Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, and more specifically to an iron sheet / magnet feeding device for a packaging box mounting machine and the packaging box mounting machine. Background Art

[0002] As people's living standards improve, their demands for packaging boxes have become more diverse. A packaging box with exquisite appearance can greatly increase the added value of the product. On the contrary, a poor-quality packaging box will greatly affect the sales of the product. There are many ways to close the current packaging boxes. One of them is to set an iron sheet and a magnet sheet between the box body and the box cover, so that the box cover and the box body can cooperate with each other, which is convenient for opening and closing the packaging box.

[0003] In order to improve the production efficiency and yield rate of packaging boxes, a series of mechanized equipment such as automated assembly lines for processing packaging boxes have emerged. Among them, the automated placement machine is one of the production equipment specifically used for producing the above-mentioned packaging boxes with iron sheets or magnet sheets. At present, when the existing placement machine is working, the unloading of magnets or iron sheets is usually done by the bottom feeding method, that is, the iron sheets are usually taken out from the bottom of the material tube, and the horizontal reciprocating linear motion of the feeding plate arranged under the material tube is coordinated with the receiving groove structure arranged on the feeding plate, so as to realize the separation of iron sheets or magnets and the unloading and feeding. Since the shape and depth of the receiving groove on the feeding plate are usually matched with the size of the iron sheet or magnet, once the size of the iron sheet or magnet changes, the feeding plate needs to be replaced, otherwise it is easy to get stuck or take out multiple magnet sheets at a time during the unloading process, which will eventually affect the normal operation of the equipment and reduce production efficiency. Therefore, the above structure cannot adapt well to the unloading and feeding of iron sheets or magnets of different sizes.

[0004] For example, the utility model patent with publication number CN205416516U discloses an automatic magnet sticking device for printing packaging boxes, and the utility model patent with publication number CN217553276U discloses a dynamic chip sticking machine, both of which have the above-mentioned problems and shortcomings of the prior art. Summary of the invention

[0005] In order to solve the problems and shortcomings existing in the above-mentioned prior art, the utility model specifically proposes an iron sheet or magnet unloading and feeding device for a packaging box placement machine and a packaging box placement machine. When the size of the magnet or iron sheet in the unloading tube changes, there is no need to replace the entire unloading and feeding device, but the height of the conveying channel in the corresponding adjustment device. Therefore, the structure of the utility model can dynamically adapt to the unloading and feeding of magnets or iron sheets of different sizes.

[0006] In order to achieve the above-mentioned invention object, the technical solution of the utility model is as follows:

[0008] Preferably, the pressing plate is arranged on the receiving plate through a height adjustment component.

[0009] Preferably, the height adjustment assembly comprises a height adjustment column fixed on the material receiving plate, the height adjustment column is provided with a height adjustment screw, and the pressing plate is provided with a threaded hole matching the height adjustment screw.

[0010] Preferably, a groove is provided at the end of the push plate that contacts the iron sheet or the magnet.

[0012] Preferably, one end of the push plate is connected to a push cylinder, the push cylinder is fixed on a receiving plate, and the push cylinder drives the push plate to reciprocate along a conveying direction in the conveying channel.

[0013] Preferably, a material arrival sensor is provided at the material taking station.

[0014] Based on the same inventive concept, the utility model also provides a packaging box placement machine on the other hand, on which the above-mentioned iron sheet / magnet feeding device is installed.

[0015] Beneficial effects of the utility model:

[0024] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions for achieving the invention purpose of the utility model will be further described below through several specific embodiments. It should be noted that the technical solutions claimed for protection by the utility model include but are not limited to the following embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the utility model.

[0025] When the existing SMT machines are working, the magnets or iron sheets are usually unloaded by the bottom feeding method, that is, the iron sheets are usually taken out from the bottom of the material tube, and the horizontal reciprocating linear motion of the feeding plate arranged below the material tube cooperates with the receiving groove structure arranged on the feeding plate, so as to achieve the separation of the iron sheets or magnets and the unloading and feeding of the materials. Since the shape and depth of the receiving groove on the feeding plate are usually matched with the size of the iron sheet or magnet, once the size of the iron sheet or magnet changes, the feeding plate needs to be replaced, otherwise it is easy to get stuck or take out multiple magnet sheets at a time during the unloading process, which will eventually affect the normal operation of the equipment and reduce production efficiency. Therefore, the above structure cannot adapt well to the unloading and feeding of iron sheets or magnets of different sizes.

