Abstract
Description
Technical Field
[0001] This application relates to the field of automated corrugated cardboard box processing equipment, and more particularly to a crimping and feeding mode for a cardboard box forming machine. Background Technology
[0002] The background description provided herein serves to give a general overview of the background of this application. The work of the currently identified inventors to the extent described in this background section, and aspects of this description that do not constitute prior art at the time of application, are neither expressly nor impliedly acknowledged as prior art in conflict with this application.
[0003] The process of processing cartons using existing carton forming machines involves the following steps: paper feeding by the leading edge module, paper feeding by the infeed module, slotting by the slotting module, creasing by the creasing module, cutting by the slitting module, paper feeding by the output module, and cross-cutting by the cross-cutting module. Because the creasing process follows the slotting process, the slotted edges of the cardboard are very prone to cracking during the creasing process. Furthermore, in existing creasing machines, the creasing rollers are positioned above a through shaft. When the cardboard passes between the creasing rollers and the through shaft, the creasing rollers press against the cardboard, while the cardboard is supported by the through shaft. This creasing method is commonly referred to in the art as point-to-flat creasing. In dry weather or when the cardboard quality is poor, with this creasing method, excessively deep creasing can cause the cardboard to crack easily, while insufficiently deep creasing makes it difficult to fold the carton flaps, and the creased areas are prone to cracking when the flaps are folded outwards, thus affecting the quality of the formed carton.
[0004] Therefore, improvements are needed to the existing carton forming machines. Utility Model Content

[0026] This application will now be further elaborated. In the following paragraphs, different aspects of this application are defined in more detail. Unless expressly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as preferred or advantageous may be combined with any other feature(s) indicated as preferred or advantageous.
[0027] To address the problems existing in the prior art, this application provides a creasing and feeding module for a carton forming machine. This creasing and feeding module can creasing the cardboard while feeding the paper, allowing the cardboard to undergo the creasing process before slotting, thus avoiding the problem of slot cracking that easily occurs when slotting is done first and then creasing. (See attached document.) Figure 1This paper illustrates a creasing and feeding module 100 according to the principles of this application. The creasing and feeding module 100 includes a first crossbeam 110, a first creasing and feeding wheel assembly 111, and a first drive mechanism 112. The first crossbeam 110 is provided with a first linear slide rail 113, and the first linear slide rail 113 is provided with a first slider 114, which is slidably connected to the first linear slide rail 113. The first creasing and feeding wheel assembly 111 is connected to both the first slider 114 and the first drive mechanism 112, allowing the first creasing and feeding wheel assembly 111 to slide along the first linear slide rail 113 via the first slider 114 under the drive of the first drive mechanism 112, thereby adjusting the position of the first creasing and feeding wheel assembly 111. The first creasing and feeding wheel assembly 111 can simultaneously creasing the cardboard while cooperating with a feeding component located on its opposite side to feed paper, thus allowing the creasing process to occur before the slotting process, effectively avoiding the problem of slot cracking that easily occurs when slotting is performed before creasing.
[0028] See attached document Figure 1 Appendix Figure 2 and attached Figure 3 In one embodiment, the first creasing and feeding roller assembly 111 includes a first creasing roller 115, a first feeding roller 116, and a first mounting base 117. The first creasing roller assembly 111 is connected to the first driving mechanism 112 and the first slider 114 via the first mounting base 117, meaning the first mounting base 117 is connected to both the first driving mechanism 112 and the first slider 114. The first creasing roller 115 is disposed on both sides of the first feeding roller 116. The number of first feeding rollers 116 can be one or more, such as three, four, or five. Alternatively, the first creasing roller 115 can also be disposed among multiple first feeding rollers 116. In an alternative embodiment, the creasing roller 115 in the first creasing and feeding roller assembly 111 can be replaced by a pressure plate (not shown). The pressure plate is connected to the first mounting base 117, thus functioning, like the first feeding roller 116, to press down the paperboard as it moves forward, preventing it from jumping. In some embodiments, the first creasing roller 115 can be integrally formed with the first paper feeding roller 116. In this case, the first creasing roller 115 can be provided only on one side of the first paper feeding roller 116. In some embodiments, the first creasing and paper feeding roller assembly 111 may also omit the first paper feeding roller 115 and rely solely on the first creasing roller 115 to press the paperboard. Those skilled in the art will readily understand that this is feasible for processing paperboards with smaller dimensions.
[0029] See attached document Figure 1 and attached Figure 2The first linear guide rail 113 can be provided in two forms. Alternatively, in some embodiments, depending on the size of the device and the requirements for the stability of the sliding connection, the first linear guide rail 113 can also be provided in one, three, or four forms. Accordingly, the first slider 114 can also be provided in the same number.
[0030] See attached document Figure 1 The first drive mechanism 112 can be a ball screw and nut mechanism. Alternatively, the first drive mechanism 112 can also be a gear and rack mechanism or a synchronous pulley and synchronous belt mechanism, or other mechanisms that can drive the first paper feeding roller group 111 to perform linear motion.
[0031] See attached document Figure 3 The first creasing and feeding roller assembly 111 may further include a creasing roller lifting device 118 and a feeding roller lifting device 119. The first creasing roller 115 can be connected to the first mounting base 117 via the creasing roller lifting device 118, and the first feeding roller 116 can be connected to the first mounting base 117 via the feeding roller lifting device 119, thereby facilitating the adjustment of the height of the first creasing roller 115 and the first feeding roller 116 individually or simultaneously as needed. The creasing roller lifting device 118 and the feeding roller lifting device 119 can be cylinders, hydraulic cylinders, or screw-nut devices, etc. Those skilled in the art will readily understand that any mechanism capable of driving the first creasing roller 115 and the first feeding roller 116 to perform linear motion in the vertical direction can be applied to this application.
