Description

Technical Field

[0001] The utility model relates to the technical field of textile raw material manufacturing, in particular to a fabric rubber coating machine. Background Art

[0002] Silicone coating or printing on fabrics has been increasingly widely used in clothing accessories. The traditional method of fabric coating is mainly to use a coating machine to coat straight lines, waves, grids, etc. on the fabric. The traditional method of fabric printing silicone is to use a rotary screen or screen printing method to print silicone patterns and text on the fabric.

[0003] Traditional ribbon gluing or silicone printing wastes silicone and is prone to completely covering the ribbon with glue due to intermittent glue supply from the brush. In addition, the elasticity and anti-slip effects are poor and cannot meet market demand. Therefore, a technical solution is needed to ensure complete wrapping of the fabric and save silicone. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a device that ensures complete wrapping of fabric and saves silica gel.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Taking the rubberized fabric as yarn as an example, a fabric rubberizing machine includes a rubberizing section and a baking section, wherein the rubberizing section is located in front of the baking section in the processing sequence; a traction device for pulling the processed yarn to move is provided at the front or rear of the rubberizing section and / or the baking section; the baking section is provided with a plurality of heating tubes facing the processed yarn; the rubberizing section is provided with a mold box for rubberizing the processed yarn, and the mold box is generally in the shape of a box with a closed bottom and closed sides; the mold box is provided with an inlet and a disengagement port matching the yarn, and liquid silicone is contained in the mold box, and the vertical height of the inlet is not higher than the liquid level of the liquid silicone in the mold box; the processed yarn is driven by the traction device and passes through the inlet, the liquid silicone in the mold box, the disengagement port, and the heating tube in sequence.

[0007] By adopting the above technical solution, the processed yarn first enters the mold box through the entrance, contacts the liquid silicone in the mold box, and is wrapped by the liquid silicone, then leaves the mold box from the exit with the liquid silicone, and enters the baking section while being surrounded by a layer of liquid silicone, and is baked by the heat emitted by the heating tube. The liquid silicone wrapped around the processed yarn is cured by heat, so that the surface of the processed yarn is completely wrapped with solid silicone, and the rubber coating can be made as thin as possible by reducing the distance between the exit and the yarn, saving silicone. In addition, the fabric rubber coating can better increase elasticity and has a good anti-slip effect, and can prevent dirt.

[0008] As an improved solution, the top of the mold box is open and opens upward; a glue injection device is also provided above the mold box, and the glue injection device injects liquid silicone downward into the glue injection box. Specifically, the vertical heights of the inlet and the outlet are not higher than the liquid level of the liquid silicone in the mold box.

[0009] By adopting the above technical solution, the top of the mold box is open, which is convenient for maintenance personnel to directly check the color, remaining amount and other production-related status of the liquid silicone in the mold box. When the injection equipment fails, the maintenance personnel can also manually add liquid silicone into the mold box from the top of the mold box to maintain the production tool from stopping due to the failure of the injection equipment.

[0010] As an improved solution, the top of the mold box is closed and provided with a glue injection hole that passes through the top of the mold box. A glue injection device is also provided above the mold box, and the glue injection device is connected to the glue injection hole through a glue injection pipe.

[0011] By adopting the above technical solution, the top of the mold box is closed, and the liquid silicone in the mold box is relatively isolated from the external production environment, which is beneficial to prevent the liquid silicone from being contaminated by external dust or other foreign matter.

[0012] As an improved solution, a liquid level sensor facing the liquid silicone is provided in the mold box. The liquid level sensor is connected to the injection device signal and can sense the liquid level height information of the liquid silicone in the mold box and send it to the injection device.

[0013] By adopting the above technical solution, the glue injection equipment can determine whether there is still enough liquid silicone in the mold box to wrap the processed yarn through the liquid level sensor. When the liquid level sensor senses that the liquid silicone level is too low, the glue injection equipment automatically starts to inject liquid silicone into the mold box.

[0014] As an improved solution, a weight sensor is provided at the bottom of the mold box, and the weight sensor is connected to the injection device signal and can sense the weight information of the liquid silicone in the mold box and send it to the injection device.

