Description

Technical Field

[0001] This utility model belongs to the field of sound insulation cotton length measurement technology, and in particular relates to a sound insulation cotton length measurement device. Background Technology

[0002] The production steps of automotive sound insulation cotton are: breaking up the cotton material, humidifying it, weaving it, rolling it, and then rolling it up. It is then die-cut according to actual needs using cutting equipment. The rolling step is to facilitate the transfer to the next process. When the rolled material reaches a certain length, it needs to be cut.

[0003] Existing methods rely on manual observation of the roll diameter for cutting, or on setting marks on the winding frame to trigger cutting. Neither of these methods can guarantee the length of the sound insulation cotton each time it is wound up. The first method, manual observation, obviously cannot guarantee consistent length. The second method, which uses sensors to trigger cutting, changes the winding length at the same sensing position when the thickness of the sound insulation cotton changes, resulting in poor adaptability.

[0004] To address the aforementioned issues, this application proposes a sound insulation cotton length measuring device. Utility Model Content

[0005] The purpose of this invention is to provide a sound insulation cotton length measuring device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sound insulation cotton length measuring device, comprising a crossbar and a connecting block installed at the front end of the crossbar. The connecting block is provided with a hinged pressure plate, the upper end of which is hinged to the connecting block, and the lower end is fixed to an encoder. A roller is installed with the encoder. A tension spring is also provided between the pressure plate and the connecting block to elastically press the roller against the sound insulation cotton and make it roll. The pressure plate is provided with a hinged hanging rod, and a hanging plate is fixed at the front end of the crossbar. When the hanging rod is engaged in the hanging groove, the roller is lifted upward and positioned.

[0008] Furthermore, the connecting block includes a first clamping plate fixed to the crossbar and a second clamping plate fixed to the first clamping plate. The pressure plate is hinged to the connecting block via a rotatable adapter rod at its upper end, and the adapter rod is fixed to the second clamping plate.

[0009] Furthermore, an upper hanging ear is fixed on the second clamping plate, a lower hanging ear is fixed on the side of the pressure plate, and the two ends of the tension spring are respectively connected to the upper hanging ear and the lower hanging ear.

[0010] Furthermore, the hanging rod is hinged to the pressure plate via a rotating plate, with one end of the rotating plate hinged to the pressure plate and the other end fixed to the hanging rod, and the hanging rod is also fixedly provided with a handle along the axial direction.

[0011] Furthermore, the side of the hanging plate closest to the hanging groove is inclined, and the upper end of the hanging groove is open and has a chamfer.

[0012] Furthermore, a mounting base is fixed to the hanging plate, and the mounting base and the cover plate are fixed to the outside of the crossbar by bolts.

[0013] Furthermore, the crossbar has a hollow cable routing hole inside, and a fixing seat is fixed at one end of the crossbar.

[0014] This utility model has the following beneficial effects:

[0015] This utility model extends the encoder and roller from the side of the winding frame to the winding path of the sound insulation cotton through a crossbar. Then, under the action of the pressure plate and tension spring, the roller and the sound insulation cotton are pressed tightly. When the sound insulation cotton is wound up, the length can be calculated directly without considering the thickness of the sound insulation cotton, making it more adaptable.

[0016] This invention, by setting a rotating hanging rod on the pressure plate and cooperating with the hanging plate, can quickly position the roller after lifting it, which facilitates the entry of the sound insulation cotton before winding, and does not affect the elastic pressing after detachment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a sound insulation cotton length measuring device, including a crossbar 1 and a connecting block 2 installed at the front end of the crossbar 1. The connecting block 2 is provided with a hinged pressure plate 3. The upper end of the pressure plate 3 is hinged to the connecting block 2, and the lower end is fixed to the encoder 4. A roller 5 is installed with the encoder 4. A tension spring 6 is also provided between the pressure plate 3 and the connecting block 2 to make the roller 5 elastically fit against the sound insulation cotton and roll. The rolling surface of the roller 5 is covered with an anti-slip ring to prevent slippage from affecting the measurement standard. During the sound insulation cotton winding process, the roller 5 is driven to roll. The number of rotations of the roller 5 is converted into the calculation formula by the high-precision encoder 4: length = wheel circumference × number of rotations. This method can dynamically and continuously measure, and the data can be displayed in real time or transmitted to the control system, which greatly improves the production or cutting efficiency and avoids the error of manual measurement of thickness and roll diameter.

