Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard box multi-sided slotting device. Background Technology

[0002] Cardboard boxes (English: carton or hard paper case): are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models.

[0003] A search revealed that Chinese Patent No. CN220332112U discloses a multi-sided grooving device for cardboard box processing, belonging to the field of cardboard box technology. The device includes a main body, a horizontal plate fixedly connected to one side of the main body, and a waste collection box fixedly connected to the other side. A drive motor is fixedly welded to the front of the main body via a fixing block. The output end of the drive motor is connected to a first roller via a coupling. A first gear is fixedly connected to one side of the first roller, and a second gear is meshed with the top of the first gear. A hydraulic cylinder is fixedly connected to one side of the top of the horizontal plate, and a push plate is fixedly connected to the telescopic end of the hydraulic cylinder. A limit block is fixedly welded to the other side of the top of the horizontal plate. This device can groove cardboard boxes and collect the waste material after grooving, reducing labor intensity and demonstrating strong practicality.

[0004] The aforementioned device controls the gear rotation through the output of the drive motor, thereby slotting the cardboard box through the push plate. At the same time, the device can collect waste materials, reducing labor intensity. However, in actual use, due to the different types and varying degrees of softness and hardness of cardboard boxes, if there is no device to fix the sides of the cardboard box, the sides of the cardboard box are prone to bending when they come into contact with the slotting device during actual slotting. This will affect the accuracy of slotting and damage the cardboard box, thereby increasing the damage rate of the cardboard box. Utility Model Content

[0005] The purpose of this invention is to provide a multi-sided slotting device for cardboard boxes, which can solve the problem that when the side of the cardboard box comes into contact with the slotting device during actual slotting, it is easy to bend, which will affect the accuracy of slotting and damage the cardboard box, thereby increasing the damage rate of the cardboard box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-sided slotting device for cardboard boxes, comprising: a base and a second telescopic rod, wherein a connector is fixedly installed on the lower side of the outer surface of the second telescopic rod, and two connecting rods are rotatably connected to the outer surface of the connector, and a sliding sleeve is rotatably connected to the other end of each of the two connecting rods, and a sliding rod is slidably fitted inside the two sliding sleeves, and connecting strips are fixedly connected to both sides of the outer surface of the two sliding sleeves, dividing the four connecting strips into two groups, and a horizontal plate is fixedly connected to one end of each group of connecting strips, and a support plate is fixedly installed at both ends of the outer surface of the two horizontal plates.

[0007] In a preferred embodiment, a spring is movably sleeved on the outer surface of the slide rod, and the two ends of the spring are respectively fixedly connected to one side of the two slide sleeves.

[0008] The technical effect of adopting the above-mentioned further solution is that after the slot is opened, the second telescopic rod no longer puts pressure on the lower structure, so the first spring will automatically release its tension, thereby driving the sliding sleeves on both sides to retract, thus releasing the fixation of the carton.

[0009] In a preferred embodiment, a slide rod 2 is slidably disposed within the four support plates, an L-shaped plate is fixedly installed on the lower side of the outer surface of the four slide rod 2, a spring 2 is fixedly connected to the upper side of the outer surface of the slide rod 2, and the other end of the spring 2 is fixedly connected to the upper side of the support plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the slide bar two is slidably set inside the support plate and is connected by the spring two so that it will not be dislodged from the transverse groove. Thus, when the pressure plate squeezes the carton, the support plate will move downward to adapt to the height. Therefore, when the height changes, the sides of the carton can still be supported and fixed.

[0011] In a preferred embodiment, both ends of the slide bar are fixedly equipped with blocking blocks.

[0012] The technical effect of adopting the above-mentioned further solution is that the blocking block can restrict the movement of the sliding sleeve, prevent the sliding sleeve from detaching from the sliding rod one due to excessive movement, and at the same time can effectively reduce the excessive stretching of the spring one, thereby causing the spring one to accelerate fatigue.

