Description

Technical Field

[0001] This utility model relates to the field of cardboard explosion-proof technology, specifically to a cardboard box explosion-proof line device. Background Technology

[0002] In the production process of cardboard and cartons, poor forming and bursting lines often occur at the creases and forming points of cardboard and cartons due to reasons such as excessively short wood pulp fibers, production processes, and excessively low moisture content of the raw paper. This results in a lot of waste and increased costs. Currently, the methods used to prevent bursting lines in cardboard and cartons are mostly to increase the moisture content of the cardboard by spraying and humidifying the creases. However, general spray humidification methods are not convenient to automatically adjust the position according to the specifications of the cardboard and cartons, and are not convenient to automatically circulate the spray treatment.

[0003] Existing patent CN202323460171.6 discloses a cardboard box explosion-proof line device, including a supporting base plate, a supporting frame, a cardboard box explosion-proof line spraying mechanism, a circulating spraying assembly, a spray explosion-proof line assembly, and a cardboard box conveying mechanism. The cardboard box explosion-proof line spraying mechanism includes a fixed stand, a drive motor, a connecting rod sleeve, a rotating connecting rod, a rotating support, a telescopic spring, a sliding sleeve, a moving support rod, a support rod sleeve, a connecting support rod, a telescopic hydraulic rod, a spray gun, a water storage pump, and a water delivery hose. The cardboard box conveying mechanism includes a motor support plate, a rotary motor, an eccentric wheel, a support column, a spraying work platform, a platform shaft, a shaft support, a support spring, and a spring support plate.

[0004] In the actual implementation of the aforementioned patent, the distance between the two nozzles is adjusted by an electric actuator to adapt to the spraying position. However, during the spraying process, using only two nozzles results in uneven spraying, which affects the effectiveness of the explosion-proof line and makes it difficult to spray evenly onto cardboard boxes. Therefore, we propose a cardboard box explosion-proof line device. Utility Model Content

[0005] The purpose of this utility model is to provide a cardboard box explosion-proof line device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cardboard box explosion-proof line device, including a base, a support plate fixed to the top of the base, and a horizontal plate connected to the outer wall of the support plate;

[0007] A hollow rod runs through the top of the horizontal plate, and a water distribution pipe is fixedly connected to the tail end of the hollow rod. Multiple evenly distributed nozzles are fixedly connected to the bottom of the water distribution pipe. A driven gear is fixedly fitted on the upper side of the outer wall of the hollow rod. A driving gear meshes with the outer wall of the driven gear. The driving gear is fixed to the outer end of the drive shaft of the servo motor. The servo motor is fixed to the top of the horizontal plate.

[0008] By adopting the above technical solution, the device is fixedly installed at the place of use. When water spraying is required on cardboard boxes, water spraying can be performed through the nozzle at the bottom of the water distribution pipe. During the water spraying operation, the servo motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby rotating the water distribution pipe and the nozzle. This achieves uniform spraying of the cardboard boxes, which helps to improve the wetting effect of the cardboard boxes and thus improves the effect of the explosion-proof line.

[0009] In a preferred embodiment of this utility model, a liquid pump is fixedly installed on the upper side of one side wall of the support plate. One end of the liquid pump is fixedly connected to a water supply pipe, and the other end of the liquid pump is fixedly connected to a conduit. The outer end of the conduit is connected to a hollow rod through a rotary joint.

[0010] By adopting the above technical solution, when water is sprayed to wet the cardboard box, the liquid pump can draw water into the conduit, and then the conduit is used to guide the water into the hollow rod, so that the water can enter the water distribution pipe and thus achieve water supply.

[0011] In a preferred embodiment of this utility model, a sliding groove is provided on the other side wall of the support plate. A lead screw motor is fixed at the bottom of the inner cavity of the sliding groove. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the top of the inner cavity of the sliding groove. A suitable lead screw slider is fitted on the outer wall of the lead screw. The outer wall of the lead screw slider is fixedly connected to the cross plate.

[0012] By adopting the above technical solution, the lead screw is driven to rotate by the lead screw motor, which allows the lead screw slider to rise and fall along the height direction of the support plate. This, in turn, drives the water distribution pipe and the nozzle to adjust their height, thus adapting to cardboard boxes of different heights and ensuring that the water spray can get close to the cardboard box, thereby improving the accuracy of the water spray.

[0013] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0014] By adopting the above technical solution, the installation holes facilitate the installation and fixation of the entire device.

[0015] In a preferred embodiment of this utility model, a through hole is provided at the top of the horizontal plate corresponding to the hollow rod, and the hollow rod is rotatably connected to the inner wall of the through hole through a bearing.

[0016] By adopting the above technical solution, the stability of the hollow rod rotation is guaranteed.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The present application provides a cardboard box explosion-proof line device, which uses a liquid pump to draw water into a hollow rod and then sprays it onto the cardboard box through a nozzle at the bottom of the water distribution pipe to wet it. A servo motor drives the drive gear to rotate, which in turn drives the hollow rod to rotate, thereby rotating the water distribution pipe. This allows for uniform water spraying onto the cardboard box, which improves the uniformity of wetting and thus enhances the explosion-proof line effect of the cardboard box.

