Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, and particularly relates to a pre-clamping device for a packaging machine prepared based on kraft paper. Background Technique

[0002] Kraft paper is a tough and water-resistant packaging paper, usually yellowish-brown in color, with high strength and burst resistance. When using kraft paper, a pre-clamping device for a packaging machine is used. The pre-clamping device for a packaging machine generally refers to a mechanical device used to fix or clamp packaging materials during the automated packaging process. The function of this device is to ensure that the packaging materials are in the correct position before the filling or encapsulation process, so as to accurately carry out subsequent packaging operations.

[0003] The existing pre-clamping device for a packaging machine used in the preparation of kraft paper does not have a buffering function, resulting in direct collision of the clamping knives, which causes damage to them over time.

[0004] Therefore, we propose a pre-clamping device for a packaging machine prepared based on kraft paper, which can buffer the clamping knives of the pre-clamping device for the packaging machine, avoid direct collision of the clamping knives, and extend the service life of the pre-clamping device for the packaging machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pre-clamping device for a packaging machine prepared based on kraft paper to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pre-clamping device for a packaging machine prepared based on kraft paper, including a frame body, an installation block fixedly installed on the outer wall of the frame body, and a processing component arranged outside the installation block. The processing component includes a buffering component arranged inside the frame body, and a pre-clamping component is arranged above the buffering component.

[0007] Preferably, the buffering component includes a sliding plate slidably arranged inside the frame body, a sliding rod slidably arranged inside the sliding plate, a spring sleeved on the outer wall of the sliding rod, a sliding frame fixedly installed at the end of the sliding rod, a sliding groove opened on the outer wall of the sliding frame, a first magnetic plate fixedly installed on the inner wall of the sliding groove, a second magnetic plate slidably arranged inside the sliding groove, and a clamping knife fixedly installed on the outer wall of the second magnetic plate.

[0008] Preferably, the pre-clamping component includes a connecting plate hinged to the outer wall of the sliding plate, a pressing frame hinged to the end of the connecting plate away from the sliding plate, a sleeve block fixedly installed inside the pressing frame, a limiting rod slidably arranged inside the sleeve block, a supporting block fixedly installed at the end of the limiting rod, and a telescopic rod fixedly installed at the bottom of the pressing frame.

[0009] Preferably, the second magnetic plate is magnetically repulsive to the first magnetic plate. The second magnetic plate is slidably arranged on the inner wall of the chute. Under the restriction of magnetic repulsion, the impact force of the clamping knife can be buffered.

[0010] Preferably, the sliding plate is in an I shape. There are two sliding plates, which are symmetrically distributed with respect to the center line of the frame body. The sliding plates moving towards each other can drive the clamping knife to move towards each other accordingly.

[0011] Preferably, the pressing frame is hinged to the sliding plate through a connecting plate. There are four connecting plates, which are divided into two groups and symmetrically distributed with respect to the center line of the top surface of the pressing frame. Supported by the connecting plates, the downward moving pressing frame can push the sliding plate through the connecting plates.

[0012] Preferably, the supporting block is fixedly installed on the outer wall of the frame body, and the end of the telescopic rod far from the pressing frame is fixedly installed on the top surface of the frame body. Supported by the supporting block, the limiting rod can stably limit the pressing frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The pre-clamping device of the packaging machine based on kraft paper preparation includes a buffer component as one of its components. When preparing kraft paper, the pre-clamping device will be used. First, the mounting block fixedly installed on the outer wall of the frame body is installed on the equipment. The pressing frame in the pre-clamping component drives two sliding plates to push towards each other through the connecting plates, so that the sliding plates drive the clamping knives to move towards each other to perform pre-clamping work. To extend the service life of the clamping knives, buffer treatment is required. When the sliding plates move towards each other, the sliding rods inside them will move accordingly. The springs sleeved on the outer walls of the sliding rods will move along with the sliding rods. The sliding frames fixedly installed at the ends of the sliding rods drive the second magnetic plates slidably arranged inside them and the clamping knives to move accordingly. When the two clamping knives come into contact, as the sliding plates continue to move, the clamping knives are clamped. The springs sleeved on the outer walls of the sliding rods are compressed by the sliding plates. Under the elastic action of the springs, pressure is applied to the outer walls of the sliding frames. This structure can prevent the two clamping knives from directly hitting each other. When the two clamping knives come into contact, as the sliding plates move towards each other, the clamping knives are squeezed, and the clamping knives drive the second magnetic plates to slide into the chutes opened on the outer walls of the sliding frames. Under the restriction of magnetic repulsion between the second magnetic plates and the first magnetic plates, the clamping knives can be buffered again. This structure can prevent the clamping knives from being directly damaged during pre-clamping, so as to extend the service life of the clamping knives (the clamping knives are common technical means in the art, so their structures are not fully described).

