Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanisms, and in particular relates to an automatic feeding mechanism for reaction tanks. Background Technology

[0002] The reaction vessel is the core equipment in adhesive production, used for mixing, reacting, and synthesizing raw materials. Its design must comprehensively consider reaction conditions, material compatibility, and ease of operation. Reaction vessels are typically made of corrosion-resistant and high-temperature-resistant stainless steel and are equipped with a stirring system, a heating / cooling system, a feeding and discharging system, and an automated control system. The stirring system uses different types of stirrers depending on the reaction requirements. The heating / cooling system achieves precise temperature control through jackets or coils, while the automated control system uses PLCs and sensors to monitor parameters such as temperature, pressure, and liquid level in real time, ensuring the efficiency and stability of the reaction process.

[0003] When adhesives are mixed in a reaction vessel, various high-viscosity liquid materials, such as liquid resin, liquid curing agent, plasticizer, and additives, need to be added during the mixing process. However, the traditional method of adding them manually is inefficient, cumbersome, and difficult to control the amount added precisely, resulting in differences in the performance of adhesives produced each time. Furthermore, the performance standards for sheet metal adhesives used in vehicle sheet metal are quite high.

[0004] To address the aforementioned problems, this application proposes an automatic feeding mechanism for reaction vessels. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding mechanism for reaction vessels, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic feeding mechanism for a reaction vessel, comprising a diaphragm pump mounted on a mounting frame, the discharge port of the diaphragm pump being connected to the reaction vessel, a material seat being provided on one side of the mounting frame, and further comprising:

[0008] Material box, which is pulled out and works with material holder to hold materials;

[0009] The suction pipe is connected at the lower end to the material seat and material box, and at the upper end to the diaphragm pump through a hose and inlet.

[0010] A positioning sleeve, fixed on the material seat and sleeved on the outside of the suction pipe, is an automatic feeding mechanism for a reaction vessel.

[0011] The locking mechanism is fixed to the upper inner side of the material seat and works in conjunction with the lifting and lowering of the suction pipe inside the material seat to lock or release the material box within the material seat.

[0012] Furthermore, a guide tube is vertically fixed at the upper end of the material seat, the guide tube is interconnected with the interior of the material seat, and the suction tube slides vertically along the guide tube.

[0013] Furthermore, a positioning post and a handle are fixedly provided on the outer side of the suction tube, and a movable groove for the positioning post to move is provided in the positioning sleeve. A positioning groove is provided on the top side of the movable groove to prevent the suction tube from falling and to cooperate with the positioning post.

[0014] Furthermore, the bottom of the suction tube is provided with an anti-clogging groove, the handle is located outside the positioning sleeve, and the length of the movable groove is greater than the depth to which the suction tube is inserted into the material box.

[0015] Furthermore, the locking mechanism includes an active rotating plate hinged to the top of the inner side of the material seat and a passive rotating rod disposed at one end of the active rotating plate and hinged to the top of the inner side of the material seat, wherein the passive rotating rod consists of two symmetrically arranged rods.

[0016] Furthermore, one end of the active rotating plate is provided with a contact that cooperates with the suction pipe, and a return spring that abuts against each other is provided between the upper end of the active rotating plate near the contact and the material seat. The other end of the active rotating plate is provided with a drive sleeve, which is at least partially sleeved on one end of the passive rotating rod.

[0017] Furthermore, a locking block is fixed to the other end of the passive rotating rod, and a stop block that contacts the locking block is fixed to the top inner side of the material seat.

[0018] This utility model has the following beneficial effects:

[0019] This utility model has the advantage of low cost by setting up a lifting suction pipe and a pull-out material box. At the same time, the positioning sleeve is set up to cooperate with the suction pipe, which facilitates the picking and placing of the material box on the material seat. Then, the reaction vessel is fed through a hose and a diaphragm pump. The diaphragm pump can realize the automation of feeding, while ensuring feeding accuracy and ensuring the quality and consistency of the finished adhesive.

[0020] This invention features a locking mechanism between the material seat and the material box, which works in conjunction with the lifting and lowering of the suction pipe. The locking mechanism automatically disengages the material box after the suction pipe rises, facilitating its removal from the material seat. Conversely, it automatically locks the material box in the material seat after the suction pipe descends, preventing the box from detaching during the feeding process and ensuring stability and reliability.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] 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 scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Please see Figure 1 - Figure 6 As shown, this utility model is:

[0034] An automatic feeding mechanism for a reaction vessel includes a diaphragm pump 2 mounted on a mounting frame 1, with a discharge port 22 on the diaphragm pump 2 connected to the reaction vessel. A material seat 3 is provided on one side of the mounting frame 1. The mechanism also includes:

[0035] Material box 4 is pulled out and cooperates with material seat 3 to hold materials. Material seat 3 has an opening on the side for taking out and putting in material box 4. The top of material box 4 has an opening to facilitate the extraction of suction pipe 5. Material box 4 and material seat 3 are combined to form a closed space to prevent dust.

[0036] The lower end of the suction pipe 5 is connected to the material seat 3 and the material box 4, and the upper end is connected to the diaphragm pump 2 through the hose 8 and the feed port 21. The anti-clogging groove 53 at the bottom of the suction pipe 5 prevents the bottom from completely sticking to the material box 4, which would prevent the material from being sucked up.

[0037] Positioning sleeve 6, fixed on material seat 3 and sleeved on the outside of suction pipe 5, is an automatic feeding mechanism for a reaction vessel.

[0038] The locking mechanism 7 is fixed on the upper inner side of the material seat 3 and works in conjunction with the lifting and lowering of the suction pipe 5 inside the material seat 3 to lock or release the material box 4 in the material seat 3.

