Although the above-mentioned folding machine can realize automatic folding of non-woven bags, it is not suitable for folding and packing non-woven bags of different sizes, and has great limitations.

[0004] Therefore, the prior art has a large room for improvement. Summary of the invention

[0005] The purpose of the invention is to make up for the deficiencies of the prior art and to provide a non-woven bag folding machine.

[0006] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0007] A non-woven bag folding machine described in the present invention includes a folding mechanism, which includes a bottom plate, and a left folding plate and a right folding plate are symmetrically provided on the left and right sides of the bottom plate, and the left folding plate and the right folding plate are respectively driven by a first telescopic mechanism to move left and right, and a lower folding plate and an upper folding plate are sequentially provided above the bottom plate, and the upper folding plate and the lower folding plate are driven by a first lifting mechanism to move up and down in opposite directions or in opposite directions.

[0008] The opening of the non-woven bag is oriented toward the folding mechanism, so that the upper folding plate and the lower folding plate are placed inside the non-woven bag, and the right folding plate and the left folding plate are driven by the two first telescopic mechanisms to move the two plates to the left and right, and the lower folding plate and the upper folding plate are driven by the first lifting mechanism to move up and down to complete the folding process on the left and right sides of the non-woven bag. Through the above arrangement, the distance between the upper folding plate and the lower folding plate can be adjusted according to the thickness of the non-woven bag, and the upper folding plate and the lower folding plate of different sizes can be used according to the width of the non-woven bag, so that the non-woven bag is stretched and fixed on the upper folding plate and the lower folding plate before the folding operation, so as to prevent the deformation of the non-woven bag during the folding process from affecting the folding effect, and make the non-woven bag folding machine suitable for the folding process of non-woven bags of different sizes, which is conducive to improving practicality.

[0009] Those skilled in the art may set the widths of the upper folding plate and the lower folding plate to be the same as the width of the non-woven bag to open and fix the non-woven bag, or may use multiple folding plates arranged side by side.

[0010] According to the above scheme, a lower slide plate and an upper slide plate are sequentially arranged above the bottom plate, two lower folding plates that can slide left and right are arranged on the lower slide plate, and two upper folding plates that can slide left and right are arranged on the upper slide plate, and the upper slide plate and the lower slide plate are driven by the first lifting mechanism to move up and down in opposite directions or in opposite directions. The two upper folding plates and the lower folding plates can move left and right on the corresponding upper slide plate and the lower slide plate, so that they can be flexibly adjusted according to the width of different non-woven fabric bags, and the operation is simple and fast.

[0011] According to the above scheme, the first lifting mechanism includes a support frame and two hinged rods. The support frame is vertically fixed to the front side of the bottom plate. A connecting shaft is movably connected between the two hinged rods, and the connecting shaft is fixed to the support frame. The upper end of the hinged rod is connected to the upper movable plate in a transverse sliding manner, and the lower end is connected to the lower movable plate in a transverse sliding manner. The upper movable plate is fixedly connected to the upper slide plate, and the lower movable plate is fixedly connected to the lower slide plate. The upper slide plate is driven to move up and down by a driving component. When the driving component drives the upper slide plate to move upward, under the action of the two hinged rods, the lower slide plate moves downward, so that the upper slide plate and the lower slide plate move in opposite directions to increase the distance between the two slide plates. When the driving component drives the upper slide plate to move downward, under the action of the two hinged rods, the lower slide plate moves upward, so that the upper slide plate and the lower slide plate move toward each other to reduce the distance between the two slide plates. That is, by driving the upper slide plate to move upward or downward, the upper slide plate and the lower slide plate can be opened or closed at the same time.

[0012] According to the above scheme, a loading position is provided outside the folding mechanism, and a loading manipulator is provided on the loading position for pushing the non-woven bag into the folding mechanism. The non-woven bag can be automatically put on the folding mechanism by the loading manipulator.

[0013] According to the above scheme, a rear folding plate is provided above the loading position, and the rear folding plate is driven to move forward and backward by the second telescopic mechanism, and is driven to move up and down by the second lifting mechanism. The rear folding plate can be driven by the second telescopic mechanism to realize the inward folding of the bottom of the non-woven bag; when the folding process is completed, the second lifting mechanism drives the rear folding plate to move upward, providing an operating space for the non-woven bag to be fed from the front of the folding mechanism.

[0014] According to the above scheme, a conveying mechanism is included, and the output end of the conveying mechanism is arranged adjacent to the loading position. The conveying mechanism is matched with the loading manipulator, which is beneficial to improving the folding efficiency of the non-woven bag.

