Description

Technical Field

[0001] This utility model relates to the field of bag pushing devices, and in particular to a walking wheel assembly mechanism on a bag pushing device. Background Technology

[0002] Currently, in industries such as chemicals and fertilizers, packaging machines are mostly used for packaging powders and granules. The bag pushing device and bag holding mechanism are important components of the packaging machine. During the movement of the bag pushing device, it mainly relies on the driving action of servo motors and linkage mechanisms to push the bag forward. The bag holding structure is realized by a cylinder linkage mechanism.

[0003] Most bag-pushing devices require a guide rail with a certain stroke. Previously, most of them used slide rails or linear bearings for guidance. However, due to the influence of many environmental factors in the chemical and fertilizer industries, the on-site environment is mostly dusty and particulate. Therefore, when slide rails or linear bearings are in such an environment for a long time, the accumulation of surface dust will make it difficult for the bag-pushing device to move, resulting in incomplete bag pushing, delayed work cycle, and high maintenance difficulty. To solve the above problems, a walking wheel group mechanism on the bag-pushing device is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a walking wheel assembly mechanism for a bag-pushing device, which aims to improve the problem in the prior art that "dust will adhere to the surface of the guide rail after a period of use, which will make it difficult for the bag-pushing device to move".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a walking wheel mechanism on a bag-pushing device, comprising a sliding frame and a carrying frame, wherein a clamping assembly is provided on the inner wall of the carrying frame, and a support assembly is provided at the bottom end of the carrying frame, the support assembly comprising a pulley frame, the top end of the pulley frame being fixedly connected to the bottom end of the carrying frame, multiple sets of walking wheels being rotatably connected to the inner wall of the pulley frame, a tensioning wheel being installed near the bottom end of the inner wall of the pulley frame, the walking wheels being in close contact with the outer wall of the sliding frame, a baffle being fixedly connected to the rear end of the pulley frame, and a scraper being rotatably connected to the outer wall of the pulley frame.

[0006] As a further description of the above technical solution:

[0007] The pulley frame is configured in a cross shape, and multiple sets of the traveling wheels are arranged in a rotating array with the center line of the pulley frame as the axis of rotation.

[0008] As a further description of the above technical solution:

[0009] The support components are provided in multiple sets, and the multiple sets of support components are symmetrically arranged with the center line of the baffle as the axis of symmetry.

[0010] As a further description of the above technical solution:

[0011] The clamping assembly includes a right clamping arm, which is rotatably connected to the inner wall of the shelf, and a left clamping arm is rotatably connected to the inner wall of the shelf near its left end.

[0012] As a further description of the above technical solution:

[0013] A cylinder is hinged to the bottom end of the right clamping arm, and the left end of the cylinder output shaft is hinged to the bottom end of the left clamping arm.

[0014] As a further description of the above technical solution:

[0015] A hinge rod is hinged to the rear end of the right clamping arm near the bottom, and the left end of the hinge rod is hinged to the rear end of the left clamping arm near the center.

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

[0017] 1. In this utility model, by setting a baffle, the scattered dust will be blocked by the baffle during the pushing process and will not fall directly onto the surface of the sliding frame. At the same time, a scraper is set so that when the support component moves back and forth, the dust on the surface of the sliding frame will be removed by the scraper, thus keeping the sliding frame clean.

[0024] 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.

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a walking wheel assembly mechanism for a bag-pushing device, including a sliding frame 4 for supporting the movement of the entire device and a carrying frame 1 for carrying goods. The inner wall of the carrying frame 1 is provided with a clamping assembly for fixing the goods. The bottom end of the carrying frame 1 is provided with a support assembly for supporting the movement of the carrying frame 1. The support assembly includes a pulley frame 8 for fixing the walking wheels 9. The top end of the pulley frame 8 is fixedly connected to the bottom end of the carrying frame 1, and the inner wall of the pulley frame 8 is rotatably connected to a mechanism for directly contacting the sliding frame 4. The pulley frame 8 has multiple sets of traveling wheels 9. A tensioning wheel 11 is installed on the inner wall of the pulley frame 8 near the bottom to drive the traveling wheels 9 to fit against the outer wall of the sliding frame 4. The traveling wheels 9 are in close contact with the outer wall of the sliding frame 4. When there is a gap between the traveling wheels 9 and the sliding frame 4, the position of the tensioning wheel 11 can be adjusted to drive the traveling wheels 9 to press the sliding frame 4 tightly. A baffle 5 for blocking dust is fixedly connected to the rear end of the pulley frame 8. A scraper 10 for cleaning the outer wall of the sliding frame 4 is rotatably connected to the outer wall of the pulley frame 8.

[0026] Reference Figure 1 - Figure 3 The pulley frame 8 is cross-shaped, and multiple sets of traveling wheels 9 are arranged in a rotating array around the center line of the pulley frame 8. The multiple sets of traveling wheels 9 can respectively make close contact with the upper surface, left surface and right surface of the pulley frame 8. Multiple sets of support components are provided, and the multiple sets of support components are symmetrically arranged around the center line of the baffle 5. The multiple sets of support components can respectively support both sides of the baffle 5. The clamping component includes a right clamping arm 2 for fixing the goods. The right clamping arm 2 is rotatably connected to the inner wall of the rack 1. A left clamping arm 3 for clamping the goods is rotatably connected to the inner wall of the rack 1 near the left end.

[0027] Reference Figure 1 - Figure 3The bottom end of the right clamping arm 2 is hinged to a cylinder 6 for driving the left clamping arm 3 and the right clamping arm 2 to rotate. The left end of the output shaft of the cylinder 6 is hinged to the bottom end of the left clamping arm 3. The rear end of the right clamping arm 2 is hinged to a hinge rod 7 for driving the left clamping arm 3 and the right clamping arm 2 to rotate simultaneously. The left end of the hinge rod 7 is hinged to the rear end of the left clamping arm 3 near the center. The left clamping arm 3 and the right clamping arm 2 are connected by the hinge rod 7. When the left clamping arm 3 rotates, it will drive the right clamping arm 2 to rotate in the opposite direction by pushing the hinge rod 7.

[0028] Working principle: When goods need to be transferred, the goods to be transported can be placed on the top of the rack 1. Then, the cylinder 6 can be activated to extend it. The extension of the cylinder 6 will push the left clamping arm 3 to rotate. The left clamping arm 3 will push the hinge rod 7 to drive the right clamping arm 2 to rotate. By rotating the left clamping arm 3 and the right clamping arm 2, the items can be clamped and fixed on the top of the rack 1. Then, the rack 1 can be moved to move the items. When the rack 1 moves back and forth, the baffle 5 will block the falling dust to prevent the dust from falling on the outer wall of the sliding rack 4. At the same time, when the rack 1 moves, it will drive the pulley frame 8 to move. The movement of the pulley frame 8 will remove the dust on the surface of the sliding rack 4, thus keeping the outer wall of the sliding rack 4 clean.
