Description

Technical Field

[0001] This utility model relates to the field of mechanical structure of shoe material punching machines. 。 Background Technology

[0002] A shoe material punching press is a device used to punch and cut shoe material parts into the required shapes from a sheet of shoe material. A common shoe material punching press structure includes a punching worktable on which the sheet of shoe material is laid and a punching lifting assembly mounted above the punching worktable. There is a punching space between the punching lifting assembly and the punching worktable for the shoe material to enter. The shoe material punching operation is operated by at least one person. First, the shoe material is flattened and pulled into the punching space and aligned with the punching position of the shoe material, or the punching pattern is placed on the punching position on the upper surface of the shoe material. Then, the person removes both hands from the shoe material and raises them to the upper side of the punching lifting assembly to press the punching buttons on both sides (both hands must be pressed at the same time to prevent the person's hands from being injured by the punching if they are not removed in time). After the punching lifting assembly presses down to complete the punching, it immediately rises, and the person can pull out the shoe material and take out the punched part. Then, the above operation steps are repeated.

[0003] As can be seen from the above description, the working efficiency of existing mechanical structures is limited and difficult to improve, manual operation poses safety hazards, and production efficiency is difficult to improve. In view of this, the inventor of this case is committed to research and improvement, thus this case came into being. Utility Model Content

[0004] The purpose of this invention is to provide an automatic flattening and conveying shoe material punch press suitable for the automatic flattening and conveying of long rolls of shoe materials to improve production efficiency. 。

[0005] To achieve the above objectives, the technical solution of this utility model is: an automatic flattening and conveying shoe material punching press, characterized in that it includes a conveyor line with a track conveyor structure and a punching lifting assembly spanning and connecting both sides of the conveyor line. A punching space is formed between the punching lifting assembly and the conveyor line. The punching lifting assembly is located in the middle section of the conveyor line. The conveyor line has a flattening conveying section on the side corresponding to the input punching lifting assembly and a finishing output section on the side corresponding to the output punching lifting assembly. The flattening conveying section is provided with a pre-flattening structure to handle unevenness that may occur during the conveying of rolled shoe materials. The input side of the punching space is provided with a pressing structure, and the output side is provided with a pre-tightening roller structure. The pressing structure and the pre-tightening roller structure are used to flatten the shoe materials during punching. The finishing output section is a section that can accommodate multiple manual operations.

[0006] Furthermore, the pre-leveling structure includes a fixed crossbeam frame spanning across the conveyor line and fixedly connected at both ends to the two sides of the conveyor line, and a pre-leveling crossbar. The pre-leveling crossbar is connected to the bottom of the fixed crossbeam frame through a first lifting guide assembly and a first lifting drive assembly. The pre-leveling crossbar can be raised and lowered by the first lifting drive assembly to adjust the distance between it and the track surface on the conveyor line.

[0007] Furthermore, a long rotating cylinder is provided along the length of the side of the pre-leveling crossbar facing the conveyor belt. The long rotating cylinder is sleeved on a round rod that is fixed and suspended at both ends on the pre-leveling crossbar. The inner diameter of the long rotating cylinder is larger than the outer diameter of the round rod.

[0008] Furthermore, the pressing structure includes a pressing and fixing crossbeam frame spanning across the conveyor line and fixedly connected at both ends to both sides of the conveyor line, and a pressing crossbar. The pressing crossbar is connected to the lower part of the pressing and fixing crossbeam frame through a second lifting guide assembly and a second lifting drive assembly. The pressing crossbar can be driven by the second lifting drive assembly to descend and apply pressure to the conveyor belt.

[0009] Furthermore, the pre-tightening roller structure includes a pre-tightening fixed beam frame spanning above the conveyor line and fixedly connected at both ends to both sides of the conveyor line, a pre-tightening crossbar connected to the pre-tightening fixed beam frame via a third lifting guide assembly and a third lifting drive assembly, and a pre-tightening roller fixedly connected at both ends to and suspended on the pre-tightening crossbar via bearing seats. A drive motor is mounted on the pre-tightening crossbar, and the output end of the drive motor is connected to the output end of the pre-tightening roller through a transmission structure to achieve transmission.

[0010] Furthermore, the stamping lifting assembly includes a multi-dimensional moving device with a horizontal traversing mechanism and a vertical lifting mechanism, as well as a stamping mold component that can be fixedly installed and detached from the multi-dimensional moving device.

