Abstract
Description
Technical Field
[0001] This invention relates to the field of tobacco logistics equipment technology, and in particular to a turnover box clamping device. Background Technology
[0002] In tobacco processing workshops, large turnover boxes are used to transfer tobacco bales between the vacuum rehumidification and loose rehumidification processes. These boxes are large and heavy, and are repeatedly used under high pressure and humidity, making their inner and outer surfaces prone to accumulating tobacco residue and condensation, requiring regular cleaning. Currently, cleaning operations generally use manual clamping: 5-6 operators work together to push the turnover box into the turning station, then manually lock it using fixed hooks or simple clamps. This solution has the following drawbacks: 1. The clamping force is determined by manual experience, leading to uneven force application. During turning, the box is prone to slipping, shaking, or even falling, affecting cleaning quality and creating safety hazards; 2. The clamping and releasing actions are time-consuming and require multiple operators, which is incompatible with the automated cleaning cycle, becoming a bottleneck for the entire cleaning line; 3. Existing clamps have a fixed structure and non-adjustable opening size, making them unsuitable for slightly deformed or different sized turnover boxes, requiring frequent replacement of auxiliary tools, increasing downtime and spare parts costs.
[0003] In conclusion, developing a clamping device that can automatically clamp, provide stable cleaning results, and reduce labor costs is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation
[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This invention provides a turnover box clamping device; please refer to the attached instruction manual. Figure 1 and 2This application includes a horizontally arranged first support plate 11, with a first drive screw 12 provided on the upper surface of the first support plate 11. The first drive screw 12 is arranged along the length direction of the first support plate 11, and a second support plate 21 is slidably connected to the first drive screw 12. The first support plate 11 and the second support plate 21 are arranged parallel to each other. A second drive screw 22 is slidably connected to the second support plate 21, and similarly, the second drive screw 22 is arranged along the length direction of the second support plate 21. Preferably, the sliding direction of the first support plate 11 is the same as that of the first drive screw. The sliding direction of the second bearing plate 21 is the same as the axial direction of the second drive screw 22, and the first drive screw 12 is perpendicular to the second drive screw 22. Furthermore, a support plate 31 is vertically provided on the second bearing plate 21, and a mounting seat 35 is slidably provided on the support plate 31. A clamping fixture is rotatably provided on the mounting seat 35. Preferably, the sliding direction of the mounting seat 35 is perpendicular to the end face of the second bearing plate 21, while the rotation axis of the clamping fixture is parallel to the second drive screw 22. The clamping fixture can hold turnover boxes of different sizes. The first support plate 11 provided in this application is slidably connected to the second support plate 21 via the first drive screw 12, enabling the second support plate 21 and its supported components to move longitudinally. The second support plate 21 is slidably connected to the support plate 31 via the second drive screw 22, enabling the support plate 31 and its clamping fixture to move laterally. The clamping fixture can move vertically along the support plate 31. In other words, under the synergistic action of the sliding components, the clamping fixture can move to any position in the cleaning area. When the length or width of the turnover box exceeds the cleaning area, the turnover box area located outside the cleaning area can be transferred to the cleaning area by adjusting the first drive screw 12 or the second drive screw 22. When there are dirt on the turnover box that is difficult to rinse, the setting height of the turnover box can be adjusted to change the water flow impact on the turnover box, ensuring that the turnover box receives a more reliable cleaning effect. Furthermore, the clamping fixture can also drive the turnover box to rotate, ensuring that each side wall of the turnover box can be rinsed evenly.
[0026] Preferably, a number of reinforcing ribs are provided on the end face of the support plate 31 away from the first guide rail 36, and the reinforcing ribs are used to improve the load strength of the support plate 31.
