[0032] Reference below Figure 1 and Figure 4 The conveying module 100 according to the first aspect of the present invention will be described in detail.

[0033] refer to Figure 1 According to some embodiments of the present invention, the conveying module 100 includes a frame, a connecting component, a first adjusting component 140 and a second adjusting component 150, and the connecting component, the first adjusting component 140 and the second adjusting component 150 are all arranged on the frame.

[0034] The connecting component includes a first limiting structure 110, a second limiting structure 120 and a third limiting structure 130, the first limiting structure 110 and the second limiting structure 120 are distributed in the left-right direction, and the third limiting structure 130 is located between the first limiting structure 110 and the second limiting structure 120; the first limiting structure 110 and the second limiting structure 120 are both made of a flexible material that can be deformed under the action of an external force, the first adjustment component 140 is arranged on the left side of the first limiting structure 110 and is connected to the middle part of the first limiting structure 110, the second adjustment component 150 is arranged on the right side of the second limiting structure 120 and is connected to the middle part of the second limiting structure 120; the front end of the first limiting structure 110 forms a first end 110a, the rear end of the first limiting structure 110 forms a second end 110b, and the front end of the second limiting structure 120 forms The third end 121, the rear end of the second limiting structure 120 forms the fourth end 122, the front end of the third limiting structure 130 is the movable end 131, the rear end of the third limiting structure 130 is the fixed end 132, and the fixed end 132 is hinged on the frame, a first connecting port 101 is formed between the first end 110a and the third end 121, a second connecting port 102 is formed between the second end 110b and the fixed end 132, and a third connecting port 103 is formed between the fourth end 122 and the fixed end 132. The movable end 131 can swing left and right relative to the fixed end 132 under the action of external force. When the movable end 131 swings to the left to connect with the first end 110a, the first connecting port 101 is connected with the third connecting port 103. When the movable end 131 swings to the right to connect with the third end 121, the first connecting port 101 is connected with the second connecting port 102.

[0035] It should be noted that the first connecting port 101 and the second connecting port 102 are in a staggered state in the left-right direction. When the movable end 131 swings to the right to connect with the third end 121, the vertical distance between the middle part of the first limiting structure 110 and the third limiting structure 130 is smaller than the width distance between the first connecting port 101 and the second connecting port 102. In this case, when the containing bottle is transported from the first connecting port 101 to the second connecting port 102, although the containing bottle can enter the first connecting port 101 smoothly, the containing bottle is easily stuck in the position between the middle part of the first limiting structure 110 and the third limiting structure 130, thereby causing the bottle to be stuck, affecting the normal transportation of the containing bottle. similarly, the first connecting port 101 and the third connecting port 103 are in a staggered state in the left and right directions. When the movable end 131 swings to the left to connect with the first end 110a, the vertical distance between the middle part of the second limiting structure 120 and the third limiting structure 130 is smaller than the width distance between the first connecting port 101 and the third connecting port 103. In this case, when the containing bottle is transported from the first connecting port 101 to the third connecting port 103, although the containing bottle can smoothly enter the first connecting port 101, the containing bottle is easily stuck in the position between the middle part of the second limiting structure 120 and the third limiting structure 130, thereby causing the bottle to be stuck, affecting the normal transportation of the containing bottle.

[0036] In the conveying module 100 of the present embodiment, since the first limiting structure 110 and the second limiting structure 120 are both made of flexible materials that can undergo elastic deformation under the action of external force, and the first adjusting component 140 is connected to the middle part of the first limiting structure 110, and the second adjusting component 150 is connected to the middle part of the second limiting structure 120; when the movable end 131 swings to the right to connect with the third end 121, the staff can adjust the distance between the middle part of the first limiting structure 110 and the third limiting structure 130 through the first adjusting component 140 according to the specifications of the accommodating bottle, so that the accommodating bottle can be smoothly conveyed from the first connecting port 101 to the second connecting port 102; when the movable end 131 swings to the left to connect with the first end 110a, the staff can adjust the distance between the middle part of the second limiting structure 120 and the third limiting structure 130 through the second adjusting component 150 according to the specifications of the accommodating bottle, so that the accommodating bottle can be smoothly conveyed from the first connecting port 101 to the third connecting port 103.

