Description

Technical Field

[0001] The invention relates to a drying device, in particular to a circulating cleaning drying device for yarn processing. Background Art

[0002] After the bobbin yarn is dyed, it is necessary to first clean the yarn of residual dye liquid (usually by washing and leaching), and then spin dry and dry the yarn. Currently, the cleaning equipment and drying equipment are independent equipment, and the drying and dehydration need to be implemented in two steps. During the dehydration process, the workers judge whether the residual dye liquid in the bobbin yarn has been cleaned by the color depth of the water removed. If it is found that the color of the water removed by the yarn is higher than the color is too dark, it can be determined that the bobbin yarn is not cleaned properly. At this time, the bobbin yarn needs to be lifted out of the dehydration equipment again, and the bobbin yarn needs to be transported back to the cleaning pool by a carrying cart for re-cleaning. During this period, workers need to repeatedly lift and carry the bobbin yarn, which is not only labor-intensive but also very inefficient. Therefore, there is an urgent need for a self-circulating cleaning and drying production line to improve work efficiency and reduce the work intensity of workers. Circulating cleaning and drying equipment. Summary of the invention

[0017] Preferably, the U-shaped groove B is trumpet-shaped, and the opening gradually increases from the direction of the bobbin placement rack to the direction of the bobbin placement rack.

[0018] Preferably, a glass tube connected to the dehydration tank is also provided at the bottom of the tank wall of the dehydration tank.

The mating edges of the movable box, the fixed box and the sealing cover are sealed and mated by locks.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This solution realizes the convenient circulation of the bobbin yarn between the cleaning mechanism and the dehydration mechanism through the circular transmission mechanism, ensuring the uniformity of the yarn color after subsequent drying. It should be noted that under this solution, even if the bobbin yarn is detected to be not cleaned by the dye solution during dehydration, it can be conveniently transferred to the cleaning mechanism through the circular transmission mechanism, which greatly reduces the work intensity of the workers and improves the transfer efficiency during repeated cleaning.

[0025] 2. The conveying frame in this solution sinks in an inverted trapezoidal shape at the cleaning mechanism and the dehydration mechanism, so that the bobbin yarn on the bobbin yarn placement frame can automatically sink into the above structure when passing through the above two mechanisms, and cooperate to complete the bobbin yarn cleaning and dehydration operations.

[0026] 3. The cleaning mechanism in this solution has a slide A, which is provided with a U-shaped groove A. During the descent process of the bobbin rack, the connecting pipe at the bottom of the bobbin rack gradually enters the U-shaped groove A until it contacts the bottom of the U-shaped groove A. Subsequently, the bobbin rack will continue to move forward and descend along one end path. In this downward inclined path, the connecting pipe drives the slide A to move synchronously in the cleaning tank, and the descending connecting pipe is connected to the water outlet pipe on the slide A, providing a guarantee for the subsequent bobbin cleaning. It should be noted that in this solution, when the bobbin rack moves synchronously with the circulating transmission mechanism, the water outlet pipe on the slide A and the connecting pipe at the bottom of the bobbin rack are in a sealed plug-in state, and thus can synchronously drive the movement of the slide A, so that the bobbin yarn can clean itself during the movement, further improving the operating efficiency of the entire equipment.

[0027] 4. The cleaning mechanism adopts the same connection principle as the washing mechanism to realize the connection between the sliding process of the bobbin yarn placement rack and the spline on the slide B, which provides operability for the subsequent high-speed rotation of the bobbin yarn placement rack driven by the motor.

[0028] 5. A glass tube connected to the dehydration tank is set on the outer wall of the dehydration tank to facilitate workers to observe the color of the water removed from the bobbin yarn, and then accurately judge whether the bobbin yarn has been cleaned properly.

[0029] 6. Set up a water baffle to prevent excessive water from splashing out of the dehydration tank during centrifugal dehydration.

[0030] 7. The loading shuttle can be raised and lowered to facilitate workers to hang the bobbin rack on the hook of the circulating transmission mechanism.

[0031] 8. A movable drying box is set on the unloading shuttle bus. After the worker removes the bobbin placement rack from the circulating transmission mechanism, the bobbin can be quickly sent into the drying box, and the bobbin can be quickly transported out of the drying box after drying, which greatly improves the drying efficiency of the bobbin.

