Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spinning frame roller, and particularly relates to a spinning frame roller placing device. BACKGROUND

[0002] The spinning frame is a spinning machine that stretches, twists and winds the semi-finished product of roving or sliver into a spinning tube. The roller is one of the main parts of the drafting device of the spinning frame. The center of the roller is a steel roller, and the outer part is covered with leather or artificial rubber. The roller needs to be replaced and maintained regularly in actual production, and therefore the unused roller needs to be placed.

[0003] A spinning frame roller placing device is disclosed in Chinese Patent Publication No. CN215618026U. In this scheme, the cover plate is first opened, and then a plurality of spinning frame rollers are placed in the grooves of the placing rack. Therefore, the size of the groove is determined according to the size of the spinning frame roller to ensure that the plurality of spinning frame rollers do not interfere with each other. Then, the cover plate is closed, and the lock is locked. At this time, the pressing strip presses the plurality of spinning frame rollers to prevent them from falling. Then, the moving frame is moved to the work site. When the temperature of the spinning frame roller inside the moving frame reaches the temperature of the work site, the spinning frame roller can be used. In addition, the design of the vent holes on the roller box and the cover plate speeds up the temperature synchronization process and greatly shortens the evaporation time of the condensed water on the spinning frame roller.

[0004] However, in this scheme, the pressing strip cannot effectively fix and limit the spinning frame rollers in the placing rack. When the placing rack is pushed to the workshop by the moving frame to replace the spinning frame rollers, the spinning frame rollers will shake up and down in the grooves if the road is bumpy. If the amplitude is large, the position of the steel roller and the outer leather of the spinning frame roller will be damaged, causing economic losses to the enterprise. SUMMARY

[0029] Please refer to Figures 1-12The embodiment of the application discloses a spinning frame roller placing device, which comprises a trolley 1, a storage cabinet 2 is fixedly arranged on the trolley 1, a plurality of storage racks 3 are arranged in the storage cabinet 2, a moving groove 31 is formed in the storage rack 3, a moving block 4 is slidably arranged in the moving groove 31, a storage groove 41 is formed in the center of the moving block 4, a first storage rack 5 and a second storage rack 6 are arranged in the storage groove 41, a plurality of sliding grooves 32 are formed in the storage rack 3, a limiting block 7 matched with the sliding groove 32 is fixedly connected to the moving block 4, a first spring 8 is fixedly connected between the limiting block 7 and the bottom of the sliding groove 32, a limiting groove 42 is formed in one side of the moving block 4, and a positioning assembly 9 is arranged on the storage rack 3 and is in transmission connection with the limiting groove 42. Before the roller is placed, the first spring 8 is in a normal extension state, the limiting block 7 is lifted and abuts against the top of the sliding groove 32, at this time, the height of the moving block 4 exceeds the height of the top of the storage rack 3, at this time, the roller is placed in the first storage rack 5 and the second storage rack 6 arranged in the storage groove 41, the steel roller in the middle of the roller is placed in the first storage rack 5, and the leather wrapped parts at the two ends of the steel roller are placed in the second storage rack 6, due to the weight of the roller, the moving block 4 is driven to move downwards along the moving groove 31 and compresses the first spring 8, when the moving block 4 moves to the position that the limiting groove 42 is in contact with the positioning assembly 9, the positioning assembly 9 is clamped with the limiting groove 42, so that the moving block 4 cannot rise or fall in the moving groove 31, the stability of the moving block 4 is improved, in addition, when the limiting groove 42 is clamped with the positioning assembly 9, the moving block 4 does not reach the bottom of the moving groove 31, the size of the limiting groove 42 is slightly larger than the size of the component in the positioning assembly 9 which is clamped with the limiting groove 42, that is, the positioning assembly 9 can slightly move in the limiting groove 42 and does not affect the positioning effect of the positioning assembly 9 on the moving block 4, when the trolley 1 is used to push the storage cabinet 2 to the workshop to replace the roller, when the trolley 1 encounters a bumpy road section, the first spring 8 can buffer the vibration of the moving block 4, the stability of the roller placed in the moving block 4 is ensured, and the roller is protected.

