Description

Technical Field

[0001] The present invention relates to the technical field of fabric detection and feeding, and specifically to a feeding device for fabric coating visual detection. Background Art

[0002] In the process of fabric production, the coating process is an important link to improve the performance and appearance quality of fabrics. However, on the coated fabric, there are often some sundries remaining, such as lint, dust, fiber debris, etc. The existence of these sundries will have a serious impact on the subsequent fabric visual detection link, resulting in inaccurate detection results and even misjudging the quality of the fabric, thereby affecting the quality control and efficiency of the entire fabric production process.

[0003] When the traditional fabric feeding device transports the fabric to the visual detection equipment, it often lacks an effective cleaning function. Even if there is a simple cleaning device, most of them can only perform a single cleaning method, such as simple brush cleaning or simple suction dust removal, and the cleaning effect is limited. For example, when only using brush cleaning, it is difficult to completely remove the sundries tightly attached to the fabric coating; when only relying on suction dust removal, it is also difficult to effectively remove some larger particles of sundries or sundries with stronger adhesion. In addition, the traditional device cannot be flexibly adjusted according to the actual situation of the fabric (such as different materials, different pollution degrees, etc.) during the cleaning process, and it is difficult to meet the diverse production needs.

[0004] Therefore, there is an urgent need in the current market for a device that can effectively remove the sundries on the fabric coating, improve the accuracy of visual detection, and can adapt to different fabric materials and pollution situations to meet the strict requirements for quality and efficiency in modern fabric production.

It has multiple dust removal and cleaning functions, and solves the problem that when only using brush cleaning, it is difficult to completely remove the sundries tightly attached to the fabric coating; when only relying on suction dust removal, it is also difficult to effectively remove some larger particles of sundries or sundries with stronger adhesion.

[0021] (III) Advantageous Effects

[0022] Compared with the prior art, the present invention provides a feeding device for fabric coating visual inspection, which has the following advantageous effects:

[0023] 1. Through the setting of the power cleaning member in the cleaning mechanism of the present invention, sundries on the fabric coating can be scraped off by means of reciprocating scraping. Through the setting of the negative pressure cleaning member in the cleaning mechanism, not only can sundries on the fabric be sucked and removed by suction, but also the sundries scraped off by the power cleaning member by suction can be sucked and removed. It has multiple dust removal and cleaning functions, and can also perform operations on single or multiple cleaning members according to the actual cleaning situation, meeting the cleaning work of different fabrics and fabrics with different pollution conditions, strengthening the fabric cleaning effect, effectively improving the accuracy of subsequent visual inspection, and reducing the visual inspection error situation.

[0024] 2. Through the driving of the driving plate left and right by the electric cylinder of the present invention, not only can the sliding frame and the scraping frame be driven to move horizontally left and right to form a reciprocating sundry scraping operation, but also the angle of the scraping frame can be adjusted, so that when the electric cylinder pulls the driving plate, it can first control the scraping frame to move downward obliquely, making the scraping end at the bottom of the scraping frame in close contact with the fabric, and finally drive the scraping frame to pull to form a fabric sundry removal operation. On the contrary, when the electric cylinder pushes the driving plate, it can first control the scraping end of the scraping frame to move upward obliquely, losing contact with the fabric, and finally drive the scraping frame to push and reset. It has a good reciprocating scraping function, and solves the problem that when the scraping frame reciprocates left and right to scrape, when the scraping frame resets, it is easy to push the sundries away and cannot form a power cleaning operation.

[0025] 3. Through the pulling force of the tension spring group itself, the U-shaped tooth plate frame can be driven to contract, and the movement of the U-shaped tooth plate frame can drive the two rotating plates to rotate through meshing, and then drive the two adjusting rollers to perform circular motion, so as to straighten the fabric during the conveying process, and has an adaptive tension adjustment function, solving the problem that in the prior art, when the fabric conveying device conveys the fabric, it cannot adaptively adjust the tension of the fabric, resulting in wrinkles during the conveying process, which not only affects the sundry removal, but also affects the subsequent visual inspection effect.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1:

[0043] Refer to the attached Figures 1 - 10 A feeding device for fabric coating visual inspection includes a frame 1 and a visual inspection fixing frame 2 installed on the frame 1. A unwinding roller 3 and a winding roller 4 are respectively arranged inside the frame 1. The unwinding roller 3 is used to convey the fabric wound thereon to the winding roller 4. An installation frame 6 is fixedly connected to the frame 1, and a cleaning mechanism for cleaning the fabric is arranged on the installation frame 6;