[0013] In a preferred embodiment, a cardboard box is placed on the upper side of the outer surface of the platform, a vertical plate is fixedly installed on one side of the outer surface of the platform, and a top plate is fixedly installed on the upper surface of the outer surface of the vertical plate.

[0014] The technical effect of adopting the above-mentioned further solution is that the vertical plate is used to support the entire fixed structure, while the top plate is used to fix the second telescopic rod.

[0015] In a preferred embodiment, rectangular blocks are fixedly installed on both sides of the outer surface of the platform. Trapezoidal grooves are opened on the upper side of the outer surface of the two rectangular blocks, and sliders are movably fitted inside the two sliders.

[0016] The technical effect of adopting the above-mentioned further solution is that the sliders on both sides slide in the trapezoidal groove, thereby enabling the slot opening device to move freely and thus enabling slot opening on multiple sides of the carton.

[0017] In a preferred embodiment, a telescopic rod is fixedly connected to the upper surface of the outer surfaces of the two sliders, and a grooving machine is fixedly installed on the upper surface of the outer surfaces of the two telescopic rods.

[0018] The technical effect of adopting the above-mentioned further solution is that the height of the grooving machine can be adjusted by the telescopic rod, so that grooves can be opened at different positions according to specific conditions.

[0019] In a preferred embodiment, both of the outer surfaces of the two sliding sleeves are movably connected to the lower side of the outer surface of the two sliding sleeves, and the other ends of the two sliding sleeves are rotatably connected to the upper side of the outer surface of the same pressure plate.

[0020] The technical effect of adopting the above-mentioned further solution is that when the telescopic rod 2 moves downward, it will cause the pressure plate to apply pressure to the bottom of the carton, thereby fixing the position of the carton and preventing it from moving, thus facilitating the opening of the carton.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, by controlling the movement of the telescopic rod two, the overall fixing structure moves downward. When the pressure plate contacts the bottom of the carton, the telescopic rod two continues to extend. At this time, the four connecting rods will apply a force to both sides to the two sliding sleeves, thereby enabling the sliding sleeves to push the support plates on both sides to move to both sides of the carton. When the support plates are released to the side of the carton, the telescopic rod two stops working. At this time, the carton has been firmly fixed, and the two sides of the carton are supported by the support plates. Thus, when punching holes later, the side of the carton can be effectively prevented from bending inward due to the inward force of the punching device.

[0023] 2. In use, after the carton is fixed, the slotting machine located on the upper side of the rectangular blocks can be moved by the rectangular blocks fixed on both sides of the platform to simultaneously open slots on different sides of the carton, thereby avoiding multiple manual operations and improving work efficiency.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-4 This utility model provides a technical solution: a multi-sided slotting device for cardboard boxes, including: a base 101 and a telescopic rod 301. A connector 302 is fixedly installed on the lower side of the outer surface of the telescopic rod 301. Two connecting rods 303 are rotatably connected to the outer surface of the connector 302. The other end of each of the two connecting rods 303 is rotatably connected to a sliding sleeve 304. A sliding rod 305 is slidably fitted inside the two sliding sleeves 304. Connecting strips 308 are fixedly connected to both sides of the outer surface of the two sliding sleeves 304, dividing the four connecting strips 308 into two groups. A horizontal plate 309 is fixedly connected to one end of each group of connecting strips 308. Support plates 310 are fixedly installed at both ends of the outer surface of the two horizontal plates 309.

[0032] like Figure 1-4As shown, a spring 306 is movably sleeved on the outer surface of the slide rod 305. The two ends of the spring 306 are respectively fixedly connected to one side of the two slide sleeves 304. After the slot is opened, the telescopic rod 301 no longer puts pressure on the lower structure, so the spring 306 will automatically release the tension, thereby driving the slide sleeves 304 on both sides to retract, thus releasing the fixation of the carton 104.

[0033] like Figure 1-4 As shown, slide rods 311 are slidably arranged inside the four support plates 310. L-shaped plates 312 are fixedly installed on the lower side of the outer surface of the four slide rods 311 and connected by springs 314 to prevent them from disengaging from the transverse groove. The slide rods 311 are slidably arranged inside the support plates 310, so that when the pressure plate 313 squeezes the carton 104, the support plates 310 will move downward to adapt to the height. Therefore, the carton 104 can still be supported and fixed on both sides when the height changes.

