Description

Technical Field

[0001] The utility model relates to box folding equipment, in particular to a feeding mechanism of a box folding machine. Background Art

[0002] At present, in the manufacturing process, most of the simple packaging boxes are folded manually, resulting in high labor costs and low work efficiency. In addition, folding packaging boxes is a mechanical and repetitive labor, the labor intensity of workers is high, and the quality of packaging boxes is uneven. In the prior art, an automatic box folding machine is used to replace manual box folding, which effectively solves the problems of high labor costs and high labor intensity. The automatic box folding machine mainly includes a cardboard storage mechanism, a cardboard transfer mechanism, a folding mechanism, a shaping mechanism and a finished product output mechanism. The cardboard blanks stacked in the storage mechanism are picked up one by one and then transferred to the top of the folding mechanism by the transfer mechanism. The folding mechanism and the shaping mechanism cooperate with each other to form the blanks, and finally the finished product output mechanism transmits them outward. The whole process forms an overall assembly line action.

[0003] Loading and folding are crucial in the entire folding process, which determines the efficiency of the process. However, cardboard blanks are generally made by uniformly cutting and cutting large pieces of stacked cardboard according to specifications. During the production process, factors such as burrs will cause adhesion between cardboard blanks, especially for oily cardboard with large surface electrostatic adsorption. Oily cardboard is easy to stick after stacking, and it is difficult to ensure that it can be transported one by one using a suction cup transfer mechanism. It also needs to be separated manually, which leads to stagnation of processing efficiency and difficulty in improving efficiency. Moreover, although the cardboard blanks are separated manually, they still need to be stacked and placed in the storage mechanism for loading. Stacking again may still cause adhesion for oily cardboard, and it is impossible to ensure that the cardboard blanks are loaded one by one, which will cause jamming and blockage problems, causing mechanical failure.

[0004] Therefore, on the basis of ensuring that the feeding action is completed smoothly, designing a folding box machine storage mechanism that can improve the feeding efficiency and ensure that the materials are fed one by one is the research purpose of the utility model. Utility Model Content

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a feeding mechanism for a box folding machine, and the material storage mechanism for the box folding machine can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A feeding mechanism for a box folding machine, comprising:

[0008] The material storage mechanism comprises a support frame which can be moved left and right, and a storage area for stacking cardboard blanks is surrounded by a plurality of vertically fixed limiting rods on the support frame, and at least one limiting rod is arranged on the same side of the storage area;

[0009] A material control mechanism is used to position the second layer of paperboard blanks. The limiting rod slides up and down facing a side wall of the storage area and is turned over to be provided with a corresponding S-shaped elastic member. The upper end portion of the S-shaped elastic member is pressed against the top of the uppermost paperboard blank. The lower folded portion of the S-shaped elastic member is abutted against or spaced against the side wall of the second layer of paperboard blanks. The length of the upper bending portion of the S-shaped elastic member is greater than that of the lower bending portion, and the upper bending end extends forward and is placed on the front side of the S-shaped elastic member.

[0010] The material taking mechanism is used for sucking up the cardboard blanks one by one, and comprises at least one group of vacuum suction cups which are synchronously moved up and down and are arranged above the material storage mechanism.

[0011] The side wall of the limit rod facing the storage area is recessed inward and has an embedding groove extending upward to the top thereof. The material control mechanism includes a special-shaped part that can be slidably installed in the embedding groove up and down. The special-shaped part includes a cross bar in the middle and V-shaped rods that are integrally and symmetrically fixed to the two end portions of the cross bar. The S-shaped elastic part is rotatably installed in the middle of the cross bar.

[0012] The two ends of the V-shaped rod are fixedly connected with vertically arranged guide rollers, and the embedding groove is located at the position for installing the guide roller and is arranged as an arc-shaped surface adapted to the guide roller; the middle part of the S-shaped elastic member is fixedly connected with a sleeve that passes through the cross bar, and the cross bar is detachably fixed with limiting rings for limiting the sleeve on both side edges of the sleeve.

[0013] The material storage mechanism also includes a driving cylinder for driving the support frame to move left and right, and a group of limit guide rails arranged side by side in front and back with intervals. The driving cylinder is arranged side by side between two of the limit guide rails. A number of sliders compatible with the limit guide rails are fixedly connected at equal intervals on the left and right sides of the lower part of the support frame corresponding to the position of the limit guide rails. The support frame is movably installed on the limit guide rails through a sliding connection of the sliders.

[0014] A plurality of storage areas are arranged side by side on the support frame through a plurality of limit rods, and two of the limit rods are installed side by side at intervals on the same side of the storage area; two limit rods are arranged side by side at intervals between two adjacent storage areas, and the limit rod arranged between the two storage areas is provided with corresponding embedding grooves on both side edges facing the storage areas, and S-shaped elastic parts are installed in the embedding grooves through corresponding special-shaped parts.

