Description

Technical Field

[0001] The invention belongs to the field of glue spraying equipment, and in particular relates to glue spraying equipment which can rotate 360 ​​degrees. Background Art

[0002] In a traditional glue spray gun, the gun body is connected to a hot fluid heating and insulation block. When the needle valve piston rises, the fluid is directly ejected vertically from the channel in the lower cover of the gun, or an L-shaped nozzle is installed to fix the fluid to spray in a side direction. When it is necessary to spray the fluid on the inner or outer periphery of a square box or a round tank, the entire gun body together with the heating part and the fluid insulation heating pipe, solenoid valve, solenoid valve control line, air pipe, etc. need to be rotated together. Due to the limitations of the volume and dead weight of various pipelines and spray guns, the traditional spray structure cannot be rotated in a circular cycle for multiple times, and it is also difficult to rotate the entire structure within a small radius, resulting in poor spraying effect and failure to meet market demand.

[0003] In order to solve the above problems, Chinese patent CN109351511A discloses a rotatable spray gun and a hot melt glue spray gun thereof. The rotatable spray gun includes a mounting seat, a glue spraying device and a driving device. The glue spraying device is rotatably arranged in the mounting seat. The driving device includes a motor, which cooperates with a first gear; a second gear to drive the sleeve to rotate and then drive the sleeve to rotate so that the nozzle rotates. The method of driving the nozzle to rotate by cooperating with the motor and the gear is complex in structure, and the rotation angle control accuracy is not high, which needs further improvement.

[0012] Furthermore, the third cavity comprises a buffer section and a glue outlet section which are connected in sequence up and down, the glue inlet is opposite to the buffer section, and the piston rod can move downward to its lower end to close the upper end of the glue outlet section.

[0013] Furthermore, it also includes an air seal arranged between the outer periphery of the glue gun body and the inner wall of the rotating chamber for limiting the sealing of the transition air cavity, and the glue gun body is provided with an air inlet connecting the transition air cavity and the first cavity; the air seal includes two air seal rings which are relatively sleeved on the outer periphery of the glue gun body in upper and lower directions, and the transition air cavity is arranged between the two air seal rings.

[0016] Furthermore, it also includes a glue filter arranged in the second seat body, and the second seat body is provided with a second installation groove connected to the glue inlet channel for installing the glue filter.

[0017] Furthermore, the width of the support ring is smaller than the width of the openings of the first rubber sealing ring and the second rubber sealing ring.

The glue gun body 21 can be rotatably arranged in the rotating chamber 16, including a liquid glue containing chamber 211 formed inside the glue gun body and connected with the transition glue chamber 17 and the transition air chamber 18 respectively, an atomizing chamber 212 formed inside the glue gun body and connected with the transition atomizing chamber 19, a glue inlet 213 and an air inlet 214 connecting the containing chamber 211 and the rotating chamber 13, and a piston rod 215 which can be moved up and down in the containing chamber 211 to control the outflow of liquid glue; specifically, the glue gun body 21 can be rotatably arranged in the rotating chamber 13 through ball bearings 7 arranged opposite to each other up and down; the nozzle 22 is arranged on the side of the glue gun body 21, and is connected to the lower ends of the containing chamber 211 and the atomizing chamber 212.

[0032] The accommodating chamber 211 includes a first chamber 216 connected to the transition air chamber 18, a second chamber 217 connected to the bottom of the first chamber 216 for the piston rod 215 to move up and down, and a third chamber 218 connected to the bottom of the second chamber 217 for the liquid glue to flow out. The third chamber 218 includes a buffer section 2181 and a glue outlet section 2182 connected in sequence from top to bottom, and the glue inlet 213 is opposite to the buffer section 2181; specifically, the glue outlet section 2182 is L-shaped in the glue gun body 21; the atomizing chamber 212 is adjacent to the third chamber 218, and is L-shaped on the side of the third chamber 218.

[0033] The piston rod 215 can move up and down to its lower end to open or close the upper end of the glue outlet section 2182, including a floating block 2151 arranged in the first cavity 216 and a pin 2152 whose one end is connected to the floating block 2151 and the other end extends downward to the third cavity 218. Correspondingly, a sealing block 219 is arranged in the accommodating cavity 211, one end of the sealing block 219 is supported at the bottom of the first cavity 216 and the other end extends downward to the bottom of the second cavity 217. The floating block 2151 is arranged above the sealing block 219, and a gas control chamber 24 is formed between the floating block 2151 and the sealing block 219; the air inlet 214 is arranged on the glue gun body 21 at an angle downward and opposite to the gas control chamber 24; specifically, the sealing block 219 is formed with a through hole 2191 for the pin 2152 to pass through; when working, by controlling the amount of gas in the gas control chamber 24, the floating block 2151 moves up and down to drive the piston rod 215 to move up and down, thereby opening or closing the upper end of the glue outlet section 2182.