[0044] Both the unwinding roller 3 and the winding roller 4 are in transmission connection with an external motor, so that the unwinding roller 3 and the winding roller 4 rotate. Through the rotation of the unwinding roller 3, the unwinding work of the fabric to be tested is formed. Through the rotation of the winding roller 4, the winding work of the tested fabric is carried out. Through the synchronous drive of the unwinding roller 3 and the winding roller 4, the feeding work of the fabric is formed;

[0045] Through the setting of the visual inspection fixing frame 2, it is convenient to install the visual inspection equipment in the prior art on the frame 1;

[0046] Through the setting of the cleaning mechanism, it is used to clean the debris such as lint and dust adhering to the fabric coating, improving the accuracy of subsequent visual inspection;

[0047] The cleaning mechanism includes a power cleaning member 7 and a negative pressure cleaning member 8 installed on the installation frame 6;

[0048] Through the setting of the power cleaning member 7 in the cleaning mechanism, the debris on the fabric coating can be scraped off by a reciprocating scraping method. Through the setting of the negative pressure cleaning member 8 in the cleaning mechanism, not only can the debris on the fabric be suctioned and removed by a suction method, but also the debris scraped off by the power cleaning member 7 can be suctioned and removed by a suction method;

[0049] It has multiple dust removal and cleaning functions, and can also operate single or multiple cleaning parts according to the actual cleaning situation, meeting the cleaning work of different fabrics and fabrics with different pollution conditions, enhancing the fabric cleaning effect, effectively improving the accuracy of subsequent visual inspection, and reducing the visual inspection error situation.

[0050] Refer to the appendix Figures 4 - 8 , the power cleaning part 7 includes a sliding frame 71, a scraping frame 72 arranged at the bottom of the sliding frame 71, and an electric cylinder 73 for driving the sliding frame 71 left and right. The scraping frame 72 is inclined, and the electric cylinder 73 is fixed to the top of the frame 1 through a bracket;

[0051] The electric cylinder 73 is connected to an external power supply and a control switch, and is set by using the connection method and coding method of the existing technology, and is used to drive the sliding frame 71 to move left and right. Through the left and right movement of the sliding frame 71, the scraping frame 72 can be driven to move left and right, forming a reciprocating power scraping work;

[0052] It should be noted here that the fabric conveying speed is lower than the telescopic driving frequency of the electric cylinder 73, so that the electric cylinder 73 can drive the scraping frame 72 to perform more than one power scraping work on the sundries on the fabric coating, forming multiple scraping works, further improving the power scraping effect;

[0053] The negative pressure cleaning part 8 includes a negative pressure frame 81 fixed to the mounting frame 6 through a bracket, and a telescopic suction pipe 82 is fixedly connected inside the negative pressure frame 81;

[0054] Through the setting of the negative pressure frame 81, it is used to cooperate with the suction pipe 82 to perform suction cleaning work on the sundries on the fabric coating or inside the scraping frame 72 through its own internal negative pressure state.

[0055] Refer to the appendix Figure 5 and Figure 6 , the power cleaning part 7 includes at least one guide rod 74 fixed to the mounting frame 6. A guide block 75 is slidably connected to the outer surface of the guide rod 74, and the guide block 75 is fixedly connected to the sliding frame 71;

[0056] Through the setting of the guide block 75 and the guide rod 74, it is used to improve the orderliness and smoothness of the reciprocating horizontal movement of the sliding frame 71, and thus improve the power scraping effect of the scraping frame 72.

[0057] Refer to the appendix Figures 5 - 8 , one end of the suction pipe 82 is communicated with the inside of the scraping frame 72 through a connection frame 83, and a one-way valve is installed on the suction pipe 82. A piston plate 84 is slidably connected inside the scraping frame 72, and a driving rod 85 is fixedly connected to one side of the piston plate 84;

[0058] By telescopically driving the driving rod 85, the piston plate 84 can be driven to reciprocate left and right. When the piston plate 84 reciprocates left and right, a negative pressure state can be formed inside the negative pressure frame 81. Furthermore, debris can be sucked through the suction pipe 82. Through the setting of the one-way valve, it is used to control the suction pipe 82 unidirectionally;

[0059] One end of the suction pipe 82 is connected to the inside of the scraping frame 72 through the connecting frame 83, so that the suction pipe 82 can orderly suck and process the scraped debris, improving the power cleaning performance of the scraping frame 72;

[0060] One end of the driving rod 85 is connected to the telescopic end of the electric cylinder 73. When the electric cylinder 73 drives the scraping frame 72 to perform power cleaning of debris, the negative pressure cleaning member 8 can be synchronously driven to form synchronous cleaning work, which has a good linkage function. Through the mutual cooperation between the two, not only the cleaning effect of debris on the fabric is improved, but also the energy conservation and environmental protection of the equipment are effectively improved;

[0061] Here, it should be noted that the suction end of the suction pipe 82 can be two. One end is connected to the inside of the scraping frame 72 through the connecting frame 83, and the other end is directly facing the fabric during the feeding process, forming a two-way suction and dust cleaning work.