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] like Figures 1 to 12 The yarn processing circulating cleaning and drying device shown in the figure comprises a circular transmission mechanism 1 and a cleaning mechanism 6 and a dehydration mechanism 5 which are arranged in sequence on the travel path of the circular transmission mechanism 1. Figure 1 As shown, the circulating transmission mechanism is provided with a loading and unloading station 13 for hanging and unloading the bobbin rack on the circulating transmission mechanism on the path between the dehydration mechanism and the cleaning mechanism. In addition, it should be noted that a drying box 4 is also provided beside the loading and unloading station 13 to dry the dehydrated bobbin unloaded from the circulating transmission mechanism nearby.

[0055] It should be noted that in the above-mentioned equipment, the transportation of the bobbin yarn requires the use of a loading shuttle 2 and a unloading shuttle 3. Among them, the loading shuttle is used to transport the bobbin yarn to be processed to the loading and unloading stations of the circulating transmission mechanism, while the unloading shuttle is used to unload the bobbin yarn that has been thoroughly cleaned and dehydrated from the circulating transmission mechanism and transport it to the drying box 4.

[0056] In addition, it should be noted that in the present solution, when the circulating transmission mechanism passes over the cleaning mechanism and the dehydration mechanism, it can guide the suspended bobbin yarn placement rack to descend and sink into the cleaning mechanism 6 and the dehydration mechanism 5 located directly below it, so that the bobbin yarn on the bobbin yarn placement rack can be cleaned and dehydrated in the corresponding mechanism.

[0057] Specifically, in order to realize the above-mentioned driving of the bobbin yarn on the bobbin yarn placement rack 7 to enter the dehydration mechanism and the cleaning mechanism by itself. The circulating transmission mechanism 1 in this scheme includes a conveyor frame 11, which includes a guide rail erected above the cleaning mechanism and the dehydration mechanism and a transmission chain system running on the guide rail. At the same time, it also includes a plurality of hooks 12, which are evenly distributed on the chain of the conveyor frame to follow the running chain and move in a circle on the conveyor frame. It should be noted that, as Figure 1 As shown, when the guide rail of the conveyor frame is about to enter the cleaning mechanism 6 and the dewatering mechanism 5, it has a tendency to tilt downward to ensure that the bobbin rack hoisted on the hook can move downward synchronously when it moves to the cleaning mechanism and the dewatering mechanism. At the same time, the guide rail has a tendency to tilt upward on the path of moving out of the cleaning mechanism and the dewatering mechanism to ensure that the hoisted bobbin rack can rise synchronously while moving forward to avoid collision with the dewatering mechanism and the cleaning mechanism. Specifically, the part of the conveyor frame located above the dewatering mechanism and the cleaning mechanism is in an inverted trapezoidal shape as a whole, which ensures that the bobbin rack can automatically avoid and prevent collision when entering and exiting the dewatering mechanism and the cleaning mechanism, and the middle horizontal part can also keep the bobbin rack in stable contact with the dewatering mechanism and the cleaning mechanism, so as to synchronously complete the cleaning and dewatering of the bobbin during the process of moving.

[0058] Specifically, Figure 3 , Figure 7 , Fig.10 as well as Fig.12 As shown, after the bobbin placement rack enters the cleaning mechanism 6, the bobbin cleaning process can be completed while moving through the following structure cooperation.

