Limited glue taking device

Abstract

The utility model discloses a quantity-limited glue taking device which comprises a container used for storing an adhesive, a glue taking wheel used for dipping the adhesive in the container, a first rotary driver used for driving the glue taking wheel to rotate in a vertical plane, and a quantity limiter used for controlling the quantity of the adhesive remained at the upper part of the glue taking wheel. According to the quantity-limited glue taking device disclosed by the utility model, the glue taking wheel is used for dipping an adhesive in a container, and the quantity limiter is used for keeping the adhesive remained at the upper part of the glue taking wheel uniform and consistent, so that the quantity of the adhesive taken away from the upper part of the glue taking wheel by the transfer coater each time can be kept consistent; therefore, it can be guaranteed that the amount of the adhesive transferred to the packaging paper every time is uniform and consistent, the problem that the appearance of the packaging paper can be affected when too much adhesive is smeared is solved, and the problem that adhesion is not firm due to the fact that the smeared adhesive is insufficient can also be solved.

Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field, especially a kind of limited quantity glue taking device. BACKGROUND

[0002] Wrapping refers to the flexible material such as paper, plastic film, aluminum foil, composite film, which is used to cover the goods. The wrapping steps of rectangular goods include:

[0003] 1) Place the rectangular goods on a rectangular wrapping paper, then fold the wrapping paper from left and right sides (i.e. the two sides of the rectangular goods in the width direction) to cover the goods;

[0004] 2) Fold the wrapping paper at the end of the rectangular goods in the length direction inward to form an end sharp corner;

[0005] 3) Apply adhesive on the end sharp corner;

[0006] 4) Fold the sharp corner upward and paste it on the top.

[0007] In the prior art, the above-mentioned wrapping process of rectangular goods is completed by manual operation, and the production efficiency is low. To realize automatic wrapping, the technical problem of automatically applying adhesive to the wrapping paper needs to be solved. In addition, when applying adhesive, it is necessary to ensure that the amount of adhesive applied each time is uniform, otherwise, too much adhesive may affect the appearance of the package, and insufficient adhesive may cause poor adhesion. SUMMARY

[0008] Therefore, the utility model provides a limited quantity glue taking device to solve the technical problems of uniform and appropriate amount of adhesive taking and applying adhesive to the wrapping paper during the wrapping process of rectangular goods.

[0009] The limited quantity glue taking device of the utility model comprises a container for storing adhesive, a glue taking wheel for dipping adhesive in the container, a first rotary driver for driving the glue taking wheel to rotate in an upright plane, and a limiter for controlling the amount of adhesive remaining on the upper part of the glue taking wheel.

[0010] Further, the limiter is a scraper plate with adjustable distance from the glue taking wheel.

[0011] Further, the scraper plate is provided with an adjusting groove, and the scraper plate is fixed on the container by a screw arranged in the adjusting groove.

[0012] Further, the limited quantity glue taking device further comprises a transfer coater for transferring the adhesive on the upper part of the glue taking wheel to the wrapping paper.

[0013] Further, the transfer coater comprises a coating brush for dipping adhesive on the upper part of the glue taking wheel and a second rotary driver for driving the coating brush to swing up and down.

[0014] Further, the first and second rotary drivers are electric motors or pneumatic motors.

[0015] The present application has the following beneficial effects:

[0019] The present application will be further described in conjunction with the accompanying drawings and examples.

[0020] The present application has the following beneficial effects:

[0021] In the present application, the limiting device is a scraper 4 with adjustable distance from the glue taking wheel. The scraper is provided with an adjusting groove 5, and is fixed on the container by a screw 6 arranged in the adjusting groove. The position of the scraper can be adjusted by loosening the screw. Of course, in different embodiments, the scraper can also be installed on the container by other means, such as connecting a pressing plate to the container by a screw, and fixing the scraper by the pressing plate. The position of the scraper can be adjusted by loosening the pressing plate, and the position adjustment of the scraper is also convenient.

[0022] In the present application, the limiting device is a scraper 4 with adjustable distance from the glue taking wheel. The scraper is provided with an adjusting groove 5, and is fixed on the container by a screw 6 arranged in the adjusting groove. The position of the scraper can be adjusted by loosening the screw. Of course, in different embodiments, the scraper can also be installed on the container by other means, such as connecting a pressing plate to the container by a screw, and fixing the scraper by the pressing plate. The position of the scraper can be adjusted by loosening the pressing plate, and the position adjustment of the scraper is also convenient.

[0023] The first rotary driver and the second rotary driver described in the above embodiments can be electric motors or pneumatic motors.

[0024] Finally, it is to be explained that the above embodiments are merely used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
