Description

Technical Field

[0001] This invention relates to a corrugated cardboard box production equipment, and more particularly to a creasing device for producing corrugated cardboard. Background Technology

[0002] With the emergence of various special requirements and specifications for products, there is a need to design and manufacture corrugated boxes of corresponding sizes to facilitate logistics and transportation. During the production of corrugated boxes, creasing equipment is used to press corresponding creases onto the corrugated cardboard. Different specifications and sizes of corrugated boxes have different crease positions and shapes; therefore, the settings of the creasing equipment need to be adjusted for different corrugated boxes. The most common existing technology involves using creasing rollers to press creases onto the surface of the corrugated cardboard. Different shapes and positions of creases are produced by adjusting the type of creasing roller, the creasing depth, and the position of the creasing roller.

[0003] However, in actual production, the output of corrugated boxes of the same specifications and dimensions is sometimes small. When changing products, it is necessary to frequently adjust the position and type of the creasing rollers. Currently, most creasing rollers are fixedly installed via a rotating shaft, requiring the entire roller to be replaced, which is time-consuming and labor-intensive. Furthermore, to enable the creasing rollers to rotate, a rotation drive device is installed on the side of the roller shaft; when adjusting or replacing the creasing rollers, the position of the drive device also needs to be adjusted simultaneously.

[0004] Therefore, it is necessary to design a creasing machine for producing corrugated cardboard that can efficiently adjust the type of creasing rollers, quickly adapt to the production needs of different creasing specifications, and easily adjust the creasing depth and position of the creasing rollers, without requiring different creasing roller drive structures.

The locking component can also drive the driving component to contact and disengage from the pressure roller. When the driving component contacts the pressure roller, it can drive the pressure roller to rotate. When the pressure roller is rotated and replaced, the driving gear only needs to be hidden inside the longitudinal moving component without disassembly, and the rotation of the turntable is not affected.

[0028] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings and preferred embodiments.

[0029] like Figure 1The diagram shows two common corrugated cardboard box creasing patterns, T1 and T2. Pattern T1 is formed by the mutual pressing of a double-raised pressure roller II and a single-raised pressure roller I on the corrugated cardboard surface. Pattern T2 is formed by the mutual pressing of two single-raised pressure rollers I on the corrugated cardboard surface. In actual production, other types of pressure rollers are also used, achieving more creasing patterns through different pressure depths and the staggered arrangement of upper and lower rollers. Different creasing patterns correspond to the requirements of different sizes of corrugated cardboard boxes, which are related to the thickness, material, surface printing requirements, and types of products to be contained in the corrugated cardboard box. Therefore, different pressure rollers need to be changed when producing corrugated cardboard boxes of different sizes in the factory. In production, small batches of corrugated cardboard boxes of different sizes are often produced, necessitating frequent replacement of pressure rollers. Currently, most creasing rollers in existing technologies are fixedly installed via a rotating shaft, requiring the entire roller to be replaced, which is time-consuming and labor-intensive. Meanwhile, a rotation drive device is also installed on the side of the embossing wheel to enable its rotation. When adjusting or replacing the embossing wheel, the position of the drive device also needs to be adjusted simultaneously. Furthermore, with Figure 1 Taking the T1 creasing pattern as an example, for two batches of carton creasing, if the previous batch of carton creasing requires the double-raised pressure roller II to be on top and the single-raised pressure roller I to be on the bottom, while the next batch of carton requires the double-raised pressure roller II to be on the bottom and the single-raised pressure roller I to be on top, even though both batches are producing T1 creasing, it is still necessary to change the positions of the upper and lower pressure rollers, which greatly reduces production efficiency.

[0030] To solve the above-mentioned technical problems and improve the production efficiency of corrugated cardboard box creasing, the present invention provides the following... Figure 2 The creasing equipment 1 shown is for producing corrugated cardboard.

