Description

Technical Field

[0001] The utility model relates to the technical field of latex powder packaging, in particular to a redispersible latex powder packaging device. Background Art

[0002] At present, the redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene / vinyl acetate copolymers, vinyl acetate / versatate copolymers, acrylic acid copolymers, etc. The powder adhesive is made after spray drying, and polyvinyl alcohol is used as a protective colloid. This powder can be quickly redispersed into an emulsion after contact with water. Since the redispersible latex powder has high bonding ability and unique properties, such as water resistance, construction performance and heat insulation, etc., its application range is extremely wide.

[0003] However, the existing latex powder is usually packaged manually, and the following disadvantages exist in the packaging process: the opening and closing of the feeding valve is manually controlled, so the weight of the latex powder loaded into each packaging bag is inconsistent and there is a large difference; at the same time, when the packaging is done manually, the bag mouth of the packaging bag is open, and the latex powder is easy to fly out of the bag mouth during the feeding process, resulting in waste of latex powder. Therefore, there is room for improvement. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-4 As shown, this embodiment provides a redispersible latex powder packaging device, including: a main body module 100 and a clamping module 200.

[0026] Among them, the main body module 100 includes a bracket 110, a hopper 120 installed on the bracket 110, a first electric valve 130 installed at the bottom of the hopper 120, an annular plate 140 fixed on the bracket 110, a weighing cylinder 150 arranged on the inner side of the annular plate 140, a mass sensor 160 installed in a circular array at the top of the annular plate 140 and connected to the weighing cylinder 150, and a second electric valve 170 installed at the bottom of the weighing cylinder 150.

[0027] The bracket 110 is used to install other components and maintain the stability of each component. The hopper 120 is used to fill latex powder to facilitate the delivery of the latex powder into the weighing cylinder 150. The first electric valve 130 is used to control the opening and closing of the hopper 120.

[0028] The annular plate 140 is fixed to the bracket 110 via a support rod and is used to install the mass sensor 160 to ensure the stability of the mass sensor 160 .

[0029] The weighing cylinder 150 is used to accurately weigh the latex powder loaded into the packaging bag, so as to ensure that the quality of the latex powder in each packaging bag is the same. The weighing cylinder 150 includes a cylinder body 151 arranged on the inner side of the annular plate 140, a support 152 fixed on the outer side of the cylinder body 151 in an annular array, and a discharge pipe 153 installed at the bottom end of the cylinder body 151. The cylinder body 151 serves as a weighing space for temporarily storing latex powder. The support 152 is fixed on the outer side of the cylinder body 151, and its bottom end is fixed to the top end of the mass sensor 160, which is used to transfer the quality of the latex powder in the cylinder body 151 to the mass sensor 160, so that the mass sensor 160 can monitor the quality changes of the latex powder in the cylinder body 151 in real time. The discharge pipe 153 is used to deliver the latex powder in the cylinder body 151.

[0030] The second electric valve 170 is installed on the discharge pipe 153 and is used to control the opening and closing of the discharge pipe 153 .

[0031] The clamping module 200 is installed on the bracket 110, and is used to clamp and close the bag opening of the packaging bag during packaging to prevent latex powder from flying out of the bag opening. It includes a first electric telescopic rod 210 symmetrically fixed on the bracket 110, an inner clamping plate 220 installed at the end of the first electric telescopic rod 210, a second electric telescopic rod 230 symmetrically fixed on the bracket 110, and an outer clamping plate 240 installed on the second electric telescopic rod 230.

[0032] The first electric telescopic rod 210 is used to install the inner clamping plate 220 and drive the inner clamping plate 220 to move. The second electric telescopic rod 230 is used to install the outer clamping plate 240 and drive the outer clamping plate 240 to move. In addition, the first electric telescopic rod 210 drives the inner clamping plate 220 to move in the direction of the outer clamping plate 240, and the second electric telescopic rod 230 drives the outer clamping plate 240 to move in the direction of the inner clamping plate 220. The cooperation of the two can make the inner clamping plate 220 and the outer clamping plate 240 move toward each other, so as to clamp and close the bag opening of the packaging bag.

[0033] Furthermore, grooves 221 are arranged in an array on the inner plate 220, and protrusions 241 are arranged in an array on the outer plate 240, and the protrusions 241 and the grooves 221 are interlocked with each other. Rubber pads are arranged on the relative outer sides of the inner plate 220 and the outer plate 240 to increase the friction between the inner plate 220 and the outer plate 240 and the packaging bag, so that the bag opening is closed more tightly.

[0034] The working principle and use process of the utility model are as follows: when in use, the mouth of the packaging bag is put on the outside of the discharge tube 153, the first electric telescopic rod 210 is extended, and the second electric telescopic rod 230 is retracted, which respectively drive the inner clamping plate 220 and the outer clamping plate 240 to move toward each other, clamp the mouth of the packaging bag, and keep the mouth of the packaging bag in a closed state. After that, the first electric valve 130 is opened, and the latex powder in the hopper 120 enters the inner cavity of the cylinder 151 from the bottom of the hopper 120. At this time, the mass sensor 160 weighs the mass of the latex powder in the cylinder 151, and when the mass of the latex powder in the cylinder 151 reaches the set weight, the first electric valve 130 is closed, and the second electric valve 170 is opened, so that the weighed latex powder in the cylinder 151 is sent to the packaging bag through the discharge tube 153, and the loading of the latex powder is completed.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
