Specific embodiments

[0019] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: Refer to Figure 1 - Figure 4 , an underwear processing positioning and clamping device for clothing production disclosed by the present invention, includes a base 1; It further includes: A positioning and clamping assembly 2, the positioning and clamping assembly 2 is arranged on the top side of the base 1, the positioning and clamping assembly 2 includes a lower die 21, two elastic plates 22, a rectangular plate 23 and a clamping plate 24, the lower die 21 is arranged on the base 1, and two elastic plates 22 are arranged on the top side of the lower die 21, the rectangular plate 23 is arranged on one side of the elastic plate 22, and one end of the rectangular plate 23 is inserted between the two elastic plates 22 and fixedly connected to the two elastic plates 22, a clamping opening 25 is formed on the other side of the elastic plate 22, and a driving mechanism 27 is arranged at a position corresponding to the elastic plate 22 in the lower die 21 to drive the two elastic plates 22 to reciprocate on the lower die 21; The clamping plate 24 is arranged above the die groove of the lower die 21, and the clamping plate 24 is located on the other side of the two elastic plates 22, and the clamping plate 24 is used for clamping the underwear; An adjusting assembly 3, the adjusting assembly 3 is arranged above the clamping plate 24, and the adjusting assembly 3 is used for adjusting the vertical position of the clamping plate 24; A driving assembly 4, the driving assembly 4 is arranged outside the other end of the rectangular plate 23, and the driving assembly 4 provides a driving force for the adjusting assembly 3.

[0021] In this embodiment, please refer to Figure 2 shown, the base 1 is a production line station, and an installation groove is arranged thereon for placing a storage box. Please refer to Figure 3 and 6As shown, the lower mold 21 is plate-shaped, and the top side is inwardly recessed to form two mold grooves for placing the fixed coaster. The lower mold 21 can be fixed to the base 1 by bolts. The operator places the fixed coaster in the mold groove, and makes the end of the fixed coaster away from the elastic plate 22 slightly tilt upward to complete the loading operation of the fixed coaster. The tilting amplitude when the fixed coaster is placed can have a large deviation, which facilitates the loading operation of the fixed coaster. Then the driving mechanism 27 starts to push the two elastic plates 22 forward until the clamping opening 25 is removed from the lower mold 21, and then the operator inserts one side of the cloth into the two clamping openings 25, and the cloth is clamped and positioned through the elastic reset deformation of the plate wall of the elastic plate 22, so that the corresponding side of the cloth is connected to the two elastic plates 22, and then the driving mechanism 27 drives the two elastic plates 22 to move in the opposite direction and reset. Since the two elastic plates 22 pull the cloth from the corresponding side of the cloth, the cloth is flatly unfolded and placed on the lower mold 21, and the corresponding position of the cloth is just located on the top side of the mold groove of the lower mold 21. The adjustment and positioning of the cloth is completed, and the corresponding position of the cloth and the mold groove will not produce position deviation, which will affect the processing effect of the device; It should be noted that when the device is in use, a control host can be installed on the base 1 for automatic control of the device to enhance the degree of automation of the device; Please refer to Figure 4 As shown, during the movement of the elastic plate 22, due to the fixation of the elastic plate 22 and the rectangular plate 23, the moving elastic plate 22 can drive the rectangular plate 23 to slide synchronously on the top side of the lower mold 21, please refer to Figure 3 As shown, the movable rectangular plate 23 passes through the gap between the clamping plate 24 and the lower mold 21, and in the process of the rectangular plate 23 gradually covering the mold groove of the lower mold 21, due to the mutual interference between the bottom side of the rectangular plate 23 and the fixed coaster, the raised part of the fixed coaster can be pressed into the mold groove along the inclined side of the fixed coaster. As the fixed coaster rotates in the mold groove, the fixed coaster is gradually adjusted to a straight state and placed in the mold groove. The adjustment and positioning of the fixed coaster is completed, and the placement of the fixed coaster in the mold groove always maintains a specific angle, and no angle deviation will occur, which affects the processing effect of the device. During the resetting and movement of the rectangular plate 23, a corresponding high-pressure chamber can be formed in the driving component 4. Subsequently, after the positioning of the cloth and the fixed coaster is completed, part of the gas in the high-pressure chamber inside the driving component 4 flows into the adjusting component 3, and the adjusting component 3 starts to push the clamping plate 24 downward, so that the clamping plate 24 is pressed on the cloth, and cooperates with the lower mold 21 to complete the pressing and clamping operation of the cloth. The device has a high degree of automation, which can greatly reduce the labor intensity of the operator when using the device.

