Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to an automatic positioning and opening device for filter bags. Background Technology

[0002] Bag filters are used in fresh air filtration systems or equipment. A bag filter consists of multiple (e.g., six) filter bags assembled side-by-side. The process is roughly as follows: one end of the filter bag is open. First, adhesive is sprayed onto the outer surface of the inner frame. Then, the adhesive-coated inner frame is placed inside the opening of the filter bag (the filter bag needs to have its opening pre-opened) and the two are pressed and clamped together (this can be called a composite clamping of the filter bag and the inner frame). Next, two adjacent filter bags (mainly the inner frames) are riveted together. Finally, a large outer frame assembles the inner frames of the multiple filter bags together. To automate this process, each step must be automated. In current technology, the filter bag feeding and opening processes are generally performed manually, resulting in low efficiency, low automation, and high labor costs. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide an automatic positioning and opening device for filter bags. The device has an ingenious structural design and can automatically grasp, position, and open the filter bags. It has a high degree of automation and high efficiency, and can ensure the consistency of the opening degree of the filter bag, which facilitates the smooth assembly process with the inner frame.

[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: an automatic positioning and opening device for filter bags is provided. The positioning and opening device includes a positioning frame, a positioning platform, an upper opening mechanism, and a bag-grabbing mechanism for gripping filter bags and capable of translating along the X-axis and Z-axis. The front end of the positioning platform is provided with several positioning base plates, a lower opening mechanism, and a bag-pushing mechanism.

[0005] The positioning platform has several strip-shaped grooves extending along the X direction. The bag pushing mechanism includes a bag pushing plate and a bag pushing translation driving unit that can drive the bag pushing plate to translate. The bag pushing plate is driven to translate along the X direction by the bag pushing translation driving unit.

[0006] The filter bag is picked up by the bag-grabbing mechanism and placed on the positioning platform. The bag-pushing translation drive unit pushes the bag-pushing plate to translate and cooperate with the positioning base plate to accurately position the filter bag. The upper bag-opening mechanism inserts the upper layer of the filter bag and moves it upward, and the lower bag-opening mechanism inserts the lower layer of the filter bag and moves it downward, thereby opening the mouth of the filter bag.

[0007] Furthermore, the bag-pushing translation drive unit includes a bag-pushing translation drive motor, two synchronous pulleys, a synchronous belt, and a bag-pushing seat. The synchronous pulleys are located at both ends of the bottom of the positioning platform. One of the synchronous pulleys is installed at the power output end of the bag-pushing translation drive motor. The synchronous belt is fitted onto the synchronous pulley. The bag-pushing seat is fixed on the synchronous belt. The upper end of the bag-pushing seat extends out from the strip groove and is fixedly installed with the bag-pushing plate.

[0008] Furthermore, the upper bag opening mechanism includes an upper needle suction cup and an upper bag opening drive linear module. The upper needle suction cup is installed at the power output end of the upper bag opening drive linear module, and the upper needle suction cup is driven to rise and fall by the upper bag opening drive linear module.

[0009] Furthermore, the lower opening bag mechanism includes a lower needle suction cup and a lower opening bag driving cylinder. The lower needle suction cup is installed at the power output end of the lower opening bag driving cylinder, and the lower needle suction cup is driven to rise and fall by the lower opening bag driving cylinder.

[0010] Furthermore, the bag-retrieving mechanism includes a connecting arm and a suction cup assembly consisting of multiple needle-type suction cups, the suction cup assembly being mounted on the lower end of the connecting arm.

[0011] To elaborate further, the X-axis bag-taking translation drive mechanism that can drive the bag-taking mechanism to translate along the X-axis is a linear module.

[0012] Furthermore, the Z-axis bag-taking translation drive mechanism capable of driving the bag-taking mechanism to translate along the Z-axis includes a Z-axis translation drive motor, a drive wheel, an upper idler wheel, a lower idler wheel, and a belt. The drive wheel is located above the upper idler wheel, and the upper idler wheel is located above the lower idler wheel. The upper end of the belt is fixed to the upper end of the connecting arm. At the same time, the belt wraps around from below the upper idler wheel to the outer periphery of the drive wheel, then wraps around from above the lower idler wheel, and finally the lower end of the belt is fixed to the lower end of the connecting arm.

[0013] The beneficial effects of this utility model are:

[0014] This utility model includes a positioning frame, on which are provided a positioning platform, an upper bag opening mechanism, and a bag-grabbing mechanism for gripping filter bags and capable of translating along the X and Z axes.

The bag pushing mechanism includes a bag pushing plate and a drive mechanism for pushing the bag. The bag grabbing mechanism grips the filter bag onto the positioning platform, and the bag pushing translation drive unit drives the bag pushing plate to translate and cooperate with the positioning base plates to accurately position the filter bag.

Therefore, this utility model has an ingenious structural design, enabling automatic gripping, automatic positioning, and automatic opening of the filter bag. It has a high degree of automation and high efficiency, and can ensure the consistency of the opening degree of the filter bag, facilitating the smooth subsequent assembly process with the inner frame.

[0025] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0026] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0027] Example: An automatic positioning and opening device for filter bags, such as... Figures 1 to 5 As shown, the positioning and bag opening device 3 includes a positioning frame 31, on which a positioning platform 32, an upper bag opening mechanism 33 and a bag picking mechanism 34 for gripping the filter bag 1001 and being able to translate along the X-axis and Z-axis are provided. The front end of the positioning platform is provided with several positioning base plates 321, a lower bag opening mechanism 35 and a bag pushing mechanism 36.

