Description

Technical Field

[0001] The invention relates to the technical field of carton production, and in particular to a bundling device for carton production. Background Art

[0002] With the development of the automated packaging industry, automatic strapping machines have been widely used in the food, medicine, electronic machinery and other industries, and in large quantities and on a wide range of applications. Strapping machines are machines that use strapping tape to wrap around products or packages, then tighten and melt or knot the strapping tape joints through thermal effects.

[0003] The Chinese patent document with the authorization announcement number CN108706114B discloses a carton baler for packaging with multiple strapping straps, including a strapping machine, a conveyor belt and a carton limiting device; the strapping machine is composed of a lower support platform and an upper frame; the conveyor belt is arranged on the support platform and passes through the frame; the carton limiting device includes a pair of horizontal support plates; the upper end surface of the frame is formed with a pair of front-to-back symmetrical upper support plates; a pair of horizontal support plates are respectively slidably arranged on the opposite end surfaces of the pair of upper support plates; a pair of central support rods are respectively arranged to rotate synchronously between the left parts of the pair of horizontal support plates; telescopic support rods are respectively arranged at both ends of the central support rod; and a limiting roller is pivotally connected between the pair of telescopic support rods on the same side. This patent document enables the carton to be tied with multiple straps, adapting to cartons of different sizes and with controllable gaps between multiple strapping straps.

[0004] In the above technical solution, multiple strapping straps are used to strap cartons of different sizes by setting strapping machines, transmission belts, etc. However, when strapping the boxes, there is a certain elasticity between the multiple stacked box cardboards. If the strapping force is weak, the boxes may be scattered during transportation. If the strapping force is strong, the top and bottom cardboards may be damaged. At the same time, when strapping, if the stacked cartons are tilted, the side of the cardboard will contact the straps, which will also cause the cartons to be damaged. Summary of the invention

[0005] The present invention provides a bundling device for carton production, aiming to solve the problem in the related art that cardboard is easily damaged when bundling cartons.

[0006] A bundling device for carton production comprises: a strapping machine, a conveying device, clamping plates arranged on the upper and lower sides of the conveying device, a driving member installed between the two clamping plates to make the upper clamping plate close to the lower clamping plate, the top of the lower clamping plate is flush with the top of the conveying device, and the two clamping plates press the cartons on the conveying device when they approach each other; storage boxes are arranged on both sides of each conveying device, V-shaped pads are evenly distributed in the storage boxes, electric telescopic rods that can be telescoped forward and backward are installed on the clamping plates, and a connecting component is provided between the electric telescopic rod and the V-shaped point pads so that the electric telescopic rod is connected to the V-shaped pads when it is extended into the storage box, and the side edges of the V-shaped pads are in contact with multiple cartons when the V-shaped pads in the front and rear directions approach each other, and when the electric telescopic rod is shortened to the shortest distance, the electric telescopic rod is out of contact with the V-shaped pads, and the strapping machine moves along the conveying direction of the conveying device to strap the cable tie on the V-shaped pads.

[0007] The effect is that by setting the V-shaped pad, the strapping machine will strap the cable tie on the V-shaped pad to avoid damage to the cartons during strapping. During strapping, the V-shaped pad can contact the sides of multiple cartons so that the strapping force of the V-shaped pad is applied to the sides of multiple cartons to avoid bending of the cartons.

[0008] Preferably, the V-shaped pad includes plate one and plate two, plate one is horizontally arranged, plate two is inclined, and the angle between plate one and plate two is an obtuse angle, so as to avoid contact between the cable tie and the carton during bundling.

[0009] Preferably, a positioning groove is provided on the V-shaped pad, and the strapping machine straps the cable tie in the positioning groove during strapping to prevent the cable tie from falling off the V-shaped pad after strapping.

[0010] Preferably, the connecting assembly includes a connecting block fixedly arranged at the movable end of the electric telescopic rod and a connecting groove opened on the V-shaped pad. An elastic sheet is arranged on the top of the connecting block. When the connecting block enters the connecting groove, the elastic sheet is compressed and the connecting block and the connecting groove are connected together by the elastic force of the elastic sheet, so that the electric telescopic rod can drive the V-shaped pad onto the carton and can detach the V-shaped pad from the electric telescopic rod.

