Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically a positioning flat sewing machine for processing clothing and bedding. Background Technology

[0002] Bedding refers to items placed on a bed for use while sleeping, including quilts, duvet covers, sheets, bedspreads, fitted sheets, pillowcases, pillow inserts, blankets, mats, and mosquito nets.

[0003] A flatbed sewing machine is a machine that uses a single sewing thread to create a stitch on the fabric, allowing one or more layers of fabric to interweave or sew together. It is generally divided into two types: one for thin fabrics and one for thick fabrics. Flatbed sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. Thin fabrics are generally used for knitwear, underwear, shirts, uniforms, etc.

[0004] Currently, flatbed sewing machines on the market lack restrictive and positioning components for the fabric during transport, which can cause the fabric to become skewed. In addition, flatbed sewing machines only have the function of sewing fabric, and existing flatbed sewing machines cannot integrate the function of guiding and transporting fabric and ironing and drying simultaneously. Therefore, an improved device is needed to address the above problems. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a positioning flat sewing machine for processing clothing and bedding.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a positioning flat sewing machine for processing clothing and bedding, including a support mechanism, a transmission device fixedly installed at the top front end of the support mechanism, and a positioning device fixedly installed at the top rear end of the support mechanism.

[0007] The positioning device includes a first positioning plate, a first spring, a first support plate, and a first plastic roller conveyor. The first spring is symmetrically and fixedly installed at the bottom end of the first support plate. The first positioning plate is fixedly installed at the bottom end of the first spring. The first plastic roller conveyor is rotatably installed inside the bottom end of the first positioning plate. When the first support plate moves downward, it can be compressed by the first spring to achieve buffering of the first positioning plate.

[0008] The transmission device includes a drive motor, a first gear, a second plastic roller conveyor, and a second positioning plate;

[0009] The second plastic roller is rotatably installed inside the bottom of the second positioning plate, and the second plastic roller passes through the second positioning plate and is connected to the first gear.

[0015] Specifically, the guiding device includes a second gear and a connecting rod;

[0016] The connecting rod is rotatably mounted on the left side of the second gear, and a connecting base plate is rotatably mounted on the rear right side of the connecting rod. A synchronizing rod is mounted on the top of the connecting base plate, and four air supply chambers are equidistantly arranged on the side end of the synchronizing rod away from the connecting rod.

[0017] When the second gear rotates, it can cyclically drive the connecting base plate and the connecting rod to move, so that the synchronizing rod can move in a straight line inside the movable groove, and the air supply cavity can move at a constant speed inside the protective base plate.

[0018] Specifically, the conveying device includes a transmission toothed belt, on which four third gears are symmetrically meshed, and a fourth gear is installed on the right side of the third gear near the front end.

[0019] The third gear is equipped with a support shaft at its center, and the two support shafts are rotatably mounted inside the protective base plate.

[0020] The fourth gear meshes with the second gear, allowing the second gear to drive the fourth gear and the transmission belt to rotate synchronously.

[0021] Specifically, the limiting device includes a protective base plate, a support platform, and a computerized sewing machine;

[0022] The computerized sewing machine is fixedly installed on the top right side of the support platform. The support platform is fixedly installed on the top of the protective base plate. The front end of the support platform has equidistant vent holes. A guide cavity is slidably inserted into the left side of the support platform near the vent holes. A movable groove is opened on the top side of the support platform near the computerized sewing machine, and the movable groove is located below the computerized sewing machine. A fifth gear is rotatably installed on the front end of the computerized sewing machine near the support platform. A protrusion is installed on the side surface of the fifth gear facing away from the support platform. A receiving cavity is fixedly installed at the bottom rear end of the protective base plate.

[0023] The exhaust port is vertically aligned with the flow guide cavity. A guide plate is installed at the front end of the inner side of the protective substrate. A 45° inclined plate is installed at the bottom of the inner side of the flow guide cavity. A discharge groove is opened at the bottom of the flow guide cavity away from the support platform.

[0024] The guide ramp inside the protective substrate is flush with the top of the transmission toothed belt, allowing the interior of the protective substrate to communicate with the top of the transmission toothed belt.