[0062] Refer to the appendix Figure 5 、 Figure 6 and Figure 8 One end of the negative pressure frame 81 is open, and a cover plate 86 is detachably installed at the open end of the negative pressure frame 81. A filter screen 87 is provided on the cover plate 86, and a one-way valve piece 88 for unidirectionally controlling the filter screen 87 is elastically connected to the outer side of the cover plate 86;

[0063] Since one end of the negative pressure frame 81 is open and the cover plate 86 is detachably installed, it is convenient for the staff to lift it to remove the sucked debris inside the negative pressure frame 81;

[0064] Through the setting of the filter screen 87, when the piston plate 84 performs a reset movement, the gas inside the negative pressure frame 81 can be discharged through the filter screen 87, and the debris in the gas is separated by the filter screen 87;

[0065] Through the elastically installed one-way valve piece 88, when exhausting through the position of the filter screen 87, the one-way valve piece 88 is in an open state to form an orderly exhaust work. When the piston plate 84 expands, a negative pressure state can be formed in the negative pressure frame 81, and the one-way valve piece 88 can seal and block the filter screen 87, so that the negative pressure inside the negative pressure frame 81 is released through the suction pipe 82, enabling the suction pipe 82 to perform debris suction work, having good functions of debris suction, debris separation, and gas derivation.

[0066] Refer to the attached Figure 3 , a guide roller 5, an adsorption roller 10 and an orientation roller 11 are rotatably connected inside the frame 1, and an adjusting assembly 9 for adjusting the tension of the fabric during feeding is arranged at the bottom of the frame 1;

[0067] Through the arrangement of the guide roller 5, it is used to guide the fabric during the unwinding process. Through the arrangement of the adsorption roller 10, it is used to perform an adsorption treatment on the fabric after dynamic cleaning and negative pressure cleaning, aiming to further adsorb smaller lint and debris on the fabric coating. Through the arrangement of the adjusting assembly 9, it is used to adjust the tension of the fabric during transportation;

[0068] It should be noted here that the guide roller 5, the adsorption roller 10, the orientation roller 11 and the adjusting assembly 9 are in contact with the fabric in the manner shown in the attached Figure 3 and Figure 10 as shown.

[0069] Embodiment 2: The difference from Embodiment 1 is that;

[0070] Refer to the attached Figures 5 - 7 , a positioning frame 76 is hinged between the bottom of the sliding frame 71 and one side of the top of the scraping frame 72. Both sides of the inner wall of the sliding frame 71 are slidably connected in a vertical sliding manner with sliding blocks 77. A U-shaped rod 78 is fixedly connected between the two sliding blocks 77. Both ends of the bottom of the U-shaped rod 78 are hinged with inclined connecting rods 79. Both bottom ends of the two connecting rods 79 are hinged to one side of the top of the scraping frame 72. Two inclined transmission frames 710 are rotatably connected to the top of the U-shaped rod 78. One end between the two transmission frames 710 is rotatably connected with a driving plate 711. The driving end of the electric cylinder 73 is fixedly connected with the driving plate 711;

[0071] By driving the driving plate 711 left and right by the electric cylinder 73, not only can the sliding frame 71 and the scraping frame 72 be driven to move horizontally left and right to form a reciprocating debris scraping operation, but also the angle of the scraping frame 72 can be adjusted. When the electric cylinder 73 pulls the driving plate 711, it can first control the scraping frame 72 to move downward obliquely, so that the scraping end at the bottom of the scraping frame 72 is in close contact with the fabric, and finally drive the scraping frame 72 to be pulled to form a fabric debris removal operation. On the contrary, when the electric cylinder 73 pushes the driving plate 711, it can first control the scraping end of the scraping frame 72 to move upward obliquely to lose contact with the fabric, and finally drive the scraping frame 72 to be pushed back to its original position. It has a good reciprocating scraping function, and solves the problem that when the scraping frame 72 reciprocates left and right to scrape, when the scraping frame 72 is reset, it is easy to push the debris away and cannot form a dynamic cleaning operation;

[0072] The specific principle is as follows: when the driving plate 711 is pushed by the electric cylinder 73, the driving plate 711 can push the two inclined transmission frames 710, so that the two transmission frames 710 can move in a fan shape, and then drive the U-shaped rod 78 and the sliding block 77 to move upward. The upward movement of the U-shaped rod 78 can drive the scraping frame 72 to move upward in a fan shape with the positioning frame 76 as the axis through the two connecting rods 79, forming the contraction of the scraping frame 72, so that the scraping frame 72 will not contact the fabric when it is pushed to reset. When the sliding block 77 moves to the extreme position, it can drive the sliding frame 71 and the scraping frame 72 to be pushed and reset with the continuous push of the electric cylinder 73;

