall within the scope of protection of this application.

[0053] In some embodiments, a first guide cylinder 224 is further fixed to the upper surface of the first transverse base 21. A first guide column 225 is disposed within the first guide cylinder 224. The lower end of the first guide column 225 extends downward after penetrating the first transverse base 21, and the upper end of the first guide column 225 is fixedly connected to the first feed plate 23. Preferably, a first guide cylinder 224 is fixed to the side of each first nut seat 221. The first guide cylinder 224 and the first guide column 225 guide the raising and lowering of the first feed plate 23, thereby preventing the first nut seat 221 from being deflected by force during rotation, which would cause the first feed plate 23 to deflect, ultimately affecting the horizontality of the upper end surface of the first feed plate 23 and indirectly affecting the bonding quality.

[0054] In some embodiments, the second lifting assembly 32 includes a second nut seat 321 rotatably mounted on a corresponding second transverse base 31, a second screw 322 threadedly connected to the second nut seat 321, and a second drive assembly 323 for driving the second nut seat 321 to rotate. The lower end of the second screw 322 extends downward through the second transverse base 31, and the upper end of the second screw 322 is connected to the second feed plate 33. The second drive assembly 323 drives the second nut seat 321 to rotate. The rotation of the second nut seat 321 drives the second screw 322 to move vertically up and down, thereby achieving vertical up and down movement of the second feed plate 33. In this embodiment, the cooperation between the nut seat and the screw is used to achieve the lifting of the second feed plate 33, which has the advantages of high precision and high efficiency. It is understood that all second lifting assemblies 32 that can achieve the lifting function of the second feed plate 33 in this application fall within the scope of protection of this application, and the second lifting assembly 32 shown in the figure is only one embodiment, but is not limited to this.

[0055] Specifically, the second drive assembly 32 in the embodiment of the present application includes a second motor 3231, a second driving wheel 3232 mounted on the motor shaft of the second motor 3231, a second driven wheel 3233 fixedly mounted on the lower end of the second nut seat 321, and a second conveyor belt 3234 mounted on the second driving wheel 3232 and the second driven wheel 3233. The second motor 3231 drives the second driving wheel 3232 to rotate, and the second driving wheel 3232 drives the second driven wheel 3233 to rotate via the second conveyor belt 3234. The rotation of the second driven wheel 3233 drives the second nut seat 321 to rotate, thereby driving all the second screw rods 322 to move up and down. It can be understood that the function of the second drive assembly 323 is to drive the second nut seat 321 to rotate. Therefore, the structure of the second drive assembly 323 is not specifically limited. The above is only one embodiment. However, other second drive assemblies 323 that can achieve the rotation of the second nut seat 321 also fall within the scope of protection of this application.

[0056] Specifically, in some embodiments, a plurality of second guide cylinders 324 are further fixed to the upper surface of the second transverse base 31. Second guide posts 325 are disposed within the second guide cylinders 324. The lower ends of the second guide posts 325 extend downwardly through the second transverse base 31, and the upper ends of the second guide posts 325 are fixedly connected to the second feed plate 33. Preferably, a second guide cylinder 324 is fixed to the side of each second nut seat 321. The second guide cylinders 324 and the second guide posts 325 guide the raising and lowering of the second feed plate 33, thereby preventing the second nut seat 321 from being deflected by force during rotation, which would cause the second feed plate 33 to deflect, ultimately affecting the horizontality of the upper end surface of the second feed plate 33 and indirectly affecting the bonding quality.

[0057] The feed mechanism consists of two independent units (a first feed mechanism 2 and a second feed mechanism 3), arranged in a staggered arrangement along a first direction. The first feed mechanism 2 is located at the upper position and comprises two parallel sets of first transverse bases 21, connected to a large first feed plate 23 via a first lifting assembly 22. The second feed mechanism 3 is located at the lower position and utilizes a single transverse base in conjunction with a smaller second feed plate 33. The two mechanisms are alternately moved directly below the hot plate mechanism 5 via the transverse bases. The lifting assembly rotates the nut seat to drive the screw, which in turn drives the feed plate vertically. Guide cylinders and guide posts ensure stability. When the first feed mechanism 2 enters the processing position, its feed plate rises to contact the hot plate. The second feed mechanism 3 simultaneously prepares at the standby position, achieving seamless alternating feeding.