[0011] Furthermore, a waste sorting hopper is provided at the output end of the conveyor line.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. The conveyor belt structure enables automatic conveying of shoe materials, with the conveyor positioning paused for punching. The conveyor line has a flat conveying section, which can be set for a longer length and is suitable for automatic conveying of shoe materials in long rolls, thus improving conveying efficiency. 2. The pre-flattening structure on the flat conveying section can be used for pre-flattening and preparing the shoe materials before conveying, avoiding significant unevenness and bulges in longer shoe materials that could affect subsequent processes. 3. The pressing and pre-tightening roller structures on both the entry and exit sides of the punching space ensure that the shoe materials in the punching section are completely flat. This structure avoids inconsistencies in the punched shoe material parts caused by incomplete flattening during conveying. 4. The automated conveying, positioning, punching, and punching lifting assembly significantly improves the utilization rate and punching efficiency of shoe materials to meet the production needs of large orders. Furthermore, its automation eliminates the safety hazards associated with manual operation. 5. The sorting and output section provides space for manual operation, allowing multiple people to work and improving efficiency. 6. The mechanical structure of this invention enhances the automation performance and multi-functionality of the machine, ensuring stable, efficient, and reliable operation. Attached Figure Description

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] This embodiment discloses an automatic flattening and conveying shoe material punching press, such as Figure 1 As shown, it mainly includes a conveyor line 1, a stamping and lifting assembly 2, a pre-leveling structure 3, a pressing structure 4, and a pre-tightening roller structure 5, etc. The structural settings of each part and the positional connection relationship between them are described in detail below with reference to the attached drawings.

[0026] The conveyor line 1, such as Figure 1 As shown, a conveyor line with a tracked conveyor structure includes a machine tool 11 extending in the conveying direction, a track 12 wound around the machine tool, and a track drive mechanism (not visible in the figure, using existing track drive technology, not disclosed in detail here, but without affecting the clear understanding of the technical solution of this embodiment) installed on the machine tool. The conveyor line 1 can be divided into an intermediate section 13, a flat conveying section 14 facing the conveying input direction, and a sorting output section 15 facing the conveying output direction.

[0027] The stamping lifting assembly 2, such as Figure 1 As shown, the machine tool 11 is mounted across both sides of the conveyor line 1 and corresponds to the middle section 13 of the conveyor line 1. The stamping lifting assembly 2 forms a stamping space between the upper and lower parts of the conveyor line 1. The flattening conveying section 14 corresponds to the input side of the stamping lifting assembly 2, and the finishing output section 15 corresponds to the output side of the stamping lifting assembly 2.

[0028] The pre-leveling structure 3 is installed on the leveling conveying section 14, and can be positioned close to the input end. It is used to correct unevenness that occurs during the conveying of rolled shoe materials, such as... Figure 1 and Figure 2As shown, the pre-leveling structure 3 disclosed in this embodiment includes a fixed crossbeam frame 31 spanning across the conveyor line 1 and fixedly connected at both ends to the machine tools 11 on both sides of the conveyor line 1, and a pre-leveling crossbar 32. The pre-leveling crossbar 32 is connected to the bottom of the fixed crossbeam frame 31 through a first lifting guide assembly 33 and a first lifting drive assembly 34. The first lifting guide assembly 33, as shown in the figure, is a structure of guide rod and guide bushing, and can be provided with at least two sets to achieve balanced guidance. The first lifting drive assembly 34 can be driven by a drive cylinder or by a structure of motor and lead screw and lead screw nut (existing technology structure). Thus, the pre-leveling crossbar 32 can be raised and lowered by the first lifting drive assembly 34 to adjust the distance between it and the surface of the track 12 on the conveyor line 1. This distance is usually set according to the thickness of the shoe material laid on the track 12. When conveying, the pre-leveling crossbar 32 is adjusted to a suitable height, and the shoe material being conveyed forward will be leveled by the pre-leveling crossbar 32, thereby achieving the effect of the structure setting.

[0029] Based on the most basic fixed crossbeam frame 31 directly leveling structure, this embodiment can further improve the pre-leveling effect, such as... Figure 2 As shown, a long rotating cylinder 35 is provided along the length of the pre-leveling crossbar 32 facing the conveyor belt 12 of the conveyor line 1. The long rotating cylinder 35 is sleeved on a round rod 36 that is fixed and suspended on the pre-leveling crossbar 32 at both ends. The inner diameter of the long rotating cylinder 35 is larger than the outer diameter of the round rod 36. This structure allows the long rotating cylinder 35 to fall under gravity and press on the shoe material conveyed on the conveyor belt 12 by the inner diameter of the long rotating cylinder 35 being larger than the outer diameter of the round rod 36. Furthermore, due to its larger diameter, it can self-adjust and rotate during the conveyor belt 12 operation, thus achieving better flattening of the shoe material surface without affecting the forward conveying.

