Description

Technical Field

[0001] The present invention relates to the technical field of cardboard conveying equipment, and specifically relates to a cardboard conveying and feeding device for carton production. Background Art

[0002] In the carton processing industry, the cardboard feeding mechanism is one of the key equipment for realizing automated production. Its main function is to convey the cardboard to the processing equipment according to the preset path and speed to ensure the continuity and high efficiency of the processing process. The design and performance of the feeding mechanism directly affect the quality, efficiency, and safety of carton processing.

[0003] In the early days, carton processing mainly relied on manual feeding. Workers manually pushed the cardboard into the processing equipment. This method was not only inefficient but also had a high safety risk. With the advancement of industrial automation, mechanical feeding mechanisms gradually replaced manual feeding. Common mechanical feeding mechanisms include roller feeding, chain feeding, and belt feeding, etc. However, there are still some problems with these existing feeding mechanisms, which are as follows:

[0004] The existing cardboard feeding mechanism cannot fix and clamp the cardboard well. Some clamping structures may cause damage to the cardboard during the clamping process due to the inability to accurately control the clamping force, which directly leads to the cardboard being unable to be used normally. At the same time, it cannot adjust the width in a timely manner according to different sizes of cardboard to adapt, resulting in low efficiency and poor use effect of the entire feeding mechanism. For this reason, we propose a cardboard conveying and feeding device for carton production. Summary of the Invention

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the cardboard conveying and feeding device for carton production involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0037] See also Figures 1-6, A cardboard conveying and feeding device for carton production, comprising a base 1. At the top ends on both sides of the base 1, slide rails 2 are fixedly arranged. On the back of the inner side surface at one end of the base 1, an electromagnetic adsorption component 3 is fixedly installed, and an electric telescopic clamping rod 4 is fixedly installed at the other end. At the other end inside the base 1, a discharging pushing component 5 is fixedly installed. On the front of the inner side surface at one end of the base 1, a driving motor 6 is fixedly installed. On the output shaft of the driving motor 6, a driving gear 7 is fixedly installed. A bracket 8 is movably arranged on the slide rails 2. At the bottom end of the bracket 8, a linear guide rail 9 is fixedly installed. On the bracket 8, a driving screw rod 10 is movably installed. At one end of the driving screw rod 10, a driven gear 11 is fixedly installed. On the driving screw rod 10, a clamping component 12 is movably installed. On the side surface of the bracket 8, an inner locking component 13 is fixedly installed;

[0038] Compared with the prior art, in this application, by providing a bracket 8 with a clamping component 12 installed, the brackets 8 are placed on the base 1 one by one. Then, when the cardboard rolls into the clamping component 12 from the side, the driving motor 6 on the side can be used to drive the driving gear 7 to rotate, thereby driving the driving screw rod 10 to rotate. In this way, the clamping components 12 on both sides can be driven to move towards the middle to clamp both ends of the cardboard, thereby achieving an effective clamping effect on cardboard of different sizes. And the stability of the cardboard during the feeding process can be ensured by the clamping of the clamping component 12, avoiding the situation that the cardboard transportation deviates and subsequent ineffective processing cannot occur. At the same time, by providing an electromagnetic adsorption component 3 and an inner locking component 13, the electromagnetic adsorption component 3 is started at the feeding end to generate magnetic attraction to attract the inner locking component 13, so that the whole bracket 8 can be fixed at this position, thereby ensuring that the rotation of the driving gear 7 can act on the driven gear 11, and then realizing the adjustment of the distance between the clamping components 12. At the discharging end, a discharging pushing component 5 is provided. By using the cooperation of the discharging pushing component 5 and the internal structure of the clamping component 12, the cardboard can be quickly lifted at this end by the discharging pushing component 5 to achieve effective discharging, ensuring the use effect of this feeding mechanism. At the same time, the clamping component 12 also has a clamping self-locking function. After the clamping force on the cardboard reaches a certain degree, the positions of the clamping components 12 on both sides can be automatically locked, so as to ensure the clamping effect without damaging the cardboard, and at the same time, the clamping effect on the cardboard can be locked to ensure the stability during the transportation process.