[0031] like Figure 2 As shown, the creasing equipment 1 for producing corrugated cardboard includes an upper creasing assembly 100 and a lower creasing assembly 200. The upper creasing assembly 100 and the lower creasing assembly 200 are respectively disposed on the upper and lower sides of the corrugated cardboard T. During the leftward conveying of the corrugated cardboard T, the pressure rollers of the upper creasing assembly 100 and the lower creasing assembly 200 create indentations on the upper and lower surfaces of the corrugated cardboard T. The mounting axis X1 of the upper creasing assembly 100 and the lower creasing assembly 200 is perpendicular to the conveying plane X2 of the corrugated cardboard T. Both the upper creasing assembly 100 and the lower creasing assembly 200 are mounted on the frame of the creasing machine, and have the same structure, symmetrically arranged with respect to the conveying plane X2 of the corrugated cardboard T.

[0032] The structure of the upper indentation assembly 100 and the lower indentation assembly 200 will be described below using the upper indentation assembly 100 as an example. The upper indentation assembly 100 includes a frame 110, a transverse movement assembly 120, a longitudinal movement assembly 130, an indexing assembly 140, an indentation roller assembly 150, a locking assembly 160, and a drive assembly 170.

[0033] The frame 110 is located at the top of the upper indentation assembly 100 and is used to mount the upper indentation assembly 100. Figure 2 The frame 110 shown is a channel steel structure, with the channel opening facing upwards and the flat surface facing downwards for mounting the upper indentation assembly 100. Those skilled in the art will understand that the frame 110 is not limited to channel steel; it can also be made of conventional automated equipment frame structures such as I-beams, plate steel, stainless steel supports, or aluminum alloy frames.

[0034] A lateral movement assembly 120 is provided below the frame 110. The lateral movement assembly 120 is used to adjust the lateral position of the upper creasing assembly 100 relative to the conveying plane X2 of the corrugated cardboard T (i.e., perpendicular to the plane X2). Figure 2 (As shown in the lateral position of the plane), the lateral shifting component 120 can make the pressure rollers of the upper creasing component 100 and the lower creasing component 200 produce creasing at different lateral positions on the surface of the corrugated cardboard T. At the same time, the relative positions of the pressure rollers of the upper creasing component 100 and the lower creasing component 200 can be adjusted so that the pressure rollers of the upper creasing component 100 and the lower creasing component 200 can be directly opposite each other or staggered to achieve different creasing shapes.

[0035] Below the transverse moving assembly 120 is a longitudinal moving assembly 130. The longitudinal moving assembly 130 adjusts the distance between the upper creasing assembly 100 and the upper surface of the corrugated cardboard T, allowing the pressure roller to approach the corrugated cardboard T and thus adjusting the depth of penetration, i.e., the creasing depth. Different thicknesses of corrugated cardboard require different creasing depths. If the creasing is too shallow, it will be unusable; if it is too deep, the corrugated cardboard will crack, affecting the working strength of the corrugated cardboard box. Therefore, in practical use, the appropriate creasing depth needs to be adjusted using the longitudinal moving assembly 130 according to the thickness, material, and creasing pattern of the corrugated cardboard.

[0036] The following is combined with Figure 3 The frame 110, the transverse movement assembly 120, and the longitudinal movement assembly 130 of this application are described below. Figure 3As shown in the embodiment, the frame 110 adopts a channel steel structure with the channel opening facing upwards, and the bottom surface of the frame 110 is perpendicular to the mounting axis X1. The transverse movement assembly 120 is mounted on the lower plane of the frame 110. The transverse movement assembly 120 includes a transverse guide rail 121, a transverse base 122, a transverse drive component 123, and a transverse guide component 124. The transverse guide rail 121 is fixedly mounted on the lower surface of the frame 110, and the transverse base 122 is slidably mounted on the lower part of the frame 110 via the transverse guide rail 121. The transverse drive component 123 and the transverse guide component 124 are also provided between the transverse base 122 and the frame 110. The transverse drive component 123 is a conventional motor-driven screw and nut drive structure, which is fixedly installed on the lower surface of the frame 110. The transverse base 122 is sleeved on the screw of the transverse drive component 123 via the screw and nut. The transverse guide component 124 is a guide rod type guide component, and the transverse base 122 is sleeved on the guide rod of the transverse guide component 123. The transverse drive component 123 drives the transverse base 122 to move laterally along the frame 110.