[0015] By adopting the above technical scheme, the glue injection equipment can determine whether there is still enough liquid silicone in the mold box to wrap the processed yarn through the weight sensor. If a large number of large bubbles are generated in the mold box, causing the liquid level sensor to sense that the height of the liquid surface (actually bubbles) meets the requirements, but in fact there is a lack of liquid silicone at the position in the mold box that matches the processed yarn, the weight sensor can enable the glue injection equipment to add liquid silicone in time to maintain normal production.

[0016] As an improved solution, the entry port and the escape port are detachably arranged on the side of the mold box, and the side of the mold box is provided with a mounting groove matching the entry port and the escape port.

[0017] By adopting the above technical solution, the mold box on the production line can be quickly adapted to yarns of different thicknesses and sizes by disassembling and assembling the exit ports and entry ports of different models and sizes, thereby reducing the time consumed in changing product models.

[0018] As an improved solution, the escape port is arranged at the top of the mold box, and a yarn steering member is provided inside the mold box below the escape port. The yarn steering member guides the processed yarn to enter the mold box from the entry port, changes the moving direction through the yarn steering member, and leaves the mold box vertically upward from the escape port; the baking section is located above the mold box, and a traction device is provided above the baking section. The processed yarn is moved vertically in the baking section under the action of the traction device and the escape port.

[0019] Specifically, the yarn turning member can be a roller with smooth sides, a guide pulley, a guide pipe and other structures. The present technical solution uses a roller with smooth sides as the yarn turning member. The yarn to be processed passes from the bottom of the roller around the side of the roller, turns 90 degrees and then moves vertically upward.

[0020] By adopting the above technical solution, the processed yarn moves vertically upward after being wrapped with liquid silicone in the mold box, and maintains this vertical upward posture until it is heated and solidified by the heating tube of the baking section. Since the processed yarn is always kept vertical before the liquid silicone is solidified, the liquid silicone wrapped around the processed yarn will only flow downward, and will not be concentrated or protruded to a certain point on the side of the processed yarn due to the influence of gravity, so that the thickness of the silicone wrapped around the processed yarn can be evenly distributed.

[0021] As an improved solution, a cooling section is provided above the baking section, and the cooling section is provided with a plurality of air outlets, and the air outlets are arranged facing the processed yarn.

[0022] Preferably, a dust removal filter material is provided in the air outlet.

[0023] By adopting the above technical solution, after the processed yarn passes through the baking stage, the silicone wrapped around it is shaped and solidified, and then cooled by the wind blown from the air outlet, and restored to room temperature as soon as possible, so that the silicone layer around the processed yarn is completely stable and can be directly rolled and wound for storage or directly woven.

[0024] As an improved solution, a shaping brush is provided between the rubber encapsulation section and the baking section. The shaping brush is arranged above the disengagement port and surrounds the processed yarn moving upward from the disengagement port.

[0025] By adopting the above technical solution, when the processed yarn is wrapped by liquid silicone and moves upward from the liquid silicone surface layer, if there are bubbles adhering to the periphery of the processed yarn, they will be intercepted and destroyed at the position of the shaping brush. The processed yarn that continues to move upward through the shaping brush and is ready to be heated by the baking section will not carry bubbles and cause quality problems.

[0026] As an improved solution, a visual sensor is provided between the rubber encapsulation section and the baking section, and the visual sensor is arranged above the disengagement port and faces the processed yarn.

[0027] By adopting the above technical solution, the diameter of the processed yarn after rubber coating will be measured by the visual sensor before it enters the baking section. When a fault occurs and causes the diameter of the processed yarn after rubber coating to be abnormal, the production line can be shut down and handled in time to reduce losses.

[0028] The fabric gluing machine of the present technical solution can also be applied to webbings, round ropes or other similar fabrics with long strips as the main morphological feature.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] The processed yarn first enters the mold box through the entrance, contacts the liquid silicone in the mold box, and is wrapped by the liquid silicone, then leaves the mold box from the exit with the liquid silicone, and enters the baking section while being surrounded by a layer of liquid silicone, and is baked by the heat emitted by the heating tube. The liquid silicone wrapped around the processed yarn is cured by heat, so that the surface of the processed yarn is completely wrapped with solid silicone, and then the yarn wrapped with silicone is woven into the ribbon through a ribbon weaving machine. This method can improve the appearance of the ribbon, make it applicable, and save silicone. In addition, the rubber coating of the rope can better increase the elasticity and have a good anti-slip effect, and when the ribbon is bent, since the adjacent yarns are not connected by silicone, the silicone on some yarns will not be pulled to produce cracks or fall off due to the change in the spacing between the yarns.

