Description

Technical Field

[0001] The invention relates to the field of bag sticking machine components, in particular to a quick positioning negative pressure adsorption device. Background Art

[0002] At present, China Patent Network has published a pocket sewing machine with announcement number (CN104630991A), which includes a fuselage, a bag folding device, a sewing mold, a sewing machine and a driving device; the fuselage is a rectangular box, the upper surface of the fuselage is a working platform, a fan is arranged inside the fuselage, the air outlet of the fan is connected to the air inlet of the blowing and suction conversion device, the air outlet of the blowing and suction conversion device is connected to one end of the air duct, the other end of the air duct leads to the air cavity under the working platform, and a plurality of small air outlets are opened on the surface of the working platform; a bracket is fixed laterally to the fuselage, two tracks are arranged between the bracket and the fuselage, the track is arranged laterally parallel to the bracket, the bag folding device is fixed on the left side of the bracket, the sewing mold is fixed on a track on the bracket, and the sewing machine is installed on the right side of the working platform.

[0003] Although the above-mentioned pocket sewing machine can replace manual work, since the pocket fabric is positioned by mechanical pressing of a spring sheet, the spring sheet directly contacts the pocket fabric and has a large clamping force on the pocket fabric. Therefore, there is a problem 1: during the pocket processing, when workers place the pocket fabric, it is difficult to ensure accurate positioning. Another problem 2: when the material sheet tongue is extended and withdrawn, the spring sheet still presses the pocket fabric. The action of the material sheet tongue pressing can easily drive the pocket fabric, causing the pocket fabric to shift, thereby affecting the position of the pocket fabric, and further causing inaccurate positioning of the pocket fabric. It can be seen from the above that the reliability of the above-mentioned structure still has major defects. Summary of the invention

[0004] The present invention aims to solve the related technical problems at least to a certain extent. In view of this, the present invention aims to provide a quick positioning negative pressure adsorption device, which adopts the airflow guiding principle to position the adsorption cloth, thereby improving the reliability of cloth positioning and the convenience of operation.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a quick positioning negative pressure adsorption device, including a material tongue depressor, a pocket cloth positioning piece, a tongue depressor fixing frame, and a telescopic mechanism installed on the tongue depressor fixing frame and driving the pocket cloth positioning piece to move horizontally; the pocket cloth positioning piece is slidably matched with the material tongue depressor, and the pocket cloth positioning piece is provided with an airway, a limiting portion suspended and extended in the direction of the cloth, and a guide channel located below the limiting portion and cooperating with the material tongue depressor to form an aisle, and the air outlet of the airway is below the limiting portion and sprays air toward the guide channel.

[0006] Through the above arrangement, the material tongue is used to support the fabric. In the initial state, the pocket fabric positioning piece fits against the material tongue, and the air is ejected through the airway and cooperates with the guide channel to form a negative pressure below the limit part. The suspended and extended structure of the limit part plays a role, so that the pocket fabric can fit on the limit part and the pocket fabric is adsorbed by the negative pressure, which is convenient for workers to operate and position. More importantly: for the airflow-guided adsorption method, in operation, after the workers place the pocket fabric, the negative pressure generated is convenient for the staff to position the pocket fabric in the best position, the air adsorption force is relatively gentle, and the workers' operation is safe and reliable. After the pocket is folded, the airflow is turned off, and when the pocket fabric positioning piece is evacuated, the pocket fabric positioning piece has no force on the pocket fabric. This solution effectively solves the problem of pocket fabric placement and positioning, as well as the problem of pocket fabric displacement during the expansion and contraction and evacuation of the material tongue.

[0007] As a specific solution of the present invention, it may be preferred that: the airway, the limiting portion, and the guide channel are symmetrically arranged on both sides of the pocket cloth positioning piece.

[0008] Through the above arrangement, a symmetrical distribution structure is adopted, so that the adsorption force is uniform and the positioning is accurate.