[0039] The material seat 3 has a guide tube 31 vertically fixed at its upper end. The guide tube 31 is interconnected with the inside of the material seat 3. The suction pipe 5 slides vertically along the guide tube 31. In this embodiment, the guide tube 31 is used to guide and support the suction pipe 5. The guide tube 31 can be fixed to the material seat 3 by welding. The suction pipe 5 slides against the inner wall of the guide tube 31.

[0040] The suction pipe 5 is fixedly provided with a positioning post 51 and a handle 52 on one side of its exterior. The positioning sleeve 6 is provided with a movable groove 61 for the positioning post 51 to move. The top side of the movable groove 61 is provided with a positioning groove 62 to prevent the suction pipe 5 from falling and to cooperate with the positioning post 51. In this embodiment, the cooperation of the positioning post 51, the movable groove 61 and the positioning groove 62 can conveniently and reliably limit the suction pipe 5 after it is lifted, thereby improving the feeding efficiency of the material box 4.

[0041] The suction pipe 5 has an anti-clogging groove 53 at its bottom, and the handle 52 is located outside the positioning sleeve 6. The length of the movable groove 61 is greater than the depth of the suction pipe 5 inserted into the material box 4. In this embodiment, when the positioning post 51 is located at the bottom of the movable groove 61, the bottom of the suction pipe 5 is located at the bottom of the inner side of the material box 4. When the handle 52 is located at the top of the movable groove 61, the bottom of the suction pipe 5 is completely higher than the material box 4 but does not detach from the guide tube 31, so as to facilitate the picking and putting of the material box 4.

[0042] The locking mechanism 7 includes an active rotating plate 71 hinged to the top of the inner side of the material seat 3 and a passive rotating rod 72 disposed at one end of the active rotating plate 71 and hinged to the top of the inner side of the material seat 3. The passive rotating rods 72 are two symmetrically arranged rods. In this embodiment, the active rotating plate 71 and the two passive rotating rods 72 cooperate to form two symmetrical locking points between the material seat 3 and the material box 4, ensuring stability.

[0043] The active rotating plate 71 has a contact 711 at one end that cooperates with the suction pipe 5. The upper end of the active rotating plate 71 near the contact 711 is provided with a return spring 74 that abuts against each other between it and the material seat 3. The other end of the active rotating plate 71 is provided with a drive sleeve 712. The drive sleeve 712 is at least partially sleeved on one end of the passive rotating rod 72. In this embodiment, the drive sleeve 712 has an internal space for the passive rotating rod 72 to move, and can also adapt to the position difference formed when the two move, so as to ensure effective power transmission.

[0044] In this embodiment, a locking block 721 is fixed to the other end of the passive rotating rod 72, and a stop block 73 that contacts the locking block 721 is fixed to the top inner side of the material seat 3. Figure 5 The locking block 721 shown is in contact with both the stop block 73 and the material box 4. The material box 4 is in a locked state. When the passive rotating rod 72 rotates the locking block 721 upward, it will disengage from the material box 4, thus releasing the material box 4 from the lock.

[0045] Understandably, by combining the suction pipe with the pull-out material box, along with the positioning sleeve and diaphragm pump, a low-cost, automated feeding process is achieved, ensuring feeding accuracy and consistent quality of the finished adhesive. At the same time, the locking mechanism automatically locks or disengages from the material box when the suction pipe is raised or lowered, simplifying the picking and placing of the material box and improving the stability and reliability of the feeding process.

[0046] One specific application of this embodiment is: adding adhesive to the inside of the material box 4 to produce the required liquid material, and then inserting the suction pipe 5 into the inside of the material box 4. The upper end of the suction pipe 5 is connected to the inlet 21 through the hose 8, and the outlet 22 is connected to the inside of the reaction vessel through the hose.

[0047] The working time or interval of the diaphragm pump 2 is controlled by the controller. When the diaphragm pump 2 is working, liquid materials are added into the reaction tank through the suction pipe 5 and the hose 8.

[0048] Adding materials to material box 4: Stop the diaphragm pump 2, lift the suction pipe 5 upwards by using handle 52, the suction pipe 5 moves upwards from inside the material box 4, the positioning column 51 moves from the bottom to the top of the movable slot 61, then rotate the suction pipe 5 to lock the positioning column 51 in the positioning slot 62, at this time the bottom of the suction pipe 5 is higher than the bottom of the guide tube 31, the material box 4 can be taken out from the side of the material seat 3, then add materials to the material box 4 and put it back into the material seat 3, rotate the suction pipe 5 in the opposite direction to move the positioning column 51 from the positioning slot 62 to the movable slot 61, move the suction pipe 5 downwards, the bottom of the suction pipe 5 is inserted into the materials in the material box 4, and the material addition work in the material box 4 is completed;

[0049] The principle of locking mechanism 7: as follows Figure 5 The suction pipe 5 shown is inserted into the material box 4. In this state, the outer wall of the suction pipe 5 is partially in contact with the contact 711, and the contact 711 is lower than the hinge axis between the active rotating plate 71 and the material seat 3, while the drive sleeve 712 is higher than the hinge axis. The drive sleeve 712 drives the locking block 721 at the other end of the passive rotating rod 72 to the lowest position. The locking block 721 forms a block between the bottom inner end of the material box 4 and the stop block 73. The return spring 74 is in a stretched state, and the material box 4 is in a locked state. When When the suction pipe 5 moves upward, after it disengages from the contact 711, the active rotating plate 71 and the passive rotating rod 72 reset under the action of the return spring 74. Through the lever principle, the locking block 721 moves upward until it disengages from the material box 4, thus disengaging the material box 4 from the material seat 3. After the suction pipe 5 is inserted downward again, it will push the contact 711 part downward first, and then place it on the side to drive the locking mechanism 7 to lock. The return spring 74 is used to disengage the locking mechanism 7.