[0022] In a further preferred embodiment of the present invention, Figure 3As shown, the bottom sides of the two elastic plates 22 and the bottom side of the rectangular plate 23 are in contact with the top side of the lower mold 21, and the two elastic plates 22 are oppositely arranged on both sides of the two mold grooves of the lower mold 21; In this embodiment, please refer to Figure 3 As shown, the rectangular plate 23 contacts the top side of the lower mold 21, so that the rectangular plate 23 slides along the top side of the lower mold 21, so that when the rectangular plate 23 passes through between the clamping plate 24 and the lower mold 21, it can completely push the fixed cup into the mold groove, and the two elastic plates 22 are relatively arranged on both sides of the two mold grooves, so that the length of the rectangular plate 23 can completely cover the two mold grooves.

[0023] In a further preferred embodiment of the present invention, Figure 4 Right now Figure 5 As shown, the opening of the clamp 25 close to the clamp plate 24 is flared, and a soft pad 26 is fixedly mounted on the inner wall of the clamp 25; In this embodiment, please refer to Figure 4 and Figure 5 As shown, the setting of the soft pad 26 can enhance the roughness of the inner wall of the clamp 25, and the flared setting of the clamp 25 can facilitate the operator to insert the side edge of the cloth into the clamp 25. When the operator inserts the side edge of the cloth into the two clamps 25, as the cloth and the soft pad 26 conflict with each other, the soft pad 26 shrinks and deforms to leave space for the side edge of the cloth to be inserted into the clamp 25. Subsequently, after the side edge of the cloth is inserted into the clamp 25, the pad wall of the soft pad 26 expands and deforms, cooperating with the reset deformation of the wall of the elastic plate 22, which can enhance the resistance between the cloth and the soft pad 26, thereby greatly enhancing the friction between the side edge of the cloth and the elastic plate 22, and finally enhancing the connection effect between the side edge of the cloth and the two elastic plates 22.

[0024] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Figure 7 As shown, the driving mechanism 27 includes two motors 271, which are relatively fixedly mounted on the side wall of the lower mold 21, and a slide groove 272 is provided at the position of the top side of the lower mold 21 corresponding to the elastic plate 22, and a threaded rod 273 is rotatably mounted in the slide groove 272, and the driving end of the motor 271 is inserted into the lower mold 21 and fixedly connected to the corresponding end of the corresponding threaded rod 273, and a slider 274 is provided in the slide groove 272, and the top end of the slider 274 is fixedly connected to the corresponding elastic plate 22, and the threaded rod 273 threads through the corresponding slider 274; In this embodiment, the motor 271 can be a DC motor 271 or a three-phase asynchronous motor 271. Figure 3 , Figure 6 and Figure 7As shown, the motor 271 starts to drive the threaded rod 273 to rotate forward, thereby pushing the slider 274 to slide in the chute 272 away from the motor 271. The motor 271 drives the threaded rod 273 to rotate in the reverse direction, thereby pushing the slider 274 to slide in the chute 272 towards the motor 271. And during the process of the slider 274 reciprocatingly sliding in the chute 272, the elastic plate 22 can be driven to reciprocatingly move on the top side of the lower die 21 synchronously.

[0025] In a further preferred embodiment of the present invention, as Figure 7 shown, the cross-sectional shape of the slider 274 and the cross-sectional shape of the chute 272 are both set in a T shape, and the outer wall of the slider 274 is in contact with the inner wall of the corresponding chute 272; In this embodiment, please refer to Figure 7 shown. During the process of the slider 274 reciprocatingly sliding in the chute 272, due to the mutual contact between the slider 274 and the inner wall of the chute 272, the slider 274 moves in a linear trajectory in the chute 272, thereby restricting the reciprocating movement trajectory of the elastic plate 22, so that the elastic plate 22 synchronously moves in a linear trajectory reciprocatingly.

