Description

Technical Field

[0001] This utility model relates to the field of sealing machines, and in particular to a manual sealing machine. Background Technology

[0002] A sealing machine, also known as a can sealing machine, is a commonly used device for sealing cans. It uses a sealing roller to press the can lid along the contour edge of the can to achieve a seal. Sealing machines come in both automatic and manual types. Manual sealing machines are widely used in the market due to their low cost. However, manual sealing machines have some inconveniences in use. For example, when sealing, the right hand is usually needed to rotate the drive handle to rotate the pressure head assembly and press the can lid, while the left hand is usually needed to hold the sealing machine body. Since there is currently no suitable grip on manual sealing machines on the market, operation is inconvenient. The operator can hold the column or base of the sealing machine with their left hand, which is inconvenient and also limits the appearance of the sealing machine. Utility Model Content

[0003] The purpose of this utility model is to provide a manual sealing machine with a simple structure and convenient gripping operation. This manual sealing machine includes a top plate, a bottom plate, and a column. The column is vertically connected between the top plate and the bottom plate. The top plate is connected to a drive handle, and the drive handle is connected to a pressure head assembly. Rotating the drive handle can drive the pressure head assembly to rotate. The bottom plate is connected to a tray assembly. The column is connected to a gripping unit. When the gripping unit is in use, the extension direction of the gripping unit forms an angle α with the extension direction of the column, where α is greater than or equal to 30 degrees. The column is provided with a locking hole, and one end of the gripping unit can be connected to the locking hole.

[0004] Furthermore, the gripping unit includes a collar and a grip handle. The collar is sleeved on the column, and a through hole is provided on the collar corresponding to the locking hole. One end of the grip handle can pass through the through hole and connect to the locking hole.

[0005] Furthermore, the grip includes a housing and an adapter, the adapter being rotatably connected to the housing and switchable between a first direction and a second direction relative to the housing, thereby switching the grip unit between a use state and a folded state.

[0006] Furthermore, the grip handle also includes a connecting part, one end of which is connected to the adapter, and the other end of which can pass through the through hole and connect to the locking hole.

[0007] Furthermore, the housing includes a first end face on the side near the adapter, and the adapter includes a second end face and a third end face. When the adapter is in a first direction relative to the housing, the second end face abuts against the first end face; when the adapter is in a second direction relative to the housing, the third end face abuts against the first end face.

[0008] Furthermore, the first end face, the second end face, and the third end face each include a plane.

[0009] Furthermore, the second end face and the third end face are perpendicular to each other.

[0010] Furthermore, a pin is connected through the inner side of the adapter, and a spring assembly is connected to the inner side of the housing. The spring assembly is kept in a stretched state so that the adapter remains connected to the housing when switching between the first direction and the second direction.

[0011] Furthermore, the connecting part includes a front section, a middle section, and a rear section. The front section and the rear section each include external threads. The front section can be screwed into the locking hole, and the rear section can be screwed into the adapter. The middle section is hexagonal in shape.

[0012] Furthermore, the third end face includes an opening that extends through the second end face and the third end face.

[0013] This manual sealing machine has the following advantages over existing technologies:

[0014] 1. This utility model relates to a manual sealing machine with a simple structure and convenient operation. A gripping unit is connected to the column, and the gripping unit includes a handle. The handle includes a housing and an adapter, which is rotatably connected to the housing. The adapter can switch between a first direction and a second direction relative to the housing, allowing the gripping unit to switch between a used state and a folded state. When the gripping unit is in use, its extension direction forms an angle α with the extension direction of the column, where α is greater than or equal to 30 degrees. When operating the sealing machine, place the can to be sealed on the tray assembly, rotate the drive handle with your right hand to rotate the pressure head assembly to crush the can lid, and hold the gripping unit with your left hand for easier sealing. When the sealing machine is not in use, rotate the housing so that the adapter is in the second direction relative to the housing, and the gripping unit is in the folded state, saving machine size, facilitating transportation and storage, and avoiding interference.

[0015] 2. The housing of this utility model includes a first end face on the side near the adapter. The adapter includes a second end face and a third end face. When the adapter is in a first direction relative to the housing, the second end face abuts against the first end face. When the adapter is in a second direction relative to the housing, the third end face abuts against the first end face. The second end face and the third end face are perpendicular to each other, so that when the grip unit is unfolded and in use, the extension direction of the grip unit is substantially perpendicular to the extension direction of the column. When the grip unit is folded and in the folded state, the extension direction of the grip unit is substantially parallel to the extension direction of the column. Attached Figure Description

[0023] See attached document Figures 1-4 This utility model discloses a manual sealing machine, comprising a top plate 1, a bottom plate 2, and uprights 3. The uprights 3 are vertically connected between the top plate 1 and the bottom plate 2. In this embodiment, three uprights 3 are included, forming a semi-enclosed shape with the opening facing the operator. The top plate 1 is connected to a drive handle 4, which is connected to a pressure head assembly 5. In this embodiment, the drive handle 4 is connected to the pressure head assembly 5 via a transmission gear (not shown). Rotating the drive handle 4 drives the pressure head assembly 5 to rotate. The bottom plate 2 is connected to a tray assembly 6, which is located directly below the pressure head assembly 5. The cans to be sealed can be placed on the tray assembly 6.

[0024] In this embodiment, the column 1 is connected to a gripping unit 70. The gripping unit 70 can be connected to any of the three columns in this embodiment. In this embodiment, to facilitate the use habits of most operators, the gripping unit 70 is connected to the leftmost column 3, such as... Figure 1 In actual operation, the operator holds the drive handle 4 with their right hand and rotates it, causing the pressure head assembly to rotate and crush the can lid. The left hand holds the gripping unit 70, making the sealing operation more convenient. When the gripping unit 70 is in use, its extension direction forms an angle α with the extension direction of the column 3, where α is greater than or equal to 30 degrees. In this embodiment, angle α is approximately 90 degrees, meaning that when the gripping unit 70 is in use, its extension direction is perpendicular to the extension direction of the column 3. The column 3 is provided with a locking hole 31, and one end of the gripping unit 70 can be connected to the locking hole 31.

