DETAILED DESCRIPTION

[0049] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] Example 1

[0051] like Figure 1~Figure 5 As shown, this embodiment provides a quantitative feeding device for a medium-sized package machine, comprising:

[0052] Rack 1;

[0053] A material receiving member 2 is arranged on the frame 1 and is used for supporting materials;

[0054] The baffle 3 is arranged on the frame 1 and located on both sides of the material receiving member 2;

[0055] A material pressing member 4 is slidably arranged on the frame 1, and the material pressing member 4 slides along the baffle 3. After the material pressing member 4 slides, it is used to press the material;

[0056] There are a plurality of first elastic members 5 , one end of which is arranged on the material pressing member 4 , and the other end is arranged on the frame 1 . The first elastic member 5 is used to provide a force for the material pressing member 4 to abut against the material.

[0057] In this embodiment, in order to solve the problem that the feeding device of the middle bag machine in the related art needs to be manually adjusted, which has a great impact on the smooth progress of the overall middle bag packaging operation and the overall low work efficiency, this solution is provided with a baffle 3 for limiting the left and right displacement of the material at the receiving plate used for the feeding operation, and a slidable pressing piece 4 is provided on the frame 1. When the loading is completed, the accumulated material is pressed by pressing the pressing piece 4 downward. It is worth noting that the pressing piece 4 in this solution is pressed down along the baffle 3. At the same time, in order to avoid the playing cards from being unable to move forward due to excessive downward pressure, the pressing piece 4 in this solution is connected with a first elastic piece 5 that can provide elastic force. By limiting the material left, right, up and down in this way, the deviation of multiple decks of playing cards during the feeding process is avoided to the greatest extent, ensuring the smooth subsequent middle bag packaging, and having extremely high practical value.

[0058] Further, the material receiving member 2 comprises:

[0059] The telescopic member 21 is arranged on the frame 1;

[0060] The supporting plate 22 is arranged on the telescopic end of the telescopic member 21, and the telescopic member 21 drives the supporting plate 22 to rise and fall;

[0061] Also includes:

[0062] The pusher 6 is movably arranged on the frame 1. After the support plate 22 moves, the pusher 6 and the support surface of the support plate 22 are located in the same plane. After the pusher 6 moves, it is used to push out the material on the support member 2.

[0063] The receiving plate 7 is arranged on the frame 1. After the supporting plate 22 moves, the supporting surface of the supporting plate 22 and the supporting surface of the receiving plate 7 are located in the same plane. The receiving plate 7 is used to receive materials.

[0064] In this embodiment, in order to convey multiple decks of playing cards to the subsequent packaging device, after the playing cards in this scheme are conveyed to the supporting plate 22 and reach the specified number, the telescopic member 21 is started, wherein the telescopic member 21 can be selected from equipment such as a motor, a cylinder or an oil cylinder. Under the action of the telescopic member 21, the supporting plate 22 rises, and at the same time, it is squeezed by the pressing member 4 to further press the material. When the supporting plate 22 moves to the same height as the pushing member 6 and the receiving plate 7, the pushing member 6 is started to guide the material on the supporting plate 22 to the receiving plate 7, and then the material is quantitatively conveyed to the subsequent packaging device.

[0065] Furthermore, it also includes:

[0066] The quantitative plate 8 is adjustably arranged on the frame 1 and is located on the feeding side of the supporting plate 22. After the supporting plate 22 moves, the quantitative plate 8 is used to block excess material.

[0067] In this embodiment, the supporting member supports N materials and during the upward sliding process, the quantitative plate 8 installed on the frame 1 is located above the (N+1)th material, and the lower surface of the quantitative plate 8 abuts against the upper surface of the (N+1)th material to limit it, thereby preventing excessive material from being conveyed to the receiving plate 7, ensuring the quantitative effect of the overall feeding, and ensuring the smooth progress of subsequent packaging operations.

[0068] Furthermore, the baffle 3 is made of transparent material.