[0011] Preferably, the driving member is an electric lifting rod, which is installed on the conveying device, and the movable end of the electric lifting rod is connected to the clamping plate above; the clamping plate is driven to rise and fall by the electric lifting rod.

[0012] Preferably, an opening corresponding to the electric telescopic rod is provided on the storage box, and a push spring is provided inside the storage box for pushing the V-shaped pad in the storage box to the opening; so that the V-shaped pad can move all the way to the opening so that the electric telescopic rod is connected to the V-shaped pad.

[0013] Preferably, the conveying device comprises a support platform and an electric conveying roller, and the conveying device is provided with at least two breakpoints, so that the cable tie passes through the breakpoints of the conveying device and is tied to the carton.

[0014] Preferably, an electric slide rail is provided at the bottom of the strapping machine, and the electric slide rail is parallel to the conveying direction of the conveying device. When the electric telescopic rod drives the V-shaped pad onto the carton and presses the carton through two clamping plates, the strapping machine moves along the electric slide rail to a position corresponding to the V-shaped pad; the strapping machine is moved by the electric slide rail.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. When bundling cartons, after the cartons are transported to a suitable position by the conveying device, the electric telescopic rod extends into the storage box and brings the V-shaped pad to fit the carton, and then drives the clamping plate to move downward through the driving part, and presses the carton through the clamping plate. When the strapping machine moves, the strapping tie is tied to the V-shaped pad to prevent damage to the carton; 2. The angle between plate one and plate two is an obtuse angle. Plate two can contact multiple inclined cartons when moving toward the carton. When the cable tie is tied to the V-shaped pad, plate two is slightly deformed by force to apply force to the sides of multiple cartons. At the same time, the inclined plate two can prevent the cable tie from contacting the side of the carton and deforming the carton. When the clamping plate drives the V-shaped pad to descend, the inclined setting of plate two can avoid contact with the carton and thus damage the carton. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figure 1-Figure 6 As shown, a bundling device for carton production includes a strapping machine 1, a conveying device 2, clamping plates 3 arranged on the upper and lower sides of the conveying device 2, a storage box 5, a V-shaped pad 6 arranged in the storage box 5, and an electric telescopic rod 7 installed on the clamping plate 3 and telescopic in the front-rear direction; when the cartons are strapped, the cartons are conveyed by the conveying device 2, and after the cartons are conveyed to the specified position, the electric telescopic rod 7 is extended into the storage box 5 and connected with the V-shaped pad 6, and when the electric telescopic rod 7 is contracted, the V-shaped pad 6 is driven to fit with the carton, and then the carton is clamped by the clamping plates 3 approaching each other, and finally the strapping machine 1 is moved to strap the strap on the V-shaped pad 6 to avoid damage to the carton.

[0025] Specifically, the conveying device 2 includes a support platform 21 and an electric conveying roller 22. When bundling cartons, at least two cable ties are used. The corresponding conveying device 2 has at least two breakpoints. When bundling cartons, the cable ties are used to bundle cartons from the breakpoints of the conveying device 2.

[0026] Specifically, the driving member 4 is an electric lifting rod, which is installed on the conveying device 2. The movable end of the electric lifting rod is connected to the clamping plate 3 above. The electric lifting rod drives the clamping plate 3 to move downward and press the carton.

[0027] The connecting assembly 8 includes a connecting block 81 fixedly arranged at the movable end of the electric telescopic rod 7 and a connecting groove 82 opened on the V-shaped pad 6. The outside of the connecting block 81 is wrapped with a rubber layer. When the electric telescopic rod 7 drives the connecting block 81 to extend into the connecting groove 82, the connecting block 81 and the connecting groove 82 are interference fit. When the electric telescopic rod 7 contracts, the V-shaped pad 6 moves with the electric telescopic rod 7 and finally fits on the carton.

[0028] In other embodiments of the present invention, an elastic sheet 83 is provided on the top of the connecting block 81. When the connecting block 81 enters the connecting groove 82, the elastic sheet 83 is compressed and the connecting block 81 and the connecting groove 82 are connected together by the elastic force of the elastic sheet 83. When the carton bundling is completed, the electric telescopic rod 7 shrinks to the shortest distance. At this time, the connecting block 81 is disengaged from the connecting groove 82, that is, the electric telescopic rod 7 is out of contact with the V-shaped pad 6.

