Description

Technical Field

[0001] This utility model relates to the field of ceramic tile packaging equipment technology, and in particular to an electric tightening device for ratchet binding. Background Technology

[0002] In the ceramic tile production process, after the tiles are produced, they need to be stacked. After stacking, the entire pile of tiles needs to be packaged and bundled. The current method of packaging tiles involves manually wrapping straps around the perimeter of the tiles and manually tightening the straps to secure them, which is inefficient. Utility Model Content

[0003] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide an electric tightening device for a ratchet binder.

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

[0005] An electric tightening device for a ratchet strapping machine includes a feeding assembly storing a strap roll for strapping products, a strap insertion assembly disposed on one side of the feeding assembly, and a strap tightening assembly for tightening the strap. The strap tightening assembly includes a bearing housing, a rotary motor, a cable tie ratchet, a backstop, and a retainer. Both ends of the cable tie ratchet are bearing-connected to the bearing housing, and the output shaft of the rotary motor is fixedly connected to one end of the cable tie ratchet. The backstop is disposed on the bearing housing and engages with the cable tie ratchet. The retainer is disposed on one side of the cable tie ratchet, and one end of the strap is fixed to the retainer. The cable tie ratchet has a through slot along its length, and the strap insertion assembly is used to insert the other end of the strap into the slot, with the strap wrapped around the periphery of the product.

[0006] By adopting the above technical solution, one end of the strap is fixed to the card seat. After the tiles are stacked, the strap insertion assembly inserts the other end of the strap into the slot of the wire harness ratchet. The rotating motor drives the wire harness ratchet to rotate, thereby wrapping the strap around the circumference of the wire harness ratchet, so that the strap wrapped around the tiles is tightened for bundling and packaging. The automated bundling operation is more efficient and the strap binding is more secure.

[0007] Furthermore, the anti-reverse component includes a toothed plate and a fixing frame. One end of the fixing frame is fitted onto the wire harness ratchet, and the fixing frame is provided with a sliding groove. One end of the toothed plate is slidably disposed within the sliding groove. A first gear is provided at the end of the toothed plate near the wire harness ratchet, and a second gear is provided on the circumferential side of the outer surface of the wire harness ratchet. The first gear and the second gear mesh with each other to prevent the wire harness ratchet from reversing, thereby improving the efficiency and safety of binding.

[0008] Furthermore, the height of the end of the slide near the wire harness ratchet is lower than the height of the other end of the slide, which facilitates the toothed plate to return to its initial position under its own weight to engage with the wire harness ratchet, thereby improving work efficiency and saving costs.

[0009] Furthermore, the retaining bracket includes two connecting pieces, a connecting rod, and a pressing piece. One end of each of the two connecting pieces is fitted onto the cable tie ratchet, and the other end of each of the two connecting pieces is fixed to the bearing seat. A retaining groove is disposed between the two connecting pieces, and the connecting rod is disposed between the other ends of the two connecting pieces. The pressing piece is disposed on the side of each of the two connecting pieces away from the bearing seat. The gap between the pressing piece and the connecting rod forms a fixing groove. One end of the strap passes through the fixing groove and is pressed between the pressing piece and the side of the bearing seat, improving the fixing efficiency.

[0010] Furthermore, a protective cover and a strap insertion sensor are provided between the pressing plate and the bearing seat. The strap insertion sensor is located below the slot, and the protective cover covers the outer periphery of the strap insertion sensor, facilitating automatic detection of whether the strap is inserted correctly and improving the efficiency of the binding operation. The protective cover is located between the strap insertion sensor and the pressing plate, and the end of the strap is fixed between the protective cover and the pressing plate, resulting in a more compact structure.

[0011] Furthermore, the strap insertion assembly is positioned above the cable tie ratchet. The strap insertion assembly includes a strap insertion cylinder and an insertion plate. The output shaft of the strap insertion cylinder is connected to the insertion plate, which is located above the slot. The insertion plate is used to press the other end of the strap into the slot, enabling automated operation and higher efficiency.

[0012] Furthermore, the insertion assembly also includes a fixing plate, a limiting frame, and a limiting rod. One end of the fixing plate is connected to the output shaft of the insertion cylinder, one end of the limiting frame is connected to the other end of the fixing plate, and the limiting rod is disposed within the limiting frame. The limiting frame has an opening facing the other end of the strap, and the length of the other end of the limiting frame is greater than the length of the end of the limiting frame closest to the insertion cylinder. The insertion piece is fixed to the fixing plate, and the lower end of the insertion piece is disposed below the limiting rod, which can limit the displacement of the strap, prevent misalignment during strap insertion, and improve the accuracy and efficiency of strap insertion.