[0030] Reference Figures 5-7As shown in the drawings, in the embodiment, preferably, the positioning assembly 9 comprises a positioning rod 91, the storage rack 3 is provided with a positioning slot 33, the positioning rod 91 is rotationally connected with the positioning slot 33, and the bottom of the positioning rod 91 and the positioning slot 33 are fixedly connected with a second spring 92. A part of the positioning rod 91 is located in the positioning slot 33, and another part is located outside the storage rack 3. When the roller is placed in the moving block 4, the moving block 4 is driven to move downwards along the moving slot 31. During the downward movement of the moving block 4, the bottom plate of the moving block 4 abuts against the positioning rod 91, thereby compressing the second spring 92, until the limiting slot 42 on the moving block 4 reaches the position of the positioning rod 91. The positioning rod 91 loses the abutment of the moving block 4, and the second spring 92 restores the state, thereby pushing the positioning rod 91 on one side to move downwards and form a clamping connection with the limiting slot 42. At this time, the moving block 4 is limited in the moving slot 31 and cannot continue to move upwards and downwards. At this time, the part of the positioning rod 91 located in the positioning slot 33 is upwardly tilted, and therefore the part of the positioning rod 91 located outside the storage rack 3 is downwardly deflected. When the roller needs to be taken out, the part of the positioning rod 91 located outside the storage rack 3 is lifted upwards, the positioning rod 91 located on one side of the positioning slot 33 is downwardly deflected, thereby releasing the clamping connection with the limiting slot 42. At this time, the first spring 8 moves upwards, thereby driving the moving block 4 to move upwards along the moving slot 31, so as to facilitate the staff to take out the roller.

[0031] Referring to Figure 6 and Figure 12 As shown in the drawings, in the embodiment, preferably, the storage rack 3 is axially symmetrically provided with a plurality of lifting slots 34 on both sides, one side of the lifting slot 34 is provided with a first rack 10, both sides of the moving block 4 are axially symmetrically provided with a clamping assembly 11, and the clamping assembly 11 is drivingly connected with the first rack 10. When the roller is placed in the moving block 4, the moving block 4 is driven to move downwards, the movement of the moving block 4 drives the clamping assembly 11 to move downwards, thereby meshing and driving the first rack 10 in the lifting slot 34. The clamping assembly 11 works to clamp and limit the steel roller part in the middle of the roller placed on the first storage rack 5, thereby further ensuring the stability of the roller placed in the storage rack 3.

[0032] Referring to Figure 8As shown, in this embodiment, preferably, the clamping assembly 11 comprises a first gear 111, a rotating rod 112 is fixedly arranged through the center of the first gear 111, one end of the rotating rod 112 away from the first gear 111 is movably arranged through one side of the storage rack 3, the moving block 4 is provided with a clamping groove 43, a clamping rod 113 is movably arranged in the clamping groove 43, and the clamping rod 113 is threadedly connected with the rotating rod 112; the moving block 4 is moved downward along the moving groove 31 to drive the first gear 111 to move downward to engage and drive the first gear rack 10 in the lifting groove 34, the first gear 111 is rotated, the rotation of the first gear 111 drives the rotating rod 112 to rotate, and since the rotating rod 112 and the clamping rod 113 are threadedly connected, the rotation of the rotating rod 112 drives the clamping rod 113 to move along the clamping groove 43 to the direction close to the leather roller until the clamping rods 113 on both sides clamp and limit the middle part of the leather roller, the clamping groove 43 can prevent the clamping rod 113 from rotating with the rotating rod 112, and through the step, the moving block 4 can be limited and fixed during the downward movement, and the stability of the leather roller is guaranteed.

[0033] Referring to Figures 9-11 As shown, in this embodiment, preferably, the second storage rack 6 is movably provided with a placement plate 12, the placement plate 12 is provided with an arc-shaped groove 121, and an arc-shaped plate 13 is slidably connected in the arc-shaped groove 121; the middle steel roller part of the leather roller is placed on the first storage rack 5, the leather wrapped parts on both sides of the leather roller are directly contacted with the gauze in actual production, and it is necessary to guarantee the cleanliness and non-damage of the leather part of the leather roller, a layer of soft wiping pad can be arranged on the contact surface between the placement plate 12 on the second storage rack 6 and the leather roller, when the leather roller is cleaned, the wiping pad can be wiped and cleaned on the surface of the leather roller by rotating the placement plate 12, the cleanliness is guaranteed, and the arc-shaped plate 13 can be rotated in the arc-shaped groove 121, the leather roller can be wrapped when the arc-shaped plate 13 is rotated above the placement plate 12, and a layer of wiping pad can also be arranged on the inner side of the arc-shaped plate 13, which can clean the surface of the leather roller and protect the side of the leather roller during rotation.

