Description

Technical Field

[0001] This utility model relates to the field of garment processing machinery technology, specifically to a folding knife mechanism for a bag opening machine. Background Technology

[0002] In existing technologies, bag opening machines are widely used. Most existing bag opening machines have a material setting device, a laser cutting device, a bag folding device, and a sewing device set on the worktable. The bag folding device is fixed above the material feeding area for accessories such as the bag flap, opening fabric piece, or zipper. The material setting device slides back and forth between the bag folding device, the laser cutting device, and the sewing device. The bag opening processing involves: the material setting device sets the bag opening position, then the laser cutting device cuts the material. After cutting, the material is moved above the accessory and folded by the bag folding device. The garment is then stacked on the accessory, and finally, all parts are moved to the sewing station for sewing. However, this technology cannot achieve continuous processing and requires a high degree of manual intervention.

[0003] Chinese utility model patent CN214244833U discloses a continuous production garment pocket opening machine. Based on existing pocket opening machines, it adds a lower support plate below the pocket folding device for placing accessories such as pocket flaps, pocket fabric, or zippers. The material setting device has an upper plate mechanism that can clamp the lower support plate and move it along with the material setting device towards the sewing device. A lower support plate reset device is provided on the worktable, which can transfer the lower support plate from the upper plate mechanism to below the pocket folding device. This enables continuous processing.

[0004] In the above technical solutions, the model and size of the folding knife are relatively fixed, and the replacement of the folding knife requires the replacement of the entire unit, which is inefficient. Moreover, the folding knife is only suitable for processing a small range of bag fabric sizes. Utility Model Content

[0005] The purpose of this invention is to provide a folding knife mechanism for a bag opening machine, which solves the problems of difficult folding knife replacement and low efficiency in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A folding knife mechanism for a bag opening machine includes a base plate and a base that is slidably disposed on the base plate and can open or close with each other. Two Y-axis folding knives are respectively disposed on the two bases. A knife holder is connected to the base. The knife holder is integrally disposed with the base or separately disposed. The knife holder is provided with an outwardly protruding positioning part. The Y-axis folding knife is provided with a positioning hole. The Y-axis folding knife is sleeved with the positioning part on the knife holder through its positioning hole.

[0008] The base and the tool holder are separate. The bottom of the base is provided with a plug hole and a clamping device, and the top of the tool holder is provided with a protruding plug pin. The plug pin of the tool holder is inserted into the plug hole and fixed by the clamping device.

[0009] The pin has a recessed locking groove, and the clamping device includes a locking block and a locking block driving component, which can drive the locking block into the locking groove of the pin.

[0010] The locking block drive component is a cylinder, and the piston rod of the cylinder is connected to the locking block.

[0011] The base and the tool holder are integrally formed.

[0012] The Y-axis folding cutter includes a vertical mounting section, a horizontal bending section, and a connecting section. The connecting section protrudes outward and connects the mounting section and the bending section. The angle between the connecting section and the bending section is an acute angle of less than 70 degrees. The bending section and the connecting section are comb-shaped and are composed of evenly spaced racks. The racks and connecting sections of one Y-axis folding cutter are staggered with those of another Y-axis folding cutter.

[0013] The positioning hole of the Y-axis folding tool is located in the mounting part; the tool holder has two positioning parts, and the positioning hole of the Y-axis folding tool is correspondingly set in two.

[0014] The advantages of this utility model are as follows: 1. The Y-axis folding knife and the base or knife holder are designed with mounting parts and mounting holes, which facilitates the disassembly and replacement of the folding knife, greatly simplifying the folding knife replacement procedure and improving production efficiency; 2. The base and knife holder are separately designed, allowing for the pre-configuration of knife holders for different models of folding knives. Based on different bag fabric processing requirements, the appropriate knife holder can be quickly replaced, further improving production efficiency; 3. When the two Y-axis folding knives are closed, the connecting parts can be inserted into each other, shortening the size of the closed folding knife and accommodating bag openings of more sizes.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0021] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0022] A folding knife mechanism for a bag opening machine, such as Figure 1-4 As shown, it includes a substrate 21 and a base 22 that is slidably disposed on the substrate 21 and can open or close to each other, and two Y-axis folding blades 23 are respectively disposed on the two bases 22.

[0023] The advantage of this invention over existing technologies lies in the fact that the Y-axis folding blade 23 is detachable. For example... Figure 2 , Figure 3 As shown, the base 22 is connected to the tool holder 24, which is integrally formed with the base 22 or separately.

[0024] like Figure 2 The figure shows an embodiment in which the base 22 and the tool holder 24 are integrally formed.

[0025] The tool holder 24 is provided with an outwardly protruding positioning part 241, and the Y-axis folding knife 23 is provided with a positioning hole 235. The Y-axis folding knife 23 is sleeved with the positioning part 241 on the tool holder 24 through its positioning hole 235, and then fixed by bolts or other convenient disassembly methods.

[0026] like Figure 3 The figure shows an embodiment in which the base 22 and the tool holder 24 are set separately.

[0027] The base 22 and the tool holder 24 are separate. The bottom of the base 22 is provided with a plug hole 221 and a clamping device. The top of the tool holder 24 is provided with a protruding plug pin 242. The plug pin 242 of the tool holder 24 is inserted into the plug hole 221 and fixed by the clamping device.

[0028] Furthermore, the insertion pin 242 has a recessed snap-fit ​​groove 243, and the clamping device includes a snap-fit ​​block 222 and a snap-fit ​​block driving component 223. When the insertion pin 242 is inserted into the insertion hole 221, the snap-fit ​​block driving component 223 is activated, driving the snap-fit ​​block 222 to snap into the snap-fit ​​groove 243 of the insertion pin 242, thereby fixing the tool holder 24.

[0029] The locking block drive component 223 is usually a cylinder, and the piston rod of the cylinder is connected to the locking block 222.

[0030] The base 22 and the tool holder 24 are integrated, making it much more convenient, faster, and cheaper to replace the Y-axis folding blade 23 compared to existing technologies. The advantage of separating the base 22 and the tool holder 24 is that tool holders 24 with different models of Y-axis folding blades 23 can be prepared in advance. The tool holder 24 can be directly replaced according to the required bag fabric size, which is more convenient and efficient than directly replacing the folding blade.

[0031] The Y-axis folding knife 23 of this utility model is also different from the prior art, such as... Figure 4 As shown, the Y-axis folding blade 23 includes a vertical mounting portion 231, a horizontal bending portion 233, and a connecting portion 232. The connecting portion 232 protrudes outward, connecting the mounting portion 231 and the bending portion 233. The angle between the connecting portion 232 and the bending portion 233 is an acute angle less than 70 degrees. The bending portion 233 and the connecting portion 232 are comb-shaped, composed of evenly spaced racks 234. The racks 234 and connecting portions 232 of one Y-axis folding blade 23 are staggered with those of another Y-axis folding blade 23. Figure 1 As shown, when the two Y-axis folding blades 23 are closed, their connecting parts 232 and rack 234 are interlocked. Compared with the prior art, the outward protrusion of the connecting part 232 and the structure of the rack 234 make the dimension between the bending parts 233 of the two Y-axis folding blades 23 shorter when they are closed. This allows the processing window 34 to be made narrower and can accommodate more bag fabric processing sizes.

[0032] Furthermore, such as Figure 2 , Figure 3 As shown, the positioning hole 235 of the Y-axis folding knife 23 is provided in the mounting part 231; the tool holder 24 is provided with two positioning parts 241, and the positioning hole 235 of the Y-axis folding knife 23 is provided accordingly.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
