Description

Technical Field

[0001] This utility model relates to the field of foam box sealing machine technology, and in particular to a scale calibration structure for a foam box sealing machine. Background Technology

[0002] The foam sealing machine is a high-efficiency packaging equipment designed specifically for sealing items that require cushioning protection. It automatically sprays foam material to form a soft and tightly adhered foam layer between the item and the carton, effectively absorbing vibrations and impacts during transportation and protecting the item from damage. The equipment is easy to operate, has a fast sealing speed, and can significantly improve packaging efficiency and reduce packaging costs. It is widely used in the packaging of fragile items such as electronic products and precision instruments.

[0003] When companies need to frequently change foam boxes of different sizes (such as electronic products, precision instruments, etc.), and the production batch of each size is small, the existing foam sealing equipment is not convenient for adjusting the size of the foam sealing machine according to the size of the foam box. In addition, the position of the foam box is prone to shift during the movement of the conveyor belt, which makes it difficult for the tape to stick well to the seal and also causes the seal position to shift, affecting the packaging effect of the foam box. Therefore, this utility model proposes a scale calibration structure for a foam box sealing machine to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a scale calibration structure for a foam box sealing machine, thereby solving the problem in the prior art where the position of the foam box easily shifts during the movement of the conveyor belt, affecting the packaging effect of the foam box.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a scale calibration structure for a foam box sealing machine, including a support platform, a conveying chamber and a connecting rod. The conveying chambers are symmetrically arranged on both sides of the top of the support platform. The conveying chambers are equipped with a conveying mechanism inside. The top of the support platform is fixedly connected to a support frame through the connecting rod. The inner side of the support frame is equipped with a support mechanism. The top of the support platform is equipped with a fixing mechanism. A grating reading head is installed on the conveying chamber and the support frame.

[0006] A further improvement is that the support mechanism includes rollers, bolts, and a sliding groove. The support frame has a sliding groove inside, and rollers are symmetrically arranged on both sides of the support frame. Bolts are symmetrically hinged on both sides of the rollers, and one end of each bolt passes through both sides of the sliding groove and is threaded with a nut.

[0007] A further improvement is that the fixing mechanism includes a lifting cylinder and a pressure plate. The two sides of the support platform are symmetrically and fixedly connected with lifting cylinders, and the output end of the lifting cylinder is fixedly connected with a pressure plate. The pressure plate is parallel to the position of the support frame vertically.

[0008] A further improvement is that a guide plate is fixedly connected to one side of the conveying chamber by bolts, one side of the guide plate is inclined outward, and the two guide plates form a trumpet-shaped structure.

[0009] A further improvement is that a limiting rod is fixedly connected to one side of the bottom of the support platform, one end of each of the two conveying chambers is slidably connected to both ends of the limiting rod, and a driving mechanism is provided on the other side of the bottom of the support platform.

[0010] A further improvement is that the driving mechanism includes a rotary motor and a bidirectional lead screw. The bidirectional lead screw is rotatably connected to the other side of the bottom of the support platform. The rotary motor is fixedly installed on one side of the support platform. The output end of the rotary motor is fixedly connected to one end of the bidirectional lead screw. The two ends of the bidirectional lead screw are respectively threaded to one end of the two conveying chambers.

[0011] A further improvement is that the conveying mechanism includes pulleys and belts, multiple pulleys are rotatably connected to the inner side of the conveying chamber, belts are sleeved on the outer sides of the multiple pulleys, and a drive motor is fixedly installed at the bottom of one side of the conveying chamber, with the output end of the drive motor fixedly connected to the bottom of one of the pulleys.

[0012] The beneficial effects of this utility model are as follows: Loosening the nuts on the bolts on both sides of the rollers prevents the nuts from clamping the bolts to the support frame, allowing the rollers to slide straight along the groove until the foam box is recessed between the two rollers, and the outer walls of the two rollers are respectively in contact with the two sides of the foam box. Then, tightening the nuts on the bolts locks the position of the rollers, which is used to support and limit the foam box. Depending on the size of the foam box, the nuts can be loosened again to adjust the position, so that it fits foam boxes of different sizes. This works in conjunction with the fixing mechanism to prevent the sealing position from shifting, which would affect the packaging effect of the foam box. Attached Figure Description

[0018] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a scale calibration structure for a foam box sealing machine, including a support platform 1, a conveying chamber 2, and a connecting rod 3. The conveying chambers 2 are symmetrically arranged on both sides of the top of the support platform 1. The conveying chamber 2 is equipped with a conveying mechanism inside. The top of the support platform 1 is fixedly connected to a support frame 4 through the connecting rod 3. The inner side of the support frame 4 is equipped with a support mechanism. The top of the support platform 1 is equipped with a fixing mechanism. A grating reading head 10 is installed on the conveying chamber 2 and the support frame 4. The foam box is placed on one side of the support platform 1, and the foam box is supported by the connecting rod 3 and the support frame 4. The conveying chamber 2 drives the foam box to move to the center of the support frame 4 through the conveying mechanism. The support mechanism inside the support frame 4 can adjust the position of its internal support components to fit various sizes of foam boxes. It works with the fixing mechanism to prevent the sealing position from shifting and affecting the packaging effect of the foam box.

