Description

Technical Field

[0001] This invention belongs to the field of cutting machine equipment, and particularly relates to a double-sided feeding precision four-column cutting machine. Background Technology

[0002] A cutting machine is a hydraulic cutting device used in light industrial processing.

[0003] A cutting machine is a machine that uses the force of machine motion to press a die to punch and process non-metallic materials. It is suitable for non-metallic materials such as foam, cardboard, textiles, plastics, leather, rubber, packaging materials, flooring materials, carpets, fiberglass and cork. The die uses the punching pressure generated by the machine to cut the material.

[0004] Existing cutting machines cannot achieve synchronous double-sided feeding or have an unreasonable feeding structure, which affects processing efficiency. They also cannot automatically unload after cutting, further affecting processing efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a double-sided feeding precision four-column cutting machine to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] The purpose of this invention is to provide a double-sided feeding precision four-column cutting machine, which aims to solve the problems of existing cutting machines that cannot achieve synchronous double-sided feeding or have an unreasonable feeding structure, and that cannot automatically unload after cutting.

[0007] This invention is implemented as follows: a double-sided feeding precision four-column cutting machine includes a main body and further includes: feeding plates, one of which is slidably mounted on each side of the main body; a transmission mechanism for driving the two feeding plates to move synchronously closer or further apart is also mounted on the lower part of the main body; a cutting mechanism, which is mounted on the upper part of the main body and is used to cut the raw material placed on the feeding plates when the two feeding plates are close together; and a feeding mechanism, which is also mounted on the cutting mechanism and is used to block the raw material after the cutting mechanism has cut it and when the two feeding plates are moving apart, thereby causing the raw material to slide off the two feeding plates.

[0008] A further technical solution includes a transmission mechanism comprising a transmission column, a connecting rod, a push-pull rod, a rotating disk, and a rotary motor. A rotary motor is fixedly mounted on the lower part of the main body of the equipment. A rotating disk is fixedly mounted on the output end of the rotary motor. Two push-pull rods are rotatably connected to the rotating disk. A connecting rod is hinged to the end of each push-pull rod away from the rotating disk. A transmission column is fixed to the lower side of each of the two feeding plates. The ends of the two connecting rods away from the push-pull rods are respectively fixedly connected to the two transmission columns. When the rotary motor drives the rotating disk to rotate, the push-pull rods transmit power to the entire assembly consisting of the connecting rod, transmission column, and feeding plates, thereby causing the two feeding plates to move closer or further apart synchronously.

[0009] A further technical solution is that the two push-pull rods are arranged symmetrically on the rotating disk; two arc-shaped grooves are centrally symmetrically opened on the rotating disk, and arc-shaped rods are installed and fixed in the arc-shaped grooves. An elastic buffer block is installed and fixed at each end of the arc-shaped groove. A slider is provided on the arc-shaped rod for damping sliding, and the slider is also slidably connected to the arc-shaped groove. A connecting shaft is rotatably installed at the end of the push-pull rod away from the connecting rod, and the connecting shaft is fixed on the slider.

[0010] A further technical solution is that multiple pins and multiple slots that cooperate with the pins are installed at the ends of the two feeding plates that are close to each other. The pins and slots at the same end of the feeding plate are evenly staggered, and the pins and slots on one feeding plate can cooperate with the pins and slots on the other feeding plate.

[0011] A further technical solution includes a cutting mechanism comprising a cutting mounting plate, guide sleeves, guide rods, a connecting plate, a first hydraulic telescopic cylinder, and a cutting die. A first hydraulic telescopic cylinder is fixedly mounted on the upper part of the main body of the equipment. A cutting mounting plate is fixedly mounted on the end of the telescopic spindle of the first hydraulic telescopic cylinder. A cutting die is detachably mounted on the lower side of the cutting mounting plate. The first hydraulic telescopic cylinder is used to support the entire assembly formed by the cutting mounting plate and the cutting die, and to drive the entire assembly to rise and fall. Multiple guide sleeves are also circumferentially distributed and fixed on the outer side of the first hydraulic telescopic cylinder on the main body of the equipment. Guide rods slide within the guide sleeves. A connecting plate is fixedly mounted on the upper end of each guide rod, and the lower ends of each guide rod are connected and fixed to the cutting mounting plate.

[0012] In a further technical solution, the feeding mechanism is installed at both ends of the lower side of the cutting mounting plate. The feeding mechanism includes a baffle plate and an elastic telescopic rod. The elastic telescopic rod is detachably fixed to the lower side of the cutting mounting plate, and the lower end of the elastic telescopic rod is detachably fixed with an elastic telescopic rod.