[0039] Please refer to Figures 1-6 , A cardboard conveying and feeding device for carton production, comprising a base 1 and a bracket 8. The base 1 and the bracket 8 are U-shaped, and extension short boards are arranged on both sides at the top of the bracket 8. The number of driving motors 6 is two, and the electromagnetic adsorption component 3 and one driving motor 6 are coaxially arranged at the same end inside the base 1. The linear guide rail 9 is fixedly arranged on the upper surface at the bottom end of the bracket 8. Inside the lower part of both ends at the top of the bracket 8, rollers are embedded and movably installed. Opposite threads are arranged at both ends of the driving screw rod 10;

[0040] In this embodiment, it should be noted that by using the extended short plates on both sides of the bracket 8 to rest on the slide rail 2, it can move thereon, ensuring that it can drive the cardboard to move and convey on the base 1. And the electromagnetic suction accessory 3 can lock the overall position of the bracket 8 to ensure that the subsequent drive motor 6 can drive the bracket 8 to drive the driven gear 11 to rotate, and then drive the drive screw 10 to adjust the distance between the clamping components 12 on both sides, so as to ensure the stability of the clamping effect on the cardboard.

[0041] Please refer to Figures 2-3 , a cardboard conveying and feeding device for carton production, including a discharging pushing component 5. The discharging pushing component 5 includes an electric push rod 51. The top end of the electric push rod 51 is fixedly installed with an air guide pipe 52, and the top end of the air guide pipe 52 is fixedly installed with an air outlet 53;

[0042] In this embodiment, it should be noted that one end of the air guide pipe 52 is connected to an external air supply device through a hose, and the air outlet 53 can be inserted into the bottom end of the clamping component 12 for sealed docking. In this way, when it is necessary to unload the cardboard, the external air supply device can supply air to the air guide pipe 52, so that the air outlet 53 inserted into the bottom end of the clamping component 12 supplies air, causing the clamping component 12 to lift the cardboard carried thereon and roll it to one side, thereby realizing the unloading of the cardboard.

[0043] Please refer to Figures 1-11 , a cardboard conveying and feeding device for carton production, including a clamping component 12. The clamping component 12 includes a clamping block 121. The clamping block 121 is composed of two parts. The upper part is an L-shaped structure, and the lower part is a vertical plate structure.

[0044] In this embodiment, it should be noted that the supporting structure 123 is arranged in a two-part symmetrical structure, and the limiting round rod 126 is arranged at one end of the supporting structure 123. The locking structure 125 is inserted through the buffer gasket 124. The bottom end of the locking structure 125 passes through the clamping block 121. The track groove 127 is slidably arranged by being clamped on the linear guide rail 9, and rollers are embedded and movably installed inside the track groove 127. The inner air duct 128 is hermetically connected to the bottom structure of the supporting structure 123. In this way, the linear guide rail 9 can be clamped in the track groove 127 to limit the overall linear sliding of the clamping assembly 12 on the bracket 8, so as to ensure that the clamping distances of the clamping assemblies 12 at both ends can be well adjusted according to the length of the cardboard to ensure the clamping stability. Moreover, by the structural arrangement of the locking structure 125, it is also possible to automatically lock the position of the clamping assembly 12 on the driving screw 10 after the clamping is stable, and it will not cause damage to the end of the cardboard, ensuring the integrity of the cardboard.

