Description

Technical Field

[0001] The present invention relates to the technical field of carton packaging, and particularly to a multi-purpose carton pressing and shaping device. Background Art

[0002] After the factory completes the processing of products, it is usually necessary to seal the products in cartons for transportation. For the packaging of cartons, it is necessary to first fold the flaps on the front and back sides towards the center side of the carton, then fold the flaps on the left and right sides towards the center side of the carton, and finally seal the tape at the gap between the flaps on the left and right sides. In order to improve the packaging efficiency of cartons, a folder gluer is usually used, which can automatically fold and package the cartons. The folder gluer also adopts the above-mentioned packaging process. However, in the clothing industry or other light goods industries, due to the nature of the goods themselves, the goods are easily filled with air, resulting in an increase in the volume of the goods, and further resulting in the goods being too high. If a folder gluer is used at this time, it is easy to cause damage to the carton flaps or ineffective carton sealing. Summary of the Invention

[0003] In view of the technical problems of the prior art, the present invention provides a multi-purpose carton pressing and shaping device.

[0004] To solve the above technical problems, the present invention provides the following technical solutions:

[0005] A multi-purpose carton pressing and shaping device includes: a pushing device, an exhaust device, and a conveying device; the exhaust device is arranged on one side of the conveying device; the conveying device is used for conveying the carton to a position corresponding to the exhaust device; the exhaust device includes an exhaust plate, and the exhaust plate is in transmission connection with the pushing device; the pushing device is used for pushing the exhaust plate into the carton.

[0006] During actual operation, the carton carrying the goods is conveyed by the conveying device to a position corresponding to the exhaust device. At this time, the pushing device acts to push the exhaust plate into the carton, and then the goods in the carton are squeezed by the exhaust plate, so as to discharge the air in the goods. Thus, the volume of the goods is effectively reduced, and it is effectively prevented that the carton flaps are damaged or the carton cannot be effectively sealed due to the large volume of the goods such as clothing during carton sealing.

[0007] Further, the exhaust device further includes an extension device; the extension device includes an extension plate, and one end of the extension plate is swingably connected to the exhaust plate.

[0008] Further, the extension device further includes an extension cylinder; one end of the extension cylinder is swingably connected to the extension plate; the other end of the extension cylinder is swingably connected to the exhaust plate.

[0009] Further, the exhaust device further includes a buffer device; the buffer device includes a buffer cylinder, one end of the buffer cylinder is connected to the pushing device; the other end of the buffer cylinder is connected to the exhaust plate.

[0010] Further, the buffer device further includes a limiting structure; the limiting structure includes a limiting plate and a sliding rod; one end of the sleeve of the buffer cylinder is connected to the pushing device, and the other end of the sleeve is connected to the limiting plate; the piston rod of the buffer cylinder passes through the limiting plate and is connected to the exhaust plate; the sliding rod passes through the limiting plate and is connected to the exhaust plate.

[0011] Further, it further includes a telescopic device; the telescopic device is in transmission connection with the pushing device; the pushing device is further used to push the telescopic device to a position corresponding to the folding of the carton; the telescopic device corresponds to the front folding, rear folding, left folding, and right folding of the carton respectively; when the telescopic device extends or retracts, it can push the corresponding folding.

[0012] Further, the number of the telescopic devices is four, and the included angle between two adjacent telescopic devices is 90°.

[0013] Further, the telescopic device includes a telescopic cylinder and a pushing claw; one end of the telescopic cylinder is in transmission connection with the pushing device; the other end of the telescopic cylinder is connected to the pushing claw.

[0014] Further, the included angle between the pushing claws corresponding to the front folding and the rear folding and the telescopic cylinder is an obtuse angle; the included angle between the pushing claws corresponding to the left folding and the right folding and the telescopic cylinder is an acute angle.

[0015] Further, the conveying device further includes a touch switch and a lifting device; the touch switch is in transmission connection with the lifting device; the touch switch is electrically connected to the pushing device.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] By using the telescopic device, the folding position of the carton can be adjusted, so that the folding position of the carton meets the working requirements of the carton closing machine.

[0018] Through the angle setting between the pushing claw and the telescopic cylinder, when the telescopic cylinder acts, the folding can contact one side of the pushing claw instead of the tip of the pushing claw, thus effectively increasing the contact area between the folding and the pushing claw, and further effectively avoiding the damage of the folding caused by the action of the pushing claw.

[0019] Through the angle setting between the pushing claw and the telescopic cylinder, when the pushing claw descends to a position corresponding to the folding, the pushing claw is not likely to contact the folding, thus effectively avoiding the damage of the folding by the pushing claw.

[0020] The exhaust plate can exhaust air from goods that are easy to fill with air inside, such as clothing, so that the height of the goods in the carton is adapted to the height of the carton, facilitating the folding and sealing machine to seal the carton.

[0021] The extension device can adjust the area of the exhaust plate according to actual needs, enabling the exhaust plate to adapt to cartons of different sizes.

