Description

Technical Field

[0001] The invention belongs to the technical field of width detection, and in particular relates to an online width detection device for a shock-absorbing tape. Background Art

[0002] Shock-absorbing tape is a composite tape made of a laminated base material and a supporting material. During the production process of shock-absorbing tape, high-temperature raw materials (such as polyurethane, vinyl acetate, etc.) are mixed, molded, and then naturally cooled to shape. During the shaping process, the material will experience thermal expansion and contraction. After cooling, the width of the shock-absorbing tape needs to be measured to help identify the degree of width change caused by thermal expansion and contraction.

[0003] According to the measured width change, the production management personnel judge the dimensional stability of the tape after molding. If the width is found to be too small, it means that the fluidity is too high, and more reinforcing agent needs to be applied to the surface before cooling and shaping, and the amount of plasticizer added needs to be reduced. On the contrary, the reinforcing agent needs to be reduced and the amount of plasticizer added needs to be increased to keep the toughness of the finished product consistent. In the prior art, manual calculation and adjustment are required or computers and automatic control devices are relied on to achieve adjustment. The former is time-consuming and labor-intensive, and the latter increases the equipment cost. This phenomenon has become a problem that people in this field need to solve urgently.

DETAILED DESCRIPTION

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The present invention provides a technical solution: an online width detection device for a shock-absorbing tape, comprising four piston cylinders 2 arranged opposite to each other in pairs, a piston rod 21 is slidably installed inside the piston cylinder 2, one end of the piston rod 21 is connected to a contact plate 1, one end of the piston cylinder 2 is connected through a square shell 3, a scale indicator plate 31 is slidably installed inside the square shell 3, the square shell 3 is made of a transparent material and has a length scale code marked on the top, when it is necessary to measure the width of the shock-absorbing tape, it is transported by a conveyor belt, and the contact plate 1 is made to contact the two sides of the shock-absorbing tape, the translation of the contact plate 1 will drive the position of the piston rod 21 in the piston cylinder 2 to change, and the position of the scale indicator plate 31 will change through the pressure change, and the width of the shock-absorbing tape can be measured by observing the scale of the scale indicator plate 31 on the square shell 3, and this width detection method is carried out by conducting pressure through liquid, and compared with the conventional visual detection method, it is more stable through direct contact;

[0025] One end of the contact plate 1 is fixedly connected to an extension rod 11, and one end of the extension rod 11 is connected to an electromagnet 12. By energizing the electromagnet 12 and having a mutual attraction force, the electromagnet 12 will give the two contact plates 1 an initial force to move toward each other through the electromagnetic effect, so that the two contact plates 1 move toward each other. Since they will be blocked by the edge of the shock-absorbing tape, they will stop at a position in close contact with the shock-absorbing tape, thereby making the measurement result more accurate and reducing the gap between the contact plate 1 and the shock-absorbing tape. By adjusting the electromagnetic attraction of the electromagnet 12, the force of squeezing the two contact plates 1 against each other will not cause the shock-absorbing tape to deform.

[0026] One end of the square shell 3 is connected with a connecting pipe 4, and one end of the connecting pipe 4 is connected with an adjusting shell 6. A coating device 5 is arranged below the adjusting shell 6. A reinforcing agent supply end 61 and a plasticizer supply end 62 are correspondingly installed on the top of the adjusting shell 6. An intermediate rod 64 is fixedly installed at the inner center of the adjusting shell 6, and partition plates 63 are fixedly installed on both sides of the intermediate rod 64. Both sides of the partition plate 63 fit the inner wall of the adjusting shell 6. The outer wall of the intermediate rod 64 is correspondingly rotatably installed with a front end baffle 65 and a rear end baffle 66. Both the front end baffle 65 and the rear end baffle 66 are fan-shaped, and both are in sliding contact with the inner wall of the adjusting shell 6. When the pressure in the square shell 3 changes, it will transmit the pressure change to the adjusting shell 6 through the connecting pipe 4 through the liquid. The gap space between the front end baffle 65 and the rear end baffle 66 is two The amount of additive added, if the gap area between the two increases, the corresponding part of the additive will increase the input amount, otherwise it will reduce the input amount. The additive will enter the coating device 5 and flow to the top of the shock-absorbing tape, so that it can be cooled smoothly. Preferably, the coating device 5 should be located near the entry direction of the shock-absorbing tape, so that the surface of the shock-absorbing tape is coated with additives before it is formed, and the toughness of the finished product is adjusted. More reinforcing agent will make the shock-absorbing tape less deformed during the forming process, and more plasticizer will make the shock-absorbing tape more deformed during the forming process. When the relative angle between the front end baffle 65 and the rear end baffle 66 changes, the amount of one additive increases, and the corresponding amount of the other additive decreases in the same proportion. Compared with mechanical measurement of width, this adjustment method hydraulic measurement will reduce the width information through liquid pressure, which is convenient for adaptive adjustment of the amount of additives;

