Description

Technical Field

[0001] The invention relates to the field of condensed bead production equipment, and in particular to a main roller and cutter linkage device of a condensed bead packaging machine. Background Art

[0002] Gel beads are a product similar to beads that are made by wrapping one or more materials such as liquid, powder, granules, etc. in a thin film through a special process. Common ones include laundry beads, dishwashing beads, pesticide beads, etc. As people's demand for convenient and precise dosage products increases, gel beads are becoming more and more popular. Gel bead packaging machines have emerged to meet the needs of efficient and precise packaging of these products.

[0003] In the existing condensed bead packaging machine, after the condensed bead products are filled, sealed, and longitudinally cut on the main roller, the main roller continues to rotate to the cross-cutting station for cross-cutting. The cross-cutting process of the condensed bead products is generally driven by a cylinder to drive the cross-cutting knife forward to the cross-groove of the main roller to form a shearing action, and then the uncut products are cut horizontally to obtain the condensed bead products one by one. After cutting, the cylinder drives the cross-cutting knife to retract, and the main roller rotates to drive the next group of uncut products to rotate to the cross-cutting station, and the cross-cutting knife is driven by the cylinder to cut, and the cycle continues. However, because each time the cylinder drives the cross-cutting knife to move forward and retract, it takes an action time, in order to prevent the main roller from colliding with the cross-cutting knife, the main roller needs to stop rotating during this action time, thereby reducing the production efficiency of the product.

[0004] The Chinese patent "A pressure roller cross-cutting structure and packaging machine" with announcement number CN215476241U discloses the following content: "The driving structure is used to drive the cross-cutter to swing synchronously with the movement of the forming structure during cutting. Through this technical solution, the cross-cutter can swing synchronously with the movement of the forming structure during the cutting process to avoid the cross-cutter from colliding with the molds on both sides of the slot on the forming structure." That is, after the cylinder cuts in, the servo motor drives the cross-cutter to swing with the main roller to prevent the main roller from colliding with the cross-cutter. However, the electrical control of this structure is complex and the price is high. After the rotation speed of the main roller changes, the speed of the cross-cutter cannot be synchronized, resulting in the need to repeatedly debug the action parameters of the cross-cutter, reducing production efficiency. In addition, the problem of "large and small edges" of the condensed beads is easily caused by the asynchronous movement of the cross-cutter and the main roller, thereby reducing the production quality of the product. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a main roller and cross-cutting knife linkage device for a bead packaging machine, which can achieve the effect of follow-up cross-cutting, avoid the risk of collision between the main roller and the cross-cutting knife, reduce production costs, improve product production efficiency, and improve product production quality.

The output end of the first cylinder 404 is hinged to the middle of the L-shaped connecting rod 402, and the other end thereof is hinged to the housing 401, one end of the L-shaped connecting rod 402 is hinged to the housing 401, and the other end thereof is hinged to one end of the driven connecting rod 403, and the other end of the driven connecting rod 403 is hinged to the support plate 3, one side of the main roller 1 is connected to a cam plate 5, and the outer side of the cam plate 5 is arranged with a plurality of groups of concave and convex surfaces in a ring array, and one end of the L-shaped connecting rod 402 close to the driven connecting rod 403 is in contact with the concave and convex surface;

After cutting, due to the continuous rotation of the main roller 1 and the cam plate 5, the end of the L-shaped connecting rod 402 moves from the concave surface 8 to the convex surface 9 of the concave and convex surface, and then pushes the L-shaped connecting rod 402 to move backward, so that the driven connecting rod 403 drives the support plate 3 to slide downward along the arc guide rail 406 through the first slider 405, realizing the linkage between the main roller 1 and the cross-cutting mechanism 2, achieving the effect of follow-up cross-cutting, avoiding the collision between the main roller 1 and the cross-cutting knife 201, improving the production quality of the product, and reducing the production cost, and improving the production efficiency of the product.

When the sensor detects the positioning pin 6, the cross-cutting mechanism 2 is feedback-controlled to perform the cross-cutting action, thereby improving the accuracy of the cross-cutting action.

[0036] The purpose is that the second cylinder 202 drives the cross-cutting knife 201 to extend and retract through the mounting bracket 203, thereby controlling the cross-cutting knife 201 to cut and reset the product, thereby facilitating the cross-cutting action.

[0037] In order to improve the stroke accuracy of the cross-cutting action of the cross-cutting knife 201, in this embodiment, preferably, a linear guide rail 10 is connected to the support plate 3, and a second slider 11 is connected to the bottom of the mounting frame 203, and the second slider 11 is slidably connected to the linear guide rail 10;

[0038] The purpose is to drive the cross-cutting knife 201 to extend and retract while allowing the second slider 11 to slide along the linear guide rail 10 to improve the travel accuracy of the cross-cutting action of the cross-cutting knife 201.

[0039] In order to improve the resetting accuracy of the cross-cutting knife 201, in this embodiment, preferably, a proximity switch 12 for sensing the mounting frame 203 is installed on the support plate 3, and the proximity switch 12 is electrically connected to the second cylinder 202;

[0040] The purpose is to enable the proximity switch 12 to detect the position of the mounting frame 203 when the second cylinder 202 drives the cross-cutting knife 201 to retract through the mounting frame 203. When the proximity switch 12 detects the mounting frame 203, the feedback control of the second cylinder 202 stops driving, thereby improving the resetting accuracy of the cross-cutting knife 201.

[0041] In order to facilitate vertical cutting of the product, in this embodiment, preferably, a vertical cutting assembly 13 is provided above the cross-cutting mechanism 2, and the vertical cutting assembly 13 includes a vertical cutting knife 1301, a rotating shaft 1302 and a handle 1303.