[0015] The vacuum suction cup is installed on the base frame through a suction cup frame with an adjustable vacuum suction cup installation height, and the suction nozzles of the vacuum suction cup are located on the same horizontal plane. The vacuum suction cup is externally connected to the same vacuum pump through a corresponding air supply pipe.

[0016] A motor for driving the vacuum suction cup to move up and down synchronously is connected to the middle of the base frame. The motor drives the base frame to move up and down through a screw transmission.

[0017] The suction cup frame includes an L-shaped connecting plate fixedly connected to a base frame, and a connecting rod with a terminal end connected to a vacuum suction cup is provided through the L-shaped connecting plate and is pulled up and down, and scales are distributed on the outer side wall of the connecting rod.

[0018] Advantages of the utility model:

[0019] 1) The utility model sets a material storage mechanism and a material control mechanism to cooperate in limiting and fixing the stacked cardboard blanks. At the same time, the material storage mechanism is used to install the material control mechanism, thereby having a limiting and fixing effect on the second layer of cardboard blanks. The cardboard blanks are fed one by one in cooperation with the material taking mechanism to ensure rapid feeding, and effectively prevent the problem of slow feeding speed caused by the sticking of the stacked cardboard blanks.

[0020] 2) The utility model uses a special-shaped piece that slides up and down to rotatably install an S-shaped elastic piece on the side of the limiting rod on all sides. The upper end of the S-shaped elastic piece is pressed against the top of the top cardboard blank, and the lower bend of the S-shaped elastic piece abuts or is spaced against the side wall of the second cardboard blank. When the suction cup of the material-taking mechanism sucks the top cardboard blank upward, the S-shaped elastic piece rotates outward to make way, and its lower bend rotates toward the side wall of the second cardboard blank due to the outward movement of the upper bend, and abuts and presses against the side wall of the second cardboard blank. Multiple positioning points on the four sides cooperate to fully fix the second cardboard blank at the same time, thereby effectively preventing the second cardboard blank from moving up with the upper cardboard blank due to sticking problems, so as to ensure that the materials are loaded and transported one by one.

[0021] 3) However, such a setting can only ensure the transfer of the first layer of materials, and cannot achieve the loading of each layer of materials one by one. Therefore, the utility model sets the S-shaped elastic member to have elastic properties, the length of its upper side bending part is greater than the length of the lower side bending part, and the upper side bending end extends forward and is placed on the front side of the S-shaped elastic member to ensure that the center of gravity of the S-shaped elastic member is still biased towards one side of the cardboard blank during rotation, so that after the upper cardboard blank is removed, the S-shaped elastic member moves downward with the special-shaped member, and the S-shaped elastic member is reset and rotated to the upper side bending part to be re-pressed against the second layer of cardboard blank, and such repeated actions effectively ensure that each layer of cardboard blank is loaded one by one; and the setting of the embedding groove can effectively control the outward rotation angle of the S-shaped elastic member to prevent it from over-turning, further promoting its reset.

DETAILED DESCRIPTION

[0030] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0031] refer to Figure 1-7 , a feeding mechanism for a box folding machine, comprising:

[0032] The storage mechanism 1 comprises a support frame 101 which can be moved left and right, and a storage area for stacking cardboard blanks is surrounded by a plurality of vertically fixed limiting rods 102 on the support frame 101, and at least one limiting rod 102 is arranged on the same side of the storage area;

[0033] The material control mechanism 2 is used to position the second layer of paperboard blanks. The limiting rod 102 slides up and down and is turned over to be provided with a corresponding S-shaped elastic member 202 facing a side wall of the storage area. The upper end of the S-shaped elastic member 202 is pressed against the top of the uppermost paperboard blank. The lower folded part of the S-shaped elastic member 202 is abutted against or spaced against the side wall of the second layer of paperboard blanks. The length of the upper bending part of the S-shaped elastic member 202 is greater than that of the lower bending part, and the upper bending end extends forward and is placed on the front side of the S-shaped elastic member 202.

[0034] The material taking mechanism 3 is used for sucking up the cardboard blanks one by one, and comprises at least one group of vacuum suction cups 301 which are arranged above the material storage mechanism 1 and move up and down synchronously.

[0035] The utility model sets a material storage mechanism 1 and a material control mechanism 2 to cooperate in limiting and fixing the stacked cardboard blanks. At the same time, the material storage mechanism 1 is used to install the material control mechanism 2, thereby having a limiting and fixing effect on the second layer of cardboard blanks. The cardboard blanks are fed one by one in cooperation with the material taking mechanism 3 to ensure fast feeding, and effectively prevent the problem of slow feeding speed caused by the sticking of the stacked cardboard blanks.

[0036] The side wall of the limiting rod 102 facing the storage area is recessed inward and is provided with an embedding groove 1021 extending upward to the top thereof. The material control mechanism 2 includes a special-shaped part 201 that can be slidably installed in the embedding groove 1021 up and down. The special-shaped part 201 includes a cross bar 2011 in the middle, and V-shaped rods 2012 that are integrally and symmetrically fixed to the two end portions of the cross bar 2011. The S-shaped elastic part 202 is rotatably installed in the middle of the cross bar 2011.

