Description

Technical Field

[0001] The utility model relates to the technical field of valve bag processing, in particular to a valve bag processing device. Background Art

[0002] For example, patent announcement number CN220219917U discloses a cutting device for valve bag processing, which relates to the field of valve bag processing technology, including a machine and a cutting machine. The cutting machine is installed at the top of the machine, and a cutting knife is arranged at the bottom of the cutting machine. The left end of the cutting knife is fixedly connected to a fixing plate, and the top of the machine is fixedly connected to a support plate. A sliding rod is passed through and fixedly connected to the top of the support plate. A slide plate is slidably connected to the inner wall of the support plate. A guide rod is passed through and slides at the top of the slide plate, and a pressure plate is fixedly connected to the bottom of the guide rod. The above application sets a fixing plate on the outside of the cutting knife, so that the cutting knife can drive the slide plate to move down synchronously when it descends, and finally the rubber pad at the bottom of the pressure plate tightly squeezes the left and right sides of the part to be cut, so that the surface of the part to be cut maintains tension during the cutting process, so that the valve bag is not easy to shake when cutting, so as to achieve the effect of improving the cutting accuracy.

[0003] It clamps the two sides of the valve bag to be cut by two clamping plates, thereby ensuring that the bottom of the valve bag to be cut is unshaped. However, when the valve bag at the bottom of the cutting knife is in a loose state, the part of the valve bag to be cut is still in a relaxed state when the two clamping plates clamp the valve bag, which makes it inconvenient to stretch and tension the area to be cut when the cutting knife cuts the valve bag.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-4 A valve bag processing device shown in the figure includes a cutting table 1, a cutting frame 2 is installed on the top of the cutting table 1, a cutting knife 3 is installed in the internal transmission of the cutting frame 2, and an electrical appliance for driving the cutting knife 3 to move up and down is installed inside the cutting frame 2, so that the cutting knife 3 moves up and down to cut the valve bag on the cutting table 1, and a tensioning assembly 4 is symmetrically installed on the outside of the cutting frame 2.

[0027] In particular, the tensioning assembly 4 includes a mounting plate 41 and a mounting assembly 42, an extrusion plate 45, a stretching plate 43 and a guide column 44. The mounting plate 41 is vertically slidably mounted on the top of the cutting table 1 through the mounting assembly 42. The bottom of the guide column 44 is fixedly connected to the stretching plate 43. The top of the guide column 44 is tilted away from the cutting knife 3. A guide hole matching the guide column 44 is provided on the top of the mounting plate 41. The extrusion plate 45 is fixedly connected to the top of the side of the cutting knife 3. The extrusion plate 45 corresponds to the mounting plate 41. Since the guide column 44 is tilted, when the cutting knife 3 drives the extrusion plate 45 to descend, the extrusion plate 45 drives the mounting plate 41 to descend vertically. The mounting plate 41 first drives the stretching plate 43 to descend through the guide column 44, so that the bottom of the stretching plate 43 is pressed and fitted with the valve pocket. When the mounting plate 41 continues to descend, the mounting plate 41 slides relative to the guide column 44. Since the top of the guide column 44 is tilted away from the cutting knife 3, the guide When the column 44 slides relative to the mounting plate 41, the stretching plate 43 can slide horizontally away from the cutting knife 3, so that the two stretching plates 43 move away from each other, so that the valve bag to be cut area at the bottom of the cutting knife 3 is in a stretched state, and the force acting to stretch the valve bag to be cut area is the friction between the bottom of the stretching plate 43 and the valve bag, and the friction is related to the gravity of the stretching plate 43 and the friction torque between the mounting plate 41 and the guide column 44. The top of the guide column 44 is fixedly connected to the limiting block 46 through the guide hole, and a positioning block 47 is installed on the inner wall of the cutting frame 2. The positioning block 47 is located at the top of the stretching plate 43. The positioning block 47 is installed in the interior of the cutting frame 2 by internal bolts, and the width of the positioning block 47 is greater than the maximum distance between the two stretching plates 43. Therefore, when the mounting plate 41 rises, the positioning block 47 can limit the stretching plate 43 to prevent the stretching plate 43 from directly following the mounting plate 41 to rise through the guide column 44.

[0028] Furthermore, the mounting assembly 42 includes a fixed shell 421, a connecting plate 423 and a support spring 422. The fixed shell 421 is fixedly connected to the top of the cutting table 1, the connecting plate 423 is fixedly connected to the end of the mounting plate 41, the outer wall of the connecting plate 423 is slidably sleeved with the fixed shell 421, the support spring 422 is located at the bottom of the connecting plate 423, and the bottom of the inner wall of the fixed shell 421 is fixedly connected with a guide rod 424, the outer wall of the guide rod 424 is slidably sleeved with the connecting plate 423, the outer wall of the guide rod 424 is slidably sleeved with the support spring 422, and the elastic force of the support spring 422 acting on the mounting plate 41 through the connecting plate 423 is sufficient to support the weight of the mounting plate 41, the guide column 44 and the stretching plate 43, so that when the cutting knife 3 drives the extrusion plate 45 to rise, the support spring 422 can push the mounting plate 41 to rise and reset through the connecting plate 423.

[0029] Furthermore, a top plate 425 is provided on the top of the fixed shell 421, a connecting track 427 is fixedly connected to the top of the inner wall of the fixed shell 421, a connecting seat 426 is fixedly connected to the bottom of the top plate 425, the connecting seat 426 is horizontally slidably engaged with the outer wall of the connecting track 427, a limiting member 428 is provided for external sliding of the fixed shell 421, a clamping block 429 is fixedly connected to the bottom of the limiting member 428, the limiting member 428 can clamp and limit the top plate 425 through the clamping block 429 to ensure the stability of the top plate 425 installed on the top of the fixed shell 421, a clamping slot is provided on the top of the top plate 425, the outer wall of the clamping block 429 is slidably engaged with the inner cavity of the clamping slot, and a positioning plate is fixedly connected to the bottom of one side of the limiting member 428 4210, a sliding hole matching the positioning plate 4210 is provided on one side of the fixed shell 421, and a through hole matching the guide rod 424 is provided on the top of the positioning plate 4210. The positioning plate 4210 is located at the bottom of the support spring 422, and the support spring 422 can give the limit member 428 a downward limiting elastic force through the positioning plate 4210 to ensure the stability of the limit member 428 clamping the top plate 425. The limit member 428 is lifted and moved to separate the clamping block 429 from the top plate 425, and the top plate 425 is slid to be removed, and then the positioning block 47 that limits the stretching plate 43 can be disassembled, and the mounting plate 41 can be lifted and moved, so that the mounting plate 41 drives the connecting plate 423 to slide and separate from the fixed shell 421, so that it can be disassembled and maintained.
