Description

Technical Field

[0001] The invention belongs to the technical field of sealing machines, and in particular relates to a rapid prototyping sealing machine. Background Art

[0002] In industrial production, after packaging products with packaging bags, a sealing machine is needed to seal the opening of the packaging bag. A heat sealer is a device that melts and presses the edges of packaging materials (usually plastic films or composite materials) together by heating to form a sealing effect. When using a traditional heat sealer, workers need to manually place the open end of the packaging bag on a heating plate, and then use an extrusion plate to squeeze the open end of the packaging bag toward the heating plate to seal the packaging bag. During the operation, the worker's hands are close to the heating plate and are easily burned by the heating plate, which poses a great safety hazard. Therefore, the traditional sealing machine needs to be improved. Summary of the invention

[0003] The purpose of the present invention is to provide a rapid prototyping sealing machine in view of the above-mentioned technical problems, which can separate workers from the heating plate when placing and clamping packaging bags, thereby reducing the safety hazards during the operation of the sealing machine.

[0004] In view of this, the present invention provides a rapid prototyping sealing machine, comprising:

[0005] A workbench is provided on the workbench, the surface of the heating plate can be heated, a movable extrusion plate is provided above the heating plate, a material placement space is formed between the heating plate and the extrusion plate, and the extrusion plate can be close to and away from the heating plate;

[0006] The heat insulation board is arranged between the heating board and the extrusion board, and the heat insulation board can move horizontally on the workbench, and the heat insulation board can cover the heating board and open the heating board on the moving track;

[0007] The clamping piece can clamp and release the object to be sealed located in the material placement space.

[0008] In the present technical solution, before sealing the packaging bag, the heating plate is started for preheating, the extrusion plate is moved away from the heating plate, and the insulation plate is moved to cover the heating plate. At this time, the worker puts the open end of the packaging bag into the material storage space and places it on the insulation plate, and clamps the end of the packaging bag with a clamp. Then the worker moves away from the heating plate and moves the insulation plate to open the heating plate. At this time, the open end of the packaging bag comes onto the heating plate, and the extrusion plate is pushed toward the heating plate so that the extrusion plate and the heating plate cooperate to seal the open end of the packaging bag. After sealing is completed, the extrusion plate is moved away from the heating plate, the packaging bag is released by the clamp, and the insulation plate is moved to cover the heating plate. At this time, the worker removes the packaging bag from the workbench, and the sealing of a packaging bag is completed.

[0009] In the above technical solution, further, a swing frame is provided on the workbench, one end of the swing frame is hinged to the workbench, and the other end of the swing frame is connected to the extrusion plate.

[0010] In the above technical solution, further, the swinging of the swing frame relative to the workbench is driven manually or electrically.

[0011] In the above technical solution, further, a sliding seat is provided at one end of the insulation board, the sliding seat is horizontally slidable on the workbench, a first cylinder is provided under the workbench, the sliding seat and the output end of the first cylinder are connected by a first connecting rope, a fixed seat is provided on the workbench, and a linear elastic member is connected between the fixed seat and the sliding seat.

[0012] In the above technical scheme, further, a clamping seat is provided on the workbench and on both sides of the heating plate, and a swing clamp is provided on the two clamping seats. One end of the two swing clamps are rotatably connected to the two clamping seats respectively, and the bottom surfaces of the other ends of the two swing clamps can cooperate with the upper surface of the insulation plate to clamp the two ends of the object to be sealed.

[0013] In the above technical solution, further, a torsional elastic member is provided at the rotating connection end of the swing clamp and the clamping seat, an extension block is provided at one end of the two swing clamps away from the insulation plate, a connecting plate is provided under the workbench, the two extension blocks and the connecting plate are connected by two second connecting ropes, a second cylinder is provided under the connecting plate, and the output end of the second cylinder is connected to the connecting plate.

[0014] In the above technical solution, further, during the horizontal movement of the heat insulation board on the workbench, the swing clamp can always be in contact with the upper surface of the heat insulation board.

[0015] The beneficial effects of the present invention are:

[0016] 1. By setting a heat insulation plate between the heating plate and the extrusion plate, the heat insulation plate can cover and open the heating plate by horizontal movement, and a clamp is set to clamp and release the end of the packaging bag. In this way, when workers place the end of the packaging bag into the material storage space and take the packaging bag off, the workers will not touch the heating plate due to the obstruction of the heat insulation plate, thereby reducing safety hazards. The clamp can clamp the end of the packaging bag to avoid position displacement of the packaging bag during the sealing process, thereby ensuring the sealing effect of the end of the packaging bag.

[0017] 2. A sliding seat is arranged at the end of the heat insulation board, a first cylinder is arranged under the workbench, the sliding seat is connected to the output end of the first cylinder through a first connecting rope, and a fixed seat is arranged on the workbench, and a linear elastic member is connected between the fixed seat and the sliding seat. In this way, when the first cylinder is started, the sliding seat and the heat insulation board can be pulled horizontally by the first connecting rope to open the heating plate. During this process, the linear elastic member accumulates elastic force. During the resetting process of the first cylinder, the elastic force of the linear elastic member will pull the heat insulation board back to cover the heating plate. The whole process is completed through electronic control, which is easy to operate and reduces the labor intensity of workers.

