Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, and in particular to a trimming device for sponge materials. Background Technology

[0002] Sponges are porous materials, usually made of synthetic materials such as polyurethane and polyvinyl chloride, but there are also natural sponges made from marine organisms. They are widely used in cleaning, liquid absorption, packaging protection, medical surgery, and industrial filtration. Sponges are known for their excellent elasticity, durability, and plasticity. They can be cut into different shapes and sizes as needed. In terms of environmental protection, natural sponges have a smaller impact on the environment as a renewable resource, while some synthetic sponges can also be recycled. In the process of manually cutting sponges, it is necessary to observe and cut at the same time to improve cutting efficiency and neatness.

[0003] Chinese Patent Publication No. CN220146152U discloses a sponge cutting device, belonging to the technical field of cutting equipment. It includes a base plate and a lifting platform installed on the top of the base plate. A mounting seat is installed on the top of the lifting platform, and a conveying mechanism is installed on the inner side of the mounting seat. A cutting mechanism is installed on the outer side of the lifting platform and on the top of the base plate. A box is installed on the outer side of the cutting mechanism and on the top of the base plate. An electric slide rail is installed on the top of the inner wall of the box. Through the setting of partition, needle plate, first electric telescopic rod and electric slide rail, the cut sponge will fall to the top of the partition. At this time, the first electric telescopic rod is activated to insert the needle plate into the sponge on the top of the partition. Then, the electric slide rail is activated to drive the first electric telescopic rod and needle plate to move, thereby coordinating with the moving speed of the conveying mechanism. The cut sponge and the sponge on the conveying mechanism can move synchronously, ensuring smooth cutting and improving cutting speed.

[0004] The aforementioned technology uses a movable cutting mechanism to cut the sponge on the conveying mechanism, which easily leads to incomplete cutting. Furthermore, it is difficult to adjust the position of the sponge before cutting and to fix its position during cutting, making it difficult to meet the requirements for sponge cutting. Therefore, this utility model discloses an edge trimming device for sponge materials to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a trimming device for sponge materials, so as to solve the problem that traditional sponge trimming devices mentioned in the background art are prone to failing to meet trimming requirements.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a trimming device for sponge materials, comprising a machine base, a cutting chamber fixed on the upper side of the machine base, a pressing assembly installed in the cutting chamber, a cutting assembly and a guide frame arranged sequentially inside the machine base and below the pressing assembly, and a combined transmission assembly for transmitting sponge materials through the cutting area of ​​the cutting assembly connected between the two ends of the machine base.

[0007] The combined transmission assembly includes two transmission rollers rotatably connected between the inner walls of both sides of the machine base and a transmission motor fixed to the outer wall of the machine base. The output end of the transmission motor is fixed to one of the transmission rollers. A wide transmission belt and a narrow transmission belt are connected between the two transmission rollers. The outer peripheral walls of the wide and narrow transmission belts are provided with mutually aligned baffles, and a cutting slit is formed between the wide and narrow transmission belts.

[0008] As a further embodiment of this utility model, the cutting assembly includes a central shaft rotatably connected between the inner walls of both sides of the machine base and a cutting motor fixed to the outer wall of one side of the machine base. The output end of the cutting motor is fixed to the central shaft, and a cutting saw blade is fixedly sleeved on the outer side of the central shaft. The cutting saw blade is located between the wide conveyor belt and the narrow conveyor belt, and the highest point of the cutting saw blade is higher than the wide conveyor belt and the narrow conveyor belt.

[0009] As a further embodiment of this utility model, the pressing assembly includes a threaded cylinder fixed to the top of the cutting chamber and two guide cylinders. Guide rods are slidably connected inside each guide cylinder, and extension plates are fixedly connected between the bottom ends of the guide rods. A lead screw is threaded inside the threaded cylinder, and a handle is fixedly connected to the top end of the lead screw. The bottom end of the lead screw is rotatably connected to the extension plate. Four connecting rods are fixedly connected to the lower side of the extension plate, and guide plates are fixedly connected between adjacent connecting rods. Both ends of the guide plates are provided with raised portions.

[0010] As a further embodiment of this utility model, the guide plate is parallel to the wide conveyor belt and the narrow conveyor belt, and the two guide plates are respectively located on both sides of the cutting saw blade.

[0011] As a further embodiment of this utility model, the guide frame is inclined, and the lowest end of the guide frame extends out of the machine platform.

[0012] As a further embodiment of this utility model, a reference plate is slidably connected between the two ends of the machine base, and a positioning bolt is threadedly connected to one side of the reference plate, the positioning bolt abutting against the outer wall of the machine base.