[0025] Specifically, a hexagonal support rod is fixedly installed at the top of the sealing rubber plug, and the hexagonal support rod is slidably inserted into the top of the transfer cavity. Sliding rods are symmetrically fixedly installed at the top of the second positioning plate and the first positioning plate, and the sliding rods pass through the interior of the second support plate and the first support plate respectively.

[0026] Specifically, the rear end of the extension rod is connected to the extension plate, a connecting pipe is installed between the ironing head and the auxiliary device, the second gear is rotatably installed on the side of the protective base plate near the fifth gear, the synchronizing rod is slidably inserted into the inside of the movable groove, and the fourth gear, the second gear, the fifth gear and the first gear mesh.

[0027] Specifically, the air supply cavity is vertically aligned with the transmission toothed belt, and the second and first plastic roller tracks are vertically aligned with the support platform.

[0028] Specifically, the protective substrate includes a vertical guide rail, which is fixedly installed on both rear ends of the protective substrate. The receiving cavity also includes a limiting post and an extension sleeve, which is fixedly installed on both front ends of the receiving cavity. The limiting post is slidably inserted into the extension sleeve on the outer side of the receiving cavity away from the receiving cavity.

[0029] The beneficial effects of this invention are:

[0030] First, when the drive motor starts, the invention can drive the second plastic roller conveyor to transport the fabric to the front end, and the first plastic roller conveyor can press the rear end of the fabric, so that the fabric can move to the front end in a straight line. At the same time, when the second plastic roller conveyor rotates, the first gear can drive the fourth gear to rotate, so that when the fourth gear rotates, it can drive the fallen fabric to the rear end through the transmission tooth belt, so that the fabric can return again, thus completing the work of guiding and transporting the fabric.

[0031] Second, when the fifth gear rotates, it can drive the protrusion to contact the extension protrusion, allowing the guide rod to be squeezed into the interior of the transfer cavity. This allows water inside the transfer cavity to enter the interior of the ironing machine body, replenishing the water source inside the ironing machine body. At the same time, by vertically aligning the ironing head with the support table, the fabric can be ironed. Furthermore, when the fabric is transported on the transmission belt, the rotation of the second gear can drive the air supply cavity to reciprocate within the protective base plate, allowing the air supply cavity to reciprocate above the fabric, thereby evenly spraying hot air onto the fabric, completing the synchronized ironing and drying of the fabric.

Detailed Implementation

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0045] The invention will be further described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a positioning flat sewing machine for processing clothing and bedding products according to the present invention includes a support mechanism 3, a transmission device 2 is fixedly installed at the top front end of the support mechanism 3, and a positioning device 1 is fixedly installed at the top rear end of the support mechanism 3.

[0048] The positioning device 1 includes a first support plate 4, a first spring 5, a first positioning plate 6, and a first plastic roller conveyor 7. The first spring 5 is symmetrically fixedly installed at the bottom end of the first support plate 4, the first positioning plate 6 is fixedly installed at the bottom end of the first spring 5, and the first plastic roller conveyor 7 is rotatably installed inside the bottom end of the first positioning plate 6. When the first support plate 4 moves downward, it can be compressed by the first spring 5 to achieve the buffering treatment of the first positioning plate 6.

[0049] The transmission device 2 includes a drive motor 8, a first gear 9, a second plastic roller conveyor 10, and a second positioning plate 11;

[0050] The second plastic roller conveyor 10 is rotatably installed inside the bottom end of the second positioning plate 11, and the second plastic roller conveyor 10 passes through the second positioning plate 11 and is connected to the first gear 9. The first gear 9 is fixedly installed at the center of the side end of the drive motor 8, and the drive motor 8 is fixedly installed on the right side of the second positioning plate 11. The top end of the second positioning plate 11 is symmetrically provided with second springs 12, and the top end of the two second springs 12 is provided with second support plates 13. The top end of the rear end of the second positioning plate 11 is symmetrically provided with extension rods 14. When the drive motor 8 starts, it can drive the fifth gear 38 and the second plastic roller conveyor 10 to rotate synchronously through the first gear 9, so that the second plastic roller conveyor 10 can drive the fifth gear 38 to rotate while conveying the fabric, and then the protrusion 39 can lift the extension protrusion 23.

