Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to a positioning edge banding machine for multiple bag openings. Background Art

[0002] The multiple bag opening positioning edge banding machine can perform efficient and accurate edge banding on the edges of composite bags by precisely controlling parameters such as temperature, speed and pressure. This equipment is widely used in the edge banding processing of composite materials such as plastic bags, food bags, and clothing bags. The working principle of the multiple bag opening positioning edge banding machine mainly includes five steps: preheating, gluing, laminating, pressing and trimming. Through the above steps, the material processing is completed, and the original single pockets are bonded to obtain composite pockets. The multiple bag opening positioning edge banding machine is an efficient and accurate edge banding equipment, which is of great significance to improving the work efficiency and product quality of composite bag edge banding.

[0003] In the public document with announcement number CN 213798374U, an automatic edge sealing machine for plastic bags is disclosed, comprising a base, a feeding assembly and a receiving assembly are respectively arranged on the front and rear sides of the base, an edge sealing plate is arranged on the top of the base, an electric heating wire is arranged on the edge sealing plate, a door frame is fixedly connected to the top of the base, a rotating seat is fixedly connected to the center of the top of the door frame, a rotating rod is rotatably connected to the inner cavity of the rotating seat, the bottom of the rotating rod passes through the inner cavity of the rotating seat and is fixedly connected to a screw, a threaded sleeve is threadedly connected to the outer wall of the screw, a pressure strip is fixedly connected to the bottom of the threaded sleeve, and the pressure strip is located above the electric heating wire. The utility model arranges a base, a feeding assembly, a receiving assembly, a door frame, a screw, a threaded sleeve, etc., so that when the edge of the plastic bag is sealed, the screw and the receiving assembly can be driven to rotate by a rotating motor respectively, and the arrangement of an incomplete bevel gear and an incomplete gear enables the receiving assembly and the screw to cooperate, thereby realizing automatic edge sealing of the plastic bag.

[0004] In the above-mentioned public documents, automatic edge sealing is completed by a motor-pass component. Although this technical solution can automatically complete the edge sealing of the bag mouth, it still has some defects. If you want to obtain composite bags or want to complete the edge sealing of a large number of composite bags within a period of time, you still need to transport the materials in sequence, and it takes a certain amount of time to achieve this goal. There is still room for improvement in work efficiency and the degree of automation. Utility Model Content

The specific technical solution is as follows:

[0007] After adopting the above technical scheme, the utility model has the following advantages: the materials to be processed are accumulated on the feeding conveyor belt through the material clamps, and the logistics accumulated in the material clamps are clamped and pulled out by the double-sided clamps, and the materials are quickly transported to the limit frame on the processing conveyor belt through the extension and contraction of the telescopic arm and the scaling of the double-sided clamps, and the hot melt adhesive of the hot melt adhesive furnace is transported to the top of the limit frame by the guide pipe, and the dripping position of the hot melt adhesive is set, and the air in the edge-sealed processing materials is discharged by the rolling of the rollers to make them better bonded, and then the processed materials are quickly cooled down by the cold air fan and transported to the next process.

[0008] Furthermore, the double-sided clamp is provided with a first clamp and a second clamp, the shrinking band can be connected to the external system through the central axis and the stretching time can be preset to control the closing of the clamp, the first clamp is controlled to rotate 180° by the central axis after clamping the material through the shrinking band at the tail and the clamp spring, and the clamp telescopic arm quickly extends to the limit frame after the second clamp clamps the material and controls the opening of the clamp through the clamp spring to complete the transportation of the material.

[0009] Furthermore, the feeding conveyor belt is provided with a groove edge derived along the feeding conveyor belt, and the material fixture includes a material baffle, a material top baffle arranged above the material baffle, and a material side baffle symmetrically arranged at both ends of the material baffle and located below the material top baffle, and the material top baffle forms an angle of <90° with the feeding conveyor belt in the horizontal direction.

[0011] Furthermore, a processing pad with a certain thickness is arranged in the limit frame, and the limit frame is a rubber belt with a certain elasticity. The limit frame can continue to transport materials as the conveyor belt rotates and rolls.

