Description

Technical Field

[0001] This utility model relates to the technical field of canvas processing equipment, and in particular to a novel splicing and binding machine. Background Technology

[0002] In the production process of coated canvas, in order to ensure the structural strength of the canvas edge, it is usually necessary to wrap the reinforcing rope inside the canvas edge. Currently, the commonly used wrapping methods are one is to use a sewing-type edge-wrapping machine to sew the reinforcing rope inside the canvas edge, and the other is to use a heat-bonding edge-wrapping machine to wrap the reinforcing rope inside the canvas edge.

[0003] Regarding the structure of the heat-bonding type edge-binding machine, it typically uses a heating device to heat the edge of the canvas. After folding it in half and wrapping the reinforcing rope inside the edge of the canvas, it is then squeezed by two rollers positioned opposite each other to achieve the edge-binding work of the canvas. However, the two rollers are usually designed to be relatively fixed. On the one hand, it cannot be used for wrapping reinforcing ropes of various specifications. On the other hand, it is also difficult for the folded edge of the canvas to be squeezed between the two rollers, so the edge-binding operation of the edge-binding machine still has certain limitations. Utility Model Content

[0004] In order to improve the problems of the edge banding machine in the actual use of the above-mentioned background technology, this utility model provides a new type of splicing edge banding machine.

[0005] The novel web-joining and edge-binding machine provided by this utility model adopts the following technical solution: A novel edge-sealing machine includes a worktable and a support mounted thereon. The support is equipped with a heating device for heating the edges of canvas and an edge-pressing device for pressing the heated canvas edges together. By employing this technical solution, the heating device, in conjunction with the edge-pressing device, first heats and softens the canvas edges, then presses them together using the edge-pressing device. This solves the problems of loosening and weak adhesion in traditional cold-pressed edge-sealing, improving the strength and durability of the edge-sealing connection.

[0006] Furthermore, the edge-pressing device includes a horizontal arm and an edge-pressing wheel elastically disposed below it. A lower roller is provided on the worktable corresponding to the edge-pressing wheel. A connecting rod extending from both ends of the horizontal arm is vertically slidably disposed inside the horizontal arm. An elastic element is provided between the connecting rod and the horizontal arm, and the direction of the elastic force exerted on the connecting rod by the elastic element is downward. The edge-pressing wheel is located at the lower end of the connecting rod. By adopting the above technical solution, the edge-pressing wheel can automatically adjust its downward pressing amplitude according to the canvas thickness, adapting to the edge-binding requirements of canvases of different thicknesses, and has strong versatility. A locking head is provided at the upper end of the connecting rod.

[0007] Furthermore, the elastic element includes a guide rod vertically fixed inside the cross arm, and a lifting block fixed to the middle of the connecting rod and slidingly engaged with the guide rod. A spring is sleeved on the outer ring of the guide rod on the upper side of the lifting block. By adopting the above technical solution, the guide rod can limit the sliding direction of the lifting block, prevent the connecting rod from causing the pressing wheel to shift laterally, ensure that the pressing wheel is always aligned with the lower roller, and avoid the problem of misalignment in the edge binding. Furthermore, the lower roller is connected to a geared motor, which drives the canvas conveyor to achieve continuous operation. The upper edge of the lower roller protrudes from the surface of the worktable and forms a clamping force with the pressing wheel to ensure smooth canvas conveying.

[0008] Furthermore, the heating device includes a handle rotatably mounted on the cross arm, with a clamp connected to the front end of the handle and a heating cylinder fixed thereon, and a fan connected to the rear end of the heating cylinder via a pipe. The output end of the heating cylinder is bent and has a duckbill opening that can be aligned with the edge of the canvas by rotation. The duckbill opening concentrates the hot air onto the edge of the canvas, improving heat utilization efficiency.

[0009] Furthermore, a contact sensor capable of sensing the rotational contact of the grip is installed on the cross arm, and a control console is installed on the bracket, which is communicatively connected to both the fan and the contact sensor.

[0010] Furthermore, a horizontal folding plate is fixedly connected to one side of the bracket, and a gap is provided between the folding plate and the workbench surface to guide the folding of the canvas; a vertical guide side plate is fixedly provided on the front side of the folding plate to ensure that the edge of the folded canvas is always aligned with the pressure roller, so as to prevent the canvas from shifting during the feeding process.

[0011] In summary, this utility model has the following beneficial technical effects: 1. This utility model provides a novel edge-sealing machine that integrates canvas folding, heating, and edge-pressing steps. Before the canvas enters the edge-pressing device, the clamp is pried up to lift the edge-pressing roller, making it easier for the canvas to enter between the edge-pressing roller and the lower roller. The elastic element inside the edge-pressing device can realize the adaptive pressure adjustment of the edge-pressing roller for canvases of different specifications and thicknesses, ensuring that the canvas is tightly bonded and meeting the wrapping operation of reinforcing ropes of various specifications.

