Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for woven bag processing, and in particular to a simple support frame device for stacking and bagging woven bags. Background Technology

[0002] Woven bags, as a common packaging material, are widely used in the packaging and transportation of materials in many industries such as chemicals, building materials, and grain. During the production and processing of woven bags, especially when stacking, bagging, or filling, it is usually necessary to use a support frame to open the bag opening and keep it vertical to facilitate subsequent operations.

[0003] However, existing woven bag support devices generally suffer from a lack of flexibility in their structural design. This is mainly manifested in the fixed diameter of the support frame or the cumbersome adjustment method. For example, it is necessary to loosen the bolts one by one, manually adjust the position of each support leg, and then re-tighten them. This step-by-step operation is not only time-consuming and labor-intensive, but also makes it difficult to ensure the consistency of the movement distance of each support leg. This results in irregular bag opening shapes or uneven stress after the bag is opened, which seriously affects the bagging efficiency and quality. In addition, existing support devices often lack convenient and stable self-locking mechanisms in terms of height adjustment. The adjustment process is laborious and prone to height slippage during use, which cannot meet the needs of rapid production switching of woven bags of different specifications.

[0004] Therefore, this utility model proposes a simple support frame device for stacking and bagging woven bags to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low adjustment efficiency, inability to quickly and synchronously adapt to different diameters and lack of convenient and stable self-locking mechanism for adjusting the support height of existing woven bag support devices, this utility model aims to provide a simple support frame device for stacking and bagging woven bags with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a simple support frame device for stacking and bagging woven bags, including: a base plate, and a base frame fixedly connected to the top of the base plate. The top of the base frame is provided with a sliding groove, and a sliding block is slidably connected inside the sliding groove. A support cylinder is fixedly connected to the top of the sliding block, and an extension bracket is slidably connected inside the support cylinder. There is also an adjustment mechanism for driving the sliding block to move synchronously, and a positioning mechanism for locking the height of the extension bracket.

[0007] The adjustment mechanism includes a worm gear, a worm, and an adjustment rod. The worm gear and the worm meshing with it are rotatably connected inside the base plate. An adjustment rod is fixedly connected to the top of the worm gear and rotatably connected inside the base frame. A connecting rod rotatably connects the outer wall of the adjustment rod to the sliding block. The core components of the positioning mechanism include an adjustment groove, a positioning hole, a push frame, a positioning plate, and a positioning insert. The outer wall of the support cylinder has an adjustment groove extending vertically and multiple positioning holes. A push frame is slidably connected inside the adjustment groove. One side of the push frame passes through the adjustment groove and is fixedly connected to the outer wall of the extension bracket. A positioning plate is fixedly connected to the push frame. A positioning insert is slidably connected inside the positioning plate, and one end of the positioning insert can be inserted into the positioning hole.

[0008] Furthermore, the sliding block is connected to the adjusting rod at the center position through the connecting rod to form a radial linkage structure. The extension bracket is nested inside the support cylinder and its vertical position is locked through the cooperation of the positioning rod with the positioning plate and the positioning hole.

[0009] Preferably, in order to facilitate the operator to input power from the outside to drive the adjustment mechanism, a drive rod is rotatably connected inside the base plate. One end of the drive rod is fixedly connected to one end of the worm gear, and the other end of the drive rod extends to the outside of the base plate. This design allows the operator to easily complete the adjustment without directly contacting the internal transmission components.

[0010] Preferably, in order to achieve multi-point uniform support and ensure structural stability, four sliding grooves are provided, and the four sliding grooves are arranged in a circular array on the base frame with the axis of the adjusting rod as the center. The number of sliding blocks, supporting cylinders, extension brackets and connecting rods corresponds one-to-one with the number of sliding grooves, thereby forming a four-bar synchronous drive system.

[0011] Preferably, in order to enhance the guiding stability and structural strength of the positioning rod, two positioning plates are provided, and the two positioning plates are respectively fixedly connected to both sides of the push frame. The positioning rod slides through both positioning plates at the same time. This dual-point support structure effectively prevents the rod from tilting when under force.