[0037] The two ends of the V-shaped rod 2012 are fixedly connected with vertically arranged guide rollers 2013, and the embedding groove 1021 is located at the position for installing the guide roller 2013 and is arranged as an arc-shaped surface adapted to the guide roller 2013; the middle part of the S-shaped elastic member 202 is fixedly connected with a sleeve 2021 that passes through the cross bar 2011, and the cross bar 2011 is detachably fixed with limiting rings 203 on both sides of the sleeve 2021 for limiting the sleeve 2021.

[0038] The arrangement of the V-shaped rod 2012 can effectively ensure the installation guide roller 2013 of the special-shaped part 201 and the arrangement of the arc surface of the embedding groove 1021, so that the special-shaped part 201 can smoothly and stably slide up and down in the embedding groove 1021, thereby ensuring the stable installation of the S-shaped elastic part 202.

[0039] The utility model rotates and installs the S-shaped elastic member 202 on the side of the limiting rod 102 around the periphery through the special-shaped member 201 that is set to slide up and down, and the upper end of the S-shaped elastic member 202 is pressed against the top of the top cardboard blank, and the lower side bending part of the S-shaped elastic member 202 abuts or is spaced against the side wall of the second cardboard blank. When the suction cup of the material taking mechanism 3 sucks the top cardboard blank upward, the S-shaped elastic member 202 rotates outward to make way, and its lower side bending part rotates toward the side wall of the second cardboard blank due to the outward movement of the upper side bending part and abuts and presses against the side wall of the second cardboard blank. Multiple positioning points on four sides cooperate to fully fix the second cardboard blank at the same time, thereby effectively preventing the second cardboard blank from moving up with the upper cardboard blank due to the sticking problem, so as to ensure that the materials are loaded and transported one by one.

[0040] However, such a setting can only ensure the transfer of the first layer of materials, and cannot achieve the loading of each layer of materials one by one. Therefore, the utility model sets the S-shaped elastic member 202 to have elastic properties, the length of its upper side bending portion is greater than the length of the lower side bending portion, and the upper side bending end extends forward and is placed on the front side of the S-shaped elastic member 202 to ensure that the center of gravity of the S-shaped elastic member 202 is still biased to one side of the cardboard blank during rotation, so that after the upper cardboard blank is removed, the S-shaped elastic member 202 moves downward with the special-shaped member 201, and the S-shaped elastic member 202 is reset and rotated to the upper side bending portion to be re-pressed against the second layer of cardboard blank, and such repeated actions effectively ensure that each layer of cardboard blank is loaded one by one; and the setting of the embedding groove 1021 can effectively control the outward rotation angle of the S-shaped elastic member 202 to prevent it from over-turning, further promoting its reset.

[0041] The material storage mechanism 1 also includes a driving cylinder 103 for driving the support frame 101 to move left and right, and a group of limit guide rails 104 arranged side by side in front and back. The driving cylinder 103 is arranged side by side between two limit guide rails 104. A plurality of sliders compatible with the limit guide rails 104 are fixedly connected at equal intervals on the left and right sides of the lower part of the support frame 101 corresponding to the position of the limit guide rails 104. The support frame 101 is movably installed on the limit guide rails 104 through the sliding connection of the sliders.

[0042] A plurality of storage areas are arranged side by side on the support frame 101 through a plurality of limit rods 102, and two limit rods 102 are installed side by side at intervals on the same side of the storage area; two limit rods 102 are arranged side by side at intervals between two adjacent storage areas, and the limit rod 102 arranged between the two storage areas is provided with corresponding embedding grooves 1021 on both sides facing the storage areas, and S-shaped elastic parts 202 are installed in the embedding grooves 1021 through corresponding special-shaped parts 201.

[0043] The storage quantity of cardboard blanks is increased by arranging a plurality of storage areas side by side, and the supporting frame 101 is driven to move left and right to adapt to the material taking mechanism 3 by driving the air cylinder 103, thereby improving the practical effect.

[0044] The vacuum suction cup 301 is installed on the base frame 4 through a suction cup frame with an adjustable installation height of the vacuum suction cup 301, and the suction nozzles of the vacuum suction cup 301 are located on the same horizontal plane. The vacuum suction cup 301 is externally connected to the same vacuum pump through a corresponding air pipe.

[0045] A motor 5 for driving the vacuum suction cup 301 to move up and down synchronously is connected to the middle of the base frame 4. The motor 5 drives the base frame 4 to move up and down through a screw transmission.

[0046] The suction cup frame 302 includes an L-shaped connecting plate fixedly connected to the base frame, and a connecting rod with a terminal end connected to the vacuum suction cup 301 is provided through the L-shaped connecting plate and pulled up and down, and the outer side wall of the connecting rod is distributed with scales.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