[0012] 2. A contact sensor is installed on the cross arm. When the handle is rotated to the working position, that is, when the heating cylinder is aligned with the edge-binding position, the contact sensor can sense the rotation of the handle and trigger the start of the fan. The gas is heated by the heating cylinder and then accurately delivered to the edge-binding position of the canvas to melt the folded surface of the canvas. When the handle is rotated back to the non-working position, the fan is automatically turned off. There is no need for manual switching, which is highly automated and prevents the safety hazards caused by the hot air output in the non-working state. Attached Figure Description

[0016] Utility Model Embodiment 1 discloses a novel web-jointing edge-binding machine.

[0017] Reference Figure 1 , Figure 3 A novel edge-binding machine includes a workbench 1, a support 2 on the workbench 1, and a heating device 3 on the support 2 capable of heating the edge of the canvas. The heating device 3 includes a handle 31 rotatably mounted on a cross arm 41. The front end of the handle 31 is connected to a clamp 32 and a heating cylinder 33 is fixed thereon. The output end of the heating cylinder 33 is bent and has a duckbill 331 that can be aligned with the edge-binding position of the canvas by rotation. The rear end of the heating cylinder 33 is connected to the air outlet of a fan 34 through a pipe.

[0018] As a preferred structure, a contact sensor 411 capable of sensing the rotational contact of the handle 31 is installed on the cross arm 41, and a control console 5 is installed on the bracket 2. The control console 5 is communicatively connected to the fan 34 and the contact sensor 411. When the handle 31 rotates to the working position, that is, when the heating cylinder 33 is aligned with the edge, the contact sensor 411 triggers the start of the fan 34. When the handle 31 rotates back to the non-working position, the fan 34 automatically shuts off, eliminating the need for manual switching and preventing safety hazards caused by the output heat in the non-working state.

[0019] Reference Figure 1 , Figure 2 The support 2 is equipped with a pressing device 4 that can press the edge of the heated canvas together. The pressing device 4 includes a horizontal arm 41 and a pressing wheel 45 elastically located on its lower side. The worktable 1 is provided with a lower roller 46 corresponding to the pressing wheel 45. The lower roller 46 and the pressing wheel 45 cooperate to form a clamping structure. When the canvas passes between the two, it is pressed together. The lower roller 46 is driven by a reduction motor, and the upper edge of the lower roller 46 protrudes from the surface of the worktable 1. The horizontal arm 41 is vertically slidably provided with a connecting rod 42 extending out of the horizontal arm 41 at both ends. An elastic element 43 is provided between the connecting rod 42 and the horizontal arm 41, and the direction of the elastic force of the connecting rod 42 by the elastic element 43 is downward. The pressing wheel 45 is located at the lower end of the connecting rod 42. The upper end of the connecting rod 42 is provided with a clamp 44. The clamp 44 is pried up by a pry bar 47 and drives the pressing wheel 45 to rise. The front end of the pry bar 47 is vertically connected to a clamping plate. The clamping plate is provided with a U-shaped opening adapted to the lifting rod 47. The lever has a bayonet-shaped design, and the rear end of the pry bar 47 is bent and fitted with a handle.

[0020] As a preferred structure, the elastic element 43 includes a lifting block 433 fixedly mounted on the connecting rod 42. The lifting block 433 has vertical guide rods 431 passing through both ends and slides up and down along the guide rods 431. Both ends of the guide rods 431 are fixed inside the cross arm 41. A spring 432 is sleeved on the outer ring of the guide rods 431 on the upper side of the lifting block 433. That is, a spring 432 is sleeved on the guide rods 431, with its end abutting between the lifting block 433 and the upper wall of the cross arm 41. The spring 432 is in a pre-compressed state. In its natural state, the elastic force of the spring 432 pushes the lifting block 433 to slide downward, so that the pressure wheel 45 presses tightly against the lower roller 46.

[0021] Reference Figure 1 , Figure 4 A horizontal folding plate 6 is fixedly connected to one side of the bracket 2. A guide plate 62 with a smooth lower surface is fixed to the bottom of the folding plate 6, and a gap is provided between the folding plate 6 and the surface of the workbench 1 to guide the canvas folding. A vertical guide side plate 61 is fixedly provided on the front side of the folding plate 6.

