Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machines, and specifically provides an adsorption-type cloth clamping module and a bag opening machine. Background Art

[0002] The bag opening machine is used to cut and open the bag opening on the fabric, and then form the bag opening by folding and sewing. After the bag opening is formed, it can be sewn with a layer of bag cloth. After a layer of bag cloth is sewn on one side of the bag opening, it can be further sewn with the fabric to form a pocket; or, after a layer of bag cloth is sewn on one side of the bag opening, it can be sewn with the fabric forming the bag opening to form a pocket; or, another layer of bag cloth can be sewn on the other side of the bag opening, and finally the bag cloth on both sides of the bag opening can be sewn, so that the two layers of bag cloth and the bag opening are combined to form a pocket.

[0003] However, the bag cloth is a piece of cloth and needs to be kept flat during sewing, so the bag cloth needs to be laid flat on the frame platform of the bag opening machine. After sewing one layer of bag cloth, when putting in the second layer of bag cloth, the second layer of bag cloth needs to be overlapped with the first layer of bag cloth. During the overlapping process, the second layer of bag cloth will be blocked by the first layer of bag cloth. For example, if the second layer of bag cloth is moved to the lower side of the first layer of bag cloth through other trays, there will be a gap between the first layer of bag cloth and the frame platform, and under the action of gravity, the first layer of bag cloth will deform downward. When the second layer of bag cloth approaches the first layer of bag cloth, it will contact the first layer of bag cloth. When the second layer of bag cloth continues to move, it will be subject to friction resistance from the first layer of bag cloth, causing the second layer of bag cloth to shift in position or wrinkle, resulting in an incorrect sewing position. If the bag mouth and the first layer of bag cloth are moved to the upper side of the second layer of bag cloth, there will be a problem of the first layer of bag cloth interfering with the position of the second layer of bag cloth during the process of moving the first layer of bag cloth to the second layer of bag cloth. Therefore, when the existing bag opening machine overlaps two layers of bag cloth, the two layers of bag cloth interfere with each other, causing the second layer of bag cloth to shift position or wrinkle. Utility Model Content

[0004] The utility model provides an adsorption type cloth clamping module and a bag opening machine, which are used to solve the problem that when two layers of bag cloth are overlapped, the two layers of bag cloth interfere with each other and cause the position of the second layer of bag cloth to shift or wrinkle.

[0005] The technical solution of the utility model is as follows:

[0006] An adsorption-type cloth clamping module comprises a base plate and a pressure frame, wherein the base plate is provided with a lifting mechanism, the pressure frame is connected to the lifting mechanism, the base plate is provided with a through hole, the position of the through hole corresponds to the pressure frame, the through hole runs through the upper and lower sides of the base plate, and an adsorption structure is provided at the bottom of the base plate.

[0007] In this solution, the pressing frame and the bottom plate can be used to press and fix the bag opening, and the through hole provided on the bottom plate allows the sewing needle to pass through, so as to sew the bag opening on the upper side of the bottom plate and the bag cloth on the lower side of the bottom plate. The adsorption structure provided at the bottom of the bottom plate can be used to adsorb the bag cloth located on the lower side of the bottom plate. Therefore, after the first layer of bag cloth is sewn to the bag opening, the first layer of bag cloth is adsorbed to the bottom surface of the bottom plate by the adsorption structure. At this time, the first layer of bag cloth fits the bottom surface of the bottom plate. When the second layer of bag cloth is moved to the lower side of the bottom plate, the first layer of bag cloth will not sag under the action of gravity, and will not contact the second layer of bag cloth in advance, and will not cause the position of the second layer of bag cloth to be offset or cause wrinkles to the second layer of bag cloth.

[0008] The adsorption structure is arranged on one side of the through hole.

[0009] In this solution, the connection position between the bag opening and the bag cloth is relatively fixed, so it is only necessary to provide an adsorption structure on one side of the through hole to achieve the purpose of adsorbing the bag cloth.

[0010] The adsorption structure is an adsorption hole, the bottom plate is provided with a negative pressure pipeline connected with the adsorption hole, and the other end of the negative pressure pipeline is provided with a negative pressure mechanism.

[0011] In this solution, the adsorption structure adopts adsorption holes, which can be directly processed on the bottom surface of the bottom plate to reduce the processing cost. In addition, the adsorption holes will not affect the flatness of the bottom surface of the bottom plate.

[0012] The negative pressure pipeline is a channel constructed in the bottom plate, one end of the channel is connected to the adsorption hole, and the other end of the channel is connected to the negative pressure mechanism.

