Description

TECHNICAL FIELD

[0001] The utility model relates to material turnover technical field, concretely is a kind of turnover mechanism for pulp bag. BACKGROUND

[0002] In the field of industrial production and logistics processing, the processing and packaging skin removal of pulp bag is a common process. The traditional pulp bag turnover operation usually relies on manual or simple mechanical equipment to complete, which not only is inefficient, but also has great safety hazards. Especially when the bottom surface of the pulp bag needs to be turned over to the top surface for removing the packaging skin, manual operation often cannot guarantee the stability of the pulp bag, which can easily cause the pulp bag to shift or even fall during the turnover process, thereby affecting the production efficiency and product quality. In addition, the existing turnover equipment mostly adopts a single fixed structure, which lacks flexibility when facing pulp bags of different sizes, and cannot achieve accurate clamping and stable turnover, further limiting its application range.

[0003] In the prior art, although some turnover mechanisms achieve the functions of preliminary clamping and turnover of pulp bags through conveying assemblies, these devices still have many deficiencies in actual application. For example, the spacing adjustment between conveying assemblies is usually not accurate enough to reliably clamp and fix the pulp bag, resulting in position deviation of the pulp bag during the turnover process. At the same time, the overall structure of the turnover mechanism is complex, with high installation and maintenance costs, and it is difficult to adapt to different height working environments.

[0004] To solve the above problems, a turnover mechanism for pulp bag is proposed. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of turnover mechanism for pulp bag, solve the problems such as unstable clamping, low turnover efficiency and poor adaptability of existing pulp bag turnover mechanism in the background art during processing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a kind of turnover mechanism for pulp bag, including two side plates, conveying assembly, auxiliary U-shaped shell, drive mechanism, U-shaped connecting piece, support frame and chassis. The conveying assembly with top and bottom between the two side plates is used for conveying pulp bag. The conveying assembly can realize relative movement through drive mechanism and auxiliary U-shaped shell, so as to realize the clamping and fixing of pulp bag. Further, the front and rear sides of each side plate adjacent to the conveying assembly are fixed with auxiliary U-shaped shell, and four auxiliary U-shaped shells are fixed with slide rod, and each slide block is slidably connected to the top and bottom of the outer diameter of slide rod. One side of the slide block is slidably connected with the auxiliary U-shaped shell, and the other side is fixedly connected with the conveying assembly of top and bottom respectively, to ensure the stability of the conveying assembly during sliding.

[0007] Particularly, the middle of the side plate adjacent to the surface of the conveying assembly is provided with a driving mechanism for adjusting the distance between the two conveying assemblies. The driving mechanism includes a U-shaped driving housing, a positive and negative toothed lead screw, a small motor and a driving block. The positive and negative toothed lead screw is rotatably connected inside the U-shaped driving housing, and the positive and negative teeth of the positive and negative toothed lead screw are respectively threadedly connected with two driving blocks. One side of the driving block is slidably connected with the U-shaped driving housing, and the other side is respectively fixedly connected with the two conveying assemblies. The small motor is fixed at the bottom of the U-shaped driving housing, and its output end penetrates the U-shaped driving housing and is fixedly connected with the positive and negative toothed lead screw. When the small motor is started, the positive and negative toothed lead screw rotates, driving the two driving blocks to move along the positive and negative toothed lead screw, and in turn pushing the two conveying assemblies to relatively approach or move away, so as to realize the clamping and fixing of the pulp bag.

[0008] Among them, the rear side of the two side plates is provided with two U-shaped connectors, one side of each U-shaped connector is fixed with a baffle, and the end is fixed with an L-shaped mounting piece. Four L-shaped mounting pieces are detachably connected with the two side plates through mounting bolts. The design of the U-shaped connector and the L-shaped mounting piece facilitates the assembly and maintenance of the device, and improves the overall rigidity of the device.