[0045] Implementation case 1:

[0046] As attached Figure 1 and 3 As shown, a fabric rubberizing machine comprises a rubberizing section 1 and a baking section 2, wherein the rubberizing section 1 is located in front of the baking section 2 in the processing sequence; a traction device 3 for pulling the processed yarn 5 to move is provided at the front or rear of the rubberizing section 1 and / or the baking section 2; the baking section 2 is provided with a plurality of heating tubes 4 facing the processed yarn 5; the rubberizing section 1 is provided with a mold box 6 for rubberizing the processed yarn 5, and the mold box 6 is generally in the shape of a box with a closed bottom and closed sides; the mold box 6 is provided with an inlet 7 and a disengagement port 8 matching the yarn, and liquid silicone 9 is contained in the mold box 6, and the vertical height of the inlet 7 is not higher than the liquid level of the liquid silicone 9 in the mold box 6; the processed yarn 5 is driven by the traction device 3 and passes through the inlet 7, the liquid silicone 9 in the mold box 6, the disengagement port 8, and the heating tube 4 in sequence.

[0047] The processed yarn 5 first enters the mold box 6 through the entrance 7, contacts the liquid silicone 9 in the mold box 6, and is wrapped by the liquid silicone 9, and then carries the liquid silicone 9 out of the mold box 6 from the exit 8, and enters the baking section 2 while being surrounded by a layer of liquid silicone 9, and is baked by the heat emitted by the heating tube 4. The liquid silicone 9 wrapped around the processed yarn 5 is cured by heat, so that the surface of the processed yarn 5 is completely wrapped with solid silicone, and then the yarn wrapped with silicone is woven into the ribbon through a ribbon weaving machine. This method can improve the appearance of the ribbon, make it applicable, and save silicone. In addition, the rubber coating of the rope can better increase the elasticity and have a good anti-slip effect, and when the ribbon is bent, since the adjacent yarns are not connected by silicone, the silicone on some yarns will not be pulled to produce cracks or fall off due to the change in the spacing between the yarns.

[0048] The mold box 6 is open at the top and opens upwards; a glue injection device 10 is also provided above the mold box 6, and the glue injection device 10 injects liquid silicone 9 downwards into the glue injection box. Specifically, the vertical heights of the inlet 7 and the outlet 8 are not higher than the liquid level of the liquid silicone 9 in the mold box 6.

[0049] The top of the mold box 6 is open, which is convenient for maintenance personnel to directly check the color, remaining amount and other production-related status of the liquid silicone 9 in the mold box 6. When the injection device 10 fails, the maintenance personnel can also manually add liquid silicone 9 into the mold box 6 from the top of the mold box 6 to ensure that the production tool does not stop running due to the failure of the injection device 10.

[0050] The mold box 6 is provided with a liquid level sensor 12 facing the liquid silicone 9 . The liquid level sensor 12 is connected to the injection device 10 by signal and can sense the liquid level height information of the liquid silicone 9 in the mold box 6 and send it to the injection device 10 .

[0051] The glue injection device 10 can determine whether there is still enough liquid silicone 9 in the mold box 6 to wrap the processed yarn 5 through the liquid level sensor 12. When the liquid level sensor 12 senses that the liquid level of the liquid silicone 9 is too low, the glue injection device 10 automatically starts to inject liquid silicone 9 into the mold box 6.

[0052] A weight sensor is provided at the bottom of the mold box 6 . The weight sensor is connected to the glue injection device 10 by signal, and can sense the weight information of the liquid silicone 9 in the mold box 6 and send it to the glue injection device 10 .

[0053] The glue injection device 10 can determine whether there is still enough liquid silicone 9 in the mold box 6 to wrap the processed yarn 5 through the weight sensor. If a large number of large bubbles are generated in the mold box 6, causing the liquid level sensor 12 to sense that the height of the liquid surface (actually bubbles) meets the requirements, but in fact there is a lack of liquid silicone 9 at the position matching the processed yarn 5 in the mold box 6, the weight sensor can enable the glue injection device 10 to add liquid silicone 9 in time to maintain normal production.

