Description

Technical Field

[0001] The invention belongs to the technical field of foam pad processing, in particular to a packaging device for foam pad production. Background Art

[0002] Foam pads are mostly made of foam plastics, which is a polymer material formed by a large number of gas micropores dispersed in solid plastics. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc. Its dielectric properties are better than those of the base resin. It has a wide range of uses. Almost all plastics can be made into foam plastics. Foam plastic molding has become an important field of plastic processing.

[0003] Since the production line output of foam pads is usually high, the packaging of foam pads is now done by machines, and the existing foam pads cannot be packed directly. Because the stacked foam pads are easily dispersed and misplaced during transportation, they need to be manually adjusted and then carried out, so packaging optimization work is also required.

[0008] Furthermore, the packing equipment includes a transfer base plate, the upper surface of the transfer base plate is evenly arranged with paper boxes, and the inside of the left paper box is evenly arranged with filling foam pads, the number of the pulling plate components is two, and the outer surface of the pulling plate component is fixedly connected to the outer surface of the vertical guide rail, and the transfer base plate also transports the paper boxes from right to left. The interior of each paper box is divided into three layers of areas, and three foam pads can be vertically inserted into each area.

[0009] Further, both sides of the single-side push plate are slidably connected to the left side of the inner cavity of the pull plate component through a slot, the front and rear sides of the matching push plate are slidably connected to the right side of the inner cavity of the pull plate component through a slot, and the inner wall of the matching slide plate is slidably connected to the right side of the inner wall of the vertical guide rail through a guide groove. The number of the integrated components is two, the axis of the outer control pulley is rotatably connected to the outer surface of the fitting stop shell through a connecting rod, the outer surface of the outer control pulley is slidably connected to the left side of the outer surface of the outer guide shell through a guide groove, and the outer surface of the fitting stop shell is slidably connected to the left side of the inner wall of the outer guide shell.

[0010] Furthermore, the sliding bellows includes a median partition, and hollow shell plates are symmetrically arranged on the upper and lower sides of the outer surface of the median partition, and a segmented slide plate is slidably connected to the side of the inner cavity of the hollow shell plate away from the median partition, and the side of the segmented slide plate away from the median partition is slidably connected to the inner wall of the groove transfer belt. There are two hollow shell plates, and the outer surface of the hollow shell plate is fixedly connected to the middle of the outer surface of the median partition, and the front and rear sides of the median partition are fixedly connected to the outer surface of the vertical rod through the side sleeve shell, and the bottom end of the lower pressure plate extends to the inside of the outer guide shell through the through-hole, and the median partition can synchronize with the upper lower pressure plate to perform vertical sliding movement, thereby driving the internal pressure of the hollow shell plates on the upper and lower sides to change.

[0011] Furthermore, the modified skateboard includes an oblique sliding shell, the top of the inner cavity of the oblique sliding shell is evenly provided with through nozzles, the inner cavity of the oblique sliding shell is evenly provided with auxiliary rollers, the front and rear sides of the axis of the auxiliary rollers are fixedly connected with built-in motors, the outer surface of the built-in motor is fixedly connected with a compression push rod through a bent connecting rod, the bottom end of the compression push rod is fixedly connected with a pressurizer, and the pressurizer pressurizes and sprays the inside of the oblique sliding shell and the compression push rod by absorbing external air.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can replace manual work to transport and pack the stacked foam pads, ensuring that the required number of foam pads can be evenly filled inside each paper box. After the foam pads are transported by the device, they are transferred from a flat state to a vertically plugged state, so that they can be quickly loaded into the paper box to complete the filling work. In addition, during transportation, it can be ensured that the stacked foam pads will not have relative misalignment problems, and manual adjustment work is not required, thus realizing fully automated shipping and packaging work, which is more automated and optimizes labor costs.

