[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] In order to solve the technical problems in the background technology, the following melamine formaldehyde resin paper automatic feeding device is provided:

[0029] Combine Figures 1-6As shown, the automatic feeding device for melamine formaldehyde resin paper provided by the utility model includes a shell 2, a moving component 1 is fixedly installed at the bottom of the shell 2, a feeding port 21 and a discharge port 22 are respectively provided on both sides of the shell 2, a loading component 4 is fixedly installed on the top of the shell 2, a paper discharge component 9 is fixedly installed in the shell 2 at the position of the discharge port 22, a motor 3 is fixedly installed on the front of the shell 2, and the output end of the motor 3 is connected to the paper discharge component 9, a cleaning component 8 is docked and installed in the shell 2 above the paper discharge component 9, and a pressing component 6 is fixedly installed on the shell 2 above the loading component 4;

[0030] During this period, the device is moved to the working position by the moving component 1 and waits for the operation. The device can also be flexibly transferred according to the feeding requirements, which reduces the limitations during the operation. The paper materials are placed uniformly through the feeding port 21 and discharged through the discharging port 22 when being exported. The loading component 4 realizes the uniform carrying and placement of the paper materials, which can ensure the batch feeding operation of the device. The paper discharging component 9 uses the paper rubbing principle to realize the paper discharging operation, which can ensure the continuity of paper discharging and avoid the traditional one-time feeding, ensuring the reaction effect. Through the mutual cooperation of the paper discharging component 9 and the cleaning component 8, the device can clean the dust and impurities on the paper guide component while discharging paper, avoiding long-term operation resulting in a lot of dust and impurities remaining on the paper guide component, ensuring the paper feeding effect of the device and reducing manual cleaning. The stacked paper materials can be pressed by the pressing component 6 to ensure the stability of the paper materials during feeding.

[0031] The cleaning assembly 8 includes a first gear 81, a cleaning brush 82, and a second rotating shaft 83; the paper discharging assembly 9 includes a paper picking component 91 and a material guiding component 92. The material guiding component 92 is fixedly installed in the housing 2 at the material discharging port 22, and the paper picking component 91 is dockedly installed in the housing 2 above the material guiding component 92. The paper picking component 91 is equipped with an infrared transmitter 71, and an infrared receiver 7 is fixedly installed on the front side of the housing 2. The infrared receiver 7 cooperates with the infrared transmitter 71. A second rotating shaft 83 is dockedly installed in the housing 2 above the paper picking component 91, and the second rotating shaft 83 is equipped with a first gear 81 that is in transmission cooperation with the paper picking component 91, and a cleaning brush 82 is fixedly installed on the second rotating shaft 83;

[0032] During this period, the motor 3 drives the paper picking component 91 to rotate, and the paper picking component 91 uses its structural characteristics to push the paper material forward. The paper material brought out will be blocked by the rubber surface of the guide component 92, ensuring that the top paper material is guided out, and when the paper picking component 91 rotates, the first gear 81 will drive the second shaft 83 to rotate, thereby driving the cleaning brush 82 to rotate, and cleaning the paper picking surface of the paper picking component 91. When the paper picking component 91 rotates, the infrared transmitter 71 and the infrared receiver 7 will be intermittently sensed to ensure that the number of times the paper picking component 91 rotates one circle can be sensed, thereby realizing the synchronization of the number of paper guides of the paper picking component 91 and completing the counting operation of the paper guides of the paper picking component 91, so that personnel can grasp the delivery amount and delivery process of the device in real time, and facilitate personnel to prepare for loading.

[0033] Example 2

[0034] like Figure 1 and Figure 6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0035] In this embodiment, the mobile component 1 includes a base 11, a support frame 12, and running wheels 13. The base 11 is fixedly installed on the bottom of the shell 2, the support frame 12 is fixedly installed on the bottom of the base 11, and the four corners of the support frame 12 are fixedly installed with running wheels 13.

[0036] During this period, the base 11 and the support frame 12 cooperate with each other to support the shell 2, and the walking wheels 13 at the bottom of the support frame 12 can be used to assist the rapid movement and transfer of the device itself.

[0037] In this embodiment, a guide component 5 is fixedly installed in the shell 2 on one side of the paper discharge assembly 9. The guide component 5 includes a guide wheel 51 and a first rotating shaft 52. The first rotating shaft 52 is docked and installed inside the shell 2, and the guide wheel 51 is fixedly installed on the first rotating shaft 52.

[0038] The guide member 5 cooperates with the paper pickup member 91 to press the paper material to ensure the stability of the paper material during feeding.

[0039] When the paper pickup component 91 guides the topmost paper material, the paper material will be pulled, and at that time, the guide wheel 51 will be pulled by the paper material, and will drive the guide wheel 51 and the first rotating shaft 52 to rotate.