[0013] In this solution, a channel is directly constructed in the base plate to form a negative pressure pipe, and there is no need to install pipes and other structures separately in or on the base plate, which can reduce the difficulty of installing the negative pressure pipe.

[0014] The adsorption type cloth clamping module comprises at least two adsorption holes, and each adsorption hole is arranged in an array on the bottom surface of the bottom plate.

[0015] In the present embodiment, at least two adsorption holes are provided. Compared with only one adsorption hole, the adsorption area can be increased. Based on more adsorption points of the bag cloth, it is ensured that the bag cloth can be adsorbed on the bottom of the base plate as a whole, preventing the edge of the bag cloth and other positions from sagging under the action of gravity and affecting the position of the second layer of bag cloth.

[0016] The adsorption type cloth clamping module comprises at least two negative pressure pipes, each adsorption hole is communicated with each negative pressure pipe respectively, and each negative pressure pipe is provided with a valve respectively.

[0017] In this solution, at least two negative pressure pipes are provided to provide negative pressure for different adsorption holes respectively, thereby controlling the adsorption area of ​​the bottom surface of the bottom plate to be suitable for bag cloths of different sizes.

[0018] The valve is a stop valve.

[0019] In this solution, the shut-off valve can be used to directly control the connectivity of the negative pressure pipeline.

[0020] The bottom surface of the bottom plate is provided with a plane area, and the adsorption structure is arranged in the plane area.

[0021] In this solution, a flat area is provided on the bottom surface of the bottom plate, which can ensure that when the bottom plate moves downward to fit the bag cloth, the bag cloth can be flattened by the flat area, so that the bag cloth is completely fitted with the bottom surface of the bottom plate. The adsorption structure is provided on the flat area, which can ensure that all positions of the bag cloth can contact the adsorption structure at the bottom of the bottom plate.

[0022] The utility model also provides a bag opening machine, comprising the above-mentioned adsorption type cloth clamping module, and also comprising a support frame, wherein the adsorption type cloth clamping module is connected to the support frame.

[0023] In this solution, the bag opening machine uses an adsorption-type cloth clamping module, which can solve the problem that the first layer of bag cloth interferes with the position of the second layer of bag cloth when the bag opening machine sews two layers of bag cloth, thereby preventing the second layer of bag cloth from moving or wrinkling.

[0024] The bag opening machine also includes a three-axis module, and the adsorption-type cloth clamping module is connected to the support frame via the three-axis module.

[0025] In this solution, the base plate is driven to move in three-dimensional space by a three-axis module, that is, the suction-type fabric clamping module is driven to rise and fall, move forward and backward, and move left and right by a three-axis module. Usually, the support platform also needs to cooperate with the cutting tool and sewing tool to work, the basic position of the support platform needs to be stable and immovable, and the mass and area of ​​the support platform are larger than the suction-type fabric clamping module. Therefore, compared with driving the support platform to move, using a three-axis module to drive the suction-type fabric clamping module is easier to install, and the position of the support platform can be stable, which improves the cutting and sewing accuracy.

[0026] Beneficial effects of the utility model:

[0027] The utility model is provided with an adsorption structure at the bottom of the bottom plate. After the bag mouth is sewn to a layer of bag cloth, the bag cloth is attached to the bottom plate under the action of the adsorption structure, so that when the second layer of bag cloth moves to the lower side of the first layer of bag cloth, the first layer of bag cloth will not contact the second layer of bag cloth, and the position of the second layer of bag cloth will not be shifted or wrinkled.

[0038] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0039] Embodiment 1.

[0040] like Figure 1 and Figure 2As shown, the present embodiment 1 provides an adsorption-type cloth clamping module, including a base plate 1, a pressing frame 3 and a lifting mechanism, wherein the pressing frame 3 is connected to the base plate 1 through the lifting mechanism, and the lifting mechanism is used to drive the pressing frame 3 to lift and lower, so that the pressing frame 3 can clamp or release the bag opening. The base plate 1 is provided with a through hole 2, and the position of the through hole 2 corresponds to the pressing frame 3. In the prior art, the pressing frame 3 is an annular structure, and a hole is provided in the middle of the pressing frame 3, and the hole corresponds to the position of the through hole 2 on the base plate 1, which means that the hole is located on the upper side of the through hole 2, and the sewing needle can pass through the hole and the through hole 2 to sew the bag opening fixed by the pressing frame 3 with the bag cloth on the lower side of the base plate 1. An adsorption structure is provided at the bottom of the base plate 1, and the adsorption structure is used to adsorb and fix the bag cloth.

