[0045] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0046] To further improve the efficiency of changing the lower template of a bag-applying machine, one embodiment of this application provides a bag-applying machine and a quick-release and disassembly structure for the lower template of the bag-applying machine.
[0047] See Figures 1-3 This mainly reflects the lower template part related to the improvement of this application. As for other parts of the bag-applying machine, they can be implemented in conjunction with existing technologies. For example, the bag-applying machine includes a base 100, a lower template 200 and a drive mechanism 300 installed on the base 100. The base 100 includes a bottom plate 110 and a top frame 120. The lower template 200 can adopt an integral or split structure. The embodiments of this application take a split structure as an example, that is, the lower template 200 includes multiple plates. As for each plate itself, it can adopt an integral or split structure. When adopting a split structure, it can include a working part located on the rear side and cooperating with the bag-shaped fabric, and a reinforcing part fixedly connected to the working part and extending further forward.
[0048] Taking a three-plate body as an example, it includes a middle plate and two side plates. The middle plate is centrally located and includes a first working part 210 and a first reinforcing part 211 that are fixed to each other. The middle plate as a whole can move relative to the base 100 in a first direction.
[0049] Two side plates are arranged on both sides of the middle plate along the second direction and can move relative to the base 100 along the second direction. The left side plate includes a second working part 220 and a second reinforcing part 221 that are fixed to each other, and the right side plate includes a third working part 230 and a third reinforcing part 231 that are fixed to each other.
[0050] The terms "left" and "right" here are used for ease of description and are relative concepts; either side can be the left, and the other side the right. The base 100 and each component have opposing front and rear sides. Figure 1 The first direction X extends along the front and rear directions, and the second direction Y is perpendicular to the first direction X and is also horizontal in the bag-applying machine direction. The lower template 200 is located on the rear side of the base 100.
[0051] In operation, the lower template 200 supports the inner edge of the bag-shaped fabric to be folded. When the lower template 200 needs to be removed to complete the folding, to avoid being obstructed by the narrowing bag opening or blocked by the stop, the relative movement of multiple plates causes the width of the lower template 200 to narrow. (Comparison) Figure 1 , Figure 3 As can be seen, after the width of the lower template 200 is narrowed, the first working part 210 moves further forward relative to the second working part 220 and the third working part 230. The second working part 220 and the third working part 230 are respectively provided with a clearance area 228 on the opposite side, and the clearance area 228 is placed in the rear side of the first working part 210.
[0052] Each plate is slidably mounted on the base 100 via a corresponding connecting seat and linked with the drive mechanism 300. In one embodiment, the drive mechanism 300 includes a cylinder 310 and a connecting rod 320 mounted on the base 100. To guide the movement of the plates, the base 100 and the corresponding connecting seat are provided with mutually cooperating guide components, such as mutually cooperating slides and guide rails. In this embodiment, a first guide component 121 is configured for the middle plate, and a second guide component 122 and a third guide component 123 are configured for the two side plates, respectively.
[0053] There are two connecting rods 320, one end of which is hinged to the piston rod of the cylinder 310, and the other end is hinged to the connecting seat of the side plate. For example Figure 2 The diagram illustrates the connecting seat 112 connected to the second reinforcing part 221. Since each side plate and its corresponding connecting seat adopts a symmetrical structure, the following description mainly uses one side plate and its connection method as an example. When the piston rod moves, it directly links the middle plate to move along the first direction X, and also causes each side plate to move along the second direction Y through the reversing of the connecting rod 320.
[0054] For precise positioning, the base plate 110 is provided with a limiting member 111, such as a threaded push rod, etc. When the movement from the center to the rear reaches the limit position, it is blocked by the limiting member 111 to implement the limit.
[0055] Further integration Figures 4-8One embodiment of this application provides a quick-release and disassembly structure for the lower template of a bag-applying machine. This structure can be configured for at least one plate from the above embodiments. For example, the connection between the left and right side plates and the base 100 both utilize the quick-release and disassembly structure of the lower template in this embodiment. The quick-release and disassembly structure specifically includes:
[0056] The connecting seat 112 is slidably mounted on the top frame 120 and linked with the drive mechanism 300. The connecting seat 112 has a positioning groove 113 and a connecting groove 114.
[0057] The plate body adopts a split fixing structure. Some partial schematic diagrams only show the second reinforcing part 221 on the front side of the plate body. The second reinforcing part 221 is detachably inserted into the connecting seat 112.
[0058] Adjusting block 224 is mounted on the plate in an adjustable position. For example, adjusting block 224 is connected to the second reinforcing part 221 by the second fastener 223. When in use, adjusting block 224 is also inserted into positioning groove 113 to determine the relative position of the plate and connecting seat 112, which can be quickly positioned.