[0059] Specifically, the cleaning mechanism 6 includes a cleaning tank 61 placed directly below the conveyor frame 11, and the bottom of the cleaning tank 61 is provided with at least two guide rods A62 extending along the horizontal direction of the conveyor frame 11, and a slide A64 is installed on the guide rod A in a sliding manner. It should be noted that a U-shaped groove A64a is provided on the slide A, and the opening of the U-shaped groove A is open to the direction of the bobbin yarn placement rack. When the bobbin yarn placement rack descends obliquely into the cleaning tank, the connecting pipe 72 arranged at the bottom of the bobbin yarn placement rack can first enter the U-shaped groove A, and after contacting the bottom of the U-shaped groove A, it completes the connection with the slide A, and subsequently realizes the function of the bobbin yarn placement rack driving the slide A to move forward synchronously. It should be noted that after the connection between the slide A and the bobbin yarn placement rack is completed, the following structure is also required to complete the cleaning of the bobbin yarn on the bobbin yarn placement rack after the connection. Specifically, a water outlet pipe 66 is coaxially arranged at the bottom of the U-shaped groove A. The height of the water outlet pipe is lower than the height of the slide A to ensure that when the connecting pipe of the bobbin placement rack A comes into contact with the bottom of the U-shaped groove, the connecting pipe will not interfere with or collide with the water outlet pipe. It should be noted that after the connecting pipe comes into contact with the bottom of the U-shaped groove A, the bobbin placement rack will drop a certain height under the guidance of the conveying frame. At this time, the connecting pipe will be sealed and inserted into the water outlet pipe to achieve connection with the water outlet pipe. It should be noted that if the connecting pipe of the bobbin placement rack A comes into contact with the bottom of the U-shaped groove A, the bobbin placement rack will drop a certain height under the guidance of the conveying frame. Fig.10 as well as Fig.12 As shown, the outlet pipe in this scheme is connected to the high-pressure pump 65 installed on the side of the slide through the channel 64b opened in the slide A64. When the high-pressure pump pumps the high-pressure cleaning liquid outward, the cleaning liquid can enter the bottom support 71 through the connecting pipe on the bobbin placement rack, and finally pumped out by the porous tube group above the bottom support, and the bobbin yarn is stringed on the porous tube group to achieve the cleaning of the bobbin yarn. It should also be noted that in order to prevent the high-pressure pump from starting when the bobbin yarn placement rack is not connected, the cleaning liquid is sprayed out of the cleaning tank from the outlet pipe. A pressure plate A67 is also slidably sleeved on the outlet pipe in this scheme, and a spring B69 is installed at the bottom of the pressure plate A to support the pressure plate A. At the same time, an L-shaped gate plate 68 is also connected to one side of the pressure plate A, and the gate plate slides and cooperates to cross the channel 64b opened in the slide A to block the channel. At the same time, a through hole is also provided on the gate plate. When the pressure plate A is pressed down by the connected bobbin yarn placement rack, the through hole sinks into the channel and the channel remains connected. In addition, in the present scheme, a pressure switch A610 is also provided. When the pressure plate A is pressed down, the pressure switch A is pressed down, thereby starting the high-pressure pump connected to the electrical signal of the pressure switch A. It should also be noted that after the cleaning of the bobbin yarn on a bobbin yarn placement rack is completed, the slide A needs to be returned to its original position. For this purpose, a spring A63 is also provided on the guide rod A. When the slide A moves driven by the connected bobbin yarn placement rack, the spring A63 is compressed. When the bobbin yarn placement rack is out of contact with the slide A, the slide A is pushed back to the initial stage by the rebounding spring A.

[0060] It should be noted that, as a preferred embodiment of the above embodiment, the U-shaped groove A is a trumpet-shaped structure, and the opening gradually increases from the direction of the bobbin yarn placement rack to the direction of the bobbin yarn placement rack, so as to ensure that the connecting pipe at the bottom of the bobbin yarn placement rack can smoothly enter the U-shaped groove A.

[0061] In addition, it should be noted that in this solution, after the bobbin placement rack enters the dehydration mechanism 5, the bobbin yarn on the bobbin placement rack can be automatically dehydrated. Figure 2 , Figure 6 as well as Fig. 9 , Fig.11 As shown, the dehydration mechanism specifically includes a dehydration trough 51, and the bottom of the dehydration trough is also provided with at least two guide rods B53 extending in parallel along the horizontal direction of the conveying frame above it. At the same time, a slide B57 capable of sliding along the axial direction of the guide rod B is slidably installed on the guide rod B. It should be noted that a U-shaped groove B57a is provided on the slide B. When the descending bobbin yarn placement rack enters the dehydration trough, the connecting pipe under the bobbin yarn placement rack first enters the U-shaped groove B, and after contacting the bottom of the U-shaped groove B, the connection between the two is completed, and the slide B can be driven to move forward synchronously. It should be noted that in this solution, a motor 55 with a waterproof function is also installed at the bottom of the slide B. The output shaft of the motor can rotate through the slide B and extend into the U-shaped groove B. At the same time, there is a spline 56 coaxially connected to the output shaft of the motor. When the connection between the bobbin rack and the slide B is completed, the spline enters the connecting tube at the bottom of the bobbin rack and is inserted into the spline groove 72a opened in the connecting tube 72 without relative rotation. At this time, when the motor rotates at high speed, it can drive the bobbin rack connected to it to rotate with it, thereby realizing the centrifugal dehydration of the bobbin on the bobbin rack. It should be noted that in order to ensure that the motor rotates only after the connection between the bobbin rack and the slide B is completed, as shown in FIG. Fig. 9 , Fig.11 As shown, a pressure plate B59 is sleeved on the output shaft of the motor extending into the U-shaped groove B, and a spring D58 is provided at the bottom of the pressure plate B to support the pressure plate B. At the same time, a pressure switch B511 is installed at the bottom of the U-shaped groove B. When the pressure plate B drops to a certain height under the pressure of the bobbin placement rack, the pressure plate B presses the pressure switch B, thereby starting the motor 55 connected to the electrical signal of the pressure switch. In addition, it should be noted that in order to enable the bobbin placement rack to rotate smoothly, a rotating disk 510 is also rotatably installed on the upper surface of the pressure plate B59, and the rotating disk is connected to the pressure plate B through a slip ring. When the motor drives the bobbin placement rack to rotate, it can ensure that the pressure plate B does not rotate, thereby preventing the spring D from twisting.