[0029] Furthermore, the pressure plate 3 is provided with a hinged hanging rod 8, and the front end of the crossbar 1 is fixed with a hanging plate 7. When the hanging rod 8 is engaged in the hanging groove 71, the roller 5 is lifted and positioned. In this state, a certain height is left between the roller 5 and the sound insulation cotton conveying table, which facilitates the picking and placing of the sound insulation cotton. The continuous compression of the tension spring 6 will not affect the ease of picking and placing, nor will it cause wrinkles in the sound insulation cotton.

[0030] Specifically, the connecting block 2 includes a first clamping plate 21 fixed to the crossbar 1 and a second clamping plate 22 fixed to the first clamping plate 21. Both the first clamping plate 21 and the second clamping plate 22 are provided with through holes, and a through groove is provided on one side of the through hole. The clamping and loosening are achieved by cooperating with the screw. The pressure plate 3 is hinged to the connecting block 2 through the adapter rod 31 rotatably connected at the upper end. The adapter rod 31 is fixed to the second clamping plate 22.

[0031] Furthermore, an upper hanging ear 221 is fixed on the second clamping plate 22, and a lower hanging ear 32 is fixed on the side of the pressure plate 3. The two ends of the tension spring 6 are connected to the upper hanging ear 221 and the lower hanging ear 32 respectively. Both hanging ears are fixed by welding. The hanging ears are "T"-shaped round rods that cooperate with the hanging rings at both ends of the tension spring 6 to prevent them from falling off.

[0032] Specifically, the hanging rod 8 is hinged to the pressure plate 3 via a rotating plate 81. One end of the rotating plate 81 is hinged to the pressure plate 3 and is biased towards the upper end, while the other end is fixed to the hanging rod 8. The hanging rod 8 is also fixed with a handle 82 along the axial direction.

[0033] Specifically, the side of the hanging plate 7 closest to the hanging groove 71 is inclined, and the upper end of the hanging groove 71 is open and has a chamfer. The inclined surface on the hanging plate 7 and the chamfer on the hanging groove 71 are to facilitate the entry of the hanging rod 8. At the same time, there are reinforcing ribs between the side of the hanging plate 7 and the mounting base 72 to ensure the support strength.

[0034] Specifically, a mounting base 72 is fixed on the hanging plate 7. The mounting base 72 and the cover plate 73 are fixed to the outside of the crossbar 1 by bolts. The mounting base 72 and the cover plate 73 have an arc-shaped surface that matches the connecting block 2 at one end close to each other. The mounting base 72 and the cover plate 73 are pressed together by bolts to stabilize the hanging plate 7.

[0035] Specifically, the crossbar 1 has a hollow cable routing hole inside, and a fixing seat 11 is fixed at one end of the crossbar 1. The cable routing hole forms a hidden channel for connecting wires between external control equipment and encoder 4, which facilitates cable routing. The fixing seat 11 has through holes for use with bolts to fix and install the crossbar 1.

[0036] Understandably, the encoder and rollers are extended to the sound insulation cotton winding path by the crossbar. Under the action of the pressure plate and tension spring, the rollers press the sound insulation cotton, realizing direct calculation of the winding length without being affected by the thickness. At the same time, the rotatable hanging rod on the pressure plate cooperates with the hanging plate to quickly lift and position the rollers, which facilitates the entry of the sound insulation cotton without affecting the pressing function.

[0037] A specific application of this embodiment is as follows: the crossbar 1 is fixed on the winding machine or the sound insulation cotton passing through the front end of the winding machine, the encoder 4 is fixed on the lower end of the pressure plate 3, the roller 5 is fixed on the rotating shaft of the encoder 4, the upper end of the pressure plate 3 is hinged to the connecting block 2 and the roller 5 is elastically pressed down to fit with the sound insulation cotton under the action of the tension spring 6.

[0038] Before winding, the handle 82 is used to lift the hanging rod 8 upward and lock it in the hanging groove 71. At this time, the pressure plate 3, encoder 4, and roller 5 are raised to facilitate the passage of the sound insulation cotton. The sound insulation cotton is connected to the winding roller, the hanging rod 8 is disengaged from the hanging groove 71, and the roller 5 is elastically attached to the sound insulation cotton by the tension spring 6. As the sound insulation cotton is wound, the roller 5 rolls on its upper end. The encoder 4 converts the number of rotations into a linear length signal to achieve the measurement purpose.
