Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cross-cutting machines, in particular to a cross-cutting machine with a lubrication function. Background Art
[0002] Crosscutting machine is a mechanical equipment used to cut materials. Its main function is to cut the original material in the transverse direction to obtain the required size and shape. Crosscutting machine is widely used in paper processing, plastic products, metal processing and wood processing.
[0003] During the cardboard processing, the staff places the cardboard to be processed on the feeding device of the cross-cutting machine. The feeding device transports the cardboard to the cross-cutting area. When the cardboard enters the cross-cutting area, the cross-cutting knife moves at high speed and cuts the cardboard in the horizontal direction.
[0004] However, during the long processing, the long-term contact and friction between the cross-cutting knife and the cardboard will cause wear on the surface of the cross-cutting knife, which will cause burrs on the edge of the cardboard when the cross-cutting knife cuts the cardboard, resulting in reduced cardboard processing accuracy.
[0005] In view of this, we propose a cross-cutting machine with lubrication function. Utility Model Content
[0006] The purpose of the utility model is to provide a cross-cutting machine with a lubrication function to solve the problems raised in the above background technology.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cross-cutter with a lubrication function, comprising a cross-cutter body, a driving device, a tool and a lubrication assembly; an oil delivery port is provided on the cross-cutter body, an oil storage chamber and a working chamber are provided in the cross-cutter body, the oil delivery port is communicated with the oil storage chamber, the oil delivery port is used to inject lubricating oil to ensure sufficient lubricating oil in the oil storage chamber, and the oil storage chamber is communicated with the working chamber; the tool is located below the working chamber, and the lubrication assembly is located in the working chamber; the lubrication assembly is in contact with the tool; when the tool moves downward, it will drive the lubrication assembly to secrete lubricating oil to lubricate the tool, and when the tool moves upward, the lubrication assembly absorbs oil for replenishment, and when the tool moves upward, the top of the tool will squeeze the lubrication assembly to secrete lubricating oil, and when the tool moves downward, the tool is lubricated by the lubrication assembly.
[0008] Preferably, the lubrication assembly includes a one-way valve, an oil storage bag, a sponge pad and an oil pipe; the one-way valve is located between the oil storage chamber and the working chamber; the oil storage bag is located in the working chamber and is connected to the one-way valve; the sponge pad is located on both sides of the tool and is connected to the cross-cutting machine body; the oil storage bag and the sponge pad are connected through an oil pipe, and a one-way valve is provided between the oil pipe and the oil storage bag, and the one-way valve limits the flow direction of the lubricating oil so that the lubricating oil can only flow in one direction along the direction of the oil storage chamber, the oil storage bag, the oil pipe and the sponge pad, and at the same time, the backflow of the lubricating oil is avoided, the lubricating oil flows from the oil storage chamber to the sponge pad, and is fully absorbed and stored in the sponge pad, and each time the tool passes through the sponge pad, the lubricating oil adsorbed in the sponge pad will lubricate the tool, thereby improving the tool cutting efficiency and reducing tool wear.
[0009] Preferably, the oil storage bag is a rubber air bag, which has good elasticity. When the oil storage bag is squeezed by the tool, the oil storage bag squeezes out the lubricating oil into the oil pipe. When the tool and the oil storage bag are no longer in contact, the oil storage bag can quickly absorb oil from the oil storage cavity to recover, thereby achieving rapid oil replenishment to meet lubrication needs.
[0010] Preferably, the oil pipeline is a transparent hose, and the diameters at both ends of the oil pipeline are smaller than the diameter at the middle end. The oil pipeline is a transparent hose, which makes it easy to observe the content of the lubricating oil and to add the lubricating oil in time. The reduction in diameter at both ends of the oil pipeline can increase the pressure of the lubricating oil, thereby increasing the outflow rate of the lubricating oil. The increase in the diameter at the middle end of the lubricating oil can store a small amount of lubricating oil, avoiding interruption of the lubricating oil due to untimely replenishment, thereby achieving continuity of lubrication.
[0011] Preferably, there are four oil delivery pipes, which are symmetrically installed in pairs at both ends of the sponge pad to improve the oil delivery efficiency and enable the lubricating oil to quickly fill the sponge pad.
