Description

Technical Field

[0001] This utility model relates to the field of resin production, and in particular to a quick-change automatic filling device for polyester resin. Background Technology

[0002] Polyester resin (including unsaturated and saturated polyester resins) is a basic raw material for industries such as coatings, adhesives, and composite materials. It is a medium-to-high viscosity liquid at room temperature and possesses characteristics such as flammability, volatility, crystallization, and hygroscopicity. Therefore, its final packaging stage places high demands on filling accuracy, operating environment, and automation. Currently, automatic polyester resin filling machines suffer from the following problems: limited nozzle design. Existing automatic filling machines initially used fixed nozzles designed to accommodate small-diameter packaging containers. When switching to larger-diameter containers, it is impossible to replace the nozzle with a matching tube diameter, resulting in low filling efficiency.

[0003] Therefore, there is an urgent need for a quick-change automatic polyester resin filling device that can improve filling efficiency. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0025] Example

[0026] This embodiment provides a quick-change automatic polyester resin filling device, including: a fixing component 1 and a filling gun assembly 2 detachably connected to the fixing component 1;

[0027] The fixing component 1 includes a cylinder 11, an upper clamp assembly 12, a lower clamp assembly 13, and a fixing block 14. The output end of the cylinder 11 is connected to the top end of the upper clamp assembly 12, driving the upper clamp assembly 12 to perform linear reciprocating motion and controlling the opening and closing of the filling process. The bottom end of the upper clamp assembly 12 is provided with a plurality of limiting posts 121, which are equidistantly arranged and form a pull rod placement cavity. The lower clamp assembly 13 includes a first clamp piece and a second clamp piece. One end of the first clamp piece is hinged to one end of the second clamp piece. The other end of the first clamp piece and the other end of the second clamp piece are detachably connected by bolts.

[0028] The filling gun assembly 2 includes: a gun body 21, a pull rod 22 sleeved on the gun body 21, a valve core 23 located at the bottom end of the pull rod 22, and a sealing part 24 located at the top end of the gun body 21; the side wall of the gun body 21 is provided with a feed inlet 211, and the bottom end of the gun body 21 is provided with a discharge outlet; the top end of the pull rod 22 is provided with a limiting block 221, which is located in the pull rod placement cavity and cooperates with a plurality of limiting posts 121 to achieve limiting; the upper clamp assembly 12 is connected to the top end of the pull rod 22, and the lower clamp assembly 13 is connected to the top end of the gun body 21; the valve core 23 is spindle-shaped, the outer diameter of the middle part of the valve core 23 is larger than the inner diameter of the discharge outlet, and the middle part of the valve core 23 is located outside the gun body 21.

[0029] When using it, the operator selects the appropriate size according to the diameter of the packaging container (e.g., The filling gun assembly 2 is assembled by inserting the limiting block 221 at the top of the pull rod 22 into the pull rod placement cavity of the upper clamp assembly 12. The limiting post 121 supports the limiting block 221, thus longitudinally limiting the filling gun assembly 2. The lower clamp assembly 13 clamps the top of the gun body 21. By adjusting the degree of engagement of the first clamp piece and the second clamp piece, it can adapt to multiple sizes of filling gun assemblies 2, thereby achieving lateral limiting of the filling gun assembly 2. If the filling gun assembly 2 needs to be replaced, simply open the lower clamp assembly 13 to replace the filling gun assembly 2. Remove the gun assembly 2 and install the new filling gun assembly according to the above installation steps; after the filling gun assembly 2 is installed, the operator controls the cylinder 11 to drive the upper clamp assembly 12 to move up and down linearly. The upper clamp assembly 12 drives the pull rod 22 to move up and down linearly. When the pull rod moves down, the valve core 23 moves down, and the resin flows out from the outlet for filling; after filling is completed, the operator controls the cylinder to pull the pull rod up, and the valve core 23 blocks the outlet, so that the resin cannot flow out.

[0030] In summary, this utility model provides lateral and longitudinal limits for the filling gun assembly by setting an upper clamp assembly and a lower clamp assembly. This ensures that the filling gun assembly is firmly assembled and also enables quick replacement of the filling gun assembly, thereby improving filling efficiency. The valve core is located outside the gun body and the filling is opened by pushing the valve core outward. After filling, the valve core will not retract into the gun body, which facilitates the cleaning of the filling gun assembly.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