[0026] Based on this, the embodiment of the utility model proposes an iron sheet / magnet feeding device for a packaging box placement machine and a packaging box placement machine, wherein a height-adjustable conveying channel is formed in the feeding device, and when the placement machine is working, when the size of the magnet or iron sheet in the feeding tube changes, it is not necessary to replace the feeding device as a whole, and only the height of the conveying channel in the corresponding adjustment device can be used to feed magnets or iron sheets of different sizes. The utility model not only saves the manufacturing cost of the equipment as a whole, but also improves the production efficiency of the machine.

[0027] The specific structure of the iron sheet / magnet feeding device of the present invention will be explained below through specific embodiments.

[0028] Example 1

[0029] As the most basic implementation of the utility model, this embodiment discloses an iron sheet / magnet feeding device for a packaging box placement machine. Figure 1 and Figure 2 As shown, the material feeding device is composed of a material receiving plate 1, a material feeding pipe 2 and a material pushing plate 3 arranged on the material receiving plate 1, the material feeding pipe 2 is fixed on the material receiving plate 1 through a mounting seat, an opening is arranged at the bottom of the material feeding pipe 2, the opening is a material feeding port for an iron sheet or a magnet, and there is a gap between the opening and the material receiving plate 1, a material pressing plate 4 is arranged on the material receiving plate 1, and there is a gap between the material pressing plate 4 and the material receiving plate 1, and the gap between the material receiving plate 1 and the material pressing plate 4 forms a height-adjustable conveying channel 8, that is, the lower part of the material pressing plate 4 The surface and the upper surface of the receiving plate 1 form a height-adjustable conveying channel 8, and a material picking station is arranged at the end output port of the conveying channel 8. A pushing cylinder 7 is arranged on the receiving plate 1, and the pushing plate 3 is connected to the pushing cylinder 7. The pushing cylinder 7 drives the pushing plate 3 to reciprocate in the gap between the opening of the feeding pipe and the receiving plate 1 and in the conveying channel 8 along the conveying direction of the material, thereby pushing the iron sheet or magnet falling on the receiving plate 1 from the bottom opening of the feeding pipe 2 to advance to the material picking station 9 through the conveying channel 8.

[0030] As one of the implementation methods of this embodiment, the pressing plate 4 is arranged at the front side of the feeding tube 2, and the pushing plate 3 is located at the rear side of the feeding tube 2. The iron sheet or magnet in the feeding tube 2 is discharged from the bottom opening of the feeding tube 2 and falls on the receiving plate 1 below. The pushing cylinder 7 drives the pushing plate 3 to move along the material conveying direction, pushing the magnet or iron sheet on the receiving plate 1 into the conveying channel 8 located in front of the feeding tube 2. The iron sheet or magnet is further pushed forward to the end output port of the conveying channel 8, and finally reaches the material taking station, where the magnet or iron sheet is taken away by the material taking device.

[0031] As another implementation of this embodiment, the pressing plate 4 is arranged below the feeding tube 2, and a through hole is arranged on the pressing plate 4 that matches the bottom opening of the feeding tube 2. The iron sheet or magnet in the feeding tube 2 is discharged from the bottom opening of the feeding tube 2, and falls on the receiving plate 1 below through the through hole on the pressing plate 4. At this time, the magnet or iron sheet is already in the conveying channel 8, and then the pushing cylinder 7 drives the pushing plate 3 to move along the material conveying direction, pushing the magnet or iron sheet on the receiving plate 1 to move forward in the conveying channel 8, and finally being pushed to the end output port of the conveying channel 8, arriving at the material taking station, and the magnet or iron sheet is taken away by the material taking device at the material taking station.

[0032] In this embodiment, it should be noted that, in order to separate the magnets or iron sheets in the feeding tube 3, so that only one iron sheet or magnet enters the conveying channel 8 at one time of feeding, the height of the conveying channel 8 is adjusted to be slightly greater than the thickness of one iron sheet or magnet, and usually the height of the conveying channel 8 is about 1.5 times the thickness of one iron sheet or magnet. Therefore, when the pushing cylinder 7 drives the pushing plate 3 to reciprocate, it can ensure that only one iron sheet or magnet enters the conveying channel 8 at one time of feeding, and the remaining magnets or iron sheets continue to remain in the feeding tube 3.