[0051] like Figure 5The support mechanism 3 includes a guide device 15, a conveying device 16, an extension plate 17, and a limiting device 19. The conveying device 16 is installed at the bottom inside the limiting device 19. The guide device 15 is installed on the right side of the limiting device 19. The auxiliary device 20 is installed on the top of the limiting device 19 near the guide device 15. An ironing head 18 is fixedly installed on the left side of the auxiliary device 20. Two extension plates 17 are provided at the top front end of the ironing head 18. The extension plates 17 are connected to the extension rod 14, so that when the second positioning plate 11 rises, it can drive the ironing head 18 to rise, so that the fabric can pass under the second plastic roller track 10 and the ironing head 18.

[0052] As shown in Figure 6, the auxiliary device 20 includes the ironing machine body 22 and the transfer cavity 27;

[0053] The transfer cavity 27 is fixedly installed at the top of the ironing machine body 22. A guide key 24 is slidably sleeved inside the front end of the ironing machine body 22. An extension protrusion 23 is fixedly installed at the front end of the guide key 24. A guide rod 21 is fixedly installed at the top of the rear end of the guide key 24 away from the extension protrusion 23. A third spring 26 is installed in the center of the interior of the transfer cavity 27. A sealing rubber plug 25 is fixedly installed at the center of the bottom end of the third spring 26.

[0054] A positioning plate is installed at the top center of the transfer cavity 27, and the top center of the sealing rubber plug 25 penetrates the inner center of the positioning plate. A slot adapted to the guide key 24 is opened inside the front end of the ironing machine body 22, and the extension protrusion 23 slides inside the ironing machine body 22. A release hole is opened at the bottom center of the transfer cavity 27, and the guide rod 21 is vertically aligned with the release hole.

[0055] When the extension rod 23 moves upward, it can drive the guide rod 21 to push the sealing plug 25 upward, thereby enabling communication between the transfer cavity 27 and the ironing machine body 22. Furthermore, when the extension rod 23 is not under pressure, the third spring 26 can drive the sealing plug 25 to seal the bottom of the transfer cavity 27. Since the diameter of the guide rod 21 is smaller than the diameter of the sealing plug 25, when the guide rod 21 squeezes the sealing plug 25, water inside the transfer cavity 27 can flow into the ironing machine body 22.

[0056] like Figure 7 The guide device 15 includes a second gear 29 and a connecting rod 28;

[0057] The connecting rod 28 is rotatably mounted on the left side of the second gear 29. The connecting base plate 32 is rotatably mounted on the right rear end of the connecting rod 28. The top of the connecting base plate 32 is equipped with a synchronizing rod 31. The synchronizing rod 31 is equidistantly provided with four air supply chambers 30 on its side end away from the connecting rod 28.

[0058] When the second gear 29 rotates, it can cyclically drive the connecting base plate 32 and the connecting rod 28 to move, so that the synchronizing rod 31 can move in a straight line inside the movable groove 37, and the air supply cavity 30 can move at a constant speed inside the protective base plate 40. Through the meshing of the second gear 29 and the fifth gear 38, the fifth gear 38 can drive the second gear 29 to rotate while rotating.

[0059] like Figure 8 The conveying device 16 includes a transmission toothed belt 33, and four third gears 34 are symmetrically meshed inside the transmission toothed belt 33. A fourth gear 35 is installed on the right side of the third gear 34 near the front end.

[0060] The third gear 34 has a support shaft installed at its center, and the two support shafts are rotatably installed inside the protective base plate 40.

[0061] The fourth gear 35 meshes with the second gear 29, so that the second gear 29 can drive the fourth gear 35 and the transmission belt 33 to rotate synchronously. When the transmission belt 33 is rotating, it can transport the fabric.

