Description

Technical Field

[0001] The invention relates to casing machine technology, and in particular to a fault warning device for a casing machine. Background Art

[0002] The tubing machine is a device specially used for shrinking and forming heat shrink tubing. During normal operation, the tubing on the winding roller is released and transported so that it can be sleeved on the outside of the wire, cable or connector to be wrapped, and then heated by a heat source to shrink it and tightly wrap it around the outside of the component to be protected.

[0003] In actual application, the sleeve on the winding roller may be affected by the winding tension during the initial processing and winding process, causing it to partially penetrate into the sleeve of the looser part, resulting in obstruction of the sleeve when it is applied to the sleeve machine, or when the sleeve is obstructed due to uneven tension during the unwinding process and mechanical failure, the continued rotation of the winding roller will rewind the previously released sleeve, so that the winding roller and the driving wheel group simultaneously apply external forces in opposite directions to the sleeve between the two. Under the application of two external forces in opposite directions, the sleeve between the two is gradually stretched and deformed, so that it is not easy to damage the sleeve, and the heat shrink end sleeve cannot be normally sleeved on the outside of the wire, so that the normal operation of the sleeve machine is hindered. However, the existing sleeve machine equipment lacks relevant mechanisms for warning of faults at the winding roller. Usually, the staff will be warned only when the heat shrink end cannot work normally. When a fault occurs at the winding roller, the machine has to be stopped for fault maintenance, which affects the normal operation efficiency of the sleeve machine. Summary of the invention

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1:

[0035] See also Figure 1-Figure 9 A fault warning device for a two-wood casing machine includes a machine body 1, a wire wheel 2 with a wire feed groove on the surface is provided on the machine body 1, a plurality of hot air holes are provided inside the wire feed groove, a driving wheel group 3 is provided on the machine body 1, and the driving wheel group 3 is used to transport the casing, a placement cavity is provided inside the machine body 1, a winding roller 4 is rotatably connected inside the placement cavity, the winding roller 4 is driven by a motor, casing is wound on the winding roller 4, a vertical groove connected to the placement cavity is provided on the machine body 1, and an end of the casing away from the winding roller 4 passes through the vertical groove and extends to the driving wheel group 3;

[0036] It should be supplemented that a cutting unit and a pushing unit are also installed on the body 1 and are located between the wiring wheel 2 and the driving wheel group 3. The cutting unit is used to cut off the sleeve after it is transported to the specified position, and the pushing unit is used to push the cut short sleeve after the sleeve is partially cut off, so that it enters the wire feed groove on the wiring wheel 2 and is sleeved on the outside of the wire to be processed, so that the hot air hole can output hot air flow to heat it, so that it shrinks and is stably sleeved on the surface of the wire.

[0037] A support plate 5 is installed inside the placement cavity, and an early warning mechanism 6 is arranged on the support plate 5. The early warning mechanism 6 includes two support plates 61 symmetrically fixedly connected to the top of the support plate 5, and a driving wheel 62 is rotatably connected between the two support plates 61, and the driving wheel 62 is driven by a motor. Guide grooves 63 are opened on the surfaces of the two support plates 61, and a slider 64 is slidably connected to the inner side of the guide groove 63. The outside of the slider 64 is rotatably connected to a driven wheel 65 corresponding to the driving wheel 62. The slider 64 is fixedly connected to the bottom end bracket of the inner wall of the guide groove 63 with a compression spring 66, and the outside of the slider 64 is fixedly connected to a mounting plate 67, and a bell shell 610 is fixedly installed on the surface of the mounting plate 67. A knocking component 68 is arranged on the outside of the mounting plate 67, and the knocking component 68 is used to knock the bell shell 610. A control component 69 is arranged on the outside of the mounting plate 67, and the control component 69 controls the knocking component 68 to knock the bell shell 610 for early warning.

[0038] In this embodiment, a vertical plate 7 is fixedly connected between the two support plates 61, and a bending tube 8 is rotatably connected to the surface of the vertical plate 7. The bottom end of the bending tube 8 is arranged toward the winding roller 4. A slot 10 is opened on the surface of the vertical plate 7. The sleeve passes through the bending tube 8 and the slot 10 in turn, and passes between the driving wheel 62 and the driven wheel 65. The driving wheel 62 rotates to transport the sleeve.

[0039] It should be added that the wire feeding speed of the driving wheel 62 and the driving wheel group 3 is consistent with the wire unwinding speed of the winding roller 4, so that the conveying of the casing can always remain balanced.

[0040] In this embodiment, the striking assembly 68 includes an annular plate 681 fixedly connected to the surface of the mounting plate 67, a notch 682 is provided on the side of the annular plate 681 close to the bell housing 610, a rotating wheel 683 is rotatably connected to the surface of the mounting plate 67, a plurality of straight grooves are equidistantly provided in the interior of the rotating wheel 683 in the shape of a circular ring, a striking rod 684 is slidably connected to the inner side surface of the straight groove, a return spring 685 is fixedly connected between the striking rod 684 and the inner wall of the straight groove, when the striking rod 684 rotates to the position of the notch 682, the return spring 685 drives the striking rod 684 to move and strike the bell housing 610.

[0041] In this embodiment, arc segments 686 are symmetrically provided on both sides of the driving rod 684 away from one end of the return spring 685 , and the inner wall of the notch 682 is provided with a guide arc surface 687 corresponding to the arc segment 686 .