[0029] In a specific embodiment of the present invention, the V-shaped pad 6 includes a plate 1 61 and a plate 2 62. The angle between the plate 1 61 and the plate 2 62 is an obtuse angle. In a preferred embodiment of the present invention, the angle between the plate 1 61 and the plate 2 62 is 100 degrees. If the conveying device 2 produces a certain deviation when conveying the carton, the plate 2 62 is arranged in an inclined state. When the carton is bundled, the plate 2 62 can prevent the cable tie from directly contacting the carton and causing deformation of the carton. If the plate 1 61 and the plate 2 62 are arranged vertically, the clamping plate 3 will drive the V-shaped pad 6 to descend a certain distance when it descends, thereby causing the plate 2 62 to contact the carton and cause damage to the carton.

[0030] When the conveying device 2 is conveying cartons, vibration, uneven force and other reasons may cause the cartons to shift during the conveying process. When the electric telescopic rod 7 moves on the V-shaped pad 6, the side of the V-shaped pad 6 contacts multiple cartons. When the cable tie is tied on the V-shaped pad 6, the side of the V-shaped pad 6 is exerted with force and may produce a certain deformation. At this time, the side surfaces of multiple cartons are subjected to force, which can evenly share the force applied to the V-shaped pad 6 when the cable tie is tied.

[0031] In a specific embodiment of the present invention, a positioning groove 63 is provided on the V-shaped pad 6. When the strapping machine 1 is strapping, the strapping tie is strapped in the positioning groove 63 to prevent the strapping tie from falling off the V-shaped pad 6 after the cartons are strapped.

[0032] Preferably, the bottom of plate 1 61 is flush with the bottom of the movable end of the electric telescopic rod 7. When the clamping plate 3 at the top moves downward to press the carton, plate 1 61 and the movable end of the electric telescopic rod 7 can simultaneously apply force to the cardboard so that the cardboard is subjected to the same force.

[0033] The storage box 5 is arranged on both sides of the conveying device 2, and the V-shaped pad 6 is arranged in the storage box 5. An opening corresponding to the electric telescopic rod 7 is opened on the storage box 5. When the electric telescopic rod 7 is extended, it extends into the storage box 5 and is connected with the V-shaped pad 6 at the opening and the V-shaped pad 6 is moved out of the storage box 5. A pushing spring 51 is arranged inside the storage box 5. After the V-shaped pad 6 at the opening is taken away, the pushing spring 51 pushes the other V-shaped pads 6 to the opening so that they can be taken when the electric telescopic rod 7 is extended into the storage box 5 again.

[0034] An electric slide rail 9 is provided at the bottom of the strapping machine 1, and the electric slide rail 9 is parallel to the conveying direction of the conveying device 2. When the electric telescopic rod 7 drives the V-shaped pad 6 onto the carton and presses the carton through the two clamping plates 3, the strapping machine 1 moves along the electric slide rail 9 to the position corresponding to the V-shaped pad 6, and the strapping machine 1 is used to tie the cable tie to the V-shaped pad 6.

[0035] Working principle of the present invention: When bundling the cartons, after the cartons are conveyed to a suitable position by the conveying device 2, the electric telescopic rod 7 extends into the storage box 5 and brings the V-shaped pad 6 to fit the carton, and then drives the clamping plate 3 to move downward through the driving member 4, presses the carton through the clamping plate 3, and the strapping machine 1 straps the cable tie on the V-shaped pad 6 when it moves; the angle between the plate 1 61 and the plate 2 62 is greater than 90 degrees, and the plate 2 62 can contact with multiple inclined cartons when it moves toward the carton. When the cable tie is tied to the V-shaped pad 6, the plate 2 62 is slightly deformed by the force applied to the sides of multiple cartons, and at the same time, the inclined plate 2 62 can prevent the cable tie from contacting the side of the carton to deform the carton; when the clamping plate 3 drives the V-shaped pad 6 to descend, the inclined setting of the plate 2 62 can avoid contact with the carton and thus damage the carton.

[0036] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
