DETAILED DESCRIPTION OF THE INVENTION

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0038] As Figures 1-5 shown, a plastic sheet brushing glue device for blister packaging flocking provided by the present invention includes: a processing platform 1, a brushing glue mechanism 4 arranged above the processing platform 1, a belt conveying mechanism 2 horizontally arranged at the upper end of the processing platform 1 and capable of intermittently conveying plastic sheets to the brushing glue mechanism 4, and a plurality of jigs 3 arranged at equal intervals on the belt conveying mechanism 2 and used for clamping plastic sheets.

[0039] The jig 3 includes: a box body 301, a clamping plate 302, and a clamping block 303; wherein,

[0040] A plurality of box bodies 301 with open tops are arranged at equal intervals on the belt 202 of the belt conveying mechanism 2 along its horizontal conveying direction, and two clamping plates 302 for clamping both sides of the plastic sheet are horizontally movably arranged at intervals inside each box body 301. Two clamping blocks 303 for clamping the remaining two sides of the plastic sheet are respectively arranged at intervals and movably on the opposite surfaces of the two clamping plates 302. Above the processing platform 1 beside the belt conveying mechanism 2, there is a brushing glue mechanism 4 capable of sequentially brushing glue on the plastic sheets in each jig 3 on the belt conveying mechanism 2.

[0041] In the above solution, during use, as Figures 1-5As shown in the figure, the plastic sheet with glue brushing is horizontally placed in each of the boxes 301 on the belt conveying mechanism 2. First, the two clamping plates 302 are respectively driven to approach each other until they abut against the plastic sheet, and then the two clamping blocks 302 on each clamping plate 302 are driven to approach each other along their length directions and abut against the plastic sheet, so as to clamp and fix plastic sheets of different sizes in the box 301. Then, the belt conveying mechanism 2 is driven to drive the belt 202 to intermittently convey the plastic sheet horizontally towards the glue brushing mechanism 4, so that the glue brushing mechanism 4 can brush glue on each plastic sheet. Since the belt conveying mechanism 4 can intermittently convey the plastic sheet to the glue brushing mechanism 4. When each plastic sheet on the belt conveying mechanism 2 moves to directly below the glue brushing mechanism 4, the operation of the belt conveying mechanism 4 is stopped, so that the glue brushing mechanism 4 can apply glue to the plastic sheet that has moved to directly below it. After the glue application is completed, the belt conveying mechanism 4 can be driven to operate again. During the process that the glue brushing mechanism 4 is brushing glue on the plastic sheet located directly below it, the staff can take away the other plastic sheets after glue brushing from the fixture 4 to complete the unloading operation, thus realizing the function of complementary interference between glue brushing and unloading, and greatly improving the working efficiency.

[0042] In addition, by respectively moving the two clamping plates 302 in the box 301 and the two clamping blocks 303 on each clamping plate 302, plastic sheets of different sizes horizontally placed in the box 301 can be clamped and fixed, so as to prevent the plastic sheet from moving in the box 301 during the glue brushing process and affecting the glue brushing effect. Thus, the practicability and flexibility of the whole device are improved.

[0043] In summary, through the combined use of the belt conveying mechanism 2 and the glue brushing mechanism 4 in the present invention, the function of complementary interference between glue brushing and unloading can be realized, thus greatly improving the working efficiency. And through a plurality of fixtures arranged on the belt conveying mechanism 2, plastic sheets of different sizes can be clamped and fixed, avoiding the movement of the plastic sheet during the glue brushing process and affecting the glue brushing effect, and improving the practicability and flexibility of the whole device.

[0044] In a preferred embodiment of the present invention, the device further includes a moving mechanism for driving the two clamping blocks 303 on each clamping plate 302 to move. The moving mechanism includes: an electromagnet 901, a magnetic block 902 and a spring 903; wherein,

[0045] In the middle of the upper end of each of the clamping plates 302, an electromagnet 901 is fixedly arranged. On each side of the electromagnet 901, the upper end of each of the clamping plates 302 is respectively recessed inward to form a moving groove, and a guide rod 10 is horizontally and fixedly arranged in each moving groove. A magnetic block 902 that can move along the length direction of the guide rod 10 and has a magnetic property opposite to that of the electromagnet 901 after passing through is slidably arranged on each guide rod 10. A part of each magnetic block 902 extends into the box body 301 at any time and a clamping block 303 is fixedly arranged. At the end of each guide rod 10 away from the electromagnet 901, a spring 903 is horizontally sleeved, and both ends of each spring 903 are respectively fixed on the magnetic block 902 and the moving groove.

[0046] In the above solution, the plastic sheet to be coated with glue is horizontally placed in the box body 301, and the two clamping plates 302 are respectively driven to approach each other until they abut against the plastic sheet. The two electromagnets 901 on the two clamping plates 302 are energized. After being energized, the two electromagnets 902 have magnetic properties opposite to those of the two corresponding magnetic blocks 902, so that a suction force is generated between each electromagnet 901 and the two corresponding magnetic blocks 902, thereby driving the two magnetic blocks 902 to approach each other until they abut against the plastic sheet. During the process of the two magnetic blocks 902 approaching each other, the corresponding springs 903 are stretched to make them in a stretched state. When the glue brushing is finished, the two clamping plates 302 are driven to move in the reverse direction away from the plastic sheet, and the electromagnets 901 on each clamping plate 302 are powered off. After being powered off, the electromagnets 901 lose their magnetism, and the attraction between each electromagnet 901 and the two corresponding magnetic blocks 902 disappears. During the process of the spring 903 restoring its initial state, each clamping block 902 can be driven to move in the reverse direction away from the plastic sheet, so that it is convenient for the staff to take the plastic sheet away from the box body 301.