[0015] 2. The pre-clamping device of the packaging machine prepared based on kraft paper has a pre-clamping component as one of its parts. When pre-clamping work is required, the telescopic rod is activated, which drives the pressing frame to move downward. The connecting plate hinged to the bottom of the pressing frame pushes the sliding plate to move. Two groups of connecting plates can push the sliding plate towards each other. When the telescopic rod drives the pressing frame to move downward, the sleeve block fixedly installed inside the pressing frame slides on the outer wall of the limiting rod. Under the restriction of the limiting rod, the downward movement of the pressing frame can be made more stable. This structure can push the two sliding plates towards each other to perform the pre-clamping work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to have a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] A preferred embodiment of the pre-clamping device of the packaging machine prepared based on kraft paper provided by the present invention is as Figures 1 to 6 shown: A pre-clamping device of the packaging machine prepared based on kraft paper includes a frame body 1;

[0026] The outer wall of the frame body 1 is fixedly installed with a mounting block 2;

[0027] And a processing component 3 arranged outside the installation block 2. The processing component 3 includes a buffer component 31 arranged inside the frame 1. The buffer component 31 includes a sliding plate 311 slidably arranged inside the frame 1. A sliding rod 312 is slidably arranged inside the sliding plate 311. A spring 313 is sleeved on the outer wall of the sliding rod 312. A sliding frame 314 is fixedly installed at the end of the sliding rod 312. A chute 315 is opened on the outer wall of the sliding frame 314. A first magnetic plate 316 is fixedly installed on the inner wall of the chute 315. A second magnetic plate 317 is slidably arranged inside the chute 315. A clamping knife 318 is fixedly installed on the outer wall of the second magnetic plate 317.

[0028] In this embodiment, when preparing kraft paper, a pre-clamping device is used. First, the installation block 2 fixedly installed on the outer wall of the frame 1 is installed on the equipment. The pressing frame 322 in the pre-clamping component 32 drives two sliding plates 311 to push towards each other through the connecting plate 321, so that the sliding plates 311 drive the clamping knives 318 to move towards each other to perform the pre-clamping work. To extend the service life of the clamping knives 318, buffering treatment is required. When the sliding plates 311 move towards each other, the sliding rods 312 inside them are driven to move accordingly. The springs 313 sleeved on the outer walls of the sliding rods 312 are driven to move accordingly. The sliding frames 314 fixedly installed at the ends of the sliding rods 312 drive the second magnetic plates 317 slidably arranged inside them and the clamping knives 318 to move accordingly. When the two clamping knives 318 contact, as the sliding plates 311 continue to move, the clamping knives 318 are clamped. The sliding plates 311 compress the springs 313 sleeved on the outer walls of the sliding rods 312. Under the elastic action of the springs 313, pressure is applied to the outer walls of the sliding frames 314. This structure can prevent the two clamping knives 318 from directly colliding. When the two clamping knives 318 contact, as the sliding plates 311 move towards each other, the clamping knives 318 are squeezed, and the clamping knives 318 drive the second magnetic plates 317 to slide into the chutes 315 opened on the outer walls of the sliding frames 314. Under the magnetic repulsion restriction between the second magnetic plates 317 and the first magnetic plates 316, the clamping knives 318 can be buffered again. This structure can prevent the clamping knives 318 from being directly damaged during pre-clamping to extend the service life of the clamping knives 318 (the clamping knives 318 are common technical means in the art, so their structures are not fully described).

[0029] Further, the second magnetic plates 317 and the first magnetic plates 316 are magnetically repulsive. The second magnetic plates 317 are slidably arranged on the inner walls of the chutes 315. Under the magnetic repulsion restriction, the collision force of the clamping knives 318 can be buffered.

[0030] Furthermore, the sliding plates 311 are in an I shape. The number of the sliding plates 311 is two, which are symmetrically distributed with respect to the center line of the frame 1. The sliding plates 311 moving towards each other can drive the clamping knives 318 to move towards each other accordingly.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, a preferred embodiment of a pre-clamping device for a packaging machine prepared from kraft paper provided by the present utility model is as follows Figures 1 to 6 As shown: The pre-clamping assembly 32 includes a connecting plate 321 hinged to the outer wall of the sliding plate 311. One end of the connecting plate 321 away from the sliding plate 311 is hinged to a pressing frame 322. A sleeve block 323 is fixedly installed inside the pressing frame 322. A limiting rod 324 is slidably arranged inside the sleeve block 323. A support block 326 is fixedly installed at the end of the limiting rod 324. A telescopic rod 325 is fixedly installed at the bottom of the pressing frame 322.

[0033] In this embodiment, when pre-clamping work needs to be carried out, the telescopic rod 325 is started, which drives the pressing frame 322 to move downward. The connecting plate 321 hinged to the bottom of the pressing frame 322 pushes the sliding plate 311 to move. Two groups of connecting plates 321 can push the sliding plate 311 towards each other. When the telescopic rod 325 drives the pressing frame 322 to move downward, the sleeve block 323 fixedly installed inside the pressing frame 322 slides on the outer wall of the limiting rod 324. Under the limitation of the limiting rod 324, the downward movement of the pressing frame 322 can be made more stable. This structure can push the two sliding plates 311 towards each other to carry out pre-clamping work.

[0034] Furthermore, the pressing frame 322 is hinged to the sliding plate 311 through the connecting plate 321. The number of connecting plates 321 is four, divided into two groups, symmetrically distributed with respect to the center line of the top surface of the pressing frame 322. Supported by the connecting plates 321, the downward-moving pressing frame 322 can push the sliding plate 311 through the connecting plates 321.

[0035] In addition, the support block 326 is fixedly installed on the outer wall of the frame body 1, and one end of the telescopic rod 325 away from the pressing frame 322 is fixedly installed on the top surface of the frame body 1. Supported by the support block 326, the limiting rod 324 can stably limit the pressing frame 322.

[0036] The above is only a schematic specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present utility model shall fall within the scope of protection of the present utility model. Moreover, it should be noted that the various components of the present utility model are not limited to the above overall application. Each technical feature described in the specification of the present utility model can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present utility model should reasonably cover other combinations and specific applications related to the inventive points of this case.
