Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile equipment, and particularly relates to a cloth dustproof compression box. BACKGROUND

[0002] In the production and processing process of a textile mill, cloth is cut, and the cut-off waste cloth has large gaps when stacked, so it occupies a large space. If the waste cloth is placed on the ground or in a collection basket, it is easy to be contaminated with a lot of dust, which brings inconvenience to the later processing.

[0003] In the prior art, an application with the patent number CN202111028943.1 proposes a waste compression dustproof turnover box in a non-woven fabric production process, which comprises a turnover box body, a driving assembly, a first opening and closing assembly, and a second opening and closing assembly. The turnover box body is provided as a hollow cavity with an opening at the top. The driving assembly is arranged on the outer side wall of the turnover box body. The first opening and closing assembly and the second opening and closing assembly are arranged inside the turnover box body. The first opening and closing assembly and the second opening and closing assembly are symmetrically arranged about the middle part of the driving assembly. The waste compression dustproof turnover box in the non-woven fabric production process in the application has the following technical problems in the use process:

[0004] When cloth is put into the turnover box body, the cover plate needs to be opened. When the cover plate is completely opened, the compression plate is in a horizontal state. After the cloth is put in, it falls on the compression plate. Then the cover plate needs to be closed. The first opening and closing assembly and the second opening and closing assembly drive the compression plate to move close to the left or right side wall of the turnover box body, so that the cloth on the compression plate falls into the turnover box body. When a large amount of cloth is put in, it cannot be put into the turnover box body at one time, and multiple cover plate opening and closing operations are required. Moreover, after the cloth falls into the turnover box body, the cover plate needs to be opened and closed again to drive the compression plate to compress the cloth, which is complicated to operate.

[0005] When the compression plate compresses the cloth, the compression plate is in a horizontal state and the cover plate is in an open state. After the compression step, the cover plate needs to be closed, and the compression plate moves to both sides of the turnover box body. During the movement of the compression plate, the cloth close to the lower part of the compression plate is easily lifted, so that the cloth is clamped between the compression plate and the inner wall of the turnover box body, affecting the movement trajectory of the compression plate when the opening and closing assembly works normally.

[0006] (3) When the turnover box cover plate and the connecting rod fail, since the cover plate is fixedly connected with the connecting rod mechanism, the cover plate cannot be opened alone for maintenance, which is inconvenient. SUMMARY

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0042] like Figures 1-7 As shown, a fabric dustproof compression box includes a rectangular box 1. The box 1 has a front side wall 14, a rear side wall 15, a left side wall 16, a right side wall 17, and a bottom wall 18. The tops of the left side wall 16 and the right side wall 17 of the box 1 are respectively hinged to a top cover 12. When the top cover 12 is opened, the fabric is put into the box 1. The bottom of the front side wall 14 of the box 1 is hinged to a front door 13. The front door 13 is convenient to open when the box 1 is full of fabric, so that the fabric can be taken out.

[0043] In this embodiment, a partition 11 is provided inside the box 1 near the rear side wall 15. The partition 11 is arranged parallel to the rear side wall 15, and a partition layer is formed between the partition 11 and the rear side wall 15.

[0044] The box 1 is equipped with a lifting mechanism, a linkage mechanism and a cover opening mechanism. The lifting mechanism includes a motor 3 fixedly installed on the bottom wall 18. The motor 3 is located in the partition and will not interfere with the fabric inside the box 1. The structure is reasonably designed. The output shaft of the motor 3 is connected to a screw 31. The screw 31 is threadedly connected to a push-pull rod 32. The push-pull rod 32 can be moved up and down by rotating the screw 31.

[0045] The linkage mechanism includes sliding plates 2 respectively slidably mounted on the left side wall 16 and the right side wall 17. The sliding plates 2 are connected to a push-pull rod 32. Crossbars 22 are fixedly connected to the upper ends of both sliding plates 2. The crossbars 22 are hinged to a first connecting rod 23, which in turn is hinged to a second connecting rod 24. The second connecting rod 24 is hinged to a pressure rod 25. A pressure plate 251 is connected to the bottom of the pressure rod 25. A fixing rod 26 is located near the bottom of the sliding plates 2, and this fixing rod 26 is hinged to the pressure rod 25. By setting up the linkage mechanism, the pressure plate 251 can compress the fabric to the bottom of the housing 1 in one go, and the pressure plate 251 is less likely to lift the fabric from inside the housing 1 during its movement, thus preventing the fabric from interfering with the movement trajectory of the linkage mechanism.