[0009] As a specific solution of the present invention, it can be preferably that: the airway includes an air inlet located above the pocket cloth positioning piece, an air flow channel transversely penetrating and connecting to the air inlet, and an air outlet connected to the limiting portion, and one end of the air flow channel is blocked.

[0010] Through the above arrangement, this structure is designed with processing in mind, which is convenient for processing and has additional effects on the air flow channel: first, it is convenient for processing so that the air inlet and the air flow channel can be connected; second, it is easy to clean. When in use, the air flow channel is blocked, and it can be opened and unblocked during cleaning, and air can also be sprayed out.

[0011] As a specific solution of the present invention, it can be preferred that: a step block is provided at the bottom of the pocket cloth positioning piece, and the step block is engaged with the edge portion of the material sheet pressing tongue.

[0012] Through the above arrangement, the step block can effectively locate the sliding position of the cloth positioning block to avoid excessive sliding. On the other hand, it can form a guide channel with the material sheet pressure tongue.

[0013] As a specific solution of the present invention, it can be preferably that: a plurality of installation grooves arranged along the movement direction of the pocket cloth positioning piece are arranged on the tail portion, a roller piece is fixed on the installation groove, and a waist-shaped groove for guiding the roller piece to slide is arranged at the tail portion of the sheet pressing tongue.

[0014] Through the above arrangement, the plurality of mounting grooves are used to facilitate adjustment of the mounting position of the roller member, thereby adjusting the travel length of the roller member in the waist-shaped groove.

[0015] As a specific solution of the present invention, it can be preferred that: a slide groove is provided on the tongue depressor fixing frame, a slide rod installed in the slide groove is fixed on the pocket cloth positioning piece, and the end of the slide rod is fixedly connected to the telescopic mechanism.

[0016] Through the above arrangement, the sliding groove and the sliding rod cooperate with each other, so that the sliding action of the two is more stable and reliable.

[0017] As a specific solution of the present invention, it can be preferred that: the telescopic mechanism is a micro cylinder, the body of the micro cylinder is fixed on the tongue depressor fixing frame, and the telescopic rod of the micro cylinder is fixedly connected to the bottom surface of the sliding rod.

[0018] Through the above arrangement, the installation method of the micro cylinder is concealed and can make more effective space. In terms of assembly, the trachea is installed on the airway to provide positive pressure air. In order to ensure the sliding of the pocket fabric positioning piece relative to the tongue pressing piece of the material, the trachea will inevitably be constantly folded, reducing the service life of the trachea. The sliding rod of this structure is hollow, and the trachea is installed inside the sliding rod. Therefore, in this structure, a micro cylinder is used to drive the sliding rod to move, and the sliding rod, the trachea, and the pocket fabric positioning piece are connected as a whole to slide relative to the tongue pressing piece of the material, so that it is not easy for the trachea interface to fold, thereby increasing the service life of the trachea.

[0019] As a specific solution of the present invention, it may be preferred that: the top of the guide channel is an inclined guide surface.

[0020] Through the above arrangement, the airflow guiding capability is further improved, and the reliability of the negative pressure adsorption fabric is improved.

[0021] The technical effects of the present invention are mainly reflected in the following aspects: First, positive pressure exhaust is adopted, and negative pressure is formed at the cloth position by utilizing the airway and the guide channel, thereby quickly positioning the pocket cloth, and the stability, safety and working reliability are significantly improved; Second, the material sheet pressing tongue and the pocket cloth positioning member slide against each other to realize the formation and disappearance of the guide channel, complete the adsorption and release of the cloth, and the control is simple and the operation is stable; Third, the roller member and the waist-shaped groove are used in combination to realize the sliding guide.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below to make the technical solution of the present invention easier to understand and grasp, but it should not be understood as a limitation of the present invention.