[0026] In a further preferred embodiment of the present invention, as Figure 3 and Figure 8 shown, the adjusting assembly 3 includes two brackets 31. The two brackets 31 are relatively arranged on both sides of the clamping plate 24, and the bottom end of each bracket 31 is fixedly connected to the lower die 21. A piston cylinder 32 is fixedly installed at the top end of the bracket 31. A piston rod 33 is slidably installed in the piston cylinder 32, and the bottom end of the piston rod 33 passes through the plate wall of the corresponding bracket 31 and is fixedly connected to the corresponding end of the clamping plate 24; In this embodiment, please refer to Figure 3 and Figure 8 shown. The gas flowing out of the driving assembly 4 is directly injected into the piston cylinder 32. The gas flowing into the piston cylinder 32 pushes the piston rod 33 downward, and drives the clamping plate 24 to move towards the lower die 21 until the clamping plate 24 presses on the fabric, and cooperates with the lower die 21 to complete the clamping operation of the fabric on the outer peripheral side of the die groove. Subsequently, the gas continuously flowing into the piston cylinder 32 increases the air pressure in the piston cylinder 32, so as to apply a corresponding downward pressure to the clamping plate 24 and enhance the clamping strength of the fabric.

[0027] In a further preferred embodiment of the present invention, as Figure 8 shown, a limiting ring 34 is fixedly sleeved on the outer peripheral side of the piston rod 33, a spring 35 is wound around the outer peripheral side of the piston rod 33, and both ends of the spring 35 are fixedly connected to the corresponding limiting ring 34 and the corresponding bracket 31 respectively; In this embodiment, please refer to Figure 8As shown, after the fixed cup of the underwear is processed, due to the pushing of the spring 35 on the limiting ring 34, the piston rod 33 extending from the piston cylinder 32 automatically retracts into the piston cylinder 32, without the need to set up an additional driving source or driving structure, and the structure of the device is simple and the production cost is low.

[0028] In a further preferred embodiment of the present invention, as Figure 3 , Figure 4 and Figure 9 shown, the driving component 4 includes a gas storage shell 41, the gas storage shell 41 is slidably sleeved on the other end of the rectangular plate 23, and the gas storage shell 41 is fixedly connected to the lower die 21 by bolts. A sealing ring 42 is fixedly installed in the wall of the other end of the rectangular plate 23, and the outer ring wall of the sealing ring 42 is in contact with the inner wall of the gas storage shell 41. Two flow guide pipes 43 are oppositely arranged on the top side of the gas storage shell 41, and one end of each flow guide pipe 43 is communicated and installed with the air inlet end of the corresponding piston cylinder 32; In this embodiment, please refer to Figure 4 and Figure 9 shown, during the reset movement of the rectangular plate 23, the other end of the rectangular plate 23 directly inserts into the gas storage shell 41. Due to the sealing of the gap between the rectangular plate 23 and the inner wall of the gas storage shell 41 by the sealing ring 42, the rectangular plate 23 gradually inserted into the gas storage shell 41 gradually compresses the gas in the gas storage shell 41, so that a high-pressure chamber is formed in the gas storage shell 41, without the need to set up an additional air injection structure or an additional power source, reducing the production cost of the device.

[0029] In a further preferred embodiment of the present invention, as Figure 3 , Figure 8 and Figure 9 shown, two electric control three-way valves 44 are fixedly installed on the top side of the gas storage shell 41 relatively, and the air inlet end of each electric control three-way valve 44 extends between the inner wall of the rectangular plate 23 and the gas storage shell 41. The top exhaust port of the electric control three-way valve 44 is communicated and installed with the other end of the corresponding flow guide pipe 43. A heating and shaping component 5 is arranged on one side of the gas storage shell 41 away from the lower die 21; In this embodiment, please refer to Figure 8 and Figure 9 shown, when the rectangular plate 23 slides out of the gas storage shell 41, the electric control three-way valve 44 controls the connection between the inside of the gas storage shell 41 and the outside, so as to prevent the formation of a negative pressure chamber in the gas storage shell 41 during the process of the rectangular plate 23 moving out of the gas storage shell 41 and affecting the operation of the device; After the adjustment and positioning of the fabric are completed, the electric control three-way valve 44 controls the connection between the inside of the flow guide pipe 43 and the inside of the gas storage shell 41, so that the redundant gas in the gas storage shell 41 is introduced into the piston cylinder 32 through the flow guide pipe 43; After the processing operation of the device is completed, the electronically controlled three-way valve 44 controls the communication between the diversion pipe 43 and the outside. At this time, the excess gas in the piston cylinder 32 flows out through the diversion pipe 43 and the electronically controlled three-way valve 44 to relieve the high-pressure state in the piston cylinder 32. At this time, the spring 35 can directly push the piston rod 33 extending from the piston cylinder 32 directly into the piston cylinder 32.