[0054] The entry port 7 and the escape port 8 are detachably arranged on the side of the mold box 6 , and the side of the mold box 6 is provided with a mounting groove matching the entry port 7 and the escape port 8 .

[0055] By disassembling and assembling the exit ports 8 and the entrance ports 7 of different sizes and types, the mold box 6 on the production line can be quickly adapted to the yarns of different thicknesses and sizes, thereby reducing the time consumed in changing the product model.

[0056] A cooling section is arranged above the baking section 2, and the cooling section is provided with a plurality of air outlets, and the air outlets are arranged facing the processed yarn 5. Dust removal filter material is arranged in the air outlets.

[0057] After the processed yarn 5 passes through the baking section 2, the silicone wrapped around it is shaped and solidified, and then cooled by the air blown from the air outlet, and restored to room temperature as soon as possible, so that the silicone layer around the processed yarn 5 is completely stable and can be directly rolled and wound for storage or directly woven. The dust removal filter material is installed at the air outlet to prevent dust from adhering to the surface of the wrapped silicone layer.

[0058] A visual sensor is provided between the rubber encapsulation section 1 and the baking section 2 . The visual sensor is arranged above the disengagement port 8 and faces the processed yarn 5 .

[0059] Before the processed yarn 5 enters the baking section 2, the diameter of the processed yarn 5 after being coated will be measured by the visual sensor. When a fault occurs and causes the diameter of the processed yarn 5 after being coated to be abnormal, the production line can be shut down and processed in time to reduce losses.

[0060] Implementation case 1:

[0061] As attached Figure 2 and 4 As shown in the figure, the difference from implementation case 1 is:

[0062] The escape port 8 is arranged at the top of the mold box 6, and a sand box steering member 13 is provided inside the mold box 6 below the escape port 8. The sand box steering member 13 guides the processed yarn 5 to enter the mold box 6 from the entry port 7, and changes the moving direction through the sand box steering member 13, and leaves the mold box 6 vertically upward from the escape port 8; the baking section 2 is located above the mold box 6, and a traction device 3 is provided above the baking section 2. The processed yarn 5 is acted upon by the traction device 3 and the escape port 8 in the baking section 2, and moves in a vertical direction.

[0063] The processed yarn 5 moves vertically upward after being wrapped with liquid silicone 9 by the mold box 6, and maintains this vertical upward posture until being heated and cured by the heating tube 4 of the baking section 2. Since the processed yarn 5 is always kept vertical before the liquid silicone 9 is cured, the liquid silicone 9 wrapped around the processed yarn 5 will only flow downward, and will not be concentrated or protruded to a certain point on the side of the processed yarn 5 due to the influence of gravity, so that the thickness of the silicone wrapped around the processed yarn 5 can be ensured to be evenly distributed.

[0064] The mold box 6 is closed at the top and is provided with a glue injection hole that passes through the top of the mold box 6 . A glue injection device 10 is also provided above the mold box 6 . The glue injection device 10 is connected to the glue injection hole through a glue injection pipe 11 .

[0065] The top of the mold box 6 is closed, and the liquid silicone 9 in the mold box 6 is relatively isolated from the external production environment, which is beneficial to prevent the liquid silicone 9 from being contaminated by external dust or other foreign matter.

[0066] A shaping brush 14 is provided between the rubber encapsulation section 1 and the baking section 2 . The shaping brush 14 is disposed above the disengagement port 8 and surrounds the processed yarn 5 moving upward from the disengagement port 8 .

[0067] When the processed yarn 5 is wrapped by the liquid silicone 9 and moves upward from the liquid surface layer of the liquid silicone 9, if there are bubbles adhering to the processed yarn 5, they will be intercepted and destroyed at the position of the shaping brush 14. The processed yarn 5 that continues to move upward through the shaping brush 14 and is ready to be heated by the baking section 2 will not carry bubbles and cause quality problems.

[0068] In summary, after reading the utility model document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the utility model without creative mental labor, and different application scenarios all fall within the scope of protection of the utility model.
