Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material forming equipment, specifically a dual-station forming machine. Background Technology

[0002] With the development of the times, the application of packaging materials is becoming more and more widespread. Pearl cotton, as an ideal substitute for traditional packaging materials, is widely used in the packaging of mobile phones, instruments, hardware lighting fixtures, and handicrafts to protect products from damage during transportation.

[0003] Packaging materials typically require bonding two layers together during processing. Currently, the common practice is to partially heat and melt one layer of material using a hot plate before bonding it to the unheated layer. This bonding process, which only heat-treats one layer while leaving the other untreated, requires a greater depth and time for heat treatment, severely impacting the bonding quality and effectiveness. Furthermore, existing molding machines, in an effort to reduce costs and size, often only have one feeding mechanism, resulting in low processing efficiency and hindering mass production. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a dual-station forming machine, including a machine body, a material gripping mechanism fixedly mounted on the machine body, and a feeding mechanism and a heating plate mechanism movably mounted below the material gripping mechanism.

[0005] There are at least two feeding mechanisms, and the two feeding mechanisms move alternately downwards towards the gripping mechanism. The feeding mechanism includes a transverse base, a first lifting component disposed on the transverse base, and a feeding plate disposed on the first lifting component. The feeding plate rises under the drive of the first lifting component and contacts the gripping mechanism, so that the gripping mechanism grips the upper material on the feeding plate.

[0006] The heating plate mechanism is located between the material gripping mechanism and the feeding mechanism. The heating plate mechanism includes a horizontal conveying component, a second lifting component, and a heating plate. The heating plate moves downwards from the material gripping mechanism under the drive of the horizontal conveying component and contacts the upper material on the material gripping mechanism or the lower material on the feeding plate under the drive of the second lifting component.

[0007] Furthermore, at least two feeding mechanisms are located at the same position on the machine body, and the feeding mechanisms are arranged vertically and alternately move downwards towards the gripping mechanism.

[0008] Furthermore, there are two feeding mechanisms: an upper feeding mechanism and a lower feeding mechanism. During feeding, the upper feeding mechanism moves horizontally above the lower feeding mechanism, or the lower feeding mechanism moves horizontally below the upper feeding mechanism. When the feeding plate of the upper feeding mechanism or the feeding plate of the lower feeding mechanism is below the gripping mechanism, it rises under the drive of the first lifting component and contacts the gripping mechanism, which then grips the upper material on the feeding plate.

[0009] Furthermore, the first lifting assembly includes a nut seat rotatably mounted on the transverse base, a screw threaded to the nut seat, and a first driving assembly for driving the nut seat to rotate; the lower end of the screw thread passes through the transverse base and extends downward, and the upper end of the screw thread is connected to the feeding plate.

[0010] Furthermore, the horizontal conveying component is a belt conveyor component, and two are arranged in parallel intervals. Each of the two belt conveyor components is equipped with a second lifting component, and the heating plate is arranged at the lifting end of the two second lifting components.

[0011] Furthermore, the two second lifting components move up and down on opposite sides of the material gripping mechanism.

[0012] Furthermore, the belt conveyor assembly includes a conveyor belt, a limiting block fixed on the conveyor belt, and a slide plate fixedly connected to the limiting block. Horizontal sliders are fixed vertically at intervals on one side of the slide plate opposite to the conveyor belt. A corresponding horizontal slide rail matching the horizontal sliders is provided on the machine body. The second lifting assembly is set on the slide plate.

[0013] Furthermore, the second lifting assembly includes a nut block fixed on the side of the slide away from the conveyor belt, a lead screw threadedly connected to the nut block, and a lifting block rotatably connected to the upper end of the lead screw; the lifting block is fixed on the lifting plate, the upper end of the lifting plate is fixed with a first driving assembly for driving the lead screw to rotate, and the lower end of the lifting plate is fixedly connected to the heating plate.

[0014] Furthermore, the heating plate is a double-sided heating plate. After the material gripping mechanism grips the material, the heating plate moves between the material gripping mechanism and the feeding plate and comes into contact with the upper material or the lower material.