[0037] like Figure 3 As shown, the transverse transfer base 122 has a horizontal first mounting surface S1, which is parallel to the conveying plane X2 of the corrugated cardboard T and perpendicular to the mounting axis X1. A longitudinal transfer assembly 130 is mounted on the lower part of the first mounting surface S1 of the transverse transfer base 122.

[0038] The longitudinal movement assembly 130 includes a longitudinal movement guide cylinder 131, a longitudinal movement base 132, and a longitudinal movement drive component 133. The longitudinal movement guide cylinder 131 is fixedly mounted on the first mounting surface S1 of the transverse movement base 122. The longitudinal movement guide cylinder 131 is a cylindrical structure extending vertically, with its axial direction coinciding with the mounting axis X1. The cylinder wall of the longitudinal movement guide cylinder 131 has two symmetrical longitudinal movement guide holes 131a about the mounting axis X1. The longitudinal movement guide holes 131a are elongated through holes, extending in the direction of the mounting axis X1.

[0039] A longitudinal transfer base 132 is slidably installed inside the longitudinal transfer guide cylinder 131. The longitudinal transfer base 132 is also a cylindrical structure that runs vertically through the cylinder. The longitudinal transfer base 132 includes a guide lug 132a, a longitudinal transfer base body 132b, and a mounting flange 132c. The outer diameter of the longitudinal transfer base body 132b is equal to the inner diameter of the longitudinal transfer guide cylinder 131, so that the longitudinal transfer base 132 can be slidably disposed inside the longitudinal transfer base 132. A guide lug 132a is provided at the top of the longitudinal guide cylinder 132b relative to the longitudinal guide hole 131a. The guide lug 132a on each side extends out of the longitudinal guide cylinder 131 after passing through the longitudinal guide hole 131a on the corresponding side. The shape of the guide lug 132a matches the shape of the longitudinal guide hole 131a. By limiting and guiding the guide lug 132a through the longitudinal guide hole 131a, the circumferential movement of the longitudinal guide cylinder 131 can be restricted, so that the longitudinal guide cylinder 131 can move up and down stably along the direction of the mounting axis X1.

[0040] Longitudinal drive components 133 are fixedly installed on both sides of the outer wall of the longitudinal guide cylinder 131, opposite to the longitudinal guide hole 131a. The longitudinal drive component 133 includes a longitudinal motor 133a, a longitudinal lead screw 133b, a lead screw fixing seat 133c, and a longitudinal drive nut 133d. The axis of the longitudinal lead screw 133b is parallel to the mounting axis X1. The longitudinal motor 133a is fixedly installed on the top of the longitudinal guide cylinder 131, and its output end is fixedly installed with the longitudinal lead screw 133b. The end of the longitudinal lead screw 133b is rotatably mounted on the lead screw fixing seat 133c, which is fixedly installed below the outer wall of the longitudinal guide cylinder 131. The longitudinal drive nut 133d is installed on the guide lug 132a extending outside the longitudinal guide cylinder 131, and is sleeved on the longitudinal lead screw 133b. Driven by the longitudinal movement motors 133a on the left and right sides, the longitudinal movement base 132 can move stably up and down within the longitudinal movement guide cylinder 131.

[0041] The lower end of the longitudinal transfer machine base cylinder 132b is provided with a mounting flange 132c, which has mounting through holes that are symmetrical about the mounting axis X1. The lower surface of the mounting flange 132c forms a horizontal second mounting surface S2, which is parallel to the conveying plane X2 of the corrugated cardboard T and perpendicular to the mounting axis X1.

[0042] An indexing assembly 140 is fixedly mounted on the second mounting surface S2 of the mounting flange 132c. Multiple sets of pressure roller assemblies 150 are mounted on the indexing assembly 140, each set containing pressure rollers of different shapes. The indexing assembly 140 can index the different shapes of the pressure roller assemblies 150 to the mounting axis X1. In other words, the indexing assembly 140 has multiple types of pressure rollers fixedly mounted on it, and it can index the required pressure roller to the working position to participate in the indentation work, thereby producing the desired indentation shape. This eliminates the need for frequent complete replacements, improving production efficiency.

[0043] Those skilled in the art will understand that the indexing assembly 140 in this application can be equipped with more than one set of pressure roller assemblies 150, such as two sets, three sets, four sets, etc. For ease of explanation, this application... Figure 1-6 In this embodiment, two sets of pressure roller assemblies 150 are installed on the indexing assembly 140.