[0012] Preferably, the bottom end of the sponge pad is triangular; the sponge pad is arranged obliquely, and the triangular bottom end of the sponge pad can make the lubricating oil gradually converge during the downward flow, thereby increasing the content of the lubricating oil at the bottom and improving the lubrication content of the tool. The inclined arrangement of the sponge pad can enhance the contact area with the tip of the tool, thereby enhancing the lubrication effect on the tip of the tool and reducing tip wear.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the device drives the lubrication component to supply oil to lubricate the tool through the reciprocating motion of the tool, so that the lubrication component lubricates the surface of the tool to form a lubricating film, thereby reducing the friction and wear of the tool when cutting cardboard, improving the cutting accuracy and cutting efficiency, and extending the service life of the tool.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] During the cardboard processing, the staff places the cardboard to be processed on the feeding device of the cross-cutting machine. The feeding device transports the cardboard to the cross-cutting area. When the cardboard enters the cross-cutting area, the cross-cutting knife moves at high speed and cuts the cardboard in the horizontal direction.
[0021] During the cardboard processing, the high-frequency movement of the cross-cutter causes friction and collision with the cardboard. The accumulation of friction and collision over a long period of time will cause wear on the surface of the cross-cutter, which in turn causes the movement of the cross-cutter to no longer be smooth, causing vibration or shaking during the cutting process, resulting in burrs on the edge of the cardboard, resulting in reduced cardboard processing accuracy and quality. At the same time, wear will reduce the sharpness of the cross-cutter, thereby reducing cutting efficiency.
[0022] This embodiment provides a cross-cutting machine with a lubrication function, such as Figure 1 As shown, it includes a cross-cutter body 1, a driving device 2, a cutter 3 and a lubricating assembly 4; the driving device 2 is fixedly installed on the cross-cutter body 1 and connected to the cutter 3, and the driving device 2 drives the cutter 3 to reciprocate up and down to cut the cardboard; the cross-cutter body 1 is provided with an oil delivery port 11, and an oil storage chamber 12 and a working chamber 13 are provided in the cross-cutter body 1, and the oil delivery port 11 is connected with the oil storage chamber 12, and the oil delivery port 11 is used to inject lubricating oil. When the lubricating oil in the oil storage chamber 12 is insufficient, the staff injects lubricating oil into the oil storage chamber 12 through the oil delivery port 11 to ensure that the lubricating oil in the oil storage chamber 12 is sufficient, and the oil storage chamber 12 is connected with the working chamber 13, and a mounting hole is provided between the oil storage chamber 12 and the working chamber 13 to realize the connection between the two;
[0023] The tool 3 is located below the working chamber 13, and the lubricating component 4 is located in the working chamber 13; the lubricating component 4 is in contact with the tool 3, and the tool 3 will enter the working chamber 13 when it moves upward to reset; when the tool 3 moves downward, it will drive the lubricating component 4 to secrete lubricating oil to lubricate the tool 3, and when the tool 3 moves upward, the lubricating component 4 will absorb oil for replenishment, and when the tool 3 moves upward, the top of the tool 3 will squeeze the lubricating component 4 to secrete lubricating oil, and when the tool 3 moves downward, the tool 3 is lubricated by the lubricating component 4, and the tool 3 is slidably installed with the working chamber 13.
[0024] like Figures 2 to 4 As shown, the one-way valve 41 is located between the oil storage chamber 12 and the working chamber 13, and the one-way valve 41 is installed in the installation hole between the oil storage chamber 12 and the working chamber 13. The oil storage bag 42 is located in the working chamber 13 and is connected to the one-way valve 41. One end of the one-way valve 41 is connected to the oil storage chamber 12, and the other end of the one-way valve 41 is fixedly connected to the oil storage bag 42. The oil storage bag 42 is a rubber air bag, and the rubber air bag has good elasticity. When the tool 3 is retracted, the top end of the tool 3 enters the working chamber 13 to squeeze the oil storage bag 42. The oil storage bag 42 is squeezed by external force to discharge the lubricating oil into the oil delivery pipe 44. When the cutter 3 is cutting the cardboard, the cutter 3 is separated from the working chamber 13 and is no longer squeezed by the oil storage bag 42. The oil storage bag 42 is no longer squeezed. As the lubricating oil inside the oil storage bag 42 is reduced, the pressure inside the oil storage bag 42 increases. The oil storage bag 42 restores the equilibrium pressure and absorbs oil from the oil storage chamber 12 to replenish itself. Under the action of the pressure difference, the oil storage bag 42 can quickly absorb oil from the oil storage chamber 12 to recover, so as to achieve rapid oil replenishment to meet the lubrication requirements.
