DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] 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 position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, a connection through an intermediate medium, or a communication between the two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0021] like Figure 1 , Figure 2 As shown, the top knife mechanism of the baler includes: a top knife sliding seat 101, a top knife 102, a top knife core block 103 and a cam mechanism 108. Among them: the top knife sliding seat 101 is arranged between two oppositely arranged support plates 300, and is slidably connected to the support plates 300; The top knife 102 is arranged inside the top knife sliding seat 101, and the top knife 102 is provided with a top knife belt hole 1023 for the strapping tape to pass through; the top knife core block 103 is arranged inside the top knife 102, and is slidably connected with the top knife 102, and the top knife core block 103 can enter the top knife belt hole 1023 when sliding upward, and the upper end of the top knife core block 103 can enter the top knife belt hole 1023, squeezing the strapping tape on 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.

[0022] Specifically, in the baler top knife mechanism of this example, the head of the strapping tape passes through the top knife belt hole 1023, and after passing through the belt path, passes through the top of the top knife 102. At this time, the cam of the cam mechanism 108 rotates, driving the top knife sliding seat 101 to slide upward, and the top knife sliding seat 101 drives the top knife 102 to move upward, squeezing the head of the strapping tape between the top of the top knife 102 and the baler movement, and fixing the head of the strapping tape; then the baler's belt unwinding system works, tightens the strapping tape, and bundles the packaged objects. At this time, the cam mechanism continues to work, driving the top knife core block 103 to continue to rise, squeezing and fixing the strapping tape in the top knife belt hole 1023, so as to facilitate subsequent hot gluing and cutting work.

[0023] As a further solution of this embodiment, Figure 2-4 As shown, the top knife 102 includes a top knife head 1021 and a top knife shaft 1022 connected to the top knife head 1021; the top knife head 1021 is located above the top knife sliding seat 101, and the top knife shaft 1022 is slidably connected to the top knife sliding seat 101; the inner wall of the top knife sliding seat 101 is provided with a step surface, and the top knife shaft 1022 between the step surface and the top knife head 1021 is provided with a first spring 104, and the top knife belt hole 1023 is provided on the top knife head 1021. When the top knife sliding seat 101 continues to rise, the first spring 104 is compressed, so that the top of the top knife 102 presses the strapping belt head.

[0024] Furthermore, the bottom wall of the top knife core block 103 is connected to a second spring 105. After the top of the top knife 102 presses the strapping 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, thereby pressing the strapping tape located at the top knife belt hole 1023.

[0025] A third spring 106 is provided between the bottom wall of the top knife 102 and the bottom wall of the top knife core block 103 , and the third spring 106 is sleeved on the outside of the top knife core block 103 .

[0026] In order to ensure the stability of the cam mechanism 108 in lifting the top knife sliding seat 101 , a roller 107 is provided below the top knife sliding seat 101 , and the roller 107 is in contact with the cam of the cam mechanism 108 .

[0027] This example also provides a baler movement, such as Figure 1 , Figure 5 As shown, the baler includes the above-mentioned baler top knife mechanism 100 and the ironing head mechanism 200, and both of the baler top knife mechanism 100 and the ironing head mechanism 200 are arranged between two oppositely arranged support plates 300, wherein the baler 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 through a slide plate 109, and the ironing head mechanism 200 is slidably connected to the support plates 300 on both sides.

[0028] Specifically, 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 plate 203, a cutter 204 and an ironing drive mechanism 205. Among them: the ironing slide plate 201 is slidably connected with the support plates 300 on both sides, and is used to drive the ironing plate 202, the head baffle plate 203 and the cutter 204 to move; the first grooved plate 206 and the second grooved plate 209 form a first belt path for the strapping tape coming out of the top knife belt hole 1023 to pass through, and a second belt path is formed between the second grooved plate 209 and the ironing slide plate 201 for the strapping tape head passing through the top of the top knife 102; the ironing plate 202 is arranged at the front end of the second grooved plate 209 (in this example, according to Figure 6 , "before" refers to Figure 6 The right side of Figure 6 On the left side), when the ironing slide plate 201 moves backward, the ironing plate 202 is located between the strapping tape head and the strapping tape passing through the top knife belt hole 1023, and the strapping tape is heated and melted; the strapping tape head baffle 203 is arranged at the end of the second belt groove plate 209 away from the top knife mechanism of the baler, and the strapping tape head passing through the top of the top knife 102 is limited to prevent the strapping tape head from being too long and affecting the bonding effect; the cutting knife 204 is arranged at the end of the ironing slide plate 201 close to the strapping tape, and the strapping tape that has been heated, melted and bonded is cut when the ironing slide plate 201 moves backward, and the ironing drive mechanism 205 is used to drive the ironing mechanism 200 to slide.

