Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for a packaging machine. Background Technology

[0002] A baling machine, also known as a strapping machine, strapping machine, or bundling machine, uses strapping tape to bundle products or packages, then tightens it and joins the ends using a heat-sealing head. The function of a baling machine is to reinforce packaged goods, preventing them from scattering during handling and storage due to loose strapping, while also ensuring neat and aesthetically pleasing bundling.

[0003] Patent CN202321680426.7 discloses a feeding device for a packaging machine. A linear lifting module lowers a clamping module to a clamping position, where it grips the box to be packaged. The linear lifting module then raises the box to a suitable height, and a linear motion module positions the clamped box on the upper part of the packaging machine. Finally, the linear lifting module places the clamped box on the machine's table. When packaging boxes in a grid pattern, the clamping module grips the box, and a rotating module rotates the box. This feeding device can handle heavy boxes, reducing manual handling and increasing production efficiency.

[0004] The above-mentioned device has the following problems: the clamping module clamps the box through the clamping arm, which is very easy to damage the box; when the clamping module clamps the box onto the packing table, it is still necessary to manually push the box to the designated packing position, which cannot achieve fully automatic packing and consumes manpower.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a feeding device for a packaging machine in order to achieve a more practical purpose. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding device for a baling machine to solve the problems mentioned in the background art. In view of the above problems, the technical solution proposed by this utility model is: a feeding device for a baling machine, including a worktable, a moving mechanism, a clamping mechanism, and a load-bearing plate. The worktable has a working cavity, and the bottom of the working cavity is provided with a pair of parallel first-order sliding grooves and a pair of parallel second-order sliding grooves, with the pair of second-order sliding grooves located between the pair of first-order sliding grooves. Matching locking blocks are provided within the pair of second-order sliding grooves. A placement cavity is provided at the bottom of the working cavity, and a second cylinder is provided at the end of the placement cavity. The output end of the second cylinder faces the front end and is fixedly connected to the locking block via a connecting rod. A lifting groove is provided at the end of the working cavity, and a matching vertically movable bracket is provided within the lifting groove. The bracket extends into the working cavity. The moving mechanism includes two support plates located on both sides of the worktable. A pair of parallel support rods are mounted on the top of the two support plates, and a track is provided on the opposite side of the pair of support rods. Two parallel connecting rods are provided between the support rods. Each end of the connecting rod has a pulley that matches the track. A small motor is located directly below each pulley, and the output end of the small motor is fixedly connected to the sliding shaft of the pulley. A clamping mechanism is located directly below the moving mechanism. The clamping mechanism includes a first cylinder, a clamping seat, a clamping cavity, a telescopic rod, a wedge-shaped clamping block, and a spring. The output end of the cylinder faces downwards and is fixed to the clamping seat. A cylindrical clamping cavity is formed inside the clamping seat, extending through the bottom of the clamping seat. Telescopic components are located on both sides of the bottom of the clamping cavity. The spring is sleeved on the outside of the telescopic components. The wedge-shaped clamping block is fixed to one end of the telescopic components near the clamping cavity. When the spring is fully extended, the wedge-shaped clamping block extends into the clamping cavity. The top of the first cylinder is fixedly connected to the connecting rod. A load-bearing plate is located directly below the clamping mechanism, and the top of the load-bearing plate stores the packaged materials.

[0007] Furthermore, each of the four corners of the load-bearing plate is provided with a base, the columnar top of the base is provided with a fixing block, and the middle of the base is provided with a sliding block. The sliding block can slide up and down in the middle of the base. The four bases are located directly below the clamping seat, and the four bases correspond one-to-one with the clamping seat.