[0044] like Figure 3 As shown, the indexing assembly 140 includes an indexing base 141, a turntable 142, and an indexing drive 143. The indexing base 141 is a generally circular disc structure, having an upper surface and a lower surface. A protruding turntable fixing shaft 141c is located at the center of the lower surface of the indexing base 141, and the turntable fixing shaft 141c has a turntable axis X3. A circular stepped staircase 141d with the turntable axis X3 as its rotation center is also formed on the lower surface of the indexing base 141. The upper surface of the indexing base 141 has a mounting platform 141a that matches the mounting flange 132c. The mounting platform 141a has a horizontal surface that is in close contact with the second mounting surface S2 and a longitudinal surface that is in close contact with the side periphery of the mounting flange 132c. The mounting platform 141a has a countersunk screw hole 141b that matches the mounting through hole of the mounting flange 132c. Additionally, the mounting platform 141a has a first circular through hole 141e that penetrates both the upper and lower surfaces of the indexing base 141. The central axis of the first circular through hole 141e coincides with the mounting axis X1. Several screws pass through the mounting through hole of the mounting flange 132c and are then tightened into the countersunk screw hole 141b on the mounting platform 141a, thus fixing the indexing base 141 onto the second mounting surface S2 at the bottom of the longitudinal transfer base 132.

[0045] When the indexing machine base 141 is fixedly installed on the second mounting surface S2 at the bottom of the longitudinal transfer machine base 132, the turntable axis X3 forms an angle with the mounting axis X1, that is, the lower surface of the indexing machine base 141 is inclined relative to the second mounting surface S2 to form an angle.

[0046] The turntable 142 is a circular cover structure symmetrical about the turntable axis X3. The turntable 142 has a turntable mounting through hole 142a at its center. The turntable 142 is rotatably mounted on the turntable fixed shaft 141c through the turntable mounting through hole 142a. A sliding bearing and a retaining ring are provided between the turntable mounting through hole 142a and the turntable fixed shaft 141c. The rotation of the turntable 142 on the indexing machine base 141 is realized by the sliding bearing, while the axial movement of the turntable 142 on the turntable fixed shaft 141c is restricted by the retaining ring. The turntable 142 has an edge step 142b extending upward along the turntable axis X3. The shape of the turntable edge step 142b matches the circular step 141d on the lower surface of the indexing machine base 141. At the same time, the turntable edge step 142b abuts against the circular step 141d on the lower surface of the indexing machine base 141 through a shim. The circular step 141d can axially limit the turntable 142 through the turntable edge step 142b, and at the same time improve the load-bearing capacity of the turntable 142 mounted on the indexing machine base 141.

[0047] A turntable drive gear 142c is provided on the outer periphery of the turntable edge step 142b. A rotation drive component 143 is fixedly mounted on the upper surface of the rotation base 141. The rotation drive component 143 includes a rotation drive component mounting bracket 143a, a rotation motor 143b, and a rotation gear 143c. The rotation drive component mounting bracket 143a is an L-shaped frame, fixedly mounted on the edge of the upper surface of the rotation base 141. The rotation motor 143b is fixedly mounted on the mounting bracket 143a, and the rotation gear 143c is fixedly mounted on the output shaft of the rotation motor 143b. The rotation gear 143c meshes with the turntable drive gear 142c provided on the outer periphery of the turntable edge step 142b. The rotation motor 143b can drive the turntable 142 to rotate around the turntable axis X3.

[0048] Two second circular through holes 142d are symmetrically arranged on the turntable 142 about the turntable axis X3. Each second circular through hole 142d has a central axis X4. By rotating the turntable 142, the central axis X4 of each second circular through hole 142d can be aligned with the mounting axis X1. A horizontal third mounting surface S3 is formed on the turntable 142 at a position facing outwards (i.e., towards the corrugated cardboard T) relative to the second circular through holes 142d. When the second circular through holes 142d rotate until their central axis X4 coincides with the mounting axis X1, the third mounting surface S3 is parallel to the conveying plane X2 of the corrugated cardboard T and perpendicular to the mounting axis X1.

