DETAILED DESCRIPTION

[0019] The following will be described in detail in combination with the accompanying drawings Figures 1-4 The present application will be further described in detail.

[0020] The embodiment of the present application discloses a paperboard pressing and folding device for carton production and processing. Referring to Figures 1-2The utility model provides a paperboard press folding device for carton production and processing, including the upper conveying roller line 1 and lower conveying roller line 2 of installation on paperboard press frame, and the upper conveying roller line 1 and lower conveying roller line 2 are by a plurality of conveying rollers, chain transmission unit, power equipment composition, and the mobile cavity is set up on the conveying roller in the middle, and this structure provides the space basis for the installation and adjustment of upper pressure assembly 3 and lower pressure assembly 4.

[0021] Refer to Figure 2 Lower pressure assembly 4 includes the bidirectional screw two 401 of rotation installation in mobile cavity, and the two ends of bidirectional screw two 401 are all set with two mobile seat two 402, and can move towards or away, and mobile seat two 402 is installed with lower pressure wheel 403, and the lower end of lower pressure wheel 403 is located in the inside of liquid storage box 5.

[0022] Refer to Figure 3 Lower pressure wheel 403 includes two detachable half circle pressure disc 4031 of installation on mobile seat two 402, such as through bolt connection, and the outside of two half circle pressure disc 4031 is installed with elastic batten 4032, and the both ends of elastic batten 4032 are installed with collet chuck 4033. The surface of half circle pressure disc 4031 of lower pressure wheel 403 is set with the inner recess 6 of elastic batten 4032, and the both ends of inner recess 6 are set with the clamping groove 7 of cooperation with collet chuck 4033, and two half circle pressure disc 4031 are combined, realize the closure of clamping groove 7, prevent elastic batten 4032 from falling off. When disassembling, only need to separate two half circle pressure disc 4031.

[0023] Refer to Figure 2 Upper pressure assembly 3 includes the bidirectional screw one 301 of rotation installation in mobile cavity, and the both ends of bidirectional screw one 301 are all set with mobile seat one 302, and two mobile seat one 302 can move towards or away, and mobile seat one 302 is installed with upper pressure wheel 303. Upper pressure wheel 303 includes two detachable half circle wheel disc 3031 of installation on mobile seat one 302, and the surface of half circle wheel disc 3031 is installed with indentation protrusion 3032.

[0024] Refer to Figure 4 When working, the distance of two mobile seat one 302 can be adjusted by rotating bidirectional screw one 301, so as to adjust the position of the indentation of paperboard. The half circle wheel disc 3031 of upper pressure wheel 303 and indentation protrusion 3032 thereon cooperate with the half circle pressure disc 4031 of lower pressure wheel 403 to form uniform indentation on paperboard. Because the elastic batten 4032 on the surface of lower pressure wheel 403 can be deformed under force, the pressure can be evenly distributed on the paperboard, to ensure that the paperboard is not damaged due to excessive local pressure.

[0025] Refer toFigure 2 The liquid in the liquid storage box 5 can infiltrate the elastic strip 4032 of the lower pressing wheel 403, so that the surface of the lower pressing wheel 403 remains wet. During the folding process, the wet lower pressing wheel 403 reduces the friction and heat accumulation with the paperboard, further protecting the paperboard from deformation or damage caused by high temperature or dryness.

[0026] Referring to Figure 2 The semicircular wheel disc 3031 is provided with a positioning column at one end of the bottom and a positioning hole at the other end, which can avoid misalignment when fixed.

[0027] Referring to Figure 3 The elastic strip 4032 can be made of rubber or silicone material, which can effectively absorb the liquid in the liquid storage box 5 and keep it wet. The depth of the lower pressing wheel 403 inside the liquid storage box 5 is between one fifth and one tenth of the wheel diameter, which can ensure that the surface of the lower pressing wheel can absorb a certain amount of water for lubrication, and the paperboard will not be damaged due to excessive moisture.

[0028] The implementation principle of the paperboard folding device for carton production and processing according to an embodiment of the application is as follows:

[0029] During the production and processing of cartons, first, the distance between the upper conveying roller line 1 and the lower conveying roller line 2 is adjusted according to the thickness and material of the paperboard. The distance between the two moving seats one 302 is adjusted by rotating the two-way screw rod one 301, and the distance between the two moving seats two 402 is adjusted by rotating the two-way screw rod two 401, so that the gap between the upper pressing wheel 303 and the lower pressing wheel 403 adapts to the folding requirement of the paperboard. At the same time, appropriate specifications of the semicircular wheel disc 3031 and the semicircular pressing disc 4031 can be selected and installed according to the needs.

[0030] Then, the paperboard to be folded is placed on the lower conveying roller line 2, and as the conveying roller rotates, the paperboard is conveyed between the lower pressing assembly 4 and the upper pressing assembly 3. When the paperboard passes through, the lower pressing wheel 403 keeps its surface wet due to the infiltration of the liquid in the liquid storage box 5 below, and the elastic strip 4032 contacts the paperboard to reduce friction and heat generation. At the same time, the indentation protrusion 3032 of the upper pressing wheel 303 cooperates with the semicircular pressing disc 4031 of the lower pressing wheel 403 to form uniform indentations on the paperboard, completing the folding operation.

[0031] During production, if different specifications of paperboard need to be produced, the equipment only needs to be paused, and the positions of the upper pressing wheel 303 and the lower pressing wheel 403 can be quickly adjusted, so that the production can continue without the need for large-scale adjustment and replacement of the entire device, greatly improving the production efficiency, reducing the production cost, and effectively reducing the waste rate.

[0032] Finally should be explained a few points are: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broad, can be mechanical or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change;
