Description

Technical Field

[0001] This application relates to the field of waste collection technology, and in particular to a waste collection device for blister packs. Background Technology

[0002] In the production of blister trays, the material strip is first heated to soften it. After softening, the material strip is vacuum-formed. Then, the material strip is conveyed to the punching device to cut the formed blister tray off the material strip. The winding roller then winds up the waste material on the material strip.

[0003] Because the length of the strip is limited, once a roll of strip is completely used up and the take-up roller has finished winding up all the waste material, the waste material on the take-up roller needs to be removed for recycling before the next roll of waste material can be wound up.

[0004] However, during the winding process, the winding roller needs to tension the waste material to facilitate winding, which makes it inconvenient to operate when removing the waste material. Summary of the Invention

[0005] To address the problem of inconvenience in removing waste materials, this application provides a waste collection device for blister packs.

[0006] This application provides a waste collection device for blister trays, which adopts the following technical solution: A waste collection device for blister trays includes a movable rod and tension bars disposed on both sides of the movable rod. The movable rod is provided with an adjustment component, which is connected to the tension bars. The adjustment component is used to adjust the distance between the tension bars on both sides of the movable rod, so that the tension bars on both sides move closer to each other or further apart.

[0007] By adopting the above technical solution, the distance between the tension bars on both sides is adjusted by the adjustment component. When the waste material is wound up, the distance between the tension bars on both sides is the largest. After the winding is completed, the adjustment component drives the tension bars on both sides to move closer to each other, which makes it easy to remove the wound waste material from the tension bars, and the operation is convenient.

[0008] In one specific implementation, the adjusting assembly includes a fixed block mounted on the movable rod, with adjusting blocks rotatably connected to both sides of the fixed block. The adjusting blocks rotate unidirectionally with the fixed block, and the adjusting blocks are rotatably connected to the tension bar.

[0009] By adopting the above technical solution, when the movable rod is pushed, the fixed block is moved to the extreme position where the fixed block and the adjusting block are parallel and the fixed block and the adjusting block are perpendicular to the tension bar. At this point, there will be no more relative rotation between the fixed block and the adjusting block, which allows the tension bar to tension the waste material, making it easier to collect the waste material.

[0010] In one specific implementation, a rotating shaft is coaxially mounted inside the movable rod. One end of the rotating shaft is provided with a limiting block. The diameter of the limiting block is larger than the distance between the outer walls of the tensioning strips on both sides of the movable rod. The other end of the movable rod is provided with a limiting component, which is used to limit the waste material on the tensioning strip.

[0011] By adopting the above technical solution, the waste material is wound on the tension bar, and the waste material is limited by the limiting block and limiting component to avoid the waste material from shifting during the winding process, thereby achieving a better winding effect for the waste material.

[0012] In one specific implementation, a limiting cavity is formed in the limiting block, the movable rod extends into the limiting cavity, a push plate is provided in the limiting block, the push plate is mounted on the movable rod, a discharge rod is provided on the side wall of the push plate facing the tension bar, and a through groove is formed on the side wall of the limiting block facing the tension bar for the discharge rod to pass through.

[0013] By adopting the above technical solution, pulling the movable rod brings the tension bars on both sides closer together. The movable rod can then drive the push plate to move, and the push plate will drive the discharge rod through the through groove, pushing the waste material on the tension bar. This makes it easier to remove the waste material from the tension bar and helps to improve work efficiency.

[0014] In one specific implementation, the limiting component includes a transition strip and a limiting strip disposed on both sides of the movable rod. The transition strip is rotatably connected to the end of the tensioning strip away from the limiting block, and the limiting strip is rotatably connected to the end of the transition strip away from the tensioning strip. The maximum distance between the limiting strips on both sides is greater than the maximum distance between the tensioning strips on both sides. The rotating shaft is provided with a telescopic component for adjusting the distance between the limiting strips on both sides of the movable rod.

[0015] By adopting the above technical solution, since the maximum distance between the limit strips on both sides is greater than the maximum distance between the tension strips on both sides, the limit strips can limit the waste material. By setting the telescopic component, when it is necessary to remove the waste material on the tension strip, the limit strips on both sides can be brought closer to each other through the telescopic component, and then the tension strips can be brought closer to each other, which makes it easy to remove the waste material and is convenient to operate.