[0049] Two pressure roller assemblies 150 are respectively mounted on two third mounting surfaces S3. Each pressure roller assembly 150 includes a pressure roller seat 151 and a pressure roller 152, with the pressure roller 152 rotatably mounted on the pressure roller seat 151. The pressure roller seat 151 includes a horizontal seat plate 151a and two vertical lugs perpendicular to the horizontal seat plate 151a. The pressure roller 152 is rotatably mounted between the two vertical lugs. The horizontal seat plate 151a is fixedly mounted on the third mounting surface S3 by bolts. A third circular through hole 151b is provided on the horizontal seat plate 151a, and the central axis of the third circular through hole 151b coincides with the central axis X4 of the second circular through hole 142d.

[0050] The following is combined with Figure 4-5 The structure of the locking component 160 of this application is described.

[0051] When the rotation of the turntable 142 causes one of the pressure roller assemblies 150 to be in the working position, that is, when the central axis of the third circular through hole 151b of the horizontal seat plate 151a of the pressure roller assembly 150 coincides with the central axis X4 of the second circular through hole 142d, in order to stabilize the pressure roller 152 in the working position and prevent it from jumping or shifting position, this application also provides a locking assembly 160 for locking the turntable 142.

[0052] like Figure 4-5 As shown, a partition 132d is provided inside the longitudinal traverse base 132. The partition 132d, the longitudinal traverse base cylinder 132b, and the mounting platform 141a form a space for mounting the locking assembly 160. The locking assembly 160 includes a locking cylinder 161, an electromagnet 162, and a return spring 163. The locking cylinder 161 includes a sliding plate 161a and a locking cylinder body 161b. The locking cylinder body 161b is a hollow cylindrical structure. The sliding plate 161a is provided extending circumferentially from the top of the locking cylinder body 161b. The sliding plate 161a is a circular disc, and its outer diameter is equal to the inner diameter of the longitudinal traverse base cylinder 132b. The locking cylinder 161 slides up and down inside the longitudinal traverse base cylinder 132b via the sliding plate 161a. The electromagnet 162 is mounted on the mounting platform 141a. One end of the return spring 163 is connected to the mounting platform 141a, and the other end is connected to the lower side of the sliding plate 161a. When the electromagnet 162 is not energized, the locking cylinder 161 moves upward under the elastic force of the return spring 163, causing the upper side of the sliding disk 161a to contact the lower side of the partition 132d (e.g., Figure 5 (As shown); when electromagnet 162 is energized, electromagnet 162 attracts sliding disk 161a, overcoming the elastic force of return spring 163, causing the lower side of sliding disk 161a to contact electromagnet 162 (as shown). Figure 4 (As shown).

[0053] like Figure 4As shown, when the electromagnet 162 is energized and the lower side of the sliding disk 161a contacts the electromagnet 162, the locking cylinder 161b moves downward. The lower end of the locking cylinder 161b passes through the first circular through hole 141e, the second circular through hole 142d, and finally enters the third circular through hole 151b. The outer diameter of the locking cylinder 161b is equal to the inner diameter of the second circular through hole 142d and the third circular through hole 151b. The locking cylinder 161b acts like a locking pin, inserted into the second circular through hole 142d and the third circular through hole 151b, thereby locking the rotation of the turntable 142. It should also be noted that the inner diameter of the first circular through hole 141e is larger than the inner diameter of the second circular through hole 142d and the third circular through hole 151b.

[0054] like Figure 5 As shown, when the electromagnet 162 is not energized, and the upper side of the sliding disk 161a contacts the lower side of the partition 132d, the locking cylinder 161 is at its uppermost position. At this time, the lower end of the locking cylinder body 161b is completely contained inside the first circular through hole 141e, and the lower end of the locking cylinder body 161b does not enter the second circular through hole 142d and the third circular through hole 151b. At this time, the rotation of the turntable 142 is released and it can rotate freely under the drive of the drive structure.

[0055] The following is combined with Figure 3-6 The structure of the driving component 170 of the present invention will be described.