[0034] The glue seal 263 is arranged between the outer periphery of the glue gun body 21 and the inner wall of the rotating chamber 13 to limit the sealing performance of the transition glue chamber 17, including a first glue seal ring 231 which is sleeved on the outer periphery of the glue gun body 21 in a U-shape, a second glue seal ring 232 which is sleeved on the outer periphery of the glue gun body 21 and is located above the first glue seal ring 231 in an inverted U-shape, and a support ring 233 which is arranged between the first glue seal ring 231 and the second glue seal ring 232 and is opposite to the transition glue chamber 17. Accordingly, a step portion 131 which extends inwardly and is used to support the first glue seal ring 231 is formed on the inner wall of the rotating chamber 13; specifically, a plurality of make way holes 234 which connect the rotating chamber 13 and the transition glue chamber 17 are formed on the opposite surface of the support ring 233 and the transition glue chamber 17, and the width of the support ring 233 is smaller than the opening width of the first glue seal ring 231 and the second glue seal ring 232, so that the openings of the first glue seal ring 231 and the second glue seal ring 232 are also filled with liquid glue; when the glue outlet section 2 When the upper end of 182 is closed, the liquid glue remains stationary in the transition glue chamber 17 and the corresponding accommodating chamber 211. At this time, the first glue sealing ring 231 and the second glue sealing ring 232 are in sealing contact with the outer peripheral surface of the glue gun body 21; when the upper end of the glue outlet section 2182 is opened, the liquid glue flows through the transition glue chamber 17 and the rotating chamber 13 in sequence into the third cavity 218, so that the cross-sections of the first glue sealing ring 231 and the second glue sealing ring 232 are radially expanded, increasing the area for maintaining the sealing, and ensuring the sealing when the liquid glue flows; the first glue sealing ring 231 and the second glue sealing ring 232 are arranged opposite to each other up and down, which can ensure the sealing when the liquid glue flows. At the same time, a support ring 233 is arranged between the first glue sealing ring 231 and the second glue sealing ring 232 to separate the first glue sealing ring 231 from the second glue sealing ring 232, and at the same time, the second glue sealing ring 232 is supported to ensure the stability of the sealing between the first glue sealing ring 231 and the second glue sealing ring 232.

[0035] The air seal 3 is arranged between the outer periphery of the glue gun body 21 and the inner wall of the rotating chamber 13, and is used to limit the sealing of the transition air chamber 18. It includes two air seal rings 31 which are relatively sleeved on the outer periphery of the glue gun body 21 from top to bottom, and the transition air chamber 18 is arranged between the two air seal rings 31; specifically, the inner wall of the rotating chamber 13 extends outward to form a first installation groove 132 for installing the air seal ring 31, and the sealing of the transition air chamber 18 is ensured by the air seal rings 31 which are relatively arranged from top to bottom.

[0036] The driving device 4 is connected to and drives the glue gun body 21 to rotate in the rotating chamber 13, and includes a driving motor connected to the upper end of the glue gun body 21. The driving motor directly drives the glue gun body 21 to rotate. The driving method is simple and can accurately determine the rotation angle of the glue gun body 21 to meet production needs.

[0037] The glue filter 5 is arranged in the second seat body 12 to filter the liquid glue entering the transition glue chamber 17 through the glue inlet channel 14. Accordingly, the second seat body 12 is provided with a second installation groove 51 connected to the glue inlet channel 14 for installing the glue filter 5; specifically, the glue filter 5 is a filter commonly used for filtering liquid glue in glue spraying equipment, and its specific selection and working principle will not be further elaborated here.

[0038] The atomizing seal 6 is arranged between the outer periphery of the glue gun body 21 and the inner wall of the rotating chamber 13, and is used to limit the sealing of the transition atomizing chamber 19. It includes two atomizing seal rings 61 which are relatively sleeved on the outer periphery of the glue gun body 21 in upper and lower directions, and the transition atomizing chamber 19 is arranged between the two atomizing seal rings 61; specifically, the inner wall of the rotating chamber 13 extends outward to form a third mounting groove 133 for mounting the atomizing seal ring 61, and the sealing of the transition atomizing chamber 19 is ensured by the atomizing seal rings 133 which are relatively arranged in upper and lower directions; when spraying glue, it can be selected whether to introduce gas into the atomizing channel 16 according to the actual needs of liquid glue spraying, so as to atomize the liquid glue sprayed from the nozzle 22.

[0039] When the glue spraying device is in use, the lower end of the ejector pin 2152 closes the upper end of the glue outlet section 2182, and the liquid glue is filtered from the glue inlet channel 14 through the glue filter 5, flows into the transition glue chamber 17, and then enters the third cavity 218 through the clearance hole 234 and the glue inlet 213 to remain stationary; when spraying glue, the gas enters the gas control chamber 24 from the gas channel 15 through the transition gas chamber 18, so that the floating block 2151 moves upward to drive the ejector pin 2152 to move upward, and open the upper end of the glue outlet section 2182. At this time, the liquid glue in the buffer section 2181 flows downward through the glue outlet section 2182 to the nozzle 22 for liquid glue spraying; when spraying liquid glue, the drive motor can drive the glue gun body 21 to rotate to drive the nozzle to rotate 360°, so as to complete circular rotation spraying and obtain the desired spraying effect.

[0040] The present application defines the matching relationship between the glue gun body 21, the rotating chamber 13, the glue seal 23, and the air seal 3, so that the glue gun body 21 can be directly driven by the driving device 4 to perform multiple circular rotation spraying to obtain the desired spraying effect and meet the market demand; and the driving method of the glue gun body 21 is simple, the structural design is reasonable, and the required cost is low; at the same time, the first glue sealing ring 231 and the second glue sealing ring 232 are arranged relatively up and down to ensure the sealing of the transition glue chamber 17 and ensure the normal use of the glue spraying equipment.