[0022] After the exhaust plate contacts the goods, the buffer device can buffer the movement of the exhaust plate to avoid damage to components caused by too fast movement speed of the exhaust plate.

[0023] The buffer cylinder can further pressurize the exhaust plate, thereby being able to further exhaust the air inside the goods. Description of the Drawings

Detailed Embodiment

[0030] The following are specific embodiments of the present invention in combination with the drawings, further describing the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] A multi - purpose carton pressing and shaping device includes: a pushing device 1, a plurality of telescopic devices 2, and a conveying device 3. The pushing device 1 can adopt a cylinder, and a mounting plate 11 is arranged on the pushing device 1, and the action direction of the pushing device 1 is perpendicular to the mounting plate 11.

[0032] The telescopic device 2 includes a telescopic air cylinder 21 and a pushing claw 22. One end of the telescopic air cylinder 21 is fixedly arranged on the side of the mounting plate 11 close to the pushing device 1, so as to be in transmission connection with the pushing device 1, and the other end of the telescopic air cylinder 21 is connected to the pushing claw 22. The number of the telescopic devices 2 is four, and the included angle between two adjacent telescopic air cylinders 21 is 90°, so that the four pushing claws 22 can respectively correspond to the front folding flap, the rear folding flap, the left folding flap and the right folding flap of the carton. Among them, the included angles between the pushing claws 22 corresponding to the front folding flap and the rear folding flap and the corresponding telescopic air cylinders 21 are obtuse angles. The included angles between the pushing claws 22 corresponding to the left folding flap and the right folding flap and the corresponding telescopic air cylinders 21 are acute angles.

[0033] The conveying device 3 includes a plurality of conveying rollers 31, a touch switch 32 and a lifting device 33. The centers of the conveying rollers 31 are located on the same straight line. The touch switch 32 is arranged between the conveying rollers 31, and the position of the touch switch 32 is adapted to the position of the pushing device 1, so that when the carton touches the touch switch 32, it just moves to the position corresponding to the pushing device 1. The touch switch 32 is in transmission connection with the lifting device 33, and the touch switch 32 can move in the vertical direction through the lifting device 33.

[0034] According to the corresponding relationship between the telescopic device 2 and the folding flaps, the telescopic device 2 can be divided into a front telescopic device, a rear telescopic device, a left telescopic device, and a right telescopic device. Before the cardboard box moves to the position corresponding to the pushing device 1, the pushing device 1 is in a retracted state. The front telescopic cylinder and the rear telescopic cylinder are in an extended state. The left telescopic cylinder and the right telescopic cylinder are in a retracted state. Under the action of the lifting device 33, the sensing part of the touch switch 32 protrudes from the conveying path of the conveying device 3. During actual operation, the conveying roller 31 rotates continuously, causing the cardboard box on the conveying roller 31 to move in the direction close to the pushing device 1. When the cardboard box touches the sensing part of the touch switch 32, the touch switch 32 will be triggered, indicating that the current cardboard box has moved to the position corresponding to the pushing device 1. At this time, the conveying roller 31 stops rotating. At the same time, the pushing device 1 acts, pushing the pushing mounting plate 11 and then pushing the telescopic device 2, causing the telescopic device 2 to move towards the side close to the cardboard box. After the action of the pushing device 1 is completed, the telescopic device 2 will move to the position corresponding to the folding flaps of the cardboard box. At this time, the front pushing claws and the rear pushing claws are located outside the cardboard box, and the left pushing claws and the right pushing claws are located inside the cardboard box. At this time, the left and right telescopic cylinders extend synchronously, so that the left and right folding flaps of the cardboard box are pushed towards the outside of the cardboard box through the left and right pushing claws. Subsequently, the front and rear telescopic cylinders retract synchronously, so that the front and rear folding flaps of the cardboard box are pushed towards the inside of the cardboard box through the front and rear pushing claws. Thus, the adjustment of the folding flap position is completed. After the folding flap position adjustment is completed, the lifting device 33 acts, causing the sensing part of the touch switch 32 to descend, so that the sensing part of the touch switch 32 no longer contacts the cardboard box. At this time, the conveying roller 31 rotates, and the cardboard box is input into the folder-gluer. Among them, taking the left pushing claw and the front pushing claw as examples respectively. The angle between the left pushing claw and the left telescopic cylinder is an acute angle. On the one hand, when the left pushing claw pushes the corresponding folding flap, the folding flap can contact one side of the pushing claw, effectively avoiding damage to the folding flap caused by the sharp part of the pushing claw contacting the folding flap. On the other hand, it can effectively avoid the left pushing claw conflicting with the corresponding folding flap during the process of the pushing device 1 pushing the left telescopic device to descend, resulting in damage to the folding flap. At the same time, since the initial state of the front telescopic cylinder is different from the initial state of the left telescopic cylinder, the angle between the front pushing claw and the front telescopic cylinder is an obtuse angle, but the technical effect it produces is the same as the above content, which will not be elaborated here. In summary, the present invention can automatically adjust the folding flap position of the cardboard box to a state suitable for the operation of the folder-gluer. On the one hand, it can effectively avoid damage to the cardboard box caused by the interference between the front folding flap and the side folding flaps during the operation of the folder-gluer. On the other hand, there is no need to arrange staff to adjust the folding flap position of the cardboard box at the existing folder-gluer equipment, thus saving human resources.