[0008] Furthermore, the top diameter of the fixing block is the same as the bottom diameter of the sliding block, the bottom diameter of the fixing block is the same as the top diameter of the sliding block, the bottom diameter of the fixing block is the same as the diameter of the clamping cavity, and the sides of both the fixing block and the sliding block are arc-shaped.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, normally, the sliding block moves away from the fixed block under the action of gravity. When the No. 1 cylinder starts to output, it causes the clamping seat to press down, and the fixed block enters the clamping cavity. Under the action of the spring and the telescopic component, the wedge-shaped clamping block slides past the fixed block. At this time, the No. 1 cylinder stops pressing down and retracts. At this time, the spring rebounds, causing the top of the wedge-shaped clamping block to press against the bottom of the fixed block, thereby achieving the clamping of the base and the load-bearing plate. If the No. 1 cylinder drives the clamping seat to continue pressing down, the wedge-shaped clamping block can slide past the sliding block. At this time, the No. 1 cylinder retracts, and the wedge-shaped clamping block drives the sliding block to move upward, so that the sliding block and the fixed block fit tightly together. The bottom diameter of the fixed block is the same as the top diameter of the sliding block. The sides of both the fixed block and the sliding block are arc-shaped. Therefore, the wedge-shaped clamping block can easily detach from the fixed block and the sliding block, stopping the clamping of the base and the load-bearing plate.

[0010] Furthermore, a matching support groove is provided on the side of the load-bearing plate near the bracket, and when the load-bearing plate is located in the working cavity, the top of the bracket is slightly lower than the top of the load-bearing plate.

[0011] Furthermore, a hydraulic cylinder is provided at the bottom of the bracket, and the bottom of the bracket is fixedly connected to the output end of the hydraulic cylinder. When the hydraulic cylinder is in the initial state, the bottom of the bracket is flush with the bottom surface of the working chamber.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by inserting the bracket into the load-bearing plate and simultaneously activating the hydraulic cylinder, the bracket can move the packaged material on the top of the load-bearing plate to the packaging position on the workbench surface, thereby carrying out subsequent packaging work.

[0013] Furthermore, the bottom of the load-bearing plate is provided with a slot that matches the card block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the load-bearing plate falls into the working chamber, the locking block is locked into the locking slot, and the load-bearing plate can be driven to reciprocate within the working chamber by the No. 2 cylinder.

[0015] Furthermore, the bottom of the load-bearing plate is provided with directional wheels that match the width of the first sliding groove.

[0016] The beneficial effects of adopting the above-mentioned further solution are that when the load-bearing plate is on the ground, it is easy to push the load-bearing plate to move and facilitate the transportation and packaging of materials. When the load-bearing plate is in the working chamber, the directional wheels reduce the friction between the load-bearing plate and the working chamber, making it easier for the load-bearing plate to move in the working chamber while also playing a limiting role.

[0017] Furthermore, the support rod is located above the front end of the worktable and perpendicular to the worktable, and a limiting block is provided on one side of the support rod.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the moving mechanism conveys the packaged materials above the workbench, and the limit block prevents the moving mechanism from losing its position during conveyance.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a clamping mechanism to clamp the load-bearing plate and cooperating with a moving mechanism to move along the support rod, the load-bearing plate and the packaging material can be transported from the ground to the working chamber of the workbench. Then, a second cylinder drives the load-bearing plate to move within the working chamber to below the packaging position. Subsequently, a hydraulic cylinder drives the support to move upward, thereby moving the packaging material upward to the packaging position for packaging. After packaging is completed, the support falls down, and the packaged material falls onto the load-bearing plate and returns to the ground along the same path. It is then transported to the next process via the load-bearing plate. This device requires no manual intervention during use, realizing automated material loading for packaging. There is no need for manual adjustment of the material position, which greatly saves manpower. Using the load-bearing plate as a carrier to transport materials avoids deformation and damage to the materials due to compression during transportation, thus saving costs.

The support rod 2002 is located above the front end of the worktable 100 and is perpendicular to the worktable 100. A limit block 2006 is provided on one side of the support rod 2002 to prevent the moving mechanism 200 from losing its position.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a clamping mechanism 300 is provided directly below the moving mechanism 200. The clamping mechanism 300 includes a first cylinder 3001, a clamping seat 3002, a clamping cavity 3003, a telescopic rod 3004, a wedge-shaped clamping block 3005, and a spring 3006. The output end of the cylinder 3001 faces downward and is fixed to the clamping seat 3002. A columnar clamping cavity 3003 is provided inside the clamping seat 3002. The clamping cavity 3003 penetrates the bottom of the clamping seat 3002. Telescopic components 3004 are provided on both sides of the bottom of the clamping cavity 3003. The spring 3006 is sleeved on the outside of the telescopic components 3004. A wedge-shaped clamping block 3005 is fixed at one end of the telescopic components 3004 near the clamping cavity 3003. When the spring 3006 is fully extended, the wedge-shaped clamping block 3005 extends into the clamping cavity 3003. The top of the first cylinder 3001 is fixedly connected to the connecting rod 2005.

