DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means and specific purposes and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 8As shown, a seamless underwear gluing and bonding device with an electrostatic dust suction mechanism comprises a base plate 1, a dust removal device 2 arranged on the top of the base plate 1 for removing dust on the surface of the material, and a limiting mechanism 3 arranged on the base plate 1 for keeping the material level, the dust removal device 2 comprises a collecting box 21 fixed to the top of the base plate 1 for storing dust; a dust removal mechanism 24 capable of absorbing dust is horizontally arranged inside the collecting box 21; a moving frame 22 capable of horizontal movement is arranged on the top of the dust removal mechanism 24, and a cleaning brush 221 for cleaning the dust removal mechanism 24 is fixed on the lower end surface of the top of the moving frame 22; screw rods 231 capable of driving the moving frame 22 to move in the horizontal direction are arranged on both sides of the collecting box 21, and the moving frame 22 is threadedly connected to the screw rod 231; a first servo motor 23 for driving the screw rod 231 to rotate is arranged outside the collecting box 21.

[0027] When the first servo motor 23 drives the screw rod 231 to rotate, the screw rod 231 can effectively drive the moving frame 22 to move in the horizontal direction. The cleaning brush 221 provided at the bottom of the moving frame 22 can clean the surface of the dust removal mechanism 24, thereby avoiding the accumulation of dust on the dust removal mechanism 24. At the same time, when the cleaning brush 221 cleans the dust on the surface of the dust removal mechanism 24, the cleaned dust will fall into the collection box 21 below for storage. The effective maintenance of the dust removal mechanism 24 is achieved, ensuring the continuous and efficient operation of the dust removal mechanism 24 during the production process.

[0028] See also Figure 1 , Figure 3 and Figure 4 As shown, the limiting mechanism 3 includes a fixing frame 31 arranged near both sides of the collecting box 21, and the fixing frame 31 is fixed on the top of the bottom plate 1; a lower limiting roller 32 for lifting the material is arranged on the inner side of the limiting mechanism 3, and both ends of the lower limiting roller 32 are rotatably mounted on the fixing frame 31; a clearance groove 33 is arranged near the top of the fixing frame 31, and a slide bar 34 is longitudinally arranged at the center of the clearance groove 33, and an installation shaft 36 is slidably arranged on the outside of the slide bar 34, and a downward pressing roller 37 that can rotate and cooperate with the lower limiting roller 32 to clamp the material is arranged on the outside of the installation shaft 36; a spring 35 that can push the installation shaft 36 downward is arranged on the outside of the slide bar 34.

[0029] First, a fixing frame 31 is respectively provided on both sides close to the collecting box 21, and a lower limit roller 32 is arranged on the inner side of the fixing frame 31. The lower limit roller 32 lifts the bottom of the material to ensure that the material remains stable during the transmission process. Secondly, both ends of the mounting shaft 36 are slidably mounted on the slide bar 34. A rotatable lower pressure roller 37 is provided on the mounting shaft 36. A spring 35 is installed on the slide bar 34, and the elastic force of the spring 35 can push the mounting shaft 36 to move downward along the central axis direction of the slide bar 34. The lower pressure roller 37 can gradually approach the lower limit roller 32, so that the lower pressure roller 37 cooperates with the lower limit roller 32 to limit the material to a fixed height. The material is always in a relatively fixed position at the top of the dust removal device 2, and the lower surface of the material can be completely within the radiation range of the dust removal mechanism 24. In this way, the problem of unsatisfactory dust removal caused by the unstable position of the material in the dust removal mechanism 24 can be effectively avoided.

[0030] See also Figure 5 and Figure 6 As shown, the dust removal mechanism 24 includes an electrostatic dust removal rod 241 horizontally arranged inside the collecting box 21, and a control switch 242 for controlling the power supply of the electrostatic dust removal rod 241 is arranged outside the collecting box 21, and one end of the electrostatic dust removal rod 241 is electrically connected to the control switch 242.

[0031] During the material dust removal process, the control switch 242 energizes the electrostatic dust removal rod 241. At this time, a large number of positively charged radiation areas are generated around the electrostatic dust removal rod 241. When the material moves to the radiation area, the dust particles adsorbed on the material will be affected by the electrostatic effect. Specifically, these dust particles will be captured by the positive charge in the radiation area and then separated from the surface of the material. The dust removal operation of the material is realized, and the dust particles on the surface of the material are effectively removed.

[0032] See also Figure 5 and Figure 6 As shown, two sets of exhaust mechanisms 25 are arranged on the collection box 21, and the exhaust mechanism 25 includes a shell 251 fixed on two corresponding sides of the collection box 21, the input end of the shell 251 can extend to the inside of the collection box 21, and the inside of the shell 251 is provided with a fan 253 that can extract the air inside the collection box 21; the input end of the shell 251 is fixed with a fairing 255, and the inside of the fairing 255 is provided with an air filter element 256 for filtering dust particles in the air.

