Description

Technical Field

[0001] This invention belongs to the technical field of fabric splicing equipment, specifically relating to a hot-melt automatic fabric splicing machine. Background Technology

[0002] In the fabric processing and production process, splicing is often required for continuous processing. Generally, when changing rolls, the head of the rear roll and the tail of the front roll need to be spliced. Common splicing techniques include sewing and heat splicing. Heat splicing is widely used because it has no seams and does not increase thickness. Currently, existing heat-sealing type fabric splicing machines typically involve overlapping the head and tail of the rear roll of fabric on the splicing worktable above the lower pressure plate. The upper pressure plate is then driven to move the heating wire downwards, causing it to contact the lower pressure plate. The heating wire heats up, fusing the two pieces of fabric together and separating them from the edges. The heating wire is then turned off, allowing the seam to cool and solidify, thus completing the splicing process. However, existing heat-sealing machines do not flatten and fix the fabric before the heating wire contacts it. When the heating wire approaches the fabric, the fabric may wrinkle or shift due to machine vibration, resulting in uneven seams. Furthermore, during the splicing process, the fabric must be manually pulled through the upper pressure plate and the bottom of the heating wire. Misoperation can easily cause injury to the operator, posing a safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a heat-fusion automatic fabric splicing machine to solve the problems of existing heat-fusion fabric splicing machines not flattening and fixing the fabric before the heating wire comes into contact with the fabric, and the existence of safety hazards.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A hot-melt automatic fabric splicing machine includes a frame. A fabric receiving mechanism and a fabric releasing mechanism are sequentially arranged from top to bottom on one side of the frame. A lower pressure plate is fixedly installed on the frame. A gantry frame is fixedly installed on the frame. A driveable lifting mounting frame is provided inside the gantry frame. An upper pressure plate is fixedly installed inside the mounting frame, and the upper pressure plate is directly above the lower pressure plate. Side plates are rotatably installed on both sides of the mounting frame. Multiple springs are fixedly connected between the two side plates. Rollers are rotatably installed at the bottom of both side plates. A heating wire is fixedly installed at the bottom of the upper pressure plate, and the heating wire is located between the springs and the bottom of the rollers.

[0006] Preferably, a plurality of second electric push rods are fixedly installed on the top of the gantry frame, and the telescopic ends of the plurality of second electric push rods are all fixedly connected to the top of the mounting frame.

[0007] Preferably, a first guide roller and a second guide roller are rotatably connected inside the frame, and the bottom of the first guide roller and the top of the second guide roller are not higher than the top of the lower pressure plate.

[0008] Preferably, two lead screws are symmetrically rotatably connected to the frame, and two first motors are fixedly installed on one side of the frame. The output ends of the two first motors are respectively fixedly connected to the two lead screws. A clamp seat is screwed onto the two lead screws, and a clamping plate is rotatably connected to one side of the clamp seat.

[0009] Preferably, a third electric push rod is fixedly connected to the side of the clamp seat away from the clamp plate, and an L-shaped connecting frame is fixedly connected to the telescopic end of the third electric push rod. A sliding groove is provided on the clamp plate, and the sliding groove is located above the connection between the clamp plate and the clamp seat. One end of the connecting frame is slidably connected to the sliding groove.

[0010] Preferably, the frame is provided with a collection groove, and the collection groove is located below the fixture seat.

[0011] Preferably, the fabric taking-up mechanism includes a pressure roller and a drive roller arranged sequentially from top to bottom. The drive roller is rotatably connected to the frame. Two first electric push rods are symmetrically fixedly connected to both sides of the frame, and the telescopic ends of the two first electric push rods are fixedly connected to sliders. The pressure roller is rotatably connected between the two sliders.

[0012] Preferably, a second motor is fixedly connected to one side of the frame, and the output end of the second motor is fixedly connected to one end of the drive roller.

[0013] Preferably, the fabric feeding mechanism includes an arc-shaped support frame fixedly connected to the frame and two guide rods located above the two ends of the support frame. Two limiting frames are symmetrically slidably connected to the two guide rods. Multiple limiting rods are fixedly connected to the top of each of the two limiting frames, and the limiting rods on the two limiting frames are arranged facing each other.

