Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically a compression and packaging device for fluffy products. Background Technology

[0002] For fluffy products such as quilts, blankets, and mattresses, they usually need to be packaged in bags for storage and transportation. However, these fluffy products are too fluffy in their natural state, not only are they bulky, but they also tend to spring back after being squeezed, making them difficult to pack into bags smoothly and hindering packing efficiency.

[0003] On the other hand, in order to reduce packaging costs, these fluffy products are often stacked in multiple layers before being packaged together. This makes it even more difficult to fit them into the packaging bag smoothly, and also makes it difficult for the stacked fluffy products to remain neat in the packaging bag, resulting in poor packaging quality.

[0004] The aforementioned fluffy products are difficult to pack into packaging bags, resulting in low packaging efficiency and poor packaging quality. This problem exists not only in non-vacuum compression packaging methods but also in vacuum compression packaging methods.

[0005] Therefore, there is an urgent need for a solution that can improve the efficiency and quality of bagging and packaging fluffy products. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of the prior art and provide a compression and packaging device for fluffy products, so as to conveniently pack fluffy quilts, blankets, mattresses and other products into packaging bags.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A fluffy product compression and packaging device includes a frame with a vertical working end at the front end. The working end is equipped with an upper module and a lower module that cooperate with each other, and an ejector module located on the horizontal center line of the upper and lower modules facing each other. The frame is equipped with a first actuator for driving the upper and lower modules to open and close relative to each other, and a second actuator for driving the ejector module to extend and retract horizontally. The frame is also equipped with an electrical control unit for controlling the first and second actuators. The upper module has an upper guide plate that extends horizontally forward, and the lower module has a lower guide plate that extends horizontally forward.

[0009] As an improvement, the working end of the frame is provided with a pair of vertical guide rods that are separated to the left and right. The upper module has a first bushing that is sleeved on the vertical guide rod to form a sliding fit, and the lower module has a second bushing that is sleeved on the vertical guide rod to form a sliding fit.

[0010] Furthermore, at least one axially horizontal steering wheel is provided at the top of the frame. Flexible traction components corresponding to the steering wheels are connected between the upper module and the lower module. The two ends of the flexible traction components are fixed to the rear end of the upper module and the rear end of the lower module, respectively. The middle section of the flexible traction component passes around the corresponding steering wheel to form a transmission engagement. The steering wheel causes the flexible traction component to be tensioned. The first actuator is only used to drive one of the upper module and the lower module to move up and down along the vertical guide rod. And through the traction of the flexible traction component, the upper module and the lower module move in opposite directions along the vertical guide rod synchronously, thereby realizing relative opening and closing.

[0011] Preferably, the flexible traction element is a chain, and the steering wheel is a sprocket that meshes with the chain.

[0012] Optionally, the flexible traction element is a belt, and the steering wheel is a pulley that meshes with the belt.

[0013] As another improvement, the rear end of the ejector module is provided with a pair of horizontal guide rods arranged in left and right rows, and the working end of the frame is provided with a third bushing through which the horizontal guide rods pass to form a sliding fit.

[0014] As another improvement, both the first and second actuators use stroke cylinders.

[0015] As another improvement, the left and right sides of the lower guide plate each have an upward-folding first fold edge.

[0016] Furthermore, the upper guide plate has a second folded edge that slopes downward and expands outward on both the left and right sides.

[0017] As another improvement, it also includes a pair of mirror-symmetrical guardrail assemblies arranged on the left and right sides of the working end. The guardrail assembly includes an upper guardrail, a middle guardrail, and a lower guardrail connected in sequence. The upper end of the upper guardrail is pivotally connected to the side edge of the upper guide plate, and the lower end of the upper guardrail is pivotally connected to the upper end of the middle guardrail. The middle guardrail is set vertically. The upper end of the lower guardrail is pivotally connected to the lower end of the middle guardrail, and the lower end of the lower guardrail is pivotally connected to the side edge of the lower guide plate. A light axis guide rod is fixedly installed on the rear side of the middle guardrail and extends horizontally into the frame. The frame is provided with a fourth bushing through which the light axis guide rod passes and slides. The rear end of the light axis guide rod passes through the fourth bushing and is fitted with a cylindrical spring. A baffle for blocking the cylindrical spring is also fixedly connected to the rear end of the light axis guide rod.