[0009] Further, the opposite surfaces of the two side plates are each provided with a support frame for supporting the entire device. A turnover motor is mounted on the top of the left support frame, the output end of the turnover motor is fixed with a rotating rod, and the end of the rotating rod is fixedly connected with the center of the adjacent side plate. When the turnover motor is started, the rotating rod drives the side plate and the conveying assembly thereon to turn 180 degrees, turning the bottom surface of the pulp bag to the top surface, facilitating manual removal of the packaging outer skin. A cushion block is fixed on the top of the right support frame, a connecting rod is rotatably connected to the center of the cushion block through a bearing, and the end of the connecting rod is fixedly connected with the center of the adjacent side plate. The design of the cushion block, bearing and connecting rod ensures the stability of the turnover process, avoiding shaking or displacement of the device caused by turnover.

[0010] Particularly, the bottom of the two support frames is fixed with a bottom frame for providing overall stability. A lengthened adjusting bolt is threaded through and connected to each of the four corners of the top of the bottom frame, and a washer is rotatably connected to the end of the lengthened adjusting bolt. By rotating the lengthened adjusting bolt, the height and levelness of the device can be adjusted to adapt to different working environments. The cooperation of the lengthened adjusting bolt and the washer enables the device to remain stable on uneven ground, while facilitating height adjustment according to actual needs.

[0011] Further, the two conveying assemblies are in the form of drum conveyors, and the surface of the drum is made of rubber material, which has anti-skid function. The design of the drum conveyor effectively prevents the pulp bag from slipping during conveying, thereby improving the reliability of conveying. In addition, the surface material of the drum conveyor is specially treated, which can ensure the anti-skid performance while reducing damage to the surface of the pulp bag.

DETAILED DESCRIPTION

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] The utility model provides a kind of turnover mechanism for pulp bag, by combining the drawings Figure 1 -attached Figure 5 Detailed description is carried out. The core components of the turnover mechanism include side plate 1, conveying assembly 2, auxiliary U-shaped shell 3, driving mechanism, U-shaped connecting piece 5, support frame 6 and chassis 7 etc. The specific structure of these components, their operating principles in practical application and operation steps will be described in detail as follows.

[0024] As Figure 1 Shown, the overall three-dimensional structure of the whole turnover mechanism clearly shows the layout and mutual relationship of its main components. Two side plates 1 as core support components are respectively located at the left and right sides of the device. Top and bottom two groups of conveying assemblies 2 are provided between side plates 1, and each conveying assembly 2 adopts the form of roller conveyor, with rubber material covering the surface of the roller to ensure sufficient friction force on the pulp bag during conveying to prevent slipping. This design not only improves the conveying efficiency, but also avoids the problem of unstable turnover caused by pulp bag sliding. The two ends of conveying assembly 2 are fixedly connected with sliding block 32, and sliding block 32 is slidably connected with auxiliary U-shaped shell 3 through slide rod 31. As Figure 4 Can be seen from the drawings, slide rod 31 is fixed between four auxiliary U-shaped shells 3, and each slide rod 31 is provided with sliding block 32 at the top and bottom, and one side of sliding block 32 is slidably connected with auxiliary U-shaped shell 3, and the other side is fixedly connected with conveying assembly 2. This design ensures that conveying assembly 2 can move smoothly in the horizontal direction, so as to adjust the distance between the two conveying assemblies 2.

[0025] In order to realize the clamping and fixing of the pulp bag, driving mechanism is arranged at the middle of the side plate 1 adjacent to the surface of conveying assembly 2. As Figure 5As shown, the driving mechanism includes a U-shaped driving housing 4, a reversible toothed screw 41, a small motor 42, and two driving blocks 43. The U-shaped driving housing 4 is fixed to the inner side of the side plate 1, and the reversible toothed screw 41 penetrates through the U-shaped driving housing 4 and is rotationally connected therewith. The male and female teeth of the reversible toothed screw 41 are respectively threadedly connected with the two driving blocks 43, one side of the driving block 43 is slidingly fitted with the U-shaped driving housing 4, and the other side is fixedly connected with the conveying assembly 2. The small motor 42 is fixed to the bottom of the U-shaped driving housing 4, and its output end penetrates through the U-shaped driving housing 4 and is fixedly connected with the reversible toothed screw 41. When the small motor 42 is started, the reversible toothed screw 41 rotates, driving the two driving blocks 43 to move in opposite directions along the screw, thereby pushing the two conveying assemblies 2 to move closer or farther away from each other. In this way, the distance between the two conveying assemblies 2 can be accurately controlled to adapt to pulp bags of different sizes and apply appropriate clamping force. This clamping and fixing design avoids displacement of the pulp bag during the overturning process, thereby ensuring the stability of the overturning.