[0073] On the contrary, when the driving plate 711 is pulled by the electric cylinder 73, the driving plate 711 can pull the two inclined transmission frames 710, so that the two transmission frames 710 can move in a fan shape, and then drive the U-shaped rod 78 and the sliding block 77 to move downward. The downward movement of the U-shaped rod 78 can drive the scraping frame 72 to move downward in a fan shape with the positioning frame 76 as the axis through the two connecting rods 79, so that the scraping frame 72 can be unfolded and in close contact with the top of the fabric, so that when the scraping frame 72 is pulled, the scraping frame 72 can remove the debris on the fabric.

[0074] One end of the driving rod 85 is fixedly connected to the telescopic end of the electric cylinder 73 through the driving plate 711, and is used to drive the negative pressure removal member 8 synchronously when the sliding frame 71 is moved horizontally by the electric cylinder 73, so as to form a negative pressure suction operation. When the scraping frame 72 is being reset, the negative pressure frame 81 can be reset at the same time to wait for a new round of suction operation, which has a good coordination function.

[0075] The guide block 75 is slidably mounted on the outer surface of the guide rod 74 through an elastic clamping sleeve 712;

[0076] The guide block 75 is slidably connected to the guide rod 74 by an elastic clamping sleeve 712, so as to improve the resistance of the guide block 75 when it moves horizontally, thereby improving the electric cylinder 73 to reciprocate the sliding frame 71, and preferentially drive the scraping frame 72 to adjust the angle, thereby improving the orderliness of the power cleaning member 7 in cleaning the fabric debris;

[0077] And when the contact force between the scraping frame 72 and the top of the fabric is greater than the resistive friction force of the elastic clamping sleeve 712, the continuous operation of the electric cylinder 73 can form a high-intensity debris scraping work, which is convenient for when the fabric tension during transportation is low and the fabric is slightly loose as a whole. The contact force between the scraping frame 72 and the fabric must always be greater than the resistive friction force of the elastic clamping sleeve 712 to form the lateral movement of the scraping frame 72, thereby realizing the dynamic scraping work of fabrics with different tensions.

[0078] Embodiment 3: Different from Embodiment 1;

[0079] Referring to the attached Figure 9 and Figure 10 , the adjusting assembly 9 includes two support frames 91 fixed to the bottom of the frame 1. Between the two support frames 91, there are two adjusting rollers 92 with adjustable angles. The two adjusting rollers 92 are symmetrically arranged;

[0080] Through the arrangement of the two adjusting rollers 92, not only the orderliness of fabric conveying is improved, but also the tension of the fabric can be adjusted orderly, improving the smoothness and stability of fabric conveying;

[0081] The two adjusting rollers 92 are in contact with the fabric in the manner shown in the attached Figure 3 and Figure 10 .

[0082] Inside both of the two support frames 91, there are rotatably connected rotating plates 93. The two ends of the two adjusting rollers 92 are respectively rotatably connected between the two rotating plates 93; On the frame 1, there is a driving member for rotating and driving the two rotating plates 93;

[0083] Through the arrangement of the driving member, it is used to rotate and adjust the two rotating plates 93, and then the two adjusting rollers 92 can be adjusted to realize the adjustment of the fabric tension;

[0084] The driving member includes a tension spring group 95 arranged on the frame 1. One end of the tension spring group 95 is fixedly connected with a U-shaped tooth plate frame 96. On the outer sides of the two rotating plates 93, there are gear teeth 97. The U-shaped tooth plate frame 96 is meshed with the two rotating plates 93 through two groups of gear teeth 97. The U-shaped tooth plate frame 96 is slidably connected with the frame 1 through two guide rail frames 94;

[0085] Through the pulling force of the tension spring group 95 itself, the U-shaped tooth plate frame 96 can be driven to contract. The movement of the U-shaped tooth plate frame 96 can drive the two rotating plates 93 to rotate through meshing, and then drive the two adjusting rollers 92 to perform circular motion, so as to straighten the fabric during the conveying process, and it has the function of self-adaptive tension adjustment, solving the problem that in the prior art, when the fabric conveying device conveys the fabric, it cannot adaptively adjust the tension of the fabric, resulting in wrinkles during the conveying process, which not only affects the debris removal, but also affects the subsequent visual inspection effect;

[0086] On the frame 1, there is an adjusting member for adjusting the initial position of the tension spring group 95, such as a lead screw, for understanding the tension coefficient of the tension spring group 95 to meet the adjustment work of different strength tensions.

[0087] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