[0014] Preferably, a fixing bolt is screwed onto one side of the limiting frame, and one end of the fixing bolt can extend into the limiting frame and abut against one of the guide rods.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The present invention is provided with side plates, rollers and springs. When the drive mounting frame moves the heating wire downward, the rollers first abut against the fabric, so that the fabric abuts against the frame. When the mounting frame continues to move downward, the side plates rotate in the mounting frame. At the same time, the rollers move to both sides to flatten the fabric. After flattening, the rollers can roll on the fabric to prevent scratching the fabric. When the two side plates rotate, the springs are stretched, so that the springs apply tension to the two side plates. Then the rollers make the fabric still abut against the frame and fix it, thereby preventing the fabric from wrinkling or moving and making the seam neat.

[0017] (2) The present invention is provided with a lead screw and a clamp seat. By driving the lead screw to rotate, the clamp seat can be moved along the lead screw axis. The head of the rear roll and the tail of the front roll are fixedly clamped on the clamp seat by the clamp plate, so that the clamp seat can pull the fabric through the bottom of the upper pressure plate and the heating wire, preventing the machine from causing injury to the operator due to misoperation, and also reducing the labor intensity of the operator and improving work efficiency.

[0018] (3) The present invention is provided with a collection trough, which can recycle the corner fabric. After the fabric is finished, the corner fabric is still clamped on the clamp seat. When the fabric is clamped, it is clamped from the bottom of the clamp seat, which can move the clamp seat to the top of the collection trough and release the clamp plate, so that the corner fabric falls directly into the collection trough. The corner fabric can be recycled and reused, and the operation is simple.

[0019] (4) The present invention is provided with a limiting frame. The rear roll is placed in the arc-shaped support frame. Then the limiting frames on both sides are moved to abut against the two ends of the rear roll, and the two sides of the rear roll are aligned with the two sides of the front roll. This prevents the rear roll from moving left and right when it rotates and releases the fabric in the support frame, so that the seam between the front roll and the rear roll is neat and flush. In addition, the limiting rod on the limiting frame can prevent the fabric roll from jumping and rolling off the support frame. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 As shown, the present invention provides the following technical solution:

[0028] A hot-melt automatic fabric splicing machine includes a frame 1. A fabric receiving mechanism and a fabric feeding mechanism are arranged sequentially from top to bottom on one side of the frame 1. A lower pressure plate 18 is fixedly installed on the frame 1. A gantry frame 2 is fixedly installed on the frame 1. A driveable lifting mounting frame 11 is provided inside the gantry frame 2. An upper pressure plate 29 is fixedly installed inside the mounting frame 11, and the upper pressure plate 29 is located directly above the lower pressure plate 18. Side plates 12 are rotatably installed on both sides of the mounting frame 11. Multiple springs 30 are fixedly connected between the two side plates 12. Rollers 13 are rotatably installed at the bottom of the two side plates 12. An electric heating wire 28 is fixedly installed at the bottom of the upper pressure plate 29, and the electric heating wire 28 is located between the springs 30 and the bottom of the rollers 13.

[0029] Multiple second electric push rods 10 are fixedly installed on the top of the gantry frame 2, and the telescopic ends of the multiple second electric push rods 10 are fixedly connected to the top of the mounting frame 11.

[0030] Based on the above-disclosed structure, when performing the fabric splicing process:

[0031] First, the fabric from the front roll tail and the rear roll head are pulled out from the fabric receiving mechanism and the fabric releasing mechanism, respectively. Then, the fabric from the front roll tail and the rear roll head overlap and passes between the upper pressure plate 29 and the lower pressure plate 18, and is placed above the lower pressure plate 18. Then, the second electric push rod 10 is activated to drive the mounting frame 11 to move downward, thereby moving the upper pressure plate 29 and the heating wire 28 closer to the fabric. At the same time, the mounting frame 11 drives the side plate 12 and the roller 13 to move downward. When the mounting frame 11 moves downward, the roller 13 first contacts the fabric, and then the second electric push rod 10 continues to push out. The telescopic end allows the side plate 12 to rotate on the mounting frame 11, and the two rollers 13 move to the sides respectively. At the same time, the two side plates 12 stretch the spring 30. Due to the elasticity of the spring 30, the rollers 13 always exert a downward force on the fabric, so that the bottom of the fabric can fit against the frame 1. If there are wrinkles on the fabric, the rollers 13 can stretch and flatten the fabric when they move to the sides. If the mounting frame 11 needs to be moved further down after the fabric is flattened, the rollers 13 can roll on the fabric to prevent scratching the fabric surface until the heating wire 28 and the upper pressure plate 29 press against the fabric downward.

[0032] The heating wire 28 heats up, causing the two pieces of fabric at the front roll tail and the rear roll head to fuse together and separate from the edge fabric at the heating wire 28. The heating wire 28 is turned off to allow the seam to cool and solidify. Then the second electric push rod 10 is activated to retract the telescopic end, so that the fabric is no longer pressed and fixed, and the fabric can be removed, thus completing the fabric splicing process at the front roll tail and the rear roll head.

[0033] Preferably, a first guide roller 7 and a second guide roller 26 are rotatably connected inside the frame 1, and the bottom of the first guide roller 7 and the top of the second guide roller 26 are not higher than the top of the lower pressure plate 18. Based on this, when the fabric at the tail of the front roll and the head of the rear roll are pulled out from the fabric taking-up mechanism and the fabric releasing mechanism, both pieces of fabric pass between the first guide roller 7 and the second guide roller 26. Since the bottom of the first guide roller 7 and the top of the second guide roller 26 are not higher than the top of the lower pressure plate 18, the fabric can adhere to the upper surface of the lower pressure plate 18 on the frame 1.

[0034] Regarding the pulling of the fabric through the upper pressure plate 29 and the lower pressure plate 18, the preferred structure is as follows:

[0035] Two lead screws 8 are symmetrically rotatably connected on the frame 1. Two first motors 9 are fixedly installed on one side of the frame 1. The output ends of the two first motors 9 are fixedly connected to the two lead screws 8 respectively. A clamp seat 14 is screwed onto the two lead screws 8. A clamping plate 25 is rotatably connected to one side of the clamp seat 14.

[0036] A third electric push rod 15 is fixedly connected to the side of the clamp seat 14 away from the clamp plate 25. An L-shaped connecting frame 16 is fixedly connected to the telescopic end of the third electric push rod 15. A sliding groove 27 is provided on the clamp plate 25, and the sliding groove 27 is located above the connection between the clamp plate 25 and the clamp seat 14. One end of the connecting frame 16 is slidably connected in the sliding groove 27.

[0037] As can be seen from the above, firstly, the clamp seat 14 is located on the side of the frame 1 near the take-up mechanism and the unwinding mechanism. After the fabric at the tail of the front roll and the head of the rear roll passes between the first guide roller 7 and the second guide roller 26, it is placed between the clamp plate 25 and the clamp seat 14. The third electric push rod 15 is activated to retract the telescopic end, so that one end of the connecting frame 16 slides in the slide groove 27, thereby pushing the clamp plate 25 to rotate on the clamp seat 14, so that the bottom of the clamp plate 25 is close to the clamp seat 14, so that the clamp plate 25 and the clamp seat 14 fix and clamp the fabric at the tail of the front roll and the head of the rear roll. Then, the first motor 9 is activated to drive the lead screw 8 to rotate, so that the clamp seat 14 moves along the axial direction of the lead screw 8 and cooperates with the clamp plate 25 to pull the fabric through the upper pressure plate 29 and the lower pressure plate 18. This process does not require the operator to manually pass the fabric through the upper pressure plate 29 and the lower pressure plate 18, which can prevent the machine from causing injury to the operator due to misoperation, and can also save manpower and increase efficiency.