[0027] Please refer to the instruction manual attached. Figure 3A support plate 31 is provided with a first guide rail 36 along its length. A first slider is slidably mounted on the first guide rail 36. A mounting plate 34 is attached to the end face of the first slider away from the first guide rail 36. The first slider and the mounting plate 34 are fixed together by fastening bolts. The mounting plate 34 and the mounting base 35 are also fixed together by fastening bolts. Preferably, the mounting base 35 includes a first plate and a second plate that are perpendicular to each other, and the sides of the first plate and the second plate are connected to each other. The first plate and the mounting plate 34 are attached to each other, so that the entire mounting base 35 can move with the first slider. A rotary cylinder 41 is fixedly connected to the side of the first plate away from the mounting plate 34. The rotating rod of the rotary cylinder 41 extends to the side away from the second plate and passes vertically through the second plate. A connecting plate 42 is provided at the end of the rotating rod that passes through the second plate. Preferably, the connecting plate 42 is a circular plate. The rotating rod and the connecting plate 42 are coaxially arranged. Two limiting grooves 43 are provided on the end face of the connecting plate 42. Each limiting groove 43 is specifically an arc-shaped groove. Each arc-shaped groove is symmetrical about the axis of the connecting plate 42. Correspondingly, two blocks are provided on the side wall of the second plate opposite to the connecting plate 42. Each block extends into the limiting groove 43. In the initial state, each block is located at the opposite end of the limiting groove 43. When the rotating rod drives the connecting plate 42 to rotate, each block slides in the limiting groove 43. Since the arc of each limiting groove 43 is slightly less than 180° and they are not connected to each other, after the connecting plate 42 rotates a certain angle, each block abuts against the opposite end of each limiting groove 43, thereby limiting the rotation angle of the connecting plate 42 and preventing the rotating cylinder 41 from rotating continuously in one direction, thereby exceeding its maximum rotation limit and affecting its service life. Preferably, when the block slides from the beginning to the end of the limiting groove 43, the lower end face of the turnover box is flipped to the upper side to ensure that the turnover box is thoroughly cleaned.
[0028] Furthermore, a connecting seat 44 is fixed on the end face of the connecting plate 42 away from the second plate. A connecting hole is provided on the side wall of the connecting seat 44, through which the connecting seat 44 passes, and the axis of the connecting hole is parallel to the first drive screw 12. Preferably, the clamping clamp includes a clamping cylinder 45, the output shaft of which extends into the connecting hole. A fastening screw is provided on the connecting seat 44, perpendicular to the output shaft of the clamping cylinder 45 and extending into the interior of the output shaft of the clamping cylinder 45, locking the fastening screw to the output shaft of the clamping cylinder 45. Clamping arms 46 are provided on the side wall of 45 and its output shaft respectively. Each clamping arm 46 is located on both sides of the connecting seat 44. When the clamping cylinder 45 extends the output shaft, the position of the output shaft is locked, and the body of the clamping cylinder 45 moves away from the connecting seat 44. The distance between each clamping arm 46 increases, so that the turnover box can be located between each clamping arm 46. Then the output shaft retracts to clamp the turnover box with each clamping arm 46. Since the distance between each clamping arm 46 is adjustable, turnover boxes of different sizes can be placed in the clamping fixture and clamped and fixed, which improves the applicability of this application.
[0029] Please refer to the instruction manual attached. Figure 2 A drive block 33 is provided on the side of the mounting plate 34 away from the mounting base 35. A third drive screw 32 is provided on the support plate 31 along its own length. The third drive screw 32 passes through the drive block 33 and the two are threadedly connected. A lifting cylinder 37 is provided at the upper end of the support plate 31. The output shaft of the lifting cylinder 37 is coaxially arranged with the third drive screw 32. The lifting cylinder 37 is used to drive the third drive screw 32 to rotate axially. The drive block 33 drives the clamping fixture to move axially along the third drive screw 32 to adjust the setting height of the turnover box.
[0030] Preferably, the support plate 31 has ear plates at both ends along its height direction, and ball bearings are provided on the opposite side walls of each ear plate. The two ends of the third drive screw 32 pass through each ball bearing, and each ball bearing is used to assist the rotation of the third drive screw 32.
[0031] Please refer to the instruction manual appendix. Figure 1 and 4The first support plate 11 has fixed seats 13 at both ends along its length. The first drive screw 12 is fixed to each fixed seat 13. The first drive screw 12 is equipped with a first stepping motor 15, which is fixedly connected to the second support plate 21. The first stepping motor 15 is used to drive the second support plate 21 to move. The first drive screw 12 has second guide rails 14 parallel to it on both sides. Each second guide rail 14 is connected to the first support plate 11 through a second slider. Similarly, the second support plate 21 has fixed blocks 23 at both ends along its length. The second drive screw 22 passes through each fixed block 23. The second drive screw 22 is equipped with a second stepping motor 25, which is connected to the support plate 31 through a third support plate. The second drive screw 22 has guide rods 24 parallel to it on both sides. Each guide rod 24 passes through the second stepping motor 25. When the first stepper motor 15 and the second stepper motor 25 are running, the threaded bushings inside them rotate relative to the first drive screw 12 and the second drive screw 22. Since the positions of the first drive screw 12 and the second drive screw 22 are locked, the first stepper motor 15 and the second stepper motor 25 move. The operator can adjust the setting position of the turnover box according to the size of the turnover box to be cleaned by using the first stepper motor 15 and the second stepper motor 25.
[0032] Preferably, the first bearing plate 11 is provided with four pulleys 5 on the side opposite to the first drive screw 12, and the pulleys 5 facilitate the operator to move the turnover box clamping device.