[0046] The opening mechanism includes a top rod 21 fixedly mounted on the top of the slide plate 2, and a pulley 211 is provided on the top of the top rod 21. The pulley 211 abuts against the upper cover 12 to form rolling friction, which has low friction and is conducive to the flexible opening and closing of the cover.

[0047] The lifting mechanism, the connecting rod mechanism and the cover opening mechanism are arranged in the box body 1. The motor 3 of the lifting mechanism operates to control the lifting movement of the push-pull rod 32 through the screw rod 31, thereby driving the sliding plate 2 to move up and down, so that the connecting rod mechanism controls the compression of the pressing plate 251. In use, the upper cover 12 is in a closed state. First, the motor 3 is controlled to operate to make the push-pull rod 32 move up, thereby driving the sliding plate 2 and the connecting rod mechanism connected with the sliding plate 2 to move up, and the connecting rod mechanism drives the pressing plate 251 to open. When the sliding plate 2 continues to rise, the top rod 21 pushes the upper cover 12 to open the upper cover 12. At this time, the cloth can be put into the box body 1, and the cloth directly falls into the bottom of the box body 1. When the cloth is put in, the motor 3 is controlled to operate to drive the push-pull rod 32 to move down, thereby driving the sliding plate 2, the top rod 21 connected with the sliding plate 2 and the connecting rod mechanism to move down. The top rod 21 moves down to facilitate the closing of the upper cover 12. The connecting rod mechanism moves down to drive the pressing plate 251 to close, thereby compressing the cloth at the bottom of the box body 1. The operation process is smooth and convenient. Specifically, two horizontal rods 22 are arranged on each of the two sliding plates 2. The two horizontal rods 22 on the same sliding plate 2 are arranged close to the two sides of the sliding plate 2 respectively. One horizontal rod 22 is connected with a first connecting rod 23 through a first hinge shaft. The first connecting rod 23 is connected with a second connecting rod 24 through a second hinge shaft. The second connecting rod 24 is connected with a pressing rod 25 through a third hinge shaft. The two pressing rods 25 close to the left side wall 16 are connected with a pressing plate 251. The two pressing rods 25 close to the right side wall 17 are connected with a pressing plate 251.

[0048] The first stabilizing rod 241 is connected between the two second hinge shafts arranged on one side in the box body 1. The second stabilizing rod 242 is connected between the two third hinge shafts arranged on one side in the box body 1. The first stabilizing rod 241 and the second stabilizing rod 242 increase the stability of the connecting rod structure, so that the transmission is stable.

[0049] The support plates 4 are fixedly arranged on the top inner walls of the left side wall 16 and the right side wall 17. The two support plates 4 are connected with the push plates 41 respectively. The push plates 41 and the left side wall 16 form a sandwich structure, and the push plates 41 and the right side wall 17 form a sandwich structure. The positions of the push plates 41 correspond to the positions of the first connecting rods 23.

[0050] The support plates 4 are longer than the horizontal rods 22, and the lengths of the support plates 4 are less than the total length of the horizontal rods 22 and the first connecting rods 23 in the horizontal state. The first connecting rods 23 can be accommodated in the sandwich structure in the vertical state, and the first connecting rods 23 can be moved out of the sandwich structure and drive the pressing rods 25 to move in the horizontal state.

[0051] The first stabilizing rod 241 is connected with the sliding plate 2 through a telescopic rod 27, one end of the telescopic rod 27 is rotatably sleeved on the first stabilizing rod 241, the other end of the telescopic rod 27 is hingedly connected with the sliding plate 2, the telescopic rod 27 is externally sleeved with a compression spring 271, one end of the compression spring 271 abuts against the first stabilizing rod 241.

