Description

Technical Field

[0001] The utility model relates to the technical field of folding machinery, in particular to the technical field of paper towel stacking devices in a folding machine, and more specifically to a receiving member and a stacking device for a stacking device of a folding machine. Background Art

[0002] When extracting a pull-out tissue, the next tissue can be partially pulled out, which is convenient for users. This kind of pull-out tissue is divided into left and right groups. The left and right groups of tissues are folded towards each other. The upper half of each tissue is inserted into the folded tissue above, and the lower half of the tissue is inserted into the folded tissue below. In this way, cross-stacking is formed. When the uppermost tissue is extracted, the upper half of the next tissue will be pulled out.

[0003] At present, the folding of pull-out tissues is automatically folded by a folding machine. The paper towels are stacked on the support bracket from top to bottom. When the paper towels are stacked to a certain number, they are separated for packaging. During separation, a blocking member is inserted, and the subsequently folded papers are stacked on the blocking member. The receiving member moves downwards, and the papers on the supporting member move downwards accordingly, so as to separate the papers on the supporting member from the subsequent papers. Since the stacked tissues are stacked with the left and right groups of tissues facing each other, when the receiving member drives the stack of a set number of papers to move downwards, the upper half of the uppermost tissue in the paper stack is separated from the lower half of the lowermost tissue in the paper stack on the blocking member. The lower half of the lowermost tissue on the blocking member hangs down below the blocking member. When the receiving member rises again to receive a new paper stack on the blocking member, the hanging part of the tissue cannot be neatly folded on the receiving member.

[0004] ]When solving the problem of the hanging part of the lowermost tissue on the blocking member after the paper stack is separated, as Figure 1 shown, a separating member 11 is added on the opposite side of the blocking member 8. After the receiving member 1 moves down to complete the separation of the paper stack, the separating member 11 is inserted from the opposite side of the blocking member 8 below the blocking member 8 (as Figure 2 shown), folding the hanging part of the tissue on the blocking member 8 towards the bottom of the blocking member 8, and then the blocking member 8 is pulled out and reset (as Figure 3 shown), transferring the paper stack on the blocking member 8 to the separating member 11. When the receiving member 1 rises again to the paper stack receiving position, the blocking member 8 moves above the separating member 11 and is inserted into the folded tissues (as Figure 4 shown). The subsequently folded papers are stacked on the blocking member 8. Then the receiving member 1 moves to the position of the separating member 11, and the separating member 11 is pulled out, transferring the paper stack on the separating member 11 to the receiving member 1, so as to ensure the folding problem of the half tissue hanging on the blocking member 1 after the blocking member 8 and the receiving member 1 complete the separation of the paper stack.

[0005] In the above prior art, the problem of folding the half sheet of tissue paper hanging down on the blocking member is solved by adding a separating member. The actuating member of the added separating member is basically the same as that of the blocking member, and both include a reciprocating motion assembly in the X-axis direction and a reciprocating motion assembly in the Y-axis direction. This method has a complex structure and will increase the equipment cost of the paper separating device. Summary of the Utility Model

[0006] In order to overcome the defects and deficiencies existing in the above prior art, the present utility model provides a receiving member for a paper separating device of a folding machine. The invention object of the present utility model is to simplify the equipment structure of the paper separating device, reduce the equipment cost of the paper separating device, and solve the problem of folding the half sheet of tissue paper hanging down below the blocking member by using a simple structure. A blowing part for generating an air flow from the opposite side of the blocking member to fold the half sheet of tissue paper hanging down below the blocking member towards the bottom of the blocking member is arranged on the receiving member of the present utility model. By simply arranging a blowing part on the receiving member of the present utility model, the functions of the existing separating member can be realized, and components such as the existing separating member can be cancelled, simplifying the structure of the paper separating device and reducing the equipment cost of the paper separating device.

[0007] In order to solve the problems existing in the above prior art, the present utility model is realized by the following technical solutions.