[0012] Preferably, in order to achieve rigid interlocking of internal and external components to ensure stability after height adjustment, the extension bracket is provided with a through hole, which corresponds to the positioning hole. One end of the positioning rod can pass through one of the positioning plates and the positioning hole in sequence and be inserted into the inside of the through hole, thereby locking the relative position of the extension bracket and the support cylinder in the vertical direction.

[0013] Preferably, in order to achieve the automatic reset and locking function of the positioning rod, a spring is sleeved on the outer wall of the positioning rod. One end of the spring is fixedly connected to one side of one of the positioning plates, and the other end of the spring is fixedly connected to the outer wall of the positioning rod. The restoring force of the spring ensures that the rod always tends to insert into the positioning hole.

[0014] Preferably, in order to smoothly and safely open the woven bag opening, a semi-circular support rod is fixedly connected to the top of the extension bracket, and the openings of the support rods at the top of the two oppositely arranged extension brackets are opposite to each other. This rounded support end avoids sharp edges from scratching the bag body.

[0015] Preferably, in order to improve the mobility and transmission efficiency of the device, the bottom of the base plate is equipped with casters, and the worm gear is rotatably connected inside the base plate through a bearing. This not only facilitates the relocation of the device in the workshop, but also reduces the frictional resistance when the adjustment mechanism is in operation.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the woven bag support device cannot quickly and synchronously adapt to woven bags of different diameters by setting up a worm gear transmission mechanism in conjunction with a connecting rod assembly. The drive rod drives the worm and worm wheel to rotate, and then the adjusting rod and connecting rod synchronously drive the sliding blocks in four directions to move radially. It achieves the technical effect that only one drive rod needs to be rotated to realize the synchronous opening and closing adjustment of four support arms. Moreover, the self-locking characteristics of the worm gear ensure the stability of the support after adjustment and improve the adaptation efficiency to woven bags of multiple specifications.

[0018] 2. This utility model solves the problems of cumbersome operation and lack of stable self-locking mechanism in the prior art by setting a spring-loaded pin positioning mechanism between the support cylinder and the extension bracket, using the push frame as an external operating handle, and cooperating with the spring-driven positioning rod to penetrate the positioning plate, the support cylinder wall and the internal extension bracket. It achieves the technical effect of being able to unlock and quickly adjust the support height with one hand, and automatically reset and lock when the hand is released, ensuring that the height will not accidentally slip when supporting heavy woven bags, and enhancing the safety and reliability of the device.

[0019] 3. This utility model solves the problems of uneven force distribution at the support points, easy tipping, and sharp edges that easily scratch woven bags in the prior art by adopting a sliding groove layout with a four-point ring array and a semi-circular ring-shaped top support rod design. It achieves the technical effect of evenly distributing the support stress, making the shape of the bag opening more regular after being opened, which is conducive to filling materials, and at the same time effectively protecting the woven bag from mechanical damage.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please refer to Figures 1 to 5 This utility model provides a simple support frame device for stacking and bagging woven bags, which aims to solve the problems of cumbersome adjustment of woven bag support devices in the prior art, inability to quickly and synchronously adapt to different diameters, and lack of a stable self-locking mechanism for adjusting the support height.

[0029] like Figure 1 , Figure 2 as well as Figure 3As shown, the simple support frame device for stacking woven bags mainly consists of a support and adjustment base assembly and a vertical extension support assembly, including a base plate 1 and a base frame 2 fixedly connected to the top of the base plate 1 by bolts or welding. The base plate 1 serves as the foundation for the movement and load-bearing of the entire device. Universal wheels with brake devices are installed at the four corners of its bottom to facilitate workers to easily push the device to the work area and lock it in position during work. The top of the base frame 2 has a sliding groove 3 that extends radially. To ensure the stability and uniform force distribution of the support structure, the number of sliding grooves 3 is set to four, and the four sliding grooves 3 are distributed in a circular array with the center of the base frame 2 as the center. This four-point symmetrical support structure can more evenly distribute the tension applied by the woven bags and avoid tipping or deformation caused by uneven force distribution.

