Description

Technical Field

[0001] The utility model belongs to the technical field of sponge processing, and in particular relates to a sponge punching machine. Background Art

[0002] Sponge is used to make and fill various products due to its unique porous structure and excellent sound absorption, heat insulation and cushioning properties. Drilling uniform holes on the sponge can not only increase the surface area of ​​the sponge and improve the filtration efficiency, but also improve its air permeability and heat insulation properties.

In addition, when the drill bit drills a hole in a thicker sponge, the sponge around the drilling position is more easily pulled and pulled, resulting in uneven edges of the holes, and even tearing and defects, which affects the filtration efficiency and durability of the sponge.

[0026] The utility model realizes the basic function of punching holes in the sponge by arranging a hollow drill bit 9 on the punching motor 8, and then arranges a primary telescopic component 6 and a secondary telescopic component 7 to drive the punching motor 8 to move up and down to complete the positioning and punching of holes in the sponge. The sum of the strokes of the two is greater than the distance difference between the gantry 3 and the feeding belt 1, and can drive the hollow drill bit 9 to stay at any position, which is sufficient to satisfy the punching of sponges of all thicknesses. There is no need to adjust the drill bits with different strokes, thereby improving the drilling efficiency; and it also enables the pressing circular plate 16 to press the pre-punched positions on the sponge in advance before the sponge is punched, so as to avoid the parts around the punching positions being affected by high-speed rotation, thereby realizing accurate, complete and high-level punching, ensuring the integrity of the holes, as well as the filtration efficiency, thermal insulation performance and durability of the sponge.

[0027] Example 2

[0028] like Figures 1 to 6 The sponge punching machine shown is used to punch holes in sponges of different thicknesses and specifications. After uniform holes are formed on the sponge, it can improve the filtration efficiency and durability when used as various filter layers and heat insulation layers, and at the same time increase the air permeability and heat insulation performance of the used material. It mainly includes a feeding belt 1, a discharging belt 2 and a gantry 3. The feeding belt 1 is used to transfer the unpunched sponge to the left, so that it moves to the bottom of the gantry 3 for punching. After punching, the feeding belt 1 continues to move to drive the punched sponge to the left to the discharging belt 2. The discharging belt 2 transfers and collects the sponge, or enters the next step of the production line that needs to be processed.

[0029] The gantry 3 is connected to the left side of the feeding belt 1, and a sensor 22 is installed on the upper left side of the gantry 3 through an extension frame 21. The sensor 22 can sense the moving position of the sponge on the feeding belt 1 until the position where the hole is to be punched on the sponge moves to below the hollow drill bit 9, and then the sensor 22 will send a signal to drive the feeding belt 1 to stop moving, and then the hole will be punched; after the hole is punched, the feeding belt 1 moves again to transfer the sponge, and the automatic hole punching action is performed in this way. A positioning frame 19 is also connected to the left side of the middle part of the gantry 3. The positioning frame 19 is located between the feeding belt 1 and the discharging belt 2, and a punching gap area 20 is left in the middle of the positioning frame 19. Due to the special soft material of the sponge, it is easy to fail to penetrate completely during punching, which leads to poor punching effect. Therefore, the position of the sponge pre-punching needs to be moved to the positioning frame 19, and the specific punching position stays in the punching gap area 20, so that the hollow drill bit 9 can penetrate the sponge through the punching gap area 20 as much as possible to ensure its punching effect. Based on the above, the setting of the extension frame 21 can align the sensor with the punching gap area 20, driving the feeding belt 1 to accurately pause at the position where the sponge pre-punching position and the punching gap area 20 overlap, ensuring accurate punching.

[0030] Example 3

[0031] like Figures 1 to 6 A sponge punching machine shown in the figure has a guide rail 4 symmetrically arranged on the left side of the upper part of the gantry 3, and a primary telescopic assembly 6 is slidably arranged between the guide rails 4, that is, the primary telescopic assembly 6, the secondary telescopic assembly 7 and the hollow drill bit 9 above it will move forward and backward together, and the structure for driving the primary telescopic assembly 6 is set as follows:

[0032] A chain groove 10 is provided on the right side of the gantry 3. The chain groove 10 generally plays a guiding role and can assist the moving parts to operate more stably. The moving end of the chain groove 10 is connected to a servo motor 12 through a connecting frame 11. A gear is provided on the output shaft of the servo motor 12, and a rack is correspondingly provided on the top of the gantry 3. The two form a gear rack assembly 13. When the connecting frame 11 is also fixedly installed on the first telescopic assembly 6, the gear can be driven to rotate by driving the servo motor 12, and then the gear will drive the connecting frame 11 and the first telescopic assembly 6 to move back and forth on the guide rail 4 under the contact and cooperation with the rack, thereby realizing the Y-axis movement of the hollow drill bit 9.

[0033] A secondary telescopic component 7 is slidably provided on the primary telescopic component 6, that is, the primary telescopic component 6 can drive the secondary telescopic component 7 to move downward, and at the same time, the secondary telescopic component 7 can also drive the punching motor 8 installed thereon to move downward again. The sum of the strokes of the two is greater than the distance difference between the gantry 3 and the feeding belt 1, and can drive the hollow drill bit 9 to stay at any position, which is sufficient to meet the needs of sponge drilling of all thicknesses. Which telescopic component to drive first can be determined according to the situation.