[0038] In addition, a collection trough 17 is provided on the frame 1, and the collection trough 17 is located below the clamp seat 14. Based on this, after the fabric splicing process of the front roll tail and the rear roll head is completed, the edge fabric is clamped between the clamping plate 15 and the clamp seat 14. The first motor 9 can be started to drive the lead screw 8 to move the clamp seat above the collection trough 17. Then, the third electric push rod 15 is started to extend the telescopic end, so that the clamping plate 25 releases its clamping grip, allowing the edge fabric to fall downward into the collection trough 17. The edge fabric can be recycled and reused without manual cleaning, making the operation convenient.

[0039] Preferably, the take-up mechanism can be connected to an external fabric processing device. The take-up mechanism pulls out the fabric from the unloading mechanism, so that the fabric processing device processes the fabric output by the take-up mechanism. After the current roll of fabric is completely released from the unloading mechanism, a new rear roll needs to be placed in the unloading mechanism. Then, the head of the rear roll is connected to the tail of the front roll to connect the front roll and the rear roll, so that continuous processing can be achieved.

[0040] Specifically, the fabric taking-up mechanism includes a pressure roller 3 and a drive roller 4 arranged sequentially from top to bottom. The drive roller 4 is rotatably connected inside the frame 1. Two first electric push rods 5 are symmetrically fixedly connected to both sides of the frame 1, and the telescopic ends of the two first electric push rods 5 are fixedly connected to sliders 6. The pressure roller 3 is rotatably connected between the two sliders 6. A second motor 19 is fixedly connected to one side of the frame 1, and the output end of the second motor 19 is fixedly connected to one end of the drive roller 4. Based on this, when the take-up mechanism pulls the fabric out from the unloading mechanism, the fabric passes between the pressure roller 3 and the drive roller 4, driving the first electric push rod 5 to push out the telescopic end, causing the slider 6 to drive the pressure roller 3 to move downward and press the fabric against the drive roller 4. Then, the second motor 19 is started to drive the drive roller 4 to rotate. Due to the friction of the fabric, the fabric is output from between the pressure roller 3 and the drive roller 4 and pulled out from the unloading mechanism until the current roll of fabric is completely released from the unloading mechanism. Then, the second motor 19 is turned off and the first electric push rod 5 is started to retract the telescopic end, so that the pressure roller 3 no longer presses the fabric, making it easier to pull out the fabric at the end of the previous roll during the fabric splicing process.

[0041] Specifically, the fabric feeding mechanism includes an arc-shaped support frame 24 fixedly connected to the frame 1 and two guide rods 20 located above the two ends of the support frame 24. Two limiting frames 21 are symmetrically slidably connected to the two guide rods 20. Multiple limiting rods 23 are fixedly connected to the top of each of the two limiting frames 21, and the limiting rods 23 on the two limiting frames 21 are arranged facing each other. A fixing bolt 22 is screwed onto one side of the limiting frame 21, and one end of the fixing bolt 22 can extend into the limiting frame 21 and abut against one of the guide rods 20. Based on this, after the front roll of fabric is completely released from the fabric feeding mechanism, the fixing bolt 22 is rotated so that the fixing bolt 22 no longer abuts against the guide rod 20. Then, the limiting frame 21 is moved to both sides along the guide rod 20, thereby driving the limiting rod 23 to move to both sides, so that the limiting rod 23 does not block the feeding. Then, the rear roll is placed in the arc-shaped support frame 24. Then, the two limiting frames 21 are moved along the guide rod 20 to approach the two ends of the rear roll, and the two ends of the rear roll are aligned with the two ends of the front roll tail. The fixing bolt 22 is rotated into the limiting frame 21 and pressed against the guide rod 20, so that the limiting frame 21 is fixed on the guide rod 20, preventing the rear roll from moving left and right when rotating and feeding the fabric, which would cause uneven seams. Then, the head of the rear roll is pulled out from between two adjacent limiting rods 23 and joined with the tail of the front roll. The limiting rod 23 can prevent the rear roll from rolling off the support frame 24 when the fabric is pulled.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