[0018] Compared with the prior art, this utility model has the following advantages: Multiple fluffy products, either individually or in layers, are placed on the lower guide plate of the lower module. The first actuator drives the upper and lower modules to move closer together, compressing the fluffy products through the clamping action of the upper and lower guide plates. This allows the packaging bag to be conveniently fitted onto the clamping structure formed by the upper and lower guide plates. The ejector module then pushes the fluffy products clamped between the upper and lower guide plates forward, allowing them to smoothly and neatly enter the packaging bag, and consequently, the packaging bag to detach from the upper and lower guide plates. The machine is small in size, has a large stroke, high packaging efficiency, and good packaging quality.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0027] Please see Figure 1 and Figure 2As shown, this utility model provides a compression and packaging device for fluffy products. Its structure includes a frame 1, with a vertical working end 10 at the front end of the frame 1. The working end 10 is provided with an upper module 2 and a lower module 3 that cooperate with each other, and an ejector module 4 located on the horizontal center line of the upper module 2 and the lower module 3 facing each other. The frame 1 is provided with a first actuator 5 for driving the upper module 2 and the lower module 3 to open and close relative to each other, and a second actuator 6 for driving the ejector module 4 to extend and retract horizontally. The frame 1 is also provided with an electrical control unit 7 for controlling the first actuator 5 and the second actuator 6. The upper module 2 has an upper guide plate 21 that extends horizontally forward, and the lower module 3 has a lower guide plate 31 that extends horizontally forward.

[0028] The compressed packaging device for fluffy products of this invention significantly improves packaging efficiency and quality for fluffy products such as quilts, blankets, and mattresses.

[0029] Specifically, in combination Figures 3 to 5 The working principle of this utility model is described as follows.

[0030] like Figure 3 As shown, when a single or stacked multiple fluffy products 100 are placed on the lower guide plate 31 of the lower module 3, and the first actuator 5 drives the upper module 2 and the lower module 3 to move closer to each other, the fluffy products 100 can be compressed by the clamping cooperation of the upper guide plate 21 and the lower guide plate 31.

[0031] Furthermore, such as Figure 4 As shown, the packaging bag 200 can be conveniently attached to the clamping structure composed of the upper guide plate 21 and the lower guide plate 31 by manual operation or with supporting auxiliary equipment.

[0032] Furthermore, such as Figure 5 As shown, the fluffy product 100 held between the upper guide plate 21 and the lower guide plate 31 is pushed forward by the ejection module 4, so that the fluffy product 100 smoothly and neatly enters the packaging bag 200, and the packaging bag is detached from the upper guide plate 21 and the lower guide plate 31, thus completing the packaging of the fluffy product.

[0033] Finally, the upper module 2, lower module 3, and ejector module 4 are reset and ready for the next round of packaging operations.

[0034] The main function of this invention's fluffy product compression and packaging device is to facilitate the easier packing of fluffy products into packaging bags. Clearly, the choice of packaging bag type is not significantly limited; any bag that can open and fit onto the clamping structure formed by the upper guide plate 21 and the lower guide plate 31 can be used as a packaging bag. Therefore, this invention's fluffy product compression and packaging device can use both non-vacuum compression packaging bags and vacuum compression packaging bags. For non-vacuum compression packaging bags, after packing the fluffy product, the product is slightly compressed due to the bag's constraint, and the bag can be sealed directly. For vacuum compression packaging bags, after packing the fluffy product, air is removed from the bag using a known vacuuming method, allowing for further deep compression of the fluffy product using negative pressure.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the working end 10 of the frame 1 is provided with a pair of vertical guide rods 11, which are separated to the left and right. The upper module 2 has a first bushing 22 that is fitted onto the vertical guide rods 11 to form a sliding fit, and the lower module 3 has a second bushing 32 that is fitted onto the vertical guide rods 11 to form a sliding fit. With the aforementioned arrangement, the upper module 2 and the lower module 3 will move vertically up and down along the vertical guide rods 11, making the operation smoother and the clamping and positioning more accurate.

[0036] Furthermore, at least one axially horizontal steering wheel 12 is provided at the top of the frame 1. Flexible traction members 13, corresponding one-to-one with the steering wheels 12, are connected between the upper module 2 and the lower module 3. The two ends of the flexible traction member 13 are fixed to the rear ends of the upper module 2 and the lower module 3, respectively. The middle section of the flexible traction member 13 passes around the corresponding steering wheel 12 to form a transmission engagement. The steering wheel 12 tensions the flexible traction member 13. The first actuator 5 is only used to drive one of the upper module 2 and the lower module 3 to move up and down along the vertical guide rod 11. Through the traction of the flexible traction member 13, the upper module 2 and the lower module 3 move synchronously in opposite directions along the vertical guide rod 11, thereby achieving relative opening and closing. With the aforementioned arrangement, under the action of the flexible traction member 13, the upper module 2 and the lower module 3 obtain synchronous reverse strokes, so that the clamping stroke range formed by the upper guide plate 21 and the lower guide plate 31 will be equal to twice the stroke of the upper module 2 or the lower module 3. In other words, the drive stroke of the first actuator 5 only needs to be set to half of the desired clamping stroke range formed by the upper guide plate 21 and the lower guide plate 31, which to a certain extent achieves miniaturization of the whole machine, reduces the manufacturing cost of the frame 1, and reduces the space occupied by the whole machine. Taking the first actuator 5 as an example using a stroke cylinder, a stroke cylinder with a stroke of 550 cm can achieve a compression stroke of 1100 cm through the upper and lower guide plates, which can compress a fluffy product with a height of 1500 cm to 400 cm. Obviously, this compression ratio greatly reduces the difficulty and labor intensity of bagging.