[0037] It should be noted that the first limiting structure 110 needs to be able to deform under the adjustment of the first adjustment component 140 and needs to have a certain strength to limit the position of the containing bottle.

[0038] Based on the above reasons, in some embodiments of the present invention, reference Figure 2The first limiting structure 110 includes a rubber layer 111 and an elastic bracket 112 . The rubber layer 111 is connected to one end of the elastic bracket 112 close to the second limiting structure 120 . The first adjusting component 140 is connected to the elastic bracket 112 .

[0039] It can be understood that both the rubber layer 111 and the elastic bracket 112 can be deformed under the action of external force, and since the rubber layer 111 is relatively soft, it can play a buffering and protective role for the containing bottle. Since the elastic bracket 112 is relatively strong, it can improve the overall strength of the first limiting structure 110, so that the first limiting structure 110 has sufficient strength to limit the containing bottle.

[0040] It is understandable that, since the elastic bracket 112 is stronger than the rubber layer 111 , by connecting the first adjustment component 140 to the elastic bracket 112 , it is convenient for the staff to adjust the deformation degree of the first limiting structure 110 through the first adjustment component 140 .

[0041] Specifically, the elastic bracket 112 is an elastic metal bracket.

[0042] In order to realize the connection between the first adjustment component 140 and the elastic bracket 112, in a further embodiment of the present utility model, refer to Figure 2 A T-slot 112a is provided at one end of the elastic bracket 112 away from the rubber layer 111, and the extension direction of the T-slot 112a is parallel to the extension direction of the first limiting structure 110. A threaded connector 113 is slidably provided in the T-slot 112a. The first adjustment component 140 is partially penetrated in the T-slot 112a and is threadedly connected to the threaded connector 113.

[0043] It is understandable that, since the connection relationship between the first adjusting component 140 and the threaded connector 113 is a threaded connection, the first adjusting component 140 and the first limiting structure 110 are easily assembled and disassembled.

[0044] It can be understood that since the threaded connector 113 can be slidably disposed in the T-slot 112a, when the first adjustment component 140 is threadedly connected to the threaded connector 113, the staff can adjust the installation position of the first adjustment component 140 on the first limiting structure 110 according to actual needs, so that the staff can adjust the deformation degree of a specific position on the first limiting structure 110 through the first adjustment component 140.

[0045] In some embodiments of the present invention, reference Figure 3The first adjustment component 140 includes a mounting seat 141, a connecting member 142 and a locking member 143. The mounting seat 141 is arranged on the frame, and a mounting hole extending left and right is provided on the mounting seat 141. The connecting member 142 can be slidably penetrated into the mounting hole. A thread is provided at the right end of the connecting member 142. The right end of the connecting member 142 is threadedly connected to the threaded connecting member 113. A locking hole connected to the outside is provided on the hole wall of the mounting hole. The locking hole extends in a vertical direction. The upper end of the locking hole extends to the outside. The lower end of the locking hole is connected to the mounting hole. The locking member 143 is threadedly penetrated into the locking hole and partially extends into the mounting hole.

[0046] Furthermore, the staff can loosen the locking piece 143 upwards so that the connecting piece 142 can move relative to the mounting seat 141. At this time, the staff can drive the connecting piece 142 to move left and right to adjust the relative distance between the middle of the first limiting structure 110 and the third limiting structure 130. After the staff has adjusted the position of the connecting piece 142, the staff can tighten the locking piece 143 downwards. At this time, the locking piece 143 can cooperate with the hole wall of the mounting hole to lock and fix the connecting piece 142.

