Description

Technical Field

[0001] The present invention relates to the technical field of the production of composite fabrics for sofas, and specifically to a production device for composite fabrics for sofas. Background Art

[0002] In the field of multi-layer material lamination for composite fabrics for sofas, the roller pressing lamination device has become one of the key devices widely used in the industry due to its significant advantage of enabling continuous production. The roller pressing device tightly laminates multiple layers of materials such as the surface layer (decoration layer), the middle layer (buffer / support layer), and the bottom layer (base fabric) through the rotation and extrusion of the upper and lower rollers, effectively meeting the requirements of large-scale production of sofa fabrics.

[0003] However, in the existing roller pressing devices, the method of adjusting the distance between the upper and lower rollers by using hydraulic rods generally has many technical drawbacks that are difficult to overcome. During long-term use, the seals of the hydraulic rods will gradually wear due to frequent reciprocating movements, and at the same time, the hydraulic oil is easily contaminated by impurities. The wear of the seals and the contamination of the hydraulic oil will directly cause pressure instability and leakage problems, which in turn lead to deviations in the roller spacing; the above deviations will cause the lamination pressure to be large and small during production, resulting in serious quality defects such as air bubbles and delamination in local areas of the fabric;

[0004] In addition, the influence of environmental temperature fluctuations on the roller pressing device adjusted by hydraulic rods is significant. When the environmental temperature is high, the viscosity of the hydraulic oil decreases, the fluidity increases, and leakage is likely to occur, and the response speed of the hydraulic system becomes slow, resulting in slow adjustment of the roller spacing; in a low-temperature environment, the viscosity of the hydraulic oil increases, the fluidity becomes poor, and it is difficult for the hydraulic rods to start, and even the situation of not being able to work properly occurs; in the cold northern regions of China in winter, some enterprises have the situation that the hydraulic rods cannot effectively adjust the roller spacing due to low temperature, and the equipment shutdown and maintenance time increases significantly, seriously affecting the production progress;

[0005] Moreover, after the adjustment of the roller spacing in the existing technology, there is a lack of an effective real-time feedback monitoring mechanism. During the actual production process, due to factors such as equipment vibration and material tension changes, even the initially adjusted roller spacing changes; but because there is no device for randomly checking the distance between the upper and lower rollers in real time, the operator cannot timely detect the change in the spacing, resulting in quality problems in a large amount of fabrics produced subsequently. The above quality hidden dangers not only cause waste of materials, but also lead to customer complaints due to unqualified product quality, damaging the reputation of the enterprise;

[0006] In summary, the existing roller pressing lamination device that uses hydraulic rods to adjust the roller spacing and lacks feedback monitoring can no longer meet the high-quality and high-efficiency production requirements of composite fabrics for sofas, and there is an urgent need for a new lamination device that can solve the above problems.

[0007] Therefore, the present invention proposes a production device for composite fabrics for sofas to solve the above problems. Summary of the Invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose a production device for composite fabrics for sofas to solve the problems existing in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: A production device for composite fabrics for sofas, comprising: a connecting member and a roller, the roller is located in the middle of the symmetrically arranged connecting members, and further comprising: a first component and a second component, the second component is arranged inside the first component;

[0010] The first component is used for adjusting the distance between the rollers;

[0011] The second component is used to assist the components in the first component to be stable.

[0012] Preferably, the first component includes a main body frame fixedly connected to the connecting member, a transverse groove is opened on the main body frame, and a longitudinal groove is penetrated through the main body frame.

[0013] Preferably, an auxiliary member A is slidably connected in the transverse groove, plugging rods are symmetrically and fixedly connected to the auxiliary member A, springs are symmetrically and fixedly connected to the auxiliary member A, and a stabilizing groove is opened inside the main body frame.

[0014] Preferably, an adjusting member B is slidably connected inside the main body frame, and scale lines are opened on the adjusting member B.

[0015] Preferably, an adjusting strip is slidably connected in the longitudinal groove, a rotating wheel is rotatably connected inside the adjusting strip, and a friction ring is fixedly connected to the rotating wheel.