[0037] like Figure 2 As shown, in a preferred embodiment, the first actuator 5 has two juxtaposed parts to increase the force.

[0038] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the flexible traction member 13 has two arranged in a left-right row, which are used to connect the two ends of the upper module and the two ends of the lower module respectively. Correspondingly, the steering wheel 12 also has two arranged in a left-right row, which are used to cooperate with the flexible traction member 13 respectively.

[0039] Preferably, the flexible traction element 13 is a chain, and the steering wheel 12 is a sprocket that meshes with the chain.

[0040] Optionally, the flexible traction element 13 is a belt, and the steering wheel 12 is a pulley that meshes with the belt.

[0041] As another improvement, the rear end of the ejector module 4 is provided with a pair of horizontally arranged guide rods 41, and the working end 10 of the frame 1 is provided with a third bushing 14 for the horizontal guide rods 41 to pass through and form a sliding fit. With the aforementioned arrangement, the ejector module 4 operates more smoothly and stably when it extends and retracts, thanks to the cooperation of the horizontal guide rods 41 and the third bushing 14.

[0042] As another improvement, both the first actuator 5 and the second actuator 6 use stroke cylinders.

[0043] As another improvement, the left and right sides of the lower guide plate 31 each have an upward-folded first folded edge 30, which is used to block the bottom sides of the fluffy product and prevent it from deviating from the lower guide plate 31 when compressed.

[0044] Furthermore, the upper guide plate 21 has downward-sloping and outward-expanding second folds 20 on its left and right sides, which are used to constrain the top sides of the fluffy product, so that it can be kept as centered as possible when compressed, and better kept neat inside the packaging bag.

[0045] As another improvement, the bottom of the frame 1 is provided with support feet 19 extending forward in the horizontal direction on the left and right sides, which are used to optimize the center of gravity of the whole machine. This can prevent the frame 1 from tilting forward after the product load is placed on the lower guide plate 31, thus improving the stability of the frame 1.

[0046] To more effectively prevent the fluffy products on the lower guide plate 31 from tilting or even slipping during clamping and compression, the fluffy product compression and packaging device of this utility model also includes a pair of mirror-symmetrical guardrail components arranged on the left and right sides of the working end, as detailed below. Figure 6 and Figure 7 As shown: The guardrail assembly includes an upper section railing 81, a middle section railing 82, and a lower section railing 83 connected in sequence. The upper end of the upper section railing 81 is pivotally connected to the side edge of the upper guide plate 21, and the lower end of the upper section railing 81 is pivotally connected to the upper end of the middle section railing 82. The middle section railing 82 is vertically arranged. The upper end of the lower section railing 83 is pivotally connected to the lower end of the middle section railing 82, and the lower end of the lower section railing 83 is pivotally connected to the side edge of the lower guide plate 31. A light axis guide rod 84 is fixedly installed on the rear side of the middle section railing 82, which extends horizontally into the frame 1. The frame 1 is provided with a fourth bushing 15 through which the light axis guide rod 84 passes and slides. The rear end of the light axis guide rod 84 passes through the fourth bushing 15 and is fitted with a cylindrical spring 85. A baffle 86 for blocking the cylindrical spring 85 is also fixedly connected to the rear end of the light axis guide rod 84.

[0047] Figure 6 The diagram shows the state of the guardrail assembly after the upper guide plate 21 and lower guide plate 31 have opened and reset. Specifically, when the upper guide plate 21 and lower guide plate 31 open and reset, the upper section 81 and lower section 83 will pivot vertically relative to the middle section 82, causing the optical axis guide rod 84 to be pulled forward along the fourth bushing 15. When the optical axis guide rod 84 extends forward to the end of its stroke, the cylindrical spring 85 is compressed under the action of the baffle 86 and abuts against the rear end of the fourth bushing 15.

[0048] Figure 7The diagram illustrates the state of the guardrail assembly after the upper guide plate 21 and lower guide plate 31 approach each other to form a clamping engagement. Specifically, when the upper guide plate 21 and lower guide plate 31 approach each other to form a clamping engagement, the optical axis guide rod 84 is no longer pulled forward, the compressed cylindrical spring 85 is released, and the optical axis guide rod 84 is pulled backward along the fourth bushing 15, causing the upper section railing 81 and the lower section railing 83 to pivot forward relative to the middle section railing 82, respectively. Furthermore, the forward pivoting of the upper section railing 81 and the lower section railing 83 relative to the middle section railing 82 will continue as the upper guide plate 21 and lower guide plate 31 continue to approach each other, causing the optical axis guide rod 84 to be continuously pulled backward along the fourth bushing 15 until the upper guide plate 21 and lower guide plate 31 complete the clamping engagement.

[0049] from Figure 6 and Figure 7 As can be seen from the working principle shown, the left and right guardrail components always block the space between the guide plate 21 and the lower guide plate 31 in the left and right directions, which can obviously effectively prevent the fluffy products on the lower guide plate 31 from tilting or even slipping when they are clamped and compressed.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