[0062] like Figure 9 The limiting device 19 includes a protective base plate 40, a support table 44, and a computerized sewing machine 43;

[0063] The computer sewing machine 43 is fixedly installed on the top right side of the support platform 44. The support platform 44 is fixedly installed on the top of the protective base plate 40. The front end of the support platform 44 has equidistant exhaust holes 42. The left side of the support platform 44 near the exhaust holes 42 is slidably inserted into the guide cavity 41. The top side of the support platform 44 near the computer sewing machine 43 has a movable groove 37, which is located below the computer sewing machine 43. The computer sewing machine 43 has a fifth gear 38 rotatably installed on the front end near the support platform 44. The fifth gear 38 has a protrusion 39 installed on the side surface of the support platform 44 away from the support platform 44. The bottom rear end of the protective base plate 40 has a receiving cavity 36 fixedly installed. The protective base plate 40 is hollow inside, which allows the transmission belt 33, the third gear 34 and the fourth gear 35 to be installed inside the protective base plate 40.

[0064] The exhaust port 42 is vertically aligned with the flow guide cavity 41. A guide plate is installed at the front end of the inner side of the protective substrate 40. A 45° inclined plate is installed at the bottom of the inner side of the flow guide cavity 41. A discharge groove is opened at the bottom of the flow guide cavity 41 away from the support platform 44.

[0065] The guide ramp inside the protective substrate 40 is flush with the top of the transmission toothed belt 33, allowing the interior of the protective substrate 40 to communicate with the top of the transmission toothed belt 33.

[0066] A hexagonal support rod is fixedly installed at the top of the sealed rubber plug 25, and the hexagonal support rod is slidably inserted into the top of the transfer cavity 27. Sliding rods are symmetrically fixedly installed at the top of the second positioning plate 11 and the first positioning plate 6, and the sliding rods pass through the interior of the second support plate 13 and the first support plate 4 respectively. The rear end of the extended rod 14 is connected to the extension plate 17. A connecting pipe is installed between the ironing head 18 and the auxiliary device 20. The second gear 29 is rotatably installed on the side of the protective base plate 40 near the fifth gear 38. The synchronizing rod 31 is slidably inserted into the interior of the movable groove 37. The fourth gear 35, the second gear 29, the fifth gear 38 and the first gear 9 mesh. The air supply cavity 30 is vertically aligned with the transmission toothed belt 33. The second plastic roller track 10 and the first plastic roller track 7 are vertically aligned with the support table 44.

[0067] The working principle of Example 1 is as follows: When in use, first pull the first positioning plate 6 upward, then let the fabric pass through the bottom end of the first plastic roller track 7 and contact the bottom end of the computer sewing machine 43, then start the computer sewing machine 43 so that the front end of the fabric can be sewn.

[0068] Then, the second positioning plate 11 can be moved upward until the front end of the fabric moves below the second plastic roller 10. Then, the second positioning plate 11 and the first positioning plate 6 are released at the same time. At this time, the elasticity of the first spring 5 and the second spring 12 will drive the second positioning plate 11 and the first positioning plate 6 to move downward at the same time until the first plastic roller 7 and the second plastic roller 10 can press the fabric.

[0069] Subsequently, the drive motor 8 can be started, driving the first gear 9 and the second plastic roller 10 to rotate. When the second plastic roller 10 rotates, it can pull the fabric to the front end, so that the computer sewing machine 43 can sew the fabric at different positions. When the fabric is being conveyed to the front end, the ironing machine body 22 can be started, so that steam can be sprayed out from the inside of the ironing head 18. At the same time, the ironing head 18 is located above the fabric, so that the ironing head 18 irons the fabric. Meanwhile, the steam can pass through the inside of the exhaust hole 42, and finally the steam can condense inside the guide cavity 41. A release hole is provided on the right side of the inside of the guide cavity 41, so that water droplets can flow into the release hole through the guide plate inside the guide cavity 41, thus completing the steam discharge work.