[0014] 2. When the device transports the foam pad, the foam pad will be blocked by the integration component after entering the inclined surface of the outer guide shell, and then the integration component guides the foam pad to slide down at a uniform speed, and transports the inclined foam pad to a vertical state, ensuring that the three stacked foam pads are not misaligned. At the same time, the clamped foam pad can be vertically placed into the paper box below through the push plates on both sides, and the clamping force on the foam pad is controlled by the sensor. While ensuring that the stacked foam pads will not loosen, the problem of excessive clamping force causing obvious clamping marks and damage to the foam pads can be avoided.

[0015] 3. Before the device transfers the foam pads to the inclined portion of the outer guide shell, the air between the stacked foam pads will be discharged through the lower pressure plate, so that the foam pads fit more tightly and the gaps between the foam pads are reduced. At the same time, the sliding bellows will drive the airflow through the notches of the slotted transfer belt, so that the airflow passes through the outer surface of the stacked foam pads, and the processed stacked foam pads are removed and cooled to avoid dust on the outer surface of the foam pads remaining inside the outer guide shell, causing the inner wall of the outer guide shell to be not smooth enough, resulting in the problem that the foam pads do not slide smoothly inside the device after a long time.

[0016] 4. After the oblique sliding shell of the device is modified, the foam pad that slides against the oblique sliding shell can be pushed by the auxiliary roller that pushes upward periodically, thereby preventing the foam pad from stagnating on the oblique sliding shell due to the rough outer surface. The auxiliary roller that rolls counterclockwise can give the foam pad an oblique downward thrust when it contacts the lower surface of the foam pad, thereby ensuring that the foam pad can move smoothly. At the same time, the air is ejected upward through the nozzle to offset the pressure of the foam pad against the oblique sliding shell, thereby reducing the friction between the oblique sliding shell and the foam pad, reducing the friction generated when the foam pad slides, and alleviating the wear of the foam pad.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] Example 1, please refer to Figure 1-Figure 7 The present invention provides a technical solution: a packaging device for foam pad production, comprising a plate transport device 1, a guide device 2 is arranged on the left side of the plate transport device 1, a packing device 3 is arranged at the bottom of the guide device 2, and the plate transport device 1 transports the stacked foam pads from right to left, usually three foam pads are stacked as a group for transportation;

[0029] The plate transporting device 1 comprises a support frame 11, the top of the support frame 11 is fixedly connected to a transfer motor 12 through a vertical plate, the outer surface of the output shaft of the transfer motor 12 is rotatably connected to a groove transfer belt 13 through a transmission shaft, a traction sleeve 14 is symmetrically arranged in the middle of the outer surface of the groove transfer belt 13, a lower pressure plate 15 is fixedly connected to the axis center of the inner wall of the traction sleeve 14 through a vertical rod, and a sliding bellows 16 is arranged inside the groove transfer belt 13;

[0030] The guiding device 2 includes an outer guide shell 21, and the outer guide shell 21 is symmetrically fixed with limited fixing rods 22 on the front and rear sides close to the plate transporting device 1. The left side of the inner wall of the outer guide shell 21 is slidably connected with an integrating component 5, and a modified slide plate 4 is provided at the bottom of the left side of the inner wall of the outer guide shell 21. The bottom end of the outer guide shell 21 is fixedly connected with a vertical guide rail 23, and the left side of the inner cavity of the vertical guide rail 23 is slidably connected with a single-sided push plate 25 through a penetrating push rod, and the right side of the inner cavity of the vertical guide rail 23 is slidably connected with a matching push plate 26 through a penetrating push rod, and the left side of the outer surface of the matching push plate 26 is fixedly connected with a matching slide plate 27 through a penetrating push rod, and the front and rear sides of the outer surface of the vertical guide rail 23 are symmetrically provided with pulling plate components 24.

[0031] The integrated component 5 includes a fitting baffle shell 51, the inner wall of which is fixedly connected with a sensor 52, the top of the sensor 52 is fixedly connected with a limiting top plate 53 through a transmission belt, the lower surface of the limiting top plate 53 is evenly provided with pressure push rods 54, and the back of the inner cavity of the sensor 52 is fixedly connected with an external control pulley 55. The stacked foam boards entering the left side of the outer guide shell 21 will slide down along the oblique modified skateboard 4, but the stacked foam boards at this time will inevitably be misplaced due to gravity factors, so the fitting baffle shells 51 on both sides are needed to block the stacked foam boards, and the synchronous stacked foam boards slide obliquely along the modified skateboard 4, and the misplaced stacked foam boards are integrated together in the process.