[0013] Furthermore, the feeding assembly includes a material seat and a damping shaft. The material seat has an open storage groove. One end of the damping shaft passes through the material seat and is located in the storage groove. The strap roll is fitted onto the end of the damping shaft located in the storage groove, which can prevent the strap roll from unraveling and improve packaging efficiency.

[0014] Furthermore, the tape feeding assembly also includes a spring, a clamping seat, two pressure plates, and a clamping cylinder. The clamping seat is fitted around the periphery of one end of the damping shaft located outside the material seat, and one end of the clamping seat is fixed to the material seat. The spring is fixed to the damping shaft and located inside the clamping seat. The clamping cylinder is located on the side of the material seat away from the clamping seat, and the output shaft of the clamping cylinder passes through the material seat and is located in the slot. One of the pressure plates is connected to the clamping cylinder, and the other pressure plate is located on the damping shaft. The two pressure plates clamp the tape roll, improving the compatibility of the tape feeding assembly to accommodate tapes of different sizes.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention uses a strap that is fixed at one end to a card holder. After the tiles are stacked, the strap insertion assembly inserts the other end of the strap into the slot of the wire harness ratchet. The rotating motor drives the wire harness ratchet to rotate, thereby wrapping the strap around the circumference of the wire harness ratchet, which tightens the strap wrapped around the tiles for bundling and packaging. This automated bundling operation is more efficient and the straps are more secure. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-7 The embodiments of this utility model will be described in further detail below.

[0030] The ratchet binding device with electric tightening mechanism is installed on the binding machine 1. Each binding machine 1 has at least one set, and the required number is selected based on actual needs. For example... Figure 1 , Figure 2, Figure 3 As shown, it includes a feeding assembly 2 containing a roll of strapping for binding products, a strap insertion assembly 3 disposed on one side of the feeding assembly 2, and a binding and tightening assembly 4 for tightening the strapping 5. The binding and tightening assembly 4 includes a bearing housing 41, a rotary motor 42, a cable tie ratchet 43, a backstop 44, and a retainer 45. The two ends of the cable tie ratchet 43 are bearing-connected to the bearing housing 41, and the output shaft of the rotary motor 42 is fixedly connected to one end of the cable tie ratchet 43. The backstop 44 is disposed on the bearing housing 41 and engages with the cable tie ratchet 43. The retainer 45 is disposed on one side of the cable tie ratchet 43, and one end of the strapping 5 is fixed to the retainer 45. The cable tie ratchet 43 has a through groove 431 along its length direction, and the strap insertion assembly 3 is used to insert the other end of the strapping 5 into the groove 431, so that the strapping 5 is wrapped around the periphery of the product.

[0031] One end of the strap 5 is fixed to the card holder 45. After the tiles are stacked, the strap insertion assembly 3 inserts the other end of the strap 5 into the slot 431 of the wire harness ratchet 43. The rotating motor 42 drives the wire harness ratchet 43 to rotate, thereby wrapping the strap 5 around the circumference of the wire harness ratchet 43, so that the strap 5 wrapped around the tiles is tightened for binding and packaging. The automated binding operation is more efficient and the strap 5 is more secure.

[0032] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 4 The anti-reverse component 44 includes a toothed plate 441 and a fixing frame 442. One end of the fixing frame 442 is fitted onto the wire harness ratchet 43, and the fixing frame 442 is provided with a sliding groove 443. One end of the toothed plate 441 is slidably disposed within the sliding groove 443. A first gear is provided at the end of the toothed plate 441 near the wire harness ratchet 43, and a second gear is provided on the circumferential side of the outer surface of the wire harness ratchet 43. The first gear and the second gear are meshed and connected to prevent the wire harness ratchet 43 from reversing, thereby improving the efficiency and safety of binding. The structures of the first gear and the second gear are not shown in the figure.

[0033] Preferably, the height of the end of the slide groove 443 near the wire harness ratchet 43 is lower than the height of the other end of the slide groove 443, so that the toothed plate 441 is inclined downward, which makes it easier for the toothed plate 441 to return to the initial position under its own weight to engage with the wire harness ratchet 43, thereby improving work efficiency and saving costs.

[0034] In some embodiments, please refer to Figure 2 , Figure 3The retainer 45 includes two connecting pieces 451, a connecting rod 452, and a pressing piece 453. One end of each connecting piece 451 is fitted onto a wire harness ratchet 43, and the other end of each connecting piece 451 is fixed to a bearing seat 41. A slot 431 is provided between the two connecting pieces 451, and the connecting rod 452 is provided between the other ends of the two connecting pieces 451. A pressing piece 453 is provided on the side of each connecting piece 451 away from the bearing seat 41. The gap between the pressing piece 453 and the connecting rod 452 forms a fixing groove. One end of the strap 5 passes through the fixing groove and is pressed between the pressing piece 453 and the side of the bearing seat 41, improving the fixing efficiency.

