Description

Technical Field

[0001] The present invention relates to the technical field of cable tie machine mechanisms, in particular to a side-cutting feeding mechanism for a cable tie machine. Background Art

[0002] At present, cable tie suppliers generally provide two types of cable ties, one is a single cable tie, and the other is a cable tie row. The connection method of this cable tie row is through the sprue material at the upper and lower ends of the cable tie; manufacturers who purchase single cable ties generally bundle the products manually or use automatic cable tie machines; when using automatic cable tie machines, first use a vibration plate to sort multiple single cable ties and feed them to the bundling mechanism in the automatic cable tie machine to complete the bundling of the products; manufacturers who purchase cable tie rows first use cable tie shearing equipment to cut the cable tie row into individual cable ties, and then multiple single cable ties are adjusted in position on the vibration plate and transferred to the feeding mechanism in the cable tie bundling machine through a conveyor line. The cable tie is bundled through the front and rear claws in the feeding mechanism, and the front end of the cable tie is driven by the front claw to hook into the buckle part at the rear end of the cable tie to complete the bundling. This production method has the advantage of high efficiency compared to manual bundling. However, the feeding mechanism installed in the cable tie bundling machine currently on the market cannot cut the cable tie rows. The cable tie bundling machine also needs to be used in conjunction with cable tie shearing equipment, a vibrating plate, and a conveyor line. The production cost is high and the space occupied is large. In addition, the tightening of the cable tie during bundling is only driven by the front claw. There are limitations for cable ties of different lengths and sizes. The front claw components need to be adjusted before production, which increases production time. Therefore, it is necessary to develop a feeding mechanism that is suitable for different environments, can be used with automatic bundling machines, and integrates cutting, feeding, and bundling to solve the above problems.

[0035] The tensioning mechanism 400 includes a gear 401 meshing with each other, a gear 401 driving device drivingly connected to the gear 401, and a tensioning disk 402 connected to the meshing gear 401. The gear 401 is disposed in the gear 401 mounting slot 114 of the fixed block 103. The meshing portion of the tensioning disk 402 is located above the end of the rear claw slot 108. The gear 401 driving device is a motor, which is disposed at the rear end of the fixed block 103.

[0036] The shearing mechanism 500 includes an assembly block 501 and a scissor blade 502. The assembly block 501 is disposed above the rear claw 101 and is penetrated by a bundling slot 503 for allowing the cable tie to pass through, and is flanked by a blade slot 504.

The scissor blade 502 can be adjusted to suit cable ties of different sizes and specifications.

[0037] Working principle: First, the cable tie row is pushed into the clamping plate 102 by manual or external feeding mechanism, and then the reciprocating feeding mechanism 200 drives the Z-axis cylinder 203 and the first X-axis cylinder 209 in sequence, driving the cable tie feeding claw 201 to clamp the cable tie at the front end of the cable tie row and push it forward. After the pushing is completed, the cable tie feeding claw 201 is lifted and reset to the initial position, and then cyclically lowered, pushed the cable tie forward, lifted, and reset, so that the cable tie row can be transported forward through the gap, and then the front end of the cable tie row enters under the work station slot 107, and When the nozzle material 3 of the cable tie row corresponds to the nozzle material trough 304, the cutter driving device 302 drives the cutter 301 to cut the material downward, cuts off the nozzle material 3 of the cable tie row, and the nozzle material 3 falls down along the nozzle material trough 304. When the cutting part 305 cuts the nozzle material 3, the sheets on the left and right sides of it clamp the cable tie to prevent it from moving out of position during cutting, and as the cutter 301 moves downward, the pressing part 306 presses the cable tie to further prevent the cable tie from moving out of position, and then the cutter 301 resets and moves upward, and the reciprocating feeding mechanism 200 continues The rear strap row is continuously driven forward, and the single strap with the nozzle material 3 cut off at the front side of the strap row is pushed into the second strap passing space 105, and then the pushing cylinder 111 slides the single strap forward along the second strap passing space 105 until the buckle portion 2 at the rear end of the strap is supported by the limit block 110, at this time, the front end of the strap enters the front claw chute 109 of the front claw 100, and then the front claw cylinder 112 drives the front claw 100 to swing forward, and the front end of the strap is driven by the front claw 100 and moves along the rear claw 10 1 enters the buckle part 2 of the cable tie and continues to rise, and then enters the meshing part of the tensioning disk 402 along the bundling slot 503 in the assembly block 501, and the motor drives the tensioning disk 402 to slide in relative meshing, and pulls the front end of the cable tie to continue tightening. As the tightening continues, the front end of the cable tie gradually approaches the scissor blade 502 of the bundling slot 503, and finally cuts off the excessively long part of the front end of the cable tie. Finally, the front claw cylinder 112 releases the front claw 100, and the tied cable tie falls off outside the mechanism.

[0038] Example 2:

[0039] like Figures 9 to 11As shown, the mechanism in this embodiment is roughly the same as that in the embodiment, except that the fixed block 103, the feeding drive device 202, and the cable tie feeding claw 201; the station slot 107 on the fixed block 103 includes a cutting slot 107A and a feeding slot 107B; the cutting slot 107A corresponds to the position of the cutter 301; the feeding drive device 202 includes a second X-axis cylinder 210 and an articulated mounting block 211; the second X-axis cylinder 210 is fixedly arranged on the front side of the mounting plate 106 and is located above the fixed block 103; the articulated mounting block 211 is arranged on the second The output end of the X-axis cylinder 210 has a hinged mounting slot 212 at its front end; the cable tie feeding claw 201 is hinged to the hinged mounting slot 212, and its front end extends downward from the feeding slot 107B and reaches the first cable tie passing space 104. The front end of the cable tie feeding claw 201 is two fork-shaped sheets, which are flush and parallel to the driving direction of the second X-axis cylinder 210. The rear side of the sheet has an inclined surface 201A that tilts from low to high and from outside to inside; and a return spring is also provided on the upper part of the hinge between the cable tie feeding claw 201 and the hinged mounting slot 212.

[0040] Working principle: The working principle is roughly the same as that of the embodiment. The difference is that the feeding drive device 202 in this embodiment uses the rebound of the reset spring instead of the setting of the two stroke direction cylinders in the embodiment. The specific action is that when feeding the cable tie row, the front end of the cable tie feeding claw 201 pushes the cable tie row into the work station slot 107, and then the cutter 301 moves downward and cuts off the nozzle material 3, and then the clamping part 306 clamps the cable tie, and the second X-axis cylinder 210 drives the cable tie feeding claw 201 to move backward. After the inclined surface 201A on the rear side of the cable tie feeding claw 201 passes through the cable tie, the reset spring is compressed, and the cable tie feeding claw 201 is lifted and slides into the next cable tie. The spring returns to normal state, the cutter 301 resets upward, the cable tie feeding claw 201 pushes forward, and the above steps are repeated.

[0041] The cutters in the side cutting mechanisms in Example 1 and Example 2 both include a cutting portion, the middle portion of which has a sharp edge inclined toward one side or the other, and two fork-shaped sheets on the left and right sides. The middle portion and its left and right sides form a rectangular structure with a downward groove. However, for the function of positioning and cutting the row of cable ties transported by the reciprocating feeding mechanism and cutting them into individual cable ties, the different shapes of the cutting portion are not limited. The rectangular structure formed by the middle portion of the cutting portion and its left and right sides in the present invention is only exemplified as an embodiment, and the shape of the cutting portion can be any geometric shape such as a circle or a triangle.

[0042] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