[0045] Please refer to Figures 8-12 , a cardboard conveying and feeding device for carton production, including a supporting structure 123. The supporting structure 123 includes a vertical support plate 1231 and a base 1232. A supporting plate 1233 is movably installed at the top of the vertical support plate 1231. An air outlet end 1234 is fixedly installed on one side of the vertical support plate 1231. An air delivery pipe 1235 is fixedly installed at the bottom end of the air outlet end 1234. An air outlet pipe 1236 is fixedly installed at the top end of the air outlet end 1234. The inside of the base 1232 is hollow and a telescopic sleeve rod 1237 is fixedly installed. The top end of the telescopic sleeve rod 1237 is movably installed with a support roller 1238 through an extension frame. A first spring 1239 is sleeved outside the telescopic sleeve rod 1237;

[0046] In the present embodiment, it should be noted that the supporting plate 1233 is rotatably connected to the vertical supporting plate 1231. The supporting plate 1233 is a bent structure and opens downward. The angle of the opening is an obtuse angle. In the natural state, the weight of the straight line segments of the supporting plate 1233 adjacent to the edges of the inner walls of the groove 122 is greater than the weight of the other segment, and a bendable splicing plate is provided at the end of the heavier segment, which can be locked on the clamping block 121 by a limiting bolt. The splicing plates of the supporting plates 1233 on both sides retain one side that is locked with the clamping block 121 by a limiting bolt, and the limiting round rod 126 is spaced apart at the bottom end of the heavier segment. The bottom end of the air supply pipe 1235 is sealed and connected with the inner air duct 128. The support trigger structure 129 is in contact with the supporting plate 1233, and 1288 is The part connected by the telescopic sleeve 1237 is provided with an expansion convex ring, and the first spring 1239 is arranged between the expansion convex ring and the inside of the base 1232, and the support roller 1238 is arranged at a distance from the lower surface of the supporting plate 1233, so that when the cardboard rolls to the surface of the supporting plate 1233, it can be supported by the support trigger structure 129 on one side to ensure that the cardboard can stably roll to the adjacent ends of the two supporting plates 1233 and get stuck, and when the cardboard needs to be pushed out from the middle for unloading later, the high-pressure gas sprayed from the bottom air outlet pipe 1236 is used to push the supporting plate 1233 to rotate around the top of the vertical supporting plate 1231, so that the cardboard is lifted from the middle by the supporting plate 1233 on one side and rolls to the other side, and then rolls out through the supporting plate 1233 on the other side to complete the unloading.

[0047] See also Figures 10-13 A cardboard conveying and feeding device for carton production includes a locking structure 125, the locking structure 125 includes a straight plate 1251, a trigger rod 1252 is fixedly installed on one side of the straight plate 1251, a resisting rod 1253 is contacted and connected at the bottom end of the straight plate 1251, second springs 1254 are fixedly installed on both sides of the resisting rod 1253 through supporting plates, and a locking ring 1255 is fixedly installed at the bottom end of the resisting rod 1253;

[0048] In this embodiment, it should be noted that convex edges are respectively provided on both sides of the straight plate 1251 and balls are provided at the bottom. The trigger rod 1252 is evenly distributed and fixedly installed. A buffer pad is installed at the end of the trigger rod 1252. The top of the contact rod 1253 is a pointed inclined surface structure and the inclined surface is arranged to fit the bottom end of the straight plate 1251. The bottom end of the second spring 1254 is located inside the clamping block 121 and is fixedly installed. The inner diameter of the locking ring 1255 is the same as the outer diameter of the driving screw 10, and an elastic pad is provided on the inner ring. When the trigger rod 1252 moves, it can contact the end of the cardboard when the clamping block 121 moves. When the clamping force continues to increase, it will press the straight plate 1251 to squeeze the resistance rod 1253, so that the resistance rod 1253 will drive the locking ring 1255 to move downward until it is stably squeezed with the surface thread of the driving screw 10 to complete the locking, thereby achieving automatic locking after the cardboard is clamped to a certain extent, avoiding damage to the cardboard due to excessive clamping force, and this clamping degree can be achieved by designing the length of the trigger rod 1252 to achieve the adjustment of the clamping force.