[0034] like Figure 1-4 As shown, both ends of the slide bar 305 are fixedly equipped with blocking blocks 307. The blocking blocks 307 can restrict the movement of the sliding sleeve 304, prevent the sliding sleeve 304 from detaching from the slide bar 305 due to excessive movement, and at the same time can effectively reduce the excessive stretching of the spring 306, thereby causing the spring 306 to fatigue faster.

[0035] like Figure 1-4 As shown, a cardboard box 104 is placed on the upper side of the outer surface of the platform 101, a vertical plate 102 is fixedly installed on one side of the outer surface of the platform 101, and a top plate 103 is fixedly installed on the upper part of the outer surface of the vertical plate 102. The vertical plate 102 is used to support the entire fixed structure, and the top plate 103 is used to fix the telescopic rod 301.

[0036] like Figure 1-4 As shown, rectangular blocks 201 are fixedly installed on both sides of the outer surface of the platform 101. Trapezoidal grooves 202 are opened on the upper side of the outer surface of the two rectangular blocks 201. The sliders 203 are movably fitted inside the two sliders 203. The two sides slide in the trapezoidal grooves 202 through the sliders 203, so that the slot opening device can move freely, thereby enabling slot opening on multiple sides of the carton 104.

[0037] like Figure 1-4 As shown, telescopic rods 204 are fixedly connected to the upper surface of the outer surfaces of the two sliders 203. A grooving machine 205 is fixedly installed on the upper surface of the outer surfaces of the two telescopic rods 204. The height of the grooving machine 205 can be adjusted by the telescopic rods 204, so that slots can be opened at different positions according to specific conditions.

[0038] like Figure 1-4As shown, two sliding sleeves 304 are movably connected to the lower side of their outer surfaces. The other ends of the two sliding sleeves 304 are rotatably connected to the upper side of the outer surface of the same pressure plate 313. When the telescopic rod 301 moves downward, the pressure plate 313 will apply pressure to the bottom of the carton 104, thereby fixing the position of the carton 104 so that it will not move, thus facilitating the opening of the carton.

[0039] Working principle: In use, the telescopic rod 301 located under the top plate 103 is activated, causing it to extend downwards. This moves the entire fixed support structure downwards. When the pressure plate 313 at the bottom touches the bottom of the carton 104, the telescopic rod 301 continues to extend. Since the pressure plate 313 stops moving after touching the bottom, the connecting rods 303 on both sides of the sliding sleeve 304 rotate to both sides under the action of the telescopic rod 301. The connecting rods 303 control the sliding sleeve 304 to slide along the sliding rod 305 to both sides. The sliding sleeve 304 pushes the support plate 310 connected by the connecting strip 308 and the cross plate 309 to move to both sides of the carton 104 until the support plate 310 touches the side of the carton 104. At this point, the telescopic rod 301 stops extending. At the same time, the sliding rod 311 compresses the spring 31. 4. Slide upwards to adapt to the structural height. At the same time, the L-shaped plate 312 on the lower side of the slide bar 311 can assist the support plate 310 and the pressure plate 313 in supporting and fixing the carton 104. At this time, adjust the height of the telescopic rod 204 on both sides of the slider 203 to adjust the punching position. Then, push the slider 203 on both sides of the rectangular block 201 to slide towards the carton 104. When the slotting machine 205 on the upper side of the telescopic rod 204 is released to the carton 104, the slot can be opened. After the punching is completed, the telescopic rod 301 can be retracted. When the telescopic rod 301 no longer provides downward pressure, the spring 306 will pull the sliding sleeve 304 on both sides to retract, so that the support plate 310 on both sides can stop supporting the sides of the carton 104, thereby contacting the fixation of the carton 104, which facilitates the subsequent removal of the carton 104.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