[0015] Furthermore, the feeding mechanism and the hot plate mechanism are located on opposite sides of the gripping mechanism, and both move horizontally along the length of the machine body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This application achieves uninterrupted processing of the bonding machine by setting up multiple alternating feeding mechanisms, greatly improving the production efficiency of packaging products. At the same time, by setting the feeding plate and the heating plate to be height-adjustable, the vertical distance between the feeding plate and the gripping mechanism, the feeding plate and the heating plate, and the heating plate and the gripping mechanism can all be adjusted. This allows for heating the upper layer material while preheating the lower layer material, or heating the lower layer material while preheating the upper layer material. This not only shortens the heat-melting time but also reduces the thickness of the material being melted, saving materials while improving the bonding quality of the packaging materials.

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be described in detail with specific embodiments.

[0027] like Figure 1-5As shown, this utility model provides a dual-station forming machine for bonding upper and lower layers of materials. The materials to be processed are not limited to packaging materials such as pearl cotton and foam cotton. The dual-station forming machine includes a machine body 1, on which a material gripping mechanism 2 is fixedly installed. A feeding mechanism and a heating plate mechanism 5 are movably installed below the material gripping mechanism 2. In this application, the material gripping mechanism 2 is set as a fixed structure, and the material gripping is achieved by the movement of the feeding mechanism. That is, only one mechanism needs to move to complete the material gripping process, which simplifies the material gripping control procedure. There are at least two feeding mechanisms, and at least two feeding mechanisms move alternately below the material gripping mechanism 2 to achieve uninterrupted feeding and processing, thereby improving the processing efficiency of the equipment. The feeding mechanism includes a transverse base 31, a first lifting component 32 set on the transverse base 31, and a feeding plate 33 set on the first lifting component 32. The feeding plate 33 rises under the drive of the first lifting component 32 and contacts the material gripping mechanism 2, so that the material gripping mechanism... 2. The upper material 6 on the feeding plate 33 is gripped. After the gripping mechanism 2 grips the upper material 6, the first lifting component 32 drives the feeding plate 33 to descend, separating the upper material 6 and the lower material 7. In the non-working state, the heating plate mechanism 5 is away from the gripping mechanism 2 and the feeding mechanism. The heating plate mechanism 5 includes a horizontal conveying component 51, a second lifting component 52 and a heating plate 53. The heating plate 53 moves downward of the gripping mechanism 2 under the drive of the horizontal conveying component 51, and contacts the upper material 6 on the gripping mechanism 2 or the lower material 7 on the feeding plate 33 under the drive of the second lifting component 52. It can be understood that all structures of the heating plate 53 on the heating plate mechanism 5 that can realize lifting and horizontal movement are within the protection scope of this application. In the specific embodiment of this application, the horizontal conveying component 51 is set on the machine body 1, the second lifting component 52 is set on the horizontal conveying component 51, and the heating plate 53 is set on the second lifting component 52 as an example for explanation.

[0028] This application incorporates multiple alternating feeding mechanisms, enabling intermittent processing of the bonding machine and improving the production efficiency of packaging materials. Simultaneously, the gripping mechanism 2 is designed as a fixed structure, while the feeding mechanism and heating mechanism 5 are designed to move both horizontally and vertically. This allows for adjustable vertical distances between the feeding plate 33 and the heating plate 53, as well as between the heating plate 53 and the gripping mechanism 2. This enables the processing of materials with different packaging requirements, such as heat-melting the upper layer material 6 or the lower layer material 7. Furthermore, adjusting the relative vertical distances allows for preheating of materials that have not yet been heat-melted. Notably, when bonding two layers of material, preheating one layer can appropriately reduce the heat-melting time and thickness of the other layer, thereby saving materials while improving the bonding quality of the packaging materials.

[0029] Specifically, at least two feeding mechanisms are located on the same side of the machine body 1, and the feeding mechanisms are arranged vertically and move alternately downwards towards the gripping mechanism 2. Arranging the feeding mechanism 2 vertically can reduce the overall size of the molding machine, making it more compact. Furthermore, having the feeding mechanisms in the same position on the machine body 1 allows for single-person operation, reducing labor costs.

[0030] Specifically, such as Figure 2 As shown, in some embodiments, there are two feeding mechanisms: an upper feeding mechanism 3 and a lower feeding mechanism 4. During feeding, the upper feeding mechanism 3 moves horizontally above the lower feeding mechanism 4. When it moves below the gripping mechanism 2, the feeding plate 33 of the upper feeding mechanism 3 moves upward under the drive of the first lifting component 32 and contacts the gripping mechanism 2. The gripping mechanism 2 then grips the upper material 6 on the upper feeding mechanism 3. Alternatively, the lower feeding mechanism 4 moves horizontally below the upper feeding mechanism 3. When it moves below the gripping mechanism 2, the feeding plate 33 of the lower feeding mechanism 4 moves upward under the drive of the first lifting component 32 and contacts the gripping mechanism 2. The gripping mechanism 2 then grips the upper material 6 on the lower feeding mechanism 4.