[0033] In order to prevent the cleaning brush 221 from causing dust to overflow during the dust removal process, a shell 251 is installed on two opposite sides of the collection box 21. A fan 253 is arranged inside the shell 251. When the fan 253 is started, the suction force generated by the fan 253 will extract the air inside the collection box 21 and discharge it through the output end of the shell 251. At this time, the air enters from the top of the collection box 21, flows downward through the inside of the collection box 21, and is then sucked out by the fan 253. The dust is effectively prevented from being raised when cleaning the dust removal mechanism 24, and the dust is prevented from being re-adsorbed on the surface of the material, thereby significantly improving the dust removal effect.

[0034] See also Figure 1 , Figure 2 and Figure 8 As shown, a heating mechanism 4 for heating the material is horizontally arranged near the center of the top of the base plate 1, and the heating mechanism 4 includes two groups of support seats 41 fixed on the top of the base plate 1, and a heater 42 capable of heating the material is arranged on the top of the support seat 41; a driving mechanism 43 for driving the heater 42 to move longitudinally is arranged on one side of the support seat 41.

[0035] In order to ensure that the heating plate at the bottom of the heater 42 maintains an appropriate distance from the material, a driving mechanism 43 is arranged on the side of the support seat 41. The working end of the driving mechanism 43 is hingedly arranged with the heater 42, so that the driving mechanism 43 can drive the heater 42 to move longitudinally. By adjusting the output of the driving mechanism 43, the distance between the heater 42 and the material can be controlled. The problem of material damage caused by the heating plate at the bottom of the heater 42 being too close to the material is effectively avoided, and the problem of unsatisfactory heating effect caused by the heating plate being too far away from the material is also solved. The appropriate distance between the heater 42 and the material is ensured, thereby optimizing the heating effect and protecting the material.

[0036] See also Figure 1 , Figure 2 and Figure 8 As shown, a plurality of connecting rods 421 are symmetrically arranged on two corresponding sides of the heater 42; the driving mechanism 43 includes two groups of first brackets 431 fixed to the sides of the support seat 41; a bidirectional threaded rod 433 is horizontally arranged on one side of the support seat 41, and both ends of the bidirectional threaded rod 433 are rotatably mounted on the first bracket 431, and one group of the first brackets 431 is provided with a second servo motor 432 for driving the bidirectional threaded rod 433 to rotate, and one end of the bidirectional threaded rod 433 can be fixedly connected to the output end of the second servo motor 432; the external threads of the bidirectional threaded rod 433 are connected with two groups of movable seats 434 that can move away from or approach each other, and the top of the movable seat 434 is hingedly provided with a support rod 436 for supporting the heater 42, and the end of the support rod 436 away from the movable seat 434 is hingedly arranged on the connecting rod 421.

[0037] When the height of the heater 42 is adjusted, the second servo motor 432 is started, and the second servo motor 432 drives the bidirectional threaded rod 433 to rotate. As the bidirectional threaded rod 433 rotates, the two groups of moving seats 434 installed on the bidirectional threaded rod 433 will approach each other or move away from each other. When the two groups of moving seats 434 move away from each other, the support rod 436 hinged on the top of each moving seat 434 will gradually tend to a vertical state. The support rod 436 drives the heater 42 upward. On the contrary, when the two groups of moving seats 434 approach each other, the support rod 436 set on the top of the moving seat 434 will gradually tend to a horizontal state. At this time, the support rod 436 will drive the heater 42 to move downward in the vertical direction. The longitudinal adjustment of the heater 42 is achieved, ensuring that the heater 42 and the material are kept at an appropriate distance.

[0038] See also Figure 1 As shown, a pressing table 5 capable of lifting the lower end surface of the material is fixed to one side of the top of the base plate 1 close to the heating mechanism 4, and a second bracket 50 is arranged on the top of the pressing table 5; a pressing plate 52 capable of longitudinally moving and pressing the material downward is arranged on the top of the pressing table 5, and a cylinder 51 for driving the pressing plate 52 to move longitudinally is symmetrically arranged on the top of the second bracket 50, and the top of the pressing plate 52 is fixedly connected to the output end of the cylinder 51.

[0039] When the material moves to the top of the pressing table 5, the output end of the cylinder 51 begins to extend downward and drives the pressing plate 52 downward until the pressing plate 52 presses on the upper end surface of the material. As the pressing plate 52 presses the material, the lower end surface of the material is in close contact with the pressing table 5. At this time, the pressing plate 52 and the pressing table 5 work together to form an effective pressing effect on the material, so that the material and the tape can be tightly bonded.

[0040] See also Figure 1 As shown, a material receiving rack 6 is arranged on one side of the top of the base plate 1 close to the pressing table 5, and a material receiving roller 61 for winding the material is horizontally arranged on the inner side of the material receiving rack 6. Both ends of the material receiving roller 61 are rotatably arranged on the material receiving rack 6, and a third servo motor 62 for driving the material receiving roller 61 to rotate is fixed to the side of one group of the material receiving racks 6, and one end of the material receiving roller 61 can be fixedly connected to the output end of the third servo motor 62.

[0041] When the third servo motor 62 is started, the third servo motor 62 drives the material receiving roller 61 to rotate. Not only can the material receiving roller 61 be wound up during the rotation, but also the material can be pulled by friction to achieve uniform feeding, thus ensuring the stability of the material during the winding process.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