[0025] The sponge pad 43 is located on both sides of the cutter 3 and connected to the crosscutting machine body 1. The sponge pad 43 fully absorbs and stores lubricating oil. Whenever the cutter 3 passes through the sponge pad 43, the lubricating oil absorbed in the sponge pad 43 will lubricate the cutter 3, thereby improving the cutting efficiency of the cutter 3 and reducing the wear of the cutter 3. The bottom end of the sponge pad 43 is a triangle 431; the sponge pad 43 is arranged obliquely, and the bottom end of the sponge pad 43 is a triangle 431, which can make the lubricating oil gradually converge in the process of flowing downward, increase the content of the lubricating oil at the bottom end, and improve the lubrication content of the cutter 3. The oblique arrangement of the sponge pad 43 can enhance the contact area with the tip of the cutter 3, thereby enhancing the lubrication effect on the tip of the cutter 3 and reducing the wear of the tip;
[0026] The oil storage bag 42 is connected to the sponge pad 43 through an oil delivery pipe 44. A one-way valve 41 is provided between the oil delivery pipe 44 and the oil storage bag 42. A one-way valve 41 is provided between the oil delivery pipe 44 and the oil storage bag 42, respectively, for limiting the flow direction of the lubricating oil, so that the lubricating oil can only flow in one direction along the direction of the oil storage cavity 12, the oil storage bag 42, the oil delivery pipe 44 and the sponge pad 43, and at the same time, avoid the backflow of the lubricating oil. There are four oil delivery pipes 44, and the oil delivery pipes 44 are symmetrically installed at both ends of the sponge pad 43 in pairs, which improves the oil delivery efficiency of the oil delivery pipe 44 to the sponge pad 43, so that the lubricating oil can quickly fill the sea The sponge pad 43, the oil pipe 44 is a transparent hose, the diameters at both ends of the oil pipe 44 are smaller than the diameter at the middle end, the oil pipe 44 is a transparent hose, it is easy to observe the content of the lubricating oil, when it is found that the lubricating oil in the oil pipe 44 is insufficient, the staff will add lubricating oil from the oil port 11 in time to meet the lubrication needs, the reduction in diameter at both ends of the oil pipe 44 can increase the pressure on the lubricating oil, and then increase the outflow speed of the lubricating oil, so that the lubricating oil quickly flows into the sponge pad 43, the diameter of the middle end of the lubricating oil is increased, and a small amount of lubricating oil can be stored to avoid the interruption of the lubricating oil due to untimely oil replenishment, thereby ensuring the continuity of lubrication.
[0027] The driving device 2 of the utility model is a starting push rod, and the pneumatic push rod is connected to the cutter 3. When the cylinder is pulled back, the cross-cutting knife cuts the material along the horizontal direction; when the cylinder is pushed, the cross-cutting knife returns to the starting position and prepares for the next cutting.
[0028] When the cross-cutting machine with lubrication function implemented in the present invention is in use, the staff injects lubricating oil into the oil storage chamber 12 through the oil delivery port 11, then seals the oil delivery port 11, starts the cross-cutting machine body 1 to work, and the driving device 2 drives the tool 3 to reciprocate to cut the cardboard. When the tool 3 is retracted and moves upward, the top of the tool 3 enters the working chamber 13 to squeeze the oil storage bag 42, and the oil storage bag 42 is pressurized to discharge the lubricating oil, and the lubricating oil enters the oil delivery pipe 44 through the one-way valve 41. The lubricating oil flows into the oil delivery pipe 44 and enters the sponge pad 43, and is absorbed and stored by the sponge pad 43; when the tool 3 moves downward for cutting, the top of the tool 3 is separated from the working chamber 13, and the oil storage bag 42 is no longer squeezed and absorbs oil from the oil storage chamber 12 to recover, and the tool 3 continues to move downward through the sponge pad 43, and the sponge pad 43 contacts the surface of the tool 3 to lubricate the surface of the tool 3, and a working cycle is completed.