[0030] A sliding block 301 is slidably connected inside the sliding groove 3. The width of the sliding block 301 is adapted to the width of the sliding groove 3 to limit its derailment. A support cylinder 307 is fixedly connected to the top of the sliding block 301. The support cylinder 307 serves as the main structure for vertical support. Its interior is a hollow tubular structure. An extension bracket 308 is slidably connected inside the support cylinder 307. The extension bracket 308 can move up and down along the axial direction of the support cylinder 307 to change the overall support height. In order to adapt to woven bags with different opening shapes and protect the bag opening from being scratched, a semi-circular smooth cylindrical support rod is fixedly connected to the top of the extension bracket 308. The opening directions of the support rods at the top of the two opposite extension brackets 308 are opposite, so that when the four extension brackets 308 are closed, an approximately circular support opening is formed, which can effectively open the bag opening and avoid sharp edges from damaging the woven bag.

[0031] To achieve adaptive adjustment of the woven bag opening diameter, the device integrates a precision transmission adjustment mechanism, such as... Figure 3 As shown, a worm gear 304 and a worm 305 meshing with the outer wall of the worm gear 304 are rotatably connected inside the base plate 1. The worm gear 304 is rotatably mounted at the center of the base plate 1 via a bearing, which greatly reduces the frictional resistance when the worm gear 304 rotates. A vertically upward adjusting rod 302 is fixedly connected to the center of the top of the worm gear 304. The adjusting rod 302 passes through the base plate 1 and extends into the interior of the base frame 2. The adjusting rod 302 and the base frame 2 are rotatably connected, which allows the adjusting rod 302 to serve as the central axis for torque output. A connecting rod 303 is rotatably connected between the outer wall of the adjusting rod 302 and the sliding block 301. The two ends of the connecting rod 303 are respectively hinged to the outer wall of the adjusting rod 302 and the side wall of the sliding block 301 via pins. The number of connecting rods 303, sliding blocks 301, support cylinders 307 and extension brackets 308 all correspond one-to-one with the number of sliding grooves 3, which are four in total, thus forming a synchronous drive mechanism.

[0032] A drive rod 306 is rotatably connected inside the base plate 1. One end of the drive rod 306 is coaxially fixedly connected to one end of the worm gear 305. In order to facilitate the operator to adjust the diameter of the support device, the drive rod 306 adopts an extended rod design, with its other end extending vertically upward and passing through the base plate 1. Finally, its top end extends to the outside or above the base frame 2 for easier access. This design allows the operator to easily rotate the drive rod 306 without bending over and reaching under the base plate 1, thereby driving the internal worm gear 304 and worm gear 305 mechanism to operate. Through the connecting rod 303, the sliding blocks 301 in four directions are pushed and pulled simultaneously to realize the radial opening and closing adjustment of the support structure.

[0033] The outer wall of the support cylinder 307 is provided with an adjustment groove 4 extending vertically and a plurality of positioning holes 401 arranged at equal intervals. The adjustment groove 4 is a long strip-shaped through-slot structure that runs through the side wall of the support cylinder 307. Its length range limits the maximum adjustable stroke of the extension bracket 308. The positioning holes 401 are located on the side of the adjustment groove 4 or at specific geometric positions to provide discrete height positioning points. A push frame 402 is slidably connected inside the adjustment groove 4. The main body of the push frame 402 is located outside the support cylinder 307, but one end of its inner side passes through the adjustment groove 4 and is fixedly connected to the outer wall of the extension bracket 308 located inside the support cylinder 307 by welding or bolts. This connection method makes the push frame 402 the external operating handle of the extension bracket 308. When the operator holds the push frame 402 and slides it up and down along the adjustment groove 4, the internal extension bracket 308 can be directly driven to rise and fall synchronously.