[0034] A punching motor 8 is slidably connected to the secondary telescopic component 7, and a hollow drill bit 9 is provided on the output shaft of the punching motor 8. When the sponge moves to the pre-punching position, the sensor will send a signal to drive the feeding belt 1 to stop rotating, and at the same time send a signal to the servo motor 12, the telescopic component and the punching motor 8. The servo motor 12 drives the hollow drill bit 9 to move forward and backward, and the punching motor 8 drives the hollow drill bit 9 to maintain high-speed rotation. At the same time, the telescopic component drives the hollow drill bit 9 to move downward to contact the sponge and pass through the sponge to complete the precise punching of the sponge.

[0035] Moreover, in order to prevent the sponge from being affected by the high-speed rotating hollow drill bit 9 when being punched, the sponge around the hole is also rolled up, driving the entire sponge to move, causing the punching process to be affected and unable to punch accurately, a clamping circular plate 16 is also set through the limit frame 15. The clamping circular plate 16 can press the pre-punched position on the sponge in advance before the sponge is punched, so as to prevent the part around the punching position from being affected by the high-speed rotation. At the same time, a transition hole 17 is connected between the clamping circular plate 16 and the limit frame 15, so that the hollow drill bit 9 can work on the sponge below it through the transition hole 17. Secondly, in order to meet the state that the clamping circular plate 16 is always located directly above the hollow drill bit 9, the limit frame 15 is installed below the secondary telescopic component 7, and then the operation of the first telescopic component 6 will drive the clamping circular plate 16 on the secondary telescopic component 7 to first compress and position the sponge, and then the operation of the secondary telescopic component 7 drives the hollow drill bit 9 driven by the punching motor 8 to move downward to complete the punching of the sponge.

[0036] Example 4

[0037] like Figures 1 to 6 The sponge punching machine shown in the figure has a first telescopic assembly 6 divided into a first telescopic frame 601, a first monorail screw rod 602 and a first mounting block 603, a second telescopic assembly 7 divided into a second telescopic frame 701, a second monorail screw rod 702 and a second mounting block 703, a connecting frame 11 is installed on the right side of the first telescopic frame 601, a first monorail screw rod 602 is provided on the left side of the upper part of the first telescopic frame 601, a first mounting block 603 is slidably provided on the first monorail screw rod 602, and the left side of the first mounting block 603 is connected to the second telescopic frame 701, that is, the first monorail screw rod 602 can drive the first mounting block 6 03 moves up and down, thereby driving the components installed on the second telescopic frame 701 to move up and down; a second monorail screw rod 702 is provided on the left side of the upper part of the second telescopic frame 701, and a second mounting block 703 is slidably provided on the second monorail screw rod 702, and the punching motor 8 is installed on the left side of the second mounting block 703, that is, the second monorail screw rod 702 can drive the second mounting block 703 to move up and down, thereby driving the punching motor 8 and the hollow electric drill to move up and down, and the strokes of the first monorail screw rod 602 and the second monorail screw rod 702 are added together, which can maximize the complete perforation of sponges of different thicknesses.

[0038] Secondly, in order to achieve stable up and down movement of the first mounting block 603 and the second mounting block 703, slide rails 14 are also provided on the left sides of the first telescopic frame 601 and the second telescopic frame 701, and the first mounting block 603 and the second mounting block 703 are respectively slidably matched with the slide rails 14, so that the first mounting block 603 and the second mounting block 703 can drive the upper components thereof to move up and down stably under the guidance of the slide rails 14, thereby preventing the inertia of the punching motor 8 from being too large, causing the up and down movement of the first mounting block 603 and the second mounting block 703 to deviate, and making it impossible to achieve accurate punching.

[0039] Example 5

[0040] Furthermore, the present embodiment is also provided with a sharpener 18 at a position below the hollow drill bit 9 on the gantry 3. When the hollow drill bit 9 has been operating for a certain period of time, the servo motor 12 can be driven to drive the first telescopic assembly 6 and the second telescopic assembly 7 to retract the hollow drill bit 9. The original position of the hollow drill bit 9 will be located above the sharpener 18. At this time, the staff operates the first telescopic assembly 6 and the second telescopic assembly 7 to drive the hollow drill bit 9 to move downward into the mold, and then drives the drilling motor 8 to drive the hollow drill bit 9 to rotate for 3-5 seconds. During this period, the hollow drill bit 9 is fully contacted with the sharpener 18 to grind the hollow drill bit 9, which can effectively remove the wear and defects on the surface of the drill bit, restore the cutting performance, and thus extend the service life of the drill bit.

[0041] It should be further explained that the output shaft of the drilling motor 8 in the present application can be set to be hollow, and after the hollow drill bit 9 moves downward to complete the drilling of the sponge, the circular sponge that has been cut off can be collected, and then discharged after being collected to a certain extent. While improving the drilling efficiency, it can also prevent such sponges from continuing to adhere to the sponge, increasing subsequent processing operations.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0043] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