[0008] The first aspect of the present utility model provides a receiving member for a paper separating device of a folding machine. The receiving member is connected to a vertical lifting drive assembly. The receiving member includes a receiving part for receiving a paper stack and a support connection part for connecting the receiving part to the vertical lifting drive assembly and supporting the receiving part. A blowing part is arranged at one end of the receiving part, and a plurality of air blowing holes for generating an air flow for folding the tissue paper hanging down below the blocking member towards the bottom of the blocking member are arranged on the blowing part.

[0009] The blowing part is located at the end of the receiving part extending outwards from the paper stacking channel.

[0010] The blowing part protrudes from the upper surface of the receiving part, and the air blowing holes include air blowing holes Ⅰ for generating an air flow parallel to the upper surface of the receiving part.

[0011] The air blowing holes on the blowing part further include air blowing holes Ⅱ for generating an obliquely upward air flow.

[0012] An air flow channel communicating with the air blowing holes and providing an air flow to the air blowing holes is arranged on the receiving part; an air flow channel communicating with the air flow channel on the receiving part is arranged on the support connection part.

[0013] In the second aspect of the present utility model, a folding and stacking device for a folding machine is provided, which includes a receiving member for receiving the paper towels that have been slit and folded in half, so as to stack the paper towels to form a paper stack; a blocking member for inserting above the paper stack on the receiving member after the paper stack has been stacked to a set number of layers, blocking the continuous stacking of the paper stack on the receiving member, and receiving the subsequent stacked paper towels.

[0014] The receiving member is connected to a vertical lifting drive assembly. The receiving member includes a receiving portion for receiving the paper stack and a support connection portion for connecting the receiving portion to the vertical lifting drive assembly and supporting the receiving portion. At one end of the receiving portion, a blowing portion is provided, and a plurality of air blowing holes for generating an air flow for folding the paper towels hanging below the blocking member towards the bottom of the blocking member are provided on the blowing portion.

[0015] The blowing portion is located at the end of the receiving portion extending outwards from the paper towel stacking channel.

[0016] The blowing portion protrudes from the upper surface of the receiving portion. The air blowing holes include air blowing holes Ⅰ for generating an air flow parallel to the upper surface of the receiving portion.

[0017] The air blowing holes on the blowing portion further include air blowing holes Ⅱ for generating an obliquely upward air flow.

[0018] An air flow channel communicating with the air blowing holes and providing air flow to the air blowing holes is provided on the receiving portion; an air flow channel communicating with the air flow channel on the receiving portion is provided on the support connection portion.

[0019] Compared with the prior art, the beneficial technical effects brought by the present utility model are as follows:

[0020] 1. A blowing portion for generating an air flow from the opposite side of the blocking member to fold the half sheets of paper towels hanging below the blocking member towards the bottom of the blocking member is provided on the receiving member of the present utility model. When the receiving member rises to prepare to receive the paper stack on the blocking member, the blowing portion generates an air flow to blow the paper towels hanging on the blocking member towards the bottom of the blocking member, so that the hanging paper towels change from a hanging state to a horizontal state. After the receiving member continues to move upwards to the position of the blocking member and catches the paper stack on the blocking member, the blocking member is withdrawn. After waiting for the paper stack on the receiving member to be stacked to the set number of layers, it is inserted into the stacked paper stack again. The subsequent stacked paper stacks fall on the blocking member, and so on. Only by the receiving member and the blocking member can the paper stack be stacked and separated. Compared with the existing method of adding separation claws for assistance, the structure is more simplified and the equipment cost is lower.

[0021] 2. In the present utility model, the blowing portion is arranged outside the paper towel stacking channel, and the air flow generated by it can be blown from outside the paper towel stacking channel to the inside, folding the hanging paper towels to a preset position, and the blowing effect of the air flow generated by the blowing portion is better.