[0020] The grating reading head 10 integrates a limit sensor internally and has a limit switch magnetic exciter externally. When the reading head moves along the grating main scale and approaches the end of its travel, the limit sensor senses the external limit switch magnetic exciter and triggers a sensing signal. This signal is transmitted to the control system, which then controls the reading head to stop moving to prevent it from colliding with both ends of the grating main scale and causing equipment damage. This limit mechanism achieves non-contact detection through magnetic induction. Combined with real-time signal transmission, it can efficiently ensure the safe operation and measurement accuracy of the grating system and improve the accuracy of limiting foam box sealing.

[0021] The support mechanism includes rollers 5, bolts 6, and grooves 7. The support frame 4 has grooves 7 inside, and rollers 5 are symmetrically arranged on both sides of the support frame 4. Bolts 6 are symmetrically hinged to both sides of the rollers 5. One end of each bolt 6 passes through both sides of the groove 7 and is threaded with a nut. Loosening the nuts on the bolts 6 on both sides of the rollers 5 will remove the clamping of the bolts 6 to the support frame 4, allowing the rollers 5 to slide linearly along the grooves 7 until the foam box is recessed between the two rollers 5, and the outer walls of the two rollers 5 are in contact with the sides of the foam box. Then, tightening the nuts on the bolts 6 locks the position of the rollers 5, which supports and limits the foam box. Depending on the size of the foam box, the nuts can be loosened again to adjust the position, making it fit various sizes of foam boxes. This works in conjunction with the fixing mechanism to prevent the sealing position from shifting, which would affect the packaging effect of the foam box.

[0022] The fixing mechanism includes a lifting cylinder 8 and a pressure plate 9. The lifting cylinder 8 is symmetrically fixedly connected to both sides of the support platform 1. The pressure plate 9 is fixedly connected to the output end of the lifting cylinder 8. The pressure plate 9 is parallel to the support frame 4 vertically. The pressure plate 9 and the output end of the lifting cylinder 8 are connected as one unit. The output end of the lifting cylinder 8 can drive the pressure plate 9 to move up and down reciprocally. The pressure plate 9 can press the unclosed foam box cover tightly when it moves downward, and then move upward to reset. The conveying bin 2 drives the foam box to the automatic tape wrapping equipment. The automatic tape wrapping equipment automatically wraps the tape at the connection between the box cover and the box body, and automatically packages the foam box cover.

[0023] One side of the conveying chamber 2 is fixedly connected to a guide plate 11 by bolts. One side of the guide plate 11 is inclined outward, and the two guide plates 11 form a horn-shaped structure. The guide plate 11 is fixed to one side of the conveying chamber 2 by bolts. The horn-shaped structure formed by the two guide plates 11 can guide the foam sealing box to move towards the middle of the support platform 1, and initially limit the position of the foam sealing box.

[0024] A limiting rod 13 is fixedly connected to one side of the bottom of the support platform 1. One end of each of the two conveying chambers 2 is slidably connected to both ends of the limiting rod 13. A driving mechanism is provided on the other side of the bottom of the support platform 1. The driving mechanism includes a rotary motor 12 and a bidirectional lead screw 16. The bidirectional lead screw 16 is rotatably connected to the other side of the bottom of the support platform 1. A rotary motor 12 is fixedly installed on one side of the support platform 1. The output end of the rotary motor 12 is fixedly connected to one end of the bidirectional lead screw 16. The two ends of the bidirectional lead screw 16 are threadedly connected to one end of each of the two conveying chambers 2. The limiting rod 13 can guide the movement trajectory of the conveying chambers 2. The bidirectional lead screw 16 is threadedly engaged with the conveying chambers 2. While the rotary motor 12 drives the bidirectional lead screw 16 to rotate in both directions, it can drive the two conveying chambers 2 to move in different directions simultaneously, thereby making the two conveying chambers 2 closer to or further away from each other. This allows the spacing between the two conveying chambers 2 to be adjusted according to the size of the foam sealing box. One side of each conveying chamber 2 is in contact with both sides of the foam sealing box.

[0025] The conveying mechanism includes pulleys 14 and belts 15. Multiple pulleys 14 are rotatably connected to the inner side of the conveying chamber 2, and belts 15 are sleeved on the outer side of the multiple pulleys 14. A drive motor is fixedly installed on the bottom of one side of the conveying chamber 2. The output end of the drive motor is fixedly connected to the bottom of one of the pulleys 14. The output end of the drive motor can drive one of the pulleys 14 to rotate. The belt 15 is sleeved on the outer side of the multiple pulleys 14. The multiple pulleys 14 and the belt 15 rub against each other and can drive them to rotate linearly back and forth. The belt 15 rubs against the outer side of the foam sealing box and can drive it to move in the direction of the belt 15's rotation.

[0026] The limiting structure of this foam sealing machine loosens the nuts on the bolts 6 on both sides of the roller 5, so the nuts no longer clamp the bolts 6 to the support frame 4. The roller 5 can slide linearly along the slide groove 7 until the foam box is recessed between the two rollers 5, and the outer walls of the two rollers 5 are respectively in contact with the two sides of the foam box. Then, the nuts on the bolts 6 are tightened to lock the position of the rollers 5, which is used to support and limit the foam box. Depending on the size of the foam box, the nuts can be loosened again to adjust the position so that it fits foam boxes of different sizes. In conjunction with the fixing mechanism, it prevents the sealing position from shifting, which would affect the packaging effect of the foam box.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