[0034] Referring to Figure 5 and Figure 12As shown, in the embodiment, preferably, the storage rack 3 is provided with a sliding groove 35 on both sides, the second rack 14 is arranged in the sliding groove 35, the rotating assembly 15 is arranged on both sides of the moving block 4 in axial symmetry, and the rotating assembly 15 is in transmission connection with the second rack 14 and the arc-shaped plate 13. The moving block 4 drives the rotating assembly 15 to mesh with the second rack 14 arranged in the sliding groove 35 during the descending process, thereby driving the rotating assembly 15 to work. The working of the rotating assembly 15 can make the arc-shaped plate 13 rotate in the arc-shaped groove 121 to the upper side of the placing plate 12, which can clean the surface of the leather roller and also can limit and protect the leather roller on one side.

[0035] Referring to Figure 10As shown, in the embodiment, preferably, the rotating assembly 15 comprises a second gear 151, a fixed plate 16 is fixedly arranged in the storage rack 3, a rotating cylinder 152 is fixedly arranged at the center of the second gear 151 and penetrates through the second gear 151, the rotating cylinder 152 is movably arranged at one end away from the second gear 151 and penetrates through the storage rack 3 and the fixed plate 16 and is fixedly connected with a deflection rod 153, and the deflection rod 153 is fixedly connected with the arc-shaped plate 13. The movement of the moving block 4 drives the second gear 151 to move downward to engage and drive the second gear rack 14 arranged in the chute 35, the second gear 151 rotates accordingly, the rotation of the second gear 151 drives the rotating cylinder 152 to rotate, the rotation of the rotating cylinder 152 drives the deflection rod 153 to rotate to drive the arc-shaped plate 13 to rotate in the arc-shaped groove 121. When the arc-shaped plate 13 rotates to above the placement plate 12 and one end of the arc-shaped plate 13 abuts against the movement of the placement plate 12, at this time, the moving block 4 is continuously moved downward, the deflection rod 153 is continuously rotated, and the arc-shaped plate 13 drives the placement plate 12 to rotate a circle together, so that the placement plate 12 and the arc-shaped plate 13 can be cleaned by the wiping pad arranged on the surface of the placement plate 12 and the arc-shaped plate 13. In this process, the middle part of the leather roller has been limited by the clamping rod 113, so that the rotation of the arc-shaped plate 13 and the placement plate 12 will not affect the placement state of the leather roller and the leather roller is fixedly and stably arranged to facilitate the rotation of the arc-shaped plate 13 and the placement plate 12 to clean the surface of the leather roller. After one rotation, the placement plate 12 returns to the original position, the arc-shaped plate 13 is above the placement plate 12, and the arc-shaped plate 13 and the placement plate 12 form a circle to wrap the leather roller. The arc-shaped plate 13 and the placement plate 12 wrapping the leather roller have another advantage: when the leather roller needs to be taken out, the first spring 8 can instantly pop up the moving block 4 upward, the moving block 4 is popped up upward in the process, the leather roller placed in the moving block 4 is also popped up upward and then falls back to the storage rack. In this process, the leather roller can be damaged, the clamping rod 113 limits the middle position of the leather roller at this time to avoid this phenomenon, but if the clamping rod 113 is damaged and the clamping of the leather roller is unstable, the arc-shaped plate 13 can also block the upward pop-up force of the leather roller, which can only pop up to a limited height, and the wiping pad arranged on the inner side of the arc-shaped plate 13 can also reduce the impact force caused by the pop-up of the leather roller to protect the leather roller.

[0036] Referring to Figures 9-11As shown, in this embodiment, preferably, one side of the placement plate 12 is fixedly connected with a connecting barrel 17, one end of the connecting barrel 17 away from the deflection rod 153 is fixedly connected with a sleeve 18, the sleeve 18 movably sheaths outside the rotating barrel 152, and one end of the sleeve 18 away from the connecting barrel 17 is rotatably connected with the fixed plate 16; since the shape of the placement plate 12 is semicircular, the placement plate 12 will be in a state of suspension for an instant during the rotation of the arc-shaped plate 13, and it is impossible to ensure that the placement plate 12 can rotate in one rotating track after continuous rotation. By sheathing a sleeve 18 outside the rotating barrel 152, the rotating barrel 152 drives the arc-shaped plate 13 to rotate, thereby driving the placement plate 12 to rotate, and the rotation of the placement plate 12 drives the connecting barrel 17 to rotate, thereby driving the sleeve 18 to rotate, so that the position of the placement plate 12 during rotation can be limited and kept in one track for rotation, the surface of the roll can be better cleaned, and the fixed plate 16 provides a supporting effect.