[0022] The implementation principle of a novel fabric binding machine according to embodiment 1 of the utility model is as follows: when the canvas moves along the binding path on the worktable 1, it is guided and folded by the folding plate 6 in sequence, the heating device 3 completes the gluing, and then the pressing device 4 completes the pressing and fixing. After bending the first end of the canvas with a flat edge, it is placed into the channel between the folding plate 6 and the workbench 1, and the canvas is conveyed along a fixed track. Rotate the handle 31 so that the duckbill 331 of the output end of the heating cylinder 33 is aligned with the edge of the canvas. At the same time, the contact sensor 411 senses that the handle 31 is close to the contact and sends an electrical signal. After receiving the electrical signal, the PLC controller built into the control console 5 controls the fan 34 to output gas. The gas is heated by the heating cylinder 33 and then output to the edge to melt the folded surface of the canvas. The first end of the canvas is conveyed to the front of the edge pressing device 4. The pry bar 47 is used to pry up the clamp 44 and drive the edge pressing wheel 45 to rise. After the canvas is completely between the edge pressing wheel 45 and the lower roller 46, the pry bar 47 is released. The edge pressing wheel 45 is reset under the elastic force of the elastic element 43. The elastic element 43 drives the edge pressing wheel 45 to press down and complete the edge pressing and fixing of the canvas according to the appropriate pressure.

[0023] Utility Model Embodiment 2 discloses a novel web-jointing edge-binding machine.

[0024] Reference Figure 5 A novel edge-sealing machine includes a worktable 1 with a support 2 on it. An edge-sealing device 4 for pressing the edges of heated canvas is mounted on the support 2. The edge-sealing device 4 includes a horizontal arm 41 and an edge-sealing wheel 45 elastically positioned below it. A connecting rod 42, extending from both ends of the horizontal arm 41, slides vertically inside the horizontal arm 41. An elastic element 43 is provided between the connecting rod 42 and the horizontal arm 41, with the elastic force exerted on the connecting rod 42 by the elastic element 43 pointing downwards. The edge-sealing wheel 45 is located at the lower end of the connecting rod 42. The upper end of the connecting rod 42 is connected via a transmission... The moving part 48 is connected to the foot pedal 484 located at the bottom of the workbench 1. The foot pedal 484 is equipped with a return spring. The transmission part 48 includes a first transmission rod 481 and a second transmission rod 482. One end of the first transmission rod 481 is hinged to one end of the foot pedal 484 that moves up and down with the foot pedal, and the other end is hinged to the lower end of the second transmission rod 482. The upper end of the second transmission rod 482 is hinged to the upper end of the connecting rod 42. A hinge seat 483 is fixed on the bracket 2. The hinge seat 483 is connected to the middle section of the first transmission rod 481 as a lever fulcrum.

[0025] When the operator steps on the foot pedal 484, one end of the foot pedal descends and drives one end of the first transmission rod 481 to descend. Then, the lower end of the second transmission rod 482 swings downward, and the upper end of the second transmission rod 482 drives the upper end of the connecting rod 42 to rise upward, thereby lifting the pressure wheel 45.

[0026] The elastic element 43 includes a lifting block 433 fixedly mounted on the connecting rod 42. Vertical guide rods 431 pass through both ends of the lifting block 433 and slide up and down along the guide rods 431. Both ends of the guide rods 431 are fixed inside the cross arm 41. A spring 432 is sleeved on the guide rods 431, with its end abutting between the lifting block 433 and the upper wall of the cross arm 41. The spring 432 is in a pre-compressed state. In its natural state, the elastic force of the spring 432 pushes the lifting block 433 to slide downward, so that the pressure wheel 45 presses tightly against the lower roller 46.

[0027] The worktable 1 is provided with a lower roller 46 corresponding to the pressing roller 45. The lower roller 46 and the pressing roller 45 cooperate to form a clamping structure. When the canvas passes between the two, it is pressed together. The lower roller 46 is driven by a reduction motor, and the upper edge of the lower roller 46 protrudes from the surface of the worktable 1.

[0028] The implementation principle of a novel edge-sealing machine according to embodiment 2 of the utility model is as follows: Based on embodiment 1 of the utility model, when the first end of the canvas is conveyed to the front side of the edge-sealing device 4, the foot pedal 484 is lightly pressed to lift the edge-sealing wheel 45. After the canvas is completely inserted between the edge-sealing wheel 45 and the lower roller 46, the foot pedal 484 is released, and the edge-sealing wheel 45 is reset under the elastic force of the elastic element 43. The elastic element 43 drives the edge-sealing wheel 45 to press down, and the edge-sealing of the canvas is completed by adjusting the pressure. The foot pedal 484 controls the lifting and lowering of the edge-sealing wheel 45, which frees the hands to focus on the conveying of the canvas, reduces operating errors and reduces the input of labor costs.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