[0035] To improve detection efficiency and the insertion status of the strap 5, a protective cover and a strap insertion sensor 46 are provided between the pressing plate 453 and the bearing seat 41. The strap insertion sensor 46 is located below the slot 431, and the protective cover is placed on the outer periphery of the strap insertion sensor 46, facilitating automatic detection of whether the strap 5 is inserted in place and improving the efficiency of the binding operation. The protective cover is located between the strap insertion sensor 46 and the pressing plate 453, and the end of the strap 5 is fixed between the protective cover and the pressing plate 453, resulting in a more compact structure.

[0036] In some embodiments, please refer to Figure 1 , Figure 5 Figure 7 shows that the strap insertion assembly 3 is positioned above the cable tie ratchet 43. The strap insertion assembly 3 includes a strap insertion cylinder 31 and a insertion plate 32. The output shaft of the strap insertion cylinder 31 is connected to the insertion plate 32, which is located above the slot 431. The insertion plate 32 is used to press the other end of the strap 5 into the slot 431, enabling automated operation and higher efficiency.

[0037] To ensure the strap 5 remains aligned with the slot 431 during pressing, the strap insertion assembly 3 also includes a fixing plate 34, a limiting frame 33, and a limiting rod 35. One end of the fixing plate 34 is connected to the output shaft of the strap insertion cylinder 31, one end of the limiting frame 33 is connected to the other end of the fixing plate 34, and the limiting rod 35 is disposed within the limiting frame 33. The limiting frame 33 has an opening facing the other end of the strap 5, and the length of the other end of the limiting frame 33 is greater than the length of the end of the limiting frame 33 closest to the strap insertion cylinder 31. The insertion piece 32 is fixed to the fixing plate 34, and the lower end of the insertion piece 32 is positioned below the limiting rod 35, which can limit the displacement of the strap 5, prevent misalignment during strap insertion, and improve the accuracy and efficiency of strap insertion.

[0038] In some embodiments, please refer to Figure 1 , Figure 5 , Figure 6The feeding assembly 2 includes a material holder 21 and a damping shaft 22. The material holder 21 is provided with an open storage groove 23. One end of the damping shaft 22 passes through the material holder 21 and is located in the storage groove 23. The strap roll is fitted into the end of the damping shaft 22 located in the storage groove 23, which can prevent the strap roll from unraveling and improve packaging efficiency.

[0039] To accommodate and clamp different sizes of strap rolls to prevent loosening, the strap feeding assembly 2 also includes a spring 24, a clamping seat 25, two pressure plates 26, and a clamping cylinder 27. The clamping seat 25 is fitted around the periphery of one end of the damping shaft 22 located outside the material holder 21, and one end of the clamping seat 25 is fixed to the material holder 21. The spring 24 is fixed to the damping shaft 22 and located inside the clamping seat 25. The clamping cylinder 27 is located on the side of the material holder 21 away from the clamping seat 25, and its output shaft passes through the material holder 21 and is located in a slot 431. One pressure plate 26 is connected to the clamping cylinder 27, and the other pressure plate 26 is located on the damping shaft 22. The two pressure plates 26 clamp the strap roll, improving the compatibility of the strap feeding assembly 2 to accommodate different sizes of straps 5.

[0040] During operation, the operator manually pulls the strap 5 on the insertion assembly 3 along the side of the stacking frame away from the binding and tightening assembly 4 to the position of the card seat 45, and fixes the end of the strap 5 to the card seat 45. Then, the stacker crane stacks the tiles onto the stacking frame. After the tiles are stacked, the control system controls the insertion assembly 3 to move above the card slot 431. The insertion cylinder 31 drives the insertion piece 32 and the limiting rod 35 to press down on the other end of the strap 5. The insertion piece 32 moves into the card slot 431 and inserts the end of the strap 5 into the card slot 431. After the insertion sensor 46 detects that the strap 5 is inserted in place, the insertion cylinder 31 drives the insertion piece 32 and the limiting rod 35 to rise to the initial position. The rotary motor 42 starts, and the output shaft of the rotary motor 42 drives the wire harness ratchet 43 to rotate. Since the other end of the strap 5 is fixed in the slot 431, the strap 5 is continuously wrapped around the circumference of the wire harness ratchet 43 as the ratchet 43 rotates, thereby gradually shortening the length of the strap 5 around the tile until the strap 5 is securely tied, the rotating motor 42 stops rotating, and the binding and packaging is completed.
