Description

Technical Field

[0001] This utility model relates to the field of computer embroidery machine technology, specifically to a multi-gold sheet slicing device. Background Technology

[0002] As people's living standards improve, they have higher requirements for the colors and patterns of clothing, and sequin embroidery on clothing, bags, and other embroidered items is becoming increasingly popular. Currently, the sequin embroidery process is generally completed by an embroidery machine and a sequin conveying device, which simultaneously transports sequins of different sizes.

[0003] Chinese utility model patent application number 201120104012.0, entitled "Multi-Gold Sheet Feeding Device," discloses a multi-gold sheet slicing device, comprising: a motor plate; a first feeding mechanism disposed on the motor plate for conveying a first gold sheet at a first height to a first cutting position; a second feeding mechanism disposed on the motor plate for conveying a second gold sheet at a second height below the first height to a second cutting position; and a slicing mechanism disposed on the motor plate, including a slicing motor and a cutting shaft, and a first cutter and a second cutter sequentially disposed on the cutting shaft; the first cutting position and the second cutting position are configured such that the center hole of the first gold sheet to be cut corresponds to the center hole of the second gold sheet; the first cutter is disposed corresponding to the first cutting position of the first gold sheet; the second cutter is disposed corresponding to the second cutting position of the second gold sheet; and the first cutter and the second cutter have a structure for sequentially cutting the first gold sheet and the second gold sheet. The multi-gold sheet slicing device further includes: a third cutter base with a third gold sheet conveying channel; a third gold sheet cover plate covering the third cutter base, the plate surface having a groove corresponding to the second shift fork head; a second cutter base on the third cutter base and having a second gold sheet conveying channel; a second gold sheet cover plate covering the second cutter base, the plate surface having a stepped structure, a first gold sheet conveying channel being provided on the higher platform of the stepped structure, and a groove being provided on the plate surface of the lower platform of the stepped structure; and a first gold sheet cover plate covering the stepped structure of the second gold sheet cover plate, the plate surface having a groove corresponding to the first shift fork head. The multi-gold sheet slicing device includes a first cutter, a second cutter, and a third cutter sequentially arranged on a cutter shaft. The three cutters sequentially cut the first, second, and third gold sheets, transferring the cutting load of cutting the three gold sheets sequentially to the cutter shaft, effectively reducing the load on the cutter shaft, reducing energy loss, and improving the working performance of the cutter shaft. The three feeding mechanisms, each controlled by a separate motor, ensure that the three gold sheets are delivered to the precise position each time, guaranteeing smooth cutting and preventing inconvenience caused by differences in the specifications of the three gold sheets. The cutter base has a conveying channel and a cover plate to ensure stability and accuracy during the gold sheet conveying process.

[0004] However, in existing technologies, to reduce the overall height of the stationary blade assembly (i.e., the three cutting blade bases and the gold sheet cover), a feeding slot is created on the cutting blade base. While this design reduces the overall height of the stationary blade assembly, since there are not many gold sheet sizes, when the gold sheet size needs to be changed, the cutting blade base needs to be replaced, which is troublesome and costly. Other existing technologies add a feeding slot structure, increasing the overall height of the stationary blade assembly. This can cause the topmost gold sheet to "fly" after cutting, affecting the quality of the gold sheet embroidery. Alternatively, the overall structure can be made thinner, but this would affect the overall product strength and the slicing effect when used with the moving blade. Therefore, the technological improvement of multi-gold sheet slicing devices has reached a dilemma. Utility Model Content

[0005] Therefore, this utility model provides a multi-gold sheet slicing device that can overcome the shortcomings of the prior art in that it is difficult to simultaneously satisfy the requirements of reducing the height of the static blade assembly and increasing the strength of the static blade assembly.

[0006] To address the aforementioned problems, this utility model provides a multi-gold sheet slicing device, including a stationary blade assembly. The stationary blade assembly comprises a first stationary blade assembly, a second stationary blade assembly, and a third stationary blade assembly arranged sequentially from bottom to top along a vertical direction. The first stationary blade assembly includes a first stationary blade and a first sheet feeding component stacked together. The second stationary blade assembly includes a second stationary blade and a second sheet feeding component stacked together. The third stationary blade assembly includes a third stationary blade and a third sheet feeding component stacked together. The first, second, and third sheet feeding components are all used to accommodate gold sheets to be fed. The first stationary blade has a first mounting position and a second mounting position. The second stationary blade assembly is mounted on the first mounting position, and the third stationary blade assembly is mounted on the second mounting position.

[0007] In some embodiments, the first mounting position and the second mounting position are arranged sequentially along the length direction of the first stationary blade.

[0008] In some embodiments, when the second mounting position is located near the front end of the first stationary blade, the second stationary blade assembly is mounted on the first mounting position, and the third stationary blade assembly is mounted on the second mounting position.