[0015] According to the above solution, the first telescopic mechanism, the second telescopic mechanism, the first lifting mechanism, and the second mechanism all include a driving component, which can be a motor, a cylinder, an oil cylinder, etc. according to the situation.

[0016] According to the above scheme, a turntable is included, and a plurality of folding mechanisms are evenly fixed on the turntable. When a folding mechanism completes the folding operation, the turntable is driven to rotate so that the folding mechanism at the next position rotates to the front of the loading position for folding operation, so that the non-woven bag folding machine can be used for batch folding of non-woven bags.

[0017] According to the above scheme, a material unloading position is provided on the outer side of the turntable, and a material unloading manipulator is provided on the material unloading position for pulling the non-woven bag out to the folding and shaping mechanism. The material unloading manipulator automatically pulls the folded non-woven bag out to the folding and shaping mechanism for the next shaping operation.

[0018] According to the above scheme, the folding and shaping mechanism includes a conveying roller, an upper conveyor belt assembly, and a lower conveyor belt assembly. The conveying roller is located in front of the lower conveyor belt assembly, and the upper conveyor belt assembly is located above the lower conveyor belt assembly. A conveying channel is provided between the upper conveyor belt assembly and the lower conveyor belt assembly, and the upper conveyor belt assembly and the upper surface of the conveying roller are located on the same horizontal line.

[0019] Under the action of the unloading robot and the conveying roller, the folded non-woven bag is conveyed to the conveying channel, and the upper conveyor belt assembly and the lower conveyor belt assembly are respectively attached to the non-woven bag up and down, and the non-woven bag is pressed while being conveyed, thereby improving the shaping effect.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-6 As shown, a non-woven bag folding machine described in the present invention includes a folding mechanism 1, and the folding mechanism 1 includes a bottom plate 11, and a left folding plate 12 and a right folding plate 13 are symmetrically provided on the left and right sides of the bottom plate 11, and the left folding plate 12 and the right folding plate 13 are respectively driven by a first telescopic mechanism 121 to move left and right, and a lower folding plate 15 and an upper folding plate 14 are sequentially provided above the bottom plate 11, and the upper folding plate 14 and the lower folding plate 15 are driven by a first lifting mechanism 18 to move up and down in opposite directions.

[0031] The opening of the non-woven bag is oriented toward the folding mechanism 1, so that the upper folding plate 14 and the lower folding plate 15 are placed inside the non-woven bag. The right folding plate 13 and the left folding plate 12 are driven by the two first telescopic mechanisms 121 to move the two to the left and right. At the same time, the lower folding plate 15 and the upper folding plate 14 are driven by the first lifting mechanism 18 to move up and down to complete the folding process on the left and right sides of the non-woven bag. The distance between the upper folding plate 14 and the lower folding plate 15 is adjusted according to the thickness of the non-woven bag, so that the non-woven bag is stretched and fixed on the upper folding plate 14 and the lower folding plate 15 before the folding operation, so as to prevent the deformation of the non-woven bag during the folding process from affecting the folding effect; the non-woven bag folding machine can be used for the folding process of non-woven bags of different sizes, which is conducive to improving practicality.

[0032] like Figure 2 As shown, a lower slide plate 17 and an upper slide plate 16 are sequentially arranged above the bottom plate 11, and the lower slide plate 17 is provided with two lower folding plates 15 that can slide left and right, and the upper slide plate 16 is provided with two upper folding plates 14 that can slide left and right, and the upper slide plate 16 and the lower slide plate 17 are driven by a first lifting mechanism 18 to move up and down in opposite directions or in opposite directions. The two upper folding plates 14 and the lower folding plates 15 can move left and right on the corresponding upper slide plates 16 and the lower slide plates 17, so that they can be flexibly adjusted according to the width of different non-woven fabric bags, and the operation is simple and fast.

[0033] like Figure 3As shown, the first lifting mechanism 18 includes a support frame 181 and two hinged rods 182. The support frame 181 is vertically fixed on the front side of the base plate 11. A connecting shaft 183 is movably connected between the two hinged rods 182, and the connecting shaft 183 is fixed on the support frame 181. The upper end of the hinged rod 182 is connected to the upper movable plate 161 for transverse sliding, and the lower end is connected to the lower movable plate 171 for transverse sliding. The upper movable plate 161 is fixedly connected to the upper slide plate 16, and the lower movable plate 171 is fixedly connected to the lower slide plate 17. The upper slide plate 16 is driven by a driving component to move up and down. When the driving component drives the upper slide 16 to move upward, under the action of the two hinged rods 182, the lower slide 17 moves downward, so that the upper slide 16 and the lower slide 17 move in opposite directions to increase the distance between them; when the driving component drives the upper slide 16 to move downward, under the action of the two hinged rods 182, the lower slide 17 moves upward, so that the upper slide 16 and the lower slide 17 move toward each other to reduce the distance between them. That is, by driving the upper slide 16 to move upward or downward, the upper slide 16 and the lower slide 17 can be opened or closed at the same time.