[0018] 3. By designing the clamping member to be composed of two clamping seats, two swinging clamping plates, two torsion elastic members, two extension blocks, two second connecting ropes, a connecting plate, and a second cylinder, the second cylinder can be started to pull the connecting plate downward to swing the clamping ends of the two swinging clamping plates upward, so that space is left between the swinging clamping plates and the insulation plate for the end of the packaging bag to extend into. In this process, the torsion elastic member accumulates elastic force. During the resetting process of the second cylinder, the elastic force of the torsion elastic member will cause the clamping ends of the two swinging clamping plates to swing downward, and finally cooperate with the insulation plate to clamp the end of the packaging bag. In this way, the clamping process can also be completed by electronic control, which simplifies the steps that workers need to manually operate and improves the sealing efficiency of the packaging bags.

[0031] Example 1

[0032] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a rapid prototyping sealing machine, comprising: a workbench 1, a heating plate 2, an extrusion plate 3, a heat insulation plate 4, a clamping member 5,

[0033] See also Figure 1 A heating plate 2 is provided on the workbench 1. A heating element is provided in the heating plate 2 to heat the surface of the heating plate 2. The heating element may be a resistance wire or a heating rod, etc. A movable extrusion plate 3 is provided above the heating plate 2. A swing frame 6 is provided on the workbench 1. One end of the swing frame 6 is hinged to the workbench 1. The other end of the swing frame 6 is connected to the extrusion plate 3. A material placement space is formed between the heating plate 2 and the extrusion plate 3. The extrusion plate 3 can be close to and away from the heating plate 2 by swinging the swing frame 6 relative to the workbench 1.

[0034] The arrangement of the heating plate 2, the extrusion plate 3, the swing frame 6 and other structures in this embodiment is a relatively mature technology in this field. Therefore, the specific structures of the heating plate 2, the extrusion plate 3 and the swing frame 6 are not limited here. The swing of the swing frame 6 relative to the workbench 1 is manually driven or electrically driven. The electrically driven drive can be realized by an electrically controlled actuator such as a motor or a cylinder. These control methods and arrangement structures are also relatively mature technologies in this field and are not limited here. In order to control the use cost, manual drive can be selected. Manual drive means that the worker manually applies force to the swing frame 6 to make the swing frame 6 swing;

[0035] See also Figure 1 The heat insulation board 4 is arranged between the heating plate 2 and the extrusion plate 3. The heat insulation board 4 is made of heat insulation material, which can reduce the heat transfer. The heat insulation board 4 can move horizontally on the workbench 1. The heat insulation board 4 can cover the heating plate 2 and open the heating plate 2 on the moving track. When the heat insulation board 4 covers the heating plate 2, the workers of the heating plate 2 will not be burned when they touch the heat insulation board 4 during the working process. The horizontal movement of the heat insulation board 4 can be driven by electric control or manually. Figure 1 Shown is a schematic diagram of the heat insulation plate 4 opening the heating plate 2.

[0036] See also Figure 3 The clamping member 5 can cooperate with the heat insulation board 4 to clamp and release the object to be sealed in the material placement space. Any structure in the prior art that can clamp the end of the packaging bag can be used as the clamping member 5 in this embodiment;

[0037] In this embodiment, before sealing the packaging bag, the heating plate 2 is first started for preheating, the extrusion plate 3 is moved away from the heating plate 2, and the insulation plate 4 is moved to cover the heating plate 2. At this time, the worker puts the open end of the packaging bag into the material storage space and places it on the insulation plate 4, and clamps the end of the packaging bag by the clamping member 5. Then the worker moves away from the heating plate 2 and moves the insulation plate 4 to open the heating plate 2. At this time, the open end of the packaging bag comes onto the heating plate 2, and the extrusion plate 3 is pushed toward the heating plate 2 so that the extrusion plate 3 and the heating plate 2 cooperate to seal the open end of the packaging bag. After the sealing is completed, the extrusion plate 3 is moved away from the heating plate 2, the packaging bag is released by the clamping member 5, and the insulation plate 4 is moved to cover the heating plate 2. At this time, the worker removes the packaging bag from the workbench 1 to complete the sealing of a packaging bag.

