[0010] A bearing is provided between the outer wall of the bottom of the connector and the inner wall of the top of the turbine lift, so as to enable the mounting frame to rotate in the horizontal direction.

[0011] The technical problem to be solved by the present utility model can also be achieved through the following technical solutions.

[0017] Compared with the prior art, the beneficial technical effects of the present utility model are:

[0018] (1) The mounting frame is installed on the base through a turbine lift. The turbine lift realizes the up and down movement of the mounting frame. The mounting frame is rotatably installed on the turbine lift to realize the horizontal movement. Moreover, the installation position of the mounting frame and the turbine lift is adjustable in the horizontal direction, thereby realizing the adjustment of the mounting frame and the heating glue bucket thereon in the x, y, and z axes, so as to adjust the glue dispensing height and position.

[0019] (2) An electric heating plate is provided inside the heating glue bucket. Through the electric heating plate, the PUR glue placed in the heating glue bucket can be heated, so as to carry out gravity-fed glue dispensing under normal pressure. Compared with the traditional high-pressure extrusion glue dispensing (glue discharging), the heating glue dispensing method will not cause extrusion and rupture of the glue packaging bag on the one hand, and on the other hand, it can also make the glue flow out completely without retention, and there is very little glue residue phenomenon. Therefore, whether it is from the perspective of use convenience or operability, it can achieve the effect of cost reduction and efficiency increase to varying degrees;

[0020] (3) The heating glue bucket installed on the mounting rack is specially used for heating PUR glue. The PUR glue itself has packaging. During the heating of the PUR glue with packaging by the heating glue bucket, since the heating glue bucket can be closed through an external cover, that is to say, a relatively closed environment is actually formed inside the heating glue bucket during the heating process, achieving the effect of sealed glue taking to a certain extent. When the packaging bag of the PUR glue is opened and glue is dispensed, the contact surface between the glue and the air can be minimized to the greatest extent, thus ensuring the quality of the glue;

[0021] (4) An anti-sticking coating is provided on the inner wall of the heating glue bucket, which can reduce the adhesion of the glue to the relatively hot inner wall of the glue bucket as much as possible, and its structural design is reasonable;

[0022] (5) A cover is configured on the heating glue bucket, and a jacking device is installed on the cover. Through the jacking device, pressure can be applied to the PUR glue packaging bag in the glue bucket to drain the glue in the PUR glue packaging bag;

[0023] (6) A manual pressure plate is also provided inside the heating glue bucket. When there is still a small amount of glue in the PUR glue packaging bag that has not been drained, the manual pressure plate can be held and pressed to drain the glue;

[0024] (7) The overall structure of this PUR glue dispenser is simple and compact, without the need to use additional hoses. After the glue is heated to the molten state, it can be directly discharged and participate in the glue color mixing operation, which is very convenient. Compared with the previous glue dispensers that cannot perform color mixing, the application scenario of this PUR glue dispenser is wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following further describes the specific technical solutions of the present invention with reference to the attached drawings, so as to facilitate those skilled in the art to further understand the present invention without restricting its rights.

[0031] Example 1, refer to Figures 1-3 , PUR glue dispenser, including;

[0032] Base 1, the base 1 is formed into a substantially plate-like structure, and its shape can be selected according to the use requirements. The turbine elevator 2 is installed on the top of the base 1. The turbine elevator 2 is a prior art, and its model and specifications can be selected according to the use requirements;

[0033] Mounting frame 3, the mounting frame 3 is formed into a substantially square frame structure. The bottom of the mounting frame 3 is rotatably installed on the top end of the turbine elevator 2, so that the mounting frame 3 is driven by the turbine elevator 2 to lift. An installation groove is opened at the top of the mounting frame 3. The installation groove is formed into a substantially square groove structure. One end of the installation groove is set as the installation end detachably connected to the top end of the turbine elevator 2, and the other end is set as the glue bucket installation end;

[0034] Heating glue bucket 4, the heating glue bucket 4 is formed into a substantially cylindrical structure, and it is detachably embedded in the glue bucket installation end of the installation groove. A heating module is provided in the heating glue bucket 4, and a glue outlet 5 is provided on the bottom wall of the heating glue bucket 4. The glue outlet 5 is a round hole;

[0035] A connector 6 is provided at the bottom of the mounting frame 3. The connector 6 can be a flange joint structure. The bottom socket of the connector 6 is inserted into the top wall of the turbine elevator 2;

[0036] A number of adjustment holes 7 that can be detachably connected to the connector 6 are opened at the installation end of the installation groove of the mounting frame 3, so as to adjust the horizontal position of the mounting frame 3. The adjustment holes 7 can be round holes, waist-shaped holes, or both at the same time;