[0012] Furthermore, both ends of the roller connecting shaft are connected to the roller telescopic arms, and the roller rotates when subjected to external force.

[0013] Furthermore, the transport speed of the feeding conveyor belt is constantly greater than the transport speed of the processing conveyor belt, and there is a fixed speed difference between the transport speeds of the two conveyor belts.

DETAILED DESCRIPTION

[0020] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. It should be pointed out that the following relevant embodiments are only preferred embodiments for better illustrating the present invention itself, and the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technical personnel in this technical field.

[0021] See also Figures 1 to 4 As shown, the utility model provides a positioning edge banding machine for multiple bag openings, including a conveyor belt and a workbench 11, a hot melt adhesive furnace 3, a clamp telescopic arm 403, a roller 5 and a cold air blower 6, the conveyor belt is divided into a feeding conveyor belt 8 and a processing conveyor belt 9, the feeding conveyor belt 8 is located above the processing conveyor belt 9 and is provided with a material fixture 1 at the end, the processing conveyor belt 9 is provided with a limit frame 2 for material processing, the hot melt adhesive furnace 3 is arranged above the workbench and connected to the guide pipe 10, the other end of the guide pipe 10 is located above the horizontal movement track of the limit frame 2, a rotatable central axis 407 is provided on the clamp telescopic arm 403, the central axis 407 is connected to the double-sided clamp 4 through the connecting shaft 402 on the double-sided clamp 4, a shrinking belt 404 connected to the tail end of the clamp is provided at the center of the connecting shaft 402, the roller 5 and the cold air blower 6 are sequentially arranged on the workbench and are located in front of the clamp telescopic arm 403 along the forward direction of the conveyor belt.

[0022] The conveyor belt is divided into a processing conveyor belt 9 and a feeding conveyor belt 8. The running speed of the feeding conveyor belt 8 is greater than that of the processing conveyor belt 9. In order to prevent the feeding conveyor belt 8 from falling, a material fixture 1 is arranged on the feeding conveyor belt 8. The material fixture 1 is divided into a material baffle 101 for preventing the material from falling, a material top baffle 102 for preventing the material from accumulating too much, and a side baffle 103 for preventing the material from falling from the feeding conveyor belt 8.

[0023] The material baffle 101 and the conveyor belt have a certain gap and a certain angle in the vertical direction. When the material is transported forward under the action of the feeding conveyor belt 8, it is clamped under the clamping of the material baffle 101 and the feeding conveyor belt 8. The protruding amount of the material can be clamped by adjusting the angle of the material baffle 101 and the feeding conveyor belt 8. When the subsequent material is blocked in the front, it is accumulated between the feeding conveyor belt 8 and the material fixture 1, forming a material stacking area.

[0024] The angle formed by the material top baffle 102 and the feeding conveyor belt 8 in the horizontal direction along the transport direction of the feeding conveyor belt 8 is less than 90°. The angle formed in this way can better prevent the material from falling due to accumulation.

[0025] The double-sided clamp 4 is a spring sealing clamp, which is closed by the elastic force of the clamp spring 401, and is connected to the central axis 407 through the connecting shaft 402, and the two ends of the central axis 407 are respectively connected to the clamp telescopic arms 403, and the double-sided clamp 4 is divided into a first clamp 405 and a second clamp 406, and the tail ends of the first clamp 405 and the second clamp 406 are both provided with a shrink belt 404, which is an overall elastic connecting belt and is connected to the center of the connecting shaft 402. The hole in the center of 02 is directly connected to the clamp telescopic arm 403, and the shrinkage band 404 is controlled by an external machine through the central axis 407, or other connection methods can be adopted to complete the connection with the external machine, and the stretching of the shrinkage band 404 is completed by the preset of the external machine. When the double-sided clamp 4 rotates, the shrinkage band 404 is tightened according to the preset content, so that one side of the double-sided clamp 4, such as the clamping mouth of the first clamp 405, is opened to complete the opening of the clamp, and the shrinkage band 404 is loosened after the opening is aligned with the material in the material fixture 1 according to the preset rotation angle during the rotation process, and the clamping mouth of the first clamp 405 is closed by the elastic force of the clamp spring 401 to clamp the material tightly. Under the driving action of the rotation of the central axis 407, the first clamp 405 connected to the connecting shaft 402 draws the material from the material fixture 1, and rotates 180° to rotate the second clamp 406 to the baffle of the material fixture 1. Similarly, the shrinkage band 406 at the tail of the second clamp 406 is controlled by the preset of the external system. 04, complete the material that the second clamp 406 extends out from the mouth of the material baffle 101, and then relax the shrink belt 404 here, and also complete the pulling of the material through the clamp spring 401, and then the clamp telescopic arm 403 quickly descends, and when the clamp telescopic arm 403 stops above the limit frame 2, the shrink belt 404 on the tail of the first clamp 405 and the second clamp 406 is controlled in turn again, so that the material on the clamp mouth falls into the limit frame 2 on the processing conveyor belt 9 below, completing the transportation of the material.

