Description

Technical Field

[0001] This utility model relates to the field of adhesive removal machine technology, specifically to an automatic sand-removing mechanism and adhesive removal machine. Background Technology

[0002] In industrial production, glue is often used to bond and fix workpieces. After the workpieces are removed, the glue residue on their surfaces can cause great trouble for their recycling. Therefore, glue removal is necessary when recycling workpieces.

[0003] Heating is a common method for removing adhesive from workpieces. For example, Chinese utility model patent CN218108709U discloses a degumming machine. During degumming, the workpiece needs to be put into a drum, and the drum stirs and heats the workpiece to remove adhesive. In the actual degumming process, in order to ensure that the workpiece is heated evenly and to improve the degumming effect, sand needs to be put into the drum together with the workpiece. After degumming, the sand and workpiece are discharged together from the inlet / outlet of the drum. The discharged sand and workpiece are then screened, and the screened sand can be reused. Currently, all the steps of sand feeding, sand and workpiece separation, and sand reuse require manual operation, resulting in low automation and high labor intensity for workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic sand-drawing mechanism and a degumming machine for degumming, enabling automatic sand loading, separation of sand and workpieces, and reuse of sand, thereby reducing the labor intensity of workers.

[0005] On the one hand, this utility model provides an automatic sand-removing mechanism for a glue-removing machine, comprising:

[0006] A sand storage tank, wherein the top of the sand storage tank is provided with an opening and the bottom of the sand storage tank is inclined;

[0007] A sieve disc, placed on the opening of the sand storage tank and connected below the inlet / outlet of the degumming machine, is used to screen the workpieces and sand discharged from the inlet / outlet; and,

[0008] A sand pumping machine is located on the lower side of the bottom of a sand storage tank and is used to pump sand from the sand storage tank into the drum of a degumming machine.

[0009] Furthermore, the screen disc is provided with outwardly protruding ridges around its perimeter, and the screen disc is supported on both sides of the opening of the sand storage tank by the ridges.

[0010] Furthermore, the sand storage tank is provided with a sand extraction chamber at the lower end near the bottom of the tank. The lower parts of the sand storage tank and the sand extraction chamber are connected by a communication port, and the input end of the sand extraction machine extends into the lower part of the sand extraction chamber.

[0011] Furthermore, the bottom of the sand-dredging chamber is lower than the connecting port, and the input end of the sand-dredging machine extends into the lower side of the connecting port.

[0012] Furthermore, the sand storage tank is equipped with an intercepting net that allows sand to pass through while preventing debris from entering the sand extraction chamber.

[0013] Furthermore, the intercepting net is inclinedly installed inside the sand storage tank, with the upper inclined end of the intercepting net extending above the connecting port and connected to the end wall of the sand storage tank, the lower inclined end of the intercepting net connected to the bottom of the sand storage tank, and the left and right sides of the intercepting net connected to the side walls of the left and right sides of the sand storage tank, respectively.

[0014] Furthermore, the sand dredging machine includes a sand dredging riser, a spiral shaft, a drive motor, and a sand discharge pipe;

[0015] The sand-draining riser is fixed on the sand-draining chamber. The lower end of the sand-draining riser extends into the lower part of the sand-draining chamber, and a sand inlet is provided on the side of the sand-draining riser near its lower end.

Detailed Implementation

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] like Figures 1-4 As shown in the figure, this utility model embodiment provides an automatic sand-draining mechanism for a degumming machine, including a sand storage tank 100, a screen plate 200, and a sand-draining machine 300.

[0033] The top of the sand storage tank 100 is provided with an opening, and the bottom of the sand storage tank 100 is inclined. The purpose of the inclined bottom of the sand storage tank 100 is to enable the sand to flow automatically from the higher end to the lower end.

[0034] The screen plate 200 is placed on the opening of the sand storage tank 100 and connected below the inlet / outlet 610 of the degumming machine. It is used to screen the workpieces and sand discharged from the inlet / outlet 610. The sand can pass through the screen plate 200, and the workpieces are trapped inside the screen plate 200.

[0035] Optionally, refer to Figure 1 and Figure 2 In order to facilitate the pouring of the workpieces collected in the screen plate 200, the screen plate 200 can be removed from the sand storage tank 100. In order to facilitate the installation and removal of the screen plate 200, the screen plate 200 is provided with an outwardly protruding flange 210 around it. The screen plate 200 is supported on both sides of the opening of the sand storage tank 100 by the flange 210.

[0036] The sand pumping machine 300 is located on the lower side of the bottom of the sand storage tank 100 and is used to pump sand from the sand storage tank 100 into the roller 620 of the degumming machine.

[0037] Optionally, refer to Figure 1 and Figure 2 The sand storage tank 100 is provided with a sand extraction chamber 400 at the lower end near the bottom of the tank. The lower part of the sand storage tank 100 and the sand extraction chamber 400 are connected by a connecting port 410. The input end of the sand pumping machine 300 extends into the lower part of the sand extraction chamber 400.