[0047] In addition, on the outer walls of the two sides of the box body 301 corresponding to the two clamping plates 302, batteries for supplying power to the two electromagnets 901 are respectively fixedly arranged, and each battery is connected to the corresponding electromagnet 901 through an electric wire.

[0048] In a preferred embodiment of the present invention, the device further includes a screw rod 11 for driving the two clamping plates 302 to move; wherein,

[0049] Thread holes threadedly connected to the screw rod 11 are horizontally penetrated through the two side walls of each box body 301, and each screw rod 11 horizontally penetrates and is fixed on the side wall of the box body 301 through the thread holes, and the end of the screw rod 11 located inside the box body 301 is horizontally and rotatably arranged on the clamping plate 302.

[0050] In the above scheme, since the end of the screw rod 11 is rotatably connected to the corresponding clamping plate 302 , the clamping plate 302 can be pushed to move horizontally in the box body 301 during the process of rotating the screw rod 11 in both forward and reverse directions.

[0051] In addition, the screw rod 11 can be replaced by a servo electric cylinder. Specifically, the servo electric cylinder is horizontally penetrated and fixed on the side wall of the box body 301, and its telescopic end is fixed on the clamping plate 302. The servo electric cylinder drives the clamping plate 302 to move in the box body 301 to achieve the same function as the screw rod 11. The advantage of using it is that it replaces the manual rotation of the screw rod 11 to drive the clamping plate 302 to move, saving time and labor, and facilitating the function of quickly taking materials.

[0052] The servo electric cylinder is a well-known technical means, and its structure and use principle will not be repeated here. The servo electric cylinder is a modular product that integrates the servo motor and the lead screw. Its speed is 0.1-2m / s. Because of the closed-loop servo control, the control accuracy is high. It has the characteristics of low cost and flexible configuration, and is the best substitute for hydraulic cylinders and air cylinders.

[0054] Two pulleys 201 are spaced apart and horizontally rotatably provided at the upper end of the processing platform 1, and the two pulleys 201 are connected together through a belt 202, and a plurality of clamps 3 that can lean against the processing platform 1 are horizontally fixed at equal intervals on the belt 202 facing away from the pulleys 201 through fixed blocks 203.

[0055] In a preferred embodiment of the present invention, the device further comprises a driving mechanism 8 for driving the belt conveying mechanism 2 to intermittently convey the plastic sheet toward the glue brushing mechanism 4, wherein the driving mechanism 8 comprises: a conveying motor, an incomplete gear and a conveying gear; wherein,

[0057] In the above solution, during use, the conveyor motor is started to drive the incomplete gear on its output shaft to rotate. During the rotation process, it can intermittently engage with the conveyor gear, thereby driving the belt 202 to run intermittently. The conveyor motor is a reduction motor. Each time the incomplete gear engages with the conveyor gear, the belt 202 runs once. During the process of its one-time operation, multiple teaching aids 3 on the belt 202 can be successively moved directly below the glue brushing mechanism 4.

[0058] In a preferred embodiment of the present invention, the glue brushing mechanism 4 includes: a glue brushing roller 401, a feeding roller 402, a pump body 403, and a feeding box 404; wherein,

[0059] Above the processing platform 1 beside the belt conveyor mechanism 2, two vertical plates are fixedly arranged at intervals and vertically. Between the two, a glue brushing roller 401 and a feeding roller 402 that can contact each other are rotatably arranged in sequence from bottom to top. The bottom of the glue brushing roller 401 can contact each plastic sheet on the belt conveyor mechanism 2. Above the feeding roller 402, a feeding box 404 is horizontally fixedly arranged between the two vertical plates. At the bottom end of the feeding box 404, a number of nozzles communicating with its interior are vertically fixedly arranged at equal intervals along the axial direction of the feeding roller 402. The input end of the pump body 403 extends into the colloid source, and its output end is fixedly connected to the top of the feeding box 404.

[0060] In the above solution, during use, the pump body 403 is started to transport the colloid into the feeding box 404 and finally spray it onto the feeding roller 402 through a number of nozzles. Then, the colloid on the surface of the feeding roller 402 is smeared on the glue brushing roller 401. Finally, the plastic sheet located below the glue brushing roller 401 is subjected to glue brushing treatment, and the colloid on the glue brushing roller 401 is smeared on the plastic sheet, thereby completing the glue brushing operation.

[0061] In a preferred embodiment of the present invention, the device further includes: a glue storage tank 5 for storing viscous colloid; wherein,

[0062] On the upper ends of the processing platform 1 on both sides of the belt conveyor mechanism 2, two support frames 6 are respectively vertically fixedly arranged.

And a power motor is horizontally and fixedly arranged on the vertical plate, and the output shaft of the power motor is coaxially connected with the end part of the glue brushing roller 401 or the feeding roller 402.

[0066] In the above solution, during use, the power motor is used to drive the rotation of the glue brushing roller 401 or the feeding roller 402 that is coaxially connected to it. Under the meshing action of the first gear and the second gear, the feeding roller 402 and the glue brushing roller 401 can be driven to rotate simultaneously. The glue brushing operation is completed by their combined use.
