Description

Technical Field

[0001] This utility model relates to the field of bending processing equipment, and in particular to a bending and pressing device. Background Technology

[0002] In the process of bending and sealing the opening of packaging bags (especially those made of plastic materials such as tin foil and aluminum foil), manual or simple mechanical methods are often used for bending and pressing. Traditional manual methods are inefficient and inconsistent, and uneven force can easily lead to bag deformation or insecure sealing. Utility Model Content

[0003] The purpose of this invention is to provide a bending and pressing device to solve the problem of low sealing efficiency of packaging bags in the prior art.

[0004] The technical solution of this utility model is: a bending and pressing device, including a base, on which a first bending mechanism, a second bending mechanism and a material pushing mechanism are arranged. The pushing mechanism has a pusher and a pusher driver. The pusher can contact the product and, driven by the pusher driver, move the product toward the first bending mechanism and the second bending mechanism in sequence, so that the product has a first bending station and a second bending station. The first bending mechanism has a first bending part and a first bending driver. The first bending part has a projection that partially overlaps with the product at the first bending station on a plane parallel to the product. Under the drive of the first bending driver, the bending part moves from a first relative position of the product to a second relative position, so that the product forms a body and a pre-folded part that folds relative to the body. The second bending mechanism has a second bending portion and a second bending driver. The second bending portion has a projection that partially coincides with the pre-bending portion on a plane parallel to the pre-bending portion, and has a projection that partially or completely coincides with a plane parallel to the body relative to the pre-bending portion in the second bending station.

[0005] Preferably, the first bending mechanism and the second bending mechanism are arranged in a horizontal direction, and the first bending driver and the second bending driver respectively drive the first bending part and the second bending part to move in a vertical direction.

[0006] Preferably, a sliding table is provided on the base, and the product moves along the sliding table under the drive of the pushing mechanism; The first bending part is constructed as a plate-shaped structure. The first bending part is placed at the end of the sliding table, and the first bending part has a first station and a second station under the drive of the first bending driver. In the first station, the upper surface of the first bending part has a height not higher than the upper surface of the sliding table.

[0007] Preferably, a positioning mechanism is provided in conjunction with the first bending mechanism. The positioning mechanism includes a positioning pressure plate and a positioning driver. The positioning pressure plate abuts against the upper surface of the product under the drive of the positioning driver, and the edge of the positioning pressure plate near the first bending part is used to form the fold line of the product body and the pre-folding part.

[0008] Preferably, the first bending section is provided with a bending floating block for lifting and lowering. When the first bending section is in the second working position, the bending floating block has an upper surface that is flush with the sliding table.

[0009] Preferably, the sliding table is provided with a guide adjustment mechanism on both sides. The guide adjustment mechanism includes guide plates symmetrically arranged relative to the sliding table. The pair of guide plates open and close under the action of the adjuster, so that they can fit against the sides of the product, and the pair of guide plates cooperate with the sliding table to form a channel for the product to pass through.

[0010] Preferably, the pusher includes a pusher bracket connected to the pusher driver, a pusher block is provided at the end of the pusher bracket away from the pusher driver, and a V-groove is provided at the end of the pusher block away from the pusher bracket.

[0011] Preferably, a buffer is provided between the pusher block and the pusher bracket, and the two ends of the buffer abut against the pusher block and the pusher bracket respectively.

[0012] Compared with the prior art, the advantages of this utility model are: (1) The first bending mechanism and the second bending mechanism are used in steps to initially fold the part to form a pre-fold before pressing it. The sealing process is smooth and consistent, which effectively improves the sealing quality.

[0015] The present invention will be further described in detail below with reference to specific embodiments: A bending and pressing device is used to bend and seal the opening of packaging bags made of plastic materials such as tin foil and aluminum foil.

[0016] like Figure 1 and Figure 2 As shown, it includes a base 1, on which a pushing mechanism 2, a positioning mechanism 3, a first bending mechanism 4, and a second bending mechanism 5 are arranged sequentially along the horizontal direction.

[0017] The base 1 has a sliding table 11 mounted on its upper surface, and the product is placed on the sliding table 11. The pushing mechanism 2 has a pusher 21 and a pusher driver 22. The pusher 21 can contact the product and, driven by the pusher driver 22, pushes the product to the sliding table 11 in sequence towards the first bending mechanism 4 and the second bending mechanism 5, so that the product has a first bending position and a second bending position.