[0013] As a further embodiment of this utility model, the machine base is provided with scale markings corresponding to the reference plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model discloses a trimming device for sponge materials. When the transmission motor is started, the transmission motor drives the transmission roller to rotate. The transmission roller drives the wide transmission belt and the narrow transmission belt to run in a cycle. The cutting motor drives the cutting saw blade to rotate at high speed. When the sponge material passes through the cutting saw blade, it can be completely cut and separated. The debris produced by cutting passes through the gap between the wide transmission belt and the narrow transmission belt and falls into the guide frame. Under the action of gravity, the debris gathers at the bottom of the guide frame, which can be easily collected. The device has a high degree of automation and overcomes the safety hazards of manual cutting.

[0016] 2. This utility model provides a cutting device for sponge materials. Loosen the positioning bolts, move the reference plate to a suitable position so that the scale markings indicated by the moving reference plate are consistent with the standard width of the sponge material. After retightening the positioning bolts, place the sponge material on the upper side of the wide and narrow conveyor belts so that one side of the sponge material abuts against the stop boss and the other adjacent side of the sponge material abuts against the reference plate, which can ensure that the sponge material can be accurately cut.

[0017] 3. This utility model provides a trimming device for sponge materials. By rotating the handle, the handle drives the lead screw to rotate, and the lead screw drives the extension plate to rise and fall, thereby adjusting the height of the guide plate so that the pressure of the guide plate on the sponge material can be maintained within a suitable range. When the stop protrusion can push the sponge material close to the cutting saw blade, the sponge material is deformed and compacted after being squeezed by the raised part, which can prevent the sponge material from vibrating and shifting during the cutting process and ensure that the cut can be flat and aligned.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-6 This utility model provides a trimming device for sponge materials, including a machine base 1, a reference plate 11 slidably connected between the two ends of the machine base 1, a positioning bolt 12 threadedly connected to one side of the reference plate 11, and the positioning bolt 12 abutting against the outer wall of the machine base 1;

[0028] Specifically, first loosen the positioning bolt 12 so that the reference plate 11 can slide freely on the machine base 1. After sliding the reference plate 11 to the required position, tighten the positioning bolt 12 again so that the positioning bolt 12 abuts against the outer wall of the machine base 1, thereby fixing the position of the reference plate 11 and ensuring that one side of the sponge material can be in close contact with the reference plate 11 during the cutting process, so as to achieve precise cutting.

[0029] Furthermore, the machine tool 1 is provided with scale markings 13 corresponding to the reference plate 11;

[0030] Specifically, the scale mark 13 can help the operator determine the position of the sponge material and ensure its accuracy during the cutting process. When it is necessary to adjust the cutting width of the sponge material, it can be achieved by moving the reference plate 11 to the position corresponding to the scale mark 13. It is worth noting that the zero mark of the scale mark 13 is located on the plane where the cutting saw blade 43 is located. The operator can quickly and accurately set the cutting width, improve work efficiency and reduce errors.

[0031] Furthermore, a cutting chamber 2 is fixed on the upper side of the machine base 1;

[0032] Specifically, through slots are provided on both the front and rear sides of the cutting chamber 2, and a reference plate 11 is inserted in the through slots, so that the left and right positions of the reference plate 11 can be adjusted. On the other hand, the through slots also allow the sponge material to pass through the cutting chamber 2. Under the protection of the cutting chamber 2, the operator cannot approach the cutting area, reducing the safety hazards caused by human error.

[0033] Furthermore, a pressing assembly 3 is installed inside the cutting chamber 2. The pressing assembly 3 includes a threaded cylinder 31 fixed to the top of the cutting chamber 2 and two guide cylinders 32. Guide rods 33 are slidably connected inside each guide cylinder 32. An extension plate 34 is fixedly connected between the bottom ends of the guide rods 33. A lead screw 35 is threaded inside the threaded cylinder 31. A handle 36 is fixedly connected to the top end of the lead screw 35. The bottom end of the lead screw 35 is rotatably connected to the extension plate 34. Four connecting rods 37 are fixedly connected to the lower side of the extension plate 34. A guide plate 38 is fixedly connected between adjacent connecting rods 37. Both ends of the guide plate 38 are provided with raised portions 39.

[0034] Specifically, rotating the handle 36 causes the lead screw 35 to rotate, which in turn causes the extension plate 34 to rise and fall, thus adjusting the height of the guide plate 38. This allows the pressure of the guide plate 38 on the sponge material to be maintained within a suitable range. Through the squeezing action, the sponge material adheres more tightly to the cutting saw blade 43, reducing vibration and displacement during the cutting process, thereby improving the flatness and alignment of the cut. It is worth noting that the raised part 39 has an arc-shaped or inclined structure, which can gradually guide the sponge material to shrink in volume without damaging the sponge material, thus ensuring the integrity of the sponge material.