[0031] Specifically, the first lifting assembly 32 includes a nut seat 321 rotatably mounted on the transverse base 31, a screw 322 screwed to the nut seat 321, and a first driving assembly 323 that drives the nut seat 321 to rotate; the lower end of the screw 322 passes through the transverse base 31 and extends downward, and the upper end of the screw 322 is connected to the feeding plate 33.

[0032] Specifically, a guide cylinder 324 is fixed to the upper surface of the transverse base 31. A guide post 325 is provided inside the guide cylinder 324. The lower end of the guide post 325 extends downwards after passing through the transverse base 31, and the upper end of the guide post 325 is fixedly connected to the feeding plate 33. It should be noted that, because the feeding mechanisms in this application are arranged vertically, the feeding mechanism located above must provide clearance space for the feeding mechanism below it, making the overall structure of the molding machine more compact. Optionally, the transverse base 31 of the first feeding mechanism 3 can be designed as two spaced-apart transverse plates. Each transverse plate is equipped with a first lifting assembly 32. The second feeding mechanism 4 is movably positioned between the two transverse plates, and the size of the feeding plate of the second feeding mechanism 4 is smaller than the size of the feeding plate of the first feeding mechanism 3. Since this embodiment only has two feeding mechanisms, the second feeding mechanism 4 does not need clearance space; therefore, the transverse base 31 of the second feeding mechanism 4 can be a single transverse plate. It is understandable that if there are three or more feeding mechanisms, in order to achieve a compact structure for the bonding machine, all feeding mechanisms except the bottom one need to have clearance space to facilitate the horizontal movement of the feeding mechanisms below them.

[0033] In some embodiments, the transverse base 31 is laterally movable on the body 1 via a horizontal moving assembly 34. The horizontal moving assembly 34 includes a rack 341 fixed on the body 1, a gear 342 rotatably mounted on the transverse base 31, and a driving member 343 that drives the gear 342 to rotate. The gear 341 meshes with the rack 341 for transmission. The driving member 343 is mounted on the transverse base 31 and drives the gear 342 to rotate. The gear 342 meshes with the rack 341, thereby enabling the transverse base 31 to move laterally along the rack 341.

[0034] Specifically, in some embodiments, such as Figure 3 and Figure 4 As shown, the horizontal conveying component 51 of the heating plate mechanism 5 is a belt conveyor component, and two are arranged in parallel at intervals. Each of the two belt conveyor components has a second lifting component 52, and the heating plate 53 is located at the lifting ends of the two second lifting components 52. The belt conveyor components drive the two second lifting components 52 to move horizontally synchronously, and the two second lifting components 52 drive the two ends of the heating plate 53 to move up and down synchronously, thereby realizing the horizontal and vertical movement of the heating plate 53. The two second lifting components 52 move up and down on opposite sides of the material gripping mechanism 2, that is, the size of the material grabbing plate on the material gripping mechanism 2 is smaller than the size of the heating plate 53, allowing the heating plate 53 to move up and down directly below the material grabbing plate. It is understood that the belt conveyor component is only one embodiment of this application and is not limited thereto. All horizontal conveying components 51 that can realize the horizontal movement of the heating plate 53 without interfering with the material gripping mechanism 2 are within the protection scope of this application.

[0035] The heating plate mechanism 5 and the material gripping mechanism 2 of this application have a reasonable structural design. Through two belt conveyor components and a second lifting component 52 arranged at intervals, the movement of the heating plate 53 and the material gripping mechanism 2 do not interfere with each other, thus cleverly realizing the lifting and lowering of the heating plate 53, thereby realizing the heating and melting of the upper material and the preheating of the lower material, or the preheating of the upper material and the heating and melting of the lower material.