[0016] In one specific implementation scheme, the telescopic component includes a telescopic sleeve, a telescopic block, and a connecting block. A sliding groove is provided on the inner wall of the telescopic sleeve. A sliding block is provided at one end of the movable rod near the telescopic sleeve, and the sliding block is slidably installed in the sliding groove. The telescopic block is installed on the telescopic sleeve, and the connecting block is rotatably connected to both sides of the telescopic sleeve. The connecting block is rotatably connected to the limiting strip.

[0017] By adopting the above technical solution, the telescopic sleeve moves, which in turn moves the telescopic block, causing relative rotation between the telescopic block and the connecting block. This allows the connecting block to move the limit strips on both sides closer together, making it easier to remove the waste material from the tension strip. The operation is convenient.

[0018] In one specific implementation scheme, a positioning sleeve is slidably fitted onto the telescopic sleeve, a positioning groove is formed on the inner wall of the positioning sleeve, a positioning block is provided on the outer wall of the telescopic sleeve, the positioning block is slidably installed in the positioning groove, positioning plates are provided on both sides of the positioning sleeve, the positioning plates are used to limit the relative position between the telescopic block and the connecting block, and a rotating sleeve is threaded onto the telescopic sleeve, the rotating sleeve is used to limit the telescopic sleeve.

[0019] By adopting the above technical solution, by setting a positioning sleeve and moving the positioning sleeve, when the positioning plate on the positioning sleeve contacts the telescopic block and the connecting block, the relative rotation between the telescopic block and the connecting block can be restricted. Then, the rotating sleeve is pressed against the positioning sleeve to position the positioning sleeve, so that the limit strips on both sides remain in an open state. During the process of winding up the waste material, the telescopic sleeve remains stable, thereby achieving a better winding effect.

[0020] In one specific implementation scheme, an annular groove is formed on the outer wall of the positioning sleeve, a rotating groove is formed on the outer wall of the rotating sleeve, and a connecting rod is provided between the positioning sleeve and the rotating sleeve, with one end of the connecting rod disposed in the annular groove and the other end disposed in the rotating groove.

[0021] By adopting the above technical solution, when the rotating sleeve comes into contact with the positioning sleeve, the rotating sleeve pushes the positioning sleeve to move closer to the telescopic component, thus pressing the telescopic component against it; when the rotating sleeve is rotated in the opposite direction, the rotating sleeve can drive the positioning sleeve to move away from the telescopic component, thereby allowing the limit strips on both sides to move closer to each other, making it easier to remove the waste material on the tension strip, which is convenient to operate.

[0022] In one specific implementation, a fixing plate is provided on the side wall of the telescopic sleeve near the adjusting component, the fixing plate being used to limit the relative position between the fixing block and the adjusting block.

[0023] By adopting the above technical solution, when the fixing plate contacts the fixing block and the adjusting block, the relative position between the fixing block and the adjusting block can be restricted. Thus, when the waste material is wrapped around the tension strip, the tension strip will not be displaced under the pressure of the waste material, so that the tension strips on both sides are always kept open, which is convenient for winding up the waste material and also convenient for removing the wound waste material.

[0024] In one specific implementation, the tension bar has a clearance groove on the side facing the movable rod, the clearance groove passing through the tension bar, and the clearance groove is used to allow the movable rod to move.

[0025] By adopting the above technical solution and setting the avoidance groove, when the tension bars on both sides approach each other, the avoidance groove can give way to the movable rod, so as to avoid the tension bars and the movable rod from colliding as much as possible.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the waste material is being wound up, the distance between the tension bars on both sides is at its maximum. After winding is completed, the adjusting component moves the tension bars on both sides closer to each other, making it easy to remove the wound waste material from the tension bars. This makes the operation convenient.

[0028] 2. The waste material is wound up on the tension bar. The waste material is limited by the limit block and limit component to avoid the waste material from deviating during the winding process, so as to achieve a better winding effect.