[0041] Under the action of the adsorption structure, the bag cloth and the bottom surface of the bottom plate 1 always remain in contact with each other. After one side of the bag cloth is sewn to the bag opening, another layer of bag cloth needs to be placed under the bag cloth. At this time, the lower side of the first layer of bag cloth that has been sewn will lose support, which is convenient for placing the second layer of bag cloth. The first layer of bag cloth will remain in contact with the bottom plate 1 under the action of the adsorption structure. When the second layer of bag is placed, the first layer of bag cloth will not contact the second layer of bag cloth, and will not affect the position of the second layer of bag cloth. After the second layer of bag cloth is placed, the first layer of bag cloth and the second layer of bag cloth are close to and overlapped, which is convenient for sewing the bag opening and the second layer of bag cloth. In the process of the first layer of bag cloth and the second layer of bag cloth approaching each other, the first layer of bag cloth will not sag and cause the second layer of bag cloth to move or wrinkle. Ensure that the first layer of bag cloth and the second layer of bag cloth are both in a flat state, so as to ensure the accurate sewing position of the second layer of bag cloth and the bag opening and ensure the accuracy of sewing.

[0042] The adsorption structure is an adsorption hole 6 opened on the bottom plate 1 , and the adsorption hole 6 is connected to a negative pressure device through a negative pressure pipeline, for example, connected to a vacuum pump through a negative pressure pipeline.

[0043] The bottom plate 1 is provided with at least two adsorption holes 6, and each adsorption hole 6 is arranged in an array. For example, each adsorption hole 6 is provided on the bottom plate 1 in a rectangular array, a circular array, etc. The more adsorption holes 6 are provided on the bottom plate 1, the more adsorption points the adsorption holes 6 have on the bag cloth, and the bag cloth is subjected to a more uniform force, thereby ensuring that each position of the bag cloth is adsorbed by the adsorption holes 6, so that the entire bag cloth is flatly attached to the bottom surface of the bottom plate 1.

[0044] like Figure 3 As shown, the negative pressure pipe can be a rubber tube or a plastic tube connected to the adsorption hole 6. The negative pressure channel 7 can also be a channel 7 constructed on the bottom plate 1, for example, a circular hole is constructed on the bottom plate 1, so that one end of the circular hole is connected to one or more adsorption holes 6, and the other end is connected to the negative pressure device through a connecting pipe. If the channel 7 is constructed on the bottom plate 1, the number of pipes connected to the entire adsorption-type cloth clamping module can be reduced, thereby achieving the purpose of streamlining the structure.

[0045] To ensure that the bag cloth is flatly adsorbed on the bottom plate 1, the bottom plate 1 is provided with a plane area, and the adsorption holes 6 are all provided in the plane area. The plane area is used to press the bag cloth from the upper side to ensure that all the adsorption holes 6 can adsorb the bag cloth. When the bag cloth is adsorbed on the bottom plate 1, since the bag cloth is located in the plane area, it can be ensured that the bag cloth remains flat.

[0046] like Figure 1 and Figure 4 As shown, the lifting mechanism can adopt a combination of an electric cylinder and a guide rail 5, or can adopt a combination of a cylinder 4 and a guide rail 5. For example, a guide rail 5 in the vertical direction is set on the base plate 1, and a cylinder 4 in the vertical direction is configured. One end of the cylinder 4 is connected to the base plate 1, and the other end of the cylinder 4 is connected to the press frame 3. A slider adapted to the guide rail 5 is set on the press frame 3, and the slider is slidably connected to the guide rail 5. When the cylinder 4 is extended, the press frame 3 moves upward, and the bag opening can be placed on the lower side of the press frame 3. After the bag opening is placed, the cylinder 4 is shortened, and the press frame 3 moves downward to press the bag opening. The cylinder 4 and the guide rail 5 are respectively arranged on both sides of the press frame 3 to ensure that the forces on both sides of the press frame 3 are the same, so that the press frame 3 can be lifted and lowered more smoothly.

[0047] Embodiment 2.

[0048] The second embodiment provides an adsorption-type cloth clamping module. The difference from the first embodiment is that the adsorption structure in the second embodiment is different.