[0034] Specifically, the folding mechanism 1 includes a loading position 2 at the rear side thereof, and the loading position 2 is provided with a loading manipulator 21 for putting the non-woven bag on the upper folding plate 14 and the lower folding plate 15 of the folding mechanism 1.

The rear folding plate 3 is driven by the second telescopic mechanism 31 to realize the inward folding of the bottom of the non-woven bag; when the folding process is completed, the second lifting mechanism 32 drives the rear folding plate 3 to move upward, providing an operating space for the non-woven bag to be fed from the rear of the folding mechanism 1.

[0036] Furthermore, the first telescopic mechanism 121, the second telescopic mechanism 31, the first lifting mechanism 18, and the second lifting mechanism 32 all include a driving component, which can be a motor, a cylinder, an oil cylinder, etc. according to the situation.

[0037] Furthermore, it comprises a conveying mechanism 4, and the output end of the conveying mechanism 4 is arranged adjacent to the loading position 2. The conveying mechanism 4 is matched with the loading manipulator 21, which is beneficial to improving the folding efficiency of the non-woven bag.

[0038] like Figure 5As shown, it includes a turntable 5, on which a plurality of folding mechanisms 1 are evenly fixed. When one folding mechanism 1 completes the folding operation, the turntable 5 is driven to rotate so that the folding mechanism 1 at the next position rotates to the front of the loading position 2 for folding operation, so that the non-woven bag folding machine can be applied to batch folding processing of non-woven bags.

[0039] Furthermore, a material unloading position 6 is provided on the outer side of the turntable 5, and a material unloading manipulator 61 is provided on the material unloading position 6 for pulling the non-woven bag out to the folding and shaping mechanism 7. The material unloading manipulator 61 automatically pulls the folded non-woven bag out to the folding and shaping mechanism 7, so as to carry out the next shaping operation.

[0040] like Figure 6 As shown, the folding and shaping mechanism 7 includes a conveying roller 71, an upper conveying belt assembly 72, and a lower conveying belt assembly 73.

A conveying channel is provided between the upper conveying belt assembly 72 and the lower conveying belt assembly 73, and the upper surface of the upper conveying belt assembly 72 and the conveying roller 71 are located on the same horizontal line.

[0041] Under the action of the unloading robot 61 and the conveying roller 71, the folded non-woven bag is conveyed to the conveying channel, and the upper conveyor belt assembly 72 and the lower conveyor belt assembly 73 are respectively attached to the non-woven bag from top to bottom, and the non-woven bag is pressed while being conveyed, thereby improving the shaping effect.

[0042] When the non-woven bag folding machine of the present invention is used, the distance between the lower slide plate 17 and the upper slide plate 16, the distance between the two upper folding plates 14 on the upper slide plate 16, and the distance between the two lower folding plates 15 on the lower slide plate 17 are adjusted according to the size of the non-woven bags to be folded in batches; then the processed non-woven bags are placed on the conveying mechanism 4 in succession with the bag opening facing the folding mechanism 1, the conveying mechanism 4 conveys the non-woven bags to the loading position 2, and the loading robot 21 pushes the non-woven bags on the loading position 2 to the folding mechanism 1 in front of it, so that the non-woven bags are put on the upper folding plate 14, on the lower folding plate 15, so as to open and fix the non-woven bag; drive the rear folding plate 3 downward to the position where the rear folding plate 3 corresponds to the center position of the bottom side of the non-woven bag through the second lifting mechanism 32, and then drive the right folding plate 13 and the left folding plate 12 respectively through the two first telescopic mechanisms 121 to make the two move left and right relative to each other, and at the same time drive the lower folding plate 15 and the upper folding plate 14 to move up and down relative to each other through the first lifting mechanism 18, and drive the rear folding plate 3 forward through the second telescopic mechanism 31, so as to complete the inward folding process of the left and right sides and the bottom side of a non-woven bag. Drive the turntable to rotate so that the folding mechanism at the next position rotates to the front of the loading position 2, and the first telescopic mechanism 121, the second telescopic mechanism 31, the first lifting mechanism 18, and the second lifting mechanism 32 are reset, and the aforementioned folding process is repeated again.