[0037] Referring to Figure 12 As shown, in this embodiment, preferably, the height of the second rack 14 in the storage rack 3 is lower than the height of the first rack 10; when the roll is to be stored, the moving block 4 moves downward, the clamping assembly 11 first drives the first rack 10, so that the clamping rod 113 limits and fixes the middle position of the roll, then the moving block 4 continuously descends, the rotating assembly 15 drives the second rack 14, so that the arc-shaped plate 13 and the placement plate 12 rotate, thereby cleaning the surface of the roll, and this sequence can ensure the stability of the roll during cleaning. Similarly, when the roll is to be taken out, the moving block 4 moves upward, the roll is first cleaned, and then the roll is released from the limiting and fixing, so that the stability of the roll can be ensured during storage and taking out of the roll, and the roll is not damaged.

[0038] The working principle of the present application is that before placing the roller, the first spring 8 is in a normal extension state, the limiting block 7 is lifted and abuts against the top of the sliding groove 32, at this time, the moving block 4 exceeds the height of the storage rack 3, at this time, the roller is placed in the first storage rack 5 and the second storage rack 6 arranged in the storage groove 41, the steel roller in the middle of the roller is placed in the first storage rack 5, and the leather wrapped part at both ends of the steel roller is placed in the second storage rack 6, due to the weight of the roller itself, the moving block 4 is driven to move downward along the moving groove 31 and compress the first spring 8, in the process of moving downward, the bottom plate of the moving block 4 abuts against the positioning rod 91 and compresses the second spring 92, until the limiting groove 42 on the moving block 4 reaches the position of the positioning rod 91, the positioning rod 91 loses the abutment of the moving block 4, in the recovery state of the second spring 92, the positioning rod 91 on one side is lifted downward and forms a clamping connection with the limiting groove 42, at this time, the moving block 4 is limited in the moving groove 31 and cannot continue to move up and down, at this time, the part of the positioning rod 91 located in the positioning groove 33 is upwardly tilted, so the part of the positioning rod 91 located outside the storage rack 3 is downwardly deflected, when the roller needs to be taken out, the part of the positioning rod 91 located outside the storage rack 3 is lifted upward, the part of the positioning rod 91 located in one side of the positioning groove 33 is downwardly deflected and thus the clamping connection with the limiting groove 42 is released, at this time, the first spring 8 moves upward and drives the moving block 4 to move upward along the moving groove 31, so as to facilitate the worker to take out the roller, at the same time, the moving block 4 moves downward along the moving groove 31 and drives the first gear 111 to move downward and thus meshes with the first rack 10 in the lifting groove 34, the first gear 111 rotates, the rotation of the first gear 111 drives the rotating rod 112 to rotate, since the rotating rod 112 and the clamping rod 113 are threadedly connected, the rotation of the rotating rod 112 drives the clamping rod 113 to move along the clamping groove 43 to the direction close to the roller until the clamping rod 113 on both sides clamps and limits the middle part of the roller, then, the moving block 4 continuously descends and drives the second gear 151 to move downward and thus meshes with the second rack 14 arranged in the sliding groove 35, the second gear 151 rotates, the rotation of the second gear 151 drives the rotating cylinder 152 to rotate, the rotation of the rotating cylinder 152 drives the deflection rod 153 to rotate and thus drives the arc-shaped plate 13 to rotate in the arc-shaped groove 121, when the arc-shaped plate 13 rotates to the upper side of the placing plate 12 and one end of the arc-shaped plate 13 abuts against the moving of the placing plate 12, at this time, the moving block 4 continuously moves downward, the deflection rod 153 continuously rotates, the arc-shaped plate 13 drives the placing plate 12 to rotate a circle, so that the wiping pad arranged on the surface of the placing plate 12 and the arc-shaped plate 13 can clean the surface of the roller, in this process, the middle part of the roller has been limited by the clamping rod 113, so the rotation of the arc-shaped plate 13 and the placing plate 12 will not affect the placing state of the roller and the rotation of the arc-shaped plate 13 and the placing plate 12 can clean the surface of the roller.