[0032] The packing equipment 3 includes a transfer base plate 31, the upper surface of which is evenly provided with paper boxes 32, and the interior of the left paper box 32 is evenly provided with filling foam pads 33. There are two pulling plate components 24, and the outer surface of the pulling plate component 24 is fixedly connected to the outer surface of the vertical guide rail 23. The transfer base plate 31 also transports the paper boxes 32 from right to left. The interior of each paper box 32 is divided into three layers, and three foam pads can be vertically inserted into each area.

[0033] Both sides of the single-side push plate 25 are slidably connected to the left side of the inner cavity of the pull plate component 24 through slots, the front and rear sides of the matching push plate 26 are slidably connected to the right side of the inner cavity of the pull plate component 24 through slots, and the inner wall of the matching slide plate 27 is slidably connected to the right side of the inner wall of the vertical guide rail 23 through a guide groove. There are two integrated components 5, the axis of the outer control pulley 55 is rotatably connected to the outer surface of the fitting stopper shell 51 through a connecting rod, the outer surface of the outer control pulley 55 is slidably connected to the left side of the outer surface of the outer guide shell 21 through a guide groove, and the outer surface of the fitting stopper shell 51 is slidably connected to the left side of the inner wall of the outer guide shell 21.

[0034] The device is used to package the foam pads. After the foam pads are stacked together in groups of three, they are placed on the right side of the grooved conveyor belt 13 and transferred from right to left under the control of the transfer motor 12. When passing through the lower pressure plate 15, the traction sleeves 14 on both sides drive the top lower pressure plate 15 to slide down, compacting and limiting the stacked foam pads. Then the foam pads enter the inclined area on the left side of the guide device 2 for transfer.

[0035] The three stacked foam pads slide down along the inclined surface of the outer guide shell 21 and the modified skateboard 4, and then their bottoms are blocked by the fitting stop shells 51 on both sides and limited by the limiting top plate 53 above. Then, the outer control pulley 55 slides obliquely downward along the slide groove on the left side of the outer guide shell 21, driving the stacked foam pads inside to move. In this process, the fitting stop shell 51 always presses against the lower surface of the foam pads to prevent the three foam pads from continuing to move relative to each other.

[0036] When the stop shell 51 moves to the vertical guide rail 23 below, the outer control pulley 55 is twisted to rotate the integrated component 5 from the inclined state to the vertical state, fitting the inner wall of the vertical guide rail 23. At this time, the bottom of the stop shell 51 lifts the bottom of the foam pad, and then the pull plate component 24 pushes the single-sided push plate 25 on the left to the right. At this time, the limiting top plate 53 in the vertical state slides to the right along the slide groove of the stop shell 51, pushing the foam pad in the vertical state to slide to the right. At this time, the right side of the foam pad fits with the matching slide plate 27. Therefore, the three foam pads are in a clamped state at this time, and then the pulling plate component 24 pulls the matching push plate 26 on the right to slide to the right, and then pushes the stacked foam pads to the right relative to the fitting baffle shell 51, and then the bottom of the foam pad is aligned with the empty area of ​​the paper box 32 directly below, and the pulling plate component 24 controls the push plates on both sides to release the clamped foam pads, and the foam pads are inserted into the interior of the paper box 32. According to the above method, after each paper box 32 is filled, the paper box 32 is transported through the transfer bottom plate 31 to complete the packing of the foam pads.

[0037] In the process of pushing the vertical limiting top plate 53 to slide to the right, since the limiting top plate 53 needs to clamp the foam pad together with the matching slide plate 27, the foam pad will press the pressed push rod 54 in the opposite direction, and then monitor the reaction pressure on the limiting top plate 53 through the sensor 52, so as to prevent the problem of the foam pad loosening.