[0016] Preferably, the second component includes fixing grooves A symmetrically opened on the main body frame, clamping bars are slidably connected in the fixing grooves A, fixing pieces are fixedly connected to the outer ends of the clamping bars, and the main body frame and the adjusting member B are fixedly connected through the fixing pieces.

[0017] Preferably, a through-strip groove is opened on the adjusting member B, and fixing grooves B are equidistantly and symmetrically opened on the adjusting member B.

[0018] Preferably, a driving member is fixedly connected to the main body frame, a sleeve is fixedly connected to the driving member, and cards are symmetrically and fixedly connected to the sleeve.

[0019] Compared with the prior art, the present invention provides a production device for composite fabrics for sofas, having the following beneficial effects:

[0020] 1. The present invention has the following advantages through the design of the overall device:

[0021] Significantly improve the use stability: In the traditional hydraulic rod adjustment method, due to the wear of seals and the pollution of hydraulic oil, the pressure is unstable and the deviation of the roller spacing occurs, resulting in a relatively high defective rate of the fabric. This device realizes the precise adjustment and stable maintenance of the upper and lower roller spacing through a mechanical transmission structure. Moreover, all mechanical components have no risk of hydraulic oil leakage and will not cause pressure fluctuations due to seal failure. The adjustment accuracy error of the roller spacing is controlled within the process requirements, and the pressure fluctuation range is small during the production process, effectively avoiding defects such as bubbles and delamination of the fabric caused by uneven pressure. The qualified rate of the finished product is effectively improved, ensuring the stability and continuity of the production process;

[0022] Enhance environmental adaptability and versatility, and effectively extend the equipment life: After getting rid of the dependence of the hydraulic system on environmental temperature and humidity, this device can operate stably in a relatively wide temperature environment. The hydraulic system is greatly affected by temperature. High temperature causes the viscosity of hydraulic oil to decrease and leak, and low temperature makes it difficult to start, accelerating the aging of components and shortening the service life of the equipment. The all-mechanical component design of this device is less affected by environmental temperature. The mechanical transmission structure is enhanced in wear resistance and fatigue resistance through special heat treatment processes. The service life of this device is longer than that of traditional hydraulic adjustment devices, reducing the equipment renewal cost of enterprises and increasing the return on investment in fixed assets;

[0023] Greatly reduce the maintenance cost: The maintenance of the hydraulic system requires regular replacement of seals and cleaning and filtering of hydraulic oil, with a relatively high annual maintenance cost, and each maintenance is time-consuming and laborious. This device adopts a modular mechanical design, and the core transmission components are all made of wear-resistant alloy steel, reducing component wear and the intrusion of external impurities. The daily maintenance only requires regular inspection of the tightness and lubrication status of the mechanical connection parts, without complex hydraulic system maintenance operations, reducing the equipment downtime for maintenance and improving the equipment utilization rate.

[0024] 2. The present invention can bring the following advantages through the addition of scale lines:

[0025] Build a real-time feedback monitoring system: Due to the lack of a real-time monitoring mechanism in the prior art, the roller spacing is prone to deviation under the influence of factors such as equipment vibration and material tension change, but it is difficult to detect in time, resulting in the production of a large number of defective products. The scale lines of this device can cooperate with auxiliary observation devices, such as magnifying glasses and laser locators, to quickly spot-check the roller spacing during the production process. When the scale line shows that the spacing deviates from the set value, the operator can detect it and correct it through the mechanical adjustment mechanism, forming a closed-loop control of "setting - monitoring - feedback - adjustment", effectively avoiding quality losses caused by out-of-control spacing;

[0026] Eliminate hydraulic system interference and ensure monitoring reliability: In the hydraulic rod adjustment method, pressure fluctuations caused by seal wear and hydraulic oil contamination will indirectly interfere with the monitoring of the roller spacing, rendering the traditional scale markings worthless; this device uses a fully mechanical structure and adds scale lines to avoid the unstable factors of the hydraulic system; mechanical components are not affected by hydraulic oil leakage and pressure fluctuations during operation, and the spacing values marked by the scale lines are true and reliable, and the mechanical structure itself has high stability. With the above combination, even under long-term high-frequency adjustments, the long-term effectiveness of the monitoring data can be ensured, and the monitoring reliability is effectively improved compared with traditional hydraulic adjustment devices;

[0027] Lower the operation threshold and maintenance costs: The visual design of the scale lines greatly simplifies the operation process. New employees can start operating only after training on scale readings and simple mechanical adjustments. Compared with the complex pressure parameter debugging of the hydraulic system, the operation training cycle is effectively shortened; at the same time, as a pure mechanical marking, the scale lines do not require additional maintenance, completely eliminating the maintenance costs such as replacing hydraulic system seals and cleaning hydraulic oil, and significantly improving the production economy of the enterprise.