A plurality of vertical cutting grooves 14 are provided on the main roller 1, and a plurality of vertical cutting knives 1301 are respectively embedded in the plurality of vertical cutting grooves 14.

[0042] The purpose is to rotate the rotating shaft 1302 through the handle 1303 before processing, and then embed a plurality of vertical cutting knives 1301 into a plurality of vertical cutting grooves 14 respectively. When the main roller 1 drives the product to rotate clockwise, the vertical cutting knives 1301 cut the product vertically.

[0043] In order to facilitate the overall movement of the cross-cutting mechanism 2, the linkage mechanism 4 and the vertical cutting assembly 13, in this embodiment, preferably, a mounting plate 15 is connected to the bottom of the housing 401, and the mounting plate 15 is connected to a third cylinder 16 for driving the translation thereof;

[0044] The purpose is to drive the mounting plate 15 to translate through the third cylinder 16, thereby driving the cross-cutting mechanism 2, the linkage mechanism 4 and the vertical cutting assembly 13 to move as a whole, so as to facilitate the cross-cutting mechanism 2 and the vertical cutting assembly 13 to reach the processing station.

[0046] The purpose is to press the product on the upper and lower sides of the cross-cutting knife 201 through the pressure roller 18 when the cross-cutting knife 201 cuts the product horizontally, so as to prevent the product from being elastically released instantly when being cut and causing the product to shrink significantly toward the uncut side, thereby improving the product production quality. During the process of pressing against the product, the pressure roller 18 will rotate along with the transportation of the product, thereby reducing relative friction and improving the smoothness of product transportation.

[0047] In order to facilitate the accurate positioning and installation of the cam disc 5, and thus improve the linkage accuracy of the cam disc 5 and the cross-cutting mechanism 2, in this embodiment, preferably, a plurality of strip grooves 19 are evenly arranged on the cam disc 5, and a first screw connected to the main roller 1 through a thread is provided on the strip groove 19, and a positioning protrusion 20 is connected to the inner side of the cam disc 5, and angle adjustment blocks 21 fixed to the main roller 1 are provided on both sides of the positioning protrusion 20, and the two angle adjustment blocks 21 are both connected to the second screws 22 through threads, and the opposite ends of the two second screws 22 are respectively abutted against the two sides of the positioning protrusion 20;

[0049] In order to improve the linkage smoothness between the main roller 1 and the cross-cutting mechanism 2, in this embodiment, preferably, one end of the L-shaped connecting rod 402 close to the driven connecting rod 403 is connected to a bearing 23 that abuts against the concave and convex surface;

[0050] The purpose is to keep the L-shaped connecting rod 402 in contact with the concave and convex surface of the cam plate 5 through the bearing 23. The bearing 23 will rotate along with the rotation of the cam plate 5 during the contact with the cam plate 5, thereby reducing relative friction and improving the linkage smoothness between the main roller 1 and the cross-cutting mechanism 2.

[0051] The working principle and use process of the present invention are as follows: a plurality of molds 24 for forming condensed bead products are arranged on the surface of the main roller 1, each mold 24 is loaded with a condensed bead product, the vertical cutting groove 14 is arranged between the left and right molds 24, and the horizontal cutting groove 7 is arranged between the upper and lower molds 24;

[0052] The third cylinder 16 drives the mounting plate 15 to translate, thereby driving the cross-cutting mechanism 2 and the vertical cutting assembly 13 to reach the processing station, and the handle 1303 rotates the rotating shaft 1302, thereby respectively inserting a plurality of vertical cutting knives 1301 into a plurality of vertical cutting grooves 14, and then the first cylinder 404 drives the L-shaped connecting rod 402 to swing, so that the L-shaped connecting rod 402 is kept in contact with the concave and convex surface of the cam plate 5 through the bearing 23, and the working position is reached at this time;

[0053] During operation, the main roller 1 is driven to rotate clockwise, and the main roller 1 drives the uncut products to rotate to the vertical cutting station, and the vertical cutting knife 1301 cuts the products vertically. The main roller 1 continues to drive the uncut products to rotate to the cross-cutting station. At this time, the sensor detects the positioning pin 6, and feedback controls the second cylinder 202 to drive the cross-cutting knife 201 to extend, so that the cross-cutting knife 201 cuts into the cross-cutting groove 7 to cut the uncut products. Before the cross-cutting knife 201 cuts into the cross-cutting groove 7, due to the continuous rotation of the main roller 1 and the cam plate 5, the end of the L-shaped connecting rod 402 moves from the convex surface 9 to the concave surface 8 of the concave-convex surface, thereby pushing the L-shaped connecting rod 402 to move forward, so that the driven connecting rod 403 drives the support plate 3 to slide upward along the arc guide rail 406 through the first slider 405;

[0054] After the cross-cutting knife 201 cuts into the cross-cutting groove 7, due to the continuous rotation of the main roller 1 and the cam plate 5, the end of the L-shaped connecting rod 402 moves from the concave surface 8 to the convex surface 9 of the concave-convex surface, thereby pushing the L-shaped connecting rod 402 to move backward, so that the driven connecting rod 403 drives the support plate 3 to slide downward along the arc guide rail 406 through the first slider 405, and then the cross-cutting mechanism 2 moves downward, realizing the linkage between the main roller 1 and the cross-cutting mechanism 2, achieving the effect of follow-up cross-cutting, and avoiding the collision between the main roller 1 and the cross-cutting knife 201. During the downward movement of the cross-cutting mechanism 2, the second cylinder 202 drives the cross-cutting knife 201 to retract, completing a cross-cutting action cycle.

[0055] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