[0026] The hot melt glue furnace 3 can melt the hot melt glue. The melted hot melt glue can be guided by the guide tube 10 at the bottom of the hot melt glue furnace 3 to the top of the limit frame 2, and enter the limit frame 2 through the guide tube 10 to complete the coverage of the glue. At this time, the clamp telescopic arm 403 places the material above the glue to complete the covering of the material.

[0027] A branch pipe 1001 is provided above the guide pipe 10, and the branch pipe 1001 is connected to the air pressure pump 7. Under the action of the air pressure pump 7, a large amount of air pressure is generated by the air pressure pump 7 and enters the main pipe of the guide pipe 10 from the branch pipe 1001, thereby completing the isolation of the hot melt glue and preventing the hot melt glue from dripping into the non-limiting frame 2 area on the processing conveyor belt 9, causing damage to the processing conveyor belt 9.

[0028] The laminated material is in the limit frame 2 and, as the processing conveyor belt 9 continues to move, it comes under the roller 5. A roller connecting shaft 502 runs through the center of the roller 5. The roller connecting shaft 502 is connected to the roller telescopic arm 501. The roller 5 is driven to move up and down by the extension and retraction of the roller telescopic arm 501. The roller 5 is pressed on top of the material by the action of the roller telescopic arm 501. Driven by the processing conveyor belt 9, the roller 5 itself also rolls, completing the pressurization of the edge sealing.

[0029] After the material is pressurized by roller 5, the bubbles in the bonding part and the hot melt adhesive are all pressed open, making the bonding of the material tighter and more comprehensive. Due to the high heat of the hot melt adhesive, subsequent processing is required in time to avoid the hot melt adhesive damaging the surface of the material due to high heat and causing irreversible damage, causing cracks between the damaged part and the non-damaged part, resulting in cracking of the material and falling off of the bonded part.

[0030] In order to prevent the above phenomenon from occurring, an air cooler 6 is added behind the roller 5 in the box. The air cooler 6 will blow out cold air and fully cover the part in the upper limit frame 2 of the processing conveyor belt 9, so that the cold air can be fully blown to the material in the limit frame 2 that has just been pressurized by the roller 5, so that it can be quickly cooled to achieve a cooling effect.

[0031] In this embodiment, the transport speed of the feeding conveyor belt 8 is slightly greater than the transport speed of the processing conveyor belt 9, and the feeding conveyor belt 8 is positioned above the processing conveyor belt 9 and does not extend to the entire box body. When a portion of material has more composite bags that require edge sealing, the greater the difference in transport speeds between the two, and the transport speed of the feeding conveyor belt 8 is always greater than the transport speed of the processing conveyor belt 9.

[0032] The limit frame 2 on the processing conveyor belt 9 is made of rubber material with a certain flexibility. It can follow the processing conveyor belt 9 to rotate in an entire closed loop without causing irreversible deformation. The limit frame 2 is only used to limit the movement of materials on the conveyor belt to prevent the materials from being positioned unfixed due to uneven force. A thickened base is provided in the limit frame 2 to prevent the conveyor belt itself from being damaged due to the heat of the hot melt adhesive during long-term use. In order to avoid damage to the processing conveyor belt 9, a layer of ductile rubber skin is added to the bottom of the conveyor belt to prevent damage to the processing conveyor belt 9.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