[0032] See attached document Figure 4 and attached Figure 2 The creasing and feeding module 100 according to the principles of this application further includes a second crossbeam 120, a second creasing and feeding roller assembly 121, a second drive mechanism 122, and a motor 123. The second crossbeam 120 is arranged parallel to the first crossbeam 110. The second crossbeam 120 is provided with a second linear slide rail 124, and the second linear slide rail 124 is provided with a second slider 125, which is slidably connected to the second linear slide rail 124. The second creasing and feeding roller assembly 121 is connected to the second slider 125 and the second drive mechanism 122, respectively, so that the second creasing and feeding roller assembly 121 can slide along the second linear slide rail 124 under the drive of the second drive mechanism 122, thereby adjusting the position of the second creasing and feeding roller assembly 121. The motor 123 can be connected to the second creasing and feeding roller assembly 121, thereby driving the relevant components of the second creasing and feeding roller assembly 121 to rotate, so that it cooperates with the relevant components of the first feeding roller assembly 111, which is a driven component, to feed paper. Alternatively, the motor 123 can also be connected to the first crimping and feeding roller assembly 111, thereby driving the relevant components of the first crimping and feeding roller assembly 111 to rotate, so that it cooperates with the relevant components of the second feeding roller assembly 121, which is a driven component, to feed paper.
[0033] The second crease feeding roller group 121 can be slidably disposed opposite to the first crease feeding roller group 111, that is, the two are aligned. Normally, the first crease feeding roller group 111 is located at the upper part, and the second crease feeding roller group 121 is located at the lower part, thus enabling simultaneous crease feeding on both sides of the cardboard. Compared to crease feeding only on one side of the cardboard, the technical solution of this application creases both sides of the cardboard, forming crease lines on both sides, making the cardboard easier to bend and reducing the risk of breakage during bending. Simultaneously, compared to crease feeding only on one side, crease feeding both sides results in a smaller compression amount in the thickness direction on each side compared to crease feeding only on one side, but a greater overall compression amount in the thickness direction than when creases only on one side. This prevents the cardboard from breaking due to excessively deep creases and ensures that the cardboard achieves the necessary compression for bend-free bending.
[0034] See attached document Figure 5 The second creasing and feeding roller assembly 121 includes a second creasing roller 126, a second feeding roller 127, a second mounting base 128, and a drive shaft 129. The second creasing and feeding roller assembly 121 is connected to the second slider 125 and the second drive mechanism 122 via the second mounting base 128; that is, the second mounting base 128 is connected to the second slider 125 and the second drive mechanism 122. The second creasing roller 126 and the second feeding roller 127 are mounted on the drive shaft 129, which can be connected to the second mounting base 128 and a motor 123, thereby driving the second creasing roller 126 and the second feeding roller 127 to rotate coaxially via the motor 123. In some embodiments, the second creasing roller 127 is integrally formed and can be bolted to the second feeding roller 127, thereby increasing the stability of the second creasing roller 126. Alternatively, the second creasing roller 126 can also be separately formed and mounted on the drive shaft 129 using fasteners. In some embodiments, the second feed roller 127 can also be replaced by a shaft integrally formed with the drive shaft 129; in other words, the second feed roller 127 can be part of the drive shaft 129, thereby driving the paperboard forward via the drive shaft 129. Alternatively, in embodiments where the motor is connected to the first creasing and feeding roller assembly 111, the first creasing roller 115 and the first feed roller 116 can be mounted on a drive shaft (not shown), and the drive shaft can be connected to a motor to drive the first creasing roller 115 and the first feed roller 116 to rotate. In some embodiments, both the first creasing and feeding roller assembly 111 and the second creasing and feeding roller assembly 121 can be connected to a motor, so that both can operate under the drive of the motor.
[0035] The second crease roller 126 can be disposed on both sides of the second paper feeding roller 127. There can be one second paper feeding roller 127, and its length is longer than the first paper feeding roller 116 to increase the friction area between it and the paperboard, effectively driving the paperboard forward. Alternatively, there can be more than one second paper feeding roller 127, such as two or three. In these embodiments, the second crease roller 126 can also be disposed between the second paper feeding rollers 127. The first crease roller 115 and the second crease roller 126 can be single-line rollers, double-line rollers, triple-line rollers, cylindrical rollers, or arc-shaped rollers. Those skilled in the art will readily understand that single-line rollers, double-line rollers, and triple-line rollers refer to crease rollers with one, two, and three protruding ridges respectively arranged around their circumference.
[0036] See attached document Figure 6 According to the principles of this application, the creasing and feeding module 100 can be equipped with two sets of first creasing and feeding roller sets 111 and second creasing and feeding roller sets 121 respectively. During carton processing, creasing can be performed using the two inner creasing rollers 115 and second creasing rollers 126, or using the two outer creasing rollers 115 and second creasing rollers 126, depending on the size of the carton. In some embodiments, the first creasing and feeding roller sets 111 and second creasing and feeding roller sets 121 can also be set as one set, three sets, or four sets, etc., depending on the size of the cardboard.
[0037] See attached document Figure 7 and attached Figure 8 This application also provides a carton forming machine 10. The carton forming machine 10 according to the principles of this application includes a creased feeding module 100 according to the principles of this application. Advantageously, the carton feeding module 10 further includes a leading edge feeding module 200 and a slotting and creased module 300, wherein the creased feeding module 100 is disposed between the leading edge feeding module 200 and the slotting and creased module 300, thereby creased the cardboard before slotting to prevent slot breakage. Advantageously, the carton forming machine may also include a creased module 400, a slitting module 500, a paper output feeding module 600, and a cross-cutting module 700.