[0013] A further technical solution also includes a ventilation and purification mechanism, which includes an air distribution pipe, a second hydraulic telescopic cylinder, an air extraction pipe, and an air extraction and filtration device. An air distribution pipe is located on one side between the two feeding plates, and the air distribution pipe has multiple air holes. A second hydraulic telescopic cylinder is fixed to the side of the air distribution pipe away from the air holes. The cylinder body of the second hydraulic telescopic cylinder is fixed to the main body of the equipment. The second hydraulic telescopic cylinder is used to support the air distribution pipe and control its lifting and lowering. The air extraction and filtration device is fixed to the main body of the equipment and is connected to the air distribution pipe through the air extraction pipe. The air extraction and filtration device is used to create negative pressure in the air holes through the air extraction pipe and the air distribution pipe, thereby ventilating and purifying the air in the cut-off area.

[0014] In a further technical solution, a material receiving guide groove is provided below the cutting mechanism. The bottom of the material receiving guide groove is inclined downward on one side. The lower end of the bottom of the material receiving guide groove corresponds to the side opening of the material receiving guide groove. A finished product collection groove is provided below the opening of the material receiving guide groove.

[0015] A further technical solution is that the main body of the equipment includes an equipment base, a lower column, and an equipment platform; an equipment platform is fixed on each side of the receiving guide groove, and a lower column is fixed on the lower side of the equipment platform, with the lower end of the lower column fixed to the equipment base.

[0016] In a further technical solution, the main body of the equipment also includes a slide rail, and the slide rail is fixedly installed on the upper side of the equipment platform. The feeding plate is anti-sliply installed on the slide rail. The equipment platform is also provided with an movable opening for the transmission column to pass through, and the transmission column and the movable opening are slidably connected. The rotary motor is fixed on the lower side of the receiving guide groove.

[0017] This invention provides a double-sided feeding precision four-column cutting machine. Through the arrangement of two feeding plates and a transmission mechanism, the transmission mechanism can drive the two feeding plates to move synchronously closer or further apart, thereby achieving double-sided feeding and cutting, improving processing efficiency. The cutting mechanism can cut the raw material placed on the feeding plates when the two feeding plates are close together, achieving simultaneous cutting of double-sided feeding. Furthermore, the unloading mechanism can block the raw material after the cutting mechanism has cut it and when the two feeding plates are moving apart, causing the raw material to slide off the two feeding plates, achieving automatic unloading, further improving processing efficiency and reducing the labor intensity of workers.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1 and 3As shown, a double-sided feeding precision four-column cutting machine according to an embodiment of the present invention includes a main body of the equipment and further includes:

[0031] Feeding plate 9, one feeding plate 9 is slidably installed on each side of the main body of the equipment, and a transmission mechanism for driving the two feeding plates 9 to move closer or further away synchronously is also installed at the lower part of the main body of the equipment.

[0032] A cutting mechanism is installed on the upper part of the main body of the equipment. The cutting mechanism is used to cut the raw materials placed on the feeding plates 9 when the two feeding plates 9 are brought together.

[0033] The material feeding mechanism is also installed on the cutting mechanism. The material feeding mechanism is used to block the material after the cutting mechanism has cut the material and the two feeding plates 9 are far apart, so that the material slides off the two feeding plates 9.

[0034] In this embodiment of the invention, the arrangement of two feeding plates 9 in conjunction with a transmission mechanism allows the transmission mechanism to drive the two feeding plates 9 to move closer or further apart synchronously, thereby achieving double-sided feeding and cutting, and improving processing efficiency. The cutting mechanism can cut the raw material placed on the feeding plates 9 when the two feeding plates 9 are close together, achieving simultaneous cutting of double-sided feeding. Furthermore, the unloading mechanism can block the raw material after the cutting mechanism has cut it, and when the two feeding plates 9 are moving apart, causing the raw material to slide off the two feeding plates 9, achieving automatic unloading, further improving processing efficiency and reducing the labor intensity of workers.

[0035] like Figure 1 , 3 As shown in Figure 7, in a preferred embodiment of the present invention, the transmission mechanism includes a transmission column 18, a connecting rod 19, a push-pull rod 20, a rotating disk 21, and a rotary motor 28. The rotary motor 28 is fixedly mounted on the lower part of the main body of the equipment, and the rotating disk 21 is fixedly mounted on the output end of the rotary motor 28. Two push-pull rods 20 are rotatably connected to the rotating disk 21. A connecting rod 19 is hinged to the end of each of the two push-pull rods 20 away from the rotating disk 21. A transmission column 18 is fixed to the lower side of each of the two feeding plates 9. The ends of the two connecting rods 19 away from the push-pull rods 20 are respectively fixedly connected to the two transmission columns 18. When the rotary motor 28 drives the rotating disk 21 to rotate, the push-pull rod 20 transmits power to the entire assembly consisting of the connecting rod 19, the transmission column 18, and the feeding plates 9, thereby causing the two feeding plates 9 to move closer or further away synchronously.