[0049] like Figure 5 As shown, the adsorption structure uses a double-sided adhesive tape 8, which is attached to the bottom plate 1 and is located in the plane area at the bottom of the bottom plate 1. When the bottom plate 1 presses the bag cloth from the upper side, the double-sided adhesive tape 8 can adhere to the bag cloth and adhere the bag cloth to the bottom of the bottom plate 1. The double-sided adhesive tape 8 is arranged in a linear array at the bottom of the bottom plate 1, and is adhered and fixed to the edge and the middle of the bag cloth respectively.

[0050] Embodiment three.

[0051] The third embodiment provides an adsorption-type cloth clamping module. Different from the first embodiment, at least two negative pressure pipes are provided in the present embodiment, and each adsorption hole 6 is connected to each negative pressure pipe respectively, and each negative pressure pipe is provided with a valve respectively.

[0052] like Figure 6 As shown, the adsorption holes 6 on the bottom plate 1 can be divided into different areas, and the adsorption holes 6 in different areas are connected to different negative pressure pipes. The valve can be a stop valve, and opening the valve can connect and disconnect the corresponding negative pressure pipe. When the negative pressure pipe is in a disconnected state, the adsorption holes 6 corresponding to the negative pressure pipe cannot be used to bag cloth. In other words, by controlling the connection state of the negative pressure pipe, the adsorption area of ​​the adsorption holes 6 on the bottom plate 1 can be controlled to be suitable for bag cloths of different sizes.

[0053] by Figure 6 For example, Figure 6 There are 9 vertically arranged adsorption holes 6 in total, and the 5 centrally arranged adsorption holes 6 are interconnected through channels 7, and finally converged into one channel 7, which is connected to the negative pressure device. The 4 adsorption holes 6 located on both sides are connected to four channels 7 respectively, and the adsorption range of the adsorption holes 6 on the bag cloth can be controlled by controlling the connection states of the four channels 7 respectively, so as to be suitable for bag cloths of different lengths. Similarly, horizontally arranged through holes 6 can also be provided on the bottom plate 1 to be suitable for bag cloths of different widths.

[0054] Embodiment 4.

[0055] The fourth embodiment provides a bag opening machine, comprising the adsorption-type cloth clamping module described in any one of the first to third embodiments.

[0056] like Figure 7 As shown, the bag opening machine is provided with a support frame 9 and a frame platform, and the frame platform is a platform structure provided on the support frame 9. The frame platform can be used for placing bag cloth.

[0057] The support frame 9 is provided with a three-axis module, and the adsorption type cloth clamping module is connected to the support frame 9 via the three-axis module, and the adsorption type cloth clamping module can be moved via the three-axis module.

[0058] During operation, after the bag opening is fixed on the adsorption-type cloth clamping module, the bag cloth is placed on the rack platform, and the adsorption-type cloth clamping module is moved to the upper side of the bag cloth by the three-axis module, and then the height of the adsorption-type cloth clamping module is lowered so that the bottom plate 1 of the adsorption-type cloth clamping module is pressed on the upper side of the bag cloth, and the bag cloth and the bag opening are aligned at the position where they need to be sewn. Then the adsorption-type cloth clamping module moves along the surface of the rack platform, and under the action of friction, the adsorption-type cloth clamping module drives the bag cloth to move along the surface of the rack platform, and after moving to a position where it can be sewn, the bag opening and the bag cloth are sewn. At this time, the bag cloth is adsorbed and fixed to the bottom surface of the adsorption-type cloth clamping module by the adsorption structure, and then the second layer of bag cloth is placed on the rack platform, and the adsorption-type cloth clamping module can be moved to the upper side of the second layer of bag cloth by the three-axis module. Since the previously stitched first layer of bag cloth is tightly attached to the bottom plate 1 of the adsorption-type cloth clamping module under the action of the adsorption structure, the first layer of bag cloth will not sag and contact the second layer of bag cloth during the process of the adsorption-type cloth clamping module moving to the upper side of the second layer of bag cloth, and the position of the second layer of bag cloth will not be shifted. When the adsorption-type cloth clamping module moves downward, the first layer of bag cloth and the second layer of bag cloth remain flat without wrinkles, ensuring that the second layer of bag cloth is subjected to the same force at all locations. When the adsorption-type cloth clamping module moves along the rack platform, the second layer of bag cloth moves with the friction of the first layer of bag cloth. During the movement, there are no wrinkles between the first layer of bag cloth and the second layer of bag cloth, so the second layer of bag cloth is subjected to the same force at all locations, and will not be displaced, deformed, or wrinkled relative to the first layer of bag cloth during the movement, ensuring the stitching accuracy when the second layer of bag cloth moves to the stitching position.