[0038] During sand pumping, the sand in the sand storage tank 100 can enter the sand pumping chamber 400 through the connecting port 410, and then be pumped into the roller 620 of the degumming machine by the sand pumping machine 300, thus achieving automatic sand loading.

[0039] In order to reduce the amount of sand remaining in the sand storage tank 100 and the sand pumping chamber 400 and improve the sand utilization rate, the bottom of the sand pumping chamber 400 is lower than the connecting port 410, and the input end of the sand pumping machine 300 extends into the lower side of the connecting port 410.

[0040] In some embodiments, refer to Figure 4 The sand dredging machine 300 includes a sand dredging riser 310, a spiral shaft 320, a drive motor 330, and a sand discharge pipe 340.

[0041] The sand-dredging riser 310 is fixed on the sand-dredging chamber 400. The lower end of the sand-dredging riser 310 extends into the lower part of the sand-dredging chamber 400, and the side of the sand-dredging riser 310 near its lower end is provided with a sand inlet 311. The upper end of the sand-dredging riser 310 extends out of the sand-dredging chamber 400 and upwards, and the side of the sand-dredging riser 310 near its upper end is provided with a sand outlet 312.

[0042] The spiral shaft 320 rotates to fit inside the sand-dredging riser 310.

[0043] The drive motor 330 is installed at the upper end of the sand-dredging riser 310 and is connected to the spiral shaft 320 for transmission. The drive motor 330 and the spiral shaft 320 can be driven by belts, chains and gears.

[0044] One end of the sand discharge pipe 340 is connected to the sand outlet 312 of the sand pumping riser 310, and the other end of the sand discharge pipe 340 extends obliquely downward into the inlet / outlet 610 of the degumming machine.

[0045] When the sand pumping machine 300 is feeding sand, the sand in the sand pumping chamber 400 enters the sand pumping riser 310 through the sand inlet 311. The drive motor 330 drives the spiral shaft 320 to rotate, lifting the sand entering the sand pumping riser 310 to the upper end. The sand lifted to the upper end of the sand pumping riser 310 enters the sand outlet 340 through the sand outlet 312, and then slides into the drum 620 of the degumming machine through the sand outlet 340.

[0046] It is understandable that, in addition to the spiral feeder with the structure described above, the sand dredging machine 300 can also use other types of feeders, such as vacuum feeders.

[0047] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 The sand storage tank 100 is equipped with an intercepting net 500 that allows sand to pass through and prevents debris from entering the sand pumping chamber 400.

[0048] Specifically, the interception net 500 is inclinedly installed inside the sand storage tank 100. The upper inclined end of the interception net 500 extends above the connecting port 410 and is connected to the end wall of the sand storage tank 100. The lower inclined end of the interception net 500 is connected to the bottom of the sand storage tank 100. The left and right sides of the interception net 500 are respectively connected to the side walls of the left and right sides of the sand storage tank 100.

[0049] By setting up an intercepting net 500 inside the sand storage tank 100, the intercepting net 500 can intercept large particles in the sand, preventing workpieces or other large particles from entering the sand pumping chamber 400. This can prevent workpieces or other large particles from entering the sand pumping machine 300 and causing damage to the sand pumping machine 300.

[0050] In some embodiments, continue to refer to Figure 1 , Figure 2 and Figure 3 The sand storage tank 100 is provided with a support leg 110 on the lower side near the higher end of the tank bottom, which can stably support the sand storage tank 100 on the installation platform.

[0051] Reference Figure 5 This utility model embodiment also provides a glue removal machine, including a glue removal machine body 600 and the above-mentioned glue removal machine automatic sand removal mechanism, which is installed on the glue removal machine body 600.

[0052] It is understood that integrating the automatic sand-removing mechanism of the adhesive remover onto the adhesive remover body 600 is an optional solution. In other embodiments, the automatic sand-removing mechanism and the adhesive remover can also be set separately.

[0053] When the aforementioned degumming machine is working, the sand pump 300 draws sand from the sand storage tank 100 into the degumming machine's drum 620 through the inlet / outlet 610. Simultaneously, the workpieces requiring degumming are manually placed into the drum 620. The drum 620 then stirs and heats the workpieces and sand to remove the degumming. After degumming, the drum 620 discharges the sand and workpieces from the inlet / outlet 610. The screen 200 catches the discharged sand and workpieces. The sand passes through the screen 200 and enters the sand storage tank 100, while the workpieces remain in the screen 200, thus separating the sand and workpieces. The sand entering the sand storage tank 100 can slide towards the lower side of the tank bottom, allowing the sand pump 300 to draw it back into the degumming machine's drum 620 for reuse during the next degumming operation. In summary, the degumming machine achieves automatic sand feeding, sand-workpiece separation, and sand reuse, thereby reducing the labor intensity of workers.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