[0035] Furthermore, the guide plate 38 is parallel to the wide conveyor belt 63 and the narrow conveyor belt 64, and the two guide plates 38 are respectively located on both sides of the cutting saw blade 43;

[0036] Specifically, the parallel guide plates 38 help maintain the stability and linear movement of the sponge material during transmission, reducing possible deviation or vibration of the material during transmission. The two guide plates 38 correspond to the wide conveyor belt 63 and the narrow conveyor belt 64 respectively, and will not affect the cutting process of the cutting saw blade 43. They are suitable for sponge cutting processes of any thickness.

[0037] Furthermore, a cutting assembly 4 and a guide frame 5 are sequentially arranged inside the machine base 1 and below the pressing assembly 3. The cutting assembly 4 includes a central shaft 41 rotatably connected between the inner walls of both sides of the machine base 1 and a cutting motor 42 fixed to the outer wall of one side of the machine base 1. The output end of the cutting motor 42 is fixed to the central shaft 41. A cutting saw blade 43 is fixedly sleeved on the outer side of the central shaft 41. The cutting saw blade 43 is located between the wide conveyor belt 63 and the narrow conveyor belt 64. The highest point of the cutting saw blade 43 is higher than the wide conveyor belt 63 and the narrow conveyor belt 64.

[0038] Specifically, the cutting motor 42 drives the cutting saw blade 43 to rotate at high speed. When the sponge material passes through the cutting saw blade 43, it can be completely cut and separated. The debris generated by cutting passes through the gap between the wide conveyor belt 63 and the narrow conveyor belt 64 and falls into the guide frame 5.

[0039] Furthermore, the guide frame 5 is inclined, and the lowest end of the guide frame 5 extends out of the machine base 1;

[0040] Specifically, the debris generated during cutting can be discharged directly from the bottom of the guide frame 5 and fall into the collection container outside the machine 1, which facilitates the collection and handling of debris.

[0041] Furthermore, a combined transmission assembly 6 for transmitting sponge material through the cutting area of ​​the cutting assembly 4 is connected between the two ends of the machine base 1. The combined transmission assembly 6 includes two transmission rollers 61 rotatably connected between the inner walls of both sides of the machine base 1 and a transmission motor 62 fixed to the outer wall of the machine base 1. The output end of the transmission motor 62 is fixed to one of the transmission rollers 61. A wide transmission belt 63 and a narrow transmission belt 64 are connected between the two transmission rollers 61. The outer peripheral walls of the wide transmission belt 63 and the narrow transmission belt 64 are provided with mutually aligned material-blocking protrusions 65, and a cutting slit is formed between the wide transmission belt 63 and the narrow transmission belt 64.

[0042] Specifically, the transmission motor 62 is started, which drives the transmission roller 61 to rotate. The transmission roller 61 drives the wide transmission belt 63 and the narrow transmission belt 64 to run in a cycle. The material stop boss 65 can push the sponge material close to the cutting saw blade 43. The function of the material stop boss 65 is to prevent the sponge material from shifting during the transmission process and to ensure that the material maintains the correct position during the cutting process.

[0043] Working principle:

[0044] In use, loosen the positioning bolt 12, move the reference plate 11 to a suitable position so that the scale mark 13 indicated by the moving reference plate 11 matches the standard width of the sponge material, and then retighten the positioning bolt 12. Next, place the sponge material on the upper side of the wide conveyor belt 63 and the narrow conveyor belt 64, so that one side of the sponge material abuts against the stop boss 65, and the other adjacent side of the sponge material abuts against the reference plate 11. Start the transmission motor 62, which drives the transmission roller 61 to rotate. The transmission roller 61 drives the wide conveyor belt 63 and the narrow conveyor belt 64 to circulate. The stop boss 65 can push the sponge material closer to the cutting saw blade 43. The sponge material is deformed and compacted after being squeezed by the raised part 39, which can prevent... During the cutting process, the sponge material vibrates and shifts, ensuring that the cut is flat and aligned. At the same time, the cutting motor 42 drives the cutting saw blade 43 to rotate at high speed. When the sponge material passes through the cutting saw blade 43, it can be completely cut and separated. The debris generated during cutting passes through the gap between the wide conveyor belt 63 and the narrow conveyor belt 64 and falls into the guide frame 5. Under the action of gravity, the debris gathers at the bottom of the guide frame 5 for easy collection. It is worth noting that when cutting sponge materials of different thicknesses, the handle 36 is turned, which drives the lead screw 35 to rotate. The lead screw 35 drives the extension plate 34 to rise and fall, so that the height of the guide plate 38 can be adjusted so that the pressure of the guide plate 38 on the sponge material can be maintained within a suitable range.