[0009] In some embodiments, the second stationary blade is detachably mounted at the first mounting position, and the third stationary blade is detachably mounted at the second mounting position.

[0010] In some embodiments, the first tablet feeding component, the second tablet feeding component, and the third tablet feeding component each have a tablet pressing groove and a shifting fork groove that extend through their thickness direction, wherein the width of the tablet pressing groove is greater than the width of the shifting fork groove.

[0011] In some embodiments, the second stationary blade near the first shift fork and the third stationary blade near the second shift fork respectively have clearance grooves for the passage of the first shift fork and the second shift fork.

[0012] In some embodiments, the multi-gold sheet slicing device further includes a sheet feeding mechanism, which includes a first fork and a second fork, wherein the first fork is driven by a first driving device and the second fork is driven by a second driving device.

[0013] In some embodiments, the first shift fork is connected to the first drive device via a first synchronous belt, and the second shift fork is connected to the second drive device via a second synchronous belt.

[0014] This utility model provides a multi-gold sheet slicing device. By separately setting independent second and third sheet feeding components in the second and third stationary blade assemblies, the change of gold sheet specifications is more convenient and quick. Only the corresponding sheet feeding components need to be replaced to meet the feeding requirements of gold sheets of different specifications. Compared with replacing the stationary blades, replacing the sheet feeding components is much less costly. In the prior art, three stationary blade assemblies are fixed in the same mounting position. When it is necessary to adjust one set of stationary blade assemblies, all stationary blade assemblies need to be disassembled and installed. Disassembly, installation, and debugging are troublesome, time-consuming, and labor-intensive. This application sets two mounting positions on the first stationary blade, and independently installs the second and third stationary blade assemblies on the first stationary blade. This allows the stationary blade assemblies to be adjusted independently. Furthermore, the two mounting positions are set one in front of the other. The second stationary blade assembly mounting position is moved backward, and the cutting part of the second stationary blade is extended forward. This not only meets the installation strength requirements but also reduces the overall height of the three stationary blades, effectively avoiding the "flying" phenomenon caused by the height difference after the top gold sheet is cut. This achieves efficient and stable operation of the slicing device and improves production efficiency. Attached Figure Description

[0025] See also Figures 1 to 8As shown in the embodiment of this utility model, a multi-gold sheet slicing device is provided, including a stationary blade assembly 1. The stationary blade assembly includes a first stationary blade assembly 101, a second stationary blade assembly 102, and a third stationary blade assembly 103 arranged sequentially from bottom to top in a vertical direction. The first stationary blade assembly 101 includes a first stationary blade 1011 and a first sheet feeding component 1012 stacked together. The second stationary blade assembly 102 includes a second stationary blade 1021 and a second sheet feeding component 1022 stacked together. The third stationary blade assembly 103 includes a third stationary blade 1031 and a third sheet feeding component 1032 stacked together. The first sheet feeding component 1012, the second sheet feeding component 1022, and the third sheet feeding component 1032 are all used to accommodate gold sheets to be fed. The first stationary blade 1011 has a first mounting position 1014 and a second mounting position 1013. The second stationary blade assembly 102 is mounted on the first mounting position 1014, and the third stationary blade assembly 103 is mounted on the second mounting position 1013. By setting independent second feeding components 1022 and third feeding components 1032 on the second stationary blade assembly 102 and the third stationary blade assembly 103, the change of gold sheet specifications is more convenient and quick. Only the corresponding feeding components need to be replaced to meet the feeding requirements of different specifications of gold sheets. Compared with replacing the stationary blades, replacing the feeding components is much cheaper. In the prior art, the three stationary blade assemblies are fixed in the same mounting position. When it is necessary to adjust one set of stationary blade assemblies, all stationary blade assemblies need to be disassembled and installed. Disassembly, installation and debugging are troublesome, time-consuming and labor-intensive. This application sets two mounting positions on the first stationary blade 1011, and independently installs the second stationary blade assembly 102 and the third stationary blade assembly 103 on the first stationary blade 1011. This allows the stationary blade assemblies to be adjusted independently. While meeting the installation strength, it can also reduce the overall height of the three stationary blades, effectively avoiding the "flying blade" phenomenon caused by the height after the uppermost gold sheet is cut. This achieves efficient and stable operation of the slicing device and improves production efficiency.

[0026] Specifically, the terms "front" and "back" in this application refer to the direction of film delivery, with the forward direction being "front" and the backward direction being "back".

