Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for production of organic silicon resin, in particular to a feeding device for production of organic silicon resin. Background Art

[0002] Silicone resin (also known as polysiloxane) is a general term for a class of polymers whose skeletons are composed of alternately linked silicon atoms and oxygen atoms, and different organic groups are linked to silicon atoms. The structure of silicone resin contains both "organic groups" and "inorganic structures". This special composition and molecular structure makes it a combination of organic properties and inorganic functions.

[0003] At present, in the process of using automatic feeding device in the production of silicone resin, if the feeding is not quantitatively performed, it will lead to over-feeding or under-feeding, thereby reducing the accuracy of the first feeding and the work quality.

[0004] For example, a feeding device for silicone resin production disclosed in Chinese patent publication number CN220990732U, in which the silicone resin enters the transport box through a transport pipe and falls onto the first slide, and an electronic flow meter measures the flow of the silicone resin. When the specified amount is reached, a command is sent to the electric valve, and the electric valve is closed; this avoids excessive or insufficient feeding due to inaccurate feeding, improves the accuracy of feeding, plays the role of quantitative feeding, and improves the work quality.

[0005] However, the electronic flow meter of the above device can only achieve the function of flow monitoring. When the flow reaches the threshold, the electric valve is controlled to close. During this process, the device cannot adjust the flow of silicone resin. Therefore, during the normal feeding process, if the flow exceeds the threshold, it cannot be adjusted accordingly. Only closing the electric valve will cause the feeding to proceed normally. Utility Model Content

[0008] The flow regulating module includes a rotating shaft that passes through the regulating box and rotates therein, and the rotating shaft is provided with an adjusting member consisting of a triangular plate, an extension plate and a connecting sleeve at the axis directly below the feeding module, the adjusting member is key-connected with the rotating shaft, and the rotating shaft is key-connected with the passive gear at the axis outside the regulating box; after the feeding module transmits the silicone resin, the rotating shaft drives the adjusting member consisting of the triangular plate, the extension plate and the connecting sleeve to rotate, so that after the resin unloading temporary storage area accumulates the fed silicone resin during the rotation process, when it rotates to the zero boundary point, after one of the resin unloading temporary storage areas completes the feeding, the other resin unloading temporary storage area accumulates the silicone resin again, thereby completing the secondary flow regulation of the silicone resin.

[0009] A further improvement of the technical solution of the utility model is that: the triangular plates are provided in multiple groups and the center array is welded to the connecting sleeve, two adjacent groups of the triangular plates form a temporary storage area for resin unloading, and each of the triangular plates is connected together by an extension plate.

[0010] A further improvement of the technical solution of the utility model is that: a driving gear is meshedly connected below the passive gear, and the driving gear is installed on a precision screw connected to a driving motor at the other end through a connecting key, and the precision screw rotates on the adjustment box and its threaded portion is threadedly connected to a moving sleeve, and the moving sleeve is fixedly connected to a moving block sliding on the rotating shaft through a connecting rod, and a torque sensor is installed on it; because the moving sleeve drives the torque sensor to move through the connecting rod, the torque sensor of the device is improved from a fixed type to a movable type, so in the selection of the torque sensor, firstly, the radio telemetry torque sensor does not need to contact the adjustment part, that is, the telemetry torque meter, and the specific model provided in this embodiment is ZHCKY, and secondly, if the radio telemetry torque sensor is affected by the silicone resin of the unloading material, the torque sensor moves to contact the adjustment part. This detection method uses the currently more mature strain electrical measurement technology, and during the rotation of the adjustment part, it continuously rubs against the contacting torque sensor.

[0013] A further improvement of the technical solution of the utility model is that a mounting plate is detachably mounted on the top cover, and a plurality of cylinders are arranged in a circle array in the inner center of the mounting plate, and a blocking pad for blocking a feed opening in the spherical part is arranged at the bottom of the cylinder.

[0014] Beneficial Effects

[0015] The utility model provides a feeding device for producing organic silicon resin. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The feeding device for the production of silicone resin accumulates the fed silicone resin in the resin feeding temporary storage area during the rotation through the flow regulating module. After the resin feeding temporary storage area completes the feeding, another resin feeding temporary storage area accumulates the silicone resin to complete the secondary flow regulation of the silicone resin. The feeding module is used to further realize the rapid regulation of the organic resin feeding flow, thereby avoiding the situation where the flow exceeds the threshold and cannot be adjusted, and avoiding the situation where the valve must be closed when the threshold is exceeded.

[0017] 2. The feeding device for the production of silicone resin completes the diversion of the silicone resin in the feeding pipeline through the feeding module.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-Figure 4 , this utility model provides 3 technical solutions:

[0036] Embodiment 1:

[0037] A feeding device for producing organic silicone resin, comprising a feeding tank 1, a feeding pipe 101a penetrating the inner wall of the feeding tank 1 is connected to one side of the feeding tank 1, a top cover 101b for sealing is arranged on the top of the feeding tank 1, a feeding module is arranged at the feeding channel inside the feeding tank 1, the feeding module is connected to a regulating box 2 arranged at the bottom of the feeding tank 1, and a flow regulating module for regulating is arranged in the regulating box 2;

[0038] The flow regulating module includes a rotating shaft 201a that passes through the regulating box 2 and rotates therein. The rotating shaft 201a is located at the axis directly below the feeding module and is provided with an adjusting member 201b composed of a triangular plate 201a-1, an extension plate 201a-2 and a connecting sleeve 201a-3. The adjusting member 201b is key-connected to the rotating shaft 201a, and the rotating shaft 201a is key-connected to the passive gear 201c at the external axis of the regulating box 2.