[0033] Please see Figure 1 - Figure 7This utility model provides a technical solution: a load-bearing plate 400 is provided directly below the clamping mechanism 300, and the top of the load-bearing plate 400 stores the packaging material 500. Bases 4002 are provided at each of the four corners of the load-bearing plate 400. A fixing block 4004 is provided at the columnar top of each base 4002, and a sliding block 4003 is provided in the middle of each base 4002. The sliding block 4003 can slide up and down in the middle of the base 4002. The four bases 4002 are located directly below the clamping seat 3002, and the four bases 4002 are connected to the clamping mechanism 3002. The gripper 3002 corresponds one-to-one with the fixed block 4004. The top diameter of the fixed block 4004 matches the bottom diameter of the sliding block 4003, and the bottom diameter of the fixed block 4004 matches the top diameter of the sliding block 4003. The bottom diameter of the fixed block 4004 matches the diameter of the gripping cavity 3003. Both the fixed block 4004 and the sliding block 4003 have arc-shaped sides. Normally, the sliding block 4003 moves away from the fixed block 4004 under gravity. When the first cylinder 3001 starts outputting, it causes the gripper 3002 to press down, and the fixed block... 4004 enters the clamping cavity 3003. Under the action of spring 3006 and telescopic component 3004, wedge-shaped clamping block 3005 slides past fixed block 4004. At this time, cylinder 3001 stops pressing down and retracts. The spring rebounds, causing the top of wedge-shaped clamping block 3005 to press against the bottom of fixed block 4004, thereby clamping the base 4002 and the load-bearing plate. If cylinder 3001 drives clamping seat 3002 to continue pressing down, wedge-shaped clamping block 3005 can slide past the sliding block. When block 4003 is engaged, cylinder 3001 retracts, and wedge-shaped clamping block 3005 moves sliding block 4003 upward, so that sliding block 4003 and fixed block 4004 fit tightly together. The bottom diameter of fixed block 4004 is the same as the top diameter of sliding block 4003. The sides of fixed block 4004 and sliding block 4003 are both arc-shaped, so wedge-shaped clamping block 3005 can easily disengage from fixed block 4004 and sliding block 4003, stopping the clamping of base 4002 and load-bearing plate 400.

[0034] Specifically, the working principle and usage of the feeding device for this type of baling machine are as follows: Before use, check whether all parts of the device are intact. Then, place the baling material 500 on the support plate 400 and push the support plate 400 directly below the clamping mechanism 300. The first cylinder 3001 drives the clamping seat 3002 to press down and complete the clamping of the support plate 400. Then, under the action of the moving mechanism, the clamping mechanism 300 and the support plate 400 below it are moved to the working chamber 1001 of the worktable 100. Then, the first cylinder 3001 drives the clamping seat 3002 to press down and end the clamping. At this time, the slot 400 at the bottom of the support plate 400 engages with the clamping block 1005. Then, the output end of the second cylinder 1006 retracts, thereby moving the support plate 400 to the baling position inside the working chamber 1001. Directly below, the bracket 1007 is inserted into the bracket slot 4005 within the load-bearing plate 400. Simultaneously, the hydraulic cylinder is activated, causing the bracket 1007 to move the packaged material 500 on top of the load-bearing plate 400 to the packaging position on the workbench 100 for subsequent packaging work. After packaging is complete, the bracket 1007 moves down, and the load-bearing plate 400 and the packaged material return to the ground for the next process. This device requires no manual intervention, achieving automated material loading for packaging. It eliminates the need for manual adjustment of material positions, greatly saving manpower. By using the load-bearing plate 400 as a carrier to transport the packaged material 500, it prevents the packaged material 500 from being deformed or damaged due to compression during packaging and transportation, thus saving costs. The device has a simple structure, is easy to operate, and has high practical value.