[0069] In this embodiment, in order to timely observe the stacking state of the materials on the supporting plate 22, timely adjust the offset materials, and speed up the overall packaging efficiency, the baffle 3 in this solution is made of transparent material.

[0070] Furthermore, it also includes:

[0071] There are two conveyor belts 9, which are arranged on the frame 1. There is a conveying gap 91 between the conveyor belts 9. The conveying gap 91 is used to convey materials. The supporting plate 22, the receiving plate 7, the pressing piece 4 and the quantitative plate 8 are all located in the conveying gap 91;

[0072] The flipping member 10 is arranged on the frame 1 and is located in the conveying gap 91. The flipping member 10 is used to block and flip the material.

[0073] In this embodiment, during operation, the workpiece moves forward along the conveying gap 91 under the clamping action of the two conveyor belts 9. Taking a single pack of packaged playing cards as an example, the workpiece is in a lying state before flipping to ensure the consistency of the initial state; the two end faces of the workpiece are in compression contact with the conveyor belts 9 on both sides; the conveyor belt 9 rotates reciprocatingly on the frame 1 under the action of an external power source, and the external power source is preferably an electrically driven motor; when the workpiece moves with the conveyor belt 9, it will gradually approach the flipping member 10 until the side of the workpiece facing the moving direction is in compression contact with the arc surface on the flipping member 10; the arc surface on the flipping member 10 gives the workpiece an obstructing force, and under the continuous conveying action of the conveyor belt 9, the workpiece starts to flip with the arc surface as the origin of flipping; the workpiece stops flipping after flipping a certain angle, and the flipping angle is preferably 90°; when the workpiece stops flipping, under the action of the conveyor belt 9, the workpiece continues to move forward in the flipped state until the subsequent processing station completes the processing and output of the workpiece.

[0074] Furthermore, it also includes:

[0075] The blowing member 11 is arranged on the flipping member 10 and is located below the material. After the blowing member 11 blows air, it is used to push the material to flip.

[0076] In this embodiment, in order to further increase the turning speed of the material when passing through the turning piece 10, a blowing piece 11 for exhausting air is provided on the turning piece 10. The material will first pass over the blowing piece and then come into contact with the turning piece 10; the blowing piece 11 is started with the help of an external controller, and when the front end of the material passes over the blowing piece 11, it will come into extrusion contact with the turning piece 10. At this time, the rear end of the workpiece is just located above the blowing piece 11. At this time, the blowing piece 11 outputs gas with a certain flow rate. Under the action of the gas, the rear end of the workpiece starts to rotate upward with the contact position between the workpiece and the turning piece 10 as the origin, and then, with the help of the obstruction of the turning piece 10, the workpiece is turned over; with the help of the blowing piece 11, the workpiece completes the initial turning preparation work, further ensuring the smooth progress of the turning operation.

[0077] Further, the supporting plate 22 comprises:

[0078] The fixing portion 221 is disposed on the telescopic end of the telescopic member 21, and the fixing portion 221 has a plurality of positioning grooves 223;

[0079] The adjusting portion 222 is movably arranged on the fixing portion 221 through a threaded rod, and is used to expand the supporting area after the threaded rod is rotated;

[0080] The positioning rod 224 is disposed on the adjusting portion 222 and is plugged into and matched with the positioning groove 223 . After the adjusting portion 222 moves, the positioning rod 224 slides along the positioning groove 223 .

[0081] In the present embodiment, in order to ensure that the medium-sized packaging machine with different numbers of packages is equipped, the area size of the supporting plate 22 in the present solution can be adjusted. Specifically, the fixing plate of the supporting plate 22 in the present solution is installed on the telescopic member 21, and the corresponding rest is the adjustment part 222, wherein the adjustment part 222 is connected to the fixing part 221 by a threaded rod 225. When a larger supporting area is required, the threaded rod 225 is rotated to move it away from the fixing part 221. Correspondingly, in order to ensure that the adjusted adjusting part 222 is still in a horizontal state, the fixing part 221 in the present solution has a plurality of positioning grooves 223, and the positioning rod 224 is moved to slide along the positioning groove 223, thereby ensuring the overall horizontal state.