[0039] The present embodiment provides a flow regulating module for regulating the feeding flow of silicone resin. Specifically, after the feeding module transmits the silicone resin, the rotating shaft 201a drives the adjusting member 201b composed of the triangular plate 201a-1, the extension plate 201a-2 and the connecting sleeve 201a-3 to rotate. Therefore, after the resin unloading temporary storage area accumulates the fed silicone resin during the rotation process, when it rotates to the zero boundary point, after one of the resin unloading temporary storage areas completes the feeding, the other resin unloading temporary storage area accumulates the silicone resin again, thereby completing the secondary flow regulation of the silicone resin.

[0040] Embodiment 2:

[0041] On the basis of Example 1: multiple groups of triangular plates 201a-1 are provided and the center array is welded to the connecting sleeve 201a-3, two groups of adjacent triangular plates 201a-1 form a temporary storage area for resin unloading, and each triangular plate 201a-1 is connected together by an extension plate 201a-2.

[0042] The passive gear 201c is meshed with a driving gear 202a below, and the driving gear 202a is installed on a precision screw 202b whose other end is connected to a driving motor 202c through a connecting key. The precision screw 202b rotates on the adjusting box 2 and its threaded portion is threadedly connected to a movable sleeve 202b-1. The movable sleeve 202b-1 is fixedly connected to a movable block 202b-2 that slides on the rotating shaft 201a through a connecting rod 202b-4, and a torque sensor 202b-3 is installed on it.

[0043] In this embodiment, since the movable sleeve 202b-1 drives the torque sensor 202b-3 to move through the connecting rod 202b-4, the torque sensor 202b-3 of this device is improved from a fixed type to a movable type. Therefore, in the selection of the torque sensor 202b-3, firstly, the radio telemetry torque sensor does not need to contact the adjusting member 201b, that is, the telemetry torque meter. The specific model provided in this embodiment is ZH89-CKY-801. Secondly, if the radio telemetry torque sensor is affected by the silicone resin being unloaded, the torque sensor 202b-3 is moved to contact the adjusting member 201b. This detection method uses the relatively mature strain electrical measurement technology at present, and during the rotation of the adjusting member 201b, it constantly rubs against the contacting torque sensor 202b-3. Therefore, in the attached figure of this embodiment, a circular conductive slip ring is set at one end of the torque sensor 202b-3 close to the adjusting member 201b to further improve the detection accuracy of the rotation speed of the adjusting member 201b and reduce friction.

[0044] The bottom of the regulating box 2 is symmetrically provided with material delivery pipelines 203a, and the material delivery pipelines 203a are each provided with a control valve 203b for controlling material discharge.

[0045] Embodiment three:

[0046] On the basis of Example 1 and Example 2: the feeding module includes a spherical member 301 located in the feeding tank 1, and a plurality of groups of discharge ports 301a are arranged in an array on the spherical member 301. The spherical member 301 is limited to the conical port at the bottom of the feeding tank 1 by a sealing bearing seat 301b arranged at the bottom.

[0047] A mounting plate 302 is detachably mounted on the top cover 101 b , and a plurality of cylinders 303 are arranged in an array in the inner circle of the mounting plate 302 . A blocking pad 303 a for blocking the feed opening 301 a in the spherical member 301 is disposed at the bottom of the cylinder 303 .

[0048] In the present embodiment, the function of the spherical member 301 is to divert the silicone resin in the material delivery pipe 203a. Therefore, the spherical member 301 performs a buffering effect on the silicone resin in the middle, and cooperates with the blocking pad 303a matching the upper and lower feeding ports 301a of the spherical member 301 to complete the selective blocking of the material discharge, complete the initial flow regulation of the organic resin feeding, and avoid excessive silicone resin directly entering the regulating box 2, resulting in excessive flow exceeding the threshold.

[0049] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0050] During use, after the silicone resin is fed into the feeding tank 1 through the feeding pipe 101a, the silicone resin then flows down through the feeding tank 1 and finally flows down through the feeding port 301a of the spherical member 301. At this time, according to the selective start-up of the cylinder 303, the cylinder 303 is extended to drive the bottom blocking pad 303a to selectively block several feeding ports 301a to prevent excessive silicone resin from directly entering the regulating box 2, resulting in excessive flow exceeding the threshold. After the silicone resin enters the regulating box 2, the rotating shaft 201a drives the regulating member 201b composed of the triangular plate 201a-1, the extension plate 201a-2 and the connecting sleeve 201a-3 to rotate. Therefore, after the resin feeding temporary storage area accumulates the fed silicone resin during the rotation process, when it rotates to the zero boundary point, after one of the resin feeding temporary storage areas completes the feeding, the other resin feeding temporary storage area accumulates the silicone resin again, thereby completing the secondary flow regulation of the silicone resin.