[0030] In a further preferred embodiment of the present invention, as Figure 2 and Figure 10 shown, the heat setting assembly 5 includes an upper mold 52. The upper mold 52 is arranged above the clamping plate 24. A support frame 51 is provided on one side of the air storage shell 41 away from the lower mold 21. The bottom end of the support frame 51 is fixedly connected to the base 1. An electronically controlled hydraulic telescopic rod 53 is fixedly installed on the top side of the support frame 51. The driving rod of the electronically controlled hydraulic telescopic rod 53 passes through the plate wall of the support frame 51 and is fixedly connected to the upper mold 52; In this embodiment, the upper mold 52 is the top mold of an existing fixed cup processing device and can complete the heating treatment of part of the fabric and the fixed cup pad. Please refer to Figure 2 , Figure 3 and Figure 10 shown. After the clamping operation of the fabric is completed, the electronically controlled hydraulic telescopic rod 53 is started to push the upper mold 52 towards the mold groove. Please refer to Figure 8 shown. The middle part of the clamping plate 24 is hollowed out to form an inner hole so that the bottom end of the upper mold 52 can directly pass through the clamping plate 24 and move the bottom end of the upper mold 52 towards the mold groove through the inner hole of the clamping plate 24 until the bottom end of the upper mold 52 is inserted into the mold groove to complete the clamping operation of the fabric and the fixed cup pad. Subsequently, the heat setting treatment of part of the fabric and the fixed cup pad is completed according to the processing method of the existing fixed cup processing device mold.