[0029] 3. By setting a positioning sleeve and moving the positioning sleeve, when the positioning plate on the positioning sleeve contacts the telescopic block and the connecting block, it can restrict the relative rotation between the telescopic block and the connecting block. Then, the rotating sleeve is pressed against the positioning sleeve to position the positioning sleeve and keep the limit strips on both sides in an open state. During the process of winding up the waste material, the telescopic sleeve is kept stable, thereby achieving a better winding effect. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] This application discloses a waste collection device for blister packs, referring to... Figure 1 The waste collection device for the blister pack includes a rotating shaft 1, on which a motor (not shown in the figure) is connected. The motor drives the rotating shaft 1 to rotate, facilitating the winding of waste. A movable rod 2 is sleeved on the outer side of the rotating shaft 1. A moving groove 21 is formed on the inner wall of the movable rod 2 along its axis. A moving block 22 is fixed on the outer wall of the rotating shaft 1 and is slidably installed in the moving groove 21. The movable rod 2 and the rotating shaft 1 can move relative to each other. When the motor drives the rotating shaft 1 to rotate, it can also drive the movable rod 2 to rotate simultaneously.

[0039] Reference Figure 1Tensioning strips 3 are provided on both sides of the movable rod 2. A material head block 31 is fixed to the outer wall of the tensioning strip 3. The material head block 31 is Z-shaped and is used to secure the material head of the waste material before winding it up, facilitating winding. An adjustment assembly 4 is provided between the tensioning strip 3 and the movable rod 2. The adjustment assembly 4 is used to adjust the distance between the tensioning strips 3 on both sides of the movable rod 2. One or more sets of adjustment assemblies 4 are provided; in this embodiment, two sets are specifically provided. The two sets of adjustment assemblies 4 are located at both ends of the tensioning strip 3 along its length, ensuring that the distance between the two ends of the tensioning strips 3 remains consistent when adjusting the angle between them. The adjustment assembly 4 includes a fixing block 41 and an adjusting block 42. The fixing block 41 is fixedly sleeved on the movable rod 2, and the adjusting block 42 is located on both sides of the fixing block 41 and hinged to it. The end of the fixing block 41 furthest from the movable rod 2 is hinged to the tensioning strip 3. With the arrow in the diagram pointing downwards, the lower corners of both ends of the fixed block 41 are right angles, and the upper corner of the fixed block 41 is a rounded corner. The right angles restrict the adjusting block 42 from rotating counterclockwise around the hinge axis, making the connection between the fixed block 41 and the adjusting block 42 a one-way hinge. In the position shown in the diagram, the adjusting block 42 can only rotate clockwise around the hinge point. Before installing the rotating shaft 1 onto the motor, the operator holds the tension bar 3 with one hand and pushes the movable rod 2 with the other hand, pushing the movable rod 2 to... Figure 1 When the lever is in the middle position, it is at its limit position, and the movable lever 2 can no longer be pushed, so that the distance between the tension bars 3 on both sides is at its maximum value.

[0040] Reference Figure 1 A clearance groove 9 is provided on the side of the tension bar 3 facing the movable rod 2. The clearance groove 9 is opened along the length of the tension bar 3 and passes through the tension bar 3. The clearance groove 9 is an arc-shaped groove. When the tension bars 3 on both sides of the movable rod 2 approach each other, the clearance groove 9 can make way for the movable rod 2, so as to avoid collision between the tension bar 3 and the movable rod 2 as much as possible.

[0041] The implementation principle of this embodiment is as follows: Before winding up the waste material, the operator holds the tension bar 3 with one hand and pushes the movable rod 2 with the other hand to maximize the distance between the tension bars 3 on both sides of the movable rod 2. Then, the material head is fixed on the material head block 31, and the motor drives the rotating shaft 1 to rotate. The rotating shaft 1 drives the movable rod 2 and the tension bars 3 to rotate synchronously, thereby winding up the waste material. After winding is completed, the rotating shaft 1 is separated from the motor. The operator holds the waste material with one hand and pulls the movable rod 2 with the other hand. The movable rod 2 drives the fixed block 41 to move, causing the adjusting block 42 to rotate around the hinge point, which drives the tension bars 3 on both sides to move closer to each other, thus facilitating the removal of the wound waste material from the tension bars 3. The operation is convenient.

[0042] Example 2:

[0043] Reference Figure 2The difference between this embodiment and Embodiment 1 is that one end of the tension bar 3 is provided with a limiting block 5 for limiting the waste material, and the limiting block 5 is coaxially fixed on the rotating shaft 1. The limiting block 5 is a cylinder, and the diameter of the limiting block 5 is greater than the maximum distance between the two tension bars 3. An installation groove 91 is provided on the side wall of the limiting block 5 facing the tension bar 3. The installation groove 91 is a T-shaped groove, and one end of the tension bar 3 is slidably installed in the installation groove 91. The installation groove 91 is used to limit the tension bar 3, so that the tension bar 3 can only move radially along the limiting block 5 and cannot move axially along the limiting block 5. The other end of the tension bar 3 is provided with a limiting component 6 for limiting the waste material. Both the limiting component 6 and the limiting block 5 limit the waste material wound on the tension bar 3, which can minimize the deviation of the waste material during the winding process, thereby ensuring the winding effect of the waste material.