[0022] 3. To further ensure and optimize the folding effect of the vertically hanging paper towels on the blocking member, the air blowing part is set to protrude from the receiving part, so that the air blowing part generates a horizontal airflow, which horizontally blows the vertically hanging paper towels from the outside of the paper towel stacking channel, ensuring that the vertically hanging paper towels are in a horizontal state when received by the receiving member. The horizontal airflow can ensure that they remain horizontal when received by the receiving member, ensuring the neatness of the paper stack.

[0023] 4. To further ensure the folding effect of the vertically hanging paper towels, two types of air blowing holes are set. One type of air blowing hole generates a horizontal airflow, and the other type of air blowing hole generates an obliquely upward airflow. The cooperation of the two types of airflows can better fold the vertically hanging paper towels to the horizontal. Specifically, when the distance between the receiving member and the blocking member is relatively far, that is, when the height of the air blowing part is lower than the lower edge of the vertically hanging paper towels, the air blowing hole II generates an obliquely upward airflow, and the vertically hanging paper towels are blown towards the bottom of the blocking member. As the receiving member rises, when the horizontal airflow generated by the air blowing hole I can act on the paper towels, the air blowing hole II stops blowing, and the horizontal airflow generated by the air blowing hole I blows the paper towels flat.

[0024] 5. To simplify the structure, the present utility model utilizes the receiving part and the support connecting part to form an air flow channel inside, which is convenient for the layout of the air blowing part and also reduces the layout of the air flow pipelines in the paper separating device, simplifies the structure, and reasonably optimizes the equipment space.

Detailed implementation manners

[0036] The following further elaborates on the technical solutions of the present utility model in conjunction with the accompanying drawings of the specification. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present at the same time, unless otherwise specified in this article.

[0038] Embodiment 1

[0039] As a preferred embodiment of the present utility model, referring to the accompanying drawings of the specification Figure 5 and the accompanying Figure 6 as shown, this embodiment discloses a receiving member 1 for the stacking and separating device of a folding machine. The receiving member 1 is connected to a vertical lifting drive assembly (not shown in the figure, and its structure is a conventional structure in the art, such as a servo motor synchronous belt lifting guide rail assembly, a servo motor lifting lead screw assembly, a servo motor lifting chain guide rail assembly, etc.). The receiving member 1 includes a receiving portion 2 for receiving a paper stack and a supporting and connecting portion 3 that connects the receiving portion 2 to the vertical lifting drive assembly and supports the receiving portion 2. At one end of the receiving portion 2, there is a blowing portion 4, and a plurality of blowing holes 5 for generating an air flow that folds the hanging paper towels 10 below the blocking member 8 towards the bottom of the blocking member 8 are provided on the blowing portion 4.

[0040] In this embodiment, an air blowing portion 4 is provided on the receiving member 1, which generates an air flow from the opposite side of the blocking member 8 to fold the half sheet of paper towel hanging below the blocking member 8 towards the bottom of the blocking member 8. When the receiving member 1 rises to prepare to receive the paper stack on the blocking member 8, the air blowing portion 4 generates an air flow to blow the paper towel 10 hanging on the blocking member 8 towards the bottom of the blocking member 8, so that the hanging paper towel 10 changes from the hanging state to the horizontal state. After the receiving member 1 continues to move upward to the position of the blocking member 8 and catches the paper stack on the blocking member 8, the blocking member 8 is withdrawn. After the paper stack on the receiving member 1 is stacked to the set number of layers, the blocking member 8 is inserted into the stacked paper stack again. The subsequent stacked paper stacks fall on the blocking member 8, and so on. Only by the receiving member 1 and the blocking member 8 can the paper stack stacking and separating be realized. Compared with the existing method of adding separation claws for assistance, the structure is more simplified and the equipment cost is lower.

[0041] Further preferably, the air blowing portion 4 is located at the end of the receiving portion 2 extending outward from the paper towel stacking channel 9. By arranging the air blowing portion 4 outside the paper towel stacking channel 9, the air flow generated by it can be blown from the outside of the paper towel stacking channel 9 inward to fold the hanging paper towel 10 to the preset position, and the air blowing effect of the air blowing portion 4 is better.