[0038] Example 2, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of the first embodiment, the sliding bellows 16 comprises a middle partition 161, and hollow shell plates 162 are symmetrically arranged on the upper and lower sides of the outer surface of the middle partition 161, and a segmented slide plate 163 is slidably connected to the side of the inner cavity of the hollow shell plate 162 away from the middle partition 161, and the side of the segmented slide plate 163 away from the middle partition 161 is slidably connected to the inner wall of the groove transfer belt 13. There are two hollow shell plates 162, and the outer surface of the hollow shell plate 162 is fixedly connected to the middle of the outer surface of the middle partition 161, and the front and rear sides of the middle partition 161 are fixedly connected to the outer surface of the vertical rod through the side sleeve shell, and the bottom end of the lower pressure plate 15 extends to the inside of the outer guide shell 21 through the through hole, and the middle partition 161 can perform vertical sliding movement synchronously with the upper lower pressure plate 15, thereby driving the internal pressure of the hollow shell plates 162 on the upper and lower sides to change.

[0039] The modified slide plate 4 includes an oblique sliding shell 41, the top of the inner cavity of the oblique sliding shell 41 is evenly provided with through nozzles 42, the inner cavity of the oblique sliding shell 41 is evenly provided with auxiliary rollers 46, the front and rear sides of the axis of the auxiliary rollers 46 are fixedly connected with built-in motors 45, the outer surface of the built-in motor 45 is fixedly connected with a compression push rod 44 through a bent connecting rod, the bottom end of the compression push rod 44 is fixedly connected with a pressurizer 43, and the pressurizer 43 pressurizes and sprays the inside of the oblique sliding shell 41 and the compression push rod 44 by absorbing external air. The bottom of the outer surface of the oblique sliding shell 41 is fixedly connected to the outer surface of the vertical guide rail 23, the number of pressurizers 43 is five, the outer surface of the pressurizer 43 is fixedly connected to the bottom of the outer surface of the oblique sliding shell 41, and the outer surface of the auxiliary roller 46 extends to the outside of the oblique sliding shell 41 through a through groove.

[0040] In the process of the traction sleeve 14 pushing the lower pressure plate 15 to slide up and down, the vertical rod of the traction sleeve 14 will drive the middle partition 161 to slide up and down. When the middle partition 161 slides up, it will drive the upper hollow shell plate 162 to compress the segmented slide plate 163, thereby compressing the area between the segmented slide plate 163 and the hollow shell plate 162, thereby jetting upward through the notch of the notch conveyor belt 13. Since the stacked foam pad is located in the area where the sliding bellows 16 is located at this time, the stacked foam pad will be affected by the wind force from bottom to top; similarly, when the middle partition 161 slides down, the upper hollow shell plate 162 will draw air through the notch of the notch conveyor belt 13, and the drainage gas will pass through the outer surface of the stacked foam pad, so the stacked foam pad is in a cooling state when passing through the area where the sliding bellows 16 is located.

[0041] When the stacked foam pads slide down along the upper surface of the oblique sliding shell 41, the pressurizer 43 located on the lower surface of the oblique sliding shell 41 will push the compression push rod 44 by inflation, and the auxiliary roller 46 will pass through the through groove of the oblique sliding shell 41. At this time, the auxiliary roller 46 will press the lower surface of the stacked foam pads upward, and then contract the compression push rod 44 to make the stacked foam pads shake, thereby ensuring that the three foam pads in the stacked state can slide downward in a form of tightly fitting the retaining shell 51, reducing the misalignment phenomenon.

[0042] The built-in motor 45 controls the auxiliary roller 46 to rotate counterclockwise. When the auxiliary roller 46 contacts the lower surface of the foam pad, it drives the stacked foam pad to slide down to prevent the stacked foam pad from being stuck on the upper surface of the oblique sliding shell 41. At the same time, the jet is sprayed upward through the nozzle 42 to offset the pressure of the foam pad against the oblique sliding shell 41, thereby reducing the friction between the oblique sliding shell 41 and the foam pad, reducing the friction generated when the foam pad slides, and alleviating the wear of the foam pad.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