[0052] The pressing rod 25 is L-shaped, the bending part of the pressing rod 25 is hingedly connected with the fixing rod 26, the long end of the pressing rod 25 is connected with a pressing plate 251, and the short end of the pressing rod 25 is hingedly connected with the second connecting rod 24. The thickness of the long end of the pressing rod 25 gradually decreases from the bending part to the end. When the first connecting rod 23 is in a horizontal state, the upper surface of the long end of the pressing rod 25 is parallel to the bottom wall 18, and the plane where the lower surface of the long end of the pressing rod 25 is located and the plane where the bottom wall 18 is located form an included angle of 5°-15°. Since the cloth is mostly put into the box 1 at the middle position of the box 1, the cloth at the middle position is thicker than that at the two sides, and therefore the existing inclination angle of the pressing plate 251 is more suitable for the compression of the cloth with different thicknesses at different positions in the box 1.

[0053] When the upper cover 12 is opened, the horizontal rod 22 and the first connecting rod 23 are located in the interlayer, and under the elastic force of the compression spring 271, the end of the first connecting rod 23 and the second connecting rod 24 connected with each other abuts against the push plate 41, and the first connecting rod 23 is retracted in the interlayer. During the closing process of the upper cover 12, the first connecting rod 23 moves downward, and when the bottom end of the first connecting rod 23 moves out of the bottom end of the push plate 41, under the elastic force of the compression spring 271, the hingedly connected end of the first connecting rod 23 and the second connecting rod 24 moves away from the left side wall 16 or the right side wall 17, and at the same time, the short end of the pressing rod 25 moves upward, and the long end of the pressing rod 25 moves downward to drive the pressing plate 251 to close, thereby completing the compression action.

[0054] The box 1 is provided with vertically arranged slide rails 33 near the left side wall 16 and the right side wall 17, respectively, the slide rails 33 are slidably provided with slide sleeves 34, the slide sleeves 34 are fixedly connected with the sliding plate 2, the slide rails 33 are slidably matched with the sliding plate 2 through the slide sleeves 34, and the slide sleeves 34 can slide up and down on the slide rails 33. The slide sleeves 34 and the slide rails 33 make the sliding plate 2 slide up and down more stably.

[0055] The partition plate 11 is connected with the left side wall 16 and the right side wall 17 at both sides, so that the cloth cannot enter the interlayer, and the partition plate 11 is provided with an open slot at the corresponding position of the sliding plate 2. One side of the sliding plate 2 near the bottom is connected with the push-pull rod 32 through a connecting rod, and the connecting rod is located in the open slot, so that the push-pull rod 32 drives the sliding plate 2 to move up and down.

[0056] The working process of the present application is: the initial state of the cloth dustproof compression box is that the upper cover 12 is closed, when it is needed to open the compression box to put in the cloth, the motor 3 is started to reverse, the screw rod 31 rotates to drive the push-pull rod 32 to move upwards, the push-pull rod 32 drives the sliding plate 2 to move upwards, the sliding plate 2 drives the cross rod 22 to move upwards, the cross rod 22 drives the first connecting rod 23 to move upwards, when the first connecting rod 23 collides with the push plate 41, the push plate 41 hinders the first connecting rod 23 from continuing to move horizontally upwards, so that the first connecting rod 23 and the second connecting rod 24 are hinged to move towards the left side wall 16 or the right side wall 17, so that the first connecting rod 23 is retracted into the interlayer of the push plate 41, the first connecting rod 23 changes from a horizontal state to a vertical state, and the downward thrust of the first connecting rod 23 to the second connecting rod 24 makes the second connecting rod 24 press the short end of the pressing plate 251 from a vertical state to a horizontal state, at this time the long end of the pressing plate 251 changes from a horizontal state to a vertical state; the sliding plate 2 continues to move upwards, the pulley 211 on the top of the sliding plate 2 passes through the through hole on the support plate 4 to lift the upper cover 12, the upper cover 12 is opened, and the cloth is put into the dustproof compression box; when the cloth is put into the box body 1, the pressing plate 251 is in a vertical position and close to the left side wall 16 or the right side wall 17, the cloth directly falls into the bottom of the box body 1 and does not press above the pressing plate 251, so that the connecting rod mechanism can be protected from being pressed and deformed, and it is especially suitable for the case that a large amount of cloth is put in at one time.