[0036] In one embodiment, the transmission column 18 is vertically arranged, while the push-pull rod 20 and connecting rod 19 are horizontally arranged, and the two push-pull rods 20 are centrally symmetrically arranged on the rotating disk 21. Figure 4As shown, when the rotating disk 21 rotates counterclockwise, it can pull the two feeding plates 9 closer together; when the rotating disk 21 rotates clockwise, it can push the two feeding plates 9 away from each other.

[0037] In one embodiment, such as Figure 4 and 5 As shown, the rotating disk 21 has two centrally symmetrically arranged arc-shaped grooves 30. Arc-shaped rods 32 are fixedly installed within the arc-shaped grooves 30. An elastic buffer block 29 is fixedly installed at each end of the arc-shaped groove 30. A slider 31 is damped and slidably mounted on the arc-shaped rod 32, and the slider 31 is also slidably connected to the arc-shaped groove 30. A connecting shaft 33 is rotatably mounted on the end of the push-pull rod 20 away from the connecting rod 19, and the connecting shaft 33 is correspondingly fixed to the slider 31. With this arrangement, when the rotating disk 21 rotates and the push-pull rod 20 experiences uneven force, the slider 31 will slide along the arc-shaped rod 32, and the elastic buffer blocks 29 at both ends of the arc-shaped groove 30 will elastically buffer the slider 31, improving the smoothness of the feeding plate 9's movement and reducing collisions during contact, resulting in high reliability. Furthermore, limiting the damped sliding connection between the slider 31 and the arc-shaped rod 32 can further reduce the instantaneous movement rate of the feeding plate 9, i.e., avoiding direct collision between the slider 31 and the elastic buffer block 29, thus improving overall operational stability. There are no restrictions on the arc length of the arc groove 30 and the material of the elastic buffer block 29; they can be flexibly selected and set.

[0038] In one embodiment, such as Figure 7 As shown, multiple pins 34 and multiple slots 35 that mate with the pins 34 are installed at the adjacent ends of the two feeding plates 9. The pins 34 and slots 35 at the same end of the feeding plate 9 are evenly staggered, so that the pins 34 and slots 35 on one feeding plate 9 can mate with the pins 34 and slots 35 on the other feeding plate 9. This improves the consistency when the two feeding plates 9 are connected, and ensures that the feeding plates 9 have sufficient strength to meet the processing requirements of the cutting mechanism. Preferably, in order to ensure that the pins 34 and slots 35 can be connected without obstruction, the ends of the pins 34 are preferably rounded to improve the smoothness of the connection.

[0039] like Figure 1 and 3As shown, in a preferred embodiment of the present invention, the cutting mechanism includes a cutting mounting plate 10, guide sleeves 11, guide rods 12, connecting plate 13, a first hydraulic telescopic cylinder 23, and a cutting die 24. The first hydraulic telescopic cylinder 23 is fixedly mounted on the upper part of the main body of the equipment. The cutting mounting plate 10 is fixedly mounted on the end of the telescopic spindle of the first hydraulic telescopic cylinder 23. The cutting die 24 is detachably mounted on the lower side of the cutting mounting plate 10. The first hydraulic telescopic cylinder 23 is used to support the whole composed of the cutting mounting plate 10 and the cutting die 24 and to drive the whole composed of the cutting mounting plate 10 and the cutting die 24 to rise and fall. The cutting die 24 is not limited and is designed to be detachable for easy maintenance and replacement of the required model. Multiple guide sleeves 11 are also circumferentially distributed and fixed on the outer side of the first hydraulic telescopic cylinder 23 on the main body of the equipment. Guide rods 12 are slidably provided inside the guide sleeves 11. The upper ends of the multiple guide rods 12 are fixedly mounted on the connecting plate 13, and the lower ends of the multiple guide rods 12 are all connected and fixed to the cutting mounting plate 10. By setting multiple guide rods 12 and connecting plates 13, and guiding them through guide sleeves 11, the stability of the cutting installation plate 10 in lifting and lowering can be improved. This makes it easier for the die 24 to precisely cut the raw materials on the feeding plate 9 when the first hydraulic telescopic cylinder 23 drives the cutting installation plate 10 to lift and lower.

[0040] like Figure 7 and 9 As shown, in a preferred embodiment of the present invention, the feeding mechanism is installed at both ends of the lower side of the cutting mounting plate 10. The feeding mechanism includes a baffle plate 36 and an elastic telescopic rod 37. The elastic telescopic rod 37 is detachably fixed to the lower side of the cutting mounting plate 10. The lower end of the elastic telescopic rod 37 is detachably fixed with the elastic telescopic rod 37. Both the baffle plate 36 and the elastic telescopic rod 37 are detachable, so the feeding mechanism can be selected as needed. Alternatively, the feeding mechanism can be completely removed for manual feeding, making it flexible in application.