[0035] The present invention further includes an exhaust device 4. The exhaust device 4 includes an exhaust plate 41, an extension device 42, and a buffer device 43. The exhaust plate 41 is connected to one side of the mounting plate 11 away from the pushing device 1 through the buffer device 43, so that the exhaust plate 41 is in transmission connection with the pushing device 1.

[0036] The extension device 42 includes an extension plate 421 and an extension cylinder 422. One end of the extension plate 421 is swingably connected to the exhaust plate 41. One end of the extension cylinder 422 is swingably connected to the extension plate 421, and the other end of the extension cylinder 422 is swingably connected to the exhaust plate 41.

[0037] The buffer device 43 includes a buffer cylinder 431 and a limiting structure 432. The limiting structure 432 includes a limiting plate 4321 and a sliding rod 4322. One end of the sleeve 4311 of the buffer cylinder 431 is connected to the pushing device 1 through the mounting plate 11. The other end of the sleeve 4311 is connected to the limiting plate 4321. The piston rod 4312 of the buffer cylinder 431 passes through the limiting plate 4321 and is connected to the exhaust plate 41. One end of the sliding rod 4322 passes through the limiting plate 4321 and is connected to the exhaust plate 41.

[0038] The extension cylinder 422 is default in a retracted state, so that the extension plate 421 is perpendicular to the exhaust plate 41. During actual operation, when the cardboard box triggers the touch switch 32, the peripheral detection sensor detects the size of the cardboard box. If the size of the cardboard box is too large, the extension cylinder 422 extends, thereby pushing the extension plate 421 to swing, and then changing the state of the extension plate 421 from the original perpendicular state to the same plane as the exhaust plate 41, so as to expand the area of the exhaust plate 41. When the pushing device 1 pushes the telescopic device 2 to move towards the side close to the cardboard box, it will also synchronously drive the exhaust plate 41 to move towards the side close to the cardboard box. When the exhaust plate 41 contacts the goods in the cardboard box, under the action of the resistance exerted by the goods on the exhaust plate 41, it will cause the exhaust plate 41 to move towards the side close to the mounting plate 11, thereby pushing the piston rod 4312 to cause the buffer cylinder 431 to contract. At the same time, it drives the sliding rod 4322 to move towards the side close to the mounting plate 11. Thus, the movement of the exhaust plate 41 is buffered to avoid damage to components caused by the too-fast movement of the exhaust plate 41. Among them, through the cooperation of the sliding rod 4322 and the limiting plate 4321, the buffered movement of the exhaust plate 41 can be limited, and the uncontrollable movement of the exhaust plate 41 during buffering can be effectively avoided. At this time, the piston rod 4312 of the buffer cylinder 431 moves towards the direction close to the conveying device 3, thereby pushing the exhaust plate 41 to move towards the direction close to the conveying device 3, and then discharging the air in the goods through the exhaust plate 41. Thus, the present invention is applicable to the sealing and packaging of goods such as clothing that are easy to fill with air inside. By discharging the air in the goods, the height of the goods in the cardboard box can be adapted to the height of the cardboard box, so that the folding cover sealing device can work normally.

[0039] Among them, multiple groups of photoelectric sensors can be used as the peripheral detection sensors. The photoelectric sensors are arranged between the conveying rollers 31 so that the photoelectric sensors can normally sense the cartons. The size of the cartons is judged by counting the number of photoelectric sensors blocked by the cartons. The size of the cartons can also be sensed by setting up a vision sensing system.

[0040] It should be noted that the front, back, left, and right described in this article are related to the conveying direction of the cartons by the conveying device 3. The direction from "back" to "front" is the same as the conveying direction of the cartons. The direction from left to right is perpendicular to the conveying direction of the cartons.

[0041] It should be noted that the area of the exhaust plate 41 in the present invention is smaller than the cross-sectional area of the carton, and the telescopic device 2 only adjusts the positional relationship of the folding pages and does not seal the carton. Therefore, after the telescopic device 2 finishes adjusting the positional relationship of the folding pages, there is still a gap between the folding pages that allows the exhaust plate 41 to pass through, so that the device can be reset smoothly after processing a carton.

[0042] It should be noted that the content related to control described in this article, such as the sequence of actions of each component and the action duration, can be completed by the prior art and is not the focus of protection of the present invention, so it will not be elaborated here.

[0043] The specific embodiments described in this article are only examples to illustrate the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