[0029] In order to further improve the bonding effect of the strapping tape, a pressing wheel 207 is provided at one end of the ironing slide plate 201 close to the strapping tape. When the ironing slide plate 201 moves backward, the upper and lower strapping tapes that have been heated, melted and bonded are further pressed together to ensure the firmness of the bonding.

[0030] As a further solution of this embodiment, Figure 8As shown, the ironing head driving mechanism 205 includes: a driving motor 2051, a rotating wheel 2052 and a rotating shaft 2053. Among them, the driving motor 2051 is arranged on the outer side of the supporting plate 300 on one side, and provides the power for the ironing head mechanism 200 and the top knife mechanism 100 of the baler to move; the rotating wheel 2052 is arranged below the ironing head mechanism 200, and is connected to the driving motor 2051 through the transmission system, and when the driving motor 2051 is working, it drives the rotating wheel 2052 to rotate; the rotating shaft 2053 is arranged at a non-center of the rotating wheel 2052, and a stopper 210 is arranged below the ironing head slide plate 201. When the rotating wheel 2052 rotates, it drives the rotating shaft 2053 to apply thrust to the stopper 210, so that the ironing head slide plate 201 moves; the driving shaft of the driving motor 2051 is connected to the cam mechanism 108.

[0031] In this embodiment, the transmission system is a gear transmission, specifically, including a first gear 2054 connected to the driving shaft of the driving motor 2051, a second gear 2055 meshingly connected to the first gear 2054, the second gear 2055 is connected to the first bevel gear 2056 through a transmission shaft, the first bevel gear 2056 is vertically meshed with the second bevel gear 2057, and the second bevel gear 2057 is transmission-connected to the rotating wheel 2052 through a transmission shaft.

[0032] In order to reset the ironing mechanism 200 after completing the ironing and gluing work, the end of the ironing slide plate 201 away from the strapping tape is connected to the support plate 300 through the fourth spring 208. Of course, the fourth spring 208 may not be provided. In the absence of the fourth spring 208, the ironing mechanism 200 can be moved by driving the motor 2051 in forward and reverse directions. Of course, in this case, the cam mechanism needs to be designed to ensure the coordination between the top knife mechanism 100 of the baler and the ironing mechanism 200.

[0033] The working principle of the baler movement of this embodiment: Under the action of the belt feeding system of the baler, the strapping tape head passes through the top knife belt hole 1023, passes through the belt path, and then passes through the top of the top knife 102. The strapping tape head is blocked by the strapping tape head baffle 203 of the ironing mechanism 200, and the belt feeding system stops feeding. At this time, the driving motor 3501 drives the top knife 102 to rise, and the top knife 102 squeezes the strapping tape head between the top of the top knife 102 and the ironing slide plate 201 to fix the strapping tape head. The strapping system of the baler works to tighten the strapping belt and bundle the packaged objects. After the strapping belt is tightened, the strapping belt stops being unwound, and the cam mechanism continues to work, driving the top knife core block 103 to rise, squeezing and fixing the strapping belt of the top knife belt hole 1023; The rotating shaft 2053 on the rotating wheel 2052 contacts the stopper 210, pushing the ironing plate 201 to move backward, so that the ironing plate 202 heats and melts the strapping tape; The rotating shaft 2053 continues to push to the stopper 210, so that the ironing slide plate 201 moves backward, the pressing wheel 207 presses and bonds the strapping tape, and the cutting knife 204 cuts the strapping tape passing through the top knife belt hole 1023; The rotating shaft 2053 on the rotating wheel 2052 passes through the outer side of the stopper 210, and the fourth spring 208 pulls the hair ironing slide plate 201 forward to reset; The top knife core block 103 descends to release the newly formed strapping tape head, and the top knife 102 descends to release the strapping tape head at its top to complete the strapping work.

[0034] The top knife mechanism of the baler of this example completely abandons the structure of the three knives of left, middle and right used in the existing baler, and only one knife is used to fix the baling tape and the baling tape head, and the structure is simpler. In addition, the baler movement of this example drives the rotating wheel to rotate through the driving motor, and then pushes the ironing head mechanism set on the rotating shaft to move, thereby completing a series of tasks such as heating, melting, pressing and cutting. Compared with the existing technology, the structure of the baler movement is simplified, and at the same time, the baling efficiency is further improved.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; 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 required by the present invention.
