Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment of the invention provides a main body structure diagram of a feeding mechanism and a cutting device, and is shown in fig. 3 and 4. Install the coiling dish 5 of having unsealed on the transmission shaft of second motor 6, silicone tube 3 neatly twines on coiling dish 5, passes stop device 4 with the free end of silicone tube 5, carries cutting device 1 via conveyor 2, and the free end of silicone tube 3 should reach appointed initial position, and initial position can appoint to cut the incision department at cutting device 1 to in calculate the number of times of cutting. The conveying device 2 comprises two groups of feeding rollers arranged in parallel, a single group of feeding rollers is divided into an upper roller and a lower roller, the silicone tube 3 is inserted between the upper roller and the lower roller, and a limiting groove can be arranged on the rollers to accommodate the silicone tube 3. The lower rollers of the two groups of feeding rollers are linked with the first motor 7 through the linkage belt, the rotating speeds of the two lower rollers are the same, and when the first motor 7 rotates, the feeding rollers can be driven to convey the silicone tube 3 in the limiting groove to the cutting device 1. The second motor 6 drives the coil tray 5 to rotate to release the silicone tube 3, so that the feeding roller can continuously convey the silicone tube 3 to the cutting device 1 for cutting.
The rotating speed of the first motor 7 directly influences the speed of the silicone tube 3 conveyed by the feeding roller, and the cutting consumption speed of the cutting device 1 needs to be met; the rotating speed of the second motor 6 directly affects the release speed of the silicone tube 3 on the coil tray 5, and when the release length of the silicone tube 3 in unit time is consistent with the consumption length of the cutting device, the length qualification rate of the cut finished product of the silicone tube 3 can be ensured, so that the feeding speed of the feeding mechanism and the material consumption speed of the cutting device need to be synchronized.
According to a first aspect of the present invention, as shown in fig. 1, there is provided a method for synchronizing a silicone tube feeding mechanism and a cutting device, comprising:
step S101: the rotating speed and the cutting time of the first motor are preset.
In the embodiment of the invention, the rotating speed of the first motor 7 directly affects the efficiency of the conveying device 2 for conveying the silicone tube 3, namely the length of the silicone tube 3 conveyed in unit time, and after the rotating speed of the first motor 7 is determined, the cutting frequency of the cutting device 1 is set according to the length of a required finished product, so that cut finished products with various lengths can be obtained only by adjusting the cutting frequency after the rotating speed of the first motor 7 is fixed. Therefore, after the rotation speed of the first motor 7 is preset, the conveying amount of the silicone tube 3 in unit time can be determined, the multi-stage speed change rule of the second motor 6 is convenient to set, and the release amount of the coiling tray 5 in unit time is controlled.
It can be understood that when the cutting device 1 cuts, a certain time is needed to complete the cutting, so that a cutting time is preset, and when the cutting device 1 starts cutting, the movement of the silicone tube 3 is suspended, so that the cutting device 1 can accurately cut a cut finished product with a length corresponding to the cutting frequency.
Step S102: the free end of the silicone tube is inserted into a designated initial position, a first motor is started, and the feeding roller is driven to convey the silicone tube to the cutting device.
In the embodiment of the invention, the coil tray 5 can be unsealed firstly and installed on the transmission shaft of the second motor 6, the silicone tube 3 at the free end of the part is released manually, and the free end of the silicone tube 3 passes through the limiting device 4. The interval of two sets of cylinders of transfer device 2 is adjusted to the rising for silicone tube 3 can insert into to appointed initial position, can also set up the spacing groove between the cylinder and be used for holding silicone tube 3. And finally, the distance between the two groups of rollers of the conveying device 2 is adjusted downwards, so that the feeding rollers can compress the silicone tube 3 in the limiting groove, and when the feeding rollers are driven by the first motor 7, the feeding rollers can continuously convey the silicone tube perpendicular to the knife edge of the cutting device 1 along the axis direction of the limiting groove, so that the tangent plane of the silicone tube 3 is parallel and level and is not inclined.
After the first motor 7 is started, the feeding roller can be driven to convey the silicone tube 3 to the cutting device 1 for cutting, and the conveying amount of the feeding roller to the cutting device 1 is a cutting length in a cutting period of the cutting device 1.
Step S103: when the cutting device is detected to enter the cutting state, the first motor is restarted after the first motor is paused for one cutting time until the cutting device enters the cutting state next time.
In the embodiment of the invention, the cutting device 1 can have two states, wherein one state is a cutting state, namely a working state for cutting the static silicone tube 3, and the duration of the state is a cutting time; the second state is a standby state, namely a working state of waiting for the feeding roller to convey a silicone tube with a cutting length into the knife edge, and the duration of the state is standby time. The sum of the standby time and the cutting time is a cutting period.
The cutting frequency of the cutting device 1 can be set according to the rotating speed of the first motor 7 and the required cutting length of the silica gel finished product, and the cutting device 1 periodically operates according to the cutting frequency.