[0029] Example:

[0030] A quick positioning negative pressure adsorption device, reference Figure 1 As shown, it includes a sheet tongue depressor 1, a pocket fabric positioning member 2, a tongue depressor fixing frame 3, and a telescopic mechanism 4 installed on the tongue depressor fixing frame 3 and driving the pocket fabric positioning member 2 to move horizontally. The pocket fabric positioning member 2 is slidably matched with the sheet tongue depressor 1, and a slide groove 31 is provided on the tongue depressor fixing frame 3. A slide rod 7 installed in the slide groove 31 is fixed on the pocket fabric positioning member 2, and the end of the slide rod 7 is fixedly connected to the telescopic mechanism 4. Through the cooperation of the slide groove 31 and the slide rod 7, the sliding action of the two is more stable and reliable. The telescopic mechanism 4 is a micro cylinder, the body of the micro cylinder is fixed on the tongue depressor fixing frame 3, and the telescopic rod of the micro cylinder is fixedly connected to the bottom surface of the slide rod 7. The installation method of the micro cylinder is concealed and can make more effective space.

[0031] Combination Figure 1 and Figure 2 As shown, a step block 23 is provided at the bottom of the pocket fabric positioning member 2, and the step block 23 is engaged with the edge of the material sheet tongue 1. The step block 23 can effectively locate the sliding position of the fabric positioning block to prevent excessive sliding, and on the other hand, can form a guide channel 5 with the material sheet tongue 1.

[0032] The tail of the pocket fabric positioning member 2 is provided with a plurality of mounting grooves 24 arranged along the direction of movement thereof, a roller member 6 is fixed on the mounting groove 24, and the tail of the sheet pressing tongue 1 is provided with a waist-shaped groove 11 for guiding and sliding the roller member 6. The plurality of mounting grooves 24 are provided to facilitate adjustment of the mounting position of the roller member 6, thereby adjusting the travel length of the roller member 6 in the waist-shaped groove 11. The roller member 6 moves in the waist-shaped groove 11 by rolling, thereby reducing friction resistance.

[0033] Continue to combine Figure 3 , Figure 4 and Figure 5 As shown, the pocket fabric positioning member 2 is provided with an air channel 21, a limit portion 22 hanging and extending toward the fabric direction, and a guide channel 5 located below the limit portion 22 and cooperating with the material sheet pressing tongue 1 to form a passage. The air outlet of the air channel 21 is below the limit portion 22 and sprays air toward the guide channel 5. The air channel 21, the limit portion 22, and the guide channel 5 are symmetrically arranged on both sides of the pocket fabric positioning member 2. The symmetrical distribution structure is adopted to make the adsorption force uniform and the positioning accurate.

[0034] The air channel 21 includes an air inlet 211 located above the pocket fabric positioning member 2, an air flow channel 212 that runs horizontally through the air inlet 211, and an air outlet 213 that is connected to the limiting portion 22. One end of the air flow channel 212 is blocked. As for the air flow channel 212: first, it is convenient for processing, so that the air inlet 211 and the air flow channel 212 can be connected; second, it is easy to clean. When in use, the air flow channel 212 is blocked, and it can be opened and unblocked when cleaning, and air can also be ejected therefrom. The top of the guide channel 5 is an inclined guide surface 51.

[0035] From the above, we can know the working process: the material tongue 1 is used to support the pocket fabric. In the initial state, the pocket fabric positioning member 2 fits against the material tongue 1. The air is ejected through the airway 21 and cooperates with the guide channel 5 to form a negative pressure below the limiter 22. The workers put the pocket fabric under the limiter 22, and the hanging and extended structure of the limiter 22 works, so that the pocket fabric can fit on the limiter 22. After that, the folding mechanism on the pocket pasting machine completes the folding of the pocket fabric, and the pocket tongue needs to be evacuated. Before that, stop the airflow, evacuate the pocket fabric positioning member 2 first, and then evacuate the fabric tongue.

[0036] It should be noted that the device for providing a source of compressed air is not shown in the drawings of this embodiment, but the source of compressed air can be provided by an air compressor or an air pump, and the connection between the air supplies is a flexible air pipe. It should be particularly pointed out that this solution uses the negative pressure formed by the positive air ejection, rather than a negative pressure generator.

[0037] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