[0049] See also Figures 10-11 A cardboard conveying and feeding device for carton production includes a support trigger structure 129, the support trigger structure 129 includes a straight rod 1291, a transverse insert plate 1292 is provided at the top of the straight rod 1291, and a third spring 1293 is fixedly installed at one end of the transverse insert plate 1292;

[0050] In this embodiment, it should be noted that the bottom end of the straight rod 1291 can be arranged in contact with the inner locking component 13, the top end of the straight rod 1291 is a pointed inclined surface structure and the inclined surface is arranged toward the side where the transverse insertion plate 1292 is located, and the end of the transverse insertion plate 1292 located outside the clamping block 121 can support the bottom of the supporting plate 1233, and one end of the third spring 1293 is fixedly connected to the inside of the clamping block 121, and the third spring 1293 is in a stretched state when the straight rod 1291 is raised and lifted. In this way, the inner locking component 13 can be used to lift up the end of the straight rod 1291 located at the loading process, so that the transverse insertion plate 1292 at this end is supported on the lower surface of the supporting plate 1233 to ensure that the loading end can feed stably.

[0051] See also Figures 6-7 A cardboard conveying and feeding device for carton production includes an inner locking assembly 13, the inner locking assembly 13 includes a shell 131, a return spring is arranged inside the shell 131, a sliding block 132 is movably installed inside the shell 131, a long rod 133 is fixedly installed at the bottom end of the sliding block 132, and a push block 134 is fixedly installed on the upper surface of the long rod 133;

[0052] In this embodiment, it should be noted that a circular plate is connected to the slider 132 on one side inside the housing 131 through a round rod, and the circular plate abuts against one end of the internal return spring, while the other end of the return spring abuts against the inside of the housing 131. A circular hole is provided in the middle of the outer end of the slider 132, and a positioning round rod is provided at the end of the electric telescopic clamping rod 4. The circular hole is fitted with the positioning round rod. The push block 134 at the end of the electric telescopic clamping rod 4 abuts against the bottom end of the straight rod 1291. In this way, during the discharging process, the straight rod 1291 is pushed up by the push block 134, so that the third spring 1293 releases the support for the bottom of the supporting plate 1233. In this way, the rotation amplitude of the supporting plate 1233 can be larger, so as to ensure that it can more reliably push the cardboard to the other supporting plate 1233 for discharging.

[0053] Working principle: Place the brackets 8 on the slide rails 2 one by one, connect the power supply of the electromagnetic adsorbing component 3 to generate magnetic suction force, so that the push block 134 moves horizontally and inserts into the electromagnetic adsorbing component 3 to lock the position of the bracket 8. At the same time, the straight rod 1291 is pushed up, so that the horizontal insertion plate 1292 is pushed out to support the lower surface of the supporting plate 1233 at the feeding end to form a support. Then, the cardboard is pushed from one side of the clamping block 121 to the supporting plate 1233. After the cardboard rolls between the two supporting plates 1233, it drops and automatically centers. Then, start the driving motor 6 to drive the driving gear 7 to rotate, and then the driven gear 11 rotates. In this way, the driving screw 10 can be driven to rotate to drive the clamping components 12 on both sides to move towards the middle. When slowly clamping the cardboard, the trigger rod 1252 will be continuously squeezed, and then the straight plate 1251 will squeeze the abutting rod 1253 to move downward. In this way, the locking ring 1255 will move towards the surface of the extended driving screw 10 and fit. Until the frictional force of the fit is greater than the rotational torque force of the driving screw 10, then the power supply of the electromagnetic adsorbing component 3 is disconnected, and the bracket 8 that has completed the fixing of the cardboard is removed to fix and clamp the next cardboard. During discharging, use the driving motor 6 at the discharging end to drive the driving gear 7 to rotate, and finally unlock the clamping of the clamping component 12. Supply air to the air outlet 53 by using an external air supply device, and start the electric push rod 51 to extend so that the air outlet 53 is inserted into the internal air duct 128.