[0031] Working principle: When the improved underwear processing device is used, first pass the fixed cup pad through the inner hole of the clamping plate 24 and place the fixed cup pad in the mold groove so that one end of the fixed cup pad away from the elastic plate 22 tilts slightly upwards to complete the feeding operation of the fixed cup pad. Then the motor 271 is started to drive the threaded rod 273 to rotate forward. At this time, due to the mutual contact between the slider 274 and the inner wall of the chute 272, the rotating threaded rod 273 cannot drive the slider 274 to rotate synchronously. The forward rotating threaded rod 273 pushes the slider 274 to move slowly, that is, slide in the direction away from the motor 271; During the forward movement of the slider 274, the elastic plate 22 can be synchronously driven to move synchronously, and since the elastic plate 22 is fixed to the rectangular plate 23, the rectangular plate 23 can be synchronously driven to slide against the top side of the lower mold 21, so that the rectangular plate 23 passes between the clamping plate 24 and the lower mold 21, and during the sliding process of the bottom side edge of the rectangular plate 23 located at the top side of the mold groove of the lower mold 21, the bottom side edge of the rectangular plate 23 and the two inclined side edges of the raised portion of the fixed coaster are in conflict with each other, and then the raised portion of the fixed coaster is gradually pressed into the mold groove along the two inclined side edges of the raised portion of the fixed coaster, so that the fixed coaster is located in the mold groove and rotates, and the angle of the fixed coaster is adjusted until the fixed coaster completely slides into the mold groove, and at this time, the open end of the fixed coaster is stably kept in a straight state and placed in the mold groove; During the process of the rectangular plate 23 moving forward, the rectangular plate 23 can be gradually slid out of the air storage shell 41, and the electric-controlled three-way valve 44 is started, so that the interior of the air storage shell 41 is connected with the outside, and during the process of the rectangular plate 23 sliding out of the air storage shell 41, due to the expansion of the space between the rectangular plate 23 and the inner wall of the air storage shell 41, the outside air is sucked into the air storage shell 41 through the electric-controlled three-way valve 44, until the rectangular plate 23 slides out of the air storage shell 41, and the electric-controlled three-way valve 44 is closed; When the clamp 25 is removed from the lower mold 21, that is, when the clamp 25 moves to the front side of the lower mold 21, the slider 274 and the inner wall of the slide groove 272 conflict with each other, the motor 271 stops running, and the elastic plate 22 stops moving. Then the operator pulls the two corners of the cloth to straighten one side of the cloth, and then moves the cloth to insert the straightened side of the cloth into the two clamps 25 through the expansion of the clamp 25. Due to the mutual conflict between the cloth and the soft pad 26, the soft pad 26 shrinks and deforms to leave space for the straightened side of the cloth to be inserted into the clamp 25. After the straightened side of the cloth is inserted into the clamp 25, the pad wall of the soft pad 26 expands and deforms to cooperate with the elastic reset deformation of the wall of the elastic plate 22, which can generate a large conflict force between the cloth and the soft pad 26, thereby making A large friction force is generated between the stretched side of the cloth and the soft pad 26, and the stretched side of the cloth is stably connected to the two elastic plates 22 through the friction force. Then the motor 271 drives the threaded rod 273 to rotate in the opposite direction, driving the elastic plate 22 to move and reset, thereby pulling the stretched side of the cloth to move in the direction of the motor 271. At this time, due to the mutual conflict between the cloth and the side of the lower mold 21, the cloth can be pulled to the top side of the lower mold 21 by the elastic plate 22, and the cloth can be pulled flat and straightened in the process of the elastic plate 22 pulling the cloth to the top side of the lower mold 21, so that the cloth is spread more evenly on the top side of the lower mold 21. After the elastic plate 22 is reset, the corresponding position of the cloth is just located above the fixed coaster, and the positioning operation of the cloth is completed. During the process of resetting the elastic plate 22, the rectangular plate 23 can be synchronously driven to be gradually inserted into the gas storage shell 41. Since the sealing ring 42 blocks the gap between the rectangular plate 23 and the inner wall of the gas storage shell 41, the rectangular plate 23 gradually inserted into the gas storage shell 41 can synchronously complete the compression process of the gas in the gas storage shell 41, so that a high-pressure chamber with a corresponding strength is formed in the gas storage shell 41. After the positioning of the fabric and the fixed cup pad is completed, the electrically controlled three-way valve 44 is started, so that the interior of the guide tube 43 is connected with the interior of the gas storage shell 41, and part of the gas in the gas storage shell 41 gradually flows into the piston cylinder 32 through the guide tube 43, so that a high-pressure chamber with gradually increasing pressure is formed in the piston cylinder 32, until the pressure in the piston cylinder 32 is equal to the pressure in the gas storage shell 41. When the thrust of the high-pressure chamber in the piston cylinder 32 on the piston rod 33 is greater than the thrust of the spring 35 on the limit ring 34, part of the piston rod 33 is gradually pushed out of the piston cylinder 32, and the limit ring 34 is synchronously driven to compress the spring 35 until the clamping plate 24 is pressed on the fabric. At this time, the clamping plate 24 cooperates with the lower mold 21 to complete the pressing and clamping of part of the fabric on the outer peripheral side of the mold groove, and as the high-pressure chamber in the piston cylinder 32 further rises, the pressing and clamping strength of the fabric can be enhanced until the pressing strength of the pressing plate on the fabric reaches a threshold value; After the clamping operation of the fabric is completed, the electrically controlled hydraulic telescopic rod 53 is started to push the upper mold 52 toward the mold groove. After the bottom end of the upper mold 52 passes through the inner hole of the clamping plate 24, due to the mutual interference between the bottom end of the upper mold 52 and the fabric, the corresponding position of the fabric undergoes a corresponding state of tensile deformation, and the bottom end of the upper mold 52 is gradually inserted into the mold groove until the bottom end of the upper mold 52 cooperates with the inner wall of the mold groove to complete the clamping operation of the fixed coaster and part of the fabric, and makes the corresponding position of the fabric fit tightly with the fixed coaster. Finally, the upper mold 52 performs a heating treatment of the corresponding strength of the part of the fabric and the fixed coaster, so that the fixed coaster and the counter-positioned parts of the fabric are stably connected together, and the heating and shaping treatment of the corresponding position of the corresponding fabric is completed; After the heating and shaping treatment of the cloth and the fixed coaster, the electric-controlled three-way valve 44 is started, so that the interior of the guide tube 43 is connected to the outside. At this time, the excess gas in the piston cylinder 32 passes through the guide tube 43 and is discharged to the outside through the electric-controlled three-way valve 44. As the strength of the high-pressure chamber in the piston cylinder 32 decreases, when the thrust of the gas in the piston cylinder 32 on the piston rod 33 is less than the thrust of the spring 35 on the limit ring 34, due to the push of the spring 35 on the limit ring 34, the piston rod 33 that slides out of the piston cylinder 32 is gradually retracted into the piston cylinder 32 until the clamping plate 24 and the bracket 31 conflict with each other. At this time, the clamping state of the cloth is released, and the operator pulls the cloth to directly extract the processed cloth and the fixed coaster from the gap between the clamping plate 24 and the lower mold 21. According to the above repeated operations, the heating and shaping processing of the cloth and the fixed coaster can be continuously completed.