[0018] Specifically, such as Figure 3 As shown, the pusher 21 includes a pusher bracket 211 connected to the pusher driver 22. A pusher block 212 is provided at one end of the pusher bracket 211 away from the pusher driver 22, and a V-groove 213 is provided at the other end of the pusher block 212 away from the pusher bracket 211. The V-groove 213 is horizontally oriented and used to abut against the product. In this embodiment, the pusher driver 22 is composed of a motor and a lead screw.

[0019] Furthermore, a buffer 214 is provided between the pusher block 212 and the pusher bracket 211. The buffer 214 consists of a guide rod and a spring sleeved on the guide rod. The two ends of the spring abut against the pusher block 212 and the pusher bracket 211 respectively, to buffer the pushing force on the product. One end of the guide rod is fixed to the pusher bracket 211, and the other end is slidably disposed in the pusher block 212 to guide the movement of the spring.

[0020] Combination Figure 4 As shown, the first bending mechanism 4 has a first bending section 41 and a first bending driver 42. The first bending section 41 is a plate-shaped structure and is located at the end of the sliding table 11. The first bending section 41 can perform vertical lifting and lowering movements under the drive of the first bending driver 42, and has a first working position in its normal state and a second working position after being raised. Furthermore, in the first working position, the upper surface of the first bending section 41 is flush with the upper surface of the sliding table 11, so that the head end of the product entering the first bending working position can fit against the first bending section 41.

[0021] Combination Figure 5 As shown, when the first bending part 41 rises from the first station to the second station under the drive of the first bending driver 42, the first bending part 41 will move from the bottom of the product to the top of the product, and in the process, it will slide against the product and fold the head end of the product upward, so that the product forms the main body and the pre-folded part that folds relative to the main body.

[0022] The positioning mechanism 3 includes a positioning plate 31 and a positioning driver 32. The positioning plate 31, driven by the positioning driver 32, abuts against the upper surface of the product, pressing the product onto the sliding table 11 to prevent displacement of the product when the first bend 41 moves upward. In addition, the edge of the positioning plate 31 near the first bend 41 can also be used to form the fold line of the product body and the pre-fold.

[0023] Furthermore, in combination Figure 6 As shown, after the first bending section 41 rises from the lower first station to the second station, the product will lack support at the position corresponding to the first station as it moves towards the second bending station, affecting the stability of the pushing action. Therefore, this application provides a bending floating block 6 to cooperate with the lifting of the first bending section 41. The bending floating block 6 can move up and down under the drive of a corresponding driving mechanism. When the first bending section 41 is at the first station, the bending floating block 6 is built into the base 1; when the first bending section 41 rises to the second station, the bending floating block 6 rises to have an upper surface flush with the sliding table 11, which is used to fill the gap at the first station and achieve stable support for the product.

[0024] Combination Figure 7As shown, the second bending mechanism 5 has a second bending section 51 and a second bending driver 52. The second bending section 51 is also configured as a plate-like structure, capable of lifting and lowering under the drive of the second bending driver 52. Furthermore, the height of the highest point of the lifting and lowering movement of the second bending section 51 does not exceed the length of the pre-folded part of the product, so that the pre-folded part can abut against the second bending section 51 during the process of the product entering the second bending station, causing the pre-folded part to fold further towards the body. At this time, the angle between the pre-folded part and the body will be less than 90°.

[0025] After the product enters the second bending station, the second bending part 51 and the pre-bending part have overlapping projections on the horizontal plane. Then, the second bending driver 52 drives the second bending part 51 to press down the pre-bending part, so that the pre-bending part fits into the body, completing the sealing of the product.

[0026] In this embodiment, both the first bending actuator 42 and the second bending actuator 52 are cylinders.

[0027] In addition, guide adjustment mechanisms are provided on both sides of the sliding table 11. The guide adjustment mechanisms include guide plates 7 symmetrically arranged relative to the sliding table 11. The pair of guide plates 7 can fit against the sides of the product and cooperate with the sliding table 11 to form a channel for the product to pass through. Furthermore, the pair of guide plates 7 open and close under the action of the adjuster, thereby accommodating products of different widths and sizes.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