[0028] 3. The present invention enables the adjusting member B to have a replaceable usage mode by means of the design of the through slot, which has the following advantages:

[0029] Greatly improve the adjustment efficiency: In the traditional adjustment method, a single structure is difficult to meet the requirements of rapid large-range adjustment and fine micro-adjustment, resulting in a long single-adjustment spacing time when replacing fabrics of different thicknesses. This device is equipped with replaceable inclined plane modules with different slopes, that is, the adjusting member B with a large slope inclined plane is used for coarse adjustment, and the adjusting member B with a small slope inclined plane is used for fine adjustment. Operators can quickly replace the appropriate module according to actual needs; significantly reduce the equipment downtime for adjustment and improve the continuous operation ability of the production line;

[0030] Precisely match diverse production needs: The production of sofa composite fabrics covers various material and thickness combinations. The traditional fixed-structure adjustment method cannot balance accuracy and efficiency under different working conditions; this replaceable inclined plane design achieves functional complementarity through slope differentiation and meets the production needs of each fabric;

[0031] Reduce operation complexity and labor costs: The traditional adjustment structure requires operators to repeatedly try based on experience to balance the adjustment speed and accuracy, with high requirements for technical proficiency; this device uses a standardized replaceable inclined plane module adjusting member B to convert the complex adjustment logic into a simple operation of "replacing parts as needed"; new employees can quickly complete the replacement of the inclined plane module and the spacing adjustment according to the production work order instructions only after a very short training. Compared with the traditional method, the operation training cycle is shortened. At the same time, the clear module function division, such as the red-marked coarse adjustment module and the blue-marked fine adjustment module, further reduces the risk of human operation errors, significantly reducing labor costs and quality losses.

[0049] The first component 3 is used for adjusting the distance between the rollers 2; the first component 3 includes a main body frame 301 fixedly connected to the connecting piece 1. A transverse groove 302 is opened on the main body frame 301, and a longitudinal groove 303 is opened through the main body frame 301. An auxiliary part A304 is slidably connected in the transverse groove 302. Plug rods 305 are symmetrically and fixedly connected to the auxiliary part A304.

An adjusting strip 310 is slidably connected in the longitudinal groove 303. A rotating wheel 311 is rotatably connected inside the adjusting strip 310. A friction ring 312 is fixedly connected to the rotating wheel 311.

[0050] Among them:

[0051] The connecting piece 1 is fixedly connected to the laminator through a fixing piece; the roller 2 with temperature is used for conveying and pressing the composite fabric.

[0052] The first component 3 is used for adjusting the distance between the rollers 2.

[0053] The plug rod 305 is used in cooperation with the stable groove 307.

[0054] The auxiliary part A304 and the adjusting part B308 are slidably adapted to the transverse groove 302 in the transverse groove 302.

[0055] The slope of the inclined surface where the auxiliary part A304 contacts the rotating wheel 311 is smaller than the slope of the inclined surface where the adjusting part B308 contacts the rotating wheel 311.

[0056] The adjusting part B308 with different slopes can be replaced according to the specific adjustment situation, so as to perform the rough adjustment and fine adjustment actions of the distance during the corresponding use process.

[0057] The scale line 309 is used to indirectly feedback the adjusted moving distance of the roller 2.

