Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, and particularly relates to a feeding mechanism applied to a case packing machine. Background Art

[0002] In the prior art, the feeding mechanism of a case packing machine includes a feeding station, a stacking station and a pushing station. Materials are conveyed to the stacking station through the feeding station, further stacked through the stacking station, and then the materials at the stacking station are pushed to a designated position by the pushing station, so as to facilitate the subsequent case packing operation. However, the materials at the stacking station are prone to offset or fall during stacking. Summary of the Invention

[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a feeding mechanism applied to a case packing machine, and a pressing plate is arranged at the stacking station, so that the materials can be pressed during stacking, thereby preventing them from offsetting or falling and making the feeding more stable.

[0004] The utility model discloses a feeding mechanism applied to a case packing machine, which includes a feeding station, a stacking station and a pushing station. A conveyor belt and a conveyor motor for driving the conveyor belt to work are arranged at the feeding station. The pushing station includes a placing table, a feeding pusher for pushing the materials at the stacking station to the placing table, and a pusher driving member for driving the displacement of the feeding pusher. It is characterized in that: a stacking rack and a lifting table arranged below the stacking rack are arranged at the stacking station. The lifting table is connected with the output end of the conveyor belt to form a material receiving structure. A stacking bin is arranged on the stacking rack. A turning support frame is hinged at the bottom of the stacking bin on the stacking rack. When the lifting table drives the materials to rise, the turning support frame can rotate outwards and open. A reset member for driving it to reset after the turning support frame rotates and opens is also included. When the top of the turning support frame rotates to a horizontal state, a limiting member for limiting the reset angle of the turning support frame is also arranged on the stacking rack. And a pressing block for flattening the materials is arranged on the side wall of the stacking bin on the stacking rack. The pressing block is guided and slides vertically on the stacking rack.

[0005] The above-mentioned technical scheme is adopted, when in use, the conveyor belt can transport the materials to the top of the lifting platform. At this time, the lifting platform rises, and the flip support frame rotates outward to open, so as to make a passage, so that the materials on the lifting platform enter the stacking bin. At this time, the reset part drives the flip support frame to rotate and reset, so that the flip support frame supports the bottom of the materials to prevent them from falling. The limit part keeps the flip support frame in a supporting state. Furthermore, when the second group of materials enters the stacking bin, the second group of materials will be supported at the bottom of the first group of materials, and the flip support frame will be supported at the bottom of the second group of materials. Reciprocating operation can achieve stacking, and when stacking, the pressing block will be pressed on the top of the uppermost material to prevent the materials from shifting or tipping over. Furthermore, the materials can be pushed to the storage table by driving the loading push handle to slide through the push handle driving part.

[0006] The utility model is further configured as follows: the stacking rack is provided with a guide rod arranged in the vertical direction and a slider sliding on the guide rod, the pressure block is arranged on the slider and extends into the stacking bin, and the bottom of the slider is also provided with an elastic buffering member which elastically contacts the stacking rack when the slider slides down.

[0007] By adopting the above technical solution, the slider can facilitate the installation of the pressing block. When in use, the slider can slide down relatively due to gravity to press the pressing block on the material. When the material is taken away, the slider will automatically slide down due to gravity. The elastic buffer can prevent the slider from making hard contact with the stacking frame when sliding down, thereby playing a protective role.

[0008] The utility model is further configured as follows: the conveyor belts are arranged in two groups relatively to each other, and both groups of conveyor belts include a flat conveyor belt I and a conveyor belt II erected on one side of the conveyor belt I.

[0009] By adopting the above technical solution, the flat conveyor belt I can play the role of support and main transportation, the conveyor belt II can assist the conveyor belt I in transportation, and the conveyor belt II moves together with the conveyor belt I, which can further prevent material deflection.

[0010] The utility model is further configured as follows: two conveying motors are also provided, each conveying motor corresponds to a group of conveyor belts, a bevel gear is sleeved on the output shaft of the conveying motor, the end of the output shaft is linked with the conveyor belt II, and the bevel gear is linked with the conveyor belt I.

[0011] By adopting the above technical solution, each set of conveyor belts I and II are driven by the same conveying motor, which can prevent speed difference from occurring during startup and make the conveyor belts more stable during operation.