[0070] Subsequently, when the first gear 9 rotates, it can drive the fifth gear 38 to rotate simultaneously. When the fifth gear 38 drives the protruding part of the protrusion 39 to rotate until it contacts the extension protrusion 23, it can squeeze the extension protrusion 23 to move upward. It slides into the slot inside the front end of the ironing machine body 22 through the guide key 24, so that the guide rod 21 can move upward in a straight line, so that the guide rod 21 can squeeze the sealing rubber plug 25 to move upward. Through the transfer cavity 27, it is pre-connected to the external water pipe, so that the water pipe can transmit water into the interior of the transfer cavity 27. When the sealing rubber plug 25 is disengaged from the bottom end of the transfer cavity 27, the water can flow into the interior of the ironing machine body 22 through the release hole at the bottom end of the transfer cavity 27.

[0071] When the protruding part of the protrusion 39 passes the bottom end of the extension protrusion 23, the elasticity of the third spring 26 will cause the sealing plug 25 to move rapidly downward, so that the sealing plug 25 can seal the release hole at the bottom end of the transfer cavity 27, preventing excessive water from flowing into the ironing machine body 22, completing the intermittent water replenishment work inside the ironing machine body 22. Furthermore, because the transmission ratio of the first gear 9 and the fifth gear 38 is 50:1, the first gear 9 will not drive the fifth gear 38 to rotate rapidly. Simultaneously, through the... The fifth gear 38 meshes with the second gear 29, and the second gear 29 meshes with the fourth gear 35, so that when the fifth gear 38 rotates, it can drive the third gear 34 to rotate through the fourth gear 35, so that the transmission belt 33 can rotate at the same time. When the second plastic roller conveyor 10 is conveying the fabric, the fabric will fall from the front end of the support platform 44 into the interior of the protective base plate 40. At the same time, a guide plate is fixedly installed at the front end of the interior of the protective base plate 40, so that the fabric can enter the top of the transmission belt 33 along the guide plate.

[0072] When the transmission belt 33 rotates, it can transport the fabric to the rear end, completing the synchronous transport of the fabric. At the same time, when the second gear 29 rotates, it can drive the connecting rod 28 to rotate, so that the connecting rod 28 can reciprocate to push the connecting base plate 32 and the synchronizing rod 31 to move. Through the movement of the synchronizing rod 31 inside the movable groove 37, it can support the air supply chamber 30 to move in a straight line. Through the connection of the air supply chamber 30 with the external hot air machine pipe, the external hot air machine can be started, so that the air supply chamber 30 can transport hot air above the transmission belt 33. At this time, when the air supply chamber 30 reciprocates on the fabric, it can improve the drying uniformity of the fabric.

[0073] Subsequently, when the transmission belt 33 transports the fabric to the end near the receiving cavity 36, the fabric will fall from the transmission belt 33 into the inside of the receiving cavity 36 for collection, completing the overall sewing and ironing work of the fabric. When this device is in use, several grooves are equally spaced on the outer surface of the transmission belt 33, so that when the air supply cavity 30 supplies air to the top of the transmission belt 33, the fabric can be prevented from slipping, thus completing the work.

[0074] Example 2

[0075] Based on Example 1, such as Figure 10 As shown, the protective substrate 40 includes a vertical guide rail 45, which is fixedly installed on both rear ends of the protective substrate 40. The receiving cavity 36 also includes a limiting post 46 and an extension sleeve 47, which is fixedly installed on both front ends of the receiving cavity 36. The limiting post 46 is slidably inserted into the extension sleeve 47 on the outside of the receiving cavity 36.

[0076] In implementing this embodiment, when a certain amount of fabric accumulates inside the receiving cavity 36, the receiving cavity 36 can be moved upwards and slidably fitted onto the vertical guide rail 45 via the extension sleeve 47, ensuring that the receiving cavity 36 moves upwards in a straight line. When the receiving cavity 36 moves upwards to its limit position, it can drive the limiting post 46 to be vertically aligned with the round hole on the side of the vertical guide rail 45 away from the protective substrate 40. At this time, the limiting post 46 can be moved and inserted into the round hole on the outside of the vertical guide rail 45, so that the receiving cavity 36 can be supported and placed in a suspended state, making it convenient for the user to place the fabric that needs to be sewn again above the support table 44 to complete the work.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