[0058] Further embodiments: Please refer to Figure 2 , Figures 5 to 8 as shown in:

[0059] The second component 4 is used to assist the components in the first component 3 to be stable. The second component 4 includes fixing grooves A401 symmetrically opened on the main body frame 301. A clamping bar 402 is slidably connected in the fixing groove A401. A fixing piece 403 is fixedly connected to the outer end of the clamping bar 402. The main body frame 301 and the adjusting member B308 are fixedly connected through the fixing piece 403. A through-strip groove 404 is opened on the adjusting member B308. Fixing grooves B405 are symmetrically and equidistantly opened on the adjusting member B308. A driving member 406 is fixedly connected to the main body frame 301. A sleeve 407 is fixedly connected to the driving member 406. Cards 408 are symmetrically fixedly connected to the sleeve 407.

[0060] Among them:

[0061] The second component 4 is used to assist the components in the first component 3 to be stable.

[0062] A recessed groove adapted to the clamping bar 402 is provided in the fixing groove A401.

[0063] The sliding of the clamping bar 402 in the fixing groove A401 and the cooperation between the sleeve 407 on the driving member 406 and the through-strip groove 404 can provide a stable guiding function for the movement of the cards 408.

[0064] The fixing groove B405 is used in cooperation with the cards 408.

[0065] The working principle of all the contents in the above embodiments is as follows:

[0066] In the initial state:

[0067] The spring 306 is not compressed, and the cards 408 are in a parallel state with the inner wall of the main body frame 301.

[0068] The following is the working process of the first component 3:

[0069] When in use, first select the adjustment member B308 according to the specific work requirements, and then slide the adjustment member B308 into the transverse groove 302. As the adjustment member B308 slides, the inclined surface end of the adjustment member B308 in contact with the friction ring 312 on the rotating wheel 311 will push the rotating wheel 311 through the friction ring 312, and the rotating wheel 311 will be pushed with the assistance of the auxiliary member A304. Further, since the pushed rotating wheel 311 is connected to the adjustment bar 310, the rotating wheel 311 will move with the adjustment bar 310 in the longitudinal groove 303 at this time, and the moving adjustment bar 310 will adjust the position of the roller 2 fixed thereon. In this process, the plug-in rod 305 and the stabilizing groove 307 provide a stable movement guide for the movement of the auxiliary member A304, and the spring 306 is compressed.

[0070] Furthermore, as the adjustment member B308 slides in the transverse groove 302, the height of the corresponding position of the adjustment bar 310 will be indirectly adjusted; during the adjustment process, the operator can refer to the alignment state between the outer frame edge of the main frame 301 and the scale line 309 on the adjustment member B308 to determine whether the adjustment degree at this time meets the process requirements;

[0071] Please refer to the above working process Figures 1 to 4 , Figure 6 , Figure 8 .

[0072] The following is the working process of the second component 4:

[0073] Furthermore, when the adjusting member B308 is inserted into the transverse groove 302 to indirectly adjust the position of the roller 2, the card strip 402 that is fixedly connected to the adjusting member B308 through the fixing plate 403 and slidably engaged in the fixing groove A401 will follow its movement; and further, when the position of the adjusting member B308 is adjusted, the driving member 406 can be started, so that the driving member 406 rotates with the sleeve 407, and during the rotation of the sleeve 407, the sleeve 407 will carry the card 408, so that the card 408 is engaged in the fixing groove B405; at this time, under the action of the fixing groove A401, the card strip 402, and the sleeve 407 and the fixing groove B405, the position of the adjusting member B308 will be fixed, and the distance between the rollers 2 is adjusted; the next step can be carried out to convey and press the composite fabric through the roller 2;

[0074] Please refer to the above working process Figure 2 , Figures 5 to 8 .

[0075] Furthermore, through the design of the overall device, the use stability can be significantly improved. In the traditional hydraulic rod adjustment method, the pressure is unstable and the deviation of the distance between the rollers 2 is caused by the wear of the seals and the pollution of the hydraulic oil, resulting in a high defective rate of the fabric. Through the mechanical transmission structure of this device, the accurate adjustment and stable maintenance of the distance between the upper and lower rollers 2 are realized. Moreover, all mechanical components have no risk of hydraulic oil leakage and will not cause pressure fluctuations due to seal failure, so that the adjustment accuracy error of the distance between the rollers 2 is controlled within the process requirements, and the pressure fluctuation range during the production process is reduced, effectively avoiding defects such as bubbles and delamination of the fabric caused by uneven pressure, and effectively improving the qualified rate of the finished product, ensuring the stability and continuity of the production process;