[0012] Further setting of the present utility model: There are two sets of oppositely arranged mounting plates on the feeding station. An adjusting screw rod for adjusting the distance between the two is provided on the mounting plates. Two conveyor belts are respectively arranged on the corresponding mounting plates, and two conveyor motors are also arranged on the corresponding mounting plates.

[0013] With the above technical solution, the distance between the two conveyor belts can be adjusted by adjusting the mounting plates, and there is no need to separately adjust the conveyor belts, making it more convenient during adjustment.

[0014] Further setting of the present utility model: The placement table is guided to slide on the pushing station. A guiding opening is provided on the placement table, and the guiding opening is arranged in a constricted shape, with its large opening end facing the material.

[0015] With the above technical solution, the guiding sliding of the placement table enables its front and rear positions to be relatively adjusted, with stronger practicability. The guiding opening can play a guiding role during the pushing of the material, and can further prevent the material from skewing.

[0016] Further setting of the present utility model: A abutting surface is further provided on the placement table. And the feeding pusher includes a mounting frame, a left arm and a right arm. The left arm is guided to slide vertically on the mounting frame, and a left arm driving member for driving the relative telescopic movement of the left arm is further included. The right arm is located above the abutting surface.

[0017] With the above technical solution, the pusher driving member can drive the overall sliding of the mounting frame, so that the left arm can abut the material against the abutting surface, thus achieving a correcting effect. Further, the right arm being higher than the abutting surface can avoid being touched during movement, and the left arm can be relatively telescopic, which can be applicable to pushing materials of different heights.

[0026] The following further describes the specific embodiments of the present utility model in detail with reference to the accompanying drawings:

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] The utility model discloses a feeding mechanism used in a cartoning machine, including a feeding station 1, a stacking station 2 and a pushing station 3. The feeding station 1 is provided with a conveyor belt 11 and a conveying motor 12 that drives the conveyor belt 11 to work. The pushing station 3 includes a storage platform 31, a loading pusher 32 that pushes the materials on the stacking station 2 to the storage platform 31, and a pusher driving member 33 that drives the loading pusher 32 to move (the pusher driving member 33 is most preferably an electric cylinder, and of course it can be an air cylinder or a motor. The specific installation method belongs to the common knowledge of technicians in this field, and will not be described in detail in this article). In the implementation case of the utility model, the stacking station 2 is provided with a stacking rack 21 and a lifting platform 22 arranged below the stacking rack 21 (the lifting and lowering of the lifting platform 22 can be driven by a motor, an electric cylinder or an air cylinder, and the specific movement method belongs to the common knowledge of technicians in this field), the lifting platform 22 is connected with the output end of the conveyor belt 11 to form a material receiving structure, the stacking rack 21 is provided with a stacking bin 211, and the stacking rack 21 A flip support frame 212 is hingedly provided at the bottom of the stacking bin. When the lifting platform 22 drives the material to rise, the flip support frame 212 can be rotated outward to open (it is most preferred to use the material to push the flip support frame 212 to rotate and open, and of course it can also be opened by electric drive). It also includes a reset member 4 for driving the flip support frame 212 to reset after it is rotated and opened (when the material is used to push the flip support frame 212 to open, the reset member is most preferably a spring. When the flip support frame 212 is opened by electric drive, it can also be driven by a motor or an electric cylinder or an air cylinder to rotate and reset). When the top of the flip support frame 212 rotates to a horizontal state, a limit member 5 for limiting the reset angle of the flip support frame 212 is also provided on the stacking frame 21 (the limit member 5 can most preferably be a limit surface, which contacts the flip support frame 212 when it rotates, thereby preventing it from rotating excessively), and a pressure block 6 for flattening the material is also provided on the side wall of the stacking bin 211 on the stacking frame 21, and the pressure block 6 is guided and slid on the stacking frame 21 in the vertical direction.