[0057] When the upper cover 12 is opened and the cloth is put into the dustproof compression box, the motor 3 is started to rotate in the positive direction, the screw rod 31 rotates to drive the push-pull rod 32 to move downwards, the push-pull rod 32 is connected with the sliding plate 2 through the opening slot on the partition plate 11, and drives the sliding plate 2 to move downwards on the sliding rail 33 through the sliding sleeve 34, in the moving process, the sliding plate 2 drives the first connecting rod 23 and the fixed rod 26 to move downwards at the same time, the fixed rod 26 drives the pressing rod 25 to move downwards, when the first connecting rod 23 moves below the push plate 41, the first connecting rod 23 is driven out of the interlayer by the stretching spring 271 and the telescopic rod 27, the first connecting rod 23 is driven out of the interlayer, because the second connecting rod 24 is hinged with the pressing rod 25 and the first connecting rod 23, so that the second connecting rod 24 swings with the movement of the pressing rod 25 and the first connecting rod 23, the second connecting rod 24 drives the long end of the pressing plate 251 to change from a vertical state to an inclined position, and the short end of the pressing plate 251 changes from a horizontal state to a vertical state. Figure 5 Changes to Figure 6 The state; the hinged part of the pressing rod 25 and the second connecting rod 24 is pulled upwards by the second connecting rod 24, and the bent part in the middle of the pressing rod 25 is fixed by the fixed rod 26, so that the long end of the pressing plate 251 changes from a vertical state to an inclined position; in the process of moving downwards, the top rod 21 and the pulley 211 on the top of the sliding plate 2 also move downwards at the same time, so that the upper cover 12 slowly falls down and closes under the joint action of gravity and the pulling force of the stretching spring 42.

[0058] When the upper cover 12 is just closed, the motor 3 continues to rotate forward, the slide plate 2 continues to move downward, the first connecting rod 23 is completely removed from the interlayer, the first connecting rod 23 is converted to a horizontal position, the long end of the pressing rod 25 is converted to a horizontal position, the slide plate 2 continues to move downward until the pressing plate 251 compresses the cloth, and Figure 6 Changes to Figure 7 When the cloth in the box 1 is full, the front door 13 is opened, and the cloth is taken out.

[0059] The present application is characterized in that the connecting rod mechanism, the lifting mechanism and the cover opening mechanism are arranged in the box 1, so that the operation of putting in and compressing the cloth is convenient and simple, the cloth is compressed to the bottom of the box 1 at one time, the dustproof and compression effect of the dustproof compression box for cloth is better, and the practicality is stronger.

[0060] The specific embodiments of the present application described above do not constitute a limitation on the scope of protection of the present application. Any various other corresponding changes and modifications made according to the technical concept of the present application shall be included in the scope of protection of the claims of the present application.

The first link is hinged to the second link. The second link is hinged to the pressure rod. The bottom of the pressure rod is connected to the pressure plate. The sliding plate is provided with a fixed rod near the bottom. The fixed rod is hinged to the pressure rod. The opening mechanism includes a top rod fixedly mounted on the top of the slide plate; Support plates are fixedly provided on the top inner wall of the left side wall and the top inner wall of the right side wall. The two support plates are respectively connected to push plates. A sandwich is formed between one push plate and the left side wall and between the other push plate and the right side wall. The position of the push plate corresponds to the position of the first connecting rod. When the compression box needs to be opened to feed the fabric, the motor is started and reversed. The crossbar drives the first connecting rod to move upward. When the first connecting rod touches the push plate, the push plate prevents the first connecting rod from moving horizontally upward. Then, the hinge of the first connecting rod and the second connecting rod will move towards the left or right side wall. Therefore, the first connecting rod is retracted into the interlayer of the push plate. The first connecting rod changes from a horizontal state to a vertical state. The slide plate continues to move upward. When the fabric is fed into the box, the pressure plate is in a vertical position and close to the left or right side wall. The fabric falls directly into the bottom of the box. When the top cover is opened and the fabric is put into the dustproof compression box, the motor is started to rotate forward. When the first connecting rod moves to the bottom of the push plate, the first connecting rod moves out of the interlayer, and the pressure plate changes from a vertical position to an inclined position. When the top cover is just closed, the motor continues to rotate forward, the slide plate continues to move downward, the first connecting rod moves completely out of the interlayer, the first connecting rod changes to a horizontal position, and the pressure plate changes to a horizontal position.
