Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to the top knife mechanism of a packing machine and the core of a packing machine. Background Technology

[0002] A strapping machine, also known as a bundling machine or strapping machine, is a machine that uses strapping tape to wrap around products or packages, then tightens it and connects the ends by heat sealing or using fasteners. Its function is to ensure the strapping tape adheres tightly to the surface of the bundled goods, preventing the goods from scattering during transportation and storage due to loose strapping, while also ensuring a neat and aesthetically pleasing finish. The entire strapping process involves several steps: tape feeding, tape retraction, tightening, and heat sealing. These actions are primarily handled by the machine's mechanical core. Existing strapping machine mechanisms are complex, with the cutting unit divided into three parts, each controlled by a set of cams for lifting and lowering. For example, Chinese patent CN102086001A discloses a strapping machine mechanism that includes a heat-sealing and cutting mechanism with a heat-sealing plate mounted on a swing arm. This mechanism also includes a left blade and its mounting post, a middle blade and its mounting post, and a right blade and its mounting post. The left blade and its mounting post are separate, with the left blade detachably connected to the top of the mounting post. Alternatively, the middle blade and its mounting post are separate, with the middle blade detachably connected to the top of the mounting post. Alternatively, the right blade and its mounting post are separate, with the right blade detachably connected to the top of the mounting post. The left, middle, and right blades are raised and lowered by a left top-cutting cam, a middle top-cutting cam, and a right top-cutting cam, respectively. The packing machine top knife mechanism and packing machine core in this technology use many parts, are difficult to assemble, require high processing precision, and are costly. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by completely eliminating the complex structure of existing packaging machine mechanisms while achieving the functions of the original mechanism. This significantly reduces the number of parts used, simplifies the mechanism's structure, facilitates maintenance, and lowers costs.

[0004] The objective of this invention is achieved in the following manner: A top knife mechanism for a baling machine, comprising:

[0005] The top cutter sliding seat is disposed between two opposing support plates and is slidably connected to the support plates;

[0006] A top knife is located inside the top knife sliding seat, and the top knife is provided with a top knife strap hole for the packing strap to pass through;

[0007] A top cutter core block is disposed inside the top cutter and is slidably connected to the top cutter, and one end of the top cutter core block can enter the hole of the top cutter when sliding.

[0008] The cam mechanism drives the top cutter sliding seat, top cutter, and top cutter core block to rise and fall.

[0009] As an optional solution to the technical solution of the present invention, the top cutter includes a top cutter head and a top cutter shaft connected to the top cutter head;

[0010] The top cutter head is located above the top cutter sliding seat, and the top cutter shaft is slidably connected to the top cutter sliding seat;

[0011] The inner wall of the top cutter sliding seat is provided with a stepped surface, and a first spring is sleeved on the top cutter shaft between the stepped surface and the top cutter head;

[0012] The top cutter with holes is located on the top cutter head.

[0013] As an optional solution to the technical solution of the present invention, a second spring is connected to the bottom wall of the top cutter core block.

[0014] As an optional solution of the present invention, a third spring is provided between the bottom wall of the top cutter and the bottom wall of the top cutter core block, and the third spring is sleeved on the outside of the top cutter core block.

[0015] As an optional solution of the present invention, a roller is provided below the top knife sliding seat, and the roller contacts the cam of the cam mechanism.

[0016] In addition, the present invention also provides a packing machine core, including the packing machine top knife mechanism described above;

[0017] The hair-curling slide plate is slidably connected to the two support plates;

[0018] The first grooved plate is located below the end of the hot-roller slide near the packing strap;

[0019] The second grooved plate is disposed above the first grooved plate;

[0020] The ironing plate is connected to the second grooved plate;

[0021] A cutter is located at one end of the heating plate near the packing strap.

[0022] As an optional solution to the technical solution of the present invention, the hair-curling mechanism further includes:

[0023] A head baffle is located at the end of the second grooved plate away from the top knife mechanism of the baler.

[0024] As an optional solution to the technical solution of the present invention, the hair-curling mechanism further includes:

[0025] The pressure roller is located at one end of the heating plate near the packing strap.

[0026] As an optional solution to the technical solution of the present invention, the ironing head driving mechanism includes:

[0027] The drive motor provides the power for the movement of the ironing head mechanism and the top knife mechanism of the packaging machine;

[0028] A rotating wheel is located below the ironing head mechanism and is connected to the drive motor via a transmission system. When the drive motor is working, it drives the rotating wheel to rotate.

[0029] A rotating shaft is located at a non-center position of the rotating wheel, and a stop block is provided below the hair-curling slide. When the rotating wheel rotates, the rotating shaft applies a pushing force to the stop block, causing the hair-curling slide to move.

[0031] As an optional solution to the technical solution of the present invention, the end of the hot-rolling slide away from the packing strap is connected to the support plate by a fourth spring.

