[0010] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0011] The technical solutions specifically implemented by the present utility model are as follows:

[0012] As Figure 1 shown, the present utility model provides a device for on-line measuring the width of a waterproof coiled material, including: a measuring platform, a conveying mechanism for conveying and guiding the waterproof coiled material 7 to intermittently pass on the top surface of the measuring platform, a coiled material width measuring device for measuring the width of the waterproof coiled material 7 on the measuring platform, a main control unit for judging whether the waterproof coiled material 7 is qualified according to the measurement data obtained by the coiled material width measuring device, and an alarm device triggered by the main control unit when the main control unit judges that the waterproof coiled material 7 is a defective product;

[0013] The coiled material width measuring device includes: a pair of clamping blocks 1 slid on the top surface of the measuring platform, separately arranged on the outer sides of both ends in the width direction of the waterproof coiled material 7 on the measuring platform and used for clamping both sides of the waterproof coiled material 7, cylinders 3 respectively connected to the outer ends of the pair of clamping blocks 1 through spring telescopic mechanisms 2 and used for driving the corresponding clamping blocks 1 to approach or move away from the side edges of the waterproof coiled material 7, and a clamping block spacing detection mechanism for detecting the spacing between the pair of clamping blocks 1; the clamping block spacing detection mechanism includes: a track 4 arranged directly above the measuring platform and horizontally arranged along the width direction of the waterproof coiled material 7 on the measuring platform, a traveling device 5 arranged on the track 4 and capable of moving from one clamping block 1 to the other clamping block 1 along the track 4, an induction unit 6 carried by the traveling device 5 and capable of being triggered twice successively by the pair of clamping blocks 1 during the movement of the traveling device 5, and a clamping block spacing calculation unit (the clamping block spacing calculation unit is not shown in the figure) for calculating the spacing between the pair of clamping blocks 1 according to the positions of the two successive triggers of the induction unit 6; the pair of clamping blocks 1 are symmetrically arranged; the cylinders 3 at the outer ends of the pair of clamping blocks 1 are symmetrically arranged; the pair of clamping blocks 1 are iron blocks; the induction unit 6 is a photoelectric switch.

[0014] The working principle of the device for on-line measuring the width of the waterproof coiled material of the present utility model includes:

[0015] The conveying mechanism conveys and guides the waterproof coiled material 7 to intermittently pass on the top surface of the measuring platform;

[0016] Each time the waterproof coiled material 7 pauses on the top surface of the measuring platform, the coiled material width measuring device measures the width of the waterproof coiled material 7 on the measuring platform and obtains the coiled material width measurement data; when the coiled material width measurement data exceeds the predetermined width data range, the main control unit judges that the waterproof coiled material 7 is a defective product and triggers the alarm device to give an alarm;

[0017] After each measurement by the coil width measuring device, the coil width measuring device disengages from the waterproof coil 7 on the measurement platform, and the conveying mechanism continues to convey the waterproof coil 7;

[0018] The coil width measuring device measures the width of the waterproof coil 7 on the measurement platform and obtains the coil width measurement data, including the following steps: The cylinders 3 at the outer ends of a pair of clamping blocks 1 respectively drive the corresponding clamping blocks 1 to approach the side edges of the waterproof coil 7 until the pair of clamping blocks 1 contact and press against the two side edges of the waterproof coil 7; then the traveling device 5 carries the sensing unit 6 to move along the track 4 from one clamping block 1 to the other clamping block 1. The sensing unit 6 is triggered twice successively by the pair of clamping blocks 1 during the movement of the traveling device 5. The clamping block spacing calculation unit calculates the spacing between the pair of clamping blocks 1 according to the positions of the two successive triggers of the sensing unit 6, and uses the spacing data of the pair of clamping blocks 1 as the coil width measurement data; the presence of the spring telescoping mechanism 2 can prevent the waterproof coil 7 from deforming due to excessive pressure exerted by the clamping blocks 1 on the waterproof coil 7 on the measurement platform (that is, prevent the waterproof coil 7 from deforming due to excessive pressure exerted by the coil width measuring device on the waterproof coil 7 on the measurement platform);

[0019] The coil width measuring device disengages from the waterproof coil 7 on the measurement platform, including the following steps: The cylinders 3 at the outer ends of a pair of clamping blocks 1 respectively drive the corresponding clamping blocks 1 to move away from the side edges of the waterproof coil 7 and reset; at this time, the pair of clamping blocks 1 are completely disengaged from the waterproof coil 7 on the measurement platform, and the pair of clamping blocks 1 do not hinder the continuous conveyance of the waterproof coil 7 (that is, the coil width measuring device does not hinder the continuous conveyance of the waterproof coil 7).

[0020] The present utility model uses a coil width measuring device with a spring telescoping mechanism 2 to perform on-line detection of the width of the waterproof coil 7; the presence of the spring telescoping mechanism 2 can prevent the waterproof coil 7 from deforming due to excessive pressure exerted by the clamping blocks 1 on the waterproof coil 7 on the measurement platform (that is, prevent the waterproof coil 7 from deforming due to excessive pressure exerted by the coil width measuring device on the waterproof coil 7 on the measurement platform); in this way, the accuracy of on-line detection of the width of the waterproof coil 7 can be improved.

[0021] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