[0026] Further referring to Figure 3 , the rear side of each of the two side plates 1 is provided with a U-shaped connecting piece 5, one side of each U-shaped connecting piece 5 is fixed with a baffle 51 for enhancing the rigidity of the overall structure. The end of the U-shaped connecting piece 5 is detachably connected with the side plate 1 through an L-shaped mounting piece 52. Four L-shaped mounting pieces 52 are respectively fixed with the two side plates 1 through mounting bolts 53. This design enables the U-shaped connecting piece 5 to be easily assembled and disassembled, while improving the overall stability and maintenance convenience of the device. In addition, the design of the U-shaped connecting piece 5 also provides additional support for the device, especially effectively reducing the shaking of the device during the overturning process.

[0027] As shown in Figure 1 and Figure 2 , each of the opposite sides of the two side plates 1 is provided with a support frame 6 for supporting the entire overturning mechanism. The top of the left support frame 6 is provided with an overturning motor 61, the output end of which is fixed with a rotating rod 62, and the end of the rotating rod 62 is fixedly connected with the center of the adjacent side plate 1. The top of the right support frame 6 is fixed with a cushion block 63, the center of which is rotationally connected with a connecting rod 65 through a bearing 64, and the end of the connecting rod 65 is also fixedly connected with the center of the adjacent side plate 1. When the overturning motor 61 is started, the rotating rod 62 drives the side plate 1 and the conveying assembly 2 thereon to overturn by 180 degrees, turning the bottom surface of the pulp bag to the top surface, facilitating manual removal of the packaging outer skin. The design of the cushion block 63 and the bearing 64 on the right support frame 6 ensures the stability of the overturning process, avoiding shaking or displacement of the device caused by overturning.

[0028] The bottom of the support frame 6 is fixed with a base frame 7 for providing overall stability. As shown in Figure 1As shown, at the top of each corner of the chassis 7, a lengthened adjusting bolt 8 is threaded through and connected, and the end of the lengthened adjusting bolt 8 is in contact with the ground through a washer 81. By rotating the lengthened adjusting bolt 8, the height of the chassis 7 can be independently adjusted to adapt to different working environments. This design enables the device to remain stable on uneven ground while facilitating height adjustment according to actual needs. The design of the washer 81 further enhances the stability of the device, preventing tilting due to uneven ground.

[0029] In actual application scenarios, the operation process of the present turnover mechanism is as follows: S1, place the pail to be turned over on the bottom conveying assembly 2, drive the forward and reverse toothed rod 41 to rotate through the small motor 42, and make the two conveying assemblies 2 move relative to each other and exert appropriate clamping force on the pail. S2, start the turnover motor 61, and the rotating rod 62 drives the side plate 1 and the conveying assembly 2 thereon to turn over by 180 degrees, turning the bottom surface of the pail to the top surface. S3, after the turnover is completed, release the clamping force and take the pail off the conveying assembly 2, completing a turnover operation. Through the above steps, the present turnover mechanism realizes efficient and stable turnover of the pail, meeting the actual needs of the pail processing production line.

[0030] In summary, the present utility model provides an efficient and stable pail turnover mechanism through reasonable structural design and detailed implementation. The device adjusts the spacing of the conveying assembly 2 through the driving mechanism to achieve clamping and fixing, completes 180-degree turnover through the turnover motor 61 driving the side plate 1, and ensures overall stability through the design of the chassis 7 and the lengthened adjusting bolt 8. In addition, the detachable design of the U-shaped connecting piece 5 and the L-shaped mounting piece 52 improves the maintenance convenience of the device. The present turnover mechanism is suitable for various scenarios in the pail processing production line and has wide application prospects.