[0032] The beneficial effects of this invention are:

[0033] (1) The top knife mechanism of the packing machine of the present invention completely abandons the structure of the left, middle and right three knives used in the existing packing machine. It uses one knife to complete the fixing of the packing strap and the packing strap head, which greatly simplifies the structure, thereby reducing the failure rate and making maintenance relatively simple. The manufacturing cost and maintenance cost are greatly reduced.

[0034] (2) In this invention, the core of the packing machine drives the rotating wheel to rotate through the drive motor, and then pushes the heating head mechanism to move through the rotating shaft to complete a series of work such as heating and melting, pressing and cutting. Compared with the prior art, the structure of the core of the packing machine is simplified, and the packing efficiency is further improved. Attached Figure Description

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or a connection through an intermediate medium; it can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] like Figure 1 , Figure 2 As shown, the top knife mechanism of the baling machine includes: a top knife sliding seat 101, a top knife 102, a top knife core block 103, and a cam mechanism 108. The top knife sliding seat 101 is located between two opposing support plates 300 and is slidably connected to the support plates 300.

[0052] The top knife 102 is located inside the top knife sliding seat 101, and the top knife 102 is provided with a top knife belt hole 1023 for the packing strap to pass through; the top knife core block 103 is located inside the top knife 102 and is slidably connected to the top knife 102, and when the top knife core block 103 slides to the top, its upper end can enter the top knife belt hole 1023, squeezing the packing strap against the top wall of the top knife belt hole 1023; the cam mechanism 108 is used to drive the top knife sliding seat 101, the top knife 102 and the top knife core block 103 to rise and fall.

[0053] Specifically, in this example, the top knife mechanism of the strapping machine allows the strapping tape head to pass through the top knife tape hole 1023, then through the tape path, and finally through the top of the top knife 102. At this time, the cam of the cam mechanism 108 rotates, causing the top knife sliding seat 101 to slide upward. The top knife sliding seat 101 then causes the top knife 102 to move upward, pressing the strapping tape head between the top of the top knife 102 and the core of the strapping machine, thus fixing the strapping tape head. Then, the strapping machine's tape unwinding system works, tightening the strapping tape and binding the packaged items. At this time, the cam mechanism continues to work, causing the top knife core block 103 to continue to rise, pressing and fixing the strapping tape in the top knife tape hole 1023, which facilitates subsequent heat sealing and cutting.

[0054] As a further solution to this embodiment, such as Figure 2-4 As shown, the top cutter 102 includes a top cutter head 1021 and a top cutter shaft 1022 connected to the top cutter head 1021. The top cutter head 1021 is located above the top cutter sliding seat 101, and the top cutter shaft 1022 is slidably connected to the top cutter sliding seat 101. The inner wall of the top cutter sliding seat 101 is provided with a stepped surface, and a first spring 104 is sleeved on the top cutter shaft 1022 between the stepped surface and the top cutter head 1021. A top cutter belt hole 1023 is provided on the top cutter head 1021. When the top cutter sliding seat 101 continues to rise, the first spring 104 is compressed, so that the top of the top cutter 102 presses the packing strap head tightly.

[0055] Furthermore, a second spring 105 is connected to the bottom wall of the top knife core block 103. After the top knife 102 presses the packing tape head, the top knife sliding seat 101 continues to rise, contacts the second spring 105, compresses the second spring 105, and at the same time the second spring 105 pushes the top knife core block 103 to rise, pressing the packing tape located in the top knife tape hole 1023.

[0056] A third spring 106 is provided between the bottom wall of the top cutter 102 and the bottom wall of the top cutter core block 103, and the third spring 106 is sleeved on the outside of the top cutter core block 103.

[0057] To ensure the stability of the lifting of the top cutter slide seat 101 by the cam mechanism 108, a roller 107 is provided below the top cutter slide seat 101, and the roller 107 contacts the cam of the cam mechanism 108.

[0058] This example also provides the packing machine mechanism, such as... Figure 1 , Figure 5 As shown, the packaging machine includes the aforementioned top knife mechanism 100 and ironing head mechanism 200. Both the top knife mechanism 100 and the ironing head mechanism 200 are located between two opposing support plates 300. The top knife mechanism 100 is located on one side of the ironing head mechanism 200 and is slidably connected to one side support plate 300 via a slide plate 109. The ironing head mechanism 200 is slidably connected to both side support plates 300.

[0059] Specifically, such as Figure 6 , Figure 7 As shown, the ironing mechanism 200 includes: an ironing slide plate 201, a first grooved plate 206, a second grooved plate 209, an ironing plate 202, a head baffle 203, a cutter 204, and an ironing drive mechanism 205. Specifically: the ironing slide plate 201 is slidably connected to the two side support plates 300, used to drive the ironing plate 202, the head baffle 203, and the cutter 204 to move; the first grooved plate 206 and the second grooved plate 209 form a first channel for the packing strap exiting the top cutter hole 1023 to pass through; the second grooved plate 209 and the ironing slide plate 201 form a second channel for the packing strap head passing through the top of the top cutter 102; the ironing plate 202 is located at the front end of the second grooved plate 209 (in this example, according to...). Figure 6 "front" refers to Figure 6 The right side, the back refers to Figure 6(On the left side), when the heating head slide plate 201 moves backward, the heating head plate 202 is located between the end of the packing strap and the packing strap passing through the top knife hole 1023, and heats and melts the packing strap; the strap head baffle 203 is located at the end of the second groove plate 209 away from the top knife mechanism of the packing machine, and limits the packing strap end passing through the top of the top knife 102 to prevent the strap head from being too long and affecting the bonding effect; the cutter 204 is located at the end of the heating head slide plate 201 close to the packing strap, and cuts the heated, melted and bonded packing strap when the heating head slide plate 201 moves backward; the heating head drive mechanism 205 is used to drive the heating head mechanism 200 to slide.