[0030] The pressing structure 4, such as Figure 1 and Figure 3 As shown, the preload roller structure 5, corresponding to the input side of the stamping space, is as follows: Figure 1 and Figure 4 As shown, corresponding to the output side of the stamping space, the pressing structure 4 and the pre-tightening roller structure 5 work together to achieve flatness of the shoe material during stamping. This structural setting further improves the flatness and stability of the shoe material segment being stamped, and can better avoid the problem of inconsistent size deviations in the stamped shoe material parts caused by incomplete flatness of the shoe material during feeding. The structural setting disclosed in this embodiment is as follows:

[0031] The pressing structure 4 is as follows Figure 1 and Figure 3As shown, it includes a pressing and fixing crossbeam frame 41 spanning across the conveyor line 1 and fixedly connected at both ends to the machine tools 11 on both sides of the conveyor line 1, and a pressing crossbar 42. The pressing crossbar 42 is connected to the lower part of the pressing and fixing crossbeam frame 41 through a second lifting guide assembly 43 and a second lifting drive assembly 44. In this embodiment, the second lifting guide assembly 43 and the second lifting drive assembly 44 can have the same structural configuration as the first lifting guide assembly 33 and the first lifting drive assembly 34. The following structural components with the same function can also have the same structure. Here, the pressing crossbar 42 can be driven by the second lifting drive assembly 44 to descend and apply pressure to the conveyor line 1 track 12.

[0032] The pre-tightening roller structure 5 is as follows Figure 1 and Figure 4 As shown, the system includes a pre-tightening fixed crossbeam frame 51 spanning above the conveyor line 1 and fixedly connected at both ends to machine tools 11 on both sides of the conveyor line 1; a pre-tightening crossbar 54 connected to the pre-tightening fixed crossbeam frame 51 via a third lifting guide assembly 52 and a third lifting drive assembly 53; and a pre-tightening roller 55 fixedly connected at both ends to and suspended on the pre-tightening crossbar 54 via bearing seats. A drive motor (not visible in the figure) is mounted on the pre-tightening crossbar 54. The output end of the drive motor and the output end of the pre-tightening roller 55 are connected through a transmission structure (not visible in the figure, but a conventional transmission technology structure can be used) to achieve transmission.

[0033] During the conveying and punching process, the track 12 conveys the next punching section to the corresponding punching space. The track 12 pauses operation. At this time, the pressing crossbar 42 of the pressing structure 4 is driven to descend and fix the shoe material by the second lifting drive assembly 44. At the same time, the pre-tightening roller 55 of the pre-tightening roller structure 5 is driven to descend and approach the shoe material by the third lifting drive assembly 53. Then, the pre-tightening roller 55 rotates under the drive of its drive motor, rolling the shoe material in the output direction to pull the shoe material, thereby achieving a further flattening effect on the current section. After flattening, the punching lifting assembly can perform the punching work. After the punching of this section is completed, the pressing structure 4 and the pre-tightening roller structure 5 immediately rise and contact the pressing, and the track resumes operation to convey the shoe material to the next punching section.

[0034] To improve the efficiency of die-cutting and the utilization rate of shoe materials, the die-cutting lifting assembly 2 can be further improved to include a multi-dimensional moving device (not visible in the figure, the specific mechanical structure can be referred to the technical structure of existing multi-dimensional moving devices, which can be easily obtained by those skilled in the art) and a die-cutting model component that can be fixedly installed and detached and mounted on the multi-dimensional moving device. If the system is set, the die-cutting position can be automatically adjusted to carry out continuous die-cutting work, thereby achieving the above-mentioned effect.

[0035] As shown in the figure, the sorting output section 15 has sections on both sides of its track 12 that can accommodate multiple manual operations. For the high-efficiency punching operation of the stamping lifting assembly 2, multiple manual sorting and die-cut shoe material parts are arranged on both sides of the sorting output section 15, which can improve sorting efficiency. The sorted shoe material waste can be transported to the output end by the operation of the track 12. The output end of the conveyor line 1 is equipped with a waste sorting hopper for receiving and accepting waste materials, facilitating waste collection and cleaning.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