[0040] The loading assembly 4 includes a loading plate 41, an electric telescopic cylinder 42, a knob 43, a mounting seat 44, and an opposing screw rod 45. Four groups of electric telescopic cylinders 42 are fixedly installed on the top of the shell 2. The bottom of the electric telescopic cylinders 42 is jointly hoisted with the loading plate 41. A guide port 411 is provided on the loading plate 41. The mounting seat 44 is fixedly installed on the bottom of the loading plate 41, and opposing screw rods 45 are docked and installed between the mounting seats 44. The ends of the opposing screw rods 45 are docked and installed with knobs 43. A material blocking plate 46 is placed on the top of the loading plate 41, and the bottom of the material blocking plate 46 passes through the guide port 411 and is penetrated by the opposing screw rod 45.

[0041] During this period, the loading assembly 4 has two states: loading and loading;

[0042] When loading, the carrier plate 41 will drop to the lowest position, and the staff can place the stacked paper materials on the carrier plate 41 through the feeding port 21, and then start the electric telescopic cylinder 42 to rise;

[0043] When loading, the carrier plate 41 has entered the delivery state. During this period, as the paper materials are discharged, the paper materials will gradually decrease. At this time, the electric telescopic cylinder 42 can be started to rise slightly.

[0044] Example 3

[0045] like Figures 1-6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0046] In this embodiment, the paper pickup component 91 includes a third rotating shaft 911, a paper pickup roller 912, and a second gear 913. The third rotating shaft 911 is docked and installed in the shell body 2 above the material guide component 92. The second gear 913 engaged with the first gear 81 is fixedly installed on the third rotating shaft 911. The paper pickup roller 912 is fixedly installed at the middle position of the third rotating shaft 911, and the infrared transmitter 71 is fixedly installed on the back of the paper pickup roller 912.

[0047] During this time, the third rotating shaft 911 is driven to rotate by the motor 3, and the paper stock can be rubbed out by the rotation of the pickup roller 912. The top paper stock will be brought out by the force of the pickup roller 912, while the paper stock below will be blocked by the guide member 92.

[0048] Furthermore, when the third rotating shaft 911 rotates, the second gear 913 can be used to drive the first gear 81 to rotate synchronously.

[0049] In this embodiment, the material guide component 92 includes a first material guide seat body 921, a lower sleeve rod 922, a spring 923, an upper sleeve rod 924, and a second material guide seat body 925. The first material guide seat body 921 is fixedly installed in the shell body 2 at the discharge port 22, and the top of the first material guide seat body 921 is provided with a mounting port 9211. The interior of the first material guide seat body 921 is provided with a mounting chamber 9212. The interior of the mounting chamber 9212 is fixedly installed with the lower sleeve rod 922, and the upper sleeve rod 924 extending into the mounting port 9211 is docked and installed on the lower sleeve rod 922. The top of the upper sleeve rod 924 is jointly fixedly installed with the second material guide seat body 925. The second material guide seat body 925 cooperates with the paper pickup roller 912, and the lower sleeve rod 922 is sleeved with a spring 923.

[0050] By combining the above contents, the paper stock can be pulled out by the rotation of the pickup roller 912. The topmost paper stock will be pulled out by the force of the pickup roller 912, while the paper stock below will be blocked by the rubber surface on the top of the first material guide body 921 and the second material guide body 925, thereby causing the paper stock to be misaligned.

[0051] When the paper pickup wheel 912 rotates to the lowest point, it will press the second material guide seat body 925. At this time, the second material guide seat body 925 will use the spring 923 between the lower sleeve rod 922 and the upper sleeve rod 924 to enter a lowered state. When the paper pickup wheel 912 brings the paper out, the second material guide seat body 925 will reset again.

[0052] The pressing assembly 6 includes a strip 61, a pressing piece 62, a contact switch 63, a torsion spring 64, and a fourth rotating shaft 65. The fourth rotating shaft 65 is docked and installed in the shell 2 above the carrier plate 41. The torsion spring 64 is mounted on the fourth rotating shaft 65. The pressing piece 62 is fixedly installed at the middle position of the fourth rotating shaft 65. The strip 61 is fixedly installed on the front side of the shell 2, and a contact switch 63 that cooperates with each other is provided between the strip 61 and the pressing piece 62.

[0053] When feeding paper, it needs to be lifted to the working point. The way to do this is that the top of the paper comes into contact with the pressing piece 62, which causes the contact switch 63 between the pressing piece 62 and the strip 61 to come into contact. At this time, the electric telescopic cylinder 42 stops rising.

[0054] When the volume of the paper material decreases, the pressing piece 62 will be adjusted downward by the torsion spring 64. At this time, the contact switch 63 is separated, and the electric telescopic cylinder 42 can be started to rise again until it reaches the above-mentioned contact state, ensuring that the height of the paper material meets the delivery requirements.

[0055] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