[0037] A bearing 8 is provided between the outer wall of the bottom of the connector 6 and the inner wall of the top of the turbine elevator 2, so as to allow the mounting frame 3 to rotate in the horizontal direction;

[0038] The described heating module includes a controller 9 and an electric heating plate 15 electrically connected to the controller 9. The controller 9 is installed on the outer wall of the turbine elevator 2, and the electric heating plate 15 is located on the bottom wall of the heating glue bucket 4. The controller 9 drives the electric heating plate 15 to turn on or off, and its heating temperature can be selected according to the usage requirements, such as 170°C ± 20°C;

[0039] The heating module of the described heating glue bucket 4 is arranged on the bottom wall of the heating glue bucket 4 and around the glue outlet 5. The height of the top surface of the heating module is higher than the height of the top surface of the glue outlet 5. The setting of this height difference can enable the glue in a molten state in the heating glue bucket 4 to flow by gravity into the glue outlet 5 to a certain extent.

[0040] A control valve 10 for controlling the glue discharge of the glue outlet 5 is provided on the bottom surface of the heating glue bucket 4;

[0041] An anti-sticking coating is fixedly provided on the inner wall of the heating glue bucket 4. This anti-sticking coating can be Teflon or other coatings, and its specification type can be selected according to the usage requirements.

[0042] In order to drain the glue in the PUR glue packaging bag completely, a cover body 11 is provided on the top of the heating glue bucket 4, and a jack 12 is provided on the top of the cover body 11. The handle of the jack 12 is located on the top of the cover body 11, and the deep end of the jack 12 is located on the bottom of the cover body 11. When the glue in the PUR glue packaging bag is not drained completely, the jack 12 can be driven to apply pressure to the PUR glue in the heating glue bucket 4, so as to squeeze and discharge the glue in the PUR glue packaging bag;

[0043] In order to further drain the glue in the PUR glue packaging bag completely, a manual pressure plate 13 is also provided in the heating glue bucket 4. The manual pressure plate 13 can be formed into a disc-shaped structure. The top surface of the manual pressure plate 13 forms a pressing surface for pressing the PUR glue packaging bag. A handle 14 convenient for holding is fixedly provided on the top of the manual pressure plate 13. When the PUR glue in the PUR glue packaging bag is not drained completely, the handle 14 can be held by hand to press the PUR glue in the heating glue bucket 4, so as to discharge the glue by direct pressing.

[0044] When this PUR glue feeding machine is in use, first install the mounting frame 3 on the top of the turbine elevator 2 of the base 1, and adjust the position of the mounting frame 3. After adjustment, place the heating glue bucket 4 on the glue bucket mounting end of the mounting frame 3. After placing it, place the PUR glue that needs to be fed into the heating glue bucket 4, and cover the top of the PUR glue with the cover body 11. At this time, the heating module can be turned on, and the PUR glue in the heating glue bucket 4 can be heated through the heating module;

[0045] It should be noted that, in order to ensure that the PUR glue with packaging can smoothly flow out through the glue outlet 5 of the heated glue barrel 4 by its own weight, a small hole can be punctured in the PUR glue packaging bag before the PUR glue is heated, or when the heating starts, a sharp object can be used to puncture the PUR glue with packaging in the heated glue barrel 4 along the inside of the control valve 10, so as to form small holes on the surface of the PUR glue, so that the PUR glue in the molten state can flow out by itself;

[0046] In addition, when the glue in the PUR glue packaging bag may not be completely discharged, it can be directly squeezed by the lifter 12 or the manual pressure plate 13.

[0047] The benefits of using this PUR glue dispenser are:

[0048] (1) The mounting frame 3 and the heated glue barrel 4 thereon can be adjusted in the X / Y / Z axis direction, and the operating space is large;

[0049] (2) The heating glue barrel 4 has a built-in heating module, which heats the PUR glue at normal pressure. The glue flows by itself without any residue, making the operation more environmentally friendly and convenient.

[0050] (3) During the heating of the PUR glue, since the glue is heated in a relatively closed heating glue barrel 4, the contact area between the PUR glue and the air is small and the contact time is short, so it is easier to ensure the quality of the glue;

[0051] (4) An anti-stick coating is provided on the inner wall of the heated glue barrel 4 to minimize the adhesion between the glue liquid and the inner wall of the heated glue barrel;

[0052] (5) The control valve 10 can directly discharge the glue liquid downward by gravity. When a container such as a glue pot is placed under the control valve 10, the glue pot can be used for color mixing. In other words, the device can be used for both glue liquid color mixing and direct use, and the rubber hose is directly discarded, which has a wide range of usage scenarios.

[0053] (6) When the glue in the PUR glue packaging bag cannot be completely drained, it can be directly squeezed through the lifter 12 or the manual pressure plate 13 to avoid the problem of incomplete glue discharge. The structural design is reasonable.