[0036] For details, please refer to Figure 3 The belt conveyor assembly includes a conveyor belt 511, a limiting block 512 fixed on the conveyor belt 511, and a sliding plate 513 fixedly connected to the limiting block 512. Horizontal sliders 514 are fixedly mounted vertically at intervals on one side of the sliding plate 513 opposite to the conveyor belt 511. A corresponding horizontal slide rail 515 matching the horizontal sliders 514 is provided on the machine body 1. A second lifting assembly 52 is mounted on the sliding plate 513. The horizontal sliders 514 and the horizontal slide rail 515 improve the stability and straightness of the movement of the heating plate 53, avoiding unstable transmission caused by a loose conveyor belt 511. (See reference...) Figure 4The two conveyor belts are synchronously transported by a motor 541, a reducer 542, a drive shaft 543, and a synchronous pulley 544. The motor 541 drives the drive shaft 543 to rotate through the reducer 542. The rotation of the drive shaft 543 drives the synchronous pulleys 544 located at both ends of it to rotate. The synchronous pulleys 544 at both ends of the drive shaft 543 have the same diameter, thereby achieving synchronous transport of the two conveyor belts 511 through the synchronous pulleys 544.

[0037] For details, please refer to Figure 3 The second lifting assembly 52 includes a nut block (not shown) fixed to the side of the slide plate 513 facing away from the conveyor belt 511, a lead screw 521 threadedly connected to the nut block, and a lifting block 522 rotatably connected to the upper end of the lead screw 521. The lifting block 522 is fixed on the lifting plate 523, and a first drive assembly 524 for driving the lead screw 521 to rotate is fixed to the upper end of the lifting plate 523. The lower end of the lifting plate 523 is fixedly connected to the heating plate 53. The first drive assembly 524 drives the lead screw 521 to rotate relative to the nut block and move downward or upward, thereby driving the lifting plate 523 to rise and fall. The rising and falling of the lifting plate 523 drives the heating plate 53 to move up and down.

[0038] Specifically, the heating plate 53 is a double-sided heating plate. After the material gripping mechanism 2 grips the material, the heating plate 53 moves between the material gripping mechanism 2 and the feeding plate 33, and moves upward to contact the upper material or downward to contact the lower material. The feeding mechanism and the heating plate mechanism 5 are located on opposite sides of the material gripping mechanism 2, and both move horizontally along the length of the machine body 1.

[0039] In some embodiments, see Figure 5 The material gripping mechanism 2 includes a coupling slide plate 21 fixed on the machine body 1, a vertical support 22 fixedly connected to the coupling slide plate 21, and a material picking component 23 fixed at the lower end of the vertical support 22. The material picking component 23 includes a material picking plate, which can be a needle plate assembly or a negative pressure adsorption material picking plate. The material gripping mechanism 2 of this application belongs to the prior art. Those skilled in the art can refer to the prior art to make the design, and will not be described in detail here.

[0040] The working principle of this utility model is as follows: In the initial position, the upper feeding mechanism 3 and the lower feeding mechanism 4 are located on the same side of the machine body 1. The material to be processed is placed on the upper feeding mechanism 3 by the operator, and the upper feeding mechanism 3 is started, so that the upper feeding mechanism 3 moves horizontally above the lower feeding mechanism 4 towards the gripping mechanism 2. When it moves to directly below the gripping mechanism 4, the first lifting component 32 of the upper feeding mechanism 3 is activated. The first lifting component 32 drives the feeding plate 33 on it to rise and contact the gripping mechanism 2. The gripping mechanism 2 takes away the upper material 6 on the feeding plate 33. After that, the feeding plate 33 drives the lower material on it to move away. Material 7 descends a certain distance and then stops. The heating plate mechanism 5 is activated, and the heating plate 53, driven by the horizontal conveying component 51, moves horizontally towards the material gripping mechanism 2. When it reaches directly below the material gripping mechanism 2, the heating plate 53 rises and contacts the upper material 6 on the material gripping mechanism 2 to melt it, while maintaining a certain preset distance from the lower material 7 on the feeding plate 33 of the upper feeding mechanism 3 to preheat the lower material 7; or the heating plate 53 contacts the lower material 7 on the feeding plate 33 of the upper feeding mechanism 3 to melt it, while maintaining a certain preset distance from the upper material 6 on the material gripping mechanism 2 to preheat the upper material 6. This application can achieve melting one material and preheating another, which not only shortens the melting time but also reduces the melting thickness of the material being melted, saving material and improving bonding quality. Furthermore, the working process of the lower feeding mechanism 4 is the same as that of the upper feeding mechanism 3, and will not be described in detail here.

[0041] It should be noted that this application does not specifically limit the timing of raising and lowering the heating plate 53. It can be raised and lowered first and then moved horizontally, or it can be moved horizontally first and then raised and lowered, both of which are within the scope of protection of this application.

[0042] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