[0038] Example 2

[0039] This embodiment provides a rapid prototyping sealing machine, which, in addition to the technical solutions of the above embodiments, also discloses a driving method for the heat insulation board 4;

[0040] See also Figure 5A sliding seat 7 is provided at one end of the heat insulation board 4, and the sliding seat 7 is horizontally slidably arranged on the workbench 1. A first cylinder 8 is provided below the workbench 1, and the sliding seat 7 is connected to the output end of the first cylinder 8 through a first connecting rope 9. Specifically, a first through hole is provided on the workbench 1, and the first through hole passes through the upper and lower surfaces of the workbench 1. One end of the first connecting rope 9 is connected to the sliding seat 7, and the other end of the first connecting rope 9 is connected to the output end of the first cylinder 8 after passing through the first through hole. A reversing wheel is provided on the workbench 1 and located on one side of the first through hole, and is connected to the first connecting rope 9, so as to reduce the friction between the first connecting rope 9 and the opening of the first through hole, thereby reducing the wear on the first connecting rope 9 and the workbench 1;

[0041] See also Figure 6 , a fixed seat 10 is provided on the workbench 1, and a linear elastic member 11 is connected between the fixed seat 10 and the sliding seat 7; the linear elastic member 11 is a structure that is deformed under the action of an external force in a linear direction and can restore its original shape after the external force is removed, such as a spring, a rubber product, etc. When the linear elastic member 11 is in its original shape, the heat insulation board 4 covers the heating plate 2, and in the process of the sliding seat 7 and the heat insulation board 4 being pulled horizontally, the linear elastic member 11 will be stretched and accumulate elastic force, and this process is the process of the heat insulation board 4 opening the heating plate 2, and when the horizontal pulling force on the sliding seat 7 and the heat insulation board 4 is removed, the elastic force of the linear elastic member 11 will pull the heat insulation board 4 and the sliding seat 7 back, and this process is the process of the heat insulation board 4 covering the heating plate 2;

[0042] In this embodiment, a control button can be set on the workbench 1 to control the working state of the first cylinder 8. When the first cylinder 8 is started, the sliding seat 7 and the insulation board 4 can be pulled horizontally by the first connecting rope 9 to open the heating plate 2. During this process, the linear elastic member 11 accumulates elastic force. During the resetting process of the first cylinder 8, the elastic force of the linear elastic member 11 will pull the insulation board 4 back to cover the heating plate 2. The whole process is completed through electronic control, which is easy to operate and reduces the labor intensity of workers.

[0043] Example 3

[0044] This embodiment provides a rapid prototyping sealing machine, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a clamping member 5;

[0045] See also Figure 3 A clamping seat 12 is provided on the workbench 1 and on both sides of the heating plate 2. A swing clamping plate 13 is provided on the two clamping seats 12. One end of the two swing clamping plates 13 is rotatably connected to the two clamping seats 12 respectively. The bottom surfaces of the other ends of the two swing clamping plates 13 can cooperate with the upper surface of the insulation plate 4 to clamp the two ends of the object to be sealed;

[0046] See also Figure 2, a torsion elastic member (not shown in the figure) is provided at the rotation connection end of the swing clamping plate 13 and the clamping seat 12. The torsion elastic member is a structure that deforms under the action of external force in the circumferential direction and can restore its original shape after the external force is removed, such as a torsion spring, etc.; an extension block 14 is provided at one end of the two swing clamping plates 13 away from the insulation board 4, a connecting plate 15 is provided under the workbench 1, and the two extension blocks 14 are connected to the connecting plate 15 by two second connecting ropes 16. A second cylinder 17 is provided under the connecting plate 15, and the output end of the second cylinder 17 is connected to the connecting plate 15;

[0047] In this embodiment, the heat insulation board 4 has a certain width, so that during the horizontal movement of the heat insulation board 4 on the workbench 1, the swing clamp 13 can always contact with the upper surface of the heat insulation board 4, and the upper surface of the heat insulation board 4 is relatively rough; in this way, when sealing the end of the packaging bag, the heat insulation board 4 is first moved to cover the heating plate 2, and then the end of the packaging bag is placed on the heat insulation board 4, and the two swing clamps 13 are used to cooperate with the heat insulation board 4 to initially clamp the end of the packaging bag. At this time, there is a gap between the open end of the packaging bag and the swing clamp 13, and the worker needs to hold the other end of the packaging bag with his hand, and then the heat insulation board 4 moves horizontally. Since the upper surface of the heat insulation board 4 is relatively rough, during the horizontal movement of the heat insulation board 4, the packaging bag will follow the heat insulation board 4 to move horizontally for a short distance until the heating plate 2 is fully opened. At this time, the part of the open end of the packaging bag close to the product will contact the heating plate 2, and at this time, the two swing clamps 13 will completely clamp the open end of the packaging bag again, and then the extrusion plate 3 is moved close to the heating plate 2 to seal the open end of the packaging bag;

[0048] In this embodiment, a control button can be set on the workbench 1 to control the working state of the second cylinder 17. When the second cylinder 17 is started and the connecting plate 15 is pulled downward, the clamping ends of the two swinging clamps 13 can be swung upward, leaving space between the swinging clamps 13 and the insulation board 4 for the end of the packaging bag to extend into. In this process, the torsional elastic member accumulates elastic force. During the resetting process of the second cylinder 17, the elastic force of the torsional elastic member can cause the clamping ends of the two swinging clamps 13 to swing downward, and finally cooperate with the insulation board 4 to clamp the end of the packaging bag. In this way, the clamping process can also be completed by electronic control, which simplifies the steps that workers need to manually operate and improves the sealing efficiency of the packaging bag.

[0049] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