[0062] It should also be noted that in order to achieve the reuse of slide B in this solution, a spring C54 is also provided on the guide rod B. When slide B moves forward driven by the bobbin yarn placement rack, spring C is compressed. When the bobbin yarn placement rack loses contact with slide B, spring C immediately resets and pushes slide B to its initial position.

[0063] As a preferred embodiment of the above method, the U-shaped groove B57a is also trumpet-shaped, and specifically the opening gradually increases from the direction of the bobbin yarn placement rack to the direction of the bobbin yarn placement rack, so that the connecting tube 72 at the bottom of the bobbin yarn placement rack can smoothly enter the U-shaped groove B.

[0064] It should also be noted that, in the dehydration process, workers need to visually judge whether the previous yarn package is cleaned properly by the color of the water released. In order to conveniently observe the water released from the yarn package, a glass tube 52 is provided at the bottom of the dehydration tank 51. The glass tube is a connecting tube structure, so that the released water can flow through the glass tube, which is convenient for workers to observe.

[0065] It should also be noted that when centrifugal dehydration is performed, the water in the bobbin is thrown out at high speed, in order to avoid the excessive water being thrown out in the workshop environment. A fixed water baffle 512 is also provided on both sides of the dehydration tank, and the height of the fixed water baffle is higher than the height of the bobbin placement rack sunk into the dehydration tank. At the same time, two movable water baffles 513 are installed at both ends of the bobbin placement rack entering and exiting the dehydration tank. It should be noted that the movable water baffle is on the path of the traveling bobbin placement rack. In order to avoid the movable water baffle from interfering with the bobbin placement rack, the movable water baffle 513 can be elastically flipped toward the direction of the bobbin placement rack, so that the bobbin placement rack can avoid the bobbin placement rack through the movable water baffle, and reset itself after the bobbin placement rack leaves.

[0066] In addition, in this solution, the height of the loading and unloading stations 13 of the conveyor frame 11 is higher than the height of the bobbin placement rack 7. Therefore, when loading and unloading the bobbin placement rack at the loading and unloading stations, the bobbin placement rack needs to be kept at a height that can be connected to the hook. Figure 4 As shown, the specific structure of the loading shuttle 2 in this scheme includes a mobile frame A21 that can be easily pulled by workers, and at least one telescopic cylinder A22 is installed on the mobile frame A, and a support tray A23 is installed horizontally on the end of the telescopic rod of the telescopic cylinder A. It should be noted that in order to adapt to the protruding connecting pipe structure at the bottom of the bobbin yarn placement rack, the support tray A has a through hole 23a in the middle to avoid the connecting pipe at the bottom of the bobbin yarn placement rack. When the bobbin yarn placement rack needs to be hoisted onto the hook, the loading shuttle is pushed to the loading and unloading stations, and then the bobbin yarn placement rack is raised by the telescopic cylinder A so that the ring 73 on the bobbin yarn placement rack can be hung with the hook.

[0067] At the same time, the material unloading shuttle 3 in this scheme has a specific structure including a mobile frame B31, on which at least one telescopic cylinder B32 capable of vertical extension is installed, and a support tray B33 is fixedly installed on the end of the telescopic rod of the telescopic cylinder. When it is necessary to unload the bobbin rack 7 from the hooks at the upper and lower material stations 13, the worker moves the material unloading shuttle to the bottom of the bobbin rack at the upper and lower material stations, and then raises the support tray B through the telescopic cylinder B so that the bobbin rack can be placed on the support tray B, and at this time, the hook and the ring can be easily disengaged.

[0068] It should be noted that in the present scheme, in order to reduce the steps of hoisting the bobbin yarn placement rack such as the drying box 4 in the subsequent drying process. The drying box in the present scheme adopts a combined structure integrated with the unloading shuttle bus. That is, after the unloading shuttle bus receives the unloaded bobbin yarn placement rack, it can be directly sent to the drying box for drying without the need for subsequent re-hoisting operations. Specifically, the drying box 4 includes a box body 41, which is vertically divided into a fixed box 41a and a movable box 41b along the center line. Among them, the fixed box is fixed to the ground by means of suspended legs, and the movable box is fixed on the supporting tray B of the unloading shuttle bus. It should be noted that in the present scheme, the supporting tray B plays a role of sealing the bottom of the box body after the movable box and the fixed box are matched. For this reason, Figure 5 As shown, the bottom of the tray has a downward depression, but the whole is not through. At the same time, a sealing cover 42 is also installed on the fixed box. When the movable box is matched with the fixed box under the drive of the unloading shuttle, the movable box, the sealing cover and the fixed box are sealed and locked by the lock buckles set on the edge of the fixed box and the edge of the sealing cover. At this time, the bobbins on the bobbin placement rack can be dried in the drying box 4, and can be directly towed away after drying and cooling, without the need for complicated lifting work.