[0027] A fixed plate 67 is fixedly installed on the inner wall of the adjustment shell 6, and a folding capsule 68 is installed on one side of the fixed plate 67. A movable plate 681 is connected to one side of the folding capsule 68. The two movable plates 681 are fixedly connected to the bottom of the front baffle 65 and the rear baffle 66 respectively. Specifically, when the width of the shock-absorbing tape on the left and right sides of the coating device 5 becomes smaller, the pressure in the square shell 3 will be reduced in both directions, so that the two folding capsules 68 will become smaller, and the front baffle 65 and the rear baffle 66 will move in the same clockwise direction. At this time, the relative angle between the two does not change, so that the supply amount of the additive does not change. When the width of the shock-absorbing tape becomes very narrow during the shaping process, the folding capsule connected to the rear baffle 66 68 will be smaller than the folding capsule 68 connected to the front baffle 65, so that the opening of the side connected to the reinforcing agent becomes larger, so that the supply amount becomes more and the opening of the plasticizer becomes smaller, and the supply amount becomes less, so that the shock-absorbing tape has greater toughness and the deformation tends to decrease. When the deformation decreases, the folding capsule 68 connected to the rear baffle 66 will be closer in size to the folding capsule 68 connected to the front baffle 65, so that the supply amount of the reinforcing agent and the plasticizer reaches a dynamic balance according to the width change of the shock-absorbing tape. This adjustment method will only adjust the amount of additives when the width of the shock-absorbing tape changes relatively before and after the finalization, and the adjustment of the amount of additives will not be triggered if the width of the shock-absorbing tape itself changes at the beginning, so as to achieve the effect of adapting to shock-absorbing tapes of various widths;

[0028] A coating device 5 is provided at the bottom of the adjustment housing 6. Two connecting pipes 4 located on one side of the coating device 5 are connected to each other through the folding capsule 68 below the front baffle 65 after merging with each other. Two connecting pipes 4 located on the other side of the coating device 5 are connected to each other through the folding capsule 68 below the rear baffle 66 after merging with each other. The coating device 5 is used to apply additives to the upper part of the shock-absorbing tape, so that the toughness of the tape changes during the cooling and shaping process, thereby changing the degree of thermal expansion and contraction, and making the width of the tape tend to be consistent.

[0029] A circular groove 641 is correspondingly provided at the bottom end of the middle rod 64, and a sealing sheet 642 is slidably installed inside the circular groove 641. The outer wall of the sealing sheet 642 contacts the inner wall of the circular groove 641. Side channels 69 are correspondingly connected on both sides of the middle rod 64. One end of the side channel 69 is connected to the circular groove 641, and the other end of the side channel 69 is connected to the folding capsule 68. A part of the liquid passing through the folding capsule 68 will enter the circular groove 641. By adjusting the position of the sealing sheet 642, the circular groove 641 can accommodate more or less liquid, so that the size change degree of the folding capsule 68 can be adjusted. When the internal space of the circular groove 641 disappears, the liquid will all enter the folding capsule 68, and the folding capsule 68 will be larger, so that the positions of the front baffle 65 and the rear baffle 66 can be manually adjusted in advance;

[0030] The inner wall of the circular groove 641 near the opening is provided with an internal thread, and the inner wall of the circular groove 641 is movably connected with a circular thread block 644 through a thread, and a knob 645 is fixedly installed at the bottom end of the circular thread block 644, and a spring 643 is installed on the top of the circular thread block 644, and the top of the spring 643 is connected to the bottom of the sealing sheet 642. When it is necessary to manually adjust the adjustment range of the front baffle 65 and the rear baffle 66 to the width of the shock-absorbing tape, the two knobs 645 are synchronously turned by hand to make the circular thread block 644 rotate and adjust up and down. The position is adjusted, so that the tension degree of the spring 643 is different. When the same liquid pressure enters the circular groove 641, the sealing sheet 642 will be pressed to a different position, and the limit capacity of the liquid in the circular groove 641 is adjusted. If the capacity is reduced, more liquid will be squeezed into the folding capsule 68 to increase it, and the angle of the moving plate 681 to move will become larger, so that the opening change between the two under the same pressure change is more obvious. If the capacity is increased, less liquid will flow into the folding capsule 68, so that the opening change is not obvious.

[0031] The coating device 5 includes a liquid outlet pipe 81 rotatably mounted on the top thereof, the liquid outlet pipe 81 is movably connected to the bottom of the adjustment housing 6, a driven wheel 85 is mounted on the outer wall of the liquid outlet pipe 81, a brush plate 84 is mounted on the bottom of the liquid outlet pipe 81, a motor 82 is mounted on the top of the coating device 5, and a driving wheel 83 is connected to the output end of the motor 82, and the driving wheel 83 is meshed with the driven wheel 85. When the mixed liquid of the reinforcing agent and the plasticizer flowing out of the adjustment housing 6 flows out, they are merged together through the liquid outlet pipe 81 and flow to the bottom at the same time. The top of the shock-absorbing tape at the end is coated with a reinforcing agent and a plasticizer before it is cooled and shaped, so that the toughness area of ​​the finished product is consistent. During coating, the motor 82 is started, and its output shaft drives the driving wheel 83 to rotate, and drives the driven wheel 85 to rotate through the meshing action, so that the liquid outlet pipe 81 rotates, and drives the brush plate 84 below to rotate. Since the mixed liquid will flow to the top of the unshaped shock-absorbing tape, the rotation of the brush plate 84 will drive the brush installed thereon to evenly coat the liquid, so that the additives above the shock-absorbing tape are fully mixed.

[0032] Figure 5 There are four working states. The first and second are the situations where the width of the shock-absorbing tape reaches an ideal change degree before and after cooling and shaping. Regardless of the initial width of the shock-absorbing tape, the two front baffles 65 and the rear baffles 66 will rotate in the same direction and the same angle. The third is the situation where the width of the shock-absorbing tape becomes very narrow and the opening of the reinforcing agent becomes larger. The fourth is when the width change does not meet the requirements and the opening of the plasticizer becomes larger.