The cutting device 1 periodically enters a cutting state according to cutting frequency, when the cutting device 1 is detected to enter the cutting state, the first motor 7 is paused, the feeding roller stops conveying, the silicone tube 3 at the knife edge is in a static state at the moment, the time for pausing the first motor 7 is a cutting time, the cutting device 1 waits for finishing cutting, then the first motor 7 is restarted, the feeding roller is driven to convey the silicone tube 3 into the knife edge until the next cutting state arrives, and the cutting device sequentially and periodically operates.
It can be understood that the cutting length of the silicone gel finished product is closely related to the rotating speed and cutting frequency of the first motor 7, so that:
when the rotating speed of the first motor 7 is kept unchanged, the cutting frequency is adjusted to be fast, the cutting length is shortened, and otherwise, the cutting length is increased. Can be adjusted according to actual conditions to obtain accurate values.
When the cutting frequency is kept unchanged, the rotating speed of the first motor 7 is adjusted to be fast, the cutting length is shortened, and otherwise, the cutting length is expressed. However, when the rotation speed of the first motor 7 is changed, the synchronization effect of the second motor 6 is broken, and it is necessary to correct the rotation speeds of the respective stages again, and therefore, it is preferable to change the clipping frequency and fix the rotation speed of the first motor 7.
Step S104: and calculating the residual radius value of the silicone tube on the coil stock, and gradually adjusting the rotating speed of the second motor according to a multi-stage speed change rule to drive the coil stock to have the same release length of the silicone tube in unit time.
In the embodiment of the present invention, the silicone tube 3 is regularly wound on the coil tray 5 in multiple layers, and when the rotation speed of the second motor 6 is fixed, the release speed of the silicone tube 3 when the silicone tube 3 is released to each layer is gradually reduced, so that the rotation speed of the second motor 6 needs to be gradually adjusted, so that the release amount of the silicone tube 3 in each layer per unit time is fixed, that is, the release amounts of the silicone tube 3 in the coil tray 5 per unit time are the same as the consumption of the silicone tube 3. The release speed of each level of silicone tubes 3 on the coil tray 5 is related to the distance between each level and the transmission shaft, which is called as the margin radius, and the rotating speed of the second motor 6 can be set differently according to the difference of the margin radius between each level, so as to balance the release speed of the silicone tubes 3 at each level and make the release speed consistent.
It will be appreciated that the initial state of the magazine 5 is such that the number of windings of the silicone tube 3 in the first level is different from the subsequent levels on the initial magazine 5, since a part of the silicone tube 3 is manually released with its free end inserted into the designated initial position. Since the distance between the material tray 5 and the designated initial position is not controllable, the number of winding turns of the first level is also an indeterminate value, and special treatment is required. While the number of subsequent winding turns in each level is fixed and the same.
The multi-stage speed change rule of the second motor 6 is formulated, and the method specifically comprises the following steps:
obtaining an initial allowance radius and the residual number of turns of the initial allowance radius;
wherein, the initial allowance radius is the first level allowance radius, the remaining number of turns is the remaining number of turns of winding, and the total length of the silicone tube 3 of the first level can be calculated according to the allowance radius and the number of turns of winding.
Setting a first pitch changing speed of the second motor 6 and the running time of the rotation at the first pitch changing speed according to the initial allowance radius and the residual number of turns of the initial allowance radius;
the release amount of the silicone tube 3 in a cutting period when the second motor 6 operates at the first pitch-variable speed is set as a cutting length, and the operation time is obtained by calculating the total length of the silicone tube 3 at the first level and the first pitch-variable speed.
Obtaining the residual radiuses of all levels on the coil tray 5, wherein the number of turns of the residual radiuses of all levels is the same;
except for the first level, the allowance radius of each level of the residual silicone tubes 3 on the coil tray 5 is obtained to form an orderly-arranged array, and the numerical value in the array is the allowance radius value of the corresponding level. The number of winding turns of the remaining silicone tubes 3 of each layer on the winding disc 5 is full, namely the number of winding turns is the same. The total length of the silicone tube 3 of each level can be obtained by calculating the allowance radius value and the winding number of each level.
Setting the variable pitch speed of each level of the second motor 6 and the running time of the second motor rotating at the variable pitch speed of each level according to the numerical value and the number of turns of the allowance radius of each level;
the pitch-variable speed of each level of the second motor 6 is set according to the remaining radius value and the number of turns of each remaining level, so that when the silicone tube 3 is released at any level, the release amount of the silicone tube 3 in one cutting period when the second motor 6 operates at the pitch-variable speed of the level is a cutting length, and the operation time is obtained by calculating the total length of the silicone tube 3 of the level and the pitch-variable speed of the level.
Acquiring a current allowance radius value, and adjusting the pitch changing speed of the second motor 6 and the running time of the rotation of the pitch changing speed in sequence according to the current allowance radius value;