[0028] The positioning platform 32 has several strip grooves 322 extending along the X direction. The bag pushing mechanism 36 includes a bag pushing plate 361 and a bag pushing translation driving unit 362 that can drive the bag pushing plate 361 to translate. The bag pushing plate is driven to translate along the X direction by the bag pushing translation driving unit 362.

[0029] The filter bag is picked up by the bag-grabbing mechanism 34 and placed on the positioning platform 32. The bag-pushing translation drive unit 362 pushes the bag-pushing plate 361 to translate and cooperate with the positioning base plate 321 to accurately position the filter bag. The upper bag-opening mechanism 33 inserts the upper layer of the filter bag 1001 and moves it upward, and the lower bag-opening mechanism 35 inserts the lower layer of the filter bag and moves it downward, thereby opening the mouth of the filter bag.

[0030] In this embodiment, as Figures 1 to 5As shown, the bag-pushing translation drive unit 362 includes a bag-pushing translation drive motor 3621, two synchronous pulleys 3622, a synchronous belt 3623, and a bag-pushing seat 3624. The synchronous pulleys are located at both ends of the bottom of the positioning platform. One of the synchronous pulleys is installed at the power output end of the bag-pushing translation drive motor. The synchronous belt is fitted onto the synchronous pulley. The bag-pushing seat is fixed on the synchronous belt. The upper end of the bag-pushing seat extends out from the strip groove and is fixedly installed with the bag-pushing plate.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the upper bag opening mechanism 33 includes an upper needle-type suction cup 331 and an upper bag opening drive linear module 332. The upper needle-type suction cup is installed at the power output end of the upper bag opening drive linear module, and the upper needle-type suction cup is driven to rise and fall by the upper bag opening drive linear module. The needle-type suction cup is a type of modern suction cup technology, mainly using a thin needle-shaped rigid rod as the suction cup adsorption area. It features strong adsorption force, firm adsorption, and simple structure. The working principle of the needle-type suction cup is mainly achieved by creating negative pressure inside the suction cup, which is existing technology and will not be elaborated further.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the lower opening bag mechanism 35 includes a lower needle suction cup 351 and a lower opening bag driving cylinder 352. The lower needle suction cup is installed at the power output end of the lower opening bag driving cylinder, and the lower needle suction cup is driven to rise and fall by the lower opening bag driving cylinder.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the bag-retrieving mechanism 34 includes a connecting arm 341 and a suction cup group 342 composed of multiple needle-type suction cups, the suction cup group being installed at the lower end of the connecting arm.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the X-axis bag-taking translation drive mechanism 37, which drives the bag-taking mechanism 34 to translate along the X-axis, is a linear module. It only needs to be able to drive the bag-taking mechanism to move stably up and down.

[0035] In this embodiment, as Figure 6 and Figure 7As shown, the Z-axis bag-taking translation drive mechanism 38, which drives the bag-taking mechanism 34 to translate along the Z-axis, includes a Z-axis translation drive motor 381, a drive wheel 382, ​​an upper idler wheel 383, a lower idler wheel 384, and a belt 385. The drive wheel is located above the upper idler wheel, and the upper idler wheel is located above the lower idler wheel. The upper end of the belt is fixed to the upper end of the connecting arm. Simultaneously, the belt wraps around from below the upper idler wheel to the outer circumference of the drive wheel, then wraps around from above the lower idler wheel, and finally the lower end of the belt is fixed to the lower end of the connecting arm. The connecting arm 341 and the mounting base 386 where the Z-axis translation drive motor is located are slidably connected via a slider-rail structure. In this embodiment, the rail extends along the Z-axis and is disposed on the surface of the connecting arm, and the slider is fixed to the surface of the mounting base. Figure 6 As shown, when the Z-axis translation drive motor drives the drive wheel to rotate counterclockwise, it will cause the connecting arm to rise; conversely, when the Z-axis translation drive motor drives the drive wheel to rotate clockwise, it will cause the connecting arm to fall. Of course, other Z-axis bag-retrieving translation drive mechanisms can also be used, as long as they can achieve the function of driving the connecting arm to rise and fall. However, compared to the motor-driven screw and nut structure, the Z-axis bag-retrieving translation drive mechanism in this embodiment has a longer drive stroke and runs more smoothly, thus meeting the requirements.

[0036] The working principle and process of this utility model:

[0037] The filter bags are stacked in the feeding area. The bag picking mechanism moves along the X-axis to the feeding area of ​​the filter bags, and then descends along the Z-axis to the position where the suction cup group picks up the top filter bag and places it on the positioning platform. Then, the bag pushing translation drive unit 362 drives the bag pushing plate to translate along the X-direction to push the filter bag and accurately position it with the positioning base plate as the base plate as the reference. Then, the upper bag opening drive linear module drives the upper needle suction cup to descend to the position and pick up the upper layer of the filter bag. At the same time, the lower bag opening drive cylinder drives the lower needle suction cup to rise and pick up the lower layer of the filter bag. Then, the upper bag opening drive linear module drives the upper needle suction cup to move upward and the lower bag opening drive cylinder drives the lower needle suction cup to move downward, which can open the mouth of the filter bag. In order to ensure the opening effect of the filter bag, multiple sets of upper bag opening mechanism 33 and lower bag opening mechanism can be set at intervals.

[0038] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