[0027] In one specific embodiment, the first mounting position 1014 and the second mounting position 1013 are sequentially arranged along the length of the first stationary blade 1011. In the prior art, only one mounting position is designed, that is, three stationary blades are sequentially tilted at the front end of the first stationary blade 1011, with the fixing point at the front end of the first stationary blade 1011. This design results in the overall height of the position where the stationary blades cooperate with the moving blades of the equipment being too high. Since the gold sheet is relatively light, the problem of "flying pieces" easily occurs after slicing. If the size of the stationary blades is forcibly modified to reduce the overall height, it will greatly affect the cutting strength of the overall stationary blade assembly, leading to problems such as uneven slicing and incomplete cutting, affecting subsequent embroidery machine operations, and in severe cases, causing machine downtime for maintenance and reducing work efficiency. This application preferably sets the second mounting position 1013 behind the first mounting position 1014, allowing the second stationary blade assembly 102 and the third stationary blade assembly 103 to be installed independently, saving sheet replacement operation time and making installation and disassembly convenient and quick. Furthermore, the mounting position of the second stationary blade assembly 102 is moved backward to meet the installation strength requirements of the second stationary blade assembly 102, and the cutting mating part of the second stationary blade 1021 can be designed to be thinner to reduce the overall height of the mating part with the moving blade and solve the "flying blade" problem.

[0028] Specifically, the front and rear positions of the first mounting position 1014 and the second mounting position 1013 are the preferred configuration. However, adjusting the positions of the two mounting positions according to actual working conditions, such as having them parallel and side-by-side, is also within the scope of this application. Connecting the stationary knife assembly 1 through two bolt holes is the optimal configuration. Appropriately adjusting the connection relationship of the mounting positions, and designing one or more connection holes, are all adaptive adjustments.

[0029] In one specific embodiment, when the second mounting position 1013 is located near the front end of the first stationary blade 1011, the second stationary blade assembly 102 is mounted on the first mounting position 1014, and the third stationary blade assembly 103 is mounted on the second mounting position 1013. The optimal mounting method is to arrange the two mounting positions one after the other, moving the second stationary blade assembly 102 rearward and extending the cutting portion of the second stationary blade 1021 forward, so that the cutting portion of the second stationary blade 1021 is located in the middle of the mounting position of the third stationary blade assembly 103. This arrangement offers the highest stability and slicing efficiency. Adjusting the mounting position according to actual working conditions, such as mounting the third stationary blade assembly 103 on the first mounting position 1014 and the second stationary blade assembly 102 on the second mounting position 1013, also falls within the scope of this application.

[0030] In one specific embodiment, the second stationary blade 1021 is detachably mounted on the first mounting position 1014, and the third stationary blade 1031 is detachably mounted on the second mounting position 1013. By detachably mounting the second stationary blade 1021 on the first mounting position 1014 and the third stationary blade 1031 on the second mounting position 1013, and detachably connecting the wafer feeding component to the top of the stationary blades, this design saves more installation space and facilitates further simplification and refinement of the equipment. Alternatively, the second wafer feeding component 1022 can be mounted on the first mounting position 1014, and the third wafer feeding component 1032 on the second mounting position 1013, or other adaptive mounting methods can be used.

[0031] In one specific embodiment, the first feeding component 1012, the second feeding component 1022, and the third feeding component 1032 all have a pressing groove 6 and a shift fork groove 7 that extend through their thickness direction. The width of the pressing groove 6 is greater than the width of the shift fork groove 7. The shift fork groove 7 serves to guide the shift fork. Designing the shift fork groove 7 to be narrower to fit the shift fork better guides the movement of the shift fork and prevents it from wobbling left and right. Designing the pressing groove 6 to be wider allows it to accommodate more specifications of gold sheet structures, resulting in a higher degree of contact between the pressing groove and the gold sheet. In existing designs, the pressing groove 6 is narrower, with most of the gold sheet's central axis being a hole, leading to poor contact between the pressing groove and the gold sheet and poor pressing effect. During the shift fork's retraction process, the gold sheet will retreat along with the shift fork, making it impossible to feed the sheet smoothly.

[0032] In one specific embodiment, the second stationary blade 1021 near the first shift fork 201 and the third stationary blade 1031 near the second shift fork 202 each have a clearance groove 5 for the shift fork to pass through. By providing clearance grooves 5 at the bottom of the stationary blades to allow the shift fork to pass through, the overall height of the equipment can be effectively reduced, avoiding the "flying blade" problem.

[0033] In one specific embodiment, the multi-gold sheet slicing device further includes a sheet feeding mechanism 2, which comprises a first fork 201 and a second fork 202. The first fork 201 is driven by a first driving device 3, and the second fork 202 is driven by a second driving device 4. The first driving device 3 and the second driving device 4 can be motors or other driving devices capable of reciprocating motion. Driving the two forks with different driving mechanisms improves reliability and facilitates operation.

[0034] In one specific embodiment, the first shift fork 201 is connected to the first drive device 3 via a first synchronous belt, and the second shift fork 202 is connected to the second drive device 4 via a second synchronous belt. Using synchronous belts allows the drive mechanism to be moved rearward, providing more installation space at the front of the device. This device typically works in conjunction with a bead feeding device; due to limited installation space at the head of the embroidery machine, moving the motor rearward provides more installation space for other equipment.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