[0034] Meanwhile, in order to lock the height position, a positioning plate 403 is fixedly connected to the push frame 402. To enhance the structural strength and guiding performance of the height adjustment mechanism, two positioning plates 403 are provided, and the two positioning plates 403 are fixedly connected to the opposite side walls of the push frame 402 to form a U-shaped or frame-type mounting seat. Holes are opened in the interior of the positioning plates 403 and positioning rods 405 are slidably connected thereto. The positioning rods 405 pass through the two positioning plates 403 laterally. This double-point support structure effectively restricts the degree of freedom of the positioning rods 405 in the non-axial direction, preventing the rods from tilting or getting stuck when under force. A spring 406 is sleeved on the outer wall of the positioning rods 405. One end of the spring 406 is pressed against or fixedly connected to the inner side wall of one of the positioning plates 403, and the other end of the spring 406 is pressed against or fixedly connected to the boss or retaining ring on the outer wall of the positioning rods 405, so as to always apply a spring force to the positioning rods 405 to return to the direction of the support cylinder 307.

[0035] In conjunction with the aforementioned external structure, the internal extension bracket 308 has a through hole 404. The diameter of the through hole 404 is matched with the end diameter of the positioning rod 405, and the vertical position of the through hole 404 corresponds to the positioning hole 401 on the outer wall of the support cylinder 307. When locking is required, under the elastic force of the spring 406, one end of the positioning rod 405 will pass through the outer positioning plate 403 and the positioning hole 401 on the side wall of the support cylinder 307 in sequence, and finally be inserted into the through hole 404 on the extension bracket 308. Through this multi-layer interlocking, the extension bracket 308 and the support cylinder 307 are rigidly interlocked in the vertical direction, ensuring that the support height will not change unexpectedly when bearing the weight of the woven bag or the operating force, thus having high stability.

[0036] The working principle of this utility model's simple support frame device for stacking and bagging woven bags is as follows:

[0037] When using this device to support woven bags, the radial diameter is first adjusted. The operator holds the handle of the drive rod 306 and rotates it. The drive rod 306 drives the worm 305 at the bottom to rotate synchronously. Since the worm 305 meshes with the worm wheel 304, the rotational motion of the worm 305 is converted into the rotation of the worm wheel 304, which in turn drives the adjusting rod 302, which is coaxially connected to the worm wheel 304, to rotate. The adjusting rod 302 acts as a central drive shaft, and through four connecting rods 303 hinged to its outer wall, it simultaneously applies pushing or pulling forces to the sliding blocks 301 in four directions.

[0038] Driven by the connecting rod 303, the sliding block 301 moves radially back and forth along the sliding groove 3 on the base frame 2. When it is necessary to open a woven bag with a larger diameter, the rotating drive rod 306 causes the sliding block 301 to spread outward, driving the top support cylinder 307 and the extension bracket 308 to move away from each other, thereby expanding the support range. Conversely, it contracts inward, so that even if the external force is removed after the adjustment is in place, the support frame will not automatically retract due to the reaction force of the woven bag, thus ensuring the stability of the support diameter.

[0039] Next, the vertical height is adjusted. The worker holds the pusher 402 with one hand and pulls the positioning rod 405 outwards with the other, overcoming the spring force of the spring 406. This causes the end of the positioning rod 405 to disengage from the positioning hole 401 on the side wall of the support cylinder 307 and the through hole 404 on the extension bracket 308, releasing the vertical locking state. At this point, by moving the pusher 402 up and down, the internal extension bracket 308 slides within the support cylinder 307 until the desired height is reached. Then, the positioning rod 405 is released. Under the restoring force of the spring 406, the positioning rod 405 automatically springs back and passes through the positioning plate 403 and the positioning hole 401 in sequence. If the through hole 404 is aligned at this point, the rod is directly inserted and locked. If not fully aligned, the extension bracket 308 is fine-tuned until the rod falls into the through hole 404, completing the rigid self-locking of the height. Finally, the woven bag is placed on the semi-circular support rods at the top of the four extension brackets 308, completing the bag-supporting operation.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