[0033] In the embodiment depicted in the present utility model, the pressing plate 4 has two functions. One is to separate the materials, which separates the lowest magnet / iron sheet at the opening of the discharge pipe from the upper magnet / iron sheet. The distance between the pressing plate 4 and the receiving plate 1 is about 1.5 times the thickness of a magnet / iron sheet. Therefore, when the pushing plate 3 pushes the material, only one magnet or iron sheet passes through at a time, and the remaining iron sheets or magnets are blocked by it to achieve material separation. The other function is to prevent the magnet or iron sheet from warping up during the pushing process, resulting in unsmooth pushing and jamming of the material.

[0034] In the embodiment depicted in the present utility model, since the weight of the iron sheet or magnet is relatively light, in order to avoid this, a counterweight rod 10 is further provided in the feed pipe 2, and the end of the counterweight rod 10 acts on the iron sheet or magnet in the feed pipe, and the gravity of the counterweight rod 10 itself is utilized to make the material fall smoothly onto the receiving plate 1.

[0035] In the embodiment described in the present invention, when the material in the lower feeding tube 3 is a magnet, the receiving plate 1, the pressing plate 4, the pushing plate 3 and other components are usually made of non-magnetic materials such as SUS304, SUS310S, POM and the like.

[0036] Example 2

[0037] This embodiment discloses an iron sheet / magnet feeding device for a packaging box placement machine, as a preferred embodiment of the utility model, on the basis of embodiment 1, the press plate 4 is arranged on the receiving plate 1 through a height adjustment component 5. Specifically, the height adjustment component 5 includes a height adjustment column 501, the height adjustment column 501 is fixed on the receiving plate 1, and a height adjustment screw 502 is arranged on the height adjustment column 501, and a vertical plate is arranged on the press plate 4, and a plurality of threaded holes matching the height adjustment screws 502 are arranged on the vertical plate.

[0038] In the present invention, the pressing plate 4 is lifted up or moved down, and then the height adjustment screw 502 is screwed into the corresponding threaded hole on the vertical plate to adjust the height of the pressing plate 4, thereby adjusting the distance between it and the receiving plate 1 below, and finally achieving the effect of adjusting the height of the conveying channel 8.

[0039] Example 3

[0040] This embodiment discloses an iron sheet feeding mechanism for a packaging box placement machine. As another preferred embodiment of the utility model, this embodiment differs from Embodiment 2 in that the structure of the height adjustment component 5 is different. The height adjustment component 5 of this embodiment includes a height adjustment cylinder, which is fixed on the receiving plate 1. The pressing plate 4 is connected to the height adjustment cylinder. The height adjustment cylinder drives the pressing plate 4 to reciprocate up and down, adjusts the distance between the pressing plate 4 and the receiving plate 1 below, and finally achieves the effect of adjusting the height of the conveying channel 8.

[0041] Example 4

[0042] This embodiment discloses an iron sheet / magnet feeding device for a packaging box placement machine. As another preferred implementation mode of the utility model, on the basis of the above-mentioned embodiment, in order to limit the left and right displacement of the magnet or iron sheet during the forward movement, the end of the push plate 3 in contact with the iron sheet or magnet is provided with a groove 6, and the groove 6 is a V-shaped groove. In the process of pushing the material forward, the material is stuck in the V-shaped groove to achieve the effect of limiting. Therefore, based on the V-shaped groove of the push plate 3, the utility model does not make too many requirements on the width of the conveying channel 8. The width of the conveying channel 8 does not need to match the diameter of the magnet or iron sheet. The width of the conveying channel 8 only needs to allow the magnet or iron sheet to pass through. Even if the width of the conveying channel 8 is greater than the diameter of the magnet or iron sheet, the magnet or iron sheet will not shift or offset.

[0043] Example 5

[0044] The present embodiment discloses an iron sheet / magnet feeding device for a packaging box placement machine. As another preferred implementation mode of the present utility model, on the basis of the above-mentioned embodiment, a material arrival sensor is arranged at the material picking station 9, and the material arrival sensor is fixed on the receiving plate 1, and is used to detect whether the iron sheet or magnet is pushed to the material picking station 9. After the iron sheet or magnet is in place, the material picking device takes away the iron sheet or magnet, and the pushing plate 3 pushes a new iron sheet or magnet to the material picking station 9.

[0045] If it is detected that there is no iron sheet or magnet at the material taking station 9, the push plate 3 will usually push the material again. If the material is still not detected to have arrived at the material taking station, the system may issue a material shortage alarm to remind you to add material or the machine may fail.