[0069] It should be noted that the bobbin rack in this solution is a traditional structure, specifically including a base bracket 71 for support, which is a hollow structure, and a connecting tube 72 is coaxially arranged at the bottom of the base bracket, which is connected to the base bracket, and a spline groove 72a is arranged in the connecting tube to ensure that the bobbin rack can be driven to rotate together after the subsequent spline is inserted. In addition, multiple groups of porous tube groups 74 are arranged on the upper surface of the base bracket for stringing bobbins. Finally, a hanging ring 73 is also installed in the center of the base to facilitate the subsequent connection with the hook.

[0070] In addition, it should be noted that in this solution, the hook can be an electronic hook, so that the bobbin placement rack can be more efficiently installed and unloaded. In addition, the hook itself has a rotation function, so that it can follow the rotation when the bobbin placement rack rotates.

[0071] Working principle: When the bobbin yarn needs to be cleaned and dried, the staff will first string the bobbin yarn on the porous tube of the bobbin yarn placement rack, and then hoist the bobbin yarn placement rack onto the loading shuttle, and transport it to the loading and unloading stations through the loading shuttle. Then, the worker raises the supporting tray A of the loading shuttle so that the hook can be combined with the lifting ring on the bobbin yarn placement rack. After completing the above operations, lower the supporting tray A of the loading shuttle to the initial position again, and the bobbin yarn placement rack is in a suspended state. It should be noted that because the dehydration and cleaning of the bobbin yarn in this scheme take a long time, the running speed of the circulating transmission mechanism in this scheme is very slow, at 0.2~0.3m / min. Workers are fully capable of safely operating the hoisting bobbin yarn placement rack.

[0072] When the bobbin yarn placement rack is hoisted, the bobbin yarn placement rack comes to the cleaning mechanism along with the running circulation transmission mechanism and sinks into it to complete the connection with the slide A. At this time, the pressure plate A in the water cleaning mechanism is pressed down by the descending bobbin yarn placement rack and triggers the pressure switch A, thereby starting the high-pressure pump to pump cleaning liquid into the bobbin yarn placement rack, and the bobbin yarn can be cleaned.

[0073] When the cleaning is completed, the bobbin rack is guided by the rising circulation transmission mechanism to rise and leave the slide A. At this time, the pressure plate A is also reset, the pressure switch is closed, and the high-pressure pump stops pumping water. The bobbin rack is then moved out of the cleaning tank.

[0074] Next, the bobbin rack comes to the dewatering mechanism along with the running circulation transmission mechanism. The bobbin rack then sinks into the dewatering tank under the guidance of the inclined descending circulation transmission mechanism, and completes the connection between the connecting tube in the bobbin rack and the slide B. At this time, the spline in the dewatering mechanism is inserted into the spline groove opened in the connecting tube, and after the connecting tube presses down the pressure plate B, the pressure switch B starts the motor. As the motor rotates, the bobbin rack also rotates at high speed, thereby realizing centrifugal dehydration. When the centrifugal dehydration is completed, the bobbin rack immediately detaches from the slide B under the guidance of the raised circulation transmission mechanism. At this time, the pressure plate B is also reset, the pressure switch B is closed, the motor stops rotating, and the bobbin rack follows the circulation transmission mechanism to return to the loading and unloading stations.

[0075] At this time, if the cleaning effect is observed to be as expected through the glass tube during the dehydration process, the worker will use the unloading shuttle to remove the bobbin rack from the circulating transmission mechanism and send it to the fixed box. Then adjust the position of the unloading shuttle so that the movable box and the fixed box are aligned, and then use the lock to seal the two. At this time, high-temperature air can be introduced into the box through the steam pipe on the fixed box to achieve the drying operation of the bobbin. If it is observed that the water color during dehydration is darker, the bobbin rack will continue to be hung on the circulating transmission mechanism, and the cleaning and dehydration operations will be repeated until the cleaning meets the required requirements.

[0076] Through the above mechanism, this solution realizes cyclic cleaning and convenient drying operation during the yarn processing, greatly improving the yarn processing efficiency.

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