[0042] Further preferably, in order to further ensure and optimize the folding effect of the paper towel hanging on the blocking member 8, the air blowing portion 4 is protruded from the receiving portion 2, so that the air blowing portion 4 generates a horizontal air flow to horizontally blow the hanging paper towel 10 from the outside of the paper towel stacking channel 9, ensuring that the hanging paper towel 10 is in the horizontal state when being received by the receiving member 。The horizontal air flow can ensure that it remains horizontal when being received by the receiving member 1, ensuring the neatness of the paper stack.

[0043] In order to further ensure the folding effect of the hanging paper towel, two types of air blowing holes 5 are provided. One type of air blowing hole 5 generates a horizontal air flow, and the other type of air blowing hole 5 generates an obliquely upward air flow. The cooperation of the two types of air flows can better fold the hanging paper towel 10 to the horizontal. Specifically, when the receiving member 1 is far from the blocking member 8, that is, when the height of the air blowing portion 4 is lower than the lower edge of the hanging paper towel, the air blowing hole II 7 generates an obliquely upward air flow to blow the hanging paper towel 10 towards the bottom of the blocking member 8. As the receiving member 1 rises, when the horizontal air flow generated by the air blowing hole I 6 can act on the paper towel, the air blowing hole II 7 stops blowing, and the horizontal air flow generated by the air blowing hole I 6 blows the paper towel flat.

[0044] In order to simplify the structure, the utility model utilizes the receiving portion 2 and the support connection portion 3 to form an air flow channel inside, which is convenient for the layout of the air blowing portion 4, and also reduces the layout of the air flow pipeline in the separating device, simplifies the structure, and reasonably optimizes the equipment space.

[0045] Refer to the attached drawings of the specification Figure 7 to the attached drawings of the specification Figure 10As shown in the figure, this embodiment also provides a folding and stacking device for a folding machine, which includes a receiving member 1 for receiving the paper towels that have been slit and folded in half, and stacking the paper towels to form a paper stack; a blocking member 8 (the driving structure of the blocking member 8 is the same as the existing structure, and this application does not limit it) that is inserted above the paper stack on the receiving member 1 after the paper stack has been stacked to a set number of layers, blocking the continuous stacking of the paper stack on the receiving member 1, and receiving the subsequent stacked paper towels; the receiving member 1 is connected to a vertical lifting drive assembly, and the receiving member 1 includes a receiving portion 2 for receiving the paper stack and a support connection portion 3 that connects the receiving portion 2 to the vertical lifting drive assembly and supports the receiving portion 2; a blowing portion 4 is provided at one end of the receiving portion 2, and a plurality of air blowing holes 5 are provided on the blowing portion 4 for generating an air flow that folds the paper towel 10 hanging below the blocking member 8 towards the bottom of the blocking member 8.

[0046] As Figure 7 shown in the figure, the figure shows the state where the receiving member 1 rises to prepare to receive the paper stack received on the blocking member 8 after the output of the previous paper stack is completed. As the receiving member 1 rises, when the receiving member 1 rises to the lower edge position of the hanging paper towel 10, an air flow is generated on the blowing portion 4 that blows from the outside of the paper towel stacking channel 9 towards the inside, causing the hanging paper towel 10 to move towards the lower part of the blocking member as Figure 8 shown in the figure. As the receiving member 1 moves up, the hanging paper towel 10 is blown to a horizontal state.

[0047] As Figure 9 shown in the figure, after the hanging paper towel 10 is horizontal, the receiving member 1 receives the stacked paper stack from the blocking member 8, and then the blocking member 8 is withdrawn. As Figure 10 shown in the figure, when the receiving member 1 receives the paper towels of the set number of layers again, the blocking member 8 is inserted into the stacked paper stack, and the receiving member 1 quickly moves downwards to achieve the folding and stacking of the paper stack, and the subsequent stacked paper towels are received by the blocking member 8.