[0059] The first fastener 222 is connected to the plate and inserted into the connecting groove 114, and fixes the second reinforcing part 221 of the plate and the connecting seat 112 together.
[0060] The shape of the connector 112 itself is not strictly limited. The rear side of the connector 112 faces the lower template, so the positioning groove 113 and the connecting groove 114 are both open at the rear. The adjusting block 224 and the first fastener 222 are respectively inserted into the positioning groove 113 and the connecting groove 114 through the rear side of the connector 112.
[0061] In this embodiment, the plate can be precisely matched with the connecting seat 112 through the adjusting block 224. When the position of the plate needs to be adjusted, it is only necessary to loosen each fastener and change the relative position between the adjusting block 224 and the second reinforcing part 221. In addition, during disassembly and assembly, the direct plugging and unplugging method is adopted. After being in place, the relative position is maintained by the first fastener 222. The overall structure is simple, the operation is convenient and quick, and the position adjustment range can be designed according to the needs.
[0062] For precise positioning, in one embodiment, the adjusting block 224 abuts against the front wall of the positioning groove 113 along the insertion direction. The widths (dimensions along the second direction Y) of the adjusting block 224 and the positioning groove 113 are adapted to each other to limit the displacement of the adjusting block 224. For example, the clearance between the adjusting block 224 and the positioning groove 113 is 0mm-0.03mm. While maintaining the relative position of the adjusting block 224 and the second reinforcing part 221, the precise relative position between the plate and the connecting seat 112 can still be guaranteed during rapid insertion and removal.
[0063] In one embodiment, the adjusting block 224 is generally a ring structure, and the hollow area of the ring structure is a strip-shaped mounting groove 227. The second fastener 223 passes through the mounting groove 227. In order to accommodate the position adjustment of the plate, the second fastener 223 and the mounting groove 227, as well as the first fastener 222 and the connecting groove 114, are all clearance fit.
[0064] For example, along the first direction X, the mating clearance between the second fastener 223 and the mounting groove 227 also corresponds to the front-to-back adjustment of the plate body relative to the connecting seat 112, such as 0.5mm-10mm.
[0065] Along the second direction Y, the mating clearance between the second fastener 223 and the mounting groove 227 also corresponds to the left and right adjustment of the plate body relative to the connecting seat 112, such as 0.5mm-3mm. The mating clearance between the first fastener 222 and the connecting groove 114 can be configured accordingly, or slightly reduced, such as 0.3mm-2mm.
[0066] Combination Figure 5 , Figure 6 To accommodate the fasteners, in one embodiment, the plate has a first connecting hole 225. The first fastener 222 includes a screw 2221 and a nut 2222 that cooperate with each other. The screw 2221 passes through the plate and the connecting groove 114 sequentially from the bottom side of the first connecting hole 225 upwards. The nut 2222 is stacked on the top surface of the connecting seat 112. Preferably, in one embodiment, the first connecting hole 225 is a countersunk threaded hole, with the head of the screw 2221 corresponding to the countersunk area. The nut 2222 is located on the top side for easier operation. When loosening the nut 2222, the screw 2221 is prevented from falling off because it is threadedly engaged with the first connecting hole 225.
[0067] In one embodiment, the plate body has a second connecting hole 226, and multiple sets of the second connecting hole 226 and the second fastener 223 are provided one-to-one, for example, two sets. Each second fastener 223 can adopt the same setting method as the first fastener, or it can adopt a screw method alone. Then the second fastener 223 has:
[0068] The head is stacked on the top surface of the connecting seat 112 for easy operation;
[0069] The rod extends downward from the head and is threaded into the second connecting hole 226 corresponding to the position.
[0070] In one embodiment, the number of one of the connecting grooves 114 and the positioning grooves 113 is two or more and they are arranged on both sides of the other; or the number of both is two or more and they are arranged in any order. Figure 5As can be seen, there is one positioning groove 113 and two connecting grooves 114 arranged on both sides of the positioning groove 113, which can take into account both connection strength and positioning accuracy.
[0071] When the plate position needs to be adjusted, loosen all fasteners, adjust the plate to the appropriate position, and then tighten all fasteners. When the plate needs to be replaced or disassembled, simply loosen the first fastener 222 to pull the plate away from the connector 112. During installation, the plate can be directly inserted until the adjusting block 224 is in place, and then the first fastener 222 can be tightened.
[0072] The quick-assembly and disassembly structure of the lower template in this application not only facilitates the disassembly, assembly, and replacement of the lower template, but also allows for adjustment of its relative position. Overall, the structure is compact, occupies little space, and has high efficiency and low cost in template changing operations.
[0073] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