[0042] In this embodiment, the control assembly 69 includes a connecting wheel 691 coaxially fixedly connected to the driven wheel 65, the interior of the connecting wheel 691 is provided with a plurality of short grooves equidistantly in an arc shape, the inner side surface of the short groove is slidably connected with a control block 692, a connecting spring 693 is fixedly connected between the control block 692 and the inner wall of the short groove, the outer side of the rotating wheel 683 is coaxially fixedly connected with a control wheel 694, and the side surface of the control wheel 694 is provided with a plurality of auxiliary blocks 695 equidistantly in an arc shape;

[0043] The control block 692 includes a first arc surface 6921 disposed on the surface, and a first straight surface 6922 is disposed on the surface of the control block 692. The first arc surface 6921 and the first straight surface 6922 are disposed on a side opposite to the end of the control block 692.

[0044] The auxiliary block 695 includes a second arc surface 6951 disposed on the surface thereof. The surface of the auxiliary block 695 is provided with a second straight surface 6952 . The second arc surface 6951 and the second straight surface 6952 are disposed on a side opposite to the end of the auxiliary block 695 .

[0045] Specifically, the position and specifications of the second arc surface portion 6951 correspond to those of the first arc surface portion 6921, the position and specifications of the second straight surface portion 6952 correspond to those of the first straight surface portion 6922, and the friction resistance value between the driving wheel 62 and the driven wheel 65 and the casing in the normal conveying state is greater than the relative sliding friction resistance value between the first arc surface portion 6921 and the second arc surface portion 6951, and the relative sliding friction resistance value between the first arc surface portion 6921 and the second arc surface portion 6951 is less than the sliding friction resistance value between the striking rod 684 and the inner wall of the ring plate 681.

[0046] It should be further explained that, in the normal conveying state of the casing, the driven wheel 65 rotates with the movement of the casing. During this process, the driven wheel 65 will drive the connecting wheel 691 to rotate, and the rotation of the connecting wheel 691 drives the control block 692 to rotate, so that there is a relative sliding force between the first arc surface 6921 on the control block 692 and the second arc surface 6951 on the auxiliary block 695, and under the push of this force, the control block 692 can move into the short groove, so that the first arc surface 6921 and the second arc surface 6951 can slide relative to each other, so that the control block 692 cannot drive the auxiliary block 695 to rotate synchronously; when the driven wheel 65 rotates in the opposite direction, the first straight surface 6922 directly abuts against the second straight surface 6952, so that the rotation of the control block 692 can push the auxiliary block 695 to overcome the relative sliding friction resistance between the striking rod 684 and the inner wall of the ring plate 681, thereby driving the rotating wheel 683 to rotate.

[0047] During normal operation, the winding roller 4, the driving wheel group 3 and the active wheel 62 synchronously transport the casing. When the casing on the winding roller 4 is compressed and cannot be transported normally, the continued rotation of the winding roller 4 will gradually reel up the released casing. At this time, the active wheel 62 and the winding roller 4 apply external forces in opposite directions to the casing between them. Since the winding roller 4 directly reels the casing, and the active wheel 62 only transports it through the sliding friction resistance between the casing and the casing, the casing between the two will move toward the direction of the winding roller 4 and drive the driven wheel 65 to rotate in the opposite direction. The reverse rotation of the driven wheel 65 drives the connecting wheel 691 to rotate in the opposite direction, so that the casing on the control block 692 The first straight surface portion 6922 directly contacts the second straight surface portion 6952 on the auxiliary block 695, so that the control block 692 can drive the auxiliary block 695 to rotate as the connecting wheel 691 rotates, and the auxiliary block 695 can drive the control wheel 694 to rotate synchronously when rotating, so that the rotating wheel 683 can overcome the sliding friction resistance between the striking rod 684 and the inner wall of the ring plate 681 to rotate, and drive the striking rod 684 to rotate. When the striking rod 684 rotates to the notch 682, under the action of the rebound force of the return spring 685, the striking rod 684 moves toward the bell housing 610 and collides with it, so that the bell housing 610 emits a crisp metallic sound, thereby providing a fault warning to the surrounding staff;

[0048] When the striking rod 684 rotates until the circular arc segment 686 contacts the guiding arc surface 687, under the guiding action between the two, the striking rod 684 can overcome the rebound force of the reset spring 685 and move toward the inside of the straight groove, thereby not hindering the rotation of the rotating wheel 683, so that the striking rod 684 can continuously impact the bell housing 610, so that the warning sound can continue to be emitted.

[0049] Embodiment 2:

[0050] See also Figure 4-Figure 5 This embodiment provides a technical solution based on the above embodiment: a warning mechanism 9 is arranged on the support plate 5, and the warning mechanism 9 includes a support seat 91 installed on the top of the support plate 5, a bearing groove 92 is opened on the top of the support seat 91, a photoelectric sensor 93 is arranged inside the support seat 91, a reserved section 94 is arranged between the driving wheel group 3 and the driving wheel 62, and the reserved section 94 is placed inside the bearing groove 92, and a controller 95 and a buzzer 96 are installed at the bottom of the support plate 5.

[0051] In this embodiment, the photoelectric sensor 93 is disposed at the middle position of the bottom end of the inner wall of the bearing groove 92 , and the reserved section 94 located at the bottom end of the inner wall of the bearing groove 92 can shield the photoelectric sensor 93 .

[0052] Specifically, the controller 95 is used to receive the data information detected by the photoelectric sensor 93, and control the buzzer 96 to start or maintain a standby state according to the received data information. When the reserved section 94 is separated from the bottom of the inner wall of the supporting groove 92, the controller 95 receives the data information transmitted by the photoelectric sensor 93 and controls the buzzer 96 to start.

[0053] During the early warning process, the winding roller 4 continuously rewinds the sleeve, so that the length of the reserved section 94 gradually decreases, and as the length of the reserved section 94 gradually decreases, it gradually separates from the bottom surface of the supporting groove 92, making it unable to continue to block the photoelectric sensor 93, so that the controller 95 controls the buzzer 96 to emit a buzzing sound, which can alert the surrounding or distant staff.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