[0076] At the same time, the environmental adaptability and versatility are enhanced, and the service life of the equipment is effectively extended. That is, after getting rid of the dependence of the hydraulic system on the environmental temperature and humidity, this device can operate stably in a relatively wide temperature environment. The hydraulic system is greatly affected by temperature. High temperature causes the viscosity of the hydraulic oil to decrease and leak, and low temperature makes it difficult to start, accelerating the aging of components and shortening the service life of the equipment. The all-mechanical component design of this device is less affected by the environmental temperature. The mechanical transmission structure is enhanced in wear resistance and fatigue resistance through special heat treatment processes. The service life of this device is longer than that of the traditional hydraulic adjustment device, reducing the equipment renewal cost of the enterprise and increasing the return on investment in fixed assets;

[0077] In addition, the maintenance of the hydraulic system requires regular replacement of seals and cleaning and filtering of the hydraulic oil, with a relatively high average annual maintenance cost, and each maintenance is time-consuming and laborious. This device adopts a modular mechanical design, and the core transmission components are all made of wear-resistant alloy steel, reducing component wear and the intrusion of external impurities. The daily maintenance only requires regular inspection of the tightness and lubrication status of the mechanical connection parts, without complex hydraulic system maintenance operations, reducing the equipment downtime for maintenance and improving the equipment utilization rate;

[0078] Furthermore, through the addition of the scale line 309, a real-time feedback monitoring system can be effectively constructed. That is, due to the lack of a real-time monitoring mechanism in the existing technology, the distance between the rollers 2 is prone to deviation under the influence of factors such as equipment vibration and material tension change, but it is difficult to detect in time, resulting in the production of a large number of defective products. The scale line 309 of this device can cooperate with auxiliary observation devices, such as magnifying glasses and laser locators, to quickly spot-check the distance between the rollers 2 during the production process. When the scale line 309 shows that the distance deviates from the set value, the operator can notice and correct it through the mechanical adjustment mechanism, forming a closed-loop control of "setting - monitoring - feedback - adjustment", effectively avoiding quality losses caused by out-of-control distance;

[0079] Moreover, the visual design of the scale line 309 greatly simplifies the operation process. New employees can start operating after only receiving training on scale reading and simple mechanical adjustment. Compared with the complex pressure parameter debugging of the hydraulic system, the operation training cycle is effectively shortened. At the same time, as a pure mechanical mark, the scale line 309 requires no additional maintenance, completely eliminating the maintenance costs such as the replacement of hydraulic system seals and the cleaning of hydraulic oil, and significantly improving the production economy of the enterprise.

[0080] Furthermore, by means of the design of the through slot 404, the adjusting part B308 has a replaceable usage method, which can greatly improve the adjustment efficiency. That is, in the traditional adjustment method, a single structure is difficult to meet the requirements of rapid large-range adjustment and fine micro-adjustment, resulting in a long single-adjustment spacing time when replacing fabrics of different thicknesses. This device is equipped with replaceable inclined plane modules with different slopes. The adjusting part B308 with a large slope is used for coarse adjustment, and the adjusting part B308 with a small slope is used for fine adjustment. The operator can quickly replace the adapted module according to actual needs, significantly reducing the equipment downtime for adjustment and improving the continuous operation ability of the production line.

[0081] At the same time, in the traditional adjustment structure, the operator needs to repeatedly try based on experience to balance the adjustment speed and accuracy, which requires a high level of technical proficiency. This device uses the standardized replaceable inclined plane module adjusting part B308 to transform the complex adjustment logic into a simple operation of "replacing parts as needed". New employees can quickly complete the replacement of the inclined plane module and the adjustment of the spacing according to the production work order instructions after only a very short training time. Compared with the traditional method, the operation training cycle is shortened. At the same time, the clear division of module functions, such as the red-marked coarse adjustment module and the blue-marked fine adjustment module, further reduces the risk of human operation errors, significantly reducing labor costs and quality losses.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