[0041] In one embodiment, after the cutting mechanism cuts the raw material and the two feeding plates 9 move away from each other, the cutting mechanism rises and controls the lower end of the baffle plate 36 to be spaced a certain distance from the upper surface of the feeding plate 9, thereby blocking the raw material through the baffle plate 36 and causing the raw material to slide off the two feeding plates 9. Furthermore, the purpose of providing the elastic telescopic rod 37 is: during cutting, the baffle plate 36 abuts against the feeding plate 9, and the extension and retraction of the elastic telescopic rod 37 facilitates the cutting process by the die 24; after cutting, the die 24 is controlled to separate from the raw material, and the elastic telescopic rod 37 extends, allowing the baffle plate 36 to block the raw material, resulting in good application effect.

[0042] like Figure 1 and 3As shown, in a preferred embodiment of the present invention, a ventilation and purification mechanism is also included. The ventilation and purification mechanism includes an air distribution pipe 17, a second hydraulic telescopic cylinder 25, an air extraction pipe 26, and an air extraction and filtration device 27. The air distribution pipe 17 is provided on one side between the two feeding plates 9. The air distribution pipe 17 has multiple air holes 16. The second hydraulic telescopic cylinder 25 is fixed on the side of the air distribution pipe 17 away from the air holes 16. The cylinder body of the second hydraulic telescopic cylinder 25 is fixed to the main body of the equipment. The second hydraulic telescopic cylinder 25 is used to support the air distribution pipe 17 and control the lifting and lowering of the air distribution pipe 17. The air extraction and filtration device 27 is fixed to the main body of the equipment and is connected to the air distribution pipe 17 through the air extraction pipe 26. The air extraction and filtration device 27 is used to generate negative pressure in the air holes 16 through the air extraction pipe 26 and the air distribution pipe 17, so as to ventilate and purify the air in the cut-off area. The suction and dust removal and purification structure of the air extraction and filtration device 27 can adopt existing disclosed technology and is not limited. In addition, the suction pipe 26 can adapt to the raising and lowering of the air distribution pipe 17; the air distribution pipe 17 facilitates negative pressure suction and dust removal and purification in the length direction through the air hole 16.

[0043] like Figure 1 As shown, in a preferred embodiment of the present invention, a receiving guide trough 3 is provided below the cutting mechanism. The bottom of the receiving guide trough 3 is inclined downward on one side. The lower end of the bottom of the receiving guide trough 3 corresponds to the side opening of the receiving guide trough 3. A finished product collection trough 1 is provided below the opening of the receiving guide trough 3. The raw materials falling from the feeding plate 9 can be collected through the receiving guide trough 3 and then guided to the finished product collection trough 1 through the receiving guide trough 3 for safe cleaning.

[0044] like Figure 1-3 As shown, in a preferred embodiment of the present invention, the main body of the equipment includes a base 2, a bottom support column 4, a lower column 5, an inclined column 6, an equipment platform 7, a slide rail 8, a top plate 14, and an upper column 15. An equipment platform 7 is fixedly installed on each side of the material receiving guide trough 3. A slide rail 8 is installed and fixedly mounted on the upper side of the equipment platform 7. The feeding plate 9 is anti-sliply mounted on the slide rail 8. The specific arrangement is as follows: Figure 2 The slide rail 8 shown includes an upper cylindrical structure and a lower strip structure, and the diameter of the cylindrical structure is greater than the width of the strip structure, which can make the feeding plate 9 slide stably and prevent it from falling off. The equipment platform 7 is also provided with an opening 22 for the transmission column 18 to pass through, and the transmission column 18 and the opening 22 are slidably connected to further improve the stability of the transmission column 18.

[0045] A lower column 5 is fixed to the lower side of the equipment platform 7, and the lower end of the lower column 5 is fixed to the equipment base 2. The finished product collection trough 1 is also fixed to the equipment base 2. A bottom support column 4 is installed and fixed to the lower side of the equipment platform 7 near the receiving guide trough 3. The bottom support column 4 is also connected and fixed to the lower column 5 through an inclined column 6. The inclined column 6 can provide auxiliary support for the bottom support column 4. An upper column 15 is fixed to the upper side of the bottom support column 4. A top plate 14 is installed and fixed across the upper end of the upper column 15. The first hydraulic telescopic cylinder 23 is fixed to the lower middle of the top plate 14, and the guide sleeve 11 passes through the top plate 14 and is fixed to its outer side. In addition, the second hydraulic telescopic cylinder 25 is fixed to the lower side of the top plate 14. The two ends of the air distribution pipe 17 are preferably slidably connected to the upper column 15 to improve the stability of the air distribution pipe 17 during lifting. The rotary motor 28 is fixed to the lower side of the receiving guide trough 3.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