[0025] In this embodiment, the gripping unit 70 includes a collar 701 and a grip handle 7. The collar 701 is sleeved on the column 3. A through hole 702 is provided on the collar 701 at the position corresponding to the locking hole 31. One end of the grip handle 7 can pass through the through hole 702 and be connected to the locking hole 31.

[0026] In this embodiment, the grip handle 7 includes a housing 71 and an adapter 72. The adapter 72 is rotatably connected to the housing 71. The adapter 72 can switch between a first direction D1 and a second direction D2 relative to the housing 71, so that the grip unit 70 can switch between a use state and a folded state. The first direction D1 is the direction when the grip unit 70 is in the use state, and the second direction D2 is the direction when the grip unit 70 is in the folded state.

[0027] In this embodiment, the grip handle 7 further includes a connecting portion 73. One end of the connecting portion 73 is connected to the adapter 72, and the other end of the connecting portion 73 can pass through the through hole 702 and connect to the locking hole 31. In this embodiment, the connecting portion 73 includes a front section 731, a middle section 732, and a rear section 733. The front section 731 and the rear section 733 each have external threads. The front section 731 can be screwed into the locking hole 31, and the rear section 733 can be screwed into the adapter 72. The middle section 732 is hexagonal in shape. When connecting the grip handle 7 to the column, first pass the front section 731 through the through hole 702 on the collar 701, and rotate the grip handle 7 so that the front section 731 is screwed into the locking hole 31. To further ensure the connection stability, an Allen wrench can be used to tighten the middle section 732.

[0028] In this embodiment, the side of the housing 71 near the adapter 72 includes a first end face 711, and the adapter 72 includes a second end face 721 and a third end face 722. When the adapter 72 is in a first direction D1 relative to the housing 71, the second end face 721 abuts against the first end face 711; when the adapter 72 is in a second direction D2 relative to the housing 71, the third end face 722 abuts against the first end face 711. In this embodiment, the first end face 711, the second end face 721, and the third end face 722 each include a plane, which facilitates stable abutment. The first end face 711, the second end face 721, and the third end face 722 can each be entirely plane or partially plane. When the plane of the second end face 721 abuts against the plane of the first end face 711, without rotating the housing 71 or the adapter 72, the two end faces can stably abut together, facilitating stable operation and use. In this embodiment, the second end face 721 and the third end face 722 are perpendicular to each other. When the gripping unit 70 is unfolded and in use, the extension direction of the gripping unit 70 is approximately perpendicular to the extension direction of the column. When the gripping unit 70 is folded, the extension direction of the gripping unit 70 is approximately parallel to the extension direction of the column 3. This prevents the gripping unit 70 from protruding too much from the column 3, thus saving space occupied by the sealing machine.

[0029] In this embodiment, the housing 71 and the adapter 72 each have cavities. A pin 723 is connected through the inner side of the adapter 72. A spring assembly 74 is connected to the inner side of the housing 71 via the pin 723. One end of the spring assembly 74 is connected to the pin 723, and the other end is connected to the inner side of the housing 71. The spring assembly 74 is kept in a stretched state so that the adapter 72 remains connected to the housing 71 when switching between the first direction D1 and the second direction D2. In this embodiment, the third end face 722 includes an opening 724 that passes through the second end face 721 and the third end face 722. When the adapter 72 is in the second direction D2 relative to the housing 71, the third end face 722 abuts against the first end face 711. At this time, the spring assembly 74 can be located between the openings 724, thereby allowing the third end face 722 to better abut against the first end face 711 and avoiding interference between the spring assembly 74 and the adapter 72.

[0030] In actual operation, first confirm whether the gripping unit 70 is in use, that is, confirm whether the extension direction of the gripping unit 70 is approximately perpendicular to the extension direction of the column 3. If the gripping unit 70 is in a folded state, then hold the housing 71 and apply a certain force to the housing 71 away from the adapter 72, that is, pull the housing 71 away from the adapter 72 a certain distance, and then rotate the housing 1 so that the housing 71 and the adapter 72 rotate relative to each other until the second end face 721 abuts against the first end face 711, and the adapter 72 is facing the first direction D1 relative to the housing 71. At this time, the gripping unit 70 is in use. Next, place the can to be sealed on the tray assembly 6, hold the drive handle 4 with your right hand and the gripping unit 70 with your left hand, and rotate the drive handle 4 with your right hand. Under the action of the drive handle 4, the pressure head assembly 5 also rotates. During the continuous rotation process, the pressure head assembly crushes the can lid to complete the sealing operation of the can. When the sealing machine is not needed, the gripping unit 70 can be folded into a folded state. Specifically, hold the housing 71 and apply a certain force to the housing 71 away from the adapter 72, i.e., pull the housing 71 a certain distance away from the adapter 72. At this time, the second end face 721 disengages from the first end face 711. Under the action of the spring assembly 74, the adapter 72 and the housing 71 remain connected. Then rotate the housing 1 so that the housing 71 and the adapter 72 rotate relative to each other until the third end face 722 abuts against the first end face 711. At this time, the adapter 72 is oriented in the second direction D2 relative to the housing 71, and the gripping unit 70 is in a folded state. In the folded state, the extension direction of the housing 71 is roughly parallel to the extension direction of the column 3, so that the gripping unit 70 does not protrude too much from the column 3, saving space occupied by the sealing machine and facilitating its storage.

[0031] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