[0056] like Figure 3-6As shown, the drive assembly 170 includes a pressure roller drive motor 171, a first transmission rod 172, and a second transmission rod 173. The drive motor 171 is fixedly installed above the partition 132d inside the longitudinal traverse base 132. The body of the drive motor 171 is fixed to the longitudinal traverse base cylinder 132b via a mounting plate 171b. The central axis of the drive motor 171 coincides with the mounting axis X1. The output end of the drive motor 171 faces the partition 132d, and a first bevel gear 171a is fixedly installed at the output end of the drive motor 171. A first transmission rod 172 is rotatably mounted on the partition 132d, adjacent to the drive motor 171, via a bearing. One end of the first transmission rod 172 extends upward beyond the partition 132d and is fixedly mounted with a second bevel gear 172a. The second bevel gear 172a meshes with the first bevel gear 171a for transmission. The other end of the first transmission rod 172 extends downward through the partition 132d to the first circular through hole 141e. A spline is provided on the first transmission rod 172 located below the partition 132d. The second transmission rod 173 is rotatably mounted on the locking cylinder 161 via bearings. A connecting plate 161c is provided inside the locking cylinder body 161b. The second transmission rod 173 is rotatably mounted on the connecting plate 161c corresponding to the position of the first transmission rod 172. The second transmission rod 173 is a hollow rod, and its inner diameter matches the outer diameter of the first transmission rod 172. Simultaneously, the second transmission rod 173 has a spline groove that matches the spline of the first transmission rod 172. The second transmission rod 173 is sleeved outside the first transmission rod 172, with its lower end extending beyond the lower end of the locking cylinder body 161b. A third bevel gear 173a is fixedly mounted at the lower end of the second transmission rod 173. The second transmission rod 173 can only rotate relative to the locking cylinder 161. When the locking cylinder 161 moves up and down under the control of the electromagnet 162 and the return spring 163, the locking cylinder 161 can drive the second transmission rod 173 to slide up and down relative to the first transmission rod 172.

[0057] A helical tooth 152a matching the third bevel gear 173a is provided on one side of the pressure roller 152. The length and position of the second transmission rod 173 meet the following requirements: 1) As Figure 3-4As shown, when the electromagnet 162 is energized, the lower side of the sliding disk 161a contacts the electromagnet 162, and the locking cylinder 161 drives the second transmission rod 173 to move to the lowest limit position. At this time, the third bevel gear 173 at the end of the second transmission rod 173 extends out of the third circular through hole 151b and meshes with the helical teeth 152a of the pressure roller 152. At this time, the drive motor 171 drives the first bevel gear 171a to rotate, the first bevel gear 171a drives the second bevel gear 172a to rotate, the second bevel gear 172a drives the first transmission rod 172 to rotate, the first transmission rod 172 drives the second transmission rod 173 to rotate via the spline, the second transmission rod 173 drives the third bevel gear 173a to rotate, and finally the third bevel gear 173a drives the pressure roller 152 to rotate via the helical teeth 152a; 2) As Figure 5 As shown, when the electromagnet 162 is not energized and the upper side of the sliding disk 161a contacts the lower side of the partition 132d, the locking cylinder 161 drives the second transmission rod 173 to move to the uppermost limit position. At this time, the third bevel gear 173 at the end of the second transmission rod 173 is completely retracted from the second circular through hole 142d and the third circular through hole 151b and does not enter the second circular through hole 142d and the third circular through hole 151b. At this time, the third bevel gear 173 at the end of the second transmission rod 173 will not affect the normal rotation of the turntable 142.

[0058] With the above structure, the turntable 142 of the upper indentation assembly 100 in this application can be simultaneously installed with, for example, Figure 1 The double-protruding pressure roller II and the single-protruding pressure roller I shown can also be simultaneously installed on the turntable 142 of the lower indentation assembly 200. Figure 1 The double-convex pressure roller II and single-convex pressure roller I shown can achieve rapid switching and rapid parameter control of various pressure roller combinations through the horizontal, vertical and rotational adjustment of the upper pressure assembly 100 and the lower pressure assembly 200. When the pressure roller needs to be replaced, only the pressure roller assembly 150 on the turntable 142 needs to be simply disassembled and assembled without disassembling the pressure roller rotation drive structure and the overall structure, which greatly improves the production efficiency when switching products in production.