[0044] Reference Figure 2 The limiting component 6 includes a transition strip 61 and a limiting strip 62 disposed on both sides of the movable rod 2. The transition strip 61 is hinged to the tensioning strip 3, and the limiting strip 62 is hinged to the end of the transition strip 61 away from the tensioning strip 3. The maximum distance between the two limiting strips 62 is greater than the maximum distance between the two tensioning strips 3, so that the limiting strip 62 can limit the waste material on the tensioning strip 3.

[0045] Reference Figure 2 and Figure 3 A telescopic assembly 7 is provided between the two limiting strips 62 on both sides. The telescopic assembly 7 is used to adjust the distance between the two limiting strips 62 on both sides. The telescopic assembly 7 includes a telescopic sleeve 71, a telescopic block 72, and a connecting block 73. The telescopic sleeve 71 is slidably sleeved on the movable rod 2. A sliding block 74 is fixed on the outer wall of the movable rod 2. A sliding groove 75 is opened on the inner wall of the telescopic sleeve 71, and the sliding block 74 is slidably installed in the sliding groove 75. The telescopic block 72 is fixedly sleeved on the telescopic sleeve 71. A connecting block 73 is hinged to both ends of the telescopic block 72, and the connecting block 73 is hinged to the limiting strip 62. A fixing plate 76 is fixed to one end of the telescopic sleeve 71 facing the limiting block 5. The fixing plate 76 is used to limit the relative position between the fixing block 41 and the adjusting block 42.

[0046] Reference Figure 3 and Figure 4 , Figure 4 Figure a shows a schematic diagram of the waste collection device for blister packs in use. Figure 4Figure b shows a schematic diagram of the unloading state after winding is completed. When in the winding state, the telescopic block 72 is parallel to the connecting block 73, and both the connecting block 73 and the telescopic block 72 are perpendicular to the limiting strip 62. At this time, the sliding block 74 is in contact with the inner wall of the sliding groove 75 near the telescopic block 72, and the fixing plate 76 is in contact with the fixing block 41 and the adjusting block 42. With the arrow in the figure pointing downwards, after winding is completed, hold the tension strip 3 with one hand and pull the telescopic sleeve 71 downwards with the other hand. The telescopic sleeve 71 drives the telescopic block 72 downwards, and the connecting block 73 rotates around the hinge point between the connecting block 73 and the limiting strip 62, causing the limiting strips 62 on both sides to move closer together. When the telescopic sleeve 71 moves to the point where the sliding block 74 and the inner wall of the sliding groove 75 are in contact with the telescopic block 72, the telescopic sleeve 71 drives the movable rod 2 downwards, thereby causing the tension strips 3 on both sides to move closer together, until... Figure 4 As shown in b, this facilitates the removal of waste material from the tension bar 3.

[0047] Reference Figure 4 A limiting cavity 51 is formed inside the limiting block 5, and the movable rod 2 extends into the limiting cavity 51. A push plate 52 is provided inside the limiting cavity 51 and is fixed on the movable rod 2. A discharge rod 53 is fixed on the side wall of the push plate 52 facing the adjusting component 4, and a through groove 54 is formed on the side wall of the limiting block 5 facing the adjusting component 4 for the discharge rod 53 to pass through.

[0048] Reference Figure 4 When the telescopic sleeve 71 moves the movable rod 2 downward, the movable rod 2 moves the push plate 52 downward, and the push plate 52 moves the discharge rod 53 downward. The discharge rod 53 can push the waste material on the tension bar 3 downward, so that the wound waste material can be removed from the tension bar 3 more easily.

