Description

Technical Field

[0001] The utility model relates to the technical field of valve pocket processing, in particular to a fixture for valve pocket processing. Background Technique

[0002] A valve pocket is an internationally common packaging bag, mainly used for packaging powdered or granular solid materials such as edible powder, chemical powder, chemical fertilizer, synthetic materials, explosives, grain, salt, minerals, etc. and flexible items. In the processing of valve pockets, adhesives are needed to seal and bond them. Most small workshops in China usually use manual labor for this step. When processing, in order to prevent the valve pocket from moving randomly, fixtures are needed to fix it.

[0003] In existing small workshops, a rotating clamping plate is usually used to fix the valve pocket. When using it, workers need to repeatedly rotate the clamping plate by hand, resulting in excessive hand operations by workers, which is not convenient for improving processing efficiency. At the same time, when performing the bonding operation, the glue box needs to be directly placed on the workbench. Although it is convenient to operate, once accidentally touched during work, it may cause it to tip over, resulting in glue flowing out and polluting the workbench. Content of the Utility Model

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 - Figure 3 , the present invention provides a fixture for processing valve pockets, including a workbench 2 for supporting the overall device. The top of the workbench 2 is the working plane. The bottom of the workbench 2 is fixedly connected with support legs 3 for supporting the workbench 2. The right end of the support leg 3 is rotatably connected with a rotating shaft 4 for driving the pedal 5 to rotate. The outer wall of the rotating shaft 4 is fixedly connected with a pedal 5 for driving the transmission rod 7 to move. The top of the pedal 5 is rotatably connected with a connecting plate 6 for transmitting the movement of the pedal 5 to the transmission rod 7. The top of the connecting plate 6 is rotatably connected with a transmission rod 7 for driving the push rod 10 to move. By stepping on the pedal 5, the connecting plate 6 can be driven to move upward, and finally the transmission rod 7 is pushed to move upward. The top of the transmission rod 7 is fixedly connected with a push rod 10 for driving the pressing rod 12 to rotate. The bottom of the workbench 2 is fixedly connected with a support frame 9 for supporting the transmission rod 7 to prevent it from moving randomly. The transmission rod 7 slides on the right end of the support frame 9. The transmission rod 7 can move up and down at the right end of the support frame 9 and cannot randomly disengage from the right end of the support frame 9. The top of the workbench 2 is fixedly connected with a support plate 11 for supporting the pressing rod 12. The right end of the support plate 11 is rotatably connected with a pressing rod 12 for driving the pressing block 13 to move. The bottom of the pressing rod 12 is fixedly connected with a pressing block 13 for fixing the valve pocket. The top of the transmission rod 7 is fixedly connected with a return spring 8 for assisting the transmission rod 7 to reset. The top of the return spring 8 is fixedly connected to the bottom of the workbench 2. When the operator stops stepping on the pedal 5, the return spring 8 will squeeze the transmission rod 7 downward to make it move downward and reset. A groove 1 for placing valve pockets is opened at the top of the workbench 2. Before the gluing operation, multiple valve pockets can be placed on the top of the groove 1 in sequence. The push rod 10 penetrates and slides at the bottom of the workbench 2. The pressing rod 12 slides inside the push rod 10. When the push rod 10 moves upward, it drives the pressing rod 12 to rotate.

[0025] Furthermore, a rubber block 14 for fixing the glue box is fixedly connected to the inner wall of the workbench 2. A pull rod 15 is inserted through and slidably connected to the right end of the workbench 2 for driving the fixing block 17 to move left and right. The left end of the pull rod 15 is fixedly connected to a fixing block 17 for cooperating with the rubber block 14 to fix the glue box. The right end of the fixing block 17 is fixedly connected to a fixing spring 18 for driving the fixing block 17 to reset. The right end of the fixing spring 18 is fixedly connected to the inner wall of the workbench 2. The fixing spring 18 constantly presses the fixing block 17, causing it to constantly press the glue box to the left, preventing the glue box from moving randomly during use. The right end of the pull rod 15 is fixedly connected to a pull block 16 for facilitating the operator to move the pull rod 15.

[0026] In the present utility model, during use, the valve pockets to be adhered can be stacked on the top of the groove 1 in sequence. Subsequently, the pull block 16 is toggled to the right, driving the pull rod 15 to move to the right. While the pull rod 15 moves to the right, it drives the fixing block 17 to move to the right and compress the fixing spring 18, causing it to contract. At this time, the glue box can be placed at the position between the rubber block 14 and the fixing block 17. Subsequently, the pull block 16 can be slowly released. The fixing spring 18 will press the fixing block 17 to the left, causing it to move to the left to fix the glue box. At this time, the preparatory work before the operation is completed.

[0027] When starting the adhering work, when it is necessary to fix the valve pocket, the operator can first step on the pedal 5 to rotate the pedal 5. When the pedal 5 rotates, it drives the connecting plate 6 to move upward. While the connecting plate 6 moves upward, it presses the transmission rod 7 upward, causing it to move upward. When the transmission rod 7 moves upward, it drives the push rod 10 to move upward, and at the same time, it also presses the reset spring 8 upward, forcing it to contract. While the push rod 10 moves upward, it drives the pressure rod 12 to rotate. When the pressure rod 12 rotates, it drives the pressure block 13 to move synchronously. Finally, the pressure block 13 presses down on the top of the valve pocket. At this time, the valve pocket will be fixed. Subsequently, the adhering operation is started. When the topmost valve pocket is adhered, the pedal 5 can be slowly released. At this time, the reset spring 8 will press the transmission rod 7 downward, causing the transmission rod 7 to move downward to reset. At the same time, the push rod 10 will also be driven to move downward, and the pressure rod 12 will also be driven to rotate and reset. The pressure block 13 will also disengage from the top of the valve pocket, and the valve pocket will no longer be fixed. At this time, the adhered valve pocket can be removed, and preparations can be made to adhere the next valve pocket. During use, not only relying on the operator's hand operation, the operator can use hands and feet for the operation, which is more convenient during use and helps to improve the work efficiency of the adhering operation.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