[0058] In some embodiments, the feeding mechanism 6 includes a feeding platform 61, with a lifting mechanism 62 provided on opposite sides of the feeding platform 61. The lifting mechanisms 62 can move the feeding platform 61 up and down. The lifting mechanisms 62 on both sides of the feeding platform 61 drive the feeding platform 61 to a material removal height. After feeding is completed, the platform returns to the storage position, realizing automatic material refilling.

[0059] In some specific embodiments, the lifting mechanism 62 of the present application includes a bearing fixing plate 622, a motor fixing frame 623, and a feeding motor 624 arranged on the motor fixing frame 623. The motor fixing frame 623 is arranged on the bearing fixing plate 622. The output shaft of the feeding motor 624 is connected to a feeding reducer 625. The output shaft of the feeding reducer 625 is connected to a first synchronous wheel 626. Two idler wheels 627 are provided on the bearing fixing plate 622 for rotation near the first synchronous wheel 626, and two idler wheels 627 are provided for rotation away from the first synchronous wheel 626. The first synchronous wheel 626, the two idler wheels 627, and the two second synchronous wheels 628 are each provided with an annular synchronous belt 621. The two second synchronous wheels 628 are rotatably connected to a feed screw 629, which is provided with a feed nut 630. The feed platform 61 is fixedly connected to the two feed nuts 630. Specifically, the feed nuts are T-nuts. The rotation of the feed screw 629 drives the feed nuts 630 up and down, thereby driving the feed platform 61 up and down, achieving the lifting function of the feed platform 61. To ensure stable rotation of the feed screw 629, both ends of the feed screw 629 are connected to corresponding bearing fixing plates via bearings.

[0060] In some embodiments, the ironing mechanism 5 includes a double-sided ironing plate that moves between the reclaiming plate and the feed plate, contacting the material on either the reclaiming plate or the feed plate. The ironing mechanism 5 is slidably connected to the second transverse rail 13 of the frame 1 via a slider. The double-sided ironing plate is fixed to the slider. The ironing mechanism motor, driven by a speed reducer, engages the ironing mechanism gears, which engage the second transverse rack 14, for fine-tuning the horizontal position. This ironing plate can simultaneously contact the material on the reclaiming plate above and the feed plate below, supporting simultaneous heating or preheating of both sides.

[0061] In some embodiments, the discharge conveying mechanism 7 includes a conveying belt and a belt driving assembly, and the belt driving assembly drives the conveying belt to move, thereby moving the processed finished products outward.

[0062] The workflow of the present invention is as follows:

[0063] The feeding mechanism 6 raises the material to the retrieving height. The retrieving mechanism 4 moves to the feeding position, grabs the upper sheet, and then moves horizontally above the hot plate mechanism 5. Simultaneously, the first feeding mechanism 2 feeds the lower sheet under the hot plate. The retrieving plate descends, allowing the upper sheet to contact the upper surface of the hot plate for preheating. The first feeding plate 23 ascends, allowing the lower sheet to contact the lower surface of the hot plate for heating. After melting is complete, the hot plate is removed, and the retrieving plate presses down to achieve bonding. The retrieving mechanism 4 then carries the finished product to the discharge conveyor mechanism 7. Simultaneously, the second feeding mechanism 3 enters the processing position to pick up a new lower sheet. The first feeding mechanism 2 exits and loads the next material, forming a continuous cycle.

[0064] The hot plate bonding machine of the present application has limited width and is suitable for narrow and long spaces. At the same time, it simplifies the material processing line and greatly improves the material production efficiency; by arranging the feeding mechanism and the discharging conveying mechanism 7 at the head and tail of the material processing direction, the streamlined operation of the processed materials is realized; the material picking plate and the feeding plate are arranged into a liftable structure, and are respectively located on both sides of the ironing plate mechanism 5, so that the vertical distance between the material picking plate and the feeding plate and the ironing plate mechanism 5 can be adjusted, so that they can reach the upper and lower parts of the ironing plate mechanism 5 respectively in the shortest time, and can realize heating the lower piece and preheating the upper piece, or heating the upper piece and preheating the lower piece, so as to shorten the heating, melting and softening time of the pearl cotton and reduce the melting depth, save material, and improve the bonding quality of the material.

[0065] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