[0049] Reference Figure 2 and Figure 3 A positioning sleeve 8 is slidably fitted onto the telescopic sleeve 71. A positioning groove 81 is formed on the inner wall of the positioning sleeve 8. A positioning block 82 is fixed to the outer wall of the telescopic sleeve 71, and the positioning block 82 is slidably installed within the positioning groove 81. A positioning plate 83 is fixed to the outer wall of the positioning sleeve 8 near the telescopic component 7. The positioning plate 83 is used to limit the relative position between the telescopic block 72 and the connecting block 73. A thread is provided on the outer wall of the telescopic sleeve 71, and a rotating sleeve 84 is threaded onto the telescopic sleeve 71. The rotating sleeve 84 is located at the end of the positioning sleeve 8 away from the telescopic component 7. A rotating groove 85 is formed on the outer wall of the rotating sleeve 8, and an annular groove 86 is formed on the outer wall of the positioning sleeve 8. A connecting rod 87 is provided between the positioning sleeve 8 and the rotating sleeve 84, with one end of the connecting rod 87 located within the annular groove 86 and the other end located within the rotating groove 85. The annular groove 86 is a T-shaped groove. The end of the connecting rod 87 near the annular groove 86 is fixed with a mounting block 88. The mounting block 88 is slidably installed in the annular groove 86, which can minimize the separation of the connecting rod 87 from the positioning sleeve 8.

[0050] Reference Figure 2 and Figure 3 After winding, hold the waste material with one hand and rotate the rotating sleeve 84 with the other. The rotating sleeve 84 moves downward, which in turn moves the positioning sleeve 8 downward, allowing it to move out from between the limiting strips 62 and release the limitation on the telescopic component 7. This makes it easy to remove the wound waste material. When it is time to wind the next roll of waste material, hold the rotating shaft 1 with one hand and rotate the rotating sleeve 84 upward with the other. Under the limiting action of the mounting groove 91, when the bottom wall of the rotating groove 85 contacts the connecting rod 87, the rotating sleeve 84 drives the positioning sleeve 8 to rise, causing the positioning plate 83 to contact the connecting block 73 and the telescopic block 72. The positioning plate 83 restricts the relative rotation between the connecting block 73 and the telescopic block 72. The fixing plate 76 contacts the fixing block 41 and the adjusting block 42, restricting the relative rotation between the fixing block 41 and the adjusting block 42. When winding the waste material, keep the tensioning strips 3 on both sides taut to facilitate winding.

[0051] The implementation principle of this embodiment is as follows: When both the tension bar 3 and the limiting bar 62 are in the extended state, the material head is fixed on the material head block 31, and the rotating shaft 1 is driven to rotate by the motor to achieve the winding of the waste material. After winding is completed, the rotating shaft 1 is separated from the motor. The rotating sleeve 84 is rotated to move the positioning sleeve 8 out from between the limiting bars 62, and then the telescopic sleeve 71 is moved downward. The telescopic sleeve 71 drives the limiting bars 62 on both sides to move closer to each other through the telescopic component 7. When the sliding block 74 is in contact with the top wall of the sliding groove 75, the telescopic sleeve 71 can drive the movable rod 2 to move downward. The movable rod 2 drives the tension bars 3 on both sides to move closer to each other through the adjusting component 4, and at the same time drives the push plate 52 and the discharge rod 53 to move downward. The discharge rod 53 pushes the waste material on the tension bar 3 downward, making it easier to remove the wound waste material from the tension bar 3.

[0052] After removing the waste material, push the telescopic sleeve 71 upwards. The telescopic sleeve 71, through the telescopic component 7, pushes out the limiting strips 62 on both sides, maximizing the distance between the limiting strips 62. When the bottom wall of the sliding groove 75 is in contact with the sliding block 74, the telescopic sleeve 71 can drive the movable rod 2 to rise. During the rise of the movable rod 2, it pushes out the tension strips 3 on both sides, maximizing the distance between the tension strips 3. At the same time, it pushes the discharge rod 53 into the limiting cavity 51, so that the discharge rod 53 does not affect the winding of the waste material. When the fixing plate 76 on the telescopic sleeve 71 is in contact with the fixing block 41 and the adjusting block 42, the fixing plate 76 limits the fixing block 41 and the adjusting block 42. Rotate the rotating sleeve 84 upwards. When the bottom wall of the rotating groove 85 contacts the connecting rod, the rotating sleeve 84 drives the positioning sleeve 8 to rise. When the positioning plate 83 on the positioning sleeve 8 is in contact with the connecting block 73 and the telescopic block 72, it can restrict the relative rotation between the connecting block 73 and the telescopic block 72, which facilitates the winding of the waste material.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