[0060] To further improve the bonding effect of the packing straps, a pressure roller 207 is provided at one end of the heating plate 201 near the packing strap. When the heating plate 201 moves backward, it further presses the upper and lower packing straps that have been heated and melted to ensure the firmness of the bond.

[0061] As a further solution to this embodiment, such as Figure 8 As shown, the ironing head driving mechanism 205 includes: a drive motor 2051, a rotating wheel 2052, and a rotating shaft 2053. The drive motor 2051 is located on the outer side of a support plate 300, providing power for the movement of the ironing head mechanism 200 and the packing machine top knife mechanism 100. The rotating wheel 2052 is located below the ironing head mechanism 200 and is connected to the drive motor 2051 via a transmission system. When the drive motor 2051 operates, it drives the rotating wheel 2052 to rotate. The rotating shaft 2053 is located at a non-center position of the rotating wheel 2052. A stop block 210 is provided below the ironing head slide plate 201. When the rotating wheel 2052 rotates, it drives the rotating shaft 2053 to apply a pushing force to the stop block 210, causing the ironing head slide plate 201 to move. The drive shaft of the drive motor 2051 is connected to the cam mechanism 108.

[0062] In this embodiment, the transmission system is a gear transmission. Specifically, it includes a first gear 2054 connected to the drive shaft of the drive motor 2051, a second gear 2055 meshing with the first gear 2054, a first bevel gear 2056 connected to the second gear 2055 via a transmission shaft, a second bevel gear 2057 meshing perpendicularly with the first bevel gear 2056, and the second bevel gear 2057 being connected to the rotating wheel 2052 via a transmission shaft.

[0063] To ensure the ironing head mechanism 200 resets after completing the ironing and bonding work, the end of the ironing head slide plate 201 furthest from the packing strap is connected to the support plate 300 via a fourth spring 208. Alternatively, the fourth spring 208 can be omitted. In this case, the ironing head mechanism 200 can be moved by the forward and reverse rotation of the drive motor 2051. However, in this scenario, the cam mechanism needs to be designed to ensure coordination between the packing machine's top knife mechanism 100 and the ironing head mechanism 200.

[0064] The working principle of the packing machine mechanism in this embodiment:

[0065] Under the action of the strapping machine's feeding system, the strapping head passes through the top knife's tape hole 1023, then through the tape path, and finally through the top of the top knife 102. The tape head baffle 203 of the heating head mechanism 200 blocks the strapping head, and the feeding system stops feeding the tape. At this time, the drive motor 3501 moves the top knife 102 to rise, and the top knife 102 squeezes the strapping head between the top of the top knife 102 and the heating head slide plate 201 to fix the strapping head.

[0066] When the strapping machine's tape retraction system is working, it tightens the strapping tape to bind the packaged items. After the strapping tape is tightened, tape retraction stops, and the cam mechanism continues to work, driving the top knife core block 103 to rise and squeeze and fix the strapping tape in the top knife tape hole 1023.

[0067] The rotating shaft 2053 on the rotating wheel 2052 contacts the stop block 210, pushing the heating plate 201 to move backward, so that the heating plate 202 heats and melts the packing strap;

[0068] The rotating shaft 2053 continues to push to the stop block 210, causing the heating head slide plate 201 to move backward, the pressure roller 207 to press and bond the packing strap, and the cutter 204 to cut the packing strap that passes through the top knife hole 1023;

[0069] The rotating shaft 2053 on the rotating wheel 2052 passes through the outside of the stop block 210, and the fourth spring 208 pulls the heating plate 201 forward to reset it;

[0070] The top knife core block 103 descends, releasing the newly formed strapping head. The top knife 102 descends, releasing the strapping head at its top, thus completing the packaging process.

[0071] The top blade mechanism of the packing machine in this example completely abandons the structure of the left, middle and right three blades used in existing packing machines. It uses a single blade to complete the fixing of the packing strap and the packing strap head, making the structure simpler. In addition, the core of the packing machine in this example drives the rotating wheel to rotate through the drive motor, and then pushes the heating head mechanism to move through the rotating shaft to complete a series of work such as heating, melting, pressing and cutting. Compared with the existing technology, the structure of the packing machine core is simplified, and at the same time, the packing efficiency is further improved.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by the present invention.