[0082] Furthermore, the fixing portion 221 has a plurality of avoidance grooves 2211, and further includes:

[0083] A ratchet wheel 12 is rotatably disposed on the frame 1, and the ratchet wheel 12 has a plurality of convex teeth 121;

[0084] A ratchet 13 is hingedly mounted on the frame 1. After the ratchet 13 rotates, it abuts against the end surface of one of the convex teeth 121 to prevent the ratchet 12 from reversing.

[0085] A second elastic member 14, one end of which is disposed on the pawl 13 and the other end of which is disposed on the frame 1, and the second elastic member 14 is used to provide a force for the pawl 13 to abut against the convex tooth 121;

[0086] There are several limit rods 15, each of which has a mounting end 151 and a limit end 152. The mounting end 151 is arranged on the side wall of the protruding tooth 121. After the ratchet 12 rotates, the limit end 152 passes through the avoidance groove 2211 to limit the material conveying speed.

[0087] In this embodiment, since the rotation speed of the conveyor belt 9 is difficult to adjust during the conveying of the material by the conveyor belt 9, the material is excessively accumulated on the support plate 22. In order to control the overall feeding speed and avoid excessive accumulation of materials, a ratchet 12 is provided on the frame 1 in this solution, and a pawl 13 for placing the ratchet 12 on the flip is provided. The limiting rod 15 installed on the convex teeth 121 of the ratchet 12 has a certain blocking effect on the conveyed material, that is, the transmission speed of the material is reduced. At the same time, due to the pawl 13 and the ratchet 12 It is impossible to reverse. When the material stack reaches the set quantity, the limit rod 15 cannot rotate, and the subsequent material is blocked and limited. It should be noted that in order to avoid the interference between the limit rod 15 and the support plate 22 during the rotation of the ratchet 12, the support plate 22 is provided with an avoidance groove 2211 at the rotation position of the limit rod 15. At the same time, in order to avoid the material from escaping, the size of the avoidance groove 2211 is consistent with the length of the limit end 152. Through the above method, the overall practical effect is greatly improved and the overall packaging efficiency is guaranteed.

[0088] Furthermore, it also includes:

[0089] The hinged portion 16 is hingedly disposed on the limiting end 152, and after the hinged portion 16 rotates, it is used to pass through the avoidance groove 2211;

[0090] A plurality of support rods 17 are provided on the limit end 152, and the support rods 17 are used to prevent the hinged portion 16 from rotating in the direction of rotation of the ratchet wheel 12;

[0091] There are a plurality of third elastic members 18 , one end of which is disposed on the hinged portion 16 , and the other end of which is disposed on the limiting end 152 . The third elastic member 18 is used to provide a force for restoring the hinged portion 16 .

[0092] In this embodiment, in order to further ensure the limiting effect on the material, the present scheme is provided with a hinged part 16 at the limiting end 152, which lengthens the overall limiting length. At the same time, in order to ensure the limiting effect of the material when passing through the hinged part 16 and prevent the hinged part 16 from rotating with the material, the present scheme also has a support rod 17 for preventing it from rotating. The support rod 17 is located on the other side of the material passing direction. In this way, it is ensured that the hinged part 16 will not rotate with the material when passing. At the same time, when passing through the avoidance groove 2211, since there is no support rod 17 on the other side of the hinged part 16 for limiting, the hinged part 16 can rotate, thereby ensuring the rotation of the overall limiting rod 15. In summary, this way ensures the overall limiting effect, improves the overall material quantitative transportation effect, and has high practical value.

[0093] Furthermore, it also includes:

[0094] The contact surface between the flip member 10 and the material is an arc surface.

[0095] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