[0019] The lead screw is driven by a lead screw motor to rotate, which allows the lead screw slider to rise and fall along the height of the support plate. This, in turn, drives the water distribution pipe and the nozzle to adjust their height, thus adapting to cardboard boxes of different heights. This ensures that the water can be sprayed close to the cardboard box, thereby improving the accuracy of the water spray. Attached Figure Description

[0028] Please see Figure 1-3 This utility model provides a technical solution: a cardboard box explosion-proof line device, including a base 1, a support plate 2 fixed on the top of the base 1, and a horizontal plate 21 connected to the outer wall of the support plate 2;

[0029] A hollow rod 3 runs through the top of the horizontal plate 21. A water distribution pipe 31 is fixedly connected to the tail end of the hollow rod 3. Multiple evenly distributed nozzles 32 are fixedly connected to the bottom of the water distribution pipe 31. A driven gear 36 is fixedly mounted on the upper side of the outer wall of the hollow rod 3. A driving gear 37 meshes with the outer wall of the driven gear 36. The driving gear 37 is fixed to the outer end of the drive shaft of the servo motor 38. The servo motor 38 is fixed to the top of the horizontal plate 21.

[0030] It should be understood that in actual use, the device is fixedly installed at the place of use. When water spraying is required on the cardboard, water spraying can be performed through the nozzle 32 at the bottom of the water distribution pipe 31. During the water spraying operation, the servo motor 38 can drive the drive gear 37 to rotate, thereby driving the driven gear 36 to rotate, thus driving the water distribution pipe 31 and the nozzle 32 to rotate, thereby achieving uniform spraying of the cardboard, which helps to improve the wetting effect of the cardboard and thus improve the effect of the explosion-proof line.

[0031] Furthermore, mounting holes 11 are provided at the four corners of the top of the base 1. The mounting holes 11 facilitate the installation and fixation of the entire device.

[0032] Furthermore, a liquid pump 35 is fixedly installed on the upper side of one side wall of the support plate 2. One end of the liquid pump 35 is fixedly connected to a water supply pipe, and the other end of the liquid pump 35 is fixedly connected to a conduit 34. The outer end of the conduit 34 is connected to the hollow rod 3 through a rotary joint 33.

[0033] When water is sprayed to wet the cardboard box, the liquid pump 35 can draw water into the conduit 34, and then the conduit 34 guides the water into the hollow rod 3, so that the water can enter the water distribution pipe 31, thereby realizing water supply.

[0034] It is worth mentioning that a through hole is provided at the top of the horizontal plate 21 corresponding to the hollow rod 3. The hollow rod 3 is rotatably connected to the inner wall of the through hole through a bearing, thereby ensuring the stability of the rotation of the hollow rod 3.

[0035] like Figure 1 and 2 As shown in Figure 3; a sliding groove is provided on the other side wall of the support plate 2. A lead screw motor 22 is fixed at the bottom of the inner cavity of the sliding groove. A lead screw 23 is fixedly connected to the outer end of the drive shaft of the lead screw motor 22. The outer end of the lead screw 23 is rotatably connected to the top of the inner cavity of the sliding groove. A suitable lead screw slider 24 is fitted on the outer wall of the lead screw 23. The outer wall of the lead screw slider 24 is fixedly connected to the horizontal plate 21.

[0036] It should be understood that by driving the lead screw 23 to rotate through the lead screw motor 22, the lead screw slider 24 can be raised and lowered along the height direction of the support plate 2, which in turn can drive the water distribution pipe 31 and the nozzle 32 to adjust their height, thereby adapting to cardboard boxes of different heights, ensuring that the water can be sprayed close to the cardboard box, and thus improving the accuracy of water spraying.

[0037] The implementation principle of the explosion-proof line device for cardboard boxes in this application is as follows: The device is fixedly installed at the place of use. When water spraying treatment is required for cardboard boxes, the lead screw motor 22 drives the lead screw 23 to rotate, thereby enabling the lead screw slider 24 to rise and fall along the height direction of the support plate 2. This, in turn, drives the water distribution pipe 31 and the nozzle 32 to adjust their height so that they are close to the cardboard box. Then, the liquid pump 35 draws water into the conduit 34, which guides it into the hollow rod 3. Water is then sprayed through the nozzle 32 at the bottom of the water distribution pipe 31. During the water spraying operation, the servo motor 38 drives the drive gear 37 to rotate, which in turn drives the driven gear 36 to rotate. This causes the water distribution pipe 31 and the nozzle 32 to rotate, thereby achieving uniform spraying of the cardboard boxes, which helps to improve the wetting effect of the cardboard boxes and thus improves the explosion-proof line effect.