[0029] With the above technical solution, during use, the conveyor belt 11 can transport the material above the lifting platform 22. At this time, the lifting platform 22 rises, and the flipping support frame 212 rotates outward to open, thus creating a passage to allow the material on the lifting platform 22 to enter the stacking bin 211. At this time, the reset member 4 drives the flipping support frame 212 to rotate back to its original position, so that the flipping support frame 212 supports the bottom of the material to prevent it from falling. The limiting member 5 keeps the flipping support frame 212 in a supporting state. Further, when the second group of materials enters the stacking bin 211, the second group of materials will support on the bottom of the first group of materials, and the flipping support frame 212 supports on the bottom of the second group of materials. Repeating this operation can achieve stacking. And when stacking, the pressing block 6 will press on the top of the uppermost material to prevent the material from shifting or toppling. Further, by driving the feeding pusher 32 to slide through the pusher driving member 33, the material can be pushed onto the placing table 31.

[0030] On the stacking rack 21, there are guide rods 213 arranged in the vertical direction and sliders 214 that slide along the guide rods 213. The pressing block 6 is arranged on the slider 214 and extends into the stacking bin 211. At the bottom of the slider 214, there is an elastic buffer member 215 (the elastic buffer member 215 can be products such as springs and elastic pads) that elastically buffers and contacts the stacking rack 21 when the slider 214 slides downward. The slider 214 facilitates the installation of the pressing block 6. During use, due to gravity, the slider 214 can slide downward relatively to press the pressing block 6 on the material. When the material is taken away, the slider 214 will automatically slide downward due to gravity. The elastic buffer member 215 can prevent the slider 214 from making hard contact with the stacking rack 21 when sliding downward, thus playing a protective role.

[0031] There are two sets of the conveyor belts 11 arranged oppositely. Each set of the conveyor belts 11 includes a flat conveyor belt I 111 and a conveyor belt II 112 erected on one side of the conveyor belt I 111. The flat conveyor belt I 111 can play a role in supporting and main transportation, and the conveyor belt II 112 can assist the conveyor belt I 111 in transportation. And the conveyor belt II 112 moves together with the conveyor belt I 111, which can further prevent the material from skewing.

[0032] There are also two conveyor motors 12. Each conveyor motor 12 corresponds to a set of conveyor belts 11. A bevel gear 7 is sleeved on the output shaft of the conveyor motor 12. The end of the output shaft is in linkage cooperation with the conveyor belt II 112, and the bevel gear 7 is in linkage cooperation with the conveyor belt I 111. Each set of the conveyor belt I 111 and the conveyor belt II 112 is driven by the same conveyor motor 12, which can prevent a speed difference from being generated during startup and make it more stable during operation. The specific structure of the conveyor belt belongs to the prior art and will not be introduced in detail in this article.

[0033] On the feeding station 1, there are two sets of oppositely arranged mounting plates 8. An adjusting screw rod 9 for adjusting the distance between the two is provided on the mounting plates 8. Two conveyor belts 11 are respectively arranged on the corresponding mounting plates 8, and two conveyor motors 12 are also arranged on the corresponding mounting plates 8. By adjusting the mounting plates 8, the distance between the two conveyor belts 11 can be adjusted, and there is no need to separately adjust the conveyor belts 11, making it more convenient during adjustment.

[0034] The placing table 31 is guided and slid on the pushing station 3. A guiding opening 10 is provided on the placing table 31, and the guiding opening 10 is arranged in a constricted shape. The guiding and sliding of the placing table 31 enables its front and rear positions to be relatively adjusted, and the placing table 31 can be slid to correspond to the guiding opening 10, facilitating subsequent material pushing, with stronger practicability. The guiding opening 10 can play a guiding role during material pushing and can further prevent the material from skewing.

[0035] A abutting surface 20 is further provided on the placing table 31 (most preferably, a abutting block is provided on the placing table 31, and the abutting surface 20 is arranged on the abutting block). The loading pusher 32 includes a mounting frame 321, a left arm 322, and a right arm 323. The left arm 322 is guided and slid in the mounting frame 321 in the vertical direction, and further includes a left arm driving member 324 for driving the relative expansion and contraction of the left arm 322 (the left arm driving member is most preferably an electric cylinder or a cylinder, and of course, a motor can also be used). The right arm 323 is located above the abutting surface 20. The pusher driving member 33 can drive the overall sliding of the mounting frame 321, so that the left arm 322 can abut the material against the abutting surface 20, thus achieving a correcting effect. Further, the right arm 323 being higher than the abutting surface 20 can avoid being touched during movement, and the left arm 322 can expand and contract relatively, making it applicable to pushing materials of different heights.