[0047] It should be noted that the specific structure of the second limiting structure 120 refers to the first limiting structure 110, the specific structure of the second adjustment component 150 refers to the first adjustment component 140, and the connection relationship between the second limiting structure 120 and the second adjustment component 150 refers to the connection relationship between the first limiting structure 110 and the first adjustment component 140.

[0048] In order to facilitate the connection between the movable end 131 and the first end 110a or the second end 110b, in some embodiments of the present invention, a first connecting structure is provided on the movable end 131, and a second connecting structure is provided on both the first end 110a and the third end 121, and the first connecting structure can be detachably connected to the second connecting structure.

[0049] Specifically, refer to Figure 1 and Figure 4 The first connection structure includes a first connection block 133 and a latch pin. The first connection block 133 is provided with a first latch pin hole, and the latch pin is inserted into the first latch pin hole. The second connection structure includes a second connection block 123. The second connection block 123 is provided with a second latch pin hole adapted to the latch pin. The first connection block 133 and the second connection block 123 are staggered in the vertical direction.

[0050] Furthermore, when it is necessary to realize the connection between the movable end 131 and the first end 110a, the staff can drive the movable end 131 to swing to the left so that the first connecting block 133 and the second connecting block 123 on the first end 110a are located on the same vertical line, and then the staff can insert the pin through the first pin hole and the second pin hole, thereby realizing the detachable connection between the movable end 131 and the first end 110a; when it is necessary to realize the connection between the movable end 131 and the second end 110b, the staff can drive the movable end 131 to swing to the right so that the first connecting block 133 and the second connecting block 123 on the second end 110b are located on the same vertical line, and then the staff can insert the pin through the first pin hole and the second pin hole, thereby realizing the detachable connection between the movable end 131 and the second end 110b.

[0051] Reference below Figure 1 The bottle conveying line of the second embodiment of the utility model is described in detail.

[0052] refer to Figure 1 According to the second embodiment of the utility model, the bottle conveying line includes the conveying module 100 of the first embodiment of the utility model.

[0053] In some embodiments of the present invention, reference Figure 1 The bottle conveying line further includes a main track 200 , a first sub-track 300 and a second sub-track 400 . The main track 200 is connected to the first connecting port 101 , the first sub-track 300 is connected to the second connecting port 102 , and the second sub-track 400 is connected to the third connecting port 103 .

[0054] It is understandable that the staff can move the movable end 131 of the third limiting structure 130 accordingly according to the specifications of the container bottles transported in the main track 200, so as to connect the first connecting port 101 with the second connecting port 102, or connect the first connecting port 101 with the third connecting port 103, thereby enabling the container bottles transported by the main track 200 to enter the first sub-track 300, or enter the second sub-track 400.

[0055] In a further embodiment of the present invention, reference Figure 1 A fourth limiting structure 210 and a fifth limiting structure 220 are respectively provided on the left and right sides of the main track 200, the first end 110a is connected to one end of the fourth limiting structure 210 away from the fifth limiting structure 220, the first end 110a and the fourth limiting structure 210 are surrounded to form a first avoidance gap 201 for accommodating the movable end 131, the third end 121 is connected to one end of the fifth limiting structure 220 away from the fourth limiting structure 210, the third end 121 and the fifth limiting structure 220 are surrounded to form a second avoidance gap 202 for accommodating the movable end 131.

[0056] It can be understood that when the movable end 131 swings to the left to connect with the first end 110a, due to the setting of the first avoidance gap 201, the movable end 131 can be accommodated in the first avoidance gap 201, so that the fourth end 122 and the movable end 131 can be smoothly connected, so as to reduce the probability that the movable end 131 hinders the container bottle from entering the first connecting port 101 from the main track 200; correspondingly, when the movable end 131 swings to the right to connect with the second end 110b, due to the setting of the second avoidance gap 202, the movable end 131 can be accommodated in the second avoidance gap 202, so that the fifth end and the movable end 131 can be smoothly connected, so as to reduce the probability that the movable end 131 hinders the container bottle from entering the first connecting port 101 from the main track 200.
